Ladies and Gentlemen:

From time to time Brandywine Realty Trust, a Maryland real estate investment trust (the “Company”), and Brandywine Operating Partnership, L.P., a Delaware limited partnership and a subsidiary of the Company (the “Operating Partnership”), may enter into one or more Pricing Agreements (each a “Pricing Agreement”) in the form of Annex I hereto, with such additions and deletions as the parties thereto may determine, and, subject to the terms and conditions stated herein and therein, for the Company to issue and sell to Merrill Lynch, Pierce, Fenner & Smith Incorporated and Citigroup Global Markets Inc. (such firms constituting the “Underwriters” with respect to such Pricing Agreement and the securities specified therein) certain of its common shares of beneficial interest, par value $0.01 per share (the “Common Shares”) specified in Schedule I to such Pricing Agreement (with respect to such Pricing Agreement, the “Firm Shares”). If specified in such Pricing Agreement, the Company may grant to the Underwriters the right to purchase at their election an additional number of Common Shares specified in such Pricing Agreement as provided in Section 3 hereof (the “Optional Shares”). The Firm Shares and the Optional Shares, if any, which the Underwriters elect to purchase pursuant to Section 3 hereof are herein collectively called the “Designated Shares”).

The terms and conditions of any particular issuance of Designated Shares will be as specified in the Pricing Agreement relating thereto.

1. Introduction. Particular sales of Designated Shares may be made from time to time to the Underwriters of such Designated Shares. This Underwriting Agreement (the “Agreement”) will not be construed as an obligation of the Company to offer, issue or sell any of the Common Shares or as an obligation of any of the Underwriters to purchase the Common Shares. The obligation of the Company to issue and sell any of the Common Shares and the obligation of any of the Underwriters to purchase any of the Common Shares will be evidenced by the Pricing Agreement with respect to the Designated Shares specified therein. Each Pricing

Agreement will, among other things, specify the aggregate number of Firm Shares, the maximum number of Optional Shares, if any, the manner of determining the initial public offering price of such Firm Shares and Optional Shares, the purchase price to the Underwriters of such Designated Shares, the names of the Underwriters of such Designated Shares, the number of such Designated Shares to be purchased by each Underwriter, and the underwriting discount and commission, if any, payable to the Underwriters with respect thereto and will set forth the date, time and manner of delivery of such Firm Shares and Optional Shares, if any, and payment therefor. The Pricing Agreement will also specify (to the extent not set forth in the registration statement and prospectus with respect thereto) the terms and conditions of such Designated Shares. The Pricing Agreement shall be in the form of an executed writing (which may be in counterparts), and may be evidenced by an exchange of facsimile communications or any other rapid transmission device designed to produce a written record of communications transmitted. The obligations of the Underwriters under this Agreement and each Pricing Agreement will be several and not joint.

2. Representations, Warranties and Agreements of the Company. The Company and the Operating Partnership, jointly and severally, represent and warrant to, and agree with, each of the Underwriters as follows:

(a) A registration statement on Form S-3 (File No. 333-174700) in respect of the Common Shares has been (i) prepared by the Company and the Operating Partnership in conformity with the requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations of the Securities and Exchange Commission (the “Commission”) thereunder, and (ii) filed with the Commission under the Securities Act and declared effective by the Commission; no stop order suspending the effectiveness of the registration statement or any post-effective amendment thereto, has been issued, and no proceeding for that purpose or pursuant to Section 8A of the Securities Act has been initiated or threatened by the Commission; and the Company proposes to file with the Commission pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”) a prospectus supplement to the form of prospectus included in such registration statement and has previously advised you of all information (financial and other) with respect to the Company to be set forth therein.

(dd) No subsidiary of the Company (including, without limitation, the Operating Partnership) is currently prohibited, directly or indirectly, from paying any dividends to the Company, from making any other distribution on such subsidiary’s capital stock or other equity, from repaying to the Company any loans or advances to such subsidiary from the Company, or from transferring any of such subsidiary’s property or assets to the Company or any other subsidiary of the Company, except that, in the case of subsidiaries of the Company set forth on Schedule III to the applicable Pricing Agreement that are joint ventures, the relevant joint venture agreements require the consent of their respective joint venture partners as a condition to making such payments or transfers and that following an event of default under the loan documents encumbering the properties owned by a subsidiary of the Company (including, without limitation, the Operating Partnership) such subsidiary may be prohibited from making distributions to the Company.

