PROSPECTUS
 
BUCYRUS INTERNATIONAL, INC.                                       [BUCYRUS LOGO]
 
 OFFER TO EXCHANGE 9 3/4% SENIOR NOTES DUE 2007 FOR ANY AND ALL EXISTING NOTES
(AS DEFINED) AS DESCRIBED HEREIN, WITHDRAWAL RIGHTS WITH RESPECT TO THE EXCHANGE
      OFFER ARE EXPECTED TO EXPIRE AT THE EXPIRATION OF THE EXCHANGE OFFER
 
THE EXCHANGE OFFER WILL EXPIRE AT 5:00 P.M., NEW YORK CITY TIME, ON DECEMBER  ,
                             1997, UNLESS EXTENDED.
 
Bucyrus International, Inc., a Delaware corporation ("Bucyrus" and, together
with its subsidiaries, the "Company"), hereby offers (the "Exchange Offer"),
upon the terms and subject to the conditions set forth in this prospectus (the
"Prospectus") and the accompanying letter of transmittal (the "Letter of
Transmittal"), to exchange up to $150,000,000 aggregate principal amount of its
9 3/4% Senior Notes Due 2007 (the "Exchange Notes"), which have been registered
under the Securities Act of 1933, as amended (the "Securities Act"), pursuant to
a Registration Statement (as defined) of which this Prospectus is a part, for a
like principal amount of its outstanding 9 3/4% Senior Notes Due 2007 (the
"Existing Notes" and, together with the Exchange Notes, the "Notes"). The
Existing Notes were originally issued in a transaction that was exempt from
registration under the Securities Act (the "Private Offering") and since such
issuance have been resold to (i) qualified institutional buyers in reliance on,
and subject to the restrictions imposed pursuant to, Rule 144A under the
Securities Act ("Rule 144A") and (ii) non-U.S. persons outside the United States
of America in accordance with Regulation S under the Securities Act ("Regulation
S"). The terms of the Exchange Notes are identical in all material respects to
the terms of the Existing Notes that are to be exchanged therefor except that
the Exchange Notes have been registered under the Securities Act and will not
bear legends restricting the transferability thereof, certain registration
rights relating to the Existing Notes will terminate upon completion of the
Exchange Offer, and, if the Exchange Offer is not consummated by March 23, 1998,
Liquidated Damages (as defined) will accrue until but not including the date the
Exchange Offer is consummated. See "Description of the Notes" and "Exchange
Offer; Registration Rights." For federal income tax purposes, an exchange made
pursuant to the Exchange Offer should not constitute a taxable exchange. See
"Exchange Offer; Registration Rights -- Certain Federal Tax Consequences."
 
Based on interpretations by the staff of the Securities and Exchange Commission
(the "Commission" or "SEC"), as set forth in no-action letters issued to third
parties, Bucyrus believes the Exchange Notes issued pursuant to the Exchange
Offer may be offered for resale, resold and otherwise transferred by holders
thereof (other than any such holder that is an "affiliate" of Bucyrus within the
meaning of Rule 405 under the Securities Act) without compliance with the
registration and prospectus delivery provisions of the Securities Act, provided
that such Exchange Notes are acquired in the ordinary course of such holders'
business, such holders are not engaged in and do not intend to engage in, a
distribution of such Exchange Notes and such holders have no arrangement or
understanding with any person to participate in the distribution of such
Exchange Notes. However, the Commission has not considered the Exchange Offer in
the context of a no-action letter and therefore there can be no assurance that
the staff of the Commission would make a similar determination with respect to
the Exchange Offer as in such other circumstances.
 
SEE "RISK FACTORS" ON PAGE 13 FOR A DESCRIPTION OF CERTAIN FACTORS THAT SHOULD
BE CONSIDERED IN CONNECTION WITH THE EXCHANGE OFFER AND AN INVESTMENT IN THE
EXCHANGE NOTES OFFERED HEREBY.
 
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR BY ANY STATE SECURITIES COMMISSION NOR HAS THE COMMISSION
OR ANY STATE SECURITIES COMMISSION PASSED UPON THE ACCURACY OR ADEQUACY OF THIS
     PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.
 
                The date of this Prospectus is November  , 1997.
<PAGE>   5
 
Each holder of Existing Notes that desires to participate in the Exchange Offer,
other than a broker-dealer, must acknowledge that it is not engaged in, and does
not intend to engage in, a distribution of Exchange Notes and has no arrangement
or understanding to participate in a distribution of Exchange Notes. Each
broker-dealer that receives Exchange Notes for its own account pursuant to the
Exchange Offer must acknowledge that it will deliver a prospectus in connection
with any resale of such Exchange Notes. The Letter of Transmittal states that by
so acknowledging and by delivering a prospectus, a broker-dealer will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act. This Prospectus, as it may be amended or supplemented from time to time,
may be used by a broker-dealer in connection with resales of Exchange Notes
received in exchange for Existing Notes where such Existing Notes were acquired
by such broker-dealer as a result of market-making activities or other trading
activities. As described more fully herein, for a period of one year after the
Expiration Date (as defined), Bucyrus will make this Prospectus available to any
Participating Broker-Dealer (as defined) for use in connection with any such
resale. See "The Exchange Offer" and "Plan of Distribution."
 
EXCEPT AS DESCRIBED IN THE PRECEDING PARAGRAPH, THIS PROSPECTUS MAY NOT BE USED
FOR AN OFFER TO RESELL, A RESALE OR ANY OTHER RETRANSFER OF EXCHANGE NOTES.
 
The Exchange Offer is not conditioned upon any minimum number of Existing Notes
being tendered. The Exchange Offer will expire at 5:00 p.m., New York City time,
on December   , 1997, unless extended (the "Expiration Date"). Subject to the
terms and conditions of the Exchange Offer, including the reservation of certain
rights by Bucyrus and the right of holders of Existing Notes to withdraw tenders
prior to the acceptance thereof, Existing Notes validly tendered prior to the
Expiration Date will be accepted on or promptly after the Expiration Date.
Exchange Notes to be issued in exchange for properly tendered Existing Notes
will be mailed by the Exchange Agent (as defined herein) promptly after the
acceptance thereof. In the event Bucyrus terminates the Exchange Offer and does
not accept for exchange any Existing Notes, Bucyrus will promptly return the
Existing Notes to the holders thereof. See "The Exchange Offer."
 
The Notes will mature on September 15, 2007. Interest on the Notes will be
payable semiannually on March 15 and September 15 of each year, commencing March
15, 1998. The Existing Notes are, and the Exchange Notes will be, redeemable at
the option of Bucyrus, in whole or in part, at any time on or after September
15, 2002, at the redemption prices set forth herein, plus accrued and unpaid
interest, if any, to the date of redemption. In addition, at any time or from
time to time on or prior to September 15, 2000, Bucyrus may redeem Notes with
the net cash proceeds of one or more Public Equity Offerings (as defined) at a
redemption price equal to 109.75% of the principal amount thereof, plus accrued
and unpaid interest, if any, to the date of redemption; provided, however, that
at least 66% of the principal amount of the Notes originally issued remains
outstanding after each such redemption. Upon a Change of Control (as defined),
each holder of Notes will have the right to require Bucyrus to purchase all or a
portion of such holder's Notes at a purchase price equal to 101% of the
principal amount thereof, plus accrued and unpaid interest, if any, to the date
of purchase. See "Description of the Notes -- Optional Redemption" and "-- 
Change of Control."
 
The Existing Notes are, and the Exchange Notes will be, general unsecured
obligations of Bucyrus and rank senior in right of payment to all future
Indebtedness (as defined) of Bucyrus that is expressly subordinated in right of
payment to the Notes and pari passu in right of payment with all existing and
future unsecured obligations of Bucyrus that are not so subordinated. The
Existing Notes are, and the Exchange Notes will be, fully and unconditionally
guaranteed (collectively, the "Guarantees") by each domestic Restricted
Subsidiary (as defined) (collectively, the "Guarantors"). Each Guarantee is a
general unsecured obligation of the Guarantor thereof and ranks senior in right
of payment to all future Indebtedness of such Guarantor that is expressly
subordinated in right of payment to such Guarantee and pari passu in right of
payment with all existing and future unsecured obligations of such Guarantor
that are not so subordinated. The Existing Notes and the Guarantees are, and the
Exchange Notes will be, effectively subordinated to secured obligations of
Bucyrus and the Guarantors, respectively, to the extent of the assets securing
such obligations. The Existing Notes are, and the Exchange Notes will be,
<PAGE>   6
 
effectively subordinated to all existing and future liabilities, including
Indebtedness, of Bucyrus' foreign subsidiaries.
 
As of June 30, 1997, on a pro forma basis after giving effect to the
consummation of the Private Offering, the Bridge Loan (as defined), the
Revolving Credit Facility (as defined), the repayment of the Secured Notes (as
defined) and the payment of fees and expenses in connection with the foregoing
(collectively referred to herein as the "Transactions"), the Company would have
had approximately $36.0 million aggregate principal amount of secured
indebtedness, $6.1 million of outstanding letters of credit, and $47.0 million
of undrawn borrowings under the Company's $75.0 million credit facility entered
into with Bank One, Wisconsin, as of September 24, 1997 (the "Revolving Credit
Facility").
 
There has not previously been any public market for the Existing Notes or the
Exchange Notes. Bucyrus does not intend to list the Exchange Notes on any
securities exchange or to seek approval for quotation through any automated
quotation system. There can be no assurance that an active market for the
Exchange Notes will develop. See "Risk Factors -- Absence of a Public Market for
the Notes." Moreover, to the extent that Existing Notes are tendered and
accepted in the Exchange Offer, the trading market, if any, for untendered and
tendered but unaccepted Existing Notes could be adversely affected.
 
Bucyrus will not receive any proceeds from the Exchange Offer, but will bear
certain offering expenses pursuant to the Registration Agreement, dated
September 24, 1997 (the "Registration Agreement"), among Bucyrus and the Initial
Purchasers (as defined) of the Existing Notes. The Exchange Offer is intended to
satisfy certain of Bucyrus' obligations under the Registration Agreement,
including the obligation to register the exchanged Existing Notes under the
Securities Act. Upon the completion of the Exchange Offer, certain special
rights under the Registration Agreement will terminate with respect to Existing
Notes, and holders of Exchange Notes will not be entitled to such rights. See

The principal executive offices of the Company are located at 1100 Milwaukee
Avenue, P.O. Box 500, South Milwaukee, WI 53172-0500, and its telephone number
is (414) 768-4000.
 
     The industry size and growth, market share, and competitive position data
contained in this Prospectus are based on internal, industry, and other sources
that are believed to be reliable. Such data are inherently imprecise, but the
Company believes that such data are generally indicative of industry size and
growth and the Company's relative market share and competitive position.
 
                               BUSINESS OVERVIEW
 
     The Company is one of the world's leading manufacturers of large-scale
excavation equipment used in surface mining and other earth moving operations,
including rotary blast hole drills, electric mining shovels, and draglines.
Bucyrus machines are used throughout the world by customers who mine coal, iron
ore, copper, gold, phosphate, bauxite, oil sands, and other minerals, as well as
for land reclamation activities. In addition to original equipment manufacturing
("OEM"), an important part of the Company's business consists of aftermarket
sales, such as supplying parts, providing maintenance and repair services, and
providing technical advice, as well as refurbishing and relocating older,
installed machines. After giving pro forma effect to the Marion Acquisition, the
Company's net sales for fiscal 1996 would have been $373.4 million, comprised of
$143.8 million (39%) of new equipment sales and $229.6 million (61%) of
aftermarket sales, fiscal 1996 EBITDA (as defined herein) would have been $34.0
million, and consolidated backlog would have been $243.5 million at June 30,
1997.
 
     The Company manufactures the world's top selling rotary blast hole drills,
having produced a majority of the estimated 69 drills sold in the industry
during 1995 and 1996. The Company's electric mining shovels hold a significant
market position, particularly in developing areas of the world such as China and
Chile, where the Company had an estimated 83% and 65% market share,
respectively, over the last seven years. The Company also manufactures
draglines, which are the industry's largest and most expensive type of
equipment. While sales are sporadic, each dragline represents a significant
sales opportunity, and in September 1997, the Company signed an agreement with
an Australian mining company to build the world's fourth largest dragline, which
is scheduled for completion by December 31, 1999. This is expected to generate
net sales of approximately $57.5 million over the next two and a half years.
 
     The Company's aftermarket parts and service business caters primarily to
its large installed equipment base. Aftermarket support is critical in enhancing
machine longevity and productivity in the field, and its importance is a
function of the size, expense, complexity, and long service life of this type of
equipment. Over the life of a machine, net sales generated from aftermarket
parts and services can exceed the original purchase price. As a result of the
Marion Acquisition, management estimates that the Company has an installed
equipment base of nearly 1,200 machines, consisting of approximately 380
operating draglines (approximately 90% of the world's installed base),
approximately 310 operating rotary blast hole drills (approximately 65% of the
world's installed base), and approximately 485 operating electric mining shovels
(approximately 30% of the world's installed base). Management estimates that the
replacement value of the Company's installed equipment base is in excess of $9
billion based upon current purchase prices for the same or similar machines.

     During the past three years, approximately 70% of the Company's new machine
and aftermarket net sales have been in international markets. Among the more
significant foreign markets for the Company's products and services are
Australia and South Africa, as well as developing areas such as Chile and China.
The Company has an established network of foreign subsidiaries and offices that
directly market the Company's products and provide ongoing aftermarket services
overseas. The Company believes that this approach offers better customer service
and support by providing international customers with direct access to the
Company's technological and engineering expertise.
 
                             THE MARION ACQUISITION
 
     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 of
certain subsidiaries and divisions of Global that represent Global's surface
mining equipment business in Australia, Canada, and South Africa (collectively
referred to herein as "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 taken
place on June 30, 1997.
 
     The Company financed the Marion Acquisition and related fees and expenses
utilizing a $45.0 million unsecured bridge loan (the "Bridge Loan") provided by
a former affiliate of the Company which has been repaid in full with a portion
of the proceeds of the Private Offering.
 
     Marion manufactured large-scale surface mining excavation equipment,
primarily draglines and electric mining shovels, and had a significant
aftermarket parts and services business. For the fiscal year ended October 31,
1996, Marion had total net sales of $109.6 million, consisting of $36.4 million
(33%) in new equipment sales and $73.2 million (67%) in aftermarket parts and
service sales. See "Business -- The Marion Acquisition."
 
     The Marion Acquisition provides a number of benefits to the Company,
including a substantial increase in the Company's worldwide installed equipment
base, expansion of the Company's presence in several important markets, and the
opportunity to achieve significant cost savings.
 
          INCREASED INSTALLED EQUIPMENT BASE. The Marion Acquisition increased
     the Company's installed equipment base from approximately 900 machines to
     nearly 1,200 machines worldwide, providing the Company with significantly
     greater opportunities to market its aftermarket parts and services.
 
          EXPANDED PRESENCE IN POTENTIALLY HIGH GROWTH MARKETS. The Marion
     Acquisition provides the Company with an increased strategic presence in
     markets that are anticipated to experience substantial growth over the next
     several years, such as India and Russia, through Marion's established
     relationships with local mining interests and governmental authorities.
 
          SIGNIFICANT COST SAVINGS. The Marion Acquisition results in pro forma
     cost savings of $12.5 million for fiscal 1996 as described below, and $5.9
     million for the six months ended June 30, 1997, through the consolidation
     of manufacturing operations and the rationalization of engineering and
     administrative functions. In addition, the Company has identified an
     estimated $3.0 million in potential annual cost savings that are not
     reflected in the pro forma financial results. The cost savings reflected in
     the pro forma results and summarized below, and other anticipated cost
     savings, are based on assumptions and expectations that the Company
     believes to be reasonable, but are dependent on a variety of important
     factors. See "Risk Factors -- Realization of Benefits of the Marion
     Acquisition; Integration of Marion" and "Unaudited Pro Forma Combined
     Condensed Financial Statements."
 
          The Company is consolidating all of Marion's manufacturing operations
     into the Company's existing facilities as Marion's manufacturing facility
     was not acquired as part of the Marion
                                        2
<PAGE>   9
 
     Acquisition. This consolidation results in pro forma manufacturing cost
     savings of $5.0 million for fiscal 1996, including reductions in direct
     facility costs, fixed manufacturing administrative costs, and nonpayroll
     manufacturing costs. The Marion Acquisition also results in pro forma
     general and administrative cost savings for fiscal 1996 of $5.3 million
     through the consolidation of duplicative engineering, accounting, and other
     administrative staff, because only selected Marion employees were hired by
     the Company. In addition, the elimination of allocated corporate overhead
     charges results in pro forma cost savings of $2.2 million for fiscal 1996.
 
          The Company expects to generate the $3.0 million in additional cost
     savings not reflected in the pro forma financial results by reducing direct
     labor costs, consolidating engineering functions, eliminating marketing
     personnel, and closing certain duplicative parts and service locations
     resulting from the Marion Acquisition.
 
                       ACQUISITION OF THE COMPANY BY AIP
 
     On August 21, 1997, Bucyrus entered into an Agreement and Plan of Merger
(the "AIP Agreement") with American Industrial Partners Acquisition Company, LLC
("AIPAC"), which is wholly owned by American Industrial Partners Capital Fund
II, L.P. ("AIP"), and Bucyrus Acquisition Corp. ("BAC"), a wholly owned
subsidiary of AIPAC. Pursuant to the AIP Agreement, on August 26, 1997, BAC
commenced an offer to purchase for cash 100% of the common stock of Bucyrus (the
"Common Stock") at a price of $18.00 per share (the "AIP Tender Offer").
Consummation of the AIP Tender Offer occurred on September 24, 1997, and BAC was
merged with and into Bucyrus on September 26, 1997 (the "AIP Merger"). Bucyrus
is the surviving entity in the AIP Merger and is currently wholly-owned by
AIPAC.
 
     AIP is a private investment fund headquartered in San Francisco and New
York with committed capital of approximately $574 million. AIP seeks to invest
in companies with either a protected competitive position or proprietary
capability, ideally combined with a leading market share. The firm does not seek
to play a role in daily management; rather, AIP seeks to provide its portfolio
companies with access to the management expertise of its operating partners, all
of whom are former Chief Executive Officers of Fortune 500 corporations, through
active board-level participation as well as on-call advice when desired. See
"Acquisition of the Company by AIP."
 
     Following consummation of the AIP Merger, Robert L. Purdum, an operating
partner of AIP and former Chairman, President and Chief Executive Officer of
Armco Inc., is expected to become the Company's Non-Executive Chairman of the
Board. Although no specific arrangements are in place AIP intends to offer the
Company's executive officers the opportunity to own up to 10% of the Company's
equity through a combination of direct investments and option programs.
 
                               BUSINESS STRATEGY
 
     Following an in-depth, strategic review of management and operations in
1995, the Board of Directors refocused the Company's business strategy and hired
a new management team, including Willard R. Hildebrand, President and Chief
Executive Officer, and Daniel J. Smoke, Vice President and Chief Financial
Officer. In addition, the Board increased the responsibilities of four other
senior officers who had been with the Company for an average of 23 years. AIP
intends to continue the Company's existing business strategy, which includes the
following key elements:
 
          GROW THE AFTERMARKET BUSINESS. The Company has increased its focus on
     the important aftermarket business because of its attractive profit margins
     and its greater stability and predictability compared to the market for new
     equipment. In addition, providing aftermarket support, which is critical to
     maintain machine longevity and productivity in the field, enhances the
     Company's ability to secure new machine orders in the future. The Company's
     focus on its aftermarket business is reflected in a number of recently
     implemented strategic initiatives that include: (i) working with suppliers
     to increase stock levels of replacement parts to shorten
                                        3
<PAGE>   10
 
     response times to customer inquiries; (ii) installation of a new
     computerized parts quoting system to improve responsiveness to customer
     inquiries; (iii) forming a dedicated engineering team to focus on reducing
     manufacturing costs for replacement parts; (iv) enhancing relationships
     with key suppliers in order to reduce raw material and purchased part
     costs; (v) expanding the Company's facilities in important foreign markets,
     such as Chile and South Africa; (vi) investing additional capital in the
     Company's domestic repair and service subsidiaries, Boonville Mining
     Services, Inc. and Minserco, Inc.; and (vii) purchasing Von's Welding,
     Inc., an aftermarket supplier of mining machinery parts and services,
     located in Gillette, Wyoming, in North America's most important coal mining
     region.
 
          INCREASE OEM QUALITY AND PROFITABILITY. The Company is committed to
     increasing the profitability of OEM sales by improving the design and
     engineering of its existing line of machines, as well as developing new
     products. During 1996, the Company's engineering and service functions were
     significantly restructured in response to feedback from a customer focus
     group formed to provide direction to the Company's engineering development
     activities. A continuation of this close relationship with customers is
     fundamental to the Company's objective to become more market driven.
     Specific goals included reducing lead times, improving product quality and
     reliability, and improving profit margins on OEM sales. To further these
     goals, the Company has increased its investment in work-in-process
     inventory to reduce delivery times for new equipment orders. The Company's
     commitment to quality has been formally recognized by its receipt of ISO
     9001 Certification from Det Norske Veritas, one of the world's leading
     standards organizations.
 
          MODERNIZE PLANT AND EQUIPMENT. During 1996, the Company began a number
     of initiatives to modernize its manufacturing facilities in order to reduce
     lead times and inventory levels, provide quicker turn around, and reduce
     overall costs of manufacturing both new machines and replacement parts. The
     most significant initiative is a three-year, $20 million modernization
     program at the Company's South Milwaukee facility. The program includes
     replacing approximately 47 older, less efficient machines with 14
     technologically advanced machines, and upgrading 10 existing machine tools.
     As of June 30, 1997, approximately $5.5 million had been committed to this
     project and seven of the 14 machines had been installed, with the remainder
     scheduled for installation by early 1999. Following the completion of the
     modernization program, the Company expects to realize significant annual
     cost savings not reflected in the pro forma financial results through the
     reduction of labor, overhead, and raw materials costs.
 
          FOCUS ON STRATEGIC MARKETS. Although 76% of the Company's net sales of
     new machines have come from foreign markets during the past five years,
     management believes that North America (primarily the western United
     States, western Canada, and Mexico) continues to be one of the world's most
     important markets for surface mining equipment. Therefore, the Company's
     focus includes the strategic placement of its new, quality-engineered
     electric mining shovels in high-profile North American installations. The
     Company sold the first of these shovels in Canada in 1995, and in the
     United States and Mexico in 1996. The Company believes that these
     installations will create opportunities for increased new machine sales in
     North America. Management has been encouraged by repeat orders in 1997 for
     two additional shovels from one of these customers and the receipt of a
     shovel order from a new North American customer that has historically
     purchased all its equipment from the Company's primary competitor.
 
          EXPAND MARC PROGRAM. The Company is aggressively promoting its
     Maintenance and Repair Contracts ("MARCs"), under which mine operators
     outsource to the Company all regular maintenance services, repair functions
     and, in some cases, operation of the equipment serviced. MARCs offer the
     Company a generally predictable, high-margin revenue stream. The Company
     currently operates eight MARCs and is seeking to expand the MARC program,
     primarily in new mines.
                                        4

     While a number of these initiatives have not been fully implemented and the
anticipated benefits have not yet been fully realized, from 1995 to 1996 the
Company's net sales increased 14%, from $231.9 million to $263.8 million, and
EBITDA (as defined herein) improved from $12.7 million (5.5% of net sales) to
$19.2 million (7.3% of net sales). For the first six months of 1997, as compared
to the first six months of 1996, net sales increased 10%, from $130.8 million to
$143.8 million, and EBITDA (as defined herein) improved from $9.3 million (7.1%
of net sales) to $12.9 million (9.0% of net sales). The Company's consolidated
backlog at June 30, 1997 increased 36% to $215.8 million from $158.7 million at
December 31, 1996. The Marion Acquisition provides the Company with increased
opportunities to implement these initiatives, particularly with respect to
Marion's aftermarket business.

                                 Rule 405 under the Securities Act) without
                                 compliance with the registration and prospectus
                                 delivery provisions of the Securities Act,
                                 provided that such Exchange Notes are acquired
                                 in the ordinary course of such holder's
                                 business and that such holder is not engaged
                                 in, and does not intend to engage in, a
                                 distribution of such Exchange Notes and has no
                                 arrangement or understanding with any person to

                                 Each broker-dealer that receives Exchange Notes
                                 for its own account in exchange for Existing
                                 Notes pursuant to the Exchange Offer must
                                 acknowledge that such Existing Notes were
                                 acquired by such broker-dealer as a result of
                                 market-making activities or other trading
                                 activities and that it will deliver a
                                 prospectus in connection with any resale of
                                 such Exchange Notes. The Letter of Transmittal
                                 states that by so acknowledging and by
                                 delivering a prospectus, a broker-dealer will
                                 not be deemed to admit that it is an
                                 "underwriter" within the meaning of the
                                 Securities Act. This Prospectus, as it may be
                                 amended or supplemented from time to time, may
                                 be used by a broker-dealer for a period of one
                                 year after the Expiration Date in connection
                                 with resales of Exchange Notes received in
                                 exchange for Existing Notes where such Existing
                                 Notes were acquired by such broker-dealer as a
                                 result of market-making activities or other

Certain Federal Income Tax
  Consequences................   For federal income tax purposes, the exchange
                                 of an Existing Note for a Exchange Note should
                                 not constitute a taxable exchange by its
                                 holder. Accordingly, the holders should not
                                 recognize any taxable gain or loss upon such
                                 exchange. See "Exchange Offer; Registration
                                 Rights -- Certain Federal Tax Consequences."

                                 on Form S-4 (together with any amendments
                                 thereto, the "Registration Statement") with
                                 respect to the Exchange Offer made hereby, and
                                 has agreed to use its best efforts to cause the
                                        9

                                 Registration Statement to become effective on
                                 or prior to February 21, 1998. In the event
                                 that any changes in law or the applicable
                                 interpretations of the staff of the Commission
                                 do not permit Bucyrus to effect the Exchange
                                 Offer made hereby, if the Registration
                                 Statement is not declared effective on or prior
                                 to February 21, 1998, if the Exchange Offer is
                                 not consummated on or prior to March 23, 1998
                                 for any reason attributable to actions or
                                 inactions of Bucyrus, or under certain other
                                 circumstances, Bucyrus will, as promptly as
                                 practicable, file with the Commission a shelf
                                 registration statement with respect to the
                                 resale of the Existing Notes (the "Shelf
                                 Registration Statement"), use its best efforts
                                 to cause such Shelf Registration Statement to
                                 become effective generally within 30 days after
                                 the date on which Bucyrus is required to file
                                 the Shelf Registration Statement, and to keep
                                 the Shelf Registration Statement effective
                                 until three years after the effective date
                                 thereof (or until one year after such effective
                                 date if the Shelf Registration Statement is
                                 filed at the request of an Initial Purchaser).
                                 Upon consummation of the Exchange Offer,
                                 Bucyrus generally will have no further
                                 obligation to register the Existing Notes. See
                                 "Exchange Offer; Registration Rights."
 
Termination of Certain
Rights........................   Holders of Exchange Notes will not be entitled
                                 to certain rights under the Registration
                                 Agreement, including the right to require
                                 Bucyrus to file a registration statement with
                                 respect to the Exchange Notes, and to file a
                                 Shelf Registration Statement, except in certain
                                 limited circumstances. See "The Exchange Offer
                                 -- Termination of Certain Rights."
 
Absence of a Public Market for
the Exchange Notes............   The Exchange Notes will be new securities for
                                 which there currently is no market. Although
                                 the Initial Purchasers have informed the
                                 Company that they currently intend to make a
                                 market in the Exchange Notes, they are not
                                 obligated to do so, and any such market making
                                 may be discontinued at any time without notice.
                                 Accordingly, there can be no assurance as to
                                 the development or liquidity of any market for
                                 the Exchange Notes. The Company does not intend
                                 to apply for listing of the Exchange Notes on
                                 any securities exchange or for quotation
                                 through The Nasdaq National Market.
 
Use of Proceeds...............   Bucyrus will not receive any proceeds from the
                                 Exchange Offer. The net proceeds to Bucyrus
                                 from the sale of the Existing Notes were used
                                 to purchase or redeem 100% of the Company's
                                 10.5% Secured Notes due December 14, 1999 (the
                                 "Secured Notes") and to refinance indebtedness
                                 incurred in connection with the Marion
                                 Acquisition and the AIP Merger and to pay fees
                                 and expenses related thereto.
 
     For further information regarding the Exchange Notes, see "Description of
the Notes."

                  SUMMARY FINANCIAL INFORMATION AND OTHER DATA
 
     The following table presents selected historical financial data derived
from the consolidated financial statements of the Company and summary pro forma
combined data of the Company and Marion as of the dates and for each of the
periods indicated. The pro forma data were prepared to illustrate the estimated
effect of the Transactions as if the Transactions had occurred, in the case of
statement of operations data and other data, as of January 1, 1996, and in the
case of balance sheet data, as of June 30, 1997. In addition, the pro forma data
for the year ended December 31, 1996, have been prepared using Marion's results
for the fiscal year ended October 31, 1996. The results of Marion's operations
for the twelve month period ending October 31, 1996, are not necessarily
indicative of the results of Marion's operations for the twelve month period
ending December 31, 1996. The pro forma data do not purport to be indicative of
the results of operations or financial position of the Company and Marion that
actually would have been obtained if the Transactions had been completed as of
such dates or to project the results of operations or financial position of the
Company for any future date or period. The information should be read in
conjunction with "Unaudited Pro Forma Combined Condensed Financial Statements,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," and the financial statements of the Company and of Marion and
related notes thereto, included elsewhere in this Prospectus.

    reflected in the pro forma financial statements, the Company has identified
    an estimated $3,000 in potential cost savings which depend upon the
    Company's ability to successfully integrate the Marion operations into those
    of the Company. See "Risk Factors -- Realization of Benefits of the Marion
    Acquisition; Integration of Marion." The following table illustrates the
    calculation of Supplemental EBITDA and the ratio of Supplemental EBITDA to

Ratio of Supplemental EBITDA to interest expense............        2.0x         1.7x
</TABLE>
 
    The decrease in the ratio of Supplemental EBITDA to interest expense
    reflects the deteriorated operating results of Marion for the six months
    ended June 30, 1997. The Company believes that the factors that contributed
    to such deterioration include (i) diversion of Global management's
    attention to prepare Marion for its sale, (ii) decreased productivity among
    Marion employees, many of whom were not hired by the Company, and (iii)
    decreased customer orders due to the uncertainty created by pendency of the
    sale during such period. Marion's net current assets and combined equity
    decreased after June 30, 1997, and net sales decreased and the net loss
    increased subsequent to June 30, 1997 as compared to the corresponding
    period in the preceding year.
(3) Includes restructuring and reorganization charges of $9,338 and $3,496 for
    the period January 1, 1994, through December 13, 1994, and the year ended
    December 31, 1995, respectively.
(4) Following the Private Offering, the Company wrote off an estimated $3,463 of
    borrowing costs incurred in connection with the Bridge Loan. Such write-off
    was reflected in the results of operations for the three months ended
    September 30, 1997 as a charge to earnings.
(5) For purposes of this Prospectus (other than "Description of the Notes"),
    "EBITDA" is defined as earnings (loss) before (i) income taxes; (ii)
    interest expense; (iii) extraordinary gain; (iv) depreciation; (v)
    amortization; (vi) non-cash stock compensation; (vii) loss (gain) on sale of
    fixed assets; (viii) restructuring expenses; (ix) reorganization items; (x)
    inventory fair-value adjustment charged to cost of products sold; (xi) the
    AIP Management Fee (as defined), which is subordinated to the Notes and
    which the Company did not incur until the AIP Merger was consummated; and
    (xii) in 1995 only, a non-cash charge related to the scrapping and disposal
    of excess inventory related to certain older and discontinued machine
    models. See "Management's Discussion and Analysis of Financial Condition and
    Results of Operations -- EBITDA." Since cash flow from operations is very
    important to the Company's future, the EBITDA calculation provides a summary
    review of cash flow performance. EBITDA (as defined herein) should not be
    considered an alternative to operating income determined in accordance with
    generally accepted accounting principles ("GAAP") as an indicator of
    operating performance or to cash flows from operating activities determined
    in accordance with GAAP as a measure of liquidity.
(6) Backlog includes the dollar value of orders placed for new equipment as well
    as parts and services, including estimates of net sales expected to be
    generated from MARCs, minus dollars billed through manufacturing contracts,
    which are billed on a percentage of completion basis. MARC sales estimates
    are based on payments expected for parts, maintenance, and operational
    services over the life of each contract, some of which have terms through
    2002. Backlog at June 30, 1997 includes $60,200 in net sales that were
    expected to be generated by the sale of a dragline for which a letter of
    intent had been received. The Company currently expects that this dragline
    will generate net sales of $57,500 over the next two and a half years.

                                  RISK FACTORS
 
     HOLDERS OF EXISTING NOTES SHOULD CONSIDER CAREFULLY ALL OF THE INFORMATION
SET FORTH IN THIS PROSPECTUS AND, IN PARTICULAR, SHOULD EVALUATE THE FOLLOWING
RISKS BEFORE TENDERING THEIR EXISTING NOTES IN THE EXCHANGE OFFER, ALTHOUGH THE
RISK FACTORS SET FORTH BELOW ARE GENERALLY APPLICABLE TO THE EXISTING NOTES AS
WELL AS THE EXCHANGE NOTES.
 
     This Prospectus contains statements which constitute forward looking
statements within the meaning of Section 27A of the Securities Act. Discussions
containing such forward looking statements may be found under the captions
"Summary," "Management's Discussion and Analysis of Financial Condition and
Results of Operations," and "Business," as well as elsewhere within the
Prospectus. Forward looking statements include statements regarding the intent,
belief or current expectations of the Company, primarily with respect to the
future operating performance of the Company or related industry developments.
When used in this Prospectus, terms such as "anticipate," "believe," "estimate,"
"expect," "indicate," "may be," "objective," "plan," "predict," and "will be"
are intended to identify such statements. Investors in the Notes are cautioned
that any such forward looking statements are not guarantees of future
performance and involve risks and uncertainties, and that actual results may
differ from those described in the forward looking statements as a result of
various factors, many of which are beyond the control of the Company. Forward
looking statements are based upon management's expectations at the time they are
made. Actual results could differ materially from those projected in the forward
looking statements as a result of the risk factors set forth below and the
matters set forth in the Prospectus generally. The Company cautions the reader,
however, that this list of factors may not be exhaustive.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     Holders of Existing Notes who do not exchange them for Exchange Notes
pursuant to the Exchange Offer will continue to be subject to certain
restrictions on transfer of such Existing Notes. In general, the Existing Notes
may not be reoffered or resold by their holders except pursuant to an effective
registration statement under the Securities Act or pursuant to an applicable
exemption from such registration, and the Existing Notes are legended to so
restrict their transfer. Based on interpretations by the staff of the SEC, as
set forth in no-action letters issued to third parties, the Company believes
that each holder (other than any holder who is an "affiliate" of Bucyrus within
the meaning of Rule 405 under the Securities Act) who duly exchanges Existing
Notes for Exchange Notes in the Exchange Offer will receive Exchange Notes that
are freely transferable under the Securities Act, provided that such Exchange
Notes are acquired in the ordinary course of such holder's business and that
such holder is not engaged in, and does not intend to engage in, a distribution
of such Exchange Notes and has no arrangement or understanding with any person
to participate in the distribution of such Exchange Notes. By tendering Existing
Notes and executing the Letter of Transmittal, the holder thereof shall
represent and agree that (i) it is neither an affiliate of Bucyrus nor a
broker-dealer tendering Existing Notes acquired directly from Bucyrus for its
own account, (ii) it acquired the Exchange Notes in the ordinary course of its
business and (iii) it is not engaged in, and does not intend to engage in, a
distribution of the Exchange Notes and it has no arrangement or understanding to
participate in a distribution of Exchange Notes. The SEC, however, has not
considered the Exchange Offer in the context of a no-action letter, and
therefore there can be no assurance that the staff of the SEC would make a
similar determination with respect to the Exchange Offer as in such other
circumstances. Holders of Existing Notes who participate in such Exchange Offer
should be aware, however, that, except in the case of certain broker-dealers as
described below, if they accept Exchange Notes in the Exchange Offer for the
purpose of engaging in secondary resales, such Exchange Notes may not be
publicly reoffered or resold without complying with the registration and
prospectus delivery requirements of the Securities Act. The same registration
and prospectus delivery requirements would apply to any holder who is an
"affiliate" of Bucyrus within the meaning of Rule 405 under the Securities Act.
Each broker-dealer
 
                                       13
<PAGE>   20
 
that receives Exchange Notes for its own account in exchange for Existing Notes,
where such Existing Notes were acquired by such broker-dealer as a result of
market-making activities or other trading activities, must acknowledge that it
will deliver a prospectus in connection with any resale of such Exchange Notes.
See "The Exchange Offer," "Description of the Notes -- Registration Covenant;
Exchange Offer" and "Plan of Distribution."
 
     The Existing Notes may be sold pursuant to the restrictions set forth in
Rule 144A, Regulation D under the Securities Act or Regulation S without
registration under the Securities Act.
 
SUBSTANTIAL LEVERAGE; RESTRICTIVE LOAN COVENANTS
 
     As a result of the Private Offering, the Company has substantial
indebtedness and significant debt service obligations. As of June 30, 1997, on a
pro forma basis after giving effect to the Transactions, the Company would have
had total long-term indebtedness, including current maturities, of $176.2
million, as well as undrawn borrowings under the Revolving Credit Facility of
$47.0 million. The Indenture permits the Company to incur additional
indebtedness, including secured indebtedness, subject to certain limitations.
See "Capitalization," and "Description of the Notes -- Certain Covenants."
 
     The Company's high degree of leverage could have important consequences to
the holders of Existing Notes and the holders of Exchange Notes, including,
without limitation: (i) a substantial portion of the Company's cash from
operations is committed to the payment of debt service and is not available to
the Company for other purposes; (ii) the Company's ability to obtain additional
financing in the future for working capital expenditures or acquisitions may be
limited; (iii) a substantial decrease in net operating cash flows or an increase
in expenses could make it difficult for the Company to meet its debt service
requirements and force it to modify its operations; (iv) the Company may be more
highly leveraged than its competitors, which may place it at a competitive
disadvantage; (v) certain indebtedness under the Revolving Credit Facility is at
variable rates of interest, which causes the Company to be vulnerable to
increases in interest rates; and (vi) all of the indebtedness outstanding under
the Revolving Credit Facility is secured by substantially all the assets of the
Company and will become due prior to the time the principal on the Notes will
become due. Any inability of the Company to service its indebtedness or obtain
additional financing as needed would have a material adverse effect on the
Company. See "Revolving Credit Facility" and "Description of the Notes."
 
     The Company believes that based upon anticipated levels of operations
(assuming the timely integration of Marion's business into that of the Company)
it will be able to meet its debt service obligations, including interest
payments in respect of the Notes. If, however, the Company cannot generate
sufficient cash flow from operations to meet its obligations, the Company may be
required to refinance its debt or to dispose of assets to obtain funds for such
purpose. There is no assurance that refinancings or asset dispositions could be
effected on satisfactory terms or would be permitted by the terms of the
Revolving Credit Facility or the Indenture. See "-- Realization of Benefits of
the Marion Acquisition; Integration of Marion."
 
     The Revolving Credit Facility and the Indenture contain numerous covenants
that limit the discretion of management with respect to certain business matters
and place significant restrictions on, among other things, the ability of the
Company to incur additional indebtedness, to create liens or other encumbrances,
to make certain payments or investments, loans and guarantees and to sell or
otherwise dispose of assets and merge or consolidate with another entity. See
"Revolving Credit Facility" and "Description of the Notes -- Certain Covenants."
The Revolving Credit Facility also contains a number of financial covenants that
require the Company to maintain certain financial ratios (including a
consolidated fixed charge coverage ratio, a consolidated interest coverage
ratio, and a consolidated leverage ratio) and tests (including maintenance of
the Company's net worth at a specified level). A failure to comply with the
obligations contained in the Revolving Credit Facility or the Indenture could
result in an event of default under the Revolving Credit Facility or an Event of
 
                                       14
<PAGE>   21
 
Default (as defined herein) under the Indenture that, if not cured or waived,
would permit acceleration of the relevant debt and acceleration of debt under
other instruments that may contain cross-acceleration or cross-default
provisions. Other indebtedness of the Company and its subsidiaries could contain
amortization and other prepayment provisions, or financial or other covenants,
more restrictive than those applicable to the Notes.
 
REALIZATION OF BENEFITS OF THE MARION ACQUISITION; INTEGRATION OF MARION
 
     Management estimates that significant cost savings can be achieved as a
result of the integration of Marion into the Company; however, the estimates of
potential cost savings are forward looking statements that are inherently
uncertain, and the actual cost savings, if any, could differ materially from
those projected. All of these forward looking statements are based on estimates
and assumptions made by management of the Company, which although believed to be
reasonable, are inherently uncertain and difficult to predict; therefore, undue
reliance should not be placed upon such estimates.
 
     Full realization of the potential benefits and savings of the Marion
Acquisition depends upon a variety of factors, including (i) retention of a
substantial portion of Marion's net sales, particularly aftermarket sales; (ii)
achievement of significant reductions in operating costs through the
consolidation of operations and the restructuring of engineering, manufacturing,
selling, and administrative functions; and (iii) expansion of the Company's
presence in several markets where Marion has established relationships with
local mining interests and government authorities. Any material delays or
unexpected costs incurred in connection with the integration of Marion into the
Company could have a material adverse effect on the Company and its results of
operations, liquidity, and financial condition.
 
     The integration of Marion will require substantial attention from the
Company's management team. The diversion of management's attention, as well as
any other difficulties which may be encountered in the transition and
integration process, could have a material adverse effect on the revenue and
operating results of the Company. There can be no assurance that the Company
will be able to integrate the operations of the Company and Marion successfully
or the extent to which the Company will be able to realize the potential
benefits of the Marion Acquisition or the timing of any such benefits. Failure
to achieve a substantial portion of these benefits within the time frame
expected by the Company could have a material adverse effect on the Company,
including its ability to make payments on the Notes. See "Unaudited Pro Forma
Combined Condensed Financial Statements" and "Business -- Integration
Strategies."
 
CYCLICAL NATURE OF INDUSTRY; POTENTIAL FLUCTUATIONS IN OPERATING RESULTS
 
     The Company's business is cyclical in nature and sensitive to changes in
general economic conditions, including fluctuations in market prices for coal
and energy alternatives to coal, copper, iron ore, and phosphate. These
businesses are in turn influenced by a variety of factors beyond the Company's
control, including interest rates and general economic conditions throughout the
world. As a result of this cyclicality, the Company has experienced, and in the
future could experience, reduced net sales and margins, which may affect the
Company's ability to satisfy its debt service obligations, including payments on
the Notes, on a timely basis. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
     The Company's net sales and operating results may fluctuate significantly
from period to period. Given the large sales price of the Company's machinery,
one or a limited number of machines may account for a substantial portion of net
sales in any particular period. As a result, in any given period, a single
customer may account for a large percentage of net sales. Losing the business of
any of its top customers could have an adverse effect upon the results of
operations and financial condition of the Company. Although the Company
recognizes net sales on a percentage-of-completion basis for new machines, the
timing of one or a small number of contracts
 
                                       15
<PAGE>   22
 
in any particular period may nevertheless affect operating results. In addition,
net sales and gross profit may fluctuate depending upon the size and the
requirements of the particular contracts entered into in that period. As a
result of these and other factors, the Company may experience significant
fluctuations in net sales and operating results in future periods. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
EFFECTIVE SUBORDINATION
 
     The Existing Notes and the Guarantees are not, and the Exchange Notes will
not be, secured and are, or will be, effectively subordinated to secured
obligations of Bucyrus and the Guarantors, respectively, to the extent of the
assets securing such obligations. The obligations of Bucyrus under the Revolving
Credit Facility are secured by a pledge of the capital stock of certain of
Bucyrus' subsidiaries, by a security interest in substantially all of the
property of Bucyrus and certain of its subsidiaries, including inventory,
equipment, receivables, and intangible assets such as licenses, trademarks, and
customer lists. If Bucyrus becomes insolvent or is liquidated, or if payment
under the Revolving Credit Facility is accelerated, the lenders under the
Revolving Credit Facility would be entitled to exercise the remedies available
to a secured lender under applicable law and pursuant to the Revolving Credit
Facility. Accordingly, such lenders will have a prior claim on such assets of
the Company and such subsidiaries over the Noteholders.
 
     The Existing Notes are, and the Exchange Notes will be, effectively
subordinated to all existing and future liabilities, including Indebtedness, of
Bucyrus' foreign subsidiaries. Claims of creditors of such subsidiaries,
including trade creditors, will generally have priority as to the assets of such
subsidiaries over the claims of Bucyrus and the holders of Bucyrus'
Indebtedness, including the Notes.
 
FOREIGN OPERATIONS
 
     Both the Company and Marion have significant operations in foreign
countries and derive a substantial portion of their net sales from foreign
markets. During 1996, $279.6 million, or approximately 75%, of the Company's pro
forma net sales were generated outside the United States.
 
     The value of the Company's foreign sales and earnings may vary with
currency exchange rate fluctuations. To the extent that the Company does not
take steps to mitigate the effects of changes in relative values, changes in
currency exchange rates could have an adverse effect upon the Company's results
of operations, which in turn could adversely affect the Company's ability to
meet its debt service obligations, including payments on the Notes. Furthermore,
international manufacturing, sales and service operations are subject to other
inherent risks, including labor unrest, political instability, restrictions on
transfer of funds (including by dividend), export duties and quotas, domestic
and foreign customs and tariffs, current and changing regulatory environments,
difficulty in obtaining distribution support, and potentially adverse tax
consequences. There can be no assurance that these factors will not have a
material adverse effect on the Company or its international operations or sales.
See "Business -- Foreign Operations."
 
COMPETITION
 
     The Company operates in a highly competitive environment. It competes
directly and indirectly with other manufacturers of draglines, mining shovels
(both electric and hydraulic), and rotary blast hole drills, as well as with
manufacturers of parts and components for all of the foregoing. Some of the
Company's competitors are larger, have greater financial resources, and may be
less leveraged than the Company. See "Business -- Competition."
 
                                       16
<PAGE>   23
 
PRINCIPAL SHAREHOLDER
 
     As a result of the AIP Merger, AIPAC, which is controlled by AIP, is the
sole shareholder of Bucyrus and has the ability to designate all of the
Directors of Bucyrus. Currently all of the directors of Bucyrus are designees of
AIPAC. See "Principal Shareholders," "Management," and "Acquisition of the
Company by AIP." AIPAC, and indirectly AIP, are in a position to direct the
management and affairs of the Company and may cause the Company to enter into
transactions that in their judgment could ultimately enhance shareholder value
but involve risks to the holders of the Notes.
 
ENVIRONMENTAL AND RELATED MATTERS
 
     The Company's operations and properties are subject to a broad range of
federal, state, local and foreign laws and regulations relating to environmental
matters, including laws and regulations governing discharges into the air and
water, the handling and disposal of solid and hazardous substances and wastes,
and the remediation of contamination associated with releases of hazardous
substances at Company facilities and at off-site disposal locations. These laws
are complex, change frequently and have tended to become more stringent over
time.
 
     Based upon the Company's experience to date, the Company believes that the
future cost of compliance with existing environmental laws, regulations and
ordinances (or liability for known environmental claims) will not have a
material adverse effect on the Company's business, financial condition and
results of operations. Nevertheless, future events, such as compliance with more
stringent laws or regulations, or more vigorous enforcement policies of
regulatory agencies or stricter or different interpretations of existing laws
could require additional expenditures by the Company which may be material.
Certain laws, such as the Comprehensive Environmental Response, Compensation and
Liability Act ("CERCLA" or "Superfund") provide for strict joint and several
liability for investigation and remediation of spills and other releases of
hazardous substances. Such laws may apply to conditions at properties presently
or formerly owned or operated by an entity or its predecessors, as well as to
conditions at properties at which wastes or other contamination attributable to
an entity or its predecessors come to be located. The Company is currently a
Potentially Responsible Party ("PRP") under CERCLA at several sites. While no
assurance can be given, the Company believes that expenditures for compliance
and remediation will not have a material effect on its capital expenditures,
earnings or competitive position. See "Business -- Environmental Matters."
 
LABOR RELATIONS
 
     As of July 31, 1997, 418 of the 797 employees at the Company's South
Milwaukee facility were represented by the United Steelworkers of America Union.
In May 1997, the union ratified a new four-year agreement with the Company that
expires on April 30, 2001. Although the Company believes that its relations with
its employees are satisfactory, a dispute between the Company and its employees
could have a material adverse effect on the Company. See "Business --
Employees."
 
FRAUDULENT CONVEYANCE CONSIDERATIONS
 
     Various fraudulent conveyance laws have been enacted for the protection of
creditors and may be utilized by a court to subordinate or void the Notes (and
payments of principal and/or interest in respect thereof could be voided and
recovered) or the Guarantees in favor of other existing or future creditors of
the Company or the Guarantors.
 
     Proceeds of the Private Offering were used, in part, to pay the
consideration for the Common Stock, options to purchase Common Stock and stock
appreciation rights with respect to the Common Stock in the AIP Tender Offer
and/or the AIP Merger. If a court in a lawsuit brought by an unpaid creditor or
representative of creditors, such as a trustee in bankruptcy or Bucyrus, or any
Guarantor, as a debtor-in-possession, were to find under relevant federal or
state fraudulent conveyance statutes that Bucyrus or any Guarantor did not
receive fair consideration or reasonably
 
                                       17
<PAGE>   24
 
equivalent value for issuing the Notes or its Guarantee, as the case may be, and
that, at the time of such incurrence, Bucyrus or such Guarantor (i) was
insolvent; (ii) was rendered insolvent by reason of such incurrence or grant;
(iii) was engaged or about to engage in a business or transaction for which the
assets remaining with Bucyrus or such Guarantor, as the case may be, constituted
unreasonably small capital; or (iv) intended to incur, or believed or reasonably
should have believed that it would incur, debts beyond its ability to pay such
debts as they become due, then such court, subject to applicable statutes of
limitation, could void the Notes or such Guarantor's obligations under its
Guarantee, as the case may be, subordinate the Notes or such Guarantee to other
indebtedness of Bucyrus or such Guarantor, as the case may be, or take other
action detrimental to the holders of Notes.
 
     The measure of insolvency for these purposes will depend upon the governing
law of the relevant jurisdiction. Generally, however, a company will be
considered insolvent for these purposes if the sum of that company's debts is
greater than the fair value of all of that company's property or if the present
fair salable value of that company's assets is less than the amount that will be
required to pay its probable liability on its existing debts as they become
absolute and matured. Moreover, regardless of solvency, a court could void an
incurrence of indebtedness, including the Notes and the Guarantees, if it
determined that such transaction was made with the intent to hinder, delay or
defraud creditors. In addition, a court could subordinate the indebtedness,
including the Notes and the Guarantees, to the claims of all existing and future
creditors on similar grounds.
 
     There can be no assurance as to what standard a court would apply in order
to determine whether Bucyrus or a Guarantor was "insolvent" upon consummation of
the sale of the Notes or whether one or more Guarantors were "insolvent" upon
the incurrence of the Guarantees or that, regardless of the method of valuation,
a court would not determine that Bucyrus or one or more Guarantors was insolvent
as a result of the foregoing.
 
     Based upon financial and other information currently available to it,
management of the Company believes that the indebtedness represented by the
Notes has been incurred for proper purposes and in good faith. Certain courts
have held, however, that a company's purchase of its own capital stock does not
constitute reasonably equivalent value or fair consideration for incurring
indebtedness. By extension, the retirement of options to purchase, or stock
appreciation rights in respect thereof, capital stock of a company may also be
viewed as not constituting reasonably equivalent value or fair consideration to
the company. The Company believes that it (i) is solvent and will continue to be
solvent after issuing the Exchange Notes, (ii) will have sufficient capital for
carrying on the business it intends to conduct after such issuance, and (iii)
will be able to pay its debts as they become due. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations -- Liquidity and
Capital Resources." There can be no assurance, however, that a court would
concur with such beliefs and positions.
 
PURCHASE OF NOTES ON CHANGE OF CONTROL
 
     Upon a Change of Control, Bucyrus is required, subject to certain
conditions, to offer to purchase all outstanding Notes at 101% of the aggregate
principal amount thereof, plus accrued and unpaid interest and liquidated
damages, if any, to the date of purchase. The source of funds for any such
purchase would be Bucyrus' available cash or cash generated from other sources,
including borrowings, sales of assets, sales of equity or funds provided by a
new controlling person. A Change of Control likely would constitute an event of
default under the Revolving Credit Facility that would permit the lenders to
accelerate the debt under the Revolving Credit Facility. In such event, Bucyrus
likely would attempt to refinance the indebtedness outstanding under the
Revolving Credit Facility and the Notes. There can be no assurance that
sufficient funds will be available at the time of any Change of Control to make
any required purchases of Notes tendered and to repay indebtedness under the
Revolving Credit Facility. See "Revolving Credit Facility" and "Description of
the Notes -- Change of Control."

<PAGE>   25
 
ABSENCE OF A PUBLIC MARKET FOR THE NOTES
 
     The Exchange Notes are being offered to the holders of Existing Notes. The
Existing Notes were originally issued on the Issue Date to the Initial
Purchasers pursuant to Section 4(2) of the Securities Act. The Company has been
advised that the Existing Notes subsequently have been resold to (i) qualified
institutional buyers as defined in Rule 144A ("Qualified Institutional Buyers"
or "QIBs") in reliance on, and subject to the restrictions imposed pursuant to,
Rule 144A, and (ii) certain non-U.S. persons outside the United States of
America in accordance with Regulation S. The Existing Notes beneficially owned
by Qualified Institutional Buyers are eligible for trading in the Private
Offering, Resale and Trading through Automated Linkages ("PORTAL") Market, which
is the National Association of Securities Dealers' screen-based automated market
for trading of securities eligible for resale under Rule 144A.
 
     To the extent that Existing Notes are tendered and accepted in the Exchange
Offer, the trading market for the remaining untendered or tendered but not
accepted Existing Notes could be adversely affected. The Exchange Notes will
constitute a new issue of securities, have no established trading market and may
not be widely distributed. Although the Initial Purchasers have informed the
Company that they currently intend to make a market in the Exchange Notes, they
are not obligated to do so and may discontinue market making at any time without
notice. The Company does not intend to list the Notes on any national securities
exchange or to seek the admission thereof to trading in The Nasdaq National
Market. Accordingly, there can be no assurance as to the development or
liquidity of any market for either Exchange Notes or the Existing Notes. If a
market does develop, the Notes may trade at a discount from their principal
amount, and the price of the Notes may fluctuate depending on many factors
including, but not limited to, prevailing interest rates, the Company's
operating results and the market for similar securities, and liquidity may
therefore be limited. If a market for the Notes does not develop, purchasers may
be unable to resell such securities for an extended period of time, if at all.
 
                               THE EXCHANGE OFFER
 
PURPOSE
 
     In connection with the initial sale of the Existing Notes, Bucyrus agreed,
subject to certain conditions, to use its best efforts to conduct the Exchange
Offer. Bucyrus' purpose in making the Exchange Offer is to comply with such
agreement and to avoid the payment of Liquidated Damages (as defined) which
would occur if the Exchange Offer were not duly and timely consummated. See
"Exchange Offer; Registration Rights." The full terms of Bucyrus' obligations
with respect to the Exchange Offer are set forth in the Registration Agreement
which has been filed as an exhibit to the Registration Statement of which this
Prospectus is a part. The Exchange Offer should provide holders of Existing
Notes, which are subject to trading restrictions, with the ability to effect,
for federal income tax purposes, a tax-free exchange of such Existing Notes for
Exchange Notes that should not be subject to such restrictions.
 
     Based on interpretations by the staff of the Commission, as set forth in
no-action letters issued to third parties, the Company believes that the
Exchange Offer will provide holders of Existing Notes with Exchange Notes that
will generally be freely transferable by holders thereof (other than any holder
who is an "affiliate" of Bucyrus within the meaning of Rule 405 under the
Securities Act), who may offer for resale, resell or otherwise transfer such
Exchange Notes without complying with the registration and prospectus delivery
provisions of the Securities Act, provided that such Exchange Notes are acquired
in the ordinary course of each such holder's business and such holders are not
engaged in, and do not intend to engage in, a distribution of such Exchange
Notes and have no arrangement or understanding with any person to participate in
a distribution of such Exchange Notes. Bucyrus has not sought, and does not
intend to seek, a no-action letter from the Commission with respect to the
effects of the Exchange Offer. By tendering Existing Notes and
 
                                       19
<PAGE>   26
 
executing the Letter of Transmittal, the holder thereof shall represent and
agree that (i) it is neither an affiliate of Bucyrus nor a broker-dealer
tendering Existing Notes acquired directly from Bucyrus for its own account,
(ii) it acquired the Exchange Notes in the ordinary course of its business and
(iii) it is not engaged in, and does not intend to engage in, a distribution of
the Exchange Notes and it has no arrangement or understanding to participate in
a distribution of Exchange Notes. Holders of Existing Notes who participate in
the Exchange Offer should be aware that, except in the case of certain
broker-dealers as described below, if they accept the Exchange Offer for the
purpose of participating in a distribution of the Exchange Notes, they cannot
rely on such interpretations by the staff of the Commission and must comply with
the registration and prospectus delivery requirements of the Securities Act.
 
     Each broker-dealer that receives Exchange Notes for its own account in
exchange for Existing Notes, where such Existing Notes were acquired by such
broker-dealer as a result of market-making activities or other trading
activities, must acknowledge that it will deliver a Prospectus with any resale
of such Exchange Notes. See "Plan of Distribution."
 
TERMS OF THE OFFER
 
     Bucyrus hereby offers, upon the terms and conditions set forth herein and
in the related Letter of Transmittal, to exchange Exchange Notes for a like
principal amount of outstanding Existing Notes. An aggregate of $150 million
principal amount of Existing Notes are outstanding. The Exchange Offer is not
conditioned upon any minimum principal amount of Existing Notes being tendered.
 
     The Exchange Offer will expire at 5:00 p.m., New York City time, on
December   , 1997 unless extended. The term "Expiration Date" means 5:00 p.m.,
New York City time, on December   , 1997, unless Bucyrus, in its sole
discretion, notifies the Exchange Agent that the period of the Exchange Offer
has been extended, in which case the term "Expiration Date" means the latest
time and date on which the Exchange Offer is so extended will expire. See
"-- Expiration and Extension."
 
     In addition, Bucyrus reserves the right to waive any condition or otherwise
amend the Exchange Offer prior to the acceptance of tendered Existing Notes. If
any amendment by Bucyrus of the Exchange Offer or waiver by Bucyrus of any
condition thereto constitutes a material change in the information previously
disclosed to the holders of Existing Notes, Bucyrus will, in accordance with the
applicable rules of the Commission, promptly disseminate disclosure of such
change in a manner reasonably calculated to inform such holders of such change.
If it is necessary to permit an adequate dissemination of information regarding
such material change, Bucyrus will extend the Exchange Offer to permit an
adequate time for holders of Existing Notes to consider the additional
information.
 
CERTAIN EFFECTS OF THE EXCHANGE OFFER
 
     Because the Exchange Offer is for any and all Existing Notes, the number of
Existing Notes tendered and exchanged in the Exchange Offer will reduce the
principal amount of Existing Notes outstanding. As a result, the liquidity of
any remaining Existing Notes may be substantially reduced. The Existing Notes
beneficially owned by QIBs are currently eligible for sale pursuant to Rule 144A
through the PORTAL System. Because Bucyrus anticipates that most holders of
Existing Notes will elect to exchange such Existing Notes for Exchange Notes due
to the absence of restrictions on the resale of Exchange Notes under the
Securities Act, Bucyrus anticipates that the liquidity of the market for any
Existing Notes remaining after the consummation of the Exchange Offer may be
substantially limited.
 
     The Existing Notes that are not exchanged for Exchange Notes pursuant to
the Exchange Offer will remain restricted securities under the Securities Act.
Accordingly, such Existing Notes may be resold only (i) to Bucyrus, (ii)
pursuant to a registration statement that has been declared effective under the
Securities Act, (iii) for so long as the Existing Notes are eligible for resale
pursuant to
 
                                       20
<PAGE>   27
 
Rule 144A, to a person it reasonably believes is a Qualified Institutional Buyer
that purchases for its own account or for the account of a Qualified
Institutional Buyer to whom notice is given that the transfer is being made in
reliance on Rule 144A, (iv) pursuant to offers and sales to non-U.S. persons
that occur outside the United States within the meaning of Regulation S, (v) to
an institutional "accredited investor" (as defined in Rule 501(a)(1), (2), (3)
or (7) of Regulation D under the Securities Act and referred to in this
Prospectus as an "Institutional Accredited Investor") that is acquiring the
security for its own account or for the account of such an Institutional
Accredited Investor for investment purposes and not with a view to, or for offer
or sale in connection with, any distribution in violation of the Securities Act
or (vi) pursuant to any other available exemption from the registration
requirements of the Securities Act, subject in each of the foregoing cases (a)
to any requirement of law that the disposition of its property or the property
of such investor account or accounts be at all times within its or their control
and (b) to compliance with any applicable state or other securities laws. After
the Exchange Offer is completed, holders of Existing Notes will not have certain
registration rights under the Registration Agreement. See "--Termination of
Certain Rights."
 
EXPIRATION AND EXTENSION
 
     The Exchange Offer will expire at 5:00 p.m., New York City time, on
December   , 1997, unless extended by Bucyrus. The Exchange Offer may be
extended by oral or written notice from Bucyrus to the Exchange Agent at any
time or from time to time, on or prior to the date then fixed for the expiration
of the Exchange Offer. Notwithstanding any extension of the Exchange Offer, if
the Exchange Offer is not consummated by March 23, 1998, Liquidated Damages (as
defined) will accrue. See "Exchange Offer; Registration Rights." Public
announcement of any extension of the Exchange Offer will be timely made by
Bucyrus, but, unless otherwise required by law or regulation, Bucyrus will not
have any obligation to communicate such public announcement other than by making
a release to the Dow Jones News Service.
 
ACCRUED INTEREST
 
     Holders of Existing Notes that are accepted for exchange will not receive
any accrued interest thereon. However, each Exchange Note will bear interest
from the most recent date on which interest has been paid on the corresponding
Existing Note, or, if no interest has been paid, from September 24, 1997.
 
CONDITIONS
 
     Notwithstanding any other provisions of the Exchange Offer, or any
extension of the Exchange Offer, the Company will not be required to cause the
issuance of Exchange Notes in respect of any validly tendered Existing Notes not
accepted and, prior to the acceptance of tendered Existing Notes, may terminate
the Exchange Offer (by oral or written notice to the Exchange Agent and by
timely public announcement communicated, unless otherwise required by applicable
law or regulation, by making a release to the Dow Jones News Service) or,
subject to compliance with the applicable rules of the Commission, delay the
acceptance of the tendered Existing Notes, if any material change occurs which
is likely to affect the Exchange Offer, including, but not limited to, the
following:
 
          (i) there shall occur (a) any general suspension of or general
     limitation on prices for, or trading in, securities on any national
     securities exchange or in the over-the-counter market, (b) any limitation
     by any governmental agency or authority which may adversely affect the
     ability of the Company to complete the transactions contemplated by the
     Exchange Offer, (c) a declaration of a banking moratorium or any suspension
     of payments in respect of banks in the United States or any limitation by
     any governmental agency or authority which adversely affects the extension
     of credit or (d) a commencement of a war, armed hostilities or other
     similar international calamity directly or indirectly involving the United
     States, or, in the case of any of
 
                                       21
<PAGE>   28
 
     the foregoing existing at the time of the commencement of the Exchange
     Offer, a material acceleration or worsening thereof;
 
          (ii) any statute, rule or regulation shall have been proposed or
     enacted, or any action shall have been taken or proposed to be taken by any
     governmental authority which, in the sole judgment of the Company, would or
     might prohibit, restrict or delay completion of the Exchange Offer;
 
          (iii) there shall be instituted or threatened any action or proceeding
     before any court or governmental agency challenging the Exchange Offer or
     otherwise directly or indirectly relating to the Exchange Offer;
 
          (iv) there shall occur any development in any pending action or
     proceeding which, in the sole judgment of the Company, would or might
     prohibit, restrict or delay consummation of the Exchange Offer;
 
          (v) there exists, in the sole judgment of the Company, any actual or
     threatened legal impediment (including a default or prospective default
     under an agreement, indenture or other instrument or obligation to which
     the Company is a party or by which it is bound) to the completion of the
     Exchange Offer; or
 
          (vi) prior to the completion of the Exchange Offer, the Company
     determines there has been a change in law or applicable interpretation
     thereof by the staff of the Commission such that the Exchange Notes that
     would be received by holders in the Exchange Offer in exchange for Existing
     Notes would not be transferable, upon receipt, by each such holder (other
     than a holder that is an affiliate of the Company, a holder who acquires
     the Exchange Notes outside the ordinary course of such holder's business, a
     holder who is engaged in or intends to engage in a distribution of such
     Exchange Notes or a holder who has arrangements or understandings with any
     person to participate in the Exchange Offer for the purpose of distributing
     the Exchange Notes) without restriction under the Securities Act.
 
     Subject to the obligations under the Registration Agreement to use its best
efforts to complete the Exchange Offer, the Company expressly reserves the
right, at any time prior to the acceptance of tendered Existing Notes, to
terminate the Exchange Offer and not accept for exchange any Existing Notes upon
the occurrence of any of the foregoing conditions. In addition, the Company may
amend the Exchange Offer at any time prior to the acceptance of tendered
Existing Notes if any of the conditions set forth above occur. Moreover,
regardless of whether any of the foregoing conditions has occurred, the Company
reserves the right, in its reasonable discretion, to amend the Exchange Offer in
any manner prior to the acceptance of tendered Existing Notes, although it has
no current intention to do so.
 
     The foregoing conditions are for the sole benefit of the Company and may be
asserted by the Company regardless of the circumstances giving rise to any such
condition or may be waived by the Company, in whole or in part, at any time and
from time to time in its sole discretion. Any determination made by the Company
concerning an event, development or circumstance described or referred to above
will be final and binding on all parties to the Exchange Offer.
 
     In addition, the Company will not accept for exchange any Existing Notes
tendered, and no Exchange Notes will be issued in exchange for any such Existing
Notes, if at such time any stop order shall be threatened or in effect with
respect to the Registration Statement of which this Prospectus constitutes a
part or the qualification of the Indenture under the Trust Indenture Act of
1939, as amended.
 
     If the event referred to in clause (vi), above, shall occur, the Company
shall be under no continuing obligation under the Registration Agreement to
complete the Exchange Offer, but in lieu thereof will be obligated to file and
use its best efforts to secure and maintain the effectiveness
 
                                       22

under the Securities Act of a "shelf" registration statement providing for the
resale of Existing Notes. See "Exchange Offer; Registration Rights."
 
HOW TO TENDER
 
     A holder of Existing Notes may tender Existing Notes by (i) properly
completing and signing the Letter of Transmittal or a facsimile thereof (all
references in this Prospectus to the Letter of Transmittal shall be deemed to
include a facsimile thereof), having their signatures guaranteed if required,
and delivering the same, together with the Existing Notes being tendered (or a
confirmation of an appropriate book-entry transfer), to the Exchange Agent on or
prior to the Expiration Date, or (ii) requesting a broker, dealer, bank, trust
company or other nominee to effect the transaction for such holder prior to the
Expiration Date.
 
     Exchange Notes will not be issued in the name of a person other than that
of a registered holder of the Existing Notes appearing on the Note register.
 
     The Exchange Agent will establish an account with respect to the Existing
Notes at The Depository Trust Company (the "Depository") for purposes of the
Exchange Offer promptly after the date of this Prospectus, and any financial
institution which is a participant in the Depository may make book-entry
delivery of the Existing Notes by causing the Depository to transfer such
Existing Notes into the Exchange Agent's account in accordance with the
Depository's procedure for such transfer. Although delivery of Existing Notes
may be effected through book-entry transfer into the Exchange Agent's account at
the Depository, the Letter of Transmittal, with any required signature
guarantees and any other required documents, must in any case be transmitted to
and received by the Exchange Agent on or prior to the Expiration Date at the
address set forth below under "--Exchange Agent," or the guaranteed delivery
procedure described below must be complied with. Delivery of documents to the
Depository does not constitute delivery to the Exchange Agent. See "-- 
Exchanging Book-Entry Notes."
 
     THE METHOD OF DELIVERY OF EXISTING NOTES AND ALL OTHER DOCUMENTS, INCLUDING
DELIVERY THROUGH DTC, IS AT THE ELECTION AND RISK OF THE HOLDER. IF SENT BY
MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, RETURN RECEIPT REQUESTED, BE USED,
AND PROPER INSURANCE BE OBTAINED.
 
     If a holder desires to tender Existing Notes pursuant to the Exchange Offer
and such holder's Existing Notes are not immediately available or time will not
permit all of the above documents to reach the Exchange Agent prior to the
Expiration Date, or such holder cannot complete the procedure of book-entry
transfer on a timely basis, such tender may be effected if the following
conditions are satisfied:
 
          (i) such tenders are made by or through an eligible guarantor
     institution which is a member of one of the following Signature Guarantee
     Programs: The Securities Transfer Agents Medallion Program (STAMP); The New
     York Stock Exchanges Medallion Signature Program (MSP) and The Stock
     Exchanges Medallion Program (SEMP) (each, an "Eligible Institution");
 
          (ii) a properly completed and duly executed notice of guaranteed
     delivery ("Notice of Guaranteed Delivery"), in substantially the form
     provided by the Company, is received by the Exchange Agent as provided
     below on or prior to the Expiration Date; and
 
          (iii) the Existing Notes, in proper form for transfer (or confirmation
     of book-entry transfer of such Existing Notes into the Exchange Agent's
     account at the Depository as described above), together with a properly
     completed and duly executed Letter of Transmittal and all other documents
     required by the Letter of Transmittal, are received by the Exchange Agent
     within five New York Stock Exchange, Inc. trading days after the date of
     execution of such Notice of Guaranteed Delivery.
 
                                       23
<PAGE>   30
 
     The Notice of Guaranteed Delivery may be delivered by hand or transmitted
by facsimile transmission or mail to the Exchange Agent and must include a
guarantee by an Eligible Institution in the form set forth in such Notice of
Guaranteed Delivery.
 
     A tender will be deemed to have been received as of the date when the
tendering holder's duly signed Letter of Transmittal accompanied by Existing
Notes (or a timely confirmation received of a book-entry transfer of Existing
Notes into the Exchange Agent's account at the Depository) or a Notice of
Guaranteed Delivery from an Eligible Institution is received by the Exchange
Agent. Issuances of Exchange Notes in exchange for Existing Notes tendered
pursuant to a Notice of Guaranteed Delivery by an Eligible Institution will be
made only against delivery of the Letter of Transmittal (and any other required
documents) and the tendered Existing Notes (or a timely confirmation received of
a book-entry transfer of Existing Notes into the Exchange Agent's account at the
Depository) to the Exchange Agent or confirmation of the Book-Entry Transfer
Facility Automated Tender Offer Program ("ATOP") procedures set forth below. See
" -- Exchanging Book-Entry Notes."
 
     Partial tenders of Existing Notes may be made only if (i) the principal
amount tendered is equal to $1,000 or an integral multiple thereof and (ii) the
remaining untendered portion of such Existing Notes is in a principal amount of
$250,000, or any integral multiple of $1,000 in excess of such amount. Holders
tendering less than the entire principal amount of any Existing Note they hold
in accordance with the foregoing restrictions must appropriately indicate such
fact on the Letter of Transmittal accompanying the tendered Existing Note.
 
     With respect to tenders of Existing Notes, Bucyrus reserves full discretion
to determine whether the documentation is complete and generally to determine
all questions as to tenders, including the date of receipt of a tender, the
propriety of execution of any document, and any other questions as to the
validity, form, eligibility or acceptability of any tender. Bucyrus reserves the
right to reject any tender not in proper form or otherwise not valid or the
acceptance of exchange of which, in the opinion of Bucyrus's counsel, may be
unlawful or to waive any irregularities or conditions, and Bucyrus's
interpretation of the terms and conditions of the Exchange Offer (including the
instructions on the Letter of Transmittal) will be final. Bucyrus shall not be
obligated to give notice of any defects or irregularities in tenders and shall
not incur any liability for failure to give any such notice. The Exchange Agent
may, but shall not be obligated to, give notice of any irregularities or defects
in tenders, and shall not incur any liability for any failure to give any such
notice. Existing Notes shall not be deemed to have been duly or validly tendered
unless and until all defects and irregularities have been cured or waived. All
improperly tendered Existing Notes, as well as Existing Notes in excess of the
principal amount tendered for exchange, will be returned (unless irregularities
and defects are timely cured or waived), without cost to the tendering holder
(or, in the case of Existing Notes delivered by book-entry transfer within the
Depository, will be credited to the account maintained within the Depository by
the participant in the Depository which delivered such shares), promptly after
the Expiration Date.
 
     If the Letter of Transmittal is signed by a person or persons other than
the registered holder or holders of Existing Notes, such Existing Notes must be
endorsed or accompanied by appropriate powers of attorney, in either case signed
exactly as the name or names of the registered holder or holders appear on the
Existing Notes.
 
     If the Letter of Transmittal or any Existing Notes or powers of attorney
are signed by trustees, executors, administrators, guardians, attorneys-in-fact,
officers of corporations or others acting in a fiduciary or representative
capacity, such persons should so indicate when signing, and, unless waived by
the Company, proper evidence satisfactory to the Company of their authority to
so act must be submitted.

<PAGE>   31
 
EXCHANGING BOOK-ENTRY NOTES
 
     The Exchange Agent and the Depository have confirmed that any financial
institution that is a participant in the Depository may utilize ATOP to tender
Existing Notes.
 
     Any Depository participant may make book-entry delivery of Existing Notes
by causing the Depository to transfer such Existing Notes into the Exchange
Agent's account in accordance with the Depository's ATOP procedures for
transfer. However, the exchange for the Existing Notes so tendered will only be
made after timely confirmation (a "Book-Entry Confirmation") of such book-entry
transfer of Existing Notes into the Exchange Agent's account, and timely receipt
by the Exchange Agent of an Agent's Message (as such term is defined in the next
sentence) and any other documents required by the Letter of Transmittal. The
term "Agent's Message" means a message, transmitted by the Depository and
received by the Exchange Agent and forming part of a Book-Entry Confirmation,
which states that the Depository has received an express acknowledgment from a
participant tendering Existing Notes that are the subject of such Book-Entry
Confirmation that such participant has received and agrees to be bound by the
terms of the Letter of Transmittal, and that the Company may enforce such
agreement against such participant.
 
TERMS AND CONDITIONS OF THE LETTER OF TRANSMITTAL
 
     The Letter of Transmittal contains, among other things, certain terms and
conditions which are summarized below and are part of the Exchange Offer.
 
     Each holder who tenders Existing Notes (other than certain broker-dealers)
and executes the Letter of Transmittal will be required to represent and agree
that such tendering holder is neither an affiliate of Bucyrus nor a
broker-dealer tendering Existing Notes acquired directly from Bucyrus for its
own account, has acquired the Exchange Notes in the ordinary course of its
business, is not engaged in, and does not intend to engage in, the distribution
of the Exchange Notes and has no arrangement or understanding to participate in
a distribution of Exchange Notes. Each broker-dealer that receives Exchange
Notes for its own account in exchange for Existing Notes, where such Existing
Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge, among other things,
that it will deliver a Prospectus in connection with any resale of such Exchange
Notes. See "Plan of Distribution." The Letter of Transmittal states that by so
acknowledging and by delivering a prospectus, a broker-dealer will not be deemed
to admit that it is an "underwriter" within the meaning of the Securities Act.
 
     Existing Notes tendered in exchange for Exchange Notes (or a timely
confirmation of a book-entry transfer of such Existing Notes into the Exchange
Agent's account at the Depository) must be received by the Exchange Agent, with
the Letter of Transmittal and any other required documents, by 5:00 p.m., New
York City time, on or prior to December   , 1997, unless extended, or within the
time periods set forth above in " -- How to Tender" pursuant to a Notice of
Guaranteed Delivery from an Eligible Institution. The party tendering the
Existing Notes for exchange (the "Tendering Holder") shall be deemed to have
sold, assigned and transferred the Existing Notes to the Exchange Agent, as
agent of Bucyrus, and irrevocably constituted and appointed the Exchange Agent
as the Tendering Holder's agent and attorney-in-fact to cause the Existing Notes
to be transferred and exchanged. The Tendering Holder shall also warrant that it
has full power and authority to tender, exchange, sell, assign, and transfer the
Existing Notes and to acquire the Exchange Notes issuable upon the exchange of
such tendered Existing Notes, that the Exchange Agent, as agent of Bucyrus, will
acquire good and unencumbered title to the tendered Existing Notes, free and
clear of all liens, restrictions, charges and encumbrances, and that the
Existing Notes tendered for exchange are not subject to any adverse claims when
accepted by the Exchange Agent, as agent of Bucyrus. The Tendering Holder shall
also warrant that it will, upon request, execute and deliver any additional
documents deemed by Bucyrus or the Exchange Agent to be necessary or desirable
to complete the exchange, sale, assignment and transfer of the Existing Notes.
All authority conferred or agreed to be conferred in the Letter of Transmittal
by the Tendering
 
                                       25
<PAGE>   32
 
Holder will survive the death or incapacity of the Tendering Holder and any
obligation of the Tendering Holder shall be binding upon the heirs, executors,
administrators, personal representatives, trustees in bankruptcy, legal
representatives, successors and assigns of such Tendering Holder.
 
     Signature(s) on the Letter of Transmittal will be required to be guaranteed
as set forth above in " -- How to Tender." All questions as to the validity,
form, eligibility (including time of receipt) and acceptability of any tender
will be determined by Bucyrus, in its sole discretion, and such determination
will be final and binding. Unless waived by Bucyrus, irregularities and defects
must be cured by the Expiration Date.
 
WITHDRAWAL RIGHTS
 
     All tenders of Existing Notes may be withdrawn at any time prior to the
Expiration Date. To be effective, a notice of withdrawal must be timely received
by the Exchange Agent at the address set forth below under " -- Exchange Agent."
Any notice of withdrawal must specify the person named in the Letter of
Transmittal as having tendered the Existing Notes to be withdrawn. If the
Existing Notes have been physically delivered to the Exchange Agent, the
Tendering Holder must also submit the serial number shown on the particular
Existing Notes to be withdrawn. If the Existing Notes have been delivered
pursuant to the book-entry procedures set forth above under " -- How to Tender,"
any notice of withdrawal must specify the name and number of the participant's
account at the Depository to be credited with the withdrawn Existing Notes. The
Exchange Agent will return the properly withdrawn Existing Notes as soon as
practicable following receipt of the notice of withdrawal. All questions as to
the validity, including time of receipt, of notices and withdrawals will be
determined by Bucyrus, and such determination will be final and binding on all
parties.
 
ACCEPTANCE OF TENDERS
 
     Subject to the terms and conditions of the Exchange Offer, including the
reservation of certain rights by Bucyrus, Existing Notes tendered (either
physically or through book-entry delivery as described in " -- How to Tender")
with a properly executed Letter of Transmittal and all other required
documentation, and not withdrawn, will be accepted on or promptly after the
Expiration Date. At the option of the holder of an Exchange Note, such Exchange
Note may be held in the form of either (i) a certificated Exchange Note or (ii)
a beneficial interest in one or more of the Global Notes (as defined).
Beneficial interests in the Global Notes will be shown on, and transfers thereof
will be effected only through, records maintained by the Depository and its
participants. Subject to the terms and conditions of the Exchange Offer,
certificated Exchange Notes to be issued in exchange for properly tendered
Existing Notes will be mailed by the Exchange Agent promptly after the
acceptance of such tendered Existing Notes and the Exchange Notes to be issued
in the form of Global Notes will be deposited with the Depository promptly after
acceptance of the related tendered Existing Notes. Acceptance of tendered
Existing Notes will be effected by the delivery of a notice to that effect by
Bucyrus to the Exchange Agent. Subject to the applicable rules of the
Commission, Bucyrus, however, reserves the right, prior to the acceptance of
tendered Existing Notes, to delay acceptance of tendered Existing Notes upon the
occurrence of any of the conditions set forth above under the caption "--
Conditions." Bucyrus confirms that its reservation of the right to delay
acceptance of tendered Existing Notes is subject to the provisions of Rule
14e-1(c) under the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), which requires that a tender offeror pay the consideration offered or
return the tendered securities promptly after the termination or withdrawal of a
tender offer.
 
     Although Bucyrus does not currently intend to do so, if it modifies the
terms of the Exchange Offer, such modified terms will be available to all
holders of Existing Notes, whether or not their Existing Notes have been
tendered prior to such modification. Any material modification will be disclosed
in accordance with the applicable rules of the Commission and, if required, the
Exchange
 
                                       26
<PAGE>   33
 
Offer will be extended to permit holders of Existing Notes adequate time to
consider such modification.
 
     The tender of Existing Notes pursuant to any one of the procedures set
forth in "-- How to Tender" will constitute an agreement between the Tendering
Holder and Bucyrus upon the terms and subject to the conditions of the Exchange
Offer.
 
EXCHANGE AGENT
 
     Harris Trust and Savings Bank has agreed to provide certain services as
Exchange Agent for the Exchange Offer. Tendering Holders who require assistance
should contact the Exchange Agent. Letters of Transmittal and any inquiries with
respect to the Exchange Offer must be addressed to the Exchange Agent as
follows:
 
<TABLE>
<S>                            <C>                            <C>
     Delivery to other than the above address will not constitute valid
delivery.
 
SOLICITATION OF TENDERS; EXPENSES
 
     Except as described above under "-- Exchange Agent," Bucyrus has not
retained any agent in connection with the Exchange Offer and will not make any
payments to brokers, dealers or other persons for soliciting or recommending
acceptances of the Exchange Offer. Bucyrus, will, however, reimburse the
Exchange Agent for its reasonable out-of-pocket expenses in connection
therewith. Bucyrus will also pay brokerage houses and other custodians, nominees
and fiduciaries the reasonable out-of-pocket expenses incurred by them in
forwarding copies of this Prospectus and related documents to the beneficial
owners of the Existing Notes and in handling or forwarding tenders for their
customers.
 
TRANSFER TAXES
 
     Bucyrus will pay all transfer taxes, if any, applicable to the transfer of
Existing Notes to it or its order pursuant to the Exchange Offer. If, however,
Exchange Notes and/or substitute Existing Notes not exchanged are to be
delivered to, or are to be registered or issued in the name of, any person other
than the registered holder of the Existing Notes tendered, or if tendered
Existing Notes are registered in the name of any person other than the person
signing the Letter of Transmittal, or if a transfer tax is imposed for any
reason other than the transfer of Existing Notes to the Company or its order
pursuant to the Exchange Offer, the amount of any such transfer taxes (whether
imposed on the registered holder or any other person) will be payable by the
Tendering Holder. If satisfactory evidence of payment of such taxes or exemption
therefrom is not submitted with the Letter of Transmittal, the amount of such
transfer taxes will be billed directly to such Tendering Holder.
 
ACCOUNTING TREATMENT
 
     The carrying value of the Existing Notes is expected to become the carrying
value of the Exchange Notes at the time of the Exchange Offer. Accordingly, no
gain or loss for accounting purposes will be recognized. The expenses of the
Exchange Offer will be amortized over the term of the Exchange Notes.

<PAGE>   34
 
TERMINATION OF CERTAIN RIGHTS
 
     Holders of the Exchange Notes will not be entitled to certain special
rights under the Registration Agreement, which rights will terminate when the
Exchange Offer is completed. Pursuant to the Registration Agreement, the
Exchange Offer shall be deemed to be "completed" upon the occurrence of (i) the
filing and effectiveness under the Securities Act of a registration statement
relating to the Exchange Notes to be issued in the Exchange Offer, (ii) the
maintenance of such registration statement continuously effective for a period
of not less than 30 days after notice has been sent to holders of Existing Notes
and (iii) the delivery by Bucyrus in exchange for all Existing Notes that have
been duly tendered and not validly withdrawn on or prior to the Expiration Date
of Exchange Notes transferable by each holder thereof (other than a holder that
is an affiliate of Bucyrus within the meaning of Rule 405 under the Securities
Act, a broker-dealer tendering Existing Notes acquired directly from Bucyrus for
its own account, a holder who acquires the Exchange Notes outside the ordinary
course of such holder's business or a holder who is engaged in or who intends to
engage in a distribution of the Exchange Notes or who has arrangements or
understandings with any person to participate in the Exchange Offer for the
purpose of distributing the Exchange Notes) without restrictions under the
Securities Act. The rights that will terminate include the right to require the
Company (i) to file with the Commission, and use its best efforts to cause to
become effective under the Securities Act, a registration statement with respect
to the Exchange Notes and (ii) other than in certain limited circumstances, to
file with the Commission, use its best efforts to cause to become effective
under the Securities Act and keep continuously effective for a period of up to
three years a "shelf" registration statement providing for the registration of,
and the sale on a continuous or delayed basis by the holders of, Existing Notes.
 
                                USE OF PROCEEDS
 
     The Exchange Offer is intended to satisfy certain of Bucyrus's obligations
under the Registration Agreement. Bucyrus will not receive any cash proceeds
from the issuance of the Exchange Notes offered hereby. In consideration for
issuing the Exchange Notes as contemplated in this Prospectus, Bucyrus will
receive in exchange Existing Notes in like principal amount, the form and terms
of which are identical in all material respects to the form and terms of the
Exchange Notes, except as otherwise described herein. The Existing Notes
surrendered in exchange for the Exchange Notes will be retired and canceled and
cannot be reissued. Accordingly, issuance of the Exchange Notes will not result
in any increase in the indebtedness of Bucyrus.
 
     The proceeds to Bucyrus for the sale of the Existing Notes were
approximately $145.5 million, net of Initial Purchasers' discount. The net
proceeds to Bucyrus from the sale of the Existing Notes were used to purchase or
redeem 100% of the Company's 10.5% Secured Notes due December 14, 1999 (the
"Secured Notes") and to refinance indebtedness incurred in connection with the
Marion Acquisition and the AIP Merger and fees and expenses related thereto.

                       ACQUISITION OF THE COMPANY BY AIP
 
     On August 21, 1997, Bucyrus entered into the AIP Agreement with AIPAC,
which is wholly owned by AIP, and BAC, a wholly-owned subsidiary of AIPAC.
Pursuant to the AIP Agreement, on August 26, 1997, BAC commenced an offer to
purchase for cash 100% of the Common Stock at a price of $18.00 per share (the
"AIP Tender Offer").
 
     Following consummation of the AIP Tender Offer, and the satisfaction of
certain conditions set forth in the AIP Agreement, on September 26, 1997, BAC
merged with and into Bucyrus, and each shareholder of Bucyrus received $18.00 in
cash for each share of Common Stock (the "AIP Merger"). Bucyrus is the surviving
entity following the AIP Merger and AIPAC is its sole shareholder. The AIP
Merger was accomplished without submission to a shareholder vote, as permitted
under Delaware law.
 
     The consideration in the AIP Tender Offer and the AIP Merger was funded by
(i) a $143.0 million cash common equity contribution from AIP (the "AIP Equity
Contribution"); and (ii) a loan to BAC from, or arranged by, AIP (the "AIP
Bridge Loan"). Upon consummation of the AIP Merger, the AIP Bridge Loan was
repaid, and the consideration in the AIP Merger was paid, with a portion of the
proceeds from the Private Offering.
 
     All issued and outstanding restricted stock was purchased in the AIP Tender
Offer. In addition, all issued and outstanding stock options and SARs were
cancelled, and regardless of whether such stock options or SARs had then vested
or were exercisable, each holder of stock options or SARs received cash per
share equal to $18.00 less the "strike price" of such stock options or SARs.
 
     Following consummation of the AIP Merger, Robert L. Purdum, an operating
partner of AIP and former Chairman, President and Chief Executive Officer of
Armco Inc., is expected to become the Company's Non-Executive Chairman of the
Board. Although no specific arrangements are in place, AIP presently intends to
offer the Company's executive officers the opportunity to own up to 10% of the
Company's equity through a combination of direct investments and option
programs.

                     UNAUDITED PRO FORMA COMBINED CONDENSED
                              FINANCIAL STATEMENTS
 
     The Unaudited Pro Forma Combined Condensed Statements of Operations of the
Company for the year ended December 31, 1996, and the six months ended June 30,
1997 (the "Pro Forma Statements of Operations"), and the Unaudited Pro Forma
Combined Condensed Balance Sheet of the Company as of June 30, 1997 (the "Pro
Forma Balance Sheet" and together with the Pro Forma Statements of Operations,
the "Pro Forma Financial Statements"), have been prepared to illustrate the
estimated effect of the Transactions. The Pro Forma Financial Statements are
based on certain estimates and assumptions made by the management of the Company
as to the combined operations of the Company and Marion which the Company
believes to be reasonable. The Pro Forma Financial Statements do not purport to
be indicative of the results of operations or financial position of the Company
and Marion that actually would have been obtained had the Transactions been
completed as of the assumed dates, or to project the results of operations or
financial position of the Company for any future date or period.
 
     The Pro Forma Balance Sheet gives pro forma effect to the Transactions as
if they had occurred on June 30, 1997. The Pro Forma Statements of Operations
give pro forma effect to the Transactions as if they had occurred on January 1,
1996. For purposes of the Pro Forma Statements of Operations for the year ended
December 31, 1996, Marion's historical Statement of Operations for the fiscal
year ended October 31, 1996, was combined with the Company's historical
Statement of Operations for the year ended December 31, 1996. For purposes of
the Pro Forma Statement of Operations for the six months ended June 30, 1997,
Marion's historical Statement of Operations for the six months ended June 30,
1997, was combined with the Company's historical Statement of Operations for the
six months ended June 30, 1997. Marion's results for the months of November and
December 1996 are not included in these Pro Forma Statements of Operations.
Marion's net sales and net loss for these two months were $9.5 million and $1.6
million, respectively. The Pro Forma Statements of Operations have been prepared
assuming retention of all of the Company's and Marion's net sales. See "Risk
Factors -- Realization of Benefits of the Marion Acquisition; Integration of
Marion."
 
     The Marion Acquisition and the AIP Merger will be accounted for by the
purchase method of accounting. Under purchase accounting, the total purchase
price will be allocated to the tangible and intangible assets and liabilities
assumed based upon their respective fair values as of the closing of the Marion
Acquisition and the AIP Merger, respectively, based on valuations and studies
which are not yet available. A preliminary allocation of each purchase price has
been made to major categories of assets and liabilities in the accompanying Pro
Forma Financial Statements based on available information. The actual allocation
of the purchase prices and resulting effects on income from operations may
differ significantly from the pro forma amounts included herein. These pro forma
adjustments represent management's preliminary determination of purchase
accounting adjustments and are based upon available information and certain
assumptions that management believes to be reasonable. A balance sheet will be
prepared with respect to Marion's balance sheet as of the date of such closing,
on which the post-closing purchase price adjustment will be based. Management
does not expect that differences between the preliminary and final purchase
price allocation will have a material impact on the Company's financial position
and/or results of operations.
 
     The Pro Forma Financial Statements should be read in conjunction with the
financial statements of the Company and of Marion, and the related notes
thereto, included elsewhere in this Prospectus. See also "Risk Factors --
Realization of Benefits of the Marion Acquisition; Integration of Marion" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
     For purposes of the Pro Forma Financial Statements, the "Marion
Acquisition" includes the Company's acquisition of Marion and the financing
effected to consummate that acquisition, and the "AIP Merger" includes the
acquisition of the Company by AIP and the Private Offering.

(10) The adjustments reflect the write-up to fair market value.
 
      - Inventory has been adjusted to its fair value as required by Accounting
        Principles Board Opinion No. 16. This adjustment primarily relates to
        finished parts which are being valued at their selling price, less cost
        to sell, less a selling profit. As such inventory is sold, this
        adjustment to fair value will be charged to cost of products sold. The
        Company expects the inventory to be sold over a one year period.
 
      - Goodwill is expected to be amortized over 30 years.
 
      - Intangible assets consist of engineering drawings and bill of material
        listings and are expected to be amortized over 20 years.
 
      - Plant and equipment will be amortized over the estimated useful lives of
        the respective assets using the straight-line method for financial
        reporting purposes. Estimated useful lives are expected to be 20 years
        for buildings and improvements and 10 years for machinery and equipment.
 
      - The Company intends to review its property, plant and equipment and
        intangible assets and obtain appraisals of these assets in order to
        determine what revisions, if any, should be made to individual accounts.
        The Company does not expect the appraised values to be materially
        different than the values assigned in these pro forma financial
        statements.

     As part of the purchase contract, the Company did not acquire the
     manufacturing facility of Marion. The elimination of direct costs related
     to this facility, including maintenance, security, taxes, insurance, etc.
     results in reductions of approximately $2,239 and $1,120 for the year ended
     December 31, 1996 and the six months ended June 30, 1997, respectively.
     This does not include depreciation savings reflected in the table above.
 
     Also as part of the purchase contract, the Company hired only specifically
     identified Marion employees which reflected a department-by-department
     evaluation of personnel required to handle the workload. Various
     subsidiaries of Global have retained all liabilities related to employees
     not permanently hired by the Company. The elimination of salaries and
     benefits from administrative personnel in the fixed manufacturing
     departments (plant management, purchasing, industrial relations, quality
     assurance, etc.) who have not been hired results in savings of $1,773 and
     $886 for the year ended December 31, 1996 and the six months ended June 30,
     1997, respectively. An additional $974 and $487 for the year ended December
     31, 1996 and the six months ended June 30, 1997, respectively, of
     duplicative nonpayroll costs related to manufacturing (corporate
     allocations, travel costs, outside consultants, and other manufacturing
     items) have been identified.

    savings are related to reduced direct labor costs, engineering and marketing

      Inventory has been adjusted to its fair value as required by Accounting
      Principles Board Opinion No. 16. This adjustment primarily relates to
      finished parts which are being valued at their selling price, less cost to
      sell, less a selling profit. As such inventory is sold, this adjustment to
      fair value will be charged to cost of products sold.

      There is no pro forma interest expense adjustment reflected for the Bridge
      Loan as it was repaid from the sale of the Existing Notes.
 
      The impact of a 1/8 of 1% change in the interest rate on the Notes
      approximates $188 per annum. Assuming an interest rate of 9 3/4%, interest
      expense would have been $14,625 for the fiscal year ended December 31,
      1996, and $7,313 for the six months ended June 30, 1997.

                             (DOLLARS IN THOUSANDS)
 
 (8) Pro forma income taxes have been provided at local statutory rates by tax
     jurisdiction. For the Marion Acquisition, income taxes provided on U.S.
     operations are offset by pre-bankruptcy net operating loss carryforwards.
     The benefit of such net operating loss carryforwards would be reflected as
     a reduction of intangibles rather than the tax provision. As a result of
     the AIP Merger, the tax benefit on U.S. operating losses has been
     completely offset by valuation allowances due to uncertainty as to their
     realization and the previous pro forma provision for the Marion Acquisition
     is eliminated. This results in an overall net income tax provision for pro
     forma purposes which primarily relates to taxes on foreign income.
 
 (9) As a result of the AIP Merger, there are 1,000 outstanding shares of Common
     Stock, all of which are owned by AIPAC; therefore, net loss per share of
     Common Stock is not meaningful.
 
(10) For purposes of this Prospectus (other than "Description of the Notes"),
     "EBITDA" is defined as earnings (loss) before (i) income taxes; (ii)
     interest expense; (iii) extraordinary gain; (iv) depreciation; (v)
     amortization; (vi) non-cash stock compensation; (vii) loss (gain) on sale
     of fixed assets; (viii) restructuring expenses; (ix) reorganization items;
     (x) inventory fair-value adjustment charged to cost of products sold; (xi)
     the AIP Management Fee, which is subordinated to the Notes and was not
     incurred by the Company until after the AIP Merger was consummated; and
     (xii) in 1995 only, a non-cash charge related to the scrapping and disposal
     of excess inventory related to certain older and discontinued machine
     models. See "Management's Discussion and Analysis of Financial Condition
     and Results of Operations -- EBITDA." Since cash flow from operations is
     very important to the Company's future, the EBITDA calculation provides a
     summary review of cash flow performance. EBITDA (as defined herein) should
     not be considered an alternative to operating income determined in
     accordance with GAAP as an indicator of operating performance or to cash
     flows from operating activities determined in accordance with GAAP as a
     measure of liquidity.
 
(11) On September 24, 1997, all issued and outstanding stock options and SARs
     were cancelled, and regardless of whether such stock options or SARs had
     then vested or were exercisable, each holder of stock options or SARs
     received cash per share equal to $18.00 less the "strike price" of such
     stock options or SARs. As a result, the Company incurred a one-time non-
     recurring pretax charge of approximately $7,000 in the three months ended
     September 30, 1997. Such amount was funded by a portion of the proceeds
     from the AIP Equity Contribution and is included in the sources and uses of
     funds.

             SELECTED HISTORICAL CONSOLIDATED FINANCIAL INFORMATION
 
     The following table sets forth historical financial information of the
Company as of and for the years or periods ended December 31, 1996, 1995, and
1994, and as of and for the six months ended June 30, 1997 and 1996, and for the
Predecessor Company as of and for the years or periods ended December 13, 1994,
December 31, 1993, and December 31, 1992. The Statement of Operations and
Balance Sheet information as of and for the years or periods ended December 31,
1996, 1995, and 1994, December 13, 1994, and December 31, 1993 and 1992, have
been derived from the audited consolidated financial statements of the Company.
The Statement of Operations and Balance Sheet information as of and for the six
months ended June 30, 1997 and 1996, were derived from the unaudited
consolidated financial statements of the Company, which include all adjustments
that management considers necessary to present fairly the financial results for
these interim periods, all of which were of a normal recurring nature. The
results of operations for the six month periods are not necessarily indicative
of results to be expected for the full year. This table should be read in
conjunction with "Management's Discussion and Analysis of Financial Condition
and Results of Operations" and the financial statements of the Company, and
related notes thereto, and other financial information included elsewhere in
this Prospectus.

(1) The "Predecessor Company" is B-E Holdings, Inc., the former parent of the
    Company, which was merged with and into the Company on December 14, 1994.
 
(2) For purposes of this Prospectus (other than "Description of the Notes"),
    "EBITDA" is defined as earnings (loss) before (i) income taxes; (ii)
    interest expense; (iii) extraordinary gain; (iv) depreciation; (v)
    amortization; (vi) non-cash stock compensation; (vii) loss (gain) on sale of

    inventory fair-value adjustment charged to cost of products sold; (xi) the
    AIP Management Fee, which is subordinated to the Notes and was not incurred
    by the Company until after the AIP Merger was consummated; and (xii) in 1995
    only, a non-cash charge related to the scrapping and disposal of excess
    inventory related to certain older and discontinued machine models. See
    "Management's Discussion and Analysis of Financial Condition and Results of
    Operations -- EBITDA." Since cash flow from operations is very important to
    the Company's future, the EBITDA calculation provides a summary review of
    cash flow performance. EBITDA (as defined herein) should not be considered
    an alternative to operating income as determined in accordance with GAAP as
    an indicator of operating performance or to cash flows from operating
    activities determined in accordance with GAAP as a measure of liquidity. For
    1993, EBITDA (as defined herein) also excluded the cumulative effect of
    changes in accounting principles.
 
(3) For purposes of computing the ratio of earnings to fixed charges, earnings
    consist of income from continuing operations before income taxes and fixed
    charges. Fixed charges consist of interest expense and amortization of debt
    fees. Earnings were inadequate to cover fixed charges in certain years. The
    deficiency amounted to approximately $15,807 for 1992, $39,776 for 1993,
    $21,438 for the period January 1 to December 13, 1994, $427 for the period
    December 14 to December 31, 1994, and $16,258 for 1995.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The reorganization of the Company under Chapter 11 of the Bankruptcy Code
was effective December 14, 1994. The reorganization was accounted for 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." Under the principles of fresh start reporting, total assets were recorded
at their assumed reorganization value, with the reorganization value allocated
to identifiable tangible and intangible assets on the basis of their estimated
fair value, and liabilities were adjusted to the present values of amounts to be
paid where appropriate. The consolidated financial statements for periods
subsequent to December 14, 1994, include the related amortization charges
associated with the fair value adjustments.
 
     As a result of the implementation of fresh start reporting, the
consolidated financial statements of the Company are not comparable to the
consolidated financial statements of periods prior to December 14, 1994. The
consolidated financial statements presented for prior periods are not the
Company's, but instead are those of B-E Holdings, Inc. (the "Predecessor
Company"), the former parent of the Company, which was merged with and into the
Company on December 14, 1994.
 
RESULTS OF OPERATIONS
 
  COMPARISON OF SIX MONTHS ENDED JUNE 30, 1997 AND 1996
 
     NET SALES. Net sales for the first six months of 1997 were $143.8 million
compared with $130.8 million for the first six months of 1996. Net sales of
repair parts and services were $88.6 million, which is an increase of 8% from
the first six months of 1996. The increase in repair parts and service net sales
occurred primarily at foreign locations. Net machine sales were $55.1 million,
which is an increase of 13% from the first six months of 1996. Net sales of
electric mining shovels increased 39% from the first six months of 1996. The
increase in electric mining shovel volume was primarily in copper markets. Net
sales of blast hole drills decreased 28% from the first six months of 1996.
There has been an overall decline in worldwide blast hole drill sales activity
in 1997.
 
     OTHER INCOME. Other income, which consists primarily of interest income,
was $0.6 million and $0.5 million for the six months ended June 30, 1997 and
1996, respectively.
 
     COST OF PRODUCTS SOLD. Cost of products sold for the first six months of
1997 was $116.3 million, or 81% of net sales, compared with $107.0 million, or
82% of net sales, for the first six months of 1996. The increase in gross margin
percentage was primarily due to improved machine margins.
 
     PRODUCT DEVELOPMENT, SELLING, ADMINISTRATIVE AND MISCELLANEOUS
EXPENSES. Product development, selling, administrative and miscellaneous
expenses for the first six months of 1997 were $18.3 million, or 13% of net
sales, compared with $17.9 million, or 14% of net sales, for the first six
months of 1996.
 
     INTEREST EXPENSE. Interest expense for the first six months of 1997 was
$4.0 million compared with $4.2 million for the first six months of 1996. The
Company had the option of paying interest on the Secured Notes in cash at 10.5%
or in kind (issuance of additional Secured Notes) at 13%. For the first six
months of 1997, interest was accrued at 10.5% since the Company paid this
interest in cash. For the first six months of 1996, interest was accrued at 13%
since the Company paid this interest in kind. Interest was accrued on a higher
principal balance in 1997 since all interest was paid in kind through December
31, 1996.
 
     INCOME TAXES. For the six months ended June 30, 1997, income tax expense
consists primarily of foreign taxes at applicable statutory rates and a non-cash
income tax provision on United States taxable income at applicable statutory
rates. For the component of the United States tax provision relating to tax
benefits realized from reductions in the valuation allowance established as of
 
                                       44
<PAGE>   51
 
December 14, 1994 (the date the Company reorganized under chapter 11 of the
Bankruptcy Code), a corresponding $0.5 million reduction of intangible assets
was recorded in accordance with AICPA Statement of Position 90-7, "Financial
Reporting by Entities in Reorganization Under the Bankruptcy Code." For the
component of the United States tax provision relating to reductions in the
valuation allowance established after December 14, 1994, an income tax benefit
was recorded.
 
     For the six months ended June 30, 1996, income tax expense consists
primarily of foreign taxes at applicable statutory rates. For United States tax
purposes there was a loss for which there was no income tax benefit.
 
     NET EARNINGS. Net earnings for the first six months of 1997 were $3.4
million compared with $0.9 million for the first six months of 1996. The
increase in net earnings was primarily due to increased sales volume and
improved gross margin percentage.
 
     INVENTORY, BACKLOG AND NEW ORDERS. The Company maintains a substantial
inventory of partially manufactured machines and components, as well as finished
goods inventory, primarily consisting of replacement parts, in order to reduce
lead times and respond quickly to customers' delivery requirements. Inventories
at June 30, 1997 were $74.6 million (27% of net sales for the twelve months
ended June 30, 1997), compared with $70.5 million (28% of net sales for the
twelve months ended June 30, 1996) at June 30, 1996. At June 30, 1997 and 1996,
$48.1 million and $43.4 million, respectively, were held as finished goods
inventory.
 
     The Company's consolidated backlog at June 30, 1997, was $215.8 million
compared with $158.7 million at December 31, 1996, and $184.1 million at June
30, 1996. Machine backlog at June 30, 1997, was $103.8 million, which is an
increase of 112% from December 31, 1996, and an increase of 12% from June 30,
1996. The Company received a letter of intent from BHP Coal Pty. Ltd., an
Australian mining company, to purchase a 257OWS walking dragline which is
scheduled for completion by December 31, 1999. This was expected to generate net
sales of approximately $60.2 million and is included in machine backlog at June
30, 1997. The Company currently expects that this dragline will generate net
sales of $57.5 million over the next two and one half years. Machine backlog for
electric mining shovels and blast hole drills has decreased 53% from June 30,
1996. Repair parts and service backlog at June 30, 1997 was $112.0 million,
which is an increase of 2% from December 31, 1996, and an increase of 23% from
June 30, 1996. The increase in repair parts and service backlog from June 30,
1996, was at both United States and foreign locations. Backlog includes the
dollar value of orders placed for new equipment as well as parts and services,
including estimates of revenues expected to be generated from MARCs, minus
dollars billed through manufacturing contracts, which are billed on a percentage
of completion basis. MARC revenue estimates are based on payments expected for
parts and for maintenance and operational services over the life of each
contract, some of which have terms through 2002.
 
     New orders for the first six months of 1997 were $200.8 million, which is
an increase of 2% from the first six months of 1996. New machine orders were
$109.9 million, which is an increase of 44% from the first six months of 1996.
Included in new machine orders for the first six months of 1997 was
approximately $60.2 million for the aforementioned 257OWS dragline for BHP Coal
Pty. Ltd. of Australia. New machine orders for electric mining shovels for the
first six months of 1997 were even with last year while new machine orders for
blast hole drills have decreased. There has been an overall decline in worldwide
blast hole drill orders in 1997, which was anticipated as a result of a
temporary lower demand for copper. During the first six months of 1996, a
multiple machine order was received from one South American customer in the
copper market resulting in new machine orders substantially higher than
historical levels in that six months. As a result of a decline in copper prices
in 1996 from historically high levels, demand from this market segment has
remained low. However, due to a resurgence in copper prices in late 1996, which
the Company expects to continue through 1997, there should be continued demand
from this market segment for electric mining shovels and blast hole drills.
There also was an increase in iron ore production in late 1994 that was
sustained through 1995 and 1996. The Company anticipates that some iron ore
producers will continue to replace aged electric mining shovel and blast hole
drill fleets with new
 
                                       45
<PAGE>   52
 
machines in an effort to reduce iron ore production costs. Also, price increases
for hard coking coal in 1995 and 1996 have brought new demand for machines in
western Canada and Australia in recent months. New repair parts and service
orders were $90.9 million for the first six months of 1997, which is a decrease
of 25% from the first six months of 1996. Included in new repair parts and
service orders for the first six months of 1996 were large maintenance and
repair contract orders at foreign locations.
 
  COMPARISON OF FISCAL YEARS ENDED DECEMBER 31, 1996, 1995, AND 1994
 
     NET SALES. Net sales for 1996 were $263.8 million compared with $231.9
million for 1995. Net sales of repair parts and services for 1996 were $156.4
million, which is an increase of 1% from 1995. This increase consists of an
increase in net sales at Minserco, Inc., a mining service subsidiary of the
Company, offset by a decrease in net sales of repair parts, primarily at foreign
locations. Net machine sales for 1996 were $107.4 million, which is an increase
of 40% from 1995. The increase in net machine sales was primarily due to
increased electric mining shovel shipments, primarily in copper markets.
 
     Net sales for 1995 were $231.9 million compared with $194.0 million for
1994. Net sales of repair parts and services for 1995 were $155.4 million, which
is an increase of 8% from 1994. The increase in repair parts and service net
sales was primarily due to increased repair parts net sales at foreign locations
as a result of higher demand for replacement parts. Net machine sales for 1995
were $76.5 million, which is an increase of 55% from 1994. The increase was due
to increased blast hole drill and electric mining shovel shipments, primarily in
copper, coal, and iron ore markets.
 
     OTHER INCOME. Other income, which consists primarily of interest income,
was $1.0 million, $1.3 million, and $3.1 million for 1996, 1995, and 1994,
respectively. Included in the amount for 1994 was a favorable insurance
settlement of $1.4 million.
 
     COST OF PRODUCTS SOLD. Cost of products sold for 1996 was $215.1 million,
or 82% of net sales, compared with $205.6 million, or 89% of net sales, for
1995, and $164.1 million, or 85% of net sales, for 1994. Included in cost of
products sold for 1995 and 1994 were charges of $10.1 million and $0.4 million,
respectively, as a result of the fair value adjustment to inventory. This
adjustment was made in accordance with the principles of fresh start reporting
adopted in 1994 and was charged to cost of products sold as the inventory was
sold. Also included in cost of products sold for 1995 was a charge of $4.4
million for the scrapping and disposal of excess inventory which related to
certain older and discontinued machine models. Excluding the effects of the
inventory fair value adjustment and excess inventory charge, cost of products
sold as a percentage of net sales for 1995 was 82%.
 
     PRODUCT DEVELOPMENT, SELLING, ADMINISTRATIVE, AND MISCELLANEOUS
EXPENSES. Product development, selling, administrative, and miscellaneous
expenses for 1996 were $36.5 million, or 14% of net sales, compared with $34.2
million, or 15% of net sales, in 1995, and $31.3 million, or 16% of net sales,
in 1994. The dollar increase for 1996 was primarily due to higher product
development and service costs to provide increased support to customers.
 
     INTEREST EXPENSE. Interest expense for 1996 was $8.6 million compared with
$6.3 million for 1995. The increase for 1996 was primarily due to an increase in
the interest rate on the Secured Notes from 10.5% to 13% effective December 14,
1995, for interest paid in kind by adding the interest to the principal balance.
Also, interest on the Secured Notes was accrued on a higher principal balance in
1996 since all interest was paid in kind through December 31, 1996. The Company
had the option of paying interest on the Secured Notes in cash at 10.5% or in
kind at 13%.
 
     Interest expense for 1995 was $6.3 million compared with $14.2 million for
1994. The decrease was primarily due to the exchange of unsecured debt
securities of B-E Holdings, Inc. and the Company for shares of the Company's
common stock in connection with the Company's reorganization.
 
                                       46
<PAGE>   53
 
     RESTRUCTURING EXPENSES. Restructuring expenses of $2.6 million in 1995
consist of employee severance expenses recorded to reflect the cost of reduced
employment and the severance costs related to the resignation of three officers
of the Company. See Note B to the Company's audited financial statements
appearing elsewhere herein.
 
     REORGANIZATION ITEMS. Reorganization items represent the expenses incurred
as a result of the Company's efforts to reorganize under Chapter 11 of the
Bankruptcy Code. In 1995, reorganization items consist entirely of legal and
professional fees. Reorganization items in 1994 consist of $8.0 million of legal
and professional fees, $41.1 million to adjust debt and redeemable preferred
stock to the amount of the allowed claims in the Amended Plan, and a $1.1
million write-off of capitalized financing costs. These expenses were partially
offset by $0.4 million of interest income earned from the Petition Date through
December 13, 1994, on accumulated cash balances of B-E Holdings, Inc. and the
Company.
 
     INCOME TAXES. Income tax expense consists primarily of foreign taxes at
applicable statutory rates.
 
     NET EARNINGS (LOSS). Net earnings for 1996 were $2.9 million compared with
a net loss of $18.8 million for 1995. During 1995, the Company undertook a
restructuring of its corporate headquarters and foreign subsidiaries and
completed an evaluation of its inventories and other items. The Company, in
evaluating its inventory, determined that excess levels existed for certain
older and discontinued machine models. Accordingly, a charge of $4.4 million was
made in 1995 for the eventual scrapping and disposal of this inventory.
Severance costs of $2.6 million were also recorded to reflect the cost of
reduced employment at the corporate headquarters and foreign subsidiaries, and
the resignation of three former officers. In addition, a $1.0 million charge
resulting from the reestimation of certain customer warranty reserves was
recorded in 1995, and a $0.9 million charge was made for reorganization items
related to issues continuing from the bankruptcy proceedings. Net loss for 1995
also included $8.6 million (net of income taxes) of the inventory fair value
adjustment related to fresh start reporting.
 
     Net loss for 1995 was $18.8 million compared with net earnings of $119.1
million for 1994. Included in net earnings for 1994 was an extraordinary gain on
debt discharge of $142.5 million which was partially offset by reorganization
items of $9.3 million.
 
     INVENTORY, BACKLOG, AND NEW ORDERS. Inventories at December 31, 1996, were
$70.9 million (27% of net sales) compared with $73.6 million (32% of net sales)
at December 31, 1995, and $82.4 million (42% of net sales) at December 31, 1994.
At December 31, 1996, 1995, and 1994, $44.1 million, $44.5 million, and $51.9
million, respectively, were held as finished goods inventory.
 
     The Company's consolidated backlog on December 31, 1996 was $158.7 million
compared with $118.0 million at December 31, 1995 and $72.3 million at December
31, 1994. Machine backlog at December 31, 1996 was $49.0 million, which is a
decrease of 26% from December 31, 1995. The decrease in machine backlog from
December 31, 1995 was primarily in electric mining shovel volume. Repair parts
and service backlog at December 31, 1996 was $109.7 million, which is an
increase of 110% from December 31, 1995. The increase in repair parts and
service backlog from December 31, 1995, was primarily at foreign locations and
reflect new orders related to long-term maintenance and repair contracts which
will be completed in the next three to five years.
 
     New orders for 1996 were $304.5 million, which is an increase of 10% from
1995. New machine orders for 1996 were $90.6 million, which is a decrease of 22%
from 1995. The decrease in new machine orders for 1996 was primarily in electric
mining shovel volume and represented low machine net sales activity during the
second half of 1996, primarily related to copper markets. New repair parts and
service orders for 1996 were $213.9 million, which is an increase of 33% from
1995. The increase in repair parts and service orders for 1996 was primarily due
to large maintenance and repair contract orders at foreign locations in the
first three months of 1996.

LIQUIDITY AND CAPITAL RESOURCES
 
     Working capital and current ratio are two financial measurements which
provide an indication of the Company's ability to meet its short-term
obligations. These measurements at December 31, 1994, 1995, and 1996, and June
30, 1997, were as follows:

  current liabilities)..........................     2.6 to 1     2.2 to 1     2.9 to 1      2.3 to 1
</TABLE>
 
     The decrease in the current ratio from December 31, 1996 to June 30, 1997,
was primarily due to increased liabilities in order to support increased
production of machines. The increase in working capital and the current ratio
for the year ended December 31, 1996, was primarily due to a decrease in current
liabilities to customers on uncompleted contracts and warranties and a decrease
in outstanding project financing borrowings. The decrease in working capital and
the current ratio for the year ended December 31, 1995, was primarily due to the
inventory fair value adjustment of $10.1 million being charged to cost of
products sold as the inventory was sold and an inventory obsolescence provision
of $4.4 million. See "Results of Operations -- Comparison of Fiscal Years Ended
December 31, 1996, 1995, and 1994 -- Cost of Products Sold."
 
     Equipment Assurance Limited, a subsidiary of Bucyrus, has pledged $1.1
million of its cash to secure its reimbursement obligations for outstanding
letters of credit at June 30, 1997. This collateral amount is classified as
Restricted Funds on Deposit in the Company's Consolidated Condensed Balance
Sheets.
 
     The Company believes that current levels of cash and liquidity, together
with funds generated by operations, funds available from the Revolving Credit
Facility, and other project financing arrangements will be sufficient to permit
the Company to satisfy its debt service requirements and fund operating
activities through at least 1998. The Company is subject to significant
business, economic, and competitive uncertainties that are beyond its control.
Accordingly, there can be no assurance that the Company's financial resources
will be sufficient for the Company to satisfy its debt service obligations and
fund operating activities under all circumstances. See "Revolving Credit
Facility."
 
     The Company had outstanding letters of credit and guarantees of $6.1
million at June 30, 1997. Of this amount, $4.7 million is related to the
Company's existing credit agreement with Bank One, Wisconsin, with the remainder
provided by various banks and insurance companies.
 
     At June 30, 1997, the Company had approximately $2.3 million of approved
but unspent capital appropriations. Included in this amount is the remaining
$1.2 million to be spent for a new service shop facility in Chile which is being
financed primarily with a local bank in Chile.
 
     In addition, at June 30, 1997, the Company had committed approximately $5.5
million of a planned $20.0 million machine shop tool modernization project. The
initial machine tools have been financed with operating leases and the remaining
machine tools are expected to be financed using internally generated cash,
borrowings under the Revolving Credit Facility, or operating leases.

EBITDA
 
     For purposes of this Prospectus (other than "Description of the Notes"),
"EBITDA" is defined as earnings (loss) before (i) income taxes; (ii) interest
expense; (iii) extraordinary gain; (iv) depreciation; (v) amortization; (vi)
non-cash stock compensation; (vii) loss (gain) on sale of fixed assets; (viii)
restructuring expenses; (ix) reorganization items; (x) inventory fair-value
adjustment charged to cost of products sold; (xi) the AIP Management Fee, which
is subordinated to the Notes and was not incurred by the Company until after the
AIP Merger was consummated; and (xii) in 1995 only, a non-cash charge related to
the scrapping and disposal of excess inventory related to certain older and
discontinued machine models. Since cash flow from operations is very important
to the Company's future, the EBITDA calculation provides a summary review of
cash flow performance. In addition, the Revolving Credit Facility requires the
calculation of EBITDA for certain ratios and covenants. EBITDA (as defined
herein) should not be considered an alternative to operating income determined
in accordance with GAAP as an indicator of operating performance or to cash
flows from operating activities determined in accordance with GAAP as a measure
of liquidity. The following table reconciles the Company's historical earnings
(loss) before income taxes and extraordinary gain to EBITDA (as defined herein).

                                    BUSINESS
 
GENERAL
 
     The Company (formerly known as Bucyrus-Erie Company) was incorporated in
Delaware in 1927 as the successor to a business that has been in continuous
operation since 1880. The Company is one of the world's leading manufacturers of
large-scale excavation equipment used in surface mining and other earth moving
operations, including rotary blast hole drills, electric mining shovels, and
draglines. Bucyrus machines are used throughout the world by customers who mine
coal, iron ore, copper, gold, phosphate, bauxite, oil sands, and other minerals,
as well as for land reclamation activities.
 
     An important part of the Company's business consists of aftermarket sales,
such as supplying parts, providing maintenance and repair services, providing
technical advice, as well as refurbishing and relocating older, installed
machines. The importance of aftermarket products and services in this industry
is a function of the equipment's size, expense, complexity, and long life.
Through domestic and foreign subsidiaries and overseas offices, the Company
offers a global network of comprehensive direct marketing services and
aftermarket support, which is critical to enhance machine longevity and
productivity in the field. This network caters primarily to the Company's own
installed equipment base; however, it also provides repair parts and maintenance
services for other manufacturers' equipment on a limited basis.
 
     For the fiscal year ended December 31, 1996, the Company had total net
sales of $263.8 million, comprised of $107.4 million (41%) in new equipment
sales and $156.4 million (59%) in aftermarket parts and service sales, and had
EBITDA (as defined herein) of $19.2 million. See the Company's consolidated
financial statements appearing elsewhere herein.
 
THE MARION ACQUISITION
 
     On August 26, 1997, the Company consummated the Marion Acquisition. 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 taken place on June 30, 1997. For the fiscal year ended
October 31, 1996, Marion had total net sales of $109.6 million, comprised of
$36.4 million (33%) in new equipment sales and $73.2 million (67%) in
aftermarket parts and service sales.
 
     The Company financed the Marion Acquisition and related fees and expenses
utilizing a $45.0 million unsecured bridge loan (the "Bridge Loan") provided by
a former affiliate of the Company which has been repaid in full with a portion
of the proceeds of the Private Offering.
 
     Like the Company, Marion manufactured large surface mining excavation
equipment, primarily draglines and electric mining shovels, and had a
significant aftermarket parts and services business supporting its installed
base of over 300 machines throughout the world. The aftermarket business
provides Marion-engineered components and replacement parts, as well as ongoing
electrical and mechanical service assistance on an as-required basis. Marion's
principal customers for both new machines and aftermarket parts and services
were operators of surface coal mines worldwide. Coal producers accounted for
approximately 70% of Marion's total net sales in recent years, with copper, iron
ore, phosphate rock and oil sands mining primarily accounting for the balance.
Australia, Canada, India, South Africa, and the United States were Marion's
largest geographical markets, although sales volume by country varied
substantially from year to year. In recent years, approximately 70% of Marion's
total net sales were in markets outside the United States.
 
     As described below, the Marion Acquisition provides a number of benefits to
the Company, including a substantial increase in the Company's worldwide
installed equipment base, expansion of the Company's presence in several
important markets, and the opportunity to achieve significant
 
                                       51
<PAGE>   58
 
cost savings. See "Risk Factors -- Realization of Benefits of the Marion
Acquisition; Integration of Marion."
 
          INCREASED INSTALLED EQUIPMENT BASE. The Marion Acquisition increased
     the Company's installed equipment base from approximately 900 machines to
     nearly 1,200 machines worldwide, providing the Company with significantly
     greater opportunities to market its aftermarket parts and services.
 
          EXPANDED PRESENCE IN POTENTIALLY HIGH GROWTH MARKETS. The Marion
     Acquisition provides the Company with an increased strategic presence in
     markets that are anticipated to experience substantial growth over the next
     several years, such as India and Russia, through Marion's established
     relationships with local mining interests and governmental authorities.
 
          SIGNIFICANT COST SAVINGS. The Marion Acquisition results in pro forma
     cost savings of $12.5 million for fiscal 1996 as described below, and $5.9
     million for the six months ended June 30, 1997, through the consolidation
     of manufacturing operations and the rationalization of engineering and
     administrative functions. In addition, the Company has identified an
     estimated $3.0 million in potential annual cost savings that are not
     reflected in the pro forma financial results. The cost savings reflected in
     the pro forma results and summarized below, and other anticipated cost
     savings, are based on assumptions and expectations that the Company
     believes to be reasonable, but are dependent on a variety of important
     factors. See "Risk Factors -- Realization of Benefits of the Marion
     Acquisition; Integration of Marion" and "Unaudited Pro Forma Combined
     Condensed Financial Statements."
 
          The Company is consolidating all of Marion's manufacturing operations
     into the Company's existing facilities as Marion's manufacturing facility
     was not acquired as part of the Marion Acquisition. This results in pro
     forma manufacturing cost savings of $5.0 million for fiscal 1996, and $2.5
     million for the six months ended June 30, 1997, including reductions in
     direct facility costs, fixed manufacturing administrative costs, and
     nonpayroll manufacturing costs. Cost savings of $2.2 million (excluding
     depreciation) for fiscal 1996, and $1.1 million for the six months ended
     June 30, 1997, are attributed to the elimination of direct costs related to
     the operation of Marion's primary facility in Marion, Ohio. The Company
     hired only certain of Marion's manufacturing employees, resulting in pro
     forma cost savings of $1.8 million for fiscal 1996, and $0.9 million for
     the six months ended June 30, 1997. The elimination of overhead expenses
     relating to manufacturing, including corporate allocations, travel costs,
     and consulting expenses, results in pro forma cost savings of $1.0 million
     for fiscal 1996, and $0.5 million for the six months ended June 30, 1997.
     Management believes that the Company has adequate capacity to integrate
     Marion's manufacturing operations.
 
          The Marion Acquisition also results in pro forma cost savings of $7.5
     million for fiscal 1996, and $3.4 million for the six months ended June 30,
     1997, through the consolidation of duplicative product development,
     general, and administrative functions. The Company hired only certain of
     Marion's administrative employees, with the associated elimination of
     salaries and related expenses resulting in pro forma cost savings of $4.3
     million for fiscal 1996, and $2.1 million for the six months ended June 30,
     1997. The elimination of general and administrative overhead expenses,
     primarily relating to allocated corporate expenses, results in pro forma
     cost savings of $2.2 million for fiscal 1996, and $1.2 million for the six
     months ended June 30, 1997. In late 1996, Marion eliminated various
     full-time engineering positions, resulting in pro forma cost savings of
     $1.0 million for fiscal 1996. Based on a department-by-department analysis,
     management believes that the Company's current operations, which have been
     supplemented by employees hired from Marion, will be adequately staffed for
     the foreseeable future; however, there can be no assurance that this will
     be the case.
 
          The Company expects to generate the $3.0 million in additional cost
     savings not reflected in the pro forma financial results by reducing direct
     labor costs, consolidating engineering functions, eliminating marketing
     personnel, and closing certain parts and service locations. The
 
                                       52
<PAGE>   59
 
     Company hired only certain of Marion's engineering and marketing staff
     which is expected to result in incremental annual cost saving of
     approximately $1.3 million. The Company's current engineering staff, along
     with selected individuals from Marion's engineering staff, is expected to
     be adequate to handle the engineering function. Application of the
     Company's direct labor operating efficiencies to the former Marion
     operations is expected to result in annual cost savings of approximately
     $1.3 million. Since Marion operates administrative and sales offices, parts
     warehouses and repair facilities in the same geographical areas as the
     Company, the consolidation of these functions is expected to result in
     annual cost savings of approximately $0.4 million.
 
     After giving pro forma effect to the Marion Acquisition, the Company's net
sales for fiscal 1996 would have been $373.4 million, comprised of $143.8
million (39%) of new equipment sales and $229.6 million (61%) of aftermarket
sales, and in fiscal 1996 EBITDA (as defined herein) would have been $34.0
million. See "Unaudited Pro Forma Combined Condensed Financial Statements."
 
BUSINESS STRATEGY
 
     Following an in-depth, strategic review of management and operations in
1995, the Board of Directors refocused the Company's business strategy and hired
a new management team, including Willard R. Hildebrand, President and Chief
Executive Officer, and Daniel J. Smoke, Vice President and Chief Financial
Officer. In addition, the Board increased the responsibilities of four other
senior officers who had been with the Company for an average of 23 years. AIP
intends to continue the Company's existing business strategy, which includes the
following key elements:
 
          GROW THE AFTERMARKET BUSINESS. The Company has increased its focus on
     the important aftermarket business because of its attractive profit margins
     and its greater stability and predictability compared to the market for new
     equipment. In addition, providing aftermarket support, which is critical to
     maintain machine longevity and productivity in the field, enhances the
     Company's ability to secure new machine orders in the future. The Company's
     focus on its aftermarket business is reflected in a number of recently
     implemented strategic initiatives that include: (i) working with suppliers
     to increase stock levels of replacement parts to shorten response times to
     customer inquiries; (ii) installation of a new computerized parts quoting
     system to improve responsiveness to customer inquiries; (iii) forming a
     dedicated engineering team to focus on reducing manufacturing costs for
     replacement parts; (iv) enhancing relationships with key suppliers in order
     to reduce raw material and purchased part costs; (v) expanding the
     Company's facilities in important foreign markets, such as Chile and South
     Africa; (vi) investing additional capital in the Company's domestic repair
     and service subsidiaries, Boonville Mining Services, Inc. and Minserco,
     Inc.; and (vii) purchasing Von's Welding, Inc., an aftermarket supplier of
     mining machinery parts and services, located in Gillette, Wyoming, in North
     America's most important coal mining region.
 
          The Company has formed relationships with key suppliers of Bucyrus
     products to reduce costs, advance product technology, and improve customer
     support. In addition, the Company is working with suppliers to increase
     their average stock levels of parts in an effort to improve response time
     to customer inquiries. Since 1995, average stock levels have increased from
     approximately $1.0 million to approximately $5.5 million.
 
          Because approximately 64% of the Company's installed equipment base is
     located in international markets, and 76% of the Company's new machine
     sales over the past five years have been to international customers, the
     Company is committed to providing first-rate customer service on a
     worldwide basis. In 1996 and 1997, the Company invested capital in a new
     expanded service center and office complex in Antofagasta, Chile, which
     will primarily service nearby copper mining customers, and an important new
     warehouse facility located in Middleburg, in the heart of the South African
     coal fields.

          Domestically, the Company remains committed to strengthening
     operations at its two wholly-owned subsidiaries, Boonville Mining Services,
     Inc. ("BMSI") and Minserco, Inc. ("Minserco"). BMSI provides replacement
     parts and repair and rebuild services for surface mining equipment
     manufactured both by the Company and by its competitors. Among other
     things, BMSI competes directly with "will-fitters" who sell non-OEM and
     knock off replacement parts, and provides additional manufacturing capacity
     for the Company. Minserco services the mining industry with comprehensive
     structural and mechanical engineering, non-destructive testing, repairs and
     rebuilds of machine components, product and component upgrades, contract
     maintenance, turnkey erections, and machine moves. Minserco's new orders
     have increased from $13.7 million in 1994 to $28.5 million in 1996. In June
     1997, the Company purchased 100% of the stock of Von's Welding, Inc.
     ("Von's") for approximately $2.0 million, including the assumption of
     approximately $1.1 million in liabilities. Von's, located in Gillette,
     Wyoming, is engaged in the business of providing replacement parts and
     aftermarket services for mining equipment and trucks. Von's business will
     be consolidated into Minserco, which will maintain Von's operating facility
     and employees. This acquisition will enhance the Company's presence and
     ability to provide tooling and repair services and replacement parts in
     North America's most important coal mining region.
 
