To the Holders of Common Stock of
  IMO INDUSTRIES INC.:
 
                                  INTRODUCTION
 
     UD Delaware Corp., a Delaware corporation ("Purchaser") and an indirect
wholly owned subsidiary of United Dominion Industries Limited, a corporation
organized under the laws of Canada ("Parent"), hereby offers to purchase all
outstanding shares of Common Stock, par value $1.00 per share (the "Common
Stock"), of Imo Industries Inc., a Delaware corporation (the "Company"), and
each associated right to purchase shares of the Company's Series B Junior
Participating Preferred Stock (individually, a "Right" and collectively, the
"Rights") issued pursuant to the Rights Agreement dated as of April 30, 1997, as
amended, between the Company and First Chicago Trust Company of New York (the
"Rights Agreement") (such shares of Common Stock and the Rights collectively
referred to as the "Shares"), at a price of $6.00 per Share, net to the seller
in cash, without interest thereon, 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 from time to time, together constitute the "Offer").
 
     Tendering stockholders will not be obligated to pay brokerage fees or
commissions or, except as otherwise provided in Instruction 6 of the Letter of
Transmittal, stock transfer taxes with respect to the purchase of Shares by
Purchaser pursuant to the Offer. Purchaser will pay all charges and expenses of
Goldman, Sachs & Co. ("Goldman Sachs") and Union Bancaire Privee International,
Inc. ("Union Bancaire"), who are acting as Dealer Managers for the Offer (in
such capacities, collectively, the "Dealer Managers"), First Chicago Trust
Company of New York (the "Depositary") and MacKenzie Partners, Inc. (the
"Information Agent") incurred in connection with the Offer. See Section 16.
 
     THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
DETERMINED THAT EACH OF THE OFFER AND THE MERGER (AS DEFINED BELOW) IS FAIR TO
AND IN THE BEST INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS, AND RECOMMENDS
THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE
OFFER.
 
     Credit Suisse First Boston Corporation ("Credit Suisse First Boston"), the
Company's financial advisor, has delivered to the Company's Board of Directors
its written opinion that, as of the date of such opinion, the consideration to
be received by the holders of Shares pursuant to each of the Offer and the
Merger is fair to such holders of Shares from a financial point of view. A copy
of the opinion of Credit Suisse First Boston is contained in the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9"),
which is being mailed to stockholders herewith.
 
     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST THE
NUMBER OF SHARES THAT SHALL CONSTITUTE MORE THAN EIGHTY PERCENT (80%) OF THE
SHARES THEN OUTSTANDING (THE "MINIMUM CONDITION"), (II) THE RECEIPT OF CONSENTS
FROM THE HOLDERS OF A MAJORITY OF THE THEN OUTSTANDING PRINCIPAL AMOUNT OF THE
11 3/4% SENIOR SUBORDINATED NOTES DUE MAY 1, 2006 OF THE COMPANY (THE "NOTES")
TO AMEND CERTAIN PROVISIONS OF THE INDENTURE GOVERNING THE NOTES SO THAT SUCH
PROVISIONS ARE NOT APPLICABLE TO THE MERGER OR FOLLOWING CONSUMMATION OF THE
MERGER OR SUCH OFFER FOR THE NOTES, AND (III) THE EXPIRATION OR TERMINATION OF
ANY APPLICABLE ANTITRUST WAITING PERIODS. SEE SECTION 14, WHICH SETS FORTH IN
FULL THE CONDITIONS TO THE OFFER.
 
     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of June 26, 1997 (the "Merger Agreement"), among Parent, Purchaser and the
Company. The Merger Agreement provides that, among other things, as soon as
practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement and in
accordance
<PAGE>   4
 
with the relevant provisions of the General Corporation Law of the State of
Delaware ("Delaware Law"), Purchaser will be merged with and into the Company
(the "Merger"). Following consummation of the Merger, the Company will continue
as the surviving corporation (the "Surviving Corporation") as an indirect wholly
owned subsidiary of Parent. At the effective time of the Merger (the "Effective
Time"), each Share (including the associated Right) issued and outstanding
immediately prior to the Effective Time (other than Shares owned by Purchaser,
Parent, the Company or any wholly owned subsidiary of Parent or of the Company
and any Shares that are held by stockholders who have properly exercised their
rights for appraisal of such Shares in accordance with Delaware Law) will be
cancelled and converted automatically into the right to receive $6.00 in cash,
or any higher price that may be paid per Share in the Offer, without interest
(the "Merger Consideration"). The Merger Agreement is more fully described in
Section 10.
 
     The Merger Agreement provides that, promptly upon the purchase by Purchaser
of Shares pursuant to the Offer and from time to time thereafter, Purchaser
shall be entitled to designate up to such number of directors, rounded up to the
next whole number, on the Board as will give Purchaser representation on the
Board equal to the product of the number of the total directors on the Board
(giving effect to the directors to be elected as described in this sentence)
multiplied by the percentage that the aggregate number of Shares then
beneficially owned by Purchaser and its affiliates following such purchase bears
to the total number of Shares then outstanding. In the Merger Agreement, the
Company has agreed to take all actions necessary to cause Purchaser's designees
to be elected as directors of the Company, including increasing the size of the
Board or securing the resignations of incumbent directors or both.
 
     The consummation of the Merger is subject to the satisfaction or waiver of
certain conditions, including, if required by Delaware Law, the approval and
adoption of the Merger Agreement by the requisite vote of the stockholders of
the Company. See Section 10. Under the Company's Certificate of Incorporation
and Delaware Law, the affirmative vote of the holders of a majority of the
outstanding Shares entitled to vote thereon is required to approve and adopt the
Merger Agreement and the Merger, provided, that if Purchaser purchases 90
percent of the Shares then outstanding, such affirmative vote of the holders of
the Shares is not required.
 
     The Company has advised Purchaser that as of June 26, 1997, 17,126,609
Shares were issued and outstanding and that (i) no Shares were held by the
subsidiaries of the Company and (ii) 2,882,657 Shares were reserved for future
issuance to present or former employees or directors pursuant to employee and
director stock options granted pursuant to the Company's stock option plans. As
a result, as of the date of this Offer to Purchase, the Minimum Condition would
be satisfied if Purchaser acquired pursuant to the Offer 16,007,413 Shares
(assuming that all Shares reserved for issuance pursuant to the Company's stock
option plans are outstanding at the Expiration Date).
 
     The Merger Agreement also provides that, as promptly as reasonably
practicable after the date of the Merger Agreement, but in no event later than
five business days after the first public announcement of the execution thereof,
and upon the terms and subject to the conditions of the Merger Agreement, Parent
or its designee shall make a cash tender offer (the "Note Offer to Purchase")
for any or all of the Notes. In connection with such Note Offer to Purchase,
Parent or its designee intends to solicit consents ("Consents") from the holders
of the Notes to amend certain provisions of the Indenture, dated as of April 15,
1996 (the "Indenture"), between the Company and IBJ Schroder Bank & Trust
Company, as trustee (the "Consent Solicitation" and together with the Note Offer
to Purchase, the "Note Tender Offer") so that such provisions are not applicable
to the Merger or following the consummation of the Note Tender Offer or the
Merger. The Note Tender Offer will be made at a price of 120% of the principal
amount of the Notes and is subject to the condition that Parent receive Consents
from the holders of a majority of the outstanding principal amount of the Notes
and to other conditions. See Section 14.

     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; EXPIRATION DATE.  Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of such extension or amendment), Purchaser will accept for
payment and pay for all Shares validly tendered prior to the Expiration Date (as
hereinafter defined) and not withdrawn as permitted by Section 4. The term
"Expiration Date" means 12:00 midnight, New York City time, on Wednesday, July
30, 1997, unless and until Purchaser, in its sole discretion (but subject to the
terms and conditions of the Merger Agreement), shall have extended the period
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 Purchaser,
shall expire.
 
     Subject to the applicable regulations of the Securities and Exchange
Commission (the "Commission"), Purchaser also expressly reserves the right, in
its sole discretion (but subject to the terms and conditions of the Merger
Agreement), at any time and from time to time, (i) to delay acceptance for
payment of, or, regardless of whether such Shares were theretofore accepted for
payment, payment for, any Shares pending receipt of any regulatory approval
specified in Section 15, (ii) to terminate the Offer and not accept for payment
any Shares upon the occurrence of any of the conditions specified in Section 14
and (iii) to waive any condition or otherwise amend the Offer in any respect, by
giving oral or written notice of such delay, termination, waiver or amendment to
the Depositary and by making a public announcement thereof. The Merger Agreement
provides that, without the consent of the Company, Purchaser will not (i)
decrease the price per Share payable pursuant to the Offer, (ii) change the form
of consideration payable pursuant to the Offer, (iii) reduce the maximum number
of Shares sought pursuant to the Offer, (iv) extend the expiration date of the
Offer (except that Purchaser may extend the expiration date of the Offer (a) as
required to comply with any rule, regulation or interpretation of the Commission
or (b) for one or more times each for an aggregate period of up to 15 days (and
not to exceed 60 days from the commencement of the Offer) for any reason other
than those specified in the immediately preceding clause (a)) or (v) impose
conditions to the Offer in addition to those set forth in Section 14. During any
extension, all Shares previously tendered and not withdrawn will remain subject
to the Offer, subject to the rights of a tendering stockholder to withdraw his
or her Shares. See Section 4. Purchaser acknowledges that (i) Rule 14e-1(c)
under the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
requires Purchaser to pay the consideration offered or return the Shares
tendered promptly after the termination or withdrawal of the Offer and (ii)
Purchaser may not delay acceptance for payment of, or payment for (except as
provided in clause (i) of the first sentence of this paragraph), any Shares upon
the occurrence of the conditions specified in Section 14 without extending the
period of time during which the Offer is open.
 
     Any such extension, delay, termination, waiver or amendment will be
followed as promptly as practicable by public announcement thereof, such
announcement in the case of an extension to be made no later than 9:00 a.m., New
York City time, on the next business day after the previously scheduled
Expiration Date. Subject to applicable law (including Rules 14d-4(c) and
14d-6(d) under the Exchange Act, which require that material changes be promptly
disseminated to stockholders in a manner reasonably designed to inform them of
such changes) and without limiting the manner in which Purchaser may choose to
make any public announcement, Purchaser shall have no obligation to publish,
advertise or otherwise communicate any such public announcement other than by
issuing a press release to the Dow Jones News Service.
 
     If Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer, Purchaser will extend the Offer to the extent
required by Rules 14d-4(c) and 14d-6(d) under the Exchange Act.
 
     Subject to applicable law, if, prior to the Expiration Date, Purchaser
should decide to increase the consideration being offered in the Offer, such
increase in the consideration being offered will be applicable to all
stockholders whose Shares are accepted for payment pursuant to the Offer and,
if, at the
 
                                        3
<PAGE>   6
 
time notice of any such increase in the consideration being offered is first
published, sent or given to holders of such Shares, the Offer is scheduled to
expire at any time earlier than the period ending on the tenth business day from
and including the date that such notice is first so published, sent or given,
the Offer will be extended at least until the expiration of such
ten-business-day period.
 
     The Company has provided Purchaser with the Company's stockholder list 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 related materials will be mailed to record holders of Shares whose names
appear on the Company's stockholder list and will be furnished, for subsequent
transmittal to beneficial owners of Shares, to brokers, dealers, commercial
banks, trust companies and similar persons whose names, or the names of whose
nominees, appear on the stockholder list or, if applicable, who are listed as
participants in a clearing agency's security position listing.
 
     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), Purchaser
will accept for payment all Shares validly tendered prior to the Expiration Date
and not withdrawn promptly after the latest to occur of (i) the Expiration Date,
(ii) the expiration or termination of any applicable waiting periods under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), and (iii) the satisfaction or waiver of the other conditions to the Offer
set forth in Section 14, and will promptly pay for all Shares accepted for
payment subject to the expiration or termination of any applicable waiting
periods under the HSR Act. Subject to applicable rules of the Commission,
Purchaser expressly reserves the right to delay acceptance for payment of, or
payment for, Shares pending receipt of any regulatory approvals specified in
Section 15 or in order to comply in whole or in part with any other applicable
law.
 
     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 (a "Book-Entry Confirmation") of a book-entry transfer of such
Shares into the Depositary's account at The Depository Trust Company or the
Philadelphia Depository Trust Company (each, a "Book-Entry Transfer Facility"
and, collectively, the "Book-Entry Transfer Facilities") pursuant to the
procedures set forth in Section 3, (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 below) in connection
with a book-entry transfer and (iii) any other documents required under the
Letter of Transmittal.
 
     The term "Agent's Message" means a message, transmitted by a Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility has
received an express acknowledgment from the participant in such 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 such participant.
 
     Parent anticipates filing with the Federal Trade Commission (the "FTC") and
the Antitrust Division of the Department of Justice (the "Antitrust Division"),
on July 7, 1997, a Premerger Notification and Report Form under the HSR Act in
connection with the purchase of Shares pursuant to the Offer. Accordingly, it is
anticipated that the waiting period under the HSR Act applicable to the Offer
will expire at 11:59 p.m., New York City time, on Tuesday, July 22, 1997. Prior
to the expiration or termination of such waiting period, the FTC or the
Antitrust Division may extend such waiting period by requesting additional
information or documentary material from Parent. If such a request is made with
respect to the purchase of Shares in the Offer, the waiting period will expire
at 11:59 p.m., New York City time, on the tenth calendar day after substantial
compliance by Parent with such a request. Thereafter, the waiting period may
only be extended by court order. The waiting period under the HSR Act may be
terminated prior to its expiration by the FTC and the Antitrust Division. Parent
will request early termination of the waiting period, although there can be no
assurance that this request will be granted. Pursuant to the Merger Agreement,
Purchaser may, but need not, extend the Offer until the applicable waiting
period
 
                                        4
<PAGE>   7
 
under the HSR Act shall have expired or been terminated. See Section 15 for
additional information regarding the HSR Act.
 
     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered and not withdrawn as, if
and when Purchaser gives oral or written notice to the Depositary of Purchaser's
acceptance for payment of such Shares pursuant to the Offer. Upon the terms and
subject to the conditions of the Offer, payment for Shares accepted for payment
pursuant to the Offer will be made by deposit of the purchase price therefor
with the Depositary, which will act as agent for tendering stockholders for the
purpose of receiving payments from Purchaser and transmitting such payments to
tendering stockholders whose Shares have been accepted for payment. Under no
circumstances will interest on the purchase price for Shares be paid, regardless
of any delay in making such payment.
 
     If any tendered Shares are not accepted for payment for any reason pursuant
to the terms and conditions of the Offer, or if Share Certificates are submitted
evidencing more Shares than are tendered, Share Certificates evidencing
unpurchased Shares will be returned, without expense to the tendering
stockholder (or, in the case of Shares tendered by book-entry transfer into the
Depositary's account at a Book-Entry Transfer Facility pursuant to the procedure
set forth in Section 3, such Shares will be credited to an account maintained at
such Book-Entry Transfer Facility), as promptly as practicable following the
expiration or termination of the Offer.
 
     3. PROCEDURES FOR TENDERING SHARES.  In order for a holder of Shares
validly to tender Shares pursuant to the Offer, the Letter of Transmittal (or a
facsimile thereof), properly completed and duly executed, together with any
required signature guarantees, or an Agent's Message in connection with a
book-entry delivery of Shares, and any other documents required by the Letter of
Transmittal, must be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase and either (i) the Share
Certificates evidencing tendered Shares must be received by the Depositary at
such address or such Shares must be tendered pursuant to the procedure 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 stockholder must comply with the guaranteed delivery procedures
described below.
 
     THE METHOD OF DELIVERY OF SHARE CERTIFICATES AND ALL OTHER REQUIRED
DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY TRANSFER FACILITY, IS AT
THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, 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.
 
     Book-Entry Transfer.  The Depositary will establish accounts with respect
to the Shares at the Book-Entry Transfer Facilities for purposes of the Offer
within two business days after the date of this Offer to Purchase. Any financial
institution that is a participant in the system of any Book-Entry Transfer
Facility may make a book-entry delivery of Shares by causing such Book-Entry
Transfer Facility to transfer such Shares into the Depositary's account at such
Book-Entry Transfer Facility in accordance with such Book-Entry Transfer
Facility's procedures for such transfer. However, although delivery of Shares
may be effected through book-entry transfer at a Book-Entry Transfer Facility,
the Letter of Transmittal (or a facsimile thereof), properly completed and duly
executed, together with any required signature guarantees, or an Agent's Message
in connection with a book-entry transfer, and any other required documents,
must, in any case, be received by the Depositary at one of its addresses set
forth on the back cover of this Offer to Purchase prior to the Expiration Date,
or the tendering stockholder must comply with the guaranteed delivery procedure
described below. DELIVERY OF DOCUMENTS TO A BOOK-ENTRY TRANSFER FACILITY DOES
NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
     Signature Guarantees.  Signatures on all Letters of Transmittal must be
guaranteed by a firm that is a member of the New York Stock Exchange Medallion
Signature Guarantee Program, or by any other "eligible guarantor institution,"
as such term is defined in Rule 17Ad-15 under the Exchange Act (each of
 
                                        5
<PAGE>   8
 
the foregoing being referred to as an "Eligible Institution"), except in cases
where Shares are tendered (i) by a registered holder of Shares who has not
completed either the box entitled "Special Payment Instructions" or the box
entitled "Special Delivery Instructions" on the Letter of Transmittal or (ii)
for the account of an Eligible Institution. If a Share Certificate is registered
in the name of a person other than the person who or which signs 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 by an Eligible Institution.
See Instructions 1 and 5 of the Letter of Transmittal.
 
     Guaranteed Delivery.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's Share Certificates evidencing such Shares are
not immediately available or such stockholder cannot deliver the Share
Certificates and all other required documents to the Depositary prior to the
Expiration Date, or such stockholder cannot complete the procedure for delivery
by book-entry transfer on a timely basis, such Shares may nevertheless be
tendered, provided that all the following conditions are satisfied:
 
          (i) such tender is 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 Purchaser, is
     received prior to the Expiration Date by the Depositary as provided below;
     and
 
          (iii) the Share Certificates (or a Book-Entry Confirmation) evidencing
     all tendered Shares, in proper form for transfer, in each case together
     with the 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 the Letter of Transmittal are received by the Depositary within
     three trading days on the New York Stock Exchange after the date of
     execution of such Notice of Guaranteed Delivery.
 
     The Notice of Guaranteed Delivery may be delivered by hand or mail or
transmitted by facsimile transmission to the Depositary and must include a
guarantee, in the form set forth in the form of Notice of Guaranteed Delivery
made available by Purchaser, by a firm which is a member of a registered
national securities exchange or of the National Association of Securities
Dealers, Inc. or which is a commercial bank or trust company having an office or
correspondent in the United States that is a member in good standing of the
Securities Transfer Agents Medallion Program, the New York Stock Exchange
Medallion Signature Guarantee Program or the Stock Exchange Medallion Program.
 
     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
Share Certificates evidencing such Shares, or a Book-Entry Confirmation of the
delivery of such Shares, and the 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 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 tender
of Shares will be determined by Purchaser in its sole discretion, which
determination shall be final and binding on all parties. Purchaser reserves the
absolute right to reject any and all tenders determined by it not to be in
proper form or the acceptance for payment of which may, in the opinion of its
counsel, be unlawful. Purchaser also reserves the absolute right to waive any
condition of the Offer or any defect or irregularity in the tender of any Shares
of any particular stockholder, whether or not similar defects or irregularities
are waived in the case of other stockholders. No tender of Shares will be deemed
to have been validly made until all defects and irregularities have been cured
or waived. None of Purchaser, Parent, the Dealer Managers, the Depositary, the
Information Agent or any other person will be under any duty to give
notification of any defects or irregularities in
 
                                        6
<PAGE>   9
 
tenders or incur any liability for failure to give any such notification.
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.
 
     Other Requirements.  By executing the Letter of Transmittal as set forth
above, a tendering stockholder irrevocably appoints designees of Purchaser as
such stockholder's proxies, each with full power of substitution, in the manner
set forth in the Letter of Transmittal, to the full extent of such stockholder's
rights with respect to the Shares tendered by such stockholder and accepted for
payment by Purchaser (and with respect to any and all other dividends,
distributions, Shares and other securities declared, paid or distributed in
respect of such Shares on or after June 23, 1997). All such proxies shall be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, Purchaser accepts such
Shares for payment. Upon such acceptance for payment, all prior proxies given by
such stockholder with respect to such Shares (and such other dividends,
distributions, Shares and other securities) will be revoked without further
action, and no subsequent proxies may be given nor any subsequent written
consent executed by such stockholder (and, if given or executed, will not be
deemed to be effective) with respect thereto. The designees of Purchaser will,
with respect to the Shares for which the appointment is effective, be empowered
to exercise all voting and other rights of such stockholder as they in their
sole discretion may deem proper at any annual or special meeting of the
Company's stockholders or any adjournment or postponement thereof, by written
consent in lieu of any such meeting or otherwise. Purchaser reserves the right
to require that, in order for Shares to be deemed validly tendered, immediately
upon Purchaser's payment for such Shares, Purchaser must be able to exercise
full voting rights with respect to such Shares (and such other Shares and
securities).
 
     The acceptance for payment by Purchaser of Shares pursuant to any of the
procedures described above will constitute a binding agreement between the
tendering stockholder and Purchaser upon the terms and subject to the conditions
of the Offer.
 
     UNDER THE FEDERAL INCOME TAX LAWS, THE DEPOSITARY WILL BE REQUIRED TO
WITHHOLD 31 PERCENT OF THE AMOUNT OF ANY PAYMENTS MADE TO CERTAIN STOCKHOLDERS
PURSUANT TO THE OFFER. TO PREVENT SUCH BACKUP FEDERAL INCOME TAX WITHHOLDING
WITH RESPECT TO PAYMENT TO CERTAIN STOCKHOLDERS OF THE PURCHASE PRICE OF SHARES
PURCHASED PURSUANT TO THE OFFER, EACH SUCH STOCKHOLDER MUST PROVIDE THE
DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER IDENTIFICATION NUMBER AND
CERTIFY THAT SUCH STOCKHOLDER IS NOT SUBJECT TO BACKUP FEDERAL INCOME TAX
WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9 IN THE LETTER OF TRANSMITTAL.
SEE INSTRUCTION 9 OF THE LETTER OF TRANSMITTAL.
 
     4. WITHDRAWAL RIGHTS.  Tenders of Shares made pursuant to the Offer are
irrevocable except that such Shares may be withdrawn by the tendering
stockholder at any time prior to the Expiration Date and, unless theretofore
accepted for payment by Purchaser pursuant to the Offer, may also be withdrawn
by such stockholder at any time after August 30, 1997. If Purchaser extends the
Offer, is delayed in its acceptance for payment of Shares or is unable to accept
Shares for payment pursuant to the Offer for any reason, then, without prejudice
to Purchaser's rights under the Offer, the Depositary may, nevertheless, on
behalf of Purchaser, retain tendered Shares, and such Shares may not be
withdrawn except to the extent that tendering stockholders are entitled to
withdrawal rights as described in this Section 4. Any such delay will be by an
extension of the Offer to the extent required by law.
 
     For a withdrawal to be effective, a written or facsimile transmission
notice of withdrawal must be timely received by the Depositary at one of its
addresses set forth on the back cover page 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 of such Shares, 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 shown on
such Share Certificates must be
 
                                        7
<PAGE>   10
 
submitted to the Depositary and the signature(s) on the notice of withdrawal
must be guaranteed by an Eligible Institution, unless such Shares have been
tendered for the account of an Eligible Institution. If Shares have been
tendered pursuant to the procedure for book-entry transfer as set forth in
Section 3, any notice of withdrawal must also specify the name and number of the
account of the Book-Entry Transfer Facility to be credited with the withdrawn
Shares, in which case a notice of withdrawal will be effective if delivered to
the Depositary by any method of delivery described in the first sentence of this
paragraph. Withdrawals of Shares may not be rescinded. Any Shares properly
withdrawn will thereafter be deemed not to have been validly tendered for
purposes of the Offer. However, withdrawn Shares may be re-tendered at any time
prior to the Expiration Date by following one of the procedures described in
Section 3.
 
     All questions as to the form and validity (including time of receipt) of
any notice of withdrawal will be determined by Purchaser, in its sole
discretion, whose determination will be final and binding. None of Purchaser,
Parent, the Dealer Managers, 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.
 
     5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.  The receipt of cash for Shares
pursuant to the Offer or in the Merger (or pursuant to the exercise of
dissenter's rights) will be a taxable transaction for federal income tax
purposes and may also be a taxable transaction under applicable state, local or
foreign tax laws. In general, a stockholder will recognize gain or loss for
federal income tax purposes equal to the difference between the amount of cash
received in exchange for the Shares sold and such stockholder's adjusted tax
basis in such Shares. Gain or loss will be calculated separately for each
identifiable block of Shares sold. For federal income tax purposes, such gain or
loss will be capital gain or loss if the Shares are capital assets in the hands
of such stockholder, and will be long-term capital gain or loss if such Shares
have been held for more than one year. A stockholder's ability to deduct capital
losses may be limited.
 
     Withholding.  Unless a stockholder complies with certain reporting and/or
certification procedures or is an exempt recipient under applicable provisions
of the Internal Revenue Code of 1986, as amended, and Treasury Regulations
promulgated thereunder, such stockholder may be subject to backup withholding at
a rate of 31% with respect to any consideration received pursuant to the Offer
and the Merger. See Section 3. Stockholders should consult their brokers to
ensure compliance with such procedures. Foreign stockholders should consult with
their own tax advisors regarding withholding taxes.
 
     THE FOREGOING DISCUSSION MAY NOT BE APPLICABLE TO CERTAIN TYPES OF
STOCKHOLDERS, INCLUDING FINANCIAL INSTITUTIONS, BROKER-DEALERS, STOCKHOLDERS WHO
ACQUIRED SHARES PURSUANT TO THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE
AS COMPENSATION, INDIVIDUALS WHO ARE NOT CITIZENS OR RESIDENTS OF THE UNITED
STATES AND FOREIGN CORPORATIONS.
 
     THE FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR GENERAL
INFORMATION ONLY AND IS BASED UPON PRESENT LAW. STOCKHOLDERS ARE URGED TO
CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE SPECIFIC TAX CONSEQUENCES OF THE
OFFER AND THE MERGER TO THEM, INCLUDING THE APPLICABILITY AND EFFECT OF ANY
STATE, LOCAL AND FOREIGN TAX LAWS.

forth herein, the information concerning the Company contained in this Offer to
Purchase, including financial information, has been furnished by the Company or
has been taken from or based upon publicly available documents and records on
file with the Commission and other public sources. Neither Purchaser, Parent nor

     General.  The Company is a Delaware corporation with its principal
executive offices located at 1009 Lenox Drive, Building Four West,
Lawrenceville, New Jersey 08648. The Company is an integrated multinational
industrial manufacturer of a broad range of industrial products through its five
core business segments -- Power Transmission, Pumps, Instrumentation, Morse
Controls and Roltra-Morse. The Company's products are designed to regulate and
control motion, transfer liquids and monitor fluids. The Company markets its
products on a worldwide basis to a diverse customer base. In November 1996, the
Company announced that it was withdrawing Roltra-Morse from divestiture because
threats made by an unsuccessful bidder made it impossible for the Company to
receive fair value for the business. As a result of this announcement,
Roltra-Morse has been reclassified as a continuing operation and the Company has
re-focused its operations on its five core business segments, as follows:
 
     The Power Transmission business segment designs and produces electronic
adjustable-speed motor drives, gears and speed reducers.
 
     The Pumps business segment designs and produces a broad range of rotary
pumps, including a proprietary line of two and three-screw pumps.
 
     The Instrumentation business segment designs and produces transducers and
switches for sensing, measuring and controlling pressure, temperature and liquid
level and flow.

     In connection with Parent's review of the Company and in the course of the
negotiations between Parent and the Company described in Section 10, the Company
provided Parent with certain business and financial information, including
unaudited financial data for the five months ended May 31, 1997, including sales
of $203.7 million, earnings before interest and income taxes of $2.7 million and
net loss of $12.4 million.
 
     The Company has advised Parent and Purchaser that it does not as a matter
of course make public forecasts as to future performance or earnings. However,
in connection with Parent's due diligence review of the Company described in
Section 10, the Company provided to Parent and Purchaser certain projections
relating to the Company's forecasted operating results for future periods,
including 1997, 1998 and 1999. Parent and Purchaser have been advised that such
information was prepared by the Company solely as part of the Company's annual
planning process, independent of the Company's potential sale to Parent or
Purchaser. Such projections included forecasts of sales of $485.9 million,
$521.0 million and $564.0 million, gross profit of $146.1 million, $163.9
million and $181.1 million, income from operations of $22.7 million, $41.3
million and $53.1 million and net income (loss) of $(13.6 million), $5.1 million
and $16.1 million for 1997, 1998 and 1999, respectively.
 
     PROJECTED INFORMATION OF THIS TYPE IS BASED ON ESTIMATES AND ASSUMPTIONS
THAT ARE INHERENTLY SUBJECT TO SIGNIFICANT ECONOMIC AND COMPETITIVE
UNCERTAINTIES AND CONTINGENCIES, ALL OF WHICH ARE DIFFICULT TO PREDICT AND MANY
OF WHICH ARE BEYOND THE COMPANY'S CONTROL. THESE FORWARD-LOOKING STATEMENTS ARE
SUBJECT TO CERTAIN RISKS AND UNCERTAINTIES THAT COULD CAUSE ACTUAL RESULTS TO
DIFFER MATERIALLY FROM THESE PROJECTIONS. THESE PROJECTIONS REFLECT NUMEROUS
ASSUMPTIONS, ALL MADE BY MANAGEMENT OF THE COMPANY, WITH RESPECT TO INDUSTRY
PERFORMANCE, GENERAL BUSINESS, ECONOMIC, MARKET AND FINANCIAL CONDITIONS AND
OTHER MATTERS INCLUDING ASSUMED INTEREST EXPENSE AND EFFECTIVE TAX RATES
CONSISTENT WITH HISTORICAL LEVELS FOR THE COMPANY, ALL OF WHICH ARE DIFFICULT TO
PREDICT, MANY OF WHICH ARE BEYOND THE COMPANY'S CONTROL AND NONE OF WHICH WERE
SUBJECT TO APPROVAL BY PARENT OR PURCHASER. ACCORDINGLY, THERE CAN BE NO
ASSURANCE THAT THE PROJECTED RESULTS WILL BE REALIZED OR THAT ACTUAL RESULTS
WILL NOT BE SIGNIFICANTLY HIGHER OR LOWER THAN THOSE SET FORTH ABOVE. IN
ADDITION, THESE PROJECTIONS WERE NOT PREPARED WITH A VIEW TO PUBLIC DISCLOSURE
OR COMPLIANCE WITH THE PUBLISHED GUIDELINES OF THE COMMISSION OR THE GUIDELINES
ESTABLISHED BY THE AMERICAN INSTITUTE OF CERTIFIED PUBLIC ACCOUNTANTS REGARDING
PROJECTIONS AND FORECASTS AND ARE INCLUDED IN THIS OFFER TO PURCHASE ONLY
BECAUSE SUCH INFORMATION WAS MADE AVAILABLE TO PARENT BY THE COMPANY. NONE OF
PARENT, PURCHASER, THE COMPANY, THEIR FINANCIAL ADVISORS OR ANY OTHER ENTITY OR
PERSON ASSUMES ANY RESPONSIBILITY FOR THE ACCURACY OR VALIDITY OF THE FOREGOING
PROJECTIONS. NONE OF PARENT, PURCHASER, THE COMPANY OR ANY OF THEIR FINANCIAL

     8. CERTAIN INFORMATION CONCERNING PURCHASER AND PARENT.  Purchaser is a
newly incorporated Delaware corporation organized in connection with the Offer
and the Merger and has not carried on any activities other than in connection

     On June 25, 1997, Parent entered into an Agreement and Plan of Merger (the
"Core Merger Agreement") with UD Nevada Corp., a Nevada corporation and an
indirect wholly owned subsidiary of Parent ("UD Nevada"), and Core Industries

Nevada has agreed to make an offer to purchase all of the outstanding shares of
common stock of Core and, subject to the terms and conditions thereof, to merge
UD Nevada with and into Core. The Offer is not conditioned upon consummation of
any of the transactions contemplated by the Core Merger Agreement, and there is
no assurance that any of such transactions will be consummated.

