Except as disclosed in or contemplated by the Registration Statement, the General Disclosure Package and the Prospectus (including with respect to restrictions on transfer of property or assets pursuant to the terms of mortgage debt on any properties held directly or indirectly by the Operating Partnership or pursuant to the express terms of any joint venture arrangement of the Operating Partnership or any of its subsidiaries), no subsidiary of the Operating Partnership is currently prohibited, directly or indirectly, from paying any distributions to the Operating Partnership to the extent permitted by applicable law, from making any other distribution on the equity held by the Operating Partnership, or from repaying to the Operating Partnership any loans or advances made by the Operating Partnership to any such subsidiary.

(23)    REIT Qualification. With respect to all tax periods regarding which the Internal Revenue Service is or will be entitled to assert any claim, the Company has met the requirements for qualification as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the “Code”), and the Company’s present and contemplated operations, assets and income meet and will enable it to continue to meet such requirements.

(24)    Operating Partnership Tax Status. Since it became a subsidiary of the Company, the Operating Partnership has been and will continue to be classified as a disregarded entity or a partnership that is not a “publicly traded partnership” taxable as a corporation for U.S. federal income tax purposes.

(26)    Tax Compliance.

12

taxes as (i) are not yet due, (ii) are being contested in good faith by appropriate proceedings diligently conducted and for which adequate reserves are being maintained in accordance with GAAP, or (iii) could not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect.

(27)    Possession of Licenses and Permits. The Federal Entities hold all material licenses, certificates and permits from governmental authorities which are necessary to the conduct of their respective businesses; and none of the Federal Entities have infringed any patents, patent rights, trade names, trademarks or copyrights, which infringement is material to the business of the Federal Entities, considered as one enterprise.

(29)    Environmental Laws. Although the Company and the Operating Partnership are aware of the presence of hazardous substances, hazardous materials, toxic substances or waste materials (“Hazardous Materials”) on certain of the properties of the Federal Entities, nothing has come to the attention of the Company or the Operating Partnership which, at this time, would lead the Company or the Operating Partnership to believe that the presence of such Hazardous Materials, when considered in the aggregate, would materially adversely affect the financial condition of the Operating Partnership. In connection with the construction on or operation and use of the properties owned or leased by the Federal Entities, the Company and the Operating Partnership represent that, as of the date hereof, it has no knowledge of any material failure by the Federal Entities to comply with all applicable local, state and federal environmental laws, regulations, ordinances and administrative and judicial orders relating to the generation, recycling, reuse, sale, storage, handling, transport and disposal of any Hazardous Materials.

13

(33)    Foreign Corrupt Practices Act. None of the Federal Entities nor, to the knowledge of the Company or the Operating Partnership, any director, trustee, officer, agent, employee or other person associated with or acting on behalf of any Federal Entity, has violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, as amended, or the Bribery Act 2010 of the United Kingdom, and the Federal Entities have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(34)    Money Laundering Laws. The operations of the Federal Entities are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the money laundering statutes and the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving any Federal Entity with respect to the Money Laundering Laws is pending or, to the knowledge of the Company or the Operating Partnership, threatened.

(35)    OFAC. None of the Federal Entities nor, to the knowledge of the Company or the Operating Partnership, any director, trustee, officer, agent, employee or affiliate of any Federal Entity is (i) currently subject to any sanctions administered or enforced by the U.S. Government (including, without limitation, the Office of Foreign Assets Control of the U.S. Department of the Treasury (“OFAC”) or other relevant sanctions authority (collectively, “Sanctions”)); or (ii) located, organized or resident in a country or territory that is, or whose government is, the subject of Sanctions, including, without limitation, Cuba, Iran, North Korea, Russia, Syria, the Crimea region of Ukraine and the non-government controlled areas of the Zaporizhzhia and Kherson Regions of Ukraine, the so-called Donetsk People’s Republic, and the so-called Luhansk People’s Republic, that broadly prohibit dealings with that country or territory (each, a “Sanctioned Country”); and the Federal Entities will not directly or indirectly use the proceeds of the offering of the Notes hereunder, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any Sanctions.

