                  IBM and Dassault Systemes Announce Version 5
                      Release 11 of their Product Lifecycle
                              Management Portfolio

           "Built-in Reality" - V5R11 PLM portfolio delivers unmatched
                   product realism and leading-edge solutions
                          for real-world industry needs

Paris, France - April 30, 2003 - IBM and Dassault Systemes (Nasdaq: DASTY;
Euronext Paris: #13065, DSY.PA) today announced the release of Version 5 Release
11 (V5R11) of their product lifecycle management (PLM) portfolio, comprised of
CATIA(R) for collaborative product development, and ENOVIA(TM) and SMARTEAM(R)
for lifecycle management, collaboration and decision support. Concurrently,
Dassault Systemes announced V5R11 of DELMIA(TM) for the engineering of lean
manufacturing processes.

Built-in Reality is the core concept of V5R11. It characterizes the exceptional
level of realism now attainable in product and process simulation. It also
reflects the high value that V5R11 delivers resulting from IBM and Dassault
Systemes' extensive experience working with industry-leading companies to create
realistic, effective PLM solutions.

V5R11 PLM solutions bring companies one step closer to e-business on demand by
enabling them to become more responsive, focused, resilient and variable in
ever-changing markets. The new features of the V5R11 PLM portfolio provide value
to customers in the following areas:

Predictive Lifecycle - Improved ability to anticipate product behavior and
manufacturing operations. V5R11 simulates products realistically so that
customers can anticipate in detail the behavior of future products and factory
manufacturing operations. This reduces the risk of product failure, production
inefficiency, market mismatches, and after-delivery compliance cost (products
that cost more to make than they can be sold for).

Engineering Emotion - Greater power to build the look and feel of a product.
V5R11 offers new innovative tools to better capture the aesthetic, visual design
that designers intend for a product. It also provides the user more
high-productivity tools to control and engineer product shape and deliver styled
products that can be manufactured easily.

Secure Circulation of Intellectual Property - A framework for safe sharing of
IP. V5R11 delivers enhanced security and authentication mechanisms for
collaboration and collective decision-making processes. Information representing
high-value IP, such as knowledge rules or CAE analysis data, is managed in a
controlled environment where intelligence is applied at every level. Access from
outside engineering is enhanced with ENOVIA's use of WebSphere Portal.

PLM Accessibility for All - Strengthened entry PLM across all industries. V5R11
becomes even more accessible to small and medium-sized businesses (SMB) and
gives them a significant competitive edge. Now SMBs in all industries, including
Fabrication and Assembly, Electronics, and Consumer Goods, benefit from complete
PLM solutions.


Turning Experience into Value - Leveraged PLM deployment know-how delivers core
processes productivity. V5R11 increases the benefits of IBM and Dassault
Systemes' extensive experience in deploying PLM solutions for industry-leading
companies. V5R11 contains specialized, high-value features for the major core
processes of all manufacturing industries, including Automotive, Aerospace and
Electronics industries.

"Ensuring customer product success is the ultimate goal of V5R11," said Bernard
Charles, president and CEO of Dassault Systemes. "With a focus on increased
reality - whether putting more realism in virtual product simulation, leveraging
our extensive experience, or responding to real industry needs - V5R11 helps our
customers produce successful products. The more they can anticipate a product's
behavior, the more they can avoid problems and reduce risks. In today's
competitive marketplace, getting it right the first time for a rapid return on
investment is critical."

"Innovation and cooperation are two cornerstones of our development strategy,"
said Anders Romare, Director PLM Solution Center, Volvo IT, a leading PLM
service provider to the automotive and discrete manufacturing industry. "The V5
PLM Platform helps us achieve these objectives by making it easier to
realistically simulate components and anticipate their operation. This combined
with improved reuse of corporate knowledge rules means that we can better
leverage our know how with suppliers and partners and boosts collaboration
across the extended enterprise. All of this translates into lower development
costs, shorter development cycles, and more interesting, innovative products."

V5R11 Brand Highlights: (for detailed V5R11 brand information, see

CATIA for collaborative product development - offers a range of new products and
enhanced features for mastering product success in the Automotive, Aerospace,
Fabrication & Assembly, Shipbuilding, Consumer Goods, and Electrical &
Electronics industries, as well as enhanced entry PLM products for small and
medium-sized companies.

ENOVIA for lifecycle management and decision support - transforms the customer's
product development organization into a source of competitive advantage with
increased support for complex product design, and a practical Web environment to
bring marketing, sales and customers earlier into the product development cycle
- where 80% of product costs are committed.

SMARTEAM for lifecycle and product data management - enhances and accelerates
the proliferation of product knowledge and business processes across the
enterprise and product value chain with tighter CAD integrations, expanded
collaborative design, improved web collaboration, new methodologies, and
improved data capture, mining, and reuse capabilities. SMARTEAM will also
feature IBM Websphere Express, a flexible, low cost solution for enterprise
integration for disparate application environments.

DELMIA for the engineering of lean manufacturing processes - includes enhanced
end-to-end coverage for the Automotive industry, better integration of product
design and assembly processes, Knowledge-based tools for creating process plans,
and a DELMIA-CENIT solution for 3D laser cutting.
