The Company Files Suit Against Stiefel Laboratories, Inc.

     On July 28, 2010, Medicis Pharmaceutical Corporation (the “Company”) filed suit against Stiefel Laboratories, Inc., a subsidiary of GlaxoSmithKline plc (“Stiefel”), in the United States District Court for the Western District of Texas — San Antonio Division seeking a declaratory judgment that the manufacture and sale of Stiefel’s acne product VELTIN™ Gel, which was recently approved by the U.S. Food and Drug Administration (“FDA”), will infringe one or more claims of the Company’s U.S. Patent No. RE41,134 (the “’134 Patent”) covering the Company’s product ZIANA^® Gel, a prescription topical gel indicated for the treatment of acne that was approved by the FDA in November 2006. The ’134 Patent is listed in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (Orange Book) and expires in February 2015. The Company has rights to the ’134 Patent pursuant to an exclusive license agreement with the owner of the patent. The relief requested by the Company in the lawsuit includes a request for a permanent injunction preventing Stiefel from infringing the ’134 Patent by engaging in the commercial manufacture, use, importation, offer to sell, or sale of any therapeutic composition or method of use covered by the ’134 Patent, including such activities relating to VELTIN™, and from inducing or contributing to any such activities.
