12

If the delivery of a prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) continues to be required in connection with the offering of the Securities, the Company will inform the Representatives of its intention to file any amendment to the Registration Statement or any supplement to the Final Prospectus; will furnish the Representatives 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 Representatives or counsel to the Underwriters 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)                                  Final Term Sheet . The Company will prepare a final term sheet containing solely the final pricing terms of the Securities in a form approved by the Representatives and contained in Schedule D hereof and file such term sheet pursuant to Rule 433(d) of the 1933 Act within the time required by such rule.

(d)                                  Modification of Disclosure Package .  If there occurs an event or development as a result of which the Disclosure Package would include an untrue statement of a material fact or would 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, the Company will notify promptly the Representatives so that any use of the Disclosure Package may cease until it is amended or supplemented.

(e)                                   Continued Compliance with Securities Laws .  The Company will comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and the 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 Disclosure Package

and the Final 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 Final Prospectus in order that the Final 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 such Final Prospectus (or in lieu thereof, the notice referred to in Rule 173(a) under the 1933 Act) 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 Final 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 Final Prospectus comply with such requirements, and the Company will furnish to the Underwriters such number of copies of such amendment or supplement as the Underwriters may reasonably request.

(f)                                    Rule 158 .  The Company will timely file such reports pursuant to the 1934 Act as are necessary in order to make generally available to its security holders as soon as practicable an earnings statement for the purposes of, and to provide the benefits contemplated by, the last paragraph of Section 11(a) of the 1933 Act and the 1933 Act Regulations relating thereto.

(i)                                      Limitation on Free Writing Prospectuses .  The Company agrees that, unless it obtains the prior written consent of the Representatives, and each Underwriter, severally and not jointly, agrees with the Company that, unless it has obtained or will obtain, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405 of the 1933 Act Regulations) required to be filed by the Company with the Commission or retained by the Company under Rule 433 of the 1933 Act Regulations, other than the final term sheet prepared and filed pursuant to Section 3(b) hereof; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule C hereto. Any such free writing prospectus consented to by the Representatives or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.”  The Company agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 of the 1933 Act Regulations applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(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 the Basic Prospectus, the Pricing Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the information

18

contained in the final term sheet required to be prepared and filed pursuant to Section 3(b) hereof, or in 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 Representatives), 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 any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto), or the Basic Prospectus, the Pricing Prospectus, the Final Prospectus, any Issuer Free Writing Prospectus or the information contained in the final term sheet required to be prepared and filed pursuant to Section 3(b) hereof, or in any amendment or supplement thereto); and provided , further , that the foregoing indemnity agreement by the Company shall not inure to the benefit of any Underwriter from whom the person asserting any losses, claims, damages or liabilities otherwise covered by this paragraph purchased Securities if the Company shall have furnished to the Underwriters prior to the Applicable Time a copy of a Free Writing Prospectus, if any, or Pricing Prospectus (as then amended and supplemented), and such document was not sent or given by or on behalf of such Underwriter to such person if required so to have been delivered, and if such Free Writing Prospectus, if any, or Pricing Prospectus (as so amended or supplemented) would have cured the defect giving rise to such loss, expense, claim, damage or liability or such loss, expense, claim, damage or liability arises from the continued use by such Underwriter of the Disclosure Package following its receipt of notice of an event or occurrence pursuant to Section 3(d).

(b)                                  Indemnification of Company, Operating Partnership, Trustees, Partners and Officers .  Each Underwriter severally 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

19

Registration Statement (or any amendment thereto), or the Pricing Prospectus or the Final Prospectus, or in any amendment or supplement thereto in reliance upon and in conformity with written information furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or the Basic Prospectus, the Pricing Prospectus or the Final Prospectus, or in any amendment or supplement 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 Representatives, 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.  Subject to Section 6(d), 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

20

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 Underwriters 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 Underwriters 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 Underwriters 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 Underwriters, in each case as set forth on the cover of the Final Prospectus, 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 Underwriters 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 Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Company and the Underwriters 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, no Underwriter shall 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.

21

For purposes of this Section 7, each officer or director of each Underwriter and person, if any, who controls an 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 9.                                                     Termination of Agreement .

(a)                                  Termination; General .  The Representatives 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 Disclosure Package and the Final 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 Representatives, 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 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) if, since the time of execution of this Agreement, 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 such term is defined pursuant to Section 3(a)(62) of the 1934 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, 8 and 15 shall survive such termination and remain in full force and effect.

22

SECTION 10.                                              Default by One or More of the Underwriters .

