Pursuant to Section 151 of the General Corporation Law
of the State of Delaware
We, James Peterson and David R. Sonksen, the Chief Executive Officer and
President and the Executive Vice President, Chief Financial Officer and
Secretary, respectively, of Microsemi Corporation, a corporation organized and
existing under the General Corporation Law of the State of Delaware, in
accordance with the provisions of Section 103 thereof, DO HEREBY CERTIFY:
That pursuant to the authority conferred upon the Board of Directors by the
Restated Certificate of Incorporation of the said Corporation, the said Board of
Directors on November 28, 2000 adopted the following resolution creating a
series of 100,000 shares of Preferred Stock designated as Series A Junior
Participating Preferred Stock:
RESOLVED, that pursuant to the authority vested in the Board of
Directors of the corporation by the Certificate of Incorporation (as
heretofore amended called the "Certificate of Incorporation") the Board of
Directors does hereby provide for the issue of a series of Preferred Stock,
par value $1.00 per share, of the Corporation, to be designated "Series A
Junior Participating Preferred Stock," initially consisting of 100,000
shares and to the extent that the designations, powers, preferences and
relative and other special rights and the qualifications, limitations and
restrictions of the Series A Junior Participating Preferred Stock are not
stated and expressed in the Second Restated Certificate of Incorporation,
does hereby fix and herein state and express such designations, powers,
preferences and relative and other special rights and the qualifications,
limitations and restrictions thereof, as follows (all terms used herein
which are defined in the Certificate of Incorporation shall be deemed to
have the meanings provided therein):
Section 1. Designation and Amount. The shares of such series shall
----------------------

$1.00 per share, and the number of shares constituting such series shall be
100,000.

Section 2. Dividends and Distributions.
---------------------------
(A) Subject to the prior and superior right of the holders of any
shares of any series of Preferred Stock ranking prior and superior to the
shares of Series A Junior Participating Preferred Stock with respect to
dividends, the holders of shares of Series A Junior Participating Preferred
Stock shall be entitled to receive when, as and if declared by the Board of
Directors out of funds legally available for the purpose, quarterly
dividends payable in cash on the last day of September, December, March and
June in each year (each such date being referred to herein as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment
Date after the first issuance of a share or fraction of a share of Series A
Junior Participating Preferred Stock, in an amount per share (rounded to
the nearest cent) equal to, subject to the provision for adjustment
hereinafter set forth, 10,000 times the aggregate per share amount of all
cash dividends, and 10,000 times the aggregate per share amount (payable in
kind) of all non-cash dividends or other distributions other than a
dividend payable in shares of Common Stock or a subdivision of the
outstanding shares of Common Stock (by reclassification or otherwise),
declared on the Common Stock of the Corporation (the "Common Stock") since
the immediately preceding Quarterly Dividend Payment Date, or, with respect
to the first Quarterly Dividend Payment Date, since the first issuance of
any share or fraction of a share of Series A Junior Participating Preferred
Stock. In the event the Corporation shall at any time after the close of
business on December 22, 2000 (the "Rights Declaration Date") (i) declare
any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding
Common Stock into a smaller number of shares, then in each such case, the
amount to which holders of shares of Series A Junior Participating
Preferred Stock were entitled immediately prior to such event under the
preceding sentence shall be adjusted by multiplying such amount by a
fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately
prior to such event.
(B) The Corporation shall declare a dividend or distribution on
the Series A Junior Participating Preferred Stock as provided in paragraph
(A) above immediately after it declares a dividend payable in shares of
Common Stock.
(C) Dividends shall begin to accrue and be cumulative on
outstanding shares of Series A Junior Participating Preferred Stock from
the Quarterly Dividend Payment Date next preceding the date of issue of
such shares of Series A Junior Participating Preferred Stock, unless the
date of issue of such shares is prior to the record date for the first
Quarterly Dividend Payment Date, in which case dividends on such
2
<PAGE>
shares shall begin to accrue from the date of issue of such shares, or
unless the date of issue is a Quarterly Dividend Payment Date or is a date
after the record date for the determination of holders of shares of Series
A Participating Preferred Stock entitled to receive a quarterly dividend
and before such Quarterly Dividend Payment Date, in either of which events
such dividends shall begin to accrue and be cumulative from such Quarterly
Dividend Payment Date. Accrued but unpaid dividends shall not bear
interest. Dividends paid on the shares of Series A Junior Participating
Preferred Stock in an amount less than the total amount of such dividends
at the time accrued and payable on such shares shall be allocated pro rata
on a share-by-share basis among all such shares at the time outstanding.
