As Representatives of the several Underwriters

Ladies and Gentlemen:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. **Introductory**. COPT Defense Properties, L.P., a Delaware limited partnership (the "**Operating Partnership**"), proposes to issue and sell to Wells Fargo Securities, LLC, PNC Capital Markets LLC, TD Securities (USA) LLC, and each of the other Underwriters named in <u>Schedule I</u> hereto (collectively, the "**Underwriters**"), for whom Wells Fargo Securities, LLC, PNC Capital Markets LLC and TD Securities (USA) LLC are acting as representatives (in such capacity, the "**Representatives**"), with respect to the issue and sale by the Operating Partnership and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in said <u>Schedule I</u> hereto of $400,000,000 aggregate principal amount of the Operating Partnership's 4.500% Senior Notes due 2030 (the "**Notes**"). The Operating Partnership's obligations under the Notes and the Indenture (as defined below) will be guaranteed on a senior unsecured basis (the "**Guarantee**") by COPT Defense Properties, a Maryland real estate investment trust (the "**Company**"). The Notes will be issued pursuant to a base indenture dated as of April 8, 2019 (the "**Base Indenture**") by and among the Operating Partnership, the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the "**Trustee**"), as supplemented by a fifth supplemental indenture to be dated as of October 2, 2025 (the "**Supplemental Indenture**" and, together with the Base Indenture, the "**Indenture**"). All references herein to the Notes include the related Guarantee unless the context otherwise requires. The Company and the Operating Partnership hereby agree with the Underwriters as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. **Representations and Warranties of the Company and the Operating Partnership**. Each of the Company and the Operating Partnership jointly and severally represent, warrant and agree to each Underwriter, as of the date hereof, as of the time of sale of the Notes and as of the Closing Date (as defined below), **provided**, **however that** certain of the representations and warranties made below are made as of the time specified below, that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) An "automatic shelf registration statement" as defined under Rule 405 under the Securities Act of 1933, as amended (the "**Securities Act**"), on Form S-3ASR (File Nos. 333-286440 and 333-286440-01), relating to the Notes being sold by the Company and the Operating Partnership, including a base prospectus, has been filed with the Securities and Exchange Commission (the "**Commission**") under the Securities Act and such registration statement ("**registration statement**") became effective upon filing with the Commission. For purposes of this Agreement, "**Effective Time**" means the date and time as of which the registration statement became effective upon filing with the Commission. "**Effective Date**" with respect to the registration statement means the date of the Effective Time thereof. The registration statement, as amended at its Effective Time, including all material incorporated by reference therein, pursuant to the General Instructions of the Form on which it is filed and including all information (if any) deemed to be a part of the registration statement as of its Effective Time pursuant to Rule 430B ("**Rule 430B**") under the Securities Act, is hereinafter referred to as a "**Registration Statement**." The base prospectus, together with the final prospectus supplement setting forth the final terms of the offering, sale and plan of distribution of the Notes, as filed with the Commission pursuant to and in accordance with Rule 430B and Rule 424(b) ("**Rule 424(b)**") under the Securities Act and as included in the Registration Statement, including all material incorporated by reference in such prospectus, are hereinafter referred to as the "**Prospectus**." The prospectus subject to completion in the form included in the Registration Statement at the time of the initial filing of such Registration Statement with the Commission and as such prospectus is amended or supplemented pursuant to a preliminary prospectus supplement filed with the Commission pursuant to and in accordance with Rule 424(b) and Rule 430B from time to time until the date of the Prospectus is referred to in this Agreement as the "**Preliminary Prospectus**." For purposes of this Agreement, "**free writing prospectus**" has the meaning ascribed to it in Rule 405 under the Securities Act, and "**Issuer Free Writing Prospectus**" shall mean each free writing prospectus prepared by or on behalf of the Operating Partnership or the Company or used or referred to by the Operating Partnership or the Company in connection with the offering of the Notes. "**Time of Sale Information**" shall mean the Preliminary Prospectus together with the information listed in <u>Schedule I</u> hereto and the free writing prospectuses, if any, each identified in <u>Schedule II</u> hereto. All references in this Agreement to the Registration Statement, a Preliminary Prospectus, the Prospectus or the Time of Sale Information, or any amendments or supplements to any of the foregoing, shall be deemed to refer to and include any documents included therein or deemed to be incorporated by reference therein, and shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System ("**EDGAR**"). Each of the Company and the Operating Partnership meets the requirements for the use of Form S-3 under the Securities Act and the Registration Statement meets the requirements of, and complies in all material respects with, Rule 415(a)(1)(x) under the Securities Act.

