BRANDYWINE REALTY TRUST AMENDED AND RESTATED EXECUTIVE DEFERRED COMPENSATION PLAN (As Amended and Restated, Effective January 1, 2013) ARTICLE 1 PURPOSE

The Board of Trustees of Brandywine Realty Trust (the “Board”) adopted the Brandywine Realty Trust Executive Deferred Compensation Plan (the “Plan”), effective January 1, 2005 (the “Effective Date”). Effective March 31, 2006 (the “Transfer Date”), all of the assets, liabilities and obligations under the Prentiss Properties Executive Choice Share Deferral Plan, the Prentiss Properties Executive Choice Deferred Compensation Plan, the Prentiss Properties Executive Choice Deferred Compensation Plan for Trustees and the Prentiss Properties Executive Choice Share Deferral Plan for Trustees, were assumed by the Plan, and such Prior Plans were terminated. This amendment and restatement, effective January 1, 2013 (the “Restatement Date”), except as otherwise provided herein, also includes certain other changes with respect to payment events and other clarifying changes.

Prior to the Effective Date, the Pre-2005 Brandywine Realty Trust Executive Deferred Compensation Plan (the “Pre-2005 EDCP”) was in effect. In order to preserve the favorable tax treatment available to deferrals under the Pre-2005 EDCP due to the American Jobs Creation Act of 2004, the regulations and Internal Revenue guidance issued thereunder (collectively, the “AJCA”), the Board froze the Pre-2005 EDCP with respect to amounts earned and vested on and after the Effective Date. Amounts earned and vested prior to the Effective Date are and will remain subject to the terms of the Pre-2005 EDCP.

All amounts earned and vested on and after the Effective Date are subject to the terms of the Plan. The Plan retains many of the attributes of the Pre-2005 EDCP, but is modified so as to achieve compliance with the requirements of the AJCA. The Board reserves the right to amend the Plan, either retroactively or prospectively, in whatever respect is required to achieve compliance with the requirements of the AJCA.

With respect to the deferral of Performance-Based Compensation, an executed Enrollment Agreement must be filed no later than six months prior to the end of the Performance Period during which such Performance-Based Compensation is earned, subject to such other administrative rules, procedures and earlier deadlines as may be set by the Plan Administrator and communicated with reasonable advance notice to Eligible Employees.

(b)Amount of Deferral. Pursuant to said Enrollment Agreement, the Eligible Employee or Trustee shall irrevocably elect the percentages by which (as a result of payroll deduction) an amount equal to any whole percentage of the Participant's Compensation, Performance-Based Compensation, Share Award or Board Remuneration will be deferred.

Amounts in a Prior Plan Sub-Account shall be distributed to the Participant in accordance with the election or elections the Eligible Employee has made under the applicable Prior Plan with respect to such amounts.

4.2Special Rules for Filing of Elections.

(a)New Hires and Offerees. The Plan Administrator may, in its discretion, permit an Employee or Offeree who becomes an Eligible Employee to enroll in the Plan for the Plan Year in which the Employee or Offeree became an Eligible Employee by filing a completed and fully executed Enrollment Agreement, in accordance with Section 4.1, prior to or as soon as practicable after the date the Employee or Offeree becomes an Eligible Employee but, in any event, not later than 30 days after such date. Notwithstanding the foregoing, however, any election by an Eligible Employee to defer Share Awards, Compensation and Performance-Based Compensation pursuant to this Section 4.2(a) shall apply only to Share Awards, Compensation and Performance-Based Compensation earned by or awarded to the Eligible Employee after the date on which such Enrollment Agreement is filed. Alternatively, the Plan Administrator may require an Employee or Offeree who becomes an Eligible Employee after the beginning of a Plan Year to enroll in the next subsequent Plan Year, by filing a completed and fully executed Enrollment Agreement, in accordance with Section 4.1 during the next scheduled open enrollment period that Brandywine Realty Trust conducts an open enrollment for the Plan.