(a)                                  Substitution of Defaulting Underwriters .  If any Underwriter shall default in its obligation to purchase the Securities which it has agreed to purchase under this Agreement, the Representatives may in their discretion arrange for themselves or another party or other parties to purchase such Securities on the terms contained herein. If within thirty-six hours after such default by any Underwriter the Representatives do 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 satisfactory to the Representatives to purchase such Securities on such terms. In the event that, within the respective prescribed periods, the Representatives notify the Company that they have so arranged for the purchase of such Securities, or the Company notifies the Representatives that it has so arranged for the purchase of such Securities, the Representatives 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, the Disclosure Package or the Final Prospectus, or in any other documents or arrangements, and the Company agrees to file promptly any amendments or supplements to the Registration Statement, the Disclosure Package or the Final Prospectus which in the opinion of the Representatives 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)                                  Purchase by Non-Defaulting Underwriters .  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives or the Company, or both, as provided in subsection (a) above, the number of Securities which remains unpurchased does not exceed one-tenth of the number of the Securities to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the full  amount of Securities which such Underwriter agreed to purchase under this Agreement and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Securities which such Underwriter agreed to purchase under this Agreement) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)                                   Termination .  If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the Representatives or the Company, or both, 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, or if the Company shall not exercise the right described in subsection (b) above to require non-defaulting Underwriters to purchase Securities of a defaulting Underwriter or Underwriters, then this Agreement shall thereupon terminate, without liability on the party of any non-defaulting Underwriter or the Company, except for the expenses to be borne by the Company and the Underwriters provided in Section 4 hereof and the indemnity and contribution agreements in Sections 6 and 7 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(i)                                      The Company is a real estate investment trust duly formed and existing under the laws of the State of Maryland and is in good standing with the State Department of Assessments and Taxation of Maryland;

(ii)                                   The Company has the trust power to own, lease and operate its properties and to conduct its business substantially as described in the Disclosure Package and the Final Prospectus under the heading “Vornado Realty Trust and Vornado Realty L.P.” and to enter into and perform its obligations under this Agreement;

(iii)                                The Operating Partnership is a limited partnership existing under the laws of the State of Delaware and has the partnership power and authority to own, lease and operate its properties and conduct its business substantially as described in the Disclosure Package and the Final Prospectus;

(v)                                  This Agreement has been duly authorized, executed and delivered by the Company and the Operating Partnership;

(vi)                               The Registration Statement became effective upon filing under the 1933 Act, and, to the best of such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or are pending under the 1933 Act;

(vii)                            All regulatory consents, authorizations, approvals and filings required to be obtained or made by the Company under the Covered Laws for the execution and delivery by the Company of, and the performance by the Company of its obligations under, this Agreement have been obtained or made;

(viii)                         The execution and delivery by the Company and the Operating Partnership of, and the performance by the Company of its obligations under, this Agreement will not violate any Covered Laws.

(ix)                               The execution and delivery by the Company and the Operating Partnership of, and the performance by the Company of its obligations under, this Agreement will not (A) violate the Company’s Declaration of Trust or Bylaws or the certificate of limited partnership of the Operating Partnership, in each case as amended and as in effect on the Closing Time or the Date of Delivery, as applicable, or (B) result in a default under or breach or violation of the agreements filed as exhibit Nos. 10.1 through 10.29 inclusive, to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016; provided, however, that such counsel may express no opinion in clause (B) as to

1

compliance with any financial or accounting test, or any limitation or restriction expressed as a dollar amount, ratio or percentage;

(x)                                  Such counsel shall confirm the opinion that, commencing with its taxable year ending December 31, 1993, the Company has been organized in conformity with the requirements for qualification as a REIT under the Code, its manner of operations has enabled it to satisfy the requirements for qualification as a REIT for taxable years ending on or prior to the date hereof and its proposed method of operations will enable it to satisfy the current requirements for qualification and taxation as a REIT for subsequent taxable years; in providing such opinion, such counsel may rely (i) without independent investigation, upon the statements and representations contained in certificates provided by the Company, Two Penn Plaza REIT, Inc., SO Hudson Westside I Corp., H Street Building Corporation, Universal Building, Inc., VCP One Park Parallel REIT LLC, VNO Capital Partners REIT LLC, Vornado Capital Partners Parallel REIT LLC, Vornado Warner LLC, Vornado 17th Street LLC, 280 Park REIT LLC, CPTS Parallel Owner LLC, CPTS Domestic Owner LLC, 11 East 68th REIT LLC, 11 East 68th Parallel REIT LLC, 501 Broadway REIT LLC, 501 Broadway Parallel REIT LLC, Lincoln Road REIT LLC, Lincoln Road Parallel REIT LLC, CP Culver City REIT LLC, CP Culver City Parallel REIT LLC, Going Away LLC, 6M REIT LLC, Shenandoah Parent LLC, Skyline Parent LLC, and 7 West 34th Street Sub LLC, (ii) without independent investigation, upon statements and representations contained in certificates provided by Alexander’s, Inc. and Americold Realty Trust, (iii) without independent investigation, upon an opinion of Shearman & Sterling  concerning the qualification of Alexander’s as a REIT for federal income tax purposes and upon an opinion of Paul Hastings LLP concerning the qualification of Lexington Realty Trust as a REIT for federal income tax purposes, and (iv) without independent investigation upon any other certificates or opinions of counsel as deemed necessary or appropriate in rendering such opinion and subject to an analysis of the Code, Treasury Regulations thereunder, judicial authority and current administrative rulings and such other laws and facts as deemed relevant and necessary; and

(xi)                               Neither the Company nor the Operating Partnership is, and solely after giving effect to the offering and sale of the Securities and the application of proceeds thereof as described in the Disclosure Package and the Final Prospectus, will be an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended.