All references in this Agreement to financial statements and schedules and other information which is "contained," "included" or "stated" in the Registration Statement, any Preliminary Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in or otherwise deemed by the rules and regulations of the Commission under the Securities Act (the "**Rules and Regulations**") to be a part of or included in the Registration Statement, any Preliminary Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the "**Exchange Act**") or the rules and regulations of the Commission under the Exchange Act (the "**Exchange Act Regulations**") which is incorporated by reference in or otherwise deemed by the Rules and Regulations to be a part of or included in the Registration Statement, such Preliminary Prospectus or the Prospectus, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) On the Effective Date of the Registration Statement, at the effective time of any amendment to the Registration Statement, and at the time the most recent Annual Report on Form 10-K was filed, and at each deemed effective date (the "**deemed effective date**") with respect to the Underwriters pursuant to Rule 430(B)(f)(2) under the Securities Act, the Registration Statement (and with respect to each deemed effective date, the part of the Registration Statement relating to the Notes) complied as to form in all material respects to the requirements of the Securities Act and the Rules and Regulations and did not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading. At the time of filing of each of the Preliminary Prospectus and the Prospectus pursuant to Rule 424(b) and at the Closing Date (as hereinafter defined), each of the Preliminary Prospectus and the Prospectus will comply as to form, in all material respects, to the requirements of the Securities Act and the Rules and Regulations, and will not include any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances in which they were made. The Time of Sale Information does not, and will not at the time of sale of the Notes and at the Closing Date, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Registration Statement, the Preliminary Prospectus, the Prospectus or the Time of Sale Information based upon written information furnished to the Company and the Operating Partnership by the Underwriters specifically for use therein, it being understood and agreed that the only such information is that described as such in <u>Section 7(b)</u> hereof. Each Preliminary Prospectus, the Prospectus and Issuer Free Writing Prospectus delivered to the Underwriters for use in connection with this offering was identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use, and the Company and the Operating Partnership have complied with all prospectus delivery and any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Securities Act and the Rules and Regulations. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the public offer and sale of the Notes or until any earlier date that the Company and the Operating Partnership notified or notify the Underwriters, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, the Preliminary Prospectus or the Prospectus, including any document incorporated by reference therein and any preliminary or other prospectus supplement deemed to be a part thereof that has not been superseded or modified. The Company and the Operating Partnership have not made any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Underwriters. The Company and the Operating Partnership have retained in accordance with the Securities Act all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Securities Act. The Company and the Operating Partnership have taken all actions necessary so that any "road show" (as defined in Rule 433) in connection with the offering of the Notes will not be required to be filed pursuant to the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) (A) At the respective times the Registration Statement or any amendments thereto were filed with the Commission, (B) at the time of the most recent amendment to the Registration Statement for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (C) at any time the Operating Partnership, the Company or any person acting on their behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Notes in reliance on the exemption of Rule 163 and (D) at the date hereof, the Company and the Operating Partnership were and are "well-known seasoned issuers" as defined in Rule 405, including not having been and not being an "ineligible issuer" as defined in Rule 405 (without taking into account any determination made by the Commission pursuant to paragraph (2) of the definition of such term in Rule 405). The Registration Statement is an "automatic shelf registration statement," as defined in Rule 405 and the Notes, since their registration on the Registration Statement, have been and remain eligible for registration by the Company and the Operating Partnership on such an "automatic shelf registration statement." The Company and the Operating Partnership have not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to the use of the automatic shelf registration statement form. Any written communication that was an offer relating to the Notes made by the Operating Partnership, the Company or any person acting on their behalf (within the meaning, for this sentence only, of Rule 163(c)) prior to the filing of the Registration Statement has been filed with the Commission in accordance with Rule 163 and otherwise complied with the requirements of Rule 163, including without limitation the legending requirement, to qualify such offer for the exemption from Section 5(c) of the Securities Act provided by Rule 163.