(ee) The statistical and market-related data, if any, included in the Time of Sale Information and the Prospectus is based on or derived from sources which the Company believes, in good faith, to be reliable and accurate in all material respects.

(ff) The Company has not taken nor will it take, directly or indirectly any action designed to, or that might reasonably be expected to, cause or result in manipulation of the price of the Common Shares.

For purposes of this Section 2, references to “subsidiaries”, insofar as such references relate to entities in which the Company or Operating Partnership own or hold an equity or equivalent interest equal to or less than 50%, are made by the Company and Operating Partnership to their knowledge (after due inquiry).

3. Offer and Sale of the Designated Shares. Upon the execution of the Pricing Agreement applicable to any Designated Shares and authorization by the Underwriters of the release of the Firm Shares, the several Underwriters propose to offer the Firm Shares and Optional Shares, if any, for sale upon the terms and conditions set forth in the Prospectus.

The Company may specify in the Pricing Agreement applicable to any Designated Shares that the Company thereby grants to the Underwriters the right (an “Option”) to purchase at their election up to the number of Optional Shares set forth in such Pricing Agreement, on the terms set forth in the paragraph above. Any such election to purchase Optional Shares may be exercised in whole or in part by written notice from the Underwriters to the Company, given at any time within a period specified in the Pricing Agreement, setting forth the aggregate number of Optional Shares to be purchased and the date on which such Optional Shares are to be delivered, as determined by the Underwriters.

The number of Optional Shares to be added to the number of Firm Shares to be purchased by each Underwriter as set forth in Schedule I to the Pricing Agreement applicable to such Designated Shares will be, in each case, the number of Optional Shares which the Company has been advised by the Underwriters have been attributed to such Underwriter; provided that, if the

Company has not been so advised, the number of Optional Shares to be so added will be, in each case, that proportion of Optional Shares which the number of Firm Shares to be purchased by such Underwriter under such Pricing Agreement bears to the aggregate number of Firm Shares (rounded as the Underwriters may determine to the nearest 100 shares). The total number of Designated Shares to be purchased by all the Underwriters pursuant to such Pricing Agreement will be the aggregate number of Firm Shares set forth in Schedule I to such Pricing Agreement plus the aggregate number of Optional Shares which the Underwriters elect to purchase.

4. Delivery of the Firm Shares and the Optional Shares. Designated Shares to be purchased by each Underwriter pursuant to the Pricing Agreement relating thereto, in the form specified in such Pricing Agreement, and in such authorized denominations and registered in such names as the Underwriters may request upon at least 24 hours’ prior notice to the Company, will be delivered by or on behalf of the Company to the Underwriters for the account of such Underwriters, against payment by such Underwriters or on their behalf of the purchase price therefor by wire transfer in federal or other same day funds, payable to the order of the Company in the funds specified in such Pricing Agreement, (i) with respect to the Firm Shares all in the manner and at the place and time and date specified in such Pricing Agreement or at such other place and time and date as the Underwriters and the Company may agree upon in writing, such time and date being herein called the “First Time of Delivery” and (ii) with respect to the Optional Shares, if any, in the manner and at the time and date specified pursuant to the applicable Pricing Agreement by the Underwriters in the written notice given by the Underwriters of the Underwriters’ election to purchase such Optional Shares, or at such other time and date as the Underwriters and the Company may agree upon in writing, such time and date, if not the First Time of Delivery, herein called a “Subsequent Time of Delivery”. Each such time and date for delivery is herein called a “Time of Delivery”.

5. Further Agreements of the Company. The Company agrees with each of the Underwriters of any Designated Shares as follows:

(a) To prepare the Prospectus in relation to the applicable Designated Shares in a form approved by the Underwriters and to file such Prospectus pursuant to Rule 424(b) under the Securities Act no later than the Commission’s close of business on the second business day following the execution and delivery of the Pricing Agreement relating to the applicable Designated Shares or, if applicable, such earlier time as may be required by Rule 424(b); to file any Issuer Free Writing Prospectus to the extent and within the time period, required by Rule 433 under the Securities Act; to make no further amendment or any supplement to the Registration Statement or Prospectus after the Time of Sale and prior to any Time of Delivery for such Designated Shares which shall be disapproved by the Underwriters for such Designated Shares promptly after reasonable notice thereof; not to use, authorize, approve, refer to or file any Issuer Free Writing Prospectus which shall be disapproved by the Underwriters for such Designated Shares promptly after reasonable notice thereof; to advise the Underwriters promptly of any amendment or supplement to the Registration Statement or the Prospectus after any Time of Delivery for such Designated Shares and furnish the Underwriters with copies thereof; to file promptly all reports and any definitive proxy or information statements required to be filed by the Company or the Operating Partnership with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act for so long as the delivery of a prospectus is required in connection with the offering or sale of such Designated Shares; and during such same period to

(f) To make generally available to its security holders as soon as practicable, but in any event not later than eighteen months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), an earnings statement of the Company and its consolidated subsidiaries (including, without limitation, the Operating Partnership)(which need not be audited) complying with Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder (including, at the option of the Company, Rule 158);

(g) To apply the net proceeds from the sale of the Designated Shares as described in the Preliminary Prospectus and the Prospectus;

(h) Not to take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation, which is contrary to any applicable law, of the price of any security of the Company or the Operating Partnership to facilitate the sale or resale of the Common Shares;

(i) Not to be or become, at any time prior to the expiration of three years after any Time of Delivery, an “investment company” or an entity “controlled” by an “investment company” (as such terms are defined in the Investment Company Act);

(k) To retain, pursuant to reasonable procedures developed in good faith, copies of each Issuer Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company and the Operating Partnership and their respective trustees, officers and employees and each person, if any, who controls the Company or Operating Partnership within the meaning of the Securities Act or the Exchange Act against any losses, claims, damages or liabilities to which the Company, the Operating Partnership or any of their respective trustees, officers, employees or controlling persons may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus

relating to the Designated Shares, or any amendment or supplement thereto, the Time of Sale Information, or any Issuer Free Writing Prospectus or (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in any preliminary prospectus, the Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Shares, or any such amendment or supplement, the Time of Sale Information, or any Issuer Free Writing Prospectus, in reliance upon and in conformity with written information furnished to the Company or Operating Partnership by such Underwriter expressly for use therein, and will reimburse the Company or the Operating Partnership for any legal or other expenses reasonably incurred by the Company or Operating Partnership in connection with investigating or defending any such action or claim as such expenses are incurred.

(c) Promptly after receipt by an indemnified party under Section 9(a) or 9(b) above of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under such Section. In case any such action will be brought against any indemnified party and it will notify the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it will wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who will not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under such Section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation; provided, however, that any indemnified party will have the right to employ separate counsel in any such action and to participate in the defense thereof but the fees and expenses of such counsel will be at the expense of such indemnified party unless (i) the employment thereof has been specifically authorized by the indemnifying party in writing, (ii) such indemnified party will have been advised by such counsel that there may be one or more legal defenses available to it which are different from or additional to those available to the indemnifying party and in the reasonable judgment of such counsel it is advisable for such indemnified party to employ separate counsel or (iii) the indemnifying party has failed to assume the defense of such action and employ counsel reasonably satisfactory to the indemnified party, in which case, if such indemnified party notifies the indemnifying party in writing that it elects to employ separate counsel at the expense of the indemnifying party, the indemnifying party will not have the right to assume the defense of such action on behalf of such indemnified party, it being understood, however, that the indemnifying party will not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate counsel (plus local counsel in each such jurisdiction) at any time for all such indemnified parties. If the indemnifying party does not assume the defense of such action, it is understood that the indemnifying party will not, in connection with any one such action or

separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate counsel (plus local counsel in each such jurisdiction) at any time for all such indemnified parties, which firms will be designated in writing by the Underwriters, if the indemnified parties under this Section 9 consist of any Underwriter of the Designated Shares or any of its respective directors, officers, employees, selling agents, controlling persons or affiliates, or by the Company and the Operating Partnership, if the indemnified parties under this Section 9 consist of the Company or the Operating Partnership, or any of their respective trustees, officers or controlling persons. The indemnifying party will not be liable for any settlement of an action or claim for monetary damages which an indemnified party may effect without the consent of the indemnifying party, which consent will not be unreasonably withheld. No indemnifying party will, without the written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim), unless such settlement, compromise or judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include a statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party. For purposes of this Section 9, references to “counsel” will include a firm of attorneys.

