               Section 1.    Defined Terms.  Unless otherwise specifically defined herein, each term used
herein that is defined in the Credit Agreement has the meaning assigned to such term in the Credit
Agreement.  Each reference to "hereof," "hereunder," "herein" and "hereby" and each other similar reference
and each reference to "this Agreement" and each other similar reference contained in the Credit Agreement
shall, after this Amendment becomes effective, refer to the Credit Agreement as amended hereby.

such party has signed a counterpart hereof.

               Section 4.    Effect of Amendment.  The execution, delivery and effectiveness of this
Amendment shall not, except as expressly provided herein, operate as an amendment or a waiver of any right,
power or remedy of any Lender, the Administrative Agent, the Syndication Agent or the Documentation Agents
under any of the Loan Documents, nor, except as expressly provided herein, constitute an amendment or a
waiver of any other provision of any of the Loan Documents.

               Section 5.    Governing Law.  THIS AMENDMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
HEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW
