ARCHSTONE-SMITH OPERATING TRUST
9200 E. Panorama Circle, Suite 400
Englewood, Colorado 80112

    •    , 2007

Dear Class A-1 Common Unitholder,

        On May 28, 2007, Archstone-Smith Trust and Archstone-Smith Operating Trust entered into an Agreement and Plan of Merger with affiliates of Tishman Speyer Real Estate Venture VII, L.P. and Lehman Brothers Holdings Inc. pursuant to which Archstone-Smith Operating Trust and Archstone-Smith Trust, the sole trustee of Archstone-Smith Operating Trust, would each merge with subsidiaries of a joint venture jointly controlled by affiliates of Tishman Speyer Real Estate Venture VII, L.P. and Lehman Brothers Holdings Inc.

        As more fully described in this prospectus/information statement, in connection with the merger of Archstone-Smith Operating Trust, you, as a holder of Class A-1 common units, will be entitled to receive, in exchange for your Class A-1 common units, one newly issued Series O preferred unit per existing Class A-1 common unit of Archstone-Smith Operating Trust. Alternatively, at your election, you may elect to receive in exchange for your Class A-1 common units (a) $60.75 per unit in cash, without interest and less applicable withholding taxes, or (b) a combination of the cash consideration and Series O preferred units. The cash consideration of $60.75 per unit that you are being offered the opportunity to elect to receive is the same per common share consideration that the shareholders of Archstone-Smith Trust will receive in connection with its merger. However, Archstone-Smith Trust's shareholders are not being offered the opportunity to elect to receive the Series O preferred units.

        As a holder of approximately 89.3% of all of our outstanding common units, Archstone-Smith Trust's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement, as amended. Archstone-Smith Trust intends to approve the mergers, which approval is expected to be effective 20 days after the date of this prospectus/information statement. As a result, you are not being asked to vote on either of the mergers, we are not asking you for a proxy and you are requested not to send a proxy pursuant to this prospectus/information statement. You only have the right to make an election with respect to the form of consideration that you will receive in connection with our merger. If you own common shares of Archstone-Smith Trust in addition to being a Class A-1 common unitholder, Archstone-Smith Trust has separately sent to you a proxy statement relating to its merger and its special meeting. In addition, as required by our declaration of trust, we have sent you a copy of the proxy statement relating to Archstone-Smith Trust's merger and its special meeting. However, there will not be any meeting of our unitholders to consider the mergers and the other transactions contemplated by the merger agreement.

        This prospectus/information statement explains the proposed transactions and the election that you have the right to make. It also includes copies of the merger agreement and our annual report on Form 10-K for the year ended December 31, 2006 and our quarterly report on Form 10-Q for the quarter ended March 31, 2007. We encourage you to carefully read them, including all the attachments and annexes, and the other documents that we have filed with the Securities and Exchange Commission that are incorporated by reference into this prospectus/information statement. In particular, you should carefully consider the risk factors that appear in this prospectus/information statement beginning on page 35. We maintain a website at www.archstonesmith.com. The information contained on the website is not part of, or incorporated in, this prospectus/information statement.

        If you do not make, or fail to properly make, an election, you will automatically receive one Series O preferred unit for each Class A-1 common unit that you own and you will not receive any cash consideration. As a result, in order for you to receive any cash consideration for your Class A-1 common units, you must properly complete and return the election form and all necessary attachments, all of which are contained and described in the election form package, which is attached to this prospectus/information statement as Attachment A, to Mellon Investor Services, LLC, the election agent for the election, by no later than    •    .

        There currently is no public trading market for the Class A-1 common units, and the terms of the Archstone-Smith Operating Trust declaration of trust will prohibit the trading of the Series O preferred units on any securities exchange. If all of the outstanding Class A-1 common unitholders elect to receive the Series O preferred units, it is expected that we will issue an aggregate of up to 27,219,023 Series O preferred units in connection with the Archstone-Smith Operating Trust merger.

        Thank you for your cooperation and continued support.

    Sincerely,

 

 

SIGNATURE

 

 

R. Scot Sellers

Archstone-Smith Operating Trust

    Series O preferred units do not and will not have a trading market and have restrictions on transferability.
    Series O preferred units constitute passive investments in the operating trust and you will have no management rights or control over our business or right to replace our sole trustee and will have limited governance rights, with MergerCo and its affiliates controlling substantially all matters.
    The termination of registration of our Class A-1 common units under the Exchange Act would substantially reduce the information required to be publicly furnished by us and would make certain provisions of the Exchange Act no longer applicable to us.

    We have restrictions on the sale of certain properties even if the sale of one or more such properties may be prudent or in our best interests.

the operating trust merger effective time (other than units held by holders who have properly exercised and perfected appraisal rights, if any, under Maryland law) will automatically be converted into the right to receive one Series O preferred unit.

        Enclosed with this prospectus/information statement as Attachment A is an election form package that contains the form, transmittal materials and other documents necessary in connection with making the election, which we refer to collectively as the "election form package."

        If you make no election or fail to properly make the election pursuant to the procedures set forth in this prospectus/information statement and the election form package, or if you revoke your election and do not submit a new election form prior to the election deadline, you will automatically be entitled to receive one Series O preferred unit for each Class A-1 common unit that you own immediately prior to the operating trust merger effective time and you will not receive any cash consideration for your Class A-1 common units.

Questions and Answers About the Election, the Series O Preferred Units and Certain Tax Considerations

Q:    What is the proposed transaction?

A:
The proposed transaction is the acquisition of the company by Parent and its affiliates pursuant to the terms and conditions set forth in the merger agreement. If the company's shareholders vote to approve the company merger and the other transactions contemplated by the merger agreement, and the other closing conditions under the merger agreement are satisfied or waived, Operating Trust MergerSub will merge with and into the operating trust, with the operating trust surviving. Immediately after the operating trust merger effective time, the company will merge with and into MergerCo, with MergerCo surviving the company merger and Parent and its affiliates owning all of the outstanding common shares of MergerCo. These transactions are expected to occur on the same date. For additional information about the mergers, please review the merger agreement attached to this prospectus/information statement as Annex A and incorporated by reference into this prospectus/information statement. We encourage you to read the merger agreement carefully and in its entirety, as it is the principal document governing the mergers.

Q:    Why am I receiving this prospectus/information statement?

A:
This prospectus/information statement is being provided to you to inform you of an important choice you need to make in connection with the election and to provide you with important information regarding the election, the terms of the Series O preferred units and the proposed mergers pursuant to the merger agreement.

Q:    What will I receive in the operating trust merger?

A:
In connection with the operating trust merger, you, as a Class A-1 common unitholder, will automatically be entitled to receive, for each Class A-1 common unit that you own, one newly issued Series O preferred unit. Alternatively, you have the right to elect to receive (a) $60.75 per unit in cash, without interest and less applicable withholding taxes or (b) a combination of the cash consideration and Series O preferred units. The cash consideration of $60.75 per Class A-1 common unit that you are being offered the opportunity to elect to receive is the same per common share consideration that the shareholders of the company will receive in connection with the company merger. However, the company's common shareholders are not being offered the opportunity to elect to receive the Series O preferred units. In order for you to receive any cash consideration for your Class A-1 common units, you must timely deliver a properly completed and executed election form, that is not revoked, accompanied by all necessary attachments, all as described below.

Q:    How do I specify whether I want to receive cash or Series O preferred units as consideration in connection with the operating trust merger?

A:
The terms and conditions of the election, as well as instructions related to the procedures and conditions for making the election, are described in detail in the election form package, attached as Attachment A to this prospectus/information statement. You should carefully read and follow the instructions contained in the election form package.

Q.    What is the deadline for making the election?

A.
The deadline for submitting your properly completed and executed election form, accompanied by all necessary attachments, to Mellon Investor Services, LLC, at the address given in the election form package, is 5:00 P.M. New York City Time, on    •    ,    •    , 2007. If Mellon Investor Services, LLC, has not received your properly completed and executed election form, accompanied by all necessary attachments, or if you have revoked a previously submitted election that was

Q.    How do I elect to receive the cash consideration for my Class A-1 common units?

A.
In order to elect to receive any cash consideration for your Class A-1 common units, you must properly complete, execute and return the documents described below, in accordance with the instructions in the election form package included as Attachment A, by the election deadline:

complete the election form according to the instructions provided in the election form package (if you are a married individual, your spouse may be required to sign the spousal consent to the election), including specifying the number of Class A-1 common units, if less than all, for which you are electing to receive the cash consideration;

if you are a U.S. person, complete and sign the Substitute Form W-9 (located in Box 2 on the front of the election form), or if you are not a U.S. person for U.S. federal income tax purposes, request from us, and complete, sign and return an appropriate Form W-8; and

if you are a U.S. person, complete and sign the FIRPTA certificate (Attachment 1A to the election form for individuals or Attachment 1B to the election form for entities).

Q:    What do I need to do to receive Series O preferred units in the operating trust merger?

A.
If you wish to receive only Series O preferred units for your Class A-1 common units, and we did not issue to you a certificate representing your Class A-1 common units, then you may, but are not required to, complete, execute and return the documents included in the election form package by the election deadline. If you do not submit a properly completed election form prior to the election deadline, you will automatically be entitled to receive Series O preferred units in the operating trust merger in exchange for your Class A-1 common units. However, if you received a

Q:    What happens if I fail to make a timely, valid election?

A.
Class A-1 common unitholders who do not make a timely, valid election as provided in the election form package will be entitled to receive one Series O preferred unit for each Class A-1 common unit that they own and will not be entitled to receive any cash consideration.

Q:    Can I elect to receive a combination of cash and Series O preferred units?

A.
Yes. Partial or combination elections are permitted. In order to receive cash consideration with respect to some but not all of your Class A-1 common units, you must specify the number of whole Class A-1 common units for which you are electing to receive the cash consideration. You cannot elect to receive fractional Series O preferred units or cash consideration for less than a whole number of Class A-1 common units. If you do not clearly specify the allocation, even if you otherwise properly complete, execute and return the election form and all necessary attachments by the election deadline, you will only be entitled to receive the Series O preferred units for all of your Class A-1 common units. As a result, if you wish to receive any cash consideration, it is very important that you specify your allocation when you timely return a properly completed and executed election form package by the deadline.

Q:    How does the cash consideration compare to the current value of my Class A-1 common units?

A.
There currently is no public trading market for the Class A-1 common units. However, since Class A-1 common units are redeemable by the holder for the company's common shares on a one-for-one basis or a cash equivalent thereof, we generally consider the value of one Class A-1 common unit the same as the trading common share price. The cash consideration of $60.75 per unit that our Class A-1 common unitholders may elect to receive in the operating trust merger represents an approximate 22.7% premium over the last trading price of the company's common shares on May 24, 2007 immediately prior to published reports on such day regarding a potential acquisition involving us, an approximate 15.4% premium to the weighted average closing price of the company's common shares for the 30-day period ended May 25, 2007, the last trading day before the public announcement of the merger agreement, and an approximate 10.3% premium to the weighted average closing price of the company's common shares for the one-year period ended May 25, 2007. You are encouraged to obtain current market quotations for the company's common shares prior to making the election.

Q:    Can I revoke or change my election?

A.
Yes. You may revoke any properly completed and timely delivered election at any time prior to    •    , 2007, the election deadline, by submitting to Mellon Investor Services, LLC a completed and executed revocation of election form (Attachment 2 to the election form). Any effective election properly revoked will be deemed not to have been validly made, and you must properly complete and execute a new election form and the related forms, and return them prior to the election deadline in order to make a new valid election. If you properly revoke an effective election but do not make a new valid election by the election deadline, you will only be entitled to receive Series O preferred units for all of your Class A-1 common units. The reasonable determination of the company, after consultation with the buyer parties, shall be binding as to whether elections to receive the cash consideration have been properly made or revoked.

Q:    When will I receive the cash consideration or Series O preferred units, as applicable?

A:
If you properly elect to receive full or partial cash consideration for all or part of your Class A-1 common units by timely and properly completing, executing and returning the election form and all necessary attachments, including the Substitute Form W-9 (located in Box 2 on the front of the election form) and FIRPTA certificate (Attachments 1A or 1B to the election form), to Mellon Investor Services, LLC, on or prior to the election deadline, you will receive such cash consideration from the paying agent promptly after the closing of the operating trust merger. No interest will be paid on any cash consideration payable to you. In addition, we or the paying agent will deduct any applicable withholding taxes from such cash consideration.

Q:    Do I need to return my certificates for the Class A-1 common units?

A:
If you received a certificate representing your Class A-1 common units, you must deliver such certificate, regardless of whether you elect to receive the cash consideration. If you did not receive such a certificate, you are not required to deliver any certificate. If you received a certificate representing your Class A-1 common units and such certificate has been lost, stolen or destroyed, you are required to make an affidavit of the fact that such certificate has been lost, stolen or destroyed in order to receive the Series O preferred units or the cash consideration for your Class A-1 common units. In order to receive the cash consideration for all or part of your Class A-1 common units, you must also timely and properly complete, execute and return the election form and all necessary attachments, including the Substitute Form W-9 (located in Box 2 on the front of the election form) or appropriate Form W-8 (as applicable) and FIRPTA certificate (Attachments 1A or 1B to the election form), to Mellon Investor Services, LLC, on or prior to     •    , 2007, the election deadline. If you elect to revoke your election and would like to receive a new election form, you may contact Mellon Investor Services, LLC at 1-888-213-0891 (Toll free, if within the U.S., Canada or Puerto Rico) or 1-201-680-6674 (Collect, if outside the U.S.).

Q:    Will the Series O preferred units be certificated?

A:
No, we do not plan to issue certificates representing your Series O preferred units. Instead, your ownership of the Series O preferred units will be recorded in our books and records.

Q:    Will my Series O Preferred Units be transferable?

A:
Series O preferred units are transferable subject to restrictions relating to the maintenance of the tax status of the operating trust, restrictions on transfers to holders of non-recourse liabilities, and restrictions imposed by securities laws in accordance with the new declaration of trust. See "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Transfers—After Operating Trust Merger" on page 114.

Q:    Can I elect to redeem my Class A-1 common units prior to the completion of the mergers?

A:
Yes. Subject to certain conditions, you currently have the right to require us to redeem your Class A-1 common units for, at the election of the company (as directed by Parent in its sole discretion in accordance with the merger agreement), either cash or company common shares. See

10


Q:    What if I pledged my Class A-1 common units to my lender?

A:
You should consult with your lender and review the terms of your pledge agreement before you make your election. In addition, you and/or your lender should contact the company using the information in the election form package as there may be additional documents that need to be completed.

Q:    Can I pledge my Series O preferred units as collateral for a loan?

A:
Yes. However, there are a number of very important differences between the Class A-1 common units and the Series O preferred units, and an investment in Series O preferred units involves different risks than an investment in Class A-1 common units. Therefore, a lender that previously accepted Class A-1 common units as collateral for a loan may be unwilling to accept the Series O preferred units as collateral for a loan. If you wish to pledge your Series O preferred units as collateral for a loan, you should consult your lender as to the acceptability of such form of collateral.

Q:    With regard to the election, what rights will my estate have if I die prior to the operating trust merger effective time?

A.
Under our declaration of trust and bylaws, if you die, the executor (or such person performing similar duties) of your estate will assume all of your rights as a unitholder and may exercise all of your rights, including your right to elect to receive Series O preferred units or the cash consideration in exchange for any Class A-1 common units that you may hold. To the extent you have further questions, we recommend that you consult your advisors.

Q:    Will the operating trust own all of its current properties after the completion of the mergers?

A.
After the operating trust merger effective time, Parent will have the right to remove properties from the operating trust. Parent has informed us that it presently intends to cause the operating trust to distribute to the company a portfolio of assets valued at approximately $9.1 billion (based on the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007) following the operating trust merger effective time. Such properties comprised 39% of total assets and 58% of the units that we owned or had an ownership interest in at March 31, 2007, including units under construction. In addition, these properties accounted for approximately 46% of our pro forma revenues and approximately 26% of our pro forma loss from operations for the year ended December 31, 2006, and approximately 39% of our pro forma revenues and approximately 37% of our pro forma loss from operations for the three months ended March 31, 2007. In addition, Parent may change its intentions with respect to such properties and cause other properties to be sold or distributed from time to time. See "Unaudited Pro Forma Condensed Consolidated Financial Statements" on pages F-1 to F-11 for further information.

Q:    Are there any risks I should consider in deciding whether to elect to receive cash or Series O preferred units?

A.
Yes. In the section captioned "Risk Factors," beginning on page 35, we have described a number of important risks that you should consider in deciding whether to elect to receive the cash consideration or Series O preferred units in connection with the operating trust merger.

11


Q:    Will the Series O preferred units be publicly traded or listed?

A:
No. The buyer parties will not list the Series O preferred units on any exchange or include them in any quotation system. See "Risk Factors—Risks Related to the Series O Preferred Units and Our Structure After the Mergers—Series O preferred units do not and will not have a trading market and have restrictions on transferability" on page 37.

Q:    Has the operating trust, the company or the board of trustees of the company taken a position with respect to whether or not I should elect to receive cash or the Series O preferred units?

A.
No. None of the operating trust, the company, in its capacity as our sole trustee, or the board of trustees of the company has made, or is making, any recommendation to our unitholders with regard to the election in connection with the operating trust merger, and none of them has authorized any other person to make such a recommendation. You must make your own investment decision whether to elect to receive the cash consideration or the Series O preferred units in connection with the operating trust merger.

Q:    Are there any differences between the terms of the Class A-1 common units and the Series O preferred units?

A.
Yes. There are a number of very important differences between the Class A-1 common units and the Series O preferred units, as well as our existing declaration of trust and the new declaration of trust that will be adopted pursuant to the operating trust merger, including, among other things, differences related to distributions and allocations of income and loss, redemption, rights on liquidation, capitalization, issuance of additional units, and unitholder voting rights. See "Description of the New Declaration of Trust of Archstone-Smith Operating Trust After the Mergers" on page 105 and "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders" on page 114.

Q:    What will my voting rights be as a Series O preferred unitholder?

A.
The Series O preferred units will not have any voting rights other than certain approval rights regarding such matters as the issuance of additional Series O preferred units (other than pursuant to the terms of the Series Q-1 and Q-2 preferred units), the issuance of new senior or parity units in the operating trust or amendments to the terms of the Series O preferred units, through merger or otherwise, that are, subject to certain limitations, materially adverse to the rights or preferences of the Series O preferred units.

Q:    Who will be managing the operating trust after the mergers?

A.
MergerCo, as the surviving entity of the company merger, will be our sole trustee. We currently anticipate that our current executive officers will remain executive officers following the completion of the mergers. However, because MergerCo and we will be controlled by TS Fund VII and Lehman Brothers, they will indirectly have the power to make decisions on our behalf. See "Archstone-Smith Operating Trust After the Mergers—Business and Management" on page 149. Parent has finalized Mr. Sellers' employment term sheet and is working with Mr. Sellers to put in place a new incentive plan with the focus of retaining our current executive officers. No terms of

Q:    Will I have the right to cause the operating trust to redeem my Series O preferred units if I receive them in the operating trust merger?

A.
Yes. Under the terms of the Series O preferred units, beginning on the fifth anniversary of the operating trust merger, Series O preferred unitholders will have the right to send the operating trust a redemption notice requesting that we redeem some or all of their Series O preferred units at a redemption price of $60.75 per unit, plus any accumulated but unpaid distributions through the redemption date (determined by taking into account the cumulative amount of income allocated to the holders of Series O preferred units), which will be 120 days after a redemption notice is delivered, subject to the limitation that we are not required to redeem more than one-third of the Series O preferred units outstanding immediately following the mergers in any twelve month period. If we receive redemption notices for a number of Series O preferred units in excess of that limit, we will redeem Series O preferred units in the order that we receive the redemption notices, that is, on a "first received, first redeemed basis." In addition, under certain limited circumstances, Series O preferred unitholders will have the right to cause us to redeem all of their Series O preferred units before the fifth anniversary of the operating trust merger. See "Description of the Series O Preferred Units" on page 108 and "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders" on page 114 for additional discussions about such rights and other terms of the Series O preferred units.

Q:    Will the operating trust have the right to redeem any Series O preferred units that I receive in the operating trust merger?

A.
Yes. We will be entitled to redeem all, but not less than all, of the Series O preferred units beginning on the fifth anniversary of the operating trust merger, at a redemption price equal to the stated value of $60.75 per Series O preferred unit, plus accumulated but unpaid distributions though the redemption date (determined without regard to the cumulative amount of income allocated to the holders of Series O preferred units). In the event that we redeem the Series O preferred units, we will be obligated to pay any and all amounts that would be payable under the then existing tax protection agreements, treating the redemption for this purpose as a sale by us of all of our assets (subject to certain limitations). See "Description of the Series O Preferred Units" on page 108 and "Material United States Federal Income Tax Considerations" on page 136.

Q:    Will I receive distributions prior to the operating trust merger?

A.
No. On May 29, 2007, we made a quarterly distribution of $0.4525 per Class A-1 common unit. Under the merger agreement, prior to the company merger effective time, we are not permitted to declare or pay any further regular distributions on the Class A-1 common units, but we may pay distributions necessary for the company to maintain its status as a REIT under the Internal Revenue Code of 1986, as amended, or the "Code," or for the company to otherwise avoid certain corporate-level and excise taxes under the Code (provided that any such distribution will reduce the cash consideration to be paid to our Class A-1 common unitholders in the operating trust merger on a dollar for dollar basis).

13


Q:    Will I continue to receive distributions after the mergers if I receive the cash consideration for all of my Class A-1 common units?

A.
No. If you receive the cash consideration for all of your Class A-1 common units, you will cease to have any interest in us and hence will not receive any distribution from us after the completion of the mergers.

Q:    What are the preferential distribution rights of the Series O preferred units?

A.
With respect to any Series O preferred units that you may own after the mergers, MergerCo, as our sole trustee after the mergers, will determine when and if we will make any distributions to our unitholders. Each Series O preferred unit will bear cumulative preferential distributions payable in cash quarterly at a stated annual rate of 6% times the stated value, or, if less, the cumulative income allocable to holders of Series O preferred units during the period following the operating trust merger. The preferential distribution rate will increase to a stated annual rate of 8% during any period following the incurrence of certain additional indebtedness as a result of which the ratio of "total debt" (as defined in the terms of the Series O preferred units) to "total asset value" (as defined in the terms of the Series O preferred units) exceeds 0.85 to 1.0. Any distributions that are due but unpaid will accumulate and compound quarterly at the applicable stated distribution rate. See "Description of the Series O Preferred Units" on page 108.

14


Q:    Will I start receiving regular quarterly distributions on the Series O preferred units immediately after the mergers? If not, how and when would I be able to receive the accumulated distributions?

A.
Our ability to pay and the right of holders of Series O preferred distributions to receive current distribution payments will depend upon a number of factors, including the amount of our distributable cash flow after payment of debt service, the amount of book income generated by our operations, and the expected impact of the financial covenants in our debt agreements.

15


Q:    How are existing preferred unitholders of the operating trust being treated in the operating trust merger?

A.
At the operating trust merger effective time, other than our Series I preferred units, all of which are held by the company (and which are expected to be held by MergerCo and its affiliates after the company merger), our outstanding Series M preferred unit, each of our Series N-1 convertible redeemable preferred units, which we refer to as "Series N-1 preferred units," and each of our Series N-2 convertible redeemable preferred units, which we refer to as "Series N-2 preferred units," will be converted into the right to receive one Series P preferred unit, one Series Q-1 preferred unit and one Series Q-2 preferred unit, respectively, all of which will be newly issued at the operating trust merger effective time. The terms of the Series P preferred unit, Series Q-1 preferred units and Series Q-2 preferred units will be substantially similar to the terms of the Series M preferred unit, Series N-1 preferred units and Series N-2 preferred units, respectively, with certain changes to the redemption and conversion rights necessary to reflect the fact that they will no longer be redeemable for or convertible into the Class A-1 common units, and certain other changes. See "Comparison of Preferred Unitholders Rights" on page 131.

Q:    How will the Series O preferred units rank compared to other equity interests in the operating trust?

A.
The Series O preferred units will rank, on liquidation and in payment of distributions, on par with our existing Series I preferred units, as well as the Series P preferred unit, the Series Q-1 preferred units and Series Q-2 preferred units to be issued in connection with the operating trust merger as described above under "How are existing preferred unitholders of the operating trust being treated in the operating trust merger?" and senior to Class A-2 common units to be held by MergerCo. See also "Comparison of Preferred Unitholders Rights" on page 131.

Q:    What rights do I have if I oppose the mergers and the consideration that I am being offered in the election?

A:
The merger agreement provides holders of our Class A-1 common units who do not wish to make the election or receive the Series O preferred units with appraisal rights in accordance with the applicable procedures under Maryland law (which term we use to refer to both the Maryland Real Estate Investment Trust statute, or the "Maryland REIT Law," and the Maryland General Corporation Law, or the "MGCL") to seek appraisal of the fair value of their units. The availability and exercise of appraisal rights are conditioned on strict adherence to the applicable provisions of the MGCL. Such appraisal amount could be more than, the same as, or less than the amount a holder of Class A-1 common units would be entitled to receive under the terms of the merger agreement. Any holder of the Class A-1 common units intending to exercise its appraisal rights must, among other things, submit to us a written objection to the operating trust merger within 10 days after we give you notice (as required by Maryland law) that the company has approved the operating trust merger. As a holder of approximately 89.3% of all of our outstanding

16


Q:    Will I recognize taxable gain or loss for federal income tax purposes as a result of the operating trust merger and the election?

A:
The tax consequences of the operating trust merger to you will depend on whether you receive cash, Series O preferred units, or a combination of cash and Series O preferred units in exchange for your Class A-1 common units.

17


Q:    If I am a holder of Series O preferred units, will I be subject to tax on the income and gain of the operating trust?

A:
Yes. As a general matter, if you are a holder of Series O preferred units, following the operating trust merger, you will report on your federal income tax return your allocable share of the operating trust's income, gains, losses, deductions and credits from and after the operating trust merger. As is currently the case with regard to your interest in the operating trust, such items must be included on your federal income tax return without regard to whether the operating trust makes a distribution of cash to you. In this regard, you will be allocated your proportionate share of the operating trust's gain attributable to any assets sold by the operating trust after the date of the operating trust merger, to the extent that gain would have been recognized if the assets of the operating trust were sold for fair market value at the time of the operating trust merger (including income and gain attributable to asset sales undertaken by the operating trust at the direction of the buyer parties in connection with the mergers, if any). Therefore, in those circumstances you would be required to report taxable income for federal income tax purposes in a given year with respect to which you do not receive cash distributions for that year. Distributions of money by the operating trust to you generally will not be taxable unless the amount of the distribution exceeds your adjusted basis in your Series O preferred units. If the IRS were successfully to assert that you are a creditor of the operating trust, you would be required to treat the accrual of distributions with respect to the Series O preferred units as interest, whether or not paid. Neither the operating trust nor the trustee intend to treat you as a lender to the operating trust. For a more detailed description of these tax considerations, see "Material United States Income Tax Consideration—Treatment of Unitholders that Receive Series O Preferred Units" on page 142.

18


Q:    If I am a party to or the beneficiary of a tax protection or other similar agreement, will my tax protection agreement remain in effect following the operating trust merger?

A:
If you receive Series O preferred units for all of your Class A-1 common units, you will continue to have all rights and benefits accorded to you under any applicable tax protection agreement. The buyer parties have informed us that they believe that any tax protection agreement with respect to which you, as a Class A-1 common unitholder, may be a beneficiary or a party (including, in the case of applicable Class A-1 common unitholders, tax protection provisions set forth in an annex to our existing declaration of trust) shall not apply to any gain that is recognized with respect to your Class A-1 common units for which you are electing to receive the cash consideration as a result of your receipt of the cash consideration. Accordingly, if you elect to receive cash consideration, in whole or in part, the buyer parties intend to take the position that you are not entitled, and the buyer parties and we do not intend to pay you, any additional consideration with respect to any federal, state, local or other taxes payable by you in connection with your election to receive cash.


In addition, if you receive Series O preferred units in the operating trust merger and subsequently cause us to redeem your units, you will be required to waive any rights you have under any applicable tax protection agreement with respect to such Series O preferred units that are so redeemed.


Questions and Answers About the Mergers

Q:    When do you expect the mergers to be completed?

A:
We are working toward completing the mergers as quickly as possible, taking into account that closing is not required to occur during the period from August 15, 2007 to October 4, 2007. We currently anticipate that the mergers will be completed on or about October 5, 2007. Completion of the mergers is subject to, and may be delayed by, certain conditions to closing described elsewhere in this prospectus/information statement, including the expiration of the election period as described more fully herein.

Q:    What is the required approval of the mergers by the common unitholders?

A:
Under the merger agreement, both mergers require the approval of the holders of at least a majority of Class A-1 common units and Class A-2 common units, which we refer to as the "Class A-2 common units," all of which are held by the company, voting together as a single class. Class A-1 common units and Class A-2 common units are referred to collectively as the "common units."

Q:    Is my consent required or being sought to complete the mergers?

A:
No. As a holder of approximately 89.3% of all of our outstanding common units, the company's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement. This approval is expected to be effective 20 days after the date of this prospectus/information statement. As a result, unless you own common shares of the company in addition to being our Class A-1 common unitholder, your approval is not required in connection with the mergers or the other transactions contemplated by the merger agreement. You are not being asked to vote on either of the mergers, we are not asking you for a proxy and you are requested not to send a proxy. You do have the right, however, to make an election with respect to the form of consideration that you will receive in connection with the operating trust merger.

Q:    What happens if I also own the company's common shares?

A:
If you own the company's common shares in addition to owning the Class A-1 common units, the company has mailed to you a proxy statement regarding the company merger, the special meeting of the company's shareholders and other important information, including your right to vote on the

19


Q:    Why did I receive a proxy statement when I do not hold any common shares of Archstone?

A:
Under our current declaration of trust, we are required to send to you any written communication, including the proxy statement, that the company sends to its shareholders. Such proxy statement was sent to you for informational purposes only.

Q:
What vote of common shareholders is required to approve the company merger and the other transactions contemplated by the merger agreement?

A:
The approval of the company merger and the other transactions contemplated by the merger agreement requires the affirmative vote of the holders of at least a majority of the outstanding common shares of the company entitled to vote on such proposal. In connection with such required approval, the company has called, and provided notice of, a special meeting of shareholders to be held at 12:00 noon, local time, on Tuesday, August 21, 2007 at The Hyatt Regency Denver Tech Center, The Business Lounge, 11th Floor, 7800 East Tufts Avenue, Denver, Colorado 80237, at which the common shareholders will be asked to approve the company merger and the other transactions contemplated by the merger agreement.

Q:
Can I attend the special meeting?

A:
No. Only the company's common shareholders and holders of Series I preferred shares of the company of record as of the close of business on July 12, 2007, the record date for the special meeting, are entitled to receive notice of and attend the special meeting or any adjournments or postponements of the special meeting. As a result, unless you separately own the company's common shares, you will not be entitled to attend, nor will you be invited to attend, the special meeting or any adjournments or postponements of the special meeting in your capacity as a Class A-1 common unitholder.

Q:
What will common shareholders of the company receive as a result of the company merger?

A:
Holders of the company's common shares at the company merger effective time will receive, for each common share that they own, $60.75 in cash, without interest and less applicable withholdings and taxes, the same cash consideration that our Class A-1 common unitholders are being given the opportunity to elect to receive pursuant to the election. However, the company's common shareholders do not have the right, and will not be given the opportunity, to elect to receive the Series O preferred units. The company's board of trustees has recommended that the common shareholders vote for the approval of the company merger and the other transactions contemplated by the merger agreement.

20


Q:
Will I receive anything in the company merger as a Class A-1 common unitholder?

A:
No. While you will have the opportunity to elect to receive, as a result of the operating trust merger, the same cash consideration per Class A-1 common unit that the company's common shareholders will receive per share, you will not receive any consideration as a result of the company merger.

Q:
Do any of the company's and the operating trust's executive officers and trustees of the company or any other persons have any interest in the mergers or other transactions that is different than mine?

A:
Yes. Our and the company's executive officers and the company's trustees may have interests in the mergers that are different from, or in addition to, yours, including the consideration that they would receive in connection with the company merger with respect to their restricted share units, share options, dividend equivalent units, phantom common shares and, with respect to certain of the executive officers only, performance units. The executive officers also are entitled to certain change of control payments and benefits following the closing of the company merger in certain circumstances. Further, Mr. Sellers has entered into a term sheet with Parent regarding his employment and compensation with MergerCo following the mergers pursuant to which Mr. Sellers will be entitled to receive future compensation after the completion of the mergers. In consideration for Parent entering into the term sheet with Mr. Sellers, Mr. Sellers agreed that the term sheet supersedes, upon and subject to consummation of the mergers, most provisions of his current change in control agreement with us, including his right to receive severance payments upon a voluntary resignation upon or following the consummation of the mergers. See "The Mergers—Interests of Our Trustees and Executive Officers in the Mergers" on page 69 for additional information about possible interests that the company's trustees and our and the company's executive officers may have in the mergers and other transactions that are different from, or in addition to, yours.

Q:
Have any of the company's shareholders already agreed to the approval of the company merger?

A:
No. However, our and the company's executive officers and the company's trustees have informed us that they intend to vote the common shares of the company that they own for the approval of the company merger and the other transactions contemplated by the merger agreement. As of the record date of the special meeting, the company's trustees and its and our executive officers owned an aggregate of approximately 1,462,167 common shares, entitling them to exercise, in the aggregate, approximately 0.7% of the voting power of the company's common shares entitled to vote at the special meeting.


Questions and Answers About General Matters

Q:
What do I need to do now?

A.
Follow the instructions included in the election form package attached as Attachment A to elect the consideration you want to receive in the operating trust merger for your Class A-1 common units. Prior to doing so, we urge you to carefully read this prospectus/information statement and the annexes, attachments and other documents attached hereto or incorporated by reference herein and forming a part hereof. In addition, we strongly urge you to consult your own legal, financial, tax and other advisors for a full understanding of the tax and other consequences of the operating trust merger and the respective risks and benefits of electing to receive the cash consideration or the Series O preferred units.

Q:
Where can I find more information about the operating trust and the company?

A:
We file certain information with the Securities and Exchange Commission, or the "SEC." You may read and copy this information at the SEC's public reference facilities. You may call the SEC at 1-800-SEC-0330 for information about these facilities. This information is also available at the Internet site the SEC maintains at www.sec.gov and on our website at www.archstonesmith.com.

Ownership of the Operating Trust Following the Mergers (page 84)

        Immediately after the consummation of the mergers, Parent and its affiliates will own, directly or indirectly, all of our common units and Series I preferred units to the extent not redeemed. Class A-1 common unitholders who do not elect to receive cash consideration will automatically receive Series O preferred units in the operating trust merger. Holders of the Series M preferred unit, the Series N-1 preferred units and the Series N-2 preferred units will acquire the Series P preferred unit, the Series Q-1 preferred units and the Series Q-2 preferred units, respectively, in connection with the operating trust merger. MergerCo will become the sole trustee of the operating trust following the mergers.


No Fairness Opinion for the Operating Trust Merger (page 66)

        No fairness opinion, appraisal or other determination of a financial advisor or any other third party was requested or obtained by us, the company, as our sole trustee, or the company's board of trustees with respect to the fairness or value of either the cash consideration or the Series O preferred units that the holders of Class A-1 common units may receive in connection with the election and the operating trust merger.


Risks Associated with the Mergers and Investing in the Series O Preferred Units (page 35)

        The consummation of the mergers and investing in the Series O preferred units involve a number of risks and uncertainties, including those that relate to:

22


        For a detailed discussion on these and other risks, see "Risk Factors" beginning on page 35. You should carefully consider such risk factors, together with the other information provided with or contained or incorporated by reference in this prospectus/information statement, in determining whether to elect to receive the cash consideration in lieu of the Series O preferred units in the operating trust merger.


Interests of Our Trustee and Executive Officers in the Mergers (page 69)

        The company is our sole trustee and is responsible for the oversight and management of the operating trust, with the company being governed by its board of trustees. In addition, each of the company's executive officers also serves as our executive officer in the same capacity. As a result, as appropriate in this prospectus/information statement, we sometimes use the terms "our executive officers" and "our officers" to refer to both the company's and the operating trust's executive officers and the terms "our board of trustees" and "our trustees" to refer to the company's board of trustees.

        Our executive officers and board of trustees may be deemed to have interests in the mergers that are in addition to or different from those of our Class A-1 common unitholders and the company's shareholders, including the following:

23


24


        The company and its board of trustees were aware of these interests and considered them among other matters in approving the merger agreement, the mergers and the other transactions contemplated by the merger agreement.

        We currently anticipate that our current executive officers will remain executive officers following the completion of the mergers. Parent has finalized Mr. Sellers' employment term sheet and is working with Mr. Sellers to put in place a new incentive plan with the focus of retaining our current executive officers. No terms of any such plan have yet been determined. We have agreed in principle to the terms of a separation and general release agreement with Mr. Freeman pursuant to which Mr. Freeman has agreed to resign as the company's and our Chief Operating Officer effective December 31, 2007, but will continue to be employed through December 31, 2008. During the term of Mr. Freeman's continued employment, he will continue to be paid an annual base salary of $450,000. See "The Mergers—Interests of Our Trustees and Executive Officers in the Mergers" on page 69.


Material United States Federal Income Tax Considerations (page 136)

        In general, for federal income tax purposes: (1) you will recognize gain or loss if you receive cash in exchange for some or all of your Class A-1 common units; and (2) it is intended that you should not recognize gain or loss as a result of the operating trust merger itself if you receive only Series O preferred units for your Class A-1 common units in the operating trust (except for any gain resulting from any decrease in your share of the operating trust's liabilities if that decrease exceeds your adjusted tax basis in the Series O preferred units you receive in the operating trust merger), although there cannot be any assurance that the IRS might not successfully assert otherwise. Even if you do not recognize gain or loss as the result of the operating trust merger itself, if you elect to receive Series O preferred units in exchange for your Class A-1 common units, you will be allocated your proportionate share of the operating trust's gain attributable to any assets sold by the operating trust after the date of the operating trust merger, to the extent that gain would have been recognized if the assets of the operating trust were sold for fair market value at the time of the operating trust merger (including income and gain attributable to asset sales undertaken by the operating trust at the direction of the buyer parties in connection with the mergers, if any), but you will not receive any cash distributions with respect to such gain. In addition, regardless of whether you receive Series O preferred units in consideration for your Class A-1 common units or receive cash, you will be allocated your proportionate share of the operating trust's taxable income and gain for the period ending with the date of the operating trust merger, which would include any income or gain recognized as a result of any transactions undertaken by the operating trust at the request of the buyer parties in contemplation of the mergers. You will have to report any such income even though you will not receive any additional cash distributions from the operating trust attributable to such income. Because the tax consequences to you of the operating trust merger will depend on your particular factual circumstances and are uncertain in some material respects, you should consult your own tax advisor in order to obtain a full understanding of the tax consequences to you of the operating trust merger.

25



No Solicitation of Transactions (page 95)

        The merger agreement contains restrictions on our ability to solicit or engage in discussions or negotiations with a third party regarding specified transactions involving us or our subsidiaries. Notwithstanding these restrictions, under certain circumstances and subject to certain conditions, the company's board of trustees may respond to an unsolicited written acquisition proposal or terminate the merger agreement and enter into an acquisition agreement with respect to a superior proposal. Upon entering into an agreement for a transaction that constitutes a superior proposal, the company will be obligated to pay a termination fee to Parent as described below under "—Termination Fee and Expenses."


Conditions to the Mergers (page 99)

        Completion of the mergers is subject to the satisfaction or waiver of a number of conditions, including, among others:

26


        As a holder of approximately 89.3% of all of our outstanding common units, the company's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement. This approval is expected to be effective 20 days after the date of this prospectus/information statement.


Termination of the Merger Agreement (page 101)

        The merger agreement may be terminated and the mergers may be abandoned at any time prior to the operating trust merger effective time, as follows:

27



Termination Fee and Expenses (page 103)

        The company has agreed to pay Parent the termination fee of $235.0 million or reimburse Parent up to $10.0 million for Parent's reasonable transaction expenses under certain circumstances. Parent has also agreed to reimburse the company for its reasonable transaction expenses up to $10.0 million in certain situations.

        The company has agreed to pay Parent the termination fee of $235.0 million if the merger agreement is terminated under the following circumstances:

28



        The company also has agreed to pay Parent the termination fee of $235.0 million, less any reimbursable transaction expenses previously paid to Parent, under the following circumstances:

        The merger agreement also provides that if either party terminates the merger agreement because of the other party's material breach of the merger agreement which would result in the failure of a condition being satisfied by December 31, 2007, the breaching party must reimburse the non-breaching party for its reasonable transaction expenses up to a limit of $10.0 million within three business days of the termination date.

        The company has agreed that if the company fails to pay the termination fee or any termination expenses when due, or Parent fails to pay any termination expenses when due, the company or Parent, as the case may be, will reimburse the other party for all reasonable costs and expenses actually

29


incurred or accrued by such party in connection with the collection under and enforcement of relevant provisions of the merger agreement.


Financing (page 67)

        In connection with the mergers, Parent will cause approximately $15.4 billion in the aggregate to be paid to the company's shareholders (assuming that Parent elects to cause the company to redeem all outstanding Series I preferred shares for the cash consideration in accordance with the terms of the Series I preferred shares), the holders of units of the operating trust (assuming that all of the Class A-1 common unitholders elect to receive the cash consideration in full for all of their Class A-1 common units) and the holders of the company's outstanding share options, restricted share units, dividend equivalent units, phantom common shares, performance units, and share appreciation rights. The merger agreement does not contain a financing condition.

        Parent has obtained the equity and debt financing commitments described below and is obligated under the merger agreement to use its reasonable best efforts to negotiate definitive agreements with respect to the debt financing commitment and to otherwise arrange its debt financing on the terms and conditions described in the debt commitment letter and to satisfy all conditions of the buyer parties in such definitive agreements. If the debt financing under the debt commitment becomes unavailable, Parent is obligated to use its reasonable best efforts to otherwise obtain debt financing in connection with the transactions contemplated by the merger agreement.

        In connection with the execution and delivery of the merger agreement, Parent obtained an equity commitment letter from TS Fund VII to provide Parent with equity financing in an aggregate amount of up to $250.0 million and from Lehman Brothers, Real Estate Private Equity Inc. and Banc of America Strategic Ventures, Inc. to provide Parent with equity financing in an aggregate amount of up to $4.85 billion. Parent also obtained a debt commitment letter from Lehman Commercial Paper Inc. and Banc of America Strategic Ventures, Inc. and its affiliates, which we refer to as "lenders," pursuant to which the lenders have committed to provide Parent with financing in an aggregate amount of up to $17.1 billion. The debt commitment letter terminates on December 31, 2007, unless extended in accordance with its terms and is conditioned on the completion of the mergers and other customary conditions. The lenders have the right to terminate the debt commitment letter under certain circumstances, including if the buyer parties are entitled to terminate the merger agreement due to a breach of certain representations and warranties by the company or a material adverse effect with respect to the company.


Guarantee and Remedies (page 68)

        In connection with the merger agreement, Lehman Brothers and TS Fund VII, which we refer to collectively as the "guarantors," have agreed to unconditionally and irrevocably guarantee the payment obligations of the buyer parties and any obligations to pay losses or damages under the merger agreement in an amount up to an aggregate of $1.5 billion, consisting of a $1.25 billion guarantee from Lehman Brothers and a $250.0 million guarantee from TS Fund VII. Each guarantee will terminate on the earliest of (a) the closing of the mergers and payment of all obligations due by the buyer parties under the merger agreement at such time, (b) termination of the merger agreement by mutual written consent or under circumstances in which the buyer parties would not be obligated to make any payments and (c) one year following a termination under circumstances in which the buyer parties are obligated to make payments (except as to payments for which a claim has been made under the applicable guarantee).

        The company cannot seek specific performance to require the buyer parties to complete the mergers, and the company's exclusive remedy for the failure of the buyer parties to complete the mergers is to seek to recover damages or losses incurred by the company up to an aggregate amount of $1.5 billion, as supported by the guarantees of TS Fund VII and Lehman Brothers described above.

Selected Unaudited Pro Forma Financial Data of Archstone-Smith Operating Trust

        The accompanying unaudited selected pro forma financial data sets forth the historical financial information of the operating trust and Operating Trust MergerSub as a consolidated entity, giving effect to the operating trust merger as if it had occurred (a) on March 31, 2007 with respect to the unaudited pro forma condensed consolidated balance sheet data and (b) on January 1, 2006 with respect to the unaudited pro forma condensed consolidated statements of operations data for the three months ended March 31, 2007 and year ended December 31, 2006. For the purposes of the following data, we have assumed that all of our outstanding A-1 common units will be exchanged for the Series O preferred units in connection with the operating trust merger. In addition to the operating trust merger, the accompanying unaudited pro forma selected financial data also presents the pro forma impact of the distribution of certain assets that Parent has informed us it intends to cause the operating trust to make immediately after the operating trust merger effective time. The unaudited selected pro forma financial data should be read in conjunction with the historical financial statements of the operating trust and the notes thereto, as set forth in the quarterly report on Form 10-Q for the three months ended March 31, 2007 and the 2006 annual report on Form 10-K for the year ended December 31, 2006, both of which are incorporated by reference into this prospectus/information statement, and the unaudited pro forma condensed consolidated financial statements and the notes thereto. See "Where You Can Find More Information" on page 163 and "Unaudited Pro Forma Condensed Consolidated Financial Statements" beginning on page F-2. The unaudited pro forma condensed consolidated financial data are presented for informational purposes only and are not necessarily indicative of what the actual consolidated financial position or results of operations of the operating trust would have been for the periods presented, nor do they purport to represent the forecasted results of future periods.

Ratio of Earnings to Combined Fixed Charges and Preferred Distributions

Historical Ratio of Earnings to Combined Fixed Charges and Preferred Distributions

        The following table sets forth our ratios of earnings to combined fixed charges and preferred distributions for the periods indicated. For this purpose, "earnings" consist of earnings from operations plus fixed charges other than capitalized interest and "fixed charges" consist of interest on borrowed funds (including capitalized interest and amortization of debt discount and issuance costs) and preferred distributions.

For the three months ended March 31, 2007 and year ended December 31, 2006, on a pro forma basis, the aggregate amount of combined fixed charges and preferred distributions would have exceeded our earnings by approximately $134.1 million and $550.6 million, respectively. The deficiencies of the pro forma ratios of earnings to combined fixed charges and preferred distributions for these periods are primarily due to the significantly increased interest expense, depreciation expense and to the pro forma accrual of distributions on the Series O preferred units, on a pro forma basis, after giving effect to the operating trust merger as if it had occurred on January 1, 2006. For the purpose of this table, we have assumed that all of our outstanding A-1 common units will be exchanged for the Series O preferred units in connection with the operating trust merger.


Regulatory Approvals (page 77)

        EC No. 139/2004 requires notification to and prior approval by the European Commission of mergers or acquisitions involving parties with aggregate worldwide sales and individual European Union sales exceeding specified thresholds. We and the buyer parties have determined that the mergers are subject to filing requirements under EC No. 139/2004. Once a complete notification is filed, the European Commission has an initial (Phase I) period of 25 working days from the day following the date of notification, which period may be extended under certain circumstances, in which to consider whether the mergers would significantly impede effective competition in the common market or a substantial part of it, in particular as a result of the creating or strengthening of a dominant position. By the end of this Phase I period, the European Commission must issue a decision either clearing the mergers or opening an in-depth Phase II investigation. A Phase II investigation can extend the investigation period up to an additional 125 working days.

        In addition, we are required to make filings under the securities, or "blue sky," laws of certain states with regard to the election being afforded to holders of Class A-1 common units to receive cash consideration or Series O preferred units, or a combination thereof, in exchange for their Class A-1 common units. In certain states we will not be able to proceed with the mergers unless the operating trust has obtained the confirmation of the availability of an applicable exemption and/or qualification of the issuance of the Series O preferred units. In other states, approval of the filing and the contents of this prospectus/information statement may be required before we can offer the election or issue Series O preferred units to holders of Class A-1 common units who are residents of those states. Accordingly, we will not be able to consummate the mergers until any necessary approvals under applicable state securities laws are obtained.

        Other than EC No. 139/2004, the Form S-4 of which this prospectus/information statement forms a part becoming effective, our obtaining any necessary approvals under state securities or "blue sky" laws and the filing of articles of merger by each of the company and the operating trust with the SDAT, we are unaware of any other material federal, state or foreign regulatory requirements or approvals that may be required to consummate the mergers.

Litigation Relating to the Mergers (page 78)

        On May 30, 2007, two separate purported shareholder class action lawsuits related to the merger agreement and the transactions contemplated thereby were filed naming the company and each of the company's trustees as defendants. One of these lawsuits, Seymour Schiff v. James A. Cardwell, et al. (Case No. 2007cv1135), was filed in the United States District Court for the District of Colorado. The other, Mortimer J. Cohen v. Archstone-Smith Trust, et al. (Case No. 2007cv1060), was filed in the District Court, County of Arapahoe, Colorado. On May 31, 2007, two additional purported shareholder class action lawsuits related to the merger agreement and the transactions contemplated thereby were filed in the District Court, County of Arapahoe Colorado. The first, Howard Lasker v. R. Scot Sellers, et al. (Case No. 2007cv1073), names the company, each of the company's trustees and one of the company's senior officers as defendants. The second, Steamship Trade Association/International Longshoremen's Association Pension Fund v. Archstone-Smith Trust, et al. (Case No. 2007cv1070) names the company, each of the company's trustees, Tishman Speyer and Lehman Brothers as defendants. On June 11, 2007, an additional purported shareholder class action lawsuit related to the merger agreement, Doris Staehr v. Archstone-Smith Trust, et al (Case No. 2007cv1081), was filed in the District Court, County of Arapahoe Colorado, naming the company and each of the company's trustees as defendants. All five lawsuits allege, among other things, that the company's trustees violated their fiduciary duties to the company's shareholders in approving the mergers.

        All five lawsuits purport to be brought as class actions and seek to enjoin the completion of the mergers and the related transactions. In addition, among other things, the complaints in each of Seymour Schiff v. James A. Cardwell, et al. and Howard Lasker v. R. Scot Sellers, et al. seek compensation for all losses and damages allegedly suffered by class members as a result of the transactions (the Lasker complaint requests compensatory damages and/or rescission of the company merger) and the complaints in Mortimer J. Cohen v. Archstone-Smith Trust, et al. and Doris Staehr v. Archstone-Smith Trustseek an order directing the company to obtain a transaction which is in the best interests of the company's shareholders.

        On June 21, 2007, the District Court, County of Arapahoe Colorado entered an order consolidating the Lasker, Steamship Trade Association/International Longshoremen's Association Pension Fund and Staehr actions into the Cohen action, under the caption In re Archstone-Smith Trust Shareholder Litigation. We intend to vigorously defend these actions.


Deregistration of Class A-1 Common Units (page 78)

        If the operating trust merger is completed, our Class A-1 common units will be deregistered under the Securities Exchange Act of 1934, as amended, which we refer to as the "Exchange Act."

RISK FACTORS

        An investment in the Series O preferred units involves a number of risks and uncertainties. You should carefully consider the following material risk factors, together with the other information contained or incorporated by reference in this prospectus/information statement, in determining whether to elect to receive the cash consideration in lieu of the Series O preferred units in the operating trust merger.


