(“Citigroup”), RBC Capital Markets, LLC (“RBC”), UBS Securities LLC (“UBS”) and Wells Fargo Securities, LLC (“Wells Fargo”) and each of the other Underwriters named in Schedule A hereto (collectively, the “Underwriters,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), for whom Citigroup, RBC, UBS and Wells Fargo are acting as representatives (in such capacity, the “Representatives”), with respect to the issue and sale by the Company and the purchase by the Underwriters, acting severally and not jointly, of the respective principal amounts set forth in said Schedule A (plus such additional principal amounts of notes each Underwriter may be obligated to purchase pursuant to Section 10 hereof) of $200,000,000 aggregate principal amount of the Company’s 4.500% Senior Notes due 2023 (the “2023 Notes”), which will be part of the same series of notes as the $300,000,000 aggregate principal amount of the 2023 Notes issued by the Company on June 6, 2013 (the “Previously Issued 2023 Notes”), and $400,000,000 aggregate principal amount of the Company’s 4.950% Senior Notes due 2027 (the “2027 Notes,” and together with the 2023 Notes, the “Notes”). The 2023 Notes are to be issued pursuant to an indenture dated as of February 25, 1998 and a supplemental indenture relating to the Previously Issued 2023 Notes (together, the “1998 Indenture”), each between the Company and U.S. Bank National Association, a national banking organization organized and existing under the laws of the United States, as trustee (the “Trustee”). The 2027 Notes are to be issued pursuant to an indenture dated as of February 3, 2016 and a supplemental indenture relating to the 2027 Notes (the “2016 Indenture,” and

together with the 1998 Indenture, the “Indentures”), each between the Company and the Trustee.

The Company understands that the Underwriters propose to make a public offering of the Notes as soon as the Representatives deem advisable after this Agreement has been executed and delivered.

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-206514) and post-effective amendment No. 1 thereto (“Post-Effective Amendment No. 1”), including a related prospectus. Such registration statement and Post-Effective Amendment No. 1, which cover the registration of various securities that may be issued from time to time by the Company, including the Notes, became effective under the Securities Act of 1933, as amended (the “1933 Act”) upon filing with the Commission pursuant to Rule 462(e) (“Rule 462(e)”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement relating to the Notes in accordance with the provisions of Rule 430B (“Rule 430B”) of the 1933 Act Regulations and paragraph (b) of Rule 424 (“Rule 424(b)”) of the 1933 Act Regulations. Any information included in such prospectus supplement that was omitted from such registration statement, as amended by Post-Effective Amendment No. 1 at the time Post-Effective Amendment No. 1 became effective but that is deemed to be a part of and included in the registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Each prospectus used in connection with the offering of the Notes that omitted Rule 430B Information is herein called a “preliminary prospectus.” Such registration statement, at any given time, including the amendments thereto (including Post-Effective Amendment No. 1) at such time, the exhibits and any schedules thereto at such time, the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at such time and the documents otherwise deemed to be a part thereof or included therein by the 1933 Act Regulations, is herein called the “Registration Statement.” The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The final prospectus, in the form furnished to the Underwriters for use in connection with the offering of the Notes, including the documents incorporated by reference therein pursuant to Item 12 of Form S-3 under the 1933 Act at the time of the execution of this Agreement, is herein called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus, the Prospectus or any amendment or supplement to any of the foregoing (including Post-Effective Amendment No. 1) shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering Analysis and Retrieval system (“EDGAR”).

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, the Prospectus or the General Disclosure Package (as defined herein), or other references of like import, shall be deemed to mean and include all such financial statements and schedules and other information which are incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, any preliminary prospectus, the Prospectus or the General Disclosure Package, as the case may be; and all references in this Agreement to amendments or supplements to the Registration

Statement, any preliminary prospectus, the Prospectus or the General Disclosure Package shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “1934 Act”), which is incorporated by reference in or otherwise deemed by the 1933 Act Regulations to be a part of or included in the Registration Statement, such preliminary prospectus, the Prospectus or the General Disclosure Package, as the case may be.

The 305 hotels described in the preliminary prospectus, the Prospectus and the General Disclosure Package as being owned by the Company as of September 30, 2016 are collectively referred to herein as the “Hotels.” The 198 travel centers described in the preliminary prospectus, the Prospectus and the General Disclosure Package as being owned by the Company as of September 30, 2016 are collectively referred to herein as the “Travel Centers.”