(36)    Cybersecurity. (i) To the knowledge of the Company and the Operating Partnership, there has been no security breach or incident, unauthorized access or disclosure, or other compromise relating to any Federal Entity’s information technology and computer systems, networks, hardware, software, data and databases (including the data and information of their respective customers, employees, suppliers, vendors and any third party data maintained, processed or stored by any Federal Entity, and any such data processed or stored by third parties on behalf of any Federal Entity), equipment or technology (collectively, “IT Systems and Data”); (ii) no Federal Entity has been notified of, and neither the Company nor the Operating Partnership has knowledge of any event or condition that could result in, any security breach or incident, unauthorized access or disclosure or other compromise to any Federal Entity’s IT Systems and Data; and (iii) the Federal Entities have implemented appropriate controls, policies, procedures, and

technological safeguards to maintain and protect the integrity, continuous operation, redundancy and security of their IT Systems and Data reasonably consistent with industry standards and practices, or as required by applicable regulatory standards, except, in each case with respect to clauses (i) and (ii) above, as would not, individually or in the aggregate, have a Material Adverse Effect, and except, in the case of clause (iii) above, where the failure to do so would not, individually or in the aggregate, have a Material Adverse Effect. The Federal Entities are presently in material compliance with all applicable laws or statutes and all judgments, orders, rules and regulations of any court or arbitrator or governmental or regulatory authority, internal policies and contractual obligations relating to the privacy and security of IT Systems and Data and to the protection of such IT Systems and Data from unauthorized use, access, misappropriation or modification, except where the failure to be so in material compliance would not, individually or in the aggregate, have a Material Adverse Effect.

(b)    Officers’ Certificates. Any certificate signed by any officer of the Company or the Operating Partnership or any authorized representative of the Company or the Operating Partnership delivered to the Representatives or to counsel for the Underwriters in connection with the offering of the Notes shall be deemed a representation and warranty by the Company or the Operating Partnership, as the case may be, to each Underwriter as to the matters covered thereby on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

SECTION 3    Covenants of the Operating Partnership.

The Operating Partnership covenants with each Underwriter as follows:

(a)    Compliance with Securities Regulations and Commission Requests; Payment of Filing Fees. The Operating Partnership, subject to Section 3(e), will comply with the requirements of Rule 430B and during the period a prospectus relating to the Notes is (or, but for the exception afforded by Rule 172 of the 1933 Act Regulations would be) required by the 1933 Act to be delivered in connection with any sales of the Notes, will notify the Representatives immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement or new registration statement relating to the Notes shall become effective, or any supplement to the Prospectus or any amended Prospectus shall have been filed, (ii) of the receipt of any comments from the Commission, (iii) of any request by the Commission for any amendment to the Registration Statement or the filing of a new registration statement or any amendment or supplement to the Prospectus or any document incorporated by reference therein or otherwise deemed to be a part thereof or for additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or such new registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the qualification of the Notes for offering or sale in any jurisdiction, or of the initiation or threatening of any proceedings for any of such purposes or of any examination pursuant to Section 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Operating Partnership becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Notes. The Operating Partnership will effect the filings required under Rule 424(b), in the manner and within the time period required by Rule 424(b) (without reliance on Rule 424(b)(8)), and will take such steps as it deems necessary to ascertain promptly whether the form of prospectus transmitted for filing under Rule 424(b) was received for filing by the Commission and, in the event that it was not, it will promptly file such prospectus. The Operating Partnership will make every reasonable effort to prevent the issuance of any stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment. The Operating Partnership shall pay the required Commission filing fees relating to the Notes within the time required by Rule 456(b)(1) (i) of the 1933 Act Regulations without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations (including, if applicable, by updating the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b)).

