Perrigo Company Announces Collaborative Agreement for Generic Topical Products With Pentech Pharmaceuticals

ALLEGAN, Mich., May 21 -- Perrigo Company (Nasdaq: PRGO; TASE) today announced that it has entered into a collaborative agreement with Cobrek Pharmaceuticals, a newly formed entity of Pentech Pharmaceuticals Inc., a privately owned company that specializes in the research and development of niche generic dosage forms. Pentech will contribute its ANDA filing for a generic equivalent to Luxiq® foam, a $34 million branded pharmaceutical product, to the agreement. Perrigo will contribute two of its early stage generic topical pipeline products. The parties will share the development costs and profits generated by these products, with Perrigo being the exclusive distributor.

Pentech filed its ANDA for Luxiq foam containing a Paragraph IV Certification with the U.S. Food & Drug Administration and notified Connetics, the New Drug Application holder for the brand product. On November 6, 2007, Connetics filed suit alleging patent infringement in the United States District Court for the Northern District of Illinois to prevent Pentech from proceeding with the commercialization of its product. The lawsuit formally initiated the patent process under the Hatch-Waxman Act. Pentech believes that it is the first to file an ANDA with a Paragraph IV certification against Luxiq and Perrigo believes that it will be the first company to market this product.

Perrigo will also invest $12.5 million in cash in Cobrek in exchange for a minority ownership position. Pentech will contribute to Cobrek all of its interests in current and future ANDA filings including a potential first-to-file on a generic version of Hectorol (Doxercalciferol).

Commenting on the announcement, Perrigo Chairman and Chief Executive Officer, Joe Papa, stated, "Cobrek will utilize its proven ability to develop niche generic products while capitalizing on Perrigo's marketing and distribution capabilities. This strategic collaborative agreement and investment enhances our existing U.S. product portfolio and future pipeline, demonstrating our on-going commitment to the generic prescription dermatological space. We believe that these new and future products will expand Perrigo's leadership position in this category and provide an opportunity for us to improve returns on one of our core businesses. We look to identify more such opportunities in the future."

Pentech Pharmaceuticals, formed in 1993, is a prescription pharmaceuticals development company, whose strategy is to seek out special situations in the pharmaceutical industry, paying particular attention to the changing healthcare requirements of an aging population. Special emphasis is placed on finding products and market niches which offer strong revenue potential, limited competitive pressure, and extended product life cycles. As a rule, Pentech limits its activities to the validation of its products through internally conducted scientific, market and legal research, while seeking partnerships with larger, more established companies such as Perrigo to execute clinical, marketing and manufacturing functions. Prior to the transaction described in this release, Pentech's past successes under its strategy included apomorphine HCL, a proprietary erectile dysfunction drug licensed to TAP, and generic Paxil, the subject of a joint manufacturing and marketing arrangement with Par Pharmaceuticals.
