Paris, France, and Dallas, Texas, June 28, 2005 – Dassault Systèmes (NASDAQ: DASTY; Euronext Paris: #13065, DSY.PA), the world’s leading developer of Product Lifecycle Management (PLM) solutions, and i2 Technologies, Inc. (OTC: ITWH), a leading provider of demand-driven supply chain solutions, today announced that they have reached an important milestone in their strategic partnership for the development of sourcing solutions for PLM based on the Dassault Systèmes V5 platform.

The intent of the partnership, announced on May 10, is to enable cross-functional visibility and unmatched collaboration between the engineering and sourcing communities, bringing sourcing considerations to the engineer's desktop and engineering criteria and 3D digital mockup to the sourcing specialist.  

As an important step in the partnership, Dassault Systèmes has completed the planned acquisition of a center for the development of sourcing solutions for collaborative PLM from i2 for approximately $10 million. The ongoing partnership will continue to bring together Dassault Systèmes’ PLM expertise and V5 platform, along with sourcing expertise and SRM (Supplier Relationship Management) upgrades from i2. i2 will also continue to develop and sell its SRM solutions and support its customers.

Solutions produced through the partnership will be Dassault Systèmes-branded and will provide benefits such as the ability to design for supply, enhanced re-use management, optimized component and subsystem lifecycle management, and converging engineering and sourcing processes. For instance, engineers will be able to optimize design by taking into account part-sourcing information such as obsolescence, availability and companies' sourcing preferences early in the design cycle.