SECTION 1. Representations and Warranties.

(a) Representations and Warranties by the Company. The Company represents and warrants to each of the Underwriters as of the date hereof, the Applicable Time referred to in Section 1(a)(1) hereof and as of the Closing Time referred to in Section 2(b) hereof, and agrees with each Underwriter, as follows:

(1) Compliance with Registration Requirements. (A) At the time of filing of each of the Original Registration Statement and Post-Effective Amendment No. 1, (B) at the time of the most recent amendment to the Registration Statement, if any, for the purposes of complying with Section 10(a)(3) of the 1933 Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the 1934 Act or form of prospectus), (C) at the time the Company or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c) of the 1933 Act Regulations) made any offer relating to the Notes in reliance on the exemption provided by Rule 163 of the 1933 Act Regulations (“Rule 163”) and (D) at the date hereof, the Company was and is a “well-known seasoned issuer” as defined in Rule 405 of the 1933 Act Regulations (“Rule 405”), including not having been and not being an “ineligible issuer” as defined 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 on a Rule 405 “automatic shelf registration statement”. The Company has not received from the Commission any notice pursuant to Rule 401(g)(2) of the 1933 Act Regulations objecting to the use of the automatic shelf registration statement form.

At the time of filing of each of the Original Registration Statement and Post-Effective Amendment No 1, at the earliest time thereafter that the Company or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) of the 1933 Act Regulations) of the Notes and at the date hereof, the Company was not and is not an “ineligible issuer,” as defined in Rule 405.

The Original Registration Statement became effective upon filing pursuant to Rule 462(e) and any post-effective amendment thereto, including Post-Effective Amendment No. 1, also became effective upon filing pursuant to Rule 462(e). No stop order suspending the effectiveness of the Registration Statement has been issued under

the 1933 Act and no proceedings for that purpose have been instituted or are pending or, to the knowledge of the Company, are threatened by the Commission, and any request on the part of the Commission for additional information has been complied with.

Any offer that is a written communication relating to the Notes made prior to the filing of the Original Registration Statement by the Company or any person acting on its behalf (within the meaning, for this paragraph only, of Rule 163(c) of the 1933 Act Regulations) has been filed with the Commission in accordance with the exemption provided by 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 1933 Act provided by Rule 163.

At the respective times the Original Registration Statement, Post-Effective Amendment No. 1 and any other amendment to the Registration Statement became effective, at each deemed effective date with respect to the Underwriters pursuant to Rule 430B(f)(2) of the 1933 Act Regulations and at the Closing Time, the Registration Statement complied and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and did not and will not 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 not misleading.

Neither the Prospectus nor any amendments or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued and at the Closing Time, included or will include an untrue statement of a material fact or omitted or will omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Any preliminary prospectus (and the prospectus or prospectuses filed as part of the Original Registration Statement, Post-Effective Amendment No. 1 or any other amendment to the Registration Statement) complied when so filed in all material respects with the 1933 Act and the 1933 Act Regulations and any such preliminary prospectus was and the Prospectus delivered to the Underwriters for use in connection with this offering 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.

As of the Applicable Time (as defined below), any Issuer Free Writing Prospectus (as defined below) issued at or prior to the Applicable Time and the Statutory Prospectus (as defined below), all considered together (collectively, the “General Disclosure Package”) did not include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

The representations and warranties in the preceding four paragraphs shall not apply to statements in or omissions from the Registration Statement or any post-effective amendment thereto, any preliminary prospectus, the Prospectus or any amendments or supplements thereto, or the General Disclosure Package made in reliance upon and in conformity with information furnished to the Company by the Underwriters through the

Representatives in writing expressly for use in the Registration Statement (including the prospectus filed with the Original Registration Statement and with Post-Effective Amendment No. 1) or any post-effective amendment thereto, any preliminary prospectus, the Prospectus, or any amendments or supplements thereto, or the General Disclosure Package.

