TO THE HOLDERS OF COMMON STOCK OF
PACIFIC SCIENTIFIC COMPANY:
 
                                  INTRODUCTION
 
     ACC Acquisition Corp., a California corporation (the 'Purchaser') and an
indirect wholly owned subsidiary of Danaher Corporation, a Delaware corporation
('Parent'), hereby offers to purchase all outstanding shares of common stock,
par value $1.00 per share (the 'Common Shares'), of Pacific Scientific Company,
a California corporation (the 'Company'), together with the associated Preferred
Share Purchase Rights (the 'Rights' and, together with the Common Shares, the
'Shares') issued pursuant to the Rights Agreement, dated as of December 21,
1997, as amended as of January 31, 1998, between the Company and ChaseMellon
Shareholder Services, L.L.C., as Rights Agent (as amended, the 'Rights
Agreement'), at $30.25 per Share (the 'Offer Price'), net to the seller in cash,
without interest, upon the terms and subject to the conditions set forth in this
Offer to Purchase and in the related Letter of Transmittal (which, as amended or
supplemented from time to time, together constitute the 'Offer').
 
     Tendering shareholders will not be obligated to pay brokerage fees or
commissions or, except as set forth in Instruction 6 of the Letter of
Transmittal, stock transfer taxes on the purchase of Shares by the Purchaser
pursuant to the Offer. The Purchaser will pay all fees and expenses of Furman
Selz LLC, which is acting as the Dealer Manager (the 'Dealer Manager'), First
Chicago Trust Company of New York, which is acting as the Depositary (the
'Depositary'), and D.F. King & Co., Inc., which is acting as the Information
Agent (the 'Information Agent'), incurred in connection with the Offer. See
Section 16.
 
     The Offer is conditioned upon, among other things, there being validly
tendered and not withdrawn prior to the expiration of the Offer that number of
Shares which represents at least ninety percent of the Shares outstanding on the
date of purchase (the 'Minimum Condition'). See Section 14.
 
     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of January 31, 1998 (the 'Merger Agreement'), by and among the Company, DH
Holdings Corp., a Delaware corporation and a direct wholly owned subsidiary of
Parent ('Holdings'), and the Purchaser. The Merger Agreement provides that,
among other things, following the consummation of the Offer and the satisfaction
or waiver of the other conditions set forth in the Merger Agreement, the
Purchaser will be merged with and into the Company (the 'Merger'), with the
Company continuing as the surviving corporation (the 'Surviving Corporation').
At the effective time of the Merger (the 'Effective Time'), each outstanding
Share (other than Shares held in the treasury of the Company or by any wholly
owned subsidiary of the Company and Shares owned by Holdings, the Purchaser or
any other wholly owned subsidiary of Holdings or the Purchaser or held by
shareholders, if any, who are entitled to and who properly exercise dissenters'
rights under California law) will be converted into the right to receive an
amount in cash equal to the Offer Price, without interest. See Section 12.
 
     THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE OFFER AND THE
MERGER, HAS DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR TO

AND IN THE BEST INTERESTS OF THE SHAREHOLDERS OF THE COMPANY AND RECOMMENDS THAT
SHAREHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
     BancAmerica Robertson Stephens, the Company's financial advisor, has
delivered to the Board of Directors of the Company its written opinion to the
effect that, as of the date of such opinion, and based on the assumptions made,
matters considered and limits of review set forth therein, the consideration to
be received by the holders of the Shares (other than Holdings, the Purchaser,
any affiliates of Holdings or the Purchaser and holders of Shares, if any, who
are entitled to and who properly exercise dissenters' rights under California
law) in the Offer and the Merger is fair to the holders of Shares, from a
financial point of view. Such opinion is set forth in full as an exhibit to the
Company's Solicitation/Recommendation Statement on Schedule 14D-9 (the 'Schedule
14D-9'), which is being mailed to shareholders of the Company herewith.
 
     Pursuant to the Merger Agreement, promptly upon the purchase by the
Purchaser of Shares representing at least such number of Shares as shall satisfy
the Minimum Condition, and from time to time thereafter, Holdings shall be
entitled to designate up to such number of directors, rounded up to the next
whole number, on the Board of Directors of the Company as is equal to the number
of directors which is the product of (a) the total number of directors on the
Board of Directors of the Company (giving effect to the directors elected
pursuant to this sentence) multiplied by (b) the percentage that the aggregate
number of Shares beneficially owned by Holdings or its affiliates bears to the
total number of Shares then outstanding on a fully diluted basis.
Notwithstanding the foregoing, the Company, Holdings and the Purchaser have
agreed that, until the Effective Time, the Board of

<PAGE>

Directors of the Company shall have at least two directors (the 'Independent
Directors') who are not officers, directors or designees of the Purchaser or any
of its affiliates; provided, however, that, in such event, if the number of
Independent Directors shall be reduced below two, the remaining Independent
Director shall be entitled to designate a person to fill such vacancy who shall
not be an officer, director or designee of the Purchaser or any of its
affiliates and who shall be deemed to be an Independent Director for purposes of
the Merger Agreement. In the Merger Agreement, the Company has agreed, upon
request of Holdings, to take all actions necessary to cause Holdings' designees
to be so elected, including mailing to its shareholders the Information
Statement containing the information required by Section 14(f) of the Securities
Exchange Act of 1934, as amended (the 'Exchange Act'), and Rule 14f-1
promulgated thereunder, and, if necessary, seeking the resignation of one or
more existing directors.
 
     Following the satisfaction or waiver of the conditions to the Offer, the
Purchaser will accept for payment, in accordance with the terms of the Offer,
all Shares validly tendered pursuant to the Offer as soon as practicable after
the Expiration Date (as hereinafter defined). The Merger Agreement provides that
the Purchaser may under certain circumstances, from time to time, extend the
expiration date of the Offer beyond the time it would otherwise be required to
accept validly tendered Shares for payment. The Offer will not remain open
following the time Shares are accepted for payment.
 

     As indicated above, the Merger Agreement contemplates a two-step
transaction in which, following consummation of the Offer, the Merger occurs.
Under the General Corporation Law of the State of California (the 'GCL'), if the
Purchaser acquires, pursuant to the Offer or otherwise, at least 90% of the then
outstanding Shares, the Purchaser will be able to approve and adopt the Merger
Agreement and the transactions contemplated thereby, including the Merger,
without a vote of the Company's shareholders. In such event, Holdings, the
Purchaser and the Company have agreed to take all necessary and appropriate
action to cause the Merger to become effective as soon as practicable after such
acquisition, without a meeting of the Company's shareholders, in accordance with
the GCL. However, under the GCL, the Merger may not be accomplished for cash
paid to the remaining Company shareholders if the Purchaser, Holdings or Parent
owns directly or indirectly more than 50% but less than 90% of the then
outstanding Shares unless either all of the remaining shareholders of the
Company consent to the Merger or the Commissioner of Corporations of the State
of California approves, after a hearing, the terms and conditions of the Merger
and the fairness thereof. Accordingly, Parent and the Company intend to proceed
simultaneously with an alternative to this two-step transaction in which the
Company pursues a one-step cash merger at the Offer Price. This one-step
transaction would require the affirmative vote of a majority of the Company's
outstanding voting stock. In the event the Minimum Condition is not fulfilled,
the Merger Agreement contemplates that the Offer will be terminated and Parent
and the Company will seek to implement the one-step cash merger transaction. In
furtherance of the foregoing, if on the scheduled Expiration Date (or any
extension thereof) all of the conditions to the Offer other than the Minimum
Condition are satisfied but less than 90% of the outstanding Shares have been
validly tendered and not withdrawn in the Offer, the Purchaser has agreed to
extend the Offer for one additional business day (or such longer time as may be
agreed to by the Purchaser and the Company), and to effect additional extensions
as necessary until the earlier of (i) the close of business on the business day
immediately prior to the Special Meeting (as defined herein) or (ii) such time
as the Minimum Condition has been satisfied. See Section 12.
 
     Pursuant to the Merger Agreement, the Company has agreed to duly call, give
notice of, convene and hold a special meeting of its shareholders (the 'Special
Meeting') as soon as practicable following the date of the Merger Agreement for
the purpose of considering and taking action upon the Merger and the adoption of
the Merger Agreement pursuant to a one-step cash merger. The Merger Agreement
provides that the Company will prepare and file with the Securities and Exchange
Commission (the 'SEC') a preliminary proxy statement relating to the Special
Meeting and cause a definitive proxy statement relating to the Special Meeting
to be mailed to its shareholders for the purpose of obtaining the necessary
approvals of the Merger and the Merger Agreement from its shareholders. The
affirmative vote of a majority of the outstanding Shares would be required to
approve the Merger and the Merger Agreement at the Special Meeting. However, if
the Minimum Condition and the other conditions to the Offer are satisfied prior
to the Special Meeting, the Purchaser will acquire at least 90% of the Shares
outstanding and will be able to approve and adopt the Merger and the Merger
Agreement without a vote of the Company's shareholders and the Special Meeting
will be cancelled.
 
                                       2

     According to the Company, as of January 30, 1998 there were 12,481,306
Shares issued and outstanding, no Shares held by the Company in its treasury and
1,153,264 Shares reserved for issuance pursuant to the Company's outstanding
employee stock options ('Options') granted pursuant to stock option programs or
arrangements of the Company (the 'Stock Plans'). Based upon the foregoing
information, the Minimum Condition would be satisfied if 11,233,176 Shares were
validly tendered (assuming no Shares are issued pursuant to the exercise of
Options after January 30, 1998) or if 12,271,113 Shares were validly tendered
(assuming the exercise of all Options prior to the Expiration Date).
 
     The Company has distributed one Right for each outstanding Common Share
pursuant to the Rights Agreement. The Company has represented in the Merger
Agreement that it has taken all action which may be necessary under the Rights
Agreement and has, on January 31, 1998, amended the Rights Agreement, so that
the execution of the Merger Agreement, the making of the Offer, the acquisition
of Shares pursuant to the Offer and the consummation of the Merger will not
cause (i) any Rights issued pursuant to the Rights Agreement to become
exercisable or to separate from the share certificates to which they are
attached, (ii) Holdings, the Purchaser, or any of their affiliates to become an
Acquiring Person (as defined in the Rights Agreement), or (iii) trigger other
provisions of the Rights Agreement, including giving rise to a Distribution Date
(as defined in the Rights Agreement).
 
     THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ CAREFULLY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.
 
1. TERMS OF THE OFFER
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any extension or
amendment), the Purchaser will accept for payment and pay for all Shares which
are validly tendered prior to the Expiration Date and not withdrawn in
accordance with Section 4. The term 'Expiration Date' means 12:00 Midnight, New
York City time, on Friday, March 6, 1998, unless and until the Purchaser, in its
sole discretion (but subject to the terms of the Merger Agreement), shall have
extended the period of time during which the Offer is open, in which event the
term 'Expiration Date' shall mean the latest time and date at which the Offer,
as so extended by the Purchaser, shall expire.
 
     The Offer is conditioned upon, among other things, satisfaction of the
Minimum Condition and the expiration or termination of all waiting periods
imposed by the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended
(the 'HSR Act'). See Section 14, which sets forth in full the conditions to the
Offer. If any condition is not satisfied or any or all of the other events set
forth in Section 14 shall have occurred or shall be determined by the Purchaser
to have occurred prior to the Expiration Date, the Purchaser reserves the right
(but shall not be obligated) to (i) decline to purchase any of the Shares
tendered in the Offer and terminate the Offer and return all tendered Shares to
the tendering shareholders, (ii) waive any or all conditions to the Offer, to
the extent permitted by applicable law and the provisions of the Merger
Agreement, and, subject to complying with applicable rules and regulations of
the SEC, purchase all Shares validly tendered or (iii) extend the Offer and,

subject to the right of shareholders to withdraw Shares until the Expiration
Date, retain the Shares which have been tendered during the period or periods
for which the Offer is extended. The Merger Agreement provides that the
Purchaser will not, without the prior written consent of the Company, decrease
the Offer Price or change the form of consideration payable in the Offer, waive
the Minimum Condition or decrease the number of Shares sought in the Offer, add
to the conditions of the Offer set forth in Section 14 below or amend any other
term of the Offer in any manner adverse to holders of Shares. Notwithstanding
the foregoing, (i) if any condition of the Offer (other than the Minimum
Condition) has not been satisfied or waived on any scheduled Expiration Date,
the Purchaser may, without the consent of the Company, (a) extend the Offer for
a period of time as is reasonably expected by the Purchaser to be necessary to
satisfy the unsatisfied conditions and (b) extend the Offer for any period
required by any rule, regulation, interpretation or position of the SEC or the
staff thereof applicable to the Offer, and (ii) if all of the conditions of the
Offer other than the Minimum Condition have been satisfied on any scheduled
Expiration Date, the Purchaser has agreed to extend the Offer for one additional
business day (or such longer time as may be agreed to by the Purchaser and the
Company), and to continue to effect such extensions until the earlier of (a) the
close of business on the business day immediately prior to the Special Meeting
and (b) the Minimum Condition has been satisfied, after which time the Purchaser
has agreed not to extend the Offer for any reason.
 
                                       3

<PAGE>

     Subject to the conditions described in the preceding paragraph, the
Purchaser expressly reserves the right, in its sole discretion, at any time or
from time to time, subject to the terms of the Merger Agreement and regardless
of whether or not any of the events set forth in Section 14 shall have occurred
or shall have been determined by the Purchaser to have occurred, to amend the
Offer in any respect by giving oral or written notice of such amendment to the
Depositary. The rights reserved by the Purchaser in this paragraph are in
addition to the Purchaser's rights to terminate the Offer pursuant to Section
14. Any extension, amendment or termination will be followed as promptly as
practicable by public announcement thereof, the announcement in the case of an
extension to be issued no later than 9:00 a.m., New York City time, on the next
business day after the previously scheduled Expiration Date in accordance with
Rules 14d-4(c), 14d-6(d) and 14e-1(d) under the Exchange Act. Without limiting
the obligation of the Purchaser under such rules or the manner in which the
Purchaser may choose to make any public announcement, the Purchaser currently
intends to make announcements by issuing a release to the Dow Jones News
Service.
 
     If the Purchaser extends the Offer, or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its purchase of or
payment for Shares or is unable to pay for Shares pursuant to the Offer for any
reason, then, without prejudice to the Purchaser's rights under the Offer, the
Depositary may retain tendered Shares on behalf of the Purchaser, and such
Shares may not be withdrawn except to the extent tendering shareholders are
entitled to withdrawal rights as described in Section 4. However, the ability of
the Purchaser to delay the payment for Shares which the Purchaser has accepted
for payment is limited by Rule 14e-1(c) under the Exchange Act, which requires

that a bidder pay the consideration offered or return the securities deposited
by or on behalf of holders of securities promptly after the termination or
withdrawal of the Offer.
 
     If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer
(including the Minimum Condition, subject to the Merger Agreement), the
Purchaser will disseminate additional tender offer materials and extend the
Offer to the extent required by Rules 14d-4(c) and 14d-6(d) under the Exchange
Act. The minimum period during which the Offer must remain open following
material changes in the terms of the Offer or information concerning the Offer,
other than a change in price or a change in percentage of securities sought,
will depend upon the facts and circumstances, including the relative materiality
of the terms or information. With respect to a change in price or a change in
percentage of securities sought, a minimum ten business day period is required
to allow for adequate dissemination to shareholders and investor response. If,
prior to the Expiration Date, the Purchaser should decide to increase the price
per Share being offered in the Offer, such increase will be applicable to all
shareholders whose Shares are accepted for payment pursuant to the Offer. The
Merger Agreement provides that, without the Company's consent, the Purchaser
will not decrease the price or the number of Shares sought in the Offer. As used
in this Offer to Purchase, 'business day' has the meaning set forth in Rule
14d-1 under the Exchange Act.
 
     The Company has provided the Purchaser with its list of shareholders and
security position listings for the purpose of disseminating the Offer to holders
of Shares. This Offer to Purchase and the related Letter of Transmittal and
other relevant materials will be mailed to record holders of Shares and
furnished to brokers, dealers, commercial banks, trust companies and similar
persons whose names, or the names of whose nominees, appear on the shareholder
list or, if applicable, who are listed as participants in a clearing agency's
security position listing, for subsequent transmittal to beneficial owners of
Shares.
 
2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES
 
     Upon the terms and subject to the conditions of the Offer (including, if
the Offer is extended or amended, the terms and conditions of any such extension
or amendment), the Purchaser will purchase, by accepting for payment, and will
pay for, all Shares validly tendered prior to the Expiration Date (and not
properly withdrawn in accordance with Section 4) promptly after the later to
occur of (i) the Expiration Date and (ii) any waiting period under the HSR Act
applicable to the purchase of Shares pursuant to the Offer having expired or
been terminated. Subject to the applicable rules of the SEC and the terms of the
Merger Agreement, the Purchaser expressly reserves the right to delay acceptance
for payment of, or payment for, Shares pending expiration of the waiting period
under the HSR Act applicable to the purchase of Shares pursuant to the Offer.
See Sections 14 and 15. The Purchaser understands that, in accordance with the
applicable rules of the SEC, any delay in accepting Shares regardless of cause
may not exceed an 'unreasonable length of time.' Accordingly, if it appears at
the time that the Offer is scheduled to expire that the expiration of the
waiting period under the HSR Act is not likely to be
 
                                       4


<PAGE>

obtained within a reasonable length of time thereafter, the Purchaser will
either extend the Offer or terminate the Offer.
 
     In all cases, payment for Shares purchased pursuant to the Offer will be
made only after timely receipt by the Depositary of (i) certificates evidencing
such Shares ('Share Certificates') or timely confirmation of a book-entry
transfer (a 'Book-Entry Confirmation') of such Shares into the Depositary's
account at The Depository Trust Company ('DTC' or the 'Book-Entry Transfer
Facility') pursuant to the procedures set forth in Section 3, (ii) a properly
completed and duly executed Letter of Transmittal (or facsimile thereof) or, in
the case of a book-entry transfer, an Agent's Message (as defined below) and
(iii) any other documents required by the Letter of Transmittal.
 
     The term 'Agent's Message' means a message, transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that the Book-Entry Transfer Facility has
received an express acknowledgment from the participant in the Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant. Participants in
DTC may tender their Shares in accordance with DTC's Automated Tender Offer
Program, to the extent it is available to such participants for the Shares they
wish to tender.
 
     For purposes of the Offer, the Purchaser will be deemed to have accepted
for payment, and thereby purchased, tendered Shares if, as and when the
Purchaser gives oral or written notice to the Depositary of the Purchaser's
acceptance of such Shares for payment. Payment for Shares accepted pursuant to
the Offer will be made by deposit of the purchase price with the Depositary,
which will act as agent for tendering shareholders for the purpose of receiving
payments from the Purchaser and transmitting payments to such tendering
shareholders. UNDER NO CIRCUMSTANCES WILL INTEREST ON THE PURCHASE PRICE FOR
SHARES BE PAID BY THE PURCHASER, REGARDLESS OF ANY DELAY IN MAKING SUCH PAYMENT.
 
     Upon the deposit of funds with the Depositary for the purpose of making
payments to tendering shareholders, the Purchaser's obligation to make such
payment shall be satisfied and tendering shareholders must thereafter look
solely to the Depositary for payment of amounts owed to them by reason of the
acceptance for payment of Shares pursuant to the Offer.
 
     If any tendered Shares are not accepted pursuant to the Offer for any
reason, or if Share Certificates are submitted evidencing more Shares than are
tendered, Share Certificates evidencing Shares not purchased or tendered will be
returned, without expense to the tendering shareholder (or in the case of Shares
tendered by book-entry transfer into the Depositary's account at the Book-Entry
Transfer Facility pursuant to the procedures set forth in Section 3, such Shares
will be credited to an account maintained at the Book-Entry Transfer Facility),
as promptly as practicable after the expiration, termination or withdrawal of
the Offer.
 
     The Purchaser reserves the right to transfer or assign, in whole at any

time or in part from time to time, to Parent or to one or more of its
affiliates, the right to purchase all or a portion of the Shares tendered
pursuant to the Offer, but any such transfer or assignment will not relieve the
Purchaser of its obligations under the Offer and will in no way prejudice the
rights of tendering shareholders to receive payment for Shares validly tendered
and accepted for payment pursuant to the Offer.
 
3. PROCEDURES FOR TENDERING SHARES
 
     Valid Tender.  For Shares to be validly tendered pursuant to the Offer, a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof), with any required signature guarantees, or an Agent's Message (in the
case of any book-entry transfer), and any other required documents, must be
received by the Depositary at its address set forth on the back cover of this
Offer to Purchase prior to the Expiration Date. In addition, either (i) the
Share Certificates evidencing Shares must be received by the Depositary along
with the Letter of Transmittal or Shares must be tendered pursuant to the
procedures for book-entry transfer described below and a Book-Entry Confirmation
must be received by the Depositary, in each case prior to the Expiration Date or
(ii) the tendering shareholder must comply with the guaranteed delivery
procedures described below.
 
     Book-Entry Transfer.  The Depositary will establish an account with respect
to the Shares at the Book-Entry Transfer Facility for purposes of the Offer
within two business days after the date of this Offer to Purchase, and any
financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-
 
                                       5

<PAGE>

entry delivery of Shares by causing the Book-Entry Transfer Facility to transfer
such Shares into the Depositary's account at the Book-Entry Transfer Facility in
accordance with the Book-Entry Transfer Facility's procedures for transfer.
However, although delivery of Shares may be effected through book-entry transfer
at the Book-Entry Transfer Facility, the Letter of Transmittal (or facsimile
thereof), with any required signature guarantees, or an Agent's Message in
connection with a book-entry delivery of Shares, and any other required
documents, must, in any case, be transmitted to and received by the Depositary
at its address set forth on the back cover of this Offer to Purchase prior to
the Expiration Date or the tendering shareholder must comply with the guaranteed
delivery procedures described below. DELIVERY OF DOCUMENTS TO THE BOOK-ENTRY
TRANSFER FACILITY IN ACCORDANCE WITH THE BOOK-ENTRY TRANSFER FACILITY'S
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
     Signature Guarantees.  Signatures on all Letters of Transmittal must be
guaranteed by a participant in the Security Transfer Agents Medallion Program
(each, an 'Eligible Institution'), unless the Shares tendered thereby are
tendered (i) by a registered holder of Shares who has not completed either the
box entitled 'Special Delivery Instructions' or the box entitled 'Special
Payment Instructions' on the Letter of Transmittal, or (ii) for the account of
an Eligible Institution. See Instruction 1 of the Letter of Transmittal.
 

     If a Share Certificate is registered in the name of a person other than the
signer of the Letter of Transmittal, or if payment is to be made, or a Share
Certificate not accepted for payment or not tendered is to be returned, to a
person other than the registered holder(s), then the Share Certificate must be
endorsed or accompanied by appropriate stock powers, in either case signed
exactly as the name(s) of the registered holder(s) appear on the Share
Certificate, with the signature(s) on such Share Certificate or stock powers
guaranteed as described above. See Instructions 1 and 5 of the Letter of
Transmittal.
 
     THE METHOD OF DELIVERY OF SHARE CERTIFICATES, THE LETTER OF TRANSMITTAL AND
ANY OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER AND THE

     Guaranteed Delivery.  If a shareholder desires to tender Shares pursuant to
the Offer and such shareholder's Share Certificates are not immediately
available or time will not permit all required documents to reach the Depositary
prior to the Expiration Date, or the procedures for book-entry transfer cannot
be completed on a timely basis, such Shares may nevertheless be tendered if all
the following conditions are satisfied:
 
          (i) the tender is made by or through an Eligible Institution;
 
          (ii) a properly completed and duly executed Notice of Guaranteed
     Delivery, substantially in the form provided by the Purchaser herewith, is
     received by the Depositary prior to the Expiration Date as provided below;
     and
 
          (iii) the Share Certificates for all tendered Shares, in proper form
     for transfer (or a Book-Entry Confirmation), together with a properly
     completed and duly executed Letter of Transmittal (or facsimile thereof),
     with any required signature guarantees (or, in the case of a book-entry
     transfer, an Agent's Message) and any other documents required by the
     Letter of Transmittal, are received by the Depositary within three New York
     Stock Exchange, Inc. ('NYSE') trading days after the date of execution of
     the Notice of Guaranteed Delivery.
 
     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by telegram, facsimile transmission or mail to the Depositary and must include a
guarantee by an Eligible Institution in the form set forth in the Notice of
Guaranteed Delivery.
 
     Notwithstanding any other provision hereof, payment for Shares purchased
pursuant to the Offer will in all cases be made only after timely receipt by the
Depositary of (i) Share Certificates evidencing such Shares or a Book-Entry
Confirmation of the delivery of such Shares, (ii) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's

<PAGE>

('TIN') AND CERTIFY THAT SUCH SHAREHOLDER IS NOT SUBJECT TO BACKUP WITHHOLDING.
IF A SHAREHOLDER DOES NOT PROVIDE SUCH SHAREHOLDER'S CORRECT TIN OR FAILS TO
PROVIDE THE CERTIFICATIONS DESCRIBED ABOVE, THE INTERNAL REVENUE SERVICE MAY
IMPOSE A PENALTY ON SUCH SHAREHOLDER AND PAYMENTS THAT ARE MADE TO SUCH
SHAREHOLDER WITH RESPECT TO SHARES PURCHASED PURSUANT TO THE OFFER MAY BE
SUBJECT TO BACKUP WITHHOLDING AT A RATE OF 31%. ALL SHAREHOLDERS SURRENDERING
SHARES PURSUANT TO THE OFFER SHOULD COMPLETE AND SIGN THE MAIN SIGNATURE FORM
AND THE SUBSTITUTE FORM W-9 INCLUDED AS PART OF THE LETTER OF TRANSMITTAL TO
PROVIDE THE INFORMATION AND CERTIFICATION NECESSARY TO AVOID BACKUP WITHHOLDING
(UNLESS AN APPLICABLE EXEMPTION EXISTS AND IS PROVED IN A MANNER SATISFACTORY TO
THE PURCHASER AND THE DEPOSITARY). SEE INSTRUCTION 9 AND 'IMPORTANT TAX
INFORMATION' IN THE LETTER OF TRANSMITTAL.
 
     Determination of Validity.  All questions as to the validity, form,
eligibility (including time of receipt) and acceptance for payment of any
tendered Shares pursuant to any of the procedures described above will be
determined by the Purchaser, in its sole discretion, whose determination will be
final and binding on all parties. The Purchaser reserves the absolute right to
reject any or all tenders of any Shares determined by it not to be in proper
form or if the acceptance for payment of, or payment for, such Shares may, in
the opinion of the Purchaser's counsel, be unlawful. The Purchaser also reserves
the absolute right, in its sole discretion, subject to the Merger Agreement, to
waive any of the conditions of the Offer or any defect or irregularity in any
tender with respect to Shares of any particular shareholder, and the Purchaser's
interpretation of the terms and conditions of the Offer (including the Letter of
Transmittal and the Instructions thereto) will be final and binding. None of the
Purchaser, Parent, the Dealer Manager, the Depositary, the Information Agent or
any other person will be under any duty to give notification of any defects or
irregularities in tenders or will incur any liability for failure to give any
such notification.
 
     Other Requirements.  By executing a Letter of Transmittal as set forth
above, a tendering shareholder irrevocably appoints designees of the Purchaser
as the shareholder's attorneys-in-fact and proxies, in the manner set forth in
the Letter of Transmittal, each with full power of substitution, to the full
extent of the shareholder's rights with respect to the Shares tendered by the
shareholder and accepted for payment by the Purchaser (and any and all other
Shares or other securities issued or issuable in respect of such Shares on or
after the date of the Merger Agreement). All such proxies shall be considered
coupled with an interest in the tendered Shares. This appointment will be
effective when, and only to the extent that, the Purchaser accepts Shares for
payment. Upon acceptance for payment, all prior proxies given by the shareholder
with respect to the Shares or other securities will, without further action, be
revoked, and no subsequent proxies may be given nor any subsequent written
consent executed by such shareholder (and if given or executed, will not be

deemed to be effective) with respect thereto. The designees of the Purchaser
will, with respect to the Shares and other securities, be empowered to exercise
all voting and other rights of such shareholder as they in their sole discretion
may deem proper at any annual, special or adjourned meeting of the Company's
shareholders, by written consent or otherwise. The Purchaser reserves the right
to require that, in order for Shares to be deemed validly tendered, immediately
upon the Purchaser's acceptance for payment of such Shares, the Purchaser must
be able to exercise full voting and other rights of a record and beneficial
holder, including rights in respect of acting by written consent, with respect
to such Shares.
 
     A tender of Shares pursuant to any one of the procedures described above
will constitute the tendering shareholder's acceptance of the terms and
conditions of the Offer. The Purchaser's acceptance for payment of Shares
tendered pursuant to the Offer will constitute a binding agreement between the
tendering shareholder and the Purchaser upon the terms and subject to the
conditions of the Offer.
 
4. WITHDRAWAL RIGHTS
 
     Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable, provided that Shares tendered pursuant to
the Offer may be withdrawn at any time prior to the Expiration Date and, unless
theretofore accepted for payment by the Purchaser pursuant to the Offer, may
also be withdrawn at any time after April 6, 1998, or at such later time as may
apply if the Offer is extended.
 
     For a withdrawal to be effective, a written, telegraphic or facsimile
transmission notice of withdrawal must be timely received by the Depositary at
its address set forth on the back cover of this Offer to Purchase. Any such
notice of withdrawal must specify the name of the person who tendered the Shares
to be withdrawn, the number of Shares to be withdrawn and the name of the
registered holder, if different from that of the person who tendered
 
                                       7

<PAGE>

such Shares. If Share Certificates evidencing Shares to be withdrawn have been
delivered or otherwise identified to the Depositary, then, prior to the physical
release of such Share Certificates, the serial numbers of the particular Share
Certificates and a signed notice of withdrawal with signatures guaranteed by an
Eligible Institution, except in the case of Shares tendered for the account of
an Eligible Institution, must also be furnished to the Depositary as described
above. If Shares have been tendered pursuant to the procedures for book-entry
transfer as set forth in Section 3, any notice of withdrawal must also specify
the name and number of the account at the Book-Entry Transfer Facility to be
credited with the withdrawn Shares.
 
     All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, whose determination will be final and binding. None of the
Purchaser, Parent, the Dealer Manager, the Depositary, the Information Agent or
any other person will be under any duty to give notification of any defects or

irregularities in any notice of withdrawal or incur any liability for failure to
give any such notification.
 
     ANY SHARES PROPERLY WITHDRAWN WILL BE DEEMED NOT TO HAVE BEEN VALIDLY
TENDERED FOR PURPOSES OF THE OFFER. However, withdrawn Shares may be re-tendered
by following one of the procedures described in Section 3 at any time prior to
the Expiration Date.
 
5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The receipt of cash for Shares pursuant to the Offer (or the Merger) will
be a taxable transaction for U.S. federal income tax law purposes and may also
be a taxable transaction under applicable state, local or foreign tax laws. The
tax consequences of such receipt pursuant to the Offer (or the Merger) may vary
depending upon, among other things, the particular circumstances of the
shareholder. In general, a shareholder who receives cash for Shares pursuant to
the Offer (or the Merger) will recognize gain or loss for U.S. federal income
tax purposes equal to the difference between the amount of cash received in
exchange for the Shares sold and such shareholder's adjusted tax basis in such
Shares.
 
     Provided that the Shares constitute capital assets in the hands of the
shareholder, such gain or loss will be capital gain or loss and, in the case of
an individual shareholder, will be taxable at various preferential rates
depending on the extent to which such shareholder's holding period for the
Shares sold pursuant to the Offer (or the Merger) exceeds one year. Gain or loss
will be calculated separately for each block of Shares (i.e., Shares acquired at
the same time and price) sold pursuant to the Offer (or the Merger). The
deduction of capital losses is subject to certain limitations.
 
     A shareholder that tenders Shares may be subject to backup withholding at a
rate of 31% unless such shareholder provides a correct TIN and certifies that
such shareholder is not subject to backup withholding, or unless an exemption
applies. See 'Backup Federal Income Tax Withholding' under Section 3 herein, and
Instruction 9 and 'Important Tax Information' in the Letter of Transmittal.
 
