Dassault Systèmes and PROSTEP AG Partner to Deliver Extensive Connectivity for ENOVIA SOA Enterprise Middleware for PLM

Commitment Strengthens Collaborative Intelligence Capabilities Across Federated PLM Data Regardless of Source

Paris, June 27, 2007—Dassault Systèmes (DS) (NASDAQ: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced an expanded CAA agreement with PROSTEP, a leading provider of solutions for product data integration.  PROSTEP will develop and sell a new  PLM SOA (service oriented architecture) connector taking advantage of DS’s ENOVIA SOA enterprise middleware architecture.  The connector will allow ENOVIA users to view, access, manage and collaborate across PLM content from heterogeneous data sources such as Teamcenter, Windchill, Agile and SAP PLM.

“PROSTEP is excited to work with Dassault Systèmes to create a powerful solution linking ENOVIA to a multitude of external sources. Together we are helping customers accelerate their collaborative development process by enabling all relevant PLM information to be centrally viewed, accessed and managed quickly, reducing cycle time and driving product innovation. Integration between PROSTEP’s OpenPDM and ENOVIA will immediately add value for customers by allowing them to easily integrate data from new sources into their ENOVIA environment,” says Bernd Paetzold, CEO of PROSTEP.

“This partnership proves DS’s commitment to an open platform and SOA architecture.  It demonstrates that the ENOVIA platform can be the federated repository and data warehouse for all customer, product, process, and resource data. The PROSTEP partnership is key for helping our customers to connect and reuse their legacy environment with DS’s innovative PLM solutions,” explains Stephane Declèe, senior vice president of R&D for ENOVIA. “Combined with the 3DLive user experience, it provides customers with an unprecedented level of intuitive access and collaborative intelligence across the breadth of federated data available, resulting in improved productivity and faster time to market for new products.”