Risks Related to the Series O Preferred Units and Our Structure After the Mergers

        After the closing of the operating trust merger, our Class A-1 common unitholders who receive Series O preferred units will remain unitholders of the operating trust, subject to the terms of a new declaration of trust that will become effective at the operating trust merger effective time, which are materially different from, and may be less favorable than, the rights they have as holders of the Class A-1 common units under our existing declaration of trust. You should carefully review the form of the new declaration of trust (which includes the terms of, and will govern, the Series O preferred units), which is attached to this prospectus/information statement as Annex B. In addition, you should also review the description of the new declaration of trust and the bylaws and your rights as a Series O preferred unitholder thereunder in the sections captioned "Description of the New Declaration of Archstone-Smith Operating Trust After the Mergers" on page 105, "Description of the Series O Preferred Units" on page 108 and "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders" on page 114.

        Current distributions on the Series O preferred units will be limited by the amount of available cash, the amount of net income allocated to holders of Series O preferred units and the terms of any debt or loan agreements to which the buyer parties or we are parties or their or our assets are subject. In addition, while MergerCo presently intends to be organized as a REIT, it may not continue to be organized as a REIT and, therefore, will not need regular distributions from us to meet the REIT distribution requirements. No assurance can be given as to the timing or amount of cash distributions, if any, to be made in respect of the Series O preferred units. Initially, we do not expect that our operations will generate distributable cash flow or book income due to interest expense and depreciation deductions, among other things, and, accordingly, we do not expect to be able to pay regular quarterly distributions on the Series O preferred units, and it is possible that no cash distributions will be made in respect of the Series O preferred units at all. Cumulative distributions in respect of each Series O preferred unit, if any, will not in any event exceed an amount equal to 6% per annum (subject to increase to 8% under certain circumstances) of the $60.75 stated value of each Series O preferred unit, such distributions to be compounded quarterly to the extent unpaid.

        If all accumulated and unpaid distributions (determined without regard to the cumulative amount of income allocable to holders of Series O preferred units as described elsewhere) have been paid or set aside for payment, and if all requests for redemption of Series O preferred units have been fully paid, we will be able to make distributions on our junior units, including the Class A-2 common units held by MergerCo, even if the cumulative amount of distributions paid on the Series O preferred units is less than the full amount that has accrued at the stated distribution rate of 6%, subject to certain restrictions.

        In connection with the merger agreement, Parent obtained commitments for debt financing for the purpose of the mergers, funding reserves, refinancing a portion of the company's existing debt, and for other costs and expenses related to the mergers. It is anticipated that such debt financing will impose limitations on distributions. In addition, Series O preferred unitholders will not participate in any

35



profits of the operating trust or gains recognized by the operating trust in excess of such amounts. See "Description of the New Declaration of Trust of Archstone-Smith Operating Trust After the Mergers" on page 105, "Description of the Series O Preferred Units" on page 108 and "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders" on page 114. Neither Parent nor MergerCo has guaranteed or has any liability to the holders of Series O preferred units for the payments provided with respect thereto.

        Under the terms of the Series O preferred units, commencing on the fifth anniversary of the operating trust merger, each holder of Series O preferred units has the right to require us to redeem some or all of such holder's Series O preferred units at a cash price equal to the liquidation preference of $60.75 per Series O preferred unit plus any accrued and unpaid distributions, through the redemption date (determined by taking into account the cumulative amount of income allocated to the holders of Series O preferred units) subject to a limitation that we are not required to redeem more than one-third of the Series O preferred units outstanding immediately following the mergers in any twelve month period. Separately, at any time prior to the fifth anniversary of the operating trust merger, each holder of Series O preferred units has the right to require us to make such a redemption and pay the redemption price described above plus any amounts payable to such holder under its existing tax protection agreements, treating the redemption for this purpose as a sale by us of all of our assets (subject to certain limitations), if we make any distributions on the common units (or other junior units) at a time when the ratio of total debt (which includes for this purpose the total liquidation preference of the Series O preferred units and any other parity preferred units) to total asset value is greater than 0.85 to 1.0 or, with some exceptions, within 60 days before and in contemplation of incurring new debt that causes the ratio to exceed that level. However, no assurance can be given that we will have sufficient cash or availability of borrowings to pay such redemption price and the related tax protection payments, if any, at such times as the Series O preferred unitholders may exercise their redemption rights, or that the terms of any loan, credit or other similar agreements to which we may then be a party will allow such redemptions or payments to be made. Neither Parent nor MergerCo has guaranteed or has any liability to the holders of Series O preferred units for the payments of the redemption amounts provided for with respect thereto or any tax protection payment required to be made by the operating trust. In addition, if there has not been sufficient net income and appreciation in the value of our properties after the closing of the operating trust merger, the amount of current and unpaid distributions owed on the Series O preferred units at the time of the redemption may not be sufficient to provide a cumulative 6% per annum (or 8% per annum, if applicable) return on the Series O preferred units. See "Description of the New Declaration of Trust of Archstone-Smith Operating Trust After the Mergers" on page 105 and "Description of the Series O Preferred Units—Redemption Rights" on page 110.

        At any time after the fifth anniversary of the operating trust merger, we will have the right to redeem all (but not less than all) of the Series O preferred units for cash equal to the liquidation preference of $60.75 per Series O preferred unit plus all accrued and unpaid distributions through the redemption date (determined without regard to the cumulative amount of income allocated to the holders of Series O preferred units) and any amounts that would be payable under all holders' existing tax protection agreements, without the consent of any Series O preferred unitholder. See "Description of the Series O Preferred Units—Redemption at the Operating Trust's Option" beginning on page 111.

36


        The Series O preferred units are new securities for which there is currently no public or other trading market. The buyer parties will not list the Series O preferred units on a securities exchange, and it is unlikely that any person will make a market in the Series O preferred units, or that an active market for the Series O preferred units will develop, particularly since the terms of the Series O preferred units contain restrictions that are designed to prevent that from occurring.

        The Series O preferred units also will be subject to significant restrictions on transferability. We may also prohibit any transfer of the Series O preferred units by a unitholder that would result in us being treated as an association taxable as a corporation for federal income tax purposes or would result in a termination of the partnership for federal income tax purposes. As a result of these restrictions on transferability, you may not be able to sell your Series O preferred units should a need for immediate liquidity arise (except for your right to have your Series O preferred units redeemed following the fifth anniversary of the operating trust merger, or for a limited period of time following the death of a unitholder or, in the case of a unitholder that is a trust that is includible in the taxable estate of an individual, the death of such individual) and, even if Series O preferred units are sold, the price at which they are sold may be significantly less than their fair market value. See "Description of the New Declaration of Trust of Archstone-Smith Operating Trust After the Mergers on page 105.

        Similar to the existing declaration of trust, the new declaration of trust will not permit unitholders (other than MergerCo and its affiliates), including Series O preferred unitholders, from engaging in the active management and control of our business. Our Series O preferred unitholders generally will not have any voting rights in respect of any matters except in connection with our issuance of additional Series O preferred units (other than pursuant to the terms of the Series Q-1 and Q-2 preferred units), issuance of new units ranking on par with or senior to the Series O preferred units, amendments to the terms of the Series O preferred units, through merger or otherwise, that are materially adverse to the rights or preferences of the Series O preferred units, and amendments of certain other specified provisions of our declaration of trust. These approval requirements are subject to certain exceptions described under "Description of the Series O Preferred Units—Voting Rights" on page 112. Instead, MergerCo will control our management and operations and will determine, without the consent of Series O preferred unitholders, the outcome of transactions, our management policies and business objectives, including potential acquisitions and divestitures of a significant number of our properties and assets or interests in us and the distribution of cash and other property held by us. As a result, you must rely entirely on the ability of MergerCo and its affiliates to conduct and manage our affairs. In addition, Series O preferred unitholders will not have the right to appoint, elect or remove MergerCo or a successor as our sole trustee even if MergerCo may transfer all of its interest, including its rights as our sole trustee, to another person.

        Our Class A-1 common units are currently registered under the Exchange Act. If the operating trust merger is completed, our registration could be terminated upon application of the operating trust to the SEC if our units are not listed on a securities exchange (which they will not be) and there are fewer than 300 holders of record of all operating trust units. The termination of registration of our units under the Exchange Act would substantially reduce the information required to be furnished by

37


the operating trust to holders of its units and to the SEC and would also make certain of the provisions of the Exchange Act, such as the short-swing profit recovery provisions of Section 16(b), the requirement of furnishing a proxy statement in connection with security holders meetings, the related requirement of an annual report to security holders, and the requirements of Rule 13e-3 promulgated under the Exchange Act with respect to going private transactions, no longer applicable.

        As of March 31, 2007, we owned or had an ownership position in 344 communities, representing 86,014 units, including units under construction, concentrated in six key markets in the United States. The buyer parties have informed us that they intend to cause the operating trust to distribute to the company a portfolio of assets valued at approximately $9.1 billion (based on the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007) following the consummation of the operating trust merger. Such properties comprised 39% of total assets and 58% of the units that we owned or had an ownership interest in at March 31, 2007, including units under construction. In addition, these properties accounted for approximately 46% of our pro forma revenues and approximately 26% of our pro forma loss from operations for the year ended December 31, 2006, and approximately 39% of our pro forma revenues and approximately 37% of our pro forma loss from operations for the three months ended March 31, 2007. The Series O preferred unitholders will generally not receive any economic benefits related to such properties. In addition, after the operating trust merger, Parent may change its intentions with respect to such properties and cause other properties to be sold or distributed from time to time.

        TS Fund VII and Lehman Brothers are in the business of owning, developing, operating and managing commercial real estate properties, including residential properties, and making investments in various real estate companies, and are likely to continue to acquire, own, develop, operate and manage real estate properties and generally hold interests in real estate companies and properties that may compete directly and/or indirectly with us and our properties and business. Neither we nor any of the Series O preferred unitholders will have any right in or to such other investments, ventures or activities or to the income or proceeds derived from such investments, ventures and activities, and the pursuit of such investments, ventures and activities, even if in direct and/or indirect competition with our business and properties, will not be deemed wrongful or improper or a breach of any duty existing under the new declaration of trust, at law, in equity or otherwise. TS Fund VII and Lehman Brothers will have no obligation to present any investment opportunities to us, even if such opportunities are of a character which could be taken by us, and they and their affiliates will have the right to take for their own account, or recommend to others, any such opportunities. In addition, TS Fund VII, Lehman Brothers and their affiliates are not under any obligation to conduct their other businesses and investment affairs in our best interests or in the best interests of the Series O preferred unitholders.

        The new declaration of trust will provide that, to the maximum extent permitted by Maryland law, MergerCo, as our sole trustee, and our officers and trustees, and employees or agents, will not be liable to us or any of our unitholders, including the Series O unitholders, for money damages except to the extent that (i) MergerCo actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property or services actually received; or (ii) a judgment or other final adjudication adverse to MergerCo is entered in a proceeding based on a finding in the proceeding that MergerCo's action or failure to act was the result of active and

38


deliberate dishonesty and was material to the cause of action adjudicated in the proceeding. We shall indemnify each officer, employee and agent, to the fullest extent permitted by Maryland law.

        MergerCo is under no obligation to consider the separate interests of our unitholders, including the Series O preferred unitholders (including, without limitation, the tax consequences to such unitholders) in deciding whether to cause us to take (or decline to take) any actions, and MergerCo shall not be liable for monetary damages for losses sustained, liabilities incurred, or benefits not derived by our unitholders in connection with such decisions, subject to the terms of any existing tax protection agreements and the specific tax protection provisions of the Series O preferred units unless MergerCo acted in bad faith and the act or omission was material to the matter giving rise to the loss, liability or benefit not derived.


Risks Related to Financings and Our Indebtedness

        Based on the information provided to us by Parent, it is expected that the level of indebtedness of the operating trust after consummation of the operating trust merger will be significantly greater than the level of our indebtedness prior to the consummation of the operating trust merger. Based on the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007, our "total debt," which is indebtedness plus the aggregate liquidation preference of any then outstanding Series O preferred units and any other preferred units, is expected to be approximately $11.5 billion, including at least approximately $9.8 billion of borrowings as compared to approximately $6.5 billion of debt and preferred units at March 31, 2007. See "Archstone-Smith Operating Trust Pro Forma Condensed Consolidated Financial Statements (Unaudited)" on pages F-1 to F-11.

        Our significant level of leverage following the operating trust merger subjects us to risks normally associated with debt financing, including the following, each of which could have important consequences to holders of Series O preferred units:

39


        All or a portion of our financing arrangements may bear interest at a variable rate, and we may incur additional variable rate indebtedness in the future. Accordingly, increases in interest rates could increase our interest expense, which could adversely affect our results of operations, financial condition and ability to pay distributions or redemption payments to holders of Series O preferred units or other unitholders. An increase in interest expense could also cause us to be in default under our financing arrangements. In the absence of interest rate hedging or swap transactions, increases in the average effective interest rate on our variable rate debt could materially increase future interest expense.

        In addition, it is expected that substantially all of the properties and in some cases our ownership interests in our subsidiaries that we will own immediately after the operating trust merger will be subject to mortgages, pledges or other security interests granted to lenders. If a property or group of properties is mortgaged or our interest in a subsidiary is pledged to secure payment of debt and we were unable to pay the required payments as they become due, the lender or other holder of the mortgage or pledge could proceed against its collateral and foreclose on the property or interest, resulting in a loss of our investment. Even if a loan is nonrecourse, the lender might have the right to recover deficiencies arising from fraud, environmental liabilities or other circumstances. Foreclosure also could create taxable income to a unitholder without producing any cash, thereby reducing the economic benefits to holders of Series O preferred units, to the extent not protected by any tax protection agreement.

        When any of our debt secured by mortgage liens on our properties or pledges of our interests in certain subsidiaries comes due, we are very unlikely to have enough cash to pay the debt. Therefore, we will have to refinance the debt; however, we may not be able to refinance existing debt, which in virtually all cases requires substantial principal payments at maturity and, even if we can refinance, the terms of a refinancing might not be as favorable as the terms of existing debt. If the interest rate on any new debt is higher than the rate on the old debt, our costs will increase or proceeds might be less than the amounts to be refinanced. Our ability to refinance any of this debt and the terms on which we might refinance will depend upon numerous factors, including economic conditions in general and specifically on conditions in the capital markets or on our performance. If principal payments due at maturity cannot be refinanced, extended or paid with proceeds of other capital transactions, cash flow may not be sufficient in all years to repay all maturing debt at the relevant time(s) and the property securing mortgage loans or pledges of our interests in certain subsidiaries securing other existing debt may be foreclosed upon or we may be forced to dispose of properties or interests on disadvantageous terms, which may materially adversely affect the value of your Series O preferred units and your ability to collect payment from us under any existing tax protection agreement in effect at the time.

        Despite our significant leverage following the consummation of the operating trust merger, we may be able to incur substantial additional indebtedness in the future. To the extent new debt is added to our currently anticipated debt levels, the substantial leverage risks described above, and therefore the risks of investing in the Series O preferred units, would increase.

40



Risks Related to the Mergers

        The mergers are currently expected to be consummated on or about October 5, 2007. However, certain events may delay or prevent the consummation of the mergers, including, without limitation, the failure of the company to obtain the requisite approval of its common shareholders and our failure to satisfy other closing conditions to which the mergers are subject. If these events were to occur, the receipt of the cash consideration and/or the Series O preferred units by the Class A-1 common unitholders would be delayed. Further, if these events were to delay the closing past December 31, 2007, either we or the buyer parties may terminate the merger agreement in accordance with its terms.

        Since the announcement of the proposed mergers on May 29, 2007 through the date of this prospectus/information statement, five purported class action lawsuits have been filed by shareholders of the company in Colorado state and federal courts, seeking, among other things, to enjoin the proposed company merger. The plaintiffs assert claims of breach of fiduciary duty against the company's trustees. It is possible that additional lawsuits may be filed against us, the company and/or the buyer parties, asserting similar or different claims. There can be no assurance that we will be successful in the outcome of any of these pending or future lawsuits and any judgments in respect of these lawsuits adverse to us and the buyer parties may adversely affect our ability to consummate, or delay or prevent the consummation of, the mergers.

        If the merger agreement is terminated under certain circumstances, we may be required to pay Parent a $235.0 million termination fee or reimburse Parent up to $10.0 million of transaction expenses, as more fully described under the section entitled "The Merger Agreement—Termination Fee and Expenses." The mergers are subject to customary conditions to closing, including the receipt of the required approval of the company's common shareholders. If any condition to the mergers is not satisfied or, if permissible, waived, the mergers will not be completed. In addition, we and Parent may terminate the merger agreement in certain circumstances. If the mergers are not completed for those or any other reasons, the market price of the company's common shares, and accordingly, the value of the Class A-1 common units, are likely to decrease to the extent that the current market price and value reflect an assumption that the mergers will be completed. We have diverted significant management resources from our normal operations and implementation of our business strategy in an effort to complete the mergers and are subject to restrictions contained in the merger agreement on the conduct of our business that prevent us from engaging in activities that we otherwise would under normal circumstances. If the mergers are not completed, we will have incurred significant costs, for which we will have received little or no benefit, and such costs could have a material adverse effect on our results of operation.

        In the merger agreement, we agreed to pay a termination fee of $235.0 million in specified circumstances, including some circumstances where a third party acquires or seeks to acquire us, as more fully described under the section entitled "The Merger Agreement—Termination Fee and Expenses" on page 103. These provisions could discourage other parties from trying to acquire us, even if those parties might be willing to offer a higher amount or different form of consideration to the

41


Class A-1 common unitholders than the buyer parties are offering in connection with the merger agreement.

        In considering the election and reviewing and understanding the merger agreement, you should be aware that certain of our executive officers and the company's trustees may have material financial interests in the mergers that are different from, or in addition to, the interests of Class A-1 common unitholders generally. Such interests, which are more fully described under the section entitled "The Mergers—Interests of Our Executive Officers and Trustees in the Mergers" on page 69 include the receipt of severance payments and acceleration of their equity awards in connection with the mergers, as well as, in the case of Mr. R. Scot Sellers, our Chief Executive Officer and the company's chairman of the board of trustees, entering into a binding employment term sheet with Parent regarding his future employment with MergerCo after the consummation of the mergers.


Risks Related to Our Business and Real Estate Investments

        A taxable sale of any of the properties acquired in our acquisition of Charles E. Smith Residential, or the "Smith company," prior to January 1, 2022, could result in increased costs to us in light of the tax-related obligations made to the former holders of partnership units in the operating partnership of the Smith company. We have similar restrictions on the disposition of other properties, including the properties acquired from Oakwood Worldwide in 2005. The restrictions related to the Oakwood properties last until the earlier of (a) such time as the contributing partners have sold, redeemed or otherwise disposed of 99% of their Class A-1 common units (or Series O preferred units they receive in exchange therefor in connection with the operating trust merger) in a taxable event and (b) the later to occur of (x) 10 years from the closing of the contribution of such properties and (y) the last to die of Howard Ruby and Ed Broida. Mr. Broida died in 2006. We also have similar restrictions with respect to other properties that we have acquired.

        Our success will depend on our ability to attract and retain the services of executive officers, senior officers and company managers. There is substantial competition for qualified personnel in the real estate industry and the loss of several of our key personnel could have an adverse effect on us. Even though Parent and Mr. Sellers have entered into a binding term sheet regarding Mr. Sellers' employment with MergerCo following the closing of the mergers, there can be no assurance that he will remain employed with MergerCo or its affiliates after the consummation of the mergers. Additionally, there can be no assurance that the entities surviving the mergers will be able to enter into agreements with, or retain, our other executive officers or other senior managers and other employees. The failure to retain employees could result in higher operating expenses and disrupt the management of our business or the operation of our properties and could have a material adverse effect on our financial condition, results of operations, cash flow and ability to make distributions.

        In addition to secured and unsecured mortgages and other financings, in the past, we have relied significantly on public equity and unsecured debt capital to fund our operations, acquisitions, development and other business activities and cash needs. Because MergerCo, as Archstone's successor,

42


will not be publicly traded, we may not be able to access the public equity or debt markets to raise capital and may have to rely on alternative financing sources to fund our financing and cash needs even if the terms of public equity and debt capital markets were more attractive than the terms of such alternative financing sources. These alternative sources of financing may be more costly to us and adversely affect our results of operations, cash flow and ability to make distributions.

        Periodically, we receive alerts from government agencies that apartment communities could be the target of both domestic and foreign terrorism. Although we currently have insurance coverage for losses incurred in connection with terrorist-related activities, losses could exceed our coverage limits and have a material adverse affect on our operating results.

        Real estate, cash flows and values are affected by a number of factors, including changes in the general economic climate, local, regional or national conditions (such as an oversupply of communities or a reduction in rental demand in a specific area), the quality and philosophy of management, competition from other available properties and the ability to provide adequate property maintenance and insurance and to control operating costs. Real estate cash flows and values are also affected by such factors as government regulations, including zoning, usage and tax laws, caps on rent and rent increases, interest rate levels, the availability of financing, property tax rates, utility expenses, potential liability under environmental and other laws and changes in environmental and other laws. Although we will seek to minimize these risks through our market research and property management capabilities, they cannot be totally eliminated.

        Equity real estate investments are relatively illiquid, which may tend to limit our ability to react promptly to changes in economic or other market conditions. Our ability to dispose of assets in the future will depend on prevailing economic and market conditions. Furthermore, our mezzanine loans to real estate investors may not be recoverable if those investors are unable to monetize the underlying asset at underwritten amounts.

        Our business is heavily regulated and subject to, and we must comply with, increasing local, state and federal statutes, ordinances, rules and regulations concerning zoning, resource protection, environmental impacts, building design, construction, accessibility, certain tenant's rights, rent control, building, health and safety laws, regulations related to the ownership, operation and acquisition of apartments and similar matters. These regulations often provide broad discretion to governmental authorities that regulate these matters, which can result in increases in our operating costs and require us to incur additional capital expenditures. We generally are required to obtain and maintain permits from local authorities that are necessary to operate and renovate our properties. Violations under such permits may, from time-to-time, cause us to incur penalties and costs associated with curing such violations. Our obligation to comply with the laws and regulations under which we operate, and our obligation to ensure that our employees, subcontractors and other agents comply with these laws and regulations, could cause us to incur substantial costs. We may also not be able to pass on increased costs resulting from applicable laws, including tax laws, increases in real estate taxes, income taxes or other governmental requirements, such as the enactment of regulations relating to internal air quality, directly to our residents. Substantial increases in rents, as a result of those increased costs, may affect the ability of a resident to pay rent, causing increased vacancy. In addition to conducting business in the Washington, D.C. metropolitan area, the New York City metropolitan area, the Seattle

43


metropolitan area and the Boston metropolitan area, part of our business is conducted in California, which is one of the most highly regulated and litigious states in the country. Therefore, our potential exposure to losses and expenses due to new laws, regulations or litigation may be greater than other real estate companies with no California presence. Local regulations, including municipal or local ordinances and zoning restrictions, may restrict the use of our properties and may require us to obtain approval from local officials or community standards organizations at any time with respect to renovations we might want to make to any of our properties. These regulations may impose additional operating or renovation costs, which could adversely affect us. In addition, we do not know whether existing requirements will change or whether future requirements will require us to make significant unanticipated expenditures. Under certain laws and regulations, our ability to transfer properties and raise rents may be affected, and we may also be liable for, among other things, the costs of bringing our properties into compliance with the statutory and regulatory requirements. If we fail to comply with various requirements, we might also incur governmental fines or private damage awards. Non-compliance with certain of these laws and regulations may impose liability without regard to fault, and could give rise to actions brought against us by governmental entities and/or third parties who claim to be or have been damaged as a consequence of an apartment not being in compliance with the subject laws and regulations. As part of our due diligence procedures in connection with the acquisition of a property, we conduct an investigation of the property's compliance with known laws and regulatory requirements with which we must comply once we acquire a property, which investigation includes performing a Phase I environmental assessment of the property and a Phase II assessment if recommended in the Phase I report. In addition, the operating trust may continue to own properties that we developed. In developing any such properties, we hired architects and general contractors to design and build these properties, and we relied on them to design and build in accordance with all legal requirements. We cannot, however, give any assurance that our investigations and these assessments have revealed all potential non-compliance issues or related liabilities, or that the properties we developed have been designed and built in accordance with all applicable legal requirements.

        As a general matter, concern about indoor exposure to mold continues as such exposure has been alleged to have a variety of adverse effects on health. As a result, there have been a number of lawsuits in our industry against owners and managers of apartment communities relating to moisture infiltration and resulting mold. We have implemented guidelines and procedures to address moisture infiltration and resulting mold issues if and when they arise. We believe that these measures will minimize the potential for any adverse effect on our residents. The terms of our property and general liability policies after June 30, 2002, may exclude certain mold-related claims. Should an uninsured loss arise against the company, we would be required to use our own funds to resolve the issue, including litigation costs. We can make no assurance that liabilities resulting from moisture infiltration and the presence of or exposure to mold will not have a future material impact on our financial results.

        There are certain types of losses (such as from war) that may be uninsurable or not economically insurable. It is also possible that we could experience losses in excess of the insurance coverage we have in place. Additionally, many of our communities in California are located in the general vicinity of active earthquake fault lines, and our Southeast Florida assets are in coastal locations and subject to hurricanes. Although we maintain insurance to cover most reasonably likely risks, including earthquakes and hurricanes, if an uninsured loss or a loss in excess of insured limits occurs, we could lose both our invested capital in, and anticipated profits from, one or more communities. We may also be required to continue to repay mortgage indebtedness or other obligations related to such communities. The terms of our property and general liability policies after June 30, 2002, may exclude certain mold-related

44


claims. We can make no assurance that liabilities resulting from moisture infiltration and the presence of or exposure to mold will not have a future material impact on our financial results. Should an uninsured loss claim arise against the company, we would be required to use our own funds to resolve the issue, including litigation costs. Any such loss could materially adversely affect our business, financial condition and results of operations.

        Our most significant investment concentrations are in the Washington, D.C. metropolitan area, Southern California, the New York City metropolitan area and the San Francisco Bay Area. We are, therefore, subject to increased exposure from unfavorable economic, real estate, competitive and other conditions and factors specific to markets within these geographic areas, subject to potentially exiting one or more of these markets in conjunction with the distribution of assets after the operating trust merger, as more fully described under "The Mergers—General Description of the Mergers" on page 52.

        There are numerous commercial developers, real estate companies and other owners of real estate that we compete with in seeking land for development, apartment communities for acquisition and disposition and residents for apartment communities. All of our apartment communities are located in developed areas that include other apartment communities. The number of competitive apartment communities in a particular area could have a material adverse effect on our ability to lease units and on the rents charged. In addition, single-family homes and other residential properties provide housing alternatives to residents and potential residents of our apartment communities.


Tax Risks

        If you receive cash in exchange for all of your Class A-1 common units, or if you receive cash in exchange for a portion of your Class A-1 common units, you generally will recognize gain in an amount equal to the excess of (1) your "amount realized" for federal income tax purposes, which equals the amount of cash consideration received (including any amounts of cash withheld), plus your share of our pre-merger liabilities attributable to the units exchanged, over (2) your aggregate adjusted tax basis in those Class A-1 common units exchanged for cash (including basis attributable to your share of our pre-merger liabilities attributable to the units exchanged). If you receive cash in exchange for all or a portion of your Class A-1 common units, you would recognize a loss to the extent that the amount of your basis described in clause (2) above exceeds your amount realized described in clause (1) above. Because your "amount realized" includes the amount of our liabilities allocated to you immediately prior to the operating trust merger, it is possible that the amount of gain you recognize upon the receipt of cash, or even your resulting tax liability, could exceed the amount of cash you actually receive, perhaps by a significant amount.

        The operating trust intends that you should not recognize any gain or loss if you receive only Series O preferred units in the operating trust in exchange for your Class A-1 common units. The proper tax characterization, however, of preferred equity interests in a partnership, such as the Series O preferred units, for federal income tax purposes is complicated and in a number of respects uncertain,

45


and there is a risk that the IRS could assert that holders of Series O preferred units should be treated as creditors of the operating trust. If you were treated as a creditor of the operating trust, the operating trust, MergerCo, and Parent would take the position that you recognize no immediate gain or loss as a result of the receipt of the Series O preferred units, but that gain or loss would be recognized over time under rules applicable to payments made in liquidation of the interest of a retiring partner (generally, as and when distributions are made or deemed made to the extent that they exceed the adjusted basis of the retiring partner in his or her Series O preferred units). There can be no assurance, however, that the IRS would respect such characterization or would not seek to treat you as recognizing gain at the time of the operating trust merger. Neither the operating trust nor MergerCo intends to treat you as a creditor of the operating trust for federal income tax purposes. Even assuming that the Series O preferred units are respected as equity interests in the operating trust for federal income tax purposes, you could recognize gain if, as a result of our post-merger financing and/or dispositions of assets, you experience a reduction in your share of our liabilities and the amount of that reduction exceeds your adjusted tax basis in your Series O preferred units immediately prior to the operating trust merger. For a more detailed discussion of the tax treatment of the operating trust merger and the tax treatment of holders of Series O preferred units following the operating trust merger, see "Material United States Federal Income Tax Considerations" beginning on page 136.

        None of the operating trust, the company, Parent or MergerCo, or anyone else, is making any commitment to you that your receipt of Series O preferred units will be effective to permit you to defer all or any part of the taxable gain that you otherwise would have recognized had you elected to receive cash for your Class A-1 common units.

        Because the tax consequences to you of the operating trust merger will depend on your particular factual circumstances and are uncertain in some material respects, you should consult your tax advisor regarding the potential tax consequences to you of the election to receive either cash and/or Series O preferred units in connection with the election.

        Whether you receive Series O preferred units in consideration for your Class A-1 common units or receive cash, you will be allocated your proportionate share of the operating trust's taxable income for the period ending with the date of the operating trust merger (including income and gain attributable to asset sales undertaken by the operating trust at the request of the buyer parties in contemplation of the mergers, if any). You will have to report such income even though you will not receive any additional cash distributions from the operating trust attributable to such income.

        If you receive Series O preferred units in consideration for your Class A-1 common units, you will be allocated your proportionate share of the operating trust's gain attributable to any assets sold by the operating trust after the date of the operating trust merger, to the extent that gain would have been recognized if the assets of the operating trust were sold for fair market value at the time of the operating trust merger (including income and gain attributable to asset sales undertaken by the operating trust at the direction of the buyer parties in connection with the mergers, if any). You will have to report such income even though you will not receive any additional cash distributions from the operating trust attributable to such income. To the extent, however, that gain is recognized with respect to properties that are covered by existing tax protection agreements with certain Class A-1 common unit holders, you will be entitled to indemnification as and to the extent provided in such agreements.

46


        As described above, existing tax protection agreements with certain Class A-1 common unit holders will remain in effect to the extent not waived in connection with the unitholder's election to receive some cash consideration in the operating trust merger. No assurance can be given, however, that the operating trust will have sufficient cash or availability of borrowings to satisfy payment obligations that arise under such agreements in the future, and neither the company, MergerCo or Parent has any obligation with respect to such payments.

        The trustee of the operating trust will not be required to take into account the tax consequences to you in deciding whether to cause the operating trust to undertake specific transactions or make tax elections that could cause you to recognize gain. Consequently, subject to the terms of any applicable tax protection agreements and the terms of the Series O preferred units, some or all of the deferred gain allocable to the Series O preferred units that you receive in connection with the operating trust merger could be triggered at any time, and we cannot make any assurance to you that you will continue to enjoy the benefit of deferring any such gain. For additional information, see "Material United States Federal Income Tax Considerations" beginning on page 136.

        As a general matter, if you have an existing guarantee of indebtedness of the operating trust, such obligation will continue in effect after the operating trust merger unless the debt to which your guarantee applies is repaid or refinanced, in which case you will be entitled only to the rights you have under any applicable tax protection agreement. As a general matter, if you elect to receive Series O preferred units in connection with the operating trust merger, the continuation of your existing guarantee is intended to allow you to avoid the potentially adverse tax consequences that might result from a reduction of your share of liabilities of the operating trust (such as the recognition of currently deferred gain attributable to your negative capital account and at-risk recapture). We cannot offer you any assurances, however, as to whether these arrangements have in the past or will have in the future the intended tax effect. Moreover, unless you are the beneficiary of a tax protection agreement that specifically requires us to maintain such guarantees in place, except as otherwise provided in the new declaration of the trust, we have no obligations to you in connection with our decisions as to the structuring of our financing arrangements following the operating trust merger, including whether to maintain the debt subject to the guarantees in place, to offer you opportunities to enter into new guarantees, or to avoid taking steps that might make it more likely that a lender would require you to pay on your guarantee.

THE MERGERS

General Description of the Mergers

        Under the terms of the merger agreement, affiliates of Parent will acquire the company and the operating trust. To accomplish this, on the closing date of the mergers, the following transactions will occur:

        As a holder of approximately 89.3% of all of our outstanding common units, the company's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement. This approval is expected to be effective 20 days after the date of this prospectus/information statement.


Background of the Mergers

        From time to time over the course of the last several years, the company's senior management team and board of trustees have periodically evaluated the company's strategic plan. As a result of this evaluation process, the company's board of trustees approved, upon the recommendation of members of the company's senior management team, a strategic plan focused on maximizing shareholder value through capital recycling (generally disposing of non-core assets and applying the proceeds to acquisitions of high-end properties in our core markets), continuing and increasing the company's development activity, expanding the company's ownership of apartment properties in international markets, particularly Germany, and maintaining a disciplined balance sheet to enhance the company's financial flexibility in order to maintain adequate access to capital.

        At the same time, from 2005 through the early part of 2007, the real estate industry experienced all time low capitalization rates, creating unprecedented valuation levels for acquisitions of publicly traded real estate companies, fueled in part by a relatively low interest rate environment and the significant increase in capital flow to the real estate sector by institutional and private equity investors.

        In March of 2006, representatives of Lehman Brothers contacted Mr. Sellers and Mr. Mueller to discuss a possible acquisition of the company at an informal initial indication of interest of $60 per share. However, at that time, Lehman Brothers indicated that it was not yet prepared to submit a formal proposal. No further discussions with Lehman Brothers were held at that time. Mr. Sellers advised the company's board of trustees about this discussion, and the company's board determined not to pursue the matter further unless presented with a formal offer.

        During the course of a review of the company's strategic plan, at a regularly scheduled meeting of the company's board of trustees on March 7, 2007, the company's board and senior management team discussed the possibility of pursuing ways to create incremental value for the company's shareholders through potential asset or entity level acquisitions for cash. As a result of these discussions, the company's board of trustees instructed the company's senior management to contact representatives of a large real estate private equity fund, which we refer to as "Company A," to discuss the possibility of jointly pursuing a cash acquisition of another publicly-traded multi-family REIT. It was determined that

52



the other publicly-traded multi-family REIT was not interested in pursuing a sale transaction, however, Company A requested a meeting with Mr. Sellers and indicated that Company A had conducted a review of publicly available information on publicly traded multifamily companies and that, after such review, Company A was interested in discussing a potential acquisition of the company.

        Also in early April of 2007, the Chief Executive Officer of a publicly-traded REIT, which we refer to as "Company B," contacted Mr. Sellers to indicate that Company B would like to discuss a potential combination with the company.

        On April 12, 2007, Mr. Sellers met with the senior officer of Company A. After a discussion regarding the company's publicly available information, the officer of Company A indicated that Company A would further review publicly available information regarding the company with a view toward considering making a proposal to acquire the company. Mr. Sellers indicated that the company's board of trustees would evaluate any definitive offer.

        On April 13, 2007, Mr. Sellers responded to an invitation to meet with the Chief Executive Officer and the President of Company B. At this meeting, the representatives of Company B indicated that, while they were attracted to the company's portfolio and the company's operating platform, at that time, it would be difficult for Company B to engage in a transaction with us because the trading multiple for our shares was higher than the trading multiple for the shares of Company B. Nevertheless, they said that they would continue to evaluate the possibility of a potential transaction, and would contact Mr. Sellers later to discuss the matter further.

        During the week of April 16, 2007, Mark Walsh, Managing Director and Head of Global Real Estate at Lehman Brothers, contacted Mr. Sellers to inform him that Lehman Brothers and Tishman Speyer were interested in pursuing a potential acquisition of the company. Mr. Walsh requested a meeting with Mr. Sellers in late April 2007 and indicated that Lehman Brothers and Tishman Speyer would conduct a due diligence review of the company based upon publicly available information prior to that time. Mr. Sellers indicated that the company's board of trustees would evaluate any definitive offer.

        Between April 16 and April 23, 2007, Mr. Mueller had several discussions with representatives of Company A to answer due diligence questions based solely on publicly available information. On April 26, 2007, the senior officer of Company A informed Mr. Sellers that Company A would be in a position to submit a non-binding, written indication of interest to acquire the company by Monday, April 30.

        On April 27, 2007, Mr. Sellers and Mr. Mueller met with Mr. Walsh and David Lazarus, a Managing Director, of Lehman Brothers and Messrs. Robert Speyer, Paul Galiano and Steven Wechsler, Senior Managing Directors of Tishman Speyer. At the meeting, the representatives of Tishman Speyer and Lehman Brothers expressed an interest in acquiring the company based upon its premier assets and strong operating and development platform. They indicated to Mr. Sellers that they would be in a position to submit a non-binding, written indication of interest to acquire the company early the following week.

        On April 27, 2007, members of the company's senior management team contacted representatives of Morgan Stanley, an investment bank that had previously worked with the company and was familiar with the company and the multi-family industry, and requested that Morgan Stanley act as financial advisor to the company in connection with the expected indications of interest, subject to discussion with and approval by the company's board of trustees. Senior management also contacted representatives of Hogan & Hartson LLP and requested that, subject to confirmation with the board of trustees, Hogan & Hartson act as legal counsel to the company and its board of trustees in connection with their consideration of any possible sale transaction of the company. Over the course of April 27, 28 and 29, 2007, Mr. Sellers contacted all members of the company's board of trustees and informed

53



them of the expected indications of interest from Tishman Speyer/Lehman Brothers and Company A, as well as the proposed retention of Morgan Stanley as financial advisor and Hogan & Hartson as legal counsel in connection with the consideration of such potential offers.

        On April 30, 2007, Company A submitted its non-binding indication of interest to the company's board of trustees. The offer indicated that, based upon an extensive review of publicly available information, Company A was prepared to acquire the company for a cash purchase price of $62.50 per common share and common unit of the operating trust. The letter further indicated that the offer was subject to execution of a confidentiality agreement, access to certain non-public information and completion of confirmatory due diligence, which Company A indicated could be completed in one week. Company A indicated that it contemplated obtaining the necessary financing and negotiating and being prepared to execute a definitive merger agreement within that one week period, and that any definitive merger agreement would not be subject to any financing contingency.

        On May 2, 2007, the company's board of trustees held a special meeting to discuss the indication of interest received from Company A. Members of the company's senior management team and representatives of Morgan Stanley and Hogan & Hartson were also in attendance at the meeting. Mr. Sellers outlined the background of the contacts and discussions with Tishman Speyer/Lehman Brothers, Company A and Company B. Mr. Sellers also indicated that it was expected that Tishman Speyer/Lehman Brothers would be submitting their indication of interest later that day. Representatives of Hogan & Hartson then reviewed with the board their duties as trustees generally and in connection with the consideration of a potential sale of the company. In addition, the interests of individual trustees in such a potential transaction (described in the section entitled "—Interests of Our Trust's Trustees and Executive Officers in the Mergers" on page 69 of this prospectus/information statement) were discussed and disclosed to the company's board of trustees. Representatives of Morgan Stanley then made a presentation to the company's board of trustees with respect to its preliminary financial analysis of the company, its views on the current real estate market generally and the multi-family sector in particular and a preliminary evaluation of the terms of Company A's proposal. After discussion among the company's board of trustees, senior management and the company's advisors regarding the presentation and the company's strategic plan, the company's board of trustees determined to convene a special meeting the next day to further consider Company A's proposal and to consider the expected proposal from Tishman Speyer/Lehman Brothers. The company's board of trustees then met without advisors and members of management present.

        On the afternoon of May 2, 2007, Tishman Speyer/Lehman Brothers submitted its non-binding, written indication of interest. The proposal was to acquire the company for a cash purchase price of $64.00 per common share and common unit of the operating trust. The proposal indicated that Tishman Speyer/Lehman had conducted an extensive due diligence review of the company based upon publicly available information, including a detailed market and asset-by-asset analysis as well as informal site visits to a majority of the company's properties. The offer indicated that any potential transaction would not be subject to any financing contingency, but that the proposal was subject to completing due diligence and negotiation and execution of a definitive merger agreement, which the proposal indicated could be completed within three weeks. The proposal also requested the ability to negotiate on an exclusive basis, subject to an understanding that any definitive agreement would contain customary fiduciary out provisions and a termination fee consistent with other transactions negotiated on an exclusive basis. The proposal did not request or require the continued employment of Mr. Sellers or other members of management following the closing of a potential transaction.

        On May 3, 2007, the company's board of trustees held a special meeting to continue discussions regarding Company A's proposal and to discuss the proposal of Tishman Speyer/Lehman Brothers and other potential strategic alternatives. Representatives from Morgan Stanley discussed with the company's board its preliminary evaluation of the financial terms of the Tishman Speyer/Lehman Brothers proposal. The company's board of trustees, after consulting with members of the company's

senior management and representatives of Morgan Stanley and Hogan & Hartson, then discussed the two offers, other alternatives available to the company (including seeking other potential purchasers of the company or other alternatives to a potential sale transaction, including pursuing the company's existing strategy as an independent company), the valuation of the company and the merits and risks associated with the continued implementation of the company's strategic plan. The company's board of trustees, after discussions and consultation with senior management and the company's financial and legal advisors, determined that Tishman Speyer/Lehman Brothers and Company A would each have the financial resources necessary to acquire the company and were in a position to move quickly, which was important to the company's board in order to avoid the risks associated with contacting other potential purchasers, including the fact that if the process became publicly known there could be a material disruption to the operations of the company and damage to the company's value, including an adverse impact on the company's relations with employees, and others with whom the company has business relations. The company's board also focused on the limited number of other potential credible bidders given the company's size and the importance of reasonable fiduciary out provisions and a reasonable termination fee under the circumstances. The company's board of trustees then continued to meet briefly without members of management and advisors present. Following the discussion, the company's board of trustees instructed senior management and Morgan Stanley to contact Tishman Speyer/Lehman Brothers and Company A to inform them that, subject to entering into acceptable confidentiality and standstill agreement, they would be provided approximately two weeks in which to conduct their confirmatory due diligence and submit offers regarding a potential acquisition of the company.

        On May 4, representatives of Morgan Stanley contacted representatives of Tishman Speyer/Lehman Brothers and Company A to outline the process proposed by the company's board of trustees, stating that offers, together with a mark-up of a draft merger agreement and financing commitment letters, should be submitted by 5:00 p.m., Eastern Time, on Monday, May 21. Company A indicated that it was willing to participate in such a process, while Tishman Speyer/Lehman Brothers did not confirm its willingness to participate in such process until May 8. On May 9, the company entered into confidentiality and standstill agreements with Tishman Speyer, Lehman Brothers and Company A and began to provide the prospective bidders with due diligence information about the company through an on-line data site.

        On May 8, the company's board of trustees held a special meeting to discuss the status of the discussions with Tishman Speyer/Lehman Brothers and Company A. After an update on the status from representatives of Morgan Stanley, the company's board of trustees discussed, with consultation from representatives of Hogan & Hartson, their duties to the company and operating trust in connection with the proposed transactions and again discussed the interests of individual trustees in any such transaction, including Mr. Sellers' existing change in control agreement and the ownership of operating trust units by Messrs. Kogod, Smith and Gerardi. The company's board also instructed that the company's advisors and senior management team provide regular updates regarding the process to Mr. John C. Schweitzer, the company's lead independent trustee. The company's board of trustees then continued to meet without members of management and advisors present.

        Between May 9 and May 19, members of the company's senior management team and representatives of Morgan Stanley, Hogan & Hartson and Mayer, Brown, Rowe & Maw LLP, our REIT tax counsel that will be providing the REIT tax opinion as a condition to the closing of the mergers, held various meetings and telephone calls with representatives of the potential bidders and their respective advisors to discuss a potential transaction, structure issues and various due diligence matters, including the significant tax protection obligations owed by the company to unitholders of our operating trust and the related economic consequences of potential asset dispositions.

        On May 14, the President of Company B contacted Mr. Sellers by voice mail to indicate that although Company B was continuing to look at a potential combination with the company, the trading

55



multiple for the company's shares continued to be higher than the trading multiple for the shares of Company B and, as such, Company B could only consider a stock-for-stock merger at no or only a modest premium to the company's current trading price. Mr. Sellers attempted on two occasions to discuss the matter further with the President of Company B, but did not receive a return call. There was no further contact with Company B following May 14, and Company B did not express any further interest in pursuing an acquisition of the company following that date.

        Also on May 14, members of the company's senior management team and representatives of Morgan Stanley met with representatives of Tishman Speyer/Lehman Brothers to discuss certain operational and other due diligence matters. At that meeting, Tishman Speyer/Lehman Brothers expressed their interest in acquiring the company and maintaining and building upon its platform and indicated that certain key members of the company's senior management team could be critical to that strategy. Nothing further regarding the continued role of management was discussed at that time.

        On May 15, members of the company's senior management team and representatives of Morgan Stanley met with representatives of Company A to discuss certain operational and other due diligence matters.

        On May 15 and May 16, the company's board of trustees held regular meetings in conjunction with the company's annual meeting of shareholders. At various points during these regular board meetings the company's board was provided updates on the ongoing process from members of the company's senior management team and representatives of Morgan Stanley. Representatives of Morgan Stanley discussed that the debt capital markets had begun to become unsettled, which in their view could cause prospective bidders to have more difficulty making an offer to acquire the company. They also explained that both of the prospective bidders had expressed concern regarding the significant magnitude of the built-in gain associated with certain of the company's properties that are subject to tax protection agreements with operating trust unitholders and the magnitude of the increase in property taxes as a result of the transaction. The company's board also discussed the importance of ensuring that any termination fee payable by the company in the event it receives a superior acquisition proposal that the company's board wishes to pursue be reasonable, and determined to propose a fee equal to 2% of the total equity value of a potential transaction as part of the draft merger agreement to be provided to the bidders. At these meetings, the company's board also ratified and confirmed the retention of Morgan Stanley as its financial advisor and Hogan & Hartson as its legal advisor in connection with the proposed transactions. Mr. Sellers also advised the company's board of the latest contact from Company B. The company's board of trustees determined not to pursue matters further with Company B due to the speculative and preliminary nature of Company B's interest and the amount and form of consideration discussed, including the lack of premium proposed by Company B for the company's shareholders.

        On May 16, a draft merger agreement prepared by Hogan & Hartson after consultation with the company's lead independent director, the company's senior management team and Morgan Stanley, was provided to the prospective bidders. This draft proposed a termination fee of 2% to be paid by the company in the event it were to accept a competing acquisition proposal, and proposed that a prospective buyer would pay a reverse termination fee of $1.0 billion in the event the buyer did not close the acquisition of the company when all closing conditions had been satisfied or waived. The draft also proposed that common unitholders of our operating trust be offered the opportunity to elect to receive the cash consideration to be paid to common shareholders, to continue to hold common units in the operating trust following the operating trust merger, or to receive a preferred unit in the operating trust.

        Also on May 16, representatives of Morgan Stanley had a discussion with representatives of Tishman Speyer/Lehman Brothers regarding their progress in their confirmatory due diligence. During such discussions, Tishman Speyer/Lehman Brothers noted that the deterioration in the debt capital

56



markets and the significant tax protection obligations would likely impact their pricing of a potential acquisition of the company, but noted that they expected to be able to submit their offer on May 21 as requested.

        On May 17, the Executive Compensation Committee of the company's board of trustees, consisting solely of independent members of the company's board of trustees, met to discuss various compensation related matters and the importance of maintaining the company's operations on an ongoing basis and the need to be able to retain employees during any potential transition period during the pendency of a potential transaction and thereafter given the importance of the company's operating platform to the prospective bidders. Mr. Sellers and other members of senior management were invited by the committee to the meeting to answer questions and representatives of Hogan & Hartson were also present at the meeting. At the meeting the committee discussed the effect of a potential sale of the company on the outstanding equity and other incentive awards of the company. The committee also discussed amendments to the change in control agreements of Messrs. Sellers, Mueller and Mark A. Schumacher, the company's Chief Accounting Officer, and Ms. Brower to clarify the intent of the agreements that the company's ceasing to be a publicly traded company would constitute "good reason" as defined in those agreements because a significant portion of their current responsibilities involve matters relating the company's status as a publicly traded company. The committee also discussed the adoption of an amendment to the company's severance policy for employees of the company (other than employees with change in control agreements) to provide such employees with certain payments under certain circumstances if their employment were terminated within 18 months following the consummation of a merger. The committee also discussed the importance of retaining Mr. J. Lindsay Freeman, the company's Chief Operating Officer, at least through December 31, 2007 in order to maintain an orderly transition in the event of a potential transaction. The committee then discussed awarding employees entitled to grants of restricted share units a pro rata portion of the units earned in the prior year through the date of the closing of a potential transaction in order to appropriately compensate employees for the work performed in 2007. The committee did not take any formal action at the meeting.

        Also on May 17, representatives of Company A contacted representatives of Morgan Stanley and indicated their due diligence had made them aware of significant increases in transaction costs, including as a result of the significant impact of the company's existing tax protection agreements with holders of common units in the operating trust on Company A's contemplated plan for selling a substantial number of the company's assets following consummation of an acquisition and the significant impact of real estate taxes and related reassessments. In addition, Company A stated that it had reached a relatively lower valuation of the company's development pipeline and that, due to changes in the debt financial markets, its costs to finance a potential acquisition of the company would be negatively impacted. As a result, Company A indicated that, in the best case, it would be able only to maintain its original indicative price of $62.50 per common share and unit. Company A also stated that it was not willing for operating trust unitholders to retain common equity following an acquisition, because that would negatively affect the anticipated returns that Company A would be able to achieve from an acquisition. On May 18, Company A's financial advisor contacted representatives of Morgan Stanley and indicated that, should Company A submit a subsequent offer, it would be below the original $62.50 proposal.

        On May 18, the company's board of trustees held a special meeting to discuss the ongoing process as well as to receive a report from the Executive Compensation Committee regarding the matters discussed at its meeting on May 17. Members of the company's senior management and representatives of Morgan Stanley and Hogan & Hartson were also in attendance at the meeting. The company's board reviewed the compensation related matters discussed previously by the Executive Compensation Committee and the importance of those matters in maintaining the operating platform on which the prospective bidders had placed significant importance and value. The company's board also instructed

57



senior management and its advisors that no terms of continued employment of members of senior management following the closing of a potential transaction were to be discussed with any potential bidder unless and until a general agreement had been reached on all material terms of a potential merger transaction, including the price per common share and unit. The board of trustees then discussed the proposed terms of the preferred units that operating trust unitholders could elect to receive in lieu of cash consideration or maintaining a common equity interest in the operating trust. Representatives of Morgan Stanley and Hogan & Hartson described potential proposed terms and compared those terms to other recent REIT going private transactions. Messrs. Kogod, Smith and Gerardi then recused themselves from further discussion at the meeting regarding the unit terms. The board continued to discuss those terms and focused on ensuring that the terms of any preferred units to be offered to unitholders in connection with a proposed transaction would include a dividend rate that is comparable to what the capital markets would expect for such a security taking into account the capital structure of the post-acquisition company and the other terms of the preferred units and that the other terms would be similar to precedent transactions.

        On May 19 and 20, representatives of Tishman Speyer/Lehman Brothers indicated to representatives of Morgan Stanley that, due to increased expected transaction costs resulting from their better understanding of the magnitude of the company's tax protection obligations and due to adverse changes in the debt markets, they were uncertain whether any offer that they were to submit would be at a price equal to their initial indication of $64.00 per common share and unit. Tishman Speyer/Lehman Brothers also indicated the need to ensure the continued role of current senior management following the closing of a transaction because of the importance to Tishman Speyer/Lehman Brothers of maintaining the company's operating platform, and the value they were ascribing to that platform. However, no terms or details of any possible employment agreement were discussed at this time, and the requirement of any such agreement prior to executing a definitive merger agreement was not raised by Tishman Speyer/Lehman Brothers.

