(z)            Each of the Co-Obligors, their Subsidiaries and the Joint Venture Entities owns or possesses adequate rights to use all material patents, patent applications, trademarks, service marks, trade names, trademark registrations, service mark registrations, copyrights and licenses necessary for the conduct of its business and has no reason to believe that the conduct of its business will conflict with, and has not received any notice of any claim of conflict with, any such rights of others.

(aa)         Except as described in the Registration Statement, the Time of Sale Information and the Prospectus, there are no actions, suits or proceedings by or before any court or Governmental Authority pending to which any of the Co-Obligors, their Subsidiaries or any Joint Venture Entity is a party or of which any of the Properties or assets of any of the Co-Obligors, Subsidiaries or Joint Venture Entities is the subject which, if determined adversely to such entities, might have a Material Adverse Effect, and to the knowledge of any of the Co-

8

Obligors, no such proceedings are threatened or contemplated by court or Governmental Authority or threatened by others.

(bb)         There are no contracts or other documents which are required to be described in the Registration Statement, the Time of Sale Information and the Prospectus, which have not been disclosed in the Registration Statement, the Time of Sale Information and the Prospectus or incorporated therein by reference.

(cc)         No relationship, direct or indirect, exists between or among any of the Co-Obligors, their Subsidiaries or any Joint Venture Entity on the one hand, and the directors, officers, stockholders, customers or suppliers of the Co-Obligors, their Subsidiaries or any Joint Venture Entity on the other hand, which would be required by the Securities Act to be described (other than as disclosed in the Registration Statement, the Time of Sale Information or the Prospectus).

(dd)         No labor disturbance by the employees of any Co-Obligor, their Subsidiaries or any Joint Venture Entity exists or, to the knowledge of the Co-Obligors, is imminent in either case which might have a Material Adverse Effect.

At all times since their respective formations, each of SLG OP, Wyoming and Reckson OP has been classified for taxation under the Code as either (1) a partnership and not as (a) an association taxable as a corporation or (b) a “publicly traded partnership” taxable as a corporation under Section 7704(a) of the Code or (2) in the case of Wyoming, and Reckson OP, only, as an entity disregarded as an entity separate from SLG OP for U.S. federal income tax purposes under Treasury Regulation Section  ###-###-####-3, and no actions have been taken or will be taken (or not taken which are required to be taken) which would cause such qualification or classification to be lost.

(hh)         Since the date as of which information is given in the Registration Statement or the Time of Sale Information through the date hereof, and except as may otherwise be disclosed in, or contemplated by, the Registration Statement, the Time of Sale Information and the Prospectus,  no Co-Obligor has (a) issued or granted any securities, other than with respect to grants of securities pursuant to (i) Equity Plans (as hereinafter defined), (ii) the Contribution Agreement and related Registration Rights Agreement, each dated October 25, 2010, among Devash LLC, Eretz LLC, SLG OP and the Company (the “Eretz Agreements”) and (iii) the 747 Madison Agreement, (b) incurred any liability or obligation, direct or contingent, other than liabilities and obligations which were incurred in the ordinary course of business, (c) entered into any transaction not in the ordinary course of business or (d) except for regular quarterly dividends on the Company’s common stock, par value $0.01 per share (“Common Shares”) and preferred stock, and regular distributions on the Units, declared or paid any dividend or distribution on its capital stock, Units or other form of ownership interests.

(ll)           None of the Co-Obligors, their Subsidiaries or any Joint Venture Entity, nor any director, officer, agent, employee or other person associated with or acting on behalf of such entity, has (A) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity, (B) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds, (C) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977, or (D) made any bribe, rebate, payoff, influence payment, kickback or other unlawful payment.

(nn)         Other than this Agreement and as set forth in the Registration Statement, the Time of Sale Information and the Prospectus under the heading “Underwriting,” there are no contracts, agreements or understandings between any Co-Obligor nor any of their subsidiaries and any person that would give rise to a valid claim against any Co-Obligor or the Underwriters for a brokerage commission, finder’s fee or other like payment with respect to the consummation of the transactions contemplated by this Agreement.

