CHANGE-IN-CONTROL

AND

SEVERANCE PROTECTION AGREEMENT

THIS CHANGE-IN-CONTROL AND SEVERANCE PROTECTION AGREEMENT is entered into as of the 15^th day of January, 2008 by and between Robert K. Wiberg (“Executive”) and Brandywine Realty Trust (the “Company”), and shall be effective as of January 6, 2008.

WHEREAS, Executive is currently employed by the Company and/or a Subsidiary (as defined below) of the Company;

WHEREAS, in order to encourage Executive to remain an employee of the Company and/or a Subsidiary, the Company is entering into this Agreement with Executive.

NOW, THEREFORE, the parties hereto, intending to be legally bound, hereby agree as follows:

1. Payment Obligation: Change of Control. The Company agrees that if (i) a Change of Control of the Company occurs at a time when Executive is then an employee of the Company and/or a Subsidiary of the Company and (ii) within 730 days following the occurrence of the Change of Control (a) the Company or the purchaser or successor thereto (the “Purchaser”) terminates the employment of Executive other than for Cause or (b) Executive resigns for Good Reason:

a. then the Company or Purchaser will be obligated to pay to Executive an amount equal to the product of: (x) 2.0 multiplied by (y) the sum of (1) Executive’s annual base salary as in effect at the time the Change of Control occurs and (2) the annual bonus paid to Executive in the calendar year immediately preceding the calendar year in which the Change of Control occurs (unless the Board, at the time of grant of the bonus award, provides that the value of the bonus shall not be taken into account for purposes of this Agreement). Payment of the amounts provided for in this Section 1.a shall be made as soon as reasonably practicable following Executive’s termination or resignation, but, in any event, not later than ten (10) days after such termination or resignation.

b. Executive shall be entitled to medical coverage until the earlier of (1) the last day of the 730 day period following the date of termination or resignation or (2) the date on which the Executive is eligible for coverage under a plan maintained by a new employer or under a plan maintained by his spouse’s employer. Coverage shall be provided at the level in effect at the date of his termination or resignation (or generally comparable coverage) for himself and, where applicable, his spouse and dependents, as such coverage may be changed by the Company from time to time for employees generally, as if the Executive had continued in employment during such period; or, cash in lieu of such coverage in an amount equal to the Executive’s after-tax cost of continuing such coverage, where such coverage may not be continued (or where such continuation would adversely affect the tax status of the plan pursuant to which the coverage is provided). The COBRA health care continuation coverage period under section 4980B of the Code shall run concurrently with the foregoing benefit period. In addition, Executive shall be entitled to continuation of all group term life insurance benefits (but not including any supplemental life insurance benefits provided to executives), or the equivalent coverage if provision of such coverage is not possible under the group term life insurance policy, at no cost to Executive for the 730 day period following the date of Executive’s termination or resignation.

2. Payment Obligation: Death or Disability. The Company agrees that if Executive dies or becomes Disabled at a time when Executive is then an employee of the Company and/or a Subsidiary of the Company, then the Company will pay to Executive or his estate, as applicable, an amount equal to the product of: (x) 2.0 multiplied by (y) the sum of (1) Executive’s base salary as in effect at the time the death or Disability occurs and (2) the annual bonus paid to Executive in the calendar year immediately preceding the calendar year in which the death or Disability occurs.

3. No Right to Employment. This Agreement shall not confer upon Executive any right to remain an employee of the Company or a Subsidiary of the Company, and shall only entitle Executive to the payments and benefits in the limited circumstances set forth in Paragraphs 1 and 2 above.
