                       AMENDMENT NO. 1 TO RIGHTS AGREEMENT

            AMENDMENT NO. 1 (this "AMENDMENT"), dated as of April 28, 2002, to

between Trigon Healthcare, Inc., a Virginia corporation (the "COMPANY"), and
National City Bank, as successor to First Chicago Trust Company of New York, as
Rights Agent (the "RIGHTS AGENT").

            WHEREAS, the Company and the Rights Agent have heretofore
executed and entered into the Rights Agreement;

            WHEREAS, pursuant to Section 27 of the Rights Agreement, the Company
may from time to time supplement or amend the Rights Agreement in accordance
with the provisions of Section 27 thereof;

            WHEREAS, the Company also proposes to enter into a Stock Option

limitation, the Merger (as defined in the Merger Agreement), are fair to and in

affected, impaired or invalidated. Upon any such determination that any term or
other provision is invalid, illegal or incapable of being enforced, the parties
hereto shall negotiate in good faith to modify such provision so as to effect
the original intent of the parties as closely as possible and in an acceptable
manner with respect to such provision to the greatest extent possible.