The Board of Directors may fix a record date for the determination of
holders of shares of Series A Junior Participating Preferred Stock entitled
to receive payment of a dividend or distribution declared thereon, which
record date shall be no more than thirty (30) days prior to the date fixed
for the payment thereof.
Section 3. Voting Rights. The holders of shares of Series A Junior
-------------
Participating Preferred Stock shall have the following voting rights:
(A) Subject to the provision for adjustment hereinafter set
forth, each share of Series A Junior Participating Preferred Stock shall
entitle the holder thereof to 1,000 votes on all matters submitted to a
vote of the stockholders of the Corporation. In the event the Corporation
shall at any time after the Rights Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide
the outstanding Common Stock, or (iii) combine the outstanding Common Stock
into a smaller number of shares, then in each such case the number of votes
per share to which holders of shares of Series A Junior Participating
Preferred Stock were entitled immediately prior to such event shall be
adjusted by multiplying such number by a fraction, the numerator of which
is the number of shares of Common Stock outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.
(B) Except as otherwise provided herein or by law, the holders of
shares of Series A Junior Participating Preferred Stock and the holders of
shares of Common Stock shall vote together as one class on all matters
submitted to a vote of stockholders of the Corporation.
(C) Except as required by law, holders of Series A Junior
Participating Preferred Stock shall have no special voting rights and their
consent shall not be required (except to the extent they are entitled to
vote with holders of Common stock as set forth herein) for taking any
corporate action.

Section 4. Certain Restrictions.
--------------------
(A) The Corporation shall not declare any dividend on, make any
distribution on, or redeem or purchase or otherwise acquire for
consideration any shares of Common Stock after the first issuance of a
share or fraction of a share of Series A Junior Participating Preferred
Stock unless concurrently therewith it shall declare a dividend on the
Series A Junior Participating Preferred Stock as required by Section 2
hereof.
(B) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Junior Participating Preferred Stock
as provided in Section 2 are in arrears, thereafter and until all accrued
and unpaid dividends and distributions, whether or not declared, on shares
of Series A Junior Participating Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:
(i) declare or pay dividends on, make any other
distributions on, or redeem or purchase or otherwise acquire for
consideration any shares of stock ranking junior (either as to dividends or
upon liquidation, dissolution or winding up) to the Series A Junior
Participating Preferred Stock;
(ii) declare or pay dividends on, make any other
distributions on any shares of stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with Series A
Junior Participating Preferred Stock, except dividends paid ratably on the
Series A Junior Participating Preferred stock and all such parity stock on
which dividends are payable or in arrears in proportion to the total
amounts to which the holders of all such shares are then entitled;
(iii) redeem or purchase or otherwise acquire for
consideration shares of any stock ranking on a parity (either as to
dividends or upon liquidation, dissolution or winding up) with the Series A
Junior Participating Preferred Stock, provided that the Corporation may at
any time redeem purchase or otherwise acquire shares of any such parity
stock in exchange for shares of any stock of the Corporation ranking junior
(either as to dividends or upon dissolution, liquidation or winding up) to
the Series A Junior Participating Preferred Stock; or
(iv) purchase or otherwise acquire for consideration any
shares of Series A Junior Participating Preferred Stock, or any shares of
stock ranking on a parity with the Series A Junior Participating Preferred
Stock, except in accordance with a purchase offer made in writing or by
publication (as determined by the Board of Directors) to all holders of
such shares upon such terms as the Board of
4
<PAGE>
Directors, after consideration of the respective annual dividend rates and
other relative rights and preferences of the respective series and classes,
shall determine in good faith will result in fair and equitable treatment
among the respective series or classes.
(C) The Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares
of stock of the Corporation unless the Corporation could, under paragraph
(A) of this Section 4, purchase or otherwise acquire such shares at such
time and in such manner.
Section 5. Reacquired Shares. Any shares of Series A Junior
-----------------
Participating Preferred Stock purchased or otherwise acquired by the
Corporation in any manner whatsoever shall be retired and cancelled
promptly after the acquisition thereof. All such shares shall upon their
cancellation become authorized but unissued shares of Preferred Stock and
may be reissued as part of a new series of Preferred Stock to be created by
resolution or resolutions of the Board of Directors, subject to the
conditions and restrictions on issuance set forth herein.