Such disclosure controls and procedures (a) are designed to ensure that material information relating to the Company, including its consolidated subsidiaries, is made known to the Company’s Chief Executive Officer and its Chief Financial Officer (or persons performing similar functions), particularly during the periods in which the filings made by the Company with the Commission which it may make under Sections 13(a), 13(c), 14 or 15(d) of the 1934 Act are being prepared, (b) have been evaluated for effectiveness as of the end of the period covered by the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Commission and (c) are effective to perform the functions for which they were established. The Company’s independent registered public accounting firm and the audit committee of the board of trustees of the Company have been advised of (x) any significant deficiencies in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial data and (y) any fraud, whether or not material, that involves management or other employees who have a role in the Company’s internal control over financial reporting. The principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Company have made all certifications required by Sections 302 and 906 of the Sarbanes-Oxley Act and any related rules and regulations promulgated by the Commission, and the statements contained in any such certification were complete and correct as of the dates made. Since the date of the most recent evaluation of such disclosure controls and procedures, there have been no significant changes in the Company’s internal control over financial reporting or in other factors that have materially affected or are reasonably likely to materially affect the Company’s internal control over financial reporting.

(29) Good Standing of the Manager. Except as otherwise disclosed in the General Disclosure Package and the Prospectus, since the respective dates as of which information is given in the General Disclosure Package and the Prospectus there has been no material adverse change in the business, operations, earnings, prospects, properties or condition (financial or otherwise) of The RMR Group LLC (the “Manager”), whether or not arising in the ordinary course of business, that would have a Material Adverse Effect. The Second Amended and Restated Business Management Agreement, dated June 5, 2015, between the Company, the Manager and the other parties thereto, has been duly authorized, executed and delivered by the parties thereto and constitutes the valid agreement of the parties thereto, enforceable in accordance with its terms, except as limited by (a) the effect of bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer or other similar laws relating to or affecting the rights or remedies of creditors or (b) the effect of general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

(30) Periodic Reporting Requirements. The Company is subject to the reporting requirements of either Section 13 or Section 15(d) of the 1934 Act and files reports with the Commission on EDGAR.

There is and has been no failure on the part of the Company or, to the Company’s knowledge, any of the Company’s trustees or officers, in their capacities as such, to comply in any material respect with any applicable provision of the Sarbanes-Oxley Act and the rules and regulations promulgated by the Commission in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications.

(32) Foreign Corrupt Practices Act. Neither the Company nor, to the knowledge of the Company, any trustee, officer, agent, affiliate or other person acting on behalf of the Company or its subsidiaries has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA and the Company and, to the knowledge of the Company, its affiliates have conducted their businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(33) Money Laundering Laws. The operations of the Company are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements of the Currency and Foreign Transactions Reporting Act of 1970, as amended, the money laundering statutes of all jurisdictions, 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 the Company with respect to the Money Laundering Laws is pending or, to the knowledge of the Company, threatened.

(34) OFAC. Neither the Company nor, to the knowledge of the Company, any trustee, officer, agent, affiliate or person acting on behalf of the Company is currently subject to any U.S. sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Company will not directly or indirectly use the proceeds of the offering, 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 U.S. sanctions administered by OFAC.

(b) Officers’ Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries and delivered to the Underwriters or to counsel for the Underwriters in connection with the offering of the Notes shall be deemed a representation and warranty by the Company to the Underwriters as to the matters covered thereby on the date of such certificate.

SECTION 2. Sale and Delivery to the Underwriters; Closing.

(a) Notes. The commitments of the several Underwriters to purchase the Notes pursuant to the terms hereof shall be deemed to have been made on the basis of the representations, warranties and agreements herein contained and shall be subject to the terms and conditions herein set forth.