     Principal Differences Between Canadian and United States Generally Accepted
Accounting Principles.  The financial information provided above was prepared in
accordance with Canadian GAAP, which differs in certain significant respects
from U.S. GAAP. These differences relate principally to the following items, and
the necessary adjustments are set out below.
 
     Canadian GAAP allows for the reduction of stated capital of outstanding
common shares with a corresponding offset to deficit. This reclassification,
which Parent made in 1990, is not permitted by U.S. GAAP and would result in an
increase in capital stock and a reduction in retained earnings at December 31,
1996 and 1995 and at March 31, 1997 and 1996 of $128,093,000. Canadian GAAP also
permits expenses related to the issue of capital stock, net of income taxes, to
be deducted from retained earnings while U.S. GAAP requires such expenses to be
deducted from the proceeds of stock issuances credited to capital stock. This
reclassification would reduce capital stock and increase retained earnings by
$20,905,000 at March 31, 1997, December 31, 1996 and March 31, 1996 and
$17,427,000 at December 31, 1995.
 
     Under Canadian GAAP, the discount rate used for computing the benefit
obligation and the service and interest cost components of net periodic pension
expense represents management's best estimate of the long-term rate of return on
pension fund assets; whereas, under U.S. GAAP the discount rate reflects the
rate at which pension benefits can be effectively settled at the date of the
financial statements.
 
     U.S. GAAP requires accruing the cost of providing post-retirement benefits
other than pensions to employees and their beneficiaries (e.g., health care
benefits) during the years that the employee renders the necessary service.
Parent records expense on a "pay-as-you-go" basis for benefits paid on behalf of
 
                                       15
<PAGE>   18
 
retired employees. At March 31, 1997, the accumulated benefit obligation not
recorded by Parent totaled approximately $9,000,000.
 
     In 1996, Parent recognized certain tax benefits related to prior year
acquisitions that under U.S. GAAP would have reduced goodwill.
 
     U.S. GAAP requires the use of an asset and liability approach to accounting
for income taxes; whereas, Canadian GAAP requires the use of the deferral
method.
 
     The following table reflects the impact on Parent's net income and net
earnings per share of complying with U.S. GAAP as it pertains to the items noted
above.

     U.S. GAAP generally requires the use of the equity method of accounting for
investments in joint ventures. Accordingly, Parent's proportionate share of its
joint ventures' assets, liabilities, sales and expenses would not be reflected
in the above financial data under U.S. GAAP. This change in presentation would
not affect net income.
 
     The application of U.S. GAAP discussed above would result in increases in
other (non-current) assets of approximately $17,000,000 and other liabilities of
approximately $36,000,000 and decreases in current assets of approximately
$23,000,000, current liabilities of approximately $16,000,000, long-term debt of
$8,000,000 and total shareholders' equity of approximately $18,000,000 as of
March 31, 1997.
 
     9. FINANCING OF THE OFFER AND THE MERGER.  The total amount of funds
required by Purchaser to consummate the Offer, the Merger and the Note Tender
Offer, to refinance the Company's obligations under the Credit Agreement, dated
as of April 29, 1996 (as amended, the "Company Credit Agreement"), among the
Company, Varo Inc., Warren Pumps Inc., the lenders from time to time party
thereto, the issuing banks from time to time party thereto and Citicorp USA,
Inc., as Agent, and to satisfy certain obligations of the Company under the
Indenture and to pay related fees and expenses is estimated to be approximately
$460 million. Purchaser will obtain all of such funds from Parent and its
affiliates. Affiliates of Parent currently intend to provide such funds from
cash on hand and funds available pursuant to new credit facilities (the "New
Credit Facilities") in the aggregate amount of $800 million for which Parent
 
                                       16
<PAGE>   19
 
and United Dominion Industries, Inc. (together, the "Borrower") have received a
commitment (the "Commitment") from the Royal Bank of Canada (New York Branch)
("RBC"). It is anticipated that the initial borrowings under the New Credit
Facilities will be used, among other things, to provide a portion of the funds
required to consummate the Offer, the Merger and the Note Tender Offer, to
provide a portion of the funds necessary to consummate the transactions
contemplated by the Core Merger Agreement, to pay related fees and expenses and
to repay outstanding balances under existing credit facilities of Parent and its
affiliates (the "Existing Credit Facilities") established pursuant to a
$300,000,000 Amendment and Restatement of the Credit Agreement and Guaranty
dated as of June 20, 1996 among Parent and United Dominion Industries, Inc., as
obligors, RBC, as agent, and certain financial institutions signatory thereto,
as lenders, as amended, and to provide the Company with sufficient funds to
refinance the Company Credit Agreement and satisfy certain of the Company's
obligations under the Indenture. At June 30, 1997, the aggregate outstanding
principal balance under the Existing Credit Facilities was approximately $19
million.
 
     The New Credit Facilities will consist of two components: a $650 million
five-year revolving credit facility, including a $75 million sub-limit for the
issuance of standby letters of credit (the "Five-Year Facility"), and a $150
million 364-day revolving credit facility (the "Bridge Facility"). Borrowings
under the New Credit Facilities will be available in all freely available
currencies, including U.S. Dollars and German Deutsche Marks, subject to certain
limitations. Interest will be payable, at the Borrower's option, at (i) the
higher of a U.S. reference lender's prime interest rate or the federal funds
rate plus 0.50% per annum, (ii) the interbank offered rate for Eurodollar
deposits of 1, 2, 3, 6, 9 or 12 months plus a margin, or (iii) the interbank
offered rate for Euro-Deutsche Mark deposits of 1, 2, 3, 6, 9 or 12 months plus
a margin. The New Credit Facilities will require the payment of a quarterly
facility fee ranging from 0.08% to 0.125% per annum on the aggregate commitments
under the Five-Year Facility and from 0.06% to 0.10% per annum on the aggregate
commitments under the Bridge Facility, and will also require payment of a
utilization fee of 0.05% per annum on the daily average of all outstanding
balances if utilization exceeds 50% of the aggregate commitments, if the
Parent's public debt is not rated at or above certain rating levels and if the
highest pricing margin then applies. The New Credit Facilities will not be
secured by collateral. RBC has the right to syndicate all or a portion of the
New Credit Facilities.
 
     The definitive credit agreement for the New Credit Facilities is expected
to provide for various representations, warranties and covenants of Parent. The
covenants are expected to be typical for a facility of this type, to include,
without limitation, customary affirmative covenants designed to ensure the
continued existence of Parent, the sound operation of its businesses and the
businesses of its subsidiaries, the proper maintenance and insurance of
properties, the provision of financial statements, the payment of debts and
taxes and continued compliance with applicable law, and customary negative
covenants regarding, on a consolidated basis, (i) additional indebtedness, (ii)
asset dispositions and expenditures, (iii) financial ratios, (iv) contingent
liabilities, (v) loans and advances, (vi) liens and security interests, (vii)
dividends and purchases of stock and (viii) transactions with affiliates. Such
negative covenants with respect to asset dispositions and liens are expected to
expressly except from their coverage the sale, disposition, pledge or
encumbrance by Parent or any of its subsidiaries of "margin stock" as defined in
Regulation U of the Federal Reserve Board to the extent the fair market value of
margin stock exceeds 25% of the fair market value of the property and assets
(including the margin stock) of Parent or such subsidiary.
 
     Under the definitive credit agreement, Parent will agree to hold the agent
and each of the lenders harmless against any and all losses, liabilities,
claims, damages and expenses incurred or suffered by it arising out of or by
reason of any transaction financed with the proceeds of any borrowing and any
investigation, litigation or proceeding relating to the transactions
contemplated thereby.
 
     The funding of the New Credit Facilities will be subject to customary
conditions, including, among other things, the execution of satisfactory
documentation and the receipt of all necessary governmental approvals, and in
addition will be subject to the satisfaction of the Minimum Condition. Although
Parent expects that the New Credit Facilities will be available to provide funds
for the consummation of the Offer
 
                                       17
<PAGE>   20
 
and the Merger in accordance with their respective terms, there can be no
assurance that the New Credit Facilities will be consummated.
 
     The foregoing summary is subject to the preparation and completion of a
definitive credit agreement for the New Credit Facilities and is qualified in
its entirety by reference to the Commitment, a copy of which has been filed as
an exhibit to the Tender Offer Statement on Schedule 14D-1/13D (the "Schedule
14D-1") filed by Purchaser and Parent with the Commission in connection with the
Offer.
 
     Parent anticipates that indebtedness incurred through borrowings under the
New Credit Facilities will be repaid from a variety of sources, which may
include, but may not be limited to, funds generated internally by Parent and its
subsidiaries (including, following the Merger, funds generated by the Surviving
Corporation), bank financing, and the public or private sale of debt or equity
securities. No decision has been made concerning the method Parent will employ
to repay such indebtedness. Such decision will be made based on Parent's review
from time to time of the advisability of particular actions, as well as on
prevailing interest rates and financial and other economic conditions and such
other factors as Parent may deem appropriate.
 
     10. BACKGROUND OF THE OFFER; CONTACTS WITH THE COMPANY; THE MERGER
AGREEMENT.
 
     Background of the Offer; Contacts with the Company.  During the summer and
fall of 1996, Parent was approached by a number of investment banking firms
identifying the Company as a possible acquisition candidate. In November 1996,
Richard A. Bearse, Senior Vice President of Parent, through an investment
banking firm, contacted the Company to express Parent's interest in discussing a
possible business combination transaction with the Company.
 
     On March 21, 1997, the Company announced that it had engaged Credit Suisse
First Boston to assist it in evaluating strategic alternatives for enhancing
stockholder value and reducing leverage, including the possible merger or sale
of the Company. Following this announcement, financial advisors of Parent
arranged a meeting, held on April 8, 1997, between Mr. Bearse and William M.
Brown, the Company's Chief Financial Officer. At this meeting, Mr. Bearse
expressed Parent's interest in a possible business combination with the Company,
and Messrs. Bearse and Brown discussed the businesses of both Parent and the
Company. Following this meeting, the Company requested that Parent enter into a
confidentiality agreement as a condition to continuing discussions. On April 25,
1997, Parent entered into a confidentiality agreement with the Company agreeing
to keep certain information confidential and not to take certain action to
obtain control of the Company. See "Confidentiality Agreement" in this Section
10.
 
     On April 29, 1997, Jan K. Ver Hagen, Parent's President and Chief Operating
Officer, and Mr. Bearse, met with Donald K. Farrar, the Company's Chairman and
Chief Executive Officer, Mr. Brown and representatives of Credit Suisse First
Boston to discuss Company's operations, financial condition and prospects.
Following the meeting, Parent received a confidential information memorandum
prepared by Credit Suisse First Boston containing information concerning the
Company.
 
     On May 1, 1997, Mr. Bearse, through Parent's financial advisors, submitted
to Credit Suisse First Boston an oral expression of interest by Parent to
acquire the Company. Mr. Bearse discussed Parent's desire to preempt any attempt
to sell the Company through a process that sought bids from several interested
parties. Representatives of Credit Suisse First Boston informed Mr. Bearse that
the Company planned to proceed with discussions with other parties. As part of
this process, Credit Suisse First Boston requested that Parent submit an
expression of interest specifying a tentative price by June 2, at which time the
Company would evaluate all proposals and proceed with discussions among a
smaller group of potential candidates. On June 2, 1997, Parent submitted to
Credit Suisse First Boston its expression of interest to acquire the Company at
a price of $4.50 per Share. Credit Suisse First Boston informed representatives
of Parent that the tentative price specified in Parent's expression of interest
would not be sufficient to include it in the smaller group of potential
acquirors with whom further discussions would be held. On June 4, 1997, Parent
amended its expression of interest to indicate a range of tentative prices
between $4.50 and $6.00 per Share and was invited to continue discussions
regarding a potential acquisition.
 
                                       18
<PAGE>   21
 
     On June 12, 1997, J. Milton Childress, II, a Vice President of Parent,
notified Credit Suisse First Boston that Parent was withdrawing its expression
of interest because it did not wish to participate in a process involving other
potential bidders. On June 13, 1997, Mr. Bearse contacted Mr. Farrar to discuss
the reasons for Parent's withdrawal of its expression of interest. In subsequent
conversations that day among Mr. Bearse, Mr. Farrar and representatives of
Credit Suisse First Boston, the Company expressed its desire that Parent
continue to participate in the process being conducted by Credit Suisse First
Boston. Mr. Bearse reiterated Parent's position that it did not want to continue
in a process involving other bidders and that it would proceed with discussions
only if it was granted an exclusive period to examine the Company and negotiate
a definitive agreement. Later that day, following discussions involving William
R. Holland, Parent's Chairman and Chief Executive Officer, Parent and the
Company orally agreed that Parent would continue discussions and, upon Parent's
tentative agreement to increase its proposed price to $7.00 per Share, the
Company would provide Parent an exclusive period to examine the Company and
negotiate a definitive agreement. On June 16, 1997, Parent and the Company
entered into a letter agreement pursuant to which Parent and the Company agreed
to work diligently in good faith towards the preparation of a definitive merger
agreement, the execution of which would be subject to Parent's satisfactory
completion of due diligence, and the Company agreed that it would not negotiate
or solicit proposals for the sale or other disposition of the Company or its
assets until June 30, 1997 (or June 25, 1997, if Parent's Board of Directors did
not determine to proceed with the transaction by that date). See "Exclusivity
Agreement" in this Section 10.
 
     On June 16, 1997, members of senior management of Parent met with members
of the Company's senior management, business unit managers and corporate staff
to review the Company's businesses. During the next week and a half, Parent,
Purchaser, the Company, their financial advisors and legal counsel negotiated
the terms of a potential acquisition. In addition, during a portion of that
period Parent and its financial advisors and legal counsel conducted a business
review and due diligence investigation at various Company sites. In connection
with its due diligence review of the Company, Parent determined that certain
provisions of the indenture governing the Notes must be amended to permit the
Merger, and on June 23, 1997, representatives of Parent discussed with
representatives of the Company and Credit Suisse First Boston the feasibility of
a successful Note Tender Offer. On June 24, 1997, Mr. Holland informed Mr.
Farrar that as a result of its due diligence investigation (including Parent's
assessment of the magnitude of the Company's potential trailing liabilities with
respect to disposed business units and potential environmental liabilities) and
the substantial premium necessary to complete a successful Note Tender Offer,
Parent could not proceed with a transaction at $7.00 per Share and that Parent
proposed to acquire the Company for $5.00 per Share. On June 25, 1997, Mr.
Farrar informed Mr. Holland that the Company's Board of Directors had rejected
Parent's $5.00 per Share proposal, but that he would recommend that the
Company's Board of Directors approve a $6.00 per Share proposal if Parent not
condition the Offer on the successful completion of the Note Tender Offer. Mr.
Holland advised Mr. Farrar that Parent would proceed with a $6.00 per Share
proposal, but only if the Offer was conditioned on the successful completion of
the Note Tender Offer. Mr. Farrar advised Mr. Holland that he would present such
proposal to the Company's Board of Directors.
 
     Later on June 25, 1997, upon being advised that the Company's Board of
Directors had approved the Merger, Parent's Board of Directors approved the
Merger, the Offer, the Note Tender Offer and the other transactions contemplated
by the Merger Agreement. The Merger Agreement was executed by representatives of
Parent, Purchaser and the Company early in the morning of June 26, 1997, and
Parent and the Company announced the execution of the Merger Agreement later
that morning.
 
     The Merger Agreement.  The following is a summary of the Merger Agreement,
a copy of which has been filed as an Exhibit to the Schedule 14D-1 filed by
Purchaser and Parent with the Commission in connection with the Offer. Such
summary is qualified in its entirety by reference to the Merger Agreement.
Capitalized terms used herein and not otherwise defined herein shall have the
meanings ascribed thereto in the Merger Agreement.
 
     The Offer.  The Merger Agreement provides for the commencement of the Offer
as promptly as reasonably practicable, but in no event later than five business
days after the first public announcement
 
                                       19
<PAGE>   22
 
of the execution of the Merger Agreement. The obligation of Purchaser to accept
for payment Shares tendered pursuant to the Offer is subject to the satisfaction
of the Minimum Condition and certain other conditions that are described in
Section 14 hereof. Purchaser has expressly reserved the right to waive any such
condition, to increase the price per Share payable in the Offer, and to make any
other changes in the terms and conditions of the Offer; provided, however, that
Purchaser and Parent have agreed with the Company that, without the prior
consent of the Company, no change in the Offer may be made that decreases the
price per Share payable in the Offer, that changes the form of consideration
payable in the Offer, that reduces the maximum number of Shares sought pursuant
to the Offer, that extends the expiration date of the Offer (except that
Purchaser may extend the expiration date of the offer (a) as required to comply
with any rule, regulation or interpretation of the Commission or (b) for one or
more times each for an aggregate period of up to 15 days (and not to exceed 60
days from the date of commencement) for any reason other than those specified in
the immediately preceding clause (a)), or that imposes conditions to the Offer
in addition to those set forth in Section 14 hereof.
 
     The Merger.  The Merger Agreement provides that, upon the terms and subject
to the conditions thereof, and in accordance with Delaware Law, at the Effective
Time, Purchaser shall be merged with and into the Company. As a result of the
Merger, the separate corporate existence of Purchaser will cease and the Company
will continue as the Surviving Corporation and as an indirect wholly owned
subsidiary of Parent. Upon consummation of the Merger, each issued and then
outstanding Share (other than any Shares owned by Purchaser, Parent, the Company
or any wholly owned subsidiary of Parent or of the Company and any Shares that
are held by stockholders who have properly exercised their rights for appraisal
of such Shares in accordance with Delaware Law) shall be cancelled and converted
automatically into the right to receive the Merger Consideration.
 
     Pursuant to the Merger Agreement, each share of common stock, par value
$.01 per share, of Purchaser issued and outstanding immediately prior to the
Effective Time shall be converted into and exchanged for one share of common
stock, par value $1.00 per share, of the Surviving Corporation.
 
     The Merger Agreement provides that the directors of Purchaser immediately
prior to the Effective Time will be the initial directors of the Surviving
Corporation and that the officers of the Company immediately prior to the
Effective Time will be the initial officers of the Surviving Corporation. The
Merger Agreement also provides that, at the Effective Time, the Certificate of
Incorporation of the Company, as in effect immediately prior to the Effective
Time, shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended as provided by applicable law and such Certificate of
Incorporation. The Merger Agreement also provides that the Bylaws of the
Company, as in effect immediately prior to the Effective Time, will be the
Bylaws of the Surviving Corporation.
 
     Note Tender Offer.  Pursuant to the Merger Agreement, as promptly as
reasonably practicable after the date of the Merger Agreement, but in no event
later than five business days after the first public announcement of the
execution thereof, and upon the terms and subject to the conditions of the
Merger Agreement, Parent or its designee shall make the Note Offer to Purchase.
In connection with such Note Offer to Purchase, Parent or its designee intends
to solicit Consents from the holders of the Notes to amend the Indenture. The
proposed amendments to the Indenture would: (i) delete the covenants in the
Indenture entitled "Limitation on Restricted Payments," "Limitation on
Restrictions on Distributions from Restricted Subsidiaries," "Limitation on
Sales of Assets and Subsidiary Stock," "Limitation on Affiliate Transactions,"
"Limitation on the Sale or Issuance of Capital Stock of Restricted
Subsidiaries," "Limitation on Liens," "Limitation on Sale/Leaseback
Transactions" and "Specified Subsidiaries"; (ii) amend the section of the
Indenture entitled "When the Company may Merge or Transfer Assets" to eliminate
the requirement in connection with any such merger or sale that the Successor
Company (as defined therein) be able to incur an additional $1.00 of
indebtedness pursuant to the Indenture's restriction on indebtedness; (iii)
amend the section of the Indenture entitled "SEC Reports" to eliminate the
requirement that the Company provide the trustee under the Indenture and the
holders of the Notes with information and reports specified in Sections 13 and
15(d) of the Exchange Act notwithstanding that the Company may not then be
subject to the reporting requirements under such sections of the Exchange Act;
(iv) amend the section of the Indenture entitled "Limitation on Indebtedness" to
permit
 
                                       20
<PAGE>   23
 
the Company to incur indebtedness to an affiliate of the Company; and (v) amend
the section of the Indenture entitled "Limitation on Indebtedness and Preferred
Stock of Restricted Subsidiaries" to remove any limitation on a foreign
subsidiary's ability to incur indebtedness. Parent's obligation to accept for
payment and pay for the Notes and related Consents tendered pursuant to the Note
Tender Offer is subject to the condition that Parent receive Consents from the
holders of a majority of the outstanding principal amount of the Notes (the
"Requisite Consent Condition") and to other conditions. See Section 14. The Note
Tender Offer shall be made at a price of 120% of the principal amount of the
Notes, upon the terms and subject to the conditions of the Merger Agreement and
the Note Tender Offer. In the Merger Agreement, Parent expressly reserved the
right to waive any condition, to increase the price payable for each Note and
related Consent tendered in the Note Tender Offer, and to make any other changes
in the terms and conditions of the Note Tender Offer; provided, however, that,
without the consent of the Company, no change may be made which decreases the
price payable for each Note and related Consent tendered in the Note Tender
Offer, which changes the form of consideration to be paid in the Note Tender
Offer, which reduces the maximum number of Notes to be purchased in the Note
Tender Offer or which imposes additional conditions to the Note Tender Offer.
Subject to the terms and conditions of the Note Tender Offer (including, without
limitation, the Requisite Consent Condition), Parent has agreed in the Merger
Agreement to pay, as promptly as practicable after expiration of the Note Tender
Offer, for all Notes and related Consents validly tendered and not withdrawn.
Assuming the Requisite Consent Condition is satisfied and all other conditions
to the Note Tender Offer have been satisfied or waived by Parent, the Company
has agreed to execute, and to use all reasonable efforts to cause the trustee
under the Indenture to execute, a supplemental indenture (the "Supplemental
Indenture") in order to give effect to the amendments of the Indenture
contemplated in the Note Tender Offer immediately following the expiration date
of the Note Tender Offer; provided, however, that the proposed amendments set
forth in the Supplemental Indenture (the "Proposed Amendments") will not become
operative until the date Parent accepts all Notes (and related Consents) validly
tendered for purchase and payment pursuant to the Note Tender Offer. In such
event, the parties to the Merger Agreement have agreed that the Proposed
Amendments will be deemed effective as of the date immediately prior to such
acceptance for payment, and Parent will thereafter be obligated to make all
payments for the Notes (and related Consents) so tendered.
 
     Company Stockholders' Meeting; Proxy Statement.  Pursuant to the Merger
Agreement, in the event that the affirmative vote of the holders of Shares is
required to approve the Merger under Delaware Law, the Company shall duly call,
give notice of, convene and hold a special meeting of its stockholders as soon
as practicable following consummation of the Offer for the purpose of
considering and taking action on the Merger Agreement and the transactions
contemplated thereby (the "Stockholders' Meeting"). The Merger Agreement
provides that, in the event that the affirmative vote of holders of Shares is
required to approve the Merger, the Company shall, as soon as practicable
following consummation of the Offer, file with the Commission under the Exchange
Act, and use its best efforts to have cleared by the Commission, a proxy
statement and related proxy materials (the "Proxy Statement") with respect to
the Stockholders' Meeting and shall cause the Proxy Statement to be mailed to
stockholders of the Company at the earliest practicable time. The Company has
also agreed, subject to the fiduciary duties of the Board under applicable law
as advised by independent counsel, to include in the Proxy Statement the
unanimous recommendation of the Board that the stockholders of the Company
approve and adopt the Merger Agreement and the transactions contemplated thereby
and to use all reasonable efforts to obtain such approval and adoption. Parent
and Purchaser have each agreed to vote all Shares beneficially owned by them in
favor of the Merger.
 
     Conduct of Business.  Pursuant to the Merger Agreement, the Company has
covenanted and agreed that, between the date of the Merger Agreement and the
election or appointment of Purchaser's designees to serve on the Company's Board
of Directors (the "Purchaser's Election Date"), unless Parent shall otherwise
agree in writing, each of the Company and its Subsidiaries shall conduct its
business only in, and the Company and the Subsidiaries shall not take any action
except in, the ordinary course of business consistent with past practice; and
the Company shall use all reasonable efforts to preserve substantially intact
the business organization of the Company and its Subsidiaries, to keep
 
                                       21
<PAGE>   24
 
available the services of the current officers, employees and consultants of the
Company and its Subsidiaries and to preserve the current relationships of the
Company and its Subsidiaries with customers, suppliers and other persons with
which the Company or any Subsidiary has significant business relations. The
Merger Agreement also provides that, except with the prior written consent of
Parent or as contemplated by the Merger Agreement, the Company agrees that
neither the Company nor any Subsidiary shall, between the date of the Merger
Agreement and the Purchaser's Election Date, directly or indirectly do, or
propose to do, any of the following: (a) amend or otherwise change its
Certificate of Incorporation or Bylaws or equivalent organizational documents,
each as amended to date (the "Constituent Documents"); (b) issue, sell, pledge,
dispose of, grant, encumber, or authorize the issuance, sale, pledge,
disposition, grant or encumbrance of (i) any shares of capital stock of any
class of the Company or any Subsidiary, or any options, warrants, convertible
securities or other rights of any kind to acquire any shares of such capital
stock, or any other ownership interest (including, without limitation, any
phantom interest), of the Company or any Subsidiary (except for the issuance of
a maximum of 2,000,000 Shares issuable pursuant to Stock Option Plans
outstanding on the date thereof) or (ii) any assets of the Company or any
Subsidiary, except for sales in the ordinary course of business and in a manner
consistent with past practice; (c) declare, set aside, make or pay any dividend
or other distribution, payable in cash, stock, property or otherwise, with
respect to any of its capital stock, except for such declarations, set asides,
dividends and other distributions made by any Subsidiary to the Company; (d)
reclassify, combine, split, subdivide or redeem, purchase or otherwise acquire,
directly or indirectly, any of its capital stock; (e) (i) acquire (including,
without limitation, by merger, consolidation, or acquisition of stock or assets
or any other business combination) any corporation, partnership, other business
organization or any division thereof or any material amount of assets other than
in the ordinary course of business consistent with past practice; (ii) incur any
indebtedness for borrowed money or issue any debt securities or assume,
guarantee or endorse, pledge in respect of or otherwise as an accommodation
become responsible for the obligations of any person, or make any loans or
advances, except in the ordinary course of business and consistent with past
practice; (iii) enter into any contract or agreement, other than any contract or
agreement entered into in the ordinary course of business consistent with past
practice and which requires payments by the Company or its Subsidiaries in an
aggregate amount of less than U.S. $250,000; (iv) terminate, cancel or request
any material change in, or agree to any material change in, any Material
Contract, except in the ordinary course of business consistent with past
practice; or (v) authorize any single capital expenditure (excluding software
development activity) which is in excess of U.S. $500,000 or capital
expenditures which are, in the aggregate, in excess of U.S. $2,500,000 for the
Company and its Subsidiaries taken as a whole; (f) increase the compensation
payable or to become payable to its officers or employees, except for increases
in accordance with past practices in salaries or wages of employees of the
Company or any Subsidiary who are not officers of the Company, or grant any
severance or termination pay to, or enter into any employment or severance
agreement with, any director, officer or other employee of the Company or any
Subsidiary (other than in connection with hiring and terminating employees in
the ordinary course of the Company's business), or establish, adopt, enter into
or amend any collective bargaining, bonus, profit sharing, thrift, compensation,
stock option, restricted stock, pension, retirement, deferred compensation,
employment, termination or severance plan, agreement, trust, fund, policy or
arrangement for the benefit of any director, officer or employee or circulate to
any employee any details of any proposal to adopt or amend any such plan; (g)
take any action, other than reasonable and usual actions in the ordinary course
of business consistent with past practice, with respect to accounting policies
or procedures (including, without limitation, procedures with respect to the
payment of accounts payable and collection of accounts receivable); (h) make any
material tax election or settle or compromise any material federal, state, local
or foreign income tax liability; (i) pay, discharge or satisfy any claim,
liability or obligation (absolute, accrued, asserted or unasserted, contingent
or otherwise), other than the payment, discharge or satisfaction, in the
ordinary course of business consistent with past practice, of liabilities
reflected or reserved against on the Company's consolidated balance sheet
included in its Quarterly Report on Form 10-Q for the quarter ended March 31,
1997 or subsequently incurred in the ordinary course of business and consistent
with past practice; or (j) settle or comprise any pending or threatened suit,
action or claim that is material or which relates to any of the transactions
 
                                       22
<PAGE>   25
 
contemplated by the Merger Agreement; or (k) announce an intention, enter into
any formal or informal agreement, or otherwise make a commitment, to do any of
the foregoing.
 
     Designation of Directors.  The Merger Agreement provides that, promptly
upon the purchase by Purchaser of Shares pursuant to the Offer, and from time to
time thereafter, Purchaser shall be entitled to designate up to such number of
directors, rounded up to the next whole number, on the Board as shall give
Purchaser representation on the Board equal to the product of the total number
of directors on the Board (giving effect to the directors elected pursuant to
this sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Purchaser or any affiliate of Purchaser at such time bears
to the total number of Shares then outstanding. Pursuant to the Merger
Agreement, the Company agrees, at such time of purchase, to promptly take all
actions necessary to cause Purchaser's designees to be elected as directors of
the Company, including increasing the size of the Board or securing the
resignations of incumbent directors or both. The Merger Agreement also provides
that, at such times, the Company shall use all reasonable efforts to cause
persons designated by Purchaser to constitute the same percentage as persons
designated by Purchaser shall constitute of the Board with respect to (a) each
committee of the Board (some of whom may be required to be independent as
required by applicable law or requirements of the New York Stock Exchange, Inc.
(the "New York Stock Exchange")), (b) each board of directors of each Subsidiary
and (c) each committee of each such board, in each case only to the extent
permitted by applicable law. Notwithstanding the foregoing, the Merger Agreement
provides that until the time Purchaser acquires a majority of the then
outstanding Shares on a fully diluted basis, the Company shall use all
reasonable efforts to ensure that all the members of the Board and each
committee of the Board and such boards and committees of the Subsidiaries as of
the date thereof who are not employees of the Company shall remain members of
the Board and of such boards and committees.
 
     Amendments.  The Merger Agreement provides that following the election or
appointment of Parent's designees in accordance with the immediately preceding
paragraph and prior to the Effective Time, any amendment of the Merger Agreement
or the Constituent Documents of the Company, any termination of the Merger
Agreement by the Company, any extension by the Company of the time for the
performance of any of the obligations or other acts of Parent or Purchaser or
any waiver of any of the Company's rights thereunder will require the
concurrence of a majority of those directors of the Company then in office other
than directors designated by Parent or directors who are employees of the
Company or, if no such directors are then in office, no such amendment,
termination, extension or waiver shall be effected which is materially adverse
to the holders of Shares (other than Parent and its Subsidiaries).
 
     Access to Information; Confidentiality.  Pursuant to the Merger Agreement,
from the date of the Merger Agreement to the consummation of the Offer, the
Company agreed to, and to cause its Subsidiaries to, afford the officers,
employees and agents of Parent and Purchaser and persons providing or committing
to provide Parent or Purchaser with financing for the transactions contemplated
by the Merger Agreement (the "Transactions") complete access at all reasonable
times to the officers, employees, agents, properties, offices, plants and other
facilities, books and records of the Company and each Subsidiary and to furnish
Parent and Purchaser and persons providing or committing to provide Parent or
Purchaser with financing for the Transactions with all financial, operating and
other data and information as Parent or Purchaser, through its officers,
employees or agents, may reasonably request. Parent and Purchaser agreed in the
Merger Agreement to keep all such information obtained in connection with
entering into the Merger Agreement confidential in accordance with the
confidentiality agreement, dated April 25, 1997 (the "Confidentiality
Agreement"), between Parent and the Company.
 
     No Solicitation of Transactions.  The Company has agreed that neither the
Company nor any Subsidiary shall, directly or indirectly, through any officer,
director, agent or otherwise, solicit, initiate or encourage the submission of
any proposal or offer from any person relating to any acquisition or purchase of
all or any material portion of the assets of, or any equity interest in, the
Company or any Material Subsidiary or any business combination with the Company
or any Material Subsidiary or participate in any negotiations regarding, or
furnish to any other person any information with respect to, or otherwise
cooperate in any way with, or assist or participate in, facilitate or encourage,
any effort or attempt by any other person to do or seek any of the foregoing and
the Company has agreed to immediately cease and
 
                                       23
<PAGE>   26
 
cause to be terminated all existing discussions or negotiations with any parties
conducted heretofore with respect to any of the foregoing. Notwithstanding the
foregoing, the Merger Agreement permits the Board to furnish information to, or
enter into discussions or negotiations with, any person in connection with an
unsolicited (from the date of the Merger Agreement) proposal in writing by such
person to acquire the Company pursuant to a merger, consolidation, share
exchange, business combination or other similar transaction or to acquire all or
substantially all of the assets of the Company or any of its Subsidiaries, if,
and only to the extent that, (a) the Board, after consultation with independent
legal counsel (which may include its regularly engaged independent legal
counsel), determines in good faith that such action is required for the Board to
comply with its fiduciary duties to stockholders imposed by Delaware Law and (b)
prior to furnishing such information to, or entering into discussions or
negotiations with, such person, the Company uses its reasonable efforts to
obtain from such person an executed confidentiality agreement on terms no less
favorable to the Company than those contained in the Confidentiality Agreement.
Moreover, the Company agreed (x) to notify Parent promptly if any such proposal
or offer, or any inquiry or contact with any person with respect thereto, is
made and (y) not to release any third party from, or waive any provision of, any
confidentiality or, subject to the fiduciary duties of the Board, standstill
agreement to which the Company is or may become a party.
 
     Treatment of Stock Options; Deferred Director Fees.  The Merger Agreement
provides that, in accordance with the terms of the Company's Amended and
Restated Equity Incentive Plan for Key Employees, the Company's Amended and
Restated 1988 Equity Incentive Plan for Outside Directors or the Company's 1995
Equity Incentive Plan for Outside Directors (collectively, the "Stock Option
Plans"), each outstanding option to purchase Shares granted under the Company's
Stock Option Plans shall, immediately prior to the Effective Time, become
exercisable regardless of the vesting schedule contained in any stock option
agreement or in any of the Stock Option Plans and shall be canceled at the
Effective Time. In the event that any unexercised option is canceled by the
Company, each holder of a canceled option shall be entitled to receive, at the
Effective Time or as soon as practicable thereafter, from the Company, in
consideration for the cancellation of such option, an amount (subject to any
applicable withholding tax) in cash equal to the product of (a) the number of
Shares previously subject to such option and (b) the excess, if any, of the
Merger Consideration over the exercise price per Share previously subject to
such option. The Merger Agreement also provides that, at the Effective Time, the
Company shall pay to each individual who served as a director of the Company
prior to the Effective Time any and all deferred director fees owed to such
individual.
 
     Indemnification and Insurance.  Pursuant to the Merger Agreement, the
Certificate of Incorporation and Bylaws of the Surviving Corporation are
required to contain provisions no less favorable with respect to indemnification
than are set forth in Article XIII of the Bylaws of the Company, which
provisions shall not be amended, repealed or otherwise modified for a period of
six years from the Effective Time in any manner that would affect adversely the
rights thereunder of individuals who at any time from and after the date of the
Merger Agreement to and including the Effective Time were directors, officers,
employees, fiduciaries or agents (collectively "Representatives") of the Company
in respect of acts or omissions occurring at or prior to the Effective Time
(including, without limitation, the matters contemplated by the Merger
Agreement), unless such modification shall be required by law. Moreover, from
and after the Purchaser's Election Date, the Merger Agreement prohibits the
amendment, repeal or other modification of the indemnification and advancement
of expenses provisions of Article XIII of the Bylaws of the Company or the
Constituent Documents of any of its Subsidiaries in any manner that would
adversely affect the rights thereunder of individuals who at any time from and
after the date of this Agreement and to and including the Effective Time were
Representatives of the Company or any of its Subsidiaries in respect of acts or
omissions occurring at or prior to the Effective Time (including, without
limitation, the matters contemplated by the Merger Agreement), unless such
modification is required by law.
 
     The Merger Agreement also provides that prior to the Effective Time, the
Company shall and after the Effective Time, Parent and the Surviving Corporation
shall, to the fullest extent permitted under applicable law, indemnify and hold
harmless, each present and former Representative of the Company and each
Subsidiary (collectively, the "Indemnified Parties") against all costs and
expenses (including reasonable
 
                                       24
<PAGE>   27
 
attorneys' fees), judgments, fines, losses, claims, damages, liabilities and
settlement amounts paid in connection with any claim, action, suit, proceeding
or investigation (whether arising before or after the Effective Time), whether
civil, criminal, administrative or investigative, arising out of or pertaining
to any action or omission in their capacity as a Representative, whether
occurring before or after the Effective Time, for a period of six years after
the date of the Merger Agreement (and shall pay any expenses in advance of the
final disposition of any such action or proceeding to each Indemnified Party to
the fullest extent permitted under Delaware Law, and, with respect to
Indemnified Parties who are or were directors or officers of the Company, upon
receipt from the Indemnified Party to whom expenses are advanced of any
undertaking to repay such advances required under Delaware Law).
 
     Pursuant to the Merger Agreement, the Company, from and after the date of
the Merger Agreement and to and including the Effective Time, and the Surviving
Corporation, from the Effective Time until six years thereafter, each agreed to
maintain in effect, insurance coverage, if available, equivalent to that
provided by the directors' and officers' liability insurance policies currently
maintained by the Company (provided that the Surviving Corporation may
substitute therefor policies of at least the same coverage containing terms and
conditions which are not materially less favorable) with respect to matters
occurring on or prior to the Effective Time; provided, however, that in no event
shall the Surviving Corporation be required to expend more than an amount per
year equal to 250% of current annual premiums paid by the Company for such
insurance (which annual premiums the Company has represented in the Merger
Agreement to be approximately $300,000).
 
     The Merger Agreement provides that in the event the Company, Parent or the
Surviving Corporation or any of their respective successors or assigns (a)
consolidates with or merges into any other person and shall not be the
continuing or surviving corporation or entity of such consolidation or merger or
(b) transfers all or substantially all of its properties and assets to any
person, then, and in each such case, proper provision shall be made so that the
successors and assigns of the Company, Parent or the Surviving Corporation, as
the case may be, shall assume the obligations described above. The Merger
Agreement provides that the obligations described above shall survive the
Effective Time.
 
     Employee Benefits.  Pursuant to the Merger Agreement, for a period of one
year from the Effective Time, Parent has agreed to, or to cause the Company or
the Surviving Corporation to, maintain the employee benefit plans (other than
the Stock Option Plans) which the Company maintains for the benefit of, or which
are open to, a majority of the employees of the Company on the terms in effect
on the date of the Merger Agreement, or such other plans, arrangements or
programs as will provide employees with benefits that in the aggregate are
substantially equivalent to, and no less favorable than, those provided under
the employee benefit plans (other than the Stock Option Plans) as in effect on
the date of the Merger Agreement. In addition, Parent shall, or shall cause the
Surviving Corporation to, assume and agree to perform specified "Change of
Control Agreements" in the same manner and to the same extent that the Company
is required to perform such agreements. Such Change of Control Agreements
provide for payments to certain officers and other employees of the Company upon
termination of employment, diminution of responsibility or salary or other
circumstances following a change of control of the Company. If Purchaser
consummates the Offer, a change in control will occur under the Change of
Control Agreements.
 
     Provision of Funds.  Pursuant to the Merger Agreement Parent has agreed
that (a) Parent will cause the Company to be provided with sufficient funds
immediately prior to the Purchaser's Election Date, to refinance the Company's
obligations under the Company Credit Agreement, (b) from and after the
Purchaser's Election Date, Parent will cause the Company to be provided with
sufficient funds, on terms that comply with the Indenture with respect to the
Notes to satisfy the Company's obligations under Section 4.10 of the Indenture
and (c) that such funds will be provided to the Company on terms no less
favorable to the Company than those contained in the Company Credit Agreement.
 
     Representations and Warranties.  The Merger Agreement contains various
representations and warranties of the parties thereto, including representations
by the Company as to the Company's filings with the Commission, consolidated
financial statements of the Company and its Subsidiaries, the
 
                                       25
<PAGE>   28
 
absence of certain changes or events concerning the Company's business,
compliance with law and certain contracts, litigation, insurance, licenses and
permits, employee benefit plans, labor matters, ownership of assets, trademarks,
patents and copyrights, environmental matters, brokers, taxes, absence of
certain business practices and letters of credit, surety bonds and guarantees.
 
     The Company also represented in the Merger Agreement that (a) the Board, at
a meeting duly called and held on June 25, 1997, has unanimously (i) determined
that the Merger Agreement and the transactions contemplated thereby, including
each of the Offer and the Merger, are fair to and in the best interests of the
stockholders of the Company, (ii) approved and adopted the Merger Agreement and
the transactions contemplated thereby, including, without limitation, the
Merger, and such approval constitutes approval of the foregoing for purposes of
Section 203 of Delaware Law, (iii) taken all action to avoid the occurrence of a
"Distribution Date" or a "Triggering Event" (each as defined in the Rights
Agreement) with respect to the Rights and (D) recommended that the stockholders
of the Company accept the Offer and approve and adopt the Merger Agreement and
the transactions contemplated thereby, including, without limitation, the
Merger.
 
     Parent represented and warranted to the Company in the Merger Agreement,
among other things, that Parent has, or has commitments to obtain, sufficient
funds to permit Purchaser (i) to acquire all the outstanding Shares in the Offer
and the Merger and (ii) to acquire all of the Notes (and obtain all of the
related Consents) in the Note Tender Offer, written evidence of which has been
provided to the Company.
 
     Conditions to the Merger.  Under the Merger Agreement, the respective
obligations of each party to effect the Merger are subject to the satisfaction
at or prior to the Effective Time of the following conditions and only the
following conditions: (a) the Merger Agreement and the transactions contemplated
by the Merger Agreement shall have been approved and adopted by the affirmative
vote of the stockholders of the Company (unless the vote of the stockholders is
not required by Delaware Law); (b) any waiting period (and any extension
thereof) applicable to the consummation of the Merger under the HSR Act shall
have expired or been terminated; (c) no foreign, United States or state
governmental authority or other agency or commission or foreign, United States
or state court of competent jurisdiction shall have enacted, issued,
promulgated, enforced or entered any law, rule, regulation, executive order,
decree, injunction or other order (whether temporary, preliminary or permanent)
which is then in effect and has the effect of making the acquisition of Shares
by Parent or Purchaser or any affiliate of either of them or the consummation of
the Merger illegal under applicable law or otherwise restricting, preventing or
prohibiting under applicable law the consummation of the transactions
contemplated by the Merger Agreement; (d) Purchaser or its permitted assignee
shall have purchased all Shares validly tendered and not withdrawn pursuant to
the Offer; provided, however, that neither Parent nor Purchaser shall be
entitled to assert the failure of this condition if, in breach of the Merger
Agreement or the terms of the Offer, Purchaser fails to purchase any Shares
validly tendered and not withdrawn pursuant to the Offer and (e) the
Supplemental Indenture shall have been entered into and Parent or its permitted
assignee shall have purchased all Notes validly tendered and not withdrawn
pursuant to the Note Tender Offer; provided, however, that Parent shall not be
entitled to assert the failure of this condition if, in breach of the Merger
Agreement or the terms of the Note Tender Offer, Parent fails to purchase any
Notes validly tendered and not withdrawn pursuant to the Note Tender Offer.
 
     Termination.  The Merger Agreement may be terminated and the Merger and the
other transactions contemplated by the Merger Agreement may be abandoned at any
time prior to the Effective Time, notwithstanding any requisite approval and
adoption of the Merger Agreement and the transactions contemplated thereby by
the stockholders of the Company: (a) by mutual written consent duly authorized
by the Boards of Directors of Parent, Purchaser and the Company prior to
Purchaser's Election Date; (b) by Parent, Purchaser or the Company if (i) the
Effective Time shall not have occurred on or before December 31, 1997 (so long
as the party seeking such termination has not failed to fulfill any obligation
under the Merger Agreement, which failure has been the cause of, or resulted in,
the failure of the Effective Time to occur on or before such date) or (ii) any
court of competent jurisdiction in the United States or other governmental
authority shall have issued an order, decree, ruling or taken any
 
                                       26
<PAGE>   29
 
other action restraining, enjoining or otherwise prohibiting the Merger and such
order, decree, ruling or other action shall have become final and nonappealable;
(c) by Parent if (i) due to an occurrence or circumstance that would result in a
failure to satisfy any condition to the Offer or the Note Tender Offer, as
applicable, Purchaser shall have (A) failed to commence the Offer within five
business days following the date of public announcement of the execution of the
Merger Agreement, (B) failed to commence the Note Tender Offer within 10
business days following the date of public announcement of the execution of the
Merger Agreement, (C) terminated the Offer or the Note Tender Offer without
having accepted any Shares or Notes (and without having obtained related
Consents), as the case may be, for payment thereunder or (D) failed to pay for
Shares or Notes (and obtain related Consents) pursuant to the Offer or the Note
Tender Offer, as the case may be, within 90 days following the commencement
thereof; unless such action or inaction under (A), (B), (C) or (D) shall have
been caused by or resulted from the failure of Parent or Purchaser to perform in
any material respect any material covenant or agreement of either of them
contained in the Merger Agreement or the material breach by Parent or Purchaser
of any material representation or warranty of either of them contained in the
Merger Agreement or (ii) prior to the purchase of Shares pursuant to the Offer
or the Notes pursuant to the Note Tender Offer, the Board or any committee
thereof shall have withdrawn or modified in a manner adverse to Purchaser or
Parent its approval or recommendation of the Offer, the Merger Agreement, the
Merger or any other Transaction or shall have recommended another merger,
consolidation, business combination with, or acquisition of, the Company or its
assets or another tender offer or exchange offer for Shares, or shall have
resolved to do any of the foregoing; or (d) by the Company, upon approval of the
Board if (i) Purchaser shall have (A) failed to commence the Offer within five
business days following the date of public announcement of the execution of the
Merger Agreement, (B) failed to commence the Note Tender Offer within 10
business days following the date of public announcement of the execution of the
Merger Agreement, (C) terminated the Offer or the Note Tender Offer without
having accepted any Shares or Notes (and without having obtained related
Consents), as the case may be, for payment thereunder or (D) failed to pay for
Shares pursuant to the Offer or the Notes (and obtain related Consents) pursuant
to the Note Tender Offer within 90 days following the commencement thereof,
unless such action or inaction under (A), (B), (C) or (D) shall have been caused
by or resulted from the failure of the Company to perform in any material
respect any material covenant or agreement of it contained in the Merger
Agreement or the material breach by the Company of any material representation
or warranty of it contained in the Merger Agreement or (ii) prior to the
purchase of Shares pursuant to the Offer or the Notes pursuant to the Note
Tender Offer, the Board shall have withdrawn or modified in a manner adverse to
Purchaser or Parent its approval or recommendation of the Offer, the Merger
Agreement, the Merger or any other Transaction in order to approve the execution
by the Company of a definitive agreement providing for the acquisition of the
Company or any of its assets by a sale, merger or other business combination or
in order to approve a tender offer or exchange offer for Shares by a third
party, in either case, as the Board determines in good faith that such action is
required for the Board to comply with its fiduciary duties to stockholders,
after consultation with its independent legal counsel and financial advisers,
and is on terms more favorable to the Company's stockholders than the Offer and
the Merger taken together (this provision of the Merger Agreement, together with
the provision described in clause (c)(ii) of this sentence, are collectively
referred to as the "Fiduciary Out Clause"); provided, however, that such
termination under this clause (ii) shall not be effective until the Company has
made payment to Parent of the Fee (as hereinafter defined) required to be paid
pursuant to the Merger Agreement and has deposited with a mutually acceptable
escrow agent $2.0 million for reimbursement of Expenses (as hereinafter
defined).
 
     In the event of the termination of the Merger Agreement, the Merger
Agreement provides that it shall forthwith become void, and there shall be no
liability on the part of any party hereto, except under the provisions of the
Merger Agreement related to fees and expenses described below and
confidentiality and except for liability of any party for breach of the Merger
Agreement prior to its termination.
 
     Fees and Expenses.  The Merger Agreement provides that in the event that
(a) any person (including, without limitation, the Company or any affiliate
thereof), other than Parent or any affiliate of Parent, shall have become the
beneficial owner of more than 20% of the then outstanding Shares, the
 
                                       27
<PAGE>   30
 
Merger Agreement shall have been terminated (other than pursuant to the
Fiduciary Out Clause) and within 12 months of such termination a Third Party
Acquisition (as defined hereinafter) shall occur; or (b) any person shall have
commenced, publicly proposed or communicated to the Company a proposal that is
publicly disclosed for a tender or exchange offer for 25% or more of the then
outstanding shares (or which, assuming the maximum amount of securities that
could be purchased, would result in any person beneficially owning 25% or more
of the then outstanding Shares) or otherwise for the direct or indirect
acquisition of the Company or all or substantially all of its assets for per
Share consideration having a value greater than the Per Share Amount and (i) the
Offer shall have remained open for at least 20 business days, (ii) the Minimum
Condition shall not have been satisfied and (iii) the Merger Agreement shall
have been terminated (other than pursuant to the Fiduciary Out Clause) and (iv)
within 12 months of such termination a Third Party Acquisition shall occur; or
(c) if the Minimum Condition or the Requisite Consent Condition shall not have
been satisfied on or prior to the date that is 60 days from the date of
commencement of the Offer, Parent desires to extend the Offer beyond such 60 day
period but the Company declines to consent to such extension, the Merger
Agreement is terminated (other than pursuant to the Fiduciary Out Clause) and
within 12 months of such termination a Third Party Acquisition shall occur; or
(d) the Merger Agreement is terminated pursuant to the Fiduciary Out Clause,
then, in any such event, provided that neither Parent nor Purchaser is in
material breach of its obligations under the Merger Agreement, the Company shall
pay Parent promptly (but in no event later than one business day after (i) the
consummation of the Third Party Acquisition, with respect to the events
described in clauses (a), (b) or (c), or (ii) such termination with respect to
clause (d)) a fee of U.S. $8 million (the "Fee"), plus "Expenses" (as defined
below).
 
     The Merger Agreement also provides that so long as neither Parent nor
Purchaser is in material breach of its obligations under the Merger Agreement
and Parent is not entitled to the Fee pursuant to the preceding paragraph, if
(a) the Merger Agreement is terminated as described in clause (c) of the third
preceding paragraph due to the material breach of the Company's obligations
under the Merger Agreement or (b) the Merger Agreement is terminated as
described in clause (c) of the third preceding paragraph because of the
occurrence of the condition set forth in paragraph (f) under Section 14 set
forth below and such occurrence results from the failure of representations and
warranties of the Company to be true and correct in accordance with its terms,
then, in either case (a) or (b), the Company shall promptly reimburse Parent and
Purchaser for all Expenses.
 
     "Expenses" is defined in the Merger Agreement to mean all reasonable
out-of-pocket expenses and fees up to U.S. $2.0 million in the aggregate
(including, without limitation, reasonable fees and expenses payable to all
banks, investment banking firms, other financial institutions and other persons
and their respective agents and counsel for arranging, committing to provide or
providing any financing for the transactions contemplated by the Merger
Agreement or structuring such transactions and all reasonable fees of counsel,
accountants, experts and consultants to Parent and Purchaser, and all printing
and advertising expenses) actually incurred by either of them or on their behalf
in connection with the transactions contemplated by the Merger Agreement,
including, without limitation, the financing thereof, and actually incurred by
banks, investment banking firms, other financial institutions and other persons
and assumed by Parent and Purchaser in connection with the negotiation,
preparation, execution and performance of the Merger Agreement, the structuring
and financing of the transactions contemplated by the Merger Agreement and any
financing commitments or agreements relating thereto. In the event that the
Company shall fail to pay the Fee or any Expenses when due, the term "Expenses"
is deemed to include the reasonable costs and expenses actually incurred or
accrued by Parent and Purchaser (including, without limitation, fees and
expenses of counsel) in connection with the collection under and enforcement of
the fees and expenses provision of the Merger Agreement, together with interest
on such unpaid Fee and Expenses, commencing on the date that the Fee or such
Expenses became due, at a per annum rate equal to the rate of interest publicly
announced by Morgan Guaranty Trust Company of New York, from time to time, in
the City of New York, as such bank's prime rate plus 1%.
 
     "Third Party Acquisition" is defined in the Merger Agreement to mean the
occurrence of any of the following events: (i) the acquisition of the Company by
merger, consolidation or other business
 
                                       28
<PAGE>   31
 
combination transaction by any person other than Parent, Purchaser or any
affiliate thereof (a "Third Party"); (ii) the acquisition by any Third Party of
all or substantially all of the assets of the Company and its Subsidiaries,
taken as a whole; (iii) the acquisition by a Third Party of 50% or more of the
outstanding Shares whether by tender offer, exchange offer or otherwise; (iv)
the adoption by the Company of a plan of liquidation or the declaration or
payment of an extraordinary dividend; or (v) the repurchase by the Company or
any of its Subsidiaries of 50% or more of the outstanding Shares.
 
     Except as set forth above, all costs and expenses incurred by Parent,
Purchaser and the Company in connection with the Merger Agreement and the
transactions contemplated by the Merger Agreement shall be paid by the party
incurring such expenses, whether or not any such transaction is consummated.
 
     Confidentiality Agreement.  On April 25, 1997, Parent entered into a
Confidentiality Agreement with the Company. The following is a summary of the
Confidentiality Agreement, a copy of which has been filed as an Exhibit to the
Schedule 14D-1 filed by Purchaser and Parent with the Commission in connection
with the Offer. Such summary is qualified in its entirety by reference to the
Confidentiality Agreement. Under the Confidentiality Agreement, Parent agreed to
use information furnished by the Company or its representatives, compiled by
Parent or its representatives from such furnished information, or gathered by
Parent by inspection of the Company and its Subsidiaries, that is not otherwise
generally available to the public (other than as a result of disclosure by
Parent or its representatives) (the "Evaluation Materials") exclusively for the
purpose of evaluating an acquisition transaction with the Company. In addition,
Parent agreed not to disclose any of the Evaluation Materials other than under
certain circumstances. Under the Confidentiality Agreement, Parent agreed that
without the prior written consent of the Company (i) for a period of two years
from the date of the Confidentiality Agreement it would not solicit for
employment any person employed by the Company on April 25, 1997 as a key
employee and (ii) for a period of one year from the date of the Confidentiality
Agreement it would not, (A) acquire or make any proposal to acquire any
securities or property of the Company, (B) propose to enter into any merger or
business combination involving the Company or purchase a material portion of the
assets of the Company, (C) make or participate in any solicitation of proxies to
vote, or seek to advise or influence any person with respect to the voting of
any securities of the Company, (D) form, join or participate in a "group"
(within the meaning of Section 13(d)(3) of the Exchange Act) with respect to any
voting securities of the Company, (E) otherwise act to seek to control or
influence the management, the Board of policies of the Company, (F) disclose any
intention, plan or arrangement inconsistent with the foregoing, or (G) take any
action which might require the Company to make a public announcement regarding
the possibility of a business combination or merger. Assuming the Minimum
Condition has been satisfied, upon acceptance for payment of Shares pursuant to
the Offer, the Confidentiality Agreement shall be deemed to have been terminated
without further action by the parties thereunder.
 
     Exclusivity Agreement.  The following is a summary of the Exclusivity
Agreement, dated as of June 16, 1997, between Parent and the Company (the
"Exclusivity Agreement"), a copy of which has been filed as an Exhibit to the
Schedule 14D-1 filed by Purchaser and Parent with the Commission in connection
with the Offer. Such summary is qualified in its entirety by reference to the
Exclusivity Agreement. The Exclusivity Agreement provided that, from June 16,
1997 through June 30, 1997 (the "Due Diligence Period"), the Company would
provide Parent access for a due diligence review of the Company and Parent and
the Company would work diligently in good faith towards the preparation and
execution of a definitive merger agreement (subject to Parent's satisfactory
completion of its due diligence review).
 
     In the Exclusivity Agreement, the Company also agreed that it would not,
and no director, officer, stockholder, employee, agent or other representative
of the Company would be authorized by the Company to, negotiate or solicit
proposals for the sale or other disposition of the Company or its assets
(whether by means of a negotiated sale of securities or assets, tender or
exchange offer, merger or other business combination, recapitalization,
restructuring or other transaction (any such transaction being referred to as a
"Sale")) with or from any other party during the Due Diligence Period; provided,
however that the obligation described above would have terminated at 5:00 p.m.,
New York time on June 25,
 
                                       29
<PAGE>   32
 
1997, if Parent had not notified the Company by that time that its board of
directors had determined to proceed with a business combination transaction. In
addition, the Company agreed that it would immediately cease and cause to be
terminated during such Due Diligence Period any existing activities, discussions
or negotiations with any person other than Parent or its affiliates in respect
of a Sale. In the event the Company received an unsolicited offer (an "Other
Offer") during the Due Diligence Period and was advised in writing by its legal
counsel that its board of directors had a fiduciary obligation to consider and
respond to such Other Offer prior to the expiration of the Due Diligence Period,
the Exclusivity Agreement permitted the Company to do so provided it advised
Parent of the receipt of such Other Offer and allowed Parent to submit a
competing offer for consideration by the Board at the same meeting at which such
Other Offer was to be considered. In consideration of the Company's agreement
described in this paragraph, Parent agreed to diligently pursue its review of
the Company during the Due Diligence Period and agreed further to notify the
Company within twenty-four (24) hours of any determination to not proceed with a
business combination transaction as contemplated by the parties, whereupon the
provisions described in this paragraph would terminate.
 
     In the Exclusivity Agreement, the Company and Parent also agreed to keep
confidential all matters related to a proposed transaction with the Company
(except as required by law) and the Company expressed its intent to call a
meeting of its Board to consider a proposed transaction with Parent prior to the
end of the Due Diligence Period. The terms of the Exclusivity Agreement were
superseded by the Merger Agreement.
 
     11. PURPOSE OF THE OFFER; PLANS FOR THE COMPANY AFTER THE OFFER AND THE
MERGER.
 
     Purpose of the Offer.  The purpose of the Offer and the Merger is for
Parent to acquire control of, and the entire equity interest in, the Company.
Upon consummation of the Merger, the Company will become an indirect wholly
owned subsidiary of Parent. The Offer is being made pursuant to the Merger
Agreement.
 
     In the Merger Agreement, the Company has agreed, in the event the
affirmative vote of the holders of Shares is required to approve the Merger
under Delaware Law or the Company's Certificate of Incorporation, to take all
action necessary to convene a meeting of its stockholders as soon as practicable
after the consummation of the Offer for the purpose of considering and taking
action on the Merger Agreement and the transactions contemplated thereby. Parent
and Purchaser have agreed that all Shares owned by them and their subsidiaries
will be voted in favor of the Merger Agreement and the transactions contemplated
thereby.
 
     If Purchaser purchases Shares pursuant to the Offer, the Merger Agreement
provides that Parent shall be entitled to designate representatives to serve on
the Company's Board of Directors in proportion to Purchaser's ownership of
Shares following such purchase. See Section 10. Purchaser expects that such
representation would permit Purchaser to exert substantial influence over the
Company's conduct of its business and operations.
 
