MICROSEMI ANNOUNCES REDEMPTION OF 5 7/8 PERCENT CONVERTIBLE SUBORDINATED
DEBENTURES


     SANTA ANA, Calif.--January 26, 1998--Microsemi Corp. (Nasdaq: MSCC) Monday
announced that it will redeem on Feb. 12, 1998, all of its outstanding 5-7/8
percent convertible subordinated debentures due 2012.

     The debentures are redeemable at $1,000 principal amount, plus accrued
interest to Feb. 12, 1998, of $26.27 per $1,000 principal amount, for a total
redemption price of $1,026.27.

     The debentures are convertible into the company's common stock at a
conversion price of $13.55 per share, or 73.8 shares per $1,000 principal
amount. Debentures may be converted at any time prior to 5:00 p.m. PST, on Feb.
12, 1998, in accordance with the terms of the indenture.

     Debentures may be presented for payment of the redemption price at the Bank
of New York, Bond Redemption Unit, Lobby Level, 101 Barclay St., New York, N.Y.
10286 for redemption, and for conversion at the Bank of New York, Reorganization
Unit, Lobby Level, 101 Barclay St., New York, N.Y.  10286.

     On Feb. 12, 1998, the redemption price and accrued interest on each
outstanding debenture will become due and payable, and interest thereon will
cease to accrue. If the debenture holder elects to convert, no payment of
interest and no adjustment in respect of interest will be made, and no
fractional shares of common stock will be issued; however, if a conversion
results in a fraction of a share, the debenture holders will receive a cash
payment in lieu thereof.

     The company has previously received notices from holders of $22,953,000 in
face value of debentures, indicating their intention to convert their debentures
into common stock. This represents 69 percent of the outstanding debentures.

     The company is sending to each debenture holder of record a notice and
transmittal letter outlining the procedure for redemption and conversion.
