Dassault Systèmes to Acquire Engineous Software
 
Expands PLM 2.0 for Simulation Lifecycle Management
 
 
Paris, France, and Providence, R.I., USA, June 17, 2008 – Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions and Engineous Software, a market leader in process automation, integration and optimization, today announced an agreement in which DS would  acquire Engineous Software. This acquisition will extend SIMULIA’s leadership in providing Simulation Lifecycle Management solutions on the V6 IP collaboration platform. The proposed acquisition, for an estimated price of 40 million USD, should be completed before the end of July subject to specific closing conditions. The transaction is expected to be non dilutive on DS non-GAAP 2008 earnings. 
 
“The combination of SIMULIA’s domain expertise in Realistic Simulation, the new Dassault Systèmes V6 PLM 2.0 platform, and industry-proven Engineous technology will provide customers with an unmatched capability for collaborative management of simulation applications, processes, data and intellectual property,” stated Scott Berkey, CEO, SIMULIA. “Our new SLM solution is already establishing market leadership momentum and the integration of Engineous’ FIPER framework as well as its design performance exploration tools will enrich and quicken our clients’ capabilities to deliver better products.”

Engineous’ FIPER software has evolved to become the leading distributed product development infrastructure that allows organizations to access, execute, and reuse design simulation tools and processes. The software allows resources to be connected within an organization and externally with partners and geographically dispersed design teams. Engineous customers include: Boeing, GM, Nissan, Procter & Gamble, Caterpillar, Canon, Rolls Royce, United Technologies, General Electric, Samsung and Toyota.

 “We are extremely pleased to be joining Dassault Systèmes and the SIMULIA brand team,” stated Siu Tong, founder of Engineous Software. “Our vision, from the start, has been to help define and build solutions for the management and automation of simulation activities within the enterprise. Becoming part of Dassault Systemes will allow our team to play an integral role in the democratization of realistic simulation for companies, their ecosystem and their customers, establishing SIMULIA SLM as the standard for enterprise simulation frameworks.”
 
 
Originally sponsored by an industry alliance, including Engineous Software, Goodrich, General Electric, OAI, Parker Hannifin and Ohio University, the Federated Intelligent Product EnviRonment project enabled Engineous to commercialize their FIPER product, which streamlines the design of engineered products, integrating legacy and best-of-breed analytical and design tools through a Web-enabled environment.

"We have enjoyed considerable success in deploying solutions from both Dassault Systèmes and Engineous as part of our overall digital engineering capability," said Dr. Byungsik Kang, Director of CAE, Vehicle Technology Center of Hyundai-Kia Motors Corporate Research & Development Division. "The integration of Engineous and SIMULIA solutions within the open Dassault Systemes environment represents an exciting opportunity for CAD/CAE system improvements which we look forward to with great interest as our enterprise digital engineering strategy evolves. We are very pleased with this unification from our most dependable partners."