     Appraisal Rights; Going Private Transactions.  No appraisal rights are
available in connection with the Offer. However, if the Merger is consummated,
stockholders will have certain rights under Delaware Law to dissent and demand
appraisal of, and to receive payment in cash of the fair value of, their Shares.
Such rights to dissent, if the statutory procedures are complied with, could
lead to a judicial determination of the fair value of the Shares, as of the
Effective Time (excluding any element of value arising from the accomplishment
or expectation of the Merger), required to be paid in cash to such dissenting
holders for their Shares. In addition, such dissenting stockholders could be
entitled to receive payment of a fair rate of interest from the date of
consummation of the Merger on the amount determined to be the fair value of
their Shares. In determining the fair value of the Shares, the court is required
to take into account all relevant factors. Accordingly, such determination could
be based upon considerations other than, or in addition to, the market value of
the Shares, including, among other things, asset values and earnings capacity.
In Weinberger v. UOP, Inc., the Delaware Court stated among other things, that
"proof of value by any techniques or methods which are generally considered
acceptable in the financial community and otherwise admissable in court" should
be considered in an appraisal proceeding. Therefore, the value so
 
                                       30
<PAGE>   33
 
determined in any appraisal proceeding could be the same, more or less than the
purchase price per Share in the Offer or the Merger Consideration.
 
     In addition, several decisions by Delaware courts have held that, in
certain circumstances, a controlling stockholder of a company involved in a
merger has a fiduciary duty to other stockholders which requires that the merger
be fair to such other stockholders. In determining whether a merger is fair to
minority stockholders, Delaware courts have considered, among other things, the
type and amount of consideration to be received by the stockholders and whether
there was fair dealing among the parties. The Delaware Supreme Court stated in
Weinberger v. Philip A. Hunt Chemical Corp. that the remedy ordinarily available
to minority stockholders in a cash-out merger is the right to appraisal
described above. However, a damage remedy or injunctive relief may be available
if a merger is found to be the product of unfairness, including fraud,
misrepresentation or other misconduct.
 
     The Commission 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 Purchaser seeks
to acquire the remaining Shares not held by it. Purchaser believes, however,
that if the Merger is consummated within one year of the purchase of Shares
pursuant to the Offer, Rule 13e-3 will not be applicable to the Merger.
Purchaser believes that if the Merger is not consummated within one year of its
purchase of Shares pursuant to the Offer, Rule 13e-3 may be applicable to the
Merger. 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
stockholders in such transaction be filed with the Commission and disclosed to
stockholders prior to consummation of the transaction.
 
     Plans for the Company.  It is currently expected that, following
consummation of the Offer, initially the business and operations of the Company
will, except as set forth in this Offer to Purchase, be continued by the Company
substantially as they are currently being conducted. Parent will continue to
evaluate the business and operations of the Company during the pendency of the
Offer and after the consummation of the Offer and the Merger, and will take such
actions as it deems appropriate under the circumstances then existing. Parent
intends to seek additional information about the Company during this period.
Thereafter, Parent intends to review such information as part of a comprehensive
review of the Company's business, operations, capitalization and management with
a view to maximizing the Company's potential in conjunction with Parent's
businesses. It is expected that the business and operations of the Company would
form an important part of Parent's future business plans.
 
     Except as indicated in this Offer to Purchase, Parent does not have any
present plans or proposals that relate to or would result in an extraordinary
corporate transaction, such as a merger, reorganization or liquidation,
involving the Company or any Subsidiary, a sale or transfer of a material amount
of assets of the Company or any Subsidiary or any material change in the
Company's capitalization or dividend policy or any other material changes in the
Company's corporate structure or business, or the composition of the Board or
the Company's management.
 
     12. DIVIDENDS AND DISTRIBUTIONS.  The Merger Agreement provides that the
Company shall not, between the date of the Merger Agreement and the Effective
Time, without the prior written consent of Parent, (a) issue, sell, pledge,
dispose of, grant, encumber, or authorize the issuance, sale, pledge,
disposition, grant or encumbrance of any shares of capital stock of any class of
the Company or any Subsidiary, or any options, warrants, convertible securities
or other rights of any kind to acquire any shares of such capital stock, or any
other ownership interest (including, without limitation, any phantom interest),
of the Company or any Subsidiary (except for the issuance of a maximum of
2,000,000 Shares issuable pursuant to employee stock options outstanding on the
date of the Merger Agreement and including up to 1,250 restricted Shares per
quarter issuable to outside directors in accordance with past practice pursuant
to the Stock Option Plans), (b) declare, set aside, make or pay any dividend or
other distribution, payable in cash, stock, property or otherwise, with respect
to any of its capital stock, except for such declarations, set asides, dividends
and other distributions made by any Subsidiary to the Company or (c) reclassify,
combine, split, subdivide or redeem, purchase or otherwise acquire, directly
 
                                       31
<PAGE>   34
 
or indirectly, any of its capital stock. See Section 10. If, however, the
Company should, during the pendency of the Offer, (i) split, combine or
otherwise change the Shares or its capitalization, (ii) acquire or otherwise
cause a reduction in the number of outstanding Shares or (iii) issue or sell any
additional Shares (other than pursuant to outstanding employee and director
options, shares of any other class or series of capital stock, other voting
securities or any securities convertible into, or options, rights, or warrants,
conditional or otherwise, to acquire, any of the foregoing, then, without
prejudice to Purchaser's rights under Section 14, Purchaser may (subject to the
provisions of the Merger Agreement) make such adjustments to the purchase price
and other terms of the Offer (including the number and type of securities to be
purchased) as it deems appropriate to reflect such split, combination or other
change, acquisition, reduction, issuance or sale.
 
     If, on or after June 23, 1997, the Company should declare or pay any
dividend on the Shares or make any other distribution (including the issuance of
additional shares of capital stock pursuant to a stock dividend or stock split,
the issuance of other securities or the issuance of rights for the purchase of
any securities) with respect to the Shares that is payable or distributable to
stockholders of record on a date prior to the transfer to the name of Purchaser
or its nominee or transferee on the Company's stock transfer records of the
Shares purchased pursuant to the Offer then, without prejudice to Purchaser's
rights under Section 14, (i) the purchase price per Share payable by Purchaser
pursuant to the Offer will be reduced (subject to the Merger Agreement) to the
extent any such dividend or distribution is payable in cash and (ii) any
non-cash dividend, distribution or right shall be received and held by the
tendering stockholder for the account of Purchaser and will be required to be
promptly remitted and transferred by each tendering stockholder to the
Depositary for the account of Purchaser, accompanied by appropriate
documentation of transfer. Pending such remittance and subject to applicable
law, Purchaser will be entitled to all the rights and privileges as owner of any
such non-cash dividend, distribution or right and may withhold the entire
purchase price or deduct from the purchase price the amount or value thereof, as
determined by Purchaser in its sole discretion.
 
     13. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES, NYSE LISTING AND
EXCHANGE ACT REGISTRATION.  The purchase of Shares by Purchaser pursuant to the
Offer will reduce the number of Shares that might otherwise trade publicly and
will reduce the number of holders of Shares, which could adversely affect the
liquidity and market value of the remaining Shares held by the public.
 
     Depending upon the number of Shares purchased pursuant to the Offer, the
Shares may no longer meet the requirements of the New York Stock Exchange for
continued listing and may be delisted from the New York Stock Exchange and
deregistered under Section 12(b) of the Exchange Act. Parent intends to cause
the delisting by the New York Stock Exchange and deregistration of the Shares
following consummation of the Offer.
 
     According to published guidelines, the New York Stock Exchange would
consider delisting the Shares if, among other things, the number of holders of
Shares should fall below 400 (or below 1,200, if trading volume falls below
100,000 Shares for the most recent 12 months), the number of publicly held
Shares (exclusive of holdings of officers, directors and their families and
other concentrated holdings of 10 percent or more ("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 $8,000,000. The Company
has advised Purchaser that, as of June 24, 1997, there were 17,126,609 Shares
outstanding, held by approximately 18,000 holders of record. If, as a result of
the purchase of Shares pursuant to the Offer or otherwise, the Shares no longer
meet the requirements of the New York Stock Exchange for continued listing and
the listing of the Shares is discontinued, the market for the Shares could be
adversely affected.
 
     If the New York Stock Exchange 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 Stock Market ("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 stockholders 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
 
                                       32
<PAGE>   35
 
securities firms, the possible termination of registration under the Exchange
Act as described below, and other factors. 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 greater or less than
the Merger Consideration.
 
     The Shares are currently "margin securities," as such term is defined under
the rules of the Board of Governors of the Federal Reserve System (the "Federal
Reserve Board"), which has the effect, among other things, of allowing banks to
extend credit on the collateral of such securities. Depending upon factors
similar to those described above regarding listing and market quotations,
following the Offer it is possible that the Shares might no longer constitute
"margin securities" for purposes of the margin regulations of the Federal
Reserve Board, in which event such Shares might no longer be eligible as
collateral for loans made by banks.
 
     The Shares are currently registered under the Exchange Act. Registration of
the Shares under the Exchange Act may be terminated upon application of the
Company to the Commission if the Shares are not listed on a national securities
exchange and there are fewer than 300 record holders of the Shares. Termination
of registration of the Shares under the Exchange Act, assuming there are no
other securities of the Company subject to registration, would substantially
reduce the information required to be furnished by the Company to its
stockholders and to the Commission 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
stockholders' 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 Company. Furthermore, if the Purchaser acquires a
substantial number of Shares, the ability of "affiliates" of the Company and
persons holding "restricted securities" of the Company to dispose of such
securities pursuant to Rule 144 or 144A promulgated under the Securities Act of
1933, as amended, may be impaired or eliminated. If registration of the Shares
under the Exchange Act were terminated, the Shares would no longer be "margin
securities" or be eligible for NASDAQ reporting.
 
     It is the present intention of the Parent 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. If registration of the Shares under the
Exchange Act is not terminated prior to the Merger, registration of the Shares
under the Exchange Act will be terminated following the consummation of the
Merger.

     the Board or any committee thereof shall have resolved to do any of the

                                       34
<PAGE>   37
 
          (f) (i) any representation or warranty of the Company in the Merger
     Agreement shall not be true and correct; or
 
             (ii) there shall have occurred, since the date of the Merger
        Agreement, a change in the business, operations, financial condition,
        assets or liabilities of the Company or any Subsidiary
 
     with the effect that such failure of any such representation or warranty to
     be true and correct or such change, when taken together with all other such
     failures of such representations and warranties to be true and correct
     (both favorable and adverse) and all other such changes (both favorable and
     adverse), in the aggregate would have, a Material Adverse Effect; provided,
     however that, for the purpose of the foregoing condition, in determining
     whether any such representation or warranty is true or correct, any
     qualification as to materiality or Material Adverse Effect contained in any
     such representation and warranty shall be deemed not to apply;
 
          (g) the Company shall have failed to perform in any material respect
     any material obligation or to comply in any material respect with any
     material agreement or material covenant of the Company to be performed or
     complied with by it under the Merger Agreement;
 
          (h) the Merger Agreement shall have been terminated in accordance with
     its terms; or
 
          (i) Purchaser and the Company shall have agreed that Purchaser shall
     terminate the Offer or postpone the acceptance for payment of or payment
     for Shares thereunder; which, in the sole judgment of Purchaser, in any
     such case, and regardless of the circumstances (including any action or
     inaction by Parent or any of its affiliates) giving rise to any such
     condition, makes it inadvisable to proceed with such acceptance for payment
     or payment.
 
     The foregoing conditions are for the sole benefit of Purchaser and Parent
and may be asserted by Purchaser or Parent regardless of the circumstances
giving rise to any such condition or may be waived by Purchaser or Parent in
whole or in part at any time and from time to time in their sole discretion. The
failure by Parent or Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right; the waiver of any such
right with respect to particular facts and other circumstances shall not be
deemed a waiver with respect to any other facts and circumstances; and each such
right shall be deemed an ongoing right that may be asserted at any time and from
time to time.

not be required to accept for payment or pay for any Notes or related Consents

     directly or indirectly restrain or prohibit or make materially more costly
     the making of the Note Tender Offer, the acceptance for payment of, or
     payment for, any Notes or related Consents by Parent or any other affiliate
     of Parent pursuant to the Note Tender Offer or the consummation of any
     other Transaction, or seeking to obtain material damages in connection with
     any Transaction; (ii) seeking to prohibit or limit materially the ownership
     or operation by the Company or Parent of all or any material portion of its
     business or to compel the Company or Parent to dispose of or hold separate

     any court or governmental, administrative or regulatory authority or
     agency, domestic or foreign, resulting from any action or proceeding
     brought by any person other than any governmental, administrative or
     regulatory authority or agency, domestic or foreign, that (i) restrains or

     other Transaction; (ii) prohibits or limits ownership or operation by the
     Company or Parent of all or any material portion of its business or assets
     or compels the Company or Parent to dispose of or hold separate all or any
     material portion of its business or assets, in each case as a result of the
     Transactions; (iii) imposes limitations on the ability of Parent or

     any committee thereof shall have withdrawn or modified in a manner adverse
     to Parent or Purchaser the approval or recommendation of the Offer, the
     Merger or the Agreement or approved or recommended any takeover proposal or

     the Board or any committee thereof shall have resolved to do any of the
     foregoing;
 
          (f) (i) any representation or warranty of the Company in the Merger
     Agreement shall not be true and correct; or
 
          (ii) there shall have occurred, since the date of the Merger
     Agreement, a change in the business, operations, financial condition,

     be true and correct or such change, when taken together with all other such
     failures of such representations and warranties to be true and correct
     (both favorable and adverse) and all other such changes (both favorable and
     adverse), in the aggregate would have, a Material Adverse Effect; provided,
     however that, for the purpose of the foregoing condition, in determining
     whether any such representation or warranty is true or correct, any
     qualification as to materiality or Material Adverse Effect contained in any
     such representation and warranty shall be deemed not to apply;

          (g) the Company shall have failed to perform in any material respect
     any material obligation or to comply in any material respect with any
     material agreement or material covenant of the Company to be performed or
     complied with by it under the Agreement;
 
          (h) the Merger Agreement shall have been terminated in accordance with
     its terms; or
 
          (i) Purchaser and the Company shall have agreed that Purchaser shall
     terminate the Note Tender Offer or postpone the acceptance for payment of
     or payment for Notes and related Consents thereunder; which, in the sole
     judgment of Purchaser, in any such case, and regardless of the
     circumstances (including any action or inaction by Parent or any of its
     affiliates) giving rise to any such condition, makes it inadvisable to
     proceed with such acceptance for payment or payment.
 
     The foregoing conditions are for the sole benefit of Purchaser and Parent
and may be asserted by Purchaser or Parent regardless of the circumstances
giving rise to any such condition or may be waived by Purchaser or Parent in
whole or in part at any time and from time to time in their sole discretion. The
failure by Parent or Purchaser at any time to exercise any of the foregoing
rights shall not be deemed a waiver of any such right; the waiver of any such
right with respect to particular facts and other circumstances shall not be
deemed a waiver with respect to any other facts and circumstances; and each such
right shall be deemed an ongoing right that may be asserted at any time and from
time to time.
 
     15. CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS.
 
     General.  Based upon its examination of publicly available information with
respect to the Company and the review of certain information furnished by the
Company to Parent and discussions of representatives of Parent with
representatives of the Company during Parent's investigation of the Company (see
Section 10), neither Purchaser nor Parent is aware of any license or other
regulatory permit that appears to be material to the business of the Company and
the Subsidiaries, taken as a whole, that might be adversely affected by the
acquisition of Shares by Purchaser pursuant to the Offer or, except as set forth
below, of any approval or other action by any domestic (federal or state) or
foreign governmental, administrative or regulatory authority or agency that
would be required prior to the acquisition of Shares by Purchaser pursuant to
the Offer. Should any such approval or other action be required, it is
Purchaser's present intention to seek such approval or action. Purchaser does
not currently intend, however, to delay the purchase of Shares tendered pursuant
to the Offer pending the outcome of any such action or the receipt of any such
approval (subject to Purchaser's right to decline to purchase Shares if any of
the conditions in Section 14 shall have occurred). There can be no assurance
that any such approval or other action, if needed, would be obtained without
substantial conditions or that adverse consequences might not result to the
business of the Company, Purchaser or Parent (or that certain parts of the
businesses of the Company, Purchaser or Parent might not have to be disposed of
or held separate, or other substantial conditions complied with) in order to
obtain such approval or other action or in the event that such approval was not
obtained or such other action was not taken. 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 Laws; Antitakeover Provisions in Certificate of
Incorporation.  Under Delaware law, the approval of the Board and the
affirmative vote of the holders of a majority of the outstanding Shares are
required to approve and adopt the Merger, except that the affirmative vote of
the holders of Shares will not be required if immediately prior to the Effective
Time Purchaser holds 90 percent or more of the outstanding Shares. The Company
has represented to Parent and Purchaser in the Merger Agreement that prior to
the execution and delivery of the Merger Agreement and the Stockholders
Agreement by the parties thereto, the Company's Board approved the transactions
contemplated thereby such that the Merger shall not be subject to restrictions
under Section 203 of Delaware Law.
 
     A number of other states have adopted laws and regulations applicable to
attempts to acquire securities of corporations that are incorporated, or have
substantial assets, stockholders, principal executive offices or principal
places of business, or whose business operations otherwise have substantial
economic effects, in such states. In Edgar v. MITE Corp., the Supreme Court of
the United States
 
                                       37
<PAGE>   40
 
invalidated on constitutional grounds the Illinois Business Takeover Statute,
which, as a matter of state securities law, made takeovers of corporations
meeting certain requirements more difficult. However, in 1987 in CTS Corp. v.
Dynamics Corp. of America, the Supreme Court held that the State of Indiana
could, as a matter of corporate law and, in particular, with respect to those
aspects of corporate law concerning corporate governance, constitutionally
disqualify a potential acquiror from voting on the affairs of a target
corporation without the prior approval of the remaining stockholders. The state
law before the Supreme Court was by its terms applicable only to corporations
that had a substantial number of stockholders in the state and were incorporated
there. Subsequently, in TLX Acquisition Corp. v. Telex Corp., a federal district
court in Oklahoma ruled that certain Oklahoma corporate governance statutes were
unconstitutional insofar as they applied to corporations incorporated outside
Oklahoma because they could subject such corporations to inconsistent
regulations. Similarly, in Tyson Foods, Inc. v. McReynolds, a federal district
court in Tennessee ruled that four Tennessee takeover statutes were
unconstitutional as applied to corporations incorporated outside Tennessee. This
decision was affirmed by the United States Court of Appeals for the Sixth
Circuit. In December 1988, a federal district court in Florida held in Grand
Metropolitan PLC v. Butterworth that the provisions of the Florida Affiliated
Transactions Act and the Florida Control Share Acquisition Act were
unconstitutional as applied to corporations incorporated outside of Florida.
 
     The Company, directly or through subsidiaries, conducts business in a
number of states throughout the United States, some of which have enacted
takeover laws such as those described above. Purchaser does not know whether any
of these laws will, by their terms, apply to the Offer or the Merger and has not
necessarily complied with any such laws. Should any person seek to apply any
state takeover law, Purchaser will take such action as then appears desirable,
which may include challenging the validity or applicability of any such statute
in appropriate court proceedings. In the event it is asserted that one or more
state takeover laws are applicable to the Offer or the Merger, and an
appropriate court does not determine that it is inapplicable or invalid as
applied to the Offer, Purchaser might be required to file certain information
with, or receive approvals from, the relevant state authorities. In addition, if
enjoined, Purchaser might be unable to accept for payment any Shares tendered
pursuant to the Offer, or be delayed in continuing or consummating the Offer and
the Merger. In such case, Purchaser may not be obligated to accept for payment
any Shares tendered. See Section 14.
 
     Section 203 of Delaware Law limits the ability of a Delaware corporation to
engage in business combinations with "interested stockholders" (defined as any
beneficial owner of 15% or more of outstanding voting stock of the corporation)
unless, among other things, the corporation's board of directors has given its
prior approval to either the business combination or the transaction which
resulted in the stockholder becoming an "interested stockholder." The Company
has approved, among other things, the Offer and the Merger for purposes of
Section 203 of Delaware Law.
 
     Article Ten of the Company's Certificate of Incorporation provides that,
except as described below, the affirmative vote of not less than a majority of
the votes entitled to be cast by the holders of all the then outstanding shares
of voting stock of the Company, excluding voting stock beneficially owned by any
entity who has announced or publicly disclosed a plan to become the beneficial
owner of twenty percent of the voting stock of the Company (an "Interested
Stockholder"), is required to approve a "Business Combination" (defined to
include, among other things, any merger of the Company with any Interested
Stockholder or any agreement providing for such a merger). However, the vote
requirement does not apply if either (a) the merger is approved by a majority of
the "Continuing Directors" then in office or (2) certain price and procedural
requirements are met. The term "Continuing Directors" is defined to include any
director of the Company who is not an affiliate, associate or representative of
the Interested Stockholder and who was a member of the Board prior to the time
that the Interested Stockholder became an Interested Stockholder, and any
successor who is not an affiliate, associate or representative of the Interested
Stockholder and is recommended or elected to succeed a Continuing Director by a
majority of the Continuing Directors then in office. The Company has represented
in the Merger Agreement that the Board, at a meeting duly called and held on
June 25, 1997, has unanimously
 
                                       38
<PAGE>   41
 
approved and adopted the Merger Agreement and the transactions contemplated
thereby. Such approval satisfies the requirements of Article Ten of the
Company's Certificate of Incorporation.
 
     Antitrust.  Under the HSR Act and the rules that have been promulgated
thereunder by the FTC, certain acquisition transactions may not be consummated
unless certain information has been furnished to the Antitrust Division and the
FTC and certain waiting period requirements have been satisfied. The acquisition
of Shares by Purchaser pursuant to the Offer is subject to such requirements.
See Section 2.
 
     Pursuant to the HSR Act, on July 7, 1997, Parent anticipates filing a
Premerger Notification and Report Form in connection with the purchase of Shares
pursuant to the Offer with the Antitrust Division and the FTC. Under the
provisions of the HSR Act applicable to the Offer, the purchase of Shares
pursuant to the Offer may not be consummated until the expiration of a
15-calendar day waiting period following the filing by Parent. Accordingly, it
is anticipated that the waiting period under the HSR Act applicable to the
purchase of Shares pursuant to the Offer will expire at 11:59 p.m., New York
City time, on July 22, 1997, unless such waiting period is earlier terminated by
the FTC and the Antitrust Division or extended by a request from the FTC or the
Antitrust Division for additional information or documentary material prior to
the expiration of the waiting period. Pursuant to the HSR Act, Parent will
request early termination of the waiting period applicable to the Offer. There
can be no assurance, however, that the 15-day HSR Act waiting period will be
terminated early. If either the FTC or the Antitrust Division were to request
additional information or documentary material from Parent with respect to the
Offer, the waiting period with respect to the Offer 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. Thereafter, the waiting period could be
extended only by court order. If the acquisition of Shares is delayed pursuant
to a request by the FTC or the Antitrust Division for additional information or
documentary material pursuant to the HSR Act, the Offer, subject to the terms of
the Merger Agreement, may, but need not, be extended and, in any event, the
purchase of and payment for Shares will be deferred until 10 days after the
request is substantially complied with, unless the extended period expires on or
before the date when the initial 15-day period would otherwise have expired, or
unless the waiting period is sooner terminated by the FTC and the Antitrust
Division. Only one extension of such waiting period pursuant to a request for
additional information is authorized by the HSR Act and the rules promulgated
thereunder, except by court order. It is a condition to the Offer that the
waiting period applicable under the HSR Act to the Offer expire or be
terminated. See Section 2 and Section 14.
 
     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as the proposed acquisition of Shares by
Purchaser pursuant to the Offer. At any time before or after the purchase of
Shares pursuant to the Offer by Purchaser, the FTC or the Antitrust Division
could take such action under the antitrust laws as it deems necessary or
desirable in the public interest, including seeking to enjoin the purchase of
Shares pursuant to the Offer or seeking the divestiture of Shares purchased by
Purchaser or the divestiture of substantial assets of Parent, the Company or
their respective subsidiaries. Private parties and state attorneys general may
also bring legal action under federal or state antitrust laws under certain
circumstances. Based upon an examination of information available to Parent
relating to the businesses in which Parent, the Company and their respective
subsidiaries are engaged, Parent and Purchaser believe that the Offer will not
violate the antitrust laws. Nevertheless, there can be no assurance that a
challenge to the Offer on antitrust grounds will not be made or, if such a
challenge is made, what the result would be. See Section 14 for certain
conditions to the Offer, including conditions with respect to litigation.
 
     Federal Reserve Board Regulations.  The margin regulations promulgated by
the Federal Reserve Board place restrictions on the amount of credit that may be
extended for the purpose of purchasing margin stock (including the Shares) if
such credit is secured directly or indirectly by margin stock. Parent and
Purchaser believe that the financing of the acquisition of the Shares will be in
full compliance with or not subject to the margin regulations.
 
     Other Foreign Approvals.  The Company owns property and conducts business
in a number of foreign countries and jurisdictions. In connection with the
acquisition of the Shares pursuant to the Offer,
 
                                       39
<PAGE>   42
 
the laws of certain of those foreign countries and jurisdictions may require the
filing of information with, or the obtaining of the approval of, governmental
authorities in such countries and jurisdictions. The governments in such
countries and jurisdictions might attempt to impose additional conditions on the
Company's operations conducted in such countries and jurisdictions as a result
of the acquisition of the Shares pursuant to the Offer or the Merger. There can
be no assurance that Purchaser will be able to cause the Company or its
subsidiaries to satisfy or comply with such laws or that compliance or non-
compliance will not have adverse consequences for the Company or any subsidiary
after purchase of the Shares pursuant to the Offer or the Merger.
 
     16. FEES AND EXPENSES.  Neither Purchaser nor Parent, nor any officer,
director, stockholder, agent or other representative of Purchaser or Parent will
pay any fees or commissions to any broker, dealer or other person (other than
the Dealer Managers, the Information Agent and the Depositary) for soliciting
tenders of Shares pursuant to the Offer. Brokers, dealers, commercial banks and
trust companies and other nominees will, upon request, be reimbursed by
Purchaser for customary mailing and handling expenses incurred by them in
forwarding materials to their customers.
 
     Goldman Sachs and Union Bancaire are acting as Dealer Managers in
connection with the Offer and Union Bancaire has provided certain financial
advisory services to Parent and Purchaser in connection with the Offer. Parent
has agreed to pay Goldman Sachs and Union Bancaire reasonable and customary
compensation for such services. In addition, Parent has agreed to reimburse
Goldman Sachs and Union Bancaire for reasonable out-of-pocket expenses related
to their engagement, including the reasonable fees and expenses of a single
counsel, and has agreed to indemnify each of Goldman Sachs and Union Bancaire
and certain affiliated persons against certain liabilities and expenses in
connection with its services, including, without limitation, certain liabilities
under the federal securities laws.
 
     Purchaser and Parent have retained MacKenzie Partners, Inc. as the
Information Agent and First Chicago Trust Company of New York as the Depositary
in connection with the Offer. The Information Agent may contact holders of
Shares by mail, telephone, telex, telecopy, telegraph and personal interview and
may request banks, brokers, dealers and other nominee stockholders to forward
materials relating to the Offer to beneficial owners.
 
     As compensation for acting as Information Agent in connection with the
Offer, MacKenzie Partners, Inc. will be paid reasonable and customary
compensation for its services, and will also be reimbursed for certain
out-of-pocket expenses and will be indemnified against certain liabilities and
expenses in connection with the Offer, including certain liabilities under the
federal securities laws. Purchaser will pay the Depositary reasonable and
customary compensation for its services in connection with the Offer, plus
reimbursement for out-of-pocket expenses, and will indemnify the Depositary
against certain liabilities and expenses in connection therewith, including
under the federal securities laws.
 
     17. MISCELLANEOUS.  The Offer is made only by this Offer to Purchase and
the related Letter of Transmittal and is not being made to (nor will tenders be
accepted from or on behalf of) holders of Shares in any jurisdiction in which
the Offer or the acceptance thereof would not be in compliance with the
securities, blue sky or other laws of such jurisdiction. However, 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 laws require the Offer to
be made by a licensed broker or dealer, the Offer shall be deemed to be made on
behalf of Purchaser by Goldman Sachs, Union Bancaire or one or more registered
brokers or dealers licensed under the laws of such jurisdiction.
 
     NO PERSON HAS BEEN AUTHORIZED TO GIVE ANY INFORMATION OR MAKE ANY
REPRESENTATION ON BEHALF OF PURCHASER, PARENT OR THE COMPANY 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.

     Pursuant to Rule 14d-3 of the General Rules and Regulations under the
Exchange Act, Parent and Purchaser have filed with the Commission the Schedule
14D-1, together with exhibits, furnishing certain additional information with
respect to the Offer. The Schedule 14D-1 and any amendments thereto, including
exhibits, may be inspected at, and copies may be obtained from, the same places
and in the same manner as set forth in Section 7 (except that they will not be
available at the regional offices of the Commission).

    The undersigned hereby irrevocably appoints Richard A. Bearse and Richard L.
Magee, 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 or her 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 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 stockholders 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 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 Purchaser's acceptance of such
Shares for payment, Purchaser must be able to exercise full voting and other
rights with respect to such Shares and all Distributions, 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 Purchaser, 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 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 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, 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 Purchaser in its sole
discretion.
    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. Purchaser's acceptance of such Shares for payment
will constitute a binding agreement between the undersigned and 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

purchase price of all Shares purchased and all Share Certificates evidencing

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
person(s) so indicated. The undersigned recognizes that Purchaser has no
obligation, pursuant to the Special Payment Instructions, to transfer any Shares
from the name of the registered holder(s) thereof if 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.  All signatures on this Letter of Transmittal
must be medallion guaranteed by a firm that is a member of the New York Stock
Exchange Medallion Signature Guarantee Program, or by any other "eligible
guarantor institution", as such term is defined in Rule 17Ad-15 under the
Securities Exchange Act of 1934, as amended (each of the foregoing being
referred to as an "Eligible Institution"), unless (i) this Letter of Transmittal
is signed by the registered holder(s) of the Shares (which term, for purposes of
this document, shall include any participant in a Book-Entry Transfer Facility
whose name appears on a security position listing as the owner of Shares)
tendered hereby and such holder(s) has (have) completed neither the box entitled
"Special Payment Instructions" nor the box entitled "Special Delivery
Instructions" on the reverse hereof or (ii) 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 either if Share Certificates are to be forwarded
herewith or, unless an Agent's Message is utilized, 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 a 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 an Agent's Message in the case of a book-entry delivery, 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 1 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. Stockholders 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
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 a 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 delivery, 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 METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, SHARE CERTIFICATES
AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK-ENTRY
TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER, 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 stockholders 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 STOCKHOLDERS WHO TENDER BY
BOOK-ENTRY TRANSFER).  If fewer than all of the Shares evidenced by any Share
Certificate delivered to the Depositary herewith are to be tendered hereby, fill
in the number of Shares that 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.
<PAGE>   7
 
     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.
 
     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 Purchaser of such person's authority so to act must be
submitted.
 
