GUARANTY PROVISIONS

SECTION 2.1. Company Guaranty. The Guarantor hereby absolutely, unconditionally and irrevocably:

(a) guarantees the full and punctual payment when due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise, of all Obligations of each Designated Borrower (collectively, the “Guaranteed Obligations”) now or hereafter existing, whether for principal, interest (including interest accruing at the then Applicable Rate provided in the Credit Agreement after the occurrence of any Default set forth in Section 8.01(f) or (g) of the Credit Agreement, whether or not a claim for post-filing or post-petition interest is allowed under applicable Law following the institution of a proceeding under bankruptcy, insolvency or similar Laws), fees, reimbursement obligations with respect to the Letters of Credit or otherwise, expenses or otherwise (including all such amounts which would become due but for the operation of the automatic stay under Section 362(a) of the United States Bankruptcy Code, 11 U.S.C. §362(a), and the operation of Sections 502(b) and 506(b) of the United States Bankruptcy Code, 11 U.S.C. §502(b) and §506(b)); and

(b) indemnifies and holds harmless each Lender Party for any and all costs and expenses (including reasonable attorney’s fees and expenses) incurred by such Lender Party in enforcing any rights under this Company Guaranty;

provided that the Guarantor shall only be liable under this Company Guaranty for the maximum amount of such liability that can be hereby incurred without rendering this Company Guaranty, as it relates to the Guarantor, voidable under applicable Law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount. This Company Guaranty constitutes a guaranty of payment when due and not of collection, and the Guarantor specifically agrees that it shall not be necessary or required that any Lender Party exercise any right, assert any claim or demand or enforce any remedy whatsoever against any Loan Party or any other Person before or as a condition to the obligations of the Guarantor hereunder.

SECTION 2.2. Payments Set Aside. To the extent that any payment by or on behalf of the Guarantor is made to any Lender Party, or any Lender Party exercises its right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by such Lender Party in its discretion) to be repaid to a trustee, receiver or any other party, in connection with any proceeding under any Debtor Relief Law or otherwise,

2

then to the extent of such recovery, the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred.

SECTION 2.3. Guaranty Absolute, etc. This Company Guaranty shall in all respects be a continuing, absolute, unconditional and irrevocable guaranty of payment, and shall remain in full force and effect until the Termination Date has occurred. The Guarantor guarantees that the Guaranteed Obligations will be paid strictly in accordance with the terms of each Loan Document under which they arise, regardless of any Law, regulation or order now or hereafter in effect in any jurisdiction affecting any of such terms or the rights of any Lender Party with respect thereto. The liability of the Guarantor under this Company Guaranty shall be absolute, unconditional and irrevocable irrespective of:

(a) any lack of validity, legality or enforceability of any Loan Document;

(b) the failure of any Lender Party:

(i) to assert any claim or demand or to enforce any right or remedy against any Loan Party or any other Person (including any other guarantor) under the provisions of any Loan Document or otherwise, or

(ii) to exercise any right or remedy against any other guarantor (including any Borrower or any other Guarantor) of, or collateral (if any) securing, any Guaranteed Obligation;

(c) any change in the time, manner or place of payment of, or in any other term of, all or any part of the Guaranteed Obligations, or any other extension, compromise or renewal of any Guaranteed Obligation;

(d) any reduction, limitation, impairment or termination of any Guaranteed Obligation for any reason, including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to (and the Guarantor hereby waives any right to or claim of) any defense or setoff, counterclaim, recoupment or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Guaranteed Obligation or otherwise;

(e) any amendment to, rescission, waiver, or other modification of, or any consent to or departure from, any of the terms of any Loan Document;

(f) any addition, exchange or release of any collateral (if any) or of any Person that is (or will become) a guarantor of the Guaranteed Obligations, or any surrender or non perfection of any collateral, or any amendment to or waiver or release or addition to, or consent to or departure from, any other guaranty held by any Lender Party securing any of the Guaranteed Obligations; or

3

(g) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, any Loan Party, any surety or any guarantor.