(oo)         Except as disclosed in the Time of Sale Information and the Prospectus, there are no contracts, agreements or understandings between the Company and any person granting such person the right to require the Company to include any securities in the Prospectus Supplement.

(pp)         The Co-Obligors intend to apply the net proceeds from the sale of the Notes in accordance with the description set forth in the Time of Sale Information and the Prospectus under the caption “Use of Proceeds.”

(qq)         Each of the Co-Obligors, their Subsidiaries and the Joint Venture Entities possess such permits, certificates, franchises, licenses, approvals, consents and other authorizations (collectively, “Governmental Licenses”) issued by the appropriate federal, state, local or foreign regulatory agencies or bodies necessary to the

10

ownership of the Properties or any of its other properties or assets or to conduct the business now operated by them except where failure to possess any such Governmental Licenses would not result in a Material Adverse Effect; the Co-Obligors, their Subsidiaries and the Joint Venture Entities 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 when 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; and none of the Co-Obligors, their Subsidiaries or the Joint Venture Entities 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.

(rr)           None of the Co-Obligors, nor any of their respective trustees, directors, officers, members or controlling persons, has taken or will take, directly or indirectly, any action resulting in a violation of Regulation M under the Exchange 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 Company to facilitate the sale or resale of the Notes.

(ss)         Each of the Co-Obligors has established and maintains disclosure controls and procedures (as such term is defined in Rule 13a-15 under the Exchange Act), which (i) are designed to ensure that (A) the material information relating to such Co-Obligor, as applicable, including its consolidated subsidiaries, is made known to each of such Co-Obligor’s, as applicable, principal executive officer and principal financial officer by others within those entities, particularly during the preparation of the Registration Statement, the Time of Sale Information and the Prospectus and (B) the information required to be disclosed by such Co-Obligor, as applicable, in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Commission’s rules and forms; (ii) have been evaluated for effectiveness as of the date hereof; and (iii) are effective in all material respects to perform the functions for which they were established.

(tt)           Based on its evaluation of its internal control over financial reporting, the Company is not aware of (i) any significant deficiency or material weakness in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the Company’s ability to record, process, summarize and report financial information; or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in the Company’s internal control over financial reporting.  Subject to the foregoing, there have been no significant changes in internal control over financial reporting or in other factors that could significantly affect the Company’s internal control over financial reporting, including any corrective actions with regard to significant deficiencies and material weaknesses since the end of the Company’s most recent audited fiscal year.

(uu)         Based on its evaluation of its internal control over financial reporting, Reckson OP is not aware of (i) any significant deficiency or material weakness in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect Reckson OP’s ability to record, process, summarize and report financial information; or (ii) any fraud, whether or not material, that involves management or other employees who have a significant role in Reckson OP’s internal control over financial reporting.  There have been no significant changes in internal control over financial reporting or in other factors that could significantly affect internal control over Reckson OP’s financial reporting, including any corrective actions with regard to significant deficiencies and material weaknesses since the end of Reckson OP’s most recent audited fiscal year.

2.             Purchase and Sale of the Notes.  On the basis of the representations and warranties contained in, and subject to the terms and conditions of, this Agreement, the Co-Obligors agree to sell to each Underwriter and each Underwriter, severally and not jointly, agrees to purchase from the Co-Obligors, the aggregate principal amount of the Notes set forth opposite their names in Schedule 1 hereto, at a purchase price equal to 98.817% of the principal amount thereof.

(b)           The Co-Obligors understand that the Underwriters intend to make a public offering of the Notes as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Notes on the terms set forth in the Time of Sale Information. The Co-Obligors acknowledge and agree that the Underwriters may offer and sell the Notes to or through any affiliate of an Underwriter and that any such affiliate may offer and sell the Notes purchased by it to or through any Underwriter.

