               Yantai Raffles Shipyard Chooses Product Lifecycle
                   Management Solutions from IBM and Dassault
                Systemes for Competitive Shipbuilding Advantage


  Premier offshore builder of ships and oilrigs adopts solutions to become the
              most efficient and economical shipyard in the world

Yantai, China and Paris, France - July 24, 2003 - IBM and Dassault Systemes
(Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today announced the signing of a
contract with Yantai Raffles Shipyard (YRS) for product development and data
management software. YRS has acquired IBM's Product Lifecycle Management (PLM)
Shipbuilding Solutions with software developed by Dassault Systemes in its aim
to become one of the most efficient and low cost shipyards in the world.

The PLM Solution fulfills YRS' critical need for web-based product development
collaboration to link its shipyard in Yantai, China with its headquarters in
Singapore and its offices in Houston, Texas, USA. With the integrated IBM PLM
platform, comprised of CATIA V5 for collaborative virtual product development
and ENOVIA LCA and ENOVIA Portal 3d com for real-time product data management
developed by Dassault Systemes, YRS is already realizing the benefits of
seamless sharing of all vessel lifecycle information between product development
teams in the company.

The advanced PLM solution has enabled the shipyard to streamline design
processes for all its vessels, from floating storage and off-take (FSO) ships to
oilrigs and luxury yachts. YRS is already experiencing substantial return on
investment through lower material costs and improved quality - a combined
competitive advantage.

"Our customers deserve the best and we give them the best. Our prices are very,
very competitive against any shipyard in the world and we sell on good quality
and delivery. This is only possible if we use the best technology on the market
to build our ships and that's why we chose IBM PLM solutions," said Brian Chang,
Chairman/CEO, YRS. "Today, we are able to collaborate with owners, suppliers and
designers in an exciting new way. Being able to vision a digital model of a ship
before production begins is an unforgettable experience for our customers. PLM
technology from IBM and Dassault Systemes is shaping the way suppliers, partners
and clients think about us."

IBM and Dassault Systemes' CATIA V5 solution comes with a full set of
shipbuilding-oriented functionalities to meet YRS' requirements, from
'conceptual' to 'detail ship design' and 'in production'. Powerful digital
mock-up technology and a collaborative design environment ensure that YRS
engineers design efficiently and with precision. ENOVIA LCA and ENOVIA 3d.com
solutions enable full collaborative product development, as well as



access to both design information and engineering data among the YRS marketing,
engineering and production functions, and ensures that YRS staff, customers,
partners and suppliers are able to work together in a virtual product
development environment.

"With PLM solutions from Dassault Systemes, Yantai Raffles can simulate all
design processes, from the pre-project phase, through detailed design, analysis,
simulation, assembly and maintenance in order to avoid conception and fitting
errors," said Etienne Droit, executive vice president, Sales and Marketing,
Dassault Systemes. "YRS can also establish pervasive 3D-based communication and
collaboration between its sites in Singapore and China. Simulation of the entire
product life cycle before committing to physical production helps accelerate the
shipbuilding process, eliminate design mistakes and cut costs."

                 Product Lifecycle Management Solutions from IBM
               and Dassault Systemes Boost Efficiency at Leading
                          Premium Vehicle Manufacturer

      BMW Group expects a reduction in development time and an increase in
  operational and financial efficiencies - Several hundred BMW Group suppliers
        will adopt the same world-leading collaborative design solution


Munich, Germany and Paris, France - July 24, 2003 - IBM and Dassault Systemes
(Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today announced that BMW Group,
one of the world's most profitable car manufacturers and leader in the premium
vehicle market, is developing a new vehicle program with IBM Product Lifecycle
Management technology with software from Dassault Systemes. The powerful
solution is helping BMW Group to streamline product development and contain
costs.

IBM PLM Solutions, with CATIA(R) V5 for collaborative product development and
ENOVIA(TM) for product data and lifecycle management developed by Dassault
Systemes, will enable BMW Group to reuse standard vehicle components to create
multiple variants that can be used from one model to the next. Integrating all
product information throughout the vehicle development lifecycle, the new PLM
platform is set to boost operational efficiency, increase collaboration between
development teams, reduce time to market, and ultimately deliver better premium
vehicles for increased customer satisfaction. The two-year rollout represents a
significant IT investment by the BMW Group.

IBM has also been engaged in an extensive CATIA V5 rollout program to integrate
BMW Group suppliers with the PLM platform. Several hundred suppliers
contributing to BMW's new car program will be equipped with IBM PLM Solutions by
the end of 2004. This collaboration will enable material suppliers to
significantly improve efficiency by reacting to the design changes that are
customary in new vehicle development far earlier in the product development
cycle and eliminate unnecessary time delays that translate into costs.

Long-time partners with BMW Group for product development, IBM and Dassault
Systemes' team of consulting professionals are supporting BMW Group to
revolutionize the way a car is conceived and developed. With world-class PLM
tools and industry expertise, BMW Group continues to strive for the optimum
development process across all domains.

BMW Group is now prepared to develop entire vehicles virtually, which are the
basis for complete virtual validations, i.e., crash test and other vehicle
safety and performance simulations, significantly reducing the need for costly
physical prototypes. Anticipated benefits include a significant reduction in
both development time and cost via a process which facilitates faster and more
innovative design.

CATIA V5 will be used to create a digital master car model that can be used to
develop a full family of vehicles. ENOVIAVPM will run concurrently with CATIA V5
and CATIA V4 for total integration of vehicle design and manufacturing
information. It will also enable BMW Group




to efficiently manage all vehicle-related information - linking common
standards, processes, applications and methodology.

"We have been working with BMW for more than twenty years. During that time, we
have studied their development processes, listened to their engineers, and
together come up with PLM solutions that perfectly fit BMW Group's development
strategy. It's a win-win relationship built on trust and respect that has helped
BMW Group, Dassault Systemes and IBM become leaders in their respective
domains," said Bruno Latchague, Executive Vice president, Development and
Support, Dassault Systemes and Dr. Manfred Sammet, IBM PLM Management Executive
for the BMW digital car program.

Cars from the other BMW Group brands, MINI and Rolls Royce, are also developed
using IBM PLM Solutions.
