Doug Schatz, chairman and chief executive officer, said, “We are pleased to report 58 percent sequential growth in revenue, and a lower net loss for in the second quarter of 2002. The strength was driven primarily by sales to our US-based semiconductor capital equipment OEM customers, emphasizing our strong technological position and design-win momentum.

“Visibility remains limited due to uncertainty in end market demand, driven by the anticipated slower rate of recovery in PC, consumer electronics and telecommunications markets. Given this uncertainty, we are implementing stringent cost containment and reductions measures, while still investing in the critical areas necessary to meet our strategic goals,” said Mr. Schatz.

Based on information currently available, the Company expects third quarter revenues in the $68 million to $70 million range and a loss per share of $0.10 to $0.12 cents, before any one time charges.