        Also on May 19, a senior officer of Company A contacted Mr. Sellers to inform him that, due primarily to the costs associated with tax protection and increases in real estate taxes due to reassessments that would result from a potential transaction, and Company A's lower than expected valuation of the company's development pipeline, as well as deterioration of the debt capital markets, Company A would not be submitting an offer to acquire the company.

        On May 21, the company's board of trustees held a special meeting to discuss the ongoing process. Members of the company's senior management and representatives of Morgan Stanley and Hogan & Hartson were also in attendance. Representatives of Morgan Stanley updated the board on Company A's withdrawal from the process. Morgan Stanley also explained that, while Tishman Speyer/Lehman Brothers had indicated that they had obtained the financing necessary to complete the acquisition, they also indicated that the potential tax protection costs, their reduced expectation of possible profits from development projects and the volatility in the debt capital markets would cause them to reduce their price and that they needed an additional day to submit their offer. The board then discussed, with input from senior management and the company's advisors, the possibility of obtaining an increase in the purchase price to the extent common unitholders elect to receive cash in the operating trust merger and thereby reduce the amount of tax protected gain remaining. Representatives of Hogan & Hartson then presented to the board a summary of the material terms of the merger agreement draft provided to the prospective bidders. Following that discussion, representatives of Morgan Stanley reviewed with the board its updated financial analysis of the company and the potential financial impact of the existing tax protection arrangements and other transaction costs, and reiterated the relative uncertainty existing in the debt capital markets and the effect on prices that might be realized in the future for real estate assets and for sales of publicly traded real estate companies.

        Later on May 21, representatives of Tishman Speyer/Lehman Brothers reiterated that they were continuing to address issues related to increased expected transaction costs and adverse changes in the

58



debt capital markets, and indicated that they would be unable to offer a price equal to their initial indication of $64.00 per common share and unit. In addition, Tishman Speyer/Lehman Brothers requested an additional 24 hours to submit their offer, financing commitment letters and a mark-up of the draft merger agreement.

        On May 22, a representative of Morgan Stanley contacted senior representatives of Company A to review the reasons for its withdrawal from the process. During the course of the conversation, the representative of Morgan Stanley asked if there was a price at which Company A would be interested in pursuing the acquisition of the company. The representatives of Company A indicated that, if discussions regarding a potential transaction dropped below $60.00 per share, Morgan Stanley should contact Company A to inform it of such development.

        On May 22, Tishman Speyer/Lehman Brothers submitted a mark-up of the proposed draft of the merger agreement but again requested an additional 24 hours to submit their pricing terms. The mark-up provided, among other things, that future dividends would not be permitted to be paid by the company after the merger agreement was signed, that operating trust unitholders would have the right to elect to receive the cash consideration or a preferred unit in the operating trust, but not to retain their common units in our operating trust, that, instead of a $1.0 billion reverse termination fee in the event of buyer's failure to close, the company would be entitled to seek to recover damages up to a cap of $1.0 billion, and that the termination fee to be payable by the company in connection with certain matters relating to competing acquisition proposals would be 3% of the total equity value of the proposed transaction. At this time, Tishman Speyer/Lehman Brothers also indicated for the first time that they would be unwilling to execute a definitive merger agreement unless they had also negotiated a binding term sheet with Mr. Sellers regarding his continued employment with the company following the closing of a potential transaction.

        On May 23, Tishman Speyer/Lehman Brothers contacted representatives of Morgan Stanley and indicated that they were offering to acquire the company under the terms of their merger agreement mark-up at a price per common share and unit of $60.00. Tishman Speyer/Lehman Brothers indicated that the decrease in the offer price from their preliminary offer was primarily a result of information obtained in their confirmatory due diligence regarding, among other things, the magnitude and scope of the company's tax protection arrangements, the compression in returns that they could expect to realize from the company's development pipeline, and the deterioration of the debt capital markets. In addition Tishman Speyer/Lehman Brothers indicated that they had determined that there were significant transaction costs exclusive of the impact on value associated with the company's tax protection obligations.

        Later on May 23, the company's board of trustees held a special meeting to discuss the proposal from Tishman Speyer/Lehman Brothers. At the outset of the meeting, the company's board was informed about the requirement that Mr. Sellers agree to a binding employment term sheet prior to execution of a definitive merger agreement and the emphasis Tishman Speyer/Lehman Brothers was placing on keeping the company's operating and development platform in place and their view that retaining Mr. Sellers was essential to the price they were willing to pay to acquire the company. The company's board then discussed, and consulted senior management and its advisors regarding, the terms of the Tishman Speyer/Lehman Brothers offer and the current market environment for the company, including the fact that capitalization rates were near all time lows and there were significant risks that they could increase in the near future, which would reduce the company's net asset value. The company's board also discussed the expected moderation of the growth of net operating income expected when compared to the past several years and the continuing pressure on the company's funds from operations due primarily to lower Ameriton gains, more dilution from capital redeployment and higher financing costs, as well as the fact that the transaction costs identified by the potential bidders would continue to be an issue for the foreseeable future. The company's board also considered the fact that those transaction costs would not necessarily be incurred by the company if it continues to pursue

59



its business plan as an independent public company, although over time the company generally would expect to be impacted by increases in assessed values and real estate taxes, and could incur tax protection costs, depending upon its ability to effectively execute tax deferred exchanges in connection with the sale of tax protected assets. After further discussion, the company's board of trustees instructed Morgan Stanley to present a counterproposal, with the price of $62.00 per share and unit and an opportunity for the price to increase based on the number of operating trust units that are tendered for cash, with market terms for the preferred units to be offered to operating trust common unitholders, with a $1.5 billion cap on potential damages payable by Tishman Speyer/Lehman Brothers and a termination fee to be payable by the company in certain circumstances not to exceed 1.5% of the total equity value of the transaction. The board also instructed that Mr. Sellers no longer be involved in any negotiations with Tishman Speyer/Lehman Brothers regarding the merger agreement and that the company's advisors coordinate the merger negotiations with the company's board and Mr. Schweitzer as the lead independent trustee, Mr. Mueller and Ms. Brower. The company's board then met in executive session without the presence of its advisors or members of management present. Representatives of Morgan Stanley later informed Tishman Speyer/Lehman Brothers of the board's position.

        In response to the company's counterproposal, on May 24, Tishman Speyer/Lehman Brothers informed representatives of Morgan Stanley that they had increased their offer to $61.00 per common share and common unit on the terms of the merger agreement mark-up submitted, that they were agreeable to a damages cap of $1.5 billion and would accept a termination fee of 2% of the total equity value of the transaction. Tishman Speyer/Lehman Brothers also indicated that they would not consider the proposed mechanism to increase the purchase price based upon the number of unitholders of the operating trust who elect to receive cash. They proposed that the preferred units to be offered to operating trust unitholders would have a coupon of 6% per annum, which Morgan Stanley advised the board was a coupon that it considered to be within a range of market rates in light of the circumstances, including, among other things, the post-acquisition capital structure of the operating trust that Morgan Stanley considered to be likely, the other proposed terms of the preferred units and terms of preferred securities in comparable transactions that included a similar preferred security. The company's board then discussed the transaction costs inherent in a deal of this nature or a similar strategic transaction or liquidation scenario, the uncertainties facing the company in the continued implementation of its strategic plan, including the expectation of increasing capitalization rates and possibly increasing interest rates, the risks that these uncertainties placed on the future valuation of the company, the fact that the proposed price represented a significant premium to the current trading price of the company's shares and the risk that the company's shares would not continue to trade at their recent multiples of funds from operations for the foreseeable future as these multiples represented relatively high multiples compared to the historic trading prices of the company's common shares.

        The company's board also discussed issues associated with Mr. Sellers' employment, including the fact that he would not engage in any negotiations on behalf of the company and would retain independent counsel to negotiate the terms of his continued employment with Tishman Speyer/Lehman Brothers following a potential transaction. The company's board instructed that Mr. Sellers was not to negotiate his employment terms until the other principal terms of the proposed transaction had been reached and only under the condition that, after the execution of a definitive agreement between the company and Tishman Speyer/Lehman Brothers, any such employment agreement allow him to negotiate with potential competing bidders whom the company's board had concluded had submitted a superior proposal. Members of management, including Mr. Sellers, were then asked to leave the meeting and the board continued to meet in executive session with its advisors present. After extensive further discussion, the company's board of trustees agreed to proceed with the Tishman Speyer/Lehman Brothers offer and authorized Mr. Schweitzer, members of senior management other than Mr. Sellers and the company's advisors to negotiate with Tishman Speyer/Lehman Brothers on substantially the terms described to the board.

60



        Shortly before the close of trading on the New York Stock Exchange on May 24, an industry publication speculated about a potential acquisition of the company by Tishman Speyer/Lehman Brothers. The company's common share price rose approximately 3.6% that day after such publication and approximately 8.0% on May 25 on higher than normal trading volume.

        Later on May 24, Tishman Speyer/Lehman Brothers discussed with representatives of Morgan Stanley that its offer of $61.00 per common share and common unit assumed that the company would not pay its second quarter common share dividend of $0.4525 per share. Tishman Speyer/Lehman Brothers indicated that they were unwilling to pay $61.00 per common share and common unit unless the second quarter dividend was not paid. During the evening of May 24, the company's board of trustees held a special meeting to discuss this issue. After extensive discussion among the company's board of trustees, senior management and financial and legal advisors, the company's board of trustees instructed representatives of Morgan Stanley to inform Tishman Speyer/Lehman Brothers that the board was prepared to accept a price of $60.75 per common share and common unit assuming the payment of the second quarter dividend of $0.4525 per common share as planned and assuming a company termination fee of 1.5% of the total equity value of the transaction. Later that evening, representatives of Morgan Stanley informed Tishman Speyer/Lehman Brothers of this proposal, and Tishman Speyer/Lehman Brothers agreed to such terms.

        During the period from May 24 through May 28, Mr. Schweitzer, representatives of the company's management (other than Mr. Sellers), Tishman Speyer/Lehman Brothers, Morgan Stanley, Hogan & Hartson, Wachtell, Lipton, Rosen & Katz, legal counsel to Tishman Speyer and Weil, Gotshal & Manges LLP, legal counsel to Lehman Brothers, negotiated the terms of the merger agreement, the terms of the preferred units to be offered to common unitholders in the operating trust, the terms of the equity and debt financing commitments of Tishman Speyer/Lehman Brothers and the terms of the payment guarantees of Tishman Speyer and Lehman Brothers. Also during this period, Mr. Sellers and his legal counsel negotiated the terms of his employment term sheet with Tishman Speyer/Lehman Brothers.

        On May 28, the company's board was provided with a copy of the near final draft merger agreement that had been negotiated with Tishman Speyer/Lehman Brothers, a detailed summary of the merger agreement and the terms of the preferred units to be offered to operating trust common unitholders and various other materials.

        On the evening of May 28, the Executive Compensation Committee of the company's board of trustees met to address the matters presented to the committee at its May 17 meeting—namely, clarifying amendments to certain change in control agreements, the adoption of an amendment to the company's severance plan, the payment of an additional $1,000,000 to Mr. Freeman if he continued his employment with the company through December 31, 2007 and the payment of the cash value of a pro rata percentage of restricted share unit grants to employees otherwise entitled to such grants based upon grants related to 2006 and the payment of certain other cash incentives to certain non-executive officer employees of the company in Germany in order to ensure an orderly transition and the continued operation of the company's business after the announcement of the proposed transaction. Representatives of Hogan & Hartson were present at the meeting and reviewed with the committee its duties. After further discussion, the committee adopted and approved these actions and recommended that the actions related to the change in control agreements and the severance plan be adopted and approved by the company's board of trustees.

61


        The company's board of trustees then convened a special meeting to consider the proposed merger agreement with Tishman Speyer/Lehman Brothers. Members of the company's senior management team and representatives of Morgan Stanley and Hogan & Hartson also participated in the meeting. At the outset of the meeting, the independent members of the company's board of trustees discussed the matters considered by the Executive Compensation Committee without Mr. Sellers present, and the company's board then approved the amendments to the change in control agreements and the company's severance plan. During the meeting, Mr. Schweitzer and representatives of Morgan Stanley and Hogan & Hartson updated the board on the negotiations with Tishman Speyer/Lehman Brothers that had taken place since the last meeting of the board. Representatives of Hogan & Hartson then reviewed the board's duties in considering the proposed transaction and summarized in detail the principal terms of the merger agreement and ancillary documents, including the terms of the preferred units to be offered to operating trust common unitholders.

        Representatives of Morgan Stanley then reviewed, among other things, the history of the negotiations with Tishman Speyer/Lehman Brothers and Company A and the financial terms of the proposed transaction and presented certain financial analyses regarding the proposed transaction, including the dividend rate and other terms of the preferred units. Mr. Sellers and representatives of Hogan & Hartson then reviewed with the board the primary terms of the employment term sheet that Mr. Sellers had agreed to with Tishman Speyer/Lehman Brothers. The company's board members then engaged in substantial discussion concerning the transaction. Following that discussion, Morgan Stanley rendered its oral opinion, which was subsequently confirmed in writing, to the company's board of trustees that, as of May 28, 2007 and based upon and subject to the factors and assumptions set forth therein, the $60.75 per common share, in cash, to be received by the company's common shareholders pursuant to the merger agreement was fair from a financial point of view to such shareholders. Morgan Stanley's fairness opinion did not, however, address the fairness or value of either the cash consideration or the Series O preferred units that the holders of Class A-1 common units may receive, and was not directed to the company, in its capacity as our sole trustee, or any party other than the company's board of trustees. Further discussion of the proposed transaction followed, including discussion during which Mr. Sellers recused himself and left the meeting. After its deliberations, the company's board of trustees, among other things, unanimously approved the merger agreement, the mergers and the other transactions contemplated by the merger agreement and resolved to recommend that the company's common shareholders vote for approval of the company merger and the other transactions contemplated by the merger agreement. Certain of the factors considered by the company's board of trustees are described in greater detail under the heading "Reasons for the Mergers."

        On the morning of May 29, the company and Tishman Speyer/Lehman Brothers executed the merger agreement and issued a joint press release announcing the execution of the merger agreement.


Reasons for the Mergers

        In reaching its decision to approve the mergers, the merger agreement and the other transactions contemplated by the merger agreement, the company's board of trustees consulted with the company's senior management team, as well as the company's outside legal and financial advisors, and considered a number of factors, including the following material factors which it viewed as supporting its decision to approve the mergers, the merger agreement and the other transactions contemplated by the merger agreement and to recommend approval of the company merger, the merger agreement and the other transactions contemplated by the merger agreement to the company's common shareholders:

62


63


64



Reasons Against the Mergers

        The company's board of trustees also considered the following potentially negative factors in its deliberations concerning the mergers, the merger agreement and the other transactions contemplated by the merger agreement:

65



Conclusion of Archstone-Smith Trust's Board of Trustees Concerning the Mergers

        The company's board of trustees, after careful consideration, unanimously approved the mergers, the merger agreement and the other transactions contemplated by the merger agreement, and has declared the merger agreement, the mergers and the other transactions contemplated by the merger agreement advisable, fair to and in the company's best interests and the best interests of our Class A-1 common unitholders and the company's shareholders.


No Fairness Opinion for the Operating Trust Merger

        No fairness opinion, appraisal or other determination of a financial advisor or any other third party was requested or obtained by us, the company, as our sole trustee, or the company's board of trustees with respect to the fairness or value of either the cash consideration or the Series O preferred units that the holders of Class A-1 common units may receive in connection with the election and the operating trust merger. The fairness opinion rendered by Morgan Stanley dated May 28, 2007 did not address any consideration to be received by the holders of Class A-1 common units (whether in the form of cash or securities) and was not directed to the company, in its capacity as our sole trustee, or any party other than the company's board of trustees. Morgan Stanley's opinion does not constitute a recommendation to our unitholders with regard to the election in connection with the operating trust merger and should not be relied upon by you.


No Recommendation Regarding the Election

        None of the operating trust, the company, in its capacity as our sole trustee, or the board of trustees of the company has made, or is making, any recommendation to our unitholders with regard to the election in connection with the operating trust merger, and none of them has authorized any other person to make such a recommendation. You must make your own investment decision whether to elect to receive the cash consideration or the Series O preferred units in connection with the operating trust merger.

66




Financing

        In connection with the mergers, Parent will cause approximately $15.4 billion in the aggregate to be paid to the company's shareholders (assuming that Parent elects to cause the company to redeem all outstanding Series I preferred shares for cash consideration in accordance with the terms of the company's Series I preferred shares), our unitholders (assuming that all of the Class A-1 common unitholders elect to receive the cash consideration in full for all of their Class A-1 common units) and the holders of the company's outstanding share options, restricted share units, dividend equivalent units, phantom common shares, performance units, and share appreciation rights.

        In connection with the execution and delivery of the merger agreement, Parent has obtained an equity commitment letter from TS Fund VII to provide Parent with equity financing in an aggregate amount of up to $250.0 million and from Lehman Brothers, Real Estate Private Equity Inc. and Banc of America Strategic Ventures, Inc. to provide Parent with equity financing in an aggregate amount of up to $4.85 billion.

        Each of the equity commitments is generally subject to the satisfaction or waiver of all conditions to Parent's obligation to effect the closing of the mergers under the merger agreement in accordance with its terms. Each of the equity commitment letters will terminate on the earliest of (i) the termination of the merger agreement, (ii) the assertion by the company or any of the company's affiliates of any claim under the guarantee described below or otherwise against the buyer parties or (iii) December 31, 2007.

        Parent also obtained a debt commitment letter, dated May 28, 2007, from the lenders and certain of their affiliates, pursuant to which the lenders have committed to provide, subject to the conditions set forth therein, debt financing in an aggregate amount of up to $17.1 billion for the purpose of financing the mergers, funding reserves, refinancing a portion of the company's existing debt, and for other costs and expenses related to the mergers. The debt commitment letter terminates on December 31, 2007, unless extended in accordance with its terms and is conditioned on the completion of the mergers and other customary conditions. The lenders have the right to terminate the debt commitment letter under certain circumstances, including if the buyer parties are entitled to terminate the merger agreement due to a breach of certain representations and warranties by the company or a material adverse effect with respect to the company.

        Lehman Brothers Inc. and Banc of America Securities LLC have been appointed to act as co-lead arrangers and joint bookrunners for the debt financing.

        The availability of the debt financing is subject to customary closing conditions, including:

67


        The merger agreement does not contain a financing condition. Parent has obtained the equity and debt financing commitments described above and is obligated to use its reasonable best efforts to negotiate definitive agreements with respect to the debt financing commitment and to satisfy all conditions of the buyer parties in such definitive agreements. In the event that any portion of Parent's debt financing becomes unavailable on the terms and conditions contemplated in the debt commitment letter, Parent is obligated to use its reasonable best efforts to obtain such portion from alternative sources. Parent is also obligated to keep the company informed of the status of its efforts to arrange debt financing and to give the company prompt notice of any material breach by any party of the debt commitment letter or of any termination of the debt commitment letter. Before Parent permits any material amendment or modification to be made to, or any waiver of any material provision or remedy under, the debt commitment letter which would or would be reasonably expected to materially and adversely affect or delay in any material respect Parent's ability to consummate the mergers, Parent must first obtain the company's written consent. With certain exceptions, the company has agreed to provide, and to cause the company's subsidiaries (including us) and the company's and the company's subsidiaries' representatives to provide, all reasonable cooperation in connection with the arrangement of the debt financing as may be reasonably requested by Parent.

        If all other closing conditions have been satisfied or waived but Parent fails to obtain adequate financing to complete the mergers, such failure will constitute a breach of its covenants under the merger agreement. In that event, so long as the company, we and the company's and our subsidiaries are not in material breach of each of our respective obligations under the merger agreement, the company would be entitled to terminate the merger agreement and receive from Parent an amount equal to all reasonable expenses incurred by the company in connection with the proposed transactions, up to $10.0 million. In addition, the company may seek to recover damages to the extent the company has incurred losses or damages in connection with the merger agreement from the buyer parties up to an aggregate amount of $1.5 billion.


Guarantee and Remedies

        In connection with the merger agreement, Lehman Brothers and TS Fund VII have agreed to unconditionally and irrevocably guarantee the payment obligations of the buyer parties and any obligations to pay losses or damages under the merger agreement in an amount up to an aggregate of $1.5 billion, consisting of a $1.25 billion guarantee from Lehman Brothers and a $250.0 million guarantee from TS Fund VII. Each of the guarantees will terminate on the earliest of (a) the closing of the mergers and payment of all obligations due by the buyer parties under the merger agreement at such time, (b) termination of the merger agreement by mutual written consent or under circumstances in which the buyer parties would not be obligated to make any payments or (c) one year following a termination under circumstances in which the buyer parties are obligated to make payments (except as to payments for which a claim has been made under the applicable guarantee).

        The company cannot seek specific performance to require the buyer parties to complete the mergers, and the company's exclusive remedy for the failure of the buyer parties to complete the

68



mergers is to seek to recover damages or losses incurred by the company up to an aggregate amount of $1.5 billion, as supported by the guarantees of TS Fund VII and Lehman Brothers described above.


Interests of Our Trustees and Executive Officers in the Mergers

        Our executive officers and the company and its board of trustees may be deemed to have interests in the mergers that are in addition to or different from the interests of our unitholders generally, which interests are described more fully below. the company and the company's board of trustees were aware of these interests and considered them among other matters in approving the merger agreement.

        As of July 10, 2007, our executive officers and the company's trustees held an aggregate of 536,493 options to purchase 536,493 common shares of the company (all of which were vested with the exception of 217,166 share options held by Mr. Smith), 595,197 restricted share units and deferred restricted share units, 55,183 dividend equivalent units and deferred dividend equivalent units, 276,419 performance units, and 2,194 phantom shares.

        Under the terms of the merger agreement:

        The following table sets forth, for each of our executive officers and members of our board of trustees, as of July 10, 2007 and based on the common share merger consideration of $60.75 per share, (a) the number and value of vested and unvested share options with exercise prices less than the common share merger consideration, (b) the value of unvested restricted share units held, (c) the value of unvested and vested dividend equivalent units held that have not been deferred, (d) the value of performance units held and (e) the aggregate resulting consideration received as a result of the company merger. The following table does not include, however, the value of any deferred compensation, including deferred restricted share units and dividend equivalent units held by our

executive officers and trustees. Such information is included in a separate table below under the caption "—Deferred Compensation Plan."

        Pursuant to the merger agreement, all of the company's restricted share units, dividend equivalent units and phantom shares deferred under the Archstone Deferred Compensation Plan automatically will become fully vested and free of any forfeiture restrictions immediately prior to the company merger effective time, and each such restricted share unit, dividend equivalent unit and phantom share will be considered an outstanding common share for purposes of the merger agreement, including the right to receive the $60.75 common share merger consideration.

        Pursuant to the merger agreement, the company will take such actions as are necessary to terminate the Archstone Deferred Compensation Plan in a manner that is compliant with Section 409A of the Code. Payment of amounts deferred under the Deferred Compensation Plan will be made in cash to the participants in the plan in a single lump-sum payment on the first business day following January 1, 2008; provided, however, that payments under the plan will be made immediately following the company merger effective time if the parties mutually agree that the making of such payments will not cause participants in the Deferred Compensation Plan to incur any adverse tax consequences under Section 409A of the Code.

        The following table sets forth the amounts of deferred cash and equity compensation held by our executive officers and trustees as of July 10, 2007 to which they would be entitled in connection with the mergers under the Deferred Compensation Plan.

        Under the change in control agreements that the company has entered into with each of R. Scot Sellers, Charles E. Mueller, Caroline Brower, Alfred G. Neely and Mark A. Schumacher, the amended terms of which the company's board of trustees approved on May 28, 2007, if a change in control (which would include the company merger) occurs and during the applicable protection period (three years from the date of the change in control in the case of Mr. Sellers, two years in the case of Mr. Mueller and Ms. Brower, and one year in the case of Messrs. Neely and Schumacher), the

71


executive officer experiences a constructive termination (as described below), the executive officer will receive the following severance payments and benefits:

        The change-in-control employment agreements also require the company to make the executive officers whole for any "excess parachute payment" excise taxes that they might incur as a result of the receipt of certain payments and benefits (including the severance payments and benefits described above) in connection with the closing of the mergers.

        A constructive termination includes (i) a termination by the company for any reason other than death, disability or cause, and (ii) a resignation of the executive upon the occurrence of (a) a material adverse change in his title, position, authorities or duties (including, in the case of Ms. Brower and Messrs. Sellers, Mueller and Schumacher, the executive no longer having responsibilities related to the company being publicly traded), (b) a breach of the company's obligations under the agreement, (c) the relocation of the executive's office to a location more than 30 miles from the location of the executive's office immediately prior to the change in control, and (d) the company's failure to obtain a satisfactory agreement from any successor to assume and agree to the performance of the agreement.

        As discussed more fully under the section entitled "—Arrangement with R. Scot Sellers" below, Mr. Sellers has entered into a term sheet with Parent regarding his future employment and compensation which will supersede his change in control agreement with the company following the closing of the mergers.

        The following table sets forth an estimate of the potential cash severance payments that could be payable as described above in the event the executive officer becomes entitled to such severance amount pursuant to their change in control agreements following the company merger (assuming for illustrative purposes that the executive officer's employment is terminated on September 30, 2007 and utilizing current base salaries and the bonus compensation amounts provided for in the agreements). The table does not include an amount for the value of the accelerated vesting and cash out of equity-based awards, which is described above. The table also does not include the amounts payable to Mr. Freeman under his change in control agreement. Instead, in connection with his previously announced retirement, he will receive payments and benefits pursuant to the terms of a separation and

72



release agreement that the company and Mr. Freeman have agreed in principle, as more fully described below under "—Agreement with J. Lindsay Freeman."

As discussed more fully under the section entitled "—Arrangement with R. Scot Sellers" below, Mr. Sellers has entered into a term sheet with Parent regarding his future employment and compensation whereby he will forgo payments to which he may be entitled under his current change in control agreement with the company in connection with the mergers.

        On May 28, 2007, Mr. Sellers entered into a term sheet with Parent regarding Mr. Sellers' employment with MergerCo following the closing of the mergers. The term sheet (or the definitive documents executed to reflect the agreement set forth in the term sheet) will become effective at the closing and will supersede most provisions of the change in control agreement that the company previously entered into with Mr. Sellers (which is described above). Among other things Mr. Sellers has agreed to waive, upon and subject to consummation of and only in connection with the mergers, his right to receive severance payments under the change in control agreement in connection with the mergers. The term sheet sets forth the material terms of Mr. Sellers' employment with MergerCo and the parties have agreed to negotiate definitive agreements with MergerCo (including, but not limited to, an employment agreement, and equity compensation agreements) that are consistent with the applicable provisions of the term sheet. The term sheet will be void if the merger agreement is terminated in accordance with its terms, but will otherwise generally be binding except in certain limited circumstances.

        Following the closing, Mr. Sellers will serve as the Chief Executive Officer of MergerCo. The initial term of Mr. Sellers' employment with MergerCo will end on December 31, 2010, but will automatically be extended for consecutive one year periods upon the expiration of the initial term (or any extension thereof) unless either party provides no less than 90 days notice of its intention not to renew. Mr. Sellers will be entitled to an annual base salary of $750,000. Mr. Sellers is guaranteed a bonus of $4.0 million for the fiscal year ending December 31, 2008 and $2.0 million for each subsequent fiscal year, and will be entitled to an additional incremental bonus of up to $3.125 million per year based on achieving certain equity raising milestones. Mr. Sellers will have the right to reinvest up to 50% of his annual bonus into equivalent phantom interests in MergerCo.

        As of July 10, 2007, Mr. Sellers owned 93,796 of the company's common shares for which he will receive the common share merger consideration in the company merger on the same basis as the company's other common shareholders. Additionally, in lieu of receiving cash for his share options, Mr. Sellers has agreed to roll over his options to purchase 218,354 of the company's common shares into fully vested options to purchase units in MergerCo and GP interests. If Mr. Sellers cannot roll over the company's share options into options to purchase interests in GP on a tax efficient basis, 50% of his share options will be cashed out at the closing on the same terms as all other employee share options in the company merger and Mr. Sellers will purchase $4.1 million of GP interests. At the closing, Mr. Sellers will also receive new units in MergerCo or phantom equity grants with a value of

73



$11.25 million. Generally, these grants will vest on the third anniversary of the closing date of the company merger.

        At the closing, Mr. Sellers will be granted 600 performance units that will have a performance based value and which will generally vest ratably on each of the first seven anniversaries of the closing, provided, that vesting will accelerate upon a future change in control. All performance units that are not vested upon termination of employment will be forfeited, subject to any prior vesting or acceleration.

        Termination payments to Mr. Sellers depend upon the timing and circumstances of termination of Mr. Sellers' employment, and will generally include the payment of (i) certain "accrued obligations," (ii) any vested grants, and (iii) amounts based upon Mr. Sellers' base salary and bonuses he earned, or otherwise would in the future be entitled to receive, depending on the timing of such termination.

        In the event that any payments made in connection with the mergers subject Mr. Sellers to a "golden parachute" excise tax, Mr. Sellers will be made whole for such excise tax. Additionally, in the event that MergerCo has any stock which is traded on an established securities market on the date of any subsequent transaction, Mr. Sellers will be entitled to the same make whole protection for any payment made to Mr. Sellers in connection with such subsequent transaction.

        Following the company merger, Mr. Sellers will be subject to substantially identical restrictive covenants that are currently provided in his employment arrangement, except that (i) his non-solicit and non-hire restriction will be extended from one to two years in the event his employment is terminated on or after December 31, 2010, (ii) the restrictive covenants will prohibit solicitation of investors and will apply to Tishman Speyer, Lehman Brothers and their respective affiliates, and (iii) Mr. Sellers will be subject to a one-year post-termination non-competition covenant.

        The term sheet permits Mr. Sellers to negotiate the terms of his continued employment with any third party that submits a competing acquisition proposal that the company's board of trustees has determined is a superior proposal (as defined by the merger agreement), subject to the condition that, subsequent to such determination of superiority, we are prepared and entitled to deliver a superior proposal notice to the buyer parties, and certain other conditions. The arrangement terminates upon the termination of the merger agreement in accordance with its term.

        We have agreed in principle to the terms of a separation and general release agreement with J. Lindsay Freeman, effective as of December 31, 2007 pursuant to which Mr. Freeman agrees to resign as the company's and our Chief Operating Officer effective December 31, 2007 but will continue to be employed through December 31, 2008. During the term of Mr. Freeman's continued employment, he will continue to be paid an annual base salary of $450,000 and will continue to be eligible for all benefits generally available to employees of the company provided that he is not eligible for any bonus or stock-based award for services performed after 2007.

        On May 28, 2007, the company's board of trustees approved an adjustment to Mr. Freeman's separation arrangement pursuant to which Mr. Freeman will be paid $1.0 million if he remains an employee of the company following the mergers and through December 31, 2007 (or if he is terminated without cause following the consummation of the mergers and before December 31, 2007). Such payment is contingent upon Mr. Freeman agreeing to waive any payments he may have otherwise become entitled to receive under his change in control agreement, if any, other than the requirement that the company make him whole for any "excess parachute payment" excise taxes that he might incur.

74



        We currently anticipate that our existing executive officers will remain executive officers following the completion of the mergers. Parent has finalized Mr. Sellers' employment term sheet and is working with Mr. Sellers to put in place a new incentive plan with the focus of retaining our current executive officers. No terms of any such plan have yet been determined. We have agreed in principle to the terms of a separation and general release agreement with Mr. Freeman pursuant to which Mr. Freeman has agreed to resign as our Chief Operating Officer effective December 31, 2007, but will continue to be employed through December 31, 2008. During the term of Mr. Freeman's continued employment, he will continue to be paid an annual base salary of $450,000.

        The company typically has made annual awards of restricted share units to certain officers, including the executive officers. These awards have been granted at the beginning of each fiscal year in consideration of an employee's performance for the prior fiscal year. As the company merger is anticipated to be consummated during the third quarter of 2007, the board of trustees determined to grant to certain officers a cash award generally equal to the value of 75% of such officers' award of restricted share units for the 2006 fiscal year. The cash awards the company's executive officers will receive, contingent upon and paid upon the consummation of the company merger, are as follows:

Executive Officers

  Amount of
Cash Award(1)

R. Scot Sellers   $ 2,454,962
Charles E. Mueller     637,273
Caroline Brower     256,931
Alfred G. Neely     487,484
Mark A. Schumacher     131,236

(1)
Mr. Freeman is already entitled to receive a restricted share unit grant pursuant to the agreed-upon terms of his separation and release agreement.

        The company's employees who were granted restricted share units, share options and dividend equivalent units prior to 2006 earn and are entitled to receive dividend equivalent units on such awards based on amounts equal to, and to correspond with, the dividends that the company pays to the company's common shareholders. The dividend equivalent units earned for each year have typically been credited in January of the year following the year in which dividends have been paid. As the company merger is anticipated to be consummated during the third quarter of 2007, the executive compensation committee of the company's board of trustees determined to pay to each of the company's employees holding restricted share units, share options and dividend equivalent units that were granted prior to 2006 a cash payment equal to the value of the dividend equivalent units that such individual already earned based on dividends that the company paid in the first and second quarters of 2007. However, because the company is not permitted to declare or pay any regular dividends on the company's common shares under the merger agreement, our executive officers generally will not earn any additional dividend equivalent units or cash value thereof prior to the completion of the mergers.

75


Such cash payments that our executive officers have earned and will receive in connection with such grant are as follows:

Trustee and Executive Officer Indemnification Insurance

        The merger agreement provides that for a period of at least six years after the company merger effective time, the organizational documents of the surviving entity will contain indemnification provisions that are no less favorable than the indemnification provisions in the company's existing declaration of trust and bylaws, and that those provisions will not be modified during that period in any manner that would affect adversely the rights of any person who at or prior to the company merger effective time were the company's or the company's subsidiaries' directors, officers, trustees, employees, agents, or fiduciaries or fiduciaries with respect to any of the company's or the company's subsidiaries' employee benefit plans, except as required by law and then only to the minimum extent required by law.

        The surviving entity has agreed to indemnify, to the fullest extent permitted by applicable law, persons who were at the date of the merger agreement or during the period between the signing of the merger agreement and the closing date serving as a director, officer or trustee, or as a fiduciary under or with respect to any of the company's or the company's subsidiaries' employee benefit plans, with respect to any legal action, suit or proceeding, or any inquiry or investigation arising out of or relating to such service occurring at or prior to the company merger effective time and, subject to certain conditions, will pay or advance related reasonable legal fees, costs, obligations and expenses incurred by them.

        The merger agreement requires that, with respect to claims arising from facts or events that occurred on or prior to the company merger effective time, the surviving entity maintain in effect, for a period of at least six years after the company merger effective time, directors' and officers' liability insurance coverage that provide for at least $50.0 million of coverage for directors' and officers' liability and $5.0 million for employed lawyer liability and that contain other terms and conditions that are, in the aggregate, not less advantageous to the insured person than the policies maintained by the company and the company's subsidiaries as of the date of the merger agreement. This requirement is subject to a specified maximum cost of coverage of $3.0 million in the aggregate. If the cost per year of insurance coverage exceeds such maximum amount, the surviving entity must obtain as much comparable insurance as possible for such amount. Parent and the surviving entity may meet these obligations by purchasing a "tail policy" providing coverage in the required amounts and on other terms and conditions which are, in the aggregate, not less advantageous to the insured persons than the policies maintained by the company, the operating trust, and our respective subsidiaries.

        Parent and the surviving entity have agreed that all rights to indemnification and exculpation from liabilities for acts or omissions occurring at or prior to the company merger effective time now existing in favor of the current or former directors, officers, trustees, employees, agents or fiduciaries of the company or the company's subsidiaries as provided in the company's existing declaration of trust and bylaws (or, as applicable, the charter, bylaws, partnership agreement, limited liability company agreement or other organizational documents of any of our subsidiaries) and certain indemnification

76



agreements of the company or the company's subsidiaries will be assumed by the surviving entity and will continue in full force and effect.

        The merger agreement provides that Parent will have the right to participate in the defense or settlement of any shareholder or member litigation against the company, the company's trustees or officers, or the operating trust relating to the mergers or the other transactions contemplated by the merger agreement; provided, however, that no such settlement will be agreed to without Parent's consent, which consent will not be unreasonably withheld.

        The obligations described above regarding trustees' and officers' indemnification, and directors' and officers' liability insurance must be assumed by any successor entity to the surviving entity as a result of any consolidation, merger or transfer of all or substantially all of its properties and assets.


Regulatory Approvals

        EC No. 139/2004 requires notification to and prior approval by the European Commission of mergers or acquisitions involving parties with aggregate worldwide sales and individual European Union sales exceeding specified thresholds. We and the buyer parties have determined that the mergers are subject to filing requirements under EC No. 139/2004. Once a complete notification is filed, the European Commission has an initial (Phase I) period of 25 working days from the day following the date of notification, which period may be extended under certain circumstances, in which to consider whether the mergers would significantly impede effective competition in the common market or a substantial part of it, in particular as a result of the creating or strengthening of a dominant position. By the end of this Phase I period, the European Commission must issue a decision either clearing the mergers or opening an in-depth Phase II investigation. A Phase II investigation can extend the investigation period up to an additional 125 working days.

        In addition, we are required to make filings under the securities, or "blue sky," laws of certain states with regard to the election being afforded to holders of Class A-1 common units to receive cash consideration or Series O preferred units, or a combination thereof, in exchange for their Class A-1 common units. In certain states we will not be able to proceed with the mergers unless the operating trust has obtained the confirmation of the availability of an applicable exemption and/or qualification of the issuance of the Series O preferred units. In other states, approval of the filing and the contents of this prospectus/information statement, pursuant to which the Series O preferred units would be offered, may be required before the operating trust can offer the election or issue Series O preferred units to holders of Class A-1 common units who are residents of those states. Accordingly, we will not be able to consummate the mergers until any necessary approvals under applicable state securities laws are obtained.

        Other than EC No. 139/2004, the Form S-4 of which this prospectus/information statement forms a part becoming effective, our obtaining any necessary approvals under state securities or "blue sky" laws and the filing of articles of merger by each of the company and the operating trust with the SDAT, we are unaware of any other material federal, state or foreign regulatory requirements or approvals that may be required to consummate the mergers.

        Under the terms of the merger agreement, the company, the operating trust, and the buyer parties have agreed to make promptly their respective filings and any other required submissions under any applicable antitrust or competition laws and any other laws with respect to the mergers. In addition, the company, the operating trust and the buyer parties have agreed to use commercially reasonable efforts to take all appropriate actions and do all things necessary, proper or advisable under applicable laws to consummate and make effective the mergers and the other transactions contemplated by the merger agreement, including using commercially reasonable efforts to obtain all permits, consents, approvals, authorizations, qualifications and orders of governmental authorities as are necessary for the

77



consummation of the transactions contemplated by the merger agreement and to fulfill conditions to the company merger and the transactions contemplated by the merger agreement.


Litigation Relating to the Mergers

        On May 30, 2007, two separate purported shareholder class action lawsuits related to the merger agreement and the transactions contemplated thereby were filed naming the company and each of the company's trustees as defendants. One of these lawsuits, Seymour Schiff v. James A. Cardwell, et al. (Case No. 2007cv1135), was filed in the United States District Court for the District of Colorado. The other, Mortimer J. Cohen v. Archstone-Smith Trust, et al. (Case No. 2007cv1060), was filed in the District Court, County of Arapahoe, Colorado. On May 31, 2007, two additional purported shareholder class action lawsuits related to the merger agreement and the transactions contemplated thereby were filed in the District Court, County of Arapahoe Colorado. The first, Howard Lasker v. R. Scot Sellers, et al. (Case No. 2007cv1073), names the company, each of the company's trustees and one of the company's senior officers as defendants. The second, Steamship Trade Association/International Longshoremen's Association Pension Fund v. Archstone-Smith Trust, et al. (Case No. 2007cv1070) names the company, each of the company's trustees, Tishman Speyer and Lehman Brothers as defendants. On June 11, 2007, an additional purported shareholder class action lawsuit related to the merger agreement, Doris Staehr v. Archstone-Smith Trust, et al (Case No. 2007cv1081), was filed in the District Court, County of Arapahoe Colorado, naming the company and each of the company's trustees as defendants. All five lawsuits allege, among other things, that the company's trustees violated their fiduciary duties to the company's shareholders in approving the mergers.

        All five lawsuits purport to be brought as class actions and seek to enjoin the completion of the mergers and the related transactions. In addition, among other things, the complaints in each of Seymour Schiff v. James A. Cardwell, et al. and Howard Lasker v. R. Scot Sellers, et al. seek compensation for all losses and damages allegedly suffered by class members as a result of the transactions (the Lasker complaint requests compensatory damages and/or rescission of the company merger) and the complaints in Mortimer J. Cohen v. Archstone-Smith Trust, et al. and Doris Staehr v. Archstone-Smith Trust seek an order directing the company to obtain a transaction which is in the best interests of the company's shareholders.

        On June 21, 2007, the District Court, County of Arapahoe Colorado entered an order consolidating the Lasker, Steamship Trade Association/International Longshoremen's Association Pension Fund and Staehr actions into the Cohen action, under the caption In re Archstone-Smith Trust Shareholder Litigation. We intend to vigorously defend these actions.

THE ELECTION

General

        Pursuant to the merger agreement, at the operating trust merger effective time, each Class A-1 common unit of the operating trust issued and outstanding immediately prior to the operating trust merger effective time (other than units held by unitholders who have properly exercised and perfected their appraisal rights, if any, under Maryland law) will automatically be converted into one Series O preferred unit. Alternatively, as a Class A-1 common unitholder, you have the right to elect to receive for your Class A-1 common units:

        Enclosed with this prospectus/information statement as Attachment A is an election form package that contains the form, transmittal materials and other documents necessary in connection with making the election.


Receipt of Series O Preferred Units

        If you wish to receive only Series O preferred units for your Class A-1 common units, you may, but are not required to, complete, execute and return the documents included in the election form package (as described above) by the election deadline or, if you do not submit an election form prior to the election deadline, you will automatically receive Series O preferred units in the operating trust merger in exchange for your Class A-1 common units. However, if you received a certificate representing your Class A-1 common units, you must deliver such certificate and complete, execute and return the elction form. If you received a certificate representing your Class A-1 common units and such certificate has been lost, stolen or destroyed, you are required to make an affidavit that such certificate has been lost, stolen or destroyed, a form of which is attached to the election form as Attachment 3.


Election to Receive Cash Consideration

        In order to elect to receive cash consideration for your Class A-1 common units, you must properly complete, execute and return the documents described below, in accordance with the instructions in the election form package by the election deadline of 5:00 P.M. New York City Time on     •    ,    •    , 2007:


        The buyer parties have informed us that they believe that any tax protection agreement with respect to which you, as a Class A-1 common unitholder, may be a beneficiary or a party (including, in the case of applicable Class A-1 common unitholders, tax protection provisions set forth in an annex to our existing declaration of trust) shall not apply to any gain that is recognized with respect to your Class A-1 common units for which you are electing to receive the cash consideration as a result of your receipt of the cash consideration. Accordingly, if you elect to receive cash consideration, in whole or in part, the buyer parties intend to take the position that you are not entitled, and the buyer parties and

79


we do not intend to pay you, any additional consideration with respect to any federal, state, local or other taxes payable by you in connection with your election to receive cash.

        In addition to the documents described above, if you received a certificate representing your Class A-1 common units, you must deliver such certificate, regardless of whether you elect to receive the cash consideration or the Series O preferred units for your Class A-1 common units. If you received a certificate representing your Class A-1 common units and such certificate has been lost, stolen or destroyed, you are required to make an affidavit of the fact that such certificate has been lost, stolen or destroyed, a form of which is attached as Attachment 3 to the election form. If you did not receive a certificate for your Class A-1 common units, you are not required to deliver any certificates.

        Further, to avoid possible FIRPTA withholding tax and to ensure proper back-up withholding, if applicable, from the payment of the cash consideration, you will need to complete, sign and return to MergerCo, as our sole trustee after the mergers, the Substitute Form W-9 (located in Box 2 on the front of the election form) and FIRPTA certificate, which is attached to the election form included in the election form package as Attachments 1A or 1B. Otherwise, the cash consideration minus any required tax withholding will be paid to you by the paying agent as soon as practicable after the completion of the operating trust merger. Registered mail with return receipt requested or overnight delivery by a nationally recognized overnight courier service is recommended. In all cases, sufficient time should be allowed to ensure delivery.

        Instructions for returning the election form and any necessary attachments are in the section entitled "Instructions for Return of Completed Election Forms and Necessary Attachments" in the election form package.

        Each of the forms described above must actually be received by MergerCo, as our sole trustee after the mergers, on or before the election deadline, as more fully described in the election form package, in order for you to receive any cash consideration. If you do not make a timely, valid election as provided in the election form package by the election deadline, you will only be entitled to receive, for each Class A-1 common unit, one Series O preferred unit and you will not be entitled to receive any cash consideration.


Partial Elections

        If you wish to receive cash consideration with respect to some but not all of your Class A-1 common units, you must specify the number of whole Class A-1 common units for which you are electing to receive the cash consideration. You cannot elect to receive fractional Series O preferred units or cash consideration for less than a whole number of Class A-1 common units. If you do not clearly specify the allocation, even if you otherwise properly complete, execute and return the election form and all necessary attachments by the election deadline, you will only be entitled to receive the Series O preferred units for all your Class A-1 common units. As a result, if you wish to receive any cash consideration, it is very important that you specify your allocation when you timely return a properly completed and executed election form and all necessary attachments by the election deadline.


Revocation or Failure to Make Election

        You may revoke any properly completed and timely delivered election form at any time prior to the election deadline by submitting to MergerCo, as our sole trustee after the mergers, a completed and executed revocation of election form, which is included in the election form package. Any effective election properly revoked will be deemed not to have been validly made, and you must properly complete and execute a new election form and all necessary attachments and return it prior to the election deadline in order to make a new valid election.

        If you make no election or fail to properly make the election pursuant to the procedures set forth in this prospectus/information statement and the election form package, or if you revoke your election and do not return a properly completed new election form and all necessary attachments prior to the election deadline, you will automatically be entitled to receive one Series O preferred unit for each

80



Class A-1 common unit that you own immediately prior to the operating trust merger effective time and you will not receive any cash consideration for your Class A-1 common units.

        As a holder of approximately 89.3% of all of our outstanding common units, the company's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement. This approval is expected to be effective 20 days after the date of this prospectus/information statement. You are being sent this prospectus/information statement solely in connection with your right to elect, for each Class A-1 common unit you hold, either the operating trust cash consideration or one Series O preferred unit.

        If you wish to receive the cash consideration for some or all of your Class A-1 common units, Mellon Investor Services, LLC must receive a properly completed election form that has not been revoked by no later than 5:00 p.m., New York City time, on    •     , 2007, the election deadline. If you make no election pursuant to the procedures set forth in this prospectus/information statement and the election form package, or if you revoke your election and do not return a properly completed new election form prior to the election deadline, you will automatically receive one Series O preferred unit for each Class A-1 common unit you currently hold and you will not be entitled to receive any cash consideration.

        The reasonable determination of the company, after consultation with the buyer parties, shall be binding as to questions of validity, form, eligibility, time of receipt and whether elections to receive the operating trust cash consideration have been properly made or revoked.

81



THE MERGER AGREEMENT

        The following summarizes material provisions of the merger agreement, as amended by Amendment No. 1 thereto, copies of which are attached to this prospectus/information statement as Annex A and which we incorporate by reference. This summary may not contain all of the information about the merger agreement that is important to you. Therefore, we recommend that you read carefully the merger agreement attached to this prospectus/information statement as Annex A in its entirety, as the rights and obligations of the parties are governed by the express terms of the merger agreement and not by this summary or any other information contained in this prospectus/information statement.

        The merger agreement contains representations and warranties made by, and to, us, the Company, Parent, MergerCo and Operating Trust MergerSub. These representations and warranties, which are set forth in the merger agreement attached as Annex A, were made for the purposes of negotiating and entering into the merger agreement between the parties. In addition, these representations and warranties were made as of specified dates, may be subject to standards of materiality different from what may be viewed as material to unitholders, or may have been used for the purpose of allocating risk between the parties instead of establishing such matters as facts. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this prospectus/information statement, may have changed since the date of the merger agreement and subsequent developments or new information qualifying a representation or warranty may have been included in this prospectus/information statement.


Structure

        On the closing date of the mergers, Operating Trust MergerSub will merge with and into the operating trust, Operating Trust MergerSub's separate existence will cease and the operating trust will survive the operating trust merger and continue to exist as the surviving operating trust.

        Immediately after the effective time of the operating trust merger, the company will merge with and into MergerCo, the company's separate existence will cease and MergerCo will survive the company merger and continue to exist as the surviving entity. MergerCo will become the sole trustee of the operating trust following the mergers.


Effective Times and Closing

        The operating trust merger effective time will occur under all applicable laws upon (a) the time the operating trust articles of merger are accepted for record by the SDAT or (b) such later time agreed to by the parties to the merger agreement and designated in such filing in accordance with the Maryland REIT Law and the Maryland Limited Liability Company Act, which we refer to as the "LLC Act," but not to exceed 30 days after the operating trust articles of merger are accepted for record by the SDAT and the LLC Act, which we refer to as the "operating trust merger effective time."

        The company merger effective time will occur under applicable law at (a) the time the articles of merger (relating to the company merger) are accepted for record by the SDAT or (b) such later time agreed to by the parties to the merger agreement and designated in such filing in accordance with the Maryland REIT Law and the Maryland Revised Uniform Partnership Act but not to exceed 30 days after the articles of merger are accepted for record by the SDAT or prior to the operating trust effective time. It is the intention of the parties that the company merger effective time will occur immediately after the operating trust merger effective time.

        Unless the merger agreement is terminated in accordance with its terms, the closing of the mergers must occur as promptly as practicable (but in no event later than the third business day) after all of the

82



conditions to the closing of the mergers are satisfied or appropriately waived or at such other time and date mutually agreed by the parties. The buyer parties are not required to consummate the closing during the period beginning on August 15, 2007 and ending on October 4, 2007.


Organizational Documents

        The certificate of limited partnership of MergerCo, as in effect immediately prior to the company merger effective time, will be the certificate of limited partnership of the surviving entity in the company merger until amended as provided therein or with applicable law.

        The new declaration of trust, which will give effect to the provisions of the merger agreement and such other provisions which are not inconsistent with the merger agreement as determined by Parent in its sole discretion, will be the declaration of trust of the surviving operating trust after the operating trust merger until amended as provided therein or with applicable law.


Trustees and Officers

        The directors of MergerCo immediately prior to the company merger effective time will be the initial directors of the surviving entity, and the officers of MergerCo immediately prior to the company merger effective time will be the initial officers of the surviving entity, each to hold office in accordance with the surviving entity charter. The surviving entity will be the sole trustee of the surviving operating trust immediately after the company merger effective time. For disclosure on the directors and officers of the operating trust after the operating trust merger, see "Archstone-Smith Operating Trust After the Mergers—Trustees and Officers After the Mergers" on page 152.


Treatment of Common Shares and Series I Preferred Shares

        At the company merger effective time, each of the company's common shares issued and outstanding immediately prior to the company merger effective time (other than shares owned by the company, the company's subsidiaries or MergerCo) will automatically be converted into, and canceled in exchange for, the right to receive an amount in cash of $60.75 per common share, without interest and less applicable withholding taxes. The company's common shareholders who object to the company merger do not have any appraisal rights or dissenters' rights in connection with the company merger. However, the company's common shareholders can vote against the company merger and the other transactions contemplated by the merger agreement.

