2023-2025 Performance Share Unit Program

1.Background; Purpose.

Brandywine Realty Trust (the “Trust”) established, and its shareholders approved, the Brandywine Realty Trust Amended and Restated 1997 Long-Term Incentive Plan (the “Plan”), primarily in order to award equity and equity-based benefits to officers, employees and Trustees of the Trust and its Subsidiaries (as defined in the Plan).

One kind of equity-based benefit that can be awarded under the Plan is a “Performance Share,” which entitles the recipient to receive Shares (as defined in the Plan), without payment, following the attainment of designated performance goals.

The Compensation Committee (the “Committee”) of the Trust’s Board of Trustees is responsible for the administration of the Plan and may, pursuant to the powers granted to it thereunder, adopt rules and regulations for the administration of the Plan and determine the terms and conditions of each award granted thereunder.

The Committee desires to establish, and effective as of January 1, 2023 has established, a program under the Plan known as the “Brandywine Realty Trust 2023-2025 Restricted Performance Share Unit Program” for the 2023 through 2025 period for the benefit of certain officers of the Trust and Subsidiaries whereby such officers would receive Performance Shares under the Plan. The purposes of the Program are to motivate certain officers of the Trust to achieve challenging goals for the Trust that reflect value creation for shareholders, and to focus the attention of the eligible officers on an important financial indicator of success of the Trust and of other companies in the same business as the Trust.

The performance goal for the Performance Shares to be awarded to a Participant (as defined below) is based on the extent to which the Trust attains the Index-Based Goal (as defined below).

Together with the Plan, this document and the appendices attached hereto constitute the Program.

3.Award Agreement.

(a)Each Participant shall be issued an Award Agreement setting forth the initial number of Base Units awarded to the Participant and entitling the Participant to receive the number of Shares determined under Section 5 based on the extent to which the Index-Based Goal is achieved. The number of Base Units shall be subject to the adjustments described in Section 12 below.

(b)Each Award Agreement and the Shares which may be delivered thereunder are subject to the terms of this Program and the terms of the Plan.

4.No Shareholder Rights. A Participant will not have rights as a shareholder of the Company with respect to the Shares underlying any Base Units issued hereunder unless and until such Shares are actually issued to and held of record by that Participant.

5.Performance Goal.

(a)The number of Shares (if any) deliverable to a Participant with respect to an Award will be equal to (i) the number of Base Units subject to that Award, multiplied by (ii) a percentage determined in accordance with the table below, with reference to the Trust’s TSR for the applicable Measurement Period expressed as a percentile ranking relative to the TSR outcomes of the other component members of the Index for that Measurement Period:

For outcomes between the 25th and 50th percentiles, and the 50th and 75th percentiles, the number of Shares deliverable will be determined by straight line interpolation. Except as provided in Section 9 below, a Participant must be employed by an Employer on the last day of the Measurement Period in order to receive any Shares under this Program. See Appendix A attached hereto for examples illustrating the operation of this Section.

(b)However, notwithstanding the foregoing, if the Trust’s TSR for the applicable Measurement Period is negative, then without regard to the Trust’s percentile ranking relative to the TSR outcomes of the other component members of the Index, the percentage of Base Units deliverable hereunder will be capped at 100%.

(c)Notwithstanding the foregoing, Shares will be delivered under the Program only to the extent that Shares remain available under the Plan; and if the total number of Shares to be delivered as of the end of any Measurement Period exceeds the number of Shares then available under the Plan, the number of Shares deliverable for each Participant will be reduced on a pro rata basis based on each individual Participant’s Base Units as compared to the total of all Participants’ Base Units outstanding with respect to that Measurement Period.

(d)In the case of a Participant who has a separation from service that constitutes a Retirement on or prior to December 31, 2025, the Shares otherwise distributable hereunder will be subject to pro-ration in accordance with Section 9(a), below.

