UNDERWRITING AGREEMENT

April 26, 2011

▇▇▇▇▇▇▇, ▇▇▇▇▇ & Co.

▇▇▇ ▇▇▇▇ ▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

LaSalle Hotel Properties, a Maryland real estate investment trust (the “Company”), and LaSalle Hotel Operating Partnership, L.P., a Delaware limited partnership (the “Operating Partnership”), confirm their agreement with ▇▇▇▇▇▇▇, Sachs & Co. (the “Underwriter”), with respect to the issue and sale by the Company and the purchase by the Underwriter of 7,000,000 of the Company’s common shares of beneficial interest, par value $.01 per share (the “Common Shares”), and with respect to the grant by the Company to the Underwriter, of the option described in Section 2(b) hereof to purchase all or any part of the 1,050,000 additional Common Shares. The aforesaid 7,000,000 Common Shares (the “Initial Securities”) to be purchased by the Underwriter and all or any part of the 1,050,000 Common Shares subject to the option described in Section 2(b) hereof (the “Option Securities”) to be purchased by the Underwriter are hereinafter collectively called the “Securities.”

The Company has filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form S-3 (No. 333-163296), including the related base prospectus, covering the registration of the offer and sale of certain securities, including the Securities, under the Securities Act of 1933, as amended (the “1933 Act”) and the rules and regulations promulgated thereunder (the “1933 Act Regulations”), which automatic shelf registration statement became effective under Rule 462(e) under the 1933 Act Regulations. Promptly after execution and delivery of this Agreement, the Company will prepare and file a prospectus supplement 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 at the time it became effective but that is deemed to be part of and included in such registration statement pursuant to Rule 430B is referred to as “Rule 430B Information.” Each base prospectus and prospectus supplement used in connection with the offering of the Securities that omitted Rule 430B Information is hereinafter collectively called a “preliminary prospectus.” Such registration statement, at any given time, including the amendments thereto to 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”; provided, however, that “Registration Statement” without reference to a time means the Registration Statement as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of the Registration Statement with respect to the Underwriter and the Securities (within the meaning of Rule 430B(f)(2) of the 1933 Act Regulations (“Rule 430B(f)(2)”)); and provided, further, that if the Company files a registration statement with the Commission pursuant to Rule 462(b) of the 1933 Act Regulations relating to the Securities (the “Rule 462(b) Registration Statement”), then, after such filing, all references to “Registration Statement” shall also be deemed to include the Rule 462(b) Registration Statement. The Registration Statement at the time it originally became effective is herein called the “Original Registration Statement.” The base prospectus and the final prospectus supplement, in the form first furnished to the Underwriter for use in connection with the offering of the Securities, 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 hereinafter collectively called the “Prospectus.” For purposes of this Agreement, all references to the Registration Statement, any preliminary prospectus or the Prospectus or any amendment or supplement to any of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval system (“▇▇▇▇▇”).

The Company will contribute the net proceeds from the sale of the Securities to the Operating Partnership, and in exchange therefor, at the Closing Time (as defined in Section 2(c)) or any Date of Delivery (as defined in Section 2(b)), as applicable, the Operating Partnership will issue to the Company common units of limited partnership interest in the Operating Partnership (“Units”).

All references in this Agreement to financial statements and schedules and other information which is “contained,” “included” or “stated” in the Registration Statement, any preliminary prospectus or the Prospectus (or other references of like import) shall be deemed to include all such financial statements and schedules and other information 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, any preliminary prospectus or the Prospectus, as the case may be, at the time of execution of this Agreement; and all references in this Agreement to amendments or supplements to the Registration Statement, any preliminary prospectus or the Prospectus shall be deemed to 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 or the Prospectus, as the case may be, after the execution of this Agreement.

The term “Subsidiary” means a corporation, partnership, limited liability company or other entity, a majority of the outstanding voting or capital stock, partnership, membership or other voting or equity interests or general partnership interests, as the case may be, of which is owned or controlled, directly or indirectly, by the Company, the Operating Partnership or one or more other Subsidiaries of the Company or the Operating Partnership.

