In Separate Purchase Agreement, Par Acquires All Rights to ANDA for Testosterone Gel 1% from Paddock Laboratories, Inc.

Par Branded Sales Force to Co-promote AndroGel

SPRING VALLEY, N.Y., Sept. 13 (HSMN NewsFeed) -- Par Pharmaceutical Companies, Inc. (NYSE: PRX ) today announced that it has acquired from Paddock Laboratories, Inc. all rights to the Abbreviated New Drug Application (ANDA) for testosterone gel 1%. Testosterone gel 1% is the generic version of AndroGel®, which is marketed in the U.S. by Unimed Pharmaceuticals, Inc., a wholly-owned subsidiary of Solvay Pharmaceuticals, Inc. Par subsequently entered into a settlement and license agreement with Solvay Pharmaceuticals that resolves patent litigation related to AndroGel, eliminating the inherent uncertainty and costs of litigation. The settlement and license agreement terminates all ongoing litigation involving Unimed Pharmaceuticals, Laboratories Besins Iscovesco and Paddock Laboratories, Inc. It also permits Par to launch its generic version of the product no later than February 28, 2016, assuring Par's ability to market a generic version well before the expiration of the patents at issue.

Par also entered into a separate extended-reach agreement with Solvay Pharmaceuticals that provides for Par's branded sales force to co-promote AndroGel for a period of six years. AndroGel is indicated for replacement therapy in males for conditions associated with a deficiency or absence of endogenous testosterone.

"Par is very pleased to co-promote the most widely prescribed testosterone therapy in the U.S.," said John A. MacPhee, president, Branded Products Division. "This agreement provides Par with its third branded product to promote and we look forward to a very successful collaboration with Solvay Pharmaceuticals."

Purchase Agreement

Under the terms of its purchase agreement with Paddock, Par paid $6 million for all rights to Paddock's ANDA for testosterone gel 1%, including all intellectual property associated with the product. Paddock filed an ANDA with the U.S. Food and Drug Administration in May 2003 seeking marketing clearance for its generic version of AndroGel. In July 2003, Par entered into a licensing agreement with Paddock to market the product in the U.S.

Settlement and License Agreement

In accordance with the settlement and license agreement, pending patent litigation between Unimed, Laboratories Besins Iscovesco and Paddock in the United States District Court for the Northern District of Georgia, Atlanta Division has been dismissed. Solvay Pharmaceuticals will grant Par a non- exclusive license to market, sell and distribute a generic version of AndroGel beginning no later than February 26, 2016. This is more than four years prior to the expiration of U.S. Patent No. 6,503,894, which had been the subject of the litigation. As part of the settlement, Par admits that the patent is valid and enforceable and that Par infringes the patent.

Extended-Reach Agreement

Par also entered into an extended-reach agreement with Solvay Pharmaceuticals that provides for Par's branded sales force to co-promote AndroGel, as well as future versions of the product, for a period of six years. Par will commence pre-launch activities in the fourth quarter of 2006 and begin to co-promote AndroGel in the first quarter of 2007. As compensation for its marketing and sales efforts, Par will receive $10 million annually, paid quarterly, for the six-year period.
