** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) The 6,923,078 shares of Series F Convertible Preferred stock of Ceres, Inc., a Delaware corporation (the "Issuer"), were held by Warburg Pincus Private Equity IX, L.P., a Delaware limited partnership ("WP IX"), and automatically converted upon the closing of the Issuer's initial public offering on a one-for-one-third basis into 2,307,692 shares of common stock, par value $0.01 (the "Common Stock"), of the Issuer.
(2) Warburg Pincus IX LLC, a New York limited liability company ("WP IX GP"), is the general partner of WP IX. Warburg Pincus Partners LLC, a New York limited liability company ("WP Partners"), is the sole member of WP IX GP. Warburg Pincus & Co., a New York general partnership ("WP"), is the managing member of WP Partners. Warburg Pincus LLC, a New York limited liability company ("WP LLC"), manages WP IX. Charles R. Kaye and Joseph P. Landy are the Managing General Partners of WP and the Co-Presidents and Managing Members of WP LLC and may be deemed to control WP IX, WP IX GP, WP Partners, WP and WP LLC (together with Messrs. Kaye and Landy, the "Warburg Pincus Reporting Persons").
(3) By reason of the provisions of Rule 16a-1 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), WP IX GP, WP Partners, WP, WP LLC and Messrs. Kaye and Landy may be deemed to be beneficial owners of the Common Stock of the Issuer held by WP IX. Pursuant to Rule 16a-1(a)(4) of the Exchange Act, each of the Warburg Pincus Reporting Persons, other than WP IX, herein states that this Form 4 shall not be deemed an admission that it or he is the beneficial owner of any of the Common Stock or any other securities of the Issuer reported in this Form 4. Each of the Warburg Pincus Reporting Persons disclaims beneficial ownership of such securities, except to the extent it or he has a pecuniary interest in such securities.
(4) The Convertible Subordinated Promissory Note (the "Convertible Note") was purchased by WP IX in connection with an August 2011 financing. The Convertible Note automatically converted into 153,115 shares of Common Stock upon the closing of the Issuer's initial public offering ("IPO") at a price per share equal to the public offering price with a 20% discount. Since the public offering price was $13.00, the price per share was $10.40.