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The Prospectus shall incorporate by reference the most recent Annual Report of the Company and the Operating Partnership on Form 10-K filed with the Commission, and each Quarterly Report of the Company and the Operating Partnership on Form 10-Q and Current Report of the Company and the Operating Partnership on Form 8-K filed with the Commission since the filing of the Annual Report. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Prospectus and the Time of Sale Information, at the time they were or hereafter are filed with the Commission, complied and shall comply in all material respects with the requirements of the Exchange Act and the Exchange Act Regulations and, when read together with the other information in the Prospectus and the Time of Sale Information, at (a) the time the Registration Statement became effective, (b) the earlier of the time the Prospectus was first used and the date and time (the "**Applicable Time**") of the first contract of sale of Notes in this offering, and (c) the Closing Date (as hereinafter defined), did not and shall not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the Securities Act, and the Company and the Operating Partnership are not the subject of a pending proceeding under Section 8A of the Securities Act in connection with the offering of the Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) No stop order suspending the effectiveness of the Registration Statement or any part thereof has been issued and, to the knowledge of the Company and the Operating Partnership, no proceeding for that purpose has been instituted or threatened by the Commission or by the state securities authority of any jurisdiction. No order preventing or suspending the use of the Preliminary Prospectus or the Prospectus has been issued and, to the knowledge of the Company and the Operating Partnership, no proceeding for that purpose has been instituted or threatened by the Commission or by the state securities authority of any jurisdiction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Company has been duly organized and is an existing real estate investment trust ("**REIT**") in good standing under the laws of the State of Maryland, with power and authority as a REIT to own its properties and conduct its business as described in the Prospectus and the Time of Sale Information; and the Operating Partnership has been duly organized and is an existing limited partnership in good standing under the laws of the State of Delaware, with power and authority to own its properties and conduct its business as described in Prospectus and the Time of Sale Information, and each of the Company and the Operating Partnership is duly qualified to do business as a foreign entity in good standing in all other jurisdictions in which its ownership or lease of property or the conduct of its business requires such qualification, except where the failure to be so qualified would not reasonably be expected to have a material adverse effect on (i) the condition (financial or other), business, properties, prospects, net worth or results of operations of the Company, the Operating Partnership and the Subsidiaries (as hereinafter defined) taken as a whole, (ii) the issuance or validity of the Notes or (iii) the consummation of any of the transactions contemplated by this Agreement to be performed by the Company and/or the Subsidiaries (individually or collectively, a "**Material Adverse Effect**").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Each subsidiary of the Company is listed on <u>Schedule III</u> hereto (each, a "**Subsidiary**" and collectively, the "**Subsidiaries**") and has been duly organized and is validly existing as a corporation, limited partnership or other legal entity, as the case may be, in good standing under the laws of its respective jurisdiction of incorporation or formation, with power and authority (corporate and other) to own its properties and conduct its business as described in the Prospectus and the Time of Sale Information; and each Subsidiary is duly qualified to do business as a foreign corporation, limited partnership or other legal entity, as the case may be, in good standing in all other jurisdictions in which such Subsidiary's ownership or lease of property or the conduct of such Subsidiary's business requires such qualification, except where the failure to be so qualified would not reasonably be expected to have a Material Adverse Effect. The issued and outstanding common units of limited partnership interest in the Operating Partnership ("**Units**") and other equity interests, as the case may be, of each of the other Subsidiaries have been duly authorized and validly issued, are, with respect to corporate Subsidiaries, fully paid and nonassessable and, except as otherwise set forth in the Prospectus and the Time of Sale Information or reflected in the financial statements contained in, or incorporated by reference in, the Prospectus and the Time of Sale Information, are owned beneficially by the Company, directly or indirectly through one or more Subsidiaries, free and clear of any security interests, liens, encumbrances, equities or claims, except for security interests, liens, encumbrances, equities or claims pursuant to the terms of a bona fide financing transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) Complete and correct copies of the declaration of trust and of the bylaws of the Company, the certificate of limited partnership and agreement of limited partnership of the Operating Partnership and the charter documents, partnership agreements and other organizational documents of the other Subsidiaries, as applicable, and all amendments thereto as have been requested by the Underwriters or their counsel have been delivered to the Underwriters or their counsel. The partnership agreement of the Operating Partnership, as amended, has been duly authorized, executed and delivered by the Company, as the general partner and as a limited partner and (assuming it has been duly authorized, executed and delivered by each of the other parties thereto, and is a legal, valid and binding agreement of each such other party) is in full force and effect, subject to (i) the effect of bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors, (ii) the effect of general principles of equity, whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefore may be brought and (iii) the provisions of the Delaware Revised Uniform Limited Partnership Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) The Company and the Operating Partnership have an authorized, issued and outstanding capitalization as set forth in the Prospectus and the Time of Sale Information. All of the issued and outstanding common shares of beneficial interest, par value $0.01 per share (the "**Common Shares**"), of the Company and Units of the Operating Partnership have been duly authorized and validly issued and are fully paid and non-assessable. The Common Shares conform in all material respects to the description thereof contained in the Registration Statement, the Prospectus and the Time of Sale Information. None of the outstanding Common Shares or Units of the Operating Partnership were issued in violation of any preemptive rights, rights of first refusal or other similar rights to subscribe for or purchase securities of the Company and the Operating Partnership. The descriptions of the Company's stock option, stock bonus and other stock plans or arrangements, and the options or other rights granted thereunder, set forth or incorporated by reference in the Time of Sale Information and the Prospectus accurately and fairly present the information required to be shown with respect to such plans, arrangements, options and rights.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) The Notes will be in the form contemplated by, and are entitled to the benefits of, the Indenture, and have been duly authorized by all necessary action of the Company and the Operating Partnership and at the Closing Date, when issued and authenticated in the manner provided for in the Indenture and delivered and paid for as contemplated by this Agreement, will constitute valid and legally binding obligations of the Operating Partnership, as issuer, and the Company, as guarantor, enforceable against the Operating Partnership, as issuer, and the Company, as guarantor, in accordance with their terms, except as the enforcement thereof may be limited by bankruptcy, insolvency, reorganization, moratorium or other similar laws relating to or affecting creditors' rights generally or by general equitable principles. The Notes and the Guarantee will conform in all material respects to all statements and descriptions related thereto contained in the Prospectus and Time of Sale Information. The Notes will rank equally with all unsecured indebtedness (other than subordinated indebtedness) of the Operating Partnership that is outstanding on the Closing Date or that may be incurred thereafter and senior to all subordinated indebtedness of the Operating Partnership that is outstanding on the Closing Date or that may be incurred thereafter, except that such Notes will be effectively subordinate to the prior claims of each secured mortgage lender to the extent of the property securing such mortgage and any claims of creditors of entities wholly or partly owned, directly or indirectly, by the Operating Partnership to the extent of the assets of those entities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. **Indemnification and Contribution.**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company and the Operating Partnership will jointly and severally indemnify and hold harmless each Underwriter, its partners, directors and officers and affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities, joint or several, to which the Underwriters 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 an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any preliminary prospectus supplement, the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus (as amended or supplemented) or any other prospectus relating to the Notes, or any amendment or supplement thereto (including the information deemed to be a part of the Registration Statement pursuant to Rule 434 under the Securities Act, if applicable), or arise out of or are based upon 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, and will reimburse the Underwriters for any legal or other expenses reasonably incurred by the Underwriters in connection with investigating or defending any such action or claim as such expenses are incurred; **provided**, **however**, **that** neither the Company nor the Operating Partnership shall 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 as amended or supplemented or any other prospectus relating to the Notes