TO THE HOLDERS OF COMMON STOCK OF BUCYRUS INTERNATIONAL, INC.:
 
                                 INTRODUCTION
 
  BUCYRUS ACQUISITION CORP., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of AMERICAN INDUSTRIAL PARTNERS ACQUISITION COMPANY,
LLC, a Delaware limited liability company ("Parent"), hereby offers to
purchase any and all issued and outstanding shares of common stock ("Common
Stock"), par value $.01 per share (the "Shares") of Bucyrus International,
Inc., a Delaware corporation (the "Company"), at a price of $18.00 per Share
(the "Offer Price"), net to the seller in cash, 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 stockholders will not
be obligated to pay brokerage fees or commissions or, except as set forth in
Instruction 6 of the Letter of Transmittal, transfer taxes on the sale of
Shares pursuant to the Offer. The Purchaser will pay all fees and expenses
incurred of MacKenzie Partners, Inc., which is acting as the Information Agent
(the "Information Agent") in connection with the Offer, and American Stock
Transfer & Trust Company which is acting as the Depositary (the "Depositary")
in connection with the Offer.
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER, THAT NUMBER
OF SHARES OF COMMON STOCK WHICH REPRESENTS AT LEAST FIFTY-ONE PERCENT (51%) OF
THE SHARES OUTSTANDING ON A FULLY DILUTED BASIS (THE "MINIMUM CONDITION"). SEE
SECTION 14. As used in this Offer to Purchase, "fully diluted basis" takes
into account the conversion or exercise of all outstanding options and other
rights and securities exercisable or convertible into shares of Common Stock.
The Company has informed the Purchaser that, as of August 21, 1997, there were
(i) 10,534,574 shares of Common Stock issued and outstanding and (ii)
outstanding options and other rights to purchase an aggregate of 626,000
shares of Common Stock. The Merger Agreement (as defined below) provides,
among other things, that the Company will not, without the prior written
consent of Parent, issue any additional Shares (except on the exercise of
outstanding options and other rights and securities). Based on the foregoing
and giving effect to the exercise of all outstanding options and other rights,
the Purchaser believes that the Minimum Condition will be satisfied if
5,691,893 shares of Common Stock are validly tendered and not withdrawn prior
to the expiration of the Offer.
 
  As a condition and inducement to Parent's and the Purchaser's entering into
the Merger Agreement and incurring the liabilities therein concurrently with
the execution and delivery of the Merger Agreement, Jackson National Life
Insurance Company, a Michigan corporation (the "Stockholder"), which together
with PPM America, Inc., a Delaware corporation, shares voting power and
dispositive power with respect to 4,228,382 Shares, has entered into a
Stockholder Agreement (the "Stockholder Agreement"), dated as of August 21,
1997, with Parent and the Purchaser. Pursuant to the Stockholder Agreement,
the Stockholder has agreed, among other things, to tender its Shares in the
Offer, to grant Parent a proxy with respect to the voting of such Shares in
favor of the Merger and to grant Parent an option (the "JNL Option") with
respect to such Shares upon the terms and subject to the conditions set forth
therein.
 
  As an inducement to the Company's entering into the Merger Agreement,
concurrently with the execution and delivery of the Merger Agreement, American
Industrial Partners Capital Fund II, L.P., a Delaware limited partnership
("AIP Capital Fund"), and the Company have entered into a Guarantee, dated as
of August 21, 1997 (the "Guarantee"), pursuant to which, among other things,
AIP Capital Fund has agreed unconditionally and irrevocably, for the benefit
of the Company to guarantee the performance of all obligations of Parent and
the Purchaser pursuant to the Merger Agreement; provided that the aggregate
liability to which AIP Capital Fund may become subject pursuant to the
Guarantee or otherwise in connection with the transactions contemplated by the
Merger Agreement will not in any event exceed $7,000,000. The Guarantee
terminates upon the earliest of (i) the consummation of the Merger, (ii)
October 7, 2004 or (iii) the performance of all obligations of Parent and the
Purchaser pursuant to the Merger Agreement.
<PAGE>
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of August 21, 1997 (the "Merger Agreement"), by and among Parent, the
Purchaser and the Company pursuant to which, as soon as practicable after the
completion of the Offer and satisfaction or waiver, if permissible, of all
conditions to the Merger (as defined below), the Purchaser will be merged with
and into the Company and the separate corporate existence of the Purchaser
will thereupon cease. The merger, as effected pursuant to the immediately
preceding sentence, is referred to herein as the "Merger," and the Company as
the surviving corporation of the Merger is sometimes herein referred to as the
"Surviving Corporation." At the effective time of the Merger (the "Effective
Time"), each share of Common Stock then outstanding (other than Shares held by
Parent or the Purchaser and Shares held by stockholders who properly perfect
their dissenters' rights under Delaware law) will be cancelled and
extinguished and converted into the right to receive the Offer Price or any
higher price per share of Common Stock paid in the Offer (the "Merger
Consideration"), in cash payable to the holder thereof without interest. The
Merger Agreement is more fully described in Section 11.
 
  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT, AND THE TRANSACTIONS CONTEMPLATED THEREBY INCLUDING THE OFFER AND
THE MERGER AND DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR
TO, AND IN THE BEST INTERESTS OF, THE HOLDERS OF THE COMMON STOCK, AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES.
 
  Jefferies & Company, Inc., the Company's financial advisor ("Jefferies"),
has delivered to the Company's Board of Directors its written opinion (the
"Fairness Opinion") to the effect that the consideration to be received by the
holders of Common Stock pursuant to the Offer and under the terms of the
Merger Agreement, is fair to such holders, from a financial point of view.
Such opinion is set forth in full as an exhibit to the Company's
Solicitation/Recommendation Statement on Schedule 14D-9 (the "Schedule 14D-9")
that is being mailed to stockholders of the Company.
 
  The Merger Agreement provides that the initial scheduled expiration date of
the Offer shall be twenty (20) business days after the date the Offer is
commenced, but that if all conditions to the Offer shall not have been
satisfied or waived by such date, the Purchaser may, from time to time, in its
sole discretion, extend the expiration date. In addition, the Merger Agreement
provides that the Purchaser shall, on the terms and subject to the prior
satisfaction or waiver of the conditions of the Offer, accept for payment and
purchase, as soon as permitted under the terms of the Offer, all Shares
validly tendered and not withdrawn prior to the expiration of the Offer;
provided, however, that if, immediately prior to the initial expiration date
of the Offer (as it may be extended), the Shares tendered and not withdrawn
pursuant to the Offer equal less than 90% of the outstanding shares of Common
Stock, the Purchaser may extend the Offer for a period not to exceed ten (10)
business days, notwithstanding that all conditions to the Offer are satisfied
as of such expiration date of the Offer, so long as the Purchaser expressly
irrevocably waives any condition (other than the Minimum Condition) that
subsequently may not be satisfied during such extension of the Offer. The
Offer will not remain open following the time Shares are accepted for payment.
 
  Consummation of the Merger is conditioned upon, among other things, the
approval and adoption by the requisite vote of stockholders of the Company of
the Merger Agreement, if required by applicable law in order to consummate the
Merger. See Section 11. Under the Delaware General Corporation Law (the
"DGCL"), except as otherwise provided below, the affirmative vote of a
majority of the outstanding shares of Common Stock is required to approve the
Merger Agreement and the Merger.
 
  Under Section 253 of the DGCL, if a corporation owns at least 90% of the
outstanding shares of each class of another corporation, the corporation
holding such stock may merge such other corporation into itself without any
action or vote on the part of the board of directors or the stockholders of
such other corporation (a "short-form merger"). In the event that Parent and
the Purchaser acquire in the aggregate at least 90% of the outstanding shares
of Common Stock pursuant to the Offer or otherwise, then, at the election of
Parent, a short-form merger could be effected without any approval of the
Board of Directors or the stockholders of the Company, subject to compliance
with the provisions of Section 253 of the DGCL. Even if Parent and the
 
                                       2
<PAGE>
 
Purchaser do not own 90% of the outstanding shares of Common Stock following
consummation of the Offer, Parent and the Purchaser could seek to purchase
additional shares in the open market or otherwise in order to reach the 90%
threshold and employ a short-form merger. The per share consideration paid for
any Shares so acquired may be greater or less than that paid in the Offer.
Parent presently intends to effect a short-form merger if permitted to do so
under the DGCL.
 
  THIS OFFER TO PURCHASE AND THE RELATED LETTER OF TRANSMITTAL CONTAIN
IMPORTANT INFORMATION AND SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY DECISION
IS MADE WITH RESPECT TO THE OFFER.
 
                                   THE OFFER
 
  1.  TERMS OF THE OFFER. Upon the terms and subject to the conditions of the
Offer, the Purchaser 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 of this Offer to Purchase. The term "Expiration
Date" shall mean 12:00 Midnight, New York City time, on Tuesday, September 23,
1997, unless and until the Purchaser, in accordance with the terms of the
Merger Agreement, 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 Purchaser, shall expire.
 
  The Offer is conditioned upon, among other things, the satisfaction of the
Minimum Condition, the receipt, and immediate availability of financing
sufficient in amount to enable the Purchaser to consummate the Offer and the
Merger, and to refinance certain indebtedness for borrowed money of the
Company and to pay related fees and expenses, and the expiration or
termination of all waiting periods imposed by the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended, and the regulations thereunder (the "HSR
Act"). See Section 14. If such conditions are not satisfied prior to the
Expiration Date, the Purchaser reserves the right (but shall not be obligated)
to (i) decline to purchase any of the Shares tendered and terminate the Offer,
subject to the terms of the Merger Agreement, (ii) waive any of the conditions
to the Offer, to the extent permitted by applicable law and the provisions of
the Merger Agreement, and, subject to complying with applicable rules and
regulations of the Securities and Exchange Commission (the "Commission"),
purchase all Shares validly tendered or (iii) subject to the terms of the
Merger Agreement, extend the Offer and, subject to the right of stockholders
to withdraw Shares until the Expiration Date, retain the Shares which will
have been tendered during the period or periods for which the Offer is open or
extended.
 
  Subject to the terms of the Merger Agreement, the Purchaser expressly
reserves the right, in its sole discretion, at any time or from time to time,
(i) to extend the period of time during which the Offer is open and thereby
delay acceptance for payment of, and the payment for, any Shares, by giving
oral or written notice of such extension to the Depositary and (ii) to amend
the Offer in any respect (including, without limitation, by decreasing or
increasing the Offer Price and/or by decreasing the number of Shares being
sought in the Offer), by giving oral or written notice of such amendment to
the Depositary. The rights reserved by the Purchaser in this paragraph are in
addition to the Purchaser's rights to terminate the Offer as described in
Section 14. Any extension, amendment or termination will be followed as
promptly as practicable by public announcement thereof, the announcement in
the case of an extension to be issued no later than 9:00 a.m., New York City
time, on the next business day after the previously scheduled Expiration Date
in accordance with the public announcement requirements of Rule 14d-4(c) under
the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Without
limiting the obligation of the Purchaser under such Rule or the manner in
which the Purchaser may choose to make any public announcement, the Purchaser
currently intends to make announcements by issuing a press release to the Dow
Jones News Service. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE OFFER
PRICE TO BE PAID BY THE PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION
OF THE OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.
 
  The Merger Agreement provides that the Purchaser will not amend or waive the
Minimum Condition and will not decrease the Offer Price or change the form of
consideration payable in the Offer or decrease the number
 
                                       3
<PAGE>
 
of Shares sought, or impose additional conditions to the Offer, or amend any
other term of the Offer in any manner adverse to the holders of the Shares
without the written consent of the Company; provided, however, that if on the
initial scheduled Expiration Date of the Offer, which is twenty business days
after the date the Offer is commenced, all conditions to the Offer shall not
have been satisfied or waived, the Purchaser may, from time to time, in its
sole discretion, extend the Expiration Date. In addition, under the terms of
the Merger Agreement, if, immediately prior to the initial Expiration Date,
the Shares tendered and not withdrawn equal less than 90% of the outstanding
shares of Common Stock, the Purchaser may extend the Offer for a period not to
exceed ten (10) business days, notwithstanding that all conditions to the
Offer may have been satisfied, so long as the Purchaser expressly irrevocably
waives any condition (other than the Minimum Condition) that subsequently may
not be satisfied during such extension of the Offer.
 
  If the Purchaser extends the Offer, or if the Purchaser (whether before or
after its acceptance for payment of Shares) is delayed in its purchase of or
payment for Shares or is unable to pay for Shares pursuant to the Offer for
any reason, then, without prejudice to the Purchaser's rights under the Offer,
the Depositary may retain tendered Shares on behalf of the Purchaser, and such
Shares may not be withdrawn except to the extent tendering stockholders are
entitled to withdrawal rights as described in Section 4. However, the ability
of the Purchaser to delay the payment for Shares which the Purchaser has
accepted for payment is limited by Rule 14e-l(c) under the Exchange Act, which
requires that a bidder pay the consideration offered or return the securities
deposited by or on behalf of holders of securities promptly after the
termination or withdrawal of the Offer.
 
  If the Purchaser makes a material change in the terms of the Offer or the
information concerning the Offer or waives a material condition of the Offer,
the Purchaser will disseminate additional tender offer materials and extend
the Offer to the extent required by Rules 14d-4(c), 14d-6(d) and 14e-1 under
the Exchange Act. The minimum period during which the Offer must remain open
following material changes in the terms of the Offer or information concerning
the Offer, other than a change in price or a change in percentage of
securities sought, will depend upon the facts and circumstances then existing,
including the relative materiality of the changed terms or information. In a
public release, the Commission has stated that in its view an offer must
remain open for a minimum period of time following a material change in the
terms of the Offer and that waiver of a material condition, such as the
Minimum Condition, is a material change in the terms of the Offer. The release
states that an offer should remain open for a minimum of five business days
from the date a material change is first published, sent or given to security
holders and that, if material changes are made with respect to information not
materially less significant than the offer price and the number of shares
being sought, a minimum of ten business days may be required to allow adequate
dissemination and investor response. The requirement to extend the Offer will
not apply to the extent that the number of business days remaining between the
occurrence of the change and the then-scheduled Expiration Date equals or
exceeds the minimum extension period that would be required because of such
amendment. As used in this Offer to Purchase, "business day" has the meaning
set forth in Rule 14d-1 under the Exchange Act.
 
  The Company has provided the Purchaser with the Company's stockholder lists
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 by the Purchaser to record holders of Shares and
will be furnished by the Purchaser to brokers, dealers, banks 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.
 
  2. ACCEPTANCE FOR PAYMENT AND PAYMENT. Upon the terms and subject to the
conditions of the Offer (including, if the Offer is extended or amended, the
terms and conditions of any such extension or amendment), the Purchaser will
accept for payment and will pay, promptly after the Expiration Date, for all
Shares validly tendered prior to the Expiration Date and not properly
withdrawn in accordance with Section 4. All determinations concerning the
satisfaction of such terms and conditions will be within the Purchaser's
discretion, which determinations will be final and binding. See Sections 1 and
14. The Purchaser expressly reserves the right, in its sole discretion, to
delay acceptance for payment of or payment for Shares in order to comply in
whole
 
                                       4
<PAGE>
 
or in part with any applicable law, including, without limitation, the HSR
Act. Any such delays will be effected in compliance with Rule 14e-l(c) under
the Exchange Act (relating to a bidder's obligation to pay the consideration
offered or return the securities deposited by or on behalf of holders of
securities promptly after the termination or withdrawal of such bidder's
offer).
 
  In all cases, payment for Shares accepted for payment pursuant to the Offer
will be made only after timely receipt by the Depositary of (i) certificates
for such Shares (or a timely Book-Entry Confirmation (as defined below) with
respect thereto), (ii) a Letter of Transmittal (or facsimile thereof),
properly completed and duly executed, with any required signature guarantees,
or, in the case of a book-entry transfer, an Agent's Message (as defined
below), and (iii) any other documents required by the Letter of Transmittal.
The per share consideration paid to any holder of Common Stock pursuant to the
Offer will be the highest per Share consideration paid to any other holder of
such shares pursuant to the Offer.
 
  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn as, if and when the Purchaser gives oral or written notice to
the Depositary of the Purchaser's acceptance for payment of such Shares.
Payment for Shares accepted for payment pursuant to the Offer will be made by
deposit of the purchase price therefor with the Depositary, which will act as
agent for tendering stockholders for the purpose of receiving payment from the
Purchaser and transmitting payment to tendering stockholders. UNDER NO
CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE TO BE PAID BY THE
PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY
DELAY IN MAKING SUCH PAYMENT.
 
  If the Purchaser is delayed in its acceptance for payment of, or payment
for, Shares or is unable to accept for payment or pay for Shares pursuant to
the Offer for any reason, then, without prejudice to the Purchaser's rights
under the Offer (including such rights as are set forth in Sections 1 and 14)
(but subject to compliance with Rule 14e-1(c) under the Exchange Act), the
Depositary may, nevertheless, on behalf of the Purchaser, retain tendered
Shares, and such Shares may not be withdrawn except to the extent tendering
stockholders are entitled to exercise, and duly exercise, withdrawal rights as
described in Section 4.
 
  If any tendered Shares are not purchased pursuant to the Offer for any
reason, certificates for any such Shares will be returned, without expense to
the tendering stockholder (or, in the case of Shares delivered by book-entry
transfer of such Shares into the Depositary's account at the Book-Entry
Transfer Facility (as defined below) pursuant to the procedures set forth in
Section 3, such Shares will be credited to an account maintained at the Book-
Entry Transfer Facility), as promptly as practicable after the expiration or
termination of the Offer.
 
  The Purchaser reserves the right to transfer or assign, in whole or in part,
to Parent or to any affiliate of Parent, the right to purchase Shares tendered
pursuant to the Offer, but any such transfer or assignment will not relieve
the Purchaser of its obligations under the Offer and will in no way prejudice
the rights of tendering stockholders to receive payment for Shares validly
tendered and accepted for payment pursuant to the Offer.
 
  3. PROCEDURE FOR TENDERING SHARES.
 
  Valid Tender. For Shares to be validly tendered pursuant to the Offer,
either (i) a properly completed and duly executed Letter of Transmittal (or
facsimile thereof), together with any required signature guarantees, or in the
case of a book-entry transfer, an Agent's Message (as defined below), 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 and either certificates for tendered Shares must be received
by the Depositary at one of such addresses or such Shares must be delivered
pursuant to the procedures for book-entry transfer set forth below (and a
Book-Entry Confirmation received by the Depositary), in each case, prior to
the Expiration Date or (ii) the tendering stockholder must comply with the
guaranteed delivery procedures set forth below.
 
  The Depositary will establish an account with respect to the Shares at The
Depositary Trust Company or the Philadelphia Depositary Trust Company (either,
the "Book-Entry Transfer Facility") for purposes of the
 
                                       5
<PAGE>
 
Offer within two business days after the date of this Offer to Purchase. Any
financial institution that is a participant in the Book-Entry Transfer
Facility's systems may make book-entry delivery of Shares by causing the Book-
Entry Transfer Facility to transfer such Shares into the Depositary's account
in accordance with the Book-Entry Transfer Facility's procedure for such
transfer. However, although delivery of Shares may be effected through book-
entry transfer into the Depositary's account at the Book-Entry Transfer
Facility, the Letter of Transmittal (or facsimile thereof), properly completed
and duly executed, with any required signature guarantees, or an Agent's
Message, 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 prior to the Expiration Date, or the
tendering stockholder must comply with the guaranteed delivery procedures
described below. The confirmation of a book-entry transfer of Shares into the
Depositary's account at the Book-Entry Transfer Facility as described above is
referred to herein as a "Book-Entry Confirmation." DELIVERY OF DOCUMENTS TO
THE BOOK-ENTRY TRANSFER FACILITY IN ACCORDANCE WITH SUCH BOOK-ENTRY TRANSFER
FACILITY'S PROCEDURES DOES NOT CONSTITUTE DELIVERY TO THE DEPOSITARY.
 
  The term "Agent's Message" means a message transmitted by the Book-Entry
Transfer Facility to, and received by, the Depositary and forming a part of a
Book-Entry Confirmation, which states that such Book-Entry Transfer Facility
has received an express acknowledgment from the participant in such Book-Entry
Transfer Facility tendering the Shares that such participant has received and
agrees to be bound by the terms of the Letter of Transmittal and that the
Purchaser may enforce such agreement against the participant.
 
  THE METHOD OF DELIVERY OF SHARES, THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS, INCLUDING DELIVERY THROUGH THE BOOK-ENTRY TRANSFER
FACILITY, IS AT THE ELECTION 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 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.
 
  Signature Guarantees. No signature guarantee is required on the Letter of
Transmittal (i) if the Letter of Transmittal is signed by the registered
holder(s) (which term, for purposes of this Section, includes any participant
in the Book Entry Transfer Facility's systems whose name appears on a security
position listing as the owner of the Shares) of Shares tendered therewith and
such registered holder has not completed either the box entitled "Special
Delivery Instructions" or the box entitled "Special Payment Instructions" on
the Letter of Transmittal or (ii) if such Shares are tendered for the account
of a financial institution (including most commercial banks, savings and loan
associations and brokerage houses) that is a participant in the Security
Transfer Agent's Medallion Program, the New York Stock Exchange Medallion
Signature Guarantee Program or the Stock Exchange Medallion Program (each, an
"Eligible Institution" and, collectively, "Eligible Institutions"). In all
other cases, all signatures on Letters of Transmittal must be guaranteed by an
Eligible Institution. See Instructions 1 and 5 to the Letter of Transmittal.
If the certificates for Shares are registered in the name of a person other
than the signer of the Letter of Transmittal, or if payment is to be made, or
certificates for Shares not tendered or not accepted for payment are to be
returned, to a person other than the registered holder of the certificates
surrendered, then the tendered certificates for such Shares must be endorsed
or accompanied by appropriate stock powers, in either case, signed exactly as
the name or names of the registered holders or owners appear on the
certificates, with the signatures on the certificates or stock powers
guaranteed as aforesaid. 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 the procedures for book-entry transfer cannot be completed on a
timely basis or time will not permit all required documents to reach the
Depositary prior to the Expiration Date, such stockholder's tender may be
effected if all the following conditions are met:
 
    (i) such tender is made by or through an Eligible Institution;
 
    (ii) a properly completed and duly executed Notice of Guaranteed
  Delivery, substantially in the form provided by the Purchaser, is received
  by the Depositary, as provided below, prior to the Expiration Date; and
 
                                       6
<PAGE>
 
    (iii) the certificates for (or a Book-Entry Confirmation with respect to)
  such Shares, together with a properly completed and duly executed Letter of
  Transmittal (or facsimile thereof), with any required signature guarantees,
  or, in the case of a book-entry transfer, an Agent's Message, and any other
  required documents are received by the Depositary within three trading days
  after the date of execution of such Notice of Guaranteed Delivery. A
  "trading day" is any day on which the National Association of Securities
  Dealers Automated Quotation System, Inc. (the "NASDAQ") is open for
  business.
 
  The Notice of Guaranteed Delivery may be delivered by hand to the Depositary
or transmitted by telegram, facsimile transmission or mail to the Depositary
and must include a guarantee by an Eligible Institution in the form set forth
in such Notice of Guaranteed 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 (or a timely Book-Entry
Confirmation with respect to) such Shares, (ii) a Letter of Transmittal (or
facsimile thereof), properly completed and duly executed, with any required
signature guarantees, or, in the case of a book-entry transfer, an Agent's
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 TO BE PAID BY THE PURCHASER FOR THE
SHARES, REGARDLESS OF ANY EXTENSION OF THE OFFER OR ANY DELAY IN MAKING SUCH
PAYMENT.
 
  The valid tender of Shares pursuant to one of the procedures described above
will constitute a binding agreement between the tendering stockholder and the
Purchaser upon the terms and subject to the conditions of the Offer.
 
  Appointment. By executing the Letter of Transmittal as set forth above, the
tendering stockholder will irrevocably appoint designees of the Purchaser, and
each of them, as such stockholder's attorneys-in-fact and proxies in the
manner set forth in the Letter of Transmittal, each with full power of
substitution, to the full extent of such stockholder's rights with respect to
the Shares tendered by such stockholder and accepted for payment by the
Purchaser and with respect to any and all other Shares or other securities or
rights issued or issuable in respect of such Shares. All such proxies will be
considered coupled with an interest in the tendered Shares. Such appointment
will be effective when, and only to the extent that, the Purchaser accepts for
payment Shares tendered by such stockholder as provided herein. Upon such
appointment, all prior powers of attorney, proxies and consents given by such
stockholder with respect to such Shares or other securities or rights will,
without further action, be revoked and no subsequent powers of attorney,
proxies, consents or revocations may be given by such stockholder (and, if
given, will not be deemed effective). The designees of the Purchaser will
thereby be empowered to exercise all voting and other rights with respect to
such Shares and other securities or rights, including, without limitation, in
respect of any annual, special or adjourned meeting of the Company's
stockholders, actions by written consent in lieu of any such meeting or
otherwise, as they in their sole discretion deem proper. The Purchaser
reserves the right to require that, in order for Shares to be deemed validly
tendered, immediately upon the Purchaser's acceptance for payment of such
Shares, the Purchaser must be able to exercise full voting, consent and other
rights with respect to such Shares and other related securities or rights,
including voting at any meeting of stockholders.
 
  Determination of Validity. All questions as to the validity, form,
eligibility (including time of receipt) and acceptance of any tender of Shares
will be determined by the Purchaser, in its sole discretion, which
determination will be final and binding. The Purchaser reserves the absolute
right to reject any or all tenders of any Shares determined by it not to be in
proper form or the acceptance for payment of, or payment for which may, in the
opinion of the Purchaser's counsel, be unlawful. The Purchaser also reserves
the absolute right, in its sole discretion, subject to the provisions of the
Merger Agreement, to waive any of the conditions of the Offer or any defect or
irregularity in the tender of any Shares of any particular stockholder,
whether or not similar defects or irregularities are waived in the case of
other stockholders. No tender of Shares will be deemed to have been validly
made until all defects or irregularities relating thereto have been cured or
waived. None of the Purchaser,
 
                                       7
<PAGE>
 
Parent, the Depositary, the Information Agent, the Company 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.
Subject to the terms of the Merger Agreement, the Purchaser's interpretation
of the terms and conditions of the Offer (including the Letter of Transmittal
and the instructions thereto) will be final and binding.
 
  Backup Withholding. Under the "backup withholding" provisions of federal
income tax law, unless a tendering registered holder, or his assignee (in
either case, the "Payee"), satisfies the conditions described in Instruction 9
of the Letter of Transmittal or is otherwise exempt, the cash payable as a
result of the Offer may be subject to backup withholding tax at a rate 31% of
the gross proceeds. To prevent backup withholding, each Payee should complete
and sign the Substitute Form W-9 provided in the Letter of Transmittal. See
Instruction 9 of the Letter of Transmittal.
 
  4. WITHDRAWAL RIGHTS. Except as otherwise provided in this Section 4,
tenders of Shares are irrevocable. Shares tendered pursuant to the Offer may
be withdrawn pursuant to the procedures set forth below at any time prior to
the Expiration Date and, unless theretofore accepted for payment and paid for
by the Purchaser pursuant to the Offer, may also be withdrawn at any time
after September 23, 1997.
 
  For a withdrawal to be effective, a written, telegraphic 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 and
must specify the name of the person having tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and the name of the registered
holder of the Shares to be withdrawn, if different from the name of the person
who tendered the Shares. If certificates for Shares 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 delivered pursuant
to the procedures for book-entry transfer as set forth in Section 3, any
notice of withdrawal must also specify the name and number of the account at
the appropriate Book-Entry Transfer Facility to be credited with the withdrawn
Shares and otherwise comply with such Book-Entry Transfer Facility's
procedures. Withdrawals of tenders of Shares may not be rescinded, and any
Shares properly withdrawn will thereafter be deemed not validly tendered for
purposes of the Offer. However, withdrawn Shares may be retendered by again
following one of the procedures described in Section 3 any time prior to the
Expiration Date.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, which determination will be final and binding. None of the
Purchaser, Parent, the Depositary, the Information Agent, or any other person
will be under any duty to give notification of any defects or irregularities
in any notice of withdrawal or incur any liability for failure to give any
such notification.
 
  5. CERTAIN FEDERAL INCOME TAX CONSEQUENCES. The receipt of cash for Shares
pursuant to the Offer or the Merger will be a taxable transaction for U.S.
federal income tax purposes and also may be a taxable transaction under state,
local or foreign tax laws. In general, a stockholder who tenders Shares in the
Offer or receives cash in exchange for Shares in the Merger will recognize
gain or loss for federal income tax purposes equal to the difference, if any,
between the amount of cash received and the stockholder's tax basis in the
Shares sold. Gain or loss will be determined separately for each block of
Shares (i.e., Shares acquired at the same time and price) exchanged pursuant
to the Offer or the Merger. Such gain or loss generally will be capital gain
or loss if the Shares disposed of were held as capital assets by the
stockholder, and will be long-term capital gain or loss if the Shares disposed
of were held for more than eighteen (18) months at the date of sale.
 
  A holder of Shares who perfects such stockholder's appraisal rights, if any,
under the DGCL probably will recognize gain or loss at the Effective Time in
an amount equal to the difference between the "amount realized" and such
stockholder's adjusted tax basis of such Shares. For this purpose, although
there is no authority to this effect directly on point, the amount realized
generally should equal the trading value per share of the Shares at the
Effective Time. Ordinary interest income and/or capital gain (or capital loss,
assuming that the Shares were
 
                                       8
<PAGE>
 
held as capital assets) should be recognized by such stockholder at the time
of actual receipt of payment, to the extent that such payment exceeds (or is
less than) the amount realized at the Effective Time.
 
  The foregoing summary constitutes a general description of certain U.S.
federal income tax consequences of the Offer and the Merger without regard to
the particular facts and circumstances of each stockholder of the Company and
is based on the provisions of the Internal Revenue Code of 1986, as amended,
Treasury Department Regulations issued pursuant thereto and published rulings
and court decisions in effect as of the date hereof, all of which are subject
to change, possibly with retroactive effect. Special tax consequences not
described herein may be applicable to certain stockholders subject to special
tax treatment (including, but not limited to, insurance companies, tax-exempt
organizations, financial institutions or broker dealers, foreign stockholders
and stockholders who have acquired their Shares pursuant to the exercise of
employee stock options or otherwise as compensation). ALL STOCKHOLDERS SHOULD
CONSULT THEIR TAX ADVISORS WITH RESPECT TO SPECIFIC TAX EFFECTS APPLICABLE TO
THEM OF THE OFFER AND THE MERGER, INCLUDING THE APPLICABILITY AND EFFECT OF
THE ALTERNATIVE MINIMUM TAX AND ANY STATE, LOCAL AND FOREIGN TAX LAWS.

Stock are traded on the NASDAQ under the symbol "BCYR". The following table

  On July 29, 1997, the last full trading day prior to the public announcement
of the execution of a letter of intent by the Company and AIP Capital Fund
regarding the proposed acquisition of the Company by AIP Capital Fund or an
affiliated entity, the last reported sales price of the Shares on the NASDAQ
was $12 5/8 per share of Common Stock. On August 25, 1997, the last full
trading day prior to the commencement of the Offer, the last reported sales
price of the Shares on the NASDAQ was $17 3/4 per share of Common Stock.
Stockholders are urged to obtain a current market quotation for the Shares.
 
  The payment of Common Stock dividends is restricted under the terms of an
agreement with the Company's lenders. Under such restrictions, the payment of
Common Stock dividends is not currently permitted. In addition, under the
terms of the Merger Agreement, the Company is not permitted to declare or pay
dividends on the Common Stock.
 
  7. EFFECT OF THE OFFER ON THE MARKET FOR THE SHARES; STOCK LISTING; EXCHANGE
      ACT REGISTRATION; MARGIN REGULATIONS.
 
  Market for the Shares. The purchase of Shares by the Purchaser pursuant to
the Offer will reduce the number of Shares that might otherwise trade publicly
and will reduce the number of holders of Shares, which could adversely affect
the liquidity and market value of the remaining Shares held by the public.
 
                                       9
<PAGE>
 
  Stock Listing. The Common Stock is listed on the NASDAQ. Depending upon the
number of Shares purchased pursuant to the Offer, the Shares may no longer
meet the requirements of the National Association of Securities Dealers, Inc.
(the "NASD") for continued inclusion on the NASDAQ System. The NASD requires
that an issuer have at least 100,000 publicly held shares, held by at least
300 shareholders, with a market value of at least $200,000, have total assets
of at least $2 million and have capital and surplus (total shareholders'
equity) of at least $1 million. If the NASDAQ System were to cease to publish
quotations for the Shares, it is possible that the Shares would continue to
trade in the over-the-counter market and that price or other quotations would
be reported by other sources. The extent of the public market for such Shares
and the availability of such quotations would depend, however, upon such
factors as the number of shareholders and/or the aggregate market value of
such securities remaining at such time, the interest in maintaining a market
in the Shares on the part of securities firms, the possible termination of
registration under the Exchange Act as described below, and other factors. The
Purchaser cannot predict whether the reduction in the number of Shares that
might otherwise trade publicly would have an adverse or beneficial effect on
the market price for, or marketability of, the Shares or whether it would
cause future market prices to be greater or lesser than the Offer Price. The
Company has represented that, as of August 21, 1997, 10,534,574 Shares were
issued and outstanding.
 
  Exchange Act Registration. The Shares are currently registered under the
Exchange Act. Registration of the Shares under the Exchange Act may be
terminated upon application of the Company to the Commission if the Shares are
neither listed on a national securities exchange nor held by 300 or more
holders of record. Termination of registration of the Shares under the
Exchange Act, assuming there are no other securities of the Company subject to
registration, would substantially reduce the information required to be
furnished by the Company to its stockholders and to the Commission and would
make certain provisions of the Exchange Act, such as the short-swing profit
recovery provisions of Section 16(b), the requirement of furnishing a proxy
statement pursuant to Section 14(a) in connection with stockholders' meetings
and the related requirement of furnishing an annual report to stockholders and
the requirements of Rule 13e-3 under the Exchange Act with respect to "going
private" transactions, no longer applicable to the Company. Furthermore, the
ability of "affiliates" of the Company and persons holding "restricted
securities" of the Company to dispose of such securities pursuant to Rule 144
or Rule 144A promulgated under the Securities Act of 1933, as amended (the
"Securities Act"), may be impaired or eliminated. If registration of the
Common Stock under the Exchange Act were terminated, such Shares would no
longer be "margin securities" or be eligible for continued listing on any
stock exchange. The Purchaser may seek to cause the Company to apply for
termination of registration of the Shares under the Exchange Act as soon after
the completion of the Offer as the requirements for such termination are met.
 
  If registration of the Shares is not terminated prior to the Merger, then
the Shares will be delisted from the NASDAQ and the registration of the Shares
under the Exchange Act will be terminated following the consummation of the
Merger.
 
  Margin Regulations. The Shares presently are "margin securities" under the
regulations of the Board of Governors of the Federal Reserve System (the
"Federal Reserve Board"), which status has the effect, among other things, of
allowing brokers to extend credit on the collateral of such securities.
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 the Shares under the Exchange Act were terminated, the
Shares would no longer be "margin securities."
 
  8. CERTAIN INFORMATION CONCERNING THE COMPANY.
 
  General. The information concerning the Company contained in this Offer to
Purchase, including that set forth below under the caption "Selected Financial
Information," has been furnished by the Company or has been taken from or

accuracy or completeness of the information concerning the Company contained
in such documents and records or for any failure by the Company to disclose
events which may have occurred or may affect the significance or accuracy of
any such information but which are unknown to Parent or the Purchaser.
 
  The Company is a major manufacturer of large-scale excavation equipment used
in surface mining and other earth moving operations. The Company is a Delaware
corporation with its principal executive offices at P.O. Box 500, 1100
Milwaukee Avenue, South Milwaukee, WI 53172. The telephone number of the
Company at such offices is (414) 768-4000.
 
  On August 26, 1997, the Company consummated the acquisition (the "Marion
Acquisition") of certain assets and liabilities of The Marion Power Shovel
Company, a subsidiary of Global Industrial Technologies, Inc. ("Global") and
certain subsidiaries and divisions of Global that represent Global's surface
mining equipment business in Australia, Canada and South Africa (collectively,
"Marion"). The purchase price for Marion was $40.1 million, subject to post-
closing adjustments which would have reduced the purchase price by
approximately $3.7 million if the Marion Acquisition had been consummated on
June 30, 1997. The Company financed the Marion Acquisition and related fees
and expenses using an unsecured bridge loan (the "Bridge Loan") provided by
PPM America Special Investments Fund, L.P. (the "PPM Fund"), an affiliate of
the Stockholder. The Bridge Loan was funded on August 26, 1997 (immediately
prior to consummation of the Marion Acquisition) in the amount of $45.0
million.

(1) As discussed in the Company's Form 10-K for the fiscal year ending
    December 31, 1996, the Company accounted for reorganization under Chapter
    11 of the Bankruptcy Code effective December 14, 1994 using the principles
    of fresh start reporting as required by AICPA Statement of Position 90-7,
    "Financial Reporting by Entities in Reorganization Under the Bankruptcy
    Code". Accordingly, the consolidated financial statements of the Company
    are not comparable to the consolidated financial statements of periods
    prior to December 14, 1994.
 
  Approximately 40.14% of the Shares are held by the Stockholder, who has
agreed, among other things, to tender, or cause to be tendered, all Shares
owned by it pursuant to the Offer. The Stockholder also has granted to Parent
a proxy to vote the Shares owned by them in favor of the Merger. See Section
11.
 
  Certain Company Projections. To the knowledge of Parent and the Purchaser,
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 Offer and the Merger, the Company furnished Parent
with financial projections that were prepared in connection with the senior
notes offering that the Company had been considering. These projections are
based on numerous assumptions concerning future events, and give effect to the
Marion Acquisition and the senior notes offering which was anticipated to be
$100 million at the time the projections were prepared.
 
  The Company's projections for the years 1997 through 2001anticipated total
sales of $344.5 million in 1997, increasing thereafter an average of
approximately 7.5% per year for the next four years reaching $460.0 million in
2001. Fiscal 1997 net income was projected at $10.5 million, and was projected
to increase at an average of 22.3% annually reaching $23.5 million in 2001.
EBITDA was projected to be $34.3 million in 1997 and to increase at an average
rate of approximately 9.6% per year reaching $49.5 million in 2001. The net
income amounts did not reflect the effects of purchase accounting and other
material assumptions.
 
  Such projections were prepared for the limited purpose of obtaining a rating
for the senior notes and have not been made public by the Company. They do not
reflect recent developments which have occurred since they were prepared, such
as the Offer and the Merger, the increase in the principal amount of the
senior notes offering to $150 million and the Bridge Loan. This reference to
the projections is provided solely because such projections have been provided
to the Purchaser and neither the Purchaser, Parent, or the Company believes
that such projections should be relied upon.

million. The sole general partner of AIP Capital Fund is American Industrial
Partners II, L.P., a Delaware limited partnership ("AIP II LP"). The sole
general partner of AIP II LP is American Industrial Partners Corporation, a

are collectively referred to herein as the "AIP Entities." AIP Capital Fund is
a party to the Guarantee; it is not a party to either the Merger Agreement or
the Stockholder Agreement. None of the other AIP Entities is a party to any of
the Merger Agreement, the Stockholder Agreement or the Guarantee. The offices
of each of the AIP Entities are located at One Maritime Plaza, Suite 2525, San
Francisco, California 94111.
 
                                      13
<PAGE>
 
  Parent and the Purchaser. Each of Parent and the Purchaser is a Delaware
entity, newly formed at the direction of AIP Capital Fund for the purpose of
effecting the Offer and the Merger. Parent owns all of the outstanding capital
stock of the Purchaser. AIP Capital Fund as the sole member of Parent, has
sole voting and investment power over Parent. It is not anticipated that,
prior to the consummation of the Offer, the Purchaser or Parent will have any
significant assets or liabilities or will engage in any activities other than
those incident to the Offer and the Merger and the financing thereof. The
offices of Parent and the Purchaser are located at One Maritime Plaza, Suite
2525, San Francisco, California 94111.
 
  For certain information concerning the sole member, general partners or
executive officers and directors, as the case may be, of the Purchaser, Parent
and the AIP Entities, see Schedule I. Each of the AIP Entities disclaims that
it is a "bidder" for purposes of this Offer.
 
  Pursuant to the Stockholder Agreement, Parent may be deemed to beneficially
own 4,228,382 shares of Common Stock constituting approximately 40.14% of the
total currently outstanding shares of Common Stock. Each of the Purchaser,
Parent and the AIP Entities disclaims beneficial ownership of such shares.
Except as set forth in this Offer to Purchase, none of the Purchaser, Parent
or any of the AIP Entities, nor, to the best knowledge of the Purchaser,
Parent or AIP Capital Fund, any of the persons listed on Schedule I, nor any
associate or majority-owned subsidiary of any of the foregoing, beneficially
owns or has a right to acquire any Shares, and none of the Purchaser, Parent
or any of the AIP Entities nor, to the best of knowledge of the Purchaser,
Parent or AIP Capital Fund any of the persons or entities referred to above,
nor any of the respective executive officers, directors or subsidiaries of any
of the foregoing, has effected any transaction in Shares during the past 60
days.
 
  Upon consummation of the Merger, AIP Capital Fund will be paid a fee of $4
million and reimbursed for out-of-pocket expenses in connection with the
negotiation of the Merger Agreement and for providing certain investment
banking services to the Company including the arrangement and negotiation of
the terms of the Notes and for other financial advisory and management
consulting services.
 
  AIP Capital Fund expects to provide substantial ongoing financial and
management services to the Company utilizing the extensive operating and
financial experience of AIP Capital Fund's principals. AIP Capital Fund will
receive an annual fee of $1.45 million for providing general management,
financial and other corporate advisory services to the Company, payable
semiannually 45 days after the scheduled interest payment date for the Notes
(as defined herein), and will be reimbursed for out-of-pocket expenses. The
fees will be paid to AIP Capital Fund pursuant to a management services
agreement among AIP Capital Fund, the Company and certain Company affiliates
and will be subordinated in right of payment to the Notes.
 
  AIP Capital Fund has discussed with the Company in broad terms AIP Capital
Fund's general policy that stock in the companies acquired by AIP Capital
Fund, or its affiliates, be made available to executive officers of such
acquired companies, typically in the form of stock options. However, there is
currently no agreement, arrangement or understanding specifically implementing
this policy in respect of the Company or management of the Company, nor is
there expected to be any such agreement, arrangement or understanding until
following consummation of the Merger. Following consummation of the Merger,
AIP Capital Fund expects to cause the Surviving Corporation to issue and sell
additional shares of its common stock to certain members of management of the
Company and to adopt a performance-based stock option plan for such management
which, in the aggregate, would comprise approximately 10% of the common stock
of the Surviving Corporation.
 
  Except as set forth in this Offer to Purchase, none of the Purchaser, Parent
or any of the AIP Entities, nor, to the best knowledge of the Purchaser,
Parent or AIP Capital Fund, any of the persons listed on Schedule I, 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 securities of the Company, joint ventures, loan
or option arrangements, puts or calls, guarantees of loans, guarantees against
loss, or the giving or withholding of proxies. Except as set forth in this
Offer to Purchase, none of the Purchaser, Parent or any of the AIP Entities,
or any of their respective affiliates,
 
                                      14
<PAGE>
 
nor, to the best knowledge of the Purchaser, Parent or AIP Capital Fund, any
of the persons listed on Schedule I, has had, since January 1, 1994, any
business relationships or transactions with the Company or any of its
executive officers, directors or affiliates that would require reporting under
the rules of the Commission. Except as set forth in this Offer to Purchase,
since January 1, 1994, there have been no contacts, negotiations or
transactions between the Purchaser, Parent or any of the AIP Entities, any of
their respective affiliates or, to the best knowledge of the Purchaser, Parent
or AIP Capital Fund, any of the persons listed on Schedule I, and the Company
or its affiliates concerning a merger, consolidation or acquisition, tender
offer or other acquisition of securities, election of directors or a sale or
other transfer of a material amount of assets.
 
  10. SOURCE AND AMOUNT OF FUNDS.
 
  Parent and the Purchaser estimate that the total amount of funds required by
the Purchaser to (i) purchase all of the Shares pursuant to the Offer and
finance the Merger Consideration, (ii) refinance certain existing indebtedness
and accrued liabilities of the Company, and (iii) pay fees and expenses
incurred in connection with the Offer and the Merger will be approximately
$321.3 million. Of these funds, it is anticipated that (i) approximately $5.0
million will be obtained from cash on hand of the Company, (ii) approximately
$143.0 million will be obtained from an equity contribution from AIP Capital
Fund (the "Equity Contribution"), (iii) approximately $150 million will be
obtained from the proceeds of an offering (the "Notes Offering") of Senior
Notes Due 2007 of the Company, and (iv) $23.3 million will be financed through
a revolving credit facility (the "Revolving Credit Facility"), the principal
terms of which are described below. The Revolving Credit Facility and the
Notes Offering are referred to collectively as the "Debt Financing." Should
additional financing be necessary, Parent believes that the Purchaser would
have additional funds available to it in view of the currently contemplated
capital structure of the Company. The net proceeds from the Notes Offering
will be used to fund, in part, the purchase of Shares in the Offer in the
event that at least 90% of the outstanding Shares are tendered in the Offer
and not withdrawn and the Merger becomes effective without a meeting of
stockholders of the Company in accordance with the DGCL. In the event that
fewer than 90% of the outstanding Shares are tendered in the Offer and not
withdrawn, AIP Capital Fund, or an affiliate, will loan the Purchaser an
amount that, together with AIP Capital Fund's equity contribution of $143.0
million, will be sufficient to complete the acquisition of Shares in the Offer
and Merger, such loan to be repaid upon consummation of the Merger with a
portion of the proceeds of the Notes Offering.
 
  The following table has been prepared by the Purchaser after discussions
with management of the Company and sets forth the approximate amounts,
proposed sources and uses of funds necessary to consummate the proposed Offer,
Merger and related refinancings:

  The Notes Offering. In connection with the Offer and the Merger, the Company
will issue and sell at least $150 million aggregate principal amount of debt
securities of the Company through the Notes Offering. The Company has received
a letter from a nationally recognized investment banking firm that, subject to
the conditions set forth in such letter, it is highly confident that it could
raise approximately $150 million of senior notes of the Company in a private
placement under Rule 144A under the Securities Act (with subsequent
registration rights), concurrent with (x) the initial borrowing under the
Revolving Credit Facility as contemplated below and (y) the Equity
Contribution.
 
  It is currently anticipated that the debt securities to be issued in the
Notes Offering will (i) mature in 10 years, (ii) bear interest at a rate to be
determined based on market conditions existing at the time of the offering,
(iii) have semiannual interest payment dates beginning in 1998, (iv) be
redeemable at the option of the Company beginning on the fifth anniversary of
the issue date redemption prices to be determined and (v) have such other
terms as the Company and the Purchaser of the debt securities agree.
 
  Revolving Credit Facility. In connection with the Offering, the Company has
obtained a commitment from Bank One, Wisconsin ("Bank One") to enter into a
new senior bank credit agreement, the Revolving Credit Facility. Bank One has
provided working capital and other financing, including a letter of credit
facility, to the Company since 1988. Pursuant to the Revolving Credit
Facility, the Company will replace its current $15 million letter of credit
and revolving loan facility with the $75 million Revolving Credit Facility.
The Revolving Credit Facility is expected to be used in the future for general
working capital purposes and capital expenditures. As of June 30, 1997, on a
pro forma basis after giving effect to the Marion Acquisition, approximately
$23.3 million would have been outstanding under the Revolving Credit Facility.
Borrowings under the Revolving Credit Facility bear interest at variable rates
and are subject to a borrowing base formula, which at June 30, 1997, would
have permitted borrowings and letters of credit totaling $68.7 million,
including a six month reserve for interest payments on the Revolving Credit
Facility.
 
  The $75 million Revolving Credit Facility will include a $25 million
sublimit for standby letters of credit. The issuance of standby letters of
credit will reduce the amount available for direct borrowings under the
Revolving Credit Facility. Availability under the Revolving Credit Facility
will be limited to a borrowing base which will be defined as (A) the sum of
(i) 80% of North American accounts receivable, (ii) 50% of domestic finished
goods and raw materials, (iii) a declining percentage (initially 30%) of
domestic work-in-progress, and (iv) 80% of the estimated orderly liquidation
value (as determined by a formula) of the Company and domestic subsidiaries
machinery and equipment minus (B) the sum of (i) outstanding principal balance
of other permitted debt and (ii) a reserve equal to one semi-annual interest
payment on the Notes. The obligations of the Company under the Revolving
Credit Facility will be guaranteed by certain subsidiaries, and the Revolving
Credit Facility will be secured by substantially all of the assets of the
Company, other than real property and assets of foreign subsidiaries. Pricing
on the Revolving Credit Facility is, at the option of the Company, (i) Prime
Rate or Federal Funds Rate plus 1/2 percent per annum plus an applicable
margin ranging from 0% to 0.5% dependent on the ratio of funded debt to
earnings before interest, taxes, depreciation and amortization ("EBITDA"), or
(ii) LIBOR plus an applicable margin ranging from 1.5% to 2.75% depending on
the ratio of funded debt to EBITDA. Letters of credit will be priced at 50% of
the applicable LIBOR interest rate margin for non-financial letters of credit
and 100% of the applicable LIBOR interest rate margin in the case of financial
letters of credit.
 
  The Revolving Credit Facility will contain certain restrictive covenants
that impose limitations upon, among other things, the ability of the Company
and the guarantors to incur liens; merge, consolidate or dispose of assets;
make loans and investments; incur indebtedness; engage in certain transactions
with affiliates; incur contingent obligations; enter into joint ventures;
enter into lease agreements; pay dividends and make other distributions;
change its business; redeem the Notes; and make capital expenditures.
 
  The Revolving Credit Facility also will contain covenants requiring the
Company to maintain certain financial ratios to be determined with respect to:
adjusted funded debt to EBITDA ratio; fixed charge coverage ratio; interest
coverage ratio; and, minimum net worth.
 
                                      16

  All extensions of credit under the Revolving Credit Facility will be subject
to customary documentation and the continued accuracy of all representations
and warranties as well as the absence of any material adverse effect of the
Company or defaults or event of default with respect to the Company's
indebtedness. The Revolving Credit Facility may be refinanced or increased
from time to time.
 
  Marion Acquisition Bridge Loan. The Company financed the Marion Acquisition
utilizing an unsecured bridge loan (the "Bridge Loan") provided by PPM Fund,
an affiliate of the Stockholder. The Bridge Loan was funded on August 26, 1997
(immediately prior to the consummation of the Marion Acquisition) in the
amount of $45.0 million. A portion of the Proceeds of the Notes Offering are
intended to be used to repay the Bridge Loan.
 
  The Company obtained a commitment dated April 14, 1997 from the PPM Fund to
provide the Bridge Loan ("Bridge Loan Commitment"). Upon execution of the
Bridge Loan Commitment, the Company paid a $550,000 Proposal and Commitment
Fee to the PPM Fund. The Bridge Loan Commitment provided for a fee of $450,000
(the "Facility Fee") to be paid upon execution of the definitive purchase
agreement for the Marion Acquisition. The Bridge Loan Commitment provided for
a closing date of the Marion Acquisition of not later than July 14, 1997. On
June 30, 1997, the Company and the PPM Fund agreed to extend the deadline for
the closing date until August 30, 1997 (the "Extension Agreement"). As a
condition to the Extension Agreement, however, the PPM Fund required the
Company to pay a $337,500 Extension Fee and to pay the $450,000 Facility Fee
at the time the Extension Agreement was signed.
 
  On August 26, 1997, upon consummation of the Marion Acquisition and the
funding of the Bridge Loan, the Company paid a $800,000 Financing Fee to the
PPM Fund and a Bridge Loan funding fee of $1,125,000. Additional compensation
under the Bridge Loan is due as follows: (i) if the Bridge Loan is outstanding
thirty days after funding (on September 25, 1997), the Company will pay a
"Maintenance Fee" of $800,000; (ii) if the Bridge Loan is outstanding ninety
days after funding (on November 24, 1997), the Company will pay a Maintenance
Fee of $3,200,000; and (v) if the Bridge Loan is outstanding at Maturity
(February 23, 1998), the Company will pay $3,200,000. The Company presently
anticipates that the Notes Offering will be completed prior to September 25,
1997, and the proceeds thereof used, in part, to refinance the Bridge Loan,
and, accordingly, that none of the Maintenance Fee or other fees described in
this paragraph will be paid.
 
  The Bridge Loan matures on February 23, 1998 (181 days from funding). The
Bridge Loan bears interest at 5% over the Adjusted Eurodollar Rate, as defined
in the Bridge Loan.
 
  11. BACKGROUND OF THE OFFER; PURPOSE OF THE OFFER AND THE MERGER; THE
  MERGER AGREEMENT AND CERTAIN OTHER AGREEMENTS.
 
  The following description was prepared by Parent and the Company.
Information about the Company was provided by the Company and neither the
Purchaser nor Parent takes any responsibility for the accuracy or completeness
of any information regarding meetings or discussions in which Parent or its
representatives did not participate.
 
  BACKGROUND OF THE OFFER.
 
  In the fall of 1993, a representative of AIP Capital Fund was informed by a
representative of Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ")
of the Company's difficult financial condition and an introduction was
arranged with the then existing management of the Company. Following this
contact, American Industrial Partners Capital Fund, L.P. initiated a review of
certain publicly-available information concerning the Company with a view
toward a possible investment by American Industrial Partners Capital Fund,
L.P. in the Company.
 
  On November 12, 1993, American Industrial Partners Capital Fund, L.P.
entered into a confidentiality agreement with the Company pursuant to which
American Industrial Partners Capital Fund, L.P. agreed to treat as
confidential certain information provided to it by and on behalf of the
Company. Following the execution of
 
                                      17
<PAGE>
 
the confidentiality agreement, American Industrial Partners Capital Fund, L.P.
was provided with certain confidential information. Discussions between
certain representatives of American Industrial Partners Capital Fund, L.P.,
and representatives of the Company continued over the next several months. In
early 1994, American Industrial Partners Capital Fund, L.P. and the Company
mutually determined not to pursue an investment by American Industrial
Partners Capital Fund, L.P. in the Company at that time.
 
  During 1994 as the Company was attempting to negotiate a prepackaged plan of
reorganization with the Company's creditors (the "Chapter 11 Reorganization"),
additional discussions between American Industrial Partners Capital Fund, L.P.
and the Company occurred to explore any role that an investment by American
Industrial Partners Capital Fund, L.P. might play in the Chapter 11
Reorganization. Additionally, during the period of those discussions,
representatives of American Industrial Partners Capital Fund, L.P. met with a
representative of the Stockholder to discuss a possible sale of the
Stockholder's shares of Common Stock to American Industrial Partners Capital
Fund, L.P. Again, American Industrial Partners Capital Fund, L.P., the Company
and the Stockholder mutually determined not to pursue an investment by
American Industrial Partners Capital Fund, L.P. in the Company at that time.
 
  Since the completion of the Chapter 11 Reorganization in December 1994,
representatives of AIP Capital Fund have remained in casual contact with the
Company, principally through Joseph J. Radecki, Jr., Executive Vice President
of Jefferies & Company, Inc. ("Jefferies"), the Company's financial advisor,
and a director of the Company, and with the Stockholder, principally through
F. John Stark, III, Senior Vice President, General Counsel and portfolio
manager for the Special Investments Portfolio of PPM America, Inc. ("PPM"), an
affiliate of the Stockholder, and a Director of the Company. The Stockholder
has repeatedly advised the Company (as reported in the Company's periodic
reports and other filings with the Commission) that the Stockholder has from
time to time had discussions relating to disposition of all or a substantial
portion of its equity interest in the Company.
 
  Early in April 1997, the Company announced that it had reached an agreement
in principle to acquire Marion. On that date, Mr. Lawrence W. Ward, Jr., a
principal of AIP Capital Fund, a successor fund to American Industrial
Partners Capital Fund, L.P., contacted Mr. Stark and requested the opportunity
to speak with management to obtain additional information concerning the
Company and its prospects in light of the Marion Acquisition. During that
conversation, they also discussed a possible investment by AIP Capital Fund in
the Company for the purpose of assisting with the financing of the Marion
Acquisition. Although the Company informed AIP Capital Fund that no additional
equity investment would be necessary to complete the Marion Acquisition,
discussions among AIP Capital Fund, the Company and the Stockholder continued
over the next several weeks.
 
  Following a series of internal meetings over the next several months among
the members of AIP Capital Fund's management, AIP Capital Fund determined to
explore another possible investment in the Company. On July 1, 1997, Mr. Stark
and Mr. Willard R. Hildebrand, President, Chief Executive Officer and a
Director of the Company, met with Mr. Ward and Mr. Robert L. Purdum, a partner
of AIP Capital Fund. As a result of this meeting, the Company entered into a
new confidentiality agreement (the "Confidentiality Agreement") which
superseded the confidentiality agreement executed on November 12, 1993.
Pursuant to the terms of the Confidentiality Agreement, AIP Capital Fund
agreed for a period of three (3) years not to effect or propose, or assist a
third party to do the same, any business combination with restructuring or
recapitalization of, acquisition of any securities or assets of,
representation on the Board of Directors or otherwise seek to influence
control of the Company without the consent of the Board of Directors of the
Company. At the July 1 meeting, Mr. Stark requested that further negotiations,
if any, between AIP Capital Fund and the Company be held through Mr. Radecki
in his firm's role as financial advisor to the Company.
 
  Between July 1, 1997 and July 25, 1997, Mr. Radecki held several
conversations with representatives of AIP Capital Fund, including Messrs.
Ward, Rogers, also a partner of AIP Capital Fund, and Purdum. Topics discussed
included: how the Company might respond should AIP Capital Fund make an offer
for a portion or all of the Shares, AIP Capital Fund's history and manner of
acting with respect to other transactions it had completed, how a proposal
from AIP Capital Fund to purchase a portion or all of the Shares would affect
the pending Marion Acquisition and the then contemplated senior notes offering
and other matters.
 
                                      18
<PAGE>
 
  At subsequent meetings between representatives of AIP Capital Fund and
Company executives, held on July 24 and 25, 1997 at the Company's offices, the
discussions chiefly involved due diligence matters under the Confidentiality
Agreement. Additionally, Mr. Theodore C. Rogers was involved in these
discussions. AIP Capital Fund conducted its business due diligence
investigation of the Company with a view to submitting a proposal involving a
control transaction with the Company.
 
  On July 24, 1997, Mr. Ward telephoned Mr. Radecki to explore a possible
acquisition of the Stockholder's shares of the Company's Common Stock for a
price of $15.00 per Share. Mr. Radecki advised Mr. Ward that, although he did
not speak for the Stockholder (being the Company's financial advisor), it was
Mr. Radecki's understanding that, in light of the Marion Acquisition and a
then-contemplated senior notes offering, the Stockholder would not be
interested in selling its Shares for less than $18.00 per Share and that, in
any event, it was Mr. Radecki's further understanding that the Stockholder
would only endorse an offer which provided that the Stockholder would receive
the same consideration per Share as would all other holders of Shares.
 
  Thereafter, AIP Capital Fund requested an opportunity to conduct additional
due diligence with a view toward improving the value of its proposal for a
control transaction involving the Company. Following additional due diligence,
on the morning of July 27, 1997, Mr. Ward contacted Mr. Radecki to indicate
that AIP Capital Fund was prepared to submit a non-binding expression of
interest to acquire all of the issued and outstanding Common Stock of the
Company at a price equal to $17.00 per Share. In response, Mr. Radecki advised
Mr. Ward that a proposed offer at $17.00 per Share would not be acceptable to
either the Company or to the Stockholder.
 
  Subsequently, AIP Capital Fund considered a revised capital structure for
the Company which could be implemented in connection with a merger proposal.
Jefferies, after consulting with the other proposed placement agents of the
Senior notes offering that the Company was then considering in connection with
the Marion Acquisition, informed representatives of AIP Capital Fund that it
believed that $150 million of ten year senior subordinated securities could be
sold in connection with the acquisition of the Company by AIP Capital Fund or
an affiliate. Additionally, AIP Capital Fund was informed by the Company that
the previously negotiated $75 million secured revolving credit agreement could
be put in place in connection with a merger transaction.
 
  On the afternoon of July 28, 1997, Mr. Ward telephoned Mr. Radecki and made
the following proposal (the "Initial AIP Proposal"): AIP Capital Fund was
prepared to submit a letter of intent to acquire the Company at a price equal
to $18.00 per Share (the "Transaction Price"). The Initial AIP Proposal
provided that, concurrently with the execution of the merger agreement, the
Stockholder would execute and deliver to the Purchaser an agreement pursuant
to which the Stockholder would agree to tender all of the Shares held by it to
the Purchaser in the tender offer (if made) and to vote all such Shares in
favor of the merger, and granting to the Purchaser an option, exercisable in
certain circumstances and for a period to be negotiated, to purchase all of
such Shares at an exercise price equal to the Transaction Price. With respect
to the option, the Initial AIP Proposal also provided that in the event that
an entity other than the Purchaser acquired a majority of the outstanding
Shares at a price higher than the Transaction Price pursuant to an agreement
signed within such period, the Purchaser and the Stockholder would share 50/50
in the amount by which the price in such other acquisition exceeded the
Transaction Price. In addition, the Initial AIP Proposal provided that the
transaction would be subject to certain conditions, including, among others,
that the debt financing necessary to finance the transaction would be
available to the Purchaser on the terms previously disclosed to the Company
and that the acquisition of Marion by the Company would have been consummated.
The Initial AIP Proposal stated that the definitive merger agreement would
provide that in the event that the merger agreement were terminated due to
certain circumstances to be negotiated, the Purchaser would be entitled to a
termination fee of $7.0 million. The Initial AIP Proposal also provided that,
for a period of three weeks following acceptance of the Initial AIP Proposal
by the Company, the Company would negotiate with AIP Capital Fund on an
exclusive basis with respect to an acquisition transaction. AIP Capital Fund
also indicated that it was prepared to commit at least $140.0 million of its
own equity capital to finance the transaction, including the purchase of all
outstanding equity interests in the Company and the repayment of certain
existing Company indebtedness.
 
 
                                      19
<PAGE>
 
  On the morning of July 29, 1997, Mr. Radecki stated to Mr. Ward that the
Company had instructed Jefferies to seek certain additional favorable terms
from AIP Capital Fund. As a result of this conversation, and although not all
of the Company's proposed terms were accepted, AIP Capital Fund did agree to
increase its equity investment in the Merger.
 
  On the afternoon of July 29, 1997, AIP Capital Fund submitted a revised
proposal with certain additional terms (the "Revised AIP Proposal"),
including, among others, a provision which automatically terminated the
Revised AIP Proposal if the Company disclosed the existence of the Revised AIP
Proposal or its contents. The Revised AIP Proposal also included certain
material terms of a proposed Stockholder Agreement between AIP Capital Fund
and the Stockholder. The Company concluded that the confidentiality provision
in the Revised AIP Proposal was unacceptable. Mr. Radecki communicated this
position to Mr. Ward.
 
  Late in the afternoon of July 29, 1997, Mr. Ward contacted Mr. Radecki to
indicate that AIP Capital Fund was prepared to remove the confidentiality
provision from the Revised AIP Proposal, but insisted that the parties agree
that if within six months after the date of the proposed letter of intent, the
Company were to sign an agreement pursuant to which control of the Company or
a substantial part of its assets were acquired by a third party, then the
Company would reimburse AIP Capital Fund and its affiliates for their expenses
not exceeding $500,000 and would pay to AIP Capital Fund a fee of $1.0
million. On the evening of July 29, 1997, AIP Capital Fund submitted to the
Company a further revision to the Revised AIP Proposal (the "Final AIP
Proposal") embodying these terms.
 
  On July 30, 1997 Mr. Radecki communicated to Mr. Ward the Board of
Director's decision to accept the Final AIP Proposal and to formalize the
Company's acceptance of the Final AIP Proposal through execution of a letter
of intent (the "Letter of Intent"). Following additional negotiations
throughout the day on July 30 between representatives of AIP Capital Fund, the
Stockholder and the Company to finalize the Letter of Intent, attached to this
Schedule 14D-1 and incorporated herein by reference, the Company issued a
press release early on the morning of July 31, 1997 and filed the full text of
the Letter of Intent as an exhibit to the Company's Current Report on Form 8-K
dated August 1, 1997 (with a filing date of August 4, 1997). A copy of the
press release is attached to this Schedule 14D-1 and incorporated herein by
reference.
 
  Following the execution of the Letter of Intent, AIP Capital Fund, together
with its legal and other professional advisors, intensified its due diligence
investigation of the Company and its business. In addition, AIP Capital Fund
and its legal counsel held a number of discussions over the telephone with the
Company and the Stockholder and their respective legal counsel to negotiate
the various terms of the definitive agreements, including the Merger
Agreement, the Stockholder Agreement and the Guarantee. The parties also
simultaneously negotiated the terms of the settlement agreement entered into
between the Company and the Stockholder concurrently with the execution of the
Merger Agreement. See the Company's Schedule 14D-9 -- Joint Prosecution
Agreement.
 
  At a meeting of the Board of Directors of the Company held on August 19,
1997, the Board of Directors unanimously approved the Merger Agreement and the
transaction contemplated thereby including the Offer and the Merger and
determined that the terms of the Offer and the Merger are fair to, and in the
best interests of, the holders of the Common Stock, and unanimously recommend
that stockholders of the Company accept the Offer and tender their Shares. On
August 19, 1997, Jefferies delivered to the Company's Board of Directors its
opinion to the effect that the consideration to be received by the holders of
Common Stock pursuant to the Offer and under the terms of the Merger
Agreement, is fair to such holders, from a financial point of view. The
written opinion of Jefferies is set forth in full as an exhibit to the
Company's Schedule 14D-9 which is being mailed to stockholders of the Company.
Stockholders of the Company are urged to read that opinion in its entirety.
 
  Following the approval of the Board of Directors, on August 21, 1997,
Parent, the respective parties executed and delivered the Merger Agreement,
Guarantee and the Stockholder Agreement and issued a joint press release,
attached to this Schedule 14D-1 and incorporated herein by reference.
 
  On August 26, 1997, the Purchaser and Parent commenced the Offer.
 
                                      20
<PAGE>
 
PURPOSE OF THE OFFER AND THE MERGER
 
  The purpose of the Offer, the Merger and the Merger Agreement is to enable
Parent to acquire control of, and the entire equity interest in, the Company.
The Offer is being made pursuant to the Merger Agreement and is intended to
increase the likelihood that the Merger will be effected. The purpose of the
Merger is to acquire all outstanding Shares not purchased pursuant to the
Offer. The transaction is structured as a merger in order to ensure the
acquisition by Parent of all the outstanding Shares.
 
  If the Merger is consummated, Parent's common equity interest in the Company
would increase to 100% and Parent would be entitled to all benefits resulting
from that interest. These benefits include complete management with regard to
the future conduct of the Company's business and any increase in its value.
Similarly, Parent will also bear the risk of any losses incurred in the
operation of the Company and any decrease in the value of the Company.
 
  Stockholders of the Company who sell their Shares in the Offer will cease to
have any equity interest in the Company and to participate in its earnings and
any future growth. If the Merger is consummated, the stockholders will no
longer have an equity interest in the Company and instead will have only the
right to receive cash consideration pursuant to the Merger Agreement or to
exercise statutory appraisal rights under Delaware law. See Section 12.
Similarly, the stockholders of the Company will not bear the risk of any
decrease in the value of the Company after selling their Shares in the Offer
or the subsequent Merger.
 
  The primary benefits of the Offer and the Merger to the stockholders of the
Company are that such stockholders are being afforded an opportunity to sell
all of their Shares for cash at a price which represents a premium of
approximately 43% over the closing market price of the Common Stock on the
last full trading day prior to the initial public announcement that the
Company and AIP Capital Fund had executed a letter of intent regarding a
possible sale of the Company, and a more substantial premium over recent
historical trading prices.
 
THE MERGER AGREEMENT
 
  As of August, 21, 1997, Parent, the Purchaser and the Company entered into
the Merger Agreement, pursuant to which the Purchaser agreed to make the
Offer. The following description of the Merger Agreement does not purport to
be complete and is qualified by reference to the text of the Merger Agreement,
a copy of which is filed as Exhibit (c) (1) hereto and incorporated herein by
reference. Capitalized terms not otherwise defined herein have the meanings
set forth in the Merger Agreement. The Merger Agreement may be examined and
copies may be obtained at the places and in the manner set forth in Section 8
of this Offer to Purchase.
 
  The Offer. The Merger Agreement provides for the making of the Offer by the
Purchaser. The obligation of the Purchaser to accept for payment and pay for
Shares tendered is subject to there being tendered, and not withdrawn prior to
the expiration of the Offer, that number of Shares which represents at least
51% of the Shares then outstanding on a fully diluted basis (after giving
effect to the conversion or exercise of all outstanding options, warrants and
other rights and securities exercisable or convertible in Shares) (the
"Minimum Condition"), and to the satisfaction of the other conditions
described in Annex I to the Merger Agreement. The Merger Agreement provides
that the Purchaser may not amend or waive the Minimum Condition, decrease the
Offer Price or decrease the number of Shares sought or otherwise amend any
other condition of the Offer in any manner adverse to the holders of the
Shares without the prior written consent of the Company; provided, that the
Purchaser may, in its sole discretion, extend the expiration date of Offer so
long as the Purchaser expressly irrevocably waives any condition (other than
the Minimum Condition) that subsequently may not be satisfied during such
extension of the Offer.
 
  Designation of Directors. The Merger Agreement provides that, promptly after
the purchase of Shares pursuant to the Offer, Parent shall be entitled to
designate directors on the Board of Directors of the Company as will give
Parent representation proportionate to its ownership interest. To this end,
the Company has agreed to expand the size of the Board of Directors of the
Company or to seek the resignation of one or more of the current
 
                                      21
<PAGE>
 
directors, as requested by Parent. However, in the event that Parent's
designees are elected to the Board of Directors of the Company, and until the
Effective Time, the Board of Directors of the Company must include at least
one director who is a director as of the date of execution of the Merger
Agreement and who is neither an officer of the Company nor a designee,
stockholder, affiliate or associate of Parent (one or more of such directors
being the "Independent Directors"). If no Independent Directors remain, the
other directors shall designate one person to fill a vacancy created by
resignation of one or more directors, who is neither an officer of the Company
nor a designee, stockholder, affiliate or associate of the Purchaser, such
person so designated being deemed an Independent Director. The Company's
obligation to appoint Parent's designees to the Board of Directors of the
Company is subject to compliance with Section 14(f) of the Exchange Act and
Rule 14f-l promulgated thereunder. Following the election of Parent's
designees, any action to amend or terminate the Merger Agreement on behalf of
the Company, to exercise or waive any of the Company's rights, benefits or
remedies thereunder, to extend the time for the performance of the Purchaser's
obligations thereunder or to take other action by the Company under the Merger
Agreement shall be effected only by the action of a majority of the directors
of the Company then in office who are Independent Directors.
 
  The Merger. The Merger Agreement provides that, at the Effective Time and
until the Effective Time the Purchaser will be merged with and into the
Company, and the Company will continue as the Surviving Corporation. The
Merger will become effective at the time of filing with the Secretary of State
of the State of Delaware of a Certificate of Merger, or at such later time as
may be specified in the Certificate of Merger (the "Effective Time"). The
parties expect to file the Certificate of Merger as soon as practicable
following the closing of the Merger, which will take place on the second
business day after the conditions to the parties' obligation to effect the
Merger have been satisfied or waived, unless another date is otherwise agreed.
 
  Each Share issued and outstanding immediately prior to the Effective Time
(other than Shares with respect to which appraisal rights have been properly
exercised, and Canceled Shares (as defined below) shall be converted into the
right to receive the Offer Price . Each Share issued and outstanding
immediately prior to the Effective Time owned by Parent or the Purchaser, or
any subsidiary of the Company, Parent or the Purchaser, and each Share held in
the treasury of the Company (collectively, the "Canceled Share") immediately
prior to the Effective Time will be canceled and cease to exist. Each share of
Common Stock of the Purchaser issued and outstanding immediately prior to the
Effective Time will automatically be converted into one share of Common Stock
of the Surviving Corporation.
 
  The Merger Agreement provides that the Certificate of Incorporation and By-
laws of the Purchaser shall be the Certificate of Incorporation and By-laws of
the Surviving Corporation unless otherwise determined by the Purchaser prior
to the Effective Time. The Merger Agreement also provides that the directors
of the Purchaser at the Effective Time will be the directors of the Surviving
Corporation and that the officers of the Company at the Effective Time will be
the officers of the Surviving Corporation.
 
  The respective obligations of Parent and the Purchaser, on the one hand, and
the Company, on the other hand, to effect the Merger are subject to the
satisfaction on or prior to the Closing Date (as defined in the Merger
Agreement) of each of the following conditions: (i) Parent or the Purchaser or
their affiliates shall have made or cause to be made, the Offer and shall have
purchased Shares pursuant to the Offer, unless such failure to purchase is a
result of a breach of Parent's and the Purchaser's obligations under the
Merger Agreement, (ii) the Merger Agreement shall have been approved and
adopted by the requisite vote of the holders of Shares, if required by
applicable law, in order to consummate the Merger; (iii) no statute, rule or
regulation shall have been enacted or promulgated by any governmental
authority which prohibits the consummation of the Merger, and there shall be
no order or injunction of a court of competent jurisdiction in effect
precluding the consummation of the Merger and (iv) the applicable waiting
period under the HSR Act shall have expired or been terminated.
 
  Recommendation. The Company represents in the Merger Agreement that the
Board of Directors of the Company has (i) determined that each of the Merger
and the Offer is fair to the stockholders of the Company, and (ii) resolved to
recommend acceptance of the Offer and approval and adoption of the Merger
Agreement by
 
                                      22
<PAGE>
 
the Company's stockholders. The recommendation of the Board of Directors of
the Company may be withdrawn, modified or amended if the Board of Directors of
the Company determines in good faith, after receipt of a written opinion of
outside legal counsel to the Company, that the exercise of the director's
fiduciary duties requires such withdrawal, amendment or modification. The
Company has agreed to use its best efforts to file a
Solicitation/Recommendation Statement of Schedule 14D-9 containing such
recommendations with the Commission and to mail such Schedule 14D-9 to the
stockholders of the Company contemporaneous with the commencement of the
Offer.
 
  Stock Options and Stock Appreciation Rights. At or immediately prior to the
Effective Time, each outstanding option to purchase Shares (the "Options") and
each outstanding Stock Appreciation Right (the "SARs") granted under the
Company's Non-Employee Directors' Stock Option Plan and the 1996 Employees'
Stock Incentive Plan and any other stock-based incentive plan or arrangement
of the Company (collectively, the "Stock Plans") shall be canceled and, in
consideration of such cancellation, the holder of such Options and SARs shall
receive for each Share subject to such Option or SAR an amount (subject to
withholding taxes) equal to the product of (i) the excess, if any, of the
Offering Price over the exercise price of such Option or the per Share base
price of such SAR, as applicable, and (ii) the number of Shares subject to
such Option or SAR. The Company will obtain all necessary consents or releases
from holders of the Options or SAR to effect the foregoing. Upon receipt of
the Option Price, the Option will be cancelled. The surrender of an Option or
SAR to the Company will be deemed a release of any and all rights a holder had
or may have had in respect of such Option or SAR. Except as may be otherwise
agreed to by Parent or the Purchaser and the Company, the Company (i) shall
cause the Stock Plans to terminate as of the Effective Time, and (ii)
following the Effective Time, shall take all actions necessary to ensure that
no holder of Options or SARs or any participant in the Stock Plans shall have
any right thereunder to acquire any equity securities of the Company, the
Surviving Corporation or any subsidiary thereof.

the Merger Agreement not being satisfied, or would make many representation or
warranty of the Company contained therein inaccurate in any respect at, or as
of any time prior to, the Effective Time, or that would materially impair the
ability of the Company to consummate the Merger in accordance with the terms
of the Merger Agreement or materially delay such consummation; and (m) the
Company shall not enter into an agreement, contract, commitment or arrangement
to do any of the foregoing, or to authorize, recommend, propose or announce an
intention to do any of the foregoing.
 
  No Solicitation. In the Merger Agreement, the Company has agreed to notify
the Purchaser immediately if any proposals are received by, any information is
requested from, or any negotiations or discussions are sought
 
                                      24
<PAGE>
 
to be initiated or continued with the Company or its officers, directors,
employees, investment bankers, attorneys, accountants or other agents, in each
case in connection with any Takeover Proposal (as defined below) or the
possibility or consideration of making a Takeover Proposal ("Takeover Proposal
Interest") indicating, in connection with such notice, the name of the Person
indicating such Takeover Proposal Interest and the terms and conditions of any
proposals or offers. The Company has agreed that it will immediately cease and
cause to be terminated any existing activities, discussions or negotiations,
if any, with any parties conducted heretofore with respect to any Takeover
Proposal Interest. The Company has agreed that it shall keep the Parent
informed, on a current basis, of the status and terms of any Takeover Proposal
Interest. As used in the Merger Agreement, "Takeover Proposal" means any
tender or exchange offer involving the Company, any proposal for a merger,
consolidation or other business combination involving the Company, any
proposal or offer to acquire in any manner a substantial equity interest in,
or a substantial portion of the business or assets of, the Company (other than
immaterial or insubstantial assets or inventory in the ordinary course of
business or assets held for sale), any proposal or offer with respect to any
recapitalization or restructuring with respect to the Company or any proposal
or offer with respect to any other transaction similar to any of the foregoing
with respect to the Company other than the Marion Acquisition or pursuant to
the transactions to be effected pursuant to the Merger Agreement.
 
  In the Merger Agreement the Company agrees that it will not, and that it
will use its best efforts to ensure that its officers, directors, employees,
investment bankers, attorneys, accountants and other agents do not, directly
or indirectly: (i) initiate, solicit or encourage, or take any action to
facilitate the making of, any offer or proposal which constitutes or is
reasonably likely to lead to any Takeover Proposal, (ii) enter into any
agreement with respect to any Takeover Proposal, or (iii) in the event of an
unsolicited written Takeover Proposal for the Company, engage in negotiations
or discussions with, or provide any information or data to, any Person (other
than Parent, any of its affiliates or representatives and except for
information which has been previously publicly disseminated by the Company)
relating to any Takeover Proposal; provided however, that nothing contained in
the Merger Agreement shall prohibit the Company or the Board of Directors of
the Company from (i) taking and disclosing to the Company's stockholders a
position with respect to a tender or exchange offer by a third party pursuant
to Rules 14d-9 and 14e-2 promulgated under the Exchange Act, or (ii) taking
such action and disclosing to the Company's stockholders as the Board of
Directors of the Company may determine in good faith is required under
applicable law, after receipt of a written opinion from outside legal counsel,
to the Company that such disclosure is required under applicable law and the
failure to make such disclosure would likely cause the Board of Directors of
the Company to violate its fiduciary duties to the Company's stockholders
under applicable law. Notwithstanding the foregoing, prior to the acceptance
of Shares pursuant to the Offer, the Company may furnish information
concerning its business, properties or assets to any Person (as defined in the
Merger Agreement)
pursuant to terms substantially similar to those contained in the
Confidentiality Agreement, dated July 1, 1997, entered into between AIP
Capital Fund and the Company (the "Confidentiality Agreement") and may
negotiate and participate in discussions and negotiations with such Person
concerning a Takeover Proposal if (x) such person has on an unsolicited basis
submitted a bona fide written proposal to the Company relating to any such
transaction which the Company Board determines in good faith, after receiving
advice from Jefferies or another nationally recognized investment banking
firm, represents a superior transaction to the offer and the merger and (y) in
the opinion of the Board of Directors of the Company, only after receipt of a
written opinion from outside legal counsel to the Company to such effect, the
failure to provide such information or access or to engage in such discussions
or negotiations would likely cause the Board of Directors of the Company to
violate its fiduciary duties to the Company's stockholders under applicable
law (a Takeover proposal which satisfies clauses (x) and (y) being referred to
herein as a "Superior Proposal"). The Company shall promptly and in any event
within one business day following any determination by the Board of Directors
that a Takeover Proposal is a Superior Proposal, notify Parent of such
determination of the same and prior to providing any such party with any
material non-public information. The Company shall promptly provide to Parent
any material non-public information regarding the Company provided to any
other party which was not previously provided to Parent. At any time after two
business days following notification to Parent of the Company's intent to do
so (which notification shall include the identity of the bidder and the
material terms and conditions of the proposal) and if the Company has
otherwise complied with the terms referred to in the Merger Agreement, the
Board of Directors may
 
                                      25
<PAGE>
 
terminate the Merger Agreement and enter into an agreement with respect to a
Superior Proposal, provided that the Company shall, concurrently with entering
into such agreement, pay or cause to be paid to Parent the Termination Fee (as
hereinafter defined), plus any amount payable at the time for reimbursement of
expenses. Except as set forth above, neither the Board of Directors nor any
committee thereof shall (i) withdraw or modify, or propose to withdraw or
modify, in a manner adverse to Parent or the Purchaser, the approval or
recommendation by such Board of Directors or any such committee of the Offer,
the Merger Agreement or the Merger, (ii) approve or recommend or propose to
approve or recommend, any Takeover Proposal or (iii) enter into any agreement
with respect to any Takeover Proposal.
 
  Pursuant to the Merger Agreement, the Company has agreed to give Parent
reasonable access to its facilities, books and records, to permit Parent to
make such inspections as it may reasonably require and to cause its officers
to furnish Parent with such information as Parent may from time to time
reasonably request.
 
  Each of the Company, Parent and the Purchaser has agreed in the Merger
Agreement to use its best efforts to take, or cause to be taken, all things
necessary, proper or advisable to consummate the transactions contemplated by
the Merger Agreement. Each such party also has agreed to cooperate and use its
best efforts to make all filings and obtain all licenses, permits, consents,
approvals and other authorizations of third parties, including governmental
authorities, necessary to consummate such transactions, including the filings
required of the Parent or the Purchaser or any of their affiliates under the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act").
 
  Pursuant to the Merger Agreement, each of the Company, Parent and the
Purchaser has agreed not to make any public statement with respect to the
Merger Agreement of the transactions contemplated thereby without the prior
consent of the other parties. The parties thereto have also agreed that the
provisions of the Confidentiality Agreement would remain binding and in full
force and effect.
 
  Company Stockholder Meeting. If required by applicable law, the company has
agreed to: (i) hold a special meeting of its stockholders (the "Special
Meeting") as soon as practicable following acceptance for payment of Shares
pursuant to the Offer for the purpose of taking action upon the Merger
Agreement; (ii) prepare and file with the Commission a preliminary proxy
statement or information statement relating to the Merger Agreement and use
its best efforts to (a ) cause a definitive proxy statement (the "Proxy
Statement") to be mailed to its stockholders following acceptance for payment
of Shares pursuant to the Offer and (b) obtain the necessary approvals of the
Merger Agreement by its stockholders. Parent and the Purchaser have agreed to
vote all Shares owned by them in favor of approval of the Merger Agreement at
any such meeting. However, in the event that Parent or the Purchaser shall
acquire at least 90 percent of the outstanding Shares, the parties will, at
the request of Parent, take action to cause the Merger to become effective as
soon as practicable after such acquisition without a meeting of stockholders
of the Company in accordance with the Delaware General Corporation Law
("DGCL").
 
  Indemnification of Company Officers and Directors; Liability Insurance. In
the event of any threatened or actual claim, action, suit, proceeding or
investigation, whether civil, criminal or administrative, including, without
limitation, any such claim, action, suit, proceeding or investigation by or in
the right of the Company or any of its Subsidiaries, in which any of the
present or former officers or directors (the "Indemnified Parties") of the
Company or any of its Subsidiaries is, or is threatened to be, made a party by
reason of the fact that he or she is or was, prior to the Effective Time, a
director or officer of the Company or any of its Subsidiaries or is or was,
prior to the Effective Time, the Surviving Corporation shall indemnify and
hold harmless, as and to the full extent permitted by applicable law, each
such Indemnified Party against any losses, claims, damages, liabilities,
costs, expenses (including reasonable attorneys' fees and expenses), judgments
fines and amounts paid in settlement in connection with any such claim,
action, suit, proceeding or investigation. In the event of any such claim,
action, suit, proceeding or investigation (whether arising before or after the
Effective Time), (i) the Indemnified Parties may retain counsel satisfactory
to them (which counsel shall be reasonably satisfactory to the Company or the
Surviving Corporation), and the Company, or the Surviving Corporation after
the Effective Time, shall pay all reasonable fees and expenses of such counsel
for the Indemnified parties promptly as
 
                                      26
<PAGE>
 
statements therefor are received and (ii) the Company and the Surviving
Corporation will use their respective reasonable efforts to assist in the
vigorous defense of any such matter; provided, that neither the Company nor
the Surviving Corporation shall be liable for any settlement effected without
its prior written consent (which consent shall not be unreasonably withheld);
and provided further that the Surviving Corporation shall have no obligation
thereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall have
become final and non-appealable, that indemnification of such Indemnified
Party in the manner contemplated thereby is prohibited by applicable law. The
Indemnified Parties as a group may retain only one law firm to represent them
with respect to each such matter unless there is, under applicable standards
of professional conduct, a conflict of interest on any significant issue
between the positions of any two or more Indemnified parties, or any similar
impediment to the joint representation of multiple Indemnified parties by a
single law firm.
 
  The Merger Agreement provides that until the Effective Time the Company
shall keep in effect Section 7.7 of its By-Laws, and thereafter, for a period
of six years, the Surviving Corporation shall keep in effect in its By-Laws a
provision which provides for indemnification of the Indemnified Parties to the
extent permitted by the DGCL.
 
  The Merger Agreement also provides that Parent or the Surviving Corporation
shall maintain the Company's existing officers' and directors' liability
insurance ("D&O Insurance") for a period of not less than six years after the
Effective Time; provided, that Parent may substitute therefor policies of
substantially equivalent coverage and amounts containing terms no less
favorable to such former directors or officers; provided, further, if the
existing D&O Insurance expires, is terminated or canceled during such period,
Parent or the Surviving Corporation will use all reasonable efforts to obtain
substantially similar D&O Insurance; provided, further, however, that in no
event shall Parent be required to pay aggregate premiums for insurance in
excess of 150% of the average of the aggregate premiums paid by the Company in
1995, 1996 and 1997 (through the date of the Merger Agreement) on an
annualized basis for such purpose (the "Average Premium"); and provided,
further, that if Parent or the Surviving Corporation is unable to obtain the
amount of insurance required by the Merger Agreement for such aggregate
premium, Parent or the Surviving Corporation shall obtain as much insurance as
can be obtained for an annual premium not in excess of 150% of the Average
Premium.
 
  Representations and Warranties. The Merger Agreement contains various
representations and warranties of the parties thereto, including
representations by the Company as to, among other things, corporate existence
and good standing, capitalization, corporate authorization, financial
statements, public filings, conduct of business, consents and approvals,
reports, undisclosed liabilities, certain changes or events concerning its
businesses, compliance with applicable law, employee benefit plans,

supplier, licensee or customer of the Company has cancelled or otherwise
modified its relationship with the Company. In addition, Parent and the
Purchaser represented as to, among other things, corporate existence and good
standing, corporate authorization, consents and approvals, and the financing
commitments referred to in Section 4.5 of the Merger Agreement.

otherwise prohibiting the transactions contemplated by the Merger Agreement;
(iv) by Parent if, without any material breach by Parent or the Purchaser of
its obligations under the Merger Agreement, the purchase of Shares pursuant to
the Offer shall not have occurred on or before February 20, 1998; (v) by the
Company if, without any material breach by the Company of its obligations
under the Merger Agreement, the purchase of Shares pursuant to the Offer shall
not have occurred on or before February 20, 1998; (vi) by the Company (A) if
there shall be a material breach of any of Parent's of the Purchaser's

provisions thereof, including the notice provisions therein, and that it makes
simultaneous payment of the Termination Fee, plus any amounts then due as a
reimbursement of expenses; (vii) by Parent, if prior to the purchase of Shares
pursuant to the Offer, the Company shall have breached in any material respect
(without reference to any materially qualification contained therein) any

and (B) cannot be or has not been cured within thirty days of the receipt of
written notice thereof; (viii) by Parent, at any time prior to the purchase of

receipt or, if sooner, the date its existence first becomes publicly
disclosed, or (E) any Person or group (as defined in Section 13(d) (3) of the
Exchange Act) other than Parent or the Purchaser or any of their respective

15% of the outstanding Shares (either on a primary or a fully diluted basis);
provided, however, that this provision shall not apply to any Person that owns
more than 15% of the outstanding Shares on the date of the Merger Agreement;
provided, further, that such Person does not further increase its beneficial
ownership beyond the number of Shares such Person beneficially owns on the
date of the Merger Agreement.

                                      28
<PAGE>

STOCKHOLDER AGREEMENT
 
  The following is a summary of certain provisions of the Stockholder
Agreement. The summary is qualified in its entirety by reference to the
Stockholder Agreement which is incorporated herein by reference and a copy of
which has been filed with the Commission as Exhibit(C)(2) to the Schedule 14D-
1. The Stockholder Agreement may be examined and copies may be obtained at the
places and in the manner set forth in Section 8 of this Offer to Purchase.
 
  As a condition and inducement to Parent's and the Purchaser's entering into
the Merger Agreement and incurring the liabilities therein, concurrently with
the execution and delivery of the Merger Agreement, Jackson National Life
Insurance Company, a Michigan corporation (the "Stockholder"), which together
with PPM America, Inc., a Delaware corporation shares voting power and
dispositive power with respect to approximately 40% of the Shares, is entering
into a Stockholder Agreement (the "Stockholder Agreement"), dated as of August
21, 1997, with Parent and the Purchaser. In the Stockholder Agreement, the
Stockholder represented that it owns, in the aggregate, 4,228,382 Shares and
$63,963,000 in principal amount of the Company's 10.5% Secured Notes due
September 14, 1999 (the "Secured Notes"). The Stockholder has agreed that it
will not withdraw any Shares tendered into the Offer.
 
  In the Stockholder Agreement, the Stockholder agrees that it will tender its
Shares promptly into the Offer and that it will not withdraw any Shares so
tendered. The Purchaser agrees to purchase all of the Shares so tendered at
$18.00 per Share, or such higher price per Share as may be offered by the
Purchaser in the Offer, provided that the Purchaser's obligation to accept for
payment and pay for the Shares in the Offer is subject to all the terms and
conditions of the Offer set forth in the Merger Agreement and Annex I thereto.
 
  Pursuant to the Stockholder Agreement, the Stockholder has granted to the
Parent during the term of the Merger Agreement an irrevocable proxy to vote
its shares, or grant a consent or approval in respect of such Shares, in
connection with any meeting of the stockholders of the Company (i) in favor of
the Merger and (ii) against any action or agreement which would impede,
interfere with or prevent the Merger, including any other extraordinary
corporate transaction such as a merger, reorganization or liquidation
involving the Company and a third party or any other proposal by a third party
to acquire the Company.
 
                                      29

  During the term of the Stockholder Agreement, the Stockholder has agreed
that it will not (subject to certain exceptions) (i) transfer, or enter into
any contract, option, agreement or other understanding with respect to the
transfer of, its Shares or the Secured Notes held by it or any interest
therein, (ii) except as provided in the Stockholder Agreement, grant any
proxy, power of attorney or other authorization or consent in or with respect
to its Shares or Secured Notes, (iii) deposit its Shares or Secured Notes in
any voting trust or enter into any voting agreement or arrangement with
respect to such Shares or Secured Notes, or (iv) take any other action with
respect to its Shares or Secured Notes that would in any way restrict, limit
or interfere with the performance of its obligations pursuant to the
Stockholder Agreement; provided, however, that the Stockholder may transfer
all or a portion of its Shares or Secured Notes to a person or entity who, by
written instrument reasonably acceptable in form and substance to the Parent,
agrees to be bound by each of the terms of the Merger Agreement. In addition,
the Stockholder, Parent and the Purchaser have agreed that (i) the Stockholder
will notify the Purchaser of any inquiry the Stockholder receives which might
lead to an acquisition of the Company by a third party; and (ii) the
Stockholder will waive, if requested, the provisions of the Indenture (as
defined in the Stockholder Agreement) relating to the prior notice of
redemption of the Secured Notes, or will, immediately following consummation
of the Senior Notes Offering (as hereinafter defined) and subject to being
indemnified by Parent and Purchaser, sell its Secured Notes to the Company at
face value plus accrued interest from June 30, 1997 through the date of
purchase.
 
  Termination of the Stockholder Agreement. The Stockholder Agreement shall
terminate upon the earlier of (a) the date (the "Termination Date") that is
six months following the date upon which the Merger Agreement is terminated in
accordance with its terms, or (b) the Effective Time, provided that certain
provisions specified in the Stockholder Agreement will survive such
termination. Neither party has any other unilateral right to terminate the
Stockholder Agreement.
 
  Purchase Option. In the Stockholder Agreement, the Stockholder grants to
Parent an irrevocable option (the "JNL Option") to purchase the Shares at a
purchase price of $18.00 per Share (the "Exercise Price"). At any time or from
time to time prior to the Termination Date, Parent (or its designee) may
exercise the JNL Option, in whole or in part, if on or after the date thereof
any Third Party (as defined therein) shall have taken certain defined steps
that could evidence, lead to or result in the acquisition of or exercise of
control over the Company. Notwithstanding any other provision of the
Stockholder Agreement, in the event that the Merger Agreement is terminated
and at any time prior to the Termination Date a person other than Parent or
any of its affiliates acquires a majority of the outstanding Shares at a price
higher than the Exercise Price (an "Alternative Transaction"), then Parent
shall promptly either reduce the number of Shares subject to the JNL Option,
pay cash to the Stockholder or do both such that the actual Total Profit
realized or to be realized by Parent upon the consummation of an Alternative
Transaction does not exceed 50% of the Total Profit that Parent would
otherwise realize had it not taken the foregoing actions; provided, that in
the event that the Parent elects to reduce the number of Shares subject to the
JNL Option, there shall be pending, at the time the Parent makes such
election, a transaction involving the Company that, if consummated, would
allow the Stockholder to dispose of any remaining Shares that would not
otherwise be purchased by Parent upon the exercise of the JNL Option. As used
in the Stockholder Agreement, the term "Total Profit" shall mean the aggregate
amount (before taxes) of the net cash amounts and the fair market value (as
reasonably determined by Parent) of all other forms of consideration received
or to be received by the Parent pursuant to the sale of the aggregate number
of Shares subject to the JNL Option (or any other securities into which such
Shares are converted or exchanged) in any Alternative Transaction, less the
aggregate Exercise Price of all of such Shares. In the event that Parent or
the Purchaser pays a price higher than $18.00 per Share for shares tendered
into the Offer, the Exercise Price shall be increased to equal such higher
price.

                                      30

  As an inducement to the Company's entering into the Merger Agreement,
concurrently with the execution and delivery of the Merger Agreement, American
Industrial Partners Capital Fund II, L.P. ("AIP Capital Fund") and the Company
have entered into a Guarantee, dated as of August 21, 1997 (the "Guarantee").
Pursuant to the Guarantee, among other things, AIP Capital Fund has agreed
unconditionally and irrevocably, for the benefit of the Company the
performance of all obligations of Parent and the Purchaser pursuant to the
Merger Agreement; provided that the aggregate liability to which AIP Capital
Fund may become subject pursuant to the Guarantee or otherwise in connection
with the transactions contemplated by the Merger Agreement will not in any
event exceed $7 million. The Guarantee terminates upon the earliest of (i) the
consummation of the Merger, (ii) October 7, 2004 or (iii) the performance of
all obligations of Parent and the Purchaser pursuant to the Merger Agreement.
 
CONFIDENTIALITY AGREEMENT
 
  The following is a summary of certain provisions of the Confidentiality
Agreement, dated July 1, 1997 between the Company and AIP Capital Fund. The
following summary of the Confidentiality Agreement does not purport to be
complete and is qualified by reference to the text of the Confidentiality
Agreement, a copy of which is filed as Exhibit (c) (4) hereto and incorporated
herein by reference.
 
  The Confidentiality Agreement contains customary provisions pursuant to
which, among other matters, AIP Capital Fund has agreed to keep confidential
all nonpublic, confidential or proprietary information furnished to it by the
Company relating to the Company subject to certain exceptions (the
"Confidential Information"), and to use the Confidential Information solely in
connection with the certain future business agreements relating to the
Company.
 
  12. PLANS FOR THE COMPANY; OTHER MATTERS.
 
  Plans for the Company. Parent is conducting a detailed review of the Company
and its assets, corporate structure, dividend policy, capitalization,
operations, properties, policies, management and personnel and will consider,
subject to the terms of the Merger Agreement, what, if any, changes would be
desirable in light of the circumstances which exist upon completion of the
Offer. Such changes could include changes in the Company's business, corporate
structure, certificate of incorporation, by-laws, capitalization, Board of
Directors, management or dividend policy, although, except as disclosed in
this Offer to Purchase, Parent has no current plans with respect to any of
such matters. The Merger Agreement provides that, promptly after the purchase
by the Purchaser of any Shares pursuant to the Offer, Parent has the right to
designate such number of directors, rounded up to the next whole number, on
the Company's Board of Directors as is equal to the product of the total
number of directors on the Company's Board of Directors (giving effect to the
directors designated by Parent) multiplied by the percentage that the number
of Shares beneficially owned by the Purchaser or any affiliate of the
Purchaser (including such Shares as are accepted for payment pursuant to the
Offer) bears to the total number of Shares then outstanding. See Section 11.
The Merger Agreement provides that the directors of the Purchaser and the
officers of the Company at the Effective Time of the Merger will, from and
after the Effective Time, be the initial directors and officers, respectively,
of the Surviving Corporation.
 
  Except as disclosed in this Offer to Purchase, neither Parent nor the
Purchaser has any present plans or proposals that would result in an
extraordinary corporate transaction, such as a merger, reorganization,
liquidation, relocation of operations, or sale or transfer of assets,
involving the Company or any of its subsidiaries, or any material changes in
the Company's corporate structure, business or composition of its management
or personnel.
 
OTHER MATTERS
 
  Stockholder Approval. Under the DGCL, the approval of the Board of Directors
of the Company and the affirmative vote of the holders of a majority of the
outstanding Shares are required to adopt and approve the Merger Agreement and
the transactions contemplated thereby. The Company has represented in the
Merger
 
                                      31
<PAGE>
 
Agreement that the execution and delivery of the Merger Agreement by the
Company and the consummation by the Company of the transactions contemplated
by the Merger Agreement have been duly authorized by all necessary corporate
action on the part of the Company, subject to the approval of the Merger by
the Company's stockholders in accordance with the DGCL. In addition, the
Company has represented that the affirmative vote of the holders of a majority
of the outstanding shares of Common Stock is the only vote of the holders of
any class or series of the Company's capital stock which is necessary to
approve the Merger Agreement and the transactions contemplated thereby,
including the Merger. Therefore, unless the Merger is consummated pursuant to
the short-form merger provisions under the DGCL described below (in which case
no further corporate action by the stockholders of the Company will be
required to complete the Merger), the only remaining required corporate action
of the Company will be the approval of the Merger Agreement and the
transactions contemplated thereby by the affirmative vote of the holders of a
majority of the shares of Common Stock. The Merger Agreement provides that
Parent will vote, or cause to be voted, all of the Shares then owned by
Parent, the Purchaser or any of Parent's other subsidiaries and affiliates in
favor of the approval of the Merger and the adoption of the Merger Agreement.
In the event that Parent, the Purchaser and Parent's other subsidiaries
acquire in the aggregate at least a majority of the shares of Common Stock,
the vote of no other stockholder of the Company will be required to approve
the Merger and the Merger Agreement.
 
  Short-Form Merger. Section 253 of the DGCL provides that, if a corporation
owns at least 90% of the outstanding shares of each class of another
corporation, the corporation holding such stock may merge such other
corporation into itself without any action or vote on the part of the board of
directors or the stockholders of such other corporation (a "short-form
merger"). In the event that Parent, the Purchaser and any other subsidiaries
of Parent acquire in the aggregate at least 90% of the outstanding shares of
Common Stock, pursuant to the Offer or otherwise, then, at the election of
Parent, a short-form merger could be effected without any approval of the
Board of Directors or the stockholders of the Company, subject to compliance
with the provisions of Section 253 of the DGCL. Even if Parent and the
Purchaser do not own 90% of the outstanding shares of Common Stock following
consummation of the Offer, Parent and the Purchaser could seek to purchase
additional shares in the open market or otherwise in order to reach the 90%
threshold and employ a short-form merger. The per share consideration paid for
any Shares so acquired may be greater or less than that paid in the Offer.
Parent presently intends to effect a short-form merger if permitted to do so
under the DGCL.
 
DELAWARE BUSINESS COMBINATION STATUTE.
 
  Section 203. Section 203, in general, prohibits a Delaware corporation such
as the Company, from engaging in a "Business Combination" (defined as a
variety of transactions, including mergers, as set forth below) with an
"Interested Stockholder" (defined generally as a person that is the beneficial
owner of 15% or more of a corporation's outstanding voting stock) for a period
of three years following the date that such person became an Interested
Stockholder unless (a) prior to the date such person became an Interested
Stockholder, the board of directors of the corporation approved either the
Business Combination or the transaction that resulted in the stockholder
becoming an Interested Stockholder, (b) upon consummation of the transaction
that resulted in the stockholder becoming an Interested Stockholder, the
Interested Stockholder owned at least 85% of the voting stock of the
corporation outstanding at the time the transaction commenced, excluding stock
held by directors who are also officers of the corporation and employee stock
ownership plans that do not provide employees with the right to determine
confidentially whether shares held subject to the plan will be tendered in a
tender or exchange offer or (c) on or subsequent to the date such person
became an Interested Stockholder, the Business Combination is approved by the
board of directors of the corporation and authorized at a meeting of
stockholders, and not by written consent, by the affirmative vote of the
holders of a least 66 2/3% of the outstanding voting stock of the corporation
not owned by the Interested Stockholder.
 
  Under Section 203, the restrictions described above do not apply if, among
other things (a) the corporation's original certificate of incorporation
contains a provision expressly electing not to be governed by Section 203; (b)
the corporation, by action of its stockholders, adopts an amendment to its
certificate of incorporation or by-laws expressly electing not to be governed
by Section 203, provided that, in addition to any other vote required by law,
such amendment of the certificate of incorporation or by-laws must be approved
by the affirmative vote
 
                                      32
<PAGE>
 
of a majority of the shares entitled to vote, which amendment would not be
effective until 12 months after the adoption of such amendment and would not
apply to any Business Combination between the corporation and any person who
became an Interested Stockholder of the corporation on or prior to the date of
such adoption; (c) the corporation does not have a class of voting stock that
is (1) listed on a national securities exchange, (2) authorized for quotation
on an inter-dealer quotation system of a registered national securities
association or (3) held of record by more than 2,000 stockholders, unless any
of the foregoing results from action taken, directly or indirectly, by an
Interested Stockholder or from a transaction in which a person became an
Interested Stockholder; or (d) a stockholder become an Interested Stockholder
"inadvertently" and thereafter divests itself of a sufficient number of shares
so that such stockholder ceases to be an Interested Stockholder. Under Section
203, the restrictions described above also do not apply to certain Business
Combinations proposed by an Interested Stockholder following the announcement
or notification or one of certain extraordinary transactions involving the
corporation and a person who had not been an Interested Stockholder during the
previous three years or who became an Interested Stockholder with the approval
of a majority of the corporation's directors.
 
  Section 203 provides that, during such three-year period, the corporation
may not merge or consolidate with an Interested Stockholder or any affiliate
or associate thereof, and also may not engage in certain other transactions
with an Interested Stockholder or any affiliate or associate thereof,
including, without limitation, (a) any sale, lease, exchange, mortgage,
pledge, transfer or other disposition of assets (except proportionately as a
stockholder of the corporation) having an aggregate market value equal to 10%
or more of the aggregate market value of all assets of the corporation
determined on a consolidated basis or the aggregate market value of all the
outstanding stock of a corporation; (b) any transaction which results in the
issuance or transfer by the corporation or by certain subsidiaries thereof of
any stock of the corporation or such subsidiaries to the Interested
Stockholder, except pursuant to a transaction which effects a pro rata
distribution to all stockholders of the corporation; (c) any transaction
involving the corporation or certain subsidiaries thereof which has the effect
of increasing the proportionate share of the stock of any class or series, or
securities convertible into the stock of any class or series, of the
corporation or any such subsidiary which is owned directly or indirectly by
the Interested Stockholder (except as a result of immaterial changes due to
fractional share adjustments); or (d) any receipt of the Interested
Stockholder of the benefit (except proportionately as a stockholder of such
corporation) of any loans, advances, guarantees, pledges or other financial
benefits provided by or through the corporation.
 
  The Company has represented in the Merger Agreement that the provisions of
Section 203 of the DGCL are not applicable to any of the transactions
contemplated by the Merger Agreement, including the Merger and the purchase of
Shares in the Offer.
 
  Appraisal Rights. Holders of the Shares do not have appraisal rights as a
result of the Offer. However, if the Merger is consummated, holders of the
Shares at the effective time of the Merger will have certain rights pursuant
to the provisions of Section 262 of the DGCL. Dissenting stockholders of the
Company who comply with the applicable statutory procedures will be entitled
to receive a judicial determination of the fair value of their Shares
(exclusive of any element of value arising from the accomplishment or
expectation of the Merger) and to receive payment of such fair value in cash,
together with a fair rate of interest thereon, if any. Any such judicial
determination of the fair value of the Shares could be based upon factors
other than, or in addition to, the price per share of Common Stock, as the
case may be, to be paid in the Merger or the market value of the Shares. The
value so determined could be more or less than the price per Share to be paid
in the Merger.
 
  THE FOREGOING SUMMARY OF THE RIGHTS OF DISSENTING STOCKHOLDERS DOES NOT
PURPORT TO BE A COMPLETE STATEMENT OF THE PROCEDURES TO BE FOLLOWED BY
STOCKHOLDERS DESIRING TO EXERCISE ANY AVAILABLE DISSENTERS' RIGHTS. THE
PRESERVATION AND EXERCISE OF DISSENTERS' RIGHTS REQUIRE STRICT ADHERENCE TO
THE APPLICABLE PROVISIONS OF THE DGCL.
 
  The foregoing description of the DGCL, including the descriptions of
Sections 203 and 262, is not necessarily complete and is qualified in its
entirety by reference to the DGCL.
 
 
                                      33
<PAGE>
 
  Rule 13e-3. The Merger would have to comply with any applicable federal law
operative at the time. Rule 13e-3 under the Exchange Act is applicable to
certain "going private" transactions; however, the Purchaser believes that
Rule 13e-3 will not be applicable to the Merger. If Rule 13e-3 were applicable
to the Merger, it would require, 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 a transaction, be filed with the Commission and disclosed
to minority stockholders prior to consummation of the transaction.
 
  13. DIVIDENDS AND DISTRIBUTIONS.
 
  The Merger Agreement provides that neither the Company nor any of its
Subsidiaries shall: (i) declare, set aside or pay any dividend or other
distribution payable in cash, stock or property with respect to its capital
stock; (ii) issue, sell, pledge, dispose of or encumber any additional shares
of, or securities convertible into or exchangeable for, or options, warrants,
calls, commitments or rights of any kind to acquire (or stock appreciation
rights with respect to), any shares of capital stock of any class of the
Company or its Subsidiaries, other than Shares reserved for issuance on the
date hereof pursuant to the exercise of Options or with respect to SARs
outstanding on the date hereof; or (iii) redeem, purchase or otherwise
acquire, directly or indirectly, any of its capital stock.
 
  14. CONDITIONS OF THE OFFER.
 
  Notwithstanding any other provisions of the Offer, and in addition to (and
not in limitation of) the Purchaser's rights to extend and amend the Offer at
any time in its sole discretion (subject to the provisions of the Merger
Agreement), the Purchaser shall not be required to accept for payment or,
subject to any applicable rules and regulations of the Commission, including
Rule 14e-l(c) under the Exchange Act (relating to the Purchaser's obligation
to pay for or return tendered Shares promptly after termination or withdrawal
of the Offer), pay for, and may delay the acceptance for payment of or,
subject to the restriction referred to above, the payment for, any tendered
Shares, and may terminate or amend the Offer as to any Shares not then paid
for, if (i) the Debt Financing shall not have been received and be immediately
available in the full amounts and on the terms and in accordance with the
conditions set forth in the "highly confident" letter from a nationally-

  by any Governmental Entity against the Purchaser, Parent, the Company or

  material limitations on Parent's or the Purchaser's ownership or operation
  (or that of any of their respective Subsidiaries or affiliates) of all or a
  material portion of their or the Company's businesses or assets, or to
  compel Parent or the Purchaser or their respective Subsidiaries and
  affiliates to dispose of or hold separate any material portion of the
  business or assets of the Company or Parent and their respective
  Subsidiaries, in each case taken as a whole, (ii) challenging the
  acquisition by Parent or the Purchaser of any Shares under the Offer,
  seeking to restrain or prohibit the making or consummation of the Offer or
  the Merger or the performance of any of the other transactions contemplated
  by the Merger Agreement, or seeking to obtain from the Company, Parent or
  the Purchaser any damages that are material in relation to the Company and
  its Subsidiaries taken as a whole, (iii) seeking to impose material
  limitations on the ability of the Purchaser, or render the Purchaser
  unable, to accept for payment, pay for or purchase some or all of the

  exercise full rights of ownership of the Shares, including, without
  limitation, the right to vote the Shares purchased by it on all matters
  properly presented to the Company's shareholders, or (v) which otherwise is
  reasonably likely to have a Company Material Adverse Effect (as defined in
  the Merger Agreement);

  Entity, to the Offer or the Merger, or any other action shall be taken by
  any Governmental Entity, other than the application to the Offer or the

  likely to result, directly or indirectly, in any of the consequences
  referred to in clauses (i) through (v) of paragraph (a) above;
 
    (c) there shall have occurred (i) any general suspension of trading in,
  or limitation on prices for, securities on the New York Stock Exchange, the

  ability of financial institutions in the United States to extend credit or
  syndicate loans or (vi) in the case of any of the foregoing existing at the

  thereof;

  Effect;
 
    (e) (i) the Board of Directors of the Company or any committee thereof

  representations and warranties, as of the date of the Merger Agreement and
  as of the scheduled expiration of the Offer (provided that for purposes of
  this paragraph (f), other than the representation and warranty of the
  Company set forth in Section 3.26 of the Merger Agreement, the
  representations and warranties of the Company set forth in the Merger
  Agreement shall not be deemed to have been made with respect to the
  Business of the Marion Sellers (as the term "Business" is defined in the
  Marion Agreement) or any of the assets acquired or liabilities assumed
  thereunder;
 
    (g) the Company shall have failed to perform any obligation or to comply
  with any agreement or covenant to be performed or complied with by it under
  the Merger Agreement;
 
    (h) the Purchaser shall have failed to receive a certificate executed by
  the President or a Vice President of the Company, dated as of the scheduled

<PAGE>
 
    (k) there shall have occurred any change (or any development that,
  insofar as reasonably can be foreseen, is or could reasonably be expected
  to result in any change) that is materially adverse to the business,
  operations, properties (including intangible properties), condition
  (financial or otherwise), results of operations, assets, liabilities or
  prospects of the Business (as the term "Business" is defined in the Marion
  Agreement) of the Marion Sellers (as defined in the Marion Agreement);
 
    (l) the Secured Notes Indenture (as defined in the Merger Agreement)
  shall not have been fully satisfied and discharged pursuant to the terms
  thereof, and all collateral securing the Secured Notes shall not have been
  released (unless the Secured Notes Indenture Trustee has delivered to the
  Company a written agreement providing for the release of such collateral),
  subject only to the receipt by the Secured Notes Indenture Trustee of funds
  (pursuant to the Debt Financing) sufficient to effect the redemption of the
  Secured Notes;
 
    (m) JNL shall not have waived the right to at least 30 days prior notice
  of redemption provided by Section 1105 of the Secured Notes Indenture,
  pursuant to Section 106 of the Secured Notes Indenture (unless JNL shall
  have entered into a binding agreement with the Company to sell all of the
  Secured Notes held by JNL to the Company, at no more than par, at a time
  designated by the Company and acceptable to the Purchaser);
 
    (n) any Person or group (as defined in Section 13(d)(3) of the Exchange
  Act) other than Parent or the Purchaser or any of their respective
  subsidiaries or affiliates shall have become the beneficial owner (as
  defined in Rule 13d-3 promulgated under the Exchange Act) of more than 15%
  of the outstanding Shares (either on a primary or a fully diluted basis);
  provided, however, that this provision shall not apply to any Person that
  beneficially owns more than 15% of the outstanding Shares on the date
  hereof; provided, further, that such Person does not further increase its
  beneficial ownership beyond the number of Shares such Person beneficially
  owns on the date hereof; or
 
    (o) the Merger Agreement shall have been terminated in accordance with
  its terms.
 
  The foregoing conditions are for the sole benefit of Parent and the
Purchaser, may be asserted by Parent or the Purchaser regardless of the
circumstances giving rise to such condition (including any action or inaction
by Parent or the Purchaser) and may be waived by Parent or the Purchaser in
whole or in part at any time and from time to time in the sole discretion of
Parent or the Purchaser, subject in each case to the terms of the Merger
Agreement. The failure by Parent or the Purchaser at any time to exercise any
of the foregoing rights shall not be deemed a waiver of any such right and
each such right shall be deemed an ongoing right which may be asserted at any
time and from time to time.
 
  15. CERTAIN LEGAL MATTERS.
 
  Except as described in this Section 15, based on information provided by the
Company, none of the Company, Purchaser or Parent is aware of any license or
regulatory permit that appears to be material to the business of the Company
that might be adversely affected by the Purchaser's acquisition of Shares as
contemplated herein or of any approval or other action by a domestic or
foreign governmental, administrative or regulatory agency or authority that
would be required for the acquisition and ownership of the Shares by the
Purchaser as contemplated herein. Should any such approval or other action be
required, the Purchaser and Parent presently contemplate that such approval or
other action will be sought, except as described below under "State Takeover
Laws." While, except as otherwise described in this Offer to Purchase, the
Purchaser does not presently intend to delay the acceptance for payment of or
payment for Shares tendered pursuant to the Offer pending the outcome of any
such matter, there can be no assurance that any such approval or other action,
if needed, would be obtained or would be obtained without substantial
conditions or that failure to obtain any such approval or other action might
not result in consequences adverse to the Company's business or that certain
parts of the Company's business might not have to be disposed of or other

approval or other action. If certain types of adverse action are taken with
respect to the matters discussed below, the Purchaser could decline to accept
for payment or pay for any Shares tendered. See Section 14 for certain
conditions to the Offer, including conditions with respect to governmental
actions.
 
  State Takeover Laws. The Company conducts business in a number of other
states throughout the United States, some of which have enacted takeover laws
and regulations. Neither Parent nor the Purchaser knows whether any or all of
these takeover laws and regulations will by their terms apply to the Offer,
and, except as set forth above with respect to Section 203 of the DGCL and
below with respect to Chapter 552 of the Wisconsin Statutes, neither Parent
nor the Purchaser has currently complied with any other state takeover statute
or regulation. The Purchaser reserves the right to challenge the applicability
or validity of any state law purportedly applicable to the Offer and nothing
in this Offer to Purchase or any action taken in connection with the Offer,
including compliance with certain provisions of Chapter 552 of the Wisconsin
Statutes, is intended as a waiver of such right. If it is asserted that any
state takeover statute is applicable to the Offer and an appropriate court
does not determine that it is inapplicable or invalid as applied to the Offer,
the Purchaser might be required to file certain information with, or to
receive approvals from, the relevant state authorities, and the Purchaser
might be unable to accept for payment or pay for Shares tendered pursuant to
the Offer, or may be delayed in consummating the Offer. In such case, the
Purchaser may not be obligated to accept for payment or pay for any Shares
tendered pursuant to the Offer. See Section 14.
 
  Wisconsin Corporate Take-Over Law. Although the Company is organized under
the laws of the state of Delaware, the Wisconsin Corporate Take-Over Law,
Chapter 552 of the Wisconsin Statutes (the "Corporate Take-Over Law") may be
applicable to the Company if the Company satisfies all of the elements of the
definition of a "target company" thereunder. The Offer may constitute a "Take-
Over Offer" within the meaning of the Corporate Take-Over Law.
 
  The provisions of the Corporate Take-Over Law that may be applicable to the
Offer include the following: (i) a requirement that the Purchaser file
solicitation materials with the Wisconsin Department of Financial
Institutions -- Division of Securities (the "Division") at the same time they
are first used in the Offer; (ii) a prohibition against the dissemination of
false and misleading solicitation materials (with the Division having the
authority to prohibit the use of any such materials); (iii) a general
prohibition against fraudulent and deceptive practices in connection with the
Offer; (iv) a prohibition against the sale of the Shares to the Purchaser by a
controlling person of the Company for consideration higher than that paid to
other offerees; (v) a prohibition against the refusal by the Company to fail
to cooperate with the Purchaser in certain respects; and (vi) a prohibition
against the acquisition by a broker-dealer of any Shares on behalf of the
Purchaser or the Company unless certain prior filings are made with the
Division.
 
  Antitrust. Under the provisions of the HSR Act applicable to the Offer, the
acquisition of Shares under the Offer may be consummated only following the
expiration or early termination of the applicable waiting period under the HSR
Act.
 
  Under the provisions of the HSR Act applicable to the purchase of Shares
pursuant to the Offer, such purchase may not be made until the expiration of a
15-calendar day waiting period following the required filing of a Notification
Report Form under the HSR Act by AIP Capital Fund, which AIP Capital Fund
expects to submit on or before September 2, 1997. Accordingly, if the
Notification and Report Form is filed on or before September 3, 1997, the
waiting period under the HSR Act would expire at 11:59 P.M., New York City
time, on the fifteenth day after such filing, unless early termination of the
waiting period is granted by the FTC and the Department of Justice, Antitrust
Division (the "Antitrust Division") or AIP Capital Fund receives a request for
additional information or documentary material prior thereto. If either the
FTC or the Antitrust Division issues a request for additional information or
documentary material from AIP Capital Fund prior to the expiration of the 15-
day waiting period, the waiting period will be extended and will expire at
11:59 P.M., New York City time, on the tenth calendar day after the date of
substantial compliance by AIP Capital Fund with such request unless terminated
earlier by the FTC and the Antitrust Division. If such a request is issued,
the purchase of and payment
 
                                      37
<PAGE>
 
for Shares pursuant to the Offer will be deferred until the additional waiting
period expires or is terminated. Only one extension of such waiting period
pursuant to a request for additional information or documentary material is
authorized by the rules promulgated under the HSR Act. Thereafter, the waiting
period can be extended only by court order. Although the Company is required
to file certain information and documentary material with the Antitrust
Division and the FTC in connection with the Offer, neither the Company's
failure to make such filings nor a request to the Company from the Antitrust
Division or the FTC for additional information or documentary material will
extend the waiting period.
 
  The Antitrust Division and the FTC frequently scrutinize the legality under
the antitrust laws of transactions such as the Purchaser's proposed
acquisition of the Company. At any time before or after the Purchaser'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 Purchaser or the divestiture of
substantial assets of the Company or its subsidiaries or AIP Capital Fund or
its subsidiaries. Private parties and states attorneys general may also bring
legal action under the antitrust laws under certain circumstances. There can
be no assurance that a challenge to the Offer on antitrust grounds will not be
made, or, if such a challenge is made, of the result thereof. See Section 15.
 
  If the Antitrust Division, the FTC, a state or a private party raises
antitrust concerns in connection with a proposed transaction, the Purchaser
may engage in negotiations with the relevant governmental agency or party
concerning possible means of addressing these issues and may delay
consummation of the Offer or the Merger while such discussions are ongoing.
Both AIP Capital Fund and the Company have agreed to use their respective best
efforts to resolve any antitrust issues.
 
  Other Foreign Laws. The Company and some of its subsidiaries conduct
business in foreign jurisdictions, where regulatory filings or approvals may
be required or desirable in connection with the consummation of the Offer.
Certain of such filings or approvals, if required or desirable, may not be
made or obtained prior to the expiration of the Offer. After commencement of
the Offer, the Purchaser will seek further information regarding the
applicability of any such laws and intends to take such action as may be
required or desirable. See Section 14 for certain conditions to the Offer,
including conditions with respect to litigation and certain governmental
actions.
 
  Federal Reserve Board Regulations. Regulations G, U and X (the "Margin
Regulations") of the Federal Reserve Board restrict the extension or
maintenance of credit for the purpose of buying or carrying margin stock,
including the Shares, if the credit is secured directly or indirectly by
margin stock. Such secured credit may not be extended or maintained in an
amount that exceeds the maximum loan value of all the direct and indirect
collateral securing the credit, including margin stock and other collateral.
All financing for the Offer will be structured so as to be in full compliance
with the Margin Regulations.
 
  16. FEES AND EXPENSES.
 
  The Purchaser has retained MacKenzie Partners, Inc. to act as the
Information Agent and American Stock Transfer & Trust Company to act as the
Depositary in connection with the Offer. Such firms each will receive
reasonable and customary compensation for their services. The Purchaser has
also agreed to reimburse each such firm for certain reasonable out-of-pocket
expenses and to indemnify each such firm against certain liabilities in
connection with their services, including certain liabilities under federal
securities laws.
 
  The Purchaser will not pay any fees or commissions to any broker or dealer
or other person (other than the Information Agent) for making solicitations or
recommendations in connection with the Offer. Brokers, dealers, banks and
trust companies will be reimbursed by the Purchaser for customary mailing and
handling expenses incurred by them in forwarding material to their customers.

  17. MISCELLANEOUS.
 
  The Offer is being made to all holders of Shares other than the Company. The
Purchaser is not aware of any jurisdiction in which the making of the Offer or
the tender of Shares in connection therewith would not be in compliance with
the laws of such jurisdiction. If the Purchaser becomes aware of any
jurisdiction in which the making of the Offer would not be in compliance with
applicable law, the Purchaser will make a good faith effort to comply with any
such law. If, after such good faith effort, the Purchaser cannot comply with
any such law, the Offer will not be made to (nor will tenders be accepted from
or on behalf of) the holders of Shares residing in such jurisdiction. In 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 Purchaser 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 to make any
representation on behalf of Parent or the Purchaser not contained herein or in
the Letter of Transmittal and, if given or made, such information or
representation must not be relied upon as having been authorized.
 
  The Purchaser, Parent and AIP Capital Fund have filed with the Commission
the Schedule 14D-1 pursuant to Rule 14d-3 under the Exchange Act furnishing
certain additional information with respect to the Offer. The Schedule 14D-1
and any amendments thereto, including exhibits, may be examined and copies may

set forth in Section 8 of this Offer to Purchase (except that they will not be
available at the regional offices of the Commission).

of attorney being deemed to be an irrevocable power coupled with an interest),
to (a) deliver certificates for such Shares and all Distributions, or transfer
ownership of such Shares and all Distributions on the account books maintained
by a Book-Entry Transfer Facility, together, in any such case, with all
accompanying evidences of transfer and authenticity, to or upon the order of
the Offeror, upon receipt by the Depositary, as the undersigned's agent, of

Purchase), (b) present such Shares and all Distributions for cancellation and
transfer on the Company's books and (c) receive all benefits and otherwise

  The undersigned hereby represents and warrants that the undersigned has full
power and authority to tender, sell, assign and transfer the tendered Shares
and all Distributions and that, when the same are accepted for payment by the
Offeror, the Offeror will acquire good, marketable and unencumbered title

to complete the sale, assignment and transfer of the tendered Shares and all
Distributions. In addition, the undersigned shall promptly remit and transfer
to the Depositary for the account of the Offeror any such Distributions issued
to the undersigned, in respect of the tendered Shares, accompanied by
documentation of transfer, and pending such remittance or appropriate
assurance thereof, the Offeror shall be entitled to all rights and privileges
as owner of any such Distributions and, subject to the terms of the Agreement
and Plan of Merger, dated as of August 21, 1997, by and among Parent, the
Offeror and the Company, may withhold the entire purchase price or deduct from
the purchase price the amount or value thereof, as determined by the Offeror,
in its sole discretion.
 
  All authority conferred or agreed to be conferred in this Letter of
Transmittal shall be binding upon the successors, assigns, heirs, executors,
administrators and legal representatives of the undersigned and shall not be
affected by, and shall survive, the death or incapacity of the undersigned.
Except as stated in the Offer to Purchase, this tender is irrevocable.
 
  The undersigned hereby irrevocably appoints Lawrence W. Ward, Jr. or Kim A.

such attorney and proxy or his or her substitute shall in his or her sole
discretion deem proper, to execute any written consent concerning any matter
as each such attorney and proxy or his or her substitute shall in his or her
sole discretion deem proper with respect to, and to otherwise act with respect
to, all the Shares tendered hereby which have been accepted for payment by the

subsequent powers of attorney or proxies may be given by the undersigned (and,
if given, will not be deemed effective). The Offeror reserves the right to
require that, in order for Shares to be deemed validly tendered, immediately
upon the Offeror's acceptance for payment of such Shares, the Offeror must be
able to exercise full voting and other rights with respect to such Shares,
including voting at any stockholders meeting then scheduled.

conditions of the Offer. The undersigned recognizes that under certain
circumstances set forth in the Offer to Purchase, the Offeror may not be
required to accept for payment any of the tendered Shares. The Offeror's

of corporations or others acting in a fiduciary or representative capacity,
such persons should so indicate when signing, and proper evidence satisfactory
to the Offeror of their authority so to act must be submitted.
 
  When this Letter of Transmittal is signed by the registered owner(s) of the
Shares listed and tendered hereby, no endorsements of Share Certificates or
separate stock powers are required unless payment or Share Certificates
evidencing Shares not tendered or not accepted for payment are to be issued in
the name of a person other than the registered holder(s), in which case the
Share Certificate(s) evidencing the Shares tendered hereby must be endorsed or
accompanied by appropriate stock powers, in either case signed exactly as the
name(s) of the registered holder(s) appear(s) or such Share Certificate(s).
Signatures on such Share Certificate(s) or stock powers must be guaranteed by

  6. STOCK TRANSFER TAXES. Except as set forth in this Instruction 6, the
Offeror will pay, or cause to be paid, any stock transfer taxes with respect
to the transfer and sale of Shares to it or its assignee pursuant to the
Offer. If, however, payment of the purchase price of any Shares is to be made
to, or if Share Certificates evidencing Shares not tendered or accepted for
payment are to be issued in the name of, a person other than the registered
holder(s), or if tendered Shares Certificates are registered in the name of a
person other than the person(s) signing this Letter of Transmittal, the amount
of any stock transfer taxes (whether imposed on the registered holder(s) or
such person or otherwise payable on the account of the transfer to such other
person will be deducted from the purchase price of such Shares purchased,
unless evidence satisfactory to the Offeror of the payment of such taxes, or
exemption therefrom, is submitted. Except as provided in this Instruction 6,
it will not be necessary for transfer tax stamps to be affixed to the Share
Certificates evidencing the Shares tendered hereby.
 
  7. SPECIAL PAYMENT AND DELIVERY INSTRUCTIONS. If a check is to be issued in
the name of and/or Shares Certificates not accepted for payment are to be
returned to a person other than the signer of this Letter of Transmittal or if
a check is to be sent and/or such Share Certificates are to be returned to a
person other than the signer of this Letter of Transmittal or to an address
other than that shown in the box entitled "Description of Shares Tendered" on
the reverse hereof, the appropriate
 
                                       7
<PAGE>
 
boxes on the reverse side of this Letter of Transmittal should be completed.
Any stockholder tendering Shares by book-entry transfer will have any Shares
not accepted for payment returned by crediting the account maintained by such
stockholder at a Book-Entry Transfer Facility from which such transfer was
made.
 
  8. WAIVER OF CONDITIONS. Except as otherwise provided in the Offer to
Purchase, the Offeror reserves the absolute right, in its sole discretion, to
waive any of the conditions of the Offer or any defect or irregularity in the
tender of any Shares of any particular stockholder, whether or not similar
defects or irregularities are waived in the case of other stockholders.
 
  9. SUBSTITUTE FORM W-9. The tendering stockholder (or other payee) is
required, unless an exemption applies, to provide the Depositary with a
correct Taxpayer Identification Number ("TIN"), generally the stockholder's
social security or federal employer identification number, and with certain
other information, on Substitute Form W-9, which is provided under "Important
Tax Information" below, and to certify under penalties of perjury, that such
number is correct and that the stockholder (or other payee) is not subject to
backup withholding. If a tendering stockholder is subject to backup
withholding, he or she must cross out item (2) of the Certification Box on
Substitute Form W-9 before signing such Form. Failure to furnish the correct
TIN on the Substitute Form W-9 may subject the tendering stockholder (or other
payee) to a $50 penalty imposed by the Internal Revenue Service and payments
of cash to the tendering stockholder (or other payee) pursuant to the Offer
may be subject to backup withholding of 31%. If the tendering stockholder has
not been issued a TIN and has applied for a number or intends to apply for a
number in the near future, he or she should write "Applied For" in the space
provided for the TIN in Part I, sign and date the Substitute Form W-9 and sign
and date the Certificate of Awaiting Taxpayer Identification Number. If
"Applied For" is written in Part I and the Depositary is not provided with a
TIN by the time of payment, the Depositary will withhold 31% of all such
payments for surrendered Shares thereafter until a TIN is provided to the
Depositary.
 
  10. LOST OR DESTROYED CERTIFICATES. If any Share Certificate(s) has (have)
been lost or destroyed, the stockholder should check the appropriate box on
the reverse side of the Letter of Transmittal. The Company's stock transfer
agent will then instruct such stockholder as to the procedure to be followed
in order to replace the Share Certificate(s). The stockholder will have to
post a surety bond of approximately 2% of the current market value of the
stock. This Letter of Transmittal and related documents cannot be processed
until procedures for replacing lost or destroyed Share Certificates have been
followed.
 
  11. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES. Questions and requests for
assistance or additional copies of the Offer to Purchase, the Letter of
Transmittal, the Notice of Guaranteed Delivery and the Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 may be
directed to the Information Agent at the locations and telephone numbers set
forth below.
 
  IMPORTANT: THIS LETTER OF TRANSMITTAL (OR A FACSIMILE COPY THEREOF),
TOGETHER WITH ANY REQUIRED SIGNATURE GUARANTEES, OR IN THE CASE OF A BOOK-
ENTRY TRANSFER, AN AGENT'S MESSAGE, AND SHARE CERTIFICATES, OR A BOOK-ENTRY
CONFIRMATION, FOR SHARES AND ALL OTHER REQUIRED DOCUMENTS MUST BE RECEIVED BY
THE DEPOSITARY, OR THE NOTICE OF GUARANTEED DELIVERY (OR A FACSIMILE COPY
THEREOF) MUST BE RECEIVED BY THE DEPOSITARY, ON OR PRIOR TO THE EXPIRATION
DATE.
 
                           IMPORTANT TAX INFORMATION
 
  Under federal income tax law, a stockholder surrendering Shares must, unless
an exemption applies, provide the Depositary (as payor) with his correct TIN
on Substitute Form W-9 included in this Letter of Transmittal. If the
stockholder is an individual, his TIN is such stockholder's social security
number. If the correct TIN is not provided, the stockholder may be subject to
a $50 penalty imposed by the Internal Revenue Service and payments of cash to
the tendering stockholder (or other payee) pursuant to the Offer may be
subject to backup withholding of 31% of all payments of the purchase price.
 
  Certain stockholders (including, among others, all corporations and certain
foreign individuals and entities) are not subject to backup withholding. In
order for an exempt foreign stockholder to avoid backup withholding, such
person should complete, sign and submit a Form W-8, Certificate of Foreign
Status, signed under penalties of perjury, attesting to his
 
                                       8
<PAGE>
 
exempt status. A Form W-8 can be obtained from the Depositary. Exempt
stockholders, other than foreign stockholders, should furnish their TIN, write
"Exempt" on the face of the Substitute Form W-9 and sign, date and return the
Substitute Form W-9 to the Depositary. See the enclosed "Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9" for
additional instructions.
 
  If backup withholding applies, the Depositary is required to withhold 31% of
any payment made to payee. Backup withholding is not an additional tax.
Rather, the federal income 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 from
the Internal Revenue Service.
 
PURPOSE OF SUBSTITUTE FORM W-9
 
  To prevent backup withholding on payments that are made to a stockholder
with respect to Shares purchased pursuant to the Offer, the stockholder is
required to notify the Depositary of his correct TIN (or the TIN of any other
payee) by completing the Substitute Form W-9 included in this Letter of
Transmittal certifying (1) that the TIN provided on the Substitute Form W-9 is
correct (or that such stockholder is awaiting a TIN), and that (2) the
stockholder is not subject to backup withholding because (i) the stockholder
has not been notified by the Internal Revenue Service that the stockholder is
subject to backup withholding as a result of a failure to report all interest
and dividends or (ii) the Internal Revenue Service has notified the
stockholder that the stockholder is no longer subject to backup withholding.
 
WHAT NUMBER TO GIVE THE DEPOSITARY
 
  The stockholder is required to give the Depositary the TIN, generally the
social security number or employer identification number, of the record holder
of the Shares tendered hereby. If the Shares are in more than one name or are
not in the name of the actual owner, consult the enclosed Guidelines for
Certification of Taxpayer Identification Number on Substitute Form W-9 for
additional guidance on which number to report. If the tendering stockholder
has not been issued a TIN and has applied for a number or intends to apply for
a number in the near future, he or she should write "Applied For" in the space
provided for the TIN in Part I, sign and date the Substitute Form W-9 and sign
and date the Certificate of Awaiting Taxpayer Identification Number, which
appears in a separate box below the Substitute Form W-9. If "Applied For" is
written in Part I and the Depositary is not provided with a TIN by the time of
payment, the Depositary will withhold 31% of all payments of the purchase
price until a TIN is provided to the Depositary.

                                    PAGE 2
OBTAINING A NUMBER
If you do not have a taxpayer identification number or you do not know your
number, obtain form SS-5, Application for a Social Security Number Card (for
resident individuals), Form SS-4, Application for Employer Identification
Number (for businesses and all other entitites), for Form W-7 for
International Taxpayer Identification Number (for alien individuals required
to file U.S. tax returns), at an office of the Social Security Administration
or the Internal Revenue Service.
 To complete Substitute Form W-9, if you do not have a taxpayer identification
number, write "Applied For" in the space for the taxpayer identification
number in Part I, sign and date the Form, and give it to the requester.
Generally, you will then have 60 days to obtain a taxpayer identification
number and furnish it to the requester. If the requester does not receive your
taxpayer identification number within 60 days, backup withholding, if
applicable, will begin and will continue until you furnish your taxpayer
identification number to the requester.

dividends, and certain other payments to a payee who does not furnish a
taxpayer identification number to a payer. Certain penalties may also apply.

the related Letter of Transmittal and is being made to all holders of Shares.
The Offer is not being made to (nor will tenders be accepted from or on behalf
of) holders of Shares in any jurisdiction in which the making of the Offer or
the acceptance thereof would not be in compliance with the laws of such
jurisdiction or any administrative or judicial action pursuant thereto. In any

                   A CORPORATION FORMED AT THE DIRECTION OF
              AMERICAN INDUSTRIAL PARTNERS, CAPITAL FUND II, L.P.
 
  Bucyrus Acquisition Corp., a Delaware corporation (the "Purchaser") and a
wholly owned subsidiary of American Industrial Partners Acquisition Company,
LLC, a Delaware limited liability company ("AIP"), is offering to purchase all
of the issued and outstanding shares (the "Shares") of common stock, par value
$.01 per share (the "Common Stock"), of Bucyrus International, Inc., a
Delaware corporation (the "Company") for $18.00 per Share (the "Offer Price"),
net to the seller in cash, upon the terms and subject to the conditions set
forth in 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 TUESDAY, SEPTEMBER 23, 1997, UNLESS THE OFFER IS EXTENDED.
- --------------------------------------------------------------------------------
 
  The Offer is being made pursuant to an Agreement and Plan of Merger, dated
as of August 21, 1997 (the "Merger Agreement"), by and among AIP, the
Purchaser and the Company pursuant to which, as soon as practicable after the
completion of the Offer and satisfaction or waiver, if permissible, of all
conditions to the Merger (as defined below), the Purchaser will be merged with
and into the Company and the separate corporate existence of the Purchaser
will thereupon cease. The merger, as effected pursuant to the immediately
preceding sentence, is referred to herein as the "Merger," and the Company as
the surviving corporation of the Merger is sometimes herein referred to as the
"Surviving Corporation." At the effective time of the Merger (the "Effective
Time"), each share of Common Stock then outstanding (other than Shares held by
AIP or the Purchaser and Shares held by stockholders who perfect their
dissenters' rights under Delaware law) will be cancelled and extinguished and
converted into the right to receive the Offer Price or any higher price per
Share paid in the Offer, in cash payable to the holder thereof without
interest.
 
  THE BOARD OF DIRECTORS OF THE COMPANY HAS UNANIMOUSLY APPROVED THE MERGER
AGREEMENT AND THE TRANSACTIONS CONTEMPLATED THEREBY, INCLUDING THE OFFER AND
THE MERGER, AND DETERMINED THAT THE TERMS OF THE OFFER AND THE MERGER ARE FAIR
TO, AND IN THE BEST INTERESTS OF, THE HOLDERS OF THE COMMON STOCK, AND
UNANIMOUSLY RECOMMENDS THAT STOCKHOLDERS ACCEPT THE OFFER AND TENDER THEIR
SHARES.
<PAGE>
 
  THE OFFER IS CONDITIONED UPON, AMONG OTHER THINGS, (I) THERE BEING VALIDLY
TENDERED AND NOT WITHDRAWN PRIOR TO THE EXPIRATION OF THE OFFER, THAT NUMBER
OF SHARES OF COMMON STOCK WHICH REPRESENTS AT LEAST FIFTY-ONE PERCENT (51%) OF
THE SHARES OUTSTANDING ON A FULLY DILUTED BASIS (THE "MINIMUM CONDITION") AND
(II) THE RECEIPT AND IMMEDIATE AVAILABILITY OF FINANCING SUFFICIENT IN AMOUNT
TO ENABLE THE PURCHASER TO CONSUMMATE THE OFFER AND THE MERGER AND TO
REFINANCE CERTAIN INDEBTEDNESS FOR BORROWED MONEY OF THE COMPANY AND TO PAY
RELATED FEES AND EXPENSES. As used herein "fully diluted basis" takes into
account the conversion or exercise of all outstanding options and other rights
and securities exercisable or convertible into shares of Common Stock.
 
  As a condition and inducement to AIP's and the Purchaser's entering into the
Merger Agreement and incurring the liabilities therein, Jackson National Life
Insurance Company, a Michigan corporation (the "Stockholder"), which together
with PPM America, Inc., a Delaware corporation shares voting power and
dispositive power with respect to 4,228,382 Shares, concurrently with the
execution and delivery of the Merger Agreement are entering into a Stockholder
Agreement (the "Stockholder Agreement"), dated as of August 21, 1997, with AIP
and the Purchaser. Pursuant to the Stockholder Agreement, the Stockholder has
agreed, among other things, to tender the Shares held by it in the Offer, and
to grant AIP a proxy with respect to the voting of such Shares in favor of the
Merger and to grant Parent an option (the "JNL Option") with respect to such
Shares upon the terms and subject to the conditions set forth therein. The JNL
Option can only be exercised in certain circumstances as described in Section
11 of the Offer to Purchase.
 
  For purposes of the Offer, the Purchaser will be deemed to have accepted for
payment, and thereby purchased, Shares properly tendered to the Purchaser and
not withdrawn as, if and when the Purchaser gives oral or written notice to
American Stock Transfer & Trust Company (the "Depositary") of the Purchaser's
acceptance for payment of such Shares. Upon the terms and subject to the
conditions of the Offer, payment for Shares accepted for payment pursuant to
the Offer will be made by deposit of the purchase price therefor with the
Depositary, which will act as agent for tendering stockholders for the purpose
of receiving payment from the Purchaser and transmitting payment to tendering
stockholders. In all cases, payment for Shares accepted for payment pursuant
to the Offer will be made only after timely receipt by the Depositary of (i)
certificates for such Shares (or a timely Book-Entry Confirmation (as defined
in the Offer to Purchase) with respect thereto), (ii) a Letter of Transmittal
(or facsimile thereof), properly completed and duly executed, with any
required signature guarantees, or, in the case of a book-entry transfer, an
Agent's Message (as defined in the Offer to Purchase) and (iii) any other
documents required by the Letter of Transmittal. The per Share consideration
paid to any holder of Common Stock pursuant to the Offer will be the highest
per Share consideration paid to any other holder of such Shares pursuant to
the Offer. UNDER NO CIRCUMSTANCES WILL INTEREST BE PAID ON THE PURCHASE PRICE
TO BE PAID BY THE PURCHASER FOR THE SHARES, REGARDLESS OF ANY EXTENSION OF THE
OFFER OR ANY DELAY IN MAKING SUCH PAYMENT.
 
  Except as otherwise provided below, tenders of Shares are irrevocable.
Shares tendered pursuant to the Offer may be withdrawn pursuant to the
procedures set forth below at any time prior to the Expiration Date (as
defined in the Offer to Purchase) and, unless theretofore accepted for payment
and paid for by the Purchaser pursuant to the Offer, may also be withdrawn at
any time after September 23, 1997.
 
  For a withdrawal to be effective, a written, telegraphic 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 and
must specify the name of the person having tendered the Shares to be
withdrawn, the number of Shares to be withdrawn and the name of the registered
holder of the Shares to be withdrawn, if different from the name of the person
who tendered the Shares. If certificates for Shares 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 Section 3 of the Offer to Purchase), the
signatures on the notice of withdrawal must be guaranteed by
 
                                       2
<PAGE>
 
an Eligible Institution. If Shares have been delivered pursuant to the
procedures for book-entry transfer as set forth in Section 3 of the Offer to
Purchase, any notice of withdrawal must also specify the name and number of
the account at the appropriate Book-Entry Transfer Facility (as defined in the
Offer to Purchase) to be credited with the withdrawn Shares and otherwise
comply with such Book-Entry Transfer Facility's procedures. Withdrawals of
tenders of Shares may not be rescinded, and any Shares properly withdrawn will
thereafter be deemed not validly tendered for purposes of the Offer. However,
withdrawn Shares may be retendered by again following one of the procedures
described in Section 3 of the Offer to Purchase any time prior to the
Expiration Date.
 
  All questions as to the form and validity (including time of receipt) of
notices of withdrawal will be determined by the Purchaser, in its sole
discretion, which determination will be final and binding. None of the
Purchaser, AIP, 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.
 
  Subject to the terms of the Merger Agreement, the Purchaser expressly
reserves the right, in its sole discretion, at any time or from time to time,
to extend the period of time during which the Offer is open and thereby delay
acceptance for payment of, and the payment for, any Shares, by giving oral or
written notice of such extension to the Depositary.
 
  The information required to be disclosed by paragraph (e)(1)(vii) of Rule
14d-6 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 the Purchaser with the Company's stockholder lists
and security position list-ings for the purpose of disseminating the Offer to
holders of Shares. The Offer to Purchase, the related Letter of Transmittal
and other relevant documents will be mailed by the Purchaser to record holders
of Shares, and will be furnished by the Purchaser to brokers, dealers, banks,
trust companies and similar person 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 LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION AND SHOULD BE READ IN THEIR ENTIRETY BEFORE ANY DECISION IS MADE
WITH RESPECT TO THE OFFER.
 
  Questions and requests for assistance or additional copies of the Offer to
Purchase, Letter of Transmittal and other tender offer documents may be
directed to the Information Agent, at the address and telephone numbers set
forth below, and copies will be furnished at the Purchaser's expense. The
Purchaser will not pay any fees or commissions to any broker or dealer or
other person (other than the Information Agent) for soliciting tenders of
Shares pursuant to the Offer.

Dear Ladies and Gentlemen,

        We understand that American Industrial Partners Acquisition Company,
LLC, a Delaware limited liability company ("Parent") and Bucyrus Acquisition
Corp., a Delaware corporation (the "Purchaser") which is a wholly-owned
subsidiary of Parent, have offered to enter into an Agreement and Plan of Merger
(the "Merger Agreement") with Bucyrus International, Inc. ("Bucyrus" or the
"Company") pursuant to which, subject to the terms and conditions therein set
forth, (i) the Purchaser will make a cash tender offer (the "Tender Offer") to
acquire any and all shares of the issued and outstanding stock, $.01 par value,
of the Company (the "Common Shares") for $18.00 per share (the "Offer Price")
and (ii) the Purchaser will be merged with and into the Company and the issued
and outstanding Common Shares (except Dissenting Shares, as defined in the
Merger Agreement, and Common Shares held in the treasury of the Company or owned
by the Purchaser of any direct or indirect wholly owned subsidiary of the
Purchaser) will be canceled and extinguished and converted into the right to
receive the Offer Price in cash (the "Merger" and, with the Tender Offer, the
"Transaction").

        You asked us to render our opinion as to whether the Offer Price is
fair, from a financial point of view, to the holders of Common Shares.

        It is understood that we are not opining as to the fairness of the
transactions contemplated by the Stockholder Agreement referred to in the Merger
Agreement or any consideration under such Stockholder Agreement or any rights or
obligations of the persons identified as the Major Stockholders therein. Our
opinion is directed only to the fairness of the Offer Price to be received by
the holders of Common Shares in the Transaction.

        Jefferies & Company, Inc. ("Jefferies"), as part of its investment
banking business, is regularly engaged in the evaluation of capital structures
and the rendering of advice in financial restructurings and recapitalizations.
In addition, Jefferies performs valuations of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
biddings, secondary distributions of listed and unlisted securities, private
placements, financial restructurings and other financial services. Jefferies has
received a retainer and a fee for providing this opinion in connection with its
engagement as financial advisor to the

Company and will receive a success fee upon consummation of the Transaction. In 
addition, Jefferies will be compensated for services relating to the Company's 
acquisition of assets of The Marion Power Shovel Company and the placement of 
senior notes. In addition to delivering its opinion, Jefferies has actively
assisted the Companying in obtaining and negotiating the terms of the
Transaction. Joseph J. Radecki, Jr., an Executive Vice President of Jefferies,
is currently a member of the Board of Directors of Bucyrus. Mr. Radecki has
abstained from voting on any matters pertaining to the approval of the
Transaction by the Board of Directors, and intends to abstain from voting on
such matters in the future.

        In the connection with our opinion, we have reviewed a draft copy of the
Agreement dated August 15, 1997 and related exhibits thereto and certain
financial and other information that was publicly available or furnished to us
by Bucyrus, including certain internal financial analyses, financial forecasts,
pro forma financial information reports and other information prepared by
management of Bucyrus. We have also discussed with representatives of management
of Bucyrus the business, properties and prospects of Bucyrus and undertaken
other reviews, analyses and inquiries relating to Bucyrus as we have deemed
appropriate.

        In our review and analysis and in rendering this opinion, we have relied
upon, and have not independently verified, the accuracy, completeness and fair 
presentation of all financial  and other information (including financial 
projections, pro forma financial information, and estimates) that were provided 
to us by or on behalf of Bucyrus, or which were publicly available, and this 
opinion is conditioned upon such information (whether written or oral) being 
complete, accurate and fair in all material respects. With regard to the 
historical financial information, we have relied upon the opinion, issued by 
the Company's independent public accountants, in connection with the Company's 
audited financial statements. With respect to the above noted projected and pro
forma financial information, we have assumed, with your permission and without 
independent verification, that such information has been reasonably prepared 
on bases reasonably reflecting management's best currently available estimates 
and good faith judgments as to the future performance of Bucyrus and that 
Bucyrus will perform in accordance with such projections for all periods 
specified therein. We have not made an independent evaluation or appraisal or
conducted a physical inspection of any of the assets of Bucyrus, nor have we
been furnished with any such appraisals. Our opinion is based on economic,
monetary, political, market, and other conditions existing and which can be
evaluated as of the date of this opinion; however, such conditions are subject
to rapid and unpredictable change. We have assumed, with your permission, that
all consents, authorizations and agreements of other parties necessary to
consummate the Transaction have been, or will be, obtained without material
expense. Our opinion is addressed solely to the fairness of the Offer Price,
from a financial point of view, in the Transaction to the holders of the Common
Shares on the assumption that the Company and its Board of Directors have
determined that, from the standpoint of its business and prospects, it is
appropriate and desirable to consummate the Transaction and the other
transactions and agreements contemplated by the Agreement. Our opinion does not
address the relative merits of the Transaction as compared to any alternative
business transactions that might be available to the Company.

        In conducting our analysis and arriving at our opinion as expressed 
herein, we have considered such financial and other factors as we have deemed 
appropriate under the circumstances, including, among others: (i) the terms and 
business and financial aspects of the Transaction; (ii) the historical and 
current markets for the Company's common stock and for other securities of 
certain companies believed by Jefferies to be comparable to the Company; (iii) 
certain of the Company's operating and financial information, including 
projections and pro forma financial statements provided by management relating 
to the Company's business and prospects; (iv) publicly available financial data 
and stock market performance data of Bucyrus and other public companies which 
Jefferies deemed generally comparable to the Company; (v) publicly available 
financial data on certain merger and acquisition transactions; (vi) the 
Agreement and related exhibits and schedules (which we have assumed, with your 
permission, were delivered to us in substantially final form); and (vii) the 
Company's Annual Reports to Shareholders and Annual Reports on Form 10-K for the
fiscal years ended on December 31, 1995 and 1996, and its Quarterly Report on 
Form 10-Q for the period ended June 30, 1997.

        Our advisory services and the opinion set forth in this letter are 
provided for the information and assistance of the Board of Directors of the 
Company in connection with its consideration of the Transaction, and such 
opinion does not constitute a recommendation as to whether any holder of Common 
Shares should tender Common Shares pursuant to the Tender Offer or as to how any
such holder should vote with respect to the Merger.

        Based upon and subject to the foregoing, and based upon such other
matters as we consider relevant, it is our opinion as investment bankers that,
as of the date hereof, the Offer Price to be paid in the Transaction is fair,
from a financial point of view, to the holders of Common Shares.


                                                Sincerely,

                                                /s/ JEFFERIES & COMPANY, INC.

Re:  Senior Secured Revolving Credit Facility

Dear Sirs:

You have advised Bank One, Wisconsin ("Bank One") that Bucyrus International, 
Inc., a Delaware corporation (the "Borrower") intends: (i) to refinance certain 
outstanding indebtedness and (ii) to obtain financing for working capital and 
general corporate purposes (together, the Transaction).

In connection with the Transaction, you have requested that Bank One commit to 
provide to the Borrower a Senior Secured Revolving Credit Facility in an 
Aggregate principal amount of $75,000,000 (the "Revolving Credit Facility"), of 
which up to $25,000,000 will be available as a letter of credit facility.  We 
understand that simultaneous with this financing, American Industrial partners 
will be raising $150,000,000 of new unsecured high yield debt and investing 
$143,000,000 in equity to obtain 100% ownership of the Borrower.

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

      1.  Commitment. Bank One hereby commits to provide to the Borrower the
          entire Aggregate Revolving Loan Commitment for the Revolving Credit
          Facility upon the terms and subject to the conditions set forth or
          referred to herein (this letter being sometimes referred to as the
          "Commitment Letter"), in the fee letter (the "Fee Letter") dated the
          date hereof and delivered to the Borrower, and in the Summary of Terms
          and Conditions attached hereto as Exhibit A (the "Term Sheet"). Except
          as otherwise defined herein, terms which are defined in the Term Sheet
          (including "Aggregate Revolving Loan Commitment" and "Revolving Credit
          Facility") shall have the Same meanings when used in this letter as
          are ascribed to them in the Term Sheet.
<PAGE>
 
2.      Syndication. Bank One Capital Markets ("BOCM"), a division of Banc One
        -----------
        Corporation, shall have the exclusive right and intends, prior to or
        after the execution of definitive documentation of the Revolving Credit
        Facility, to syndicate a portion of the Aggregate Revolving Loan
        commitment to one or more financial institutions (Bank One and such
        financial institutions being referred to herein as the "Lenders") that
        will become parties to the definitive credit documentation for the
        Revolving Credit Facility. In that connection, promptly following your
        acceptance of this commitment, BOCM will commence the syndication of the
        Revolving Credit Facility to such Lenders. The Borrower agrees that no
        Lender will receive compensation outside the terms contained herein and
        in the Fee Letter referred to below in order to obtain its commitment to
        participate in the Revolving Credit Facility. It is understood and
        agreed that the amount and distribution of the fees referred to herein
        among the Lenders and to the Agent will be as described in the Fee
        Letter. It is understood and agreed that BOCM will manage all aspects of
        the syndication, including, without limitation, decisions as to the
        selection of potential Lenders to be approached and when they will be
        approached, when their commitments will be accepted, which Lenders will
        participate (which decisions will be made after consultation with the
        Borrower), any naming rights (including the naming of co-agents, subject
        to your reasonable approval) and the final allocations of the Aggregate
        Revolving Loan Commitment among the Lenders (which are likely not to be
        equal among all lenders).

        You agree actively to assist BOCM in achieving a timely syndication that
        is satisfactory to BOCM. 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
        Borrower) and advisors and affiliates of the Borrower on the one hand
        and the proposed syndicate Lenders on the other hand. To assist BOCM in
        its syndication efforts, you agree that you will, promptly, upon BOCM's
        request, (a) provide, and cause your affiliates and advisors to provide,
        to BOCM all information reasonably deemed necessary by BOCM to complete
        successfully the syndication, including but not limited to, information
        and projections (including, without limitation, any updated projections
        requested by BOCM) prepared by you or on your behalf relating to the
        Transaction and (b) assist, and to cause your affiliates and advisors to
        assist, BOCM in the preparation of a confidential information memorandum
        and other marketing material to be used in connection with the
        syndication, including making available representatives of the Borrower
        and its subsidiaries.

     business, assets, liabilities (contingent or otherwise) operations,

        several, to which any such Indemnified Party may become subject arising

        expenses of due diligence investigation, syndication expenses, appraisal
        expenses, Field examination expenses, audit expenses, travel expenses,
        and the reasonable fees, disbursements and other charges of counsel)

        connection therewith.

8.      Termination. This Commitment shall expire automatically on October 30,
        -----------

        withstanding the foregoing, the compensation, reimbursement,
        indemnification and confidentiality provisions hereof and of the Term

     10.   Waiver of Jury Trial. The borrower, Bank One, and BOCM waive all
           --------------------

           (whether based upon contract, tort or otherwise) related to or
           arising out of any of the transactions contemplated by this

Mr. Willard R. Hildebrand
President and Chief Executive Officer
Bucyrus International, Inc.
1100 Milwaukee Avenue, P.O. Box 300
South Milwaukee, WI 53172-0500

Dear Bill:

Salomon Brothers Inc ("Salomon Brothers" or "Salomon") has been asked by Bucyrus
International, Inc. ("Bucyrus" or the "Company") to review the feasibility of 
raising permanent financing for the proposed acquisition (the "Marion 
Acquisition") of certain assets and liabilities of The Marion Power Shovel 
Company ("Marion"), a wholly-owned subsidiary of Global Technologies, Inc. 
("Global"), as well as the acquisition of 100% of the capital stock of Bucyrus 
(the"AIP Acquisition") by an entity or entities formed by American Industrial 
Partners Capital Fund II, L.P. ("AIP") (The Marion Acquisition, together with 
the AIP Acquisition, the "Transactions"). Furthermore, it is our understanding 
that a proposed $150 million Senior Notes offering, along with a draw of 
approximately $28 million on a new $75 million Revolver provided by Bank One, 
Milwaukee, and the contribution of approximately $143 million in common equity 
by AIP will allow you to complete the Transactions, as well as to refinance 
certain debt, including bridge debt associated with the Marion Acquisition, and 
pay fees and expenses related to the Transactions.

In evaluating the Transactions, pursuant to your request, we have reviewed 
certain information you have provided to us with respect to the Company and 
Marion, including the Confidential Offering Memorandum dated January 1997 
relating to Marion, Bucyrus management's and AIP's projections for the Company, 
Marion and Bucyrus financial statements pro forma for the Marion Acquisition, a 
draft Offering Memorandum prepared in connection with a proposed financing of 
the Marion Acquisition, as well as other due diligence materials. In addition, 
we have met with or spoken to certain officers and employees of the Company, 
Marion and AIP. We have also reviewed publicly available information with 
regard to financings undertaken for companies we believe to be comparable to 
the Company, as well as certain other information we considered relevant in our 
analysis. We have assumed and relied, without assuming any responsibility for 
independent verification, upon the accuracy and completeness of all the 
financial and other information reviewed by us for the purpose of this letter. 
With respect to financial forecasts and projections, we have assumed that such 
financial forecasts and projections have been reasonably prepared on a basis 
reflecting the best currently available estimates and judgments of the Company.

We are pleased to inform you, based on and subject to the items discussed in 
this letter, that Salomon Brothers is highly confident that it could raise 
approximately $150 million of Senior Notes (the "Public Financing"), concurrent 
with the other financing described below, through a

144A offering with subsequent registration rights subject to the conditions set 
forth below and satisfactory resolution of the following items: (i) the 
Company's receipt of the other components of the financing, including the bank 
facility and the equity contributions from AIP either prior to or concurrent 
with the closing of the Public Financing; (ii) obtaining ratings from Moody's 
and Standard & Poor's for the issue of at least single "B"; (iii) the 
consummation of the Marion Acquisition by the Company on terms and conditions 
and pursuant to documentation satisfactory to us; (iv) the receipt of any 
necessary regulatory or contractual consents or approvals in connection with the
Transactions and the related financings (including Hart-Scott-Rodino for the 
Marion Acquisition and AIP Acquisition); (v) the satisfactory completion of due 
diligence on the Transactions by Salomon Brother; (vi) the negotiation and 
documentation of the Public Financing, including the terms and conditions of the
Public Financing, in form and substance satisfactory to us; and (vii) the 
execution of purchase and registration agreements for the Public Financing in 
form and substance satisfactory to us.

It should be noted that Salomon Brothers' expression of its confidence in its
ability to arrange the Public Financing as set forth above is further contingent
upon there being no material adverse change in: (i) the business, assets,
condition (financial or otherwise), results of operations or prospects of the
Company or Marion; (ii) the legal or regulatory environment for the Company or
Marion; (iii) the financial markets or events affecting the financial markets
that would, in the case of these clauses (i), (ii) and (iii), in Salomon
Brothers' sole judgment, make it inadvisable or impractical to proceed with the
Transactions or any portion of the financing thereof, including the Public
Financing.

This letter is not intended to be, and shall not constitute, a commitment or 
undertaking by Salomon Brothers to place or purchase any securities on a 
principal or agency basis or to provide any portion of the financing for the 
Transactions, including the Public Financing. This letter is confidential and is
intended solely for use by the Company and its representatives in connection 
with the Transactions. Neither the Company nor its representatives shall quote

          (a)  Promptly upon the purchase of any Shares by the Purchaser
pursuant to the Offer, and from time to time thereafter as Shares are acquired
by the Purchaser, Parent shall be entitled to designate such number of
directors, rounded up to the next whole number, on the Board of Directors of the
Company as is equal to the product of the total number of directors on such
Board (giving effect to the directors designated by Parent pursuant to this
sentence) multiplied by the percentage that the number of Shares beneficially
owned by the Purchaser or any affiliate of the Purchaser bears to the total
number of Shares then outstanding. In furtherance thereof, the Board of
Directors has resolved as part of its approval of this Agreement to promptly
increase the size of the Board of Directors upon the request of Parent, and upon
the request of Parent, the Company shall promptly increase the size of the Board
of Directors or use its best efforts to secure the resignations of such number
of its incumbent directors as is necessary to enable Parent's designees to be
elected to the Board of Directors in accordance with the terms of this Section
1.3, and shall take all actions available to the Company to cause Parent's
designees to be so elected. At such time, the Company shall, if requested by

to constitute at least the same percentage (rounded up to the next whole number)
as is on the Board of Directors of (i) each committee of the Board of Directors,
(ii) each board of directors (or similar body) of each Subsidiary (as defined in
Section 3.1 hereof) of the Company and (iii) each committee (or similar body) of

directors as is required under Section 14(f) and Rule 14f-1 in order to fulfill
its obligations under Section 1.3(a).  Parent or the Purchaser shall supply the
Company and be solely responsible for any information with respect to either of
them and their nominees, officers, directors and affiliates required by such
Section 14(f) and Rule 14f-1.  The provisions of this Section 1.3(b) are in
addition to and shall not limit any rights which the Purchaser, Parent or any of
their affiliates may have as a holder or beneficial owner of Shares as a matter
of law with respect to the election of directors or otherwise.

Directors, subject to the other terms of this Agreement, until the Effective
Time (as defined in Section 1.5 hereof), the Board of Directors shall have at
least one director who is a director on the date hereof and who is neither an
officer of the Company nor a designee, stockholder, affiliate or associate
(within the meaning of the federal securities laws) of Parent (one or more of
such directors, the "Independent Directors"), provided that, if no Independent
                     ---------------------    --------                        
Directors remain, the other directors shall designate one person to fill one of
the vacancies who shall not be either an officer of the Company or a designee,
shareholder, affiliate or associate of the Purchaser and such person shall be
deemed to be an Independent Director for purposes of this Agreement.
Notwithstanding anything in this Agreement to the contrary, in the event that
Parent's designees are elected to the Company's Board of Directors, after the
acceptance for payment of Shares pursuant to the Offer and prior to the
Effective Time (as hereinafter defined), the affirmative vote of a majority of
the Independent Directors shall be required to (i) amend or terminate this
Agreement on behalf of the Company, (ii) exercise or waive any of the Company's
rights, benefits or remedies hereunder, (iii) extend the time for performance
of the Purchaser's obligations hereunder or (iv) take any other action by the
Company under or in connection with this Agreement required to be taken by the
Board of Directors.

          Section 2.2  Dissenting Shares.
                       ----------------- 

          (a)  Notwithstanding any provision of this Agreement to the contrary,
any Shares held by a holder who has demanded and perfected his demand for
appraisal of his Shares in accordance with Delaware Law (including but not
limited to Section 262 thereof) and as of the Effective Time has neither
effectively withdrawn nor lost his right to such appraisal ("Dissenting
                                                             ----------
Shares"), shall not be converted into or represent a right to receive cash
pursuant to Section 2.1, but the holder thereof shall be entitled to only such
rights as are granted by Delaware Law.

          (b)  Notwithstanding the provisions of Section 2.2(a), if any holder
of Shares who demands appraisal of his Shares under Delaware Law shall
effectively withdraw or lose (through failure to perfect or otherwise) his right
to appraisal, then as of the Effective Time or the occurrence of such event,
whichever later occurs, such holder's Shares shall automatically be converted
into and represent only the right to receive the Merger Consideration as
provided in Section 2.1(a), without interest thereon, upon surrender of the
certificate or certificates representing such Shares pursuant to Section 2.3
hereof.

          (c) The Company shall give the Purchaser (i) prompt notice of any
written demands for appraisal or payment of the fair value of any Shares,
withdrawals of such demands, and any other instruments served pursuant to
Delaware Law received by the Company and (ii) the opportunity to direct all
negotiations and proceedings with

                                       13

respect to demands for appraisal under Delaware Law.  The Company shall not
voluntarily make any payment with respect to any demands for appraisal and shall
not, except with the prior written consent of the Purchaser, settle or offer to
settle any such demands.

          Section 2.3  Surrender of Shares; Stock Transfer Books.
                       ----------------------------------------- 

          (a)  Before the Effective Time, the Purchaser shall designate a bank
or trust company reasonably acceptable to the Company to act as agent for the
holders of Shares in connection with the Merger (the "Exchange Agent") to
                                                      --------------     
receive the funds necessary to make the payments contemplated by Section
2.1(a).  At the Effective Time, the Purchaser shall deposit, or cause to be
deposited, in trust with the Exchange Agent for the benefit of holders of
Shares the aggregate consideration to which such holders shall be entitled at
the Effective Time pursuant to Section 2.1(a).

          (b)  Each holder of a certificate or certificates representing any
Shares cancelled upon the Merger, which immediately prior to the Effective Time
represented outstanding Shares (the "Certificates") whose Shares were converted
                                     ------------                              
pursuant to Section 2.1(a) may thereafter surrender such Certificate or
Certificates to the Exchange Agent, as agent for such holder, to effect the
surrender of such Certificate or Certificates on such holder's behalf for a
period ending six months after the Effective Time.  The Purchaser agrees that
promptly after the Effective Time it shall cause the distribution to holders of
record of Shares as of the Effective Time of appropriate materials to facilitate
such surrender.  Upon the surrender of Certificates, the Purchaser shall cause
the Exchange Agent to pay the holder of such certificates in exchange therefor
cash in an amount equal to the Merger Consideration multiplied by the number of
Shares represented by such Certificate.  Until so surrendered, each Certificate
(other than Certificates representing Dissenting Shares and Certificates
representing Shares held by the Purchaser or in the treasury of the Company)
shall represent solely the right to receive the aggregate Merger Consideration,
relating thereto.

          (c)  If payment of the Merger Consideration in respect of cancelled
Shares is to be made to a Person

                                       14
<PAGE>
 
other than the Person in whose name a surrendered Certificate or instrument is
registered, it shall be a condition to such payment that the Certificate or
instrument so surrendered shall be properly endorsed or shall be otherwise in
proper form for transfer and that the Person requesting such payment shall have
paid any transfer and other taxes required by reason of such payment in a name
other than that of the registered holder of the Certificate or instrument
surrendered or shall have established to the satisfaction of the Purchaser or
the Exchange Agent that such tax either has been paid or is not applicable.

          (d)  At the Effective Time, the stock transfer books of the Company
shall be closed and there shall not be any further registration of transfers of
shares of any shares of capital stock thereafter on the records of the Company.
From and after the Effective Time, the holders of certificates evidencing
ownership of the Shares outstanding immediately prior to the Effective Time
shall cease to have any rights with respect to such Shares, except as otherwise
provided for herein or by applicable law.  If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be cancelled
and exchanged for cash as provided in this Article II.  No interest shall accrue
or be paid on any cash payable upon the surrender of a Certificate or
Certificates which immediately before the Effective Time represented outstanding
Shares.

          (e)  Promptly following the date which is six months after the
Effective Time, the Surviving Corporation shall be entitled to require the
Exchange Agent to deliver to it any cash (including any interest received with
respect thereto), Certificates and other documents in its possession relating to
the transactions contemplated hereby, which had been made available to the
Exchange Agent and which have not been disbursed to holders of Certificates, and
thereafter such holders shall be entitled to look to the Surviving Corporation
(subject to abandoned property, escheat or similar laws) only as general
creditors thereof with respect to the Merger Consideration payable upon due
surrender of their Certificates, without any interest thereon.  Notwithstanding
the foregoing neither the Surviving Corporation nor the Exchange Agent shall be
liable to any holder of a Certificate for Merger Consideration delivered to a

                                       15
<PAGE>
 
public official pursuant to any applicable abandoned property, escheat or
similar law.

          (f)  The Merger Consideration paid in the Merger shall be net to the
holder of Shares in cash, subject to reduction only for any applicable federal
back-up withholding or, as set forth in Section 2.3(c), stock transfer taxes
payable by such holder.

          Section 2.4 Stock Plans.  (a)  At or immediately prior to the
                      -----------                                       
Effective Time, (i) each then outstanding option to purchase Shares (the
                                                                         
"Options") and each outstanding Stock Appreciation Right (the "SARs") granted

then exercisable or vested, shall be cancelled and (ii) in consideration of such
cancellation, the holders of such Options and SARs shall receive for each Share
subject to such Option or SAR an amount (subject to any applicable withholding
tax) in cash equal to the product of (A) the excess, if any, of the Offer Price
over the per Share exercise price of such Option or the per Share base price of
such SAR, as applicable, and (B) the number of Shares subject to such Option or
SAR.

property owned, leased or operated by it or the nature of the business conducted
by it makes such qualification or licensing necessary, except where the failure
to be so duly qualified or licensed and in good standing would not individually
or in the aggregate have a Company Material Adverse Effect.  Except as disclosed
in Section 3.1 of the Company Disclosure Schedule, the Company does not own any
equity interest in any corporation or other entity.

this Agreement and to consummate the Transactions.  The execution, delivery and
performance by the Company of this Agreement, and the consummation by it of the
Transactions, have been duly and validly authorized by its Board of Directors
and no other corporate action on the part of the Company is necessary to
authorize the execution and delivery by the Company of this Agreement and the
consummation by it of the Transactions, except that consummation of the Merger
may require approval of the Company's stockholders as contemplated by Section
1.11 hereof.  This Agreement has been duly executed and delivered by the Company
and, assuming due and valid authorization, execution and delivery hereof by
Parent and the Purchaser, is a valid and binding obligation of the Company

such enforcement may be subject to applicable bankruptcy, insolvency or other
similar laws, now or hereafter in effect, affecting creditors' rights generally,

Company, any of its Subsidiaries or any ERISA Affiliate since the Effective Date
of ERISA that has not been satisfied in full, and no condition exists that

Affiliate of incurring any liability under such Title, other than liability for
premiums due the Pension Benefit Guaranty Corporation ("PBGC"), which payments
                                                        ----                  
have been or will be made when due.  To the extent this representation applies
to Sections 4064, 4069 or 4204 of Title IV of ERISA, it is made not only with
respect to the ERISA Plans but also with respect to any employee benefit plan,
program, agreement or arrangement subject to Title IV of ERISA to which the
Company, any of its Subsidiaries or any ERISA Affiliate

                                       25
<PAGE>

no condition exists that presents a material risk that such proceedings will be
instituted by the PBGC.

          (e)  With respect to each of the ERISA Plans that is subject to Title
IV of ERISA, the present value of accumulated benefit obligations under such
Plan, as determined by the Plan's actuary based upon the actuarial assumptions
used for funding purposes in the most recent actuarial report prepared by such
Plan's actuary with respect to such Plan, did not, as of its latest valuation
date, exceed the then current value of the assets of such Plan allocable to such
accumulated benefit obligations.

          (f)  None of the Company, any of its Subsidiaries, any ERISA
Affiliate, any of the ERISA Plans, any trust created thereunder, nor to the
Company's knowledge, any trustee or administrator thereof has engaged in a
transaction or has taken or failed to take any action in connection with which
the Company, any of its Subsidiaries or any ERISA Affiliate could be subject to
any material liability for either a civil penalty assessed pursuant to Section
409 or 502(i) of ERISA or a tax imposed pursuant to Section 4975(a) or (b), 4976
or 4980B of the Code.

          (g)  All contributions and premiums which the Company, any of its
Subsidiaries or any ERISA Affiliate is required to pay under the terms of each
of the ERISA Plans and Section 412 of the Code, have, to the extent due, been
paid in full or properly recorded on the financial statements or records of the
Company or its Subsidiaries, and none of the ERISA Plans or any trust
established thereunder has incurred any "accumulated funding deficiency" (as
defined in Section 302 of ERISA and Section 412 of the Code), whether or not
waived, as of the last day of the most recent fiscal year of each of the ERISA
Plans ended prior to the date of this Agreement. No lien has been imposed under
Section 412(n) of the Code or Section 302(f) of ERISA on the assets of the
Company, any of its Subsidiaries or any ERISA Affiliate, and no event or
circumstance has occurred that is reason-

                                       26
<PAGE>
 
ably likely to result in the imposition of any such lien on any such assets on
account of any ERISA Plan.

          (h)  With respect to any ERISA Plan that is a "multiemployer plan," as
such term is defined in Section 3(37) of ERISA, (i) neither the Company, any of
its Subsidiaries nor any ERISA Affiliate has, since September 26, 1980, made or
suffered a "complete withdrawal" or a "partial withdrawal," as such terms are
respectively defined in Sections 4203 and 4205 of ERISA, (ii) no event has
occurred that presents a material risk of a complete or partial withdrawal,
(iii) neither the Company, each of its Subsidiaries nor any ERISA Affiliate has
any contingent liability under Section 4204 of ERISA, (iv) no circumstances
exist that present a material risk that any such multi-employer plan will go
into reorganization, and (v) the aggregate withdrawal liability of the Company,
each of its Subsidiaries and the ERISA Affiliates, computed as if a complete
withdrawal by the Company, each of its Subsidiaries and all of its ERISA
Affiliates had occurred under each such multiemployer plan on the date hereof,
would be zero.

          (i)  Each of the Plans has been operated and administered in all
material respects in accordance with applicable laws, including but not limited
to ERISA and the Code and, to the Company's knowledge, the laws of each
jurisdiction in which any of the Foreign Plans are maintained, to the extent
such laws are applicable to the Foreign Plans.

          (j)  Each of the ERISA Plans that is intended to be "qualified" within
the meaning of Section 401(a) of the Code is so qualified.  The Company has
applied for and received a currently effective determination letter from the IRS
stating that it is so qualified, and no event has occurred which would affect
such qualified status.

          (k)  Any fund established under an ERISA Plan that is intended to
satisfy the requirements of section 501(c)(9) of the Code has so satisfied such
requirements.

          (l)  To the Company's knowledge based on the advice of its independent
accountants, except as disclosed in Section 3.9(l) of the Company Disclosure

other contract, agreement or arrangement with respect to which the Company or
any of its Subsidiaries may have any liability could fail to be deductible for
federal income tax purposes by virtue of Section 162(m) or Section 280G of the
Code.

