The Option may be exercised by Optionee, in whole or in part, from time to time, during the Option Term (as defined below) only in accordance with the following conditions and limitations:

Except as provided in Sections 5 and 7 hereof, Optionee must, at any time the Option becomes exercisable and at any time the Option is exercised, have been continuously in the employment of the Company since the date hereof, unless otherwise determined by the Compensation Committee of the Board of Directors administering the Plan (the “Committee”).  Leave of absence for periods and purposes conforming to the personnel policies of the Company and approved by the Committee shall not be deemed terminations of employment or interruptions of continuous service.

(i)  Subject to Sections 5 and 7 hereof and subsection (ii) below, at any time on and after the dates indicated in column (1), Optionee may purchase such whole number of shares of Common Stock which, when added to all shares theretofore purchased under the Option, does not exceed the total number of shares subject to the Option multiplied by the percentage indicated in column (2) opposite such respective date, as follows:

No fractional shares may be purchased at any time.  

Subject to the limitations herein set forth, the Option may be exercised by delivery of notice to the Company, in such form as the Company determines, specifying the number of shares of Common Stock to be purchased and accompanied by payment in full of the option price (or arrangement made for such payment to the Company's satisfaction) for the number of shares so purchased.  No shares of Common Stock may be purchased under the Option unless Optionee (or in the event of Optionee's death, Optionee's executor, administrator or personal representative or Optionee's beneficiary designated pursuant to the Beneficiary Designation Form on file with the Company (herein called a "Beneficiary")) shall pay to the Company such amount as the Company is advised it is required under applicable federal, state, local or other tax laws to withhold and pay over to governmental taxing authorities by reason of the purchase of shares of Common Stock pursuant to the Option.  

Upon exercise of the Option in whole or in part pursuant to Section 2 hereof, the Company shall deliver or cause to be delivered a certificate (or other evidence of ownership) representing the number of shares specified against payment therefore and shall pay all original issue or transfer taxes and all other fees and expenses incident to such delivery.

Optionee shall be entitled to the privileges of ownership with respect to shares subject to the Option only with respect to shares purchased upon exercise of all or part of the Option and as to which Optionee becomes a stockholder of record.

(a)  If Optionee ceases to be employed by the Company by reason of death or Disability (as defined in the Company’s long-term disability policy as in effect at the time of the Optionee’s disability), then from and after the date of death or such Disability the Option shall be exercisable by Optionee, the executor, administrator, personal representative or Beneficiary of Optionee during the 1-year period commencing on the date of Optionee's death or Disability, but only during the Option Term, with respect to all of the shares of Common Stock subject to the Option.

The Option may not be transferred by Optionee other than by will, the laws of descent and distribution or pursuant to the beneficiary designation procedures approved by the Company or as otherwise set forth in an amendment to this Agreement.  The Option is exercisable only by Optionee or Optionee's guardian, personal representative or similar person or by a permitted transferee.  Except as permitted by the foregoing, the Option may not be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process.  Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of the Option, the Option and all rights hereunder shall immediately become null and void.  

In the event of the death of Optionee (a) during the one-year period commencing on the effective date of Optionee's cessation of employment by reason of Disability, or (b) during the 90-day period commencing on the effective date of Optionee's cessation of employment for reason other than retirement under Section 5(b) or (c), or Disability, the Option may be exercised by the executor, administrator, personal representative or Beneficiary of Optionee during the Option Term remaining, and only to the extent Optionee was entitled to exercise the Option on the date of Optionee's death.

