Explanation of Responses:

1. Each share of our Series F Preferred Stock and Series E-2 Preferred Stock will convert into Common Stock immediately prior to the completion of the Issuer's initial public offering pursuant to its terms.

2. Consists of (i) 1,309,155 shares of Common Stock underlying Series F Preferred Stock held by U.S. Venture Partners Select Fund I, L.P. ("USVP SFI") on its own behalf and as a nominee for U.S. Venture Partners Select Fund I-A, L.P. ("USVP SFI-A" and, together with USVP SFI, the "USVP Select Funds"), (ii) 1,610,903 shares of Common Stock underlying Series E-2 Preferred Stock and 295,906 shares of Common Stock underlying Series F Preferred Stock held by U.S. Venture Partners XII, L.P. ("USVP XII"), and (iii) 81,755 shares of Common Stock underlying Series E-2 Preferred Stock and 15,017 shares of Common Stock underlying Series F Preferred Stock held by U.S. Venture Partners XII-A, L.P. ("USVP XII-A" and, together with USVP XII, the "USVP XII Funds").

3. Presidio Management Group XII, L.L.C. ("PMG XII") is the general partner of USVP XII and USVP XII-A and may be deemed to have sole voting and dispositive power with respect to the shares held by USVP XII and USVP XII-A. Presidio Management Group Select Fund I, L.L.C. ("PMG Select") is the general partner of USVP SFI and USVP SFI-A and may be deemed to have sole voting and dispositive power with respect to the securites held by USVP SFI and USVP SFI-A.

4. The Reporting Person is the managing partner and a managing member of each of PMG XII and PMG Select, and may be deemed to share voting and dispositive power with respect to the securites described herein. The Reporting Person disclaims beneficial ownership of such holdings, except to the extent of his pecuniary interest in the shares.