     THE U.S. FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
GENERAL INFORMATION ONLY AND IS BASED UPON PRESENT LAW. SHAREHOLDERS ARE URGED
TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF
THE OFFER (OR THE MERGER) TO THEM, INCLUDING THE APPLICATION AND EFFECT OF THE
ALTERNATIVE MINIMUM TAX, AND STATE, LOCAL AND FOREIGN TAX LAWS. IN ADDITION, THE
DISCUSSION SET FORTH ABOVE MAY NOT APPLY TO PARTICULAR CATEGORIES OF
SHAREHOLDERS, INCLUDING, FOR EXAMPLE, INDIVIDUALS WHO ARE NOT CITIZENS OR
RESIDENTS OF THE UNITED STATES, FOREIGN CORPORATIONS, LIFE INSURANCE COMPANIES,
TAX-EXEMPT ORGANIZATIONS, FINANCIAL INSTITUTIONS, AND HOLDERS WHO ACQUIRED
SHARES PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS
COMPENSATION.

     On January 30, 1998, the last full trading day prior to the announcement of
the terms of the Merger Agreement, the reported closing sales price per Share on
the NYSE was $25.125. On February 5, 1998, the last full trading day prior to
the commencement of the Offer, the reported closing sales price per Share on the
NYSE was $29.938. SHAREHOLDERS ARE URGED TO OBTAIN A CURRENT MARKET QUOTATION
FOR THE SHARES.
 
7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; EXCHANGE LISTING AND
EXCHANGE ACT REGISTRATION
 
     The purchase of Shares pursuant to the Offer will reduce the number of
Shares that might otherwise trade publicly and could reduce the number of
holders of Shares, which could adversely affect the liquidity and market value
of the remaining Shares held by the public. Following consummation of the Offer,
unless the Minimum Condition is waived or amended with the consent of the
Company, at least 90% of the outstanding Shares will be owned by Purchaser.
 
     According to the NYSE's published guidelines, the NYSE would consider
delisting the Shares if, among other things, the number of record holders of at
least 100 Shares should fall below 1,200, the number of publicly held Shares
(exclusive of holdings of officers, directors and their families and other
concentrated holdings of 10% or more (the 'NYSE Excluded Holdings')) should fall
below 600,000 or the aggregate market value of publicly held Shares (exclusive
of NYSE Excluded Holdings) should fall below $5,000,000. If, as a result of the
purchase of Shares pursuant to the Offer or otherwise, the Shares no longer meet
the requirements of the NYSE for continued listing and the listing of the Shares

is discontinued, the market for the Shares could be adversely affected.
 
     If the NYSE were to delist the Shares, it is possible that the Shares would
continue to trade on another securities exchange or in the over-the-counter
market and that price or other quotations would be reported by such exchange or
through the Nasdaq or other sources. The extent of the public market therefor
and the availability of such quotations would depend, however, upon such factors
as the number of shareholders and/or the aggregate market value of such
securities remaining at such time, the interest in maintaining a market in the
Shares on the part of securities firms, the possible termination of registration
under the Exchange Act as described below and other factors. The Purchaser
cannot predict whether the reduction in the number of Shares that might
otherwise trade publicly would have an adverse or beneficial effect on the
market price for or marketability of the Shares or whether it would cause future
market prices to be higher or lower than the Offer Price.
 
     The Shares are currently 'margin securities' under the regulations of the
Board of Governors of the Federal Reserve System (the 'Federal Reserve Board'),
which has the effect, among other things, of allowing brokers to extend credit
on the collateral of the Shares. Depending upon factors similar to those
described above regarding
 
                                       9

<PAGE>

listing and market quotations, following the Offer it is possible that the
Shares would no longer constitute 'margin securities' for the purposes of the
margin regulations of the Federal Reserve Board and therefore could no longer be
used as collateral for loans made by brokers.
 
     The Shares are currently registered under the Exchange Act. Such
registration may be terminated upon application by the Company to the SEC if the
Shares are not listed on a national securities exchange and there are fewer than
300 record holders of the Shares. The termination of registration of the Shares
under the Exchange Act would substantially reduce the information required to be
furnished by the Company to holders of Shares and to the SEC and would make
certain provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b), the requirement of furnishing a proxy statement in
connection with shareholders' meetings pursuant to Section 14(a), and the
requirements of Rule 13e-3 under the Exchange Act with respect to 'going
private' transactions, no longer applicable to the Shares. In addition,
'affiliates' of the Company and persons holding 'restricted securities' of the
Company may be deprived of the ability to dispose of such securities pursuant to
Rule 144 promulgated under the Securities Act of 1933, as amended. If
registration of the Shares under the Exchange Act were terminated, the Shares
would no longer be 'margin securities' or be eligible for NYSE listing. It is
the present intention of the Purchaser to seek to cause the Company to make an
application for termination of registration of the Shares under the Exchange Act
as soon as possible following the Offer if the requirements for termination of
registration are met.

million, respectively, for fiscal 1998, and projections of revenue, EBIT and net
income of approximately $413.9 million, $43.4 million and $25.1 million,
respectively, for fiscal 1999. The foregoing information was prepared by the
Company solely for internal use and not for publication or with a view to
complying with the published guidelines of the SEC regarding projections or with
the guidelines established by the American Institute of Certified Public
Accountants and are included in this Offer to Purchase only because they were
furnished to Parent. The foregoing information is 'forward-looking' and

business and economic conditions, changing competition, adverse changes in
applicable laws, regulations or rules governing environmental, tax or accounting
matters and other matters. One cannot predict whether the assumptions made in
preparing the foregoing information will be accurate, and actual results may be

the Company or anyone who received this information considered it a reliable
predictor of future events, and this information should not be relied on as
such. None of Parent, the Purchaser or the Company assumes any responsibility
for the validity, reasonableness, accuracy or completeness of the projections
and the Company has made no representation to Parent or the Purchaser regarding
the financial information described above.

     Contacts with the Company.  Except as set forth in this Offer to Purchase,
neither Parent, the Purchaser, Holdings or any other affiliate of Parent nor, to
the best knowledge of Parent, the Purchaser or Holdings, any of the persons

such persons (collectively, the 'Purchaser Entities'), beneficially owns any

guaranties against loss or the giving or withholding of proxies. Except as set
forth in this Offer to Purchase, no Purchaser Entity, or, to the best knowledge

executive officers, directors or affiliates, on the other hand, concerning a
merger, consolidation or acquisition, tender offer or other acquisition of
securities, election of directors, or a sale or other transfer of a material
amount of assets that would require reporting under the rules of the SEC.
 

     10. SOURCE AND AMOUNT OF FUNDS
 
     The total amount of funds required by the Purchaser to purchase all of the
Shares pursuant to the Offer, to repay outstanding indebtedness of the Company
and to pay related fees and expenses is approximately $460 million. The
Purchaser plans to obtain all funds needed for the Offer and the Merger through
a capital contribution from Parent.
 
     Parent intends to obtain the funds for its capital contribution through its
existing Credit Agreement, dated as of September 7, 1990, as amended, among
Parent and the banks listed therein (the 'Credit Facility'), and through a
committed credit line to be provided by the Bank of Nova Scotia (the 'Committed
Line'). The Credit Facility provides for revolving credit of up to $250 million
for general corporate purposes through September 30, 2001. At present, there
is no outstanding indebtedness under the Credit Facility. Loans under the
Credit Facility bear interest at one of the following rates, as selected by
Parent on the date of borrowing: (i) the Base Rate (as defined in the Credit
Facility); (ii) the Adjusted CD Rate (as defined in the Credit Facility);
or (iii) the Eurodollar Rate (as defined in the Credit Facility) plus, in
the case of (ii) and (iii), a margin ranging from 1/8 of one percent to
3/8 of one percent) based on the leverage ratio of Parent at the end
of the fiscal quarter most recently then ended. As of the date hereof, the
applicable margin would be 1/8 of one percent, which margin is expected to
increase to 1/4 of one percent based on the pro forma capitalization of Parent
after the Offer and the Merger. The effective interest rate as of the date
hereof would be approximately 6.0%. The Credit Facility contains covenants and
 
                                       13

<PAGE>

restrictions on the payment of dividends. The members of the bank group
providing the Credit Facility are Bankers Trust Company, Bank of America
Illinois, the First National Bank of Chicago, The Chase Manhattan Bank (National
Association), Bank of Nova Scotia, Industrial Bank of Japan, Bank of Tokyo,
NationsBank Corporation, Dresdner Bank Aktiengesellschaft, The Fuji Bank,
SunTrust Bank, The Northern Trust Company, Sumitomo Bank, Wachovia Bank of
Georgia, and Sanwa Bank. The Committed Line provides for credit of up to $250
million through a date 364 days following execution of final credit
documentation, under substantially the same terms and conditions as the Credit
Facility.
 
     The foregoing summary of the Credit Facility and the Committed Line is
qualified in its entirety by reference to the Credit Facility and the Committed
Line, which are filed as exhibits to Parent's and the Purchaser's Tender Offer
Statement on Schedule 14D-1 (the 'Schedule 14D-1') and incorporated herein by
reference.
 
     Although no definitive plan or arrangement for repayment of borrowings
under the Credit Facility or Committed Line has been made, Parent anticipates
such borrowings will be repaid with internally generated funds, (including, if
the Merger is accomplished, those of the Company) and from other sources which
may include the proceeds of future bank refinancings or the public or private
sale of debt or equity securities. No decision has been made concerning the

method Parent will use to repay the borrowings under the Credit Facility. Such
decision will be made based on Parent's review from time to time of the
advisability of particular actions, as well as prevailing interest rates,
financial and other economic conditions and such other factors as Parent may
deem appropriate.
 
     11. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY
 
     Parent regularly reviews possible acquisition candidates and, over the past
few years, has monitored the Company as a potential acquisition candidate.
 
     On December 9, 1997, the Company received an unsolicitated proposal by
Kollmorgen Corporation ('Kollmorgen') to acquire the Company. On December 15,
1997, Kollmorgen commenced a cash tender offer for a majority of the Shares at a
price of $20.50 per Share in cash, as disclosed in a Tender Offer Statement on
Schedule 14D-1 filed on December 15, 1997 (the 'Kollmorgen 14D-1'). In the
Kollmorgen 14D-1, Kollmorgen also proposed a merger with the Company pursuant to
which Shares not purchased in its tender offer would be converted into the right
to receive shares of common stock of Kollmorgen valued at $20.50 per share,
subject to certain limitations.
 
     Shortly after Kollmorgen's tender offer was commenced, Parent contacted the
Company about its possible interest in acquiring the Company. On January 9,
1998, Parent and Company executed a Confidentiality Letter Agreement (the
'Confidentiality Agreement') preceding Parent's review of certain information
about the Company. Parent received certain information from the Company about
its operations the week of January 12, 1998. During the week of January 19,
1998, representatives of Parent met with management of the Company to discuss
the Company's business and valuation parameters of the Company. In addition,
representatives of Parent visited various Company facilities.
 
     During the week of January 26, 1998, Parent and its representatives
conducted further financial, operational and legal due diligence investigation
of the Company. In addition, representatives of Parent and representatives of
the Company continued to discuss valuation parameters of the Company and the
general terms of a possible transaction, including pricing.
 
     On January 29, 1998, Parent provided the Company with a revised Merger
Agreement in response to a form of Merger Agreement furnished by the Company. On
January 30, 1998, representatives of Parent and representatives of the Company
began negotiating the terms of a definitive Merger Agreement. Also on January
30, Kollmorgen increased the price of its tender offer for a majority of the
Shares to $23.75 per Share.
 
     Negotiations between Parent and the Company continued through January 31,
1998, culminating in Parent and the Company agreeing upon a form of Merger
Agreement which was presented to and approved by Parent's Board of Directors and
by the Company's Board of Directors at meetings held on January 31, 1998,
subject to finalization of certain open items. The definitive Merger Agreement
was executed later that day. The transactions were publicly announced on
February 2, 1998.
 
                                       14


<PAGE>

     On February 2, 1998, Kollmorgen terminated its tender offer for a majority
of the Shares.
 
     On February 6, 1988, the Purchaser commenced the Offer.
 
     12. PURPOSE OF THE OFFER, THE MERGER AND THE MERGER AGREEMENT
 
     The purpose of the Offer, the Merger and the Merger Agreement is to enable
Parent to acquire control of, and the entire equity interest in, the Company.
Upon consummation of the Merger, the Company will become a subsidiary of
Holdings. The Offer is intended to increase the likelihood that the Merger will
be effected.
 
     Merger Agreement
 
     The following is a summary of certain provisions of the Merger Agreement.
The summary is qualified in its entirety by reference to the Merger Agreement
which is incorporated herein by reference and a copy of which has been filed
with the SEC as an exhibit to the Schedule 14D-1. The Merger Agreement may be
examined and copies may be obtained at the places and in the manner set forth in
Section 8 of this Offer to Purchase.
 
     The Offer.  The Merger Agreement provides that the Purchaser will commence
the Offer and that, upon the terms and subject to prior satisfaction or waiver
of the conditions of the Offer, as set forth in Section 14, the Purchaser will
accept for payment and pay for all Shares validly tendered pursuant to the
Offer. The Purchaser agreed to purchase all such Shares at a price of $30.25 per
Share. The Merger Agreement provides that the Purchaser will not, without the
prior written consent of the Company, reduce the number of Shares sought in the
Offer, reduce the Offer Price or change the form of consideration payable in the
Offer, waive the Minimum Condition or impose additional conditions or amend any
other term of the Offer set forth in Section 14 below or amend the Offer in any
manner adverse to the holders of Shares. Notwithstanding the foregoing, (i) if
any condition of the Offer (other than the Minimum Condition) has not been
satisfied or waived on any scheduled Expiration Date, the Purchaser may, without
the consent of the Company, (a) extend the Offer for a period of time as is
reasonably expected by the Purchaser to be necessary to satisfy the unsatisfied
conditions and (b) extend the Offer for any period required by any rule,
regulation, interpretation or position of the SEC or the staff thereof
applicable to the Offer and (ii) if all of the conditions of the Offer other
than the Minimum Condition have been satisfied on any scheduled Expiration Date,
the Purchaser has agreed to extend the Offer for one additional business day (or
such longer time as may be agreed to by the Purchaser and the Company), and to
continue to effect such extensions until the earlier of (a) the close of
business on the business day immediately prior to the Special Meeting and (b)
the Minimum Condition has been satisfied, after which time the Purchaser has
agreed not to extend the Offer for any reason.
 
     One-Step Transaction.  As indicated above, the Merger Agreement
contemplates a two-step transaction in which, following consummation of the
Offer, the Merger occurs. Under the GCL, if the Purchaser acquires, pursuant to
the Offer or otherwise, at least 90% of the then outstanding Shares, the

Purchaser will be able to approve and adopt the Merger and the Merger Agreement
without a vote of the Company's shareholders. However, under the GCL, the Merger
may not be accomplished for cash paid to the remaining Company shareholders if
the Purchaser, Holdings or Parent owns directly or indirectly more than 50% but
less than 90% of the then outstanding Shares unless either all of the
shareholders of the Company consent to the Merger or the Commissioner of
Corporations of the State of California approves, after a hearing, the terms and
conditions of the Merger and the fairness thereof. Accordingly, Parent and the
Company intend to proceed simultaneously with an alternative to this two-step
transaction in which the Company pursues a one-step cash merger at the Offer
Price. This one-step transaction would require the affirmative vote of a
majority of the Company's outstanding voting stock. In the event the Minimum
Condition is not fulfilled, the Merger Agreement contemplates that the Offer
will be terminated and Parent and the Company will seek to implement the
one-step cash merger transaction.
 
     Pursuant to the Merger Agreement, the Company has agreed to duly call, give
notice of, convene and hold the Special Meeting as soon as practicable following
the date of the Merger Agreement for the purpose of considering and taking
action upon the Merger and the adoption of the Merger Agreement pursuant to a
one-step cash merger. The Merger Agreement provides that the Company will
prepare and file with the SEC a preliminary proxy statement and cause a
definitive proxy statement relating to the Special Meeting to be mailed to its
shareholders for the purpose of obtaining the necessary approvals of the Merger
and the Merger Agreement from its shareholders. The Board of Directors of the
Company, subject to the provisions described under 'No Solicitation' below has
agreed to include in the proxy statement its recommendation that the
shareholders of the
 
                                       15

<PAGE>

Company vote in favor of the approval of the Merger and the Merger Agreement.
The affirmative vote of a majority of the outstanding Shares would be required
to approve the Merger and the Merger Agreement at the Special Meeting. However,
if the Minimum Condition and the other conditions to the Offer are satisfied
prior to the Special Meeting, the Purchaser will acquire at least 90% of the
Shares outstanding and will be able to approve and adopt the Merger without a
vote of the Company's shareholders and the Special Meeting will be cancelled.
 
