Ladies and Gentlemen:

     Vornado Realty Trust, a Maryland real estate investment trust (the “Company”), confirms its agreement with you (the “Underwriter,” which term shall also include any underwriter substituted as hereinafter provided in Section 10 hereof), with respect to the issue and sale by the Company and the purchase by you of the number of Common Shares of Beneficial Interest, par value $0.04 per share, of the Company (“Common Shares”) set forth above, and with respect to the grant by the Company to you of the option described in Section 2(b) hereof to purchase all or any part of 1,350,000 additional Common Shares to cover over-allotments, if any. The aforesaid 9,000,000 Common Shares (the “Initial Securities”) to be purchased by you and all or any part of the 1,350,000 Common Shares subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called, collectively, the “Securities.”

     The Company understands that you propose to offer the Securities (the “Offering”) as set forth in the prospectus supplement as soon after the execution and delivery hereof as in your judgment is advisable.

     The Company has filed with the Securities and Exchange Commission (the “Commission”) one or more registration statements on Form S-3, including a prospectus relating to the Common Shares and other securities of the Company for the registration of such securities under the Securities Act of 1933, as amended (the “1933 Act”). Such registration statements have been declared effective by the Commission. A prospectus supplement reflecting the terms of the Securities, the terms of the offering thereof and the other matters set forth therein has been prepared or will be prepared and will be filed in accordance with the provisions of paragraph (b) of Rule 424 (“Rule 424(b)”) of the rules and regulations of the Commission under the 1933 Act (the “1933 Act Regulations”). Such prospectus supplement, in the form first filed after the date hereof pursuant to Rule 424(b), is hereinafter called the “Prospectus Supplement.” Such registration statements, as amended at the date hereof, including all documents incorporated or deemed to be incorporated by reference therein and the exhibits thereto, and schedules thereto, if any, are hereinafter called the “Registration Statement” and the basic prospectus included therein and relating to all offerings of securities under the Registration Statement, as supplemented by the Prospectus Supplement, is hereinafter called the “Prospectus,” except that if such basic prospectus is amended or supplemented on or prior to the date on which the Prospectus

Supplement is first filed pursuant to Rule 424(b), the term “Prospectus” shall refer to the basic prospectus as so amended or supplemented and as supplemented by the Prospectus Supplement, including the documents filed by the Company with the Commission pursuant to the Securities Exchange Act of 1934, as amended (the “1934 Act”), that are incorporated by reference therein. For purposes of this Agreement, all references to the Registration Statement or the Prospectus or any amendment or supplement to either of the foregoing shall be deemed to include the copy filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

     All references in this Agreement to financial statements and schedules and other information which is “contained,” “included,” “stated,” “described,” “discussed” or “set forth” in the Registration Statement or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information which is incorporated by reference in the Registration Statement or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, or the Prospectus shall be deemed to mean and include the filing of any document under the 1934 Act which is incorporated by reference in the Registration Statement or the Prospectus, as the case may be.

     SECTION 1. Representations and Warranties.

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

     (i) Incorporated Documents. The documents incorporated by reference in the Registration Statement and the Prospectus, when they became effective or were filed with the Commission, as the case may be, conformed in all material respects to the requirements of the 1933 Act or the 1934 Act, as applicable, and the rules and regulations of the Commission thereunder, and none of such documents 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 in light of the circumstances under which they were made; and any further documents so filed and incorporated by reference in the Registration Statement and the Prospectus or any further amendment or supplement thereto, when such documents become effective or are filed with the Commission, as the case may be, will conform in all material respects to the requirements of the 1933 Act or the 1934 Act, as applicable, and the rules and regulations of the Commission thereunder and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter expressly for use in the Registration Statement or the Prospectus, in each case as amended or supplemented, relating to such Common Shares;

     (ii) Compliance with Registration Requirements. The Registration Statement and the Prospectus conform, and any further amendments or supplements to the Registration Statement or the Prospectus will conform, in all material respects to the requirements of the 1933 Act and the 1933 Act Regulations and do not and will not, as of the applicable effective date as to the Registration Statement and any amendment thereto and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances under which they were made; provided, however, that this representation and warranty shall not apply to any statements or omissions made in reliance upon and in conformity with information furnished in writing to the Company by the Underwriter expressly for use in the Prospectus as amended or supplemented relating to such Common Shares;

     (iii) Form S-3 Eligibility. The Company meets the requirements for use of Form S-3 under the 1933 Act and has filed with the Commission one or more registration statements on Form S-3, including a prospectus relating to the Common Shares and other securities of the Company for the registration of such securities under the 1933 Act and such registration statements have been declared effective by the Commission;

     (iv) No Material Adverse Change in Business. Neither the Company nor any of its subsidiaries has sustained since the date of the latest audited financial statements included or incorporated by reference in the Prospectus any material loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus; and, since the respective dates as of which information is given in the Registration Statement and the Prospectus, except as otherwise stated therein, there has not been any change in the capitalization or long-term debt of the Company or any material adverse change in or affecting the condition, financial or otherwise, or the earnings or business affairs (a “Material Adverse Effect”) of the Company and its subsidiaries taken as a whole, otherwise than as set forth or contemplated in the Prospectus;

     (v) Good Standing of the Company. The Company is a real estate investment trust duly formed and existing under the laws of the State of Maryland in good standing with the State Department of Assessments and Taxation of Maryland (“SDAT”), with trust power to own, lease and operate its properties and to conduct its business substantially as described in the Prospectus and to enter into and perform its obligations under this Agreement; and the Company is duly qualified as a foreign organization to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify would not have a Material Adverse Effect on the Company and its subsidiaries taken as a whole;

     (vi) Qualification as a REIT. The Company is organized and, commencing with its taxable year ended December 31, 1993, has operated in conformity with the requirements for qualification as a real estate investment trust (a “REIT”) under the

Internal Revenue Code of 1986, as amended (the “Code”), and currently intends to operate in a manner which allows the Company to continue to meet the requirements for taxation as a REIT under the Code;

     (vii) Good Standing of the Operating Partnership. Vornado Realty L.P. (the “Operating Partnership”) has been duly formed and is validly existing as a limited partnership in good standing under the laws of the State of Delaware and has partnership power and authority to own, lease and operate its properties and to conduct its business substantially as described in the Prospectus and is duly qualified as a foreign organization to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify would not have a Material Adverse Effect on the Operating Partnership; all of the issued and outstanding limited partnership interests in the Operating Partnership have been duly authorized and validly issued and are fully paid and (except for the general partner interest) nonassessable; the Company is the sole general partner of, and owned an approximately 88.4% common limited partnership interest in, the Operating Partnership as of June 30, 2005;

     (viii) Good Standing of Subsidiaries. Each subsidiary of the Company, other than the Operating Partnership, which is covered in paragraph (vii) above, has been duly formed and is validly existing in good standing under the laws of the jurisdiction of its organization and has power and authority to own, lease and operate its properties and to conduct its business substantially as described in the Prospectus and is duly qualified as a foreign organization to transact business and is in good standing in each jurisdiction in which such qualification is required, whether by reason of the ownership or leasing of property or the conduct of business, except where the failure to so qualify would not have a Material Adverse Effect on the Company and its subsidiaries taken as a whole; all of the issued and outstanding capital stock of each such subsidiary has been duly authorized and validly issued, is fully paid and nonassessable and is owned by the Company or the Operating Partnership, directly or through subsidiaries, free and clear of any security interest, mortgage, pledge, lien, encumbrance, claim or equity, except as would not have a Material Adverse Effect on the Company and its subsidiaries taken as a whole and except as disclosed in the Prospectus;

     (ix) Capitalization. The Company has an authorized capitalization as set forth in its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2005 (except for (a) subsequent issuances, if any, pursuant to this Agreement or pursuant to the terms of reservations, agreements or employee benefit plans, including, without limitation, dividend reinvestment plans and employee or director stock option plans or as otherwise described in the Prospectus or the exercise of options outstanding on the date hereof and (b) subsequent amendments to its Declaration of Trust);