(b)Promotions. The Plan Administrator may, in its discretion, permit an Employee who first becomes an Eligible Employee after the beginning of a Plan Year due to a promotion, to enroll in the Plan for that Plan Year by filing a completed and fully executed Enrollment Agreement, in accordance with Section 4.1, as soon as practicable following the date the Employee becomes an Eligible Employee but, in any event, not later than 30 days after such date. Notwithstanding the foregoing, however, any election by an Eligible Employee to defer Share Awards, Compensation and Performance-Based Compensation pursuant to this Section 4.2(b) shall apply only to Share Awards, Compensation and Performance-Based Compensation earned by or awarded to the Eligible Employee after the date on which such Enrollment Agreement is filed.

(c)New Trustees. A Trustee whose election as a member of the Board first becomes effective in a Plan Year may enroll in the Plan for that Plan Year by filing a completed and fully executed Enrollment Agreement, in accordance with Section 4.1, as soon as practicable following the effective date of such Trustee's election but, in any event, not later than 30 days after the effective date of such election. Notwithstanding the foregoing, however, any election by a Trustee to defer Board Remuneration pursuant to this Section 4.2 shall apply only to such Board Remuneration earned by the Trustee after the date on which such Enrollment Agreement is filed.

4.3Matching Contributions.

(a)If: (1) the dollar amount of the matching contributions under the 401(k) Plan for the Plan Year was limited due to the application of the provisions of Section 401(m) of the Code; (2) the percentage of the Participant's Compensation that could be deferred under the 401(k) Plan was limited to an amount less than 10% (or such other percentage that may become effective after the Effective Date) because of other Code limitations; or (3) to the extent that a Participant's compensation for purposes of the 401(k) Plan is reduced to an amount that is below the Compensation Limit in any Plan Year by reason of deferrals made under this Plan (regardless of whether, prior to reduction, it was in excess of such limitation), a Matching Contribution shall be contributed under the Plan equal to the amount of matching contributions that would have been made to the 401(k) Plan but for such limitations, but only if and to the extent the Participant has deferred additional amounts of Compensation to the Plan at least equal to the amount that would have been required to have been deferred under the 401(k) Plan in order to support such additional matching contributions in the absence of such limitations.

(b)In its discretion, the Company may make Matching Contributions, which, if made, shall be credited to a Participant's Retirement Distribution Account. Generally, the Matching Contribution shall be equal to the “matching percentage” (30%, as of the Effective Date) set forth in the 401(k) Plan, multiplied by a specified percentage (10%, as of the Effective Date) of the Participant's Compensation in excess of the Compensation Limit that is deferred under Section 4.1 or 4.2(a) or (b), as applicable.

4.4Profit Sharing Contributions. The Company may credit to each Participant's Retirement Distribution Account a Profit Sharing Contribution. Profit Sharing Contributions will be credited as frequently as determined by the Plan Administrator.

4.5Supplemental Profit Sharing Contributions. To the extent that a Participant's compensation for purposes of the 401(k) Plan is reduced to an amount that is below the Compensation Limit in any Plan Year by reason of deferrals made under this Plan (regardless of whether, prior to reduction, it was in excess of such limitation), a Supplemental Profit Sharing Contribution shall be credited to the Retirement Distribution Account of such Participant, at least annually, equal to the specified profit sharing percentage for the applicable Plan Year (if any), multiplied by the excess, if any, of (a) the lesser of (i) the Participant's Compensation or (ii) the Compensation Limit over (b) the amount of the Participant's compensation that is taken into account under the 401 (k) Plan.

4.6Additional Company Contributions.

(a)If, pursuant to Section 4.1 or 4.2, a Participant (other than a Participant who is a Trustee) elects to defer receipt of 25% of his annual bonus (if any), which may or may not qualify as Performance-Based Compensation, and deems that such deferral be invested in the Employer Stock Fund, then, with respect to any part of such bonus in excess of 25% that is deferred and invested in the Employer Stock Fund (“Excess Bonus”), an Additional Company Contribution equal to a specified percentage (15% as of the Effective Date) of the Excess Bonus shall be contributed to such Participant's Retirement Distribution Account and deemed invested in the Employer Stock Fund. Notwithstanding the preceding provisions of this Section 4.6(a), if the Committee determines in its sole discretion that a Participant has met the Brandywine Realty Trust target shareholding requirements, to the extent that such a Participant elects to defer receipt of his annual bonus and deems that such deferral be invested in the Employer Stock Fund, which deferral shall also be referred to as “Excess Bonus” for purposes of the Plan, an Additional Company Contribution equal to a specified percentage (15% as of the Effective Date) of such Excess Bonus shall be contributed to such Participant's Retirement Distribution Account and deemed invested in the Employer Stock Fund.

