ATG Announces Changes to Operations Management Team.

Business/Technology Editors

ATG (Art Technology Group, Inc., Nasdaq: ARTG), a leading developer of online CRM applications for commerce, portals, and relationship management, today announced that Chief Operating Officer Bernard Bailey will be resigning from the company, effective August 3, and transitioning his management responsibility over the coming weeks. Bailey is leaving ATG to take the role of chief executive officer at a publicly traded biometric technology company. Bailey's responsibilities will be assumed by Greg Lazar, who has been promoted from vice president of North American sales to vice president and general manager for North America, and ATG's current Vice President and General Manager of International Operations, Bernard Girbal. The company also announced today the appointment of John Dragoon as senior vice president of product management and marketing (see separate release issued today).

"Since joining the company in January 2001, Bernard has been a key contributor in helping to build a solid organizational and operational infrastructure and we wish him all the best in his future endeavors," said Paul Shorthose, president, CEO chairman of ATG. "During their tenure with ATG, Greg Lazar and Bernard Girbal have been instrumental in continuing our momentum during a tough economic climate. We continue to strengthen our foothold within the online CRM market and we are fortunate to have such seasoned executives step up in their new roles."

In his time at ATG and working side by side with Bailey, Lazar has been responsible for the company's continued success in winning brand-name customers such as Best Buy, AT&T, Ford Motor Credit, and Restoration Hardware. Under Lazar's direction, ATG also secured and expanded key alliances with companies like BEA, IBM, and Accenture as well as Fort Point, McFadyen and Blast Radius. As vice president and general manager of North America, Lazar will report directly to Shorthose with the responsibility of overseeing sales, channel, services and operations.

Continuing in his present position and now reporting directly to Shorthose, Girbal has had a positive impact in reorganizing and restructuring ATG's EMEA and Asia Pacific regions to reduce operational expenses. He has also been responsible for securing major customers including France Telecom, Renault, TV Asahi, and Sasol as well as key alliances with HP Japan and Vodafone. In addition, he has played an important role in expanding ATG's relationship with Accenture.

Rounding out the executive management team is Bill Stephens (see related announcement, dated May 23, 2002). As vice president and general manager for government solutions, Stephens is responsible for ATG's growing traction in e-government initiatives. He is focused on strengthening relationships with government integrators including EDS, RTGX, and GTSI, as well as growing ATG's government customer base, which currently includes the U.S. Army and USDA.
