E&S Awarded $9.7M in Orders for CATT Upgrade Programs

ORLANDO, FLORIDA, April 3, 2006, Evans & Sutherland Computer Corporation (E&S) (NASDAQ: ESCC) announced today that it has been awarded follow-on orders in the amount of $9.7M by the U.S. Army's Program Executive Office for Simulation, Training, and Instrumentation (PEO-STRI) to update and provide additional visual systems for its Combined Arms Tactical Training (CATT) Programs.

The new orders call for an additional 221 EPX™-50 systems with over 1500 channels. More than 370 systems, which are composed of approximately 3000 PC-based visual channels, have already been fielded. E&S's EPX-50 image generator was originally selected as a result of a rigorous competitive evaluation of a number of PC-based solutions. EPX-50 uses E&S’s revolutionary Environment Processor software with military extensions (EPX) and runs on standard PC hardware equipped with state-of-the-art commercially available graphics accelerators.

E&S Simulation Systems General Manager Nick Gibbs said, “We are very pleased to be selected for the follow-on CATT programs. We successfully delivered over 3,000 PC’s on schedule to CATT, and we are working hard to ensure that the additional units also deliver on time. The EPX-50 continues to deliver on the promise of advanced PC-based simulation and continues to outperform all other products in its class with the highest possible image quality and hardware reliability.”

About EPX

Evans & Sutherland's Environment Processor with military extensions is designed to deliver flexibility, responsiveness, and performance for the most demanding training requirements. EPX software runs on hardware with a range of prices and capabilities, allowing customers to select the right hardware platform for their specific training missions. The unique, layered architecture of the software enhances reliability and allows rapid database creation and update from source materials. Since EPX databases can be delivered as source data, the same data can be used in multiple applications and updated incrementally as new source materials become available. EPX offers ESIG®/CIGI host compatibility, which makes it easier to upgrade existing simulators to the new visual system. In addition, all EPX products are offered with a 3D whole-earth terrain model with three high-resolution insets to allow training to begin immediately.