     6.  STOCK TRANSFER TAXES.  Except as otherwise provided in this Instruction
6, 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
person or otherwise) payable on account of the transfer to such other person
will be deducted from the purchase price of such Shares purchased, unless
evidence satisfactory to Purchaser of the payment of such taxes, or exemption
therefrom, is submitted. Except as provided in this Instruction 6, it will not
be necessary for transfer tax stamps to be affixed to the Share Certificates
evidencing the Shares tendered hereby.
 
     7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS.  If a check for the purchase
price of any Shares tendered hereby is to be issued, or Share Certificate(s)
evidencing Shares not tendered or not purchased are to be issued, in the name of
a person other than the person(s) signing this Letter of Transmittal or if such
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
Letter of Transmittal but at an address other than that shown in the box
entitled "Description of Shares Tendered" on the reverse hereof, the appropriate
boxes on the reverse of this Letter of Transmittal must be completed.
 
     8.  QUESTIONS AND REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions
and requests for assistance may be directed to the Information Agent or the
Dealer Managers at their respective addresses or telephone numbers set forth
below. Additional copies of the Offer to Purchase, this Letter of Transmittal
and the Notice of Guaranteed Delivery may be obtained from the Information Agent
or from brokers, dealers, commercial banks or trust companies.
 
     9.  SUBSTITUTE FORM W-9.  Each tendering stockholder 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 stockholder is not subject to backup withholding of federal income tax. If
a tendering stockholder has been notified by the Internal Revenue Service that
such stockholder is subject to backup withholding, such stockholder must cross
out item (2) of the Certification box of the Substitute Form W-9, unless such
stockholder has since been notified by the Internal Revenue Service that such
stockholder is no longer subject to backup withholding. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
31 percent federal income tax withholding on the payment of the purchase price
of all Shares purchased from such stockholder. If the tendering
<PAGE>   8
 
stockholder has not been issued a TIN and has applied for one or intends to
apply for one in the near future, such stockholder should write "Applied For" in
the space provided for the TIN in Part I of the Substitute Form W-9, and sign
and date the Substitute Form W-9. If "Applied For" is written in Part I and the
Depositary is not provided with a TIN within 60 days, the Depositary will
withhold 31 percent on all payments of the purchase price to such stockholder
until a TIN is provided to the Depositary.
 
     IMPORTANT:  THIS LETTER OF TRANSMITTAL (OR FACSIMILE HEREOF), PROPERLY
COMPLETED AND DULY EXECUTED, OR AN AGENT'S MESSAGE IN THE CASE OF A BOOK-ENTRY
DELIVERY (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).
 
                           IMPORTANT TAX INFORMATION
 
     Under the federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary (as payer) with such
stockholder's correct TIN on Substitute Form W-9 below. If such stockholder is
an individual, the TIN is such stockholder's social security number. If the
Depositary is not provided with the correct TIN, the stockholder may be subject
to a $50 penalty imposed by the Internal Revenue Service. In addition, payments
that are made to such stockholder with respect to Shares purchased pursuant to
the Offer may be subject to backup withholding of 31 percent (as described
below).
 
     Certain stockholders (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 an Internal Revenue Service Form W-8,
signed under penalties of perjury, attesting to such individual's exempt status.
A Form W-8 may 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
percent of any payments made to the stockholder. 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 stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of such stockholder's correct TIN by
completing the form below certifying (a) that the TIN provided on Substitute
Form W-9 is correct (or that such stockholder is awaiting a TIN), and (b) that
(i) such stockholder is exempt from backup withholding, (ii) such stockholder
has not been notified by the Internal Revenue Service that such stockholder is
subject to backup withholding as a result of a failure to report all interest or
dividends or (iii) the Internal Revenue Service has notified such stockholder
that such stockholder is no longer subject to backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
     The stockholder 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 stockholder has not been issued a TIN
and has applied for a number or intends to apply for a number in the near
future, the stockholder should write "Applied For" in the space provided for the
TIN in Part I, and sign and date the Substitute Form W-9. If "Applied For" is
written in Part I and the Depositary is not provided with a TIN within 60 days,
the Depositary will withhold 31 percent of all payments of the purchase price to
such stockholder until a TIN is provided to the Depositary.

   IDENTIFICATION NUMBER ("TIN")
                                      (1) The number shown on this form is my correct Taxpayer Identification Number

                                      (2) I am not subject to backup withholding either because (a) I am exempt from
                                    backup withholding, (b) I have not been notified by the Internal Revenue Service
                                    (the "IRS") that I am subject to backup withholding as a result of failure to
                                    report all interest or dividends, or (c) the IRS has notified me that I am no
                                    longer subject to backup withholding.

                                     PAGE 2
 
OBTAINING A NUMBER
If you do not have a taxpayer identification number or you do not know your
number, obtain Form SS-5, Application for a Social Security Number Card (for
individuals), or Form SS-4, Application for Employer Identification Number (for
businesses and all other entities), at an office of the Social Security
Administration or the Internal Revenue Service.
 
  To complete Substitute Form W-9, if you do not have a taxpayer identification
number, write "Applied For" in the space for the taxpayer identification number
in Part 1, sign and date the Form, and give it to the requester. Generally, you
will then have 60 days to obtain a taxpayer identification number and furnish it
to the requester. If the requester does not receive your taxpayer identification
number within 60 days, backup withholding, if applicable, will begin and will
continue until you furnish your taxpayer identification number to the requester.
 
PAYEES EXEMPT FROM BACKUP WITHHOLDING
Payees specifically exempted from backup withholding on ALL payments include the
following:
  - A corporation.
  - A financial institution.
  - An organization exempt from tax under section 501(a), or an individual
    retirement plan, or a custodial account under section 403(b)(7).
  - The United States or any agency or instrumentality thereof.
  - A State, the District of Columbia, a possession of the United States, or any
    subdivision or instrumentality thereof.

  - Payments to partnerships not engaged in a trade or business in the United
    States and which have at least one nonresident partner.
  - Payments of patronage dividends where the amount received is not paid in
    money.
  - Payments made by certain foreign organizations.
  - Payments made to a nominee.
  Payments of interest not generally subject to backup withholding include the
following:
  - Payments of interest on obligations issued by individuals. NOTE: You may be
    subject to backup withholding if (i) this interest is $600 or more, (ii) the
    interest is paid in the course of the payer's trade or business and (iii)
    you have not provided your correct taxpayer identification number to the
    payer.

EXEMPT PAYEES DESCRIBED ABOVE SHOULD FILE A SUBSTITUTE FORM W-9 TO AVOID
POSSIBLE ERRONEOUS BACKUP WITHHOLDING. FILE THIS FORM WITH THE PAYER, FURNISH
YOUR TAXPAYER IDENTIFICATION NUMBER, WRITE "EXEMPT" ON THE FACE OF THE FORM,
SIGN AND DATE THE FORM AND RETURN IT TO THE PAYER.
 
  Certain payments other than interest, dividends, and patronage dividends that
are not subject to information reporting are also not subject to backup
withholding. For details, see the regulations under sections 6041, 6041A(a),
6045, and 6050A.
 
PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividends,
interest, or other payments to give taxpayer identification numbers to payers
who must report the payments to IRS. The IRS uses the numbers for identification
purposes and to help verify the accuracy of your tax return. Payers must be
given the numbers whether or not recipients are required to file tax returns.
Payers must generally withhold 31% of taxable interest, dividends, and certain
other payments to a payee who does not furnish a taxpayer identification number
to a payer. Certain penalties may also apply.
 
PENALTIES
 
(1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER.--If you fail
to furnish your correct taxpayer identification number to a payer, you are
subject to a penalty of $50 for each such failure unless your failure is due to
reasonable cause and not to willful neglect.
 
(2) CIVIL PENALTY FOR FALSE STATEMENTS 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.
 
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.--If you falsify certifications
or affirmations, you are subject to criminal penalties including fines and/or
imprisonment.
 
                  FOR ADDITIONAL INFORMATION CONTACT YOUR TAX
                   CONSULTANT OR THE INTERNAL REVENUE SERVICE

                           UNITED DOMINION INDUSTRIES
                                    LIMITED
 
     UD Delaware Corp., a Delaware corporation ("Purchaser") and an indirect
wholly owned subsidiary of United Dominion Industries Limited, a corporation
organized under the laws of Canada ("Parent"), is offering to purchase all
outstanding shares of common stock, par value $1.00 per share (the "Common
Stock"), of Imo Industries Inc., a Delaware corporation (the "Company"), and
each associated right to purchase shares of the Company's Series B Junior
Participating Preferred Stock (individually, a "Right" and collectively, the
"Rights") issued pursuant to the Rights Agreement dated as of April 30, 1997, as
amended, between the Company and First Chicago Trust Company of New York (such
shares of Common Stock and the Rights are collectively referred to as the
"Shares"), at a price of $6.00 per Share, net to the seller in cash, without
interest thereon, upon the terms and subject to the conditions set forth in the
Offer to Purchase, dated July 2, 1997 (the "Offer to Purchase"), and in the
related Letter of Transmittal (which, as amended from time to time, together
constitute the "Offer"). Following the Offer, Purchaser intends to effect the
Merger described below.
 
       THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW
   YORK CITY TIME, ON WEDNESDAY, JULY 30, 1997, UNLESS THE OFFER IS EXTENDED.
 
     THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST THE
NUMBER OF SHARES THAT SHALL CONSTITUTE MORE THAN EIGHTY PERCENT (80%) OF THE
THEN OUTSTANDING SHARES, (II) THE RECEIPT OF CONSENTS FROM THE HOLDERS OF A
MAJORITY OF THE THEN OUTSTANDING PRINCIPAL AMOUNT OF THE 11 3/4% SENIOR
SUBORDINATED NOTES DUE MAY 1, 2006 OF THE COMPANY (THE "NOTES") TO AMEND CERTAIN
PROVISIONS OF THE INDENTURE GOVERNING THE NOTES SO THAT SUCH PROVISIONS ARE NOT
APPLICABLE TO THE MERGER OR FOLLOWING CONSUMMATION OF THE MERGER OR SUCH OFFER
FOR THE NOTES, AND (III) THE EXPIRATION OR TERMINATION OF ANY APPLICABLE
ANTITRUST WAITING PERIODS.
     The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of June 26, 1997 (the "Merger Agreement"), among Parent, Purchaser and the
Company. The Merger Agreement provides that, among other things, as soon as
practicable after the purchase of Shares pursuant to the Offer and the
satisfaction of the other conditions set forth in the Merger Agreement and in
accordance with relevant provisions of the General Corporation Law of the State
of Delaware ("Delaware Law"), Purchaser will be merged with and into the Company
(the "Merger"). Following consummation of the Merger, the Company will continue
as the surviving corporation as an indirect wholly owned subsidiary of Parent.
At the effective time of the Merger (the "Effective Time"), each Share
(including the associated Right), issued and outstanding immediately prior to
the Effective Time (other than Shares owned by Purchaser, Parent, the Company or
any wholly owned subsidiary of Parent or the Company and any Shares held by
stockholders who shall have properly exercised their rights for appraisal of
such Shares in accordance with Delaware Law) will be cancelled and converted
automatically into the right to receive $6.00 in cash, or any higher price that
may be paid per Share in the Offer, without interest.
     THE BOARD OF DIRECTORS OF THE COMPANY (THE "BOARD") HAS UNANIMOUSLY
DETERMINED THAT EACH OF THE OFFER AND THE MERGER IS FAIR TO AND IN THE BEST
INTERESTS OF THE COMPANY AND ITS STOCKHOLDERS, AND RECOMMENDS THAT STOCKHOLDERS
ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
     Under the Company's Certificate of Incorporation and Delaware Law, the
affirmative vote of the holders of a majority of the outstanding Shares entitled
to vote thereon is required to approve and adopt the Merger Agreement and the
Merger, provided that if Purchaser purchases 90 percent of the Shares then
outstanding, such affirmative vote of the holders of the Shares is not required.
<PAGE>   2
 
     For purposes of the Offer, Purchaser will be deemed to have accepted for
payment (and thereby purchased) Shares validly tendered and not withdrawn as, if
and when Purchaser gives oral or written notice to First Chicago Trust Company
of New York (the "Depositary") of Purchaser's acceptance for payment of such
Shares pursuant to the Offer. Upon the terms and subject to the conditions of
the Offer, payment for Shares accepted for payment pursuant to the Offer will be
made by deposit of the purchase price therefor with the Depositary, which will
act as agent for tendering stockholders for the purpose of receiving payments
from Purchaser and transmitting such payments to tendering stockholders whose
Shares have been accepted for payment. Under no circumstances will interest on
the purchase price for Shares be paid, 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 one of the Book-Entry Transfer Facilities (as defined in
Section 2 of the Offer to Purchase) pursuant to the procedures set forth in
Section 3 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.
     Pursuant to the Merger Agreement, Parent and Purchaser have agreed that,
without the consent of the Company, they will not extend the expiration date of
the Offer (except that Purchaser may extend the expiration date of the Offer (a)
as required to comply with any rule, regulation or interpretation of the
Securities and Exchange Commission or (b) for one or more times each for an
aggregate period of up to 15 days (and not to exceed 60 days from the date of
commencement) for any reason other than those specified in the immediately
preceding clause (a)). Any such extension will be followed as promptly as
practicable by public announcement thereof, such announcement to be made no
later than 9:00 a.m., New York City time, on the next business day after the
previously scheduled expiration date of the Offer. During any such extension,
all Shares previously tendered and not withdrawn will remain subject to the
Offer, subject to the rights of a tendering stockholder to withdraw such
stockholder's Shares.
     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 Wednesday, July 30, 1997 (or the latest time and date at which the
Offer, if extended by Purchaser, shall expire) and, unless theretofore accepted
for payment by Purchaser pursuant to the Offer, may also be withdrawn at any
time after August 30, 1997. For the withdrawal to be effective, a written or
facsimile transmission notice of withdrawal must be timely received by the
Depositary at one of its addresses set forth on the back cover page of the 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 of such Shares, 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 shown on such Share Certificates must be submitted to the Depositary and
the signature(s) on the notice of withdrawal must be guaranteed by an Eligible
Institution (as defined in Section 3 of the Offer to Purchase), unless such
Shares have been tendered for the account of an Eligible Institution. If Shares
have been tendered pursuant to the procedure for book-entry transfer as set

                        UNITED DOMINION TO ACQUIRE TWO
              LEADING INDUSTRIAL MANUFACTURERS FOR $770 MILLION

     CHARLOTTE, NC (June 26, 1997) -- United Dominion Industries Ltd. (NYSE,
TSE: UDI) today announced definitive agreements to acquire all the outstanding
stock of Core Industries, Inc. (NYSE: CRI) and Imo Industries Inc. (NYSE: IMD).
The consideration for the two transactions totals approximately $770 million,
and both transactions have the approval of the respective boards of directors.

     William R. Holland, chairman and chief executive officer of United
Dominion, said these acquisitions complete United Dominion's transformation to
a top-tier company focused solely on the manufacture of proprietary engineered
products for worldwide industrial markets.

     "The two transactions represent a milestone in our efforts to reshape
United Dominion's business mix and enhance margins and profitability," 
Mr. Holland said. "Both acquisitions meet our criteria in all respects. They 
add leading industrial products to our business mix, vastly expand our current
product offerings and provide us with numerous opportunities for expansion
domestically and internationally."

     Recently, United Dominion announced the divestiture of business units in
its Building Products Segment, including Varco-Pruden, Windsor Door, and its 50
percent interest in Centria. These

                                                                        ...more
<PAGE>   2

                                     -2-

divestitures accounted for approximately $455 million of United Dominion's 1996
sales. The new acquisitions are expected to provide additional annual revenues
of approximately $750 million on a pro forma basis.

     "Together with the expenditures for Flair Corporation in 1995, product
line acquisitions and these two transactions, we will have invested roughly the
$1 billion in engineered, manufactured products that we anticipated during our
Vision '99 strategic planning period," Mr. Holland said.

     Core Industries produces specialized industrial products in three
segments; fluid control; test, measurement and control; and farm equipment. 
Its products include Mueller strainers and check valves, FEBCO water backflow
prevention valves, Amprobe electrical test and refrigerant recovery
instruments, GSE/Air Gage fastening tools and gauging systems, and Sunflower
and Feterl/Richardton farm equipment. Headquartered in Bloomfield Hills, Mich.,
the company has 1,800 employees at 18 locations.

     Imo Industries is a global manufacturer of pumps, power transmission
equipment, fluid sensors, motion control products and automotive components for
niche industrial markets. The company derives approximately 45 percent of its
revenues from international operations. Imo's businesses include Boston Gear, a
leading manufacturer of speed reducers and gears for the power transmission
industry; Imo Pump, the largest worldwide manufacturer of rotary screw pumps;
and Gems sensors, a leading manufacturer of liquid sensing, measurement and
control instruments; Morse Controls, a leading producer of remote control
systems for marine and industrial vehicle applications; and Roltra-Morse, a
manufacturer of automobile components, primarily in the Italian market.
Headquartered in Lawrenceville, N.J., the company has 3,700 employees worldwide
at 30 locations in the U.S., Europe and Asia.

                                                                       ...more

                                     -3-

     Through a newly formed subsidiary, United Dominion will begin a tender
offer on or before July 3 for Imo's approximately 17.4 million common shares
(fully diluted) at a price of $6 per share. Simultaneously, United Dominion
will tender Imo's $155 million 11 3/4 percent subordinated debentures due 2006
at 120 percent of outstanding principal. Including the assumption of Imo's
other debt and closing expenses, total value of the transaction will be
approximately $440 million.

     Similar arrangements will be made through another newly formed United
Dominion subsidiary to purchase Core Industries' 11.1 million common shares
(fully diluted) at a price of $25 per share. This transaction will total
approximately $330 million including assumed debt and closing expenses.

     United Dominion also said that Core has agreed to pay United Dominion a
$10 million termination fee and that Imo has agreed to pay United Dominion an
$8 million termination fee, both subject to certain circumstances.

     The Core offer is subject to the tender of a majority of the outstanding
shares and certain other conditions including the expiration or termination of
the waiting periods under the Hart-Scott-Rodino Antitrust Improvement Act of
1976. In the case of Imo, the offer is subject to the tender of a majority
of the principal amount of $155 million of subordinated debentures and more
than 80 percent of the outstanding shares and certain other conditions
including the expiration or termination of the waiting periods under the
Hart-Scott-Rodino Antitrust Improvement Act of 1976. The tender offers will be
followed by a merger in which each remaining share will be converted into the
right to receive the cash price per share paid in the offer. The stock tender
offers will be made only through offering documents, which will be filed
promptly with the Securities and Exchange Commission and mailed to Core and Imo
stockholders respectively.

                                                                        ...more

                                     -4-

     After completing these transactions, United Dominion, a diversified
manufacturer of industrial and commercial products will have revenues of
approximately $2.4 billion and employ approximately 14,100 people at 92
locations in 18 countries.

NEWS RELEASE


FOR IMMEDIATE RELEASE

         IMO INDUSTRIES ANNOUNCES SALE TO UNITED DOMINION INDUSTRIES


LAWRENCEVILLE, NJ (June 26, 1997) -- Imo Industries Inc. (NYSE: IMD) announced
today that Imo and United Dominion Industries Limited (NYSE, TSE, [MTLE]: UDI)
have executed a definitive merger agreement providing for the acquisition of
Imo by United Dominion. Under the terms of the merger agreement, United
Dominion will commence a cash tender offer for all outstanding shares of Imo
common stock at a price of $6 per share, net in cash. The purchase price
represents a premium of approximately 89% over the average trading price of the
last 90 days.

Simultaneously with the tender offer for the shares of Imo common stock, United
Dominion also will commence an offer to purchase for cash at 120% of the
principal amount thereof all of Imo's 11 3/4% Senior Subordinated Notes due
2006 (of which $155 million are outstanding) and solicit consents from the
holders of the notes to obtain certain amendments to the indenture in
connection with the merger. The tender offer for the shares of Imo common stock
is conditioned on the receipt of 80% of the shares and the tender offer for the
notes is conditioned on receipt of a majority of the principal amount of the
notes. Each offer is conditioned on the successful completion of the other and
certain other customary conditions. Any shares not purchased in the tender
offer will be acquired in a subsequent merger at the same $6 per share net cash
price, to be effected as soon as practicable after the completion of the tender
offer and the offer to purchase. Any notes not purchased in the offer to
purchase will remain outstanding.

The Board of Directors of Imo has approved the merger agreement, the tender
offer for the shares, the offer to purchase for the notes and the merger,
determined that the tender offer and the merger are fair to, and in the best
interests of Imo's stockholders and recommended that Imo's stockholders accept
the tender offer and approve and adopt the merger agreement. The Board of
Directors was advised by Credit Suisse First Boston Corporation, financial
advisor to the Board of Directors, that the consideration to be received by
holders of Imo common stock was fair to such holders from a financial point of
view.

order to enhance shareholder value. We believe the acquisition of Imo by United
Dominion at the significant premium to market will provide our shareholders with
excellent value, and the strong balance sheet and operating history of United
Dominion will allow us to improve our operations and continue to deliver
superior products to our customers."

United Dominion is expected to commence its tender offer for all the common
stock of Imo and its offer to purchase all of the notes on or before July 3,
1997.

Imo Industries, with 1996 sales of $469 million, is a diversified manufacturer

Dear Glenn:
 
     I am glad that we finally made it on Friday to meet with you and the rest
of the UDI team to review the proposed acquisitions of "Apple" and "Orange".
Following our discussions on Friday and this morning, we are pleased to submit
Royal Bank's firm offer to arrange a US$650 million five year revolving credit
facility and a US$150 million 364 day revolving credit facility. It is our
understanding that these facilities will be used to demonstrate UDI's ability to
finance a controlling interest in the shares of both "Apple" and "Orange".
 
     The Royal Bank of Canada has fully underwritten both facilities, subject
only to satisfactory documentation which we expect would essentially mirror the
terms and conditions attached as well as those contained in your June 20, 1996
revolving credit facility (as amended). Pricing on the various facilities has
been significantly reduced however in order to bring the transaction in line
with current market conditions.
 
     As was briefly discussed with you, we believe that the new facilities can
be syndicated to your existing bank group plus a select group of new lenders if
necessary to hedge the possibility that either some lenders are unable to commit
either at a higher level or due to potential conflicts. In any event, we feel
comfortable that the facility will be comfortably subscribed.
 
     The fees that we propose to charge UDI in connection with the transaction
are contained in the attached fee letter. If you are in agreement with these
terms and conditions, please sign and return one copy of the summary term sheet
and fee letter. The second copies are for your records.
 
     Thank you for your continued confidence in RBC and I very much look forward
to working with you and Tom on this and other deals over the next few years.
Please let me know should you have any questions or concerns.
 
                                          Sincerely,
 
                                                 /s/ JOHN M. CRAWFORD

         AGREEMENT AND PLAN OF MERGER, dated as of June 26, 1997 (this
"Agreement"), among UNITED DOMINION INDUSTRIES LIMITED, a corporation organized
under the laws of Canada ("Parent"), UD DELAWARE CORP., a Delaware corporation
and an indirect wholly owned subsidiary of Parent ("Purchaser"), and IMO
INDUSTRIES INC., a Delaware corporation (the "Company").

                                   WITNESSETH:

         WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
have each determined that it is in the best interests of their respective
stockholders for Parent to acquire the Company upon the terms and subject to the
conditions set forth herein; and

         WHEREAS, in furtherance of such acquisition, it is proposed that
Purchaser shall make a cash tender offer (the "Offer") to acquire all the issued
and outstanding shares of common stock, par value U.S. $1.00 per share, of the
Company (the "Shares"), together with the associated Rights (as hereinafter
defined), for U.S. $6.00 per Share (such amount, or any greater amount per Share
paid pursuant to the Offer, being hereinafter referred to as the "Per Share
Amount") net to the seller in cash, subject to withholding of taxes, if
applicable, upon the terms and subject to the conditions of this Agreement and
the Offer; and

         WHEREAS, also in furtherance of such acquisition, it is proposed that,
simultaneously with the Offer, Parent shall make an offer to purchase for cash
(the "Note Offer to Purchase") all of the Company's 11 3/4% Senior Subordinated
Notes due 2006 (the "Notes") and solicit consents ("Consents") from the holders
of the Notes to amend the Indenture (as defined herein) as herein provided (the
"Consent Solicitation" and collectively with the Note Offer to Purchase, the
"Note Tender Offer") at a price of 120% of the principal amount of the Notes,
upon the terms and subject to the conditions of this Agreement and the Note
Tender Offer; and

         WHEREAS, the Board of Directors of the Company (the "Board"), including
all the disinterested directors on the Board, has unanimously approved the
making of the Offer and the Note Tender Offer and resolved and agreed to
recommend that holders of Shares tender their Shares pursuant to the Offer; and

         WHEREAS, the Boards of Directors of Parent, Purchaser and the Company
have each approved the merger (the "Merger") of Purchaser with and into the
Company in accordance with the General Corporation Law of the State of Delaware
("Delaware Law") following the consummation of the Offer and the Note Tender
Offer and upon the terms and subject to the conditions set forth herein;

         NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Parent, Purchaser and the Company hereby agree as follows:



<PAGE>   7

                                   ARTICLE I.

                                    THE OFFER

                  SECTION 1.01 The Offer. (a) Provided that this Agreement shall
not have been terminated in accordance with Section 8.01 and none of the events
or circumstances set forth in Annex A hereto shall have occurred or be existing,
Purchaser agrees to, and Parent agrees to cause Purchaser to, commence the Offer
as promptly as reasonably practicable after the date hereof, but in no event
later than five business days after the first public announcement of the
execution hereof. Parent and Purchaser agree that the obligation of Purchaser to
accept for payment and pay for Shares tendered pursuant to the Offer shall be
subject to the condition (the "Minimum Condition") that the number of Shares
validly tendered and not withdrawn prior to the expiration of the Offer,
combined with the Shares already owned by Parent, Purchaser or any of their
affiliates, constitute more than 80% of the outstanding Shares at the expiration
of the Offer and also shall be subject to the satisfaction of the other
conditions set forth in Annex A. Purchaser expressly reserves the right to waive
any such condition, to increase the price per Share payable in the Offer, and to
make any other changes in the terms and conditions of the Offer; provided,
however, that Parent and Purchaser agree that no change may be made without the
consent of the Company which decreases the price per Share payable in the Offer,
which changes the form of consideration to be paid in the Offer, which reduces
the maximum number of Shares to be purchased in the Offer, which extends the
expiration date of the Offer (except that Purchaser may extend the expiration
date of the Offer (a) as required to comply with any rule, regulation or
interpretation of the Securities and Exchange Commission (the "SEC") or (b) for
one or more times each for an aggregate period of up to 15 days (and not to
exceed 60 days from the date of commencement) for any reason other than those
specified in the immediately preceding clause (a)) or which imposes conditions
to the Offer in addition to those set forth in Annex A hereto. The Per Share
Amount shall, subject to applicable withholding of taxes, be net to the seller
in cash, upon the terms and subject to the conditions of the Offer. Subject to
the terms and conditions of the Offer (including, without limitation, the
Minimum Condition), Purchaser agrees to, and Parent agrees to cause Purchaser
to, pay, as promptly as practicable after expiration of the Offer, for all
Shares validly tendered and not withdrawn.

         (b) As soon as reasonably practicable on the date of commencement of
the Offer, Parent and Purchaser agree that Purchaser will file with the SEC a
Tender Offer Statement on Schedule 14D-1 (together with all amendments and
supplements thereto, the "Schedule 14D-1") with respect to the Offer and the
other Transactions (as hereinafter defined), which shall have been provided to
the Company and to which the Company shall not have reasonably objected. Parent
and Purchaser agree that the Schedule 14D-1 will contain or will incorporate by
reference an offer to purchase (the "Offer to Purchase") and forms of the
related letter of transmittal and any related summary advertisement (the
Schedule 14D-1, the Offer to Purchase 


                                      2

and such other documents, together with all supplements and amendments thereto,
being referred to herein collectively as the "Offer Documents"). Parent,
Purchaser and the Company agree to correct promptly any information provided by
any of them for use in the Offer Documents which shall have become false or
misleading, and Parent and Purchaser further agree to take all steps necessary
to cause the Schedule 14D-1 as so corrected to be filed with the SEC and the
other Offer Documents as so corrected to be disseminated to holders of Shares,
in each case as and to the extent required by applicable federal securities
laws.

         SECTION 1.02  Note Tender Offer.

         (a) Provided that this Agreement shall not have been terminated in
accordance with Section 8.01 and none of the events or circumstances set forth
in Annex B hereto shall have occurred or be existing, Parent agrees that it or
its designee will commence the Note Offer to Purchase as promptly as reasonably
practicable after the date hereof, but in no event later than five business days
after the first public announcement of the execution hereof. In connection with
the Note Offer to Purchase, Parent intends to solicit Consents to amend Sections
4.02 (other than the first and last sentences thereof), 4.03(a) (in order to
permit loans to be made to the Company by its affiliates), 4.04 (in order to
eliminate the restrictions on indebtedness of the Company's foreign
subsidiaries), 4.05, 4.06, 4.07, 4.08, 4.09, 4.11, 4.12, 4.16 and 5.01(a)(iii)
of the Indenture and any other sections thereof agreed to by the Company, so
that such Sections are not applicable to the Merger or following the
consummation of the Note Tender Offer or the Merger. Parent agrees that its
obligation to accept for payment and pay for the Notes and related Consents
tendered pursuant to the Note Tender Offer shall be subject to the condition
that Parent receive Consents from a majority of the outstanding principal amount
of the Notes (the "Requisite Consent Condition") and also shall be subject to
the satisfaction of the other conditions set forth in Annex B hereto. Parent
expressly reserves the right to waive any such condition, to increase the price
payable for each Note and related Consent tendered in the Note Tender Offer, and
to make any other changes in the terms and conditions of the Note Tender Offer;
provided, however, that Parent agrees that no change may be made without the
consent of the Company which decreases the price payable for each Note and
related Consent tendered in the Note Tender Offer, which changes the form of
consideration to be paid in the Note Tender Offer, which reduces the maximum
number of Notes to be purchased in the Note Tender Offer or which imposes
conditions to the Note Tender Offer in addition to those set forth in Annex B
hereto. Subject to the terms and conditions of the Note Tender Offer (including,
without limitation, the Requisite Consent Condition), Parent agrees to pay, as
promptly as practicable after expiration of the Note Tender Offer, for all Notes
and related Consents validly tendered and not withdrawn.

