2.    The definition of “Change of Control “ set forth in Section 1.1 [Definitions] of the Credit Agreement is hereby amended and restated in its entirety as follows:

Change of Control shall mean any “person” or “group” (as such terms are used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), shall become the “beneficial owner” (as defined in Rules 13(d)-3 and 13(d)-5 under the Exchange Act), directly or indirectly, of more than 50% of the Equity Interests of the Parent.

3.    The amendment set forth in Section 2 of this Amendment shall not become effective until the Administrative Agent has received the following, each in form and substance acceptable to the Administrative Agent:

4.    The Loan Parties hereby reconfirm and reaffirm that all representations and warranties, agreements and covenants made by and pursuant to the terms and conditions of the Credit Agreement and in each other Loan Document are true and correct in all material respects (without duplication of any materiality qualifier contained therein), before and after giving effect to this Amendment, as though made on and as of the date hereof, except for those made specifically as of another date, in which case such representations and warranties shall be true and correct in all material respects as of such date or time.
