    the Articles of Incorporation relating to the number, classes, term of
  office and qualifications of directors, to require the approval of a
     majority of the common shares of Duke. This proposal is being presented

 5.  To consider and approve the 1999 Directors' Stock Option and Dividend
Increase Unit Plan of Duke.

SUMMARY 

THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE DETAILED      
INFORMATION APPEARING ELSEWHERE IN THIS JOINT PROXY STATEMENT AND PROSPECTUS,   
INCLUDING THE ANNEXES TO IT, OR INCORPORATED IN THIS DOCUMENT BY REFERENCE. WE  
URGE YOU TO REVIEW THE ENTIRE JOINT PROXY STATEMENT AND PROSPECTUS, INCLUDING   
ITS ANNEXES.                                                                    

QUESTIONS AND ANSWERS ABOUT THE MERGER                                          

Q: What are the benefits of the proposed merger?                        

  A: Duke and Weeks expect the combined company resulting from the merger to
  have the following characteristics, which are expected to create long-term
shareholder value:                                                      

  - the combined company will be the largest mixed office/industrial REIT in
    the United States, based on the amount of rentable space it will own and
its equity market capitalization;                                   

 - the combined company expects to improve its valuation relative to other
    REITs in the public market because for each of Duke and Weeks the merger
 should result in greater liquidity in its publicly traded securities,
 increased research coverage, a more diversified credit profile and an
enhanced institutional shareholder base;                            

- the combined company will have an experienced management team able to 
     leverage its skills over a broader base of assets and a large development
pipeline; and                                                       

- the combined company will have a more geographically diversified asset
base than either Duke or Weeks alone, which should reduce cash flow 
sensitivity to local economic cycles and provide more consistent    
development opportunities.                                          

Q: What are the detriments of the proposed merger?                      

A: Duke and Weeks expect the merger to have the following potential     
detriments to their shareholders:                                       

   - the exchange ratio of Duke common shares for Weeks common shares is fixed
at 1.38, which means that the Duke common shares that Weeks common  
      shareholders will receive in the merger may have a greater or lesser value
   than the value contemplated at the time the merger agreement was signed
because of fluctuations in the market price of Duke common shares;  

   - substantial management time and effort will be required to consummate the
merger and integrate the operations of the two companies; and       

- there is a risk that the benefits sought in the merger will not be    
obtained.                                                           

Q: Will Duke shareholders receive any shares as a result of the merger? 

A: No. Duke shareholders will continue to hold the same number of Duke  
shares they currently own.                                              

 Q: If I own preferred shares of Weeks, will any of the terms of my shares
change as a result of the merger?                                       

 A: No. Each preference share of Duke which you will receive in the merger
    will have terms substantially identical to the terms of your Weeks preferred
shares, including the dividend rate. The fact that a preference share of
Duke represents 1/1,000, of a preferred share of Duke does not mean that
your rights and benefits as preferred shareholders of Weeks are being   
    reduced in any way. The use of a preference share is simply a mechanism used
   to deliver shares in the merger having substantially identical terms to the
Weeks preferred shares without issuing more preferred shares than are   
authorized under Duke's Articles of Incorporation.                      

Q: What do I need to do now?

  A: After reading this joint proxy statement and prospectus, just mail your
 signed proxy card in the enclosed return envelope as soon as possible, so
    that your shares can be voted at the June 18, 1999 Duke shareholder meeting,
if you are a Duke shareholder, or at the June 18, 1999 Weeks shareholder
meeting, if you are a Weeks shareholder.                                

   Q: If my shares are held in "street name" by my broker, will my broker vote
my shares for me?                                                       

A: Your broker will vote your shares only if you provide instructions to
your broker on how to vote. You should contact your broker and ask what 
  directions your broker will need from you. Your broker will not be able to
vote your shares without instructions from you.                         

Q: Can I change my vote after I have mailed my signed proxy card?       

  A: Yes. You can change your vote at any time before your proxy is voted at
 the applicable shareholder meeting. You can do this in one of three ways.
First, you can send a written notice stating that you revoke your proxy.
Second, you can complete and submit a new proxy card, dated a later date
    than the first proxy card. Third, you can attend the appropriate meeting and
vote in person. Your attendance at the shareholder meeting will not,    
however, by itself revoke your proxy. If you hold your shares in "street
  name" and have instructed your broker to vote your shares, you must follow
directions received from your broker to change those instructions.      

Q: Should Weeks shareholders or Duke shareholders send in their stock   
certificates now?                                                       

A: No. If you are a Weeks shareholder, after the merger is completed you
will receive written instructions for exchanging your Weeks common and  
preferred shares for Duke common and preference shares, and any cash    
   payments you may be entitled to receive. If you are a Duke shareholder, you
should retain your certificates, as you will continue to hold the Duke  
shares you currently own.                                               

  Q: What happens to my distributions prior to the closing of the merger and
in the future?                                                          

    A: Both Weeks and Duke plan to continue to pay distributions on their common
shares until the closing of the merger consistent with their current    
   distribution policies. Both the Duke Board of Directors and the Weeks Board
   of Directors will continue to evaluate their respective financial condition
and earnings level, which could result in a change in the future        
distribution level. After the merger, Duke-Weeks plans to increase its  
    distributions to an annualized level of at least $1.48 per common share from
  Duke's current annualized distribution of $1.36 per common share. Based on
  the 1.38 exchange ratio, this would equal approximately $2.04 per existing
Weeks common share. It is expected that the first distribution by the   
  combined company will be paid in late August 1999. Duke-Weeks expects that
 it will pay distributions on its common shares at the end of May, August,
November and February of each year, which is when Duke has traditionally
paid distributions. Duke-Weeks intends to pay distributions in order to 
maintain its status as a real estate investment trust under the Internal
Revenue Code of 1986.                                                   

Q: What are the tax consequences of the merger?                         

A: We have structured the merger so that Duke, Weeks and our respective 
shareholders will not recognize any gain or loss for federal income tax 
  purposes in the merger, except in the case of cash to be received by Weeks
    shareholders in lieu of Duke fractional shares. As part of the closing, each
company will receive legal opinions confirming these tax consequences.  

Q: What will the tax basis of Weeks' shareholders be in the Duke common 
shares they receive in the merger?                                      

  A: Your tax basis in the Duke common and preference shares will equal your
  current tax basis in your Weeks common and preferred shares surrendered in
the exchange, decreased by your tax basis

Proposal--Material Federal Income Tax Consequences" on page 51.         

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

A: We hope to complete the merger on June 30, 1999, or as quickly as    
possible thereafter.                                                    

Q: Who can help answer my questions?

merger, you should contact:

Duke, which will be the surviving company in the merger, is a           
self-administered and self-managed real estate investment trust organized under 
Indiana law. Duke owns and leases industrial, office and retail properties      
throughout the Midwest, which it and its predecessors have been doing since     
1972. Duke has the largest commercial real estate operations in Indianapolis and
Cincinnati and is one of the largest real estate companies in the Midwest. As of
December 31, 1998, Duke owned interests in a diversified portfolio of 493 rental
properties comprising approximately 59.3 million square feet (including 40      
buildings and three expansions comprising approximately 7.2 million square feet 
under development). Substantially all of these properties are located in        
Indianapolis, Indiana; Cincinnati, Cleveland, and Columbus, Ohio; St. Louis,    
Missouri; Minneapolis, Minnesota; Chicago, Illinois; and Nashville, Tennessee.  
Also, as of December 31, 1998, Duke owned or controlled approximately 2,800     
acres of unencumbered land, which Duke believes could support the development of
approximately 43 million square feet of properties. In addition to its rental   
operations, Duke, through its service operations, provides leasing, management, 
construction, development and other real estate services for approximately 6.9  
million square feet of properties owned by third parties.

  Weeks is a self-administered and self-managed real estate investment trust
that was organized in 1994 under Georgia law to continue and expand the fully   
integrated real estate business previously conducted by Weeks and its           
affiliates. Since 1965, Weeks, together with its affiliates and predecessors,   
has developed, owned, managed, constructed and acquired primarily               
institutional-quality industrial and suburban office properties in select       
suburban markets in the southeast United States and Texas. As of December 31,   
1998, Weeks owned 371 properties, totaling approximately 31.6 million square    
feet, including 52 properties that were under development or in lease-up and    
excluding two properties that were under agreement to acquire. Weeks' properties
are located in Atlanta, Georgia; Nashville, Tennessee; Raleigh-Durham-Chapel    
Hill, North Carolina; Miami, Orlando, Jacksonville, Ft. Lauderdale and Tampa,   
Florida; Dallas, Texas; and Spartanburg, South Carolina. In addition, as of     
December 31, 1998, Weeks owned or controlled approximately 1,900 net useable    
acres of undeveloped land, which Weeks believes could support the development of
approximately 20 million square feet of properties.                             

THE COMBINED COMPANY                                                            

 Upon completion of the merger, the combined company is expected to have a
total pro forma market capitalization of approximately $5.2 billion, based on   
the closing price of Duke's common shares on February 26, 1999 (the last full   
trading day before the merger was publicly announced) and the outstanding       
principal amount of indebtedness of the two companies on December 31, 1998. The 
combined company will own interests in 864 industrial, office and retail        
properties (including properties under development), based on the real estate   
assets held by Duke and Weeks as of December 31, 1998. The combined real estate 
assets, including assets held by unconsolidated subsidiaries and joint ventures,
will consist of over 90 million square feet of industrial, office and retail    
properties serving approximately 5,000 tenants. Additionally, the combined      
company will own or control approximately 4,700 acres of undeveloped land with  
estimated future development potential of approximately 63 million square feet  
of industrial, office and retail properties. The name of the combined company   
for two years after the merger will be Duke-Weeks Realty Corporation. After that
two-year period, the name will be changed to Duke Realty Corporation, unless the
combined company's Board of Directors recommends against changing the name. The 
combined company will continue to be taxed as a real estate investment trust    
under the Internal Revenue Code of 1986.

THE MERGER

 WE ENCOURAGE YOU TO READ THE ENTIRE MERGER AGREEMENT WHICH IS ATTACHED AS
ANNEX A TO THIS JOINT PROXY STATEMENT AND PROSPECTUS.                           

    MERGER CONSIDERATION.  In the merger, each outstanding common share of Weeks
will be converted into the right to receive 1.38 common shares of Duke; each    
outstanding 8.0% Series A cumulative redeemable preferred share of Weeks will be
converted into the right to receive one preference share of Duke representing   
1/1,000 of an 8.0% Series F cumulative redeemable preferred share of Duke having
substantially identical rights and preferences; and each outstanding 8.625%     
Series D cumulative redeemable preferred share of Weeks will be converted into  
the right to receive one preference share of Duke representing 1/1,000 of an    
8.625% Series H cumulative redeemable preferred share of Duke having            
substantially identical rights and preferences. As of the date of this joint    
proxy statement and prospectus, there were no 8.625% Series H cumulative        
redeemable preferred shares of Weeks outstanding.                               

 No fractional shares will be issued in the merger. Cash will be issued in
lieu of fractional Duke common shares upon surrender of a Weeks share           
certificate and to satisfy any dividends or other cash distributions to which a 
shareholder is entitled, in each case without interest and less any required    
withholding taxes.                                                              

At least one business day prior to the merger of Weeks into Duke, Weeks'
principal operating subsidiary, Weeks Realty, L.P. (the "Weeks OP"), will be    
merged with and into Duke's principal operating subsidiary, Duke Realty Limited 
Partnership (the "Duke OP"). In the OP merger, each common unit of limited      
partnership interest in Weeks OP will be converted into 1.38 common units of    
limited partnership interest in Duke OP; each 8.0% Series A cumulative          
redeemable preferred unit in Weeks OP will be converted into one 8.0% Series F  
cumulative redeemable preferred unit in Duke OP; each 8.0% Series C cumulative  
redeemable preferred unit in Weeks OP will be converted into one 8.0% Series G  
cumulative redeemable preferred unit in Duke OP; and each 8.625% Series D       
cumulative redeemable preferred unit in Weeks OP will be converted into one     
8.625% Series H cumulative redeemable preferred unit in Duke OP.                

OWNERSHIP OF DUKE-WEEKS AFTER THE MERGER.  Duke will issue approximately
27.3 million common shares to Weeks common shareholders in the merger. Duke OP  
will issue approximately 10.1 million units of common limited partnership       
interest to the limited partners of Weeks OP in the OP merger. Each Duke OP     
common unit will be exchangeable by the holders of the units for one Duke common
share or, if Duke elects under certain circumstances, the cash value of one Duke
common share. The common shares that Duke will issue in the merger, plus the    
common shares Duke will reserve for issuance upon exchange of the Duke common OP
units issued in the OP merger, will represent 27.7% of the Duke-Weeks common    
shares that will be outstanding after the merger or potentially issuable upon   
exchange of outstanding Duke-Weeks common OP units. This information is based on
the number of shares of Duke and Weeks and the number of common units of Duke OP
and Weeks OP outstanding on March 1, 1999 and does not take into account shares 
issuable upon the exercise of outstanding stock options and warrants.           

EFFECTIVE TIME OF THE MERGER.  We currently expect the merger to become 
effective on June 30, 1999, or as soon as practicable thereafter, if the        
conditions to the merger are satisfied or waived.                               

CONDITIONS TO THE MERGER (SEE PAGE 57).  The completion of the merger   
depends upon meeting or waiving a number of conditions, including:              

- approval of the merger by the shareholders of Duke and Weeks;         

   - approval for listing on the New York Stock Exchange of Duke common shares
and Duke preference shares issuable in the merger;

- receipt of satisfactory legal opinions regarding Weeks' and Duke's    
 respective real estate investment trust status for federal income tax
     purposes and the treatment of the merger as a tax-free reorganization for
federal income tax purposes;                                        

  - no material adverse changes from the period between the execution of the
merger agreement and the closing date of the merger; and            

  - continued accuracy of the respective representations and warranties made
by Duke and Weeks in the merger agreement.                          

OFFICERS AND DIRECTORS OF DUKE-WEEKS AFTER THE MERGER (SEE PAGE 22).  If
Duke obtains the requisite vote of its shareholders to increase the maximum size
of Duke's Board of Directors to 23, then the Board of Directors of Duke-Weeks   
immediately following the merger will consist of 11 of the 12 current members of
Duke's Board and 10 of the 11 current members of Weeks' Board.                  

  If Duke does not obtain the requisite vote of its shareholders to increase
the size of its Board, then the Board of Directors of Duke-Weeks immediately    
following the merger will consist of 15 members, of which eight currently are   
members of Duke's Board and seven currently are members of Weeks' Board.        

Following the merger, Thomas L. Hefner, Duke's current chief executive  
officer, will be the chief executive officer of Duke-Weeks and A. Ray Weeks,    
Jr., Weeks' current chief executive officer, will be the president and chief    
operating officer of Duke-Weeks. See page 23 for a list of the other members of 
the senior management of Duke-Weeks.                                            

INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER (SEE PAGE 49).  When  
considering the Weeks Board's recommendation that Weeks' shareholders vote in   
favor of the merger, you should be aware that a number of Weeks' officers have  
stock options, employment and other agreements, retention incentives and other  
benefits plans, and that Weeks' directors that become Duke-Weeks directors      
pursuant to the merger will have rights to stock grants and stock options under 
Duke plans, in each case, that provide them with interests in the merger that   
are different from, or in addition to, yours.                                   

 TERMINATION (SEE PAGE 63).  Duke and Weeks can jointly agree to terminate
the merger agreement at any time, even if the shareholders of both companies    
have approved the merger. Also, either Duke or Weeks can decide, without the    
consent of the other, to terminate the merger agreement if:                     

- any judgment, injunction, order, decree or action by any governmental 
      entity of competent authority preventing the consummation of the merger or
the OP merger has become final and nonappealable;                   

- the required approval of the shareholders of either party has not been
obtained at the applicable shareholders meeting;                    

- the merger has not been consummated by December 31, 1999; or          

- the other party materially breaches the merger agreement.             

Weeks also may unilaterally terminate the merger agreement if:          

- the Board of Directors of Weeks withdraws or modifies its approval or 
recommendation of the merger or the OP merger in connection with a  
superior competing transaction (but this termination right can be   
     exercised by Weeks only before its shareholders meeting and not less than
30 days after its Board takes one of these actions); or             

  - (1) the Board of Directors of Duke withdraws or modifies its approval or
recommendation of the merger or the OP merger in connection with a  
superior competing transaction, (2) Duke or Duke OP enters into any 
    agreement with respect to any competing transaction, or (3) the Board of
Directors of Duke resolves to do any of those things.

  TERMINATION FEES (SEE PAGE 65).  Either Duke or Weeks may become liable to
the other for payment of a $50 million termination fee or expenses of up to $5  
million if the merger agreement is terminated.                                  

    OPINIONS OF FINANCIAL ADVISORS (SEE PAGES 36 AND 44).  On February 28, 1999,
Merrill Lynch, Pierce, Fenner & Smith Incorporated delivered its written opinion
to the Duke Board of Directors stating that, as of that date, the exchange ratio
pursuant to the merger agreement was fair, from a financial point of view, to   
Duke. The opinion of Merrill Lynch does not constitute a recommendation as to   
how any Duke shareholder should vote with respect to the merger. On February 28,
1999, Goldman, Sachs & Co. delivered its oral opinion to the Board of Directors 
of Weeks that, as of that date, the exchange ratio pursuant to the merger       
agreement was fair from a financial point of view to the holders of the         
outstanding Weeks common shares. Goldman Sachs confirmed its oral opinion by    
delivery of its written opinion dated February 28, 1999. The opinion of Goldman 
Sachs does not constitute a recommendation as to how any Weeks shareholder      
should vote with respect to the merger. These opinions, which are based upon and
subject to various qualifications and assumptions, are attached as Annexes B and
C to this joint proxy statement and prospectus. We encourage you to read these  
opinions in their entirety. The analyses performed by Merrill Lynch and Goldman 
Sachs are summarized in this joint proxy statement and prospectus under the     
captions "The Merger and the Merger Proposal--Opinion of Duke's Financial       
Advisor" and "--Opinion of Weeks' Financial Advisor."                           

APPRAISAL RIGHTS.  No dissenters' or appraisal rights are available with
respect to the merger.                                                          

REGULATORY APPROVALS.  The parties are not aware of any federal or state
regulatory approvals which must be obtained in connection with the merger and   
related transactions.                                                           

AMENDMENTS TO DUKE CHARTER AND DUKE BYLAWS

  The merger agreement provides that, as part of the merger, Duke's Articles
of Incorporation will be amended to change Duke's name to Duke-Weeks Realty     
Corporation for a two-year period following the effective time of the merger and
then to Duke Realty Corporation following that two year period (unless the      
combined company's Board of Directors recommends against changing the name) and 
to increase the common shares that Duke is authorized to issue from 150,000,000 
to 250,000,000. In addition, Duke's Board recommends that its shareholders vote 
to approve additional amendments to Duke's Articles of Incorporation (the       
"additional charter amendments"), including the following:                      

- increase the maximum number of directors from 15 to 23;               

    - change the existing requirement that 80% of the shares of CAPITAL STOCK of
  Duke approve certain amendments to Duke's Articles of Incorporation to
require the approval of 80% of the COMMON SHARES; and               

    - change the existing requirement that 80% of the shares of capital stock of
  Duke approve the number, classes, term of office and qualifications of
    directors, to require the approval of a majority of the common shares of
Duke.

Approval of the additional charter amendments is not a condition to the 
merger.                                                                         

At the effective time of the merger, if the first additional charter    
amendment described above is approved, Duke's Bylaws will be amended to increase
the size of Duke's Board to 23. If this additional charter amendment is not     
approved, the size of Duke's Board will remain at 15.                           

VOTING AGREEMENTS 

At the same time the merger agreement was signed,                       

- holders of approximately 2% of the outstanding Weeks common shares and
      holders of approximately 56% of the outstanding common limited partnership
   interests in Weeks OP (other than those held indirectly by Weeks, which
  are not entitled to vote) entered into voting agreements with Duke and
 Duke OP in which the holders granted Duke irrevocable proxies to vote
     their shares and partnership interests in favor of the merger, the merger
     agreement and the other transactions contemplated thereby and against any
competing proposal; and                                             

- holders of approximately 5% of the outstanding Duke common shares and 
      holders of approximately 95% of the outstanding common limited partnership
    interests in Duke OP entered into voting agreements with Weeks and Weeks
   OP in which the holders granted Weeks irrevocable proxies to vote their
shares and partnership interests in favor of the merger, the merger 
     agreement and the other transactions contemplated thereby and against any
competing proposal.                                                 

   As a result of these arrangements, the approvals by the partners of Duke OP
and Weeks OP that are required for the OP merger have already been obtained.

SELECTED FINANCIAL DATA 

SELECTED HISTORICAL FINANCIAL DATA OF DUKE                                      

  We are providing the following financial information of Duke to aid you in
your analysis of the financial aspects of the merger. We derived this           
information from audited consolidated financial statements for the years ended  
December 31, 1994 through 1998. The amounts are stated in thousands, except for 
the per share data. Information with respect to per share data for all five     
years reflects the two-for-one stock split effected in August 1997. Funds from  
Operations presented below is defined by the National Association of Real Estate
Investment Trusts as net income or loss excluding gains or losses from debt     
restructuring and sales of property plus depreciation and amortization, and     
after adjustments for minority interests and unconsolidated companies           
(adjustments for minority interests and unconsolidated companies are calculated 
to reflect Funds from Operations on the same basis). Funds from Operations does 
not represent cash flow from operations as defined by generally accepted        
accounting principles, should not be considered as an alternative to net income 
as an indicator of operating performance, and is not indicative of cash         
available to fund all cash flow needs. This information is only a summary and   
you should read it together with Duke's historical consolidated financial       
statements, and related notes, contained in the annual reports and other        
information that Duke files with the Securities and Exchange Commission. See    
"Where You Can Find More Information" on page 94.

DUKE-WEEKS PRO FORMA SUMMARY FINANCIAL DATA 

 We expect that the merger will be accounted for as a purchase. For a more
detailed description of purchase accounting, see "The Merger and the Merger     
Proposal--Accounting Treatment" on page 54.                                     

We have presented below unaudited pro forma financial information that  
reflects the purchase method of accounting and is intended to give you a better 
picture of what our businesses might have looked like had the merger occurred on
January 1, 1998, with respect to operating data, and December 31, 1998, with    
respect to balance sheet data. The pro forma financial information does not     
purport to represent what the combined company's results of operations would    
have been for the year ended December 31, 1998 if the merger had in fact        
occurred on January 1, 1998. The amounts are stated in thousands, except for the
per share data. We prepared the pro forma condensed consolidated balance sheet  
by making adjustments to reflect the assets and liabilities acquired at their   
fair value and made other merger-related adjustments. We prepared the pro forma 
condensed consolidated statements of operations by combining the historical     
amount of earnings of each company. We then adjusted the combined amount to     
reflect differences in the operating results that would have resulted if the    
merger had occurred on January 1, 1998. The companies may have performed        
differently if they had been combined. You should not rely on the pro forma     
financial information as being indicative of the historical results that we     
would have had or the future results that we will experience after the merger.  

The information is only a summary and you should read it together with  
Duke's and Weeks' historical financial statements incorporated in this joint    
proxy statement and prospectus, and the Duke-Weeks pro forma condensed          
consolidated financial statements included in this joint proxy statement and    
prospectus beginning on page F-1.

COMPARATIVE MARKET AND PER SHARE DATA 

We have summarized below the per share information for our respective   
companies on an historical basis, combined pro forma basis and combined         
equivalent pro forma basis. The combined pro forma summary amounts are based on 
the purchase method of accounting. The Weeks per share combined pro forma       
equivalents are calculated by multiplying the combined pro forma per share      
amounts by 1.38. Weeks shareholders will receive 1.38 Duke common shares in     
exchange for each Weeks common share. The following information should be read  
together with the historical and pro forma financial statements included or     
incorporated by reference in this joint proxy statement and prospectus.         

   On February 26, 1999, the last trading day prior to the announcement of the
signing of the merger agreement, the closing price of a Duke common share was   
$21.8125. On the same day, the closing price of a Weeks common share was $27.00.
The equivalent per share value of a Weeks common share on that date, applying   
the exchange ratio per share, was $30.10125.

RISK FACTORS

   YOU SHOULD CONSIDER CAREFULLY THE FACTORS SET FORTH BELOW IN EVALUATING THE
MERGER. THE FOLLOWING LIST SUMMARIZES ALL MATERIAL RISKS RELATED TO THE MERGER. 
THIS JOINT PROXY STATEMENT AND PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS   
WITH RESPECT TO THE OPERATIONS OF DUKE, WEEKS AND THE COMBINED COMPANY. ACTUAL  
RESULTS COULD DIFFER MATERIALLY FROM THOSE SET FORTH IN THE FORWARD-LOOKING     
STATEMENTS. SEE "CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS"     
(PAGE 19).                                                                      

RISK FACTORS RELATING TO THE MERGER 

FIXED MERGER CONSIDERATION MAY NOT REFLECT CHANGES IN SHARE VALUE.              

The value of Duke common shares and Weeks common shares at the effective
time of the merger may be different from the price and value of these securities
on the date the merger consideration was determined. This difference could be   
caused by changes in the operations and prospects of Duke or Weeks, general     
market and economic conditions or other factors which are beyond the control of 
either party.                                                                   

THE FAIRNESS OPINIONS OBTAINED BY DUKE AND WEEKS WILL NOT REFLECT CHANGES IN THE
RELATIVE VALUES OF THE COMPANIES SINCE THE MERGER AGREEMENT WAS SIGNED.         

    Duke does not intend to obtain an updated fairness opinion of Merrill Lynch,
Pierce, Fenner & Smith Incorporated, and Weeks does not intend to obtain an     
updated fairness opinion of Goldman, Sachs & Co. Changes in the operations and  
prospects of Duke or Weeks, general market and economic conditions and other    
factors which are beyond the control of Duke or Weeks, on which the opinions of 
Merrill Lynch and Goldman Sachs are based, may have altered the relative value  
of the companies. Therefore, the opinions of Merrill Lynch and Goldman Sachs do 
not address the fairness of the merger consideration at the time the merger will
be completed.                                                                   

THE MERGER WILL EXPOSE THE COMBINED COMPANY TO THE GENERAL ECONOMIC CONDITIONS  
OF SEVERAL NEW MARKETS IN WHICH EITHER DUKE OR WEEKS WERE NOT PREVIOUSLY        
INVOLVED.                                                                       

   The combined company's operating performance could be adversely affected if
conditions, such as an oversupply of space or a reduction in demand for         
industrial, office or retail properties, in the combined company's larger       
markets, principally the Atlanta, Cincinnati, Indianapolis and St. Louis        
markets, become less favorable relative to other geographic areas. Any material 
oversupply of space or material reduction of demand for space could adversely   
affect the combined company's operating income and the value of the combined    
company's shares.                                                               

THE EXPECTATION THAT THE MERGER WILL RESULT IN AN EFFICIENT INTEGRATION OF THE  
COMPANIES MAY NOT BE REALIZED.                                                  

  Weeks and Duke have entered into the merger agreement with the expectation
that the merger will create a combined company which will be able to operate    
efficiently in Midwestern and Sunbelt markets. Achieving this anticipated result
will depend in part on the efficient integration of the businesses of Weeks and 
Duke, each of which is a large organization. There can be no assurance that an  
efficient integration will occur. For a discussion of other factors and         
assumptions related to the anticipated benefits of the merger, see "The Merger  
and the Merger Proposal--Reasons for the Merger; Recommendation of the Duke     
Board" and "--Reasons for the Merger; Recommendation of the Weeks Board."       

THE COMPANIES HAVE EXPENDED RESOURCES AND CAPITAL IN THE PURSUIT OF THIS MERGER,
AND IF THE MERGER FAILS TO OCCUR, THE COMPANIES WILL NOT BENEFIT FROM THESE     
EXPENDITURES AND MAY INCUR ADDITIONAL PAYMENTS.                                 

 The merger may not be completed. If the merger is not completed, Duke and
Weeks will have incurred substantial expenses for which no ultimate benefit will
have been received by either company. Additionally, if the merger agreement is  
terminated, Duke may be required to pay Weeks a $50 million termination fee or  
reimburse up to $5 million of termination expenses or Weeks may be required to  
pay

Duke a $50 million termination fee or reimburse up to $5 million of termination 
expenses. See "The Merger Agreement--Termination."                              

THE DIRECTORS AND OFFICERS OF WEEKS MAY HAVE INTERESTS IN THE COMPLETION OF THE 
MERGER THAT ARE DIFFERENT FROM THE INTEREST OF WEEKS SHAREHOLDERS.              

The following officers of Weeks have entered into change of control     
agreements with Weeks which entitle the officers rights to receive, upon a      
change of control, severance payments upon involuntary termination of their     
employment: A. Ray Weeks, Jr., Thomas D. Senkbeil, Forrest W. Robinson, David P.
Stockert, John W. Nelley, Jr., Robert G. Cutlip, Clyde H. Duckett, Mark W.      
Flowers, Charles D. Graham, Eben Hardie III and Jeffrey D. Turner. In addition, 
the change of control agreements entered into with each of Messrs. Weeks,       
Senkbeil, Robinson, Stockert and Nelley entitle these officers to receive the   
severance benefit if they voluntarily terminate their employment before the     
first anniversary of the change of control. Each of these officers has agreed   
with Duke to waive their right to the severance benefit if they voluntarily     
terminate their employment after the merger, except that Mr. Stockert will be   
entitled to receive the severance benefit provided for in his change of control 
agreement if he voluntarily terminates his employment during the four month     
period beginning on the first anniversary of the effective time of the merger.  
In order to induce Mr. Robinson to modify his rights under his change of control
agreement, Duke agreed to provide him with a $250,000 unsecured loan payable in 
equal annual installments over a five year term in order to facilitate his      
relocation to Florida. The terms of the loan provide that (1) annual payments of
principal will be forgiven so long as Mr. Robinson is still employed by         
Duke-Weeks and (2) the principal and interest will be forgiven in full if (A)   
Mr. Robinson is terminated other than for cause by Duke-Weeks, (B) Mr. Robinson 
terminates his own employment for good reason within the 12 month period        
following the effective time of the merger, or (C) Duke changes the terms of the
agreement made with Mr. Robinson regarding modification of his rights under his 
change of control agreement without his prior consent before the first          
anniversary of the merger.                                                      

    At the time of the execution and delivery of the merger agreement, a company
owned by Thomas L. Hefner, Darrell E. Zink, Jr., A. Ray Weeks, Jr. and Thomas D.
Senkbeil was granted options to purchase interests in three service companies   
owned by certain current and former Weeks officers, including A. Ray Weeks, Jr.,
Thomas D. Senkbeil and Forrest W. Robinson. If the company exercises these      
options, the aggregate payment received by these current and former Weeks       
officers would be approximately $130,000.                                       

  Weeks directors who become directors of Duke-Weeks will be compensated for
their services as directors and granted stock options annually during their     
tenure as directors. Non-employee directors of Duke-Weeks are entitled to       
receive 300 common shares of Duke pursuant to Duke's 1996 Directors' Stock      
Payment Plan for each full calendar quarter of service as a Director (or a      
pro-rata amount for less than a full calendar quarter of service). In addition, 
if Duke's 1999 Directors' Stock Option and Dividend Increase Unit Plan is       
approved by the shareholders of Duke, directors of Duke-Weeks who are not       
entitled to receive grants of options under any other Duke sponsored plan for   
any given year will be granted options to purchase 2,500 common shares of Duke  
for that year. Weeks directors who become Duke-Weeks directors will first       
receive such stock option grants at the first quarterly meeting of Duke-Weeks'  
compensation committee for the year 2000. These persons will receive benefits   
that will not be shared by other shareholders of Weeks generally.               

THE RIGHTS OF DUKE SHAREHOLDERS DIFFER FROM THOSE OF WEEKS.                     

 The rights of shareholders of Weeks currently are governed by Georgia law
applicable to corporations formed under the laws of that state and by Weeks'    
articles of incorporation and bylaws. Upon completion of the merger,            
shareholders of Weeks will become shareholders of Duke-Weeks and their rights   
will be governed by Indiana law applicable to corporations formed under the laws
of that state and by Duke's charter and by-laws. The rights of shareholders of  
Weeks differ materially from the rights of shareholders

of Duke and the rights of the former Weeks shareholders in Duke may be less     
favorable than their former rights as shareholders of Weeks. See "Comparison of 
Shareholder Rights."                                                            

RISK FACTORS RELATING TO THE OWNERSHIP OF REAL ESTATE SECURITIES

THE COMBINED COMPANY'S REAL ESTATE INVESTMENTS ARE SUBJECT TO RISKS PARTICULAR  
TO REAL ESTATE INVESTMENTS.                                                     

Real property investments are subject to varying degrees of risk. Real  
estate values are affected by a number of factors, including:                   

- changes in general economic conditions;                               

   - local conditions, such as an oversupply of space or a reduction in demand
for real estate in an area;                                         

- competition from other available space;                               

 - the ability of the owner to provide adequate maintenance and insurance;

- the ability of the owner to control variable operating costs;         

- government regulations;                                               

- interest rate levels;                                                 

- the availability of financing; and                                    

- potential liability under, and changes in, environmental, zoning, and 
other laws.                                                         

THE COMBINED COMPANY'S REAL ESTATE DEVELOPMENT ACTIVITIES ARE SUBJECT TO RISKS  
PARTICULAR TO DEVELOPMENT.                                                      

    The combined company intends to continue to pursue development activities as
opportunities arise. These development activities generally require various     
government and other approvals. The combined company may not receive the        
necessary approvals.                                                            

The combined company will be subject to risks associated with any       
development activities. These risks include:                                    

- development opportunities explored by the combined company may be     
abandoned;                                                          

 - construction costs of a project may exceed original estimates, possibly
making the project less profitable than originally estimated;       

 - the time required to complete construction of a project or to lease out
     the completed project may be greater than originally anticipated, thereby
   adversely affecting the combined company's cash flow and liquidity; and

   - occupancy rates and rents of a completed project may not be sufficient to
make the project profitable.                                        

In the case of an unsuccessful development project, the combined company
could lose its investment in the project.                                       

THE COMBINED COMPANY IS EXPOSED TO THE RISKS OF DEFAULTS BY TENANTS.            

    The combined company's income and distributable cash flow would be adversely
affected if a significant number of the combined company's tenants were unable  
to meet their obligations to the combined company, especially if the combined   
company were unable to lease to another party, on economically favorable terms, 
a significant amount of space vacated by tenants in its properties. In the event
of default by a significant number of tenants, the combined company may         
experience delays in collecting rent and incur substantial costs in enforcing   
its rights as landlord.

REAL ESTATE INVESTMENTS ARE RELATIVELY ILLIQUID GENERALLY, AND DUKE HAS AGREED  
TO ASSUME ADDITIONAL RESTRICTIONS ON PROPERTY SALES IN THE MERGER AGREEMENT.    

Equity real estate investments are relatively illiquid and therefore may
tend to limit the ability of the combined company to react promptly to changes  
in economic or other conditions. In addition, significant expenditures          
associated with equity real estate investments, such as mortgage payments, real 
estate taxes and maintenance costs, are generally not reduced when circumstances
cause a reduction in income from the investments. Like other companies          
qualifying as real estate investment trusts under the Internal Revenue Code of  
1986, the combined company will be subject to a 100% penalty tax on gain        
recognized from the sale of property held for sale to customers in the ordinary 
course of business or other "dealer" property. To ensure that real property     
sales are not viewed as "dealer" property, the combined company may comply with 
certain safe harbor rules relating to the number of properties sold in a year,  
their tax bases and the cost of improvements made to these properties.          

In the merger agreement, Duke agreed to assume four agreements of Weeks 
which restricted Weeks' ability to sell certain of its properties. Duke is also 
currently party to four agreements which restrict Duke's ability to sell certain
of its properties. Duke also agreed that until the tenth anniversary of the     
effective time of the merger, any proposed sale or a series of related sales by 
the combined company of assets which were previously owned by Weeks and have a  
value of more than $50 million must first be approved by the asset committee of 
the combined company's Board of Directors. Compliance with the foregoing safe   
harbor rules and these agreements may restrict the combined company's ability to
sell assets at any time to change its asset base.                               

THE COMBINED COMPANY IS EXPOSED TO POTENTIAL ENVIRONMENTAL LIABILITY.           

  Under various federal, state and local laws, ordinances and regulations, a
current or previous owner, developer or operator of real estate may be liable   
for the costs of removal or remediation of hazardous or toxic substances at, on,
under or in its property. The costs of removal or remediation of hazardous or   
toxic substances could be substantial. Environmental laws often impose liability
without regard to whether the owner or operator knew of, or was responsible for,
the release or presence of hazardous substances. The presence of hazardous      
substances on the combined company's properties may adversely affect its ability
to sell those properties or to borrow using those properties as collateral and  
may also have an adverse effect on the combined company's ability to pay        
distributions to its shareholders.                                              

THE COMBINED COMPANY COULD INCREASE ITS LEVEL OF DEBT IN SUCH A MANNER THAT     
COULD JEOPARDIZE CASH DISTRIBUTIONS TO SHAREHOLDERS.                            

Each of Duke and Weeks currently has a policy of incurring debt only if,
upon such incurrence, the combined company's debt-to-total market capitalization
ratio, as adjusted, would equal 50% or less. The combined company's Board of    
Directors could alter or eliminate this policy without shareholder approval and 
would do so if, for example, it were necessary in order for the combined company
to continue to qualify as a real estate investment trust under the Internal     
Revenue Code of 1986. If this policy were changed, the combined company could   
become more highly leveraged, resulting in an increase in debt service that     
could adversely affect the cash available for distribution to shareholders. The 
combined company's pro forma debt-to-total market capitalization ratio at       
December 31, 1998 was approximately 31%.                                        

THE FAILURE OF THE COMBINED COMPANY TO QUALIFY AS A REAL ESTATE INVESTMENT TRUST
COULD ADVERSELY AFFECT SHAREHOLDERS.                                            

Duke has elected to be taxed as a real estate investment trust under the
Internal Revenue Code of 1986 commencing with its taxable year ended December   
31, 1986. The combined company will inherit this tax status. To maintain real   
estate investment trust status, the combined company must meet a number of      
highly technical requirements on a continuing basis. These requirements seek to 
ensure, among other

things, that the gross income and investments of a real estate investment trust 
are largely real estate related, that a real estate investment trust distributes
substantially all its ordinary taxable income to shareholders on a current basis
and that the real estate investment trust's share ownership is not overly       
concentrated in the hands of individuals (including certain entities treated as 
individuals). Due to the complex nature of these rules, the limited available   
guidance concerning interpretation of the rules, the importance of ongoing      
factual determinations and the possibility of adverse changes in the law,       
administrative interpretations of the law and developments at the combined      
company, no assurance can be given that the combined company will qualify as a  
real estate investment trust for any particular year.                           

   If the combined company fails to qualify as a real estate investment trust,
it will be taxed as a regular corporation, and distributions to shareholders    
will not be deductible in computing the combined company's taxable income. The  
resulting corporate tax liabilities could materially reduce the funds available 
for distribution to the combined company's shareholders or for reinvestment. In 
the absence of real estate investment trust status, distributions to            
shareholders would no longer be required. Moreover, the combined company might  
not be able to elect to be treated as a real estate investment trust for the    
four taxable years after the year during which the combined company ceased to   
qualify as a real estate investment trust. In addition, if the combined company 
later requalified as a real estate investment trust, it might be required to pay
a full corporate-level tax on any unrealized gain in its assets as of the date  
of requalification and to make distributions to shareholders equal to any       
earnings accumulated during the period of non-real estate investment trust      
status, all of which would materially reduce the funds available for            
distribution to the combined company's shareholders or for reinvestment.        

REAL ESTATE INVESTMENT TRUST DISTRIBUTION REQUIREMENTS LIMIT THE AMOUNT OF CASH 
THE COMBINED COMPANY WILL HAVE AVAILABLE FOR OTHER BUSINESS PURPOSES, INCLUDING 
AMOUNTS TO FUND THE COMBINED COMPANY'S FUTURE GROWTH.                           

 To maintain its qualification as a real estate investment trust under the
Internal Revenue Code of 1986, the combined company must annually distribute to 
the combined company's shareholders at least 95% of its ordinary taxable income,
excluding net capital gains. This requirement limits the combined company's     
ability to accumulate capital for use for other business purposes. If the       
combined company does not have sufficient cash or other liquid assets to meet   
the distribution requirements, the combined company may have to borrow funds or 
sell properties on adverse terms in order to meet the distribution requirements.
If the combined company fails to make a required distribution, it would cease to
qualify as a real estate investment trust.

THE COMPANIES 

DUKE                                                                            

 Duke is a self-administered and self-managed REIT organized under Indiana
law. Duke owns and leases industrial, office and retail properties throughout   
the Midwest which it and its predecessors have been doing since 1972. As of     
December 31, 1998, Duke owned interests in a diversified portfolio of 493 rental
properties comprising approximately 59.3 million square feet (including 40      
buildings and three expansions comprising approximately 7.2 million square feet 
under development). Substantially all of these properties are located in        
Indianapolis, Indiana; Cincinnati, Cleveland, and Columbus, Ohio; St. Louis,    
Missouri; Minneapolis, Minnesota; Chicago, Illinois; and Nashville, Tennessee.  
Also, as of December 31, 1998, Duke owned or controlled approximately 2,800     
acres of unencumbered land, which Duke believes could support the development of
approximately 43 million square feet of properties. In addition to its rental   
operations, Duke, through its service operations provides leasing, management,  
construction, development and other real estate services for approximately 6.9  
million square feet of properties owned by third parties. Duke's rental         
operations are conducted through Duke Realty Limited Partnership. In addition,  
Duke conducts its service operations through Duke Realty Services Limited       
Partnership and Duke Construction Limited Partnership, in which the company's   
wholly-owned subsidiary, Duke Services, Inc., is the sole general partner. Duke 
has the largest commercial real estate operations in Indianapolis and Cincinnati
and is one of the largest real estate companies in the Midwest.                 

Duke's headquarters and executive offices are located in Indianapolis,  
Indiana. In addition, Duke has seven regional offices located in Cincinnati,    
Ohio; Columbus, Ohio; Cleveland, Ohio; Chicago, Illinois; Nashville, Tennessee; 
St. Louis, Missouri and Minneapolis, Minnesota. Duke had 748 employees as of    
December 31, 1998.                                                              

 As a fully integrated commercial real estate firm, Duke believes that its
in-house leasing, management, development and construction services and Duke's  
significant base of commercially zoned and unencumbered land in existing        
business parks should give Duke a competitive advantage in its future           
development activities.                                                         

    Duke has sought to develop and acquire Class A commercial properties located
in markets with high growth potential for Fortune 500 companies and other       
quality regional and local firms. Duke's industrial and suburban office         
development has focused on business parks and mixed-use developments suitable   
for development of multiple projects on a single site where Duke can create and 
control the business environment. These business parks and mixed-use            
developments generally include restaurants and other amenities which Duke       
believes create an atmosphere that is particularly efficient and desirable.     
Duke's retail development has focused on community, power and neighborhood      
centers in its existing markets. As a fully integrated real estate company, Duke
has been able to arrange for or provide to its industrial, office and retail    
tenants not only well located and well maintained facilities, but also          
additional services such as build-to-suit construction, tenant finish           
construction, expansion flexibility and advertising and marketing services.     

WEEKS                                                                           

Weeks is a self-administered and self-managed REIT that was organized in
1994 under Georgia law to continue and expand the fully integrated real estate  
business previously conducted by Weeks and its affiliates. Since 1965, Weeks,   
together with its affiliates and predecessors, has developed, owned, managed,   
constructed and acquired primarily institutional-quality industrial and suburban
office properties in select suburban markets in the southeast United States and 
Texas. As of December 31, 1998, Weeks owned 371 properties totaling             
approximately 31.6 million square feet, including 52 properties that were under 
development or in lease-up and excluding two properties that were under         
agreement to acquire. Weeks' properties are located in Atlanta, Georgia;        
Nashville, Tennessee; Raleigh-Durham-Chapel Hill, North

Carolina; Miami, Orlando, Jacksonville, Ft. Landerdale and Tampa, Florida;      
Dallas, Texas; and Spartanburg, South Carolina.                                 

   At December 31, 1998, Weeks also owned or controlled (through agreements to
acquire, options and marketing and development agreements) approximately 1,900  
net usable acres of undeveloped land located primarily in existing business     
parks with zoning and infrastructure in place. Weeks believes the development   
potential of this land could ultimately total approximately 20 million square   
feet (based upon Weeks' estimate of the appropriate density and anticipated     
building types that may be developed, net of land necessary to provide for      
adequate infrastructure).                                                       

    Weeks conducts its third-party service business through two companies: Weeks
Realty Services, Inc., which conducts third-party landscape, property management
and leasing services, and Weeks Construction Services, Inc., which conducts     
third-party construction services. Weeks holds 100% of the nonvoting and 1% of  
the voting common shares of these subsidiaries. The remaining voting common     
shares are held by three executive officers of Weeks. The ownership of the      
common shares of these companies entitles Weeks to substantially all (99%) of   
the economic benefits from the results of their operations. As described under  
"The Merger and the Merger Proposal--Service Companies Option," three executive 
officers of Weeks have granted an option to purchase all of their shares in     
these two companies to a newly formed corporation owned by Messrs. Hefner, Zink,
Weeks and Senkbeil.                                                             

  Weeks owns, develops and operates primarily industrial and suburban office
properties, most of which are located in landscaped business park settings.     
Weeks' business strategy emphasizes high quality properties and tenant service. 
Weeks' approximately 575 employees have experience and are engaged in virtually 
every aspect of the real estate business, including development, construction,  
engineering, design, landscape, leasing, marketing and property management.     
Weeks' strategy for growth includes intensive management of its properties,     
developing and acquiring additional properties that are consistent with its     
existing portfolio, and owning and controlling undeveloped land sufficient to   
develop new and existing business parks and to meet the expansion and relocation
needs of its tenants. Weeks concentrates its activities in a limited number of  
Sunbelt cities where it believes it can sustain a significant market presence.  

THE COMBINED COMPANY                                                            

 Upon completion of the merger, Duke-Weeks is expected to have a total pro
forma market capitalization of approximately $5.2 billion, based on the closing 
price of Duke shares on February 26, 1999 (the last full trading day before the 
merger was announced) and the outstanding principal amount of indebtedness of   
the two companies on December 31, 1998. The combined company will own interests 
in 864 industrial, office and retail properties (including properties under     
development), based on the real estate assets held by Duke and Weeks as of      
December 31, 1998. The combined real estate assets, including assets held by    
unconsolidated subsidiaries and joint ventures, will consist of over 90 million 
square feet of operating industrial, office and retail properties. Additionally,
the combined company will own or control approximately 4,700 acres of           
undeveloped land with an estimated future development potential of approximately
63 million square feet of industrial, office and retail properties. The name of 
the combined company for two years after the merger will be Duke-Weeks Realty   
Corporation and then Duke Realty Corporation after that two year period, unless 
the combined company's Board of Directors recommends against changing the name. 
The combined company intends to continue to be taxed as a real estate investment
trust under the Internal Revenue Code of 1986.                                  

  Duke and Weeks expect the combined company to have the following important
characteristics, which are intended to create long-term shareholder value:      

  - the combined company will be the largest mixed office/industrial REIT in
   the United States based on the amount of rentable space it will own and
equity market capitalization;                                       

21

 - the combined company expects to improve its valuation relative to other
   REITS in the public market because of greater liquidity of its publicly
     traded securities, increased research coverage, a more diversified credit
profile and an enhanced institutional shareholder base;             

- the combined company will have a strong combined management team      
     benefiting from the combined years of experience in the industrial/office
   real estate industry of Duke and Weeks and will be able to leverage its
      skills over a broader base of assets and a large development pipeline; and

- the combined company will have a more geographically diversified asset
   base which should reduce cash flow sensitivity to local economic cycles
and provide more consistent development opportunities.              

   Duke-Weeks' business objective is to increase its funds from operations by:

    - maintaining and increasing property occupancy and rental rates through the
      aggressive leasing and management of its portfolio of existing properties;

- expanding existing properties;                                        

- developing and acquiring new properties; and                          

- providing a full line of real estate services to its tenants and to   
third-parties.                                                      

  Duke-Weeks expects to utilize its approximately 4,700 acres of undeveloped
land and its many business relationships with nearly 5,000 commercial tenants to
expand its build-to-suit business (development projects substantially pre-leased
to a single tenant) and to pursue other development and acquisition             
opportunities in its primary markets and elsewhere.                             

Duke-Weeks seeks to maintain a well-balanced, conservative and flexible 
capital structure by:                                                           

- currently targeting a ratio of long-term debt to total market         
capitalization in the range of 25% to 40%;                          

- extending and sequencing the maturity dates of its debt;              

- borrowing primarily at fixed rates;                                   

- generally pursuing current and future long-term debt financings and   
refinancings on an unsecured basis; and                             

 - maintaining conservative debt service and fixed charge coverage ratios.

    Management believes that these strategies should enable Duke-Weeks to access
the debt and equity capital markets for its long-term capital requirements such 
as debt refinancings and financing development and acquisitions of additional   
rental properties.                                                              

  BOARD OF DIRECTORS AND MANAGEMENT OF DUKE-WEEKS AFTER THE MERGER.  If Duke
obtains the requisite vote of its shareholders to amend its Articles of         
Incorporation to increase the maximum size of Duke's Board to 23, then the Board
of Directors of Duke-Weeks immediately following the merger will consist of 11  
of the 12 current members of Duke's Board (Ms. Cuneo and Messrs. Baur, Button,  
Feinsand, Hefner, Lytle, Peterson, Rogers, Staton, Strauss and Zink) and 10 of  
the 11 current members of Weeks' Board (Messrs. Branch, Busbee, Cavanaugh,      
Codina, Eitel, McCoy, Nelley, Robinson, Senkbeil and Weeks).                    

  If Duke does not obtain the requisite vote of its shareholders to increase
the maximum size of its Board to 23, the Board of Directors of Duke-Weeks       
immediately following the merger will consist of 15 members of which eight are  
current members of Duke's Board (Ms. Cuneo and Messrs. Button, Feinsand, Hefner,
Lytle, Rogers, Strauss and Zink) and seven are current members of Weeks' Board  
(Messrs. Branch, Cavanaugh, Eitel, McCoy, Nelley, Senkbeil and Weeks).

meeting or any adjournment of the meeting.                              

DUKE                                                                            

 VOTING RIGHTS; VOTES REQUIRED FOR APPROVAL.  The Duke Board has fixed the
close of business on May 3, 1999, as the record date for the determination of   
the Duke shareholders entitled to notice of and to vote at the Duke meeting. On 
April 27, 1999, there were 86,751,130 Duke common shares and 15,400,000 Duke    
depositary shares, each representing 1/10 of a Duke preferred share,            
outstanding, which were held by approximately 8,868 and 94 record holders,      
respectively. As of April 27, 1999, Duke's directors and executive officers     
beneficially owned an aggregate of 4,373,168 Duke common shares (excluding      
shares subject to options), or approximately 5% of the outstanding Duke common  
shares entitled to vote on the merger proposal, which requires the affirmative  
vote of a majority of Duke's outstanding common shares. Directors and executive 
officers of Duke and entities which they control have agreed to vote all of     
their common shares, representing approximately 5% of Duke's outstanding common 
shares, in favor of the merger and the merger agreement and against any         
competing transaction. See "The Merger and the Merger Proposal--Voting          
Agreements."

   The presence, either in person or by proxy, of the holders of a majority of
the outstanding Duke common shares is necessary to constitute a quorum at the   
Duke meeting. Assuming the existence of a quorum, the affirmative vote of the   
holders of at least a majority of the issued and outstanding Duke common shares 
is required to approve the merger proposal, which includes amendments to Duke's 
Articles of Incorporation that would change Duke's name to Duke-Weeks Realty    
Corporation for two years after the merger and then to Duke Realty Corporation  
following that two year period (unless the combined company's Board of Directors
recommends against changing the name), and would increase the maximum number of 
common shares that Duke is authorized to issue from 150,000,000 to 250,000,000. 
Approval of the 1999 Directors' Stock Option and Dividend Increase Unit Plan,   
the 1999 Salary Replacement Stock Option and Dividend Increase Unit Plan and the
amendment to the 1996 Directors' Stock Payment Plan requires the affirmative    
vote of at least a majority of the votes cast by the holders of common shares at
the meeting. Approval of the additional charter amendments, including the       
charter amendment to increase the size of Duke's Board, requires the affirmative
vote of at least 80% of the outstanding Duke common and preferred shares, voting
together as a single class, and, in the case of the additional charter          
amendments which would (1) change the existing requirement that 80% of the      
shares of CAPITAL STOCK of Duke approve certain amendments to Duke's Articles of
Incorporation to require the approval of 80% of the Duke COMMON SHARES and (2)  
change the existing requirement that 80% of the shares of capital stock approve 
any amendment to the provisions of the Articles of Incorporation relating to the
number, classes, term of office and qualifications of directors, to require the 
approval of a majority of the Duke common shares, also requires the affirmative 
vote of at least two-thirds of the shares of each series of preferred shares    
outstanding. The election of three directors to Duke's Board requires the       
affirmative vote of at least a majority of the Duke common shares present in    
person or by proxy at the meeting. Holders of record of Duke common shares and  
preferred shares on the Duke record date are entitled to one vote per Duke      
common share at the Duke meeting. Holders of record of Duke depositary shares,  
each representing 1/10 of one Duke preferred share on the Duke record date are  
entitled to one vote per Duke depositary share at the Duke meeting.             

