     Oshkosh Truck Corporation, a Wisconsin corporation (the "Company"), hereby
offers (the "Exchange Offer"), upon the terms and subject to the conditions set
forth in this Prospectus and the accompanying Letter of Transmittal (the "Letter
of Transmittal"), to exchange up to an aggregate principal amount of
$100,000,000 of its new 8 3/4% Senior Subordinated Notes due 2008 (the "New
Senior Subordinated Notes" or "New Notes") for an equal principal amount of its
outstanding 8 3/4% Senior Subordinated Notes due 2008 (the "Senior Subordinated
Notes" or the "Notes"), in integral multiples of $1,000. The New Notes will be
fully and unconditionally guaranteed (the "New Note Guarantees") on a senior
subordinated basis by, and will be joint and several obligations of, Pierce
Manufacturing Inc., a Wisconsin corporation and a subsidiary of the Company,
Summit Performance Systems, Inc., a Wisconsin corporation and a subsidiary of

the New Notes will have been registered under the Securities Act of 1933, as
amended (the "Securities Act"), and (ii) holders of New Notes will not be

trustee (the "Trustee"). See "Description of the New Notes." There will be no
proceeds to the Company from this offering; however, pursuant to the
Registration Rights Agreement, the Company will bear certain offering expenses.

     The Company will accept for exchange any and all validly tendered Notes on
or prior to 12:00 midnight New York City time, on June 9, 1998, unless the
Exchange Offer is extended (the "Expiration Date"). Tenders of Notes may be
withdrawn at any time prior to 12:00 midnight, New York City time, on the
Expiration Date; otherwise such tenders are irrevocable. Firstar Trust Company
will act as Exchange Agent with respect to the Senior Subordinated Notes (in
such capacity, the "Exchange Agent") in connection with the Exchange Offer. The
Exchange Offer is not conditioned upon any minimum principal amount of Notes
being tendered for exchange, but is otherwise subject to certain customary
conditions.
    
 
     The Notes were sold by the Company on February 26, 1998 in a transaction
not registered under the Securities Act in reliance upon the exemption provided
in Section 4(2) of the Securities Act. The Notes were subsequently resold to
qualified institutional buyers in reliance upon Rule 144A under the Securities
Act or to persons outside the United States in reliance on Regulation S under
the Securities Act. Based on information provided by the Initial Purchaser (as
defined), the Company believes no Notes were resold to institutional accredited
investors in a manner exempt from registration under the Securities Act.
Accordingly, the Notes may not be reoffered, resold or otherwise transferred in
the United States unless registered under the Securities Act or unless an
applicable exemption from the registration requirements of the Securities Act is
available. The New Notes are being offered hereunder in order to satisfy certain
obligations of the Company under the Registration Rights Agreement. See "The
Exchange Offer."
 
     The New Senior Subordinated Notes will bear interest from February 26,
1998, the date of issuance of the Senior Subordinated Notes that are tendered in
exchange for the New Senior Subordinated Notes (or the most recent date to which
interest on such Notes has been paid) at a rate equal to 8 3/4% per annum.
Interest on the New Notes will be payable semiannually on March 1 and September
1 of each year (each an "Interest Payment Date"), commencing September 1, 1998.
The New Notes will mature on March 1, 2008, unless previously redeemed. The
Company will not be required to make any mandatory redemption or sinking fund
payment on the New Notes prior to maturity. The New Notes are redeemable at the
option of the Company, in whole or in part, at any time on or after March 1,
2003, at the redemption prices set forth herein, plus accrued and unpaid
interest, and Liquidated Damages (as defined), if any, to the date of
redemption. Prior to March 1, 2001, up to 35% of the initially outstanding
aggregate principal amount of New Senior Subordinated Notes may be redeemable at
the option of the Company, on one or more occasions, from the net proceeds of
public offerings of common stock of the Company, at a price of 108.75% of the
principal amount of the New Senior Subordinated Notes, together with accrued and
unpaid interest, and Liquidated Damages, if any, to the date of redemption;
provided that New Senior Subordinated Notes of an aggregate principle amount of
at least 65% of the initially outstanding aggregate principal amount of Senior
Subordinated Notes remains outstanding immediately after such redemption. See
"Description of the New Notes -- Optional Redemption."
 
     Upon the occurrence of a Change of Control (as defined), each Holder (as
defined) of New Notes may require the Company to repurchase all or a portion of
such Holder's New Notes at 101% of the aggregate principal amount of the New
Senior Subordinated Notes, together with accrued and unpaid interest, and
Liquidated Damages, if any, to the date of repurchase. The Senior Credit
Facility (as defined) prohibits the Company from purchasing any of the New Notes
prior to their maturity. Therefore, prior to effecting the repurchase described
above, the Company must either repay all amounts borrowed under and terminate
the Senior Credit Facility or obtain a consent to such repurchase from the
lenders under the Senior Credit Facility. There can be no assurance that upon a
Change in Control the Company would have sufficient assets to satisfy its
obligations to repurchase the New Notes. See "Description of the New
Notes -- Repurchase at the Option of Holders -- Change of Control."
 
     The New Notes will be general, unsecured obligations of the Company,
subordinated in right of payment to all present and future Senior Debt (as
defined) of the Company, including the Company's obligations under the Senior
Credit Facility. The New Notes will rank senior or pari passu in right of
payment to any future senior subordinated indebtedness of the Company and any
other subordinated indebtedness of the Company. The New Notes will be
unconditionally guaranteed, on a senior subordinated basis, by all of the
Company's domestic Restricted Subsidiaries (as defined) other than McNeilus
Financial Services, Inc. ("MFSI"). Each

                                                          (cover page continued)
 
Subsidiary Guarantee (as defined) will be a general unsecured obligation of each
Subsidiary Guarantor, subordinated in right of payment to all present and future
senior indebtedness of such Subsidiary Guarantor ("Subsidiary Guarantor Senior
Debt"). As of December 31, 1997, on a pro forma basis, after giving effect to
the Transactions (as defined), the Company would have had approximately $263.4
million of Senior Debt outstanding and the Subsidiary Guarantors would have had
approximately $2.9 million of Subsidiary Guarantor Senior Debt outstanding
(excluding guarantees of the Senior Credit Facility). On a pro forma basis, as
of December 31, 1997, the Company's total Indebtedness constituted approximately
75% of the Company's total capitalization. The Indenture generally permits the
incurrence of additional Senior Debt provided certain financial covenants are
met. See "Capitalization," "Description of Indebtedness -- Senior Credit
Facility" and "Description of the New Notes."
 
     Based on interpretations by the staff of the Securities and Exchange
Commission (the "Commission") set forth in no-action letters issued to third
parties, the Company believes that New Notes issued pursuant to the Exchange
Offer in exchange for Notes may be offered for resale, resold and otherwise
transferred by any holder thereof (other than any such holder which is an
"affiliate" of the Company 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 New Notes are acquired in the ordinary
course of such holder's business and that such holder does not intend to
participate in a distribution of such New Notes.
 
     Each broker-dealer that receives New Notes for its own account pursuant to
the Exchange Offer must acknowledge that it will deliver a prospectus in
connection with the initial resale of such New Notes. The Letter of Transmittal
delivered with this Prospectus 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 Notes received in exchange for Notes where
such Notes were acquired by such broker-dealer as a result of market-making
activities or other trading activities. The Company will make this Prospectus
available to any broker-dealer for use in connection with any such resale in
accordance with the terms of the Registration Rights Agreement.
 
     Any Holder who tenders in the Exchange Offer with the intention to
participate, or for purpose of participating, in a distribution of the New Notes
cannot rely on the position of the staff of the Commission enunciated in Exxon
Capital Holdings Corporation (available April 13, 1989), or Morgan Stanley &
Co., Inc. (available June 5, 1991) or similar no-action letters and, in the
absence of an exemption therefrom, must comply with the registration and
prospectus delivery requirements of the Securities Act in connection with the
resale of the New Notes. Failure to comply with such requirements in such
instance may result in such Holder incurring liability under the Securities Act
for which the Holder is not indemnified by the Company.
 
     The Company does not intend to list the New Notes on any securities
exchange, or to seek admission thereof to trading in the National Association of
Securities Dealers Automated Quotation System. BancAmerica Robertson Stephens
(the "Initial Purchaser") has advised the Company that it intends to make a
market in the New Notes; however, it is not obligated to do so and any
market-making may be discontinued at any time. As a result, the Company cannot
determine whether an active public market will develop for the New Notes.
 
     ANY NOTES NOT TENDERED AND ACCEPTED IN THE EXCHANGE OFFER WILL REMAIN
OUTSTANDING. TO THE EXTENT ANY NOTES ARE TENDERED AND ACCEPTED IN THE EXCHANGE
OFFER, A HOLDER'S ABILITY TO SELL UNTENDERED NOTES COULD BE ADVERSELY AFFECTED.
FOLLOWING CONSUMMATION OF THE EXCHANGE OFFER, THE HOLDERS OF NOTES WILL CONTINUE
TO BE SUBJECT TO THE EXISTING RESTRICTIONS UPON TRANSFER THEREOF AND THE COMPANY
WILL HAVE FULFILLED ONE OF ITS OBLIGATIONS UNDER THE REGISTRATION RIGHTS
AGREEMENT. HOLDERS OF NOTES WHO DO NOT TENDER THEIR NOTES GENERALLY WILL NOT
HAVE ANY FURTHER REGISTRATION RIGHTS UNDER THE REGISTRATION RIGHTS AGREEMENT OR
OTHERWISE. SEE "THE EXCHANGE OFFER -- CONSEQUENCES OF FAILURE TO EXCHANGE."

     The New Notes issued pursuant to this Exchange Offer generally will be
issued in the form of Global New Notes (as defined), which will be deposited
with, or on behalf of, The Depository Trust Company (the "Depository" or "DTC")
and registered in its name or in the name of Cede & Co., its nominee. Beneficial
interests in the Global New Notes representing the New Notes will be shown on,
and transfers thereof will be effected through, records maintained by the
Depository and its participants. Notwithstanding the foregoing, Notes held in
certificated form will be issued in exchange for the Global New Notes only on
the terms set forth in the Indenture. See "Description of the New
Notes -- Book-Entry, Delivery and Form."

     The following summary is qualified in its entirety by, and should be read
in conjunction with, the more detailed information and consolidated financial
statements and pro forma financial statements (including the notes thereto)
appearing elsewhere in this Prospectus. Unless otherwise indicated, all
references in this Prospectus to the Company's business and pro forma data give
effect to the Transactions (as defined). See "-- The Transactions." As used
herein, the "Company" refers to Oshkosh Truck Corporation, including Pierce
Manufacturing Inc. ("Pierce") and its other wholly-owned subsidiaries and, after
the Acquisition (as defined), McNeilus Companies, Inc. ("McNeilus"), and
"Oshkosh" refers to Oshkosh Truck Corporation and its wholly-owned subsidiaries
prior to the Acquisition.
 