(b)The Excess Bonus and associated Additional Company Contribution shall not be subject to Participant investment direction for two years from the date of crediting; provided, however, that Excess Bonus and associated Additional Company Contributions shall not be subject to Participant investment direction on and after April 1, 2007. Prior to April 1, 2007, if, prior to the expiration of two years from the date on which the Excess Bonus and Additional Company Contribution are credited, (1) the Participant directs that all or a portion of the Excess Bonus or the associated Additional Company Contribution be deemed invested in an Earnings Crediting Option other than the Employer Stock Fund or (2) the Participant receives a distribution pursuant to Article 10, any portion of which consists of all or a portion of such Excess Bonus or Additional Company Contribution, then the Participant shall forfeit all of such Additional Company Contribution.

5.1Distribution Option Accounts. The Plan Administrator shall establish and maintain separate Distribution Option Accounts with respect to a Participant. A Participant's Distribution Option Accounts shall consist of the Retirement Distribution Account, one or more Flexible Distribution Accounts, and/or a Deferred Board Remuneration Account, as applicable. The amount of Compensation, Performance-Based Compensation and Board Remuneration, and Shares subject to a Share Award, deferred pursuant to Section 4.1 or Section 4.2 shall be credited by the Company to the Participant's Distribution Option Accounts, in accordance with the Distribution Option irrevocably elected by the Participant in the Enrollment Agreement, as soon as reasonably practicable following the close of the payroll period, bonus payment date, or, in the case of Trustees, the regularly scheduled payment date, or, in the case of Share Awards, the vesting date, for which the deferred Compensation, Performance-Based Compensation, Board Remuneration and Share Awards would otherwise be payable or vested, as determined by the Plan Administrator in its sole discretion. Any amount once taken into account as Compensation, Performance-Based Compensation or Board Remuneration for purposes of this Plan shall not be taken into account thereafter. Matching Contributions, Additional Company Contributions, Profit Sharing Contributions, and Supplemental Profit Sharing Contributions, when credited, as determined by the Plan Administrator in its sole discretion, are credited only to the Retirement Distribution Account. The Participant's Distribution Option Accounts shall be reduced by the amount of payments or Share distributions made by the Company to the Participant or the Participant's Beneficiary pursuant to this Plan.

5.2Earnings on Distribution Option Accounts.

(a)General. A Participant's Distribution Option Accounts shall be credited with earnings in accordance with the Earnings Crediting Options elected by the Participant from time to time. Participants may allocate their Retirement Distribution Account, each of their Flexible Distribution Accounts, and/or their Deferred Board Remuneration Account among the Earnings Crediting Options available under the Plan only in whole percentages of not less than one percent (1%); provided, however, that the portion of a Participant's Distribution Option Account that is attributable to a Share Award shall only be invested in the Employer Stock Fund. The Company reserves the right, on a prospective basis, to add or delete Earnings Crediting Options.

(b)Investment Options.

(i)Investment Performance. The deemed rate of return, positive or negative, credited under each Earnings Crediting Option is based upon the actual investment performance of (A) the Employer Stock Fund, (B) the corresponding investment portfolios of the EQ Advisers Trust, open-end investment management companies under the Investment Company Act of 1940, as amended from time to time, or (C) such other investment fund(s) as the Company may designate from time to time, and shall equal the total return of such investment fund net of asset based charges, including, without limitation, money management fees, fund expenses and mortality and expense risk insurance contract charges.

(ii)Dividends. Dividends creditable to deferral amounts and Share Awards invested in the Employer Stock Fund shall be treated as a separate arrangement subject to the provisions of Appendix A.

