(1) On December 11, 2012, the Issuer completed its merger (the "Merger") with Valeant Pharmaceuticals International ("Valeant"), whereby the Issuer became a wholly owned subsidiary of Valeant, pursuant to an Agreement and Plan of Merger that was entered into on September 2, 2012 (the "Merger Agreement"). In accordance with the Merger Agreement, each share of common stock of the Issuer issued and outstanding immediately prior to the consummation of the Merger converted into a right to receive an amount in cash equal to $44.00 per share (the "Per Share Merger Consideration"), without interest. The amount of shares in Column 4 includes 2,311 restricted shares of common stock that also converted into a right to receive the Per Share Merger Consideration.
(2) In accordance with the terms of the Merger Agreement, each option to acquire shares of the Issuer (whether vested or unvested) that was outstanding immediately prior to the consummation of the Merger was cancelled in exchange for the right to receive an amount in cash equal to the product of the number of shares of Issuer common stock subject to the option and the excess, if any, of the Per Share Merger Consideration over the exercise price per share of each respective award, less any required withholding taxes. This award had fully vested prior to the consummation of the Merger.
(3) In accordance with the terms of the Merger Agreement, each option to acquire shares of the Issuer (whether vested or unvested) that was outstanding immediately prior to the consummation of the Merger was cancelled in exchange for the right to receive an amount in cash equal to the product of the number of shares of Issuer common stock subject to the option and the excess, if any, of the Per Share Merger Consideration over the exercise price per share of each respective award, less any required withholding taxes. This award was fully unvested prior to the consummation of the Merger.