16

(b)    Delivery of Registration Statements. The Operating Partnership has furnished or will deliver to the Representatives and counsel for the Underwriters, without charge, signed copies of the Original Registration Statement and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated by reference therein or otherwise deemed to be a part thereof) and signed copies of all consents and certificates of experts, and will also deliver to the Representatives, without charge, a conformed copy of the Original Registration Statement and of each amendment thereto (without exhibits) for each of the Underwriters. The copies of the Original Registration Statement and each amendment thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

(c)    Delivery of Prospectus(es). The Operating Partnership has delivered to each Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Operating Partnership has delivered to each Underwriter, without charge, as many copies of each Issuer Free Writing Prospectus, if any, as such Underwriter reasonably requested, and the Operating Partnership hereby consents to the use of such copies of each preliminary prospectus and each Issuer Free Writing Prospectus, if any, for purposes permitted by the 1933 Act. The Operating Partnership will furnish to each Underwriter, without charge, during the period when a prospectus is required to be delivered under the 1933 Act in connection with sales of the Notes, such number of copies of the prospectus, as amended or supplemented, as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriters will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T. The Operating Partnership, during the period when the Prospectus is required to be delivered under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the rules and regulations of the Commission thereunder.

(d)    Notice and Effect of Material Events. The Operating Partnership will comply with the 1933 Act and the rules and regulations of the Commission thereunder, the 1934 Act and the rules and regulations of the Commission thereunder and the 1939 Act and the rules and regulations of the Commission thereunder so as to permit the completion of the distribution of the Notes as contemplated in this Agreement and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriters or for the Operating Partnership, to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary, in the opinion of such counsel, at any such time to amend the Registration Statement or to file a new registration statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the rules and regulations thereunder, the Operating Partnership will promptly prepare and file with the

17

Commission, subject to Section 5(a) hereof, such amendment, supplement or new registration statement as may be necessary to correct such statement or omission or to comply with such requirements, the Operating Partnership will use its reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable (if it is not an automatic shelf registration statement with respect to the Notes) and the Operating Partnership will furnish to the Underwriters such number of copies of such amendment, supplement or new registration statement as the Representatives may reasonably request. If, during the time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Notes and following issuance of an Issuer Free Writing Prospectus, there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information contained in the Registration Statement (or any other registration statement relating to the Notes) or the Statutory Prospectus or any preliminary prospectus or included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances prevailing at that subsequent time, not misleading, the Operating Partnership will promptly notify the Representatives and will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(e)    Filing of Amendments and 1934 Act Documents; Preparation of the Final Term Sheet. From the Applicable Time to the Closing Time, the Operating Partnership will give the Representatives notice of its intention to file or prepare any amendment to the Registration Statement or new registration statement relating to the Notes or any amendment, supplement or revision to either any preliminary prospectus (including any prospectus included in the Original Registration Statement or amendment thereto at the time it became effective) or to the Prospectus, whether pursuant to the 1933 Act, the 1934 Act or otherwise, and the Operating Partnership will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object. The Operating Partnership has given the Representatives notice of any filings made pursuant to the 1934 Act or the Commission’s regulations thereunder within forty-eight hours prior to the Applicable Time. The Operating Partnership will prepare a final term sheet (the “Final Term Sheet”) reflecting the final terms of the Notes, substantially in the form set forth on Schedule 4 hereto, and shall file such Final Term Sheet as an “issuer free writing prospectus” pursuant to Rule 433 prior to the close of business two business days after the date hereof; provided that the Operating Partnership shall furnish the Representatives with copies of such Final Term Sheet a reasonable amount of time prior to such proposed filing and will not use or file any such document to which the Representatives or counsel to the Underwriters shall reasonably object.

