guarantor or surety other than the actual payment and performance by Guarantor under this Guaranty.

(c) This is a guaranty of payment and not of collection. Administrative Agent and Lenders may invoke the benefits of this Guaranty before pursuing any remedies against any Obligor or any other Person and before proceeding against any Security now or hereafter existing for the payment or performance of any of the Obligations.

Any transfer by subrogation which is made as contemplated in Section 6 prior to any such payment or payments shall (regardless of the terms of such transfer) be automatically voided upon the making of any such payment or payments, and all rights so transferred shall thereupon revert to and be vested in Administrative Agent and Lenders.

(a) notice of the incurrence of any Obligation by any Restricted Person, and notice of any kind concerning the assets, liabilities, financial condition, creditworthiness, businesses, prospects, or other affairs of any Restricted Person (it being understood and agreed that: (i) Guarantor shall take full responsibility for informing itself of such matters, (ii) neither Administrative Agent nor any other Guaranteed Party shall have any responsibility of any kind to inform Guarantor of such matters, and (iii) Guaranteed Parties are hereby authorized to assume that Guarantor, by virtue of its relationships with Borrower which are independent of this Guaranty, has full and complete knowledge of such matters whenever Guaranteed Parties extend credit to any Restricted Person or take any other action which may change or increase Guarantor’s liabilities or losses hereunder).

(b) notice that Administrative Agent, any Lender, any Obligor, or any other Person has taken or omitted to take any action under any Obligation Document or any other agreement or instrument relating thereto or relating to any Obligation.

(d) notice of intention to accelerate, notice of acceleration, protest, notice of protest, notice of any exercise ofremedies (as described in the following Section 5 or otherwise), and all other notices of any kind whatsoever.

Section 5. Exercise of Remedies.

No failure on the part of Administrative Agent or any Lender to exercise, and no delay in exercising, any right hereunder or under any other Obligation Document shall operate as a waiver thereof; nor shall any single or partial exercise of any right preclude any other or further exercise thereof or the exercise of any other right. The rights, powers and remedies of Administrative Agent and each Lender provided herein and in the other Obligation Documents are cumulative and are in addition to, and not exclusive of, any other rights, powers or remedies provided by law or in equity. The rights of Administrative Agent and each Lender hereunder are not conditional or contingent on any attempt by Administrative Agent or any Lender to exercise any of its rights under any other Obligation Document against any Obligor or any other Person.

Section 6. Limited Subrogation.

(a) Until all of the Obligations have been paid and performed in full Guarantor shall have no right to exercise any right of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter have against or to any Obligor or any Security in connection with this Guaranty, and Guarantor hereby waives any rights to enforce any remedy which Guarantor may have against any Restricted Person and any right to participate in any Security until such time. If any amount shall be paid to Guarantor on account of any such subrogation or other rights, any such other remedy, or any Security at any time when all of the Obligations and all other expenses guaranteed pursuant hereto shall not have been paid in full, such amount shall be held in trust for the benefit of Administrative Agent, shall be segregated from the other funds of Guarantor and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portion of the Obligations, whether matured or unmatured, in such order as Administrative Agent shall elect.

(b) If Guarantor shall make payment to Administrative Agent of all or any portion of the Obligations and if all of the Obligations shall be finally paid in full in cash, Administrative Agent will, at Guarantor’s request and expense, execute and deliver to Guarantor (without recourse, representation or warranty) appropriate documents necessary to evidence the transfer by subrogation to Guarantor of an interest in the Obligations resulting from such payment by Guarantor; provided that such transfer shall be subject to Section 3(d) above and that without the

consent of Administrative Agent (which Administrative Agent may withhold in its discretion) Guarantor shall not have the right to be subrogated to any claim or right against any Obligor which has become owned by Administrative Agent or any Lender, whose ownership has otherwise changed in the course of enforcement of the Obligation Documents.

Section 7. Successors and Assigns. Guarantor’s rights or obligations hereunder may not be assigned or delegated, but this Guaranty and such obligations shall pass to and be fully binding upon the successors of Guarantor, as well as Guarantor. This Guaranty shall apply to and inure to the benefit of Administrative Agent and Lenders and their successors or assigns who acquire their interests in accordance with the assignment provisions of the Credit Agreement. Without limiting the generality of the immediately preceding sentence, Administrative Agent and each Lender may assign, grant a participation in, or otherwise transfer any Obligation held by it or any portion thereof, and Administrative Agent and each Lender may assign or otherwise transfer its rights or any portion thereof under any Obligation Document, to any other Person, and such other Person shall thereupon become entitled to all of the benefits in respect thereof granted to Administrative Agent or such Lender hereunder unless otherwise expressly provided by Administrative Agent or such Lender in connection with such assignment or transfer.

Section 8. Subordination and Set Off. Guarantor hereby subordinates and makes inferior to the Obligations any and all indebtedness now or at any time hereafter owed by Restricted Persons to Guarantor. Guarantor agrees that after the occurrence and during the continuance of any Event of Default (including the commencement and continuation of any proceeding under any Debtor Relief Law relating to any Restricted Person) it will neither permit any Restricted Person to repay such indebtedness or any part thereof nor accept payment from any Restricted Person of such indebtedness or any part thereof without the prior written consent of Administrative Agent. If Guarantor receives any such payment without the prior written consent of Administrative Agent, the amount so paid shall be held in trust for the benefit of Lenders, shall be segregated from the other funds of Guarantor, and shall forthwith be paid over to Administrative Agent to be held by Administrative Agent as collateral for, or then or at any time thereafter applied in whole or in part by Administrative Agent against, all or any portions of the Obligations, whether matured or unmatured, in such order as Administrative Agent shall elect. In any proceeding under any Debtor Relief Law relating to any Restricted Person, the Guaranteed Parties shall be entitled to receive payment in full in cash of all Obligations (including all interest and expenses accruing after the commencement of a proceeding under any Debtor Relief Law, whether or not constituting an allowed claim in such proceeding) before Guarantor receives payment of any Subordinated Obligation.

If an Event of Default shall have occurred and be continuing, each Guaranteed Party is hereby authorized at any time and from time to time after obtaining the prior written consent of 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 Guaranteed Party to or for the credit or the account of Guarantor against any and all of the obligations of Guarantor now or hereafter existing under this Guaranty to such Guaranteed Party. The rights of each Guaranteed Party under this Section are in addition to other rights and remedies (including other rights of set off) that such Guaranteed Party may have.

(h) The direct or indirect value of the consideration received and to be received by Guarantor in connection herewith is reasonably worth at least as much as the liability and obligations of Guarantor hereunder, and the incurrence of such liability and obligations in return for such consideration may reasonably be expected to benefit Guarantor, directly or indirectly.
