COMMERCE ONE AND RIOLABS TEAM TO CONNECT
SUPPLIERS TO COMMERCE ONE.NET

Alliance Focused on Driving Business Commerce onto the Web

Denver, CO., November 1, 2000 - RioLabs Inc., a leading provider of supplier
exchange integration technology for business-to-business (B2B) electronic
commerce solutions, and Commerce One, Inc. (NASDAQ: CMRC), the leader in
global e-commerce solutions for business, plan to work together to make it
easy for suppliers to connect and conduct business on Commerce One.net -
leveraging both XML and EDI technology platforms.  RioLabs and Commerce One
have signed a preliminary non-binding memorandum of understanding.
Definitive agreements are expected to be executed by first quarter of 2001.

RioLabs intends to offer its cross-platform solution to suppliers connecting
with Commerce One.net, an open e-marketplace that provides global e-commerce
services to buyers, suppliers and Net Market Makers.  RioLabs’ flagship
product, RioTrade, allows companies to execute direct mission-critical
business processes, such as loading catalogs, real-time price and inventory
checks, purchase orders and order confirmations, through Commerce One.net.
This enables seamless, real-time business transactions among diverse trading
partners.

"As a leading e-marketplace, Commerce One.net offers buyers, suppliers and
e-marketplace operators a powerful way to buy and sell globally," said Bob
Hale, CEO of RioLabs, Inc. "RioLabs provides a product empowering
e-marketplaces and suppliers with immediate transaction capability.  The
ability to bring these suppliers online in days is the type of critical
traction e-marketplaces must demonstrate to succeed. “

"We believe the strength and flexibility of RioLabs’ flagship product
RioTrade, will help Commerce One.net achieve maximum return on investment in
the shortest possible time," said Roy Satterthwaite, vice president of
Commerce One.net.  "We believe RioLabs will addresses one of the most
important areas of B2B e-commerce, helping suppliers get online and
transacting."

RioLabs provides a full range of B2B solutions that let companies realize
their e-commerce strategies.  Through broad support of open standards and
protocols, such as Commerce One’s xCBL, RosettaNet, Microsoft BizTalk, OBI,
OAG, FpML, ACORD, ANSI X12 and EDIFACT EDI, RioTrade links to multiple
e-marketplaces using any of the various standards.

suppliers in the e-commerce market place.  RioLabs’ technology makes the
promise of  B2B e-commerce a reality by rapidly and automatically linking
enterprise information sources with exchanges or direct trading solutions.
RioLabs provides an easy-to-use, two-way, e-commerce transaction capability,
greatly reducing the time-to-market for  e-marketplaces, direct suppliers,
Web-based catalogs and ASPs.  These results are achieved in days rather than
several months for integration.  As a result, enterprise organizations are
able to realize a strong strategic competitive advantage and an extremely
rapid return on investment.