(f)    Blue-Sky Qualifications. The Operating Partnership shall use its best efforts, in cooperation with the Underwriters, to qualify the Notes for offering and sale under the applicable securities laws of such states and other jurisdictions (domestic or foreign) as the Underwriters may designate and to maintain such qualifications in effect for a period of not less than one year from the date of this Agreement; provided, however, that the Operating Partnership shall not be obligated to file any general consent to service of process or to qualify or register as a foreign partnership or as a dealer in securities in any jurisdiction in which it is not so qualified or registered, or provide any undertaking or make any change in its charter or by-laws that the

18

Board of Trustees of the Company reasonably determines to be contrary to the best interests of the Operating Partnership and its unitholders or to subject itself to taxation in respect of doing business in any jurisdiction in which it is not otherwise so subject. In each jurisdiction in which the Notes have been so qualified or registered, the Operating Partnership shall file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for a period of not less than one year from the date of this Agreement. The Operating Partnership will also supply the Underwriters with such information as is necessary for the determination of the legality of the Notes for investment under the laws of such jurisdictions as the Underwriters may request.

(g)    Stop Order by State Securities Commission. The Operating Partnership shall advise the Underwriters promptly and, if requested by any Underwriter, to confirm such advice in writing, of the issuance by any state securities commission of any stop order suspending the qualification or exemption from qualification of any of the Notes for offering or sale in any jurisdiction, or the initiation of any proceeding for such purpose by any state securities commission or other regulatory authority. The Operating Partnership shall use its reasonable best efforts to prevent the issuance of any stop order or order suspending the qualification or exemption of any of the Notes under any state securities or Blue Sky laws, and if at any time any state securities commission or other regulatory authority shall issue an order suspending the qualification or exemption of any of the Notes under any state securities or Blue Sky laws, the Operating Partnership shall use its reasonable best efforts to obtain the withdrawal or lifting of such order at the earliest possible time.

(h)    Earnings Statement. The Operating Partnership shall timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its securityholders as soon as practicable an earnings statement (in form complying with Rule 158 of the 1933 Act Regulations) for the purposes of, and to provide to the Underwriters the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(i)    Reporting Requirements. The Operating Partnership, during the period when a prospectus is required to be delivered (or but for Rule 172 of the 1933 Act Regulations would be required to be delivered) under the 1933 Act, will file all documents required to be filed with the Commission pursuant to the 1934 Act within the time periods required by the 1934 Act and the 1934 Act Regulations.

(j)    Issuer Free Writing Prospectuses. The Operating Partnership represents and agrees that, unless it obtains the prior written consent of the Underwriters, and each Underwriter represents and agrees that, unless it obtains the prior written consent of the Operating Partnership and the other Underwriters, it has not made and will not make any offer relating to the Notes that would constitute an “issuer free writing prospectus,” as defined in Rule 433, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, in each case required to be filed with the Commission; provided, however, that prior to the preparation of the Final Term Sheet in accordance with Section 3(e) hereof, the Underwriters are authorized to use the information with respect to the final terms of the Notes in communications conveying information relating to the offering to investors. Any such free writing prospectus consented to by the Operating Partnership and the Underwriters is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Operating Partnership represents that it has treated or agrees that it

19

will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rule 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

(k)    REIT Qualification. For any taxable years in which the Closing Time occurs, the Company will use its best efforts to continue to meet the requirements to qualify as a “real estate investment trust” under the Code, and the Operating Partnership will use its best efforts to maintain its classification for U.S. federal income tax purposes as a disregarded entity or partnership that is not a “publicly traded partnership” taxable as a corporation, in each case until any such time that the board of trustees of the Company determines that it is no longer in the best interests of the Company to so qualify or for the Operating Partnership to maintain such classification.

(l)    Use of Proceeds. The Operating Partnership shall use the net proceeds received by it from the sale of the Notes in the manner specified in the General Disclosure Package and the Prospectus under “Use of Proceeds.”

(m)    Limitations on Sales of Substantially Similar Notes During the period beginning on and including the date of this Agreement and continuing through the Closing Time, the Operating Partnership will not offer, sell, contract to sell, pledge or otherwise issue any debt securities of the Operating Partnership which mature more than one year after such Closing Time and which are substantially similar to such Notes, without the prior written consent of the Representatives.

SECTION 4    Payment of Expenses.

