SGI Launches Virtual Science Network, Providing Content for Immersive Environments in Museums Around the World

Journeys through the Solar System, Virtual Tours of the Human Body and
Walk-Throughs of Petroleum-Bearing Strata under the Seabed All Accessible
through the Virtual Science Network

Glasgow, Scotland (March 6, 2002)-SGI (NYSE: SGI) today launched the Virtual
Science Network, an international alliance of museums, science centers and
research organizations intended to transform leading scientific discoveries
into compelling visual experiences for the general public.

Launch ceremonies were held at the Glasgow Science Centre, a network member
that houses the first-ever immersive theater within a science center in
Europe. Lockheed Martin and the Smithsonian Institution’s National Air and
Space Museum are among the many other founding members.

The Virtual Science Network enables museums and science centers to access
and share new content from peers around the world for their own immersive
environments, creating a new conduit of knowledge flow between science
research and science outreach. Participating companies and researchers are
able to make their leading work available within a structured framework with
protection for intellectual property, while museums and science centers
fulfill their mandate to present science to their audiences compellingly.

“Being one of the first nodes for science outreach in Europe, we are
extremely excited to be a part of this network,” said Phil Lavery, digital
media manager, Glasgow Science Centre. “Keeping an exhibit updated and
pertinent to today’s breakthrough research is what science museums have
needed for a long time. Now we finally have a formula that will work.”

Other museums and science centers have expressed interest in participating,
and discussions are under way with some of the world’s leading institutions
and corporations to become content providers for educational outreach. “We
are interested in joining the Virtual Science Network,” explained Dieter
Isakeit, International Space Station User Information Centre manager,
Directorate of Manned Spaceflight and Microgravity, European Space Agency.
“We expect that, without putting intellectual property rights at risk, it
will allow us to share more easily our already-existing applications-such as
a virtual walk-through of the International Space Station-with science
centers and educational institutions in Europe and the world.”

“Museums and science centers need access to leading science,” added Walter
Stewart, director, Global Marketing, Research and Education, SGI. “At the
same time, researchers benefit from public recognition and understanding of
their work. The Virtual Science Network meets both needs and ensures that
the public will have unprecedented access to an understanding of
groundbreaking science.”

Lockheed Martin will provide content about the sun obtained using the solar
telescope that the company delivered for the Transition Region and Coronal
Explorer (TRACE), a NASA mission launched in 1998. The National Air and
Space Museum will share “Earth Today,” currently on display in Washington,
D.C. Helping audiences understand the relationships that exist within the
world’s geosphere, atmosphere, hydrosphere and biosphere, this fascinating
exhibit includes a 10-foot diameter, high-resolution image of the Earth that
is frequently updated to indicate the latest international environmental
conditions.

SGI’s customers include many of the world’s greatest science centers,
planetariums and museums, using visualization to offer high-resolution
imagery and interactive capabilities in theater settings. Increasingly, such
institutions are installing SGI(r) Reality Center(tm) facilities designed to
immerse users in virtual environments so they can explore, understand and
communicate about data in ways not possible in the physical world. Further
