(1)	As of the date of this filing, the Reporting Person (as defined below) owns 9,600,000 shares of Series C Preferred Stock and 2,705,756 shares of Series D Preferred Stock of the Issuer. Upon the consummation of the Issuer's initial public offering of its securities, its Series C and Series D Preferred Stock will each convert automatically to common stock of the Issuer at a conversion ratio of 0.20391517 common shares per 1 share of each such class of Preferred Stock.
(2)	Tarrant Advisors, Inc., a Delaware corporation (the "Reporting Person"), is the general partner of TPG Ventures Professionals, L.P., which is the managing member of TPG Ventures Holdings, L.L.C., which is the sole member of each of TPG Ventures Advisors, L.L.C. and TPG Biotechnology Advisors, L.L.C. TPG Ventures Advisors, L.L.C. is the general partner of TPG Ventures GenPar, L.P., which is the general partner of TPG Ventures, L.P.

(3)	Because of the Reporting Person's relationship to the TPG Funds (as described above), the Reporting Person may be deemed to beneficially own the securities directly owned by the TPG Funds (an aggregate of 9,600,000 shares of Series C Preferred Stock and 2,705,756 shares of Series D Preferred Stock of the Issuer). The Reporting Person may also be deemed to beneficially own such securities to the extent of the greater of its direct or indirect pecuniary interest in the profits or capital accounts of the TPG Funds. Pursuant to Rule 16a-1(a)(4) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this filing shall not be deemed an admission that the Reporting Person is, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owner of any securities beneficially owned in excess of such amount.
