Dassault Systemes S.A. (the "Company") is furnishing under cover of Form 6-K a
press release dated March 9, 2004, announcing the release, with IBM, of Version
5 Release 13 (V5R13) of their product lifecycle management (PLM) portfolio.

                  Dassault Systemes and IBM Announce Version 5
                     Release 13 of their Product Lifecycle
                              Management Portfolio

            "PLM Workspace for Collective Innovation" revolutionizes
                   product development by merging design and
                     data management in single V5 interface

Paris, France - March 9, 2004 - Dassault Systemes (Nasdaq: DASTY; Euronext
Paris: #13065, DSY.PA) and IBM today announced the release of Version 5 Release
13 (V5R13) of their product lifecycle management (PLM) portfolio, comprised of
CATIA for collaborative product development, and ENOVIA and SMARTEAM for product
data and life cycle management, collaboration, and decision support.
Concurrently, Dassault Systemes announced V5R13 of DELMIA for the engineering of
lean manufacturing processes.

V5R13 is the result of development collaboration between industry-leading
manufacturers, their supply chains, and Dassault Systemes. These companies have
chosen V5R13 to support their major new product programs.

The new release extends the power of leading-edge engineering practices to
include relational design, a breakthrough PLM best practice that provides
engineers with full visibility on dependencies and the impact of their
decisions. With relational design, they can better manage design modifications,
including impacts on functional specifications, analysis, and manufacturing
constraints. This practice results in higher quality designs the first time,
fewer engineering changes later in the design cycle, and more opportunity for

A major innovation in the V5R13 release is the new ENOVIA VPM Navigator product
that enables manufacturers to take maximum advantage of relational design,
integrating ENOVIA's virtual product definition into CATIA's easy-to-use design
environment. This unified PLM workspace empowers teams to work together as one
during the critical product development phases, resulting in faster and easier
"right first time" collective product innovation.

V5R13 also extends industry-specific capabilities that support new product
introduction programs, makes them available to supply chains and smaller
businesses, and improves deployability through increased openness and standards

The V5R13 product portfolio brings business value to manufacturers in the
following areas:

Powers Major Product Programs - V5R13 powers major product programs by enabling
manufacturers and their supply chain to deploy competitive new PLM best
practices that reduce development cycles by at least 20%.

Design in Context, Decide in Context - ENOVIA VPM Navigator provides
unprecedented data management capabilities from within the familiar environment
of CATIA, allowing engineers to manage their designs in the context of the
overall product, collaborate in a dynamic design environment, avoid errors, and
speed development cycles. The new application enables companies to view the full
implications of design changes in order to facilitate decision-making and reduce
the risk associated with new product innovation.

Process Expertise Inside - Best practices captured in new industry-specific
applications and process templates enable manufacturers to deploy competitive
methodologies to increase productivity through streamlined processes. For
example, V5R13 introduces new specialized CATIA products for automotive
body-in-white, electrical design and documentation, and cast and forged parts.

World Class PLM for Medium-sized Businesses - V5R13 makes robust PLM practices
available to companies of all sizes through specialized right-sized PLM packages
for Industrial & Consumer Products, the Electronics industry, and the Automotive
and Aerospace Supply Chains. SMARTEAM's new platform-independent infrastructure,
thin-client CATIA integration and Program Management extend product life cycle
capabilities within and beyond the corporate firewall.

Proven Openness and Standards Support - Underscoring IBM and Dassault Systemes'
commitment to openness and global IT standards, V5R13 includes enhancements in
APIs, plug-ins, interfaces, and standards. These improvements make it easier for
companies to personalize their PLM platforms, share data with systems used by
partners, and integrate PLM solutions with legacy systems.

"V5R13 ushers in a new era of PLM-driven innovation," said Bernard Charles,
president and CEO, Dassault Systemes. "Merging product design with product data
management in a single unified environment makes it significantly easier for
engineers to effectively collaborate, navigate and work in context on complex
product structures. It enables them to exploit relational design to its full
extent. The benefit of knowing in advance the impact of engineering changes, as
well as the associated time savings, allows manufacturers to focus on innovation
- the key to success in today's competitive marketplace."

"To break into global healthcare markets, our company required a complete
solution for the development and delivery of innovative surgical instruments and
implants," said Sylvie Plumet, vice-president, Aesculap Implants, a European
leader in the medical implant device market. "Our new V5 platform delivers
improved product development and collaborative functionalities. Automated design
updates and tracking functions allow us to reduce the time necessary to develop
and deliver high quality orthopedic devices to a growing international market.
More importantly for our business, we now have total traceability of the entire
product development process. The PLM platform from IBM and Dassault Systemes
provides a complete solution for product design, collaboration and
documentation, all essential to stay competitive and grow our business."
