(c)The execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or remedy of the Lenders, the Borrower or the Agent under any of the Loan Documents, nor constitute a waiver or amendment of any other provision of any of the Loan Documents or for any purpose except as expressly set forth herein.

(d)This Amendment shall constitute a Loan Document under the terms of the Amended Credit Agreement.

(e)The (i) Borrower, by its signature below, hereby affirms and confirms its Guaranty of the Guaranteed Obligations (as defined in the Guarantee Agreement) pursuant to the Guarantee Agreement and acknowledges and agrees that such Guaranty shall continue in full force and effect in respect of, and to secure, such Guaranteed Obligations under the Guarantee Agreement and the other Loan Documents and (ii) Borrower and Holdings, by their respective signatures below, hereby affirm and confirm the pledge of and/or grant of a security interest in their assets which are Collateral to secure the Obligations, all as provided in the Security Documents, and acknowledge and agree that such pledge and/or grant shall continue in full force and effect in respect of, and to secure, such Obligations under the Amended Credit Agreement and the other Loan Documents.
