Microsemi Announces Completion of its Offer to Amend and Accelerate Employee Stock Options


IRVINE, Calif., Sept. 22, 2005 (PRIMEZONE) -- Microsemi Corporation (Nasdaq:MSCC) announced that it has completed its Offer to Amend and Accelerate Employee Stock Options, which expired on Tuesday, September 20, 2005 at 5:00 P.M. U.S. Pacific Daylight Time. Pursuant to this offer, the Company accelerated the vesting, at the election of the option holders, of some of the outstanding employee stock options under its 1987 Stock Plan, as amended. As a result, options held by employees to purchase approximately 5,147,910 shares of common stock became fully vested and exercisable on September 21, 2005. The acceleration included options held by executive officers to purchase approximately 1,324,000 shares. A total of approximately 5,163,975 options had been eligible for the offer.

Microsemi believes that completion of the offer will benefit all Microsemi stockholders by substantially reducing future compensation expense that the Company would otherwise recognize in its income statements with respect to the outstanding options as they vest. The completion of the offer coincided with Microsemi's planned October 3, 2005 adoption of FASB Statement No. 123R, "Share-Based Payment," effective for its fiscal year 2006. Therefore, the Company wanted to accelerate vesting of options into its fiscal year 2005 before the new accounting rule takes effect.

Under the terms of the offer, the shares of common stock to be issued upon exercise of the accelerated options, once purchased, shall belong to the option holder, and shall be registered in the name of the option holder, free of forfeiture provisions. Upon exercise of these options, holders may sell a portion of these shares pursuant to a public market sale to the extent necessary to pay the option holders' out-of-pocket costs for the option exercise price, taxes and commissions. The remaining shares are non-transferable, except pursuant to the laws of descent and distribution, with sale restrictions lapsing under the original, non-accelerated, vesting period.

THIS IS NOT AN OFFER OF ANY SECURITY FOR SALE.
