Sabena Flight Academy to Upgrade Simulator with E&S Visuals

SALT LAKE CITY, UTAH, January 6, 2004, Evans & Sutherland Computer Corporation (E&S ) NASDAQ: ESCC) announced today that Sabena Flight Academy (SFA) will upgrade its B737-300/400/500 simulator with E&S's ESIG -3350GT image generator and six monitor replacement projectors. The upgrade, which will be completed in the third quarter of 2004, represents the fourth ESIG system to be installed at SFA's training center in Brussels, Belgium.

"We have been very pleased with the performance of E&S and the company's products in the past, and we are happy to be continuing our relationship," said Jean Read, President and CEO of Sabena Flight Academy. "As a third-party training provider, it is most important for us to maintain the highest level of simulator performance and reliability because our simulators are often in use 24 hours per day, and with E&S, we know we have a supplier who will deliver."

"When we began marketing our products directly to the airlines a number of years ago, Sabena was our very first customer," said David Rushton, General Manager of E&S Computer Ltd. "Since then, we have maintained a strong bond, supplying visual systems for all of their new flight simulators."

Evans & Sutherland's ESIG image generators are the most widely sold image generators in the world. The ESIG-3350GT provides up to 1.5 million pixels to each projector at a 60Hz update rate. In addition, the ESIG-3350GT ensures a low cost of ownership, with reliability and an easy, cost-effective upgrade path.