6.Elective Deferrals. Rights granted under the Program shall be treated as “Share Awards” and as “Performance-Based Compensation” as defined in the Brandywine Realty Trust Amended and Restated Deferred Compensation Plan (the “Deferred Compensation Plan”). Accordingly, a Participant may elect to defer receipt of Shares issuable under the Program under the rules of the Deferred Compensation Plan (including any rules established by the administrator of the Deferred Compensation Plan from time to time). Any deferral election agreement shall be in the form prescribed by the Trust.

Notwithstanding any contrary provision of this Program or the Deferred Compensation Plan, the issuance of Shares may be accelerated: (i) to the extent permitted by Treas. Reg. § 1.409A-3(j)(4)(vi) (relating to the satisfaction of tax obligations arising in connection with Awards hereunder), and (ii) to the extent permitted by Treas. Reg. § 1.409A-3(j)(4)(ix)(relating to plan terminations and liquidations).

7.Beneficiary Designation.

(a)Each Participant shall designate the person(s) as the beneficiary(ies) to whom the Participant’s Shares shall be delivered in the event of the Participant’s death prior to the delivery of the Shares to him or her. Each beneficiary designation shall be substantially in the form set forth in Appendix B attached hereto and shall be effective only when filed with the Committee during the Participant’s lifetime.

(b)Any beneficiary designation may be changed by a Participant without the consent of any previously designated beneficiary or any other person by the filing of a new beneficiary designation with the Committee. The filing of a new beneficiary designation shall cancel all beneficiary designations previously filed.

(c)If any Participant fails to designate a beneficiary in the manner provided above, or if the beneficiary designated by a Participant predeceases the Participant, the Committee shall direct such Participant’s Shares to be delivered to the Participant’s surviving spouse or, if the Participant has no surviving spouse, then to the Participant’s estate.

8.Delivery to Guardian. If Shares are issuable under this Program to a minor, a person declared incompetent, or a person incapable of handling the disposition of property, the Committee may direct the delivery of the Shares to the guardian, legal representative, or person having the care and custody of the minor, incompetent or incapable person. The Committee may require proof of incompetence, minority, incapacity or guardianship as the Committee may deem appropriate prior to the delivery. The delivery shall completely discharge the Committee, the Trustees and the Employer from all liability with respect to the Shares delivered.

9.Termination of Employment. Upon a Participant’s termination of employment on or prior to the last day of the Measurement Period, the following shall occur:

(a)Termination on Account of Retirement, Disability or Death. If, on or prior to December 31, 2025 (i) the Participant has a separation from service that constitutes a Retirement, (ii) the Participant incurs a Disability Termination, or (iii) the Participant dies, then the Participant (or the Participant’s beneficiary(ies), if applicable) shall be eligible to receive Shares (if any) under the Program as if the Measurement Period ended on the last day of the month in which the Retirement, termination or death occurred and as though the Participant had remained employed by the Employer through such date. However, in the case of a Participant who has a separation from service that constitutes a Retirement on or prior to December 31, 2025, the Shares otherwise distributable hereunder will be subject to proration. The proration will be performed by multiplying the Shares otherwise distributable hereunder by a fraction, the numerator of which will be the number of calendar months that have ended since the Grant Date and prior to the Participant’s separation from service, and the denominator of which will be 35. Any Shares not distributable due to the foregoing proration will be forfeited. For avoidance of doubt, the provisions of this paragraph apply in lieu of Section 9(b)(iii) of the Plan.

(b)Termination for Any Other Reason. If, on or prior to December 31, 2025, the Participant’s employment with the Employer terminates for any reason other than a reason described in paragraph (a) of this Section 9, the Participant shall forfeit all of the Base Units and any other rights under the Program.

