Allergan, Inc. (NYSE: AGN) (“Allergan”) and MAP Pharmaceuticals, Inc. (NASDAQ: MAPP) (“MAP”) today announced that the Federal Trade Commission has granted early termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), with respect to the tender offer for all of the outstanding shares of common stock of MAP by Groundhog Acquisition, Inc. (“Purchaser”), a wholly-owned subsidiary of Allergan.

As previously announced, on January 31, 2013, Purchaser initiated a tender offer to purchase all outstanding shares of common stock of MAP for $25.00 per share, net to the seller in cash, without interest and less any applicable withholding taxes. The tender offer is being made pursuant to an Agreement and Plan of Merger, dated as of January 22, 2013, by and among Allergan, Purchaser and MAP (the “Merger Agreement”).

The termination of the HSR Act waiting period satisfies one of the conditions to the completion of the tender offer. Completion of the tender offer remains subject to other customary conditions as set forth in the Offer to Purchase filed by Purchaser and Allergan with the U.S. Securities and Exchange Commission (the “SEC”) on January 31, 2013, including the tender of at least a majority of the outstanding shares of common stock of MAP on a fully diluted basis. The tender offer and withdrawal rights are scheduled to expire at 12:00 midnight, New York City time, on the night of February 28, 2013, unless extended in accordance with the terms of the Merger Agreement and applicable rules and regulations of the SEC.