Section 6. Liquidation, Dissolution or Winding Up.
--------------------------------------
(A) Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the Corporation, no distribution shall be made to the holders
of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Junior
Participating Preferred Stock unless, prior thereto, the holders of shares
of Series A Junior Participating Preferred Stock shall have received an
amount equal to accrued and unpaid dividends and distributions thereon,
whether or not declared, to the date of such payment, plus an amount equal
to the greater of (1) $400,000 per share, provided that in the event the
Corporation does not have sufficient assets, after payment of its
liabilities and distribution to holders of Preferred Stock ranking prior to
the Series A Participating Preferred Stock, available to permit payment in
full of the $400,000 per share amount, the amount required to be paid under
this Section 6(A)(1) shall, subject to Section 6(B) hereof, equal the value
of the amount of available assets divided by the number of outstanding
shares of Series A Participating Preferred Stock or (2) subject to the
provisions for adjustment hereinafter set forth, 10,000 times the aggregate
per share amount to be distributed to the holders of Common Stock (the
greater of (1) or (2), the "Series A Liquidation Preference"). In the
event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock,
(ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such
case the amount to which holders of shares of Series A Junior Participating
Preferred Stock were entitled immediately prior to
5
<PAGE>
such event under clause (2) of the preceding sentence shall be adjusted by
multiplying such amount by a fraction the numerator of which is the number
of shares of Common Stock that were outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock
that were outstanding immediately prior to such event.
(B) In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference
and the liquidation preferences of all other series of Preferred Stock, if
any, which rank on a parity with the Series A Junior Participant Preferred
Stock, then such remaining assets shall be distributed ratably to the
holders of such parity shares in proportion to their respective liquidation
preferences.
Section 7. Consolidation, Merger, etc. In case the Corporation shall
--------------------------
enter into any consolidation, merger, combination or other transaction in
which the shares of Common Stock are exchanged for or changed into other
stock or securities, cash and/or any other property, then in any such case
the shares of Series A Participating Preferred Stock shall at the same time
be similarly exchanged or changed in amount per share (subject to the
provision for adjustment hereinafter set forth) equal to 10,000 times the
aggregate amount of stock, securities, cash and/or any other property
(payable in kind), as the case may be, into which or for which each share
of Common Stock is changed or exchanged. In the event the Corporation
shall at any time after the Rights Declaration Date (i) declare any
dividend on Common Stock payable in shares of Common Stock, (ii) subdivide
the outstanding Common Stock, or (iii) combine the outstanding Common Stock
into a smaller number of shares, then in each such case the amount set
forth in the preceding sentence with respect to the exchange or change of
shares of Series A Junior Participating Preferred Stock shall be adjusted
by multiplying such amount by a fraction the numerator of which is the
number of shares of Common Stock outstanding immediately after such event
and the denominator of which is the number of shares of Common Stock that
were outstanding immediately prior to such event.
Section 8. No Redemption. The shares of Series A Junior
-------------
Participating Preferred Stock shall not be redeemable.
Section 9. Ranking. The Series A Junior Participating Preferred
-------
Stock shall rank junior to all other series of the Corporation's Preferred
Stock as to the payment of dividends and the distribution of assets, unless
the terms of any such series shall provide otherwise.
Section 10. Amendment. The Certificate of Incorporation, as amended,
---------
of the Corporation shall not be further amended in any manner which would
materially alter or change the powers, preference or special
6
<PAGE>
rights of the Series A Junior Participating Preferred Stock so as to affect
them adversely without the affirmative vote of the holders of a majority or
more of the outstanding shares of Series A Junior Participating Preferred
Stock, voting separately as a class.
Section 11. Fractional Shares. Series A Junior Participating
-----------------
Preferred Stock may be issued in fractions that are integral multiples of
one one-thousandth of one share, which shall entitle the holder, in
proportion to such holder's fractional shares, to exercise voting rights,
receive dividends, participate in distributions and to have the benefit of
all other rights of holders of Series A Junior Participating Preferred
Stock.
IN WITNESS WHEREOF, we have executed and subscribed this Certificate of
Designation and do affirm the foregoing as true under the penalties of perjury
this 21st day of December, 2000.
