Round Trip Integration Enhances Content Management Capabilities of

Commerce One MarketSite Portal Solutions

At the National Manufacturing Week conference today, Commerce One, Inc. (Nasdaq:CMRC), the leader in global e-commerce solutions for business, announced Round Trip, a service to rapidly link participants in online trading communities.

The company's Round Trip capability for accessing supplier content benefits both buyers and suppliers by enabling suppliers to offer branded, value-added services that leverage their own e-commerce infrastructure.

"Commerce One has earned a reputation as the leader in content solutions for business-to-business e-commerce," said Kirby Coryell, senior vice president of operations, Commerce One. "With Round Trip, we will add the e-commerce content functionality of the most sophisticated suppliers to the already leading-edge content management capabilities available today on the Commerce One MarketSite Portal Solution. We believe that the resulting end-to-end content management solution will benefit buyers and suppliers on a global basis."

Round Trip allows suppliers to maintain branded content on their own web sites and extend their e-commerce capabilities to buyers connected to MarketSite portals. Suppliers can "connect once" to a Commerce One MarketSite portal, gain access to a large marketplace of buyers and offer value-added services, such as configurators or specialized search engines, that simplify and enhance the buying experience. Buyers can interact with the supplier's web site using Commerce One BuySite or other buying applications connected to a Commerce One MarketSite, while maintaining their own business rules and processes. By simply connecting through the MarketSite portal to the supplier web site, they can select and configure products from the supplier's custom catalogs and bring the items back into the buying application for requisition approval.

"Integrating ImageX.com's (Nasdaq:IMGX) e-procurement solutions with Commerce One's Round Trip capabilities will make it easier for corporate purchasers in the Commerce One global trading community to modify, order and manage their printing needs online," said Rich Begert, president and chief executive officer of ImageX.com. "While our online printing services are available today on Commerce One's MarketSites, Round Trip will now enable print buyers to make their purchases with just a mouse click."

Round Trip is the newest addition to Commerce One's suite of content and transaction management services that enable the faster, more efficient trading relationships in every industry. Commerce One's breadth of e-commerce solutions can support trading partners with information technology infrastructures ranging from the most basic to the most sophisticated. Commerce One supports 100 percent of available content from a wide variety of sources, including transactive web sites, product search web sites, legacy-based content, and non-electronic content.

Round Trip is an ideal addition to Commerce One's proven managed content service that enables suppliers to "publish once" to a MarketSite portal, where their catalog content is categorized and normalized so buyers can easily search for and compare products.

Suppliers planning to offer site access via Round Trip represent many of the key commodities needed by today's Global 2000 buyers, such as office equipment and computers, MRO goods, electrical products, healthcare products, chemical goods, business services, branded promotional products and printing services. More than 30 vendors and suppliers have already endorsed Commerce One's Round Trip capability, including Boise Cascade, Cintas, Compaq, CompUSA, Corporate Express, Curtis 1000, DJS Marketing Group, eCompanyStore.com, En Pointe Technologies, Fatbrain.com, Fisher Scientific, Graybar Electric Company, ImageX.com, Interactiveprint.com, Lands' End, MadeToOrder.com, MicroAge, Moore Business Products, NECX, Newark Electronics, Noosh, Office Depot, RoweCom, RS Components, Sigma Aldrich, Software Spectrum, Staples Inc., Steelcase, TrainingNet, Wareforce.com, and Wesco Distribution.

Commerce One's XML technology and tools in Round Trip help suppliers, trading partners and Internet market makers accelerate trading through B2B e-commerce. The XML-based transaction platform enables heterogeneous systems to communicate and allows different portals to interoperate and connect to the Commerce One Global Trading Web(TM).

"As a leading online computer products vendor, Round Trip enables our customers to leverage many of our flagship eCommerce productivity tools, for example our memory configurator and our planned Gateway configurator,"said Jim Bruynell, Director B2B Division, NECX Direct. "Furthermore, as xCBL becomes the industry standard, our investment in this technology will enable our company to support unlimited buyer clients in their efforts to reduce procurement costs."

Availability

Round Trip will be available next month.