     Recommendation.  The Merger Agreement provides that, subject to the
conditions thereof, the Board of Directors of the Company has (i) determined
that the Offer and the Merger are fair and in the best interests of the Company
an its shareholders, (ii) approved an amendment to the Rights Agreement such
that the Purchaser does not become an 'Acquiring Person' thereunder to the
extent of its acquisition of Shares pursuant to the Merger Agreement and (iii)
resolved to recommend acceptance of the Offer and approval and adoption of the
Merger and the Merger Agreement by the Company's shareholders.
 
     The Merger.  Following the consummation of the Offer, the Merger Agreement
provides that, subject to the terms and conditions thereof, and in accordance
with California law, the Purchaser will be merged with and into the Company. As
a result of the Merger, the separate corporate existence of the Purchaser will

cease and the Company will continue as the Surviving Corporation. The time the
Merger becomes effective is referred to as the 'Effective Time.'
 
     Conversion of Shares.  At the Effective Time, each Share issued and
outstanding immediately prior to the Effective Time (other than Shares held by
Holdings, the Purchaser, any wholly owned subsidiary of Holdings or the
Purchaser, in the treasury of the Company or by any wholly owned subsidiary of
the Company, which Shares, by virtue of the Merger and without any action on the
part of the holder thereof, will be canceled and retired and will cease to exist
with no payment being made with respect thereto, and shareholders who perfect
their dissenters' rights under California law) will be converted into the right
to receive in cash the Offer Price. At the Effective Time, each issued and
outstanding share of the Purchaser will be converted into one validly issued,
fully paid and nonassessable share of common stock, par value $1.00 per share,
of the Surviving Corporation.
 
     Pursuant to the Merger Agreement, immediately following the Effective Time,
each holder of an outstanding Option granted under any Stock Plan, whether or
not fully exercisable, will be entitled to receive in settlement of such Option
a cash payment from the Company equal to the product of (i) the total number of
Shares previously subject to such Option and (ii) the excess of the Offer Price
over the exercise price per Share subject to such Option, subject to any
required withholding of taxes.
 
     Dissenting Shares.  If the Merger is consummated, Shares outstanding
immediately prior to the Effective Time and held by a shareholder who has not
voted in favor of the Merger and who has perfected such shareholder's right to
demand cash payment for the fair market value of such holder's Shares in
accordance with Chapter 13 of the GCL will not be converted into a right to
receive the Offer Price, unless such shareholder fails to perfect or withdraws
or otherwise loses such shareholder's right to a determination of the fair
market value of such shareholder's Shares under the GCL, in which case such
Shares will be treated as if they have been converted as of the Effective Time
into a right to receive the Offer Price. The Company has agreed to give Holdings
prompt notice of any dissenting shareholders and Holdings will have the right to
participate in all negotiations and proceedings with respect to such demands.
See Section 15.
 
     Board of Directors.  Promptly upon the purchase by the Purchaser of Shares
representing at least such number of Shares as shall satisfy the Minimum
Condition, and from time to time thereafter, Holdings shall be entitled to
designate up to such number of directors, rounded up to the next whole number,
on the Board of Directors of the Company as is equal to the number of directors
which is the product of (a) the total number of directors on the Board of
Directors of the Company (giving effect to the directors elected pursuant to
this sentence) multiplied by (b) the percentage that the aggregate number of
Shares beneficially owned by Holdings or its affiliates bears to the total
number of Shares then outstanding on a fully diluted basis. Notwithstanding the
foregoing, the Company, Holdings and the Purchaser have agreed that, until the
Effective Time, the Board of Directors of the Company shall have at least two
Independent Directors; provided, however, that, in such event, if the number of
Independent Directors shall be reduced below two, the remaining Independent
Director shall be entitled to designate a person to fill such a vacancy who
shall not be an officer, director or designee of the Purchaser or any of its

affiliates and who shall be deemed to be an Independent Director for purposes of
the Merger Agreement. In the Merger Agreement, the Company has agreed, upon
request of Holdings, to take all
 
                                       16

<PAGE>

actions necessary to cause Holdings' designees to be so elected, including
mailing to its shareholders the Information Statement containing the information
required by Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder, and, if necessary, seeking the resignation of one or more existing
directors.
 
     The Rights Agreement.  The Company has distributed one Right for each
outstanding Share pursuant to the Rights Agreement. The Company has represented
in the Merger Agreement that it has taken all action which may be necessary
under the Rights Agreement and has, on January 31, 1998, amended the Rights
Agreement, so that the execution of the Merger Agreement, the making of the
Offer, the acquisition of Shares pursuant to the Offer and the consummation of
the Merger will not cause (i) any Rights issued pursuant to the Rights Agreement
to become exercisable or to separate from the stock certificates to which they
are attached, (ii) Holdings, the Purchaser, or any of their affiliates to become
an Acquiring Person (as defined in the Rights Agreement), or (iii) trigger other
provisions of the Rights Agreement, including giving rise to a Distribution Date
(as defined in the Rights Agreement).
 
     Representations and Warranties.  Pursuant to the Merger Agreement, the
Company has made customary representations and warranties to Holdings and the
Purchaser with respect to, among other things, its organization and
subsidiaries, capitalization, authority, the absence of violations, financial
statements, public filings, compliance with law, litigation, information in the
proxy statement, employee benefit plans, tax matters, intellectual property,
contracts, the absence of any material adverse effects on the Company since
December 27, 1996, the Rights Agreement and the opinion of its financial
advisor. Holdings and the Purchaser have made customary representations and
warranties to the Company with respect to, among other things, its organization,
authority, the absence of violations, information in the proxy statement and
financing.
 
     Covenants.  The Merger Agreement contains certain covenants of the Company,
Holdings and the Purchaser in contemplation of the Merger, including, without
limitation, access by Holdings and the Purchaser to information concerning the
Company, use of reasonable best efforts to consummate the Merger, use of
reasonable best efforts to obtain all consents necessary for the consummation of
the Merger, and notification of the other parties of certain matters.
 
     Conduct of Business of the Company.  Pursuant to the Merger Agreement, the
Company agreed that, except with the prior written consent of Holdings, during
the period from the date of the Merger Agreement to the Effective Time, the
Company and each of its subsidiaries will conduct its operations according to
its ordinary and usual course of business and consistent with past practice and
will use reasonable efforts to preserve intact the business organization of the
Company and each of its subsidiaries, to keep available the services of its and

their present officers and key employees, and to preserve the good will of those
having business relationships with it. The Company has also agreed that except
as (a) otherwise expressly provided in the Merger Agreement, (b) required by
law, (c) previously disclosed to Parent in the Company's 1998 operating budget,
or (d) set forth on the Company's disclosure schedule, prior to the Effective
Time, the Company and its subsidiaries will not, without the prior written
consent of Holdings:
 
          (i) except with respect to annual bonuses made in the ordinary course
     of business consistent with past practice, adopt or amend in any material
     respect any bonus, profit sharing, compensation, severance, termination,
     stock option, stock appreciation right, pension, retirement, employment or
     other employee benefit agreement, trust, plan or other arrangement for the
     benefit or welfare of any director, officer or employee of the Company or
     any of its subsidiaries or increase in any manner the compensation or
     fringe benefits of any director, officer or employee of the Company or any
     of its subsidiaries or pay any benefit not required by any existing

     Employee Benefits.  Holdings has agreed to cause the Surviving Corporation
to honor the employment, severance and bonus arrangements to which the Company
is a party. Holdings has also agreed that for a period of two years following
the Effective Time, the Surviving Corporation will provide employees of the
Company and its subsidiaries compensation and employee benefit and welfare plans
which are not materially less favorable in the aggregate to such employee than
those generally in effect on the date of the Merger Agreement with respect to
similarly situated employees of the Company.

 
     No Solicitation.  Pursuant to the Merger Agreement, the Company has agreed
that it will cause its subsidiaries and its and their officers, directors,
employees, investment bankers, attorneys and other agents and representatives
to, immediately cease any existing discussions or negotiations with any person
other than Holdings or the Purchaser (a 'Third Party') with respect to any
Acquisition Transaction (as hereinafter defined). The Company has also agreed
that it will not, and will cause its subsidiaries and its and their officers,
directors, employees, investment bankers, attorneys and other agents and
representatives not to, directly or indirectly,
 
                                       18

<PAGE>

(w) solicit, initiate, continue, facilitate or encourage (including by way of
furnishing or disclosing non-public information) any inquiries, proposals or
offers from any Third Party with respect to, or that could reasonably be
expected to lead to, any acquisition or purchase of a material portion of the
assets (other than in the ordinary course of business) or business of, or any
significant equity interest in (including by way of a tender offer), or any
merger, consolidation or business combination with, or any recapitalization or
restructuring, or any similar transaction involving, the Company or any of its
subsidiaries (the foregoing being referred to collectively as an 'Acquisition
Transaction') or (x) negotiate, explore or otherwise communicate in any way with
any Third Party with respect to any Acquisition Transaction; or (y) enter into,
approve or recommend any agreement, arrangement or understanding requiring the
Company to abandon, terminate or fail to consummate the Offer and/or the Merger
or any other transaction contemplated thereby; or (z), withdraw or modify, or
propose publicly to withdraw or modify, in a manner adverse to Holdings, the
approval or recommendation by the Company's Board of Directors of the Offer, the
Merger or the Merger Agreement; provided, however, that nothing in the Merger
Agreement will prevent the Company's Board of Directors from taking, and
disclosing to the Company's shareholders, a position contemplated by Rules 14d-9
and 14e-2 promulgated under the Exchange Act with respect to any tender offer.
The Company has agreed to promptly notify Holdings of the receipt of any
proposal relating to an Acquisition Transaction. Notwithstanding anything to the
contrary in the foregoing, the Company may, in response to an unsolicited
written proposal with respect to an Acquisition Transaction involving the
acquisition of all of the Shares (or all or substantially all of the assets of
Company and its subsidiaries) from a Third Party, (i) furnish or disclose
non-public information to such Third party and (ii) negotiate, explore or
otherwise communicate with such Third Party, in each case only if (a) after
being advised by (x) its outside counsel with respect to its fiduciary
obligations and (y) its financial advisors with respect to the financial terms
of any such proposed Acquisition Transaction, the Board of Directors of the
Company determines in good faith by a majority vote that taking such action is
necessary in the exercise of its fiduciary obligations under applicable law (the
proposal with respect to an Acquisition Transaction meeting the requirements of
this clause (a), a 'Superior Proposal'), and (b) prior to furnishing or
disclosing any non-public information to, or entering into discussions or
negotiations with, such Third Party, the Company receives from such Third Party
an executed confidentiality agreement (which the Company is expressly permitted
to negotiate with such party) with terms no less favorable in the aggregate to

Company than those contained in the Confidentiality Agreement but which
confidentiality agreement shall not provide for any exclusive right to negotiate
with the Company or any payments by the Company and need not contain any
'stand-still' or similar provisions. In addition, the Company's Board of
Directors may approve or recommend (and, in connection therewith withdraw or
modify its approval or recommendation of the Offer, the Merger Agreement or the
Merger) a Superior Proposal and may terminate the Merger Agreement solely to
enter into a definitive agreement with respect to a Superior Proposal; provided,
however, that Company may not, and will cause its affiliates not to, enter into
a definitive agreement with respect to a Superior Proposal unless the Company
concurrently terminates the Merger Agreement in accordance with the terms
thereof and pays any amounts required under the Merger Agreement, as described
under 'Fees and Expenses' below.
 
     The Merger Agreement provides that the Company will promptly (but in any
event within one business day of Company becoming aware of same) advise Holdings
of the receipt by the Company, any of its subsidiaries or any of Company's
bankers, attorneys or other agents or representatives of any written inquires or
proposals relating to an Acquisition Transaction and any actions taken pursuant
to provisions of the Merger Agreement described in the immediately preceding
paragraph and the Company will promptly (but in any event within one business
day of the Company becoming aware of same) provide Parent with a copy of any
such written inquiry or proposal. The Company will keep Holdings reasonably
informed of the status and content of and material developments (including the
calling of meetings of the Company's Board of Directors to take action with
respect to such Acquisition Transaction) with respect to any discussions
regarding any Acquisition Transaction with a Third Party. The Company agrees
that it will not enter into any agreement with respect to a Superior Proposal
unless and until Holdings has been given notice of the identity of the parties
making such Superior Proposal, the material terms thereof and material
developments referred to in the preceding sentence at least two business days
prior to the entering into such agreement.
 
     Indemnification; Directors' and Officers' Insurance.  Pursuant to the
Merger Agreement, from and after the Effective Time, Holdings has agreed, and
will cause the Surviving Corporation to, indemnify the present and former
officers, directors, employees and agents of the Company and its subsidiaries
(the 'Indemnified Parties')
 
                                       19

<PAGE>

against all losses, claims, damages, expenses or liabilities arising out of or
related to actions or alleged actions or omissions occurring at or prior to the
Effective Time to the full extent permitted under California law or, if greater,
in the Company's Restated Articles of Incorporation and By-Laws and agreements
(including indemnification agreements to which directors or officers of the
Company or its subsidiaries are parties) between the Company or one of its
subsidiaries and such employee, in effect on the date of the Merger Agreement
and identified to Purchaser by the Company (to the extent consistent with
applicable law), which provisions and agreements will survive the Merger and
continue in full force and effect. If such Indemnified Party becomes involved in
any action or proceeding, Holdings has agreed to advance reasonable legal and

other expenses as incurred by an Indemnified Party, provided, however, Holdings
will not, in connection with one action or separate but substantially similar
actions arising out of the same general allegations, be liable for fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) at any time for all Indemnified Parties, except in certain
circumstances. Parent will be entitled to participate in the defense of any such
action or proceeding. In addition, pursuant to the Merger Agreement, Holdings
has agreed to maintain the current policies for officers and director liability
insurance for not less than six years from the Effective Time.
 
     Merger Conditions.  In the event the Offer is consummated, the obligations
of the parties to consummate the Merger would be subject to the satisfaction, at
or before the Effective Time, of each of the following conditions: (i) the
shareholders of the Company having duly approved the transactions contemplated
by the Merger Agreement, if required by applicable law or the Restated
Certificate of Incorporation of the Company; (ii) no statute, rule, regulation,
executive order, decree or injunction having been enacted, entered, promulgated
or enforced by any court of competent jurisdiction or other governmental entity
which prohibits the consummation of the Merger; provided, however, that the
Company, Holdings and the Purchaser will use their reasonable best efforts to
have any such order, decree or injunction vacated; or (iv) any waiting period
(any extension thereof) under the HSR Act applicable to the Merger having
expired or terminated.
 
     If the Offer has not been consummated, the obligations of Holdings to
consummate the Merger pursuant to a one-step transaction are subject to the
satisfaction, at or before the Effective Time, of the conditions described in
the immediately preceding paragraph and the following additional conditions: (i)
the representations and warranties of the Company set forth in the Merger
Agreement being true and correct in all respects in each case as of the date of
the Merger Agreement and as of the closing date of the Merger (the 'Closing
Date') as though made on and as of the Closing Date; provided, however, that,
with respect to representations and warranties other than those with respect to
the Company's capitalization and subsidiaries and the Company's authority to
enter in the Merger Agreement and the transactions contemplated thereby and
representations and warranties otherwise qualified by material adverse effect,
such representations and warranties and statements will be deemed to be true and
correct in all respects unless the failure or failures of such representations
and warranties and statements to be so true and correct, individually or in the
aggregate would result in a material adverse effect on the Company; (ii) the
Company having performed the obligations required to be performed by it under
the Merger Agreement at or prior to the Closing Date, except for such failures
to perform as have not had or would not, individually or in the aggregate, have
a material adverse effect on the Company or materially adversely affect the
ability of the Company to consummate the transactions contemplated by the Merger
Agreement; and (iii) Holdings having received evidence, in form and substance
reasonably satisfactory to it, that all licenses, permits, consents, approvals,
authorizations, qualifications and orders of governmental authorities and other
third parties relating to the Merger have been obtained.
 
