~~The~~On ~~consummation of the Offer will be conditioned on the satisfaction of customary closing conditions~~October 15, ~~including~~2010, ~~among~~Actel ~~others,~~Corporation. (i“Actel”) ~~that~~ atissued ~~least~~ a press ~~majority~~release ofannouncing ~~then~~its ~~issued~~financial ~~and~~results ~~outstanding~~for ~~Shares having been validly tendered into (and not withdrawn from)~~ the ~~Offer~~third ~~prior~~fiscal toquarter ~~the~~ended ~~expiration date of the Offer (such percentage~~October 4, ~~the “Minimum~~2010. ~~Condition”);~~The ~~(ii) the~~full ~~expiration~~text ~~or termination~~ of ~~any applicable waiting period under~~ the ~~Hart-Scott-Rodino~~press ~~Antitrust~~release ~~Improvements~~is ~~Act~~attached ofhereto ~~1976,~~ as ~~amended,~~Exhibit ~~and~~99.1 ~~the receipt of any other required consents or approvals of any governmental authority of competent jurisdiction under antitrust laws;~~ and ~~(iii) that the other conditions set forth in Annex A to the Merger Agreement have been satisfied or waived. The Offer~~ is ~~not~~incorporated ~~subject~~herein toby ~~any financing condition~~reference.

~~If,~~Item at any expiration date of the Offer, all of the conditions to the consummation of the Offer (including the Minimum Condition) have been satisfied or waived, but the number of Shares validly tendered in the Offer and not properly withdrawn is less than that number of Company Shares which, when added to the number of Shares that may be issued pursuant to the Top-Up Option (as defined below) in compliance with the Merger Agreement, would represent at least one Share more than 90% of the Shares then outstanding, then upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with applicable law, Purchaser may elect to reduce the Minimum Condition to a number of Shares such that following the purchase of Shares in the Offer, Parent and its wholly owned subsidiaries, including Purchaser, would own 49.9%.01. ofFinancial ~~the~~Statements ~~then outstanding Shares (the “Reduced Purchase Amount”)~~ and ~~purchase, on a pro rata basis based on the Shares actually deposited in the Offer by each such holder of Shares, Shares representing the Reduced Purchase Amount~~Exhibits.

Following the consummation of the Offer, subject to customary conditions (including receipt of the requisite approval of the Company’s shareholders, if required under applicable law), Purchaser will be merged with and into the Company (the “Merger”) and the Company will become a wholly owned subsidiary of Parent. At the effective time of the Merger (the “Effective Time”), each outstanding Company Share (other than Shares held by the Company, Parent or Purchaser or their respective subsidiaries and Shares held by shareholders who properly demand and perfect dissenters’ rights under California law) will be converted into the right to receive an amount equal to the Offer Price, on the terms and subject to the conditions of the Merger Agreement.

Pursuant to the Company’s equity incentive plans and the terms of the Merger Agreement, restricted stock units, stock options and stock appreciation rights outstanding immediately prior to the Effective Time, whether or not vested, of continuing employees and continuing service providers will be assumed by Parent (except to the extent restricted stock units become vested at the Effective Time) (“Continuing Awards”) and converted into awards for Parent’s common stock rounded down to the nearest whole share after being multiplied by an exchange ratio (equal to the Offer Price divided by the average of the closing sales prices of Parent’s common stock on the NASDAQ Global Market the five trading days immediately preceding and not including the Effective Time) and the exercise price, if any, of such Continuing Award will be divided by the exchange ratio. The Company’s restricted stock units, stock options and stock appreciation rights outstanding immediately prior to the Effective Time that are not Continuing Awards be cancelled as of the Effective Time and, to the extent the award has an exercise price less than the Offer Price, will be converted into the right to receive an amount in cash equal to the Offer Price less any applicable exercise price and all applicable deductions and withholdings required by law.

If immediately following the successful consummation of the Offer Purchaser holds, together with all shares held by Parent, at least 90% of the then-outstanding Shares in the Offer (the “Short-Form Merger Threshold”), then Parent and Purchaser will consummate the Merger pursuant to the short form merger procedures under the California law as soon as practicable thereafter without a vote or any further action by the holders of Shares.

The Company has also granted to Parent and Purchaser an irrevocable option (the “Top-Up Option”), exercisable only in accordance with the terms and subject to the conditions set forth in the Merger Agreement, to purchase at a price per Company Share equal to the Offer Price, up to that number of newly issued Shares (the “Top-Up Option Shares”) equal to the lowest number of Shares that, when added to the number of Shares collectively owned by Parent or Purchaser at the time of exercise, will constitute one Company Share more than 90% of the Shares, calculated on a fully diluted basis as set forth in the Merger Agreement; provided, however, that the Top-Up Option will not be exercisable for Shares in excess of the number of Shares authorized and unissued or held in the treasury of the Company. The Top-Up Option shall not be exercisable unless, immediately after such exercise and the issuance of Shares, Purchaser, together with Parent, would hold one Share more than 90% of the then outstanding Shares.

