TO THE HOLDERS OF COMMON STOCK OF PRIME SERVICE, INC.:
 
                                  INTRODUCTION
 
    PS Acquisition Corp., a Delaware corporation (the "Offeror") and a wholly
owned subsidiary of Atlas Copco North America Inc., a Delaware corporation
("Parent"), hereby offers to purchase all outstanding shares of Common Stock,
$.01 par value per share, of Prime Service, Inc., a Delaware corporation (the
"Company"), (collectively, the "Shares"), at a purchase price of $32.00 per
Share, net to the seller in cash, without interest, upon the terms and subject
to the conditions set forth in this Offer to Purchase and in the related Letter
of Transmittal (which, together with any amendments or supplements hereto or
thereto, collectively constitute the "Offer"). Tendering holders of Shares will
not be obligated to pay brokerage fees or commissions or, except as set forth in
the Letter of Transmittal, stock transfer taxes on the purchase of Shares by the
Offeror pursuant to the Offer. The Offeror will pay all charges and expenses of
Merrill Lynch, Pierce, Fenner & Smith Incorporated (the "Dealer Manager" or
"Merrill Lynch"), The Bank of New York (the "Depositary") and Georgeson &
Company Inc. (the "Information Agent") in connection with the Offer.
 
    THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE OFFER,
THE MERGER (AS DEFINED HEREIN) AND THE MERGER AGREEMENT (AS DEFINED HEREIN), HAS
DETERMINED THAT THE OFFER AND THE MERGER ARE FAIR TO, AND IN THE BEST INTERESTS
OF, THE COMPANY AND THE COMPANY'S STOCKHOLDERS AND RECOMMENDS THAT HOLDERS OF
THE SHARES ACCEPT THE OFFER AND TENDER THEIR SHARES PURSUANT TO THE OFFER.
 
    The Company has advised the Offeror that Credit Suisse First Boston
Corporation ("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 the
Merger Agreement, the consideration to be offered to the Company's stockholders
pursuant to the Offer and the Merger is fair to such stockholders from a
financial point of view. A copy of such opinion is set forth in full in the
Company's Solicitation/Recommendation Statement on Schedule 14D-9 which is being
mailed to the Company's stockholders with this Offer to Purchase, and such
stockholders are urged to read the opinion in its entirety.
 
    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TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST TWENTY
MILLION (20,000,000) SHARES (THE "MINIMUM CONDITION"), (II) ANY WAITING PERIOD
UNDER THE HART-SCOTT-RODINO ANTITRUST IMPROVEMENTS ACT OF 1976, AS AMENDED (THE
"HSR ACT"), APPLICABLE TO THE PURCHASE OF SHARES PURSUANT TO THE OFFER HAVING
EXPIRED OR HAVING BEEN TERMINATED PRIOR TO THE EXPIRATION OF THE OFFER AND (III)
THE SATISFACTION OF CERTAIN OTHER TERMS AND CONDITIONS. SEE SECTION 15.
 
    The Offer is being made pursuant to the Agreement and Plan of Merger, dated
as of June 8, 1997 (the "Merger Agreement"), among Parent, the Offeror and the
Company. The Merger Agreement provides that, among other things, 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 the relevant
provisions of the General Corporation Law of the State of Delaware, as amended
(the "DGCL"), the Offeror will be merged with and into the Company (the
"Merger"). If the Offeror acquires at least 90% of the outstanding Shares
pursuant to the Offer, the Offeror would be able to effect the Merger pursuant
to the "short form" merger provisions of Section 253 of the DGCL, without prior
notice to, or any action by, any stockholder of the Company. See Section 12.
Following consummation of the Merger, the Company will continue as the surviving
corporation (the "Surviving Corporation") and will be a wholly owned subsidiary
of Parent. At the effective time of the Merger (the "Effective Time"), each
Share that is issued and outstanding (other than Shares owned by the Company,
any subsidiary of the Company, Parent, the Offeror, any other subsidiary of
Parent or by stockholders, if any, who are entitled to and who properly exercise
appraisal rights under the DGCL) will be canceled and become the right to
receive from the Surviving Corporation $32.00 (or any higher price that may be
paid for each Share pursuant to the Offer) in cash, without interest thereon
(the "Offer Price"). See Section 5 for a description of certain tax consequences
of the Offer and the Merger.
<PAGE>
    The Merger Agreement provides that, promptly after the acquisition by the
Offeror of such number of Shares constituting a majority of the outstanding
Shares pursuant to the Offer, Parent will be entitled, to the fullest extent
permitted by law, to designate at its option a majority of the members of the
Board of Directors of the Company. The Company has agreed, at the option of
Parent, either to increase the size of the Board of Directors of the Company
and/or obtain the resignation of such number of directors as is necessary to
enable Parent's designees to be elected or appointed to the Board, and to take
all action necessary to effect any such election. The Merger Agreement is more
fully described in Section 13.
 
    In connection with the execution and delivery of the Merger Agreement,
Parent and certain affiliates and clients of Investcorp S.A., a Luxembourg
corporation (collectively, the "International Investors"), have entered into the
Stockholder Agreement, dated as of June 8, 1997 (the "Stockholder Agreement"),
pursuant to which the International Investors have agreed, among other things,
to tender their respective Shares (collectively, the "International Investor
Shares") to the Offeror in connection with the Offer, constituting an aggregate
of approximately 74.0% of the outstanding Shares. Subject to the terms and
conditions of the Stockholder Agreement, the International Investors have agreed
to vote, and have appointed Parent and its officers, Mr. Mark Cohen and Mr.
Sixten Nordmark, as their irrevocable proxies to vote, the International
Investor Shares in favor of the Merger and of certain related actions and
against certain other enumerated actions or agreements. Subject to the terms and
conditions of the Stockholder Agreement, the International Investors have agreed
to refrain from soliciting or responding to certain inquiries or proposals
regarding the Company, to comply with certain restrictions upon the transfer of
the International Investor Shares, to waive any rights of appraisal available in
the Merger and to take or refrain from taking certain other actions.
 
    The Stockholder Agreement also provides that, under certain circumstances,
if any of the International Investors receives any consideration in excess of
$32.00 in respect of all or any portion of the International Investor Shares
from Parent, the Offeror or any of their affiliates or, following a termination
of the Merger Agreement, from a third party in connection with a Third Party
Business Combination (as defined below), Parent will be entitled to all or a
portion of such consideration, to the extent in excess of $32.00 and less than
or equal to $36.00. The Stockholder Agreement is more fully described in Section
13.
 
    The Company has advised the Offeror that as of June 6, 1997, there were
27,991,721 Shares issued and outstanding, and as of the date of the Merger
Agreement there were outstanding stock options and rights to purchase not in
excess of 611,732 Shares. As of the date hereof, (i) neither the Offeror nor
Parent beneficially owns any Shares and (ii) the International Investors
beneficially own in the aggregate 20,722,116 Shares, constituting approximately
74.0% of the outstanding Shares. If the Offeror acquires at least 14,301,727
Shares in the Offer, it will control a majority of the outstanding Shares
(assuming the exercise of all options to purchase Shares outstanding at the
expiration date of the Offer). Accordingly, the Offeror would have sufficient
voting power to approve the Merger without the affirmative vote of any other
stockholder of the Company.
 
    THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION WHICH SHOULD BE READ BEFORE ANY DECISION IS MADE WITH
RESPECT TO THE OFFER.
 
1. TERMS OF THE OFFER.
 
    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any extension or
amendment), the Offeror will accept for payment and pay for all Shares validly
tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 4. The term "Expiration Date" means 12:00 Midnight, New
York City time, on Monday, July 7, 1997, unless the Offeror shall have extended
the period of time for which the Offer is open, in which event the term
"Expiration Date" shall mean the latest time and date at which the Offer, as so
extended by the Offeror, shall expire.
 
                                       2
<PAGE>
    If the Offeror shall decide, in its sole discretion, to increase the
consideration offered in the Offer to holders of Shares and if, at the time that
notice of such increase is first published, sent or given to holders of Shares
in the manner specified below, the Offer is scheduled to expire at any time
earlier than the expiration of a period ending on the tenth business day from,
and including, the date that such notice is first so published, sent or given,
then the Offer will be extended until the expiration of such period of 10
business days. For purposes of the Offer, a "business day" means any day other
than a Saturday, Sunday or a federal holiday and consists of the time period
from 12:01 a.m. through 12:00 Midnight, New York City time.
 
    THE OFFER IS CONDITIONED UPON THERE BEING VALIDLY TENDERED AND NOT WITHDRAWN
PRIOR TO THE EXPIRATION OF THE OFFER AT LEAST TWENTY MILLION (20,000,000)
SHARES, ANY WAITING PERIOD UNDER THE HSR ACT APPLICABLE TO THE PURCHASE OF
SHARES PURSUANT TO THE OFFER HAVING EXPIRED OR HAVING BEEN TERMINATED PRIOR TO
THE EXPIRATION OF THE OFFER AND CERTAIN OTHER TERMS AND CONDITIONS. SEE SECTION
15. THE MERGER AGREEMENT AND THE OFFER MAY BE TERMINATED BY THE OFFEROR AND
PARENT IF CERTAIN EVENTS OCCUR. The Offeror reserves the right (but shall not be
obligated), in accordance with applicable rules and regulations of the United
States Securities and Exchange Commission (the "Commission"), subject to the
limitations set forth in the Merger Agreement and described below, to waive any
condition to the Offer. If the Minimum Condition or any condition set forth in
Section 15 has not been satisfied by 12:00 Midnight, New York City time, on
Monday, July 7, 1997 (or any other time then set as the Expiration Date), the
Offeror may, subject to the terms of the Merger Agreement as described below,
elect to (1) extend the Offer and, subject to applicable withdrawal rights,
retain all tendered Shares until the expiration of the Offer, as extended, (2)
subject to complying with applicable rules and regulations of the Commission,
accept for payment all Shares so tendered and not extend the Offer or (3)
terminate the Offer and not accept for payment any Shares and return all
tendered Shares to tendering stockholders.
 
    Under the terms of the Merger Agreement, the Offeror may not (except as
described in the next sentence), without the consent of the Company, decrease
the Offer Price, change the form of consideration to be paid pursuant to the
Offer, decrease the number of Shares being sought pursuant to the Offer, amend
or modify any of the conditions to the Offer, impose any additional conditions
to the Offer, extend the Offer, if all of the Offer conditions have been
satisfied or waived, or amend any other term or condition of the Offer.
Notwithstanding the foregoing, the Offeror may, in its sole discretion and
without the consent of the Company, extend the Offer at any time and from time
to time (i) if at the Expiration Date of the Offer, any of the conditions shall
not have been satisfied, (ii) for any period required by applicable law,
including, without limitation, any rule, regulation, interpretation or position
of the Commission or the Commission staff applicable to the Offer, or (iii) if
on the Expiration Date of the Offer all of the conditions to the Offer shall
have been satisfied or waived but the number of Shares that have been validly
transferred and not withdrawn is less than 90% of the then outstanding Shares,
for an aggregate period of not more than five business days beyond the latest
expiration date permitted under clause (i) or (ii) of this sentence provided
that, in the event of any such extension, all of the conditions to the Offer and
to Parent's and the Offeror's obligations to consummate the Merger that have
been satisfied as of such date shall be deemed irrevocably waived by Parent and
the Offeror.
 
    Subject to the limitations set forth in this Offer and the Merger Agreement,
the Offeror reserves the right (but will not be obligated), at any time or from
time to time in its sole discretion, to extend the period during which the Offer
is open by giving oral or written notice of such extension to the Depositary and
by making a public announcement of such extension. Except to the extent required
by the Merger Agreement, there can be no assurance that the Offeror will
exercise its right to extend the Offer. See Section 13.
 
    Subject to the applicable rules and regulations of the Commission and
subject to the limitations set forth in the Merger Agreement, the Offeror
expressly reserves the right, at any time and from time to time, in its sole
discretion, (i) to delay payment for any Shares regardless of whether such
Shares were theretofore accepted for payment, or to terminate the Offer and not
to accept for payment or pay for any Shares not theretofore accepted for payment
or paid for, upon the occurrence of any of the conditions set
 
                                       3
<PAGE>
forth in Section 15, by giving oral or written notice of such delay or
termination to the Depositary, and (ii) at any time or from time to time, to
amend the Offer in any respect (subject to the provisions of the Merger
Agreement). The Offeror's right to delay payment for any Shares or not to pay
for any Shares theretofore accepted for payment is subject to the applicable
rules and regulations of the Commission, including Rule 14e-1(c) under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), relating to
the Offeror's obligation to pay for or return tendered Shares promptly after the
termination or withdrawal of the Offer.
 
    Any extension of the period during which the Offer is open, delay in
acceptance for payment or payment, termination or amendment of the Offer will be
followed, as promptly as practicable, by public announcement thereof, such
announcement in the case of an extension to be issued not later than 9:00 a.m.,
New York City time, on the next business day after the previously scheduled
Expiration Date in accordance with the public announcement requirements of Rules
14d-4(c) and 14e-1(d) under the Exchange Act. Without limiting the obligation of
the Offeror under such rule or the manner in which the Offeror may choose to
make any public announcement, the Offeror currently intends to make
announcements by issuing a press release to the Dow Jones News Service and
making any appropriate filing with the Commission.
 
    If, subject to the terms of the Merger Agreement, the Offeror makes a
material change in the terms of the Offer or the information concerning the
Offer, or if it waives a material condition of the Offer, the Offeror will
disseminate additional tender offer materials and extend the Offer if and to the
extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under the Exchange Act or
otherwise. The minimum period during which a tender offer must remain open
following material changes in the terms of the Offer or the information
concerning the Offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances, including the
relative materiality of the terms or information changes. With respect to a
change in price or a change in percentage of securities sought, a minimum 10
business day period is generally required to allow for adequate dissemination to
stockholders and investor response.
 
    The Company has provided the Offeror with the Company's list of stockholders
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
will be mailed to record holders of Shares whose names appear on the Company's
stockholder list and will be furnished 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 for subsequent transmittal to
beneficial owners of Shares.
 
2. ACCEPTANCE FOR PAYMENT AND PAYMENT FOR SHARES.
 
    Upon the terms and subject to the conditions of the Offer (including, if the
Offer is extended or amended, the terms and conditions of any such extension or
amendment), the Offeror will accept for payment and will pay for all Shares
validly tendered prior to the Expiration Date and not theretofore withdrawn in
accordance with Section 4 promptly after the later to occur of (a) the
Expiration Date and (b) the satisfaction or waiver of the conditions set forth
in Section 15 related to regulatory matters. Subject to compliance with Rule
14e-1(c) under the Exchange Act and any other applicable rules of the
Commission, the Offeror expressly reserves the right to delay acceptance for
payment and payment for Shares in order to comply in whole or in part with any
applicable law. See Sections 1 and 16. 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) certificates for such Shares 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 (collectively, the "Book Entry Transfer
Facilities"), pursuant to the procedures set forth in Section 3, (ii) a properly
completed and duly executed Letter of Transmittal (or a manually signed
facsimile thereof) with all required signature guarantees or, in
 
                                       4
<PAGE>
the case of a book entry transfer, an Agent's Message (as defined below) and
(iii) any other documents required by the Letter of Transmittal.
 
    The term "Agent's Message" means a message transmitted by 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
Offeror may enforce such agreement against the participant.
 
    For purposes of the Offer, the Offeror will be deemed to have accepted for
payment, and thereby purchased, Shares validly tendered and not withdrawn as, if
and when the Offeror gives oral or written notice to the Depositary of the
Offeror's acceptance of such Shares for payment pursuant to the Offer. In all
cases, payment for Shares purchased pursuant to the Offer will be made by
deposit of the purchase price with the Depositary, which will act as agent for
tendering stockholders for the purpose of receiving payment from the Offeror and
transmitting such payment to tendering stockholders. If, for any reason
whatsoever, acceptance for payment of any Shares tendered pursuant to the Offer
is delayed, or the Offeror is unable to accept for payment Shares tendered
pursuant to the Offer, then, without prejudice to the Offeror's rights under
Section 1, the Depositary may, nevertheless, on behalf of the Offeror, retain
tendered Shares, and such Shares may not be withdrawn, except to the extent that
the tendering stockholders are entitled to withdrawal rights as described in
Section 4 below and as otherwise required by Rule 14e-1(c) under the Exchange
Act. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID BY THE OFFEROR BECAUSE OF ANY
DELAY IN MAKING ANY PAYMENT.
 
    If any tendered Shares are not accepted for payment pursuant to the terms
and conditions of the Offer for any reason, or if certificates are submitted for
more Shares than are tendered, certificates for such unpurchased or untendered
Shares will be returned, without expense to the tendering stockholder (or, in
the case of Shares delivered by book entry transfer to a Book Entry Transfer
Facility, such Shares will be credited to an account maintained within such Book
Entry Transfer Facility), as promptly as practicable after the expiration,
termination or withdrawal of the Offer.
 
    If, prior to the Expiration Date, the Offeror increases the price being paid
for Shares accepted for payment pursuant to the Offer, such increased
consideration will be paid to all stockholders whose Shares are purchased
pursuant to the Offer, whether or not such Shares were tendered prior to such
increase in consideration.
 
3. PROCEDURE FOR TENDERING SHARES.
 
    VALID TENDERS.  For Shares to be validly tendered pursuant to the Offer,
either a properly completed and duly executed Letter of Transmittal (or a
manually signed facsimile thereof), with any required signature guarantees, or,
in the case of a book entry transfer, an Agent's Message, and any other required
documents, must 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 set
forth below. In addition, either (i) certificates representing such Shares must
be received by the Depositary along with the Letter of Transmittal or such
Shares must be tendered pursuant to the procedure for book entry transfer set
forth below, and a Book Entry Confirmation must be received by the Depositary,
in each case prior to the Expiration Date, or (ii) the guaranteed delivery
procedures set forth below must be complied with. No alternative, conditional or
contingent tenders will be accepted. DELIVERY OF DOCUMENTS TO A BOOK ENTRY
TRANSFER FACILITY IN ACCORDANCE WITH SUCH BOOK ENTRY TRANSFER FACILITY'S
PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
    BOOK ENTRY TRANSFER.  The Depositary will make a request to establish an
account with respect to the Shares at each Book Entry Transfer Facility 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 a Book Entry
Transfer
 
                                       5
<PAGE>
Facility's system may make book entry delivery of Shares by causing a Book Entry
Transfer Facility to transfer such Shares into the Depositary's account at a
Book Entry Transfer Facility in accordance with such Book Entry Transfer
Facility's procedures for transfer. Although delivery of Shares may be effected
through book entry at a Book Entry Transfer Facility prior to the Expiration
Date, (i) the Letter of Transmittal (or a manually signed facsimile thereof),
properly completed and duly executed, 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 transmitted to and received by the
Depositary at one of its addresses set forth on the back cover of this Offer to
Purchase or (ii) the guaranteed delivery procedures described below must be
complied with.
 
    SIGNATURE GUARANTEE.  Signatures on the Letter of Transmittal must be
guaranteed by a member in good standing of the Securities Transfer Agents
Medallion Program, the New York Stock Exchange Medallion Signature Guarantee
Program, the Stock Exchange Medallion Program, or by any other bank, broker,
dealer, credit union, savings association or other entity which is an "eligible
guarantor institution," as such term is defined in Rule 17Ad-15 under the
Exchange Act (each of the foregoing being referred to as an "Eligible
Institution" and, collectively, as "Eligible Institutions"), unless the Shares
tendered thereby are tendered (i) by a registered holder of Shares who has not
completed either the box labeled "Special Delivery Instructions" or the box
labeled "Special Payment Instructions" on the Letter of Transmittal or (ii) for
the account of any Eligible Institution. If the certificates evidencing Shares
are registered in the name of a person or persons other than the signer of the
Letter of Transmittal, or if payment is to be made, or delivered to, or
certificates for unpurchased Shares are to be issued or returned to, a person
other than the registered owner or owners, then the tendered certificates must
be endorsed or accompanied by duly executed stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates, with the signatures on the certificates or stock powers guaranteed
by an Eligible Institution as provided in the Letter of Transmittal. See
Instructions 1 and 5 to the Letter of Transmittal.
 
    GUARANTEED DELIVERY.  If a stockholder desires to tender Shares pursuant to
the Offer and such stockholder's certificates for Shares are not immediately
available or time will not permit all required documents to reach the Depositary
prior to the Expiration Date or the procedure for book entry transfer cannot be
completed on a timely basis, such Shares may nevertheless be tendered if all of
the following guaranteed delivery procedures are duly complied with:
 
        (i) the tender is made by or through an Eligible Institution;
 
        (ii) a properly completed and duly executed Notice of Guaranteed
    Delivery, substantially in the form made available by the Offeror, is
    received by the Depositary, as provided below, prior to the Expiration Date;
    and
 
       (iii) the certificates for all tendered Shares, in proper form for
    transfer (or a Book Entry Confirmation), together with a properly completed
    and duly executed Letter of Transmittal (or a manually signed facsimile
    thereof), and 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 after the date of such Notice of Guaranteed Delivery. The term "trading
    day" is any day on which the New York Stock Exchange ("NYSE") is open for
    business.
 
    The Notice of Guaranteed Delivery may be delivered by hand or transmitted by
facsimile transmission or mail to the Depositary and must include a guarantee by
an Eligible Institution in the form set forth in the Notice of Guaranteed
Delivery.
 
    THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH ANY BOOK ENTRY TRANSFER FACILITY,
IS AT THE OPTION AND RISK OF THE TENDERING STOCKHOLDER. SHARES WILL BE DEEMED
DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE DEPOSITARY (INCLUDING, IN
 
                                       6
<PAGE>
THE CASE OF A BOOK ENTRY TRANSFER, BY BOOK ENTRY CONFIRMATION). 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.
 
    Notwithstanding any other provision hereof, payment for Shares accepted for
payment pursuant to the Offer will in all cases be made only after timely
receipt by the Depositary of (i) certificates for such Shares or a Book Entry
Confirmation, (ii) a properly completed and duly executed Letter of Transmittal
(or a manually signed facsimile thereof), with all required signature guarantees
or, in the case of a book entry transfer, an Agent's Message, and (iii) any
other documents required by the Letter of Transmittal. Accordingly, tendering
stockholders may be paid at different times depending upon when certificates for
Shares or Book Entry Confirmations with respect to Shares are actually received
by the Depositary. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE
PRICE OF THE SHARES TO BE PAID BY THE OFFEROR, REGARDLESS OF ANY EXTENSION OF
THE OFFER OR ANY DELAY IN MAKING ANY PAYMENT.
 
    BACKUP FEDERAL INCOME TAX WITHHOLDING.  TO PREVENT 31% "BACKUP" FEDERAL
INCOME TAX WITHHOLDING WITH RESPECT TO PAYMENT OF THE PURCHASE PRICE OF SHARES
PURCHASED PURSUANT TO THE OFFER, EACH STOCKHOLDER MUST, SUBJECT TO CERTAIN
EXCEPTIONS, PROVIDE THE DEPOSITARY WITH SUCH STOCKHOLDER'S CORRECT TAXPAYER
IDENTIFICATION NUMBER ("TIN") AND CERTIFY THAT SUCH STOCKHOLDER IS NOT SUBJECT
TO BACKUP FEDERAL INCOME TAX WITHHOLDING BY COMPLETING THE SUBSTITUTE FORM W-9
INCLUDED IN THE LETTER OF TRANSMITTAL. FOREIGN HOLDERS MUST GENERALLY SUBMIT A
COMPLETED FORM W-8 TO AVOID 31% BACKUP WITHHOLDING. THIS FORM MAY BE OBTAINED
FROM THE DEPOSITARY. SEE INSTRUCTIONS 8 AND 9 SET FORTH IN THE LETTER OF
TRANSMITTAL.
 
    DETERMINATION OF VALIDITY.  All questions as to the form of documents and
the validity, eligibility (including time of receipt) and acceptance for payment
of any tender of Shares will be determined by the Offeror, in its sole
discretion, and its determination will be final and binding on all parties. The
Offeror reserves the absolute right to reject any or all tenders of any Shares
that are determined by it not to be in proper form or the acceptance of or
payment for which may, in the opinion of the Offeror, be unlawful. The Offeror
also reserves the absolute right to waive any of the conditions of the Offer,
subject to the limitations set forth in the Merger Agreement, or any defect or
irregularity in the tender of any Shares. The Offeror's interpretation of the
terms and conditions of the Offer (including the Letter of Transmittal and the
Instructions to the Letter of Transmittal) will be final and binding on all
parties. No tender of Shares will be deemed to have been validly made until all
defects and irregularities have been cured or waived. None of the Offeror,
Parent, the Dealer Manager, the Depositary, the Information Agent or any other
person will be under any duty to give notification of any defects or
irregularities in tenders or incur any liability for failure to give any such
notification.
 
    OTHER REQUIREMENTS.  By executing the Letter of Transmittal as set forth
above (including through delivery of an Agent's Message), a tendering
stockholder irrevocably appoints designees of the Offeror as such stockholder's
attorneys in fact and 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 right with respect to the Shares tendered by such stockholder and
accepted for payment by the Offeror (and any and all other Shares or other
securities issued or issuable in respect of such Shares). All such powers of
attorney and proxies shall be considered coupled with an interest in the
tendered Shares. This appointment is effective when, and only to the extent
that, the Offeror accepts for payment the Shares deposited with the Depositary.
Upon acceptance for payment, all prior powers of attorney and proxies given by
the stockholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent proxies may be given or
written consent executed (and, if given or executed, will not be deemed
effective). The designees of the Offeror will, with respect to the Shares and
other securities or rights, be empowered to exercise all voting and other rights
of such stockholder as they in their sole judgment deem proper in respect of any
annual or special meeting of the Company's stockholders, or any adjournment or
postponement thereof, any actions by written consent in lieu of any such meeting
or otherwise. The Offeror reserves the right to require that, in order for
Shares to be deemed validly tendered, immediately upon the
 
                                       7
<PAGE>
Offeror's payment for such Shares, the Offeror must be able to exercise full
voting and other rights with respect to such Shares and the other securities or
rights issued or issuable in respect of such Shares, including voting at any
meeting of stockholders (whether annual or special or whether or not adjourned)
in respect of such Shares.
 
    A tender of Shares pursuant to any one of the procedures described above
will constitute the tendering stockholder's acceptance of the terms and
conditions of the Offer, as well as the tendering stockholder's representation
and warranty that (i) such stockholder has the full power and authority to
tender, sell, assign and transfer the tendered Shares (and any and all other
Shares or other securities issued or issuable in respect of such Shares), and
(ii) when the same are accepted for payment by the Offeror, the Offeror will
acquire good and unencumbered title thereto, free and clear of all liens,
restrictions, charges and encumbrances and not subject to any adverse claims.
The Offeror's acceptance for payment of Shares tendered pursuant to the Offer
will constitute a binding agreement between the tendering stockholder and the
Offeror upon the terms and subject to the conditions of the Offer.
 
