ATLANTA -- ImaGen Offers Ideal Imaging Platform for Today's Simulation and Modeling Applications; Solution to be Used by a Top Ten Supplier to the U.S. Department of Defense

Concurrent Computer Corporation (NASDAQ: CCUR), Integrated Solutions Division, a leading provider of integrated computer solutions for mission-critical applications, today announced that its ImaGen(TM) image generation (IG) solution has been chosen by Diamond Visionics to deliver the highest levels of computer-generated image quality and fidelity to a top ten supplier to the U.S. Department of Defense.

Concurrent's ImaGen platform features the latest, industry-standard components from leading graphics suppliers, ensuring that application developers will have access to the best possible COTS IG solutions. ImaGen servers feature multiple Intel(R) Xeon(TM) or AMD Opteron(TM) processors and a range of tower or rackmount enclosures. ImaGen can be configured with a choice of powerful dual-monitor-capable graphics controllers, and in this instance will utilize the latest NVIDIA 6800 graphics card. Typical ImaGen imaging applications include civil and military simulation, mission planning, homeland security, scientific and medical visualization, architectural design, energy exploration and entertainment.

"Our initial experience with Concurrent's ImaGen platform demonstrated unparalleled performance and reliability," said Graham Upton, vice president of New Business Development at Diamond Visionics "We are contracted by a world leading aerospace company, and Concurrent not only delivered a premier platform for those simulation needs, but further demonstrated their commitment with an expeditious two-week turnaround. We look forward to continuing to build on our relationship with Concurrent."

"Diamond Visionics is a respected leader in real-time visual solutions, and our ImaGen visual platform was able to meet their stringent requirements for real-time deterministic, high-fidelity performance to ensure the most realistic training experience possible," said Gary Beerman, director of Marketing, Concurrent Integrated Solutions Division. "Concurrent is committed to providing a powerful system that also remains flexible to our customers' needs in the simulation and training industry, and the ImaGen platform is quickly proving its capabilities."
