WALNUT CREEK, Calif.--(BUSINESS WIRE)--March 29, 1999--Commerce One, Inc. today announced an agreement with NTT for a joint project to establish a business-to-business electronic marketplace for the Japanese market. This marketplace will enable businesses to buy and sell goods and services through an open commerce portal that will deliver significant cost reductions and reduce cycle times over traditional trading methods.

As part of this alliance, NTT will license Commerce One's Commerce Chain Solution and work with Commerce One to offer an open commerce portal for the Japanese market that will automate trading between businesses. This deal combines Commerce One's strengths in developing and delivering electronic commerce solutions with NTT's strengths of nation-wide and international infrastructure, large customer base, and expertise in providing quality network services to deliver a comprehensive solution to Japan. The combined NTT and Commerce One solution will increase efficiency, streamline buying processes and reduce purchasing cycle times by automatically handling purchase authorization, accounting and contractual procedures resulting in significant cost reductions and a high return on investment.

NTT is building EC community services with partners through an open, interoperable commerce portal architecture. From NTT's perspective, Commerce One is a critical component of this strategy to deliver complete electronic commerce solutions to address the rapidly emerging electronic commerce marketplace in Japan.

"This agreement with NTT will enable Commerce One to extend its leadership in electronic commerce solutions from the US to Asia," said Mark Hoffman, president and CEO of Commerce One. "Our expertise in building marketplaces for electronic commerce, coupled with NTT's leadership in the Japanese market will enable us to jointly deliver a comprehensive solution and provide superior levels of customer support and service.