         (b) Parent agrees to disseminate to the record holders of the Notes,
and to the extent disclosed to Parent by the Company, the beneficial owners of
the Notes (collectively, the "Noteholders"), the Note Tender Offer pursuant to
the terms of an offer to purchase and consent solicitation statement, together
with related letters of transmittal and similar ancillary agreements (such
documents, together with all supplements and amendments thereto, being referred
to herein collectively as the "Note Tender Offer Documents"), which shall have
been 




                                      3

<PAGE>   9


provided to the Company and to which the Company shall not have reasonably
objected. Parent, Purchaser and the Company agree to correct promptly any
information provided by any of them for use in the Note Tender Offer Documents
which shall have become false or misleading, and Parent further agrees to take
all steps necessary to cause the Note Tender Offer Documents as so corrected to
be disseminated to holders of Notes, in each case as and to the extent required
by applicable federal securities laws.

         (c) Assuming the Requisite Consent Condition is satisfied and all other
conditions to the Note Tender Offer set forth on Annex B have been satisfied or
waived by Parent, the Company agrees to execute, and will use all reasonable
efforts to cause the trustee under the Indenture to execute, a supplemental
indenture (the "Supplemental Indenture") in order to give effect to the
amendments of the Indenture contemplated in the Note Tender Offer Documents
immediately following the expiration date of the Note Tender Offer; provided,
however, that the proposed amendments set forth in the Supplemental Indenture
(the "Proposed Amendments") will not become operative until the date Parent
accepts all Notes (and related Consents) validly tendered for purchase and
payment pursuant to the Note Tender Offer. In such event, the parties hereto
agree  that the Proposed Amendments will be deemed effective as of immediately
prior to such acceptance for payment, and Parent will thereafter be obligated to
make all payments for the Notes (and related Consents) so tendered.

         (d) The Company agrees to promptly furnish Parent with mailing labels
containing the names and addresses of all record holders of Notes and with
security position listings of the Notes held in depositories, each as of a
recent date, together with all other available listings and computer files
containing names, addresses and security position listings of Noteholders. The
Company agrees to furnish Parent with such additional information, including,
without limitation, updated listings and computer files of Noteholders, mailing
labels and security position listings, and such other assistance as Parent or
its agents may reasonably request. Subject to the requirements of applicable
law, and except for such steps as are necessary to disseminate the Note Tender
Offer Documents and any other documents necessary to consummate the transactions
contemplated thereby, Parent shall hold in confidence the information contained
in such labels, listings and files, shall use such information only in
connection with the Note Tender Offer and, if this Agreement shall be terminated
in accordance with Section 8.01, shall deliver to the Company all copies of such
information then in its possession.

         SECTION 1.03 Company Action. (a) The Company hereby approves of and
consents to the Offer and the Note Tender Offer and represents that (i) the
Board, at a meeting duly called and held on June 25, 1997, has unanimously (A)
determined that this Agreement and the transactions contemplated hereby,
including each of the Offer and the Merger, are fair to and in the best
interests of the stockholders of the Company, (B) approved and adopted this
Agreement and the transactions contemplated hereby, including, without
limitation, the Merger, and such approval constitutes approval of the foregoing
for purposes of Section 203 of Delaware Law, (C) taken all action to avoid the
occurrence of a "Distribution Date" or a "Triggering Event" (each as defined in
the Rights Agreement referred to in Section 2.06) with respect to the Rights and
(D) recommended that the stockholders of the Company accept the Offer and
approve and adopt this Agreement and the transactions contemplated hereby,
including, without limitation, the Merger, and (ii) Credit Suisse First Boston
Corporation ("Credit Suisse First Boston") has delivered to the Board a written
opinion to the effect that, as of the date of such opinion, the consideration to
be received by the holders of Shares (other than Parent, Purchaser and their
affiliates) pursuant to each of the Offer and the Merger is fair to such holders
of Shares from a financial point of view. Subject only to the fiduciary duties
of the Board under applicable law as advised by the Company's counsel, the
Company hereby consents to the inclusion in the Offer Documents of the
recommendation of the Board described in the immediately preceding sentence. The
Company represents to Purchaser that the Company has been advised by each of its
directors and executive officers that they intend either to tender or cause to
be tendered all Shares beneficially owned by them to Purchaser pursuant to the
Offer or to vote such Shares in favor of the approval and adoption by the
stockholders of the Company of this Agreement and the transactions contemplated
hereby.

         (b) As soon as reasonably practicable on the date of commencement of
the Offer, the Company agrees that it will file with the SEC a
Solicitation/Recommendation Statement on Schedule 14D-9 (together with all
amendments and supplements thereto, the "Schedule 14D-9") containing, subject
only to the fiduciary duties of the Board under applicable law as advised by the
Company's counsel, the recommendation of the Board described in Section 1.03(a)
and shall disseminate the Schedule 14D-9 to the extent required by Rule 14d-9
promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and any other applicable federal securities laws. The Company, Parent and
Purchaser agree to correct promptly any information provided by any of them for
use in the Schedule 14D-9 which shall have become false or misleading, and the
Company further agrees to take all steps necessary to cause the Schedule 14D-9
as so corrected to be filed with the SEC and disseminated to holders of Shares,
in each case as and to the extent required by applicable federal securities
laws.

         (c) The Company agrees to promptly furnish Purchaser with mailing
labels containing the names and addresses of all record holders of Shares and
with security position listings of Shares held in stock depositories, each as of
a recent date, together with all other available listings and computer files
containing names, addresses and security position listings of record holders and
beneficial owners of Shares. The Company agrees to furnish Purchaser with such
additional information, including, without limitation, updated listings and
computer 



                                      5

<PAGE>   11



files of stockholders, mailing labels and security position listings, and such
other assistance as Parent, Purchaser or their agents may reasonably request.
Subject to the requirements of applicable law, and except for such steps as are
necessary to disseminate the Offer Documents and any other documents necessary
to consummate the Offer or the Merger, Parent and Purchaser shall hold in
confidence the information contained in such labels, listings and files, shall
use such information only in connection with the Offer and the Merger and, if
this Agreement shall be terminated in accordance with Section 8.01, shall
deliver to the Company all copies of such information then in their possession.

         SECTION 1.04 Parent Action. Parent agrees that (a) Parent will cause
the Company to be provided with sufficient funds immediately prior to the
Purchaser's Election Date, to refinance the Company's obligations under the
Credit Agreement, dated as of April 29, 1996 (the "Credit Agreement"), among the
Company, Varo Inc., Warren Pumps Inc., the lenders from time to time party
thereto, the issuing banks from time to time party thereto and Citicorp USA,
Inc., as Agent, as amended, (b) from and after the Purchaser's Election Date,
Parent will cause the Company to be provided with sufficient funds, on terms
that comply with the Indenture dated as of April 15, 1996 (the "Indenture"),
between the Company and IBJ Schroder Bank & Trust Company, as Trustee, with
respect to the Notes to satisfy the Company's obligations under Section 4.10 of
the Indenture and (c) that such funds will be provided to the Company on terms
no less favorable to the Company than those contained in the Credit Agreement.


                                   ARTICLE II.

                                   THE MERGER

         SECTION 2.01 The Merger. Upon the terms and subject to the conditions
set forth in Article VII, and in accordance with Delaware Law, at the Effective

be governed by the laws of the State of Delaware.

         SECTION 2.02 Effective Time; Closing. As promptly as practicable after
the satisfaction or, if permissible, waiver of the conditions set forth in

filing a certificate of merger (the "Certificate of Merger") with the Secretary
of State of the State of Delaware, in such form as is required by, and executed
in accordance with the relevant provisions of, Delaware Law. The Merger shall
become effective upon such filing or at such time thereafter as is provided in
the Certificate of Merger as the Company and Purchaser shall agree (the
"Effective Time"). Prior to such filing, a closing shall be held at the offices
of Robinson, Bradshaw & Hinson, P.A., 1900 Independence Center, Charlotte, 
North Carolina 28246, or such other place as the 




                                      6

parties shall agree, for the purpose of confirming the satisfaction or waiver,
as the case may be, of the conditions set forth in Article VII.

         SECTION 2.03 Effect of the Merger. At the Effective Time, the effect of
the Merger shall be as provided in the applicable provisions of Delaware Law.

restrictions, disabilities and duties of the Surviving Corporation.

         SECTION 2.04 Certificate of Incorporation; Bylaws. (a) The Certificate
of Incorporation of the Company, as in effect immediately prior to the Effective
Time, shall be the Certificate of Incorporation of the Surviving Corporation
until thereafter amended as provided by applicable law and such Certificate of
Incorporation.

         (b) The Bylaws of the Company, as in effect immediately prior to the

Surviving Corporation and such Bylaws.

         SECTION 2.05 Directors and Officers. The directors of Purchaser
immediately prior to the Effective Time shall be the initial directors of the
Surviving Corporation, each to hold office in accordance with the Certificate of
Incorporation and Bylaws of the Surviving Corporation, and the officers of the
Company immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, in each case until their respective successors are
duly elected or appointed and qualified.

         SECTION 2.06 Conversion of Securities. At the Effective Time, by virtue
of the Merger and without any action on the part of Purchaser, the Company or
the holders of any of the Shares:

                  (a) Each Share, together with the associated right to purchase
         shares of Series B Junior Participating Preferred Stock, par value
         $1.00 (individually, the "Right" and collectively, the "Rights"),
         issued pursuant to the Rights Agreement dated as of April 30, 1997,
         between the Company and First Chicago Trust Company of New York, as
         Rights Agent (the "Rights Agreement"), issued and outstanding
         immediately prior to the Effective Time (other than any Shares to be
         canceled pursuant to Section 2.06(b) and Dissenting Shares (as defined
         in Section 2.09)) shall be canceled and shall be converted
         automatically into the right to receive an amount equal to the Per
         Share Amount in cash (the "Merger Consideration"), payable, without
         interest, to the holder of such Share, upon surrender, in the manner
         provided in Section 2.08, of the certificate that formerly evidenced
         such Share;



                                      7

<PAGE>   13


                  (b) Each Share, together with the associated Right, owned by
         Purchaser, Parent, the Company or any direct or indirect wholly owned
         subsidiary of Parent or of the Company immediately prior to the
         Effective Time shall be canceled and retired without any conversion
         thereof and no payment or distribution shall be made with respect
         thereto; and

                  (c) Each share of common stock of Purchaser issued and
         outstanding immediately prior to the Effective Time shall be converted
         into and exchanged for one validly issued, fully paid and nonassessable
         share of common stock, par value U.S. $1.00 per share, of the Surviving
         Corporation.

         SECTION 2.07 Employee and Director Stock Options; Deferred Director
Fees.

                  (a) In accordance with the terms of the Company's Amended and
         Restated Equity Incentive Plan for Key Employees, the Company's Amended
         and Restated 1988 Equity Incentive Plan for Outside Directors or the
         Company's 1995 Equity Incentive Plan for Outside Directors
         (collectively, the "Stock Option Plans"), each outstanding option to
         purchase Shares granted under the Stock Option Plans shall, immediately
         prior to the Effective Time, become exercisable regardless of the
         vesting schedule contained in any stock option agreement or in any of
         the Stock Option Plans and shall be canceled at the Effective Time. In
         the event that any unexercised option is canceled by the Company, each
         holder of a canceled option shall be entitled to receive, at the
         Effective Time or as soon as practicable thereafter, from the Company,
         in consideration for the cancellation of such option, an amount
         (subject to any applicable withholding tax) in cash equal to the
         product of (i) the number of Shares previously subject to such option
         and (ii) the excess, if any, of the Merger Consideration over the
         exercise price per Share previously subject to such option.

                  (b) At the Effective Time, the Company shall pay to each
         individual who served as a Director of the Company prior to the
         Effective Time any and all deferred director fees owed to such
         individual.

         SECTION 2.08 Surrender of Shares: Stock Transfer Books. (a) Prior to
the Effective Time, Purchaser shall designate a bank or trust company to act as
agent (the "Paying Agent") for the holders of Shares in connection with the
Merger to receive the funds to which holders of Shares shall become entitled
pursuant to Section 2.06(a), and Parent shall cause the Purchaser to deposit
with such Paying Agent an amount sufficient to pay the aggregate Merger
Consideration. Such funds shall be invested by the Paying Agent as directed by
the Surviving Corporation, provided that such investments shall be in
obligations of or guaranteed by the United States of America or of any agency
thereof and backed by the full faith and credit of the United States of America
or in commercial paper obligations rated A-1 or P-1 or better by Moody's
Investors Service, Inc. or Standard & Poor's Ratings Group, respectively.


                                      8

<PAGE>   14


         (b) Promptly after the Effective Time, the Surviving Corporation shall
cause to be mailed to each person who was, at the Effective Time, a holder of
record of Shares entitled to receive the Merger Consideration pursuant to
Section 2.06(a) a form of letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the certificates
evidencing such Shares (the "Certificates") shall pass, only upon proper
delivery of the Certificates to the Paying Agent) and instructions for use in
effecting the surrender of the Certificates pursuant to such letter of
transmittal (or, if such Shares are uncertificated, such other form of evidence
of record ownership as is required by the Paying Agent). Upon surrender to the
Paying Agent of a Certificate (or, with respect to uncertificated Shares, such
other evidence of record ownership as is required by the Paying Agent), together
with such letter of transmittal, duly completed and validly executed in
accordance with the instructions thereto, and such other documents as may be
required pursuant to such instructions, the holder of such Certificate (or
uncertificated Share,  as the case may be) shall be entitled to receive in
exchange therefor the Merger Consideration for each Share formerly evidenced by
such Certificate (or uncertificated Share, as the case may be), and such
Certificate (or uncertificated Share, as the case may be) shall then be
canceled. No interest shall accrue or be paid on the Merger Consideration
payable upon the surrender of any Certificate (or uncertificated Share, as the
case may be) for the benefit of the holder of such Certificate (or
uncertificated Share, as the case may be). If payment of the Merger
Consideration is to be made to a person other than the person in whose name the
surrendered Certificate (or uncertificated Share, as the case may be) is
registered on the stock transfer books of the Company, it shall be a condition
of payment to the holder of a Certificate that it be endorsed properly or, with
respect to Certificates and uncertificated Shares, otherwise be in proper form
for transfer and that, with respect to Certificates and uncertificated Shares,
the person requesting such payment shall have paid all transfer and other taxes
required by reason of the payment of the Merger Consideration to a person other
than the registered holder thereof or shall have established to the satisfaction
of the Surviving Corporation that such taxes either have been paid or are not
applicable.

         (c) At any time following the sixth month after the Effective Time, the
Surviving Corporation shall be entitled to require the Paying Agent to deliver
to it any funds which had been made available to the Paying Agent and not
disbursed to holders of Shares (including, without limitation, all interest and
other income received by the Paying Agent in respect of all funds made available
to it) and, thereafter, such holders shall be entitled to look to the Surviving
Corporation (subject to abandoned property, escheat and other similar laws) only
as general creditors thereof with respect to any Merger Consideration that may
be payable upon due surrender of the Certificates held by them (or, if such
Shares are uncertificated, such other form of evidence of record ownership as is
required by the Paying Agent). Notwithstanding the foregoing, neither the
Surviving Corporation nor the Paying Agent shall be liable to any holder of a
Share for any Merger Consideration delivered in respect of such Share to a
public official pursuant to any abandoned property, escheat or other similar
law.


                                      9
<PAGE>   15


         (d) At the close of business on the day of the Effective Time, the
stock transfer books of the Company shall be closed and, thereafter, there shall
be no further registration of transfers of Shares on the records of the Company.
From and after the Effective Time, the holders of Shares outstanding immediately
prior to the Effective Time shall cease to have any rights with respect to such
Shares except as otherwise provided herein or by applicable law.

         SECTION 2.09 Dissenting Shares. Notwithstanding any other provision of
this Agreement to the contrary, Shares that are outstanding immediately prior to
the Effective Time and which are held by stockholders who shall have not voted
in favor of the Merger or consented thereto in writing and who properly shall
have demanded appraisal for such shares in accordance with Delaware Law
(collectively, the "Dissenting Shares") shall not be converted into or represent
the right to receive the Merger Consideration. Such stockholders instead shall
be entitled to receive payment of the appraised value of such Shares held by
them in accordance with the provisions of Delaware Law, except that all
Dissenting Shares held by stockholders who shall have failed to perfect or who
effectively shall have withdrawn or otherwise lost their rights to appraisal of
such Shares under Delaware Law shall thereupon be deemed to have been converted
into and to have become exchangeable, as of the Effective Time, for the right to
receive, without any interest thereon, the Merger Consideration upon surrender
in the manner provided in Section 2.08, of the Certificate or Certificates (or,
if such Shares are uncertificated, such other form of evidence of record
ownership as is required by the Paying Agent) that, immediately prior to the
Effective Time, evidenced such Shares.


                                  ARTICLE III.

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company hereby represents and warrants to Parent and Purchaser
that:

         SECTION 3.01 Organization and Qualification; Subsidiaries. Each of the
Company and each subsidiary of the Company (a "Subsidiary") is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its incorporation and has the requisite power and authority and
all necessary governmental approvals to own, lease and operate its properties
and to carry on its business as it is now being conducted, except where the
failure to be so organized, existing or in good standing or to have such power,
authority and governmental approvals would not, individually or in the
aggregate, have a Material Adverse Effect (as defined below). The Company and
each Subsidiary is duly qualified or licensed as a foreign corporation to do
business, and is in good standing, in each jurisdiction where the character of
the properties owned, leased or operated by it or the nature of its business
makes such qualification or licensing necessary, except for such failures to be
so qualified or licensed and in good standing that would not, individually or in
the aggregate, have a Material Adverse Effect. When used in connection with the
Company or any Subsidiary, the term "Material Adverse Effect" means any effect
that is or is reasonably likely 



                                      10


<PAGE>   16


to be materially adverse to the business, operations, financial condition,
assets or liabilities (including, without limitation, contingent liabilities) of
the Company and the Subsidiaries taken as a whole. A true and complete list of
all the Subsidiaries, together with the jurisdiction of incorporation of each
Subsidiary and the percentage of the outstanding capital stock of each
Subsidiary owned by the Company and each other Subsidiary, is set forth in
Section 3.01 of the Disclosure Schedule, which has been delivered prior to the
date of this Agreement by the Company to Parent (the "Disclosure Schedule").
Except as disclosed in such Section 3.01, the Company does not directly or
indirectly own any equity or similar interest in, or any interest convertible
into or exchangeable or exercisable for any equity or similar interest in, any
corporation, partnership, limited liability company, joint venture or other
business association or entity. The term "Material Subsidiaries" means the
Subsidiaries identified as Material Subsidiaries in Section 3.01 of the
Disclosure Schedule. The Subsidiaries that are not Material Subsidiaries are
not, individually and in the aggregate, material to the business, operations or
financial condition of the Company and all of the Subsidiaries taken as a whole
and do not, individually and in the aggregate, have any material assets or
liabilities (including contingent liabilities) when considered in relation to
the Company and all of the Subsidiaries taken as a whole.

         SECTION 3.02 Certificate of Incorporation and Bylaws. The Company has
heretofore furnished or made available to Parent a complete and correct copy of
the Certificate of Incorporation and the Bylaws or equivalent organizational
documents, each as amended to date (the "Constituent Documents"), of the Company
and each Material Subsidiary. The Constituent Documents of the Company and its
Material Subsidiaries are in full force and effect. Neither the Company nor any
Material Subsidiary is in violation of any provision of its Constituent
Documents.

         SECTION 3.03 Capitalization. The authorized capital stock of the
Company consists of 5,000,000 shares of preferred stock (none of which is issued
and outstanding) and 25,000,000 Shares. As of June 24, 1997, (i) 17,126,609
Shares are issued and outstanding, all of which are validly issued, fully paid
and nonassessable, (ii) no Shares are held by the Subsidiaries, and (iii)
2,882,657 Shares are reserved for issuance pursuant to grants or awards under
the Stock Option Plans. Except as set forth in this Section 3.03 or Section 3.03
of the Disclosure Schedule, there are no options, warrants or other rights,
agreements, arrangements or commitments of any character  obligating the Company
or any Material Subsidiary to issue or sell any shares of capital stock of, or
other equity interests in, the Company or any Material Subsidiary. Section 3.03
of the Disclosure Schedule sets forth a list, as of the date hereof, of the
names of each person holding options under the Stock Option Plans, and the
number of shares purchasable under, the exercise price of such options and date
such options were granted. All Shares subject to issuance as aforesaid, upon
issuance on the terms and conditions specified in the instruments pursuant to
which they are issuable, will be duly authorized, validly issued, fully paid and
nonassessable. Except as set forth in Section 3.03 of the Disclosure Schedule,
there are no outstanding contractual obligations of the Company or any
Subsidiary to repurchase, redeem or otherwise acquire any Shares or any capital
stock of 



                                      11
<PAGE>   17


any Subsidiary or to provide funds to, or make any investment (in the form of a
loan, capital contribution or otherwise) in, any Subsidiary or any other person.
Each outstanding share of capital stock of each Material Subsidiary is duly
authorized, validly issued, fully paid and nonassessable, and, except as set
forth in Section 3.03 of the Disclosure Schedule, each such share owned by the
Company or another Subsidiary is owned free and clear of all security interests,
liens, claims, pledges, options, rights of first refusal, agreements,
limitations on the Company's or such other Subsidiary's voting rights, charges
and other encumbrances of any nature whatsoever.

         SECTION 3.04 Authority Relative to this Agreement. The Company has all
necessary corporate power and authority to execute and deliver this Agreement,
to perform its obligations hereunder and to consummate the transactions
contemplated hereby, including, without limitation, the Merger, the Offer and
the Note Tender Offer (the "Transactions"). The execution and delivery of this
Agreement by the Company and the consummation by the Company of the Transactions
have been duly and validly authorized by all necessary corporate action and no
other corporate proceedings on the part of the Company are necessary to
authorize this Agreement or to consummate the Transactions (other than, with
respect to the Merger, the approval and adoption of this Agreement by the
affirmative vote of the stockholders of the Company to the extent required by
Delaware Law, the filing of the Certificate of Merger and, with respect to the
execution of the Supplemental Indenture, the satisfaction of the Requisite
Consent Condition). This Agreement has been duly and validly executed and
delivered by the Company and, assuming the due authorization, execution and
delivery by Parent and Purchaser, constitutes a legal, valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms.

         SECTION 3.05 No Conflict; Required Filings and Consents. (a) Except as
set forth in Section 3.05(a) of the Disclosure Schedule, the execution and
delivery of this Agreement by the Company do not, and the performance of this
Agreement by the Company will not, (i) conflict with or violate the Constituent
Documents of the Company or any Material Subsidiary, (ii) assuming that required
filings under the HSR Act (as hereinafter defined) are made by the appropriate
parties, conflict with or violate any law, rule, regulation, order, judgment or
decree applicable to the Company or any Subsidiary or by which any property or
asset of the Company or any Subsidiary is bound or affected or (iii) result in
any breach of or constitute a default (or an event which with notice or lapse of
time or both would become a default) under, or give to others any right of
termination, amendment, acceleration or cancellation of, or result in the
creation of a lien or other encumbrance of any nature on any property or asset
of the Company or any Material Subsidiary pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company or any Material Subsidiary is a
party or by which the Company or any Material Subsidiary or any property or
asset of the Company or any Material Subsidiary is bound or affected, except, in
cases of (ii) and (iii), for any such conflicts, violations, breaches, defaults
or other occurrences which would not, individually or in the aggregate, have a
Material Adverse Effect.

         (b) Except as set forth in Section 3.05(b) of the Disclosure Schedule,
the execution and delivery of this Agreement by the Company do not, and the
performance of this Agreement by the Company will not, require any consent,
approval, authorization or permit of, or filing with, or notification to, any
governmental or regulatory authority, domestic or foreign, except (i) for
applicable requirements, if any, of the Exchange Act, state securities or "blue
sky" laws ("Blue Sky Laws") and state takeover laws, the pre-merger notification
requirements of the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, and the rules and regulations promulgated thereunder (the "HSR Act"),
the Foreign Ownership, Control and Influence regulations of the U.S. Department
of Defense and filing of the Certificate of Merger pursuant to Delaware Law, and
(ii) where failure to obtain such consents, approvals, authorizations or
permits, or to make such filings or notifications, would not prevent or delay
consummation of the Offer or the Merger, or otherwise prevent the Company from
performing its obligations under this Agreement, and would not, individually or
in the aggregate, have a Material Adverse Effect.

         SECTION 3.06 Compliance. Except as set forth in Section 3.06 of the
Disclosure Schedule, neither the Company nor any Subsidiary is in default or
violation of (i) any law, rule, regulation, order, judgment or decree applicable
to the Company or any Subsidiary or by which any property or asset of the
Company or any Subsidiary is bound or subject or (ii) any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which the Company or any Subsidiary is a party or by
which the Company or any Subsidiary or any property or asset of the Company or
any Subsidiary is bound or affected, except for any such defaults or violations
that would not, individually or in the aggregate, have a Material Adverse
Effect.

         SECTION 3.07 SEC Filings; Financial Statements. (a) The Company has
filed all forms, reports and documents required to be filed by it with the SEC
since December 31, 1994, and has heretofore delivered or made available to
Parent, in the form filed with the SEC, (i) its Annual Reports on Form 10-K for
the fiscal years ended December 31, 1994, 1995 and 1996, respectively, (ii) its
Quarterly Report on Form 10-Q for the period ended March 31, 1997, (iii) all
proxy statements relating to the Company's meetings of stockholders (whether
annual or special) held since December 31, 1994 and (iv) all other forms,
reports and other registration statements (other than Quarterly Reports on Form
10-Q not referred to in clause (ii) above) filed by the Company with the SEC
since December 31, 1994 (the forms, reports and other documents referred to in
clauses (i), (ii), (iii) and (iv) above being referred to herein, collectively,
as the "SEC Reports"). The SEC Reports (i) were prepared in accordance with the
requirements of the Securities Act of 1933, as amended (the "Securities Act"),
and the Exchange Act, as the case may be, and the rules and regulations
promulgated thereunder and (ii) did not, at the time they were filed (or at the
effective date thereof with respect to registration statements under the
Securities Act), contain any untrue statement of a material fact or omit to
state a material fact required to be stated therein or necessary in order to
make the statements made therein, in the light of the circumstances under which
they were made, not  




                                      13
<PAGE>   19


misleading. No Subsidiary is required to file any form, report or other document
with the SEC.

         (b) Each of the consolidated financial statements (including, in each
case, any notes thereto) contained in the SEC Reports was prepared in accordance
with United States generally accepted accounting principles applied on a
consistent basis ("GAAP") throughout the periods indicated (except as may be
indicated in the notes thereto) and each fairly presents the consolidated
financial position, results of operations and changes in stockholders equity and
cash flows of the Company and the consolidated Subsidiaries as at the respective
dates thereof and for the respective periods indicated therein (subject, in the
case of unaudited statements, to normal and recurring year-end adjustments which
were not and are not expected, individually or in the aggregate, to have a
Material Adverse Effect).

         (c) Except as and to the extent set forth on the consolidated balance
sheet of the Company and the consolidated Subsidiaries as at December 31, 1996
including the notes thereto (the "1996 Balance Sheet"), in Section 3.07 of the
Disclosure Schedule or in any SEC Report filed by the Company after December 31,
1996, neither the Company nor any Subsidiary has any liability or obligation of
any nature (whether accrued, absolute, contingent or otherwise) that would be
required to be reflected on a balance sheet, or in the notes thereto, prepared
in accordance with GAAP, except for liabilities and obligations incurred in the
ordinary course of business consistent with past practice since December 31,
1996.

         (d) The Company has heretofore furnished or made available to Parent
complete and correct copies of all amendments and modifications (if any) that
have not been filed by the Company with the SEC to all agreements, documents and
other instruments that previously had been filed by the Company with the SEC and
are currently in effect.

         SECTION 3.08 Absence of Certain Changes or Events. Since December 31,
1996, except as set forth in Section 3.08 of the Disclosure Schedule or as
contemplated by this Agreement or disclosed in any SEC Report filed since
December 31, 1996 and prior to the date of this Agreement, the Company and the
Subsidiaries have conducted their businesses only in the ordinary course and in
a manner consistent with past practice and, since December 31, 1996, there has
not been (i) any change in the business, operations, properties, financial
condition, assets or liabilities (including, without limitation, contingent
liabilities) of the Company or any Subsidiary having, individually or in the
aggregate, a Material Adverse Effect, (ii) any damage, destruction or loss
(whether or not covered by insurance) with respect to any property or asset of
the Company or any Subsidiary having, individually or in the aggregate, a
Material Adverse Effect, (iii) any material change by the Company in its
accounting methods, principles or practices, (iv) any material revaluation by
the Company of any asset (including, without limitation, any writing down of the
value of inventory or writing off of notes or accounts receivable), (v) any
failure by the Company to revalue any asset in accordance with GAAP, (vi) any
entry by the Company or any Subsidiary into any commitment or transaction
material to the Company and the Subsidiaries taken as a whole, 


                                      14
<PAGE>   20



(vii) any declaration, setting aside or payment of any dividend or distribution
in respect of any capital stock of the Company or any redemption, purchase or
other acquisition of any of its securities, (viii) any increase in or
establishment of any bonus, insurance, severance, deferred compensation,
pension, retirement, profit sharing, stock option (including, without
limitation, the granting of stock options, stock appreciation rights,
performance awards or restricted stock awards), stock purchase or other employee
benefit plan, or any other increase in the compensation payable or to become
payable to any officers or key employees of the Company or any Subsidiary,
except in the ordinary course of business consistent with past practice, or (ix)
any entering into, renewal, modification or extension of, any contract,
arrangement or agreement with any other party having, individually or in the
aggregate, a Material Adverse Effect.

         SECTION 3.09 Absence of Litigation. Except as set forth in Section 3.09
of the Disclosure Schedule or as disclosed in the SEC Reports filed prior to the
date of this Agreement, (a) there is no claim, action, proceeding or
investigation pending or, to the knowledge of the Company, threatened against
the Company or any Subsidiary, or any property or asset of the Company or any
Subsidiary, before any court, arbitrator or administrative, governmental or
regulatory authority or body, domestic or foreign, which (i) individually or in
the aggregate, would have a Material Adverse Effect or (ii) seeks to, or is
reasonably likely to, delay or prevent the consummation of any Transaction and
(b) as of the date hereof, neither the Company nor any  Subsidiary nor any
property or asset of the Company or any Subsidiary is subject to any order,
writ, judgment, injunction, decree, determination or award having, individually
or in the aggregate, a Material Adverse Effect.

