(jj) The Company and its subsidiaries (i) are in compliance with any and all applicable foreign, federal, state and local laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses and (iii) have not received notice of any actual or potential liability under any Environmental Laws, except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals, or liability would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Prospectus (exclusive of any supplement thereto). Except as set forth in the Disclosure Package and the Prospectus, neither the Company nor any of the subsidiaries has been notified that it has been named as a “potentially responsible party” under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended. Except as otherwise set forth in the Disclosure Package and the Prospectus, and except as would not individually or in the aggregate reasonably be expected to materially affect the value of such Property or interfere in any material respect with the use made and proposed to be made of such Property by the Company or any subsidiary, to the knowledge of the Company and the Operating Partnership, there have been no and are no (i) aboveground or underground storage tanks; (ii) polychlorinated biphenyls (“PCBs”) or PCB-containing equipment; (iii) asbestos or asbestos containing materials; (iv) lead based paints; (v) mold or other airborne contaminants; or (vi) dry-cleaning facilities in, on, under, or about any Property owned by the Company, the Operating Partnership or their subsidiaries.

(kk) In the ordinary course of its business, the Company periodically reviews the effect of Environmental Laws on the business, operations and properties of the Company and its subsidiaries, in the course of which it identifies and evaluates associated costs and liabilities (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, the Company has reasonably concluded that such associated costs and liabilities would not, singly or in the aggregate, reasonably be expected to have a Material Adverse Effect, except as set forth in or contemplated in the Disclosure Package and the Prospectus (exclusive of any supplement thereto).

(ll) Neither the Company nor any of its subsidiaries maintains or contributes to any “pension plan” (within the meaning of Section 3(2) of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”)) that is subject to Title IV of ERISA or any “multiemployer plan” (within the meaning of Section 4001(a)(3) of ERISA). Each “pension plan” (within the meaning of Section 3(2) of ERISA) maintained by the Company or any of its subsidiaries which is intended to be qualified under Section 401(a) of the Internal Revenue Code of 1986, as amended (the “Code”), has received a favorable determination or opinion letter from the Internal Revenue Service that such plan is so qualified, and, to the knowledge of the Company, nothing has occurred, whether by action or failure to act, that could reasonably be

expected to cause the loss of such qualification. Neither the Company nor any of its subsidiaries maintains or is required to contribute to a “welfare plan” (as defined in Section 3(1) of ERISA) which provides retiree or other post-employment welfare benefits or insurance coverage (other than “continuation coverage” (as defined in Section 602 of ERISA) or as otherwise required by applicable law). Each “employee benefit plan” (within the meaning of Section 3(3) of ERISA) established or maintained by the Company and/or one or more of its subsidiaries is in compliance with the currently applicable provisions of ERISA except for such failures to comply that would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

(mm) There is and has been no failure on the part of the Company and any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the Xxxxxxxx-Xxxxx Act of 2002 and the rules and regulations promulgated in connection therewith (the “Xxxxxxxx-Xxxxx Act”), including the establishment and maintenance of disclosure controls and procedures, Section 402 related to loans and Sections 302 and 906 related to certifications, except for such failures to comply that would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

(nn) Neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries is aware of or 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 (“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, its subsidiaries and, to the knowledge of the Company and the Operating Partnership, 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 except for such violations or failures to comply that would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

(oo) The operations of the Company and its subsidiaries 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 or any of its subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Company, threatened except for such failures to comply, actions, suits or proceedings that would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect.

(pp) Except as would not individually or in the aggregate reasonably be expected to have a Material Adverse Effect, neither the Company nor any of its subsidiaries nor, to the knowledge of the Company, any director, officer, agent, employee or affiliate of the Company or any of its subsidiaries 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.

(qq) Except as set forth in the Disclosure Package and the Prospectus, the Company and its subsidiaries have good and marketable title to all personal property owned by them, free and clear of all encumbrances and defects; and all personal property held under lease by the Company or any subsidiary is held by it under valid, subsisting and enforceable leases, in each case, with such exceptions as are not material and do not interfere with the use made and proposed to be made of such property by the Company or the subsidiary.

