6.2Reaffirmation of Loan Documents and Liens.  Any and all of the terms and provisions of the Agreement and the Loan Documents shall, except as amended and modified hereby, remain in full force and effect.  Each Borrower hereby agrees that the amendments and modifications herein contained shall in no manner affect or impair the liabilities, duties and obligations of such Borrower or any Guarantor under the Agreement and the other Loan Documents or the Liens securing the payment and performance thereof.

6.3Parties in Interest.  All of the terms and provisions of this Amendment shall bind and inure to the benefit of the parties hereto and their respective successors and assigns.

Fifth Amendment to Amended and Restated Credit Agreement – Page 5

65179745.4

 delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument; signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document.  However, this Amendment shall bind no party until the Borrowers, the Guarantors, the Lenders (or at least the requisite percentage thereof), and the Administrative Agent have executed a counterpart.  Delivery of photocopies of the signature pages to this Amendment by facsimile or electronic mail shall be effective as delivery of manually executed counterparts of this Amendment.

6.6Complete Agreement.  THIS AMENDMENT, THE AGREEMENT, AND THE OTHER LOAN DOCUMENTS REPRESENT THE FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR, CONTEMPORANEOUS OR ORAL AGREEMENTS OF THE PARTIES.  THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
