3. Agreement to Sell and Purchase. The REIT hereby agrees to issue and sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained and upon the terms and subject to the conditions herein set forth, agrees, severally and not jointly, to purchase from the REIT, the respective number of Firm Shares set forth in Schedule I hereto opposite its name. The purchase price per share of the Shares to be paid by the several Underwriters to the REIT shall be $26.40 a share (the “Purchase Price”).

In addition, the REIT hereby agrees to issue and sell to the several Underwriters, and the Underwriters, upon the basis of the representations and warranties herein contained and upon the terms and subject to the conditions herein set forth, shall have the right to purchase, at any time or from time to time, but no more than twice, severally and not jointly, from the REIT any or all of the Additional Shares at the Purchase Price. If you, on behalf of the Underwriters, elect to exercise such option, you shall so notify the REIT in writing not later than 30 days after the date of this Agreement, which notice shall specify the number of Additional Shares to be purchased by the Underwriters and the date on which such shares are to be purchased. Such date may be the same as the Closing Date (as defined below), but not earlier than the Closing Date nor later than ten (10) business days after the date of such notice. Additional Shares may be purchased as provided in Section 5 hereof solely for the purpose of covering over-allotments made in

connection with the offering of the Firm Shares. If any Additional Shares are to be purchased, each Underwriter agrees, severally and not jointly, to purchase the number of Additional Shares (subject to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the total number of Additional Shares to be purchased as the number of Firm Shares set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

Each of the REIT and the Operating Partnership hereby agrees that, without the prior written consent of each of Morgan Stanley & Co. Incorporated, J.P. Morgan Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated on behalf of the Underwriters, it will not, directly or indirectly, during the period commencing on the date hereof and ending 90 days after the date of the Prospectus, (i) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of any shares of its Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock or any other securities substantially similar to the Common Stock or (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of Common Stock, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of shares of Common Stock, other securities, in cash or otherwise. The restrictions described in the foregoing sentence shall not apply to (1) the Shares to be sold hereunder, (2) the issuance by the Company of options, restricted stock units or shares of restricted Common Stock pursuant to the Company’s existing employee stock option plans in the ordinary course and consistent with past practice and the Company’s standard vesting schedule, (3) the issuance of any shares of Common Stock upon the exercise of options or restricted stock units granted under existing employee stock option plans in the ordinary course and consistent with past practice and the Company’s standard vesting schedule, (4) the issuance by the Company of up to 5% of the total number of shares of Common Stock outstanding immediately after the completion of this offering (assuming the exchange for shares of Common Stock of all Units and AMB Property II, L.P. units outstanding immediately after the completion of this offering) in connection with acquisitions of properties, portfolios of properties or interests in property-owning or real estate-related entities; provided that the recipients of such shares agree to be bound by the restrictions described in this paragraph, (5) the issuance of Units or AMB Property II, L.P. units in connection with the acquisition of properties by the Company, (6) the issuance of shares of Common Stock in exchange for Units or AMB Property II, L.P. units, (7) the issuance by the Company of shares of Common Stock, not to exceed an aggregate value of $140,000, as anniversary grants to certain Company employees, (8) gifts by the Company of shares of Common Stock, not to exceed an aggregate value of $10,000, to property brokers, which shares will be purchased by the Company on the open market, or (9) the redemption or repurchase by the Company of any of its securities, including, without limitation, Units or limited partnership units of AMB Property II, L.P. Notwithstanding the foregoing, if (1) during the last 17 days of the 90-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 90-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 90-day period, the restrictions imposed by this Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the occurrence of the material news or material event.

4. Terms of Public Offering. The REIT is advised by you that the Underwriters propose to make a public offering of their respective portions of the Shares as soon after this Agreement has become effective as in your judgment is advisable. The REIT is further advised by you that the Shares are to be offered to the public initially at $27.50 a share (the “Public Offering Price”), and to certain dealers selected by you at a price that represents a concession not in excess of $0.66 a share under the Public Offering Price.

5. Payment and Delivery. Payment of the aggregate Purchase Price for the Firm Shares shall be made to the REIT in federal or other funds immediately available in New York City against delivery of such Firm Shares to the Representatives for the respective accounts of the several Underwriters at 10:00 A.M., New York City time, on the third full business day following the date of this Agreement, or at such other time on the same or such other date as shall be agreed to in writing by the REIT and the Representatives. The time and date of such payment are hereinafter referred to as the “Closing Date.”

7. Covenants of the REIT and the Operating Partnership. In further consideration of the agreements of the Underwriters herein contained, the REIT and the Operating Partnership covenant with each Underwriter as follows:

(a) The Company will advise the Representatives promptly of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or an order preventing or suspending the use of the Preliminary Prospectus Supplement, the Prospectus Supplement, the Prospectus or any Issuer Represented Free Writing Prospectus or of the institution or threatening of any proceedings for that purpose or pursuant to Section 8A of the Securities Act, and will use their best efforts to prevent the issuance of any such order and to obtain as soon as possible the lifting thereof, if issued, and will advise the Representatives promptly of any examination pursuant to 8(e) of the Securities Act or of the REIT or Operating Partnership becoming the subject of a proceeding pursuant to 8A of the Securities Act in connection with any offering of the Shares. The Company will advise the Representatives promptly of the receipt by the Company of any notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act. The REIT and the Operating Partnership will advise the Representatives promptly of any request by the Commission for any amendment of or supplement to the Registration Statement or the Prospectus or any Issuer Represented Free Writing Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or the Prospectus or any Issuer Represented Free Writing Prospectus or any other request by the Commission for additional information. Prior to the termination of the offering of the Shares and at any time during which the Underwriters have a prospectus delivery requirement under the Commission’s rules and regulations, the Company will not at any time file any amendment to the Registration Statement or supplement to the Prospectus or any Issuer Represented Free Writing Prospectus which shall not previously have been submitted to the Representatives a reasonable time prior to the proposed filing or use thereof or to which the Representatives shall reasonably object or which is not in compliance with the Securities Act and the rules and regulations thereunder. The REIT and the Operating Partnership will cause the Preliminary Prospectus Supplement, the Prospectus Supplement and any Issuer Represented Free Writing Prospectus to be filed within the required time periods, and will advise you promptly when the Prospectus has been filed pursuant to Rule 424(b) and

Rule 430A, 430B or 430C under the Securities Act and any Issuer Represented Free Writing Prospectus has been filed pursuant to Rule 433 under the Securities Act, and will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Shares. The Company will pay the registration fees for this offering within the time period required by Rule 456(b)(i) under the Securities Act prior to the Closing Date.

(b) To furnish to you, upon request and without charge, a signed copy of the Registration Statement as originally filed and each amendment thereto (including exhibits and consents filed therewith) and for delivery to each other Underwriter a conformed copy of the Registration Statement as originally filed and each amendment thereto (without exhibits thereto) and to furnish to you in New York City, without charge, prior to 10:00 A.M. New York City time on the business day next succeeding the date of this Agreement and during the period mentioned in Section 7(c) below, as many copies of the General Disclosure Package and Prospectus and any supplements and amendments thereto or to the Registration Statement as you may reasonably request. The Company will, pursuant to reasonable procedures developed in good faith, retain copies of each Issuer Represented Free Writing Prospectus that is not filed with the Commission in accordance with Rule 433 under the Securities Act.

(c) If, at any time prior to the Closing Date or during such period after the first date of the public offering of the Shares, in the opinion of counsel for the Underwriters, the Prospectus or the General Disclosure Package is required by law to be delivered in connection with sales of Shares by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the General Disclosure Package or the Prospectus in order to ensure that the General Disclosure Package or the Prospectus do not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading when the General Disclosure Package or the Prospectus is delivered to a purchaser, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus or the General Disclosure Package to comply with applicable law, the Company will immediately notify the Underwriters and forthwith prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses you will furnish to the REIT and the Operating Partnership) to which Shares may have been sold by you on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus and/or the General Disclosure Package so that the statements in the Prospectus and the General Disclosure Package as so amended or supplemented will not contain an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading when the Prospectus or the General Disclosure Package is delivered to a purchaser, or so that the Prospectus and the General Disclosure Package, as amended or supplemented, will comply with law.