         SECTION 3.10 Employee Benefit Plans. (a) Section 3.10(a) of the
Disclosure Schedule contains a true and complete list of (i) all employee
benefit plans (within the meaning of Section 3(3) of the Employee Retirement
Income Security Act of 1974, as amended ("ERISA")) and all bonus, stock option,
stock purchase, restricted stock, incentive, deferred compensation, retiree
medical or life insurance, supplemental retirement or severance plans, programs
or policies, and all employment, termination or severance contracts to which the
Company or any Subsidiary is a party, with respect to which the Company or any
Subsidiary has any obligation or which are maintained, contributed to or
sponsored by the Company or any Subsidiary for the benefit of any current or
former employee, officer or director of the Company or any Subsidiary
(collectively, the "Plans") and (ii) each employee benefit plan for which the
Company or any Subsidiary could incur liability under Section 4069 of ERISA in
the event such plan were terminated, or under Section 4212(c) of ERISA, or in
respect of which the Company or any Subsidiary remains secondarily liable under
Section 4204 of ERISA. Except as set forth in Section 3.10(a) of the Disclosure
Schedule, no Plan is a "defined benefit plan" within the meaning of Section
3(35) of ERISA and no Plan is subject to Part IV of ERISA. The Company has
previously furnished or made available to Parent a true and complete copy of
each Plan and a true and complete copy of each material document prepared in
connection with each Plan, including, without limitation, to the extent
applicable (i) a copy of each trust or other funding arrangement, (ii) each
summary plan description and summary 



                                       15
<PAGE>   21


of material modifications, (iii) the most recently filed Internal Revenue
Service ("IRS") Form 5500, (iv) the most recently received IRS determination
letter for each such Plan, and (v) the most recently prepared financial
statement in connection with each such Plan. Except as set forth in Section
3.10(a) of the Disclosure Schedule, neither the Company nor any Subsidiary has
made a general written announcement or entered into an agreement (i) to create
or adopt a new benefit plan or (ii) except in the ordinary course of business
consistent with past practice or as required by applicable law, to amend any
Plan.

         (b) All Plans subject to Parts 2, 3 and 4 of Subtitle A, Title I of
ERISA, other than "multiemployer plans" ("Multiemployer Plans"), within the
meaning of Section 3(37) of ERISA (the "ERISA Plans"), are in compliance with
ERISA, except for such non-compliance which would not have, individually or in
the aggregate, a Material Adverse Effect. Except as set forth in Section 3.10 of
the Disclosure Schedule, each ERISA Plan which is an "employee pension benefit
plan" within the meaning of Section 3(2) of ERISA ("Pension Plan") and which is
intended to be qualified under Section 401(a) of the Internal Revenue Code of
1986, as amended (the "Code") has received a favorable determination letter from
the IRS, and there are no circumstances likely to result in revocation of any
such favorable determination letter which would have, individually or in the
aggregate, a Material Adverse Effect. There is no litigation pending or, to the
knowledge of the Company, threatened relating to the ERISA Plans which would
have, individually or in the aggregate, a Material Adverse Effect. Neither the
Company nor any of the Subsidiaries has engaged in a transaction with respect to
any ERISA Plan that, assuming the taxable period of such transaction expired as
of the date thereof, insofar as may be reasonably foreseen, is likely to subject
the Company or any of the Subsidiaries to a tax or penalty imposed by either
Section 4975 of the Code or Section 502(i) of ERISA in an amount which would
have, individually or in the aggregate, a Material Adverse Effect.

         (c) Neither the Company nor any of the Subsidiaries has any outstanding
liability under Subtitle C or D of Title IV of ERISA with respect to any
ongoing, frozen or terminated "single-employer plan", within the meaning of
Section 4001(a)(15) of ERISA, currently or formerly maintained by any of them,
or the single-employer plan of any entity which is considered one employer with
the Company under Section 4001 of ERISA or Section 414 of the Code (an "ERISA
Affiliate"). Neither the Company nor any of the Subsidiaries presently
contributes to a Multiemployer Plan, nor has it contributed to a Multiemployer
Plan within the past five calendar years. No notice of a "reportable event",
within the meaning of Section 4043 of ERISA for which the 30 day reporting
requirement has not been waived, has been required to be filed for any Pension
Plan within the 12-month period ending on the date hereof.

         (d) All contributions required to be made under the terms of any ERISA
Plan have been timely made, except for such failures which, individually or in
the aggregate, would not have a Material Adverse Effect. No Pension Plan has an
"accumulated funding deficiency" (whether or not waived) within the meaning of
Section 412 of the Code or Section 302 of 


                                       16
<PAGE>   22


ERISA. Neither the Company nor any of the Subsidiaries has provided, or is
required to provide, security to any Pension Plan or to any single-employer plan
of an ERISA Affiliate pursuant to Section 401(a)(29) of the Code.

         (e) Under each Pension Plan which is a single-employer plan, as of the
last day of the most recent plan year ended prior to the date hereof, the
present value of all accrued "benefit liabilities", within the meaning of
Section 4001(a)(16) of ERISA (as determined on the basis of the actuarial
assumptions and methods contained in the Plan's most recent actuarial
valuation), did not exceed the then current value of the assets of such Plan.

         (f) Except as set forth in Section 3.10(f) of the Disclosure Schedule,
neither the Company nor any of the Subsidiaries has any obligation for retiree
health and life benefits under any ERISA Plan.

         (g) Except as set forth in Section 3.10(g) of the Disclosure Schedule,
neither the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will (i) result in any payment of severance or
unemployment compensation becoming due to any director or any employee of the
Company or any of the Subsidiaries under any Plan or otherwise from the Company
or any of the Subsidiaries, (ii) increase any benefits otherwise payable under
any Plan, or (iii) result in any acceleration of the time of payment or vesting
of any such benefit.

         (h) Except as disclosed in Section 3.10(h) of the Disclosure Schedule,
the Company and the Material Subsidiaries do not have any unfunded liabilities
under pension, retirement or other employee benefit plans, programs or
arrangements maintained outside the United States by the Company or any of the
Material Subsidiaries for the employees thereof, the payment of which by the
Company or such Material Subsidiary, individually or in the aggregate, would
have a Material Adverse Effect.

         SECTION 3.11 Labor Matters. Except as set forth in Section 3.11(a) of
the Disclosure Schedule and except for those matters that, individually or in
the aggregate, would not have a Material Adverse Effect, (i) there are no
controversies pending or, to the knowledge of the Company, threatened between
the Company or any Subsidiary and any of their respective employees; (ii)
neither the Company nor any Subsidiary has breached or otherwise failed to
comply with any provision of any collective bargaining agreement or other labor
union contract applicable to persons employed by the Company or any Subsidiary
and there are no grievances outstanding against the Company or any Subsidiary
under any such agreement or contract; (iii) there are no unfair labor practice
complaints pending against the Company or any Subsidiary before the National
Labor Relations Board or any current union representation questions involving
employees of the  Company or any Subsidiary; and (iv) there is no strike,
slowdown, work stoppage or lockout, or, to the knowledge of the Company, threat
thereof, by or with respect to any employees of the Company or any Subsidiary.
Section 3.11(b) of the Disclosure Schedule sets forth each collective bargaining
agreement or other labor union 



                                      17

<PAGE>   23


contract applicable to persons employed by the Company or any domestic
Subsidiary and any other material collective bargaining agreement or labor
contract applicable to persons employed by any foreign Subsidiary. To the
knowledge of the Company, there are no activities or proceedings of any labor
union to organize any employees of the Company or any Subsidiary.

         SECTION 3.12 Offer Documents; Schedule 14D-9; Proxy Statement. None of
the Schedule 14D-9, the information supplied by the Company for inclusion in the
Offer Documents or the Note Tender Offer Documents or the information to be
filed by the Company in connection with the Offer pursuant to Rule 14f-1
promulgated under the Exchange Act (the "Information Statement") shall, at the
respective times the Schedule 14D-9, the Offer Documents, the Note Tender Offer
Documents, the Information Statement or any amendments or supplements thereto
are filed with the SEC or are first published, sent or given to stockholders of
the Company, as the case may be, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they are made, not misleading. The proxy statement to be sent to the
stockholders of the Company in connection with the Special Stockholders' Meeting
(as defined in Section 6.01 hereof) (such proxy statement, as amended or
supplemented, being referred to herein as the "Proxy Statement") shall not, at
the date the Proxy Statement is first mailed to stockholders of the Company or
at the time of the Special Stockholders' Meeting and the Effective Time, and,
with respect to the Information Statement at the time Shares are accepted for
payment in the Offer and with respect to the Note Tender Offer at the time the
Notes (and related Consents) are accepted for payment in the Note Tender Offer,
be false or misleading with respect to any material fact, or omit to state any
material fact required to be stated therein or necessary in order to make the
statements made therein, in the light of the circumstances under which they are
made, not misleading or, with respect to the Proxy Statement, necessary to
correct any statement in any earlier communication with respect to the
solicitation of proxies for the Special Stockholders' Meeting which shall have
become false or misleading. Notwithstanding the foregoing, the Company makes no
representation or warranty with respect to any information supplied by Parent,
Purchaser or any of their representatives which is contained in any of the
foregoing documents or the Offer Documents or the Note Tender Offer Documents.
The Schedule 14D-9, the Information Statement and the Proxy Statement shall
comply in all material respects as to form with the requirements of the Exchange
Act and the rules and regulations thereunder.

         SECTION 3.13 Tangible Property; Real Property and Leases. (a) The
Company and the Subsidiaries have sufficient title to all their tangible
properties and assets to conduct their respective businesses as currently
conducted or as contemplated to be conducted, with only such exceptions as,
individually or in the aggregate, would not have a Material Adverse Effect.

         (b) No parcel of real property owned or leased by the Company is
subject to any governmental decree or order to be sold nor is being condemned,
expropriated or otherwise taken by any public authority with or without payment
of compensation therefor, nor, to the 



                                     18
<PAGE>   24


knowledge of the Company, has any such condemnation, expropriation or taking
been proposed.

         (c) All leases of real property leased for the use or benefit of the
Company or any Subsidiary to which the Company or any Subsidiary is a party
requiring rental payments in excess of U.S. $100,000 during the period of the
lease and all amendments and modifications thereto are in full force and effect
and have not been modified or amended, and there exists no default under 
any such lease by the Company or any Subsidiary, nor any event which with notice
or lapse of time or both would constitute a default thereunder by the Company or
any Subsidiary, except as, individually or in the aggregate, would not have a
Material Adverse Effect or as set forth in Section 3.13 of the Disclosure
Schedule.

         SECTION 3.14 Trademarks, Patents and Copyrights. Except as set forth in
Section 3.14(a) of the Disclosure Schedule, the Company and the Subsidiaries own
or possess adequate licenses or other valid rights to use all patents, patent
rights, trademarks, trademark rights, trade names, trade dress, trade name
rights, copyrights, servicemarks, trade secrets, applications for trademarks and
for servicemarks, mask works, know-how and other proprietary rights and
information used or held for use in connection with the business of the Company
and the Subsidiaries as conducted since December 31, 1996, as currently
conducted or as contemplated to be conducted, and the Company is unaware of any
assertion or claim challenging the validity of any of the foregoing which,
individually or in the aggregate, would have a Material Adverse Effect. Section
3.14(b) of the Disclosure Schedule lists each material patent owned by the
Company or any Subsidiary and specifies the number and date of each such patent.
Section 3.14(c) of the Disclosure Schedule lists each agreement pursuant to
which a material patent is licensed to the Company or any Material Subsidiary as
licensee for use in the business of the Company and the Subsidiaries as
currently conducted. The conduct of the business of the Company and the
Subsidiaries as conducted since December 31, 1996, as currently conducted and as
contemplated to be conducted did not, does not and will not conflict in any way
with any patent, patent right, license, trademark, trademark right, trade dress,
trade name, trade name right, service mark, mask work or copyright of any third
party except for conflicts that, individually or in the aggregate, would not
have a Material Adverse Effect.

         SECTION 3.15 Taxes. Except as set forth in Section 3.15 of the
Disclosure Schedule or as otherwise previously disclosed to Parent:

         (a) The Company and the Subsidiaries, and each affiliated group (within
the meaning of Section 1504 of the Internal Revenue Code of 1986, as amended
(the "Code")) or combined or unitary group of which the Company or any
Subsidiary is or has been a member, has timely filed all federal income Tax
Returns (as defined below), and all other material Tax Returns required to be
filed by them. All such Tax Returns are true and correct in all material
respects. Except to the extent adequately reserved for in accordance with GAAP,
all material Taxes (as defined below) due and payable by the Company and the
Subsidiaries have been timely paid. The most recent consolidated financial
statements contained in the SEC Reports 



                                      19

<PAGE>   25



reflect an adequate reserve in accordance with GAAP for all Taxes payable by the
Company and its Subsidiaries for all taxable periods and portions thereof
through the date of such financial statements.

         (b) No material deficiencies for any Taxes have been proposed, asserted
or assessed against the Company or any of the Subsidiaries that have not been
fully paid or adequately provided for in the appropriate financial statements of
the Company and its Subsidiaries, no waivers of the time to assess any Taxes are
outstanding, and no power of attorney granted by the Company or any Subsidiary
with respect to any Taxes is currently in force. No material issues relating to
Taxes have been raised in writing (or, in the case of the presently pending
Federal income tax audit of the Company and the Subsidiaries, verbally to the
knowledge of the Company's Vice President of Taxes) by any governmental
authority during any presently pending audit or examination.

         (c) There are no material liens or encumbrances for Taxes on any of the
assets of the Company or the Subsidiaries (other than for current taxes not yet
due and payable).

         (d) The Company and the Subsidiaries have complied in all material
respects with all applicable laws, rules and regulations relating to the payment
and withholding of Taxes.

         (e) None of the Company or the Subsidiaries has filed a consent under
Section 341(f) of the Code.

         (f) None of the Company or the Subsidiaries is a party to any agreement
that could obligate it to make any payments that would not be deductible by
reason of Section 280G of the Code.

         (g) Neither the Company nor, since the date of its acquisition by the
Company, any Material Subsidiary is a party to any tax allocation, tax sharing
agreement, any closing agreement or similar agreement relating to Taxes with any
taxing authority of the Company.

         (h) No federal, state, local or foreign audits or other administrative
proceedings or court proceedings are presently pending with regard to any
federal income or material state, local or foreign Taxes or Tax Returns of the
Company or any of the Subsidiaries and neither the Company nor any of the
Subsidiaries has received a written notice of any pending audit or proceeding.

         (i) Neither the Company nor, since the date of its acquisition by the
Company, any Material Subsidiary has agreed to or is required to make any
material adjustment under Section 481(a) of the Code.

         (j) To the knowledge of the Company, no property owned by the Company
or any Subsidiary (i) is property required to be treated as being owned by
another person pursuant to 


                                      20

<PAGE>   26


the provisions of Section 168(f)(8) of the Internal Revenue Code of 1954, as
amended and in effect immediately prior to the enactment of the Tax Reform Act
of 1986; or (ii) constitutes "tax exempt use property" within the meaning of
Section 168(h)(1) of the Code.

         (k) The Company has not been (and will not be) a United States real
property holding corporation within the meaning of Section 897(c)(2) of the Code
during the 5-year period ending on the consummation of the Offer.

         (l) To the knowledge of the Company, neither the Company nor any
Subsidiary has participated in or cooperated with an international boycott
within the meaning of Section 999 of the Code.

         (m) The Company estimates that, to its knowledge, the fair market value
of the assets of the Company and the Subsidiaries, in the aggregate, is more
than the aggregate adjusted basis of such assets, determined as of the date of
this Agreement.

         (n) For purpose of this Agreement, (A) the terms "Tax" or "Taxes" shall

         Parent and Purchaser hereby, jointly and severally, represent and
warrant to the Company that:

         SECTION 4.01 Corporate Organization. Each of Parent and Purchaser is a
corporation duly organized, validly existing and in good standing under the laws
of the jurisdiction of its incorporation and has the requisite power and
authority and all necessary governmental approvals to own, lease and operate its
properties and to carry on its business as it is now being conducted, except
where the failure to be so organized, existing or in good standing or to have
such power, authority and governmental approvals would not, individually or in
the aggregate, have a material adverse effect on the business, operations,
financial condition, assets or liabilities (including, without limitation,
contingent liabilities) of Parent and Purchaser and their respective
subsidiaries, taken as a whole.

         SECTION 4.02 Authority Relative to This Agreement. Each of Parent and
Purchaser has all necessary corporate power and authority to execute and deliver
this Agreement, to perform its obligations hereunder and to consummate the
Transactions. The execution and delivery of this Agreement by Parent and
Purchaser and the consummation by Parent and Purchaser of the Transactions have
been duly and validly authorized by all necessary corporate action and no other
corporate proceedings on the part of Parent or Purchaser are necessary to
authorize this Agreement or to consummate the Transactions (other than with
respect to the Merger, the filing of the Certificate of Merger). This Agreement
has been duly and validly executed and delivered by Parent and Purchaser and,
assuming the due authorization, execution and delivery by the Company,
constitutes a legal, valid and binding obligation of each of Parent and
Purchaser enforceable against each of Parent and Purchaser in accordance with
its terms.

         SECTION 4.03 No Conflict; Required Filings and Consents. (a) The
execution and delivery of this Agreement by Parent and Purchaser do not, and the
performance of this Agreement by Parent and Purchaser will not, (i) conflict
with or violate the Articles of Incorporation or Bylaws (or equivalent
documents) of either Parent or Purchaser, (ii) assuming that required filings
under the HSR Act are made by the appropriate parties, conflict with or violate
any law, rule, regulation, order, judgment or decree applicable to Parent or
Purchaser or by which any property or asset of either of them is bound or
affected, or (iii) result in any breach of or constitute a default (or an event
which with notice or lapse of time or both would become a default) under, or
give to others any rights of termination, amendment, acceleration or
cancellation of, or result in the creation of a lien or other encumbrance on any
property or asset of Parent or Purchaser pursuant to, any note, bond, mortgage,
indenture, contract, agreement, lease, license, permit, franchise or other
instrument or obligation to which Parent or Purchaser is a party or by which
Parent or Purchaser or any property or asset of either of 



                                      24
<PAGE>   30


them is bound or affected, except, in cases of (ii) and (iii), for any such
conflicts, violations, breaches, defaults or other occurrences which would not,
individually or in the aggregate, have a material adverse effect on the
business, operations, financial condition, assets or liabilities (including,
without limitation, contingent liabilities) of Parent or Purchaser and their
respective subsidiaries, taken as a whole.

         (b) The execution and delivery of this Agreement by Parent and
Purchaser do not, and the performance of this Agreement by Parent and Purchaser
will not, require any consent, approval, authorization or permit of, or filing
with or notification to, any governmental or  regulatory authority, domestic or
foreign, except (i) for applicable requirements, if any, of the Exchange Act,
Blue Sky Laws and state takeover laws, the HSR Act, and the filing of the
Certificate of Merger as required by Delaware Law and (ii) where failure to
obtain such consents, approvals, authorizations or permits, or to make such
filings or notifications, would not prevent or delay consummation of the Offer
or the Merger, or otherwise prevent Parent or Purchaser from performing their
respective obligations under this Agreement.

         SECTION 4.04 Financing. Parent has, or has commitments to obtain,
sufficient funds to permit Purchaser (i) to acquire all the outstanding Shares
in the Offer and the Merger and (ii) to acquire all of the Notes (and obtain all
of the related Consents) in the Note Tender Offer, written evidence of which has
been provided to the Company.

         SECTION 4.05 Offer Documents; Proxy Statement. Neither the Offer
Documents nor the Note Tender Offer Documents will, at the time such documents
are filed with the SEC or are first published, sent or given to stockholders of
the Company, as the case may be, contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary in
order to make the statements made therein, in the light of the circumstances
under which they are made, not misleading. The information supplied by Parent
for inclusion in the Schedule 14D-9, the Information Statement or the Proxy
Statement will not, on the date such document (or any amendment or supplement
thereto) is first mailed to stockholders of the Company, with respect to the
Information Statement, at the time Shares are accepted for payment in the Offer

related Consents) are accepted for payment in the Note Tender Offer, and with
respect to the Proxy Statement at the time of the Special Stockholders' Meeting
and at the Effective Time, contain any statement which, at such time and in
light of the circumstances under which it is made, is false or misleading with
respect to any material fact, or omits to state any material fact required to be
stated therein or necessary in order to make the statements therein not false or
misleading or necessary to correct any statement in any earlier communication
with respect to the solicitation of proxies for the Special Stockholders'
Meeting which shall have become false or misleading. Notwithstanding the
foregoing, Parent and Purchaser make no representation or warranty with respect
to any information supplied by the Company or any of its representatives which
is contained in any of the foregoing documents or the Offer Documents or the
Note Tender Offer Documents. The Offer Documents and the Note Tender Offer
Documents shall comply in all material respects as to form with the 

                                      25

                              ADDITIONAL AGREEMENTS

         SECTION 6.01 Special Stockholders' Meeting. The Company, acting through
the Board, shall, in accordance with applicable law and its Constituent
Documents, unless not required under applicable "short-form" merger provisions
of Delaware Law, (i) duly call, give notice of, convene and hold a special
meeting of its stockholders as soon as practicable following consummation of the
Offer for the purpose of considering and taking action on this Agreement and the
transactions contemplated hereby (the "Special Stockholders' Meeting") and (ii)
subject to its fiduciary duties under applicable law as advised by independent
counsel, (A) include in the Proxy Statement the unanimous recommendation of the
Board that the stockholders of the Company approve and adopt this Agreement and

reasonable efforts to obtain such approval and adoption. At the Special
Stockholders' Meeting (or by consent if a stockholders meeting is not required),
Parent and Purchaser shall cause all Shares then owned by them and their
subsidiaries to be voted in favor of the approval and adoption of this Agreement
and the Transactions, including, without limitation, the Merger.

         SECTION 6.02 Proxy Statement. As soon as practicable following
consummation of the Offer, the Company shall file the Proxy Statement with the
SEC under the Exchange Act, unless the Special Stockholders' Meeting is not

Parent, Purchaser and the Company shall cooperate with each other in the
preparation of the Proxy Statement, and the Company shall notify Parent of the
receipt of any comments of the SEC with respect to the Proxy Statement and of
any requests by the SEC for any amendment or supplement thereto or for
additional information and shall provide to Parent promptly copies of all
correspondence between the Company or any representative of the 



                                     28
<PAGE>   34


Company and the SEC. The Company shall give Parent and its counsel the
opportunity to review the Proxy Statement prior to its being filed with the SEC
and shall give Parent and its counsel the opportunity to review all amendments
and supplements to the Proxy Statement and all responses to requests for
additional information and replies to comments prior to their being filed with,

reasonable efforts, after consultation with the other parties hereto, to respond
promptly to all such comments of and requests by the SEC and to cause the Proxy
Statement and all required amendments and supplements thereto to be mailed to
the holders of Shares entitled to vote at the Special Stockholders' Meeting at
the earliest practicable time.

         SECTION 6.03 Company Board Representation; Section 14(f). (a) Promptly
upon the purchase by Purchaser of Shares pursuant to the Offer, and from time to
time thereafter, Purchaser shall be entitled to designate up to such number of
directors, rounded up to the next whole number, on the Board as shall give
Purchaser representation on the Board equal to the product of the total number
of directors on the Board (giving effect to the directors elected pursuant to
this sentence) multiplied by the percentage that the aggregate number of Shares
beneficially owned by Purchaser or any affiliate of Purchaser at such time bears
to the total number of Shares then outstanding, and the Company shall, at such
time, promptly take all actions necessary to cause Purchaser's designees to be
elected as directors of the Company, including increasing the size of the Board
or securing the resignations of incumbent directors or both. At such times, the
Company shall use all reasonable efforts to cause persons designated by
Purchaser to constitute the same percentage as persons designated by Purchaser
shall constitute of the Board with respect to (i) each committee of the Board
(some of whom may be required to be independent as required by applicable law or
requirements of the New York Stock Exchange), (ii) each board of directors of
each Subsidiary and (iii) each committee of each such board, in each case only
to the extent permitted by applicable law. Notwithstanding the foregoing, until
the time Purchaser acquires a majority of the then outstanding Shares on a fully
diluted basis, the Company shall use all reasonable efforts to ensure that all
the members of the Board and each committee of the Board and such boards and
committees of the Subsidiaries as of the date hereof who are not employees of
the Company shall remain members of the Board and of such boards and committees.

         (b) The Company shall promptly take all actions required pursuant to
Section 14(f) of the Exchange Act and Rule 14f-1 promulgated thereunder in order
to fulfill its obligations under this Section 6.03 and shall include the
Information Statement containing such information with respect to the Company
and its officers and directors as is required under Section 14(f) and Rule 14f-1

Purchaser shall supply to the Company and be solely responsible for any
information with respect to either of them and their nominees, officers,
directors and affiliates required by such Section 14(f) and Rule 14f-1.

         (c) Following the election or appointment of designees of Purchaser
pursuant to this Section 6.03, prior to the Effective Time, any amendment of
this Agreement or the Constituent 



                                      29
<PAGE>   35


Documents of the Company, any termination of this Agreement by the Company, any
extension by the Company of the time for the performance of any of the
obligations or other acts of Parent or Purchaser or waiver of any of the
Company's rights hereunder shall require the concurrence of a majority of the
directors of the Company then in office who neither were designated by Purchaser
nor are employees of the Company or if no such directors are then in office, no
such amendment, termination, extension or waiver shall be effected which is
materially adverse to the holders of Shares (other than Parent and its
subsidiaries).

         SECTION 6.04 Access to Information; Confidentiality. (a) From the date
hereof to the consummation of the Offer, the Company shall, and shall cause the
Subsidiaries to, afford the officers, employees and agents of Parent and
Purchaser and persons providing or committing to provide Parent or Purchaser

the officers, employees, agents, properties, offices, plants and other
facilities, books and records of the Company and each Subsidiary, and shall
furnish Parent and Purchaser and persons providing or committing to provide
Parent or Purchaser with financing for the Transactions with all financial,
operating and other data and information as Parent or Purchaser, through its
officers, employees or agents, may reasonably request.

pursuant to this Section 6.04 shall be kept confidential, by Purchaser, by
Parent and by any other party which is to be afforded access pursuant to Section
6.04(a), in accordance with the confidentiality agreement, dated April 25, 1997
(the "Confidentiality Agreement"), between Parent and the Company.

any Subsidiary shall, directly or indirectly, through any officer, director,
agent or otherwise, solicit, initiate or encourage the submission of any
proposal or offer from any person relating to any acquisition or purchase of all
or any material portion of the assets of, or any equity interest in, the Company
or any Material Subsidiary or any business combination with the Company or any
Material Subsidiary or participate in any negotiations regarding, or furnish to
any other person any information with respect to, or otherwise cooperate in any
way with, or assist or participate in, facilitate or encourage, any effort or
attempt by any other person to do or seek any of the foregoing and the Company
immediately shall cease and cause to be terminated all existing discussions or
negotiations with any parties conducted heretofore with respect to any of the
foregoing. Notwithstanding the foregoing or any other provision hereof, nothing
shall prohibit the Board from furnishing information to, or entering into
discussions or negotiations with, any person in connection with an unsolicited
(from the date of this Agreement) proposal in writing by such person to acquire
the Company pursuant to a merger, consolidation, share exchange, business
combination or other similar transaction or to acquire all or substantially all
of the assets of the Company or any of its Subsidiaries, if, and only to the
extent that, (i) the Board, after consultation with independent legal counsel
(which may include its regularly engaged independent legal counsel), determines
in good faith that such action is required for the Board to comply with its
fiduciary duties to stockholders imposed by

Delaware Law and (ii) prior to furnishing such information to, or entering into
discussions or negotiations with, such person the Company uses its reasonable
efforts to obtain from such person an executed confidentiality agreement on
terms no less favorable to the Company than those contained in the
Confidentiality Agreement. The Company shall notify Parent promptly if any such
proposal or offer, or any inquiry or contact with any person with respect
thereto, is made. The Company agrees not to release any third party from, or
waive any provision of, any confidentiality or, subject to the fiduciary duties
of the Board, standstill agreement to which the Company is or may become a
party.

         SECTION 6.06 Employee Benefits Matters; Employment Agreements. Annex C
hereto sets forth certain agreements among the parties hereto with respect to
the Plans and other employee benefits matters.

         SECTION 6.07 Directors' and Officers' Indemnification and Insurance.
(a) The Certificate of Incorporation and Bylaws of the Surviving Corporation
shall contain provisions no less favorable with respect to indemnification than
are set forth in Article XIII of the Bylaws of the Company, which provisions
shall not be amended, repealed or otherwise modified for a period of six years
from the Effective Time in any manner that would affect adversely the rights
thereunder  of individuals who at any time from and after the date of this
Agreement and to and including the Effective Time were directors, officers,
employees, fiduciaries or agents of the Company in respect of acts or omissions
occurring at or prior to the Effective Time (including, without limitation, the
matters contemplated by this Agreement), unless such modification shall be
required by law. From and after the Purchaser's Election Date, the Company
shall not amend, repeal or otherwise modify the indemnification and advancement
of expenses provisions of Article XIII of the Bylaws of the Company or the
indemnification or advancement of expenses provisions in the Constituent
Documents of any of the Subsidiaries in any manner that would adversely affect
the rights thereunder of individuals who at any time from and after the date of
this Agreement and to and including the Effective Time were directors,
officers, employees, fiduciaries or agents of the Company or any of the
Subsidiaries in respect of acts or omissions occurring at or prior to the
Effective Time (including, without limitation, the matters contemplated by this
Agreement), unless such modification is required by law.

         (b) The Company shall, to the fullest extent permitted under applicable
law, indemnify and hold harmless, and, after the Effective Time, Parent and the
Surviving Corporation shall, to the fullest extent permitted under applicable
law, indemnify and hold harmless, each present and former director, officer,
employee, fiduciary and agent of the Company and each Subsidiary (collectively,
the "Indemnified Parties") against all costs and expenses (including reasonable
attorneys' fees), judgments, fines, losses, claims, damages, liabilities and
settlement amounts paid in connection with any claim, action, suit, proceeding
or investigation (whether arising before or 


                                      31

<PAGE>   37


after the Effective Time), whether civil, criminal, administrative or
investigative, arising out of or pertaining to any act or omission in their
capacity as an officer, director, employee, fiduciary or agent, whether
occurring before or after the Effective Time, for a period of six years after
the date hereof (and shall pay any expenses in advance of the final disposition
of any such action or proceeding to each Indemnified Party to the fullest
extent permitted under Delaware Law, and, with respect to Indemnified Parties
who are or were directors or officers of the Company, upon receipt from the
Indemnified Party to whom expenses are advanced of any undertaking to repay
such advances required under Delaware Law). In the event of any such claim,
action, suit, proceeding or investigation, (i) the Company, Parent or the
Surviving Corporation, as the case may be, shall pay the reasonable fees and
expenses of counsel selected by the Indemnified Parties, which counsel shall be
reasonably satisfactory to the Company, Parent or the Surviving Corporation,
promptly after statements therefor are received (subject to the provision of an
undertaking as set forth in the prior sentence, if applicable) and (ii) the
Company, Parent and the Surviving Corporation shall cooperate in the defense of
any such matter; provided, however, that neither the Company, Parent nor the
Surviving Corporation (i) shall be liable for any settlement effected without
its written consent (which consent shall not be unreasonably withheld); or (ii)
shall be obligated pursuant to this Section 6.07(b) to pay the fees and
expenses of more than one counsel for all Indemnified Parties in any single
action except to the extent that two or more of such Indemnified Parties shall
have conflicting interests in the outcome of such action; and provided further
that, in the event that any claim for indemnification is asserted or made
within such six-year period, all rights to indemnification in respect of such
claim shall continue until the disposition of such claim.