At the respective times the Original Registration Statement and any amendment thereto became effective, at each deemed effective date with respect to the Underwriter and the Securities pursuant to Rule 430B(f)(2), at the Closing Time and at each Date of Delivery (if any), the Registration Statement complied, complies 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.

The Prospectus and each amendment or supplement thereto, if any, at the time the Prospectus or any such amendment or supplement is issued, at the Closing Time and at each Date of Delivery (if any), complied, complies and will comply in all material respects with the requirements of the 1933 Act and the 1933 Act Regulations, and neither the Prospectus nor any amendments or supplements thereto, at the time the Prospectus or any such amendment or supplement was issued, at the Closing Time or at any Date of Delivery, included, includes 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.

Each preliminary prospectus (including the base prospectus or prospectuses filed as part of the Original Registration Statement or any amendment thereto) complied when so filed in all material respects with the 1933 Act Regulations.

This Agreement and the transactions contemplated herein have been duly authorized by the Company and the Operating Partnership, and this Agreement has been duly executed and delivered by the Company and the Operating Partnership and constitutes a valid and binding obligation of the Company and the Operating Partnership enforceable in accordance with its terms except to the extent that the indemnification provisions hereof may be limited by federal or state securities laws and public policy considerations in respect thereof and except as enforcement may be limited by bankruptcy, reorganization, moratorium or similar laws affecting creditors’ rights generally and general principles of equity.

(xvi) Absence of Defaults and Conflicts. None of the Company, the Operating Partnership or any Subsidiary is (A) in violation of its declaration of trust, partnership agreement, charter, by-laws or other governing instrument (“Governing Instruments”) or (B) in default in the performance or observance of any obligation, agreement, covenant or condition contained in any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or other agreement or instrument to which the Company, the Operating Partnership or any Subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company, the Operating Partnership or any Subsidiary is subject (collectively, “Agreements and Instruments”) or (C) in violation of any applicable law, statute, rule, regulation, judgment, order, writ or decree of any government, government instrumentality or court, domestic or foreign, having jurisdiction over the Company, the Operating Partnership or any Subsidiary or any of their assets, properties or operations (“Laws”), except for such violations or defaults of any Agreements and Instruments or Laws that would not result in a Material Adverse Effect. The execution, delivery and performance of this Agreement and the consummation of the transactions contemplated herein and in the Disclosure Package and the Prospectus (including the issuance and sale of the Securities and the use of the proceeds from the sale of the Securities as described in the Disclosure Package and the Prospectus under the caption “Use of Proceeds”) and compliance by the Company and the Operating Partnership with their respective obligations hereunder have been duly authorized by all necessary corporate or limited partnership action and do not and will not, whether with or without the giving of notice or passage of time or both, conflict with or constitute a breach of, or default or Repayment Event (as defined below) under, or

result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company, the Operating Partnership or any Subsidiary pursuant to, the Agreements and Instruments or Laws (except for such conflicts, breaches, defaults or Repayment Events or liens, charges or encumbrances that would not result in a Material Adverse Effect), nor will such action result in any violation of the provisions of the Governing Instruments of the Company, the Operating Partnership or any Subsidiary or of any Laws, except for such violations that would not have a Material Adverse Effect. As used herein, a “Repayment Event” means any event or condition which gives the holder of any note, debenture or other evidence of indebtedness (or any person acting on such holder’s behalf) the right to require the repurchase, redemption or repayment of all or a material portion of such indebtedness by the Company, the Operating Partnership or any Subsidiary.

(xvii) Absence of Labor Dispute. No labor dispute with the employees of the Company, the Operating Partnership or any Subsidiary exists or, to the knowledge of the Company or the Operating Partnership, is imminent, and the Company and the Operating Partnership are not aware of any existing or imminent labor disturbance by the employees of any of their or any Subsidiary’s principal suppliers, manufacturers, customers or contractors, which, in either case, may reasonably be expected to result in a Material Adverse Effect.

