Item 1.01 Entry into a Material Definitive Agreement.

On December 11, 2006, Indevus Pharmaceuticals, Inc. (“Indevus”), Hayden Merger Sub, Inc. (“Merger Sub”), a wholly-owned subsidiary of Indevus, and Valera Pharmaceuticals, Inc. (“Valera”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which Indevus will acquire Valera. The following description of the Merger Agreement does not purport to be a complete description and is qualified in its entirety by reference to the full text of the Merger Agreement, which is attached hereto as Exhibit 2.1 and is incorporated herein by reference.

Under the terms and subject to the conditions set forth in the Merger Agreement, which has been unanimously approved by the boards of directors of Indevus, Merger Sub and Valera, Merger Sub will be merged with and into Valera (the “Merger”), the separate corporate existence of Merger Sub will cease and Valera will continue as the surviving corporation of the Merger and as a wholly-owned subsidiary of Indevus. The merger is intended to qualify as a tax-free reorganization under the Internal Revenue Code of 1986, as amended, and be tax-free to Indevus and to Valera stockholders.

Pursuant to the Merger Agreement, upon the closing of the Merger, each share of common stock of Valera outstanding immediately prior to the closing of the Merger (other than shares held by Valera or Indevus or any stockholders who properly exercise dissenters’ rights under Delaware law), will automatically be converted into the right to receive a number of shares of Indevus common stock equal to $7.75 divided by the volume weighted average of the closing prices of Indevus common stock during the 25 trading days ending on the fifth trading day prior to the date of the Valera stockholders’ meeting to consider the Merger (the “Indevus Common Stock Value”). The exchange ratio is subject to a collar such that if the Indevus Common Stock Value falls outside of the collar the exchange ratio will become fixed. If the Indevus Common Stock Value is greater than $8.05, then the exchange ratio will be .9626, and if it is less than $6.59, then the exchange ratio will be 1.1766. Cash will be paid in lieu of fractional shares.

In addition to the shares of Indevus common stock as provided above, subject to the terms and conditions set forth in contingent stock rights agreements to be entered into between Indevus and a Rights Agent, each outstanding share of Valera common stock will be converted into the right to receive one contingent stock right (“CSR”) for each of three Valera products in development–Supprelin-LA, ureteral stent and VP003 (Octreotide implant)–convertible for $1.00, $1.00 and $1.50, respectively, worth of Indevus common stock upon Indevus receiving an approval letter from the U.S. Food and Drug Administration (“FDA”) with respect to such product (and, in the case of Supprelin-LA, Indevus possesses a specified amount of inventory of commercially saleable units of Supprelin-LA). If FDA approval (and the commercially saleable unit requirement in the case of Supprelin-LA) is not achieved within three years of closing in the case of Supprelin-LA and within five years of closing in the case of ureteral stent and VP003 (Octreotide implant), the respective CSRs will expire.

Each option to purchase shares of Valera common stock outstanding upon the closing of the Merger will be cancelled in exchange for the right to receive the following consideration:

•

Option holders that consent to the proposed treatment of Valera options will receive the following: (a) options with exercise prices below $7.75 per share will receive (i) at closing, Indevus common stock based on the spread between $7.75 and the exercise price of the option and (ii) Indevus’ unfunded and unsecured promise to issue, in the future, the number of shares of Indevus common stock that would have been issuable had option holders received CSRs; and (b) options with exercise prices of $7.75 or more will receive Indevus’ unfunded and unsecured promise to issue, in the future, the number of shares of Indevus common stock determined by a formula based on the equivalent of the CSRs, net of the option exercise price exceeding $7.75.

•

Option holders that do not provide consent to the proposed treatment of Valera options will receive the following: (a) options with exercise prices below the closing price of Valera common stock on the trading day immediately preceding the closing of the Merger will receive shares of Indevus common stock based on the spread between Valera’s closing stock price on the trading day immediately preceding the effective time and the exercise price of the option, but will not receive CSRs; and (b) options with exercise prices equal to or greater than the closing price of Valera common stock on the trading day immediately preceding the closing of the Merger will not be entitled to any consideration upon cancellation.

