The Guarantor hereby subordinates, and shall cause each of its Subsidiaries to subordinate, any and all debts, liabilities and other obligation (including, without limitation, all payment obligations) owed to the Guarantor or any such Subsidiary, as the case may be, by the Borrower (the “Subordinated Obligations”) to the Guaranteed Obligations to the extent and in the manner hereinafter set forth in this Section 6.1:

(a) Prohibited Payments, Etc. Except during the occurrence and continuance of an Event of Default as defined in the Credit Agreement (including, without limitation, the commencement and continuation of any proceeding under any Bankruptcy Law), the Guarantor and its Subsidiaries may receive payments from the Borrower on account of the Subordinated Obligations. After the occurrence, and during the continuance, of an Event of Default (including, without limitation, the commencement and continuation of any proceeding under any Bankruptcy Law), unless the Lender otherwise agrees, the

15

Guarantor and its Subsidiaries shall not demand, accept or take any action to collect any payment on account of the Subordinated Obligations.

(b) Prior Payment of Guaranteed Obligations. In any proceeding under any Bankruptcy Law relating to the Borrower, the Guarantor agrees that the Lender and the Lenders shall be entitled to receive payment in full in cash of all Guaranteed Obligations (including, without limitation, all interest and expenses accruing after the commencement of a proceeding under any Bankruptcy Law, whether or not constituting an allowed claim in such proceeding (“Post Petition Interest”)) before the Guarantor or any of its Subsidiaries receive payment of any Subordinated Obligations.

(c)  Turn-Over. After the occurrence and during the continuance of an Event of Default (including the commencement and continuation of any proceeding under any bankruptcy law relating to the Borrower), the Guarantor and its Subsidiaries shall, if the Lender so requests, collect, enforce and receive payments on account of the Subordinated Obligations as trustee for the Lender and deliver such payments to the Lender on account of the Guaranteed Obligations (including all Post Petition Interest), together with any necessary endorsements or other instruments of transfer, but without reducing or affecting in any manner the liability of the Guarantor under the other provisions of this Guarantee.

(d) Lender Authorization. After the occurrence and during the continuance of an Event of Default (including the commencement and continuation of any proceeding under any bankruptcy law relating to the Borrower), the Lender is authorized and empowered (but without any obligation to so do), in its discretion, (i) in the name of the Guarantor and its Subsidiaries, to collect and enforce, and to submit claims in respect of, Subordinated Obligations and to apply any amounts received thereon to the Guaranteed Obligations (including any and all Post Petition Interest), and (ii) to require the Guarantor and its Subsidiaries (A) to collect and enforce, and to submit claims in respect of,

16

Subordinated Obligations and (B) to pay any amounts received on such obligations to the Lender for application to the Guaranteed Obligations (including any and all Post Petition Interest).

(e) Liens. The Guarantor hereby subordinates, and shall cause each of its Subsidiaries to subordinate, any and all present and future Liens of the Guarantor or any such Subsidiary, as the case may be, on any property or assets of the Borrower, to any and all present and future Liens of the Lender, or any security trustee acting on their behalf granted to secure the Obligations of the Borrower under the Loan Documents (the “Senior Indebtedness”), notwithstanding the respective times of attachment of the interests of the Lender, the Guarantor or its Subsidiaries, or the respective times that the Subordinated Obligations or the Senior Indebtedness arise or are incurred.

Without limiting the generality of clause (c) of the immediately preceding sentence, the Lender may assign or otherwise transfer all or any portion of its rights and obligations under this Agreement (including, without limitation, the Promissory Note held by it) to any other Person with the prior written consent of the Guarantor (such consent not to be unreasonably withheld or delayed, and such consent not to be required after the occurrence and during the continuance of an Event of Default), and such other Person shall thereupon become vested with all the benefits in respect thereof granted to such assignor herein. The Guarantor shall not have the right to assign its rights hereunder or any interest herein without the prior written consent of the Lender.

17