     (x) Authorization and Description of the Common Shares. The Common Shares have been duly authorized, and, when the Initial Securities are issued and delivered pursuant to this Agreement and, in the case of any Option Securities, pursuant to over-allotment options with respect to such Common Shares, such Securities will be duly and validly issued and fully paid and nonassessable; the Common Shares conform to

the description thereof contained in the Prospectus under the caption “Description of Shares of Beneficial Interest of Vornado Realty Trust”;

     (xi) Absence of Conflicts and Defaults. The issue and sale of the Common Shares and each over-allotment option, if any, and the compliance by the Company with all of the provisions of this Agreement and each over-allotment option, if any, and the consummation of the transactions contemplated herein have been duly authorized by all necessary trust action of the Company and, except as would not have a Material Adverse Effect on the Company and its subsidiaries taken as a whole, will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company or any of its subsidiaries is a party or by which the Company or any of its subsidiaries is bound or to which any of the property or assets of the Company or any of its subsidiaries is subject, nor will such action result in any violation of the provisions of the Amended and Restated Declaration of Trust, as amended, or Bylaws of the Company or (except as where such violation would not cause a Material Adverse Effect on the Company and its subsidiaries taken as a whole or any adverse effect on the Company’s ability to consummate the transactions contemplated hereby) any statute or any order, rule or regulation of any court or governmental authority, agency or body having jurisdiction over the Company or any of its properties; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue and sale of the Common Shares or the consummation by the Company of the transactions contemplated by this Agreement or any over-allotment option, except such as have been, or will have been prior to the Closing Time and each Date of Delivery (as defined in Section 2(b) hereof), obtained under the 1933 Act and the 1933 Act Regulations and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the purchase and distribution of the Common Shares by the Underwriter;

     (xii) Authorization of this Underwriting Agreement. This Agreement has been duly authorized by all necessary trust action of the Company and all necessary partnership action of the Operating Partnership and has been executed and delivered by the Company and the Operating Partnership;

     (xiii) Absence of Proceedings. Other than as set forth in the Prospectus, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject, which, if determined adversely to the Company or any of its subsidiaries, would individually or in the aggregate have a Material Adverse Effect on the Company and its subsidiaries taken as a whole; and, to the best of the Company’s knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others; and there are no contracts or documents of the Company or any of its subsidiaries which are required to be filed as exhibits to the Registration Statement by the 1933 Act or the 1933 Act Regulations which have not been so filed, except where the failure to file such exhibit would not amount to an untrue statement of a material fact or omission of a statement of a material fact required to make the statements in the

Registration Statement not misleading in light of the circumstances under which they were made;

     (xiv) No Violations or Defaults. Neither the Company nor any of its subsidiaries is in violation of its organizational documents or bylaws or in default in the performance or observance of any material obligation, agreement, covenant or condition contained in any material indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which it is a party or by which it or any of its properties or assets may be bound, which default would have a Material Adverse Effect on the Company and its subsidiaries taken as a whole;

     (xv) Accuracy of Certain Descriptions. The statements set forth in the Prospectus under the captions “Description of Shares of Beneficial Interest of Vornado Realty Trust,” “Federal Income Tax Considerations,” “Plan of Distribution” and “Underwriting,” insofar as they purport to describe the provisions of the laws and documents referred to therein, are accurate, complete and fair summaries in all material respects;

     (xvi) Investment Company Act. Neither the Company nor the Operating Partnership is subject to registration as an “investment company” under the Investment Company Act;

     (xvii) Independent Public Accountants. Deloitte & Touche LLP, who have certified certain financial statements and financial statement schedules of the Company and its subsidiaries included or incorporated by reference in the Registration Statement, are an independent public accounting firm with respect to the Company as required by the 1933 Act and the 1933 Act Regulations;

