Agreement Joins Innovator in Cholesterol Personal Health Management

With World Renowned Heart Disease Program

HAYWARD, Calif.--(BUSINESS WIRE)--July 20, 2000

Cholestech Corporation (Nasdaq:CTEC), a leading provider of cholesterol diagnostic technology and screening services, announced today the association of WellCheck.com, Cholestech's new eBusiness, and the Stanford Center for Research in Disease Prevention (Stanford). Cholestech and Stanford will collaborate to help people reduce the risks of high cholesterol, which studies show to be one of the top risk factors for heart disease--the number one killer of Americans.

WellCheck.com (www.wellcheck.com) offers an extensive personal health management program to empower individuals to manage their high cholesterol on a daily basis. The currently-available online resource is a new business for Cholestech, which also manufactures and markets the Cholestech LoDoX(R) System for identifying and monitoring high cholesterol levels, and provides cholesterol testing services through its WellCheck(TM) business.

"We go beyond most health care information sites on the internet by focusing on helping individuals manage their risk of heart disease on a day-to-day basis," said Jeffrey Aroy, Chief Operating Officer of WellCheck.com. "We have developed a powerful set of interactive tools that are highly personalized to the individual. Stanford's research is the medical engine that drives these tools. We are excited to work together with Stanford's Center for Research in Disease Prevention to bring their eminent heart disease program to more people through an new and innovative interactive medium."

The Stanford Center for Research in Disease Prevention is an internationally recognized leader in research in preventing chronic diseases, including heart disease. Stanford has played a pivotal role in establishing national guidelines for chronic disease prevention and treatment and has developed world-renowned educational and behavioral programs to promote heart-healthy lifestyle choices.

"We're enthusiastic about this relationship," says Wes Alles, Ph.D., Director of the Stanford Health Improvement Program. "Our primary mission is disease prevention. Cholestech has been a dynamic leader in providing tools to help people understand their risks of disease related to cholesterol. The combination of information based on Stanford Center for Research in Disease Prevention research with Internet technology provided through WellCheck.com, and testing through WellCheck, will hopefully encourage more people to favorably manage their cholesterol."

Warren E. Pinckert II, President and Chief Executive Officer of Cholestech, agrees. "Our partnership with Stanford is one of the foundation stones upon which we are building our personal health management program for the consumer. WellCheck will run ongoing testing programs in retail venues, special events, and corporate facilities. These test events will refer members to WellCheck.com, our web site. WellCheck.com members will be able to track test results easily over time and use the on-line tools developed with Stanford to improve their cholesterol levels and overall health."

WellCheck.com is available to the general public at www.wellcheck.com.