          INCREASE OEM QUALITY AND PROFITABILITY. The Company is committed to
     increasing the profitability of OEM sales by improving the design and
     engineering of its existing line of machines, as well as developing new
     products. During 1996, the Company's engineering and service functions were
     significantly restructured in response to feedback from a customer focus
     group formed to provide direction to the Company's engineering development
     activities. A continuation of this close relationship with customers is
     fundamental to the Company's objective to become more market driven.
     Specific goals included reducing lead times, improving product quality and
     reliability, and improving profit margins and OEM sales. To further these
     goals, the Company has increased its investment in work-in-process
     inventory to reduce delivery times for new equipment orders. The Company's
     commitment to quality has been formally recognized by its receipt of ISO
     9001 Certification from Det Norske Veritas, one of the world's leading
     standards organizations.
 
          MODERNIZE PLANT AND EQUIPMENT. During 1996, the Company began a number
     of initiatives to modernize its manufacturing facilities in order to reduce
     lead times and inventory levels, provide quicker turn around, and reduce
     overall costs of manufacturing both new machines and replacement parts. The
     most significant initiative is a three-year, $20 million modernization
     program at the Company's South Milwaukee facility. The program includes
     replacing approximately 47 older, less efficient machines with 14
     technologically advanced machines, and upgrading 10 existing machine tools.
     Some older machines will be retained by the Company to replace the
     manufacturing capacity of certain Marion machines that will not be
     transferred to the Company's South Milwaukee facility. As of June 30, 1997,
     approximately $5.5 million had been committed to this project and seven of
     the 14 machines had been installed, with the remainder scheduled for
     installation by early 1999. The significant reduction in the number of
     machines will open floor space, allowing the Company to increase capacity
     and to complete the fabrication of Marion's current in-progress inventory
     in South Milwaukee. Following the completion of the modernization program,
     the Company expects to realize significant annual cost savings not
     reflected in the pro forma financial results through the reduction of
     labor, overhead, and raw materials costs.
 
          FOCUS ON STRATEGIC MARKETS. Although 76% of the Company's net sales of
     new machines have come from foreign markets during the past five years
     (primarily Australia, Chile, China, and South Africa), management believes
     that North America (primarily western Canada, the western United States,
     and Mexico) continues to be one of the world's most important markets for
     surface mining equipment. Therefore, the Company's focus includes the
     strategic placement of its new, quality-engineered electric mining shovels
     in high-profile North American
 
                                       54
<PAGE>   61
 
     installations. The Company sold the first of these shovels in Canada in
     1995, and in the United States and Mexico in 1996. The Company believes
     that these installations will create opportunities for increased new
     machine sales in North America. Management has been encouraged by repeat
     orders in 1997 for two additional shovels from one of these customers, and
     the receipt of a shovel order from a new North American customer that has
     historically purchased all its equipment from the Company's primary
     competitor.
 
          EXPAND MARC PROGRAM. The Company is aggressively promoting its
     Maintenance and Repair Contracts, under which mine operators outsource to
     the Company all regular maintenance services, repair functions and, in some
     cases, operation of the equipment serviced. MARCs offer the Company a
     generally predictable, high-margin revenue stream. New mines are the
     primary target for MARCs because it is difficult and expensive for a mining
     company to establish infrastructures for necessary and ongoing maintenance
     and repair in undeveloped or remote areas. The Company currently operates
     eight MARCs and is seeking to expand the MARC program. See "-- Aftermarket
     Parts and Services."
 
     While a number of these initiatives have not been fully implemented and the
anticipated benefits have not yet been fully realized, from 1995 to 1996 the
Company's net sales increased 14%, from $231.9 million to $263.8 million, and
EBITDA (as defined herein) improved from $12.7 million (5.5% of net sales) to
$19.2 million (7.3% of net sales). For the first six months of 1997, as compared
to the first six months of 1996, net sales increased 10%, from $130.8 million to
$143.8 million, and EBITDA (as defined herein) improved from $9.3 million (7.1%
of net sales) to $12.9 million (9.0% of net sales). The Company's consolidated
backlog increased 36% from $158.7 million at December 31, 1996 to $215.8 million
at June 30, 1997. The Marion Acquisition provides the Company with increased
opportunities to implement these initiatives, particularly with respect to
Marion's aftermarket business.
 
INTEGRATION STRATEGIES
 
     Following a detailed review of Marion's business, the Company has developed
a comprehensive plan to integrate Marion's operations into those of the Company.
The Marion Acquisition results in substantial pro forma cost savings, primarily
through the consolidation of Marion's manufacturing operations into the
Company's existing facilities and the rationalization of engineering and
administrative functions. In addition, the Marion Acquisition enhances the
Company's product offering and, through application of the Company's established
business strategies, creates opportunities to capture additional new machine and
aftermarket sales. See "Risk Factors -- Realization of Benefits of the Marion
Acquisition; Integration of Marion" and "Unaudited Pro Forma Combined Condensed
Financial Statements."
 
          CONSOLIDATION OF OPERATIONS. Management expects to realize significant
     cost savings through the integration of Marion's manufacturing operations
     into those of the Company. The Company will relocate some of Marion's
     production machinery and fabricating equipment from the Marion facility to
     the Company's manufacturing operations in South Milwaukee, Wisconsin, and
     Boonville, Indiana. Machinery and tooling that cannot be used in the
     Company's existing facilities will be sold. The estimated annual cost
     savings from the consolidation of manufacturing operations included in the
     pro forma adjustments are approximately $5.0 million. The Company will
     commence the integration of Marion's manufacturing operations as soon as
     possible.
 
          CONSOLIDATION OF SALES, SERVICE, AND ADMINISTRATIVE
     FUNCTIONS. Management expects to realize significant cost savings through
     the rationalization of Marion's and the Company's sales, service, and
     administrative functions. The Company has performed a detailed,
     department-by-department assessment of Marion's existing administrative
     functions and has identified a number of redundant and duplicative
     positions and functions, the elimination of which results in pro forma
     annual cost savings of $6.5 million. The pro forma statements do not
 
                                       55
<PAGE>   62
 
     include any consolidation of sales functions, although it is anticipated
     that numerous positions will be eliminated. In addition, because Marion
     operates administrative and sales offices, parts warehouses, and repair
     facilities in the same geographical areas as the Company, the consolidation
     plan includes closing certain of the former Marion facilities, including
     warehouses and/or repair facilities in Ohio, Wyoming, Alberta, Quebec, and
     South Africa. These cost savings are not reflected in the pro forma
     adjustments. In Australia, the Company plans to close its administrative
     and sales offices and operate out of facilities acquired from Marion.
     Although numerous duplicative positions will be eliminated, certain key
     personnel from Marion's offices, warehouses, and repair facilities will be
     hired and integrated into the Company's administrative, sales, and service
     staff.
 
          CONSOLIDATION OF ENGINEERING FUNCTIONS. The Company hired certain of
     Marion's best-qualified engineers and technicians to assist with the
     integration process and the continued development and production of high
     quality machines. As of December 31, 1996, Marion had already eliminated
     various engineering positions, resulting in the $1.0 million in annual cost
     savings reflected in the pro forma adjustments. The anticipated elimination
     of additional engineering positions is expected to generate additional cost
     savings that are not reflected in the pro forma adjustments. The Company
     currently employs an engineering staff of 70 and believes that this staff,
     in conjunction with the hiring of certain Marion engineers, will provide
     the Company with sufficient engineering support for the foreseeable future;
     however, there can be no assurance that this will be the case.
 
          EXPANSION OF AFTERMARKET BUSINESS. The Marion Acquisition
     significantly increases the Company's aftermarket parts and service
     business, which generated $73.2 million, or approximately 67% of Marion's
     total net sales, during fiscal 1996. By converting Marion's aftermarket
     customers to the Company's service and support programs as soon as
     practicable, the Company seeks not only to maintain existing levels of
     aftermarket sales, but to increase its aftermarket penetration of Marion
     accounts. Although the Company already has relationships with substantially
     all of Marion's customers, to better serve these customers, the Company has
     hired a number of Marion's field personnel, who will continue to be
     responsible for servicing Marion's installed equipment base. The Company
     also believes that the Marion Acquisition creates additional opportunities
     to expand BMSI's and Minserco's operations, helping the Company to become
     more competitive in the aftermarket for parts and services.
 
          INTEGRATION OF PRODUCTS AND TECHNOLOGY. Three of Marion's five
     equipment models and its best technology will be integrated into the
     Company's existing product lines. Marion manufactured two basic models of
     electric mining shovels. The smaller model, which represented six of
     Marion's nine electric mining shovels sold during the past two years and
     has been particularly popular in India, will be incorporated into the
     Company's product line. The larger model is similar to the Company's most
     popular electric shovel model and will therefore be discontinued. Two of
     Marion's smaller special purpose dragline models will be incorporated into
     the Company's product line to complement the larger models currently
     offered by the Company.
 
          COSTS AND EXPENSES ASSOCIATED WITH THE MARION ACQUISITION. The Company
     expects to incur one-time costs and expenses of approximately $6.2 million
     in connection with the Marion Acquisition and the integration of Marion's
     business into the Company's operations. These costs primarily relate to
     moving certain equipment from Marion, Ohio, to the Company's existing
     facilities, relocating personnel, and consolidating offices and warehouses.
     Under the terms of the purchase agreement, Global retained ownership of
     Marion's manufacturing facility in Marion, Ohio, and is responsible for all
     severance costs, pension expenses, and postretirement medical and other
     benefits associated with the closing of Marion's manufacturing operations.
     The Company's existing facilities and equipment are anticipated to be
     adequate to fulfill expected sales with little need for additional capital
     expenditures other than previously planned modernization of specific
     equipment; however, there can be no assurance that this will be the case.

INDUSTRY OVERVIEW
 
     The large-scale surface mining equipment manufactured and serviced by the
Company is used primarily in coal, copper, and iron ore mines worldwide. Growth
in demand for these commodities is a function of population growth and
continuing improvements in standards of living in many areas of the world. The
market for new surface mining equipment is somewhat cyclical in nature due to
market fluctuations for these commodities; however, the aftermarket for parts
and services is more stable because these expensive, complex machines are
typically kept in continuous operation for 15 to 30 years and require regular
maintenance and repair throughout their productive lives.
 
     Although total industry sales of new equipment have varied substantially
from year to year, management estimates that since 1987 total worldwide sales of
rotary blast hole drills, electric mining shovels and draglines have averaged
approximately $285 million annually. The largest markets for this mining
equipment have been in Australia, Canada, China, India, Russia, South Africa,
South America, and the United States. Together, these markets typically account
for approximately 90% of all new machines sold, although in any given year,
markets in other countries may assume greater importance. See "Risk Factors --
Cyclical Nature of Industry; Potential Fluctuations in Operating Results," and
"-- Competition."
 
MARKETS SERVED
 
     While the Company's products are used in a variety of different types of
mining operations, including gold, phosphate, bauxite, and oil sands, as well as
for land reclamation, the Company manufactures surface mining equipment
primarily for large companies and quasi-governmental entities engaged in the
mining of coal, iron ore, and copper throughout the world. Until the late 1980s,
coal mining accounted for the largest percentage of industry demand for the
Company's machines, and it continues to be one of the largest users of
replacement parts and services. In recent years, however, copper and iron ore
mining operations have accounted for an increasingly greater share of new
machine sales. During the past five years, approximately 55% of the Company's
new equipment orders have gone to customers who mine copper, 32% to iron ore
mining customers, and 13% to coal mining customers. Nevertheless, while the
copper and iron ore mining industries have accounted for the majority of new
machine sales in recent years, the increasing worldwide demand for coal is
expected to continue and the Company expects that coal mining will account for
an increasing percentage of new machine sales over the next several years.
 
          COPPER. From 1995 to 1996, copper consumption increased by 2.5% in the
     United States, with European countries such as France, Germany, Italy and
     Britain experiencing similar growth. This growth in demand is attributable
     to both general economic growth, as well as increased use of copper in
     high-tech industrial production. Unusual trading activity led to a sharp
     decline in copper prices in mid-1996 from historically high levels; since
     then, copper prices have recovered, and as a result, several new copper
     projects have been put back on line and existing mines expanded in
     Argentina, Chile, Indonesia, Mexico, and Sweden. These initiatives have
     resulted in increased demand for the Company's excavation equipment in
     these markets. In spite of the fluctuations during 1996, copper prices are
     expected to remain relatively firm through 1997. According to Metal
     Bulletin Research, an industry periodical, copper consumption is expected
     to grow at approximately 2.3% in 1997.
 
          IRON ORE. Although iron ore demand decreased with the worldwide
     recession of 1992 and 1993, and Japanese and European iron ore buyers
     lowered ore contract prices significantly in 1992 and again in 1993, there
     was an increase in iron ore production in late 1994 that was sustained
     through 1995 when global consumption increased, creating additional demand
     for steel. In 1995, iron ore was the most widely traded non-energy
     commodity in both value and volume, and the iron ore market passed the one
     billion tons level, setting a new record for the worldwide industry. Prices
     for iron ore began to recover slightly in 1995 and 1996, climbing back
 
                                       57
<PAGE>   64
 
     to 1992 levels. AME Mineral Economic analysts predict that iron ore
     production will rise 10% by the year 2000.
 
          COAL. The demand for steam coal, which represents approximately 85% of
     total coal mining activity, is based largely on the demand for electric
     power and the price and availability of competing sources of energy, such
     as oil, natural gas, and nuclear power. Initially, the 1973 Arab oil
     embargo resulted in an unprecedented increase in the demand for coal
     production, reflecting expectations that oil prices would continue to rise.
     Eventually the effects of a worldwide recession, escalating interest rates,
     energy conservation efforts, and an increase in the world's supply of oil
     resulted in a sharp drop in demand for coal. More recently, coal production
     in the United States has been impacted by the Clean Air Act, causing higher
     sulfur coal mines to be closed or to have outputs drastically curtailed.
     Many machines have been shut down and a few have been relocated to lower
     sulfur mines in eastern Appalachia and Wyoming's Powder River Basin where
     excess production capacity and stagnant demand have driven coal prices
     downward. Nevertheless, the increase in demand for coal in developing
     countries with rapidly growing populations, such as India and China, has
     stimulated coal mining production worldwide and is eventually expected to
     increase both domestic and foreign demand for excavation equipment. The
     Energy Information Administration is forecasting an increase in world
     energy demand and an increase in world coal consumption.
 
     The Company's excavation machines are used for land reclamation as well as
for mining, which has a positive effect on the demand for its products and
replacement parts and expands the Company's potential customer base. Current
federal and state legislation regulating surface mining and reclamation may
affect some of the Company's customers, principally with respect to the cost of
complying with, and delays resulting from, reclamation and environmental
requirements.
 
OEM PRODUCTS
 
     The Company's line of original equipment manufactured ("OEM") products
includes a full range of rotary blast hole drills, electric mining shovels, and
draglines.
 
          ROTARY BLAST HOLE DRILLS. Most surface mines require breakage or
     blasting of rock, overburden, or ore by explosives. To accomplish this, it
     is necessary to bore out a pattern of holes into which the explosives are
     placed. Rotary blast hole drills are used to drill these holes, and are
     usually described in terms of the diameter of the hole they bore. The
     average life of a blast hole drill is 15 to 20 years.
 
          The Company manufactures the world's top selling rotary blast hole
     drills, having produced a majority of the estimated 69 drills sold in the
     industry during 1995 and 1996. The Company offers a line of rotary blast
     hole drills ranging in hole diameter size from 9.0 inches to 17.5 inches
     and ranging in price from approximately $1.5 million to $2.8 million per
     drill, depending on machine size and variable features.
 
          In an effort to enhance drill sales and expand its market position,
     during 1996 the Company introduced the Model 39R diesel hydraulic blast
     hole drill, the Company's third drill model and first diesel hydraulic
     blast hole drill. This innovative machine breaks new ground in
     maneuverability and the ability to drill in difficult terrain, as well as
     offering extraordinary drill productivity and functions unavailable in
     other manufacturers' models.
 
          ELECTRIC MINING SHOVELS. Mining shovels are primarily used to load
     coal, copper ore, iron ore, other mineral-bearing materials, overburden, or
     rock into trucks. There are two basic types of mining shovels, electric and
     hydraulic. Electric mining shovels are able to handle larger shovels or
     "dippers," allowing them to load greater volumes of rock and minerals,
     while hydraulic shovels are smaller and more maneuverable. The Company
     manufactures only electric mining shovels. The average life of an electric
     mining shovel is 15 to 20 years.
 
                                       58
<PAGE>   65
 
          Shovels are characterized in terms of weight and dipper capacity. The
     Company offers a full line of electric mining shovels, weighing from 400 to
     1,000 tons and having dipper capacities from 12 to 80 cubic yards. Prices
     range from approximately $3 million to approximately $9 million per shovel.
     The Company's most popular electric mining shovel model is the Model 495B,
     which is known for its reliability and productivity.
 
          The Company's electric mining shovels continue to be extremely popular
     in the surface mining industry. In the developing coal mining market of
     China and in the rapidly growing Chilean copper mining market, Bucyrus
     shovels have accounted for the majority of new electric mining shovels
     purchased since 1988. Among the Company's business strategies is the
     strategic placement of new electric mining shovels in high-profile North
     American mining installations.
 
          DRAGLINES. Draglines are primarily used to remove overburden, which is
     the earth located over a coal or mineral deposit, by dragging a large
     bucket through the overburden, carrying it away and depositing it in a
     remote spoil pile. The Company's draglines weigh from 500 to 7,500 tons,
     and are typically described in terms of their "bucket size," which can
     range from nine to 220 cubic yards. The Company currently offers a full
     line of models ranging in price from $10 million to over $60 million per
     dragline. The average life of a dragline is 20 to 30 years.
 
          Draglines are the industry's largest and most expensive type of
     equipment, and while sales are sporadic, each dragline represents a
     significant sales opportunity. Management therefore remains committed to
     maintaining the Company's ability to produce these machines. In September
     1997, the Company signed an agreement with an Australian mining company to
     build the world's fourth largest dragline, which is scheduled for
     completion by December 31, 1999. This is expected to generate net sales of
     approximately $57.5 million over the next two and a half years.
 
AFTERMARKET PARTS AND SERVICES
 
     The Company has a comprehensive aftermarket business that supplies
replacement parts and services for the surface mining industry. Although the
vast majority of the Company's sales of aftermarket parts and services has been
in support of the large installed equipment base of over 900 Bucyrus machines
worldwide, the Company also manufactures parts and provides services for other
manufacturers' installed equipment. The Company's aftermarket services include
maintenance and repair labor, technical advice, refurbishment, and relocation of
older, installed machines, particularly draglines. The Company also provides
engineering, manufacturing, and servicing for the consumable rigging products
that attach to dragline buckets (such as dragline teeth and adapters, shrouds,
dump blocks, and chains) and shovel dippers (such as dipper teeth, adapters, and
heel bands).
 
     During 1996, the Company generated $156.4 million (59% of total net sales)
from its aftermarket business. In general, the Company realizes higher margins
on sales of parts and services than it does on sales of new machines. Moreover,
because the expected life of large, complex mining machines ranges from 15 to 30
years, the Company's aftermarket business is inherently more stable and
predictable than the fluctuating market for new products. Over the life of a
machine, net sales generated from aftermarket parts and services can exceed the
original purchase price.
 
     Approximately 70% of the Company's aftermarket business relates to
providing parts and services to newer mining equipment operating in
international markets, while the remaining 30% of the aftermarket business
caters to equipment located in the United States, which is generally older. A
substantial portion of the Company's international repair and maintenance
services are provided through its global network of wholly-owned foreign
subsidiaries and overseas offices, operating in Australia, Brazil, Canada,
Chile, China, England, India, Mauritius, and South Africa. The Company's two
domestic subsidiaries, Minserco and BMSI, provide repair and maintenance
services
 
                                       59
<PAGE>   66
 
throughout North America. Minserco, which maintains offices in Florida, Texas,
West Virginia, and Wyoming, provides comprehensive structural and mechanical
engineering, non-destructive testing, repairs and rebuilds of machine
components, product and component upgrades, contract maintenance, turnkey
erections, and machine moves. Minserco's services are provided almost
exclusively to maintenance and repair of Bucyrus machines operating in North
America. BMSI, located in Boonville, Indiana, builds replacement parts and
provides repair and rebuild services both for Bucyrus machines and other
manufacturers' equipment. The majority of BMSI's business is located in North
America.
 
     To comply with the increasing aftermarket demands of larger mining
customers, the Company offers comprehensive maintenance and repair contracts.
Under these contracts, the Company provides all replacement parts, regular
maintenance services, and necessary repairs for the excavation equipment at a
particular mine with an on-site support team. In addition, two of these
contracts call for Company personnel to operate the equipment serviced. MARCs
are highly beneficial to the Company's mining customers because they promote
high levels of equipment reliability and performance, allowing the customer to
concentrate on mining production. MARCs typically have terms of three to five
years with standard termination and renewal provisions, although some contracts
allow termination by the customer for any cause. In recent years, the Company
has aggressively promoted its MARC program because it provides the Company with
a predictable, high margin form of business. New mines in areas such as Chile
and Argentina are the primary targets for MARCs because it is difficult and
expensive for mining companies to establish the necessary infrastructures for
ongoing maintenance and repair in underdeveloped or remote locations. The
Company currently operates eight MARCs and has plans to expand this program.
 
CUSTOMERS
 
     The Company does not consider itself dependent upon any single customer or
group of customers; however, on an annual basis a single customer may account
for a large percentage of sales, particularly new machine sales. For example,
during fiscal 1996, sales to Compania Minera Dona Ines de Collahuasi, S.A., a
Chilean copper mining company, accounted for approximately 14% of the Company's
net sales. In fiscal 1994 and 1995, BHP Coal Pty. Ltd., an Australian mining
company, accounted for approximately 20% and 22%, respectively, of the Company's
net sales, and approximately 26% and 17%, respectively, of Marion's net sales.
See "Risk Factors -- Cyclical Nature of Industry; Potential Fluctuations in
Operating Results."
 
MARKETING, DISTRIBUTION AND SALES
 
     In the United States, new mining machinery is primarily sold directly by
Company personnel, and to a lesser extent, through a northern Minnesota
distributor who supplies customers in the iron ore mining regions of the Upper
Midwest. Outside of the United States, new equipment is sold by Company
personnel, through independent distributors and through the Company's
subsidiaries and offices located in Australia, Brazil, Canada, Chile, China,
England, India, Mauritius, and South Africa. Aftermarket parts and services are
primarily sold directly through the Company's foreign subsidiaries and offices
and through the Company's domestic subsidiaries, Minserco and BMSI. The Company
believes that marketing through its own global network of subsidiaries and
offices offers better customer service and support by providing customers with
direct access to the Company's technological and engineering expertise.
 
     With the exception of the MARC business, all the Company's sales are on a
project-by-project basis. Typical payment terms for new equipment require a down
payment, and invoicing is done on a percent of completion basis, such that a
substantial portion of the purchase price is received by the time shipment is
made to the customer. Sales contracts for machines are predominantly at fixed
prices, with escalation clauses in certain cases. Most sales of replacement
parts call for prices in effect at the time of order. During 1996, price
increases from inflation had a relatively minor impact on the Company's reported
net sales.
 
                                       60
<PAGE>   67
 
FOREIGN OPERATIONS
 
     A substantial portion of the Company's net sales and operating earnings is
attributable to operations located abroad. Over the past five years, 76% of the
Company's new machine sales have been in international markets. The Company's
foreign sales, consisting of exports from the United States and sales by
consolidated foreign subsidiaries, totaled $191.9 million in 1996, $169.1
million in 1995, and $131.8 million in 1994.
 
     The Company's largest foreign markets are in Australia, Chile, China, and
South Africa. The Company also employs direct marketing strategies in developing
markets, such as Brazil, India, Indonesia, Jordan, Morocco, and Russia. In
recent years, Australia and South Africa have emerged as strong producers of
metallurgical coal, while Chile and South Africa have continued to be leading
producers of other minerals, primarily copper and gold, respectively. The
Company expects that India and Russia will become major coal producing regions
in the future. In India, the world's second most populous country, the demand
for coal as a major source of energy is expected to increase over the next
several decades.
 
     New machine sales in foreign markets are supported by the Company's
established network of foreign subsidiaries and overseas offices that directly
market the Company's products and provide ongoing services and replacement parts
for equipment installed abroad. The availability and convenience of the services
provided through this worldwide network not only promotes high margin
aftermarket sales of parts and services, but also gives the Company an advantage
in securing new machine orders.
 
     Bucyrus and its U.S. subsidiaries normally price their products, including
direct sales of new equipment to foreign customers, in U.S. dollars. Foreign
subsidiaries normally procure and price aftermarket replacement parts and repair
services in the local currency. Approximately 70% of the Company's net sales are
priced in U.S. dollars. The value, in U.S. dollars, of the Company's investments
in its foreign subsidiaries and of dividends paid to the Company by those
subsidiaries will be affected by changes in exchange rates. The Company does not
normally enter into currency hedges, although it may do so with regard to
certain individual contracts. See "Risk Factors -- Foreign Operations."
 
COMPETITION
 
     There are a limited number of manufacturers of new surface mining
equipment. The Company is one of two manufacturers of electric mining shovels
and draglines. The Company's only competitor in electric mining shovels and
draglines is Harnischfeger Corporation, although electric mining shovels also
compete against hydraulic shovels of which there are at least six other
manufacturers. In rotary blast hole drills, the Company competes with at least
three other manufacturers, including Harnischfeger Corporation. Methods of
competition are diverse and include product design and performance, service,
delivery, application engineering, pricing, financing terms, and other
commercial factors. See "Risk Factors -- Competition."
 
     For most owners of the Company's machines, the Company is the primary
replacement source for large, heavily engineered, integral components; however,
the Company encounters intense competition for sales of smaller, less
sophisticated, consumable replacement parts and repair services in certain
markets. The Company's competition in parts sales consists primarily of smaller,
independent firms called "will-fitters," that produce copies of the parts
manufactured by the Company and other original equipment manufacturers. These
copies are generally sold at lower prices than genuine parts produced by the
manufacturer. Management estimates that there are over 90 will-fitters competing
with the Company in the aftermarket business, almost exclusively in North
America, and that they accounted for an estimated 75% of North American sales in
the aftermarket parts and service business in 1996. Outside North America,
customers mainly rely upon the Company's subsidiaries to provide aftermarket
parts and services.
 
                                       61
<PAGE>   68
 
     The Company has a variety of programs to attract large volume customers for
its replacement parts. Although will-fitters engage in significant price
competition in parts sales, the Company possesses clear non-price advantages
over will-fitters. The Company's engineering and manufacturing technology and
marketing expertise exceed that of its will-fit competitors, who are in many
cases unable to duplicate the exact specifications of genuine Bucyrus parts.
Moreover, use of parts not manufactured by the Company can void the warranty on
a new Bucyrus machine, which generally runs for one year on new equipment, with
certain components being warranted for longer periods.
 
RAW MATERIALS AND SUPPLIES
 
     The Company purchases from outside vendors the semi- and fully-processed
materials (principally structural steel, castings, and forgings) required for
its manufacturing operations, and other items, such as electrical equipment,
that are incorporated directly into the end product. The Company's foreign
subsidiaries purchase components and manufacturing services both from local
subcontractors and from Bucyrus. Certain additional components are sometimes
purchased from subcontractors, either to expedite delivery schedules in times of
high demand or to reduce costs. Moreover, in countries where local content
preferences or requirements exist, local subcontractors are used to manufacture
a substantial portion of the components required in the Company's foreign
manufacturing operations. Although the Company is not dependent upon any single
supplier, there can be no assurance that the Company will continue to have an
adequate supply of raw materials or components necessary to enable it to meet
the demand for its products. Competitors are believed to be subject to similar
conditions.
 
MANUFACTURING
 
     A substantial portion of the design, engineering, and manufacturing of
Bucyrus machines is done at the Company's South Milwaukee plant. The size and
weight of these mining machines dictates that the machines be shipped to the job
site in sub-assembled units where they are assembled for operation with the
assistance of Company technicians. Planning and on-site coordination of machine
assembly is a critical component of the Company's service to its customers.
Moreover, to reduce lead time and assure that customer delivery requirements are
met, the Company maintains an inventory of sub-assembled units for frequently
utilized components of various types of equipment.
 
     The Company manufactures and sells replacement parts and components and
provides comprehensive aftermarket service for its entire line of mining
machinery. The Company's large installed base of surface mining machinery
provides a steady stream of parts sales due to the long useful life of the
Company's machines, averaging 20 to 30 years for draglines and 15 to 20 years
for electric mining shovels and blast hole drills. Parts sales and aftermarket
services comprise a substantial portion of the Company's net sales. The Company
also provides aftermarket service for certain equipment of other original
equipment manufacturers through BMSI.
 
     Although a majority of the Company's operating profits are derived from
sales of parts and services, the long-term prospects of the Company depend upon
maintaining a large installed equipment base worldwide. Therefore, the Company
remains committed to improving the design and engineering of its existing line
of machines, as well as developing new products. In 1996, a three year machine
shop modernization program began in the Company's South Milwaukee manufacturing
facility that involves a $20 million investment in the latest technology in the
machine tool industry. The program is aimed at reduced lead times, quicker
turnaround, reduced in-process inventory, and overall cost reduction. See "--
Business Strategy -- Plant and Equipment Modernization."

PROPERTIES
 
     The Company's principal manufacturing plant in the United States is located
in South Milwaukee, Wisconsin, and is owned by the Company. This plant comprises
approximately 1,038,000 square feet of floor space. A portion of this facility
houses the Company's corporate offices. The major buildings at this facility are
constructed principally of structural steel, concrete, and brick and have
sprinkler systems and other devices for protection against fire. The buildings
and equipment therein, which include machine tools and equipment for fabrication
and assembly of the Company's mining machinery, including draglines, electric
mining shovels, and blast hole drills, are well-maintained, in good condition,
and in regular use.
 
     The Company leases a facility in Memphis, Tennessee, which has
approximately 110,000 square feet of floor space and is used as a central parts
warehouse. The current lease is for five years commencing in July 1996 and
contains an option to renew for an additional five years.
 
     BMSI leases a facility in Boonville, Indiana which has approximately 60,000
square feet of floor space on a 5.84 acre parcel of land. The facility has the
manufacturing capability of large machining, gear cutting, heavy fabricating,
rebuilding, and stress relieving. The major manufacturing buildings are
constructed principally of structural steel with metal siding.
 
     The Company also has administrative and sales offices and, in some
instances, repair facilities and parts warehouses, at certain of its foreign
locations, including Australia, Brazil, Canada, Chile, China, India, and South
Africa. The Company plans to do business out of Marion's offices in Australia,
and close down the Company's existing leased offices there.
 
EMPLOYEES
 
     As of July 31, 1997, the Company had approximately 1,413 full-time
employees, approximately 892 of whom were working primarily in the United
States. In addition, from time to time the Company employs part-time employees
to handle peak loads. Of the 797 employees at the Company's South Milwaukee
facility, 418 are represented by the United Steelworkers of America. In May
1997, the union ratified a new four year agreement with the Company that expires
on April 30, 2001. See "Risk Factors -- Labor Relations."
 
LEGAL PROCEEDINGS
 
     JOINT PROSECUTION. The Company and its former affiliate Jackson National
Life Insurance Company ("JNL") entered into a joint prosecution agreement (the
"Joint Prosecution Agreement") dated as of August 21, 1997 relating to various
claims the Company and JNL have or may have resulting from the Company's
reorganization in 1994 under Chapter 11 of the United States Bankruptcy Code
(the "Chapter 11 Reorganization") against the law firm of Milbank, Tweed, Hadley
& McCloy ("Milbank") for disgorgement of fees (the "Disgorgement Claim") and
other claims (collectively, the "Milbank Claims"). All proceeds of the Milbank
Claims will be allocated as follows: (i) first, to pay, or to reimburse the
prior payment of, all bona fide third-party costs, expenses and liabilities
incurred on or after September 1, 1997 in connection with prosecuting the
Milbank Claims (the "Joint Prosecution") including, without limitation, the
reasonable fees and disbursements of counsel and other professional advisors,
which are to be advanced by JNL; (ii) the next $8.675 million of proceeds from
the Milbank Claims, if any, will be paid to JNL, provided that the Company will
retain 10% of the proceeds of the Disgorgement Claim, if any, and will direct
payment to JNL of the balance of such proceeds; and (iii) all additional
proceeds of the Milbank Claims will be divided equally between JNL and the
Company. Notwithstanding the foregoing, the Company shall also receive the
benefit of any reduction of any obligation it may have to pay Milbank's
outstanding fees if any. JNL will indemnify the Company in respect of any
liability resulting from the Joint Prosecution other than in respect of legal
fees and expenses incurred prior to September 1, 1997. The Joint Prosecution may
involve lengthy and complex litigation and there can be no assurance whether or
when any recovery may be obtained or, if obtained, whether it will be in
 
                                       63
<PAGE>   70
 
an amount sufficient to result in the Company receiving any portion thereof
under the formula described above.
 
     Consistent with the Joint Prosecution Agreement, on September 25, 1997, the
Company and JNL commenced an action against Milbank (the "Milwaukee Action") in
the Milwaukee County Circuit Court. The Company seeks damages against Milbank
arising out of Milbank's alleged malpractice, breach of fiduciary duty, common
law fraud, breach of contract, unjust enrichment and breach of the obligation of
good faith and fair dealing. JNL seeks damages against Milbank arising out of
Milbank's alleged tortious interference with contractual relations, abuse of
process and common law fraud. The Company and JNL seek to recover actual and
punitive damages from Milbank. On October 1, 1997, Milbank removed the Milwaukee
Action to the United States District Court for the Eastern District of
Wisconsin. On October 7, 1997, the Company and JNL moved to remand the
proceeding to the Milwaukee County Circuit Court. Milbank's response to the
motion to remand is due by November 4, 1997, and Milbank's response to the
complaint in the Milwaukee Action is due by December 1, 1997. The Milwaukee
Action may involve lengthy and complex litigation and there can be no assurance
whether or when any recovery may be obtained or, if obtained, whether it will be
in an amount sufficient to result in the Company receiving any portion thereof
under the formula described above.
 
     On September 23, 1997, Minserco, Inc, one of the Guarantors, was found
liable to BR West Enterprises, Inc. d/b/a West Machine and Tool Works ("West")
in litigation pending in the United States District Court for the Eastern
District of Texas (the "Texas Court"), for damages claimed with regard to an
alleged joint venture agreement. On October 29, 1997, a final judgment was
entered in the amount of $4.3 million, including attorney's fees and costs.
Minserco strongly disputes the Findings of Fact and Conclusions of Law entered
by the Texas Court and intends to seek a new trial and, if not successful to
vigorously appeal the case to the United States Court of Appeals for the Fifth
Circuit. It is the view of management that Minserco's ultimate liability, if
any, in this action is not expected to have a material effect on the Company's
financial position or results of operations, although no assurance to that
effect can be given.
 
     The Company is normally subject to numerous product liability claims, many
of which relate to products no longer manufactured by Bucyrus or its
subsidiaries, and other claims arising in the ordinary course of business. The
Company has insurance covering most of said claims, subject to varying
deductibles ranging from $0.3 million to $3.0 million, and has various limits of
liability depending on the insurance policy year in question. It is the view of
management that the final resolution of said claims and other similar claims
which are likely to arise in the future will not individually or in the
aggregate have a material effect on the Company's financial position or results
of operations, although no assurance to that effect can be given.
 
     The Company is involved in various other litigation arising in the normal
course of business. It is the view of management that the Company's recovery or
liability, if any, under pending litigation is not expected to have a material
effect on the Company's financial position or results of operations, although no
assurance to that effect can be given.
 
ENVIRONMENTAL AND RELATED MATTERS
 
     The Company's operations and properties are subject to a broad range of
federal, state, local and foreign laws and regulations relating to environmental
matters, including laws and regulations governing discharges into the air and
water, the handling and disposal of solid and hazardous substances and wastes,
and the remediation of contamination associated with releases of hazardous
substances at Company facilities and at off-site disposal locations. These laws
are complex, change frequently and have tended to become more stringent over
time. Future events, such as compliance with more stringent laws or regulations,
or more vigorous enforcement policies of regulatory agencies or stricter or
different interpretations of existing laws, could require additional
 
                                       64
<PAGE>   71
 
expenditures by the Company, which may be material. See "Risk Factors --
Environmental and Related Matters."
 
     Certain environmental laws, such as CERCLA, provide for strict, joint and
several liability for investigation and remediation of spills and other releases
of hazardous substances. Such laws may apply to conditions at properties
presently or formerly owned or operated by an entity or its predecessors, as
well as to conditions at properties at which wastes or other contamination
attributable to an entity or its predecessors come to be located.
 
     The Company was one of 53 entities named by the U.S. Environmental
Protection Agency ("EPA") as potentially responsible parties ("PRPs") with
regard to the Millcreek dumpsite, located in Erie County, Pennsylvania, which is
on the National Priorities List of sites for cleanup under CERCLA. The Company
was named as a result of allegations that it disposed of foundry sand at the
site in the 1970's. Both the United States government and the Commonwealth of
Pennsylvania initiated actions to recover cleanup costs; the Company has settled
with both with respect to its liability for past costs. In addition 37 PRPs,
including the Company, have received Administrative Orders issued by the EPA
pursuant to Section 106(a) of CERCLA to perform site capping and flood control
remediation at the Millcreek site. The Company is one of 18 parties responsible
for a share of the estimated $7.0 million in costs, which share is presently
proposed as per capita but may be subject to reallocation before the conclusion
of the case.
 
     In December 1990, the Wisconsin Department of Natural Resources ("DNR")
conducted a pre-remedial screening site inspection on property owned by the
Company located at 1100 Milwaukee Avenue, in South Milwaukee, Wisconsin.
Approximately 35 acres of this site were allegedly used as a landfill by the
Company until approximately 1983. The Company disposed of certain manufacturing
wastes at the site, primarily foundry sand. DNR's Final Site Screening Report,
dated April 16, 1993, summarized the results of additional investigation. A DNR
Decision Memo, dated July 21, 1991, which was based upon the testing results
contained in the Final Site Screening Report, recommended additional
groundwater, surface water, sediment and soil sampling. To date, the Company is
not aware of any initiative by the DNR to require any further action with
respect to this site. Consequently, the Company has not regarded and does not
regard, this site as presenting a material contingent liability. There can be no
assurance, however, that additional investigation by the DNR will not be
conducted with respect to this site at some later date or that this site will
not in the future require removal or remedial actions to be performed by the
Company, the costs of which could, depending on the circumstances, be material.
 
     Prior to 1985, a wholly owned indirect subsidiary of Bucyrus provided
comprehensive general liability insurance coverage for affiliate corporations.
The subsidiary issued such policies for occurrences during the years 1974 to
1984, which policies could involve material liability. Claims have been made
under certain of these policies for certain potential CERCLA liabilities of
former Bucyrus subsidiaries. It is possible that other claims could be asserted
in the future with respect to such policies. While the Company does not believe
that liability under such policies will result in material costs, this cannot be
guaranteed.
 
     Along with multiple other parties, the Company or its subsidiaries are
currently PRPs under CERCLA and analogous state laws at three additional sites
at which Bucyrus and/or its subsidiaries (including the above referenced
insurance subsidiary by insurance claim) may incur future costs. While CERCLA
imposes joint and several liability on responsible parties, liability for each
site is likely to be apportioned among the parties. The Company does not believe
that its potential liability in connection with these sites or any other
discussed above, either individually or in the aggregate, will have a material
adverse effect on the Company's business, financial condition or results of
operations. However, the Company cannot guarantee that it will not incur cleanup
liability in the future with respect to sites formerly or presently owned or
operated by the Company, or with respect to off-site locations, the costs of
which could be material.
 
                                       65
<PAGE>   72
 
     The Company has also been named as a defendant in seven pending premises
liability asbestos cases, which are proceeding both in the state courts of
Indiana and federal court. In all these cases, insurance carriers have accepted
the defense of such cases. These cases are in preliminary stages and while the
Company does not believe that costs associated with these matters will be
material, it cannot guarantee that this will be the case.
 
     While no assurance can be given, the Company believes that expenditures for
compliance and remediation will not have a material effect on its capital
expenditures, earnings or competitive position.
 
PATENTS, LICENSES AND FRANCHISES
 
     The Company has a number of United States and foreign patents, patent
applications and patent licensing agreements. It does not consider its business
to be materially dependent upon any patent, patent application, or patent
license agreement.
 
CHAPTER 11 REORGANIZATION
 
     On February 4, 1988, the Company was acquired in a leveraged buyout by
former members of management and a group of investors led by Goldman, Sachs &
Co. and Broad Street Investment Fund (the "LBO"). The Company was acquired for
approximately $300 million of which only $2.0 million was equity.
 
     Although the Company's strong aftermarket parts business covered most of
its cash flow requirements, it was insufficient to service the LBO debt and
simultaneously provide the working capital necessary to build new machines.
Moreover, the Company's former management employed a strategy of selling new
machines below cost in order to maintain market share and to compensate its
customers for the long lead times that resulted from the lack of sufficient
working capital to stock the components required to match the lead times of its
competitors.
 
     While the Company experienced increasing net sales from 1988 to 1991, the
Company continued to increase its use of leverage. Additionally, in 1990 the
Company settled tax disputes for the years 1977 to 1982 that required an
additional $22 million of borrowings. Subsequently, in January 1993, in the
midst of a cyclical downturn in the mining industry, the Company's interest
expense obligations increased dramatically as the interest rates on several
issues of the Company's debt obligations reset resulting in the majority of the
Company's debt obligations accruing interest at effective rates ranging from 15%
to in excess of 20%. The Company subsequently announced its intention not to pay
interest on a large majority of its debt obligations, and in February 1994, the
Company filed a prepackaged plan of reorganization under Chapter 11 of the U.S.
Bankruptcy Code. In December 1994, the Company's plan of reorganization was
confirmed.

(4)  Mr. Miller became Interim President and Chief Executive Officer pursuant to
     a Management Agreement (the "Management Agreement"), dated July 21, 1995, 
     as amended, between the Company and Miller Associates. Amounts paid by the
     Company under the Management Agreement were paid to Miller Associates and
     Mr. Miller was separately compensated by Miller Associates. Pursuant to the
     Management Agreement, Mr. Miller served as Interim President and Chief
     Executive Officer until March 11, 1996 when Mr. Hildebrand was appointed as
     President and Chief Executive Officer by the Board.
 
     EMPLOYMENT AGREEMENTS; CHANGE OF CONTROL
 
     The Company has entered into employment agreements with all of the named
executive officers. These agreements govern the compensation, benefits and
treatment upon termination under various circumstances, including voluntary
termination by either party, or termination by reason of retirement, death or
disability, or in the event of a change of control, as those terms are defined
in the agreements. Each employment agreement automatically renews for a one year
term upon the expiration of its initial term and any subsequent terms, unless
two months' written notice is given by either party of intent to terminate at
the end of that term. Each employment agreement may be terminated by either the
Company or the executive at any time by giving notice as required under the
agreement; provided, however, that if the named executive officer is terminated
by the Company without cause at any time, or if the executive terminates his
employment with good reason in connection with a change in control, as those
terms are defined in the agreement, then the executive will be entitled to
certain severance benefits as described in that executive's individual
agreement. Finally, each agreement imposes confidentiality restrictions on the
executive and places restrictions on the executive's involvement in activities
that may compete with the Company both during employment and following
termination. Violation of such confidentiality and non-competition provisions,
or other termination for cause, as defined in the agreements, may result in
forfeiture of severance and other benefits that may otherwise accrue. Individual
compensation, benefits and other salient features of each agreement is described
below.
 
     Mr. Hildebrand serves as President and Chief Executive Officer under a
three-year employment agreement with the Company, dated March 11, 1996. Mr.
Hildebrand's base salary is $400,000 per year, subject to increase at the
discretion of the Board, and he is eligible to participate in the Company's
Management Incentive Plan ("Bonus Plan"), which, in Mr. Hildebrand's case,
provides for an annual cash incentive bonus equal to 50% of base salary in the
event of achievement of targeted performance and a maximum of 100% of base
salary in the event of exceptional performance, as determined in accordance with
the Bonus Plan. In addition, Mr. Hildebrand was granted 300,000 shares of
restricted stock and options for 200,000 shares of Common Stock at 55% of its
grant date market price, all of which were tendered and purchased (in the case
of restricted stock) or cancelled and redeemed (in the case of stock options) in
connection with the AIP Merger. Mr. Hildebrand is entitled to participate in the
Company's employee benefit plan for senior executives and provided other fringe
benefits, such as club membership, vacation and the use of a Company car.
Finally, Mr. Hildebrand's employment agreement provided for one time payments to
compensate him for lost retirement benefits and to reimburse him for costs
associated with the relocation of his residence.
 
     Mr. Smoke serves as Chief Financial Officer under a one-year employment
agreement with the Company, dated November 7, 1996. Mr. Smoke's base salary is
$175,000 per year, subject to increase at the discretion of the Board, and he is
eligible to participate in the Bonus Plan, which, in Mr. Smoke's case, provides
for an annual cash incentive bonus equal to 35% of base salary in the event of
achievement of targeted performance and a maximum of 70% of base salary in the
event of exceptional performance, as determined in accordance with the Bonus
Plan. In addition, Mr. Smoke was granted options for 30,000 shares of Common
Stock, as well as stock appreciation rights to
 
                                       70
<PAGE>   77
 
50,000 shares, all of which were cancelled and redeemed in connection with the
AIP Merger. Mr. Smoke is entitled to participate in the Company's employee
benefit plan for senior executives and provided other fringe benefits, such as
club membership, vacation and the use of a Company car. Finally, Mr. Smoke's
employment agreement provides for one time payments to reimburse him for costs
associated with the relocation of his residence.
 
     Mr. Sullivan, Mr. Mackus, Mr. Phillips, and Mr. Onsager each serve under
similar one-year employment agreements with the Company dated May 21, 1997. Each
of these agreements provides for the executive's position and base salary, which
is subject to merit increases in accordance with the Company's normal salary
merit increase review policy. In addition, the executive is entitled to
participate in such employee and fringe benefits plans as the Company provides
to other similarly situated management employees.
 
                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
AIP TENDER OFFER AND AIP MERGER
 
     Upon the effective date of the AIP Merger, all issued and outstanding stock
options and SARs were cancelled, and regardless of whether such stock options or
SARs had then vested or were exercisable, each holder of stock options or SARs
received cash per share equal to $18.00 less the "strike price" of such stock
options or SARs. The aggregate value of this treatment of stock options and SARs
was approximately $12.3 million.
 
     The Company's directors and executive officers received an aggregate of
approximately $10.3 million in the AIP Tender Offer and the AIP Merger in
consideration for their shares of Common Stock, stock options and SARs. Of such
$10.3 million, Mr. Hildebrand received approximately $8.0 million.
 
MANAGEMENT SERVICES AGREEMENT
 
     AIP expects to provide substantial ongoing financial and management
services to the Company utilizing the extensive operating and financial
experience of AIP's principals. AIP will receive an annual fee of $1.5 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, and will be reimbursed for out-of-pocket
expenses. The fees will be paid to AIP pursuant to a management services
agreement among AIP, Bucyrus and the Guarantors and will be subordinated in
right of payment to the Notes.
 
AIP TRANSACTION FEE
 
     At the close of the AIP Merger, AIP was paid a fee of $4.0 million and
reimbursed for out-of-pocket expenses in connection with the negotiation of the
AIP Agreement and for providing certain investment banking services to the
Company including the arrangement and negotiation of the terms of Notes and for
other financial advisory and management consulting services.
 
FUTURE AGREEMENTS WITH EXECUTIVE OFFICERS
 
     Although no specific arrangements are in place, AIP presently intends to
offer the Company's executive officers the opportunity to own up to 10% of the
Company's equity through a combination of direct investments and option
programs.
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS
 
     Von's has, pursuant to its Bylaws, established a policy indemnifying
officers and directors, to the fullest extent allowed by law, for liabilities
and expenses arising out of their actions in their capacities as officers and
directors. This provision does not exclude indemnification for liability on the
part of officers and directors under the Securities Act arising out of material
misrepresentations
 
                                       71
<PAGE>   78
 
or omissions contained in a registration statement filed under the Securities
Act. Although the Certificates of Incorporation and Bylaws of Bucyrus, Minserco,
and Boonville contain no such provisions, such indemnification is nevertheless
authorized by the Delaware General Corporation Law. However, insofar as
indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers, and controlling persons pursuant to the
foregoing provisions, the Issuers have been informed that, in the opinion of the
Commission, such indemnification is against public policy as expressed in the
Securities Act and is therefore unenforceable.
 
                             PRINCIPAL SHAREHOLDERS
 
     As a result of the AIP Merger, Bucyrus has a single shareholder, AIPAC,
whose business address is One Maritime Plaza, Suite 2525, San Francisco,
California, 94111. See "Acquisition of the Company by AIP."

                           REVOLVING CREDIT FACILITY
 
     In connection with the Private Offering, Bucyrus has entered into a new
senior bank credit agreement (the "Revolving Credit Facility") with Bank One,
Wisconsin ("Bank One"). Bank One has provided working capital and other
financing, including a letter of credit facility, to Bucyrus since 1988.
Pursuant to the Revolving Credit Facility, Bucyrus replaced its former $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 Transactions,
approximately $23.3 million would have been outstanding under the Revolving
Credit Facility. See "Capitalization." 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 of approximately $68.7 million (including the reserve referred to in (B)
in the following paragraph).
 
     The $75 million Revolving Credit Facility includes 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 is limited to a
borrowing base which is 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-process; (iv)
80% of the estimated orderly liquidation value (as determined by a formula) of
Bucyrus and domestic subsidiaries machinery and equipment; and (v) 30% of
qualified domestic net unbilled progress billing receivables minus (B) a reserve
equal to one semi-annual interest payment on the Notes. The obligations of
Bucyrus under the Revolving Credit Facility are guaranteed by certain
subsidiaries, and the Revolving Credit Facility is 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
Bucyrus, (i) Bank One's base rate or Federal Funds Rate plus 0.5% per annum plus
an applicable margin ranging from 0% to 0.5% dependent on the ratio of adjusted
funded debt to EBITDA (as defined), or (ii) LIBOR plus an applicable margin
ranging from 1.5% to 2.75% dependent on the ratio of adjusted funded debt to
EBITDA (as defined). 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 initial LIBOR margin is 2.75%.
 
     The Revolving Credit Facility contains certain restrictive covenants that
impose limitations upon, among other things, the ability of Bucyrus 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 contains covenants requiring Bucyrus (A)
to maintain certain financial ratios as follows: (i) ratio of adjusted funded
debt to EBITDA (as defined); (ii) fixed charge coverage ratio; and (iii)
interest coverage ratio; and (B) to maintain a minimum net worth.
 
     All extensions of credit under the Revolving Credit Facility are subject to
customary documentation and the continued accuracy of all representations and
warranties as well as the absence of any Material Adverse Effect or Default or
Event of Default. Capitalized terms not defined herein have the meanings set
forth in the Revolving Credit Facility.
 
     The Revolving Credit Facility may be Refinanced (as defined in the
Indenture) from time to time in accordance with the terms of the Indenture. See
"Description of the Notes -- Certain Covenants -- Limitation on Incurrence of
Indebtedness" and "-- Certain Definitions."

                            DESCRIPTION OF THE NOTES
 
GENERAL
 
     The Existing Notes were, and the Exchange Notes will be, issued pursuant to
an Indenture dated as of September 24, 1997 ("Indenture") among Bucyrus, the
Guarantors, and Harris Trust and Savings Bank, as Trustee ("Trustee"). The terms
of the Notes include those stated in the Indenture and those made part of the
Indenture by reference to the Trust Indenture Act of 1939 as in effect on the
date the Indenture is qualified thereunder (the "Trust Indenture Act" provided,
however that in the event that the Trust Indenture Act is amended after such
date, "Trust Indenture Act" means, to the extent required by any such amendment,
the Trust Indenture Act of 1939 as so amended). The Notes are subject to all
such terms, and holders of Notes are referred to the Indenture and the Trust
Indenture Act for a statement of those terms.
 
     The following is a summary of certain provisions of the Indenture and the
Notes, a copy of which Indenture and the form of Note is available upon request
to Bucyrus at the address set forth under "Available Information." The following
summary of certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all the
provisions of the Indenture, including the definitions of certain terms therein,
and those terms made a part thereof by the Trust Indenture Act. Capitalized
terms used herein and not otherwise defined have the meanings set forth under
"-- Certain Definitions."
 
     Principal of and interest on the Notes will be payable, and the Notes may
be exchanged or transferred, at the office or agency of Bucyrus in the Borough
of Manhattan, City of New York, which, unless otherwise provided by Bucyrus,
will be the offices of the Trustee. At the option of Bucyrus, payment of
interest may be made by check mailed to the addresses of holders as such
addresses appear in the Note register.
 
     The Notes are issued only in fully registered form, without coupons, in
denominations of $1,000 and any integral multiple of $1,000.
 
TERMS OF THE NOTES
 
     The Existing Notes are, and the Exchange Notes will be, general unsecured
obligations of Bucyrus, limited to $150 million aggregate principal amount, and
will mature on September 15, 2007. The Notes bear interest at the rate per annum
shown on the cover page hereof from the Issue Date, or from the most recent date
to which interest has been paid or provided for, payable semi-annually on March
15 and September 15 of each year, commencing March 15, 1998, to holders of
record at the close of business on the immediately preceding March 1 and
September 1, respectively. Bucyrus will pay interest on overdue principal at 1%
per annum in excess of such rate, and it will pay interest on overdue
installments of interest at such higher rate to the extent lawful. Interest will
be computed on the basis of a 360-day year of twelve 30-day months.
 
GUARANTEES
 
     Each of the existing and future Restricted Subsidiaries other than any
Foreign Subsidiary (the "Guarantors") has irrevocably and unconditionally
Guaranteed (the "Guarantees"), as primary obligors and not merely as sureties,
on an unsecured senior basis the performance and punctual payment when due,
whether at Stated Maturity, by acceleration or otherwise, of all obligations of
Bucyrus under the Indenture and the Notes, whether for payment of principal of
or interest on the Notes, expenses, indemnification or otherwise (all such
obligations guaranteed by the Guarantors being herein called the "Guaranteed
Obligations"). The Guarantors agreed to pay, in addition to the amount stated
above, any and all expenses (including reasonable counsel fees and expenses)
incurred by the Trustee or the Holders in enforcing any rights under the
Guarantees. Each Guarantee is limited in amount to an amount not to exceed the
maximum amount that can be Guaranteed by the applicable Guarantor without
rendering such Guarantee voidable under applicable
 
                                       74
<PAGE>   81
 
law relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally. See "Risk Factors -- Fraudulent
Conveyance Considerations."
 
     Each Guarantee is a continuing guarantee and shall (a) remain in full force
and effect until payment in full of all the Guaranteed Obligations, (b) be
binding upon each Guarantor, and (c) inure to the benefit of and be enforceable
by the Trustee, the holders and their successors, transferees and assigns. A
Guarantee will be released upon the sale (including by merger, consolidation,
combination or otherwise) of all the Capital Stock, or all or substantially all
of the assets, of the applicable Guarantor if such sale is made in compliance
with the Indenture.
 
RANKING
 
     The Existing Notes are, and the Exchange Notes will be general unsecured
obligations of Bucyrus and rank senior in right of payment to all future
Indebtedness of Bucyrus that is, by its terms, expressly subordinated in right
of payment to the Notes and pari passu in right of payment with all existing and
future unsecured obligations of Bucyrus that are not so subordinated. The
Existing Notes are, and the Exchange Notes will be fully and unconditionally
guaranteed by each domestic Restricted Subsidiary. Each Guarantee is a general
unsecured obligation of the Guarantor thereof and ranks senior in right of
payment to all future Indebtedness of such Guarantor that is, by its terms,
expressly subordinated in right of payment to such Guarantee and pari passu in
right of payment with all existing and future unsecured obligations of such
Guarantor that are not so subordinated.
 
     The Existing Notes and each Guarantee are, and the Exchange Notes will be,
effectively subordinated to secured Indebtedness of Bucyrus and the applicable
Guarantor, respectively to the extent of the assets securing such Indebtedness.
The Bank Credit Facility is secured by substantially all assets of Bucyrus and
certain of its Subsidiaries (including machinery and equipment, inventory and
receivables, other intangibles, and 65% of the stock of Bucyrus' foreign
subsidiaries) other than real property.
 
     The Existing Notes are, and the Exchange Notes will be, effectively
subordinated to all existing and future liabilities, including Indebtedness, of
Bucyrus' foreign subsidiaries. Claims of creditors of such subsidiaries,
including trade creditors, will generally have priority as to the assets of such
subsidiaries over the claims of Bucyrus and the holders of Bucyrus'
Indebtedness, including the Notes.
 
     As of June 30, 1997, on a pro forma basis after giving effect to the
Transactions (as defined) the Company would have had approximately $36.0 million
aggregate principal amount of secured indebtedness, $6.1 million of outstanding
letters of credit, and $47.0 million of undrawn borrowings under the Revolving
Credit Facility. Although the Indenture contains limitations on the amount of
additional Indebtedness that Bucyrus and the Restricted Subsidiaries may incur,
under certain circumstances the amount of such Indebtedness could be
substantial. See "-- Certain Covenants -- Limitation on Incurrence of
Indebtedness."
 
OPTIONAL REDEMPTION
 
     Except as set forth in the following paragraph, the Notes will not be
redeemable at the option of Bucyrus prior to September 15, 2002. Thereafter, the
Notes will be redeemable, at Bucyrus' option, in whole or in part, at any time
or from time to time, upon not less than 30 nor more than 60 days' prior notice
mailed by first-class mail to each holder's registered address, at the following
redemption prices (expressed in percentages of principal amount), plus accrued
and unpaid interest, if any, to the redemption date (subject to the right of
holders of record on the relevant record date to receive interest due on an
interest payment date that is on or prior to the date fixed
 
                                       75

for redemption), if redeemed during the 12-month period commencing on September
15 of the years set forth below:

2004........................................................     101.625
2005 and thereafter.........................................     100.000%
</TABLE>
 
     In addition, at any time or from time to time on or prior to September 15,
2000, Bucyrus may redeem Notes with the net cash proceeds of one or more Public
Equity Offerings following which there is a Public Market, at a redemption price
equal to 109.75% of the principal amount thereof, plus accrued and unpaid
interest, if any, to the redemption date (subject to the right of holders of
record on the relevant record date to receive interest due on an interest
payment date that is on or prior to the date fixed for redemption); provided,
however, that at least 66% of the original aggregate principal amount of the
Notes must remain outstanding immediately after each such redemption (other than
any Notes owned by Bucyrus or any of its Subsidiaries) and such redemption shall
be effected within 60 days of the consummation of the latest Public Equity
Offering.
 
     In the case of any partial redemption, selection of the Notes for
redemption will be made by the Trustee on a pro rata basis, by lot or by such
other method as the Trustee in its sole discretion shall deem to be fair and
appropriate, although no Note of $1,000 in original principal amount or less
will be redeemed in part. If any Note is to be redeemed in part only, the notice
of redemption relating to such Note shall state the portion of the principal
amount thereof to be redeemed. A new Note in principal amount equal to the
unredeemed portion thereof will be issued in the name of the holder thereof upon
cancellation of the original Note.
 
CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each holder shall have the
right to require Bucyrus to purchase all or a portion of such holder's Notes at
a purchase price in cash equal to 101% of the principal amount thereof, plus
accrued and unpaid interest, if any, to the date of purchase (subject to the
right of holders of record on the relevant record date to receive interest due
on an interest payment date that is on or prior to the date fixed for
redemption), in accordance with the provisions of the next paragraph.
 
     Within 30 days following any Change of Control, Bucyrus shall mail a notice
to each holder with a copy to the Trustee stating: (1) that a Change of Control
has occurred and that such holder has the right to require Bucyrus to purchase
such holder's Notes at the purchase price in cash equal to 101% of the principal
amount thereof plus accrued and unpaid interest, if any, to the date of purchase
(subject to the right of holders of record on the relevant record date to
receive interest on an interest payment date that is on or prior to the date
fixed for purchase); (2) the circumstances and relevant facts and relevant
financial information regarding such Change of Control; (3) the purchase date
(which shall be no earlier than 30 days nor later than 60 days from the date
such notice is mailed); and (4) the instructions as determined by Bucyrus,
consistent with the covenant described hereunder, that a holder must follow in
order to have its Notes purchased.
 
     Bucyrus shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to the covenant described
hereunder. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
Bucyrus shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.
 
                                       76
<PAGE>   83
 
     The occurrence of a Change of Control would constitute a default under the
Revolving Credit Facility. In addition, Bucyrus' ability to pay cash to the
holders upon a repurchase may be limited by Bucyrus' then existing financial
resources. There can be no assurance that sufficient funds will be available
when necessary to make any repurchases required in connection with a Change of
Control. Bucyrus' failure to purchase the Notes in connection with a Change in
Control would result in a default under the Indenture which would, in turn,
constitute a default under the Revolving Credit Facility.
 
BOOK-ENTRY, DELIVERY AND FORM
 
     Except as set forth in the next paragraph, the Existing Notes were and the
Exchange Notes will be issued in the form of one or more global notes
(collectively, the "Global Notes"). The Global Notes is deposited with, or on
behalf of, The Depository Trust Company (the "Depository") and registered in the
name of the Depository or its nominee. Except as set forth below, the Global
Notes may be transferred, in whole and not in part, only to the Depository or
another nominee of the Depository. Investors may hold their beneficial interests
in the Global Notes directly through the Depository if they have an account with
the Depository or indirectly through organizations which have accounts with the
Depository.
 
     Notes that are issued as described below under "-- Certificated Notes" will
be issued in definitive form. Upon the transfer of a Note in definitive form,
such Note will, unless the Global Notes have previously been exchanged for Notes
in definitive form, be exchanged for an interest in the Global Notes
representing the principal amount of Notes being transferred.
 
     The Depository has advised Bucyrus as follows: The Depository is a
limited-purpose trust company and organized under the laws of the State of New
York, a member of the Federal Reserve System, a "clearing corporation" within
the meaning of the New York Uniform Commercial Code, and "a clearing agency"
registered pursuant to the provisions of Section 17A of the Exchange Act. The
Depository was created to hold securities of institutions that have accounts
with the Depository ("participants") and to facilitate the clearance and
settlement of securities transactions among its participants in such securities
through electronic book-entry changes in accounts of the participants, thereby
eliminating the need for physical movement of securities certificates. The
Depository's participants include securities brokers and dealers (which may
include the Initial Purchasers), banks, trust companies, clearing corporations
and certain other organizations. Access to the Depository's book-entry system is
also available to others such as banks, brokers, dealers and trust companies
that clear through or maintain a custodial relationship with a participant,
whether directly or indirectly.
 
     Upon the issuance of the Global Notes, the Depository credited, on its
book-entry registration and transfer system, the principal amount of the Notes
represented by such Global Notes to the accounts of participants. The accounts
to be credited have been designated by the Initial Purchasers of such Notes.
Ownership of beneficial interests in the Global Notes is limited to participants
or persons that may hold interests through participants. Ownership of beneficial
interests in the Global Notes is shown on, and the transfer of those ownership
interests will be effected only through, records maintained by the Depository
(with respect to participants' interest) and such participants (with respect to
the owners of beneficial interests in the Global Notes other than participants).
The laws of some jurisdictions may require that certain purchasers of securities
take physical delivery of such securities in definitive form. Such limits and
laws may impair the ability to transfer or pledge beneficial interests in the
Global Notes.
 
     So long as the Depository, or its nominee, is the registered holder and
owner of the Global Notes, the Depository or such nominee, as the case may be,
will be considered the sole legal owner and holder of the related Notes for all
purposes of such Notes and the Indenture. Except as set forth below, owners of
beneficial interests in the Global Notes will not be entitled to have the Notes
represented by the Global Notes registered in their names, will not receive or
be entitled to receive
 
                                       77
<PAGE>   84
 
physical delivery of certificated Notes in definitive form and will not be
considered to be the owners or holders of any Notes under the Global Notes.
Bucyrus understands that under existing industry practice, in the event an owner
of a beneficial interest in the Global Notes desires to take any action that the
Depository, as the holder of the Global Notes, is entitled to take, the
Depository would authorize the participants to take such action, and that the
participants would authorize beneficial owners owning through such participants
to take such action or would otherwise act upon the instructions of beneficial
owners owning through them.
 
     Payment of principal of and interest on Notes represented by the Global
Notes registered in the name of and held by the Depository or its nominee will
be made to the Depository or its nominee, as the case may be, as the registered
owner and holder of the Global Notes.
 
     Bucyrus expects that the Depository or its nominee, upon receipt of any
payment of principal of or interest on the Global Notes, will credit
participants' accounts with payments in amounts proportionate to their
respective beneficial interests in the principal amount of the Global Notes as
shown on the records of the Depository or its nominee. Bucyrus also expects that
payments by participants to owners of beneficial interests in the Global Notes
held through such participants will be governed by standing instructions and
customary practices and will be the responsibility of such participants. Bucyrus
will not have any responsibility or liability for any aspect of the records
relating to, or payments made on account of, beneficial ownership interests in
the Global Notes for any Note or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests or for any other aspect
of the relationship between the Depository and its participants or the
relationship between such participants and the owners of beneficial interests in
the Global Notes owning through such participants.
 
     Unless and until it is exchanged in whole or in part for certificated Notes
in definitive form, the Global Notes may not be transferred except as a whole by
the Depository to a nominee of such Depository or by a nominee of such
Depository to such Depository or another nominee of such Depository.
 
     Although the Depository has agreed to the foregoing procedures in order to
facilitate transfers of interests in the Global Notes among participants of the
Depository, it is under no obligation to perform or continue to perform such
procedures, and such procedures may be discontinued at any time. Neither the
Trustee nor Bucyrus will have any responsibility for the performance by the
Depository or its participants or indirect participants of their respective
obligations under the rules and procedures governing their operations.
 
CERTIFICATED NOTES
 
     The Notes represented by the Global Notes are exchangeable for certificated
Notes in definitive form of like tenor as such Notes in denominations of U.S.
$1,000 and integral multiples thereof if (i) the Depository notifies Bucyrus
that it is unwilling or unable to continue as Depository for the Global Notes or
if at any time the Depository ceases to be a clearing agency registered under
the Exchange Act, (ii) Bucyrus in its discretion at any time determines not to
have all of the Notes represented by the Global Notes or (iii) a default
entitling holders of Notes to accelerate the maturity thereof has occurred and
is continuing. Any Note that is exchangeable pursuant to the preceding sentence
is exchangeable for certificated Notes issuable in authorized denominations and
registered in such names as the Depository shall direct. Subject to the
foregoing, the Global Notes are not exchangeable, except for Global Notes of the
same aggregate denomination to be registered in the name of the Depository or
its nominee. In addition, certificates representing Existing Notes bear a legend
as provided in the Private Offering (unless Bucyrus determines otherwise in
accordance with applicable law) subject, with respect to such Notes, to the
provisions of such legend. Holders of certificated Notes may only transfer their
Notes (i) to Bucyrus, or (ii) to a QIB; provided, however, that the agreement of
such holder is subject to any requirement of law that the disposition of such
holder's property shall at all times be and remain within its control.

CERTAIN COVENANTS
 
     The Indenture contains covenants including, among others, the following:
 
     Limitation on Incurrence of Indebtedness.
 
          (a) Bucyrus shall not, and shall not permit any Restricted Subsidiary
     to, Incur, directly or indirectly, any Indebtedness except that Bucyrus or
     any Guarantor may Incur Indebtedness if, immediately after giving effect to
     such Incurrence, the Consolidated Coverage Ratio exceeds 2.0 to 1.0.
 
          (b) The foregoing paragraph (a) will not prohibit Incurrence of the
     following Indebtedness (collectively, "Permitted Indebtedness"):
 
             (1) Indebtedness of Bucyrus or any Restricted Subsidiary Incurred
        pursuant to the Bank Credit Facility; provided, however, that, after
        giving effect to any such Incurrence, the aggregate principal amount of
        such Indebtedness then outstanding does not exceed the greater of (i)
        $75.0 million or (ii) the sum of (x) 60% of the net book value of the
        inventory of Bucyrus and the Restricted Subsidiaries and (y) 85% of the
        net book value of the accounts receivable of Bucyrus and the Restricted
        Subsidiaries, in each case determined on a consolidated basis in
        accordance with GAAP;
 
             (2) Indebtedness represented by the Notes (and the Guarantees
        thereof), and Refinancing Indebtedness thereof;
 
             (3) Indebtedness to the extent outstanding on the Issue Date (other
        than Indebtedness described in clause (1) of this paragraph or the AIP
        Bridge Loan), and Refinancing Indebtedness thereof;
 
             (4) Indebtedness of Bucyrus owed to and held by any Wholly Owned
        Subsidiary or Indebtedness of a Wholly Owned Subsidiary owed to and held
        by Bucyrus or another Wholly Owned Subsidiary; provided, however, that
        an Incurrence of Indebtedness that is not permitted by this clause (4)
        shall be deemed to have occurred upon (a) the transfer or other
        disposition of any such Indebtedness to a Person other than Bucyrus or a
        Wholly Owned Subsidiary, (b) the sale, lease, transfer or other
        disposition of shares of Capital Stock (including by consolidation or
        merger) of any Wholly Owned Subsidiary that holds Indebtedness of
        Bucyrus or any other Wholly Owned Subsidiary to a Person other than
        Bucyrus or another Wholly Owned Subsidiary, or (c) the designation of a
        Wholly Owned Subsidiary that holds Indebtedness of Bucyrus or any other
        Wholly Owned Subsidiary as an Unrestricted Subsidiary;
 
             (5) Indebtedness of Bucyrus owed to and held by any Guarantor or
        Indebtedness of a Guarantor owed to and held by Bucyrus or another
        Guarantor; provided, however, that an Incurrence of Indebtedness that is
        not permitted by this clause (5) shall be deemed to have occurred upon
        (a) the transfer or other disposition of any Indebtedness to a Person
        other than Bucyrus or a Guarantor or (b) such Guarantor's ceasing to be
        a Guarantor;
 
             (6) Hedging Obligations consisting of Interest Rate Agreements and
        Currency Agreements entered into in the ordinary course of business and
        not for the purpose of speculation; provided, however, that, in the case
        of Currency Agreements and Interest Rate Agreements, such Currency
        Agreements and Interest Rate Agreements do not increase the Indebtedness
        of Bucyrus outstanding at any time other than as a result of
        fluctuations in foreign currency exchange rates or interest rates or by
        reason of fees, indemnities and compensation payable thereunder;
 
             (7) Purchase Money Indebtedness and Capital Lease Obligations
        Incurred to finance the acquisition or improvement by Bucyrus or a
        Restricted Subsidiary of any assets
 
                                       79

        (including capital expenditures), and Refinancing Indebtedness thereof,
        in an aggregate principal amount not to exceed $10.0 million at any time
        outstanding;
 
             (8) Indebtedness of any Foreign Subsidiary Incurred for the working
        capital purposes of such Foreign Subsidiary, and Refinancing
        Indebtedness thereof, in an aggregate principal amount not to exceed
        $15.0 million at any time outstanding;
 
             (9) Indebtedness of Bucyrus or any Restricted Subsidiary
        constituting lease payments or guarantees of lease payments or similar
        obligations of a customer of Bucyrus or a Restricted Subsidiary in
        connection with a Leasing Program, and Refinancing Indebtedness thereof,
        in an aggregate principal amount not to exceed $10.0 million at any time
        outstanding; and
 
             (10) Indebtedness of Bucyrus or any Restricted Subsidiary in
        addition to that described in clauses (1) through (9) above, so long as
        the aggregate principal amount of all such Indebtedness incurred
        pursuant to this clause (10) does not exceed $10.0 million at any time
        outstanding.
 
          (c) Notwithstanding the foregoing, Bucyrus shall not, and shall not
     permit any Guarantor to, Incur any Indebtedness that purports to be by its
     terms (or by the terms of any agreement or instrument governing such
     Indebtedness) subordinated to any other Indebtedness of Bucyrus or of such
     Guarantor, as the case may be, unless such Indebtedness is also by its
     terms (or by the terms of the agreement or instrument governing such
     Indebtedness) made expressly subordinated to the Notes or the Guarantee of
     such Guarantor, as applicable, to at least the same extent as such
     Indebtedness is subordinated to such other Indebtedness of Bucyrus or such
     Guarantor, as applicable.
 
     Limitation on Restricted Payments.
 
          (a) Bucyrus shall not, and shall not permit any Restricted Subsidiary,
     directly or indirectly, to declare or make a Restricted Payment if:
 
             (1) a Default shall have occurred and be continuing (or would
        result therefrom);
 
             (2) immediately after giving effect to the proposed Restricted
        Payment, Bucyrus is not able to Incur an additional $1.00 of
        Indebtedness pursuant to paragraph (a) of the covenant described under
        "-- Limitation on Incurrence of Indebtedness" above; or
 
             (3) the aggregate amount of such Restricted Payment together with
        all other Restricted Payments (the amount of any payments made in
        property other than cash to be valued at the fair market value of such
        property, as determined in good faith by the Board of Directors)
        declared or made since the Issue Date (other than any Restricted Payment
        described in clause (ii), (iii) or (iv) of paragraph (b) below) would
        exceed the sum (the "Basket") of:
 
                (A) 50% of the Consolidated Net Income accrued during the period
           (treated as one accounting period) from the beginning of the fiscal
           quarter immediately following the fiscal quarter during which the
           Notes are originally issued to the end of the most recent fiscal
           quarter prior to the date of such Restricted Payment for which
           financial statements are available (or, in case such Consolidated Net
           Income accrued during such period (treated as one accounting period)
           shall be a deficit, minus 100% of such deficit);
 
                (B) the aggregate Net Cash Proceeds received by Bucyrus from the
           issuance or sale (other than to a Subsidiary of Bucyrus) of Qualified
           Stock subsequent to the Issue Date;
 
                                       80
<PAGE>   87
 
                (C) the principal amount (or accreted value, if less) by which
           Indebtedness of Bucyrus or any Restricted Subsidiary is reduced on
           Bucyrus' balance sheet upon the conversion or exchange (other than by
           a Subsidiary of Bucyrus) subsequent to the Issue Date into Qualified
           Stock (less the amount of any cash, or the fair value of any other
           property, distributed by Bucyrus or any Restricted Subsidiary upon
           such conversion or exchange); and
 
                (D) to the extent not included in the calculation of the
           Consolidated Net Income referred to in (A), an amount equal to the
           sum of (i) the net reduction in Investments in Unrestricted
           Subsidiaries resulting from dividends, repayments of loans or
           advances or other transfers of assets subsequent to the Issue Date,
           in each case to Bucyrus or any Restricted Subsidiary from
           Unrestricted Subsidiaries, and (ii) the portion (proportionate to
           Bucyrus' equity interest in such Subsidiary) of the fair market value
           of the net assets of an Unrestricted Subsidiary at the time such
           Unrestricted Subsidiary is redesignated a Restricted Subsidiary;
           provided, however, that the foregoing sum shall not exceed, in the
           case of any Unrestricted Subsidiary, the amount of Investments
           previously made (and treated as a Restricted Payment) by Bucyrus or
           any Restricted Subsidiary in such Unrestricted Subsidiary;
 
     provided, however, that the AIP Equity Contribution shall not increase the
     Basket.
 
          (b) The provisions of the foregoing paragraph (a) shall not prohibit
     the following actions: (i) dividends paid within 60 days after the date of
     declaration thereof if at such date of declaration such dividend would have
     been permitted under the Indenture; (ii) any repurchase, redemption,
     retirement or other acquisition of Capital Stock or Subordinated
     Obligations of Bucyrus made in exchange for, or out of the proceeds of the
     substantially concurrent sale (other than to a Subsidiary of Bucyrus) of,
     Qualified Stock or, with respect to any such Subordinated Obligations, in
     exchange for or out of the proceeds of the substantially concurrent sale
     (other than to a Subsidiary of Bucyrus) of other Subordinated Obligations
     of Bucyrus; provided, however, that such exchange or sale shall not
     increase the Basket; (iii) any repurchase, redemption, retirement or other
     acquisition of Capital Stock of Bucyrus held by officers, directors and
     employees of Bucyrus or any Restricted Subsidiary upon such persons' death,
     retirement or other termination of employment or directorship, as the case
     may be; provided, however, that the aggregate amount of Restricted Payments
     pursuant to this clause (iii) shall not exceed $5.0 million; and (iv)
     Restricted Payments not to exceed $5.0 million in the aggregate since the
     Issue Date; provided, however, that in the case of clauses (ii), (iii) and
     (iv), no Default shall have occurred and be continuing or would arise
     therefrom.
 
     Limitation on Liens. Bucyrus shall not, and shall not permit any Restricted
Subsidiary to, directly or indirectly, Incur or permit to exist any Lien (other
than Permitted Liens) of any nature whatsoever on any property of Bucyrus or any
Restricted Subsidiary (including Capital Stock of a Restricted Subsidiary),
whether owned at the Issue Date or thereafter acquired, or any income or profits
therefrom or assign or convey any right to receive income therefrom, unless the
Notes and the Guarantees are secured on an equal and ratable basis with the
obligations so secured until such time as such obligations are no longer secured
by a Lien (and if the obligations so secured are subordinated to the Notes and
the Guarantees, the Lien securing such obligations are also so subordinated at
least to the same extent).
 
     Limitation on Transactions with Affiliates.
 
          (a) Bucyrus shall not, and shall not permit any Restricted Subsidiary
     to, directly or indirectly, enter into or permit to exist any transaction
     or series of related transactions (including, without limitation, the
     purchase, sale, lease or exchange of any property, employee compensation
     arrangements or the rendering of any service) with any Affiliate of Bucyrus
     (an "Affiliate Transaction") unless the terms thereof (1) are no less
     favorable to Bucyrus or such
 
                                       81
<PAGE>   88
 
     Restricted Subsidiary than those that could be obtained at the time of such
     transaction in arm's-length dealings with a Person who is not such an
     Affiliate, (2) if such Affiliate Transaction involves aggregate value in
     excess of $1.0 million in any one year, (i) are set forth in writing, (ii)
     comply with clause (1), and (iii) have been approved by a majority of the
     Independent Directors, and (3) if such Affiliate Transaction involves
     aggregate value in excess of $5.0 million in any one year, (i) comply with
     clause (2), and (ii) have been determined by a nationally recognized
     investment banking, appraisal, valuation or accounting firm to be fair,
     from a financial standpoint, to Bucyrus and the Restricted Subsidiaries.
 
          (b) The provisions of the foregoing paragraph (a) shall not prohibit
     (i) any Restricted Payment permitted to be made pursuant to the covenant
     described under "-- Limitation on Restricted Payments," (ii) any issuance
     of securities or other payments, awards or grants in cash, securities or
     otherwise, pursuant to, or the funding of, employment arrangements, stock
     options and stock ownership plans in the ordinary course of business (as
     determined in good faith by the Board of Directors) and approved by the
     Board of Directors, (iii) the grant of stock options or similar rights to
     employees and directors of Bucyrus in the ordinary course of business (as
     determined in good faith by the Board of Directors) and pursuant to plans
     approved by the Board of Directors, (iv) loans or advances to employees in
     the ordinary course of business of Bucyrus and the Restricted Subsidiaries,
     (v) fees, compensation or employee benefit arrangements paid to and
     indemnity provided for the benefit of directors, officers or employees of
     Bucyrus or any Subsidiary in the ordinary course of business, (vi) any
     transaction solely between or among Bucyrus and/or one or more Guarantors
     and/or Wholly Owned Subsidiaries, (vii) performance or discharge by Bucyrus
     of its obligations under agreements as in effect on the Issue Date, (viii)
     repayment of the AIP Bridge Loan upon consummation of the AIP Merger or
     (ix) payment of $4.0 million to AIP in connection with the AIP Merger or
     payment of fees to AIP pursuant to the Management Agreement in an amount
     not to exceed $1.5 million per year.
 
     Limitation on Sales of Assets and Subsidiary Stock. Bucyrus shall not, and
shall not permit any Restricted Subsidiary to, consummate any Asset Disposition
unless (i) Bucyrus or such Restricted Subsidiary, as the case may be, receives
consideration at the time of such Asset Disposition at least equal to the fair
market value (including as to the value of all non-cash consideration), as
determined in good faith by the Board of Directors, of the assets or other
property subject to such Asset Disposition, and (ii) at least 75% of the
consideration therefor received by Bucyrus or such Restricted Subsidiary is in
the form of cash or Temporary Cash Investments. For the purposes of this
covenant, the following are deemed to be cash: (x) amount of any liabilities
(other than liabilities that are subordinated to any other Indebtedness of
Bucyrus or such Restricted Subsidiary, as the case may be) of Bucyrus or such
Restricted Subsidiary (as shown on Bucyrus' or such Restricted Subsidiary's most
recent balance sheet or in the notes thereto) that are assumed by the transferee
of any such assets or other property in such Asset Disposition, but only to the
extent that such assumption is effected on a basis under which there is no
further recourse to Bucyrus or any Restricted Subsidiary with respect to such
liabilities and (y) securities received by Bucyrus or any Restricted Subsidiary
from the transferee that are immediately converted by Bucyrus or such Restricted
Subsidiary into cash.
 
     With respect to any Asset Disposition occurring on or after the Issue Date
from which Bucyrus or any Restricted Subsidiary receives Net Available Cash,
Bucyrus or such Restricted Subsidiary may within 270 days after the date such
Net Available Cash is received: (i) apply an amount equal to such Net Available
Cash to permanently prepay, repay or purchase Indebtedness under the Bank Credit
Facility; or (ii) invest an equal amount, or the amount not so applied pursuant
to clause (i), in Additional Assets (including by means of an Investment in
Additional Assets by a Restricted Subsidiary with Net Available Cash received by
Bucyrus or another Restricted Subsidiary). The amount of Net Available Cash not
applied pursuant to clause (ii) above shall constitute "Excess
 
                                       82
<PAGE>   89
 
Proceeds." Pending application of Net Available Cash pursuant to this provision,
such Net Available Cash shall be invested in Temporary Cash Investments.
 
     If at any time the aggregate amount of Excess Proceeds not theretofore
subject to an Excess Proceeds Offer (as defined below) totals at least $5.0
million, Bucyrus shall, not later than 10 business days after the end of the
period during which Bucyrus is required to apply such Excess Proceeds pursuant
to clause (i) of the immediately preceding paragraph (or, if Bucyrus so elects,
at any time within such period), make an offer (an "Excess Proceeds Offer") to
purchase from the holders of Notes and Other Qualified Notes (determined on a
pro rata basis according to the accreted value or principal amount, as the case
may be, of the Notes and the Other Qualified Notes) that may be purchased out of
the Excess Proceeds (rounded down to the nearest multiple of $1,000) on such
date, at a purchase price (x) in the case of the Notes, equal to 100% of the
principal amount of such Notes, plus accrued and unpaid interest, if any, to the
date of purchase and (y) in the case of each issue of Other Qualified Notes,
based on the terms set forth in the indenture related to such issue. Upon
completion of an Excess Proceeds Offer the amount of Excess Proceeds remaining
after application pursuant to such Excess Proceeds Offer (including payment of
the purchase price for Notes and Other Qualified Notes duly tendered) may be
used by Bucyrus for any corporate purpose (to the extent not otherwise
prohibited by the Indenture).
 
     Bucyrus shall comply, to the extent applicable, with the requirements of
Section 14(e) of the Exchange Act and any other securities laws or regulations
thereunder in the event that such Excess Proceeds are received by Bucyrus under
the covenant described hereunder and Bucyrus is required to repurchase Notes as
described above. To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
Bucyrus shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.
 
     Limitation on Dividend and Other Restrictions Affecting Restricted
Subsidiaries. Bucyrus shall not, and shall not permit any Restricted Subsidiary
to, directly or indirectly, create or otherwise cause or permit to exist or
become effective any consensual encumbrance or consensual restriction on the
ability of any Restricted Subsidiary (i) to pay dividends or make any other
distributions on its Capital Stock to Bucyrus or any other Restricted Subsidiary
or pay any Indebtedness owed to Bucyrus or any other Restricted Subsidiary, (ii)
to make any loans or advances to, or guarantee any Indebtedness of, Bucyrus or
any other Restricted Subsidiary, or (iii) transfer any of its property or assets
to Bucyrus or any other Restricted Subsidiary, except: (A) any encumbrance or
restriction pursuant to an agreement in effect at or entered into on the Issue
Date (including, without limitation, the Bank Credit Facility), as such
encumbrance or restriction is in effect on the Issue Date; (B) any encumbrance
or restriction with respect to a Restricted Subsidiary pursuant to an agreement
relating to any Indebtedness Incurred by such Restricted Subsidiary which was
entered into on or prior to the date on which such Restricted Subsidiary was
acquired by Bucyrus (other than as consideration in, or to provide all or any
portion of the funds or credit support utilized to consummate, the transaction
or series of related transactions pursuant to which such Restricted Subsidiary
became a Restricted Subsidiary or was acquired by Bucyrus) and outstanding on
such date; (C) any encumbrance or restriction pursuant to an agreement effecting
a Refinancing of Indebtedness Incurred pursuant to an agreement referred to in
clause (A) or (B) of this covenant (or effecting a Refinancing of such
Refinancing Indebtedness pursuant to this clause (C)) or contained in any
amendment to an agreement referred to in clause (A) or (B) of this covenant or
this clause (C); provided, however, that the encumbrances and restrictions with
respect to such Restricted Subsidiary contained in any such refinancing
agreement or amendment are no more restrictive in any material respect than the
encumbrances and restrictions with respect to such Restricted Subsidiary
contained in such agreements; (D) any such encumbrance or restriction consisting
of customary non-assignment provisions in leases governing leasehold interests
to the extent such provisions restrict the transfer of the lease or the property
leased thereunder; (E) restrictions contained in security agreements or
mortgages on property acquired in the ordinary
 
                                       83
<PAGE>   90
 
course of business to the extent such restrictions restrict the transfer of the
property subject to such security agreements or mortgages; (F) any restriction
with respect to a Restricted Subsidiary imposed pursuant to an agreement entered
into for the sale or disposition of the Capital Stock or assets of such
Restricted Subsidiary; provided, however, that such restriction is applicable
only to such Capital Stock or assets, as applicable, and such sale or
disposition otherwise is permitted under the covenant described under "--
Limitation on Sales of Assets and Subsidiary Stock" and (G) any restriction
imposed by applicable law.
 
     Limitation on the Issuance or Sale of Capital Stock of Wholly Owned
Subsidiaries. Bucyrus (i) will not, and will not permit any Wholly Owned
Subsidiary (other than any Guarantor) to, transfer, convey, sell, lease or
otherwise dispose of any Capital Stock of any Wholly Owned Subsidiary (other
than any Guarantor) to any Person (other than Bucyrus or another Wholly Owned
Subsidiary), unless (a) such transfer, conveyance, sale, lease or other
disposition consists of all of the Capital Stock of such Wholly Owned Subsidiary
and (b) the net cash proceeds from such transfer, conveyance, sale, lease or
other disposition are applied in accordance with the covenant described above
under "Limitation on Sales of Assets and Subsidiary Stock," and (ii) will not
permit any Wholly Owned Subsidiary to issue any Capital Stock (other than, if
necessary, shares constituting directors' qualifying shares) to any Person other
than to Bucyrus or another Wholly Owned Subsidiary.
 
     Limitation on Sale and Leaseback Transactions. Bucyrus will not, and will
not permit any Restricted Subsidiary to, enter into any Sale and Leaseback
Transaction; provided, however, that Bucyrus may enter into a Sale and Leaseback
Transaction if (i) Bucyrus could have (a) Incurred Indebtedness in an amount
equal to the Attributable Debt relating to such Sale and Leaseback Transaction
pursuant to the covenant described under "-- Limitation on Incurrence of
Indebtedness," and (b) Incurred a Lien to secure such Indebtedness pursuant to
the covenant described under "-- Limitation on Liens," (ii) the gross cash
proceeds of such Sale and Leaseback Transaction are at least equal to the fair
market value (as determined in good faith by the Board of Directors and set
forth in an Officers' Certificate delivered to the Trustee) of the property that
is the subject of such Sale and Leaseback Transaction and (iii) the transfer of
assets in such Sale and Leaseback Transaction is permitted by, and Bucyrus
applies the proceeds of such transaction in compliance with, the covenant
described under "-- Limitation on Sales of Assets and Subsidiary Stock."
 
     Merger, Consolidation and Sale of Assets. Bucyrus shall not consolidate
with or merge with or into, or convey, transfer or lease, in one transaction or
a series of transactions, all or substantially all its assets to, any Person,
unless: (i) the resulting, surviving or transferee Person (the "Successor
Company"), whether or not Bucyrus, shall be a Person organized and existing
under the laws of the United States of America, any State thereof or the
District of Columbia and the Successor Company (if not Bucyrus) shall expressly
assume, by an indenture supplemental thereto, executed and delivered to the
Trustee, in form satisfactory to the Trustee, all the obligations of Bucyrus
under the Notes, the Indenture and the Registration Agreement; (ii) immediately
after giving effect to such transaction (and treating any Indebtedness which
becomes an obligation of the Successor Company or any Subsidiary as a result of
such transaction as having been Incurred by such Successor Company or such
Subsidiary at the time of such transaction), no Default shall have occurred and
be continuing; (iii) except in the case of a merger the sole purpose of which is
to change Bucyrus' jurisdiction of incorporation, immediately after giving
effect to such transaction, the Successor Company would be able to Incur an
additional $1.00 of Indebtedness pursuant to paragraph (a) of the covenant
described under "-- Limitation on Incurrence of Indebtedness" (treating the
Successor Company as Bucyrus); (iv) immediately after giving effect to such
transaction, the Successor Company shall have Consolidated Net Worth in an
amount that is not less than the Consolidated Net Worth of Bucyrus immediately
prior to such transaction; and (v) Bucyrus shall have delivered to the Trustee
an Officers' Certificate and an Opinion of Counsel, each stating that such
consolidation, merger or transfer and such supplemental indenture (if any)
comply with the Indenture.
 
                                       84
<PAGE>   91
 
Notwithstanding the foregoing clauses (ii), (iii) and (iv), any Restricted
Subsidiary may consolidate with, merge into or transfer all or part of its
properties and assets to Bucyrus.
 
     The Successor Company shall be the successor to Bucyrus and shall succeed
to, and be substituted for, and may exercise every right and power of, Bucyrus
under the Indenture, but the predecessor Company in the case of a conveyance,
transfer or lease shall not be released from the obligation to pay the principal
of and interest on the Notes.
 
     SEC Reports.  Whether or not Bucyrus is then subject to Section 13(a) or
15(d) of the Exchange Act, Bucyrus shall file with the Commission, so long as
the Notes are outstanding, the annual reports, quarterly reports and other
periodic reports that Bucyrus would be required to file with the Commission
pursuant to Section 13(a) or 15(d) if Bucyrus were so subject, and such
documents shall be filed with the Commission on or prior to the respective dates
(the "Required Filing Dates") by which Bucyrus would be required so to file such
documents if Bucyrus were so subject, unless, in any case, such filing is not
then permitted by the Commission. Bucyrus will also in any event (i) within 15
days of each Required Filing Date, (a) transmit by mail to holders of Notes, as
their names and addresses appear in the Note register, without cost to such
holders, and (b) file with the Trustees copies of the annual reports, quarterly
reports and other periodic reports that Bucyrus would be required to file with
the Commission pursuant to Section 13(a) or 15(d) of the Exchange Act if Bucyrus
were subject to such Section 13(a) or 15(d), and (ii) if such filing with
Commission is not then permitted by the Commission promptly upon written
request, supply copies of such documents to any prospective holder at Bucyrus'
cost.
 
EVENTS OF DEFAULT
 
     Any of the following shall constitute an Event of Default:
 
          (i) default for 30 days in the payment when due of interest on any
     Note;
 
          (ii) default in the payment when due of principal on any Note, whether
     upon maturity, acceleration, optional redemption, required repurchase or
     otherwise;
 
          (iii) failure to perform or comply with any covenant, agreement or
     warranty in the Indenture (other than any specified in clause (i) or (ii)
     above) which failure continues for 30 days after written notice thereof has
     been given to Bucyrus by the Trustee or to Bucyrus and the Trustee by the
     holders of at least 25% in aggregate principal amount of the then
     outstanding Notes;
 
          (iv) default under any mortgage, indenture or instrument under which
     there may be issued or by which there may be secured or evidenced any
     Indebtedness for money borrowed by Bucyrus or any Restricted Subsidiary
     whether such Indebtedness now exists, or is created after the Issue Date,
     which default (x)(a) is caused by a failure to pay such Indebtedness at
     Stated Maturity (giving effect to any grace period related thereto) (a
     "Payment Default") or (b) results in the acceleration of such Indebtedness
     prior to its stated maturity and (y) in each case, the principal amount of
     any such Indebtedness as to which a Payment Default or acceleration shall
     have occurred, together with the principal amount of any other such
     Indebtedness under which there has been a Payment Default or the maturity
     of which has been so accelerated, aggregates $10.0 million or more;
 
          (v) one or more judgments, orders or decrees for the payment of money
     of $10.0 million or more, individually or in the aggregate, shall be
     entered against Bucyrus or any Restricted Subsidiary or any of their
     respective properties and which judgments, orders or decrees are not paid,
     discharged, bonded or stayed within 60 days after their entry;
 
          (vi) certain events of bankruptcy, dissolution, insolvency,
     reorganization, administration or similar proceedings with respect to
     Bucyrus, any Significant Restricted Subsidiary or any group of Restricted
     Subsidiaries that together would constitute a Significant Restricted
     Subsidiary; or
 
                                       85
<PAGE>   92
 
          (vii) any Guarantee ceases to be in full force and effect (other than
     in accordance with its terms or the Indenture) or any Guarantor denies or
     disaffirms its obligations under its Guarantee.
 
     If an Event of Default occurs and is continuing (other than an Event of
Default described in clause (vi) above with respect to Bucyrus), the Trustee or
the holders of at least 25% in principal amount of the outstanding Notes may
declare the principal of and accrued but unpaid interest on all the Notes to be
due and payable. Upon such a declaration, such principal and interest shall be
due and payable immediately. If an Event of Default described in clause (vi)
above occurs with respect to Bucyrus, the principal of and interest on all the
Notes will ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders of the Notes.
Under certain circumstances, the Holders of a majority in principal amount of
the outstanding Notes may rescind any such acceleration with respect to the
Notes and its consequences.
 
     Except to enforce the right to receive payment of principal or interest
when due, no holder may pursue any remedy with respect to the Indenture or the
Notes unless (i) such holder has previously given the Trustee notice that an
Event of Default is continuing, (ii) holders of at least 25% in principal amount
of the outstanding Notes have requested the Trustee to pursue the remedy, (iii)
such holders have offered the Trustee reasonable security or indemnity against
any loss, liability or expense, (iv) the Trustee has not complied with such
request within 60 days after the receipt thereof and the offer of security or
indemnity and (v) the holders of a majority in principal amount of the
outstanding Notes have not given the Trustee a direction inconsistent with such
request within such 60-day period. Subject to certain restrictions, the holders
of a majority in principal amount of the outstanding Notes are given the right
to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee or of exercising any trust or power conferred on the
Trustee. The Trustee, however, may refuse to follow any direction that conflicts
with law or the Indenture or that the Trustee determines is unduly prejudicial
to the rights of any other holder or that would involve the Trustee in personal
liability.
 
     The Indenture provides that if a Default occurs and is continuing and is
known to the Trustee, the Trustee must mail to each holder notice of the Default
within 90 days after it occurs. Notwithstanding the foregoing, except in the
case of a Default in the payment of principal of or interest on any Note, the
Trustee may withhold notice if and so long as a committee of its trust officers
determines that withholding notice is in the interest of the holders. In
addition, Bucyrus is required to deliver to the Trustee, within 120 days after
the end of each fiscal year, a certificate indicating whether the signers
thereof know of any Default that occurred during the previous year. Bucyrus also
is required to deliver to the Trustee, within 30 days after the occurrence
thereof, written notice of any event which would constitute certain Defaults,
their status and what action Bucyrus is taking or proposes to take in respect
thereof.
 
AMENDMENTS AND WAIVERS
 
     Subject to certain exceptions, the Indenture may be amended with the
consent of the holders of a majority in principal amount of the Notes then
outstanding (including consents obtained in connection with a tender offer or
exchange for the Notes) and any past default or compliance with any provisions
may also be waived with the consent of the holders of a majority in principal
amount of the Notes then outstanding. However, without the consent of each
holder of an outstanding Note affected thereby, no amendment may, among other
things, (i) reduce the principal amount of Notes whose holders must consent to
an amendment, supplement or waiver; (ii) reduce the principal of or change the
fixed maturity of any Note, or alter the provisions with respect to the
redemption or repurchase provisions of any Note or the Indenture in a manner
adverse to the holders of the Notes (other than the provisions of the Indenture
relating to any offer to purchase required under the covenants described under
"-- Certain Covenants -- Limitation on Sales of Assets and Subsidiary Stock" or
"-- Change of Control"); (iii) reduce the rate of or change the time for payment
of interest on any Note; (iv) waive a Default in the payment of principal or
interest on, the Notes
 
                                       86
<PAGE>   93
 
(except that holders of at least a majority in aggregate principal amount of the
then outstanding Notes may (x) rescind an acceleration of the Notes that
resulted from a non-payment default and (y) waive the payment default that
resulted from such acceleration); (v) make any Note payable in money other than
that stated in the Notes; (vi) make any change in the provisions of the
Indenture relating to waivers of past Defaults or the rights of holders of Notes
to receive payments of principal of or interest on, the Notes; (vii) waive a
redemption payment with respect to any Note; (viii) release any Guarantor from
its Guarantee except in compliance with the Indenture or (ix) make any change in
the foregoing amendment and waiver provisions; provided, further, however, that
no such modification or amendment may, without the consent of the holders of
two-thirds of the aggregate principal amount of Notes affected thereby, modify
any of the provisions (including the definitions thereto) relating to the
covenant described under "-- Change of Control" in a manner materially adverse
to the holders.
 
     Without the consent of any holder, Bucyrus and Trustee may amend the
Indenture to cure any ambiguity, defect or inconsistency, to provide for the
assumption by a successor corporation of the obligations of Bucyrus under the
Indenture in the event of any transaction in compliance with the covenant
described under "-- Certain Covenants -- Merger, Consolidation and Sale of
Assets" in which Bucyrus is not the Surviving Person, to provide for
uncertificated Notes in addition to or in place of certificated Notes (provided
that the uncertificated Notes are issued in registered form for purposes of
Section 163(f) of the Code, or in a manner such that the uncertificated Notes
are as described in Section 163(f)(2)(B) of the Code), to add Guarantees with
respect to the Notes, to release Guarantors when permitted by the Indenture, to
secure the Notes, to add to the covenants of Bucyrus for the benefit of the
holders or to surrender any right or power conferred upon Bucyrus, to make any
change that does not adversely affect the rights of any holder or to comply with
any requirement of the SEC in connection with the qualification of the Indenture
under the Trust Indenture Act.
 
     The consent of the holders is not necessary under the Indenture to approve
the particular form of any proposed amendment. It is sufficient if such consent
approves the substance of the proposed amendment.
 
     After an amendment under the Indenture becomes effective, Bucyrus is
required to mail to holders a notice briefly describing such amendment. However,
the failure to give such notice to all holders, or any defect therein, will not
impair or affect the validity of the amendment.
 
TRANSFER
 
     Notes are issued in registered form and are transferable only upon the
surrender of the Notes being transferred for registration of transfer. No
service charge will be made for any registration of transfer or exchange of
Notes, but Bucyrus may require payment of a sum sufficient to cover any transfer
tax or other similar governmental charge payable in connection therewith.
 
DISCHARGE OF INDENTURE AND DEFEASANCE
 
     When (i) Bucyrus delivers to the Trustee all outstanding Notes (other than
Notes replaced because of mutilation, loss, destruction or wrongful taking) for
cancellation or (ii) all outstanding Notes have become due and payable, whether
at maturity or as a result of the mailing of a notice of redemption as described
above, and Bucyrus irrevocably deposits with the Trustee funds sufficient to pay
at maturity or upon redemption all outstanding Notes, including interest
thereon, and if in either case Bucyrus pays all other sums payable hereunder by
Bucyrus, then the Indenture shall, subject to certain surviving provisions,
cease to be of further effect. The Trustee shall acknowledge satisfaction and
discharge of the Indenture on demand of Bucyrus accompanied by an Officers'
Certificate and an Opinion of Counsel and at the cost and expense of Bucyrus.
 
     Subject to the conditions to defeasance described below and in the
Indenture and the survival of certain provisions, Bucyrus at any time may
terminate (i) all its obligations under the Notes and the
 
                                       87
<PAGE>   94
 
Indenture ("legal defeasance option") or (ii) its obligations under certain
restrictive covenants and the related Events of Default ("covenant defeasance
option"). Bucyrus may exercise its legal defeasance option notwithstanding its
prior exercise of its covenant defeasance option.
 
     If Bucyrus exercises its legal defeasance option, payment of the Notes may
not be accelerated because of an Event of Default. If Bucyrus exercises its
covenant defeasance option, payment of the Notes may not be accelerated because
of an Event of Default referred to in clause (ii) of the immediately preceding
paragraph.
 
     In order to exercise either defeasance option, Bucyrus must irrevocably
deposit in trust (the "defeasance trust") with the Trustee money or U.S.
Government Obligations for the payment of principal and interest on the Notes to
redemption or maturity, as the case may be, and must comply with certain other
conditions, including delivery to the Trustee of an Opinion of Counsel to the
effect that holders of the Notes will not recognize income, gain or loss for
Federal income tax purposes as a result of such deposit and defeasance and will
be subject to Federal income tax on the same amount and in the same manner and
at the same times as would have been the case if such deposit and defeasance had
not occurred (and, in the case of legal defeasance only, such Opinion of Counsel
must be based on a ruling of the Internal Revenue Service or change in
applicable Federal income tax law).
 
CONCERNING THE TRUSTEE
 
     Harris Trust and Savings Bank is the Trustee under the Indenture and has
been appointed by Bucyrus as Registrar and Paying Agent with regard to the
Notes.
 
     The holders of a majority in principal amount of the outstanding Notes will
have the right to direct the time, method and place of conducting any proceeding
for exercising any remedy available to the Trustee, subject to certain
exceptions. The Indenture provides that if an Event of Default occurs (and is
not cured), the Trustee will be required, in the exercise of its power, to use
the degree of care of a prudent person in the conduct of such person's own
affairs. Subject to such provisions, the Trustee will be under no obligation to
exercise any of its rights or powers under the Indenture at the request of any
holder of Notes, unless such holder shall have offered to the Trustee security
and indemnity satisfactory to it against any loss, liability or expense and then
only to the extent required by the terms of the Indenture.
 
GOVERNING LAW
 
     The Indenture provides that it and the Notes are to be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to principles of conflicts of law to the extent that the application of
the law of another jurisdiction would be required thereby.

<PAGE>   97
 
which financial statements are available to (ii) Consolidated Fixed Charges for
such four fiscal quarters; provided, however, that (1) if Bucyrus or any
Restricted Subsidiary has Incurred any Indebtedness since the beginning of such
period that remains outstanding on such date of determination or if the
transaction giving rise to the need to calculate the Consolidated Coverage Ratio
is an Incurrence of Indebtedness, or both, EBITDA and Consolidated Fixed Charges
for such period shall be calculated after giving effect on a pro forma basis to
such Indebtedness as if such Indebtedness had been Incurred on the first day of
such period and the discharge of any other Indebtedness repaid, repurchased,
defeased or otherwise discharged with the proceeds of such new Indebtedness as
if such discharge had occurred on the first day of such period (except that, in
the case of Indebtedness used to finance working capital needs incurred under a
revolving credit or similar arrangement, the amount thereof shall be deemed to
be the average daily balance of such Indebtedness during such
four-fiscal-quarter period), (2) if since the beginning of such period Bucyrus
or any Restricted Subsidiary shall have made any Asset Disposition, the EBITDA
for such period shall be reduced by an amount equal to the EBITDA (if positive)
directly attributable to the assets which are the subject of such Asset
Disposition for such period, or increased by an amount equal to the EBITDA (if
negative) directly attributable thereto for such period, and Consolidated Fixed
Charges for such period shall be reduced by an amount equal to the Consolidated
Fixed Charges directly attributable to any Indebtedness of Bucyrus or any
Restricted Subsidiary repaid, repurchased, defeased, assumed by a third person
(to the extent Bucyrus and its Restricted Subsidiaries are no longer liable for
such Indebtedness) or otherwise discharged with respect to Bucyrus and its
continuing Restricted Subsidiaries in connection with such Asset Disposition for
such period (or, if the Capital Stock of any Restricted Subsidiary is sold, the
Consolidated Fixed Charges for such period directly attributable to the

continuing Restricted Subsidiaries are no longer liable for such Indebtedness
after such sale), (3) if since the beginning of such period Bucyrus shall have
consummated a Public Equity Offering following which there is a Public Market,
Consolidated Fixed Charges for such period shall be reduced by an amount equal
to the Consolidated Fixed Charges directly attributable to any Indebtedness of
Bucyrus or any Restricted Subsidiary repaid, repurchased, defeased or otherwise
discharged with respect to Bucyrus and its Restricted Subsidiaries in connection
with such Public Equity Offering for such period, (4) if since the beginning of
such period Bucyrus or any Restricted Subsidiary (by merger or otherwise) shall
have made an Investment in any Restricted Subsidiary (or any Person which
becomes a Restricted Subsidiary) or an acquisition of assets, which acquisition
constitutes all or substantially all of an operating unit of a business,
including any such Investment or acquisition occurring in connection with a
transaction requiring a calculation to be made hereunder, EBITDA and
Consolidated Fixed Charges for such period shall be calculated after giving pro
forma effect thereto (including the Incurrence of any Indebtedness) as if such
Investment or acquisition occurred on the first day of such period and (5) if
since the beginning of such period any Person (that subsequently became a
Restricted Subsidiary or was merged with or into Bucyrus or any Restricted
Subsidiary since the beginning of such period) shall have made any Asset
Disposition, any Investment or acquisition of assets that would have required an
adjustment pursuant to clause (3) or (4) above if made by Bucyrus or a
Restricted Subsidiary during such period, EBITDA and Consolidated Fixed Charges
for such period shall be calculated after giving pro forma effect thereto as if
such Asset Disposition, Investment or acquisition occurred on the first day of
such period. For purposes of this definition, whenever pro forma effect is to be
given to an acquisition of assets, the amount of income, earnings or expense
relating thereto and the amount of Consolidated Fixed Charges associated with
any Indebtedness Incurred in connection therewith, the pro forma calculations
shall be prepared in accordance with Article II of Regulation S-X promulgated by
the Commission as determined in good faith by a responsible financial or
accounting Officer of Bucyrus. If any Indebtedness bears a floating rate of
interest and is being given pro forma effect, the interest of such Indebtedness
shall be calculated as if the rate in effect on the date of determination had
been the applicable rate for the entire period (taking into account any Interest
Rate Agreement applicable to such Indebtedness if such Interest Rate Agreement
has a remaining term in excess of 12 months).

amortization of, a Subsidiary of Bucyrus shall be added to Consolidated Net
Income to compute EBITDA only to the extent (and in the same proportion) that
the net income of such Subsidiary was included in calculating Consolidated Net
Income and only if a corresponding amount would be permitted at the date of

REGISTRATION RIGHTS

24, 1997 (the "Registration Agreement"), pursuant to which Issuers agree, for
the benefit of the holders of the Existing Notes, at the Issuers' cost, to (i)
file a registration statement (the "Exchange Offer Registration Statement")
within 60 days after the Issue Date with the Commission with respect to a
registered offer to exchange the Existing Notes for the Exchange Notes that will
be issued under the Indenture in the same aggregate principal amount as and with
terms that will be identical in all respects to the Existing Notes (except that
the Exchange Notes will not contain terms with respect to the liquidated damages
provision and transfer restrictions); (ii) use their best efforts to cause the
Exchange Offer Registration Statement to be declared effective under the
Securities Act within 150 days after the Issue Date; and (iii) use their best
efforts to consummate the Exchange Offer within 180 days after the Issue Date.
Promptly after the Exchange Offer Registration Statement being declared
effective, the Issuers will offer the Exchange Notes in exchange for surrender
of the Notes (the "Exchange Offer"). The Issuers will keep the Exchange Offer
open for not less than 30 days (or longer if required by applicable law) after
the date notice of the Exchange Offer is mailed to the Noteholders. For each
Existing Note tendered to the Issuers pursuant to the Exchange Offer and not
validly withdrawn by the holder thereof, the holder of such Existing Note will
receive an Exchange Note having a principal amount equal to the principal amount
of such surrendered Existing Note.
 
     Based on existing interpretations of the Securities Act by the staff of the
Commission set forth in several no-action letters to third parties, and subject
to the immediately following sentence, the Issuers believe that the Exchange
Notes issued pursuant to the Exchange Offer may be offered for resale, resold
and otherwise transferred by the holders thereof without further compliance with
the registration and prospectus delivery provisions of the Securities Act.
However, any purchaser of Existing Notes who is an "affiliate" (within the
meaning of the Securities Act) of any of the Issuers or who intends to
participate in the Exchange Offer for the purpose of distributing the Exchange
Notes, a broker-dealer (within the meaning of the Securities Act) that acquired
Existing Notes in a transaction other than as part of its market-making or other
trading activities and who has arranged or has an understanding with any person
to participate in the distribution of the Exchange Notes: (i) will not be able
to rely on the interpretation by the staff of the Commission set forth in the
above-mentioned no-action letters; (ii) will not be able to tender its Existing
Notes in the Exchange Offer; and (iii) must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
sale or transfer of Existing Notes unless such sale or transfer is made pursuant
to an exemption from such requirements.

     Each holder of Existing Notes (other than certain specified holders) who
wishes to exchange Existing Notes for Exchange Notes in the Exchange Offer will
be required to represent that (i) it is not an affiliate of any of the Issuers;
(ii) any Exchange Notes to be received by it were acquired in the ordinary
course of its business; and (iii) at the time of commencement of the Exchange
Offer, it has no arrangement or understanding with any person to participate in
the distribution (within the meaning of the Securities Act) of the Exchange
Notes. In addition, in connection with any resales of Exchange Notes, any
broker-dealer (an "Exchanging Dealer") who acquired Existing Notes for its own
account as a result of market-making activities or other trading activities must
deliver a prospectus meeting the requirements of the Securities Act. The
Commission has taken the position that Exchanging Dealers may fulfill their
prospectus delivery requirements with respect to the Exchange Notes (other than
a resale of an unsold allotment from the original sale of the Existing Notes)
with the prospectus contained in the Exchange Offer Registration Statement.
Under the Registration Agreement, the Issuers are required to allow Exchanging
Dealers to use the prospectus contained in the Exchange Offer Registration
Statement in connection with the resale of such Exchange Notes for a period of
one year following the Issue Date.
 
     In the event that any changes in law or applicable interpretations of the
staff of the Commission do not permit the Issuers to effect the Exchange Offer,
or if for any reason the Exchange Offer Registration Statement is not declared
effective within 150 days following the Issue Date, the Issuers will, in lieu
of, or upon the request of an Initial Purchaser under certain circumstances, in
addition to, effecting the registration of the Exchange Notes pursuant to the
Exchange Offer Registration Statement and at their cost: (i) as promptly as
practicable, file with the Commission a shelf registration statement (the "Shelf
Registration Statement") covering resales of the Existing Notes; (ii) use their
best efforts to cause the Shelf Registration Statement to be declared effective
under the Securities Act by the 180th day after the Issue Date (or promptly in
the event of a request by an Initial Purchaser); and (iii) keep effective the
Shelf Registration Statement until two years after its effective date (or until
one year after its effective date if such Shelf Registration Statement is filed
at the request of an Initial Purchaser). The Issuers will, in the event of the
filing of a Shelf Registration Statement, provide to each holder covered by the
Shelf Registration Statement copies of the prospectus that is a part of the
Shelf Registration Statement, notify each such holder when the Shelf
Registration Statement for the Existing Notes has become effective, and take
certain other actions as are required to permit unrestricted resales of Existing
Notes. A holder that sells such Existing Notes pursuant to the Shelf
Registration Statement generally will be required to be named as a selling
security holder in the related prospectus and to deliver a prospectus to the
purchaser, will be subject to certain of the civil liability provisions under
the Securities Act in connection with such sales and will be bound by the
provisions of the Registration Agreement that are applicable to such holder
(including certain indemnification obligations). In addition, each holder will
be required to deliver information to be used in connection with the Shelf
Registration Statement and to benefit from the provisions regarding Special
Interest set forth in the following paragraph.
 
     If (i) within 60 days after the Issue Date, neither the Exchange Offer
Registration Statement nor the Shelf Registration Statement has been filed with
the Commission; (ii) within 150 days after the Issue Date, the Exchange Offer
Registration Statement has not been declared effective; (iii) within 180 days
after the Issue Date, neither the Exchange Offer has been consummated nor the
Shelf Registration Statement has been declared effective; or (iv) after either
the Exchange Offer Registration Statement or the Shelf Registration Statement
has been declared effective, such Registration Statement thereafter ceases to be
effective or usable (subject to certain exceptions) in connection with resales
of Existing Notes or Exchange Notes in accordance with and during the periods
specified in the Registration Agreement (each such event referred to in clauses
(i) through (iv), a "Registration Default"), liquidated damages ("Liquidated
Damages") will accrue on the Existing Notes and the Exchange Notes from and
including the date on which any such Registration Default shall occur to but
excluding the date on which all Registration Defaults have been cured.
Liquidated Damages will accrue at a rate of $0.05 per week per $1,000 principal
amount of the Existing Notes during the 90-day period immediately following the
occurrence of any Registration Default and shall increase $0.05 per
 
                                       101
<PAGE>   108
 
week per $1,000 principal amount of the Existing Notes at the end of each
subsequent 90-day period, but in no event shall such Liquidated Damages exceed
$0.25 per week per $1,000 principal amount of Existing Notes.
 
     The summary herein of certain provisions of the Registration Agreement does
not purport to be complete and is subject to, and is qualified in its entirety
by reference to, all the provisions of the Registration Agreement, a copy of
which is available upon request to Bucyrus as provided under "Available
Information."
 
CERTAIN FEDERAL TAX CONSIDERATIONS
 
     Following is a general discussion of the principal United States federal
income tax consequences of the purchase, ownership and disposition of the Notes
to initial investors who are United States holders (that is, a holder that is,
for United States federal income tax purposes, (i) a citizen or resident of the
United States; (ii) a corporation, partnership or other entity created or
organized in or under the laws of the United States or of any political
subdivision thereof; (iii) an estate the income of which is subject to United
States federal income taxation regardless of its source; (iv) a trust if (X) a
U.S. court is able to exercise primary supervision over the administration of
the trust, and (Y) one or more U.S. persons have the authority to control all
substantial decisions of the trust; or (v) any other person whose income or gain
in respect of a Note is effectively connected with the conduct of a U.S. trade
or business).
 
     This discussion is based on currently existing provisions of the Internal
Revenue Code of 1986, as amended, existing and proposed U.S. Treasury
regulations promulgated thereunder, and administrative and judicial
interpretations thereof, all as in effect or proposed on the date hereof and all
of which are subject to change, possibly with retroactive effect, or different
interpretations (the "Code"). This discussion does not address the tax
consequences to subsequent purchasers of Notes, and is limited to investors who
hold the Notes as capital assets. Moreover, the discussion is for general
information only, and does not address all of the tax consequences that may be
relevant to particular investors in light of their personal circumstances, or to
certain types of investors (such as certain financial institutions, insurance
companies, tax exempt entities, dealers in securities or foreign currencies or
persons who hold the Notes as a position in a straddle or as part of a
"conversion transaction" or who have hedged the interest rate on the Notes).
 
     In general, interest paid or payable on a Note will be taxable to a United
States holder as ordinary interest income at the time it is received or accrued,
in accordance with such holder's method of accounting for federal income tax
purposes. In addition, under certain circumstances the Code may require that a
holder accrue and include as ordinary (interest) income each year a portion of
any "original issue discount" attributable to the Note in advance of the cash
payments attributable to such income, regardless of such holder's regular method
of tax accounting. Assuming that the original issue discount on the Note is not
greater than or equal to a de minimis amount (equal to 0.25% of its stated
principal amount multiplied by the number of complete years to its maturity),
any such original issue discount will be deemed to be zero, and a holder will
not be required to accrue a portion of such discount as income in each taxable
year.
 
     Holders of so-called "contingent payment debt instruments" are required to
accrue all payments thereon (including de minimis original issue discount and
projected contingent payments) on a constant yield basis, to treat gain
recognized on the disposition of the debt instrument as interest income and in
certain circumstances to include market discount in income sooner than otherwise
required. It is not clear under applicable Regulations whether the Liquidated
Damages payable on the Notes in certain circumstances described above under
"Registration Rights" would result in the Notes being treated as contingent
payment debt instruments. The Regulations provide that a payment under a debt
instrument that is payable on the occurrence of a remote or incidental
contingency will not be treated as a contingent payment, but the Regulations do
not provide definitive guidance on whether a contingency such as that which
governs the payment of the Liquidated Damages under the Notes will be regarded
as remote or incidental. Investors should
 
                                       102
<PAGE>   109
 
consult their tax advisors as to the tax considerations relating to the
Liquidated Damages and the possibility that the Notes may be characterized as
contingent payment debt instruments under the Regulations.
 
     Upon the sale, exchange, redemption, retirement at maturity or other
disposition of a Note, a United States holder will generally recognize taxable
gain or loss equal to the difference between the sum of the cash plus the fair
market value of all other property received on such disposition and such
holder's adjusted tax basis in the Note (except to the extent such cash or
property is attributable to accrued interest, which will be taxable as ordinary
income).
 
     In the case of Notes held as capital assets, gain or loss recognized on the
disposition of a Note generally will be capital gain or loss (except to the
extent the gain is attributable to accrued market discount, as described below)
and will be long-term capital gain or loss subject to a maximum rate of 20%, in
the case of individuals, if, at the time of such disposition, the United States
holder's holding period for the Note is more than 18 months. In addition, an
individual will be taxed on his or her net capital gain at a maximum rate of (i)
28%, for property held for 18 months or less but more than one year, and (ii)
18%, for property (X) acquired after December 31, 2000 and (Y) held for more
than five years. Special rules (and generally lower maximum rates) apply for
individuals in lower tax brackets. However, if under the Regulations the Notes
are treated as contingent payment debt instruments, as discussed above, then any
gain realized on such sale, exchange, redemption or retirement will be taxable
as ordinary (interest) income, while any loss realized will be an ordinary loss
to the extent of any amounts previously treated as ordinary (interest) income
under the Regulations.
 
     The exchange of an Existing Note for an Exchange Note should not constitute
a taxable exchange of the Existing Note if the interest rate on the Exchange
Note is equal to the interest rate on the Existing Note. Although there is no
definitive guidance on the issue, even if the interest rate on the Exchange Note
is not equal to the interest rate on the Existing Note because Liquidated
Damages are payable on the Existing Note but not on the Exchange Note, the
exchange should not constitute a taxable exchange of the Existing Note.
 
     An investor who acquires a Note at a cost in excess of its principal amount
will be considered to have purchased the Note at a premium, and may make an
election, applicable to all Notes held by such holder, to amortize such premium,
using a constant yield method, over the remaining term of the Note (or, if a
smaller amortization allowance would result, by computing such allowance with
reference to the amount payable on an earlier call date, and by amortizing such
allowances over the shorter period to such call date).
 
     Although the market discount provisions of the Code generally do not apply
to initial investors in Notes, those provisions may apply to initial investors
who acquire Notes for an amount less than the issue price of the Notes.
Generally, these rules require the holder of a "market discount bond" (as
defined in the Code) to treat any gain realized upon its disposition as interest
income to the extent of the market discount that accrued during the period such
holder held it. A holder may also be required to recognize as ordinary income
any principal payments with respect to a Note to the extent such payments do not
exceed the accrued market discount on the Note. For these purposes, market
discount generally equals the excess (if any) of the stated redemption price of
the Note at its maturity over the basis of the Note in the hands of the holder
immediately after its acquisition. However, market discount is deemed not to
exist if the market discount is less than a statutorily defined de minimis
amount equal to 0.25% of the Note's contract redemption price at maturity
multiplied by the number of complete years to the Note's maturity after the
holder acquired the Note.
 
     The market discount rules also provide that any holder of Notes that were
acquired at a market discount may be required to defer the deduction of a
portion of the interest expense on any indebtedness incurred or maintained to
acquire or carry the Notes, until the Notes are disposed of. A holder of a Note
acquired at market discount may elect to include market discount in income as
the discount accrues. In such a case, the foregoing rules with respect to the
recognition of ordinary
 
                                       103
<PAGE>   110
 
income on dispositions and with respect to the deferral of interest deductions
on indebtedness related to such Note would not apply.
 
     PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
PARTICULAR TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP AND DISPOSITION
OF THE NOTES, INCLUDING THE APPLICABILITY OF ANY FEDERAL ESTATE OR GIFT TAX LAWS
OR ANY STATE, LOCAL OR FOREIGN TAX LAWS, ANY CHANGES IN APPLICABLE TAX LAWS AND
ANY PENDING OR PROPOSED LEGISLATION OR REGULATIONS. IN ADDITION, INDIVIDUAL
NOTEHOLDERS WHO ARE NOT CITIZENS OF THE UNITED STATES SHOULD CONSULT THEIR TAX
ADVISORS AS TO WHETHER THEY WILL OR WILL NOT BE DEEMED TO BE "RESIDENTS" OF THE
UNITED STATES FOR PURPOSES OF THE CODE.

                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives Exchange Notes for its own account
pursuant to the Exchange Offer in exchange for Existing Notes, where such
Existing Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities, must acknowledge and agree that it will
deliver a prospectus in connection with any resale of such Exchange Notes. This
Prospectus, as it may be amended or supplemented from time to time, may be used
for a period of one year after the Expiration Date by a broker-dealer in
connection with resales of Exchange Notes received in exchange for Existing
Notes where such Existing Notes were acquired as a result of market-making
activities or other trading activities. The Company has agreed that, starting on
the Expiration Date and ending on the close of business one year after the
Expiration Date, it will make this Prospectus, as amended or supplemented,
available to any broker-dealer for use in connection with any such resale.
 
     The Company will not receive any proceeds from any sale of Exchange Notes
by broker-dealers. Exchange Notes received by broker-dealers for their own
account pursuant to the Exchange Offer may be sold from time to time in one or
more transactions in the over-the-counter market, in negotiated transactions,
through the writing of options on the Exchange Notes or a combination of such
methods of resale, at market prices prevailing at the time of resale, at prices
related to such prevailing market prices or negotiated prices. Any such resale
may be made directly to purchasers or to or through broker-dealers who may
receive compensation in the form of commissions or concessions from any such
broker-dealer and/or the purchasers of any such Exchange Notes. Any
broker-dealer that resells Exchange Notes that were received by it for its own
account pursuant to the Exchange Offer and any person that participates in the
distribution of such Exchange Notes may be deemed to be an "underwriter" within
the meaning of the Securities Act, and any profit on any such resale of Exchange
Notes and any commissions or concessions received by any such persons may be
deemed to be underwriting compensation under the Securities Act. The Letter of
Transmittal states that by acknowledging and agreeing that it will deliver and
by delivering this Prospectus, a broker-dealer will not be deemed to admit that
it is an "underwriter" within the meaning of the Securities Act.
 
     For a period of 180 days after the Expiration Date, the Company will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal. The Company has agreed to pay all expenses
incident to the Exchange Offer other than commissions or concessions of any
brokers or dealers and will indemnify the holders of the Notes (including any
broker-dealers) against certain liabilities, including liabilities under the
Securities Act.
 
     By acceptance of this Exchange Offer, each broker-dealer agrees that, upon
receipt of notice from the Company of the happening of any event which makes any
statement in the Prospectus untrue in any material respect or which requires the
making of any changes in the Prospectus in order to make the statements therein
not misleading, such broker-dealer will suspend use of the Prospectus until (i)
the Company has amended or supplemented the Prospectus to correct such
misstatement or omission and (ii) either the Company has furnished copies of the
amended or supplemented Prospectus to such broker-dealer or, if the Company has
not otherwise agreed to furnish such copies and declines to do so after such
broker-dealer so requests, such broker-dealer has obtained a copy of such
amended or supplemented Prospectus as filed with the Commission. The Company has
agreed to deliver such notice and such amended or supplemented Prospectus
promptly to any Participating Broker-Dealer that has so notified the Company.
 
     Pursuant to the Registration Agreement, the Company and the Guarantors have
jointly and severally agreed to indemnify the Initial Purchasers against certain
liabilities, including certain liabilities incurred in connection with the
offering of the Existing Notes, and contribute to payments the Initial
Purchasers may be required to make in respect thereof.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To the Board of Directors and
Shareholders of Bucyrus International, Inc.:
 
     We have audited the accompanying balance sheets of Bucyrus International,
Inc. (Delaware Corporation) as of December 31, 1996 and 1995 and the related
statements of operations, common shareholders' investment and cash flows for the
years then ended. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Bucyrus International, Inc.
as of December 31, 1996 and 1995, and the results of its operations and its cash
flows for the years then ended in conformity with generally accepted accounting
principles.

INDEPENDENT AUDITORS' REPORT
 
To the Board of Directors and Shareholders of
Bucyrus International, Inc.:
 
     We have audited the accompanying consolidated statements of operations,
common shareholders' investment (deficiency in assets) and cash flows of Bucyrus
International, Inc. (formerly Bucyrus-Erie Company) and subsidiaries (the
"Company") for the period from December 14, 1994 to December 31, 1994 and the
period from January 1, 1994 to December 13, 1994 (Predecessor Company
operations). These financial statements are the responsibility of Company
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     As discussed in Note B to the consolidated financial statements, on
December 1, 1994, the Bankruptcy Court entered an order confirming an Amended
Joint Plan of Reorganization which became effective on December 14, 1994.
Accordingly, the accompanying consolidated financial statements have been
prepared in conformity with AICPA Statement of Position 90-7, "Financial
Reporting by Entities in Reorganization Under the Bankruptcy Code," for the
Company as a new entity with assets, liabilities, and a capital structure having
carrying values not comparable with prior periods as discussed in Note B to the
consolidated financial statements. Under the Amended Joint Plan of
Reorganization, the Company's parent, B-E Holdings, Inc., was merged with and
into the Company as of the effective date. The consolidated financial statements
for the period prior to December 14, 1994 includes the operating results of the
merged entities (Predecessor Company).
 
     In our opinion, the Company's consolidated financial statements present
fairly, in all material respects, the results of operations and cash flows of
Bucyrus International, Inc. and subsidiaries for the period December 14, 1994 to
December 31, 1994 in conformity with generally accepted accounting principles.
Further, in our opinion, the Predecessor Company consolidated financial
statements referred to above present fairly, in all material respects, the
results of operations and cash flows of the Predecessor Company for the period
January 1, 1994 to December 13, 1994 in conformity with generally accepted
accounting principles.

SUPPLEMENTAL SCHEDULE OF NON-CASH INVESTING AND FINANCING ACTIVITIES
 
(A) On June 27, 1995, the Company issued 64,157 shares of common stock as
    payment in full of $361 of liabilities for certain legal and professional
    fees incurred in connection with the Company's reorganization under Chapter
    11 of the Bankruptcy Code.
 
(B) In 1994, the Predecessor Company increased the carrying amount of the Series

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE A -- SUMMARY OF ACCOUNTING POLICIES
 
NATURE OF OPERATIONS
 
     Bucyrus International, Inc. (the "Company"), formerly known as Bucyrus-Erie
Company, is a Delaware corporation and a leading manufacturer of surface mining
equipment, principally walking draglines, electric mining shovels and blast hole
drills, and related replacement parts. Major markets for the surface mining
industry are coal mining, copper and iron ore mining and phosphate production.
 
BASIS OF PRESENTATION
 
     As discussed in Note B, the Company accounted for the reorganization under
Chapter 11 of the Bankruptcy Code effective December 14, 1994 (the "Effective
Date") 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" ("SOP 90-7"). Accordingly, the consolidated financial
statements of the Company are not comparable to the consolidated financial
statements of periods prior to the Effective Date. The Predecessor Company
consolidated financial statements are those of B-E Holdings, Inc. ("Holdings"),
the former parent of the Company, which include the accounts and operating
results of the Company.
 
     The preparation of the consolidated financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities and the reported amounts of
revenues and expenses. Actual results could differ from those estimates.
 
PRINCIPLES OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of all
subsidiaries. All significant intercompany transactions, profits and accounts
have been eliminated.
 
CASH EQUIVALENTS
 
     All highly liquid investments with maturities of three months or less when
purchased are considered to be cash equivalents. The carrying amount of these
investments approximates fair value.
 
RESTRICTED FUNDS ON DEPOSIT
 
     Restricted funds on deposit represent cash and temporary investments used
to support the issuance of standby letters of credit and other obligations. The
carrying amount of these funds approximates fair value.
 
INVENTORIES
 
     Inventories are stated at lower of cost (first-in, first-out method) or
market (replacement cost or estimated net realizable value). Advances from
customers are netted against inventories to the extent of related accumulated
costs. Advances in excess of related costs and earnings on uncompleted contracts
are classified as a liability to customers.
 
INTANGIBLES
 
     As of the Effective Date, intangible assets were recorded at estimated fair
value to the extent of available reorganization value and accumulated
amortization was eliminated in accordance with the
 
                                       F-9

                  BUCYRUS INTERNATIONAL, INC. AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
principles of fresh start reporting. Intangible assets consist of engineering
drawings and bill-of-material listings which are being amortized on a
straight-line basis over 20 years (30 years for the Predecessor Company). At
December 31, 1996 and 1995, accumulated amortization for intangible assets was
$975,000 and $499,000, respectively.
 
PROPERTY, PLANT AND EQUIPMENT
 
     As of the Effective Date, property, plant and equipment was recorded at
estimated fair value to the extent of available reorganization value and
accumulated depreciation was eliminated in accordance with the principles of
fresh start reporting. Additions made subsequent to the Effective Date are
recorded at cost. Depreciation is provided over the estimated useful lives of
respective assets using the straight-line method for financial reporting and
accelerated methods for income tax purposes. Estimated useful lives used for
financial reporting purposes range from ten to forty years for buildings and
improvements and three to seventeen years for machinery and equipment.
 
FOREIGN CURRENCY TRANSLATION
 
     The assets and liabilities of foreign subsidiaries are generally translated
into U.S. dollars using year-end exchange rates. Revenues and expenses are
translated at average rates during the year. Adjustments resulting from this
translation, except for one foreign subsidiary which operates in a highly
inflationary economy, are deferred and reflected as a separate component of
Common Shareholders' Investment. For the one subsidiary operating in a highly
inflationary economy, adjustments resulting from the translation of financial
statements are reflected in the Consolidated Statements of Operations.
 
REVENUE RECOGNITION
 
     Revenue from long-term sales contracts is recognized using the
percentage-of-completion method. At the time a loss on a contract becomes known,
the amount of the estimated loss is recognized in the consolidated financial
statements. Included in the current portion of liabilities to customers on
uncompleted contracts and warranties are advances in excess of related costs and
earnings on uncompleted contracts of $575,000 and $790,000 at December 31, 1996
and 1995, respectively.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
     In 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("SFAS 121").
SFAS 121 requires that long-lived assets and certain identifiable intangibles to
be held and used by an entity be reviewed for impairment when certain events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. The Company adopted SFAS 121 in 1996. Upon completion of a
review of all long-lived assets and intangibles, management determined that no

NOTE B -- FINANCIAL REPORTING RELATING TO REORGANIZATION PROCEEDINGS
 
     On February 18, 1994 (the "Petition Date"), Holdings and the Company, which
at such time was a wholly-owned subsidiary of Holdings, commenced voluntary
petitions under Chapter 11 of the Bankruptcy Code and filed a prepackaged joint
plan of reorganization in the United States Bankruptcy Court, Eastern District
of Wisconsin (the "Bankruptcy Court"). No other subsidiaries of Holdings or the
Company were included in the filing. On December 1, 1994, the Bankruptcy Court
entered an order confirming the Second Amended Joint Plan of Reorganization of
Holdings and the Company as modified on December 1, 1994 (the "Amended Plan").
The Amended Plan became effective on December 14, 1994.
 
     On December 14, 1994, Holdings merged with and into the Company pursuant to
the Amended Plan and the Agreement and Plan of Merger dated as of December 14,
1994 between Holdings and the Company (the "Merger Agreement"). Pursuant to the
Amended Plan and the Merger Agreement, the Company issued 10,170,417 shares of
its common stock, par value $.01 per share (the "Common Stock"), which included
10,000,004 shares of Common Stock issued to holders of Holdings' and the
Company's unsecured debt securities and Holdings' equity securities (including
preferred stock) in exchange for such securities. The Company also issued
170,413 shares of Common Stock and paid $350,000 in cash to Bell Helicopter
Textron, Inc. ("Bell Helicopter") in settlement of Bell Helicopter's claims
against the Company and an inactive subsidiary of the Company asserted in a
civil action.
 
     Also on the Effective Date pursuant to the Amended Plan, the Company issued
an aggregate principal amount of $52,072,000 of Secured Notes due December 14,
1999 (the "Secured Notes") in exchange for the outstanding Series A 10.65%
Senior Secured Notes due July 1, 1995 of the Company, the outstanding Series B
16.5% Senior Secured Notes due January 1, 1996 of the Company, the obligations
of the Company under its sale and leaseback financing arrangement and accrued
interest, the sum of said items being $54,571,000.
 
     As a result of these transactions pursuant to the Amended Plan, an
extraordinary gain on debt discharge of $142,480,000 was recognized, which
consists of the following:

Bankruptcy Code. In 1995, reorganization items consist entirely of legal and
professional fees. Reorganization items in 1994 consist of $8,023,000 of legal
and professional fees, $41,122,000 to adjust debt and redeemable preferred stock
to the amount of the allowed claims in the Amended Plan and a $1,113,000
write-off of capitalized financing costs. These expenses were partially offset
by $365,000 of interest income earned from the Petition Date through December
13, 1994 on accumulated cash balances of Holdings and the Company.
 
     The Company accounted for the reorganization by using the principles of
fresh start reporting as required by SOP 90-7. Under the principles of fresh
start reporting, total assets were recorded at their assumed reorganization
value, with the reorganization value allocated to identifiable tangible and
intangible assets on the basis of their estimated fair value, and liabilities
were adjusted to the present values of amounts to be paid where appropriate. The
consolidated financial statements for periods subsequent to the Effective Date
include the related amortization charges associated with the fair value
adjustments.
 
NOTE C -- RESTRUCTURING EXPENSES
 
     Restructuring expenses of $2,577,000 for the year ended December 31, 1995
consist of employee severance expenses recorded to reflect the cost of reduced
employment and the severance costs related to the resignation of three officers
of the Company.
 
NOTE D -- RECEIVABLES
 
     Receivables at December 31, 1996 and 1995 include $6,830,000 and
$6,994,000, respectively, of revenues from long-term contracts which were not
billable at that date. Billings on long-term contracts are made in accordance
with the payment terms as defined in the individual contracts.

     Interest on the Secured Notes accrued at a rate of 10.5% per annum until
December 14, 1995. Thereafter, interest accrues at a rate of 10.5% per annum, if
paid in cash, or 13.0% per annum, if paid in kind. The Credit Agreement (as
defined below) required accrued interest on the Secured Notes to be paid in kind
prior to January 1, 1996, and thereafter restricts the cash payment of principal
and interest on the Secured Notes unless certain ratios and conditions are met.
Otherwise, interest on the Secured Notes is payable in kind at the discretion of
the Company during the term of the Secured Notes. All interest through June 30,
1996 was accrued at 13% since the Company paid this interest in kind. For the
quarter ended September 30, 1996, interest was accrued at 10.5% since at that
time it was the Company's intention to pay the December 31, 1996 interest
payment in cash. During the fourth quarter of 1996, the Company decided to pay
the December 31, 1996 interest payment in kind. As a result, interest expense of
$386,000 related to the third quarter of 1996 was recorded during the fourth
quarter of 1996.
 
     The Secured Notes are secured by a security interest on substantially all
of the Company's property (other than land and buildings), the shares of the
Company's United States subsidiaries and 65% of the shares of certain non-United
States subsidiaries (collectively, the "Pledged Shares"). The Secured Notes are
subordinated to the security interest in favor of Bank One,

Milwaukee, National Association ("Bank One") up to $16,000,000 in indebtedness
and other amounts owing under the Credit Agreement (as defined below).
 
     During 1996, there were two trades of the Secured Notes, which are
privately held. In February, 1996, 97.2% of the Secured Notes were purportedly
sold for 94.67% of face value. In March, 1996, the remaining 2.8% of the Secured
Notes were purportedly sold for 98% of face value. Based on these trades,
management believes that the carrying value of the Secured Notes approximates
fair value.
 
     The Construction Loan outstanding at Bucyrus Chile, Ltda. at December 31,
1996 bears interest at 9.24% and is due in February, 1997. However, this loan
will be refinanced with a new $2,000,000 construction loan which will be payable
commencing in 1999. Therefore, the amount outstanding at December 31, 1996 is
classified as long-term debt and the maturities below reflect the refinancing.
 
     Maturities of long-term debt are the following for each of the next five
years:

     The Company has a Credit Agreement dated as of December 14, 1994 (the
"Credit Agreement"), with Bank One. The Credit Agreement, as amended, contains a
credit facility for working capital and general corporate purposes (the "Loan
Facility"), a letter of credit facility (the "L/C Facility") and a project
financing loan facility (the "Project Financing Facility"). Under the Loan
Facility, the Company may borrow up to $2,500,000, provided that it meets
certain earnings before interest, taxes, depreciation and amortization tests, as
defined. Borrowings under the Loan Facility mature on April 30, 1998 and
interest is payable at the Company's option either at a rate equal to Bank One's
reference rate plus 0.75% per annum or an adjusted LIBOR rate plus 2.75% per
annum. Under the L/C Facility, Bank One has agreed to issue letters of credit
through April 30, 1998 in an aggregate amount not in excess of $15,000,000 minus
the then outstanding aggregate borrowings by the Company under the Loan
Facility, provided that no letter of credit may expire after April 30, 1999.
Under the Project Financing Facility, Bank One may make project financing loans
to the Company from time to time. Borrowings under the Project Financing
Facility bear interest at the Company's option either at a rate equal to Bank
One's reference rate or an adjusted LIBOR rate plus a variable margin.
Borrowings under the Credit Agreement are secured by a security interest on
substantially all of the Company's property (other than land and buildings),
including the Pledged Shares. At December 31, 1996 and 1995, the Company had
borrowings outstanding under the Loan Facility of $357,000 and $269,000,
respectively. At December 31, 1996 and 1995, $7,316,000 and $3,419,000,
respectively, of the L/C Facility was being used. Under the Project Financing
Facility, the Company has a line of credit for $14,000,000 to support one
current order. Bank One has participated a portion of the Project Financing
Facility to The Bank of Nova Scotia. Availability is based on the amount of
inventory being financed and any accounts receivable relating to such project.
Availability at December 31, 1996 was approximately $3,300,000. There were no
borrowings under the Project Financing Facility at December 31, 1996 and 1995.
 
     The Credit Agreement prohibits the Company from making any dividends or
other distributions upon the Common Stock, other than dividends payable solely
in Common Stock or other equity securities of the Company. The Indenture
relating to the Secured Notes prohibits the Company from declaring or paying any
dividend or making any distribution in respect of the Common Stock (other than
dividends or distributions payable solely in shares of Common Stock or in
options, warrants or

     The agreements relating to the Secured Notes and the Credit Agreement
permit additional project financing from other lenders to manufacture mining
machinery or other products pursuant to binding purchase contracts. Project
financing borrowings are secured by the inventory being financed and any
accounts receivable relating to such project. Project financing borrowings
mature not later than the date of the final payment by the customer under the
applicable purchase contract. At December 31, 1996 and 1995, the Company had
$2,431,000 and $5,132,000, respectively, of outstanding project financing
borrowings not related to the Project Financing Facility. The outstanding
project financing borrowings at December 31, 1996 and 1995 bear interest at
8.25% and 7.75%, respectively, and are included in Short-Term Obligations in the
Consolidated Balance Sheets.
 
     As required under various agreements, Equipment Assurance Limited, an
off-shore insurance subsidiary of the Company, has pledged $1,056,000 and
$2,856,000 of its cash to secure its reimbursement obligations for outstanding
letters of credit at December 31, 1996 and 1995, respectively. Bucyrus Chile
Ltda. has pledged $23,000 and $21,000 of its cash for a bank guarantee at
December 31, 1996 and 1995, respectively. These collateral amounts are
classified as Restricted Funds on Deposit in the Consolidated Balance Sheets.
 
NOTE H -- COMMON SHAREHOLDERS' INVESTMENT
 
     In 1995, the Company's Board of Directors adopted the Bucyrus
International, Inc. Non-Employee Directors' Stock Option Plan (the "Directors'
Stock Option Plan"). The Directors' Stock Option Plan provides for the automatic
grant of non-qualified stock options to non-employee members of the Board of
Directors for up to 60,000 shares of Common Stock at an exercise price based on
the last sale price of the Common Stock on the date of grant. Options granted
vest and are exercisable immediately on the date of grant and terminate on the
earlier of ten years after the date of grant, six months after the non-employee
director ceases to be a director of the Company by reason of death, or three
months after the non-employee director ceases to be a director of the Company
for any reason other than death. The following summary shows activity and
outstanding balances of options exercisable for shares of Common Stock under the
Directors' Stock Option Plan:

     Due to the recent history of net operating losses, a valuation allowance
has been used to reduce the net deferred tax assets (after giving effect to
deferred tax liabilities) for domestic operations to an amount that is more
likely than not to be realized. For the year ended December 31, 1996, the
valuation allowance was increased by $388,000 to offset an increase in net
deferred tax assets for which no tax benefit was recognized.
 
     Because the consummation of the Amended Plan on the Effective Date resulted
in an "ownership change" within the meaning of Section 382 of the Internal
Revenue Code, the net operating loss carryforwards ("NOL") available to the
Company as of the Effective Date were limited to $53,460,000, the annual use of
which is limited to $3,564,000 plus any unused annual NOL limitation amounts
from years subsequent to the Effective Date. NOL incurred subsequent to the
Effective Date is not subject to the annual Section 382 limitation. At December
31, 1996, the Company has available approximately $69,109,000 of federal NOL,
expiring in years 2003 through 2011, to offset against future taxable income.
The total federal NOL available for 1997, including the 1997 annual NOL
limitation amount, is approximately $26,341,000.
 
     Additionally, the Company has available for federal income tax purposes
approximately $479,000 of alternative minimum tax credit carryforward which
carries forward indefinitely. However, because the credit arose prior to the
Effective Date, it will be subject to the annual limitations discussed above and
will not be usable until the year 2010.
 
     The Company also has a significant amount of state NOL's (which expire in
the years 1997 through 2011) available to offset future state taxable income in
states where it has significant operations. Since the majority of states in
which the Company files its state returns follow rules similar to federal rules,
it is expected that the usage of state NOL's will be limited to approximately
$61,000,000.
 
     Cumulative undistributed earnings of foreign subsidiaries that are
considered to be permanently reinvested, and on which U.S. income taxes have not
been provided by the Company, amounted to approximately $19,000,000 at December
31, 1996. It is not practicable to estimate the amount of

additional tax which would be payable upon repatriation of such earnings;
however, due to foreign tax credit limitations, higher effective U.S. income tax
rates and foreign withholding taxes, additional taxes could be incurred.
 
NOTE J -- PENSION AND RETIREMENT PLANS
 
     The Company has several pension and retirement plans covering substantially
all employees. The plan covering domestic salaried and certain non-union hourly
employees provides pension benefits that are based on final average pay
formulas. The funding policy for that plan is to contribute amounts at least
equal to the minimum annual amount required by applicable regulations. Plans
covering hourly and certain union members generally provide benefits of stated
amounts for each year of service. Contributions to these plans are funded based
on normal cost plus amortization of unfunded past service cost over 30 to 40
years. In addition, the Company has certain unfunded supplemental retirement
plans for which benefits are payable out of the general funds of the Company.
 
     The following tables set forth the domestic plans' funded status and
amounts recognized in the consolidated financial statements at December 31, 1996
and 1995:

     The weighted average discount rate, rate of increase in future compensation
levels, and expected long-term rate of return on assets used to develop the
projected benefit obligation at December 31, 1996 were 7.5%, 4.5% and 9%,
respectively. The corresponding rates used at December 31, 1995 were 7.75%, 5%
and 9%, respectively. Mortality assumptions were also updated in 1996. The
changes in the various assumptions resulted in a $6,581,000 increase in the
projected benefit obligation.

7.75%, respectively. The decrease in the discount rate resulted in a $271,000
increase in the accumulated postretirement benefit obligation. The assumed
health care cost trend rate used in measuring the accumulated postretirement
benefit obligation was 10% at December 31, 1996, declining 1% each year
thereafter, to 5% in the year 2002 and beyond. A 1% increase in the assumed
health care cost trend rate for each year would increase the accumulated
postretirement benefit obligation at December 31, 1996 by $972,000 and would
increase the net periodic postretirement benefit cost for 1996 by $109,000.
 
NOTE L -- RESEARCH AND DEVELOPMENT
 
     Expenditures for design and development of new products and improvements of
existing mining machinery products, including overhead, aggregated $6,930,000 in
1996, $5,739,000 in 1995 and $4,181,000 (including $3,945,000 for the
Predecessor Company) in 1994. All engineering and product development costs are
charged to product development expense as incurred.
 
NOTE M -- CALCULATION OF NET EARNINGS (LOSS) PER SHARE OF COMMON STOCK
 
     1996 net earnings per share of common stock is based on the weighted
average number of common and common equivalent shares outstanding during the
year. Restricted common stock (see Note H) is considered to be issued and
outstanding and is included in the net earnings per share calculation using the
treasury stock method. Previous years' net earnings (loss) per share of common
stock are based on the weighted average number of common shares outstanding
since common stock equivalents were not significant. Stock options outstanding
in 1994 under the B-E Holdings, Inc. 1988 Stock Option Plan were not included in
the per share calculations because they were anti-dilutive. The weighted average
number of common and common equivalent shares outstanding for the years ended
December 31, 1996 and 1995, the period December 14, 1994 to December 31, 1994
and the period January 1, 1994 to December 13, 1994, were 10,258,604,
10,203,462, 10,170,417 and 9,268,627, respectively.
 
     Net earnings attributable to common shareholders for the Predecessor

     Financial information by geographical area is summarized in the following
table. Each geographic area represents the origin of the financial information
presented. Transfers between geographic areas represent intercompany export
sales of goods produced in the United States and are accounted for based on
established sales prices between the related companies. In computing operating
earnings for non-United States subsidiaries, no allocations of interest or
income taxes have been made. Eliminations for operating earnings (loss) include
elimination of general corporate expenses. Identifiable assets of subsidiaries
are those related to the operations of those subsidiaries. United States assets
consist of all other operating assets.

     Export sales from United States operations, excluding sales to affiliates,
amounted to $103,777,000 in 1996, $69,476,000 in 1995 and $60,627,000 (including
$57,898,000 for the Predecessor Company) in 1994.
 
     In 1996, one customer received approximately 14% of the Company's
consolidated net sales. In 1995 and 1994, a different customer received
approximately 22% and 20%, respectively, of the Company's consolidated net
sales. The Company is not dependent upon any one customer.
 
NOTE O -- COMMITMENTS, CONTINGENCIES AND CREDIT RISKS
 
     Jackson National Life Insurance Company ("JNL"), the holder of
approximately 40.14% of the outstanding Common Stock and 97.2% of the Secured
Notes, has filed a claim (the "JNL 503(b) Claim") against the Company for
reimbursement of approximately $3,300,000 of professional fees and disbursements
incurred in connection with the Company's Chapter 11 proceedings pursuant to
Section 503(b) of the Bankruptcy Code. Pursuant to a settlement agreement dated
May 23, 1995,

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
JNL agreed that, in the event that the JNL 503(b) Claim is allowed in whole or
in part by the Bankruptcy Court, in lieu of requiring payment of any award in
cash, JNL will accept payment in Common Stock at a price equal to $5.6375 per
share. By order dated June 3, 1996, the Bankruptcy Court ruled that JNL would be
awarded the sum of $500. JNL has appealed the decision. The Company has been
advised by its reorganization counsel that in said counsel's opinion the JNL
503(b) Claim is without merit; however, the ultimate outcome of this matter
cannot presently be determined. Accordingly, no provision for any loss that may
result upon resolution of this matter has been made in the consolidated
financial statements.
 
     Concurrently with the trial of the JNL 503(b) Claim, the Bankruptcy Court
considered the final fee application of the law firm of Milbank, Tweed, Hadley &
McCloy ("Milbank"), who rendered services as reorganization counsel for the
Company in connection with the Chapter 11 proceedings. The Milbank fee
application was for approximately $2,330,000, of which 80% had previously been
paid by the Company on an interim basis. By order dated June 3, 1996, the
Bankruptcy Court ruled that Milbank would receive 80% of the claimed amount as
full and final compensation, thereby resulting in no further payments being due
and owing to Milbank on the claim. JNL appealed the decision of the Bankruptcy
Court not to order disgorgement of amounts already paid to Milbank. Milbank has
not appealed the decision.
 
     The Company's wholly-owned subsidiary, Boonville Mining Services, Inc.
("BMSI"), was a defendant in an amended complaint filed on September 24, 1992 by
Dresser Industries, Inc. and Global Industrial Technologies, Inc. (the
"Plaintiffs"), alleging that BMSI's purchase of drawings and other assets of C&M
of Indiana, a division of Construction and Mining Services, Inc., and BMSI's use
of these and other drawings allegedly acquired subsequently, constituted a
misappropriation of the Plaintiffs' trade secrets relating to Marion Power
Shovel Company, a division of Global Industrial Technologies, Inc. BMSI had
denied these claims. On June 17, 1996, BMSI settled the litigation which
resulted in an immaterial effect on earnings.
 
     The Company is involved in various other litigation arising in the normal
course of business. It is the view of management that the Company's recovery or
liability, if any, under pending litigation is not expected to have a material
effect on the Company's financial position or results of operations, although no
assurance to that effect can be given.
 
     Expenditures for ongoing compliance with environmental regulations that
relate to current operations are expensed or capitalized as appropriate.
Expenditures that relate to an existing condition caused by past operations and
which do not contribute to current or future revenue generation are expensed.
Liabilities are recorded when environmental assessments indicate that remedial
efforts are probable and the costs can be reasonably estimated. Estimates of the
liability are based upon currently available facts, existing technology and
presently enacted laws and regulations. These liabilities are included in the
Consolidated Balance Sheets at their undiscounted amounts. Recoveries are
evaluated separately from the liability and, if appropriate, are recorded
separately from the associated liability in the Consolidated Balance Sheets.
 
     The Company is normally subject to numerous product liability claims, many
of which relate to products no longer manufactured by the Company or its
subsidiaries, and other claims arising in the ordinary course of business. The
Company has insurance covering most of said claims, subject to varying
deductibles ranging from $0.3 million to $3.0 million, and has various limits of
liability depending on the insurance policy year in question. It is the view of
management that the final resolution of said claims and other similar claims
which are likely to arise in the future will not individually or in the
aggregate have a material effect on the Company's financial position or results
of operations, although no assurance to that effect can be given.
 
     The Company has obligations under various operating leases and rental and
service agreements. The expense relating to these agreements was $5,658,000 in
1996, $5,351,000 in 1995 and

     At December 31, 1996, the Company is also committed to acquire
approximately $1,550,000 of equipment. The Company expects to lease the
equipment.
 
     A significant portion of the Company's consolidated net sales are to
customers whose activities are related to the coal, copper and iron ore mining
industries, including some who are located in foreign countries. The Company
generally extends credit to these customers and, therefore, collection of
receivables may be affected by the mining industry economy and the economic
conditions in the countries where the customers are located. However, the
Company closely monitors extension of credit and has not experienced significant
credit losses. Also, most foreign sales are made to large, well-established
companies. The Company generally requires collateral or guarantees on foreign
sales to smaller companies.

NOTE Q -- SUPPLEMENTAL CONSOLIDATING CONDENSED FINANCIAL INFORMATION
 
     The Company's payment obligations under the proposed Notes are to be
guaranteed by certain of the Company's wholly-owned subsidiaries (the "Guarantor
Subsidiaries"). Such guarantees are full, unconditional and joint and several.
Separate financial statements of the Guarantor Subsidiaries are not presented
because the Company's management has determined that they would not be material
to investors. The following supplemental financial information sets forth, on an
unconsolidated basis, statement of operations, balance sheet, and statement of
cash flow information for the Company ("Parent Company"), for the Guarantor
Subsidiaries and for the Company's non-guarantor subsidiaries (the "Other
Subsidiaries"). The supplemental financial information reflects the investments
of the Company in the Guarantor and Other Subsidiaries using the equity method
of accounting. Parent Company amounts for net earnings and common shareholders'
investment differ from consolidated amounts as intercompany profit in subsidiary
inventory has not been eliminated in the Parent Company statement but has been
eliminated in the Consolidated Totals.

   financial results for the interim periods. Certain items are included in
   these statements based on estimates for the entire year.

   interim consolidated condensed financial statements. Therefore, these
   statements should be read in conjunction with the Company's 1996 annual
   report on Form 10-K filed with the Securities and Exchange Commission on
   March 20, 1997.

4. Net earnings per share of common stock for the six months ended June 30, 1997
   is based on the weighted average number of common and common equivalent
   shares outstanding during the period. Restricted common stock is considered
   to be issued and outstanding and is included in the net earnings per share
   calculation using the treasury stock method. Net earnings per share of common
   stock for the six months ended June 30, 1996 is based on the weighted average
   number of common shares outstanding since common stock equivalents were not
   significant.
 
  The Financial Accounting Standards Board has issued Statement of Financial
  Accounting Standards No. 128, "Earnings Per Share". The Company will adopt
  this statement for the year ending December 31, 1997 and will restate prior
  period earnings per share as required. Adoption of this statement will not
  have an impact on the Company's reported earnings per share for the six months
  ended June 30, 1997 and 1996.
 
5. The Company's payment obligations under the proposed Notes are to be
   guaranteed by certain of the Company's wholly-owned subsidiaries (the
   "Guarantor Subsidiaries"). Such guarantees are full, unconditional and joint
   and several. Separate financial statements of the Guarantor Subsidiaries are
   not presented because the Company's management has determined that they would
   not be material to investors. The following supplemental financial
   information sets forth, on an unconsolidated basis, statement of operations,
   balance sheet, and statement of cash flow information for the Company
   ("Parent Company"), for the Guarantor Subsidiaries and for the Company's
   non-guarantor subsidiaries (the "Other Subsidiaries"). The supplemental
   financial information reflects the investments of the Company in the
   Guarantor and Other Subsidiaries using the equity method of accounting.
   Parent Company amounts for net earnings and common shareholders' investment
   differ from consolidated amounts as intercompany profit in subsidiary
   inventory has not been eliminated in the Parent Company statement but has
   been eliminated in the Consolidated Totals.

     We have audited the accompanying combined balance sheet of the Surface
Mining and Equipment Business of Global Industrial Technologies, Inc. (the

operations, equity and cash flows for the year then ended. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Surface Mining and
Equipment Business of Global Industrial Technologies, Inc., as of October 31,
1996 and the results of its operations and its cash flows for the year then

 SURFACE MINING AND EQUIPMENT BUSINESS OF GLOBAL INDUSTRIAL TECHNOLOGIES, INC.
 
                     NOTES TO COMBINED FINANCIAL STATEMENTS
 
NOTE A -- SUMMARY OF ACCOUNTING POLICIES
 
NATURE OF OPERATIONS
 
     The accompanying combined financial statements include all of the
operations, assets and liabilities of the surface mining and equipment business
(the "Marion Business") of Global Industrial Technologies, Inc. ("Global"). The
Marion Business consists principally of walking draglines and electric mining
shovels and related replacement parts. Major markets for the surface mining
industry are coal mining, copper and iron ore mining and phosphate production.
 
USE OF ESTIMATES
 
     The preparation of the combined financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities,
disclosure of contingent assets and liabilities and the reported amounts of
revenues and expenses. Actual results could differ from those estimates.
 
PRINCIPLES OF COMBINATION AND PRESENTATION
 
     These financial statements combine subsidiaries, branches or divisions of
Global that operate in the surface mining and equipment business as if they were
organized under one business unit. Such statements include the following:
 
     - The Marion Power Shovel Company
 
     - Marion Power Shovel Pty. Ltd.
 
     - The South Africa Branch of INTOOL International B.V.
 
     - The Canadian mining division of Global-GIX Canada, Inc.
 
     The historical equity of these operations as well as permanent advances
from Global have been reported as "Combined Equity" in the Combined Balance
Sheet. Within Combined Equity, the Investment by Global account represents the
net assets invested in the Marion Business by Global including the advances that
will not be repaid.
 
INVENTORIES
 
     Inventories are stated at lower of cost (last-in, first-out method) or
market (market or estimated net realizable value). The excess of replacement
cost over the carrying value of inventories determined on a last-in, first-out
basis was $10,939,000. Advances from customers are netted against inventories to
the extent of related accumulated costs.
 
PROPERTY, PLANT AND EQUIPMENT
 
     Fixed assets are recorded at cost. Depreciation is provided over the
estimated useful lives of respective assets using the straight-line method for
financial reporting and accelerated methods for income tax purposes. Estimated
useful lives used for financial reporting purposes range from ten to forty years
for buildings and improvements and five to fifteen years for machinery and
equipment.
 
FOREIGN CURRENCY TRANSLATION
 
     The assets and liabilities of foreign operations are translated into U.S.
dollars using year-end exchange rates. Revenues and expenses are translated at
the average rates during the year. Adjustments resulting from this translation
are deferred and reflected as a separate component of Combined Equity.

 SURFACE MINING AND EQUIPMENT BUSINESS OF GLOBAL INDUSTRIAL TECHNOLOGIES, INC.
 
             NOTES TO COMBINED FINANCIAL STATEMENTS -- (CONTINUED)
 
REVENUE RECOGNITION
 
     Revenue from dragline contracts is recognized using the
percentage-of-completion method. Revenue from shovel contracts and all other
sales is recognized at time of shipment. At the time a loss on a contract
becomes known, the amount of the estimated loss is recognized in the combined
financial statements. Included in current liabilities as liabilities to
customers on uncompleted contracts are advances collected under shovel contracts
of $1,041,000.
 
IMPAIRMENT OF LONG-LIVED ASSETS
 
     In 1995, The Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to Be Disposed Of" ("SFAS 121").
SFAS 121 requires that long-lived assets and certain identifiable intangibles to
be held and used by an entity be reviewed for impairment when certain events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. This pronouncement is required to be adopted by the Marion
Business for the fiscal year beginning November 1, 1996. As of November 1, 1996,
adoption did not have a significant effect on the financial position or results
of operations of the Marion Business. See Note L.
 
NOTE B -- TRADE RECEIVABLES
 
     Trade receivables include the excess of revenues over advances of $426,000
related to a dragline contract. Billings on long-term contracts are made in
accordance with the payment terms as defined in the individual contracts.
 
     Trade receivables are reduced by an allowance for losses of $213,000.
 
NOTE C -- INVENTORIES
 
     Inventories at cost include material, labor and overhead and consist of the
following:

     Cumulative undistributed earnings of foreign operations that are considered
to be permanently reinvested, and on which U.S. income taxes have not been
provided by the Marion Business, amounted to approximately $23,700,000 at
October 31, 1996. It is not practicable to estimate the amount of additional tax
which would be payable upon repatriation of such earnings; however, due to
foreign tax credit limitations, higher effective U.S. income tax rates and
foreign withholding taxes, additional taxes could be incurred.
 
NOTE F -- PENSION AND RETIREMENT PLANS
 
     The Marion Business has two defined benefit pension plans which cover
substantially all hourly bargaining and nonbargaining unit employees in the
United States. Plan benefits are based primarily on years of service. In
addition, the Marion Business' salaried employees participate in the Global
Industrial Technologies, Inc. RIP Plan, which benefits are based primarily on
years of service and employees' qualifying compensation during the final years
of employment. All plans are funded in accordance with applicable laws and
regulations. Substantially all plan assets are invested in cash, short-term
investments, equity securities and fixed-income instruments. The remaining plan
assets are primarily invested in real estate.

rate used in measuring the accumulated postretirement benefit obligation was 11%
at October 31, 1996, declining .5% each year thereafter, to 5% in the year 2008
and beyond. A 1% increase in the assumed health care cost trend rate for each
year would increase the accumulated postretirement benefit obligation by
$270,000 and would increase the net periodic postretirement benefit cost for
1996 by $13,000.

     Two customers accounted for approximately 42% of the Marion Business' net
sales in 1996. The Marion Business is not dependent upon any one customer.
 
NOTE J -- TRANSACTIONS WITH GLOBAL
 
     The Marion Business has historically depended on Global for substantial
support, particularly financial. Global also performs certain services such as
insurance claim processing, data processing, and legal and tax support. Total
costs allocated to the Marion Business and included in the combined financial
statements are the following:
 
     (a) Administrative costs of $2,200,000 allocated based on the Marion
         Business' percentage of Global's total working capital, gross property,
         plant and equipment and goodwill.
 
     (b) Interest expense of $228,000 allocated on the same basis as (a) above.
 
     (c) Pension expense for salaried employees as discussed in Note F.
 
     (d) Income taxes as discussed in Note E.
 
     Global provides financing to the Marion Business through a non-interest
bearing intercompany account. This intercompany account has been classified with
the Investment by Global account in Combined Equity.
 
NOTE K -- COMMITMENTS, CONTINGENCIES AND CREDIT RISKS
 
     The Marion Business is involved in various litigation arising in the normal
course of business. It is the view of management that the Marion Business'
recovery or liability, if any, under pending litigation is not expected to have
a material effect on the Marion Business' financial position or results of
operations, although no assurance to that effect can be given.
 
     The Marion Business has product liability insurance subject to a deductible
of $1,000,000 per occurrence and has various limits of liability depending on
the insurance policy year in question. It is the view of management that the
final resolution of said claims and other similar claims which are likely to
arise in the future will not individually or in the aggregate have a material
effect on the Marion Business' financial position or results of operations,
although no assurance to that effect can be given.

</TABLE>
 
     A significant portion of the Marion Business' combined net sales are to
customers whose activities are related to the coal, copper and iron ore mining
industries, including some who are located in foreign countries. The Marion
Business generally extends credit to these customers and, therefore, collection
of receivables may be affected by the mining industry economy and the economic
conditions in the countries where the customers are located. However, the Marion
Business closely monitors extension of credit and has not experienced
significant credit losses. Also, most foreign sales are made to large,
well-established companies. The Marion Business generally requires collateral or
guarantees on foreign sales to smaller companies.
 
NOTE L -- DIVESTITURE
 
     In January, 1997, Global announced its strategic decision to divest itself
of the surface mining equipment business (i.e. the Marion Business). See
"Business -- The Marion Acquisition" included elsewhere in this Prospectus.

                                    PART II
                     INFORMATION NOT REQUIRED IN PROSPECTUS
 
ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     Section 145 of the Delaware General Corporation Law, as amended, provides
in regards to indemnification of directors and officers as follows:
 
     145. Indemnification of Officers, Directors, Employees and Agents;
Insurance.
 
     (a) A corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorneys'
fees), judgments, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.
 
     (b) A corporation shall have power to indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise against
expenses (including attorneys' fees) actually and reasonably incurred by him in
connection with the defense or settlement of such action or suit if he acted in
good faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation and except that no indemnification shall be
made in respect of any claim, issue or matter as to which such person shall have
been adjudged to be liable to the corporation unless and only to the extent that
the Court of Chancery or the court in which such action or suit was brought
shall determine upon application that, despite the adjudication of liability but
in view of all the circumstances of the case, such person is fairly and
reasonably entitled to indemnity for such expenses which the Court of Chancery
or such other court shall deem proper.
 
     (c) To the extent that a director, officer, employee or agent of a
corporation has been successful on the merits or otherwise in defense of any
action, suit or proceeding referred to in subsections (a) and (b), or in defense
of any claim, issue or matter therein, he shall be indemnified against expenses
(including attorneys' fees) actually and reasonably incurred by him in
connection therewith.
 
     (d) Any indemnification under subsections (a) and (b) (unless ordered by a
court) shall be made by the corporation only as authorized in the specific case
upon a determination that indemnification of the director, officer, employee or
agent is proper in the circumstances because he has met the applicable standard
of conduct set forth in subsections (a) and (b). Such determination shall be
made (1) by a majority vote of the directors who are not parties to such action,
suit or proceeding, even though less than a quorum, or (2) if there are no such
directors, or if such directors so direct, by independent legal counsel in a
written opinion, or (3) by the stockholders.
 
                                      II-1
<PAGE>   176
 
     (e) Expenses (including attorneys' fees) incurred by an officer or director
in defending any civil, criminal, administrative or investigative action, suit
or proceeding may be paid by the corporation in advance of the final disposition
of such action, suit or proceeding upon receipt of an undertaking by or on
behalf of such director or officer to repay such amount if it shall ultimately
be determined that he is not entitled to be indemnified by the corporation as
authorized in this Section. Such expenses (including attorneys' fees) incurred
by other employees and agents may be so paid upon such terms and conditions, if
any, as the board of directors deems appropriate.
 
     (f) The indemnification and advancement of expenses provided by, or granted
pursuant to, the other subsections of this section shall not be deemed exclusive
of any other rights to which those seeking indemnification or advancement of
expenses may be entitled under any by-law, agreement, vote of stockholders or
disinterested directors or otherwise, both as to action in his official capacity
and as to action in another capacity while holding such office.
 
     (g) A corporation shall have power to purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise against any liability asserted against him
and incurred by him in any such capacity, or arising out of his status as such,
whether or not the corporation would have the power to indemnity him against
such liability under the provisions of this section.
 
     (h) For purposes of this Section, references to "the corporation" shall
include, in addition to the resulting corporation, any constituent corporation
(including any constituent of a constituent) absorbed in a consolidation or
merger which, if its separate existence had continued, would have had power and
authority to indemnify its directors, officers, and employees or agents, so that
any person who is or was a director, officer, employee or agent of such
constituent corporation, or is or was serving at the request of such constituent
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, shall stand in the same
position under the provisions of this Section with respect to the resulting or
surviving corporation as he would have with respect to such constituent
corporation if its separate existence had continued.
 
     (i) For purposes of this Section, references to "other enterprises" shall
include employee benefit plans; references to "fines" shall include any excise
taxes assessed on a person with respect to any employee benefit plan; and
references to "serving at the request of the corporation" shall include any
service as a director, officer, employee or agent of the corporation which
imposes duties on, or involves services by, such director, officer, employee, or
agent with respect to an employee benefit plan, its participants, or
beneficiaries; and a person who acted in good faith and in a manner he
reasonably believed to be in the interest of the participants and beneficiaries
of an employee benefit plan shall be deemed to have acted in a manner "not
opposed to the best interests of the corporation" as referred to in this
Section.
 
     (j) The indemnification and advancement of expenses provided by, or granted
pursuant to, this section shall, unless otherwise provided when authorized or
ratified, continue as to a person who has ceased to be a director, officer,
employee or agent and shall inure to the benefit of the heirs, executors and
administrators of such a person.
 
     Subarticle E of Article 8 of the Wyoming Business Corporation Act, as
amended, provides in regards to indemnification of directors and officers as
follows:
 
sec. 17-16-850 Subarticle definitions.
 
     (a) In this subarticle:
 
          (i) "Corporation" includes any domestic or foreign predecessor entity
     of a corporation in a merger;
 
                                      II-2
<PAGE>   177
 
          (ii) "Director" or "officer" means an individual who is or was a
     director or officer, respectively, of a corporation or who, while a
     director or officer of the corporation, is or was serving at the
     corporation's request as a director, officer, partner, trustee, employee or
     agent of another domestic or foreign corporation, partnership, joint
     venture, trust, employee benefit plan or other entity. A director or
     officer is considered to be serving an employee benefit plan at the
     corporation's request if his duties to the corporation also impose duties
     on, or otherwise involve services by, him to the plan or to participants in
     or beneficiaries of the plan. "Director" or "officer" includes, unless the
     context requires otherwise, the estate or personal representative of a
     director or officer;
 
          (iii) "Disinterested director" means a director who, at the time of a
     vote referred to in W.S. 17-16-853 (c) or a vote or selection referred to
     in W.S. 17-16-855(b) or (c), is not: (A) A party to the proceeding; or (B)
     An individual having a familial, financial, professional or employment
     relationship with the director whose indemnification or advance for
     expenses is the subject of the decision being made, which relationship
     would, in the circumstances, reasonably be expected to exert an influence
     on the director's judgment when voting on the decision being made.
 
          (iv) "Expenses" includes counsel fees;
 
          (v) "Liability" means the obligation to pay a judgment, settlement,
     penalty, fine (including an excise tax assessed with respect to an employee
     benefit plan), or reasonable expenses incurred with respect to a
     proceeding;
 
          (vi) "Party" means an individual who was, is or is threatened to be
     made, a defendant or respondent in a proceeding;
 
          (vii) "Proceeding" means any threatened, pending or completed action,

     investigative and whether formal or informal.
 
sec. 17-16-851 Authority to indemnify.
 
     (a) Except as otherwise provided in this section, a corporation may
indemnify an individual who is a party to a proceeding because he is a director
against liability incurred in the proceeding if: (i) He conducted himself in
good faith; and (ii) He reasonably believed that his conduct was in or at least
not opposed to the corporation's best interests; and (iii) In the case of any
criminal proceeding, he had no reasonable cause to believe his conduct was
unlawful; or (iv) He engaged in conduct for which broader indemnification has
been made permissible or obligatory under a provision of the articles of
incorporation, as authorized by W.S. 17-16-202(b)(v).
 
     (b) A director's conduct with respect to an employee benefit plan for a
purpose he reasonably believed to be in the interests of the participants in and
beneficiaries of the plan is conduct that satisfies the requirement of paragraph
(a)(ii) of this section.

conviction, or upon a plea of nolo contendere or its equivalent is not, of
itself, determinative that the director did not meet the standard of conduct
described in this section.
 
     (d) Unless ordered by a court under W.S. 17-16-854(a)(iii) a corporation
may not indemnify a director under this section: (i) In connection with a
proceeding by or in the right of the corporation, except for reasonable expenses
incurred in connection with the proceeding if it is determined that the director
has met the standard of conduct under subsection (a) of this section; or (ii) In
connection with any proceeding with respect to conduct for which he was adjudged
liable on the basis that he received a financial benefit to which he was not
entitled.

<PAGE>   178
 
     A corporation shall indemnify a director who was wholly successful, on the
merits or otherwise, in the defense of any proceeding to which he was a party
because he was a director of the corporation against reasonable expenses
incurred by him in connection with the proceeding.
 
sec. 17-16-853 Advance for expenses.
 
     (a) A corporation may, before final disposition of a proceeding, advance
funds to pay for or reimburse the reasonable expenses incurred by a director who
is a party to a proceeding because he is a director if he delivers to the
corporation: (i) A written affirmation of his good faith belief that he has met
the standard of conduct described in W.S. 17-16-851 or that the proceeding
involves conduct for which liability has been eliminated under a provision of
the articles of incorporation as authorized by W.S. 17-16-202(b)(iv); and
(ii) His written undertaking to repay any funds advanced if he is not entitled
to mandatory indemnification under W.S. 17-16-852 and it is ultimately
determined that he has not met the standard of conduct described in W.S.
17-16-851. (iii) Repealed by Laws 1997, ch. 190, s 3.
 
     (b) The undertaking required by paragraph (a)(ii) of this section shall be
an unlimited general obligation of the director but need not be secured and may
be accepted without reference to the financial ability of the director to make
repayment.
 
     (c) Authorizations under this section shall be made: (i) By the board of
directors: (A) If there are two (2) or more disinterested directors, by a
majority vote of all the disinterested directors (a majority of whom shall for
such purpose constitute a quorum) or by a majority of the members of a committee
of two (2) or more disinterested directors appointed by such a vote; or (B) If
there are fewer than two (2) disinterested directors, by the vote necessary for
action by the board in accordance with W.S. 17-16-824(c), in which authorization
directors who do not qualify as disinterested directors may participate; or (ii)
By the shareholders, but shares owned by or voted under the control of a
director who at the time does not qualify as a disinterested director may not be
voted on the authorization.
 
sec. 17-16-854 Court-ordered indemnification and advance for expenses.
 
     (a) A director who is a party to a proceeding because he is a director may
apply for indemnification or an advance for expenses to the court conducting the
proceeding or to another court of competent jurisdiction. After receipt of an
application and after giving any notice it considers necessary, the court shall:
(i) Order indemnification if the court determines that the director is entitled
to mandatory indemnification under W.S. 17-16-852; (ii) Order indemnification or
advance for expenses if the court determines that the director is entitled to
indemnification or advance for expenses pursuant to a provision authorized by
W.S. 17-16-858(a); or (iii) Order indemnification or advance for expenses if the
court determines, in view of all the relevant circumstances, that it is fair and
reasonable: (A) To indemnify the director; or (B) To advance expenses to the
director, even if he has not met the standard of conduct set forth in W.S.
17-16-851(a), failed to comply with W.S. 17-16-853 or was adjudged liable in a
proceeding referred to in W.S. 17-16-851(d)(i) or (ii), but if he was adjudged
so liable his indemnification shall be limited to reasonable expenses incurred
in connection with the proceeding.
 
     (b) If the court determines that the director is entitled to
indemnification under paragraph (a)(i) of this section or to indemnification or
advance for expenses under paragraph (a)(ii) of this section, it shall also
order the corporation to pay the director's reasonable expenses incurred in
connection with obtaining court-ordered indemnification or advance for expenses.
If the court determines that the director is entitled to indemnification or
advance for expenses under paragraph (a)(iii) of this section, it may also order
the corporation to pay the director's reasonable expenses to obtain
court-ordered indemnification or advance for expenses.
 
sec. 17-16-855 Determination and authorization of indemnification.
 
                                      II-4
<PAGE>   179
 
     (a) A corporation may not indemnify a director under W.S. 17-16-851 unless
authorized for a specific proceeding after a determination has been made that
indemnification of the director is permissible because he has met the standard
of conduct set forth in W.S. 17-16-851.
 
     (b) The determination shall be made: (i) If there are two (2) or more
disinterested directors, by the board of directors by majority vote of all the
disinterested directors (a majority of whom shall for such purpose constitute a
quorum), or by a majority of the members of a committee of two (2) or more
disinterested directors appointed by such a vote; (ii) Repealed by Laws 1997,
ch. 190, s 3. (iii) By special legal counsel: (A) Selected in the manner
prescribed in paragraph (i) of this subsection; or (B) If there are fewer than
two (2) disinterested directors, selected by the board of directors (in which
selection directors who do not qualify as disinterested directors may
participate); or (iv) By the shareholders, but shares owned by or voted under
the control of a director who at the time does not qualify as a disinterested
director may not be voted on the determination.
 
     (c) Authorization of indemnification shall be made in the same manner as
the determination that indemnification is permissible, except that if there are
fewer than two (2) disinterested directors, authorization of indemnification
shall be made by those entitled under paragraph (b)(iii) of this section to
select special legal counsel.
 
sec. 17-16-856 Officers.
 
     (a) A corporation may indemnify and advance expenses under this subarticle
to an officer of the corporation who is a party to a proceeding because he is an
officer of the corporation: (i) To the same extent as a director; and (ii) If he
is an officer but not a director, to such further extent as may be provided by
the articles of incorporation, the bylaws, a resolution of the board of
directors or contract, except for: (A) Liability in connection with a proceeding
by or in the right of the corporation other than for reasonable expenses
incurred in connection with the proceeding; or (B) Liability arising out of
conduct that constitutes: (I) Receipt by him of a financial benefit to which he
is not entitled; (II) An intentional infliction of harm on the corporation or
the shareholders; or (III) An intentional violation of criminal law. (iii) A
corporation may also indemnify and advance expenses to a current or former
officer, employee or agent who is not a director to the extent, consistent with
public policy, that may be provided by its articles of incorporation, bylaws,
general or specific action of its board of directors or contract.
 
     (b) The provisions of paragraph (a)(ii) of this section shall apply to an
officer who is also a director if the basis on which he is made a party to the
proceeding is an act or omission solely as an officer.
 
     (c) An officer of a corporation who is not a director is entitled to
mandatory indemnification under W.S. 17-16-852, and may apply to a court under
W.S. 17-16-854 for indemnification or an advance for expenses, in each case to
the same extent to which a director may be entitled to indemnification or
advance for expenses under those provisions.
 
sec. 17-16-857 Insurance.
 
     A corporation may purchase and maintain insurance on behalf of an
individual who is a director or officer of the corporation, or who, while a
director or officer of the corporation, serves at the corporation's request as a
director, officer, partner, trustee, employee or agent of another domestic or
foreign corporation, partnership, joint venture, trust, employee benefit plan,
or other entity, against liability asserted against or incurred by him in that
capacity or arising from his status as a director or officer whether or not the
corporation would have power to indemnify or advance expenses to him against the
same liability under this subarticle.
 
sec. 17-16-858 Variation by corporate action; application of subarticle.
 
     (a) A corporation may, by a provision in its articles of incorporation or
bylaws or in a resolution adopted or a contract approved by its board of
directors or shareholders, obligate itself in advance of the act or omission
giving rise to a proceeding to provide indemnification in accordance with W.S.
 
                                      II-5
<PAGE>   180
 
17-16-851 or advance funds to pay for or reimburse expenses in accordance with
W.S. 17-16-853. Any such obligatory provision shall be deemed to satisfy the
requirements for authorization referred to in W.S. 17-16-853(c) and 17-16-
855(c). Any provision that obligates the corporation to provide indemnification
to the fullest extent permitted by law shall be deemed to obligate the
corporation to advance funds to pay for or reimburse expenses in accordance with
W.S. 17-16-853 to the fullest extent permitted by law, unless the provision
specifically provides otherwise.
 
     (b) Any provision pursuant to subsection (a) of this section shall not
obligate the corporation to indemnify or advance expenses to a director of a
predecessor of the corporation, pertaining to conduct with respect to the
predecessor, unless otherwise specifically provided. Any provision for
indemnification or advance for expenses in the articles of incorporation,
bylaws, or a resolution of the board of directors or shareholders of a
predecessor of the corporation in a merger or in a contract to which the
predecessor is a party, existing at the time the merger takes effect, shall be
governed by W.S. 17-16-1106(a)(iii).
 
     (c) A corporation may, by provision in its articles of incorporation, limit
any of the rights to indemnification or advance for expenses created by or
pursuant to this subarticle.
 
     (d) This subarticle does not limit a corporation's power to pay or
reimburse expenses incurred by a director or officer in connection with his
appearance as a witness in a proceeding at a time when he is not a party.
 
     (e) This subarticle does not limit a corporation's power to indemnify,
advance expenses to or provide or maintain insurance on behalf of an employee or
agent.
 
sec. 17-16-859 Exclusivity of subarticle.
 
     A corporation may provide indemnification or advance expenses to a director
or an officer only as permitted by this subarticle.
 
     Section(b)(iv) and (v) of Article 2 of the Wyoming Business Corporation
Act, as amended, provides in regard to indemnification and the limitation of
liability of directors and officers as follows:
 
     (b) The articles of incorporation may set forth:
 
                                      ****
 
     (iv) A provision eliminating or limiting the liability of a director to the
corporation or its shareholders for money damages for any action taken, or any
failure to take any action, as a director, except liability for: (A) The amount
of financial benefit received by a director to which he is not entitled; (B) An
intentional infliction of harm on the corporation or shareholders; (C) A
violation of W.S. 17-16-833; or (D) An intentional violation of criminal law;
and
 
     (v) A provision permitting or making obligatory indemnification of a
director for liability (as defined in W.S. 17-16-850(a)(v)) to any person for
any action taken, or failure to take any action, as a director, except liability
for: (A) Receipt of a financial benefit to which he is not entitled; (B) An
intentional infliction of harm on the corporation or shareholders; (C) A
violation of W.S. 17-16-833; or (D) An intentional violation of criminal law.
 
     Article VII of Von's By-laws provide in regard to indemnification of
directors, officers and employees as follows:
 
     Any person made a party to any civil or criminal action, suit or proceeding
by reason of the fact that he, his testator or interstate, is or was a director,
officer or employee of his corporation or of any corporation which he served as
such at the request of this corporation, shall be indemnified by the corporation
against the reasonable expenses, including without limitation, attorney's fees
and amounts paid to the corporation by him, actually and necessarily incurred by
or imposed upon him in connection with, or resulting from the defense of such
civil, criminal actions, suit or proceedings that such officer, director or
employee is liable for negligence or misconduct, in the performance of his
 
                                      II-6
<PAGE>   181
 
duties. In the case of a criminal action suit or proceedings, a conviction
(whether based on a plea of guilty or nolo contenders or its equivalent, or
after trial) shall not of itself be deemed an adjudication that such officer,
director or employee is liable for negligence or misconduct in the performance
of his duties. Any amount payable pursuant to this article may be determined and
paid, at the option of the person to be indemnified, pursuant to procedure set
forth from time to time in the by-laws or by any of the following procedures:
(a) order of the court having jurisdiction of any such civil or criminal action,
suit or proceedings, (b) resolution adopted by a majority of a quorum of the
board of directors of the corporation without counting in such majority or
quorum any interested directors, (c) resolution adopted by the holders of record
or a majority of the outstanding shares of capital stock of the corporation
having powers, or (d) order of any court having jurisdiction over the
corporation. Such right of indemnification shall not be exclusive of any other
right of the corporation, and the other persons above-mentioned, may have or
hereafter acquire, and without limiting the generality of such statement, they
shall be entitled to their respective rights of indemnification under any
charter provisions, by-laws, agreements, vote of stockholders, provisions of law
or otherwise as their rights under this article.
 
     Section 102(b)(7) of the Delaware General Corporation Law, as amended,
provides in regard to the limitation of liability of directors and officers as
follows --
 
     (b) In addition to the matters required to be set forth in the certificate
of incorporation by subsection (a) of this section, the certificate of
incorporation may also contain any or all of the following matters:
 
                                    * * * *
 
     (7) A provision eliminating or limiting the personal liability of a
director to the corporation or its stockholders for monetary damages for breach
of fiduciary duty as a director, provided that such provision shall not
eliminate or limit the liability of a director, (i) for any breach of the
director's duty of loyalty to the corporation or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) under Section 174 of this title, or (iv) for any
transaction from which the director derived an improper personal benefit. No
such provision shall eliminate or limit the liability of a director for any act
or omission occurring prior to the date when such provision becomes effective.
All references to this Paragraph to a director shall also be deemed to refer (x)
to a member of the governing body of a corporation which is not authorized to
issue capital stock, and (y) to such other person or persons, if any, who,
pursuant to a provision of the certificate of incorporation in accordance with
subsection (a) of sec.141 of this title, exercise or perform any of the powers
or duties otherwise conferred or imposed upon the board of directors by this
title.
 
     Article FIFTH of Bucyrus' Certificate of Incorporation, as amended,
provides in regard to the limitation of liability of directors and officers as
follows:
 
          (4) No director shall be personally liable to the Corporation or any
     of its stockholders for monetary damages for breach of fiduciary duty as a
     director, except for liability (i) for any breach of the director's duty of
     loyalty to the Corporation or its stockholders; (ii) for acts or omissions
     not in good faith or which involved intentional misconduct or a knowing
     violation of law, (iii) pursuant to Section 174 of the GCL or (iv) for any
     transaction from which the director derived an improper personal benefit.
     Any repeal or modification of this Article FIFTH by the stockholders of the
     Corporation shall not adversely affect any right or protection of a
     director of the Corporation existing at the time of such repeal or
     modification with respect to acts or omissions occurring prior to such
     repeal or modification.
 
     Provisions in the Certificate of Incorporation of Boonville relating to
liability of its officers and directors are similar to those of Bucyrus in all
material respects. The Certificate of Incorporation of Minserco does not contain
any similar provisions.

                                    * * * *
 
             (iv) A provision eliminating or limiting the liability of a
        director to the corporation or its shareholders for money damages for

        director to which he is not entitled; (B) An intentional infliction of
        harm on the corporation or shareholders; (C) A violation of W.S.

ITEM 21. EXHIBITS AND FINANCIAL STATEMENT SCHEDULES
 
     The Exhibit Index attached hereto following the Signature Pages is
incorporated herein by reference.
 
ITEM 22. UNDERTAKINGS
 
     Each of the undersigned Registrants hereby undertakes:
 
     (1) That, for purposes of determining any liability under the Securities
Act of 1933, each filing of the Company's annual report pursuant to section
13(a) or section 15(d) of the Securities Exchange Act of 1934 that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be the initial bona fide offering
thereof.
 
     (2) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers, and persons controlling the
Registrants pursuant to the foregoing provisions or otherwise, the Registrants
have been advised that in the opinion of the Securities and Exchange Commission
such indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrants of expenses
incurred or paid by a director, officer or person controlling the Registrants in
the successful defense of any action, suit or proceeding) is asserted by such
director, officer, or person in connection with the securities being registered,
the Registrants will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.
 
     (3) To respond to requests for information that is incorporated by
reference into the Prospectus pursuant to Item 4, 10(b), 11 or 13 of Form S-4,
within one business day of receipt of such request, and to send the incorporated
documents by first-class mail or equally prompt means. This includes information
contained in documents filed subsequent to the effective date of the
registration statement through the date responding to the request.
 
     (4) To supply by means of a post-effective amendment all information
concerning a transaction, and the company being acquired involved therein, that
was not the subject of and included in the registration statement when it became
effective.

                                  STOCKHOLDERS

of these By- Laws, an annual meeting of stockholders of the Corporation for the
election of directors and for the transaction of any other proper business
shall be held on the last Wednesday in April in each year, unless such day
shall fall on a legal holiday, in which case such meeting shall be held on the
next day thereafter not a legal holiday.  The annual meeting in each year shall
be held at such hour on said day and at such place within or without the State
of Delaware as may be fixed by the Board of Directors, or, if not so fixed, at
1:00 P.M. at the principal business office of the Corporation at 1100 Milwaukee
Avenue, South Milwaukee, Wisconsin 53172.

     Section 1.2 Special Meetings.  A special meeting of the holders of stock
of the Corporation entitled to vote an any business to be considered at any
such meeting may be called by the Chairman of the Board, the Vice Chairman of
the Board, or the President, and shall be called by the Chairman of the Board,
Vice Chairman of the Board or the Secretary when directed to do so by
resolution of the Board of Directors or at the written request of a majority of
the Directors.  Any such request shall state the purpose or purposes of the
proposed meeting.

     Section 1.3 Notice of Meetings.  Whenever stockholders are required or
permitted to take any action at a meeting, unless notice is waived in writing
by all stockholders entitled to

<PAGE>   5


vote at the meeting, a written notice of the meeting shall be given which shall
state the place, date and hour of the meeting, and, in the case of a special
meeting, the purpose or purposes for which the meeting is called.

     Unless otherwise provided by law, and except as to any stockholder duly
waiving notice, the written notice of any meeting shall be given personally or
by mail, not less than seven nor more than thirty days before the date of the
meeting to each stockholder entitled to vote at such meeting.  If mailed,
notice shall be deemed given when deposited in the United States mail, postage
prepaid, directed to the stockholder at his address as it appears on the
records of the Corporation.

     When a meeting is adjourned to another time or place, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken.  At the adjourned meeting the
Corporation may transact any business which might have been transacted at the
original meeting.  If, however, the adjournment is for more than thirty days,
or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder
of record entitled to vote at the meeting.

     Section 1.4 Quorum.  Except as otherwise provided by law or by the
Certificate of Incorporation or by these By-Laws in respect of the vote
required for a specified action, at any meeting of stockholders the holders of

meeting to another time or place and, except as provided in the last paragraph
at Section 1.3 of these By-Laws, notice need not be given of the adjourned
meeting.

     Section 1.5 Voting.  Whenever directors are to be elected at a meeting,
they shall be elected by a plurality of the votes cast at the meeting by the
holders of the class or classes of stock entitled to vote for them.  Whenever
any corporate action, other than the election of directors, is to be taken by
vote of stockholders at a meeting, it shall, except as otherwise required by
law or by the Certificate of Incorporation or by these By-Laws, be authorized
by a majority of the votes cast at the meeting by the holders of stock entitled
to vote thereon.

     Except as otherwise provided by law, or by the Certificate of
Incorporation, each holder of record of stock of the Corporation entitled to
vote on any matter at any meeting of stockholders shall be entitled to one vote
for each share of such stock standing in the name of such holder on the stock
ledger of the Corporation on the record date for the determination of the
stockholders entitled to vote at the meeting.

     Upon demand of any stockholder entitled to vote, the vote for directors or

otherwise the method of voting and the manner in which votes are counted shall
be discretionary with the presiding officer at the meeting.

stockholders the Chairman of the Board, or in his absence the Vice Chairman, or
in his absence the President, or if none be present, the appointee of the
meeting, shall preside.  The Secretary, or in his absence an Assistant
Secretary, or if none be present, the appointee of the presiding officer of the
meeting, shall act as secretary of the meeting.

     Section 1.7 Proxies.  Each stockholder entitled to vote at a meeting of
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from
its date, unless the proxy provides for a longer period.  Every proxy shall be
signed by the stockholder or by his duly authorized attorney.

     Section 1.8 List of Stockholders.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specified in the
notice of the meting, or, if not so specified, at the place where the meeting
is to be held.  The list shall also be produced and kept at the time and place
of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

     The stock ledger shall be the only evidence as to who are the stockholders
entitled to examine the stock ledger, the list required by this Section or the
books of the Corporation, or to vote in person or by proxy at any meeting of
stockholders.

     Section 1.9 Written Consent of Stockholders in Lieu of Meeting.  Any
action required by statute to be taken at any annual or special meeting of
stockholders of the Corporation, or any action which may be taken at any annual
or special meeting of the

                                      4

<PAGE>   8


stockholders, may be taken without a meeting, without prior notice and without
a vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of each class of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.  Prompt written notice of the taking of the corporation action
without a meeting by less than unanimous written consent shall be given to
those stockholders who have not consented in writing.  Any such written consent
may be given by one or any number of substantially concurrent written
instruments of substantially similar tenor signed by such stockholders, in
person or by attorney or proxy duly appointed in writing, and filed with the
Secretary or an Assistant Secretary of the Corporation.  Any such written
consent shall be effective as of the effective date thereof as specified
therein, provided that such date is not more than thirty days prior to the date
such written consent is filed as aforesaid, or, if no such date is so
specified, on the date such written consent is filed as aforesaid.

                                   ARTICLE II
                                   DIRECTORS

     Section 2.1 Number of Directors.  The Board of Directors shall consist of

Incorporation").

     Section 2.2 Election and Term of Directors.  Directors shall be elected
annually, by election at the annual meeting of stockholders or by written
consent of the holders of stock entitled to vote thereon in lieu of such
meeting.  If the annual election of directors is not held



                                      5
<PAGE>   9


on the date designated thereof, the directors shall cause such election to be
held as soon thereafter as convenient.  Each director shall hold office from
the time of his election and qualification until his successor is elected and
qualified or until his earlier resignation or removal.

     Section 2.3 Resignation.  Any director may resign at any time upon written
notice to the Corporation.  Any such resignation shall take effect at the time
specified therein or, if time be not specified, upon receipt thereof, and the
acceptance of such resignation, unless required by the terms thereof, shall not
be necessary to make such resignation effective.

     Section 2.4 Removal.  Any and all directors may be removed at any time,
with or without cause, by vote at a meeting or by written consent of the
holders of the class or classes of stock entitled to vote on the election of
such directors.

     Section 2.5 Meetings.  Meetings of the Board of Directors, regular or
special, may be held at any place within or without the State of Delaware.
Members of the Board of Directors, or of any Committee designated by the Board,
may participate in a meeting of such Board or Committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a
meeting by such means shall constitute presence in person at such meeting.  An
annual meeting of the Board of Directors shall be held after each annual
election of directors.  If such election occurs at an annual meeting of
stockholders, the annual meeting of the Board of Directors shall be held at the
same place and immediately following such meeting of stockholders, and no
notice thereof need be given.  If an annual election of directors occurs by
written consent in lieu of the annual meeting of stockholders, the annual
meeting of the Board of Directors shall take place as soon after such written
consent is duly filed with the Corporation as is practicable, either at the

<PAGE>   10


next regular meeting of the Board of Directors or at a special meeting.  The
Board of Directors may fix times and places for regular meetings of the Board
and no notice of such meetings need be given.  A special meeting of the Board
of Directors shall be held whenever called by the Chairman of the Board, Vice
Chairman or a majority of the directors for the time being in office, at such
time and place as shall be specified in the notice or waiver thereof.  Notice
of each special meeting shall be given by the Secretary or by a person calling
the meeting to each director by mailing the same, postage prepaid, not later
than the second day before the meeting, or personally or by telegraphing or
telephoning the same not later than the day before the meeting.

     Section 2.6 Quorum and Voting.  One-half of the directors entitled to vote
on any matter shall constitute a quorum for the transaction of business
pertaining to such matter, but if there be less than a quorum at any meeting of
the Board of Directors, a majority of the directors present may adjourn the
meeting from time to time, and no further notice thereof need be given other
than announcement at the meeting which shall be so adjourned.  Except as
otherwise provided by law, by the Certificate of Incorporation, or by these
By-Laws, the vote of a majority of the directors present at a meeting at which
a quorum is present shall be the act of the Board of Directors.

     Section 2.7 Written Consent of Directors in Lieu of a Meeting.  Any action
required or permitted to be taken at any meeting of the Board of Directors or
of any Committee thereof may be taken without a meeting if all members of the
Board or of such Committee, as the case may be, consent thereto in writing, and
the writing or writings are filed with the minutes of proceedings of the Board
or Committee.

     Section 2.8 Compensation.  Directors may receive compensation for services
to the Corporation in their capacities as directors or otherwise in such manner
and in such amounts as may be fixed from time to time by the Board of
Directors.

     Section 2.9 Contracts and Transactions Involving Directors.  No contract
or transaction between the Corporation and one or more of its directors or
officers, or between the Corporation and any other corporation, partnership,
association or other organization in which one or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer
is present at or participates in the meeting of the Board of Directors or
Committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose, if: (1) the material
facts as to his relationship or interest and as to the contract or transaction
are disclosed or are known to the Board of Directors or the committee, and the
Board or Committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (2) the material facts as to
his relationship or interest and as to the contract or transaction are

alternate members of any Committee, who may replace any absent or disqualified

present at any meeting and not disqualified from voting, whether or not he or

its meetings.  Unless otherwise provided by the Board of Directors, a majority
of any such Committee (or the member thereof, if only one) shall constitute a
quorum for the transaction of business, and the vote of a majority of the
members of such Committee present at

or for the purpose of any other lawful action, the Board of Directors may fix,
in advance, a record date, which shall not be more than sixty nor less than
seven days before the date of such meeting, nor more than sixty days prior to
any other action.  Only such stockholders as shall be stockholders of record on
the date so fixed shall be entitled to notice of, and to vote at, such meeting
and any adjournment thereof, or to give such consent, or to receive payment of
such dividend or other distribution, or to exercise such rights in respect of

action, as the case may be, notwithstanding any transfer of any stock on the
books of the Corporation after any record date so fixed.

for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of

business on the day next preceding the date on which notice is given, or, if
notice is waived by all stockholders entitled to vote at the meeting, at the
close of business on the day next preceding the day on which the meeting is
held, (2) the record date for determining stockholders entitled to express
consent to corporate action in writing without a meeting, when no prior action
by the Board of Directors is necessary, shall be at the close of business on

with the Corporation as provided in Section 1.9 of these By-Laws, and (3) the
record date for determining stockholders for any other purpose shall be at the
close of business on the day on which the Board of Directors adopts the
resolution relating thereto.

at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for
the adjourned meeting.

statute, or under any provision of the Certificate of Incorporation or these
By-Laws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  In the case of a stockholder, such waiver of notice may be signed by
such stockholder's attorney or proxy duly appointed in writing.  Attendance of
a person at a meeting shall constitute a waiver of notice of such meeting,
except when the person attends a meeting for the express purpose of objecting,
at the beginning of the meeting, to the transaction of business because the
meeting was not lawfully called or convened.  Neither the business to be
transacted at, nor the purpose of, any regular or special meeting of the
stockholders, directors or members of a committee of directors need be
specified in any written waiver of notice.

                                  Stockholders


     Section 1.1 Annual Meeting.  Except as otherwise provided in Section 1.9
of these By- Laws, an annual meeting of stockholders of the Corporation for the
election of directors and for the transaction of any other proper business
shall be held on the last Wednesday in April in each year, unless such day
shall fall on a legal holiday, in which case such meeting shall be held on the
next day thereafter not a legal holiday.  The annual meeting in each year shall
be held at such hour on said day and at such place within or without the State
of Delaware as may be fixed by the Board of Directors, or, if not so fixed, at
1:00 P.M. at the principal business office of the Corporation at 1100 Milwaukee
Avenue, South Milwaukee, Wisconsin 53172.

     Section 1.2 Special Meetings.  A special meeting of the holders of stock
of the Corporation entitled to vote on any business to be considered at any
such meeting may be called by the Chairman of the Board, the Vice Chairman of
the Board, or the President, and shall be called by the Chairman of the Board,
Vice Chairman of the Board or the Secretary when directed to do so by
resolution of the Board of Directors or at the written request of a majority of
the Directors.  Any such request shall state the purpose or purposes of the
proposed meeting.

     Section 1.3 Notice of Meetings.  Whenever stockholders are required or
permitted to take any action at a meeting, unless notice is waived in writing
by all stockholders entitled to

<PAGE>   5


vote at the meeting, a written notice of the meeting shall be given which shall
state the place, date and hour of the meeting, and, in the case of a special
meeting, the purpose or purposes for which the meeting is called.

     Unless otherwise provided by law, and except as to any stockholder duly
waiving notice, the written notice of any meeting shall be given personally or
by mail, not less than seven nor more than thirty days before the date of the
meeting to each stockholder entitled to vote at such meeting.  If mailed,
notice shall be deemed given when deposited in the United States mail, postage
prepaid, directed to the stockholder at his address as it appears on the
records of the Corporation.

     When a meeting is adjourned to another time or place, notice need not be
given of the adjourned meeting if the time and place thereof are announced at
the meeting at which the adjournment is taken.  At the adjourned meeting the
Corporation may transact any business which might have been transacted at the
original meeting.  If, however, the adjournment is for more than thirty days,
or if after the adjournment a new record date is fixed for the adjourned
meeting, a notice of the adjourned meeting shall be given to each stockholder
of record entitled to vote at the meeting.

     Section 1.4 Quorum.  Except as otherwise provided by law or by the
Certificate of Incorporation or by these By-Laws in respect of the vote
required for a specified action, at any meeting of stockholders the holders of

business, but the stockholders present, although less than a quorum, may
adjourn the


                                      2
<PAGE>   6


meeting to another time or place and, except as provided in the last paragraphs
of Section 1.3 of these By-Laws, notice need not be given of the adjourned
meeting.

     Section 1.5 Voting.  Whenever directors are to be elected at a meeting,
they shall be elected by a plurality of the votes cast at the meeting by the
holders of the class or classes of stock entitled to vote for them.  Whenever
any corporate action, other than the election of directors, is to be taken by
vote of stockholders at a meeting, it shall, except as otherwise required by
law or by the Certificate of Incorporation or by these By-Laws, be authorized
by a majority of the votes cast at the meeting by the holders of stock entitled
to vote thereon.

     Except as otherwise provided by law, or by the Certificate of
Incorporation, each holder of record of stock of the Corporation entitled to
vote on any matter at any meeting of stockholders shall be entitled to one vote
for each share of such stock standing in the name of such holder on the stock
ledger of the Corporation on the record date for the determination of the
stockholders entitled to vote at the meeting.

     Upon demand of any stockholder entitled to vote, the vote for directors or
the vote on any other matter at a meeting shall be by written ballot, but
otherwise the method of voting and the manner in which votes are counted shall
be discretionary with the presiding officer at the meeting.

     Section 1.6 Presiding Officer and Secretary.  At every meeting of
stockholders the Chairman of the Board, or in his absence the Vice Chairman, or
in his absence the President, or if none be present, the appointee of the
meeting, shall preside.  The Secretary, or in his absence an Assistant
Secretary, or if none be present, the appointee of the presiding officer of the
meeting, shall act as secretary of the meeting.

     Section 1.7 Proxies.  Each stockholder entitled to vote at a meeting of
stockholders or to express consent or dissent to corporate action in writing
without a meeting may authorize another person or persons to act for him by
proxy, but no such proxy shall be voted or acted upon after three years from
its date, unless the proxy provides for a longer period.  Every proxy shall be
signed by the stockholder or by his duly authorized attorney.

     Section 1.8 List of Stockholders.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten days before
every meeting of stockholders, a complete list of the stockholders entitled to
vote at the meeting, arranged in alphabetical order, and showing the address of
each stockholder and the number of shares registered in the name of each
stockholder.  Such list shall be open to the examination of any stockholder,
for any purpose germane to the meeting, during ordinary business hours, for a
period of at least ten days prior to the meeting, either at a place within the
city where the meeting is to be held, which place shall be specified in the
notice of the meeting, or, if not so specified, at the place where the meeting
is to be held.  The list shall also be produced and kept at the time and place
of the meeting during the whole time thereof, and may be inspected by any
stockholder who is present.

     The stock ledger shall be the only evidence as to who are the stockholders
entitled to examine the stock ledger, the list required by this Section or the
books of the Corporation, or to vote in person or by proxy at any meeting of
stockholders.

     Section 1.9 Written Consent of Stockholders in Lieu of Meeting.  Any
action required by statute to be taken at any annual or special meeting of
stockholders of the Corporation, or any action which may be taken at any annual
or special meeting of the


                                      4
<PAGE>   8

stockholders, may be taken without a meeting, without prior notice and without
a vote, if a consent in writing, setting forth the action so taken, shall be
signed by the holders of each class of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted.  Prompt written notice of the taking of the corporation action
without a meeting by less than unanimous written consent shall be given to
those stockholders who have not consented in writing.  Any such written consent
may be given by one or any number of substantially concurrent written
instruments of substantially similar tenor signed by such stockholders, in
person or by attorney or proxy duly appointed in writing, and filed with the
Secretary or an Assistant Secretary of the Corporation.  Any such written
consent shall be effective as of the effective date thereof as specified
therein, provided that such date is not more than thirty days prior to the date
such written consent is filed as aforesaid, or, if no such date is so
specified, on the date such written consent is filed as aforesaid.

                                   ARTICLE II
                                   DIRECTORS

Incorporation").

     Section 2.2 Election and Term of Directors.  Directors shall be elected
annually, by election at the annual meeting of stockholders or by written
consent of the holders of stock entitled to vote thereon in lieu of such
meeting.  If the annual election of directors is not held on the date
designated thereof, the directors shall cause such election to be held as soon


                                      5
<PAGE>   9


thereafter as convenient.  Each director shall hold office from the time of his
election and qualification until his successor is elected and qualified or
until his earlier resignation or removal.

     Section 2.3 Resignation.  Any director may resign at any time upon written
notice to the Corporation.  Any such resignation shall take effect at the time
specified therein or, if time be not specified, upon receipt thereof, and the
acceptance of such resignation, unless required by the terms thereof, shall not
be necessary to make such resignation effective.

     Section 2.4 Removal.  Any and all directors may be removed at any time,
with or without cause, by vote at a meeting or by written consent of the
holders of the class or classes of stock entitled to vote on the election of
such directors.

     Section 2.5 Meetings.  Meetings of the Board of Directors, regular or
special, may be held at any place within or without the State of Delaware.
Members of the Board of Directors, or of any Committee designated by the Board,
may participate in a meeting of such Board or Committee by means of conference
telephone or similar communications equipment by means of which all persons
participating in the meeting can hear each other, and participation in a
meeting by such means shall constitute presence in person at such meeting.  An
annual meeting of the Board of Directors shall be held after each annual
election of directors.  If such election occurs at an annual meeting of the
stockholders, the annual meting of the Board of Directors shall be held at the
same place and immediately following such meeting of stockholders, and no
notice thereof need be given.  If an annual election of directors occurs by
written consent in lieu of the annual meeting of stockholders, the annual
meeting of the Board of Directors shall take place as soon after such written
consent is duly


                                      6
<PAGE>   10


filed with the Corporation as is practicable, either at the next regular
meeting of the Board of Directors or at a special meeting.  The Board of
Directors may fix times and places for regular meetings of the Board and no
notice of such meetings need be given.  A special meeting of the Board of
Directors shall be held whenever called by the Chairman of the Board, Vice
Chairman or a majority of the directors for the time being in office, at such
time and place as shall be specified in the notice or waiver thereof.  Notice
of each special meeting shall be given by the Secretary or by a person calling
the meeting to each director by mailing the same, postage prepaid, not later
than the second day before the meeting, or personally or by telegraphing or
telephoning the same not later than the day before the meeting.

     Section 2.6 Quorum and Voting.  One-half of the directors entitled to vote
on any matter shall constitute a quorum for the transaction of business
pertaining to such matter, but if there be less than a quorum at any meeting of
the Board of Directors, a majority of the directors present may adjourn the
meeting from time to time, and no further notice thereof need be given other
than announcement at the meeting which shall be so adjourned.  Except as
otherwise provided by law, by the Certificate of Incorporation, or by these
By-Laws, the vote of a majority of the directors present at a meeting at which
a quorum is present shall be the act of the Board of Directors.

     Section 2.7 Written Consent of Directors in Lieu of a Meeting.  Any action
required or permitted to be taken at any meeting of the Board of Directors or
of any Committee thereof may be taken without a meeting if all members of the
Board or of such Committee, as the case may be, consent thereto in writing, and
the writing or writings are filed with the minutes of proceedings of the Board
or Committee.

     Section 2.8 Compensation.  Directors may receive compensation for services
to the Corporation in their capacities as directors or otherwise in such manner
and in such amounts as may be fixed from time to time by the Board of
Directors.

     Section 2.9 Contracts and Transactions Involving  Directors.  No contract
or transaction between the Corporation and one or more of its directors or
officers, or between the Corporation and any other corporation, partnership,
association or other organization in which one or more of its directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for this reason, or solely because the director or officer
is present at or participates in the meeting of the Board of Directors or
Committee thereof which authorizes the contract or transaction, or solely
because his or their votes are counted for such purpose, if: (1) the material
facts as to his relationship or interest and as to the contract or transaction
are disclosed or are known to the Board of Directors or the Committee, and the
Board or Committee in good faith authorizes the contract or transaction by the
affirmative votes of a majority of the disinterested directors, even though the
disinterested directors be less than a quorum; or (2) the material facts as to
his relationship or interest and as to the contract or transaction are
disclosed or are known to the stockholders entitled to vote thereon, and the
contract or transaction is specifically approved in good faith by vote of the
stockholders; or (3) the contract or transaction is fair as to the Corporation
as of the time it is authorized, approved or ratified, by the Board of
Directors, a Committee thereof, or the stockholders.  Common or interested
directors may be counted in determining the presence of a quorum at a meeting
of the Board of Directors or of a Committee which authorizes the contract or
transaction.

                      COMMITTEES OF THE BOARD OF DIRECTORS

     Section 3.1 Appointment and Powers.  The Board of Directors may from time
to time, by resolution passed by a majority of the directors, designate one or
more Committees, each Committee to consist of one or more directors of the
Corporation.  The Board of Directors may designate one or more directors as
alternate members of any Committee, who may replace any absent or disqualified
member at any meeting of the Committee.  The resolution of the Board of
Directors may, in addition or alternatively, provide that in the absence or
disqualification of a member of a Committee, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board
of Directors to act at the meeting in the place of any such absent or
disqualified member.  Any such Committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the
business and affairs of the Corporation and may authorize the seal of the
Corporation to be affixed to all papers which may require it, except as
otherwise provided by law.  Unless the resolution of the Board of Directors
expressly so provides, no such Committee shall have the power or authority to
declare a dividend or to authorize the issuance of stock.  Any such Committee
may adopt rules governing the method of calling and time and place of holding
its meetings.  Unless otherwise provided by the Board of Directors, a majority
of any such Committee (or the member thereof, if only one) shall constitute a
quorum for the transaction of business, and the vote of a majority of the
members of such Committee present at a meeting at which a

                                      9
<PAGE>   13


quorum is present shall be the act of such Committee.  Each such Committee
shall keep a record of its acts and proceedings and shall report thereon to the
Board of Directors whenever requested so to do.  Any or all members of any such
Committee may be removed, with or without cause, by resolution of the Board of
Directors.
                                   ARTICLE IV
                         OFFICERS, AGENTS AND EMPLOYEES

     Section 4.1 Appointment and Term of Office.  The officers of the
Corporation shall include a Chairman of the Board, a Vice Chairman of the
Board, a President, a General Manager, a Secretary, a Treasurer and a
Controller, and may include one or more Vice Presidents.  All such officers
shall be elected by the Board of Directors and the Chairman of the Board and
Vice Chairman of the Board shall be chosen from among the directors.  Any
number of such offices may be held by the same person, but no officer shall
execute, acknowledge or verify any instrument in more than one capacity.
Except as may be prescribed otherwise by the Board of Directors, all such
officers shall hold their offices at the pleasure of the Board for an unlimited
term and need not be re-elected annually or at any other periodic interval.
The Board of Directors may appoint, and may delegate power to appoint, such
other officers, agents and employees as it may deem necessary or proper, who
shall hold their offices or positions for such terms, have such authority and
perform such duties as may from time to time be determined by or pursuant to
authorization of the Board of Directors.

         controlled by the Permitted Holders), and, in the case of any such
         merger or consolidation, the securities of Bucyrus that are
         outstanding immediately prior to such transaction and which represent
         100% of the aggregate voting power of the Voting Stock of Bucyrus are

         transaction, at least a majority of the aggregate voting power of the

means the ratio of (i) the aggregate amount of EBITDA for the period of the

available to (ii) Consolidated Fixed Charges for such four fiscal quarters;
provided, however, that (1) if Bucyrus or any Restricted Subsidiary has
Incurred any Indebtedness since the beginning of such period that remains
outstanding on such date of determination or if the transaction giving rise to
the need to calculate the Consolidated Coverage Ratio is an Incurrence of
Indebtedness, or both, EBITDA and Consolidated Fixed Charges for such period
shall be calculated after giving effect on a pro forma basis to such
Indebtedness as if such Indebtedness had been Incurred on the first day of such
period and the discharge of any other Indebtedness repaid, repurchased,
defeased or otherwise discharged with the proceeds of such new Indebtedness as
if such discharge had occurred on the first day of such period (except that, in
the case of Indebtedness used to finance working capital needs incurred under a
revolving credit or similar arrangement, the amount thereof shall be deemed to
be the average daily balance of such Indebtedness during such
four-fiscal-quarter period), (2) if since the beginning of such period Bucyrus
or any Restricted Subsidiary shall have made any Asset Disposition, the EBITDA
for such period shall be reduced by an amount equal to the EBITDA (if positive)
directly attributable to the assets which are the subject of such Asset
Disposition for such period, or increased by an amount equal to the EBITDA (if
negative) directly attributable thereto for such period, and Consolidated Fixed
Charges for such period shall be reduced by an amount equal to the Consolidated
Fixed Charges directly attributable to any Indebtedness of Bucyrus or any
Restricted Subsidiary repaid,





<PAGE>   12

                                      -6-

repurchased, defeased, assumed by a third person (to the extent Bucyrus and its
Restricted Subsidiaries are no longer liable for such Indebtedness) or
otherwise discharged with respect to Bucyrus and its continuing Restricted
Subsidiaries in connection with such Asset Disposition for such period (or, if
the Capital Stock of any Restricted Subsidiary is sold, the Consolidated Fixed
Charges for such period directly attributable to the Indebtedness of such
Restricted Subsidiary to the extent Bucyrus and its continuing Restricted
Subsidiaries are no longer liable for such Indebtedness after such sale), (3)
if since the beginning of such period Bucyrus shall have consummated a Public
Equity Offering following which there is a Public Market, Consolidated Fixed
Charges for such period shall be reduced by an amount equal to the Consolidated
Fixed Charges directly attributable to any Indebtedness of Bucyrus or any
Restricted Subsidiary repaid, repurchased, defeased or otherwise discharged
with respect to Bucyrus and its Restricted Subsidiaries in connection with such
Public Equity Offering for such period, (4) if since the beginning of such
period Bucyrus or any Restricted Subsidiary (by merger or otherwise) shall have
made an Investment in any Restricted Subsidiary (or any Person which becomes a
Restricted Subsidiary) or an acquisition of assets, which acquisition
constitutes all or substantially all of an operating unit of a business,
including any such Investment or acquisition occurring in connection with a
transaction requiring a calculation to be made hereunder, EBITDA and
Consolidated Fixed Charges for such period shall be calculated after giving pro
forma effect thereto (including the Incurrence of any Indebtedness) as if such
Investment or acquisition occurred on the first day of such period and (5) if
since the beginning of such period any Person (that subsequently became a
Restricted Subsidiary or was merged with or into Bucyrus or any Restricted
Subsidiary since the beginning of such period) shall have made any Asset
Disposition, any Investment or acquisition of assets that would have required
an adjustment pursuant to clause (3) or (4) above if made by Bucyrus or a
Restricted Subsidiary during such period, EBITDA and Consolidated Fixed Charges
for such period shall be calculated after giving pro forma effect thereto as if
such Asset Disposition, Investment or acquisition occurred on the first day of
such period.  For purposes of this definition, whenever pro forma effect is to
be given to an acquisition of assets, the amount of income, earnings or expense
relating thereto and the amount of Consolidated Fixed Charges associated with
any Indebtedness Incurred in connection therewith, the pro forma calculations
shall be prepared in accordance with Article II of Regulation S-X promulgated
by the Commission as determined in good faith by a responsible financial or
accounting Officer of Bucyrus.  If any Indebtedness bears a floating rate of
interest and is being given pro forma effect, the interest of such Indebtedness
shall be calculated as if the





<PAGE>   13

                                      -7-

rate in effect on the date of determination had been the applicable rate for

excess of 12 months).

net income of any such Person for such period shall be included in such
Consolidated Net Income up to the aggregate amount of cash actually distributed

instrument and governmental regulation applicable to such Restricted Subsidiary
or its stockholders; (v) gain (but not loss) (less all fees and expenses

repurchase price shall be calculated in accordance with the terms of such

value of, such Disqualified Stock, such fair market value is to be determined
in good faith by the board of directors of the issuer of such Disqualified
Stock.  The amount of Indebtedness of any Person at any date shall be the

                                 THE SECURITIES

                 SECTION 2.1.     Form and Dating.

                 (a)      The Initial Securities and the Trustee's certificate
of authentication relating thereto shall be substantially in the form of
Exhibit A hereto.  The Exchange Securities and the Trustee's certificate of
authentication relating thereto shall be substantially in the form of Exhibit B
hereto.  The Securities may have notations, legends or endorsements required by
law, stock exchange rules, agreements to which Bucyrus is subject, if any, or
usage (provided that any such notation, legend or endorsement is in a form
acceptable to Bucyrus).  Each Security shall be dated the date of its
authentication.  If required, the Securities may bear the appropriate legend
regarding any original issue discount for federal income tax purposes.  Each
Security shall have an executed Guarantee from each of the Guarantors.

                 The terms and provisions contained in the Securities, annexed
hereto as Exhibits A and B, shall constitute, and are hereby expressly made, a
part of this Indenture and, to the extent applicable, Bucyrus, the Guarantors
and the Trustee, by their execution and delivery of this Indenture, expressly
agree to such terms and provisions and to be bound thereby.

                 (b)      Global Securities.  The Securities offered and sold
in reliance on Rule 144A and Securities offered and sold in reliance on
Regulation S shall be issued initially in the form of one or more permanent
Global Securities ("Global Securities") in definitive, fully registered form
without interest coupons, in substantially the form of Exhibit A, which shall
be deposited on behalf of the purchasers of the Securities represented thereby
with the Trustee, at the Trustee's office in New York City, as custodian for
the Depository, and registered in the name of the Depository or a nominee of
the Depository, duly executed by





<PAGE>   31

                                      -25-

Bucyrus (and having an executed Guarantee endorsed thereon) and authenticated
by the Trustee as hereinafter provided and shall bear the legend set forth in
Section 2.13.  The aggregate principal amount of the Global Securities may from
time to time be increased or decreased by adjustments made on the records of
the Trustee and the Depository or its nominee in the limited circumstances
hereinafter provided.

                 Securities issued in exchange for interests in Global
Securities pursuant to Section 2.6 may be issued in the form of permanent
certificated Securities in registered form in substantially the form set forth
in Exhibit A (the "Physical Securities").

                 SECTION 2.2.     Execution and Authentication.  An Officer of
Bucyrus and each Guarantor shall sign the Securities and the Guarantees,
respectively, by manual or facsimile signature.  If an Officer whose signature
is on a Security no longer holds that office at the time the Trustee
authenticates the Security, the Security shall be valid nevertheless.  A
Security shall not be valid until an authorized signatory of the Trustee
manually signs the certificate of authentication on the Security.  The
signature shall be conclusive evidence that the Security has been authenticated
under this Indenture.  The Trustee shall authenticate and make available for
delivery (i) Initial Securities for original issue in an aggregate principal
amount of $150,000,000 and (ii) Exchange Securities from time to time for issue
only in exchange for a like principal amount of Initial Securities, in each
case, upon a written order of Bucyrus signed by an Officer of Bucyrus.  Such
order shall specify the amount of the Securities to be authenticated and the
date on which the Securities are to be authenticated.  The aggregate principal
amount of Securities outstanding at any time may not exceed $150,000,000 except
as provided in Section 2.7.  The Trustee may appoint an authenticating agent
acceptable to Bucyrus to authenticate the Securities, upon the consent of
Bucyrus to such appointment.  Unless limited by the terms of such appointment,
an authenticating agent may authenticate Securities whenever the Trustee may do
so.  Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent.  An authenticating agent has the same rights as
any Registrar, Paying Agent or agent for service of notices and demands.

                 SECTION 2.3.     Registrar and Paying Agent.  Bucyrus shall
maintain an office or agency where Securities may be presented for registration
of transfer or for exchange (the "Registrar") and an office or agency where
Securities may be presented for payment (the "Paying Agent").  The Registrar,
acting on behalf of and as agent for Bucyrus, shall keep a register (the
"Securities Register") of the Securities and of their transfer and





<PAGE>   32

                                      -26-

exchange.  Bucyrus may have one or more co-registrars and one or more
additional paying agents.

                 The term "Paying Agent" includes any additional paying agent.
Bucyrus shall enter into an appropriate agency agreement with any Registrar,
Paying Agent or co-registrar not a party to this Indenture, which shall
incorporate the terms of the TIA.  The agreement shall implement the provisions
of this Indenture that relate to such agent.  Bucyrus shall notify the Trustee
of the name and address of any such agent.  If Bucyrus fails to maintain a
Registrar or Paying Agent, the Trustee shall act as such and shall be entitled
to appropriate compensation therefor pursuant to Section 7.7.  Bucyrus or a
Subsidiary thereof Neither the Company nor any of its Affiliates may act as
Paying Agent, Registrar, co-Registrar or transfer agent.

                 Bucyrus initially appoints the Trustee as Registrar and Paying
Agent in connection with the Securities, until such time as the Trustee has
resigned or a successor has been appointed.  Any of the Registrar, the Paying
Agent or any other agent may resign upon 30 days' notice to Bucyrus.

                 SECTION 2.4.     Paying Agent To Hold Money in Trust.  On or
prior to each due date of the principal and interest on any Security, Bucyrus
shall deposit with the Paying Agent a sum sufficient to pay such principal and
interest when so becoming due.  Bucyrus shall require each Paying Agent (other
than the Trustee) to agree in writing that the Paying Agent shall hold in trust
for the benefit of Securityholders or the Trustee all money held by the Paying
Agent for the payment of principal of or interest on the Securities and shall
notify the Trustee of any default by Bucyrus in making any such payment.  If
Bucyrus or a Subsidiary acts as Paying Agent, it shall segregate the money held
by it as Paying Agent and hold it as a separate trust fund.  Bucyrus at any
time may require a Paying Agent to pay all money held by it to the Trustee and
to account for any funds disbursed by the Paying Agent.  Upon complying with
this Section, the Paying Agent shall have no further liability for the money
delivered to the Trustee.

                 SECTION 2.5.     Holder Lists.  The Trustee shall preserve in
as current a form as is reasonably practicable the most recent list available
to it of the names and addresses of Holders.  If the Trustee is not the
Registrar, Bucyrus shall furnish to the Trustee, in writing at least five
Business Days before each interest payment date and at such other times as the
Trustee may request in writing, a list in such form and as of such date as the
Trustee may reasonably require of the names and addresses of Securityholders;
provided, however, that as long as the Trustee is the Registrar, no such list
need be furnished.

                                      -27-

                 SECTION 2.6.     Transfer and Exchange.  The Securities shall
be issued in registered form and shall be transferable only upon the surrender
of a Security for registration of transfer.  When a Security is presented to
the Registrar or a co-registrar with a request to register a transfer, the
Registrar and the Trustee may require a Holder, among other things, to furnish
appropriate endorsements and transfer documents and the Registrar shall record
in the Securities Register the transfer as requested if the requirements of
Section 8-401(1) of the Uniform Commercial Code are met, and thereupon one or
more new Securities in the same aggregate principal amount shall be issued to
the designated assignee or transferee and the old Security will be returned to
Bucyrus.  When Securities are presented to the Registrar or a co- registrar
with a request to exchange them for an equal principal amount of Securities of
other denominations, the Registrar shall make the exchange as requested, in the
same manner, if the same requirements are met.  To permit registration of
transfers and exchanges, Bucyrus shall execute and the Trustee shall
authenticate Securities and each of the Guarantors shall execute a Guarantee
thereon at the Registrar's or co- registrar's request.  Bucyrus may require
payment of a sum sufficient to pay all taxes, assessments or other governmental
charges in connection with any transfer or exchange pursuant to this Section.
Bucyrus shall not be required to make and the Registrar need not register
transfers or exchanges of Securities selected for redemption (except, in the
case of Securities to be redeemed in part, the portion thereof not to be
redeemed) or any Securities for a period of 15 days before a selection of
Securities to be redeemed or 15 days before an interest payment date.


                 Prior to the due presentation for registration of transfer of
any Security, Bucyrus, the Trustee, the Paying Agent, the Registrar or any
co-registrar may deem and treat the person in whose name a Security is
registered as the absolute owner of such Security for the purpose of receiving
payment of principal of and interest on such Security and for all other
purposes whatsoever, whether or not such Security is overdue, and none of
Bucyrus, the Trustee, the Paying Agent, the Registrar or any co-registrar shall
be affected by notice to the contrary.

                 All Securities issued upon any transfer or exchange pursuant
to the terms of this Indenture will evidence the same debt and will be entitled
to the same benefits under this Indenture as the Securities surrendered upon
such transfer or exchange.

                 With respect to Global Securities:

                 (1)      Each Global Security authenticated under this
         Indenture shall (i) be registered in the name of the Depository
         designated for such Global Security or a nominee





<PAGE>   34

                                      -28-

         thereof, (ii) be deposited with such Depository or a nominee thereof
         or custodian therefor, (iii) bear legends as set forth in Section 2.13
         and (iv) constitute a single Security for all purposes of this
         Indenture.

                 (2)      Transfers of a Global Security shall be limited to
         transfers in whole but not in part to the Depository, its successors
         or their respective nominees.  Interests of beneficial owners in a
         Global Security may be transferred or exchanged for Physical
         Securities in accordance with the rules and procedures of the
         Depository and the provisions of Section 2.14.  In addition, a Global
         Security is exchangeable for certificated Securities if (i) the
         Depository notifies Bucyrus that it is unwilling or unable to continue
         as a Depository for such Global Security or if at any time the
         Depository ceases to be a clearing agency registered under the
         Exchange Act, (ii) Bucyrus executes and delivers to the Trustee a
         notice that such Global Security shall be so transferable,
         registrable, and exchangeable, and such transfers shall be registrable
         or (iii) there shall have occurred and be continuing a Default.  Any
         Global Security that is exchangeable for certificated Securities
         pursuant to the preceding sentence will be transferred to, and
         registered and exchanged for, certificated Securities in authorized
         denominations, without legends applicable to a Global Security, and
         registered in such names as the Depository holding such Global
         Security may direct.  Subject to the foregoing, a Global Security is
         not exchangeable, except for a Global Security of like denomination to
         be registered in the name of the Depository or its nominee.  In the
         event that a Global Security becomes exchangeable for certificated
         Securities, (i) certificated Securities will be issued only in fully
         registered form in denominations of $1,000 or integral multiples
         thereof, (ii) payment of principal, any repurchase price, and interest
         on the certificated Securities will be payable, and the transfer of
         the certificated Securities will be registrable, at the office or
         agency of Bucyrus maintained for such purposes, and (iii) no service
         charge will be made for any registration or transfer or exchange of
         the certificated Securities, although Bucyrus may require payment of a
         sum sufficient to cover any tax or governmental charge imposed in
         connection therewith.

                 (3)      Securities issued in exchange for a Global Security
         or any portion thereof shall have an aggregate principal amount equal
         to that of such Global Security or portion thereof to be so exchanged,
         shall be registered in such names and be in such authorized
         denominations as the Depository shall designate and shall bear the
         applicable legends provided for herein.  Any Global Security to be
         exchanged in whole shall be surrendered by the Depository to





<PAGE>   35

                                      -29-

         the Trustee.  With respect to any Global Security to be exchanged in
         part, either such Global Security shall be so surrendered for exchange
         or, if the Trustee is acting as custodian for the Depository or its
         nominee with respect to such Global Security, the principal amount
         thereof shall be reduced, by an amount equal to the portion thereof to
         be so exchanged, by means of an appropriate adjustment made on the
         records of the Trustee.  Upon any such surrender or adjustment, the
         Trustee shall authenticate and deliver the Security issuable on such
         exchange to or upon the order of the Depository or an authorized
         representative thereof.

                 (4)      Every Security authenticated and delivered upon
         registration of transfer of, or in exchange for or in lieu of, a
         Global Security or any portion mutilated thereof, whether pursuant to
         this Section 2.6, Section 2.7, 2.9, 2.14 or otherwise, shall be
         authenticated and delivered in the form of, and shall be, a Global
         Security, unless such Security is registered in the name of a Person
         other than the Depository for such Global Security or a nominee
         thereof.  Members of, or participants in, the Depository ("
         Participants") shall have no rights under this Indenture with respect
         to any Global Security held on their behalf by the Depository or by
         the Trustee as the custodian of the Depository or under such Global
         Security, and the Depository may be treated by Bucyrus, the Trustee
         and any agent of Bucyrus or the Trustee as the absolute owner of such
         Global Security for all purposes whatsoever.  Notwithstanding the
         foregoing, nothing herein shall prevent Bucyrus, the Trustee or any
         agent of Bucyrus or the Trustee from giving effect to any written
         certification, proxy or other authorization furnished by the
         Depository or impair, as between the Depository and its Participants,
         the operation of customary practices of such Depository governing the
         exercise of the rights of a holder of a beneficial interest in any
         Global Security.

                 SECTION 2.7.     Replacement Securities.  If a mutilated
Security is surrendered to the Trustee or Registrar or if the Holder of a
Security claims that the Security has been lost, destroyed or wrongfully taken,
Bucyrus shall issue and the Trustee shall authenticate a replacement Security
and the Guarantors shall execute a Guarantee thereon if the requirements of
Section 8-405 of the Uniform Commercial Code are met and the Holder satisfies
any other reasonable requirements of the Trustee and Bucyrus.  Such Holder
shall furnish an indemnity bond sufficient in the judgment of Bucyrus, the
Guarantors and the Trustee to protect Bucyrus, the Guarantors, the Trustee, the
Paying Agent, the Registrar and any co-registrar from any loss which any of
them may suffer if a Security is replaced.  Bucyrus and the Trustee may charge
the Holder for their expenses in replacing a Security.

                 Every replacement Security issued pursuant to the terms of
this Section shall constitute an additional obligation of Bucyrus and the
Guarantors under this Indenture.

                 The provisions of this Section are exclusive and shall
preclude (to the extent lawful) all other rights and remedies with respect to
the replacement or payment of mutilated, destroyed, lost or stolen Securities.

                 SECTION 2.8.     Outstanding Securities.  Securities
outstanding at any time are all Securities authenticated by the Trustee except
for those canceled by it, those delivered to it for cancellation and those
described in this Section as not outstanding.  Subject to the provisions of
Section 11.6, a Security does not cease to be outstanding because Bucyrus or an
Affiliate of Bucyrus holds the security.

                 If a Security is replaced pursuant to Section 2.7, it ceases
to be outstanding unless the Trustee and Bucyrus receive proof satisfactory to
them that the replaced Security is held by a bona fide purchaser.

                 If the Paying Agent segregates and holds in trust, in
accordance with this Indenture, on a redemption date or maturity date or,
pursuant to Section 8.1(a), within 91 days prior thereto, money sufficient to
pay all principal and interest payable on that redemption or maturity date with
respect to the Securities (or portions thereof) to be redeemed or maturing, as
the case may be, then on and after such date such Securities (or portions
thereof) cease to be outstanding and on and after such redemption or maturity
date interest on them ceases to accrue.

                 SECTION 2.9.     Temporary Securities.  Until definitive
Securities are ready for delivery, Bucyrus may prepare and the Trustee shall
authenticate temporary Securities.  Temporary Securities shall be substantially
in the form of definitive Securities but may have variations that Bucyrus
considers appropriate for temporary Securities.  Without unreasonable delay,
Bucyrus shall prepare and the Trustee shall authenticate definitive Securities
and deliver them in exchange for temporary securities.

                 SECTION 2.10.    Cancellation.  Bucyrus at any time may
deliver Securities to the Trustee for cancellation.  The Registrar and the
Paying Agent shall forward to the Trustee any Securities surrendered to them
for registration of transfer, exchange or payment.  The Trustee and no one else
shall cancel all Securities surrendered for registration of transfer, exchange,
payment or cancellation and deliver such canceled Securities to Bucyrus.  The
Trustee shall from time to time provide Bucyrus a list of all Securities that
have been canceled as requested by Bucyrus.

                                      -31-

Bucyrus may not issue new Securities to replace Securities it has redeemed,
paid or delivered to the Trustee for cancellation.

                 SECTION 2.11.    Defaulted Interest.  If Bucyrus defaults in a
payment of interest on the Securities, Bucyrus shall pay defaulted interest
(plus interest on such defaulted interest to the extent lawful) in any lawful
manner in accordance with Section 4.1.  Bucyrus may pay the defaulted interest
to the persons who are Securityholders on a subsequent special record date.
Bucyrus shall fix or cause to be fixed any such special record date and payment
date to the reasonable satisfaction of the Trustee and shall promptly mail to
each Holder a notice that states the special record date, the payment date and
the amount of defaulted interest to be paid.

                 SECTION 2.12.    CUSIP Numbers.  Bucyrus in issuing the
Securities may use "CUSIP" numbers (if then generally in use), and, if so, the
Trustee shall use "CUSIP" numbers in notices of redemption as a convenience to
Holders; provided that any such notice may state that no representation is made
as to the correctness of such numbers either as printed on the Securities or as
contained in any notice of a redemption and that reliance may be placed only on
the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
Bucyrus will promptly notify the Trustee of any change in the CUSIP numbers.

                 SECTION 2.13.    Restrictive Legends.  Each Global Security
and Physical Security that constitutes a Restricted Security or is sold in
compliance with Regulation S shall bear the following legend (the "Private
Placement Legend") on the face thereof until after the second anniversary of
the later of the Issue Date and the last date on which Bucyrus or any Affiliate
of Bucyrus was the owner of such Security (or any predecessor security) (or
such shorter period of time as permitted by Rule 144(k) under the Securities
Act or any successor provision thereunder), or such longer period of time as
may be required under the Securities Act or applicable state securities laws in
the opinion of counsel for Bucyrus, unless otherwise agreed by Bucyrus and the
Holder thereof:

         securities IN DEFINITIVE FORM, THIS security MAY NOT BE TRANSFERRED
         EXCEPT AS A WHOLE BY THE DEPOSITORY TO A NOMINEE OF THE DEPOSITORY, OR
         BY ANY SUCH NOMINEE OF THE DEPOSITORY, OR BY THE DEPOSITORY OR NOMINEE
         OF SUCH SUCCESSOR DEPOSITORY OR ANY SUCH NOMINEE TO A SUCCESSOR

         DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION ("DTC"), TO AN ISSUER
         OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND

                 (a)      Transfers to Non-QIB Institutional Accredited
Investors and Non-U.S. Persons.  The following provisions shall apply with
respect to the registration of any proposed transfer of a Security constituting
a Restricted Security to any Institutional Accredited Investor which is not a
QIB or to any Non-U.S. Person:

                   (i)    the Registrar shall register the transfer of any
         Security constituting a Restricted Security whether or not such
         Security bears the Private Placement Legend, if (x) the requested
         transfer is after the second anniversary of the Issue Date ( provided,
         however , that neither Bucyrus nor any Affiliate of Bucyrus has held
         any beneficial interest in such Security, or portion thereof, at any
         time on or prior to the second anniversary of the Issue Date) or (y)
         (1) in the case of a transfer to an Institutional Accredited Investor
         which is not a QIB (excluding Non-U.S. Persons), the proposed
         transferee has delivered to the Registrar a certificate





<PAGE>   40

                                      -34-

         substantially in the form of Exhibit C hereto and any legal opinions
         and certifications required thereby or (2) in the case of a transfer to
         a Non-U.S. Person, the proposed transferor has delivered to the
         Registrar a certificate substantially in the form of Exhibit D hereto;
         and

                  (ii)    if the proposed transferor is a Participant holding a
         beneficial interest in the Global Security, upon receipt by the
         Registrar of (x) the certificate, if any, required by paragraph (i)
         above and (y) written instructions given in accordance with the
         Depository's and the Registrar's procedures,

whereupon (a) the Registrar shall reflect on its books and records the date and
(if the transfer does not involve a transfer of outstanding Physical
Securities) a decrease in the principal amount of such Global Security in an
amount equal to the principal amount of the beneficial interest in the Global
Security to be transferred, and (b) Bucyrus shall execute, the Guarantors shall
execute the Guarantees on, and the Trustee shall authenticate and deliver, one
or more Physical Securities of like tenor and amount.

                 (b)      Transfers to QIBs.  The following provisions shall
apply with respect to the registration of any proposed transfer of a Security
constituting a Restricted Security to a QIB (excluding transfers to Non-U.S.
Persons):

                   (i)    the Registrar shall register the transfer if such
         transfer is being made by a proposed transferor who has checked the
         box provided for on the form of Security stating, or has otherwise
         advised Bucyrus and the Registrar in writing, that the sale has been
         made in compliance with the provisions of Rule 144A to a transferee
         who has signed the certification provided for on the form of Security
         stating, or has otherwise advised Bucyrus and the Registrar in
         writing, that it is purchasing the Security for its own account or an
         account with respect to which it exercises sole investment discretion
         and that it and any such account is a QIB within the meaning of Rule
         144A, and is aware that the sale to it is being made in reliance on
         Rule 144A and acknowledges that it has received such information
         regarding Bucyrus as it has requested pursuant to Rule 144A or has
         determined not to request such information and that it is aware that
         the transferor is relying upon its foregoing representations in order
         to claim the exemption from registration provided by Rule 144A; and

                  (ii)    if the proposed transferee is a Participant, and the
         Securities to be transferred consist of Physical Securities which
         after transfer are to be evidenced by an interest in a Global
         Security, upon receipt by the Registrar





<PAGE>   41

                                      -35-

         of written instructions given in accordance with the Depository's and
         the Registrar's procedures, the Registrar shall reflect on its books
         and records the date and an increase in the principal amount of such
         Global Security in an amount equal to the principal amount of the
         Physical Securities to be transferred, and the Trustee shall cancel
         the Physical Securities so transferred.

                 (c)      Private Placement Legend.  Upon the transfer,
exchange or replacement of Securities not bearing the Private Placement Legend,
the Registrar shall deliver Securities that do not bear the Private Placement
Legend.  Upon the transfer, exchange or replacement of Securities bearing the
Private Placement Legend, the Registrar shall deliver only Securities that bear
the Private Placement Legend unless (i) the requested transfer is after the
second anniversary of the Issue Date (provided, however, that neither Bucyrus
nor any Affiliate of Bucyrus has held any beneficial interest in such Security,
or portion thereof, at any time prior to or on the second anniversary of the
Issue Date), or (ii) there is delivered to the Registrar an Opinion of Counsel
reasonably satisfactory to Bucyrus and the Trustee to the effect that neither
such legend nor the related restrictions on transfer are required in order to
maintain compliance with the provisions of the Securities Act.

                 (d)      General.  By its acceptance of any Security bearing
the Private Placement Legend, each Holder of such a Security acknowledges the
restrictions on transfer of such Security set forth in this Indenture and in
the Private Placement Legend and agrees that it will transfer such Security
only as provided in this Indenture.

                 The Registrar shall retain copies of all letters, notices and
other written communications received pursuant to Section 2.6 or this Section
2.14.  Bucyrus shall have the right to inspect and make copies of all such
letters, notices or other written communications at any reasonable time during
the Registrar's normal business hours upon the giving of reasonable written
notice to the Registrar.

                 (e)      Transfers of Securities Held by Affiliates.  Any
certificate (i) evidencing a Security that has been transferred to an Affiliate
of Bucyrus within two years after the Issue Date, as evidenced by a notation on
the Assignment Form for such transfer or in the representation letter delivered
in respect thereof or (ii) evidencing a Security that has been acquired from an
Affiliate (other than by an Affiliate) in a transaction or a chain of
transactions not involving any public offering, shall, until two years after
the last date on which either Bucyrus or any Affiliate of Bucyrus was an owner
of such Security, in each case, bear a legend in substantially the form set
forth in Section 2.13

hereof, unless otherwise agreed by Bucyrus (with written notice thereof to the
Trustee).

                                   ARTICLE 3

                                   REDEMPTION

                 SECTION 3.1.     Notices to Trustee.  If Bucyrus elects to
redeem Securities pursuant to paragraph 5 thereof, it shall notify the Trustee
in writing of the redemption date, the principal amount of Securities to be
redeemed and the paragraph of the Securities pursuant to which the redemption
will occur.  Bucyrus shall give each notice to the Trustee provided for in this
Section at least 45 days before the redemption date unless the Trustee consents
to a shorter period.  Such notice shall be accompanied by an Officers'
Certificate from Bucyrus to the effect that such redemption will comply with
the provisions herein.

                 SECTION 3.2.     Selection of Securities To Be Redeemed.  If
fewer than all the Securities are to be redeemed, the Trustee shall select the
Securities to be redeemed pro rata or by lot or by such other method that
complies with applicable legal and securities exchange requirements, if any,
and that the Trustee in its sole discretion shall deem to be fair and
appropriate and in accordance with methods generally used at the time of
selection by fiduciaries in similar circumstances.  The Trustee shall make the
selection from outstanding Securities not previously called for redemption.
Securities and portions of them the Trustee selects shall be in amounts of
$1,000 or a whole multiple of $1,000.  Provisions of this Indenture that apply
to Securities called for redemption also apply to portions of Securities called
for redemption.  The Trustee shall notify Bucyrus promptly of the Securities or
portions of Securities to be redeemed.  If any Security is to be redeemed in
part only, the notice of redemption relating to such Security shall state the
portion of the principal amount thereof to be redeemed.  A new Security in
principal amount equal to the unredeemed portion thereof will be issued in the
name of the Holder thereof upon cancellation of the original Security.  In the
event Bucyrus is required to make an offer to purchase  Securities pursuant to
Section 4.8 or 4.13 and the amount available for such offer is not evenly
divisible by $1,000, the Trustee shall promptly refund to Bucyrus any remaining
funds, which in no event will exceed $1,000.

                 SECTION 3.3.     Notice Of Redemption.  At least 30 days but
not more than 60 days before a date for redemption of Securities, Bucyrus shall
mail a notice of redemption by first-class mail to the registered address
appearing in the Security Register of each Holder of Securities to be redeemed.
The notice shall identify the Securities to be redeemed and shall state:





<PAGE>   43

                                      -37-


                 (1)      the redemption date;

                 (2)      the redemption price;

                 (3)      the name and address of the Paying Agent;

                 (4)      that Securities called for redemption must be
surrendered to the Paying Agent to collect the redemption price;

                 (5)      if fewer than all the outstanding Securities are to
be redeemed, the identification and principal amounts of the particular
Securities to be redeemed;

                 (6)      that, unless Bucyrus defaults in making such
redemption payment, interest on Securities (or portion thereof) called for
redemption ceases to accrue on and after the redemption date;

                 (7)      the paragraph of the Securities pursuant to which the
Securities called for redemption are being redeemed;

                 (8)      the CUSIP number, if any, printed on the Securities
being redeemed; and

                 (9)      that no representation is made as to the correctness
or accuracy of the CUSIP number, if any, listed in such notice or printed on
the Securities.

                 At Bucyrus' request, the Trustee shall give the notice of
redemption in Bucyrus' name and at Bucyrus' sole expense.  In such event,
Bucyrus shall provide the Trustee with the information required by this
Section.

                 SECTION 3.4.     Effect of Notice of Redemption.  Once notice
of redemption is mailed, Securities called for redemption become due and
payable on the redemption date and at the redemption price stated in the
notice.  Upon surrender to the Paying Agent, such Securities shall be paid at
the redemption price stated in the notice, plus accrued interest to the
redemption date.  Such notice if mailed in the manner herein provided shall be
conclusively presumed to have been given, whether or not the Holder receives
such notice.  Failure to give notice or any defect in the notice to any Holder
shall not affect the validity of the notice to any other Holder.

                 SECTION 3.5.     Deposit of Redemption Price.  Prior to 11:00
a.m. (New York City time) on the redemption date, Bucyrus shall deposit with
the Trustee or Paying Agent (or, if Bucyrus or a Subsidiary is the Paying
Agent, shall segregate and hold in trust) money sufficient to pay the
redemption price of and accrued interest (if any) on all Securities or portions
thereof to be





<PAGE>   44

                                      -38-

redeemed on that date other than Securities or portions of Securities called
for redemption which have been delivered by Bucyrus to the Trustee for
cancellation.

                 SECTION 3.6.     Securities Redeemed in Part.  Upon surrender
of a Security that is redeemed in part (with, if Bucyrus or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to Bucyrus and the Trustee duly executed by, the Holder thereof or
his attorney duly authorized in writing), Bucyrus shall execute, and the
Trustee shall authenticate and deliver to the Holder of such Security without
service charge, a new Security or Securities of any authorized denomination as
requested by such Holder, in aggregate principal amount equal to and in
exchange for the unredeemed portion of the principal of the Security so
surrendered, except that if a Global Security is so surrendered, Bucyrus shall
execute, and the Trustee shall authenticate and deliver to the Depository for
such Global Security, without service charge, a new Global Security in
denomination equal to and in exchange for the unredeemed portion of the
principal of the Global Security so surrendered.

                                   ARTICLE 4

                                   COVENANTS

                 SECTION 4.1.     Payment of Securities.  Bucyrus shall
promptly pay the principal of and interest on the Securities on the dates and
in the manner provided in the Securities and in this Indenture.  Principal and
interest shall be considered paid on the date due if on such date the Trustee
or the Paying Agent holds in accordance with this Indenture money sufficient to
pay all principal and interest then due.  Bucyrus shall pay interest on overdue
principal at 1% per annum in excess of the rate per annum set forth in the
Securities, and it shall pay interest on overdue installments of interest at
the same rate to the extent lawful.  Interest will be computed on a basis of a
360-day year of twelve 30-day months.

                 SECTION 4.2.     Corporate Existence.  Subject to Article 5
and Section 4.13, Bucyrus shall do or caused to be one, at its own cost and
expense, all things necessary to, and will cause each Restricted Subsidiary to,
preserve and keep in full force and effect the corporate or partnership
existence and rights (charter and statutory), licenses and/or franchises of
Bucyrus and each Restricted Subsidiary; provided, however, that neither Bucyrus

                 SECTION 4.3.     Maintenance of Office or Agency.  Bucyrus
shall maintain in the Borough of Manhattan the City of New York, an office or
agency (which may be an office or agency of the Trustee, Registrar or
co-Registrar), where Securities may be surrendered for registration of transfer
or exchange or for presentation for payment and where notices and demands to or
upon Bucyrus in respect of the Securities and this Indenture may be served.
Bucyrus will give prompt written notice to the Trustee of the location, and any
change in the location, of such office or agency.  If at any time Bucyrus shall
fail to maintain any such required office or agency or shall fail to furnish
the Trustee with the address thereof, such presentations, surrenders, notices
and demands may be made or served at the address of the Trustee's office in New
York City as set forth in Section 11.2.

                 Bucyrus may also from time to time designate one or more other
offices or agencies where the Securities may be presented or surrendered for
any or all such purposes and may from time to time rescind such designations;
provided, however, that no such designation or rescission shall in any manner
relieve Bucyrus of its obligation to maintain an office or agency in the
Borough of Manhattan, the City of New York, for such purposes.  Bucyrus will
give prompt written notice to the Trustee of any such designation or rescission
and of any change in the location of any such other office or agency.

                 Bucyrus hereby initially designates the Trustee's office or
agency in New York City as set forth in Section 11.2 as an agency of Bucyrus in
accordance with Section 2.3.

                 SECTION 4.4.     Payment of Taxes and Other Claims.  Bucyrus
shall, and shall cause each of its Subsidiaries to, pay or discharge or cause
to be paid or discharged, before the same shall become delinquent, (a)all
taxes, assessments and governmental charges levied or imposed upon its or its
Subsidiaries' income, profits or propertyand (b) all lawful claims for labor,
materials and supplies which, if unpaid, might by law become a Lien upon its
property; provided, however, that none of Bucyrus or its Subsidiaries shall be
required to pay or discharge or cause to be paid or discharged any such tax,
assessment, charge or claim whose amount, applicability or validity is being
contested in good faith by appropriate negotiations or proceedings and for
which disputed amounts adequate reserves have been made in accordance with
GAAP.

                 SECTION 4.5.     Future Guarantors.  Buyers shall cause each
Restricted Subsidiary other than any Foreign Subsidiary to execute and deliver
to the Trustee a supplemental indenture pursuant to which such Restricted
Subsidiary will unconditionally and irrevocably guarantee (the "Guarantees")
payment of the Securities on the same terms and conditions as those set forth
in this Indenture and the Securities.

                 SECTION 4.6.     SEC Reports.  Whether or not Bucyrus is then
subject to Section 13(a) or 15(d) of the Exchange Act, Bucyrus shall file with
the Commission, so long as the Securities are outstanding, the annual reports,
quarterly reports and other periodic reports that Bucyrus would be required to
file with the Commission pursuant to Section 13(a) or 15(d) if Bucyrus were so
subject, and such documents shall be filed with the Commission on or prior to
the respective dates (the "Required Filing Dates") by which Bucyrus would be
required so to file such documents if Bucyrus were so subject, unless, in any
case, such filing is not then permitted by the Commission.  Bucyrus will also
in any event (i) within 15 days of each Required Filing Date, (a) transmit by
mail to holders of Securities, as their names and addresses appear in the
Securities Register, without cost to such holders, and (b) file with the
Trustees copies of the annual reports, quarterly reports and other periodic
reports that Bucyrus would be required to file with the Commission pursuant to
Section 13(a) or 15(d) of the Exchange Act if Bucyrus were subject to such
Section 13(a) or 15(d), and (ii) if such filing with Commission is not then
permitted by the Commission promptly upon written request, supply copies of
such documents to any prospective holder at Bucyrus' cost.

                 SECTION 4.7.     Compliance Certificate.  Bucyrus shall
deliver to the Trustee within 120 days after the end of each fiscal year of
Bucyrus an Officers' Certificate, signers of which shall be the principal
executive, financial or accounting officer of Bucyrus, stating that in the
course of the performance by the signers of their duties as Officers of Bucyrus
they would normally have knowledge of any Default and whether or not the
signers know of any Default that occurred during such period.  If they do, the
certificate shall describe the Default, its status and what action Bucyrus is
taking or proposes to take with respect thereto.  Bucyrus also shall comply
with TIA Section 314(a)(4).

                 SECTION 4.8.     Change of Control.

                 (a)      Upon the occurrence of a Change of Control, each
Holder shall have the right to require Bucyrus to purchase all or a portion of
such Holder's Securities at a purchase price in cash equal to 101% of the
principal amount thereof, plus accrued and unpaid interest, if any, to the date
of purchase (subject to the right of Holders of record on the relevant record
date to receive interest due on an interest payment date that is on or prior to
the date fixed for redemption), in accordance with the terms contemplated in
Section 4.8(b).

                 (b)      Within 30 days following any Change of Control,
Bucyrus shall mail a notice to each Holder with a copy to the Trustee stating:

                 (1)      that a Change of Control has occurred and that such
         Holder has the right to require Bucyrus to purchase such Holder's
         Securities at the purchase price in cash equal to 101% of the
         principal amount thereof plus accrued and unpaid interest, if any, to
         the date of purchase (subject to the right of Holders of record on the
         relevant record date to receive interest on an interest payment date
         that is on or prior to the date fixed for purchase);

                 (2)      the circumstances and relevant facts and relevant
         financial information regarding such Change of Control;

                 (3)      the purchase date (which shall be no earlier than 30
         days nor later than 60 days from the date such notice is mailed); and

                 (4)      the instructions as determined by Bucyrus, consistent
         with this Section 4.8, that a Holder must follow in order to have its
         Securities purchased.

                 (c)      Holders electing to have a Security purchased will be
required to surrender the Security, together with all necessary endorsements
and other appropriate materials duly completed, to Bucyrus at the address
specified in the notice at least three Business Days prior to the purchase
date.  Holders will be entitled to withdraw their election if the Trustee or
Bucyrus receives not later than one Business Day prior to the purchase date, a
facsimile transmission or letter setting forth the name of the Holder, the
principal amount of the Security which was delivered for purchase by the Holder
as to which such notice of withdrawal is being submitted and a statement that
such Holder is withdrawing its election to have such Security purchased.

                 (d)      On the purchase date, all Securities purchased by
Bucyrus under this Section 4.8 shall be delivered to the Trustee for
cancellation, and Bucyrus shall pay the purchase price plus accrued and unpaid
interest, if any, to the Holders entitled thereto.

                 (e)      Bucyrus shall comply, to the extent applicable, with
the requirements of Section 14(e) of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Securities pursuant to
this Section 4.8.  To the extent that the provisions of any securities laws or
regulations conflict with the provisions of the covenant described hereunder,
Bucyrus shall comply with the applicable securities laws and regulations and
shall not be deemed to have breached its obligations under the covenant
described hereunder by virtue thereof.

                                      -42-

                 (f)      Notwithstanding the occurrence of a Change of
Control, Bucyrus shall not be obligated to purchase the Securities or otherwise
comply with this Section 4.8 if Bucyrus has irrevocably elected to redeem all
the Securities in accordance with paragraph 5 thereof; provided that Bucyrus
does not default in its redemption obligations pursuant to such election.

                 SECTION 4.9.     Limitation on Incurrence of Indebtedness.

                 (a)      Bucyrus shall not, and shall not permit any
Restricted Subsidiary to, Incur, directly or indirectly, any Indebtedness
except that Bucyrus or any Guarantor may Incur Indebtedness if, immediately
after giving effect to such Incurrence, the Consolidated Coverage Ratio exceeds
2.0 to 1.0.

                 (b)      The foregoing Section 4.9(a) will not prohibit
Incurrence of the following Indebtedness (collectively, "Permitted
Indebtedness"):

                 (1)      Indebtedness of Bucyrus or any Restricted Subsidiary
         Incurred pursuant to the Bank Credit Facility; provided, however,
         that, after giving effect to any such Incurrence, the aggregate
         principal amount of such Indebtedness then outstanding does not exceed
         the greater of (i) $75.0 million or (ii) the sum of (x) 60% of the net
         book value of the inventory of Bucyrus and the Restricted Subsidiaries
         and (y) 85% of the net book value of the accounts receivable of
         Bucyrus and the Restricted Subsidiaries, in each case determined on a
         consolidated basis in accordance with GAAP;

                 (2)      Indebtedness represented by the Securities (and the
         Guarantees thereof) and the Exchange Securities (and the Guarantees
         thereof), and Refinancing Indebtedness thereof;

                 (3)      Indebtedness to the extent outstanding on the Issue
         Date (other than Indebtedness described in clause (1) above or the AIP
         Bridge Loan), and Refinancing Indebtedness thereof;

                 (4)      Indebtedness of Bucyrus owed to and held by any
         Wholly Owned Subsidiary or Indebtedness of a Wholly Owned Subsidiary
         owed to and held by Bucyrus or another Wholly Owned Subsidiary;
         provided, however, that an Incurrence of Indebtedness that is not
         permitted by this clause (4) shall be deemed to have occurred upon (a)
         the transfer or other disposition of any such Indebtedness to a Person
         other than Bucyrus or a Wholly Owned Subsidiary, (b) the sale, lease,
         transfer or other disposition of shares of Capital Stock (including by
         consolidation or merger) of any Wholly Owned

                                      -43-

         Subsidiary that holds Indebtedness of Bucyrus or any other Wholly
         Owned Subsidiary to a Person other than Bucyrus or another Wholly
         Owned Subsidiary, or (c) the designation of a Wholly Owned Subsidiary
         that holds Indebtedness of Bucyrus or any other Wholly Owned
         Subsidiary as an Unrestricted Subsidiary;

                 (5)      Indebtedness of Bucyrus owed to and held by any
         Guarantor or Indebtedness of a Guarantor owed to and held by Bucyrus
         or another Guarantor; provided, however, that an Incurrence of
         Indebtedness that is not permitted by this clause (5) shall be deemed
         to have occurred upon (a) the transfer or other disposition of any
         Indebtedness to a Person other than Bucyrus or a Guarantor or (b) such
         Guarantor's ceasing to be a Guarantor;

                 (6)      Hedging Obligations consisting of Interest Rate
         Agreements and Currency Agreements entered into in the ordinary course
         of business and not for the purpose of speculation; provided, however,
         that, in the case of Currency Agreements and Interest Rate Agreements,
         such Currency Agreements and Interest Rate Agreements do not increase
         the Indebtedness of Bucyrus outstanding at any time other than as a
         result of fluctuations in foreign currency exchange rates or interest
         rates or by reason of fees, indemnities and compensation payable
         thereunder;

                 (7)      Purchase Money Indebtedness and Capital Lease
         Obligations Incurred to finance the acquisition or improvement by
         Bucyrus or a Restricted Subsidiary of any assets (including capital

                 (8)      Indebtedness of any Foreign Subsidiary Incurred for
         the working capital purposes of such Foreign Subsidiary, and
         Refinancing Indebtedness thereof, in an aggregate principal amount not
         to exceed $15.0 million at any time outstanding;

                 (9)      Indebtedness of Bucyrus or any Restricted Subsidiary
         constituting lease payments or guarantees of lease payments or similar
         obligations of a customer of Bucyrus or a Restricted Subsidiary in
         connection with a Leasing Program, and Refinancing Indebtedness
         thereof, in an aggregate principal amount not to exceed $10.0 million
         at any time outstanding; and

                 (10)     Indebtedness of Bucyrus or any Restricted Subsidiary
         in addition to that described in clauses (1) through (9) above, so
         long as the aggregate principal amount





<PAGE>   50

                                      -44-

         of all such Indebtedness incurred pursuant to this clause (10) does
         not exceed $10.0 million at any time outstanding.

                 (c)      Notwithstanding the foregoing, Bucyrus shall not, and
shall not permit any Guarantor to, Incur any Indebtedness that purports to be
by its terms (or by the terms of any agreement or instrument governing such
Indebtedness) subordinated to any other Indebtedness of Bucyrus or of such
Guarantor, as the case may be, unless such Indebtedness is also by its terms
(or by the terms of the agreement or instrument governing such Indebtedness)
made expressly subordinated to the Securities or the Guarantee of such
Guarantor, as applicable, to at least the same extent as such Indebtedness is
subordinated to such other Indebtedness of Bucyrus or such Guarantor, as
applicable.

                 SECTION 4.10.    Limitation on Restricted Payments.

                 (a)      Bucyrus shall not, and shall not permit any
Restricted Subsidiary, directly or indirectly, to declare or make a Restricted
Payment if:

                 (1)      a Default shall have occurred and be continuing (or
         would result therefrom);

                 (2)      immediately after giving effect to the proposed
         Restricted Payment, Bucyrus is not able to Incur an additional $1.00
         of Indebtedness pursuant to Section 4.9(a); or

                 (3)      the aggregate amount of such Restricted Payment
         together with all other Restricted Payments (the amount of any
         payments made in property other than cash to be valued at the fair
         market value of such property, as determined in good faith by the
         Board of Directors) declared or made since the Issue Date (other than
         any Restricted Payment described in clause (ii), (iii) or (iv) of
         Section 4.10(b)) would exceed the sum (the "Basket") of:

                          (A)     50% of the Consolidated Net Income accrued
                 during the period (treated as one accounting period) from the
                 beginning of the fiscal quarter immediately following the
                 fiscal quarter during which the Securities are originally
                 issued to the end of the most recent fiscal quarter prior to
                 the date of such Restricted Payment for which financial
                 statements are available (or, in case such Consolidated Net
                 Income accrued during such period (treated as one accounting
                 period) shall be a deficit, minus 100% of such deficit);





<PAGE>   51

                                      -45-

                          (B)     the aggregate Net Cash Proceeds received by
                 Bucyrus from the issuance or sale (other than to a Subsidiary
                 of Bucyrus) of Qualified Stock subsequent to the Issue Date;

                          (C)     the principal amount (or accreted value, if
                 less) by which Indebtedness of Bucyrus or any Restricted
                 Subsidiary is reduced on Bucyrus' balance sheet upon the
                 conversion or exchange (other than by a Subsidiary of Bucyrus)
                 subsequent to the Issue Date into Qualified Stock (less the
                 amount of any cash, or the fair value of any other property,
                 distributed by Bucyrus or any Restricted Subsidiary upon such
                 conversion or exchange); and

                          (D)     to the extent not included in the calculation
                 of the Consolidated Net Income referred to in (A), an amount
                 equal to the sum of (i) the net reduction in Investments in
                 Unrestricted Subsidiaries resulting from dividends, repayments
                 of loans or advances or other transfers of assets subsequent
                 to the Issue Date, in each case to Bucyrus or any Restricted
                 Subsidiary from Unrestricted Subsidiaries, and (ii) the
                 portion (proportionate to Bucyrus' equity interest in such
                 Subsidiary) of the fair market value of the net assets of an
                 Unrestricted Subsidiary at the time such Unrestricted
                 Subsidiary is redesignated a Restricted Subsidiary; provided,
                 however, that the foregoing sum shall not exceed, in the case
                 of any Unrestricted Subsidiary, the amount of Investments
                 previously made (and treated as a Restricted Payment) by
                 Bucyrus or any Restricted Subsidiary in such Unrestricted
                 Subsidiary;

provided, however, that the AIP Equity Contribution shall not increase the
Basket.

                 (b)      The provisions of Section 4.10(a) shall not prohibit
the following actions:  (i) dividends paid within 60 days after the date of
declaration thereof if at such date of declaration such dividend would have
been permitted under this Indenture; (ii) any repurchase, redemption,
retirement or other acquisition of Capital Stock or Subordinated Obligations of
Bucyrus made in exchange for, or out of the proceeds of the substantially
concurrent sale (other than to a Subsidiary of Bucyrus) of, Qualified Stock or,
with respect to any such Subordinated Obligations, in exchange for or out of

that such exchange or sale shall not increase the Basket; (iii) any repurchase,
redemption, retirement or other acquisition of Capital Stock of Bucyrus held by
officers,





<PAGE>   52

                                      -46-

directors and employees of Bucyrus or any Restricted Subsidiary upon such
persons' death, retirement or other termination of employment or directorship,
as the case may be; provided, however, that the aggregate amount of Restricted
Payments pursuant to this clause (iii) shall not exceed $5.0 million; and (iv)
Restricted Payments not to exceed $5.0 million in the aggregate since the Issue
Date; provided, however, that in the case of clauses (ii), (iii) and (iv), no
Default shall have occurred and be continuing or would arise therefrom.

                 SECTION 4.11.    Limitation on Liens.  Bucyrus shall not, and
shall not permit any Restricted Subsidiary to, directly or indirectly, Incur or
permit to exist any Lien (other than Permitted Liens) of any nature whatsoever
on any property of Bucyrus or any Restricted Subsidiary (including Capital
Stock of a Restricted Subsidiary), whether owned at the Issue Date or
thereafter acquired, or any income or profits therefrom or assign or convey any
right to receive income therefrom, unless the Securities and the Guarantees are
secured on an equal and ratable basis with the obligations so secured until
such time as such obligations are no longer secured by a Lien (and if the
obligations so secured are subordinated to the Securities and the Guarantees,
the Lien securing such obligations are also so subordinated at least to the
same extent).

                 SECTION 4.12.    Limitation on Transactions with Affiliates.

                 (a)      Bucyrus shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, enter into or permit to exist
any transaction or series of related transactions (including, without
limitation, the purchase, sale, lease or exchange of any property, employee
compensation arrangements or the rendering of any service) with any Affiliate
of Bucyrus (an "Affiliate Transaction") unless the terms thereof (1) are no
less favorable to Bucyrus or such Restricted Subsidiary than those that could
be obtained at the time of such transaction in arm's-length dealings with a
Person who is not such an Affiliate, (2) if such Affiliate Transaction involves
aggregate value in excess of $1.0 million in any one year, (i) are set forth in
writing, (ii) comply with clause (1), and (iii) have been approved by a
majority of the Independent Directors, and (3) if such Affiliate Transaction
involves aggregate value in excess of $5.0 million in any one year, (i) comply
with clause (2), and (ii) have been determined by a nationally recognized
investment banking, appraisal, valuation or accounting firm to be fair, from a
financial standpoint, to Bucyrus and the Restricted Subsidiaries.

                 (b)      Section 4.12(a) shall not prohibit (i) any Restricted
Payment permitted to be made pursuant to Section 4.10, (ii) any issuance of

Stock.

                 (a)      Bucyrus shall not, and shall not permit any
Restricted Subsidiary to, consummate any Asset Disposition unless (i) Bucyrus
or such Restricted Subsidiary, as the case may be, receives consideration at
the time of such Asset Disposition at least equal to the fair market value

good faith by the Board of Directors, of the assets or other property subject
to such Asset Disposition, and (ii) at least 75% of the consideration therefor
received by Bucyrus or such Restricted Subsidiary is in the form of cash or
Temporary Cash Investments.  For the purposes of this Section 4.13, the
following are deemed to be cash: (x) amount of any liabilities (other than
liabilities that are subordinated to any other Indebtedness of Bucyrus or such
Restricted Subsidiary, as the case may be) of Bucyrus or such Restricted
Subsidiary (as shown on Bucyrus' or such Restricted Subsidiary's most recent
balance sheet or in the notes thereto) that are assumed by the transferee of
any such assets or other property in such Asset Disposition, but only to the
extent that such assumption is effected on a basis under which there is no
further recourse to Bucyrus or any Restricted Subsidiary with respect to such
liabilities and (y) securities received by Bucyrus or any Restricted Subsidiary
from the transferee that are immediately converted by Bucyrus or such
Restricted Subsidiary into cash.

                 With respect to any Asset Disposition occurring on or after
the Issue Date from which Bucyrus or any Restricted Subsidiary receives Net
Available Cash, Bucyrus or such Restricted Subsidiary may within 270 days after
the date such Net Available Cash is received:  (i) apply an amount equal to
such Net Available Cash to permanently prepay, repay or purchase Indebtedness
under the Bank Credit Facility; or (ii) invest an equal amount, or the amount
not so applied pursuant to clause (i), in Additional Assets (including by means
of an Investment in Additional Assets by a Restricted Subsidiary with Net
Available Cash received by Bucyrus or another Restricted Subsidiary).  The
amount of Net Available Cash not applied pursuant to clause (ii) above shall
constitute "Excess Proceeds."  Pending application of Net Available Cash
pursuant to this provision, such Net Available Cash shall be invested in
Temporary Cash Investments.

                 If at any time the aggregate amount of Excess Proceeds not
theretofore subject to an Excess Proceeds Offer (as defined below) totals at
least $5.0 million, Bucyrus shall, not later than 10 business days after the
end of the period during which Bucyrus is required to apply such Excess
Proceeds pursuant to clause (i) of the immediately preceding paragraph (or, if
Bucyrus so elects, at any time within such period), make an offer (an "Excess
Proceeds Offer") to purchase from the holders of Securities and Other Qualified
Securities (determined on a pro rata basis according to the accreted value or
principal amount, as the case may be, of the Securities and the Other Qualified
Securities) that may be purchased out of the Excess Proceeds (rounded down to
the nearest multiple of $1,000) on such date, at a purchase price (x) in the
case of the Securities, equal to 100% of the principal amount of such
Securities, plus accrued and unpaid interest, if any, to the date of purchase
and (y) in the case of each issue of Other Qualified Securities, based on the
terms set forth in the indenture related to such issue.  Upon completion of an
Excess Proceeds Offer the amount of Excess Proceeds remaining after application
pursuant to such Excess Proceeds Offer (including payment of the purchase price
for Securities and Other Qualified Securities duly tendered) may be used by
Bucyrus for any corporate purpose (to the extent not otherwise prohibited by
this Indenture).

                 (b)      Promptly, and in any event within 30 days after
Bucyrus becomes obligated to make an Excess Proceeds Offer, Bucyrus shall be
obligated to deliver to the Trustee and send, by first-class mail to each
Holder, at the address appearing in the Securities Register, a written notice
stating that the Holder may elect to have his Securities purchased by Bucyrus
either in whole or in part (subject to prorationing as hereinafter described in
the event the Excess Proceeds Offer is oversubscribed) in integral multiples of
$1,000 of principal amount, at the applicable purchase price.  The notice,
which shall govern the terms of the





<PAGE>   55

                                      -49-

Excess Proceeds Offer, shall include such disclosures as are required by law
and shall specify (i) that the Excess Proceeds Offer is being made pursuant to
this Section 4.13; (ii) the purchase price (including the amount of accrued
interest, if any) for each Security and the purchase date not less than 30 days
nor more than 60 days after the date of such notice (the "Purchase Date");
(iii) that any Security not tendered or accepted for payment will continue to
accrue interest in accordance with the terms thereof; (iv) that, unless Bucyrus
defaults on making the payment, any Security accepted for payment pursuant to
the Excess Proceeds Offer shall cease to accrue interest on and after the
Purchase Date; (v) that Holders electing to have Securities purchased pursuant
to an Excess Proceeds Offer will be required to surrender their Securities to
the Paying Agent at the address specified in the notice at least three Business
Days prior to 5:00 p.m., New York City time, on the Purchase Date and must
complete any form letter of transmittal proposed by Bucyrus and acceptable to
the Trustee and the Paying Agent; (vi) that Holders will be entitled to
withdraw their election if the Paying Agent receives, not later than one
Business Day prior to the Purchase Date, a telex, facsimile transmission or
letter setting forth the name of the Holder, the principal amount of Securities
the Holder delivered for purchase, the Security certificate number (if any) and
a statement that such Holder is withdrawing its election to have such
Securities purchased; (vii) that if Securities in a principal amount in excess
of the aggregate principal amount which Bucyrus has offered to purchase are
tendered pursuant to the Excess Proceeds Offer, Bucyrus shall purchase
Securities on a pro rata basis among the Securities tendered (with such
adjustments as may be deemed appropriate by Bucyrus so that only Securities in
denominations of $1,000 or integral multiples of $1,000 shall be acquired);
(viii) that Holders whose Securities are purchased only in part will be issued
new Securities equal in principal amount to the unpurchased portion of the
Securities surrendered; and (ix) the instructions that Holders must follow in
order to tender their Securities.

                 (c)      Not later than the date upon which written notice of
an Excess Proceeds Offer is delivered to the Trustee as provided below, Bucyrus
shall deliver to the Trustee an Officers' Certificate as to (i) the amount of
the Excess Proceeds Offer (the "Excess Proceeds Offer Amount"), (ii) the
allocation of the Net Available Cash from the Asset Dispositions pursuant to
which such Excess Proceeds Offer is being made, and (iii) the compliance of
such allocation with the provisions of Section 4.13(a).  Upon the expiration of
the period for which the Excess Proceeds Offer remains open (the "Excess
Proceeds Offer Period"), Bucyrus shall deliver to the Trustee for cancellation
the Securities or portions thereof which have been properly tendered to and are
to be accepted by Bucyrus.  Not later than 11:00 a.m. (New York City time) on
the Purchase Date, Bucyrus shall irrevocably deposit with





<PAGE>   56

                                      -50-

the Trustee or with a paying agent (or, if Bucyrus is acting as Paying Agent,
segregate and hold in trust) an amount in cash sufficient to pay the Excess
Proceeds Offer Amount for all Securities properly tendered to and accepted by
Bucyrus.  The Trustee shall, on the Purchase Date, mail or deliver payment to
each tendering Holder in the amount of the purchase price.

                 (d)      Holders electing to have a Security purchased will be
required to surrender the Security, together with all necessary endorsements
and other appropriate materials duly completed, to Bucyrus at the address
specified in the notice at least three Business Days prior to the Purchase
Date.  Holders will be entitled to withdraw their election in whole or in part
if the Trustee or Bucyrus receives not later than one Business Day prior to the
Purchase Date, a facsimile transmission or letter setting forth the name of the
Holder, the principal amount of the Security (which shall be $1,000 or an
integral multiple thereof) which was delivered for purchase by the Holder, the
aggregate principal amount of such Security (if any) that remains subject to
the original notice of the Excess Proceeds Offer and that has been or will be
delivered for purchase by Bucyrus and a statement that such Holder is
withdrawing his election to have such Security purchased.  If at the expiration
of the Excess Proceeds Offer Period the aggregate principal amount of
Securities surrendered by Holders exceeds the Excess Proceeds Offer Amount,
Bucyrus shall select the Securities to be purchased on a pro rata basis (with
such adjustments as may be deemed appropriate by Bucyrus so that only
securities in denominations of $1,000, or integral multiples thereof, shall be
purchased).  Holders whose Securities are purchased only in part will be issued
new Securities equal in principal amount to the unpurchased portion of the
Securities surrendered.

                 (e)      A Security shall be deemed to have been accepted for
purchase at the time the Trustee, directly or through an agent, mails or
delivers payment therefor to the surrendering Holder.

                 (f)      Bucyrus shall comply, to the extent applicable, with
the requirements of Section 14(e) of the Exchange Act and any other securities
laws or regulations thereunder in the event that such Excess Proceeds are
received by Bucyrus under the covenant described hereunder and Bucyrus is
required to repurchase Securities described above.  To the extent that the
provisions of any securities laws or regulations conflict with the provisions
of the covenants described hereunder, Bucyrus shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its
obligations under the covenant described hereunder by virtue thereof.

                 SECTION 4.14.    Limitation on Dividend and Other Restrictions
Affecting Restricted Subsidiaries.  Bucyrus shall not, and shall not permit any
Restricted Subsidiary to, directly or indirectly, create or otherwise cause or
permit to exist or become effective any consensual encumbrance or consensual
restriction on the ability of any Restricted Subsidiary

                   (i)    to pay dividends or make any other distributions on
         its Capital Stock to Bucyrus or any other Restricted Subsidiary or pay
         any Indebtedness owed to Bucyrus or any other Restricted Subsidiary,

                  (ii)    to make any loans or advances to, or guarantee any

                 which was entered into on or prior to the date on which such
                 Restricted Subsidiary was acquired by Bucyrus (other than as
                 consideration in, or to provide all or any portion of the
                 funds or credit support utilized to consummate, the
                 transaction or series of related transactions pursuant to
                 which such Restricted Subsidiary became a Restricted
                 Subsidiary or was acquired by Bucyrus) and outstanding on such
                 date;

                          (C)     any encumbrance or restriction pursuant to an

                 respect to such Restricted Subsidiary contained in any such
                 refinancing agreement or amendment are no more restrictive in
                 any material respect than the

                 Subsidiary contained in such agreements;

                          (D)     any such encumbrance or restriction
                 consisting of customary non-assignment provisions in leases
                 governing leasehold interests to the extent such provisions
                 restrict the transfer of the lease or the property leased

                 the sale or disposition of the Capital Stock or assets of such
                 Restricted Subsidiary; provided, however, that such
                 restriction is applicable only to such Capital Stock or
                 assets, as applicable, and such sale or disposition otherwise
                 is permitted under Section 4.13; and

have (a) Incurred Indebtedness in an amount equal to the Attributable Debt

and is continuing (other than an Event of Default described in clause (vi) or
(vii) of Section 6.1 with respect to Bucyrus), the Trustee or the Holders of at
least 25% in principal amount of the outstanding Securities may declare the
principal of and accrued but unpaid interest on all the Securities to be due
and payable.  Upon such a declaration, such principal and interest shall be due
and payable immediately.  If an Event of Default described in clause (vi) or
(vii) of Section 6.1 occurs with respect to Bucyrus, the principal of and
interest on all the Securities will ipso facto become and be immediately due
and payable without any declaration or other act on the part of the Trustee or
any Holders of the Securities.  The Holders of a majority in aggregate
principal amount of the outstanding Securities by notice to the Trustee may
rescind an acceleration and its consequences if the rescission would not
conflict with any judgment or decree and if all existing Events of Default have
been cured or waived except nonpayment of principal or interest that has become
due solely because of acceleration.  No such rescission shall affect any
subsequent Default or impair any right consequent thereto.

                 SECTION 6.3.     Other Remedies.  If an Event of Default
occurs and is continuing, the Trustee may pursue any available remedy to
collect the payment of principal of or interest on the Securities or to enforce
the performance of any provision of the Securities or this Indenture.

                                      -57-

                 The Trustee may maintain a proceeding even if it does not
possess any of the Securities or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Holder in exercising any right or
remedy accruing upon an Event of Default shall not impair the right or remedy or
constitute a waiver of or acquiescence in the Event of Default.  No remedy is
exclusive of any other remedy.  All available remedies are, to the extent
permitted by law, cumulative.

                 SECTION 6.4.     Waiver of Past Defaults.  The Holders of a
majority in aggregate principal amount of the Securities then outstanding by
notice to the Trustee may waive any past or existing Default and its
consequences except (i) a Default in the payment of the principal of or
interest on a Security or (ii) a Default in respect of a provision that under
Section 9.2 cannot be amended without the consent of each Holder affected.
When a Default is waived, it is deemed cured, and any Event of Default arising
therefrom shall be deemed to have been cured, but no such waiver shall extend
to any subsequent or other Default or impair any consequent right.

                 SECTION 6.5.     Control by Majority.  The Holders of a
majority in principal amount of the outstanding Securities may direct the time,
method and place of conducting any proceeding for any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee.  However,
the Trustee may refuse to follow any direction that conflicts with law or this
Indenture or, subject to Section 7.1, that the Trustee determines is unduly
prejudicial to the rights of any other Holder (it being understood that the
Trustee shall have no duty to make such determination) or that would involve
the Trustee in personal liability; provided, however, that the Trustee may take
any other action deemed proper by the Trustee that is not inconsistent with
such direction.  Prior to taking any action hereunder, the Trustee shall be
entitled to indemnification from the Holders satisfactory to it in its sole
discretion against all losses and expenses caused by taking or not taking such
action.

                 SECTION 6.6.     Limitation on Suits.  A Holder may not pursue
any remedy with respect to this Indenture or the Securities unless:

                 (1)      such Holder has previously given the Trustee notice
         stating that an Event of Default is continuing;

                 (2)      Holders of at least 25% in principal amount of the
         outstanding Securities have requested the Trustee to pursue the
         remedy;

                 (3)      such Holders have offered the Trustee reasonable
         security or indemnity against any loss, liability or expense;





<PAGE>   64

                                      -58-

                 (4)      the Trustee has not complied with such request within
         60 days after the receipt thereof and the offer of security or
         indemnity; and

                 (5)      the Holders of a majority in principal amount of the
         outstanding Securities have not given the Trustee a direction
         inconsistent with such request during such 60-day period.

                 A Holder may not use this Indenture to prejudice the rights of
another Holder or to obtain a preference or priority over another Holder.

                 SECTION 6.7.     Rights of Holders to Receive Payment.
Notwithstanding any other provision of this Indenture, the right of any Holder
to receive payment of principal, premium (if any) or interest on the Securities
held by such Holder, on or after the respective due dates therefor, or to bring
suit for the enforcement of any such payment on or after such respective dates,
shall not be impaired or affected without the consent of such Holder.

                 SECTION 6.8.     Collection Suit by Trustee.  If an Event of
Default specified in Section 6.1(i) or (ii) occurs and is continuing, the
Trustee may recover judgment in its own name and as trustee of an express trust
against Bucyrus for the whole amount then due and owing (together with interest
on any unpaid interest to the extent lawful) and the amounts provided for in
Section 7.7.

                 SECTION 6.9.     Trustee May File Proofs of Claim.  The
Trustee may file such proofs of claim and other papers or documents as may be
necessary or advisable in order to have the claims of the Trustee and the
Holders allowed in any judicial proceedings relative to Bucyrus, its creditors
or its property and, unless prohibited by law or applicable regulations, may
vote on behalf of the Holders in any election of a trustee in bankruptcy or
other Person performing similar functions, and any Custodian in any such
judicial proceeding is hereby authorized by each Holder to make payments to the
Trustee and, in the event that the Trustee shall consent to the making of such
payments directly to the Holders, to pay to the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and its counsel, and any other amounts due the Trustee
under Section 7.7.

                 SECTION 6.10.    Priorities.  If the Trustee collects any
money or property pursuant to this Article 6, it shall pay out the money or
property in the following order, subject to applicable law:





<PAGE>   65

                                      -59-


                 FIRST:  to the Trustee for amounts due under Section 7.7;

                 SECOND:  to Holders for amounts due and unpaid on the
         Securities for principal and interest, ratably, without preference or
         priority of any kind, according to the amounts due and payable on the
         Securities for principal and interest, respectively; and

                 THIRD:  to Bucyrus.

                 The Trustee may, upon prior written notice to Bucyrus, fix a
record date and payment date for any payment to Holders pursuant to this
Section.  At least 15 days before such record date, Bucyrus shall mail to each
Holder and the Trustee a notice that states the record date, the payment date
and amount to be paid.

                 SECTION 6.11.    Undertaking for Costs.  In any suit for the
enforcement of any right or remedy under this Indenture or in any suit against
the Trustee for any action taken or omitted by it as Trustee, a court in its
discretion may require the filing by any party litigant in the suit of an
undertaking to pay the costs of the suit, and the court in its discretion may
assess reasonable costs, including reasonable attorneys' fees and expenses,
against any party litigant in the suit, having due regard to the merits and
good faith of the claims or defenses made by the party litigant.  This Section
does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section
6.7 or a suit by Holders of more than 10% in aggregate principal amount of the
outstanding Securities.

                                   ARTICLE 7

                                    TRUSTEE

                 SECTION 7.1.     Duties of Trustee.

                 (a)      If an Event of Default has occurred and is
continuing, the Trustee shall exercise the rights and powers vested in it by
this Indenture and use the same degree of care and skill in their exercise as a
prudent Person would exercise or use under the circumstances in the conduct of
such Person's own affairs.

                 (b)      Except during the continuance of an Event of Default:

                 (1)      the Trustee undertakes to perform such duties and
         only such duties as are specifically set forth in this





<PAGE>   66

                                      -60-

         Indenture and no implied covenants or obligations shall be read into
         this Indenture against the Trustee; and

                 (2)      in the absence of bad faith on its part, the Trustee
         may conclusively rely, as to the truth of the statements and the
         correctness of the opinions expressed therein, upon certificates or
         opinions furnished to the Trustee and conforming to the requirements
         of this Indenture.  However, in the case of any such certificates or
         opinions which by any provision hereof are specifically required to be
         furnished to the Trustee, the Trustee shall examine the certificates
         and opinions to determine whether or not they conform to the
         requirements of this Indenture.

                 (c)      The Trustee may not be relieved from liability for
its own negligent action, its own negligent failure to act or its own willful
misconduct, except that:

                 (1)      this paragraph does not limit the effect of paragraph
         (b) of this Section;

                 (2)      the Trustee shall not be liable for any error of
         judgment made in good faith by a Trust Officer unless it is proved
         that the Trustee was negligent in ascertaining the pertinent facts;
         and

                 (3)      the Trustee shall not be liable with respect to any
         action it takes or omits to take in good faith in accordance with a
         direction received by it pursuant to Sections 6.2 and 6.5 hereof.

                 (d)  Every provision of this Indenture relating to the conduct
or affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section and to the provisions of the TIA.

                 SECTION 7.2.     Rights of Trustee.  Subject to Section 7.1,

                 (a)      The Trustee may rely and shall be protected in acting
or refraining from acting upon any resolution, Officers' Certificate,
certificate, statement, instrument, opinion, report, notice, request,
direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document believed by it to be genuine and to
have been signed or presented by the proper party or parties.

                 (b)      Whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, the Trustee (unless other
evidence be herein





<PAGE>   67

                                      -61-

specifically prescribed) may, in the absence of bad faith on its part, rely
upon an Officers' Certificate.

                 (c)      Before the Trustee acts or refrains from acting, the
Trustee may consult with counsel, and the written advice of such counsel or any
Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith
and in reliance thereon.

                 (d)      The Trustee shall be under no obligation to exercise
any of the rights or powers vested in it by this Indenture at the request or
direction of any of the Holders pursuant to this Indenture, unless such Holders
shall have offered to the Trustee reasonable security or indemnity reasonable
to the Trustee against the costs, expenses and liabilities which might be
incurred by it in compliance with such request or direction.

                 (e)      Prior to the occurrence of an Event of Default
hereunder and after the cure or waiver of all Events of Default, the Trustee
shall not be bound to make any investigation into the facts or matters stated
in any resolution, Officers' Certificate, or other request, consent, order,
approval, appraisal, bond, debenture, note, coupon, security or other paper or
document unless requested in writing to do so by the Holders of not less than a
majority in aggregate principal amount of the Securities then outstanding;
provided that, if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of
such investigations, in the opinion of the Trustee, is not reasonably assured
to the Trustee by the security afforded to it by the terms of this Indenture,
the Trustee may require reasonable indemnity against such expenses or
liabilities as a condition to proceeding; the reasonable expenses of every such
examination shall be paid by Bucyrus or, if advanced by the Trustee, shall be
repaid by Bucyrus on demand.

                 (f)      The Trustee may execute any of the trusts or powers
hereunder or perform any duties hereunder either directly or by or through
agents or attorneys and the Trustee shall not be responsible for any misconduct
or negligence on the part of any agent or attorney appointed with due care by
it hereunder.

                 (g)      Whenever in the administration of this Indenture the
Trustee shall deem it desirable that a matter be proved or established prior to
taking, suffering or omitting any action hereunder, or where information is
required or necessary to be furnished by Bucyrus in order for the Trustee to
act, the Trustee (unless otherwise evidence by herein specifically prescribed),
shall not be liable for any action it takes or omits to take in good faith in
reliance upon an Officers' Certificate, or for any





<PAGE>   68

                                      -62-

action taken or omitted to be taken by it in good faith and believed by it to
be authorized or within the discretion, rights or powers conferred upon it by
this Indenture.

                 (h)      The Trustee shall not be bound to ascertain or
inquire as to the performance or observance of any covenants, conditions or
agreements on the part of Bucyrus, except as otherwise specifically set forth
in this Indenture, but the Trustee may require of Bucyrus full information and
advice as to the performance of the covenants, conditions and agreements
contained herein.

                 (i)      Except for (i) a default under Section 6.1(i),
6.1(ii) or 4.1, (ii) the failure of Bucyrus to file any financial statements,
documents or certificates specifically required to be filed with the Trustee
pursuant to the provisions of this Indenture or (iii) any other event of which
the Trustee has "actual knowledge" and which event constitutes a Default under
this Indenture, the Trustee shall not be deemed to have notice of any default
or event unless specifically notified in writing by Bucyrus or the holders of
not less than 25% in aggregate principal amount of the Securities then
outstanding; as used herein, the term "actual knowledge" means the actual fact
of knowing, without a duty to make any investigation with regard thereto.

                 (j)      The Trustee shall not be required to give any note,
bond or surety in respect of the execution of the trusts and powers under this
Indenture.

                 (k)      The permissive rights of the Trustee to perform acts
enumerated in this Indenture shall not be construed as a duty.

                 (l)      The Trustee shall not be liable for any interest on
any money received by it except as the Trustee may agree in writing with the
Company.

                 (m)      Money held in trust by the Trustee need not be
segregated from other funds except to the extent required by law.

                 SECTION 7.3.     Individual Rights of Trustee.  The Trustee in
its individual or any other capacity may become the owner or pledgee of
Securities and may otherwise deal with Bucyrus or its respective Affiliates
with the same rights it would have if it were not Trustee.  Any Paying Agent,
Registrar, co-registrar or co-paying agent may do the same with like rights.
However, the Trustee must comply with Sections 7.10 and 7.11.

                 SECTION 7.4.     Trustee's Disclaimer.  The Trustee shall not
be responsible for and makes no representation as to the validity or adequacy
of this Indenture or the Securities, it shall





<PAGE>   69

                                      -63-

not be accountable for Bucyrus' use of the proceeds from the Securities, and it
shall not be responsible for any statement of Bucyrus in this Indenture or in
any document issued in connection with the sale of the Securities or in the
Securities other than the Trustee's certificate of authentication.

                 SECTION 7.5.     Notice of Defaults.  If a Default occurs and
is continuing and if it is known to a Responsible Officer of the Trustee, the
Trustee shall mail to each Holder notice of the Default within 30 days after it
is known by a Trust Officer or written notice is received by the Trustee.
Except in the case of a Default in payment of principal of or interest on any
Security (including payments pursuant to the mandatory redemption provisions of
such Security, if any), the Trustee may withhold the notice if and so long as a
committee of its Trust Officers in good faith determines that withholding the
notice is in the interests of Holders.

                 SECTION 7.6.     Reports by Trustee to Holders.  As promptly
as practicable after each January 1 beginning with the January 1 following the
date of this Indenture, and in any event prior to March 31 in each year, the
Trustee shall mail to each Holder a brief report dated as of January 1 that
complies with TIA Section  313(a).  The Trustee also shall comply with TIA
Section  313(b).  Prior to delivery to the Holders, The Trustee shallpromptly
deliver to Bucyrus a copy of any report it delivers to Holders pursuant to this
Section 7.6.

                 SECTION 7.7.     Compensation and Indemnity.  Bucyrus shall
pay to the Trustee from time to time such reasonable compensation for its
services as Bucyrus and the Trustee shall from time to time agree in writing.
The Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust.  Bucyrus shall reimburse the Trustee upon request
for all reasonable out-of-pocket expenses incurred or made by it, including
costs of collection, in addition to such compensation for its services, except
any such expense, disbursement or advance as may arise from its negligence,
willful misconduct or bad faith.  Such expenses shall include the reasonable
compensation and expenses, disbursements and advances of the Trustee's agents,
counsel, accountants and experts.  The Trustee shall provide Bucyrus reasonable
notice of any expenditure not in the ordinary course of business.  Bucyrus
shall indemnify each of the Trustee and any predecessor Trustees against any
and all loss, damage, claim, liability or expense (including attorneys' fees
and expenses) (other than taxes applicable to the Trustee's compensation
hereunder) incurred by it in connection with the acceptance or administration
of this trust and the performance of its duties hereunder.  The Trustee shall
notify Bucyrus promptly of any claim for which it may seek indemnity.  Failure
by the Trustee to so notify Bucyrus shall not relieve Bucyrus of its





<PAGE>   70

                                      -64-

obligations hereunder.  Bucyrus shall defend the claim and the Trustee shall
cooperate in the defense of such claim.  The Trustee may have separate counsel
at its own expense.  If, however, representation in any defense by Bucyrus and
its counsel would in the opinion of counsel to the Trustee create a conflict of
interest, Bucyrus shall pay the expense of separate counsel to the Trustee.
Bucyrus need not reimburse any expense or indemnify against any loss, liability
or expense incurred by the Trustee through the Trustee's own willful
misconduct, negligence or bad faith.  Bucyrus need not pay for any settlement
made without its written consent.

                 To secure Bucyrus' payment obligations in this Section, the
Trustee shall have a lien prior to the Securities on all money or property held
or collected by the Trustee other than money or property held in trust to pay
principal of and interest on particular Securities.


                 Bucyrus' payment obligations pursuant to this Section shall
survive the discharge of this Indenture and the resignation or removal of the
Trustee.  When the Trustee incurs expenses after the occurrence of an Event of
Default specified in Section 6.1(vi) or (vii) with respect to Bucyrus, the
expenses are intended to constitute expenses of administration under the
Bankruptcy Law.

                 SECTION 7.8.     Replacement of Trustee.  The Trustee may
resign at any time upon 30 days notice to Bucyrusby so notifying the Company.
The Holders of a majority in principal amount of the outstanding Securities may
remove the Trustee by so notifying the Trustee and may appoint a successor
Trustee.  Bucyrus shall remove the Trustee if:

                 (1)      the Trustee fails to comply with Section 7.10;

                 (2)      the Trustee is adjudged bankrupt or insolvent;

                 (3)      a receiver or other public officer takes charge of
                          the Trustee or its property; or

                 (4)      the Trustee otherwise becomes incapable of acting.

                 If the Trustee resigns, is removed by Bucyrus or by the
Holders of a majority in principal amount of the outstanding Securities and
such Holders do not reasonably promptly appoint a successor Trustee, or if a
vacancy exists in the office of Trustee for any reason (the Trustee in such
event being referred to herein as the retiring Trustee), Bucyrus shall promptly
appoint a successor Trustee.

                 A successor Trustee shall deliver a written acceptance of its
appointment to the retiring Trustee and to Bucyrus.





<PAGE>   71

                                      -65-

Thereupon the resignation or removal of the retiring Trustee shall become
effective, and the successor Trustee shall have all the rights, powers and
duties of the Trustee under this Indenture.  The successor Trustee shall mail a
notice of its succession to Holders.  The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, subject
to the lien provided for in Section 7.7.

                 If a successor Trustee does not take office within 60 days
after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the outstanding Securities may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

                 If the Trustee fails to comply with Section 7.10, any Holder
may petition any court of competent jurisdiction for the removal of the Trustee
and the appointment of a successor Trustee.

                 Notwithstanding the replacement of the Trustee pursuant to
this Section, Bucyrus' obligations under Section 7.7 shall continue for the
benefit of the retiring Trustee.

                 SECTION 7.9.     Successor Trustee by Merger.  If the Trustee
consolidates with, merges or converts into, or transfers all or substantially
all its corporate trust business or assets to, another corporation or banking
association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee, so long as such corporation is
eligible under this Article 7 and TIA Section  310(a).

                 In case at the time such successor or successors by merger,
conversion or consolidation to the Trustee shall succeed to the trusts created
by this Indenture any of the Securities shall have been authenticated but not
delivered, any such successor to the Trustee may adopt the certificate of
authentication of any predecessor trustee, and deliver such Securities so
authenticated; and in case at that time any of the Securities shall not have
been authenticated, any successor to the Trustee may authenticate such
Securities either in the name of any predecessor hereunder or in the name of
the successor to the Trustee; and in all such cases such certificates shall
have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have.

                 SECTION 7.10.    Eligibility; Disqualification.  The Trustee
 shall at all times satisfy the requirements of TIA Section 310(a).  The
 Trustee shall have a combined capital and surplus of at least $50,000,000 as
 set forth in its most recent published annual report
of condition.  The Trustee shall comply with TIA Section  310(b); provided,
however, that there shall be excluded from the operation of TIA Section
310(b)(1) any indenture or indentures under





<PAGE>   72

                                     -66-

which other securities or certificates of interest or participation in other
securities of Bucyrus are outstanding if the requirements for such exclusion
set forth in TIA Section  310(b)(1) are met.

                 SECTION 7.11.    Preferential Collection of Claims Against
Bucyrus.  The Trustee shall comply with TIA Section  311(a), excluding any
creditor relationship listed in TIA Section  311(b).  A Trustee who has
resigned or been removed shall be subject to TIA Section
 311(a) to the extent indicated.

                                   ARTICLE 8

                       DISCHARGE OF INDENTURE; DEFEASANCE

                 SECTION 8.1.     Discharge of Liability on Securities;
Defeasance.

                 (a)      When (i) Bucyrus delivers to the Trustee all
outstanding Securities (other than Securities replaced pursuant to Section 2.7)
for cancellation or (ii) all outstanding Securities have become due and
payable, whether at maturity or as a result of the mailing of a notice of
redemption pursuant to Article 3 hereofor the Securities will become due and
payable at their Maturity within 91 days, or the securities are to be called
for redemption within 91 days under arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the name, and at the
expense, of the Company, and Bucyrus irrevocably deposits with the Trustee
funds sufficient to pay at maturity or upon redemption all outstanding
Securities, including interest thereon, and if in either case Bucyrus pays all
other sums payable hereunder by Bucyrus, then the Indenture shall, subject to
Section 8.1(c), cease to be of further effect.  The Trustee shall acknowledge
satisfaction and discharge of this Indenture on demand of Bucyrus accompanied
by an Officers' Certificate and an Opinion of Counsel that all conditions
precedent provided for herein relating to satisfaction and discharge of this
Indenture have been complied with and at the cost and expense of Bucyrus.

                 (b)      Subject to Sections 8.1(c) and 8.2, Bucyrus at any
time may terminate (i) all its obligations under the Securities and this
Indenture ("legal defeasance option") or (ii) its obligations under Sections
4.4 through 4.16, inclusive and the operation of Sections 6.1(iii), 6.1(iv),
6.1(v), 6.1(vi) (but only with respect to Significant Restricted Subsidiaries)
and 6.1(vii) (but only with respect to Significant Restricted Subsidiaries),
6.1(viii) and 5.1(iii) and 5.1(iv) ("covenant defeasance option").  Bucyrus may
exercise its legal defeasance option notwithstanding its prior exercise of its
covenant defeasance option.





<PAGE>   73

                                      -67-

                 If Bucyrus exercises its legal defeasance option, payment of
the Securities may not be accelerated because of an Event of Default.  If
Bucyrus exercises its covenant defeasance option, payment of the Securities may
not be accelerated due to a failure to comply with any of Sections 4.4 through
4.16, inclusive, or the operation of Sections 6.1(iii), 6.1(iv), 6.1(v),
6.1(vi) (but only with respect to Significant Restricted Subsidiaries),
6.1(vii) (but only with respect to a Significant Subsidiaries), or 6.1(viii).
If Bucyrus exercises its legal defeasance option or its covenant defeasance
option, each Guarantor will be released from all of its obligations under
Article 11.

                 Upon satisfaction of the conditions set forth herein and upon
request of Bucyrus, the Trustee shall acknowledge in writing the discharge of
those obligations that Bucyrus terminates.

                 (c)      Notwithstanding clauses (a) and (b) above, Bucyrus'
obligations in Sections 2.3, 2.4, 2.5, 2.6, 2.7, 7.7, 7.8, 8.3, 8.4, 8.5 and
8.6 shall survive until the Securities have been paid in full.  Thereafter,
Bucyrus' obligations in Sections 7.7, 8.4 and 8.5 shall survive.

                 SECTION 8.2.     Conditions to Defeasance.  Bucyrus may
exercise its legal defeasance option or its covenant defeasance option only if:

                 (1)      Bucyrus irrevocably deposits in trust (the
         "defeasance trust") with the Trustee money or U.S. Government
         Obligations which through the scheduled payment of principal and
         interest in respect thereof in accordance with their terms will
         provide cash (without reinvestment) at such times and in such amounts
         as will be sufficient to pay principal and interest on the Securities
         (except Securities replaced pursuant to Section 2.7) to redemption or
         maturity, as the case may be;

                 (2)      Bucyrus delivers to the Trustee a certificate from a
         nationally recognized firm of independent accountants expressing their
         opinion that the payments of principal and interest when due and
         without reinvestment on the deposited U.S. Government Obligations plus
         any deposited money without investment will provide cash at such times
         and in such amounts as will be sufficient to pay principal and
         interest when due on all outstanding Securities (except Securities
         replaced pursuant to Section 2.7) to maturity or redemption, as the
         case may be;

                 (3)      91 days pass after the deposit is made and during the
         91-day period no Default specified in Section 6.1(vi) or





<PAGE>   74

                                      -68-

         (vii) with respect to Bucyrus occurs which is continuing at the end of
         the period;

                 (4)      no default exists under any Indebtedness of Bucyrus
         or any Restricted Subsidiary;

                 (5)      Bucyrus delivers to the Trustee an Opinion of Counsel
         to the effect that the trust resulting from the deposit does not
         constitute, or is qualified as, a regulated investment company under
         the Investment Company Act of 1940;

                 (6)      Bucyrus shall have delivered to the Trustee an
         Opinion of Counsel stating that the Holders will not recognize income,
         gain or loss for Federal income tax purposes as a result of such
         deposit and defeasance and will be subject to Federal income tax on
         the same amounts and in the same manner and at the same times as would
         have been the case if such deposit and defeasance had not occurred
         (and, in the case of legal defeasance only, such Opinion of Counsel
         must be based on a ruling of the Internal Revenue Service or change in
         applicable Federal income tax law);

                 (7)      Bucyrus delivers to the Trustee an Officers'
         Certificate and an Opinion of Counsel, each stating that all
         conditions precedent to the defeasance and discharge of the Securities
         as contemplated by this Article 8 have been complied with; and

                 (8)      Bucyrus shall have paid or duly provided for payment
         under terms mutually satisfactory to Bucyrus and the Trustee all
         amounts then due to the Trustee pursuant to Section 7.7 hereof.

                 Opinions of Counsel required to be delivered under this
Section may have qualifications customary for opinions of the type required and
counsel delivering such Opinions of Counsel may rely on certificates of Bucyrus
or government or other officials customary for opinions of the type required,
including certificates certifying as to matters of fact.

                 Before or after a deposit, Bucyrus may make arrangements
satisfactory to the Trustee for the redemption of Securities at a future date
in accordance with Article 3.

                 SECTION 8.3.     Application of Trust Money.  The Trustee
shall hold in trust money or U.S. Government Obligations deposited with it
pursuant to this Article Eight.  It shall apply the deposited money and the
money from U.S. Government Obligations either directly or through the Paying
Agent (including Bucyrus acting as its own Paying Agent as the Trustee may
determine) and





<PAGE>   75

                                      -69-

in accordance with this Indenture to the payment of principal of and interest
on the Securities.

                 SECTION 8.4.     Repayment to Bucyrus.  The Trustee and the
Paying Agent shall notify Bucyrus of any excess money or Securities held by
them at any time and shall promptly turn over to Bucyrus upon request any
excess money or securities held by them at any time.

                 Subject to any applicable abandoned property law, the Trustee
and the Paying Agent shall pay to Bucyrus upon written request any money held
by them for the payment of principal or interest that remains unclaimed for two
years, and, thereafter, Holders entitled to the money must look to Bucyrus for
payment as general creditors.

                 SECTION 8.5.     Indemnity for Government Obligations.
Bucyrus shall pay and shall indemnify the Trustee against any tax, fee or other
charge imposed on or assessed against deposited U.S. Government Obligations or
the principal and interest received on such U.S.  Government Obligations other
than any such tax, fee or other charge which by law is for the account of the
Holders of the defeased Securities; provided that the Trustee shall be entitled
to charge any such tax, fee or other charge to such Holder's account.

                 SECTION 8.6.     Reinstatement.  If the Trustee or Paying
Agent is unable to apply any money or U.S. Government Obligations in accordance
with this Article Eight by reason of any legal proceeding or by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application, Bucyrus' obligations under this
Indenture and the Securities and the Guarantors' obligations under this
Indenture and the Guarantees shall be revived and reinstated as though no
deposit had occurred pursuant to this Article Eight until such time as the
Trustee or Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article Eight; provided, however, that, (a)
if Bucyrus has made any payment of interest on or principal of any Securities
following the reinstatement of their obligations, Bucyrus shall be subrogated
to the rights of the Holders of such Securities to receive such payment from
the money or U.S. Government Obligations held by the Trustee or Paying Agent
and (b) unless otherwise required by any legal proceeding or any order or
judgment of any court or governmental authority, the Trustee or Paying Agent
shall return all such money and U.S.  Government Obligations to Bucyrus
promptly after receiving a written request therefor at any time, if such
reinstatement of Bucyrus' obligations has occurred and continues to be in
effect.



                                  ARTICLE 9

<PAGE>   76

                                      -70-



                             AMENDMENTS AND WAIVERS

                 SECTION 9.1.     Without Consent of Holders.  Bucyrus and the
Trustee may amend this Indenture or the Securities without notice to or consent
of any Holder:

                 (1)      to cure any ambiguity, defect or inconsistency;

                 (2)      to provide for the assumption by a successor
         corporation of the obligations of Bucyrus under this Indenture in the
         event of any transaction in compliance with Article 5 in which Bucyrus
         is not the Surviving Person;

                 (3)      to provide for uncertificated Securities in addition
         to or in place of certificated Securities; provided, however, that the
         uncertificated Securities are issued in registered form for purposes
         of Section 163(f) of the Code or in a manner such that the
         uncertificated Securities are as described in Section 163(f)(2)(B) of
         the Code;

                 (4)      to add Guarantees with respect to the Securities;

                 (5)      to release Guarantors when permitted by this
         Indenture;

                 (6)      to secure the Securities;

                 (7)      to add to the covenants of Bucyrus for the benefit of
         the Holders or to surrender any right or power herein conferred upon
         Bucyrus;

                 (8)      to make any change that does not adversely affect the
         rights of any Holder; or

                 (9)      to comply with any requirements of the SEC in
         connection with the qualification of this Indenture under the TIA.

                 After an amendment under this Section becomes effective,
Bucyrus shall mail to Holders a notice briefly describing such amendment.  The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this section.

                 SECTION 9.2.     With Consent of Holders.  Bucyrus and the
Trustee may amend this Indenture or the Securities with the consent of the
Holders of a majority in principal amount of the Securities then outstanding
(including consents obtained in connection with a tender offer or exchange for
the Securities) and any past default or compliance with any provisions may also
be waived with the consent of the Holders of a majority in principal





<PAGE>   77

                                      -71-

amount of the Securities then outstanding.  However, without the consent of
each Holder of outstanding Security affected thereby, no amendment may:

                 (1)      reduce the principal amount of Securities whose
         Holders must consent to an amendment, supplement or waiver;

                 (2)      reduce the principal of or change the fixed maturity
         of any Security, or alter the provisions with respect to the
         redemption or repurchase provisions of any Security or this Indenture
         in a manner adverse to the holders of the Securities (other than the
         provisions of this Indenture relating to any offer to purchase
         required under Section 4.8 or 4.13);

                 (3)      reduce the rate of or change the time for payment of
         interest on any Security;

                 (4)      waive a Default in the payment of principal or
         interest on, the Securities (except that holders of at least a
         majority in aggregate principal amount of the then outstanding
         Securities may (x) rescind an acceleration of the Securities that
         resulted from a non-payment default and (y) waive the payment default
         that resulted from such acceleration);

                 (5)      make any Security payable in money other than that
         stated in the Securities;

                 (6)      make any change in the provisions of this Indenture
         relating to waivers of past Defaults or the rights of holders of
         Securities to receive payments of principal of or interest on, the
         Securities;

                 (7)      waive a redemption payment with respect to any
         Security;

                 (8)      release any Guarantor from its Guarantee except in 
         compliance with this Indenture; or

                 (9)      make any change in the foregoing amendment and waiver
         provisions;

provided, further, however, that no such modification or amendment may, without
the consent of the holders of two-thirds of the aggregate principal amount of
Securities affected thereby, modify any of the provisions (including the
definitions thereto) under Section 4.8 in a manner materially adverse to the
Holders.

                 It shall not be necessary for the consent of the Holders under
this Section to approve the particular form of any





<PAGE>   78

                                      -72-

proposed amendment.  It is sufficient if such consent approves the substance of
the proposed amendment.

                 After an amendment under this Section becomes effective,
Bucyrus shall mail to Holders a notice briefly describing such amendment.  The
failure to give such notice to all Holders, or any defect therein, shall not
impair or affect the validity of an amendment under this Section.

                 SECTION 9.3.     Compliance with Trust Indenture Act.  Every
amendment to this Indenture or the Securities shall comply with the TIA as then
in effect.

                 SECTION 9.4.     Revocation and Effect of Consents and
Waivers.  A consent to an amendment or a waiver by a Holder of a Security shall
bind the Holder and every subsequent Holder of that Security or portion of the
Security that evidences the same debt as the consenting Holder's Security, even
if notation of the consent or waiver is not made on the Security.  An amendment
or waiver becomes effective once the requisite number of consents are received
by Bucyrus or the Trustee.  After an amendment or waiver becomes effective, it
shall bind every Holder.
Bucyrus may, but shall not be obligated to, fix a record date for the purpose
of determining the Holders entitled to give their consent or take any other
action described above or required or permitted to be taken pursuant to this
Indenture.  If a record date is fixed, then notwithstanding the immediately
preceding paragraph, those Persons who were Holders at such record date (or
their duly designated proxies), and only those Persons, shall be entitled to
give such consent or to revoke any consent previously given or to take any such
action, whether or not such Persons continue to be Holders after such record
date.  No such consent shall be valid or effective for more than 120 days after
such record date.

                 SECTION 9.5.     Notation on or Exchange of Securities.  If an
amendment changes the terms of a Security, the Trustee may require the Holder
of the Security to deliver it to the Trustee.  The Trustee may place an
appropriate notation on the Security regarding the changed terms and return it
to the Holder.

                 Alternatively, if Bucyrus or the Trustee so determines,
Bucyrus in exchange for the Security shall issue and the Trustee shall
authenticate a new Security that reflects the changed terms.  Failure to make
the appropriate notation or to issue a new Security shall not affect the
validity of such amendment.

                 SECTION 9.6.     Trustee to Sign Amendments.  The Trustee
shall sign any amendment authorized pursuant to this Article 9 (other than
Section 9.1(4)) if the amendment does not adversely affect the rights, duties,
liabilities or immunities of the





<PAGE>   79

                                      -73-

Trustee.  If it does, the Trustee may but need not sign it.  In signing such
amendment the Trustee shall be entitled to receive indemnity reasonably
satisfactory to it and to receive, and (subject to Section 7.1) shall be fully
protected in relying upon, an Officers' Certificate and an Opinion of Counsel
stating that such amendment complies with the provisions of Article 9 of this
Indenture.

                                   ARTICLE 10

                                   GUARANTEES

                 SECTION 10.1.    Guarantees.  Each Guarantor hereby
unconditionally and irrevocably guarantees, jointly and severally, to each
Holder and to the Trustee and its successors and assigns as primary obligor and
not merely as a surety, on an unsecured senior basis the performance and
punctual payment when due, whether at Stated Maturity, by acceleration or
otherwise, of all obligations of Bucyrus under this Indenture and the
Securities whether for payment of principal of or interest on the Securities,
expenses, indemnification or otherwise (all such obligations guaranteed by the
Guarantors being herein called the "Guaranteed Obligations").  The Guarantors
will agree to pay, in addition to the amount stated above, any and all expenses
(including reasonable counsel fees and expenses) incurred by the Trustee or the
Holders in enforcing any rights under the Guarantees.  Each Guarantor further
agrees that the Guaranteed Obligations may be extended or renewed, in whole or
in part, without notice or further assent from such Guarantor and that such
Guarantor will remain bound under this Article 10 notwithstanding any extension
or renewal of any Guaranteed Obligation.

                 Each Guarantor waives presentation to, demand of, payment from
and protest to Bucyrus of any of the Guaranteed Obligations and also waives
notice of protest for nonpayment.  Each Guarantor waives notice of any default
under the Securities or the Guaranteed Obligations.  The obligations of each
Guarantor hereunder shall not be affected by (a) the failure of any Holder or
the Trustee to assert any claim or demand or to enforce any right or remedy
against Bucyrus or any other Person under this Indenture, the Securities or any
other agreement or otherwise; (b) any extension or renewal of any thereof; (c)
any rescission, waiver, amendment or modification of any of the terms or
provisions of this Indenture, the Securities or any other agreement; (d) the
release of any security held by any Holder or the Trustee for the Guaranteed
Obligations or any of them; (e) the failure of any Holder or the Trustee to
exercise any right or remedy against any other guarantor of the Guaranteed
Obligations; or (f) any change in the ownership of such Guarantor.





<PAGE>   80

                                      -74-

                 Each Guarantor further agrees that its Subsidiary Guarantee
herein constitutes a guarantee of payment, performance and compliance when due
(and not a guarantee of collection) and waives any right to require that any
resort be had by any Holder or the Trustee to any security held for payment of
the Guaranteed Obligations.

                 Except as expressly set forth in Sections 8.2, 10.2 and 10.6,
the obligations of each Guarantor hereunder shall not be subject to any
reduction, limitation, impairment or termination for any reason, including any
claim of waiver, release, surrender, alteration or compromise, and shall not be
subject to any defense of setoff, counterclaim, recoupment or termination
whatsoever or by reason of the invalidity, illegality or unenforceability of
the Guaranteed Obligations or otherwise.  Without limiting the generality of
the foregoing, the obligations of each Guarantor herein shall not be discharged
or impaired or otherwise affected by the failure of any Holder or the Trustee
to assert any claim or demand or to enforce any remedy under this Indenture,
the Securities or any other agreement, by any waiver or modification of any
thereof, by any default, failure or delay, willful or otherwise, in the
performance of the Guaranteed Obligations, or by any other act or thing or
omission or delay to do any other act or thing which may or might in any manner
or to any extent vary the risk of such Guarantor or would otherwise operate as
a discharge of such Guarantor as a matter of law or equity.

                 Each Guarantor further agrees that its Guarantee herein shall
continue to be effective or be reinstated, as the case may be, if at any time
payment, or any part thereof, of any Guaranteed Obligation is rescinded or must
otherwise be restored by any Holder or the Trustee upon the bankruptcy or
reorganization of Bucyrus or otherwise.

                 In furtherance of the foregoing and not in limitation of any
other right which any Holder or the Trustee has at law or in equity against any
Guarantor by virtue hereof, upon the failure of Bucyrus to pay any Guaranteed
Obligation when and as the same shall become due, whether at maturity, by
acceleration, by redemption or otherwise, or to perform or comply with any
Guaranteed Obligation, each Guarantor hereby promises to and will, upon receipt
of written demand by the Trustee, forthwith pay, or cause to be paid, in cash,
to the Holders or the Trustee an amount equal to the sum of (i) the unpaid
amount of such Guaranteed Obligations, (ii) accrued and unpaid interest on such
Guaranteed Obligations (but only to the extent not prohibited by law) and (iii)
all other monetary Guaranteed Obligations of Bucyrus to the Holders and the
Trustee.

                 Each Guarantor agrees that it shall not be entitled to any
right of subrogation in respect of any Guaranteed Obligations





<PAGE>   81

                                      -75-

guaranteed hereby until payment in full of all Guaranteed Obligations.  Each
Guarantor further agrees that, as between it, on the one hand, and the Holders
and the Trustee, on the other hand, (x) the maturity of the Guaranteed
Obligations hereby may be accelerated as provided in Article 6 for the purposes
of such Guarantor's Guarantee herein, notwithstanding any stay, injunction or
other prohibition preventing such acceleration in respect of the Guaranteed
Obligations, and (y) in the event of any declaration of acceleration of
Guaranteed Obligations as provided in Article 6, the Obligations (whether or
not due and payable) shall forthwith become due and payable by such Guarantor
for the purposes of this Section.

                 Each Guarantor also agrees to pay any and all costs and
expenses (including reasonable attorneys' fees) incurred by the Trustee or any
Holder in enforcing any rights under this Section.

                 SECTION 10.2.    Limitation on Liability.  Any term or
provision of this Indenture to the contrary notwithstanding, the maximum
aggregate amount of the obligations guaranteed hereunder by any Guarantor shall
not exceed the maximum amount that can be hereby guaranteed without rendering
this Indenture, as it relates to such Guarantor, voidable under applicable law
relating to fraudulent conveyance or fraudulent transfer or similar laws
affecting the rights of creditors generally.  To effectuate the foregoing
intention, the obligations of each Guarantor shall be limited to the maximum
amount as will, after giving effect to all other contingent and fixed
liabilities of such Guarantor and after giving effect to any collections from
or payments made by or on behalf of any other Guarantor in respect of the
obligations of such other Guarantor under its Guarantee or pursuant to its
contribution obligations hereunder, result in the obligations of such Guarantor
under its Guarantee not constituting a fraudulent conveyance or fraudulent
transfer under federal, state or foreign law.  Each Guarantor that makes a
payment or distribution under a Guarantee shall be entitled to a contribution
from each other Guarantor in an amount based on the consolidated net worth of
each Guarantor.

                 SECTION 10.3.    Successors and Assigns.  This Article Ten
shall be binding upon each Guarantor and its successors and assigns and shall
inure to the benefit of the successors and assigns of the Trustee and the
Holders and, in the event of any transfer or assignment of rights by any Holder
or the Trustee, the rights and privileges conferred upon that party in this
Indenture and in the Securities shall automatically extend to and be vested in
such transferee or assignee, all subject to the terms and conditions of this
Indenture.

                 SECTION 10.4.    No Waiver.  Neither a failure nor a delay on
the part of either the Trustee or the Holders in





<PAGE>   82

                                      -76-

exercising any right, power or privilege under this Article 11 shall operate as
a waiver thereof, nor shall a single or partial exercise thereof preclude any
other or further exercise of any right, power or privilege.  The rights,
remedies and benefits of the Trustee and the Holders herein expressly specified
are cumulative and not exclusive of any other rights, remedies or benefits
which either may have under this Article Ten at law, in equity, by statute or
otherwise.

                 SECTION 10.5.    Modification.  No modification, amendment or
waiver of any provision of this Article Ten, nor the consent to any departure
by any Guarantor therefrom, shall in any event be effective unless the same
shall be in writing and signed by the Trustee, and then such waiver or consent
shall be effective only in the specific instance and for the purpose for which
given.  No notice to or demand on any Guarantor in any case shall entitle such
Guarantor to any other or further notice or demand in the same, similar or
other circumstances.

                 SECTION 10.6.    Release of Guarantor.  A Guarantor may, by
execution and delivery to the Trustee of a supplemental indenture satisfactory
to the Trustee, be released from its Guarantee upon the sale of all of its
Capital Stock, or all or substantially all of the assets of the applicable
Guarantor, to any Person that is not a Subsidiary of Bucyrus, if such sale is
made in compliance with this Indenture.

                 SECTION 10.7.    Execution of Supplemental Indenture for
Future Guarantors.  Each Subsidiary which is required to become a Guarantor
pursuant to Section 4.5 shall, and Bucyrus shall cause each such Subsidiary to,
promptly execute and deliver to the Trustee a supplemental indenture in the
form of Exhibit F hereto pursuant to which such Subsidiary shall become a
Guarantor under this Article Ten and shall guarantee the Guaranteed
Obligations.  Concurrently with the execution and delivery of such supplemental
indenture, Bucyrus shall deliver to the Trustee an Opinion of Counsel to the
effect that such supplemental indenture has been duly authorized, executed and
delivered by such Subsidiary and that, subject to the application of
bankruptcy, insolvency, moratorium, fraudulent conveyance or transfer and other
similar laws relating to creditors' rights generally and to the principles of
equity, whether considered in a proceeding at law or in equity, the Guarantee
of such Guarantor is a valid and legally binding obligation of such Guarantor,
enforceable against such Guarantor in accordance with its terms.

provision of this Indenture limits, qualifies or conflicts with another
provision which is required to be included in this Indenture by the TIA, the
required provision shall control.  If this Indenture excludes any provision of

be in writing and delivered in person, by overnight courier or facsimile (if to

                 Bucyrus or the Trustee by notice to the other may designate

sufficiently given if so sent within the time prescribed.

                 Failure to send a notice or communication to a Holder or any
defect in it shall not affect its sufficiency with respect to other Holders.
If a notice or communication is sent in the manner provided above, it is duly
given, whether or not the addressee receives it.

                 Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice.

                 SECTION 11.3.    Communication by Holders with Other Holders.

respect to their rights under this Indenture or

                                      -78-

the Securities.  Bucyrus, the Trustee, the Registrar and anyone else shall have
the protection of TIA Section  312(c).

                 SECTION 11.4.    Certificate and Opinion as to Conditions
Precedent.  Upon any request or application by Bucyrus to the Trustee to take
or refrain from taking any action under this Indenture, Bucyrus shall furnish
to the Trustee to the extent required by the TIA or this Indenture:

                 (1)  an Officers' Certificate (which in connection with the
         original issuance of the Securities need only be executed by one
         Officer for Bucyrus) in form and substance reasonably satisfactory to
         the Trustee stating that, in the opinion of the signers, all
         conditions precedent, if any, provided for in this Indenture relating
         to the proposed action have been complied with; and

                 (2)      an Opinion of Counsel in form and substance
         reasonably satisfactory to the Trustee stating that, in the opinion of
         such counsel, all such conditions precedent have been complied with.

                 SECTION 11.5.    Statements Required in Certificate or
Opinion.  Each certificate or opinion with respect to compliance with a
covenant or condition provided for in this Indenture shall include:

                 (1)      a statement that the individual making such
         certificate or opinion has read such covenant or condition;

                 (2)      a brief statement as to the nature and scope of the
         examination or investigation upon which the statements or opinions
         contained in such certificate or opinion are based;

                 (3)      a statement that, in the opinion of such individual,
         he has made such examination or investigation as is necessary to
         enable him to express an informed opinion as to whether or not such
         covenant or condition has been complied with; and

                 (4)      a statement as to whether or not, in the opinion of
         such individual, such covenant or condition has been complied with;
         provided, that an Opinion of Counsel can rely as to matters of fact on
         an Officers' Certificate or a certificate of a public official.

                 SECTION 11.6.    When Securities Disregarded.  In determining
whether the Holders of the required principal amount of Securities have
concurred in any direction, waiver or consent, Securities owned by Bucyrus or
by any Person directly or indirectly controlling or controlled by or under
direct or





<PAGE>   85

                                      -79-

indirect common control with Bucyrus shall be disregarded and deemed not to be
outstanding, except that, for the purpose of determining whether the Trustee
shall be protected in relying on any such direction, waiver or consent, only
Securities which the Trustee actually knows are so owned shall be so
disregarded.  Also, subject to the foregoing, only Securities outstanding at
the time shall be considered in any such determination.

                 SECTION 11.7.    Rules by Trustee, Paying Agent and Registrar.
The Trustee may make reasonable rules for action by or a meeting of Holders.
The Trustee shall provide Bucyrus reasonable notice of such rules; provided
that neither prior notice to the Company of such rules nor prior approval by
the Company of such rules shall be a requirement for their effectiveness.  The
Registrar and the Paying Agent may make reasonable rules for their functions.

                 SECTION 11.8.    Legal Holidays.  If a payment date is a Legal
Holiday, payment shall be made on the next succeeding day that is not a Legal
Holiday, and no interest shall accrue for the intervening period.  If a regular
record date is a Legal Holiday, the record date shall not be affected.

                 SECTION 11.9.    Governing Law.  This Indenture and the
Securities shall be governed by, and construed in accordance with, the laws of
the State of New York without giving effect to applicable principles of
conflict of laws to the extent that the application of the laws of another
jurisdiction would be required thereby.

                 SECTION 11.10.   No Recourse Against Others.  No recourse for
the payment of the principal of or interest on any of the Securities or for any
claim based thereon or otherwise in respect thereof, and no recourse under or
upon any obligation, covenant or agreement of Bucyrus or any Guarantor in this
Indenture, or in any of the Securities or the Guarantees or because of the
creation of any Indebtedness represented hereby and thereby, shall be had
against any incorporator, stockholder, officer, director, employee or
controlling person of Bucyrus or any of its Subsidiaries.  Each Holder, by
accepting a Security, waives and releases all such liability.  The waiver and
release shall be part of the consideration for the issuance of the Securities.

                 SECTION 11.11.   Successors.  All agreements of Bucyrus in
this Indenture and the Securities shall bind Bucyrus' successors.  All
agreements of the Trustee in this Indenture shall bind its successors.

 SECTION 11.12.   Multiple Originals.  The parties may sign any number of copies
of this Indenture.  Each signed copy




<PAGE>   86

                                      -80-



shall be an original, but all of them together represent the same agreement.
One signed copy is enough to prove this Indenture.

                 SECTION 11.13.   Table of Contents; Headings.  The table of
contents, cross-reference sheet and headings of the Articles and Sections of
this Indenture have been inserted for convenience of reference only, are not
intended to be considered a part hereof and shall not modify or restrict any of
the terms or provisions hereof.

                 SECTION 11.14.   Severability Clause.  In case any provision
in this Indenture or in the Securities shall be invalid, illegal or
unenforceable, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

                          9-3/4% SENIOR NOTES DUE 2007

1.       Interest

                 BUCYRUS INTERNATIONAL, INC., a Delaware corporation (such
entity, and its successors and assigns under the Indenture, the "Company"),
promises to pay interest on the principal amount of this Security at the rate
per annum shown above.  The Company will pay interest semiannually on March 15
and September 15 of each year, commencing March 15, 1998.  Interest on the
Securities will accrue from the most recent date on which interest has been
paid or, if no interest has been paid, from September 24, 1997.  Interest will
be computed on the basis of a 360-day year of twelve 30-day months.  The
Company shall pay interest on overdue principal at 1% per annum in excess of
the rate borne by the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.       Method of Payment

                 The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the record date immediately preceding the interest
payment date even if Securities are canceled on registration of transfer or
registration of exchange (including pursuant to an Exchange Offer (as defined
in the Registration Agreement)) after the record date.  Holders must surrender
Securities to a Paying Agent to collect principal payments.  The Company will
pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts ("U.S. Legal
Tender").  However, the Company may pay principal and interest by its check
payable in such U.S. Legal Tender.  The Company may deliver any such interest
payment to the Paying Agent or to a Holder's registered address.

