Citigroup Global Markets Inc.

▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇

▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇

Ladies and Gentlemen:

Vornado Realty L.P., a Delaware limited partnership (the “Company”), confirms its agreement with Citigroup Global Markets Inc. (the “Underwriter”), with respect to the issue and sale by the Company and the purchase by the Underwriter of $500,000,000 aggregate principal amount of 3.875% Exchangeable Senior Debentures due 2025, of the Company (“Debentures”), and with respect to the grant by the Company to the Underwriter of the option described in Section 2(b) hereof to purchase all or any part of $75,000,000 additional aggregate principal amount of Debentures to cover over-allotments, if any. The aforesaid $500,000,000 aggregate principal amount of Debentures (the “Initial Securities”) to be purchased by the Underwriter and all or any part of the $75,000,000 aggregate principal amount of Debentures subject to the option described in Section 2(b) hereof (the “Option Securities”) are hereinafter called collectively the “Securities.”

The Securities are to be issued under the Indenture, dated as of November 25, 2003 (the “Indenture”), between the Company and The Bank of New York, as Trustee (the “Trustee”). The Securities will be exchangeable in accordance with their terms and the terms of the Indenture into common shares of beneficial interest, par value $0.04 per share (the “Common Shares”), of Vornado Realty Trust, a Maryland real estate investment trust (the “Trust”).

The Company and the Trust understand that the Underwriter proposes to offer the Securities (the “Offering”) as soon after the execution and delivery hereof as in the judgment of the Underwriter is advisable.

Any holder of Securities that receives, upon exchange of their Securities, unregistered Common Shares will have the registration rights set forth in the registration rights agreement (the “Registration Rights Agreement”), to be dated the Closing Date, among the parties hereto. Pursuant to the Registration Rights Agreement, the Trust will use its commercially reasonable efforts to file with the Securities and Exchange Commission (the “Commission”) a registration statement providing for the resale of Common Shares of the Trust by holders of Securities that exchange their Securities and receive in exchange unregistered Common Shares of the Trust, and

to use its commercially reasonable efforts to cause such Registration Statement to be declared and remain effective and usable for the periods, and upon the terms, specified in the Registration Rights Agreement.

The Company and the Trust have filed with the Commission one or more registration statements on Form S-3, including a prospectus relating to the Debentures, the Common Shares issuable upon the exchange of the Debentures and other securities of the Company and the Trust 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 and the Trust 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 (“▇▇▇▇▇”).

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.

(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 ▇▇▇▇▇, 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 and the Trust will inform the Underwriter of their respective 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 or the Trust pursuant to the 1934 Act).

(b) Delivery of Prospectus. 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 the 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 ▇▇▇▇▇, except to the extent permitted by Regulation S-T of the Commission.

(c) Continued Compliance with Securities Laws. The Company and the Trust 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 or the Trust 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 or the Trust, as applicable, 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.

(d) Rule 158. The Company and the Trust 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.

(e) Use of Proceeds. The Company will use the net proceeds received by it from the sale of the Securities in the manner specified in the Prospectus under “Use of Proceeds.”

(f) Reserved Common Shares. The Trust shall reserve and keep available at all times, free of preemptive rights, a sufficient number of Common Shares for the purpose of enabling the Company to deliver, at its election, Common Shares upon the exchange of the Debentures.

SECTION 4. Payment of Expenses.

(a) Expenses. The Company will pay all expenses incident to the performance of its obligations under this Agreement, including (i) the preparation, printing and filing of the Registration Statement (including financial statements and exhibits) as originally filed and of each amendment thereto, (ii) the preparation and printing of the Indenture, this Agreement and such other documents as may be required in connection with the offering, purchase, sale, issuance or delivery of the Securities, (iii) the preparation, issuance and delivery of the certificates for the Securities to DTC or its designated custodian or the Underwriter, including any stock or other transfer taxes and any stamp or other duties payable upon the sale, issuance or delivery of the Securities to the Underwriter, (iv) the fees and disbursements of the Company’s counsel and accountants, (v) the qualification, if any, of the Securities under state securities laws, including filing fees and the reasonable fees and disbursements of counsel for the Underwriter in connection therewith and in connection with the preparation of a Blue Sky Survey and any supplement thereto, if any, (vi) the printing and delivery to the Underwriter of copies of the Prospectus and any amendments or supplements thereto, (vii) the fees and expenses of any transfer agent or registrar for the Securities, and (viii) the filing fees incident to, and the reasonable fees and disbursements of counsel to the Underwriter in connection with, the review, if any, by the National Association of Securities Dealers, Inc. (the “NASD”) of the terms of the sale of the Securities. It is understood, however, that, except as provided in this Section and Section 6 hereof, each Underwriter will pay all of its own costs and expenses, including the fees of its counsel, stock or other transfer taxes on resale of any of the Securities by it, and any advertising expenses connected with any offers of the Securities the Underwriter may make.

