ARTICLE II

Guarantee

SECTION 2.01.     Guarantee . Each Guarantor unconditionally guarantees, jointly with the other Guarantors and severally, as a primary obligor and not merely as a surety, the due and punctual payment in full when due and performance of the Obligations. Each of the Guarantors further agrees that the Obligations may be extended or renewed, in whole or in part, without notice to or further assent from it, and that it will remain bound upon its guarantee notwithstanding any extension or renewal of any Obligation. Each of the Guarantors waives diligence, presentment to, demand of payment from and protest to the Borrowers or any other Loan Party of any of the Obligations, and also waives notice of acceptance of its guarantee and notice of protest for nonpayment and any requirement that the Administrative Agent or any Guaranteed Party exhaust any right, power or remedy or proceed against any Person under any of the Loan Documents or any other documents relating to the Obligations or any other agreement or instrument referred to therein, or against any other Person under any other guarantee of, or security for, any of the Obligations.

SECTION 2.02.     Guarantee of Payment . (a) Each of the Guarantors further agrees that its guarantee hereunder constitutes a continuing guarantee of payment in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) strictly in accordance with the terms thereof and not of collection, and waives any right to require that any resort be had by the Administrative Agent or any other Guaranteed Party to any security held for the payment of the Obligations or to any balance of any deposit account or credit on the books of the Administrative Agent or any other Guaranteed Party in favor of the Borrowers or any other Person. The Guarantors hereby further agree that if any of the Obligations are not paid in full when due (whether at stated maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise), the Guarantors will, jointly and severally, promptly pay the same, without any demand or notice whatsoever, and that in the case of any extension of time of payment or renewal of any of the Obligations, the

2

same will be promptly paid in full when due (whether at extended maturity, as a mandatory prepayment, by acceleration, as a mandatory cash collateralization or otherwise) in accordance with the terms of such extension or renewal.

(b)            Notwithstanding any provision to the contrary contained herein, in any other of the Loan Documents, Swap Agreements or other documents relating to the Obligations, the obligations of each Guarantor under this Agreement and the other Loan Documents shall be limited to an aggregate amount equal to the largest amount that would not render such obligations subject to avoidance under the Debtor Relief Laws or any comparable provisions of any applicable state law.

SECTION 2.03.     No Limitations . (a)  Except for termination of a Guarantor’s obligations hereunder as expressly provided in Section 7.13 , the obligations of each Guarantor hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense or set-off, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality or unenforceability of the Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each Guarantor hereunder shall not be discharged or impaired or otherwise affected by (i) the failure of the Administrative Agent or any other Guaranteed Party to assert any claim or demand or to enforce any right or remedy under the provisions of any Loan Document or otherwise; (ii) any rescission, waiver, amendment or modification of, or any release from any of the terms or provisions of, any Loan Document or any other agreement, including with respect to any other Guarantor under this Agreement; (iii) the release of any security held by the Administrative Agent or any other Guaranteed Party for the Obligations or any of them; (iv) any default, failure or delay, willful or otherwise, in the performance of the Obligations; (v) any Lien granted to, or in favor of, the Administrative Agent or any Guaranteed Party as security for any of the Obligations shall fail to attach or be perfected; (vi) any of the Obligations shall be determined to be void or voidable (including, without limitation, for the benefit of any creditor of any Guarantor) or shall be subordinated to the claims of any Person (including, without limitation, any creditor of any Guarantor); or (vii) any other act or omission that may or might in any manner or to any extent vary the risk of any Guarantor or otherwise operate as a discharge of any Guarantor as a matter of law or equity (other than the indefeasible payment in full in cash of all the Obligations).

(b)            To the fullest extent permitted by applicable law, each Guarantor waives any defense based on or arising out of any defense of the Borrowers or any other Loan Party or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrowers or any other Loan Party, other than the indefeasible payment in full (other than contingent indemnification obligations that survive the termination of the Loan Documents) in cash of all the Obligations, irrespective of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, it being the intent of this Section 2.03 that the obligations of the Guarantors hereunder shall be absolute and unconditional under any and all circumstances. The Administrative Agent and the other Guaranteed Parties may, at their election, compromise or adjust any part of the Obligations, make any other accommodation with the Borrowers or any other Loan Party or exercise any other right or remedy available to them against the Borrowers or any other Loan Party, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Obligations have been fully and indefeasibly paid in full in cash. To the fullest extent permitted by applicable law, each Guarantor waives any defense arising out of any such election even though such election operates, pursuant to applicable law, to impair or to extinguish any right of reimbursement or subrogation or other right or remedy of such Guarantor against the Borrowers or any other Loan Party, as the case may be, or any security.

SECTION 2.04.     Reinstatement . Each of the Guarantors agrees that its guarantee hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or

3

any part thereof, of any Obligation is rescinded or must otherwise be restored by the Administrative Agent or any other Guaranteed Party upon the bankruptcy or reorganization of the Borrowers, any other Loan Party or otherwise. The obligations of the Guarantors under this Article II shall be automatically reinstated if and to the extent that for any reason any payment by or on behalf of any Person in respect of the Obligations is rescinded or must be otherwise restored by any holder of any of the Obligations, whether as a result of any proceedings pursuant to any Debtor Relief Law or otherwise, and each Guarantor agrees that it will indemnify the Administrative Agent and each Guaranteed Party on demand for all reasonable costs and expenses (including all reasonable fees, expenses and disbursements of one outside law firm and reasonably necessary special and local counsel) incurred by the Administrative Agent or such Guaranteed Party in connection with such rescission or restoration, including any such costs and expenses incurred in defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under any Debtor Relief Law.

SECTION 2.05.     Agreement To Pay; Subrogation . In furtherance of the foregoing and not in limitation of any other right that the Administrative Agent or any other Guaranteed Party has at law or in