5.3Earnings Crediting Options. Notwithstanding that the rates of return credited to Participants' Distribution Option Accounts under the Earnings Crediting Options are based upon the actual performance of the investment options specified in Section 5.2, or such other investment funds as the Company may designate, the Company shall not be obligated to invest any Compensation, Performance-Based Compensation or Board Remuneration deferred by Participants under this Plan, Matching Contributions, Additional Company Contributions, Profit Sharing Contributions, Supplemental Profit Sharing Contributions, or any other amounts, in such portfolios or in any other investment funds.

5.4Changes in Earnings Crediting Options.

(a)General. Except as otherwise provided in Section 5.4(b) below, a Participant may change the Earnings Crediting Options to which his Distribution Option Accounts are deemed to be allocated, subject to such rules as may be determined by the Plan Administrator, provided that except as the Plan Administrator may otherwise determine in light of legal restrictions on changes, the frequency of permitted changes among Earnings Crediting Options shall not be less than four times per Plan Year. Each such change may include (a) reallocation of the Participant's existing Accounts in whole percentages of not less than one percent (1%), and/or (b) change in investment allocation of amounts to be credited to the Participant's Accounts in the future, as the Participant may elect. The effect of a Participant's change in Earnings Crediting Options shall be reflected in the Participant's Accounts as soon as reasonably practicable following the Plan Administrator's receipt of notice of such change, as determined by the Plan Administrator in its sole discretion.

(b)Employer Stock Fund Changes. For deferral elections effective on and after January 1, 2007, amounts or Share Awards deferred and invested in the Employer Stock Fund may not be reallocated to any other Earnings Crediting Option and shall instead remain invested in the Employer Stock Fund until distributed. For amounts deferred prior to January 1, 2007, (i) a Participant may change the Earnings Crediting Option to which the portions of his Distribution Option Accounts are invested in the Employer Stock Fund subject to such rules as may be determined by the Plan Administrator, (ii) provided that such reallocation election is received on or prior to March 31, 2007, and (iii) further provided that such deferral amounts that remain invested in the Employer Stock Fund as of April 1, 2007 may not be reallocated thereafter to any other Earnings Crediting Option and shall instead remain invested in the Employer Stock Fund until distributed.

5.5Valuation of Accounts. Except as otherwise provided in Section 5.7, the value of a Participant's Distribution Option Accounts as of any date shall equal the amounts theretofore credited to such Accounts, including any earnings (positive or negative) deemed to be earned on such Accounts in accordance with Section 5.2 and Section 5.4 through such date, less the amounts theretofore deducted from such Accounts.

5.6Statement of Accounts. The Plan Administrator shall provide to each Participant, not less frequently than quarterly, a statement in such form as the Plan Administrator deems desirable for setting forth the balance standing to the credit of each Participant in each of his Distribution Option Accounts.

5.7Distributions from Accounts. Any distribution made to or on behalf of a Participant from one or more of his Distribution Option Accounts in an amount which is less than the entire balance of any such Account shall be made pro rata from each of the Earnings Crediting Options to which such Account is then allocated. For purposes of any provision of the Plan relating to distribution of benefits to Participants or Beneficiaries, the value of a Participant's Distribution Option Accounts shall be determined as of a date as soon as reasonably practicable preceding the Distribution Date, as determined by the Plan Administrator in its sole discretion. In the case of any benefit payable in the form of a cash lump sum, the value of a Participant's Distribution Option Accounts, as determined pursuant to this Section 5.7, shall be distributed. In the case of any benefit payable in the form of annual installments, as of any payment date, the amount of each installment payment shall be determined as the quotient of (a) the value of the Participant's Distribution Option Account subject to distribution, as determined pursuant to this Section 5.7, divided by (b) the number of remaining annual installments immediately preceding the payment date. In the case of any benefit attributable to a deferral that was effective on or after January 1, 2007, or in the case of any benefit attributable to a deferral effective prior to January 1, 2007 and invested in the Employer Stock Fund as of April 1, 2007, such benefit shall only be payable in the form of Shares (and cash for fractional Shares).