     (xviii) Financial Statements. The financial statements and the financial statement schedules of the Company and its consolidated subsidiaries included or incorporated by reference in the Registration Statement and the Prospectus present fairly, in all material respects, the financial position of the Company and its consolidated subsidiaries as at the dates indicated, the results of their operations for the periods specified and the information required to be stated therein; and said financial statements and financial statement schedules have been prepared in conformity with generally accepted accounting principles applied on a consistent basis throughout the periods involved. The selected financial data included or incorporated by reference in the Prospectus present fairly, in all material respects, the information shown therein and have been compiled on a basis consistent with that of the consolidated financial statements included or incorporated by reference in the Registration Statement. Any pro forma financial statements and other pro forma financial information included in the Registration Statement and the Prospectus comply in all material respects with the applicable requirements of Rule 11-02 of Regulation S-X of the Commission and present fairly the information shown therein; the pro forma adjustments, if any, have been properly applied to the historical amounts in the compilation of such statements, and in the opinion of the Company, the assumptions used in the preparation thereof are reasonable and the

adjustments used therein are appropriate to give effect to the transactions or circumstances referred to therein;

     (xix) Title to Property. Except as otherwise disclosed in the Prospectus, and except as would not have a Material Adverse Effect on the Company and its subsidiaries taken as a whole: (i) each of the Company and its subsidiaries has good and marketable title to all properties and assets described in the Prospectus as owned by such party; (ii) all of the leases under which the Company or any of its subsidiaries holds or uses real property or assets as a lessee are in full force and effect, and neither the Company nor any of its subsidiaries is in material default in respect of any of the terms or provisions of any of such leases and no claim has been asserted by anyone adverse to any such party’s rights as lessee under any of such leases, or affecting or questioning any such party’s right to the continued possession or use of the leased property or assets under any such leases; (iii) all liens, charges, encumbrances, claims, or restrictions on or affecting the properties and assets of the Company or any of its subsidiaries that are required to be disclosed in the Prospectus are disclosed therein; (iv) neither the Company, any of its subsidiaries nor, to the knowledge of the Company, any lessee of any portion of any such party’s properties is in default under any of the leases pursuant to which the Company or any of its subsidiaries leases its properties to third parties and neither the Company nor any of its subsidiaries knows of any event which, but for the passage of time or the giving of notice, or both, would constitute a default under any of such leases; (v) no tenant under any lease pursuant to which the Company or any of its subsidiaries leases its properties has an option or right of first refusal to purchase the premises leased thereunder; (vi) to the best of its knowledge, each of the properties of the Company or any of its subsidiaries complies with all applicable codes and zoning laws and regulations; and (vii) neither the Company nor any of its subsidiaries has knowledge of any pending or threatened condemnation, zoning change or other proceeding or action that will in any manner affect the size or use of, improvements or construction on or access to the properties of the Company or any of its subsidiaries;

     (xx) Environmental Laws. Except as otherwise disclosed in the Prospectus, or as is not reasonably likely to have a Material Adverse Effect on the Company and its subsidiaries taken as a whole:

     A. each of the Company and its subsidiaries is in compliance with all applicable laws relating to pollution or the discharge of materials into the environment, including common law standards of conduct relating to damage to property or injury to persons caused by such materials (“Environmental Laws”), each of the Company and its subsidiaries currently holds all governmental authorizations required under Environmental Laws in order to conduct their businesses as described in the Prospectus, and neither the Company nor any of its subsidiaries has any basis to expect that any such governmental authorization will be modified, suspended or revoked, or cannot be renewed in the ordinary course of business;

     B. there are no past or present actions, activities, circumstances, conditions, events or incidents, including, without limitation, the release,

threatened release, or disposal of any material (including radiation and noise), that could reasonably be expected to form the basis of any claim (whether by a governmental authority or other person or entity) under Environmental Laws for cleanup costs, damages, penalties, fines, or otherwise, against any of the Company or its subsidiaries, or against any person or entity whose liability for such claim may have been retained by any of the Company or its subsidiaries, whether by contract or law; and

     C. the Company and its subsidiaries have made available to the Underwriter or counsel for the Underwriter all material studies, reports, assessments, audits and other information in their possession or control relating to any pollution or release, threatened release or disposal of materials regulated under Environmental Laws on, at, under, from or transported from any of their currently or formerly owned, leased or operated properties, including, without limitation, all information relating to underground storage tanks and asbestos containing materials.

     (xxi) No Stabilizing Actions. Except as in compliance with Regulation M, neither the Company nor the Operating Partnership has taken, and neither the Company nor the Operating Partnership will take, directly or indirectly, any action designed to, or that might be reasonably expected to, cause or result in stabilization or manipulation of the price of the Common Shares.

