This preliminary financial update is intended to inform all interested parties of Actel's current expectations for the second quarter of 2008. This update is made as of April 29, 2008, pursuant to the safe harbor provisions of the Public Securities Litigation Reform Act of 1995 and should be read with the "Risk Factors" in Actel's most recent Form 10-Q or 10-K, which can be found on Actel's web site, www.actel.com.

Actel's quarterly revenues and operating results are subject to a multitude of risks, including general economic conditions and a variety of risks specific to Actel or characteristic of the semiconductor industry, such as fluctuating demand, intense competition, rapid technological change and related intellectual property and international trade issues, wafer and other supply shortages, and booking and shipment uncertainties. These and the other Risk Factors make it difficult for Actel to accurately project quarterly revenues and operating results, and could cause actual results to differ materially from those projected in the forward-looking statements. Any failure to meet expectations could cause the price of Actel’s stock to decline significantly.
