Endo Pharmaceuticals Successfully Completes Tender Offer for Shares of Indevus

Pharmaceuticals and Announces Subsequent Offering Period

Chadds Ford, PA – February 23, 2009 – Endo Pharmaceuticals (NASDAQ: ENDP) today announced the successful completion of the tender offer by its wholly owned subsidiary, BTB Purchaser Inc., for all of the outstanding shares of common stock of Indevus Pharmaceuticals, Inc. (NASDAQ: IDEV). American Stock Transfer & Trust Company, the depositary for the tender offer, has advised Endo that, as of 5:00 p.m., New York City time, on February 20, 2009, the initial expiration of the tender offer, approximately 61,358,944 shares were validly tendered and not withdrawn in the tender offer, representing approximately 77.972% of Indevus’ issued and outstanding shares. All validly tendered shares have been accepted for payment and Endo will pay for all such shares promptly.

Endo also announced today that it would make available a subsequent offering period commencing immediately and expiring on February 27, 2009 at 5:00 p.m. New York City time for all Indevus shares not tendered into the offer prior to the initial expiration date. During the subsequent offering period, BTB will accept for payment and promptly pay for Indevus shares as they are tendered. Stockholders who tender shares during such period will receive the same $4.50 per Indevus share in cash and the contractual right to receive up to an additional $3.00 per Indevus share in cash payable upon achievement of certain regulatory and sales milestones as was paid to Indevus stockholders pursuant to the tender offer. Procedures for tendering shares during the subsequent offering period are the same as during the initial offering period with two exceptions: (1) shares cannot be delivered by the guaranteed delivery procedure and (2) pursuant to Rule 14d-7(a)(2) under the Securities Exchange Act of 1934, as amended, shares tendered during the subsequent offer period may not be withdrawn.

Endo and BTB reserve the right to extend the subsequent offering period in accordance with applicable law. After expiration of the subsequent offering period, BTB will acquire all of the remaining outstanding shares of Indevus common stock by means of a merger under Delaware law. As a result of the purchase of shares in the tender offer, BTB has sufficient voting power to approve the merger without the affirmative vote of any other Indevus stockholder. Following the merger, Indevus will become a wholly-owned subsidiary of Endo, and each share of Indevus’ outstanding common stock will be cancelled and converted into the right to receive the same consideration, without interest, received by holders who tendered in the tender offer. Thereafter, Indevus common stock will cease to be traded on the NASDAQ Stock Market.
