Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) See Exhibit 99.
(2) Under the terms of the contractual arrangements among the CCMP Capital Funds, CCMP Capital Associates and CCMP Capital (collectively, the "CCMP Fund Entities"), Mr. Walsh is deemed to hold these shares for the benefit of the CCMP Fund Entities and must vote or dispose of such shares upon the direction of CCMP Capital. CCMP Capital is, therefore, deemed to indirectly beneficially own such shares. Mr. Walsh disclaims beneficial ownership of the securities to the extent if exceeds his pecuniary interest therein and the inclusion of the shares in this report shall not be deemed to be an admission of beneficial ownership of the reported shares for the purposes of Section 16 or otherwise.