4. WITHDRAWAL RIGHTS.
 
    Except as otherwise provided in this Section 4, tenders of Shares made
pursuant to the Offer are irrevocable. Shares tendered pursuant to the Offer may
be withdrawn at any time prior to the Expiration Date and, unless theretofore
accepted for payment pursuant to the Offer, may also be withdrawn at any time
after August 7, 1997. If purchase of or payment for Shares is delayed for any
reason or if the Offeror is unable to purchase or pay for Shares for any reason,
then, without prejudice to the Offeror's rights under the Offer, tendered Shares
may be retained by the Depositary on behalf of the Offeror and may not be
withdrawn except to the extent that tendering stockholders are entitled to
withdrawal rights as set forth in this Section 4, subject to Rule 14e-1(c) under
the Exchange Act, which provides that no person who makes a tender offer shall
fail to pay the consideration offered or return the securities deposited by or
on behalf of security holders promptly after the termination or withdrawal of
the Offer.
 
    For a withdrawal of Shares tendered pursuant to the Offer to be effective, a
written, telegraphic, telex or facsimile transmission notice of withdrawal must
be timely received by the Depositary at one of its addresses set forth on the
back cover of this Offer to Purchase. Any 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 in which the certificates representing such Shares
are registered, if different from that of the person who tendered the Shares. If
certificates for Shares to be withdrawn have been delivered or otherwise
identified to the Depositary, then, prior to the physical release of such
certificates, the serial numbers shown on such certificates must be submitted to
the Depositary and, unless such Shares have been tendered by an Eligible
Institution, the signatures on the notice of withdrawal must be guaranteed by an
Eligible Institution. If Shares have been tendered pursuant to the procedures
for book entry transfer set forth in Section 3, any notice of withdrawal must
also specify the name and number of the account at the Book Entry Transfer
Facility to be credited with the withdrawn Shares and must otherwise comply with
such Book Entry Transfer Facility's procedures. All questions as to the form and
validity (including time of receipt) of notices of withdrawal will be determined
by the Offeror, in its sole discretion, and its determination will be final and
binding on all parties. None of the Offeror, Parent, the Dealer Manager, the
Depositary, the Information Agent or any other person will be under any duty to
give notification of any defects or irregularities in any notice of withdrawal
or incur any liability for failure to give any such notification.
 
    Any Shares properly withdrawn will be deemed not validly tendered for
purposes of the Offer, but may be re-tendered at any subsequent time prior to
the Expiration Date by following any of the procedures described in Section 3.

5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES.
 
    The following is a summary of certain United States federal income tax
consequences of the Offer and the Merger to beneficial owners of Shares whose
Shares are purchased pursuant to the Offer or whose Shares are converted into
the right to receive cash in the Merger. The discussion is for general
information only and does not purport to consider all aspects of federal income
taxation that might be relevant to beneficial owners of Shares. The discussion
is based on current provisions of the Internal Revenue Code of 1986, as amended
(the "Code"), existing, proposed and temporary regulations promulgated
thereunder and administrative and judicial interpretations thereof, all of which
are subject to change. The discussion applies only to beneficial owners of
Shares in whose hands Shares are capital assets within the meaning of Section
1221 of the Code, and may not apply to Shares received pursuant to the exercise
of employee stock options or otherwise as compensation, or to certain types of
beneficial owners of Shares (such as insurance companies, tax-exempt
organizations and broker-dealers) who may be subject to special rules. This
discussion does not discuss the federal income tax consequences to a beneficial
owner of Shares who, for United States federal income tax purposes, is a
non-resident alien individual, a foreign corporation, a foreign partnership or a
foreign estate or trust, nor does it consider the effect of any foreign, state
or local tax laws.
 
    BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH BENEFICIAL OWNER OF SHARES
SHOULD CONSULT SUCH BENEFICIAL OWNER'S OWN TAX ADVISOR TO DETERMINE THE
APPLICABILITY OF THE RULES DISCUSSED BELOW TO SUCH BENEFICIAL OWNER AND THE
PARTICULAR TAX EFFECTS TO SUCH BENEFICIAL OWNER OF THE OFFER AND THE MERGER,
INCLUDING THE APPLICATION AND EFFECT OF STATE, LOCAL AND OTHER TAX LAWS.
 
    The receipt of cash for Shares pursuant to the Offer or the Merger will be a
taxable transaction for federal income tax purposes. In general, for federal
income tax purposes, a beneficial owner of Shares will recognize gain or loss
equal to the difference between the beneficial owner's adjusted tax basis in the
Shares sold pursuant to the Offer or converted into the right to receive cash in
the Merger and the amount of cash received therefor. Gain or loss must be
determined separately for each block of Shares (i.e., Shares acquired at the
same cost in a single transaction) sold pursuant to the Offer or converted into
the right to receive cash in the Merger, although, under proposed legislation
not yet effective, gain or loss would be determined based on the average tax
basis of all Shares held by the beneficial owner. Such gain or loss will be
capital gain or loss and will be long-term capital gain or loss if the
beneficial owner held the Shares for more than one year as of the date of sale
(in the case of the Offer) or the Effective Time (in the case of the Merger).
Long-term capital gain of individuals currently is taxed at a maximum rate of
28%. Legislation has been proposed which, if enacted, would favorably affect the
taxation of capital gains. It is uncertain whether, in what form, and with what
effective date any such legislation will be enacted. However, the chairmen of
the House Ways and Means Committee and the Senate Finance Committee have stated
their present intention to propose legislation regarding capital gains effective
tax rate reductions which will be effective for transactions occurring on or
after May 7, 1997.
 
    Payments in connection with the Offer or the Merger may be subject to
"backup withholding" at a rate of 31%, unless a beneficial owner of Shares (a)
is a corporation or comes within certain exempt categories and, when required,
demonstrates this fact or (b) provides a correct TIN to the payor, certifies as
to no loss of exemption from backup withholding and otherwise complies with
applicable requirements of the backup withholding rules. A beneficial owner who
does not provide a correct TIN may be subject to penalties imposed by the
Internal Revenue Service. Any amount paid as backup withholding does not
constitute an additional tax and will be creditable against the beneficial
owner's federal income tax liability. Each beneficial owner of Shares should
consult with his or her own tax advisor as to his or her qualification for
exemption from backup withholding and the procedure for obtaining such
exemption. Those tendering their Shares in the Offer may prevent backup
withholding by completing the Substitute Form W-9 included in the Letter of
Transmittal. See Section 3. Similarly, those who convert their Shares into the
right to receive cash in the Merger may prevent backup withholding by completing
a Substitute Form W-9 and submitting it to the paying agent for the Merger.
 
                                       9
<PAGE>
    Parent and the Offeror will be entitled to deduct and withhold from the
consideration otherwise payable pursuant to the Merger Agreement to any holder
of Shares such amounts as Parent or the Offeror is required to deduct and
withhold with respect to the making of such payment. To the extent that amounts
are so withheld by Parent or the Offeror, such withheld amounts shall be treated
for all purposes of the Merger Agreement as having been paid to the holder of
the Shares in respect of which such deduction and withholding was made by Parent
or the Offeror.
 
6. PRICE RANGE OF SHARES; DIVIDENDS.
 
    According to the Company's Annual Report on Form 10-K for the fiscal year
ended December 31, 1996 (the "1996 10-K"), the Shares are traded on the New York
Stock Exchange (the "NYSE"). The Shares were initially offered to the public on
November 1, 1996 at a price of $23.50 per share. Prior to such date, there was
no public market for the Shares. The following table sets forth for the periods
indicated the high and low sales prices per Share on the NYSE as reported by the
Company in the 1996 10-K with respect to the year ended December 31, 1996, and
as reported by published financial sources with respect to periods after
December 31, 1996.

  Second Quarter (through June 6, 1997)......................................     25 3/4         18
</TABLE>
 
    On June 6, 1997, the last full day of trading prior to the public
announcement of the execution of the Merger Agreement and the commencement of
the Offer, the closing price per Share as reported on the NYSE was $24 7/8.
 
    Since its inception, the Company has not paid cash dividends on its Shares.
 
7. CERTAIN EFFECTS OF THE TRANSACTION.
 
    The purchase of the Shares by the Offeror 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 will adversely affect the liquidity and
market value of the remaining Shares held by stockholders other than the
Offeror. The Company has advised the Offeror that, as of June 5, 1997, there
were approximately 75 holders of record and as of March 31, 1997 there were
approximately 900 beneficial owners of the Shares.
 
    MARKET FOR SHARES.  Depending upon the number of Shares purchased pursuant
to the Offer, the Shares may no longer meet the standards for continued
inclusion on the NYSE. According to the NYSE's published guidelines, the NYSE
would consider delisting such Shares if, among other things, the number of
public holders of 100 Shares or more should fall below 1,200, the number of
publicly held Shares (exclusive of holdings of officers, directors, their
immediate families and other concentrated holdings of 10% 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
$5,000,000. If as a result of the purchase of the Shares pursuant to the Offer
or otherwise, the Shares no longer meet the requirements of the NYSE for
continued listing and the Shares are no longer listed, the market for the Shares
would be adversely affected.
 
    In the event that the Shares should no longer be listed or traded on the
NYSE, it is possible that such Shares would continue to trade in the
over-the-counter market and that price quotations would be reported by other
sources. The extent of the public market for such Shares and the availability of
such quotations would, however, depend upon the number of holders of such Shares
remaining at such time, the
 
                                       10
<PAGE>
interest in maintaining a market in Shares on the part of securities firms, the
possible termination of registration of such Shares under the Exchange Act, as
described below, and other factors.
 
    EXCHANGE ACT REGISTRATION.  The Shares are currently registered under the
Exchange Act. Such registration may be terminated upon application by the
Company to the Commission if there are fewer than 300 record holders of such
Shares. It is the intention of the Offeror to seek to cause an application for
such termination to be made as soon after consummation of the Offer as the
requirements for termination of registration of such Shares are met.
Notwithstanding the termination of registration of the Shares, the Company will
continue to make public disclosure of financial and certain other information in
annual, quarterly and other reports to be filed with the Commission under the
Exchange Act in connection with the Company's 12.75% senior subordinated notes
due March 1, 2005 for so long as such notes remain outstanding.
 
    If registration of the Shares is terminated, the Company would no longer
legally be required to disclose publicly in proxy materials distributed to
stockholders the information which it now must provide under the Exchange Act;
the Company would no longer be subject to Rule 13e-3 under the Exchange Act
relating to "going private" transactions; and the officers, directors and 10%
stockholders of the Company would no longer be subject to the "short swing"
insider trading reporting and profit recovery provisions of the Exchange Act.
Furthermore, if such registration were terminated, persons holding "restricted
securities" of the Company may be deprived of their ability to dispose of such
securities under Rule 144 or Rule 144A promulgated under the Securities Act of
1933, as amended (the "Securities Act").
 
    If registration of the Shares is not terminated prior to the Merger, then
the Shares will be delisted from all stock exchanges and the registration of the
Shares under the Exchange Act will be terminated following the consummation of
the Merger.
 
    MARGIN REGULATIONS.  The Shares are currently "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which has the effect, among other things, of allowing
brokers to extend credit on the collateral of such Shares. Depending upon
factors similar to those described above regarding listing and market
quotations, it is possible that, following the Offer, the Shares would no longer
constitute "margin securities" for the purposes of the margin regulations of the
Federal Reserve Board and therefore could no longer be used as collateral for
loans made by brokers. If registration of Shares under the Exchange Act were
terminated, such Shares would no longer be "margin securities."

- ------------------------
 
(1) As a result of the acquisition by the International Investors of the
    predecessor of the Company from Artemis S.A. (the "1994 Acquisition"), the
    Company's assets and liabilities were adjusted to their estimated fair
    values as of December 2, 1994. In addition, the Company entered into new
    financing arrangements and had a change in its capital structure. Rental
    equipment acquired subsequent to January 1, 1995 is being depreciated over a
    longer useful life. Accordingly, the combined results of the 1994 period and
    subsequent periods are not comparable to prior periods. The period from
    December 2, 1994 to December 31, 1994 reflects increased cost of sales due
    to higher depreciation expense for rental equipment and cost of rental
    equipment sales; increased interest expense; and lower other depreciation
    and amortization. The combined period for 1994 represents the mathematical
    addition of the historical amounts for the Predecessor period (January 1,
    1994 to December 1, 1994) and the Successor period (December 2, 1994 to
    December 31, 1994). Such results may not be indicative of results that would
    have been obtained had the 1994 Acquisition occurred on January 1, 1994.
 
(2) Operating income of the Company is equal to gross profit less selling,
    general, administrative and other expenses and depreciation and amortization
    expense.
 
    The Company is subject to the informational requirements of the Exchange Act
and in accordance therewith files periodic reports, proxy statements and other
information with the Commission relating to its business, financial condition
and other matters. The Company is required to disclose in such proxy statements
certain information, as of particular dates, concerning the Company's directors
and officers, their remuneration, stock options granted to them, the principal
holders of the Company's securities and any material interests of such persons
in transactions with the Company. Such reports, proxy statements
 
                                       12

contains reports and other information regarding registrants that file
electronically with the Commission. Such material may also be inspected at the

    CERTAIN COMPANY PROJECTIONS.
 
    To the knowledge of Parent and the Offeror, the Company does not as a matter
of course make public forecasts as to its future financial performance. However,
in connection with the preliminary discussions concerning the feasibility of the
Offer and the Merger, the Company prepared and furnished Parent with certain
financial projections.
 
    The projections presented in the tables below (the "Projections") are
derived or excerpted from information provided by the Company and are based on
numerous assumptions concerning future events, including acquisitions. The
Projections have not been adjusted to reflect the effects of the Offer or the
Merger or the incurrence of indebtedness in connection therewith. The
Projections should be read together with the other information contained in this

                                       14
<PAGE>
    Except as described in this Offer to Purchase, none of the Offeror, Parent,
or to the best knowledge of the Offeror or Parent, any of the persons listed in
Annex I hereto, owns or has any right to acquire any Shares and none of them has
effected any transaction in the Shares during the past 60 days.
 
    Parent, through certain of its subsidiaries, engages in a number of
transactions with the Company. The Company acts as a distributor of air tools
manufactured by Chicago Pneumatic Tool Company ("CPTC") pursuant to a
Distributor Agreement between the Company and CPTC. In addition, the Company
purchases electric tools from Milwaukee Electric Tool Corporation, and acts as
an agent in connection with the rental of portable oil-free compressors by Atlas
Copco Rental Inc. to end users. These transactions are not material to the
businesses of Parent, its subsidiaries or the Company.
 
    Except as set forth in this Section 9 or elsewhere in this Offer to
Purchase, none of the Offeror, Parent or, to the best knowledge of the Offeror
or Parent, any of the persons listed in Annex I hereto, has any contract,
arrangement, understanding or relationship with any other person with respect to
any securities of the Company, including, but not limited to, any contract,
arrangement, understanding or relationship concerning the transfer or the voting
of any such securities, joint ventures, loan or option arrangements, puts or
calls, guaranties of loans, guaranties against loss or the giving or withholding
of proxies. Except as set forth in this Offer to Purchase, there have been no
contacts, negotiations or transactions between the Offeror or Parent, or, to the

hand, and the Company or its affiliates, on the other hand, concerning a merger,
consolidation or acquisition, a tender offer or other acquisition of securities,
an election of directors or a sale or other transfer of a material amount of
assets. Except as described in this Offer to Purchase, none of the Offeror,
Parent or, to the best knowledge of Parent or the Offeror, any of the persons
listed in Annex I hereto, has had any transaction with the Company or any of its
executive officers, directors or affiliates that would require disclosure under
the rules and regulations of the Commission applicable to the Offer.
 
10. SOURCE AND AMOUNT OF FUNDS.
 
    The total amount of funds required by the Offeror to consummate the Offer
and the Merger is expected to be approximately $915 million, which amount
excludes related fees and expenses.
 
    Parent plans to obtain the necessary funds through capital contributions or
advances made by Atlas Copco. Atlas Copco plans to obtain the funds for such
capital contributions or advances from its available cash and working capital, a
senior revolving credit facility with Merrill Lynch Capital Corporation
("Merrill Lynch Capital") described below, and either through the issuance of
long- or short-term debt securities (including, without limitation, commercial
paper notes) or pursuant to credit facilities that Atlas Copco maintains with
certain commercial banks.
 
    Atlas Copco has received from Merrill Lynch Capital a written financing
commitment to provide $400 million (the "Merrill Lynch Commitment") of an up to
$1.5 billion aggregate principal amount senior revolving credit facility (the
"Credit Facility"). The terms of the definitive agreement providing for the
Credit Facility (the "Loan Agreement") have not yet been finalized. The
following is a summary of the anticipated principal terms of the Credit Facility
based upon the Commitment Letter, dated June 8, 1997, between Atlas Copco and
Merrill Lynch Capital (the "Commitment Letter"). This summary is subject to
finalizing the Loan Agreement, and is qualified in its entirety by reference to
the Commitment Letter, which is filed as an Exhibit to the Schedule 14D-1 and is
incorporated herein by reference.
 
    The Merrill Lynch Commitment is part of the Credit Facility. Although
Merrill Lynch Capital has committed to provide the entire $400 million in
connection with the Offer, Merrill Lynch Capital expects to assemble a syndicate
of financial institutions with respect to the remaining $1.1 billion. The
Merrill Lynch Commitment is not conditioned on the syndication of all or any
portion of the remaining portion of the Credit Facility.
 
                                       15
<PAGE>
    The Credit facility will mature in five years. The Credit Facility will have
no scheduled amortization, but any undrawn portion of the Credit Facility may be
canceled in whole or in part in minimum amounts of $10 million by Atlas Copco
without penalty upon thirty days prior written notice to Merrill Lynch Capital.
The Credit Facility is unsecured.
 
    Borrowings under the Credit Facility will bear interest at a rate equal to
the aggregate of the appropriate London Inter-bank Offered Rate for the relevant
period plus 15.0 basis point, 20.0 basis points or 22.5 basis points depending
upon the credit rating for Atlas Copco's senior unsecured debt during the
relevant period plus, in each case, a utilization fee. The utilization fee of
2.5 basis points per annum is payable quarterly and will be applicable when more
than 50% of the Credit Facility is drawn. Atlas Copco also will pay to Merrill
Lynch Capital commitment, arranger and administration fees, reimburse Merrill
Lynch Capital commitment, arranger and administration fees, reimburse Merrill
Lynch Capital for certain expenses and provide certain indemnities all of which
Parent believes to be customary for commitments of this type.
 
    With regard to the Merrill Lynch Commitment, the Commitment Letter contains,
and the Loan Agreement will contain, conditions precedent, representations and
warranties, covenants (including financial covenants), events of default and
other provisions customary for such financings.
 
    In addition to the use by Atlas Copco of $400 million to provide financing
to Parent and the Offeror in connection with the Offer and the Merger, Atlas
Copco may utilize portions of the funds available under the Credit Facility to
restructure the indebtedness of Atlas Copco, Parent and/or the Company.
 
    Atlas Copco's commercial paper program involves the private placement of
unsecured, commercial paper notes with maturities of up to 360 days. The
commercial paper generally has an effective interest rate approximating the then
market rate of interest for commercial paper of similar rating, currently
approximately 5.75%.
 
    It is anticipated that any indebtedness incurred by Parent in connection
with the transactions contemplated by the Merger Agreement will be repaid from
funds generated internally by Parent and its subsidiaries (including, after the
Merger, if consummated, dividends paid by the Surviving Corporation and its
subsidiaries), through additional borrowings, through application of proceeds of
dispositions or through a combination of two or more such sources. No final
decisions have been made concerning the method Parent will employ to repay any
such indebtedness. Such decisions, when made, will be 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.
 
    The Offer is not conditioned on the obtaining of financing.
 
11. BACKGROUND OF THE OFFER; PAST CONTACTS; TRANSACTIONS OR NEGOTIATIONS WITH
  THE COMPANY.
 
    Beginning in late 1996 Atlas Copco, acting principally through Merrill
Lynch, began to explore the possibility of expanding Parent's (a subsidiary of
Atlas Copco) equipment rental business in the United States through a strategic
acquisition. In February, 1997, Merrill Lynch and Atlas Copco executed an
engagement letter pursuant to which Merrill Lynch was retained by Atlas Copco to
assist in identifying acquisition candidates and in analyzing, structuring,
negotiating and effecting such an acquisition.
 
    From late 1996 through April 1997, the Board of Directors of Atlas Copco was
presented with status reports by its management and by Merrill Lynch on a number
of potential acquisition candidates, and after evaluating various of these
alternatives, in early March 1997 the Company was identified as being well
suited to enable Atlas Copco to achieve its strategic objectives regarding its
equipment rental business.
 
    At a meeting of the Board of Directors of Atlas Copco in April 1997, Merrill
Lynch was authorized to approach Investcorp S.A. ("Investcorp"), as
representative of the International Investors, to discuss a possible acquisition
of the Company by Parent.
 
                                       16
<PAGE>
    On April 28, 1997, representatives of Merrill Lynch met with Mr. Christopher
J. O'Brien, a director of the Company and a member of the Management Committee
of Investcorp, as well as other representatives of Investcorp, to discuss a
possible acquisition of the Company by Parent, and to solicit Investcorp's
interest in such a transaction. Merrill Lynch advised Investcorp that Atlas
Copco was interested in acquiring 100% of the outstanding Shares of the Company
for cash at a per Share price of $30.00.
 
    At a meeting of the Board of Directors of the Company on April 30, 1997, Mr.
O'Brien briefed the Company's directors on Atlas Copco's expression of interest.
Following a discussion of the Atlas Copco expression of interest, the Company's
Board authorized the retention of Credit Suisse First Boston Corporation ("First
Boston") as the Company's financial advisor in evaluating a potential
transaction between the Company and Parent. On May 2, 1997, another meeting of
the Company's Board of Directors, with representatives of First Boston
participating, was held to discuss the potential transaction with Atlas Copco.
At this meeting, a special committee (the "Special Committee") of the Board,
consisting of Mr. Robert Howe as the only director of the Company who is neither
a member of Company management nor affiliated with Investcorp, was formed to
assist the Board in its evaluation of the potential transaction.
 
    During the week of May 5, 1997, representatives of First Boston contacted
representatives of Merrill Lynch and indicated that the Company's Board would
consider an acquisition proposal from Atlas Copco for the Company at $34.00 per
share. In connection with these discussions, it was agreed that certain
information would be provided to Parent for purposes of further evaluating the
Company, and a Confidentiality Agreement was entered into between the Company
and Atlas Copco covering all proprietary and confidential information of the
Company provided or to be provided by or on behalf of the Company to Atlas Copco
in connection with the potential transaction. The Confidentiality Agreement also
contained customary standstill provisions.
 
    On May 14, 1997, Atlas Copco entered into a second engagement letter with
Merrill Lynch pursuant to which Merrill Lynch was retained to assist Atlas Copco
and Parent in connection with a proposed acquisition of the Company.
 
    On May 14 and 15, 1997, representatives of Atlas Copco and Parent attended
meetings at which presentations were made by the Company's management concerning
the Company's business and operations.
 
    On May 26, 1997, Merrill Lynch was authorized by Atlas Copco to explore with
the Company's financial advisors, First Boston, a possible acquisition of the
Company by Atlas Copco or one of its affiliates for cash at a price of $32.00
per share, such proposed acquisition being subject to the prior approval of the
Board of Directors of Atlas Copco and Parent, as well as the completion by
Parent and its financial and legal advisors of certain due diligence
investigative procedures. Merrill Lynch also communicated to First Boston at
such time that, as a part of any such acquisition, Parent would request
nonsolicitation commitments from both the Company and the International
Investors, an option to purchase from the International Investors all of the
International Investor Shares, an irrevocable proxy relating to such Shares, an
option to purchase from the Company additional new Shares equaling 19.9% of the
currently outstanding Shares and the payment by the Company to Parent of certain
fees and expenses of up to four percent of the total equity value of the
transaction in the event that the proposed transaction were to be terminated
prior to completion due to a competing bid. This proposal was communicated by
Merrill Lynch to First Boston on May 27, 1997.
 
    Representatives of the Company, Investcorp and First Boston discussed and
analyzed Atlas Copco's May 27 proposal telephonically and at meetings on May 27
and 28. These discussions included a review of the business and prospects of the
Company, financial and valuation analyses by First Boston and consideration of
the potential that any superior alternative to the Atlas Copco proposal would be
available. In addition to discussions during this time frame among Company
directors which included Mr. Howe, First Boston communicated by telephone
separately with Mr. Howe, as the Special Committee, and with
 
                                       17
<PAGE>
counsel for the Special Committee, with respect to the status of negotiations
and the results of First Boston's financial and valuation analyses to date.
 
    On May 28, 1997, the Company and Investcorp, through First Boston,
communicated their unwillingness to accept the terms outlined in the May 27
proposal. In the alternative, First Boston proposed to Merrill Lynch a purchase
price of $33.00 per share. First Boston also advised Merrill Lynch that, while
the Company and the International Investors would be willing to consider making
nonsolicitation commitments in connection with a proposed transaction with Atlas
Copco, any proposed agreement on the part of the International Investors to
tender the International Investor Shares in connection with such a transaction
should be subject to a right to terminate such agreement and withdraw such
Shares if the Board of Directors of the Company were to withdraw its
recommendation of the proposed Atlas Copco transaction consistent with its
fiduciary duties. First Boston also noted that the option to purchase additional
shares from the Company was not acceptable and proposed that any termination
fees and expenses payable by the Company to Parent be limited to an aggregate of
three percent of the total equity value of the proposed transaction.
 
    Telephonic conferences were held on May 29, 1997, involving various
representatives and advisors of Atlas Copco, the Company and Investcorp during
which Merrill Lynch stated that Atlas Copco was not prepared to pay more than
$32.00 per share, but was willing to forgo the previously requested options to
purchase the International Investor Shares or any Shares from the Company in
favor of an alternative proposal which would call for the International
Investors to pay over to Parent all proceeds above $32.00 per Share of any sale
of the International Investor Shares in any other transaction. Thereafter, First
Boston proposed that the payment to be made by the International Investors for
amounts in excess of $32.00 be limited to amounts less than or equal to $36.00
per Share and that a sharing of proceeds above $32.00 be negotiated.
 
