Without limiting the generality of the foregoing, or of Paragraph 6 hereof, it is understood that the Administrative Agent, the Issuing Bank and the Lenders, or any of them, may, without exonerating or releasing the Guarantor, give up, or modify or abstain from perfecting or taking advantage of any security for the Guaranteed Obligations and accept or make any compositions or arrangements, and realize upon any security for the Guaranteed Obligations when, and in such manner, and with or without notice, all as the Administrative Agent, the Issuing Bank and the Lenders may deem expedient.

6. Guaranty Unconditional. The Guarantor acknowledges and agrees that no change in the nature or terms of the Guaranteed Obligations or any of the Guaranteed Agreements, or other agreements, instruments or contracts evidencing, related to or attendant with the Guaranteed Obligations (including any novation), shall discharge all or any part of the liabilities and obligations of the Guarantor pursuant to this Parent Guaranty; it being the purpose and intent of the Guarantor, the Administrative Agent, the Issuing Bank and the Lenders that the covenants, agreements and all liabilities and obligations of the Guarantor hereunder are absolute, unconditional and irrevocable under any and all circumstances. Without limiting the generality of the foregoing, the Guarantor agrees that until each and every one of the covenants and agreements of this Parent Guaranty is fully performed, the Guarantor’s undertakings hereunder shall not be released, in whole or in part, by any action or thing which might, but for this paragraph of this Parent Guaranty, be deemed a legal or equitable discharge of a surety or guarantor, or by reason of any waiver, omission of the Administrative Agent, the Issuing Bank and the Lenders, or any of them, or their failure to proceed promptly or otherwise, or by reason of any action taken or omitted by the Administrative Agent, the Issuing Bank and the Lenders, or any of them, whether or not such action or failure to act varies or increases the risk of, or affects the rights or remedies of, the Guarantor or by reason of any further dealings between the Borrower on the one hand and the Administrative Agent, the Issuing Bank and the Lenders, or

3

any of them, on the other hand or any other guarantor or surety, and the Guarantor hereby expressly waives and surrenders any defense to its liability hereunder based upon, and shall be deemed to have consented to, any of the foregoing acts, omissions, things, agreements or waivers.

7. Setoff. The Administrative Agent, the Issuing Bank and the Lenders may, without demand or notice of any kind upon or to the Guarantor, at any time or from time to time when any amount shall be due and payable hereunder by the Guarantor, if the Borrower shall not have timely paid any of the Guaranteed Obligations after the lapse of any applicable cure period, appropriate and apply to any portion of the Guaranteed Obligations hereby guaranteed, and in such order of application as the Administrative Agent, the Issuing Bank and the Lenders may from time to time elect, any property, balances, credit accounts or moneys of the Guarantor in the possession of the Administrative Agent, the Issuing Bank and the Lenders, or any of them, or under any of their control for any purpose.

8. Loans In Excess of Maximum Parent Guaranty Liability. The creation or existence from time to time of Guaranteed Obligations in excess of the amount committed to or outstanding on the date of this Parent Guaranty is hereby authorized, without notice to the Guarantor, and shall in no way impair or affect this Parent Guaranty or the rights of the Administrative Agent, the Issuing Bank and the Lenders herein. The Guarantor agrees that the obligations guaranteed hereunder may at any time and from time to time exceed the Maximum Guaranty Liability of the Guarantor, without impairing its liability under this Parent Guaranty or affecting the rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder. It is the intention of the Guarantor and the Administrative Agent, the Issuing Bank and the Lenders that the Guarantor’s obligations hereunder shall be in, but not in excess of, the maximum amount permitted by applicable Federal or state bankruptcy, insolvency, fraudulent conveyance or transfer, or similar laws (the “Applicable Laws”). To that end, but only to the extent such obligations would otherwise be subject to avoidance under the Applicable Laws if the Guarantor is not deemed to have received valuable consideration, fair value, or reasonably equivalent value for its obligations under this Parent Guaranty, the Guarantor’s obligations under this Parent Guaranty shall be reduced to that amount which, after giving effect hereto, would not render the Guarantor insolvent, or leave the Guarantor with unreasonably small capital to conduct its business or cause the Guarantor to have incurred debts (or intended to have incurred debts) beyond its ability to pay such debts as they mature, at the time such obligations are deemed to have been incurred under the Applicable Laws. As used herein, the terms “insolvent” and “unreasonably small capital” shall likewise be determined in accordance with the Applicable Laws.

9. Bankruptcy of Borrower. Upon the bankruptcy or winding up or other distribution of assets of the Borrower or of any surety or guarantor other than the Guarantor for any Guaranteed Obligations of the Borrower to the Administrative Agent, the Issuing Bank or the Lenders, the Administrative Agent’s, the Issuing Bank’s and the Lenders’ rights against the Guarantor shall not be affected or impaired by the Administrative Agent’s, the Issuing Bank’s or any of the Lenders’ omission to prove its or their claim, as appropriate, or to prove its or their full claim, as appropriate, and the Administrative Agent, the Issuing Bank and the Lenders may prove such claims as they see fit and may refrain from proving any claim and in their respective discretion they may value as they see fit or refrain from valuing any security held by the

4

Administrative Agent, the Issuing Bank and the Lenders, or any of them, without in any way releasing, reducing or otherwise affecting the liability to the Administrative Agent, the Issuing Bank and the Lenders of the Guarantor.

