1. Amendments. The Credit Agreement is hereby amended as follows:

(a) Section 7.01(b) of the Credit Agreement is hereby amended to read as follows:

(a) upon the earlier of the date that is sixty (60) days after the end of each of the first three (3) fiscal quarters of each fiscal year of Holdings or the date such information is filed with the SEC, a consolidated and consolidating balance sheet of Holdings and its Subsidiaries as at the end of such fiscal quarter, and the related consolidated and consolidating statements of income or operations and consolidated cash flows for such fiscal quarter and for the portion of Holdings’ fiscal year then ended, setting forth in each case in comparative form the figures for the corresponding fiscal quarter of the previous fiscal year and the corresponding portion of the previous fiscal year, all in reasonable detail and certified by a Responsible Officer of Holdings as fairly presenting in all material respects the financial condition, results of operations, shareholders’ equity and cash flows of Holdings and its Subsidiaries in accordance with GAAP, subject only to normal year-end audit adjustments and the absence of footnotes.

(b) A new clause (e) is hereby added at the end of Section 8.06 of the Credit Agreement to read as follows:

(e) the Borrower may make distributions to Holdings so long as Holdings shall in turn contribute such distributions to a newly formed direct Subsidiary permitted to be formed pursuant to Section 8.17, in an amount not to exceed the amount necessary for such newly formed direct Subsidiary of Holdings to consummate a Permitted Acquisition; provided, that, (i) both before and upon giving effect to the payment of such Restricted Payment, on a Pro Forma Basis (x) no Default or Event of Default exists or would result therefrom, and (y) the Loan Parties are in compliance with the financial covenants set forth in Section 8.11 as of the most recent fiscal quarter for which the Borrower was required to deliver financial statements pursuant to Section 7.01(a) or (b) and (ii) any such newly formed direct Subsidiary of Holdings shall become a Guarantor and pledge its assets in accordance with the terms of Sections 7.12 and 7.14.
