     NOW, THEREFORE, in consideration of the foregoing and the mutual agreements set forth herein, and other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as follows:

     Section 1. Amendments. Effective as of the date hereof, Section VI of the Agreement is hereby amended and restated in its entirety to read as follows:

     “This Agreement shall become effective on the date hereof and shall continue in effect until the date as of which Carlyle or one or more of its affiliates no longer collectively control, in the aggregate, at least 5% of the outstanding shares of the common stock of the Company, or such earlier date as the Company, Carlyle and Investor (for so long as he shall continue to hold at least 10% of the outstanding shares of the common stock of the Company) may mutually agree. This Agreement shall terminate upon the consummation of a public offering of the common stock of the Company pursuant to a registration statement filed in accordance with the Securities Act of 1933, as amended. The provisions of Sections V, VII and VIII and otherwise as the context so requires shall survive the termination of this Agreement.”