     If the Offer has not been consummated, the obligations of the Company to
effect the Merger pursuant to a one-step transaction are subject to the
satisfaction, at or before the Effective Time, of the conditions in the first
paragraph of this subsection and the following additional conditions: (i) the

representations and warranties of Holdings and the Purchaser set forth in the
Merger Agreement being true and correct in all respects in each case as of the
date of the Merger Agreement and as of the Closing Date as though made on and as
of the Closing Date; provided, however, that, with respect to representations
and warranties other than those with respect to Holdings' and the Purchaser's
authority to enter into the Merger Agreement and the transactions contemplated
thereby, and representations and warranties otherwise qualified by material
adverse effect on Holdings, such representations and warranties will be deemed
to be true and correct in all respects unless the failure or failures of such
representations and warranties and statements to be so true and correct,
individually or in the aggregate would result in a material adverse effect on
Holdings; and (ii) each of Holdings and the Purchaser having performed the
 
                                       20

<PAGE>

obligations required to be performed by it under the Merger Agreement at or
prior to the Closing Date, except for such failures to perform as have not had
or would not reasonably be expected individually or in the aggregate, to have a
material adverse effect on Holdings or adversely affect the ability of Holdings
or the Purchaser to consummate the transactions contemplated by the Merger
Agreement.
 
     Termination.  The Merger Agreement may be terminated and the Merger may be
abandoned at any time prior to the Effective Time, whether or not approval
thereof by the shareholders has been obtained:
 
          (a) by the mutual written consent of Parent and the Company, by action
     of their respective Board of Directors;
 
          (b) by the Company if the Company is not in material breach of any of
     its representations, warranties, covenants or agreements contained in the
     Merger Agreement and if (i) Holdings or the Purchaser fails to commence the
     Offer, or (ii) (x) at or any time following the initial Expiration Date as
     it may be extended pursuant to the terms of the Merger Agreement, the
     Minimum Condition shall have been satisfied and all other conditions to the
     Offer shall have been satisfied or waived in accordance with the terms
     hereof and (y) Holdings or the Purchaser shall not have accepted for
     payment and paid for Shares pursuant to the Offer in accordance with the
     terms of the Merger Agreement;
 
          (c) by Parent or the Company if the Merger shall not have been
     consummated on or before June 30, 1998; provided, however, that neither
     Holdings nor the Company may terminate the Merger Agreement as described in
     this clause (c) if such party shall have materially breached the Merger
     Agreement; and provided, further, that Holdings may not terminate the
     Merger Agreement as described in this clause (c) if the Offer shall have
     theretofore been consummated;
 
          (d) by Holdings or the Company if any court of competent jurisdiction
     in the United States or other United States governmental entity has issued
     an order, decree or ruling or taken any other action restraining, enjoining
     or otherwise prohibiting the Merger and such order, decree, ruling or other

     action shall have become final and nonappealable; provided, however, that
     the party seeking to terminate the Merger Agreement shall have used its
     reasonable best efforts to remove or lift such order, decree, ruling or
     other action;
 
          (e) by the Company if, prior to the acceptance for payment of Shares
     pursuant to the Offer, (i) there shall have occurred, on the part of
     Holdings or Purchaser, a material breach of any representation or warranty,
     covenant or agreement contained in the Merger Agreement which is not
     curable or (ii) the Company (A) to the extent permitted by the provisions
     of the Merger Agreement described under 'No Solicitation' above, enters
     into a definitive agreement with respect to a Superior Proposal and (B)
     concurrently pays any termination fee and agrees to pay any other amounts
     required under the Merger Agreement, as described under 'Fees and Expenses'
     below;
 
          (f) by Parent if the Company breaches its covenant not to amend the
     Rights Agreement or redeem the Rights, provided, however, that such breach
     occurs prior to the time that designees of Holdings constitute a majority
     of the Company's Board of Directors; or
 
          (g) by Holdings, prior to the purchase of Shares pursuant to the
     Offer, if (i) there shall have occurred, on the part of the Company, a
     breach of any representation, warranty, covenant or agreement contained in
     the Merger Agreement which (except in the case of a breach of certain of
     the representations and warranties) individually or in the aggregate if not
     cured would be reasonably likely to have a material adverse effect on the
     Company and which is not curable or (ii) the Company's Board of Directors
     shall have withdrawn or modified (including by amendment of the Company's
     Solicitation/Recommendation Statement on Schedule 14D-9) in a manner
     adverse to the Purchaser its approval or recommendation of the Offer, the
     Merger Agreement or the Merger, shall have approved or recommended a
     Superior Proposal, or shall have resolved to effect any of the foregoing.
 
     Fees and Expenses.  The Merger Agreement provides that whether or not the
Merger is consummated, except as otherwise provided below, all costs and
expenses incurred in connection with the Offer, the Merger Agreement and the
transactions contemplated thereby shall be paid by the party incurring such
expenses.
 
     In the event the Merger Agreement is terminated as described in clause
(e)(ii), (f) or (g)(ii) under 'Termination' above, then the Company will
promptly pay the documented fees and expenses of Holdings and
 
                                       21

<PAGE>

the Purchaser related to the Merger Agreement, the transactions contemplated
thereby and any related financing (subject to a maximum of $2.0 million) and in
the event the Merger Agreement is terminated as described in clause (e)(ii) or
(g)(ii) under 'Termination' above, then the Company will promptly pay Holdings a
termination fee of $15 million (the 'Termination Fee'); provided that in no
event shall more than one Termination Fee be paid by the Company.

 
     The Merger Agreement also provides that in the event that (i) any person
shall have publicly disclosed a proposal regarding an Acquisition Transaction
and (ii) following such disclosure (and provided that neither Holdings nor the
Purchaser is in any material breach of any of its representations, warranties,
covenants or agreements contained in the Merger Agreement), either (x) June 30,
1998 occurs without the Minimum Condition being satisfied (other than as a
result of a material breach thereof by Holding or the Purchaser that has not
been cured) or the requisite shareholder approval of the Merger being obtained
or (y) if the Merger Agreement is terminated as described in clause (f) or
(g)(ii) under 'Termination' above, and (iii) not later than six months after any
such termination the Company shall have entered into an agreement for an
Acquisition Transaction, or an Acquisition Transaction shall have been
consummated, then the Company will promptly, but in no event later than
immediately prior to, and as a condition of, entering into such definitive
agreement, or, if there is no such definitive agreement then immediately upon
consummation of the Acquisition Transaction, pay Parent a Termination Fee of $15
million.
 
     Extension; Waiver.  Subject to the terms of the Merger Agreement, at any
time prior to the Effective Time, the parties may (i) extend the time for the
performance of any of the obligations or other acts of the other, (ii) waive any
inaccuracies in the representations and warranties contained in the Merger
Agreement or in any other document delivered pursuant to the Merger Agreement by
the other, or (iii) waive compliance by the other with any of the agreements or
conditions.
 
     Confidentiality Agreement
 
     Pursuant to the Confidentiality Agreement, Parent and the Company agreed to
provide, among other things, for the confidential treatment of their discussions
regarding the Offer and the Merger and the exchange of certain confidential
information concerning the Company. The Confidentiality Agreement is
incorporated herein by reference and a copy of it has been filed with the SEC as
an exhibit to the Schedule 14D-1. The Confidentiality Agreement may be examined
and copies may be obtained at the places and in the manner set forth under the
heading 'Available Information' in Section 8 of this Offer to Purchase.
 
     Other Matters
 
     Articles of Incorporation.  Article Fifth of the Company's Restated
Articles of Incorporation ('Article Fifth') provides that the adoption of any
agreement for the merger of the Company with, or sale or other disposition of
all or substantially all of the assets of the Company (or in any case greater
than 50% of the then fair market value thereof) to a person that is an
'associate' of the Company (an 'Acquiring Associate') requires (a) the
affirmative vote of the holders of at least a majority of the outstanding shares
of stock of the Company entitled to vote exclusive of shares owned beneficially
by the Acquiring Associate, and (b) the affirmative vote of holders of at least
two-thirds of the outstanding shares of the stock of the Company entitled to
vote. Shares held beneficially by an Acquiring Associate include the shares
beneficially owned by any affiliate or associate of such person and shares such
person or its affiliates or associates have the right to acquire pursuant to
agreement or with respect to which such person or its affiliates or associates

have any agreement or understanding for the purposes of acquiring, holding,
voting or disposing of voting securities of the Company. Article Fifth thus has
the effect of increasing the voting requirements that would otherwise be
required under applicable law for approval of extraordinary transaction to which
it applies.
 
     Under the Article Fifth, (a) an 'associate' of a specified person is (i)
any person who is, directly or indirectly, the beneficial owner of 5% or more of
any class of equity securities of such specified person or who is an officer,
director, trustee or partner of such specified person or any affiliate of such
specified person, (ii) any trust or estate in which such specified person has a
substantial beneficial interest or as to which such specified person serves as a
trustee or in a similar fiduciary capacity, and (iii) any relative or spouse of
such specified person, or any relative of such spouse, having the same home as
specified person; and (b) an 'affiliate' of a specified person is any other
person that directly or indirectly through one or more intermediaries controls,
or is controlled by, or is under common control with the specified person.
 
                                       22

<PAGE>

     The enhanced voting requirements of Article Fifth do not apply under
certain circumstances, including any transaction (a) between the Company and its
wholly owned subsidiaries; (b) that is merger for which approval of the
Company's shareholders is not required under California law; (c) that is a
merger in which the Company is the surviving entity; or (iv) that has been
approved by the Company's Board of Directors either unanimously or prior to the
acquisition by any associate of the Company of the beneficial ownership of 5% or
more of the outstanding Common Stock.
 
     The Company's Board of Directors has unanimously approved the Offer and the
Merger with the effect that the voting requirements of Article Fifth are not
applicable to the Merger.
 
     Short-Form Merger.  Under the GCL, the affirmative vote of holders of a
majority of the outstanding Shares entitled to vote, including any Shares owned
by the Purchaser, would be required to adopt the Merger. However, the GCL also
provides that if a parent company owns at least 90% of each class of stock of a
subsidiary, the parent company can effect a merger with the subsidiary without
the authorization of the other shareholders of the subsidiary. Accordingly, if,
as a result of the Offer the Purchaser acquires at least 90% of the outstanding
Shares (which would be the case if the Minimum Condition is satisfied), the
Purchaser could, and intends to, effect the Merger without approval of any other
shareholder of the Company.
 
     Dissenters' Rights.  Holders of Shares do not have dissenters' rights as a
result of the Offer. However, in connection with the Merger, holders of Shares,
by complying with the provisions of Chapter 13 of the GCL, may have certain
rights to dissent and to require the Company to purchase their Shares for cash
at 'fair market value.' In general, holders of Shares will be entitled to
exercise dissenters' rights under the GCL only if the holders of five percent or
more of the outstanding Shares properly file demands for payment or if the
Shares held by such holders are subject to any restriction on transfer imposed

by the Company or any law or regulation ('Restricted Shares'). Accordingly, any
holder of Restricted Shares and, if the holders of five percent or more of the
Shares properly file demands for payment, all other such holders who fully
comply with all other applicable provisions of Chapter 13 of the GCL will be
entitled to require the Company to purchase their Shares for cash at their 'fair
market value' if the Merger is consummated. In addition, if immediately prior to
the Effective Time, the Shares are not listed on a national securities exchange
such as the NYSE or on the list of OTC margin stocks issued by the Federal
Reserve Board, holders of Shares may likewise exercise their dissenters' rights
as to any or all of their Shares entitled to such rights. If the statutory
procedures under the GCL relating to dissenters' rights were complied with, such
rights could lead to a judicial determination of the fair market value of the
Shares. The 'fair market value' would be determined as of the day before the
first announcement of the terms of the Merger, excluding any appreciation or
depreciation as a consequence of the Merger. The value so determined could be
more or less than the Offer Price.
 
     Rule 13e-3.  The SEC has adopted Rule 13e-3 under the Exchange Act which is
applicable to certain 'going private' transactions and which may under certain
circumstances be applicable to the Merger or another business combination
following the purchase of Shares pursuant to the Offer in which the Purchaser
seeks to acquire the remaining Shares not held by it. The Purchaser believes,
however, that Rule 13e-3 will not be applicable to the Merger because it is
anticipated that the Merger will be effected within one year following
consummation of the Offer. Rule 13e-3 requires, among other things, that certain
financial information concerning the Company and certain information relating to
the fairness of the proposed transaction and the consideration offered to
minority shareholders in such transaction be filed with the SEC and disclosed to
shareholders prior to consummation of the transaction.
 
     General.  The Purchaser or an affiliate of the Purchaser may, following the
consummation or termination of the Offer, seek to acquire additional Shares
through open market purchases, privately negotiated transactions, a tender offer
or exchange offer or otherwise, upon such terms and at such prices as it shall
determine, which may be more or less than the price to be paid pursuant to the
Offer. The Purchaser and its affiliates also reserve the right to dispose of any
or all Shares acquired by them.
 
     Upon the completion of the Offer, Parent intends to conduct a detailed
review of the Company and its assets, corporate structure, dividend policy,
capitalization, operations, properties, policies, management and personnel and
consider what, if any, changes would be desirable in light of the circumstances
which then exist. Such changes could include changes in the Company's business,
corporate structure, charter, by-laws, capitalization, Board of Directors,
management or dividend policy, although, except as described in this Offer to
Purchase, Parent has no current plans with respect to any of such matters.
 
                                       23

<PAGE>

     Except as noted in this Offer to Purchase, neither Parent nor the Purchaser
has any present plans or proposals that would result in an extraordinary
corporate transaction, such as a merger, reorganization, liquidation, relocation

of operations, or sale or transfer of assets, involving the Company or any of
its subsidiaries, or any material changes in the Company's corporate structure,
business or composition of its management or personnel.
 
     13. DIVIDENDS AND DISTRIBUTIONS
 
     As described above, the Merger Agreement provides that, prior to the

Merger Agreement, (i) declare, set aside or pay any dividend on, or make any
other distributions in respect of, any of its capital stock, other than (A) as
contemplated by the Rights Agreement, (B) dividends paid by subsidiaries of the
Company to the Company with respect to capital stock, and (C) for regular
quarterly dividends not to exceed $.03 per quarter, (ii) split, combine or
reclassify any of its capital stock or issue or authorize the issuance of any
other securities in respect of, in lieu of or in substitution for shares of its
capital stock, or (iii) purchase, redeem or otherwise acquire any shares of
capital stock of the Company or any of its subsidiaries or any other securities
thereof or any rights, warrants or options to acquire any such shares or other
securities.
 
     14. CONDITIONS TO THE OFFER
 
     Notwithstanding any other provisions of the Offer, the Purchaser will not
be required to accept for payment or, subject to any applicable rules and
regulations of the SEC, including Rule 14e-1(c) promulgated under the Exchange
Act, pay for any tendered Shares and may terminate or, subject to the terms of
the Merger Agreement, amend the Offer, if (i) there shall not be validly
tendered and not properly withdrawn prior to the Expiration Date that number of
Shares which represents at least 90% of the total number of outstanding Shares
on the date of purchase (not taking into account the Rights), (ii) any
applicable waiting period under the HSR Act or under any applicable foreign
statutes or regulations shall not have expired or been terminated prior to the
Expiration Date, or (iii) at any time on or after the date of the Merger
Agreement and prior to the Expiration Date, any of the following events shall
occur:
 
          (a) an order shall have been entered in any action or proceeding
     before any United States federal or state court or governmental agency or
     other United States regulatory or administrative agency or commission (an
     'Order'), or a preliminary or permanent injunction by a United States court
     of competent jurisdiction shall have been issued and remain in effect (an
     'Injunction'), which, in either case, would have the effect of (i) making
     the purchase of, or payment for, some or all of the Shares pursuant to the
     Offer or Merger Agreement illegal, (ii) otherwise preventing consummation
     of the Offer or Merger, or (iii) imposing material limitations on the
     ability of the Purchaser or Holdings effectively to exercise full rights of
     ownership of the Shares, including the right to vote the Shares purchased
     by it on all matters properly presented to the shareholders of the Company;
     provided, however, that in order to invoke this condition, Parent and the
     Purchaser shall have used their best efforts to prevent such Order or
     Injunction or ameliorate the effects thereof; and provided, further, that,
     if the Order or Injunction is a temporary restraining order or preliminary
     injunction of a court of competent jurisdiction, the Purchaser may not, by
     virtue of this condition alone amend or terminate the Offer, but may only

     extend the Offer and thereby postpone acceptance for payment or purchase of
     Shares; or
 
          (b) there shall have been any United States or foreign federal or
     state statute, rule or regulation enacted or promulgated after the date of
     the Offer that would reasonably be expected to result in any of the
     material adverse consequences referred to in paragraph (a) above; or
 
          (c) there shall have occurred (i) any general suspension of, or
     limitation on prices for, trading in securities on the New York Stock
     Exchange, (ii) a declaration of a general banking moratorium or any
     suspension of payments in respect of banks in the United States, (iii) the
     commencement of a war, armed hostilities or other international or national
     calamity directly or indirectly involving the United States (other than in
     connection with actual or potential United States military activities in
     the Republic of Iraq as have been generally discussed in print and other
     news media during the four weeks preceding the date of the Merger
     Agreement), (iv) any limitation by any United States governmental entity on
     the extension of credit generally to banks and other financial
     institutions, or (v) in the case of any of the foregoing existing at the
     time of the commencement of the Offer, a material acceleration or worsening
     thereof; or
 
                                       24

<PAGE>

          (d) the Company shall have breached or failed to perform in any
     material respect any of its obligations, covenants or agreements contained
     in the Merger Agreement or any of the representations and warranties of the
     Company set forth in the Merger Agreement that are (i) qualified as to
     materiality or material adverse effect or (ii) with respect to the
     Company's capitalization and subsidiaries and the Company's authority to
     enter in the Merger Agreement and the transactions contemplated thereby
     shall not be true and correct or any such representations and warranties
     that are not so qualified as to materiality or material adverse effect
     shall not be true in any material respect, in each case as if made at such
     time; or
 
          (e) the Merger Agreement shall have been terminated in accordance with
     its terms; or
 
          (f) the Company's Board of Directors shall have publicly withdrawn or
     modified in any manner adverse to the Purchaser its recommendation that
     shareholders accept the Offer.
 