        At the company merger effective time, each Series I preferred share issued and outstanding immediately prior to the company merger effective time (other than Series I preferred shares held by the company or the company's subsidiaries) will, at the election of Parent, either automatically be converted into, and canceled in exchange for the right to receive, one surviving entity Series I preferred share, or be redeemed at the closing of the mergers by the company for the applicable liquidation preference of $100,000 per share, plus all dividends (whether or not earned or declared) accrued and unpaid thereon to the redemption date, without interest and less applicable withholding taxes. The terms of the surviving entity Series I preferred shares will be substantially identical to the terms of the company's Series I preferred shares. While holders of the company's Series I preferred shares are entitled to receive notice of and attend the special meeting or any adjournments or postponements of the special meeting, they are not entitled to vote upon the company merger or any of the other transactions contemplated by the merger agreement, or any adjournments or postponements of the special meeting for the purpose of soliciting additional proxies, at the special meeting. Under the Maryland REIT Law, because the holders of the company's Series I preferred shares are not entitled to

83


vote on the company merger and the other transactions contemplated by the merger agreement, they do not have any appraisal rights or dissenters' rights in connection with the company merger.


Treatment of Share Options, Restricted Share Units, Dividend Equivalent Units, Phantom Common Shares, Performance Units and Share Appreciation Rights

        Immediately prior to the company merger effective time, all of the company's outstanding share options and share appreciation rights, whether or not then vested or subject to any performance condition that has not been satisfied, will become fully vested and exercisable and all of the company's restricted share units (including any deferred restricted share units), dividend equivalent units (including any deferred dividend equivalent units), phantom common shares and performance units will become fully vested and free of forfeiture restrictions. Immediately prior to the company merger effective time, all of the company's outstanding restricted share units, dividend equivalent units, phantom common shares and performance units will be considered outstanding common shares for the purposes of the merger agreement, including the right to receive the common share merger consideration, except in each case as may otherwise be agreed to by and among the buyer parties and any individual holder of such award.

        In addition, at the company merger effective time, except in each case as may otherwise be agreed to by and among the buyer parties and any individual holder of share options or share appreciation rights, each share option and share appreciation right that remains outstanding immediately prior to the company merger effective time will be canceled in exchange for the right to receive a single lump sum cash payment equal to the product of:

        If the exercise price of any share option or share appreciation right is equal to or greater than the common share merger consideration, such option and share appreciation right will be canceled without any cash payment being made in respect of such option and share appreciation right. As of the date of this prospectus/information statement, none of the company's outstanding share options had an exercise price equal to, or greater than, the common share merger consideration.

        The amount of cash consideration payable with respect to share options, restricted share units, dividend equivalent units, phantom common shares, performance units, and share appreciation rights will be reduced by the amount of any applicable taxes required to be withheld and will be paid without any interest.


Treatment of Archstone-Smith Operating Trust Units

        In connection with the operating trust merger, at the operating trust merger effective time, Class A-1 common units issued and outstanding immediately prior to the operating trust merger effective time (other than units held by unitholders who have properly exercised and perfected their appraisal rights, if any, under Maryland law) will be automatically converted into Series O preferred units. Alternatively, the Class A-1 common unitholders may elect to receive for their Class A-1 common units, at the election of the holder, either (i) $60.75 in cash per Class A-1 common unit, without interest and less applicable withholding taxes or (ii) a combination of the cash consideration and Series O preferred units. For a discussion of the terms of the Series O preferred units, see

84


"Description of the Series O Preferred Units" on page 108 and "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders" on page 114.

        In connection with the operating trust merger, at the operating trust merger effective time and without any action on the part of the company, as the sole holder of the operating trust Class A-2 common units, each operating trust Class A-2 common unit held by the company immediately prior to the operating trust merger effective time will remain outstanding.

        In connection with the operating trust merger, at the operating trust merger effective time and without any action on the part of the company, as the sole holder of the operating trust Series I preferred units, each operating trust Series I preferred unit issued and outstanding immediately prior to the operating trust merger effective time will at the election of Parent (which election will be made no later than the date of the company shareholders' meeting) either (a) remain outstanding and unchanged as one operating trust Series I preferred unit without any material adverse change to its terms and rights or (b) be redeemed at the closing by the operating trust for the liquidation preference plus all dividends (whether or not earned or declared) accrued and unpaid thereon to the redemption date.

        In connection with the operating trust merger, at the operating trust merger effective time and without any action on the part of the holder of the operating trust Series M preferred unit, the operating trust Series M preferred unit will be converted into the right to receive one operating trust Series P preferred unit. The terms of the surviving operating trust Series P preferred unit are substantially similar to the terms of the operating trust Series M preferred unit, with certain changes to the redemption rights necessary to reflect the fact that there will no longer be Class A-1 common units outstanding. See "Comparison of Preferred Unitholders Rights—Series M Preferred Units" on page 131.

        In connection with the operating trust merger, at the operating trust merger effective time and without any action on the part of the holders of the operating trust Series N preferred units, (i) each operating trust Series N-1 preferred unit issued and outstanding immediately prior to the operating trust merger effective time will be converted into the right to receive one operating trust Series Q-1 preferred unit, and (ii) each operating trust Series N-2 preferred unit issued and outstanding immediately prior to the operating trust merger effective time will be converted into the right to receive one operating trust Series Q-2 preferred unit. The terms of the surviving operating trust Series Q preferred units are substantially similar to the terms of the operating trust Series N preferred units, with certain changes to the conversion rights necessary to reflect the fact that there will no longer be Class A-1 common units outstanding. See "Comparison of Preferred Unitholders Rights—Series N-1 and N-2 Preferred Units" beginning on page 133.


Treatment of Operating Trust MergerSub Units or Shares of Beneficial Interest

        In connection with the operating trust merger, at the operating trust merger effective time, all units or shares of beneficial interest of the Operating Trust MergerSub will automatically be converted into that number of Class A-1 common units equal to the number of Class A-1 common units electing to receive the operating trust cash consideration.

85




No Further Ownership Rights

        At the company merger effective time, holders of the company's common shares, Series I preferred shares and company equity awards will cease to be, and have no rights as, the company's shareholders or equityholders, other than the right to receive the applicable merger consideration. The applicable merger consideration will be deemed to have been paid in full satisfaction of all rights and privileges pertaining to the company's common shares, Series I preferred shares and equity awards, regardless of whether evidenced by share certificates or other similar certificates exchanged therefor.

        At and immediately following the operating trust merger effective time, each person who held, immediately prior to the operating trust merger effective time:

        The applicable merger consideration will be deemed to have been paid in full satisfaction of all rights and privileges pertaining to the operating trust common units, the operating trust Series M preferred unit and operating trust Series N preferred units, regardless of whether evidenced by unit certificates or other similar certificates exchanged therefor.


Exchange and Payment Procedures

        On or immediately after the operating trust merger effective time, Parent will deposit, or cause MergerCo or Operating Trust MergerSub to deposit, cash and securities in respect of the consideration to be paid to the holders of the company's common shares or preferred shares, or the operating trust's common units or preferred units, respectively, with a paying agent selected by Parent that is reasonably satisfactory to the company. On or immediately after the operating trust merger effective time, Parent will cause to be deposited with the operating trust the consideration for the benefit of holders of the company's options, restricted share units, dividend equivalent units, phantom shares, performance units and share appreciation rights.

86


        You will not be entitled to receive the applicable merger consideration until you surrender your certificate or certificates, if any, to the paying agent, together with a duly completed and executed letter of transmittal and any other documents as the paying agent may reasonably require. The applicable merger consideration may be paid to a person other than the person in whose name the corresponding certificate is registered if the certificate is properly endorsed or is otherwise in the proper form for transfer. In addition, the person requesting payment must either pay any applicable stock transfer taxes or establish to the satisfaction of Parent that such stock transfer taxes have been paid or are not applicable.

        No interest will be paid or will accrue on the cash payable upon surrender of the certificates. Each of the paying agent, the surviving entity, the operating trust or Parent will be entitled to deduct and withhold any applicable taxes from the merger consideration.

        At the company merger effective time, the company's share transfer books will be closed and there will be no further registration of transfers of the company's common shares or Series I preferred shares. Any share certificates presented to the paying agent, the surviving entity or the transfer agent after the closing of the share transfer books will be exchanged for the applicable merger consideration for the common shares or Series I preferred shares. The share/unit transfer books of the operating trust will continue in all respects, provided, however, that at the operating trust merger effective time there will be no further registrations or transfers of Class A-1 common units that were formerly held by the unitholders of the operating trust.

        None of the paying agent, Parent, MergerCo, Operating Trust MergerSub, the company or the operating trust or any respective employees, officers, trustees, directors, shareholders, partners, agents or affiliates will be liable to any person for any merger consideration, if the cash and securities deposited with the paying agent has been delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. Holders of the company's common or preferred shares or the operating trust's common or preferred units prior to the mergers who have not complied with the exchange and payment procedures contained in the merger agreement within 12 months after the company merger effective time may only look to the surviving entity for the payment of the merger consideration.

        If you received a certificate representing your Class A-1 common units, you must deliver such certificate regardless of whether you elect to receive the cash consideration. If you did not receive such certificate, you are not required to deliver any certificates. If you received a certificate representing your Class A-1 common units and such certificate has been lost, stolen or destroyed, you are required to make an affidavit of the fact that such certificate has been lost, stolen or destroyed in order to receive the Series O preferred units or the cash consideration for your Class A-1 common units. In order to receive the cash consideration for all or part of your Class A-1 common units, you must also timely and properly complete, execute and return the election form and all necessary attachments, including the Substitute Form W-9 (located in Box 2 on the front of the election form) or appropriate W-8 (as applicable) and FIRPTA certificate (Attachments 1A or 1B to the election form), to Mellon Investor Services, LLC, on or prior to     •    , 2007, the election deadline.


Representations and Warranties

        The company and the operating trust made customary representations and warranties in the merger agreement that are subject, in some cases, to specified exceptions and qualifications contained in the merger agreement or in the disclosure schedules delivered in connection therewith. These representations and warranties relate to, among other things:

87


88


        For the purposes of the merger agreement, "material adverse effect" means, with respect to the company, an effect, event, development or change that, individually or in the aggregate with all other effects, events, developments or changes, is materially adverse to the assets, business, results of operations or financial condition of the company, the company's subsidiaries and the company's joint ventures, taken as a whole.

        A "material adverse effect" will not have occurred, however, as a result of any effect, event, development or change arising out of or resulting from:

89


        Under the merger agreement, the mere fact of a decrease in the market price of the company's common shares will not, in and of itself, constitute a material adverse effect. However, any effect, event, development or change underlying such decrease will be considered in determining whether there has been a material adverse effect.

        The merger agreement also contains customary representations and warranties made by the buyer parties that are subject, in some cases, to specified exceptions and qualifications. The representations and warranties relate to, among other things:

90


        The representations and warranties of each of the parties to the merger agreement will expire upon the closing of the mergers.


Conduct of Our Business Pending the Mergers

        Under the merger agreement, the company has agreed that, subject to certain exceptions in the merger agreement and the disclosure schedules delivered in connection therewith, between May 28, 2007 and the company merger effective time, the company and the company's subsidiaries will:

        The company also has agreed that during the same time period, subject to certain exceptions as fully described in the merger agreement or unless Parent either gives its prior written consent or does not object within certain limited time periods from the date the company requests such consent, the company and the company's subsidiaries will not, among other things:

91


92


93


        In addition, under the merger agreement, in the event that a holder of the operating trust's Class A-1 common units exercises its redemption rights, the company will, if directed by Parent, exercise the company's right to elect to assume directly and satisfy such redemption right by paying to such holder of Class A-1 common units the cash amount or share amount due under the operating trust's organizational documents. The company will not, however, be required to take any action in contravention of any securities law or any historic, preexisting contractual obligation to satisfy any such redemption.

94



No Solicitation of Transactions

        The company has agreed that, from May 28, 2007 to the company merger effective time and subject to specified exceptions described below, the company and the company's subsidiaries will not, nor will any of us knowingly permit our respective representatives to:


        For purposes of the merger agreement, "acquisition proposal" means any proposal or offer (other than the mergers or any of the other transactions contemplated by the merger agreement, or any merger or similar transaction solely among the company and the company's subsidiaries, or among the company's subsidiaries) for any:


        Prior to the approval of the company merger by the company's shareholders, following the receipt of an unsolicited bona fide written acquisition proposal, if the company's board of trustees or a special committee of the company's board of trustees determines in good faith, after consultation with its legal

95


and financial advisors, that such acquisition proposal is, or is reasonably likely to lead to, a superior proposal, the company, the company's subsidiaries and the company's and their representatives may:

        For purposes of the merger agreement, "superior proposal" means a written acquisition proposal:

        The company and the operating trust have agreed to promptly notify Parent (but no more than 24 hours after initial receipt) of the company's receipt of any acquisition proposal, any request for information relating to the company or the company's subsidiaries, or any inquiry or request for discussions or negotiations regarding any acquisition proposal. In the company's notice to Parent, the company has agreed to provide a copy of such acquisition proposal and the identity of parties making the proposal. The company and the operating trust also have agreed to keep Parent informed on a prompt basis of the status of and any material developments regarding any such acquisition proposal (but no more than 24 hours after the occurrence of such development). Under the merger agreement, the company and the company's subsidiaries may not enter into any confidentiality agreement which prohibits the company from providing such information to Parent. The company also agreed to, and to cause each of the company's subsidiaries to, immediately cease any existing discussions, negotiations or communications with any parties regarding any acquisition proposal. The company also agreed to promptly request from each party who executed a confidentiality agreement that it return or destroy all confidential information previously furnished to such party. The company has made all such requests.

        The company also agreed not to take any action to exempt any person from the ownership restrictions in Article II of the company's declaration of trust or otherwise cause such restrictions not to apply unless such actions are taken in connection with a termination of the merger agreement.

96



        The company is obligated to call and hold a meeting of the company's shareholders for the purpose of voting upon the approval of the company merger and the other transactions contemplated by the merger agreement. In connection with such meeting, (a) the company's board of trustees will recommend to the company's shareholders to approve the company merger and the other transactions contemplated by the merger agreement, and (b) the company will use the company's reasonable best efforts to solicit or cause to be solicited from the company's shareholders proxies for such approvals and to take all other action necessary or advisable to secure the required vote of the company's shareholders. However, other than in connection with an acquisition proposal, the company's board of trustees or a special committee of the company's board may determine not to make, or may determine to change or withdraw its recommendation and not solicit such proxies from the company's shareholders or take such other necessary or advisable action in favor of the approval of the company merger and the other transactions contemplated by the merger agreement if, after consultation with its legal counsel, the company's board of trustees or a special committee of the company's board of trustees determines in good faith that the failure to take such actions would be inconsistent with its fiduciary duties under applicable law. However, unless the merger agreement is terminated in accordance with its terms, other than in connection with an acquisition proposal, the company is obligated to hold the shareholders' meeting notwithstanding that the company's board may have changed or withdrawn its recommendation. The operating trust has agreed to substantially similar provisions with respect to its unitholders' meeting, if deemed necessary by the parties.


Employee Benefits

        For a period of 12 months following the closing date, Parent has agreed that it will or will cause the surviving entity to provide all employees employed by the company or the company's U.S. subsidiaries (other than any such employees who are covered in collective bargaining or similar agreements) as of the company merger effective time and who continue to be employed by the surviving entity or its successors or assigns or any of their subsidiaries, which we refer to as "continuing employees" with (i) base salary in an amount at least equal to the base salary that was provided to such continuing employee immediately prior to the company merger effective time, and cash incentive compensation opportunities (excluding any payments related to equity or equity-based awards) in an attainable amount at least equal to the attainable amount that such continuing employee was eligible to receive immediately prior to the company merger effective time, and (ii) employee benefits (excluding the cash value of any equity-based award or benefits), that are no less favorable in the aggregate than those provided to such continuing employees immediately prior to the company merger effective time.

        However, neither Parent nor the surviving entity or their subsidiaries are obligated to issue or adopt any plans or arrangements providing for the issuance of shares of capital stock, warrants, options, stock appreciation rights or other rights in respect of any shares of capital stock of any entity or any securities convertible or exchangeable into such shares and none of the company's plans or arrangements providing for the issuance of these awards will be taken into account in determining whether employee benefits are no less favorable in the aggregate.

        Parent has also agreed to:

97



Pre-Closing Transactions

        Parent may request in its sole discretion and without the company's further consent, that, immediately prior to the closing, the company use commercially reasonable efforts to (a) convert any subsidiary organized as a corporation into a limited liability company (or other entity) or any subsidiary organized as a limited partnership or limited liability company into other entities, (b) sell the stock, shares of beneficial interest, partnership interests or limited liability interests owned by the company in any subsidiary at a price and on terms designated by Parent, and (c) sell any of the company's or the company's subsidiaries' assets at a price and on terms designated by Parent; provided that (i) the foregoing transactions will not delay or prevent completion of the mergers, (ii) the transactions will be implemented as close to the operating trust merger effective time as possible and the buyer parties have either waived or confirmed all conditions to the mergers have been satisfied, (iii) neither the company nor any of the company's subsidiaries is required to take any action that contravenes applicable law or the organizational documents of the company or any of the company's subsidiaries, (iv) any such actions or transactions would be contingent upon written confirmation from Parent confirming that the conditions to the obligations of each party and the buyer parties have been satisfied and the buyer parties are prepared to proceed immediately with the closing, (v) these actions (or the inability to complete them) will not affect or modify the obligations of the buyer parties under the merger agreement, (vi) neither the company nor any of the company's subsidiaries will be required to take any action that could adversely affect the company's classification as a REIT within the meaning of the Code, (vii) neither the company nor any of the company's subsidiaries will be required to take any action that would reasonably be expected to result in additional taxes being imposed on, or any adverse tax consequences to, any of the company's shareholders or other equity interest holders of the company which are incrementally greater than the consequences to such party in connection with the consummation of the mergers in the absence of such action unless such holders are indemnified by the buyer parties for such greater taxes, and (viii) neither the company nor any of the company's subsidiaries will be required to take any action that would reasonably be expected to trigger any liability under any tax protection agreement without the buyer parties first agreeing to pay such liability.

        Parent, upon the company's or the operating trusts' request, will advance or reimburse the company or the operating trust for all reasonable out-of-pocket costs to be incurred or incurred by us in connection with any of the actions described above. The buyer parties, jointly and severally, agreed to indemnify and hold the company, the company's subsidiaries and the company's and their representatives harmless from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments, and penalties suffered or incurred in connection with or as a result of taking such actions. None of the company's representations, warranties or covenants apply to, or could be deemed breached or violated by, any of such actions.


Agreement to Take Further Action

        Subject to the terms and conditions of the merger agreement and in accordance with applicable law, each party to the merger agreement has agreed to promptly make its respective filings, and any other required submissions, under any applicable antitrust or competition laws, and any other law with respect to the merger agreement and mergers. Further, each party has agreed to use its commercially reasonable efforts to take, or to cause to be taken, all appropriate actions and to do, or to cause to be done, all things necessary, proper or advisable under applicable law to consummate the mergers, and

98



the other transactions contemplated by the merger agreement, including using its commercially reasonable efforts to obtain all permits, consents, approvals, authorizations, qualifications and orders of governmental authorities as are necessary for the consummation of the transactions contemplated by the merger agreement and to fulfill the conditions to the mergers and the other transactions contemplated by the merger agreement as promptly as practicable.

        Each party to the merger agreement has agreed to cooperate and use its reasonable best efforts to defend through litigation on the merits any legal action, including administrative or judicial action, asserted by any party in order to avoid the entry of, or to have vacated, lifted, reversed, terminated or overturned any decree, judgment, injunction or other order that in whole or in part restricts, delays, prevents or prohibits consummation of the company merger, including by vigorously pursuing all available avenues of administrative and judicial appeal.

        Each party to the merger agreement has agreed to use its commercially reasonable efforts to obtain any third party consents necessary, proper or advisable to consummate the transactions contemplated by the merger agreement, disclosed in the merger agreement and disclosure schedules delivered in connection therewith, or required to prevent a material adverse effect from occurring prior to the company merger effective time. In the event that the company or the operating trust fails to obtain any required third party consent, the company and the operating trust have agreed to use the company's commercially reasonable efforts, and take such actions reasonably requested by Parent, to minimize any adverse effect upon the company, the operating trust and the buyer parties and their respective businesses resulting, or which could reasonably be expected to result, after the company merger effective time from the failure to obtain such consent.


Conditions to the Mergers

        Completion of the mergers depends upon the satisfaction or waiver of a number of conditions, including, among others:

        As a holder of approximately 89.3% of all of our outstanding common units, the company's approval is the only approval of the holders of our common units that is necessary under the merger agreement to approve the mergers and the other transactions contemplated by the merger agreement. This approval is expected to be effective 20 days after the date of this prospectus/information statement.

99



        The obligations of the buyer parties to complete the mergers are subject to the following additional conditions:

        The company's obligations and the obligations of the operating trust to complete the mergers are subject to the following additional conditions:

100


        For the purposes of the merger agreement, "Parent material adverse effect" means an event, circumstance, change or effect that could reasonably be expected to prevent or materially hinder or delay any of the buyer parties from consummating the mergers or the other transactions contemplated by the merger agreement.


Termination

        The merger agreement may be terminated and the mergers may be abandoned at any time prior to the operating trust merger effective time, as follows:

101


102



Termination Fee and Expenses

        The company has agreed to pay Parent a termination fee of $235.0 million or reimburse Parent up to $10.0 million for Parent's reasonable transaction expenses under certain circumstances. Parent has also agreed to reimburse the company for the company's reasonable transaction expenses in certain situations.

        The company has agreed to pay Parent the termination fee of $235.0 million if the merger agreement is terminated under the following circumstances:

        The company also has agreed to pay Parent the termination fee of $235.0 million, less any reimbursable transaction expenses previously paid to Parent, under the following circumstances:

103


        The merger agreement also provides that if either party terminates the merger agreement because of the other party's material breach of the merger agreement which would result in the failure of a condition being satisfied by December 31, 2007, the breaching party must reimburse the non-breaching party for its reasonable transaction expenses up to a limit of $10.0 million within three business days of the termination date.

        The company has agreed that in the event that the company fails to pay the termination fee or any termination expenses when due, or Parent fails to pay any termination expenses when due, the company or Parent, as the case may be, will reimburse the other party for all reasonable costs and expenses actually incurred or accrued by such party in connection with the collection under and enforcement of relevant provisions of the merger agreement.


Amendment and Waiver

        The merger agreement may be amended by mutual agreement of the parties in writing, whether before or after the company's shareholders have approved the merger agreement, provided that after any such shareholder approval, no amendment will be made which, by law or the rules of the New York Stock Exchange, requires further shareholder approval without first obtaining such shareholder approval. The merger agreement also provides that, at any time prior to the company merger effective time, the company and the operating trust, on the one hand, and the buyer parties, on the other hand, may extend the time for the performance of any obligations of the other party, waive any inaccuracy in the representations and warranties of the other party or waive compliance with any agreement or condition to its obligations contained in the merger agreement.

DESCRIPTION OF THE NEW DECLARATION OF TRUST OF ARCHSTONE-SMITH OPERATING
TRUST AFTER THE MERGERS

        The following is a summary of certain provisions of our new declaration of trust, which will be adopted in connection with the operating trust merger, and does not constitute a complete description of these matters. Class A-1 unitholders are urged to review the new declaration of trust carefully and consult with their own legal and tax counsel regarding the provisions of the new declaration of trust. The following discussion is qualified in its entirety by the terms of the new declaration of trust, the form of which is attached to and is a part of this prospectus/information statement as Annex B.

        We will not be permitted to pay any distributions on, or redeem or otherwise acquire, our common units unless all accumulated and unpaid distributions on all outstanding Series O preferred units through the then current distribution period (determined without regard to the cumulative amount of income allocated to the holders of Series O preferred units) and any other units of the operating trust ranking on par with Series O preferred units through the then-current distribution period have been paid in full or sufficient funds have been set apart for payment thereof and all amounts payable with respect to notices of redemption of Series O preferred units previously delivered to us have been paid in full or sufficient funds have been set aside for payment thereof.

        See "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Ranking" on page 117.


Archstone-Smith Operating Trust

        MergerCo will be the sole trustee of Archstone-Smith Operating Trust following the mergers. The number of trustees shall not be less than one nor more than fifteen. The term of office of each trustee shall be one year and until its successor is elected and qualifies, subject to prior death, resignation or removal.

        Our business and affairs shall be managed by MergerCo, which shall have the exclusive right and full authority and responsibility to manage and operate our business and to do all things it deems necessary or desirable to conduct our business. Similar to the existing declaration of trust, the new declaration of trust will not permit unitholders (other than MergerCo and its affiliates), including Series O preferred unitholders, to engage in the active management and control of our business. Our Series O preferred unitholders generally will not have any voting rights in respect of our business affairs other than with respect to the matters described under "Description of the Series O Preferred Units—Voting Rights" on page 113. MergerCo will control our management and operations and will determine, without the consent of Series O preferred unitholders, the terms of any transactions, our management policies and business objectives, including potential acquisitions and divestitures of a significant number of our properties and assets or interests in us and the distribution of cash and other property held by us.

        Following the effective time of the operating trust merger, TS Fund VII and Lehman Brothers and their affiliates will control, and can cause or prevent, any change in control of, or any extraordinary corporate transaction involving, the operating trust or the acquisition of any units of the operating trust that would be likely to result in a change in control of the operating trust or any of its subsidiaries.

        Unitholders are not personally or individually liable in any manner whatsoever for any debt, act, omission or obligation incurred by the trust or the trustee and shall be under no obligation to the trust

106


or its creditors with respect to their units other than the obligation to pay to the trust the full amount of the consideration for which the units were issued and certain tax withholding obligations.

        Our new declaration of trust will contain a provision authorizing our sole trustee, subject to any applicable terms of one or more classes or series of units, if any, and to the extent applicable, and subject to the terms of any existing applicable tax protection agreements, at its sole and absolute discretion, directly or indirectly, to cause us to acquire, sell, exchange, convey, contribute, mortgage, pledge, encumber, hypothecate, transfer or otherwise dispose of any or all of the operating trust's assets in a single transaction or a series of related transactions or cause us to merge or engage in any other combination transaction with or into any other person.

107



DESCRIPTION OF THE SERIES O PREFERRED UNITS

        Prior to the operating trust merger, we will establish the Series O preferred units to be issued in connection with the operating trust merger. The terms of the Series O preferred units will be set forth in a Designation of the Preferences, Redemption and Other Rights, Voting Powers, Restrictions, and Limitations as to Series O preferred units, which we refer to herein as the "designation." The following is a summary of the material terms of the Series O preferred units. This summary does not include all of the terms of the designation and should be read together with the form of designation, which is attached to and forms a part of this prospectus/information statement as Exhibit F to Annex B, and applicable Maryland law.


Distributions

        Our trustee will determine when, as and if any distributions are made by us to our preferred unitholders. Distributions of available cash, when, as and if made by us, are payable quarterly in arrears to the holders of Series O preferred units on a pro rata basis based on the number of Series O preferred units that each holder owns. Such distributions, when, as and if made by us, will be made in preference to all of our other unitholders, other than holders of any class or series of our preferred units ranking on par with or senior to the Series O preferred units, at a preferential rate of 6% per annum on the stated value of $60.75 per Series O preferred unit or, if less, the cumulative income allocable to holders of Series O preferred units from the time of the operating trust merger to the time of determination. The most recent quarterly distribution of $0.4525 per Class A-1 common unit would represent an approximately 3% annual distribution rate. This rate is subject to increase to 8% per annum at such time as we incur more than $10.0 million of new indebtedness (with certain exceptions) after which the ratio of our total debt (which includes for this purpose the total liquidation preference of the Series O preferred units and any other parity preferred units) to total asset value exceeds 0.85 to 1.0 and will remain at 8% per annum until such ratio is no longer greater than 0.85 to 1.0. As discussed more fully below under "—Debt to Assets Ratio Provisions," we will provide notice to the holders of the Series O preferred units of any incurrence of indebtedness in excess of this ratio. We refer to distributions accruing at this preferential rate (as it may be adjusted from time to time) as the "preferred return." No interest will be payable in respect of any distribution payment or payments on Series O preferred units which may be in arrears, but any amount of preferred return which is due but unpaid (determined at the stated distribution rate without regard to the allocated income limitation) will accumulate and compound quarterly.

        As set forth below under "—Allocations," all "book income" and "book gain" of the operating trust (including the "book income" and "book gain" resulting from any revaluation of the assets of the operating trust that would occur in connection with a redemption of Series O preferred units or a liquidation of the operating trust) will first be allocated to the Series O preferred units. This priority allocation of "book income" and "book gain" make it more likely, but not certain, that the cumulative amount of net income allocated to holders of Series O preferred units over the period that the units are outstanding will be sufficient to permit the payment of the full accrued distributions at the stated distribution rate upon a liquidation of the operating trust or a redemption of the Series O preferred units, if not before.

        While there are any Series O preferred units outstanding, we will not declare or pay or set apart for payment any distributions on any class or series ranking on par with the Series O preferred units for any period except as provided below, unless all accumulated and unpaid distributions on the Series O preferred units (determined by taking into account the cumulative amount of income allocated to the holders of the Series O preferred units) have been or contemporaneously are declared and paid or set aside for payment for all periods ending on or prior to the distribution payment date. When distributions on the Series O preferred units are not paid in full or a sum sufficient for such payment is not set apart, all distributions declared upon Series O preferred units and all distributions declared upon any other class or series of parity units shall be declared ratably in proportion to the respective

108



amounts of distributions accumulated and unpaid on the Series O preferred units and accumulated and unpaid on such parity units.

        While there are any Series O preferred units outstanding, no distributions shall be declared or paid or set apart for payment on any junior units for any period (other than distributions paid solely in shares of, or options, warrants or rights to subscribe for or purchase shares of, junior units), nor shall any junior units be redeemed, purchased or otherwise acquired by us (other than pursuant to an employee incentive or benefit plan) unless all accumulated and unpaid distributions (determined without regard to the cumulative amount of income allocated to the holders of the Series O preferred units) have been or contemporaneously are declared and paid or set apart for payment on the Series O preferred units and any class or series ranking on a parity with the Series O preferred units for all periods up to and including the then-current distribution period and all amounts payable with respect to any redemptions of the Series O preferred units for which notices of redemption have been delivered to us have been paid in full or set apart for payment on the redemption date.

        No distributions on the Series O preferred units will be authorized by the trustee or paid or set apart for payment if such a distribution would violate any of our agreements, including those related to indebtedness, or is prohibited by law. Holders of Series O preferred units are not entitled to any distribution in excess of the full, cumulative distributions described herein, and receipt of the liquidation preference (as defined below) upon redemption of their Series O preferred units for cash or upon our dissolution, liquidation and winding-up.


Liquidation Preference

        Upon voluntary or involuntary liquidation, dissolution and winding up of our affairs, prior to any distributions to holders of junior units, the holders of Series O preferred units will be entitled to receive a liquidation preference per Series O preferred unit of $60.75 plus all accumulated and unpaid distributions to the date of final distribution to such holders (determined by taking into account the cumulative amount of income allocated to the holders of the Series O preferred units), which we refer to in this prospectus/information statement as the "liquidation preference," but such holders shall not be entitled to any further payment. If there are insufficient funds to pay this amount, the distributable liquidation proceeds will be allocated in proportion to the full liquidating distributions to which the holders of Series O preferred units and any parity units would have been entitled. After payment of the full amount of liquidating distributions to which they are entitled, the holders of Series O preferred units will have their Series O preferred units deemed cancelled and will have no claim to any of our remaining assets.


Ranking

        The Series O preferred units will rank on par with the Series I, P, Q-1, and Q-2 preferred units and senior to all other units either in existence on the date of the merger agreement or issued after the date of the merger agreement with respect to distributions and upon dissolution, liquidation, or winding up. So long as there are Series O preferred units with at least $10.0 million in aggregate liquidation preference outstanding, we will not be entitled to issue any units ranking senior to or on par with the Series O preferred units without the approval of holders of at least 662/3% of the outstanding Series O preferred units. This requirement is subject to certain exceptions described below under "—Voting Rights."


Allocations

        Our "book income" and "book gain", if any, based upon the value of our assets at that time of the operating trust mergers, first will be allocated to the holders of the Series O preferred units for each year until the aggregate amount of "book income" and "book gain" allocated with respect to each

109



Series O preferred unit is equal to the cumulative accrued distributions payable with respect to that preferred unit from the time of the operating trust merger, whether or not such distributions in fact have been paid, plus any "book loss" previously allocated to the Series O preferred unit during that period.

        All of our remaining "book income" and "book gain", if any, will be allocated to the holders of the other units of beneficial interest in us. All our "book loss," if any, will be allocated to the holders of other units of beneficial interest in us until the capital accounts of such holders (as adjusted based upon the fair market value of our assets at the time of the operating trust merger) are reduced to zero. Our "book loss" next will be allocated to the holders of Series O preferred units until the capital accounts of such holders (which will be adjusted to $60.75 per Series O preferred unit at the time of the operating trust merger) are reduced to zero. Any of our remaining "book loss" shall be allocated to the trustee.

        In connection with any liquidation, dissolution or winding up of our affairs, or upon any redemption of any of our Series O preferred units, all of our unsold property will be revalued to its fair market value at such time and any positive adjustment shall be allocated as "book income" or "book gain" and any negative adjustment shall be allocated as a "book loss."

        For these purposes, our "book income," "book gain" and "book loss" will be computed based upon the fair market value of our assets at the time of the operating trust merger. To the extent that there is a difference between the fair market value of our assets at the time of the operating trust merger and our adjusted basis in those assets, that difference will be accounted for under principles similar to those set forth in Section 704(c) of the Code, which means that the taxable gain inherent in those assets at the time of the operating trust merger generally will be allocated among our unitholders (including the Series O preferred units) in the manner in which such taxable gain would have been allocated if it had been recognized by the operating trust immediately prior to the operating trust merger. Accordingly, even if there is no "book gain" that would be allocated to holders of Series O preferred units upon the sale by the operating trust of one or more of its assets, the holders of the Series O preferred units could be allocated significant amounts of gain for tax purposes as a results of such sales, without any distributions attributable to that taxable gain. See "Federal Income Tax Considerations—Treatment of Unitholders that Receive Series O Preferred Units—Tax Consequences of Continued Investment in Series O Preferred Units after the Operating Trust Merger, Including Recognition of Gain Attributable to Sales of Assets to be Undertaken in Connection with the Operating Trust Merger" on page 144.


Redemption Rights

        Beginning on the fifth anniversary of the closing date of the operating trust merger (or, prior to such date, upon the death of a holder of Series O preferred units, or, in the case of a unitholder that is a trust that is includible in the taxable estate of an individual, the death of such individual, the personal representative of such holder's estate or the trustee of such trust, as the case may be, and for the 120 days following such death upon 30 days written notice to us), or as described below under "—Debt to Assets Ratio Provisions," each holder of Series O preferred units shall have the right to require us to redeem some or all of the Series O preferred units held by such holder at a cash redemption price per Series O preferred unit equal to $60.75 plus all accumulated and unpaid distributions through the redemption date (determined by taking into account the cumulative amount of income allocated to the holders of the Series O preferred units). Our trustee may elect, unless expressly prohibited by the terms of any applicable tax protection or other agreement, to assume and pay the redemption amount to a holder of Series O preferred units in satisfaction of any redemption by such holder. Following such payment by the trustee, we shall have no right or obligation to pay any amount to the holder with

110


respect to such redemption, and we, the holder and the trustee shall treat the transaction for federal income tax purposes as a sale of the holder's Series O preferred units to the trustee. On the redemption date, upon redemption, redeeming holders of Series O preferred units will have no further rights in respect of the Series O preferred units redeemed (except to receive the amounts due upon redemption) and redeemed Series O preferred units will no longer be deemed to be outstanding. A holder that exercises its redemption right in respect of 100% of its units will no longer be our unitholder.

        A holder may exercise this redemption right from time to time but no more frequently than once in any twelve calendar month period, and may not exercise this redemption right for less than one thousand Series O preferred units unless such holder holds fewer than one thousand Series O preferred units, in which event the redeeming holder must redeem all Series O preferred units held by such holder (except that a redeeming holder that is an entity may, no more than once in any twelve calendar month period, exercise its redemption right for less than one thousand Series O preferred units without regard to whether it is exercising the redemption right for all Series O preferred units it holds as long as such holder is exercising on behalf of one or more of its equity owners in respect of 100% of such equity owners' interests in such holder).

        During any twelve calendar month period, we will not be required to redeem a total number of Series O preferred units in excess of one-third of the number of Series O preferred units issued in the operating trust merger. If we receive redemption notices for a number of Series O preferred units in excess of that limit, we will redeem Series O preferred units in the order that we receive the redemption notices, that is, on a "first received, first redeemed basis." Any Series O preferred units for which redemption is deferred will be redeemed on the first business day of the first calendar month in which the Series O preferred units could be redeemed without causing the annual limit to be exceeded.

        In the event the trustee (or its direct or indirect parent) is a REIT with publicly traded equity securities, the trustee shall have the right to amend the cash redemption right and other provisions of the designation as necessary to provide such public REIT the option, in lieu of paying the redemption price in cash, to issue an amount of publicly traded stock in such public REIT with a fair market value at the time of redemption, as determined by the trustee in good faith, equal to the redemption price to any redeeming holder if either (1) the common shares to be issued to such holder are registered with the SEC for resale by the redeeming holder or (2) the redeeming holder is granted customary resale registration rights with respect to such common shares.

        Commencing on the fifth anniversary of the operating trust merger, we will have the right to redeem all of the Series O preferred units then outstanding at a cash redemption price per Series O preferred unit equal to $60.75 plus all accumulated and unpaid distributions through the redemption date (determined without regard to the cumulative amount of income allocated to the holders of the Series O preferred units) and the applicable tax protection amount for each holder as discussed below. On the redemption date, upon redemption, holders of Series O preferred units will have no further rights in respect of the Series O preferred units redeemed (except to receive the amounts due upon redemption) and will no longer be our unitholders, and such holder's redeemed Series O preferred units will no longer be deemed to be outstanding.

        The tax protection amount with respect to a holder shall mean the lesser of:

111



Debt to Assets Ratio Provisions

        In the event that we or any of our subsidiaries incur more than $10.0 million of debt and, following such incurrence, the ratio of our total debt (which includes for this purpose the liquidation preferences of the Series O preferred units and any other parity preferred units) to total assets (as such terms are defined in the new declaration of trust) exceeds 0.85 to 1.0, the stated distribution rate on the Series O preferred units will increase to 8% per annum until such time as the ratio of total debt to total assets is less than or equal to 0.85 to 1.0. This provision does not apply with respect to the incurrence of additional debt under revolving credit facilities and lines of credit or refinanced debt.

        If any of the following events occurs prior to January 1, 2022, each holder of Series O preferred units will be entitled to request that we redeem such holder's Series O preferred units, without regard to the restrictions on exercising redemption rights after the fifth anniversary of the operating trust merger or on the amount of Series O preferred units we can be required to redeem in any twelve calendar month period, for an amount of cash equal to the redemption price plus the applicable tax protection amount (if any) payable to such holder pursuant to the applicable tax protection agreement (if any), by providing a notice of redemption to us and our trustee:

        The operating trust will provide notice to the holders of Series O preferred units of any incurrence of debt by it or any of its subsidiaries following which the ratio of total debt to total assets would be greater than 0.85 to 1.0, which notice shall include notice of any prior distributions with respect to any units made in contemplation of such incurrence of debt. The operating trust will not make any distributions with respect to any units if prior to, or after giving effect to, such distribution ratio of total debt to total assets would be greater than 0.85 to 1.0 unless it shall have provided to the holders of Series O preferred units notice of such distribution, at least 30 days prior to the declaration of such distribution, setting forth the amount thereof and the then existing ratio of total debt to total assets. The operating trust will not make any such distribution until it has first paid, or set apart for payment, the amounts payable with respect to all redemption notices received from holders of Series O preferred units electing to have their Series O preferred units redeemed.


Voting Rights

        Except as summarized below, the holders of Series O preferred units shall have no voting rights whatsoever on any matter relating to us, except as required by any non-waivable provision of the laws

of the State of Maryland. So long as Series O preferred units with at least $10.0 million in aggregate liquidation preference remain outstanding, the affirmative vote or consent of the holders of 662/3% of the Series O preferred units then outstanding will be required for us to amend, alter or repeal the provisions of our declaration of trust that specify the rights of the Series O preferred units, whether by merger or consolidation or otherwise, which we refer to as an "event," so as to:

        In addition, the approval of each holder of Series O preferred units adversely affected thereby shall be required for any amendment of the provisions of our new declaration of trust, as described under "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Amendment of Declaration of Trust—After Operating Trust Merger."

        Any amendment of the provisions of our declaration of trust that constitute the tax protection agreement for holders of Class A-1 common units issued in our 2001 merger with the Smith partnership will continue to require the approval of holders of 76% of the Series O preferred units issued in exchange for Class A-1 common units entitled to the benefit of those provisions.

        Notwithstanding the foregoing, the Series O preferred units shall not be entitled to vote in connection with the transactions described above if, at or prior to the time when the act is taken with respect to which such vote or approval would otherwise be required, all outstanding Series O preferred units shall have been redeemed or called for redemption upon proper notice as described above, and subject to the conditions and requirements of such redemption provisions, and sufficient funds shall have been deposited in trust to effect such redemption in accordance with such redemption provisions.

COMPARISON OF RIGHTS OF CLASS A-1 COMMON UNITHOLDERS
AND SERIES O PREFERRED UNITHOLDERS

        The following comparison of Class A-1 unitholders rights summarizes the material differences between certain provisions of our existing declaration of trust and the new declaration of trust that will become effective as a result of the operating trust merger, insofar as they affect our Class A-1 unitholders, relating to, among other things, capitalization, issuance of additional units, distributions, redemption rights, outside activities of each of the company and MergerCo, as our sole trustee before and after the company merger, respectively, tax protection, transfers of units, voting rights and indemnification. This comparison is intended to assist our Class A-1 unitholders in understanding how their ownership in us will be changed if they elect to receive Series O preferred units instead of cash in exchange for their existing Class A-1 common units in the operating trust merger. This comparison is a summary in nature and does not constitute a complete description of these matters. Class A-1 unitholders are urged to review the new declaration of trust carefully and consult with their own legal and tax counsel regarding the provisions of the new declaration of trust. The following discussion is qualified in its entirety by the terms of the new declaration of trust, the form of which is attached to and is a part of this prospectus/information statement as Annex B and our existing declaration of trust, as amended, which is included in our public filings available on the SEC's website. See "Where You Can Find Additional Information." When reading this comparison you should refer to each declaration of trust for complete information.


Capitalization

        Before operating trust merger.    As of July 12, 2007, the record date for the company's special meeting of shareholders, we had the following outstanding units:

Class A-1 Common Units   26,663,505

Class A-2 Common Units

 

222,732,017

Series I Preferred Units

 

500

Series M Preferred Units

 

1

Series N-1 Preferred Units

 

300

Series N-2 Preferred Units

 

700

        The company owns all of the Class A-2 common units and the Series I preferred units. Outside common unitholders (including Messrs. Gerardi, Kogod and Smith, each of whom is a trustee of the company) own the other outstanding units.

        After operating trust merger.    Following the operating trust merger, we will have the following classes and series of units: Class A-1 common units, Class A-2 common units and Series I, O, P, Q-1 and Q-2 preferred units. As described under the heading, "The Merger Agreement—Treatment of Operating Trust Units," in the operating trust merger, holders of our Class A-1 common units will be entitled to elect to receive cash or a Series O preferred unit in exchange for each Class A-1 common unit they hold. MergerCo, which will be our sole trustee after the mergers, will retain all of the outstanding Class A-1 common units and Class A-2 common units and Series I preferred units. We will issue Series O preferred units, on a one-for-one basis, to holders of Class A-1 common units who do not elect to receive cash or who make no election. We will issue Series P, Q-1, and Q-2 preferred units, on a one-for-one basis, in exchange for outstanding Series M, N-1, and N-2 preferred units, respectively.

114




Issuance of Additional Units

        Before operating trust merger.    We are authorized to issue additional units, including to the company and its affiliates. These units may be issued in one or more classes or in one or more series of any class, with designations, preferences, rights, powers and duties, as determined by the company as trustee, in its sole and absolute discretion without the approval of any unitholder, unless otherwise limited by the terms of a specific class or series of units.

        No common or preferred unit may be issued to the company unless:

        No person shall have any preemptive, preferential or other similar right with respect to (i) additional capital contributions or loans to us or (ii) issuance or sale of any units.

        After operating trust merger.    Subject to the limitations described below, MergerCo, as our sole trustee, may from time to time cause us to issue additional units, other than Series O preferred units, to MergerCo or persons other than MergerCo for the consideration and on the terms and conditions that MergerCo deems appropriate. These additional units may be issued in one or more classes, or one or more series of any of such classes. Subject to the limitations described below, these additional units may have such designations, preferences and relative, participating, optional or other special rights, powers and duties, including rights, powers and duties senior to other units, all as shall be determined by MergerCo in good faith, subject to Maryland law.

        Notwithstanding the foregoing, as long as Series O preferred units with at least $10.0 million in aggregate liquidation preference remain outstanding, the affirmative vote or consent of the holders of 662/3% of the Series O preferred units then outstanding will be required for us to (a) increase the number of Series O preferred units outstanding or issue additional Series O preferred units other than pursuant to the transactions contemplated by the merger agreement and other than pursuant to the terms of the Series Q-1 and Q-2 preferred units, or (b) issue any class or series of partnership interests senior to or on par with the Series O preferred units.

        No person shall have any preemptive, preferential or other similar right with respect to (i) additional capital contributions or loans to us or (ii) issuance or sale of any units.


Distributions

        Before operating trust merger.    Our declaration of trust provides for the distribution of an amount equal to 100% of available cash on at least a quarterly basis, when, as and if declared by the company board, out of funds legally available for the payment of distributions. "Available cash" means all of our cash revenues and funds plus any reduction in reserves and minus interest, principal and other debt payments, all cash expenditures, including capital expenditures, investments in any entity, including loans, and any additions to reserves and other adjustments, as determined by the company in its sole

115


discretion. We make distributions to all unitholders who are unitholders on the record date for the distribution in the following priority:

        Unless otherwise specifically provided for in the declaration of trust or a supplement to the declaration of trust, at the time a new class or series is created, no unit will be entitled to preferential distribution. Distributions paid with respect to Class A-1 and Class A-2 common units and Series M, N-1, and N-2 preferred units will generally not be prorated. A Class A-1 unitholder will not in any event receive a distribution of available cash with respect to a unit if the unitholder is entitled to receive a distribution out of that same available cash with respect to a company share for which that unit has been exchanged or redeemed.

        We make reasonable efforts, as we determine in our sole and absolute discretion and consistent with the company's qualification as a REIT, to distribute available cash:

        If the company is not publicly traded, we are required to make cash distributions with respect to Class A-1 and Class A-2 common units at least annually for each taxable year through 2021 in an aggregate amount that reflects at least 90% of our taxable income for that year allocable to the Class A-1 and Class A-2 common units. These distributions will be made not later than 60 days after the end of that year.

        After operating trust merger.    MergerCo will determine when and if we will make any distributions on our units following the operating trust merger. Distributions of our available cash, when, as and if made, will be payable quarterly in arrears to the holders of Series O preferred units on a pro rata basis based on the number of Series O preferred units that each holder owns, in preference to all other holders of our units (other than the Series I, P, Q-1 and Q-2 preferred units, which will rank equally in priority to the Series O preferred units with respect to distributions), at a preferential rate of 6% per annum or, if less, the cumulative income allocable to holders of Series O preferred units from the time of the operating trust merger to the time of determination (subject to increase to 8% per annum in certain circumstances described below under the heading "—Debt to Assets Ratio") on the stated value of $60.75 per Series O preferred unit. No interest will be payable in respect of any distribution payment or payments on Series O preferred units which may be in arrears but any amount of preferred return that is due but unpaid (determined at the stated distribution rate without regard to the allocated income limitation) will accumulate and compound quarterly.

116



        Holders of Series O preferred units will not be entitled to any distribution in excess of the full, cumulative distributions described herein, and receipt of the redemption price upon redemption of such units or the liquidation preference upon dissolution, liquidation and winding-up.


Liquidation Preference

        Before operating trust merger.    The Class A-1 unitholders are not entitled to any preference over any other class or series of our units upon our dissolution, liquidation, or winding up. Upon any such event, the Class A-1 unitholders will share, pro rata, together with the holders of Class A-2 common units and Series M, N-1, and N-2 preferred units, the proceeds of dissolution, liquidation, or winding up remaining after payment of our debts and satisfaction of the preferences of any class or series of our units entitled to a preference in dissolution, liquidation, or winding up over our common units.

        After operating trust merger.    Upon the voluntary or involuntary dissolution, liquidation and winding up of our affairs, prior to any distributions to holders of any class or series of our units that rank junior to the Series O preferred units (including the Class A-2 common units held by MergerCo), the holders of Series O preferred units will be entitled to receive the liquidation preference per Series O preferred unit of $60.75 plus all accumulated and unpaid distributions to the date of final distribution to such holders (determined by taking into account the cumulative amount of income allocated to the holders of the Series O preferred units), but such holders will not be entitled to any further payment. If the proceeds of any dissolution, liquidation, or winding up remaining after payment of our debts and satisfaction of the preferences of any class or series of our units ranking senior to the Series O preferred units are insufficient to pay the liquidation preference on all outstanding Series O preferred units and the liquidation preferences of the Series I, P, Q-1, and Q-2 preferred units and any other class or series ranking on par with the Series O preferred units, such remaining proceeds will be distributed among the holders of the Series O preferred units and any other class or series ranking on parity with the Series O preferred units ratably, based upon the amounts of their respective liquidation preferences.


Ranking

        Before operating trust merger.    The Class A-1 unitholders are not entitled to any preference over any other class or series of our units in payment of distributions or upon our dissolution, liquidation, or winding up. The Class A-1 common units rank on par with the Class A-2 common units and Series M, N-1, and N-2 preferred units rank on par with each other with respect to distributions and upon dissolution, liquidation, or winding up.

        After operating trust merger.    The Series O preferred units will rank on par with the Series I, P, Q-1, and Q-2 preferred units and senior to the Class A-2 common units with respect to distributions and upon dissolution, liquidation, or winding up. So long as there are Series O preferred units with at least $10.0 million in aggregate liquidation preference outstanding, we will not be entitled to issue any units ranking senior to or on par with the Series O preferred units without the approval of holders of at least 662/3% of the outstanding Series O preferred units. This requirement is subject to certain exceptions described below under "—Other Voting Rights."


Conversion; Redemption

        Before operating trust merger.    Except as provided below, each holder of Class A-1 common units has the right to require us to redeem the holder's Class A-1 common units for either cash or, at the election of the company, the company common shares. As a general rule, a Class A-1 unitholder may exercise the redemption right at any time beginning on the first anniversary of the issuance of the units held by the Class A-1 unitholder. The company may agree to a shorter waiting period, or no waiting period, on the exercise of the unit redemption right.

117


        If the company gives the Class A-1 unitholders notice of its intention to make an extraordinary distribution of cash or property to its shareholders or effect a merger, a sale of all or substantially all of its assets, or any other similar extraordinary transaction, each Class A-1 unitholder may exercise its unit redemption right, regardless of the length of time it has held its Class A-1 common units. This redemption right begins on the date when the notice is given, which must be at least 20 business days before the record date for determining shareholders eligible to receive the distribution or to vote upon the approval of the merger, sale or other extraordinary transaction, and ends on the record date. The company provided a notice regarding the company merger on June 8, 2007 and the record date for the shareholder meeting was set at July 12, 2007.

