FOR IMMEDIATE RELEASE

                       Delmia Corp.'s Academic Partnership
                      with Oregon State University Provides
                State of the Art Simulation Software to Students


Troy, Mich. - January 21, 2003 - Digital manufacturing solutions provider Delmia
Corp., a Dassault Systemes company (Nasdaq: DASTY: Euronext Paris: #13065,
DSY.PA), today announced it has entered into an academic partnership with Oregon
State University, through which it will provide simulation software to the
university at a highly discounted cost. DELMIA's IGRIP(R), a robotic and
workcell simulation solution, and DPM Assembly(R), a process detailing and
validation tool, will be utilized for graduate coursework in the school's
Industrial and Manufacturing Engineering (IME) program, as well as for various
research and design projects.

Oregon State is also using Quest(R), DELMIA's complete 3D process analysis and
discrete event simulation software, and Envision/Ergo(TM), a human motion and
task analysis solution, in the school's Global Digital Enterprise Research
Laboratory (GDERL), an international collaboration between OSU and the
University of Durham in the United Kingdom. The lab focuses on the development
of Digital Enterprise Technology (DET) research and education, and provides
graduates with highly relevant skill sets and enabling projects for technology
exploration.

According to Dr. Bill Reiter at Oregon State, "Delmia Corp.'s leading-edge,
industrial grade software is widely used in our job market, and we feel strongly
that students should be exposed to it to better prepare them for what they will
be encountering in the workplace. The academic partnership with Delmia Corp. has
allowed us to purchase a whole classroom of seats to help us meet this
objective."

Reiter continued, "3D motion visualization is the number one reason we use
DELMIA software. While visualization is non-traditional in the world of
mechanical engineering, we are trying to change that paradigm because the
problems that are so common in design situations are much easier to address by
visualizing than by solving analytically."

"Oregon State's program has pioneered the educational use of DELMIA software on
the West Coast," said Roy Smolky, DELMIA Academic Partner Program (DAPP)
coordinator. "Their leadership role has impacted major employers like
Freightliner and Boeing, where they have placed many interns to work on projects
utilizing our software."

Oregon State's IME program is a unique discipline that draws on knowledge from
the physical, information, and human sciences. Students apply engineering
methods to design, implement, operate and improve systems to deliver
high-quality products and services. Recognizing that both industrial and
manufacturing engineering are critical growth areas for future technical
education and research, the program's mission is to prepare students to be
future leaders in engineering, business, and industry.

In addition to the Oregon State University academic partnership, Delmia Corp.
has entered into recent agreements to supply its software to higher educational
institutions such as the University of Michigan, Oakland Community College, Lake
Superior State University, Mississippi State University, Georgia Institute of
Technology (Georgia Tech), Heart of Georgia Technical College, Purdue
University, and Western New England College.

            IBM and Dassault Systemes Help TECO Electric & Machinery
                      Ltd. Cut Product Design Time by 50%

     Worldwide industry leading motor manufacturer uses CATIA V5 to enhance
                design capability and maintain competitive edge

Taipei, Taiwan and Paris, France - January 21, 2003 - TECO Electric & Machinery
Ltd. (TECO), worldwide industry leading motor manufacturer, IBM, and Dassault
Systemes (Nasdaq: DASTY, Euronext Paris: #13065, DSY.PA) today announced that
TECO's successful migration to CATIA V5, a core application of IBM's Product
Lifecycle Management portfolio developed by Dassault Systemes, has shortened its
product design time by 50% over the last year.

TECO migrated from a 2D CAD system to CATIA Version 5, the world's leading
Product Lifecycle Management solution for collaborative product development, in
2001. In addition to its Chung-Li factory in Taiwan, TECO is also deploying
CATIA V5 in China and Indonesia. By implementing CATIA V5, TECO has been able to
combine virtual product design and manufacturing, and cut the development time
of its motor products in half.

"The key feature that helped us reduce production time is CATIA V5's ability to
simulate the entire product lifecycle," said Daniel Shih, technical executive &
general manager Overseas Industrial Products Business Division, TECO. "Thanks to
this, time previously spent on design, data sharing, and data transfer was
reduced, while the number of errors during the design process were also cut
down. In addition, the seamless migration from our 2D CAD system enabled us to
maintain the high levels of quality and efficiency in our design process."

"More and more customers who recently migrated to IBM's PLM platform, such as
TECO, are declaring dramatic savings in design time and increased economies,"
said Raoul Van Engelshoven, vice president, IBM Product Lifecycle Management
Asia-Pacific. "At IBM PLM, we are committed to ensuring manufacturing customers
reap the benefits that PLM and e-collaboration have to offer. We will continue
to provide our customers with powerful solutions and services to keep them ahead
of the competition, while strengthening their bottom line."

"As one of the world's leading motor manufacturers, it is vital for TECO to
continually seek to improve in its product design and development processes,"
said Francis Bernard, executive committee advisor, Dassault Systemes. "CATIA V5
has helped TECO cut down both production time and costs and we look forward to
developing future solutions that provide further competitive advantages."

Product Lifecycle Management, coined by IBM and Dassault Systemes in 1999 during
the emergence of strategic product-centric business processes, helps companies
manage every stage of a product's lifecycle, allowing e-collaboration across
geographic boundaries, both internally by all product-related functions and with
suppliers and customers, from initial product conception through to after-sales
maintenance. PLM solutions from IBM and Dassault Systemes help manufacturers of
all types innovate, improve quality, and reduce both costs and product
development times.