In the event of any stock split, stock dividend, recapitalization, reorganization, merger, consolidation, combination, exchange of shares, liquidation, spin-off or other similar change in capitalization or event, or any distribution to holders of Common Stock other than a regular cash dividend, the number and class of securities subject to the Option and the purchase price per security shall be appropriately adjusted by the Committee without an increase in the aggregate purchase price, other than an increase resulting from rounding.  If any adjustment would result in a fractional security being subject to the Option, the Company shall pay Optionee, in connection with the first exercise of the Option, in whole or

in part, occurring after such adjustment, an amount in cash determined by multiplying (i) the fraction of such security (rounded to the nearest hundredth) by (ii) the excess, if any, of (A) the fair market value of the Common Stock on the exercise date over (B) the exercise price of the Option; provided, however, that if the fair market value of such fractional security immediately after such adjustment is less than the fair market value of one share of Common Stock immediately prior to such adjustment, such fractional security shall be disregarded and no payment shall be made.  The decision of the Committee regarding the amount and timing of any adjustment pursuant to this Section 9 shall be final, binding and conclusive.

For purposes of this Agreement, employment by the Company shall be deemed to include employment by a corporation which is a direct or indirect majority-owned subsidiary of the Company, employment by any other entity designated by the Board of Directors of the Company or the Committee in which the Company has a direct or indirect equity interest and employment by any corporation which succeeds to the obligations of the Company hereunder.

(a)  Optionee shall not, while employed by the Company and for a period of one year from the date of termination of Optionee’s employment with the Company for any reason, including termination by the Company with or without cause, directly or indirectly, either on Optionee’s own behalf or on behalf of any other person, firm or entity, solicit or provide services that are the same as or similar to the services the Company provided or offered while Optionee was employed by the Company to any customer or prospective customer of the Company (i) with whom Optionee had direct contact during the last two years of Optionee’s employment with the Company or about whom Optionee learned confidential information as a result of his or her employment with the Company and (ii) with whom any person over whom Grantee had supervisory authority at any time had direct contact during the last two years of Grantee’s employment with the Company or about whom such person learned confidential information as a result of his or her employment with the Company.

The Option is subject to the condition that if the listing, registration or qualification of the shares subject to the Option on any securities exchange or under any state or federal law, or if the assent or approval of any regulatory body shall be necessary as a condition of, or in

connection with, the granting of the Option or the delivery or purchase of shares thereunder, the Option may not be exercised in whole or in part unless and until such listing, registration, qualification, consent or approval shall have been effected or obtained.  The Company agrees to use its best efforts to obtain any such requisite listing, registration, qualification, consent or approval.  

The Committee, as from time to time constituted, shall have the right to determine any questions that arise in connection with this Agreement or the Option.  This Agreement and the Option are subject to the provisions of the Plan and shall be interpreted in accordance therewith.  

This Agreement shall not be construed as an employment contract and does not give Optionee any right to continued employment by the Company or any affiliate of the Company, and the fact that the termination of Optionee's employment occurs during the Option Term shall in no way be construed as giving Optionee the right to continue in the Company's or any such affiliate's employ.

The Option is intended to be a non-qualified stock option and shall not be treated as an incentive stock option within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended.

This Agreement shall be binding upon and shall inure to the benefit of any successor or successors of the Company and any person or persons who shall, upon the death of Optionee, acquire any rights in the Option.

Any notice, including a notice of exercise of the Option, required to be given hereunder to the Company shall be addressed to the Company at its headquarters in Chicago, Illinois, attention of the Corporate Secretary, and any notice required to be given hereunder to Optionee shall be addressed to Optionee at Optionee's residence address as shown in the Company's records, subject to the right of either party hereafter to designate in writing to the other some other address.  Any such notice shall be (i) delivered by personal delivery, facsimile, United States mail or by express courier service and (ii) deemed to be received upon personal delivery, upon confirmation of receipt of facsimile transmission or upon receipt if by United States mail or express courier service; provided, however, that if any notice is not received during regular business hours, it shall be deemed to be received on the next succeeding business day of the Company.  

The Option, this Agreement, and all determinations made and actions taken pursuant hereto and thereto, to the extent not governed by the laws of the United States, shall be governed by the laws of the State of Delaware and construed in accordance therewith without giving effect to principles of conflicts of laws.