(c)           Delivery of and payment for the Notes shall be made at the office of Skadden, Arps, Slate, Meagher & Flom LLP, Four Times Square, New York, New York 10036, at 9:00 A.M., local time, on August 5, 2011, or at such other date or place as shall be determined by agreement between the Representatives and the Co-Obligors. This date and time are sometimes referred to herein as the “Closing Date.”  On the Closing Date, the Co-Obligors shall deliver or cause to be delivered certificates representing the Notes to the Representatives against payment of the purchase price by wire transfer of same-day funds.  The certificates for the Notes shall be in such denominations and registered in the name of Cede & Co., as nominee of the Depositary, pursuant to the DTC Agreement, and shall be made available for inspection not less than one full business day prior to the Closing Date at a location in New York, New York as the Representatives may designate.  Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of the Underwriters hereunder.

It is understood that each Underwriter has authorized the Representatives, for its account, to accept delivery of, receipt for, and make payment of the purchase price for, the Notes it has agreed to purchase.  Wells Fargo Securities, LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Morgan Stanley & Co. LLC individually and not as representatives of the Underwriters, may (but shall not be obligated to) make payment of the purchase price for the Notes, to be purchased by any Underwriter whose funds have not been received by the Closing Date, but such payment shall not relieve such Underwriter from its obligations hereunder.

3.             Further Agreements of the Co-Obligors.  Each of the Co-Obligors hereby agrees, jointly and severally, that:

(a)           The Company will file the final Prospectus with the Commission within the time periods specified by Rule 424(b) and Rule 430A, 430B or 430C under the Securities Act, will file any Issuer Free Writing Prospectus (including the Term Sheet in the form of Annex C hereto) to the extent required by Rule 433 under the Securities Act; and will file promptly all reports and any definitive proxy or information statements required to be filed by the Company with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act subsequent to the date of the Prospectus Supplement and for so long as the delivery of a prospectus is required in connection with the offering or sale of the Notes; and the Company will furnish copies of the Prospectus and each Issuer Free Writing Prospectus (to the extent not previously delivered) to the Representatives in New York City prior to 10:00 A.M., New York City time, on the business day next succeeding the date of this Agreement in such quantities as the Representative may reasonably request.

(b)           The Company will pay the registration fees for this offering within the time period required by Rule 456(b)(1)(i) under the Securities Act (without giving effect to the proviso therein) and in any event prior to the Closing Date.

(c)           Before making, preparing, using, authorizing, approving or distributing any Issuer Free Writing Prospectus, the Co-Obligors will furnish to the Underwriters and counsel to the Underwriters a copy of the proposed Issuer Free Writing Prospectus for review and will not make, prepare, use, authorize, approve or distribute any such Issuer Free Writing Prospectus to which the Underwriters reasonably object. Without the prior written consent of the

12

Underwriters, none of the Co-Obligors have given, and none of the Co-Obligors will give, to any prospective purchaser of the Notes any written information concerning the offering of the Notes other than materials contained in, or incorporated by reference into, the Registration Statement, the Time of Sale Information, or Prospectus or any other offering materials prepared by or with the prior written consent of the Representatives.

(d)           The Co-Obligors will furnish to each of the Representatives and to counsel for the Underwriters, without charge, (A) a conformed copy of the Registration Statement as originally filed and each amendment thereto, in each case including all exhibits and consents filed therewith and (B) during the Prospectus Delivery Period (as defined below), as many copies of the Prospectus (including all amendments and supplements thereto and documents incorporated by reference therein) and each Issuer Free Writing Prospectus as the Representatives may reasonably request. As used herein, the term “Prospectus Delivery Period” means such period of time after the first date of the public offering of the Notes as in the opinion of counsel for the Underwriters a prospectus relating to the Notes is required by law to be delivered (or required to be delivered but for Rule 172 under the Securities Act) in connection with sales of the Notes by any Underwriter or dealer.

