To the Representatives of the
several Underwriters named in the
respective Pricing Agreements
hereinafter described

Ladies and Gentlemen:

From time to time Brandywine Operating Partnership, L.P., a Delaware limited partnership (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, to issue and sell to the firms named in Schedule I to the applicable Pricing Agreement (such firms constituting the “Underwriters” with respect to such Pricing Agreement and the securities specified therein) certain of its debt securities (the “Securities”) specified in Schedule II to such Pricing Agreement (with respect to such Pricing Agreement, the “Designated Securities”). The Securities shall be unconditionally guaranteed (the “Guarantees”) by Brandywine Realty Trust, a Maryland real estate investment trust and the sole general partner and a limited partner of the Operating Partnership (the “Parent Guarantor”), and certain of the Operating Partnership’s subsidiaries (the “Subsidiary Guarantors” and, together with the Parent Guarantor, the “Guarantors”).

The terms and conditions of any particular issuance of Designated Securities shall be as specified in the Pricing Agreement relating thereto and in or pursuant to the Indenture (the “Indenture”) identified in such Pricing Agreement.

1. Particular sales of Designated Securities may be made from time to time to the Underwriters of such Designated Securities, for whom the firms designated as representatives of the Underwriters of such Designated Securities in the Pricing Agreement relating thereto shall act as representatives (the “Representatives”). The term “Representatives” also refers to a single firm acting as sole representative of the Underwriters and to an Underwriter or Underwriters who act without any firm being designated as its or their representatives. This Underwriting Agreement (the “Agreement”) shall not be construed as an obligation of the Operating Partnership to offer, issue or sell any of the Securities or as an obligation of any of the Underwriters to purchase the Securities. The obligation of the Operating Partnership to issue and sell any of the Securities and the obligation of any of the Underwriters to purchase any of the Securities shall be evidenced by the Pricing Agreement with respect to the Designated Securities specified therein. Each Pricing Agreement shall specify the aggregate principal amount of such Designated Securities, the initial public offering price of such Designated Securities, the purchase price to the Underwriters of such Designated Securities, the names of the Underwriters of such Designated Securities, the names of the Representatives of such Underwriters and the principal amount of such Designated Securities to be purchased by each Underwriter and shall set forth the date, time and manner of delivery of such Designated Securities and payment therefor. The Pricing Agreement shall also specify (to the extent not set forth in the Indenture and registration statement and prospectus with respect thereto) the terms and conditions of such Designated Securities. A 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 shall be several and not joint.

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

(h) Neither the Operating Partnership nor any of the Guarantors shall be or become, at any time prior to the expiration of three years after the Time of Delivery, an “investment company” or an entity “controlled” by an “investment company”, as such terms are defined in the Investment Company Act.

(i) The Parent Guarantor shall use its best efforts to continue to be organized and operated in conformity with the requirements for qualification as a REIT under the Code for each of its taxable years for so long as the Board of Trustees of the Parent Guarantor deems it in the best interests of the Parent Guarantor’s shareholders to remain so qualified and not to be materially and adversely against the interests of the holders of the Designated Securities to fail to be so qualified.

6.

	(xvi) The statements made under the caption under “Material Federal Income Tax Consequences” in 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;

made by the Operating Partnership and the Guarantors prior to the Time of Delivery (other than the financial statements and related notes and schedules therein, as to which such counsel need 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; and such counsel 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 Prospectus or required to be described in the Registration Statement or the Prospectus that are not filed or incorporated by reference or described as required.

(d) (i) On the date of the applicable Pricing Agreement for such Designated Securities and at the Time of Delivery for such Designated Securities, Pricewaterhouse Coppers LLP, the independent certified public accountants of the Operating Partnership and the Parent Guarantor, who have audited the financial statements of the Operating Partnership and its consolidated subsidiaries and of the Parent Guarantor and its consolidated subsidiaries, included or incorporated by reference in the Registration Statement, shall have furnished to the Representatives letters, dated the respective dates of delivery, in form and substance satisfactory to the Representatives, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement and the Prospectus; and (ii) on the date of the applicable Pricing Agreement for such Designated Securities and at the Time of Delivery for such Designated Securities, Ernst & Young, the independent certified public accountants of The Rubenstein Company, L.P., who have audited the financial statements of The Rubenstein Company, L.P. and its consolidated subsidiaries, included or incorporated by reference in the Registration Statement, shall have furnished to the Representatives letters, dated the respective dates of delivery, in form and substance satisfactory to the Representatives, containing statements and information of the type customarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained or incorporated by reference in the Registration Statement and the Prospectus;