Completion of the Merger is subject to various customary conditions, including, among others, (i) requisite approvals of Indevus and Valera stockholders, (ii) effectiveness of the registration statement for the Indevus securities to be issued in the Merger, (iii) expiration or termination of the applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and (iv) absence of any governmental action challenging or seeking to prohibit the Merger.

The Merger Agreement contains customary representations, warranties and covenants of Indevus and Valera, including, among others, covenants (i) to conduct their respective businesses in the ordinary course during the interim period between the execution of the Merger Agreement and completion of the Merger, (ii) not to engage in certain kinds of transactions during this interim period, (iii) to hold a stockholder meeting to put these matters before their stockholders for their consideration and (iv) to use their reasonable best efforts to take all actions necessary to obtain approval under all applicable antitrust laws. Valera is also subject to a “no shop” restriction on its ability to solicit alternative acquisition proposals, provide information and engage in discussion with third parties, except under limited circumstances to permit Valera’s board of directors to comply with its fiduciary duties. Indevus is also subject to a covenant to use commercially reasonable efforts to develop, in the ordinary course, Supprelin-LA for a period of three years and ureteral stent and VP003 (Octreotide implant) for a period of five years.

The Merger Agreement contains certain termination rights for both Indevus and Valera and further provides that, upon termination of the Merger Agreement under specified circumstances, Valera or Indevus may be required to pay the other a termination fee of $5,000,000. The Merger Agreement also provides that under specified circumstances where the termination fee is not otherwise payable, Valera or Indevus may be required to reimburse the non-terminating party for

up to $3,000,000 of reasonable out-of-pocket expenses. Any expenses paid by Valera or Indevus will be credited against the termination fee if the termination fee subsequently becomes payable by that party.

The Merger Agreement, which has been included to provide investors with information regarding its terms, contains representations and warranties of each of Indevus and Valera. The assertions embodied in those representations and warranties were made for purposes of the Merger Agreement and are subject to qualifications and limitations agreed by the respective parties in connection with negotiating the terms of the Merger Agreement. In addition, certain representations and warranties were made as of a specific date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for purposes of allocating risk between the respective parties rather than establishing matters as facts. Investors should read the Merger Agreement together with the other information concerning Indevus that Indevus publicly files in reports and statements with the Securities and Exchange Commission.

Voting Agreements

In connection with the Merger Agreement, Indevus and Hayden Merger Sub, Inc. have entered into voting agreements (each a “Voting Agreement”) with certain affiliated funds of Sanders Morris Harris, Inc and with Psilos Group Partners II-S, L.P. (each a “Stockholder”) collectively owning approximately 41.4% of Valera’s outstanding shares as of December 11, 2006. The following description of the Voting Agreements do not purport to be a complete description and is qualified in its entirety by reference to the full texts of each Voting Agreement, which are attached hereto as Exhibits 99.1 and 99.2 and are incorporated herein by reference.

Pursuant to each Voting Agreement, the Stockholder agreed to vote its shares in favor of the Merger and against any transaction or other action that would interfere with the Merger. The Stockholder’s agreement to vote its shares of Valera common stock as described above is subject to limitations if the Valera board of directors changes its recommendation with respect to the Merger. Under such circumstances, the Stockholder is required to vote in favor of the Merger (or against another transaction) only a number of shares equal to half of the outstanding shares of Valera common stock that it owns, with the remaining half of its shares required to be voted in the same proportion as all other shares of Valera common stock not beneficially owned by any of the Stockholders. The Voting Agreement also prohibits the Stockholder from taking various actions that could be expected to facilitate a competing takeover proposal or otherwise be inconsistent with or violative of the provisions of the Voting Agreement.

On December 12, 2006, Valera posted on its website a presentation to investors and fact sheet with respect to the proposed business combination transaction with Indevus. A copy of each of the presentation to investors and fact sheet is attached hereto as Exhibits 99.3 and 99.4.