(b) Payment. The Company will deliver against payment of the purchase price of (i) 100.6025% of the principal amount of 2023 Notes, plus accrued interest for the period from and including December 15, 2016 to, but excluding, the date of delivery (if the Closing Date is January 13, 2017, aggregate accrued interest will be $700,000 with respect to the 2023 Notes to be purchased by the Underwriters) and (ii) 98.304% of the principal amount of 2027 Notes, plus accrued interest, if applicable, the 2023 Notes and the 2027 Notes, each in the form of a permanent global security in definitive form (each a “Global Security” and collectively the “Global Securities”) deposited with the Trustee, in its capacity as trustee for the 2023 Notes and the 2027 Notes, as applicable, as custodian for The Depository Trust Company (“DTC”) and registered in the name of Cede & Co., as nominee for DTC. Interests in the Global Securities will be held only in book-entry form through DTC, except in the limited circumstances described in the Prospectus. Payment for the Notes shall be made by the Underwriters in Federal (same day) funds by wire transfer to an account of the Company at a bank reasonably acceptable to the Representatives on January 13, 2017, or at such other time not later than ten full business days thereafter as the Representatives and the Company determine, such time being herein referred to as the “Closing Time”, against delivery to the Trustee, in its capacity as trustee for the 2023 Notes and the 2027 Notes, as applicable, as custodian for DTC of the Global Securities representing the 2023 Notes and the 2027 Notes. The Global Securities will be made available for checking at the office of Sullivan & Worcester LLP, Boston, Massachusetts, at least 24 hours prior to the Closing Time.

The Notes shall be issued in such authorized denominations and registered in such names as the Representatives shall request not later than one business day prior to the Closing Time. The Notes shall be made available for inspection not later than 10:00 a.m. (New York City time) on the business day prior to the Closing Time, at the office of The Depository Trust Company or its designated custodian.

SECTION 3. Covenants of the Company. The Company covenants with each Underwriter as follows:

(a) Immediately following the execution of this Agreement, the Company will prepare a Prospectus setting forth the aggregate principal amount of Notes covered thereby and their terms not otherwise specified in the preliminary prospectus, the name of each Underwriter, the price at which the Notes are to be purchased by the Underwriters from the Company, and such other information as the Representatives and the Company deem appropriate in connection with the offering of the Notes; and the Company 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 furnish to the Underwriters as many copies (including by electronic means, if so requested in lieu of paper copies) of the Prospectus as they shall reasonably request, including, if requested by the Underwriters, in addition to or in lieu thereof, electronic copies of

the Prospectus. The Company 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 and otherwise in accordance with Rules 456(b) and 457(r) of the 1933 Act Regulations.

(b) During the period beginning on the Applicable Time and ending on the later of the Closing Time or such date, as in the reasonable opinion of counsel for the Underwriters, the Prospectus is no longer required under the 1933 Act or the 1934 Act to be delivered in connection with sales by the Underwriters or a dealer, including in circumstances where such requirement may be satisfied pursuant to Rule 172 of the 1933 Act Regulations (the “Prospectus Delivery Period”), the Company will comply with the requirements of Rule 430B and will notify the Representatives immediately, and confirm the notice in writing, (i) of the transmittal to the Commission for filing of any amendment to the Registration Statement, (ii) of the transmittal to the Commission for filing of any supplement or amendment to the Prospectus or any document to be filed pursuant to the 1934 Act, (iii) of the receipt of any comments from the Commission with respect to the Registration Statement or Prospectus or documents incorporated or deemed to be incorporated by reference therein, (iv) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus with respect to the Notes or for additional information relating thereto, and (v) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the initiation of any proceedings for that purpose. The Company will make every reasonable effort to prevent the issuance of any such stop order and, if any stop order is issued, to obtain the lifting thereof at the earliest possible moment.

(c) During the Prospectus Delivery Period, prior to amending or supplementing the Registration Statement (including any filing under Rule 462(b) of the 1933 Act Regulations), any preliminary prospectus or the Prospectus (including any amendment or supplement through incorporation by reference of any report filed under the 1934 Act), the Company will furnish to the Representatives for review a copy of each such proposed amendment or supplement a reasonable amount of time prior to such proposed filing or use, as the case may be, and will not file any such amendment or supplement or use any such prospectus to which counsel for the Underwriters shall reasonably object. The Company has given the Representatives notice of any filings made pursuant to the 1934 Act or 1934 Act Regulations within 48 hours prior to the Applicable Time; the Company will give the Representatives notice of its intention to make any such filing from the Applicable Time to the Closing Time and will furnish the Representatives with copies of any such documents a reasonable amount of time prior to such proposed filing and will not file or use any such document to which the Representatives or counsel for the Underwriters shall reasonably object by written notice of the Representatives to the Company. The Company will prepare a final term sheet substantially in the form set forth in Schedule B hereto (the “Final Term Sheet”) reflecting the final terms of the Notes, 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 Company shall furnish the Representatives with copies of any 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 for the Underwriters shall reasonably object.

