WHEREAS, Guarantor acknowledges that it will receive direct and indirect benefits from the Administrative Agent and the Lenders making such financial accommodations available to the Borrower under the Bridge Credit Agreement and, accordingly, Guarantor is willing to guarantee the Borrower’s obligations to the Administrative Agent and the Lenders on the terms and conditions contained herein; and

WHEREAS, Guarantor’s execution and delivery of this Guaranty is one of the conditions precedent to the Administrative Agent and the Lenders making, or continuing to make, such financial accommodations to the Borrower.

Section 7. Waiver. 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 Loan. If the Administrative Agent and/or the Lenders are prevented from demanding or accelerating payment thereof by reason of any automatic stay or otherwise, the Administrative Agent and/or the Lenders shall be entitled to receive from Guarantor, upon demand therefor, the sums which otherwise would have been due had such demand or acceleration occurred.

Section 9. Reinstatement of Obligations. Guarantor agrees that this Guaranty shall continue to be effective or be reinstated, as the case may be, with respect to any Obligations if at any time payment of any such Obligations is rescinded or otherwise must be restored by the Administrative Agent and/or the Lenders upon the bankruptcy or reorganization of the Borrower or any Guarantor or otherwise.

Section 10. Subrogation. Until all of the Obligations shall have been indefeasibly paid in full, any right of subrogation a Guarantor may have shall be subordinate to the rights of Administrative Agent and the Lenders and Guarantor hereby waives any right to enforce any remedy which the Administrative Agent and/or the Lenders now have or may hereafter have against the Borrower, and Guarantor hereby waives any benefit of, and any right to participate in, any security or collateral given to the Administrative Agent and the Lenders to secure payment or performance of any of the Obligations.

Section 11. Payments Free and Clear. All sums payable by Guarantor hereunder shall be made free and clear of and without deduction for any Indemnified Taxes (as defined in the Bridge Credit Agreement) or Other Taxes (as defined in the Bridge Credit Agreement); provided that if any Guarantor shall be required to deduct any Indemnified Taxes or Other Taxes from such payments, then (i) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section), the Administrative Agent or any Lender (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made; (ii) such Guarantor shall make such deductions; and (iii) such Guarantor shall pay the full amount deducted to the relevant Governmental Authority (as defined in the Bridge Credit Agreement) in accordance with applicable law.

Section 12. Set-off. Guarantor hereby grants to Administrative Agent, on behalf of the Lenders, a security interest in and lien on all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by Administrative Agent to or for the credit or the account of any Guarantor. In addition to any rights now or hereafter granted under applicable law and not by way of limitation of any such rights, each Lender is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final but excluding any funds held by the Borrower on behalf of tenants or held by affiliates of Borrower or Guarantor on behalf of third parties) at any time held and other obligations at any

4

time owing by such Lender to or for the credit or the account of any Guarantor against any of and all the obligations of such Guarantor now or hereafter existing under this Guaranty held by such Lender then due and payable. Guarantor agrees, to the fullest extent it may effectively do so under applicable law, that any holder of a participation in a Note, whether or not acquired pursuant to the applicable provisions of the Bridge Credit Agreement, may exercise rights of setoff or counterclaim and other rights with respect to such participation as fully as if such holder of a participation were a direct creditor of such Guarantor in the amount of such participation.

Section 13. Subordination. Guarantor hereby expressly covenants and agrees for the benefit of the Administrative Agent and the Lenders that all obligations and liabilities of the Borrower or any other Guarantor to such Guarantor of whatever description, including without limitation, all intercompany receivables of such Guarantor from the Borrower or any other Guarantor (collectively, the “Junior Claims”) shall be subordinate and junior in right of payment to all Obligations; provided, however, that payment thereof may be made so long as no Event of Default shall have occurred and be continuing. If an Event of Default shall have occurred and be continuing, then no Guarantor shall accept any direct or indirect payment (in cash, property, securities by setoff or otherwise) from the Borrower or any other Guarantor on account of or in any manner in respect of any Junior Claim until all of the Obligations have been indefeasibly paid in full.

Section 14. Avoidance Provisions. It is the intent of Guarantor, the Administrative Agent and the Lenders 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 Administrative Agent and the Lenders) 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 of 1978, as amended (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 Administrative Agent and the Lenders) 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 Obligations for which such Guarantor shall be liable hereunder shall be reduced to that amount which, as of the time any of the 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 Administrative Agent and the Lenders), to be subject to avoidance under the Avoidance Provisions. This Section is intended solely to preserve the rights of the Administrative Agent and the Lenders 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 nor any other Person shall have any right or claim under this Section as against the Administrative Agent and the Lenders that would not otherwise be available to such Person under the Avoidance Provisions.

Section 15. Information. Guarantor assumes all responsibility for being and keeping itself informed of the financial condition of the Borrower, of the other Guarantors and of all

5

other circumstances bearing upon the risk of nonpayment of any of the Obligations and the nature, scope and extent of the risks that such Guarantor assumes and incurs hereunder, and agrees that none of the Administrative Agent or any Lender shall have any duty whatsoever to advise any Guarantor of information regarding such circumstances or risks.