(a)    Expenses. The Operating Partnership covenants and agrees with the several Underwriters that the Operating Partnership will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Operating Partnership’s counsel and accountants in connection with the registration of the Notes under the 1933 Act and all other expenses in connection with the preparation, printing and filing of the Registration Statement, any preliminary prospectus, Permitted Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement Among Underwriters, this Agreement, any Indenture, any Blue Sky and legal investment surveys and any other documents in connection with the offering, purchase, sale and delivery of the Notes; (iii) all expenses in connection with the qualification of the Notes for offering and sale under state securities laws as provided in Section 3(g) hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky and legal investment surveys; (iv) any fees charged by securities rating services for rating the Notes; (v) any filing fees incident to any required review by FINRA of the terms of the sale of the Notes; (vi) the fees and expenses of any Trustee and any agent of any Trustee and the fees and disbursements of counsel for any Trustee in connection with any Indenture and the Notes; (vii) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section 4; (viii) the costs and expenses (including without limitation any damages or other amounts payable in connection with legal or

(b)    Termination of Agreement.

SECTION 6    Indemnification.

(a)    Indemnification of Underwriters. The Operating Partnership, agrees to indemnify and hold harmless each Underwriter, its affiliates, its directors, its officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the 1933 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, Issuer Free Writing Prospectus, the Registration Statement (including the Rule 430B Information), the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any amendment or supplement thereto, 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 each Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that the Operating Partnership shall not be liable in any such case to the extent that any such loss, claim, damage or liability (or actions in respect thereof) 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, Issuer Free Writing Prospectus, 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 Operating Partnership by any Underwriter of the Notes through the Representatives expressly for use therein.

(b)    Indemnification of Operating Partnership. Each Underwriter, severally and not jointly, will indemnify and hold harmless the Operating Partnership, its officers who signed the

24

Registration Statement and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities to which any of the foregoing persons in this subsection (b) may become subject, under the 1933 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, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any amendment or supplement thereto, 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, Issuer Free Writing Prospectus, 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 Operating Partnership by such Underwriter through the Representatives expressly for use therein; and will reimburse such foregoing persons for any legal or other expenses reasonably incurred thereby in connection with investigating or defending any such action or claim as to which such foregoing persons shall be entitled to indemnification under this subsection (b) as such expenses are incurred. The Operating Partnership hereby acknowledges that the only information furnished to the Operating Partnership by any Underwriter through the Representatives expressly for use in any preliminary prospectus, any preliminary prospectus supplement, Issuer Free Writing Prospectus, the Registration Statement, the Prospectus, as amended or supplemented, or any other prospectus relating to the Notes, or any such amendment or supplement are the statements set forth in (i) the names of the Underwriters contained on the cover page and on the back page of the Prospectus and in the table under the caption “Underwriting (Conflicts of Interest)” in the Prospectus and (ii) the seventh, ninth and tenth paragraph under the caption “Underwriting (Conflicts of Interest)” in the Prospectus.

(c)    Actions Against Parties; Notification. Promptly after receipt by an indemnified party under subsection (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 (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

25

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, 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.

SECTION 7    Contribution.

If the indemnification provided for in Section 6 is unavailable to or insufficient to hold harmless an indemnified party under subsection 6(a) or 6(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 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 SECTION 6(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 but also the relative fault of 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 Operating Partnership on the one hand and such Underwriters on the other, in connection with the offering of the Notes pursuant to this Agreement, shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Notes (before deducting expenses) received by the Operating Partnership, and the total underwriting discounts and commissions received by the Underwriters, bear to the aggregate initial public offering price of the Notes.

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 Operating Partnership on the one hand or 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 and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 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 7. 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 7 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.

26

Notwithstanding the provisions of this Section 7, no Underwriter shall 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 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 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

The obligations of the Underwriters in this Section 7 to contribute are several in proportion to their respective underwriting obligations with respect to the Notes and not joint.