(xviii) Absence of Proceedings. There is no action, arbitration, suit, proceeding, inquiry or investigation before or brought by any arbitrator or court or governmental agency or body, domestic or foreign, now pending, or, to the knowledge of the Company or the Operating Partnership, threatened, against or affecting the Company, the Operating Partnership or any Subsidiary, which is required to be disclosed in the Registration Statement, the Disclosure Package or the Prospectus (other than as disclosed therein), or which might reasonably be expected to result in a Material Adverse Effect or which might materially and adversely affect the consummation of the transactions contemplated in this Agreement or the performance by the Company or the Operating Partnership of their respective obligations hereunder. The aggregate of all pending legal or governmental proceedings to which the Company, the Operating Partnership or any Subsidiary is a party or of which any of their respective properties or assets is the subject which are not described in the Registration Statement, the Disclosure Package and the Prospectus, including ordinary routine litigation, could not reasonably be expected to result in a Material Adverse Effect.

(xix) Accuracy of Exhibits. There are no contracts or documents which are required to be described in the Registration Statement, the Disclosure Package or the Prospectus or the documents incorporated by reference therein or to be filed as exhibits thereto which have not been so described and filed as required.

(xx) REIT Qualification. Commencing with its taxable year ended December 31, 1998, the Company has been, and upon the sale of the Securities, the Company will continue to be, organized and operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”), and the Company’s

present and proposed method of operation as described in the Registration Statement, the Disclosure Package and the Prospectus will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code.

SECTION 3 Covenants of the Company. Each of the Company and the Operating Partnership covenants with the Underwriter as follows:

(a) Compliance with Securities Regulations and Commission Requests. The Company, subject to Section 3(b), will comply with the requirements of Rule 430B and will notify the Underwriter immediately, and confirm the notice in writing, (i) when any post-effective amendment to the Registration Statement or new registration statement relating to the Securities 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 the Prospectus, or of the suspension of the qualification of the Securities 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(d) or 8(e) of the 1933 Act concerning the Registration Statement and (v) if the Company becomes the subject of a proceeding under Section 8A of the 1933 Act in connection with the offering of the Securities. 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 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 Company will make every reasonable effort to prevent the issuance of any stop, prevention or suspension order and, if any such order is issued, to obtain the lifting thereof at the earliest possible moment.

(b) Filing of Amendments and Exchange Act Documents. Until the distribution of the Securities by the Underwriter is complete, the Company will give the Underwriter notice of its

intention to file or prepare any amendment to the Registration Statement or new registration statement relating to the Securities or any amendment or supplement to any preliminary prospectus (including the base 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 Company will furnish the Underwriter 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 Underwriter or counsel for the Underwriter shall reasonably object. The Company agrees, during the period when a prospectus is required to be delivered under the 1933 Act (or but for the exception afforded by Rule 172 of the 1933 Act Regulations would be required to be delivered), to 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. The Company has given the Underwriter notice of any filings made pursuant to the 1934 Act or 1934 Act Regulations within 48 hours prior to the Initial Sale Time.

(c) Delivery of Registration Statements. The Company has furnished or will on request deliver to the Underwriter and counsel for the Underwriter, without charge, one signed copy of the Original Registration Statement and of each amendment thereto (including conformed copies of 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 on request deliver to the Underwriter, without charge, a conformed copy of the Original Registration Statement and of each amendment thereto (without exhibits). The copies of the Original Registration Statement and each amendment thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(d) Delivery of Prospectuses. The Company has delivered to the Underwriter, without charge, as many copies of each preliminary prospectus as the Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to the Underwriter, without charge, during the period when a prospectus is required to be delivered under the 1933 Act (or but for the exception afforded by Rule 172 of the 1933 Act Regulations would be required to be delivered), such number of copies of the Prospectus (as amended or supplemented) as the Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to ▇▇▇▇▇, except to the extent permitted by Regulation S-T.

