iCollaboration to Add Critical Business-to-Business Collaboration

Functionality to MarketSite's Direct Material Capability,

Improving Speed, Responsiveness and Service Levels

Adexa, Inc., the leading provider of business-to-business (B2B) collaborative solutions critical to e-business (formerly Paragon Management Systems), and Commerce One (Nasdaq: CMRC), the leading provider of global e-commerce solutions, have entered into a strategic relationship to integrate Adexa's collaborative planning solution, iCollaboration, with Commerce One MarketSite(tm) Portal Solution addressing the B2B direct material market.

It is believed that iCollaboration will enable MarketSite to better link buyers and suppliers as well as synchronize order procurement and fulfillment activities through the use of dynamic business-to-business collaboration tools. iCollaboration will provide MarketSite customers - Fortune 500 to 2000 buyers - with improved customer service levels through accurate order promising, intelligent allocation and collaboration capabilities. The solution will also provide MarketSite's suppliers with value-added services such as demand visibility and order allocation capabilities, allowing them to more rapidly respond to changing demand.

"iCollaboration provides trading exchanges, such as Commerce One's MarketSite, with the critical element required for the next wave of e-Business - business-to-business collaboration between customers and trading partners," said Dr. K. Cyrus Hadavi, president and chief executive officer of Adexa, Inc. "By integrating iCollaboration with MarketSite, we'll help improve the level of customer service MarketSite can provide to its corporate buyers while increasing the speed and responsiveness of its suppliers."

iCollaboration delivers a competitive advantage by helping companies as well as trading exchanges collaborate more effectively with their extended supply chain - improving the level of value-added services they provide to their buyers and suppliers. iCollaboration improves operations of the extended supply chain through business-to-business collaboration and process automation.

"We believe that Adexa's iCollaboration capabilities are synergistic with MarketSite architecture and needs," said Mark Hoffman, CEO of Commerce One. "iCollaboration will enhance our ability to deliver customer service to MarketSite buyers while improving the speed and responsiveness of suppliers by helping to communicate and collaborate more effectively."