        A Class A-1 unitholder may exercise its unit redemption right by giving written notice to us and the company. The Class A-1 common units specified in the notice shall be redeemed on the 10th business day following the date the company received the redemption notice or, in the case of the exercise of a unit redemption right in connection with an extraordinary transaction, the date we and the company received the redemption notice.

        A notice of redemption delivered to us, with a copy to the company, will serve to exercise the redemption right. A Class A-1 unitholder may not exercise the redemption right for fewer than 1,000 Class A-1 common units, or if the Class A-1 unitholder holds fewer than 1,000 Class A-1 common units, all of the Class A-1 common units held by that Class A-1 unitholder. The redeeming Class A-1 unitholder will have no right to receive any distributions paid on or after the redemption date with respect to those units redeemed.

        Unless the company elects to assume and perform our obligation with respect to the unit redemption right, as described below, a Class A-1 unitholder exercising a unit redemption right will receive cash from us in an amount equal to the market value of the company common shares for which the Class A-1 common units to be redeemed are redeemable. The market value of a company common share for this purpose will be equal to the average of the closing trading price of a company common share on the NYSE for the ten trading days before the day on which the redemption notice was received by the company.

        Instead of us acquiring the units being redeemed for cash, the company has the right to elect to acquire on the redemption date the Class A-1 common units directly from a Class A-1 unitholder exercising the unit redemption right in exchange for either cash in the amount specified above or a number of company common shares equal to the number of Class A-1 common units offered for redemption, adjusted as specified in the declaration of trust of the company to take into account prior share dividends or any subdivisions or combinations of the company common shares. No redemption or exchange can occur if delivery of common shares by the company would be prohibited either under the provisions of the company's declaration of trust or under applicable federal or state securities laws, in each case regardless of whether the company would in fact elect to assume and satisfy the unit redemption right.

        Unless the company exercises its right to purchase the redeeming Class A-1 unitholder's units, as described above, the company has no obligation to the redeeming Class A-1 unitholder with respect to the redeeming Class A-1 unitholder's unit redemption right. Likewise, if the company exercises this purchase option, we have no obligation to pay any amount to the redeeming Class A-1 unitholder with respect to the unit redemption right. If the company elects to assume and perform our obligations under the unit redemption right, each of the redeeming Class A-1 unitholder, the company, and us will treat this transaction between the company and the redeeming Class A-1 unitholder, for federal tax purposes, as a sale of the redeeming Class A-1 unitholder's units to the company.

        All Class A-1 common units delivered for redemption must be delivered to the company free and clear of all liens.

118



        After operating trust merger.    The Series O preferred units will be redeemable as described below.

119



Debt to Assets Ratio Provisions

        Before operating trust merger.    The operating trust declaration of trust does not contain any limitation on our ability to incur debt.

        After operating trust merger.    In the event that we or any of our subsidiaries incur more than $10.0 million of debt (with certain exceptions described under "Description of Series O Preferred Units—Debt to Assets Ratio Provisions") and, following such incurrence, the ratio of our total debt (which includes for this purpose the total liquidation preference of the Series O preferred units and any other parity preferred units) to total assets exceeds 0.85 to 1.0, the distribution rate on the Series O preferred units will increase to 8% per annum until such time as the ratio of total debt to total assets is less than or equal to 0.85 to 1.0.

        If any of the following events occurs prior to January 1, 2022, each Series O preferred unitholder will be entitled to request that we redeem such holder's Series O preferred units, without regard to the restrictions on exercising after the fifth anniversary of the operating trust merger and on the amount of Series O preferred units we can be required to redeem in any twelve calendar month period, for an amount of cash equal to the redemption price plus the applicable tax protection amount (if any) payable to such holder pursuant to the applicable tax protection agreement (if any), by providing a notice of redemption to us and our trustee:


Sale of Substantially All of Our Assets

        Before operating trust merger.    A sale, exchange, transfer or other disposition of all or substantially all of our assets in a single transaction or a series of related transactions, including by way of a merger, consolidation or other combination of us with another entity, will require the following:


        After the operating trust merger.    Subject to any applicable terms of one or more classes or series of units, if any, and to the extent applicable, and subject to the terms of any existing applicable tax protection agreements, MergerCo may, at its sole and absolute discretion, directly or indirectly, cause the operating trust to acquire, sell, exchange, convey, contribute, mortgage, pledge, encumber,

120


hypothecate, transfer or otherwise dispose of any or all of the operating trust's assets in a single transaction or a series of related transactions (including by way of merger (including a triangular merger), or other combination with any other person).


Amendment of Declaration of Trust

        Before operating trust merger.    In general, our declaration of trust may be amended only with the approval of the company and unitholders holding a majority of the common units entitled to vote thereon. However, after the company has declared an amendment advisable, the holders of a majority of the Class A-2 common units have the power, without the consent of the other unitholders, to amend our declaration of trust as may be required:

        The approval of the holders of at least a majority of the Class A-1 common units is necessary to amend provisions regarding, among other things:

        Our declaration of trust may not be amended with respect to any unitholder adversely affected by the amendment without the consent of that unitholder if the amendment would, among other things:

121


        Any amendment of the provisions of our declaration of trust that constitute the tax protection agreement for holders of Class A-1 common units issued in our 2001 merger with Charles E. Smith Residential Realty, L.P., which we refer to as "the Smith partnership," require the approval of holders of 76% of the Class A-1 common units entitled to the benefit of those provisions.

        After the operating trust merger.    In general, our declaration of trust may be amended only with the approval of the trustee and unitholders holding a majority of the units then outstanding and entitled to vote thereon. However, the trustees may, by a two-thirds vote and without the approval of unitholders, amend the declaration of trust to enable the trust to qualify as a real estate investment trust under Maryland law, and may, by a majority vote of the entire board and without the approval of unitholders, amend the declaration of trust in any way in which the charter of a corporation may be amended in accordance with Section 2-605 of the MGCL.

        After the trustee has declared an amendment advisable, the holders of a majority of the Class A-2 common units have the power, without the consent of other unitholders, to amend the declaration of trust in the same way they were empowered to do so before the merger.

        As before the merger, our declaration of trust may not be amended with respect to any unitholder adversely affected by the amendment without the consent of that unitholder, if the amendment would, among other things:

122


        Any amendment of the provisions of our declaration of trust that constitute the tax protection agreement for holders of Class A-1 common units issued in our 2001 merger with Charles E. Smith Residential Realty, L.P., which we refer to as "the Smith partnership," would require the approval of holders of 76% of the Class A-1 common units entitled to the benefit of those provisions.


Other Voting Rights

        Before operating trust merger.    Class A-1 unitholders and Class A-2 unitholders have exclusive rights to vote together as a single class on all matters requiring the approval of our unitholders, except as otherwise provided by our declaration of trust or applicable Maryland law. Our declaration of trust provides that certain matters, including the election of trustees and certain amendments to our declaration of trust, may be approved by holders of our Class A-2 common units. Certain other matters, including certain amendments to our declaration of trust and certain mergers involving us or the company and certain sales of all or substantially all of our assets or the company's assets, require the approval of the holders of a majority of the Class A-1 common units voting as a separate class. These matters are summarized under the headings "—Amendment of Declaration of Trust" and "—Sale of Substantially All of Our Assets."

        After the operating trust merger.    Except as summarized below, the holders of Series O preferred units will have no voting rights whatsoever on any matter relating to us, except as required by any non-waivable provision of Maryland law.

        So long as Series O preferred units with at least $10.0 million in aggregate liquidation preference remain outstanding, the affirmative vote or consent of the holders of 662/3% of the Series O preferred units then outstanding will be required for us to amend, alter or repeal the provisions of our declaration of trust that specify the rights of the Series O preferred units, whether by merger or consolidation or otherwise, which we refer to as an "event," so as to:

        In addition, the approval of each holder of Series O preferred units adversely affected thereby shall be required for any amendment of the provisions of our new declaration of trust, as described above under "—Amendment of Declaration of Trust—After Operating Trust merger."

123


        Any amendment of the provisions of our declaration of trust that constitute the tax protection agreement for holders of Class A-1 common units issued in our 2001 merger with the Smith partnership will continue to require the approval of holders of 76% of the Series O preferred units issued in exchange for Class A-1 common units entitled to the benefit of those provisions.

        Notwithstanding the foregoing, the Series O preferred units shall not be entitled to vote in connection with the transactions described above if, at or prior to the time when the act is taken with respect to which such vote or approval would otherwise be required, all outstanding Series O preferred units shall have been redeemed or called for redemption upon proper notice as described above, and subject to the conditions and requirements of such redemption provisions, and sufficient funds shall have been deposited in trust to effect such redemption in accordance with such redemption provisions.


Meetings

        Before operating trust merger.    There will be an annual meeting of unitholders at a time and place as the company shall prescribe, at which trustees may be elected and any other proper business may be conducted. The annual meeting of unitholders will be held upon reasonable notice at a convenient location and within a reasonable period following delivery of the annual report. Special meetings of unitholders may be called by us or by our chairman of the board, president or chief financial officer, and must be called upon the written request of unitholders holding in the aggregate 25% or more of our outstanding units entitled to vote. Written notice stating the place, date and time of the unitholders' meeting and, in the case of a special meeting, the purpose or purposes for which the meeting is called, must be delivered not less than 10 nor more than 60 days before the day of the meeting either personally or by mail to each unitholder of record entitled to vote at the meeting. Unitholders not entitled to vote at a meeting will not have any rights to notice of a meeting, except as expressly provided for in our declaration of trust or under law. No other business than that which is stated in the call for a special meeting will be considered at the meeting.

        Only Class A-2 unitholders have the right to vote in the election of trustees. Exclusive voting power is vested in the common units, except to the extent that our declaration of trust or Maryland law provides voting rights to any other class of units.

        After the operating trust merger.    No material change, except that special meetings of unitholders may not be called upon the written request of unitholders holding in the aggregate 25% or more of outstanding units entitled to vote.


Tax Protection Indemnification

        Before operating trust merger.    In our 2001 merger with the Smith partnership we agreed, for the benefit of the holders of the Smith partnership units that were converted into our Class A-1 common units in that merger, not to sell, exchange or otherwise dispose of, except in tax-free or tax-deferred transactions, any of the properties that were held by the Smith partnership or any interest therein. These restrictions, which are included in a tax protection agreement that is part of our declaration of trust, are effective until January 1, 2022. In addition, we agreed to maintain specified levels of borrowings outstanding with respect to the Smith partnership properties for the same period, and have made other specified undertakings. If we sell any of the Smith partnership properties or any interest therein without satisfaction of certain conditions, engage in any merger that requires that the former holders of Smith partnership units who now hold our Class A-1 common units recognize all or part of the gain that would be recognized by them for tax purposes upon a sale of any one or more of the Smith partnership properties, or repay borrowings relating to the Smith partnership properties, we may be liable for monetary damages for engaging in these actions. In addition, in the Smith partnership merger, we assumed the obligations of the Smith partnership under certain then existing tax protection agreements in favor of various holders of Smith partnership units.

124


        In connection with other acquisitions of properties in exchange for our units, we have entered into tax protection agreements with the contributing parties that acquired our units in such transactions. These agreements, which have differing terms, generally afford various protections to the holders of such units in connection with sales of the properties they contributed, or interests therein, transactions treated as sales of such properties for federal income tax purposes, debt refinancings, and certain other matters.

        After the operating trust merger.    Following the operating trust merger, we will continue to be obligated under all tax protection agreements that have not expired to those holders of our Series O preferred units who are the beneficiaries of such agreements and who do not elect to receive cash in the operating trust merger in exchange for their Class A-1 common units, but only with respect to those Class A-1 common units for which such holders have not elected to receive the cash consideration.


Management

        Before operating trust merger.    Except as otherwise expressly provided in our declaration of trust, our business and affairs are managed by the company, which has the exclusive right and full authority and responsibility to manage and operate our business. Class A-1 unitholders do not have any right to participate in or exercise control or management power over our business and affairs or the power to sign documents for or otherwise bind us. The company has full power and authority to do all things it deems necessary or desirable to conduct our business, as described below. In particular, the company may, but is under no obligation to, consider the tax consequences to other unitholders when making decisions on our behalf. The unitholders, other than the Class A-2 common unitholders (which are held by the company), have no power to remove the company or any other trustee. The company and any other trustee, however, may not take any action that is contrary to an express limitation or prohibition in our declaration of trust without an amendment to that provision adopted under our declaration of trust.

        In addition, the consent of the unitholders to some matters is necessary in limited circumstances, as described below.

        After operating trust merger.    Our business and affairs shall be managed by MergerCo, which shall have the exclusive right and full authority and responsibility to manage and operate our business and to do all things it deems necessary or desirable to conduct our business. Similar to the existing declaration of trust, the new declaration of trust will not permit unitholders (other than MergerCo and its affiliates), including Series O preferred unitholders, to engage in the active management and control of our business. Our Series O preferred unitholders generally will not have any voting rights in respect of our business affairs other than with respect to the matters described under "Description of the Series O Preferred Units—Voting Rights." MergerCo will control our management and operations and will determine, without the consent of Series O preferred unitholders, the terms of any transactions, our management policies and business objectives, including potential acquisitions and divestitures of a significant number of our properties and assets or interests in us and the distribution of cash and other property held by us.


Outside Activities of Sole Trustee

        Before operating trust merger.    Without the approval of the holders of at least a majority of the Class A-1 common units outstanding and entitled to vote thereon, the company is generally prohibited from, directly or indirectly, entering into or conducting any business other than in connection with the ownership, acquisition and disposition of our units and the management of our business and such activities as are incidental thereto. Without the approval of the holders of at least a majority of the Class A-1 common units outstanding and entitled to vote thereon, the assets of the company shall be

125


limited to our units and permitted debt obligations issued by us, so that the company's shares and our corresponding units will be completely fungible except as otherwise specifically provided in our declaration of trust. In addition, the company is generally prohibited from issuing any new equity securities unless it contributes the proceeds of such issuance to us in exchange for securities with comparable rights and is prohibited from incurring debt unless it loans the proceeds thereof to us.

        After the operating trust merger.    Except as expressly prohibited by the new declaration of trust, the company and any officer, director, employee, agent, trustee, affiliate or shareholder of the company shall be entitled to and may have business interests and engage in business activities in addition to those relating to the operating trust, including business interests and activities that are in direct competition with the operating trust or that are enhanced by the activities of the operating trust. In addition, the company and any of its affiliates may acquire units and shall be entitled to exercise all rights of a unitholder relating to such units. If the trust or the company acquires shares as a result of the forfeiture of such shares, then the company shall cause the trust to cancel that number of units equal to the number of shares so acquired and the trust will transfer any such shares to the trustee for cancellation. The company may issue additional shares if certain conditions are met, and may incur a funding debt, including, without limitation, a funding debt that is convertible into shares or otherwise constitutes a class of new securities, subject to the condition that the trustee lend to the trust the net proceeds of such funding debt.


Transactions with Affiliates

        Before operating trust merger.    Except as expressly permitted by our declaration of trust, we are not permitted to, directly or indirectly, sell, transfer or convey any property to, or purchase any property from, or borrow funds from, or lend funds to, any unitholder (other than the company) or any of our affiliates or the company's affiliates that is not also one of our subsidiaries, except pursuant to transactions that are determined by the company in good faith, which determination shall be conclusive, to be on terms that are fair and reasonable and no less favorable to us than would be obtained from an unaffiliated third party or that comply with the provisions of the Maryland General Corporation Law that apply to interested director transactions.

        After the operating trust merger.    The operating trust may, directly or indirectly, sell, transfer or convey any property to, or purchase any property from, or borrow funds from, or lend funds to, any unitholder or any affiliate of the operating trust or MergerCo, subject to Maryland Law.


Transfers

        Before operating trust merger.    The company generally may not transfer any of its units or withdraw as trustee, except in connection with a merger, consolidation or other combination with or into another entity, a sale of all or substantially all of its assets or any reclassification, recapitalization or change of its outstanding shares, other than a change in the par value of its shares. The company may engage in such a transaction only if:

126


        A unitholder may transfer, with or without the consent of the company, all or any portion of its units or rights as a unitholder:

        No other transfers may be made without the prior written consent of the company, which consent may be withheld in its sole and absolute discretion.

        The company may prohibit any transfer of units by a unitholder unless it receives a written opinion of legal counsel, with the opinion and counsel being reasonably satisfactory to the company, that the transfer would not require filing of a registration statement under the Securities Act or would not otherwise violate any federal, or state securities laws or regulations applicable to us or the transfer of the units. Further, no transfer of units by a unitholder may be made if, in the opinion of our legal counsel:

        In the case of a proposed transfer of units to one of our lenders or any person related to the lender whose loan constitutes a nonrecourse liability, the transferring unitholder must obtain the consent of the company.

        After the operating trust merger.    MergerCo generally may transfer and assign any of its units or withdraw as the trustee, except that in connection with a merger, consolidation or other combination with or into another entity, a sale of all or substantially all of its assets or any reclassification,

127



recapitalization or change of its outstanding shares, other than a change in the par value of its share. MergerCo may engage in such a transaction only if:

        A unitholder may transfer, with or without the consent of the trustee, all or any portion of its units or rights as a unitholder:

        Units in the operating trust shall be transferable only in accordance with the provisions of their respective terms. In general, Series O preferred units are transferable without the prior written consent of the trustee. With respect to Series P preferred units and Series Q preferred units, no transfers, other than the transfers described above, may be made without the prior written consent of the trustee, which consent may be withheld in its sole and absolute discretion.

        In addition, our trustee may prohibit any transfer of units by a unitholder unless it receives a written opinion of legal counsel, with the opinion and counsel being reasonably satisfactory to the trustee, that the transfer would not require filing of a registration statement under the Securities Act or would not otherwise violate any federal, or state securities laws or regulations applicable to us or the transfer of the units. Further, no transfer of units by a unitholder may be made if, in the opinion of our legal counsel:

        In the case of a proposed transfer of units to one of our lenders or any person related to the lender whose loan constitutes a nonrecourse liability, the transferring unitholder must obtain the consent of MergerCo.

128




Indemnification of Trustee and Certain Related Persons

        Before operating trust merger.    We will indemnify, to the fullest extent provided by law, any person or entity made a party to a proceeding by reason of its status as a unitholder or a trustee, director or officer of the company or us and any other persons or entities as the company may designate, in its sole discretion, from and against any and all losses, claims, damages, liabilities, joint or several, and expenses. Expenses include, without limitation, attorneys' fees and other legal fees and expenses, judgments, fines, settlements and other amounts arising from or in connection with any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, incurred by the indemnitee and relating to the company or us or the operation of, or the ownership of property by, either the company or us, as described in our declaration of trust, in which the indemnitee may be involved, or is threatened to be involved, as a party or otherwise, unless it is established by a final determination of a court of competent jurisdiction that:

        Any indemnification will be made only out of our assets and any insurance proceeds from the liability policy covering the company or us. Indemnitees, the company, and limited partners will have no obligation to contribute to our capital or otherwise provide funds to enable us to fund our indemnity obligations.

        We may advance amounts to an indemnitee for expenses upon receipt of:

        These indemnification rights are in addition to any other rights afforded to an indemnitee under any other agreement, by vote of the unitholders, under applicable law or otherwise. These rights will continue as to an indemnitee who has ceased to serve unless otherwise provided in a written agreement under which indemnitees are indemnified. We are authorized to purchase and maintain insurance on behalf of the indemnitees with respect to the foregoing matters.

        An indemnitee will not be denied indemnification in whole or in part because the indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of our declaration of trust.

        After the operating trust merger.    No material change.


Financial Statements and Reports

        Before operating trust merger.    On or before the date on which the company mails its annual report to its shareholders, the company is required to use commercially reasonable efforts to cause to be mailed to each unitholder an annual report, as of the close of our most recently ended fiscal year, containing our financial statements, or financial statements of the company if the company statements are prepared solely on a consolidated basis with us, for that fiscal year.

        In addition, if the company mails quarterly reports to its shareholders, the company is required to mail to each unitholder a report containing our unaudited financial statements, as of the last day of the calendar quarter, or financial statements of the company if the company statements are prepared solely on a consolidated basis with us.

129



        We currently are required to file quarterly, annual, and other periodic reports with the SEC, which are publicly available.

        After the operating trust merger.    We are not required to provide the unitholders with any reports but currently are required as a registrant to file quarterly, annual, and other periodic reports with the SEC, which are publicly available. See also "Risk Factors—Risks Related to the Series O Preferred Units and Our Structure After the Mergers—The termination of registration of our Class A-1 common units under the Exchange Act would substantially reduce the information required to be publicly furnished by us and would make certain provisions of the Exchange Act no longer applicable to us" on page 37.

COMPARISON OF PREFERRED UNITHOLDERS RIGHTS

        The following comparisons of preferred unitholders rights summarize the material differences between certain provisions of our existing declaration of trust and the new declaration of trust that will become effective as a result of the operating trust merger, insofar as they affect our Series M, N-1, and N-2 preferred unitholders, relating to, among other things, distributions, liquidation preference, redemption rights, ranking, and voting rights. This comparison is summary in nature and does not constitute a complete description of these matters. Series M, N-1, and N-2 preferred unitholders are urged to review the new declaration of trust carefully and consult with their own legal and tax counsel regarding the provisions of the new declaration of trust, particularly the provisions relating to the Series P, Q-1, and Q-2 preferred units, respectively. The following discussion is qualified in its entirety by the terms of the new declaration of trust, the form of which is attached to and is a part of this prospectus/information statement as Annex B and our existing declaration of trust, as amended, which is included in our public filings available on the SEC's website. See "Where You Can Find Additional Information." When reading this comparison you should refer to each declaration of trust for complete information.


Series M Preferred Unit

        Before operating trust merger.    The holder of the Series M preferred unit currently is entitled to receive distributions when, as, and if paid on the Class A-1 common units, in an amount equivalent to the distributions paid on a number of Class B common units equal to $10,000 divided by the price of our common shares on December 10, 2004, which we refer to as the "underlying common unit amount." After the redemption price determination time (as defined in the Contribution Agreement dated as of December 13, 2004 between us and Ezra Mersey relating to a multifamily project to be developed in San Francisco), the amount of distributions will be equivalent to the distributions payable on a number of Class B common units equal to the sum of (x) the underlying common unit amount plus (y) a number of Class B common units with an aggregate value as of the date of determination of the redemption price equal to the redemption price of the Series M preferred unit (calculated as described below) (such total number of Class B common units described in (x) and (y) being referred to as the "Series M redemption unit amount").

        After operating trust merger.    The holder of the Series P preferred unit initially will be entitled to receive distributions when, as, and if paid on the Series O preferred units, in an amount equivalent to the distributions paid on 263 Series O preferred units, which we refer to as the "underlying preferred unit amount." After the redemption price determination time, the amount of distributions will be equivalent to the distributions payable on a number of Series O preferred units equal to the sum of (x) the underlying the preferred unit amount plus (y) a number of Series O preferred units with an aggregate stated value as of the date of determination of the redemption price equal to the redemption price of the Series P preferred unit (calculated as described below) (such total number of Series O preferred units described in (x) and (y) being referred to as the "Series P redemption unit amount").

        Before operating trust merger.    The Series M preferred unitholder is not entitled to any preference over any other class or series of our units upon our dissolution, liquidation, or winding up. Upon any such event, the Series M preferred unitholder will share, pro rata, together with the holders of Class A-1 and A-2 common units and Series N-1 and N-2 preferred units, the proceeds of dissolution, liquidation, or winding up remaining after payment of our debts and satisfaction of the preferences of any class or series of our units entitled to a preference in dissolution, liquidation, or winding up over our common units. The Series M unitholder will be entitled to receive a liquidating distribution equal to the amount it would receive if it held a number of Class B common units equal to the underlying

131


common unit amount or, after the date of determination of the redemption price, a number of Class B common units equal to the Series M redemption unit amount.

        After operating trust merger.    Upon the voluntary or involuntary dissolution, liquidation and winding up of our affairs, prior to any distributions to holders of any class or series of our units that rank junior to the Series P preferred unit (including the Class A-2 common units held by MergerCo), the holder of the Series P preferred unit will be entitled to receive a liquidating distribution equal to the amount it would receive if it held 263 Series O preferred units equal to the underlying preferred unit amount or, after the date of determination of the redemption price, a number of Series O preferred units equal to the Series P redemption unit amount.

        Before operating trust merger.    The Series M preferred unitholder is not entitled to any preference over any other class or series of our units in payment of distributions or upon our dissolution, liquidation, or winding up. The Series M preferred unit ranks on par with the Class A-1 and A-2 common units and the Series N-1 and N-2 preferred units with respect to distributions and upon dissolution, liquidation, or winding up.

        After operating trust merger.    The Series P preferred unit will rank on par with the Series I, O, Q-1, and Q-2 preferred units and senior to the Class A-2 common units with respect to distributions and upon dissolution, liquidation, or winding up.

        Before operating trust merger.    From and after the redemption price determination time, the holder of the Series M preferred unit will have the right to have the Series M preferred unit redeemed, in whole and not in part, in the same manner and for the same consideration as if the holder held a number of Class B common units equal to the Series M redemption unit amount and such Class B common units were automatically convertible into Class A-1 common units and there were no one-year waiting period for the redemption. The current provisions of our declaration of trust relating to the redemption of Class A-1 common units are described under "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Conversion; Redemption—Before Operating Trust Merger."

        After operating trust merger.    From and after the redemption price determination time, the holder of the Series P preferred unit will have the right to have the Series P preferred unit redeemed, in whole and not in part, in the same manner and for the same consideration as if the holder held a number of Series O preferred units equal to the Series P redemption unit amount, as described under "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Conversion; Redemption—After Operating Trust Merger," without regard to the five-year waiting period for redemption of Series O preferred units.

        Before operating trust merger.    The holder of the Series M preferred unit does not have any voting rights or right to consent to any matter requiring the consent or approval of our unitholders, except as required by law and other than, as provided in the declaration of trust, certain approval rights regarding amendments to the terms of the Series M preferred unit that are materially adverse to the rights or preferences of the Series M preferred unit. See "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Amendment of Declaration of Trust" beginning on page 121.

132


        After the operating trust merger.    The holder of the Series P preferred unit does not have any voting rights or right to consent to any matter requiring the consent or approval of our unitholders, except as required by law and except that the approval of the holder of the Series P preferred unit will be required for any amendment of the provisions of our new declaration of trust that require the approval of all adversely affected unitholders, as described above under "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Amendment of Declaration of Trust—After Operating Trust Merger," and to the extent any such amendment is applicable to the holder of the Series P preferred unit and such holder is adversely affected.


Series N-1 and N-2 Preferred Units

        Before operating trust merger.    The holder of the Series N-1 preferred units is entitled to receive distributions when, as, and if paid on the Class A-1 common units, in an amount equivalent to the distributions paid on 11.58 Class A-1 common units for each Series N-1 preferred unit. The holder of the Series N-2 preferred units is entitled to receive distributions when, as, and if paid on the Class A-1 common units, in an amount equivalent to the distributions paid on 4.96 Class A-1 common units for each Series N-2 preferred unit.

        After operating trust merger.    The holder of the Series Q-1 preferred units is entitled to receive distributions when, as, and if paid on the Series O preferred units, in an amount equivalent to the distributions paid on 11.58 Series O preferred units. The holder of the Series Q-2 preferred units is entitled to receive distributions when, as, and if paid on the Class A-1 common units, in an amount equivalent to the distributions paid on 4.96 Series O preferred units.

        Before operating trust merger.    The Series N-1 and N-2 preferred unitholders are not entitled to any preference over any other class or series of our units upon our dissolution, liquidation, or winding up. Upon any such event, the Series N-1 and N-2 preferred unitholders will share, pro rata, together with the holders of Class A-1 and A-2 common units and Series M preferred unit, the proceeds of dissolution, liquidation, or winding up remaining after payment of our debts and satisfaction of the preferences of any class or series of our units entitled to a preference in dissolution, liquidation, or winding up over our common units. The Series N-1 preferred unitholder will be entitled to receive a liquidating distribution equal to the amount it would receive if it held 11.58 Class A-1 common units for each Series N-1 preferred unit and the Series N-2 preferred unitholder will be entitled to receive a liquidating distribution equal to the amount it would receive if it held 4.96 Class A-1 common units for each Series N-2 preferred unit.

        After operating trust merger.    Upon the voluntary or involuntary dissolution, liquidation and winding up of our affairs, prior to any distributions to holders of any class or series of our units that rank junior to the Series Q-1 and Q-2 preferred units (including the Class A-2 common units held by MergerCo), the Series Q-1 preferred unitholder will be entitled to receive a liquidating distribution equal to the amount it would receive if it held 11.58 Series O preferred units for each Series Q-1 unit and the Series Q-2 preferred unitholder will be entitled to receive a liquidating distribution equal to the amount it would receive if it held 4.96 Series O preferred units for each Series Q-2 unit.

        Before operating trust merger.    The Series N-1 and N-2 preferred unitholders are not entitled to any preference over any other class or series of our units in payment of distributions or upon our dissolution, liquidation, or winding. The Series N-1 and N-2 preferred units rank on par with the

133


Class A-1 and A-2 common units and the Series M preferred unit with respect to distributions and upon dissolution, liquidation, or winding up.

        After operating trust merger.    The Series Q-1 and Q-2 preferred units will rank on par with the Series I, O, and P preferred units and senior to the Class A-2 common units with respect to distributions and upon dissolution, liquidation, or winding up.

        Before operating trust merger.    From and after July 28, 2015, we have the right to redeem, in whole or in part, any Series N-1 or N-2 referred units that have not previously been converted as described below, upon not less than 10 nor more than 60 days' written notice, for cash at a redemption price of $416.67 per Series N-1 preferred unit and $178.57 per Series N-2 preferred unit.

        After operating trust merger.    From and after July 28, 2015, we have the right to redeem, in whole or in part, any Series Q-1 or Q-2 preferred units that have not previously been converted as described below, upon not less than 10 nor more than 60 days' written notice, for cash at a redemption price of $416.67 per Series Q-1 preferred unit and $178.57 per Series Q-2 preferred unit.

        Before operating trust merger.    When all or any portion of our Toluca Hills project becomes fully entitled (as defined in our declaration of trust) (each such event being referred to as an "entitlement event"), we will provide the holders of the Series N-1 and N-2 preferred units with written notice that an entitlement event has occurred and specifying the number of apartment units which have become fully entitled in connection with such entitlement event (each such apartment unit being referred to as an "approved apartment unit"). Upon each such entitlement event, a corresponding number of the Series N-1 and/or N-2 preferred units shall become convertible as described below.

        Upon each entitlement event that occurs when there are Series N-1 preferred units outstanding, the holder of the Series N-1 preferred units may convert a number of Series N-1 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event and (ii) the number of Series N-1 preferred units outstanding. Upon conversion, each Series N-1 preferred unit shall be converted into a number of Class A-1 common units equal to quotient of (x) $70,000 divided by (y) an amount equal to the average of the high and low trading prices for common shares of the company for the 30 trading day period ending five trading days before such entitlement event (such amount being referred to as the "entitlement value" with respect to such entitlement event).

        Upon each entitlement event that occurs at such time as the number of Series N-1 preferred units outstanding is less than the number of approved apartment units that become fully entitled as part of such entitlement event, the holder of the Series N-2 preferred units may convert a number of Series N-2 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event in excess of the number of Series N-1 preferred units outstanding and (ii) the number of Series N-2 preferred units outstanding. Upon conversion, each Series N-2 preferred unit shall be converted into a number of Class A-1 common units equal to quotient of (x) $30,000 divided by (y) the entitlement value with respect to such entitlement event.

        Upon each entitlement event that occurs at such time as there are no Series N-1 preferred units outstanding and there are Series N-2 preferred units outstanding, the holder of the Series N-2 preferred units may convert a number of Series N-2 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event and (ii) the number of Series N-2 preferred units outstanding. Upon conversion, each Series N-2

134



preferred unit shall be converted into a number of Class A-1 common units equal to quotient of (x) $30,000 divided (y) the entitlement value with respect to such entitlement event.

        After the operating trust merger.    Upon the occurrence of an entitlement event, we will provide the holders of the Series Q-1 and Q-2 preferred units with written notice that an entitlement event has occurred and specifying the approved apartment units which have become fully entitled in connection with such entitlement event. Upon each such entitlement event, a corresponding number of the Series Q-1 and/or Q-2 preferred units shall become convertible as described below.

        Upon each entitlement event that occurs when there are Series Q-1 preferred units outstanding, the holder of the Series Q-1 preferred units may convert a number of Series Q-1 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event and (ii) the number of Series Q-1 preferred units outstanding. Upon conversion, each Series Q-1 preferred unit shall be converted into a number of Series O preferred units equal to the quotient of (x) $70,000 divided by (y) $60.75.

        Upon each entitlement event that occurs at such time as the number of Series Q-1 preferred units outstanding is less than the number of approved apartment units that become fully entitled as part of such entitlement event, the holder of the Series Q-2 preferred units may convert a number of Series Q-2 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event in excess of the number of Series Q-1 preferred units outstanding and (ii) the number of Series Q-2 preferred units outstanding. Upon conversion, each Series Q-2 preferred unit shall be converted into a number of Series O preferred units equal to quotient of (x) $30,000 divided by (y) $60.75.

        Upon each entitlement event that occurs at such time as there are no Series Q-1 preferred units outstanding and there are Series Q-2 preferred units outstanding, the holder of the Series Q-2 preferred units may convert a number of Series Q-2 preferred units equal to the lesser of (i) the number of approved apartment units having become fully entitled in connection with such entitlement event and (ii) the number of Series Q-2 preferred units outstanding. Upon conversion, each Series Q-2 preferred unit shall be converted into a number of Series O preferred units equal to quotient of (x) $30,000 divided by (y) $60.75.

        No fractional Series O preferred units will be issued upon conversion of any Series Q-1 or Series Q-2 preferred units. Instead, an amount in cash will be paid in lieu of such fractional unit based on the value applicable to such conversion.

        Before operating trust merger.    The holders of the Series N-1 and N-2 preferred units do not have any voting rights or right to consent to any matter requiring the consent or approval of our unitholders, except as required by law and other than, as provided in the declaration of trust, certain approval rights regarding amendments to the terms of the Series N-1 and N-2 preferred units that are materially adverse to the rights or preferences of the Series N-1 and N-2 preferred units. See "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Amendment of Declaration of Trust" beginning on page 121.

        After the operating trust merger.    The holders of the Series Q-1 and Q-2 preferred units do not have any voting rights or right to consent to any matter requiring the consent or approval of our unitholders, except as required by law and except that the approval of each holder of a Series Q-1 or Q-2 preferred unit will be required for any amendment of the provisions of our new declaration of trust that require the approval of all adversely affected unitholders, as described above under "Comparison of Rights of Class A-1 Common Unitholders and Series O Preferred Unitholders—Amendment of Declaration of Trust—After Operating Trust Merger," to the extent any such amendment is applicable to the holders of the Series Q-1 or Q-2 preferred units and such holder is adversely affected.

135



MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

        The following is a summary of certain material federal income tax consequences of the operating trust merger to holders of Class A-1 common units who are "U.S. persons" as defined below and who hold their units as a capital asset.

        As used in this prospectus/information statement, for federal income tax purposes a "U.S. person" is:

        This summary is based on the Code, Treasury Regulations and judicial and administrative determinations, as each is in effect as of the date of this prospectus/information statement. You should be aware that the applicable laws, regulations, judicial decisions, and administrative interpretations are subject to change at any time and any such changes could have retroactive effect. Furthermore, all are subject to differing interpretation. No advance ruling has been sought or obtained from the Internal Revenue Service regarding the federal income tax consequences of the operating trust merger and the election. The statements in this prospectus/information statement are not binding on the Internal Revenue Service or a court. As a result, there can be no assurance that the tax considerations described herein will not be challenged by the Internal Revenue Service or sustained by a court if so challenged.

        The rules governing the taxation of partners and partnerships are extraordinarily complex, and the following discussion represents only a general summary of certain of those rules (and only at the federal level and as such rules apply to U.S. persons). This summary does not address aspects of income taxation other than federal income taxation. It also does not address all aspects of federal income taxation that may apply to holders of Class A-1 common units who are subject to special rules under the Code, including, without limitation, unitholders other than U.S. persons, persons who hold their units through entities that are partnerships or trusts for federal income tax purposes or other pass-through entities, tax-exempt organizations, financial institutions, broker-dealers, insurance companies, persons having a "functional currency" other than the U.S. dollar, persons who received units as compensation or who hold their units as part of a straddle, wash sale, hedging, conversion or other integrated or risk reduction transaction, corporations subject to Code Section 7874, and certain U.S. expatriates. In addition, this summary does not address the state, local or foreign tax consequences of the operating trust merger and the election.

        This discussion is not intended to be, and should not be construed as, tax advice to any unitholder. The tax consequences to you of the transactions and your rights with respect thereto are based upon your particular circumstances, which will differ from those of other unitholders. Accordingly, some or all of the following discussion may not apply to your particular situation. In view of the foregoing, and given that the federal income tax consequences of the operating trust merger are uncertain in some material respects, you are strongly urged to consult and rely on your own tax adviser with respect to the federal, state, local and foreign tax consequences of the operating trust merger and the election

136



based upon your particular circumstances, including the tax consequences to you of receiving cash and/or receiving Series O preferred units in the operating trust merger.

        For purposes of this summary, the operating trust is considered to be a partnership for federal income tax purposes, and it also is considered to be a continuation of Charles E. Smith Residential Realty L.P., which merged with and into the operating trust in October 2001. Therefore, for holders of Class A-1 common units issued at the time of the Charles E. Smith Residential Realty L.P. merger, references to contributions of property to the operating trust in exchange for Class A-1 common units and related considerations (including the basis of a unitholder in his or her Class A-1 common units and his or her allocable share of the liabilities of the operating trust) are to their contributions of property to Charles E. Smith Residential Realty L.P. in exchange for the operating partnership units that were converted into Class A-1 common units in that merger.


The Election

        Pursuant to the merger agreement, at the operating trust merger effective time, each Class A-1 common unit of the operating trust issued and outstanding immediately prior to the operating trust merger effective time (other than units held by unitholders who have properly exercised and perfected their appraisal rights, if any, under Maryland law) will automatically be converted into the right to receive one Series O preferred unit. Alternatively, as a Class A-1 common unitholder, you have the right to elect to receive for your Class A-1 common units:

        Based upon the currently anticipated financing arrangements to be undertaken in connection with the election, we expect that, and intend to report that, the receipt by you of the cash consideration in exchange for your Class A-1 common units will be treated for federal income tax purposes as a sale of those Class A-1 common units to MergerCo, rather than as a redemption of those units by the operating trust. This characterization, as discussed below, could have a material impact on the tax liability that you incur as a result of the receipt of cash consideration in the operating trust merger.


Treatment of Class A-1 Unitholders Receiving Cash

        If you receive cash in exchange for all of your Class A-1 common units, or if you receive cash in exchange for a portion of your Class A-1 common units, you generally will recognize gain in an amount equal to the excess of (1) your "amount realized" for federal income tax purposes, which equals the amount of cash consideration received (including any amounts of cash withheld), plus your share of our pre-merger liabilities attributable to the units exchanged, over (2) your aggregate adjusted tax basis in those Class A-1 common units exchanged for cash (including the basis attributable to your share of our pre-merger liabilities attributable to the units exchanged). If you receive cash in exchange for all or a portion of your Class A-1 common units, you would recognize a loss to the extent that the amount of your basis described in clause (2) above exceeds your amount realized described in clause (1) above. Because your "amount realized" includes the amount of our liabilities allocated to you immediately prior to the operating trust merger, it is possible that the amount of gain you recognize upon the receipt of cash, or even your resulting tax liability, could exceed the amount of cash you actually receive, perhaps by a significant amount.

        You will be allocated your proportionate share of the operating trust's taxable income and gain for the period ending with the date of the operating trust merger (including income and gain attributable

137



to asset sales undertaken by the operating trust at the request of the buyer parties in contemplation of the mergers, if any), even if you elect to exchange all of your Class A-1 common units for cash. These allocations will be made in accordance with the terms of the existing declaration of trust and taking into account any required special allocations, including Code Section 704(c) allocations with respect to built-in gain on contributed property. You will have to include in your taxable income your share of such income even though you will not receive any additional cash distributions from the operating trust attributable to such income. The income of the operating trust for such period could include ordinary income, which would be subject to federal income tax at a maximum rate of 35%, rather than the maximum 15% rate generally applicable to long-term capital gains of non-corporate taxpayers, and could include other income that is taxable at a rate that exceeds the long-term capital gains rate. As discussed below in the section captioned "—Basis in Class A-1 common units" on page 139, any income allocated to Class A-1 common units with respect to the period prior to the operating trust merger or the date you exchange your Class A-1 common units for cash, as applicable, will increase your adjusted tax basis in your units for purposes of calculating the gain or loss that you will recognize on the exchange of such units for cash in the operating trust merger.

        Except as described in the following paragraphs, any gain or loss that you recognize upon the exchange of your Class A-1 common units for cash, computed as described above, generally will be capital gain or loss and will be treated as long-term capital gain or loss to the extent that you have a holding period in your Class A-1 common units of more than one year. Pursuant to Treasury Regulations under Code Section 1223, if you acquired any Class A-1 common units or contributed any cash or property to the operating trust within a year of the exchange, all or a portion of your Class A-1 common units may have a holding period of one year or less, and all or a portion of any gain or loss recognized upon the exchange of your Class A-1 common units may be short-term capital gain or loss. You should consult your tax adviser regarding the determination of your holding period in your Class A-1 common units.

        Notwithstanding the general rule that any gain or loss you recognize upon an exchange for cash will be capital gain or loss, it is possible that you could recognize ordinary income or loss under the special rules of Code Section 751. Under Code Section 751, you generally will recognize ordinary income (or loss) on an exchange of your Class A-1 common units to the extent that the exchange reduces your interest in the operating trust's inventory and "unrealized receivables" (referred to as "hot assets"). For this purpose, "unrealized receivables" are defined generally as rights to receive payment for goods and services to the extent not already included in income, as well as any amounts of ordinary income the partnership would recognize if it sold its properties for fair market value (including, for example, certain depreciation recapture on the sale of property that has a value in excess of its tax basis). "Inventory" for this purpose may include any of the operating trust's properties that have not been held for more than one year. As of the date of this prospectus/information statement, it is unclear whether Code Section 751 will have a material impact on the tax consequences of a holder of Class A-1 common units who elects to receive the cash consideration in exchange for his or her Class A-1 common units. To the extent that the trustee determines that the operating trust holds hot assets with material amounts of appreciation at the time you exchange your Class A-1 common units for cash, the trustee of the operating trust will provide you with the information needed for you to calculate the consequences under Code Section 751, to the extent reasonably practicable. It is possible, however, that the Internal Revenue Service could disagree with the trustee's assessment that certain assets are not hot assets. The rules under Code Section 751 are very complex and you should consult with your own tax adviser regarding the impact of these rules on your personal tax situation.

        In addition to the possibility of recognizing ordinary income under Code Section 751, if you are an individual or a taxable trust or estate, a portion of any long-term gain you recognize on the exchange

138



of your Class A-1 common units for cash likely will be characterized as unrecaptured Section 1250 gain and subject to an increased capital gain tax rate of 25%. Specifically, the Treasury Department has promulgated regulations that provide that a partner selling a partnership interest with a long-term holding period generally recognizes "Section 1250 capital gain" (from which the partner calculates his or her unrecaptured Section 1250 gain) equal to the gain that would be allocated to such partner (to the extent attributable to the portion of the partnership interest transferred that was held for more than one year) if the partnership sold all of its Section 1250 property for fair market value immediately before the partner transferred its interest (the "Section 1250 look through rule"). The assets of the operating trust currently have significant unrecaptured Section 1250 gain associated with them, so that you should expect to recognize Section 1250 capital gain under the Section 1250 look-through rule if you elect to exchange your Class A-1 common units for cash. The amount of Section 1250 capital gain recognized by any particular Class A-1 common unitholder will depend upon a number of factors, including facts unique to that particular unitholder (such as when and the manner in which the unitholder acquired his or its Class A-1 common units). To the extent reasonably practicable, the trustee of the operating trust will provide you with the information needed for you to calculate your unrecaptured Section 1250 gain recognized in connection with your exchange of your Class A-1 common units for cash.

        The amount of your long-term capital gain (after the application of Code Section 751 as described above) that is not taxed at the increased rate for Section 1250 capital gain will be taxed at regular long-term capital gain rates.

        In general, your basis in your Class A-1 common units at the time of the operating trust merger will be determined under the rules described below. If you acquired your Class A-1 common units by contribution of property and/or money to the operating trust, you had an initial tax basis in your Class A-1 common units equal to the sum of:

        The initial basis of Class A-1 common units acquired by other means would have been determined under the general rules of the Code, including the partnership provisions. Other rules, including the "disguised sale rules", also may affect initial basis, and you are urged to consult your own tax adviser regarding the calculation of your initial basis in your Class A-1 common units.

        Your basis in your Class A-1 common units generally is increased by:

        Your basis in your Class A-1 common units is decreased, but not below zero, by:

139


        The operating trust generally does not have all of the information necessary to compute your adjusted tax basis in you Class A-1 common units, and thus you, together with your own tax adviser, will be responsible for computing that amount (and thus your resulting gain from the exchange of your Class A-1 common units for the cash consideration in the operating trust merger).

        Your share of the operating trust's liabilities has a significant impact on the tax consequences to you of the operating trust merger. This is true whether you elect to exchange any of your Class A-1 common units for cash, as discussed above, or whether you receive Series O preferred units in conversion of your Class A-1 common units in the operating trust merger, as discussed below. The following is a general summary of the rules for determining your share of the operating trust's liabilities. Because of the complexity of the rules under which partnership liabilities are allocated, you are strongly urged to consult with your tax adviser regarding the application of these rules to your particular circumstances.

        A partner's share of the liabilities of a partnership is determined under Code Section 752 and the Treasury Regulations thereunder. In general, each liability of a partnership is first allocated to the partner or partners who bear the economic risk of loss with respect to that liability (either directly or indirectly through an affiliate of the partner). Such a liability is referred to as a "recourse liability." Among other things, a partner could be considered to bear the economic risk of loss of an operating trust liability pursuant to a contractual obligation to a lender to the operating trust (such as pursuant to a guarantee) or to the operating trust itself, or if the partner (or an affiliate of the partner) is the lender to the operating trust with respect to that liability. In general, liabilities for which no partner bears the economic risk of loss, so-called "nonrecourse liabilities", are allocated among the partners in three tiers: first, among the partners in proportion to certain deductions or distributions that were financed by the liabilities; second, in proportion to the taxable gain that would be allocated to each partner under Code Section 704(c) (or under the principles of Code Section 704(c)) if the assets of the partnership subject to the nonrecourse liabilities were sold for an amount equal to the nonrecourse liabilities; and third, in proportion to the partners' interests in the profits of the partnership, or, alternatively, in accordance with the manner in which it is reasonably expected that the deductions attributable to those nonrecourse liabilities will be allocated. Prior to other third-tier allocations, an excess nonrecourse liability encumbering a property may be allocated to a partner up to the amount of built-in gain that would be allocated to such partner under Code Section 704(c) principles on a sale or other taxable disposition of the property, excluding any gain taken into account under the second tier.

        The amount, if any, by which a partner's share of a partnership's liabilities exceeds the partner's adjusted basis in its partnership interest is commonly referred to a "negative tax capital account"—that amount corresponds to the gain that a partner would recognize upon a reduction or elimination of its share of the liabilities of the partnership, above and beyond the amount of any consideration that the partner actually may receive in connection therewith. If (1) you acquired your Class A-1 common units in exchange for a contribution of property, the operating trust assumed liabilities in connection with that contribution, and your share of those liabilities exceeded your adjusted basis in the property that you contributed to the operating trust, (2) you have received aggregate distributions from the operating trust in excess of the aggregate income and gain allocated to you by the operating trust while you have held your Class A-1 common units, or (3) you otherwise believe you may have an allocable share of liabilities of the operating trust that exceeds your tax basis in your Class A-1 common units, you may

140



have a negative tax capital account with respect to your Class A-1 common units. If you have a negative tax capital account with respect to your Class A-1 common units that you exchange for cash consideration in the operating trust merger, you will recognize gain on the receipt of the cash consideration equal to the sum of the amount of the cash consideration that you actually receive plus the amount of your negative tax capital account with respect to those Class A-1 common units. If you have a negative tax capital account, you will have taxable gain, and even could have a tax liability, in excess of the amount of cash you receive.

        As described below, you could also experience a reduction in your share of the operating trust's liabilities if you receive only Series O preferred units in the operating trust merger. In that event, if you have a negative tax capital account with respect to your Class A-1 common units, you will recognize gain in connection with the operating trust merger equal to the lesser of the amount of that reduction or your negative tax capital account, notwithstanding that you do not receive any cash consideration in connection with the operating trust merger.

        Code Section 465(e) requires individuals and closely held corporations to recapture losses previously allowed with respect to their interests in a partnership in the event their amount "at risk" with respect to that partnership becomes less than zero. The consequence of recapture is that a taxpayer must recognize income equal to the negative at-risk amount. Your at-risk amount, or "at-risk basis", is generally equal to your basis in your Class A-1 common units, adjusted to exclude certain non-qualified partnership liabilities that otherwise would be included in basis. In addition, although guidance is sparse, your at-risk basis likely will be increased by the amount of any gain recognized with respect to your Class A-1 common units (e.g., as a result of exchanging Class A-1 common units for cash). Assuming such gain increases your at-risk basis, you should not recognize recapture income under Code Section 465(e) solely as a result of electing to exchange your Class A-1 common units for the cash consideration. If you may be subject to these "at risk" rules, you should consult your tax adviser concerning your share of the operating trust's qualifying indebtedness and the application of these rules to your particular circumstances.

        The basis rules under Code Section 704(d) or the "at-risk" rules under Code Section 465 may have prevented you from deducting all or a portion of your distributive share of any of losses from the operating trust. These limitations are applied separately and in sequence. Losses previously suspended under Code Section 704(d) will not be available to offset any gain that you recognize if you elect to receive the cash consideration in exchange for your Class A-1 common units. Losses previously allowed under Code Section 704(d) but suspended under Code Section 465, by contrast, may be used to offset gain that you recognize to the extent that the gain gives you a positive at-risk basis in your Class A-1 common units, as discussed above.

        Any gain that you recognize with respect to your Class A-1 common units will generally be treated as passive activity income (except to the extent attributable to any operating trust activity that is not a passive activity with respect to you), and thus may be offset, as applicable, by any passive activity losses that you incur in the taxable year of the exchange and by suspended passive activity losses from prior years (i.e., losses previously allowed under Code Sections 704(d) and 465, but disallowed under Code Section 469). If the operating trust were considered a "publicly traded partnership," you would not be able to utilize passive activity losses attributable to any investment or activity other than your ownership of an interest in the operating trust. The operating trust has never taken the position that it is a "publicly traded partnership," but there can be no assurance that the IRS could not successfully contend that the operating partnership is a publicly traded partnership. The operating trust does not

141



qualify for any of the safe harbors available under the applicable Treasury Regulations that would permit it to avoid with certainty classification as a publicly traded partnership.

        A non-corporate holder of Class A-1 common units may be subject to information reporting and backup withholding on any cash payments he or she receives in connection with the operating trust merger. Such a unitholder will not be subject to backup withholding, however, if he or she:

        Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against a unitholder's federal income tax liability, provided such unitholder furnishes the required information to the Internal Revenue Service.


