DaimlerChrysler Signs Multi-Million Euro Contract for
DELMIA Digital Manufacturing Technology

Agreement is critical to automaker’s objective to cut costs
and continue to deliver top-of-the-line, quality products to consumers

Auburn Hills Mich., USA — February 9, 2005 — Delmia Corp., a Dassault Systèmes company (Nasdaq: DASTY: Euronext Paris: #13065, DSY.PA), today announced a multi-million Euro sale of the DELMIA Digital Factory (DF) solution to DaimlerChrysler Corp. DaimlerChrysler will use DELMIA in Mercedes Car Group’s DF project. This agreement reinforces the strategic partnership between DaimlerChrysler and Delmia Corp.

The DF project is one of the largest IT projects within DaimlerChrysler. The DELMIA DF solution includes planning and optimization processes for digital product and process validation, assembly, body manufacturing, and chassis and assembly production as well as logistics for DaimlerChrysler vehicle projects.

The solution supports system-supplier cooperation and enables the company to distribute work among several locations, while improving quality, reducing costs and shortening production time. Particularly for the early stages of planning, implementation of DELMIA DF represents a major step toward Mercedes Car Group’s goal of delivering quality products while effectively managing increasing competition and cost pressure.

“The cooperation with our partner, Delmia Corp., started well before the agreement was signed and has laid the foundation for the success of this strategic project,” said Günter Walz, head of production planning at Mercedes Car Group.

“With this agreement, which confirms the confidence and great expectations of both partners concerning long-term cooperation, the partnership between DaimlerChrysler and Delmia Corp. has reached a decisive stage,” said Philippe Charlès, CEO, Delmia Corp. “This development is based on the successful performance of the project, which indicates that companies can realize great savings through digital validation of manufacturing processes. Following considerable investment by DaimlerChrysler in DELMIA solutions in recent years, the general agreement governs the modalities for the use of DELMIA software in the imminent broad-based rollout.”