If a shareholder attends the Duke meeting, he or she may vote by ballot.
However, since many shareholders may be unable to attend the Duke meeting, those
shareholders can ensure that their shares are voted at the meeting by signing   
and dating the enclosed proxy and returning it in the envelope provided. When a 
proxy card is returned properly signed and dated, the Duke shares represented by
that proxy card will be voted in accordance with the instructions on the proxy  
card. For approval of the merger and the additional charter amendments, if a    
shareholder does not return a signed proxy card, their Duke shares will not be  
voted and thus will have the effect of a vote "against" the proposals.          
Similarly, a broker non-vote or an abstention will have the effect of a vote    
"against" the proposals. For the election of the nominees to the Duke Board of  
Directors and approval of the 1999 Directors' Stock Option and Dividend Increase
Unit Plan, the 1999 Salary Replacement Stock Option and Dividend Increase Unit  
Plan and the amendment to the 1996 Directors' Stock Payment Plan, broker        
non-votes and abstentions will not be counted as a vote for or against those    
proposals. Shareholders are urged to mark the box on the proxy card to indicate 
how their Duke shares are to be voted. If a shareholder returns a signed proxy  
card, but does not indicate how their Duke shares are to be voted, the Duke     
shares represented by the proxy card will be voted "FOR" the proposals. The     
proxy card also confers discretionary authority on the individuals appointed by 
the Duke Board and named on the proxy card to vote the Duke shares represented  
thereby on any other matter that is properly presented for action at the Duke   
meeting. Such discretionary authority will not be used to vote for adjournment  
of the Duke meeting to permit further solicitation of proxies if the shareholder
votes against any proposal.                                                     

 Any Duke shareholder who executes and returns a proxy card may revoke the
proxy at any time before it is voted by:                                        

(1) notifying in writing the Assistant Secretary of Duke at 8888
Keystone Crossing, Suite 1200, Indianapolis, Indiana 46240-2438;        

(2) granting a subsequent proxy; or

(3) appearing in person and voting at the Duke meeting.         

Attendance at the Duke meeting will not in and of itself constitute     
revocation of a proxy.                                                          

Duke has not yet selected its independent auditors for the fiscal year  
ending December 31, 1999. However, representatives of KPMG LLP, its independent 
auditors for the fiscal year ending December 31, 1998, are expected to be       
present at the annual meeting of shareholders of Duke with the opportunity to   
make a statement if they desire to do so, and will be available to respond to   
questions.                                                                      

 SOLICITATION OF PROXIES.  Duke will bear its own costs of solicitation of
proxies, except that the cost of preparing, printing and mailing this joint     
proxy statement and prospectus will be borne equally by Duke and Weeks.         
Brokerage houses, fiduciaries, nominees and others will, upon request, be       
reimbursed for their out-of-pocket expenses in forwarding proxy materials to    
owners of Duke common and preferred shares held in their names. In addition to  
the solicitation of proxies by use of the mails, proxies may be solicited from  
Duke shareholders by directors, officers and employees of Duke in person or by  
telephone, telegraph, facsimile or other appropriate means of communication. No 
additional compensation, except for reimbursement of reasonable out-of-pocket   
expenses, will be paid to these directors, officers and employees of Duke in    
connection with the solicitation. In addition, Innisfree M&A Incorporated, a    
proxy solicitation firm, has been engaged by Duke to act as proxy solicitor and 
will receive fees estimated at $15,000, plus reimbursement of out-of-pocket     
expenses. Any questions or requests for assistance regarding this joint proxy   
statement and prospectus and related proxy materials may be directed to the     
Investor Relations Department of Duke by telephone at (317) 808-6005.           

OTHER MATTERS                                                                   

    Duke is not aware of any business or matter other than those indicated above
which may be properly presented at the Duke meeting. If, however, any other     
matter properly comes before the Duke meeting, the proxy holders will, in their 
discretion, vote thereon in accordance with their best judgment.                

 Any proposal by a shareholder intended to be presented at the 2000 annual
meeting of shareholders must have been received by Duke at its principal        
executive offices located at 8888 Keystone Crossing, Suite 1200, Indianapolis,  
Indiana 46240-2438 not later than November 22, 1999 for inclusion in Duke's     
proxy statement and form of proxy relating to Duke's 2000 annual meeting of     
shareholders. Duke's Board will review any shareholder proposals that are filed 
as required, and will determine whether such proposals meet the criteria for    
inclusion in the proxy solicitation materials or for consideration at the 2000  
annual meeting. In addition, Duke's By-laws provide that any shareholder wishing
to nominate a candidate for director or to propose other business at the 2000   
annual meeting must give Duke written notice at its principal executive offices 
no earlier than January 27, 2000 and no later than February 25, 2000, and the   
notice must provide certain other information as described in the By-laws.      
Copies of Duke's By-laws are available to shareholders free of charge upon      
request to Duke's Investor Relations Department. Duke retains discretion to vote
proxies on matters of which it is not properly notified.                        

WEEKS                                                                           

  VOTING RIGHTS; VOTES REQUIRED FOR APPROVAL.  The Weeks Board has fixed the
close of business on May 3, 1999 as the record date for the determination of    
holders of Weeks common shares entitled to notice of and to vote at the Weeks   
meeting. On April 27, 1999 there were 19,754,085 Weeks common shares            
outstanding, which were held by approximately 190 record holders. As of April   
27, 1999, Directors and executive officers of Weeks beneficially owned an       
aggregate of 799,658 Weeks common shares (excluding shares subject to options)  
or approximately 4% of the outstanding Weeks common shares. Certain directors   
and executive officers of Weeks and entities controlled by them have agreed to  
vote all of their Weeks common shares, representing approximately 2% of Weeks'  
outstanding common shares, in favor of the merger and the merger agreement and  
against any competing transaction. See "The Merger and the Merger               
Proposal--Voting Agreements."

THE MERGER AND THE MERGER PROPOSAL

THE MERGER PROPOSAL                                                             

 The shareholders of Duke and Weeks are being asked to approve a merger of
Weeks with and into Duke and the merger agreement between Duke and Weeks        
pursuant to which the merger will occur. Approval of the merger will also       
constitute approval of amendments to Duke's Article of Incorporation that will  
take effect at the effective time of the merger and will change Duke's name to  
Duke-Weeks Realty Corporation for a period of two years following the effective 
date of the merger and increase the maximum number of common shares that Duke is
authorized to issue from 150,000,000 to 250,000,000. Approval of the merger will
also constitute approval of an additional amendment to Duke's Articles of       
Incorporation that would take effect two years after the effective time of the  
merger and at such time would change the combined company's name to Duke Realty 
Corporation, unless the combined company's Board of Directors recommends against
changing the name. The Board of Directors of Duke and the Board of Directors of 
Weeks have approved the merger of Weeks into Duke and recommend that their      
shareholders vote in favor of the merger.                                       

Pursuant to the merger agreement, at the effective time of the merger:  

- Weeks will be merged with and into Duke, with Duke being the surviving
entity;                                                             

   - each issued and outstanding Weeks common share will be converted into the
right to receive 1.38 Duke common shares;                           

- each issued and outstanding Weeks 8.0% Series A cumulative redeemable 
      preferred share will be converted into the right to receive one preference
     share representing 1/1,000 of an 8.0% Duke Series F cumulative redeemable
  preferred share having substantially identical rights and preferences;

 - each issued and outstanding Weeks 8.625% Series D cumulative redeemable
      preferred share will be converted into the right to receive one preference
share representing 1/1,000 of an 8.625% Duke Series H cumulative    
redeemable preferred share having substantially identical rights and
preferences; and                                                    

- the surviving company will be named Duke-Weeks Realty Corporation.    

Duke will issue approximately 27.3 million common shares to Weeks common
shareholders in the merger. Duke OP will issue approximately 10.1 million common
units of limited partnership interests to limited partners of Weeks OP in the OP
merger. Each Duke OP common unit will be exchangeable by the holders of the     
units for one Duke common share or, if Duke elects, the cash value of one Duke  
common share. The common shares that Duke will issue in the merger, plus the    
common shares Duke will reserve for issuance upon exchange of the Duke OP common
units issued in the OP merger, will represent 27.7% of the outstanding          
Duke-Weeks common shares which will be outstanding after the merger or          
potentially issuable upon exchange of outstanding Duke-Weeks OP common units.   
This information is based on the number of common shares of Duke and Weeks and  
the number of common units of Duke OP and Weeks OP outstanding on March 1, 1999 
and does not take into account shares issuable upon the exercise of outstanding 
stock options and warrants.                                                     

    The merger cannot be completed unless the majority of the outstanding common
shares of each company approve it. Your vote is very important.                 

DUKE'S BOARD RECOMMENDATION                                                     

The members of Duke's Board of Directors have unanimously approved and  
declare advisable and recommend that the Duke shareholders vote "FOR" the merger
of Weeks with and into Duke. The

affirmative vote of the holders of at least a majority of the outstanding Duke  
common shares is required to approve the merger proposal.                       

WEEKS' BOARD RECOMMENDATION                                                     

The members of Weeks' Board of Directors have unanimously approved and  
declare advisable and recommend that the Weeks shareholders vote "FOR" the      
merger of Weeks with and into Duke. The affirmative vote of the holders of at   
least a majority of the outstanding Weeks common shares is required to approve  
the merger proposal.                                                            

EFFECT OF THE MERGER                                                            

As a result of the merger and without any action on the part of Weeks'  
shareholders, at the effective time of the merger, each Weeks common share and  
preferred share will cease to be outstanding, will be canceled and retired and  
will cease to exist. Each holder of a certificate representing Weeks common     
shares or Weeks preferred shares will thereafter cease to have any rights with  
respect to such shares, except the right to receive the applicable merger       
consideration upon the surrender of such certificate. Promptly after the        
effective time of the merger, Duke will deposit with an exchange agent, a bank  
or trust company, certificates representing the Duke shares to be issued in the 
merger. The exchange agent will mail a letter of transmittal and instructions to
each holder of a certificate representing Weeks shares, as of the effective     
time, for use in effecting the surrender of their Weeks stock certificates in   
exchange for certificates representing Duke shares. See "The Merger             
Agreement--Exchange of Weeks Shares."                                           

BACKGROUND OF THE MERGER                                                        

Historically, Duke has grown through acquisitions of portfolios of      
properties and small real estate companies, as well as through the development  
of properties located in the Midwest. Beginning in 1998, and based on the belief
that significant consolidation was likely in the U.S. REIT industry, Duke's     
management decided to explore opportunities for growth through strategic        
business combinations. As an initial step in this process, Duke's management    
sought to arrange meetings with the senior management of companies which Duke   
considered to be part of its peer group in an effort to learn about their       
management philosophies, their market positions and the quality and nature of   
their assets.                                                                   

Since its inception, Weeks' business objective has been to increase     
shareholder value by, among other things, increasing per share cash available   
for distribution. A key strategy used by Weeks to achieve this objective has    
been the acquisition and development of institutional-quality industrial and    
suburban office properties, including the strategic expansion into new          
geographic markets through the acquisition of property portfolios. In light of  
the consolidation trend developing in the REIT industry in 1997 and the         
increasing difficulty publicly held REITs encountered raising funds in the      
equity capital markets, beginning in late 1997, Weeks' management began         
exploring additional strategic alternatives to achieve its business objectives. 
As part of this process, Weeks consulted with Goldman Sachs, its historical     
financial advisor, regarding Weeks' existing business plan, general industry    
conditions, and possible strategic alternatives such as the acquisition of or   
merger with another publicly held REIT. No specific course of action or         
acquisition or merger candidates were discussed. In addition, at industry       
conferences and similar events during late 1997 and early 1998, A. Ray Weeks,   
Jr., Weeks' chief executive officer, met informally with the chief executive    
officers of several publicly held REITs, including Thomas L. Hefner, Duke's     
chief executive officer, to discuss industry trends, management philosophies and
market conditions.                                                              

   At the regularly scheduled meeting of the Weeks Board on November 21, 1997,
Mr. Weeks briefly outlined the ongoing discussions between management and       
Goldman Sachs, and the Weeks Board had a general discussion regarding the       
relative benefits and detriments of the strategic alternatives management had   
been analyzing, and the publicly held REITs that management considered to be in 
Weeks' peer group of companies.

   In January 1998, Mr. Hefner and Darell E. Zink, Jr., Duke's chief financial
officer, met with Mr. Weeks, David P. Stockert, Weeks' chief financial officer, 
and Thomas D. Senkbeil, Weeks' chief investment officer, in Atlanta. During the 
meeting, the parties discussed the real estate industry generally and in their  
particular markets and their respective operating philosophies. There were no   
specific discussions regarding a combination of the two companies. There were   
similar meetings between Messrs. Hefner and Weeks in February, June and July of 
1998. None of these meetings included any specific discussions regarding a      
combination of the two companies.                                               

    In early February 1998, Weeks' management again consulted with Goldman Sachs
regarding possible acquisition and merger candidates. At the regularly scheduled
meeting of the Weeks Board on February 13, 1998, Mr. Weeks briefed the Weeks    
Board about the informal meetings between Weeks' management and the senior      
management of several publicly held REITs, including the meetings with Messrs.  
Hefner and Zink described above. In addition, the Weeks Board continued its     
discussion concerning strategic alternatives, including the possible candidates 
identified by Goldman Sachs. Following a lengthy discussion, the Weeks Board    
concluded that current market conditions did not support the implementation of  
any of the alternatives discussed, but recommended that management continue     
analyzing Weeks' strategic alternatives in light of its business objective of   
increasing shareholder value.                                                   

Between February and November 1998, members of Weeks' senior management 
continued to meet informally with management of other publicly held REITs,      
including Duke, and to narrow the list of possible acquisition or merger        
candidates. None of these meetings involved any specific discussions or         
proposals regarding a possible acquisition or business combination.             

    On July 23, 1998, Mr. Hefner briefed Duke's Board about the discussions that
had taken place to date with Weeks and other companies.                         

    There were no further discussions between Duke and Weeks until September 15,
1998, when Mr. Zink had a breakfast meeting with Mr. Weeks before an industry   
conference. Messrs. Zink and Weeks discussed the management personnel of each of
the companies and discussed the state of the REIT industry, which was becoming  
constrained in its ability to raise capital.                                    

On October 23, 1998, Duke's executive committee met to discuss strategic
alternatives available to Duke, including the possibility of Duke's expanding   
its focus from the Midwest to new markets through a merger.                     

On November 17, 1998, at the annual retreat of the Weeks Board, Goldman 
Sachs discussed the current REIT market environment, Weeks' market position     
relative to several publicly held REITs considered to be in Weeks' peer group,  
possible strategic alternatives and its recommended course of action. Among the 
alternatives discussed were a strategic sale of assets, a merger with another   
REIT, an acquisition of an existing REIT or continuation of Weeks' existing     
strategy. After a lengthy discussion, the Weeks Board concluded that none of the
alternatives involving a sale or merger of the company or the acquisition of an 
existing REIT were feasible at that time on favorable terms. Accordingly, the   
Weeks Board determined that the course of action consistent with its business   
objective of increasing shareholder value would be to continue executing its    
existing strategy.                                                              

On November 30, 1998, Mr. Weeks was contacted by and met with the chief 
executive officer of another publicly held REIT ("Company A") to discuss their  
respective companies, including their properties, markets and operating         
philosophies. During this meeting Mr. Weeks and Company A's chief executive     
officer discussed in general terms a possible combination of the two companies, 
but the discussion did not include any specific material terms of such a        
combination. Following the meetings with Duke and Company B described below, Mr.
Weeks decided not to pursue further discussions with Company A.

    On December 9, 1998, Messrs. Hefner and Weeks met in Indianapolis to discuss
the personnel of their respective organizations and the prospects of a business 
combination involving Duke and Weeks. Messrs. Hefner and Weeks continued these  
discussions in Atlanta on January 22, 1999.                                     

  Shortly following Mr. Weeks' December 9 meeting with Mr. Hefner, Mr. Weeks
was contacted by the chief executive officer of another publicly held REIT      
("Company B"), at which time the chief executive officer expressed a desire to  
begin a dialogue with Weeks' management concerning a possible business          
combination. During this discussion, Mr. Weeks and Company B's chief executive  
officer talked briefly about a possible combination of the two companies, but   
the discussion did not include any specific terms of such a combination.        
Following this meeting, Mr. Weeks and Company B's chief executive officer agreed
to continue discussing a possible business combination of the two companies.    

   In early January 1999, Weeks' senior management met internally and with its
legal advisors to discuss Mr. Weeks' meetings and discussions with management of
Duke, Company A and Company B. Following these meetings, in a letter to each    
director dated January 7, 1999, Mr. Weeks informed the Weeks Board of the       
existence of these discussions and the meetings with the chief executive        
officers of Duke, Company A and Company B. During the Weeks Board's regularly   
scheduled conference call on January 13, 1999, Mr. Weeks described his          
discussions to date with Messrs. Hefner and Zink and the chief executive        
officers of Company A and Company B. Mr. Weeks reviewed management's views of   
the interest Duke, Company A and Company B had in pursuing discussions          
concerning a strategic merger with Weeks. The Weeks Board recommended that      
Weeks' management continue to pursue these discussions with Duke and Company B  
to determine if a business combination with either company was desirable, but   
not to hold exclusive discussions with either Duke or any other company,        
including Company B, in order to maximize the potential value to Weeks'         
shareholders.                                                                   

 On January 15, 1999, Mr. Stockert met with the chief financial officer of
Company B to discuss systems integration, operating strategies and the          
management of the two companies. On January 25 and 26, 1999, the chief executive
officer and chief financial officer of Company B met with Weeks' senior         
management in Atlanta to discuss the integration of the two companies and to    
visit certain of Weeks' properties in Atlanta. The parties continued these      
discussions on February 7 and 8, 1999, when Messrs. Weeks, Senkbeil and Forrest 
W. Robinson, Weeks' president and chief operating officer, met with Company B's 
senior management and visited certain of Company B's properties.                

 At a meeting of Duke's Board held on January 27, 1999, Mr. Hefner briefed
the Board on the discussions he had with Mr. Weeks and the challenges and       
opportunities associated with expanding Duke's focus beyond the Midwest.        

On February 3, 1999, Weeks entered into a confidentiality agreement with
Duke, pursuant to which each company agreed to maintain the confidentiality of  
the non-public information provided to each other in connection with each       
company's due diligence and financial analysis of the other company.            

    On February 4, 1999, members of Weeks' senior management met with members of
Duke's executive committee at Duke's regional offices. Messrs. Zink, Stockert   
and Dennis D. Oklak, Duke's chief administrative officer, met to discuss        
integrating the systems of the companies and the likely accounting treatment of 
a combination of the companies. During the weeks of February 8 and February 15, 
representatives of Duke and Weeks visited most of the properties owned or being 
developed by the two companies.                                                 

On February 5, 1999, Mr. Hefner met with Mr. Weeks and Mr. Senkbeil to  
discuss management assignments for the personnel of a combined company. Mr.     
Hefner continued these discussions with Mr. Weeks on February 9, 1999.          

On February 10, 1999, the Weeks Board held a special meeting, which was 
attended by lawyers from King & Spalding, Weeks' legal counsel. Mr. Weeks       
described his discussions to date with Duke and Company B, and the potential    
benefits to the Weeks' shareholders from a merger with either Duke or Company B.
The Board then discussed with legal counsel the fiduciary duties of the Weeks   
Board to the

Weeks shareholders and the mechanics and processes involved in a potential      
merger transaction. Mr. Weeks then reviewed materials prepared by management and
Goldman Sachs, which included an analysis of the relative market positions      
within the REIT industry of each of Weeks, Duke and Company B, an overview of   
each of Duke and Company B, and a summary of a combined company following a     
Weeks/ Duke and Weeks/Company B merger. Mr. Weeks also described the business,  
properties and operations of Duke and Company B, including specifically the     
quality of their respective properties, their market capitalization, their cost 
of capital and their management. The Weeks Board further discussed generally the
perceived benefit to Weeks and its shareholders of a merger with Duke and a     
merger with Company B. Based upon the information provided to the Weeks Board   
and their discussions with management regarding the potential transactions, the 
Weeks Board determined that Weeks should evaluate further a potential business  
combination with Duke and authorized Weeks' senior management to continue the   
discussions with Duke regarding a possible transaction. The Weeks Board also    
authorized management to retain Goldman Sachs to act as Weeks' financial advisor
in connection with its evaluation of a potential business combination with Duke.
No formal action was taken at the meeting with respect to the merger.           

 At a meeting of Duke's Board on February 11, 1999, Mr. Hefner briefed the
Board on the discussions held to date with Weeks. At this meeting, the Duke     
Board authorized management to retain legal and financial advisors to assist    
management in evaluating a transaction between Duke and Weeks. Duke engaged     
Merrill Lynch Pierce, Fenner & Smith Incorporated to act as its financial       
advisor and Rogers & Wells LLP as its legal advisor in connection with its      
evaluation of a potential business combination with Weeks.                      

  On February 15, 1999, representatives of Duke and Weeks met in New York at
the offices of Duke's legal counsel. Mr. Zink, Mr. Oklak and James R.           
Windmiller, Duke's Vice President--Taxation, were present from Duke. Mr. Weeks, 
Mr. Stockert and Elizabeth C. Belden, Weeks' general counsel, were present from 
Weeks. Representatives from Duke's and Weeks' outside legal counsel and         
financial advisors were also present. At this meeting, Weeks' representatives   
reviewed Weeks' property portfolio and described Weeks' joint venture           
arrangements. The parties discussed a schedule for completing legal and         
financial due diligence of the companies and also discussed potential legal     
structures for a combination of the two companies. Messrs. Zink and Weeks had a 
further meeting on the evening of February 15, 1999 at which they discussed the 
strategic vision of the combined company and how to integrate effectively the   
operations of the companies.                                                    

  A data room containing Weeks due diligence material was established at the
offices of Weeks' legal counsel. Representatives of Duke and its legal counsel  
visited the data room during the week of February 15. A similar data room       
containing Duke due diligence material was established near Duke's headquarters 
in Indianapolis. Weeks and its legal counsel visited the data room during the   
week of February 15. There were also numerous telephone conversations during    
that week between the legal advisors for the two companies regarding due        
diligence and legal structure, as well as conversations between the companies'  
financial advisors regarding financial diligence and financial analyses of the  
companies.                                                                      

On February 18, 1999, drafts of a merger agreement and related documents
were sent by Duke's counsel to Duke and Weeks and their respective legal and    
financial advisors. On February 19, 1999, representatives of Merrill Lynch and  
Goldman Sachs conducted due diligence meetings with the management of Duke and  
Weeks in Indianapolis and Atlanta.                                              

  On February 22, 1999, Messrs. Zink and Oklak and representatives of Duke's
legal counsel met in New York with Mr. Stockert, Ms. Belden and representatives 
of Weeks' legal counsel to discuss the draft merger agreement and due diligence 
issues that had arisen during the course of the parties' due diligence reviews. 

  During the week of February 22, Duke and Weeks, in consultation with their
legal and financial advisors, reviewed and commented on the merger agreement and
finalized the terms of the merger. The

principal issues discussed during these negotiations were the exchange ratio,   
covenants of Duke and Weeks with regard to the conduct of their business during 
the period between signing the merger agreement and closing the merger, the     
appropriate amounts of the termination fees and expenses and the circumstances  
under which they should be payable, the conditions under which a breach by      
either party of a representation or warranty would give the non-breaching party 
the right to terminate the merger agreement, the terms of Weeks' existing change
of control agreements, the scope of the amendments which would be made to the   
operating partnership agreement of Duke OP and the effect of the merger on      
Weeks' outstanding stock options.                                               

On February 23, 1999, Duke's Board held a special telephonic meeting in 
which Duke's financial and legal advisors also participated. The Duke Board was 
informed of the status of negotiations with regard to the exchange ratio and the
merger. At the conclusion of the meeting, the Board gave direction and authority
to management regarding the terms of the merger and the approach management     
should take in its negotiations. Later that evening, the parties agreed upon a  
fixed exchange ratio of 1.38 Duke common shares for one common share of Weeks   
and agreed that there would be no adjustment to the exchange ratio for          
fluctuations in the trading prices of Duke or Weeks common shares.              

  The Weeks Board held a special telephonic meeting on February 24, 1999, in
which Weeks' financial and legal advisors participated. During the meeting the  
Weeks Board discussed with management and Weeks' financial and legal advisors   
the status of negotiations with respect to a business combination with Duke,    
including the exchange ratio of 1.38 Duke common shares for one common share of 
Weeks and the composition of senior management and the board of directors of the
combined company. The Weeks Board authorized management to proceed with the     
negotiation of the terms of the merger agreement and related documents on these 
terms.                                                                          

 On the morning of February 28, 1999, a special meeting of the Weeks Board
was held at which members of management and representatives of Weeks' financial 
and legal advisors were present. Mr. Weeks made a presentation to the Weeks     
Board regarding the background and events leading up to the meeting with respect
to the proposed merger with Duke. Mr. Weeks then set forth the reasons he       
believed a strategic merger with Duke would be beneficial to Weeks and its      
shareholders, which reasons are described under the heading "Reasons for the    
Merger--Recommendation of the Weeks Board" below. Legal counsel then described  
for the Weeks Board the due diligence investigation of Duke that had been       
conducted in connection with the proposed merger. Representatives of Goldman    
Sachs then made a presentation regarding the proposed merger with Duke. A       
summary of this presentation is described below under the heading "--Opinion of 
Weeks' Financial Advisor." Goldman Sachs delivered to the Weeks Board its       
opinion that as of that date, the exchange ratio pursuant to the merger         
agreement was fair from a financial point of view to the holders of the         
outstanding Weeks common shares. Weeks' legal counsel then made a presentation  
to the Weeks Board in which it explained the material terms of the proposed     
merger agreement, including closing conditions, termination rights and related  
fees and expense reimbursement provisions, briefed the Weeks Board on certain   
legal issues raised by the proposed merger and advised the Weeks Board of its   
fiduciary duties in connection with the transaction. Following such             
presentations, and after extensive discussion of the advantages and potential   
risks of the proposed merger as described under the heading "Reasons for the    
Merger--Recommendation of the Weeks Board" below, the Weeks Board unanimously   
approved the merger, the merger agreement and the transactions contemplated     
thereby.                                                                        

Also on February 28, 1999, the Duke Board held a meeting to approve the 
merger agreement and the merger. Representatives of Merrill Lynch delivered     
their written opinion that as of that date, the exchange ratio in the merger    
agreement was fair, from a financial point of view, to Duke. Representatives of 
Duke's legal counsel discussed with the Board, among other things, their        
fiduciary duties and the terms of the merger. Duke's Board of Directors reviewed
and discussed the information presented by management and Duke's legal and      
financial advisors, together with the opinion delivered by Merrill Lynch. At the
conclusion of the discussion, Duke's Board of Directors unanimously approved the
merger and the merger agreement.

REASONS FOR THE MERGER; RECOMMENDATION OF THE DUKE BOARD                        

Duke's Board of Directors unanimously approved the merger and the merger
agreement at a meeting held on February 28, 1999. The Duke Board believes that  
the terms of the merger, the merger agreement and the other transactions        
contemplated thereby are advisable and in the best interests of Duke and its    
shareholders. Accordingly, the Duke Board recommends that its shareholders      
approve the merger, the merger agreement and the transactions contemplated      
thereby.                                                                        

In considering the recommendation of the Duke Board with respect to the 
merger, Duke shareholders should be aware that if the additional charter        
amendment to the Duke Articles of Incorporation to increase the size of the Duke
Board is approved, 11 of the 12 members of the Duke Board will become directors 
of Duke-Weeks following consummation of the merger. If this amendment is not    
approved, but the merger is approved by the requisite vote of the Duke          
shareholders, then up to eight members of Duke's Board will become directors of 
Duke-Weeks following consummation of the merger. Therefore, Duke's directors    
have interests in the merger that are different than, or in addition to, the    
interests of the shareholders of Duke generally.                                

 In its deliberations with respect to the merger and the merger agreement,
the Duke Board consulted with Duke's management and the financial and legal     
advisors to Duke. The factors considered by the Duke Board include those        
enumerated below. While all of these factors were considered by the Duke Board, 
the Board did not make determinations with respect to each factor. Rather, the  
Board made its judgment with respect to the merger and the merger agreement     
based on the total mix of information available to it, and the judgments of     
individual directors may have been influenced to a greater or lesser degree by  
their individual views with respect to different factors.                       

POSITIVE FACTORS CONSIDERED BY THE DUKE BOARD                                   

In making its determination with respect to the merger, the Duke Board  
considered the following material positive factors:                             

    - The merger will combine the assets of Weeks and Duke, strengthening one of
  the largest real estate investment trusts in the Midwest and expanding
     Duke into desirable new markets in the southeast United States and Texas.
     Duke-Weeks is expected to have a pro forma total market capitalization of
   approximately $5.2 billion, based on the closing price of Duke's common
    shares on February 26, 1999 (the last full trading day before the merger
was publicly announced) and the outstanding principal amount of     
indebtedness of the two companies on December 31, 1998.             

- The Duke Board believes that the combined company resulting from the  
 merger will have a strong balance sheet. The pro forma ratio of total
      long-term debt to total long-term undepreciated book capitalization of the
combined company as of December 31, 1998 is approximately 57%. In   
     addition, the Duke Board believes that the merger will result in improved
     liquidity for Duke shareholders as a result of the increased total equity
     capitalization of the combined company and an increased trading volume of
the securities of the combined company.                             

   - The merger will give Duke market presence and new platforms for growth in
    key markets. Weeks' assets are located in growth-oriented markets in the
     southeast United States and Texas. After the merger, the combined company
     will own assets totaling in excess of 30 million square feet in these key
Sunbelt markets.                                                    

 - Duke management believes that the operating philosophies and systems of
  Duke and Weeks are sufficiently similar that the operations of the two
companies can be combined without significant costs or disruption to
operations.

    - The opinion of Merrill Lynch described below to the effect that, as of the
     date of such opinion, and based upon and subject to the matters stated in
      such opinion, the exchange ratio of 1.38 Duke common shares for each Weeks
common share is fair, from a financial point of view, to Duke.      

NEGATIVE FACTORS CONSIDERED BY THE DUKE BOARD                                   

The Duke Board also considered the matters described above under "Risk  
Factors" as well as the following potentially negative factors in its           
deliberations concerning the merger.                                            

  - Because the exchange ratio of Duke common shares for Weeks common shares
      is fixed at 1.38, the common shares that Duke will be required to issue in
  the merger may have a greater value than the value contemplated at the
    time the merger was signed because of an increase in the market price of
Duke common shares.                                                 

   - Duke shareholders will not maintain their current percentage ownership of
Duke in the combined company.                                       

In view of the wide variety of factors considered by the Duke Board, the
Duke Board did not quantify or otherwise attempt to assign relative weights to  
the specific factors considered in making its determination. However, in the    
view of the Duke Board, the potentially negative factors considered by it were  
not sufficient, either individually or collectively, to outweigh the positive   
factors considered by it in its deliberations relating to the merger.           

OPINION OF DUKE'S FINANCIAL ADVISOR                                             

Merrill Lynch has acted as the financial advisor to the Duke Board in   
evaluating the merger between Duke and Weeks. On February 28, 1999, Merrill     
Lynch delivered its written opinion (the "Merrill Lynch Opinion") to the Duke   
Board stating that, as of February 28, 1999, based upon and subject to the      
assumptions made, matters considered and limits of review set forth therein, the
exchange ratio of 1.38 Duke common shares for each Weeks common share was fair, 
from a financial point of view, to Duke.

READ THE OPINION IN ITS ENTIRETY. THE DESCRIPTION OF THE MERRILL LYNCH OPINION  
SET FORTH HEREIN IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF  
THE MERRILL LYNCH OPINION. THE MERRILL LYNCH OPINION IS ADDRESSED TO THE DUKE   
BOARD AND ADDRESSES ONLY THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, TO DUKE

NEGOTIATIONS BETWEEN DUKE AND WEEKS AND WAS APPROVED BY THE DUKE BOARD.         

In connection with the preparation of the Merrill Lynch Opinion, Merrill
Lynch, among other things:                                                      

- reviewed certain publicly available business and financial information
 relating to Duke and Weeks which Merrill Lynch deemed to be relevant;

  - reviewed certain information, including financial forecasts, relating to
the business, earnings, funds from operations, adjusted funds from  
      operations, cash flow, assets, liabilities and prospects of Duke and Weeks
   furnished to Merrill Lynch by Duke and Weeks, as well as the amount and
   timing of the savings and related synergies expected to result from the
    merger (the "Expected Synergies") furnished to Merrill Lynch by Duke and
Weeks;

- conducted discussions with members of management of Duke and Weeks    
 concerning the matters described in the two clauses above, as well as
    their respective businesses and prospects before and after giving effect
to the merger and the Expected Synergies;                           

- reviewed the market prices and valuation multiples for the Duke common
      shares and the Weeks common shares and compared them with those of certain
publicly traded companies that Merrill Lynch deemed relevant;       

- reviewed the results of operations of Duke and Weeks and compared them
     with those of certain publicly traded companies that Merrill Lynch deemed
to be relevant;                                                     

- compared the proposed financial terms of the merger with the financial
terms of certain other transactions which Merrill Lynch deemed to be
relevant;                                                           

    - participated in certain discussions and negotiations among representatives
of Duke and Weeks and their financial and legal advisors;           

- reviewed the potential pro forma impact of the merger on Duke;        

   - reviewed a draft of the merger agreement, and assumed that the final form
 would not differ in any respect that is material to the Merrill Lynch
Opinion; and                                                        

  - reviewed such other financial studies and analyses and took into account
such other matters as Merrill Lynch deemed necessary, including its 
assessment of general economic, real estate, market and monetary    
conditions.                                                         

In preparing the Merrill Lynch Opinion, Merrill Lynch assumed and relied
upon, without assuming any responsibility for verification, the accuracy and    
completeness of all information supplied or otherwise made available to Merrill 
Lynch, discussed with or reviewed by or for Merrill Lynch, or publicly          
available. With respect to the financial forecast information and the Expected  
Synergies furnished to or discussed with Merrill Lynch by Duke or Weeks, Merrill
Lynch assumed that they have been reasonably prepared on bases reflecting the   
best currently available estimates and judgment of Duke's or Weeks' management  
as to the expected future financial performance of Duke or Weeks, as the case   
may be, and the Expected Synergies. Merrill Lynch expressed no view as to such  
projections or information or the assumptions on which they are based. Merrill  
Lynch did not assume any responsibility for making or obtaining any independent 
evaluation or appraisal of any of the assets or liabilities of Duke or Weeks.   
Merrill Lynch further assumed that the merger will qualify as a tax-free        
reorganization for United States federal and any applicable state income tax    
purposes. Merrill Lynch also assumed that the merger will not change the real   
estate investment trust status of the pro forma entity for federal income tax   
purposes.                                                                       

  For purposes of rendering the Merrill Lynch Opinion, Merrill Lynch assumed
in all respects material to its analysis that the representations and warranties
of each party contained in the merger agreement were true and correct, that each
party would perform all of the covenants and agreements required to be performed
by it under the merger agreement, and that all conditions to the consummation of
the merger would be satisfied without waiver thereof. Merrill Lynch assumed that
in the course of obtaining the necessary regulatory or other consents or        
approvals (contractual or otherwise) for the merger, no restrictions, including 
any divestiture requirements, or amendments or modifications, will be imposed   
that will have an adverse effect on the contemplated benefits of the merger. The
Merrill Lynch Opinion is necessarily based upon market, real estate, economic   
and other conditions as they exist and can be evaluated on, and on the          
information made available to Merrill Lynch as of, February 26, 1999. Merrill   
Lynch assumed no responsibility to update or revise the Merrill Lynch Opinion   
based upon circumstances or events occurring after February 26, 1999.           

The following is a summary of the material financial and comparative    
analyses performed by Merrill Lynch in arriving at the Merrill Lynch Opinion.

THE SUMMARY OF FINANCIAL ANALYSES INCLUDE INFORMATION PRESENTED IN TABULAR      
FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT OF EACH SUMMARY.    

VALUATION OF WEEKS.                                                     

 HISTORICAL TRADING PERFORMANCE AND CURRENT CAPITALIZATION.  Merrill Lynch
reviewed certain trading information for Weeks and, on the basis thereof,       
calculated its market value, market capitalization and trading multiples based  
on its stock price as of February 24, 1999 of $26.75. For this purpose, Merrill 
Lynch defined "total market capitalization" as the market value of Weeks' common
equity (including operating partnership units as if converted into common       
equity), plus preferred shares at liquidation value as of December 31, 1998,    
plus total debt as of December 31, 1998. Merrill Lynch then calculated the      
market value of Weeks as a multiple of projected Funds from Operations ("FFO")  
and FFO less recurring capital expenditures ("AFFO") provided by Weeks'         
management. Weeks' projected FFO multiples for 1999 and 2000 were 8.9x and 8.1x,
respectively, and the projected AFFO multiples for 1999 and 2000 were 9.9x and  
9.1x, respectively.                                                             

   Merrill Lynch reviewed Duke's offer for Weeks and, on the basis thereof and
using publicly available share price information for the Duke common shares as  
of February 24, 1999, calculated an aggregate net offer value (the "Net Offer   
Value") of $819.4 million. Based upon Weeks' actual preferred shares, debt and  
cash balances as of December 31, 1998, Merrill Lynch also calculated an         
aggregate transaction value (the "Transaction Value") of $1,719.0 million, which
consisted of the Net Offer Value, plus Weeks' preferred shares at their         
liquidation value of $250.0 million and Weeks' debt of $651.2 million, less     
Weeks' cash balance of $1.5 million. Merrill Lynch also calculated Net Offer    
Value transaction multiples based on projections provided by Weeks' management  
of its projected FFO and AFFO of 10.0x and 11.2x, respectively, for 1999 and    
9.2x and 10.3x, respectively, for 2000.                                         

  ANALYSIS OF SELECTED COMPARABLE PUBLICLY TRADED COMPANIES.  Using publicly
available information and estimates of future financial results published by    
First Call, an industry service provider of earnings estimates based on an      
average of earnings estimates published by various investment banking firms     
("First Call"), and taken from Merrill Lynch Equity Research, Merrill Lynch     
compared certain financial and operating information and ratios for Weeks with  
the corresponding financial and operating information for a group of publicly   
traded companies engaged primarily in the ownership, management, operation and  
acquisition of industrial and office properties which Merrill Lynch deemed to be
reasonably comparable to Weeks. For the purpose of its analyses, the following  
companies were used as comparable companies to Weeks: AMB Property Corporation, 
Cabot Industrial Trust, CenterPoint Properties Trust, First Industrial Realty   
Trust, Inc., Liberty Property Trust and ProLogis Trust (collectively, the "Weeks
Comparable Companies").                                                         

  Merrill Lynch's calculations resulted in the following relevant ranges for
the Weeks Comparable Companies and for Weeks as of February 24, 1999:

   Based on projected 2000 FFO multiples, this analysis results in a per share
valuation of between $24.75 and $32.67.                                         

    None of the Weeks Comparable Companies is identical to Weeks. Accordingly, a
complete analysis of the results of the foregoing calculations cannot be limited
to a quantitative review of such results and involves complex considerations and
judgments concerning differences in financial and operating characteristics of  
the Weeks Comparable Companies and other factors that could affect the public   
trading of the Weeks Comparable Companies, as well as that of Weeks. In         
addition, the multiples of market value to projected 1999 and 2000 FFO and AFFO 
for the Weeks Comparable Companies are based on projections prepared by research
analysts using only publicly available information. Accordingly, such estimates 
may or may not prove to be accurate.                                            

COMPARABLE TRANSACTIONS ANALYSIS.  Merrill Lynch also compared certain  
financial ratios of the merger with those of other selected mergers and         
strategic transactions involving real estate investment trusts which Merrill    
Lynch deemed to be relevant. These transactions were ProLogis Trust's pending   
merger with Meridian Industrial Trust, Inc., Reckson Associates Realty          
Corp./Crescent Real Estate Equities Company's pending merger with Tower Realty  
Trust, Inc., Equity Office Properties Trust's merger with Beacon Properties     
Corporation and Highwoods Properties, Inc.'s merger with Crocker Realty Trust,  
Inc.                                                                            

  Using publicly available information and estimates of financial results as
published by First Call, Merrill Lynch calculated the premium of the implied    
offer value per share relative to the acquired company's stock price on the day 
before the announcement of the respective transaction, and as a multiple of the 
projected forward year FFO for the transaction. This analysis resulted in the   
following relevant ranges for the transactions found by Merrill Lynch to be     
comparable to the merger:

                                                          LOW      MEAN        HIGH    
                                                       ---------   -----     --------- 
                                                                                       
Premium to market.....................................       7.3%     18.1%       28.3%

Multiple of projected FFO.............................      10.3x     12.8x       15.5x

    This analysis results in a per share valuation of between $31.11 and $33.52.

 DISCOUNTED CASH FLOW ANALYSIS--DISCOUNTED DIVIDEND METHOD.  Merrill Lynch
performed a discounted cash flow analysis (I.E., an analysis of the present     
value calculated as of December 31, 1998 of the projected levered cash flows for
the periods using the discount rates indicated) of Weeks based upon projections 
provided by Weeks' management for the years 1999 through 2003, inclusive, using 
discount rates reflecting an equity cost of capital ranging from 13.0% to 17.0% 
and terminal value multiples for 2003 FFO ranging from 9.5x to 10.5x. Based upon
Weeks' projections for the years 1999 through 2003, the range of present values 
per Weeks common share was $27.08 to $34.07.                                    

    NET ASSET VALUATION ANALYSIS.  Merrill Lynch performed a net asset valuation
for Weeks based on an asset-by-asset real estate valuation of Weeks' properties,
an estimation of the current value for Weeks' other assets and liabilities, and 
Weeks' debt balances as of December 31, 1998. The real estate valuation utilized
property specific projections prepared by Weeks' management for 1999. For the   
operating portfolio of Weeks, the valuation utilized the direct capitalization  
method on projected 1999 property net operating income and capitalization rates 
of 9.0% and 10.0%. These calculations indicated a per share net asset valuation 
range for Weeks of $26.64 to $32.22.                                            

VALUATION OF DUKE.                                                      

 HISTORICAL TRADING PERFORMANCE AND CURRENT CAPITALIZATION.  Merrill Lynch
reviewed certain trading information for Duke and, on the basis thereof,        
calculated its market value, market capitalization and trading multiples based  
on its stock price as of February 24, 1999 of $22.00. For this purpose, Merrill 
Lynch

defined "total market capitalization" as market value of Duke's common equity   
(including operating partnership units as if converted into common equity), plus
preferred shares at liquidation value as of December 31, 1998, plus total debt  
as of December 31, 1998. Merrill Lynch then calculated the market value of Duke 
as a multiple of projected FFO and AFFO provided by Duke's management. Duke's   
projected FFO multiples for 1999 and 2000 were 10.6x and 9.5x, respectively, and
the projected AFFO multiples for 1999 and 2000 were 12.7x and 10.5x,            
respectively.                                                                   

  ANALYSIS OF SELECTED COMPARABLE PUBLICLY TRADED COMPANIES.  Using publicly
available information and estimates of future financial results published by    
First Call and taken from Merrill Lynch Equity Research, Merrill Lynch compared 
certain financial and operating information and ratios for Duke with the        
corresponding financial and operating information for a group of publicly traded
companies engaged primarily in the ownership, management, operation and         
acquisition of industrial and office properties which Merrill Lynch deemed to be
reasonably comparable to Duke. For the purpose of its analyses, the following   
companies were used as comparable companies to Duke: Spieker Properties, Inc.,  
CenterPoint Properties Trust, ProLogis Trust, AMB Property Corporation, Liberty 
Property Trust and First Industrial Realty Trust, Inc. (collectively, the "Duke 
Comparable Companies").                                                         

  Merrill Lynch's calculations resulted in the following relevant ranges for
the Duke Comparable Companies and for Duke as of February 24, 1999:

None of the Duke Comparable Companies is, of course, identical to Duke. 
Accordingly, a complete analysis of the results of the foregoing calculations   
cannot be limited to a quantitative review of such results and involves complex 
considerations and judgments concerning differences in financial and operating  
characteristics of the Duke Comparable Companies, and other factors that could  
affect the public trading of the Duke Comparable Companies, as well as that of  
Duke. In addition, the multiples of market value to projected 1999 and 2000 FFO 
and AFFO for the Duke Comparable Companies are based on projections prepared by

estimates may or may not prove to be accurate.                                  

 DISCOUNTED CASH FLOW ANALYSIS--DISCOUNTED DIVIDEND METHOD.  Merrill Lynch
performed a discounted cash flow analysis (I.E., analysis of the present value  
of the projected levered cash flows for the periods using the discount rates    
indicated) of Duke based upon projections provided by Duke's management for the 
years 1999 through 2003, inclusive, using discount rates reflecting an equity   
cost of capital ranging from 13.0% to 17.0% and terminal value multiples for    
2003 FFO ranging from 10.3x to 11.3x. Based upon Duke's projections for the     
years 1999 through 2003, the range of present values per Duke common share was  
$19.70 to $24.62.                                                               

NET ASSET VALUATION ANALYSIS.  Merrill Lynch also performed a net asset 
valuation for Duke based on an asset-by-asset real estate valuation of Duke's   
properties, an estimation of the current values for Duke's other assets and     
liabilities, and an estimation of Duke's debt balances as of December 31, 1998. 
The real estate valuation utilized property specific projections prepared by    
Duke's management for 1999. For the operating portfolio of Duke, the valuation  
utilized the direct capitalization method on projected 1999 property net        
operating income and a range of capitalization rates of 8.8% to 10.5%. These    
calculations indicated a per share net asset valuation range for Duke of $19.66 
to $23.05.                                                                      

PRO FORMA MERGER CONSEQUENCES.                                          

IMPLIED EXCHANGE RATIO ANALYSIS--COMPARATIVE VALUATIONS.  Merrill Lynch 
utilized the results of three valuation methodologies: public comparables       
analysis; discounted cash flow analysis--discounted dividend method; and net    
asset value analysis, in order to calculate a range of implied exchange ratios  
for each method, as compared to the 1.38x exchange ratio in the merger. This    
analysis yielded the following ranges:

                                                                  -------------------------------

                                                                  ---------  ---------  ---------

PRO FORMA COMBINATION ANALYSIS.  Merrill Lynch analyzed the pro forma   
effects resulting from the merger, including the potential impact on Duke's     
projected stand-alone FFO per share and the anticipated accretion (I.E., the    
incremental increase) to Duke's FFO per share resulting from the merger. Merrill
Lynch observed that, after giving effect to the Expected Synergies, the merger  
would be accretive to Duke's projected FFO per share in each of the years 1999  
through 2003, inclusive.                                                        

Merrill Lynch also observed that the projected annual dividend per Duke 
common share pro forma for the merger were $1.43, $1.60, $1.77, $1.94 and $2.06 
per Duke common share in 1999, 2000, 2001, 2002 and 2003, implying no reduction 
in Duke's current indicated dividend rate.                                      

  PRO FORMA CONTRIBUTION ANALYSIS.  Weeks' current shareholders will have an
aggregate ownership interest in Duke of approximately 25.9% (on a fully diluted 
basis, assuming the conversion of all OP units and convertible preferred shares)
after the completion of the merger. On a pro forma basis, after giving

effect to the merger and the Expected Synergies and assuming the accuracy of the
estimates provided by the management of Duke and Weeks, the following will be

On the basis of this analysis, Weeks' contribution to the combined      
operations with respect to pro forma EBITDA, FFO and AFFO are greater for 1998  
and 1999 on a percentage basis than the aggregate ownership interest that Weeks 
shareholders would receive in Duke pursuant to the merger.                      

    The summary set forth above does not purport to be a complete description of
the analyses performed by Merrill Lynch in arriving at the Merrill Lynch        
Opinion. The preparation of a fairness opinion is a complex process and not     
necessarily susceptible to partial or summary description. Merrill Lynch        
believes that its analyses must be considered as a whole and that selecting     
portions of its analyses and of the factors considered by it, without           
considering all factors and analyses, could create a misleading view of the     
process underlying the Merrill Lynch Opinion. The process of preparing a        
fairness opinion necessarily requires a broad range of subjective judgment with 
respect to appropriate comparable companies and transactions, appropriate       
multiples of various selected financial data, appropriate discount rates and    
other financial and other facts. Accordingly, any analysis is not mathematical; 
rather it involves complex considerations and judgments. In its analyses,       
Merrill Lynch made numerous assumptions with respect to industry performance,   
general business and economic conditions and other matters, many of which are   
beyond Duke's, Weeks', and Merrill Lynch's control. Any estimates contained in  
Merrill Lynch's analyses are not necessarily indicative of actual values, which 
may be significantly more or less favorable than as set forth therein. Estimated
values do not purport to be appraisals and do not necessarily reflect the prices
at which businesses or companies may be sold in the future, and such estimates  
are inherently subject to uncertainty.                                          

  The Duke Board selected Merrill Lynch to render a fairness opinion because
Merrill Lynch is an internationally recognized investment banking firm with     
substantial experience in transactions similar to the merger and because it is  
familiar with Duke and its business. Merrill Lynch is continually engaged in the
valuation of businesses and their securities in connection with mergers and     
acquisitions, leveraged buyouts, negotiated underwritings, secondary            
distributions of listed and unlisted securities and private placements.         

  Pursuant to a letter agreement dated February 24, 1999, Duke agreed to pay
Merrill Lynch a fee equal to 0.35% of the purchase price (as defined in the     
letter agreement) upon consummation of the merger. Duke also agreed to reimburse
Merrill Lynch for its reasonable out-of-pocket expenses incurred in connection  
with its advisory work, including the reasonable fees and disbursements of its  
legal counsel, subject to certain limitations, and to indemnify Merrill Lynch   
and certain related persons against certain liabilities arising out of or in    
conjunction with its rendering of services under such letter agreement,         
including certain liabilities under the federal securities law.                 

 Merrill Lynch has, in the past, provided financial advisory and financing
services to Duke and may continue to do so and has received, and may receive,   
fees for the rendering of such services. In the ordinary course of its business,
Merrill Lynch may actively trade in the securities of Duke for its own account  
and for the accounts of its customers and, accordingly, may at any time hold a  
long or short position in such securities.                                      

REASONS FOR THE MERGER; RECOMMENDATION OF THE WEEKS BOARD                       

   The Weeks Board of Directors unanimously approved the merger and the merger
agreement at a meeting held on February 28, 1999. The Weeks Board believes that 
the terms of the merger, the merger agreement and                               

41

the other transactions contemplated thereby are advisable and in the best       
interests of Weeks and its shareholders. Accordingly, the Weeks Board recommends
that its shareholders approve the merger, the merger agreement and the          
transactions contemplated thereby.                                              

In considering the recommendation of the Weeks Board with respect to the
merger, Weeks' shareholders should be aware that if the additional charter      
amendment to the Duke Articles of Incorporation increasing the size of the Duke 
Board is approved, ten of the 11 members of the Weeks Board will become         
directors of Duke-Weeks following consummation of the merger. If this amendment 
is not approved, but the merger is approved by the requisite vote of the Duke   
shareholders, then up to seven members of the Weeks Board will become directors 
of Duke-Weeks following consummation of the merger. Also, Weeks directors who   
become Duke-Weeks directors will be eligible to receive stock grants and stock  
options under certain Duke plans. Therefore, the Weeks directors have interests 
in the merger that are different than, or in addition to, the interests of the  
shareholders of Weeks generally.                                                

 In its deliberations with respect to the merger and the merger agreement,
the Weeks Board consulted with Weeks' management and the financial and legal    
advisors to Weeks. The factors considered by the Weeks Board include those      
enumerated below. While all of these factors were considered by the Weeks Board,
the Board did not make determinations with respect to each such factor. Rather, 
the Board made its judgment with respect to the merger and the merger agreement 
based on the total mix of information available to it, and the judgments of     
individual directors may have been influenced to a greater or lesser degree by  
their individual views with respect to different factors.                       

POSITIVE FACTORS CONSIDERED BY THE WEEKS BOARD                                  

In making its determination with respect to the merger, the Weeks Board 
considered the following material positive factors:                             

- Each Weeks common share will be exchanged for 1.38 Duke common shares.
      Consequently, based on the closing price of Duke common shares on February
26, 1999 (the last full trading day before the merger was publicly  
  announced), each Weeks common share would be exchanged for Duke common
     shares in the merger having a value of approximately $30.10 (based on the
February 26, 1999 closing price of Duke common shares of $21.81),   
     representing an 11.47% premium over the closing price of $27.00 for Weeks
common shares on February 26, 1998.                                 

  - The geographic diversification and increased tenant base of the combined
   company will reduce the dependence on any single market or region or on
     any single tenant. Recessions often affect economies of different regions
     and different industries at different times. With a substantial number of
     properties in both the southeastern and midwestern United States and with
     approximately 5,000 tenants, there should be a reduction in the risk that
    a regional economic downturn could affect a large number of the combined
company's properties simultaneously. The Weeks Board believes the   
geographic diversification and larger tenant base resulting from the
merger may smooth the combined company's performance through these  
economic cycles.                                                    

  - Based on the closing price of Duke's common shares on February 26, 1999,
     Duke-Weeks would have a total market capitalization of approximately $5.2
billion. By virtue of its larger size, the Weeks Board believes that
      Duke-Weeks also will have improved access to capital markets, which should
  make additional debt or other financing available upon more attractive
     terms. The Weeks Board also viewed as favorable its belief, based in part
on discussions with financial advisors, that the increased market   
   capitalization would provide Weeks shareholders with enhanced liquidity
following consummation of the merger.                               