          (m)  Except as set forth in Section 3.9(m) of the Company Disclosure
Schedule, no Plan provides benefits, including without limitation death or
medical benefits (whether or not insured), with respect to current or former
employees of the Company, its Subsidiaries or any ERISA Affiliate after
retirement or other termination of service (other than (i) coverage mandated by
applicable laws, (ii) death benefits or retirement benefits under any "employee
pension plan," as that term is defined in Section 3(2) of ERISA, (iii) deferred
compensation benefits accrued as liabilities on the books of the Company, any
of its Subsidiaries or an ERISA Affiliate, or (iv) benefits, the full direct
cost of which is borne by the current or former employee (or beneficiary
thereof)).

          (n)  Except as set forth in Section 3.9(n) of the Company Disclosure
Schedule, the consummation of the transactions contemplated by this Agreement
will not (i) entitle any current or former employee, officer, director, agent
or consultant of the Company, any of its Subsidiaries or any ERISA Affiliate to
severance pay, unemployment compensation or any other similar termination
payment, or (ii) accelerate the time of payment or vesting, or increase the
amount of or otherwise enhance any benefit due any such employee, officer,
director agent or consultant.

          (o)  There are no pending or, to the Company's knowledge, threatened
or anticipated claims by or on behalf of any Plan by any employee or beneficiary
under any such Plan or otherwise involving any such Plan (other than routine
claims for benefits).

          (p)  With respect to the Foreign Plans to the Company's knowledge,
except as set forth in Schedule 3.9(p):

          (i)  All contributions to, and payments from, the Foreign Plans which
have been required to be made in accordance with the terms of any such plan,
and,

                                       28

where applicable, the law of the jurisdiction in which such plan is maintained,
have been timely made.  All such contributions to the Foreign Plans, and all
payments under the Foreign Plans, for any period ending before the Closing Date
that have not been made as of the date hereof are properly accrued and reflected
on the financial statements of the Subsidiary maintaining such plan.

          (ii)  All material reports, returns and similar documents with respect
to any Foreign Plan required to be filed with any government agency or 
distributed to any Foreign Plan participant have been duly and timely filed or
distributed.

          (iii)  Each of the Foreign Plans has obtained from the government or
governments having jurisdiction with respect to such plan any required
determination that such plans are in compliance with the laws and regulations
of such government.

          (iv)  Each of the Foreign Plans has been administered at all times, in
all material respects, in accordance with its terms.

          (v)  The assets of each of the Foreign Plans (which is an employee
pension benefit plan as defined in Section 3(2) of ERISA and is funded through a
trust, insurance contract or similar funding medium) are at least equal to the
liabilities of such plans (as determined in accordance with the most recent
actuarial valuation available with resect to such plans).

          (vi)  Purchaser will incur no material liability with respect to any
Foreign Plan solely as a result of the consummation of the transactions 
contemplated by this Agreement.

or necessary in order to make the statements therein, in light of the
circumstances under which they are made, not misleading.

          Section 4.5  Financing.  In order to finance the Transactions, Parent
                       ---------

on an unsolicited basis submitted a bona fide written proposal to the Company
relating to any such transaction which the Board of Directors determines in good
faith, after receiving advice from Jefferies & Co. or another nationally
recognized investment banking firm, represents a superior transaction to the
Offer and the Merger and (y) in the opinion of the Board of Directors of the
Company, only after receipt of a written opinion from outside legal counsel to
the Company to such effect, the failure to provide such information or access or
to engage in such discussions or negotiations would likely cause the Board of
Directors to violate its fiduciary duties to the Company's stockholders under,
or otherwise violate or subject the Board of Directors to liability under
applicable law (a Takeover Proposal which satisfies clauses (x) and (y) being
referred to herein as a "Superior Proposal").  The Company shall promptly, and

determination of the same and prior to providing any such party with any
material non-public information.  The Company shall promptly provide to Parent
any material non-public information regarding the Company provided to any other
party which was not previously provided to Parent.  At any time after two
business days following notification to Parent of the Company's intent to do so
(which notification shall include the identity of the bidder and the material
terms and conditions of the proposal) and if the Company has otherwise complied
with the terms of this Section 5.3(b), the Board of Directors may terminate this
Agreement pursuant to clause (ii) of Section 8.1(f) and enter into an agreement
with respect to a Superior Proposal, provided that the Company shall,

amount payable at the time for reimbursement of expenses pursuant to Section
8.2(b) hereof.

of Directors of the Company nor any committee thereof shall (i) withdraw or

Parent or the Purchaser, the approval or recommendation by such Board of
Directors or any such committee of the Offer, this Agreement or the Merger, (ii)
approve or recommend or propose to approve or recommend, any Takeover Proposal

Board of Directors in favor of the Merger, unless the Board of Directors
determines in good faith, after receipt of a written opinion from outside legal
counsel to the Company to such effect, that inclusion of such recommendation in
the Proxy Statement would likely cause the Board of Directors to violate its
fiduciary duties to the Company's stockholders under, or otherwise violate or
subject the Board of Directors to liability under applicable law.

          Section 6.10  Directors' and Officers' Insurance and Indemnification.
                        ------------------------------------------------------ 
(a) In the event of any threatened or actual claim, action, suit, proceeding or
investigation, whether civil, criminal or administrative, including, without
limitation, any such claim, addition, suit, proceeding or investigation by or in
the right of the Company or any of its Subsidiaries, in which any of the present
or former officers or directors (the "Indemnified Parties") of the Company or
                                      -------------------                    
any of its Subsidiaries is, or is threatened to be, made a party by reason of
the fact that he or she is or was, prior to the Effective Time, a director or
officer of the Company or any of its subsidiaries or is or was, prior to the
Effective Time, serving as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise at the
request of the Company or any of its Subsidiaries, whether such claim arises
before or after the Effective Time, the Company shall indemnify and hold
harmless, and after the Effective Time the Surviving Corporation, jointly and
severally, shall indemnify and hold harmless, as and to the full extent
permitted by applicable law, each such Indemnified Party against any losses,
claims, damages, liabilities, costs, expenses (including reasonable attorneys'
fees and expenses), judgments, fines and amounts paid in settlement in 
connection with any such claim, action, suit proceeding or investigation.  In 
the event of any such claim, action, suit proceeding or investigation (whether
arising before or after the Effective Time), (i) the Indemnified Parties may
retain counsel satisfactory to them (which counsel

                                       58
<PAGE>
 
shall be reasonably satisfactory to the Company or the Surviving Corporation),
and the Company, or the Surviving Corporation after the Effective Time, shall
pay all reasonable fees and expenses of such counsel for the Indemnified
Parties promptly as statements therefor are received and (ii) the Company and
the Surviving Corporation will use their respective reasonable efforts to assist
in the vigorous defense of any such matter; provided, that neither the Company
nor the Surviving Corporation shall be liable for any settlement effected
without its prior written consent (which consent shall not be unreasonably
withheld); and provided further that the Surviving Corporation shall have no
obligation hereunder to any Indemnified Party when and if a court of competent
jurisdiction shall ultimately determine, and such determination shall have
become final and non-appealable, that indemnification of such Indemnified Party
in the manner contemplated hereby is prohibited by applicable law.  The
Indemnified Parties as a group may retain only one law firm to represent them
with respect to each such matter unless there is, under applicable standards of
professional conduct, a conflict of interest on any significant issue between
the positions of any two or more Indemnified Parties, or any similar impediment
to the joint representation of multiple Indemnified Parties by a single law
firm.

          (b)  Until the Effective Time the Company shall keep in effect Section
7.7 of its By-Laws, and thereafter for a period of six years the Surviving
Corporation shall keep in effect in its By-Laws a provision which provides or
indemnification of the Indemnified Parties to the extent permitted by Delaware
Law.

          (c)  Parent or the Surviving Corporation shall maintain the Company's
existing officers' and directors' liability insurance ("D&O Insurance") for a
                                                        -------------        
period of not less than six years after the Effective Time; provided, that the
                                                            --------          
Parent may substitute therefor policies of substantially equivalent coverage and
amounts containing terms no less favorable to such former directors or 
officers; provided, further, if the existing D&O Insurance expires, is 
          --------  -------                                             
terminated or cancelled during such period, Parent or the Surviving Corporation
will use all reason able efforts to obtain substantially similar D&O Insurance;
provided, further, however, that in no event shall Parent be required to pay
aggregate premiums for insurance under this Section 6.10(c) in excess of 150%
of the

                                       59
<PAGE>
 
average of the aggregate premiums paid by the Company in 1995, 1996 and 1997
(through the date hereof) on an annualized basis for such purpose (the "Average
                                                                        -------
Premium"), which true and correct amounts are set forth in Section 6.10(c) of
- -------                                                                      
the Company Disclosure Schedule; and provided, further, that if the Parent or
the Surviving Corporation is unable to obtain the amount of insurance required
by this Section 6.10(c) for such aggregate premium, Parent or the Surviving
Corporation shall obtain as much insurance as can be obtained for an annual
premium not in excess of 150% of the Average Premium.

          Section 6.11  Purchaser Compliance.  Parent shall cause the Purchaser
                        --------------------                                   
to comply with all of its obligations under or related to this Agreement.

          Section 6.12  Reasonable Best Efforts.  (a) Prior to the Closing, upon
                        -----------------------                                 
the terms and subject to the conditions of this Agreement, the Purchaser and the
Company, agree to use their respective reasonable best efforts to take, or cause
to be taken, all actions, and to do, or cause to be done, all things necessary,
proper or advisable under any applicable laws to consummate and make effective
the transactions contemplated by this Agreement as promptly as practicable
including, but not limited to (i) the preparation and filing of all forms,
registrations and notices required to be filed to consummate the transactions
contemplated by this Agreement and the taking of such actions as are necessary
to obtain any requisite approvals, consents, orders, exemptions or waivers by
any third party or Governmental Entity, (ii) the preparation of any Disclosure
Documents requested by the Purchaser and (iii) the satisfaction of the other
parties' conditions to Closing.  In addition, no party hereto shall take any
action after the date hereof that would reasonably be expected to materially
delay the obtaining of, or result in not obtaining, any permission, approval or
consent from any Governmental Entity necessary to be obtained prior to Closing.

          (b)  Prior to the Closing, each party shall promptly consult with the
other parties hereto with respect to, provide any necessary information with 
respect to and provide the other (or its counsel) copies of, all filings made by
such party with any Governmental Authority or any other information supplied by
such party to a Governmental Entity in connection with this Agree-

                                       60

ment and the transactions contemplated by this Agreement.  Each party hereto
shall promptly inform the other of any communication from any Governmental
Entity regarding any of the transactions contemplated by this Agreement.  If any
party hereto or affiliate thereof receives a request for additional information
or documentary material from any such Government Entity with respect to the
transactions contemplated by this Agreement, then such party will endeavor in
good faith to make, or cause to be made, as soon as reasonably practicable and
after consultation with the other party, an appropriate response in compliance
with such request.  To the extent that transfers of permits or Environmental
Permits are required as a result of execution of this Agreement or consummation
of the transactions contemplated hereby, the Company shall use its best efforts
to effect such transfers.

          (c)  Notwithstanding the foregoing, nothing in this Agreement shall be
deemed to require the Purchaser to defend against any litigation brought by any
Governmental Entity seeking to prevent the consummation of the transactions
contemplated hereby.

          (d)  The Company agrees to use its reasonable best efforts to assist
the Purchaser in connection with obtaining any financing in connection with the
consummation of the Transactions, including the Debt Financing.  Without
limiting the generality of the foregoing, the Company shall (i) promptly prepare
all reasonably requested financial statements required to be included in the
Disclosure Documents and (ii) take all action reasonably requested by Parent
that is necessary or appropriate to effect the satisfaction and discharge of the
indenture, dated December 14, 1994 (the "Secured Notes Indenture"), between

circumstances giving rise to such condition (including any action or inaction by
Parent or the Purchaser) and may be waived by Parent or the Purchaser in whole
or in part at any time and from time to time in the sole discretion of Parent or
the Purchaser, subject in each case to the terms of this Agreement.  The failure

shall not be deemed a waiver of any such right and each such right shall be
deemed an ongoing right which may be asserted at any time and from time to time.

<PAGE>
 
          (a)  The Stockholder hereby grants to Parent an irrevocable option

                --------------                                            

          (b)  At any time or from time to time prior to the termination of the
Option granted hereunder in accordance with the terms of this Agreement, Parent

     Exchange Act)) of 50% or more of the then outstanding voting equity of the
     Company (either on a primary or a fully diluted basis);

               (B)  acquired beneficial ownership of shares of Common Stock
     which, when aggregated with any shares of Common Stock already owned by

     aggregate beneficial ownership by such Third Party, its affiliates and
     associates of 15% or more of the then outstanding voting equity of the
     Company (either on a primary or a fully diluted basis), provided, however,

     than an additional 1% of the outstanding voting equity of the Company

     rules under the Exchange Act, executed any written consent or become a
     "participant" in any "solicitation" (as such terms are defined in
     Regulation 14A under the Exchange Act), in each case with respect to the
     Common Stock; or

               (ii)  any of the events described in Section 8.1(g) or (h) of the
     Merger Agreement that would allow Parent to terminate the Merger Agreement
     has occurred (but without the necessity of Parent having terminated the
     Merger Agreement).

          In the event that Parent wishes to exercise all or any part of the
Option, Parent shall give written notice (the "Option Notice", with the date of
                                               -------------                   
the Option Notice being hereinafter called the "Notice Date") to the Stockholder
                                                -----------                     
specifying the number of Shares it will purchase and a place and date (not
earlier than three (3) nor later than twenty (20) business days from the Notice
Date) for closing such purchase (a "Closing").  Parent's obligation to purchase
                                    -------                                    
Shares upon any exercise of the Option, and the Stockholder's obligation to sell
Shares upon any exercise of the Option, is subject (at the election of each of
Parent or the Stockholder) to the conditions that (i) no preliminary or
permanent injunction or

                                       9
<PAGE>
 
other order against the purchase, issuance or delivery of the Shares issued by
any federal, state or foreign court of competent jurisdiction shall be in effect
(and no action or proceeding shall have been commenced or threatened for
purposes of obtaining such an injunction or order) and (ii) any applicable
waiting period under the HSR Act shall have expired.  The Parent's obligation to
purchase Shares upon any exercise of the Option is further subject (at its
election) to the condition that there shall have been no material breach of the
representations, warranties, covenants or agreements of the Stockholder
contained in this Agreement or of the Company contained in the Merger Agreement.
Notwithstanding the foregoing, any failure by Parent to purchase Shares upon
exercise of the Option at any Closing as a result of the non-satisfaction of any
of the foregoing conditions shall not affect or prejudice Parent's right to
purchase such Shares upon the subsequent satisfaction of such conditions.  The
Stockholder's obligation to sell Shares upon any exercise of the Option (and the
Stockholder's obligations under Section 5 of this Agreement) is subject (at its
election) to the further conditions that there shall have been no material
breach of the representations, warranties, covenants or agreements of the
Purchaser or the Parent contained in this Agreement or contained in the Merger
Agreement, which breach has not been cured within thirty days of the receipt of
written notice thereof from the Stockholder.

          (c)  At any Closing, (i) the Stockholder will deliver to Parent the
certificate or certificates representing the number of Shares being purchased in
proper form for transfer upon exercise of the Option in the denominations
designated by Parent in the Option Notice, and, if the Option has been exercised
in part, a new Option evidencing the rights of Parent to purchase the balance of
the Shares subject thereto, and (ii) Parent shall pay the aggregate purchase
price for the Shares to be purchased by wire transfer of immediately available
funds to an account, which account shall be designated in writing to Parent
within five days after execution of this Agreement in the amount of the Exercise
Price times the number of Shares to be purchased.

          (d)  Notwithstanding any other provision of this Agreement, in the
event that the Merger Agreement is terminated and at any time prior to the
Termination

                                      10
<PAGE>
 
Date (as hereinafter defined) a person other than Parent or any of its
affiliates acquires a majority of the outstanding shares of Common Stock at a
price higher than the Exercise Price (an "Alternative Transaction"), then Parent
                                          -----------------------               
shall promptly either reduce the number of Shares subject to the Option, pay
cash to the Stockholder or do both such that the actual Total Profit (as
hereinafter defined) realized or to be realized by Parent upon the consummation
of an Alternative Transaction does not exceed 50% of the Total Profit that
Parent would otherwise realize had it not taken the foregoing actions; provided
                                                                        --------
that, in the event that Parent elects to reduce the number of Shares subject to
the Option, there shall be pending, at the time Parent makes such election, a
transaction involving the Company that, if consummated, would allow the
Stockholder to dispose of any remaining Shares that would not otherwise be
purchased by Parent upon the exercise of the Option; provided, further, that in
the event such transaction is not consummated within three months following the
time Parent makes such election, Parent shall, at the option of the
Stockholder, purchase any remaining Shares held by the Stockholder such that
Parent and the Stockholder each retain 50% of the Total Profit following such
purchase.  As used herein, the term "Total Profit" shall mean the aggregate
                                      ------------                          
amount (before taxes) of the net cash amounts and the fair market value (as
reasonably determined by a nationally recognized investment banking firm
acceptable to each of Parent and the Stockholder or, if one cannot be agreed
upon, by Salomon Brothers, Inc.) of all other forms of consideration received or
to be received by Parent pursuant to the sale of the aggregate number of Shares
subject to the Option (or any other securities into which such Shares are
converted or exchanged) in any Alternative Transaction, less the aggregate
Exercise Price of all of such Shares.

          (e)  In the event that Parent or the Purchaser pays a price higher
than $18.00 per share for Shares tendered into the Offer, the Exercise Price
shall be increased to equal such higher price.

          (f)  The Stockholder has granted the Option to the Parent in order to
induce Parent to enter into and consummate the transactions contemplated by the
Merger Agreement.  Parent covenants and agrees that it will perform its
obligations under the Merger Agreement.

The provisions of this Section 7(f) are intended both for the benefit of the
Stockholder and for the benefit of the Company and the other stockholders of the
Company, and may not be modified, waived or amended without the consent of the
Company.

          SECTION 8.  Certain Other Agreements.
                      ------------------------ 

          (a)  The Stockholder will notify the Purchaser immediately if any
proposals are received by, any information is requested from, or any
negotiations or discussions are sought to be initiated or continued with the
Stockholder or its officers, directors, employees, investment bankers,
attorneys, accountants or other agents, in each case in connection with any
Takeover Proposal or Takeover Proposal Interest (as such terms are defined in
the Merger Agreement) indicating, in connection with such notice, the name of
the person indicating such Takeover Proposal Interest and the terms and 
conditions of any proposals or offers.  The Stockholder agrees that it will
immediately cease and cause to be terminated any existing activities,
discussions or negotiations with any parties conducted heretofore with respect
to any Takeover Proposal Interest.  The Stockholder agrees that it shall keep
Parent informed, on a current basis, of the status and terms of any Takeover
Proposal Interest.  The Stockholder agrees that it will not, and will use its
best efforts to ensure that its officers, directors, employees, investment

wholly-owned subsidiary of Guarantor; and

          WHEREAS, the Company, Parent, and the Purchaser have entered into an

enter into this Guarantee. The Guarantor has all requisite legal power and
authority to carry out and perform its obligations under the terms of this
Guarantee. The Guarantee constitutes the valid and binding obligation of

enforcement may be limited by bankruptcy, insolvency, moratorium,
reorganization or other laws or equitable principles relating to or affecting
creditors' rights generally.

               c.   All partnership action on the part of Guarantor and its
general partner and limited partners necessary to authorize the execution,
delivery and performance of this Guarantee has been taken.

                           CONFIDENTIALITY AGREEMENT

   THIS CONFIDENTIALITY AGREEMENT, dated as of July 1, 1997, is made by and 
between Bucyrus International, Inc., a Delaware corporation ("Bucyrus") and 
American Industrial Partners ("Advisor").

   WHEREAS, Bucyrus has requested that Advisor provide certain information to 
Bucyrus and participate in discussions with Bucyrus regarding certain future 
business agreements relating to Bucyrus, and
  
   WHEREAS, in order to further such discussions, Advisor has requested access 
to certain information concerning Bucyrus and its business, and Bucyrus has 
consented to provide such information subject to restrictions on its use and 
further disclosure, and

   WHEREAS, Advisor recognizes that the information requested and/or provided by
Bucyrus is non-public, confidential and/or proprietary and, in consideration of 
its disclosure hereunder, is willing to abide by the restrictions required by 
Bucyrus.

   NOW, THEREFORE, in consideration of the foregoing, and the mutual covenants 
contained herein, and other good and valuable information, the receipt of which 
is hereby mutually acknowledged, the parties hereby agree as follows:

   1.  Advisor agrees to treat all information and materials about Bucyrus 
disclosed by Bucyrus during the course of these discussions as confidential, and
to hold all such information and materials ("Confidential Information") in trust
and confidence, exercising no less care in maintaining the security thereof as 
Advisor does or would with respect to its own confidential and proprietary 
information.

   2.  Advisor agrees to use Confidential Information only for the purpose of 
considering, analyzing and providing information to Bucyrus regarding the
business agreements referenced above.

   3.  Advisor will limit the disclosure, distribution and discussion of
Confidential Information to those directors, officers, employees and consultants
of Advisor who are (a) directly involved in Advisor's consideration of the
proposed transaction and (b) aware of and subject to Advisor's obligations of
confidentiality hereunder. In the event Advisor or any person to whom Advisor
has disclosed Confidential Information becomes legally compelled to disclose any
Confidential Information, such person will provide Bucyrus with prompt notice of
such requirement so that Bucyrus may seek a protective order or other
appropriate remedy and/or waive compliance with the terms of this agreement. In
the event a protective order or other remedy is
<PAGE>
 
not obtained, or compliance is waived, Advisor agrees that there will be
furnished to the authorities compelling disclosure only such portion of the
Confidential Information as Advisor's counsel shall advise in writing must be
disclosed. Prior to such disclosure, Advisor and Bucyrus will consult and use
all reasonable efforts to agree on the nature, form, timing and content of such
disclosure.

    4.  Upon the request of Bucyrus, Advisor shall return to Bucyrus all written
Confidential Information, and shall promptly destroy all copies of any analyses,
summaries or extracts prepared by Advisor or for its use containing or 
reflecting any Confidential Information.  Advisor shall provide a written 
affidavit, signed by an officer of Advisor, that all such Confidential 
Information has been returned or destroyed.

    5.  Neither Advisor nor any affiliate of Advisor shall, prior to the third
anniversary date of this agreement, without the prior written consent of
Bucyrus' Board of Directors:

        a.  effect or propose or make any statement publicly or to the Board of
            Directors of Bucyrus with respect to (i) any form of business
            combination with, or restructuring or recapitalization of Bucyrus,
            (ii) any purchase of securities or assets of Bucyrus, or (iii) any
            proposal to seek representation on the Board of Directors of Bucyrus
            or otherwise to seek to influence or control the management, Board
            of Directors or policies of Bucyrus, or

        b.  instigate, encourage, join, act in concert with or assist any third
            party in doing any of the foregoing, other than as a participant in
            a transaction when the Advisor is not the lead participant, not in
            control and is not the agent.

    6.  Advisor acknowledges that it is aware, and that it will advise all 
persons who are informed as to the matters which are the subject of this 
agreement, that applicable securities laws may prohibit any person who has 
received material, non-public information about Bucyrus from purchasing or 
selling securities of Bucyrus or from communicating such information to any 
other person under circumstances in which it is reasonably forseeable that such
person is likely to purchase or sell such securities.

    7.  Advisor acknowledges that the disclosure of Confidential Information in
violation of this agreement could cause irreparable injury to Bucyrus, and that
the remedy at law for such breach would be inadequate. Therefore, if Advisor
engages in any act in violation hereof, Bucyrus shall be entitled, in addition
to such other remedies and damages as may be available to it by law or
hereunder, to injunctive or other equitable relief.

    8.  The parties mutually agree not to disclose the discussions contemplated 
by this agreement to any third parties except as and in a form mutually agreed 
between the parties, or as explicitly required by law.

9.  The term "Confidential Information" does not include:
 
    a. information which was known to Advisor prior to receipt from Bucyrus:

    b. information which is now generally available in the public domain, or
       which in the future enters the public domain through no fault of Advisor,
       but only from such date as such information becomes so available;

    c. information which is disclosed to Advisor at any time by a third party
       without violation by such party of an independent obligation of
       confidentiality (but for a period of two years following the date of this
       agreement, Advisor shall, before using or further disclosing information
       so obtained, take resonable steps to determine the circumstances under
       which such information was obtained by such third party);

    d. technical information which was or is independently developed by an
       employee or Advisor not having access to Confidential Information
       supplied by Bucyrus; or

    e. information released from its confidential status by the prior written 
       consent of Bucyrus.

  10.  Bucyrus makes no representation or warranty as to the accuracy or 
completeness of Confidential Information.

  11.  This agreement shall be governed by and interpreted in accordance with 
the internal laws of the State of Wisconsin.

  IN WITNESS WHEREOF, the parties hereto have entered into this Confidentiality
Agreement as of the date first written above.