(d) If the indemnification provided for in this Section 9 is unavailable to or insufficient to hold harmless an indemnified party under Section 9(a) or 9(b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party will contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Operating Partnership on the one hand and the Underwriters of the Designated Shares on the other from the offering of the Designated Shares to which such loss, claim, damage or liability (or action in respect thereof) relates. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 9(c) above, then each indemnifying party will contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits referred to in the immediately preceding sentence but also the relative fault of the Company and the Operating Partnership on the one hand and the Underwriters of the Designated Shares on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative benefits received by the Company and the Operating Partnership on the one hand and such Underwriters on the other will be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total commissions or discounts received by such Underwriters in respect thereof. The relative fault will be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading relates to information supplied by the Company or the Operating Partnership on the one hand or by any such Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to

correct or prevent such statement or omission. The Company, the Operating Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 9(d) were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 9(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section 9(d) will be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 9(d), no Underwriter will be required to contribute any amount in excess of the amount by which the total public offering price at which the applicable Designated Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The obligations of the Underwriters of Designated Shares in this Section 9(d) to contribute are several in proportion to their respective underwriting obligations with respect to such Designated Shares and not joint.

(e) The obligations of the Company and the Operating Partnership under this Section 9 will be in addition to any liability which the Company and Operating Partnership may otherwise have and will extend, upon the same terms and conditions, to each director, officer, employee and selling agent of any Underwriter, to each person, if any, who controls any Underwriter within the meaning of the Securities Act or the Exchange Act, and to each affiliate of any Underwriter; and the obligations of the Underwriters under this Section 9 will be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each of the respective trustees, officers and employees of the Company and the Operating Partnership and to each person, if any, who controls the Company or Operating Partnership within the meaning of the Securities Act or the Exchange Act.

10. Defaulting Underwriters. (a) If any Underwriter shall default in its obligation to purchase the Firm Shares or Optional Shares which it has agreed to purchase under the Pricing Agreement relating to such Designated Shares, the remaining non-defaulting Underwriter may in its discretion arrange for itself or another party or other parties to purchase such Designated Shares on the terms contained herein. If within 36 hours after such default by any Underwriter the remaining non-defaulting Underwriter does not arrange for the purchase of such Firm Shares or Optional Shares, as the case may be, then the Company shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to the remaining non-defaulting Underwriter to purchase such Designated Shares on such terms. In the event that, within the respective prescribed period, the remaining non-defaulting Underwriter notifies the Company that it has so arranged for the purchase of such Designated Shares, or the Company notifies the remaining non-defaulting Underwriter that it has so arranged for the purchase of such Designated Shares, the non-defaulting Underwriter or the Company shall have the right to postpone a Time of Delivery for such Designated Shares for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the

Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the non-defaulting Underwriter may thereby be made necessary. The term “Underwriter” as used in this Agreement will include any person substituted under this Section with like effect as if such person had originally been a party to the Pricing Agreement with respect to such Designated Shares.

(b) If, after giving effect to any arrangements for the purchase of the Firm Shares or Optional Shares, as the case may be, of a defaulting Underwriter or Underwriters by the non-defaulting Underwriter and the Company as provided in Section 10(a) above, the aggregate number of such Common Shares, which remains unpurchased does not exceed one-eleventh of the number of the Firm Shares or Optional Shares, as the case may be, to be purchased at the respective Time of Delivery then the Company will have the right to require the remaining non-defaulting Underwriter to purchase the number of Firm Shares or Optional Shares, as the case may be, which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Shares and, in addition, to require such non-defaulting Underwriter to purchase its pro-rata share (based on the number of Firm Shares or Optional Shares, as the case may be, which such Underwriter agreed to purchase under such Pricing Agreement) of the Firm Shares or Optional Shares, as the case may be, of such defaulting Underwriter for which such arrangements have not been made; but nothing herein will relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Firm Shares or Optional Shares, as the case may be, of a defaulting Underwriter or by the non-defaulting Underwriter and the Company as provided in Section 10(a) above, the aggregate number of Firm Shares or Optional Shares, as the case may be, which remains unpurchased exceeds one-eleventh of the aggregate number of the Firm Shares or Optional Shares, as the case may be, to be purchased at the respective Time of Delivery as referred to in Section 10(b) above, or if the Company will not exercise the right described in Section 10(b) above to require the remaining non-defaulting Underwriter to purchase the Firm Shares or Optional Shares, as the case may be, of the defaulting Underwriter, then the Pricing Agreement relating to such Firm Shares or the Option related to the Optional Shares, as the case may be, shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein will relieve a defaulting Underwriter from liability for its default.

