PLEASANTON, Calif.--(BUSINESS WIRE)--June 10, 2003

Commerce One (Nasdaq:CMRC) today announced momentum in the Asia Pacific region through new customer acquisitions in the first half of this year, including customers for its new composite applications platform, Commerce One Conductor(TM). Far EasTone and Korean Aerospace Industries have chosen Commerce One Supplier Relationship Management (SRM) solutions to attain heightened efficiency and collaboration in their sourcing and purchasing processes. Industrial Technology Research Institute (ITRI) joins GTWebKorea in selecting the Commerce One Conductor platform.

"ITRI turned to Commerce One for its history and expertise in helping companies collaborate over the Internet," said Dr. Peter Wang, deputy general director of ITRI. "We specifically chose Commerce One Conductor for its ability to automate and manage complex processes and interactions between users."

ITRI selected the Commerce One Conductor platform to support its joint venture with the Taiwanese government in creating the Silicon Intellectual Property Mall to provide an Internet-based catalogue for chip developers to share and contribute intellectual property across their community. The Commerce One Conductor platform is designed to transform and accelerate the way applications and business processes are deployed by helping companies to quickly and easily create, connect and coordinate business processes between customers and partners without being limited by the constraints of existing applications or platforms.

Commerce One also continued to build upon its strong position in the SRM market with new customer wins including Far EasTone, a leading telecommunications provider in Taiwan, which was secured through Commerce One's partnership with Com2B of Taiwan, and the Korean Aerospace Industries (KAI), the Republic of Korea's national aerospace company established with the consolidation of Samsung Aerospace, Daewoo Heavy Industries and Hyundai Space and Aircraft Co.

"The customer activity we are experiencing in the Asia Pacific area is indicative of our strong reputation in the region. Our technology is specifically designed for the type of global reach and tight partnerships that are the hallmark of Asian companies," said Mark Hoffman, chairman and CEO, Commerce One. "Given the positive feedback we are receiving, we are clearly addressing an important need by offering new technologies that make systems connect more deeply, reach more broadly and adapt more easily."
