Item 5. Other Events

     On December 21, 1997, the Board of Directors of Pacific Scientific Company
(the "Company") declared a dividend of one preferred share purchase right (a
"Right") for each outstanding share of common stock, par value $1.00 per share
(the "Common Shares"), of the Company. The dividend is payable on the earlier of
(i) December 21, 1997, or (ii) such date as permitted by the New York Stock
Exchange (the "Record Date") to the stockholders of record on that date. Each
Right entitles the registered holder to purchase from the Company one
one-hundredth of a share of Series B Junior Participating Preferred Stock, par
value $1.00 per share (the "Preferred Shares"), of the Company at a price of $75
per one one-hundredth of a Preferred Share (the "Purchase Price"), subject to
adjustment. The description and terms of the Rights are set forth in a Rights
Agreement (the "Rights Agreement") between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent (the "Rights Agent").

     Until the earlier to occur of (i) 10 days following a public announcement
that a person or group of affiliated or associated persons (an "Acquiring
Person") have acquired beneficial ownership of 10% or more of the outstanding
Common Shares or (ii) 10 business days (or such later date as may be determined
by action of the Board of Directors prior to such time as any person or group of
affiliated persons becomes an Acquiring Person) following the commencement of,
or announcement of an intention to make, a tender offer or exchange offer the
consummation of which would result in the beneficial ownership by a person or
group of 10% or more of the outstanding Common Shares (the earlier of such dates
being called the "Distribution Date"), the Rights will be evidenced, with
respect to any of the Common Share certificates outstanding as of the Record
Date, by such Common Share certificate with a copy of a Summary of Rights
attached thereto. An unsolicited tender offer is currently pending with respect
to the Common Shares and the Company has filed a Solicitation/Recommendation
Statement on Schedule 14D-9 (the "Schedule 14D-9") with respect thereto. A copy
of the Schedule 14D-9 is filed as an exhibit hereto and is hereby incorporated
herein by reference. As noted in the Schedule 14D-9, in connection with its
adoption of the Rights Agreement, the Board of Directors of the Company
resolved, in accordance with the provisions of the Rights Agreement, that the
Distribution Date will, for all purposes under the Rights Agreement, be deferred
until the earlier of: (i) 10 days after the first date of public announcement by
the Company or an Acquiring Person that an Acquiring Person has become such; or
(ii) such date as may be subsequently determined by the Board.

     The Rights Agreement provides that, until the Distribution Date (or earlier
redemption or expiration of the Rights), the Rights will be transferred with and
only with the Common Shares. Until the Distribution Date (or earlier redemption
or expiration of the Rights), new Common Share certificates issued after the
Record Date upon transfer or new issuance of Common Shares will contain a
notation incorporating the Rights Agreement by reference. Until the Distribution
Date (or earlier redemption or expiration of the Rights), the surrender for
transfer of any certificates for Common Shares outstanding as of the Record
Date, even without such notation or a copy of this Summary of Rights being
attached thereto, will also constitute the transfer of the Rights associated
with the Common Shares represented by such certificate. As soon as practicable
following the Distribution Date, separate certificates evidencing the Rights
("Right Certificates") will be mailed to holders of record of the Common Shares

as of the close of business on the Distribution Date and such separate Right
Certificates alone will evidence the Rights.

     The Rights are not exercisable until the Distribution Date. The Rights will
expire on December 21, 2007 (the "Final Expiration Date"), unless the Final
Expiration Date is extended or unless the Rights are earlier redeemed or
exchanged by the Company, in each case, as described below.

                                  Page 2 of 6



     The Purchase Price payable, and the number of Preferred Shares or other
securities or property issuable, upon exercise of the Rights are subject to
adjustment from time to time to prevent dilution (i) in the event of a stock
dividend on, or a subdivision, combination or reclassification of, the Preferred
Shares, (ii) upon the grant to holders of the Preferred Shares of certain rights
or warrants to subscribe for or purchase Preferred Shares at a price, or
securities convertible into Preferred Shares with a conversion price, less than
the then-current market price of the Preferred Shares or (iii) upon the
distribution to holders of the Preferred Shares of evidences of indebtedness or
assets (excluding regular periodic cash dividends paid out of earnings or
retained earnings or dividends payable in Preferred Shares) or of subscription
rights or warrants (other than those referred to above).