11. Survival. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Operating Partnership and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, will remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any director, officer or employee, controlling person or affiliate of any Underwriter, or the Company or the Operating Partnership, or any trustee, officer or employee or controlling person of the Company or the Operating Partnership, and will survive delivery of and payment for the Designated Shares.

12. Termination. If any Pricing Agreement will be terminated pursuant to Section 10 hereof or if any condition in Section 8(g)(i), 8(g)(iii) or 8(g)(iv) hereof is not satisfied, the

Company shall not then be under any liability to any Underwriter with respect to the Designated Shares covered by such Pricing Agreement except as provided in Sections 7 and 9 hereof, but, if for any other reason, Designated Shares are not delivered by or on behalf of the Company as provided herein, the Company shall reimburse the Underwriters for all out-of-pocket expenses approved in writing by the Underwriters, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Shares, but the Company will then be under no further liability to any Underwriter with respect to such Designated Shares except as provided in Sections 7 and 9 hereof.

13. Notices. All statements, requests, notices and agreements hereunder will be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the address of the Underwriters as set forth in the Pricing Agreement; and if to the Company or the Operating Partnership shall be delivered or sent by mail, telex or facsimile transmission to the address of the Company set forth in the Registration Statement, Attention: General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 9(c) hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its underwriters’ questionnaire, or telex constituting such questionnaire, which address will be supplied to the Company and the Operating Partnership by the Underwriters upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

14. Nature of Underwriters’ Obligations. The Company and the Operating Partnership acknowledge and agree that (i) the purchase and sale of the Designated Shares pursuant to this Agreement and the applicable Pricing Agreement is an arm’s-length commercial transaction between the Company, on the one hand, and the several Underwriters, on the other, (ii) in connection therewith and with the process leading to such transaction, each Underwriter is acting solely as a principal and not the agent or fiduciary of the Company or the Operating Partnership, (iii) no Underwriter has assumed an advisory or fiduciary responsibility in favor of the Company or the Operating Partnership with respect to the offering of the Designated Shares or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Operating Partnership on other matters) or any other obligation to the Company or the Operating Partnership except the obligations expressly set forth in this Agreement and the applicable Pricing Agreement and (iv) the Company and the Operating Partnership have consulted their own legal and financial advisors to the extent they deemed it appropriate. The Company and the Operating Partnership agree that they shall not claim that the Underwriters, or any of them, owes an advisory, fiduciary or similar duty to the Company in connection with such transaction or the process leading thereto.

15. Persons Entitled to Benefit of Agreement. This Agreement and each Pricing Agreement will be binding upon, and inure solely to the benefit of, the Underwriters, the Company and the Operating Partnership and, to the extent provided in Sections 9 and 11 hereof, the trustees, officers and employees of the Company or the Operating Partnership or the directors, officers, selling agents and employees of any Underwriter, each person who controls the Company, the Operating Partnership or any Underwriter, and the affiliates of any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person will acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the Designated Shares from any Underwriter will be deemed a successor or assign by reason merely of such purchase.

16. Time of Essence. Time shall be of the essence of each Pricing Agreement. As used herein, “business day” means any day on which the New York Stock Exchange, Inc. is open for trading.

17. Governing Law. THIS AGREEMENT AND EACH PRICING AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

18. Counterparts. This Agreement and each Pricing Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts will together constitute one and the same instrument.

Citigroup Global Markets Inc.

Ladies and Gentlemen:

Brandywine Realty Trust, a Maryland real estate investment trust (the “Company”), and Brandywine Operating Partnership, L.P., a Delaware limited partnership and subsidiary of the Company (the “Operating Partnership”), proposes, subject to the terms and conditions stated herein and in the Underwriting Agreement, dated April 4, 2013 (the “Underwriting Agreement”), among the Company, the Operating Partnership and you for the Company to issue and sell to the Underwriters named in Schedule I hereto (the “Underwriters”) the common shares of beneficial interests of the Company specified in Schedule I hereto (the “Designated Shares”, consisting of Firm Shares and any Optional Shares the Underwriters may elect to purchase). Each of the provisions of the Underwriting Agreement is incorporated herein by reference in its entirety, and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein, and each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Pricing Agreement, except that each representation and warranty which refers to the Preliminary Prospectus and the Prospectus in Section 2 of the Underwriting Agreement shall be deemed to be a representation or warranty as of the date of the Underwriting Agreement in relation to the Preliminary Prospectus and the Prospectus, and also a representation and warranty as of the date of this Pricing Agreement in relation to the Preliminary Prospectus and the Prospectus relating to the Designated Shares which are the subject of this Pricing Agreement. Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein as therein defined.