     The foregoing conditions (including those set forth in clauses (i) and (ii)
of the initial paragraph) are for the benefit of Holdings and the Purchaser and
may be asserted by Holdings or the Purchaser regardless of the circumstances
giving rise to any such conditions and, except for the Minimum Condition, which
may not be waived without the prior written consent of the Company, may be
waived by Holdings or the Purchaser, in whole or in part, at any time and from
time to time, in their reasonable discretion, in each case, subject to the terms
of the Merger Agreement. The failure by Holdings or the Purchaser at any time to

exercise any of the foregoing rights shall not be deemed a waiver of any such
right and each such right shall be deemed an ongoing right which may be asserted
at any time and from time to time.
 
     15. CERTAIN LEGAL MATTERS
 
     Except as described in this Section 15, based on a review of publicly
available filings by the Company with the SEC and other publicly available
information concerning the Company, the Purchaser is not aware of any regulatory
license or permit that appears to be material to the business of the Company and
its subsidiaries, taken as a whole, that might be adversely affected by the
acquisition of Shares by the Purchaser pursuant to the Offer or, except as set
forth below, of any approval or other action by any governmental, administrative
or regulatory agency or authority, domestic or foreign, that would be required
prior to the acquisition of Shares by the Purchaser pursuant to the Offer.
Should any such approval or other action be required, the Purchaser currently
contemplates that it will be sought. While the Purchaser does not currently
intend to delay the acceptance for payment of Shares tendered pursuant to the
Offer pending the outcome of any such matter, there can be no assurance that any
such approval or other action, if needed, would be obtained or would be obtained
without substantial conditions or that adverse consequences might not result to
the Company's business or that certain parts of the Company's business might not
have to be disposed of in the event that such approvals were not obtained or any
other actions were not taken. The Purchaser's obligation under the Offer to
accept for payment and pay for Shares is subject to certain conditions,
including conditions relating to the legal matters discussed in this Section 15.
See Section 14.
 
     State Takeover Statutes.  The GCL requires that holders of non-redeemable
common stock receive non-redeemable common stock in a merger of a corporation
with a holder (or such holder's affiliate) of more than 50% of the voting power
of such corporation but less than 90% of such outstanding shares of common
stock, unless all of the holders of such common stock consent to the transaction
or it is approved by the California Department of Corporations at a 'fairness
hearing' held with respect to such transactions. This provision of California
law may have the effect of making a 'cash-out' merger by a majority shareholder
more difficult to accomplish.
 
     The GCL also provides that, except in certain circumstances, when a tender
offer or a proposal for a reorganization (including certain mergers) or for a
sale of assets is made by an interested party (generally a controlling or
managing party of the target corporation), an affirmative opinion in writing as
to the fairness of the consideration to be paid to the shareholders of the
target must be delivered to such shareholders. Furthermore, if a tender of
shares or vote is sought pursuant to an interested party's proposal and another
party subsequently makes a proposal, the shareholders of the target company must
be informed of the later offer and be afforded a reasonable opportunity to
withdraw any vote, consent or proxy therefore given, or to withdraw any shares
tendered in response to the original interested party proposal, as the case may
be.
 
     In addition, the GCL provides that in any action to attack the validity of
a reorganization (including certain mergers) or to have such reorganization set
aside or rescinded, a party to such a reorganization which controls

 
                                       25
<PAGE>

another party to the reorganization shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and a person who controls two or more parties to a reorganization shall
have the burden of proving that the transaction is just and reasonable as to the
shareholders of any party so controlled.
 
     A number of other states have adopted 'takeover' statutes that purport to
apply to attempts to acquire corporations that are incorporated in such states,
or whose business operations have substantial economic effects in such states,
or which have substantial assets, security holders, employees, principal
executive offices or principal places of business in such states. In Edgar v.
MITE Corp., the Supreme Court of the United States, invalidated on
constitutional grounds the Illinois Business Takeover Statute, which, as a
matter of state securities law, made takeovers of corporation meeting certain
requirements more difficult. However, in 1997 CTS Corp. v. Dynamics Corp. of
America, the United States Supreme Court held that the State of Indiana
permissibly could, as a matter of corporate law and, in particular, with respect
to those aspects of corporate law relating to corporate governance,
constitutionally disqualify a potential acquiror from voting on the affairs of a
target corporation without the prior approval of the remaining shareholders. In
such case, the law before the Court was by its terms applicable only to
corporations that had a substantial number of shareholders in the state and were
incorporated there. The Company, directly or through subsidiaries, conducts
business in a number of states throughout the United States, some of which have
enacted 'takeover' statutes. The Purchaser does not know whether any of these
statutes will, by their terms, apply to the Offer, and has not complied with any
such statutes. To the extent that certain provisions of these statutes purport
to apply to the Offer, the Purchaser believes that there are reasonable bases
for contesting such statutes. If any person should seek to apply any state
takeover statute, the Purchaser would take such action as then appears
desirable, which action may include challenging the validity or applicability of
any such statute in appropriate court proceedings. If it is asserted that one or
more takeover statutes apply to the Offer, and it is not determined by an
appropriate court that such statute or statutes do not apply or are invalid as
applied to the Offer, the Purchaser might be required to file certain
information with, or receive approvals from, the relevant state authorities, and
the Purchaser might be unable to purchase or pay for Shares tendered pursuant to
the Offer, or be delayed in continuing or consummating the Offer. In such case,
the Purchaser may not be obligated to accept for payment or pay for Shares
tendered. See Section 14.
 
     United States Antitrust.  The Offer and the Merger are subject to the HSR
Act, which provides that certain acquisition transactions may not be consummated
unless certain information has been furnished to the Antitrust Division of the
Department of Justice (the 'Antitrust Division') and the Federal Trade
Commission ('FTC') and certain waiting period requirements have been satisfied.
Parent intends to promptly file a Notification and Report Form with respect to
the Offer and the Merger.
 
     Under the provisions of the HSR Act applicable to the Offer, the purchase

of Shares under the Offer may not be consummated until the expiration of a
15-calendar day waiting period following the filing by Parent, unless Parent
receives a request for additional information or documentary material, or the
Antitrust Division and the FTC terminate the waiting period prior thereto. If,
within such 15-day period, either the Antitrust Division or the FTC requests
additional information or material from Parent concerning the Offer, the waiting
period will be extended and would expire at 11:59 p.m., New York City time, on
the tenth calendar day after the date of substantial compliance by Parent with
such request. Only one extension of the waiting period pursuant to a request for
additional information is authorized by the HSR Act. Thereafter, such waiting
period may be extended only by court order or with the consent of Parent. The
Purchaser will not accept for payment Shares tendered pursuant to the Offer
unless and until the waiting period requirements imposed by the HSR Act with
respect to the Offer have been satisfied. See Section 14.
 
     The Merger would not require an additional filing under the HSR Act if the
Purchaser owns 50% or more of the outstanding Shares at the time of the Merger
or if the Merger occurs within one year after the HSR Act waiting period
applicable to the Offer expires or is terminated.
 
     German Antitrust.  German competition law requires the preclosing approval
of any merger or acquisition where (a) one party has consolidated worldwide net
sales in its most recent financial year exceeding 2 billion Deutsche marks
(approximately US$ 1.15 billion) or each of at least two parties to such
transaction has consolidated worldwide net sales exceeding 1 billion Deutsche
marks (approximately US$ 570 million), and (b) the transaction has effects in
Germany.
 
                                       26
<PAGE>

     The German Federal Cartel Office has an initial one-month review period in
which it may either (i) approve the Merger, or (ii) initiate a full
investigation to examine the consequences of the Merger. If a full investigation
is opened, it can last up to a total of no more than four months from the date
of the original notification. The parties are preparing the notification and do
not expect any delay in obtaining approval of the Merger within the initial
one-month review period.
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's acquisition of Shares
pursuant to the Offer and the Merger. At any time before or after the
Purchaser's acquisition of Shares, the Antitrust Division or the FTC could take
such action under the antitrust laws as it deems necessary or desirable in the
public interest, including seeking to enjoin the acquisition of Shares pursuant
to the Offer or otherwise or seeking divestiture of Shares acquired by the
Purchaser or divestiture of substantial assets of Parent or its subsidiaries.
Private parties and state attorneys general may also bring legal action under
the antitrust laws under certain circumstances. Based upon an examination of
publicly available information relating to the businesses in which Parent and
the Company are engaged, Parent and the Purchaser believe that the acquisition
of Shares by the Purchaser will not violate the antitrust laws. Nevertheless,
there can be no assurance that a challenge to the Offer or other acquisition of
Shares by the Purchaser on antitrust grounds will not be made or, if such a

challenge is made, of the result. See Section 14.
 
     16. FEES AND EXPENSES
 
     The Purchaser has retained Furman Selz LLC to act as the Dealer Manager,
D.F. King & Co., Inc. to act as the Information Agent and First Chicago Trust
Company of New York to act as the Depositary in connection with the Offer. The
Dealer Manager and the Information Agent may contact holders of Shares by mail,
telephone, telex, telegraph and personal interview and may request brokers,
dealers, commercial banks, trust companies and other nominees to forward the
Offer material to beneficial owners. The Dealer Manager, the Information Agent
and the Depositary each will receive reasonable and customary compensation for
their services, will be reimbursed for certain reasonable out-of-pocket expenses
and will be indemnified against certain liabilities and expenses in connection
therewith, including certain liabilities under the federal securities laws. None
of the Dealer Manager, the Information Agent or the Depositary has been retained
to make solicitations or recommendations in connection with the Offer. Neither
Parent nor the Purchaser will pay any fees or commissions to any broker or
dealer or other person (other than the Dealer Manager or the Information Agent)
for soliciting tenders of Shares pursuant to the Offer. Brokers, dealers,
commercial banks and trust companies will be reimbursed by the Purchaser for
reasonable expenses incurred by them in forwarding material to their customers.
 
     17. MISCELLANEOUS
 
     The Purchaser is not aware of any jurisdiction in which the making of the
Offer is not in compliance with applicable law. If the Purchaser becomes aware
of any jurisdiction in which the making of the Offer would not be in compliance
with applicable law, the Purchaser will make a good faith effort to comply with
any such law. If, after such good faith effort, the Purchaser cannot comply with
any such law, the Offer will not be made to (nor will tenders be accepted from
or on behalf of) the holders of Shares residing in such jurisdiction. In those
jurisdictions whose securities or blue sky laws require the Offer to be made by
a licensed broker or dealer, the Offer is being made on behalf of the Purchaser
by the Dealer Manager or by one or more registered brokers or dealers which are
licensed under the laws of such jurisdiction.
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF THE PURCHASER OR PARENT NOT CONTAINED IN THIS OFFER
TO PURCHASE OR IN THE LETTER OF TRANSMITTAL AND, IF GIVEN OR MADE, SUCH
INFORMATION OR REPRESENTATION MUST NOT BE RELIED UPON AS HAVING BEEN AUTHORIZED.
 
     The Purchaser has filed with the SEC the Schedule 14D-1 pursuant to Rule
14d-3 under the Exchange Act, furnishing certain additional information with
respect to the Offer, and may file amendments thereto. The Schedule 14D-1 and
any amendments thereto, including exhibits, may be inspected and copies may be
obtained at the same places and in the same manner as set forth under the
heading 'Available Information' in Section 8 (except that they will not be
available at the regional offices of the SEC).

                  CHAPTER 13 OF THE GENERAL CORPORATION LAW OF
                            THE STATE OF CALIFORNIA
                               DISSENTERS' RIGHTS
                         LEGISLATIVE COMMITTEE COMMENT
                                (1975)--ASSEMBLY
                                  [CORRECTED]
 
     Dissenters' rights are generally eliminated for shares having a highly
liquid public market (i.e., listed on the New York or American stock exchange or
included on the OTC margin stock list published by the Federal Reserve Board).
However, dissenters' rights will exist with respect to such shares if they are
subject to certain restrictions upon transfer or a substantial proportion (5%)
of the holders of a particular class of shares demand appraisal rights.
 
     If dissenters' rights exist due to these exceptions, the holder is
generally required to vote against the reorganization and demand payment in cash
for the fair market value of his shares not later than the shareholder meeting
at which the reorganization is approved. The new law also requires the
corporation to include in the notice of such meeting a statement of the possible
existence of a procedure for perfecting dissenters' rights.
 
     The fair market value of the shares is determined as of the day before the
first announcement of the terms of the proposed merger. If an appraisal action
is initiated in court by a dissenter and the appraised price exceeds 125% of the
fair market value of the shares as determined by the corporation, the
corporation may be required to pay all of the costs of the action, including
attorney's and other fees.
 
     The provisions regulating corporate repurchases of its own shares apply to
the purchase of dissenting shares is prevented thereunder, the holder of such
shares becomes a creditor of the corporation but subordinated to all other
creditors of the corporation.
 
SECTION 1300 REORGANIZATION OR SHORT-FORM MERGER; DISSENTING SHARES; CORPORATE
PURCHASE AT FAIR MARKET VALUE; DEFINITIONS
 
     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation in a short-form merger may, by complying with this chapter, require
the corporation in which the shareholder holds shares to purchase for cash at
their fair market value the shares owned by the shareholder which are dissenting
shares as defined in subdivision (b). The fair market value shall be determined
as of the day before the first announcement of the terms of the proposed
reorganization or short-form merger, excluding any appreciation or depreciation
in consequence of the proposed action, but adjusted for any stock split, reverse
stock split, or share dividend which becomes effective thereafter.
 
     (b) As used in this chapter, 'dissenting shares' means shares which come
within all of the following descriptions:

 
          (1) Which were not immediately prior to the reorganization or
     short-form merger either (A) listed on any national securities exchange
     certified by the Commissioner of Corporations under subdivision (o) of
     Section 25100 or (B) listed on the list of OTC margin stocks issued by the
     Board of Governors of the Federal Reserve System, and the notice of meeting
     of shareholders to act upon the reorganization summarizes this section and
     Sections 1301, 1302, 1303 and 1304; provided, however, that this provision
     does not apply to any shares with respect to which there exists any
     restriction on transfer imposed by the corporation or by any law or
     regulation; and provided, further, that this provision does not apply to
     any class of shares described in subparagraph (A) or (B) if demands for
     payment are filed with respect to 5 percent or more of the outstanding
     shares of that class.
 
                                      II-1

<PAGE>

          (2) Which were outstanding on that date for the termination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case
     where the approval required by Section 1201 is sought by written consent
     rather than at a meeting.
 
          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.
 
          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1302.
 
     (c) As used in this chapter,'dissenting shareholder' means the recordholder
of dissenting shares and includes a transferee of record.

SECTION 1301 NOTICE TO HOLDERS OF DISSENTING SHARES IN REORGANIZATIONS; DEMAND
FOR PURCHASE; TIME; CONTENTS
 
     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section l52)
within 10 days after the date of such approval, accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's right under such sections.

The statement of price constitutes an offer by the corporation to purchase at
the price stated any dissenting shares as defined in subdivision (b) of Section
1300, unless they lose their status as dissenting shares under Section 1309.
 
     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

shares described in the judgment. Any party may appeal from the judgment.
 