(d) Upon request, the Company will deliver to the Underwriters a conformed copy of the Original Registration Statement as originally filed, Post-Effective Amendment No. 1 and of

any other amendment to the Registration Statement filed prior to the termination of the initial offering of the Notes (including exhibits filed therewith or incorporated by reference therein and the documents incorporated by reference into the Prospectus pursuant to Item 12 of Form S-3).

(e) The Company will furnish to the Underwriters, from time to time during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, in connection with the offering, such number of copies (including by electronic means, if so requested by the Underwriters, in addition to or in lieu of, paper copies) of the Prospectus (as amended or supplemented) as the Underwriters may reasonably request for the purposes contemplated by the 1933 Act, the 1933 Act Regulations, the 1934 Act or 1934 Act Regulations.

(f) If at any time when a prospectus is required by the 1933 Act to be delivered in connection with the sale of the Notes after the date hereof any event shall occur as a result of which it is necessary, in the opinion of counsel for the Underwriters, which shall be communicated by the Underwriters through the Representatives in writing to the Company, to amend or supplement the Prospectus in order to make the Prospectus not misleading in the light of the circumstances existing at the time it is delivered, the Company will promptly either (i) forthwith prepare and furnish to the Underwriters an amendment of or supplement to the Prospectus or (ii) make an appropriate filing pursuant to Section 13, 14 or 15 of the 1934 Act, in each case, in form and substance reasonably satisfactory to counsel for the Underwriters, which will amend or supplement the Prospectus so that it will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is delivered, not misleading. If at any time after the date hereof, an event or development occurs as a result of which the General Disclosure Package contains an untrue statement of a material fact or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at the time it is used, not misleading, the Company will promptly notify the Representatives and will promptly amend or supplement in a manner reasonably satisfactory to the Representatives, at its own expense, the General Disclosure Package to eliminate or correct such untrue statement or omission. If at any time 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 Company 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. The Underwriters’ delivery of any such amendment or supplement shall not constitute a waiver of any of the conditions in Section 5 hereof.

(g) The Company represents and agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter agrees that, unless it obtains the prior written consent of the Company and the Representatives, 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, required to be filed with the Commission; provided, however, that prior to the preparation of the

Final Term Sheet in accordance with Section 3(c) 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 Company and the Representatives is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company represents that it has treated or agrees that it 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.

(h) The Company will endeavor in good faith, in cooperation with the Representatives, to qualify the Notes for offering and sale under the applicable securities laws and real estate syndication laws of such states and other jurisdictions of the United States as the Representatives may designate; provided that, in connection therewith, the Company shall not be required to qualify as a foreign corporation or trust or to file any general consent to service of process. In each jurisdiction in which the Notes have been so qualified the Company will file such statements and reports as may be required by the laws of such jurisdiction to continue such qualification in effect for so long as required for the distribution of the Notes.

(i) The Company will make generally available to its security holders as soon as reasonably practicable, but not later than 90 days after the close of the period covered thereby, an earning statement of the Company (in form complying with the provisions of Rule 158 of the 1933 Act Regulations) covering a period of at least twelve months beginning not later than the first day of the Company’s fiscal quarter next following the effective date of the Registration Statement. “Earning statement”, “make generally available” and “effective date” will have the meanings contained in Rule 158 of the 1933 Act Regulations.

(j) The Company will 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 the caption “Use of Proceeds” in all material respects.

(k) The Company currently intends to continue to qualify as a “real estate investment trust” under the Code, and use its best efforts to continue to meet the requirements for qualification as a “real estate investment trust” under the Code.

(l) The Company will timely file any document which it is required to file pursuant to the 1934 Act prior to the termination of the offering of the Notes.

(m) The Company will not offer, sell, contract to sell, pledge or otherwise dispose of, directly or indirectly, or file with the Commission a registration statement under the 1933 Act relating to debt securities issued or guaranteed by the Company and having a maturity of more than one year from the date of issue, or publicly disclose the intention to make any such offer, sale, pledge, disposition or filing, without the prior written consent of the Representatives for a period beginning at the date of this Agreement and ending at the later of the Closing Time or the lifting of trading restrictions by the Representatives. For the avoidance of doubt, this covenant does not prohibit draws under the Company’s existing $1 billion aggregate principal amount credit facility which matures in 2018 during the period specified in the foregoing sentence.