If immediately following the successful consummation of the Offer and assuming exercise in full of the Top-Up Option, Parent, Purchaser and their respective wholly owned subsidiaries would own less than 90% of the Shares then outstanding (after giving effect to the exercise in full of the Top-Up Option), Purchaser may, but is not required to, in order to seek additional Shares and facilitate the consummation of the Merger using such short form merger procedures, provide for a “subsequent offering period” (and one or more extensions thereof) under federal securities law and in accordance with the Merger Agreement following such successful consummation of the Offer of not less than three nor more than 20 business days in the aggregate.

If immediately following the successful consummation of the Offer, Purchaser holds, together with all Shares held by Parent, less than 90% of the then outstanding Shares (and the “subsequent offering period” provided by Purchaser, if any, and the exercise, if permitted under the Merger Agreement, of the Top-Up Option described above), Parent and the Company must obtain the approval of the Company’s shareholders holding a majority of the outstanding Shares to approve the principal terms of the Merger prior to consummating the Merger. In this event, the Company has agreed to call and convene a shareholder meeting to obtain this approval, and Purchaser will vote all Shares it acquires pursuant to the Offer in favor of the adoption of the Merger Agreement.

The Merger Agreement contains customary representations, warranties and covenants of the parties. In addition, under the terms of the Merger Agreement, the Company has agreed not to solicit or otherwise facilitate any alternative Acquisition Proposal (as defined in the Merger Agreement), subject to customary exceptions that permit the Company to respond to an unsolicited bona fide written Acquisition Proposal if the Company’s board of directors determines in good faith that, after consultation with outside counsel and a financial advisor of nationally recognized reputation, such Acquisition Proposal is, or is reasonably likely to lead to, a Superior Proposal (as defined in the Merger Agreement), and that the failure to take such action would reasonably be expected to result in a breach of its fiduciary duties. The Merger Agreement contains certain termination rights for the Company and the Parent, including the Company’s right to terminate the Merger Agreement in order to accept an unsolicited Superior Proposal, subject to giving Parent three business days’ notice of its intention to do so, but only if Parent fails to make a counter-proposal that matches such Superior Proposal and the Company pays Parent a termination fee of $17.5 million. In addition, this termination fee is payable by the Company to Parent under other circumstances specified in the Merger Agreement.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated herein by reference. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Parent or Purchaser. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are qualified by information in a confidential disclosure letter provided by the Company in connection with the signing of the Merger Agreement and contains information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the Merger Agreement. Moreover, certain representations and warranties in the Merger Agreement were used for the purpose of allocating risk among the Company, Parent and Purchaser, rather than establishing matters of fact. Accordingly, the representations and warranties in the Merger Agreement may not constitute the actual state of facts about the Company, Parent or Purchaser.

Tender and Support Agreement

Concurrently with the execution of the Merger Agreement, certain shareholders of the Company and their affiliates, if applicable, who directly or indirectly own 2,748,434 shares of Company Common Stock, representing approximately 10.6% of the Shares outstanding as of September 30, 2010, have entered into a Tender and Support Agreement with Parent and Purchaser (the “Tender and Support Agreement”), which provides, among other things, that such shareholders will tender their Shares in the Offer and vote their Shares in favor of approving the principal terms of the Merger, if applicable. Notwithstanding the foregoing, if so instructed by Parent, each such shareholder has agreed not to tender up to 25% of such shareholder’s Shares or to withdraw previously tendered Shares such that the shareholder remains the owner of up to 25% of such shareholder’s Shares.

The foregoing description of the Tender and Support Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Tender and Support Agreement, which is attached as Exhibit 10.1 hereto and incorporated herein by reference.

First Amendment to Preferred Stock Rights Agreement

On October 2, 2010, the Company and Wells Fargo Bank N.A., as Rights Agent, entered into the First Amendment (the “First Amendment”) to Amended and Restated Rights Agreement dated as of October 17, 2003 (the “Rights Agreement”). The effect of the First Amendment is to permit the execution of the Merger Agreement and the performance and consummation of the transactions contemplated by the Merger Agreement, including the Offer and the Merger, without triggering the separation or exercise of the Company Rights or any adverse event under the Rights Agreement.

The foregoing descriptions of the First Amendment and the Rights Agreement do not purport to be complete and are qualified in their respective entireties by reference to the full text of the First Amendment, which is attached as Exhibit 4.1 hereto and incorporated herein by reference, and the full text of the Rights Agreement, which is attached as Exhibit 4.1 to the Company’s Current Report on Form 8-K filed with the U.S. Securities and Exchange Commission (“SEC”) on October 24, 2003, and incorporated herein by reference.

Item 3.03. Material Modification to Rights of Security Holders.

See disclosure under Item 1.01 “First Amendment to Preferred Stock Rights Agreement” above, which is incorporated by reference into this Item 3.03.