    Telephonic conferences again were held on May 30, 1997 between
representatives of Atlas Copco, the Company, Investcorp, and their respective
financial and legal advisors regarding the terms and conditions of the proposed
acquisition. In the evening of May 30, Atlas Copco, the Company and Investcorp
each expressed a willingness to proceed in the negotiation of the terms and
conditions of the definitive transaction agreements incorporating a per Share
purchase price of $32.00. In addition, such parties each expressed a willingness
to include in the proposed merger agreement a nonsolicitation covenant subject
to the Company Board's right to consider an alternative transaction proposal
consistent with its fiduciary duties and a limitation of three percent of the
total transaction equity value on the fees and expenses payable by the Company
to Parent in the event the proposed transaction were not consummated by reason
of a competitive transaction. Investcorp, on behalf of the International
Investors, also indicated a willingness to negotiate an agreement which would
call for the International Investors to tender the International Investor Shares
in connection with a tender offer by Parent (or one of its subsidiaries) and to
grant to the Parent an irrevocable proxy with respect to such Shares, in each
case subject to certain termination rights, and to make certain payments to
Parent in the event the International Investor Shares were to be sold for a per
share price in excess of $32.00 but only up to $36.00 per share (with a sharing
of such excess in the event Atlas Copco or one of its affiliates were to
purchase the Company at a price above $32.00 due to the presence of a competing
transaction). In addition to the negotiation of the definitive transaction
documents, the execution and delivery of such documents by the parties remained
subject to the approval of the Boards of Directors of Atlas Copco, Parent and
the Company, as well as the completion by representatives and advisors of Atlas
Copco and Parent of their due diligence investigation.
 
    On May 31, 1997, Parent's legal advisors delivered to the Company,
Investcorp, and their respective representatives and advisors initial drafts of
the proposed merger agreement and stockholder agreement incorporating the terms
and conditions discussed on the evening of Friday, May 30.
 
    During the period from May 31, through June 5, 1997, representatives of
Atlas Copco and Parent conducted and completed their due diligence investigation
concerning the Company.
 
                                       18
<PAGE>
    During the period June 2 through June 6, 1997, the respective financial and
legal advisors of Parent, the Company and Investcorp held numerous discussions
regarding the economic and contractual terms of the proposed transactions.
Throughout this period, revised forms of the proposed merger agreement and
stockholder agreement were distributed, reviewed and negotiated by Parent, the
Company, Investcorp and their respective representatives and financial and legal
advisors. Also during this period, in addition to discussions among Company
directors which included Mr. Howe, First Boston updated Mr. Howe, as the Special
Committee, and counsel for the Special Committee regarding the transaction
negotiations and First Boston's continuing financial and valuation analyses.
 
    On June 6, 1997, the Board of Directors of the Company held a meeting during
which it reviewed and unanimously approved, based in part on prior approvals by
the Special Committee on such date, the Stockholder Agreement, the Merger
Agreement and the Offer, subject to confirmation from Atlas Copco on June 8,
1997 that the Board of Directors of Atlas Copco has approved the Stockholder
Agreement, the Merger Agreement and the Offer at an Atlas Copco Board meeting
scheduled for such date. At the June 6, 1997 Company Board meeting, the Board
received and considered reports from the Company's financial advisors, and also
reviewed, considered and discussed the terms of the Stockholder Agreement and
the Merger Agreement, including provisions relating to the ability of the
Company to consider unsolicited third party proposals and to terminate the
Merger Agreement Also at this meeting, First Boston advised the Board that it
was prepared to render its fairness opinion on June 8, 1997 at a Company Board
meeting scheduled to occur promptly after the Atlas Copco Board meeting on that
date.
 
    On June 8, 1997, the Board of Directors of Atlas Copco held a meeting during
which it reviewed and approved the Offer, the Merger Agreement and the
Stockholder Agreement. On the same day, after the Atlas Copco Board approvals,
the Company's Board met and received the written opinion of First Boston to the
effect that, as of the date of such opinion and subject to certain matter set
forth therein, the consideration to be received by the stockholders of the
Company in the Offer and the Merger is fair to such stockholders from a
financial point of view. The Special Committee and the Board of Directors of the
Company then unanimously re-confirmed their prior approvals of the Stockholder
Agreement, the Merger Agreement and the Offer. After the respective June 8
meetings of the Board of Directors of Atlas Copco and the Company, Parent, the
Offeror and the Company executed and delivered the Merger Agreement, and Parent
and the International Investors executed and delivered the Stockholder
Agreement.
 
    Before the opening of trading on the NYSE on the morning of June 9, 1997,
Parent and the Company issued a joint press release announcing the signing of
the definitive Merger Agreement.
 
12. PURPOSE OF THE OFFER AND THE MERGER; PLANS FOR THE COMPANY.
 
    The purpose of the Offer, the Merger, the Merger Agreement and the other
transactions contemplated thereby, is to enable Parent to acquire control of,
and the entire equity interest in, the Company.
 
    Pursuant to the DGCL and the Certificate of Incorporation of the Company,

class or series, is required to approve the Merger Agreement. The Board of
Directors of the Company has unanimously approved the Offer, the Merger and the
Merger Agreement, and, unless the Merger is consummated pursuant to the short
form merger provisions under the DGCL as described below, the only remaining
required corporate action of the Company is the approval of the Merger Agreement
by the affirmative vote of the holders of a majority of the outstanding Shares.
If the Minimum Condition is satisfied, the Offeror will have sufficient voting
power to cause the approval of the Merger Agreement without the affirmative vote
of any other stockholder.
 
    In the Merger Agreement, the Company has agreed that, if approval of the
Merger by stockholders of the Company is required by law, the Company shall, at
Parent's request, as soon as practicable following
 
                                       19
<PAGE>
expiration of the Offer in accordance with the Merger Agreement, duly call, give
notice of, convene and hold a meeting of its stockholders for the purpose of
obtaining the stockholders' approval. Parent has agreed that all Shares owned by
the Offeror or any other subsidiary of Parent will be voted in favor of approval
of the Merger Agreement. The stockholders meeting shall be held as soon as
practicable following the purchase of Shares pursuant to the Offer. If the
Offeror owns a majority of the outstanding Shares, approval of the Merger
Agreement can be obtained without the affirmative vote of any other stockholder
of the Company.
 
    SHORT FORM MERGER.  Under the DGCL, if the Offeror acquires at least 90% of
the outstanding Shares, the Offeror will be able to approve the Merger without a
vote of the Company's stockholders. In such event, the Offeror anticipates that
it will take all necessary and appropriate action to cause the Merger to become
effective as soon as reasonably practicable after such acquisition without a
meeting of the Company's stockholders. If the conditions to the Offeror's
obligation to purchase Shares in the Offer are satisfied prior to the tender of
90% of the outstanding Shares in the Offer, the Offeror may, subject to certain
limitations set forth in the Merger Agreement, delay its purchase of the Shares
tendered to it in the Offer. See Section 1. If the Offeror does not acquire at
least 90% of the outstanding Shares pursuant to the Offer or otherwise, a
significantly longer period of time may be required to effect the Merger,
because a vote of the Company's stockholders would be required under the DGCL.
Pursuant to the Merger Agreement, the Company has agreed to take all action
necessary under the DGCL and its Charter and Bylaws to convene a meeting of its
stockholders promptly following consummation of the Offer to consider and vote
on the Merger, if a stockholders' vote is required. If the Offeror owns a
majority of the outstanding Shares, approval of the Merger can be obtained
without the affirmative vote of any other stockholder of the Company.
 
    APPRAISAL RIGHTS.  No appraisal rights are available in connection with the
Offer. However, if the Merger is consummated, stockholders of the Company will
have certain rights under the DGCL to dissent and demand appraisal of and to
receive payment in cash for 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 (excluding any element of value
arising from the accomplishment or expectation of the Merger) required to be
paid in cash to such dissenting holders of their Shares. In addition, such
dissenting stockholders may 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,
a Delaware court would be 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 earning capacity. In WEINBERGER V. UPO, INC., the
Delaware Supreme 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 admissible in court" should be considered in an
appraisal proceedings. Therefore, the value so determined in any appraisal could
be different from the price being paid in the Offer.
 
    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
and RABKIN V. PHILIP A. HUNT CHEMICAL CORP. that although the remedy ordinarily
available to minority stockholders in a cash out merger is the right to
appraisal described above, a damages remedy or injunctive relief may be
available if a merger is found to be the product of procedural unfairness,
including fraud, misrepresentation or other misconduct.
 
    RULE 13E-3.  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
 
                                       20
<PAGE>
Merger or another business combination in which the Offeror seeks to acquire the
remaining Shares not held by it following the purchase of Shares pursuant to the
Offer. The Offeror believes, however, that Rule 13e-3 will not be applicable to
the Merger if the Merger is consummated within one year after the termination of
the Offer at the Offer Price. If applicable, 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.  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. 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 optimizing
the Company's potential contribution to Parent's business.
 
    Except as indicated in Section 10 or elsewhere in this Offer to Purchase,
Parent does not have any current plans or proposals which relate to or would
result in any of the following: an extraordinary corporate transaction, such as
a merger, reorganization or liquidation involving the Company or any of its
subsidiaries; a sale or transfer of a material amount of assets of the Company
or any of its subsidiaries; any change in the present Board of Directors or
management of the Company; any material change in the Company's present
capitalization or dividend policy; or any other material change in the Company's
corporate structure or business. Notwithstanding the foregoing, following the
acquisition of Shares pursuant to the Offer, the Offeror may designate a
majority of the members of the Board of Directors of the Company. In addition,
assuming the designation of directors as aforesaid and so long as there are
holders of Shares other than Parent or any of its subsidiaries, Parent expects
that the Board of Directors would not declare dividends on the Shares.

    THE MERGER AGREEMENT
 
    THE OFFER.  The Offeror commenced the Offer in accordance with the terms of
the Merger Agreement. Pursuant to the Merger Agreement, the Offeror expressly
reserves the right to modify the terms of the Offer, except that, without the
prior written consent of the Company, the Offeror shall not (i) decrease the
Offer Price, (ii) change the form of consideration to be paid pursuant to the
Offer, (iii) decrease the number of Shares being sought pursuant to the Offer,
(iv) amend or modify any of the conditions to the Offer, (v) impose any
additional conditions to the Offer, (vi) extend the Offer, if all of the Offer
conditions have been satisfied or waived or (vii) amend any other term or
condition of the Offer. Notwithstanding the foregoing, the Offeror may, in its
sole discretion and without the consent of the Company, extend the Offer at any
time and from time to time (i) if at the Expiration Date of the Offer, any of
the conditions to the Offer shall not be satisfied, (ii) for any period required
by applicable law, including, without limitation, any rule, regulation,
interpretation or position of the Commission or the Commission staff applicable
to the Offer or (iii) if on the Expiration Date of the Offer all of the
conditions to the Offer shall have been satisfied or waived but the number of
Shares that have been validly tendered and not withdrawn is less than 90% of the
then outstanding Shares for an aggregate period of not more than five business
days (for all such extensions under this clause (iii)) beyond the latest
expiration date permitted under clause (i) or (ii) of this sentence; provided
that, in the event of any such extension, all of the conditions to the Offer and
to Parent's and the Offeror's obligations to consummate the Merger that have
been satisfied as of such
 
                                       21
<PAGE>
date shall be deemed irrevocably waived by Parent and the Offeror. So long as
the Merger Agreement is in effect and the conditions to the Offer have not been
satisfied or waived, at the request of the Company, the Offeror will extend the
Offer for an aggregate period of not more than five business days (for all such
extensions) beyond the originally scheduled Expiration Date of the Offer.
 
    THE MERGER.  The Merger Agreement provides that, upon the terms and subject
to the conditions of the Merger Agreement, and in accordance with the DGCL, the
Offeror shall be merged with and into the Company at the Effective Time. At the
Effective Time, the separate existence of the Offeror shall cease and the
Company shall continue as the Surviving Corporation under the laws of the State
of Delaware and as a wholly owned subsidiary of Parent. The Merger shall have
the effects set forth in the applicable provisions of the DGCL. At the Effective
Time, and without any further action on the part of the Offeror or the Company,
the Certificate of Incorporation of the Company and the By-laws of the Offeror,
each as in effect immediately prior to the Effective Time, shall be the
Certificate of Incorporation and By-laws of the Company following the Merger
until thereafter amended as provided therein and under the DGCL or applicable
law.
 
    Subject to the provisions described herein under "--REPRESENTATION ON THE
BOARD OF DIRECTORS," the directors of the Company at the Effective Time shall be
the directors of the Company following the Merger, until the earlier of their
resignation or removal or until their respective successors are duly elected and
qualified. The officers of the Company at the Effective Time shall be the
officers of the Company following the Merger, until the earlier of their
resignation or removal or until their respective successors are duly elected or
appointed and qualified.
 
    CONVERSION OF SECURITIES.  As of the Effective Time, by virtue of the Merger
and without any action on the part of the Offeror, the Company or the holders of
any securities of the Offeror or the Company, each Share (other than Shares
owned by the Company, any subsidiary of the Company, Parent, the Offeror, any
other subsidiary of Parent or by stockholders, if any, who are entitled to and
who properly exercise appraisal rights under the DGCL) shall be converted into
the right to receive in cash from the Company following the Merger an amount
equal to the highest price paid per Share pursuant to the Offer without
interest. As of the Effective Time, each share of common stock of the Offeror
issued and outstanding immediately prior to the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any Shares of the
Offeror, shall be converted into one fully paid and non-assessable share of
common stock of the Surviving Corporation.
 
    TREATMENT OF OPTIONS.  Except as otherwise agreed to in writing between the
Company and the holder of any Company Stock Option (as defined below), and as
consented to by Parent, immediately prior to the Effective Time, each
outstanding stock option to purchase Shares held by a current or former employee
or director of the Company or any subsidiary thereof (a "Company Stock Option"),
granted under any stock option or stock purchase plan, program or arrangement of
the Company, whether or not then exercisable, shall be canceled by the Company,
and at the Effective Time or as soon as practicable thereafter, the holder
thereof shall be entitled to receive from the Company in consideration for such
cancellation an amount in cash equal to the product of (i) the number of Shares
previously subject to such Company Stock Option and (ii) the excess, if any, of
the Offer Price over the exercise price per Share, reduced by the amount of
withholding or other taxes required by law to be withheld. Except as provided in
the Merger Agreement or as otherwise agreed by Parent and the Company, the stock
option plans of the Company and any other plan, program or arrangement providing
for the issuance or grant of any other interest in respect of the capital stock
of the Company shall terminate as of the Effective Time.
 
    REPRESENTATION ON THE BOARD OF DIRECTORS.  Promptly upon the acquisition by
the Offeror of such number of Shares constituting a majority of the outstanding
Shares pursuant to the Offer, Parent shall be entitled to designate a majority
of the members of the Company's Board of Directors, subject to compliance with
Section 14(f) of the Exchange Act. The Company, upon request by Parent, shall
promptly increase the size of the Board of Directors and/or secure resignations
of such number of directors as is
 
                                       22
<PAGE>
necessary to enable Parent's designees to be so elected to the Board of
Directors and shall cause Parent's designees to be so elected. Following the
election or appointment of Parent's designees and prior to the Effective Time,
any amendment or termination of the Merger Agreement, extension for performance
or waiver of the obligations or other acts of Parent or the Offeror or waiver of
any of the Company's rights thereunder, shall require the concurrence of a
majority of the Company's directors then in office who were directors on the
date of the Merger Agreement (or directors designated by such persons to fill
any vacancy).

officers, employees, counsel, financial advisors and other representatives to,
afford to Parent and its representative and to potential financing sources
reasonable access during normal business hours to its properties, books,
contracts, commitments, personnel and records, including security position
listings and other information which may be relevant to the Merger or the Offer.
The Offeror, the Company and Parent agreed to hold and cause its respective
representatives to hold any nonpublic information in confidence in accordance
with the Confidentiality Agreement, dated May 6, 1997, between Parent, the
Company and Investcorp International, Inc. (the "Confidentiality Agreement").
 
    NO SOLICITATION.  The Merger Agreement provides that the Company will not

intermediaries), nor will it authorize or permit any of its officers, directors,
agents, representatives or advisors to (a) solicit, initiate or take any action
knowingly to facilitate the submission of inquiries, proposals or offers from

purchase of 20% or more of the consolidated assets of the Company or of over 20%

combination, sale of substantially all assets, recapitalization, liquidation,
dissolution or similar transaction involving the Company other than the
transactions contemplated by the Merger Agreement or (iv) any other transaction

interfere with, prevent or materially delay the Merger or the Offer or which
would or could reasonably be expected to materially dilute the benefits to
Parent of the transactions contemplated by the Merger Agreement (collectively,
"Transaction Proposals"), (b) agree to or endorse any Transaction Proposal or
(c) enter into or participate in any discussions or negotiations regarding any
of the foregoing, or furnish to any other person any information with respect to

Parent) to do or seek any of the foregoing.
 
                                       25
<PAGE>
By the terms of the Merger Agreement, nothing set forth therein will prohibit
the Company (either directly or indirectly through advisors, agents or other
intermediaries) from (i) furnishing information pursuant to an appropriate
confidentiality letter (which letter may not be less favorable to the Company in
any material respect than the confidentiality letter agreement entered into
between the Company and Parent) concerning the Company and its business,
properties or assets to a third party who has offered to make a bona fide
Transaction Proposal, (ii) engaging in discussions or negotiations with such a
third party, (iii) following receipt of a bona fide Transaction Proposal, taking
and disclosing to its stockholders a position contemplated by Rule 14e-2(a)
under the Exchange Act or otherwise making disclosure to its stockholders, (iv)
following receipt of a bona fide Transaction Proposal, failing to make or
withdrawing or modifying its recommendation that the holders of Shares approve
the Merger Agreement, the Merger and the transactions contemplated thereby
and/or (v) taking any non-appealable, final action ordered to be taken by the
Company by any court of competent jurisdiction, but in each case referred to in
the foregoing clauses (i) through (iv) only to the extent that the Board of
Directors of the Company shall have concluded in good faith after consulting
with its outside counsel and financial advisors that such action is consistent
with the discharge of its fiduciary duties to the stockholders of the Company
under applicable law; PROVIDED, that the Board of Directors of the Company is
not permitted to take any of the foregoing actions referred to in clauses (i)
through (v) until after reasonable notice to Parent with respect to such action.
The Company's Board of Directors is further required, to the extent it may do so
without breaching such fiduciary duties, to continue to advise Parent after
taking such action and, in addition, if the Board of Directors of the Company
receives a Transaction Proposal, then the Company is to promptly inform Parent
of the terms and conditions of such proposal and the identity of the person
making it. The Company is required to immediately cease and cause its advisors,
agents and other intermediaries to cease any and all then existing activities,
discussions or negotiations with any parties conducted prior to entering into
the Merger Agreement with respect to any of the foregoing and to use its
reasonable best efforts to cause any such parties in possession of confidential
information about the Company that was furnished by or on behalf of the Company
to return or destroy all such information.
 
    THIRD PARTY CONFIDENTIALITY AND STANDSTILL AGREEMENTS.  Under the Merger
Agreement, the Company has agreed that it will not waive or fail to enforce any
provision of any confidentiality or standstill or similar agreement to which it
is a party without the prior written consent of Parent.
 
    INDEMNIFICATION.  The Merger Agreement provides that the Certificate of
Incorporation and the By-Laws of the Surviving Corporation shall contain the
provisions with respect to indemnification and exculpation from liability set
forth in the Company's Certificate of Incorporation and By-Laws on the date of
the Merger Agreement, which provisions will not be amended, repealed or
otherwise modified for a period of six years from the Effective Time in any
manner that would adversely affect the rights thereunder of individuals who on
or prior to the Effective Time were directors, officers, employees or agents of
Company, unless such modification is required by law.
 
    The Merger Agreement provides that the Company shall maintain in effect for
three years from the Effective Time policies of directors' and officers'
liability insurance containing terms and conditions which are not less
advantageous to the insureds than those policies currently in effect on the date
of the Merger Agreement ("Company Insurance"), with respect to matters occurring
prior to the Effective Time, to the extent available, and having the maximum
available coverage under any such Company Insurance; provided that (i) the
Company following the Merger shall not be required to spend in excess of 150% of
the amount spent by the Company on current annual premiums for Company Insurance
(the "Premium Limit"); provided further that if the Company following the Merger
would be required to spend in excess of the Premium Limit per year to obtain
insurance having the maximum available coverage under the Company Insurance, the
Company will be required to spend up to such amount to maintain or procure
insurance coverage pursuant to the Merger Agreement, subject to availability of
such (or similar) coverage, and (ii) such policies may in the sole discretion of
the Company be one or more "tail" policies for all or any portion of the full
three year period provided that such "tail" policies contain terms and
conditions and
 
                                       26
<PAGE>
provide coverage no less advantageous to the insureds than the terms, conditions
and coverage in the Company Insurance. The Company has agreed that, in the event
it would be required to spend in excess of the Premium Limit per year to obtain
insurance having such maximum available coverage, the Company would notify the
beneficiaries of such policies and permit them to pay any excess which may be

applicable law with respect to all acts and omissions arising out of such
individuals' services as officers, directors, employees or agents of the Company
or as trustees or fiduciaries of any plan for the benefit of employees of the
Company, occurring prior to the Effective Time including, without limitation,
the transactions contemplated by the Merger Agreement. In the event any such
Indemnified Party is or becomes involved in any capacity in any action,
proceeding or investigation in connection with any matter, including without
limitation, the transactions contemplated by the Merger Agreement, occurring
prior to, and including the Effective Time, Parent has agreed that, from and
after the purchase of any Shares pursuant to the Offer, it will pay as incurred,

determine, and such determination shall have become final, that the
indemnification of such Indemnified Party in the manner contemplated by the
Merger Agreement is prohibited by applicable law.

       Proposal by a Third Party other than the Offer and the Merger, or (3)
       publicly resolved to do any of the foregoing; or
 
           (D) the Merger Agreement shall have been terminated in accordance
       with its terms; or
 
           (E) a Material Adverse Effect or Material Adverse Change with respect
       to the Company shall have occurred; or
 
           (F) there shall have occurred and be continuing (i) any general
       suspension of trading in, or limitation on prices for, securities on a
       national securities exchange in the United States (excluding any
       coordinated trading halt triggered solely as a result of a specified
       increase or decrease in a market index or similar "circuit breaker"
       process), (ii) a declaration of a banking moratorium or any suspension of
       payments in respect of banks in the United States, (iii) any material
       limitation (whether or not mandatory) by any governmental entity on, or
       other similar event that materially adversely affects, the extension of
       credit in the United States by banks or other lending institutions or
       (iv) a commencement of a war or armed hostilities or other national or
       international calamity directly or indirectly involving the United States
       which materially adversely affects the extension of credit.
 
    For purposes of the Merger Agreement, "Material Adverse Change" or "Material
Adverse Effect" means any change or effect that either individually or in the
aggregate with all other such changes or effects is materially adverse to the
business, assets, liabilities, financial condition or results of operations of
the subject person, but will exclude any change or effect resulting from general
economic conditions and, in certain instances any occurrence or condition
arising out of the transactions contemplated by the Merger Agreement or the
public announcement thereof.
 
    The foregoing conditions are for the sole benefit of Parent, the Offeror and
their affiliates and may be asserted by Parent or the Offeror regardless of the
circumstances (including any action or inaction by Parent or the Offeror or any
of their affiliates not inconsistent with the terms of the Merger Agreement)
giving rise to such condition. All the foregoing conditions (other than those
described in paragraphs (i) and (iii)(E) above) may be waived by Parent or the
Offeror in whole or in part at any time and from time to time in the sole
discretion of Parent or the Offeror. The failure by Parent or the Offeror at any
time to exercise its rights with respect to the foregoing conditions shall not
be deemed a waiver of any such condition, and each condition shall be deemed an
ongoing condition with respect to which Parent or the Offeror may assert its
rights at any time and from time to time.
 
    Should the Offer be terminated pursuant to the foregoing provisions, all
tendered Shares not theretofore accepted for payment shall forthwith be returned
by the Depositary to the tendering stockholders.
 
16. CERTAIN LEGAL MATTERS.
 
    Except as set forth in this Section, the Offeror is not aware of any
approval or other action by any governmental or administrative agency which
would be required for the acquisition or ownership of Shares
 
                                       34
<PAGE>
by the Offeror as contemplated herein. Should any such approval or other action
be required, it will be sought, but the Offeror has no current intention to
delay the purchase of Shares tendered pursuant to the Offer pending the outcome
of any such matter, subject, however, to the Offeror's right to decline to
purchase Shares if any of the conditions specified in Section 15 shall have
occurred. There can be no assurance that any such approval or other action, if
needed, would be obtained or would be obtained without substantial conditions,
or that adverse consequences might not result to the Company's business or that
certain parts of the Company's business might not have to be disposed of if any
such approvals were not obtained or other action taken.
 
    U.S. ANTITRUST.  Under the provisions of the HSR Act applicable to the
Offer, the acquisition of Shares under the Offer may be consummated following
the expiration of a 15 day waiting period following the filing by Parent of a
Premerger Notification and Report Form with respect to the Offer, unless Parent
receives a request for additional information or documentary material from the
Department of Justice, Antitrust Division (the "Antitrust Division") or the
Federal Trade Commission ("FTC") or unless early termination of the waiting
period is granted. Parent anticipates making its filing on or about June 16,
1997 and, accordingly, the initial waiting period will expire on July 1, 1997.
If, within the initial 15 day waiting period, either the Antitrust Division or
the FTC requests additional information or documentary material concerning the
Offer, the waiting period will be extended through the tenth day after the date
of substantial compliance by all parties receiving such requests. Complying with
a request for additional information or documentary material can take a
significant amount of time.
 
    The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Offeror's proposed acquisition of
the Company. At any time before or after the Offeror's acquisition of Shares
pursuant to the Offer, the Antitrust Division or the FTC could take such action
under the antitrust laws as either deems necessary or desirable in the public
interest, including seeking to enjoin the purchase of Shares pursuant to the
Offer or the consummation of the Merger, or seeking the divestiture of Shares
acquired by the Offeror or the divestiture of substantial assets of the Company
or its subsidiaries or Parent or its subsidiaries. Private parties may also
bring legal action under the antitrust laws under certain circumstances. There
can be no assurance that a challenge to the Offer or the consummation of the
Merger on antitrust grounds will not be made, or, if such a challenge is made,
of the result thereof.
 
    If any applicable waiting period under the HSR Act applicable to the Offer
has not expired or been terminated prior to the Expiration Date, the Offeror
will not be obligated to proceed with the Offer or the purchase of any Shares
not theretofore purchased pursuant to the Offer. See Section 15.
 
    STATE TAKEOVER LAWS.  The Company is incorporated under the laws of the
State of Delaware. In general, Section 203 of the DGCL ("Section 203") prevents
an "interested stockholder" (including a person who owns or has the right to
acquire 15% or more of a corporation's outstanding voting stock) from engaging
in a "business combination" (defined to include mergers and certain other
actions) with a Delaware corporation for a period of three years following the
date such person became an interested stockholder unless, among other things,
the "business combination" is approved by the Board of Directors of such
corporation prior to such date. The Company's Board of Directors has approved
the Offer and the Merger. Accordingly, Section 203 is inapplicable to the Offer
and the Merger. A number of other states have adopted laws and regulations
applicable to attempts to acquire securities of corporations which 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., in
1982, the Supreme Court of the United States (the "U.S. Supreme Court")
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 U.S. Supreme Court held that the State of Indiana
may, as a matter of corporate law and, in particular, with respect to those
aspects of corporate law concerning corporate governance, constitutionally
disqualify a potential acquirer from voting on the affairs of a target
 
                                       35
<PAGE>
corporation without the prior approval of the remaining stockholders. The state
law before the U.S. Supreme Court was by its terms applicable only to
corporations that had a substantial number of stockholders in the state and were
incorporated there.
 