                                  THE COMPANY
 
OVERVIEW
 
     The Company is a leading designer, manufacturer and marketer of a broad
range of fire apparatus and specialty commercial and military trucks under the
"Oshkosh," "Pierce," "McNeilus" and "MTM" trademarks. The Company's custom and
commercial fire apparatus include pumpers, aerial and ladder trucks, tankers,
heavy-duty rescue vehicles, wildland rough terrain response vehicles and
aircraft rescue and firefighting ("ARFF") vehicles. The Company's commercial
truck lines include refuse truck bodies, rear- and forward-discharge concrete
mixers and snow removal vehicles. As the leading manufacturer of severe-duty
heavy tactical trucks for the United States Department of Defense (the "DoD"),
the Company manufactures vehicles that perform a variety of demanding tasks,
such as hauling tanks, missile systems, ammunition, fuel and cargo for combat
units. For the twelve months ended December 31, 1997, on a pro forma basis, the
Company generated net sales of $1,011.3 million and EBITDA (as defined) of $79.4
million.
 
     The Company is focused on four principal markets:
 
     Fire Apparatus. The Company, through Pierce, is among the leading domestic
manufacturers of custom and commercial fire apparatus. The Company primarily
serves domestic governmental markets, but also sells fire apparatus to airports,
universities and large industrial companies. In addition, the Company sells fire
apparatus in international markets. Pierce's history of research and development
in consultation with firefighters has resulted in a broad product line that
features a wide range of innovative, high-quality custom and commercial
firefighting equipment with advanced fire suppression capabilities. The
Company's engineering expertise also allows it to design its vehicles to meet
stringent government regulations for safety and effectiveness.
 
     Refuse Truck Bodies. Management believes the Company, through McNeilus, is
a leading domestic manufacturer of refuse truck bodies for the waste services
industry. The Company manufactures a wide range of automated rear, front, side
and top loading refuse truck bodies, which the Company mounts on commercial
chassis. The Company sells its refuse vehicles primarily to commercial waste
management companies. Management believes the Company's refuse vehicles have a
reputation for efficient, cost-effective, dependable operation that supports the
Company's continued expansion into municipal and international markets.
 
     Concrete Mixers and Snow Removal Vehicles. Management believes the Company
is a leading domestic manufacturer of rear- and forward-discharge concrete
mixers. The Company sells rear- and forward-discharge concrete mixers and
portable concrete mixer plants to construction companies throughout the United
States and internationally. Management believes the Company is one of the only
domestic concrete mixer manufacturers that markets both rear- and
forward-discharge concrete mixers.
 
     The Company is also among the leading domestic manufacturers of snow
removal vehicles for airports. The Company's specially designed airport snow
removal vehicles can cast up to 4,000 tons of snow per hour and are used by some
of the largest airports in the United States, such as Denver International
Airport, LaGuardia International Airport, Minneapolis-St. Paul International
Airport and O'Hare International Airport. Management believes the reliability of
the Company's high performance snow removal vehicles contribute to its strong
market position.
 
                                        3
<PAGE>   7
 
     Defense Trucks. The Company has sold products to the DoD for over 70 years
and is the leading manufacturer of a broad line of severe-duty heavy tactical
trucks for the DoD. The Company's proprietary military all-wheel drive product
line includes: (i) the Palletized Load System ("PLS"), a highly mobile self-
contained truck and trailer system that loads and unloads a wide range of cargo
in a short period of time; (ii) the Heavy Expanded Mobility Tactical Truck
("HEMTT"), a cross-country cargo and supply carrier that, among other tasks, is
used for direct rearming of the Multiple Launch Rocket System, transport of
Patriot erector/launchers, resupply of field artillery ammunition and refueling
of tanks, trucks and helicopters in forward areas; (iii) the Heavy Equipment
Transporter ("HET"), the primary hauler of the M1A1 main battle tank and also a
hauler of other tanks, fighting and recovery vehicles, self-propelled howitzers
and construction equipment; and (iv) the Logistic Vehicle System ("LVS"), a
highly mobile cargo carrier with a maximum payload capacity of 20 tons. The
Company also exports its severe-duty heavy tactical trucks to approved foreign
customers.
 
COMPETITIVE STRENGTHS
 
     The following competitive strengths support the Company's business
strategy:
 
     Strong Market Positions. The Company has developed strong market positions
in each of its core businesses, which management attributes to the Company's
reputation for innovation, vehicle performance, reliability and customer
service. The Company has the leading share of the severe-duty heavy tactical
truck segment of the domestic defense truck market, and also believes it has a
leading share in: (i) custom and commercial fire apparatus, including pumpers,
aerial and ladder trucks, tankers, heavy duty rescue, wildland rough terrain
response vehicles and ARFF vehicles for the domestic fire apparatus market; (ii)
the domestic refuse truck body market; (iii) the domestic rear- and
forward-discharge concrete mixer markets; and (iv) the domestic airport snow
removal vehicle market. The Company intends to continue to strengthen its market
share by capitalizing on its strong reputation, introducing innovative products
and services and leveraging its extensive distribution capabilities.
 
     Extensive Distribution Capabilities. With the addition of the commercial
and municipal distribution capabilities of Pierce and McNeilus, the Company has
established an extensive domestic and international distribution system for
specialty trucks and truck bodies covering over 70 countries. In addition to its
network of dealers and distributors, the Company employs over 100 in-house sales
and service representatives. Management believes the Company's broad
distribution system has enabled the Company to: (i) maximize sales of new
products and technologies; (ii) become a benchmark for government customers
establishing their bid specifications; (iii) provide customer service on a
national and international scale; and (iv) reduce distribution expenses through
significant economies of scale.
 
     Flexible and Efficient Manufacturing. The Company believes it has
competitive advantages over larger truck manufacturers in its specialty truck
markets due to its manufacturing flexibility and custom fabrication
capabilities. For example, the Company has successfully configured its defense
truck and fire apparatus manufacturing plants for the simultaneous manufacture
of many different types and models of vehicles on the same assembly line at the
same time. In addition, the Company believes it has a competitive advantage over
smaller competitors due to its: (i) manufacturing in relatively higher volumes;
(ii) purchasing power across its product lines; and (iii) investing in fixturing
and robotics to improve efficiency and reduce costs.
 
     Quality Products and Customer Service. Oshkosh, Pierce and McNeilus have
each developed strong brand recognition based on their commitments to meet the
stringent product quality and reliability requirements of their customers and
the specialty truck markets they serve. The Company's commitment to product
quality is exemplified by the ISO 9001 certification of Oshkosh. Pierce is
targeting achievement of ISO 9001 certification in 1998. The Company also
achieves high quality customer service through its extensive service and parts
support program, which is available to domestic customers 365 days a year in all
product lines throughout the Company's distribution systems.
 
     Proprietary Components. The Company's advanced design and engineering
capabilities have contributed to the development of proprietary, severe-duty
components which enhance truck performance, reduce manufacturing costs and
strengthen customer relationships. These proprietary components include front
drive
                                        4
<PAGE>   8
 
and steer axles, transfer cases, cabs, the ALL-STEER electronic all-wheel
steering system, central tire inflation, independent suspension, the Sky-Arm
articulating aerial ladder and the McNeilus Auto Reach Arm. Management believes
these proprietary components provide the Company a competitive advantage by
increasing its vehicles' durability, operating efficiency and effectiveness. The
integration of many of these components across various product lines also
reduces the Company's costs to manufacture its products compared to
manufacturers who simply assemble purchased components.
 
BUSINESS STRATEGY
 
     The Company is focused on increasing its net sales, profitability and cash
flow by capitalizing on its competitive strengths. Key elements of the Company's
business strategy include:
 
     Focusing on Specialized Truck Markets. The Company plans to continue its
focus on those specialized truck and truck body markets where it has strong
market positions and where the Company can leverage synergies in purchasing,
manufacturing, technology and distribution. The Company's objective is to
achieve and maintain market leadership through internal growth and strategic
acquisitions. Management believes the higher sales volumes associated with
market leadership would allow the Company to continue to enhance productivity in
manufacturing operations, fund innovative product development and invest in
further expansion.
 
     Expanding Distribution and International Sales. The Company plans to add
new distribution capabilities for the municipal segment of the refuse truck body
market and in targeted geographic areas in the domestic fire apparatus market.
The Company intends to increase international sales beyond the $58.9 million pro
forma volume achieved in the twelve months ended December 31, 1997 by
introducing McNeilus refuse truck bodies, rear-discharge concrete mixers and
ready-mix batch plants to international markets and by continuing the expansion
of Pierce's international customer base through the Company's expanding
international distribution capabilities.
 
     Reducing Costs While Maintaining Quality. The Company actively benchmarks
its competitors' costs and best industry practices, and continuously seeks to
implement process improvements to increase cash flow and improve profitability.
With each of its acquisitions, the Company has established cost reduction
targets. At Pierce, the Company exceeded its first-year cost reduction target of
$3.4 million in fiscal 1997 as a result of consolidating facilities,
reengineering the manufacturing process and leveraging increased purchasing
power. The Company is planning for additional cost savings at Pierce in fiscal
1998. The Company intends to improve efficiencies after the acquisition of
McNeilus by taking advantage of the Company's greater purchasing power and by
developing additional manufacturing synergies across product lines.
 
     Introducing New Products. The Company has increased its emphasis on new
product development in recent years, and seeks to expand sales by introducing
new or improved products in its core markets, either through internal
development or strategic acquisition. For example, in December 1997, the Company
purchased the aerial fire apparatus product line of Nova Quintech, a division of
Nova Bus Corporation. This acquisition broadened Pierce's aerial product line
and is expected to provide Pierce with three new products in the first half of
calendar 1998.
 
     Diversifying DoD Contracts. The Company is seeking to diversify its
business with the DoD beyond its traditional contracts relating to the
manufacture of severe-duty heavy tactical trucks. Management believes the
Company has a reputation within the DoD for advanced engineering, quality
manufacturing and vehicle performance that will assist the Company in obtaining
contracts to provide other types of vehicles to the DoD. For example, the
Company was one of two manufacturers selected to participate in a DoD program to
produce upgraded medium-duty prototype vehicles for the Medium Tactical Truck
Remanufacture ("MTTR") program. The Company expects the testing and validation
phase for the MTTR program to conclude in the first half of 1998 and the initial
production contract to be awarded to the Company or the competing bidder in the
fourth quarter of 1998. The Company is also one of two manufacturers competing
for the DoD's Family of Medium Tactical Vehicles ("FMTV") contract. The Company
and the other participating manufacturer are currently preparing prototype FMTV
trucks for testing by the DoD.

                                THE TRANSACTIONS
 
THE ACQUISITION
 
     On December 8, 1997, Oshkosh entered into a definitive agreement (the
"Stock Purchase Agreement") pursuant to which, on February 26, 1998, it acquired
all of the outstanding capital stock of McNeilus and entered into related
non-compete and ancillary agreements for an aggregate acquisition price of
$250.0 million (the "Acquisition"). At November 30, 1997, McNeilus had
unrestricted cash of $17.7 million ($20.2 million less an estimated $2.5 million
required for capital and surplus at McNeilus' captive insurance subsidiary). The
Stock Purchase Agreement required, among other things, that the selling
stockholders of McNeilus prepay certain notes and purchase selected assets of
McNeilus, which provided net proceeds to Oshkosh of approximately $16.1 million.
As a result, management estimates that the effective cost to the Company in
connection with the Acquisition was approximately $216.2 million. Concurrently
with the consummation of the Acquisition, the Company consummated the Note
Offering (as defined), established the Senior Credit Facility, applied the net
proceeds from the Note Offering and the Senior Credit Facility to consummate the
Acquisition, refinanced existing Oshkosh indebtedness, paid fees and expenses
and established the Lease Financing Facility (as defined) (collectively, the
"Transactions").
 
