Santa Barbara, Calif., December 15, 2005—Inamed Corporation (Nasdaq: IMDC) announced today that its Board of Directors has unanimously approved the definitive Agreement and Plan of Merger (the “Merger Agreement”) between Inamed and Allergan previously executed and delivered by Allergan on December 6, 2005. However, Inamed has not yet signed the Merger Agreement. This approval was conducted in accordance with the terms of the irrevocable offer letter delivered to Inamed by Allergan on December 6, 2005.

Inamed has taken the steps required to comply with the terms of the irrevocable offer letter, including the provision of due diligence information regarding Juvederm and the delivery of disclosure schedules to the Merger Agreement. Under that irrevocable offer letter, Inamed has the ability to sign the previously negotiated and disclosed Merger Agreement with Allergan, upon receipt of notice from Allergan that Allergan is satisfied with its limited due diligence investigation of Juvederm and Inamed’s definitive disclosure schedules to the Merger Agreement.

The terms of Allergan’s exchange offer for all outstanding shares of Inamed common stock are described in Allergan’s Schedule TO filed with the Securities and Exchange Commission on December 12, 2005. Inamed intends to file an amended statement on Schedule 14D-9 with the Securities and Exchange Commission today reflecting the approval of the Merger Agreement.
