           Microsemi Announces Further Information Upon Stock Split


Irvine, CA - (BusinessWire) August 29, 2001 - Microsemi Corporation (Nasdaq:
MSCC), has today before the opening of trading released a compilation of
information and historical background, including substantially all of the text
of a letter addressed to its stockholders of record or any beneficial owners who
may have any indirect interest in Microsemi Common Stock, concerning the
effectiveness of the 2 for 1 stock split.

As you know, Microsemi Corporation has enjoyed many successes, including stock
appreciation, in 2000/2001.

To allow shareholders to better share in this success, the Board of Directors
has declared a 2-for-1 stock split effected by a stock dividend.  The Board of
Directors believes that this should ultimately have a positive impact on the
attractiveness of the Common Stock to institutional investors and advisors.

Because this stock split is effected by way of a stock dividend, DO NOT DESTROY
OLD CERTIFICATES and DO NOT SEND THEM IN FOR EXCHANGE.  The stock dividend is
payable on August 28, 2001 to all stockholders of record as of August 14, 2001
and their assigns who hold due bills written only on or before August 28, 2001.
The address of the Registrant's transfer agent is Mellon Investor Services, 85
Challenger Road, Ridgefield Park, New Jersey 07660 (Toll Free: 800-522-6645).

Thank you for your continued support and confidence in the company.  The company
is committed to working hard on your behalf and look forward to your continued
support.

History

The holders of a majority of the outstanding common stock had given, as of July
31, 2001, their written consent to an increase from 20,000,000 to 100,000,000 in
the authorized Common Stock of the Registrant, and the Board of Directors
announced on July 31, 2001 that such written consent had been obtained.  The
Board of Directors had authorized that such dividend be declared, a dividend
payable in shares of


common stock, if and when the stockholders shall have consented in writing to
such increase in the authorized Common Stock. As declared and announced on July
31, 2001, the Board of Directors approved a two-for-one stock split of the
Registrant's issued and outstanding Common Stock effected by way of a common
stock dividend payable to the holders of its common stock as of the close of
business on August 14, 2001 (the "Record Date"), at which time there were
14,118,738 shares of Common Stock issued and outstanding or held in treasury.
The additional stock certificates issuable as a result of the dividend will be
mailed on or about August 28, 2001. The opening of trading today, on August 29,
2001 will be the deferred "ex-dividend" date at which time this 2-for-1 stock
split will be reflected in the quoted price per share of Common Stock. Those due
bills will be redeemed by the company's transfer agent beginning on August 31,
2001 in exchange for certificates representing an additional 14,118,738 shares
of Common Stock distributed to effect our 2-for-1 stock split.

Since the Record Date, under the auspices of the Nasdaq Stock Market and with
our Board of Directors' approval, all Common Stock that has been transferred has
included the full value of the outstanding shares plus a "due bill" representing
the right to receive the equal number of shares in the stock dividend
distribution.  As a result of all such assignments by means these instruments
known as the "due bill" to the purchasers of Common Stock, the dividend
distribution will become due to the holders of the due bills.  All sellers of
Common Stock before August 29, 2001 who held the Stock on the Record Date
thereby should receive full value, including the value of the dividend
distribution, and give full value, including the due bills.

Holders of record at the closing on August 14, 2001 and the holders of due bills
written on all transfers up to and including August 28, 2001, receive a new
stock certificate (the "new" certificate), representing the additional shares of
Common Stock to which you would be entitled as a record or beneficial owner, as
the case may be, as a result of the stock split.  The certificates that any
record owner has held (the "old" certificates) remain valid and continue to
represent the same number of shares.  One's total stock holdings in the Company
would be now the total of the "old" and the "new" certificates taken together.
While the number of shares of Common Stock one may own are now effectively
doubled as a result of the stock split, one's proportionate equity interest in
the Company and its aggregate inherent value is unchanged.

The Company is advised by its counsel that under the provisions of the Internal
Revenue Code, the stock split will not result in any gain or loss for federal
income tax purposes to holders of the Company's Common Stock.  The tax basis of
each share of the Company's stock held immediately after the stock split will be
equal to 50% of the tax basis of each share held immediately prior to the stock
split.  The Company is further advised that the shares of Common Stock issued
upon the dividend distribution are validly issued, fully paid and non-
assessable.
