Ladies and Gentlemen:

Reckson Operating Partnership, L.P., a Delaware limited partnership (the “Operating Partnership”), proposes to issue and sell up to $275,000,000 aggregate initial public offering price of its debt securities (“Debt Securities”) from time to time, in or pursuant to one or more offerings on terms to be determined at the time of sale.

The terms and rights of any particular issuance of Debt Securities shall be as specified in the Terms Agreement (as defined below) relating thereto and in or pursuant to the indenture and any supplements or amendments thereto (the “Indenture”) identified in such Terms Agreement.

Whenever the Operating Partnership determines to make an offering of Debt Securities through Citigroup Global Markets Inc. and ▇▇▇▇▇▇▇, Sachs & Co. (the “Representatives”) or through an underwriting syndicate managed by the Representatives, the Operating Partnership will enter into an agreement (each, a “Terms Agreement”) providing for the sale of such Debt Securities to, and the purchase and offering thereof by, the Representatives and such other underwriters, if any, selected by the Representatives as have authorized the Representatives to enter into such Terms Agreement on their behalf (the “Underwriters,” which term shall include the Representatives whether acting alone in the sale of the Underwritten Securities (as defined herein) or as a member of an underwriting syndicate or any Underwriter substituted pursuant to Section 10 hereof); provided, that the Operating Partnership is not obligated, and shall have complete and absolute discretion to determine if and when, to make any offering, to make any offering through the Representatives or any other person, or to enter into any Terms Agreement. Prior to execution of a Terms Agreement, this Underwriting Agreement shall not be construed as an obligation of the Operating Partnership to sell any Debt Securities or as an obligation of any of the Underwriters to purchase Debt Securities. The obligation of the Operating Partnership to issue and sell any Debt Securities and the obligation of any of the Underwriters to purchase any

Debt Securities shall be evidenced by the Terms Agreement with respect to the Underwritten Securities specified therein. The Terms Agreement relating to the offering of Debt Securities shall specify the aggregate principal amount of Debt Securities to be initially issued (the “Initial Underwritten Securities”), the name of each Underwriter participating in such offering (subject to substitution as provided in Section 10 hereof), the aggregate principal amount of Initial Underwritten Securities which each such Underwriter severally agrees to purchase, whether such offering is on a fixed or variable price basis and, if on a fixed price basis, the initial offering price, the price at which the Initial Underwritten Securities are to be purchased by the Underwriters, the form, time, date and place of delivery and payment of the Initial Underwritten Securities and any other material variable terms of the Initial Underwritten Securities. In addition, if applicable, such Terms Agreement shall specify whether the Operating Partnership has agreed to grant to the Underwriters an option to purchase additional Debt Securities to cover over-allotments, if any, and the aggregate principal amount of Debt Securities subject to such option (the “Option Underwritten Securities”). As used herein, the term “Underwritten Securities” shall include the Initial Underwritten Securities and all or any portion of any Option Underwritten Securities. The Terms Agreement, which shall be substantially in the form of Exhibit A hereto, may take the form of an exchange of any standard form of written telecommunication among the Operating Partnership and the Representatives, acting for themselves and, if applicable, as Representatives of any other Underwriters. Each offering of Underwritten Securities will be governed by this Underwriting Agreement, as supplemented by the applicable Terms Agreement.

Each of the Operating Partnership and the Subsidiaries possesses such certificates, permits, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to conduct the business now operated by them except for such Governmental Licenses, the failure to obtain would not, singly or in the aggregate, result in a Material Adverse Effect. The Operating Partnership and the Subsidiaries are in compliance with the terms and conditions of all such Governmental Licenses, except where the failure so to comply would not, singly or in the aggregate, result in a Material Adverse Effect. All of the Governmental Licenses are valid and in full force and effect, except where the invalidity of such Governmental Licenses or the failure of such Governmental Licenses to be in full force and effect would not result in a Material Adverse Effect. Neither the Operating Partnership nor any Subsidiary has received any notice of proceedings relating to the revocation or modification of any such Governmental Licenses which, singly or in the aggregate, if the subject of an unfavorable decision, ruling or finding, would result in a Material Adverse Effect.