    The Company, directly or through subsidiaries, conducts business in a number
of states throughout the United States, some of which have enacted takeover
laws. The Offeror does not know whether any of these laws will, by their terms,
apply to the Offer or the Merger and has not complied with any such laws. Should
any person seek to apply any state takeover law, the Offeror 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 is 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, the Offeror might be required
to file certain information with, or receive approvals from, the relevant state
authorities. In addition, if enjoined, the Offeror 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 event, the Offeror may not be
obligated to accept for payment any Shares tendered. See Section 15.
 
17. FEES AND EXPENSES.
 
    Neither the Offeror nor Parent, nor any officer, director, stockholder,
agent or other representative of the Offeror or Parent will pay any fees or
commissions to any broker, dealer or other person (other than the Dealer
Manager, 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 the Offeror
for customary mailing and handling expenses incurred by them in forwarding
materials to their customers.
 
    Merrill Lynch is acting as Dealer Manager in connection with the Offer and
is serving as financial advisor to Parent and the Offeror in connection with the
Offer. Parent has agreed to pay Merrill Lynch reasonable and customary
compensation for such services. In addition, Parent has agreed to reimburse
Merrill Lynch for its out of pocket expenses related to its engagement,
including the reasonable fees and expenses of its counsel, and has agreed to
indemnify Merrill Lynch and certain affiliated persons against certain
liabilities and expenses in connection with its services, including, without
limitation, certain liabilities under the federal securities laws.
 
    The Offeror has retained Georgeson & Company Inc. as Information Agent and
The Bank of New York as Depositary in connection with the Offer. The Information
Agent and the Depositary will receive reasonable and customary compensation for
their services hereunder and reimbursement for their reasonable out of pocket
expenses. The Depositary will also be indemnified by the Offeror against certain
liabilities in connection with the Offer. The Information Agent may contact
holders of Shares by mail, telex, telegraph and personal interviews and may
request brokers, dealers and other nominee stockholders to forward materials
relating to the Offer to beneficial owners of Shares.
 
18. MISCELLANEOUS.
 
    The Offer is not being made to, nor will tenders be accepted from or on
behalf of, holders of Shares residing in any jurisdiction in which the making or
acceptance thereof would not be in compliance with the securities, blue sky or
other laws of such jurisdiction. In any jurisdiction where the securities, blue
sky or other laws require the Offer to be made by a licensed broker or dealer,
the Offer shall be deemed to be made on behalf of the Offeror by the Dealer
Manager 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 the Offeror other than as contained in this Offer to
Purchase or in the Letter of Transmittal and, if any such
 
                                       36
<PAGE>
information or representation is given or made, it should not be relied upon as
having been authorized by the Offeror or Parent.
 
    The Offeror and Parent have filed with the Commission the Schedule 14D-1,
pursuant to Section 14(d)(1) of the Exchange Act and Rule 14d-3 promulgated
thereunder, furnishing certain information with respect to the Offer, and a
Schedule 13D, pursuant to Section 13(d)(1) of the Exchange Act and Rule 13d-1
promulgated thereunder, furnishing certain information with respect to Parent's
and the Offeror's beneficial ownership of Shares. The Schedule 14D-1 and any
amendments thereto, including exhibits, may be examined and copies may be
obtained at the same places and in the same manner as set forth with respect to
the Company in Section 8 (except that they will not be available at the regional
offices of the Commission).

Ladies and Gentlemen:
 
    The undersigned hereby tenders to PS Acquisition Corp. (the "Offeror"), a
Delaware corporation and
a wholly owned subsidiary of Atlas Copco North America Inc., a Delaware
corporation ("Parent"), the above-described shares of common stock, $.01 par
value per share of Prime Service, Inc., a Delaware corporation (the "Company"),
(collectively, the "Shares"), pursuant to the Offeror's offer to purchase all of
the outstanding Shares at a purchase price of $32.00 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 June 9, 1997 (the "Offer to
Purchase"), receipt of which is hereby acknowledged, and in this Letter of
Transmittal (which, together with the Offer to Purchase, and any amendments or
supplements hereto or thereto, collectively constitute the "Offer"). The Offer
is being made in connection with the Agreement and Plan of Merger, dated as of
June 8, 1997 (the "Merger Agreement"), among the Parent, the Offeror and the
Company.
 
                                       3

    Subject to and effective upon acceptance for payment of and payment for the
Shares tendered herewith, the undersigned hereby sells, assigns and transfers to
or upon the order of the Offeror all right, title and interest in and to all the
Shares that are being tendered hereby (and any and all other Shares or other
securities issued or issuable in respect thereof) and appoints the Depositary
the true and lawful agent and attorney-in-fact of the undersigned with respect
to such Shares (and all such other Shares or securities), with full power of
substitution (such power of attorney being deemed to be an irrevocable power
coupled with an interest), to (a) deliver certificates for such Shares (and all
such other Shares or securities), or transfer ownership of such Shares (and all
such other Shares or securities) on the account books maintained by any of the
Book-Entry Transfer Facilities, together, in any such case, with all
accompanying evidences of transfer and authenticity, to or upon the order of the
Offeror, (b) present such Shares (and all such other Shares or securities) for
transfer on the books of the Company and (c) receive all benefits and otherwise
exercise all rights of beneficial ownership of such Shares (and all such other
Shares or securities), all in accordance with the terms of the Offer.
 
    The undersigned hereby irrevocably appoints each designee of the Offeror as
the attorney-in-fact and proxy of the undersigned, each with full power of
substitution, to exercise all voting and other rights of the undersigned in such
manner as each such attorney and proxy or his substitute shall in his sole
judgment deem proper, with respect to all of the Shares tendered hereby which
have been accepted for payment by the Offeror prior to the time of any vote or
other action (and any and all other Shares or other securities or rights issued
or issuable in respect of such Shares) at any meeting of stockholders of the
Company (whether annual or special and whether or not an adjourned meeting), any
actions by written consent in lieu of any such meeting or otherwise. This proxy
is irrevocable and is granted in consideration of, and is effective upon, the
acceptance for payment of such Shares by the Offeror in accordance with the
terms of the Offer. Such acceptance for payment shall revoke any other proxy or
written consent granted by the undersigned at any time with respect to such
Shares (and all such other Shares or other securities or rights), and no
subsequent proxies will be given or written consents will be executed by the
undersigned (and if given or executed, will not be deemed effective).
 
    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 any and all other Shares or other securities or rights issued or
issuable in respect of such Shares) and that when the same are accepted for
payment by the Offeror, the Offeror will acquire good and unencumbered title
thereto, free and clear of all liens, restrictions, charges and encumbrances and
not subject to any adverse claims. The undersigned, upon request, will execute
and deliver any additional documents deemed by the Depositary or the Offeror to
be necessary or desirable to complete the sale, assignment and transfer of the
Shares tendered hereby (and all such other Shares or other securities or
rights).
 
    All authority herein conferred or agreed to be conferred shall survive the
death or incapacity of the undersigned, and any obligation of the undersigned
hereunder shall be binding upon the heirs, personal representatives, successors
and assigns of the undersigned. Except as stated in the Offer, 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 an agreement between the undersigned and the
Offeror upon the terms and subject to the conditions of the Offer. The Offeror's
acceptance of such Shares for payment will constitute a binding agreement
between the undersigned and the Offeror upon the terms and subject to the
conditions of the Offer, including, without limitation, the undersigned's
representation and warranty that the undersigned owns the Shares being tendered.
 
    Unless otherwise indicated under "Special Payment Instructions," please
issue the check for the purchase price of any Shares purchased, and return any
certificates evidencing Shares not tendered or not purchased, in the name(s) of
the undersigned. Similarly, unless otherwise indicated under "Special Delivery
Instructions," please mail the check for the purchase price of any Shares
purchased and return any certificates for Shares not tendered or not purchased
(and accompanying documents, as appropriate) to the undersigned at the address
shown below the undersigned's signature(s). In the event that both "Special
Payment Instructions" and "Special Delivery Instructions" are completed, please
issue the check for the purchase price of any Shares purchased and return any
Shares not tendered or not purchased in the name(s) of, and mail said check and
any certificates to, the person(s) so indicated. The undersigned recognizes that
the Offeror has no obligation, pursuant to the "Special Payment Instructions,"
to transfer any Shares from the name of the registered holder(s) thereof if the
Offeror does not accept for payment any of the Shares so tendered.

             FORMING PART OF THE TERMS AND CONDITIONS OF THE OFFER
 
    1.  GUARANTEE OF SIGNATURES.  Except as otherwise provided below, signatures
on all Letters of Transmittal must be guaranteed by a firm that is a bank,
broker, dealer, credit union, savings association or other entity which is a
member in good standing of the Securities Transfer Agents Medallion Program, the
New York Stock Exchange Medallion Signature Guarantee Program, the Stock
Exchange Medallion Program, or by any other bank, broker, dealer, credit union,
savings association or other entity which is an "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 constituting an
"Eligible Institution"), unless the Shares tendered thereby are tendered (i) by
a registered holder of Shares who has not completed either the box labeled
"Special Payment Instructions" or the box labeled "Special Delivery
Instructions" on the Letter of Transmittal or (ii) for the account of an
Eligible Institution. See Instruction 5. If the certificates are registered in
the name of a person or persons other than the signer of this Letter of
Transmittal, or if payment is to be made or delivered to, or certificates
evidencing unpurchased Shares are to be issued or returned to, a person other
than the registered owner or owners, then the tendered certificates must be
endorsed or accompanied by duly executed stock powers, in either case signed
exactly as the name or names of the registered owner or owners appear on the
certificates or stock powers, with the signatures on the certificates or stock
powers guaranteed by an Eligible Institution as provided herein. See Instruction
5.
 
    2.  DELIVERY OF LETTER OF TRANSMITTAL AND SHARES.  This Letter of
Transmittal is to be used either if certificates are to be forwarded herewith
or, unless an Agent's Message (as defined in the Offer to Purchase) is utilized,
if the delivery of Shares is to be made by book-entry transfer pursuant to the
procedures set forth in Section 3 of the Offer to Purchase. Certificates for all
physically delivered Shares, or a confirmation of a book-entry transfer into the
Depositary's account at one of the Book-Entry Transfer Facilities of all Shares
delivered electronically, as well as a properly completed and duly executed
Letter of Transmittal (or a manually signed facsimile thereof) and any other
documents required by this Letter of Transmittal, or an Agent's Message in the
case of a book-entry delivery, must be received by the Depositary at one of its
addresses set forth on the front page of this Letter of Transmittal by the
Expiration Date. If certificates are forwarded to the Depositary in multiple
deliveries, a properly completed and duly executed Letter of Transmittal must
accompany each such delivery. Stockholders who cannot deliver their Shares and
all other required documents to the Depositary by the Expiration Date must
tender their Shares pursuant to the guaranteed delivery procedures set forth in
Section 3 of the Offer to Purchase. Pursuant to such procedures: (a) such tender
must be made by or through an Eligible Institution; (b) a properly completed and
duly executed Notice of Guaranteed Delivery, substantially in the form provided
by the Offeror, must be received by the Depositary prior to the Expiration Date;
and (c) the certificates for all tendered Shares, in proper form for tender, or
a confirmation of a book-entry transfer into the Depositary's account at one of
the Book-Entry Transfer Facilities of all Shares delivered electronically, as
well as a properly completed and duly executed Letter of Transmittal (or a
manually signed facsimile thereof), and any other documents required by this
Letter of Transmittal must be received by the Depositary within three trading
days after the date of execution of such Notice of Guaranteed Delivery, all as
provided in Section 3 of the Offer to Purchase. The term "trading day" is any
day on which the New York Stock Exchange is open for business.
 
    THE METHOD OF DELIVERY OF CERTIFICATES EVIDENCING SHARES, THE LETTER OF
TRANSMITTAL AND ALL OTHER REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH A
BOOK-ENTRY TRANSFER FACILITY, IS AT THE OPTION AND RISK OF THE TENDERING
STOCKHOLDER. SHARES WILL BE DEEMED DELIVERED ONLY WHEN ACTUALLY RECEIVED BY THE
DEPOSITARY (INCLUDING, IN THE CASE OF A BOOK-ENTRY TRANSFER, BY A CONFIRMATION
OF A BOOK-ENTRY TRANSFER). 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.
 
                                       6
<PAGE>
    No alternative, conditional or contingent tenders will be accepted, and no
fractional Shares will be purchased. By executing this Letter of Transmittal (or
a manually signed facsimile thereof), the tendering stockholder waives any right
to receive any notice of the acceptance for payment of the Shares.
 
    3.  INADEQUATE SPACE.  If the space provided herein is inadequate, the
certificate numbers and/or the number of Shares should be listed on a separate
schedule attached hereto.
 
    4.  PARTIAL TENDERS (NOT APPLICABLE TO STOCKHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER).  If fewer than all the Shares represented by any certificate
delivered to the Depositary are to be tendered, fill in the number of Shares
which are to be tendered in the box entitled "Number of Shares Tendered." In
such case, a new certificate for the remainder of the Shares represented by the
old certificate will be sent to the person(s) signing this Letter of Transmittal
unless otherwise provided in the appropriate box on this Letter of Transmittal,
as promptly as practicable following the expiration or termination of the Offer.
All Shares evidenced by certificates delivered to the Depositary will be deemed
to have been tendered unless otherwise indicated.
 
    5.  SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND ENDORSEMENTS.  If
this Letter of Transmittal is signed by the registered holder(s) of the Shares
tendered hereby, the signature(s) must correspond with the name(s) as written on
the face of the certificates without alteration, enlargement or any change
whatsoever.
 
    If any of the Shares tendered hereby are held 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 different names on
different certificates, it will be necessary to complete, sign and submit as
many separate Letters of Transmittal as there are different registrations of
certificates.
 
    If this Letter of Transmittal is signed by the registered holder(s) of the
Shares tendered hereby, no endorsements of certificates or separate stock powers
are required unless payment of the purchase price is to be made, or certificates
evidencing Shares not tendered or not purchased are to be returned, in the name
of any person other than the registered holder(s), in which case the
certificate(s) for such 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 the certificate for such Shares.
Signatures on any such certificates or 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 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(s) on the certificates
for such Shares. Signature(s) on any such certificates or stock powers must be
guaranteed by an Eligible Institution.
 
    If this Letter of Transmittal or any certificate evidencing Shares or stock
power is signed by a trustee, executor, administrator, guardian,
attorney-in-fact, officer of a corporation or other person acting in a fiduciary
or representative capacity, such person should so indicate when signing, and
proper evidence satisfactory to the Offeror of the authority of such person so
to act must be submitted.
 
    6.  STOCK TRANSFER TAXES.  Except as otherwise provided in this Instruction
6, the Offeror will pay any 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 is to be made to, or Shares not tendered or not
purchased are to be returned in the name of, any person other than the
registered holder(s), then 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 person will be deducted from the purchase price
unless satisfactory evidence 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 certificates listed in this Letter of
Transmittal.
 
                                       7
<PAGE>
    7.  SPECIAL PAYMENT AND DELIVERY INSTRUCTION.  If the check for the purchase
price of any Shares purchased is to be issued, or any Shares not tendered or not
purchased are to be returned, in the name of a person other than the person(s)
signing this Letter of Transmittal or if the check or any certificates for
Shares not tendered or not purchased are to be mailed to someone other than the
person(s) signing this Letter of Transmittal or to the person(s) signing this
Letter of Transmittal at an address other than that shown above, the appropriate
boxes on this Letter of Transmittal should be completed. Stockholders tendering
Shares by book-entry transfer may request that Shares not purchased be credited
to such account at any of the Book-Entry Transfer Facilities as such stockholder
may designate under "Special Payment Instructions." If no such instructions are
given, any such Shares not purchased will be returned by crediting the account
at the Book-Entry Transfer Facilities designated above.
 
    8.  SUBSTITUTE FORM W-9.  The tendering stockholder is required to provide
the Depositary with such stockholder's correct TIN on Substitute Form W-9, which
is provided below, unless an exemption applies. Failure to provide the
information on the Substitute Form W-9 may subject the tendering stockholder to
a $50 penalty and to 31% federal income tax backup withholding on the payment of
the purchase price for the Shares.
 
    9.  FOREIGN HOLDERS.  Foreign holders must submit a completed IRS Form W-8
to avoid 31% backup withholding. IRS Form W-8 may be obtained by contacting the
Depositary at one of the addresses on the face of this Letter of Transmittal.
 
    10.  REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Questions and requests
for assistance may be directed to the Dealer Manager or the Information Agent 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.
 
    11.  WAIVER OF CONDITIONS.  The conditions of the Offer may be waived by the
Offeror (subject to certain limitations in the Merger Agreement), in whole or in
part, at any time or from time to time, in the Offeror's sole discretion.
 
    12.  LOST, DESTROYED OR STOLEN CERTIFICATES.  If any certificate
representing Shares has been lost, destroyed or stolen, the stockholder should
promptly notify the Depositary. The stockholder will then be instructed as to
the steps that must be taken in order to replace the certificate. This Letter of
Transmittal and related documents cannot be processed until the procedures for

HEREOF (TOGETHER WITH CERTIFICATES OR CONFIRMATION OF BOOK-ENTRY TRANSFER AND
ALL OTHER REQUIRED DOCUMENTS) OR A NOTICE OF GUARANTEED DELIVERY MUST BE
RECEIVED BY THE DEPOSITARY ON OR PRIOR TO THE EXPIRATION DATE (AS DEFINED IN THE
OFFER TO PURCHASE).
 
                           IMPORTANT TAX INFORMATION
 
    Under federal income tax law, a stockholder whose tendered Shares are
accepted for payment is required to provide the Depositary with such
stockholder's correct TIN on the Substitute Form W-9. 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.
 
    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, that stockholder must submit a statement, signed under penalties of
 
                                       8
<PAGE>
perjury, attesting to that individual's exempt status. Such statements may be
obtained from the Depositary. All exempt recipients (including foreign persons
wishing to qualify as exempt recipients) should see the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional instructions.
 
    If backup withholding applies, the Depositary is required to withhold 31% of
any payments made to the 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 backup withholding results in an
overpayment of taxes, a refund may be obtained.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
    To prevent backup federal income tax 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 certifying that the TIN provided on the Substitute
Form W-9 is correct.
 
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 owner of the Shares. 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 guidelines on which number to
report.

    NOTE: You may be subject to backup withholding if this interest is $600 or
      more and is paid in the course of the payer's trade or business and you
      have not provided your correct taxpayer identification number to the
      payer.
 
    - Payments of tax-exempt interest (including exempt-interest dividends under
      section 852).

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, AND
RETURN IT TO THE PAYER. IF THE PAYMENTS ARE INTEREST, DIVIDENDS OR PATRONAGE
DIVIDENDS, ALSO SIGN AND DATE THE FORM.

PRIVACY ACT NOTICE.--Section 6109 requires most recipients of dividend, interest
or other payments to give taxpayer identification numbers to payers who must
report the payments to the 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, dividend 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 INFORMATION WITH RESPECT TO WITHHOLDING.--If you
make a false statement with no reasonable basis which results in no imposition
of backup withholding, you are subject to a penalty of $500.
 
(3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.-- Falsifying certifications or
affirmations may subject you to criminal penalties including fines and/or
imprisonment.
 
FOR ADDITIONAL INFORMATION CONTACT YOUR TAX CONSULTANT OR THE INTERNAL REVENUE
SERVICE.

("Parent"), is offering to purchase all of the shares of common stock, par 
value $.01 per share, of Prime Service, Inc., a Delaware corporation (the

to the seller in cash, without interest thereon, upon the terms and subject 
to the conditions set forth in the Offer to Purchase, dated June 9, 1997 (the 
"Offer to Purchase"), and in the related Letter of Transmittal (which, 
together with any amendments or supplements thereto, collectively constitute 
the "Offer"). 

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT, NEW YORK CITY 
TIME, ON MONDAY, JULY 7, 1997, UNLESS THE OFFER IS EXTENDED.

the purchase of Shares pursuant to the Offer and the satisfaction of the

<PAGE>

For purposes of the Offer, the Offeror will be deemed to have accepted for 
payment, and thereby purchased, Shares validly tendered and not properly 
withdrawn as, if and when the Offeror gives oral or written notice to The 
Bank of New York (the "Depositary") of the Offeror's acceptance of such 
Shares for payment pursuant to the Offer. In all cases, payment for Shares 
purchased pursuant to the Offer will be made by deposit of the purchase price 
with the Depositary, which will act as agent for tendering stockholders for 
the purpose of receiving payment from the Offeror and transmitting such 
payment to tendering stockholders. Under no circumstances will interest be 
paid by the Offeror because of any delay in making any payment. Payment for 
Shares tendered and accepted for payment pursuant to the Offer will be made 
only after timely receipt by the Depositary of (i) certificates for such 
Shares or timely confirmation of a book-entry transfer of such Shares into 
the Depositary's account at the Book-Entry Transfer Facilities (as defined in 
the Offer to Purchase), pursuant to the procedures set forth in the Offer to 
Purchase, (ii) a properly completed and duly executed Letter of Transmittal 
(or manually signed facsimile thereof) with all required signature guarantees 
or, in the case of a book-entry transfer, an Agent's Message (as defined in 
the Offer to Purchase) and (iii) any other documents required by the Letter 
of Transmittal.

If any of the conditions set forth in the Offer to Purchase that relate to 
the Offeror's obligations to purchase the Shares are not satisfied by 12:00 
Midnight, New York City time, on Monday, July 7, 1997 (or any other time then 
set as the Expiration Date), the Offeror may, subject to the terms of the 
Merger Agreement as described below, elect to (i) extend the Offer and, 
subject to applicable withdrawal rights, retain all tendered Shares until the 
expiration of the Offer, as extended, (ii) subject to complying with 
applicable rules and regulations of the Securities and Exchange Commission, 
accept for payment all Shares so tendered and not extend the Offer or (iii) 
terminate the Offer and not accept for payment any Shares and return all 
tendered Shares to tendering stockholders. The term "Expiration Date" means 
12:00 Midnight, New York City time, on Monday, July 7, 1997, unless the 
Offeror shall have extended the period of time for which the Offer is open, 
in which event the term "Expiration Date" shall mean the latest time and date 
at which the Offer, as so extended by the Offeror, shall expire. 

Subject to the limitations set forth in the Offer and the Merger Agreement, 
the Offeror reserves the right (but will not be obligated), at any time or 
from time to time in its sole discretion, to extend the period during which 
the Offer is open by giving oral or written notice of such extension to the 
Depositary and by making a public announcement of such extension. Except to 
the extent required by the Merger Agreement, there can be no assurance that 
the Offeror will exercise its right to extend the Offer. Any extension of the 
period during which the Offer is open will be followed, as promptly as 
practicable, by public announcement thereof, such announcement to be issued 
not later than 9:00 a.m., New York City time, on the next business day after 
the previously scheduled Expiration Date. 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.

Except as otherwise provided in Section 4 of the Offer to Purchase, tenders 
of Shares made pursuant to the Offer are irrevocable. Shares tendered 
pursuant to the Offer may be withdrawn at any time prior to the Expiration 
Date and, unless theretofore accepted for payment pursuant to the Offer, may 
also be withdrawn at any time after August 7, 1997. For a withdrawal of 
Shares tendered pursuant to the Offer to be effective, a written, 
telegraphic, telex or facsimile transmission notice of withdrawal must be 
timely received by the Depositary at one of its addresses set forth on the 
back cover of the Offer to Purchase. Any notice of withdrawal must specify 
the name of the person who

<PAGE>

tendered the Shares to be withdrawn, the number of Shares to be withdrawn and 
the name in which the certificates representing such Shares are registered, 
if different from that of the person who tendered the Shares. If certificates 
for Shares to be withdrawn have been delivered or otherwise identified to the 
Depositary, then, prior to the physical release of such certificates, the 
serial numbers shown on such certificates must be submitted to the Depositary 
and, unless such Shares have been tendered by an Eligible Institution (as 
defined in the Offer to Purchase), the signatures on the notice of withdrawal 
must be guaranteed by an Eligible Institution. If Shares have been tendered 
pursuant to the procedures for book-entry transfer set forth in the Offer to 
Purchase, any notice of withdrawal must also specify the name and number of 
the account at the Book-Entry Transfer Facility to be credited with the 
withdrawn Shares. All questions as to the form and validity (including time 
of receipt) of notices of withdrawal will be determined by the Offeror, in 
its sole discretion, and its determination will be final and binding on all 
parties.

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

The Company has provided to the Offeror its lists of stockholders and 
security position listings for the purpose of disseminating the Offer to 
holders of Shares. The Offer to Purchase, the related Letter of Transmittal 
and other related materials are being mailed to record holders of Shares and 
will be mailed to brokers, dealers, commercial banks, trust companies and 
similar persons whose names, or the names of whose nominees, appear on the 
stockholder lists or, if applicable, who are listed as participants in a 
clearing agency's security position listing, for subsequent transmittal to 
beneficial owners of Shares.

THE OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT 
INFORMATION THAT SHOULD BE READ BEFORE ANY DECISION IS MADE WITH RESPECT TO 
THE OFFER. 

Questions and requests for assistance may be directed to the Dealer Manager 
or the Information Agent at their respective addresses as set forth below.

JOINT RELEASE

                        PRIME SERVICE, INC. TO BE ACQUIRED BY
                            ATLAS COPCO NORTH AMERICA INC.
                                FOR $32 CASH PER SHARE
                                           
     Stockholm, Sweden and Houston, Texas, June 9, 1997 --- Prime Service, Inc. 
(NYSE: PRS), one of the largest rental equipment companies in the United States,
announced today that it has entered into a definitive merger agreement with
Atlas Copco North America Inc., a subsidiary of Sweden based Atlas Copco AB,
pursuant to which Atlas Copco will acquire all outstanding shares of Prime
Service at a price of $32.00 per share in cash. The aggregate consideration of
the transaction to Prime Service shareholders is approximately $900 million
(exclusive of approximately $260 million in debt.)

Pursuant to the agreement, Atlas Copco will commence a cash tender offer on 
June 9, 1997 for all of Prime Service's approximately 28 million shares. The 
agreement also provides that Prime Service shares not acquired by Atlas Copco 
in the tender offer will be converted into the right to receive $32.00 in 
cash per share in a merger to be completed following consummation of the 
tender offer. The boards of directors of both Prime Service and Atlas Copco 
have approved the transaction. The Prime Service board has received an 
opinion from Credit Suisse First Boston that the consideration to be received 
by the Prime Service shareholders pursuant to the tender offer and merger is 
fair to such holders from a financial point of view. The acquisition is 
subject to antitrust approvals and other customary conditions.