(e)           The Co-Obligors will not amend or supplement the Registration Statement, the Time of Sale Information or the Prospectus, other than by filing documents under the Exchange Act that are incorporated by reference therein, without the prior written consent of the Representatives, such consent not to be unreasonably withheld or delayed; provided, however, that prior to the completion of the distribution of the Notes by the Underwriters (as determined by the Representatives), the Co-Obligors will not file any document under the Exchange Act that is incorporated by reference in the Registration Statement, the Time of Sale Information or the Prospectus unless, prior to such proposed filing, the Co-Obligors have furnished each Representative with a copy of such document for their review and each Representative has not reasonably objected to the filing of such document.  The Co-Obligors will promptly advise the Representatives when any document filed under the Exchange Act that is incorporated by reference in the Registration Statement, the Time of Sale Information or the Prospectus shall have been filed with the Commission.

(f)           During the Prospectus Delivery Period, the Company will advise the Representatives promptly, and confirm such advice in writing, (i) when any amendment to the Registration Statement has been filed or becomes effective; (ii) when any supplement to the Prospectus or any amendment to the Prospectus or any Issuer Free Writing Prospectus has been filed; (iii) of any request by the Commission for any amendment to the Registration Statement or any amendment or supplement to the Prospectus or the receipt of any comments from the Commission relating to the Registration Statement or any other request by the Commission for any additional information; (iv) of the issuance by the Commission of any order suspending the effectiveness of the Registration Statement or preventing or suspending the use of any Preliminary Prospectus or the Prospectus or the initiation or threatening of any proceeding for that purpose or pursuant to Section 8A of the Securities Act; (v) of the occurrence of any event within the Prospectus Delivery Period as a result of which the Prospectus, the Time of Sale Information or any Issuer Free Writing Prospectus as then amended or supplemented would include any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances existing when the Prospectus, the Time of Sale Information or any such Issuer Free Writing Prospectus is delivered to a purchaser, not misleading; (vi) of the receipt by the Company of any notice of objection of the Commission to the use of any post-effective amendment to the Registration Statement pursuant to Rule 401(g)(2) under the Securities Act; and (vii) of the receipt by the Company of any notice with respect to any suspension of the qualification of the Notes for offer and sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and the Company will use its reasonable best efforts to prevent the issuance of any such order suspending the effectiveness of the Registration Statement, preventing or suspending the use of any Preliminary Prospectus or the Prospectus or suspending any such qualification of the Notes and, if any such order is issued, will obtain as soon as possible the withdrawal thereof.

(g)           If at any time prior to the completion of the sale of the Notes by each Underwriter (as determined by the Representatives), any event occurs as a result of which the Registration Statement, the Time of Sale Information or the Prospectus, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it should be necessary to amend or supplement the Registration Statement, the Time of Sale Information or the Prospectus to comply with applicable law, the Co-Obligors will promptly (i) notify the Underwriters of any such event so that any use of the Registration Statement, the Time of Sale Information or the Prospectus may cease until it is amended or supplemented; (ii) subject to the requirements of Section 3(c), prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any supplemented or amended the Registration Statement, the Time of Sale Information

13

or the Prospectus to each Underwriter and counsel for the Underwriters without charge in such quantities as they may reasonably request.

(h)           The Co-Obligors will arrange, if necessary, for the qualification of the Notes for sale by the Underwriters under the laws of such jurisdictions as the Representatives may designate and will maintain such qualifications in effect so long as required for the sale of the Notes; provided that in no event shall any Co-Obligor be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Notes, in any jurisdiction where it is not now so subject.  A Co-Obligor will promptly advise the Representatives of the receipt by a Co-Obligor of any notification with respect to the suspension of the qualification of the Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(i)            The Company will make generally available to its security holders and the Underwriters as soon as reasonably practicable an earning statement that satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 of the Commission promulgated thereunder covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the “effective date” (as defined in Rule 158) of the Registration Statement.

(j)            Each of the Co-Obligors will cooperate with the Representatives and use its best efforts to permit the Notes to be eligible for clearance and settlement through the Depositary.

(k)           The Co-Obligors will comply with all applicable securities and other laws, rules and regulations, including, without limitation, the Sarbanes-Oxley Act, and use their best efforts to cause their directors and officers, in their capacities as such, to comply with such laws, rules and regulations, including, without limitation, the provisions of the Sarbanes-Oxley Act.