(rr) No relationship, direct or indirect, exists between or among the Company or its subsidiaries on the one hand, and the directors, officers, or shareholders of the Company on the other hand, which is required to be described in the Disclosure Package and the Prospectus and which is not so described.

(ss) Commencing with its taxable year ended December 31, 2004, the Company has been organized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (a “REIT”) under the Code, and its proposed method of operation will enable it to meet the requirements for qualification and taxation as a REIT under the Code. Each of the Company’s corporate subsidiaries qualifies as a “taxable REIT subsidiary” within the meaning of Section 856(l) of the Code and all applicable regulations under the Code.

(tt) The Operating Partnership is and has been at all times classified as a partnership or disregarded entity, and not as an association or partnership taxable as a corporation, for federal income tax purposes.

(uu) The Company and the Operating Partnership and each of their subsidiaries (including any predecessor entities) have not distributed, and prior to the later of five business days after the termination of this Agreement and the completion of the distribution of the Shares, will not distribute, any offering material in connection with the offering or sale of the Shares other than the Registration Statement and the Prospectus or any other materials, if any, permitted by the Securities Act.

Any certificate signed by any officer of either of the Transaction Entities and delivered to the Manager or counsel for the Manager in connection with the sale and offering of the Shares shall be deemed a representation and warranty by the Transaction Entities, as to matters covered thereby, to the Manager.

3. Sale and Delivery of Shares.

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell Shares from time to time through the Manager, acting as sales agent, and the Manager agrees to use its reasonable efforts to sell, as sales agent for the Company, the Shares on the following terms.

(i) The Shares are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the Manager on any day that (A) is a trading day for the NYSE, (B) the Company has instructed the Manager by telephone (confirmed promptly by electronic mail to the applicable individuals named on Schedule III hereto) to make such sales and (C) the Transaction Entities have satisfied their obligations under Section 6 of this Agreement. The Company will designate the maximum amount of the Shares to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Share at which such Shares may be sold. Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell on a particular day all of the Shares designated for the sale by the Company on such day. The gross sales price of the Shares sold under this Section 3(a) shall be the market price for shares of the Company’s Common Stock sold by the Manager under this Section 3(a) on the NYSE at the time of sale of such Shares (but in no event shall such gross price be less than the minimum price per Share designated by the Company at which such Shares may be sold).

(ii) Each of the Transaction Entities acknowledges and agrees that (A) there can be no assurance that the Manager will be successful in selling the Shares, (B) the Manager will incur no liability or obligation to the Transaction Entities or any other person or entity if it does not sell Shares for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Shares as required under this Agreement and (C) the Manager shall be under no obligation to purchase Shares on a principal basis pursuant to this Agreement.

(iii) The Company shall not authorize the issuance and sale of, and the Manager may not sell, any Share at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Directors (the “Board”), or a duly authorized committee thereof, and notified to the Manager in writing. The Company or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail to the applicable individuals named on Schedule III hereto), suspend the offering of the Shares for any reason and at any time (a “Suspension”); provided, however, that such Suspension shall not affect or impair the parties’ respective obligations with respect to the Shares sold hereunder prior to the giving of such notice.

(iv) The Manager hereby covenants and agrees not to make any sales of the Shares on behalf of the Company, pursuant to this Section 3(a), other than by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 (such transactions are hereinafter referred to as “At-the-Market Offerings”).

(v) The compensation to the Manager for sales of the Shares on any given day with respect to which the Manager acts as sales agent under this Agreement shall be at a mutually agreed rate, not to exceed 2.0% of the gross sales price of the Shares sold pursuant to this Section 3(a) on such day. The remaining proceeds, after further deduction for any documented transaction fees imposed on the Manager by any governmental or self regulatory organization in respect of such sales (the “Transaction Fees”), shall constitute the net proceeds to the Company for such Shares (the “Net Proceeds”).

(vi) The Manager shall provide written confirmation (which may be by electronic mail to the applicable individuals named on Schedule III hereto) to the Company following the close of trading on the NYSE each day in which the Shares are sold under this Section 3(a) setting forth the number of the Shares sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Transaction Entities, and the compensation payable by the Transaction Entities to the Manager with respect to such sales.