The Prospectus, relating to the Designated Shares, in the form of the draft heretofore delivered to you, is now proposed to be filed with the Commission.

Subject to the terms and conditions set forth herein and in the Underwriting Agreement incorporated herein by reference, (a) the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees, severally and not jointly, to purchase from the Company, at the time and place and at the purchase price to the Underwriters set forth in Schedule I hereto, the number of Firm Shares set forth in Schedule I hereto and (b) in the event and to the extent that the Underwriters shall exercise the election to purchase Optional Shares, as provided below, the Company agrees to issue and sell to each of the Underwriters, and each of the Underwriters agrees to purchase from the Company at the purchase price to the Underwriters set forth in Schedule I hereto that portion of the number of Optional Shares as to which such election shall have been exercise. The Company hereby grants to each of the

ANNEX I-1

Underwriters the right to purchase, from time to time, at its election up to the number of Optional Shares set forth in Schedule I hereto on the terms referred to in the paragraph above. Any such election to purchase Optional Shares may be exercised by written notice from the Underwriters to the Company given within a period of 30 calendar days after the date of this Pricing Agreement, setting forth the aggregate number of Optional Shares to be purchased and the date on which such Optional Shares are to be delivered, as determined by the Underwriters, but in no event earlier than the First Time of Delivery or, unless the Underwriters and the Company otherwise agree in writing, no earlier than two or later than ten business days after the date of such notice.

If the foregoing is in accordance with your understanding, please sign and return to us four counterparts hereof, and upon acceptance hereof by you, on behalf of each of the Underwriters, this letter and such acceptance hereof, including the provisions of the Underwriting Agreement incorporated herein by reference, shall constitute a binding agreement among the Company, the Operating Partnership and the Underwriters.

ANNEX II

FORM OF OPINION OF PEPPER HAMILTON LLP, COUNSEL TO THE

COMPANY

The Company has been duly formed and is validly existing as a real estate investment trust in good standing under the laws of the State of Maryland, with trust power and authority to own its properties and conduct its business as described in the Time of Sale Information and the Prospectus.

The Operating Partnership has been duly formed and is validly existing as a limited partnership in good standing under the laws of the State of Delaware, with limited partnership power and authority to own its properties and conduct its business as described in the Time of Sale Information and the Prospectus; the units of partnership interest in the Operating Partnership (“Units”) owned by the Company have been duly and validly authorized and have been duly and validly issued and are fully paid and free of any preemptive or other rights afforded by the Operating Partnership to subscribe for or purchase Units under applicable law or any agreement known to us; and the Units issuable to the Company in exchange for the contribution by the Company to the Operating Partnership of the net proceeds from the issuance and sale of the Designated Shares will, when such Units are issued and delivered as described in the Time of Sale Information and the Prospectus, be duly and validly issued and fully paid and free of any preemptive or other rights afforded by the Operating Partnership to subscribe for or purchase Units under applicable law or any agreement known to us.

Each other subsidiary (in addition to the Operating Partnership) listed Schedule I to this opinion, which constitute, the Company’s “significant subsidiaries” (as defined in Rule 405 under the Securities Act) (together with the Operating Partnership, the “Significant Subsidiaries”), has been duly incorporated, formed or organized and is validly existing as a corporation or other entity in good standing under the laws of its jurisdiction of incorporation, formation or organization, with corporate, trust, limited liability company or partnership power and authority to own its properties and conduct its business as described in the Time of Sale Information and the Prospectus; and all of the issued shares of capital stock, limited liability company interests, partnership interests or beneficial interests, as applicable, of each of the Significant Subsidiaries have been duly and validly authorized and issued, are fully paid and, as applicable, non-assessable. We have no reason to believe that the Company has any other “significant subsidiaries” other than those listed on Schedule I to this opinion.

All of the issued beneficial interests of the Company have been duly and validly authorized and issued and are fully paid; and the Company is the sole general partner of the Operating Partnership and its percentage interest and ownership in the Operating Partnership is as set forth in the Time of Sale Information and the Prospectus as of the dates indicated therein.