(d) To endeavor to qualify the Shares for offer and sale under the securities or Blue Sky laws and real estate syndication laws of such jurisdictions as you shall reasonably request. The Company will advise the Representatives promptly of the receipt by the Company of any notice with respect to any suspension of the qualification of the Shares for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its best efforts to prevent the issuance of any such order suspending any such qualification of the Shares and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(e) To make generally available to the REIT’s security holders and to you as soon as practicable (but no event later than the last day of the fifteenth full calendar month following the end of the REIT’s current fiscal quarter), an earnings statement covering the twelve-month period beginning after the date upon which the Prospectus Supplement is filed pursuant to Rule 424 under the Securities Act that satisfies the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(f) Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, to pay or cause to be paid all expenses incident to the performance of its obligations under this Agreement, including: (i) the fees, disbursements and expenses of counsel for the Company and the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, the Preliminary Prospectus Supplement, the Prospectus Supplement, the Prospectus and any Issuer Represented Free Writing Prospectus, and any amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the cost of printing or producing any Blue Sky or Legal Investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 7(d) hereof, including filing fees and the reasonable fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or Legal Investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Shares by the Financial Industry Regulatory Authority, Inc., if any, (v) all costs and expenses incident to listing the Shares on the NYSE, (vi) the cost of printing certificates representing the Shares, if applicable, (vii) the fees and expenses of any transfer agent, registrar or depositary in connection with the issuance of the Shares, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior approval of the REIT, travel and lodging expenses of the representatives and officers of the REIT and any such consultants, and, with the

prior approval of the REIT, the cost of any aircraft chartered in connection with the road show and (ix) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section. It is understood, however, that except as provided in this Section, Section 8 entitled “Indemnity and Contribution” and the last paragraph of Section 10 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make.

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

(h) The Company shall have applied to list the Shares, and the Shares shall have been approved for listing, subject to notice of issuance, on the NYSE on or prior to the Closing Date, and the REIT and the Operating Partnership shall use its best efforts to maintain the listing of such Shares on the NYSE.

(i) Except for the authorization of actions permitted to be taken by the Underwriters as contemplated herein or in the Prospectus or the General Disclosure Package, neither the REIT nor the Operating Partnership will, within 30 days of the date of the Prospectus, directly or indirectly, (i) take 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 REIT or the Operating Partnership to facilitate the sale or resale of the Shares, (ii) sell, bid for or purchase the Shares or pay any person any compensation for soliciting purchases of the Shares or (iii) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the REIT or the Operating Partnership, which payment or agreement is designed to cause or to result in the stabilization or manipulation of the price of the Shares.

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

8. Indemnity and Contribution.

(a) The REIT and the Operating Partnership, jointly and severally, agree to indemnify and hold harmless each Underwriter and their respective affiliates and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) arising out of or caused by (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, the Preliminary Prospectus Supplement, Prospectus Supplement, the Prospectus, the Information 8-Ks, the Road Show or any Issuer Represented Free Writing Prospectus (in each case, as amended or supplemented if the REIT and the Operating Partnership shall have furnished any amendments or supplements thereto) or in any documents filed under the Securities Act or the Exchange Act and incorporated by reference or deemed to be incorporated by reference into the Registration Statement, the Preliminary Prospectus Supplement, Prospectus Supplement, the Prospectus or the General Disclosure Package or in any application or other document executed by or on behalf of the Company or based on written information furnished by or on behalf of the Company filed in any jurisdiction in order to qualify the Shares under the securities or Blue Sky laws thereof or filed with the Commission, (ii) any omission or alleged omission to state in the Registration Statement, the Prospectus, or the General Disclosure Package, the Information 8-Ks, the Road Show or any Issuer Represented Free Writing Prospectus a material fact required to be stated therein or necessary to make the statements therein not misleading, or (iii) any act or failure to act or any alleged act or failure to act by any Underwriter in connection with, or relating in any manner to, the Shares or the offering contemplated hereby, and which is included as part of or referred to in any loss, claim, damage, liability or expense arising out of or based upon matters covered by clause (i) or (ii) above (provided, however, that the REIT and the Operating Partnership shall not be liable under this clause (iii) to the extent it is finally judicially determined by a court of competent jurisdiction that such loss, claim, damage, liability or expense resulted directly from any such acts or failures to act undertaken or omitted to be taken by such Underwriter through its gross negligence or willful misconduct), except insofar as such losses, claims, damage, liabilities or expenses are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the REIT and the Operating Partnership in writing by such Underwriter through you expressly for use in the Registration Statement, the Permitted Free Writing Prospectus or the Prospectus, which information is limited to that set forth on Exhibit A hereof. This indemnity agreement will be in addition to any liability that the REIT or the Operating Partnership might otherwise have.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the REIT, the Operating Partnership and the REIT’s directors, its officers who sign the Registration Statement and each person, if any, who controls the REIT or the Operating Partnership within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnities from the REIT and the Operating Partnership to such Underwriter, but only with reference to information relating to such Underwriter furnished to the REIT in writing by such Underwriter through you expressly for use in the Registration Statement, the Permitted Free Writing Prospectus or the Prospectus, which information is limited to that set forth on Exhibit A hereto.