     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest

1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

SECTION 1312 RIGHT OF DISSENTING SHAREHOLDER TO ATTACK, SET ASIDE OR RESCIND
MERGER OR REORGANIZATION; RESTRAINING ORDER OR INJUNCTION; CONDITIONS
 
     (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attach the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.
 
     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attach the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon 10 days'
prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.
 
     (c) If one of the parties to a reorganization or short-form merger is

directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the
validity of the reorganization or short-form merger or to have the
reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

                 PLEASE READ THE INSTRUCTIONS SET FORTH IN THIS
                        LETTER OF TRANSMITTAL CAREFULLY.
 
Ladies and Gentlemen:
 
     The undersigned hereby tenders to ACC Acquisition Corp., a California
corporation (the "Purchaser") and an indirect wholly owned subsidiary of Danaher
Corporation, a Delaware corporation, the above-described shares of common stock,
par value $1.00 per share (the "Common Shares"), of Pacific Scientific Company,
a California corporation (the "Company"), including the associated preferred
share purchase rights (together with the Common Shares, the "Shares") issued
pursuant to the Rights Agreement, dated as of December 21, 1997, as amended as
of January 31, 1998, between the Company and ChaseMellon Shareholder Services,
L.L.C., as Rights Agent, pursuant to the Purchaser's offer to purchase all
outstanding Shares at $30.25 per Share, net to the seller in cash, upon the
terms and subject to the conditions set forth in the Offer to Purchase, dated
February 6, 1998 (the "Offer to Purchase"), receipt of which is hereby
acknowledged, and in this Letter of Transmittal (which, as amended or
supplemented from time to time, together constitute the "Offer"). The
undersigned understands that the Purchaser reserves the right to transfer or
assign, in whole or from time to time in part, to one or more of its affiliates,
the right to purchase all or any portion of the Shares tendered pursuant to the
Offer.
 
     Subject to, and effective upon, acceptance for payment of the Shares
tendered herewith, in accordance with the terms of the Offer (including, if the
Offer is extended or amended, the terms and conditions of such extension or
amendment), the undersigned hereby sells, assigns and transfers to, or upon the
order of, the Purchaser all right, title and interest in and to all the Shares
that are being tendered hereby and all dividends, distributions (including,
without limitation, distributions of additional Shares) and rights declared,
paid or distributed in respect of such Shares on or after January 31, 1998,
(collectively, "Distributions"), and irrevocably appoints the Depositary the
true and lawful agent and attorney-in-fact of the undersigned with respect to
such Shares and all Distributions, with full power of substitution (such power
of attorney being deemed to be an irrevocable power coupled with an interest),
to (i) deliver Share Certificates evidencing such Shares and all Distributions,
or transfer ownership of such Shares and all Distributions on the account books
maintained by the Book-Entry Transfer Facility, together, in either case, with
all accompanying evidences of transfer and authenticity, to or upon the order of
the Purchaser, (ii) present such Shares and all Distributions for transfer on

the books of the Company and (iii) receive all benefits and otherwise exercise
all rights of beneficial ownership of such Shares and all Distributions, all in
accordance with the terms of the Offer.
 
     The undersigned hereby irrevocably appoints Patrick W. Allender and C.
Scott Brannan, and each of them, as the attorneys and proxies of the
undersigned, each with full power of substitution, to vote in such manner as
each such attorney and proxy or his substitute shall, in his sole discretion,
deem proper and otherwise act (by written consent or otherwise) with respect to
all the Shares tendered hereby which have been accepted for payment by the
Purchaser prior to the time of such vote or other action and all Shares and
other securities issued in Distributions in respect of such Shares, which the
undersigned is entitled to vote at any meeting of shareholders of the Company
(whether annual or special and whether or not an adjourned or postponed meeting)
or consent in lieu of any such meeting or otherwise. This proxy and power of
attorney is coupled with an interest in the Shares tendered hereby, is
irrevocable and is granted in consideration of, and is effective upon, the
acceptance for payment of such Shares by the Purchaser in accordance with the
terms of the Offer. Such acceptance for payment shall revoke all other proxies
and powers of attorney granted by the undersigned at any time with respect to
such Shares (and all Shares and other securities issued in Distributions in
respect of such Shares), and no subsequent proxy or power of attorney shall be
given or written consent executed (and if given or executed, shall not be
effective) by the undersigned with respect thereto. The undersigned understands
that, in order for Shares to be deemed validly tendered, immediately upon the
Purchaser's acceptance of such Shares for payment, the Purchaser must be able to
exercise full voting and other rights with respect to such Shares, including,
without limitation, voting at any meeting of the Company's stockholders then
scheduled.
 
     The undersigned hereby represents and warrants that the undersigned has
full power and authority to tender, sell, assign and transfer the Shares
tendered hereby and all Distributions, and that when such Shares are accepted
for payment by the Purchaser, the Purchaser will acquire good, marketable and
unencumbered title thereto and to all Distributions, free and clear of all
liens, restrictions, charges and encumbrances, and that none of such Shares and
Distributions will be subject to any adverse claim. The undersigned, upon
request, shall execute and deliver all additional documents deemed by the
Depositary or the Purchaser to be necessary or desirable to complete the sale,
assignment and transfer of the Shares tendered hereby and all Distributions. In
addition, the undersigned shall remit and transfer promptly to the Depositary
for the account of the Purchaser all Distributions in respect of the Shares
tendered hereby, accompanied by appropriate documentation of transfer, and,
pending such remittance and transfer or appropriate assurance thereof, the
Purchaser shall be entitled to all rights and privileges as owner of each such
Distribution and may withhold the entire purchase price of the Shares tendered
hereby or deduct from such purchase price the amount or value of such
Distribution as determined by the Purchaser in its sole discretion.

<PAGE>

     No authority herein conferred or agreed to be conferred shall be affected
by, and all such authority shall survive, the death or incapacity of the
undersigned. All obligations of the undersigned hereunder shall be binding upon

the heirs, personal representatives, successors and assigns of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.
 
     The undersigned understands that tenders of Shares pursuant to any one of
the procedures described in Section 3 of the Offer to Purchase and in the
instructions hereto will constitute the undersigned's acceptance of the terms
and conditions of the Offer. The Purchaser's acceptance of such Shares for
payment will constitute a binding agreement between the undersigned and the
Purchaser upon the terms and subject to the conditions of the Offer.
 
     Unless otherwise indicated herein in the box entitled "Special Payment
Instructions," please issue the check for the purchase price of all Shares
purchased, and return all Share Certificates evidencing Shares not purchased or
not tendered, in the name(s) of the registered holder(s) appearing above under

"Special Payment Instructions" and "Special Delivery Instructions" are both
completed, please issue the check for the purchase price of all Shares purchased
and return all Share Certificates evidencing Shares not purchased or not
tendered in the name(s) of, and mail such check and Share Certificates to, the

obligation, pursuant to the Special Payment Instructions, to transfer any Shares
from the name of the registered holder(s) thereof if the Purchaser does not
purchase any of the Shares tendered hereby.

                                  INSTRUCTIONS
             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.  Guarantee of Signatures. Except as otherwise provided below, all
signatures on this Letter of Transmittal must be guaranteed by a financial
institution (including most banks, savings and loan associations and brokerage
houses) that is a participant in the Security Transfer Agents Medallion Program
(each an "Eligible Institution"). No signature guarantee is required on this
Letter of Transmittal (a) if this Letter of Transmittal is signed by the
registered holder(s) (which term, for purposes of this document, shall include
any participant in the Book-Entry Transfer Facility whose name appears on a
security position listing as the owner of Shares) of Shares tendered herewith,
unless such holder(s) has completed either the box entitled "Special Delivery
Instructions" or the box entitled "Special Payment Instructions" on the reverse
hereof, or (b) if such Shares are tendered for the account of an Eligible
Institution. See Instruction 5.
 
    2.  Delivery of Letter of Transmittal and Share Certificates. This Letter of
Transmittal is to be used if either Share Certificates are to be forwarded
herewith or if Shares are to be delivered by book-entry transfer pursuant to the
procedure set forth in Section 3 of the Offer to Purchase. Share Certificates
evidencing all physically tendered Shares, or a confirmation of a book-entry
transfer into the Depositary's account at the Book-Entry Transfer Facility of
all Shares delivered by book-entry transfer as well as a properly completed and
duly executed Letter of Transmittal (or facsimile thereof) with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message, as defined below) and any other documents required by this Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth on the reverse hereof prior to the Expiration Date (as defined in Section
l of the Offer to Purchase). If Share Certificates are forwarded to the
Depositary in multiple deliveries, a properly completed and duly executed Letter
of Transmittal must accompany each such delivery. Shareholders whose Share
Certificates are not immediately available, who cannot deliver their Share
Certificates and all other required documents to the Depositary prior to the
Expiration Date or who cannot complete the procedure for delivery by book-entry
transfer on a timely basis may tender their Shares pursuant to the guaranteed
delivery procedure described in Section 3 of the Offer to Purchase. Pursuant to
such procedure: (i) such tender must be made by or through an Eligible
Institution; (ii) a properly completed and duly executed Notice of Guaranteed

Delivery, substantially in the form made available by the Purchaser, must be
received by the Depositary prior to the Expiration Date; and (iii) the Share
Certificates evidencing all physically delivered Shares in proper form for
transfer by delivery, or a confirmation of a book-entry transfer into the
Depositary's account at the Book-Entry Transfer Facility of all Shares delivered
by book-entry transfer, in each case together with a Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, with any required
signature guarantees (or, in the case of a book-entry transfer, an Agent's
Message), and any other documents required by this Letter of Transmittal, must
be received by the Depositary within three New York Stock Exchange trading days
after the date of execution of such Notice of Guaranteed Delivery, all as
described in Section 3 of the Offer to Purchase. The term "Agent's Message"
means a message, transmitted by the Book-Entry Transfer Facility to, and
received by, the Depositary and forming a part of the Book-Entry Confirmation,
which states that the Book-Entry Transfer Facility has received an express
acknowledgment from the participant in the Book-Entry Transfer Facility
tendering the Shares that such participant has received and agrees to be bound
by the terms of this Letter of Transmittal and that the Purchaser may enforce
such agreement against the participant.
 
    THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES AND
ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING SHAREHOLDER, AND THE
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY. IF
DELIVERY IS BY MAIL, REGISTERED MAIL WITH RETURN RECEIPT REQUESTED, PROPERLY
INSURED, IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED TO
ENSURE TIMELY DELIVERY.
 
    No alternative, conditional or contingent tenders will be accepted and no
fractional Shares will be purchased. By execution of this Letter of Transmittal
(or a facsimile hereof), all tendering shareholders waive any right to receive
any notice of the acceptance of their Shares for payment.
 
    3.  Inadequate Space. If the space provided herein under "Description of
Shares Tendered" is inadequate, the Share Certificate numbers, the number of
Shares evidenced by such Share Certificates and the number of Shares tendered
should be listed on a separate schedule and attached hereto.
 
    4.  Partial Tenders (not applicable to shareholders who tender by book-entry
transfer). If fewer than all the Shares evidenced by any Share Certificate
delivered to the Depositary herewith are to be tendered hereby, fill in the
number of Shares which are to be tendered in the box entitled "Number of Shares
Tendered." In such cases, new Share Certificate(s) evidencing the remainder of
the Shares that were evidenced by the Share Certificates delivered to the
Depositary herewith will be sent to the person(s) signing this Letter of
Transmittal, unless otherwise provided in the box entitled "Special Delivery
Instructions" on the reverse hereof, as soon as practicable after the expiration
or termination of the Offer. All Shares evidenced by Share Certificates
delivered to the Depositary will be deemed to have been tendered unless
otherwise indicated.
 
    5.  Signatures on Letter of Transmittal; Stock Powers and Endorsements. If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on

the face of the Share Certificates evidencing such Shares without alteration,
enlargement or any other change whatsoever. If any Share tendered hereby is
owned of record by two or more persons, all such persons must sign this Letter
of Transmittal.

<PAGE>

    If any of the Shares tendered hereby are registered in the names of
different holders, it will be necessary to complete, sign and submit as many
separate Letters of Transmittal as there are different registrations of such
Shares.
 
    If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of Share Certificates or separate stock
powers are required, unless payment is to be made to, or Share Certificates
evidencing Shares not tendered or not purchased are to be issued in the name of,
a person other than the registered holder(s), in which case the Share
Certificate(s) evidencing the Shares tendered hereby must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the registered holder(s) appear(s) on such Share Certificate(s).
Signatures on such Share Certificate(s) and stock powers must be guaranteed by
an Eligible Institution.
 
    If this Letter of Transmittal is signed by a person other than the
registered holder(s) of the Shares tendered hereby, the Share Certificate(s)
evidencing the Shares tendered hereby must be endorsed or accompanied by
appropriate stock powers, in either case signed exactly as the name(s) of the
registered holder(s) appear(s) on such Share Certificate(s). Signatures on such
Share Certificate(s) and stock powers must be guaranteed by an Eligible
Institution.
 
    If this Letter of Transmittal or any Share Certificate or stock power is
signed by a trustee, executor, administrator, guardian, attorney-in-fact,
officer of a corporation or other person acting in a fiduciary or representative
capacity, such person should so indicate when signing, and proper evidence
satisfactory to the Purchaser of such person's authority so to act must be
submitted.
 
    6.  Stock Transfer Taxes. Except as otherwise provided in this Instruction
6, the Purchaser will pay all stock transfer taxes with respect to the sale and
transfer of any Shares to it or its order pursuant to the Offer. If, however,
payment of the purchase price of any Shares purchased is to be made to, or Share
Certificate(s) evidencing Shares not tendered or not purchased are to be issued
in the name of, a person other than the registered holder(s), the amount of any
stock transfer taxes (whether imposed on the registered holder(s), such other

check or any such Share Certificate is to be sent to someone other than the
person(s) signing this Letter of Transmittal or to the person(s) signing this

    9.  Substitute Form W-9. Each tendering shareholder is required to provide
the Depositary with a correct Taxpayer Identification Number ("TIN") on the
Substitute Form W-9 which is provided under "Important Tax Information" below,
and to certify, under penalties of perjury, that such number is correct and that
such shareholder is not subject to backup withholding of federal income tax. If
a tendering shareholder has been notified by the Internal Revenue Service that
such shareholder is subject to backup withholding, such shareholder must cross
out item (2) of the Certification box of the Substitute Form W-9, unless such
shareholder has since been notified by the Internal Revenue Service that such
shareholder is no longer subject to backup withholding. Failure to provide the
information on the Substitute Form W-9 may subject the tendering shareholder to
31% federal income tax withholding on the payment of the purchase price of all
Shares purchased from such shareholder. If the tendering shareholder has not
been issued a TIN and has applied for one or intends to apply for one in the
near future, such shareholder should write "Applied For" in the space provided
for the TIN in Part I of the Substitute Form W-9, sign and date the Substitute
Form W-9 and complete the Certificate of Awaiting Taxpayer Identification Number
below. Notwithstanding that "Applied For" is written in Part I and the
Certificate of Awaiting Taxpayer Identification Number is completed, the
Depositary will withhold 31% of all payments of the purchase price to such
shareholder until a TIN is provided to the Depositary. Such amounts will be
refunded to such shareholder if a TIN is provided to the Depositary within 60
days.
 
    10.  Lost, Destroyed or Stolen Certificates. If any certificate(s)
representing Shares has been lost, destroyed or stolen, the tendering
shareholder should promptly notify the Depositary. The tendering shareholder
will then be instructed as to the steps that must be taken in order to replace
the certificate(s). This Letter of Transmittal and related documents cannot be
processed until the procedures for replacing lost or destroyed certificates have
been followed.
 
    IMPORTANT: THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), PROPERLY
COMPLETED AND DULY EXECUTED (TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES AND
SHARE CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND ALL OTHER REQUIRED
DOCUMENTS) OR A PROPERLY COMPLETED AND DULY EXECUTED NOTICE OF GUARANTEED
DELIVERY MUST BE RECEIVED BY THE DEPOSITARY PRIOR TO THE EXPIRATION DATE (AS
DEFINED IN THE OFFER TO PURCHASE).


<PAGE>

                           IMPORTANT TAX INFORMATION
 
    Under the federal income tax law, a shareholder whose tendered Shares are
accepted for payment is required by law to provide the Depositary (as payer)
with such shareholder's correct TIN on Substitute Form W-9 below. If such
shareholder is an individual, the TIN is such shareholder's social security
number. If the Depositary is not provided with the correct TIN, the shareholder
may be subject to a $50 penalty imposed by the Internal Revenue Service. In
addition, payments that are made to such shareholder with respect to Shares
purchased pursuant to the Offer may be subject to backup withholding at a rate
of 31%.
 