(l)            The Co-Obligors will prepare a final term sheet, containing solely a description of the Notes and the offering thereof, in the form approved by you and attached as Schedule II hereto.

(m)          For a period of five years following the Closing Date, the relevant Co-Obligors will furnish to the Representatives, upon request, copies of all materials furnished by Reckson OP and SLG OP to their respective partners or by the Company to its stockholders and all public reports and all reports and financial statements furnished by Reckson OP, SLG OP or the Company to the principal national securities exchange upon which the Notes may be listed pursuant to requirements of or agreements with such exchange or to the Commission pursuant to the Exchange Act or any rule or regulation of the Commission thereunder, unless filed with the Commission and publicly available on EDGAR.

(n)           To take such steps as shall be necessary to ensure that none of the Co-Obligors shall become an “investment company” within the meaning of such term under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder.

(o)           The Company will use its best efforts to continue to meet the requirements to qualify as a REIT under the Code.

(p)           Except for the authorization of actions permitted to be taken by the Representatives as contemplated herein or in the Registration Statement, the Time of Sale Information or the Prospectus, none of the Co-Obligors will (a) take, directly or indirectly, any action designed to cause or to result in, or that might reasonably be expected to constitute, the stabilization or manipulation of the price of any security of the Co-Obligors to facilitate the sale or resale of the Notes, and (b) until the Closing Date, (i) sell, bid for or purchase the Notes or pay any person any compensation for soliciting purchases of the Notes or (ii) pay or agree to pay to any person any compensation for soliciting another to purchase any other securities of the Co-Obligors, except, in the case of clause (ii), pursuant to the At-the-Market Equity Offering Sales Agreement, dated July 27, 2011, between the Company, SLG OP and Citigroup Global Markets Inc. and the At-the-Market Equity Offering Sales Agreement, dated July 27, 2011, between the Company, SLG OP and J.P. Morgan Securities LLC.

(q)           Prior to the Closing Date, the Co-Obligors will not, without the prior written consent of each of the Representatives (which consent may be withheld at the sole discretion of each Representative), directly or

14

(a)           It has not used, authorized use of, referred to or participated in the planning for use of, and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus”, as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Co-Obligors and not incorporated by reference into the Registration Statement and any press release issued by the Co-Obligors) other than (i) a free writing prospectus that, solely as a result of use by such underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Annex A or prepared pursuant to Section 1(c) or Section 3(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such underwriter and approved by the Co-Obligors in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”).

8.             Indemnification and Contribution.

(a)           The Co-Obligors, jointly and severally, will indemnify and hold harmless each Underwriter against any losses, claims, damages or liabilities, joint or several, to which such Underwriter may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as amended or supplemented or any amendment or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, not misleading, or (ii) an untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Information, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus as amended or supplemented or any amendment or supplement thereto, or the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading; and will reimburse such Underwriter for any legal or other expenses reasonably incurred by such Underwriter in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that none of the Co-Obligors shall be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any Registration Statement, the Time of Sale Information, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus as amended or supplemented or any such amendment or supplement, in reliance upon and in conformity with written information furnished to the Co-Obligors by the Representatives expressly for use therein, which information is set forth in Exhibit A hereto.

(b)           Each Underwriter severally, and not jointly, will indemnify and hold harmless each of the Co-Obligors against any losses, claims, damages or liabilities to which such Co-Obligor may become subject, under the Securities Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, as amended or supplemented, or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, or (ii) an untrue statement or alleged untrue statement of a material fact contained in the Time of Sale Information, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus as amended or supplemented or any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they are made, not misleading in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Time of Sale Information, any Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus as amended or supplemented, or any such amendment or supplement in reliance upon and in conformity with written information furnished to such Co-Obligor by the Representatives expressly for use therein, which information is set forth in Exhibit A hereto; and severally, and not jointly, will reimburse the Co-Obligors for any legal or other expenses reasonably incurred by the Co-Obligors in connection with investigating or defending any such action or claim as such expenses are incurred.

(c)           Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against an

18

indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify such indemnifying party shall not relieve it from any liability which it may have to any indemnified party under such subsection except to the extent it has been materially prejudiced by such failure.  In case any such action shall be brought against any indemnified party and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and, after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses, in each case subsequently incurred by such indemnified party, in connection with the defense thereof other than reasonable costs of investigation.  Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party.  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 judgment (i) includes an unconditional release of the indemnified party from all liability arising out of such action or claim and (ii) does not include any statement as to, or an admission of, fault, culpability or a failure to act, by or on behalf of any indemnified party.

(d)           If the indemnification provided for in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party in respect of such losses, claims, damages or liabilities (or actions in respect thereto), contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Co-Obligors on the one hand and the Underwriters on the other from the offering of the Notes to which such loss, claim, damage or liability (or action in respect thereof) relates.  If, however, the allocation provided by the immediately preceding sentence is not permitted by applicable law, 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 but also the relative fault of the Co-Obligors 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 benefits received by the Co-Obligors on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Co-Obligors bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth on in the table on the cover of the Prospectus.  The relative fault shall be determined by reference, 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 Co-Obligors on the one hand or the Underwriters on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Co-Obligors and the Underwriters agree that it would not be just and equitable if contributions pursuant to this subsection (d) 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 subsection (d).  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 subsection (d) 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 subsection (d), the Underwriters shall not be required to contribute any amount in excess of the amount by which the total price at which the applicable Notes 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.  No person guilty of

19

fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The indemnifying party shall not be required to indemnify the indemnified party for any amount paid or payable by the indemnified party in the settlement of any action, proceeding or investigation without the written consent of the indemnifying party, which consent shall not be unreasonably withheld, but if settled with such consent, the indemnifying party agrees to indemnify the indemnified party against any loss, claim, damage, liability or expense by reason of such settlement.  Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by Section 8 hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement.

(e)           The obligations of the Co-Obligors under this Section 8 shall be in addition to any liability which the Co-Obligors may otherwise have and shall extend, upon the same terms and conditions, to each person, if any, who controls each Underwriter within the meaning of the Securities Act; and the obligations of each Underwriter under this Section 8 shall be in addition to any liability which such Underwriter may otherwise have and shall extend, upon the same terms and conditions, to each officer and director of the Co-Obligors and to each person, if any, who controls the Co-Obligors within the meaning of the Securities Act.

9.             Termination.  The obligations of the Underwriters hereunder may be terminated by notice from the Underwriters given to and received by the Company prior to delivery of and payment for the Notes if, prior to that time, any of the following events shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement:

(a) (i) Any of the Co-Obligors or any Property shall have sustained, since the date of the latest financial statements included in the Registration Statement, the Prospectus and any Issuer Free Writing Prospectus, any loss or interference with its business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree, otherwise than as set forth or contemplated in the Prospectus or (ii) since the date of the latest financial statements included or incorporated by reference in the Registration Statement, the Time of Sale Information and the Prospectus there shall have been any change in the capital stock or long-term debt of any Co-Obligor or any change, or any development involving a prospective change, in or affecting any Property or the general affairs, management, financial position, stockholders’ equity or results of operations of any Co-Obligor, otherwise than as set forth or contemplated in the Registration Statement, the Time of Sale Information and the Prospectus, the effect of which, in any such case described in clause (i) or (ii), is, in the judgment of the Representatives, so material and adverse as to make it impracticable or inadvisable to proceed with the offering or the delivery of the Notes being delivered on the Closing Date on the terms and in the manner contemplated in the Registration Statement, the Time of Sale Information and the Prospectus;