(vii) Settlement for sales of the Shares pursuant to this Section 3(a) will occur on the third business day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Shares sold through the Manager for settlement on such date shall be issued and delivered by the Company to the Manager against payment of the Net Proceeds for the sale of such Shares. Settlement for all such Shares shall be effected by free delivery of the Shares to the Manager’s account at The Depository Trust Company (“DTC”) in return for a payment equal to the Net Proceeds for the sale of such Shares in same day funds delivered to the account designated by the Company. If the Company or its transfer agent (if applicable) shall default on its obligation to deliver the Shares on any Settlement Date, the Transaction Entities shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay the Manager any commission to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver the Net Proceeds on any Settlement Date for the Shares delivered by the Company, the Manager will pay the Company interest based on the effective overnight federal funds rate on such unpaid amount.

(viii) At each Applicable Time, Settlement Date, Representation Date (as defined in Section 4(k)) and Filing Date (as defined in Section 4(aa), if any, the Transaction Entities shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, modified as necessary to relate to the Registration Statement and the Prospectus as amended as of such date. Any obligation of the Manager to use its reasonable efforts to sell the Shares on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Transaction Entities herein, to the performance by the Transaction Entities of their obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) Under no circumstances shall the number and aggregate gross price of the Shares sold pursuant to this Agreement and the Alternative Equity Distribution Agreements exceed any of (i) the aggregate amount set forth in Section 1, (ii) the number of shares of Common Stock available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Shares authorized from time to time to be issued and sold under this Agreement and the Alternative Equity Distribution Agreements by the Board, or a duly authorized committee thereof, and notified to the Manager in writing.

(c) If any of the parties to this Agreement has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Shares, it shall promptly notify the other parties and sales of the Shares under this Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(d) Notwithstanding any other provision of this Agreement the Company shall not request the sale of any Shares that would be sold, and the Manager shall not be obligated to sell, (i) during the 14 calendar days prior to the date (each, an “Announcement Date”) on which the Company shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (each, an “Earnings Announcement”), (ii) except as provided in Section 3(e) below, at any time from and including an Announcement Date through and including the time that is 24 hours after the time that the Company files (a “Filing Time”) a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement, or (iii) during any other period in which the Company is, or could be deemed to be, in possession of material non-public information,; provided that, unless otherwise agreed between the Company and the Managers, for purposes of (i) and (ii) above, such period shall be deemed to end 24 hours after the next subsequent Filing Time.

(e) If the Company wishes to offer, sell or deliver Shares at any time during the period from and including an Announcement Date through and including the time that is 24 hours after the corresponding Filing Time, the Company shall (i) prepare and deliver to the Manager (with a copy to counsel to the Manager) a Current Report on Form 8-K which shall include substantially the same financial and related information as was set forth in the relevant Earnings Announcement (other than any earnings projections, similar forward-looking data and officers’ quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to the Manager, and obtain the consent of the Manager to the filing thereof (such consent not to be unreasonably withheld), (ii) provide the Manager with the officers’ certificate, accountants’ letter and opinions and letters of counsel called for by Sections 4(k), 4(l), 4(m), 4(n), 4(o) and 4(p) hereof; respectively, (iii) afford the Manager the opportunity to conduct a due diligence review in accordance with Section 4(q) hereof and (iv) file such Earnings 8-K with the Commission, then the provisions of Section 3(d) shall not be applicable for the period from and after the time at which the foregoing conditions shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the time that is 24 hours after the Filing Time of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be. For purposes of clarity, the parties hereto agree that (A) the delivery of any officers’ certificate, accountants’ letter and opinions and letters of counsel pursuant to this Section 3(e) shall not relieve the Company from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including, without limitation, the obligation to deliver officers’ certificates, accountants’ letters and legal opinions and letters as provided in Section 4 hereof and (B) this Section 3(e) shall in no way affect or limit the operation of the provisions of Section 3(d), which shall have independent application.