Prime Service was acquired in December 1994 by Investcorp, certain international
investors and Prime Service management. At the time, Prime Service had
approximately $212 million in revenues. The company completed an initial public
offering in October 1996. Investcorp and the other international investors, who
currently own approximately 74 per cent of the outstanding shares of Prime
Service, have agreed to tender all of their shares as a part of the Atlas Copco
acquisition. 

Thomas E. Bennett, Chairman of the Board and Chief Executive Officer of Prime
Service, said, "We are extremely excited about this new partnership with Atlas
Copco, with its long history of solid growth and premier product lines. As
before, we will continue to enhance our customer relationships, grow our rental
fleet and improve our market coverage."

Giulio Mazzalupi, President and Chief Executive Officer of Atlas Copco AB, said,
"It is a strategic goal for Atlas Copco to increase revenues generated from the
use of our products, including accessories, service and rental operations. Prime
Service, with its highly developed service ability, is part of this strategy and
is an excellent fit to our existing business in the U.S."

In the U.S. market, there is a trend towards renting construction and industrial
equipment driven primarily by the desire to concentrate on core activity and
always have the state of the art equipment. In the last five years it is
estimated that the rental industry has grown about 20 per cent per year.
Analysts estimate that the contractor rental market in the U.S. alone exceeds
$18 billion.

"The acquisition increases the opportunity to develop our business in the United
States, to be close to the customers, and to enhance the growth potential of
Atlas Copco products. Atlas Copco will also achieve a leading position in
service of construction and industrial equipment in the U.S.," comments Giulio
Mazzalupi.

Christopher J.O'Brien, a member of Investcorp's Management Committee and a
Director of Prime Service said, "We have enjoyed our association with Prime
Service, and are proud to have participated in the growth of this premier
company. We are very pleased that Prime Service shareholders will realize an
excellent return on their investment in Prime Service." On June 6, 1997, Prime
Service's shares closed at a price of $24 7/8 per share.

Prime Service is one of the leaders in the rental equipment industry in the
United States, and currently operates 122 rental equipment locations in 14
states. Prime Service rents over 100 different types of equipment, including
aerial manlifts, portable air compressors, forklifts and light earth moving
equipment, as well as small equipment such as power tools. Prime Service has a
base of over 40,000 customers ranging from Fortune 500 companies to
subcontractors and homeowners. Total revenue for 1996 was approximately $330
million.

Atlas Copco, based in Sweden, is an international industrial group of companies
and is among the world's leading suppliers of products and services in the areas
of air and gas compression, industrial manufacturing, rock excavation, light
construction and demolition, as well as installation, repair and service. Atlas
Copco has approximately 21,000 employees worldwide, and had sales in 1996 of
approximately $3.6 billion. Atlas Copco North America Inc. is the holding
company for well-known U.S. companies including Milwaukee Electric Tool
Corporation and Chicago Pneumatic Tool Company.

Investcorp was established in 1982. It acts as a principal and an intermediary
in international investment transactions. To date, it has completed over 60
transactions with an acquisition value of approximately $9 billion. Investcorp
and its clients currently own 16 corporate investments in North America and
Europe, including Saks Fifth Avenue, Star Markets, Simmons Company, William
Carter Company, Helly Hansen and CSK Auto. Previous investments include Tiffany,
Gucci, Circle K and Thorn Lighting.

Atlas Copco AB
105 23 Stockholm, Sweden
Attention:  Hans Ola Meyer, Director
Re: Commitment Letter

Ladies and Gentlemen:

         Atlas Copco AB (the "Company") has advised Merrill Lynch Capital
Corporation ("Merrill Lynch") that it intends, directly or indirectly, to
acquire (the "Acquisition") all of the issued and outstanding capital stock of a
company previously identified to us as Pinta (the "Target") pursuant to a merger
agreement (the "Merger Agreement") to be entered into among the Company and a
wholly-owned subsidiary of the Company formed to effect the Acquisition
("Acquisition Sub"), and the Target.  We understand that the Acquisition will
take the form of a tender offer (the "Tender Offer") by Acquisition Sub for all
of the issued and outstanding shares of common stock of the Target (all of such
common stock collectively, the "Shares") and the purchase of the portion of the
Shares tendered and not withdrawn pursuant to the Tender Offer (the "Tendered
Shares"), which purchase shall be subject to the condition that not less than
that number of the Shares (on a fully diluted basis) which would entitle the
Company to approve the Merger without the affirmative vote of any other
securityholder or any other person be tendered and not withdrawn pursuant to the
Tender Offer. You have advised Merrill Lynch that certain holders of not less
than 70% of the outstanding Shares have agreed to tender such Shares in the
Tender Offer.  We further understand that the Tender Offer price will not exceed
$32 per Share and the aggregate purchase price for all of the Shares will not
exceed $950,000,000.  We further understand that, in connection with the
launching of the Tender Offer, the Company intends to give notice to the lenders
thereunder of its intention to repay all indebtedness (and terminate all
commitments to make extensions of credit) under the existing $250,000,000
syndicated credit facility of the Company agented 

<PAGE>

                                      -2-


by Enskilda (the "Refinanced Debt").  In addition, after consummation of the 
Tender Offer the Company intends to (x) repay (including by tender offer (the 
"Note Tender Offer")) the existing public debt securities (the "Public 
Notes") of the Target aggregating approximately $67,000,000, or make other 
arrangements satisfactory to Merrill Lynch with respect to the Public Notes, 
and (y) repay all indebtedness and terminate all commitments to make 
extensions of credit under all credit arrangements of the Target and its 
subsidiaries, aggregating approximately $160,000,000 (the transactions in 
clauses (x) and (y), the "Target Debt Repayment").

         The Acquisition, the Target Debt Repayment, the Tender Offer, the 
repayment of all debt and cancellation of all commitments to make extensions 
of credit under the Refinanced Debt (the "Existing Debt Repayment"), and the 
entering into and borrowings under the Credit Facility herein described are 
herein referred to as the "Transactions."  Pursuant to the Merger Agreement, 
after the consummation of the Tender Offer, Acquisition Sub will merge (the 
"Merger") into the Target and the Target will be the survivor.  We further 
understand that the precise structure of the Transactions will be under 
continuing consideration, may vary from the foregoing and will be subject to 
our mutual agreement.

         You have advised Merrill Lynch that the total consideration necessary 
to effect the Transactions will not exceed $1,450,000,000 (excluding fees and 
expenses).

         You have requested that Merrill Lynch commit to provide to the 
Company $400,000,000 of an up to $1,500,000,000 aggregate principal amount of 
senior revolving credit facility (the "Credit Facility"), of which up to 
$100,000,000 will be available as a U.S. dollar swing line subfacility 
(appropriately adjusted to reflect the actual size of the Credit Facility).  
It is anticipated that drawings under the Credit Facility will be available 
to be made in the currencies specified in the Term Sheet (as defined below).

         You have advised Merrill Lynch that the Company may issue commercial 
paper in an amount sufficient to effect the Transactions, in which event the 
Credit Facility would be available as a backup for such commercial paper 
issuance.  You have advised Merrill Lynch that no other financing other than 
the Company's commercial paper program and/or the Credit Facility will be 
incurred or be necessary to effect the Transactions.

         Accordingly, subject to the terms and conditions set forth below, 
Merrill Lynch hereby agrees with you as follows:

<PAGE>

                                      -3-

         1. Commitment.  Merrill Lynch hereby commits to the Company to provide
$400,000,000 of the Credit Facility to the Company and to use its best efforts
to assemble a syndicate of financial institutions (together with Merrill Lynch,
the "Lenders") to provide the balance of the Credit Facility ($1,100,000,000),
in each case upon the terms and subject to the conditions set forth or referred
to herein, in the fee letter (the "Fee Letter") dated the date hereof and
delivered to you and in the Summary of Terms and Conditions attached hereto (and
incorporated by reference herein) as Exhibit A (the "Term Sheet").  The initial
extensions of credit under the Credit Facility will occur not earlier than
simultaneously with the consummation of the Tender Offer and the Existing Debt
Repayment.  If the size of the Credit Facility exceeds $400,000,000, the
syndication and allocations of such commitments in excess of $400,000,000
related to such Credit Facility shall be satisfactory to Merrill Lynch and the
Borrower.  Merrill Lynch reserves the right to designate any of its affiliates
to fund Merrill Lynch's commitment hereunder.

         It is a condition of Merrill Lynch's commitment hereunder that Merrill
Lynch act as sole and exclusive arranger of  and syndication agent for (the
"Arranger") the Credit Facility, it being understood and agreed that the
Arranger will perform all functions and exercise all authority (including,
without limitation, (a) serving as sole manager of the syndication effort,
(b) selecting counsel for the Arranger, and (c) negotiating definitive
documentation for the Credit Facility (the "Credit Documents")) customarily
performed and exercised by agent banks in such capacity.  The appointment of any
co-agents for the Credit Facility would be subject to the prior approval of
Merrill Lynch.  The co-agent title and other titles awarded to syndicate
participants would not entail any role with respect to the matters referred to
in this paragraph without the prior consent of Merrill Lynch.  Merrill Lynch may
select after consultation with you Lenders reasonably acceptable to you to act
as a facility agent (in such capacity, the "Facility Agent") to perform such
ministerial and administrative functions as Merrill Lynch, in its reasonable
discretion, may desire and as swing line agent (the "Swing Line Agent") to
perform swing line facility functions under the Credit Facility.

         2.   Syndication.  Merrill Lynch reserves the right and intends, 
prior to or after the execution of the Credit Documents, to syndicate all or 
a portion of its commitment to one or more Lenders that will become parties 
to the Credit Documents, and in that connection, promptly following your 
acceptance of Merrill Lynch's commitment hereunder, Merrill Lynch will 
commence the syndication of the Credit Facility to such Lenders.  You agree 
that no Lender will receive compensation outside the terms contained herein 
and in the Fee Letter in order to obtain its commitment to 

<PAGE>

                                      -4-

participate in the Credit Facility.  It is understood and agreed that, except 
as otherwise provided in the Fee Letter, the amount and distribution of the 
fees and other compensation referred to herein among the Lenders and to any 
Administrative Agent (or any co-agent) will be at Merrill Lynch's sole 
discretion.  It is understood and agreed that Merrill Lynch will manage all 
aspects of the syndication (but will consult with you in such matters), 
including, without limitation, decisions as to the selection of potential 
Lenders reasonably acceptable to you to be approached and when they will be 
approached, when their commitments will be accepted, which Lenders will 
participate, any naming rights (including the naming of co-agents, subject to 
your reasonable approval) and the final allocations of the commitments among 
the Lenders.

         You agree actively to assist Merrill Lynch in achieving a timely
syndication that is satisfactory to Merrill Lynch.  The syndication efforts will
be accomplished by a variety of means, including direct contact during the
syndication between senior management (including,
but not limited to, the chief executive officer, chief financial officer and
treasurer of the Company and/or the Target) and advisors and affiliates of the
Company and/or the Target on the one hand and the proposed syndicate Lenders on
the other hand.  To assist Merrill Lynch in its syndication efforts, you agree
that you will, promptly, upon Merrill Lynch's request, (a) provide, and cause
your affiliates and advisors to provide, and use your best efforts to have the
Target provide, to Merrill Lynch all information reasonably deemed necessary by
Merrill Lynch to complete successfully the syndication, including but not
limited to, information and projections (including, without limitation, any
updated projections requested by Merrill Lynch) prepared by you or on your
behalf relating to the transactions contemplated hereby, and (b) to assist, and
to cause your affiliates and advisors to assist, and use your best efforts to
have the Target assist, Merrill Lynch in the preparation of a confidential
information memorandum and other marketing materials to be used in connection
with the syndication, including making available representatives of the Company
and/or the Target and their respective subsidiaries.  You also agree to use your
best efforts to ensure that Merrill Lynch's syndication efforts benefit from
your existing lending relationships.  Your assistance in connection with the
syndication will also include, if Merrill Lynch so requests, your assisting
Merrill Lynch in obtaining for the Company (at the sole expense of the Company)
credit ratings from one or more nationally recognized rating agencies.  You
further agree that Merrill Lynch shall have a reasonable period of time to
syndicate the Credit Facility and, in any event, shall not be obligated to make
any advances under the Credit Facility (x) until the date which is at least 23
business days following the effectiveness of a definitive merger agreement with
respect to the Acquisi-

<PAGE>

                                      -5-

tion, or (y) if the information memorandum described above is not distributed 
to prospective Lenders within eight business days following such 
effectiveness. It is understood and agreed that Merrill Lynch shall be 
entitled, with your prior written consent (which shall not be unreasonably 
withheld or delayed), to change the structure and terms and provisions of the 
Credit Facility as described herein and in the Term Sheet (provided that the 
aggregate principal amount of the Credit Facility, taken as a whole, remains 
the same) if Merrill Lynch deems such action advisable in order to ensure a 
successful syndication (including Merrill Lynch achieving a hold level 
acceptable to Merrill Lynch and the Company) or an optimal credit structure.

         3.   Fees.  As consideration for Merrill Lynch's commitment hereunder
and its agreement to arrange, manage and structure the Credit Facility and its
agreement to use its best efforts to syndicate the Credit Facility, you agree to
pay to Merrill Lynch the fees as set forth in the Term Sheet and in the Fee
Letter.  You agree that, once paid, such fees and any part thereof shall be
nonrefundable under any and all circumstances and regardless of whether the
transactions or borrowings contemplated hereby are consummated.  All such fees
shall be paid by wire transfer of immediately available funds in United States
dollars and free of all withholding taxes (for which you agree to indemnify the
recipient thereof).

         4.   Conditions.  Merrill Lynch's commitment hereunder is subject to
the negotiation, execution and delivery of definitive Credit Documents
satisfactory in all respects to Merrill Lynch and its counsel.  Such definitive
documentation shall reflect the terms and conditions set forth herein and in the
Term Sheet and contain such other indemnities, covenants, representations and
warranties, events of default, conditions precedent, security arrangements and
other terms and conditions as are satisfactory to Merrill Lynch and the Company,
modified as appropriate to reflect the terms of the Transactions and the
financial condition of the Company, the Target and their respective
subsidiaries.  Our willingness to provide our commitment in respect of the
Credit Facility is further subject to review of the Merger Agreement, tender
offer documents and other documents relating to the Acquisition and the other
Transactions and to our reasonable satisfaction with the terms and conditions
thereof (including the price of the Note Tender Offer) and that the Company and

terms and conditions of the Credit Documents shall not be inconsistent with the
terms and conditions set forth herein or in the Term Sheet).

         Merrill Lynch's commitment hereunder is also subject to (a) there
shall not have occurred or become known (i) in the judgment of Merrill Lynch any
material adverse change (or any development involving a prospective material
adverse change) or any condition or event that could reasonably be expected to
result in a material adverse change in the business, assets, liabilities
(contingent or otherwise), operations, condition (financial or otherwise),
solvency, properties or material agreements of the Company or the Target,
individually or together with their respective subsidiaries taken as a whole, as
the case may be (and before and after giving effect to the Transactions), in
each case since the date of the latest audited financial statements of the
Company and the Target, respectively, delivered to Merrill Lynch, (ii) any facts
or circumstances discovered by Merrill Lynch in the course of its ongoing due
diligence investigation of the Company, the Target and the Transactions,
including (without limitation) its review of the historical, pro forma and
projected consolidated financial statements of the Company and/or the Target and
their respective subsidiaries, which (x) Merrill Lynch believes could,
individually or in the aggregate, have a material adverse effect on the
Transactions or the business, assets, liabilities (contingent or otherwise),
operations, condition (financial or otherwise), solvency, properties or material
agreements of the Company or the Target, individually or together with their
respective subsidiaries taken as a whole, as the case may be (and before and
after giving effect to the Transactions) or (y) would be materially inconsistent
with the assumptions underlying the Projections (as defined below in Section 5),
(iii) any transaction (other than the Transactions) entered into by the Company
or the Target or any of their respective subsidiaries, whether or not in the
ordinary course of business, that in Merrill Lynch's judgment is material to the
Company or the Target, individually or together with their respective
subsidiaries, taken as a whole, or (iv) any dividend or distribution of any kind
declared or paid by the Company or the Target on its capital stock not in the
ordinary course; (b) no material adverse change (or development involving a
prospective material adverse change) shall have occurred in the United States or
English loan syndication or financial, banking, currency or capital market
conditions generally from those in effect on the date hereof that, individually
or in the aggregate, in the judgment of Merrill Lynch could reasonably be
expected to adversely affect the consummation of the Transactions or the other
transactions contemplated by this Commitment Letter or adversely affect the
ability of Merrill Lynch to successfully syndicate the Credit Facility (it being
understood that the consummation of a successful syndication is not a condition
to Merrill Lynch's commitment hereunder); no banking moratorium shall have been
declared by United States Federal, English or New York State banking authorities
and shall be continuing; (c) the Target, the Company and their respective

<PAGE>

                                      -7-

subsidiaries shall not have syndicated or issued, attempted to syndicate or 
issue, announced or authorized the announcement of the syndication or 
issuance of, or engaged or discussion concerning the syndication or issuance 
of, any debt facility or debt security of the Target, the Company or any of 
their respective subsidiaries, including renewals thereof, except that the 
Company may continue and increase its existing commercial paper program, 
backstopped on and after the date of execution and delivery of the Credit 
Documentation (the "Closing Date") only by the Credit Facility; and (d) the 
satisfaction of the other terms and conditions set forth or referred to 
herein (including, without limitation, those set forth in Sections 1, 2 and 
5) and in the Term Sheet.  For purposes of this Commitment Letter and the 
Term Sheet, the "subsidiaries" of the Company shall be deemed to include 
those who will become subsidiaries of the Company in connection with the 
Transactions.

         5.   Information and Investigations.  You hereby represent and
covenant that (a) all information and data (excluding financial projections)
concerning the Company, its subsidiaries, the Target, the Transactions and the
other transactions contemplated hereby (the "Information") that have been made
or will be prepared by or on behalf of you or any of your affiliates or
authorized representatives or advisors and that have been or will be made
available to Merrill Lynch by you or on your behalf in connection with the
transactions contemplated hereby, taken as a whole, is and will be complete and
correct in all material respects and does not and will not, taken as a whole,
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements contained therein not misleading
in light of the circumstances under which such statements are made, and (b) all
financial projections concerning the Company, the Target, their respective
subsidiaries and the transactions contemplated hereby (the "Projections") that
have been prepared by or on behalf of you or any of your affiliates or
authorized representatives and that have been or will be made available to
Merrill Lynch by you or on behalf of you or any of your affiliates or authorized
representatives or advisors in connection with the transactions contemplated
hereby have been and will be prepared in good faith based upon assumptions
believed by you to be reasonable.  You agree to supplement the Information and
the Projections from time to time until the Closing Date and, if requested by
Merrill Lynch, for a reasonable period thereafter necessary to complete the
syndication of the Credit Facility so that the representation and covenant in
the preceding sentence remain correct.  In arranging the Credit Facility,
including the syndication thereof, Merrill Lynch will be using and relying
primarily on the Information and the Projections without independent check or
verification thereof.

         Merrill Lynch has completed a substantial portion of its due diligence
investigation of the Company and the Target and is pleased to confirm that it is
satisfied with the results thereof to date.  However, we will need the
opportunity to complete the remaining portion of our due diligence efforts
necessary to substantiate the financial, legal and factual premises upon which
our commitment is based.  Merrill Lynch's commitment hereunder is based upon the
accuracy and completeness of the financial and other information provided to us
by or on behalf of you and is subject to Merrill Lynch being afforded the
opportunity to complete the remainder of its customary due diligence
investigation with respect to each of the Company, the Target, their respective
subsidiaries, the Transactions, including (without limitation) in respect of
business, financial, tax, accounting, environmental, and other contingent
obligation matters, and other structural, legal and regulatory matters.  If
Merrill Lynch's ongoing due diligence investigation discloses information, or
Merrill Lynch otherwise discovers information not previously disclosed to it,
that Merrill Lynch believes has had or could have, individually or in the
aggregate, a materially adverse impact on the business, assets, liabilities
(contingent or otherwise), operations, condition (financial or otherwise),
solvency, properties or material agreements of the Company or the Target,
individually or together with their respective subsidiaries taken as a whole, as
the case may be (and before and after giving effect to the Transactions), or on
the tax or accounting consequences of the Transactions, then Merrill Lynch (a)
shall be entitled to decline to participate in the financing contemplated hereby
or (b) may, in its sole discretion, suggest alternative financing amounts or
structures that ensure adequate protection for Merrill Lynch and the other
Lenders.  In any such event, Merrill Lynch shall not be responsible or liable
for any damages which may be alleged as a result of its failure, in accordance
with the terms of this Commitment Letter, to provide its commitment in respect
of the Credit Facility.

         6.   Indemnification.  By executing this Commitment Letter, you agree
to indemnify and hold harmless Merrill Lynch and each of the other Lenders and
their respective officers, directors, employees, affiliates, agents and
controlling persons (Merrill Lynch and each such other person being an
"Indemnified Party") from and against any and all losses, claims, damages and
liabilities, joint or several, to which any such Indemnified Party may become
subject arising out of or in connection with or relating to this Commitment
Letter, the Fee Letter, the Term Sheet, the Credit Facility, the loans under the
Credit Facility, the use of proceeds of any such loan, any of the Transactions
or any related transaction and the performance by Merrill Lynch or any of its
affiliates of the services contemplated by this Commitment Letter and will
reimburse any Indemnified Party for any and all reasonable expenses (including
counsel fees and expenses) as they are 


<PAGE>
                                       -9-

incurred in connection with the investigation of or preparation for or 
defense of any pending or threatened claim or any action or proceeding 
arising therefrom, whether or not such Indemnified Party is a party and 
whether or  not such claim, action or proceeding is initiated or brought by 
or on behalf of the Company or any of its affiliates and whether or not any 
of the transactions contemplated hereby are consummated or this Commitment 
Letter is terminated.  You will not be liable under the foregoing 
indemnification provision to an Indemnified Party to the extent that any 
loss, claim, damage, liability or expense is found in a final non-appealable 
judgment by a court of competent jurisdiction to have resulted primarily from 
such Indemnified Party's willful misconduct, bad faith or gross negligence.

         You also agree that no Indemnified Party shall have any liability 
(whether direct or indirect, in contract or tort or otherwise) to the 
Company, the Target or their respective security holders or creditors related 
to or arising out of or in connection with this Commitment Letter, the Fee 
Letter, the Term Sheet, the Credit Facility, the loans under the Credit 
Facility, the use of proceeds of any such loan, any of the Transactions or 
any related transaction or the performance by Merrill Lynch or any of its 
affiliates of the services contemplated by this Commitment Letter, except to 
the extent that any loss, claim, damage or liability is found in a final 
non-appealable judgment by a court of competent jurisdiction to have resulted 
primarily from such Indemnified Party's willful misconduct, bad faith or 
gross negligence.

         You agree that, without Merrill Lynch's prior written consent, you
will not settle, compromise or consent to the entry of any judgment in any
pending or threatened claim, action or proceeding in respect of which
indemnification has been or could be sought under the indemnification provisions
of this Commitment Letter (whether or not Merrill Lynch or any other Indemnified
Party is an actual or potential party to such claim, action or proceeding),
unless such settlement, compromise or consent (i) includes an unconditional
written release in form and substance satisfactory to the Indemnified Parties of
each Indemnified Party from all liability arising out of such claim, action or
proceeding and (ii) does not include any statement as to an admission of fault,
culpability or failure to act by or on behalf of any Indemnified Party.

         In the event that an Indemnified Party is requested or required to
appear as a witness in any action brought by or on behalf of or against you or
any of your affiliates in which such Indemnified Party is not named as a
defendant, you agree to reimburse Merrill Lynch for all reasonable expenses
incurred by it in connection with such Indemnified Party's appearing and

<PAGE>
                                       -10-

preparing to appear as such a witness, including, without limitation, the fees
and disbursements of its legal counsel.

         7.   Costs and Expenses.  By executing this Commitment Letter, you
agree to reimburse Merrill Lynch and its affiliates upon request made from time
to time for their reasonable out-of-pocket expenses (including, without
limitation, expenses of Merrill Lynch's due diligence investigation,
consultants' fees (if such consultants are engaged by Merrill Lynch with your
consent (which consent shall not be unreasonably withheld or delayed)),
syndication expenses, appraisal and valuation fees and expenses, travel
expenses, and the reasonable fees, disbursements and other charges of counsel)
incurred in connection with the Credit Facility and the negotiation,
preparation, execution and delivery, waiver or modification, administration,
collection and enforcement of this Commitment Letter, the Term Sheet, the Fee
Letter, the Credit Documents and the security arrangements in connection
therewith.

         8.   Confidentiality.  You agree that this Commitment Letter, the Term
Sheet, the Fee Letter, the contents of any of the foregoing and Merrill Lynch's
and/or its affiliates' activities pursuant hereto or thereto is confidential and
shall not be disclosed by you to any person without the prior written consent of
Merrill Lynch, other than your officers, directors, employees, accountants,
attorneys and other advisors, and then only in connection with the Transactions
and on a confidential and need-to-know basis, except that, following your
acceptance hereof (and payment of any fees due and payable upon such acceptance
as set forth in the Fee Letter), you may (x) make such filings of this
Commitment Letter and the Term Sheet (but not the Fee Letter or any information
regarding any matter related to the Fee Letter) with the United States
Securities and Exchange Commission (the "SEC") as are required by the United
States federal securities laws and applicable rules and regulations thereunder
in connection with the Tender Offer and the Merger and describe the contents of
this Commitment Letter and the Term Sheet (but not the Fee Letter or any
information regarding any matter related to the Fee Letter) in any document
filed by the Company with the SEC in connection therewith, and (y) provide a
copy of this Commitment Letter and the Term Sheet (but not the Fee Letter or any
information regarding any matter related to the Fee Letter) on a confidential
basis to the Target and their respective officers, directors, employees,
accountants, attorneys and other advisors, and you may make such other public
disclosures of the terms and conditions hereof as you are required by applicable
law or compulsory legal process to make; provided, however, that if such
disclosure is required by applicable law or compulsory legal process you agree
to give Merrill Lynch reasonable notice to afford Merrill Lynch the opportunity
to seek a protective order and to cooperate with Merrill Lynch in securing


<PAGE>

                                     -11-

such a protective order.  You agree that you will permit Merrill Lynch to 
review and approve any reference to Merrill Lynch in connection with the 
Credit Facility or the transactions contemplated hereby contained in any 
press release or similar public disclosure prior to public release.

