Explanation of Responses:
( 1)  Dr. Duyk is a partner of TPG Growth, LLC, which is an affiliate of TPG Biotechnology Partners II, L.P. ("Partners II"), which, as of the date hereof, directly holds the 2,299,907 shares of Series A Preferred Stock, 401,929 shares of Series B Preferred Stock and 419,687 shares of Series C Preferred Stock (collectively, the "TPG Preferred Stock") of the Issuer. The Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock have no expiration date. (Continued footnote 2).
( 2)  The Issuer expects to complete an initial public offering of common stock on or about [September 30], 2010 (the "IPO"). Upon the closing of the IPO, each outstanding share of Series A Preferred Stock and Series C Preferred Stock will be automatically converted into one share of common stock of the Issuer, par value $0.0001 (the "Common Stock"), and each outstanding share of Series B Preferred Stock will be automatically converted into 1.118 shares of Common Stock (the Common Stock converted from the TPG Preferred Stock, the "TPG Common Stock").
( 3)  As part of the IPO, the Common Stock of the Issuer is expected to be listed on The Nasdaq Global Market under the symbol "AMRS".
( 4)  Dr. Duyk disclaims beneficial ownership of the shares of TPG Preferred Stock and TPG Common Stock that are or may be beneficially owned by Partners II or any of its affiliates. 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 Dr. Duyk is, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owner of any equity securities of the Issuer directly held by the Partners II or any of its affiliates.
