9

Except as expressly modified hereby, all terms and provisions of the Credit Agreement and all other Loan Documents remain in full force and effect and nothing contained in this Amendment shall in any way impair the validity or enforceability of the Credit Agreement or the Loan Documents, or alter, waive, annul, vary, affect, or impair any provisions, conditions, or covenants contained therein or any rights, powers, or remedies granted therein. This Amendment shall not constitute a modification of the Credit Agreement or any of the other Loan Documents or a course of dealing with Administrative Agent or the Lenders at variance with the Credit Agreement or the other Loan Documents such as to require further notice by Administrative Agent or any Lender to require strict compliance with the terms of the Credit Agreement and the other Loan Documents in the future, except in each case as expressly set forth herein.

10. Governing Law; Jurisdiction; Waiver of Jury Trial.

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. Sections 10.04, 10.14 and 10.15 of the Credit Agreement are hereby incorporated herein by this reference.

10

11. Severability.

If any provision of this Amendment is held to be illegal, invalid or unenforceable, (a) the legality, validity and enforceability of the remaining provisions of this Amendment shall not be affected or impaired thereby and (b) the parties shall endeavour in good faith negotiations to replace the illegal, invalid or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the illegal, invalid or unenforceable provisions. The invalidity of a provision in a particular jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

12. References.

All references in the Credit Agreement to “this Agreement”, “hereunder”, “hereof” or words of like import referring to the Credit Agreement and each reference to the “Credit Agreement”, (or the defined term “Agreement”, “thereunder”, “thereof” of words of like import referring to the Credit Agreement) in the other Loan Documents shall mean and be a reference to the Credit Agreement as amended hereby and giving effect to the amendments contained in this Amendment.