         (c) The Company shall maintain in effect from and after the date of
this Agreement and to and including the Effective Time, and Parent shall cause
the Surviving Corporation from the Effective Time until six years thereafter to
maintain in effect, insurance coverage, if available, equivalent to that
provided by the directors' and officers' liability insurance policies currently
maintained by the Company with respect to matters occurring on or prior to the
Effective Time; provided, however, that the Surviving Corporation may substitute
therefor policies of at least the same coverage containing terms and conditions
which are not materially less favorable; and provided further that, in no event
shall the Surviving Corporation be required to expend pursuant to this Section
6.07(c) more than an amount per year equal to 250% of current annual premiums
paid by the Company for such insurance (which annual premiums the Company
represents to be approximately $300,000).

         (d) In the event the Company, Parent or the Surviving Corporation or
any of their respective successors or assigns (i) consolidates with or merges
into any other person and shall not be the continuing or surviving corporation
or entity of such consolidation or merger or (ii) transfers all or substantially
all of its properties and assets to any person, then, and in each such case,
proper provision shall be made so that the successors and assigns of the
Company, Parent or the Surviving Corporation, as the case may be, shall assume
the obligations set forth in this Section 6.07.

         SECTION 6.08 Notification of Certain Matters. The Company shall give
prompt notice to Parent, and Parent shall give prompt notice to the Company, of
(i) the occurrence or 

                                      32
<PAGE>   38


non-occurrence of any event the occurrence or non-occurrence of which causes
any representation or warranty contained in this Agreement to be untrue or
inaccurate in any material respect and (ii) any failure of the Company, Parent
or Purchaser, as the case may be, to comply with or satisfy any covenant,
condition or agreement to be complied with or satisfied by it hereunder;
provided, however, that the delivery of any notice pursuant to this Section
6.08 shall not limit or otherwise affect the remedies available hereunder to
the party receiving such notice.

         SECTION 6.09 Further Action; Reasonable Efforts. Upon the terms and
subject to the conditions hereof, each of the parties hereto shall (i) make
promptly its respective filings, and thereafter make any other required
submissions, under the HSR Act with respect to the Transactions and (ii) use all
reasonable efforts to take, or cause to be taken, all appropriate action, and to
do, or cause to be done, all things necessary, proper or advisable under
applicable laws and regulations to consummate and make effective the
Transactions, including, without limitation, using all reasonable efforts to
obtain all licenses, permits (including, without limitation, environmental
permits), consents, approvals, authorizations, qualifications and orders of
governmental authorities and parties to contracts with the Company and the
Subsidiaries as are necessary for the consummation of the Transactions and to
fulfill the conditions to the Offer, the Note Tender Offer and the Merger and
(iii) except as contemplated by this Agreement, use all reasonable efforts not
to take any action, or enter into any transaction, which would cause any of its
representations or warranties contained in this Agreement to be untrue or result
in a breach of any covenant made by it in this Agreement. In case at any time
after the Effective Time any further action is necessary or desirable to carry
out the purposes of this Agreement, the proper officers and directors of Parent
and the Company shall use all reasonable efforts to take all such action.

         SECTION 6.10 Public Announcements. Parent and the Company shall consult
with each other before issuing any press release or otherwise making any public
statements with respect to this Agreement or any Transaction and shall not issue
any such press release or make any such public statement prior to such
consultation, except as may be required by law or any listing agreement with a
national securities exchange or foreign securities exchange to which Parent or
the Company is a party.

         SECTION 6.11 Confidentiality Agreement. Assuming the Minimum Condition
has been satisfied, upon the acceptance for payment of Shares pursuant to the
Offer, the Confidentiality Agreement shall be deemed to have terminated without
further action by the parties thereto.

each party to effect the Merger shall be subject to the satisfaction at or prior
to the Effective Time of the following conditions:

         including, without limitation, the Merger, shall have been approved and
         adopted by the affirmative vote of the stockholders of the Company
         (unless the vote of the stockholders is not required by Delaware Law);

                  (b) HSR Act. Any waiting period (and any extension thereof)
         applicable to the consummation of the Merger under the HSR Act shall
         have expired or been terminated;

                  (c) No Order. No foreign, United States or state governmental
         authority or other agency or commission or foreign, United States or
         state court of competent jurisdiction shall have enacted, issued,
         promulgated, enforced or entered any law, rule, regulation, executive
         order, decree, injunction or other order (whether temporary,
         preliminary or permanent) which is then in effect and has the effect of
         making the acquisition of Shares by Parent or Purchaser or any
         affiliate of either of them or the consummation of the Merger illegal
         under applicable law or otherwise restricting, preventing or
         prohibiting under applicable law consummation of the Transactions;

                  (d) Offer. Purchaser or its permitted assignee shall have
         purchased all Shares validly tendered and not withdrawn pursuant to the
         Offer; provided, however, that neither Parent nor Purchaser shall be
         entitled to assert the failure of this condition if, in breach of this
         Agreement or the terms of the Offer, Purchaser fails to purchase any
         Shares validly tendered and not withdrawn pursuant to the Offer; and

                  (e) Note Tender Offer. The Supplemental Indenture shall have
         been entered into and Parent or its permitted assignee shall have
         purchased all Notes validly tendered and not withdrawn pursuant to the
         Note Tender Offer; provided, however, that Parent shall not be entitled
         to assert the failure of this condition if, in breach of this Agreement
         or the terms of the Note Tender Offer, Parent fails to purchase any
         Notes validly tendered and not withdrawn pursuant to the Note Tender
         Offer.

                        TERMINATION, AMENDMENT AND WAIVER

         SECTION 8.01 Termination. This Agreement may be terminated and the
Merger and the other Transactions may be abandoned at any time prior to the
Effective Time, notwithstanding any requisite approval and adoption of this
Agreement and the transactions contemplated hereby by the stockholders of the
Company:

                  (a) By mutual written consent duly authorized by the Boards of

         8.01(b) shall not be available to any party whose failure to fulfill
         any obligation under this Agreement has been the cause of, or resulted
         in, the failure of the Effective Time to occur on or before such date
         or (ii) any court of competent jurisdiction in the United States or
         other governmental authority shall have issued an order, decree, 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; or

                  (c) By Parent if (i) due to an occurrence or circumstance that

         commence the Offer within five business days following the date of
         public announcement of the execution of this Agreement, (B) failed to

         or Notes (and obtain related Consents) pursuant to the Offer or the
         Note Tender Offer, as the case may be, within 90 days following the
         commencement thereof; unless such action or inaction under (A), (B),
         (C) or (D) shall have been caused by or resulted from the failure of
         Parent or Purchaser to perform in any material respect any material
         covenant or agreement of either of them contained in this Agreement or
         the material breach by Parent or Purchaser of any material
         representation or warranty of either of them contained in this
         Agreement or (ii) prior to the purchase of Shares pursuant to the Offer
         or the Notes pursuant to the Note Tender Offer, the Board or any
         committee thereof shall have withdrawn or modified in a manner adverse
         to Purchaser or Parent its approval or recommendation of the Offer,
         this Agreement, the Merger or any other Transaction or shall have
         recommended another merger, consolidation, business combination with,
         or acquisition of, the

<PAGE>   41


         Company or its assets or another tender offer or exchange offer for 
         Shares, or shall have resolved to do any of the foregoing; or

                  (d) By the Company, upon approval of the Board if (i)
         Purchaser shall have (A) failed to commence the Offer within five
         business days following the date of public announcement of the
         execution of this Agreement, (B) failed to commence the Note Tender
         Offer within 10 business days following the date of public announcement
         of the execution of this Agreement, (C) terminated the Offer or the
         Note Tender Offer without having accepted any Shares or Notes (and
         without having obtained related Consents), as the case may be, for
         payment thereunder or (D) failed to pay for Shares pursuant to the
         Offer or the Notes (and obtain related Consents) pursuant to the Note
         Tender Offer within 90 days following the commencement thereof, unless
         such action or inaction under (A), (B), (C) or (D) shall have been
         caused by or resulted from the failure of the Company to perform in any
         material respect any material covenant or agreement of it contained in
         this Agreement or the material breach by the Company of any material
         representation or warranty of it contained in this Agreement or (ii)
         prior to the purchase of Shares pursuant to the Offer or the Notes
         pursuant to the Note Tender Offer, the Board shall have withdrawn or
         modified in a manner adverse to Purchaser or Parent its approval or
         recommendation of the Offer, this Agreement, the Merger or any other
         Transaction in order to approve the execution by  the Company
         of a definitive agreement providing for the acquisition of the Company
         or any of its assets by a sale, merger or other business combination
         or in order to approve a tender offer or exchange offer for Shares by
         a third party, in either case, as the Board determines in good faith
         that such action is required for the Board to comply with its
         fiduciary duties to stockholders, after consultation with its
         independent legal counsel and financial advisers, and is on terms more
         favorable to the Company's stockholders than the Offer and the Merger
         taken together; provided, however, that such termination under this
         clause (ii) shall not be effective until the Company has made payment
         to Parent of the Fee (as hereinafter defined) required to be paid
         pursuant to Section 8.03(a)(iv) and has deposited with a mutually
         acceptable escrow agent $2.0 million for reimbursement of Expenses (as
         hereinafter defined).

         SECTION 8.02 Effect of Termination. In the event of the termination of
this Agreement pursuant to Section 8.01, this Agreement shall forthwith become
void, and there shall be no liability on the part of any party hereto, except as
set forth in Sections 8.03 and 9.01, and nothing herein shall relieve any party
from liability for any breach hereof.

         SECTION 8.03 Fees and Expenses. (a) In the event that

                  (i)      any person (including, without limitation, the
         Company or any affiliate thereof), other than Parent or any affiliate
         of Parent, shall have become the beneficial owner of more than 20% of
         the then outstanding Shares, this Agreement shall have been terminated
         pursuant to Section 8.01 (other than pursuant to Section 8.01(c)(ii) or



                                       36
<PAGE>   42


         8.01(d)(ii)) and within 12 months of such termination a Third Party
         Acquisition (as defined hereinafter) shall occur; or

                  (ii)     any person shall have commenced, publicly proposed or
         communicated to the Company a proposal that is publicly disclosed for a
         tender or exchange offer for 25% or more of the then outstanding Shares
         (or which, assuming the maximum amount of securities that could be
         purchased, would result in any person beneficially owning 25% or more
         of the then outstanding Shares) or otherwise for the direct or indirect
         acquisition of the Company or all or substantially all of its assets
         for per Share consideration having a value greater than the Per Share
         Amount and (w) the Offer shall have remained open for at least 20
         business days, (x) the Minimum Condition shall not have been satisfied,
         (y) this Agreement shall have been terminated pursuant to Section 8.01
         (and other than pursuant to Section 8.01(c)(ii) or 8.01(d)(ii)) and (z)
         within 12 months of such termination a Third Party Acquisition shall
         occur; or

                  (iii)    if the Minimum Condition or the Requisite Consent
         Condition shall not have been satisfied on or prior to the date that is
         60 days from the date of commencment of the Offer, Parent desires to
         extend the Offer beyond such 60 day period but the Company declines to
         consent to such extension pursuant to Section 1.01, this Agreement is
         terminated pursuant to Section 8.01 (and other than pursuant to Section
         8.01(c)(ii) or 8.01(d)(ii)) and within 12 months of such termination a
         Third Party Acquisition shall occur; or

                  (iv)     this Agreement is terminated pursuant to Section
         8.01(c)(ii) or 8.01(d)(ii)

then, in any such event, provided that neither Parent nor Purchaser is in
material breach of its obligations under this Agreement, the Company shall pay
Parent promptly (but in no event later than one business day after (a) the
consummation of the Third Party Acquisition, with respect to the events 
described in clauses (i), (ii) or (iii), or (b) such termination with
respect to clause (iv)) a fee of U.S. $8 million (the "Fee"), which amount shall
be payable in immediately available funds, plus all Expenses.

         (b) Provided that neither Parent nor Purchaser is in material breach of
its obligations under this Agreement and Parent is not entitled to the Fee
pursuant to Section 8.03(a), if (i) this Agreement is terminated pursuant to
Section 8.01(c) due to the occurrence of the condition set forth in paragraph
(g) of Annex A or (ii) this Agreement is terminated pursuant to Section 8.01(c)
because of the occurrence of the condition set forth in paragraph (f) of Annex A
and such occurrence results from the failure of the representations and
warranties of the Company in this Agreement to be true and correct in accordance
with their respective terms, then, in either case (i) or (ii), the Company shall
promptly reimburse Parent and Purchaser for all Expenses.

         proposal or any other acquisition of Shares other than the
         Offer and the Merger or (B) the Board or any committee thereof shall
         have resolved to do any of the foregoing;

                  (f) (i)  any representation or warranty of the Company in the 
         Agreement shall not be true and correct; or

                      (ii) there shall have occurred, since the date of the
         Agreement, a change in the business, operations, financial condition,
         assets or liabilities of the Company or any Subsidiary

         with the effect that such failure of any such representation or
         warranty to be true and correct or such change, when taken together
         with all other such failures of such representations and warranties to
         be true and correct (both favorable and adverse) and all other such
         changes (both favorable and adverse), in the aggregate would have, a
         Material Adverse Effect; provided, however that, for the purpose of the
         foregoing condition, in determining whether any such representation or
         warranty is true or correct, any qualification as to materiality or
         Material Adverse Effect contained in any such representation and

         respect any material obligation or to comply in any material respect
         with any material agreement or material covenant of the Company to be
         performed or complied with by it under the Agreement;

                  (h) the Agreement shall have been terminated in accordance 
         with its terms; or

                  (i) Purchaser and the Company shall have agreed that Purchaser
         shall terminate the Offer or postpone the acceptance for payment of or
         payment for Shares thereunder; which, in the sole judgment of
         Purchaser, in any such case, and regardless of the circumstances
         (including any action or inaction by Parent or any of its affiliates)
         giving rise to any such condition, makes it inadvisable to proceed with
         such acceptance for payment or payment.

         The foregoing conditions are for the sole benefit of Purchaser and
Parent and may be asserted by Purchaser or Parent regardless of the
circumstances giving rise to any such condition or may be waived by Purchaser or
Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right; the waiver
of any such right with respect to particular facts and other circumstances shall
not be deemed a waiver with respect to any other facts and circumstances; and
each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.

         has been acquired by any person, other than Parent or any of its

                       (ii)  there shall have occurred, since the date of the
         Agreement, a change in the business, operations, financial condition,
         assets or liabilities of the Company or any Subsidiary

         with the effect that such failure of any such representation or
         warranty to be true and correct or such change, when taken together
         with all other such failures of such representations and warranties to
         be true and correct (both favorable and adverse) and all other such
         changes (both favorable and adverse), in the aggregate would have, a
         Material Adverse Effect; provided, however that, for the purpose of the
         foregoing condition, in determining whether any such representation or
         warranty is true or correct, any qualification as to materiality or
         Material Adverse Effect contained in any such representation and
         warranty shall be deemed not to apply;

                  (g) the Company shall have failed to perform in any material
         respect any material obligation or to comply in any material respect
         with any material agreement or material covenant of the Company to be
         performed or complied with by it under the Agreement;

                  (h) the Agreement shall have been terminated in accordance 
         with its terms; or

         shall terminate the Note Tender Offer or postpone the acceptance for
         payment of or payment for Notes and related Consents thereunder; which,
         in the sole judgment of Purchaser, in any such case, and regardless of
         the circumstances (including any action or inaction by Parent or any of
         its affiliates) giving rise to any such condition, makes it inadvisable
         to proceed with such acceptance for payment or payment.

         The foregoing conditions are for the sole benefit of Purchaser and
Parent and may be asserted by Purchaser or Parent regardless of the
circumstances giving rise to any such condition or may be waived by Purchaser or
Parent in whole or in part at any time and from time to time in their sole
discretion. The failure by Parent or Purchaser at any time to exercise any of
the foregoing rights shall not be deemed a waiver of any such right; the waiver
of any such right with respect to particular facts and other circumstances shall
not be deemed a waiver with respect to any other facts and circumstances; and
each such right shall be deemed an ongoing right that may be asserted at any
time and from time to time.

For a period of one year from the Effective Time, Parent shall, or shall cause

the date hereof, or such other plans, arrangements or programs as will provide
employees with benefits that in the aggregate are substantially equivalent to,
and no less favorable than, those provided under the Plans (other than the Stock
Option Plans) as in effect on the date hereof. In addition, Parent shall, or
shall cause the Surviving Corporation to, assume and agree to perform those
Change of Control Agreements listed in Schedule 6.06 of the Disclosure Schedule
in the same manner and to the same extent that the Company is required to
perform such agreements.

Richard A. Bearse
Senior Vice President, Planning and Development
United Dominion Industries
2300 One First Union Center
301 South College Street
Charlotte, NC 28202-6039
 
Dear Mr. Bearse:
 
     You have requested information regarding lmo Industries Inc. (the
"Company", "us" or "we") in connection with your consideration of a possible
negotiated transaction with the Company (a "Possible Transaction"). In
consideration of our furnishing you with the Evaluation Materials (as defined
below) you agree as follows:
 
CONFIDENTIALITY OF EVALUATION MATERIALS
 
     You and your representatives (as defined herein) will treat confidentially
any information (whether written or oral) that either we or our financial
advisor, Credit Suisse First Boston Corporation ("CSFB"), or our other
representatives furnish to you in connection with a Possible Transaction
involving the Company, together with analyses, compilations, studies or other
documents prepared by you, or by your representatives which contain or otherwise
reflect such information or your review of, or interest in, the Company
(collectively, the "Evaluation Materials"). You recognize and acknowledge the
competitive value of the Evaluation Materials and the damage that could result
to the Company if the Evaluation Materials were used or disclosed except as
authorized by this Agreement.
 
     The term "Evaluation Materials" includes information furnished to you
orally or in writing (whatever the form or storage medium) or gathered by
inspection, and regardless of whether such information is specifically
identified as "confidential". The term "Evaluation Materials" does not include
information which (i) is or becomes generally available to the public other than
as a result of a disclosure by you or your representatives, (ii) was or becomes
available to you or your representatives on a non-confidential basis from a
source other than the Company or its representatives, provided that such source
is not to your knowledge prohibited from disclosing such information to you by a
contractual, legal or fiduciary obligation to the Company or its
representatives, or (iii) is independently developed by you.
 
USE OF EVALUATION MATERIALS
 
     You and your representatives will not use any of the Evaluation Materials
for any purpose other than the exclusive purpose of evaluating a Possible
Transaction. You and your representatives will keep the Evaluation Materials
completely confidential and will not disclose the Evaluation Materials, in any
manner, in whole or in part; provided, however, that (i) any of such information
may only be disclosed to those of your directors, officers, employees, agents,
representatives (including attorneys, accountants and financial advisors),
lenders and other sources of financing (collectively, "your representatives")
who need to know such information for the purpose of evaluating a Possible
Transaction between you and the Company (it being understood that your
representatives shall be informed by you of the confidential nature of such
information and shall be directed by you and shall agree to treat such
information confidentially in accordance with this Agreement) and (ii) any other
disclosure of such information may only be made if the Company consents in
writing prior to any such disclosure. Without limiting the generality of the
foregoing, in the event that a Possible Transaction is not consummated neither
you nor your representatives shall use any of the Evaluation Materials for any
purpose. You will be responsible for any breach of this Agreement by your
representatives.
 
     In the event that you or any of your representatives receive a request or
are required (by deposition, interrogatory, request for documents, subpoena,
civil investigative demand or similar process) to
<PAGE>   2
 
disclose all or any part of the Evaluation Materials, you or your
representatives, as the case may be, agree to (i) immediately notify the Company
of the existence, terms and circumstances surrounding such a request, (ii)
consult with the Company on the advisability of taking legally available steps
to resist or narrow such request and (iii) assist the Company (at the Company's
expense) in seeking a protective order or other appropriate remedy. In the event
that such protective order or other remedy is not obtained or that the Company
waives compliance with the provisions hereof, (i) you or your representatives,
as the case may be, may disclose to any tribunal only that portion of the
Evaluation Materials which you are advised by counsel is legally required to be
disclosed, and shall exercise your best efforts to obtain assurance that
confidential treatment will be accorded such Evaluation Materials and (ii) you
shall not be liable for such disclosure unless disclosure to any such tribunal
was caused by or resulted from a previous disclosure by you or your
representatives not permitted by this Agreement.
 
NON-DISCLOSURE
 
     The disclosure of your possible interest in negotiating a transaction with
the Company could have a material adverse effect on the Company's business if
for any reason an agreement is not consummated. Accordingly, unless required by
applicable law, you agree that prior to the closing of a Possible Transaction,
without the prior written consent of the Company, you will not, and you will
direct your representatives not to, disclose to any person either the fact that
you have entered into this Agreement, that Evaluation Materials have been made
available or that discussions or negotiations are taking place concerning a
Possible Transaction between you and the Company or any of the terms, conditions
or other facts with respect to any such Possible Transaction, including the
status thereof. The term "person" as used in this letter shall be broadly
interpreted to include, without limitation, any corporation, the Company,
governmental agency or body, stock exchange, partnership, association or
individual.
 
RETURN OF DOCUMENTS
 
     Upon the Company's request, you shall promptly deliver to the Company or
destroy all written Evaluation Materials and any other written materials without
retaining, in whole or in part, any copies, extracts or other reproductions
(whatever the form or storage medium) of such materials, and shall certify the
destruction of such materials in writing to the Company. Notwithstanding the
return or destruction of the Evaluation Materials, you and your representatives
will continue to be bound by your obligations pursuant to this Agreement.
 
NO UNAUTHORIZED CONTACT OR SOLICITATION
 
     During the course of your evaluation, you agree that all inquiries and
other communications are to be made directly to CSFB or employees or
representatives of the Company specified by CSFB.
 
     Without the Company's prior written consent, the persons who are involved
in the possible transaction will not for a period of two years from the date of
this Agreement directly or indirectly solicit for employment any person who is
now employed by the Company (or whose activities are dedicated to the Company)
in an executive or management level position or otherwise considered by the
Company to be a key employee.
 
STANDSTILL
 
     You agree that until one year from the date of this Agreement, you will not
without the prior approval of the Board of Directors of the Company (i) acquire
or make any proposal to acquire any securities or property of the Company, (ii)
propose to enter into any merger or business combination involving the Company
or purchase a material portion of the assets of the Company, (iii) make or
participate in any solicitation of proxies to vote, or seek to advise or
influence any person with respect to the voting of any securities of the
Company, (iv) form, join or participate in a "group" (within the meaning of
Section 13(d)(3) of the Securities Exchange Act of 1934) with respect to any
voting securities of the Company, (v) otherwise act or seek to control or
influence the management, Board of Directors or
 
                                        2
<PAGE>   3
 
policies of the Company, (vi) disclose any intention, plan or arrangement
inconsistent with the foregoing or (vii) take any action which might require the
Company to make a public announcement regarding the possibility of a business
combination or merger. Except as provided above, you also agree during such
period not to request the Company (or its directors, officers, employees, agents
or representatives) to amend or waive any provision of this paragraph.
 
NO REPRESENTATION OR WARRANTY
 
     Although the Company and CSFB have endeavored to include in the Evaluation
Materials information known to them which they believe to be relevant for the
purpose of your investigation, you acknowledge and agree that none of the
Company, CSFB or any of the Company's other representatives or agents is making
any representation or warranty, expressed or implied, as to the accuracy or
completeness of the Evaluation Materials, and none of the Company, CSFB or any
of the Company's other representatives or agents, nor any of their respective
officers, directors, employees, representatives, stockholders, owners,
affiliates, advisors or agents, will have any liability to you or any other
person resulting from the use of Evaluation Materials by you or any of your
representatives, except as may be set forth in a definitive sale agreement. Only
those representations or warranties that are made in a definitive agreement
relating to the Company ("Sale Agreement") when, as, and if it is executed, and
subject to such limitations and restrictions as may be specified in such Sale
Agreement, will have any legal effect.
 
     You also acknowledge and agree that no contract or agreement providing for
a Possible Transaction shall be deemed to exist between you and the Company
unless and until a Sale Agreement has been executed and delivered by you and
each of the other parties thereto. You also agree that unless and until a Sale
Agreement between the Company and you with respect to a Possible Transaction has
been executed and delivered by you and each of the other parties thereto, there
shall not be any legal obligation of any kind whatsoever with respect to any
such transaction by virtue of this agreement or any other written or oral
expression with respect to such transaction except, in the case of this
Agreement, for the matters specifically agreed to herein. For purposes of this
Agreement, the term "Sale Agreement" does not include an executed letter of
intent or any other preliminary written agreement, nor does it include any oral
acceptance of an offer or bid by you.
 
     You further understand and agree that (i) the Company and CSFB shall be
free to conduct the process regarding a transaction involving the Company as
they in their sole discretion shall determine (including, without limitation,
negotiating with any other interested parties and entering into a Sale Agreement
without prior notice to you or to any other person), (ii) any procedures
relating to such sale may be changed at any time without notice to you or any
other person and (iii) you shall not have any claims whatsoever against the
Company, CSFB or any of their respective directors, officers, employees,
stockholders, owners, affiliates, agents or representatives arising out of or
relating to a transaction involving the Company (other than those as against the
parties to a Sale Agreement with you in accordance with the terms thereof).
 
LEGAL REMEDY
 
     You understand and agree that the Company would be irreparably injured and
that money damages would not be a sufficient remedy for any breach of this
Agreement by you or your representatives and that the Company will be entitled
to seek specific performance and injunctive relief as remedies for any such
breach. Such remedies shall not be deemed to be the exclusive remedies for a
breach of this Agreement by you or your representatives but shall be in addition
to all other remedies available at law or equity.
 
OTHER
 
     This Agreement constitutes the entire agreement between the parties hereto
regarding the subject matter hereof. This Agreement may be changed only by a
written agreement signed by the parties hereto or their authorized
representatives.

exclusive jurisdiction of the courts of the United States of America located in

relating to this Agreement and the transactions contemplated hereby (and you
agree not to commence any action, suit or proceeding relating thereto except in
such courts), and further agree that service of any process, summons, notice or
document by U.S. registered mail to your address set forth above shall be

such court that any such action, suit or proceeding brought in any such court

exercising any right, power or privilege under this Agreement shall operate as a
waiver thereof nor shall any single or partial exercise thereof preclude any
other or further exercise of any right, power or privilege hereunder.

of the State of New York, without regard to the conflicts of law principles
thereof.

Board of Directors
Imo Industries Inc.
1009 Lenox Drive
Lawrenceville, New Jersey 08648

Attention:  Donald K. Farrar
            Chairman of the Board

Dear Mr. Farrar:

     This letter expresses the intention of United Dominion Industries Limited
or its designee (the "Purchaser") and Imo Industries Inc. (the "Company") with
respect to proceeding with negotiations towards the potential acquisition of
the company (the "Proposed Transaction") by the Purchaser:

     1.     Purchaser and the Company agree that Purchaser will be provided
access to the Company's financial, legal, tax, human resources, environmental,
health and safety, and other records, its personnel, its operations and its
facilities for the conduct of a due diligence review from the date hereof
through and until June 30, 1997 (the "Due Diligence Period").

     2.     During the Due Diligence Period, the Purchaser and the Company
agree to work diligently in good faith towards the preparation and execution of
a definitive Agreement and Plan of Merger (the "Merger Agreement") covering,
among other things, the terms of the Proposed Transaction and containing
representations and warranties, covenants, indemnities, provision for a
break-up fee, a fiduciary out and conditions typical of a transaction of this
type. The execution and delivery of the Merger Agreement by the Purchaser shall
be subject to the Purchaser's satisfactory completion of its due diligence
review.

     3.     In order to cause Purchaser to be willing to spend the time and
incur the expense necessary to conduct due diligence and negotiate a Merger
Agreement, the Company agrees that it will not, and no director, officer,
stockholder, employee, agent or other representative of the company shall be
authorized by the Company to, negotiate or solicit proposals for the sale or
other disposition of the Company or its assets (whether by means of a negotiated
sale of securities or assets, tender or exchange offer, merger or other
business combination, recapitalization, restructuring or other transaction (any
such transaction being referred to herein as a "Sale")) with or from any other
party during the Due Diligence Period; provided, however that this obligation
shall terminate at 5:00 p.m., New York time on June 25, 1997, if the Purchaser
has not notified the Company by that time that its board of directors has
determined to proceed with the transaction. In addition, the Company agrees
that it will immediately cease and cause to be terminated during such period any
existing activities, discussions or negotiations with any person other than the
Purchaser or its affiliates in respect of a Sale. In the event the company
receives an unsolicited offer (an "Other Offer") during the Due Diligence
Period and is advised in writing by its legal counsel that its board of
directors has a fiduciary obligation to consider and respond to such Other
Offer prior to the expiration of the Due Diligence Period, it may do so
provided it advises Purchaser of the receipt of such Other Offer and allows
Purchaser to submit a competing offer for consideration by the Company's board
at the same meeting at which such Other Offer is to be considered. In
consideration of the Company's agreement hereto, Purchaser agrees to diligently
pursue its review during the Due Diligence Period and agrees further to notify
the Company within twenty-four (24) hours of any determination to not proceed
with a transaction as contemplated by the parties, whereupon the provisions of
this paragraph will terminate.

     4.     The parties hereto agree, until entry into the Merger Agreement, to
keep confidential, and to cause their respective affiliates and representatives
to keep confidential, all discussions, communications and evaluation materials
relating to the

Proposed Transaction, including (i) the existence of this letter, (ii) the fact
that negotiations are taking place concerning the Proposed Transaction and
(iii) the terms, conditions and other facts with respect to the Proposed
Transaction, except and only to the extent that, in the opinion of counsel,
disclosure is advisable in connection with or pursuant to any governmental or
court proceeding, law or regulation. The Purchaser further agrees that the
terms of this paragraph 4 are in addition to the Purchaser's obligations under
that certain Confidentiality Agreement, dated as of April 25, 1997, between the
Purchaser and the Company.

     5.     It is the intention of the Company to call and hold a meeting of
its board of directors to consider a transaction with Purchaser prior to the
end of the Due Diligence Period. In the event it is not able to do so, the
provisions of paragraph 3 above shall be automatically extended until such time
as such a meeting is held unless the Purchaser has advised the Company that it
no longer is pursuing a transaction with the Company.

     If the foregoing correctly sets forth our agreement with respect to the
matters set forth herein, please so indicate by executing in the appropriate
space provided below.