Treatment of Unitholders that Receive Series O Preferred Units

        The operating trust intends that you should not recognize any gain or loss if you receive only Series O preferred units in the operating trust in exchange for your Class A-1 common units. The proper tax characterization, however, of preferred equity interests in a partnership, such as the Series O preferred units, for federal income tax purposes is complicated and in a number of respects uncertain, and there is a risk that the IRS could assert that holders of Series O preferred units should be treated as creditors of the operating trust for federal income tax purposes. If you were treated as a creditor of the operating trust, the operating trust, MergerCo, and Parent would take the position that you recognize no immediate gain or loss as a result of the receipt of the Series O preferred units but that gain or loss would be recognized over time under rules applicable to payments made in liquidation of the interest of a retiring partner (generally, as and when distributions are made or deemed made to the extent that they exceed the adjusted basis of the retiring partner in his or her Series O preferred units). There can be no assurance, however, that the IRS would respect such characterization or would not seek to treat you as recognizing gain at the time of the operating trust merger.

        Neither the operating trust nor MergerCo intend to treat you as a creditor of the operating trust for federal income tax purposes. None of the operating trust, the company, Parent or MergerCo, or anyone else, however, is making any commitment to you that your receipt of Series O preferred units will be effective to permit you to defer all or any part of the taxable gain that you otherwise would have recognized had you elected to receive cash for your Class A-1 common units. If, and to the extent that, you receive Series O preferred units in the operating trust merger and nevertheless are required to recognize gain, the considerations set forth above under "Treatment of Class A-1 Unitholders Receiving Cash" on page 137 would apply, and thus you should read that section carefully even if you plan to receive Series O preferred units in the operating trust merger. If, and to the extent that you receive Series O preferred units in the operating trust merger but are required to recognize gain because you are treated as a creditor of the operating trust, rather than as a partner in the operating trust for federal income tax purposes, you may be able to defer the tax liability attributable to a portion of the gain that you are required to recognize as a result of the operating trust merger, but you may, depending upon your personal circumstances, owe the IRS a non-deductible interest payment on that deferred tax liability.

        The remainder of this discussion assumes that unitholders that receive Series O preferred units, rather than the cash consideration, in exchange their Class A-1 common units will continue to be

142



treated as partners in the operating trust for federal income tax purposes and not as creditors of the operating partnership.

        Even assuming that the Series O preferred units are respected as equity interests in the operating trust for federal income tax purposes, you could recognize gain if, as a result of our post-merger financing and/or dispositions of assets, you experience a reduction in your share of our liabilities and the amount of that reduction exceeds your adjusted tax basis in your Class A-1 common units immediately prior to the operating trust merger. In this regard, if you have an existing guarantee of indebtedness of the operating trust, such obligation will continue in effect after the operating trust merger unless the debt to which your guarantee applies is repaid or refinanced, in which case you will be entitled only to the rights you have under any applicable tax protection agreement. As a general matter, if you elect to receive Series O preferred units in connection with the operating trust merger, the continuation of your existing guarantee is intended to allow you to avoid the potentially adverse tax consequences that might result from a reduction of your share of liabilities of the operating trust (such as the recognition of currently deferred gain attributable to your negative capital account and at-risk recapture). We cannot offer you any assurances, however, as to whether these arrangements have in the past or will in the future have the intended tax effect. Moreover, unless you are the beneficiary of a tax protection agreement that specifically requires us to maintain such guarantees in place, except as otherwise provided in the new declaration of trust, we have no obligations to you in connection with our decisions as to the structuring of our financing arrangements following the operating trust merger, including whether to maintain the debt subject to the guarantees in place, to offer you opportunities to enter into new guarantees, or to avoid taking steps that might make it more likely that a lender would require you to pay on your guarantee.

        If you receive Series O preferred units, you also may be required to recognize income under other circumstances. This would be the case if, in connection with the operating trust merger, your interest in "hot assets" (as discussed in the section captioned "—Character of Gain Recognized" on page 138) decreases, and at the same time, your share of partnership liabilities (as discussed above under the section captioned "—Share of Liabilities" on page 140) decreases. Your share of hot assets and partnership liabilities could both decrease, for example, as a result of an issuance of additional partnership interests in the operating trust to the trustee or another person. If this were the case, you would be required to recognize ordinary income under the "hot assets" rules of Code Section 751.

        Furthermore, even if you do not experience a reduction in your share of our liabilities for purposes of determining your basis in your Series O preferred units, you may, as a result of refinancing of certain of our mortgage debt, experience a reduction in your share of our qualified at-risk liabilities. If any such reduction in your share of qualified at-risk liabilities exceeded your at-risk basis, you would recognize at-risk recapture as described in the section captioned "—Possible At-Risk Recapture" on page 141.

        Holders of Class A-1 common units that are converted into Series O preferred units in the operating trust merger will be allocated their distributive share of the operating trust's taxable income for the period ending with the date of the operating trust merger (including income and gain attributable to asset sales undertaken by the operating trust at the request of the buyer parties in contemplation of the mergers). Even though you will not receive any additional cash distributions from the operating trust attributable to such income, you will have to report such income notwithstanding the conversion of your Class A-1 common units into Series O preferred units pursuant to the operating trust merger. The amounts of such income and gain could be significant.

143


        The operating trust is, and after the operating trust merger, the operating trust will continue to be, organized as a Maryland real estate investment trust that is treated as a partnership for federal income tax purposes. An entity treated as a partnership generally is not subject to federal income tax at the entity level.

        As a holder of Series O preferred units, you will report on your federal income tax return your allocable share of the operating trust's income, gains, losses, deductions and credits. As is currently the case, such items must be included on your federal income tax return without regard to whether the operating trust makes a distribution of cash to you. Accordingly, you may be required to pay taxes on your income resulting from your investment in the operating trust for any taxable year without having any cash distributions from the operating trust with which to pay such taxes, and in such event, you will have to utilize other means with which to satisfy such tax liabilities. Distributions of money by the operating trust to you generally will not be taxable unless the amount of the distribution exceeds your adjusted basis in your Series O preferred units.

        As a result of the transactions contemplated herein, the amount, timing and character of your allocable share of the operating trust's income, gains, losses, deductions and credits may be different from, and potentially less favorable than, the manner in which the operating trust has allocated such items to you in the past. For example, as a result of the company merger (which will be treated as a taxable sale by the company of all of its assets, including its interest in the operating trust, to MergerCo), the operating trust will be deemed "terminated" for federal income tax purposes. As a result, the operating trust will be treated as a new partnership for federal income tax purposes. Our taxable year will end, and the operating trust will have to depreciate the remaining tax basis in its assets over a new depreciation period. Generally, this means that the operating trust's tax depreciation deductions will be lower and the operating trust's taxable income will be higher than would have been the case otherwise because we will have to depreciate the remaining basis of our depreciable assets over a longer period than would apply in the absence of such tax termination. Other circumstances, including tax elections made by the trustee, also could adversely impact the amount of taxable income and deductions allocable to you.

        As a holder of Series O preferred units, you generally will be allocated items of the operating trust's income and gain up to the amount of preferred return that has accrued with respect to your Series O preferred units, whether or not that preferred return is actually paid, plus any losses previously allocated to you. Moreover, you also may be allocated additional taxable income or gain as a result of Section 704(c) of the Code or other applicable tax rules. In this regard, you will be allocated, under Section 704(c) of the Code and related principles, your proportionate share of the operating trust's gain attributable to assets sold after the date of the operating trust merger, to the extent that gain would have been allocated to you if the assets of the operating trust were sold for fair market value at the time of the operating trust merger (your allocable share of the gain that would have been recognized if the assets of the operating trust were sold at the time of the mergers for their fair market value is treated as Section 704(c) gain and will be allocated to you if and when those assets are actually sold so long as you hold Series O preferred units at the time of such a sale). These income and gain allocations will include the income and gain attributable to asset sales undertaken by the operating trust at the direction of the buyer parties in connection with the mergers, if any. The amount of income and gain that you will be required to recognize as a result of any such asset sales will depend upon your particular circumstances, including when and how you obtained your Class A-1 common units and whether some of the properties that are to be sold are properties in which you contributed an interest (or were treated as contributing an interest) to the operating trust. The amount of income and gain that you could be required to recognize as a Series O preferred unitholder as a result of any such asset

144



sales, however, could be significant. You will have to report such income and gain for tax purposes even though you will not receive any additional cash distributions from the operating trust attributable to such income. To the extent, however, that gain is recognized with respect to properties that are covered by existing tax protection agreements with certain Class A-1 common unitholders, you will be entitled to indemnification as and to the extent provided in such agreements.

        If your Class A-1 common units are converted into Series O preferred units in the operating trust merger, your initial basis in your Series O preferred units immediately after the operating trust merger generally will equal your basis in your Class A-1 common units immediately prior to the operating trust merger, as adjusted to take into account the effects of the operating trust merger.

        As a general matter, if you receive Series O preferred units in connection with the operating trust merger and you have an existing guarantee, such obligation will continue in effect after the operating trust merger unless the debt to which your guarantee applies is repaid or refinanced, in which case you will be entitled only to the rights, if any, that you have under an existing tax protection agreement with the operating trust. As a general matter, the continuation of your existing guarantee or entering into any substitute guarantee is intended to allow you to avoid the potentially adverse tax consequences that might result from a reduction of your share of liabilities of the operating trust (such as the recognition of currently deferred gain attributable to your negative capital account and at-risk recapture). There cannot be any assurances, however, as to whether these arrangements will have the intended tax effect. Holders receiving Series O preferred units should consult their legal and tax advisers regarding the terms of any applicable tax protection agreements with respect to which they are entitled to benefits.

        As a Series O preferred unitholder, a distribution of money by the operating trust to you (including for this purpose, deemed cash distributions attributable to decreases in your share of partnership liabilities) generally will not be taxable to you for federal income tax purposes to the extent the distribution does not exceed your adjusted basis in your Series O preferred units immediately before the distribution. Distributions of money in excess of such basis generally will be considered to be gain in the amount of such excess, a portion of which may be taxed as ordinary income. As noted previously, any reduction in your share of partnership liabilities—whether through payment, refinancing with recourse liabilities, refinancing with nonrecourse liabilities secured by other assets, expiration (or partial termination) of any debt guarantee you may have, or otherwise, including in connection with the transactions described in this prospectus/information statement, will be treated as a distribution of money to you.

        Furthermore, if you acquired your Class A-1 common units in exchange for a contribution of property other than cash within two years of a reduction in your share of partnership liabilities which, as described above, is treated as distribution of money to you, you should be aware that the regulations governing "disguised sales" of property to a partnership generally provide that if within a two-year period a partner transfers property to a partnership and the partnership transfers money to the partner (other than certain operating cash flow distributions and certain other excepted distributions, but including certain reductions in a partner's share of partnership liabilities), the transfers are treated as a taxable disguised sale of the property to the partnership unless the facts and circumstances clearly establish that the transfers do not constitute a sale. You should consult your tax adviser regarding the effect of a reduction in your share of partnership liabilities in your own particular circumstances, including applicable filing and disclosure requirements.

        In addition to any gain that might be recognized by you as a result of the conversion of your Class A-1 common units into Series O preferred units of the operating trust and/or sales of properties undertaken by the operating trust in connection with the mergers, a variety of future events and

145


transactions could cause you to recognize part or all of any taxable gain that has been deferred with respect to your Class A-1 common units (such as gain deferred upon your original contribution of assets to the operating trust in exchange for units).

        Such future events or transactions might include, but are not limited to, (1) the exercise by the operating trust of its right, commencing on the fifth anniversary of the operating trust merger, to redeem all of the Series O preferred units then outstanding at a cash redemption price per Series O preferred unit equal to $60.75 plus any accrued and unpaid preferred return and the applicable tax protection amount for each holder; (2) the sale or other taxable disposition by the operating trust of one or more of the individual properties contributed by you (or certain substitute properties) and the sale by the operating trust of assets held at the time of the operating trust merger under which you will receive an allocation of income for tax purposes under Section 704(c) of the Code or similar principles, (3) the reduction in the amount of nonrecourse liabilities secured by individual properties contributed by you or otherwise, (4) the issuance by the operating trust of additional partnership interests, (5) an increase in the tax basis of properties contributed by you resulting from capital expenditures, (6) the special allocations of tax and/or book items related to nonrecourse debt, (7) the expiration of your existing guarantee (if you are a party to one), and (8) the elimination over time, through required or elective special allocations of tax items in a manner different than the manner in which corresponding book items are allocated, of the disparity between the tax basis of the individual properties contributed by you and the book values of such properties. Each of these items (1) through (8) are examples of events that could result in the allocation of taxable gain to you or could have the effect of reducing the amount of the operating trust's liabilities allocable to you and therefore could result in deemed cash distributions or otherwise cause adverse tax consequences to you. Subsequent events also could trigger at-risk recapture, if applicable to you, under the rules discussed in the section captioned "—Possible At-Risk Recapture" on page 141.

        Except as specifically provided in the terms of the Series O preferred units or an existing tax protection agreement, the trustee and the operating trust will not be required to take into account the tax consequences to the holders of the Series O preferred units, including you, in deciding whether to cause the operating trust to undertake specific transactions or make tax elections that could cause you to recognize gain.

        Consequently, any deferred gain with respect to your retained partnership interest in the form of Series O preferred units could be triggered at any time, and neither the trustee nor the operating trust is making any commitment to you that you will continue to enjoy the benefit of deferring any such gain. In this regard, as noted previously, the operating trust intends to sell a significant portion of its assets in connection with the mergers and the Series O unitholders will be allocated their distributive share of income and gain attributable to these asset sales under the principles of Section 704(c) of the Code, but will not receive any additional cash distributions attributable to such gain.

        As discussed elsewhere in this prospectus/information statement, including under the section titled "Description of the Series O Preferred Units" on page 108, holders of Series O preferred units will have the right, commencing on the fifth anniversary of the operating trust merger (or, in certain limited circumstances discussed elsewhere in this prospectus/information statement, prior to such date), to request that the operating trust redeem some or all of their Series O preferred units at a redemption price of $60.75 per unit plus any accrued and unpaid preferred return thereon.

        In addition, commencing on the fifth anniversary of the operating trust merger, the operating trust may redeem all (but not less than all) of the outstanding Series O preferred units at a redemption price equal to the stated value plus accumulated but unpaid distributions. As described above under the section titled "Description of the Series O Preferred Units" on page 108, if the operating trust redeems, at its option, the Series O preferred units at any time during the period which the operating

146



trust is prohibited from selling a property under an applicable tax protection agreement, such redemption shall be deemed to be a taxable disposition of all properties subject to such tax protection agreement. In such a case, the operating trust is required to make, in addition to the payment of those amounts otherwise due the redeemed holder in connection with such redemption, all payments required to be made under such tax protection agreements as a result of such deemed disposition of properties. Holders of Series O preferred units should consult their legal and tax advisers regarding the terms of any applicable tax protection agreement with the operating trust with respect to which they are entitled to benefits.

        The tax treatment to you of a redemption of your Series O preferred units will depend upon whether (1) the redemption is treated for tax purposes as a sale of your Series O preferred units to the operating trust, or as a distribution of cash by the operating trust to you with respect to your Series O preferred units, and (2) if the redemption is treated for tax purposes as a distribution of cash by the operating trust to you with respect to your Series O preferred units (rather than as a sale of your Series O preferred units to the trustee), whether all or only a portion of your Series O preferred units are redeemed. Under the terms of the certificate of designation, the trustee has the right (unless otherwise prohibited in any applicable tax protection agreement) to cause any redemption to be structured as a sale of Series O preferred units to the trustee. Because there are certain tax advantages for the trustee and its affiliates from sale treatment, as compared to distribution treatment, you should assume that, unless you are the beneficiary of a tax protection agreement that would preclude that approach, any redemption of your Series O preferred units is likely to be structured in a manner such that it will be treated as a sale of those units to the trustee, rather than as a distribution of cash by the operating trust to you with respect to your Series O preferred units.

        If you sell some or all of your Series O preferred units, whether to the trustee in connection with a redemption of those units or otherwise, you generally will recognize gain in an amount equal to the excess of (1) your "amount realized" for federal income tax purposes, which equals the amount of cash or other consideration actually received for those Series O preferred units that are sold, plus your share of our liabilities attributable to the Series O preferred units sold, over (2) your aggregate adjusted tax basis in those Series O preferred units sold (including basis attributable to your share of our liabilities attributable to the units sold). You would recognize a loss to the extent that the amount of your basis described in clause (2) above exceeds your amount realized described in clause (1) above. Because your "amount realized" includes the amount of our liabilities allocated to you with respect to the Series O preferred units that are sold, it is possible that the amount of gain you recognize upon a sale of your Series O preferred units, whether pursuant to the redemption provisions or otherwise, could exceed the amount of cash you actually receive, perhaps by a significant amount.

        If some or all of your Series O preferred units are redeemed pursuant to either of these redemption rights, and if such redemption is treated as a distribution of cash by the operating trust in redemption of those units for federal income tax purposes (rather than as a sale of the Series O preferred units to the trustee), you generally will recognize gain equal to the excess of (1) the amount of cash you receive in such redemption plus the amount of operating trust liabilities allocable at the time of the redemption to the Series O preferred units you redeem (which generally would be the reduction in your share of our liabilities resulting from the redemption), such sum being your "amount realized" on the redemption, over (2) your aggregate basis in all of your Series O preferred units at the time of the redemption (as discussed in the section captioned "—Basis in Class A-1 common units" on page 139) (including basis attributable to your pre-redemption share of the operating trust liabilities). If the operating trust redeems all of your Series O preferred units, you generally would recognize a loss to the extent that the amount of your basis described in clause (2) of the preceding sentence exceeds the amount realized described in clause (1) of the preceding sentence. If the operating trust redeems less than all of your Series O preferred units and the redemption is treated as a distribution, rather than a sale, you generally are not permitted to recognize any loss. Because the amount paid to redeem your Series O preferred units includes any reduction in your share of the operating trust liabilities, it is

147



possible that the amount of gain recognized on such redemption, or even the tax liability resulting from such redemption, could exceed the amount of cash you actually receive, perhaps by a significant amount.

        Except as described in the next paragraph and in the section captioned "—Character of Gain Recognized" on page 138, any gain or loss that you recognize upon a redemption of your Series O preferred units, computed as described above, generally will be capital gain or loss and treated as long-term capital gain or loss, assuming you have a holding period in your Series O preferred units of more than one year, and subject to the rules set forth regarding Section 751 "hot assets" as discussed above under "—Character of Gain Recognized" on page 138.

        Under the Section 1250 look-through rule, you should expect to recognize unrecaptured Section 1250 gain to the extent of your share of the unrecaptured Section 1250 gain inherent in the assets of the operating trust at the time your Series O preferred units are redeemed pursuant to the redemption provisions (or at the time of a sale of your Series O preferred units to another party). The Section 1250 look-through rule would not apply, and you would not recognize unrecaptured Section 1250 gain, to the extent that a redemption of your Series O preferred units by the operating trust is treated for federal income tax purposes as a distribution by the operating trust to you in liquidation of part or all of your interest in the operating trust, rather than as a sale. As noted, however, the operating trust has the right (subject only to any limitations set forth in applicable tax protection agreements) to cause redemptions to be effected as a purchase of your Series O preferred units, and the trustee and its affiliates generally will realize certain benefits from that structure. Accordingly, unless you are the beneficiary of such a tax protection agreement, you should not assume that you will be able to avoid the increased rate of tax that would apply to your allocable share of the operating trust's unrecaptured Section 1250 gain.

        You should speak with your own tax adviser regarding the consequences to you in your particular circumstances of redemption of your Series O preferred units.

* * *

        Because the tax consequences to you of the operating trust merger will depend in significant part on your particular factual circumstances and are uncertain in some material respects, you should consult your own tax adviser as to the specific tax consequences to you resulting from the operating trust merger, the exchange of your Class A-1 common units for cash or the conversion of your Class A-1 common units into Series O preferred units and the tax consequences to you of holding Series O preferred units, including the application and effect of federal, state, local and foreign tax laws to you.

ARCHSTONE-SMITH OPERATING TRUST AFTER THE MERGERS

Business and Management

        We focus on apartment investment, management and operations. We own and operate a portfolio of high-rise and garden apartment communities concentrated in many of the most desirable neighborhoods in the Washington, D.C. metropolitan area, Southern California, the New York City metropolitan area, the San Francisco Bay Area, Boston and Seattle. As of March 31, 2007, we owned or had an ownership position in 344 communities, representing 86,014 units, including units under construction. The buyer parties have informed us, however, that they expect to cause the operating trust to distribute to the company a portfolio of assets valued at approximately $9.1 billion (based on the Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007) following the consummation of the operating trust merger. It is anticipated that all of our German and development assets will be included in the distributed assets. As a result, the buyer parties have informed us that it is not their current intention for the operating trust to engage in any development activities or own any foreign assets. In addition, the buyer parties may cause the operating trust to sell or distribute additional properties concurrently with or following the completion of the mergers. The buyer parties do not currently intend for us to acquire any additional properties, participate with third parties in property ownership or invest in securities of other REITs or securities of other entities engaged in real estate activities, in each case, following the consummation of the mergers, although the buyer parties may decide to do so at any time in the future. Other than as described above and elsewhere in this prospectus/information statement, it is the buyer parties' current intention for the operating trust to continue to own, operate and manage its assets consistent with past practice immediately after the mergers.

        Following the consummation of the mergers, MergerCo, as the surviving entity of the company merger, will be our sole trustee and we currently anticipate that our existing executive officers will remain executive officers following the consummation of the mergers. However, because MergerCo and we will be controlled by TS Fund VII and Lehman Brothers, they will indirectly have the power to make decisions on our behalf.


Employees

        We currently employ approximately 2,595 individuals, of whom approximately 1,958 are focused on the site-level operation of our garden communities and high-rise properties. Of the site-level associates, approximately 141 are subject to collective bargaining agreements with four unions in Illinois and New York. The balance are professionals who manage corporate and regional operations, including our investment program, property operations, financial activities and other support functions. We consider our relationship with our employees to be very good.


Competition

        There are numerous commercial developers, real estate companies and other owners of real estate that we compete with in seeking apartment communities for acquisition and disposition and residents for apartment communities. All of our apartment communities are located in developed areas that include other apartment communities. The number of competitive apartment communities in a particular area could have a material adverse effect on our ability to lease units and on the rents charged. In addition, single-family homes and other residential properties provide housing alternatives to residents and potential residents of our apartment communities.


Properties

        The buyer parties have informed us that they presently intend to cause the operating trust to distribute to the company a portfolio of assets valued at approximately $9.1 billion (based on the

149



Unaudited Pro Forma Condensed Consolidated Balance Sheet as of March 31, 2007) following the operating trust merger effective time. Such properties comprised 39% of total assets and 58% of the units that we owned or had an ownership interest in at March 31, 2007, including units under construction. In addition, these properties accounted for approximately 46% of our pro forma revenues and approximately 26% of our pro forma loss from operations for the year ended December 31, 2006, and approximately 39% of our pro forma revenues and approximately 37% of our pro forma loss from operations for the three months ended March 31, 2007. In addition, Parent may change its intentions with respect to such properties and cause other properties to be sold or distributed from time to time following the consummation of the mergers.


Policies

        The following is a discussion of our policies with respect to investment, disposition, financing and certain other activities. Our policies with respect to these activities are determined by our sole trustee, and may be waived, amended and revised from time to time at the discretion of our trustee without notice to, or vote of, the holders of any of our securities.

        We focus on apartment investment, management and operations. Our portfolio is concentrated in certain key markets in the United States: the Washington, D.C. metropolitan area; southern California; the San Francisco Bay Area; the New York metropolitan area; the Seattle metropolitan area; and the Boston metropolitan area. Our primary business objective is to maximize total return to MergerCo through appreciation in the value of our assets.

        We currently do not intend to acquire or develop any additional properties, but may invest or develop properties which may not be limited to any geographic area or product type or to a specified percentage of our assets, without any limit on the amount or percentage of its assets that may be invested in any one property, any one geographic area or any one asset class.

        We currently do not intend to, but may, (a) participate with third parties in property ownership, through joint ventures or other types of co-ownership; (b) invest in mortgages and other types of equity or debt real estate interests; (c) invest in securities of other REITs, securities of other entities engaged in real estate activities or securities of other issuers, including for the purpose of exercising control over such entities, and (d) acquire all or substantially all of the securities or assets of other REITs or similar entities.

        In our 2001 merger with the Smith partnership we agreed, for the benefit of the holders of the Smith partnership units that were converted into our Class A-1 common units in that merger, not to sell, exchange or otherwise dispose of, except in tax-free or tax-deferred transactions, any of the properties that were held by the Smith partnership or any interest therein. These restrictions, which are included in a tax protection agreement that is part of our declaration of trust, are effective until January 1, 2022. In addition, we have made other specified undertakings. If we sell any of the Smith partnership properties or any interest therein without satisfaction of certain conditions, engage in any merger that requires that the former holders of Smith partnership units who continue to hold our units recognize all or part of the gain that would be recognized by them for tax purposes upon a sale of any one or more of the Smith partnership properties, or repay borrowings relating to the Smith partnership properties, we may be liable for monetary damages for engaging in those actions. In addition, in the Smith partnership merger, we assumed the obligations of the Smith partnership under certain then existing tax protection agreements in favor of various holders of Smith partnership units. Under certain circumstances the operating trust may distribute properties without triggering the recognition of gain by

150


the contributing party, including certain qualifying distributions from and after the seventh anniversary of the contribution of those properties. The operating trust reserves the right to make such distributions, which if effected would correspondingly reduce the assets of the operating trust. We may dispose of any of the Smith partnership properties in the future.

        In connection with other acquisitions of properties in exchange for our units, we have entered into tax protection agreements with the contributing parties that acquired our units in such transactions. Those agreements, the terms of which vary from agreement to agreement, generally afford various protections to the holders of such units in connection with sales of the properties they contributed, or interests therein, transactions treated as sales of such properties for federal income tax purposes, debt refinancings, and certain other matters. We may also dispose of any of those assets in the future.

        We reserve the right to dispose of our properties, including by disposing of assets to entities which are directly or indirectly jointly controlled by affiliates of TS Fund VII and Lehman Brothers, subject to the provisions of any agreements to which we are a party in accordance with our Declaration of Trust.

        Parent received commitments for debt financing in an aggregate amount of up to $17.1 billion for the purpose of financing the mergers, funding reserves, refinancing a portion of company's existing debt, and for other costs and expenses related to the mergers. The lenders' commitment to provide the debt financing terminates on December 31, 2007, unless extended in accordance with its terms and is conditioned on the completion of the mergers and other customary conditions. The lenders have the right to terminate the debt commitment letter under certain circumstances, including if the buyer parties are entitled to terminate the merger agreement due to a breach of certain representations and warranties by the company or a material adverse effect with respect to the company. It is expected that an as yet to be determined portion of the permanent debt financing will consist of commercial mortgage-backed securities on terms to be agreed. It is anticipated that this debt financing (whether pursuant to the commitments or otherwise) will impose limitations on the incurrence of indebtedness. We may, from time to time, reduce the amount of our outstanding indebtedness by repaying or repurchasing a portion of such outstanding indebtedness, subject to certain restrictions contained in the terms of our outstanding indebtedness.

        The company is authorized to cause us to borrow money and to issue and guarantee debt as it deems necessary for the conduct of our activities. Such debt may be secured by mortgages, deeds of trust, liens or encumbrances on our properties or pledges of partnership or membership interests in the entities owning our properties. The company also may cause us to borrow money to enable us to make distributions, including distributions in an amount sufficient to permit the company, for so long as it qualifies as a REIT, to avoid the payment of any United States federal income tax. Pursuant to our 2001 merger agreement with the Smith partnership, we have agreed to maintain specified levels of borrowings outstanding with respect to the Smith partnership properties through January 1, 2022.

        We may, from time to time, make loans to others, invest in securities of other issuers for the purpose of exercising control and issue securities in exchange for property, or purchase our securities from our unitholders; provided that, prior to January 1, 2043, revocation of (or any action that would have the effect of revoking or terminating) the election by the operating trust to be treated as a "partnership" for federal income tax purposes shall be treated as a liquidation of the operating trust and shall be permitted only if the requisite vote, notice and absence of objection provided for in our declaration of trust have been satisfied. It is anticipated that the debt financing incurred in connection

151


with the mergers will impose limitations on our ability to make such loans, invest in such securities and issue such securities. We do not underwrite securities of other issuers.

        We do not presently intend to mail reports to the unitholders but currently are required to file quarterly, annual, and other periodic reports with the SEC, which are publicly available. See also "Risk Factors—The termination of registration of our Class A-1 common units under the Exchange Act would substantially reduce the information required to be publicly furnished by us and would make certain provisions of the Exchange Act no longer applicable to us" on page 37.


Trustee and Officers After the Mergers

        MergerCo or an assignee will be the sole trustee of the operating trust after the mergers. We currently anticipate that all of our existing executive officers will remain executive officers following the completion of the mergers. Parent has finalized Mr. Sellers' employment term sheet and is working with Mr. Sellers' to put in place a new incentive plan with the focus of retaining our current executive officers. No terms of any such plan have yet been determined. We have agreed in principle to the terms of a separation and general release agreement with Mr. Freeman pursuant to which Mr. Freeman has agreed to resign as the company's and our Chief Operating Officer effective December 31, 2007, but will continue to be employed through December 31, 2008. During the term of Mr. Freeman's continued employment, he will continue to be paid an annual base salary of $450,000. If none of the current executive officers remains employed by us following the mergers, it is anticipated that the associated severance costs would be approximately $14,958,461 based on a September 30, 2007 severance date. See "The Mergers—Interests of Our Trustees and Executive Officers in the Mergers" on page 69.

        The information required by Item 401 of Regulation S-K is incorporated herein by reference from "Part 1.—Management—Biographies of Senior Officers" from our Annual Report on Form 10-K for the year ended December 31, 2006, a copy of which is included as Attachment B to this prospectus/information statement.

        The company, as our sole trustee has been responsible for the oversight and management of us and has performed the day-to-day management of the operating trust through its officers. No compensation is paid to the company for acting as trustee. Each officer of the company holds the same officer position with us and is compensated for his or her service to the company and us, considered as a single enterprise.

        The information concerning the historical compensation of the executive officers as required by Item 402 of Regulation S-K is incorporated herein by reference from "Compensation Discussion and Analysis," "Post-Employment Payments," "Tax Implications of Compensation," "2006 Executive Compensation" and "Compensation Committee Report" from the company's definitive proxy statement for the May 16, 2007 annual meeting of shareholders.

ACCOUNTING TREATMENT

        The operating trust merger will be accounted for using the purchase method of accounting. Although the operating trust will be the surviving legal entity, MergerSub will be treated as the acquiror. Under this method of accounting, the operating trust assets and liabilities will be recorded at their respective fair values as of the closing date of the operating trust merger. MergerSub was a newly created entity and therefore has no historical financial statements. Financial statements of the operating trust issued after the operating trust merger will reflect these values, but will not be restated retroactively.

154



DISSENTERS' RIGHTS OF APPRAISAL

        The merger agreement provides holders of our Class A-1 common units with appraisal rights in accordance with the applicable procedures under Maryland law. The availability and exercise of appraisal rights are conditioned on strict adherence to the applicable provisions of the MGCL. Each unitholder desiring to exercise appraisal rights should refer to Title 3, Subtitle 2 of the MGCL, a copy of which is attached as Annex C to this prospectus/information statement, for a complete statement of the steps which must be followed in connection with the exercise of those rights. The following summary of the rights of objecting unitholders does not purport to be a complete statement of the procedures to be followed by those of our unitholders desiring to exercise their appraisal rights.

        A holder of the Class A-1 common units will be entitled to demand and receive payment of the fair value of its units from us instead of receiving $60.75 in cash per unit or Series O preferred units in the operating trust merger. However, a unitholder who wants to receive fair value for its units must follow specific procedures required by the MGCL. Such unitholder must:

        Any unitholder who fails to comply with the requirements described above will be bound by the terms of the operating trust merger and will not have any right to the appraised value of the Class A-1 common units. Written objections to the operating trust merger should be addressed to Archstone-Smith Operating Trust, 9200 East Panorama Circle, Suite 400, Englewood, Colorado 80112, Attention: Legal Department.

        We are required to promptly notify each objecting unitholder in writing of the date of acceptance of the Articles of Merger for record by the SDAT. Under the MGCL, we are entitled to send a written offer, along with certain information, to each objecting unitholder to pay for its units at what we consider to be the fair value thereof. Within 50 days after the SDAT accepts the Articles of Merger for record, either we or any objecting unitholder who has not received payment for its units may petition a court of equity in the appropriate county in Maryland for an appraisal to determine the fair value of the units.

        We do not presently intend to file an appraisal petition and unitholders seeking to exercise appraisal rights should not assume that we will file such a petition or that we will initiate any negotiations with respect to the fair value of such units. Accordingly, Class A-1 common unitholders who desire to have an appraisal to determine the fair value of their units should initiate any petitions necessary for the perfection of their appraisal rights within the time periods and in the manner prescribed in the MGCL.

        If the court finds that an objecting unitholder is entitled to an appraisal of its units, the court is required to appoint three disinterested appraisers to determine the fair value of its units on terms and conditions the court determines proper. The appraisers must, within 60 days after appointment (or such longer period as the court may direct), file with the court and mail to each party to the proceeding their report stating their conclusion as to the fair value of such units. "Fair value" is determined as of the close of business on the day Archstone-Smith Trust approves the operating trust merger and does not include any appreciation or depreciation which directly or indirectly results from the operating trust merger or from its proposal.

155



        Within 15 days after the filing of the report, any party may object to such report and request a hearing on it. The court must, upon motion of any party, enter an order either confirming, modifying or rejecting such report and, if confirmed or modified, enter judgment for the appraised value of the units. If the appraisers' report is rejected, the court may determine the fair value of the units of the objecting unitholders or may remit the proceeding to the same or other appraisers. Any judgment entered pursuant to a court proceeding shall include interest from the date the operating trust merger is approved by Archstone-Smith Operating Trust. Costs of the proceeding shall be determined by the court and may be assessed against us or, under certain circumstances, the objecting unitholder, or both.

        At any time after the filing of a petition for appraisal, the court may require objecting unitholders to submit their certificates, if any, evidencing their Class A-1 common units to the clerk of the court for notation of the pendency of the appraisal proceeding.

        A unitholder demanding payment for units has no right to receive any dividends or distributions payable to unitholders of record after the close of business on the date the operating trust merger is approved and shall cease to have any right as our unitholder of with respect to such units except the right to receive payment of the fair value thereof.

        Failure to comply with all of the procedures set forth in Title 3, Subtitle 2 of the MGCL will result in the loss of a unitholder's statutory appraisal rights. In view of the complexity of Title 3, Subtitle 2 of the MGCL, Class A-1 common unit holders who wish to exercise their appraisal rights should consult their legal advisors.

156

EXPERTS

        The consolidated financial statements and schedules of Archstone-Smith Operating Trust as of December 31, 2006 and 2005, and for each of the years in the three-year period ended December 31, 2006, and management's assessment of the effectiveness of internal control over financial reporting as of December 31, 2006 have been incorporated by reference herein and in the registration statement in reliance upon the reports of KPMG LLP, independent registered public accounting firm, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing.

        The audit report on management's assessment of the effectiveness of internal control over financial reporting and the effectiveness of internal control over financial reporting as of December 31, 2006, contains an explanatory paragraph that states Archstone-Smith Operating Trust acquired DeWAG Deutsche WohnAnlage GmbH ("DeWAG") during July 2006, and has excluded from its assessment of the effectiveness of Archstone-Smith Operating Trust's internal control over financial reporting as of December 31, 2006. DeWAG's internal control over financial reporting associated with total assets of $857.0 million and total revenues of $27.7 million included in the consolidated financial statements of Archstone-Smith Operating Trust as of and for the year ended December 31, 2006. Our audit of internal control over financial reporting of Archstone-Smith Operating Trust also excluded an evaluation of the internal control over financial reporting of DeWAG.

        With respect to the unaudited interim financial information of Archstone-Smith Operating Trust for the periods ended March 31, 2007 and 2006, incorporated by reference herein, the independent registered public accounting firm has reported that they applied limited procedures in accordance with professional standards for a review of such information. However, their separate report included in Archstone-Smith Operating Trust's quarterly report on Form 10-Q for the quarter ended March 31, 2007, incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. The independent registered public accounting firm is not subject to the liability provisions of Section 11 of the Securities Act of 1933 for their report on the unaudited interim financial information because their report is not a "report" or a "part" of the registration statement prepared or certified by the accountants within the meaning of Sections 7 and 11 of the Securities Act of 1933.

ARCHSTONE-SMITH OPERATING TRUST

PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

        The accompanying unaudited pro forma condensed consolidated financial statements set forth the historical financial information of Archstone-Smith Operating Trust ("Operating Trust") and River Trust Acquisition (MD), LLC ("Operating Trust MergerSub") as a consolidated entity, giving effect to the proposed Merger as if it had occurred on the dates indicated below and after giving effect to certain pro forma adjustments. The Merger will be accounted for using the purchase method of accounting in accordance with Statement of Financial Accounting Standards No. 141, "Business Combinations." The allocation of the purchase price reflected in the pro forma condensed consolidated balance sheet is preliminary and is subject to change. We can give no assurance that when the audit with respect to such allocation of purchase price is completed the financial information will not change or that any change will not be material. The Operating Trust MergerSub is considered the acquirer for accounting purposes. Under the terms of the Merger Agreement each Class A-1 Common Unit will be converted into the right to receive (a) one newly-issued Series O Preferred Unit, or (b), at the election of the holder, cash consideration of $60.75. The Class A-2 Common Units, which are all held by Archstone-Smith Trust, shall remain outstanding. A cash distribution will be made to Archstone-Smith Trust to facilitate cancellation and retirement of its Common Shares. We have assumed that the Parent has elected to replace each Series I Preferred Unit with a substantially identical Series I Preferred Unit. Under the terms of the Merger Agreement, outstanding Equity Awards to employees will become fully vested and cash will be paid to the extent that the awards are "in the money" based on a $60.75 share price.

        In addition to the proposed Merger, the accompanying unaudited pro forma condensed consolidated financial statements also present the pro forma impact of certain planned asset distributions that the buyer parties have informed us they intend to consummate immediately after the effective time of the Merger. The intention of the buyer parties is subject to change with respect to such asset distributions and other assets may be sold or distributed from time to time.

        The accompanying unaudited pro forma condensed consolidated balance sheet is presented as if the Merger and the related transactions described above had occurred on March 31, 2007. The accompanying unaudited pro forma condensed consolidated statements of operations for the three months ended March 31, 2007 and year ended December 31, 2006 are presented as if the Merger and the related transactions described above had been consummated on January 1, 2006. It is unknown how many Class A-1 Common Units will be converted into Series O Preferred Units. In these pro forma financial statements we have assumed 100% of Class A-1 Common Units will be converted into Series O Preferred Units. In the opinion of management, all material adjustments necessary to reflect the effects of these transactions and related assumptions have been made.

        The pro forma condensed consolidated financial statements should be read in conjunction with the historical financial statements of the Operating Trust, as set forth in the quarterly report on Form 10-Q for the three months ended March 31, 2007 and the 2006 annual report on Form 10-K, both of which are incorporated by reference into this document. See "Where You Can Find More Information" on page 163. The pro forma unaudited condensed consolidated financial statements are presented for informational purposes only and are not necessarily indicative of what the actual consolidated financial position or results of operations of the Operating Trust would have been for the periods presented, nor do they purport to represent the forecasted results of future periods.

The pro forma adjustment is preliminary and subject to change. It is anticipated that additional assets may be transferred over time into Parent-owned entities subject to applicable debt covenants, including the 85% total debt (which includes for this purpose the total liquidation preference of the Series O preferred units and any other parity preferred units) to total assets ratio specificed under the terms of the Series O Preferred Units. The specific assets and financial impact of any such future transfers are not known at this time.

OPERATING TRUST

NOTES TO PRO FORMA CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)

For the Three Months Ended March 31, 2007 and Year Ended December 31, 2006

(a)
For the Operating Trust, reflects the condensed historical statements of earnings (excluding discontinued operations) for the three months ended March 31, 2007 and the year ended December 31, 2006. The Operating Trust MergerSub did not exist at March 31, 2007 and therefore has no historical financial statements.

(b)
The estimated quantifiable increase in real estate taxes is expected to be approximately $9 million quarterly or $37 million annually as a result of the transaction.

(c)
Reflects estimated pro forma depreciation expense resulting from the transaction, based on the estimated stepped-up depreciable basis of the assets. The land/building split is based on our good faith estimate of the relative values of these two components. Amounts are calculated below in thousands.

Calculated increase in asset value
(excluding real estate held for sale)

Reflects the assumed increase in interest expense due to the new debt financing and also considers the assumed repayment of certain debt instruments. The interest rate related to new variable rate debt was computed based on LIBOR for the historical period presented plus the spread specified in the acquiror's financing commitment and considering debt issuance costs. The amount of interest capitalized during the construction period as part of the cost of the apartment communities under development is assumed to increase as a result of the higher effective interest rate.

(e)
In our historical financial statements we have recognized stock compensation expense and capitalized a portion of the compensation expense related to development and other qualifying investment activities. Although our stock based awards will become fully vested and redeemed as a result of change in control provisions, we have not included a reduction of compensation expense as we believe our long term incentive plan will be replaced with another similar means of compensating officers and employees.

(f)
Our Chief Executive Officer has agreed to enter into a new employment contract that will supersede his existing employment arrangement with the Operating Trust. For this purpose, we have assumed that amounts related to the new employment arrangement approximate the expense recorded in historical financial statements and therefore no adjustment is reflected.

(g)
Reflects the assumed distributions on Series O Preferred Units (dollars in thousands) at the stated distribution rate of 6% per annum (determined without regard to the cumulative amount of income allocated to the holders of Series O Preferred Units). To the extent there is insufficient cash to fund any distribution or to the extent the cumulative income allocable to holders of our Series O Preferred Units is less than the distributions accruing at the stated rate, the excess amount will be accrued as a contingent cash obligation for accounting purposes. The full accrued amount will be payable only if and to the extent of the cumulative income allocated to holders of our Series O Preferred Units in future periods. We do not anticipate that distributions on our Series O Preferred Units initially will be paid in cash, because there will not be income from operations to be allocated to the holders of the Series O Preferred Units. The actual number of unitholders which will elect to receive Series O Preferred Units in exchange for outstanding Class A-1 Common Units will not be known until shortly before the consummation of the Merger.

(h)
As a result of the transaction described, it is assumed that quarterly distributions on Common Units recorded in our historical results would not have been paid.

(i)
Represents assumed adjustment to basic and diluted weighted average Common Units outstanding for (i) Class A-1 Common Units since they will be redeemed or converted to a new Series O Preferred Unit which will not be a common stock equivalent, (ii) convertible debt (due to assumed payoff) and (iii) options that will be settled for cash. Note that only the conversion of the Class A-1 Common Units affects the basic weighted average units outstanding.

(j)
Reflects the income statement impact of the anticipated distribution of certain properties to Archstone-Smith Trust. The pro forma adjustment is preliminary and subject to change. It is anticipated that additional assets may be transferred over time into Parent-owned entities subject to applicable debt covenants, including the 85% total debt (which includes for this purpose the total liquidation preference of the Series O preferred units and any other parity preferred units) to total assets ratio specificed under the terms of the Series O Preferred Units. The specific assets and the financial impact of any such future transfers are not known at this time.
(k)
Following is a calculation of the ratio of earnings to fixed charges and preferred distributions which excludes earnings and interest included in discontinued operations. Note that pro forma interest expense has been reflected as if the debt were outstanding during the entire period

destroyed Share Certificate or Unit Certificate the applicable Cash Consideration payable in respect thereof pursuant to this Agreement.

         (e)  Nothing in this Section 7.04 or elsewhere in this Agreement shall prevent the Company Board or a Special Committee from (i) at any time prior to obtaining the Company Shareholder Approval and other than in response to an Acquisition Proposal, effecting a Change in Recommendation if the Company Board or a Special Committee determines in good faith, after consultation with its outside legal counsel, that failure to take such action would be reasonably likely to be inconsistent with its duties to the Company Shareholders under applicable Law or (ii) taking and disclosing to the Company Shareholders a position contemplated by Rule 14d-9 or Rule 14e-2(a) promulgated under the Exchange Act with respect to an Acquisition Proposal or from making any required disclosure to the Company Shareholders under applicable Law, including Rule 14d-9 promulgated under the Exchange Act or Item 1012(a) of Regulation M-A; provided, however, that such disclosure shall be deemed to be a Change in Recommendation if not accompanied by an express public re-affirmation of the Company Recommendation and the Operating Trust Recommendation; provided, further, that none of the Company, the Company Board or a Special Committee shall be permitted to recommend that the Company Shareholders tender any securities in connection with any tender or exchange offer (or otherwise approve, endorse or recommend any Acquisition Proposal) or withdraw or modify the Company Recommendation or the Operating Trust Recommendation, unless in each case such tender or exchange offer constitutes a Superior Proposal and in connection therewith, effects a Change in Recommendation.

or in respect of such judgments, fines, penalties or amounts paid in settlement) resulting therefrom; and (ii) promptly pay on behalf of each of the Indemnified Parties, to the fullest extent authorized or permitted by applicable Law, as now or hereafter in effect, any Indemnifiable Expenses incurred in defending, serving as a witness with respect to or otherwise participating in any Claim in advance of the final disposition of such Claim, including payment on behalf of or advancement to the Indemnified Party of any Indemnifiable Expenses incurred by such Indemnified Party in connection with enforcing any rights with respect to such indemnification and/or advancement, including all reasonable attorneys' fees and expenses, in each case without the requirement of any bond or other security, but subject to Parent's or the Surviving Entity's, as applicable, receipt of an undertaking by or on behalf of such Indemnified Party, if required by applicable Law, to repay such Indemnifiable Expenses if it is ultimately determined under applicable Laws that such Indemnified Party is not entitled to be indemnified); provided, however, that neither Parent nor the Surviving Entity shall be liable for any settlement effected without Parent's or the Surviving Entity's written consent and shall not be obligated to pay the fees and expenses of more than one counsel (selected by a plurality of the applicable Indemnified Parties) for all Indemnified Parties in any jurisdiction with respect to any single Claim except to the extent that two or more of such Indemnified Parties shall have conflicting interests in the outcome of such action. The indemnification and advancement obligations of Parent and the Surviving Entity pursuant to this Section 7.06(a) shall extend to acts or omissions occurring at or before the Company Merger Effective Time and any Claim relating thereto (including with respect to any acts or omissions occurring in connection with the approval of this Agreement and the consummation of the transactions contemplated hereby, including the consideration and approval thereof and the process undertaken in connection therewith and any Claim relating thereto). All rights to indemnification and advancement conferred hereunder shall continue as to a person who has ceased to be a director or officer of the Company or the U.S. Subsidiaries or the Foreign Subsidiaries after the date hereof and shall inure to the benefit of such person's heirs, executors and personal and legal representatives. For purposes of this Section 7.06(a): (x) the term "Claim" means any threatened, asserted, pending or completed Action, whether instituted by any party hereto, any Governmental Authority or any other party, that any Indemnified Party in good faith believes might lead to the institution of any such Action, whether civil, criminal, administrative, investigative or other, including any arbitration or other alternative dispute resolution mechanism, arising out of or pertaining to matters that relate to such Indemnified Party's duties or service as a director or officer of the Company or any of the U.S. Subsidiaries or the Foreign Subsidiaries, at or prior to the Company Merger Effective Time at the request of the Company or any of the U.S. Subsidiaries or the Foreign Subsidiaries; and (y) term "Indemnifiable Expenses" means reasonable attorneys' fees and all other reasonable costs, expenses and obligations (including experts' fees, travel expenses, court costs, retainers, transcript fees, duplicating, printing and binding costs, as well as telecommunications, postage and courier charges) paid or incurred in connection with investigating, defending, being a witness in or participating in (including on appeal), or preparing to investigate, defend, be a witness in or participate in, any Claim for which indemnification is authorized pursuant to this Section 7.06(a), including any Action relating to a claim for indemnification or advancement brought by an Indemnified Party. Neither Parent nor the Surviving Entity shall settle, compromise or consent to the entry of any judgment in any Claim in respect of which indemnification has been or could be sought by such Indemnified Party hereunder unless (i) such settlement, compromise or judgment includes an unconditional release of such Indemnified Party from all liability arising out of such Claim, (ii) such Indemnified Party otherwise consents thereto, or (iii) Parent or the Surviving Entity acknowledges that such Claim is subject to this Section 7.06.

         (b)  For a period of six (6) years from the Company Merger Effective Time, the charter and bylaws or other organizational documents of the Surviving Entity and the U.S. Subsidiaries and the Foreign Subsidiaries shall contain provisions no less favorable with respect to indemnification than are set forth in the Company Articles, Company Bylaws, Operating Trust Articles, Operating Trust Bylaws

A-56



or the applicable organizational documents of the Subsidiaries, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Company Merger Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Company Merger Effective Time, were directors, officers, trustees, employees, agents, or fiduciaries (including fiduciaries under or with respect to any employee benefit plan (within the meaning of Section 3(3) of ERISA)) of the Company or any of its U.S. Subsidiaries or the Foreign Subsidiaries, unless such modification shall be required by Law and then only to the minimum extent required by Law.

         (c)  Parent or the Surviving Entity shall maintain for a period of at least six (6) years, policies of directors' and officers' liability insurance and employed lawyer liability insurance with respect to claims arising from facts or events that occurred on or before the Company Merger Effective Time, including in respect of the transactions contemplated by this Agreement. Such policies shall provide for at least $50,000,000 of coverage for directors' and officers' liability and $5,000,000 for employed lawyer liability and shall contain other terms and conditions which are, in the aggregate, not less advantageous to the insured persons than the policies maintained by the Company, the Operating Trust, the U.S. Subsidiaries and the Foreign Subsidiaries as of the date hereof. There shall be no gaps or lapses of coverage with respect to matters occurring before the Company Merger Effective Time; provided, that the aggregate premium payable for such insurance shall not exceed the amount set forth on Schedule 7.06(c) (such amount the "Maximum Premium"). If the Company is unable to obtain the insurance described in the first sentence of this Section 7.06(c) for an amount less than or equal to the Maximum Premium, Parent or the Surviving Company shall obtain as much comparable insurance as possible for an amount equal to the Maximum Premium. Notwithstanding the preceding, Parent and the Surviving Entity may meet their obligations pursuant to this Section 7.06(c) by purchasing a "tail policy" providing coverage in the amounts specified above and on other terms and conditions which are, in the aggregate, not less advantageous to the insured persons than the policies maintained by the Company, the Operating Trust, the U.S. Subsidiaries and the Foreign Subsidiaries as of the date hereof such. If Parent or the Surviving Entity purchase a tail policy pursuant to the immediately preceding sentence, Parent shall, and shall cause the Surviving Entity or its successors or assigns to, maintain such policy in full force and effect, and continue to honor all obligations thereunder.

         (d)  If the Surviving Entity or any of its respective successors or assigns (i) consolidates with or merges with or into any other person and shall not be the continuing or Surviving Entity, partnership or other entity of such consolidation or merger or (ii) liquidates, dissolves or winds-up, or transfers or conveys all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Surviving Entity assumes the obligations set forth in this Section 7.06.

         (e)  Parent shall cause the Surviving Entity to perform all of the obligations of the Surviving Entity under this Section 7.06 and the parties acknowledge and agree that Parent guarantees the payment and performance of the Surviving Entity's obligations pursuant to this Section 7.06.

        Section 7.07    Further Action; Reasonable Efforts.