- The Weeks Board viewed as favorable the fact that the merger will be  
consummated on a tax-free basis.                                    

  - The Weeks Board believes Duke and Weeks have complementary product focus
and operating strategies, which should result in a more effective   
integration of the two companies.

  - The Weeks Board believes the merger may generate additional efficiencies
through economies of scale and anticipated reductions in expense.   

  - The opinion, analyses and presentations of Goldman Sachs described under
   "--Opinion of Weeks' Financial Advisor" below, including the opinion of
 Goldman Sachs to the effect that, as of the date of such opinion, and
  based upon and subject to certain matters stated therein, the exchange
     ratio pursuant to the merger agreement was fair from a financial point of
view to the holders of outstanding Weeks common shares.             

- Weeks' other strategic alternatives, including the prospects of       
      positioning Weeks for the future and enhancing long-term shareholder value
    by remaining an independent company or by effecting a strategic business
  combination with another company were not as attractive as the current
merger with Duke.                                                   

NEGATIVE FACTORS CONSIDERED BY THE WEEKS BOARD                                  

The Weeks Board of Directors also considered the following potentially  
negative factors in its deliberations concerning the Merger:                    

- The exchange ratio is fixed and not subject to adjustment, and thus, a
      decrease in the trading price of Duke common shares prior to the effective
  time of the merger will reduce the aggregate consideration paid to the
Weeks common shareholders.                                          

    - The risk that the anticipated benefits of the merger to Weeks shareholders
  may not be realized as a result of possible changes in the real estate
     market in general, the inability to achieve the anticipated reductions in
     expenses or other potential difficulties in integrating the two companies
  and their respective operations. In addition, the Board considered the
effect of the public announcement of the merger on Weeks' ability to
retain employees and on the trading price of Weeks' common shares.  

    - The significant costs involved in connection with consummating the merger,
 the substantial management time and effort required to effectuate the
 merger and integrate the businesses of Weeks and Duke and the related
disruption to Weeks' operations.                                    

   - The risk that the merger might not be completed based upon the failure to
satisfy certain covenants or closing conditions.                    

   The Weeks Board also considered certain matters described above under "Risk
Factors," including the potential benefits to certain directors and officers    
discussed in "Risk Factors--The Directors and Officers of Weeks May Have        
Interests in the Completion of the Merger that are Different From the Interests 
of Weeks' Shareholders."                                                        

 In view of the wide variety of factors considered by the Weeks Board, the
Weeks Board did not quantify or otherwise attempt to assign relative weights to 
the specific factors that it considered in making its determination. In the view
of the Weeks Board, however, the potentially negative factors considered by it  
were not sufficient, either individually or collectively, to outweigh the       
positive factors considered in its deliberations relating to the merger.        

OPINION OF WEEKS' FINANCIAL ADVISOR                                             

   On February 28, 1999, Goldman Sachs delivered its oral opinion to the board
of directors of Weeks that, as of that date, the exchange ratio pursuant to the 
merger agreement was fair from a financial point of view to the holders of the  
outstanding Weeks common shares. Goldman Sachs confirmed its oral opinion by    
delivery of its written opinion dated February 28, 1999.

shareholders; and                                                   

- certain internal financial analyses and forecasts for Weeks and Duke

  Goldman Sachs also held discussions with members of the senior managements
of Weeks and Duke regarding the strategic rationale for, and the potential      
benefits of, the transaction contemplated by the merger agreement and the past  
and current business operations, financial condition and future prospects of    
their respective companies. In addition, Goldman Sachs:                         

- reviewed the reported price and trading activity for the Weeks common 
shares and the Duke common shares;                                  

    - compared certain financial and stock market information for Weeks and Duke
  with similar information for certain other companies the securities of
which are publicly traded;                                          

 - reviewed the financial terms of certain recent business combinations in
    the real estate industry specifically and in other industries generally;
and                                                                 

 - performed such other studies and analyses as it considered appropriate.

Goldman Sachs relied upon the accuracy and completeness of all of the   
financial and other information reviewed by it and assumed such accuracy and    
completeness for purposes of rendering its opinion. In addition, Goldman Sachs  
did not make an independent evaluation or appraisal of the assets and           
liabilities of Weeks or Duke or any of their respective subsidiaries and was not
furnished with any such evaluation or appraisal. The advisory services and      
opinion of Goldman Sachs referred to herein were provided for the information   
and assistance of the board of directors of Weeks in connection with its        
consideration of the transaction contemplated by the merger agreement and such  
opinion does not constitute a recommendation as to how any holder of the        
outstanding shares of Weeks common shares should vote with respect to the such  
transaction.                                                                    

The following is a summary of the material financial analyses used by   
Goldman Sachs in connection with providing its oral opinion to Weeks' board of

  Goldman Sachs also calculated and compared various financial multiples and
ratios based on information it obtained from SEC filings and Institutional      
Brokers Estimate System estimates. The multiples and ratios for Weeks were      
calculated using a price of $27.00 per share, the closing price of Weeks common 
shares on the NYSE on February 25, 1999. The multiples for Duke were calculated 
using a price of $21.88 per share, the closing price of Duke common shares on   
the NYSE on February 25, 1999. The multiples and ratios for Weeks and Duke were 
based on information provided by their respective managements and Institutional 
Brokers Estimate System estimates. The multiples for each of the selected       
companies were based on the most recent publicly available information. Goldman 
Sachs' analyses of the selected companies compared the following to the results 
for Weeks and Duke:

  (IV) CONTRIBUTION ANALYSIS.  Goldman Sachs reviewed certain historical and
estimated future operating and financial information for Weeks, Duke and the    
combined company resulting from the merger based on Weeks' and Duke's           
managements' consensus financial forecasts for each of Weeks, Duke and the      
combined entity. The analysis indicated that the Weeks shareholders would       
receive 25.9% of the outstanding common equity of the combined company after the
merger (on a fully diluted basis, assuming the conversion of all OP units and   
convertible preferred stock). Goldman Sachs also analyzed:                      

- earnings before interest, income taxes, depreciation and amortization 
based on actual 1998 and estimated years 1999 and 2000 adjusted to  
eliminate the effect of leverage;                                   

 - Funds from Operations based on actual 1998 and estimated years 1999 and
2000; and                                                           

   - funds available for distribution based on actual 1998 and estimated years
1999 and 2000.                                                      

 These analyses indicated the following contributions by Weeks and Duke to
the combined company for the following periods and implied exchange ratios based
on such contributions:

    (V) PRO FORMA MERGER ANALYSES.  Goldman Sachs prepared pro forma analyses of
the financial impact of the transaction using (a) management estimates for Weeks
and Duke and (b) the estimates of the Goldman Sachs research department for     
street consensus estimates. For each of the estimated years 1999 and 2000,      
Goldman Sachs compared the Funds from Operations of Duke common shares, on a    
stand-alone basis, to the Funds from Operations of the common shares of the     
combined company on a pro forma basis. Goldman Sachs performed this analysis    
based on the closing price for Duke and Weeks on February 26, 1999 and assuming 
a 1.38 exchange ratio on Duke's closing price of February 26, 1999. Based on    
such analyses and assuming transaction costs for the street consensus estimates 
analysis and transaction costs, additional interest savings, general and        
administrative synergies, and interest expenses that might result from the      
merger for the management estimates analysis, the proposed transaction would be 
accretive to Duke Funds from Operations in both of the above scenarios.         

   (VI) NET ASSET VALUE ANALYSIS.  Goldman Sachs estimated the net asset value
per share for Weeks' common shares as of year-end 1999 by subtracting           
outstanding debt and other liabilities from gross value, where gross

$122.7 million at capitalization rates ranging from 8.75% to 9.25% plus the     
estimated year-end 1999 value of other assets.                                  

   These analyses indicated the following estimated net asset values of Weeks'
common shares:

The preparation of a fairness opinion is a complex process and is not   
necessarily susceptible to partial analysis or summary description. Selecting   
portions of the analyses or of the summary set forth above, without considering 
the analyses as a whole, could create an incomplete view of the processes       
underlying Goldman Sachs' opinion. In arriving at its fairness determination,   
Goldman Sachs considered the results of all such analyses. No company or        
transaction used in the above analyses as a comparison is directly comparable to
Weeks or Duke or the contemplated transaction.                                  

    The analyses were prepared for purposes of providing an opinion to the Weeks
Board of Directors as to the fairness from a financial point of view of the     
exchange ratio pursuant to the merger agreement to the holders of the           
outstanding Weeks common shares. The analyses do not purport to be appraisals or
necessarily reflect the prices at which businesses or securities actually may be
sold. Analyses based upon forecasts of future results are not necessarily       
indicative of actual future results, which may be significantly more or less    
favorable than suggested by such analyses. Because such analyses are inherently 
subject to uncertainty, being based upon numerous factors or events beyond the  
control of the parties or their respective advisors, none of Weeks, Duke,       
Goldman Sachs or any other person assumes responsibility if future results are  
materially different from those forecast.                                       

As described above, Goldman Sachs' opinion to the Board of Directors of 
Weeks was one of many factors taken into consideration by the Weeks Board of    
Directors in making its determination to approve the merger agreement. The      
foregoing summary does not purport to be a complete description of the analyses 
performed by Goldman Sachs.                                                     

 Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with  
mergers and acquisitions, negotiated underwritings, competitive biddings,       
secondary distributions of listed and unlisted securities, private placements,  
and valuations for estate, corporate and other purposes. Goldman Sachs is       
familiar with Weeks, having provided certain investment banking services to     
Weeks from time to time, including having acted as:                             

- lead-managing underwriter of a public offering of 2.25 million Weeks  
common shares in November 1996;                                     

    - lead-managing underwriter of a public offering of 3.2 million Weeks common
shares in May 1997;                                                 

 - lead-managing underwriter of a public offering of $150 million Series A
Cumulative Redeemable Preferred shares of Weeks in October 1997;    

- lead-managing underwriter of a public offering of $100 million 6.875% 
Notes due 2005 of Weeks in March 1998;                              

- lead-managing underwriter of a public offering of $100 million 7.375% 
Notes due 2007 of Weeks in July 1998; and                           

- its financial advisor in connection with, and having participated in  
certain of the negotiations leading to, the merger agreement.

   Goldman Sachs has also provided certain investment banking services to Duke
from time to time, including having acted as:                                   

 - lead-managing underwriter of a public offering of $100 million Puttable
Reset Securities PURS(SM) due 2016 of Duke in March 1998; and       

    - sole underwriter of a public offering of 1.5 million shares of Duke common
shares in November 1998.                                            

 Goldman Sachs may also provide investment banking services to Duke in the
future. Weeks selected Goldman Sachs as its financial advisor because it is a   
nationally recognized investment banking firm that has substantial experience in
transactions similar to the merger.                                             

Goldman Sachs provides a full range of financial, advisory and brokerage
services and in the course of its normal trading activities may from time to    
time effect transactions and hold positions in the securities or options on     
securities of Weeks and/or Duke for its own account and for the account of      
customers.                                                                      

Pursuant to a letter agreement dated February 23, 1999, Weeks engaged   
Goldman Sachs to act as its financial advisor in connection with the possible   
sale of, or merger involving, all or a portion of the common shares or assets of
Weeks. Pursuant to the terms of this letter, Weeks has agreed to pay Goldman    
Sachs a transaction fee of 0.35% of the aggregate consideration paid in the     
merger.                                                                         

    Weeks has agreed to reimburse Goldman Sachs for its reasonable out-of-pocket
expenses, including attorneys' fees, and to indemnify Goldman Sachs against     
certain liabilities, including certain liabilities under the federal securities 
laws.                                                                           

INTERESTS OF WEEKS DIRECTORS, OFFICERS AND SIGNIFICANT SHAREHOLDERS             

The merger will qualify as a change of control for purposes of existing 
change of control agreements between Weeks and certain members of its           
management. Under these agreements, which will be assumed by Duke in the merger,
11 Weeks officers are entitled to receive severance payments based upon a       
multiple of such officer's then current compensation upon the occurrence of     
certain events, including the following: (1) if the officer's employment is     
terminated without cause within 24 months following a change of control or (2)  
if the officer voluntarily terminates his employment for good reason within the 
12 month period ending on the second anniversary of the change of control. In   
addition, the change of control agreements entered into with each of Messrs.    
Weeks, Senkbeil, Robinson, Stockert and Nelley, entitle these officers to       
receive the severance benefit if they voluntarily terminate their employment    
before the first anniversary of the change of control. In connection with the   
merger, these officers have agreed in side letter agreements with Duke to waive 
their right to this severance benefit if they voluntarily terminate their       
employment, except that Mr. Stockert will be entitled to receive the severance  
benefit he is entitled to under his change of control agreement if he           
voluntarily terminates his employment during the four month period beginning on 
the first anniversary of the effective time of the merger. Duke also agreed to  
extend the period for which Messrs. Weeks, Senkbeil, Robinson, Stockert and     
Nelley may receive severance for termination by Duke-Weeks other than for cause 
or voluntary termination of their employment for good reason from a 12 month    
period ending on the second anniversary of the effective date of the merger to a
24 month period ending on the third anniversary of the effective date of the    
merger.                                                                         

In order to induce Mr. Robinson to waive his rights under his change of 
control agreement, Duke agreed to provide him with a $250,000 unsecured loan    
which will be payable in equal installments over a five year period to          
facilitate his relocation to Florida. The terms of the loan provide that (1) the
annual payment of principal will be forgiven if Mr. Robinson is employed by     
Duke-Weeks or an affiliate of Duke-Weeks at the due date of such payment; and   
(2) the principal and interest will be forgiven in full if (x) Duke-Weeks       
terminates his employment other than for cause, (y) Mr. Robinson voluntarily    
terminates his own employment for good reason within the 12 month period        
following the effective time of the merger, or (z) Duke changes the terms of the
agreement made with Mr. Robinson regarding modifications to his rights under his
change of control agreement without his prior consent before the first          
anniversary of the merger.

 All of the Weeks outstanding stock options, including the 915,600 held by
directors and executive officers of Weeks will be converted into options to     
purchase Duke common shares and will (1) maintain their current vesting         
schedules and (2) have an exercise price adjusted for the merger exchange ratio.
The 32,309 shares of unvested Weeks restricted stock will become 44,586 shares  
of Duke restricted stock, based on the merger exchange ratio, and will become   
subject to forfeiture to the same extent as shares of Weeks restricted stock are
currently subject to forfeiture.                                                

If the merger is approved, the Weeks directors that become non-employee 
Duke-Weeks directors, will be eligible to receive 300 common shares of Duke     
pursuant to the 1996 Duke Directors' Stock Payment Plan for each fiscal quarter 
of service as a director (or a pro-rata amount for less than a full fiscal      
quarter), the first distribution of such shares to occur at the end of the first
fiscal quarter in which the former Weeks director serves as a Duke-Weeks        
director. In addition, if the 1999 Duke Directors' Stock Option and Dividend    
Increase Unit Plan is approved by the shareholders of Duke, Weeks' directors    
that become Duke-Weeks directors and are ineligible to receive stock option     
grants under any other Duke plan for a given calendar year, will be granted     
options to purchase 2,500 common shares of Duke for such calendar year, the     
initial grant of such options for the former Weeks directors to occur at the    
first quarterly meeting of Duke's compensation committee for the year 2000.     

   Following the execution of the merger agreement, Weeks reached an agreement
in principle, subject to final documentation, with Harold S. Lichtin, who       
currently serves on the Weeks Board, regarding Mr. Lichtin's relationship with  
Duke-Weeks following the merger. This agreement in principle contains the       
following material terms:                                                       

   - Mr. Lichtin will resign from the Weeks Board on the effective date of the
merger and will not serve on the Board of Directors of the combined 
company;                                                            

    - Mr. Lichtin's employment under the Consulting Agreement dated December 30,
    1997, between Mr. Lichtin and Weeks will terminate on the effective date
of the merger, and Mr. Lichtin will not be entitled to receive any  
    additional compensation or benefits pursuant to the Consulting Agreement
following the merger;                                               

- The restriction on transferability of Weeks OP common units and Weeks 
   common shares held by Mr. Lichtin and his affiliates and on exercise of
      the right to exchange such units for Weeks common shares will terminate on
      the effective date of the merger. Restrictions relating to Weeks OP common
   units to be issued to Mr. Lichtin and his affiliates in connection with
    future contributions of additional properties will remain subject to the
restrictions provided for in the existing documents governing such  
contributions;                                                      

    - Mr. Lichtin will be released from certain provisions of his Noncompetition
Agreement with Weeks, and will be permitted to engage in competing  
businesses in Weeks' markets following the effective

  date of the merger; PROVIDED, that Mr. Lichtin will be prohibited from
   soliciting existing employees and customers of Weeks until December 31,
2000; and                                                           

- Weeks has agreed to release its security interest in certain Weeks OP 
    common partnership units held by Mr. Lichtin and his affiliates securing
their indemnification obligations under the Weeks OP partnership    
   agreement. Notwithstanding this release, Mr. Lichtin and his affiliates
remain liable for such obligations until the end of the applicable  
  survival period provided for under the Weeks OP partnership agreement.

SERVICE COMPANIES OPTION                                                        

A. Ray Weeks, Jr., Thomas D. Senkbeil and Forrest W. Robinson are the   
holders of common shares of Weeks' third-party service subsidiaries, Weeks      
Construction Services and Weeks Realty Services, representing 99% of the voting 
power and 1% of the economic interests in those companies. Contemporaneously    
with the execution and delivery of the merger agreement, MWSB, Inc., a newly    
formed corporation owned by Messrs. Hefner, Zink, Weeks and Senkbeil, entered   
into an option agreement with each of Messrs. Weeks, Senkbeil and Robinson which
grants MWSB, Inc. an option to purchase all their shares in Weeks Construction  
Services and Weeks Realty Services at any time after the effective date of the  
merger. The total exercise price for the option to purchase both Weeks services 
entities is $110,000 (as adjusted for any additional capital contributed to the 
service entities prior to the exercise of such option).                         

    In addition, prior to the effective time of the merger, MWSB, Inc. will also
enter into an agreement which grants MWSB, Inc. an option to purchase common    
shares of Weeks HVAC, Inc., from Messrs. Weeks, Senkbeil, Robinson, Duckett,    
Cutlip, Flowers and Simpson for an aggregate exercise price of $20,000. Weeks   
HVAC, Inc. provides HVAC services for tenants in Weeks' existing properties and 
for third parties. The shares of Weeks HVAC, Inc. that are subject to the option
represent 100% of Weeks HVAC Inc.'s voting power and 100% of its economic       
interests.                                                                      

VOTING AGREEMENTS                                                               

  Contemporaneously with the execution and delivery of the merger agreement,
(1) holders of approximately 2% of Weeks' outstanding common shares and holders 
of approximately 56% of the outstanding limited partnership interests in Weeks  
OP (other than those held indirectly by Weeks, which are not entitled to vote)  
entered into voting agreements with Duke and Duke OP pursuant to which, among   
other things, those holders have granted to Duke irrevocable proxies to vote    
their shares and partnership interests in favor of the merger and the merger    
agreement and the other transactions contemplated thereby and against any       
competing proposal, and (2) holders of approximately 5% of Duke's outstanding   
common shares and holders of approximately 95% of the outstanding limited       
partnership interests in Duke OP entered into voting agreements with Weeks and  
Weeks OP, pursuant to which, among other things, those holders have granted to  
Weeks irrevocable proxies to vote their shares and partnership interests in     
favor of the merger agreement and the other transactions contemplated thereby   
and against any competing proposal.                                             

    The voting agreements terminate upon the termination of the merger agreement
or the consummation of the transactions contemplated thereby.                   

MATERIAL FEDERAL INCOME TAX CONSEQUENCES                                        

The following discussion summarizes the material federal income tax     
consequences relating to the merger of Weeks into Duke. This discussion is not  
exhaustive of all possible tax considerations and does not include a detailed   
discussion of any state, local or foreign tax considerations. In addition, the  
following discussion is intended to address only those federal income tax       
considerations that are generally applicable to all U.S. shareholders and does  
not discuss all of the aspects of federal income taxation that may be relevant  
to particular U.S. shareholders in light of their specific circumstances or to  
certain types of shareholders (including insurance companies, tax-exempt        
entities, financial institutions or broker-dealers,

foreign corporations and persons who are not citizens or residents of the United
States) who are subject to special treatment under the federal income tax laws. 

The statements and opinions in this discussion are based on current     
provisions of the Internal Revenue Code of 1986, as amended (the "Code"), and   
its legislative history, existing, temporary and currently proposed Treasury    
Regulations under the Code, existing administrative rulings and practices of the
Internal Revenue Service and judicial decisions. No assurance can be given that 
legislative, judicial or administrative changes will not affect the accuracy of 
any statements in this joint proxy statement and prospectus with respect to     
transactions entered into or contemplated prior to the effective date of such   
changes. In addition, Duke has not requested and does not plan to request any   
rulings from the Internal Revenue Service concerning the tax treatment of the   
merger. Accordingly, no assurance can be given that the statements set forth in 
this section (which do not bind the Internal Revenue Service or the courts) will
not be challenged by the Internal Revenue Service or sustained by the courts if 
so challenged.                                                                  

 THIS DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING.
EACH HOLDER OF DUKE OR WEEKS SHARES IS URGED TO CONSULT WITH HIS OR HER OWN TAX 
ADVISOR REGARDING THE SPECIFIC TAX CONSEQUENCES TO HIM OR HER OF THE MERGER,    
INCLUDING THE FEDERAL, STATE, LOCAL, AND FOREIGN TAX CONSEQUENCES THAT MAY BE   
APPLICABLE TO SUCH HOLDER.                                                      

TAX CONSEQUENCES OF THE MERGER.  The merger is intended to qualify as a 
reorganization under Section 368(a) of the Code. Rogers & Wells LLP, counsel to 
Duke, and King & Spalding, counsel to Weeks, as a condition to the merger, will 
deliver opinions to Duke and Weeks, respectively, that the merger will qualify  
as a reorganization under the provisions of Section 368(a) of the Code, based on
certain factual assumptions and representations made by Duke and Weeks.         

If the merger qualifies as a reorganization under Section 368(a) of the 
Code, a Weeks shareholder who receives solely Duke common shares in exchange for
Weeks common shares will not recognize any gain or loss on the exchange.        
Similarly, a Weeks shareholder who receives solely Duke preference shares in    
exchange for Weeks preferred shares will not recognize any gain or loss on the  
exchange. However, if a Weeks shareholder receives Duke common shares and cash  
in lieu of a fractional share of Duke common shares, such Weeks shareholder will
recognize taxable gain or loss in an amount equal to the difference between such
cash and the tax basis allocated to such Weeks shareholder's fractional share   
interest in Duke common shares. Such gain or loss will constitute capital gain  
or loss if the shareholder's Weeks common shares were held as a capital asset. A
Weeks shareholder will have an aggregate tax basis in the Duke shares received  
in the merger equal to his aggregate tax basis in the Weeks shares (reduced by  
the amount of any tax basis allocable to a fractional share interest for which  
cash is received) that were exchanged for those Duke shares. A Weeks            
shareholder's holding period for Duke shares received in the merger will include
his holding period for the Weeks shares that were exchanged for those Duke      
shares, if the Weeks shares are held as a capital asset by the Weeks shareholder
at the effective time of the merger. If a Weeks shareholder holds multiple      
blocks of Weeks shares that have different holdings periods and/or different tax
bases, the Duke shares received for each block of Weeks shares will have a      
separate tax basis and holding period that is determined by reference to the    
specific tax basis and holding period of the specific Weeks shares exchanged for
those Duke shares.                                                              

No gain or loss will be recognized by Duke or Weeks as a result of the  
merger so long as the merger qualifies as a reorganization under Section 368(a) 
of the Code.                                                                    

PRE-MERGER DISTRIBUTIONS.  The merger agreement provides that Weeks will
distribute to its shareholders immediately prior to the merger the minimum      
amount necessary for Weeks to satisfy the REIT distribution requirements under  
Section 857(a)(1) of the Code for Weeks' short taxable year ending at the       
effective time. The merger agreement also provides that, should such            
distribution by Weeks occur, Duke will distribute to its shareholders an amount 
per share equal to the amount per share of any such dividend paid by Weeks,     
adjusted to reflect the exchange ratio of Weeks shares for Duke shares in the   
merger. Any such distributions by Weeks and Duke are referred to in this        
discussion as "pre-merger distributions." Except as described below with respect
to pre-merger distributions that may be designated as capital gain

dividends, (1) pre-merger distributions paid to Weeks' taxable U.S. shareholders
out of Weeks' current or accumulated earnings and profits would be taken into   
account by those shareholders as ordinary income and would not be eligible for  
the dividends received deduction generally available for corporations, and (2)  
any pre-merger distributions paid to Duke's taxable U.S. shareholders out of    
Duke's current or accumulated earnings and profits would be taken into account  
by those shareholders as ordinary income and would not be eligible for the      
dividends received deduction generally available for corporations. Any          
pre-merger distributions in excess of current and accumulated earnings and      
profits of either Weeks (in the case of any Weeks pre-merger distribution) or   
Duke (in the case of any Duke pre-merger distribution) would not be taxable to  
shareholders to the extent the distribution does not exceed the adjusted basis  
of the shareholder's shares with respect to which the distribution is made, but 
rather would reduce the adjusted basis of those shares. To the extent any such  
pre-merger distribution in excess of earnings and profits exceeded the adjusted 
basis of a shareholder's shares, the distribution would be included in the      
shareholder's income as capital gain (such capital gain will be long-term       
capital gain if the shares have been held for more than one year or short-term  
capital gain if the shares have been held for one year or less), assuming the   
shareholder holds the shares as a capital asset at the time of the merger. Any  
pre-merger distributions designated as capital gain dividends will be taxed as  
capital gain (to the extent they do not exceed the payor's actual net capital   
gain for the taxable year), provided that corporate shareholders may be required
to treat up to 20% of certain capital gain distributions as ordinary income.    

 BACKUP WITHHOLDING AND INFORMATION REPORTING.  The cash payments, if any,
due a holder upon the exchange of Weeks common shares pursuant to the merger,   
other than exempt persons or entities, will be subject to "backup withholding"  
for federal income tax purposes unless specific requirements are met. Duke or a 
third-party paying agent, as the case may be, must withhold 31% of the cash     
payments to the holder, unless the holder (1) is a corporation or comes within  
certain other exempt categories and, when required, demonstrates this fact or   
(2) provides a taxpayer identification number, certifies as to no loss of       
exemption and otherwise complies with the applicable requirements of the backup 
withholding rules. Any amount paid as backup withholding will be credited       
against the holder's federal income tax liability.                              

Holders who receive Duke shares must also comply with the information   
reporting requirements of the Treasury Regulations under Section 368 of the     
Code. In general, these Treasury Regulations require any taxpayer who receives  
shares, securities or other property, including cash, in a tax-free exchange in 
connection with a corporate reorganization to include with his or her income tax
return a complete statement of facts pertaining to the nonrecognition of gain or
loss including (1) the cost or other basis of the shares or securities          
transferred in the exchange, and (2) the amount of shares, securities or other  
property received in the exchange. In addition, the statement must include the  
fair market value, at the date of the exchange, of each type of shares,         
securities or other property received by the taxpayer and taxpayers are required
to keep permanent records showing the cost or other basis of any property       
involved in such an exchange. All Duke and Weeks shareholders are urged to      
consult their own tax advisors to determine the specific information that they  
may need to file pursuant to the Treasury Regulations under Section 368 of the  
Code.                                                                           

CONSEQUENCES OF THE MERGER ON DUKE'S QUALIFICATION AS A REAL ESTATE     
INVESTMENT TRUST. In the opinion of Rogers & Wells LLP, Duke was organized and  
has operated in conformity with the requirements for qualification and taxation 
as a real estate investment trust under the Code commencing with its taxable    
year ended December 31, 1993, and Duke's current and proposed method of         
operation, taking into account the effects of the merger, will enable it to     
continue to meet the requirements for qualification and taxation as a real      
estate investment trust under the Code. The opinion of Rogers & Wells LLP is    
based on (1) certain factual representations of Duke and Weeks, (2) the         
assumption that Duke was organized and has operated in conformity with the      
requirements for qualification and taxation as a real estate investment trust   
under the Code for all of its taxable years ending prior to December 31, 1993,  
and (3) the opinion of King & Spalding that Weeks was organized and has operated
in conformity with the requirements for qualification and taxation as a real    
estate investment trust under the Code commencing with its taxable year ended   
December 31, 1994, and the current organization and method of operation of Weeks
will allow

it to continue to qualify as a real estate investment trust through the         
effective time. Although Duke intends to operate in a manner which will permit  
it to continue to satisfy the requirements for qualification and taxation as a  
real estate investment trust under the Code, no assurance can be given that     
these requirements will be met.                                                 

 The continued qualification of Duke-Weeks as a REIT will also depend upon
the continued classification of Duke OP as a partnership for federal income tax 
purposes and not as an association taxable as a corporation or a "publicly      
traded partnership" taxable as a corporation. A publicly traded partnership will
not be treated as a corporation as long as 90% or more of its gross income is   
"qualifying income" within the meaning of the Code. Qualifying income is        
generally defined to include, among other items, interest, real property rents  
and gain from the disposition of real property. In the opinion of Rogers & Wells
LLP, Duke OP, commencing with its first taxable year ended December 31, 1993,   
has been properly classified as a partnership for federal income tax purposes   
and not as an association taxable as a corporation or as a publicly traded      
partnership taxable as a corporation, and Duke OP's proposed method of          
operation, taking into account the effects of the merger, will enable it to     
continue to be treated as a partnership for federal income tax purposes. The    
opinion of Rogers & Wells LLP is based on (1) certain factual representations of
Duke and Weeks including representations regarding the sources of income of Duke
OP and Weeks OP, and (2) the opinion of King & Spalding that Weeks OP,          
commencing with its taxable year ended December 31, 1994 and through the        
effective time, has been properly classified as a partnership for federal income
tax purposes and not as an association taxable as a corporation or as a publicly
traded partnership taxable as a corporation.                                    

    In order to qualify as a REIT, the combined company may not own (1) the debt
or equity securities of a single issuer (other than a mortgage loan which       
qualifies as a real estate asset, an interest in a partnership or shares of a   
"qualified REIT subsidiary" or another REIT) with a value in excess of 5% of the
value of the combined company's total assets, and (2) more than 10% of any      
single issuer's outstanding voting securities (other than an interest in a      
partnership or shares of a "qualified REIT subsidiary" or another REIT).        
Following the merger, Duke OP will directly own (x) approximately 95.9% of the  
non-voting common stock and 100% of the non-voting preferred stock of Duke      
Realty Construction, Inc., (y) 100% of the non-voting stock and 1% of the voting
stock of Weeks Construction Services and (z) 100% of the non-voting stock and 1%
of the voting stock of Weeks Realty Services (collectively referred to herein as
the "Service Companies"). By virtue of its ownership interest in Duke OP, the   
combined company will be considered to own its pro rata share of the assets of  
Duke OP, including the debt or equity securities of the Service Companies. Duke 
OP will not own more than 10% of the voting securities of any of the Service    
Companies and, therefore, the combined company will not own more than 10% of the
voting securities of any of the Service Companies. In addition, Duke's and      
Weeks' senior management believe that the combined company's pro rata share of  
the value of the debt or equity securities of each of the Service Companies will
not exceed 5% of the total value of the combined company's assets after the     
merger. Management's belief is based in part upon its analysis of the           
anticipated operating cash flows of the Service Companies. There can be no      
assurance, however, that the IRS will not contend that the value of the         
securities of a particular Service Company exceeds the 5% value limitation.     
Rogers & Wells LLP, in rendering its opinion regarding the qualification of     
Duke-Weeks as a REIT, will rely on the conclusions of Duke-Weeks and its senior 
management as to the value of the securities of the Service Companies.          

ACCOUNTING TREATMENT                                                            

    Duke will account for the merger as a purchase in accordance with Accounting
Principals Board Opinion No. 16. Accordingly, Duke will record the assets and   
liabilities acquired from Weeks at Duke's cost, the consideration paid to Weeks 
shareholders in the merger.                                                     

APPRAISAL RIGHTS                                                                

    Because the Weeks common shares and the Duke common shares are listed on the
New York Stock Exchange and the preference shares of Duke into which the Weeks  
preferred shares will be converted will also be listed on the New York Stock    
Exchange, neither Weeks shareholders nor Duke shareholders have appraisal rights
under Georgia or Indiana law.

THE MERGER AGREEMENT

  WE ENCOURAGE YOU TO READ THE ENTIRE MERGER AGREEMENT, WHICH IS ATTACHED AS
ANNEX A TO THIS JOINT PROXY STATEMENT AND PROSPECTUS.                           

GENERAL                                                                         

 The merger agreement provides for the merger of Weeks with and into Duke.

In the merger, the holders of Weeks common shares will receive for each 
Weeks common share the right to receive 1.38 Duke common shares. Holders of     
Weeks 8.0% Series A cumulative redeemable preferred shares, par value $.01 per  
share, will be converted into the right to receive one preference share of Duke 
representing 1/1,000 of an 8.0% Series F cumulative redeemable preferred share  
of Duke. Holders of Weeks 8.625% Series D cumulative redeemable preferred       
shares, par value $.01 per share, will be converted into the right to receive   
one preference share of Duke representing 1/1,000 of an 8.625% Series H         
cumulative redeemable preferred share of Duke. The Duke preference shares to be 
issued in the merger will have rights and preferences substantially identical to
the rights and preferences of the Weeks Series A preferred shares and Weeks     
Series D preferred shares.                                                      

Concurrently with the execution of the merger agreement, Duke OP, Duke's
principal operating partnership subsidiary, entered into a merger agreement with
Weeks OP, Weeks' principal operating partnership subsidiary. In the operating   
partnership merger or "OP" merger, the holders of common units of limited       
partnership interest in Weeks OP will be converted into 1.38 common units of    
limited partnership interest in Duke OP, each 8.0% Series A cumulative          
redeemable preferred partnership unit in Weeks OP will be converted into one    
8.0% Series F cumulative redeemable preferred unit in Duke OP, each 8.0% Series 
C cumulative redeemable preferred partnership unit in Weeks OP will be converted
into one 8.0% Series G cumulative redeemable preferred unit in Duke OP and each 
8.625% Series D cumulative redeemable preferred partnership unit in Weeks OP    
will be converted into one 8.625% Series H cumulative redeemable preferred unit 
in Duke OP. In the OP merger, all Weeks OP units will cease to be outstanding   
and will automatically be cancelled and retired and all rights with respect to  
the Weeks OP units will cease to exist.                                         

No certificates or script representing fractional shares of Duke common 
shares will be issued upon surrender for exchange of Weeks certificates. Cash   
will be issued in lieu of fractional shares of Duke common shares upon surrender
of such certificate, and any dividends or other distributions to which such     
holder is entitled, in each case without interest and less any required         
withholding taxes.                                                              

The merger of Duke and Weeks is intended to qualify as a tax-free       
reorganization for federal income tax purposes, and the OP merger transaction is
intended to qualify as a tax-deferred exchange for Weeks and the other holders  
of Weeks OP units. The discussion in this joint proxy statement and prospectus  
of the merger agreement and the description of the material terms of the merger 
agreement are qualified in their entirety by reference to the merger agreement, 
a copy of which is attached to this joint proxy statement and prospectus as     
Annex A and is incorporated herein by reference.                                

EXPENSES OF SOLICITATION                                                        

  All fees and expenses, including financial advisory and other professional
services fees, incurred in connection with the merger agreement and the         
transactions contemplated thereby will be paid by the party incurring the       
expenses, except for fees and expenses incurred in connection with filing,      
printing and distributing this joint proxy statement and prospectus, which will 
be shared equally by Duke and Weeks. The costs of solicitation of proxies from  
Duke shareholders will be borne by Duke. The costs of solicitation of proxies   
from Weeks shareholders will be borne by Weeks. Duke and Weeks will reimburse   
brokers, fiduciaries, custodians and other nominees for reasonable out-of-pocket
expenses incurred in sending this joint proxy statement and prospectus and other
proxy materials to, and obtaining instructions relating to

such material from, Duke and Weeks shareholders. Duke shareholder proxies may be
solicited by directors or officers of Duke in person, by telephone, telegraph,  
facsimile or other appropriate means of communication. Weeks shareholder proxies
may be solicited by directors or officers of Weeks in person, by telephone,     
telegraph, facsimile or other appropriate means of communication. In addition,  
Duke will retain Innisfree M&A Incorporated to assist in the solicitation of    
proxies and expects that the estimated fees for services to Duke will not exceed
$15,000 in the aggregate plus expenses. Weeks will retain Innisfree M&A         
Incorporated to assist in the solicitation of proxies and expects that the      
estimated fees for these services will not exceed $5,000 in the aggregate plus  
expenses.                                                                       

   Duke and Weeks will also reimburse custodians, nominees and fiduciaries for
forwarding proxies and proxy materials to the beneficial owners of its shares in
accordance with regulations of the SEC and the NYSE.                            

EFFECTIVE TIME OF THE MERGER                                                    

    Subject to the satisfaction, or waiver, of the conditions to the obligations
of Duke and Weeks to complete the merger, the merger will be completed as soon  
as practicable following the approval by the shareholders of Duke and Weeks of  
the merger and the merger agreement at their respective meetings, but no sooner 
than one business day after the completion of the OP merger.                    

EXCHANGE OF WEEKS SHARES                                                        

As of the effective time of the merger, Duke will deposit certificates  
representing the Duke common shares, Duke Series F preference shares and Duke   
Series H preference shares, if any, to be issued in exchange for outstanding    
Weeks common shares, Weeks Series A preferred shares and any Weeks Series D     
preferred shares with an exchange agent designated by Duke and reasonably       
acceptable to Weeks. Duke will also deposit cash with the exchange agent to be  
paid in lieu of the issuance of fractional Duke common shares. The deposit of   
the certificates and cash in lieu of fractional shares will be for the benefit  
of the holders of Weeks common shares, Weeks Series A preferred shares and Weeks
Series D preferred shares, as applicable, for exchange in accordance with the   
merger agreement.                                                               

As soon as reasonably practicable after the effective time, the exchange
agent will mail to each holder of record of a Weeks stock certificate or        
certificates whose shares were converted into the right to receive Duke shares  
in the merger and which, prior to the effective time, represented outstanding   
shares of Weeks common shares, Weeks Series A preferred shares or Weeks Series D
preferred shares, a letter of transmittal which will specify that delivery will 
be effected and risk of loss and title to the certificates will pass only upon  
delivery of the Weeks certificates to the exchange agent; and instructions for  
surrendering the Weeks certificates in exchange for certificates representing   
Duke common or preference shares.                                               

Upon surrender of a Weeks certificate for cancellation to the exchange  
agent, together with the letter of transmittal, duly executed, and any other    
documents reasonably required by the exchange agent, the holder of a Weeks      
certificate formerly representing shares of Weeks common or preferred shares    
will be entitled to receive in exchange a certificate representing that number  
of Duke common or preference shares which such holder has the right to receive  
pursuant to the merger agreement, and any unpaid Duke distributions with a      
record date after the time that the merger becomes effective that the holder has
the right to receive. The surrendered Weeks certificates will be cancelled.     

In the event that the ownership of Weeks common or preferred shares is  
transferred and the transfer is not registered in Weeks' transfer records, a    
certificate representing the appropriate number of Duke common or preference    
shares may be made to a person other than the person in whose name the          
surrendered certificate is registered if the certificate is properly endorsed or
is in proper form for transfer and is accompanied by all documents required to  
evidence and effect a transfer and by evidence that any applicable stock        
transfer taxes have been paid. After the effective time, each Weeks certificate 
will

represent only the right to receive, upon surrender, Duke common or preference  
shares without interest, and dividends or other distributions to which the      
holder is entitled.                                                             

 The exchange agent will not be entitled to vote or exercise any rights of
ownership with respect to Duke common or preference shares it holds, except that
it will receive and hold all dividends or other distributions paid or           
distributed with respect to the Duke shares for the account of persons entitled 
to them.                                                                        

UNCLAIMED MERGER CONSIDERATION                                                  

Any merger consideration which is delivered to the exchange agent and is
unclaimed for six months will be redelivered to Duke, and any holders of Weeks  
certificates will after that date only look to Duke for the merger              
consideration, subject to applicable abandoned property or similar laws.        

RECORD DATES; DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES                  

The merger agreement provides that Weeks may declare a dividend to the  
holders of Weeks common shares, the record date for which will be the close of  
business on the last business day prior to the effective time. If Weeks declares
a final dividend, it will notify Duke at least 10 days prior to the date of the 
Weeks meeting, and Duke will declare a dividend to holders of Duke common shares
of record at the close of business on the last business day prior to the        
effective time.                                                                 

CONDITIONS TO THE MERGER                                                        

 The respective obligations of Duke and Weeks to effect the merger and the
other transactions contemplated by the merger agreement are subject to the      
satisfaction or waiver of each of the following conditions at or prior to the   
effective time of the merger:                                                   

 - Each party will have performed in all material respects its obligations
     contained in the merger agreement required to be performed on or prior to
    the closing of the merger and the representations and warranties of each
     party shall be true and correct in all material respects on and as of the
date made and the date of the closing of the merger, in each case as
    evidenced by certificates signed by each party's chief executive officer
and chief financial officer;                                        

  - The shareholders of Duke and Weeks will have approved the merger and the
other matters contemplated by the merger agreement;                 

- The registration statement of which this joint proxy statement and    
   prospectus forms a part which has become effective under the Securities
    Act of 1933, will not be the subject of any proceeding by the Securities
and Exchange Commission seeking a stop order;                       

    - The New York Stock Exchange will have approved for listing the Duke common
  shares and Duke preference shares issued in the merger, and any shares
      issuable on conversion of Weeks OP units, in each case subject to official
notice of issuance;                                                 

- No temporary restraining order, preliminary or permanent injunction or
    other order issued by any court of competent jurisdiction or other legal
     restraint or prohibition preventing the consummation of the merger or the
    OP merger or any of the other transactions or agreements contemplated by
the merger agreement will be in effect;                             

  - All consents and waivers from third parties necessary in connection with
     the consummation of the merger and the OP merger will have been obtained,

  - each will use its commercially reasonable efforts to obtain all required
consents to the transactions contemplated by the merger agreement;  

- upon and after the effective time, the combined company will provide  
     benefits to former employees of Weeks and Weeks subsidiaries which are no
    less favorable in the aggregate to such employees than those provided to
similarly situated employees of Duke and Duke OP;                   

- as of the effective time, each outstanding Weeks stock option will be 
     assumed by Duke and will be deemed to constitute an option to acquire, on
   the same terms and conditions as were applicable under such Weeks stock
     option, the same number of Duke common shares as the holder of such Weeks
   stock option would have been entitled to receive pursuant to the merger
     had the holder exercised the Weeks stock option in full immediately prior
to the effective time, at a price per share equal to the aggregate  
      exercise price for the shares subject to the Weeks stock option divided by
      the number of full Duke common shares deemed to be purchasable pursuant to
   the Weeks stock option. Prior to the effective time, Weeks will use its
     commercially reasonable efforts to obtain any necessary consents and will
     make any amendments to and take any actions in respect of any Weeks stock
plans, Weeks stock options or restricted stock award to the extent  
 consents or amendments are necessary to give effect to the foregoing;

- at the effective time, Duke will assume the Weeks stock plans, and the

time, all the then outstanding "Rights" under its existing Rights   
      Agreement for cash pursuant to and in compliance with the Rights Agreement
      or (2) take such other action to terminate the Rights Agreement as of that
 time, as Weeks and Duke may mutually agree. Weeks will not redeem the
Rights issued under the Rights Agreement, or terminate the Rights   
     Agreement, prior to the effective time (other than in accordance with the
preceding sentence) unless required to do so by a court of competent
jurisdiction;

 common shares, Weeks common shares, Duke OP common units and Weeks OP
common units;                                                       

    - at the closing, Duke OP will amend the partnership agreement of Duke OP to
provide that (1) any former limited partners of Weeks OP, as well as
    current or future limited partners of Duke OP will be permitted to elect
     to become liable to Duke OP to restore a negative capital account balance
      upon the liquidation of the partner's interest in Duke OP, up to an agreed
    upon dollar amount, (2) Duke OP will use commercially reasonable efforts
      during the 10 year period following the effective date of the OP merger to
maintain an amount of "recourse" debt equal to or greater than the  
     aggregate amount of Duke OP recourse debt as to which one or more current
    or future partners have agreed, or will agree in the future, to bear the
economic risk of loss through deficit make-up obligations, indemnity
    agreements or otherwise (which will initially be limited to an aggregate
     of $100 million for former Weeks OP partners); (3) appropriate provisions
be made to replicate the terms of the outstanding Series A, C and D 
classes of preferred units of Weeks OP; (4) approval of the Asset   
      Committee of the Duke Board be required for a period of 10 years following
  the closing date of the OP merger, for any proposed sale (or series of

      properties acquired from Weeks OP; (7) Duke withdraw as general partner of
     Duke OP and be replaced by a wholly owned subsidiary of Duke; (8) Duke OP
units may be freely pledged without general partner consent; and (9)

    - Weeks and Duke will establish an interim transactions committee which will
   review and jointly evaluate acquisition, budget and capital improvement
activities of each of Weeks and Duke between the date of the merger 
agreement and the effective time.                                   

NO SOLICITATION OF TRANSACTIONS                                                 

   In the merger agreement, each of Duke and Weeks has agreed that it will not
directly or indirectly, through any representative, solicit, encourage or       
facilitate any inquiries or the making of any proposal or other action that     
constitutes, or may reasonably be expected to lead to (other than the           
transactions expressly provided for in the merger agreement):                   

    - any merger, consolidation, share exchange, business combination or similar
      transaction involving Duke (or any of its subsidiaries, including Duke OP)
      or Weeks (or any of its subsidiaries, including Weeks OP), as the case may
be;                                                                 

    - any sale, lease, exchange, mortgage, pledge, transfer or other disposition

   whole, or Weeks and its subsidiaries, taken as a whole, as the case may
be, in a single transaction or series of related transactions;      

- any tender offer or exchange offer for 20% or more of the outstanding 
     equity securities of Duke (or any of its subsidiaries, including Duke OP)
or Weeks (or any of its subsidiaries, including Weeks OP); or       

   - any public announcement of a proposal, plan or intention to do any of the
  foregoing or any agreement to engage in any of the foregoing, or enter
    into or maintain or continue discussions or negotiate with any person in
furtherance of such inquiries.                                      

 Duke and Weeks also agreed to notify the other in writing (as promptly as
practicable) of all of the relevant details relating to all inquiries and       
proposals of the types described above which it or any of its subsidiaries or   
any representative may receive and if the inquiry or proposal is in writing,    
each of Duke and Weeks is required to deliver to the other a copy of the inquiry
or proposal.                                                                    

  Notwithstanding the foregoing, however, each of Duke and Weeks may, to the
extent required by the fiduciary obligations of either the Duke Board or the    
Weeks Board: (1) disclose to its shareholders any information required to be    
disclosed under applicable law; (2) to the extent applicable, comply with Rule  
14e-2(a) promulgated under the Securities Exchange Act of 1934 with respect to a
competing transaction, (3) in response to an unsolicited request, participate in
discussions or negotiations with or furnish information with respect to it

(4) approve and recommend (and in connection therewith, withdraw or modify its  
approval of the merger) a Superior Competing Transaction or enter into an       
agreement with respect to a Superior Competing Transaction. A "Superior

approved the merger;                                                    

     (7) by Weeks or Duke (unless Duke is in breach of certain obligations
    under the merger agreement) if, upon a vote at a duly held Duke shareholders
meeting or any adjournment the Duke shareholders have not approved the  
merger;                                                                 

       (8) by Weeks, prior to the Weeks shareholders meeting and not less than
   30 days after the Weeks Board of Directors has withdrawn or modified in any
manner adverse to Duke or Duke OP its approval or recommendation of the 
   merger, the OP merger or the merger agreement or the OP merger agreement in
connection with, or approved or recommended, a Superior Competing       
Transaction;                                                            

        (9) by Duke, prior to the Duke shareholders meeting and not less than 30
days after the Duke Board of Directors has withdrawn or modified in any

Transaction;                                                            

      (10) by Duke, if (i) prior to the Weeks shareholders meeting the Weeks

     (11) by Weeks, if (i) prior to the Duke shareholders meeting the Duke
   Board of Directors or any committee has withdrawn or modified in any manner
adverse to Weeks its approval or recommendation of the merger or the OP 
 merger or the merger agreement or the OP Agreement in connection with, or
    approved or recommended, a Superior Competing Transaction, (ii) Duke or Duke
OP shall have entered into any agreement with respect to any competing  
transaction, or (iii) the Duke Board of Directors or any committee shall
have resolved to do any of the above.                                   

  If the merger agreement is terminated under the circumstances described in
paragraph 2 or 6 above, then Weeks will be obligated to reimburse Duke for      
expenses incurred by Duke in connection with the merger, up to a maximum amount 
of $5 million. If, within 12 months following any such termination, Weeks       
consummates a competing transaction or enters into a definitive agreement with  
regard to a competing transaction, then Weeks will also be obligated to pay Duke
a termination fee of $50 million, less the amount of any termination expenses   
previously reimbursed. If the merger agreement is terminated under the          
circumstances described in paragraph 8 or 10 above, then Weeks is obligated to  
pay Duke a termination fee of $50 million less the amount of any termination    
expenses previously reimbursed.                                                 

  If the merger agreement is terminated under the circumstances described in
paragraphs 3 or 7 above, then Duke will be obligated to reimburse Weeks for     
expenses incurred by Weeks in connection with the merger, up to a maximum amount
of $5 million. If within 12 months following any such termination, Duke         
consummates a competing transaction or enters into a definitive agreement with  
regard to a competing transaction, then Duke will also be obligated to pay Weeks
a termination fee of $50 million, less the amount of any termination expenses   
previously reimbursed. If the merger agreement is terminated under the          
circumstances described in paragraph 9 or 11 above, then Duke is obligated to   
pay Weeks a termination fee of $50 million less the amount of any termination   
expenses previously reimbursed.                                                 

In the event of termination of the merger agreement by either party, the
merger agreement will become void and have no effect except to the extent that  
such termination results from a willful breach by a party of any of its         
representations, warranties, covenants or agreements.                           

INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE                             

   Duke has agreed to indemnify and hold harmless each director and officer of
Weeks and any subsidiary of Weeks in connection with any threatened or actual   
claim, action or investigation arising out of the fact that such person is or   
was a director or officer of Weeks or any Weeks subsidiary at or prior to the   
effective time, including all indemnified liabilities based on, or arising out  
of, or pertaining to the merger agreement, the merger, the OP merger or the     
transactions contemplated by the merger agreement or the OP merger agreement.   

 In addition, Duke has agreed that at or prior to the effective time, Duke
will purchase directors' and officers' liability insurance "tail" policy        
coverage for Weeks' directors and executive officers for a period of six years, 
which will provide the directors and officers with coverage on substantially    
similar terms as currently provided by Weeks to such directors and officers for 
claims based on activity prior to the effective time; provided, however, that   
Duke will have no obligation to pay more than $250,000 in premiums for the      
coverage.                                                                       

AMENDMENT AND WAIVER                                                            

  The merger agreement may be amended by the parties in writing by action of
their respective Boards at any time before or after any shareholder approvals,  
the Weeks OP approvals and the Duke OP approvals are obtained and prior to the  
filing of the articles of merger for the merger with the Secretary of State of  
Indiana and the Secretary of State of Georgia and a certificate of merger for   
the OP merger with the Secretary of State of Indiana and the Secretary of State 
of Georgia; provided however that, after any of the stockholder approvals, the  
Weeks OP approvals and the Duke OP approvals are obtained, amendments,          
modifications or supplements must not alter the amount or change the form of the
consideration to be delivered to Weeks' or Duke's shareholders or alter or      
change any of the terms or conditions of the merger agreement if the alteration 
or change would adversely affect Weeks' shareholders or Duke's shareholders, or 
the Weeks limited partners or Duke limited partners.

COMPARISON OF SHAREHOLDER RIGHTS

The rights of Duke shareholders are currently governed by the Indiana   
Business Corporation Law (the "IBCL") and the Amended and Restated Articles of  
Incorporation and the Amended and Restated Bylaws of Duke (the "Duke Charter"   
and the "Duke Bylaws," respectively). The rights of Weeks shareholders are      
currently governed by the Georgia Business Corporation Code (the "GBCC") and the
Restated Articles of Incorporation and the Third Amended and Restated Bylaws of 
Weeks (the "Weeks Charter" and "Weeks Bylaws," respectively).                   

   The following discussions are not intended to be complete and are qualified
by reference to the IBCL, the GBCC, the Duke Charter, the Duke Bylaws, the Weeks
Charter and the Weeks Bylaws. Copies of the Duke Charter, the Duke Bylaws, the  
Weeks Charter and the Weeks Bylaws are incorporated by reference herein and will
be sent to holders of Duke shares and Weeks shares upon request. See "Where You 
Can Find More Information."                                                     

As part of the merger, Duke's name will be changed to Duke-Weeks Realty 
Corporation for two years after the merger and then to Duke Realty Corporation  
following that two year period, unless the combined company's Board of Directors
recommends against changing the name, and the total number of authorized common 
shares will be increased to 250,000,000.                                        

In addition, at the Duke annual meeting, shareholders will be asked to  
approve the following additional amendments to the Duke Charter:                

- increasing the maximum number of directors from 15 to 23;             

   - changing the existing requirement that 80% of the shares of CAPITAL STOCK
     of Duke approve certain amendments to Duke's Articles of Incorporation to
require the approval of 80% of the COMMON SHARES of Duke; and       

   - changing the existing requirement that 80% of the shares of capital stock
    approve any amendment to the provisions of the Articles of Incorporation
 relating to the number, classes, term of office and qualifications of
   directors to require the approval of a majority of the common shares of
Duke.                                                               

AUTHORIZED CAPITAL                                                              

  Duke is currently authorized to issue 155,000,000 shares of capital stock,
of which 150,000,000 are common shares and 5,000,000 are preferred shares. As a 
result of the merger, the number of authorized shares will be 255,000,000, of   
which 250,000,000 will be common shares and 5,000,000 will be preferred shares. 