THE SENIOR CREDIT FACILITY
 
     The Senior Credit Facility is comprised of a multi-tranche Term Loan
Facility (as defined) aggregating $225.0 million and a $100.0 million Revolving
Credit Facility (as defined). The Senior Credit Facility is guaranteed by all of
the Company's domestic Restricted Subsidiaries (other than MFSI). See
"Description of Indebtedness -- Senior Credit Facility."
 
THE LEASE FINANCING FACILITY
 
     Oshkosh/McNeilus Financial Services, Inc. (the "Leasing Partner"), a
subsidiary of MFSI, entered into a general partnership (the "Leasing
Partnership"), effective February 26, 1998, which offers lease financing to
customers of the Company and administers existing leases contributed to the
Leasing Partnership (the "Lease Financing Facility"). Indebtedness under the
Lease Financing Facility is secured by the underlying leases and assets of, and
is recourse to, the Leasing Partnership; such indebtedness is off-balance sheet
and non-recourse to the Company. See "Description of Indebtedness -- Lease
Financing Facility."

                                 whether or not such person is the Holder, is

                                 of business and that neither the Holder nor any

                                 understanding with any person to participate in

Withdrawal Rights.............   Tenders may be withdrawn at any time prior to
                                 12:00 midnight, New York City time, on the
                                 Expiration Date pursuant to the procedures
                                 described under "The Exchange Offer -- Terms of
                                 the Exchange Offer."
 
Acceptance of Notes and
Delivery of New Notes.........   The Company will accept for exchange any and
                                 all Notes that are properly tendered in the
                                 Exchange Offer prior to 12:00 midnight, New
                                 York City time, on the Expiration Date. The New

                                 will be delivered promptly following the
                                 Expiration Date. See "The Exchange Offer --

Federal Income Tax
Consequences..................   The issuance of the New Notes to Holders of the

                                 Prospectus will not constitute an exchange for
                                 federal income tax purposes. Consequently, no
                                 gain or loss would be recognized by Holders of
                                 the Notes upon receipt of the New Notes. See
                                 "The Exchange Offer -- Certain Federal Income
                                 Tax Consequences of the Exchange Offer."
 
Use of Proceeds...............   There will be no proceeds to the Company from
                                 the exchange of Notes pursuant to the Exchange
                                 Offer.

Effect on Holders of Notes....   As a result of the making of this Exchange
                                 Offer, the Company will have fulfilled certain
                                 of its obligations under the Registration
                                 Rights Agreement, and Holders of Notes who do
                                 not tender their Notes will generally not have
                                 any further registration rights under the
                                 Registration Rights Agreement or otherwise.
                                 Such Holders will continue to hold the
                                 untendered notes and will be entitled to all
                                 the rights and subject to all the limitations
                                 applicable thereto under the Indenture, except
                                 to the extent such rights or limitations, by
                                 their terms, terminate or cease to have further
                                 effectiveness as a result of the Exchange
                                 Offer. All untendered Notes will continue to be
                                 subject to certain restrictions on transfer.
                                 Accordingly, if any Notes are tendered and
                                 accepted in the Exchange Offer, the trading
                                 market for the untendered Notes could be
                                 adversely affected.

registered under the Securities Act and, therefore, will not bear legends
restricting the transfer thereof and (ii) the Holders of New Notes generally
will not be entitled to further registration rights under the Registration
Rights Agreement, which rights generally will be satisfied when the Exchange
Offer is consummated. The New Notes will evidence the same debt as the Notes and
will be entitled to the benefits of the Indenture. See "Description of the New

<PAGE>   14
 
                                 to repurchase such Holder's New Notes, in whole

                                 to the date of repurchase.
 
Ranking.......................   The New Notes will be general unsecured
                                 obligations of the Company, subordinated in
                                 right of payment to all present and future
                                 Senior Debt of the Company, including the
                                 Company's obligations under the Senior Credit
                                 Facility. The New Notes will rank pari passu
                                 with any future senior subordinated
                                 indebtedness of the Company and will rank
                                 senior to any other subordinated indebtedness
                                 of the Company. As of December 31, 1997, on a
                                 pro forma basis, the Company would have had
                                 approximately $263.4 million of Senior Debt
                                 outstanding and the Subsidiary Guarantors would
                                 have had approximately $2.9 million of
                                 Subsidiary Guarantor Senior Debt outstanding
                                 (excluding guarantees of the Senior Credit
                                 Facility).
 
Subsidiary Guarantees.........   The New Notes will be unconditionally
                                 guaranteed on a senior subordinated basis as to
                                 the payment of principal and interest and
                                 Liquidated Damages, if any, by the Subsidiary
                                 Guarantors. Each Subsidiary Guarantee will be a
                                 general unsecured obligation of such Subsidiary
                                 Guarantor, subordinated in right of payment to
                                 all Subsidiary Guarantor Senior Debt of such
                                 Subsidiary Guarantor.
 
Certain Covenants.............   The Indenture pursuant to which the New Notes
                                 will be issued will, among other things, limit
                                 the ability of the Company and its Restricted
                                 Subsidiaries to: (i) incur additional
                                 indebtedness or issue preferred stock; (ii)
                                 make certain Restricted Payments; (iii) grant
                                 Liens on assets; (iv) merge, consolidate or
                                 transfer substantially all of their assets; (v)
                                 enter into transactions with Affiliates; (vi)
                                 sell assets; (vii) sell capital stock of

                                 and leaseback transactions; (ix) impose
                                 restrictions on any Restricted Subsidiary's
                                 ability to pay dividends to the Company; (x)
                                 incur other senior subordinated indebtedness;

- -------------------------
(1) EBITDA represents income from operations plus depreciation and amortization.
    EBITDA also reflects the reduction of certain operating expenses that were
    incurred at the direction of former stockholders of McNeilus. Information
    concerning EBITDA has been included because management believes that EBITDA
    is generally accepted as providing useful information regarding a company's
    ability to service and/or incur debt. EBITDA should not be considered in
    isolation or as a substitute for net income, cash flows or other income or
    cash flow data prepared in accordance with generally accepted accounting
    principles or as a measure of a company's profitability or liquidity. The
    Company understands that, while EBITDA is frequently used by securities
    analysts in the evaluation of companies, EBITDA, as used herein, is not
    necessarily comparable to other similarly titled captions of other companies
    due to potential inconsistencies in the method of calculation. EBITDA is not
    intended as an alternative to cash flow from operating activities as a
    measure of liquidity, an alternative to net income as an indicator of
    operating performance or an alternative to any other measure of performance
    in conformity with generally accepted accounting principles. EBITDA margin
    percentage is calculated by dividing EBITDA by net sales.
 
     The calculation of pro forma EBITDA is set forth below (dollars in
     thousands):

(2) For purposes of the computation, the ratio of earnings to fixed charges has
    been calculated by dividing (i) income from continuing operations before
    income taxes and equity in leasing partnership pre-tax income plus fixed
    charges by (ii) fixed charges. Fixed charges are equal to interest expense
    plus the portion of the rent expense (one-third) estimated to represent
    interest expense.
 
(3) Cash interest expense represents total interest expense as reduced for
    interest expense relating to the amortization of deferred debt issuance
    costs. Amortization of deferred debt issuance costs equalled $1,226, $307
    and $1,226 for the fiscal year ended September 30, 1997, the three months
    ended December 31, 1997 and the twelve months ended December 31, 1997,
    respectively.

           SUMMARY HISTORICAL CONSOLIDATED FINANCIAL DATA FOR OSHKOSH
 
     The following table presents summary historical consolidated financial and
other data of Oshkosh as of and for the fiscal years ending September 30, 1997,
1996 and 1995, which have been derived from the audited consolidated financial
statements of Oshkosh, and as of and for the three months ended December 31,
1997 and 1996, which have been derived from the unaudited interim financial
statements of Oshkosh. The consolidated financial statements of Oshkosh for the
fiscal years 1997, 1996 and 1995 were audited by Ernst & Young LLP, independent
auditors. In the opinion of management, the interim consolidated financial
statements reflect all adjustments (consisting only of normal and recurring
adjustments) necessary to fairly present the information presented for such
periods. The results of operations for the three months ended December 31, 1997
are not necessarily indicative of the results of operations to be expected for
the full fiscal year. The following information should be read in conjunction
with "Management's Discussion and Analysis of Consolidated Financial Condition
and Results of Operations" and the historical consolidated financial statements
of Oshkosh and the related notes thereto included elsewhere herein.

(1) On September 18, 1996, Oshkosh acquired for $156,926 in cash all of the
    issued and outstanding stock of Pierce, a manufacturer and marketer of fire

    EBITDA should not be considered in isolation or as a substitute for net
    income, cash flows or other income or cash flow data prepared in accordance
    with generally accepted accounting principles or as a measure of a company's
    profitability or liquidity. The Company understands that, while EBITDA is
    frequently used by securities analysts in the evaluation of companies,
    EBITDA, as used herein, is not necessarily comparable to other similarly
    titled captions of other companies due to potential inconsistencies in the
    method of calculation. EBITDA is not intended as an alternative to cash flow
    from operating activities as a measure of liquidity, an alternative to net
    income as an indicator of operating performance or an alternative to any
    other measure of performance in conformity with generally accepted
    accounting principles. EBITDA margin percentage is calculated by dividing
    EBITDA by net sales.

                                  RISK FACTORS
 
     Holders of Notes should carefully consider the Risk Factors set forth below
prior to making a decision to tender into the Exchange Offer. This Prospectus
includes Forward-Looking Statements. Although the Company believes that its
plans, intentions and expectations reflected in such forward-looking statements
are reasonable, it can give no assurance that such plans, intentions or
expectations will be achieved. Important factors that could cause actual results
to differ materially from those included in or suggested by any Forward-Looking
Statements are set forth below and elsewhere in this Prospectus. All
Forward-Looking Statements attributable to the Company or persons acting on its
behalf are expressly qualified in their entirety by the Risk Factors set forth
below. See "Disclosure Regarding Forward-Looking Statements."
 
LEVERAGE AND DEBT SERVICE REQUIREMENTS
 
     The Company is and will continue to be highly leveraged as a result of the
substantial indebtedness it incurred in connection with the Transactions. On
December 31, 1997, on a pro forma basis, the Company would have had total
Indebtedness (as defined) of approximately $366.3 million and shareholders'
equity of approximately $123.0 million, and the Company's pro forma ratio of
earnings to fixed charges for the twelve months ended December 31, 1997 would
have been 1.6 to 1. Thus, on a pro forma basis, the Company's total Indebtedness
constituted approximately 75% of the Company's total capitalization. The Company
will be permitted to incur additional indebtedness in the future subject to
certain limitations. See "Capitalization," "Description of Indebtedness --
Senior Credit Facility" and "Description of the New Notes."
 