         (a)  Except to the extent otherwise provided in Section 7.01, upon the terms and subject to the conditions of this Agreement, each of the parties hereto shall (i) make promptly its respective filings and thereafter make any other required submissions, under any applicable antitrust or competition laws, and any other Law with respect to this Agreement and the Mergers, if required, and (ii) use its commercially reasonable efforts to take, or cause to be taken, all appropriate action, and to do, or cause to be done, all things necessary, proper or advisable under applicable Laws to consummate and make effective the Mergers, and the other transactions contemplated by this Agreement, including using its commercially reasonable efforts to obtain all Permits, consents, approvals, authorizations, qualifications and orders of Governmental Authorities with the Company and the U.S. Subsidiaries and

Each party shall keep the other apprised of the content and status of any communications with, and communications from, any Governmental Authority with respect to the transactions contemplated by this Agreement. To the extent practicable and permitted by a Governmental Authority, each party hereto shall permit representatives of the other party to participate in meetings and calls with such Governmental Authority. None of the parties shall consent to any voluntary extension of any statutory deadline or waiting period or to any voluntary delay of the consummation of the transactions contemplated by this Agreement at the behest of any Governmental Authority without the consent of the other party, which consent shall not be unreasonably withheld or delayed.

         (c)  Each of the parties hereto agrees to cooperate and use its reasonable best efforts to defend through litigation on the merits any Action, including administrative or judicial Action, asserted by any party in order to avoid the entry of, or to have vacated, lifted, reversed, terminated or overturned any decree, judgment, injunction or other order (whether temporary, preliminary or permanent) that in whole or in part restricts, delays, prevents or prohibits consummation of the Company Merger, including by vigorously pursuing all available avenues of administrative and judicial appeal.

         (d)  Each of the Buyer Parties, on the one hand, and the Company Parties, on the other hand, shall use their respective commercially reasonable efforts to obtain any Third Party consents (i) necessary, proper or advisable to consummate the transactions contemplated by this Agreement, (ii) disclosed in the Disclosure Schedule or (iii) required to prevent a Company Material Adverse Effect from occurring prior to the Company Merger Effective Time. In the event that any Company Party shall fail to obtain any Third Party consent described above, the Company Parties shall use their commercially reasonable efforts, and shall take such actions as are reasonably requested by Parent, to minimize any adverse effect upon the Company Parties and the Buyer Parties and their respective businesses resulting, or which could reasonably be expected to result, after the Company Merger Effective Time, from the failure to obtain such consent. Notwithstanding anything to the contrary in this Agreement, in connection with obtaining any approval or consent from any Person (other than a Governmental Authority) with respect to any transaction contemplated by this Agreement, (i) unless required by the applicable agreement, without the prior written consent of Parent, neither the Company nor any of the U.S. Subsidiaries or Foreign Subsidiaries shall pay or commit to pay to such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation due to such Person and (ii) none of the Buyer Parties or their respective affiliates shall be required to pay or commit to pay such Person whose approval or consent is being solicited any cash or other consideration, make any commitment or incur any liability or other obligation.

A-58



From and after the Company Merger Effective Time, the Surviving Entity shall pay or cause to be paid, without deduction or withholding from any consideration or amounts payable to holders of the Company Common Shares, Company Share Options, Company Restricted Share Units and, all Transfer Taxes.

        Section 7.09    Public Announcements.    The parties hereto agree that no public release or announcement concerning the transactions contemplated by this Agreement (including the Mergers) shall be issued by a party without the prior consent of the other parties (which consent shall not be unreasonably withheld), except as such release or announcement may be required by Law or the rules or regulations of any securities exchange, in which case the party required to make the release or announcement shall use its reasonable best efforts to allow the other parties reasonable time to comment on such release or announcement in advance of such issuance. The parties have agreed upon the form of a joint press release announcing the Mergers and the execution of this Agreement.

        Section 7.10    Cooperation with Financing.

         (a)  Parent shall use its reasonable best efforts to arrange the Debt Financing on the terms and conditions described in the Debt Commitment Letter, including using reasonable best efforts to (i) negotiate definitive agreements with respect thereto on terms and conditions contained therein and (ii) to satisfy all conditions applicable to the Buyer Parties in such definitive agreements that are within their control. In the event any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter, Parent shall use its reasonable best efforts to arrange to obtain any such portion from alternative sources on comparable or more favorable terms to Parent (as determined in the reasonable judgment of Parent) as promptly as practicable following the occurrence of such event. Parent shall give the Company prompt notice of any material breach by any party of the Debt Commitment Letter or any termination of the Debt Commitment Letter. Parent shall keep the Company informed on a reasonably current basis in reasonable detail of the status of its efforts to arrange the Debt Financing and shall not permit any material amendment or modification to be made to, or any waiver of any material provision or remedy under, the Debt Commitment Letter if such amendment would or would be reasonably expected to materially and adversely affect or delay in any material respect Parent's ability to consummate the transactions contemplated by this Agreement, without first obtaining the Company's prior written consent (not to be unreasonably withheld or delayed). For the avoidance of doubt, if the Debt Financing (or any alternative financing) has not been obtained, the Buyer Parties shall continue to be obligated to consummate the Mergers on the terms contemplated by this Agreement and subject only to the satisfaction or waiver of the conditions set forth in Sections 8.01 and 8.02 of this Agreement and to Parent's rights under Section 9.01, regardless of whether the Buyer Parties have complied with all of their other obligations under this Agreement (including their obligations under this Section 7.10).

         (b)  The Company agrees to provide, and shall cause the U.S. Subsidiaries and the Foreign Subsidiaries and its and their Representatives to provide, all reasonable cooperation in connection with the arrangement of the Financing as may be reasonably requested by Parent (provided that such requested cooperation does not unreasonably interfere with the ongoing operations of the Company and the U.S. Subsidiaries and the Foreign Subsidiaries), including (i) participation in meetings, drafting sessions and due diligence sessions, (ii) furnishing Parent and its financing sources with financial and other pertinent information regarding the Company and the U.S. Subsidiaries and the Foreign Subsidiaries as may be reasonably requested by Parent, (iii) assisting Parent and its financing sources in the preparation of (A) an offering document for any Financing to be raised to complete the Mergers and (B) materials for rating agency presentations, (iv) reasonably cooperating with the marketing efforts of Parent and its financing sources for any Financing to be raised by Parent to complete the Mergers, (v) forming new direct or indirect subsidiaries and transferring assets thereto prior to or after the Operating Trust Merger Effective Time (any such transfer to be a Requested Transaction and be subject to the terms and conditions of Section 2.06 hereof), (vi) using reasonable best efforts to obtain

A-59



accountants' comfort letters, legal opinions, appraisals, surveys, title insurance, estoppels and certificates from tenants, lenders and ground lessors and other documentation and items relating to the Financing as reasonably requested by Parent, (vii) providing and executing documents as may be reasonably requested by Parent, and (viii) cooperating in connection with the repayment or defeasance of any Indebtedness of the Company or any of the U.S. Subsidiaries or Foreign Subsidiaries, including delivering such payoff, defeasance or similar notices under any existing mortgage or mezzanine loans of the Company or any U.S. Subsidiary or Foreign Subsidiary as reasonably requested by Parent. Parent shall, promptly upon request by the Company, reimburse the Company for all reasonable out-of-pocket costs incurred by the Company, its U.S. Subsidiaries and its Foreign Subsidiaries and their Representatives in connection with such cooperation. The Buyer Parties shall, on a joint and several basis, indemnify and hold harmless the Company, its U.S. Subsidiaries and its Foreign Subsidiaries and their respective Representatives from and against any and all liabilities, losses, damages, claims, costs, expenses, interest, awards, judgments and penalties suffered or incurred by them in connection with the arrangement of the Financing and any information utilized in connection therewith (other than historical information relating to the Company or its U.S. Subsidiaries or Foreign Subsidiaries). Notwithstanding anything to the contrary, the condition set forth in Section 8.02(b), as it applies to the Company's obligations under this Section 7.10(b), shall be deemed satisfied unless the Financing (or any alternative financing) has not been obtained primarily as a result of the Company's or the U.S. Subsidiaries' or Foreign Subsidiaries willful and material breach of its obligations under this Section 7.10(b).

         (c)  All non-public or otherwise confidential information regarding the Company obtained by Parent or its Representatives pursuant to paragraph (b) above shall be kept confidential in accordance with the Confidentiality Agreement.

         (a)  Except as otherwise set forth in Sections 2.06, 7.08 and 7.10(b) and this Section 9.04, all expenses (including fees and expenses payable to Representatives) incurred by any party to this Agreement or its Affiliates on its behalf in connection with this Agreement or the transactions contemplated by this Agreement ("Expenses") shall be paid by the party incurring such expenses, whether or not the Mergers are consummated.

         (b)  The Company agrees that if this Agreement shall be terminated:

A-65


         (c)  Parent agrees that if this Agreement shall be terminated by the Company pursuant to Section 9.01(f), then Parent shall pay to the Company the Company Expenses within three (3) Business Days of the Termination Date in immediately available funds to an account directed by the Company.

         (d)  For the purposes of this Agreement:

         (e)  Each of the parties hereto acknowledges that the agreements contained in this Section 9.04 are an integral part of the transactions contemplated by this Agreement. In the event that the Company shall fail to pay the Company Termination Fee or the Parent Expenses when due or Parent shall fail to pay the Company Expenses when due, the Company or Parent, as the case may be, shall reimburse the other party for all reasonable costs and expenses actually incurred or accrued by such other party (including reasonable fees and expenses of counsel) in connection with the collection under and enforcement of this Section 9.04. If payable, none of the Company Termination Fee, the Parent Expenses, or the Company Expenses shall be payable more than once pursuant to this Agreement.

          (f)  Each of Parent and the Company acknowledges that the agreements set forth in this Section 9.04 are an integral part of the transactions contemplated by this Agreement, and that without these agreements, the other party would not enter into this Agreement. Accordingly, if the Company or Parent, as the case may be, fails to timely pay any amount due pursuant to this Section 9.04, and, in order to obtain the payment, Parent or the Company, as the case may be, commences a suit which results in a judgment against the other party for the payment set forth in this Section 9.04, such paying party shall pay the other party its reasonable and documented costs and expenses (including reasonable and documented attorneys' fees) in connection with such suit, together with interest on such amount at

A-66



the prime rate as reported in The Wall Street Journal in effect on the date such payment was required to be made through the date of payment.

         (g)  Notwithstanding anything to the contrary in this Agreement, in the event of a termination of this Agreement in connection with which a Company Termination Fee is payable to Parent or, in the case of Section 9.04(b)(ii), the Parent Expenses are payable to Parent, payment of such Company Termination Fee or Parent Expenses, as the case may be, by the Company pursuant to this Section 9.04 shall be the sole and exclusive remedy of Parent and its subsidiaries and Affiliates against the Company, its subsidiaries and any of their respective former, current, or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents for the loss suffered as a result of the failure of the Merger to be consummated, and upon payment of such amounts, none of the Company, its subsidiaries or any of their respective former, current, or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates or agents shall have any further liability or obligation relating to or arising out of this Agreement or the transactions contemplated by this Agreement (except that the Company shall also be obligated with respect to Section 9.04(f)).

        Section 9.05    Escrow of Company Expenses.

         (a)  To the extent that the Company Parties recover the Company Expenses pursuant to Section 9.04(c) and/or money damages pursuant to and subject to Section 10.06 and the Guarantees (collectively, the "Damages Amount"), Parent shall instruct the escrow agent to pay to the Operating Trust from the Damages Amount deposited into escrow in accordance with the next sentence, an amount equal to the lesser of (i) the Damages Amount and (ii) the sum of (A) the maximum amount that can be paid to the Operating Trust without causing the Company to fail to meet the requirements of Sections 856(c)(2) and 856(c)(3) of the Code determined as if the payment of such amount did not constitute income described in Sections 856(c)(2)(A)-(H) or 856(c)(3)(A)-(I) of the Code ("Qualifying Income"), as determined by the Company's independent certified public accountants, plus (B) in the event the Company receives either (A) a letter from the Company's counsel indicating that the Company has received a ruling from the IRS described in Section 9.05(b) or (2) an opinion from the Company's outside counsel as described in Section 9.05(b), an amount equal to the Damages Amount less the amount payable under clause (A) above. To secure Parent's obligation to pay these amounts, Parent shall deposit into escrow an amount in cash equal to the Damages Amount with an escrow agent selected by Parent and on such terms (subject to Section 9.05(b)) as shall be mutually agreed upon by the Operating Trust, Parent and the escrow agent. Subject to the terms of Section 10.06 and the Guarantees, the payment or deposit into escrow of the Damages Amount pursuant to this Section 9.05 shall be made at the time Parent is obligated to pay the Operating Trust such amount pursuant to Section 10.06 and the Guarantees by wire transfer or bank check.

         (b)  The escrow agreement shall provide that the Damages Amount in escrow or any portion thereof shall not be released to the Operating Trust unless the escrow agent receives any one or combination of the following: (i) a letter from the Company's independent certified public accountants indicating the maximum amount that can be paid by the escrow agent to the Operating Trust without causing the Company to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code determined as if the payment of such amount did not constitute Qualifying Income or a subsequent letter from the Company's accountants revising that amount, in which case the escrow agent shall release such amount to the Company, or (ii) a letter from the Company's counsel indicating that the Company received a ruling from the IRS holding that the Damages Amount would either constitute Qualifying Income or would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code (or alternatively, the Company's outside counsel has rendered a legal opinion to the effect that the receipt by the Operating Trust of the Damages Amount would constitute Qualifying Income, would be excluded from gross income within the meaning of Sections 856(c)(2) and (3) of the Code or would not otherwise disqualify Company as a REIT), in which case the escrow agent shall

A-67



release the remainder of the Damages Amount to the Operating Trust. Parent agrees to amend this Section 9.05 at the reasonable request of the Company in order to (x) maximize the portion of the Damages Amount that may be distributed to the Operating Trust hereunder without causing the Company to fail to meet the requirements of Sections 856(c)(2) and (3) of the Code, (y) improve the Company's chances of securing a favorable ruling described in this Section 9.05(b), or (z) assist Parent in obtaining a favorable legal opinion from its outside counsel as described in this Section 9.05(b). The escrow agreement shall also provide that any portion of the Damages Amount held in escrow for five years shall be released by the escrow agent to Parent. Any costs and expenses of the escrow agent shall be borne solely by the Company.

        Section 9.06    Waiver.    At any time prior to the Company Merger Effective Time, the Company, on the one hand, and Parent, on the other hand, may (a) extend the time for the performance of any obligation or other act of the other party, (b) waive any inaccuracy in the representations and warranties of the other party contained herein or in any document delivered pursuant hereto, and (c) waive compliance with any agreement of the other party or any condition to its own obligations contained herein. Any such extension or waiver shall be valid if set forth in an instrument in writing signed by the Company (on behalf of the Company Parties) or Parent (on behalf of the Buyer Parties), as applicable. The failure of any party to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of those rights.


ARTICLE X
GENERAL PROVISIONS

        Section 10.01    Non-Survival of Representations and Warranties.    The representations and warranties in this Agreement and in any certificate delivered pursuant hereto shall terminate at the Company Merger Effective Time.

        Section 10.02    Notices.    All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given upon receipt) by delivery in person, by prepaid overnight courier (providing proof of delivery), by facsimile or by registered or certified mail (postage prepaid, return receipt requested) to the respective parties at the following addresses or facsimile numbers (or at such other address for a party as shall be specified in a notice given in accordance with this Section 10.02):

A-68


        Section 10.03    Severability.    If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law or public policy or the application of this Agreement to any person or circumstance is invalid or incapable of being enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. To such end, the provisions of this Agreement are agreed to be severable. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

        Section 10.04    Amendment.    This Agreement may be amended by the parties hereto by action taken by their respective board of directors (or similar governing body or entity) at any time prior to the Company Merger Effective Time; provided, however, that, after approval of the Company Merger by the shareholders of the Company, no amendment may be made without further shareholder approval which, by Law or in accordance with the rules of the NYSE, requires further approval by such

A-69



shareholders. This Agreement may not be amended except by an instrument in writing signed by the parties hereto.

        Section 10.05    Entire Agreement; Assignment.    This Agreement, together with the Confidentiality Agreement and the Disclosure Schedule, constitute the entire agreement among the parties with respect to the subject matter hereof and supersede all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the subject matter hereof. This Agreement shall not be assigned (whether pursuant to a merger, by operation of law or otherwise), except any of the Buyer Parties may assign this Agreement to any direct or indirect wholly owned subsidiary of Parent; provided, however, that no such assignment shall relieve the assigning party of its obligations hereunder if the assignee does not perform its obligations.

        Section 10.06    Remedies.    Except as otherwise provided in Section 10.07 or elsewhere in this Agreement, any and all remedies expressly conferred upon a party to this Agreement shall be cumulative with, and not exclusive of, any other remedy contained in this Agreement, at law or in equity and the exercise by a party to this Agreement of any one remedy shall not preclude the exercise by it of any other remedy. Each of the Company Parties agrees that to the extent it has incurred losses or damages in connection with this Agreement the maximum aggregate liability of the Buyer Parties and the Guarantors, for such losses or damages (including any amounts payable pursuant to Section 9.04) shall be limited to an amount equal to $1,500,000,000, and in no event shall the Company Parties seek to recover any money damages in excess of such amount from the Buyer Parties or the Guarantors. In no event shall the Company Parties seek to recover any damages in connection with, relating to or arising out of this Agreement from any person, including the Buyer Parties or the Guarantors or any former, current or future general or limited partners, employees, stockholders, managers, members, directors, officers, Affiliates, agents or Representatives of the Buyer Parties or the Guarantors, except as specifically provided herein or in the Guarantees.

        Section 10.07    Specific Performance.    The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement were not performed by any Company Party in accordance with the terms hereof and that, prior to the termination of this Agreement pursuant to Section 9.01, the Buyer Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement by the Company Parties and to enforce specifically the terms and provisions of this Agreement in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. The parties acknowledge that none of the Company Parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement or to enforce specifically the terms and provisions of this Agreement and that the Company Parties' sole and exclusive remedy with respect to any such breach shall be the remedy set forth in the Guarantees, subject to the limitations of Section 10.06; provided, however, the Company Parties shall be entitled to seek specific performance to prevent any breach by the Buyer Parties of Sections 7.03(b) and 7.10(c).

        Section 10.08    Parties in Interest.    This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement, other than the provisions of Article III and Section 7.06 (which are intended to be for the benefit of the persons covered thereby or the persons entitled to payment thereunder and may be enforced by such persons).

        Section 10.09    Governing Law; Forum.    This Agreement, the Mergers and the other transactions contemplated hereby and all disputes, claims or controversies arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby shall be governed by and construed in accordance with the internal Laws of the State of Maryland without giving effect to any choice or conflict of law provision or rule (whether of

A-70



the State of Maryland or any other jurisdiction) that would cause the application of Laws of any jurisdictions other than those of the State of Maryland.

        Each of the parties hereto hereby irrevocably and unconditionally consents to submit to the sole and exclusive jurisdiction of the Courts of State of Maryland (the "Maryland Courts") for any litigation arising out of or relating to this Agreement, or the negotiation, validity or performance of this Agreement, or the transactions contemplated hereby (and agrees not to commence any litigation relating thereto except in such courts), waives any objection to the laying of venue of any such litigation in the Maryland Courts and agrees not to plead or claim in any Maryland Court that such litigation brought therein has been brought in any inconvenient forum. Each of the parties hereto agrees, (a) to the extent such party is not otherwise subject to service of process in the State of Maryland, to appoint and maintain an agent in the State of Maryland as such party's agent for acceptance of legal process, and (b) that service of process may also be made on such party by prepaid certified mail to the address for notice in Section 10.02 with a proof of mailing receipt validated by the United States Postal Service constituting evidence of valid service. Service made pursuant to (a) or (b) above shall have the same legal force and effect as if served upon such party personally within the State of Maryland.

        Section 10.10    Headings.    The descriptive headings contained in this Agreement are included for convenience of reference only and shall not affect in any way the meaning or interpretation of this Agreement.

        Section 10.11    Counterparts.    This Agreement may be executed and delivered (including by facsimile transmission) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.

        Section 10.12    Waiver.    Except as provided in this Agreement, no action taken pursuant to this Agreement, including any investigation by or on behalf of any party, shall be deemed to constitute a waiver by the party taking such action of compliance with any representations, warranties, covenants or agreements contained in this Agreement. The waiver by any party hereto of a breach of any provision hereunder shall not operate or be construed as a waiver of any prior or subsequent breach of the same or any other provision hereunder.

        Section 10.13    Waiver of Jury Trial.    Each of the parties hereto hereby waives to the fullest extent permitted by applicable Law any right it may have to a trial by jury with respect to any litigation directly or indirectly arising out of, under or in connection with this Agreement or the transactions contemplated by this Agreement. Each of the parties hereto (a) certifies that no representative, agent or attorney of any other party has represented, expressly or otherwise, that such other party would not, in the event of litigation, seek to enforce that foregoing waiver and (b) acknowledges that it and the other parties hereto have been induced to enter into this Agreement and the transactions contemplated by this Agreement, as applicable, by, among other things, the mutual waivers and certifications in this Section 10.13.

        No corporation, persons, transfer agent or other party shall be required to examine or investigate the terms or conditions contained in this Declaration of Trust or otherwise applicable to the Trust, and every such corporation, person, transfer agent or other party may deal with trust property and assets as if the Trustees were the sole and exclusive owners thereof free of all trusts; and no such corporation, person, transfer agent or other party dealing with the Trustees or with the Trust or Trust property and assets shall be required to see to the application of any money or property paid or delivered to any Trustee, or nominee, agent or representative of the Trust or the Trustees.

Any officer or agent elected or appointed by the Trustees may be removed by the Trustees whenever in its judgment the best interest of the Trust will be served thereby, but such removal shall be without prejudice to the contract rights, if any, of the person so removed. Election or appointment of any officer or agent shall not of itself create contract rights. The Trustees shall fix the compensation of all officers.


        Section 4.14
    Committees and Delegation of Powers and Duties.     

        The Trustees may, in their discretion, by resolution passed by a majority of the Trustees, designate from among the Trustees one or more committees which shall consist of one or more Trustees. The Trustees may designate one or more Trustees as alternate members of any such committee, who may replace any absent or disqualified member at any meeting of the committee. Such committees shall have and may exercise such powers as shall be conferred or authorized by the resolution appointing them (including, but not limited to, the determination of the type and amount of consideration at which Units are to be issued). A majority of any such committee may determine its action and fix the time and place of its meetings, unless the Trustees shall otherwise provide. The Trustees, by resolution

passed by a majority of the Trustees, may at any time change the membership of any committee, fill vacancies on it or dissolve it. The Bylaws, or a majority of the Trustees, may authorize any one or more of the Trustees, or any one or more of the officers or employees or agents of the Trust, on behalf of the Trust, to exercise and perform any and all powers granted to the Trustees, and to discharge any and all duties imposed on the Trustees, and to do any acts and to execute any instruments deemed by such person or persons to be necessary or appropriate to exercise such power or to discharge such duties, and to exercise his or her own judgment in so doing.

        Section 8.3
    Insurance.     

        Notwithstanding any other provisions of this Declaration of Trust, the Trust, for purposes of providing indemnification for its Trustees, officers, employees and agents, shall have the authority, without specific Unitholder approval, to enter into insurance or other arrangements, with persons or entities which are regularly engaged in the business of providing insurance coverage, to indemnify all Trustees, officers, employees and agents of the Trust against any and all liabilities and expenses incurred by them by reason of their being Trustees, officers, employees or agents of the Trust, whether or not the Trust would otherwise have the power under this Declaration of Trust or under Maryland law to indemnify such persons against such liability.

In the absence of fraud, the judgment of the Trustees as to the terms and conditions of insurance or other arrangement and the identity of the insurer or other arrangement shall not be subject to voidability, nor subject the Trustees approving such insurance or other arrangement to liability, on any ground, regardless of whether Trustees participating in and approving such insurance or other arrangement shall be beneficiaries thereof.

ANNEX A

        This Annex A, as amended from time to time, constitutes not only an integral part of the Declaration of Trust but also an agreement (this "Agreement") among all of the holders of Units (as defined herein) of the Trust, each of whom is identified on the books and records of the Trust. Each holder of Units at the Operating Trust Merger Effective Time (as defined herein) shall become a party to this agreement without further action required on the part of any such holder.

        The Trust has elected pursuant to Treasury Regulation § 301.7701-3(c) to be treated for federal income tax purposes as a "disregarded entity" not separate from its owner (and not as an "association taxable as a corporation"). Upon the issuance of units in connection with the SRW Merger (as defined in Exhibit D hereto), this election caused the Trust to become treated as a "partnership" for federal income tax purposes. The provisions in this Annex A relating to Capital Accounts (as defined herein) and allocations of Net Income and Net Loss (each as defined herein) (and items of income, gain, loss, and deduction) for federal income tax purposes are intended to be consistent with the provisions of the Code (as defined herein) and the Treasury Regulations promulgated under the Code applicable to entities that are characterized as "partnerships" for federal income tax purposes.

        Section 5.4

The Trustee shall be reimbursed on a monthly basis, or such other basis as the Trustee may determine in its sole and absolute discretion, for all expenses it incurs relating to the ownership and operation of, or for the benefit of, the Trust (including, without limitation, expenses related to or resulting from the operations of the Trustee and to the management and administration of any Subsidiaries of the Trustee or the Trust or Affiliates of the Trust, such as auditing expenses and filing fees); provided that the amount of any such reimbursement shall be reduced by (x) any interest earned by the Trustee with respect to bank accounts or other instruments or accounts held by it on behalf of the Trust as permitted in Section 5.5 (which interest is considered to belong to the Trust and shall be paid over to the Trust to the extent not applied to reimburse the Trustee for expenses hereunder); and (y) any amount derived by the Trustee from any investments permitted in Section 5.5. The Trustee shall determine in good faith the amount of expenses incurred by it related to the ownership of Trust Interests and operation of, or for the benefit of, the Trust. If certain expenses are incurred that are related both to the ownership of Trust Interests or operation of, or for the benefit of, the Trust and to the ownership of other assets (other than Qualified REIT Subsidiaries or limited liability companies as permitted under Section 5.7.A) or the operation of other businesses, such expenses will be allocated to the Trust and such other entities (including the Trustee) owning such other assets or businesses in such a manner as the Trustee in its sole and absolute discretion deems fair and reasonable. Such reimbursements shall be in addition to any reimbursement to the Trustee pursuant to Section 8.3.C and as a result of indemnification pursuant to Section 5.7.

        D.
    Reimbursement Not a Distribution.     If and to the extent any reimbursement made pursuant to this Section 5.4 is determined for federal income tax purposes not to constitute a payment of expenses of the Trust, the amount so determined shall constitute a guaranteed payment with respect to capital within the meaning of Section 707(c) of the Code, shall be treated consistently therewith by the Trust and all Unitholders and shall not be treated as a distribution for purposes of computing the Unitholders' Capital Accounts.


        Section 5.5
    Outside Activities of the Trustee.     

        The Trustee and any officer, director, employee, agent, trustee, Affiliate or shareholder of the Trustee shall be entitled to and may have business interests and engage in business activities in addition to those relating to the Trust, including business interests and activities that are in direct competition with the Trust or that are enhanced by the activities of the Trust. Neither the Trust nor any Unitholders

B-33



or any other Person shall have any rights by virtue of this Agreement in any business ventures of the Trustee, and the Trustee shall have no obligation pursuant to this Agreement to offer any interest in any such business ventures to the Trust, any Unitholder or any other Person, even if such opportunity is of a character which, if presented to the Trust, any Unitholder or any other Person, could be taken by the Trust, any Unitholder or such Person.

        Unless otherwise required by the Declaration of Trust, this Agreement or law, the Trustee shall be permitted to hold such bank accounts or similar instruments or accounts in its name as it deems necessary to carry out its responsibilities and purposes as contemplated under this Agreement and its organizational documents (provided that accounts held on behalf of the Trust to permit the Trustee to carry out its responsibilities under this Agreement shall be considered to belong to the Trust and the interest earned thereon shall, subject to Section 5.4.B, be applied for the benefit of the Trust). The Trustee shall be permitted to acquire, directly or through one or more Qualified REIT Subsidiaries or limited liability companies, Qualified Assets. The Trustee and any of its Affiliates may acquire Trust Interests and shall be entitled to exercise all rights of a Unitholder relating to such Trust Interests.

    Transactions with Certain Affiliates.     

        The Trust may, directly or indirectly, sell, transfer or convey any property to, or purchase any property from, or borrow funds from, or lend funds to, any Unitholder or any affiliate of the Trust or the Trustee, subject to Maryland law.


        Section 5.7
    Indemnification.     


        A.
    General.     The Trust shall indemnify each Indemnitee to the fullest extent provided by the Act from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorneys fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from or in connection with any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, incurred by the Indemnitee and relating to the Trust or the Trustee or the operation of, or the ownership of property by, the Trust or the Trustee as set forth in this Agreement in which any such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, unless it is established by a final determination of a court of competent jurisdiction that: (i) the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty, (ii) the Indemnitee actually received an improper personal benefit in money, property or services, or (iii) in the case of any criminal proceeding, the Indemnitee had reasonable cause to believe that the act or omission was unlawful. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Indemnitee did not meet the requisite standard of conduct set forth in this Section 5.7.A. The termination of any proceeding by conviction or upon a plea of nolo contendere or its equivalent, or an entry of an order of probation prior to judgment, creates a rebuttable presumption that the Indemnitee acted in a manner contrary to that specified in this Section 5.7.A with respect to the subject matter of such proceeding. Any indemnification pursuant to this Section 5.7 shall be made only out of the assets of the Trust, and any insurance proceeds from the liability policy covering the Trustee and any Indemnitee, and neither the Trustee nor any other Unitholder shall have any obligation to contribute to the capital of the Trust or otherwise provide funds to enable the Trust to fund its obligations under this Section 5.7.


        B.
    Advancement of Expenses.     Reasonable expenses expected to be incurred by an Indemnitee may be paid or reimbursed by the Trust in advance of the final disposition of any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative made or threatened against an Indemnitee upon receipt by the Trust of (i) a written affirmation by the Indemnitee of the Indemnitee's good faith belief that the standard of conduct necessary for indemnification by the Trust as authorized in Section 5.7.A has been met and (ii) a written undertaking

B-34


by or on behalf of the Indemnitee to repay the amount if it shall ultimately be determined that the standard of conduct has not been met.


        C.
    No Limitation of Rights.     The indemnification provided by this Section 5.7 shall be in addition to any other rights to which an Indemnitee or any other Person may be entitled under any agreement, pursuant to any vote of the Unitholders, as a matter of law or otherwise, and shall continue as to an Indemnitee who has ceased to serve in such capacity unless otherwise provided in a written agreement pursuant to which such Indemnitee is indemnified.


        D.
    Insurance.     The Trust may purchase and maintain insurance on behalf of the Indemnitees and such other Persons as the Trustee shall determine against any liability that may be asserted against or expenses that may be incurred by such Person in connection with the Trust's activities, regardless of whether the Trust would have the power to indemnify such Person against such liability under the provisions of this Agreement.


        E.
    Benefit Plan Fiduciary.     For purposes of this Section 5.7, (i) excise taxes assessed on an Indemnitee, or for which the Indemnitee is otherwise found liable, with respect to a Plan pursuant to applicable law shall constitute fines within the meaning of this Section 5.7, and (ii) actions taken or omitted by the Indemnitee with respect to a Plan in the performance of its duties for a purpose reasonably believed by it to be in the interest of the participants and beneficiaries of such Plan shall be deemed to be for a purpose which is not opposed to the best interests of the Trust.


        F.
    No Personal Liability for Unitholders.     In no event may an Indemnitee subject any of the Unitholders to personal liability by reason of the indemnification provisions set forth in this Agreement.


        G.
    Interested Transactions.     An Indemnitee shall not be denied indemnification in whole or in part under this Section 5.7 because the Indemnitee had an interest in the transaction with respect to which the indemnification applies if the transaction was otherwise permitted by the terms of this Agreement.


        H.
    Benefit.     The provisions of this Section 5.7 are for the benefit of the Indemnitees, their heirs, successors, assigns and administrators and shall not be deemed to create any rights for the benefit of any other Persons. Any amendment, modification or repeal of this Section 5.7, or any provision hereof, shall be prospective only and shall not in any way affect the limitation on the Trust's liability to any Indemnitee under this Section 5.7 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or related to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.


        I.
    Indemnification Payments Not Distribution.     If and to the extent any payments to the Trustee pursuant to this Section 5.7 constitute gross income to the Trustee (as opposed to the repayment of advances made on behalf of the Trust), such amounts shall constitute guaranteed payments within the meaning of Section 707(c) of the Code, shall be treated consistently therewith by the Trust and all Unitholders, and shall not be treated as distributions for purposes of computing the Unitholders' Capital Accounts.


        J.
    Exception to Indemnification.     Notwithstanding anything to the contrary in this Agreement, the Trustee shall not be entitled to indemnification hereunder for any loss, claim, damage, liability or expense for which the Trustee is obligated to indemnify the Trust under any other agreement between the Trustee and the Trust.


        Section 5.8
    Liability of the Trustee.     


        A.
    General.     To the maximum extent that Maryland law in effect from time to time permits limitation of the liability of trustees of a real estate investment trust, the Trustee shall not be liable to the Trust or to any Unitholder for money damages. Neither the amendment nor repeal of this

B-35


Section 5.8.A, nor the adoption or amendment of any other provision of the Declaration of Trust inconsistent with this Section 5.8.A, shall apply to or affect in any respect the applicability of the preceding sentence with respect to any act or failure to act which occurred prior to such amendment, repeal or adoption. In the absence of any Maryland statute limiting the liability of trustees of a Maryland real estate investment trust for money damages in a suit by or on behalf of the Trust or by any Unitholder, the Trustee shall not be liable to the Trust or to any Unitholder for money damages except to the extent that (i) the Trustee actually received an improper benefit or profit in money, property or services, for the amount of the benefit or profit in money, property or services actually received; or (ii) a judgment or other final adjudication adverse to the Trustee is entered in a proceeding based on a finding in the proceeding that the Trustee's action or failure to act was the result of active and deliberate dishonesty and was material to the cause of action adjudicated in the proceeding.


        B.
    No Obligation to Consider Separate Interests of other Unitholders.     The Unitholders (including the Trustee to the extent that its Trust Interest is not in its capacity as Trustee) expressly acknowledge that the Trustee is acting on behalf of the Trust and the Trustee's shareholders collectively, that the Trustee is under no obligation to consider the separate interests of the other Unitholders (including, without limitation, the tax consequences to the other Unitholders) in deciding whether to cause the Trust to take (or decline to take) any actions, and that the Trustee shall not be liable for monetary damages for losses sustained, liabilities incurred or benefits not derived by Unitholders in connection with such decisions except as set forth in Exhibit D and/or Exhibit F, unless the Trustee acted in bad faith and the act or omission was material to the matter giving rise to the loss, liability or benefit not derived.


        C.
    Actions of Agents.     Subject to its obligations and duties as Trustee set forth in Section 5.1.A, the Trustee may exercise any of the powers granted to it by this Agreement and perform any of the duties imposed upon it hereunder either directly or by or through its agents. The Trustee shall not be responsible for any misconduct or negligence on the part of any such agent appointed by the Trustee in good faith.


        D.
    Effects of Amendment.     Notwithstanding any other provision contained herein, any amendment, modification or repeal of this Section 5.8 or any provision hereof shall be prospective only and shall not in any way affect the limitations on the Trustee's liability to the Trust and the other Unitholders under this Section 5.8 as in effect immediately prior to such amendment, modification or repeal with respect to claims arising from or relating to matters occurring, in whole or in part, prior to such amendment, modification or repeal, regardless of when such claims may arise or be asserted.


        Section 5.9

In no event shall any Person dealing with the Trustee or its representatives be obligated to ascertain that the terms of this Agreement have been complied with or to inquire into the necessity or expedience of any act or action of the Trustee or its representatives. Each and every certificate, document or other instrument executed on behalf of the Trust by the Trustee or its representatives shall be conclusive evidence in favor of any and every Person relying thereon or claiming thereunder that (i) at the time of the execution and delivery of such certificate, document or instrument, this Agreement was in full force and effect, (ii) the Person executing and delivering such certificate, document or instrument was duly authorized and empowered to do so for and on behalf of the Trust and (iii) such certificate, document or instrument was duly executed and delivered in accordance with the terms and provisions of this Agreement and is binding upon the Trust.

        Except as otherwise provided herein, the Trustee shall, in its sole and absolute discretion, determine whether to make any available election pursuant to the Code; provided, however, that the Trustee shall make the election under Section 754 of the Code in accordance with applicable regulations thereunder and the Trustee shall have the right to seek to revoke any such election (including, without limitation, the election under Section 754 of the Code) upon the Trustee's determination in its sole and absolute discretion that such revocation is in the best interests of the Unitholders; provided, however, that the Trust shall not affirmatively revoke its election to be treated as

B-39



a "partnership" for federal income tax prior to January 1, 2044 except as permitted under Section 5.3.C.


        Section 8.3
    Tax Matters Partner.     


        A.
    General.     The Trustee shall be the "tax matters partner" of the Trust for federal income tax purposes. Pursuant to Section 6230(e) of the Code, upon receipt of notice from the IRS of the beginning of an administrative proceeding with respect to the Trust, the tax matters partner shall furnish the IRS with the name, address, taxpayer identification number, and profit interest of each of the Unitholders; provided, however, that such information is provided to the Trust by the Unitholders.


        B.
    Powers.     The tax matters partner is authorized, but not required:

        The taking of any action and the incurring of any expense by the tax matters partner in connection with any such proceeding, except to the extent required by law, is a matter in the sole and absolute discretion of the tax matters partner and the provisions relating to indemnification of the Trustee set forth in Section 5.7 of this Agreement shall be fully applicable to the tax matters partner in its capacity as such.

        Section 8.5
    Withholding.     

        Each Unitholder hereby authorizes the Trust to withhold from or pay on behalf of or with respect to such Unitholder any amount of federal, state, local, or foreign taxes that the Trustee determines that the Trust is required to withhold or pay with respect to any amount distributable or allocable to such Unitholder pursuant to this Agreement, including, without limitation, any taxes required to be withheld or paid by the Trust pursuant to Section 1441, 1442, 1445 or 1446 of the Code. Any amount paid on behalf of or with respect to a Unitholder shall constitute a loan by the Trust to such Unitholder, which loan shall be repaid by such Unitholder within fifteen (15) days after notice from the Trustee that such payment must be made unless (i) the Trust withholds such payment from a distribution which would otherwise be made to the Unitholder or (ii) the Trustee determines, in its sole and absolute discretion, that such payment may be satisfied out of the available funds of the Trust which would, but for such payment, be distributed to the Unitholder. Any amounts withheld pursuant to the foregoing clause (i) or (ii) shall be treated as having been distributed to such Unitholder. Each Unitholder hereby unconditionally and irrevocably grants to the Trust a security interest in such Unitholder's Trust Interest to secure such Unitholder's obligation to pay to the Trust any amounts required to be paid pursuant to this Section 8.5. In the event that a Unitholder fails to pay any amounts owed to the Trust pursuant to this Section 8.5 when due, the Trustee may, in its sole and absolute discretion, elect to make the payment to the Trust on behalf of such defaulting Unitholder, and in such event shall be deemed to have loaned such amount to such defaulting Unitholder and shall succeed to all rights and remedies of the Trust as against such defaulting Unitholder. Without limitation, in such event the Trustee shall have the right to receive distributions that would otherwise be distributable to such defaulting Unitholder until such time as such loan, together with all interest thereon, has been paid in full, and any such distributions so received by the Trustee shall be treated as having been distributed to the defaulting Unitholder and immediately paid by the defaulting Unitholder to the Trustee in repayment of such loan. Any amounts payable by a Unitholder hereunder shall bear interest at the lesser of (A) the base rate on corporate loans at large United States money center commercial banks, as published from time to time in the Wall Street Journal, plus four (4) percentage points, or (B) the maximum lawful rate of interest on such obligation, such interest to accrue from the date such amount is due (i.e., fifteen (15) days after demand) until such amount is paid in full. Each Unitholder shall take such actions as the Trust or the Trustee shall request in order to perfect or enforce the security interest created hereunder.


ARTICLE 9.
TRANSFERS AND WITHDRAWALS


        Section 9.1
    Transfer.     

        The term "transfer," when used in this Article 9 with respect to a Trust Interest or Unit, shall be deemed to refer to a transaction by which the Trustee purports to assign all or any part of its Trust Interest to another Person or by which a Unitholder purports to assign all or any part of its Trust Interest to another Person, and includes a sale, assignment, gift, pledge, encumbrance, hypothecation, mortgage, exchange or any other disposition by law or otherwise. The term "transfer" when used in this Article 9 does not include any redemption of Units by a Unitholder or acquisition of Units from a Unitholder by the Trustee. No part of the interest of a Unitholder shall be subject to the claims of any creditor, any spouse for alimony or support, or to legal process, and may not be voluntarily or involuntarily alienated or encumbered except as may be specifically provided for in this Agreement or as required by law.


        Section 9.2
    Transfer of Trustee's Trust Interest.     The Trustee may transfer and assign any of its Trust Interest and shall be entitled to withdraw as the Trustee without the consent of any Unitholder.

B-41



        Section 9.3
    Unitholders' Rights to Transfer.     


        A.
    General.     Units in the Trust shall be transferable only in accordance with this Section 9.3 and the provisions of their respective terms as set forth in Exhibits D, E, F and G to Annex A hereto and Section 5.2 of the Declaration of Trust.


        B.
    Incapacitated Unitholders.     If a Unitholder is subject to Incapacity, the executor, administrator, trustee, committee, guardian, conservator or receiver of such Unitholder's estate shall have all the rights of a Unitholder, but not more rights than those enjoyed by other Unitholders, for the purpose of settling or managing the estate and such power as the Incapacitated Unitholder possessed to transfer all or any part of its interest in the Trust. The Incapacity of a Unitholder, in and of itself, shall not dissolve or terminate the Trust.


        C.
    Restrictions on Transfer.     With respect to Series P Preferred Units and Series Q Preferred Units, a Unitholder may not transfer all or any portion of its Trust Interest, or any of such Unitholder's rights as a Unitholder, without the prior written consent of the Trustee, which consent may be withheld in the Trustee's sole and absolute discretion. Any transfer otherwise permitted under Section 9.3.B and this Section 9.3.C shall be subject to the conditions set forth in Sections 9.3.D, 9.3.E and 9.3.F, and all permitted transfers shall be subject to Section 9.4. A Unitholder may transfer, with or without the consent of the Trustee, all or a portion of its Trust Interest (i) in the case of a Unitholder who is an individual, to a member of his Immediate Family, any trust formed for the benefit of himself and/or members of his Immediate Family, or any partnership, limited liability company, joint venture, corporation or other business entity comprised only of himself and/or members of his Immediate Family and entities the ownership interests in which are owned by or for the benefit of himself and/or members of his Immediate Family, (ii) in the case of a Unitholder which is a trust, to the beneficiaries of such trust, (iii) in the case of a Unitholder which is a partnership, limited liability company, joint venture, corporation or other business entity to which Units were transferred pursuant to clause (i) above, to its partners, owners or stockholders, as the case may be, who are members of the Immediate Family of or are actually the Person(s) who transferred Units to it pursuant to clause (i) above, (iv) in the case of a Unitholder which acquired Units as of the date hereof and which is a partnership, limited liability company, joint venture, corporation or other business entity, to its partners, owners, stockholders or Affiliates thereof, as the case may be, or the Persons owning the beneficial interests in any of its partners, owners or stockholders or Affiliates thereof (it being understood that this clause (iv) will apply to all of each Person's Trust Interests whether the Units relating thereto were acquired on the date hereof or hereafter), (v) in the case of a Unitholder which is a partnership, limited liability company, joint venture, corporation or other business entity other than any of the foregoing described in clause (iii) or (iv), in accordance with the terms of any agreement between such Unitholder and the Trust pursuant to which such Trust Interest was issued, (vi) pursuant to a gift or other transfer without consideration, (vii) pursuant to applicable laws of descent or distribution, (viii) to another Unitholder and (ix) pursuant to a grant of security interest or other encumbrance effectuated in a bona fide transaction or as a result of the exercise of remedies related thereto, subject to the provisions of Section 9.3.F hereof. A trust or other entity will be considered formed "for the benefit" of a Unitholder's Immediate Family even though some other Person has a remainder interest under or with respect to such trust or other entity.


        D.
    No Transfers Violating Securities Laws.     The Trustee may prohibit any transfer of Units by a Unitholder unless it receives a written opinion of legal counsel (which opinion and counsel shall be reasonably satisfactory to the Trust) to such Unitholder to the effect that such transfer would not require filing of a registration statement under the Securities Act or would not otherwise violate any federal or state securities laws or regulations applicable to the Trust or the transfer of such Units or, at the option of the Trust, an opinion of legal counsel to the Trust to the same effect.

B-42



        E.
    No Transfers Affecting Tax Status of Trust.     No transfer of Units by a Unitholder may be made to any Person if (i) in the opinion of legal counsel for the Trust, it would result in the Trust being treated as an association taxable as a corporation for federal income tax purposes (except pursuant to a transaction expressly permitted under Section 5.1 or Section 9.2), (ii) in the opinion of legal counsel for the Trust, it could reasonably be expected to cause the Trustee or any Trustee Related Party that is a REIT to no longer qualify as a REIT or would subject the Trustee or any such Trustee Related Party to any additional taxes under Section 857 or Section 4981 of the Code or (iii) such transfer is effectuated through an "established securities market" or a "secondary market (or the substantial equivalent thereof)" within the meaning of Section 7704 of the Code.


        F.
    No Transfers to Holders of Nonrecourse Liabilities.     No pledge or transfer of any Units may be made to a lender to the Trust or any Person who is related (within the meaning of Section 1.752-4(b) of the Regulations) to any lender to the Trust whose loan constitutes a Nonrecourse Liability unless the Trustee is provided notice thereof, and the lender enters into an arrangement with the Trust and the Trustee, in form and substance satisfactory to the Trustee, to take such action and comply with such conditions as the Trustee determines to be appropriate.


        Section 9.4
    General Provisions.     


        A.
    Timing of Transfers.     Transfers pursuant to this Article 9 may only be made on the first day of a fiscal quarter of the Trust, unless the Trustee otherwise agrees.


        B.
    Allocations.     If any Trust Interest is transferred or assigned in compliance with the provisions of this Article 9, on any day other than the first day of a Fiscal Year, then Net Income, Net Losses, each item thereof and all other items attributable to such interest for such Fiscal Year shall be divided and allocated between the transferor Unitholder and the transferee Unitholder by taking into account their varying interests during the Fiscal Year in accordance with Section 706(d) of the Code, using the interim closing of the books method (unless the Trustee, in its sole and absolute discretion, elects to adopt a daily, weekly or monthly proration method, in which event Net Income, Net Losses and each item thereof for such Fiscal Year shall be prorated based upon the applicable period selected by the Trustee). Solely for purposes of making such allocations, each of such items for the calendar month in which the transfer or assignment occurs shall be allocated to the transferee Unitholder. All distributions of Available Cash attributable to such Unit with respect to which the Trust Record Date is before the date of such transfer or assignment shall be made to the transferor Unitholder, as the case may be, and, in the case of a transfer or assignment, all distributions of Available Cash thereafter attributable to such Unit shall be made to the transferee Unitholder.


        C.
    Additional Restrictions.     In addition to any other restrictions on transfer herein contained, including without limitation the provisions of this Article 9 and Article 5, in no event may any transfer or assignment of a Trust Interest by any Unitholder be made without the express consent of the Trustee, in its sole and absolute discretion, (i) to any person or entity who lacks the legal right, power or capacity to own a Trust Interest; (ii) in violation of applicable law; (iii) of any component portion of a Trust Interest, such as the Capital Account, or rights to distributions, separate and apart from all other components of a Trust Interest; (iv) if in the opinion of legal counsel to the Trust such transfer would cause a termination of the Trust for federal or state income tax purposes (except pursuant to a transaction expressly permitted under Section 5.1 or Section 9.2); (v) if such transfer would, in the opinion of counsel to the Trust, cause any portion of the assets of the Trust to constitute assets of any ERISA Plan Investor pursuant to 29 C.F.R. § 2510.3-101, or any successor regulation thereto; (vi) if such transfer subjects the Trust or the activities of the Trust to regulation under the Investment Company Act of 1940, the Investment Advisors Act of 1940 or ERISA, each as amended; or (vii) if such transfer could reasonably be expected to cause the Trustee or any Trustee Related Party that is a REIT to fail to remain qualified as a REIT so long as the Trustee and/or such Trustee Related Party, as the case may be, have determined to continue to qualify as a REIT.

B-43



        D.
    Avoidance of "Publicly Traded Partnership" Status.     The Trustee shall monitor the transfers of interests in the Trust to determine (i) if such interests are being traded on an "established securities market" or a "secondary market (or the substantial equivalent thereof)" within the meaning of Section 7704 of the Code and (ii) whether additional transfers of interests would result in the Trust being unable to qualify for at least one of the "safe harbors" set forth in Regulations Section 1.7704-1 (or such other guidance subsequently published by the IRS setting forth safe harbors under which interests will not be treated as "readily tradable on a secondary market (or the substantial equivalent thereof)" within the meaning of Section 7704 of the Code) (the "Safe Harbors"). The Trustee shall take all steps reasonably necessary or appropriate to prevent any trading of interests or any recognition by the Trust of transfers made on such markets and, except as otherwise provided herein, to insure that at least one of the Safe Harbors is met; provided, however, that the foregoing shall not authorize the Trustee to limit or restrict in any manner the right of any holder of Series O Preferred Units to exercise the redemption rights in accordance with the terms of Exhibit F unless, and only to the extent that, outside tax counsel provides to the Trustee an opinion to the effect that, in the absence of such limitation or restriction, there is a significant risk that the Trust will be treated as a "publicly traded partnership" and, by reason thereof, will be taxable as a corporation.


ARTICLE 10.
ADDITIONAL UNITHOLDERS


        A.
    General.     A Person who makes a Capital Contribution to the Trust in accordance with this Agreement shall become a Unitholder only with the consent of the Trustee and only upon furnishing to the Trustee (i) evidence of acceptance in form satisfactory to the Trustee of all of the terms and conditions of this Agreement, and (ii) such other documents or instruments as may be required in the discretion of the Trustee for such Person to become a Unitholder. Any such Person shall become a Unitholder effective on the date upon which the name of such Person is recorded on the books and records of the Trust, following the consent of the Trustee.


        B.
    Allocations to Additional Unitholders.     If any Person becomes a Unitholder on any day other than the first day of a Fiscal Year, then Net Income, Net Losses, each item thereof and all other items allocable among Unitholders for such Fiscal Year shall be allocated among such Unitholder and all other Unitholders by taking into account their varying interests during the Fiscal Year in accordance with Section 706(d) of the Code, using the interim closing of the books method (unless the Trustee, in its sole and absolute discretion, elects to adopt a daily, weekly or monthly proration method, in which event Net Income, Net Losses, and each item thereof would be prorated based upon the applicable period selected by the Trustee). Solely for purposes of making such allocations, each of such items for the calendar month in which a Person becomes a Unitholder shall be allocated among all the Unitholders, including such new Unitholder. All distributions of Available Cash with respect to which the Trust Record Date is before the date of such admission shall be made solely to Unitholders other than the new Unitholder, and all distributions of Available Cash thereafter shall be made to all the Unitholders, including such new Unitholder.


ARTICLE 11.
DISSOLUTION, LIQUIDATION AND TERMINATION


        Section 11.1
    Dissolution.     

        The Trust shall dissolve, and its affairs shall be wound up, upon the first to occur of any of the following ("Liquidating Events"):

B-44



        Section 11.2
    Winding Up.     


