Explanation of Responses:

1. Pursuant to the net exercise provisions of the Warrants, rather than paying cash for the exercise price of the Warrants, the shareholder used shares of Common Stock that would have otherwise been issuable under the Warrants as payment for the exercise price. Therefore, the price paid for the shares actually acquired by the shareholder also includes the exercise price paid for the shares retained by the issuer as payment for the exercise price. The value of the shares of Common Stock used in accordance with the net exercise provision of the Warrants was $19.19 per share.

2. The Reporting Person is one of several managing members of the sole general partner of Welsh, Carson, Anderson & Stowe IX, L.P. Pursuant to Instruction (4)(b)(iv) of Form 4, the Reporting Person has elected to report as indirectly beneficially owned the entire number of securities beneficially owned by such limited partnership. The Reporting Person disclaims beneficial ownership of any securities, and any proceeds thereof, that exceed his or her pecuniary interest therein, and/or that are not actually distributed to him or her.

3. The Reporting Person is one of several controlling stockholders of WCAS Management Corporation. Pursuant to Instruction (4)(b)(iv) of Form 4, the Reporting Person has elected to report as indirectly beneficially owned the entire number of securities beneficially owned by such corporation.