    The Duke Charter authorizes the Duke Board, without shareholder approval, to
provide for the issuance of Duke preferred shares in one or more series and to  
fix the designations and the powers, preferences, conversion and other rights,  
voting rights, restrictions and limitations as to dividends, liquidation        
preference, qualifications and terms and conditions of redemption as the Duke   
Board may determine.                                                            

Weeks is authorized to issue 100,000,000 common shares and 20,000,000   
preferred shares.                                                               

   The Weeks Charter authorizes the Weeks Board, without shareholder approval,
to provide for the issuance of Weeks preferred shares in one or more series and 
to fix the designations and the powers, preferences, conversion and other       
rights, voting rights, restrictions and limitations as to dividends, liquidation
preference, qualifications and terms and conditions of redemption as the Weeks  
Board may determine.

VOTING                                                                          

  Each holder of Duke common shares is entitled to one vote per share and to
the same and identical voting rights as other holders of Duke common shares.    
Holders of Duke common shares do not have cumulative voting rights. Except as   
may otherwise be provided in the Duke Charter, a designation of a series of Duke
preferred shares or as otherwise expressly required by law, holders of Duke     
preferred shares do not have any voting rights.                                 

   Each holder of Weeks common shares is entitled to one vote per share and to
the same and identical voting rights as other holders of Weeks common shares.   
Holders of Weeks common shares do not have cumulative voting rights. Holders of 
Weeks preferred shares have such voting rights, if any, as established by the   
Weeks Board in the designation of a series of Weeks preferred shares or as      
otherwise expressly required by law.                                            

BOARD OF DIRECTORS                                                              

The Duke Charter and Duke Bylaws currently provide that the number of   
directors will be between five and 15. A proposed additional amendment to the   
Duke Charter, if approved, will increase the Board to no more than 23 directors.
The directors are divided into three classes and hold office for staggered three
year terms.                                                                     

The Weeks Bylaws currently provide that the number of directors will be 
eleven. The Weeks directors are divided into three classes and serve staggered  
three year terms pursuant to the Weeks Charter.                                 

REMOVAL OF DIRECTORS                                                            

Under the IBCL, directors may be removed in any manner provided in the  
articles of incorporation. In addition, directors may be removed by the         
shareholders and directors with or without cause unless the articles of         
incorporation specify otherwise. The Duke Charter provides that a director may  
be removed for cause by the affirmative vote of a majority of the shareholders  
at a meeting called expressly for such purpose.                                 

   The GBCC provides that if the directors have staggered terms, directors may
be removed only for cause, unless the articles of incorporation provide         
otherwise. The Weeks Charter has not modified this provision.                   

SPECIAL MEETINGS OF THE SHAREHOLDERS                                            

 The IBCL provides that a special meeting of shareholders may be called by
the Board of Directors or persons specifically authorized to do so by the       
articles of incorporation or bylaws and if no percentage of votes necessary to  
demand such a meeting is specified, the demand must be made by the holders of   
all of the votes entitled to be cast on the issue.                              

 Pursuant to the Duke Bylaws, a special meeting of the shareholders may be
called at any time by the chairman of the Board of Directors, a majority of the 
Board of Directors, a majority of unaffiliated directors, the president of Duke 
or at the request of the owners of 10% of the outstanding common shares entitled
to vote.                                                                        

Under the GBCC, a special meeting of shareholders may be called by the  
holders of 25% of shares entitled to vote, or such greater or lesser percentage 
as is provided in the articles of incorporation or bylaws.                      

 The Weeks Bylaws provide that special meetings of the shareholders may be
called by the Board of Directors or by the chairman of the Board, and upon the  
written request of more than 50% of the outstanding shares entitled to vote.

SHAREHOLDER ACTION BY WRITTEN CONSENT                                           

The IBCL permits shareholders to act without a meeting only by unanimous
written consent.                                                                

   The Duke Charter prohibits shareholder action by written consent in lieu of
a meeting.                                                                      

Under the GBCC, shareholders may act without a meeting if the action is 
taken by all the shareholders entitled to vote on the action or, if provided in 
the articles of incorporation, by the number of shares necessary to take the    
action at a meeting. The Weeks Charter has not modified the GBCC requirement    
that actions without a meeting be taken by all the shareholders.                

APPRAISAL RIGHTS IN MERGERS AND REORGANIZATIONS                                 

 The GBCC and the IBCL allow shareholders, under certain circumstances, to
dissent from certain corporate transactions and to receive fair value for their 
shares in lieu of the consideration they would otherwise receive in the         
transaction.                                                                    

Under the IBCL, there are no dissenters' rights for shareholders of a   
company which has shares registered on a national securities exchange or traded 
through the NASDAQ National Market System.                                      

Under the GBCC, there are no dissenters' rights for shareholders of a   
company which has shares registered on a national securities exchange or are    
held of record by more than 2,000 shareholders, unless pursuant to a plan of    
merger the holders of shares are required under the plan of merger to accept for
their shares anything except shares of the surviving corporation, which are     
registered on a national securities exchange as of the effective date of the    
merger or if the articles of incorporation or a resolution of the Board of      
Directors approving the transaction provides otherwise.                         

POWER TO ADOPT, AMEND OR REPEAL BY-LAWS                                         

    The IBCL and the GBCC reserve the power to amend or repeal by-laws solely to
the corporation's Board of Directors unless the articles of incorporation       
provide otherwise.                                                              

    The Duke Charter allows the shareholders or the directors to amend or repeal
any provision of the bylaws by a majority vote.                                 

    The Weeks Bylaws permit amendment by a majority of the Board, but any bylaws
adopted by the Board of Directors may be amended or new bylaws adopted, by a    
majority shareholder vote. The Weeks Bylaws also permit shareholders to         
prescribe that any bylaw adopted by them may not be amended or repealed by the  
Board of Directors.                                                             

AMENDMENT OF ARTICLES OF INCORPORATION                                          

    Under the IBCL, certain amendments to the Duke Charter are permitted without
shareholder action; however, shareholders are entitled to vote on a proposed    
amendment if the amendment would (1) increase or decrease the aggregate number  
of authorized shares of the class; (2) effect an exchange or reclassification of
all or part of the shares of the class into shares of another class; (3) effect 
an exchange or reclassification, or create the right of exchange, of all or part
of the shares of another class into shares of the class; (4) change the         
designation, rights, preferences, or limitations of all or part of the shares of
the class; (5) change the shares of all or part of the class into a different   
number of shares of the same class; (6) create a new class of shares having     
rights or preferences with respect to distributions or to dissolution that are  
prior, superior, or substantially equal to the shares of the class (except for  
any series created by the Duke Board as permitted by the Duke Charter); (7)     
increase the rights, preferences, or number of authorized shares of any class   
that, after giving effect to the amendment, have rights or preferences with     
respect to distributions or to dissolution that are prior, superior, or         
substantially equal to the shares of the class; (8) limit or deny an existing   
preemptive right of all or part of the shares of the class; or (9) cancel or

otherwise affect rights to distributions or dividends that have accumulated but 
not yet been declared on all or part of the shares of the class.                

 Article XI of Duke's Charter provides that either the shareholders or the
Board of Directors may amend or repeal certain provisions of the Duke Charter by
a majority vote and other specified provisions may only be amended or repealed  
by an 80% vote of the issued and outstanding shares of capital stock.           

   The GBCC provides for voting substantially similar to the voting provisions
enumerated in the IBCL, but also requires a shareholder vote if a proposed      
amendment would cancel, redeem or repurchase all or part of the shares of the   
class.                                                                          

   The affirmative vote of a majority of shareholders is required to amend the
Weeks Charter.                                                                  

ANTI-TAKEOVER STATUTES                                                          

    Chapter 43 of the IBCL generally prohibits a "resident domestic corporation"
of Indiana, such as Duke, from engaging in any "Business Combination" (as       
defined below) with any "Interested Shareholder" (defined generally as any      
person that, individually or with or through any of its affiliates or           
associates, beneficially owns 10% or more of the outstanding voting securities  
of a corporation) for a period of five years after the date the person becomes  
an Interested Shareholder unless, before such person became an Interested       
Shareholder, the Board of Directors of the corporation approved either the      
business combination or the purchase of more than 10% of the corporation's      
voting securities by the Interested Shareholder. Chapter 43 also provides that a
resident domestic corporation may not engage in a merger or other business      
combination with an Interested Shareholder at any time unless one of three      
conditions is satisfied: (1) the Board of Directors of the corporation had,     
before such person became an Interested Shareholder, approved either the        
business combination or the purchase of more than 10% of the corporation's      
voting securities by the Interested Shareholder; (2) certain "fair price"       
criteria are satisfied (including a requirement that the Interested Shareholder 
and its affiliates and associates have not purchased any additional shares after
first acquiring 10% of the corporation's voting securities); or (3) five years  
have passed since the Interested Shareholder acquired more than 10% of the      
corporation's voting securities and the Business Combination is approved by a   
majority of the "disinterested" voting securities of the corporation.           

A "Business Combination" is defined in Chapter 43 of the IBCL as (1) any
merger of a resident domestic corporation or any of its subsidiaries with (A) an
Interested Shareholder or (B) any other corporation which is, or after a merger 
or consolidation would be, an affiliate or associate of an Interested           
Shareholder; (2) any sale, lease, exchange, mortgage, pledge, transfer or other 
disposition (in one transaction or a series of transactions) to or with an      
Interested Shareholder or any of its affiliates or associates of assets of a    
resident domestic corporation or any of its subsidiaries (A) having an aggregate
market value equal to 10% or more of the aggregate market value of all assets,  
determined on a consolidated basis, of the resident domestic corporation, (B)   
having an aggregate market value equal to 10% or more of the aggregate market   
value of all the outstanding shares of the resident domestic corporation, or (C)
representing 10% or more of the earning power or net income, determined on a    
consolidated basis, of the resident domestic corporation; (3) the issuance or   
transfer by a resident domestic corporation or any of its subsidiaries (in one  
transaction or a series of transactions) of any shares of the resident domestic 
corporation or any of its subsidiaries which has an aggregate market value equal
to 5% or more of the aggregate market value of all the outstanding shares of the
resident domestic corporation to an Interested Shareholder or any of its        
affiliates or associates, except pursuant to the exercise of warrants or rights 
to purchase shares offered, or a dividend or distribution or made pro rata to

plan of liquidation or plan of dissolution of a resident domestic corporation   
proposed by, or pursuant to any agreement, arrangement or understanding with, an
Interested Shareholder or any of its affiliates or associates; (5) any

shares, or any reverse share split), or recapitalization of a resident domestic 
corporation, or any merger or consolidation of a domestic corporation with any  
of its subsidiaries, or any other transaction (whether or not with or into or   
otherwise involving an Interested Shareholder), proposed by, or pursuant to any 
agreement, arrangement or understanding with, an Interested Shareholder or any  
of its affiliates or associates, which has the effect, directly or indirectly,  
of increasing the proportionate share of the outstanding shares of any class or 
series of voting shares or securities convertible into voting shares of a       
resident domestic corporation or any of its subsidiaries which is directly or   
indirectly owned by the Interested Shareholder or any of its affiliates or      
associates (except as a result of immaterial changes due to fractional share    
adjustments); or (6) any receipt by an Interested Shareholder or any of its     
affiliates or associates, directly or indirectly (except proportionally as a    
shareholder of the resident domestic corporation), of any loans, advances,      
guarantees, pledges or other financial assistance or any tax credits or tax     
advantages provided by or through a resident domestic corporation.              

The GBCC restricts certain business combinations with "interested       
shareholders" (as defined below) (the "Business Combination Statute") and       
contains fair price requirements applicable to certain mergers with certain     
interested shareholders (the "Fair Price Statute"). In accordance with the      
provisions of these statutes, a company must elect in its articles or bylaws to 
be covered by the restrictions imposed by these statutes. Weeks has not elected 
to be covered by such restrictions; however, Weeks, by action of the Board of   
Directors without shareholder approval, may in the future amend the Weeks Bylaws
to make such an election. Furthermore, shareholders may amend or repeal the     
Weeks Bylaws or adopt new Weeks Bylaws (even though the Bylaws may also be      
amended or repealed by its Board of Directors) and may also expressly provide   
that any Bylaw so amended or repealed by them may not be amended or repealed by 
the Board of Directors.                                                         

The Business Combination Statute regulates business combinations such as
mergers, consolidations, share exchanges and asset purchases where the acquired 
business has at least 100 shareholders residing in Georgia and has its principal
office in Georgia, as Weeks does, and where the acquiror became an interested   
shareholder of the corporation, unless either (1) the transaction resulting in  
such acquiror becoming an interested shareholder or the business combination    
received the approval of the corporation's board of directors prior to the date 
on which the acquiror became an interested shareholder, or (2) the acquiror     
became the owner of at least 90% of the outstanding voting shares of the        
corporation (excluding shares held by directors, officers and affiliates of the 
corporation and shares held by certain other persons) in the same transaction in
which the acquiror became an interested shareholder. For purposes of the        
Business Combination Statute and the Fair Price Statute, an "interested         
shareholder" generally is any person who directly or indirectly, alone or in    
concert with others, beneficially owns or controls 10% or more of the voting    
power of the outstanding voting shares of the corporation. The Business         
Combination Statute prohibits business combinations with an unapproved          
interested shareholder for a period of five years after the date on which such  
person became an interested shareholder. The Business Combination Statute is    
broad in its scope and is designed to inhibit unfriendly acquisitions.          

The Fair Price Statute prohibits certain business combinations between a
Georgia corporation and an interested shareholder. The Fair Price Statute would 
permit the business combination to be effected if (1) certain "fair price"      
criteria are satisfied, (2) the business combination is unanimously approved by 
the continuing directors, (3) the business combination is recommended by at     
least two-thirds of the continuing directors and approved by a majority of the  
votes entitled to be cast by holders of voting shares, other than voting shares 
beneficially owned by the interested shareholder, or (4) the interested         
shareholder has been such for at least three years and has not increased his    
ownership position in such three-year period by more than one percent in any    
twelve month period. The Fair Price Statute is designed to inhibit unfriendly   
acquisitions that do not satisfy the specified "fair price" requirements.       

 The Duke Charter contains a business combination provision ("Article IX")
similar to the IBCL and the GBCC. However, Article IX defines a "business       
combination" differently than either the IBCL or the

GBCC and, as a result, may afford protection to Duke's shareholders in certain  
situations in which Chapter 43 would not apply.                                 

SHAREHOLDER RIGHTS AGREEMENTS                                                   

Each of Duke and Weeks has a rights agreement pursuant to which common  
shareholders are granted rights to purchase fractional interests in preferred   
shares of the companies upon the occurrence of certain triggering events. The   
Weeks shareholder rights plan and rights agreement will be terminated           
immediately prior to the effective time of the merger pursuant to the terms of  
the merger agreement. Each Weeks shareholder entitled to receive Duke common    
shares pursuant to the merger will also receive associated rights to purchase   
fractional interests in Duke preferred shares pursuant to the terms of the Duke 
rights agreement, dated as of July 23, 1998.                                    

    Under the Duke rights agreement, each common shareholder receives a dividend
of one right (a "Right") for each outstanding Duke common share which entitles  
the holder to purchase 1/1,000 of a Series C Junior Preferred Share (a "Unit")  
of Duke at a purchase price of $95.00 per Unit, subject to adjustment to prevent
dilution (the "Series C Purchase Price"). Generally, each Unit has substantially
the same voting rights as one Duke common share. The Rights expire on July 23,  
2008 unless redeemed earlier by Duke.                                           

Generally, the Rights become exercisable if:                            

- any person or group becomes the beneficial owner of 15% or more of the
      outstanding common shares of Duke (such person being an "Acquiring Person"
 and the date of the announcement being the "Stock Acquisition Date");

    - a majority of the directors serving on the Duke Board immediately prior to
   the Stock Acquisition Date or the directors appointed by such directors
   (the "Continuing Directors") declare that a 10% common shareholder is a
detriment to the interests of Duke (an "Adverse Person");           

  - a person or group commences a tender offer that would result in a person
  acquiring 15% of the then outstanding common shares, unless the tender
    offer is for all outstanding shares and deemed fair by a majority of the
Continuing Directors; or                                            

 - it is publicly announced that a person or affiliated group has acquired
40% or more of the then outstanding common shares of Duke.          

    Under certain circumstances, once the Rights are exercisable, each holder of
a Right, except any Acquiring Person or Adverse Person, may receive, upon       
exercise, Units having a value equal to two times the Series C Purchase Price.  
Additionally, upon the acquisition or sale of Duke, each holder of a Right may  
receive, upon exercise, common stock of the Acquiring Person or Adverse Person  
having a value equal to two times the exercise price of the Right.              

   At any time before the Rights are exercisable, a majority of the Continuing
Directors of Duke may redeem the Rights at a price of $.0025 per Right, or      
exchange the Rights for Duke common shares at an exchange ratio determined      
pursuant to the Rights Agreement.                                               

    The Rights may have certain anti-takeover effects and will cause substantial
dilution to a person or group that attempts to acquire Duke on terms not        
approved by a majority of the Continuing Directors, unless the offer is         
conditioned on a number of the Rights being acquired. However, the Rights should
not interfere with any merger approved by a majority of the Continuing Directors
because the Rights may be redeemed by Duke. Thus, the Rights are intended to    
encourage persons that seek to acquire control of Duke to initiate such an      
acquisition through negotiations with the Board of Directors. To the extent any 
potential acquirors are deterred by the Rights, the Rights may have the effect  
of preserving incumbent management in office.

INDIANA CONTROL SHARE ACQUISITION STATUTE                                       

 Indiana has a control share acquisition statute, which generally provides
that any person or group of persons that acquires the power to vote more than   
specified levels (one-fifth, one-third or a majority) of the shares of certain  
domestic corporations in transactions not approved by the corporation's Board of
Directors will not have the right to vote such shares unless granted voting     
rights by the holders of a majority of the votes entitled to be cast, excluding 
"Interested Shares." "Interested Shares" are those shares held by the acquiring 
person, officers of the corporation and employees of the corporation who are    
also directors of the corporation. If approval of voting power for the shares is
obtained at one of the specified levels, additional shareholder approvals are   
required when a shareholder seeks to acquire the power to vote shares at the    
next level. In the absence of such approval, the additional shares acquired by  
the shareholder may not be voted. The Indiana control share acquisition statute 
is applicable only to an Indiana corporation that has (1) 100 or more           
shareholders; (2) its principal place of business, its principal office, or     
substantial assets within Indiana; and (3) either (A) more than 10% of its      
shareholders as residents of Indiana, (B) more than 10% of its shares owned by  
Indiana residents, or (C) 10,000 shareholders resident in Indiana. Duke-Weeks   
immediately after the merger will meet these requirements and, consequently, the
control share acquisition statute will continue to provide additional deterrents
to acquisitions of control of Duke-Weeks.                                       

ADDITIONAL PROVISIONS OF THE IBCL                                               

The IBCL specifically authorizes directors, in considering the best     
interests of a corporation, to consider the effects of any action on            
shareholders, employees, suppliers, and customers of the corporation, on        
communities in which offices or other facilities of the corporation are located,
and any other factors the directors consider pertinent. Under the IBCL,         
directors are not required to approve a proposed business combination or other  
corporate action if the directors determine in good faith that such approval is 
not in the best interest of the corporation. In addition, the IBCL states that  
directors are not required to redeem any rights under or render inapplicable a  
shareholder rights plan or to take or decline to take any other action solely   
because of the effects such action might have on a proposed change of control of
the corporation or the amounts to be paid to shareholders upon such a change of 
control.                                                                        

    In taking or declining to take any action or in making any recommendation to
a corporation's shareholders with respect to any matter, directors are          
authorized under the IBCL to consider both the short-term and long-term         
interests of the corporation as well as interests of other constituencies and   
other relevant factors. Any determination made with respect to the foregoing by 
a majority of the disinterested directors is conclusively presumed to be valid  
unless it can be demonstrated that the determination was not made in good faith.

  These provisions of the IBCL may give the Board of Directors of Duke-Weeks
greater flexibility in responding to acquisition proposals, and accordingly, it 
may be more difficult for an acquiror to gain control of Duke-Weeks in a        
transaction not approved by the Board of Directors of Duke-Weeks.

THE PROPOSAL TO INCREASE THE SIZE OF DUKE'S BOARD 

 THE FOLLOWING DESCRIPTION, WHICH SUMMARIZES A PROPOSED CHANGE TO THE DUKE
ARTICLES OF INCORPORATION, WHICH WOULD INCREASE THE SIZE OF THE DUKE BOARD IS   
QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FORM OF THE DUKE ARTICLES OF      
INCORPORATION, AMENDED AND RESTATED TO SHOW THE CHANGES IF THE PROPOSAL IS      
APPROVED ATTACHED AS ANNEX D HERETO.                                            

The Board of Directors of Duke has unanimously approved the following   
additional amendment to Duke's Articles of Incorporation because they believe   
the amendment will enable shareholders to realize the full benefits contemplated
by the merger agreement and recommends that Duke's shareholders vote "FOR" the  
approval of the proposed amendment to the Duke Articles of Incorporation.       

    The amendment would expand the maximum number of directors on the Duke Board
from 15 directors to 23 directors. The purpose of this amendment is to expand   
the Board in order to include the members of the Weeks Board without having to  
require any members of the Duke Board to resign as directors.                   

  The proposed additional charter amendment requires the affirmative vote of
at least 80% of the issued and outstanding common shares and preferred shares of
Duke, voting together as a single class.                                        

    At the effective time of the merger, if this additional charter amendment is
approved, Duke's Bylaws will be amended to increase the size of Duke's Board to 
23. If the additional charter amendment is not approved, the size of Duke's     
Board will remain at 15.                                                        

Adoption of the additional charter amendment described above is not a   
condition to consummation of the merger.

THE PROPOSAL FOR ADDITIONAL AMENDMENTS TO DUKE'S ARTICLES 

   THE FOLLOWING DESCRIPTION, WHICH SUMMARIZES TWO ADDITIONAL PROPOSED CHANGES
TO THE DUKE ARTICLES OF INCORPORATION, IS QUALIFIED IN ITS ENTIRETY BY REFERENCE
TO THE FORM OF THE DUKE ARTICLES OF INCORPORATION, AMENDED AND RESTATED TO SHOW 
THE CHANGES IF THE PROPOSAL IS APPROVED ATTACHED AS ANNEX D HERETO.             

The Board of Directors of Duke has unanimously approved the following   
additional amendments to Duke's Articles of Incorporation and recommend that    
Duke's shareholders vote "FOR" the approval of the proposed amendments to the   
Duke Articles of Incorporation.                                                 

   - The first amendment would change the existing requirement that 80% of the
     outstanding shares of CAPITAL STOCK of Duke approve certain amendments to
  Duke's articles of incorporation to require the approval of 80% of the
  COMMON SHARES of Duke. The purpose of this amendment is to make Duke's
   Articles of Incorporation consistent with the terms of Duke's preferred
     shares which have no voting rights except as specified in the designating
      amendment creating a particular series of preferred shares. This amendment
      will also give Duke-Weeks more flexibility in setting the voting rights of
preferred shares on a series by series basis.                       

    - The second amendment would change the existing requirement that 80% of the
    outstanding shares of capital stock of Duke approve any amendment to the
provisions of the Articles of Incorporation relating to the number, 
  classes, term of office and qualifications of directors to require the
    approval of a majority of the common shares of Duke. The purpose of this
    amendment is to give Duke what it believes is more customary flexibility
to structure its Board of Directors and to ensure that the common   
      shareholders who have the right to elect directors without any approval of
the preferred shares, have the right to approve any changes to the  
structure of the Board without the approval of the preferred shares.

  The proposed additional charter amendments require the affirmative vote of
at least 80% of the issued and outstanding common shares and preferred shares of
Duke, voting together as a single class, and also the affirmative vote of at    
least two-thirds of the issued and outstanding shares of each series of         
preferred shares.                                                               

Adoption of the additional charter amendments is not a condition to     
consummation of the merger.

DESCRIPTION OF DUKE CAPITAL STOCK ISSUED BEFORE THE MERGER

 Duke is authorized to issue 150,000,000 common shares, par value $.01 per
share, and 5,000,000 preferred shares, par value $.01 per share. At April 27,   
1999, the following Duke shares were outstanding: 86,751,130 common shares,     
300,000 9.10% Series A Cumulative Redeemable Preferred Shares, 300,000 7.99%    
Series B Cumulative Step-Up Premium Rate(sm) Preferred Shares, 540,000 7.375%   
Series D Convertible Cumulative Redeemable Preferred Shares, and 400,000 8.25%  
Series E Cumulative Redeemable Preferred Shares.                                

DESCRIPTION OF COMMON SHARES                                                    

  The following description of Duke common shares sets forth certain general
terms and is a summary of all material provisions of Duke common shares. The    
statements below describing Duke common shares are in all respects subject to   
and qualified in their entirety by reference to the applicable provisions of the
Duke Charter and Duke Bylaws.                                                   

   GENERAL.  All common shares issued will be duly authorized, fully paid, and
non-assessable when issued. Duke shareholders will be entitled to receive       
dividends when, as and if declared by the Duke Board, out of funds legally      
available therefor. Payment and declaration of dividends on Duke common shares  
and purchases of common shares by Duke will be subject to certain restrictions  
if Duke fails to pay dividends on outstanding preferred shares. See             
"--Description of Preferred Shares." Duke intends to continue to pay quarterly  
dividends. Upon any liquidation, dissolution or winding up of Duke, holders of  
Duke common shares will be entitled to share equally and ratably in any assets  
available for distribution to them, after payment or provision for payment of   
the debts and other liabilities of Duke and the preferential amounts owing with 
respect to any outstanding preferred shares. Holders of Duke common shares have 
no preemptive rights, which means they have no right to acquire any additional  
shares of Duke common shares that may be issued by Duke at a subsequent date.   

 Each outstanding Duke common share entitles the holder to one vote on all
matters presented to Duke shareholders for a vote.                              

  Common shares currently outstanding are listed for trading on the New York
Stock Exchange (the "NYSE"). The additional common shares to be issued in the   
merger have been approved for listing on the NYSE, subject to official notice of
issuance.                                                                       

    Holders of common shares have no right to cumulative voting for the election
of directors. Consequently, at each annual meeting of shareholders, the holders 
of a plurality of the common shares are able to elect all of the successors of  
the class of directors whose term expires at that meeting. Directors may be     
removed only for cause and only with the affirmative vote of the holders of a   
majority of the common shares entitled to vote in the election of directors.    

   CERTAIN PROVISIONS AFFECTING CHANGE OF CONTROL.  Pursuant to the IBCL, Duke
cannot merge with or sell all or substantially all of the assets of Duke, except
pursuant to a resolution approved by shareholders holding a majority of the     
shares voting on the resolution. Duke's Articles of Incorporation also contain  
provisions which may discourage certain types of transactions involving an      
actual or threatened change of control of Duke, including: (1) a requirement    
that, in the case of certain mergers, sales of assets, liquidations or          
dissolutions, or reclassifications or recapitalizations involving persons owning
10% or more of the capital stock of Duke, such transactions be approved by a    
vote of the holders of 80% of the issued and outstanding shares of capital stock
of Duke (or 80% of the issued and outstanding common shares of Duke if certain  
additional charter amendments are approved at the Duke annual meeting) or       
three-fourths of the continuing directors, or provide for payment of a price to 
affected shareholders for their shares not less than as specified in the        
Articles of Incorporation; (2) a requirement that any amendment or alteration of
certain provisions of the Articles of Incorporation affecting change of control 
be approved by the holders of 80% of the issued and outstanding capital stock of
Duke (or 80% of the issued and outstanding

common shares of Duke if certain additional charter amendments are approved at  
the Duke annual meeting); and (3) a staggered Board of Directors and a          
limitation on removal of directors to removal for cause as described above.     

  The partnership agreement for Duke OP also contains provisions which could
discourage transactions involving an actual or threatened change of control of  
Duke, including (1) a requirement that holders of at least 90% of the           
outstanding units of limited partnership interest, including units held by Duke,
approve any voluntary sale, exchange or other disposition, including a merger or
consolidation (other than a disposition occurring upon a financing or           
refinancing of the Duke OP), of all or substantially all of the assets of Duke  
OP in a single transaction or a series of related transactions; (2) a           
restriction against any assignment or transfer by Duke of its interest in Duke  
OP; and (3) a requirement that holders of more than 90% of the units approve any
merger, consolidation or other combination of Duke with or into another entity, 
or sale of all or substantially all of Duke's assets, or any reclassification or
recapitalization or change of outstanding common shares (other than certain     
changes in par value, stock splits, stock dividends or combinations) unless     
after the transaction substantially all of the assets of the surviving entity   
are contributed to Duke OP in exchange for units. On these matters, Duke's units
will be voted at the discretion of the directors of Duke who are not officers or
employees of Duke and do not hold units.                                        

OWNERSHIP LIMITS.  For Duke to qualify as a REIT under the Code, no more
than 50% in value of its outstanding capital shares may be owned, directly or   
indirectly, by five or fewer individuals (as defined in the Code to include     
certain entities) during the last half of a taxable year or during a            
proportionate part of a shorter taxable year. The common shares must also be    
beneficially owned by 100 or more persons during at least 335 days of a taxable 
year or during a proportionate part of a shorter taxable year. Because Duke     
expects to continue to qualify as a REIT, the Articles of Incorporation of Duke 
contain restrictions on the acquisition of common shares intended to ensure     
compliance with these requirements.                                             

 The Articles of Incorporation contain a restriction which authorizes, but
does not require, the Board of Directors to refuse to give effect to a transfer 
of common shares which, in its opinion, might jeopardize the status of Duke as a
REIT. This provision also renders null and void any purported acquisition of    
shares which would result in the disqualification of Duke as a REIT. The        
provision also gives the Board of Directors the authority to take such actions  
as it deems advisable to enforce the provision. Such actions might include, but 
are not limited to, refusing to give effect to, or seeking to enjoin, a transfer
which might jeopardize Duke's status as a REIT. The provision also requires any 
shareholder to provide Duke such information regarding his direct and indirect  
ownership of common shares as Duke may reasonably require.                      

DESCRIPTION OF PREFERRED SHARES                                                 

GENERAL.  Subject to the limitations prescribed by the Duke Charter, the
Duke Board is authorized to fix the number of shares constituting each series of
preferred shares and the designations and powers, preferences and relative,     
participating, optional or other special rights and qualifications, limitations 
or restrictions thereof, including such provisions as may be desired concerning 
voting, redemption, dividends, dissolution or the distribution of assets,       
conversion or exchange, and such other subjects or matters as may be fixed by   
resolution of the Board of Directors. The following description of the preferred
shares sets forth certain general terms and provisions which apply to those     
series of preferred shares which the Duke Board has designated through the date 
of this joint proxy statement and prospectus. The statements below describing   
the preferred shares are in all respects subject to and qualified in their      
entirety by reference to the applicable provisions of the Duke Charter and Duke 
Bylaws and each amendment to the Duke Charter designating terms of a series of  
preferred shares. The preferred shares are fully paid and nonassessable by Duke 
and have no preemptive rights.

    RANK.  Each series of preferred shares will, with respect to dividend rights
and rights upon liquidation, dissolution or winding up of Duke, rank senior to  
all classes or series of common shares of Duke, and on a parity with all other  
series of preferred shares.                                                     

   DIVIDENDS.  Holders of the preferred shares of each series will be entitled
to receive, when, as and if declared by the Board of Directors of Duke, out of  
assets of Duke legally available for payment, cash dividends at such rates and  
on such dates as are set forth in the applicable designating amendment to the   
Duke Charter creating the series. Dividends on any series of the preferred      
shares may be cumulative or non-cumulative, as provided with regard to a        
particular series. Dividends, if cumulative, will be cumulative from and after  
the date set forth in the applicable designating amendment.                     

Holders of the preferred shares will be entitled to receive dividends in
preference to the holders of common shares. When dividends are not paid in full 
(or a sum sufficient for such full payment is not so set apart) upon preferred  
shares of any series and the shares of any other series of preferred shares     
ranking on a parity as to dividends with the preferred shares of such series,   
all dividends declared upon preferred shares of such series and any other series
of preferred shares ranking on a parity as to dividends with such preferred     
shares shall be declared pro rata.                                              

REDEMPTION.  If so provided with regard to a particular series, the     
preferred shares will be subject to mandatory redemption or redemption at the   
option of Duke, as a whole or in part, in each case upon the terms, at the times
and at the redemption prices set forth in the designating amendment to the Duke 
Charter creating the series. A particular series of preferred shares may provide
that the shares may be redeemed only with the proceeds of an equity offering by 
Duke.                                                                           

No shares of any series of preferred shares shall be redeemed unless all
outstanding preferred shares of such series are simultaneously redeemed, unless 
full cumulative dividends on all shares of any series of preferred shares shall 
have been or contemporaneously are declared and paid or declared and a sum      
sufficient for the payment thereof set apart for payment for all past dividend  
periods and the then current dividend period. However, the foregoing shall not  
prevent the purchase or acquisition of preferred shares of such series to       
preserve the REIT status of Duke or pursuant to a purchase or exchange offer    
made on the same terms to holders of all outstanding preferred shares of such   
series.                                                                         

  If fewer than all of the outstanding preferred shares of any series are to
be redeemed, the number of shares to be redeemed will be determined by Duke and 
such shares may be redeemed pro rata from the holders of record of such shares  
in proportion to the number of such shares held or for which redemption is      
requested by such holder (with adjustments to avoid redemption of fractional    
shares) or by lot in a manner determined by Duke.                               

LIQUIDATION PREFERENCE.  Upon any voluntary or involuntary liquidation, 
dissolution or winding up of the affairs of Duke, then, before any distribution 
or payment shall be made to the holders of any common shares or any other class 
or series of capital shares of Duke ranking junior to the preferred shares in   
the distribution of assets upon any liquidation, dissolution or winding up of   
Duke, the holders of each series of preferred shares shall be entitled to       
receive out of assets of Duke legally available for distribution to shareholders
liquidating distributions in the amount of the liquidation preference per share 
with regard to a particular series, plus an amount equal to all dividends       
accrued and unpaid thereon (which shall not include any accumulation in respect 
of unpaid dividends for prior dividend periods if such preferred shares does not
have a cumulative dividend).                                                    

    VOTING RIGHTS.  Holders of the preferred shares will have voting rights only
to the extent permitted in the Duke Charter, and as set forth below or as       
otherwise from time to time required by law or as indicated in the Duke Charter 
amendment designating the series.                                               

    Each outstanding series of preferred shares provides that whenever dividends
on any shares of that series shall be in arrears for six or more consecutive    
quarterly periods, the holders of those preferred

shares (voting separately as a class with all other series of preferred shares  
upon which like voting rights have been conferred and are exercisable) will be  
entitled to vote for the election of two additional directors of Duke at a      
special meeting called by the holders of record of at least ten percent (10%) of
any series of preferred shares so in arrears (unless such request is received   
less than 90 days before the date fixed for the next annual or special meeting  
of the stockholders) or at the next annual meeting of stockholders, and at each 
subsequent annual meeting until (1) if such series of preferred shares has a    
cumulative dividend, all dividends accumulated on such shares of preferred      
shares for the past dividend periods and the then current dividend period shall 
have been fully paid or declared and a sum sufficient for the payment thereof   
set aside for payment or (2) if such series of preferred shares does not have a 
cumulative dividend, four consecutive quarterly dividends shall have been fully 
paid or declared and a sum sufficient for the payment thereof set aside for     
payment. In such case, the entire Board of Directors of Duke will be increased  
by two directors.                                                               

    Unless provided otherwise for any series of preferred shares, so long as any
preferred shares remain outstanding, Duke will not, without the affirmative vote
or consent of the holders of at least two-thirds of the shares of each series of
preferred shares outstanding at the time, given in person or by proxy, either in
writing or at a meeting (each such series voting separately as a class), (1)    
authorize or create, or increase the authorized or issued amount of, any class  
or series of capital stock ranking prior to such series of preferred shares with
respect to payment of dividends or the distribution of assets upon liquidation, 
dissolution or winding up or reclassify any authorized capital stock of Duke    
into such shares, or create, authorize or issue any obligation or security      
convertible into or evidencing the right to purchase any such shares; or (2)    
amend, alter or repeal the provisions of the Duke Charter or the designating    
amendment for such series of preferred shares, whether by merger, consolidation 
or otherwise, so as to materially and adversely affect any right, preference,   
privilege or voting power of such series of preferred shares or the holders     
thereof.                                                                        

  The foregoing voting provisions will not apply if, at or prior to the time
when the act with respect to which such vote would otherwise be required shall  
be effected, all outstanding shares of such series of preferred shares shall    
have been redeemed or called for redemption and sufficient funds shall have been
deposited in trust to effect such redemption.                                   

   CONVERSION RIGHTS.  The terms and conditions, if any, upon which any series
of preferred shares is convertible into common shares will be set forth in the  
Duke Charter amendment designating the series. Only the holders of the 7.375%   
Series D Convertible Cumulative Redeemable Preferred Shares had the right to    
convert to common shares.                                                       

DESCRIPTION OF DEPOSITARY SHARES                                                

  Duke may issue depositary receipts for depositary shares (also referred to
as "preference shares" when they relate to the 8.0% Series F Cumulative         
Redeemable Preferred Shares and the 8.625% Series H Cumulative Redeemable       
Preferred Shares to be issued to Weeks preferred shareholders in the merger),   
each of which will represent a fractional interest of a share of a particular   
series of preferred shares. Preferred shares of each series represented by      
depositary shares will be deposited under a separate deposit agreement among    
Duke, the depositary named therein and the holders from time to time of the     
depositary receipts. Subject to the terms of the applicable deposit agreement,  
each owner of a depositary receipt will be entitled, in proportion to the       
fractional interest of a share of a particular series of preferred shares       
represented by the depositary shares evidenced by such depositary receipt, to   
all the rights and preferences of the preferred shares represented by such      
depositary shares (including dividend, voting, conversion, redemption and       
liquidation rights).

DESCRIPTION OF DUKE CAPITAL STOCK ISSUED IN CONNECTION
WITH THE PROPOSED MERGER

   In connection with the proposed merger, Duke will issue to holders of Weeks
Series A Cumulative Redeemable Preferred Shares one preference share            
representing 1/1,000 of an 8.0% Series F Cumulative Redeemable Preferred Share  
of Duke for each outstanding Series A Cumulative Redeemable Preferred Share of  
Weeks. Duke will issue to holders of Weeks Series Cumulative Redeemable D       
Preferred Shares (if any) one preference share representing 1/1,000 of an 8.625%
Series H Cumulative Redeemable Preferred Share of Duke for each outstanding     
Series D Cumulative Redeemable Preferred Share of Weeks.                        

8.0% SERIES F CUMULATIVE REDEEMABLE PREFERRED SHARES                            

  Prior to the completion of the merger, Duke will adopt an amendment to its
Articles of Incorporation specifying a series of preferred shares consisting of 
up to 7,400 shares, designated 8.0% Series F Cumulative Redeemable Preferred    
Shares (the "Series F Preferred Shares"). Preference shares representing        
interests in 6,000 Series F Preferred Shares will be issued in the merger.      
Preference shares representing interests in up to an additional 1,400 Series F  
Preferred Shares are issuable upon conversion of the Series G Preferred Units or
the exercise of a warrant held by the holders of the Series G Preferred Units.  
The following summary of the material terms and provisions of the Series F      
Preferred Shares is qualified in its entirety by reference to the pertinent     
sections of the amendment designating the Series F Preferred Shares, which may  
be obtained from Duke.                                                          

   The transfer agent, registrar and dividends disbursing agent for the Series
F Preferred Shares will be American Stock Transfer & Trust Company.             

    Each preference share represents a 1/1,000 fractional interest in a Series F
Preferred Share. The Series F Preferred Shares will be deposited with American  
Stock Transfer & Trust Company, as depositary, under a deposit agreement which  
Duke will enter into with the depositary. The depositary will issue preference  
receipts which will evidence the preference shares. Subject to the terms of the 
deposit agreement, each holder of a preference receipt evidencing a preference  
share will be entitled to all the rights and preferences of a 1/1,000 fractional
interest in a Series F Preferred Share (including distribution, voting,         
redemption and liquidation rights and preferences).                             

    The preference shares have been approved for listing on the NYSE, subject to
official notice of issuance. The Series F Preferred Shares will not be listed,  
and we do not expect that there will be any trading market for the Series F     
Preferred Shares except as represented by preference shares.                    

 RANKING.  The Series F Preferred Shares will rank senior to Duke's common
shares with respect to payment of distributions or amounts upon the liquidation,
dissolution or winding up of Duke.                                              

    While any Series F Preferred Shares are outstanding, Duke may not authorize,
create or increase the authorized amount of any class of security that ranks    
senior to the Series F Preferred Shares with respect to the payment of dividends
or amounts payable upon liquidation, dissolution or winding up, or any class of 
security convertible into shares of such a class, without the consent of the    
holders of two-thirds of the outstanding Series F Preferred Shares and Parity   
Shares (as defined below), voting as a single class. However, Duke may create   
additional classes of other stock, increase the authorized number of preferred  
shares or issue series of preferred shares ranking on a parity with the Series F
Preferred Shares with respect, in each case, to the payment of dividends and    
amounts upon liquidation, dissolution and winding up ("Parity Shares") without  
the consent of any holder of Series F Preferred Shares. See "--Voting Rights"   
below.                                                                          

DIVIDENDS.  Holders of the Series F Preferred Shares are entitled to    
receive, when and as declared by the Board of Directors, out of funds legally   
available for the payment of dividends, cumulative dividends at the rate of 8.0%
of the liquidation preference per annum (equivalent to $2.00 per preference     
share per

annum). Dividends are cumulative from the date of original issue and are payable
quarterly in arrears on the last calendar day (or, if such day is not a business
day, the next business day) of each January, April, July and October (each, a   
"Quarterly Dividend Date"). Any dividends payable on the Series F Preferred     
Shares for any partial dividend period will be computed on a basis of the actual
number of days in such period. Dividends are payable to holders of record as    
they appear in the records of Duke at the close of business on the applicable   
record date, which is the 15(th) day of the calendar month in which the         
Quarterly Dividend Date falls or such other date designated as such by the Board
of Directors of Duke that is not more than 50 nor less than 10 days prior to    
such Quarterly Divided Date (each, a "Record Date"). Accrued and unpaid         
dividends for any past dividend periods may be declared and paid at any time and
for such interim periods to holders of record on the applicable Record Date. Any
dividend payment made on the Series F Preferred Shares is credited against the  
earliest accrued but unpaid dividend due with respect to the Series F Preferred 
shares that remains payable.                                                    

No dividends may be authorized by the Board of Directors or paid or set 
aside for payment if any agreement of Duke prohibits such authorization, payment
or setting apart for payment or provides that such authorization, payment or    
setting aside would constitute a breach thereof or a default thereunder, or if  
such authorization or payment is restricted or prohibited by law. Dividends on  
Series F Preferred Shares accrue whether or not Duke has earnings, whether or   
not there are funds legally available for the payment of such dividends and     
whether or not such dividends are declared. No interest, or sum of money in lieu
of interest, is payable in respect of any dividend payment or payments on the   
Series F Preferred shares that is in arrears. Holders of Series F Preferred     
Shares are not entitled to any dividends, whether payable in cash, property or  
shares of stock, in excess of the full cumulative dividends, as described       
herein, on the Series F Preferred Shares.                                       

If, for any taxable year, Duke elects to designate as "capital gain     
dividends" (as defined in Section 857 of the Code) any portion (the "Capital    
Gains Amount") of the dividends (within the meaning of the Code) paid or made   
available for the year to holders of all classes of capital stock, then the     
portion of the Capital Gains Amount that will be allocable to holders of Series 
F Preferred Shares will be in the same proportion that the dividends paid or    
made available to the holders of Series F Preferred Shares for the year bears to
the dividends.                                                                  

Except as provided in the next sentence, no dividends may be declared or
paid on any Parity Shares unless full cumulative dividends have been declared   
and paid or are contemporaneously declared and funds sufficient for the payment 
thereof set aside for such payment on the Series F Preferred shares for all     
prior dividend periods. If accrued dividends on the Series F Preferred Shares   
for all prior dividend periods have not been paid in full, then any dividend    
declared on the Series F Preferred Shares and on any Parity Shares for any      
dividend period will be declared ratably in proportion to accrued and unpaid    
dividends on the Series F Preferred shares and such Parity Shares.              

Duke may not (1) declare, pay or set apart funds for the payment of any 
dividend or other distribution with respect to any Junior Shares (as defined    
below) or (2) redeem, purchase or otherwise acquire for consideration any Junior
Shares through a sinking fund or otherwise (other than a redemption or purchase 
or other acquisition of common shares made for purposes of any employee         
incentive or benefit plan of Duke or any subsidiary), unless (A) all cumulative 
dividends with respect to the Series F Preferred Shares and any Parity Shares at
the time such dividends are payable have been paid or declared and funds have   
been set apart for payment of such dividends and (B) sufficient funds have been 
paid or declared and set apart for the payment of the dividend for the current  
dividend period with respect to the Series F Preferred Shares and any Parity    
Shares.                                                                         

   As used herein, (1) the term "dividend" does not include dividends or other
distributions payable solely in Fully Junior Shares (as defined below), or in   
options, warrants or rights to subscribe for or purchase any Fully Junior       
Shares, (2) the term "Junior Shares" means the common shares and any other class
or series of shares of capital stock of Duke now or hereafter issued and        
outstanding that rank junior

to the Series F Preferred Shares as to the payment of dividends or in the       
distributions of assets or amounts upon liquidation, dissolution and winding up 
and (3) the term "Fully Junior Shares" means Junior Shares (including the common
shares) that rank junior to the Series F Preferred Shares both as to the payment
of dividends and distribution of assets upon liquidation, dissolution and       
winding up.                                                                     

LIQUIDATION RIGHTS.  Upon any voluntary or involuntary liquidation,     
dissolution or winding up of Duke, the holders of Series F Preferred Shares will
be entitled to receive out of assets of Duke legally available for distribution 
to shareholders a liquidation preference of $25,000 per share (equivalent to    
$25.00 per preference share), plus an amount per Series F Preferred Share equal 
to all dividends (whether or not earned or declared) accrued and unpaid thereon 
to the date of final distribution to such holders, and no more.                 

  Until the holders of Series F Preferred Shares and Parity Shares have been
paid their liquidation preference in full, no payment will be made to any holder
of Junior Shares upon the liquidation, dissolution or winding up of Duke. If    
upon any liquidation, dissolution or winding up of Duke, the assets of Duke, or 
proceeds thereof, distributable among the holders of the Series F Preferred     
Shares are insufficient to pay in full the amount payable upon liquidation with 
respect to the Series F Preferred Shares and any other Parity Shares, then such 
assets, or the proceeds thereof, will be distributed among the holders of Series
F Preferred Shares and any such Parity Shares ratably in accordance with the    
respective amounts which would be payable on such Series F Preferred Shares and 
any other Parity Shares if all amounts payable thereon were paid in full Neither
a consolidation nor a merger of Duke with another entity, a statutory share     
exchange by Duke or a sale, lease or transfer of all or substantially all of    
Duke's assets will be considered a liquidation, dissolution or winding up,      
voluntary or involuntary, of Duke.                                              

   REDEMPTION.  The Series F Preferred Shares are not redeemable by Duke prior
to October 10, 2002. On and after October 10, 2002, Duke, at its option, upon   
publication in a newspaper of general circulation in New York, New York at least
once a week for two successive weeks and written notice to the holders of Series
F Preferred Shares, may redeem the Series F Preferred Shares, in whole or in    
part, at any time or from time to time, for cash at a redemption price of       
$25,000 per share (equivalent to $25.00 per preference share), plus accumulated,
accrued and unpaid dividends thereon to the date fixed for redemption, without  
interest. The redemption price of the Series F Preferred Shares (other than the 
portion thereof consisting of accrued and unpaid dividends) is payable solely   
out of proceeds from the sale of other capital stock of Duke, which may include 
common shares, preferred shares, preference shares, depositary shares,          
interests, participations or other ownership interests in Duke however          
designated (other than debt securities convertible into or exchangeable for     
equity securities), and any rights, warrants or options to purchase any thereof.
If fewer than all of the outstanding Series F Preferred Shares are to be        
redeemed, the number of shares to be redeemed will be determined by Duke and    
such shares may be redeemed pro rata from the holders of record of such shares  
in proportion to the number of such shares held by such holders (with           
adjustments to avoid redemption of fractional shares), by lot or by any other   
method determined by Duke in its sole discretion to be equitable.               

 Unless full cumulative dividends on all Series F Preferred Shares and any
Parity Shares have been or contemporaneously are declared and paid or declared  
and a sum sufficient for the payment thereof set apart for payment for all past 
dividend periods and the then-current dividend period, no Series F Preferred    
Shares or Parity Shares may be redeemed or purchased by Duke except pursuant to 
a purchase or exchange offer made on the same terms to holders of all           
outstanding Series F Preferred Shares or Parity Shares, as the case may be.     

 Notice of redemption will be mailed at least 30 days but not more than 90
days before the redemption date by the registrar to each holder of record of    
Series F Preferred Shares to be redeemed at the address shown on the stock      
transfer books of Duke. Each notice shall state: (1) the redemption date; (2)   
the number of Series F Preferred Shares to be redeemed; (3) the redemption price
per share; (4) the place or places where certificates for Series F Preferred    
Shares are to be surrendered for payment of the

redemption price; and (5) that dividends on the Series F Preferred Shares will  
cease to accrue on such redemption date. If fewer than all Series F Preferred   
Shares are to be redeemed, the notice mailed to each such holder thereof shall  
also specify the number of Series F Preferred Shares to be redeemed for such    
holder. If notice of redemption of any Series F Preferred Shares has been given 
and if the funds necessary for such redemption have been set aside by Duke in   
trust for the benefit of the holders of Series F Preferred Shares so called for 
redemption, then from and after the redemption date, dividends will cease to    
accrue on the Series F Preferred Shares, such Series F Preferred Shares shall no
longer be deemed outstanding and all rights of the holders of such shares will  
terminate, except the right to receive the redemption price.                    

The holders of Series F Preferred Shares at the close of business on a  
Record Date are entitled to receive the dividends payable with respect to such  
Series F Preferred Shares on the corresponding Quarterly Dividend Date          
notwithstanding the redemption thereof between such Record Date and the         
corresponding Quarterly Dividend Date or Duke's default in the payment of the   
dividend due. Duke will make no payment or allowance for unpaid dividends,      
whether or not in arrears, on Series F Preferred Shares which have been called  
for redemption, except as otherwise provided in the preceding sentence or to the
extent that such unpaid dividends are included in the redemption price.         

   The Series F Preferred Shares may not be redeemed except from proceeds from
the sale of other capital stock of Duke. The Series F Preferred Shares have no  
stated maturity and are not subject to any sinking fund or mandatory redemption.

   VOTING RIGHTS.  Except as indicated below, or except as otherwise from time
to time required by applicable law, the holders of Series F Preferred Shares    
have no voting rights.                                                          

If six consecutive quarterly dividends payable on the Series F Preferred
shares or any Parity Shares are in arrears, whether or not declared, the number 
of directors then constituting the Board of Directors of Duke will be increased 
by two, and the holders of Series F Preferred Shares, voting together as a class
with the holders of any other series of Parity Shares, will have the right to   
elect two additional directors to serve on Duke's Board of Directors at any     
annual meeting of shareholders or a properly called special meeting of the      
holders of the voting Parity Shares until all such dividends and dividends for  
the current quarterly period on the Series F Preferred shares and such other    
voting Parity Shares have been declared and paid or set aside for payment. Such 
voting rights will terminate when all such accrued and unpaid dividends have    
been declared and paid or set aside for payment. The term of office of all      
directors so elected will terminate with the termination of such voting rights. 

   The approval of two-thirds of the outstanding Series F Preferred Shares and
all other Parity Shares, voting as a single class, is required in order to (1)  
amend the Articles of Incorporation to affect materially and adversely the      
rights, preferences or voting power of the holders of the Series F Preferred    
Shares or the Parity Shares (except that if such amendment would materially and 
adversely affect any right, preference, privilege or voting power of the Series 
F Preferred Shares or another series of Parity Shares that is not enjoyed by the
other, then the approval of two-thirds of the holders of all series similarly   
affected shall be required); (2) enter into a share exchange that affects the   
Series F Preferred Shares, or consolidate Duke with or merge Duke with another  
entity, unless in each such case each Series F Preferred Share remains          
outstanding without a material adverse change to its terms and rights or is     
converted into or exchanged for preferred shares of the surviving entity having 
preferences, conversion and other rights, voting powers, restrictions,          
limitations as to dividends, qualifications and terms and conditions of         
redemption thereof identical to that of the Series F Preferred Shares (except   
for changes that do not materially and adversely affect the holders of Series F 
Preferred Shares); or (3) authorize, reclassify, create or increase the         
authorized or issued amount of any shares of any class, or any security         
convertible into shares of any class, having rights senior to the Series F      
Preferred Shares with respect to the payment of dividends or the distribution of
assets or amounts upon liquidation, dissolution or winding up of Duke.

  Except as provided above and as required by applicable law, the holders of
Series F Preferred Shares are not entitled to vote on any merger or             
consolidation involving Duke, on any share exchange or on a sale of all or      
substantially all of the assets of Duke.                                        

8.625% SERIES H CUMULATIVE REDEEMABLE PREFERRED SHARES                          

  Prior to the completion of the merger, Duke will adopt an amendment to its
Charter specifying a series of preferred shares (the "Series H Preferred        
Shares") consisting of up to 2,600 shares, designated 8.625% Series H Cumulative
Redeemable Preferred Shares. The following summary of the material terms and    
provisions of the Series H Preferred Shares is qualified in its entirety by     
reference to the pertinent sections of the amendment designating the Series H   
Preferred Shares, which may be obtained from Duke.                              

   The transfer agent, registrar and dividends disbursing agent for the Series
H Preferred Shares will be American Stock Transfer & Trust Company.             

    Each preference share represents a 1/1,000 fractional interest in a Series H
Preferred Share. The Series H Preferred Shares will be deposited with American  
Stock Transfer & Trust Company, as depositary, under a deposit agreement which  
Duke will enter into with the depositary. The depositary, will issue preference 
receipts which will evidence the preference shares. Subject to the terms of the 
deposit agreement, each holder of a preference receipt evidencing a preference  
share will be entitled to all the rights and preferences of a 1/1,000 fractional
interest in a Series H Preferred Share (including distribution, voting,         
redemption and liquidation rights and preferences).                             

 RANKING.  The Series H Preferred Shares will rank senior to Duke's common
shares with respect to payment of distributions or amounts upon our liquidation,
dissolution or winding up.                                                      

    While any Series H Preferred Shares are outstanding, Duke may not authorize,
create or increase the authorized amount of any class of security that ranks    
senior to the Series H Preferred Shares with respect to the payment of dividends
or amounts payable upon liquidation, dissolution or winding up, or any class of 
security convertible into shares of such a class, without the consent of the    
holders of two-thirds of the outstanding Series H Preferred Shares and Parity   
Shares (as defined below), voting as a single class. However, Duke may create   
additional classes of other stock, increase the authorized number of preferred  
shares or issue series of preferred shares ranking on a parity with the Series H
Preferred Shares with respect, in each case, to the payment of dividends and    
amounts upon liquidation, dissolution and winding up ("Parity Shares") without  
the consent of any holder of Series H Preferred Shares. See "--Voting Rights"   
below.                                                                          

DIVIDENDS.  Holders of the Series H Preferred Shares are entitled to    
receive, when and as declared by the Board of Directors, out of funds legally   
available for the payment of dividends, cumulative dividends at the rate of     
8.625% of the liquidation preference per annum (equivalent to $2.15625 per      
preference share) and are payable quarterly in arrears on the last calendar day 
(or, if such day is not a business day, the next business day) of each January, 
April, July and October (each, a "Quarterly Dividend Date"). Any dividends      
payable on the Series H Preferred Shares for any partial dividend period will be
computed on a basis of the actual number of days in such period. Dividends are  
payable to holders of record as they appear in the records of Duke at the close 
of business on the applicable record date, which is the 15(th) day of the       
calendar month in which the Quarterly Dividend Date falls or such other date    
designated as such by the Board of Directors of Duke that is not more than 50   
nor less than 10 days prior to such Quarterly Dividend Date (each, a "Record    
Date"). Accrued and unpaid dividends for any past dividend periods may be       
declared and paid at any time and for such interim periods to holders of record 
on the applicable Record Date. Any dividend payment made on the Series H        
Preferred Shares is credited against the earliest accrued but unpaid dividend   
due with respect to the Series H Preferred Shares that remains payable.         

No dividends may be authorized by the Board of Directors or paid or set 
aside for payment if any agreement of Duke prohibits such authorization, payment
or setting apart for payment or provides that

such authorization, payment or setting aside would constitute a breach thereof  
or a default thereunder, or if such authorization or payment is restricted or   
prohibited by law. Dividends on Series H Preferred Shares accrue whether or not 
Duke has earnings, whether or not there are funds legally available for the     
payment of such dividends and whether or not such dividends are declared. No    
interest, or sum of money in lieu of interest, is payable in respect of any     
dividend payment or payments on the Series H Preferred Shares that is in        
arrears. Holders of Series H Preferred Shares are not entitled to any dividends,
whether payable in cash, property or shares of stock, in excess of the full     
cumulative dividends, as described herein, on the Series H Preferred Shares.    

If, for any taxable year, Duke elects to designate as "capital gain     
dividends" (as defined in Section 857 of the Code) any portion (the "Capital    
Gains Amount") of the dividends (within the meaning of the Code) paid or made   
available for the year to holders of all classes of capital stock, then the     
portion of the Capital Gains Amount that will be allocable to holders of Series 
H Preferred Shares will be in the same portion that the dividends paid or made  
available to the holders of Series H Preferred Shares for the year bears to the 
dividends.                                                                      

Except as provided in the next sentence, no dividends may be declared or
paid on any Parity Shares unless full cumulative dividends have been declared   
and paid or are contemporaneously declared and funds sufficient for the payment 
thereof set aside for such payment on the Series H Preferred Shares for all     
prior dividend periods. If accrued dividends on the Series H Preferred Shares   
for all prior dividends periods have not been paid in full, then any dividend   
declared on the Series H Preferred Shares and on any Parity Shares for any      
dividend period will be declared ratably in proportion to accrued and unpaid    
dividends on the Series H Preferred Shares and such Parity Shares.              

Duke may not (1) declare, pay or set apart funds for the payment of any 
dividend or other distribution with respect to any Junior Shares (as defined    
below) or (2) redeem, purchase or otherwise acquire for consideration any Junior
Shares through a sinking fund or otherwise (other than a redemption or purchase 
or other acquisition of common shares made for purposes of any employee         
incentive or benefit plan of Duke or any subsidiary), unless (A) all cumulative 
dividends with respect to the Series H Preferred Shares and any Parity Shares at
the time such dividends are payable have been paid or declared and funds have   
been set apart for payment of such dividends and (B) the dividend for the       
current dividend period with respect to the Series H Preferred Shares and any   
Parity Shares.                                                                  

   As used herein, (1) the term "dividend" does not include dividends or other
distributions payable solely in Fully Junior Shares (as defined below), or in   
options, warrants or rights to subscribe for or purchase any Fully Junior       
Shares, (2) the term "Junior Shares" means the common shares and any other class
or series of shares of capital stock of Duke now or hereafter issued and        
outstanding that ranks junior to the Series H Preferred Shares as to the payment
of dividends or in the distributions of assets or amounts upon liquidation,     
dissolution and winding up, and (3) the term "Fully Junior Shares" means Junior 
Shares (including the common shares) that rank junior to the Series H Preferred 
Shares both as to the payment of dividends and distribution of assets upon      
liquidation, dissolution and winding up.                                        

LIQUIDATION RIGHTS.  Upon any voluntary or involuntary liquidation,     
dissolution or winding up of Duke, the holders of Series H Preferred Shares will
be entitled to receive out of assets of Duke legally available for distribution 
to shareholders a liquidation preference of $25,000 per share (equivalent to    
$25.00 per preference share), plus an amount per Series H Preferred Shares equal
to all dividends (whether or not earned or declared) accrued and unpaid thereon 
to the date of final distribution to such holders, and no more.                 

  Until the holders of Series H Preferred Shares and Parity Shares have been
paid their liquidation preference in full, no payment will be made to any holder
of Junior Shares upon the liquidation, dissolution or winding up of Duke. If    
upon any liquidation, dissolution or winding up of Duke, the assets of Duke, or 
proceeds thereof, distributable among the holders of the Series H Preferred     
Shares are insufficient to pay in full the amount payable upon liquidation with 
respect to the Series H Preferred

Shares and any other Parity Shares, then such assets, or the proceeds thereof,  
will be distributed among the holders of Series H Preferred Shares and any such 
Parity Shares ratably in accordance with the respective amounts which would be  
payable on such Series H Preferred Shares and any other Parity Shares if all    
amounts payable thereon were paid in full. Neither a consolidation nor a merger 
of Duke with another entity, a statutory share exchange by Duke or a sale, lease
or transfer of all or substantially all of Duke's assets will be considered a   
liquidation, dissolution or winding up, voluntary or involuntary, of Duke.      

   REDEMPTION.  The Series H Preferred Shares are not redeemable by Duke prior
to November 12, 2003. On and after November 12, 2003, Duke, at its option, upon 
publication in a newspaper of general circulation in New York, New York at least
once a week for two successive weeks and written notice to the holders of Series
H Preferred Shares, may redeem the Series H Preferred Shares, in whole or in    
part, at any time or from time to time, for cash at a redemption price of       
$25,000 per share (equivalent to $25.00 per preference share), plus accumulated,
accrued and unpaid dividends thereon to the date fixed for redemption, without  
interest. The redemption price of the Series H Preferred Shares (other than the 
portion thereof consisting of accrued and unpaid dividends) is payable solely   
out of proceeds from the sale of other capital stock of Duke, which may include 
common shares, preferred shares, preference shares, depository shares,          
interests, participations or other ownership interests in Duke however          
designated (other than debt securities convertible into or exchangeable for     
equity securities), and any rights, warrants or options to purchase any thereof.
If fewer than all of the outstanding Series H Preferred Shares are to be        
redeemed, the number of shares to be redeemed will be determined by Duke and    
such shares may be redeemed pro rata from the holders of record of such shares  
in proportion to the number of such shares held by such holders (with           
adjustments to avoid redemption of fractional shares), by lot or by any other   
method determined by Duke in its sole discretion to be equitable.               

 Unless full cumulative dividends on all Series H Preferred Shares and any
Parity Shares have been or contemporaneously are declared and paid or declared  
and a sum sufficient for the payment thereof set apart for payment for all past 
dividend periods and the then-current dividend period, no Series H Preferred    
Shares or Parity Shares may be redeemed or purchased by Duke except pursuant to 
a purchase or exchange offer made on the same terms to holders of all           
outstanding Series H Preferred Shares or Parity Shares may be redeemed or       
purchased by Duke except pursuant to a purchase or exchange offer made on the   
same terms to holders of all outstanding Series H Preferred Shares or Parity    
Shares, as the case may be.                                                     

 Notice of redemption will be mailed at least 30 days but not more than 90
days before the redemption date by the registrar to each holder of record of    
Series H Preferred Shares to be redeemed at the address shown on the stock      
transfer books of Duke. Each notice shall state: (1) the redemption date; (2)   
the number of Series H Preferred Shares to be redeemed; (3) the redemption price
per share; (4) the place or places where certificates for Series H Preferred    
Shares are to be surrendered for payment of the redemption price; and (5) that  
dividends on the Series H Preferred Shares will cease to accrue on such         
redemption date. If fewer than all Series H Preferred Shares are to be redeemed,
the notice mailed to each such holder thereof shall also specify the number of  
Series H Preferred Shares to be redeemed from such holder. If notice of         
redemption of any Series H Preferred Shares has been given and if the funds     
necessary for such redemption have been set aside by Duke in trust for the      
benefit of the holders of Series H Preferred Shares so called for redemption,   
then from and after the redemption date, dividends will cease to accrue on the  
Series H Preferred shares, such Series H Preferred Shares shall no longer be    
deemed outstanding and all rights of the holders of such shares will terminate, 
except the right to receive the redemption price.                               

The holders of Series H Preferred Shares at the close of business on a  
Record Date are entitled to receive the dividends payable with respect to such  
Series H Preferred Shares on the corresponding Quarterly Dividend Date          
notwithstanding the redemption thereof between such Record Date and the         
corresponding quarterly Dividend Date or Duke's default in the payment of the   
dividend due. Duke will make no payment or allowance for unpaid dividends,      
whether or not in arrears, on Series H Preferred

Shares which have been called for redemption, except as otherwise provided in   
the preceding sentence or to the extent that such unpaid dividends are included 
in the redemption price.                                                        

   The Series H Preferred Shares may not be redeemed except from proceeds from
the sale of other capital stock of Duke. The Series H Preferred Shares have no  
stated maturity and are not subject to any sinking fund or mandatory redemption.

   VOTING RIGHTS.  Except as indicated below, or except as otherwise from time
to time required by applicable law, the holders of Series H Preferred Shares    
have no voting rights.                                                          

If six consecutive quarterly dividends payable on the Series H Preferred
Shares or any Parity Shares are in arrears, whether or not declared, the number 
of directors then constituting the Board of Directors of Duke will be increased 
by two, and the holders of Series H Preferred Shares, voting together as a class
with the holders of any other series of Parity Shares, will have the right to   
elect two additional directors to serve on Duke's Board of Directors at any     
annual meeting of shareholders or a properly called special meeting of the      
holders of the voting Parity Shares until all such dividends and dividends for  
the current quarterly period on the Series H Preferred Shares and such other    
voting Parity Shares have been declared and paid or set aside for payment. Such 
voting rights will terminate when all such accrued and unpaid dividends have    
been declared and paid or set aside for payment. The term of office of all      
directors so elected will terminate with the termination of such voting rights. 

   The approval of two-thirds of the outstanding Series H Preferred Shares and
all other Parity Shares, voting as a single class, is required to order to (1)  
amend the Articles to affect materially and adversely the rights, preferences or
voting power of the holders of the Series H Preferred Shares or the Parity      
Shares (except that if such amendment would materially and adversely affect any 
right, preference, privilege or voting power of the Series H Preferred Shares or
another series of Parity Shares that is not enjoyed by the other, then the      
approval of two-thirds of the holders of all series similarly affected shall be 
required); (2) enter into a share exchange that affects the Series H Preferred  
Shares, or consolidate Duke with or merge Duke with another entity, unless in   
each such case each Series H Preferred Share remains outstanding without a      
material adverse change to its terms and rights or is converted into or         
exchanged for preferred shares of the surviving entity having preferences,      
conversion and other rights, voting powers, restrictions, limitations as to     
dividends, qualifications and terms and conditions of redemption thereof        
identical to that of the Series H Preferred Shares (except for changes that do  
not materially and adversely affect the holders of Series H Preferred Shares);  
or (3) authorize, reclassify, create or increase the authorized or issued amount
of any shares of any class, or any security convertible into shares of any      
class, having rights senior to the Series H Preferred Shares with respect to the
payment of dividends or the distribution of assets or amounts upon liquidation, 
dissolution or winding up of Duke.                                              

  Except as provided above and is required by applicable law, the holders of
Series H Preferred Shares are not entitled to vote on any merger or             
consolidation involving Duke, on any share exchange or on a sale of all or      
substantially all of the assets of Duke.

THE DUKE DIRECTORS' STOCK OPTION PROPOSAL 

  Subject to shareholder approval, Duke's Board has approved and adopted the
1999 Directors' Stock Option and Dividend Increase Unit Plan of Duke Realty     
Investments, Inc. (the "Directors' Plan") as of January 1, 1999. To become      
effective, the Directors' Plan must be approved by Duke's shareholders. The     
Board believes that the Directors' Plan, when combined with other compensation  
paid to the directors, will provide the directors with a competitive            
compensation package that will further align the interests of the directors with
the interests of Duke's shareholders.                                           

A summary of the material features of the Directors' Plan follows. This 
summary is subject in all respects to the actual plan document, a copy of which 
is contained in Annex F to this joint proxy statement and prospectus.           

If the merger is not consummated but this proposal is adopted, the      
Directors' Plan will take effect with respect to Duke. If the merger is         
consummated, the Directors' Plan will take effect with respect to the combined  
company.                                                                        

MATERIAL FEATURES OF THE DIRECTORS' PLAN                                        

The Directors' Plan provides for the granting of (1) options to purchase
common shares ("Director Options"); and (2) dividend increase units ("Director  
DIUs") to certain directors ("Eligible Directors")

for a period of 10 years commencing January 1, 1999. A director is an Eligible  
Director if, for the year of grant, such director has not and will not receive a
grant of stock options under any other Duke sponsored plan. The Directors' Plan 
will expire on December 31, 2008 except as to outstanding Director Options and  
Director DIUs that shall remain in effect until they have been exercised,       
terminated or expired. A total of 500,000 common shares may be issued under the 
plan.                                                                           

  During the term of the plan, each Eligible Director will receive an annual
grant of 2,500 Director Options and Director DIUs on the date of the first      
executive compensation committee meeting of each calendar year. However, for the
1999 grant only, if an Eligible Director has never previously received a grant  
of stock options under any other Duke sponsored plan, 7,500 Director Options and
Director DIUs shall be granted to such Eligible Director. In accordance with the
terms of the Directors' Plan, and subject to shareholder approval, Ms. Cuneo and
Messrs. Button, Feinsand, Lytle, Peterson, Rogers, and Strauss received grants  
of 7,500 Director Options and Director DIUs on January 26, 1999. On that same   
date, Messrs. Staton and Wynne received grants of 2,500 Director Options and    
Director DIUs.                                                                  

  Each Director Option and Director DIU has a term of 10 years from the date
of grant. For grants made after 1999, the Director Options and Director DIUs    
will vest at a rate of twenty percent (20%) per year on each anniversary of the 
date of grant. For 1999 grants, each Director Option and Director DIU will vest 
at a rate of twenty percent (20%) per year commencing on the first anniversary  
of the date the director became a director.                                     

  The exercise price of each Director Option shall not be less than the fair
market value of a common share as of the date of grant.                         

    The value of each Director DIU at the date of exercise will be determined by
calculating the dividend yield on Duke's common shares at the date the Director 
DIU is granted and dividing the increase in Duke's annualized dividend from the 
date of grant to the date of exercise by such dividend yield. Director DIUs may 
be exercised by a director only to the extent that such director has exercised  
an equivalent number of Director Options granted on the same date as the DIUs.  

  Any amounts payable to a director upon the exercise of a Director DIU will
be made in a single lump sum payment in the form of common shares. The number of
shares to be issued will be based on the fair market value of the common shares 
at the time of exercise. In the event of a change of control of Duke, each      
director will be entitled to receive, within 90 days of the date of change in   
control, a lump sum payment in cash equal to the value of the Director DIUs at  
the date of the change of control.                                              

    If an optionee's position as a director terminates for any reason other than
for cause (as defined), total disability, death, retirement on or after         
attaining the age of 65, or a change in control of Duke, any outstanding options
that were exercisable on the date of termination will terminate 90 days after   
the date of termination. If a director is terminated for cause, all outstanding 
options will expire on the date of termination. If termination occurs because of
death or total disability, all outstanding options remain exercisable for a     
period of one year from the date of termination. If termination occurs because  
of retirement or a change in control, the options may be exercised at any time  
prior to ten (10) years after the date of grant. In the event of the death,     
total disability or retirement (on or after attaining age 65) of the director or
a change in control of Duke, all outstanding options become immediately         
exercisable.                                                                    

The Board of Directors may, at any time, without the approval of the    
shareholders of Duke, alter, amend, modify, suspend or discontinue the          
Directors' Plan except for any such alterations which would (1) increase the    
aggregate number of options and units that may be granted under the plan (except
to the extent otherwise provided for as a result of stock dividends, splits,    
combinations or other changes of shares described in the plan document); (2)    
decrease the minimum exercise price; (3) extend the term of the plan or change  
the term during which any Director Option or Director DIU may be exercised; (4) 
change the transferability restrictions; (5) change the manner of determining   
the option price, the calculation of unit

value or the method of payment of units; (6) change the class of individuals    
eligible for grants; or (7) change the number of common shares authorized for   
issuance under the plan.                                                        

FEDERAL INCOME TAX CONSEQUENCES OF THE DIRECTORS' PLAN                          

  The Director Options granted under the Directors' Plan will not qualify as
incentive stock options within the meaning of Section 422 of the Internal       
Revenue Code. The Directors will recognize no taxable income and no tax         
deduction is allowable to Duke or its subsidiaries at the time an option is     
granted. At the time a Director Option is exercised, the Director will recognize
ordinary income and Duke or its subsidiaries will be entitled to a compensation 
expense deduction equal to the excess of the fair market value of the shares on 
the date the option is exercised over the exercise price of the shares. The fair
market value of the stock at the time of exercise is the basis for the          
determination of capital gain or loss upon the director's subsequent disposition
of the shares.                                                                  

At the time a Director DIU is exercised, the participant will recognize 
ordinary income, and Duke or its subsidiaries will be entitled to a compensation
expense deduction equal to the value of the common shares transferred to the    
Director.                                                                       

Duke's Board of Directors unanimously recommends the approval of the    
Directors' Plan, and therefore recommends a vote "FOR" the Duke Directors' Stock
Option Proposal. The Directors' Stock Option Proposal requires the affirmative  
vote of a majority of the votes cast by the holders of common shares at the     
meeting.                                                                        

THE DUKE SALARY REPLACEMENT PROPOSAL

    Subject to shareholder approval, the Duke Board has approved and adopted the
1999 Salary Replacement Stock Option and Dividend Increase Unit Plan of Duke    
Realty Investments, Inc. (the "Salary Replacement Plan") as of January 1, 1999. 
To become effective, the plan must be approved by Duke's shareholders.          

Under the Salary Replacement Plan, key employees of Duke will have the  
opportunity to receive stock options and dividend increase units in lieu of     
receiving other compensation. The intent of the Salary Replacement Plan is to   
further link compensation earned by key employees to Duke's stock performance   
and dividend paying capacity. Accordingly, the Board believes that the Salary   
Replacement Plan will further align Duke's compensation programs with           
shareholder interests.                                                          

  A summary of the material features of the Salary Replacement Plan follows.
This summary is subject in all respects to the actual plan document, a copy of  
which is contained in Annex G to this joint proxy statement and prospectus.     

 If the merger is not consummated but this proposal is adopted, the Salary
Replacement Plan will take effect with respect to Duke. If the merger is        
consummated, the Salary Replacement Plan will take effect with respect to the   
combined company.                                                               

MATERIAL FEATURES OF THE SALARY REPLACEMENT PLAN                                

The Salary Replacement Plan provides for the granting of (1) options to 
purchase common shares ("Salary Replacement Options"); and (2) dividend increase
units ("Salary Replacement DIUs") to key employees for a period of 10 years     
commencing January 1, 1999. The Salary Replacement Plan will expire on December 
31, 2008 except as to outstanding Salary Replacement Options and Salary         
Replacement DIUs which shall remain in effect until they have been exercised,   
terminated or expired. A total of 500,000 common shares may be issued under the 
plan.                                                                           

During the term of the plan, each eligible employee may elect to receive
Salary Replacement Options and Salary Replacement DIUs in lieu of all or a      
portion of their annual salary, bonus or Duke's

Shareholder Value Plan award. The number of Salary Replacement Options and      
Salary Replacement DIUs granted for the foregone compensation will be based on  
the executive compensation committee's determination of the value of an option  
and DIU on the date of grant.                                                   

  Each Salary Replacement Option and Salary Replacement DIU will have a term
of 10 years from the date of grant and will immediately vest on the date of     
grant. The exercise price of each Salary Replacement Option shall not be less   
than the fair market value of a common share as of the date of grant.           

The value of each Salary Replacement DIU on the date of exercise will be
determined by calculating the dividend yield on Duke's common shares as of the  
date of the Salary Replacement DIU is granted and dividing the increase in      
Duke's annualized dividend from the date of grant to the date of exercise by    
such dividend yield. Salary Replacement DIUs may be exercised only to the extent
that a participant has exercised an equivalent number of Salary Replacement     
Options granted on the same date as the DIUs.                                   

Any amounts payable to a participant upon the exercise of a Salary      
Replacement DIU will be made in a single lump sum payment in the form of common 
shares. The number of shares to be issued will be based on the fair market value
of the common shares at the time of exercise. In the event of a change of       
control of Duke, each participant will be entitled to receive, within 90 days of
the date of change in control, a lump sum payment in cash equal to the value of 
the Salary Replacement DIUs at the date of change of control.                   

    If a participant's employment terminates for any reason other than for cause
(as defined), any outstanding options that were exercisable on the date of      
termination will terminate (2) years after the date of termination. If a        
participant is terminated for cause, all outstanding options will expire on the 
date of termination.                                                            

The Board of Directors may, at any time, without the approval of the    
shareholders of Duke, alter, amend, modify, suspend or discontinue the Salary   
Replacement Plan, except for any such alterations which would (1) decrease the  
minimum exercise price; (2) extend the term of the plan or change the term      
during which any Salary Replacement Option or Salary Replacement DIU may be     
exercised; (3) change the class of individuals eligible for grants; (4) change  
the number of shares of common shares authorized for issuance under the plan; or
(5) withdraw administration of the plan from the executive compensation         
committee or the Board of Directors.                                            

FEDERAL INCOME TAX CONSEQUENCES OF THE SALARY REPLACEMENT PLAN                  

The Salary Replacement Options granted under the Salary Replacement Plan
will not qualify as incentive stock options within the meaning of Section 422 of
the Internal Revenue Code. The participants will recognize no taxable income and
no tax deduction is allowable to Duke or its subsidiaries at the time an option 
is granted. At the time a Salary Replacement Option is exercised, a participant 
will recognize ordinary income, in the form of compensation, and Duke or its    
subsidiaries will be entitled to a compensation expense deduction equal to the  
excess of the fair market value of the shares on the date the option is         
exercised over the exercise price of the shares. The fair market value of the   
stock at the time of exercise is the basis for the determination of capital gain
or loss upon the participant's subsequent disposition of the shares.            

At the time a Salary Replacement DIU is exercised, the participant will 
recognize ordinary income in the form of compensation, and Duke or its          
subsidiaries will be entitled to a compensation expense deduction equal to the  
value of the common shares transferred to the participant.                      

The Board of Directors unanimously recommends the approval of the Salary
Replacement Plan, and therefore recommends a vote "FOR" the Duke Salary         
Replacement Proposal. The Duke Salary Replacement Proposal requires the         
affirmative vote of a majority of votes cast by the holders of common shares at 
the meeting.

THE DUKE DIRECTORS' STOCK PAYMENT PLAN PROPOSAL 

 Duke's Board of Directors has adopted an amendment to the 1996 Directors'
Stock Payment Plan of Duke Realty Investments, Inc. (the "Directors' Stock      
Payment Plan") and is recommending the approval of the amendment by the         
shareholders. The amendment would increase the number of common shares available
for issuance under the Directors' Stock Payment Plan. If approved by the        
shareholders, the number of common shares available for issuance would increase 
by 100,000.                                                                     

The purpose of the Directors' Stock Payment Plan is to increase the     
proprietary interest in Duke of its non-employee directors. The Directors' Stock
Payment Plan covers only the non-employee directors of Duke and is administered 
by Duke's Compensation Committee.                                               

    The Directors Stock Payment Plan was adopted by Duke's Board in October 1995
and approved by the shareholders in April 1996. The Directors' Stock Payment    
Plan currently permits the issuance of up to 40,000 shares, of which 31,800     
shares have been issued. Absent approval of this proposal by the shareholders,  
Duke will not be able to continue to issue common shares to the directors in    
amounts contemplated by the plan.                                               

Duke's Board of Directors believes that adding more common shares to the
Directors' Stock Payment Plan will help Duke continue to align the interests of 
the directors with the interests of Duke's shareholders and to compensate its   
non-employee directors in a manner that is competitive with companies comparable
to Duke.                                                                        

 The following is a description of the material features of the Directors'
Stock Payment Plan. A copy of the plan document and the amendment to the plan   
are set out in full in Annex H to this joint proxy statement and prospectus.    

MATERIAL FEATURES OF THE DIRECTORS' STOCK PAYMENT PLAN                          

   Under the Directors' Stock Payment Plan, each non-employee director of Duke
is entitled to receive as compensation for services 300 shares of common stock  
of Duke for each full calendar quarter during which he or she is actively       
serving as a director of Duke. In the event a participant is a director for less
than a full calendar quarter, the number of shares such participant is entitled 
to receive will be prorated for the portion of the quarter of active service.   

FEDERAL INCOME TAX CONSEQUENCES                                                 

    The participants will recognize ordinary income and Duke will be entitled to
an income tax deduction equal to the fair market value of the Duke's common     
stock at the time of the transfer of the shares.                                

Duke's Board of Directors unanimously recommends the approval of the    
amendment to the Directors' Stock Payment Plan, and therefore recommends a vote 
"FOR" the Duke Directors' Stock Payment Plan Proposal. The Directors' Stock     
Payment Plan Proposal requires the affirmative vote of a majority of the votes  
cast by the holders of common shares at the meeting.

DISCLOSURE OF NEW PLAN BENEFITS 

Awards under the 1999 Directors' Stock Option and Dividend Increase Unit
Plan and the 1996 Directors' Stock Payment Plan are set by formula. The benefits
to be received under the 1999 Salary Replacement Stock Option and Dividend      
Increase Unit Plan are generally indeterminable because all awards are within   
the discretion of the employee. Duke's chief executive officer and its four most
highly compensated executive officers (other than the chief executive officer)  
during the last fiscal year are not eligible to receive benefits under the 1999 
Directors' Stock Option and Dividend Increase Unit Plan and the 1996 Directors' 
Stock Payment Plan, nor have any of these executive officers elected to receive 
benefits under the 1999 Salary Replacement Stock Option and Dividend Increase   
Unit Plan for the 1999 fiscal year. The awards that will be made in Duke's 1999 
fiscal year under such plans if the plan proposals are approved are outlined in 
the following tables.

PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 

(UNAUDITED) 

The following pro forma condensed consolidated financial statements for 
Duke-Weeks Realty Corporation ("Duke-Weeks") include certain pro forma          
adjustments to the historical financial statements of Duke Realty Investments,  
Inc. ("Duke") to reflect the proposed merger (the "Merger") of Duke and Weeks   
Corporation ("Weeks"). The Merger will be accounted for using the purchase      
method of accounting in accordance with Accounting Principles Board Opinion No. 
16. These pro forma condensed consolidated financial statements should be read  
in conjunction with the Duke Form 10-K as of and for the three years ended      
December 31, 1998, and also in conjunction with Weeks' Form 10-K as of and for  
the three years ended December 31, 1998.                                        

  The following pro forma condensed consolidated balance sheet is based upon
the December 31, 1998 consolidated balance sheet of Duke and the December 31,   
1998 consolidated balance sheet of Weeks, presented as if the Merger occurred on
December 31, 1998.                                                              

 The following pro forma condensed consolidated statement of operations is
based upon the consolidated statements of operations for the year ended December
31, 1998 of Duke and Weeks, presented as if the Merger occurred as of January 1,
1998.                                                                           

   The pro forma condensed consolidated financial statements do not purport to
be indicative of the actual financial position or results of operations which   
would have been obtained assuming that the Merger had been completed as set     
forth above, or which may be obtained in the future.

AGREEMENT AND PLAN OF MERGER (the "AGREEMENT"), dated as of February 28,
1999, by and between DUKE REALTY INVESTMENTS, INC., an Indiana corporation      
("DUKE"), and WEEKS CORPORATION, a Georgia corporation ("WEEKS").               

RECITALS

    A. The Boards of Directors of Duke and Weeks each have determined that it is
advisable and in the best interest of their respective companies and            
shareholders that upon the terms and subject to the conditions set forth in this
Agreement, Weeks will merge with and into Duke, with Duke being the surviving   
corporation, in a merger (the "REIT MERGER") in which each issued and           
outstanding share of common stock, par value $.01 per share, of Weeks (the      
"WEEKS COMMON STOCK"), each issued and outstanding share of 8.0% Series A       
Cumulative Redeemable Preferred Stock, par value $.01 per share, of Weeks (the  
"WEEKS SERIES A PREFERRED STOCK") and each issued and outstanding share, if any,
of 8.625% Series D Cumulative Redeemable Preferred Stock, par value $.01 per    
share, of Weeks (the "WEEKS SERIES D PREFERRED STOCK" and together with the     
Weeks Series A Preferred Stock, the "WEEKS PREFERRED STOCK") will be converted  
into the right to receive the applicable Merger Consideration (as defined       
below).                                                                         

    B. Duke, as managing general partner of Duke Limited Partnership, an Indiana
limited partnership ("DUKE OP"), and Weeks, as general partner (through a wholly
owned subsidiary) of Weeks, L.P., a Georgia limited partnership ("WEEKS OP"),   
each has determined that it is advisable and in the best interest of their      
respective partnerships and partners that upon the terms and subject to the     
conditions set forth in an agreement and plan of merger between Duke OP and     
Weeks OP executed on the date hereof, a copy of which is attached as Exhibit A  
hereto (the "OP MERGER AGREEMENT"), Weeks OP will merge with and into Duke OP   
with Duke OP being the surviving partnership in such merger (the "OP MERGER").  

  C. The parties intend that for federal income tax purposes the REIT Merger
will qualify as a tax-free reorganization under Section 368(a) of the Internal  
Revenue Code of 1986, as amended (the "CODE"), and that, following the REIT     
Merger, Duke will continue to be subject to taxation as a real estate investment
trust (a "REIT") within the meaning of the Code.                                

   D. Contemporaneously with the execution and delivery of this Agreement, (i)
certain holders of Weeks Common Stock named in Schedule A hereto and certain    
holders of limited partnership interests in Weeks OP named in Schedule A hereto 
have entered into agreements, each substantially in the form of Exhibit B hereto
(the "WEEKS VOTING AGREEMENTS"), with Duke and Duke OP pursuant to which, among 
other things, those holders have granted to Duke irrevocable proxies to vote    
their shares and partnership interests in favor of the REIT Merger, this

In consideration of the representations, warranties, covenants and      
agreements contained in this Agreement, the parties agree as follows:           

ARTICLE I 
THE REIT MERGER 

Section 1.1.  THE REIT MERGER.                                          

(a) Upon the terms and subject to the conditions set forth in this      
Agreement, at the Effective Time (as hereinafter defined), Weeks shall be merged
with and into Duke in accordance with the Indiana Business Corporation Law (the 
"IBCL") and the Georgia Business Corporation Code (the "GBCC," and together with
the IBCL, the "GOVERNING LAWS"), whereupon the separate corporate existence of  
Weeks shall cease and Duke shall continue as the surviving corporation (the     
"SURVIVING CORPORATION").                                                       

   (b) The REIT Merger shall have the effects set forth in the Governing Laws.
Accordingly, from and after the Effective Time, the Surviving Corporation shall 
possess all the rights, privileges, powers and franchises and be subject to all 
of the restrictions, disabilities, liabilities and duties of Duke and Weeks.    

   Section 1.2.  CLOSING.  The closing of the REIT Merger (the "CLOSING") will
take place at 10:00 a.m. New York City time on the second business day after    
satisfaction or waiver of the conditions set forth in Article VI (the "CLOSING  
DATE"), at the offices of Rogers & Wells LLP, 200 Park Avenue, New York, New    
York 10166, unless another date or place is agreed to in writing by the parties.

Section 1.3.  EFFECTIVE TIME.  On the Closing Date, the parties shall   
execute and file Articles of Merger or other appropriate documents in accordance
with the Governing Laws, and shall make all other filings or recordings required
with respect to the REIT Merger under the Governing Laws. The REIT Merger shall 
become effective one day after the day a certificate of merger or other         
appropriate documents for the OP Merger have been duly filed with the Secretary 
of State of Indiana and the Secretary of State of Georgia, or at such other time
or times as may be agreed by Duke and Weeks and specified in the Articles of    
Merger (the time the REIT Merger becomes effective being the "EFFECTIVE TIME"), 
it being understood that the parties shall cause the Effective Time to occur as 
soon as practicable after the Closing Date but in any event at least one day    
after the effective time of the OP Merger.                                      

Section 1.4.  CHARTER AND BY-LAWS.  The articles of incorporation and   
by-laws of Duke, amended and restated substantially in the forms set forth in   
Exhibits E and F hereto, shall become the articles of incorporation (the        
"CHARTER") and by-laws (the "BY-LAWS") of the Surviving Corporation upon the    
Effective Time until further amended in accordance with applicable Indiana law; 
PROVIDED, HOWEVER, that if the Duke Special Charter Proposal (as defined below) 
is not approved at the Duke Shareholders Meeting (as defined in Section 5.1(b)) 
by the affirmative vote of at least 80% of Duke's issued and outstanding shares 
of capital stock ("80% DUKE APPROVAL"), the Charter and By-laws upon the        
Effective Time shall be substantially in the forms set forth in Exhibits G and H

"DUKE SPECIAL CHARTER PROPOSAL" is the proposal, to be presented at the Duke    
Shareholders Meeting, to amend Duke's Charter to (i) increase the size of Duke's
Board of Directors to a minimum of five and a maximum of 23 and (ii) delete the 
references contained in Article XII of Duke's Charter to Section 7.01 of the    
Charter.                                                                        

Section 1.5.  DIRECTORS.  Immediately following the Effective Time, the 
Board of Directors of the Surviving Corporation (the "BOARD") and certain       
committees of the Board shall consist of the persons named on Schedule D hereto,
each of whom shall be a member of the class indicated on Schedule D; PROVIDED,  
HOWEVER, that if the Duke Special Charter Proposal is not approved at the Duke

of the Board shall consist immediately following the Effective Time of the      
persons named on Schedule E hereto, each of whom shall

    Section 1.6.  OFFICERS.  The executive officers of the Surviving Corporation
immediately following the Effective Time shall include the persons named on

 (a) CAPITAL STOCK OWNED BY WEEKS OR ITS SUBSIDIARIES. As of the Effective
Time, any shares of capital stock of Weeks that are owned by Weeks or any Weeks 
Subsidiary automatically shall be cancelled and retired and all rights with     
respect thereto shall cease to exist, and no consideration shall be delivered in
exchange therefor.                                                              

(b) CONVERSION OF WEEKS CAPITAL STOCK INTO DUKE CAPITAL STOCK. At the   
Effective Time, except as provided in Section 2.1(a), (i) each issued and       
outstanding share of Weeks Common Stock shall be converted by virtue of the REIT
Merger, automatically and without any action on the part of the holder thereof, 
into the right to receive from the Surviving Corporation 1.38 (the "EXCHANGE    
RATIO"") fully paid and nonassessable shares of common stock, par value $.01 per
share, of Duke ("DUKE COMMON STOCK"), (ii) each issued and outstanding share of 
Weeks Series A Preferred Stock shall be converted by virtue of the REIT Merger, 
automatically and without any action on the part of the holder thereof, into the
right to receive from the Surviving Corporation one fully paid and nonassessable
preference share (a "SERIES F PREFERENCE SHARE"), representing 1/1000 of a share
of 8.0% Series F Cumulative Redeemable Preferred Stock, par value $.01 per      
share, of Duke ("DUKE SERIES F PREFERRED STOCK") and (iii) each issued and      
outstanding share of Weeks Series D Preferred Stock (if any) shall be converted,

PREFERENCE SHARES"), representing 1/1000 of a share of 8.625% Series H          
Cumulative Redeemable Preferred Stock, par value $0.01 per share, of Duke ("DUKE
SERIES H PREFERRED STOCK", and together with the Duke Series F Preferred Stock,

Common Stock and Weeks Preferred Stock outstanding immediately prior to the     
Effective Time shall cease to be outstanding and automatically shall be         
cancelled and retired and all rights with respect thereto shall cease to exist,

respect thereto, except the right to receive, upon surrender of such Certificate
in accordance with Section 2.2(c), a certificate or certificates representing   
the shares of Duke Common Stock or New Duke Preference Shares, as applicable,   
into which those shares are converted pursuant to this Section 2.1(b) and any   
cash in lieu of fractional shares of Duke Common Stock to be issued or paid in  
consideration therefor upon surrender of such certificate (the "MERGER          
CONSIDERATION") and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.2(d), in each case without interest and less any 
required withholding taxes. Notwithstanding the foregoing, the rights of each   
stockholder of the Surviving Corporation under this Section 2.1 will be subject 
to the ownership limitations and other related provisions contained in the      
Charter.

(c) SHARES OF DUKE CAPITAL STOCK. Upon the Effective Time, each share of
capital stock of Duke outstanding immediately prior to the Effective Time shall 
remain outstanding and shall represent one share of validly issued, fully paid  
and nonassessable capital stock of the same class and designation.              

Section 2.2.  EXCHANGE OF CERTIFICATES.                                 

  (a) EXCHANGE AGENT. Prior to the Effective Time, Duke shall appoint a bank
or trust company that is reasonably acceptable to Weeks to act as exchange agent
(the "EXCHANGE AGENT") for the exchange of the Merger Consideration for         
Certificates representing issued and outstanding Weeks Common Stock and Weeks   
Preferred Stock.                                                                

    (b) DUKE TO PROVIDE MERGER CONSIDERATION. Duke shall provide, or cause to be
provided, to the Exchange Agent on and after the Effective Time from time to    
time as required pursuant to Section 2.2(c) and 2.2(g), for the benefit of the  
holders of Weeks Common Stock and Weeks Preferred Stock, certificates           
representing the shares of Duke Common Stock and New Duke Preferred Stock into  
which the issued and outstanding shares of Weeks Common Stock and Weeks         
Preferred Stock are converted pursuant to Section 2.1(b), together with the cash
payable in respect of fractional shares pursuant to Section 2.2(g).             

(c) EXCHANGE PROCEDURE. As soon as reasonably practicable after the     
Effective Time, the Exchange Agent shall mail to each holder of record of a     
Certificate or Certificates whose shares were converted into the right to       
receive the Merger Consideration pursuant to Section 2.1, (i) a letter of       
transmittal (which shall specify that delivery shall be effected, and risk of   
loss and title to the Certificates shall pass, only upon delivery of the        
Certificates to the Exchange Agent and shall be in a form and have such other   
provisions as Duke may reasonably specify) and (ii) instructions for use in     
effecting the surrender of the Certificates, in exchange for the applicable     
Merger Consideration. Upon surrender of a Certificate for cancellation to the   
Exchange Agent or to such other agent or agents as may be appointed by Duke,    
together with such letter of transmittal, duly executed, and such other         
documents as may reasonably be required by the Exchange Agent, the holder of    
such Certificate shall be entitled to receive in exchange therefor the          
applicable Merger Consideration and any dividends or other distributions to     
which such holder is entitled pursuant to Section 2.2(d), and the Certificate so
surrendered shall forthwith be cancelled. In the event of a transfer of         
ownership of Weeks Common Stock or Weeks Preferred Stock which is not registered
in the transfer records of Weeks, payment may be made to a person other than the
person in whose name the Certificate so surrendered is registered if such       
Certificate shall be properly endorsed or otherwise be in proper form for       
transfer and the person requesting such payment either shall pay any transfer or
other taxes required by reason of such payment being made to a person other than
the registered holder of such Certificate or establish to the satisfaction of   
Duke that such tax or taxes have been paid or are not applicable. Until         
surrendered as contemplated by this Section 2.2, each Certificate shall be      
deemed at any time after the Effective Time to represent only the right to      
receive upon such surrender the applicable Merger Consideration, without        
interest, into which the shares theretofore represented by such Certificate     
shall have been converted pursuant to Section 2.1 and any dividends or other    
distributions to which such holder is entitled pursuant to Section 2.2(d). No   
interest will be paid or will accrue on the applicable Merger Consideration upon
the surrender of any Certificate or on any cash payable pursuant to Section     
2.2(d) or Section 2.2(g).                                                       

(d) RECORD DATES; DISTRIBUTIONS WITH RESPECT TO UNEXCHANGED SHARES.     

    (i) To the extent reasonably necessary to ensure satisfaction of the
   requirements of Section 857(a)(1) of the Code for the taxable year of Weeks
ending at the Effective Time, Weeks shall declare a dividend (the "FINAL
    WEEKS DIVIDEND") to holders of shares of Weeks Common Stock, the record date
  for which shall be the close of business on the last business day prior to
    the Effective Time, in an amount equal to the minimum dividend sufficient to
   permit Weeks to satisfy such requirements. If Weeks determines it necessary
   to declare the Final Weeks Dividend, it shall notify Duke at least ten (10)
days prior to the date for the Weeks Shareholders Meeting (as defined in
  Section 5.1(b)), and Duke shall declare a dividend per share to holders of
Duke Common Stock, the

 record date for which shall be the close of business on the last business
day prior to the Effective Time, in an amount per share equal to the    
quotient obtained by dividing (x) the Final Weeks Dividend per share of 
 Weeks Common Stock paid by Weeks by (y) the Exchange Ratio. The dividends
payable hereunder to holders of Weeks Common Stock shall be paid upon   
presentation of the Certificates of Weeks Common Stock for exchange in  
accordance with this Article II.                                        

    (ii) No dividends or other distributions with respect to Duke Common
Stock or New Duke Preferred Stock with a record date after the Effective
Time shall be paid to the holder of any unsurrendered Certificate with  
 respect to the shares represented thereby, and no cash payment in lieu of
fractional shares shall be paid to any such holder pursuant to Section  
  2.2(g), in each case until the surrender of such Certificate in accordance
with this Article II. Subject to the effect of applicable abandoned     
property, escheat or similar laws, following surrender of any such      
 Certificate there shall be paid to the holder of such Certificate without
   interest, (A) at the time of such surrender, the amount of any cash payable
  in lieu of any fractional share of Weeks Common Stock to which such holder
is entitled pursuant to Section 2.2(g) and (B) if such Certificate is   
   exchangeable for one or more whole shares of Duke Common Stock, or New Duke
   Preferred Stock, (x) at the time of such surrender, the amount of dividends
or other distributions with a record date after the Effective Time      
  theretofore paid with respect to such whole shares of Duke Common Stock or
New Duke Preferred Stock, and (y) at the appropriate payment date, the  
amount of dividends or other distributions with a record date after the 
Effective Time but prior to such surrender and with a payment date      
 subsequent to such surrender payable with respect to such whole shares of
Duke Common Stock or New Duke Preferred Stock.                          

(e) NO FURTHER OWNERSHIP RIGHTS IN WEEKS CAPITAL STOCK. All Merger      
Consideration paid upon the surrender of Certificates in accordance with the    
terms of this Article II (and any cash paid pursuant to Section 2.2(g)) shall be
deemed to have been paid in full satisfaction of all rights pertaining to the   
shares of Weeks Common Stock and Weeks Preferred Stock theretofore represented  
by such Certificates; subject, however, to the obligation of Weeks to pay,      
without interest, any dividends or make any other distributions with a record   
date prior to the Effective Time which may have been declared or made by Weeks  
on such shares in accordance with the terms of this Agreement or prior to the   
date of this Agreement and which remain unpaid at the Effective Time and have   
not been paid prior to such surrender, and there shall be no further            
registration of transfers on the stock transfer books of Weeks of the shares of 
Weeks Common Stock or Weeks Preferred Stock which were outstanding immediately  
prior to the Effective Time. If, after the Effective Time, Certificates are     
properly presented to the Surviving Corporation they shall be cancelled and     
exchanged as provided in this Article II.                                       

   (f) UNCLAIMED MERGER CONSIDERATION. Any portion of the Merger Consideration
delivered to the Exchange Agent pursuant to this Agreement that remains         
unclaimed for six months after the Effective Time shall be redelivered by the   
Exchange Agent to the Surviving Corporation, upon demand, and any holders of    
Certificates who have not theretofore complied with Section 2.2(b) shall        
thereafter look only to the Surviving Corporation for delivery of the Merger    
Consideration, subject to applicable abandoned property, escheat and other      
similar laws. The Surviving Corporation shall have no liability to any holder of
shares of Weeks Common Stock or Weeks Preferred Stock for Merger Consideration  
delivered to a public official pursuant to any applicable abandoned property,   
escheat or similar law. Any Merger Consideration remaining unclaimed by any     
holder of shares of Weeks Common Stock or Weeks Preferred Stock on the day      
immediately prior to the time such amounts otherwise would escheat to or become 
the property of any governmental entity shall, to the extent permitted by law,  
become the property of the Surviving Corporation, free and clear of any claim or
interest of any Persons previously entitled thereto.

(g) NO FRACTIONAL SHARES.                                               

   (i) No certificates or scrip representing fractional shares of Duke
Common Stock shall be issued upon the surrender for exchange of         
    Certificates, and such fractional share interests will not entitle the owner
thereof to vote, to receive dividends or to any other rights of a       
stockholder of Duke.                                                    

       (ii) Notwithstanding any other provision of this Agreement, each holder
 of shares of Weeks Common Stock who would otherwise have been entitled to
receive a fraction of a share of Duke Common Stock (after taking into   
account all Certificates delivered by such holder) shall receive, upon  
 surrender of such holder's Certificates in accordance with Section 2.1, a
    cash payment in lieu of such fractional shares of Duke Common Stock equal to
  the same fractional proportion of the arithmetic mean of the closing sales
 price of a share of Duke Common Stock on the New York Stock Exchange (the
 "NYSE") on each of the ten trading days immediately preceding the Closing
Date.                                                                   

 (h) WITHHOLDING. The Surviving Corporation or the Exchange Agent shall be
entitled to deduct and withhold from the Merger Consideration otherwise payable 
pursuant to this Agreement to any holder of shares of Weeks Common Stock or     
Weeks Preferred Stock such amounts as the Surviving Corporation or the Exchange 
Agent is required to deduct and withhold with respect to the making of such     
payment under the Code, or any provision of state, local or foreign tax law. To 
the extent that amounts are so withheld by the Surviving Corporation or the     
Exchange Agent, such withheld amounts shall be treated for all purposes of this 
Agreement as having been paid to the holder of the shares of Weeks Common Stock 
or Weeks Preferred Stock, as the case may be, in respect of which such deduction
and withholding was made by the Surviving Corporation or the Exchange Agent.    

(i) NO DISSENTERS' RIGHTS. No dissenters' or appraisal rights shall be  
available with respect to the REIT Merger.                                      

ARTICLE III

   Section 3.1.  REPRESENTATIONS AND WARRANTIES OF WEEKS.  Except as set forth
in the letter of even date herewith (with sections organized in accordance with 
Section 9.9) signed by the President or Chief Executive Officer and the Chief   
Financial Officer of Weeks and delivered to Duke prior to the execution hereof  
(the "WEEKS DISCLOSURE LETTER"), Weeks represents and warrants to Duke as       
follows:                                                                        

(a) ORGANIZATION, STANDING AND CORPORATE POWER OF WEEKS. Weeks is a     
corporation duly organized and validly existing under the laws of Georgia and   
has the requisite corporate power and authority to carry on its business as now 
being conducted. Weeks is duly qualified or licensed to do business and is in   
good standing in each jurisdiction in which the nature of its business or the   
ownership, leasing of its properties or management of properties for others     
makes such qualification or licensing necessary, other than in such             
jurisdictions where the failure to be so qualified or licensed, individually or 
in the aggregate, would not have a material adverse effect on the business,     
properties, financial condition or results of operations of Weeks and the Weeks 
Subsidiaries taken as a whole (a "WEEKS MATERIAL ADVERSE EFFECT").              

(b) WEEKS SUBSIDIARIES; INTERESTS IN OTHER PERSONS.                     

    (i) Section 3.1(b)(i) of the Weeks Disclosure Letter sets forth each
   Weeks Subsidiary and the ownership interest therein of Weeks and each other

and nonassessable and are not subject to any preemptive rights, and are 
 owned by Weeks, by another Weeks Subsidiary or by Weeks and another Weeks
Subsidiary, free and clear of all pledges, claims, liens, charges,      
encumbrances and security interests of any kind or nature whatsoever

Weeks Subsidiary, including Weeks OP, that is a partnership, limited    
   liability company or trust is duly organized and validly existing under the
laws of its jurisdiction of organization and has the requisite power and

    Subsidiary, including Weeks OP, is duly qualified or licensed to do business
and is in good standing in each jurisdiction in which the nature of its 
business or the ownership, leasing of its properties or management of   
    properties for others makes such qualification or licensing necessary, other
    than in such jurisdictions where the failure to be so qualified or licensed,
 individually or in the aggregate, would not have a Weeks Material Adverse
Effect.

the date of this Agreement greater than $250,000 in any Person or which 
represents 5% or more of the outstanding voting power, capital stock or 
  other ownership interest of any class in any Person. Neither Weeks nor any
Weeks Subsidiary is in material default of any provision of any         
 organizational documents governing or otherwise relating to its rights in
    any Weeks Other Interest. All such organizational documents are set forth in
   Section 3.1(b)(ii) of the Weeks Disclosure Letter and are in full force and
effect.

authorization of, or registration, declaration or filing with, any federal,

is required by or with respect to Weeks or any Weeks Subsidiary (including Weeks

contemplated by this Agreement, (ii) the filing of the Articles of Merger for

authorizations, registrations, declarations and filings as are set forth in     
Section 3.1(d) of the Weeks Disclosure Letter or (A) as may be required under   
(x) federal, state, local or foreign environmental laws or (y) the "BLUE SKY"   
laws of various states or (B) which, if not obtained or made, would not prevent 
or delay in any material respect the consummation of any of the transactions    
contemplated by this Agreement or the OP Merger Agreement or otherwise prevent  
Weeks or Weeks OP from performing their obligations under this Agreement or the 
OP Merger Agreement in any material respect or have, individually or in the     
aggregate, a Weeks Material Adverse Effect.