     The Company's ability to make scheduled payments of principal of, or to pay
the interest or Liquidated Damages, if any, on, or to refinance, its
indebtedness (including the New Notes) or to fund planned capital expenditures
will depend on its future performance, which, to a certain extent, is subject to
general economic, financial, competitive, legislative, regulatory and other
factors that are beyond its control. Based upon the current level of operations
of the Company, management believes that cash flow from operations and available
cash, together with available borrowings under the Senior Credit Facility, will
be adequate to meet the Company's future liquidity needs until the scheduled
expiration of the Senior Credit Facility, at which time the Company would expect
to replace the Senior Credit Facility. There can be no assurance, however, that
the Company's business will generate sufficient cash flow from operations, that
anticipated growth opportunities and operating improvements will be realized or
that future borrowings will be available under the Senior Credit Facility in an
amount sufficient to enable the Company to service its indebtedness, including
the New Notes, or to fund its other liquidity needs. The Senior Credit Facility
and the term loans thereunder mature prior to the maturity of the New Notes, and
there can be no assurance that the Company will be able to replace the Senior
Credit Facility, or refinance any other Indebtedness, on commercially reasonable
terms or at all. See "Management's Discussion and Analysis of Consolidated
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
     The degree to which the Company is and will continue to be leveraged as a
result of the Transactions could have important consequences to Holders of the
New Notes, including, but not limited to: (i) making it more difficult for the
Company to satisfy its obligations with respect to the New Notes; (ii)
increasing the Company's vulnerability to general adverse economic and industry
conditions; (iii) limiting the Company's ability to obtain additional financing
to fund future working capital, capital expenditures and other general corporate
requirements, or to fund future acquisitions; (iv) requiring the dedication of a
substantial portion of the Company's cash flow from operations to the payment of
principal of, and interest on, its indebtedness, thereby reducing the
availability of such cash flow to fund working capital, capital expenditures,
research and development or other general corporate purposes; (v) limiting the
Company's flexibility in planning for, or reacting to, changes in its business
and the industries it serves; and (vi) placing the Company at a competitive
disadvantage compared to less leveraged competitors. In addition, the Indenture
and the Senior Credit Facility contain financial and other restrictive covenants
that limit the ability of the Company to, among other things, borrow additional
funds. Failure by the Company to comply with such covenants could result in an
event of default which, if not cured or waived, could have a material adverse
effect on the Company's financial condition, results of operations and debt
service capability. See "Description of Indebtedness -- Senior Credit Facility"
and "Description of the New Notes."

<PAGE>   20
 
SUBORDINATION AND RANKING OF THE NEW NOTES AND SUBSIDIARY GUARANTEES
 
     The New Notes will be subordinated in right of payment to all current and
future Senior Debt of the Company, and the Subsidiary Guarantees will be
subordinated in right of payment to all current and future Subsidiary Guarantor
Senior Debt. Upon any distribution to creditors of the Company or any Subsidiary
Guarantor in a liquidation or dissolution of the Company or any Subsidiary
Guarantor or in a bankruptcy, reorganization, insolvency, receivership or
similar proceeding relating to the Company or such Subsidiary Guarantor or its
property, the holders of Senior Debt of the Company or Subsidiary Guarantor
Senior Debt, respectively, will be entitled to be paid in full before any
payment may be made with respect to the New Notes or any of the Subsidiary
Guarantees. The Company's obligations under the Senior Credit Facility are
secured by substantially all of the Company's assets and the stock of its
Restricted Subsidiaries, and the Indenture permits future Senior Debt to be
secured. In addition, the subordination provisions of the Indenture provide that
payments with respect to the New Notes and the Subsidiary Guarantees will be
blocked for an indefinite period so long as a payment default on Designated
Senior Debt (as defined) has occurred and is continuing and may be blocked for
up to 179 days each year in the event of certain non-payment defaults on
Designated Senior Debt. In the event of a bankruptcy, liquidation or
reorganization of the Company, Holders of the New Notes will participate ratably
with all holders of subordinated indebtedness of the Company that is deemed to
be of the same class as the New Notes, and potentially with all general
creditors of the Company other than holders of Senior Debt, based upon the
respective amounts owed to each holder or creditor, in the remaining assets of
the Company. In any of the foregoing events, there can be no assurance that
there would be sufficient assets in the Company or the Subsidiary Guarantors to
pay amounts due on the New Notes. As a result of the foregoing, Holders of the
New Notes may receive less, ratably, than the holders of Senior Debt. See
"Description of the New Notes -- Subordination."
 
     As of December 31, 1997, on a pro forma basis, the aggregate Senior Debt of
the Company (including borrowings under the Senior Credit Facility) would have
been approximately $263.4 million and the aggregate Subsidiary Guarantor Senior
Debt of the Subsidiary Guarantors would have been approximately $2.9 million
(excluding guarantees of the Senior Credit Facility), and approximately $78.8
million would have been available for additional borrowing under the terms of
the Senior Credit Facility. The Indenture permits the incurrence of additional
indebtedness, including Senior Debt, by the Company and its Subsidiaries in the
future, subject to certain limitations. See "Description of Indebtedness --
Senior Credit Facility," "Description of the New Notes -- Incurrence of
Indebtedness and Issuance of Preferred Stock."
 
UNCERTAINTY INHERENT IN U.S. GOVERNMENT CONTRACTS
 
     Approximately 29% of the Company's pro forma net sales for the twelve
months ended December 31, 1997 were made to the U.S. government under long-term
contracts and programs in the defense truck, fire apparatus and airport snow
removal markets. Companies engaged in supplying defense-related and other
equipment and services to U.S. government agencies are subject to certain
peculiar business risks. These risks include the ability of the U.S. government
to unilaterally suspend its contractors from receiving new contracts in the
event of certain violations of law or regulations. The Company has not faced any
such suspension, but it has been involved in U.S. government investigations of
various matters in the past, and although there are currently no ongoing
investigations involving the Company, there can be no assurance that the U.S.
government will not pursue matters previously investigated or that additional
investigations will not occur. The U.S. government also has the right to
terminate contracts either for its convenience or the default of the contractor.
In addition, certain costs and expenses are not allowable charges under U.S.
government contracts. The Company, as a U.S. government contractor, is subject
to financial audits and other reviews by the U.S. government of performance of,
and the accounting and general practices relating to, U.S. government contracts,
and like most large government contractors, the Company is audited and reviewed
on a continual basis. Costs and prices under such contracts may be subject to
adjustment based upon the results of such audits and reviews and the Company has
been required to pay adjustments in the past and is subject to a pending audit
seeking adjustments. There can be no assurance that the effects of audits,
reviews or governmental investigations will not have a material adverse effect
on the Company's financial condition, results of operations or debt service
capability. See "Business -- Government Contracts."
 
                                       17

     Congress usually appropriates funds for a given program on an annual basis
even though contract performance may take more than one year. Consequently, at
the outset of a major program, the contract is usually partially funded, and
additional monies are normally committed to the contract by the procuring agency
only as appropriations are made by Congress for future government fiscal years.
Failure of Congress to appropriate expected funding for the Company's programs
could have a material adverse effect on the Company's financial condition,
results of operations and debt service capability.
 
     Trends in DoD procurement are difficult to predict and subject to change,
and therefore there are substantial uncertainties and risks associated with the
Company's efforts to diversify its offerings to meet the possible future demands
of the DoD. The loss or significant curtailment of the Company's material U.S.
military contracts (including without limitation those identified in "Business
- -- Products and Markets"), or the failure to renew or replace material contracts
upon expiration or completion as a result of budget cuts or for other reasons,
could materially adversely affect the Company's financial condition, results of
operations and debt service capability.
 
     Substantially all of the Company's net sales to the DoD for the twelve
months ended December 31, 1997 were derived from fixed-price contracts. Although
the Company regularly fixes the supply costs of its contracts over the life of
the contract, inherent in such contracts is the risk that if a bid is submitted
and a contract is subsequently awarded, actual performance costs may exceed the
projected costs on which the fixed contract prices were based. To the extent
that actual costs exceed such projected costs, the Company's financial
condition, results of operations and debt service capability could be materially
adversely affected. See "Business -- Customers and Backlog" and "Business --
Government Contracts."
 
     The Company's existing contracts with the DoD for the PLS, HEMTT, HET and
LVS and for DoD vehicle parts expire in fiscal years 1999 and 2000, prior to the
maturity of the Notes. There can be no assurance such contracts will be extended
or renewed, or replaced with new contracts with the DoD. The Company is
currently competing for the MTTR program and FMTV contracts. There can be no
assurance that the Company will be awarded these or other new contracts with the
DoD, or that the Company will accurately project the costs of such contracts or
be able to fulfill such contracts at a profit to the Company. The Company's
failure to obtain these or other new contracts or to extend or replace those
expiring in fiscal years 1999 and 2000, or to accurately project costs on any
new contracts awarded by DoD, could have a material adverse effect on the
Company's financial condition, results of operations and debt service
capability.
 
DEPENDENCE ON KEY CUSTOMER; RISKS OF FURTHER REDUCTIONS OR CHANGES IN GOVERNMENT
EXPENDITURES
 
     Sales under contracts with the DoD, including U.S. government Foreign
Military Sales ("FMS") or under subcontracts that identified the DoD as the
ultimate purchaser, represented $290.8 million of the Company's pro forma net
sales for the twelve months ended December 31, 1997, down from $423.8 million in
Oshkosh's fiscal 1994. The Company expects fiscal 1998 sales to the DoD to
decrease an additional $20.0 to $30.0 million from fiscal 1997 levels. The U.S.
defense budget has declined significantly in recent years, resulting in a
slowing of new program starts, program delays and program cancellations. The
reduction in these budgets has caused many government contractors to experience
declining net sales, increased pressure on operating margins and, in some cases,
net losses. There can be no assurance the U.S. government defense budget or
programs for which the Company sells products or competes will not be further
reduced or that any such further reductions will not have a material adverse
effect on the Company's financial condition, results of operations or debt
service capability.
 
CYCLICAL NATURE OF CONSTRUCTION INDUSTRY
 
     The ready-mix concrete market served by the Company is highly cyclical and,
in large part, impacted by the strength of the economy generally, by prevailing
interest rates and by other factors which may have an effect on the level of
construction activity, either regionally or nationally. The U.S. construction
industry has generally been expanding in recent years, but has experienced
significant downturns in the past. Such downturns have materially and adversely
affected the net sales, profitability and cash flow of suppliers to the
construction industry, including the Company, and there can be no assurance that
such industry will not
 
                                       18
<PAGE>   22
 
experience similar downturns in the future. An economic recession may impact
substantially leveraged companies, such as the Company, more than similarly
situated companies with less leverage. A cyclical decline in overall customer
demand for concrete mixers could have a material adverse effect on the Company's
financial condition, results of operations and debt service capability.
 