or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by the Underwriters for use therein, it being understood and agreed that the only such information furnished by the Underwriters consists of the information described as such in <u>subsection (b)</u> below by the Underwriters expressly for use in the Preliminary Prospectus, the Prospectus or the Time of Sale Information, as amended or supplemented relating to such Notes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Underwriter, severally and not jointly, will indemnify and hold harmless the Company and the Operating Partnership, its trustees and officers and each person, if any who controls the Company or the Operating Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any losses, claims, damages or liabilities to which the Company or the Operating Partnership 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 an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, any preliminary prospectus supplement, the Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus (as amended or supplemented) or any other prospectus relating to the Notes, or any amendment or supplement thereto (including the information deemed to be a part of the Registration Statement pursuant to Rule 433 under the Securities Act, if applicable), or arise out of or are based upon 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 Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus (as amended or supplemented) or any other prospectus relating to the Notes or any such amendment or supplement in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by the Underwriters through the Representatives expressly for use therein; and will reimburse the Company and the Operating Partnership for any legal or other expenses reasonably incurred by the Company or the Operating Partnership in connection with investigating or defending any such action or claim as to which the Company or the Operating Partnership shall be entitled to indemnification under this <u>subsection (b)</u> as such expenses are incurred, it being understood and agreed that the only such information furnished by the Underwriters through the Representatives consists of the following information in the Preliminary Prospectus, the Prospectus or the Time of Sale Information furnished by the Underwriters: the information in the third sentence of the fourth paragraph and the information in the seventh, eighth, and tenth paragraphs under the caption "Underwriting (Conflicts of Interest)."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Promptly after receipt by an indemnified party under <u>subsection (a)</u> or <u>(b)</u> 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 <u>subsection (a)</u> or <u>(b)</u> above, except to the extent such omission so to notify the indemnifying party materially prejudices the indemnifying party. 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 reasonably 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 (unless separate counsel is required due to conflict of interest) 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. No indemnifying party shall, without 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, compromises 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If the indemnification provided for in this <u>Section 7</u> is unavailable to or insufficient to hold harmless an indemnified party under <u>subsection (a)</u> or <u>(b)</u> 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 Company or the Operating Partnership on the one hand and the Underwriters on the other from the offering of the Notes 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 <u>subsection (c)</u> 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 but also the relative fault of the Company or the Operating Partnership on the one hand and the Underwriters 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 or the Operating Partnership on the one hand and the 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 Company or the Operating Partnership bear to the total underwriting discounts and commissions from such offering received by the Underwriters. 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 relates to information supplied by the Company or the Operating Partnership on the one hand or the 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 <u>subsection (d)</u> were determined by *pro rata* allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this <u>subsection (d)</u>. 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 <u>subsection (d)</u> 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 <u>subsection (d)</u>, the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which the Underwriters have 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) The obligations of the Company and the Operating Partnership under this <u>Section 7</u> shall be in addition to any liability which the Company and the Operating Partnership may otherwise have and, with respect to each Underwriter, shall extend, upon the same terms and conditions, to each person, if any, who controls such Underwriter within the meaning of the Securities Act; and the obligations of the Underwriters under this <u>Section 7</u> shall be in addition to any liability which the Underwriters may otherwise have and shall extend, upon the same terms and conditions, to each officer of the Company who signed the Registration Statement, trustee of the Company and to each person, if any, who controls the Company and the Operating Partnership within the meaning of the Securities Act.