                    Canadian Aerospace Supplier Heroux-Devtek
                Integrates Product Lifecycle Management Solution
                         from IBM and Dassault Systemes

           Just 12 weeks into implementation, PLM platform has already
          improved business collaboration with aerospace manufacturers

Le Bourget, France and Longueuil, Canada - June 16, 2003 - IBM and Dassault
Systemes (Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today announced at the
45th Annual Paris Airshow that Heroux-Devtek, a leading Canadian aerospace
supplier specializing in landing gear, has selected their Product Lifecycle
Management (PLM) solutions to gain efficiencies and align itself with customer

IBM PLM Solutions, with CATIA(R) V5 for collaborative product development and
SMARTEAM(R) for collaborative lifecycle management developed by Dassault
Systemes, enables Heroux-Devtek to collaborate more efficiently with aircraft
manufacturing customers, such as Boeing and Lockheed Martin, who operate on
similar PLM platforms. The new PLM platform also addresses critical capabilities
required in the aerospace industry, such as smooth exchange of data and
regulatory compliance - including product traceability.

Taking full advantage of the PLM environment, the Heroux-Devtek engineering
department will optimize its performance to design, manufacture and build
custom-made landing gear and aircraft structural components. The solutions
provided by IBM and Dassault Systemes will provide a seamless flow of
information between Heroux-Devtek's design, production and support business
units and those of its customers to further improve productivity and product

"IBM PLM Solutions, with software from Dassault Systemes, are a natural fit for
our aerospace work," said Nagi Homsy, vice president Engineering, Heroux-Devtek.
"With the power of PLM, the engineering department can now manage its growth and
become a major player in its field."

"The CATIA-SMARTEAM solution enables Heroux-Devtek to involve downstream
stakeholders in product development from the earliest phases of each project,"
said Marcelo Lemos, president of Dassault Systemes of America. "In so doing, the
company can leverage its diverse product data and development teams to improve
product performance, compress project schedules, and cut costs."

Implementation services, including education and training for product-related
functions, are being carried out by IBM Business Consulting Services working
with Dassault Systemes Services as prime contractor and local business partners
Rand and Mecanica. The solutions, all running on Windows-based IBM
IntelliStation M Pro workstations, are already successfully managing a variety
of CAD design files and bills-of-materials.


The next stage of deployment will include linking SMARTEAM to Heroux-Devtek's
existing enterprise resource planning application, furnishing relevant
engineering information to manufacturing, finance, marketing and sales.