CHALLENGES OF BUSINESS INTEGRATION; ACQUISITION STRATEGY
 
     Realization of the benefits of the business combination of Oshkosh with
McNeilus will require the integration of each company's sales and marketing,
distribution, manufacturing, engineering, finance and administrative
organizations. The successful integration of the companies will require
substantial attention from the companies' management teams. The diversion of
management attention, as well as any other difficulties which may be encountered
in the transaction and integration processes, could have an adverse impact on
the financial condition, results of operations or debt service capabilities of
the Company. Integrating the companies could, for example, result in a loss of
McNeilus or Oshkosh customers. There can be no assurance that Oshkosh will be
able to integrate the operations of Oshkosh and McNeilus successfully or that
the McNeilus business will continue to operate as profitably after the
Acquisition.
 
     In addition, there can be no assurance that the Company will be able to
identify additional acquisition candidates, obtain financing for future
acquisitions or consummate future acquisitions. If any such future acquisitions
are consummated, there can be no assurance that the Company will be able to
successfully integrate the acquired businesses or operate them profitably.
 
COMPETITION
 
     The Company operates in highly competitive industries. The Company competes
in the highly competitive fire apparatus and defense truck markets principally
on the basis of the lowest qualified bid. To submit a qualified bid, it must be
demonstrated that the fire apparatus or defense truck meets stringent
specifications, and for most defense truck contracts, passes extensive testing.
In addition, decreases in the DoD budget have resulted in a reduction in the
number and size of contracts, which has intensified the competition for
remaining available contracts. Substantial efforts are continually undertaken by
the Company and its competitors in order to maintain existing levels of defense
business and to succeed in bid competitions for available contracts. In the
refuse truck body and concrete mixer markets, the Company also faces intense
competition on the basis of price, innovation, quality, service and product
performance capabilities. As the Company seeks to expand its sales of refuse
truck bodies to municipal customers, the principal basis of competition for such
business will be lowest qualified bid. Several of the Company's competitors have
greater financial, marketing, manufacturing and distribution resources than the
Company. There can be no assurance that the Company's products will continue to
compete successfully with the products of competitors or that the Company will
be able to retain its customer base or to improve or maintain its profit margins
on sales to its customers, all of which could materially adversely affect the
Company's financial condition, results of operations and debt service
capability. See "Business -- Competition."
 
INTELLECTUAL PROPERTY MATTERS
 
     The Company's patents and licenses are important in the operation of its
business. Although the Company intends to protect its intellectual property
rights vigorously, there can be no assurance that it will be successful in doing
so. The Company has received, and may in the future receive, communications from
third parties claiming that one or more of the Company's products infringe upon
such party's intellectual property. If a third party were to make a valid claim,
the Company would likely need to obtain a license from such third party on
commercial terms, which would likely increase the Company's costs. Litigation,
which could result in substantial cost to, and diversion of resources of, the
Company could be necessary to enforce patents or other intellectual property
rights of the Company or to defend the Company against claimed infringement of
the rights of others. Infringement cases are brought against the Company from
time to time, and certain cases are presently pending. Although the Company
believes that its products do not infringe upon a valid claim of any patent and
that it has meritorious defenses to each presently pending lawsuit, it is not
possible to predict the outcomes of any of these lawsuits. The failure to obtain
necessary licenses or an adverse outcome in any
                                       19
<PAGE>   23
 
pending or future litigation relating to patent infringement or other
intellectual property matters could have a material adverse effect on the
Company's financial condition, results of operations and debt service
capability.
 
LABOR RELATIONS AND LABOR MARKET CONDITIONS
 
     Certain of the hourly employees at the Company's manufacturing facilities
in Oshkosh, Wisconsin, representing approximately 23% of the Company's employees
in the United States at December 31, 1997, are represented by the United Auto
Workers. None of the employees at any of the Company's other facilities are
represented by unions. A dispute between the Company and its employees could
result in a work stoppage that could have a material adverse effect on the
Company's financial condition, results of operations and debt service
capability. In addition, sustained economic growth in the United States has
resulted in lower unemployment and higher demand for labor in many locations,
including certain locations in which the Company operates. There can be no
assurance that future labor disputes, contract renegotiations or market
conditions will not materially impact the Company's operations or costs in the
future.
 
PRODUCT LIABILITY AND WARRANTY CLAIMS
 
     The Company's businesses expose it to potential product liability risks
that are inherent in the design, manufacture and sale of its products. While the
Company currently maintains what it believes to be suitable product liability
insurance, there can be no assurance that it will be able to maintain such
insurance on acceptable terms or that any such insurance will provide adequate
protection against potential liabilities. In the event of a claim against the
Company, a lack of sufficient insurance coverage could have a material adverse
effect on the Company and its business, financial condition, results of
operations and debt service capability. Moreover, even if the Company maintains
adequate insurance, any successful claim could materially and adversely affect
the reputation of the Company and its business, financial condition, results of
operations and debt service capability.
 
     The design, manufacture and marketing of the Company's products, as well as
the inclusion of parts from other suppliers in the Company's products,
necessarily entails an inherent risk of product warranty claims. For example,
Oshkosh recorded charges of $9.7 million in fiscal 1997 and $7.7 million in
fiscal 1996 relating to warranty claims from continuing operations. There can be
no assurance that the provisions currently maintained by the Company for such
claims will be adequate to protect it in the event a significant warranty claim
is successfully asserted against the Company beyond the scope of its historical
experience, and such a claim could have a material adverse effect on the
Company's business, financial condition, results of operations and debt service
capability. See "Business -- Legal Proceedings."
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to various federal, state, and local environmental
laws and regulations. The Company believes its operations are in material
compliance with such laws and regulations. However, there can be no assurance
that violations will not occur or be identified, or that environmental laws and
regulations will not change in the future, in a manner that could materially and
adversely affect the Company.
 
     Under certain circumstances, such environmental laws and regulations also
may impose joint and several liability for investigation and remediation of
contamination at locations owned or operated by the Company or its predecessors,
or at locations at which wastes or other contamination attributable to the
Company or its predecessors have come to be located. The Company can give no
assurance that such liability at facilities the Company currently owns or
operates, or at other locations, will not arise or be asserted against the
Company or entities for which it may be responsible. Such other locations could
include, for example, facilities formerly owned or operated by the Company (or
an entity or business that the Company has acquired), or locations to which
wastes generated by the Company (or an entity or business that the Company has
acquired) have been sent. Pierce has been identified as a potentially
responsible party under the federal Comprehensive Environmental Response,
Compensation and Liability Act of 1980, as amended ("CERCLA"), for investigation
and remediation costs at a site neither owned nor operated by the Company. In
addition, groundwater contamination has been identified at and about the
Company's Oshkosh, Wisconsin facility. At either of these
 
                                       20
<PAGE>   24
 
locations the Company could become subject to liability that, except under
certain circumstances, is joint and several for the total cost of investigating
and remediating the site. See "Business -- Environmental Matters" for additional
information relating to these locations. Such liability, or liability at
locations yet to be identified, could have a material adverse effect on the
Company's financial condition, results of operations and debt service
capability.
 
DEPENDENCE ON LIMITED OR SOLE SOURCE SUPPLIERS AND SUBCONTRACTORS
 
     The Company requires specific types of engines, transmissions, pumps,
flatracks and other parts for the manufacture of its products. The Company
obtains certain of these materials from limited or single source suppliers and
subcontractors with whom the Company has no long-term guaranteed supply
agreements. The Company has experienced problems with suppliers and
subcontractors and has incurred costs and expenses related to such problems. For
example, the Company has experienced production delays associated with its IPF
(as defined) subcontract with Steeltech (as defined), as discussed under the
caption "Management's Discussion and Analysis of Consolidated Financial
Condition and Results of Operations." The only sole source supplier of a
material part or component of the Company's products is the Allison Transmission
division of General Motors Corporation, which supplies the Company with
automatic transmissions used across the Company's product lines. There can be no
assurance that in the future significant disruption or termination of the supply
of these transmissions or other parts or components or a significant increase in
the cost of these transmissions or other parts or components will not occur and
result in a material adverse effect on the Company's financial condition,
results of operations or debt service capability.
 
INTERNATIONAL BUSINESS
 
     For the twelve months ended December 31, 1997, on a pro forma basis,
approximately 6% of the Company's net sales were attributable to products sold
outside of the United States, and expanded international sales are part of the
Company's growth strategy. Foreign sales are subject to various risks, including
exposure to currency fluctuations, political, religious and economic
instability, local labor market conditions, the imposition of foreign tariffs
and other trade barriers, and changes in governmental policies. The Company may
incur increased costs and experience delays or disruptions in product deliveries
and payments in connection with its foreign sales that could cause loss of
revenue. There can be no assurance that any such developments would not have a
material adverse effect on the Company's business, financial condition, results
of operations and debt service capability.
 
EXPOSURE TO INCREASES IN INTEREST RATES
 
     Amounts to be drawn under the Senior Credit Facility bear interest at
variable rates, and the Company has no present plan to enter into any hedging
arrangements that would have the effect of fixing its interest rates. A
substantial increase in interest rates could materially increase the interest
paid by the Company under the Senior Credit Facility and such increase could
have a material adverse effect on the Company's business, financial condition,
results of operation, and debt service. See Note (f) of Notes to Unaudited Pro
Forma Condensed Consolidated Financial Statements.
 
POSSIBLE INABILITY TO REPURCHASE NEW NOTES UPON A CHANGE OF CONTROL OFFER
 
     Upon a Change of Control, the Company will be required to offer to
repurchase all outstanding New Notes at 101% of the principal amount thereof
plus accrued and unpaid interest and Liquidated Damages, if any, to the date of
repurchase. However, there can be no assurance that sufficient funds will be
available at the time of any Change of Control to make any required repurchases
of New Notes tendered or that lenders under the Senior Credit Facility will
allow the Company to make such required repurchases, which are prohibited by the
terms of the Senior Credit Facility. Notwithstanding these provisions, subject
to certain limitations, the Company could enter into certain transactions,
including certain recapitalizations, that would not constitute a Change of
Control but would increase the amount of debt outstanding at such time. See
"Description of the New Notes -- Repurchase at the Option of Holders -- Change
of Control."
 
                                       21
<PAGE>   25
 
RESTRICTIONS IMPOSED BY TERMS OF THE COMPANY'S INDEBTEDNESS
 
     The Indenture restricts, among other things, the Company's and the
Subsidiary Guarantors' ability to incur additional indebtedness, create liens,
pay dividends or make other restricted payments, consummate certain asset sales,
enter into certain transactions with affiliates, incur indebtedness that is
subordinate in right of payment to any Senior Debt and senior in right of
payment to the New Notes or the Subsidiary Guarantees, as the case may be,
impose restrictions on the ability of a Restricted Subsidiary to pay dividends
or make certain payments to the Company, merge or consolidate with any other
person or sell, assign, transfer, lease, convey or otherwise dispose of all or
substantially all of the assets of the Company. In addition, the Senior Credit
Facility contains other and more restrictive covenants and prohibits the Company
from prepaying its other indebtedness (including the New Notes). See
"Description of Indebtedness -- Senior Credit Facility" and "Description of the
New Notes -- Certain Covenants." The Senior Credit Facility also requires the
Company to maintain specified financial ratios and satisfy certain financial
condition tests. The Company's ability to meet those financial ratios and tests
can be affected by events beyond its control, and there can be no assurance that
the Company will meet those tests. A breach of any of the foregoing covenants
could result in a default under the Senior Credit Facility and/or the Indenture.
Upon the occurrence of an event of default under the Senior Credit Facility, the
lenders thereunder could elect to declare all amounts outstanding under the
Senior Credit Facility, together with accrued and unpaid interest, to be
immediately due and payable, which would, in turn, result in an event of default
under the Indenture.
 
