Santa Barbara, CA. May 23, 2002 -- Green Hills Software, Inc., the world's fastest growing and now second largest real-time operating systems (RTOS) company, announced today that rival Wind River Systems, Inc., (NASDAQ: WIND) has abandoned its lawsuit alleging patent infringement by Green Hills Software for its EventAnalyzer™ and MULTI® IDE products. Wind River's withdrawal was unilateral, and without accommodation from Green Hills Software.

Green Hills Software's EventAnalyzer™ product is a powerful graphical embedded development tool for capturing and displaying event timelines that enables developers to study system events such as context switches and semaphores, and user-defined application events. The EventAnalyzer can be used with Green Hills Software's royalty-free, secure INTEGRITY® RTOS, the small-footprint, royalty-free ThreadX® RTOS, or a user's proprietary RTOS.

"Wind River's action was totally without merit. They dropped the lawsuit just two days before we were scheduled to file our response to their complaint with the court! As I said after they filed the lawsuit over six months ago, this was just a scare tactic," commented Dan O'Dowd, Green Hills Software's President and CEO. "We developed our EventAnalyzer product entirely ourselves, without reliance on any technology patented by Wind River Systems or anyone else. We were confident we would win a total victory in court. At the last minute, they just chickened out."

Wind River filed the lawsuit against Green Hills Software in October, 2001, and simultaneously issued a press release announcing the lawsuit. The announcement was widely distributed by Wind River, and was reported by the major news services at the time. Immediately after the Wind River lawsuit was filed, Green Hills Software issued a press release denying all of Wind River's claims (http://www.ghs.com/news/archive/211008pr.html). After months of legal procedure, and without receiving any accommodation from Green Hills Software, Wind River notified the court that they were withdrawing their claim. This unilateral withdrawal by Wind River ends all legal activity with regard to their claim. Now, with this Wind River Systems retreat, the unsubstantiated allegations made against Green Hills Software have been withdrawn, and Green Hills Software is free to continue to offer its EventAnalyzer and MULTI products.

O'Dowd continued, "The honorable thing for them to do at this point is to issue a retraction, publicize it in the same manner as their unfounded allegations, and attempt to set the record straight. But I doubt that they will do this because they don't want to call attention to the fact that we have been rapidly capturing their market share."