         9.   Termination.  In the event that (i) you have not accepted this
Commitment Letter by June 9, 1997 or executed a definitive Merger Agreement with
the Target in form and substance acceptable to Merrill Lynch on or prior to
June 9, 1997; (ii) the Closing Date does not occur on or before July 31, 1997;
(iii) any circumstance described in clause (a), (b), or (c) of the second
paragraph of Section 4 shall have occurred; (iv) the Tender Offer is terminated
without any Shares being purchased and the abandonment of the effort to acquire
the Target; or (v) the Target accepts an acquisition or recapitalization
proposal other than that of the Company or upon the termination of an executed
acquisition agreement between the Company and the Target, this Commitment Letter
and Merrill Lynch's commitment hereunder shall terminate (upon written notice by
Merrill Lynch with respect to clause (ii) of this sentence) unless Merrill Lynch
shall, in its discretion, agree to an extension.  Notwithstanding the foregoing,
the compensation, reimbursement, indemnification and confidentiality provisions
hereof and of the Term Sheet and the  Fee Letter and Sections 11 and 14 of this
Commitment Letter shall survive any termination of this Commitment Letter or
Merrill Lynch's commitment hereunder.

         10.  Assignment, Etc.  This Commitment Letter and Merrill Lynch's
commitment hereunder shall not be assignable by either party hereto without the
prior written consent of the other party hereto, and any attempted assignment
shall be void and of no effect; provided, however, that nothing contained in
this Section shall prohibit Merrill Lynch (in its sole discretion) from
(i) performing any of its duties hereunder through any of its affiliates,
including Merrill Lynch, Pierce, Fenner & Smith Incorporated, and you will owe
any related duties (including those set forth in Section 2 above) to any such
affiliate, and (ii) granting participations in, or selling assignments of all or
a portion of, the commitments or the loans under the Credit Facility pursuant to
arrangements satisfactory to Merrill Lynch.  This Commitment Letter is intended
to be solely for the benefit of the parties hereto and is not intended to confer
any benefits upon, or create any rights in favor of, any person other than the
parties hereto.

         11.  GOVERNING LAW.  THIS COMMITMENT LETTER SHALL BE GOVERNED BY, AND
CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (WITHOUT REGARD
TO PRINCIPLES OF CONFLICTS OF LAW).  The Company hereby irrevocably submits to
the jurisdiction of any New York State or Federal 


<PAGE>
                                       -12-

court sitting in The City of New York, New York County, in any action or 
proceeding arising out of or relating to this Commitment Letter or the Fee 
Letter, and the Company hereby irrevocably agrees that all claims in respect 
of such action or proceeding may be heard and determined in such New York 
State court or such Federal court.  The Company hereby irrevocably waives, to 
the fullest extent it may effectively do so, the defense of an inconvenient 
forum to the maintenance of such action or proceeding.  The Company hereby 
irrevocably consents to the service of copies of any summons and complaint 
and any other process which may be served in any such action or proceeding by 
certified mail, return receipt requested, or by delivering a copy of such 
process to the Company, at its address specified in Section 16 or by any 
other method permitted by law.  The Company agrees that a final judgment in 
any such action or proceeding shall be conclusive and may be enforced in 
other jurisdictions by suit on the judgment or by any other manner provided 
by law.

         12.  Execution in Counterparts.  This Commitment Letter may be
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement.  Delivery of an executed counterpart of this Commitment Letter by
telecopier shall be effective as delivery of a manually executed counterpart of
this Commitment Letter.

         13.  Amendments, Etc.  No amendment or waiver of any provision of this
Commitment Letter, nor any consent or approval to any departure therefrom, shall
in any event be effective unless the same shall be in writing and signed by the
parties hereto and then any such waiver, consent or approval shall be effective
only in the specific instance and for the specific purpose for which given.  By
executing this letter, you acknowledge that this Commitment Letter and the Fee
Letter are the only agreements between you and Merrill Lynch with respect to the
Credit Facility and set forth the entire understanding of the parties with
respect thereto.

         14.  Waiver of Jury Trial.  Each of you and Merrill Lynch (in each
case on its own behalf and, to the extent permitted by applicable law, on behalf
of its shareholders) waives all right to trial by jury in any action, proceeding
or counterclaim (whether based upon contract, tort or otherwise) related to or
arising out of any of the Transactions, the other transactions contemplated by,
or the performance by Merrill Lynch or any of its affiliates of the services
contemplated by, this Commitment Letter.

         15.  Public Announcements.  You acknowledge that Merrill Lynch may, at
its option and expense, place an announcement 

<PAGE>
                                       -13-

in such newspapers and periodicals as it may choose, stating that Merrill 
Lynch has acted in the capacity set forth in this Commitment Letter.

         16.  Notices.  Any notice given pursuant to any of the provisions of
this agreement shall be in writing and shall be mailed or delivered, if to you,

                             reduced return involved in continuing to provide 
                             the Facility to the Borrower, and may (without 
                             prejudice to its obligation to make such payment):

                             and Supervisory Practices.

Illegality:                  In the event that it becomes illegal for any 
                             Bank to lend or maintain its commitment, the 
                             Borrower shall repay that Bank and/or that 
                             Bank's commitment will be cancelled.

ATLAS COPCO NORTH AMERICA INC., a Delaware corporation ("Parent"), PS 
ACQUISITION CORP., a Delaware corporation and a wholly-owned subsidiary of 
Parent ("Newco"), and PRIME SERVICE, INC., a Delaware corporation ("Company").

         WHEREAS, the respective Boards of Directors of Parent, Newco and 
Company have approved, and deem it advisable and in the best interests of 
their respective stockholders to consummate, the business combination 
contemplated hereby upon the terms and subject to the conditions set forth 
herein;

         WHEREAS, it is intended that the business combination contemplated 
hereby be accomplished by Newco commencing a cash tender offer to purchase 
all of the issued and outstanding shares of common stock, par value $0.01 per 
share, of Company (the "Company Common Stock"), to be followed by a merger of 
Newco with and into Company, with Company being the surviving corporation and 
a wholly-owned subsidiary of Parent, all upon the terms and subject to the 
conditions set forth herein;

         WHEREAS, Parent, Newco and Company desire to make certain 
representations, warranties, covenants and agreements in connection with the 
transactions contemplated hereby and also to prescribe various conditions to 
the transactions contemplated hereby;

         WHEREAS, concurrently with the execution and delivery of this 
Agreement, Parent is entering into an agreement with certain stockholders of 
Company (the "Stockholder Agreement") pursuant to which, among other things, 
such stockholders shall agree to take certain actions to support the 
transactions contemplated by this Agreement;

         NOW, THEREFORE, in consideration of the premises and the 
representations, warranties, covenants and agreements herein contained, the 
parties agree as follows:

                                      ARTICLE I.

                                      THE OFFER

         SECTION 1.01.  The Offer.

         (a)  Subject to the provisions of this Agreement, as soon as 
practicable, but in no event later than five (5) business days from the date 
hereof, Newco shall commence (within the meaning of Rule 14d-2 under the 
Securities Exchange Act of 1934, as amended 

<PAGE>


(the "Exchange Act")) an offer to purchase all outstanding shares of Company 
Common Stock at a price per share of $32.00 net to the seller in cash, 
without interest, subject only to all of the conditions set forth herein and 
in Annex I (together with any amendments or supplements thereto, the 
"Offer").  The per share amount shall be net to the seller in cash, upon the 
terms and subject to the conditions of the Offer and subject to reduction for 
any applicable federal, state, local or foreign back-up or other applicable 
withholding or stock transfer taxes.  Subject to the provisions of this 
Agreement and the conditions set forth in Annex I, Newco shall keep the Offer 
open until at least midnight, New York City time, on the date twenty (20) 
business days from the date of its commencement.  As soon as legally 
permissible after such date and time, Newco will accept for payment all 
shares of Company Common Stock validly tendered pursuant to the Offer and not 
withdrawn and pay for all such shares of Company Common Stock as promptly as 
practicable thereafter, in each case upon the terms and subject to the 
conditions of the Offer.  The obligations of Newco to accept for payment and 
to pay for any shares of Company Common Stock validly tendered shall be 
subject only to the conditions set forth in Annex I.  The Offer shall be made 
by means of an offer to purchase (the "Offer to Purchase") containing the 
terms set forth in this Agreement and the conditions set forth in Annex I.

         (b)  Newco expressly reserves the right to waive any conditions to 
the Offer, in whole or in part at any time or from time to time, in its sole 
discretion (other than the conditions set forth in clauses (i) and (iii)(D) 
of Annex I), to increase the price per share payable in the Offer, to extend 
the duration of the Offer, or to make any other changes in the terms and 
conditions of the Offer; provided, however, that without the prior written 
consent of Company, Newco shall not (i) decrease the price per share of 
Company Common Stock being offered pursuant to the Offer, (ii) change the 
form of consideration to be paid pursuant to the Offer, (iii) decrease the 
number of shares of Company Common Stock being sought pursuant to the Offer, 
(iv) amend or modify any of the conditions to the Offer set forth in Annex I, 
(v) impose any additional conditions to the Offer, (vi) extend the Offer, if 
all of the Offer conditions are satisfied or waived, or (vii) amend any other 
term or condition of the Offer.  Notwithstanding anything to the contrary 
contained herein, Newco may, in its sole discretion and without the consent 
of Company, extend the Offer at any time and from time to time (A) if at the 
then scheduled expiration date of the Offer any of the conditions set forth 
in Annex I have not been satisfied, (B) for any period required by applicable 
law, including, without limitation, any rule, regulation, interpretation or 
position of the Securities and Exchange Commission (the "SEC") or its staff 
applicable to the Offer and (C) if all Offer conditions are satisfied or 
waived but the number of shares of Company Common Stock tendered is less than 
90% of the then outstanding number of shares of Company Common Stock, for an 
aggregate period of not more than 5 business days (for all such extensions 
under this clause (C)) beyond the latest expiration date that would be 
permitted under clause (A) or (B) of this sentence; provided, however, that 
in the event of any extension pursuant to clause (C), all conditions set 
forth in Annex I which would have been satisfied if the Offer had been 
consummated on the date of such extension shall be deemed irrevocably waived 
by Parent and Newco.  So long as this Agreement is in effect and the 
conditions to the Offer have not been satisfied or waived, at the request of 
Company, Newco shall extend the Offer for an aggregate period of not more 
than five business days (for all such extensions) beyond the originally 
scheduled expiration 

                                         -2-

date of the Offer.  It is agreed that the conditions to the Offer are for the 
benefit of Parent and Newco and may be asserted by Parent or Newco regardless 
of the circumstances giving rise to any such condition (including any action 
or inaction by Parent or Newco not inconsistent with the terms hereof).

         (c)  Parent and Newco shall file with the SEC as soon as practicable 
on the date the Offer is commenced, a Tender Offer Statement on Schedule 
14D-1 with respect to the Offer (together with all amendments and supplements 
thereto and including the exhibits thereto, the "Schedule 14D-1") which shall 
include, as exhibits, the Offer to Purchase and a form of letter of 
transmittal and summary advertisement, and other ancillary Offer documents 
and instruments pursuant to which the Offer will be made (the Schedule 14D-1, 
together with any amendments and supplements thereto, the "Offer Documents"). 
 Each of Parent and Newco agrees to take all steps necessary to cause the 
Offer Documents to be filed with the SEC and to be disseminated to Company's 
stockholders, in each case as and to the extent required by applicable 
federal securities laws and any other applicable law.  Each of Parent and 
Newco, on the one hand, and Company, on the other hand, agrees promptly to 
correct any information provided by it for use in the Offer Documents if and 
to the extent that it shall have become false and misleading in any material 
respect, and Parent and Newco further agree to take all steps necessary to 
cause the Offer Documents as so corrected to be filed with the SEC and to be 
disseminated to Company's stockholders, in each case as and to the extent 
required by applicable federal securities laws and any other applicable law.  
Company and its counsel shall be given the opportunity to review the Offer 
Documents before they are filed with the SEC.  In addition, Parent and Newco 
agree to provide Company and its counsel in writing with any comments Parent, 
Newco or their counsel may receive from time to time from the SEC or its 
staff with respect to the Offer Documents promptly after the receipt of such 
comments.  Company shall cooperate with Parent and Newco in responding to any 
comments received from the SEC with respect to the Offer and amending the 
Offer in response to any such comments.

         (d)  Subject to the terms and conditions of the Offer, Parent shall 
provide or cause to be provided to Newco on a timely basis the funds 
necessary to accept for payment, and pay for, shares of Company Common Stock 
that Newco becomes obligated to accept for payment, and pay for, pursuant to 
the Offer.

         SECTION 1.02.  Company Actions.

         (a)  Company hereby approves of and consents to the Offer and 
represents that (i) its Board of Directors, at a meeting duly called and

the best interests of Company and Company's stockholders, (B) approved this 
Agreement and the transactions contemplated hereby (including the Offer and

Stockholder Agreement, and the transactions contemplated hereby and thereby 
and (D) resolved to recommend that the stockholders of Company accept the 
Offer, tender all their shares of Company Common Stock pursuant to the Offer 
and approve and adopt this Agreement and the transactions contemplated hereby

amended, but only to the extent that Company complies with the provisions of 
Section 6.07) and (ii) Credit Suisse First Boston Corporation ("First 
Boston") has rendered to the Board of Directors of Company its opinion, as 
described in Section 4.01(o).  Company hereby consents to the inclusion in

Boston to the inclusion in the Schedule 14D-9 (as defined in Section 1.02(b)) 
of a copy of the written opinion referred to in clause (ii) above.

         (b)  Upon commencement of the Offer, Company shall promptly file 
with the SEC a Solicitation/Recommendation Statement on Schedule 14D-9 
(together with all amendments and supplements thereto and including the 
exhibits thereto, the "Schedule 14D-9") which shall contain the 
recommendation referred to in clause (i)(D) of Section 1.2(a); provided, 
however, that such recommendation may be modified, withdrawn or amended, but 
only to the extent that Company complies with the provisions of Section 6.07. 
 Company agrees to take all steps necessary to cause the Schedule 14D-9 to be 
filed with the SEC and to be disseminated to Company's stockholders, in each 
case as and to the extent required by applicable federal securities laws and 
any other applicable law.  Each of Company, on the one hand, and Parent and 
Newco, on the other hand, agrees promptly to correct any information provided 
by it for use in the Schedule 14D-9 if and to the extent that it shall have 
become false and misleading in any material respect, and Company further 
agrees to take all steps necessary to cause the Schedule 14D-9 as so

filed with the SEC.  In addition, Company agrees to provide Parent and its 
counsel in writing with any comments Company or its counsel may receive from

promptly after the receipt of such comments.  Parent and Newco shall 
cooperate with Company in responding to any comments received from the SEC

security position listings and any available listing or computer file 
containing the names and addresses of the record holders of the shares of 
Company Common Stock as of a recent date, and shall furnish Newco with such 
information and assistance (including updated information) as Newco or its 
agents may reasonably request in communicating the Offer to Company's 
stockholders.  Parent and Newco agree to use such materials only in 
connection with the Offer and the Merger, and, if this Agreement shall be 
terminated, will promptly return all copies of such materials then in their 
possession or control (or the possession or control of their agents or 
representatives) to

Stock and from time to time thereafter, Parent shall be entitled to designate 
a majority of the members of Company's Board of Directors, subject to 
compliance with Section 14(f) of the Exchange Act.  Company shall, upon 
request by Parent, promptly increase the size of the Board of Directors, to 
the extent permitted by its Certificate of Incorporation, and/or secure the

action necessary to effect any such election, including mailing to its 
stockholders the information required by Section 14(f) of the Exchange Act

and Company shall permit the remaining Continuing Director to appoint his 
successor in his reasonable discretion.  

         (b)  Following the election or appointment of Parent's designees 
pursuant to this Section 1.03 and prior to the Effective Time (as defined in 
Section 2.03), any amendment or termination of this Agreement, extension for 
the performance or waiver of the obligations or other acts of Parent or Newco

                                         -6-


<PAGE>



         SECTION 3.01.  Effect on Capital Stock.  As of the Effective Time, 
by virtue of the Merger and without any action on the part of Company, Newco 
or any holder of any shares of Company Common Stock or any shares of capital 
stock of Newco:

         (a) Common Stock of Newco.  Each share of common stock of Newco 
issued and outstanding immediately prior to the Effective Time shall be 
converted into one fully paid and non-assessable share of common stock par 
value $0.01 of the Surviving Corporation.

         (b) Cancellation of Treasury Stock and Parent-Owned Company Common 
Stock.  Each share of Company Common Stock that is owned by Company or by any 
Subsidiary of Company, and each share of Company Common Stock that is owned 
by Parent, Newco or any other Subsidiary of Parent shall automatically be 
canceled and retired and shall cease to exist, and no cash or other 
consideration shall be delivered or deliverable in exchange therefor.

         (c) Merger Consideration.  Except as otherwise provided herein, each 
issued and outstanding share of Company Common Stock (other than shares 
canceled pursuant to Section 3.01(b) and Dissenting Shares (as defined in 
Section 3.01(d)) shall be converted into the right to receive in cash from 
Company following the Merger an amount equal to the highest price per share 
paid pursuant to the Offer, without interest (the "Merger Consideration").

         (d) Dissenting Shares.  Notwithstanding anything in this Agreement 
to the contrary, shares of Company Common Stock issued and outstanding 
immediately prior to the Effective Time held by a holder (if any) who has the 
right to demand payment for and an appraisal of such shares in accordance 
with Section 262 of the DGCL (or any successor provision) ("Dissenting 
Shares") shall not be converted into a right to receive Merger Consideration 
(but shall have the rights set forth in Section 262 of the DGCL (or any 
successor provision)) unless such holder fails to perfect or otherwise loses 
such holder's right to such payment or appraisal, if any.  If, after the 
Effective Time, such holder fails to perfect or loses any such right to 
appraisal, each such share of such holder shall be treated as a share that 
had been converted as of the Effective Time into the right to receive Merger 
Consideration in accordance with this Section 3.01.  Company shall give 
prompt notice to Parent of any demands received by Company for appraisal of 
shares of Company Common Stock, and Parent shall have the right to 
participate in and approve all negotiations and proceedings with respect to 
such demands.  Company shall not, except with the prior written consent of 
Parent, make any payment with respect to, or settle or offer to settle, any 
such demands.

         (e) Cancellation and Retirement of Company Common Stock.  As of the 
Effective Time, all shares of Company Common Stock (other than shares 
referred to in Section 3.01(d)) issued and outstanding immediately prior to 
the Effective Time, shall no longer be outstanding and shall automatically be 
canceled and retired and shall cease to exist, and each holder of a 
certificate representing any such shares of Company Common Stock shall, to 
the extent such certificate represents such shares, cease to have any rights 
with respect thereto, 

                                         -7-


<PAGE>


except the right to receive the Merger Consideration, to be paid in 
consideration therefor upon surrender of such certificate in accordance with 
Section 3.03.

         SECTION 3.02.  Treatment of Options. (a)  Except as otherwise 
agreed to in writing between Company and the holder of any Company Stock 
Option (as defined below), and as consented to by Parent, immediately prior 
to the Effective Time, each outstanding stock option to purchase shares of 
Company Common Stock held by a current or former employee or director of 
Company or any Subsidiary thereof (a "Company Stock Option") granted under 
any stock option or stock purchase plan, program or arrangement of Company, 
including without limitation, the Management Incentive Stock Plan and the 
1996 Management Incentive Stock Plan (collectively, the "Stock Plans"), 
whether or not then exercisable, shall be canceled by Company, and at the 
Effective Time or as soon as practicable thereafter, the holder thereof shall 
be entitled to receive from Company as of or as soon as practicable after the 
Effective Time in consideration for such cancellation an amount in cash equal 
to the product of (i) the number of shares of Company Common Stock previously 
subject to such Company Stock Option and (ii) the excess, if any, of the 
Merger Consideration over the exercise price per share, previously specified 
in such Company Stock Option, reduced by the amount of withholding or other 
taxes required by law to be withheld.

         (b) Except as provided herein or as otherwise agreed by the parties, 
the Stock Plans and any other plan, program or arrangement providing for the 
issuance or grant of any other interest in respect of the capital stock of 
Company shall terminate as of the Effective Time.

         (c) Prior to the Effective Time, the Board of Directors (or, if 
appropriate, any committee administering the Stock Plans) shall adopt such 
resolutions or take such actions as are necessary, subject if necessary, to 
obtaining consents of the holders thereof, to carry out the terms of this 
Section 3.02.

         SECTION 3.03.  Exchange of Certificates. (a)  Exchange Agent.  
Prior to the earlier to occur of (i) the mailing of the Proxy Statement (as 
defined in Section 4.01(d)) or (ii) the Effective Time, Parent shall appoint 
a bank or trust company located in the United States which is reasonably 
satisfactory to Company to act as exchange agent (the "Exchange Agent") for 
the payment of the Merger Consideration.  As of or as soon as reasonably 
practicable after the Effective Time, Parent or Newco shall cause Company to 
deposit with the Exchange Agent, for the benefit of the holders of shares of 
Company Common Stock, for exchange in accordance with this Article III, cash 
in an amount equal to the aggregate Merger Consideration to be paid hereunder 
(the "Exchange Fund").

         (b) Exchange Procedures.  As soon as practicable after the Effective 
Time, each holder of an outstanding certificate or certificates which prior 
thereto represented shares of Company Common Stock shall, upon surrender to 
the Exchange Agent of such certificate or certificates and acceptance thereof 
by the Exchange Agent, be entitled to the amount of cash, into which the 
number of shares of Company Common Stock previously represented by such 
certificate or certificates surrendered shall have been converted pursuant to 
this Agreement. 

                                         -8-

The Exchange Agent shall accept such certificates upon compliance with such 
reasonable terms and conditions as the Exchange Agent may impose to effect an 
orderly exchange thereof in accordance with normal exchange practices.  After 
the Effective Time, there shall be no further transfer on the records of 
Company or its transfer agent of certificates representing shares of Company 
Common Stock and if such certificates are presented to Company for transfer, 
they shall be canceled against delivery of the Merger Consideration.  If any 
Merger Consideration is to be remitted to a name other than that in which the 
certificate for Company Common Stock surrendered for exchange is registered, 
it shall be a condition of such exchange that the certificate so surrendered 
shall be properly endorsed, with signature guaranteed, or otherwise in proper 
form for transfer and that the Person (as defined in Section 9.04) requesting 
such exchange shall pay to Company or its transfer agent any transfer or 
other taxes required by reason of the payment of Merger Consideration to a 
name other than that of the registered holder of the certificate surrendered, 
or establish to the satisfaction of Company or its transfer agent that such 
tax has been paid or is not applicable.  Until surrendered as contemplated by 
this Section 3.03(b), each certificate for shares of Company Common Stock 
shall be deemed at any time after the Effective Time to represent only the 
right to receive upon such surrender the Merger Consideration as contemplated 
by Section 3.01.  No interest will be paid or will accrue on any amount 
payable as Merger Consideration.

         (c) No Further Ownership Rights in Company Common Stock.  Merger 
Consideration paid upon the surrender for exchange of certificates 
representing shares of Company Common Stock in accordance with the terms of 
this Article III shall be deemed to have been paid in full satisfaction of 
all rights pertaining to the shares of Company Common Stock represented by 
such certificates.

         (d) Termination of Exchange Fund.  Any portion of the Exchange Fund 
(including any interest and other income received by the Exchange Agent in 
respect of all such funds) which remains undistributed to the holders of the 
certificates representing shares of Company Common Stock for six months after 
the Effective Time shall be delivered to Company, upon demand, and any 
holders of shares of Company Common Stock prior to the Merger who have not 
theretofore complied with this Article III shall thereafter look only to 
Company and only as general creditors thereof for payment of their claim for 
Merger Consideration to which such holders may be entitled.

         (e) No Liability.  No party to this Agreement shall be liable to any 
Person in respect of any amount from the Exchange Fund delivered to a public 
official pursuant to any applicable abandoned property, escheat or similar 
law. If any certificates representing shares of Company Common Stock shall 
not have been surrendered in exchange for Merger Consideration prior to one 
year after the Effective Time (or immediately prior to such earlier date on 
which any Merger Consideration would otherwise escheat to or become the 
property of any Governmental Entity (as defined in Section 4.01(d))), any 
such amount shall, to the extent permitted by applicable law, become the 
property of Company, free and clear of all claims or interest of any Person 
previously entitled thereto.

         (f) Investment of Exchange Fund.  The Exchange Agent shall invest

such investment shall be (i) securities issued or directly and fully 
guaranteed or insured by the United States government or any agency or 
instrumentality thereof having maturities of not more than six months from 
the Effective Time, (ii) certificates of deposit, eurodollar time deposits 
and bankers' acceptances with maturities not exceeding six months and 
overnight bank deposits with any commercial bank, depository institution or 
trust company incorporated or doing business under the laws of the United 
States of America, any state thereof or the District of Columbia, provided 
that such commercial bank, depository institution or trust company has, at 
the time of investment, (A) capital and surplus exceeding $250 million and 
(B) outstanding short-term debt securities which are rated at least A-1 by 
Standard & Poor's Rating Group Division of The McGraw-Hill Companies, Inc. or 
at least P-1 by Moody's Investors Services, Inc. or carry an equivalent 
rating by a nationally recognized rating agency if both of the two named 
rating agencies cease to publish ratings of investment, (iii) repurchase 
obligations with a term of not more than 30 days for underlying securities of 
the types described in clauses (i) and (ii) above entered into with any 
financial institution meeting the qualifications specified in clause (ii) 
above, (iv) commercial paper having a rating in the highest rating categories 
from Standard & Poor's Rating Group Division of The McGraw-Hill Companies,

a nationally recognized rating agency if both of the two named rating 
agencies cease to publish ratings of investments and in each case maturing 
within six months of the Effective Time and (v) money market mutual or 
similar funds having assets in excess of $1 billion.  Any interest and other 
income resulting from such investments shall be paid to Company.

         (g) Lost Certificates.  In the event any certificate or certificates 
representing shares of Company Common Stock shall have been lost, stolen or 
destroyed, upon the making of an affidavit of that fact by the Person 
claiming such certificate or certificates to be lost, stolen or destroyed, 
the Exchange Agent will issue in exchange for such lost, stolen or destroyed 
certificate the Merger Consideration deliverable in respect thereof as 
determined in accordance with, this Article III, provided that the Person to 
whom the Merger Consideration is paid shall, if requested by the Surviving 
Corporation and as a condition precedent to the payment thereof, give the 
Surviving Corporation a bond in such reasonable amount as it may direct or 
otherwise indemnify the Surviving Corporation in a manner satisfactory to it 
against any claim that may be made against the Surviving Corporation with 
respect to the certificate claimed to have been lost, stolen or destroyed.

power and authority to carry on its business as now being conducted.  Company 
is duly qualified or licensed to do business and is in good standing in each 
jurisdiction in which the nature of its business or the ownership or leasing 
of its properties makes such qualification or licensing necessary, other than 
in such jurisdictions where the failure to be so qualified or licensed 
(individually or in the aggregate) would not have a Material Adverse Effect 
(as defined in Section 9.04) with respect to Company.  Prior to the date 
hereof, Company has delivered to Parent complete and correct copies of the 
Certificate of Incorporation and By-laws of Company as currently in effect.

