Upon and after the effectiveness of this Amendment, each reference in the Guarantee and Collateral Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Guarantee and Collateral Agreement, and each reference in the other Loan Documents to “the Guarantee and Collateral Agreement”, “thereunder”, “thereof” or words of like import referring to the Guarantee and Collateral Agreement, shall mean and be a reference to the Guarantee and Collateral Agreement as amended hereby.

(c) The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided herein, operate as a waiver of any right, power or remedy of the Secured Parties under any of the Loan Documents, nor, except as expressly provided herein, constitute a waiver or

4

amendment or other modification of any provision of the Credit Agreement, the Guarantee and Collateral Agreement or any other Loan Document. Nothing herein shall be deemed to entitle the Borrower or any other Person to a consent to, or a waiver, amendment or other modification of, any of the terms contained in any Loan Document in similar or different circumstances.

(d) The parties acknowledge and agree that (i) this Amendment, the Consent and any other document executed and delivered in connection herewith do not constitute a novation or termination of the “Credit Agreement Obligations” (as defined in the Loan Documents) under the Credit Agreement as in effect prior to the First Amendment Effective Date, (ii) such “Credit Agreement Obligations” are in all respects continuing with the terms thereof being modified only to the extent provided hereby and (iii) the Liens and security interests granted under the Loan Documents securing such “Credit Agreement Obligations” are in all such respects continuing in full force and effect and shall continue to secure such “Credit Agreement Obligations.”

SECTION 5. Counterparts. This Amendment may be executed by one or more of the parties to this Amendment on any number of separate counterparts, and all of said counterparts taken together shall be deemed to constitute one and the same instrument.

A set of the copies of this Amendment signed by all the parties shall be lodged with the Borrower and the Administrative Agent.

SECTION 6. Severability. Any provision of this Amendment that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.