SECTION 4. Payment of Expenses.

(a) Expenses. The Company will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the preparation, printing, delivery and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment or supplement thereto, (ii) the preparation, issuance and delivery of the Notes and any certificates for the Notes to the Underwriters, including any transfer taxes and any stamp or other duties payable upon the sale, issuance or delivery of the Notes to the Underwriters, (iii) the fees and disbursements of the Company’s counsel, accountants and other advisors or agents, as well as the fees and disbursements of the Trustee and their respective counsel, (iv) the qualification of the Notes under state securities laws in accordance with the provisions of Section 3(h) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Company or the Underwriters in connection therewith and in connection with the preparation, printing and delivery of a Blue Sky Survey, and any amendment thereto, (v) the printing and delivery to the Underwriters of copies of the Prospectus, any preliminary prospectus, any Permitted Free Writing Prospectus and the Prospectus and any amendments or supplements thereto, (vi) any fees charged by any “nationally recognized statistical rating organization” (as that term is defined in Section 3(a)(62) under the 1934 Act, a “NRSRO”) for the rating of the Notes, (vii) the filing fees incident to, and the reasonable fees and disbursements of counsel for the Underwriters in connection with, the review, if any, by the Financial Industry Regulatory Authority, Inc.

At Closing Time, the Company shall have furnished counsel for the Underwriters with such documents and opinions as they may reasonably require for the purpose of enabling them to pass upon the issuance and sale of the Notes as herein contemplated, or in order to evidence the accuracy of any of the representations or warranties, or the fulfillment of any of the conditions, herein contained; and all proceedings taken by the Company in

connection with the issuance and sale of the Notes as herein contemplated shall be reasonably satisfactory in form and substance to the Representatives and counsel to the Underwriters.

(m) Termination of this Agreement. If any condition specified in this Section 5 shall not have been fulfilled when and as required to be fulfilled, this Agreement may be terminated by the Underwriters by notice to the Company at any time at or prior to the Closing Time, and such termination shall be without liability of any party to any other party except as provided in Section 4 hereof and except that Sections 1, 6, 7, 8 and 14 hereof shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of Underwriters. The Company agrees to indemnify and hold harmless each Underwriter, its officers, directors and agents, their affiliates, and each person, if any, who controls each Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the successors and assigns of all of the foregoing persons as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or any amendment thereto), including the Rule 430B Information, or the omission or alleged omission therefrom of a material fact required to be stated therein or necessary to make the statements therein not misleading or arising out of any untrue statement or alleged untrue statement of a material fact included in any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred (including the fees and disbursements of counsel chosen by the Underwriters), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives in writing expressly

for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto).

(b) Indemnification of Company, the Company’s Trustees and Officers. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless the Company, its trustees, each of its officers who signed the Registration Statement, their affiliates, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act and the successors and assigns of all of the foregoing persons, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), including the Rule 430B Information, any Issuer Free Writing Prospectus, the General Disclosure Package or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Underwriters through the Representatives in writing expressly for use therein.

(c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. The indemnifying party shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified parties and payment of all fees and expenses. The indemnified parties shall have the right to employ separate counsel in any such action and participate in the defense thereof, but the fees and expenses of such counsel shall be at the expense of the indemnified parties unless (i) the employment of such counsel shall have been specifically authorized in writing by the indemnifying party, (ii) the indemnifying party shall have failed to assume the defense and employ counsel or (iii) the named parties to any such action (including any impleaded parties) include both the indemnified parties and the indemnifying party and the indemnified parties shall have been advised by such counsel that there may be one or more legal defenses available to them which are different from or additional to those available to the indemnifying party (in which case the indemnifying party shall not have the right to assume the defense of such action on behalf of the indemnified parties, it being understood, however, that the indemnifying party shall not, in connection with any one such action or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) for the indemnified parties, which firm shall be designated in writing by the indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred). No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified

party from all liability arising out of such litigation, investigation, proceeding 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.

(d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) hereof effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, from the offering of the Notes pursuant hereto or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Company, on the one hand, and the Underwriters, on the other hand, in connection with the offering of the Notes pursuant hereto shall be deemed to be in the same respective proportions as the total net proceeds from the offering of such Notes (before deducting expenses) received by the Company and the total underwriting discount received by the Underwriters, in each case as set forth on the cover of the Prospectus, bear to the aggregate initial public offering price of such Notes as set forth on such cover.

The relative fault of the Company, on the one hand, and the Underwriters, on the other hand, shall be determined by reference to, among other things, whether any such untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company 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 or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in

investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

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 Underwriters has otherwise been required to pay by reason of any 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.

For purposes of this Section 7, each person, if any, who controls each Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, each trustee of the Company, each officer of the Company who signed the Registration Statement, and each person, if any, who controls the Company within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company. The Underwriters’ contribution obligations under this Section 7 are several, in proportion to their respective underwriting commitments, and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All representations, warranties and agreements contained in this Agreement of the Company or in certificates of officers of the Company or any of its subsidiaries submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriters or controlling persons, or by or on behalf of the Company, and shall survive delivery of and payment for the Notes.

SECTION 9. Termination.

(a) The Underwriters may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has occurred any change, or any development or event involving a prospective change since the respective dates as of which information is given in the Prospectus (exclusive of any supplement thereto) or the General Disclosure Package, in the condition (financial or other), business, properties or results of operations of the Company and its subsidiaries taken as one enterprise which, in the sole judgment of the Underwriters, is material and adverse and makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Notes; (ii) if any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls as would, in the judgment of the Representatives, be likely to prejudice materially the success of the proposed issuance, sale or distribution of the Notes, whether in the primary market or in respect of dealings in the secondary market; (iii) if trading in the Company’s Common Shares has been suspended by the Commission or The NASDAQ Stock Market LLC (the “NASDAQ”); (iv) if there has occurred any material suspension or material limitation of trading in securities generally on the NASDAQ, or any setting of minimum prices for trading on such

exchange, or any suspension of trading of any securities of the Company on any exchange or in the over-the-counter market; (v) if there has occurred any banking moratorium declared by U.S. Federal or New York authorities; (vi) if there has occurred any major disruption of settlements of securities or clearance services in the United States; (vii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the sole judgment of the Underwriters, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency makes it impractical or inadvisable to proceed with completion of the public offering or the sale of and payment for the Notes or (viii) if the ratings assigned to debt securities of the Company by any NRSRO, as of the date hereof shall have been lowered since such date or if any such rating organization shall have publicly announced that it has placed any debt securities of the Company on what is commonly termed a “watch list” for possible downgrading.

(b) 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 6 and 7 hereof shall survive such termination.

SECTION 10. Default by One or More of the Underwriters. If one or more of the Underwriters shall fail at the Closing Time to purchase the principal amount of 2023 Notes and/or 2027 Notes, as applicable, which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), then the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Notes in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(i) if the principal amount of Defaulted Notes does not exceed 10% of the aggregate principal amount of the 2023 Notes and/or the 2027 Notes, as the case may be, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii) if the principal amount of Defaulted Notes exceeds 10% of the aggregate principal amount of the 2023 Notes and/or the 2027 Notes, as the case may be, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company.

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, either the Representatives or the Company shall have the right to postpone the Closing Time for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements. As used herein, the term “Underwriter” includes any person substituted for an Underwriter under this Section 10.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication.

SECTION 12. No Fiduciary Relationship. The Company acknowledges and agrees that (i) the purchase and sale of the Notes pursuant to this Agreement, including the determination of the public offering price of the Notes and any related discounts and commissions, is an arm’s-

length commercial transaction, between the Company on the one hand, and the Underwriters, on the other hand, (ii) in connection with the offering contemplated hereby and the process leading to such transaction, each Underwriter is and has been acting solely as a principal and is not the agent or fiduciary of the Company or its shareholders, creditors, employees, or any other party, (iii) no Underwriter has assumed or will assume an advisory or fiduciary responsibility in favor of the Company with respect to the offering contemplated hereby or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company on other matters) and no Underwriter has any obligation to the Company with respect to the offering contemplated hereby except the obligations expressly set forth in this Agreement, (iv) the Underwriters and their respective affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company, and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the transaction contemplated hereby and the Company has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the parties hereto and their respective successors, and said controlling persons and officers and trustees and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.

SECTION 15. Waiver of Jury Trial. All parties hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.