         (b) Subsidiaries; Investments.  The only direct or indirect 
Subsidiary of Company is Prime Equipment Company, a Texas corporation, which

indirectly, any capital stock or other ownership interest in any other 
corporation, partnership, business association, joint venture or other entity.

         (c) Capital Structure.  The authorized capital stock of Company 
consists of (i) 100,000,000 shares of Company Common Stock, par value $.01

outstanding (excluding shares held in the treasury of Company); (ii) no

4.01(c) of the disclosure schedule delivered to Parent by Company at the time 
of execution of this Agreement (the "Disclosure Schedule"); and (v) no shares 
of Preferred Stock issued and outstanding or in the treasury of Company.  
Except as set forth above, no shares of capital stock or other equity 
securities of Company are issued, reserved for issuance or outstanding. All 
outstanding shares of capital stock of Company are, and all shares which may 
be issued pursuant to the Stock Plans will be, when issued, duly authorized, 
validly issued, fully paid and nonassessable and not subject to preemptive 
rights.  There are no outstanding bonds, debentures, notes or other 
indebtedness or other securities of Company having the right to vote (or

on any matters on which stockholders of Company may vote.  Except as set 
forth above, there are no outstanding securities, options, warrants, calls, 
rights, commitments, agreements, arrangements or undertakings of any kind to

make any payment in respect of any shares of capital stock of Company and, 
except as contemplated by the Stockholder Agreement, to the knowledge (as 
defined in Section 9.04) of Company, there are no irrevocable proxies with 
respect to shares of capital stock of Company.  Except as set forth in 
Section 4.01(c) of the Disclosure Schedule, there are no agreements or 
arrangements pursuant to which Company is or could be required to register 
shares of Company Common Stock or other securities under the Securities Act 
of 1933, as amended (the "Securities Act") or other agreements or

         (d) Authority; Noncontravention.  Company has the requisite 
corporate power and authority to enter into this Agreement and, subject to 
Company Stockholder Approval (as defined in Section 4.01(q)) with respect to

hereby. The execution and delivery of this Agreement by Company and the 
consummation by Company of the transactions contemplated hereby have been 
duly authorized by all necessary corporate action on the part of Company, 
subject, in the case of the Merger, to Company Stockholder Approval.  This 
Agreement has been duly executed and delivered by Company and (assuming due

accordance with its terms, except that (i) such enforcement may be subject to 
applicable bankruptcy, insolvency or similar laws, now or hereafter in 
effect, affecting creditors' rights generally, and (ii) the remedy of 
specific performance and injunctive and other forms of equitable relief may 
be subject to equitable defenses and to the discretion of the court before 
which any proceeding therefor may be brought.  Except as disclosed in Section 
4.01 of the Disclosure Schedule, the execution and delivery of this Agreement 
does not, and the consummation by Company of the transactions contemplated by 
this Agreement and compliance by Company with the provisions hereof will not, 
conflict with, or result in any breach or violation of, or default (with or 
without notice or lapse of time, or both) under, or give rise to a right of 
termination, cancellation or acceleration of or "put" right with respect to 
any obligation or to loss of a material benefit under, or result in the 
creation of any Lien (as defined in Section 9.04) upon any of the properties 
or assets of Company under, (i) the Certificate of Incorporation, as amended, 
or By-laws, as amended, of Company, (ii) any loan or credit agreement, note, 
note purchase agreement, bond, mortgage, indenture, lease or other agreement,

other matters referred to in the following sentence, any judgment, order, 
decree, statute, law, ordinance, rule, regulation or arbitration award

rights, losses or Liens that individually or in the aggregate would not have 
a Material Adverse Effect with respect to Company or could not prevent, 
materially hinder or materially delay the ability of Company to consummate 
the transactions contemplated by this Agreement.  No consent, approval, order 
or authorization of, or registration, declaration or filing with, or notice 
to, any federal, state or local government or any court, administrative

Company.

         (e) SEC Documents.  Company has filed with the SEC all reports, 
schedules, forms, statements and other documents required pursuant to the 
Securities Act and the Exchange Act since February 27, 1995 (collectively,

respective dates, the SEC Documents complied in all material respects with

be, and the rules and regulations of the SEC promulgated thereunder 
applicable to such SEC Documents, and none of the SEC Documents (including 
any and all financial statements included therein) as of such dates contained

to normal year-end audit adjustments).

         (f) Information Supplied.  None of the information supplied or to be 
supplied by Company for inclusion or incorporation by reference in (i) the

and the rules and regulations promulgated thereunder, except that no 
representation is made by Company with respect to statements made or 
incorporated by reference therein based on information supplied in writing by

Agreement, the parties agree that statements made and information in the 
Schedule 14D-9 and the Proxy Statement relating to the federal income tax 
consequences of the transactions herein contemplated to holders of Company 
Common Stock shall be deemed to be supplied by Company and not by Parent or

foreign jurisdiction), as of the Effective Time, except as disclosed in 
Section 4.01(i) of the Disclosure Schedule, the assets of each such Company 
Plan are at least equal in value to the present value of the accrued benefits

                                Additional Agreements

         SECTION 6.01.  Proxy Statement; Stockholder Meeting.

         (a) Company and each of Parent and Newco shall prepare and file, or 
shall cause to be prepared and filed, with  the SEC those documents, 
schedules and amendments and supplements thereto required to be filed with 
respect to the transactions contemplated by this 

                                         -29-


<PAGE>


Agreement.  Company, acting through its Board of Directors, shall, if 
necessary, cause a meeting of its stockholders (the "Stockholders Meeting") 
to be duly called (including establishing the record date, if requested, to 
be the date immediately after the date Newco first purchases any shares of 
Company Common Stock pursuant to the Offer) and shall give notice of, convene 
and hold the Stockholders Meeting as soon as practicable, and at such time 
and place designated by Parent, for the purpose of approving the Merger, this 
Agreement and any other actions contemplated hereby which required the 
approval of Company's stockholders.  Company shall recommend to its 
stockholders approval of the Merger and take all reasonable actions necessary 
to solicit such approval. Company shall use its best efforts to obtain and 
furnish the information required to be included by it in the Proxy Statement 
and, after consultation with Parent, shall respond promptly to any comments 
of the SEC relating to any preliminary proxy statement regarding the Merger 
and the other transactions contemplated by this Agreement and to cause the 
Proxy Statement to be mailed to its stockholders, all at the earliest 
practicable time.  Whenever any event occurs which should be set forth in an 
amendment or supplement to the Proxy Statement or any other filing required 
to be made with the SEC with respect to the Proxy Statement or the 
Stockholders Meeting, each party shall promptly inform the other of such 
occurrence and cooperate in filing with the SEC and/or mailing to Company's 
stockholders such amendment or supplement.  The Proxy Statement and all 
amendments and supplements thereto shall comply with applicable law and be in 
form and substance satisfactory to each of Parent and Company.  Company, 
acting through its Board of Directors, shall include in the Proxy Statement 
the recommendation of its Board of Directors that stockholders of Company 
vote in favor of the approval and adoption of this Agreement and the Merger.  
Company shall use its best efforts to solicit from stockholders of Company 
proxies in favor of such approval and adoption and shall take all other 
actions necessary or, in the reasonable judgment of Parent, advisable to 
secure the vote or consent of the Company's stockholders required by the DGCL 
to effect the Merger.

         (b) Notwithstanding anything to the contrary contained herein, in 
the event that Newco shall acquire at least ninety percent (90%) of the 
outstanding Shares, the parties hereto agree, at the request of Parent, 
subject to Article VII, to take all necessary and appropriate action to cause 
the Merger to become effective as soon as reasonably practicable after such 
acquisition, without a meeting and without a vote of the Company's 
stockholders, in accordance with the DGCL.

         SECTION 6.02.  Access to Information; Confidentiality.  (a) Company 
shall, and shall cause its officers, employees, counsel, financial advisors 
and other representatives to, afford to Parent and its representatives and to 
potential financing sources reasonable access during normal business hours, 
in a manner initially coordinated with the chief executive officer of 
Company, and thereafter coordinated with those persons designated by the 
chief executive officer, during the period prior to the Effective Time to its 
properties, books, contracts, commitments, personnel and records, including 
security position listings and other information concerning beneficial owners 
and/or record owners of Company's securities which may be relevant to the 
Merger or Offer, and, during such period, 

                                         -30-


<PAGE>


Company shall, and shall cause its officers, employees and representatives 
to, furnish promptly to Parent (i) a copy of each report, schedule, 
registration statement and other document filed by it during such period 
pursuant to the requirements of federal or state securities laws and (ii) all 
other information concerning its business, properties, financial condition, 
operations and personnel as Parent may from time to time reasonably request.  
Each of Company, Parent and Newco will hold, and will cause its respective 
directors, officers, employees, accountants, counsel, financial advisors and 
other representatives and Affiliates to hold, any nonpublic information in 
confidence to the extent required by, and in accordance with, the provisions 
of the letter dated May 6, 1997, between Atlas Copco AB, Company and 
Investcorp International, Inc. (the "Confidentiality Agreement").

         (b) No investigation pursuant to this Section 6.02 shall affect any 
representations or warranties of the parties herein or the conditions to the 
obligations of the parties hereto.

         SECTION 6.03.  Reasonable Best Efforts.  Upon the terms and subject 
to the conditions set forth in this Agreement, each of the parties agrees to 
use its reasonable best efforts to take, or cause to be taken, all actions, 
and to do, or cause to be done, and to assist and cooperate with the other 
parties in doing, all things necessary, proper or advisable under applicable 
laws and regulations to consummate and make effective, in the most 
expeditious manner practicable, the Merger and the other transactions 
contemplated by this Agreement, including the Offer.  Parent and Company will 
use their reasonable best efforts and cooperate with one another (i) in 
promptly determining whether any filings are required to be made or consents, 
approvals, waivers, licenses, permits or authorizations are required to be 
obtained (or, which if not obtained, would result in an event of default, 
termination or acceleration of any agreement or any put right under any 
agreement) under any applicable law or regulation or from any Governmental 
Entities or third parties, including parties to loan agreements or other debt 
instruments, in connection with the transactions contemplated by this 
Agreement, including the Merger and the Offer and (ii) in promptly making any 
such filings, in furnishing information required in connection therewith and 
in timely seeking to obtain any such consents, approvals, permits or 
authorizations.

         SECTION 6.04.  Indemnification. (a)  The certificate of 
incorporation and the by-laws of the Surviving Corporation shall contain the 
provisions with respect to indemnification and exculpation from liability set 
forth in Company's certificate of incorporation and by-laws on the date of 
this Agreement, 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 adversely affect the rights thereunder of individuals who on or prior 
to the Effective Time were directors, officers, employees or agents of 
Company, unless such modification is required by law.

         (b) Company shall maintain in effect for three years from the 
Effective Time policies of directors' and officers' liability insurance 
containing terms and conditions which are not less advantageous to the 
insureds than any such policies currently in effect on the date of this 
Agreement (the "Company Insurance"), with respect to matters occurring prior 
to the Effective Time, to the extent available, and having the maximum 
available coverage under any 

                                         -31-


<PAGE>


such Company Insurance policies; provided that (i) Company following the 
Merger shall not be required to spend in excess of 150% of the amount spent 
on current annual premiums for the Company Insurance (the "Premium Limit") 
per year therefor; provided further that if Company following the Merger 
would be required to spend in excess of the Premium Limit per year to obtain 
insurance having the maximum available coverage under Company Insurance 
policies, Company will be required to spend up to such amount to maintain or 
procure insurance coverage pursuant hereto, subject to availability of such 
(or similar) coverage and (ii) such policies may in the sole discretion of 
Company be one or more "tail" policies for all or any portion of the full 
three year period, provided that such "tail" policies, contain terms and 
conditions and provide coverage no less advantageous to the insureds than the 
terms, conditions and coverage in the Company Insurance.  Company agrees that 
in the event it would be required to spend in excess of the Premium Limit per 
year to obtain insurance having the maximum available coverage under Company 
Insurance policies, Company will notify the officers and directors who are 
the beneficiaries thereof and permit such officers and directors to pay any 
excess amount over the Premium Limit which may be necessary to maintain such 
policies.

         (c) From and after the purchase of any shares of Company Common 
Stock pursuant to the Offer, Parent agrees to indemnify and agrees to cause 
the Surviving Corporation to indemnify all persons who are covered on the 
date of this Agreement by the Company Insurance (the "Indemnified Parties") 
to the fullest extent permitted by applicable law with respect to all acts 
and omissions arising out of such individuals' services as officers, 
directors, employees or agents of Company or as trustees or fiduciaries of 
any plan for the benefit of employees of Company, occurring prior to the 
Effective Time including, without limitation, the transactions contemplated 
by this Agreement. Without limitation of the foregoing, in the event any such 
Indemnified Party is or becomes involved in any capacity in any action, 
proceeding or investigation in connection with any matter, including without 
limitation, the transactions contemplated by this Agreement, occurring prior 
to, and including, the Effective Time, Parent, from and after the date of 
purchase of any shares of Company Common Stock pursuant to the Offer, will 
pay as incurred such Indemnified Party's reasonable legal and other expenses 
(including the cost of any investigation and preparation) incurred in 
connection therewith.  Subject to Section 6.04(d), Parent shall advance (in 
reasonable amounts) and pay all reasonable expenses, including attorneys' 
fees, that may be incurred by any Indemnified Party in enforcing this Section 
6.04 or any action involving an Indemnified Party resulting from the 
transactions contemplated by this Agreement.  Notwithstanding anything to the 
contrary contained herein, Parent shall not have any obligation hereunder to 
any Indemnified Party when and if a court of competent jurisdiction shall 
ultimately determine, and such determination shall have become final, that 
the indemnification of such Indemnified Party in the manner contemplated 
hereby is prohibited by applicable law.

         (d) Any Indemnified Party wishing to claim indemnification under 
this Section 6.04, upon learning of any claim, action, suit, proceeding or 
investigation which may give rise to a right to indemnification under this 
Section 6.04, shall promptly notify Parent thereof.  In the event of any such 
claim, action, suit, proceeding or investigation, (i) Parent or the Surviving 
Corporation shall have the right to assume the defense thereof (with counsel

                                         -32-


<PAGE>


engaged by Parent or the Surviving Corporation to be reasonably acceptable to 
the Indemnified Party) and, provided there is no conflict of interest, Parent 
shall not be liable to such Indemnified Party for any legal expenses of other 
counsel or any other expenses subsequently incurred by such Indemnified Party 
in connection with the defense thereof, (ii) the Indemnified Party will 
cooperate in the defense of any such matter and (iii) Parent shall not be 
liable for any settlement effected without its prior written consent.

         SECTION 6.05.  Public Announcements.  Neither Parent or Newco, on 
the one hand, nor Company, on the other hand, will issue any press release or 
public statement with respect to the transactions contemplated by this 
Agreement, including the Merger and the Offer, without the other party's 
prior consent (such consent not to be unreasonably withheld), except as may 
be required by applicable law, court process or by obligations pursuant to 
any listing agreement with the New York Stock Exchange.  In addition to the 
foregoing, Parent and Company will consult with each other before issuing, 
and provide each other the opportunity to review and comment upon, any such 
press release or other public statements with respect to such transactions.  
The parties agree that the initial press release or releases to be issued 
with respect to the transactions contemplated by this Agreement shall be 
mutually agreed prior to the issuance thereof.

         SECTION 6.06.  Employee Benefits. (a)  Parent agrees that, and 
shall take all necessary action to ensure that, during the period commencing 
at the Effective Time and ending on the first anniversary thereof, the 
employees of Company will continue to be provided with (whether by Parent, 
the Surviving Corporation or otherwise) employee benefit plans (other than 
stock option or other plans involving the potential issuance of securities of 
Company) which in the aggregate are not materially less favorable to those 
currently provided by Company to such employees, to the extent permitted 
under laws and regulations in force from time to time, provided, however, 
that subject to compliance with this Section 6.06, Parent reserves the right 
to review all employee benefits after the Effective Time and to make such 
changes as it deems appropriate.

         (b) If any salaried employee of Company becomes a participant in any 
employee benefit plan, practice or policy of the Parent (or any of its 
Subsidiaries), such employee shall be given credit under such plan, practice 
or policy for all service prior to the Effective Time with Company or any 
predecessor employer (to the extent such credit was given by Company), and 
all service after the Effective Time and prior to the time such employee 
becomes such a participant, for purposes of eligibility and vesting and for 
all other purposes for which such service is either taken into account or 
recognized; provided, however, such service need not be credited to the 
extent it would result in a violation of the terms of Parent's defined 
benefit plans or result in a duplication of benefits, including, without 
limitation, benefit accrual service under defined benefit plans.

         SECTION 6.07.  No Solicitation.  Company shall not (whether 
directly or indirectly through advisors, agents or other intermediaries), nor 
shall Company authorize or permit any of its officers, directors, agents, 
representatives, advisors to (a) solicit, initiate or 

                                         -33-


<PAGE>


take any action knowingly to facilitate the submission of inquiries, 
proposals or offers from any Person (other than Newco or Parent) relating to 
(i) any acquisition or purchase of 20% or more of the consolidated assets of 
Company or of over 20% of any class of equity securities of Company, (ii) any 
tender offer (including a self tender offer) or exchange offer that if 
consummated would result in any Third Party (as defined in Section 9.02) 
beneficially owning 20% or more of any class of equity securities of Company, 
(iii) any merger, consolidation, business combination, sale of substantially 
all assets, recapitalization, liquidation, dissolution or similar transaction 
involving Company other than the transactions contemplated by this Agreement, 
or (iv) any other transaction the consummation of which would or could 
reasonably be expected to impede, interfere with, prevent or materially delay 
the Merger or the Offer or which would or could reasonably be expected to 
materially dilute the benefits to Parent of the transactions contemplated 
hereby (collectively, "Transaction Proposals"), (b) agree to or endorse any 
Transaction Proposal, or (c) enter into or participate in any discussions or 
negotiations regarding any of the foregoing, or furnish to any other Person 
any information with respect to its business, properties or assets or any of 
the foregoing, or otherwise cooperate in any way with, or knowingly assist or 
participate in, facilitate or encourage, any effort or attempt by any other 
Person (other than Newco or Parent) to do or seek any of the foregoing; 
provided, however, that nothing in this Agreement shall prohibit Company 
(either directly or indirectly through advisors, agents or other 
intermediaries) from (A) furnishing information pursuant to an appropriate 
confidentiality letter (which letter shall not be less favorable to Company 
in any material respect than the Confidentiality Agreement, concerning 
Company and its business, properties or assets to a third party who has 
offered to make a bona fide Transaction Proposal, (B) engaging in discussions 
or negotiations with such third party (C) following receipt of a bona fide 
Transaction Proposal, taking and disclosing to its stockholders a position 
contemplated by Rule 14e-2(a) under the Exchange Act or otherwise making 
disclosure to its stockholders, (D) following receipt of a bona fide 
Transaction Proposal, failing to make or withdrawing or modifying its 
recommendation referred to in Section 4.01(p), and/or (E) taking any 
non-appealable, final action ordered to be taken by Company by any court of 
competent jurisdiction but in each case referred to in the foregoing clauses 
(A) through (D) only to the extent that the Board of Directors of Company 
shall have concluded in good faith after consulting with its outside counsel 
and financial advisors that such action is consistent with the discharge of 
its fiduciary duties to the stockholders of Company under applicable law; 
provided, further, that the Board of Directors of Company shall not take any 
of the foregoing actions referred to in clauses (A) through (E) above, until 
after reasonable notice to Parent with respect to such action and that such 
Board of Directors shall, to the extent it may do so without breaching such 
fiduciary duties, continue to advise Parent after taking such action and, in 
addition, if the Board of Directors of Company receives a Transaction 
Proposal, then Company shall promptly inform Parent of the terms and 
conditions of such proposal and the identity of the Person making it.  
Company will immediately cease and cause its advisors, agents and other 
intermediaries to cease any and all existing activities, discussions or 
negotiations with any parties conducted heretofore with respect to any of the 
foregoing, and shall use its reasonable best efforts to cause any such 
parties in possession of confidential information about Company that was 
furnished by or on behalf of Company to return or destroy all such 
information in the possession of any such party or in the possession of any 
agent or advisor of any such party.

shall deliver to Parent evidence satisfactory to Parent of the resignation of 
all Continuing Directors, effective at the Effective Time.

                                     ARTICLE VII.

                                 Conditions Precedent

         SECTION 7.01.  Conditions to Each Party's Obligation To Effect the 
Merger.  The respective obligation of each party to effect the Merger is

following conditions:

         (a) Company Stockholder Approval.  To the extent required by 
applicable law, Company Stockholder Approval shall have been obtained.

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

         (c) No Injunctions or Restraints.  No temporary restraining order, 
preliminary or permanent injunction or other order issued by any court of 
competent jurisdiction or other legal restraint or prohibition preventing the 
consummation of the Merger shall be in effect; provided, however, that the 
parties hereto shall use their best efforts to have any such injunction, 
order, restraint or prohibition vacated.

         SECTION 7.02.  Conditions to Obligations of Parent and Newco.  The 
obligations of Parent and Newco to effect the Merger are further subject to 
the following conditions:

         (a) Representations and Warranties.  The representations and 
warranties of Company set forth in this Agreement shall be true and correct 
in each case as of the date of this Agreement and (except to the extent such

Date as though made on and as of the Closing Date, except where the failure 
of such representations and warranties to be so true and correct (without 
giving effect to any limitation as to "materiality" or "Material Adverse 
Effect" set forth therein) would not individually or in the aggregate have a 
Material Adverse Effect.  Parent 

                                         -35-


<PAGE>


shall have received a certificate signed on behalf of Company by the chief 
executive officer and the chief financial officer of Company to the effect 
set forth in this paragraph.

         (b) Performance of Obligations of Company.  Company shall have 
performed the obligations required to be performed by it under this Agreement 
at or prior to the Closing Date (except for such failures to perform either 
individually or in the aggregate that would not have a Material Adverse 
Effect with respect to Company or materially adversely affect the ability of 
Company to consummate the transactions herein contemplated or perform its 
obligations hereunder).

         (c) Consents, etc.  Parent shall have received evidence, in form and 
substance reasonably satisfactory to it, that such licenses, permits, 
consents, approvals, authorizations, qualifications and orders of 
governmental authorities and other third parties as are necessary in 
connection with the transactions contemplated hereby have been obtained, 
except where the failure to obtain such licenses, permits, consents, 
approvals, authorizations, qualifications and orders individually or in the 
aggregate would not have a Material Adverse Effect with respect to Company.

         (d) No Litigation.  There shall not be pending any suit, action or 
proceeding by any Governmental Entity or by any other Person, which has a 
reasonable likelihood of success and which, if successful, would have a 
Material Adverse Effect with respect to Company or Parent, or materially 
adversely affect the ability of the parties hereto to consummate the 
transactions contemplated herein.

Notwithstanding the foregoing, the obligations of Parent and Newco to effect 
the merger shall not be relieved by the failure of any of the foregoing 
conditions if such failure is the result, direct or indirect, of any breach 
by Parent or Newco of any of their obligations under this Agreement.

of Company to effect the Merger is further subject to the following 
conditions:

correct, in each case as of the date of this Agreement and (except to the 
extent such representations and warranties speak as of an earlier date) as of 
the Closing Date as though made on and as of the Closing Date, except where 
the failure of such representations and warranties to be so true and correct 
(without giving effect to any limitation as to "materiality" or "material 
adverse effect" set forth therein) would not individually or in the aggregate 
have a Material Adverse Effect with respect to Parent and Newco.  Company 
shall have received a certificate signed on behalf of Parent by an authorized 
officer of Parent to the effect set forth in this paragraph.

         (b) Performance of Obligations of Parent and Newco.  Parent and 
Newco shall have performed the obligations required to be performed by it 
under this Agreement at or prior to the Closing Date (except for such 
failures to perform, either individually or in the

                                         -36-

aggregate, that would not have a Material Adverse Effect with respect to 
Parent and Newco or materially adversely affect the ability of Parent and 
Newco to consummate the transactions herein contemplated or perform their 
respective obligations hereunder).

Notwithstanding the foregoing, the obligations of Company to effect the 
merger shall not be relieved by the failure of any of the foregoing 
conditions if such failure is the result, direct or indirect, of any breach 
by Company of any of its obligations under this Agreement.

                                    ARTICLE VIII.

approval of matters presented in connection with the Merger by the 
stockholders of Company:

         (a) by mutual written consent of Parent and Company; or

         (b) by either Parent or Company, if any Governmental Entity shall

    become final and nonappealable; or

         (c) by either Parent or Company, if the Merger shall not have been 
    consummated on or before October 31, 1997 (other than due to the failure 
    of the party seeking to terminate this Agreement to perform its 
    obligations under this Agreement required to be performed at or prior to 
    the Effective Time); or

         (d) if Company Stockholder Approval is required, by either Parent or 
    Company, if at the duly held meeting of the stockholders of Company 
    (including any adjournment thereof) held for the purpose of voting on the 
    Merger, this Agreement and the consummation of the transactions 
    contemplated hereby, the holders of a majority of the outstanding shares 
    of Company Common Stock shall not have approved the Merger, this 
    Agreement and the consummation of the transactions contemplated hereby; or

         (e) by Parent, if Company or its Board of Directors shall have (1) 
    withdrawn, modified or amended in any respect adverse to Parent its 
    approval or recommendation of this Agreement or any of the transactions 
    contemplated herein, (2) failed as promptly as practicable to mail the

    statement such recommendation in accordance with Section 6.01, (3)

         (f) by Company, if, pursuant to and in compliance with Section 6.07 
    hereof, the Board of Directors of Company does not make or withdraws or 
    modifies its recommendation referred to in Section 4.01(p).

         SECTION 8.02.  Effect of Termination.  In the event of termination 
of this Agreement by either Company or Parent as provided in Section 8.01, 
this Agreement shall forthwith become void and have no effect, without any 
liability or obligation on the part of Parent, Newco or Company, other than 
the provisions of Section 4.01(n), Section 4.02(e), the last sentence of 
Section 6.02(a), this Section 8.02, Section 9.02, Section 9.07 and 9.08. 
Nothing contained in this Section shall relieve any party of any liability 
for any breach of the representations, warranties, covenants or agreements 
set forth in this Agreement.