ABSENCE OF A PUBLIC MARKET; RESTRICTIONS ON TRANSFER
 
     The Notes are currently owned by a relatively small number of beneficial
owners. The Notes have not been registered under the Exchange Act and will be
subject to restrictions on transferability to the extent that they are not
exchanged for the New Notes. The New Notes will constitute a new issue of
securities with no established trading market. Although the New Notes will
generally be permitted to be resold or otherwise transferred by Holders who are
not affiliates of the Company without compliance with the registration
requirements under the Securities Act, the Company does not intend to list the
New Notes on any securities exchange or to seek admission thereof to trading in
the National Association of Securities Dealers Automated Quotation System.
Although BancAmerica Robertson Stephens has advised the Company that it
currently intends to make a market in the New Notes, it is not obligated to do
so and may discontinue such market making at any time without notice. If a
trading market does not develop or is not maintained, holders of the New Notes
may experience difficulty in reselling the New Notes or may be unable to sell
them at all. If a market for the New Notes develops, any such market may be
discontinued at any time. In addition, such market making activity will be
subject to the limits imposed by the Exchange Act. See "Description of the New
Notes -- Exchange Offer; Registration Rights." Accordingly, there can be no
assurance as to the development or liquidity of any market for the New Notes.
 
COMPLIANCE WITH EXCHANGE OFFER PROCEDURES; RESTRICTIONS ON RESALES
 
     Issuance of the New Notes in exchange for Notes pursuant to the Exchange
Offer will be made only after a timely receipt by the Exchange Agent of such
Notes, a properly completed and duly executed Letter of Transmittal and all
other required documents. Therefore, Holders of the Notes desiring to tender
such Notes in exchange for New Notes should allow sufficient time to ensure
timely delivery. The Company is under no duty to give notification of defects or
irregularities with respect to the tenders of Notes for exchange. Notes that are
tendered but not accepted will, following the consummation of the Exchange
Offer, continue to be subject to the existing restrictions upon transfer
thereof. In addition, any Holder of Notes who tenders in the Exchange Offer for
the purpose of participating in a distribution of the New Notes may be deemed to
have received restricted securities and, if so, will be required to comply with
the registration and prospectus delivery requirements of the Securities Act in
connection with any resale. Each broker-dealer that receives New Notes for its
own account in exchange for Notes, where such 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
the initial resale of such New Notes. To the extent that Notes are tendered and
accepted in
 
                                       22
<PAGE>   26
 
the Exchange Offer, the trading market for untendered and tendered but
unaccepted Notes could be adversely affected. See "The Exchange Offer."
 
FAILURE TO EXCHANGE NOTES FOR NEW NOTES
 
     Upon the consummation of the Exchange Offer, the Company will have
fulfilled one of its obligations under the Registration Rights Agreement, and
Holders of Notes who do not tender their Notes generally will not have any
further registration rights under the Registration Rights Agreement or
otherwise. Accordingly, any Holder of Notes that does not exchange his or her
Notes for New Notes will continue to hold the untendered Notes, which will
remain "restricted" securities under the Securities Act.
 
FRAUDULENT CONVEYANCE
 
     Under applicable provisions of federal bankruptcy law or comparable
provisions of state fraudulent transfer law, if, among other things, the Company
or any Subsidiary Guarantor, at the time it incurred the indebtedness evidenced
by the New Notes or its Subsidiary Guarantees, (i) (a) was or is insolvent or
rendered insolvent by reason of such incurrence or (b) was or is engaged in a
business or transaction for which the assets remaining with the Company or such
Subsidiary Guarantor constituted unreasonably small capital or (c) intended or
intends to incur, or believed or believes that it would incur, debts beyond its
ability to pay such debts as they mature; and (ii) the Company, or such
Subsidiary Guarantor received or receives less than reasonably equivalent value
or fair consideration for the incurrence of such indebtedness, then the New
Notes and the Subsidiary Guarantees, and any pledge or other security interest
securing such indebtedness, could be voided, or claims in respect of the New
Notes or the Subsidiary Guarantees could be subordinated to all other debts of
the Company or such Subsidiary Guarantor, as the case may be. In addition, the
payment of interest and principal by the Company pursuant to the New Notes or
the payments of amounts by a Subsidiary Guarantor pursuant to a Subsidiary
Guarantee could be voided and required to be returned to the person making such
payment, or to a fund for the benefit of the creditors of the Company or such
Subsidiary Guarantor, as the case may be.
 
     The measures of insolvency for purposes of the foregoing considerations
will vary depending upon the law applied in any proceeding with respect to the
foregoing. Generally, however, the Company or a Subsidiary Guarantor would be
considered insolvent if: (i) the sum of its debts, including contingent
liabilities, were greater than the saleable value of all of its assets at a fair
valuation or if the present fair saleable value of its assets were less than the
amount that would be required to pay its probable liability on its existing
debts, including contingent liabilities, as they become absolute and mature; or
(ii) it could not pay its debts as they become due.
 
     On the basis of historical financial information, recent operating history
and other factors, the Company and each Subsidiary Guarantor believes that,
after giving effect to the Indebtedness incurred in connection with the
Transactions, it will not be insolvent, will not have unreasonably small capital
for the business in which it is engaged and will not incur debts beyond its
ability to pay such debts as they mature. There can be no assurance, however, as
to what standard a court would apply in making such determinations or that a
court would agree with the Company's or the Subsidiary Guarantors' conclusions
in this regard.
 
CONTROL BY CERTAIN SHAREHOLDERS
 
     The Company has two classes of common equity: Common Stock and Class A
Common Stock. The voting rights of the Common Stock are limited to the election
of 25% of the Company's Board of Directors and such other voting rights required
by law. The Class A Common Stock has the right to elect 75% of the Company's
Board of Directors and to vote on any other matter brought to a vote of the
Company's shareholders. Therefore, effective control of the Company is vested in
the holders of the Class A Common Stock, which is closely held. See "Principal
Shareholders."
 
                                       23
<PAGE>   27
 
                               THE EXCHANGE OFFER
 
     The following discussion sets forth or summarizes the material terms of the
Exchange Offer, including those set forth in the Letter of Transmittal
distributed with this Prospectus. This summary is qualified in its entirety by
reference to the full text of the documents underlying the Exchange Offer,
copies of which are filed as exhibits to the Registration Statement of which
this Prospectus is a part and are incorporated by reference herein.
 
PURPOSE AND EFFECT OF THE EXCHANGE OFFER
 
     The Notes were sold by the Company to the Initial Purchaser on February 26,
1998, and were subsequently resold to either qualified institutional buyers
pursuant to Rule 144A under the Securities Act or to persons in transactions
outside the United States in reliance on Regulation S under the Securities Act.
In connection with the Note Offering, the Company entered into the Registration
Rights Agreement, which requires, among other things, that promptly following
the completion of the Note Offering, the Company and the Subsidiary Guarantors
(i) file with the Commission a registration statement under the Securities Act
with respect to an issue of new Notes of the Company identical in all material
respects to the Notes, (ii) use their best efforts to cause such registration
statement to become effective under the Securities Act and (iii) upon the
effectiveness of that registration statement, offer to the Holders of the Notes
the opportunity to exchange their Notes for a like principal amount of new
Notes, which would be issued without a restrictive legend and generally may be
reoffered and resold by the holder without restrictions or limitations under the
Securities Act (other than any such holder that is an "affiliate" of the Company
within the meaning of Rule 405 under the Securities Act). A copy of the
Registration Rights Agreement has been filed as an exhibit to the Registration
Statement of which this Prospectus is a part. This Prospectus, the Registration
Statement of which it is a part and the Exchange Offer are made pursuant to and
as required by the Registration Rights Agreement. The term "Holder" with respect
to the Exchange Offer means any person in whose name the Notes are registered on
the books of the Company or any other person who has obtained a properly
completed bond power from the registered holder.
 
     Because the Exchange Offer is for any and all Notes, the number of Notes
tendered and exchanged in the Exchange Offer will reduce the principal amount of
Notes outstanding. Following the consummation of the Exchange Offer, Holders of
the Notes who did not tender their Notes generally will not have any further
registration rights under the Registration Rights Agreement, and such Notes will
continue to be subject to certain restrictions on transfer. Accordingly, the
liquidity of the market for such Notes could be adversely affected. The Notes
are currently eligible for sale pursuant to Rule 144A through the PORTAL System
of the National Association of Securities Dealers, Inc. Because the Company
anticipates that most holders of Notes will elect to exchange such Notes for New
Notes due to the absence of restrictions on the resale of New Notes under the
Securities Act, the Company anticipates that the liquidity of the market for any
Notes remaining after the consummation of the Exchange Offer may be
substantially limited.
 
TERMS OF THE EXCHANGE OFFER
 
     Upon the terms and subject to the conditions set forth in this Prospectus
and in the Letter of Transmittal, the Company will accept any and all Notes
validly tendered and not withdrawn prior to 12:00 midnight, New York City time,
on the Expiration Date. The Company will issue $1,000 principal amount of New
Senior Subordinated Notes in exchange for each $1,000 principal amount of
outstanding Senior Subordinated Notes accepted in the Exchange Offer. Holders
may tender some or all of their Notes pursuant to the Exchange Offer. However,
Notes may be tendered only in integral multiples of $1,000.
 
     The form and terms of the New Notes are the same as the form and terms of
the Notes except that (i) the New Notes have been registered under the
Securities Act and hence will not bear legends restricting the transfer thereof
and (ii) the holders of the New Notes generally will not be entitled to certain
rights under the Registration Rights Agreement, which rights generally will
terminate upon consummation of the Exchange Offer. The New Notes will evidence
the same debt as the Notes and will be entitled to the benefits of the
Indenture.
 
                                       24
<PAGE>   28
 
     Holders of Notes do not have any appraisal or dissenters' rights under the
Wisconsin Business Corporation Law or the Indenture in connection with the
Exchange Offer. The Company intends to conduct the Exchange Offer in accordance
with the applicable requirements of the Exchange Act and the rules and
regulations of the Commission thereunder, including Rule 14e-1 thereunder.
 
     The Company shall be deemed to have accepted validly tendered Notes when,
as and if the Company has given oral or written notice thereof to the Exchange
Agent. The Exchange Agent will act as agent for the tendering Holders for the
purpose of receiving the New Notes from the Company.
 
     If any tendered Notes are not accepted for exchange because of an invalid
tender, the occurrence of certain other events set forth herein or otherwise,
the certificates for any such unaccepted Notes will be returned, without
expense, to the tendering Holder thereof as promptly as practicable after the
Expiration Date.
 