(e) (i) The Parent Guarantor and its subsidiaries (including the Operating Partnership), taken as a whole, have not sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth in the Prospectus and (ii) since the respective dates as of which information is given in the Registration Statement and the Prospectus, there has not been any change in the beneficial interests of the Parent Guarantor (other than issuances of beneficial interests (A) pursuant to equity-based awards granted in the ordinary course of business, (B) upon exercise of options and upon conversion or redemption of convertible or redeemable securities, in each case which were outstanding as of the date of the latest audited financial statements included or incorporated by reference in the Prospectus, and (C) upon the exchange of Operating Partnership interests for beneficial interests in the Parent Guarantor) or in the partnership interests in the Operating Partnership or the capital stock, partnership, membership or beneficial interests of any of its consolidated subsidiaries, or any change in the long-term debt of the Parent Guarantor and its consolidated subsidiaries (including the Operating Partnership), taken as a whole, or any material adverse change, or any development involving a prospective material adverse change, in or affecting the business, properties, management, results of operations, financial condition or prospects of the Parent Guarantor and its consolidated subsidiaries (including the Operating Partnership), taken as a whole, except as set forth in the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is in the judgment of the Representatives so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Designated Securities and the Guarantees on the terms and in the manner contemplated in the Prospectus;

(f) On or after the date of the Pricing Agreement relating to the Designated Securities, (i) no downgrading shall have occurred in the rating accorded the Operating Partnership’s debt securities or the Parent Guarantor’s debt securities or, if applicable, preferred shares of beneficial interest by any “nationally recognized statistical rating organization”, as the term is defined by the Commission for purposes of Rule 436(g)(2) under the Securities Act and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any of the Operating Partnership’s debt securities or the Parent Guarantor’s debt securities or preferred shares;

(h) The Operating Partnership and the Guarantors shall have furnished or caused to be furnished to the Representatives at the Time of Delivery for the Designated Securities a certificate or certificates of officers of the Operating Partnership and the Guarantors in such form and executed by such officers of the Operating Partnership and the Guarantors as shall be satisfactory to the Representatives, as to the accuracy of the representations and warranties of the Operating Partnership and the Guarantors herein at and as of such Time of Delivery, as to the performance by the Operating Partnership and the Guarantors of all of its obligations hereunder to be performed at or prior to such Time of Delivery, as to the matters set forth in Sections 7(a), (g) and (h) and as to such other matters (including, without limitation, with respect to compliance with debt agreements and instruments) as the Representatives may reasonably request.

8. (a) The Operating Partnership, the Parent Guarantor and the Subsidiary Guarantors, jointly and severally, shall indemnify and hold harmless each Underwriter, its directors, officers and employees and each person, if any, who controls any Underwriter within the meaning of the Securities Act, from and against any losses, claims, damages or liabilities, joint or several, or any action in respect thereof to which such Underwriter, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities or actions arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Securities, or any amendment or supplement thereto, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Securities, or any amendments or supplements thereto a material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Underwriter and each such director, officer, employee and controlling person promptly upon demand for any legal or other expenses reasonably incurred by such Underwriter and each such director, officer, employee and controlling person in connection with investigating or defending any such loss, damage, liability, action or claim as such expenses are incurred; provided, however, that the Operating Partnership, the Parent Guarantor and the Subsidiary Guarantors shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Securities, or any such amendment or supplement, in reliance upon and in conformity with information furnished in writing to the Operating Partnership by any Underwriter of Designated Securities through the Representatives expressly for use in the Prospectus relating to such Designated Securities.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Operating Partnership, the Parent Guarantor and the Subsidiary Guarantors against any losses, claims, damages or liabilities to which the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor 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, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Securities, or any amendment or supplement thereto, 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, any preliminary prospectus supplement, the Registration Statement, the Prospectus and any other prospectus relating to the Designated Securities, or any such amendment or supplement, in reliance upon and in conformity with written information furnished to the Operating Partnership by such Underwriter through the Representatives expressly for use therein, and shall reimburse the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor for any legal or other expenses reasonably incurred by the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor 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 8(a) or (b) above of notice of the commencement of any action, such indemnified party shall, 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 shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection. In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall 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 shall not be liable to such indemnified party under such subsection 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 shall 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 shall 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 shall 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 shall 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 shall 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 shall 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 shall be designated in writing by you, if the indemnified parties under this Section 8 consist of any Underwriter of the Designated Securities or any of its respective directors, officers, employees or controlling persons, or by the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor, if the indemnified parties under this Section 8 consist of the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor or any of their directors, officers, administrative trustees or controlling persons. The indemnifying party shall 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 shall not be unreasonably withheld. No indemnifying party shall, 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 8, references to “counsel” shall include a firm of attorneys.