4. Agreements. Each of the Transaction Entities, jointly and severally, agrees with the Manager that:

(a) During any period when delivery of a prospectus relating to the Shares is required (including in circumstances where such requirement may be satisfied pursuant to Rule 153 or 172 or similar rules) to be delivered under the Securities Act, the Transaction Entities will (i) not file any amendment to the Registration Statement or supplement to the Base Prospectus or Prospectus Supplement (other than (x) any amendment or supplement relating solely to the issuance or offering of securities other than the Shares and (y) any amendment or supplement by means of a Current Report on Form 8-K that is not a Financial 8-K (as defined in Section 4(k)) (each, a “Non-Financial 8-K”) filed with the Commission under the Exchange Act and incorporated or deemed to be incorporated by reference in the Registration Statement or the Prospectus), unless the Company has furnished to the Manager a copy for its review prior to filing and will not file any such proposed amendment or supplement to which the Manager reasonably objects and (ii) will give prior written notice to the Manager of the intention to file each Non-Financial 8-K and describe the subject matter to be included in each Non-Financial 8-K as soon as reasonably practicable prior to its filing. During any period when delivery of a prospectus relating to the Shares is not required (including in circumstances where such requirement may be satisfied pursuant to Rule 153 or 172 or similar rules) to be delivered under the Securities Act, the Transaction Entities will not file any amendment to the Registration Statement or supplement to the Base Prospectus or the Prospectus Supplement (other than (x) any amendment or supplement relating solely to the issuance or offering of securities other than the Shares and (y) any amendment or supplement by means of an Annual Report on Form 10-K, a Quarterly Report on Form 10-Q, a Proxy Statement on Schedule 14A or a Current Report on Form 8-K or any amendments thereto filed with the Commission under the Exchange Act and incorporated or deemed to be incorporated by reference in the Registration Statement or the Prospectus), unless the Company has furnished to the Manager a copy for its review prior to filing and will not file any such proposed amendment or supplement to which the Manager reasonably objects. The Transaction Entities have properly completed the Prospectus, in a form approved by the Manager, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Manager of such timely filing. The Company will promptly advise the Manager (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, during any period when the delivery of a prospectus (whether physically or through compliance with Rule 153 or 172 or any similar rules) is required under the Securities Act in connection with the offering or sale of the Shares , any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by either of the Transaction Entities of any notification with respect to the suspension of the qualification of the Shares for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. Each of the Transaction Entities will use its reasonable efforts to prevent the issuance

of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, during any period when the delivery of a prospectus relating to the Shares is required (including in circumstances where such requirement may be satisfied pursuant to Rule 153 or 172 or similar rules) to be delivered under the Securities Act, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made not misleading, the Transaction Entities will (i) notify promptly the Manager so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) subject to compliance with Section 4(a), amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Manager in such quantities as the Manager may reasonably request.

(c) During any period when the delivery of a prospectus relating to the Shares is required (including in circumstances where such requirement may be satisfied pursuant to Rule 153 or 172 or similar rules) to be delivered under the Securities Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Company promptly will (i) notify the Manager of any such event, (ii) prepare and file with the Commission, subject to compliance with Section 4(a), an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its reasonable efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Manager in such quantities as the Manager may reasonably request.

(f) The Company will arrange, if necessary, for the qualification of the Shares for sale under the laws of such jurisdictions as the Manager may designate and will maintain such qualifications in effect so long as required for the distribution of the Shares; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Shares, in any jurisdiction where it is not now so subject.

(g) Each of the Transaction Entities agrees that, unless it has or shall have obtained the prior written consent of the Manager, and the Manager agrees with the Transaction Entities that, unless it has or shall have obtained, as the case may be, the prior written consent of the Transaction Entities, it has not made and will not make any offer relating to the Shares that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed with the Commission or retained by the Transaction Entities under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses, if any, included in Schedule I hereto. Any such free writing prospectus consented to by the Manager or the Transaction Entities, as applicable, is hereinafter referred to as a “Permitted Free Writing Prospectus”. Each of the Transaction Entities 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 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

7. Indemnification and Contribution.

(a) The Transaction Entities jointly and severally agree to indemnify and hold harmless the Manager, the directors, officers, employees and agents of the Manager and each person who controls the Manager within the meaning of either the Securities Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Shares as originally filed or in any amendment thereof, or in the Base Prospectus, the Prospectus Supplement, any Interim Prospectus Supplement, the Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Transaction Entities will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by the Manager specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Transaction Entities may otherwise have.

