Explanation of Responses:
1. Reflects the continuation of a pro rata distribution of shares of common stock of the issuer by Madison Dearborn Partners III, L.P. ("MDP III"), the record and direct beneficial owner of the shares, to its partners, including Madison Dearborn Partners, LLC ("MDP LLC"), the sole general partner of MDP III, on January 25, 2007. The pro rata distribution was commenced by PCA Holdings LLC ("Holdings") on December 7, 2006, as previously reported by the reporting person.
2. The reporting person expressly disclaims beneficial ownership of 11,773,010 shares reported in Table I as beneficially owned, except to the extent of his pecuniary interest therein, and the inclusion of these shares in this report shall not be deemed an admission of beneficial ownership of these shares for purposes of Section 16 or for any other purpose.
3. Holdings is the record and direct beneficial owner of 11,773,010 shares. The shares held by Holdings may be deemed to be beneficially owned by Madison Dearborn Capital Partners III, L.P. ("MDCP III"), the managing member of Holdings, a fund affiliated with MDCP III, MDP III, the sole general partner of MDCP III and the fund affiliated with MDCP III, and MDP LLC. The reporting person is a limited partner of MDP III and may be deemed to have an indirect pecuniary interest in the shares owned by Holdings to the extent of the reporting person's indirect proportionate interest in Holdings. The reporting person is also a managing director but not a member of MDP LLC and therefore does not have a pecuniary interest in the 10,288 shares beneficially owned by MDP LLC.
4. Consists of shares of common stock of the issuer received by the reporting person as a result of the distribution by MDP III to its partners.