5.8Small Benefit Cash-Out. If a Participant or Beneficiary becomes eligible for a distribution in accordance with the provisions of Sections 7.1(b), 7.2(b), 7.4(c), 8.1 or 9.1, relating to payments following termination of Service, Disability or death, the Plan Administrator reserves the right to cash out such Participant or Beneficiary as soon as administratively practicable provided that the value of the Participant's Distribution Option Accounts, together with any other deferred amounts under agreements, methods, programs, or other arrangements treated with the Plan as a single nonqualified deferred compensation plan under Treas. Reg. 1.409A-1(c)(2) (or any succeeding regulations), is not greater than the applicable dollar amount under Section 402(g)(1)(B) of the Code as of the Participant's termination of Service, Disability or death.

6.1Election of Distribution Option. In the first completed and fully executed Enrollment Agreement filed with the Plan Administrator, a Participant shall elect the time and manner of payment in accordance with Section 4.1(d). Annually, the Participant shall allocate his or her deferrals among the Distribution Options in such increments as may be prescribed by the Plan Administrator; provided that, deferrals of Board Remuneration shall automatically be allocated to the Deferred Board Remuneration Account.

6.4Deferred Board Remuneration Option. Subject to Section 7.3, distribution of the Participant's Deferred Board Remuneration Account, if any, shall commence following the Participant's termination of service as a Trustee.

6.5Flexible Distribution Option. Subject to Section 7.4, each of the Participant's Flexible Distribution Accounts shall be distributed commencing in the year elected by the Participant in the Enrollment Agreement pursuant to which such Flexible Distribution Account was established; provided, however, such distribution shall not be prior to the third Plan Year beginning after the Plan Year in which the first deferral election is made with regard to that Flexible Distribution Account.

(b)Changes in Distribution Elections. A Participant may elect to change the form and commencement date of payment of the Participant's Deferred Board Remuneration Account, consistent with Section 7.3(a), by filing a Re-Deferral Election within the 30-day period following the Participant's termination of service as a Trustee. Limitations on the form and commencement date under a Re-Deferral Election shall be determined by the Plan Administrator in its sole discretion.

7.4Benefits Under the Flexible Distribution Account. Benefits under the Flexible Distribution Option shall be paid to a Participant as follows:

(a)General. Each of the Participant's Flexible Distribution Accounts shall be distributed in one lump sum, or up to 5 annual installments as elected (including Shares for applicable amounts under the Employer Stock Fund) not later than January 31 of the Plan Year irrevocably elected by the Participant in the Enrollment Agreement pursuant to which such Flexible Distribution Account was established.

The Participant may elect to change the form and commencement date of payment of any of the Participant's Flexible Distribution Accounts by making a Re-Deferral Election. Limitations on the form and commencement date under a Re-Deferral Election shall be determined by the Plan Administrator in its sole discretion; provided that, the Company reserves the right to override the Participant's election and distribute any of the Participant's Flexible Distribution Accounts in a lump sum not earlier than 13 months following the Termination Date.

In the event a Participant becomes Disabled, the Participant's right to make any further deferrals under this Plan shall terminate as of the date the Participant terminates due to Disability. The Participant's Distribution Option Accounts shall continue to be credited with earnings in accordance with Section 5.2 until such Accounts are fully distributed. The Participant's Distribution Option Accounts, including any Distribution Option Account as to which distributions have already commenced and notwithstanding any election to the contrary, shall be paid in a lump sum (including Shares for applicable amounts under the Employer Stock Fund) at the earliest Distribution Date within 90 days following such Participant's becoming Disabled.

In the event of a Participant's death, payment of all Distribution Option Accounts, including any Distribution Option Account as to which distributions have already commenced, shall be made in a lump sum (including Shares for applicable amounts under the Employer Stock Fund) within 90 days following the Participant's death.

In the event that the Plan Administrator, upon written request of a Participant, determines, in its sole discretion, that the Participant has suffered an Unforeseeable Emergency, the Company shall pay to the Participant from the Participant's Distribution Option Account, as soon as practicable following such determination, an amount necessary to meet such Unforeseeable Emergency, in a manner consistent with the AJCA, after deduction of any and all taxes as may be required pursuant to Section 11.10 (the “Emergency Benefit”). Emergency Benefits shall be paid first from the Participant's Flexible Distribution Accounts, if any, to the extent the balance of one or more of such Flexible Distribution Accounts is sufficient to meet the emergency, in the order in which such Accounts would otherwise be distributed to the Participant. If the distribution exhausts the Flexible Distribution Accounts, the Retirement Distribution Account, and the Deferred Board Remuneration Account, if necessary. With respect to that portion of any Distribution Option Account which is distributed to a Participant as an Emergency Benefit in accordance with this Article 10, no further benefit shall be payable to the Participant under this Plan. Notwithstanding anything in this Plan to the contrary, a Participant who receives an Emergency Benefit in any Plan Year shall not be entitled to make any further deferrals for the remainder of such Plan Year.

11.1Amendment and Termination. The Plan may be amended, suspended, discontinued or terminated at any time by the Plan Administrator; provided, however, that no such amendment, suspension, discontinuance or termination shall reduce or in any manner adversely affect the rights of any Participant with respect to benefits that are payable or may become payable under the Plan based upon the balance of the Participant's Accounts as of the effective date of such amendment, suspension, discontinuance or termination. This Section 11.1 shall be applied consistent with Treas. Reg. 1.409A-3(j)(4)(ix), or any succeeding regulations.

11.2Change of Control.

(a)Notwithstanding Section 11.1, in the event of a Change of Control, Brandywine Realty Trust, or its successor, shall have the discretion, with respect to amounts standing to the credit of Participants' Distribution Option Accounts, to terminate the Plan and provide for a complete distribution of all amounts due to Participants under the Plan, consistent with and to the extent permitted by, Treas. Reg. 1.409A-3(j)(4)(ix), or any succeeding regulations.

(b)In the event of a Change of Control in which Shares are converted into cash or equity, amounts deemed invested in the Employer Stock Fund as of such Change of Control shall be deemed to be converted in the same manner as Shares; provided if holders of Shares are given a choice between forms of consideration, the amounts deemed invested in the Employer Stock Fund as of such Change of Control shall be deemed converted into that form of consideration chosen by the majority of the holders of Shares.

11.3Claims Procedure.

(a)Claim. A person who believes that he is being denied a benefit to which he is entitled under the Plan (hereinafter referred to as a “Claimant”) may file a written request for such benefit with the Plan Administrator, setting forth the claim.

(b)Claim Decision. Upon receipt of a claim, the Plan Administrator shall advise the Claimant within ninety (90) days of receipt of the claim whether the claim is denied. If special circumstances require more than ninety (90) days for processing, the Claimant will be notified in writing within ninety (90) days of filing the claim that the Plan Administrator requires up to an additional ninety (90) days to reply. The notice will explain what special circumstances make an extension necessary and indicate the date a final decision is expected to be made. If the Claimant does not receive a written denial notice or notice of an extension within ninety (90) days, the Claimant may consider the claim denied and may then request a review of denial of the claim, as described below. If the claim is denied in whole or in part, the Claimant shall be provided a written opinion, using language calculated to be understood by the Claimant, setting forth:

(i)The specific reason or reasons for such denial;

(ii)The specific reference to pertinent provisions of this Plan on which such denial is based;

(iii)A description of any additional material or information necessary for the Claimant to perfect his claim and an explanation why such material or such information is necessary;

(iv)Appropriate information as to the steps to be taken if the Claimant wishes to submit the claim for review; and

(v)The time limits for requesting a review under subsection (c) and for review under subsection (d) hereof and a statement regarding the Claimant's right to bring suit under section 502(a) of ERISA following an adverse determination on review.

(c)Request for Review. Within sixty (60) days after the receipt by the Claimant of the written opinion described above, the Claimant may request in writing that the Plan Administrator review its determination. The Claimant or his duly authorized representative may, but need not, review the pertinent documents and submit issues and comments in writing for consideration by the Plan Administrator. If the Claimant does not request a review of the initial determination within such sixty (60) day period, the Claimant shall be barred and estopped from challenging the determination.