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. **Defaulting Underwriters**. If any one or more of the Underwriters shall fail or refuse to purchase Notes that it or they have agreed to purchase hereunder, and the aggregate principal amount of Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate principal amount of Notes, each non-defaulting Underwriter shall be obligated, severally, in the proportion in which the principal amount of Notes set forth opposite its name in <u>Schedule I</u> hereto bears to the aggregate principal amount of Notes set forth opposite the names of all non-defaulting Underwriters or in such other proportion as the Representatives may specify, to purchase the Notes that such defaulting Underwriter or Underwriters agreed, but failed or refused to purchase. If any Underwriter or Underwriters shall fail or refuse to purchase Notes and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes and arrangements satisfactory to the Operating Partnership and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case that does not result in termination of this Agreement, either the Operating Partnership or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, the Prospectus and any Free Writing Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. **Survival of Certain Representations and Obligations**. The respective indemnities, agreements, representations, warranties and other statements of the Company and the Operating Partnership or any of their respective officers and of the Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of the Underwriters, the Company, the Operating Partnership or any of their respective representatives, officers or trustees or any controlling person, and will survive delivery of and payment for the Notes. If for any reason the purchase of the Notes by the Underwriters is not consummated, the Company and the Operating Partnership shall remain responsible for the expenses to be paid or reimbursed by it pursuant to <u>Section 5</u> and the respective obligations of the Company, the Operating Partnership and the Underwriters pursuant to <u>Section 7</u> shall remain in effect, and if any Notes have been purchased hereunder the representations and warranties in <u>Section 2</u> and all obligations under <u>Section 5</u> shall also remain in effect. If the purchase of the Notes by the Underwriters is not consummated for any reason, other than solely because of the occurrence of any event specified in <u>clause (iii)</u>, <u>(iv)</u> or <u>(v)</u> of <u>Section 6(c)</u>, the Company and the Operating Partnership will reimburse the Underwriters for all out-of-pocket expenses reasonably incurred by them in connection with the offering of the Notes, including but not limited to fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;10. **Notices**.

This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and trustees and controlling persons referred to in <u>Section 7</u>, and no other person will have any right or obligation hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12. **Absence of Fiduciary Relationship**. Each of the Company and the Operating Partnership acknowledges and agrees that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Underwriters have been retained solely to act as underwriters in connection with the sale of the Notes and that no fiduciary, advisory or agency relationship between the Company, the Operating Partnership and the Underwriters has been created in respect of any of the transactions contemplated by this Agreement, irrespective of whether the Underwriters have advised or is advising the Company or the Operating Partnership on other matters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) the price of the Notes set forth in this Agreement was established by the Company and the Operating Partnership following discussions and arms-length negotiations with the Underwriters, and each of the Company and the Operating Partnership is capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) it has been advised that the Underwriters and their respective affiliates are engaged in a broad range of transactions that may involve interests that differ from those of the Company or the Operating Partnership and that the Underwriters have no obligation to disclose such interests and transactions to the Company or the Operating Partnership by virtue of any fiduciary, advisory or agency relationship; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) it waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Company or the Operating Partnership in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Company or the Operating Partnership, including shareholders, partners, employees or creditors of the Company or the Operating Partnership.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;13. **Qualified Financial Contract**. In the event that any party to this Agreement is not a company (i) that is incorporated or organized under the laws of the United States or any state thereof or (ii) with its principal place of business in the United States or any state thereof, then the following provisions shall be applicable to this Agreement and any transaction hereunder:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In the event that an Underwriter that is a Covered Entity or a BHC Act Affiliate of an Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, any Default Rights under this Agreement that may be exercised against such party that is a Covered Entity are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime.