Weeks OP have filed all required reports, schedules, forms, statements and other
documents with the SEC since January 1, 1995 and August 4, 1997, respectively

than preliminary materials or materials that were subsequently amended), as of  
their respective filing dates, complied in all material respects with all       
applicable requirements of the Securities Act of 1933, as amended (the          
"SECURITIES ACT") and the Exchange Act and, in each case, the rules and         
regulations promulgated thereunder applicable to such Weeks SEC Documents. None 
of the Weeks SEC Documents at the time of filing contained any untrue statement 
of a material fact or omitted to state any

material fact required to be stated therein or necessary in order to make the   
statements therein, in light of the circumstances under which they were made,   
not misleading, except to the extent such statements have been amended, modified
or superseded by later filed Weeks SEC Documents. None of the Weeks SEC         
Documents is the subject of any confidential treatment request by Weeks or Weeks
OP. Section 3.1(e) of the Weeks Disclosure Letter lists all of the Weeks SEC    
Documents filed with the SEC since January 1, 1998. The consolidated financial  
statements of Weeks and Weeks OP, as applicable, included in the Weeks SEC      
Documents complied as to form in all material respects with applicable          
accounting requirements and the published rules and regulations of the SEC with 
respect thereto, have been prepared in accordance with generally accepted       
accounting principles ("GAAP") (except, in the case of interim financial        
statements, as permitted by the applicable rules and regulations of the SEC)    
applied on a consistent basis during the periods involved (except as may be     
indicated in the notes thereto) and fairly presented in all material respects,  
in accordance with the applicable requirements of GAAP, the consolidated        
financial position of Weeks and the Weeks Subsidiaries taken as a whole, as of  
the dates thereof and the consolidated results of operations and cash flows for 
the periods then ended (subject, in the case of interim financial statements, to
normal year-end adjustments). Except as set forth in the Weeks SEC Documents    
filed with the SEC prior to the date of this Agreement, neither Weeks nor any   
Weeks Subsidiary has any liabilities or obligations of any nature (whether      
accrued, absolute, contingent or otherwise) required by GAAP to be set forth on 
a consolidated balance sheet of Weeks or in the notes thereto and which,        
individually or in the aggregate, would have a Weeks Material Adverse Effect.   

  (f) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the Weeks
SEC Documents filed with the SEC prior to the date of this Agreement, since     
December 31, 1997 (the "WEEKS FINANCIAL STATEMENT DATE") and to the date of this
Agreement, Weeks and the Weeks Subsidiaries have conducted their business only  
in the ordinary course and there has not been (i) any change that would have a  
Weeks Material Adverse Effect (a "WEEKS MATERIAL ADVERSE CHANGE"), nor has there
been any occurrence or circumstance that with the passage of time would         
reasonably be expected to result in a Weeks Material Adverse Change, (ii) any   
declaration, setting aside or payment of any dividend or other distribution     
(whether in cash, stock or property) with respect to any of Weeks' capital stock
or any Weeks OP Units, except for (A) regular quarterly dividends (in the case  
of Weeks) not in excess of $.505 per share of Weeks Common Stock and regular    
quarterly dividends on Weeks Series A Preferred Stock not in excess of $.50 per 
share of Weeks Series A Preferred Stock, (B) the payment of a preferred stock   
purchase right dividend pursuant to a Rights Agreement between Weeks and        
Wachovia Bank, N.A. dated May 20, 1998 (the "RIGHTS AGREEMENT"), (C) the Final  
Weeks Dividend and the corresponding Weeks OP distribution, (D) regular         
quarterly distributions (in the case of Weeks OP) of $.505 per Weeks Common OP  
Unit, $.50 per Series A Preferred OP Unit, $.50 per Series C Preferred OP Unit  
and $.5390625 per Series D Preferred OP Unit and (E) any distributions by any   
Weeks Subsidiaries (other than Weeks OP) to other Weeks Subsidiaries or to      
Weeks, in each case, with customary record and payment dates, (iii) any split,  
combination or reclassification of any of Weeks' capital stock or any issuance  
or the authorization of any issuance of any other securities in respect of, in  
lieu of or in substitution for, or giving the right to acquire by exchange or   
exercise, shares of its capital stock or any issuance of an ownership interest  
in, any Weeks Subsidiary, (iv) any damage, destruction or loss, whether or not  
covered by insurance, that has or would have a Weeks Material Adverse Effect, or
(v) any change in accounting methods, principles or practices by Weeks          
materially affecting its assets, liabilities or business, except insofar as may 
have been disclosed in the Weeks SEC Documents filed with the SEC prior to the  
date of this Agreement, or required by a change in GAAP.                        

 (g) LITIGATION. Except as disclosed in the Weeks SEC Documents filed with
the SEC prior to the date of this Agreement, and other than personal injury and 
other routine tort litigation arising from the ordinary course of operations of 
Weeks and the Weeks Subsidiaries which are covered by adequate insurance, there 
is no suit, action or proceeding pending or, to the knowledge of Weeks,         
threatened against or affecting Weeks or any Weeks Subsidiary that, individually
or in the aggregate, could reasonably be expected to (i) have a Weeks Material  
Adverse Effect or (ii) prevent the consummation of any of the

transactions contemplated herein, nor is there any judgment, decree, injunction,
rule or order of any Governmental Entity or arbitrator outstanding against Weeks
or any Weeks Subsidiary having, or which, insofar as reasonably can be foreseen,
in the future would have, any such effect.                                      

(h) ABSENCE OF CHANGES IN BENEFIT PLANS; ERISA COMPLIANCE.              

     (i) Except as disclosed in the Weeks SEC Documents filed with the SEC
prior to the date of this Agreement, since the Weeks Financial Statement
   Date, there has not been any adoption or amendment in any material respect,
or the undertaking of any additional obligation, by Weeks, any Weeks    
Subsidiary or any Weeks ERISA Affiliate (as defined below) of any Weeks 
Benefit Plan (as defined below). For purposes of this Agreement, "Weeks 
    Benefit Plan" shall mean any Employee Plan sponsored or maintained by Weeks,
   any Weeks Subsidiary or any Weeks ERISA Affiliate, or with respect to which
   Weeks, any Weeks Subsidiary or any Weeks ERISA Affiliate has any obligation
to contribute, has liability under or is otherwise a party to, or which 
  otherwise provides benefits for any current or former employees, officers,
directors or other independent contractors (or their dependents and     
beneficiaries) of Weeks or any Weeks Subsidiary. For purposes of this   
Agreement, "Weeks ERISA Affiliate" means any entity required to be      
   aggregated with any of Weeks or any Weeks Subsidiary under Sections 414(b),
(c), (m) or (o) of the Code or Section 4001 of the Employee Retirement  
   Income Security Act of 1974, as amended ("ERISA"). Section 3.1(h)(i) of the
Weeks Disclosure Letter sets forth each Weeks Benefit Plan.             

      (ii) Except as described in the Weeks SEC Documents filed with the SEC
 prior to the date of this Agreement or as would not have a Weeks Material
    Adverse Effect, (A) all Weeks Benefit Plans, including any such plan that is
an "employee benefit plan" as defined in Section 3(3) of ERISA, are in  
 compliance with the terms of such plan and all applicable requirements of
   law, including ERISA and the Code and, without limitation, the requirements
 of ERISA and all tax rules for which favorable tax treatment is intended,
and (B) there are no liabilities or obligations with respect to any such
Weeks Benefit Plan, whether accrued, contingent or otherwise (other than
  obligations by Weeks and the Weeks Subsidiaries to make contributions, and
for such plan to pay benefits and administrative costs, incurred in the 
   ordinary course), nor to the knowledge of Weeks are any such liabilities or
 obligations expected to be incurred. The execution of, and performance of
  the transactions contemplated in, this Agreement will not (either alone or
together with the occurrence of any additional or subsequent events)    
constitute an event under any Weeks Benefit Plan, policy, program,      
arrangement or agreement, trust or loan that will or may result in any  
  payment (whether of severance pay or otherwise), acceleration, forgiveness
  of indebtedness, vesting, distribution, increase in benefits or obligation
  to fund benefits with respect to any employee or director, will not result
in any "golden parachute payments" being due (as defined for purposes of
Section 280G of the Code), or result in any breach or violation of, or a
    default under, any of the Weeks Benefit Plans. The only severance agreements
   or severance policies applicable to Weeks or the Weeks Subsidiaries are the
 agreements and policies specifically referred to in Section 3.1(h)(ii) of
the Weeks Disclosure Letter.                                            

      (iii) Without limiting the foregoing, each Weeks Benefit Plan which is
intended to be tax-qualified under Section 401(a) of the Code has been  
    determined by the IRS to be so qualified and such determination has not been
   modified, revoked or limited, and no circumstances have occurred that would
    adversely affect the tax-qualified status of any such plan. No Weeks Benefit
Plan is or has ever been subject to Part III of Subtitle B of Title I of
   ERISA or Title IV of ERISA or Section 412 of the Code. None of Weeks or any
    Weeks Subsidiary, or any "party in interest" (as defined in Section 3(14) of
    ERISA) or any "disqualified person" (as defined in Section 4975 of the Code)
with respect to any Weeks Benefit Plan, has engaged in a non-exempt     
  "prohibited transaction" within the meaning of Section 4975 of the Code or
Section 406 of ERISA that would have a Weeks Material Adverse Effect.

(i) TAXES.                                                              

    (i) Each of Weeks and each Weeks Subsidiary (including Weeks OP) has
  timely filed all Tax Returns and reports required to be filed by it (after
giving effect to any filing extension properly granted by a Governmental
    Entity having authority to do so). Each such Tax Return is true, correct and
complete in all material respects. Weeks and each Weeks Subsidiary      
  (including Weeks OP) have paid (or Weeks has paid on their behalf), within
  the time and manner prescribed by law, all Taxes that are due and payable.
   The Tax Returns of Weeks and each Weeks Subsidiary have not been audited by
   any Governmental Entity responsible for tax matters (a "TAXING AUTHORITY").
There are no Tax liens upon the assets of Weeks or any Weeks Subsidiary 
    other than liens for Taxes not yet due. The most recent financial statements
    contained in the Weeks SEC Documents filed with the SEC prior to the date of
    this Agreement reflect an adequate reserve for all material Taxes payable by
Weeks and by each Weeks Subsidiary for all taxable periods and portions 
thereof through the date of such financial statements. Since the Weeks  
    Financial Statement Date, Weeks has incurred no liability for federal taxes,
 other than withholding and employment taxes, under the Code or IRS Notice
    88-19. To the knowledge of Weeks, no event has occurred, and no condition or
 circumstance exists, which presents a material risk that any material Tax
described in the preceding sentence will be imposed upon Weeks. No      
   deficiencies for any Taxes have been proposed, asserted or assessed against
  Weeks or any of the Weeks Subsidiaries, and no requests for waivers of the
  time to assess any such Taxes have been granted or are pending. As used in
this Agreement, "TAXES" or "TAX" shall mean any federal, state, local or
 foreign income, gross receipts, license, payroll, employment withholding,
property, recording, stamp, sales, excise or other tax or governmental  
  charges of any nature whatsoever, together with any penalties, interest or
additions thereto and "TAX RETURN" shall mean any return, declaration,  
report, claim for refund, or information return or statement relating to
Taxes, including any schedule or attachment thereto, and including any  
amendment thereof.                                                      

    (ii) Weeks (A) for each taxable year beginning with the taxable year
  ending on December 31, 1994, has been subject to taxation as a REIT within
  the meaning of the Code and has satisfied the requirements to qualify as a
  REIT for such years, (B) has operated, and intends to continue to operate,
    in such a manner as to qualify as a REIT through the end of its taxable year
  ending at the Effective Time, and (C) has not taken or omitted to take any
 action which could reasonably be expected to result in a challenge to its
  status as a REIT, and no such challenge is pending or to Weeks' knowledge,
    threatened. Weeks OP has at all times, and each other Weeks Subsidiary which
   is a partnership or files Tax Returns as a partnership or limited liability
  company for federal income tax purposes has since its acquisition by Weeks
been classified for federal income tax purposes as a partnership or     
   disregarded entity and not as an association taxable as a corporation, or a
  "publicly traded partnership" within the meaning of Section 7704(b) of the
   Code that is treated as a corporation for federal income tax purposes under
 Section 7704(a) of the Code. Neither Weeks nor any Weeks Subsidiary holds
   any asset (x) the disposition of which would be subject to rules similar to
Section 1374 of the Code as announced in IRS Notice 88 19 or (y) that is
 subject to a consent filed pursuant to Section 341(f) of the Code and the
regulations thereunder.                                                 

 (iii) As of the date hereof, Weeks does not have any earnings and
   profits attributable to Weeks or any other corporation in any non-REIT year
within the meaning of Section 857 of the Code.                          

(iv) To the best knowledge of Weeks, Weeks qualifies as a       
    "domestically-controlled" REIT within the meaning of Section 897(h)(4)(B) of
the Code, as of the date hereof.                                        

(j) NO LOANS OR PAYMENTS TO EMPLOYEES, OFFICERS OR DIRECTORS. Except as 
disclosed in the Weeks SEC Documents or as otherwise specifically provided for

(a) ORGANIZATION, STANDING AND CORPORATE POWER OF DUKE. Duke is a       
corporation duly organized and validly existing under the laws of Indiana and   
has the requisite corporate power and authority to carry on its business as now 
being conducted. Duke is duly qualified or licensed to do business and is in    
good standing in each jurisdiction in which the nature of its business or the   
ownership, leasing of its properties or management of properties for others     
makes such qualification or licensing necessary, other than in such             
jurisdictions where the failure to be so qualified or licensed, individually or 
in the aggregate, would not have a material adverse effect on the business,     
properties, financial condition or results of operations of Duke and the Duke   
Subsidiaries, taken as a whole (a "DUKE MATERIAL ADVERSE EFFECT").

and nonassessable and are not subject to any preemptive rights, and are 
owned by Duke, by another Duke Subsidiary or by Duke and another Duke   
 Subsidiary, free and clear of all Liens, and all equity interests in each
  Duke Subsidiary, including Duke OP, that is a partnership (other than Duke

    power and authority to carry on its business as now being conducted and each
    Duke Subsidiary, including Duke OP, that is a partnership, limited liability
 company or trust is duly organized and validly existing under the laws of
  its jurisdiction of organization and has the requisite power and authority
to carry on its business as now being conducted. Each Duke Subsidiary,  
 including Duke OP, is duly qualified or licensed to do business and is in
 good standing in each jurisdiction in which the nature of its business or
the ownership or leasing of its properties makes such qualification or  
  licensing necessary, other than in such jurisdictions where the failure to
    be so qualified or licensed individually or in the aggregate, would not have
an Duke Material Adverse Effect.                                        

     (ii) Except for the capital stock of or other equity interests in the

 or more of the voting power, outstanding capital stock or other ownership
    interest of any class in any Person. Neither Duke nor any Duke Subsidiary is
in material default of any provision of any organizational documents    
 governing or otherwise relating to its rights in any Duke Other Interest.

this Agreement by Duke and the consummation by Duke of the transactions         
contemplated hereby to which Duke is a party have been duly authorized by all   
necessary action on the part of Duke, subject to receipt of the Duke Shareholder

agreement contemplated by this Agreement or the OP Merger Agreement by Duke, as 
the sole general partner of Duke OP, and by Duke OP and the consummation by Duke
OP of the transactions contemplated hereby and by the OP Merger Agreement have  
been duly authorized by all necessary partnership action. This Agreement, the OP

been duly executed and delivered by Duke or Duke OP, as the case may be, and    
constitute the valid and binding obligations of Duke and Duke OP, as the case   
may be, enforceable against Duke or Duke OP in accordance with their terms. The 
execution and delivery of this Agreement, the OP Merger Agreement and the other 
agreements contemplated by this Agreement and the OP Merger Agreement by Duke on
behalf of itself and as general partner of Duke OP do not, and the consummation 
of the transactions contemplated hereby and thereby to which either Duke or Duke
OP is a party and compliance by either Duke or Duke OP with the provisions of   
this Agreement, the OP Merger Agreement and the other agreements contemplated by
this Agreement and the OP Merger Agreement will not, conflict with, or result in
any violation of, or default (with or without notice or lapse of time, or both) 
under, or give rise to a right of termination, cancellation or acceleration of  
any obligation or to loss of a material benefit under, or result in the creation
of any Lien upon any of the properties or assets of Duke or any Duke Subsidiary 
under, (i) the Charter or By-laws or the comparable charter or organizational   
documents or partnership or similar agreement (as the case may be) of any Duke  
Subsidiary, each as amended or supplemented to the date of this Agreement, (ii)

contract, franchise or license applicable to Duke or any Duke Subsidiary or     
their respective properties or assets or (iii) subject to the governmental      
filings and other matters referred to in the following sentence, any Laws       
applicable to Duke or any Duke Subsidiary or their respective properties or     
assets, other than, in the case of clause (ii) or (iii), any such conflicts,    
violations, defaults, rights or Liens that individually or in the aggregate     
would not (x) have a Duke Material Adverse Effect or (y) materially delay or    
prevent the consummation of the REIT Merger or the OP Merger or the transactions
contemplated by this Agreement or the OP Merger Agreement. No consent, approval,
order or authorization of, or registration, declaration or filing with, any     
Governmental Entity is required by or with respect to Duke or any Duke          
Subsidiary (including Duke OP) in connection with the execution and delivery of 
this Agreement, the OP Merger Agreement or the other agreements contemplated by 
this Agreement, by Duke or Duke OP, as the case may be, or the consummation by  
Duke and its Subsidiaries of any of the transactions contemplated hereby, except

Disclosure Letter or (A) as may be required under (x) federal, state or local   
environmental laws or (y) the "blue sky" laws of various states or (B) which, if
not obtained or made, would not prevent or delay in any material respect the    
consummation of the REIT Merger or the OP Merger or any of the transactions     
contemplated by this Agreement or the OP Merger Agreement or otherwise prevent  
Duke or Duke OP from performing its obligations under this Agreement in any     
material respect or have, individually or in the aggregate, a Duke Material     
Adverse Effect.                                                                 

  (e) SEC DOCUMENTS; FINANCIAL STATEMENTS; UNDISCLOSED LIABILITIES. Duke and
Duke OP have filed all required reports, schedules, forms, statements and other

and August 4, 1997, respectively (collectively, the "DUKE SEC DOCUMENTS"). All  
of the Duke SEC Documents (other than preliminary materials or materials that   
were subsequently amended), as of their respective filing dates, complied in all
material respects with all applicable requirements of the Securities Act and the
Exchange Act and, in each case, the rules and regulations promulgated thereunder
applicable to such Duke SEC Documents. None of the Duke SEC Documents at the    
time of filing contained any untrue statement of a material fact or omitted to  
state any material fact required to be stated therein or necessary in order to  
make the statements therein, in light of the circumstances under which they were
made, not misleading, except to the extent such statements have been amended,   
modified or superseded by later filed Duke SEC Documents. None of the Duke SEC  
Documents is the subject of any confidential treatment request by Duke or Duke  
OP. Section 3.2(e) lists all of the Duke SEC Documents filed with the SEC since 
January 1, 1998. The consolidated financial statements of Duke and Duke OP, as  
applicable, included in the Duke SEC Documents complied as to form in all       
material respects with applicable accounting requirements and the published     
rules and regulations of the SEC with respect thereto, have been prepared in    
accordance with GAAP (except, in the case of interim financial statements, as   
permitted by the applicable rules and regulations of the SEC) applied on a      
consistent basis during the periods involved (except as may be indicated in the 
notes thereto) and fairly presented in all material respects, in accordance with
the applicable requirements of GAAP, the consolidated financial position of Duke
and the Duke Subsidiaries, taken as a whole, as of the dates thereof and the    
consolidated results of operations and cash flows for the periods then ended    
(subject, in the case of interim financial statements, to normal year-end       
adjustments). Except as set forth in the Duke SEC Documents filed with the SEC  
prior to the date of this Agreement, neither Duke nor any Duke Subsidiary has   
any liabilities or obligations of any nature (whether accrued, absolute,        
contingent or otherwise) required by GAAP to be set forth on a consolidated     
balance sheet of Duke or in the notes thereto and which, individually or in the 
aggregate, would have a Duke Material Adverse Effect.                           

 (f) ABSENCE OF CERTAIN CHANGES OR EVENTS. Except as disclosed in the Duke
SEC Documents filed with the SEC prior to the date of this Agreement since      
December 31, 1997 (the "DUKE FINANCIAL STATEMENT DATE") and to the date of this 
Agreement, Duke and the Duke Subsidiaries have conducted their business only in 
the ordinary course and there has not been (i) any change that would have a Duke
Material Adverse Effect (a "DUKE MATERIAL ADVERSE CHANGE"), nor has there been  
any occurrence or circumstance that with the passage of time would reasonably be
expected to result in an Duke Material Adverse Change, (ii) any declaration,    
setting aside or payment of any dividend or distribution (whether in cash, stock
or property) with respect to any of Duke's capital stock or any Duke OP Units,  
except for (A) regular quarterly dividends (in the case of Duke) of $.34 per    
share of Duke Common Stock, and the dividend, if any, to be paid by Duke        
pursuant to Section 2.2(c)(i) (and the corresponding Duke OP distribution), (B) 
regular quarterly distributions (in the case of Duke OP) of $.34 per Duke Common
OP Unit, $.56875 per Duke Series A Preferred OP Unit, $.99875 per Duke Series B 
Preferred OP Unit, $.46 per Duke Series D Preferred Unit and $.515625 per Duke  
Series E Preferred Unit, (C) regularly quarterly dividends (in the case of Duke)
of $.56875 on outstanding shares of Duke Series A Preferred Stock, $.99875 on   
Duke Series B Preferred Stock, $.46 on Duke Series D Preferred Stock and        
$.515625 on Duke Series E Preferred Stock and (D) any distributions by any Duke 
Subsidiaries (other than Duke OP) to other Duke Subsidiaries or to Duke, in each
case with customary record and payment dates, (iii) any split, combination or   
reclassification of any of Duke's capital stock or any issuance or the          
authorization of any issuance of any other securities in respect of, in lieu of 
or in substitution for, or giving the right to acquire by exchange or exercise, 
shares of its capital stock or any issuance of an ownership interest in any Duke
Subsidiary, (iv) any damage, destruction or loss, whether or not covered by     
insurance, that has or would have a Duke Material Adverse Effect, or (v) any    
change in accounting methods, principles or practices by Duke or any Duke       
Subsidiary materially affecting its assets, liabilities or business, except     
insofar as may have been disclosed in the Duke SEC Documents filed with the SEC 
prior to the date of this Agreement, or required by a change in GAAP.

    (g) LITIGATION. Except as disclosed in the Duke SEC Documents filed with the
SEC prior to the date of this Agreement and other than personal injury and other
routine tort litigation arising from the ordinary course of operations of Duke  
or the Duke Subsidiaries which are covered by adequate insurance, there is no   
suit, action or proceeding pending or, to the knowledge of Duke and Duke OP,    
threatened against or affecting Duke or any Duke Subsidiary that, individually  
or in the aggregate, could reasonably be expected to (i) have a Duke Material   
Adverse Effect or (ii) prevent the consummation of any of the transactions      
contemplated hereby, nor is there any judgment, decree, injunction, rule or     
order of any Governmental Entity or arbitrator outstanding against Duke or any  
Duke Subsidiary having, or which, insofar as reasonably can be foreseen, in the 
future would have, any such effect.                                             

(h) ABSENCE OF CHANGES IN BENEFIT PLANS; ERISA COMPLIANCE.              

    (i) Except as disclosed in the Duke SEC Documents filed with the SEC
prior to the date of this Agreement, since the Duke Financial Statement 
   Date, there has not been any adoption or amendment in any material respect,
or the undertaking of any additional obligation, by Duke, any Duke      
Subsidiary or any Duke ERISA Affiliate (as defined below) of any Duke   
Benefit Plan (as defined below). For purposes of this Agreement, "DUKE  
   BENEFIT PLAN" shall mean any Employee Plan sponsored or maintained by Duke,
 any Duke Subsidiary or any Duke ERISA Affiliate, or with respect to which
   Duke, any Duke Subsidiary or any Duke ERISA Affiliate has any obligation to
contribute, has liability under or is otherwise a party to, or which    
  otherwise provides benefits for any current or former employees, officers,
directors or other independent contractors (or their dependents and     
beneficiaries) of Duke or any Duke Subsidiary. For purposes of this     
    Agreement, "DUKE ERISA AFFILIATE" means any entity required to be aggregated
  with any of Duke or any Duke Subsidiary under Sections 414(b), (c), (m) or
(o) of the Code or Section 4001 of ERISA. Schedule 3.2(h)(i) to the Duke
Disclosure Letter sets forth each Duke Benefit Plan.                    

     (ii) Except as described in the Duke SEC Documents filed with the SEC
prior to the date of this Agreement or as would not have a Duke Material
   Adverse Effect, (A) all Duke Benefit Plans, including any such plan that is
an "employee benefit plan" as defined in Section 3(3) of ERISA, are in  
 compliance with the terms of such plan and all applicable requirements of
   law, including ERISA and the Code and, without limitation, the requirements
 of ERISA and all tax rules for which favorable tax treatment is intended,
and (B) there are no liabilities or obligations with respect to any such
Duke Benefit Plan, whether accrued, contingent or otherwise (other than 
    obligations by Duke and the Duke Subsidiaries to make contributions, and for
    such plan to pay benefits and administrative costs, incurred in the ordinary
course), nor to the knowledge of Duke are any such liabilities or       
 obligations expected to be incurred. The execution of, and performance of
  the transactions contemplated in, this Agreement will not (either alone or
together with the occurrence of any additional or subsequent events)    
constitute an event under any Duke Benefit Plan, policy, program,       
arrangement or agreement, trust or loan that will or may result in any  
  payment (whether of severance pay or otherwise), acceleration, forgiveness
  of indebtedness, vesting, distribution, increase in benefits or obligation
  to fund benefits with respect to any employee or director, will not result
in any "golden parachute payments" being due (as defined for purposes of
Section 280G of the Code), or result in any breach or violation of, or a
   default under, any of the Duke Benefit Plans. The only severance agreements
 or severance policies applicable to Duke or the Duke Subsidiaries are the
 agreements and policies specifically referred to in Section 3.2(h)(ii) of
the Duke Disclosure Letter.                                             

     (iii) Without limiting the foregoing, each Duke Benefit Plan which is
intended to be tax-qualified under Section 401(a) of the Code has been  
    determined by the IRS to be so qualified and such determination has not been
   modified, revoked or limited, and no circumstances have occurred that would
   adversely affect the tax-qualified status of any such plan. No Duke Benefit
Plan is or has ever been subject to Part III of Subtitle B of Title I of
  ERISA or Title IV of ERISA or Section 412 of the Code. None of Duke or any
   Duke Subsidiary, or any "party in interest" (as defined in Section 3(14) of
    ERISA) or any "disqualified person" (as defined in Section 4975 of the Code)
with respect to any Duke Benefit Plan, has engaged in a non-exempt      
  "prohibited transaction" within the meaning of Section 4975 of the Code or
Section 406 of ERISA that would have a Duke Material Adverse Effect.

(i) TAXES.                                                              

        (i) Each of Duke and each Duke Subsidiary (including Duke OP) has timely
filed with the appropriate taxing authority all Tax Returns and reports 
required to be filed by it (after giving effect to any filing extension 
  properly granted by a Governmental Entity having authority to do so). Each
    such Tax Return is true, correct and complete in all material respects. Duke
   and each Duke Subsidiary (including Duke OP) have paid (or Duke has paid on
   their behalf), within the time and manner prescribed by law, all Taxes that
  are due and payable. The Tax Returns of Duke and each Duke Subsidiary have
 not been audited by any Taxing Authority. There are no Tax liens upon the
assets of Duke or any Duke Subsidiary other than liens for Taxes not yet
due. The most recent financial statements contained in the Duke SEC     
   Documents filed with the SEC prior to the date of this Agreement reflect an
adequate reserve for all material Taxes payable by Duke and by each Duke
   Subsidiary for all taxable periods and portions thereof through the date of
    such financial statements. Since the Duke Financial Statement Date, Duke has
incurred no liability for federal taxes, other than withholding and     
 employment taxes, under the Code or IRS Notice 88-19. To the knowledge of
   Duke, no event has occurred, and no condition or circumstance exists, which
 presents a material risk that any material Tax described in the preceding
sentence will be imposed upon Duke. To the knowledge of Duke, no        
   deficiencies for any Taxes have been proposed, asserted or assessed against
Duke or any of the Duke Subsidiaries, and no requests for waivers of the
time to assess any such Taxes have been granted or are pending.         

     (ii) Duke (A) for all of its taxable years beginning with its taxable
year ending on December 31, 1986 has been subject to taxation as a REIT 
    within the meaning of the Code and has satisfied the requirements to qualify
as a REIT for such years, (B) has operated, and intends to continue to  
   operate, in such a manner as to qualify as a REIT, and (C) has not taken or
    omitted to take any action which could reasonably be expected to result in a
challenge to its status as a REIT, and, to Duke's knowledge, no such    
    challenge is pending or threatened. Duke OP has at all times, and each other
    Duke Subsidiary which is a partnership or limited liability company or files
  Tax Returns as a partnership for federal income tax purposes has since its
 acquisition by Duke, been classified for federal income tax purposes as a
partnership or disregarded entity and not as an association taxable as a
    corporation or a "publicly traded partnership" within the meaning of Section
   7704(b) of the Code that is treated as a corporation for federal income tax
  purposes under Section 7704(a) of the Code. Duke OP has operated, and Duke
intends to cause Duke OP to continue to operate, in such a manner as to 
   satisfy the gross income requirements of Section 7704(c)(2) of the Code, so
 that if Duke OP were classified as a publicly traded partnership, Duke OP
   would not be treated for federal income tax purposes as a corporation under
Section 7704(a) of the Code.                                            

   (iii) To the best knowledge and belief of Duke, Duke qualifies as a
    "domestically-controlled" REIT within the meaning of Section 897(h)(4)(B) of
the Code, as of the date hereof.                                        

(j) NO LOANS OR PAYMENTS TO EMPLOYEES, OFFICERS OR DIRECTORS. Except as 
disclosed in the Duke SEC Documents or as otherwise specifically provided for in
this Agreement, there is no (i) loan outstanding from or to any employee or     
director, (ii) employment or consulting contracts, (iii) agreements requiring   
payments to be made on a change of control or otherwise as a result of the      
consummation of any of the transactions with respect to any employee, officer or
director of Duke or any Duke Subsidiary or (iv) any agreement to appoint or     
nominate any person as a director of Duke.                                      

 (k) BROKERS; SCHEDULE OF FEES AND EXPENSES. No broker, investment banker,
financial advisor or other person, other than Merrill Lynch & Co., the fees and 
expenses of which, as set forth in a letter agreement between Duke and such     
financial advisor, have previously been disclosed to Weeks and will be paid by  
Duke, is entitled to any broker's, finder's, financial advisor's or other       
similar fee or commission in connection with the REIT Merger, the OP Merger or  
any of the transactions contemplated by this

Agreement or the OP Merger Agreement based upon arrangements made by or on      
behalf of Duke or any other Duke Subsidiary.                                    

(l) COMPLIANCE WITH LAWS. Except as disclosed in the Duke SEC Documents 
filed with the SEC prior to the date of this Agreement neither Duke nor any of  
the Duke Subsidiaries has violated or failed to comply with any statute, law,   
ordinance, regulation, rule, judgment, decree or order of any Governmental      
Entity applicable to its business, properties or operations, except for         
violations and failures to comply that would not, individually or in the        
aggregate, reasonably be expected to result in a Duke Material Adverse Effect.  

(m) CONTRACTS; DEBT INSTRUMENTS.                                        

    (i) Neither Duke nor any Duke Subsidiary has received written notice
    that it is in violation of or in default under, in any material respect (nor
   does there exist any condition which upon the passage of time or the giving
of notice or both would cause such a violation of or default under), any
  material loan or credit agreement, note, bond, mortgage, indenture, lease,
  permit, concession, franchise or license, or any agreement to acquire real
property, or any other material contract, agreement, arrangement or     
understanding, to which it is a party or by which it or any of its      
   properties or assets is bound, except for violations or defaults that would
not, individually or in the aggregate, result in a Duke Material Adverse
Effect.                                                                 

      (ii) Section 3.2(m)(ii) of the Duke Disclosure Letter sets forth (A) a
detailed list of all loan indebtedness of Duke or any of the Duke       
    Subsidiaries, other than indebtedness payable to Duke or a wholly owned Duke
Subsidiary, in an aggregate principal amount in excess of $5,000,000 per
item is outstanding or may be incurred and (B) the respective principal 
amounts outstanding thereunder on December 31, 1998.                    

 (iii) Neither Duke nor any Duke Subsidiary has entered into or is
  subject, directly or indirectly, to any Duke Tax Protection Agreements. As
used herein, a "DUKE TAX PROTECTION AGREEMENT" is an agreement, oral or 
   written, (A) that has as one of its purposes to permit a Person to take the
   position that such Person could defer federal taxable income that otherwise
  might have been recognized attributable to the acquisition or ownership of
    Duke OP Units or an interest in any other Duke Subsidiary that is treated as
    a partnership for federal income tax purposes, and (B) that (i) prohibits or
 restricts in any manner the disposition of any assets of Duke or any Duke
Subsidiary, (ii) requires that Duke or any Duke Subsidiary maintain,    
  increase or put in place, or replace, indebtedness, whether or not secured
 by one or more of the Duke Properties, or (iii) requires that Duke or any
    Duke Subsidiary offer to any person or entity at any time the opportunity to
   guarantee or otherwise assume, directly or indirectly, the risk of loss for
    federal income tax purposes for indebtedness or other liabilities of Colt or
any Colt Subsidiary.                                                    

(n) DUKE OP AGREEMENT. The Duke OP Agreement has been duly authorized,  
executed and delivered by Duke. Assuming due execution by the limited partners  
of Duke OP, the Duke OP Agreement constitutes a valid and binding obligation of 
Duke, enforceable against Duke in accordance with its terms.                    

    (o) ENVIRONMENTAL MATTERS. Except as disclosed in Section 3.2(o) of the Duke
Disclosure Letter, each of Duke and each Duke Subsidiary has obtained all       
licenses, permits, authorizations, approvals and consents from Governmental     
Entities which are required of Duke and each Duke Subsidiary in respect of its  
business, operations, assets or properties under any applicable Environmental   
Law, and each of Duke and each Duke Subsidiary is in compliance in all respects 
with the terms and conditions of all such licenses, permits, authorizations,    
approvals and consents and with its obligations under any applicable            
Environmental Law, except for such failures to comply which would not,          
individually or in the aggregate, have a Duke

   (a)  As soon as practicable following the date of this Agreement, Weeks and
Duke shall (i) prepare and file with the SEC a preliminary joint Proxy          
Statement, with appropriate requests for confidential treatment, in form and    
substance satisfactory to each of Duke and Weeks, and Duke will provide on a    
supplemental basis to the SEC the Registration Statement, in which the Proxy    
Statement will be included as a prospectus. Each of Weeks and Duke shall use its
commercially reasonable efforts to cause and enable Duke to (i) respond to any  
comments of the staff of the SEC and (ii) have the Registration Statement       
declared effective under the Securities Act and the rules and regulations       
promulgated thereunder as promptly as practicable after such filing and to keep 
the Registration Statement effective as long as is necessary to consummate the  
REIT Merger. Each of Weeks and Duke will use its commercially reasonable efforts
to cause the Proxy Statement to be mailed to Weeks' shareholders and Duke's     
shareholders, respectively, as promptly as practicable after the Registration   
Statement is declared effective under the Securities Act. Each party will notify
the other promptly of the receipt of any comments from the SEC and of any       
request by the SEC for amendments or supplements to the Registration Statement  
or the Proxy Statement or for additional information and will supply the other  
with copies of all correspondence between such party or any of its              
representatives and the SEC with respect to the Registration Statement or the   
Proxy Statement. The Registration Statement and the Proxy Statement shall comply
in all material respects with all applicable requirements of Law. Whenever any  
event occurs which is required to be set forth in an amendment or supplement to 
the Registration Statement or the Proxy Statement, Duke or Weeks, as the case   
may be, shall promptly inform the other of such occurrences and cooperate in    
filing with the SEC and/or mailing to the shareholders of Duke and the          
shareholders of Weeks such amendment or supplement in a form reasonably         
acceptable to Duke and Weeks.                                                   

(b)  Weeks will, as soon as practicable following the date of this      
Agreement, duly call, give notice of, convene and hold a meeting of its         
shareholders (the "WEEKS SHAREHOLDERS MEETING") (but in no event shall such     
meeting be held sooner than 20 business days following the date the Proxy       
Statement is mailed to its shareholders), for the purpose of obtaining the Weeks
Shareholder Approvals. Duke will, as soon as practicable following the date of

Statement is mailed to its shareholders), for the purpose of obtaining the Duke 
Shareholder Approvals. Weeks and Duke will cooperate in good faith to seek to   
ensure that the Weeks Shareholder Meeting and the Duke Shareholder Meeting are  
held on the same day, as close together in time as is reasonably practicable.   
Duke covenants that, subject to Section 7.1, Duke will, through its Board of    
Directors, recommend to its shareholders approval of the REIT Merger, the OP    
Merger, this Agreement, the OP Merger Agreement, the charter and bylaw          
amendments, the election of directors and the other transactions contemplated   
hereby and thereby and further covenants that the Proxy Statement will include  
such recommendation. Weeks covenants that, subject to Section 7.1, Weeks will,  
through its Board of Directors, recommend to its shareholders approval of the   
REIT Merger, the OP Merger, this Agreement, the OP Merger Agreement and the     
other transactions contemplated hereby and thereby and further covenants that   
the Proxy Statement will include such recommendation. Duke shall furnish all    
information concerning Duke and the holders of Duke Common Stock as may         
reasonably be requested in connection with any action required to be taken under
any applicable state securities or "blue sky" laws in connection with the       
issuance of Duke Common Stock pursuant to the REIT Merger, and Weeks shall      
furnish all information concerning Weeks and the holders of Weeks Stock as may  
be reasonably requested in connection with any such action. Each of Duke and    
Weeks will use their commercially reasonable efforts to cause Duke to obtain,   
prior to the effective date of the Registration Statement, all necessary state  
securities or "blue sky" permits or approvals required to carry out the REIT

respective subsidiaries to, furnish promptly to the other party (a) a copy of   
each report, schedule, registration statement and other document filed by it    
during such period pursuant to the requirements of federal or state securities  
laws and (b) all other information concerning its business, properties and      
personnel as such other party may reasonably request. Each of Weeks and Duke    
will hold, and will cause its respective subsidiaries' officers, employees,     
accountants, counsel, financial advisors and other representatives and          
affiliates to hold, any nonpublic information in confidence to the extent

shall consult reasonably with the other party upon reasonable notice prior to   
making payment of any such amount, and in no event shall either Weeks or Duke

Merger to qualify as a tax-deferred exchange for Weeks and the other holders of 
Weeks OP Units, and (c) obtain the opinions of counsel referred to in Sections

Section 5.11.  BENEFIT PLANS AND OTHER EMPLOYEE ARRANGEMENTS.           

(a)  BENEFIT PLANS. Subject to subsection (b) below, upon and after the 
Effective Time, Duke and Duke OP (or their respective successors or assigns)    
shall provide benefits to former employees of Weeks and its Subsidiaries that   
are no less favorable in the aggregate to such employees than those provided to 
other similarly situated employees of Duke and Duke OP at any applicable time   
after the termination of the benefits provided to such employees by Weeks and   
the Weeks Subsidiaries. With respect to any Duke Benefit Plan which is an       
"employee benefit plan" as defined in Section 3(3) of ERISA and any other       
service based benefits (including vacations) in which employees of Weeks or Duke
or their respective Subsidiaries may participate, solely for purposes of        
determining eligibility to participate, vesting and entitlement to benefits but 
not for purposes of accrual of pension benefits, service with Weeks, Duke or any
of their respective Subsidiaries shall be treated as service with Duke or Duke  
OP, as the case may be; PROVIDED, HOWEVER, that such service shall not be       
recognized to the extent that such recognition would result in a duplication of 
benefits under both a Weeks Benefit Plan and a Duke Benefit Plan (or is not     
otherwise recognized for such purposes under the benefit plans of Duke or Duke  
OP).                                                                            

(b)  STOCK INCENTIVE PLANS.                                             

        (i)  As of the Effective Time, each outstanding Weeks Stock Option shall
  be assumed by Duke and shall be deemed to constitute an option to acquire,
  on the same terms and conditions as were applicable under such Weeks Stock
Option (including, without limitation, vesting and exercisability but   
 without regard to any provisions that would result in the acceleration of
such vesting or exercisability due to the execution and delivery of this
Agreement or the consummation of the transactions contemplated by this  
   Agreement), the same number of shares of Duke Common Stock as the holder of
   such Weeks Stock Option would have been entitled to receive pursuant to the
REIT Merger had such holder exercised such Weeks Stock Option in full   
immediately prior to the Effective                                      
Time at a price per share equal to the aggregate exercise price for the 
shares subject to such Weeks Stock Option divided by the number of full 
   shares of Duke Common Stock deemed to be purchasable pursuant to such Weeks
 Stock Option; PROVIDED, HOWEVER, that the number of shares of Duke Common
  Stock that may be purchased upon exercise of such Weeks Stock Option shall
not include any fractional share but shall be rounded upward to the next
  whole number of shares, or if rounding up would disqualify an option as an
 incentive stock option, shall be rounded down to the nearest whole number
 and cash shall be paid to each affected optionee as compensation for such
   fractional share based on the fair market value of Duke Common Stock at the
  Effective Time. Shares of Duke Common Stock received pursuant to the terms
  of this Agreement, in consideration for shares of Weeks Common Stock which
have been held by Weeks executives and which are unvested and subject to
   forfeiture at the Effective Time pursuant to a restricted stock award under
a Weeks Stock Plan shall vest and be subject to forfeiture in accordance
with the terms of the applicable restricted stock award of Weeks Common 
Stock in the absence of the transactions contemplated by this Agreement.
Prior to the Effective Time, Weeks will use its commercially reasonable 
   efforts to obtain any necessary consents and shall (to the extent permitted
 under the terms of the Weeks Stock Plans) make any amendments to and take
any actions in respect of any Weeks Stock Plans, Weeks Stock Options or 
restricted stock award to the extent such consents or amendments are    
    necessary to give effect to the foregoing (including without limitation, the
  elimination of any right to acceleration of exercisability or vesting as a
result of the completion of the transactions contemplated by this       
Agreement).                                                             

       (ii)  Each Duke Stock Option shall continue in accordance with its term
 and conditions, including, without limitation, vesting and exercisability
  without regard to any acceleration of such vesting and exercisability as a
result of the transactions contemplated by this Agreement. Prior to the 
Effective Time, Duke will use its best efforts to obtain any necessary  
    consents and make any amendments to any Duke Stock Plans or Duke Weeks Stock
Options to the extent such consents or amendments are necessary to give 
effect to the foregoing.

     (iii)  At the Effective Time, Duke shall assume the Weeks Stock Plans
(such Weeks Stock Plans having been amended as appropriate to take into 
account the adjustments set forth in Section 5.11(b)(i)), and the       
 compensation committee of the Board of Directors of Duke shall administer
    the Weeks Stock Plans. At the Effective Time, the Weeks Stock Plans shall be
amended such that no further options shall be issued thereunder.        

    (c)  CHANGE IN CONTROL AGREEMENTS. At the Effective Time, Weeks shall assign
and Duke shall assume by operation of this Agreement Weeks' obligations under   
Weeks' Change in Control Agreements identified in Section 5.11(c) of the Weeks  
Disclosure Letter.                                                              

Section 5.12.  INDEMNIFICATION; DIRECTORS' AND OFFICERS' INSURANCE.     

   (a) (i)  Weeks shall, and, from and after the Effective Time, the Surviving
Corporation and the Surviving Partnership (collectively, the "INDEMNIFYING      
PARTIES") shall, indemnify, defend and hold harmless each person who is now or  
has been at any time prior to the date hereof or who becomes prior to the       
Effective Time, an officer or director of Weeks or any Weeks Subsidiary (the    
"Indemnified Parties") against all losses, claims, damages, costs, expenses     
(including attorneys' fees and expenses), liabilities or judgments or amounts   
that are paid in settlement of, with the approval of the Indemnifying Parties   
(which approval shall not be unreasonably withheld or delayed), or otherwise in 
connection with any threatened or actual claim, action, suit, proceeding or     
investigation based on or arising out of the fact that such person is or was a  
director or officer of Weeks or any Weeks Subsidiary at or prior to the         
Effective Time, whether asserted or claimed prior to, or at or after, the       
Effective Time ("INDEMNIFIED LIABILITIES"), including all Indemnified           
Liabilities based on, or arising out of, or pertaining to this Agreement, the   
REIT Merger, the OP Merger or the transactions contemplated by this Agreement or
the OP Merger Agreement, in each case to the full extent a corporation is       
permitted under the GBCC to indemnify its own directors or officers, as the case
may be (and the Surviving Corporation will pay expenses in advance of the final 
disposition of any such action or proceeding to each Indemnified Party to the   
full extent permitted by law subject to the limitations set forth in Section    
5.12(a)(iii)).                                                                  

 (ii)  Any Indemnified Parties proposing to assert the right to be
   indemnified under this Section 5.12 shall, promptly after receipt of notice
    of commencement of any action against such Indemnified Parties in respect of
   which a claim is to be made under this Section 5.12 against Weeks and, from
and after the Effective Time, the Surviving Corporation, notify the     
    Indemnifying Parties of the commencement of such action, enclosing a copy of
all papers served. If any such action is brought against any of the     
Indemnified Parties and such Indemnified Parties notify the Indemnifying
 Parties of its commencement, the Indemnifying Parties will be entitled to
participate in and, to the extent that they elect by delivering written 
 notice to such Indemnified Parties promptly after receiving notice of the
commencement of the action from the Indemnified Parties, to assume the  
   defense of the action and after notice from the Indemnifying Parties to the
Indemnified Parties of their election to assume the defense, the        
  Indemnifying Parties will not be liable to the Indemnified Parties for any
legal or other expenses except as provided below and except for the     
  reasonable costs of investigation subsequently incurred by the Indemnified
  Parties in connection with the defense. If the Indemnifying Parties assume
 the defense, the Indemnifying Parties shall have the right to settle such
 action without the consent of the Indemnified Parties; PROVIDED, HOWEVER,
that the Indemnifying Parties shall be required to obtain such consent  
(which consent shall not be unreasonably withheld) if the settlement    
   includes any admission of wrongdoing on the part of the Indemnified Parties
    or any decree or restriction on the Indemnified Parties or their officers or
  directors; PROVIDED, FURTHER, that no Indemnifying Parties, in the defense
    of any such action shall, except with the consent of the Indemnified Parties
   (which consent shall not be unreasonably withheld), consent to entry of any
judgment or enter into any settlement that does not include as an       
  unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Parties of a release from all liability with respect to such
action. The Indemnified Parties will have the right to employ their own 
    counsel in any such action, but the fees, expenses and other charges of such
counsel will be at the expense of such Indemnified Parties unless

    (i) the employment of counsel by the Indemnified Parties has been authorized
 in writing by the Indemnifying Parties, (ii) the Indemnified Parties have
 reasonably concluded (based on advice of counsel) that there may be legal
  defenses available to them that are different from or in addition to those
available to the Indemnifying Parties, (iii) a conflict or potential    
conflict exists (based on advice of counsel to the Indemnified Parties) 
   between the Indemnified Parties and the Indemnifying Parties (in which case

  such action on behalf of the Indemnified Parties) or (iv) the Indemnifying
Parties have not in fact employed counsel to assume the defense of such 
  action within a reasonable time after receiving notice of the commencement
    of the action, in each of which cases the reasonable fees, disbursements and
    other charges of counsel will be at the expense of the Indemnifying Parties.

   (iii)  It is understood that the Indemnifying Parties shall not, in
connection with any proceeding or related proceedings in the same       
jurisdiction, be liable for the reasonable fees, disbursements and other
charges of more than one separate firm admitted to practice in such     
    jurisdiction at any one time for all such Indemnified Parties unless (a) the
 employment of more than one counsel has been authorized in writing by the
Indemnifying Parties, (b) any of the Indemnified Parties have reasonably
concluded (based on advice of counsel) that there may be legal defenses 
   available to them that are different from or in addition to those available
   to other Indemnified Parties or (c) a conflict or potential conflict exists
  (based on advice of counsel to the Indemnified Parties) between any of the
    Indemnified Parties and the other Indemnified Parties, in each case of which
  the Indemnifying Parties shall be obligated to pay the reasonable fees and
expenses of such additional counsel or counsels.                        

       (iv)  The Indemnifying Parties will not be liable for any settlement of
 any action or claim effected without their written consent (which consent

  (c)  At or prior to the Effective Time, Duke shall purchase directors' and
officers' liability insurance "tail" policy coverage for Weeks' directors and   
executive officers for a period of six years which will provide the directors   
and officers with coverage on substantially similar terms as currently provided 
by Weeks to such directors and officers for claims based on activity prior to   
the Effective Time; provided, however, that Duke shall have no obligation to pay
more than $250,000 in premiums for such coverage.                               

   (d)  The provisions of this Section 5.12 are intended to be for the benefit

Section 5.13.  PROVISIONS RELATING TO CERTAIN WEEKS

Duke shall utilize reasonable best efforts and cooperate with each other to     
cause the condition specified in Section 6.2(f) and 6.3(f) to be satisfied on or
prior to the Closing Date.                                                      

Section 5.14.  THE WEEKS RIGHTS PLAN.  Weeks shall either (i) redeem,   
effective immediately prior to the Effective Time, all the then outstanding     
Rights (as defined in the Rights Agreement) for cash pursuant to and in         
compliance with Section 23 of the Rights Agreement or (ii) take such other      
action to terminate the Rights Agreement as of that time, as Weeks and Duke may 
mutually agree. Weeks shall not redeem the Rights issued under the Rights       
Agreement, or terminate the Rights Agreement, prior to the Effective Time (other
than in accordance with the preceding sentence) unless required to do so by a   
court of competent jurisdiction; provided, however, that Weeks may take any of  
the foregoing actions if the Board of Directors of Weeks shall have accepted a  
proposal for a Superior Competing Transaction in accordance with the terms of   
Section 7.1.

Common Stock and the record dates and payment dates relating thereto, it being  
the intention of Duke and Weeks that any holder of Weeks Common Stock shall not 
receive two dividends, or fail to receive one dividend, for any single calendar 
quarter with respect to such holder's Weeks Common Stock and/or Duke Common     
Stock such holder receives in exchange therefor pursuant to the REIT Merger.    
Each of Duke OP and Weeks OP shall coordinate with the other regarding the      
declaration and payment of distributions in respect of Duke common OP units and 
Weeks common OP units and the record dates and payment dates relating thereto,  
it being the intention of Duke OP and Weeks OP that any holder of Weeks common  
OP units shall not receive two distributions, or fail to receive one            
distribution, for any single calendar quarter with respect to such holder's     
Weeks OP common units and/or Duke common OP Units any such holder receives in

shall remain outstanding following the Effective Time. At the Effective time,   
the AEW Warrant Agreement and each outstanding AEW Warrant and the Codina       
Warrant Agreement and each outstanding Codina Warrant shall be assumed by the   
Surviving Entity. Each such Warrant shall be deemed to constitute a warrant to  
acquire, on the same terms and conditions as were applicable under such Warrant,
a number of shares of Duke Common Stock equal to the number of shares of Duke   
Common Stock purchasable pursuant to such Warrant multiplied by the Exchange    
Ratio (plus the amount of cash consideration, if any, payable with respect to   
the number of shares of Duke Common Stock issuable upon the exercise of such    
Warrant immediately prior to the Effective Time), at a price per share equal to 
the per-share exercise price for the shares of Weeks Common Stock purchasable   
pursuant to such Warrant divided by the Exchange Ratio. Any fractional interests
shall be rounded up to one share of Duke Common Stock (with all fractional      
interests to which a holder would otherwise be entitled being aggregated before 
any such rounding). Duke shall take all action necessary to reserve for issuance
a sufficient number of shares of Duke Common Stock for delivery upon exercise of
the Warrants assumed in accordance with this Section 5.17.

each covenant and agreement of the Indenture dated March 20, 1997 and a         
Supplemental Indenture dated July 30, 1998 between Weeks OP and State Street    
Bank and Company, as Trustee, and (b) cause to be delivered to the trustee an   
opinion of counsel to the effect that all agreements or instruments effecting   
such assumption are enforceable in accordance with their terms and comply with  
the terms of such Indenture.                                                    

    Section 5.19.  DUKE OP PARTNERSHIP AGREEMENT.  At the Closing, Duke OP shall
(i) amend the partnership agreement of Duke OP to reflect the agreements        
described on Exhibit J hereto and (ii) assume and perform any obligations that  
Weeks OP or any Weeks Subsidiary has immediately prior to the Effective Time to 
issue securities in accordance with the terms of any partnership or other       
agreement to which Weeks OP or such Subsidiary is a party and which has been    
previously disclosed to Duke, in the same manner and to the same extent that    
Weeks OP or such Subsidiary would be required to perform such obligation if no  
Merger had been consummated.

Board of Directors of Duke shall take such action as may be necessary or        
advisable to ensure the appointment of the persons named on Schedule G hereto as

in connection with a Superior Competing Transaction, provided that it shall have
notified either Duke or Weeks, as the case may be, of such unsolicited requests 
or its participation in discussions or negotiations in accordance with Section

its approval or recommendation of this Agreement, the OP Merger Agreement and   
the REIT Merger and the OP Merger) a Superior Competing Transaction (as defined

which a majority of the members of the Board of Directors of Duke or Weeks, as

(k)  by Weeks if (i) prior to the Duke Shareholders Meeting the Board of
Directors of Duke or any committee thereof shall have withdrawn or modified in

Section 8.2.  EXPENSES.                                                 

   (a)  Except as otherwise specified in this Section 8.2 or agreed in writing
by the parties, all out-of-pocket costs and expenses incurred in connection with
this Agreement, the REIT Merger, the OP Merger Agreement, the OP Merger and the 
other transactions contemplated hereby and the OP Merger Agreement shall be paid
by the party incurring such cost or expense.                                    

