CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sept. 18, 2000

Art Technology Group, Inc. (ATG) (NASDAQ:ARTG) today announced the creation of the ATG Customer Advisory Council, an executive-level forum for ATG and customers to share discussions on best practices in online customer management, product direction and e-business applications. The first council includes representatives from AT&T, Egreetings Network, General Motors, John Hancock Funds, LetsBuyIt, and Procter & Gamble.

In response to customer requests for a business forum, ATG initiated the development of a customer-focused advisory program. The Council was created as an open exchange of ideas and best practices from key business leaders representing a cross-section of geographies, vertical industries, dot-coms, and traditional brick and mortar companies in the ATG community. ATG believes that maintaining close relationships with business visionaries in its customer base is essential to strategic planning and the product development process. The Council serves as a forum for ATG and its customers to exchange ideas on industry trends and practices and on the future direction and requirements for ATG's corporate and product strategy.

"Our customers represent an extraordinary range of innovative business models. Many are true visionaries that have helped ATG pioneer the customer relationship management and e-commerce marketplace," said Paul Shorthose, ATG President and COO. "The ATG Customer Advisory Council was established as a forum to understand our customers' e-business strategies and address them with next-generation technology and services."

ATG's Customer Advisory Council Charter Members include:

-- Bob Gingras (Chairperson), Director, eCommerce, General Motors

-- Behrouz Arbab, CTO, Egreetings Network

-- Doug Bethea, Associate Director - eBusiness, Procter & Gamble

-- Gerry Sullivan, Director, eCommerce, John Hancock Funds

-- Jan-Erik Gustavsson, CTO, LetsBuyIt

-- Rene McGee, General Manager, Information Management & Technology, AT&T

-- Steve Solomon, AT&T Web Site Services, AT&T

The ATG Customer Advisory Council is expected to meet three times a year and consists of seven members serving one and a half-year terms with staggered end dates. ATG selects Council members who are business leaders in their respective industries and can address the use of technology in a business context. The Council promotes professional networking and informational exchange, as well as constructive face-to-face time with ATG executives. Leveraging the success of its first meeting held last month, the global Council members will also participate in the meetings of ATG's upcoming regional Customer Advisory Councils.