(e) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 1934 Act Regulations so as to permit the completion of the distribution of the Securities as contemplated in this Agreement, the Disclosure Package and in the Prospectus. If at any time when a prospectus is required by the 1933 Act to be delivered (or but for the exception afforded by Rule 172 of the 1933 Act Regulations would be required to be delivered) in connection with sales of the Securities by the Underwriter or a dealer, any event shall occur or condition shall exist as a result of which it is necessary, in the opinion of counsel for the Underwriter or for the Company, to amend the Registration Statement or amend or supplement the Disclosure Package or the Prospectus in

order that the same 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 not misleading (in the case of the Disclosure Package and the Prospectus, 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 Disclosure Package or the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, subject to Section 3(b), such amendment, supplement or new registration statement as may be necessary to correct such statement or omission or to comply with such requirements, the Company will use its best 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 Securities) and the Company will furnish to the Underwriter such number of copies of such amendment, supplement or new registration statement as the Underwriter may reasonably request. If, prior to the completion of the public offer and sale of the Securities, at any time following the 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 Securities) or if any Issuer Free Writing Prospectus includes 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 prevailing at that subsequent time, not misleading, the Company will promptly notify the Underwriter 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.

(f) Permitted Free Writing Prospectuses. The Company agrees that, unless it obtains the prior written consent of the Underwriter, and the Underwriter agrees that, unless it obtains the prior consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the 1933 Act). Any such free writing prospectus consented to by the Company and the Underwriter, which includes each Issuer Free Writing Prospectus listed on Schedule A hereto, is hereinafter referred to as a “Permitted Free Writing Prospectus”. The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the 1933 Act Regulations applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping. Notwithstanding the foregoing, the Company consents to the use by the Underwriter of a free writing prospectus that contains only (a)(i) information describing the preliminary terms of the Securities or their offering, (ii) information meeting the requirements of Rule 134 of the 1933 Act Regulations or (iii) information that describes the final terms of the Securities or their offering or (b) other customary information that is neither “issuer information,” as defined in Rule 433, nor otherwise an Issuer Free Writing Prospectus.

(g) Blue Sky Qualifications. The Company will use its best efforts, in cooperation with the Underwriter, to qualify the Securities for offering and sale under the applicable securities laws of such states and other jurisdictions as the Underwriter 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 Company shall not be obligated to file any general consent to service of process or to qualify as a foreign corporation or as a dealer in securities in any jurisdiction in which it is not so qualified 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 Securities 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 a period of not less than one year from the date of this Agreement.

(h) Rule 158. The Company will 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 for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

(i) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified under the caption “Use of Proceeds” in the Disclosure Package and the Prospectus.

(j) REIT Qualification. The Company will use its best efforts to continue to meet the requirements for qualification as a REIT under the Code for each of its taxable years for so long as the Board of Trustees deems it in the best interests of the Company’s securityholders to remain so qualified.

(k) No Manipulation of Market for Securities. Except for the authorization of actions permitted to be taken by the Underwriter as contemplated herein or in the Registration Statement, the Disclosure Package and the Prospectus, neither the Company nor the Operating Partnership has or will (i) take, directly or indirectly, any action designed to cause or to result in, or that might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Securities, and (ii) until the 30^th day following the Closing Time, (A) sell, bid for or purchase the Securities or pay any person any compensation for soliciting purchases of the Securities or (B) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Company.

(l) NYSE Listing. The Company will use its best efforts to cause the Securities to be approved for listing, subject to official notice of issuance, on the NYSE prior to the Closing Time and each Date of Delivery (if any).

