Business/Technology Editors

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sept. 25, 2002

ATG(R) (Art Technology Group, Inc., Nasdaq: ARTG), a leading developer of online CRM applications for commerce, portals and relationship management, today announced that DZ BANK, the cooperative central bank of the German Volksbanken and Raiffeisenbanken, has successfully deployed its corporate portal using ATG Portal. The new portal, which features intranet and extranet capabilities, has enabled DZ BANK to consolidate multiple initiatives onto a single transactional portal.

DZ BANK was formed in September 2001 following the merger of GZ-Bank and DG Bank. Following the merger, DZ BANK executives soon recognized that consolidating existing initiatives onto a single platform would allow the company to strengthen its employee relationships. Implemented by Entory AG in just six months, DZ-infoNET is accessible to the employees of DZ BANK as well as the more than 100,000 employees of the 1,400 Volksbanken and Raiffeisenbanken cooperative banks it serves.

"What convinced us most was the functionality of the ATG solutions and their scalability, as well as the capability to develop our portal quickly and flexibly," says Edwin Schaaf, project manager, DZ BANK. "Another key decision criteria was the compatibility of the ATG Portal with leading J2EE application servers. This allows us to maintain our in-house standard while deploying the applications based on the IBM WebSphere application server."

DZ-infoNET provides users with an extensive resource of information relating to all forms of banking and financing. By leveraging ATG's Scenario Personalization, DZ BANK is able to provide its employees with a robust user experience. Access to information and transaction privileges are granted to individual users based on their role within the organization. In the future, DZ BANK plans to further capitalize on the personalization functionality of ATG Portal to enhance its corporate extranet to create and deliver targeted campaigns to users, based upon their individual preferences.

"The flexibility and scalability of ATG Portal has enabled DZ BANK to consolidate a number of disparate Web-based initiatives into a single, cohesive online presence," said Matt Price, vice president, ATG Portal. "By doing so, DZ BANK has deployed a platform from which it can maintain and strengthen the relationships it enjoys with its entire employee base."
