Reference is hereby made to the Schedule 13D filed with the Securities and Exchange Commission on July 30, 2012 (the “Schedule 13D”). Terms defined in the Schedule 13D are used herein as so defined.

The following items of the Schedule 13D are hereby amended as follows:

ITEM 4. PURPOSE OF TRANSACTION.

On November 17, 2014 (the “Closing Date”), Actavis W.C. Holding Inc. (“Parent”) completed its tender offer and acquisition of all of the shares of Common Stock of the Issuer (the “Tender Offer and Merger”) at a purchase price of (a) $23.00 per share, net to the seller in cash, without interest and less any applicable withholding taxes (the “Cash Consideration”) plus (b) one contractual contingent value right per Share (each, a “CVR”), which represents the right to receive contingent payments of up to $5.00 in cash in the aggregate, if any, without interest and net of applicable withholding taxes, if specified milestones are achieved (the Cash Consideration plus one CVR, referred to herein collectively as the “Offer Price”). Also on the Closing Date, (i) each outstanding Issuer stock option fully vested and automatically became cancelled and terminated as of the Closing Date and the holder thereof became entitled to receive (a) an amount in cash, equal to the product of (1) the number of shares of common stock of the Issuer underlying such option multiplied by (2) the excess, if any, of the Cash Consideration over the exercise price per share of such option and (b) one CVR for each share underlying such Issuer stock option outstanding immediately prior to the Effective Time, in each case without interest and less the amount of any tax withholding, and (ii) each outstanding share of Issuer restricted stock fully vested and the restrictions lapsed, and each such share of restricted stock became cancelled and converted into the right to receive the Offer Price, in each case without interest and less the amount of any tax withholding.

All 1,907,064 shares of Common Stock, 1,216 shares of restricted stock and stock options to purchase 8,575 shares of Common Stock that were beneficially owned by the Reporting Persons were sold or cancelled and converted into the right to receive the portion of the Offer Price as described above in connection with the closing of the Tender Offer and Merger.

ITEM 5. INTEREST IN SECURITIES OF THE ISSUER.

(a), (b), (c), (d) and (e):

As of November 17, 2014, the Reporting Persons beneficially owned 0 shares of Common Stock, as a result of the Tender Offer and Merger, and have ceased to be the beneficial owner of more than five percent of the Issuer’s Common Stock.
