On and as of the Amendment No. 4 Effective Date, after giving effect to this Amendment, the Loan Parties hereby represent and warrant to the Administrative Agent and each Lender as follows:

3.1    this Amendment has been duly authorized, executed and delivered by each Loan Party and, assuming the due execution and delivery of this Amendment by each of the other parties hereto, constitutes the legal, valid and binding obligation of such Loan Party enforceable against such Loan Party in accordance with its terms, except as the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting creditors’ rights generally;

3.2    each of the representations and warranties contained in Article VI of the Credit Agreement and in each other Loan Document is true and correct in all material respects (except that any representation or warranty that is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in all respects) with the same effect as if then made (unless expressly stated to relate to an earlier date, in which case such representations and warranties shall be true and correct in all material respects (except that any representation or warranty that is qualified as to “materiality” or “Material Adverse Effect” shall be true and correct in all respects) as of such earlier date);

3.3    no Default or Event of Default has occurred and is continuing; and

3.4    after giving effect to this Amendment, neither the modification of the Credit Agreement affected pursuant to this Amendment nor the execution, delivery, performance or effectiveness of this Amendment (a) impairs

the validity, effectiveness or priority of the Liens granted pursuant to any Loan Document, and such Liens continue unimpaired with the same priority to secure repayment of all Obligations, whether heretofore or hereafter incurred; or (b) requires that any new filings be made or other action taken to perfect or to maintain the perfection of such Liens.

The Borrower agrees to pay promptly (and in any event on the Amendment No. 4 Effective Date) after presentation of an invoice therefor all reasonable and documented out-of-pocket fees and expenses of the Joint Lead Arrangers (including the reasonable and documented fees and out-of-pocket expenses of Moore & Van Allen, PLLC) in connection with the preparation, negotiation, execution and delivery of this Amendment.

5.1    As of the Amendment No. 4 Effective Date, each reference in the Credit Agreement to “this Agreement,” “hereunder,” “hereof,” “herein,” or words of like import, and each reference in the other Loan Documents to the Credit Agreement (including, without limitation, by means of words like “thereunder”, “thereof’ and words of like import), shall mean and be a reference to the Credit Agreement, as amended hereby, and this Amendment and the Credit Agreement shall be read together and construed as a single instrument. Each of the table of contents and lists of Exhibits and Schedules of the Credit Agreement shall be amended to reflect the changes made in this Amendment as of the Amendment No. 4 Effective Date;

5.3    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 Lenders, the Borrower, Lead Arranger or the Administrative 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; and

5.4    This Amendment is a Loan Document.

This Amendment may be executed by the parties hereto in several counterparts (including by facsimile or other electronic imaging means (e.g., “.pdf” or “.tif”), each of which shall be deemed to be an original and all of which shall constitute together but one and the same agreement.

THIS AMENDMENT and any claims, controversy, dispute or cause of action (whether in contract or tort or otherwise) based upon, arising out of or relating to this AMENDMENT and the transactions contemplated hereby shall be governed by, and construed in accordance with, the law of the State of NEW yORK.

The various headings of this Amendment are inserted for convenience only and shall not affect the meaning or interpretation of this Amendment or any provisions hereof.

All communications and notices hereunder shall be given as provided in the Credit Agreement.