(d) If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall 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 Operating Partnership, the Parent Guarantor and the Subsidiary Guarantors on the one hand and the Underwriters of the Designated Securities on the other from the offering of the Designated Securities 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 8(c) above, then each indemnifying party shall 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 Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor on the one hand and the Underwriters of the Designated Securities 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 Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor on the one hand and such Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor bear to the total commissions or discounts received by such Underwriters in respect thereof. The relative fault shall 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 Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor 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 Operating Partnership, the Parent Guarantor, the Subsidiary Guarantors and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(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 8(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 8(d) shall 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 8(d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total public offering price at which the applicable Designated Securities 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 Securities in this Section 8(d) to contribute are several in proportion to their respective underwriting obligations with respect to such Designated Securities and not joint.

(e) The obligations of the Operating Partnership, the Parent Guarantor and the Subsidiary Guarantors under this Section 8 shall be in addition to any liability which the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of any Underwriter and to each person, if any, who controls any Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this Section 8 shall be in addition to any liability which the respective Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor and to each person, if any, who controls the Operating Partnership, the Parent Guarantor or any Subsidiary Guarantor within the meaning of the Securities Act.

9. (a) If any Underwriter shall default in its obligation to purchase the Designated Securities which it has agreed to purchase under the Pricing Agreement relating to such Designated Securities, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Designated Securities on the terms contained herein. If within 36 hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Designated Securities, then the Operating Partnership shall be entitled to a further period of 36 hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Designated Securities on such terms. In the event that, within the respective prescribed period, the Representatives notify the Operating Partnership that they have so arranged for the purchase of such Designated Securities, or the Operating Partnership notifies the Representatives that it has so arranged for the purchase of such Designated Securities, the Representatives or the Operating Partnership shall have the right to postpone the Time of Delivery for such Designated Securities 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 Operating Partnership agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Representatives may thereby be made necessary. The term “Underwriter” as used in this Agreement shall 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 Securities.

(b) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate principal amount of such Designated Securities which remains unpurchased does not exceed one-eleventh of the aggregate principal amount of the Designated Securities, then the Operating Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Designated Securities which such Underwriter agreed to purchase under the Pricing Agreement relating to such Designated Securities and, in addition, to require each non-defaulting Underwriter to purchase its pro-rata share (based on the principal amount of Designated Securities which such Underwriter agreed to purchase under such Pricing Agreement) of the Designated Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c) If, after giving effect to any arrangements for the purchase of the Designated Securities of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate principal amount of Designated Securities which remains unpurchased exceeds one-eleventh of the aggregate principal amount of the Designated Securities as referred to in subsection (b) above, or if the Operating Partnership shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Designated Securities of a defaulting Underwriter or Underwriters, then the Pricing Agreement relating to such Designated Securities shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Operating Partnership, except for the expenses to be borne by the Operating Partnership and the Underwriters as provided in Section 6 hereof and the indemnity and contribution agreements in Section 8 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

10. The respective indemnities, agreements, representations, warranties and other statements of the Operating Partnership, the Guarantors and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall 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 officer or director or controlling person of any Underwriter, or the Operating Partnership or any Guarantor, or any officer or director or controlling person of the Operating Partnership or any Guarantor, and shall survive delivery of and payment for the Securities.

11. If any Pricing Agreement shall be terminated pursuant to Section 9 hereof or if the condition in Section 7(i) is not satisfied, the Operating Partnership and the Guarantors shall not then be under any liability to any Underwriter with respect to the Designated Securities covered by such Pricing Agreement except as provided in Sections 6 and 8 hereof, but, if for any other reason, Designated Securities are not delivered by or on behalf of the Operating Partnership as provided herein, the Operating Partnership or the Guarantors shall reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of such Designated Securities, but the Operating Partnership and the Guarantors shall then be under no further liability to any Underwriter with respect to such Designated Securities except as provided in Sections 6 and 8 hereof.

12. In all dealings hereunder, the Representatives of the Underwriters of Designated Securities shall act on behalf of each of such Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by such Representatives jointly or by such of the Representatives, if any, as may be designated for such purpose in the Pricing Agreement.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to the address of the Representatives as set forth in the Pricing Agreement; and if to the Operating Partnership or the Guarantors shall be delivered or sent by mail, telex or facsimile transmission to the address of the Operating Partnership and the Guarantors set forth in the Registration Statement, Attention: General Counsel; provided, however, that any notice to an Underwriter pursuant to Section 8(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 shall be supplied to the Operating Partnership by the Representatives upon request. Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

13. This Agreement and each Pricing Agreement shall be binding upon, and inure solely to the benefit of, the Underwriters, the Operating Partnership, the Guarantors and, to the extent provided in Sections 8 and 10 hereof, the directors, officers and employees of the Operating Partnership, the Guarantors or any Underwriter and each person who controls the Operating Partnership, the Guarantors or any Underwriter, and their respective heirs, executors, administrators, successors and assigns, and no other person shall acquire or have any right under or by virtue of this Agreement or any such Pricing Agreement. No purchaser of any of the Securities from any Underwriter shall be deemed a successor or assign by reason merely of such purchase.

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

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

16. 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 shall together constitute one and the same instrument.