     (xxii) No Fiduciary Duty.

           The Company hereby acknowledges that (a) the Underwriter is acting as principal and not as an agent or fiduciary of the Company and (b) the Company’s engagement of the Underwriter in connection with the Offering is as an independent contractor and not in any other capacity. Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the Offering (irrespective of whether the Underwriter has advised or is currently advising the Company on related or other matters).

     (b) Officers’ Certificates. Any certificate signed by any officer of the Company or any of its subsidiaries delivered to the Underwriter or counsel for the Underwriter shall be deemed a representation and warranty by the Company to the Underwriter as to the matters covered thereby.

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

     (a) Initial Securities. On the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company agrees to sell to the Underwriter, and the Underwriter agrees to purchase from the Company, at the price per share set forth in Schedule A, the aggregate principal amount of Initial Securities set forth in Schedule A.

     (b) Option Securities. In addition, on the basis of the representations and warranties herein contained and subject to the terms and conditions herein set forth, the Company hereby grants an option to the Underwriter to purchase up to an additional 1,350,000 Common Shares at the price per share set forth in Schedule A. The option hereby granted will expire 30 days after the date hereof and may be exercised in whole or in part from time to time only for the purpose of covering over-allotments which may be made in connection with the offering and distribution of the Initial Securities upon notice by the Underwriter to the Company setting forth the number of Option Securities as to which the Underwriter is then exercising the option and the time and date of payment and delivery for such Option Securities. Any such time and date of delivery for the Option Securities (a “Date of Delivery”) shall be determined by you, but shall not be later than seven full business days after the exercise of said option, nor in any event prior to the Closing Time, as hereinafter defined.

     (c) Payment. Payment of the purchase price for, and delivery through the facilities of The Depository Trust Company (“DTC”) of certificates for, the Securities shall be made at the offices of Skadden, Arps, Slate, Meagher & Flom LLP, Four Times Square, New York, New York 10036 or at such other place as shall be agreed upon by you and the Company, at 9:00 a.m. (Eastern time) on the third (fourth, if the pricing occurs after 4:30 p.m. (Eastern time) on any given day) business day after the date hereof, or such other time not later than ten business days after such date as shall be agreed upon by you and the Company (such time and date of payment and delivery being herein called “Closing Time”).

     In addition, in the event that any or all of the Option Securities are purchased by the Underwriter, payment of the purchase price for, and delivery of certificates for, such Option Securities shall be made at the above-mentioned offices, or at such other place as shall be agreed upon by you and the Company, on each Date of Delivery as specified in the notice from you to the Company.

     Payment shall be made to the Company by wire transfer of immediately available funds to a bank account designated by the Company, against delivery through the facilities of DTC to the Underwriter of certificates for the Securities to be purchased by them.

     (d) Denominations; Registration. Certificates for the Initial Securities and the Option Securities, if any, shall be in such denominations and registered in such names as the Underwriter may request in writing at least one full business day before the Closing Time or the relevant Date of Delivery, as the case may be. The certificates for the Initial Securities and the Option Securities, if any, will be made available for examination and packaging by the Underwriter in The City of New York not later than 10:00 a.m. (Eastern time) on the business day prior to the Closing Time or the relevant Date of Delivery, as the case may be.

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

     (a) Delivery of Registration Statements. The Company has furnished or will deliver to the Underwriter and counsel for the Underwriter, without charge, copies of the Registration Statement as originally filed and of each amendment thereto (including exhibits filed therewith or incorporated by reference therein and documents incorporated or deemed to be incorporated

by reference therein) and copies of all consents and certificates of experts. The copies of the Registration Statement and each amendment thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T of the Commission.

     During the period when the Prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, the Company will inform the Underwriter of its intention to file any amendment to the Registration Statement or any supplement to the Prospectus; will furnish the Underwriter with copies of any such amendment or supplement a reasonable time in advance of filing; and will not file any such amendment or supplement in a form to which the Underwriter or counsel to the Underwriter shall reasonably object (it being understood that the terms “amendment” and “supplement” do not include documents filed by the Company pursuant to the 1934 Act).

