ITEM 12 -- SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

   The following table sets forth specified information with respect to the beneficial ownership of our common stock as of February 28, 2001 by: (1) each person (or group of affiliate persons) who is known by us to beneficially own 5% or more of our outstanding common stock; (2) each of the Named Executive Officers; (3) each of our directors; and (4) all directors and executive officers as a group.

   The beneficial ownership is calculated based on 36,771,893 shares of our common stock outstanding as of February 28, 2001. Beneficial ownership is determined in accordance with SEC rules. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of common stock subject to options held by that person that are currently exercisable within 60 days of February 28, 2001 are deemed outstanding. Such shares, however, are not deemed outstanding for the purpose of computing the percentage of each other person. To our knowledge, except pursuant to applicable community property laws, the persons named in the table have sole voting and investment power with respect to the shares set forth opposite such person's name. Unless otherwise indicated, the business address of such stockholder is c/o The TriZetto Group, Inc., 567 San Nicolas Drive, Suite 360, Newport Beach, California 92660.