SECTION 2.4. Setoff. If an Event of Default shall have occurred and be continuing, each Lender, the L/C Issuer and each of their respective Affiliates is hereby authorized at any time and from time to time, after obtaining the prior written consent of the Administrative Agent, to the fullest extent permitted by applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other obligations (in whatever currency) at any time owing by such Lender, the L/C Issuer or any such Affiliate to or for the credit or the account of the Guarantor against any and all of the obligations of the Guarantor now or hereafter existing under this Company Guaranty or any other Loan Document to such Lender or the L/C Issuer, irrespective of whether or not such Lender or the L/C Issuer shall have made any demand under this Company Guaranty or any other Loan Document and although such obligations of the Guarantor may be contingent or unmatured or are owed to a branch or office of such Lender or the L/C Issuer different from the branch or office holding such deposit or obligated on such indebtedness. The rights of each Lender, the L/C Issuer and their respective Affiliates under this Section 2.4 are in addition to other rights and remedies (including other rights of setoff) that such Lender, the L/C Issuer or their respective Affiliates may have. Each Lender and the L/C Issuer agrees to notify the Company and the Administrative Agent promptly after any such setoff and application; provided that the failure to give such notice shall not affect the validity of such setoff and application.

SECTION 2.5. Waiver, etc. The Guarantor hereby waives promptness, diligence, notice of acceptance and any other notice with respect to any of the Guaranteed Obligations and this Company Guaranty and any requirement that any Lender Party protect, secure, perfect or insure any Lien, or any property subject thereto, or exhaust any right or take any action against any Loan Party or any other Person (including any other guarantor) or entity or any collateral securing the Guaranteed Obligations, as the case may be.

SECTION 2.6. Postponement of Subrogation, etc. The Guarantor agrees that it will not exercise any rights which it may acquire by way of rights of subrogation under any Loan Document to which it is a party, nor shall the Guarantor seek or be entitled to seek any contribution or reimbursement from any Loan Party, in respect of any payment made under any Loan Document or otherwise, until following the Termination Date. Any amount paid to the Guarantor on account of any such subrogation rights prior to the Termination Date shall be held in trust for the benefit of the Lender Parties and shall immediately be paid and turned over to the Administrative Agent for the benefit of the Lender Parties in the exact form received by the Guarantor (duly endorsed in favor of the Administrative Agent, if required), to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with Section 2.7; provided that if the Guarantor has made payment to any Lender Party of all or any part of the Guaranteed Obligations and the Termination Date has occurred, then at the Guarantor’s request, the Administrative Agent (on behalf of the Lender Parties) will, at the expense of the Guarantor, execute and deliver to the Guarantor appropriate documents (without recourse and without representation or warranty) necessary to evidence the transfer by subrogation to the Guarantor of an interest in the Guaranteed Obligations resulting from such payment. In furtherance of the foregoing, at all times prior to the Termination Date, the

4

Guarantor shall refrain from taking any action or commencing any proceeding against any Loan Party (or its successors or assigns, whether in connection with a bankruptcy proceeding or otherwise) to recover any amounts in respect of payments made under this Company Guaranty to any of the Lender Parties.

SECTION 2.7. Payments; Application. The Guarantor hereby agrees with each Lender Party as follows:

(a) All payments made by the Guarantor hereunder will be made in Dollars or other applicable Alternative Currency to the Administrative Agent, without setoff, counterclaim or other defense and in accordance with Sections 3.01 and 8.03 of the Credit Agreement, free and clear of and without deduction for any Taxes, the Guarantor hereby agreeing to comply with and be bound by the provisions of Sections 3.01 and 8.03 of the Credit Agreement in respect of all payments made by it hereunder and the provisions of which Sections are hereby incorporated into and made a part of this Company Guaranty by this reference as if set forth herein; provided that references to the “Borrower” in such Sections shall be deemed to be references to the Guarantor, and references to “this Agreement” in such Sections shall be deemed to be references to this Company Guaranty.

(b) All payments made hereunder shall be applied upon receipt as set forth in Section 8.03 of the Credit Agreement.

nor to advise the Guarantor of any fact respecting, or any change in, the financial condition or affairs of any other Loan Party that might become known to any Lender Party at any time, whether or not such Lender Party knows or believes or has reason to know or believe that any such fact or change is unknown to the Guarantor, or might (or does) materially increase the risk of the Guarantor as guarantor, or might (or would) affect the willingness of the Guarantor to continue as a guarantor of the Guaranteed Obligations.

SECTION 3.3. Best Interests.
