Explanation of Responses:

1. The amounts shown represent the beneficial ownership of the Issuer's securities by J.P. Morgan Partners (23A SBIC), L.P. ("JPM 23A SBIC"), a portion of which may be deemed attributable to the reporting person because the reporting person is a managing director of J.P. Morgan Partners (23A SBIC Manager), Inc., the general partner of JPM 23A SBIC, a partner of J.P. Morgan Partners, LLC, the investment advisor to JPM 23A SBIC and a limited partner of JPMP Master Fund Manager, L.P. ("MF Manager") the limited partner of JPM 23A SBIC. The actual pro rata portion of such beneficial ownership that may be deemed attributable to the reporting person is not readily determinable because it is subject to several variables, including the internal rate of return and vesting within JPM 23A SBIC and within MF Manager. The Reporting Person disclaims beneficial ownership in the securities to the extent it exceeds his pecuniary interest therein. *(continued under remarks)