(b)  Weeks agrees that if this Agreement shall be terminated pursuant to
Section 8.1(b) then Weeks will pay to Duke, or as directed by Duke, an amount   
equal to the Duke Break-Up Expenses (as defined below). In addition, Weeks      
agrees that if (x) this Agreement shall be terminated pursuant to Section 8.1(b)
or (f) and within 12 months following such termination Weeks or Weeks OP shall  
consummate a Competing Transaction or enter into a definitive agreement         
providing for a Competing Transaction or (y) this Agreement is terminated       
pursuant to Section 8.1(h) or (j), then Weeks will pay as directed by Duke a fee
in an amount equal to the Duke Break-Up Fee (as defined below) less any Duke    
Break-Up Expenses. Payment of any of such amounts shall be made, as directed by 
Duke, by wire transfer of immediately available funds promptly, but in no event 
later than two business days after the amount is due as provided herein. The    
"DUKE BREAK-UP FEE" shall be an amount equal to the lesser of (i) $50,000,000   
(the "BASE AMOUNT") or (ii) the sum of (A) the maximum amount that can be paid  
to Duke or Duke OP for the taxable year in which this Agreement is terminated   
without causing Duke 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  
income described in Sections 856(c)(2) and (3) of the Code ("QUALIFYING         
INCOME"), as determined by outside counsel or independent accountants to Duke,  
and (B) in the event Duke receives a letter from outside counsel (the "DUKE     
BREAK-UP FEE TAX OPINION") indicating that Duke has received a ruling from the  
IRS holding that the receipt by Duke or Duke OP of the Base Amount would either 
constitute Qualifying Income as to Duke with respect to Duke's proportionate    
share thereof or would be excluded from Duke's gross income for purposes of     
Sections 856(c)(2) and (3) of the Code (the "REIT REQUIREMENTS"), the Base      
Amount less the amount payable under clause (A) above. In the event that Duke OP
is not able to receive the full Base Amount, Weeks shall place the unpaid amount
in escrow and shall not release any portion thereof to Duke or Duke OP unless   
and until Weeks receives any one or a combination of the following: (i) a       
letter(s) from Duke's outside counsel or independent accountants indicating the 
maximum amount that can be paid at that time to Duke OP without causing Duke to 
fail to meet the REIT Requirements for any relevant taxable year, together with 
an IRS ruling or opinion of the counsel to the effect that such payment would   
not be treated as included in the income of Weeks for any prior taxable year, in
which event such maximum amount shall be paid to Duke OP, or (ii) a Duke        
Break-Up Fee Tax Opinion, in which event Weeks shall pay to Duke OP the unpaid  
Base Amount. Weeks' obligation to pay any unpaid portion of the Duke Break-Up   
Fee (provided Weeks has otherwise complied with its obligations under this      
provision) shall terminate (and any amount still held in such escrow shall be   
released to Weeks) on the date that is five years from the date the Duke        
Break-Up Fee first becomes due under this Agreement. The "DUKE BREAK-UP         
EXPENSES" shall be an amount equal to the lesser of (i) Duke OP's out-of-pocket 
expenses incurred in connection with this Agreement and the other transactions  
(including, without limitation, all attorneys', accountants' and investment     
bankers' fees and expenses) but in no event in an amount greater than $5,000,000
(such amount not to exceed such $5,000,000 being referred to in this Section    
8.2(b) or (c) as the "DUKE EXPENSE FEE BASE AMOUNT") and (ii) the sum of (A) the
maximum amount that can be paid to Duke OP without causing Duke 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, as determined by outside counsel or independent accountants to Duke and 
(B) in the event Duke receives a Duke Break-Up Fee Tax Opinion indicating that  
Duke has received a ruling from the IRS holding that Duke OP's receipt of the   
Duke Expense Fee Base Amount would either constitute Qualifying Income as to    
Duke with respect to Duke's proportionate share thereof or would be excluded    
from Duke's gross income for purposes of the REIT Requirements, the Duke Expense
Fee Base Amount less the amount payable under clause (A) above. In the event    
that Duke is not able to receive the full amount of the Duke Break-Up Expenses, 
Weeks shall place the unpaid amount in escrow and shall not release any portion 
thereof to Duke OP unless and until Weeks receives any one or combination of the
following: (i) a letter(s) from Duke's outside counsel or independent           
accountants indicating the maximum amount that can be paid at that time to Duke 
OP without causing Duke to fail to meet the REIT Requirements for any relevant  
taxable year together with an IRS ruling or opinion of tax counsel to the effect
that such payment would not be treated as included in income for any prior      
taxable year, in which event such maximum amount shall be paid to Duke OP, or   
(ii) a Duke Break-Up Fee Tax Opinion indicating that Duke's receipt of the      
Expense Fee Base Amount would satisfy in whole or in part the REIT Requirements,
in which event Weeks shall pay to Duke OP the unpaid Duke Expense Fee Base      
Amount. Weeks' obligation to pay any unpaid portion of the Duke Break-Up        
Expenses (provided Weeks has otherwise complied with its obligations under this 
provision) shall terminate (and any amount still held in such escrow shall be   
released to Weeks) on the date that is five years from the date the Duke        
Break-Up Expenses first become due under this Agreement.                        

(c)  Duke agrees that if this Agreement shall be terminated pursuant to 
Section 8.1(c), then Duke will pay, as directed by Weeks, an amount equal to the
Weeks Break-Up Expenses (as defined below). In addition, Duke and Duke OP agree 
that if (x) this Agreement shall be terminated pursuant to Section 8.1(c) or (g)
and within 12 months following such termination Duke or Duke OP shall consummate
a Competing Transaction or enter into a definitive agreement providing for a    
Competing Transaction or (y) this Agreement is terminated pursuant to Section   
8.1(i) or (k), then Duke or Duke OP will pay as directed by Weeks a fee in an   
amount equal to the Weeks Break-Up Fee (as defined below) less any Weeks        
Break-Up Expenses. Payment of any of such amounts shall be made, as directed by 
Weeks, by wire transfer of immediately available funds promptly, but in no event
later than two business days after the amount is due as provided herein. The    
"WEEKS BREAK-UP FEE" shall be an amount equal to the lesser of (i) $50,000,000  
(the "BASE AMOUNT") and (ii) the sum of (A) the maximum amount that can be paid 
to Weeks without causing it 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, as determined by independent accountants to   
Weeks and (B) in the event Weeks receives a letter from outside counsel (the    
"WEEKS BREAK-UP FEE TAX OPINION") indicating that Weeks has received a ruling   
from the IRS holding that Weeks' receipt of the Base Amount would either        
constitute Qualifying Income or would be excluded from gross income for purposes
of Sections 856(c)(2) and (3) of the Code, the Base Amount less the amount      
payable under clause (A) above. In the event that Weeks is not able to receive  
the full Base Amount, Duke shall place the unpaid amount in escrow and shall not
release any portion thereof to Weeks unless and until Duke receives any one or a
combination of the following: (i) a letter(s) from Weeks' outside counsel or    
independent accountants indicating the maximum amount that can be paid at that  
time to Weeks without causing Weeks to fail to meet the REIT Requirements for   
any relevant taxable year together with an IRS ruling or opinion of tax counsel 
to the effect that such payment would not be treated as included in income for  
any prior taxable year, in which even such maximum amount shall be paid to Weeks
OP, or (ii) a Weeks Break-Up Fee Tax Opinion, in which event Duke shall pay to  
Weeks the unpaid Base Amount. Duke's obligation to pay the Weeks Break-Up Fee   
(provided Duke has otherwise complied with its obligations under this provision)
shall terminate (and any amount still held in such escrow shall be released to  
Duke) on the date that is five years from the date the Weeks Break-Up Fee first 
becomes due under this Agreement. The "WEEKS BREAK-UP EXPENSES" shall be an     
amount equal to the lesser of (i) Weeks' out-of-pocket expenses incurred in     
connection with this Agreement and the other transactions (including, without   
limitation, all attorneys', accountants' and investment bankers' fees and       
expenses) but in no event

AMOUNT") and (ii) the sum of (A) the maximum amount that can be paid to Weeks   
without causing it 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, as determined by independent accountants to Weeks and (B) in 
the event Weeks receives a Weeks Break-Up Fee Tax Opinion indicating that Weeks 
has received a ruling from the IRS holding that Weeks' receipt of the Weeks     
Expense Fee Base Amount would either constitute Qualifying Income or would be   
excluded from gross income for purposes of the REIT Requirements or that receipt
by Weeks of the remaining balance of the Weeks Expense Fee Base Amount following
the receipt of and pursuant to such ruling would not be deemed constructively   
received prior thereto, the Expense Fee Base Amount less the amount payable     
under clause (A) above. In the event that Weeks is not able to receive the full 
Weeks Expense Fee Base Amount, Duke and Duke OP shall place the unpaid amount in
escrow and shall not release any portion thereof to Weeks OP unless and until   
Duke receives any one or combination of the following: (i) a letter(s) from     
Weeks' outside counsel or independent accountants indicating the maximum amount 
that can be paid at that time to Weeks OP without causing Weeks to fail to meet 
the REIT Requirements for any relevant taxable year together with an IRS ruling 
or opinion of tax counsel to the effect that such payment would not be treated  
as included in income for any prior taxable year, in which event such maximum   
amount shall be paid to Weeks OP, or (ii) a Weeks Break-Up Fee Tax Opinion      
indicating that Weeks' receipt of the Weeks Expense Fee Base Amount would       
satisfy in whole or in part the REIT Requirements, in which event Duke shall pay
to Weeks OP the lessor of the unpaid Weeks Expense Fee Base Amount. Duke's      
obligation to pay any unpaid portion of the Weeks Break-Up Expenses (provided   
Duke has otherwise complied with its obligations under this provision) shall    
terminate (and any amount still held in such escrow shall be released to Duke)  
on the date that is five years from the date the Weeks Break-Up Expenses first  
become due under this Agreement.                                                

    (d)  In the event that any of Duke or Weeks is required to file suit to seek
all or a portion of the amounts payable under this Section 8.2, and such party  
prevails in such litigation, such party shall be entitled to all expenses,      
including attorney's fees and expenses which it has incurred in enforcing its   
rights hereunder; PROVIDED that such expenses shall be considered part of       
out-of-pocket expenses incurred in connection with this Agreement and the other 
transactions within the definition of Duke Break-Up Expenses or Weeks Break-Up  
Expenses, as the case may be.                                                   

 Section 8.3.  EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either Weeks or Duke as provided in Section 8.1, this Agreement    
shall forthwith become void and have no effect, without any liability or        
obligation on the part of Duke, or Weeks, other than the last sentence of       
Section 5.2, Section 8.2, this Section 8.3 and Article IX and except to the     
extent that such termination results from a willful breach by a party of any of 
its representations, warranties, covenants or agreements set forth in this      
Agreement.                                                                      

 Section 8.4.  AMENDMENT.  This Agreement may be amended by the parties in
writing by action of their respective Boards of Directors at any time before or 
after any Stockholder Approvals, the Weeks OP Approvals and the Duke OP         
Approvals are obtained and prior to the filing of the Articles of Merger for the
Merger with the Secretary of State of Indiana and the Secretary of State of     
Georgia and a certificate of merger for the OP Merger with the Office of the    
Secretary of State of Indiana and the Office of the Secretary of State of       
Georgia; PROVIDED, HOWEVER, that, after any of the Stockholder Approvals, the   
Weeks OP Approvals and the Duke OP Approvals are obtained, no such amendment,   
modification or supplement shall alter the amount or change the form of the     
consideration to be delivered to Weeks' or Duke's shareholders or alter or      
change any of the terms or conditions of this Agreement if such alteration or   
change would adversely affect Weeks' shareholders or Duke's shareholders, or the
Weeks Limited Partners or Duke Limited Partners.                                

  Section 8.5.  EXTENSION; WAIVER.  At any time prior to the Effective Time,
each of Weeks and Duke may (a) extend the time for the performance of any of the
obligations or other acts of the other party,

Agreement or (c) subject to the proviso of Section 8.4, waive compliance with   
any of the agreements or conditions of the other party contained in this        
Agreement. Any agreement on the part of a party to any such extension or waiver 
shall be valid only if set forth in an instrument in writing signed on behalf of
such party. Any waivers pursuant to clause (c) of the second preceding sentence 
(i) of the provisions of Section 4.1(e) may be given in writing by or on behalf 
of Duke by the chief executive officer of Duke and (ii) of the provisions of    
Section 4.2(e) may be given in writing by or on behalf of Weeks by the chief    
executive officer of Weeks. The failure of any party to this Agreement to assert
any of its rights under this Agreement or otherwise shall not constitute a      
waiver of those rights.

    You have asked us whether, in our opinion, the Exchange Ratio is fair from a
financial point of view to Duke.                                                

In arriving at the opinion set forth below, we have, among other things:

(1) Reviewed certain publicly available business and financial    
  information relating to Duke and Weeks which we deemed to be
relevant;                                                 

       (2) Reviewed certain information, including financial forecasts, relating
           to the business, earnings, funds from operations, adjusted funds from
          operations, cash flow, assets, liabilities and prospects of Duke and
        Weeks furnished to us by Duke and Weeks, as well as the amount and
         timing of the savings and related synergies expected to result from
        the Transaction (the "Expected Synergies") furnished to us by Duke
and Weeks;                                                

     (3) Conducted discussions with members of senior management of Duke and
          Weeks concerning the matters described in clauses (1) and (2) above,
         as well as their respective business and prospects before and after
  giving effect to the Transaction and the Expected Synergies;

    (4) Reviewed the market prices and valuation multiples for Duke Shares
       and Weeks Shares and compared them with those of certain publicly
traded companies that we deemed relevant;                 

   (5) Reviewed the results of operations of Duke and Weeks and compared
         them with those of certain publicly traded companies that we deemed
to be relevant;

   (6) Compared the proposed financial terms of the Transaction with the
         financial terms of certain other transactions which we deemed to be
relevant;                                                 

(7) Participated in certain discussions and negotiations among    
     representatives of Duke and Weeks and their financial and legal
advisors;                                                 

     (8) Reviewed the potential pro forma impact of the Transaction on Duke;

    (9) Reviewed a draft of the Merger Agreement, dated February 25, 1999;
and                                                       

   (10) Reviewed such other financial studies and analyses and took into
      account such other matters as we deemed necessary, including our
      assessment of general economic, real estate, market and monetary
conditions.                                               

In preparing our opinion, we have assumed and relied on the accuracy and
completeness of all information supplied or otherwise made available to us,     
discussed with or reviewed by or for us, or publicly available, and we have not 
assumed any responsibility for independently verifying such information or      
undertaken an independent evaluation or appraisal of any of the assets or       
liabilities of Duke or Weeks. With respect to the financial forecast information
and the Expected Synergies furnished to or discussed with us by Duke or Weeks,  
we have assumed that they have been reasonably prepared and reflect the best    
currently available estimates and judgment of Duke's or Weeks' management as to 
(a) the expected future financial performance of Duke or Weeks, as the case may 
be, and (b) the Expected Synergies. We have further assumed that the Transaction
will qualify as a tax-free reorganization for United States federal and any     
applicable state income tax purposes. We have also assumed that the Transaction 
will not change the Real Estate Investment Trust status of the pro forma entity 
for federal income tax purposes, and that the final form of the Merger Agreement
will be substantially similar to the draft reviewed by us.                      

Our opinion is necessarily based upon market, real estate, economic and 
other conditions as they exist and can be evaluated on, and on the information  
made available to us as of, February 26, 1999. We have assumed that, in the     
course of obtaining the necessary regulatory or other consents or approvals     
(contractual or otherwise) for the Transaction, no restrictions, including any  
divestiture requirements or amendments or modifications, will be imposed that   
will have a material adverse effect on the contemplated benefits of the         
Transaction or the Expected Synergies.                                          

We are acting as financial advisor to Duke in connection with the       
Transaction and will receive a fee from Duke for our services, which is         
contingent upon the consummation of the Transaction. In addition, Duke has      
agreed to indemnify us for certain liabilities arising out of our engagement. We
have, in the past, provided financial advisory services to Duke and may continue
to do so and have received, and may receive, fees for the rendering of such     
services. In addition, in the ordinary course of our business, we may actively  
trade the securities of Duke or Weeks, for our own account and for the accounts 
of customers, and, accordingly, may at any time hold a long or short position in
such securities.                                                                

   This opinion is solely for the use and benefit of the Board of Directors of
Duke. Our opinion does not address the merits of the underlying decision by Duke
to engage in the Transaction and does not constitute a recommendation to any    
shareholder of Duke as to how such shareholder should vote on the Transaction.  
We are not expressing any opinion as to the prices at which any of Duke Shares  
will trade following the announcement or consummation of the Transaction. On the
basis of and subject to the foregoing, we are of the opinion that, as of the    
date hereof, the Exchange Ratio is fair from a financial point of view to Duke. 

                 Very truly yours,

                                     MERRILL LYNCH, PIERCE, FENNER & SMITH

Gentlemen:                                                                      

   You have requested our opinion as to the fairness from a financial point of
view to the holders of the outstanding shares of Common Stock, par value $0.01  
per share (the "Weeks Common Stock"), of Weeks Corporation ("Weeks") of the     
exchange ratio of 1.38 shares of Common Stock, par value $0.01 per share (the

for each outstanding share of Weeks Common Stock (the "Exchange Ratio") pursuant

Goldman, Sachs & Co., as part of its investment banking business, is    
continually engaged in the valuation of businesses and their securities in      
connection with mergers and acquisitions, negotiated underwritings, competitive 
biddings, secondary distributions of listed and unlisted securities, private    
placements and valuations for estate, corporate and other purposes. We are      
familiar with Weeks having provided certain investment banking services to Weeks
from time to time, including having acted as (i) lead-managing underwriter of a 
public offering of 2.25 million shares of Weeks Common Stock in November 1996,  
(ii) lead-managing underwriter of a public offering of 3.2 million shares of    
Weeks Common Stock in May 1997, (iii) lead-managing underwriter of a public     
offering of $150 million Series A Cumulative Redeemable Preferred Stock of Weeks
in October 1997, (iv) lead-managing underwriter of a public offering of $100    
million 6.875% Notes due 2005 of Weeks in March 1998, and (v) lead-managing     
underwriter of a public offering of $100 million 7.375% Notes due 2007 of Weeks 
in July 1998, and (vi) its financial advisor in connection with, and having     
participated in certain negotiations leading to, the Agreement. We have also    
provided certain investment banking services to Duke from time to time,         
including having acted as (i) lead-managing underwriter of a public offering of 
$100 million Puttable Reset Securities PURS (SM) due 2016 of Duke in March 1998 
and (ii) sole underwriter of a public offering of 1.5 million shares of Duke    
Common Stock in November 1998 and may continue to provide investment banking    
services to Duke in the future. Goldman Sachs provides a full range of financial

  In connection with this opinion, we have reviewed, among other things, the
Agreement; Annual Reports to Stockholders and Annual Reports on Form 10-K of    
Weeks for the four years ended December 31, 1997, and in the case of Duke for   
the five years ended December 31, 1997; certain interim reports to stockholders 
and Quarterly Reports on Form 10-Q of Weeks and Duke; certain other             
communications from Weeks and Duke to their respective stockholders; and certain
internal financial analyses and forecasts for Weeks and Duke prepared by their  
respective managements, including certain cost savings and operating synergies  
projected by the management of Weeks to result from the transaction. We also    
have held discussions with members of the senior management of Weeks and Duke   
regarding the strategic rationale for, and the potential benefits of, the       
transaction contemplated by the Agreement and the past and current business     
operations, financial condition and future prospects of their respective        
companies. In addition, we have reviewed the reported price and trading activity
for the Weeks Common Stock and Duke Common Stock, compared certain financial and
stock market information for Weeks and Duke with similar information for certain
other companies the securities of which are publicly traded, reviewed the       
financial terms of certain recent business combinations in the real estate      
industry specifically, and in other industries generally, and performed such    
other studies and analyses as we considered appropriate.                        

 We have relied upon the accuracy and completeness of all of the financial
and other information reviewed by us and have assumed such accuracy and         
completeness for purposes of rendering this opinion. In addition, we have not   
made an independent evaluation or appraisal of the assets and liabilities of    
Weeks or Duke or any of their respective subsidiaries and we have not been      
furnished with any such evaluation or appraisal. Our advisory services and the  
opinion expressed herein are provided for the information and assistance of the 
Board of Directors of Weeks in connection with its consideration of the         
transaction contemplated by the agreement and such opinion does not constitute a
recommendation as to how any holder of Weeks Common Stock should vote with      
respect to such transaction.                                                    

    Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that as of the date hereof the Exchange 
Ratio pursuant to the Agreement is fair from a financial point of view to the   
holders of Weeks Common Stock.                                                  

Very truly yours,

Corporation to the fullest extent authorized by the Indiana Business    
    Corporation Law, as the same exists or may hereafter be amended (but, in the
  case of any such amendment, only to the extent that such amendment permits
the Corporation to provide broader indemnification rights than said law 
  permitted the Corporation to provide prior to such amendment), against all
 expense, liability and loss (including attorneys' fees, judgments, fines,
ERISA excise taxes or penalties and amounts paid or to be paid in       
settlement) reasonably incurred or suffered by such Person in connection
therewith and such indemnification shall continue as to a Person who has
  ceased to be a Director, officer, employee or agent and shall inure to the
benefit of his or her heirs, executors and administrators: PROVIDED,    
  HOWEVER, that, except as provided in paragraph (b) hereof, the Corporation
    shall indemnify any such Person seeking indemnification in connection with a
proceeding (or part thereof) initiated by such Person only if such      
    proceeding (or part thereof) was authorized by the Board of Directors of the
 Corporation. The right to indemnification conferred in this Section 13.02
shall be a contract right and shall include the right to be paid by the 
Corporation the expenses incurred in defending any such proceeding in   
 advance of its final disposition: PROVIDED, HOWEVER, that, if the Indiana
   Business Corporation Law requires, the payment of such expenses incurred by
  a Director or officer in his or her capacity as a Director or officer (and
    not in any other capacity in which service was or is rendered by such Person
 while a Director or officer, including, without limitation, service to an
   employee benefit plan) in advance of the final disposition of a proceeding,
    shall be made only upon delivery to the Corporation of an undertaking, by or
  on behalf of such Director or officer, to repay all amounts so advanced if
it shall ultimately be determined that such Director or officer is not  
entitled to be indemnified under this Section 13.02 or otherwise. The   
Corporation may, by action of its Board of Directors, provide           
indemnification to employees and agents of the Corporation with the same
    scope and effect as the foregoing indemnification of Directors and officers.

      (b) RIGHT OF CLAIMANT TO BRING SUIT. If a claim under paragraph (a) of
    this Section 13.02 is not paid in full by the Corporation within thirty days
    after a written claim has been received by the Corporation, the claimant may
at any time thereafter bring suit against the Corporation to recover the
unpaid amount of the claim and, if successful in whole or in part, the  
  claimant shall be entitled to be paid also the expense of prosecuting such
claim. It shall be a defense to any such action (other than an action   
    brought to enforce a claim for expenses incurred in defending any proceeding
  in advance of its final disposition where the required undertaking, if any
is required, has been tendered to the Corporation)

that the claimant has not met the standards of conduct which make it    
  permissible under the Indiana Business Corporation Law for the Corporation
   to indemnify the claimant for the amount claimed, but the burden of proving
such defense shall be on the Corporation. Neither the failure of the    
    Corporation (including its Board of Directors, independent legal counsel, or
   its Shareholders) to have made a determination prior to the commencement of
such action that indemnification of the claimant is proper in the       
  circumstances because he or she has met the applicable standard of conduct
set forth in the Indiana Business Corporation Law, nor an actual        
determination by the Corporation (including its Board of Directors,     
 independent legal counsel, or its Shareholders) that the claimant has not
    met such applicable standard of conduct, shall be a defense to the action or
   create a presumption that the claimant has not met such applicable standard
of conduct.                                                             

   (c) NON-EXCLUSIVITY OF RIGHTS. The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its
   final disposition conferred in this Section 13.02 shall not be exclusive of
any other right which any Person may have or hereafter acquire under any
statute, provision of these Articles, by-law, agreement, vote of        
Shareholders or disinterested Directors or otherwise.                   

      (d) INSURANCE. The Corporation may maintain insurance, at its expense,
to protect itself and any Director, officer, employee or agent of the   
Corporation or another corporation, partnership joint venture, trust or 
    other enterprise against any such expense, liability or loss, whether or not
  the Corporation would have the power to indemnify such Person against such
expense, liability or loss under the Indiana Business Corporation Law.

SEVERABILITY

In the event that any Article or Section (or portion thereof) of these  
Articles shall be found to be invalid, prohibited or unenforceable for any      
reason, the remaining provisions, or portion thereof, of these Articles shall be

invalid, prohibited or unenforceable provision had been stricken herefrom or

Articles remain, to the fullest extent permitted by law, applicable and

DUKE'S DIRECTOR AND EXECUTIVE COMPENSATION INFORMATION

COMMITTEES OF THE BOARD OF DIRECTORS OF DUKE                                    

  The Board of Directors of Duke met four times during the last fiscal year.
The Board of Directors of Duke has an Asset Committee, an Audit Committee, an   
Executive Compensation Committee, a Finance Committee and a Nominating          
Committee.                                                                      

The function of the Asset Committee is to discuss, review and authorize 
business transactions that exceed established guidelines. The members of the    
Asset Committee are Messrs. Baur, Feinsand, Peterson, Strauss and Zink and Ms.  
Cuneo. Mr. Strauss served as the Committee's chairman. The Committee met 12     
times in 1998.                                                                  

    The function of the Audit Committee is to evaluate audit performance, handle
relations with Duke's independent auditors and evaluate policies and procedures 
related to internal accounting controls. The members of the Audit Committee are 
Messrs. Button, Feinsand, Lytle and Peterson and Ms. Cuneo. Mr. Feinsand served 
as the Committee's chairman. The Committee met three times during 1998.         

  The function of the Executive Compensation Committee is to review and make
recommendations to the Board of Directors with respect to the compensation of   
directors, officers, and employees of Duke, to implement Duke's long term       
compensation plans and other employee benefit plans and to make recommendations 
to the Nominating Committee regarding individuals qualified to be nominated as  
unaffiliated directors. The members of the Executive Compensation Committee are 
Messrs. Button, Lytle, Rogers and Strauss and Ms. Cuneo. Mr. Button served as   
the Committee's chairman. The Committee met five times during 1998.             

   The function of the Finance Committee is to review, recommend and authorize
certain debt financing and equity transactions. The members of the Finance      
Committee are Messrs. Baur, Button, Feinsand, Rogers, Staton, Strauss and Zink. 
Mr. Rogers served as the Committee's chairman. The committee met six times      
during 1998.                                                                    

    The function of the Nominating Committee is to nominate individuals to serve
as directors. The Nominating Committee is comprised of all of the unaffiliated  
directors, Messrs. Button, Feinsand, Lytle, Peterson, Rogers and Strauss and Ms.
Cuneo. The committee does not formally consider nominations by shareholders. Mr.
Button served as the Committee's chairman. The Committee met once during 1998.  

 In 1998, all directors attended at least 75% of the meetings of the Board
and all committees of the Board of which they were members except for Mr.       
Rogers. Mr. Rogers attended 100% of the Board of Directors meetings, but his    
overall attendance at all Board and committee meetings was less than 75%.       

DIRECTOR EMERITUS                                                               

At the annual meeting of shareholders, Duke will confer the title of    
Director Emeritus upon John W. Wynne, who does not intend to stand for          
re-election as a Director this year. Mr. Wynne has served Duke as a Director    
with exemplary skill and loyalty since Duke was established and was one of the  
founders of Duke in 1972. The entire Duke organization wishes to express its    
gratitude and admiration for Mr. Wynne's outstanding service throughout his     
career and looks forward to many more years of his valuable counsel in the role 
of Director Emeritus.                                                           

COMPENSATION OF DIRECTORS                                                       

 Each non-employee director receives 1,200 common shares of Duke as annual
compensation. Non-employee directors also receive a fee of $2,500 for attendance
at each meeting of the Board of Directors. In addition, the non-employee        
directors receive $500 for participation in each telephonic meeting of the Board
and for participation in each committee meeting not held in conjunction with a  
regularly scheduled Board meeting. Officers of Duke who are also directors      
receive no additional compensation for their services as directors.

    Beginning in 1999, certain Directors will receive grants of stock option and
dividend increase units under the 1999 Directors Stock Option and Dividend      
Increase Unit Plan of Duke Realty Investments, Inc. Pursuant to this plan,      
Directors that do not receive grants of stock options under any other Duke plan 
for a year will receive a grant of 2,500 stock options and 2,500 dividend       
increase units at the first meeting of Duke's Executive Compensation Committee  
of each year. However, for 1999 only, Directors that have never been granted    
stock options under a Duke plan will receive a grant of 7,500 stock options and 
7,500 dividend increase units.

BENEFICIAL OWNERSHIP REPORTING COMPLIANCE                                       

  Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
Duke's officers and directors, and persons who beneficially own more than 10% of
Duke common shares, to file reports of ownership and changes in ownership with  
the Securities and Exchange Commission. Based on a review of these forms, Duke  
believes that during 1998 all of its officers, directors and greater than 10%   
beneficial owners timely filed the forms required under Section 16(a).          

REPORT OF EXECUTIVE COMPENSATION COMMITTEE                                      

EXECUTIVE COMPENSATION PHILOSOPHY                                       

The primary objectives of the Executive Compensation Committee (the     
"Committee") of the Board of Directors in determining total compensation of     
Duke's executive officers are (1) to enable Duke to attract and retain high     
quality executives by providing total compensation opportunities with a         
combination of compensation elements which are at or above competitive          
opportunities and which provide for moderate fixed costs and leveraged incentive
opportunities, and (2) to align shareholder interests and executive rewards by  
providing substantial incentive opportunities to be earned by meeting           
pay-for-performance standards designed to increase long-term shareholder value. 
In order to accomplish

these objectives, the Committee adopted in 1995 an executive compensation       
program which provides (x) annual base salaries at or near the market median,   
(y) annual incentive opportunities which reward the executives for achieving or 
surpassing performance goals which represent industry norms of excellence, and  
(z) long-term incentive opportunities which are directly related to increasing  
shareholder value.                                                              

  Section 162(m) of the Internal Revenue Code of 1986, as amended, imposes a
limitation on the deductibility of nonperformance based compensation in excess  
of $1 million paid to certain executive officers. The Compensation Committee's  
policy with respect to Section 162(m) is to make every reasonable effort to     
ensure that compensation is deductible to the extent permitted, while           
simultaneously providing executives appropriate awards for their performance.   
Duke's long-term incentive plans have been designed to comply with the          
performance-based requirements of Section 162(m).                               

BASE SALARIES AND ANNUAL CASH INCENTIVES                                

    The range of base salaries for the executive officers of Duke is established
after a review by the Committee of the salaries paid to executive officers of a 
comparison group of other publicly traded real estate investment trusts. Other  
subjective factors are considered such as the individual's experience and       
performance.                                                                    

   An annual cash incentive range is established for each executive officer at
the beginning of the year. The actual annual cash incentive paid to each        
executive is determined based on his or her ability to impact measurable        
results. The amount of each executive's annual award is based on a combination  
of three performance factors: (1) overall corporate performance; (2) business   
segment or departmental performance; and (3) individual performance. The        
relative importance of each of the performance factors in determining annual    
cash incentives differs for each executive position with the performance factor 
for the most senior executives being based more heavily on overall corporate    
performance and the performance factor for the officers in-charge of business   
segments or departments being based more heavily on the performance of their    
segment or department. The overall corporate performance factor is based on a   
three-tier measurement system consisting of Funds from Operations Growth Per    
common share, Return on Shareholders' Equity and                                

    Return on Real Estate Investments. The business segment performance is based
on certain financial measurements, including the volume and yield of new        
acquisitions and developments, performance of the in-service property portfolio,
and the business segment's operating income contribution to Duke. The amount of 
the targeted annual cash incentives paid is based on the perceived level of     
attainment of each of the measurements by the Committee.                        

LONG-TERM INCENTIVE OPPORTUNITIES                                       

The amount of long-term incentive compensation awarded to officers and  
executives on an annual basis is determined at the discretion of the Committee  
but is tied to overall corporate and business segment performance, the          
participant's level of responsibility within Duke and the participant's         
individual performance. The long-term incentive opportunities consist of        
approximately two-thirds Stock Options ("Options") and Dividend Increase Units  
("DIUs") and one-third Shareholder Value Grants.                                

STOCK OPTION AND DIVIDEND INCREASE UNIT PLANS                           

  The objectives of the Stock Option and Dividend Increase Unit Plans are to
provide executive officers with long-term incentive opportunities aligned with  
the shareholder benefits of an increased common share value and increased annual
dividends. The number of Options and DIUs issued to each executive annually is  
set by the Committee based on the goal of providing approximately two-thirds of 
the total annual long-term incentive award through these plans. The Options and 
DIUs are for terms of no more than ten years. With certain limited exceptions,  
awards made under the Stock Option and Dividend Increase Unit Plans vest 20     
percent per year over a five-year period. The Options may not be issued for

less than the fair market value of Duke's common shares at the date of grant.   
The value of each DIU at the date of exercise will be determined by calculating 
the percentage of Duke's annualized dividend per share to the market value of   
one common share (the "Dividend Yield") at the date the DIU is granted and      
dividing the increase in Duke's annualized dividend from the date of grant to   
the date of exercise by such Dividend Yield. A DIU may be exercised by a        
participant only to the extent that such participant has exercised an Option to 
purchase a common share of Duke under an Option granted under the 1995 Stock    
Option Plan on the same date as the grant of the DIU.                           

SHAREHOLDER VALUE PLAN                                                  

    The objective of the Shareholder Value Plan is to provide executive officers
with long-term incentive opportunities directly related to providing total      
shareholder return in excess of the median of independent market indices. The   
annual Shareholder Value Plan amount for each executive is set by the Committee 
with the goal of providing approximately one-third of the total long-term       
incentive award through this plan. The award vests entirely three years after   
the date of grant and the amount paid is based on Duke's total shareholder      
return for such three year period as compared to independent market indices. The
independent market indices used for comparison are the S&P 500 Index and the    
NAREIT Equity REIT Total Return Index. The amount of the award payable may range
from zero percent if both of the rankings of the comparable returns are less    
than the 50th percentile of both of the indices to 300 percent if the rankings  
of both of the comparable returns are in the 90th percentile or higher of both  
of the indices, with 100 percent of the award being payable at the 60th         
percentile.                                                                     

COMPENSATION OF CHIEF EXECUTIVE OFFICER                                 

The compensation awarded to Mr. Hefner in 1998 consisted primarily of an
annual base salary, an annual cash incentive award, and grants under Duke's     
long-term incentive plans. The total compensation paid to Mr. Hefner has        
historically resulted in total compensation that is below the comparable market 
median but is considered appropriate in light of Mr. Hefner's substantial equity
interest in Duke and his stock options held.                                    

   BASE SALARY.  The Committee intends to gradually increase Mr. Hefner's base
salary with the intent that, by 1999, his base salary will be equal to 90       
percent of the market median of a comparison group of thirteen other publicly   
traded real estate investment trusts. Mr. Hefner's annual base salary for 1998  
was $195,000.                                                                   

  ANNUAL CASH INCENTIVE.  Under the Committee's executive compensation plan,
Mr. Hefner is eligible for a targeted annual cash incentive bonus. The amount of
Mr. Hefner's annual cash incentive bonus is determined solely upon overall      
corporate performance which is based on a three-tier measurement system         
consisting of Funds from Operations Growth Per common share, Return on          
Shareholders' Equity and Return on Real Estate Investments as compared to       
pre-determined target criteria established by the Committee. The amount of the  
targeted annual cash incentives paid is based on the level of attainment of each
of the measurements as compared to the pre-determined targets. For 1998, Duke's 
FFO Growth was 18.13% per common share, its Return on Shareholders' Equity was  
12.16% and its Return on Real Estate Investments was 9.59%. Based on these      
results versus the pre-determined targets established by the Committee, Mr.     
Hefner received an Annual Cash Incentive award of $250,000 for 1998.            

 LONG-TERM INCENTIVE OPPORTUNITY AWARD.  Mr. Hefner is also eligible for a
targeted long-term incentive award with a value equal to a percentage of his    
annual base salary. The long-term incentive opportunity award granted to Mr.    
Hefner in 1998 consisted of (1) the grant of an option to purchase 18,960 common
shares at a price of $24.25 per share, (2) the grant of 18,960 DIUs with a      
Dividend Yield of 4.95%, and (3) the award of a targeted amount of $66,667 under
the Shareholder Value Plan.

In January 1998, Mr. Hefner received a payment of $53,460 pursuant to a 
grant under the Shareholder Value Plan made in 1995. In February 1999, Mr.      
Hefner received a payment of $64,238 pursuant to a grant under the Shareholder  
Value Plan made in 1996. The payout percentages of these awards as determined by
formulas contained in the plan were 178% and 214% for the grants made in 1995   
and 1996, respectively.                                                         

STOCK PURCHASE PLANS                                                    

In 1998, the Board of Directors adopted the Executive and Senior Officer
Stock Purchase Plan of Duke Realty Investments, Inc. (the "Officer Stock        
Purchase Plan") and the Director Stock Purchase Plan of Duke Realty Investments,
Inc. (the"Director Stock Purchase Plan"). The purpose of these plans is to more 
closely align officer and Director financial rewards with the financial rewards 
realized by Company shareholders, increase officer and Director motivation to   
manage Duke as equity owners, retain key employees and increase the ownership of
common shares by officers and directors. On August 25, 1998, under the Officer  
Stock Purchase Plan, certain officers of Duke received options to purchase      
1,231,215 common shares at $21.625 per share (the closing price of a common     
share on that date). On that same date, the officers exercised these options by 
purchasing 1,231,215 common shares from Duke at $21.625 per share. From August  
26, 1998 through August 31, 1998, certain Directors of Duke purchased 402,335   
common shares under the Director Stock Purchase Plan in the open market at an   
average price of $21.623 per share.                                             

 All officers and Directors participating in the plans borrowed the entire
purchase price of the shares from KeyBank, N.A. and are personally obligated to 
repay the loans. The Operating Partnership has unconditionally guaranteed the   
payment and performance obligations of the officers and Directors to KeyBank,   
N.A. Each participant is personally liable to the Operating Partnership for any 
payments made by the Operating Partnership under the guarantee as a result of   
default by such participant on their KeyBank, N.A. loan.                        

SALARY REPLACEMENT PLAN                                                 

   In January 1999, subject to shareholder approval, the Committee adopted the
1999 Salary Replacement Stock Option and Dividend Increase Unit Plan of Duke    
Realty Investments, Inc. (the "Salary Replacement Plan"). The purpose of this   
plan is to encourage additional equity ownership in Duke by key officers. Under 
this plan, certain officers may elect to receive Options and DIUs in lieu of the
receipt of all or a portion of their base salary, annual incentive bonus or     
Shareholder Value Plan payments. The number of Options and DIUs granted under   
the Salary Replacement Plan will be based on the amount of forgone compensation 
elected by a participant divided by the Committee's determination of the value  
of an Option/DIU. The exercise price of an option may not be less than the fair 
market value of Duke's common shares at the date of grant. All awards made under
the Salary Replacement Plan will vest on the date of grant.                     

EMPLOYMENT AND SEVERANCE AGREEMENTS                                     

In April 1998, the Committee adopted the Duke Realty Severance Pay Plan.
This plan provides for the payment of severance amounts to certain key officers 
if, within one year of a change in control of Duke, employment is terminated by 
Duke other than "for cause" or if an officer voluntarily terminates employment  
because of a reduction in the officer's pay or his forced relocation. A "Level  
One" participant will receive two times the sum of the compensation awarded to  
such terminated participant for the calendar year preceding the date of         
termination and a "Level Two" will receive one times his prior year             
compensation. The only participants of the plan at this time are Messrs. Burk,  
Chapman, Hefner, Horn, Linville, Oklak and Zink. The Committee has designated   
each of these participants as eligible for Level One benefits.

STOCK OPTION GRANTS IN 1998 

  The following table sets forth certain information for the Named Executive

(1) The dollar amounts under these columns are the result of calculations at the
5% and 10% rates set by the Securities and Exchange Commission and,     
   therefore, are not intended to forecast future appreciation of Duke's stock
   price. For the options expiring on January 28, 2008, Duke's per share stock
price would be $39.50 and $62.90 if increased 5% and 10%, respectively, 
compounded annually over the 10-year option term.                       

(2) These options were granted in connection with the Officer Stock Purchase    
Plan. Under that plan, the participants were required to exercise the   
options the same day they were granted. The grant price and the exercise
 price were each equal to the fair market value of one common share on the
date of grant.                                                          

The following table presents certain information for the Named Executive
Officers relating to the exercise of stock options during 1998 and, in addition,
information relating to the valuation of unexercised stock options.

------------------------                                                        

(1) Under the 1995 Dividend Increase Unit Plan, DIUs are granted to key         
   employees. DIUs vest over a five-year period at 20% per year. A participant
  may exercise DIUs only to the extent that such participant has purchased a
   common share pursuant to an option granted under the 1995 Stock Option Plan
   on the same date as the grant of the DIU. The value of each DIU at the date
   of exercise is determined by calculating the Dividend Yield at the date the
   DIU is granted and dividing the increase in Duke's annualized dividend from
  the date of grant to the date of exercise by such Dividend Yield. DIUs not
  exercised within 10 years of the date of grant are forfeited. Distribution
   of a participant's benefits under the 1995 Dividend Increase Unit Plan will
 be made in a single lump sum payment in the form of Duke's common shares.
The "In-the-Money" value of vested DIUs at December 31, 1998 for these  
executives was $104,402 for Messrs. Hefner, Zink and Burk, $178,247 for 
    Messrs. Horn and Linville, $6,936 for Mr. Chapman and $52,841 for Mr. Oklak.

(2) Under the 1995 Shareholder Value Plan, awards are granted in specified      
   dollar amounts to selected key employees. The specified award is payable to
the participant on the third anniversary of the grant of the award. The 
actual payments under the plan will be determined based upon Duke's     
  cumulative total shareholder return for the three year period beginning on
    the date of grant as compared to the cumulative total return for the S&P 500
   Index and the NAREIT Equity REIT Total Return Index (the "Indices") for the
same period. Duke's cumulative total shareholder return is calculated by
   determining the average per share closing price of Duke's common shares for
    the 30 day period preceding the end of the three year period increased by an
 amount that would be realized if all cash dividends paid during the three
year period were reinvested in common shares of Duke and comparing this 
 amount to the average per share closing price of Duke's common shares for
 the 30 day period preceding the date of grant. The payment of one-half of
the bonus award is adjusted based upon the percentile

    ranking of Duke's cumulative total shareholder return as compared to each of
   the Indices for the same period. The payment adjustment may range from zero
percent of the amount awarded if both of the rankings of the comparable 
returns are less than the 50th percentile of both of the Indices to 300 
percent of the amount awarded if both of the rankings are in the 90th   
  percentile or higher of both of the Indices, with 100 percent of the award
being payable at the 60th percentile. Distribution of a participant's   
  adjusted bonus award at the end of the three-year period after the date of
grant will be made one-half in cash and one-half in the form of common  
shares of Duke. The amount of the awards payable to these executives on 
 December 31, 1998 was $64,238 for Messrs. Hefner, Zink, and Burk, $85,650
for Messrs. Linville and Horn, and $39,256 for Mr. Oklak.               

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION                     

   Ms. Cuneo, Mr. Lytle and Mr. Strauss serve on Duke's Executive Compensation
Committee. Duke contracted with an affiliate of Conseco, Inc. during 1998 for   
certain construction and insurance related services. Ms. Cuneo is an Executive  
Vice President and director of Conseco, Inc. In 1998, Duke received $561,000 in 
construction related fees from a Conseco, Inc. affiliate and paid a Conseco,    
Inc. affiliate $1,522,000 in insurance premiums.                                

Duke leases office space to affiliates of Anthem, Inc. Mr. Lytle is     
Chairman, President and Chief Executive Officer of Anthem, Inc. Under the       
leases, which have lease rates comparable to similar space in the area, Duke    
received total rental income of $1,756,000 in 1998.                             

In connection with the acquisition of an eight building portfolio of    
properties with a total purchase price of $16.2 million, Duke paid Regent Realty

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS                                  

    A wholly owned subsidiary of Duke is the sole general partner of Duke Realty
Services Limited Partnership (the "Services Partnership"), which is in turn the 
sole general partner of Duke Construction Limited Partnership (the "Construction
Partnership"). The operations of these entities are included in the consolidated
financial statements of Duke. The Services Partnership provides third-party     
property management, leasing, construction management and development services  
and the Construction Partnership provides third-party construction services.    
Certain of the executive officers own limited partnership interests in these    
entities. Thomas L. Hefner, Daniel C. Staton, Darell E. Zink, Jr., John W.      
Wynne, Gary A. Burk and David R. Mennel, all of whom are officers or Directors  
of Duke, control DMI Partnership ("DMI"), which owns ninety percent of the      
capital interests of the Services Partnership and a profits interest which      
varies from ten percent to ninety percent. The share of net income of the       
Services Partnership allocated to DMI in 1998 was $1,211,000. DMI's share of net
income from the Services Partnership is included in minority interest in Duke's 
financial statements. Duke has an option to acquire DMI's interest in the       
Services Partnership in exchange for 833,334 common shares. Duke is required to 
purchase DMI's interest in the Services Partnership for 833,334 common shares   
upon a change in control of Duke or the dissolution of the Operating            
Partnership. DMI also indirectly owns a ninety-five percent limited partnership 
interest in the Construction Partnership, which Duke has the option to purchase 
for $1,000. The Construction Partnership has a deficit cumulative capital       
balance; thus there was no allocation of net income to any of the partners of   
the Construction Partnership, including DMI.

  The Services Partnership and the Construction Partnership provide property
management, leasing, construction and other tenant related services to          
properties in which Messrs. Hefner, Staton, Zink, Wynne, Burk and Mennel have   
ownership interests. Duke has an option to acquire these executive officers'    
interests in these properties (the "Option Properties"). In 1998, the Services  
Partnership and the Construction Partnership received fees of $2,247,000 for    
services provided to the Option Properties. The fees charged by the Services    
Partnership and the Construction Partnership for such services are equivalent to
those charged to other third-party owners for similar services except for one   
property. Pursuant to an agreement with this property's lender, the payment of  
75% of the fees was deferred and payable only from excess sale or refinancing   
proceeds. Duke agreed to this deferral in 1997 in order to retain certain       
contracts for services provided to other properties owned by the lender. In     
1998, Duke acquired this loan from the third party lender and all such deferred 
fees have been paid.                                                            

  Duke also leased operating facilities in certain of the Option Properties.
In 1998, the aggregate rent under such leases was approximately $21,309. The    
rental amount paid is comparable to similar space in the area.                  

The Operating Partnership has a $20.0 million loan to the Services      
Partnership, which requires interest only payments at 12% through September,    
2003. The loan then amortizes over a 15-year period with interest at 12% until  
final maturity in September, 2018. The loan is guaranteed by an entity owned    
indirectly by Messrs. Hefner, Staton, Zink, Wynne, Burk and Mennel. The         
Operating Partnership also provides working capital financing to the Services   
Partnership at a rate of prime plus 1%.                                         

  Messrs. Hefner, Staton, Zink, Wynne, Burk and Mennel, as well as Edward T.
Baur, a Director of Duke, and a corporation controlled by Mr. Baur, have        
personal guarantees for $65.5 million of Duke's debt. The Operating Partnership 
has indemnified them from any liability with respect to such debt.              

  Duke contracts with Steel Frame Erectors, Inc. ("SFE"), an entity owned by
Messrs. Hefner, Staton, Zink, Wynne, Burk and Mennel, for certain               
construction-related services. During 1998, the total costs under these         
contracts for Company related projects were $1,396,000. The construction fees   
earned by SFE on company related projects were $43,000. A 50% owned subsidiary  
of SFE leases space in an office building from a limited liability company      
partially owned by Duke. The subsidiary paid $294,000 under this lease in 1998. 

 In May, 1998 and January, 1999, a partnership 70% owned by Edward T. Baur
contributed land and a building to Duke in return for 101,849 Units of DRLP with
a value of $2.3 million and the assumption of $1.4 million in indebtedness.

ARTICLE III 
BENEFITS

Units under the Plan shall be shares of authorized common stock of the Company  
and may be unissued shares or reacquired shares (including shares purchased in

provisions of this Section 3.1, the maximum number of shares to be delivered    
upon exercise of all Options and Units granted under the Plan shall not exceed  
Five Hundred Thousand (500,000) shares. If the exercise price of any stock      
option granted under the Plan is satisfied by tendering shares to the Company   
(by either actual delivery or by attestation), only the number of shares issued 
net of the shares tendered shall be deemed delivered for purposes of determining
the maximum number of shares available for delivery under the Plan. Shares      
covered by an Option or Unit that are forfeited due to termination of service or
that remain unpurchased or undistributed upon expiration or termination of the  
Option or Unit, respectively, may be made subject to further Options and Units. 

A. STOCK OPTIONS

3.2.  GRANT OF OPTIONS.  For each year during the term of the Plan,

common stock for such calendar year. Provided, however, for the 1999 calendar   
year, each Director who is eligible under Section 2.1 and who, as of the date of

received a grant of stock options from the Company, shall receive an option to  
acquire

Seven Thousand Five Hundred (7,500) shares of the Company's common stock. A     
Director who has previously received a grant of stock options from the Company  
shall be granted an option to acquire Two Thousand Five Hundred (2,500) shares  
of the Company's common stock for the 1999 calendar year.                       

    3.3.  EXERCISE OF OPTIONS.  All rights to exercise an Option shall terminate
ninety (90) days following the date on which a Director ceases to be a Director,
unless the termination of his status as a Director is on account of (i)         
Permanent and Total Disability (ii) death, (iii) retirement after attaining the 
age of 65 years, or (iv) a Change in Control of the Company, but not later than 
the date the Option expires pursuant to its terms. If a Director ceases to be a 
Director due to Permanent and Total Disability or death, the Director, his      
guardian, attorney-in-fact or personal representative, as the case may be, may  
exercise his Options subject to the limitations of this Plan within one (1) year
following the date on which he ceases to be a Director, but not later than the  
date on which the Option expires pursuant to its terms.                         

  3.4.  OPTION PRICE.  The option price per share of stock under each Option
shall be one hundred percent (100%) of the Fair Market Value of the shares on   
the date on which the Option is granted.                                        

 3.5.  OPTION PERIOD.  The option period for each Option granted under the
Plan shall be ten (10) years from the date of grant of such Option. If an Option
is not exercised on or before the tenth anniversary of the date on which it was 
granted, the Option shall expire.                                               

B. DIVIDEND INCREASE UNITS

   3.6.  GRANT OF UNITS.  For each year during the term of the Plan, effective
on the date on which the Committee holds its first quarterly meeting during a   
calendar year, each Director who is eligible under Section 2.1 shall receive a  
grant of Two Thousand Five Hundred (2,500) Units for such calendar year.        
Provided, however, for the 1999 calendar year, each Director who is eligible    
under Section 2.1 and who, as of the date of the first quarterly Board of       
Directors meeting in 1999, has not previously received a grant of stock options 
from the Company, shall receive a grant of Seven Thousand Five Hundred (7,500)  
Units. A Director who has previously received a grant of stock options from the 
Company shall receive a grant of Two Thousand Five Hundred (2,500) Units for the
1999 calendar year.                                                             

  3.7.  EXERCISE OF UNITS.  A Director may exercise his Units subject to the
following requirements:                                                         

        (a) TIMING OF EXERCISE.  A Unit must be exercised on or before the tenth
anniversary of the date on which it was granted; if not exercised on or 
   before that date, the Unit will expire. All rights to exercise a Unit shall
  terminate ninety (90) days following the date on which the Director ceases
  to be a Director, unless the termination of his status as a Director is on
account of (i) Permanent and Total Disability, (ii) death, or (iii)     
   retirement after attaining the age of 65 years, but not later than the date
the Unit expires pursuant to its terms. If a Director ceases to be a    
  Director due to Permanent and Total Disability or death, the Director, his
  guardian, attorney-in-fact or personal representative, as the case may be,
 may exercise his Units subject to the limitations of this Plan within one
(1) year following the date on which he ceases to be a Director, but not
later than the date on which the Unit expires pursuant to its terms.    

        (b) PRIOR EXERCISE OF STOCK OPTIONS.  Units may be exercised only to the
    extent that the same or a greater number of Options have been surrendered by
  the Director through the exercise of Options granted under the Plan on the
    same date on which the Units were granted. Such exercise may have been prior
to or simultaneous with the exercise of such Units. For example, if a   
  Director was granted an Option under the Plan to acquire Two Thousand Five
 Hundred (2,500) shares of the Company's stock and on the same date he was
    granted Two Thousand Five Hundred (2,500) Units under the Plan, the Director
may not exercise the Two Thousand Five Hundred (2,500) Units granted    
   hereunder until he has exercised at least Two Thousand Five Hundred (2,500)
  Options under that stock option grant. Thus, if the Director has exercised
  (or simultaneously surrenders with his exercise of the Units) One Thousand
(1,000) Options under that stock option grant, he may at any time on or 
after the date

    of such acquisition, exercise up to One Thousand (1,000) Units hereunder, as
 long as all the other Plan conditions and limitations have been satisfied
  with respect to such exercise. The shares of Company stock acquired by the
   exercise of an Option on a date other than the date on which the Units were
granted may not be used as a basis for the exercise of such Units.      

        (c) PRIOR NOTICE OF EXERCISE.  The Director must notify the Committee of
  his intent to exercise a Unit by completing an election form authorized by
the Committee and filing such form with the Committee.                  

   3.8.  CALCULATION OF UNIT VALUE.  Upon the exercise date, the Unit or Units
being exercised will be valued for all purposes under the Plan in accordance    
with the following formula. First, the Per Share Value of a share of the        
Company's common stock, as of the effective date on which the Unit was granted, 
will be determined. Second, the quarterly cash dividend rate per share of the   
Company's common stock most recently declared prior to the effective date of the
grant will be determined and annualized (multiplied by four). Third, that       
annualized cash dividend will be divided by the Per Share Value on the effective
date of the grant to set the grant date dividend yield. Fourth, the quarterly   
cash dividend rate per share of the Company's common stock which was most       
recently declared on or before the exercise date will be determined and         
annualized (multiplied by four). Fifth, the annualized cash dividend on the     
effective date of the grant (as determined under the second step) will be       
subtracted from the annualized dividend on the exercise date (as determined     
under the fourth step) to determine the increase in the annualized cash         
dividend. Sixth, the amount of the increase (as determined under the fifth step)
will be divided by the grant date dividend yield (as determined under the third 
step) to establish the Unit's value on the exercise date. For all purposes of   
this Plan, if there is no Per Share Value for Company stock on the date on which
an event which requires the stock to be valued, the per share value shall be the
Per Share Value for Company stock on the trading date immediately preceding the 
date on which the stock is required to be valued.                               

For example, if the Per Share Value of a share of Company stock on the  
effective date of a Unit's grant was $30.00, the quarterly dividend rate on the 
date of grant was $0.49 and the quarterly dividend rate on the date of exercise 
was $0.55, then the Unit's value at exercise would be $3.67, determined under   
the six steps in the preceding paragraph as follows:                            

                                                                [Download Table]
                                                                              
(1) $30.00   [NYSE Closing Price on Date of Grant]                            
(2) $1.96    [$0.49 (Company's Quarterly Cash Dividend on Date of Grant) X 4] 
(3) 6.5333%  [(2) DIVIDED BY (1)]                                             
(4) $2.20    [$0.55 (Company's Quarterly Cash Dividend on Date of Exercise)X4]
(5) $0.24    [$2.20-$1.96 -- Increase in Annualized Cash Dividend]            
(6) $3.67    [(5) DIVIDED BY (3)]                                             

 If the Director had been granted one hundred (100) Units and he exercised
all of those Units, he would be entitled to receive whole shares of Company     
common stock with a value of $367 based on the Per Share Value on the date of   
exercise. (The number of shares to be distributed is described under Section    
4.2).                                                                           

ARTICLE IV
DISTRIBUTIONS 

  4.1.  TIME OF PAYMENT OF UNITS.  The Company will pay to each Director the
value of the Unit or Units, rounded to the nearest whole share of Company common
stock, with respect to which a proper and timely election has been made. Such   
payment shall be made as soon as practicable following the exercise date.       

4.2.  MANNER OF PAYMENT OF UNITS.  Distribution of a Director's benefit 
under Section 4.1 will be made in a single lump sum in the form of whole shares 
of Company common stock rounded to the nearest whole

share. The number of shares to be issued under this Section 4.2 will be based on
the Per Share Value on the exercise date of the Units. For example, if the Per  
Share Value on the date of exercise was $50.00 and the payment amount determined
under Section 3.8 was $367.00, the Director would be entitled to receive seven  
(7) shares of Company stock (367 DIVIDED BY 50 = 7.34). On the other hand, if   
the payment amount determined under Section 3.8 was $380.00, the Director would 
be entitled to receive eight (8) shares of Company stock ($380 DIVIDED BY 50 =  
7.60).                                                                          

4.3.  DISTRIBUTION ON CHANGE OF CONTROL.  Notwithstanding any other Plan
provision to the contrary, each Director will be entitled to receive, within    
ninety (90) days of a Change in Control of the Company, a lump sum payment, in  
cash, of the value of his Units determined under Section 3.8 as of the date of  
the Change in Control of the Company.                                           

4.4.  PAYMENT FOR STOCK.                                                

    (a) Full payment for shares purchased pursuant to the exercise of an
   Option hereunder shall be made at the time the Option is exercised. Payment
may be made by delivering to the Company (i) cash; (ii) Delivered Stock 
 which (A) has been owned by the optionee for more than six (6) months and
   has been paid for, within the meaning of Securities and Exchange Commission
Rule 144 (and, if such stock was purchased from the Company by use of a 
   promissory note, such note has been fully paid with respect to such stock),
or (B) was obtained by the optionee in the public market or other than  
  through the exercise of an Option under this Plan or under any other stock
option plan involving Company stock; (iii) a combination of cash and    
Delivered Stock; or (iv) provided that a public market for the Company's
common stock exists, (A) through a "same day sale" commitment from the  
optionee and a NASD Dealer whereby the Director irrevocably elects to   
  exercise the Option and to sell a portion of the common stock so purchased
 in order to pay the option price, and whereby the NASD Dealer irrevocably
  commits upon receipt of such stock to forward the option price directly to
  the Company; or (B) through a "margin" commitment from the Director and an
  NASD Dealer whereby the Director irrevocably elects to exercise the Option
   and to pledge the stock so purchased to the NASD Dealer in a margin account
as security for a loan from the NASD Dealer in the amount of the option 
  price and whereby the NASD Dealer irrevocably commits upon receipt of such
  stock to forward the option price directly to the Company. Delivered Stock
  shall be valued by the Committee at its Fair Market Value determined as of
    the date of the exercise of the Option. No shares shall be issued until full
    payment for them has been made, and a Director shall have none of the rights
 of a shareholder with respect to any shares until they are issued to him.
Upon payment of the full purchase price, the Company shall issue a      
certificate or certificates to the Director evidencing ownership of the 
shares purchased pursuant to the exercise of the Option which contain(s)
such terms, conditions and provisions as may be required and as are     
consistent with the terms, conditions and provisions of the Plan and the
  grant agreement between the Company and the Director. For purposes of this
   Section 4.4, payment for shares purchased hereunder may be delivered to the
Company through such attestation or certification procedures as may be  
established by the Committee from time to time in its sole discretion.  

(b) For purposes of determining the number of Units which can be
exercised under Section 3.7(b), the number of Options surrendered rather
 than the number of shares actually issued under this Section 4.4 shall be
taken into account.

without the approval of the stockholders of the Company (except as otherwise    
required by applicable law, rule or regulation, including without limitation any
shareholder approval of the safe harbor provisions of Rule 16b-3 promulgated

but may not,

without the consent of the holder of an Option or Unit, make any alteration     
which would adversely affect an Option or Unit previously granted under the     
Plan. However, the Board of Directors may not, without the approval of the      
stockholders of the Company, make any alteration which would (a) increase the   
aggregate number of shares subject to Options and Units under the Plan, except  
as provided in Section 5.3; (b) decrease the minimum option price, except as    
provided in Section 5.3; (c) extend the term of the Plan or change the term     
during which any Option or Unit can be exercised; (d) change the restrictions on
the transferability of Options and Units; (e) change the manner of determining  
the option price, the calculation of unit value or the method of payment of     
Units; (f) change the time(s)at or circumstances under which Options and Units  
may be exercised; (g) change the class of individuals eligible for Options and  
Units; (h) change the number of shares of Company common stock authorized for   
issuance under the Plan; or (i) withdraw administration of the Plan from the    
Committee or Board of Directors.                                                

5.2.  NONTRANSFERABILITY.                                               

     (a) No Option or Unit shall be transferable, except by the Director's
will or the laws of descent and distribution. During the Director's     
lifetime, his Options and Units shall be exercisable (to the extent     
exercisable) only by him. The Options and Units, and any rights and     
  privileges pertaining thereto, shall not be transferred, assigned, pledged
  or hypothecated by the Director in any way, whether by operation of law or
otherwise and shall not be subject to execution, attachment or similar  
process.                                                                

    (b) Notwithstanding the provisions of subsection (a), a Director may
 transfer Options granted under the Plan to: (i) Immediate Family Members;
(ii) a trust or trusts for the exclusive benefit of Immediate Family    
 Members; or (iii) a partnership or limited liability company in which the
optionee and/or the Immediate Family Members are the only equity owners 
   (collectively, "Eligible Transferees"). An Option that is transferred to an
  Immediate Family Member shall not be transferable by such Immediate Family
    Member, except for any transfer by such Immediate Family Member's will or by
    the laws of descent and distribution upon the death of such Immediate Family
Member.                                                                 

 (c) In the event that a Director transfers Options to an Eligible
  Transferee under this Section 5.2, the Options transferred to the Eligible
  Transferee must be exercised by such Eligible Transferee and, in the event
of the death of such Eligible Transferee, by such Eligible Transferee's 
 executor or administrator only in the same manner, to the same extent and
    under the same circumstances (including, without limitation, the time period
    within which the Options must be exercised) as the Director or, in the event
of the Director's death, the executor or administrator of the Director's
   estate, could have exercised such Options. The Director, or in the event of
the Director's death, the Director's estate, shall remain liable for all
federal, state, city and local taxes applicable upon the exercise of an 
Option by an Eligible Transferee.                                       

5.3.  CHANGES IN STOCK.                                                 

      (a) SUBSTITUTION OF STOCK AND ASSUMPTION OF PLAN.  In the event of any
change in the common stock of the Company through stock dividends,      
    split-ups, recapitalization, reclassifications or otherwise, or in the event
 that other stock shall be substituted for the present common stock of the
Company as the result of any merger, consolidation or reorganization or 
 similar transaction which constitutes a Change in Control of the Company,
   then the Committee shall make appropriate adjustment or substitution in the
  (i) aggregate number, price and kind of shares to be distributed under the
  Plan and in the calculation of a Unit's value provided in Section 3.8; and
    (ii) aggregate number, price and kind of shares available under the Plan and
   in the number, price and kind of shares covered under any Options and Units
 granted or to be granted under the Plan. The Committee's determination in
this respect shall be final and conclusive. Provided, however, that the 
Company shall not, and shall not permit its Subsidiaries to, recommend, 
 facilitate or agree or consent to a transaction or series of transactions
 which would result in a Change of Control of the Company unless and until
  the person or persons or entity or entities acquiring or succeeding to the
assets or capital stock of the

Company or any of its Subsidiaries as a result of such transaction or   
transactions agrees to be bound by the terms of the Plan so far as it   
  pertains to Options and Units theretofore granted and agrees to assume and
perform the obligations of the Company and its Successor hereunder (as  
defined in subsection (b)).                                             

    (b) CONVERSION OF STOCK.  In the event of a Change in Control of the
  Company pursuant to which another person or entity acquires control of the
Company (such other person or entity being the "Successor"), the kind of
shares of common stock which shall be subject to the Plan and to each   
    outstanding Option and Unit shall, automatically by virtue of such Change in
  Control of the Company, be converted into and replaced by shares of common
 stock, or such other class of securities having rights and preferences no
   less favorable than common stock of the Successor, and the number of shares
subject to an Option, the calculation of a Unit's value and the purchase
price per share upon exercise of the Option shall be correspondingly    
   adjusted, so that, by virtue of such Change in Control of the Company, each
 Director shall (i) in the case of Options, have the right to purchase (A)
that number of shares of common stock of the Successor which have a Fair
    Market Value equal, as of the date of such Change in Control of the Company,
 to the Fair Market Value, as of the date of such Change in Control of the
    Company, of the shares of common stock of the Company theretofore subject to
    his Option, (B) for a purchase price per share which, when multiplied by the
number of shares of common stock of the Successor subject to the Option,
 shall equal the aggregate exercise price at which the Director could have
acquired all of the shares of common stock of the Company previously    
  optioned to the Director; and (ii) in the case of Units, have the right to
   receive that number of shares of common stock of the Successor which have a
Fair Market Value equal, as of the date of such Change in Control of the
    Company, to the shares of the common stock of the Company to which the Units
relate.                                                                 

  5.4.  USE OF PROCEEDS.  The proceeds received by the Company from the sale
of stock pursuant to the Plan will be used for general corporate purposes.      

5.5.  INFORMATION TO BE FURNISHED BY DIRECTORS.  Directors, or any other
persons entitled to benefits under the Plan, must furnish to the Committee such 
documents, evidence, data or other information as the Committee considers       
necessary or desirable for the purpose of administering the Plan. The benefits  
under the Plan for each Director, and each other person who is entitled to      
benefits hereunder, are to be provided on the condition that he furnish full,   
true and complete data, evidence or other information, and that he will promptly
sign any document reasonably related to the administration of the Plan requested
by the Committee.                                                               

5.6.  EVIDENCE.  Evidence required of anyone under the Plan may be by   
certificate, affidavit, document or other information which the person relying  
thereon considers pertinent and reliable, and signed, made or presented by the  
proper party or parties.                                                        

 5.7.  GENDER AND NUMBER.  When the context admits, words in the masculine
gender shall include the feminine gender, the plural shall include the singular 
and the singular shall include the plural.                                      

    5.8.  ACTION BY COMPANY.  Any action required of or permitted by the Company
under the Plan shall be by resolution of the Committee or by a person or persons
authorized by resolution of the Committee.                                      

   5.9.  CONTROLLING LAWS.  Except to the extent superseded by the laws of the
United States, the laws of Indiana, without regard to the choice of law         
principles thereof, shall be controlling in all matters relating to the Plan.   

   5.10.  MISTAKE OF FACT.  Any mistake of fact or misstatement of facts shall
be corrected when it becomes known and proper adjustment made by reason thereof.

   5.11.  SEVERABILITY.  In the event any provisions of the Plan shall be held
illegal or invalid for any reason, such illegality or invalidity shall not      
affect the remaining parts of the Plan, and the Plan shall be construed and     
enforced as if such illegal or invalid provisions had never been contained in   
the Plan.                                                                       

5.12.  EFFECT OF HEADINGS.  The descriptive headings and sections of the
Plan are inserted for convenience of reference and identification only and do   
not constitute a part of the Plan for purposes of interpretation.               

   5.15.  FUNDING.  Benefits payable under the Plan to any person will be paid
by the Company or its Affiliates from their general assets. Shares of Company   
common stock to be distributed hereunder shall be issued directly by the Company
or acquired by the Company or its Affiliates, on the open market, or a          
combination thereof. Neither the Company nor any of its Affiliates shall be     
required to segregate on their books or otherwise establish any funding         
procedure for any amount to be used for the payment of benefits under the Plan. 
The Company or any of its Affiliates may, however, in their sole discretion, set
funds aside in investments to meet any anticipated obligations under the Plan.  
Any such action or set-aside shall not be deemed to create a trust of any kind  
between the Company or any of its Affiliates and any Director or other person   
entitled to benefits under the Plan or to constitute the funding of any Plan    
benefits. Consequently, any person entitled to a payment under the Plan will    
have no rights greater than the rights of any other unsecured creditor of the   
Company or its Affiliates.                                                      

    5.16.  LIABILITY.  No member of the Board of Directors, the Committee or any
officer or employee of the Company or any of its Affiliates shall be personally 
liable for any action, omission or determination made in good faith in          
connection with the Plan. By participating in the Plan, each Director agrees to 
release and hold harmless the Company, its Affiliates (and their respective     
directors, officers and employees) and the Committee from and against any tax   
liability, including without limitation, interest and penalties, incurred by the
Director in connection with his receipt of Options and Units under the Plan and 
the exercise thereof.                                                           

5.17.  WITHHOLDING.  Each Director shall be solely responsible for (and,
where required by applicable law, the Company will withhold from any amounts    
payable under the Plan) all legally required federal, state, city and local     
taxes. The Committee shall permit a Director to satisfy, in whole or in part,   
any withholding tax obligation which may arise in connection with the exercise  
of an Option or Unit by having the Company retain shares of stock which would   
otherwise be issued in connection with the exercise of the Option or Unit or    
accept delivery from the Director of shares of Company stock which have a Fair  
Market Value, determined as of the date of the delivery of such shares, equal to
the amount of withholding tax to be satisfied by that delivery.

employees, upon whose judgment, initiative and industry the Company and its     
Subsidiaries are largely dependent for the successful conduct and growth of     
their businesses, the opportunity to receive nonqualified stock options         
("Options") and dividend increase units ("Units") in lieu of Eligible           
Compensation (as defined below) thereby encouraging focus on the growth,

(b)  NO CONTRACT OF EMPLOYMENT.  Neither the Plan, nor any Grant
   Agreement executed under the Plan shall constitute a contract of employment
 and participation in the Plan will not give a Participant the right to be

ELIGIBILITY AND VESTING 

  2.1.  ELIGIBILITY.  Participation in the Plan is limited to those officers

 limitations of Article III, for each calendar year during the term of the
 Plan, an officer or employee who has been designated as a Participant may
elect to reduce his Eligible Compensation from the Company and receive  
grants of Options and Units hereunder by delivering a completed

BENEFITS

 3.1.  SHARES COVERED BY THE PLAN.  The stock to be subject to Options and
Units under the Plan shall be shares of authorized common stock of the Company  
and may be unissued shares or reacquired shares (including shares purchased in  
the open market), or a combination of the two, as the Committee may from time to
time determine. Subject to the provisions of Sections 4.4 and 5.3 and the       
provisions of this Section 3.1, the maximum number of shares to be delivered    
upon exercise of all Options and Units granted under the Plan shall not exceed  
Five Hundred Thousand (500,000) shares. If the exercise price of any stock      
option granted under the Plan is satisfied by tendering shares to the Company   
(by either actual delivery or by attestation), only the number of shares issued 
net of the shares tendered shall be deemed delivered for purposes of determining
the maximum number of shares available for delivery under the Plan. Shares      
covered by an Option or Unit that are forfeited due to termination of service or
that remain unpurchased or undistributed upon expiration or termination of the  
Option or Unit, respectively, may be made subject to further Options and Units. 

A. STOCK OPTIONS

    3.2.  GRANT OF OPTIONS.  For each calendar year during the term of the Plan,
each Participant who has made an election under Section 2.2 shall receive one or
more grants of Options for the calendar year to which the Participant's         
Participation Agreement relates. Such grant shall be made by the Committee. The 
number of the Options granted for each dollar of Eligible Compensation deferred 
for such calendar year and the date(s) of grant shall be determined at the sole 
discretion of the Committee, provided that the number of Options granted shall  
equal the number of Units granted under Section 3.6. In the event the           
Participant's employment is terminated for any reason prior to the last day of  
the calendar year during which a Participation Agreement is in effect, the      
Options granted to him for such calendar year that are attributable to the      
deferral of Basic Salary (determined at the sole discretion of the Committee)   
shall be reduced to reflect the amount of Basic Salary which was not payable to 
the Participant due to his termination of employment.                           

   3.3.  EXERCISE OF OPTIONS.  All Options shall vest on the effective date of
the Option grant. However, Options shall not be exercisable until the first     
anniversary of the effective date of the Option grant. An Option must be        
exercised on or before the tenth anniversary of the date on which it was        
granted. If not exercised on or before that date, the Option shall expire. In   
addition, all rights to exercise an Option shall terminate two (2) years after  
the effective date of the Participant's termination of employment with the      
Company and its Subsidiaries, but not later than the date the Option expires    
pursuant to its terms, unless such termination is For Cause. Transfer of        
employment from the Company to a Subsidiary, or vice versa, or from one         
Subsidiary to another, shall not be deemed a termination of employment. The     
Committee shall have the authority to determine in each case whether a leave of 
absence on military or government service shall be deemed a termination of      
employment for purposes of this Section 3.3. If a Participant's employment is   
terminated For Cause, his rights to exercise his Option shall expire on the date
of termination. If a Participant's employment terminates due to Permanent and   
Total Disability or death, the Participant, his guardian, attorney-in-fact or   
personal representative, as the case may be, may exercise his Option subject to 
the limitations of this Plan and the Option grant.                              

  3.4.  OPTION PRICE.  The option price per share of stock under each Option
shall be not less than one hundred percent (100%) of the Fair Market Value of   
the shares as of the date on which the Option is granted.                       

B. DIVIDEND INCREASE UNITS

  3.6.  GRANT OF UNITS.  For each calendar year during the term of the Plan,
each Participant who has made an election under Section 2.2 shall receive one or
more grants of Units for the calendar year to which the Participant's           
Participation Agreement relates. Such grant shall be made by the Committee. The

number of the Units granted for each dollar of Eligible Compensation deferred   
for such calendar year and the date(s) of grant shall be determined at the sole 
discretion of the Committee, provided that the number of Units granted shall    
equal the number of Options granted under Section 3.2. In the event the         
Participant's employment is terminated for any reason prior to the last day of  
the calendar year for which his Participation Agreement is in effect, the number
of Units granted to him for such calendar year that are attributable to the     
deferral of Basic Salary (determined at the sole discretion of the Committee)   
shall be reduced to reflect the amount of Basic Salary which was not payable to 
the Participant due to his termination of employment.                           

 3.7.  EXERCISE OF UNITS.  A Participant may exercise his Units subject to
the following requirements:                                                     

       (a)  TIMING OF EXERCISE.  All Units shall vest on the effective date of
the Unit grant. However, a Unit shall not be exercisable until the first
anniversary of the effective date of the Unit grant. A Unit must be     
exercised on or before the tenth anniversary of the date on which it was
   granted. If not exercised on or before that date, the Unit shall expire. In
   addition, all rights to exercise a Unit shall terminate two (2) years after
  the effective date of the Participant's termination of employment with the
  Company and its Subsidiaries, but not later than the date the Unit expires
pursuant to its terms, unless such termination is For Cause. Transfer of
employment from the Company to a Subsidiary, or vice versa, or from one 
   Subsidiary to another, shall not be deemed a termination of employment. The
    Committee shall have the authority to determine in each case whether a leave
  of absence on military or government service shall be deemed a termination
of employment for purposes of this Section 3.7(a). If a Participant's   
  employment is terminated For Cause, his rights to exercise his Units shall
   expire on the date of termination. If a Participant's employment terminates
due to Permanent and Total Disability or death, the Participant, his    
  guardian, attorney-in-fact or personal representative, as the case may be,
    may exercise his Units subject to the limitations of this Plan and the Grant
Agreement.                                                              

     (b)  PRIOR EXERCISE OF STOCK OPTIONS.  Units may be exercised only to
the extent that the same or a greater number of Options have been       
    surrendered by the Participant through the exercise of Options granted under
    the Plan on the same date on which the Units were granted. Such exercise may
have been prior to or simultaneous with the exercise of such Units. For 
 example, if a Participant was granted an Option under the Plan to acquire
  Two Thousand Five Hundred (2,500) shares of the Company's stock and on the
  same date he was granted Two Thousand Five Hundred (2,500) Units under the
    Plan, the Participant may not exercise the Two Thousand Five Hundred (2,500)
 Units granted hereunder until he has exercised at least Two Thousand Five
Hundred (2,500) Options under that stock option grant. Thus, if the     
    Participant has exercised (or is simultaneously exercising with his exercise
    of the Units) One Thousand (1,000) Options under that stock option grant, he
 may at any time on or after the date of such exercise, exercise up to One
Thousand (1,000) Units granted on the same date as the date such Options
   were granted, as long as all the other Plan conditions and limitations have
 been satisfied with respect to such exercise. The shares of Company stock
    acquired by the exercise of an Option on a date other than the date on which
  the Units were granted may not be used as a basis for the exercise of such
Units.                                                                  

(c)  PRIOR NOTICE OF EXERCISE.  The Participant must notify the 
 Committee of his intent to exercise a Unit by completing an election form
authorized by the Committee and filing such form with the Committee.    

    3.8.  CALCULATION OF UNIT VALUE AT TIME OF PAYMENT.  Upon the exercise date,
the Unit or Units being exercised will be valued for all purposes under the Plan
in accordance with the following formula. First, the Per Share Value of a share 
of the Company's common stock, as of the effective date on which the Unit was   
granted, will be determined. Second, the quarterly cash dividend rate per share 
of the Company's common stock most recently declared prior to the effective date
of the grant will be determined and annualized (multiplied by four). Third, that
annualized cash dividend will be divided by the Per Share Value on the effective
date of the grant to set the grant date dividend yield. Fourth, the quarterly   
cash dividend rate per

share of the Company's common stock which was most recently declared on or      
before the exercise date will be determined and annualized (multiplied by four).
Fifth, the annualized cash dividend on the effective date of the grant (as      
determined under the second step) will be subtracted from the annualized        
dividend on the exercise date (as determined under the fourth step) to determine
the increase in the annualized cash dividend. Sixth, the amount of the increase 
(as determined under the fifth step) will be divided by the grant date dividend 
yield (as determined under the third step) to establish the Unit's value on the 
exercise date. For all purposes of this Plan, if there is no Per Share Value for
Company stock on the date on which an event which requires the stock to be      
valued, the per share value shall be the Per Share Value for Company stock on   
the trading date immediately preceding the date on which the stock is required  
to be valued.                                                                   

For example, if the Per Share Value of a share of Company stock on the  
effective date of a Unit's grant was $30.00, the quarterly dividend rate on the 
date of grant was $0.49 and the quarterly dividend rate on the date of exercise 
was $0.55, then the Unit's value at exercise would be $3.67, determined under   
the six steps in the preceding paragraph as follows:                            

                                                                [Download Table]
                                                                                 
(1)  $30.00   [NYSE Closing Price on Date of Grant]                              
(2)  $1.96    [$0.49 (Company's Quarterly Cash Dividend on Date of Grant) X 4]   
(3)  6.5333%  [(2)  DIVIDED BY (1)]                                              
(4)  $2.20    [$0.55 (Company's Quarterly Cash Dividend on Date of Exercise) X 4]
(5)  $0.24    [$2.20-$1.96 = Increase in Annualized Cash Dividend]               
(6)  $3.67    [(5)  DIVIDED BY (3)]                                              

If the Participant had been granted one hundred (100) Units and he exercised all
of those Units, he would be entitled to receive whole shares of Company common  
stock with a value of $367 based on the Per Share Value on the date of exercise.
(The number of shares to be distributed is described under Section 4.2).        

ARTICLE IV
DISTRIBUTIONS 

 4.1.  TIME OF PAYMENT OF UNITS.  The Company will pay to each Participant
the value of the Unit or Units, rounded to the nearest whole share of Company   
common stock, with respect to which a proper and timely election has been made. 
Such payment shall be made as soon as practicable following the exercise date.  

  4.2.  MANNER OF PAYMENT OF UNITS.  Distribution of a Participant's benefit
under Section 4.1 will be made in a single lump sum in the form of whole shares 
of Company common stock rounded to the nearest whole share. The number of shares
to be issued under this Section 4.2 will be based on the Per Share Value on the 
exercise date of the Units. For example, if the Per Share Value on the date of  
exercise was $50.00 and the payment amount determined under Section 3.8 was     
$367.00, the Participant would be entitled to receive seven (7) shares of       
Company stock (367 DIVIDED BY 50 = 7.34). On the other hand, if the payment     
amount determined under Section 3.8 was $380.00, the Participant would be       
entitled to receive eight (8) shares of Company stock ($380 DIVIDED BY 50 =     
7.60).                                                                          

4.3.  DISTRIBUTION ON CHANGE OF CONTROL.  Notwithstanding any other Plan
provision to the contrary, each Participant will be entitled to receive, within 
ninety (90) days of a Change in Control of the Company, a lump sum payment, in  
cash, of the value of his Units determined under Section 3.8 as of the date of  
the Change in Control of the Company.                                           

4.4.  PAYMENT FOR STOCK.                                                

    (a) Full payment for shares purchased pursuant to the exercise of an
   Option hereunder shall be made at the time the Option is exercised. Payment
may be made by delivering to the Company (i) cash; (ii) Delivered Stock 
which (A) has been owned by the Participant for more than six

   (6) months and has been paid for, within the meaning of Securities Exchange
 Commission Rule 144 (and, if such stock was purchased from the Company by
    use of a promissory note, such note has been fully paid with respect to such
    stock), or (B) was obtained by the Participant in the public market or other
 than through the exercise of an Option under this Plan or under any other
  stock option plan involving Company stock; (iii) a combination of cash and
Delivered Stock; or (iv) provided that a public market for the Company's
common stock exists, (A) through a "same day sale" commitment from the  
   Participant and a NASD Dealer whereby the Participant irrevocably elects to
  exercise the Option and to sell a portion of the common stock so purchased
 in order to pay the option price, and whereby the NASD Dealer irrevocably
  commits upon receipt of such stock to forward the option price directly to
  the Company; or (B) through a "margin" commitment from the Participant and
 an NASD Dealer whereby the Participant irrevocably elects to exercise the
  Option and to pledge the stock so purchased to the NASD Dealer in a margin
account as security for a loan from the NASD Dealer in the amount of the
    option price and whereby the NASD Dealer irrevocably commits upon receipt of
 such stock to forward the option price directly to the Company. Delivered
  Stock shall be valued by the Committee at its Fair Market Value determined
as of the date of the exercise of the Option. No shares shall be issued 
    until full payment for them has been made, and a Participant shall have none
of the rights of a shareholder with respect to any shares until they are
 issued to him. Upon payment of the full purchase price, the Company shall
   issue a certificate or certificates to the Participant evidencing ownership
of the shares purchased pursuant to the exercise of the Option which    
  contain(s) such terms, conditions and provisions as may be required and as
    are consistent with the terms, conditions and provisions of the Plan and the
grant agreement. For purposes of this Section 4.4, payment for shares   
    purchased hereunder may be delivered to the Company through such attestation
    or certification procedures as may be established by the Committee from time
to time in its sole discretion.                                         

(b) For purposes of determining the number of Units which can be
    exercised under Section 3.7, the number of Options exercised rather than the
   number of shares actually issued under this Section 4.4 shall be taken into
account.                                                                

ARTICLE V 
PLAN ADMINISTRATION AND INTERPRETATION

5.1  AMENDMENT OR TERMINATION.  The Board of Directors may, at any time,
without the approval of the stockholders of the Company (except as otherwise    
required by applicable law, rule or regulation, including without limitation any
shareholder approval of the safe harbor provisions of Rule 16b-3 promulgated    
under the Exchange Act) alter, amend, modify, suspend or discontinue the Plan,  
but may not, without the consent of the holder of an Option or Unit, make any   
alteration which would adversely affect an Option or Unit previously granted    
under the Plan. However, the Board of Directors may not, without the approval of
the stockholders of the Company, make any alteration which would (a) change the 
number of shares of Company common stock authorized for issuance under the Plan,
except as provided in Section 5.3; (b) decrease the minimum option price, except
as provided in Section 5.3; (c) extend the term of the Plan or change the term  
during which any Option or Unit can be exercised; (d) change the class of       
individuals eligible for Options and Units; or (e) withdraw administration of   
the Plan from the Committee or Board of Directors.                              

5.2.  NONTRANSFERABILITY.                                               

        (a) No Option or Unit shall be transferable, except by the Participant's
will or the laws of descent and distribution. During the Participant's  
lifetime, his Options and Units shall be exercisable (to the extent     
exercisable) only by him. The Options and Units, and any rights and     
  privileges pertaining thereto, shall not be transferred, assigned, pledged
  or hypothecated by the Participant in any way, whether by operation of law
 or otherwise and shall not be subject to execution, attachment or similar
process.

       (b) Notwithstanding the provisions of subsection (a), a Participant may
 transfer Options granted under the Plan to: (i) Immediate Family Members;
(ii) a trust or trusts for the exclusive benefit of Immediate Family    
 Members; or (iii) a partnership or limited liability company in which the
  Participant and/or the Immediate Family Members are the only equity owners
   (collectively, "Eligible Transferees"). An Option that is transferred to an
  Immediate Family Member shall not be transferable by such Immediate Family
    Member, except for any transfer by such Immediate Family Member's will or by
    the laws of descent and distribution upon the death of such Immediate Family
Member.                                                                 

    (c) In the event that a Participant transfers Options to an Eligible
  Transferee under this Section 5.2, the Options transferred to the Eligible
  Transferee must be exercised by such Eligible Transferee and, in the event
of the death of such Eligible Transferee, by such Eligible Transferee's 
 executor or administrator only in the same manner, to the same extent and
    under the same circumstances (including, without limitation, the time period
 within which the Options must be exercised) as the Participant or, in the
event of the Participant's death, the executor or administrator of the  
    Participant's estate, could have exercised such Options. The Participant, or
in the event of the Participant's death, the Participant's estate, shall
  remain liable for all federal, state, city and local taxes applicable upon
the exercise of an Option by an Eligible Transferee.                    

5.3.  CHANGES IN STOCK.                                                 

       (a)  SUBSTITUTION OF STOCK AND ASSUMPTION OF PLAN.  In the event of any
change in the common stock of the Company through stock dividends,      
    split-ups, recapitalization, reclassifications or otherwise, or in the event
 that other stock shall be substituted for the present common stock of the
Company as the result of any merger, consolidation or reorganization or 
 similar transaction which constitutes a Change in Control of the Company,
   then the Committee shall make appropriate adjustment or substitution in the
  (i) aggregate number, price and kind of shares to be distributed under the
  Plan and in the calculation of a Unit's value provided in Section 3.8; and
    (ii) aggregate number, price and kind of shares available under the Plan and
   in the number, price and kind of shares covered under any Options and Units
 granted or to be granted under the Plan. The Committee's determination in
this respect shall be final and conclusive. Provided, however, that the 
Company shall not, and shall not permit its Subsidiaries to, recommend, 
 facilitate or agree or consent to a transaction or series of transactions
 which would result in a Change of Control of the Company unless and until
  the person or persons or entity or entities acquiring or succeeding to the
assets or capital stock of the Company or any of its Subsidiaries as a  
  result of such transaction or transactions agrees to be bound by the terms
  of the Plan so far as it pertains to Options and Units theretofore granted
and agrees to assume and perform the obligations of the Company and its 
Successor hereunder (as defined in subsection (b)).                     

     (b)  CONVERSION OF STOCK.  In the event of a Change in Control of the
  Company pursuant to which another person or entity acquires control of the
Company (such other person or entity being the "Successor"), the kind of
shares of common stock which shall be subject to the Plan and to each   
    outstanding Option and Unit shall, automatically by virtue of such Change in
  Control of the Company, be converted into and replaced by shares of common
 stock, or such other class of securities having rights and preferences no
   less favorable than common stock of the Successor, and the number of shares
subject to an Option, the calculation of a Unit's value and the purchase
price per share upon exercise of the Option shall be correspondingly    
   adjusted, so that, by virtue of such Change in Control of the Company, each
    shall (i) in the case of Options, have the right to purchase (A) that number
 of shares of common stock of the Successor which have a Fair Market Value
   equal, as of the date of such Change in Control of the Company, to the Fair
 Market Value, as of the date of such Change in Control of the Company, of
    the shares of common stock of the Company theretofore subject to his Option,
  (B) for a purchase price per share which, when multiplied by the number of
  shares of common stock of the Successor subject to the Option, shall equal
 the aggregate exercise price at which the Participant could have acquired
all of the shares of common stock of the Company previously

  optioned to the Participant; and (ii) in the case of Units, have the right
    to receive that number of shares of common stock of the Successor which have
  a Fair Market Value equal, as of the date of such Change in Control of the
    Company, to the shares of the common stock of the Company to which the Units
relate.                                                                 

  5.4.  USE OF PROCEEDS.  The proceeds received by the Company from the sale
of stock pursuant to the Plan will be used for general corporate purposes.      

5.5.  INFORMATION TO BE FURNISHED BY PARTICIPANTS.  Participants, or any
other persons entitled to benefits under the Plan, must furnish to the Committee
such documents, evidence, data or other information as the Committee considers  
necessary or desirable for the purpose of administering the Plan. The benefits  
under the Plan for each Participant, and each other person who is entitled to   
benefits hereunder, are to be provided on the condition that he furnish full,   
true and complete data, evidence or other information, and that he will promptly
sign any document reasonably related to the administration of the Plan requested
by the Committee.                                                               

5.6.  EVIDENCE.  Evidence required of anyone under the Plan may be by   
certificate, affidavit, document or other information which the person relying  
thereon considers pertinent and reliable, and signed, made or presented by the  
proper party or parties.                                                        

 5.7.  GENDER AND NUMBER.  When the context admits, words in the masculine
gender shall include the feminine gender, the plural shall include the singular 
and the singular shall include the plural.                                      

    5.8.  ACTION BY COMPANY.  Any action required of or permitted by the Company
under the Plan shall be by resolution of the Committee or by a person or persons
authorized by resolution of the Committee.                                      

   5.9.  CONTROLLING LAWS.  Except to the extent superseded by the laws of the
United States, the laws of Indiana, without regard to the choice of law         
principles thereof, shall be controlling in all matters relating to the Plan.   

   5.10.  MISTAKE OF FACT.  Any mistake of fact or misstatement of facts shall
be corrected when it becomes known and proper adjustment made by reason thereof.

   5.11.  SEVERABILITY.  In the event any provisions of the Plan shall be held
illegal or invalid for any reason, such illegality or invalidity shall not      
affect the remaining parts of the Plan, and the Plan shall be construed and     
enforced as if such illegal or invalid provisions had never been contained in   
the Plan.                                                                       

5.12.  EFFECT OF HEADINGS.  The descriptive headings and sections of the
Plan are inserted for convenience of reference and identification only and do   
not constitute a part of the Plan for purposes of interpretation.               

   5.13.  FUNDING.  Benefits payable under the Plan to any person will be paid
by the Company or its Subsidiaries from their general assets. Shares of Company 
common stock to be distributed hereunder shall be issued directly by the Company
or acquired by the Company or its Subsidiaries, on the open market, or a        
combination thereof. Neither the Company nor any of its Subsidiaries shall be   
required to segregate on their books or otherwise establish any funding         
procedure for any amount to be used for the payment of benefits under the Plan. 
The Company or any of its Subsidiaries may, however, in their sole discretion,  
set funds aside in investments to meet any anticipated obligations under the    
Plan. Any such action or set-aside shall not be deemed to create a trust of any 
kind between the Company or any of its Subsidiaries and any Participant or other
person entitled to benefits under the Plan or to constitute the funding of any  
Plan benefits. Consequently, any person entitled to a payment under the Plan    
will have no rights greater than the rights of any other unsecured creditor of  
the Company or its Subsidiaries.                                                

    5.14.  LIABILITY.  No member of the Board of Directors, the Committee or any
officer or employee of the Company or any of its Subsidiaries shall be          
personally liable for any action, omission or determination made in good faith  
in connection with the Plan. By participating in the Plan, each Participant     
agrees to release and hold harmless the Company, its Subsidiaries (and their    
respective directors, officers and

employees) and the Committee from and against any tax liability, including      
without limitation, interest and penalties, incurred by the Participant in      
connection with his receipt of Options and Units under the Plan and the exercise
thereof.                                                                        

   5.15.  WITHHOLDING.  Each Participant shall be solely responsible for (and,
where required by applicable law, the Company will withhold from any amounts    
payable under the Plan) all legally required federal, state, city and local     
taxes. The Committee shall permit a Participant to satisfy, in whole or in part,
any withholding tax obligation which may arise in connection with the exercise  
of an Option or Unit by having the Company retain shares of stock which would   
otherwise be issued in connection with the exercise of the Option or Unit or    
accept delivery from the Participant of shares of Company stock which have a    
Fair Market Value, determined as of the date of the delivery of such shares,    
equal to the amount of withholding tax to be satisfied by that delivery.

AMENDMENT ONE TO THE 1996 
DIRECTORS' STOCK PAYMENT PLAN OF

   This Amendment One to the 1996 Directors' Stock Payment Plan of Duke Realty
Investments, Inc. ("Plan") is hereby adopted this 12th day of March, 1999 by    
Duke Realty Investments, Inc. ("Company");                                      

W I T N E S S E T H:

 WHEREAS, the Company adopted the Plan for the purposes set forth therein;
and                                                                             

WHEREAS, pursuant to Section 7 of the Plan, the Company has reserved the
right to amend the Plan with respect to certain matters, by action of the Board 
of Directors of Duke Realty Investments, Inc. ("Board"); and                    

WHEREAS, the Plan currently provides that each Plan participant will be 
entitled to receive one hundred fifty (150) shares of common stock of the       
Company for each full calendar quarter during which he is actively serving as a 
Director of the Company; and                                                    

    WHEREAS, the Plan currently provides that the maximum number of shares to be
distributed under the Plan shall not exceed twenty thousand (20,000) shares; and

WHEREAS, the Board approved a two (2) for one (1) stock split of the    
Company's common stock effective as of August 25, 1997, with respect to all     
shareholders of record as of August 18, 1997; and                               

  WHEREAS, as a result of the two (2) for one (1) stock split, the number of
shares of common stock to which each Director is entitled for each calendar     
quarter was increased to three hundred (300) and the maximum number of shares to
be distributed under the Plan was increased to forty thousand (40,000);         

   WHEREAS, the Board has approved an increase in the maximum number of shares
to be distributed under the Plan from 40,000 shares to 140,000 shares; and      

WHEREAS, the Board has approved and authorized this Amendment One;      

NOW, THEREFORE, pursuant to the authority reserved to the Company under 
Sections 5 and 7 of the Plan, the Plan is hereby amended by substituting the    
following for Sections 4 and 6 of the Plan:                                     

 "4.  SHARES COVERED BY THE PLAN.  The stock to be subject to distribution
under the Plan shall be shares of authorized common stock of the Company and may
be unissued shares or reacquired shares (including shares purchased in the open 
market), or a combination of the two, as the Committee may from time to time    
determine. Provided, however, subject to the provisions of Section 5 and the    
provisions of this Section 4, the maximum number of shares to be distributed    
under the Plan shall not exceed One Hundred Forty Thousand (140,000) shares."   

    "6.  PLAN BENEFITS.  Each Plan participant will be entitled to receive three
hundred (300) shares of common stock of the Company for each full calendar      
quarter during which he is actively serving as a Director of the Company. In the
event a participant is a Director for less than a full calendar quarter, the    
number of shares he shall be entitled to receive hereunder shall be based on a  
fraction the numerator of which is the number of days in the calendar quarter   
during which he serves as a Director and the denominator of which is ninety     
(90). Distribution of shares shall be made effective as of the first day of the 
calendar quarter (January 1, April 1, July 1 and October 1) immediately         
following the calendar quarter to which the Director's service relates.         
Distribution of those shares shall be made on, or as soon as practicable        
following, that date."

1996 DIRECTORS' STOCK PAYMENT PLAN
OF
DUKE REALTY INVESTMENTS, INC. 

1.  PURPOSE.  The 1996 Directors' Stock Payment Plan of Duke Realty     
Investments, Inc. (the "Plan") is designed to promote the interests of Duke     
Realty Investments, Inc. (the "Company") and its Subsidiaries by increasing the 
proprietary interest in the Company of the members of the Company's Board of    
Directors (the "Board"). For purposes of the Plan, "Subsidiary" or              
"Subsidiaries" means a corporation, partnership or limited liability company, a 
majority of the outstanding voting stock, general partnership interests or      
membership interests, as the case may be, of which is owned or controlled,      
directly or indirectly, by the Company or by one or more other Subsidiaries of  
the Company. For the purposes of this definition, "voting stock" means stock    
having voting power for the election of directors, or trustees, as the case may 
be, whether at all times or only so long as no senior class of stock has such   
voting power by reason of any contingency.                                      

2.  ADMINISTRATION.  The Plan will be administered by the Compensation  
Committee of the Board (the "Committee"). The Committee, from time to time, may 
adopt any rule or procedure it deems necessary or desirable for the proper and  
efficient administration of the Plan, provided it is consistent with the terms  
of the Plan. The decision of a majority of the Committee members shall          
constitute the decision of the Committee. The Committee's determinations and    
interpretations with respect to the Plan shall be final and binding on all      
parties. Any notice or document required to be given to or filed with the       
Committee will be properly given or filed if delivered or mailed by certified   
mail, postage prepaid, to the Committee at 8888 Keystone Crossing, Suite 1200,  
Indianapolis, Indiana 46240-2182. Notwithstanding any Plan provision to the     
contrary, the Plan is intended to meet the requirements of Rule 16b-3(c)(2)(ii) 
adopted under the Securities Exchange Act of 1934, as amended (or its successor)
("Act"), and accordingly is intended to be self-governing. To this end, the Plan
requires no discretionary action by any administrative body with regard to any  
transaction hereunder. To the extent, if any, that any questions of             
interpretation arise, such questions shall be resolved by the Committee.        
Transactions under the Plan are intended to comply with all applicable          
conditions of Rule 16b-3 under the Securities Exchange Act of 1934 (or its      
successors). To the extent any provision of this Plan or any action by the      
Committee or the Board fails to so comply, it shall be deemed null and void to  
the extent permitted by law and deemed advisable by the Committee.              

3.  ELIGIBILITY.  Subject to the terms and conditions of the Plan, each 
member of the Board, excluding those directors who are also employees of the    
Company or a Subsidiary (a "Director"), shall receive shares of the Company's   
common stock under the Plan as described in Section 6. A Director shall cease to
be a Plan participant on the date he ceases to be a Director for any reason.    

4.  SHARES COVERED BY THE PLAN.  The stock to be subject to distribution
under the Plan shall be shares of authorized common stock of the Company and may
be unissued shares or reacquired shares (including shares purchased in the open 
market), or a combination of the two, as the Committee may from time to time    
determine. Provided, however, subject to the provisions of Section 5 and the    
provisions of this Section 4, the maximum number of shares to be distributed    
under the Plan shall not exceed Twenty Thousand (20,000) shares.                

5.  ADJUSTMENTS.  If the outstanding shares of stock of the class then  
subject to the Plan are increased or decreased, or are changed into or exchanged
for a different number or kind of shares or securities as a result of one (1) or
more reorganizations, recapitalizations, stock splits, reverse stock splits,    
stock dividends, spin-offs and the like, appropriate adjustments shall be made  
in the number and/or type of shares or securities for which awards shall        
thereafter be granted under the Plan.                                           

 6.  PLAN BENEFITS.  Each Plan participant will be entitled to receive one
hundred fifty (150) shares of common stock of the Company for each full calendar
quarter during which he is actively serving as a

Director of the Company. In the event a participant is a Director for less than 
a full calendar quarter, the number of shares he shall be entitled to receive   
hereunder shall be based on a fraction the numerator of which is the number of  
days in the calendar quarter during which he serves as a Director and the       
denominator of which is ninety (90). Distribution of shares shall be made       
effective as of the first day of the calendar quarter (January 1, April 1, July 
1 and October 1) immediately following the calendar quarter to which the        
Director's service relates. Distribution of those shares shall be made on, or as
soon as practicable following, that date.                                       

 7.  AMENDMENT AND DISCONTINUANCE.  The Board or the Committee may, at any
time, alter, amend, suspend or discontinue the Plan, provided that (i)          
shareholder approval shall be obtained to the extent required to comply with    
Rule 16b-3 or any successor exemptive rule under the Act, and (ii) the          
provisions of the Plan which designate the individuals eligible to participate  
in the Plan and specifying the amount and timing of grants under the Plan shall 
not be amended more than once every six (6) months, other than to comply with   
amendments to the Internal Revenue Code or the rules and regulations promulgated
thereunder.                                                                     

 8.  LIABILITY.  No member of the Board or the Committee or any officer or
employee of the Company or its Subsidiaries shall be personally liable for any

INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.                             

Section eight of Chapter 37 of the Indiana Business Corporation Law (the
"IBCL") empowers a corporation to indemnify any director, or former director,   
who was, is or is threatened to be made a party to any threatened, pending or   
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative and whether formal or informal, against judgments, settlements,   
penalties, fines or reasonable expenses incurred with respect to such action,   
suit or proceeding, provided that such director acted in good faith and in a    
manner reasonably believed to be in or not opposed to the best interests of the 
corporation, and, with respect to any criminal proceeding, provided that such   
director or officer had reasonable cause to believe his or her conduct was      
lawful or had no reasonable cause to believe his or her conduct was unlawful.   

Section 13 of Chapter 37 of the IBCL empowers a corporation to indemnify
officers of a corporation, whether or not a director, to the same extent as to a
director.                                                                       

Chapter 37 of the IBCL further provides that to the extent a present or 
former director or officer of a corporation has been successful in the defense  
of any action, suit or proceeding referred to in Chapter 37, he or she shall be 
indemnified, against reasonable expenses (including counsel fees) incurred by   
him or her in connection therewith; that indemnification provided for in Chapter
37 shall not be deemed exclusive of any other rights to which the indemnified   
party may be entitled; and that the corporation shall have power to purchase and
maintain insurance on behalf of a director or officer of the corporation against
any liability asserted against him or her or incurred by him or her in any such 
capacity or arising out of his or her status as such whether or not the         
corporation would have the power to indemnify him or her against such           
liabilities under Section 8 or 9 of Chapter 37.                                 

  Article XIII of the Amended and Restated Articles of Incorporation of Duke
Realty Investments, Inc. provides that Duke shall indemnify to the fullest      
extent permitted by the IBCL any and all of its directors and officers, or      
former directors and officers, or any person who may have served at Duke's      
request as a director or officer of another corporation, partnership, limited   
liability company, joint venture, trust or other entity or enterprise.          

  Article XIII of the Amended and Restated Articles of Incorporation of Duke
Realty Investments, Inc. provides that, to the fullest extent permitted by the  
IBCL, a director or former director of Duke shall not be personally liable to   
Duke or its stockholders for monetary damages for breach of fiduciary duty as a 
director except for liability for breach of the director's duty of loyalty, acts
or omissions not in good faith or which involve intentional misconduct or a     
knowing violation of law, impermissible distributions, or transactions from     
which the director derived an improper personal benefit.                        

 Duke may maintain liability insurance insuring its officers and directors
against liabilities that they may incur in such capacities, whether or not Duke 
would have the power to indemnify such director or officer against such         
liability under the IBCL.

(a) The undersigned registrant hereby undertakes:                       

       (1) To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:  

         (i) to include any prospectus required by Section 10(a)(3) of the
Securities Act of 1933;                         

           (ii) to reflect in the prospectus any facts or events arising after
               the effective date of the registration statement (or the most
                 recent post-effective amendment thereof) which, individually or
         in the aggregate, represent a fundamental change in the
      information set forth in the registration statement.
            Notwithstanding the foregoing, any increase or decrease in
            volume of securities offered (if the total dollar value of
                securities offered would not exceed that which was registered)
             and any deviation from the low or high end of the estimated
        maximum offering range may be reflected in the form of
              prospectus filed with the Commission pursuant to Rule 424(b)
                 if, in the aggregate, the changes in volume and price represent
         no more than 20 percent change in the maximum aggregate
              offering price set forth in the "Calculation of Registration
         Fee" table in the effective registration statement; and

           (iii) to include any material information with respect to the plan of
           distribution not previously disclosed in the registration
             statement or any material change to such information in the
registration statement.                       

(2) That, for the purpose of determining any liability under the  
         Securities Act of 1933, each such post-effective amendment shall be
          deemed to be a new registration statement relating to the securities
       offered therein, and the offering of such securities at that time
   shall be deemed to be the initial bona fide offering thereof.

    (3) To remove from registration by means of a post-effective amendment
       any of the securities being registered which remain unsold at the
termination of the offering.                              

(b) The undersigned Registrant hereby undertakes that, for purposes of  
determining any liability under the Securities Act of 1933, each filing of the  
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the    
Securities Exchange Act of 1934 that is incorporated by reference in the        
registration statement shall be deemed to be a new registration statement       
relating to the securities offered therein, and the offering of such securities 
at that time shall be deemed to be the initial bona fide offering thereof.      

  (c) The undersigned Registrant hereby undertakes to deliver or cause to be
delivered with the prospectus, to each person to whom the prospectus is sent or 
given, the latest annual report to security holders that is incorporated by     
reference in the prospectus and furnishes pursuant to and meeting the           
requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of   
1934; and, where interim financial information required to be presented by      
Article 3 of Regulation S-X are not set forth in the prospectus, to deliver, or 
cause to be delivered to each person to whom the prospectus is sent or given,   
the

latest quarterly report that is specifically incorporated by reference in the   
prospectus to provide such interim financial information.                       

   (d) (1) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or     
party who is deemed to be an underwriter within the meaning of Rule 145(c), the 
issuer undertakes that such reoffering prospectus will contain the information  
called for by the applicable registration form with respect to reofferings by   
persons who may be deemed underwriters, in addition to the information called   
for by the other items of the applicable form.                                  

      (2) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (1) immediately preceding or (ii) that purports to meet   
the requirements of Section 10(a)(3) of the Securities Act and is used in       
connection with an offering of securities subject to Rule 415, will be filed as 
a part of an amendment to the Registration Statement and will not be used until 
such amendment is effective, and that, for purpose of determining any liability 
under the Securities Act, each such post-effective amendment shall be deemed to 
be a new registration statement relating to the securities offered therein, and 
the offering of such securities at that time shall be deemed to be the initial  
bona fide offering thereof.                                                     

   (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of  
the registrant pursuant to the foregoing provisions, or otherwise, the          
registrant has been advised that in the opinion of the Securities and Exchange  
Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification 
against such liabilities (other than the payment by the registrant of expenses  
incurred or aid by a director, officer or controlling person of the registrant  
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being 
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate     
jurisdiction the question whether such indemnification by it is against public  
policy as expressed in the Act and will be governed by the final adjudication of
such issue.                                                                     

   (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to   
Items 4, 10(b), 11, or 13 of this form, within one business day of receipt of   
such request, and to send the incorporated documents by first class mail or     
other equally prompt means. This includes information contained in documents    
filed subsequent to the effective date of the registration statement through the
date of responding to this request.                                             

(g) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the      
company being acquired involved therein, that was not the subject of and        
included in the registration statement when it became effective.
