In the discretion of the Committee, any cash or substitute consideration payable upon cancellation of the Option may be subjected to earn-out, escrow, holdback or similar arrangements, to the extent such arrangements are applicable to any consideration paid to shareholders in connection with the Change in Control.

4. Payment for Shares. Full payment for Shares purchased upon the exercise of an Option may be made in cash. In addition, this Option may be exercised through means of a “net settlement,” whereby the Option Price will be satisfied by cancellation of the Company’s obligation to issue a number of Common Shares otherwise issuable upon such exercise, which number of Common Shares will be equal to: (A) the total Option Price payable to acquire the number of Shares as to which the Option is then being exercised divided by (B) the then current Fair Market Value per Common Share. The number of Shares actually issuable upon such exercise will then be equal to the difference between the number of Shares as to which the Option is then being exercised and the number of Shares described in the preceding sentence. Without limiting the foregoing, payment for Shares purchased upon the exercise of an Option may, at the election of the Optionee and as the Committee may, in its discretion, approve, by surrendering Common Shares with an aggregate Fair Market Value equal to the aggregate Option Price.

5. Manner of Exercise. The Option shall be exercised by giving written notice of exercise to:

Brandywine Realty Trust
555 East Lancaster Avenue
Suite 100
Radnor, PA 19087
Attention: General Counsel

All notices under this agreement shall be deemed to have been given when hand-delivered, telecopied or transmitted electronically and shall be irrevocable once given.

6. Nontransferability of Option. The Option may not be transferred or assigned by the Optionee otherwise than as and to the extent permitted by Section 5(e) of the Plan; and any attempt at assignment or transfer contrary to the provisions of the Plan or the levy of any execution, attachment or similar process upon the Option shall be null and void and without effect. Any exercise of the Option by a person other than the Optionee shall be accompanied by appropriate proofs of the right of such person to exercise the Option.

7. Securities Laws. The Committee may from time to time impose any conditions on the exercise of the Option as it deems necessary or appropriate to comply with the then-existing requirements of the Securities Act of 1933, as amended, or of the Securities Exchange Act of 1934, as amended, including Rule 16b-3 (or any similar rule) of the Securities and Exchange Commission. If the listing, registration or qualification of Shares issuable on the exercise of the Option upon any securities exchange or under any federal or state law, or the consent or approval of any governmental regulatory body is necessary as a condition of or in connection with the purchase of such Shares, the Company shall not be obligated to issue or

deliver the certificates (if any) representing the Shares otherwise issuable on the exercise of the Option unless and until such listing, registration, qualification, consent or approval shall have been effected or obtained. If registration is considered unnecessary by the Company or its counsel, the Company may cause a legend to be placed on such Shares calling attention to the fact that they have been acquired for investment and have not been registered.

8. Issuance of Certificate at Closing; Payment of Cash. Subject to the provisions of this Paragraph 8, the Closing Date shall occur as promptly as is feasible after the exercise of the Option. Subject to the provisions of Paragraphs 7 and 9 hereof, a certificate for the Shares issuable on the exercise of the Option shall be delivered to the Optionee or to his personal representative, heir or legatee at the Closing, provided that no certificates for Shares will be delivered to the Optionee or to his personal representative, heir or legatee unless the Option Price has been paid in full and provided further that the Company may elect to provide for the issuance and delivery of the Shares via book entry or in uncertificated form.

9. Rights Prior to Exercise. The Optionee shall not have any right as a shareholder with respect to any Shares subject to his Options until the Option shall have been exercised in accordance with the terms of the Plan and this Award and the Optionee shall have paid the full purchase price for the number of Shares in respect of which the Option was exercised, provided that in the event that the Optionee’s employment with the Company is terminated for Cause, upon a determination by the Committee, the Optionee shall automatically forfeit all Shares otherwise subject to delivery upon exercise of an Option but for which the Company has not yet delivered the Share certificates or issued the Shares via book entry or in uncertificated form, upon refund by the Company of the Option Price.

10. Status of Option; Interpretation. The Option is intended to be a non-qualified stock option. Accordingly, it is intended that the transfer of property pursuant to the exercise of the Option shall be subject to federal income tax in accordance with section 83 of the Code. The Option is not intended to qualify as an incentive stock option within the meaning of section 422 of the Code. The interpretation and construction of any provision of this Option or the Plan made by the Committee shall be final and conclusive and, insofar as possible, shall be consistent with the intention expressed in this Paragraph 10.

11. Option Not to Affect Employment. The Option granted hereunder shall not confer upon the Optionee any right to continue in the employment of the Company or any Subsidiary.

12. Miscellaneous.

(a) The address for the Optionee to which notice, demands and other communications to be given or delivered under or by reason of the provisions hereof shall be the address contained in the Company’s personnel records.

(b) This Award and all questions relating to its validity, interpretation, performance, and enforcement shall be governed by and construed in accordance with the laws of the State of Maryland.

13. Withholding of Taxes. Whenever the Company proposes or is required to deliver or transfer Shares in connection with the exercise of the Option, the Company shall have the right to (a) require the Optionee to remit to the Company an amount in cash or Common Shares (valued at the then current Fair Market Value) sufficient to satisfy any federal, state and/or local withholding tax requirements prior to the delivery or transfer of any certificate or certificates for such Shares or (b) take whatever action it deems necessary to protect its interests with respect to tax liabilities.

IN WITNESS WHEREOF, the Company has granted this Award on the day and year first above written.
