(c) All representations and warranties of the Borrower contained in Article V of the Credit Agreement are true and correct on and as of the Amendment Effective Date after giving effect to this Amendment, except to the extent that any such representation and warranty specifically relates to an earlier date, in which case they shall be true and correct as of such earlier date after giving effect to this Amendment.

6. Miscellaneous.

(a) Except as expressly amended or modified hereby or by the other Amendment Documents, all terms, covenants and provisions of the Credit Agreement and the other Loan Documents are and shall remain in full force and effect and all references therein to such Credit Agreement shall henceforth refer to the Credit Agreement as modified by this Amendment. The Borrower hereby fully ratifies and affirms each Loan Document to which it is a party. This Amendment shall be deemed incorporated into, and a part of, the Credit Agreement.

4

other parties hereto, as applicable, shall bind the Borrower or such other party, respectively, with the same force and effect as the delivery of a hard copy original. Any failure by the Lender to receive the hard copy executed original of such document shall not diminish the binding effect of receipt of the facsimile transmitted executed original of such document of the party whose hard copy page was not received by the Lender.

(e) This Amendment contains the entire and exclusive agreement of the parties hereto with reference to the matters discussed herein. This Amendment supersedes all prior drafts and communications with respect thereto. This Amendment may not be amended except by a written agreement executed by the Borrower and the Lender.

(f) If any term or provision of this Amendment shall be deemed prohibited by or invalid under any applicable law, such provision shall be invalidated without affecting the remaining provisions of this Amendment or the Credit Agreement, respectively.

(g) The Borrower covenants to pay to or reimburse the Lender, upon demand, for all reasonable and documented costs and expenses (including allocated costs of in-house counsel) incurred in connection with the development, preparation, negotiation, execution and delivery, and enforcement of this Amendment.