     (b) Delivery of Prospectus. The Company has delivered to the Underwriter, without charge, as many copies of each preliminary prospectus as such Underwriter reasonably requested, and the Company hereby consents to the use of such copies for purposes permitted by the 1933 Act. The Company will furnish to the Underwriter, without charge, during the period when the Prospectus is required to be delivered under the 1933 Act or the 1934 Act, such number of copies of the Prospectus (as amended or supplemented) as such Underwriter may reasonably request. The Prospectus and any amendments or supplements thereto furnished to the Underwriter will be identical to the electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T of the Commission.

     (c) Continued Compliance with Securities Laws. The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the rules and regulations of the Commission thereunder (the “1934 Act Regulations”), so as to permit the completion of the distribution of the Securities as contemplated in this Agreement and in the Prospectus, except where the failure to comply will not adversely affect the distribution of the Securities. If at any time when a prospectus is required by the 1933 Act to be delivered in connection with sales of the Securities, any event shall occur or condition shall exist as a result of which it is necessary for the Company to amend the Registration Statement or amend or supplement the Prospectus in order that the Prospectus will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein not misleading in the light of the circumstances existing at the time it is delivered to a purchaser, or if it shall be necessary at any such time to amend the Registration Statement or amend or supplement the Prospectus in order to comply with the requirements of the 1933 Act or the 1933 Act Regulations, the Company will promptly prepare and file with the Commission, such amendment or supplement as may be necessary to correct such statement or omission or to make the Registration Statement or the Prospectus comply with such requirements, and the Company will furnish to the Underwriter such number of copies of such amendment or supplement as the Underwriter may reasonably request.

SECTION 6. Indemnification.

     (a) Indemnification of Underwriter. The Company and the Operating Partnership each agree to indemnify and hold harmless the Underwriter, its officers or directors, and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, as follows:

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

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

     (iii) against any and all expense whatsoever, as incurred (including, subject to Section 6(c) hereof, the reasonable fees and disbursements of counsel chosen by the Underwriter), reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above;

          provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Company by the Underwriter expressly for use in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment or supplement thereto); and provided, further, that the Company shall not be liable to the Underwriter under the indemnity agreement in this subsection (a) to the extent that any such loss, claim, damage or liability of such Underwriter results from the fact that such Underwriter sold Securities to a person to whom there was not sent or given, at or prior to the written confirmation of such sale, a copy of the Prospectus or the Prospectus as then amended or supplemented (excluding documents incorporated by reference) in any case where such delivery is required by the 1933 Act and the untrue statement or omission of a material fact contained in the Prospectus, any such amendment or supplement thereto or any such other document was corrected in the Prospectus or the Prospectus as then amended or supplemented if the Company has furnished prior to such confirmation sufficient copies thereof to such Underwriter.

     (b) Indemnification of Company, Operating Partnership, Trustees, Partners and Officers. The Underwriter agrees to indemnify and hold harmless the Company, the Operating Partnership, their respective trustees, partners or officers, including without limitation, each of the officers who signed the Registration Statement, and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Registration Statement (or any amendment thereto), or any preliminary prospectus or the Prospectus (or any amendment thereto) in reliance upon and in conformity with written information furnished to the Company or the Operating Partnership by such Underwriter expressly for use in the Registration Statement (or any amendment thereto) or such preliminary prospectus or the Prospectus (or any amendment thereto).

     (c) Actions against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder, but failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability hereunder to the extent it is not materially prejudiced as a result thereof and in any event shall not relieve it from any liability which it may have otherwise than on account of this indemnity agreement. In the case of parties indemnified pursuant to Section 6(a) above, counsel to the indemnified parties shall be selected by the Underwriter, and, in the case of parties indemnified pursuant to Section 6(b) above, counsel to the indemnified parties shall be selected by the Company. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying parties be liable for fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for all indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

     (d) Settlement without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel in accordance with Section 6(a)(iii) hereof, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being

entered into, (iii) such indemnifying party, if it has not theretofore paid such reimbursement, is requested again to pay reimbursement at least five, but not more than ten, days prior to such settlement being entered into, and (iv) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