3.       Paying Agent and Registrar

                 Initially, Harris Trust and Savings Bank, a national banking
corporation (the "Trustee"), will act as Paying Agent and Registrar.  The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice.  The Company may act as Paying Agent, Registrar, co-Registrar
or transfer agent.

4.       Indenture

                 The Company issued the Securities under an Indenture dated as
of September 24, 1997 (the "Indenture"), among the Company, the Guarantors
party thereto and the Trustee.  This Security is one of a duly authorized issue
of Initial Securities of the Company designated as its 9-3/4% Senior Notes Due
2007 (the



                                      A-2

<PAGE>   91

"Initial Securities").  The Securities include the Initial Securities and the
Exchange Securities (as defined in the Indenture) issued in exchange for the
Initial Securities pursuant to the Registration Agreement.  The Initial
Securities and the Exchange Securities are treated as a single class of
securities under the Indenture.  The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S.C. Section  77aaa-77bbbb) as in effect
on the date of the Indenture (the "TIA").  Terms defined in the Indenture and
not defined herein have the meanings ascribed thereto in the Indenture.  The
Securities are subject to all such terms, and Securityholders are referred to
the Indenture and the TIA for a statement of those terms.  Any conflict between
this Security and the Indenture will be governed by the Indenture.

                 The Securities are unsecured senior obligations of the Company
limited to $150,000,000 aggregate principal amount (subject to Section 2.7 of
the Indenture).  The Indenture imposes certain limitations on the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries, the existence of
liens, the payment of dividends on, and redemption of, the Capital Stock of the
Company and its Restricted Subsidiaries, the sale or transfer of assets and
Subsidiary stock, the issuance or sale of Capital Stock of Restricted
Subsidiaries, the investments of the Company and its Restricted Subsidiaries,
consolidations, mergers and transfers of all or substantially all the assets of
the Company, and transactions with Affiliates.  In addition, the Indenture
limits the ability of the Company and its Restricted Subsidiaries to restrict
distributions and dividends from Restricted Subsidiaries.

                 To guarantee the due and punctual payment of the principal,
premium and interest, if any, on the Securities and all other amounts payable
by the Company under the Indenture and the Securities when and as the same
shall be due and payable, whether at maturity, by acceleration or otherwise,
according to the terms of the Securities and the Indenture, the Guarantors have
unconditionally guaranteed the obligations of the Company under the Indenture
and the Securities on an unsecured senior basis pursuant to the terms of the
Indenture.

                 In addition, at any time and from time to time on or prior to
September 15, 2000, the Company may redeem Securities with the net cash
proceeds of one or more Public Equity Offerings following which there is a
Public Market, at a redemption price equal to 109.75% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on an interest payment date that is on or prior to the
dated fixed for redemption); provided, however, that at least 66___% of the
original aggregate principal amount of the Securities must remain outstanding
after each such redemption (other that any Securities owned by the Company or
any of its Subsidiaries) and such redemption shall be effected within 60 days
of the consummation of the latest Public Equity Offering.

6.       Notice of Redemption

                 Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address.  Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000.  If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.  If a notice or communication is sent in the manner provided in
the Indenture, it is duly given, whether or not the addressee receives it.
Failure to send a notice or communication to a Holder or any defect in it shall
not affect its sufficiency with respect to other Holders.

7.       Change of Control

                 Upon a Change of Control, each Holder of Securities will have
the right to require the Company to purchase all or any part of the Securities
of such Holder at a purchase price in cash equal to 101% of the principal
amount of the Securities to be purchased plus accrued and unpaid interest, if
any, to the date of purchase (subject to the right of Holders of record on the
relevant record date to receive interest due on an interest payment date that
is on or prior to the date fixed for redemption) as provided in, and subject to
the terms of, the Indenture.

8.       Registration Agreement



                                      A-4

<PAGE>   93

                 The holder of this Security is entitled to the benefits of a
Registration Agreement, dated as of September 24, 1997, among the Company, the
Guarantors and the Initial Purchasers named therein (as such may be amended
from time to time, the "Registration Agreement").  Capitalized terms used in
this subsection but not defined herein have the meanings assigned to them in
the Registration Agreement.

                 If (i) within 60 days after the Issue Date, neither the
Exchange Offer Registration Statement nor the Shelf Registration Statement has
been filed with the Commission; (ii) within 150 days after the Issue Date, the
Exchange Offer Registration Statement has not been declared effective; (iii)
within 180 days after the Issue Date, neither the Exchange Offer has been
consummated nor the Shelf Registration Statement has been declared effective;
or (iv) after either the Exchange Offer Registration Statement or the Shelf
Registration Statement has been declared effective, such Registration Statement
thereafter ceases to be effective or usable (subject, in the case of the Shelf
Registration  Statement, to the exceptions set forth in Section 3(b)(i) or (ii)
of the Registration Agreement) in connection with resales of Initial Securities
or Exchange Securities in accordance with and during the periods specified in
Sections 2(e) and 3(b) of the Registration Agreement (each such event referred
to in clauses (i) through (iv), a "Registration Default"), liquidated damages
("Liquidated Damages") will accrue on the Initial Securities and the Exchange
Securities from and including the date on which any such Registration Default
shall occur to but excluding the date on which all Registration Defaults have
been cured.  Liquidated Damages will accrue at a rate of $0.05 per week per
$1,000 principal amount of the Securities during the 90-day period immediately
following the occurrence of any Registration Default and shall increase $0.05
per week per $1,000 principal amount of the Securities at the end of each
subsequent 90-day period, but in no event shall such Liquidated Damages exceed
$0.25 per week per $1,000 principal amount of Securities.

9.       Denominations; Transfer; Exchange

                 The Securities are in registered form, without coupons, and in
denominations of $1,000 and integral multiples of $1,000.  A Holder may
transfer or exchange Securities in accordance with the Indenture.  The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture, including any transfer tax or other similar
governmental charge payable in connection therewith.  The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a
selection of Securities to be redeemed or 15 days before an
interest payment date.





                                      A-5
<PAGE>   94



10.      Persons Deemed Owners

                 The registered Holder of this Security may be treated as the
owner of it for all purposes.

11.      Unclaimed Money

                 If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back
to the Company at its written request unless an abandoned property law
designates another Person.  After any such payment, Holders entitled to the
money must look only to the Company and not to the Trustee for payment.

12.      Discharge and Defeasance

                 Subject to certain conditions, the Company at any time may
terminate some or all of its obligations under the Securities and the Indenture
if the Company deposits with the Trustee money or U.S. Government Obligations
for the payment of principal and interest on the Securities to redemption or
maturity, as the case may be.

13.      Amendment, Waiver

                 Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the consent of the Holders
of at least a majority in principal amount outstanding of the Securities and
(ii) any past default or noncompliance with any provision may be waived with
the consent of the Holders of a majority in principal amount outstanding of the
Securities.  Subject to certain exceptions set forth in the Indenture, without
the consent of any Holder, the Company, the Guarantors and the Trustee may
amend the Indenture or the Securities to cure any ambiguity, defect or
inconsistency, to comply with Article 5 of the Indenture, to provide for
uncertificated Securities in addition to or in place of certificated
Securities, to add Guarantees with respect to the Securities, to release
Guarantors when permitted by the Indenture, to secure the Securities, to add
additional covenants or surrender rights and powers conferred on the Company,
to make any change that does not adversely affect the rights of any Holder or
to comply with any request of the SEC in connection with qualifying the
Indenture under the TIA.

14.      Defaults and Remedies

                 If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Securities then
outstanding may declare all the Securities to be due and payable.  Certain
events of bankruptcy or insolvency are Events of Default which will result in
the Securities being due



                                      A-6

<PAGE>   95

and payable immediately upon the occurrence of such Events of Default.

                 Holders may not enforce the Indenture or the Securities except
as provided in the Indenture.  The Trustee may refuse to enforce the Indenture
or the Securities unless it is offered reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of
the Securities may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing Default (except
a Default in payment of principal or interest) if and so long as a committee of
its trust officers determines that withholding notice is in the interest of the
Holders.

15.      Trustee Dealings with the Company

                 Subject to certain limitations imposed by the TIA, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or any of its Affiliates and may
otherwise deal with the Company or any of its Affiliates with the same rights
it would have if it were not Trustee.

16.      No Recourse Against Others

                 No recourse for the payment of the principal of, premium, if
any, or interest on any of the Securities or for any claim based thereon or
otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company or any Guarantor in the Indenture, or in
any of the Securities or Guarantees or because of the creation of any
Indebtedness represented hereby and thereby, shall be had against any
incorporator, stockholder, officer, director, employee, agent or controlling
person of the Company or any of its Subsidiaries.  Each Holder, by accepting a
Security, waives and releases all such liability.

17.      Guarantees

                 This Security will be entitled to the benefits of certain
Guarantees, if any, made for the benefit of the Holders.  Reference is hereby
made to the Indenture for a statement of the respective rights, limitations of
rights, duties and obligations thereunder of the Guarantors, the Trustee and
the Holders.

18.      Governing Law

                 The Indenture and the Securities shall be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflict of laws to the extent that the
application of the laws of another jurisdiction would be required thereby.

19.      Authentication

                 This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

20.      Abbreviations

                 Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with rights of
survivorship and not as tenants in common), CUST (= custodian), and U/G/M/A (=
Uniform Gift to Minors Act).

21.      CUSIP Numbers

                 Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Securities and has directed the Trustee to use CUSIP
numbers in notices of redemption as a convenience to Holders.  No
representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

                 The Company will furnish to any Holder upon written request
and without charge to the Holder a copy of the Indenture.  Requests may be made
as follows:

paid or, if no interest has been paid, from September 24, 1997.  Interest will
be computed on the basis of a 360-day year of twelve 30-day months.  The
Company shall pay interest on overdue principal at 1% per annum in excess of
the rate borne by the Securities, and it shall pay interest on overdue
installments of interest at the same rate to the extent lawful.

2.       Method of Payment

                 The Company will pay interest on the Securities (except
defaulted interest) to the Persons who are registered holders of Securities at
the close of business on the record date immediately preceding the interest
payment date even if Securities are canceled on registration of transfer or
registration of exchange (including pursuant to an Exchange Offer (as defined
in the Registration Agreement)) after the record date.  Holders must surrender
Securities to a Paying Agent to collect principal payments.  The Company will
pay principal and interest in money of the United States that at the time of
payment is legal tender for payment of public and private debts ("U.S. Legal
Tender").  However, the Company may pay principal and interest by its check
payable in such U.S. Legal Tender.  The Company may deliver any such interest
payment to the Paying Agent or to a Holder's registered address.

3.       Paying Agent and Registrar

                 Initially, Harris Trust and Savings Bank, a national banking
corporation (the "Trustee"), will act as Paying Agent and Registrar.  The
Company may appoint and change any Paying Agent, Registrar or co-registrar
without notice.  The Company may act as Paying Agent, Registrar, co-Registrar
or transfer agent.

4.       Indenture

                 The Company issued the Securities under an Indenture dated as
of September 24, 1997 (the "Indenture"), among the Company, the Guarantors
party thereto and the Trustee.  This Security is one of a duly authorized issue
of Exchange Securities of the Company designated as its 9-3/4% Senior Notes Due
2007 (the





                                      B-2
<PAGE>   104

"Exchange Securities").  The Securities include the Initial Securities (as
defined in the Indenture) and the Exchange Securities issued in exchange for
the Initial Securities pursuant to the Registration Agreement.  The Initial
Securities and the Exchange Securities are treated as a single class of
securities under the Indenture.  The terms of the Securities include those
stated in the Indenture and those made part of the Indenture by reference to
the Trust Indenture Act of 1939 (15 U.S.C. Section  77aaa-77bbbb) as in effect
on the date of the Indenture (the "TIA").  Terms defined in the Indenture and
not defined herein have the meanings ascribed thereto in the Indenture.  The
Securities are subject to all such terms, and Securityholders are referred to
the Indenture and the TIA for a statement of those terms.  Any conflict between
this Security and the Indenture will be governed by the Indenture.

                 The Securities are unsecured senior obligations of the Company
limited to $150,000,000 aggregate principal amount (subject to Section 2.7 of
the Indenture).  The Indenture imposes certain limitations on the Incurrence of
Indebtedness by the Company and its Restricted Subsidiaries, the existence of
liens, the payment of dividends on, and redemption of, the Capital Stock of the
Company and its Restricted Subsidiaries, the sale or transfer of assets and
Subsidiary stock, the issuance or sale of Capital Stock of Restricted
Subsidiaries, the investments of the Company and its Restricted Subsidiaries,
consolidations, mergers and transfers of all or substantially all the assets of
the Company, and transactions with Affiliates.  In addition, the Indenture
limits the ability of the Company and its Restricted Subsidiaries to restrict
distributions and dividends from Restricted Subsidiaries.

                 To guarantee the due and punctual payment of the principal,
premium and interest, if any, on the Securities and all other amounts payable
by the Company under the Indenture and the Securities when and as the same
shall be due and payable, whether at maturity, by acceleration or otherwise,
according to the terms of the Securities and the Indenture, the Guarantors have
unconditionally guaranteed the obligations of the Company under the Indenture
and the Securities on an unsecured senior basis pursuant to the terms of the
Indenture.

5.       Optional Redemption

                 Except as set forth in the next paragraph, the Securities may
not be redeemed at the option of the Company prior to, September 15, 2002.
Thereafter, the Securities will be redeemable, at the Company's option, in
whole or in part, at any time or from time to time, at the following redemption
prices (expressed in percentages of principal amount), plus accrued and unpaid
interest, if any, to the redemption date (subject to the right of Holders of
record on the relevant record date to receive interest due on an interest
payment date that is on or prior to

      2005 and thereafter                                                            100.000%
</TABLE>
                 In addition, at any time and from time to time on or prior to
September 15, 2000, the Company may redeem Securities with the net cash
proceeds of one or more Public Equity Offerings following which there is a
Public Market, at a redemption price equal to 109.75% of the principal amount
thereof, plus accrued and unpaid interest, if any, to the redemption date
(subject to the right of Holders of record on the relevant record date to
receive interest due on an interest payment date that is on or prior to the
dated fixed for redemption); provided, however, that at least 6___% of the
original aggregate principal amount of the Securities must remain outstanding
after each such redemption (other that any Securities owned by the Company or
any of its Subsidiaries) and such redemption shall be effected within 60 days
of the consummation of the latest Public Equity Offering.

6.       Notice of Redemption

                 Notice of redemption will be mailed by first-class mail at
least 30 days but not more than 60 days before the redemption date to each
Holder of Securities to be redeemed at his registered address.  Securities in
denominations larger than $1,000 may be redeemed in part but only in whole
multiples of $1,000.  If money sufficient to pay the redemption price of and
accrued interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with the Paying Agent on or before the redemption
date and certain other conditions are satisfied, on and after such date
interest ceases to accrue on such Securities (or such portions thereof) called
for redemption.  If a notice or communication is sent in the manner provided in
the Indenture, it is duly given, whether or not the addressee receives it.
Failure to send a notice or communication to a Holder or any defect in it shall
not affect its sufficiency with respect to other Holders.

7.       Change of Control

                 Upon a Change of Control, each Holder of Securities will have
the right to require the Company to purchase all or any part of the Securities
of such Holder at a purchase price in cash equal to 101% of the principal
amount of the Securities to be purchased plus accrued and unpaid interest, if
any, to the date of purchase (subject to the right of Holders of record on the
relevant record date to receive interest due on an interest payment date that
is on or prior to the date fixed for redemption) as provided in, and subject to
the terms of, the Indenture.

<PAGE>   106

                 The Securities are in registered form, without coupons, and in
denominations of $1,000 and integral multiples of $1,000.  A Holder may
transfer or exchange Securities in accordance with the Indenture.  The
Registrar may require a Holder, among other things, to furnish appropriate
endorsements or transfer documents and to pay any taxes and fees required by
law or permitted by the Indenture, including any transfer tax or other similar
governmental charge payable in connection therewith.  The Registrar need not
register the transfer of or exchange any Securities selected for redemption
(except, in the case of a Security to be redeemed in part, the portion of the
Security not to be redeemed) or any Securities for a period of 15 days before a
selection of Securities to be redeemed or 15 days before an interest payment
date.

9.       Persons Deemed Owners

                 The registered Holder of this Security may be treated as the
owner of it for all purposes.

10.      Unclaimed Money

                 If money for the payment of principal or interest remains
unclaimed for two years, the Trustee or Paying Agent shall pay the money back
to the Company at its written request unless an abandoned property law
designates another Person.  After any such payment, Holders entitled to the
money must look only to the Company and not to the Trustee for payment.

11.      Discharge and Defeasance

                 Subject to certain conditions, the Company at any time may
terminate some or all of its obligations under the Securities and the Indenture
if the Company deposits with the Trustee money or U.S. Government Obligations
for the payment of principal and interest on the Securities to redemption or
maturity, as the case may be.

12.      Amendment, Waiver

                 Subject to certain exceptions set forth in the Indenture, (i)
the Indenture or the Securities may be amended with the consent of the Holders
of at least a majority in principal amount outstanding of the Securities and
(ii) any past default or noncompliance with any provision may be waived with
the consent of the Holders of a majority in principal amount outstanding of the
Securities.  Subject to certain exceptions set forth in the Indenture, without
the consent of any Holder, the Company, the Guarantors and the Trustee may
amend the Indenture or the Securities to cure any ambiguity, defect or
inconsistency, to comply with Article 5 of the Indenture, to provide for
uncertificated Securities in addition to or in place of certificated
Securities, to add Guarantees with respect to the



                                      B-5

<PAGE>   107

Securities, to release Guarantors when permitted by the Indenture, to secure
the Securities, to add additional covenants or surrender rights and powers
conferred on the Company, to make any change that does not adversely affect the
rights of any Holder or to comply with any request of the SEC in connection
with qualifying the Indenture under the TIA.

13.      Defaults and Remedies

                 If an Event of Default occurs and is continuing, the Trustee
or the Holders of at least 25% in principal amount of the Securities then
outstanding may declare all the Securities to be due and payable.  Certain
events of bankruptcy or insolvency are Events of Default which will result in
the Securities being due and payable immediately upon the occurrence of such
Events of Default.

                 Holders may not enforce the Indenture or the Securities except
as provided in the Indenture.  The Trustee may refuse to enforce the Indenture
or the Securities unless it is offered reasonable indemnity or security.
Subject to certain limitations, Holders of a majority in principal amount of
the Securities may direct the Trustee in its exercise of any trust or power.
The Trustee may withhold from Holders notice of any continuing Default (except
a Default in payment of principal or interest) if and so long as a committee of
its trust officers determines that withholding notice is in the interest of the
Holders.

14.      Trustee Dealings with the Company

                 Subject to certain limitations imposed by the TIA, the Trustee
under the Indenture, in its individual or any other capacity, may become the
owner or pledgee of Securities and may otherwise deal with and collect
obligations owed to it by the Company or any of its Affiliates and may
otherwise deal with the Company or any of its Affiliates with the same rights
it would have if it were not Trustee.

15.      No Recourse Against Others

                 No recourse for the payment of the principal of, premium, if
any, or interest on any of the Securities or for any claim based thereon or
otherwise in respect thereof, and no recourse under or upon any obligation,
covenant or agreement of the Company or any Guarantor in the Indenture, or in
any of the Securities or Guarantees or because of the creation of any
Indebtedness represented hereby and thereby, shall be had against any
incorporator, stockholder, officer, director, employee, agent or controlling
person of the Company or any of its Subsidiaries.  Each Holder, by accepting a
Security, waives and releases all such liability.

16.      Guarantees





                                      B-6
<PAGE>   108

                 This Security will be entitled to the benefits of certain
Guarantees, if any, made for the benefit of the Holders.  Reference is hereby
made to the Indenture for a statement of the respective rights, limitations of
rights, duties and obligations thereunder of the Guarantors, the Trustee and
the Holders.

17.      Governing Law

                 The Indenture and the Securities shall be governed by, and
construed in accordance with, the laws of the State of New York without giving
effect to applicable principles of conflict of laws to the extent that the
application of the laws of another jurisdiction would be required thereby.

18.      Authentication

                 This Security shall not be valid until an authorized signatory
of the Trustee (or an authenticating agent) manually signs the certificate of
authentication on the other side of this Security.

19.      Abbreviations

                 Customary abbreviations may be used in the name of a
Securityholder or an assignee, such as TEN COM (= tenants in common), TEN ENT
(= tenants by the entireties), JT TEN (= joint tenants with rights of
survivorship and not as tenants in common), CUST (= custodian), and U/G/M/A (=
Uniform Gift to Minors Act).

20.      CUSIP Numbers

                 Pursuant to a recommendation promulgated by the Committee on
Uniform Security Identification Procedures the Company has caused CUSIP numbers
to be printed on the Securities and has directed the Trustee to use CUSIP
numbers in notices of redemption as a convenience to Holders.  No
representation is made as to the accuracy of such numbers either as printed on
the Securities or as contained in any notice of redemption and reliance may be
placed only on the other identification numbers placed thereon.

                 The Company will furnish to any Holder upon written request
and without charge to the Holder a copy of the Indenture.  Requests may be made
as follows:

Harris Trust and Savings Bank
111 West Monroe Street
12th Floor
Chicago, Illinois 60603

Ladies and Gentlemen:

                 In connection with our proposed purchase of 9-3/4% Senior
Notes Due 2007 (the "Securities") of Bucyrus International, Inc., a Delaware
corporation (the "Company"), we confirm that:

                 1.       We have received a copy of the Offering Memorandum
         (the "Offering Memorandum"), dated September 17, 1997, relating to the
         Securities and such other information as we deem necessary in order to
         make our investment decision.  We acknowledge that we have read and
         agreed to the matters stated in the section entitled "Notice to
         Investors" of such Offering Memorandum.

                 2.       We understand that any subsequent transfer of the
         Securities is subject to certain restrictions and conditions set forth
         in the Indenture relating to the Securities (the "Indenture") as
         described in the Offering Memorandum and the undersigned agrees to be
         bound by, and not to resell, pledge or otherwise transfer the
         Securities except in compliance with, such restrictions and conditions
         and the Securities Act of 1933, as amended (the "Securities Act"), and
         all applicable State securities laws.

                 3.       We understand that the offer and sale of the
         Securities have not been registered under the Securities Act, and that
         the Securities may not be offered or sold within the United States or
         to, or for the account or benefit of, U.S. persons except as permitted
         in the following sentence.  We agree, on our own behalf and on behalf
         of any accounts for which we are acting as hereinafter stated, that if
         we should sell any Securities, we will do so only (i) to the Company
         or any subsidiary thereof, (ii) inside the United States in accordance
         with Rule 144A under the Securities Act to a "qualified institutional
         buyer" (as defined in Rule 144A promulgated under the Securities Act),
         (iii) inside the United States to an institutional "accredited
         investor" (as defined below) that, prior to such transfer, furnishes
         (or has furnished on its behalf by a U.S. broker-dealer) to the





                                      C-1

         Trustee (as defined in the Indenture) a signed letter containing
         certain representations and agreements relating to the restrictions on
         transfer of the Securities (the form of which letter can be obtained
         from the Trustee), (iv) outside the United States in accordance with
         Rule 904 of Regulation S promulgated under the Securities Act to
         non-U.S. persons, (v) pursuant to the exemption from registration
         provided by Rule 144 under the Securities Act (if available), or (vi)
         pursuant to an effective registration statement under the Securities
         Act, and we further agree to provide to any person purchasing any of
         the Securities from us a notice advising such purchaser that resales
         of the Securities are restricted as stated herein.

                 4.       We understand that, on any proposed resale of any
         Securities, we will be required to furnish to the Trustee and the
         Company such certification, legal opinions and other information as
         the Trustee and the Company may reasonably require to confirm that the
         proposed sale complies with the foregoing restrictions.  We further
         understand that the Securities purchased by us will bear a legend to
         the foregoing effect.

                 5.       We are an institutional "accredited investor" (as
         defined in Rule 501(a)(1), (2), (3) or (7) of Regulation D under the
         Securities Act) and have such knowledge and experience in financial
         and business matters as to be capable of evaluating the merits and
         risks of our investment in the Securities, and we and any accounts for
         which we are acting are each able to bear the economic risk of our or
         their investment, as the case may be.

                 6.       We are acquiring the Securities purchased by us for
         our account or for one or more accounts (each of which is an
         institutional "accredited investor") as to each of which we exercise
         sole investment discretion.

Ladies and Gentlemen:

                 In connection with our proposed sale of $[          ]

been effected pursuant to and in accordance with Regulation S under the U.S.

         in the United States;

                 (2)      either (a) at the time the buy offer was originated,
         the transferee was outside the United States or we and any person
         acting on our behalf reasonably believed that the transferee was
         outside the United States, or (b) the transaction was executed in, on
         or through the facilities of a designated off-shore securities market
         and neither we nor any person acting on our behalf knows that the
         transaction has been pre-arranged with a buyer in the United States;

                 (3)      no directed selling efforts have been made in the
         United States in contravention of the requirements of Rule 903(b) or
         Rule 904(b) of Regulation S, as applicable;

                 (4)      the transaction is not part of a plan or scheme to
         evade the registration requirements of the Securities Act; and

                 (5)      we have advised the transferee of the transfer
         restrictions applicable to the Securities.

                         MANAGEMENT SERVICES AGREEMENT


           THIS MANAGEMENT SERVICES AGREEMENT (this "Agreement") is dated
      on or after the consummation of the tender offer by and among Bucyrus
      International, Inc., a Delaware corporation (the "Corporation"),
      Boonville Mining Services, Inc., a Delaware corporation, Minserco,
      Inc., a Delaware corporation and Von's Welding, Inc., a Wyoming
      corporation (collectively the "Subsidiaries"); and American
      Industrial Partners, a Delaware general partnership ("AIP").

                                   Background

           Subject to terms and conditions of this Agreement, the
      Corporation desires to retain AIP to provide certain management
      services to the Corporation.

                              Terms and Conditions

           In consideration of the mutual covenants contained herein and
      intending to be legally bound hereby, the parties agree as follows:

           1. Management Services: During the term of this Agreement, AIP
      shall provide general management, financial and other corporate
      advisory services to the Corporation.  Such management services shall
      be performed by the qualified officers, employees or agents or AIP,
      and AIP shall at all times direct, monitor and supervise the
      performance of such services by such officers, employees or agents.

           2. Fees and Expenses:

           (a) The Corporation shall pay to AIP an annual management fee
      (the "Management Fee") of One Million Four Hundred Fifty Thousand
      Dollars ($1,450,000).  The Management Fee shall be payable
      semi-annually forty-five (45) days after the scheduled interest
      payment date for the Company's 9 3/4% Senior Notes Due 2007,
      beginning on or after the consummation of the Tender Offer or at such
      other times as the Corporation and AIP shall otherwise agree;
      provided that if any date on which payment of the Management Fee is
      required hereunder is not a business day, the Corporation shall pay
      such Management Fee on the first business day following the date on which 
      payment was otherwise due.
        
           (b) In addition to the Management Fees payable pursuant to this
      Section 2, the Corporation agrees to promptly reimburse AIP for all
      out-of-pocket expenses 

<PAGE>   2

      incurred by AIP in providing the services contemplated by this Agreement,
      including fees and expenses paid to consultants, subcontractors and other
      third parties in connection with such services.
        
           (c) The Corporation and the Subsidiaries (collectively, the
      "Guarantors"), jointly and severally, hereby guarantee the
      Corporation's payment of all amounts owing to AIP (i) subject to
      paragraph 2(d) below, under paragraph 2(a) of this Agreement and (ii)
      under paragraph 2(b) of this Agreement.

           (d) Notwithstanding anything to the contrary contained herein:
      (i) the Corporation shall not be required to pay the Management Fee
      if and for so long as (A) any such payment would violate, breach or
      otherwise constitute a default (or any event which might with the
      lapse of time or giving of notice or both, constitute a default)
      under any of the Corporation's financing agreements, and (ii) none of
      the Guarantors shall be required to make any payments pursuant to
      Section 2(c)(i) of this Agreement if any such payment would violate,
      breach or otherwise constitute a default (or any event which might
      constitute a default) under any of the Guarantors' financing
      agreements, including, without limitation, the Credit Agreement,
      dated as of September 24, 1997, among the Corporation, Bank One,
      Wisconsin, and the Lenders from time to time party thereto.

           (e) Interest will accrue on all due and unpaid Management Fees
      at the lower of (i) the rate per annum equal to ten percent (10%) or
      (ii) the maximum rate permitted by law until such time as such
      Management Fees are paid, and such interest shall compound annually.

           (f) Notwithstanding the provisions of Section 2(a) hereof, the
      lability of the Corporation for any semi-annual Management Fee
      payment hereunder shall not accrue, and AIP shall have no right for
      payment in respect thereto, unless AIP continues to perform the
      management services described in Section 1 through the end of the
      applicable semi-annual period, and no payment obligation shall arise
      on the part of the Corporation for the performance of services by AIP
      for any partial semi-annual period (except for any partial
      semi-annual period ending on the termination of this Agreement,
      whereupon the Management Fee shall be pro rated, and shall be
      payable, for such period).

           3. Binding Effect; Assignability.  This Agreement shall be
      binding upon and inure to the benefit of the parties hereto and their 
      successors and permitted

                                      2

<PAGE>   3

      assigns.  This Agreement may not be transferred or assigned by any
      party without the written consent of each other party.

           4. Entire Agreement; Amendment.  This Agreement constitutes the
      entire agreement and understanding between the parties with respect
      to the subject matter hereof.  This Agreement may be amended or
      modified, or any provision hereof may be waived, provided that such
      amendment or waiver is set forth in a writing executed by the
      parties.  No courses of dealing between or among any persons having
      any interest in this Agreement will be deemed effective to modify,
      amend or discharge any part of this Agreement or any rights or
      obligations or any person under or by reason of this Agreement.

           5. Term.  Except as provided for herein, this Agreement shall
      commence on the date hereof and shall terminate on the earlier of (i)
      the tenth anniversary of the date hereof and (ii) such other date as
      to which AIP and the Corporation mutually agree.  The provisions of
      Section 6 shall survive the termination of this Agreement.

           6. Indemnification.  The Corporation and the Guarantors hereby
      jointly and severally agree to indemnify and hold harmless AIP and
      its partners, employees, agents, representatives and affiliates (each
      being an "Indemnified Party") from and against any and all losses,
      claims, damages and liabilities to which such Indemnified Party may
      become subject under any applicable federal or state law, any claim
      made by any third party or otherwise, relating to or arising out of
      the engagement of AIP pursuant to, and the performance by AIP of the
      services contemplated by, this Agreement, and the Corporation and the
      Guarantors jointly and severally will reimburse any indemnified Party
      for all costs and expenses (including attorneys' fees and expenses)
      as they are incurred in connection with the investigation of,
      preparation for or defense of any pending or threatening claim, or
      any action or proceeding arising therefrom, whether or not such
      Indemnified Party is a party hereto.  None of the Corporation and the
      Guarantors will be liable under this Section 6, and an Indemnified
      Party shall reimburse the Corporation or the Guarantors for any
      related payments made by it under this Section 6, to the extent that
      any loss, claim, damage, liability, cost or expense is determined by
      a court, in a final judgment from which not further appeal may be
      taken, to have resulted primarily from the gross negligence or
      willful misconduct of such Indemnified Party.  No Indemnified Party shall
      be liable to the Corporation or any of the

                                      3
        
<PAGE>   4

      Guarantors for honest mistakes of judgment, or for action or
      inaction, taken in good faith in the performance of management
      services under this Agreement to the extent such action would satisfy
      the standards for indemnification set forth in Section 6.

           7. Permissible Activities.  Subject to all applicable provisions
      of Delaware law that impose fiduciary duties upon AIP or its partners
      or affiliates, nothing herein shall in any way preclude AIP, it
      partners or affiliates from engaging in any business activities or
      from performing services for its or their own account or for the
      account of others.

           8. Governing Law.  The validity, performance, construction and
      effect of this Agreement shall be governed by and construed in
      accordance with the internal law of the State of New York.

         (c)    In connection with the Registered Exchange Offer, the Issuers

    Exchange Offer Registration Statement, together with an appropriate letter
    of transmittal and related documents;

        (ii)    keep the Registered Exchange Offer open for not less than 30

        (iv)    comply in all respects with all applicable laws.

        (d)     As soon as practicable after the close of the Registered

    New Securities equal in principal amount to the Securities of such Holder
    so accepted for exchange.

        (e)     The Initial Purchasers and the Issuers acknowledge that,
pursuant to interpretations by the Commission's staff of Section 5 of the Act,
and in the absence of an applicable exemption therefrom, each Exchanging Dealer
is required to deliver a Prospectus in connection with a sale of any New
Securities received by such Exchanging Dealer pursuant to the Registered
Exchange Offer in exchange for Securities acquired for its own account as a
result of market-making activities or other trading activities.  Accordingly,
the Issuers shall:

        (i)     include the information set forth in Annex A hereto on the cover
    of the Exchange Offer Registration Statement, in Annex B hereto in the
    forepart of the Exchange Offer Registration Statement in a section setting

<PAGE>   6

                                      -6-


    details of the Exchange Offer, and in Annex C hereto in the underwriting or
    plan of distribution section of the Prospectus forming a part of the        
    Exchange Offer Registration Statement, and include the information set
    forth in Annex D hereto in the Letter of Transmittal delivered pursuant to
    the Registered Exchange Offer; and

        (ii)    use their best efforts to keep the Exchange Offer Registration
    Statement continuously effective under the Act during the Exchange Offer
    Registration Period for delivery by Exchanging Dealers in connection with
    sales of New Securities received pursuant to the Registered Exchange Offer,
    as contemplated by Section 4(h) below.

        (f)      In the event that any Initial Purchaser determines that it is
not eligible to participate in the Registered Exchange Offer with respect to
the exchange of Securities constituting any portion of an unsold allotment, at
the request of such Initial Purchaser, the Issuers shall issue and deliver to
such Initial Purchaser or the party purchasing New Securities registered under
a Shelf Registration Statement as contemplated by Section 3 hereof from such
Initial Purchaser, in exchange for such Securities, a like principal amount of
New Securities.  The Issuers shall seek to cause the CUSIP Service Bureau to
issue the same CUSIP number for such New Securities as for New Securities
issued pursuant to the Registered Exchange Offer.

        3.       Shelf Registration.  If (i) because of any change in law or
applicable interpretations thereof by the Commission's staff, the Issuers
determine upon advice of their outside counsel that they are not permitted to
effect the Registered Exchange Offer as contemplated by Section 2 hereof, or
(ii) for any reason the Exchange Offer Registration Statement is not declared
effective within 150 days of the Closing Date, or (iii)  any Holder is not
eligible to participate in the Registered Exchange Offer (other than by reason
of such Holder's failure to comply with Section 4(o), or (iv) in the case of
any Initial Purchaser that participates in the Registered Exchange Offer or
acquires New Securities pursuant to Section 2(f) hereof, such Initial Purchaser
does not receive freely tradeable New Securities in exchange for Securities
constituting any portion of an unsold allotment (it being understood that, for
purposes of this Section 3, (x) the requirement that an Initial Purchaser
deliver a Prospectus containing the information required by Items 507 and/or
508 of Regulation S-K under the Act in connection with sales of New Securities
acquired in exchange for such Securities shall result in such New Securities
being not "freely tradeable" but (y) the requirement that an Exchanging Dealer
deliver a Prospectus in connection with sales of New Securities acquired in





<PAGE>   7

                                      -7-


the Registered Exchange Offer in exchange for Securities acquired as a result
of market-making activities or other trading activities shall not result in
such New Securities being not "freely tradeable"), the following provisions
shall apply:

        (a)     The Issuers shall as promptly as practicable (but in no event
    more than 45 days after so required or requested pursuant to this Section
    3), file with the Commission and thereafter shall use their best efforts to
    cause to be declared effective under the Act a Shelf Registration Statement
    by the 180th day after the Issue Date (but not earlier than the 180th day
    after a request by an Initial Purchaser) relating to the offer and sale of
    the Securities or the New Securities, as applicable, by the Holders from
    time to time in accordance with the methods of distribution elected by such
    Holders and set forth in such Shelf Registration Statement; provided,
    however, that, with respect to New Securities received by an Initial
    Purchaser in exchange for securities constituting any portion of an unsold
    allotment, the Issuers may, if permitted by current interpretations by the
    Commission's staff, file a post-effective amendment to the Exchange Offer
    Registration Statement containing the information required by Regulation
    S-K Items 507 and/or 508, as applicable, in satisfaction of their
    obligations under this paragraph (a) with respect thereto, and any such
    Exchange Offer Registration Statement, as so amended, shall be referred to
    herein as, and governed by the provisions herein applicable to, a Shelf
    Registration Statement.

        (b)     The Issuers shall use their best efforts to keep the Shelf
    Registration Statement continuously effective in order to permit the
    Prospectus forming part thereof to be usable by Holders for a period of two
    years from the date the Shelf Registration Statement is declared effective
    by the Commission or such shorter period that will terminate when all the
    Securities or New Securities, as applicable, covered by the Shelf
    Registration Statement have been sold pursuant to the Shelf Registration
    Statement (in any such case, such period being called the "Shelf
    Registration Period").  The Issuers shall be deemed not to have used their
    best efforts to keep the Shelf Registration Statement effective during the
    requisite period if any Issuer voluntarily takes any action that would
    result in Holders of securities covered thereby not being able to offer and
    sell such securities during that period, unless (i) such action is required
    by applicable law, or (ii) such action is taken by such Issuer in good
    faith and for valid business reasons (not including avoidance of such
    Issuer's obligations

                                      -8-


    hereunder), including the acquisition or divestiture of assets, so  long as
    such Issuer promptly thereafter complies with the requirements of Section
    4(k) hereof, if applicable.

        4.       Registration Procedures.  In connection with any Shelf
Registration Statement and, to the extent applicable, any Exchange Offer
Registration Statement, the following provisions shall apply:

        (a)      The Issuers shall furnish to you, prior to the filing thereof
    with the Commission, a copy of any Shelf Registration Statement and any
    Exchange Offer Registration Statement, and each amendment thereof and each
    amendment or supplement, if any, to the Prospectus included therein and
    shall use their best efforts to reflect in each such document, when so
    filed with the Commission, such comments as you reasonably may propose.

        (b)      The Issuers shall ensure that (i) any Registration Statement
    and any amendment thereto and any Prospectus forming part thereof and any
    amendment or supplement thereto complies in all material respects with the
    Act and the rules and regulations thereunder, (ii) any Registration
    Statement and any amendment thereto does not, when it becomes effective,
    contain an untrue statement of a material fact or omit to state a material
    fact required to be stated therein or necessary to make the statements
    therein not misleading and (iii) any Prospectus forming part of any
    Registration Statement, and any amendment or supplement to such Prospectus,
    does not include an untrue statement of a material fact or omit to state a
    material fact necessary in order to make the statements, in the light of
    the circumstances under which they were made, not misleading.

        (c)      (1)     The Issuers shall advise you or your representative
    and, in the case of a Shelf Registration Statement, the Holders of
    securities covered thereby, and, if requested by you or your representative
    or any such Holder, confirm such advice in writing:

                 (i)    when a Registration Statement and any amendment thereto
         has been filed with the Commission and when the Registration Statement
         or any post-effective amendment thereto has become effective; and

                (ii)    of any request by the Commission for amendments or
         supplements to the Registration Statement or the Prospectus included
         therein or for additional information.

                                      -9-


        (2)   The Issuers shall advise you or your representative and, in the
    case of a Shelf Registration Statement, the Holders of securities covered
    thereby, and, in the case of an Exchange Offer Registration Statement, any
    Exchanging Dealer which has provided in writing to the Company a telephone
    or facsimile number and address for notices, and, if requested by you or
    your representative or any such Holder or Exchanging Dealer, confirm such
    advice in writing:

                (i)   of the issuance by the Commission of any stop order
         suspending the effectiveness of the Registration Statement or the
         initiation of any proceedings for that purpose;

                (ii)   of the receipt by the Issuers of any notification with
         respect to the suspension of the qualification of the securities
         included therein for sale in any jurisdiction or the initiation or
         threatening of any proceeding for such purpose; and

                (iii)   of the happening of any event that requires the making
         of any changes in the Registration Statement or the Prospectus so
         that, as of such date, the statements therein are not misleading and
         do not omit to state a material fact required to be stated therein or
         necessary to make the statements therein (in the case of the
         Prospectus, in light of the circumstances under which they were made)
         not misleading (which advice shall be accompanied by an instruction to
         suspend the use of the Prospectus until the requisite changes have
         been made).

         (d)      The Issuers shall use their best efforts to obtain the
    withdrawal of any order suspending the effectiveness of any Registration
    Statement at the earliest possible time.

         (e)      The Issuers shall furnish to each Holder of Securities covered
    by any Shelf Registration Statement, without charge, at least one copy of

    reference).

         (f)      The Issuers shall, during the Shelf Registration Period,
    deliver to each Holder of Securities any Shelf Registration Statement,
    without charge, as many copies of the Prospectus (including each
    preliminary Prospectus)





<PAGE>   10

                                      -10-


    included in such Shelf Registration Statement and any amendment or
    supplement thereto as such Holder may reasonably request; and the   Issuers
    consent to the use of the Prospectus or any amendment or supplement thereto
    by each of the selling Holders of securities in connection with the
    offering and sale of the securities covered by the Prospectus or any
    amendment or supplement thereto.

         (g)      The Issuers shall furnish to each Exchanging Dealer which so
    requests, without charge, at least one copy of the Exchange Offer
    Registration Statement and any post-effective amendment thereto, including
    financial statements and schedules, any documents incorporated by reference
    therein, and, if the Exchanging Dealer so requests in writing, all exhibits
    (including those incorporated by reference).

         (h)      The Issuers shall, during the Exchange Offer Registration
    Period, promptly deliver to each Exchanging Dealer, without charge, as many
    copies of the Prospectus included in such Exchange Offer Registration
    Statement and any amendment or supplement thereto as such Exchanging Dealer
    may reasonably request for delivery by such Exchanging Dealer in connection
    with a sale of New Securities received by it pursuant to the Registered
    Exchange Offer; and the Issuers consent to the use of the Prospectus or any
    amendment or supplement thereto by any such Exchanging Dealer, as
    aforesaid.

        (i)      Prior to the Registered Exchange Offer or any other offering
    of securities pursuant to any Registration Statement, the Issuers shall
    register or qualify or cooperate with the Holders of securities included
    therein and their respective counsel in connection with the registration or
    qualification of such securities for offer and sale under the securities or
    blue sky laws of such jurisdictions as any such Holders reasonably request
    in writing and do any and all other acts or things necessary or advisable
    to enable the offer and sale in such jurisdictions of the securities
    covered by such Registration Statement; provided, however, that the Issuers
    will not be required to qualify generally to do business in any
    jurisdiction where it is not then so qualified or to take any action which
    would subject it to general service of process or to taxation in any such
    jurisdiction where it is not then so subject.

        (j)      The Issuers shall cooperate with the Holders of Securities to
    facilitate the timely preparation and delivery





<PAGE>   11

                                      -11-

    Registration Statement free of any restrictive legends and in such
    denominations and registered in such names as Holders may request prior to
    sales of securities pursuant to such Registration Statement.

        (k)      Upon the occurrence of any event contemplated by paragraph
    (c)(2)(iii) above, the Issuers shall promptly prepare a post-effective
    amendment to any Registration Statement or an amendment or supplement to
    the related Prospectus or file any other required document so that, as
    thereafter delivered to purchasers of the Securities included therein, the
    Prospectus will not include an untrue statement of a material fact or omit
    to state any material fact necessary to make the statements therein, in the
    light of the circumstances under which they were made, not misleading.

        (l)      Not later than the effective date of any such Registration
    Statement hereunder, the Issuers shall provide a CUSIP number for the

        (m)      The Issuers shall use their best efforts to comply with all
    applicable rules and regulations of the Commission and shall make generally

    Act in a timely manner.

        (o)      The Issuers may require each Holder of Securities to be sold
    pursuant to any Shelf Registration Statement to furnish to the Issuers such
    information regarding the Holder and the distribution of such Securities as
    the Issuers may from time to time reasonably require for inclusion in such
    Registration Statement.  No Holder may include any of its Securities in any
    Shelf Registration Statement pursuant to this Agreement unless and until
    such Holder furnishes to the issuers in writing, within 20 days after
    receipt of a written request therefor, such information as the Issuers may
    reasonably request, including, but not limited to, information specified by
    Regulation S-K or otherwise

    required by the Commission for use in connection with any Shelf
    Registration Statement or Prospectus or preliminary Prospectus included
    therein.  Each Holder as to which any Shelf Registration Statement is being
    effected agrees to furnish promptly to the Issuers all information required
    to be disclosed in order to make the information previously furnished to
    the Issuers by such Holder not materially misleading.

        (p)      The Issuers shall, if requested, promptly incorporate in a
    Prospectus supplement or post-effective amendment to a Shelf Registration
    Statement, such information as the Managing Underwriters and Majority
    Holders reasonably agree should be included therein and shall make all
    required filings of such Prospectus supplement or post-effective amendment
    as soon as notified of the matters to be incorporated in such Prospectus
    supplement or post-effective amendment.

        (q)      In the case of any Shelf Registration Statement, the Issuers
    shall enter into such agreements (including underwriting agreements) and
    take all other appropriate actions in order to expedite or facilitate the
    registration or the disposition of the Securities, and in connection
    therewith, if an underwriting agreement is entered into, cause the same to
    contain indemnification provisions and procedures no less favorable than
    those set forth in Section 6 (or such other provisions and procedures
    acceptable to the Majority Holders and the Managing Underwriters, if any)
    with respect to all parties to be indemnified pursuant to Section 6 from
    Holders of Securities to the Company.

        (r)      In the case of any Shelf Registration Statement, the Issuers
    shall (i) make reasonably available for inspection by the Holders of
    Securities to be registered thereunder, any underwriter participating in

    officers, directors and employees to supply all relevant information
    reasonably requested by the Holders or any such underwriter, attorney,
    accountant or agent in connection with any such Registration Statement as

    that any information that is designated in writing by the Issuers, in good
    faith, as confidential at the time of delivery of such

    underwriter, attorney, accountant or agent, unless such disclosure is made
    in connection with a court proceeding or required by law, or such
    information becomes available to the public generally or through a third
    party without an accompanying obligation of confidentiality; (iii) make
    such representations and warranties to the Holders of Securities registered
    thereunder and the underwriters, if any, in form, substance and scope as
    are customarily made by issuers to underwriters in primary underwritten
    offerings and covering matters including, but not limited to, those set
    forth in the Purchase Agreement; (iv) obtain opinions of counsel to the
    Issuers and updates thereof (which counsel and opinions (in form, scope and
    substance) shall be reasonably satisfactory to the Managing Underwriters,
    if any) addressed to each selling Holder of Securities registered
    thereunder and the underwriters, if any, in customary form and covering
    such matters as are customarily covered in opinions requested in
    underwritten offerings; (v) obtain "cold comfort" letters and updates
    thereof from the independent certified public accountants of the Issuers

    any subsidiary of the Issuers or of any business acquired by the Issuers
    for which financial statements and financial data are, or are required to
    be, included in the Registration Statement), addressed to each selling
    Holder of securities registered thereunder and the underwriters, if any, in
    customary form and covering matters of the type customarily covered in
    "cold comfort" letters in connection with primary underwritten offerings;
    and (vi) deliver such documents and certificates as may be reasonably
    requested by the Majority Holders and the Managing Underwriters, if any,
    including those to evidence compliance with Section 4(k) and with any
    customary conditions contained in the underwriting agreement or other
    agreement entered into by the Issuers.  The foregoing actions set forth in
    clauses (iii), (iv), (v) and (vi) of this Section 4(r) shall be performed
    at (A) the effectiveness of such Registration Statement and each
    post-effective amendment thereto and (B) each closing under any
    underwriting or similar agreement as and to the extent required thereunder.

        (s)      In the case of any Exchange Offer Registration Statement, the
    Issuers shall, to the extent requested by any Purchaser, (i) make
    reasonably available for inspection by such Purchaser, and any attorney,
    accountant or other agent retained by such Purchaser, all relevant
    financial and other records, pertinent corporate documents and properties

    Issuers and their subsidiaries; (ii) cause the Issuers' officers,
    directors and employees to supply all relevant information reasonably
    requested by such Purchaser or any such attorney, accountant or agent in

    designated in writing by the Issuers, in good faith, as confidential at the
    time of delivery of such information shall be kept confidential by such
    Purchaser or any such attorney, accountant or agent, unless such disclosure
    is made in connection with a court proceeding or required by law, or such
    information becomes available to the public generally or through a third
    party without an accompanying obligation of confidentiality; (iii) make
    such representations and warranties to such Purchaser, in form, substance
    and scope as are customarily made by issuers to underwriters in primary
    underwritten offerings and covering matters including, but not limited to,
    those set forth in the Purchase Agreement; (iv) obtain opinions of counsel
    to the Issuers and updates thereof (which counsel and opinions (in form,

    and financial data are, or are required to be, included in the Registration
    Statement), addressed to such Purchaser, in customary form and covering

        5.       Registration Expenses.  The Issuers shall bear all expenses
incurred in connection with the performance of their obligations under Sections
2, 3 and 4 hereof and, in the event of any Shelf Registration Statement, will
reimburse the Holders for the reasonable fees and disbursements of one firm or
counsel designated by the Majority Holders to act as counsel for the Holders in
connection therewith, and, in the case of any Exchange Offer Registration
Statement, will reimburse the Initial Purchasers for the reasonable fees and
disbursements of one firm or counsel acting in connection therewith.


        6.       Indemnification and Contribution.  (a)  In connection with any
Registration Statement, the Issuers, jointly and severally, agree to indemnify
and hold harmless each Holder of Securities covered thereby (including each
Initial Purchaser and, with respect to any Prospectus delivery as contemplated
in Section 4(h) hereof, each Exchanging Dealer), the directors, officers,
employees and agents of each such Holder and each person who controls any such
Holder within the meaning of either the Act or the Exchange Act against any and
all losses, claims, damages or liabilities (including legal or other expenses
reasonably incurred in connection with investigating or defending same), joint
or several, to which they or any of them may become subject under the Act, the
Exchange Act or other Federal or state statutory law or regulation, at common
law or otherwise (collectively, "Losses"), insofar as such Losses (or actions
in respect thereof) arise out of or are based upon any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement as originally filed or in any amendment thereof, or in any
preliminary Prospectus or Prospectus, or in any amendment thereof or supplement
thereto, or arise out of or are based upon the omission or alleged omission to
state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, and agrees to reimburse each such
indemnified party, as incurred, for any legal or other expenses reasonably
incurred by them in connection with investigating or defending any such Loss or
action; provided, however, that the Issuers will not be liable to any Holder in
any case to the extent that any such loss, claim, damage or liability arises
out of or is based upon any such untrue statement or alleged untrue statement
or omission or alleged omission made therein in reliance upon and in conformity
with written information furnished to the Issuers by or on behalf of any such
Holder specifically for inclusion therein.


        The Issuers, jointly and severally, also agree to indemnify or
contribute to Losses of, as provided in Section 6(d), any underwriters of
Securities registered under a Shelf Registration Statement, their officers and
directors and





<PAGE>   16

                                      -16-


each person who controls such underwriters on substantially the same basis as
that of the indemnification of the Purchaser and the selling Holders provided
in this Section 6(a) and shall, if requested by any Holder, enter into an
underwriting agreement reflecting such agreement, as provided in Section 4(q)
hereof.

        (b)      Each Holder of Securities covered by a Registration Statement
(including each Purchaser and, with respect to any Prospectus delivery as
contemplated in Section 4(h) hereof, each Exchanging Dealer) severally agrees
to indemnify and hold harmless (i) the Issuers, (ii) each of their directors,
(iii) each of their respective officers who signs such Registration Statement
and (iv) each person who controls the Issuers within the meaning of either the
Act or the Exchange Act to the same extent as the foregoing indemnity from the
Issuers to each such Holder, but only with reference to written information
relating to such Holder furnished to the Issuers by or on behalf of such Holder
specifically for inclusion in the documents referred to in the foregoing
indemnity.  This indemnity agreement will be in addition to any liability which
any such Holder may otherwise have.


        (c)      Promptly after receipt by an indemnified party under this
Section 6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against the indemnifying
party under this Section 6, notify the indemnifying party in writing of the
commencement thereof; but the failure so to notify the indemnifying party (i)
will not relieve it from liability under paragraph (a) or (b) above unless and
to the extent it did not otherwise learn of such action and such failure
results in the forfeiture by the indemnifying party of substantial rights and
defenses and (ii) will not, in any event, relieve the indemnifying party from
any obligations to any indemnified party other than the indemnification
obligation provided in paragraph (a) or (b) above.  The indemnifying party
shall be entitled to appoint counsel of the indemnifying party's choice at the
indemnifying party's expense to represent the indemnified party in any action
for which indemnification is sought (in which case the indemnifying party shall
not thereafter be responsible for the fees and expenses of any separate counsel
retained by the indemnified party or parties except as set forth below);
provided, however, that such counsel shall be reasonably satisfactory to the
indemnified party.  Notwithstanding the indemnifying party's election to
appoint counsel to represent the indemnified party in an action, the
indemnified party shall have the right to employ separate counsel (including
local counsel), and the indemnifying party shall bear the reasonable fees,
costs and expenses of such separate counsel (and local counsel) if





<PAGE>   17

                                      -17-


(i) the use of counsel chosen by the indemnifying party to represent the
indemnified party would present such counsel with a conflict of interest, (ii)
the actual or potential defendants in, or targets of, any such action include
both the indemnified party and the indemnifying party and counsel to the
indemnified party shall have reasonably concluded that there may be legal
defenses available to such indemnified party and/or other indemnified parties
which are different from or additional to those available to the indemnifying
party, (iii) the indemnifying party shall not have employed counsel reasonably
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice of the institution of such action or (iv) the
indemnifying party shall authorize the indemnified party to employ separate
counsel at the expense of the indemnifying party.  An indemnifying party will
not, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any pending
or threatened claim, action, suit or proceeding in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim or action)
unless such settlement, compromise or consent includes an unconditional release
of each indemnified party from all liability arising out of such claim, action,
suit or proceeding.

        (d)      In the event that the indemnity provided in paragraph (a) or
(b) of this Section 6 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, then each applicable indemnifying party, in
lieu of indemnifying such indemnified party, shall have a joint and several
obligation to contribute to the aggregate losses, claims, damages and
liabilities (including legal or other expenses reasonably incurred in
connection with investigating or defending same) (collectively, "Losses") to
which such indemnified party may be subject in such proportion as is
appropriate to reflect the relative benefits received by such indemnifying
party, on the one hand, and such indemnified party, on the other hand, from the
Initial Placement and the Registration Statement which resulted in such Losses;
provided, however, that in no case shall any Initial Purchaser or any
subsequent Holder of any Security or New Security be responsible, in the
aggregate, for any amount in excess of the purchase discount or commission
applicable to such Security, or in the case of a New Security, applicable to
the Security which was exchangeable into such New Security, as set forth on the
cover page of the Final Memorandum, nor shall any underwriter be responsible
for any amount in excess of the underwriting discount or commission applicable
to the Securities purchased by such underwriter under the Registration
Statement which resulted in such Losses.  If the allocation provided by the





<PAGE>   18

                                      -18-


immediately preceding sentence is unavailable for any reason, the indemnifying
party and the indemnified party shall contribute in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of such indemnifying party, on the one hand, and such indemnified party,
on the other hand, in connection with the statements or omissions which
resulted in such Losses as well as any other relevant equitable considerations.
Benefits received by the Issuers shall be deemed to be equal to the proceeds
from the Initial Placement net of purchase discounts and commissions (before
deducting expenses) as set forth on the cover page of the Final Memorandum.
Benefits received by the Initial Purchasers shall be deemed to be equal to the
total purchase discounts and commissions as set forth on the cover page of the
Final Memorandum, and benefits received by any other Holders shall be deemed to
be equal to the value of receiving Securities or New Securities, as applicable,
registered under the Act.  Benefits received by any underwriter shall be deemed
to be equal to the total underwriting discounts and commissions, as set forth
on the cover page of the Prospectus forming a part of the Registration
Statement which resulted in such Losses.  Relative fault shall be determined by
reference to whether any alleged untrue statement or omission relates to
information provided by the indemnifying party, on the one hand, or by the
indemnified party, on the other hand.  The parties agree that it would not be
just and equitable if contribution were determined by pro rata allocation or
any other method of allocation which does not take account of the equitable
considerations referred to above.  Notwithstanding the provisions of this
paragraph (d), no person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.  For purposes
of this Section 6, each person who controls a Holder within the meaning of
either the Act or the Exchange Act and each director, officer, employee and
agent of such Holder shall have the same rights to contribution as such Holder,
and each person who controls the Issuers within the meaning of either the Act
or the Exchange Act, each officer of the Issuers who shall have signed the
Registration Statement and each director of the Issuers shall have the same
rights to contribution as the Company or the Subsidiary Guarantors
respectively, subject in each case to the applicable terms and conditions of
this paragraph (d).

        (e)      The provisions of this Section 6 will remain in full force and
effect, regardless of any investigation made by or on behalf of any Holder or
the Issuers or any of the officers, directors or controlling persons referred
to in Section 6 hereof, and will survive the sale by a Holder of securities
covered by a Registration Statement.

        7.       Miscellaneous.

        (a)      No Inconsistent Agreements.  The Issuers have not, as of the
date hereof, entered into, nor shall any of them, on or after the date hereof,
enter into, any agreement with respect to their securities that is inconsistent
with the rights granted to the Holders herein or otherwise conflicts with the
provisions hereof.

        (b)      Amendments and Waivers.  The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Issuers have obtained the
written consent of the Holders of at least a majority of the then outstanding
aggregate principal amount of Securities (or, after the consummation of any
Exchange Offer in accordance with Section 2 hereof, of New Securities);
provided that, with respect to any matter that directly or indirectly affects
the rights of any Initial Purchaser hereunder, the Issuers shall obtain the
written consent of each such Initial Purchaser against which such amendment,
qualification, supplement, waiver or consent is to be effective.
Notwithstanding the foregoing (except the foregoing proviso), a waiver or
consent to departure from the provisions hereof with respect to a matter that
relates exclusively to the rights of Holders whose securities are being sold
pursuant to a Registration Statement and that does not directly or indirectly
affect the rights of other Holders may be given by the Majority Holders,
determined on the basis of securities being sold rather than registered under
such Registration Statement.

        (c)      Notices.  All notices and other communications provided for or
permitted hereunder shall be made in writing by hand- delivery, first-class
mail, telex, telecopier, or air courier guaranteeing overnight delivery:

        (1)      if to a Holder, at the most current address given by such
    holder to the Issuers in accordance with the provisions of this Section
    7(c), which address initially is, with respect to each Holder, the address
    of such Holder maintained by the Registrar under the Indenture;

        (2)      if to you, initially at the respective addresses set forth in
    the Purchase Agreement; and

        (3)      if to the Issuers, initially at the address of the Company set
    forth in the Purchase Agreement with copies as indicated therein.





<PAGE>   20

                                      -20-


        All such notices and communications shall be deemed to have been duly
given when received.

        The Initial Purchasers or the Issuers by notice to the other may
designate additional or different addresses for subsequent notices or
communications.

        (d)      Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including, without the need for an express assignment or any consent
by the Issuers thereto, subsequent Holders of Securities and/or New Securities.
The Issuers hereby agree to extend the benefits of this Agreement to any Holder
of Securities and/or New Securities and any such Holder may specifically
enforce the provisions of this Agreement as if an original party hereto.

        (e)      Counterparts.  This agreement may be executed in any number of
counterparts and by the parties hereto in separate counterparts, each of which
when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

        (f)      Headings.  The headings in this agreement are for convenience
of reference only and shall not limit or otherwise affect the meaning hereof.

        (g)      Governing Law.  This agreement shall be governed by and
construed in accordance with the internal laws of the State of New York
applicable to agreements made and to be performed in said State.

        (h)      Severability.  In the event that any one of more of the
provisions contained herein, or the application thereof in any circumstances,
is held invalid, illegal or unenforceable in any respect for any reason, the
validity, legality and enforceability of any such provision in every other
respect and of the remaining provisions hereof shall not be in any way impaired
or affected thereby, it being intended that all of the rights and privileges of
the parties shall be enforceable to the fullest extent permitted by law.

        (i)      Securities Held by the Issuers, etc.  Whenever the consent or
approval of Holders of a specified percentage of principal amount of Securities
or New Securities is required hereunder, Securities or New Securities, as
applicable, held by the Issuers or their Affiliates (other than subsequent
Holders of Securities or New Securities if such subsequent Holders are deemed
to be Affiliates solely by reason of their holdings of





<PAGE>   21

                                      -21-


such Securities or New Securities) shall not be counted in determining whether
such consent or approval was given by the Holders of such required percentage.

        Please confirm that the foregoing correctly sets forth the agreement
between the Issuers and you.

                                            Very truly yours,

                                    Annex A

Each broker-dealer that receives New Securities for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with any resale of such New Securities.  The Letter of Transmittal
states that by so acknowledging and by delivering a prospectus, a broker-dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.  This Prospectus, as it may be amended or supplemented from
time to time, may be used by a broker-dealer in connection with resales of New
Securities received in exchange for Securities where such New Securities were
acquired by such broker-dealer as a result of market-making activities or other
trading activities.  The Issuers have agreed that they will make this
Prospectus available to any broker-dealer for use in connection with any such
resale, starting on the Expiration Date (as defined herein) and ending on the
close of business 180 days thereafter (or such later date as may be required by
Section 3(b) herein).  See "Plan of Distribution."

                                    Annex B

Each broker-dealer that receives New Securities for its own account in exchange
for Securities, where such Securities were acquired by such broker-dealer as a
result of market-making activities or other trading activities, must
acknowledge that it will deliver a prospectus in connection with any resale of
such New Securities.  See "Plan of Distribution."

                              PLAN OF DISTRIBUTION


        Each broker-dealer that receives New Securities for its own account
pursuant to the Exchange Offer must acknowledge that it will deliver a
prospectus in connection with any resale of such New Securities.  This
Prospectus, as it may be amended or supplemented from time to time, may be used
by a broker-dealer in connection with resales of New Securities received in
exchange for Securities where such Securities were acquired as a result of
market-making activities or other trading activities.  The Issuers have agreed
that, starting on the Expiration Date and ending on the close of business on
the 180th day after the Expiration Date, they will make this Prospectus, as
amended or supplemented, available to any broker-dealer for use in connection
with any such resale.  In addition, until __________, ____, all dealers
effecting transactions in the New Securities may be required to deliver a
prospectus.

        The Issuers will not receive any proceeds from any sale of New
Securities by broker-dealers.  New Securities received by broker-dealers for
their own account pursuant to the Exchange Offer may be sold from time to time
in one or more transactions in the over-the- counter market, in negotiated
transactions, through the writing of options on the New Securities or a
combination of such methods of resale, at market prices prevailing at the time
of resale, at prices related to such prevailing market prices or negotiated
prices.  Any such resale may be made directly to purchasers or to or through
brokers or dealers who may receive compensation in the form of commissions or
concessions from any such broker-dealer and/or the purchasers of any such New
Securities.  Any broker-dealer that resells New Securities that were received
by it for its own account pursuant to the Exchange Offer and any broker or
dealer that participates in a distribution of such New Securities may be deemed
to be an "underwriter" within the meaning of the Securities Act and any profit
of any such resale of New Securities and any commissions or concessions
received by any such persons may be deemed to be underwriting compensation
under the Securities Act.  The Letter of Transmittal states that by
acknowledging that it will deliver and by delivering a prospectus, a
broker-dealer will not be deemed to admit that it is an "underwriter" within
the meaning of the Securities Act.

        For a period of 180 days after the Expiration Date, the Issuers will
promptly send additional copies of this Prospectus and any amendment or
supplement to this Prospectus to any broker-dealer that requests such documents
in the Letter of Transmittal.  The Issuers have agreed to pay all expenses
incident to the Exchange Offer (including the expenses of one counsel for the
holders of the Securities) other than commissions or concessions

of any brokers or dealers and will indemnify the holders of the Securities
(including any broker-dealers) against certain liabilities, including
liabilities under the Securities Act.

and/or 508.
