Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Performance Shares granted pursuant to Mr. Sipzner's employment agreement (as previously disclosed on Form 8-K) and will vest ratably over five years commencing March 20, 2008, and each successive January 15th thereafter until January 15, 2012.
(2) On February 15, 2007. Mr. Sipzner also received an award under the Brandywine Realty Trust (BDN) 2006 Long-Term Outperformance Compensation Program (the Program), a copy of which BDN previously filed as an exhibit to a Current Report on Form 8-K. The award represents a contingent right to receive 4.5% of a compensation pool that may be funded under the Program, payable in BDN common shares, if BDN's total shareholder return during the measurement period established under the Program exceeds specified hurdles and if the reporting person satisfies the vesting conditions applicable to his award. The number of BDN common shares, if any, that the reporting person would receive on account of his award will depend on the extent to which the performance hurdles are exceeded, the price of the BDN common share at the end of the measurement period and the reporting person's achievement of the vesting conditions applicable to his award.
(3) Shares of phantom stock were acquired under the Brandywine Realty Trust Executive Deferred Compensation Plan and are payable in common shares as elected by the reporting person pursuant to the Plan which may include such dates as termination of the reporting person's employment with the issuer or upon reaching a specific age and such shares are exempt from 16(b) pursuant to Rule 16b-3(d). The reporting person's account was credited with phantom stock at a rate of $34.49 per unit on February 15, 2007 on account of the deferral of a portion of his transition signing bonus pursuant to his employment agreement. Each phantom share has the equivalency of one common share.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
