SIERRA STUDIOS TO INCORPORATE 3DEEP TECHNOLOGY INTO HOMEWORLD

Bellevue, WA (July 27, 1999) - Sierra Studios announced today that it will integrate Sonnetech, Ltd.'s, 3Deep technology into their highly anticipated PC game, Homeworld, due to ship this September. Through this strategic partnership with Sonnetech, Sierra Studios is leading the industry with their early adoption of the 3Deep technology.

3Deep is the first simple, absolute-gamma-correction software for 3D games and graphics. Inaccurate gamma settings are responsible for "washed out" or "too dark" images seen on many computer games. 3Deep provides a consistent and high-quality solution for delivering accurate lighting and shading effects in the graphic renderings of today's PC titles.

"Working with Sonnetech has been a great experience," said Jim Veevaert, director of marketing for Sierra Studios. "I didn't think it was possible, but Sonnetech's 3Deep technology really makes Homeworld look even more amazing on any given computer screen."

Sonnetech, Ltd. is an innovator in color matching and other software for enhancing computer displays, video cards, web browsers, digital cameras, and printers. Sonnetech has sold more than 10 million copies of Colorific® and 3Deep™ to date through OEM relationships with major monitor, video card, and printer manufacturers, as well as through retail channels.