     Holders who tender Notes in the Exchange Offer will not be required to pay
brokerage commissions or fees or, subject to the instructions in the Letter of
Transmittal, transfer taxes with respect to the exchange of Notes pursuant to
the Exchange Offer. The Company will pay all charges and expenses, other than
transfer taxes in certain circumstances, in connection with the Exchange Offer.
See "-- Fees and Expenses."
 
EXPIRATION DATE; EXTENSIONS; AMENDMENTS
 
   
     The term "Expiration Date" shall mean 12:00 midnight, New York City time,
on June 9, 1998, unless the Company, in its sole discretion, extends the
Exchange Offer, in which case the term "Expiration Date" shall mean the latest
date and time to which the Exchange Offer is extended.
    
 
     To extend the Exchange Offer, the Company will notify the Exchange Agent of
any extension by oral or written notice, followed by a public announcement
thereof no later than 9:00 a.m., New York City time, on the next business day
after the previously scheduled expiration date.
 
     The Company reserves the right, in its reasonable judgment, (i) to delay
accepting any Notes, to extend the Exchange Offer or to terminate the Exchange
Offer if any of the conditions set forth below under "-- Conditions" shall not
have been satisfied, by giving oral or written notice of such delay, extension
or termination to the Exchange Agent or (ii) to amend the terms of the Exchange
Offer in any manner. Any such delay in acceptance, extension, termination or
amendment will be followed as promptly as practicable by a public announcement
thereof. If the Exchange Offer is amended in a manner determined by the Company
to constitute a material change, the Company will promptly disclose such
amendment by means of a prospectus supplement that will be distributed to the
registered Holders, and, depending upon the significance of the amendment and
the manner of disclosure to the registered Holders, the Company will extend the
Exchange Offer for five to ten business days if the Exchange Offer would
otherwise expire during such five to ten business-day period.
 
     If the Company does not consummate the Exchange Offer, or, in lieu thereof,
the Company does not file and cause to become effective a resale shelf
registration for the Notes within the time periods set forth therein, Liquidated
Damages will accrue and be payable on the Notes either temporarily or
permanently. See "Description of the New Notes -- Exchange Offer; Registration
Rights."
 
INTEREST ON NEW NOTES
 
     The New Senior Subordinated Notes will bear interest from February 26,
1998, the date of issuance of the Notes that are tendered in exchange for the
New Notes (or the most recent date to which interest on such Notes has been
paid). Accordingly, Holders of Notes that are accepted for exchange will not
receive interest that is accrued but unpaid on the Notes at the time of tender,
but such interest will be payable on the first March 1 or September 1, as the
case may be, after the Expiration Date. Interest on the New Notes will be
payable semiannually on each March 1 and September 1, commencing on September 1,
1998.
 
                                       25
<PAGE>   29
 
PROCEDURES FOR TENDERING
 
     Only a holder of Notes may tender such Notes in the Exchange Offer. To
tender in the Exchange Offer, a Holder must complete, sign and date the relevant
Letter of Transmittal, or a facsimile thereof, have the signatures thereon
guaranteed if required by the Letter of Transmittal, and mail or otherwise
deliver such Letter of Transmittal or such facsimile, together with the Notes
and any other required documents, to the Exchange Agent so as to be received by
the Exchange Agent at the address set forth below prior to 12:00 midnight, New
York City time, on the Expiration Date. The Letter of Transmittal must be used
to tender Notes. Delivery of the Notes may be made by book-entry transfer in
accordance with the procedures described below. Confirmation of such book-entry
transfer must be received by the Exchange Agent prior to the Expiration Date.
 
     By executing the Letter of Transmittal, each Holder will make to the
Company the representation set forth below in the second paragraph under the
heading "-- Resale of New Notes."
 
     The tender by a Holder and the acceptance thereof by the Company will
constitute an agreement between such Holder and the Company in accordance with
the terms and subject to the conditions set forth herein and in the Letter of
Transmittal.
 
     THE METHOD OF DELIVERY OF NOTES AND THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED DOCUMENTS TO THE EXCHANGE AGENT IS AT THE ELECTION AND RISK OF THE
HOLDER. INSTEAD OF DELIVERY BY MAIL, IT IS RECOMMENDED THAT HOLDERS USE AN
OVERNIGHT OR HAND DELIVERY SERVICE. IF DELIVERY BY MAIL IS NEVERTHELESS USED,
REGISTERED MAIL IS RECOMMENDED. IN ALL CASES, SUFFICIENT TIME SHOULD BE ALLOWED
TO ASSURE DELIVERY TO THE EXCHANGE AGENT BEFORE THE EXPIRATION DATE. NO LETTER
OF TRANSMITTAL OR NOTES SHOULD BE SENT TO THE COMPANY. HOLDERS MAY REQUEST THEIR
RESPECTIVE BROKERS, DEALERS, COMMERCIAL BANKS, TRUST COMPANIES OR NOMINEES TO
EFFECT THE ABOVE TRANSACTIONS FOR SUCH HOLDERS.
 
     Any beneficial owner whose Notes are registered in the name of a broker,
dealer, commercial bank, trust company or other nominee and who wishes to tender
should contact the registered Holder promptly and instruct such registered
Holder to tender on such beneficial owner's behalf.
 
     Signatures on the Letter of Transmittal or a notice of withdrawal, as the
case may be, must be guaranteed by an Eligible Institution (as defined) unless
the Notes tendered pursuant thereto are tendered (i) by a registered Holder who
has not completed the box entitled "Special Registration Instructions" or
"Special Delivery Instructions" on the Letter of Transmittal or (ii) for the
account of an Eligible Institution. In the event that signatures on a Letter of
Transmittal or a notice of withdrawal, as the case may be, are required to be
guaranteed, such guarantee must be by a member firm of a registered national
securities exchange or of the National Association of Securities Dealers, Inc.,
a commercial bank or trust company having an office or correspondent in the
United States or an "eligible guarantor institution" within the meaning of Rule
17Ad-15 under the Exchange Act (an "Eligible Institution").
 
     If the Letter of Transmittal is signed by a person other than the
registered Holder of any Notes listed therein, such Notes must be endorsed or
accompanied by a properly completed bond power, signed by such registered Holder
as such registered Holder's name appears on such Notes with the signature
thereon guaranteed by an Eligible Institution.
 
     If the Letter of Transmittal or any Notes or bond powers 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,
evidence satisfactory to the Company of their authority to so act must be
submitted with the Letter of Transmittal.
 
     The Company understands that the Exchange Agent will make a request
promptly after the date of this Prospectus to establish accounts with respect to
the Notes at the Depository for the purpose of facilitating the Exchange Offer,
and subject to the establishment thereof, any financial institution that is a
participant in the
 
                                       26
<PAGE>   30
 
Depository's system may make book-entry delivery of the Notes by causing the
Depository to transfer such Notes into the Exchange Agent's account with respect
to the Notes in accordance with the Depository's procedures for such transfer.
Although delivery of the Notes may be effected through book-entry transfer into
the Exchange Agent's account at the Depository, an appropriate Letter of
Transmittal properly completed and duly executed with any required signature
guarantee and all other required documents must in each case be transmitted to
and received or confirmed by the Exchange Agent at its address set forth below
on or prior to the Expiration Date, or, if the guaranteed delivery procedures
described below are complied with, within the time period provided under such
procedures. Delivery of documents to the Depository does not constitute delivery
to the Exchange Agent.
 
     All questions as to the validity, form, eligibility (including time of
receipt), acceptance of tendered Notes and withdrawal of tendered Notes will be
determined by the Company in its sole discretion, which determination will be
final and binding. The Company reserves the absolute right to reject any and all
Notes not properly tendered or any Notes the Company's acceptance of which
would, in the opinion of counsel for the Company, be unlawful. The Company also
reserves the right to waive any defects, irregularities or conditions of tender
as to particular Notes. The Company's interpretation of the terms and conditions
of the Exchange Offer (including the instructions in the Letter of Transmittal)
will be final and binding on all parties. Unless waived, any defects or
irregularities in connection with tenders of Notes must be cured within such
time as the Company shall determine. Although the Company intends to notify
Holders of defects or irregularities with respect to tenders of Notes, none of
the Company, the Exchange Agent or any other person shall incur any liability
for failure to give such notification. Tenders of Notes will not be deemed to
have been made until such defects or irregularities have been cured or waived.
Any Notes received by the Exchange Agent that are not properly tendered and as
to which the defects or irregularities have not been cured or waived will be
returned by the Exchange Agent to the tendering Holders, unless otherwise
provided in the Letter of Transmittal, as soon as practicable following the
Expiration Date.
 
GUARANTEED DELIVERY PROCEDURES
 
     Holders who wish to tender their Notes and (i) whose New Notes are not
immediately available, (ii) who cannot deliver their Notes, the Letter of
Transmittal or any other required documents to the relevant Exchange Agent or
(iii) who cannot complete the procedures for book-entry transfer, prior to the
Expiration Date, may effect a tender if:
 
          (a) the tender is made through an Eligible Institution;
 
          (b) prior to the Expiration Date, the Exchange Agent receives from
     such Eligible Institution a properly completed and duly executed Notice of
     Guaranteed Delivery (by facsimile transmission, mail or hand delivery)
     setting forth the name and address of the Holder, the certificate number(s)
     of such Notes and the principal amount of Notes tendered, stating that the
     tender is being made thereby and guaranteeing that, within three New York
     Stock Exchange trading days after the Expiration Date, the Letter of
     Transmittal (or facsimile thereof), together with the certificate(s)
     representing the Notes (or a confirmation of book-entry transfer of such
     Notes into the Exchange Agent's account at the Depository) and any other
     documents required by the Letter of Transmittal, will be deposited by the
     Eligible Institution with the Exchange Agent; and
 
          (c) such properly completed and executed Letter of Transmittal (or
     facsimile thereof), as well as the certificate(s) representing all tendered
     Notes in proper form for transfer (or a confirmation of book-entry transfer
     of such Notes into the Exchange Agent's account at the Depository) and all
     other documents required by the Letter of Transmittal, are received by the
     Exchange Agent within three New York Stock Exchange trading days after the
     Expiration Date.
 
     Upon request to the Exchange Agent, a Notice of Guaranteed Delivery will be
sent to Holders who wish to tender their Notes according to the guaranteed
delivery procedures set forth above.

WITHDRAWALS OF TENDERS
 
     Except as otherwise provided herein, tenders of Notes may be withdrawn at
any time prior to 12:00 midnight New York City time, on the Expiration Date.
 