In giving this opinion, Sullivan & Cromwell LLP may state that it expresses no opinion in paragraphs (vii) and (viii) above, insofar as performance by the Company of its obligations under this Agreement is concerned, as to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights; for purposes of the opinions in paragraphs (vii) and (viii) above, “Covered Laws” means the Federal laws of the United States, the laws of the State of New York and, with respect to the Operating Partnership, the provisions of the Revised Uniform Limited Partnership Act of the State of Delaware (including the published rules or regulations thereunder) that in such counsel’s experience normally are applicable to general business entities and transactions such as those contemplated by this

A- 2

Agreement; provided , however , that such term does not include Federal or state securities laws, other antifraud laws and fraudulent transfer laws, tax laws, the Employee Retirement Income Security Act of 1974, antitrust laws or any law that is applicable to the Company, the Operating Partnership, this Agreement or the transactions contemplated hereby solely as part of a regulatory regime applicable to the Company, the Operating Partnership or their respective affiliates due to its or their status, business or assets. Such counsel may also state that its opinion is limited to the Federal laws of the United States of America, the laws of the State of New York, the laws of the State of Maryland and the Revised Uniform Limited Partnership Act of the State of Delaware, such counsel may rely as to matters of Maryland law on the opinion of Venable LLP and state that its opinion is subject to the same assumptions, qualifications and limitations with respect to such matters as are contained in such opinion of Venable LLP and such counsel may express no opinion as to the effect of the laws of any other jurisdiction; and such counsel may rely as to certain matters upon information obtained from public officials, officers of the Company and its subsidiaries and other sources believed by them to be responsible.  Such counsel may assume that the certificates for the Securities conform to the specimen thereof examined by them and have been duly countersigned by a transfer agent of the Securities, that this Agreement has been duly authorized, executed and delivered by the Underwriters and that the signatures on all documents examined by them are genuine, assumptions which such counsel need not independently verify.

FORM OF LETTER OF COMPANY’S COUNSEL
TO BE DELIVERED PURSUANT
TO SECTION 5(b)

(i)                                      On the basis of the information that was gained in the course of the performance of the services referred to in their letter, considered in the light of their understanding of the applicable law (including the requirements of Form S-3 and the character of the prospectus contemplated thereby) and the experience they have gained through their practice under the 1933 Act, such counsel are of the opinion that the Registration Statement, as of the date of the Final Prospectus, and the Final Prospectus, as of its date, appeared on their face to be appropriately responsive, in all material respects relevant to the offering of the Securities, to the requirements of the 1933 Act and the 1933 Act Regulations; and that nothing that came to their attention in the course of their review has caused them to believe that, insofar as relevant to the offering of the Securities, the Registration Statement, as of the date of the Final Prospectus, contained any untrue statement of a material fact or omitted to state any material fact required to be stated therein or necessary to make the statements therein not misleading or that the Disclosure Package, as of the Applicable Time (which counsel has been informed is prior to the time of the first sale of the Securities), or that the Final Prospectus, as of its date, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; also, nothing that has come to such counsel’s attention in the course of certain procedures (as described in such opinion) which has caused such counsel to believe that, insofar as relevant to the offering of the Securities, the Disclosure Package or the Final Prospectus, as of the date and time of delivery of such letter, contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that such opinion may state that the limitations inherent in the independent verification of factual matters and the character of determinations involved in the registration process are such that such counsel does not assume any responsibility for the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Disclosure Package or the Final Prospectus, except for those made under the captions “Description of Shares of Beneficial Interest of Vornado Realty Trust — Description of Preferred Shares of Beneficial Interest of Vornado Realty Trust” and “Federal Income Tax Considerations” in the Basic Prospectus and “Description of the Series M Preferred Shares” and “Additional U.S. Federal Income Tax Considerations” in the Disclosure Package and the Final Prospectus insofar as they relate to the provisions of documents or United States Federal tax law therein described, and that such counsel does not express any opinion or belief as to the financial statements or schedules or other financial data derived from accounting records contained in the Registration Statement, the Disclosure Package or the Final Prospectus, or as to the report of management’s assessment of the effectiveness of internal control over financial reporting or the auditors’ attestation report on the effectiveness of internal control over financial reporting.

(ii)                                   Such counsel does not know of any pending legal proceedings against the Company or any of its consolidated subsidiaries that would be required to be disclosed in

A- 4

the Basic Prospectus, as supplemented by the Final Prospectus, and is not so disclosed; and, insofar as relevant to the offering of Securities, such counsel does not know of any documents that are required to be filed as exhibits to the Registration Statement and are not so filed.