    Certain shareholders (including, among others, all corporations and certain
foreign individuals) are not subject to these backup withholding and reporting
requirements. In order for a foreign individual to qualify as an exempt
recipient, such individual must submit a statement, signed under penalties of
perjury, attesting to such individual's exempt status. Forms of such statements
can be obtained from the Depositary. See the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the shareholder. Backup withholding is not an additional
tax. Rather, the tax liability of persons subject to backup withholding will be
reduced by the amount of tax withheld. If withholding results in an overpayment
of taxes, a refund may be obtained from the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup withholding on payments that are made to a shareholder
with respect to Shares purchased pursuant to the Offer, the shareholder is
required to notify the Depositary of such shareholder's correct TIN by
completing the form below certifying (a) that the TIN provided on Substitute
Form W-9 is correct (or that such shareholder is awaiting a TIN), and (b) that
such shareholder is not subject to backup withholding because (i) such
shareholder has not been notified by the Internal Revenue Service that such
shareholder is subject to backup withholding as a result of a failure to report
all interest or dividends, (ii) the Internal Revenue Service has notified such
shareholder that such shareholder is no longer subject to backup withholding or
(iii) such shareholder is exempt from backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
    The shareholder is required to give the Depositary the social security
number or employer identification number of the record holder of the Shares
tendered hereby. If the Shares are in more than one name or are not in the name
of the actual owner, consult the enclosed Guidelines for Certification of
Taxpayer Identification Number on Substitute Form W-9 for additional guidance on
which number to report. If the tendering shareholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, the shareholder should write "Applied For" in the space provided for the
TIN in Part I, sign and date the Substitute Form W-9 and complete the

Certificate of Awaiting Taxpayer Identification Number below. Notwithstanding
that "Applied For" is written in Part I and the Certificate of Awaiting Taxpayer
Identification Number is completed, the Depositary will withhold 31% of all
payments of the purchase price to such shareholder until a TIN is provided to
the Depositary. Such amounts will be refunded to such shareholder if a TIN is
provided to the Depositary within 60 days.

     31% of all reportable payments made to me thereafter will be withheld

 being notified by the IRS that you were subject to backup withholding you 
 received another notification from the IRS that you are no longer subject to 
 backup withholding, do not cross out item (2). (Also see instructions in the

as of January 31, 1998 (the "Merger Agreement"), by and among the Company, DH
Holdings Corp., a Delaware corporation ("Holdings") and a direct wholly owned
subsidiary of Parent, and the Purchaser. The Merger Agreement provides, among

of the Merger, each outstanding Share (other than Shares held in the treasury of
the Company or by any wholly owned subsidiary of the Company and Shares owned by
Holdings, the Purchaser or any other wholly owned subsidiary of Holdings or the
Purchaser or held by shareholders, if any, who are entitled to and who properly
exercise dissenters' rights under California law) will be converted into the
right to receive an amount in cash equal to the Offer Price.
 
     In all cases, payment for Shares tendered and accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of the

connection with a book-entry transfer, and any other documents required by the
Letter of Transmittal.
 
     If a holder of Shares wishes to tender Shares, but cannot deliver such
holder's certificates or other required documents, or cannot comply with the
procedure for book-entry transfer, prior to the expiration of the Offer, a
tender of Shares may be effected by following the guaranteed delivery procedure
described in Section 3 of the Offer to Purchase.
 
     The Purchaser will not pay any fees or commissions to any broker, dealer or
other person (other than the Dealer Manager or the Information Agent as
described in the Offer) in connection with the solicitation of tenders of Shares
pursuant to the Offer. However, the Purchaser will reimburse you for customary
mailing and handling expenses incurred by you in forwarding any of the enclosed

cause and not to willful neglect.

 
(2)  FAILURE TO REPORT CERTAIN DIVIDEND AND INTEREST PAYMENTS.--If you fail to
include any portion of an includible payment for interest, dividends, or
patronage dividends in gross income, such failure will be treated as being due
to negligence and will be subject to a penalty of 5% on any portion of an
under-payment attributable to that failure unless there is clear and convincing
evidence to the contrary.
 
(3)  CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
 
(4)  CRIMINAL PENALTY FOR FALSIFYING INFORMATION.-- Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
 
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

This announcement is neither an offer to purchase nor a solicitation of an offer
to sell Shares. The Offer is made solely by the Offer to Purchase dated February
 6, 1998 and the related Letter of Transmittal and is being made to all holders
of Shares. The Offer is not being made to (nor will tenders be accepted from or
 on behalf of) holders of Shares in any jurisdiction in which the making of the
Offer or the acceptance thereof would not be in compliance with the securities,
blue sky or other laws of such jurisdiction. However, the Purchaser may, in its
 discretion, take such action as it may deem necessary to make the Offer in any
jurisdiction and extend the Offer to holders of Shares in such jurisdiction. In
 those jurisdictions where securities, blue sky or other laws require the Offer
to be made by a licensed broker or dealer, the Offer shall be deemed to be made
on behalf of the Purchaser by Furman Selz LLC or one or more registered brokers
            or dealers licensed under the laws of such jurisdiction.

                      Notice of Offer to Purchase for Cash

                     All Outstanding Shares of Common Stock

           (Including the associated Preferred Share Purchase Rights)

                                       of

                           Pacific Scientific Company

                                       at

                              $30.25 Net Per Share

                                       by

                             ACC Acquisition Corp.

                     an indirect wholly owned subsidiary of

                              Danaher Corporation

                    ACC Acquisition Corp., a California corporation (the
     "Purchaser") and an indirect wholly owned subsidiary of Danaher
     Corporation, a Delaware corporation ("Danaher"), is offering to purchase
     all outstanding shares of common stock, par value $1.00 per share (the
     "Common Shares"), of Pacific Scientific Company, a California corporation
     (the "Company"), including the associated preferred share purchase rights
     (together with the Common Shares, the "Shares") issued pursuant to the
     Rights Agreement, dated as of December 31, 1997, as amended as of January
     31, 1998, between the Company and ChaseMellon Shareholder Services, L.L.C.,
     as Rights Agent, at $30.25 per Share, net to the seller in cash, without
     interest thereon (the "Offer Price"), upon the terms and subject to the
     conditions set forth in the Offer to Purchase, dated February 6, 1998 (the
     "Offer to Purchase"), and in the related Letter of Transmittal (which, as
     amended or supplemented from time to time, together constitute the
     "Offer"). Following the Offer, the Purchaser intends to effect the Merger
     described below.


     THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK
       CITY TIME, ON FRIDAY, MARCH 6, 1998, UNLESS THE OFFER IS EXTENDED.

                    THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE
     BEING VALIDLY TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE
     OFFER THAT NUMBER OF SHARES WHICH REPRESENTS AT LEAST 90% OF THE SHARES
     OUTSTANDING ON THE DATE OF PURCHASE ("THE MINIMUM CONDITION"). THE OFFER IS
     ALSO SUBJECT TO OTHER TERMS AND CONDITIONS.

                    The Offer is being made pursuant to an Agreement and Plan of
     Merger, dated as of January 31, 1998 (the "Merger Agreement"), by and among
     the Company, DH Holdings Corp., a Delaware corporation and a direct wholly
     owned subsidiary of Danaher ("Holdings"), and the Purchaser. The Merger
     Agreement provides, among other things, that following the consummation of
     the Offer and the satisfaction or waiver of the other conditions set forth
     in the Merger Agreement, the Purchaser will be merged with and into the
     Company (the "Merger"), with the Company continuing as the surviving
     corporation. At the effective time of the Merger, each outstanding Share
     (other than Shares held in the treasury of the Company or by any wholly
     owned subsidiary of the Company and Shares owned by Holdings, the Purchaser
     or any other wholly owned subsidiary of Holdings or the Purchaser or held
     by shareholders, if any, who are entitled to and who properly exercise
     dissenters' rights under California law) will be converted into the right
     to receive an amount in cash equal to the Offer Price, without interest.

                    As indicated above, the Merger Agreement contemplates a
     two-step transaction in which, following consummation of the Offer, the
     Merger occurs. Under California law, if the Purchaser acquires, pursuant to
     the Offer or otherwise, at least 90% of the then outstanding Shares, the
     Purchaser will be able to approve and adopt the Merger Agreement and the
     transactions contemplated thereby, including the Merger, without a vote of
     the Company's shareholders. In such event, Holdings, the Purchaser and the
     Company have agreed to take, at the request of the Purchaser, all necessary
     and appropriate action to cause the Merger to become effective as soon as
     practicable after such acquisition, without a meeting of the Company's
     shareholders, in accordance with the General Corporation Law of the State
     of California. However, under California law, the Merger may not be
     accomplished for cash paid to the remaining Company shareholders if the
     Purchaser, Holdings or Parent owns directly or indirectly more than 50% but
     less than 90% of the then outstanding Shares unless either all of the
     remaining shareholders of the Company consent to the Merger or the
     Commissioner of Corporations of the State of California approves, after a
     hearing, the terms and conditions of the Merger and the fairness thereof.
     Accordingly, Parent and the Company intend to proceed simultaneously with
     an alternative to this two-step transaction in which the Company pursues a
     one-step cash merger at the Offer Price. This one-step transaction would
     require the affirmative vote of a majority of the Company's outstanding
     voting stock. In the event the Minimum Condition is not fulfilled, the
     Merger Agreement contemplates that the Offer will be terminated and Parent
     and the Company will seek to implement the one-step cash merger
     transaction. In furtherance of the foregoing, if on the scheduled
     Expiration Date (or any extension thereof) all of the conditions to the
     Offer other than the Minimum Condition are satisfied but less than 90% of

     the outstanding Shares have been validly tendered and not withdrawn in the
     Offer, the Purchaser has agreed to extend the Offer for one additional
     business day (or such longer time as may be agreed to by the Purchaser and
     the Company), and to effect additional extensions as necessary until the
     earlier of (i) the close of business on the business day immediately prior
     to the Special Meeting of the Company's shareholders to be called to
     approve the Merger or (ii) such time as the Minimum Condition has been
     satisfied.

                    THE BOARD OF DIRECTORS OF THE COMPANY HAS APPROVED THE OFFER
     AND THE MERGER, HAS DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER
     ARE FAIR TO AND IN THE BEST INTERESTS OF THE SHAREHOLDERS OF THE COMPANY
     AND RECOMMENDS THAT SHAREHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES
     PURSUANT TO THE OFFER.

                    For purposes of the Offer, the Purchaser will be deemed to
     have accepted for payment, and thereby purchased, tendered Shares if, as
     and when the Purchaser gives oral or written notice to First Chicago Trust
     Company of New York (the "Depositary") of the Purchaser's acceptance of
     such Shares for payment. Payment for Shares accepted pursuant to the Offer
     will be made by deposit of the purchase price with the Depositary, which
     will act as agent for tendering shareholders for the purpose of receiving
     payments from the Purchaser and transmitting payments to such tendering
     shareholders. Under no circumstance will interest on the purchase price for
     Shares be paid by the Purchaser, regardless of any delay in making such
     payment. In all cases, payment for Shares tendered and accepted for payment
     pursuant to the Offer will be made only after timely receipt by the
     Depositary of (i) the certificates evidencing such Shares (the "Share
     Certificates") or timely confirmation of a book-entry transfer of such
     Shares into the Depositary's account at the Book-Entry Transfer Facility
     (as defined in Section 2 of the Offer to Purchase) pursuant to the
     procedures set forth in Section 2 of the Offer to Purchase, (ii) the Letter
     of Transmittal (or a facsimile thereof), properly completed and duly
     executed, with any required signature guarantees or an Agent's Message (as
     defined in Section 2 of the Offer to Purchase) in connection with a
     book-entry transfer, and (iii) any other documents required by the Letter
     of Transmittal.

                    Tenders of Shares made pursuant to the Offer are irrevocable
     except that such Shares may be withdrawn at any time prior to 12:00
     midnight, New York City time, on Friday, March 6, 1998 (or the latest time
     and date at which the Offer, if extended by the Purchaser, shall expire)

     the Offer, may also be withdrawn at any time after April 6, 1998, or at

     withdrawal must specify the name of the person who tendered the Shares to
     be withdrawn, the number of Shares to be withdrawn and the name of the
     registered holder, if different from that of the person who tendered such
     Shares. If Share Certificates evidencing Shares to be withdrawn have been
     delivered or otherwise identified to the Depositary, then, prior to the
     physical release of such Share Certificates, the serial numbers of the

     particular Share Certificates and a signed notice of withdrawal with
     signatures guaranteed by an Eligible Institution (as defined in Section 2
     of the Offer to Purchase), except in the case of Shares tendered for the
     account of an Eligible Institution, must also be furnished to the
     Depositary. If Shares have been tendered pursuant to the procedure for
     book-entry transfer as set forth in Section 3 of the Offer to Purchase, any
     notice of withdrawal must also specify the name and number of the account
     at the Book-Entry Transfer Facility to be credited with the withdrawn
     Shares. All questions as to the form and validity (including time of
     receipt) of notices of withdrawal will be determined by the Purchaser, in
     its sole discretion, whose determination will be final and binding.

                    The information required to be disclosed by Rule
     14d-6(e)(1)(vii) of the General Rules and Regulations under the Securities
     Exchange Act of 1934, as amended, is contained in the Offer to Purchase and

     for subsequent transmittal to beneficial owners of Shares.

                DANAHER CORPORATION TO ACQUIRE PACIFIC SCIENTIFIC
                          FOR $30.25 PER SHARE IN CASH

Washington D.C. and Newport Beach, CA, February 2, 1998 - Danaher Corporation
(NYSE:DHR) and Pacific Scientific Company (NYSE:PSX) announced today that
Danaher will acquire Pacific Scientific in an all-cash transaction in which
Pacific Scientific shareholders will receive $30.25 per share. The transaction
has a total value, including the Pacific Scientific debt to be assumed by
Danaher, of approximately $460 million. Pursuant to the terms of the definitive
merger agreement, a subsidiary of Danaher intends to promptly commence a cash
tender offer for Pacific Scientific stock. Any shares not purchased in the
tender offer will be acquired in a merger for $30.25 per share in cash.

The directors of Pacific Scientific have unanimously approved the Danaher
transaction and recommend that Pacific Scientific shareholders accept the
Danaher offer and tender their shares.

"We are pleased with the combination of Danaher and Pacific Scientific," George
M. Sherman, President and Chief Executive Officer of Danaher Corporation, said.
"The businesses Danaher will be acquiring represent attractive strategic
opportunities for our process/environmental controls segment."

Lester Hill, Chairman and Chief Executive Officer of Pacific Scientific, said,
"I'm very excited that our board and management have fulfilled their promise to
deliver full value for shareholders. The global strength of Danaher will allow
worldwide customers to enjoy the premium performance of Pacific Scientific
products while accelerating our improvement process to enhance quality,
manufacturing efficiency, and superior customer service."

The completion of the transaction is subject to customary conditions, including
Hart-Scott-Rodino regulatory approval. The purchase of shares in the tender

offer is subject to, among other things, the valid tender of Pacific Scientific
stock representing at least 90% of the outstanding shares. If this condition is
met, the tender offer will be completed and Pacific Scientific will be merged
with a wholly owned subsidiary of Danaher, and all Pacific Scientific
shareholders, including those who have not tendered their shares, will receive
$30.25 per share in cash. Pacific Scientific also expects to schedule a special
meeting of its shareholders to vote upon the proposed acquisition by Danaher. In
the event the minimum condition of the tender offer is not satisfied prior to
the special meeting, the transaction may otherwise be approved by a vote of a
simple majority of the Pacific Scientific shares outstanding at the special
meeting. If so approved, Pacific Scientific would be merged with a wholly owned
subsidiary of Danaher, and all Pacific Scientific shareholders would receive
$30.25 per share in cash.

BancAmerica Robertson Stephens, Pacific Scientific's financial advisor, has
delivered to Pacific Scientific's directors its opinion that the consideration
to be received by Pacific Scientific's common shareholders in the Danaher tender
offer and merger is fair to shareholders from a financial point of view. The
full text of BancAmerica Robertson Stephens' fairness opinion will be included
in Pacific Scientific's Schedule 14-D9 and Pacific Scientific shareholders are
referred thereto.

Pacific Scientific Company is an international business that designs,
manufactures and markets motion control, process control and safety equipment.

Danaher is a leading manufacturer of Tools and Components, and
Process/Environmental Controls.
