NEWPORT BEACH, Calif. – October 8, 2002 – The TriZetto(R) Group, Inc. (Nasdaq:TZIX) announced today that it has been ranked second in Deloitte and Touche's prestigious "Fast 50" program for the Orange County/San Diego area.

The ranking, which lists the 50 fastest growing technology companies in the area, is based on the percentage of growth in fiscal year revenues from 1997 to 2001. According to the calculation used by Deloitte & Touche, TriZetto increased revenues by 8,561 percent over this five-year period, from $2.5 million to $218 million.

Under the leadership of founder, Chairman and CEO Jeffrey H. Margolis, TriZetto has grown rapidly through a combination of organic growth and strategic acquisitions. Today, TriZetto software is used to process medical transactions for over 100 million insured individuals in the U.S. TriZetto is the largest provider of outsourced, Internet-based software services in healthcare, as well as the largest provider of packaged software and Internet platforms for health plans.

"Our rapid growth is the result of our 100 percent focus on healthcare and our strategy of providing a single, comprehensive source of technology and services to our customers," Margolis said. "And like any fast-paced, young company, our growth reflects the energy, enthusiasm and commitment of our management team and employees. The TriZetto team worked countless hours to earn this ranking, in a notoriously difficult technology market. Equally important, in the process we created innovative, quality products and services for our customers. We appreciate Deloitte & Touche's recognition of our success."

To qualify for the "Fast 50," companies must have had operating revenues of at least $50,000 in 1997 and $1,000,000 in 2001, must be public or private companies headquartered in North America, and be "technology companies" defined as companies that own proprietary technology which contributes to a significant portion of the company's operating revenues or devotes a high percentage of effort to research and development of technology.

TriZetto counts some of the country's premier healthcare and corporate organizations as customers, including nearly one-third of the nation's Blue Cross and Blue Shield organizations. Larger customers include: Anthem Blue Cross Blue Shield, Humana, Blue Cross Blue Shield of Michigan, Mutual of Omaha, PacifiCare Behavioral Health and The Regence Group.

"To rank on the Deloitte & Touche Technology 'Fast 50,' companies must have phenomenal revenue growth in a five-year period. TriZetto has proven to be one of the fast-growth success stories in Orange County and San Diego, and we applaud their success and vision," said Fred Poska, partner, Technology, Media & Telecommunications group, Orange County office of Deloitte & Touche.

With its regional "Fast 50" selection, TriZetto is automatically entered in the Deloitte & Touche Technology "Fast 500" program, which ranks North America's top-500 fastest growing technology companies. The results of the national ranking will be announced later this month.
