As previously disclosed, a Special Committee of the Board of Directors of Actel Corporation (“Actel” or “the Company”), composed of independent directors and assisted by independent counsel, was formed to review the Company’s historical stock option grant practices and related accounting. On January 18, 2007, Actel’s management concluded that the Company’s financial statements and the related reports or interim reviews of the Company’s independent registered public accounting firm and all earnings press releases and similar communications issued by the Company for fiscal periods commencing on or after January 1, 1996, should no longer be relied upon. On January 30, 2007, the Special Committee presented its preliminary findings to the Board of Directors. The preliminary findings were described in a Current Report on Form 8-K filed by the Company on February 1, 2007. On March 9, 2007, the Special Committee delivered its final report to the Board of Directors.

Working with its independent registered public accounting firm, the Company is evaluating corrections to measurement dates and other related accounting issues and is quantifying the financial and tax impact of those inaccuracies and corrections. In lieu of amending its prior filings with the Securities and Exchange Commission (“SEC”) to restate financial statements, the Company intends to include in its Annual Report on Form 10-K for the year ended December 31, 2006, the comprehensive disclosure outlined in guidance posted by the SEC Chief Accountant’s Office on January 16, 2007.

As also previously disclosed, Actel has received notices from The Nasdaq Stock Market (“Nasdaq”) of Staff determinations that the Company is not in compliance with the requirement for continued listing set forth in Nasdaq Marketplace Rule 4310(c)(14), which requires listed companies to file with the SEC all required reports, and Rules 4350(e) and 4350(g), which require listed companies to hold an annual meeting of shareholders, solicit proxies, and provide proxy statements to Nasdaq. On February 16, 2007, a Nasdaq Listing Qualifications Panel (“Panel”) granted the Company’s request for continued listing, subject to certain conditions. On April 2, 2007, the Nasdaq Listing and Hearing Review Council (“Listing Council”) stayed the Panel’s decision pending a review by the Listing Council of the merits of the Panel’s decision. The Nasdaq Listing Qualifications Department will provide the Listing Council with an updated qualifications summary sheet and any additional information that staff believes would assist the Listing Council in its review of this matter by June 20, 2007. The Company may submit any additional information that it wishes the Listing Council to consider by June 29, 2007.
