ITEM 1.01.  ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT.

Agreement and Plan of Merger

On June 4, 2008, Tercica, Inc. (the “Company”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Beaufour Ibsen Pharma, a société par actions simplifiée organized under the laws of France (“Parent”), and Tribeca Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger Sub”). Certain affiliates of Parent hold an aggregate of approximately 25.3% of the Company’s outstanding common stock. Under the terms of the Merger Agreement and subject to the satisfaction or waiver of the conditions therein, Parent will acquire, through the merger of Merger Sub with and into the Company (the “Merger”), all of the outstanding common stock of the Company not already held by Parent or its affiliates. As a result of the Merger, the Company will become a subsidiary of Parent.

At the effective time of the Merger (the “Effective Time”), each outstanding share of common stock of the Company, other than shares owned by Parent, Merger Sub or their respective affiliates, or by any stockholders who are entitled to and properly exercise appraisal rights under Delaware law, will be converted into the right to receive $9.00 per share in cash.

The Merger Agreement and the Merger were unanimously approved by the Company’s Board of Directors following recommendation and approval by a special committee of the Company’s Board of Directors comprised of three independent non-employee directors. The special committee was advised by independent legal and financial advisors.

The obligations of the parties to consummate the Merger are conditioned upon, among other things, the adoption of the Merger Agreement by the stockholders of the Company, regulatory approvals and other customary closing conditions.

In connection with the execution of the Merger Agreement, certain stockholders of the Company, including certain officers and members of the Company’s Board of Directors, entered into voting agreements pursuant to which they have agreed to, among other things, vote in favor of the adoption of the Merger Agreement (such agreements, the “Voting Agreements”).

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to this Current Report on Form 8-K and incorporated herein by reference. The Merger Agreement has been included to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company or Parent. The Merger Agreement contains representations and warranties the parties thereto made to and solely for the benefit of each other. The assertions embodied in those representations and warranties are qualified by information in a confidential disclosure letter that the Company delivered in connection with signing the Merger Agreement. Accordingly, investors and security holders should not rely on the representations and warranties as characterizations of the actual state of facts, since they were only made as of the date of the Merger Agreement and are modified in important part by the underlying disclosure letter. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

On June 4, 2008, the Company issued a press release regarding the execution of the Merger Agreement. The press release is filed as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Additional Information about the Merger and Where to Find It

The Company plans to file a proxy statement with the Securities and Exchange Commission relating to a solicitation of proxies from its stockholders in connection with a special meeting of stockholders of the Company to be held for the purpose of voting on the adoption of the merger agreement relating to the proposed transaction. The Company and Parent also intend to file a transaction statement on Schedule 13E-3 with the SEC relating to the Merger. BEFORE MAKING ANY VOTING DECISION WITH RESPECT TO THE PROPOSED TRANSACTION,

ITEM 3.03.  MATERIAL MODIFICATION TO RIGHTS OF SECURITY HOLDERS.

On June 4, 2008, the Company entered into an Amendment No. 1 to Rights Agreement, by and between Computershare Trust Company, N.A. (the “Rights Agent”) and the Company (the “Amendment”). The Amendment amends the terms of the Rights Agreement, dated as of October 13, 2006, by and between the Company and the Rights Agent (the “Rights Agreement”). The Amendment was entered into in order to prevent the Merger Agreement, the Voting Agreements, the Merger or the consummation of any other transactions contemplated by the Merger Agreement or the Voting Agreements from triggering the distribution and/or exercise of the Rights (as defined in the Rights Agreement). The Amendment provides that, among other things, (i) no Distribution Date (as defined in the Rights Agreement), no Transaction (as defined in the Rights Agreement) and no Shares Acquisition Date (as defined in the Rights Agreement) will be deemed to have occurred as a result of, among other things, the approval, execution and delivery of the Merger Agreement or the Voting Agreements, or the consummation of the Merger or any other transactions contemplated thereby; (ii) no party to the Merger Agreement or the Voting Agreements (including such party’s affiliates and associates) will be or become an Acquiring Person (as defined in the Rights Agreement) or an Interested Party (as defined in the Rights Agreement) as a result of, among other things,

the approval, execution and delivery of the Merger Agreement or the Voting Agreements, or the consummation of the Merger or any other transactions contemplated thereby; and (iii) the Rights will expire and the Final Expiration Date (as defined in the Rights Agreement) will occur, immediately prior to the Effective Time.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, which is filed as Exhibit 4.1 to this Current Report on Form 8-K and incorporated herein by reference.