(b)           Subsequent to the execution and delivery of this Agreement there shall have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange or the American Stock Exchange or in the over-the-counter market, or trading in any securities of the Company on any exchange or in the over-the-counter market, shall have been suspended or minimum or maximum prices shall have been established on any such exchange or such market by the Commission, FINRA or such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) a banking moratorium shall have been declared by Federal or New York state authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States has occurred, (iii) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States, or (iv) there shall have occurred any other calamity or crisis or any change or development involving a prospective substantial change in general economic, political or financial conditions (or the effect of international conditions on the financial markets in the United States shall be such) as to make it, in the sole judgment of the Representatives impracticable or inadvisable to proceed with the offering or the delivery of the Notes being delivered on the Closing Date on the terms and in the manner contemplated in the Registration Statement, the Time of Sale Information and the Prospectus; or

(c)           The Co-Obligors shall have failed at or prior to the Closing Date to have performed or complied with any of their agreements herein contained and required to be performed or complied with by them hereunder at or prior to the Closing Date.

20

10.           Reimbursement of Underwriters’ Expenses. If (a) the Co-Obligors shall fail to tender the Notes for delivery to the Representatives by reason of any failure, refusal or inability on the part of the Co-Obligors to perform any agreement on their part to be performed, or because any condition specified in Sections 5, 9(a) or (c) hereof required to be fulfilled by the Co-Obligors is not fulfilled, the Co-Obligors will reimburse the Representatives for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) incurred by the Representatives in connection with this Agreement and the proposed purchase of the Notes, and upon demand the Co-Obligors shall pay the full amount thereof to the Representatives.

11.           No Fiduciary Obligation.  The Co-Obligors acknowledge and agree that in connection with this offering, sale of the Notes or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters:  (i) no fiduciary or agency relationship between the Co-Obligors and any other person, on the one hand, and the Underwriters, on the other, exists with respect to the offering of the Notes or the transactions contemplated by this Agreement; (ii) the Underwriters are not acting as advisor, expert or otherwise, to the Co-Obligors including, without limitation, with respect to the determination of the offering price of the Notes, and such relationship between the Co-Obligors, on the one hand, and the Underwriters, on the other with respect to the offering of the Notes or the transactions contemplated by this Agreement, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Co-Obligors shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and its affiliates may have interests that differ from those of the Co-Obligors.  The Co-Obligors hereby waive any claims that the Co-Obligors may have against the Underwriters with respect to any breach of fiduciary duty in connection with the offering of the Notes or the transactions contemplated by this Agreement.

12.           Research Analyst Independence. The Co-Obligors acknowledge that the Underwriters’ research analysts and research departments are required to be independent from its investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Co-Obligors and/or the offering of the Notes that differ from the views of their investment banking divisions.  The Co-Obligors hereby waive and release, to the fullest extent permitted by law, any claims that the Co-Obligors may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Co-Obligors by such Underwriters’ investment banking divisions.  The Co-Obligors acknowledge that each Underwriter is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies which may be the subject of the transactions contemplated by this Agreement.

13.  Default by One or More of the Underwriters.  If one or more of the Underwriters shall fail at the Closing Date to purchase the Notes which it or they are obligated to purchase under this Agreement (the “Defaulted Notes”), the Representatives shall have the right, within 36 hours thereafter, to make arrangements for one or more of the non-defaulting Underwriters, to purchase all, but not less than all, of the Defaulted Notes 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 36-hour period, then:

(i)            if the number of Defaulted Notes does not exceed 10% of the number of Notes to be purchased on such date, each of the non-defaulting Underwriters shall be obligated, severally and not jointly, to purchase the full amount thereof in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Underwriters, or

(ii)           if the number of Defaulted Notes exceeds 10% of the number of Notes to be purchased on such date, this Agreement, the obligation of the Underwriters to purchase shall terminate without liability on the part of any non-defaulting Underwriters.

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

In the event of any such default which does not result in a termination of this Agreement, which does not result in a termination of the obligation of the Underwriters to purchase, either the Underwriters or the Co-Obligors shall have the right to postpone Closing Date for a period not exceeding seven days in order to effect any required

21

changes in the Registration Statement, the Time of Sale Information or the Prospectus, or in any other documents or arrangements.
