(1) Ipsen S.A., a 'societe anonyme' organized under the laws of France ("Ipsen") and Suraypharm, a 'societe par actions simplifiee' organized under the laws of France ("Suraypharm"), may be deemed to have acquired beneficial ownership of shares of the Common Stock of the Issuer (the "Securities"), pursuant to certain Voting Agreements, dated as of July 18, 2006 (the "Voting Agreements"), between Ipsen, Suraypharm and certain stockholders of the Issuer (the "Tercica Stockholders").
(2) Pursuant to Rule 13d-4 of the Act, Ipsen and Suraypharm disclaim beneficial ownership of such Securities. Pursuant to Rule 16a-1(a)(4) of the Act, nothing in this filing shall be deemed an admission that Ipsen and Suraypharm are, for purposes of Section 16 of the Act or otherwise, the beneficial owner of the Securities covered by the Voting Agreements. For a description of the Voting Agreements, see the Schedule 13D filed by Ipsen and Suraypharm with the United States Securities and Exchange Commission on the date hereof (the "Ipsen 13D").
(3) The Ipsen 13D contains a description of the relationship among Ipsen, Suraypharm and the Tercica Stockholders under the Voting Agreements but is not an admission by Ipsen and Suraypharm of the existence of a group for purposes of Section 13(d)(3) or Section 13(g)(3) of the Act and Rule 13d-5(b)(1) thereunder or Section 16 of the Act and the rules thereunder. Ipsen and Suraypharm do not have or share a pecuniary interest in the Securities covered by the Voting Agreements for purposes of Rule 16a-1(a)(2) under the Act.

Information regarding Ipsen's majority shareholder, Mayroy, S.A., is provided in Item 2 of the Ipsen 13D.  Such information does not constitute an admission that such person is a direct or indirect beneficial owner of the Issuer's Common Stock.
