Update newsletter debuts today

        Welcome to the first edition of The Transition Update. This electronic newsletter is designed to give Trigon employees and Anthem associates reliable and accurate information on transition news.

        As you know, there is a superb strategic fit between the two companies, and equally important, a superb cultural fit. Both Trigon and Anthem put the customer first and focus on excellence in service and operations. There are many areas for collaboration and sharing of best practices. This newsletter will serve as a tool for Trigon employees and Anthem associates get to know each other and both companies. Building strong working relationships now will lead to a smooth transition in the months ahead.

        Regular features of the Update will include reports from various transition teams; news from Trigon and Anthem; interesting facts and trivia; profiles of key transition or management leaders; answers to your questions; and more. Our goal is to provide you with reliable and accurate transition news.

Questions & Answers

        An important function of The Transition Update is to answer questions submitted from people at Trigon and Anthem. We anticipate getting a wide variety of questions, some that apply to Trigon only, some that are geared toward Anthem and others that apply to both. Therefore, Questions & Answers is the only section of the Update that will vary depending on the audience.

How will the transition process work?

        Trigon and Anthem are in the process of forming "transition teams" that will work through the best practices of both companies and help them combine in the most effective way possible. The transition teams will be guided by the Executive Steering Committee, led by Trigon's Chairman and Chief Executive Officer Tom Snead and Mike Smith, Anthem chief financial officer. Trigon's John Brighton, chief information officer; Tom Byrd, chief financial officer; Anthem's Dave Frick, chief legal and administrative officer; and Jane Niederberger, chief information officer will also serve on the Executive Steering Committee. Others from functional areas of both companies will be involved in the process. We will provide you with more details in the next few weeks as the transition teams come together.

        SAFE HARBOR STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

        This newsletter contains certain forward-looking information about Anthem, Inc. ("Anthem") and the combined company after completion of the transactions that are intended to be covered by the safe harbor for "forward-looking statements" provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that are not historical facts. Words such as "expect(s)", "feel(s)", "believe(s)", "will", "may", "anticipate(s)" and similar expressions are intended to identify forward-looking statements. These statements include, but are not limited to, financial projections and estimates and their underlying assumptions; statements regarding plans, objectives and expectations with respect to future operations, products and services; and statements regarding future performance. Such statements are subject to certain risks and uncertainties, many of which are difficult to predict and generally beyond the control of Anthem, that could cause actual results to differ materially from those expressed in, or implied or projected by, the forward-looking information and statements. These risks and uncertainties include: those discussed and identified in public filings with the Securities and Exchange Commission ("SEC") made by Anthem; trends in health care costs and utilization rates; our ability to secure sufficient premium rate increases; competitor pricing below market trends of increasing costs; increased government regulation of health benefits and managed care; significant acquisitions or divestitures by major competitors; introduction and utilization of new prescription drugs and technology; a downgrade in our financial strength ratings; litigation targeted at health benefits companies; our ability to contract with providers consistent with past practice; our ability to consummate Anthem's acquisition of Trigon Healthcare, Inc. ("Trigon"), to achieve expected synergies and operating efficiencies in the Trigon acquisition and to successfully integrate our



operations; our expectations regarding the timing, completion and accounting and tax treatments of the transactions and the value of the transaction consideration; and general economic downturns. You are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof. Anthem does not undertake any obligation to republish revised forward-looking statements to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. You are also urged to carefully review and consider the various disclosures in Anthem's various SEC filings, including but not limited to the registration statement on Form S-4, including the preliminary joint proxy statement/prospectus constituting a part thereof, filed by Anthem on May 21, 2002, Anthem's Annual Report on Form 10-K for the year ended December 31, 2001, and Anthem's Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2002.
