    Business Editors/Technology Writers

    CAMBRIDGE, Mass.--(BUSINESS WIRE)--Feb. 28, 2005--ATG (Art Technology Group, Inc., NASDAQ: ARTG), the software provider behind the most consistent and relevant marketing, commerce, and service experiences, today announced the results of independent reviews of the company's corporate governance practices. In December 2004, ATG's board of directors engaged three highly respected independent corporate governance experts, the Corporate Governance Center at Kennesaw State University, the corporate governance advisory firm Board Assets, Inc. and the law firm of Wachtell, Lipton, Rosen & Katz to evaluate ATG's corporate governance structure, policies and procedures.
    In the executive summary of their joint report, the Corporate Governance Center at Kennesaw State University and Board Assets, Inc. wrote, "In our opinion ATG has excellent corporate governance policies, procedures and practices. We believe that the ATG directors are committed to considering the long-term success of ATG and do what they believe is in the best interests of the corporation and its shareholders. In addition, ATG has governance processes and procedures in place designed to help ensure that the right mix of directors is involved in decision making. They make decisions with quality information and work in an environment and culture that is highly functional and effective. In summary, in our opinion, ATG has an efficient and well functioning board."
    In its separate report, Wachtell, Lipton, Rosen & Katz noted, "We believe that the Company has generally adopted state-of-the-art corporate governance programs, and that the Company's takeover defenses are consistent with sound governance and a commitment to stockholders."
    Paul Shorthose, Chairman of ATG's board of directors, stated, "These independent reports reaffirm our belief that ATG's board is adhering to corporate governance best practices. The board remains committed to continuing to strengthen its governance practices, providing quality oversight to ATG, and ensuring that the company continues to build value for its shareholders."
    Based in part on recommendations in these reports, ATG's board of directors has undertaken the following initiatives, among others, to further enhance the company's corporate governance practices. The ATG board will refine the process for establishing and measuring long-term strategic goals, formalize a management succession plan, consider a policy requiring ownership of the company's shares by directors, and review and clarify the process by which the company's stockholders can contact the board.
    The board amended the company's stock option plans to remove provisions that would permit loans to any officers or directors. The board also reviewed the company's anti-takeover measures and determined, consistent with the reports of the independent consultants, that these provisions are reasonable and strengthen the board's ability to make decisions in the best interest of all stockholders. The board intends to review these provisions annually to determine whether they continue to support the board's efforts to carry out its responsibilities to the company's stockholders.
    ATG is actively searching for an additional independent director to join its board of directors and has engaged a search firm to assist it in that process. The new director, who will be appointed as a Class I director, will be selected by the board with input from several of its larger stockholders.