Each of the Properties comply with all applicable codes, laws and regulations and (including, without limitation, building and zoning codes, laws and regulations and laws relating to access to the Properties), except if and to the extent disclosed in the Preliminary Prospectus and except for such failures to comply that would not in the aggregate have a Material Adverse Effect. There are in effect for the assets of each of the Operating Partnership, the Subsidiaries or any joint venture partnership in which the Operating Partnership owns an interest, insurance policies covering the risks and in amounts that are commercially reasonable for the types of assets owned by them and that are consistent with the types and amounts of insurance typically maintained by prudent owners of properties similar to such assets in the markets in which such assets are located, and none of the Operating Partnership, the Subsidiaries or any joint venture partnership in which the Operating Partnership owns an interest has received from any insurance company notice of any material defects or deficiencies affecting the insurability of any such assets or any notices of cancellation or intent to cancel any such policies excluding the notification from the Chubb Group that its current insurance policy will not be renewed upon expiration. The Operating Partnership has no knowledge of any pending or threatened litigation, moratorium, condemnation proceedings, zoning change, or other similar proceeding or action that could in any manner affect the size of, use of, improvements on, construction on, access to or availability of utilities or other necessary services to the Properties, except such proceedings or actions that would not have a Material Adverse Effect.

(21)                            Environmental Laws. Except as otherwise stated in the Registration Statement and the Preliminary Prospectus and except such violations as would not, singly or in the aggregate, result in a Material Adverse Effect, to the knowledge of the Operating Partnership and any Subsidiary, as the case may be, after due inquiry, (A) neither the Operating Partnership nor any Subsidiary is in violation of any federal, state, local or foreign statute, law, rule, regulation, ordinance or code, policy or rule of common law and any judicial or administrative interpretation thereof including any judicial or administrative order, consent, or decree of judgment relating to pollution or protection of human health, the environment (including,

(22)                            Tax Returns. Each of the Operating Partnership and any Subsidiary has filed all federal, state, local and foreign income tax returns which have been required to be filed (except in any case in which an extension has been granted or the failure to so file would not have a Material Adverse Effect) and has paid all taxes required to be paid and any other assessment, fine or penalty levied against it, to the extent that any of the foregoing is due and payable, except, in all cases, for any such tax, assessment, fine or penalty that is being contested in good faith.

(23)                            Environmental Consultants. None of the environmental consultants which prepared environmental and asbestos inspection reports with respect to certain of the Properties was employed for such purpose on a contingent basis or has any substantial interest in the Company, the Operating Partnership or any Subsidiary and none of them or any of their directors, officers or employees is connected with the Company, the Operating Partnership or any Subsidiary as a promoter, selling agent, voting trustee, director, officer or employee.

(24)                            Title Insurance. The Operating Partnership and any Subsidiary, as the case may be, have obtained title insurance on the fee interests and leasehold interests in each of the Properties in an amount at least equal to the greater of (A) the mortgage indebtedness on each such Property and (B) the purchase price paid for each such Property (in the case of any Property having been acquired by the Operating Partnership via an exchange of Units for partnership interests in the entity holding such property, the “purchase price” of such Property being deemed to be the sum of (i) the per-share price of the Common Stock of the Company on the date such Property was exchanged for Units multiplied by the number of Units exchanged for such Property or interests in the entity holding such Property and (ii) the amount of any assumed indebtedness secured by such Property), except that Omni Partnership has obtained title insurance insuring Omni Partnership’s interest in its real property assets in an amount not less than $48 million.

13

has taken or will take, directly or indirectly, any action resulting in a violation of Regulation M under the 1934 Act, or designed to cause or result in, or that has constituted or that reasonably might be expected to constitute, the stabilization or manipulation of the price of any security of the Operating Partnership or the Company to facilitate the sale or resale of the Underwritten Securities.

(26)                            Sarbanes Oxley Act Compliance. There is and has been no failure on the part of the Company and the Operating Partnership to comply in all material respects with the provisions of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations in connection therewith.

(b)                                 Officers’ Certificates. Any certificate signed by any authorized representative of the Operating Partnership and delivered to any Underwriter or to counsel for the Underwriters in connection with the offering of the Underwritten Securities shall be deemed a representation and warranty by such entity or person, as the case may be, to each Underwriter as to the matters covered thereby on the date of such certificate and, unless subsequently amended or supplemented, at each Representation Date subsequent thereto.

SECTION 3.                                Sale and Delivery to Underwriters; Closing.

(a)                                  Underwritten Securities. The several commitments of the Underwriters to purchase the Underwritten Securities pursuant to the applicable Terms Agreement shall be deemed to have been made on the basis of the representations and warranties herein contained and shall be subject to the terms and conditions herein set forth.

(b)                                 Option Underwritten Securities. If so provided in the applicable Terms Agreement and subject to the terms and conditions set forth therein, the Operating Partnership may grant an option to the Underwriters, severally and not jointly, to purchase up to the aggregate principal amount of the Option Underwritten Securities set forth therein at a price per Option Underwritten Security equal to the price per Initial Underwritten Security, less an amount equal to any interest paid or payable on the Initial Underwritten Securities but not payable on the Option Underwritten Securities. Such option, if granted, will expire 30 days after the date of such Terms Agreement, 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 Underwritten Securities upon notice by the Representatives to the Operating Partnership setting forth the aggregate principal amount of Option Underwritten Securities as to which the several Underwriters are then exercising the option and the time, date and place of payment and delivery for such Option Underwritten Securities. Any such time and date of payment and delivery (each, a “Date of Delivery”) shall be determined by the Representatives, 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, unless otherwise agreed upon by the Representatives and the Operating Partnership. If the option is exercised as to all or any portion of the Option Underwritten Securities, each of the Underwriters, severally and not jointly, will purchase that proportion of the total aggregate principal amount of Option Underwritten Securities then being purchased which the aggregate principal amount of Initial Underwritten Securities each such Underwriter has severally agreed to purchase as set forth in such Terms Agreement bears to the total aggregate principal amount of Initial Underwritten Securities,

14

subject to such adjustments as the Representatives in their discretion shall make to eliminate any sales or purchases of a fractional aggregate principal amount of Option Underwritten Securities.

(c)                                  Payment. Payment of the purchase price for, and delivery of, the Initial Underwritten Securities shall be made at the office of Sidley Austin LLP, or at such other place as shall be agreed upon by the Representatives and the Operating Partnership, at 10:00 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 of the applicable Terms Agreement (unless postponed in accordance with the provisions of Section 10 hereof), or such other time not later than ten business days after such date as shall be agreed upon by the Representatives and the Operating Partnership (such time and date of payment and delivery being herein called “Closing Time”). In addition, in the event that the Underwriters have exercised their option, if any, to purchase any or all of the Option Underwritten Securities, payment of the purchase price for, and delivery of such Option Underwritten Securities, shall be made at the above-mentioned offices of Sidley Austin LLP, or at such other place as shall be agreed upon by the Representatives and the Operating Partnership on the relevant Date of Delivery as specified in the notice from the Representatives to the Operating Partnership.

Payment shall be made to the Operating Partnership by wire transfer of Federal funds or similar same day funds payable to the order of the Operating Partnership against delivery to the Representatives for the respective accounts of the Underwriters of the Underwritten Securities to be purchased by them. It is understood that each Underwriter has authorized the Representatives, for their account, to accept delivery of, receipt for, and make payment of the purchase price for, the Underwritten Securities which it has severally agreed to purchase. The Representatives, individually and not as Representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Underwritten Securities to be purchased by any Underwriter whose check has not been received by the Closing Time or the relevant Date of Delivery, as the case may be, but such payment shall not relieve such Underwriter from its obligations hereunder.

(d)                                 Denominations; Registration. The Underwritten Securities shall be in such denominations and registered in such names as the Representatives may request in writing at least one full business day prior to the Closing Time or the relevant Date of Delivery, as the case may be. The Underwritten Securities will be made available for examination and packaging by the Representatives 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 7.                                Indemnification.

(a)                                  Indemnification of Underwriters. The Operating Partnership agrees to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the 1933 Act, and any director, officer, employee or affiliate thereof, as follows:

(1)                                  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), including the information deemed to be part of the Registration Statement pursuant to Rule 430B of the 1933 Act Regulations, if applicable, 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 contained in any Preliminary Prospectus, the Prospectus or any Free Writing 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;

(2)                                  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 of any investigation or proceeding by any governmental agency or body, commenced or threatened, or of any claim whatsoever for which indemnification is provided under subsection (1) above, if such settlement is effected with the written consent of the indemnifying party, which consent shall not be unreasonably withheld; and

(3)                                  against any and all expense whatsoever (including without limitation, the fees and disbursements of counsel chosen by the Representatives) reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceedings by any governmental agency or body, commenced or threatened, or any claim whatsoever for which indemnification is provided under subsection (1) above, to the extent that any such expense is not paid under subsection (1) or (2) above; provided, however, that the indemnity

24

agreement provided for in this Section 6(a) 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 Operating Partnership by any Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus, the Prospectus or any Free Writing Prospectus (or any amendment or supplement thereto).

(b)                                 Indemnification of the Operating Partnership. Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Operating Partnership , and each person, if any, who controls the Operating Partnership within the meaning of Section 15 of the 1933 Act, and any employee or affiliate thereof, against any and all loss, liability, claim, damage, and expense described in the indemnity contained in subsection (a) of this Section 6, 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, the Prospectus or any Free Writing Prospectus (or any amendment or supplement thereto) in reliance upon and in conformity with written information furnished to the Operating Partnership by such Underwriter through the Representatives expressly for use in the Registration Statement (or any amendment thereto) or any Preliminary Prospectus, the Prospectus or any Free Writing Prospectus (or any amendment or supplement thereto).

(c)                                  Actions against Parties; Notification; Settlement without Consent if Failure to Reimburse. 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 so to notify an indemnifying party shall not relieve such indemnifying party from any liability which it may have otherwise than on account of this indemnity agreement. An indemnifying party may participate at its own expense in the defense of such action. If it so elects within a reasonable time after receipt of such notice, an indemnifying party, jointly with any other indemnifying parties receiving such notice, may assume the defense of such action with counsel chosen by it and reasonably approved by the other indemnifying parties defendant in such action and reasonably approved by the indemnified party (who shall not, except with the consent of the indemnified party, be counsel to an indemnifying party), unless such other indemnifying parties or an indemnified party reasonably object to such assumption on the ground that the named parties to any such action (including any impleaded parties) include both such indemnified party and an indemnifying party, and such indemnified party reasonably believes that there may be legal defenses available to it which are different from or in addition to those available to such indemnifying party. If an indemnifying party assumes the defense of such action, the indemnifying parties shall not be liable for any fees and expenses of counsel for the indemnified parties incurred thereafter in connection with such action. 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 written consent of the indemnified party, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified party is an actual or potential party to such action or claim) unless such settlement, compromise or judgement (i) includes an unconditional

25

release of the indemnified party from all liability arising out of such action 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.

SECTION 8.                                Contribution.

In order to provide for just and equitable contribution in circumstances in which the indemnity agreement 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, the Operating Partnership, on the one hand, and the Underwriters, on the other, shall contribute to the aggregate losses, liabilities claims, damages and expenses of the nature contemplated by said indemnity agreement incurred by the Operating Partnership and the Underwriters, as incurred, in such proportions that the Underwriters are responsible for that portion represented by the percentage that the underwriting discount appearing on the cover page of the Prospectus bears to the initial public offering price appearing thereon and the Operating Partnership are responsible for the balance. If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law or if the indemnified party failed to give the notice required under Section 6(c) above, then each indemnifying party shall contribute to such amount paid or payable by such indemnified party in such proportion as is appropriate to reflect not only such relative benefits allocation referred to in the first sentence of this Section 7 but also the relative fault of the Operating Partnership, on the one hand, and the Underwriters on the other, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Operating Partnership, on the one hand, or such Underwriters, on the other, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Operating Partnership 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 (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to above in this Section 7. The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this Section shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the applicable Underwritten 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 such untrue or alleged untrue statement or omission or alleged omission. Notwithstanding the foregoing, 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, each person, if any, who controls an Underwriter within the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as such Underwriter, and each employee or affiliate of the Operating Partnership and each person, if any, who controls the Operating Partnership, within

26

the meaning of Section 15 of the 1933 Act shall have the same rights to contribution as the Operating Partnership.

The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective underwriting commitments and not joint.

SECTION 9.                                Representations, Warranties and Agreements to Survive Delivery.

All representations, warranties and agreements contained in this Underwriting Agreement or the applicable Terms Agreement or in certificates of officers of the Company, as general partner of the Operating Partnership, submitted pursuant hereto or thereto shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Underwriter or controlling person, or by or on behalf of the Operating Partnership, and shall survive delivery of and payment for the Underwritten Securities.

SECTION 10.                          Termination.

(a)                                  Underwriting Agreement. This Underwriting Agreement (excluding the applicable Terms Agreement) may be terminated for any reason at any time by the Operating Partnership or by the Representatives upon the giving of 30 days’ prior written notice of such termination to the other party hereto.

(b)                                 Terms Agreement. The Representatives may terminate the applicable Terms Agreement, by notice to the Operating Partnership, at any time at or prior to the Closing Time or any relevant Date of Delivery, if (i) there has been, since the time of execution of such Terms Agreement or since the respective dates as of which information is given in the Prospectus, any material adverse change in the condition, financial or otherwise, or in the earnings, business affairs or business prospects of the Operating Partnership and any Subsidiaries considered as one enterprise, whether or not arising in the ordinary course of business, in each case the effect of which is such as to make it, in the judgment of the Representatives, impracticable or inadvisable to market the Underwritten Securities, or (ii) there has occurred any material adverse change in the financial markets in the United States or internationally or any outbreak or escalation of hostilities or acts of terrorism involving the United States or there is a declaration by the United States of a national emergency or war 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 sole judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Underwritten Securities or to enforce contracts for the sale of the Underwritten Securities, or (iii) trading in any securities of the Company or the Operating Partnership has been suspended or limited by the Commission or the New York Stock Exchange, or if trading in securities generally on the New York Stock Exchange or the American Stock Exchange or in the over-the-counter market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by either of said exchanges or by such system or by order of the Commission, the NASD or any other governmental authority, or (iv) a banking moratorium has been declared by either federal or New York state authorities, or a material disruption in clearance or settlement systems has occurred.

27

(c)                                  Liabilities. If this Underwriting Agreement or the applicable Terms Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except as provided in Section 4 hereof; provided that Sections 1, 6, 7, 8 and 15 hereof shall survive such termination and remain in full force and effect.

SECTION 11.                          Default by One or More of the Underwriters.

If one or more of the Underwriters shall fail at the Closing Time or the relevant Date of Delivery, as the case may be, to purchase the Underwritten Securities which it or they are obligated to purchase under the applicable Terms Agreement (the “Defaulted Securities”), then the Representatives shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, or any other underwriters, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representatives shall not have completed such arrangements within such 24-hour period, then:

(a)                                  if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Underwritten Securities to be purchased on such date pursuant to such Terms Agreement, the non-defaulting Underwriters named in such Terms Agreement shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations under such Terms Agreement bear to the underwriting obligations of all non-defaulting Underwriters, or

(b)                                 if the aggregate principal amount of Defaulted Securities exceeds 10% of the aggregate principal amount of Underwritten Securities to be purchased pursuant to such Terms Agreement, such Terms Agreement (or, with respect to the Underwriters’ exercise of any applicable over-allotment option for the purchase of Option Underwritten Securities on a Date of Delivery after the Closing Time, the obligations of the Underwriters to purchase, and the Operating Partnership to sell, such Option Underwritten Securities on such Date of Delivery) shall terminate without liability on the part of any non-defaulting Underwriter except as provided by Section 9(c).

No action taken pursuant to this Section 10 shall relieve any defaulting Underwriter from liability in respect of its default.

In the event of any such default which does not result in (i) a termination of the applicable Terms Agreement or (ii) in the case of a Date of Delivery after the Closing Time, a termination of the obligations of the Underwriters and the Operating Partnership with respect to the related Option Underwritten Securities, as the case may be, either the Representatives or the Operating Partnership shall have the right to postpone the Closing Time or the relevant Date of Delivery, as the case may be, for a period not exceeding seven days in order to effect any required changes in the Registration Statement or the Prospectus or in any other documents or arrangements.

28

SECTION 12.                          Notices.

All notices and other communications hereunder shall be in writing and shall be deemed to have been duly given or transmitted by any standard form of telecommunication. Notices to the Underwriters shall be directed as provided in a Terms Agreement, and notices to the Operating Partnership shall be directed to it at ▇▇▇ ▇▇▇▇▇▇▇▇▇▇▇ ▇▇▇▇, ▇▇▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇ ▇▇▇▇▇, attention of ▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇, Chief Executive Officer and President.

SECTION 13.                          Parties.

This Underwriting Agreement and the applicable Terms Agreement shall each inure to the benefit of and be binding upon the parties hereto and, upon execution of such Terms Agreement, any other Underwriters and their respective successors. Nothing expressed or mentioned in this Underwriting Agreement or such Terms Agreement is intended or shall be construed to give any person, firm or corporation, other than the Underwriters, the Operating Partnership and their respective successors and the controlling persons and officers and directors 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 Underwriting Agreement or such Terms Agreement or any provision herein or therein contained. This Underwriting Agreement and such Terms Agreement and all conditions and provisions hereof and thereof are intended to be for the sole and exclusive benefit of the parties hereto and thereto and their respective successors, and said controlling persons and officers and directors and their heirs and legal representatives, and for the benefit of no other person, firm or corporation. No purchaser of Underwritten Securities from any Underwriter shall be deemed to be a successor by reason merely of such purchase.

SECTION 14.                          No Fiduciary Duty.

The Operating Partnership hereby acknowledges that (a) the purchase and sale of the Debt Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Operating Partnership, on the one hand, and the Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Operating Partnership and (c) the Operating Partnership’s engagement of the Underwriters in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Operating Partnership agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether any of the Underwriters has advised or is currently advising the Operating Partnership on related or other matters). The Operating Partnership agrees that it will not claim that the Underwriters have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Operating Partnership, in connection with such transaction or the process leading thereto.

SECTION 15.                          Integration.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Operating Partnership and the Underwriters, or any of them, with respect to the subject matter hereof.
