NEWPORT BEACH, Calif. – January 3, 2002 – The TriZetto(R) Group, Inc. (Nasdaq: TZIX) has signed a $32 million agreement with M*Plan, a 178,000-member health plan based in Indianapolis, Indiana. Under the six-year contract, TriZetto will host and manage its Erisco's Facets(R) administrative software for M*Plan and assume responsibility for processing medical claims, enrollment and other transactions. For a predictable monthly fee, M*Plan will have access to Facets technology through TriZetto's main data center in Greenwood Village, Colorado. The Facets system will provide processing capability for essential health plan functions, including enrollment, member eligibility, benefits tracking, billing and claims.

The agreement underscores TriZetto's ability to deliver its leading applications on a licensed or hosted basis, according to the customer's needs. TriZetto's acquisition of Erisco in the fall of 2000 allowed TriZetto to combine its software hosting expertise with Facets' deep functionality and industry-wide acceptance. Today, TriZetto is a single source of information technology solutions, providing hosted applications, enterprise software, e-business applications, consulting, and outsourcing services.

"This agreement gives M*Plan the premier managed care administration system on the market with the advantages of TriZetto's hosted delivery model, including faster implementation time, ongoing technical support, and an attractive, predictable pricing structure," said Alex Slabosky, president of M*Plan. "The hosted option clearly made the most sense for us."

"It's rewarding to see new TriZetto customers, as well as existing Facets license customers, moving toward the hosted Facets option," said Dan Spirek, president of TriZetto's Business Solutions unit. "The benefits include lower up-front and ongoing costs, as well as upgrades and guaranteed performance levels. TriZetto benefits as well, from the predictable monthly revenue stream associated with hosted software contracts."