Annex II-1

(A) The Company has been duly qualified or registered as a foreign trust for the transaction of business and is in good standing or subsisting under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification or registration, except where the failure to so qualify or register or be in good standing or subsisting could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect; (B) the Operating Partnership has been duly qualified or registered as a foreign partnership for the transaction of business and is in good standing or subsisting under the laws of each other jurisdiction in which it owns or leases properties, or conducts any business so as to require such qualification or registration, except where the failure to so qualify or register or be in good standing or subsisting could not reasonably be expected, individually or in the aggregate to have a Material Adverse Effect; and (C) each other Significant Subsidiary has been duly qualified or registered as a foreign corporation or other entity for the transaction of business and is in good standing or subsisting under the laws of each other jurisdiction in which it owns or leases properties or conducts any business so as to require such qualification or registration, except where the failure to so qualify or register or be in good standing or subsisting could not reasonably be expected, individually or in the aggregate, to have a Material Adverse Effect.

The Designated Shares have been duly and validly authorized, and, when such Designated Shares are issued and delivered against payment therefor pursuant to the Underwriting Agreement, such Designated Shares will be duly and validly issued and fully paid; the Common Shares conform, in all material respects, to the description thereof contained in the Time of Sale Information, and the Designated Shares will conform, in all material respects, to the description thereof in the Time of Sale Information and the Prospectus; the Designated Shares will have the rights set forth in the Company’s declaration of trust and by-laws, each as then amended or supplemented (including the applicable provisions of the laws of Maryland governing real estate investment trusts); and there are no preemptive or other rights afforded by the Company to subscribe for or to purchase any Common Shares under applicable law or any agreement known to us.

To our knowledge and except as set forth in the Time of Sale Information and the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) is a party, or of which any property of the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) is the subject, which are required, individually or in the aggregate, to be disclosed in the Registration Statement, the Time of Sale Information or the Prospectus which are not fairly described therein as required; and, to our knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others.

The Underwriting Agreement has been duly authorized, executed and delivered by the Company and the Operating Partnership.

Except as otherwise addressed in the paragraph immediately following the opinions expressed in paragraph 16, the issuance and sale of the Designated Shares being delivered

Annex II-2

at such Time of Delivery, the compliance by the Company and the Operating Partnership with all of the provisions of the Underwriting Agreement and the consummation of the transactions herein and therein contemplated do not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument known to us to which the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) is a party or by which the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) is bound or to which any of the property or assets of the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) is subject, nor do such actions result in any violation of the provisions of the declaration of trust or the by-laws of the Company or the limited partnership agreement of the Operating Partnership, or any statute or any order, rule or regulation known to us of any court or governmental agency or body of the State of Delaware, Maryland or New York, the Commonwealth of Pennsylvania or the United States of America, in each case, having jurisdiction over the Company or any of its subsidiaries (including, without limitation, the Operating Partnership) or any of their properties.

10.

No consent, approval, authorization, order, registration or qualification of or with any court or governmental agency or body is required for the issuance and sale of the Designated Shares being delivered at such Time of Delivery, or the consummation by the Company or the Operating Partnership of the other transactions contemplated by the Underwriting Agreement, except such as have been obtained under the Securities Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Designated Shares by the Underwriters (as to which we express no opinion).

11.

The Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus included in the Time of Sale Information and the Prospectus and any amendments and supplements thereto made by the Company prior to the Time of Delivery for the Designated Shares (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no opinion) comply as to form in all material respects with the requirements of the Securities Act and the rules and regulations thereunder.

12.

The Incorporated Documents (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no opinion), when they were filed with the Commission or became effective, as the case may be, complied as to form in all material respects with the requirements of the Exchange Act or the Securities Act, as applicable, and the rules and regulations of the Commission thereunder; and we have no reason to believe that any of the Incorporated Documents, when they were so filed or became effective, as the case may be, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no opinion).

Annex II-3

13.

Neither the Company nor the Operating Partnership is, or upon the issuance and sale of the Designated Shares and the application of the net proceeds therefrom as described in the Time of Sale Information and the Prospectus will be, an “investment company” within the meaning of the Investment Company of 1940, as amended.

14.

The statements made under the caption under “Material United States Federal Income Tax Consequences” in the Time of Sale Information and the Prospectus, insofar as they purport to constitute summaries of matters of U.S. federal tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects.

15.

