Viropro Inc.: An Emerging Player in the Production and Technology Transfer of Therapeutic Proteins

A World Market Worth 15 Billion Dollars U.S.

MONTREAL, May 9, 2006 (PRIMEZONE) -- Viropro Inc. ("Viropro" or "The Company") is rapidly solidifying its reputation as an international expert in the production and set-up of technology transfers of therapeutic proteins to pharmaceutical companies for the treatment of diseases such as cancer, diabetes, hepatitis and multiple sclerosis. The industrial production is destined for emerging regions of the world with unmet needs such as South America, Asia and Africa.

Viropro is entering this vital market with a solid technological platform, an experienced management team in the development of international businesses and an innovative approach in the therapeutic proteins field. By offering its partners integrated solutions and understanding the niche markets it serves, Viropro is positioning itself in a market worth 15 billion dollars U.S. for the 10 biggest selling proteins which no longer have market exclusivity.

With this significant market potential, the company intends to materialize future agreements which will further demonstrate its know-how and technological expertise. Viropro provides pharmaceutical companies access to robust revenues and profitable potential markets. Viropro offers pharmaceutical partners new expertise and new technological platform at a competitive price from which these companies will manufacture and bring to market new therapeutic proteins. It is presently in negotiations with several South American and African pharmaceutical companies with the objective of signing agreements for marketing and technological partnerships in the near future. Announcements on this subject should be made over the coming weeks.

Viropro relies on a business model built on recurring sales revenues and short-term profitability scenario. Viropro intends to maintain a light, flexible and low over-head cost structure by outsourcing services for non-core business activities.

The management has a proven track record with numerous achievements in life sciences and a solid international network built with life science industry leaders, Public, Para-Public and Governmental organizations as well as health and regulatory agencies.