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 8(a) or 8(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party (who shall not, without the consent of the indemnified party, be counsel to the indemnifying party) to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding, provided that the failure to notify the indemnifying party shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under paragraph (a) or (b) above. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all such indemnified parties and that all such fees and expenses shall be reimbursed as they are incurred. Such firm shall be designated in writing by the Representatives, in the case of parties indemnified pursuant to Section 8(a), and by the REIT or the Operating Partnership, in the case of parties indemnified pursuant to Section 8(b). The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party in writing to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 60 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of each indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (x) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any indemnified person.

(d) To the extent the indemnification provided for in Section 8(a) or 8(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or

liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the REIT and the Operating Partnership on the one hand and the Underwriters on the other hand from the offering of the Shares or (ii) if the allocation provided by clause (i) above 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 REIT and the Operating Partnership on the one hand and of the Underwriters on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the REIT and the Operating Partnership on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the REIT and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the REIT and the Operating Partnership on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the REIT or the Operating Partnership or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 8 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) The REIT, the Operating Partnership and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 8 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 8(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 8 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 8 and the representations, warranties and other statements of the REIT and the Operating Partnership contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any

Underwriter or any person controlling any Underwriter or by or on behalf of the REIT, the Operating Partnership or the REIT’s officers or directors or any person controlling the REIT or the Operating Partnership and (iii) acceptance of and payment for any of the Shares.

9. Termination. The obligations of the Underwriters under this Agreement may be terminated at any time on or prior to the Closing Date, by notice to the REIT and the Operating Partnership from the Underwriters, without liability on the part of the Underwriters to the REIT and the Operating Partnership, if, prior to delivery and payment for the Shares, in the sole judgment of the Underwriters, (i) trading in any of the securities of the REIT or the Operating Partnership shall have been suspended by the Commission, by any exchange that lists such securities or in any over-the-counter market, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum or maximum prices shall have been generally established on such exchange, or additional material governmental restrictions, not in force on the date of this Agreement, shall have been imposed upon trading in securities generally by such exchange or by order of the Commission or any court or other governmental authority, (iii) a general banking moratorium shall have been declared by either Federal or New York State authorities or (iv) any material adverse change in the financial or securities markets within or outside the United States or in political, financial or economic conditions within or outside the United States or any material outbreak or material escalation of hostilities within or outside the United States or declaration by the United States of a national emergency or war or other material calamity or crisis within or outside the United States, including, without limitation, an act of terrorism, shall have occurred the effect of any of which is such as to make it, in the judgment of the Underwriters, impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the terms and in the manner contemplated by the Prospectus, the General Disclosure Package and this Agreement.

10. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto. If, on the Closing Date or the Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as you may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 10 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased and arrangements satisfactory to the Representatives and the REIT for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the REIT. In any such case, either the Representatives or the REIT shall have the right to postpone the Closing Date, but in no event for longer than

seven (7) days, in order that the required changes, if any, in the Registration Statement, the Prospectus and the General Disclosure Package or in any other documents or arrangements may be effected. If, on the Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase Additional Shares or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the REIT or the Operating Partnership to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the REIT or the Operating Partnership shall be unable to perform their obligations under this Agreement, the REIT and the Operating Partnership will, jointly and severally, reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

11. Representations and Agreements to Survive Delivery. All representations, warranties, agreements and covenants of the REIT and the Operating Partnership herein or in certificates delivered pursuant hereto and the agreements of the Underwriters in Section 8 herein shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling persons, or the REIT or the Operating Partnership or any of its officers, trustees, or any controlling persons, and shall survive (i) termination of this Agreement and (ii) delivery of and payment for the Shares hereunder.