The obligations of the Operating Partnership under this Section 7 shall be in addition to any liability which the Operating Partnership may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls any Underwriter within the meaning of the 1933 Act; and the obligations of the Underwriters under this Section 7 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 of the Operating Partnership who signed the Registration Statement, and to each person, if any, who controls the Operating Partnership within the meaning of the 1933 Act.

SECTION 8    Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Operating Partnership or the Company, or authorized representatives of the Operating Partnership or the Company submitted pursuant hereto shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Underwriter or its affiliates or selling agents, any person controlling any Underwriter, its officers or directors or any person controlling the Operating Partnership or the Company, and (ii) delivery of and payment for the Notes.

SECTION 9    Termination.

(a)    Termination; General. The Representatives may terminate this Agreement, by notice to the Operating Partnership, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement, any Material Adverse Effect, whether or not arising in the ordinary course of business, the effect of which is such as to make it, in the reasonable judgment of the Underwriters, impracticable or inadvisable to proceed with the offering or delivery of the Notes as contemplated in the Registration Statement, the Prospectus or the General Disclosure Package, or (ii) if there has occurred (A) any material adverse change in the financial markets in the United States or the international financial markets, (B) any outbreak of hostilities or escalation thereof or other calamity or crisis, (C) a declaration by the United States of a national emergency or war, or (D) any change or development involving a prospective change in national or international political, financial, or economic conditions, in each case, the

27

effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Notes or to enforce contracts for the sale of the Notes, or (iii) (x) if trading in any securities of the Company or the Operating Partnership has been suspended or materially limited by the Commission or the NYSE, or (y) if trading generally on the NYSE, the Nasdaq Global Market or the NYSE American or in the over-the-counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by such system or by order of the Commission, FINRA or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal, New York or Delaware authorities, or (v) a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred, or (vi) if the rating assigned by any nationally recognized statistical rating organization to any debt securities of the Operating Partnership as of the date hereof shall have been downgraded, or withdrawn, since such date or if any such rating organization shall have publicly announced that it has placed any series of debt securities of the Operating Partnership under surveillance or review as to the rating of such debt securities or any of the Operating Partnership’s other securities, which does not indicate affirmation or improvement in the rating.

(b)    Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided, further, that Sections 1, 6, 7, 8, 9, 13 and 14 hereof shall survive such termination and remain in full force and effect.

SECTION 10    Default by One or More of the Underwriters.

(a)    Effect of Default by One or More of the Underwriters. If any Underwriter shall default in its obligation to purchase the Notes which it has agreed to purchase at the Closing Time under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Notes on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Notes, then the Operating Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Notes 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 Notes, or the Operating Partnership notifies the Representatives that it has so arranged for the purchase of such Notes, the Representatives or the Operating Partnership shall have the right to postpone the Closing Time for such Notes 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, as amended or supplemented, 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 10 with like effect as if such person had originally been a party to this Agreement with respect to such Notes.

(b)    Effect of Default to Non-Defaulting Underwriter. If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate

28

principal amount of such Notes which remains unpurchased does not exceed one-tenth of the aggregate principal amount of the Notes to be purchased at the Closing Time, then the Operating Partnership shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes which such Underwriter agreed to purchase at the Closing Time under this Agreement relating to such Notes and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the principal amount of Notes which such Underwriter agreed to purchase under this Agreement) of the Notes 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)    Termination Pursuant to Default. If, after giving effect to any arrangements for the purchase of the Notes of a defaulting Underwriter or Underwriters by the Representatives and the Operating Partnership as provided in subsection (a) above, the aggregate principal amount of Notes which remains unpurchased exceeds one-tenth of the aggregate principal amount of the Notes to be purchased at the Closing Time, 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 Notes of a defaulting Underwriter or Underwriters, then, in the case of a failure to purchase Notes at the Closing Time, this Agreement relating to such Notes 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 4(a) hereof and the indemnity and contribution agreements in Section 6 and Section 7 hereof, but nothing herein shall relieve a defaulting Underwriter from liability for its default.

In the event that any Underwriter that is a Covered Entity (as defined below) becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.