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

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

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

     The Company and the Underwriter agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

     Notwithstanding the provisions of this Section 7, the Underwriter shall not be required to contribute any amount in excess of the amount by which the total price at which the Securities underwritten by it and distributed to the public were offered to the public exceeds the amount of

any damages which such Underwriter has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

     For purposes of this Section 7, each officer or director, as the case may be, of the Underwriter and each person, if any, who controls the Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as such Underwriter, and each trustee, partner or officer, as the case may be, of the Company or the Operating Partnership, including without limitation each officer who signed the Registration Statement, and each person, if any, who controls the Company or the Operating Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same rights to contribution as the Company or the Operating Partnership, as the case may be.

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

     SECTION 9. Termination of Agreement.

     (a) Termination; General. The Underwriter may terminate this Agreement, by notice to the Company, at any time at or prior to Closing Time (i) if there has been, since the time of execution of this Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in or affecting the condition, financial or otherwise, or the earnings or business affairs of the Company and its subsidiaries taken as a whole, whether or not arising in the ordinary course of business, or (ii) if there has occurred any material adverse change in the financial markets in the United States, or any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions, in each case the effect of which is such as to make it, in the judgment of the Underwriter, impracticable or inadvisable to commence or continue the offering of the Securities to the public or to enforce contracts for the sale of the Securities, or (iii) if trading in any securities of the Company has been suspended or materially limited by the Commission or the New York Stock Exchange, or if trading generally on the American Stock Exchange or the New York Stock Exchange has been suspended or materially limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of such exchanges or by order of the Commission or any other governmental authority, or (iv) if a banking moratorium has been declared by either Federal or New York authorities or (v) there shall have been any downgrading in the rating assigned to the Securities or any of the Company’s other securities by any “nationally recognized

statistical rating organization” (as defined for purposes of Rule 436(g) under the Act) or any notice given of any intended or potential downgrading in any such rating.

     (b) Liabilities. If this Agreement is terminated pursuant to this Section, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof, and provided further that Sections 1, 6, 7 and 8 shall survive such termination and remain in full force and effect.

     SECTION 10. Default by the Underwriter.

     (a) If the Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Underwriter may in its discretion arrange for another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by the Underwriter the Underwriter does not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of thirty-six hours within which to procure another party or other parties to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Underwriter notifies the Company that it has so arranged for the purchase of such Securities, or the Company notifies the Underwriter that it has so arranged for the purchase of such Securities, the Underwriter or the Company shall have the right to postpone the Closing Time for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the opinion of the Underwriter may thereby be made necessary. The term “Underwriter” as used in the Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement.

     (b) If, after giving effect to any arrangements for the purchase of the Securities of the defaulting Underwriter by the Company, as provided in subsection (a) above, the number of Securities which remains unpurchased exceeds one-tenth of the number of the Securities to be purchased on such date, then this Agreement shall thereupon terminate, without liability on the part of the Company, except for the expenses to be borne by the Company and the Underwriter provided in Section 4 hereof and the indemnity and contribution agreements in Sections 6 and 7 hereof; but nothing herein shall relieve the defaulting Underwriter from liability for its default.

     SECTION 11. Notices. All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given if mailed or transmitted by any standard form of telecommunication. Notices to the Underwriter shall be directed to General Counsel, Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York 10013, and by facsimile to ###-###-####, attention General Counsel; and notices to the Company and the Operating Partnership shall be directed to it at 888 Seventh Avenue, New York, New York 10019, attention of the Executive Vice President — Finance and Administration, Chief Financial Officer.

     SECTION 12. Parties. This Agreement shall inure to the benefit of and be binding upon the Underwriter, the Company, the Operating Partnership and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any

person, firm or corporation, other than the Underwriter, the Company, the Operating Partnership and their respective successors and the controlling persons and officers, trustees and partners referred to in Sections 6 and 7 and their heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Underwriter, the Company, the Operating Partnership and their respective successors, and said controlling persons and officers, trustees and partners and their heirs and legal representatives, and for the benefit of no other person, firm or corporation.
