Mumbai, India, March 15, 2007 - Dassault Systèmes (DS) (Nasdaq: DASTY; Euronext Paris: #13065, DSY.PA), a world leader in 3D and Product Lifecycle Management (PLM) solutions, today announced it has secured a major order from Larsen & Toubro Limited. The technology-driven engineering and construction giant will adopt cutting edge integrated PLM solutions from DS for its heavy engineering division. DS’s solutions will integrate Larsen & Toubro’s stand-alone design automation and project management tools, increasing efficiency and savings potential across the division.

“L&T believes that product and process innovation are at the core of the company’s ability to compete in the global marketplace. The DS solutions will help give an enhanced focus on value creation and process simplification,” explains Mr. M. V. Kotwal, Director and Senior Executive Vice President Heavy Engineering, Larsen & Toubro. “Working closely with DS fits well with our enhanced thrust in the manufacturing sector. DS’s PLM solutions allow users to create a collaborative workplace that breaks down the barriers between engineering and design functions, accelerating the product development process and bringing about a new level of decision support, innovation and collaboration,” continues Mr. V. K. Magapu, Chief Executive, L&T Infotech and Member of the L&T Board. DS’s end-to-end PLM solution will be implemented by L&T’s IT arm - L&T Infotech.

“Larsen & Toubro operates at the upper end of the technology spectrum and has been at the forefront of introducing new processes, products and materials into the manufacturing sector for over six decades. The company has embraced a long term PLM strategy as critical to maintaining a competitive advantage. As part of its business transformation drive, L&T has extended this to include the collaborative intelligence capabilities of our ENOVIA solutions throughout the product delivery process with customers, partners and suppliers,” says Bruno Latchague, EVP, Dassault Systèmes. L&T will apply DS’s solutions to processes for the shipbuilding business segment. The deployment includes:


CATIA, for designing the virtual product,


ENOVIA VPLM, 3D collaborative virtual lifecycle management for highly complex products, resource and manufacturing processes,


and ENOVIA MatrixOne, collaborative product development business processes for enterprises.

This customer win is the first end-to-end implementation of a recently established partnership between Infotech Limited and DS.