         SECTION 8.03.  Amendment.  This Agreement may be amended by the 
parties at any time before or after any required approval of matters 
presented in connection with the Merger by the stockholders of Company; 
provided, however, that after any such approval, there shall be made no 
amendment that by law requires further approval by such stockholders without 
the further approval of such stockholders.  This Agreement may not be amended 
except by an instrument in writing signed on behalf of each of the parties.

inaccuracies in the representations and warranties contained in this 
Agreement or in any document delivered pursuant to this Agreement or (c) 
subject to the proviso of Section 8.03, waive compliance with any of the 
agreements or conditions contained in this Agreement.  Any agreement on the 
part of a party to any such extension or waiver shall be valid only if set 
forth in an instrument in writing signed on behalf of such party.  The 
failure of any party to this Agreement to assert any of its rights under this 
Agreement or otherwise shall not constitute a waiver of such rights.

         SECTION 8.05.  Procedure for Termination, Amendment, Extension or 
Waiver.  A termination of this Agreement pursuant to Section 8.01, an 
amendment of this Agreement pursuant to Section 8.03 or an extension or 
waiver pursuant to Section 8.04 shall, in order to be effective, require in 
the case of Parent or Company, action by its Board of Directors or the duly 
authorized designee of its Board of Directors.

                                     ARTICLE IX.

the Merger and neither Company nor any officer, director or employee or 
stockholder shall be under any liability whatsoever with respect to any 

                                         -38-

transactions contemplated by this Agreement and the financing thereof; 
provided, that in no event shall Company be required to pay in excess of an

         (b) If this Agreement is terminated pursuant to Section 8.01(e) or 
Section 8.01(f) and within twelve months following the date of such

referred to in Section 13(d)(3) of the Exchange Act, and including Company

Affiliates (collectively, "Third Party") a transaction the proposal of which 
would otherwise qualify as a Transaction Proposal under Section 6.07 or (y) 
enters into a definitive agreement with a Third Party with respect to a 
transaction the proposal of which would otherwise qualify as a Transaction 
Proposal under Section 6.07 (whether or not such Third Party is the same 
Third Party referred to in clause (i) above), then Company shall promptly, 
but in no event later than one business day after Company consummates the 
transaction referred to in clause (x) or (y) above, pay to Parent, in same 
day funds, a fee of $27.2 million, less any amounts paid by Company pursuant

expenses, including, without limitation, the reasonable fees and 
disbursements of counsel and the expenses of litigation, incurred in 
connection with collecting the expenses pursuant to paragraph (a) of this 
Section and the fee pursuant to paragraph (b) of this Section, as a result of

submission of inquiries, proposals or offers from any Person (other than 
Parent or any of its affiliates) relating to any Transaction Proposal or (b) 
enter into or participate in any discussions or negotiations regarding any of 
the foregoing, or furnish to any other Person any information with respect to 
the business, properties or assets or any of the foregoing, or otherwise 
cooperate in any way with, or knowingly assist or participate in, facilitate 
or encourage, any effort or attempt by any other Person (other than Parent or 
any of its affiliates) to do or seek any of the foregoing; provided, however,

any International Shares, deposit any International Shares into a voting 
trust or enter into a voting agreement with respect to any International 
Shares; or (c) take any action that would make any representation or warranty 
of any International Investor contained herein untrue or incorrect or have

    5.   Third Party Business Combination; Remedy.

         (a)(i)  If the Merger Agreement is terminated in accordance with 
Section 8.01(e) or Section 8.01(f) of the Merger Agreement, and, upon or 
following any such termination, any International Investor receives from any 
Person (other than Parent, Newco or any of their affiliates) any cash or 
non-cash consideration in an amount greater than $32.00 per share (the "Third 
Party Consideration") in respect of all or any portion of the International 
Shares in connection with or following any public announcement of a Third 
Party Business Combination (as defined below) during the period commencing on 
the date hereof and ending twelve months from the date the Merger Agreement 
is terminated (provided that the contract or agreement relating to such Third 
Party Business Combination was entered into within six months after the 
Merger Agreement is terminated), then such International Investor shall 
within two (2) Business Days of receipt thereof pay to Parent or its designee 
an aggregate amount equal to one hundred percent (100%) of (A) the excess of 
(1) the Third Party Consideration up to and including $36.00 over (2) $32.00 
multiplied by (B) the number of International Shares with respect to which 
such Third Party Consideration was received, or

         (ii)  if any International Investor receives from Parent, Newco or 
any of their affiliates any cash or non-cash consideration pursuant to the 
Offer or otherwise in an amount greater than $32.00 per share (the "Alternate 
Consideration") in respect of all or any portion of the International Shares 
owned by it following any public announcement of a Third Party Business 
Combination (as defined below) during the period commencing on the date 
hereof and ending twelve months from the date of such public announcement, 
then such International Investor shall within two (2) Business Days of 
receipt thereof pay to Parent or its designee an aggregate amount equal to 
(A) one hundred percent (100%) of the excess of (1) the Alternate 
Consideration up to and including $34.00 over (2) $32.00; and (B) fifty 
percent (50%) of the excess, if any, of (1) the Alternate Consideration up to 
and including $36.00 over (2) $34.00; in each case multiplied by the number 
of International Shares with respect to which such Alternative Consideration 
was received; 

provided that, in each case, (x) if the consideration received by an 
International Investor shall be securities listed on a national securities 
exchange or traded on the NASDAQ National Market ("NASDAQ"), the per share 
value of such consideration shall be equal to the closing price per share 
listed on such national securities exchange or NASDAQ on the date such 
transaction is consummated and (y) if the consideration received by an 
International Investor shall be in a form other than such listed securities, 
the per share value shall be determined in good faith as of the date such 
transaction is consummated by Parent or its designee and such International 
Investor, or, if Parent or its designee and such International Investor 
cannot reach agreement, by a nationally-recognized investment banking firm 
reasonably acceptable to the parties.  The term "Third Party Business 
Combination" with respect to the Company means the occurrence of any of the 
following events:  (i) the Company or any subsidiary of the Company whose 
assets constitute twenty percent (20%) or more of the Company's consolidated 
assets is acquired by merger or otherwise by any person or group, other than 
Parent or any affiliate thereof (a "Third Party"); (ii) the Company or any 
subsidiary of the Company enters into an agreement with a Third Party which 
contemplates the acquisition of twenty percent (20%) or more of the total 
assets of the Company and its subsidiaries, taken 

                                         -7-


<PAGE>

as a whole; (iii) the Company, or any International Investor enters into a 
merger or other agreement with a Third Party which contemplates the 
acquisition of more than twenty percent (20%) of the outstanding shares of 
Company Common Stock; or (iv) a Third Party acquires more than twenty percent 
(20%) of the outstanding Company Common Stock.

         (b)  If, within one hundred eighty (180) days after the acquisition 
by Parent, Newco or any of their affiliates (the "Acquiring Company") of the 
International Shares for an amount greater than $32.00 per share (as 
contemplated by Section 5(a)(ii)), the Acquiring Company sells all or 
substantially all of the outstanding shares of capital stock or assets of the 
Company, then the Acquiring Company shall within two (2) Business Days of 
receipt thereof pay to each International Investor or its designees an amount 
equal to the excess of the sales proceeds received by the Acquiring Company 
in connection with such sale attributable to the percentage ownership 
interest in the Company represented by the International Shares purchased by 
the Acquiring Company from such International Investor over the aggregate 
price paid by the Acquiring Company to such International Investor for such

or to such other address as the person to whom notice is given may have 
previously furnished to the others in writing in the manner set forth above.

         10.4 Governing Law. This Agreement shall be governed by and 
construed in accordance with the laws of the State of Delaware, regardless of 
the laws that might otherwise govern under applicable principles of conflicts 
of laws thereof.

         10.5 Enforcement.  The parties agree that irreparable damage would 
occur in the event that any of the provisions of this Agreement were not 
performed in accordance with their specific terms or were otherwise breached. 
It is accordingly agreed that the parties shall be entitled to an injunction 
or injunctions to prevent breaches of this Agreement and to enforce 
specifically the terms and provisions of this Agreement.

         10.6 Counterparts.  This Agreement may be executed in two or more 
counterparts, each of which shall be deemed to be an original, but all of 
which shall constitute one and the same Agreement.

         10.7 Descriptive Headings.  The descriptive headings used herein are 
inserted for convenience of reference only and are not intended to be part of 
or to affect the meaning or interpretation of this Agreement.

         10.8 Severability.  Whenever possible, each provision or portion of 
any provision of this Agreement will be interpreted in such manner as to be 
effective and valid under applicable law but if any provision or portion of 
any provision of this Agreement is held to be invalid, illegal or 
unenforceable in any respect under any applicable law or rule in any 
jurisdiction, such invalidity, illegality or unenforceability will not affect 
any other provision or portion of any provision in such jurisdiction, and 
this Agreement will be reformed, construed and enforced in such jurisdiction 
as if such invalid, illegal or unenforceable provision or portion of any 
provision had never been contained herein.

         10.9 Definitions.  For purposes of this Agreement:

         (a)  "beneficially own" or "beneficial ownership" with respect to

arrangement or understanding, whether or not in writing.  Without duplicative 
counting of the same securities by the same holder, securities beneficially 
owned by a Person shall include securities Beneficially Owned by all other 
Persons with whom such Person would constitute a "group" as described in 
Section 13(d)(3) of the Exchange Act.

         (b)  "Person" shall mean an individual, corporation, limited 
liability company, partnership, joint venture, association, trust, 
unincorporated organization or other entity.

         (c)  In the event of a stock dividend or distribution, or any change 
in the Company Common Stock by reason of any stock dividend, split-up, 
recapitalization, combination, exchange of shares or the like, the term 
"International Shares" shall be deemed to refer to and include the 
International Shares as well as all such stock dividends and distributions 
and any shares into which or for which any or all of the International Shares 
may be changed or exchanged.

         10.10  Stockholder Capacity.  Notwithstanding anything herein to the 
contrary, no person who is a director, officer or employee of an 
International Investor who is, or becomes during the term hereof, a director 
of the Company makes any agreement or understanding herein in his or her 
capacity as such director, and the agreements set forth herein shall in no 
way restrict any director in the exercise of his or her fiduciary duties as a 
director of the Company.  Each International Investor has executed this 
Agreement solely in its capacity as the record and/or beneficial holder of 
International Shares.

Report of Independent Accountants

To the Board of Directors and Stockholders
of Atlas Copco North America Inc.:

We have audited the accompanying consolidated balance sheets of Atlas Copco
North America Inc. and subsidiaries as of December 31, 1996 and 1995, and the
related consolidated statements of operations and retained earnings, and cash
flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the consolidated financial position of Atlas
Copco North America Inc. and subsidiaries as of December 31, 1996 and 1995, and
the consolidated results of their operations and their cash flows for the years
then ended, in conformity with generally accepted accounting principles.

ATLAS COPCO NORTH AMERICA INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
FOR THE YEARS ENDED DECEMBER 31, 1996 AND 1995
(Amounts in thousands, except share information)

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Principles of Consolidation and Preparation - Atlas Copco North America
     Inc. (the "Company" or "ACNA") is owned by Atlas Copco AB ("ACAB") and
     Atlas Copco Airpower n.v. ("ACA"), a wholly owned subsidiary of ACAB. ACAB
     and ACA own 73.5% and 26.5% of the outstanding common shares of ACNA,
     respectively. In December, 1996, ACNA effected a recapitalization whereby
     12,788 shares of common stock were issued for 100% of the outstanding
     preferred stock of ACNA, eliminating the outstanding preferred stock. The
     preferred shares were issued to ACA in September, 1995, in connection with
     the acquisition of Esstar Inc., and had a liquidation preference to ACA of
     $130 million.

     The Company is engaged primarily in the manufacture, sale, and rental of a
     diversified line of equipment, geographically disbursed, principally in the
     United States. The accompanying consolidated financial statements include
     the accounts of the Company and its subsidiaries. All intercompany accounts
     and transactions have been eliminated in consolidation. Investments in less
     than majority owned subsidiaries and affiliates are accounted for by the
     equity method.

     Use of Estimates - The preparation of financial statements in conformity
     with generally accepted accounting principals ("GAAP") requires management
     to make estimates and use assumptions that affect certain reported amounts
     and disclosures; actual amounts may differ.

     Foreign Currency Transactions and Translations - The financial statements
     of the Company's foreign subsidiaries are translated into U.S. dollars in
     accordance with Statement of Financial Accounting Standards ("SFAS") No.
     52. Assets and liabilities of foreign subsidiaries are translated into U.S.
     dollars at year-end exchange rates. Sales and expense items are translated
     at the average exchange rates prevailing during the period. Resulting
     translation adjustments are included in stockholders' equity.

     Gains and losses arising from the settlement of foreign currency
     transactions and year-end valuation of foreign-denominated receivables and
     payables are included in cost of sales and other income/expense in the
     accompanying Consolidated Statements of Operations and Retained Earnings
     and amounted to a net loss of $3,831 and $1,324 and 1996 and 1995,
     respectively.

     Revenue Recognition - Revenue is generally recognized when title passes to
     the customer. Fulfillment of certain contracts can span several months;
     revenue on such contracts is primarily recognized on the completed contract
     basis. Revenue is recognized under the percentage-of-completion method for
     contracts relating to the manufacture of tunnel boring equipment. Such
     contracts require estimates to determine the appropriate cost and revenue
     recognition. Current estimates of costs and revenues under the percentage
     of completion method may be revised as additional information becomes
     available. Unearned interest related to conditional sales contracts
     (installment sales) is netted against accounts receivable and amortized to
     income over the contract period. Rental income arising from operating
     equipment leases is accrued using the straight-line method.

     Cash and Cash equivalents - The Company considers all highly liquid
     investments with a maturity of three months or less at the date of purchase
     to be cash equivalents.

     Inventory - Inventories are valued at the lower of cost or market. Cost is
     determined principally by the last-in, first out ("LIFO") method.

     Rental Fleet - The rental fleet, which consists primarily of compressors
     leased under operating leases, is stated at cost. Depreciation is computed
     using the straight-line method over the estimated useful lives of the
     related assets (three to twelve years). Depreciation expense aggregated
     $10,952 and $10,734 in


                                        7
<PAGE>

     1996 and 1995 respectively. Accumulated depreciation at December 31, 1996
     and 1995 aggregated $57,196 and $49,478 respectively. Maintenance and
     repairs are charged to operations as incurred. Expenditures which increase
     productive capacity or extend the life of the rental fleet equipment leased
     under operating leases are capitalized.

     Property, Plant and Equipment - Property, plant and equipment is stated at
     cost. Depreciation is computed using the straight-line method over the
     estimated useful lives of the related assets (three to forty years).
     Depreciation expense aggregated $20,698 and $13,098 in 1996 and 1995,
     respectively. Maintenance and repairs are charged to operations as
     incurred. Expenditures which increase productivity or extend the life of an
     asset are capitalized.

     Goodwill and other intangibles - Goodwill represents the excess of cost
     over the fair value of assets acquired and liabilities assumed related to
     acquisitions by the Company. Goodwill and other intangibles are being
     amortized, on a straight-line basis, over ten to forty years. Accumulated
     amortization aggregated $52,464 and $39,941 at December 31, 1996 and 1995,
     respectively.

     The recoverability of long term assets, including goodwill is evaluated
     based upon operating results and other changes in the business or business
     environment. Should operating results or changes in the business or
     business environment indicate potential impairment, the Company will
     evaluate whether impairment exists based upon expected future cash flows.

     Income Taxes - Income taxes are accounted for under SFAS No. 109,
     "Accounting for Income Taxes." Under SFAS No. 109 deferred income taxes
     reflect the tax consequences of differences between the financial reporting
     and tax bases of assets and liabilities. A valuation allowance is provided
     for deferred tax assets whose realization is not considered to be more
     likely than not. Adjustments to the deferred income tax valuation allowance
     are made periodically based on management's assessment of the
     recoverability of the related assets.

     Provisions for deferred income taxes are recorded to the extent of
     withholding taxes and incremental U.S. taxes, if any, that will arise from
     repatriation of dividends from those foreign subsidiaries where local
     earnings are not permanently reinvested.

     Research and Development Costs - Research and development costs are
     charged to expense in the period in which the costs are incurred and
     amounted to approximately $24,306 and $15,623 and 1996 and 1995,
     respectively.

     Relocation Charge - In the second quarter of 1996 the Company recorded a
     charge of $12,800 related to its decision to relocate its Chicago Pneumatic
     Tool Company ("CP") headquarters from Utica, New York, to a new facility in
     Rock Hill, South Carolina. The significant components of the charge
     recorded in 1996 included employee termination benefits - $9,200; asset
     write-offs - $2,400; and other - $1,200. Of the $12,800 charge recorded in
     the second quarter, approximately $1,800 has been paid through the end of
     the year, and as a result the Company has a current liability of $5,111 and
     a long term liability of $5,889 recorded at December 31, 1996, for the
     remainder of the charge to be incurred subsequent to 1996.

     Reclassifications - Certain prior year amounts have been reclassified to
     conform with the current year presentation.

2.   ACQUISITIONS AND DIVESTITURES

     On August 1, 1995, the Company acquired 100% of the outstanding shares of
     Esstar Inc. (Esstar), for $570.2 million. Esstar owns 100% of Amstar
     Corporation which owns 100% of Milwaukee Electric Tool Corporation (METCO)
     and Milrem, Inc. (Milrem). METCO is a manufacturer of electric tools,
     primarily for the professional contractor market. Milrem is a corporation
     that was formed in connection with a previous sale of a business by Esstar
     and exists solely for the purpose of completing an environmental
     remediation program in Connecticut. The acquisition was accounted for as a
     purchase, and the purchase price was assigned to the tangible and
     intangible assets acquired and


                                        8
<PAGE>

     liabilities assumed based on the fair market values at the date of the
     acquisition. The purchase price exceeded the amounts assigned to such net
     assets by approximately $390 million.

6.   BANK BORROWINGS

     Included in short-term bank borrowings are notes and loans which are
     payable under available lines of credit maintained in the U.S., as well as
     short-term borrowings by foreign subsidiaries through local banks. Where
     borrowings are made on a discounted basis, the discount is amortized over
     the term of the loan on a straight-line basis. The average rate on
     outstanding borrowings was 7.67% and 7.32% at the end of 1996 and 1995,
     respectively. The Company's lines of credit may be withdrawn at the
     discretion of the banks and do not require commitment fees or compensating
     balance arrangements. The Company has $100 million of available line of
     credit, of which $17 million was utilized at December 31, 1996. Included in
     other non-current liabilities at December 31, 1996 and 1995 are $1,823 and
     $2,398, respectively, of long-term borrowings of a foreign subsidiary. The
     outstanding amounts relate principally to term loans payable through March,
     2001. Such borrowings bear interest rates from 12% to 15.5%.

     The Company and its wholly owned U.S. subsidiaries file a consolidated
     federal income tax return. The Company's federal tax provision is shown net
     of tax credits. As of December 31, 1996, the Company has tax carryforwards
     relating to foreign tax of $793, which expire in years 1999 through 2002.
     The foreign tax credit carryforward has been offset by a $242 valuation
     allowance. The Company also has approximately $4,372 of U.S. net operating
     loss carryforwards which expire in years through 2004 that are subject to
     limitations under provisions of the Internal Revenue Code. In addition, the
     Company has approximately $769 of state net operating loss carryforwards.
     As a result of the acquisition of Atlas Copco Robbins Inc. ("ACR"), the
     Company has additional carryforwards relating to foreign tax credits of
     approximately $607, research and development credits of $383, alternative
     minimum tax credit carryforward of approximately $79, investment tax 
     credit carryforwards of approximately $15 and a net operating loss 
     carryforward of $874, all of which are limited to the separate company 
     tax liability of ACR and by Internal Revenue Code Section 382. In 
     addition, as a result of the METCO acquisition, the company has additional
     federal net operating loss carryforwards of $19,430 which expire in years
     through 2009 and is limited to the separate company tax liability of METCO
     and by Internal Revenue Code Section 382 and state net operating loss 
     carryforward of $85,460. The METCO state carryforward, as well as the ACR
     NOL and tax credit carryforwards, have been offset by a 100% valuation 
     allowance.

     As of December 31, 1996, no provision has been made for deferred income
     taxes on approximately $2,493 of undistributed earnings of its foreign
     subsidiaries which are permanently reinvested. The Company also has a
     federal capital loss carryforward of $869, which can be used only against
     capital gains and expires in 1997. The federal capital loss carryforward
     has been offset by a 100% valuation allowance.

     Deferred income taxes reflect (a) the net tax effects of temporary
     differences between the carrying amounts of assets and liabilities for
     financial reporting purposes and the amounts used for income tax purposes,
     (b) the net tax effects of operating losses and (c) tax credit
     carryforwards. The effects of significant items comprising the Company's
     net deferred tax asset and liability as of December 31, 1996 and 1995 are
     as follows:

     The Company has recorded a deferred tax asset of $19,079 relating to net
     operating loss and tax credit carryforwards, before a valuation allowance
     of $8,937. Realization of the Company's deferred tax asset is dependent on
     generating sufficient taxable income prior to the expiration of the loss
     carryforwards. Although realization is not assured, management believes it
     is more likely than not that the net deferred tax assets will be realized.

     The Company has certain tax contingencies. Management believes the Company
     has adequate accruals. However, events and circumstances may change in the
     near term, which could require an adjustment to the accruals.

8.   PENSION AND OTHER BENEFIT PLANS

     The Company sponsors a defined benefit pension plan for substantially all
     of its U.S. subsidiaries except CP, ACR and METCO (the "Plan").
     Substantially, all employees of the included entities are eligible to
     participate in the Plan. Effective January 1, 1995, Uniroc Inc. became a
     member of the Plan. Benefits under the defined benefit pension plan are
     based upon years of service and compensation levels. In addition, CP
     sponsors several defined benefit pension plans for employees who are
     members of various unions. Benefits under the defined benefit pension plans
     are based upon years of service and terms included in the related
     collective bargaining agreements.

     Net periodic pension cost for 1996 and 1995 for the Plan consisted of the
     following components:

     The benefit obligation for 1996 and 1995 was determined using an assumed
     discount rate of 7.5% and 7%, respectively. An assumed long-term rate of
     compensation increase of 4.75% and 5.0% was used for 1996 and 1995,
     respectively. The assumed long-term rate of return on plan assets was 8.5%
     for 1996 and 8% for 1995. Plan assets consist principally of stocks and
     bonds.

9.   POSTRETIREMENT BENEFIT OBLIGATIONS

     The Company provides postretirement health care and other benefits to its
     eligible United States retirees and their dependents. Eligibility for
     benefits depends upon age and years of service.

     Net periodic postretirement benefit cost for 1996 and 1995 consisted of the
     following components:

     The postretirement benefit obligation for 1996 and 1995 consisted of the
     following components:

     The estimated current portion of the above liability is included in
     accounts payable and accrued expenses. The accumulated postretirement
     benefit obligation for 1996 and 1995 was determined using a weighted
     average discount rate of 7.5% and 7%, respectively. Other than CP, for
     measurement purposes, a 9.5% pre-65 and a 7.5% post-65 annual increase in
     per-capita costs of health care benefits were assumed for 1997 to 1998
     gradually declining by 1% per year thereafter, until they reach a constant
     annual rate of 5.5%. For CP, a 9.8% annual increase in per-capita costs of
     health care benefits was assumed for 1996 to 1997 gradually declining to
     5.1% over an eight year period. The health care cost trend rate assumption
     has a significant effect on the amounts reported. For example, a 1%
     increase in the health care cost trend rate would increase the accumulated
     postretirement benefit obligation by $3,777 at December 31, 1996 and
     increase the aggregate of total service cost and interest cost components
     of net periodic postretirement benefit cost for 1996 by $417.

10.  TRANSACTIONS WITH AFFILIATES

     The Company is a member of a group of affiliated companies and has
     extensive transactions and relationships with members of that Group (see
     note 1).


                                       15

<PAGE>

     Amounts due to affiliates include short-term debt and trade purchases. A
     portion of the Company's short-term debt is funded by ACAB. The short-term
     borrowings at the end of 1996 and 1995 were $158,038 and $122,831,
     respectively, including accrued interest. Total interest paid for these
     borrowings was $12,372 in 1996 and $7,048 in 1995. The average interest
     rates for the outstanding borrowings at year end were 6.19% in 1996 and
     5.99% in 1995.

     Amounts due to affiliates (long-term) relates to borrowings from ACAB at
     the end of 1996 totaling $300 million. The carrying value of such
     borrowings approximates fair value. Such amount matures as follows: $100
     million in 1998, $135 million in 2000 and $65 million in 2002. The average
     interest rate for the outstanding borrowings at December 31, 1996 and 1995
     was 6.72% and 6.65%, respectively. Interest was accrued on the long-term
     debt from ACAB in 1996.

     Sales to affiliated companies of $123,150 and $84,369 in 1996 and 1995,
     respectively, are included in the accompanying consolidated financial
     statements.

     Inventory purchases from affiliated companies were $137,907 and $114,766 in
     1996 and 1995, respectively. The majority of these purchases were made from
     affiliates in Belgium, Sweden and Canada. Purchases are payable in U.S.
     dollars.

     From time to time, the Company has negotiated agreements with certain
     affiliated companies to provide for the reimbursement of identifiable
     expenses incurred in assisting them in their expansion, warranty, research
     and development and various other programs in the Unites States.
     Accordingly, approximately $1,174 and $1,039 of such reimbursed expenses in
     1996 and 1995, respectively, have been included as a reduction of expenses
     in the determination of operating results.

11.  LEASE TRANSACTIONS

     Rental and lease expense charged to operations by the Company under
     operating leases amounted to $6,728 and $5,483 in 1996 and 1995,
     respectively. These leases cover principally warehouses, offices and other
     facilities, and certain equipment. The Company has certain leases for
     property and equipment that are accounted for as capital leases.

     The Company's future minimum lease payments under noncancelable operating
     and capital leases having initial or remaining lease terms in excess of one
     year as of December 31, 1996 are as follows:

     As of December 31, 1996, the Company had total available irrevocable
     letters of credit facilities of $86,390, of which $42,941 was outstanding.
     Of the $86,390, $55,000 relates to joint letters of credit/lines of credit
     facilities. To the extent that $55,000 of the letters of credit facilities
     are used, the availability under the Company's lines of credit (see note 6)
     is decreased and vice-versa. Such irrevocable commercial and standby
     letters of credit facilities support various agreements, leases and
     insurance policies.

     As of December 31, 1996, the Company has guaranteed approximately $787
     which primarily covers a subsidiary's performance with respect to specific
     projects. A subsidiary of the Company has guaranteed a sister company's
     performance relating to a project in the amount of $6 million.

14.  LITIGATION

     The Company has been named co-defendant in a number of product liability
     legal actions, as well as certain employee discrimination actions. Also,
     the Company has been notified by a party that such party may assert a claim
     against the Company for non-performance under a contract, if the party is
     unsuccessful in negotiating a change order with the project owner. The
     claim, if asserted, could be significant.

     Based on the facts and circumstances of each of the individual actions and
     the unasserted claim, management is of the opinion that the ultimate
     outcome of these matters will not have a material adverse effect on the
     consolidated financial statements of the Company.
