PLEASANTON, Calif.--(BUSINESS WIRE)--Sept. 19, 2002

Actional, Baltimore, Cognos, Contivo, Sonic Software and VeriSign

Bring Additional Functionality to Commerce One 6.0

Commerce One, Inc. (Nasdaq:CMRCD) today announced that Actional, Baltimore, Cognos, Contivo, Sonic Software and VeriSign will all make key technology contributions to its new product suite, Commerce One 6.0. Using an open standards-based architecture, the new Commerce One Web services solutions will help customers connect and optimize applications and business processes throughout the enterprise. Initially focusing where customer demand is greatest, the solution will integrate all components of a supply network, enabling real-time, secure information exchange and reduced operating costs.

Despite the promise of ERP vendors and supply chain automation solutions, supply networks remain inefficient and unable to quickly adapt to fluctuating business needs. Commerce One is working directly with Actional, Baltimore, Cognos, Contivo, Sonic Software and VeriSign to enhance its solutions to solve the supply chain challenges facing most Global 2000 companies.

According to Andrew Mellors, capability development manager at BAE SYSTEMS, a top aerospace and defense contractor, "Building military hardware is amazingly complex, involving hundreds of contractors, subcontractors and thousands of parts. Our multifaceted supply chain is critical to the success of our company. When we wanted to streamline part of our supply chain we turned to Commerce One for help with moving our sourcing and procurement process onto Exostar, the e-marketplace for the aerospace and defense industry (powered by Commerce One). After a successful implementation, we shared our additional supply chain challenges with Commerce One. It is great to see that they are working with their partners to address our needs."

Actional brings its integration expertise to the Commerce One solution through Actional SOAPswitch, which exposes ERP and legacy system interfaces as reusable Web services. Actional helps the platform remove key barriers to adopting a standards-based integration architecture.

Baltimore Technologies adds e-security capabilities to the Web services platform, helping to ensure the highest levels of data security.

Cognos adds business intelligence technology, ensuring the highest quality of data collection, aggregation and analysis.

Contivo contributes its data modeling, data mapping and data transformation technology, helping the platform reduce data integration and implementation time and costs.

Sonic Software's SonicMQ(R) provides standards-based, enterprise-class messaging to Commerce One 6.0, ensuring the reliability and scalability of their Web services solutions.

VeriSign adds its Trust Services Integration Kit, which is a key component of the platform's security architecture.

"Commerce One is working with leading players to ensure that our new Web services solutions have the most secure and advanced integration and business intelligence capabilities," said Mark Hoffman, chairman and CEO of Commerce One. "Commerce One has always been focused on enabling complex inter-enterprise business processes. We continue to gain positive feedback from customers and prospects that our new product suite will solve a critical pain point for companies who need more control, more real-time visibility, and increased efficiencies throughout their supply networks."

Commerce One will make the Web services platform generally available in Q1 2003.