        A.
    General.     Upon the occurrence of a Liquidating Event, the Trust shall continue solely for the purposes of winding up its affairs in an orderly manner, liquidating its assets, and satisfying the claims of its creditors and Unitholders. No Unitholder shall take any action that is inconsistent with, or not necessary to or appropriate for, the winding up of the Trust's business and affairs. The Trustee (or, if there is no remaining Trustee, any Person elected by a majority in interest of the Unitholders (the "Liquidator")) shall be responsible for overseeing the winding up and dissolution of the Trust and shall take full account of the Trust's liabilities and property and the Trust property shall be liquidated as promptly as is consistent with obtaining the fair value thereof, and the proceeds therefrom (which may, to the extent determined by the Trustee, include equity or other securities of the Trustee or any other entity) shall be applied and distributed in the following order:

        The Trustee shall not receive any additional compensation for any services performed pursuant to this Article 11.


        B.
    Deferred Liquidation.     Notwithstanding the provisions of Section 11.2.A which require liquidation of the assets of the Trust, but subject to the order of priorities set forth therein, if prior to or upon dissolution of the Trust the Liquidator determines that an immediate sale of part or all of the

B-45


Trust's assets would be impractical or would cause undue loss to the Unitholders, the Liquidator may, in its sole and absolute discretion, defer for a reasonable time the liquidation of any assets except those necessary to satisfy liabilities of the Trust (including to those Unitholders as creditors) or distribute to the Unitholders, in lieu of cash, as tenants in common and in accordance with the provisions of Section 11.2.A, undivided interests in such Trust assets as the Liquidator deems not suitable for liquidation. Any such distributions in kind shall be made only if, in the good faith judgment of the Liquidator, such distributions in kind are in the best interest of the Unitholders, and shall be subject to such conditions relating to the disposition and management of such properties as the Liquidator deems reasonable and equitable and to any agreements governing the operation of such properties at such time. The Liquidator shall determine the fair market value of any property distributed in kind using such reasonable method of valuation as it may adopt.


        Section 11.3
    Compliance with Timing Requirements of Regulations; Restoration of Deficit Capital Accounts.     


        A.
    Timing of Distributions.     If the Trust is "liquidated" within the meaning of Regulations Section 1.704-1(b)(2)(ii)(g), distributions shall be made under this Article 11 to the Trustee and Unitholders who have positive Capital Accounts in compliance with Regulations Section 1.704-1(b)(2)(ii) (b)(2). In the discretion of the Trustee, a pro rata portion of the distributions that would otherwise be made to the Trustee and Unitholders pursuant to this Article 11 may be: (A) distributed to a trust established for the benefit of the Trustee and Unitholders for the purposes of liquidating Trust assets, collecting amounts owed to the Trust and paying any contingent or unforeseen liabilities or obligations of the Trust or of the Trustee arising out of or in connection with the Trust (in which case the assets of any such trust shall be distributed to the Trustee and Unitholders from time to time, in the reasonable discretion of the Trustee, in the same proportions as the amount distributed to such trust by the Trust would otherwise have been distributed to the Trustee and Unitholders pursuant to this Agreement); or (B) withheld to provide a reasonable reserve for Trust liabilities (contingent or otherwise) and to reflect the unrealized portion of any installment obligations owed to the Trust; provided that such withheld amounts shall be distributed to the Trustee and Unitholders as soon as practicable.


        B.
    Restoration of Deficit Capital Accounts Upon Liquidation of the Trust.     If any Unitholder has a deficit balance in its Capital Account (after giving effect to all contributions, distributions and allocations for all taxable years, including the year during which such liquidation occurs), such Unitholder shall have no obligation to make any contribution to the capital of the Trust with respect to such deficit, and such deficit shall not be considered a debt owed to the Trust or to any other Person for any purpose whatsoever, except as otherwise set forth in this Section 11.3.B, or as otherwise expressly agreed in writing by the affected Unitholder and the Trust after the date hereof. Notwithstanding the foregoing, (i) if the Trustee has a deficit balance in its Capital Account (after giving effect to all contributions, distributions, and allocations for all Fiscal Years or portions thereof, including the year during which such liquidation occurs), the Trustee shall contribute to the capital of the Trust the amount necessary to restore such deficit balance to zero in compliance with Regulations Section 1.704-1(b)(2)(ii)(b)(3); and (ii) the first sentence of this Section 11.3.B shall not apply with respect to any other Unitholder to the extent, but only to such extent, that such Unitholder previously has agreed in writing, with the consent of the Trustee, to undertake an express obligation to restore all or any portion of a deficit that may exist in its Capital Account upon a liquidation of the Trust. Any contribution required of a Unitholder under this Section 11.3.B shall be made on or before the later of (i) the end of the Fiscal Year in which the interest is liquidated or (ii) the ninetieth (90th) day following the date of such liquidation.

B-46



        Section 11.4
    Rights of Unitholders.     

        Except as otherwise provided in this Agreement, each Unitholder shall look solely to the assets of the Trust for the return of its Capital Contributions and shall have no right or power to demand or receive property other than cash from the Trust. Except as otherwise expressly provided in this Agreement, no Unitholder shall have priority over any other Unitholder as to the return of its Capital Contributions, distributions, or allocations.


        Section 11.5
    Notice of Dissolution.     

        If a Liquidating Event occurs or an event occurs that would, but for provisions of an election or objection by one or more Unitholders pursuant to Section 11.1, result in a dissolution of the Trust, the Trustee shall, within thirty (30) days thereafter, provide written notice thereof to each of the Unitholders.


        Section 11.6
    Reasonable Time for Winding-Up.     

        A reasonable time shall be allowed for the orderly winding-up of the business and affairs of the Trust and the liquidation of its assets pursuant to Section 11.2 hereof, in order to minimize any losses otherwise attendant upon such winding-up, and the provisions of this Agreement shall remain in effect among the Unitholders during the period of liquidation.


        Section 11.7
    Waiver of Partition.     

        Each Unitholder hereby waives any right to partition of the Trust property.


        Section 11.8
    Liability of the Liquidator.     

        The Liquidator shall be indemnified and held harmless by the Trust in the same manner and to the same degree as an Indemnitee may be indemnified pursuant to Section 5.7.


ARTICLE 12.
AMENDMENT OF AGREEMENT


        Section 12.1
    General.     

        Except as provided in Section 12.2 or 12.3, a proposed amendment shall be adopted and be effective as an amendment hereto if it is approved by the Trustee and it receives the approval of Unitholders holding a majority of the Units then outstanding and entitled to vote thereon.


        Section 12.2
    Amendments Requiring Approval of Class A-2 Unitholders.     

        Notwithstanding Section 12.1, this Agreement may be amended, after the Trustee has declared such amendment advisable, by the holders of at least a majority of the Class A-2 Units then outstanding and entitled to vote thereon, as may be required to facilitate or implement any of the following purposes:

B-47


        The Trustee shall notify the Unitholders when any action under this Section 12.2 is taken in the next regular communication to the Unitholders; provided, however, that no notice need be given of any amendment of this Agreement to reflect any change in the status of Unitholders in accordance with this Agreement that does not alter the contract rights of the Unitholder's Units. For purposes of the immediately preceding sentence, notwithstanding any other means by which the Trustee may provide any such notice to the Unitholders, such notice requirement shall be deemed to have been satisfied upon the filing with the Securities and Exchange Commission by the Trust or the Trustee of any amendment to this Agreement permitted under this Section 12.2(B) as an exhibit to (i) a registration statement filed by the Trust or the Trustee under the Securities Act or (ii) any report or other document filed by the Trust or the Trustee under the Exchange Act.


        Section 12.3
    Other Amendments Requiring Certain Unitholder Approval.     

        Notwithstanding anything in this Article 12 to the contrary, this Agreement shall not be amended with respect to any Unitholder adversely affected thereby without the approval of such Unitholder, if such amendment would (i) convert a Unitholder's interest in the Trust into a trustee's interest, (ii) modify the limited liability of a Unitholder or require the Unitholder to make additional Capital Contributions, (iii) amend Section 5.3.A, (iv) amend Article 3 or 4 (except as permitted pursuant to Sections 2.2, 3.1.B and 12.2(C)), (v) amend Sections 9.3 or 9.4, or add any additional restrictions to those provided in Section 9.6.E, (vi) amend Section 11.1(i)-(iii) to cause a termination of the Trust prior to the time set forth therein or amend Section 5.3.C to permit a termination of the Trust's status as a "partnership" for federal income tax purposes prior to the time set forth therein (as to which matters only original holders of Series O Preferred Units who are "Original Smith Limited Partners" (as defined in Section 11.1(i)) have a right of approval), (vii) amend this Section 12.3, or (viii) amend Section 13.1. This Section 12.3 does not require unanimous approval of all Unitholders adversely affected unless the amendment is to be effective against all Unitholders adversely affected.

EXHIBIT A

CAPITAL ACCOUNT MAINTENANCE


        Section 1.
    Capital Accounts of the Unitholders.     

        A.    The Trust shall maintain for each Unitholder a separate Capital Account in accordance with the rules of Regulations Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions and any other deemed contributions made by such Unitholder to the Trust pursuant to this Agreement and (ii) all items of Trust income and gain (including income and gain exempt from tax) computed in accordance with Section 1.B hereof and allocated to such Unitholder pursuant to Section 4.1.A of the Agreement and Exhibit B thereof, and decreased by (x) the amount of cash or Agreed Value of all actual and deemed distributions of cash or property made to such Unitholder pursuant to this Agreement and (y) all items of Trust deduction and loss computed in accordance with Section 1.B hereof and allocated to such Unitholder pursuant to Section 4.1.B of the Agreement and Exhibit B hereof.

        B.    For purposes of computing the amount of any item of income, gain, deduction or loss to be reflected in the Unitholders' Capital Accounts, unless otherwise specified in this Agreement, the determination, recognition and classification of any such item shall be the same as its determination, recognition and classification for federal income tax purposes determined in accordance with Section 703(a) of the Code (for this purpose all items of income, gain, loss or deduction required to be stated separately pursuant to Section 703(a)(1) of the Code shall be included in taxable income or loss), with the following adjustments:

B-50


        C.    A transferee of a Unit shall succeed to a pro rata portion of the Capital Account of the transferor.

        D.    (1) Consistent with the provisions of Regulations Section 1.704-1(b)(2)(iv)(f), and as provided in Section 1.D, the Carrying Values of all Trust assets shall be adjusted upward or downward to reflect any Unrealized Gain or Unrealized Loss attributable to such Trust property, as of the times of the adjustments provided in Section 1.D (2) hereof, as if such Unrealized Gain or Unrealized Loss had been recognized on an actual sale of each such property and allocated pursuant to Section 4.1 of the Agreement.

        E.    The provisions of the Agreement (including this Exhibit A and the other Exhibits to the Agreement) relating to the maintenance of Capital Accounts are intended to comply with Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such Regulations. In the event the Trustee shall determine that it is prudent to modify the manner in which the Capital Accounts, or any debits or credits thereto (including, without limitation, debits or credits relating to liabilities which are secured by contributed or distributed property or which are assumed by the Trust, the Trustee, or the Unitholders) are computed in order to comply with such Regulations, the Trustee may make such modification without regard to Article 12 of the Agreement, provided that it is not likely to have a material effect on the amounts distributable to any Person pursuant to Article 11 of the Agreement upon the dissolution of the Trust. The Trustee also shall (i) make any adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Unitholders and the amount of Trust capital reflected on the Trust's balance sheet, as computed for book purposes, in accordance with Regulations Section 1.704-1(b)(2)(iv)(q), and (ii) make any appropriate modifications in the event unanticipated events might otherwise cause this Agreement not to comply with Regulations Section l.704-1(b).


        Section 2.
    No Interest.     

        No interest shall be paid by the Trust on Capital Contributions or on balances in Unitholders' Capital Accounts.


        Section 3.
    No Withdrawal.     

        No Unitholder shall be entitled to withdraw any part of its Capital Contribution or his Capital Account or to receive any distribution from the Trust, except as provided in Articles 2, 3 and 11 of the Agreement.

B-51

B-52



        Section 2.
    Allocations for Tax Purposes.     

        A.    Except as otherwise provided in this Section 2, for federal income tax purposes, each item of income, gain, loss and deduction shall be allocated among the Unitholders in the same manner as its correlative item of "book" income, gain, loss or deduction is allocated pursuant to Section 4.1 of the Agreement and Section 1 of this Exhibit B.

        B.    In an attempt to eliminate Book-Tax Disparities attributable to a Contributed Property or Adjusted Property, items of income, gain, loss, and deduction shall be allocated for federal income tax purposes among the Unitholders as follows:

B-53


        C.    To the extent Treasury Regulations promulgated pursuant to Section 704(c) of the Code permit a partnership to utilize alternative methods to eliminate the disparities between the Carrying Value of property and its adjusted basis, the Trustee shall, subject to the following, have the authority to elect the method to be used by the Trust and such election shall be binding on all Unitholders provided that, to the extent that the Trustee has agreed to use a particular method with respect to a Contributed Property, the Trustee shall be bound by such agreement (including, without limitation, the provisions set forth in Exhibit D and/or Exhibit F hereto) pursuant to the terms thereof.

B-54

[RESERVED]

B-55



EXHIBIT D

TAX PROTECTION AGREEMENT

Background

        In connection with the closing of the merger of Charles E. Smith Residential Realty, L.P. ("SRW Partnership"), with and into the Trust pursuant to the Agreement and Plan of Merger, dated as of May 3, 2001, by and among the Trustee, the Trust, Charles E. Smith Residential Realty, Inc. ("SRW") and SRW Partnership (the "Merger Agreement") (the "SRW Merger"), the Trust is making certain undertakings to the former limited partners of SRW Partnership who became Unitholders of the Trust as a result of the SRW Merger (the "Former SRW Limited Partners"). The specific agreements between the Trust and SRW Partnership with respect to these various matters are described below.

Specific Agreements


        1.
    Definitions.     All capitalized terms used and not otherwise defined in this Exhibit D shall have the meaning set forth in the Declaration of Trust. As used herein, the following terms have the following meanings:

B-56



        2.
    Restrictions on Dispositions of Protected Properties.     

B-57



        3.
    Prohibition on Repayment or Prepayment of Existing Nonrecourse Debt.     

B-58


B-59


B-60



        4.
    Remedies for Breach.     

B-61


B-62



        5.
    Opportunity for SRW Partners to Enter into Deficit Restoration Obligations.     Without limiting any of the obligations of the Trust under this Agreement, the Trust shall consider in good faith a request by an SRW Partner to enter into an agreement with the Trust to bear the economic risk of loss as to a portion of the Trust's recourse indebtedness by undertaking an obligation to restore a portion of its negative capital account balance upon liquidation of such SRW Partner's interest in the Trust, if such SRW Partner shall provide information from its professional tax advisor satisfactory to the Trust showing that, in the absence of such agreement, such SRW Partner likely would not be allocated from the Trust sufficient indebtedness under Section 752 of the Code and the at-risk provisions under Section 465 of the Code to avoid the recognition of gain (other than gain required to be recognized by reason of actual cash distributions from the Trust). The Trust and its professional tax advisors shall cooperate in good faith with such SRW Partner and its professional tax advisors to provide such information regarding the allocation of the Trust liabilities and the nature of such liabilities as is reasonably necessary in order to determine the SRW Partner's adjusted tax basis in its Units and at-risk amount. In deciding whether or not to grant such a request, the Trust shall be entitled to take into account all factors related to the Trust, including, without limitation, the existing and anticipated debt structure of the Trust, the tax situations of all other Unitholders, including the Trustee (individually and as a group), and the effect that granting such a request might have on their tax situation, and the anticipated long-term business needs of the Trust. The Trust's only obligation with respect to any such request from an SRW Partner pursuant to this Section 5 shall be to act in good faith. In the event the Trust fails to act in good faith with respect to any such request, the exclusive remedy of the SRW Partner who made such request shall be an action for specific performance, with no entitlement to monetary damages.


        6.
    Section 708 Termination; Section 704(c) Method.     

B-63



        7.
    Allocations of Liabilities Pursuant to Regulations Under Section 752.     All tax returns prepared by the Trust during the Protected Period shall allocate liabilities of the Trust for purposes of Section 752 and the Treasury Regulations thereunder taking into account the following:

B-64


        In addition, the Trust shall not make available after the date of the SRW Merger, whether pursuant to an agreement entered into after such date or otherwise, to any other Unitholder a method of allocating "excess nonrecourse liabilities" of the Trust that is more favorable than that made available to such SRW Partners without making such method available to the SRW Partners on a pro rata basis with such other Unitholders.

        Notwithstanding the provision of this Exhibit D, the Trust shall not be required to make allocations of Nonrecourse Liabilities or Partner Nonrecourse Debt to the SRW Partners as set forth in this Exhibit D if and to the extent that, as a result of a change in Section 752 of the Code or the Treasury Regulations occurring after the date hereof, the Trust obtains an opinion of Mayer Brown & Platt or KPMG Peat Marwick (or another comparable firm of attorneys or accountants) to the effect that, as a result of such change, there no longer is "substantial authority" (within the meaning of Section 6662(d)(2)(B)(i)) of the Code for such allocation; provided that the Trust shall provide to Mr. Robert H. Smith and Mr. Robert P. Kogod (or in the event of their death or disability, their executor, guardian or custodian, as applicable), notice of such determination, together with a copy of such opinion, and if, within forty-five (45) days after the receipt thereof, the Trust is provided an opinion of Hogan & Hartson LLP or Arthur Andersen LLP (or another comparable firm of attorneys or accountants) to the effect that, notwithstanding such change, there continues to be "substantial authority" (within the meaning of Section 6662(d)(2)(B)(i) of the Code) for such allocations, the Trust shall continue to make allocations of Nonrecourse Liabilities or Partner Nonrecourse Debt to the SRW Partners as set forth in this Exhibit D.

        If a change in the Trust's allocations of Nonrecourse Liabilities or Partner Nonrecourse Debt to the SRW Partners is required by reason of circumstances described in the preceding sentence, the Trust and its professional tax advisors shall cooperate in good faith with Messrs. Robert H. Smith and Robert P. Kogod (or in the event of their death or disability, their executor, guardian or custodian, as

B-65



applicable) and their professional tax advisors to develop alternative allocation arrangements and/or other mechanisms that protect the federal income tax positions of the SRW Partners in the manner contemplated by the allocations of Nonrecourse Liabilities or Partner Nonrecourse Debt to the SRW Partners as set forth in this Exhibit D.


        8.
    Other Agreements With SRW Partners.     Pursuant to the Merger Agreement, the Trustee, the Trust, SRW, and SRW Partnership will enter into an Assignment and Assumption Agreement, dated as of October 31, 2001, pursuant to which the Trust will assume certain obligations of SRW Partnership made pursuant to certain tax protection agreements (the "SRW Tax Protection Agreements"). A list of those SRW Tax Protection Agreements is set forth on Schedule 5 to this Exhibit D.


        9.
    Requirement for Delivery of Evidence of Filing of Form 8832.     Within 30 days following the SRW Merger, the Trustee shall provide to Messrs. Smith and Kogod, as representatives of the SRW Partners, evidence, in the form of a certified mail return receipt, that the Trust filed with the Internal Revenue Service Form 8832 electing pursuant to Treasury Regulation § 301.7701-3(c)(1)(i) to be treated either as a domestic eligible entity with a single owner electing to be disregarded as a separate entity or a partnership, as applicable, not later than one day prior to the closing of the SRW Merger.


        10.
    Amendment of this Agreement.     This Agreement may not be amended, directly or indirectly (including by reason of a merger between the Trust and another entity) except by a written instrument signed by the Trustee and approved by the SRW Partners holding seventy-six percent (76%) of the then outstanding Protected Units; provided, however, that any amendment that would permit a sale of a Protected Property in violation of Section 2 or the refinancing of debt in violation of Section 3, shall not be permitted without the written approval of holders of seventy-six percent (76%) of the then outstanding Protected Units held by SRW Partners that would be adversely affected by such actions.


        11.
    Modification of Section 5.8 of Annex A With Respect to Holders of Protected Units.     For purposes of applying Section 5.8.B. of Annex A to the Declaration of Trust with respect to all SRW Partners who hold Protected Units, that Section shall be applied by substituting the phrase "provided that the Trustee has acted in good faith and pursuant to its authority under this Agreement" for the phrase "unless the Trustee has acted in bad faith and the act or omission was material to the matter giving rise to the loss, liability or benefit pursuant to its authority under the Agreement." For purposes of applying Section 5.8.A. of Annex A to the Declaration of Trust with respect to all SRW Partners who hold Protected Units, that Section shall be applied by substituting the following therefor:

B-101



EXHIBIT F

DESIGNATION OF THE PREFERENCES, REDEMPTION AND OTHER RIGHTS,
VOTING POWERS, RESTRICTIONS, AND LIMITATIONS
AS TO SERIES O PREFERRED UNITS

As of            , 2007

        Under the authority granted to it by Article 2, Section 1(c) of the Articles of Restatement of the Amended and Restated Declaration of Trust of Archstone-Smith Operating Trust, a Maryland real estate investment trust (the "Trust"), dated as of May 19, 2006, as amended, supplemented or modified (the "Declaration"), the Trust hereby establishes an additional class of Units designated and entitled the "Series O Preferred Units" (the "Series O Preferred Units"), for issuance by the Trust in accordance with the Agreement and Plan of Merger, dated as of May 28, 2007, by and among the Trust, Archstone-Smith Trust, River Holding, LP, River Acquisition (MD), LP, and River Trust Acquisition (MD), LLC (the "Merger Agreement"). Capitalized terms used in this Exhibit F and not otherwise defined herein shall have the meanings assigned in the Declaration.


        A.
    Issuance of Series O Preferred Units in the Merger.     On the Closing Date, Series O Preferred Units shall be issued by the Trust in exchange for Class A-1 common units in the Trust outstanding immediately prior to the Operating Trust Merger Effective Time (as defined in the Merger Agreement). Thereafter, additional Series O Preferred Units shall be issued only pursuant to the terms of the Series Q-1 Preferred Units and Series Q-2 Preferred Units.


        B.
    Distributions.     

          (i)  Holders of then outstanding Series O Preferred Units shall be entitled to receive, when, as and if authorized by the Trustee and declared by the Trust, out of Available Cash, cumulative preferential distributions payable in cash in an amount per annum per Series O Preferred Unit equal to the applicable Distribution Rate times the Stated Value, but not in excess of the cumulative income allocated to the Holders pursuant to Section C (the "Distribution Amount"). Distributions shall begin to accumulate and shall be fully cumulative from the Closing Date, whether or not in any Distribution Period or Periods there shall be funds of the Partnership legally available for the payment of such distributions, and shall be payable quarterly, when, as and if authorized by the Trustee and declared by the Trust, in arrears on each Distribution Date. Each such distribution shall be payable in arrears to the holders of record of Series O Preferred Units as they appear in the records of the Trust at the close of business on such record dates, not less than 10 nor more than 50 days preceding the applicable Distribution Date, as shall be fixed by the Trustee. Accumulated and unpaid distributions for any past Distribution Periods may be declared and paid at any time and for such interim periods, without reference to any regular Distribution Date, to holders of record on such date, not less than 10 nor more than 50 days preceding the payment date thereof, as may be fixed by the Trustee. Any distribution made on the Series O Preferred Units shall first be credited against the earliest accumulated but unpaid distribution due with respect to Series O Preferred Units which remains payable.

         (ii)  The initial Distribution Period will include a partial distribution for the period from the Closing Date until [            ] 14, 20    . The amount of distributions payable for such period, or any other period shorter than a full Distribution Period, on the Series O Preferred Units shall be computed on the basis of a 360-day year of twelve 30-day months. For any Distribution Period in which the Increased Rate applies, the Distribution Amount for such Distribution Period shall be equal to the product of the Stated Value times the sum of: (x) the product of (A) the Base Rate divided by four, times (B) the number of days during the Distribution Period when the Base Rate is in effect (as provided in the definition of Distribution Rate) divided by (iii) the total number of days in the Distribution Period, plus (y) the product of (A) the Increased Rate divided by four times (B) the number of days during the Distribution Period when the Increased Rate is in effect (as provided in the definition of Distribution

B-102



Rate) divided by (iii) the total number of days in the Distribution Period. Holders of Series O Preferred Units shall not be entitled to any distributions, whether payable in cash, property or shares, in excess of cumulative distributions, as herein provided, on the Series O Preferred Units.

        (iii)  Distributions on the Series O Preferred Units which are due but unpaid will accumulate and compound quarterly at the applicable Distribution Rate in effect from time to time, whether or not there is sufficient Available Cash for such distributions and whether or not such distributions are authorized. Accumulated but unpaid distributions on the Series O Preferred Units will accumulate as of the Distribution Date on which they first become payable.

        (iv)  So long as any Series O Preferred Units are outstanding, no distributions, except as described in the immediately following sentence, shall be declared or paid or set apart for payment on any class or series of Parity Units for any period unless full cumulative distributions have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for such payment on the Series O Preferred Units for all Distribution Periods terminating on or prior to the Distribution Payment Date on such class or series of Parity Units. When distributions are not paid in full or a sum sufficient for such payment is not set apart, as aforesaid, all distributions declared upon Series O Preferred Units and all distributions declared upon any other class or series of Parity Units shall be declared ratably in proportion to the respective amounts of distributions accumulated and unpaid on the Series O Preferred Units and accumulated and unpaid on such Parity Units.

         (v)  So long as any Series O Preferred Units are outstanding, no distributions (other than distributions paid solely in shares of, or options, warrants or rights to subscribe for or purchase shares of, Junior Units) shall be declared or paid or set apart for payment or other distribution shall be declared or made or set apart for payment upon Junior Units, nor shall any Junior Units be redeemed, purchased or otherwise acquired (other than a redemption, purchase or other acquisition of Common Units made pursuant to an employee incentive or benefit plan of the Trustee, the Trust or any subsidiary of the Trust) for any consideration (or any moneys be paid to or made available for a sinking fund for the redemption of any Junior Units) by the Trust, directly or indirectly (except by conversion into or exchange for Junior Units), unless in each case (i) the full cumulative distributions on all outstanding Series O Preferred Units (determined without regard to the provision in Section B(i) limiting distributions to cumulative income allocated under Section C) and any other Parity Units of the Trust shall have been or contemporaneously are declared and paid or declared and set apart for payment for all past Distribution Periods with respect to the Series O Preferred Units and all past distribution periods with respect to such Parity Units, (ii) sufficient funds shall have been or contemporaneously are declared and paid or declared and set apart for the payment of the distribution for the current Distribution Period with respect to the Series O Preferred Units (determined without regard to the provision in Section B(i) limiting distributions to cumulative income allocated under Section C) and the current distribution period with respect to such Parity Units and (iii) all amounts payable with respect to Redemption Notices theretofore delivered in accordance with Section E or F shall have been paid in full or sufficient funds shall have been set apart for payment thereof on the Redemption Date. Notwithstanding anything to the contrary herein (including the provision in Section B(i) limiting distributions to cumulative income allocated under Section C), the Trustee may, in its sole and absolute discretion, authorize, and cause the Trust to declare and pay or declare and set apart for payment, the full cumulative distributions on all outstanding Series O Preferred Units (determined without regard to the provision in Section B(i) limiting distributions to cumulative income allocated under Section C).

        (vi)  So long as any Series O Preferred Units are outstanding, if and so long as distributions are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series O Preferred Units, all distributions authorized upon the Series O Preferred Units shall be authorized and paid pro rata so that the amount of distributions authorized and paid per Series O Preferred Unit shall in all cases bear to each other the same ratio that accumulated distributions per Series O Preferred

B-103



Unit bear to each other. No interest shall be payable in respect of any distribution payment or payments on Series O Preferred Units which may be in arrears (but as set forth in Section B(iii), distributions on the Series O Preferred Units that are due but unpaid will accumulate and compound quarterly at the Distribution Rate).

       (vii)  No distributions on the Series O Preferred Units shall be authorized by the Trustee or paid or set apart for payment by the Trust at such times as any agreement of the Trust, including any agreement relating to its indebtedness, prohibits such authorization, payment or setting apart for payment or provides that such authorization, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such authorization or payment shall be restricted or prohibited by law.


        C.
    Allocations.     Notwithstanding anything contained in the Declaration to the contrary, including Article 4 of Annex A thereof, to the fullest extent permitted by applicable law (i) each Holder shall be deemed to have a Capital Account as of the date hereof equal to the product of the Stated Value multiplied by the number of Series O Preferred Units held by such Holder; (ii) the Trust's net income and gain shall first be allocated to the Holders of the Series O Preferred Units each year until the aggregate amount of net income and gain allocated to each of the Holders is equal to the sum of (a) all distributions such Holder is entitled to receive pursuant to Section B of this Exhibit F from the date of this Exhibit F to the date of such allocation (determined without regard to the provision in Section B(i) limiting distributions to cumulative income allocated under this Section C), plus (b) any losses allocated to such Holder pursuant to this Section C from the date of this Exhibit F to the date of such allocation and not previously made up by income or gain allocations pursuant to this Section C; (iii) all remaining net income and gain of the Trust shall be allocated to the holders of Trust Interests other than the Series O Preferred Units; (iv) all losses of the Trust shall be allocated to the holders of the Trust Interests other than the Series O Preferred Units until the Capital Account of each such holder of such Trust Interests has been reduced to zero; (v) losses of the Trust next shall be allocated to the Holders until the Capital Accounts of such Holders are reduced to zero; and (vi) any remaining losses of the Trust shall be allocated to the Trustee in its capacity as a holder of Units (other than Series O Preferred Units) held by the Trustee. Allocations to holders of Units other than the Holders shall be made among such other Holders in accordance with Article IV of the Annex to the Declaration. In connection with any liquidation, dissolution or winding up of the affairs of the Trust, whether voluntary or involuntary, and immediately prior to a redemption of Series O Preferred Units by the Trust pursuant to either Section E or Section F (but only if the full cumulative distributions on the outstanding Series O Preferred Units (determined without regard to the provision in Section B(i) limiting distributions to cumulative income allocated under Section C) exceed the actual distributions on the outstanding Series O Preferred Units), any unsold property of the Trust shall be revalued to its fair market value and any positive adjustment shall be allocated as income or gain and any negative adjustment shall be allocated as loss.


        D.
    Liquidation Preference.     

          (i)  In the event of any liquidation, dissolution or winding up of the affairs of the Trust, whether voluntary or involuntary, before any payment or distribution of the assets of the Trust shall be made or set apart for the holders of Junior Units, notwithstanding anything in the Declaration to the contrary, including Section 11.2 of Annex A thereof, the Holders shall be entitled to receive an amount per Series O Preferred Unit equal to (i) the sum of the Stated Value plus (ii) an amount equal to all accumulated and unpaid distributions which such Holder is entitled to receive under Section B (whether or not declared) as accumulated to the date of final distribution to such Holders; but such Holders shall not be entitled to any further payment. For the purposes of this Section D, (i) a consolidation or merger of the Trust with or into one or more partnerships, trusts, corporations, limited liability companies, real estate investment trusts or other entities or of one or more partnerships, trusts, corporations, limited liability companies, real estate investment trusts or other entities with or into the Trust, (ii) a sale, lease or conveyance of all or substantially all of the Trust's property or business or

B-104



(iii) a statutory share exchange shall not be deemed to be a liquidation, dissolution or winding up, voluntary or involuntary, of the Trust.

         (ii)  In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, the legally available assets of the Trust are insufficient to pay the full amount of the liquidating distributions on all outstanding Series O Preferred Units and required liquidating payments on the Parity Units, then such assets shall be distributed ratably among the Holders and the holders of the Parity Units in proportion to the full liquidating distributions to which the Holders and the holders of the Parity Units would otherwise respectively be entitled if all amounts payable thereon were paid in full.


        E.
    Redemption at Holder's Option for Cash.     

          (i)  Commencing on the fifth anniversary of the Closing Date, each Holder shall have the right (the "Preferred Redemption Right") to require the Trust to redeem on the Preferred Redemption Date some or all of the Series O Preferred Units held by such Holder, as specified by such Holder in its Redemption Notice, at a redemption price per Series O Preferred Unit equal to the Redemption Price to be paid in cash by the Trust; provided, however, that the Trustee may, in its sole and absolute discretion, unless expressly prohibited by the terms of any applicable tax protection or other agreement, elect to assume directly and satisfy a Preferred Redemption Right by paying to the Holder cash equal to the Redemption Price; provided further, that if the Trustee shall exercise its right to satisfy the Preferred Redemption Right in the manner described in the immediately previous proviso and shall fully perform its obligations in connection therewith, the Trust shall have no right or obligation to pay any amount to the Holder with respect to such Holder's exercise of its Preferred Redemption Right, and each such Holder, the Trust and the Trustee shall, for federal income tax purposes, treat the transaction between the Trustee and such Holder as a sale of the Holder's Series O Preferred Units to the Trustee. The Preferred Redemption Right shall be exercised pursuant to a Redemption Notice delivered to the Trustee by a Holder who is exercising the redemption right (the "Preferred Redeeming Unitholder"), which Redemption Notice can be delivered on or after the fifth anniversary of the Closing Date. Subject to subsections (ii) and (viii) of this Section E, a Holder may exercise the Preferred Redemption Right from time to time but no more frequently than once in any twelve calendar month period with respect to part or all of the Series O Preferred Units that it owns, as selected by the Holder, provided that a Holder may not exercise the Preferred Redemption Right for less than one thousand (1,000) Series O Preferred Units unless such Holder then holds less than one thousand (1,000) Series O Preferred Units, in which event the Redeeming Unitholder must exercise the Preferred Redemption Right for all of the Units held by such Holder, and provided further that, with respect to a Holder which is an entity, such Holder may, no more frequently than once in any twelve calendar month period, exercise the Redemption Right for less than one thousand (1,000) Series O Preferred Units without regard to whether or not such Holder is exercising the Preferred Redemption Right for all of the Series O Preferred Units held by such Holder as long as such Holder is exercising the Preferred Redemption Right on behalf of one or more of its equity owners in respect of one hundred percent (100%) of such equity owners' interests in such Holder.

         (ii)  Notwithstanding the foregoing, in no event shall the Trust be required to redeem more than                        (1) Series O Preferred Units in any twelve calendar month period (the "Annual Redemption Limit"). If, and to the extent that, Notices of Redemption are delivered to the Trustee that would require the redemption of Series O Preferred Units in excess of the Annual Redemption Limit, the Trust shall redeem the Series O Preferred Units subject to such Redemption Notices in the order in


(1)
One-third of the total number of Series O Preferred Units actually issued at the closing of the Merger.

B-105


which the Redemption Notices are received until the Annual Redemption Limit is reached (with the Series O Preferred Units subject to Redemption Notices received on the same date by the Trust redeemed in proportion to the total number of Series O Preferred Units subject to such Redemption Notices to the extent that the redemption of all Series O Preferred Units subject to Redemption Notices received on such date would exceed the Annual Redemption Limit). Subject to subsection (viii) of this Section E, if and to the extent that any Series O Preferred Units are not redeemed on the date that otherwise would be the applicable Redemption Date due to the Annual Redemption Limit, the Preferred Redemption Date for such Series O Preferred Units shall be the first Business Day of the first calendar month in which such Series O Preferred Units could be redeemed without causing the Annual Redemption Limit to be exceeded.

        (iii)  Notwithstanding that the Preferred Redemption Right otherwise is exercisable only commencing on the fifth anniversary of the Closing Date, in the event of the earlier death of a Holder or, in the case of a Holder that is a trust that is includible in the taxable estate of an individual, the death of such individual, the Preferred Redemption Right shall be exercisable immediately by the personal representative of such Holder's estate or the trustee of such trust, as the case may be, for the 120 days following such death upon 30 days written notice to the Trust.

        (iv)  In the event any applicable redemption date shall not be a Business Day, then payment of the Redemption Price need not be made on such redemption date but may be made on the next succeeding Business Day with the same force and effect as if made on such applicable redemption date and no interest, additional distributions or other sum shall accumulate on the amount payable for the period from and after such redemption date to such next succeeding Business Day.

         (v)  If notice of redemption of any Series O Preferred Unit has been given and if the funds necessary for such redemption have been set aside by the Trust for the benefit of the holders of any Series O Preferred Units so called for redemption, then (A) on and after the applicable redemption date, distributions will cease to accumulate on such Series O Preferred Units and (B) on and after the applicable redemption date, such Series O Preferred Units shall be deemed to be no longer outstanding and all rights of the holders of such Series O Preferred Units will terminate, except the right to receive the Redemption Price and except for the right, if any, to receive payment of any Tax Protection Amount with respect to events occurring prior to the closing of the redemption.

        (vi)  To the fullest extent permitted by applicable law, on the applicable date of redemption, (1) the Holders whose Series O Preferred Units are redeemed pursuant to this Section E, (A) shall have no further rights in respect of such Series O Preferred Units (including without limitation any right to receive any distributions paid after the applicable date of redemption), other than the right to receive the Redemption Price (and the right to receive any Tax Protection Amount, if any, then due and owing) and (B) shall no longer be Unitholders of the Trust in respect of such redeemed Series O Preferred Units and (2) any redeemed Series O Preferred Units shall no longer be deemed to be outstanding, whether or not any certificates (if any) evidencing such Series O Preferred Units shall have been received by the Trust.

       (vii)  As a condition to exercising the Preferred Redemption Right, and any such exercise shall only be effective if concurrently with such exercise, Holders of Series O Preferred Units shall agree, without additional consideration, to release, with respect to all Series O Preferred Units owned directly by the Holder, the Trust and its respective former, current or future general or limited partners, stockholders, managers, members, directors, officers, Affiliates, agents or representatives from any claims under any Tax Protection Agreement with respect to any income or gain that is recognized as a result of such Holders' sale of Series O Preferred Units to the Trust pursuant to the Preferred Redemption Right and receipt of the Redemption Price. In no event shall a Holder be required to waive any claim that it had under any Tax Protection Agreement with respect to or as a result of (a) any transaction or event occurring prior to the closing of the Redemption Date, whether or not asserted at the Redemption Date, or (b) if the Holder does not have all of the Series O Preferred Units owned by such Holder

B-106



redeemed, events occurring on or following the Redemption Date that cause such Holder to recognize income or gain for federal, state or local income tax purposes with respect to its Series O Preferred Units not redeemed on such Redemption Date.

      (viii)  Avoidance of "Publicly Traded Partnership" Status. In connection with monitoring the transfers of interests in the Trust to determine (i) if such interests are being traded on an "established securities market" or a "secondary market (or the substantial equivalent thereof)" within the meaning of Section 7704 of the Code and (ii) whether additional transfers of interests would result in the Trust being unable to qualify for at least one of the "safe harbors" set forth in Regulations Section 1.7704-1 (or such other guidance subsequently published by the IRS setting forth safe harbors under which interests will not be treated as "readily tradable on a secondary market (or the substantial equivalent thereof)" within the meaning of Section 7704 of the Code) (the "Safe Harbors"), the Trustee shall take all steps reasonably necessary or appropriate to prevent any trading of interests or any recognition by the Trust of transfers made on such markets and, except as otherwise provided herein, to insure that at least one of the Safe Harbors is met, including limiting or restricting the right of Holders to exercise the Preferred Redemption Right to the extent that, in the absence of such limitation or restriction, there is a significant risk that the Trust will be treated as a "publicly traded partnership" and, by reason thereof, will be taxable as a corporation.

        (ix)  In the event that the Trustee (or its direct or indirect parent) is (as the result of any merger, acquisition or otherwise) a real estate investment trust (a "REIT") with publicly traded equity securities, the Trustee shall have the right to amend this Section E and any provision of Exhibit F as necessary to provide the REIT the option, in lieu of paying the Redemption Price in cash, to issue an amount of publicly traded stock in such public REIT with a fair market value at the time of redemption, as determined by the Trustee in good faith, equal to the Redemption Price to any redeeming holder; provided that this right of substitution shall be available only if either (1) the shares of stock to be issued to such Holder pursuant hereto are registered with the Securities and Exchange Commission for resale by the redeeming Holder or (2) the redeeming Holder is granted customary resale registration rights with respect to such shares of stock.

The stockholder's stock is to be acquired in a share exchange;

(3)
The corporation transfers its assets in a manner requiring action under § 3-105(e) of this title;

(4)
The corporation amends its charter in a way which alters the contract rights, as expressly set forth in the charter, of any outstanding stock and substantially adversely affects the stockholder's rights, unless the right to do so is reserved by the charter of the corporation; or

(5)
The transaction is governed by § 3-602 of this title or exempted by § 3- 603(b) of this title.

(b)
Basis of fair value.—

(1)
Fair value is determined as of the close of business:

(ii)
With respect to any other transaction, on the day the stockholders voted on the transaction objected to.

(2)
Except as provided in paragraph (3) of this subsection, fair value may not include any appreciation or depreciation which directly or indirectly results from the transaction objected to or from its proposal.

(3)
In any transaction governed by § 3-602 of this title or exempted by § 3- 603(b) of this title, fair value shall be value determined in accordance with the requirements of § 3-603(b) of this title.

C-1


(c)
When right to fair value does not apply.—Unless the transaction is governed by § 3-602 of this title or is exempted by § 3-603(b) of this title, a stockholder may not demand the fair value of the stockholder's stock and is bound by the terms of the transaction if:

(1)
The stock is listed on a national securities exchange, is designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc., or is designated for trading on the NASDAQ Small Cap Market:

(i)
With respect to a merger under § 3-106 of this title of a 90 percent or more owned subsidiary with or into its parent corporation, on the date notice is given or waived under § 3-106; or

(ii)
With respect to any other transaction, on the record date for determining stockholders entitled to vote on the transaction objected to;

(2)
The stock is that of the successor in a merger, unless:

(i)
The merger alters the contract rights of the stock as expressly set forth in the charter, and the charter does not reserve the right to do so; or

(ii)
The stock is to be changed or converted in whole or in part in the merger into something other than either stock in the successor or cash, scrip, or other rights or interests arising out of provisions for the treatment of fractional shares of stock in the successor;

(3)
The stock is not entitled, other than solely because of § 3-106 of this title, to be voted on the transaction or the stockholder did not own the shares of stock on the record date for determining stockholders entitled to vote on the transaction;

(4)
The charter provides that the holders of the stock are not entitled to exercise the rights of an objecting stockholder under this subtitle; or

(5)
The stock is that of an open-end investment company registered with the Securities and Exchange Commission under the Investment Company Act of 1940 and the value placed on the stock in the transaction is its net asset value.

§ 3-203 Procedure by stockholder

(a)
Specific duties.—A stockholder of a corporation who desires to receive payment of the fair value of the stockholder's stock under this subtitle:

(1)
Shall file with the corporation a written objection to the proposed transaction:

(i)
With respect to a merger under § 3-106 of this title of a 90 percent or more owned subsidiary with or into its parent corporation, within 30 days after notice is given or waived under § 3-106; or

(ii)
With respect to any other transaction, at or before the stockholders' meeting at which the transaction will be considered or, in the case of action taken under § 2-505(b) of this article, within 10 days after the corporation gives the notice required by § 2-505(b) of this article;

(2)
May not vote in favor of the transaction; and

(3)
Within 20 days after the Department accepts the articles for record, shall make a written demand on the successor for payment for the stockholder's stock, stating the number and class of shares for which the stockholder demands payment.

(b)
Failure to comply with section.—A stockholder who fails to comply with this section is bound by the terms of the consolidation, merger, share exchange, transfer of assets, or charter amendment.

C-2


§ 3-204 Effect of demand on dividend and other rights

A stockholder who demands payment for his stock under this subtitle:

§ 3-205 Withdrawal of demand

A demand for payment may be withdrawn only with the consent of the successor.

§ 3-206 Restoration of dividend and other rights

(a)
When rights restored.—The rights of a stockholder who demands payment are restored in full, if:

(1)
The demand for payment is withdrawn;

(2)
A petition for an appraisal is not filed within the time required by this subtitle;

(3)
A court determines that the stockholder is not entitled to relief; or

(4)
The transaction objected to is abandoned or rescinded.

(b)
Effect of restoration.—The restoration of a stockholder's rights entitles him to receive the dividends, distributions, and other rights he would have received if he had not demanded payment for his stock. However, the restoration does not prejudice any corporate proceedings taken before the restoration.

§ 3-207 Notice and offer to stockholders

(a)
Duty of successor.—

(1)
The successor promptly shall notify each objecting stockholder in writing of the date the articles are accepted for record by the Department.

(2)
The successor also may send a written offer to pay the objecting stockholder what it considers to be the fair value of his stock. Each offer shall be accompanied by the following information relating to the corporation which issued the stock:

(i)
A balance sheet as of a date not more than six months before the date of the offer;

(ii)
A profit and loss statement for the 12 months ending on the date of the balance sheet; and

(iii)
Any other information the successor considers pertinent.

(b)
Manner of sending notice.—The successor shall deliver the notice and offer to each objecting stockholder personally or mail them to him by certified mail, return receipt requested, bearing a postmark from the United States Postal Service, at the address he gives the successor in writing, or, if none, at his address as it appears on the records of the corporation which issued the stock.

§ 3-208 Petition for appraisal; consolidation of proceedings; joinder of objectors

(a)
Petition for appraisal.—Within 50 days after the Department accepts the articles for record, the successor or an objecting stockholder who has not received payment for his stock may petition a court of equity in the county where the principal office of the successor is located or, if it does not

C-3


(b)
Consolidation of suits; joinder of objectors.—

(1)
If more than one appraisal proceeding is instituted, the court shall direct the consolidation of all the proceedings on terms and conditions it considers proper.

(2)
Two or more objecting stockholders may join or be joined in an appraisal proceeding.

§ 3-209 Notation on stock certificate

(a)
Submission of certificate.—At any time after a petition for appraisal is filed, the court may require the objecting stockholders parties to the proceeding to submit their stock certificates to the clerk of the court for notation on them that the appraisal proceeding is pending. If a stockholder fails to comply with the order, the court may dismiss the proceeding as to him or grant other appropriate relief.

(b)
Transfer of stock bearing notation.—If any stock represented by a certificate which bears a notation is subsequently transferred, the new certificate issued for the stock shall bear a similar notation and the name of the original objecting stockholder. The transferee of this stock does not acquire rights of any character with respect to the stock other than the rights of the original objecting stockholder.

§ 3-210 Appraisal of fair value

(a)
Court to appoint appraisers.—If the court finds that the objecting stockholder is entitled to an appraisal of his stock, it shall appoint three disinterested appraisers to determine the fair value of the stock on terms and conditions the court considers proper. Each appraiser shall take an oath to discharge his duties honestly and faithfully.

(b)
Report of appraisers—Filing.—Within 60 days after their appointment, unless the court sets a longer time, the appraisers shall determine the fair value of the stock as of the appropriate date and file a report stating the conclusion of the majority as to the fair value of the stock.

(c)
Same—Contents.—The report shall state the reasons for the conclusion and shall include a transcript of all testimony and exhibits offered.

(d)
Same—Service; objection.—

(1)
On the same day that the report is filed, the appraisers shall mail a copy of it to each party to the proceedings.

(2)
Within 15 days after the report is filed, any party may object to it and request a hearing.

§ 3-211 Action by court on appraisers' report

(a)
Order of court.—The court shall consider the report and, on motion of any party to the proceeding, enter an order which:

(1)
Confirms, modifies, or rejects it; and

(2)
If appropriate, sets the time for payment to the stockholder.

(b)
Procedure after order.—

(1)
If the appraisers' report is confirmed or modified by the order, judgment shall be entered against the successor and in favor of each objecting stockholder party to the proceeding for the appraised fair value of his stock.

C-4


(c)
Judgment includes interest.—

(1)
Except as provided in paragraph (2) of this subsection, a judgment for the stockholder shall award the value of the stock and interest from the date as at which fair value is to be determined under § 3-202 of this subtitle.

(2)
The court may not allow interest if it finds that the failure of the stockholder to accept an offer for the stock made under § 3-207 of this subtitle was arbitrary and vexatious or not in good faith. In making this finding, the court shall consider:

(i)
The price which the successor offered for the stock;

(ii)
The financial statements and other information furnished to the stockholder; and

(iii)
Any other circumstances it considers relevant.

(d)
Costs of proceedings.—

(1)
The costs of the proceedings, including reasonable compensation and expenses of the appraisers, shall be set by the court and assessed against the successor. However, the court may direct the costs to be apportioned and assessed against any objecting stockholder if the court finds that the failure of the stockholder to accept an offer for the stock made under § 3-207 of this subtitle was arbitrary and vexatious or not in good faith. In making this finding, the court shall consider:

(i)
The price which the successor offered for the stock;

(ii)
The financial statements and other information furnished to the stockholder; and

(iii)
Any other circumstances it considers relevant.

(2)
Costs may not include attorney's fees or expenses. The reasonable fees and expenses of experts may be included only if:

(i)
The successor did not make an offer for the stock under § 3-207 of this subtitle; or

(ii)
The value of the stock determined in the proceeding materially exceeds the amount offered by the successor.

(e)
Effect of judgment.—The judgment is final and conclusive on all parties and has the same force and effect as other decrees in equity. The judgment constitutes a lien on the assets of the successor with priority over any mortgage or other lien attaching on or after the effective date of the consolidation, merger, transfer, or charter amendment.

§ 3-212 Surrender of stock

The successor is not required to pay for the stock of an objecting stockholder or to pay a judgment rendered against it in a proceeding for an appraisal unless, simultaneously with payment:

C-5


§ 3-213 Rights of successor with respect to stock

(a)
General rule.—A successor which acquires the stock of an objecting stockholder is entitled to any dividends or distributions payable to holders of record of that stock on a record date after the close of business on the day as at which fair value is to be determined under § 3-202 of this subtitle.

(b)
Successor in transfer of assets.—After acquiring the stock of an objecting stockholder, a successor in a transfer of assets may exercise all the rights of an owner of the stock.

(c)
Successor in consolidation, merger, or share exchange.—Unless the articles provide otherwise, stock in the successor of a consolidation, merger, or share exchange otherwise deliverable in exchange for the stock of an objecting stockholder has the status of authorized but unissued stock of the successor. However, a proceeding for reduction of the capital of the successor is not necessary to retire the stock or to reduce the capital of the successor represented by the stock.

C-6



PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

        Section 5.7A of Annex A to the registrant's new declaration of trust provides as follows with respect to indemnification of trustees:

        "The Trust shall indemnify each Indemnitee to the fullest extent provided by the Act from and against any and all losses, claims, damages, liabilities, joint or several, expenses (including, without limitation, attorneys fees and other legal fees and expenses), judgments, fines, settlements and other amounts arising from or in connection with any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative, incurred by the Indemnitee and relating to the operating trust or the trustee or the operation of, or the ownership of property by, the operating trust or the trustee as set forth in the registrant's new declaration of trust in which any such Indemnitee may be involved, or is threatened to be involved, as a party or otherwise, unless it is established by a final determination of a court of competent jurisdiction that: (i) the act or omission of the Indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty, (ii) the Indemnitee actually received an improper personal benefit in money, property or services, or (iii) in the case of a criminal proceeding, the Indemnitee had reasonable cause to believe that the act or omission was unlawful. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Indemnitee did not meet the requisite standard of conduct set forth in this Section 5.7A. The termination of any proceeding by conviction or upon a plea of nolo contendere or its equivalent, or an entry of an order of probation prior to judgment, creates a rebuttable presumption that the Indemnitee acted in a manner contrary to that specified in this Section 5.7A with respect to the subject matter of such proceeding. Any indemnification pursuant to this Section 5.7 shall be made only out of the assets of the operating trust, and any insurance proceeds from the liability policy covering the trustee and any Indemnitee, and neither the trustee nor any other Unitholder shall have any obligation to contribute to the capital of the operating trust or otherwise provide funds to enable the operating trust to fund its obligations under this Section 5.7."

        Section 5.8A of Annex A to the registrant's new declaration of trust provides as follows with respect to the limitation of liability of Trustees:

        Article 8, Section 1 of the registrant's new declaration of trust provides as follows with respect to the limitation of liability of officers:
