(d)                any settlement or compromise of any of the Guaranteed Obligations, any security therefor, or any liability of any other party with respect to any of the Guaranteed Obligations, or any subordination of the payment of any of the Guaranteed Obligations to the payment of any other liability of the Borrower or any other Loan Party;

(e)                any bankruptcy, insolvency, reorganization, composition, adjustment, dissolution, liquidation or other like proceeding relating to such Guarantor, any other Loan Party or any other Person, or any action taken with respect to this Guaranty by any trustee or receiver, or by any court, in any such proceeding;

(i)                 any defect, limitation or insufficiency in the borrowing powers of the Borrower or in the exercise thereof;

(m)              any other circumstance which might otherwise constitute a defense available to, or a discharge of, a Guarantor hereunder (other than payment and performance in full).

Section 4. Action with Respect to Guaranteed Obligations. The Guaranteed Parties may, at any time and from time to time, without the consent of, or notice to, any Guarantor, and without discharging any Guarantor from its obligations hereunder, take any and all actions described in Section 3. and may otherwise: (a) amend, modify, alter or supplement the terms of any of the Guaranteed Obligations, including, but not limited to, extending or shortening the time of payment of any of the Guaranteed Obligations or changing the interest rate that may accrue on any of the Guaranteed Obligations; (b) amend, modify, alter or supplement any Guarantied Document; (c) sell, exchange, release or otherwise deal with all, or any part, of any collateral securing any of the Guaranteed Obligations; (d) release any Loan Party or other Person liable in any manner for the payment or collection of any of the Guaranteed Obligations; (e) exercise, or refrain from exercising, any rights against any Loan Party or any other Person; and (f) apply any sum, by whomsoever paid or however realized, to the Guaranteed Obligations in such order as the Guarantied Parties shall elect.

Section 5. Representations and Warranties. Each Guarantor hereby makes to the Administrative Agent and the other Guarantied Parties all of the representations and warranties made by the Borrower with respect to or in any way relating to such Guarantor in the Credit Agreement and the other Guarantied Documents, as if the same were set forth herein in full.

Section 6. Covenants. Each Guarantor will comply with all covenants with which the Borrower is to cause such Guarantor to comply under the terms of the Credit Agreement or any of the other Guarantied Documents.

Section 7. Waiver. Each Guarantor, to the fullest extent permitted by Applicable Law, hereby waives notice of acceptance hereof or any presentment, demand, protest or notice of any kind, and any other act or thing, or omission or delay to do any other act or thing, which in any manner or to any extent might vary the risk of such Guarantor or which otherwise might operate to discharge such Guarantor from its obligations hereunder.

Section 8. Inability to Accelerate. If the Guarantied Parties or any of them are prevented under Applicable Law or otherwise from demanding or accelerating payment, upon an Event of Default, of any of the Guaranteed Obligations by reason of any automatic stay or otherwise, the Administrative Agent and/or the other Guarantied Parties shall be entitled to receive from each Guarantor, upon demand therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

Section 9. Reinstatement of Guaranteed Obligations. If claim is ever made on the Administrative Agent or any other Guarantied Party for repayment or recovery of any amount or amounts received in payment or on account of any of the Guaranteed Obligations, and the Administrative Agent or such other Guarantied Party repays all or part of said amount by reason of (a) any judgment, decree or order of any court or administrative body of competent jurisdiction, or (b) any settlement or compromise of any such claim effected by the Administrative Agent or such other Guarantied Party with any such claimant (including the Borrower or a trustee in bankruptcy for the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding on it, notwithstanding any revocation hereof or the cancellation of any of the Guarantied Documents and such Guarantor shall be and remain liable to the Administrative Agent or such other Guarantied Party for the amounts so repaid or recovered to the same extent as if such amount had never originally been paid to the Administrative Agent or such other Guarantied Party.

Section 10. Subrogation. Upon the making by any Guarantor of any payment hereunder for the account of another Loan Party, such Guarantor shall be subrogated to the rights of the payee against such Loan Party; provided, however, that such Guarantor shall not enforce any right or receive any payment by way of subrogation or otherwise take any action in respect of any other claim or cause of action such Guarantor may have against such Loan Party arising by reason of any payment or performance by such Guarantor pursuant to this Guaranty, unless and until all of the Guaranteed Obligations (other than contingent obligations not then due) have been paid and performed in full. If any amount shall be paid to such Guarantor on account of or in respect of such subrogation rights or other claims or causes of action, such Guarantor shall hold such amount in trust for the benefit of the Guarantied Parties and shall forthwith pay such amount to the Administrative Agent to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms of the Credit Agreement or to be held by the Administrative Agent as collateral security for any Guaranteed Obligations existing.

Section 11. Payments Free and Clear. All sums payable by each Guarantor hereunder, whether of principal, interest, fees, expenses, premiums or otherwise, shall be paid in full, without set-off or counterclaim or any deduction or withholding whatsoever (including any Taxes), except as required by Applicable Law, subject to the provisions of Section 3.10 of the Credit Agreement.

Section 12. Set-off. In addition to any rights now or hereafter granted under any of the other Guarantied Documents or Applicable Law and not by way of limitation of any such rights, each Guarantor hereby authorizes each Guarantied Party, each Affiliate of a Guarantied Party, and each Participant, at any time while an Event of Default exists, without any prior notice to such Guarantor or to any other Person, any such notice being hereby expressly waived, but in the case of a Guarantied Party (other than the Administrative Agent), an Affiliate of a Guarantied Party (other than the Administrative Agent), or a Participant, subject to receipt of the prior written consent of the Requisite Lenders exercised in their sole discretion, to set-off and to appropriate and to apply any and all deposits (general or special, including, but not limited to, indebtedness evidenced by certificates of deposit, whether matured or unmatured) (other than third party funds) and any other indebtedness at any time held or owing by a Guarantied Party, an Affiliate of a Guarantied Party or such Participant to or for the credit or the account of such Guarantor against and on account of any of the Guaranteed Obligations, although such obligations shall be contingent or unmatured. Each Guarantor agrees, to the fullest extent permitted by Applicable Law, that any Participant may exercise rights of setoff or counterclaim and other rights with respect to its participation as fully as if such Participant were a direct creditor of such Guarantor in the amount of such participation.

Section 13. Subordination. Each Guarantor hereby expressly covenants and agrees for the benefit of the Guarantied Parties that all obligations and liabilities of any other Loan Party to such Guarantor of whatever description, including without limitation, all intercompany receivables of such Guarantor from any other Loan Party (collectively, the “Junior Claims”) shall be subordinate and junior in right of payment to all Guaranteed Obligations. If an Event of Default shall exist, no Guarantor shall accept any direct or indirect payment (in cash, property or securities, by setoff or otherwise) from or any other Loan Party on account of or in any manner in respect of any Junior Claim until all of the Guaranteed Obligations (other than contingent obligations not then due) have been paid in full.

Section 14. Avoidance Provisions. It is the intent of each Guarantor and the Guarantied Parties that in any Proceeding, such Guarantor’s maximum obligation hereunder shall equal, but not exceed, the maximum amount which would not otherwise cause the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Guarantied Parties) to be avoidable or unenforceable against such Guarantor in such Proceeding as a result of Applicable Law, including without limitation, (a) Section 548 of the Bankruptcy Code and (b) any state fraudulent transfer or fraudulent conveyance act or statute applied in such Proceeding, whether by virtue of Section 544 of the Bankruptcy Code or otherwise. The Applicable Laws under which the possible avoidance or unenforceability of the obligations of such Guarantor hereunder (or any other obligations of such Guarantor to the Guarantied Parties) shall be determined in any such Proceeding are referred to as the “Avoidance Provisions”. Accordingly, to the extent that the obligations of any Guarantor hereunder would otherwise be subject to avoidance under the Avoidance Provisions, the maximum Guaranteed Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the Guaranteed Obligations are deemed to have been incurred under the Avoidance Provisions, would not cause the obligations of any Guarantor hereunder (or any other obligations of such Guarantor to the Guarantied Parties), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Administrative Agent and the other Guarantied Parties hereunder to the maximum extent that would not cause the obligations of any Guarantor hereunder to be subject to avoidance under the Avoidance Provisions, and no Guarantor or any other Person shall have any right or claim under this Section as against the Guarantied Parties that would not otherwise be available to such Person under the Avoidance Provisions.

Section 15. Information. Each Guarantor assumes all responsibility for being and keeping itself informed of the financial condition of the Loan Parties, and of all other circumstances bearing upon the risk of nonpayment of any of the Guaranteed Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that neither of the Administrative Agent nor any other Guarantied Party shall have any duty whatsoever to advise any Guarantor of information regarding such circumstances or risks.

Section 16. Governing Law. THIS GUARANTY SHALL BE GOVERNED BY, AND CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED, AND TO BE FULLY PERFORMED, IN SUCH STATE.

SECTION 17. WAIVER OF JURY TRIAL.

(a)                 EACH GUARANTOR, AND EACH OF THE GUARANTIED PARTIES BY ACCEPTING THE BENEFITS HEREOF, ACKNOWLEDGES THAT ANY DISPUTE OR CONTROVERSY BETWEEN OR AMONG SUCH GUARANTOR AND ANY OF THE GUARANTIED PARTIES WOULD BE BASED ON DIFFICULT AND COMPLEX ISSUES OF LAW AND FACT AND WOULD RESULT IN DELAY AND EXPENSE TO THE PARTIES. ACCORDINGLY, TO THE EXTENT PERMITTED BY APPLICABLE LAW, EACH OF THE GUARANTORS, AND THE GUARANTIED PARTIES BY ACCEPTING THE BENEFITS HEREOF, HEREBY WAIVES ITS RIGHT TO A TRIAL BY JURY IN ANY ACTION OR PROCEEDING OF ANY KIND OR NATURE IN ANY COURT OR TRIBUNAL IN WHICH AN ACTION MAY BE COMMENCED BY OR AGAINST ANY PARTY HERETO ARISING OUT OF THIS GUARANTY.

(b)                EACH GUARANTOR IRREVOCABLY AND UNCONDITIONALLY AGREES THAT IT WILL NOT COMMENCE ANY ACTION, LITIGATION OR PROCEEDING OF ANY KIND OR DESCRIPTION, WHETHER IN LAW OR EQUITY, WHETHER IN CONTRACT OR IN TORT OR OTHERWISE, AGAINST THE ADMINISTRATIVE AGENT, ANY OTHER GUARANTIED PARTY, OR ANY RELATED PARTY OF THE FOREGOING IN ANY WAY RELATING TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT OR THE TRANSACTIONS RELATING HERETO OR THERETO, IN ANY FORUM OTHER THAN THE COURTS OF THE STATE OF NEW YORK SITTING IN NEW YORK COUNTY, AND OF THE UNITED STATES DISTRICT COURT OF THE SOUTHERN DISTRICT OF NEW YORK, AND ANY APPELLATE COURT FROM ANY THEREOF, AND EACH OF THE PARTIES HERETO IRREVOCABLY AND UNCONDITIONALLY SUBMITS TO THE JURISDICTION OF SUCH COURTS AND AGREES THAT ALL CLAIMS IN RESPECT OF ANY SUCH ACTION, LITIGATION OR PROCEEDING MAY BE HEARD AND DETERMINED IN SUCH NEW YORK STATE COURT OR, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN SUCH FEDERAL COURT. EACH OF THE PARTIES HERETO AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION, LITIGATION OR PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR IN ANY OTHER MANNER PROVIDED BY LAW. NOTHING IN THIS GUARANTY OR IN ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT THE ADMINISTRATIVE AGENT OR ANY OTHER GUARANTIED PARTY MAY OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS GUARANTY OR ANY OTHER LOAN DOCUMENT AGAINST ANY GUARANTOR OR ITS PROPERTIES IN THE COURTS OF ANY JURISDICTION. EACH PARTY FURTHER WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH ACTION OR PROCEEDING IN ANY SUCH COURT OR THAT SUCH ACTION OR PROCEEDING WAS BROUGHT IN AN INCONVENIENT FORUM, AND EACH AGREES NOT TO PLEAD OR CLAIM THE SAME. THE CHOICE OF FORUM SET FORTH IN THIS SECTION SHALL NOT BE DEEMED TO PRECLUDE THE BRINGING OF ANY ACTION BY ANY GUARANTIED PARTY OR THE ENFORCEMENT BY ANY GUARANTIED PARTY OF ANY JUDGMENT OBTAINED IN SUCH FORUM IN ANY OTHER APPROPRIATE JURISDICTION.

(c)                THE PROVISIONS OF THIS SECTION HAVE BEEN CONSIDERED BY EACH PARTY WITH THE ADVICE OF COUNSEL AND WITH A FULL UNDERSTANDING OF THE LEGAL CONSEQUENCES THEREOF, AND SHALL SURVIVE THE PAYMENT OF THE LOANS AND ALL OTHER AMOUNTS PAYABLE HEREUNDER OR UNDER THE OTHER GUARANTIED DOCUMENTS, THE TERMINATION OR EXPIRATION OF ALL LETTERS OF CREDIT AND THE TERMINATION OF THIS GUARANTY.

Section 18. Loan Accounts. The Administrative Agent and each other Guarantied Party may maintain books and accounts setting forth the amounts of principal, interest and other sums paid and payable with respect to the Guaranteed Obligations arising under or in connection with the Loan Documents, and in the case of any dispute relating to any of the outstanding amount, payment or receipt of any of such Guaranteed Obligations or otherwise, the entries in such books and accounts shall be binding on the Guarantors absent manifest error. The failure of the Administrative Agent or any other Guarantied Party to maintain such books and accounts shall not in any way relieve or discharge any Guarantor of any of its obligations hereunder.

Section 19. Waiver of Remedies. No delay or failure on the part of the Administrative Agent or any other Guarantied Party in the exercise of any right or remedy it may have against any Guarantor hereunder or otherwise shall operate as a waiver thereof, and no single or partial exercise by the Administrative Agent or any other Guarantied Party of any such right or remedy shall preclude any other or further exercise thereof or the exercise of any other such right or remedy.

Section 20. Termination and Release. This Guaranty shall remain in full force and effect with respect to each Guarantor until termination of the Commitments and payment in full of the Guaranteed Obligations (other than (A) contingent indemnification obligations, (B) obligations in respect of Letters of Credit that have been Cash Collateralized or back-stopped and (C) obligations and liabilities under Specified Derivatives Contract or Specified Cash Management Agreement). At the request and sole expense of the Borrower, if any Guarantor is a Subsidiary, it shall be released from its obligations hereunder (i) in accordance with Section 8.14 of the Credit Agreement, (ii) if such Person becomes an Excluded Subsidiary as a result of a transaction permitted under the Loan Documents or (iii) such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents.

Section 21. Successors and Assigns. Each reference herein to the Administrative Agent or any other Guarantied Party shall be deemed to include such Person’s respective successors and assigns (including, but not limited to, any holder of the Guaranteed Obligations) in whose favor the provisions of this Guaranty also shall inure, and each reference herein to each Guarantor shall be deemed to include such Guarantor’s successors and assigns, upon whom this Guaranty also shall be binding. The Guarantied Parties may, in accordance with the applicable provisions of the Guarantied Documents, assign, transfer or sell any Guarantied Obligation, or grant or sell participations in any Guaranteed Obligations, to any Person without the consent of, or notice to, any Guarantor and without releasing, discharging or modifying any Guarantor’s obligations hereunder. Each Guarantor hereby consents to the delivery by the Administrative Agent and any other Guarantied Party to any Assignee or Participant (or any prospective Assignee or Participant) of any financial or other information regarding the Borrower or any Guarantor. No Guarantor may assign or transfer its obligations hereunder to any Person without the prior written consent of the Administrative Agent and any such assignment or other transfer to which all of the Lenders have not so consented shall be null and void.

Section 22. JOINT AND SEVERAL OBLIGATIONS. THE OBLIGATIONS OF THE GUARANTORS HEREUNDER SHALL BE JOINT AND SEVERAL, AND ACCORDINGLY, EACH GUARANTOR CONFIRMS THAT IT IS LIABLE FOR THE FULL AMOUNT OF THE “GUARANTEED OBLIGATIONS” AND ALL OF THE OBLIGATIONS AND LIABILITIES OF EACH OF THE OTHER GUARANTORS HEREUNDER.

Section 25. Notices. All notices, requests and other communications hereunder shall be in writing (including facsimile transmission or similar writing) and shall be given (a) to each Guarantor at its address set forth below its signature hereto, (b) to the Administrative Agent or any other Guarantied Party at its address for notices provided for in the Guarantied Documents, as applicable, or (c) as to each such party at such other address as such party shall designate in a written notice to the other parties. Each such notice, request or other communication shall be effective (i) if mailed, upon the first to occur of receipt or the expiration of 3 days after the deposit in the United States Postal Service mail, postage prepaid and addressed to the address of a Guarantor or Guarantied Party at the addresses specified; (ii) if telecopied, when transmitted; or (iii) if hand delivered or sent by overnight courier, when delivered; provided, however, that in the case of the immediately preceding clauses (i) through (iii), non-receipt of any communication as the result of any change of address of which the sending party was not notified or as the result of a refusal to accept delivery shall be deemed receipt of such communication.

Section 26. Severability. In case any provision of this Guaranty shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 27. Headings. Section headings used in this Guaranty are for convenience only and shall not affect the construction of this Guaranty.

Section 28. Limitation of Liability. None of the Administrative Agent, any other Guarantied Party or any of their respective Related Parties shall have any liability with respect to, and each Guarantor hereby waives, releases, and agrees not to sue any of them upon, any claim for any special, indirect, incidental, or consequential damages suffered or incurred by a Guarantor in connection with, arising out of, or in any way related to, this Guaranty, any of the other Guarantied Documents, or any of the transactions contemplated by this Guaranty or any of the other Guarantied Documents. Each Guarantor hereby waives, releases, and agrees not to sue the Administrative Agent, any other Guarantied Party or any of their respective Related Parties for punitive damages in respect of any claim in connection with, arising out of, or in any way related to, this Guaranty, any of the other Guarantied Documents, or any of the transactions contemplated by thereby.

Section 29. Electronic Delivery of Certain Information. Each Guarantor acknowledges and agrees that information regarding the Guarantor may be delivered electronically pursuant to Section 9.5. of the Credit Agreement.

Section 30. Right of Contribution. The Guarantors (other than REIT) hereby agree as among themselves that, if any Guarantor shall make an Excess Payment, such Guarantor shall have a right of contribution from each other Guarantor in an amount equal to such other Guarantor’s Contribution Share of such Excess Payment. The payment obligations of any Guarantor under this Section shall be subordinate and subject in right of payment to the Guaranteed Obligations until such time as the Guaranteed Obligations (other than contingent obligations not then due) have been paid and performed in full and the Commitments have expired or terminated, and none of the Guarantors shall exercise any right or remedy under this Section against any other Guarantor until such Guaranteed Obligations (other than contingent obligations not then due) have been paid and performed in full and the Commitments have expired or terminated. Subject to Section 10 of this Guaranty, this Section shall not be deemed to affect any right of subrogation, indemnity, reimbursement or contribution that any Guarantor may have under Applicable Law against any other Loan Party in respect of any payment of Guaranteed Obligations. Notwithstanding the foregoing, all rights of contribution against any Guarantor shall terminate from and after such time, if ever, that such Guarantor shall cease to be a Guarantor in accordance with the applicable provisions of the Loan Documents.

Section 31. Keepwell. Each Qualified ECP Guarantor hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under this Guaranty in respect of Swap Obligations (provided, however, that each Qualified ECP Guarantor shall only be liable under this Section for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section, or otherwise under this Guaranty, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). The obligations of each Qualified ECP Guarantor under this Section shall remain in full force and effect until termination of this Guaranty in accordance with Section 20 hereof. Each Qualified ECP Guarantor intends that this Section constitute, and this Section shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.