(m) Lock-Up Agreement. For a period of 30 days after the date of the Prospectus, the Company will not directly or indirectly, (i) offer, pledge, sell, or contract to sell any Common Shares, (ii) sell any option or contract to sell any Common Shares, (iii) purchase any option or contract to sell any Common Shares, (iv) grant any option, right or warrant to purchase any Common Shares, (v) enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any Common Shares whether any such swap or transaction is to be settled by delivery of Common Shares or other securities, in cash or otherwise, (vi) take any of the foregoing actions with respect to any securities convertible into or exchangeable or exercisable for or repayable with Common Shares, (vii) except as expressly provided for in this section, file with the Commission a registration statement under the 1933 Act

relating to any additional Common Shares or securities convertible into or exchangeable or exercisable for Common Shares, or (viii) publicly disclose the intention to take any of the foregoing actions, without the prior written consent of the Underwriter; provided, however, that the Company shall not be restricted from issuing Common Shares or options, warrants, partnership units or other securities convertible into Common Shares (A) upon the exercise of outstanding employee share options and options pursuant to employee benefit plans, (B) pursuant to non-employee trustee share plans, (C) pursuant to any dividend reinvestment plan of the Company, (D) pursuant to the Company’s 2009 Equity Incentive Plan, or (E) upon conversion of any currently outstanding convertible securities, and shall not be restricted from issuing Units or preferred units of limited partnership interest in the Operating Partnership as full or partial consideration for the acquisition from a third party of properties directly or indirectly by the Company or one of its Subsidiaries; or from filing a registration statement under the 1933 Act covering the resale of the shares into which such Units or preferred units of limited partnership interest in the Operating Partnership are convertible.

(n) Information Furnished by the Underwriter. The Company acknowledges that the information in (i) the second sentence of the first paragraph and (ii) the first two sentences of the second paragraph under the caption “Underwriting—Price Stabilization and Short Positions” in the Prospectus constitutes the only information furnished by the Underwriter as such information is referred to in Sections 1(a)(i), 1(a)(v), 6(a) and 6(b) hereof.

(o) Disclaimer of Fiduciary Relationship. The Company and the Operating Partnership acknowledge and agree that (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Securities and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Operating Partnership, on the one hand, and the Underwriter, on the other hand, (ii) in connection with the offering contemplated by this Agreement and the process leading to such transaction, the Underwriter is and has been acting solely as principal and not as the agent or fiduciary of the Company and the Operating Partnership or their securityholders, creditors, employees or any other party, (iii) the Underwriter has not assumed nor will it assume an advisory or fiduciary responsibility in favor of the Company or the Operating Partnership with respect to the offering of the Securities contemplated by this Agreement or the process leading thereto (irrespective of whether the Underwriter has advised or is currently advising the Company or the Operating Partnership on other matters) and the Underwriter has no obligation to the Company or the Operating Partnership with respect to the offering of the Securities contemplated by this Agreement except the obligations expressly set forth in this Agreement, (iv) the Underwriter and its affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company and the Operating Partnership, and (v) the Underwriter has not provided any legal, accounting, regulatory or tax advice with respect to the offering contemplated by this Agreement and the Company and the Operating Partnership have consulted their own legal, accounting, regulatory and tax advisors to the extent they deemed appropriate.

(p) Renewal of Registration Statement. The date of this Agreement is not more than three years subsequent to the initial effective date of the Registration Statement (the “Renewal Date”). If, immediately prior to the third anniversary of the Renewal Date, any Securities remain unsold by the Underwriter and a prospectus is required to be delivered or made available by the

Underwriter under the 1933 Act or the 1934 Act in connection with the sale of such Securities, the Company will, prior to the Renewal Date and subject to Section 3(b), file, if it has not already done so, a new shelf registration statement or, if applicable, an automatic shelf registration statement relating to such Securities, and, if such registration statement is not an automatic shelf registration statement, will use its best efforts to cause such registration statement to be declared effective within 180 days after the Renewal Date, and will take all other reasonable actions necessary or appropriate to permit the public offer and sale of such Securities to continue as contemplated in the expired registration statement relating to such Securities. References herein to the “Registration Statement” shall include such new shelf registration statement or automatic shelf registration statement, as the case may be.

SECTION 4 Payment of Expenses.

SECTION 6 Indemnification.