10.Determination of Performance; Share Delivery. Within 30 days after the end of the Measurement Period, the Committee shall provide each Participant (or his or her beneficiary, if applicable) with a written determination of whether the Trust did or did not attain the Index-Based Goal for the applicable Measurement Period (and, if applicable, the extent to which the Index-Based Goal was attained) and the calculations used to make such determination. If Shares are to be delivered under the Program, unless a Participant validly elects otherwise pursuant to Section 6 above, they shall be delivered on February 1, 2026 or, if a Change of Control occurs before January 1, 2026, on the fifth day after the Change of Control or, in the case of a separation from service described in Section 9(a) above, on or before the thirtieth day after that separation from service.

11.Source of Shares. This Program shall be unfunded, and the delivery of Shares shall be pursuant to the Plan. Each Participant and beneficiary shall be a general and unsecured creditor of the Employer to the extent of the Shares determined hereunder, and the Participant shall have no right, title or interest in any specific asset that the Employer may set aside, earmark or identify as reserved for the delivery of Shares under the Program. The Employer’s obligation under the Program shall be merely that of an unfunded and unsecured promise to deliver Shares in the future, provided the applicable service condition is satisfied and the Index-Based Goal is met.

12.Capital Adjustments. Calculations required under the Program, the number of Base Units awarded under the Program, and the number of Shares that may be delivered under the Program shall be adjusted to reflect any increase or decrease in the number of issued Shares resulting from a subdivision (share-split), consolidation (reverse split), share dividend, or other change in the capitalization of the Trust during the Measurement Period.

13.Tax Withholding; Securities Law Compliance. The delivery of Shares (and cash, if applicable) to a Participant or beneficiary under this Program shall be subject to applicable tax withholding pursuant to the Plan. The delivery of Shares to a Participant or beneficiary under this Program and the resale of any such Shares shall be subject to applicable compliance with applicable federal and state securities laws.

14.Administration. The Program shall be administered by the Committee pursuant to the powers granted to it in Section 2 of the Plan.

15.Clawback. Performance Shares and rights under an Award Agreement shall be subject to all applicable current and future laws, regulations and stock exchange listing requirements, including laws, regulations and requirements that require recovery by the Trust of incentive-based compensation in the event of material non-compliance with any financial reporting requirements under federal securities laws.

16.Amendment and Termination. The Committee reserves the right to amend the Program, by written resolution, at any time and from time to time in any fashion, provided any such amendment does not conflict with the terms of the Plan, and to terminate it at will. However, no amendment or termination of the Program shall adversely affect any Award Agreement already issued under the Program without the written consent of the affected Participant(s).

17.Headings. The headings of the Sections and subsections of the Program are for reference only. In the event of a conflict between a heading and the content of a Section or subsection, the content of the Section or subsection shall control.

18.Section 409A. To the extent applicable, this Program is intended to comply with Section 409A of the Code and will be interpreted accordingly. Section 9(b)(v) of the Plan will only be applicable to the delivery of Shares under the Program to the extent permissible under Section 409A of the Code. The determination of whether and when Grantee’s separation from service has occurred will be made in a manner consistent with, and based on the presumptions set forth in, Treas. Reg. § 1.409A-1(h). Solely for this purpose, “Employer” will include all persons with whom the Trust would be considered a single employer as determined under Treas. Reg. § 1.409A-1(h)(3). To the extent compliance with the requirements of Treas. Reg. § 1.409A-3(i)(2) (relating to “specified employees”) is necessary to avoid the application of an additional tax under Section 409A to payments due to a Participant upon his or her separation from service, then notwithstanding any other provision of this Program, the Plan or the Deferred Compensation Plan, the issuance of Shares will be delayed until the earlier of (i) six months and one day following that Participant’s separation from service, or (ii) that Participant’s death.

19.Incorporation of Plan by Reference. Because the Program is established under the Plan in order to provide for, and determine the terms and conditions of, the granting of certain awards thereunder, the terms and conditions of the Plan are hereby incorporated by reference and made a part of this Program. Unless otherwise expressly stated herein, if any terms of the Program conflict with the terms of the Plan, the terms of the Plan shall control.