(d)Review of Decision. Within sixty (60) days after the Plan Administrator's receipt of a request for review, it will review the initial determination. If special circumstances require that the sixty (60) day time period be extended, the Plan Administrator will so notify the Claimant and will render the decision as soon as possible, but no later than one hundred twenty (120) days after receipt of the request for review. After considering all materials presented by the Claimant, the Plan Administrator will render a written opinion, written in a manner calculated to be understood by the Claimant, setting forth the specific reasons for the decision, containing specific references to the pertinent provisions of the Plan on which the decision is based, including a statement that the Claimant is entitled upon request and at no charge reasonable access to, and copies of, all documents, records and other information relevant to the Claimant's claim for benefits, and including a statement of the right of the Claimant to bring suit under section 502(a) of ERISA after the Claimant has exhausted the Plan's claims review procedures set forth above.

11.4Designation of Beneficiary. Each Participant may designate a Beneficiary or Beneficiaries (which Beneficiary may be an entity other than a natural person) to receive any payments which may be made following the Participant's death. Such designation may be changed or canceled at any time without the consent of any such Beneficiary. Any such designation, change or cancellation must be made in a form approved by the Plan Administrator and shall not be effective until received by the Plan Administrator, or its designee. If no Beneficiary has been named, or the designated Beneficiary or Beneficiaries shall have predeceased the Participant, the Beneficiary shall be the Participant's estate. If a Participant designates more than one Beneficiary, the interests of such Beneficiaries shall be paid in equal shares, unless the Participant has specifically designated otherwise.

11.5Limitation of Participant's Right. Nothing in this Plan shall be construed as conferring upon any Participant any right to continue in Service or to continue to serve as a Trustee, nor shall it interfere with the rights of the Company to terminate the employment of any Participant and/or to take any personnel action affecting any Participant without regard to the effect which such action may have upon such Participant as a recipient or prospective recipient of benefits under the Plan. Any amounts payable hereunder shall not be deemed salary or other compensation to a Participant for the purposes of computing benefits to which the Participant may be entitled under any other arrangement established by the Employer for the benefit of its employees.

11.6No Limitation on Company Actions. Nothing contained in the Plan shall be construed to prevent the Company from taking any action which is deemed by it to be appropriate or in its best interest. No Participant, Beneficiary, or other person shall have any claim against the Company as a result of such action.

11.7Obligations to Company. If a Participant becomes entitled to a distribution of benefits under the Plan, and if at such time the Participant has outstanding any debt, obligation, or other liability representing an amount owing to the Employer, then the Employer may offset such amount owed to it against the amount of benefits otherwise distributable. Such determination shall be made by the Plan Administrator.

11.8Nonalienation of Benefits. Except as expressly provided herein, no Participant or Beneficiary shall have the power or right to transfer (otherwise than by will or the laws of descent and distribution), alienate, or otherwise encumber the Participant's or Beneficiary's interest under the Plan. The Company's obligations under this Plan are not assignable or transferable, except to (a) any corporation or partnership which acquires all or substantially all of the Company's assets or (b) any corporation or partnership into which the Company may be merged or consolidated. A Participant's or Beneficiary's interest under the Plan is not assignable or transferable pursuant to a domestic relations order. The provisions of the Plan shall inure to the benefit of each Participant and the Participant's Beneficiaries, heirs, executors, administrators or successors in interest.

11.9Protective Provisions. Each Participant shall cooperate with the Company by furnishing any and all information requested by the Company in order to facilitate the payment of benefits hereunder, taking such physical examinations as the Company may deem necessary and taking such other relevant action as may be requested by the Company. If a Participant refuses to cooperate, the Company shall have no further obligation to the Participant under the Plan, other than payment to such Participant of the then current balance of the Participant's Distribution Option Accounts in accordance with his prior elections.

