Actel Receives Additional Nasdaq Notice

Market Wire, November, 2007

Actel Corporation (NASDAQ: ACTL) today announced that it received, on November 13, 2007, a notice from The Nasdaq Stock Market ("Nasdaq") of an additional Staff determination that the Company is not in compliance with the requirement for continued listing set forth in Nasdaq Marketplace Rule 4310(c)(14), under which listed companies must file with the Securities and Exchange Commission ("SEC") all required reports. Actel's noncompliance is a result of the ongoing review of its historical stock option grant practices and related failure to file with the SEC a Quarterly Report on Form 10-Q for the fiscal quarter ended September 30, 2007.

As previously announced, Actel already received notices from Nasdaq of Staff determinations that the Company is not in compliance with Rule 4310(c)(14) due to Actel's failure to file with the SEC a Quarterly Report on Form 10-Q for the quarter ended October 1, 2006, an Annual Report on Form 10-K for the fiscal year ended December 31, 2006 ("Form 10-K"), a Quarterly Report on Form 10-Q for the quarter ended April 1, 2007, and a Quarterly Report on Form 10-Q for the quarter ended July 1, 2007. Actel also already received notice from Nasdaq of a Staff determination that the Company is not in compliance with the requirements for continued listing set forth in Nasdaq Marketplace Rules 4350(e) and 4350(g), under which listed companies must hold an annual meeting of shareholders, solicit proxies, and provide proxy statements to Nasdaq. Actel did not hold an annual meeting of shareholders during 2006 because of the stock option review.

On February 16, 2007, a Nasdaq Listing Qualifications Panel ("Panel") granted Actel's request for continued listing. On May 18, 2007, the Panel determined to delist the Company's securities, but stayed the delisting pending further action by the Nasdaq Listing and Hearing Review Council ("Listing Council"). On April 2, 2007, the Listing Council stayed the Panel's decision pending a review by the Listing Council. On August 23, 2007, the Listing Counsel granted the Company an extension until October 22, 2007, to demonstrate compliance with all continued listing requirements. On October 17, 2007, the Nasdaq Board of Directors (the "Nasdaq Board") called for review the August 23, 2007, decision of the Listing Council, and stayed the suspension of Actel's securities from trading, pending further consideration by the Nasdaq Board. On November 9, 2007, the Nasdaq Board granted the Company an extension until January 9, 2008, to file all delinquent periodic reports necessary to regain compliance with the filing requirement contained in Rule 4310(c)(14).

Stock Option Review

As previously announced:

--  A Special Committee of Actel's Board of Directors, composed of
    independent directors and assisted by independent counsel, was appointed on
    September 22, 2006, to review the Company's historical stock option grant
    practices and related accounting.  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 Actel on February 1, 2007.  On March 9, 2007, the Special
    Committee delivered its final report to the Board of Directors.

--  Actel voluntarily informed the staff of the SEC about the internal
    review.  On May 23, 2007, the staff indicated that it had closed its file
    and would not recommend any enforcement action by the SEC.

--  On January 18, 2007, Actel's management concluded that shareholders
    and other investors should no longer rely on the Company's financial
    statements and the related reports or interim reviews of Actel'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.  Actel's management has
    also concluded that the Company needs to restate its historical financial
    statements to record additional non-cash and potentially other charges
    related to past stock option grants.

--  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 SEC to restate financial statements, Actel intends to include in its
    Form 10-K the comprehensive disclosure outlined in guidance posted by the
    SEC Chief Accountant's Office on January 16, 2007.
    

The Company intends to file its delinquent SEC periodic reports, including any required restatements, and solicit proxies and hold an annual shareholders' meeting as soon as practicable.

Certain statements in this release are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995, including statements regarding Actel's intentions. Actual results may differ materially from those indicated in the forward-looking statements.

Other potential consequences include modifications in the amount and timing of previously awarded stock-based compensation; the recording of additional expenses, including the recording in past periods of expenses that were deemed immaterial at the time and the recording in the 2006 fiscal year of expenses that would ordinarily have been subsequent events; claims and proceedings relating to such matters, including shareholder litigation and action by the SEC and/or other governmental agencies; and negative tax or other implications resulting from any accounting adjustments or other factors. There can also be no assurance that Nasdaq will continue to list Actel's Common Stock.
