Penwest Pharmaceuticals

Penwest is a specialty pharmaceutical company dedicated to bringing to the marketplace innovative products that help improve the lives of patients. The Company's goal is to identify, develop and commercialize prescription products that address unmet medical needs, primarily for diseases of the nervous system. At the core of this strategy, Penwest applies drug delivery technologies, including its own proprietary technologies, to new and existing compounds to enhance their therapeutic profiles. The launch by Endo Pharmaceuticals in mid-2006 of Opana(r) ER (oxymorphone hydrochloride extended-release tablets) formulated with the Company's TIMERx(r) extended release delivery technology demonstrates the execution of this strategy and the value of the Company's TIMERx(r) technology. The Company is currently applying its expertise to a pipeline of potential products that are in various stages of development. The Company intends to commercialize these products independently or through third party alliances.