     The number of outstanding Rights and the number of one one-hundredths of a
Preferred Share issuable upon exercise of each Right are also subject to
adjustment in the event of a stock split of the Common Shares or a stock
dividend on the Common Shares payable in Common Shares or subdivisions,
consolidations or combinations of the Common Shares occurring, in any such case,
prior to the Distribution Date.

     Preferred Shares purchasable upon exercise of the Rights will not be
redeemable. Each Preferred Share will be entitled to a minimum preferential
quarterly dividend payment of $1 per share but will be entitled to an aggregate
dividend of 100 times the dividend declared per Common Share. In the event of
liquidation, the holders of the Preferred Shares will be entitled to a minimum
preferential liquidation payment of $100 per share but will be entitled to an
aggregate payment of 100 times the payment made per Common Share. Each Preferred
Share will have 100 votes, voting together with the Common Shares. Finally, in
the event of any merger, consolidation or other transaction in which Common
Shares are exchanged, each Preferred Share will be entitled to receive 100 times
the amount received per Common Share. These rights are protected by customary
antidilution provisions.

     Because of the nature of the Preferred Shares' dividend, liquidation and
voting rights, the value of the one one-hundredth interest in a Preferred Share
purchasable upon exercise of each Right should approximate the value of one
Common Share.

     In the event that the Company is acquired in a merger or other business
combination transaction or 50% or more of its consolidated assets or earning
power are sold after a person or group has become an Acquiring Person, proper
provision will be made so that each holder of a Right will thereafter have the
right to receive, upon the exercise thereof at the then current exercise price
of the Right, that number of shares of common stock of the acquiring company
which at the time of such transaction will have a market value of two times the
exercise price of the Right. In the event that any person or group of affiliated
or associated persons becomes an Acquiring Person, proper provision shall be
made so that each holder of a Right, other than Rights beneficially owned by the
Acquiring Person (which will thereafter be void), will thereafter have the right
to receive upon exercise that number of Common Shares having a market value of
two times the exercise price of the Right.

     At any time after any person or group becomes an Acquiring Person and prior
to the acquisition by such person or group of 50% or more of the outstanding
Common Shares, the Board of Directors of the Company may exchange the Rights
(other than Rights owned by such

                                  Page 3 of 6


person or group which will have become void), in whole or in part, at an
exchange ratio of one Common Share, or one one-hundredth of a Preferred Share
(or of a share of a class or series of the Company's preferred stock having
equivalent rights, preferences and privileges), per Right (subject to
adjustment).

     With certain exceptions, no adjustment in the Purchase Price will be
required until cumulative adjustments require an adjustment of at least 1% in
such Purchase Price. No fractional Preferred Shares will be issued (other than
fractions which are integral multiples of one one-hundredth of a Preferred
Share, which may, at the election of the Company, be evidenced by depositary
receipts) and in lieu thereof, an adjustment in cash will be made based on the
market price of the Preferred Shares on the last trading day prior to the date
of exercise.

     At any time prior to the acquisition by a person or group of affiliated or
associated persons of beneficial ownership of 10% or more of the outstanding
Common Shares, the Board of Directors of the Company may redeem the Rights in
whole, but not in part, at a price of $.01 per Right (the "Redemption Price").
The redemption of the Rights may be made effective at such time on such basis
with such conditions as the Board of Directors in its sole discretion may
establish. Immediately upon any redemption of the Rights, the right to exercise
the Rights will terminate and the only right of the holders of Rights will be to
receive the Redemption Price.

     Until a Right is exercised, the holder thereof, as such, will have no
rights as a stockholder of the Company, including, without limitation, the right
to vote or to receive dividends.
