i2 COMPLETES ACQUISITION OF RIGHTWORKS

Combined Strengths Provide Expanded Solutions for Supplier Relationship
Management and E-Procurement

         DALLAS, TEXAS - AUGUST 22, 2001 - i2 Technologies, Inc. (Nasdaq: ITWO),
today announced that its acquisition of RightWorks Corporation, formerly an
Internet Capital Group (Nasdaq: ICGE) partner company, has been completed. With
RightWorks, i2 offers a collaborative e-procurement solution that allows
e-businesses and marketplaces to manage spend aggregation across procurement
partners in the extended supply chain.

         Under the terms of the agreement, a total of 5.35 million shares of
common stock is issuable in exchange for all of the outstanding capital stock of
RightWorks and indebtedness owed by RightWorks to Internet Capital Group. Based
on i2's closing stock price of $6.45 on Tuesday, August 21, 2001, the
transaction value is approximately $34.5 million. 561,024 of the shares will
remain in escrow for one year. In addition, i2 also had certain funding
obligations to RightWorks that terminated at the closing of the transaction. The
transaction will be accounted for as a purchase and is expected to be a tax-free
reorganization.

         RightWorks' e-procurement technology and transaction capabilities are
being added to i2's Supplier Relationship Management (SRM) suite, creating a
comprehensive solution that provides strategic sourcing, collaborative design
and manufacturing, and collaborative e-procurement for both direct and
mission-critical MRO goods. RightWorks' technology also strengthens the commerce
and transaction management capabilities of i2's platform. The i2 solution is
intended to provide a collaborative e-procurement solution that can enable
multi-enterprise, real-time pricing and availability, order brokering, and
multi-language and currency transactions.

         "In today's economy, customers are looking for tangible benefits and
solutions that enable them to make more cost-effective procurement decisions
across the entire supply chain," said Romesh Wadhwani, i2 vice chairman. "By
incorporating RightWorks' technology, i2 will create an e-business platform for
marketplaces and enterprises that offers collaboration, content and commerce,
and returns hard dollar benefits to customers."

         RightWorks' solutions and network are being incorporated into i2's
TradeMatrix Open Commerce Network, SRM solutions and content applications. The
combined technologies will allow i2 customers to leverage a comprehensive
procurement process for both direct and indirect materials through a single
platform, significantly expand the supplier enablement services provided, and
extend i2's lead in content management and reference data solutions.

i2'S COMMITMENT TO OPEN INTEGRATION

         E-business transformation begins with a holistic view of an enterprise
and its trading partners, and applies technology to speed business processes and
collaboration. This requires the ability to integrate to existing legacy
information systems. The RightWorks acquisition continues i2's long-standing
commitment to open integration with other systems, as the RightWorks technology
is also based on an open, integratable technology base. As a customer-focused
company, i2 intends to continue to integrate its solutions and support customers
who may use other e-business or e-procurement solutions.
