Certain terms used herein are defined in Section 18 hereof.

Each of the Transaction Entities, jointly and severally, represents and warrants to, and agrees with, the Manager at the Execution Time and on each such time the following representations and warranties are repeated or deemed to be made pursuant to this Agreement, as set forth below.

     (a) The Company and the Operating Partnership each meet the requirements for use of Form S-3 under the Act and prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405 (File Number 333-150737),

on Form S-3, including a related Base Prospectus, for registration under the Act of the offering and sale of certain securities, including the Shares.

The Company has filed with the Commission the Prospectus Supplement relating to the Shares in accordance with Rule 424(b). As filed, the Prospectus contains all information required by the Act and the rules thereunder, and, except to the extent the Manager shall agree in writing to a modification, shall be in all substantive respects in the form furnished to the Manager prior to the Execution Time or prior to any such time this representation is repeated or deemed to be made, and no order preventing or suspending the use of the Prospectus or any Issuer Free Writing Prospectus has been issued by the Commission.

          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 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 Shares sold by the Manager under this Section 3(a) on the NYSE at the time of sale of such Shares.

     (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, except as otherwise specifically agreed by the Manager and the Transaction Entities.

     (iii) The Company shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Share at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Trustees (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), suspend the offering of the Shares for any reason and at any time; provided, however, that such suspension or termination 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 (A) 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”) and (B) such other sales of the Shares on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Transaction Entities and the Manager pursuant to a Terms Agreement.

     (v) The compensation to the Manager for sales of the Shares with respect to which the Manager acts as sales agent under this Agreement shall be 2% of the gross sales price of the Shares sold pursuant to this Section 3(a). The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Company may sell Shares to the Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a

Terms Agreement. The remaining proceeds shall constitute the net proceeds to the Transaction Entities for such Shares (the “Net Proceeds”).

     (vi) The Manager shall provide written confirmation (which may be by facsimile or electronic mail) 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 payments in same day funds delivered to the account designated by the Transaction Entities. 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.

     (viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), 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) If the Company wishes to issue and sell the Shares pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Company wishes to accept

amended terms, the Manager and the Transaction Entities will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Transaction Entities or the Manager unless and until each of the Transaction Entities and the Manager have executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

     (c) Each sale of the Shares to the Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Shares to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Shares by the Manager. The commitment of the Manager to purchase the Shares pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Transaction Entities herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Shares to be purchased by the Manager pursuant thereto, the price to be paid to the Company for such Shares, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Shares, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Shares. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

     (d) Under no circumstances shall the number and aggregate amount of the Shares sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1 or (ii) the number and aggregate amount of the Shares authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Manager in writing.

     (e) If any of the parties 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 and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

     (f) Notwithstanding any other provision of this Agreement, the Transaction Entities agree that no sales of Shares shall take place, and the Transaction Entities shall not request the sale of any Shares, and the Manager shall not be obligated to sell, during any period in which either of the Transaction Entities is, or could be deemed to be, in possession of material non-public information; provided that, notwithstanding the provisions of this paragraph (f), the Transaction Entities agree that no sales of Shares shall take place during the fourteen (14) calendar days prior to an Earnings Release (as defined below).

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

     (a) 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 172) to be delivered under the Act, the Transaction Entities will not file any amendment of the Registration Statement or supplement (including the Prospectus Supplement) to the Base 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, in a form approved by the Manager, 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 Transaction Entities 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 172 or any similar rule) is required under the 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 any Rule 462(b) 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 best 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 best efforts to have such amendment or new registration statement declared effective as soon as practicable.

     (b) If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, 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 or the circumstances then prevailing 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) 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 172) to be delivered under the 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 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 the second sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best 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.

     (d) (i) As soon as practicable, the Company will make generally available to its security holders and to the Manager an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

     (ii) If either of the Transaction Entities makes any public announcement or release disclosing the Transaction Entities’ results of operations or financial condition for a completed quarterly or annual fiscal period (each, an “Earnings Release”) and the Transaction Entities have not yet filed a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K with respect to such information, as applicable, then, prior to any sale of Shares, the Transaction Entities shall be obligated to (x) file a prospectus supplement with the Commission under the applicable paragraph of Rule 424(b), which prospectus supplement shall include the applicable financial information, (y) file a Current Report on Form 8-K, which Form 8-K shall include the applicable financial information or (z) furnish a Current Report on Form 8-K pursuant to Item 2.02 thereof, which current report shall specifically state that the applicable financial information shall be deemed “filed” under the Exchange Act.

The Transaction Entities

jointly and severally agree to pay the expenses of printing or other production of all documents relating to the offering.

     (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.

     (h) The Company will not offer, sell, contract to sell, pledge, or otherwise dispose of, (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition of (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Company or any affiliate of the Company or any person in privity with the Company or any affiliate of the Company) directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other Common Shares or any securities convertible into, or exercisable, or exchangeable for, Common Shares; or publicly announce an intention to effect any such transaction without (i) giving the Manager at least five Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction and (ii) the Manager suspending acting under this Agreement for such period of time requested by the Company or as deemed appropriate by the Manager in light of the proposed transaction; provided, however, that the foregoing restrictions shall not prohibit (A) the Company from issuing Common Shares pursuant to (x) the Company’s Dividend Reinvestment and Share Purchase Plan as in effect at the Execution Time, (y) any of the Company’s employee or trustee benefit plans, including upon exercise of share options granted

pursuant thereto, as such plans are in effect at the Execution Time or (z) the exercise of contractual rights existing on the date of this Agreement by current and former holders of partnership or other interests in the Operating Partnership which may require or permit (in lieu of a payment in cash) the issuance of Common Shares by the Company, or the filing by the Company under the Act of a registration statement registering the resale of Common Shares upon conversion of Units (provided, however, that the Company shall notify the Manager prior to filing any such registration statement), or (B) the Operating Partnership from issuing any Units as consideration for the acquisition of real property.

     (i) The Transaction Entities will not (i) take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Shares or (ii) sell, bid for, purchase or pay any person (other than as contemplated by this Agreement or any Terms Agreement) any compensation for soliciting purchases of the Shares.

     (i) The Company shall have paid the required Commission filing fees relating to the Shares within the time period required by Rule 456(b)(1)(i) of the Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Act and, if applicable, shall have updated the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b).

     (n) Prior to each Settlement Date and Time of Delivery, as applicable, the Transaction Entities shall have furnished to the Manager such further information, certificates and documents as the Manager may reasonably request.

          7. Indemnification and Contribution.

     (a) The Transaction Entities 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 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 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, 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 or trustees, each of its officers who signs the Registration Statement, and each person who controls the Transaction Entities within the meaning of either the 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.

     (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 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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

     (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; 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 purchased 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 or any applicable Terms 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 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 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 Act or the Exchange Act, each officer of the Transaction Entities who shall have signed the Registration Statement and each trustee 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. Any such termination shall be without liability of any party to any other party except that (i) if Shares have been sold through the Manager for the Company, then Section 4(s) shall remain in full force and effect, (ii) with 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 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

          (b) The Manager 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.

          (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 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 or Time of Delivery for any sale of the Shares, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

          (e) In the case of any purchase of Shares by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Company prior to the Time of Delivery relating to such Shares, if at any time prior to such delivery and payment (i) trading in the Company’s Common Shares shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE or the American Stock Exchange or in the over-the-counter market shall have been suspended or limited or minimum prices shall have been established on such exchange or such market, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the United States or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or (iv) there shall have occurred any other calamity or crisis in the United States or elsewhere the effect of which on financial markets is such as to make it, in the sole judgment of the Manager, impractical or inadvisable to proceed with the offering or delivery of the Shares as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

          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. The provisions of Sections 5 and 7 hereof shall survive the termination or cancellation of this Agreement.

          12. No Fiduciary Duty. Each of the Transaction Entities hereby acknowledges and agrees that (a) the purchase and sale of the Shares pursuant to this Agreement is an arm’s-length commercial transaction between the Transaction Entities, on the one hand, and the Manager and any affiliate through which it may be acting, on the other, (b) the Manager is acting solely as sales agent and/or principal in connection with the purchase and sale of the Company’s securities and not as a fiduciary of the Transaction Entities and (c) the Transaction Entities’ engagement of the Manager in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, each of the Transaction Entities agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Manager has advised or is currently advising the Transaction Entities on related or other matters). Each of the Transaction Entities agrees that it will not claim that the Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Transaction Entities, in connection with such transaction or the process leading thereto.