(b) The Manager agrees to indemnify and hold harmless the Transaction Entities, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Transaction Entities within the meaning of either the Securities Act or the Exchange Act, to the same extent as the foregoing indemnity from the Transaction Entities to the Manager, but only with reference to written information relating to the Manager furnished to the Company by the Manager specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Manager may otherwise have. The Company and the Operating Partnership acknowledge that the only information furnished in writing by or on behalf of the Manager for inclusion in the Prospectus Supplement or the Prospectus is the information in the last two sentences of the first paragraph under the heading “Plan of Distribution” in the Prospectus Supplement, but only to the extent such information is with respect to the actions of the Manager and not any Alternative Manager.

(c) Promptly after receipt by an indemnified party under this Section 7 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent (A) includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and (B) does not include a statement as to, or an admission of, fault, culpability or a failure to act by or on behalf of an indemnified party.

(d) In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Transaction Entities and the Manager agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Transaction Entities and the Manager may be subject in such proportion as is appropriate to reflect the relative benefits received by the Transaction Entities on the one hand and by the Manager on the other from the offering of the Shares pursuant to this Agreement; provided, however, that in no case shall the Manager be responsible for any amount in excess of the underwriting discount or commission, as the case may be, applicable to the Shares sold by the Manager hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Transaction Entities and the Manager severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Transaction Entities on the one hand and of the Manager on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Transaction Entities shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Manager shall be deemed to be equal to the total underwriting discounts and commissions, in each case as determined by this Agreement. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Transaction Entities on the one hand or the Manager on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Transaction Entities and the Manager agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls the Manager within the meaning of either the Securities Act or the Exchange Act and each director, officer, employee and agent of the Manager shall have the same rights to contribution as the Manager, and each person who controls the Transaction Entities within the meaning of either the Securities Act or the Exchange Act, each officer of the Transaction Entities who shall have signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Transaction Entities, subject in each case to the applicable terms and conditions of this paragraph (d).

8. Termination.

(a) The Transaction Entities shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Shares in its sole discretion at any time.

respect to any pending sale, through the Manager for the Company, the obligations of the Transaction Entities, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 2, 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

(c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Sections 2, 5, 7 and 9 shall remain in full force and effect.

(d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Transaction Entities, as the case may be. If such termination shall occur prior to the Settlement Date for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

9. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of each of the Transaction Entities or its officers and of the Manager set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by the Manager or the Transaction Entities or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Shares.

Therefore, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained in, or incorporated by reference in, the Registration Statement, the Base Prospectus, the Prospectus Supplement or the Prospectus (or the Incorporated Documents) (except to the extent expressly set forth in the numbered paragraph 4 of our letter to you of even date and in our letter to you of even date with respect to certain tax matters), and have not made an independent check or verification thereof (except as aforesaid). However, in the course of acting as special counsel to the Company in connection with the preparation by the Company of the Registration Statement, the Base Prospectus, the Prospectus Supplement and the Prospectus, we reviewed the Registration Statement, the Base Prospectus, the Prospectus Supplement and the Prospectus, and the Incorporated Documents, and participated in conferences and telephone conversations with officers and other representatives of the Company, the independent public accountants for the Company, your representatives and your counsel, during which conferences and conversations the contents of the Registration Statement, the Prospectus Supplement and the Prospectus (and portions of certain of the Incorporated Documents) and related matters were discussed. We also reviewed and relied upon certain corporate records and documents, letters from counsel and accountants, and oral and written statements of officers and other representatives of the Company and others as to the existence and consequence of certain factual and other matters.

Based on our participation, review and reliance as described above, we advise you that no facts came to our attention that caused us to believe that:

•

the Registration Statement, as of the date of the Prospectus Supplement, including the information deemed to be a part of the Registration Statement pursuant to Rule 430B under the Act (together with the Incorporated Documents at that time), contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading;

•

[the Prospectus, as of the date hereof (together with Incorporated Documents at that date and the specified Issuer Free Writing Prospectuses), contained an untrue statement of a material fact or omitted to state a material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading; or]¹
