Transitive's QuickTransit Software Broadens Application Support for New Silicon Graphics Prism Visualization System for Linux.

LOS GATOS, Calif. -- Independent Software Vendor Opticore First to Certify Applications Using QuickTransit(TM)

Transitive Corporation, the leading provider of software that enables transportability of applications across multiple processor and operating system pairs, today announced that Silicon Graphics, Inc. (NYSE:SGI) will begin shipping Transitive's QuickTransit(TM) software on its new Silicon Graphics Prism(TM) advanced visualization system in early 2005. QuickTransit, which Transitive launched one month ago, allows software applications compiled for one processor and operating system to run on another processor and operating system without any source code or binary changes.

Silicon Graphics Prism is the world's first complete advanced visualization system for Linux(R), bringing unprecedented visualization capability to the open source community. QuickTransit enables Silicon Graphics Prism users to transparently run any application that currently runs on SGI(R) systems based on the MIPS(R) processor and IRIX(R) operating system on the new system, which is based on the Intel(R) Itanium(R) 2 processor and Linux(R) OS. QuickTransit also retains full functionality and performance levels that typically exceed native speeds on existing MIPS platforms. As a result, QuickTransit significantly accelerates the availability of a broad range of independent software vendor (ISV) and customer-written applications on the Silicon Graphics Prism. Therefore, existing SGI customers can more easily migrate to the Silicon Graphics Prism and take advantage of its improved performance and new features. New customers will also benefit from the increased application support provided by QuickTransit.

"SGI is the first of several major customers that Transitive will announce over the coming months," said Bob Wiederhold, President and CEO of Transitive Corporation. "The Silicon Graphics Prism is state-of-the-art for visualization applications and demonstrates that QuickTransit can provide the functionality and performance necessary to quickly bring a large number of ISV and customer-written applications to new platforms, thereby making these platforms significantly more attractive to end-customers."

"QuickTransit software allows us to dramatically accelerate application availability on the Silicon Graphics Prism, delivering significant value to our customers who demand the increased performance expected from a Silicon Graphics system," said Simon Hayhurst, Product Line Manager, Visual Systems Group at SGI.

SGI will begin shipping QuickTransit software to its customers by early 2005 as a standard component of the Silicon Graphics Prism. Existing SGI customers will be able to download QuickTransit to their platforms at that time. End-users will be able to use QuickTransit free of charge for 30 days at which point they will be required to license the product from SGI for continued use.

Opticore is First ISV to Support QuickTransit

SGI and Transitive are working closely with ISVs to attain full certification of their applications on the Silicon Graphics Prism through QuickTransit. QuickTransit allows ISVs to quickly provide a fully functional, high-performance solution on the Silicon Graphics Prism, while circumventing the often lengthy and expensive process of completing a full native port. ISVs have found QuickTransit to be an invaluable tool to accelerate their support of Silicon Graphics Prism. Opticore is the first ISV to publicly announce certification of their applications through QuickTransit. Additional ISVs are expected to announce certification over the coming months.

"QuickTransit has enabled us to deliver increased performance and outstanding capabilities on Silicon Graphics Prism with a rapid and easy certification process that required no source code or binary changes," said Lars Pettersson, CEO of Opticore.
