Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	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 Convertible Subordinated Promissory Note (the "Convertible Note") of Ceres, Inc., a Delaware corporation (the "Issuer"), is held by Warburg Pincus Private Equity IX, L.P., a Delaware limited partnership ("WP IX"), and is automatically convertible, subject to the terms and conditions set forth therein, into the Issuer's common stock, par value $0.01 (the "Common Stock"), upon the consummation of a qualified initial public offering ("IPO") of the Common Stock at a price per share equal to 20% discount from the public offering price. Since the public offering price was $13.00, the price per share is $10.40. The offering price was determined on February 21, 2012, at which time the Convertible Note became a derivative security.
(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 Convertible Note 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.