(b) Termination of Agreement. If this Agreement is terminated by the Underwriter in accordance with the provisions of Section 5 or Section 9(a)(i) hereof, the Company shall reimburse the Underwriter for all reasonable out-of-pocket expenses, including the reasonable fees and disbursements of counsel for the Underwriter.

SECTION 5. Conditions of Underwriter’s Obligations. The obligations of the Underwriter hereunder are subject to the accuracy of the representations and warranties of the Company contained in Section 1 hereof or in certificates of any officer of the Trust or any subsidiary of the Company delivered pursuant to the provisions hereof, to the performance by the Company of its covenants and other obligations hereunder, and to the following further conditions:

At Closing Time, the Underwriter shall have received the opinion and letter, dated as of Closing Time, of ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Company, in form and substance reasonably satisfactory to counsel for the Underwriter, to the effect set forth in Exhibit A hereto.

(f) Accountants’ Comfort Letter. At the time of the execution of this Agreement, the Underwriter shall have received from Deloitte & Touche LLP a letter dated such date, in form and substance satisfactory to the Underwriter, containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus.

At Closing Time, the Securities shall be rated at least investment grade by ▇▇▇▇▇’▇ Investor’s Service and by Standard & Poor’s Ratings Group, a division of ▇▇▇▇▇▇-▇▇▇▇, Inc.; and since the date of this Agreement, there shall not have occurred a downgrading in the rating assigned to the Securities or any of the Company’s or the Trust’s other securities by any “nationally recognized statistical rating organization,” as that term is defined by the Commission for purposes of Rule 436(g)(2) under the 1933 Act. For purposes of this Section 5(h), a “downgrading in the rating” shall not include any of the following: (i) any notice given of any potential downgrading in any such rating, or (ii) any notice of a possible change in any such rating that does not indicate the direction of the possible change.

(k) Termination of Agreement. If any condition specified in this Section shall not have been fulfilled when and as required to be fulfilled, this Agreement, or, in the case of any condition to the purchase of Option Securities on a Date of Delivery which is after the Closing Time, the obligations of the Underwriter to purchase the relevant Option Securities, may be terminated by the Underwriter by notice to the Company or the Trust at any time at or prior to Closing Time or such Date of Delivery, as the case may be, and such termination shall be without liability of any party to any other party except as provided in Section 4 and except that Sections 1, 6, 7 and 8 shall survive any such termination and remain in full force and effect.

SECTION 6. Indemnification.

(a) Indemnification of Underwriter. The Company agrees 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 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 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 the Underwriter results from the fact that the 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 the Underwriter.

(b) Indemnification of Company, Trust, Partners, Trustees and Officers. The Underwriter agrees to indemnify and hold harmless the Company and the Trust, their respective partners, trustees or officers, including without limitation, each of the officers of the Trust who signed the Registration Statement, and each person, if any, who controls the Company 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 the Prospectus (or any amendment thereto) 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 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 and the Trust 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 and the Trust 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 and the Trust 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 and the Trust 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 the Trust 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, the Trust 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 the 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 ▇▇▇▇ ▇▇▇) 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 the Underwriter, and each partner, trustee or officer, as the case may be, of the Company or the Trust, including without limitation each officer of the Trust who signed the Registration Statement, and each person, if any, who controls the Company or the Trust 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 Trust, 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 Trust 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 Trust or any officer or partner or trustee or controlling person of the Company or the Trust, 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 or the Trust, 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, the Trust and their respective 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 or the Trust 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) 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 or the Trust’s other securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Act). For purposes of this Section 9(a), a “downgrading in the rating” shall not include any of the following: (i) any notice given of any potential downgrading in any such rating, or (ii) any notice of a possible change in any such rating that does not indicate the direction of the possible change.

(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. Intentionally Omitted.

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 the General Counsel of Citigroup Global Markets Inc., ▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇; and notices to the Company and the Trust shall be directed to it at ▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, 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 Trust 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 Trust 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 Trust 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. No purchaser of Securities from the Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 13. Governing Law and Time. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK. SPECIFIED TIMES OF DAY REFER TO NEW YORK CITY TIME.

SECTION 14. Effect of Headings. The Article and Section headings herein and the Table of Contents are for convenience only and shall not affect the construction hereof.

If the foregoing is in accordance with your understanding of our agreement, please sign and return to the Company a counterpart hereof, whereupon this instrument, along with all counterparts, will become a binding agreement among the Underwriter, the Company and the Trust in accordance with its terms.
