5. Amendment to Section 1.01 of the Credit Agreement. During the Forbearance Period, Section 1.01 of the Credit Agreement is hereby amended, effective as of July 18, 2008, by deleting the defined term “Applicable Rate” in its entirety and replacing it with the following:

“Applicable Rate” means, from time to time, the following percentages per annum, based upon, as of any date of determination, the Consolidated Leverage Ratio as set forth in the most recent Compliance Certificate received by Administrative Agent pursuant to Section 6.02(a):

Level	Consolidated Leverage Ratio	LIBOR Interest Margin	Base Rate Interest Margin	Commitment Fee
I	Less than or equal to 3.00 to 1.00	4.25%	2.75%	.75%
II	Greater than 3.00 to 1.00 but less than or equal to 4.00 to 1.00	4.50%	3.00%	.75%

The Compliance Certificate shall state that the Consolidated Leverage Ratio has been calculated in good faith and in accordance with GAAP, provided that if changes in such Consolidated Leverage Ratio are required as a result of the Borrower’s outside auditor having modified the numbers from which the Consolidated Leverage Ratio is derived, the Interest Margin and Commitment Fee shall be retroactively recalculated.
