Sinovac Biotech Ltd. Retains Segue Ventures, LLC for Investor Relations and Public Relations

BEIJING--(BUSINESS WIRE)--June 2, 2005--Sinovac Biotech Ltd. ("Sinovac") ("the Company") (AMEX:SVA - News) announced today that it has retained the United States firm of Segue Ventures, LLC ("Segue") to provide investor relations and public relations services in North America.

Dr. Weidong Yin, President and CEO of Sinovac said, "There are two main purposes to the agreement with Segue. The purpose of Investor Relations is to accurately characterize Sinovac to the private and institutional investment community, and to provide a means for investors to communicate with the Company. Public Relations has a separate, yet complimentary purpose; to promote public awareness of Sinovac's exceptional qualities and potential."

Mr. Craig H. Bird is President of Segue, and a long-term investor in Sinovac. He has already begun the transition of responsibilities, and expects to have them completed by June 30, 2005. During the transition period, Mr. Bird traveled to Beijing where Sinovac educated him on all major areas of business and technology operations, agreements, and strategies. There were in-depth briefings, meetings with key personnel, and facility tours.

Sinovac and Segue have outlined a strategy that will lead to: fair market valuations for Sinovac's stock, opportunities to access inexpensive capital, a reasonable level of liquidity of its shares, and knowledgeable investors who share Sinovac's business and humanitarian vision. The investment community is a large one, therefore the investor relations strategy calls for actively engaging: institutional investors, private shareholders, investment analysts, and lenders.

Sinovac's share price is primarily a result of the market's expectations of future performance. This expectation results from many sources; such as analyst forecasts, company's statements, press reports and sector performance. Segue will endeavor to manage these expectations so they stay consistent with reality.

Furthermore, Segue will systematically communicate accurate messages about Sinovac's; quality of management; business performance; financial solvency; market potential; and business strategy, including achievements, future prospects, and growth predictions. After a week of extensive education at Sinovac, Mr. Bird commented, "Sinovac has a brilliant future. It is a superior company, with effective leadership and great business prospects. Segue will support Sinovac's expansion strategy by providing properly conceived and orchestrated investor and public relations service programs that reflect the same quality, skills and drive as Sinovac."

As Dr. Yin reviewed the IR and PR strategies, and the transition plan, he remarked, "I am confident in Craig's ethics, competence, commitment, and energy. He understands Sinovac and possesses the characteristics we desire to facilitate our growth and reputation as a public company." Mr. Bird purchased 400,000 shares of restricted stock through the Company's first private placement and over 150,000 shares on the open market since then.
