WOODCLIFF LAKE, N.J., Dec. 2 /PRNewswire-FirstCall/ -- Barr Pharmaceuticals, Inc. ("Barr") , Organon USA Inc. and Organon (Ireland) Ltd. ("Organon"), business units of Akzo Nobel NV , and Savient Pharmaceuticals, Inc. ("Savient") today announced that Barr and its subsidiaries have finalized an agreement to acquire the exclusive rights to Organon's Mircette(R) (Desogestrel/Ethinyl Estradiol) oral contraceptive product. The agreement terminates the ongoing patent litigation regarding Barr's generic version of Mircette(R), which the Company markets under the trade name Kariva(R).

On June 30, 2005, Barr and Organon filed the Letter of Intent with the Federal Trade Commission ("FTC") pursuant to the Hart Scott Rodino Antitrust Improvements Act. On August 1, 2005, the FTC issued a second request for information regarding the proposed transaction. On November 16, 2005, the FTC's review period, which had been voluntarily extended by Barr and Organon, expired without the FTC having initiated any action to stop the acquisition.

Barr's Duramed Pharmaceuticals subsidiary will promote Mircette(R) to female healthcare practitioners utilizing its recently expanded Specialty Sales Force.

Mircette(R) is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception. Mircette(R) is available in a 28-tablet regimen that represents a combination of desogestrel/ethinyl estradiol and ethinyl estradiol.