Commencing with its taxable year ended December 31, 1986, the Company has, since the effective date of its REIT election, been organized and operated in a manner so as to qualify for taxation as a REIT under the Internal Revenue Code of 1986, as amended, and the Company’s proposed method of operation will enable it to continue to qualify for taxation as a REIT.

16.

The Registration Statement has become effective under the Securities Act; the Preliminary Prospectus and the Prospectus relating to the Designated Shares were filed with the Commission within the prescribed time periods pursuant to Rule 424(b)(5) of the rules and regulations under the Securities Act; any Issuer Free Writing Prospectus relating to the Designated Shares was filed with the Commission within the prescribed time periods pursuant to Rule 433 under the Securities Act; and, to our knowledge, no stop order suspending the effectiveness of the Registration Statements has been issued or proceeding for that purpose or pursuant to Section 8A of the Securities Act has been instituted or threatened by the Commission.

We advise you that because the primary purpose of our engagement was not to establish or confirm factual matters or financial or accounting matters, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus included in the Time of Sale Information or the Prospectus or any amendments thereto (other than to the extent expressly set forth under paragraphs 6 and 14 above). Without limiting the foregoing, we assume no responsibility for and have not independently verified the accuracy, completeness or fairness of the financial statements and related notes and schedules and other financial data included in the Registration Statement or Prospectus or any amendments thereto and have not examined the accounting or financial records from which such financial statements, notes, schedules and other financial data are derived. In connection with our engagement, we have participated in conferences with officers and other representatives of the Company, representatives of the independent public accountants of the Company, you and your counsel and representatives of the Underwriters at which the contents of the Registration Statement, the Time of Sale Information, the Prospectus and any amendments thereto were discussed and have also reviewed certain documents and records of the Company and the Operating Partnership. Based upon such participation, discussions and reviews, we have no reason to believe that (A) as of their respective effective dates, the Registration Statement or any amendment thereto made by the Company prior to any Time of Delivery (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no belief) contained an

Annex II-4

untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading, (B) as of the Time of Sale (which we assume shall be the date of the Pricing Agreement), the Time of Sale Information (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no belief) contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading, or (C) as of its date and as of the Time of Delivery, the Prospectus or any amendment or prospectus supplement thereto made by the Company prior to the Time of Delivery (other than the financial statements and related notes and schedules and other financial data therein, as to which we express no belief) contained or contains an untrue statement of a material fact or omitted or omits to state a material fact necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; and we do not know of any amendment to the Registration Statement required to be filed or any contracts or other documents of a character required to be filed as an exhibit to the Registration Statement or required to be incorporated by reference into the Registration Statement, the Preliminary Prospectus or the Prospectus or required to be described in the Registration Statement, the Preliminary Prospectus or the Prospectus that are not filed or incorporated by reference or described as required.

The foregoing paragraph shall not apply to (a) offers, sales, gifts, assignments or transfers of Common Shares or options to purchase Common Shares made to (i) members of the immediate family of the undersigned, (ii) corporations, partnerships, limited liability companies or other entities to the extent such entities are wholly owned by the undersigned and/or members of the immediate family of the undersigned, (iii) shareholders, partners or members of the entities to which Common Shares or options to purchase Common Shares were transferred under clause (ii); or (iv) charitable organizations; (b) transfers of Common Shares or options to purchase Common Shares made to any trust for the direct or indirect benefit of the undersigned or any party listed in clause (a) promptly above; (c) offers, sales or other transfers of Common Shares or options to purchase Common Shares pursuant to an existing trading plan meeting the requirements of Rule 10b5-1 under the Securities Exchange Act of 1934 as amended (the “Exchange Act”), and (d) sales, assignments or other transfers to the Company of capital shares or cancellation of capital shares in payment of applicable taxes payable in connection with the vesting of outstanding equity incentive awards; provided, however that (A) in the case of clauses (a) or (b) above, each recipient or trustee of a trust agrees to be bound by identical restrictions, including the lock-up period set forth herein, (B) for transfers by will, interstate succession or pursuant to a trust, any report required to be filed under the Exchange Act will state the reason for the transfer and that the transfer was not for value, and (C) for all transfers (other than a transfer described in clause (B) immediately above), no public report or filing with the SEC is required to be filed during the lock-up period set forth herein and the undersigned does not otherwise voluntarily effect any public filing or report regarding such transfer.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this lock-up agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this lock-up agreement. All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.
