Item 8.01 Other Events.

     On March 2, 2010, Medicis Pharmaceutical Corporation (the “Company”) filed a request with the U.S. Food and Drug Administration (“FDA”) to list U.S. Patent No. RE41,134 (the “’134 Reissue Patent”) in the FDA’s Approved Drug Products with Therapeutic Equivalence Evaluations (the “Orange Book”). The ’134 Reissue Patent covers the Company’s product ZIANA^®, a prescription topical gel indicated for the treatment of acne, and specifically claims aqueous topical tretinoin compositions that include polyacrylic acid and antioxidant elements. The ’134 Reissue Patent was issued by the U.S. Patent and Trademark Office (“USPTO”) on February 16, 2010 as a result of an application for reissue of U.S. Patent No. 5,721,275 (the “’275 Patent”), which also covers ZIANA. The Company has rights to the patents pursuant to a license agreement with the owner of the patents. Upon the USPTO’s issuance of the ’134 Reissue Patent, the ’275 Patent was automatically surrendered under applicable law. The Company has also requested that the FDA delist the ’275 Patent from the Orange Book upon the listing of the ’134 Reissue Patent. The expiration date for the ’134 Reissue Patent is in 2015.
