NEWPORT BEACH, Calif. – January 11, 2007 – The TriZetto Group, Inc. (Nasdaq: TZIX) today announced that it has completed the acquisition of privately held QCSI (Quality Care Solutions, Inc.). As previously announced, the definitive agreement for the acquisition was executed on September 13, 2006. The company received regulatory clearance for the transaction on December 29th.

"Our acquisition of QCSI brings together two leading innovators of software and information technology solutions dedicated exclusively to the healthcare payer industry," said Jeff Margolis, TriZetto's chairman and chief executive officer. "We expect that the companies' larger combined footprint of payers and consumers will help enable and accelerate the next generation of consumer-retail healthcare innovations such as real-time point-of-service patient liability, pay for performance and personal health records."

Sherwood Chapman, QCSI's founder and chief technology officer added, "We are very excited to combine the power of QCSI's QNXTTM administrative engine and its architectural flexibility with the broad capabilities and financial strength of TriZetto. QCSI's and TriZetto's common industry focus and solutions approach will serve our customers well."

Under the agreement, TriZetto paid to QCSI equity holders approximately $130 million, net of cash received from QCSI in the transaction. In January 2008, contingent on certain factors, TriZetto may pay up to an additional $12 million including a $7 million earn-out and a $5 million hold back. The company also assumed approximately $1 million of QCSI's debt.

To help finance the transaction, TriZetto used $75 million of term debt from its recently expanded $250 million Wells Fargo Foothill credit facility. The company continues to have strong liquidity based upon its cash on hand, operating cash flow, revolving credit facility and unused portion of its term debt capacity.

As previously announced, the transaction is expected to be mildly dilutive to earnings per share in 2007. It is projected to turn accretive in 2008. The transaction has no effect on share count. The company anticipates providing 2007 guidance, including QCSI, no later than its fourth quarter 2006 earnings call that is scheduled for Monday, February 5, 2007.