10. Application of Payments. Any amount received by the Administrative Agent, the Issuing Bank or any of the Lenders from whatsoever source and applied toward the payment of the Guaranteed Obligations shall be applied in the order of application set forth in the Facility A Loan Agreement and the Facility B Loan Agreement, as applicable; provided, however, that if any Lender obtains payment from any source on account of the Facility A Loans and Facility B Loans made by it in excess of its ratable share of the Facility A Loans and Facility B Loans, such Lender shall forthwith purchase from the other Lenders such participations in the Facility A Loans and Facility B Loans as provided in the Facility A Loan Agreement and Facility B Loan Agreement, respectively.

11. Waivers of Guarantor. The Guarantor hereby expressly waives: (a) notice of acceptance of this Parent Guaranty, (b) notice of the existence or creation of all or any of the Guaranteed Obligations, (c) presentment, demand, notice of dishonor, protest, and all other notices whatsoever, (d) all diligence in collection or protection of or realization upon the Guaranteed Obligations or any part thereof, any obligation hereunder, or any security for any of the foregoing, and (e) until the Administrative Agent, the Issuing Bank and the Lenders have been indefeasibly paid in full, all rights of subrogation, indemnification, contribution and reimbursement from the Borrower, all rights to enforce any remedy which the Administrative Agent, the Issuing Bank and the Lenders, or any of them, may have against the Borrower and any benefit of, or right to participate in, any collateral or security now or hereinafter held by the Administrative Agent, the Issuing Bank or any of the Lenders in respect of the Guaranteed Obligations, even upon payment in full of the Guaranteed Obligations, except to the extent such waiver would be expressly prohibited by Applicable Law. If a claim is ever made upon the Administrative Agent, the Issuing Bank or any of the Lenders for the repayment or recovery of any amount or amounts received by such Person in payment of any of the Guaranteed Obligations and such Person repays all or part of such amount by reason of (a) any judgment, decree or order of any court or administrative body having jurisdiction over such Person or any of its property, or (b) any settlement or compromise of any such claim effected by such Person with any such claimant, including the Borrower, then in such event the Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon the Guarantor, notwithstanding any revocation hereof or the cancellation of any promissory note or other instrument evidencing any of the Guaranteed Obligations, and the Guarantor shall be and remain obligated to such Person hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by such Person.

12. Assignment of Guaranteed Obligations. The Administrative Agent, the Issuing Bank and the Lenders may each, to the extent permitted under the Facility A Loan Agreement and Facility B Loan Agreement, and without notice of any kind, sell, assign or transfer all or any part of the Guaranteed Obligations, and in such event each and every immediate and successive assignee, transferee, or holder of all or any of the Guaranteed Obligations, shall have the right to enforce this Parent Guaranty, by suit or otherwise, for the benefit of such assignee, transferee or holder as fully as if such assignee, transferee or holder were herein by name specifically given such rights, powers and benefits, but the Administrative Agent, the Issuing Bank and the Lenders

5

shall have an unimpaired right, to enforce this Parent Guaranty for the benefit of the Administrative Agent, the Issuing Bank and the Lenders, as to so much of the Guaranteed Obligations as the Administrative Agent, the Issuing Bank and the Lenders have not sold, assigned or transferred.

13. Remedies Cumulative. No delay by the Lenders, the Issuing Bank and the Administrative Agent, or any of them, in the exercise of any right or remedy shall operate as a waiver thereof, and no single or partial exercise by the Lenders, the Issuing Bank and the Administrative Agent, or any of them, of any right or remedy shall preclude other or further exercise thereof or the exercise of any other right or remedy. No action by the Lenders, the Issuing Bank and the Administrative Agent, or any of them, permitted hereunder shall in any way impair or affect this Parent Guaranty. For the purpose of this Parent Guaranty, the Guaranteed Obligations shall include, without limitation, all Guaranteed Obligations of the Borrower, to the Administrative Agent, the Issuing Bank and the Lenders, notwithstanding any right or power of any third party, individually or in the name of the Borrower, the Administrative Agent, the Issuing Bank or the Lenders, or any of them, to assert any claim or defense as to the invalidity or unenforceability of any such Guaranteed Obligation, and no such claim or defense shall impair or affect the obligations of the Guarantor hereunder.

14. Successors and Assigns. This Parent Guaranty shall be binding upon the Guarantor, its successors and assigns and inure to the benefit of the successors and assigns of the Administrative Agent, the Issuing Bank and the Lenders.

All costs and expenses, including reasonable attorneys’ fees and expenses, incurred by the Administrative Agent, the Issuing Bank and the Lenders, or any of them, in obtaining performance of or collecting payments due under this Parent Guaranty to the extent permitted by the Facility A Loan Agreement and Facility B Loan Agreement, as applicable, shall be deemed part of the Guaranteed Obligations guaranteed hereby.
