Explanation of Responses:
1. Represents a transfer of direct ownership to certain limited partners of SCF-VI, L.P. (SCF-VI). Pursuant to the terms of its limited partnership agreement, dated July 15, 2005, SCF-VI was scheduled to expire. In connection therewith, certain of SCF-VI's limited partners elected to receive a pro rata distribution of SCF-VI's shares of the registrant's common stock. The remaining shares held by SCF-VI are held for the benefit of its limited partners who chose to extend the partnership life and leave their shares invested with SCF-VI. Following the distribution reported in this Form 4, SCF-VI, SCF-VII, L.P., a Delaware limited partnership (SCF-VII), and SCF-VII(A), L.P., a Delaware limited partnership (SCF-VIIA), in the aggregate own 13,809,154 shares of common stock.
2. SCF Partners, Inc. (formerly named LE Simmons & Associates Inc), a Delaware corporation (SCFP), manages each of SCFVI, GP, Limited Partnership (SCFVIGP), SCFVII, GP Limited Partnership (SCFVIIGP) and SCF-VII(A), GP Limited Partnership (SCFVIIAGP), each of which are Delaware limited partnerships. Additionally, SCFVIGP is the sole general partner of SCF-VI, SCFVIIGP is the sole general partner of SCF-VII, and SCF-VIIAGP is the sole general partner of SCF-VIIA. Collectively, SCFP, SCFVIGP, SCFVIIGP, SCFVIIAGP, SCF-VI, SCF-VII and SCF-VIIA are the reporting entities. Based on the reporting person's affiliation with the reporting entities, SCFP may be deemed to beneficially own all of the shares of common stock of the registrant beneficially owned or deemed to be beneficially owned by the reporting entities.