(a) Indemnification of the Underwriter. Each of the Company and the Operating Partnership agrees, jointly and severally, to indemnify and hold harmless the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, and any director, officer, employee or affiliate thereof as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred by the Underwriter or any such person, 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 Disclosure Package, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto), or the omission or alleged omission therefrom of a material fact required to be stated therein or 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, by the Underwriter or any such person, 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 any such settlement is effected with the written consent of the Company; and

(iii) against any and all expense whatsoever, as incurred by the Underwriter or any such person (including the fees and disbursements of counsel chosen by the Underwriter), 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 Underwriter expressly for use in the Registration Statement (or any amendment thereto), including the Rule 430B Information, any Issuer Free Writing Prospectus, the Disclosure Package, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto). The Company and the Operating Partnership acknowledge that such information consists only of the information described in Section 3(n) herein.

(b) Indemnification of the Company, the Operating Partnership, Trustees and Officers. The Underwriter agrees to indemnify and hold harmless the Company and the Operating Partnership, 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, and any officer, director, trustee, employee or affiliate thereof, 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 Disclosure Package, any preliminary prospectus or the Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use therein. The Company and the Operating Partnership acknowledge that such information consists only of the information described in Section 3(n) herein.

(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 that it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Underwriter, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. 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 (x) 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 and (y) the indemnifying party confirms in writing its indemnification obligations hereunder with respect to such settlement, compromise or judgment.

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 and the Operating Partnership, on the one hand, and the Underwriter, on the other hand, from the offering of the Securities pursuant to this Agreement 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 and the Operating Partnership, on the one hand, and of the Underwriter, on the other hand, in connection with the statements or omissions that resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

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

The relative fault of the Company and the Operating Partnership, on the one hand, and the Underwriter, 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 the Operating Partnership or by the Underwriter and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company, the Operating Partnership and the Underwriter 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, the Underwriter shall not be required under this Agreement to contribute any amount in excess of the amount of the underwriting discount applicable to the Securities purchased by it hereunder.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the ▇▇▇▇ ▇▇▇) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each director, officer, employee or affiliate of the Underwriter and each person, if any, who controls the 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 the Underwriter, and 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, subject in each case to the preceding two paragraphs.

For purposes of this Section 7, the Company and the Operating Partnership shall be deemed one party, jointly and severally liable for any obligations hereunder.

SECTION 8 Representations, Warranties and Agreements to Survive. All representations, warranties and agreements contained in this Agreement or in certificates of officers of the Company or the Operating Partnership submitted pursuant hereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or any controlling person, or by or on behalf of the Company or the Operating Partnership, and shall survive delivery of the Securities to the Underwriter and shall survive the termination of this Agreement.

SECTION 9 Termination of Agreement.

(a) Termination; General. The Underwriter may, without liability, terminate this Agreement, by notice to the Company, at any time at or prior to the Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Registration Statement, the Disclosure Package or the Prospectus, any material adverse change in the condition, financial or otherwise, or in the properties, earnings, business affairs or business prospects of the Company, the Operating Partnership and the Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States, any outbreak of hostilities or escalation thereof, any acts of terrorism involving the United States or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the sole judgment of the Underwriter, impracticable to market the Securities or inadvisable to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the NYSE, or if trading generally on the NYSE or in the Nasdaq Global Market has been suspended or materially 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 a material disruption has occurred in commercial banking or securities settlement or clearance services in the United States, or (iv) if a banking moratorium has been declared by either federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section, 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 and 14 shall survive such termination and remain in full force and effect.

SECTION 10 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 and confirmed to the receiving party.

SECTION 11 Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriter, the Company and the Operating Partnership and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriter, the Company and the Operating Partnership and their respective successors and the controlling persons and officers, trustees and directors referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein

contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriter, the Company and the Operating Partnership and their respective successors, and said controlling persons and officers, trustees and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Securities from the Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 12 Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the underwriter is required to obtain, verify and record information that identifies its clients, including the Company, which information may include the name and address of its clients, as well as other information that will allow the underwriter to properly identify its clients.