11.10Taxes. The Company may make such provisions and take such action as it may deem appropriate for the withholding of any taxes which the Company is required by any law or regulation of any governmental authority, whether Federal, state or local, to withhold in connection with any benefits under the Plan, including, but not limited to, the withholding of appropriate sums from any amount otherwise payable to the Participant (or his Beneficiary). Each Participant, however, shall be responsible for the payment of all individual tax liabilities relating to any such benefits.

11.11Unfunded Status of Plan. The Plan is an “unfunded” plan for tax and Employee Retirement Income Security Act purposes. This means that the value of a Participant's Distribution Option Accounts is based on the value assigned to a hypothetical bookkeeping account, which is invested in hypothetical shares of investments funds available under the Plan. As the nature of the investment fund which forms the “index” or “meter” for the valuation of the bookkeeping account changes, the valuation of the bookkeeping account changes as well. The amount owed to a Participant is based on the value assigned to the bookkeeping account. Brandywine Realty Trust may decide to use a “rabbi trust” to anticipate its potential Plan liabilities, and it may attempt to have Plan investments mirror the hypothetical investments deemed credited to the bookkeeping accounts. However, the liability to pay the benefits is Brandywine Realty Trusts', and the assets of the rabbi trust are potentially available to satisfy the claims of non-participant creditors of Brandywine Realty Trust.

11.12Severability. If any provision of this Plan is held unenforceable, the remainder of the Plan shall continue in full force and effect without regard to such unenforceable provision and shall be applied as though the unenforceable provision were not contained in the Plan.

11.13Governing Law. The Plan shall be construed in accordance with and governed by the laws of the Commonwealth of Pennsylvania, without reference to the principles of conflict of laws.

11.14Headings. Headings are inserted in this Plan for convenience of reference only and are to be ignored in the construction of the provisions of the Plan.

11.15Gender, Singular and Plural. All pronouns and any variations thereof shall be deemed to refer to the masculine, feminine, or neuter, as the identity of the person or persons may require. As the context may require, the singular may read as the plural and the plural as the singular.

11.16Notice. Any notice or filing required or permitted to be given to the Plan Administrator under the Plan shall be sufficient if in writing and hand delivered, or sent by registered or certified mail, to Brandywine Realty Trust, 401 Plymouth Road, Suite 500, Plymouth Meeting, PA 19462, Attention: Chief Accounting Officer, or to such other entity as the Plan Administrator may designate from time to time. Such notice shall be deemed given as to the date of delivery, or, if delivery is made by mail, as of the date shown on the postmark on the receipt for registration or certification.

11.17Section 409A of the Code. The Plan is intended to comply with the requirements of section 409A of the Code, and shall in all respects be administered in accordance with section 409A of the Code. Notwithstanding anything in the Plan to the contrary, distributions may only be made under the Plan upon an event and in a manner permitted by section 409A of the Code, including the requirement that “specified employees,” as such term is defined in section 409A of the Code, may not receive distributions prior to the end of the six-month period following a “separation from service” (within the meaning of such term under section 409A of the Code). If a distribution is not made by the designated payment date under the Plan, the payment shall be made by December 31 of the calendar year in which the designated payment date occurs. To the extent that any provision of the Plan would cause a conflict with the requirements of section 409A of the Code, or would cause the administration of the Plan to fail to satisfy the requirements of section 409A of the Code, such provision shall be deemed null and void to the extent permitted by applicable law. A Participant cannot designate the year of a payment except in accordance with the rules relating to payment elections under section 409A of the Code.

Dividends creditable to deferral amounts and Share Awards invested in the Employer Stock Fund shall either be (A) paid in cash as soon as administratively practicable following the dividend payment date if the Participant has made a separate election under an Enrollment Agreement to receive such dividends in cash, or (B) credited to the Participant's account and invested in an Earnings Crediting Option other than the Employer Stock Fund, as elected by the Participant. The Committee reserves the right, as to the Employer Stock Fund, to prescribe such other rules regarding the manner in which deemed dividends are invested or distributed. The dividend election opportunity, as described in this Appendix A, is intended to constitute a separate deferral arrangement within the meaning of the AJCA.