     To withdraw a tender of Notes in the Exchange Offer, a written or facsimile
transmission notice of withdrawal must be received by the Exchange Agent at its
address set forth herein prior to 12:00 midnight New York City time, on the
Expiration Date. Any such notice of withdrawal must (i) specify the name of the
person having deposited the Notes to be withdrawn (the "Depositor"), (ii)
identify the Notes to be withdrawn (including the certificate number(s) and
principal amount of such Notes, or, in the case of Notes transferred by
book-entry transfer, the name and number of the account at the Depository to be
credited), (iii) be signed by the Holder in the same manner as the original
signature on the Letter of Transmittal by which such Notes were tendered
(including any required signature guarantees) or be accompanied by documents of
transfer sufficient to have the Trustee with respect to the Notes register the
transfer of such Notes into the name of the person withdrawing the tender, and
(iv) specify the name in which any such Notes are to be registered, if different
from that of the Depositor. All questions as to the validity, form and
eligibility (including time or receipt) of such notices will be determined by
the Company, whose determination shall be final and binding on all parties. Any
Notes so withdrawn will be deemed not to have been validly tendered for purposes
of the Exchange Offer and no New Notes will be issued with respect thereto
unless the Notes so withdrawn are validly retendered. Any Notes which have been
tendered but which are not accepted for exchange will be returned to the Holder
thereof without cost to such Holder as soon as practicable after withdrawal,
rejection of tender or termination of the Exchange Offer. Properly withdrawn
Notes may be retendered by following one of the procedures described above under
"-- Procedures for Tendering" at any time prior to the Expiration Date.
 
CONDITIONS
 
     Notwithstanding any other term of the Exchange Offer, the Company shall not
be required to accept for exchange, or to exchange New Notes for, any Notes, and
may terminate or amend the Exchange Offer as provided herein before the
acceptance of such Notes, if any law, statute, rule, regulation or
interpretation by the staff of the Commission is proposed, adopted or enacted,
which, in the reasonable judgment of the Company, might materially impair the
ability of the Company to proceed with the Exchange Offer or materially impair
the contemplated benefits of the Exchange Offer to the Company.
 
     If the Company determines in its reasonable judgment that any of the
conditions are not satisfied, the Company may (i) refuse to accept any Notes and
return all tendered Notes to the tendering Holders, (ii) extend the Exchange
Offer and retain all Notes tendered prior to the expiration of the Exchange
Offer, subject, however, to the rights of Holders to withdraw such Notes (see
"Withdrawals of Tenders") or (iii) waive such unsatisfied conditions with
respect to the Exchange Offer and accept all properly tendered Notes which have
not been withdrawn. If such waiver constitutes a material change to the Exchange
Offer, the Company will promptly disclose such waiver by means of a prospectus
supplement that will be distributed to the registered holders, and, depending
upon the significance of the waiver and the manner of disclosure to the
registered Holders, the Company will extend the Exchange Offer for a period of
five to ten business days if the Exchange Offer would otherwise expire during
such five to ten business-day period.
 
EXCHANGE AGENT
 
     Firstar Trust Company will act as Exchange Agent for the Exchange Offer
with respect to the Notes (the "Exchange Agent").

     Questions and requests for assistance, requests for additional copies of
this Prospectus or of the Letter of Transmittal for the Notes and requests for
copies of Notice of Guaranteed Delivery should be directed to the Exchange
Agent, addressed as follows:
 
     By Registered or Certified Mail, Overnight Mail or Courier Service or in
Person By Hand:
 
               Firstar Trust Company
           1555 North River Center Drive
           Suite 301

           Attention: Pamela Warner
 
     By Facsimile:
 
           (414) 905-5049
 
FEES AND EXPENSES
 
     The expenses of soliciting tenders will be borne by the Company. The
principal solicitation is being made by mail; however, additional solicitation
may be made by telegraph, telephone, facsimile or in person by officers and
regular employees of the Company and its affiliates.
 
     The Company has not retained any dealer-manager in connection with the
Exchange Offer and will not make any payments to brokers or other persons
soliciting acceptances of the Exchange Offer. The Company, however, will pay the
Exchange Agent reasonable and customary fees for its services and will reimburse
it for its reasonable out-of-pocket expenses in connection therewith and pay
other registration expenses, including fees and expenses of the Trustee, filing
fees, blue sky fees and printing and distribution expenses.
 
     The Company will pay all transfer taxes, if any, applicable to the exchange
of the Notes pursuant to the Exchange Offer. If, however, certificates
representing the New Notes or the Notes for principal amounts not tendered or
accepted for exchange are to be delivered to, or are to be issued in the name
of, any person other than the registered Holder of the Notes tendered, or if
tendered 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 exchange of the Notes pursuant to the Exchange Offer, then
the amount of any such transfer taxes (whether imposed on the registered Holder
or any other person) will be payable by the tendering Holder.
 
ACCOUNTING TREATMENT
 
     The New Notes will be recorded at the same carrying value as the Notes,
which is the aggregate principal amount of the Notes, as reflected in the
Company's accounting records on the date of exchange. Accordingly, no gain or
loss for accounting purposes will be recognized in connection with the Exchange
Offer. The expenses of the Exchange Offer will be amortized over the term of the
New Notes.
 
RESALE OF NEW NOTES
 
     Based on interpretations by the staff of the Commission set forth in
no-action letters issued to third parties, the Company believes that New Notes
issued pursuant to the Exchange Offer in exchange for Notes may be offered for
resale, resold and otherwise transferred by any Holder of such New Notes (other
than any such Holder which is an "affiliate" of the Company 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 New
Notes are acquired in the ordinary course of such Holder's business and such
Holder does not intend to participate, and has no arrangement or understanding
with any person to participate, in a distribution of such New Notes. Any Holder
who tenders in the Exchange Offer with the intention to participate, or for the
purpose of participating, in a distribution of the New Notes may not rely on the
position of the staff of the Commission enunciated in Exxon Capital Holdings
Corporation (available April 13, 1989) and Morgan Stanley & Co., Incorporated
(available June 5, 1991), or similar no-action letters, but rather must comply
with the registration and prospectus delivery requirements of the Securities Act
in connection with any resale
 
                                       29
<PAGE>   33
 
transaction. In addition, any such resale transaction should be covered by an
effective registration statement containing the selling security holder's
information required by Item 507 or 508 of Regulation S-K of the Securities Act,
as applicable. Each broker-dealer that receives New Notes for its own account in
exchange for Notes, where such Notes were acquired by such broker-dealer as a
result of market-making activities or other trading activities, may be a
statutory underwriter and must acknowledge that it will deliver a prospectus in
connection with any resale of such New Notes.
 
     By tendering in the Exchange Offer, each Holder will represent to the
Company that, among other things, (i) the New Notes acquired pursuant to the
Exchange Offer are being obtained in the ordinary course of business of the
person receiving such New Notes, whether or not such person is a Holder, (ii)
neither the Holder nor any such other person has an arrangement or understanding
with any person to participate in a distribution of such New Notes and (iii) the
Holder and such other person acknowledge that if they participate in the
Exchange Offer for the purpose of distributing the New Notes (a) they must, in
the absence of an exemption therefrom, comply with the registration and
prospectus delivery requirements of the Securities Act in connection with any
resale of the New Notes and cannot rely on the no-action letters referenced
above and (b) failure to comply with such requirements in such instance could
result in such Holder incurring liability under the Securities Act for which
such Holder is not indemnified by the Company. Further, by tendering in the
Exchange Offer, each Holder that may be deemed an "affiliate" (as defined under
Rule 405 of the Securities Act) of the Company will represent to the Company
that such Holder understands and acknowledges that the New Notes may not be
offered for resale, resold or otherwise transferred by that Holder without
registration under the Securities Act or an exemption therefrom.
 
CONSEQUENCES OF FAILURE TO EXCHANGE
 
     As a result of the making of this Exchange Offer, the Company will have
fulfilled one of its obligations under the Registration Rights Agreement, and
Holders of Notes who do not tender their Notes generally will not have any
further registration rights under the Registration Rights Agreement or
otherwise. Accordingly, any Holder of Notes that does not exchange that Holder's
Notes for New Notes will continue to hold the untendered Notes and will be
entitled to all the rights and limitations applicable thereto under the
Indenture, except to the extent that such rights or limitations, by their terms,
terminate or cease to have further effectiveness as a result of the Exchange
Offer.
 
     The Notes that are not exchanged for New Notes pursuant to the Exchange
Offer will remain restricted securities. Accordingly, such Notes may be resold
only (i) to the Company (upon redemption thereof or otherwise), (ii) pursuant to
an effective registration statement under the Securities Act, (iii) so long as
the Notes are eligible for resale pursuant to Rule 144A, to a qualified
institutional buyer within the meaning of Rule 144A under the Securities Act in
a transaction meeting the requirements of Rule 144A, (iv) outside the United
States to a foreign person pursuant to the exemption from the registration
requirements of the Securities Act provided by Regulation S thereunder, (v)
pursuant to an exemption from registration under the Securities Act provided by
Rule 144 thereunder (if available), or (vi) to an institutional accredited
investor in a transaction exempt from the registration requirements of the
Securities Act, in each case in accordance with any applicable securities laws
of any state of the United States. See "Risk Factors -- Failure to Exchange
Notes for New Notes."
 
OTHER
 
     Participation in the Exchange Offer is voluntary and Holders should
carefully consider whether to accept. Holders of the Notes are urged to consult
their financial and tax advisors in making their own decision on what action to
take.
 
     The Company may in the future seek to acquire untendered Notes in open
market or privately negotiated transactions, through subsequent exchange offers
or otherwise. The Company has no present plans to acquire any Notes that are not
tendered in the Exchange Offer or to file a registration statement to permit
resales of any untendered Notes.

                                THE TRANSACTIONS
 
THE ACQUISITION
 
     On December 8, 1997, Oshkosh entered into the Stock Purchase Agreement
pursuant to which, on February 26, 1998, it acquired all of the outstanding
capital stock of McNeilus and entered into related non-compete and ancillary
agreements for an aggregate acquisition price of $250.0 million. At November 30,
1997, McNeilus had unrestricted cash of $17.7 million ($20.2 million less an
estimated $2.5 million required for capital and surplus at McNeilus' captive
insurance subsidiary). The Stock Purchase Agreement required, among other
things, that the selling stockholders of McNeilus prepay certain notes and
purchase selected assets of McNeilus, which provided net proceeds to Oshkosh of
approximately $16.1 million. As a result, management estimates that the
effective cost to the Company in connection with the Acquisition was
approximately $216.2 million. Concurrently with the consummation of the
Acquisition, the Company consummated the Note Offering, established the Senior
Credit Facility, applied the net proceeds from the Note Offering and the Senior
Credit Facility to consummate the Acquisition, refinanced existing Oshkosh
indebtedness, paid fees and expenses and established the Lease Financing
Facility.
 
     The Stock Purchase Agreement contained customary representations and
warranties from McNeilus and the majority shareholders of McNeilus with respect
to McNeilus and the stock of McNeilus. The majority shareholders of McNeilus
have agreed to indemnify Oshkosh, its affiliates and McNeilus for any loss
resulting from: (i) any breach of any such representation or warranty; (ii) the
failure of McNeilus or the shareholders of McNeilus to comply with covenants
contained in the Stock Purchase Agreement; or (iii) any taxes imposed on
McNeilus or Oshkosh in connection with the disposition of certain assets of
McNeilus prior to closing of the Acquisition (the "Closing"); provided, however,
that such indemnity is limited to cover only losses in excess of $4.0 million in
the aggregate and less than $24.0 million in the aggregate. Such indemnification
obligations of the majority shareholders of McNeilus generally expire eighteen
months after the Closing. Oshkosh has agreed to indemnify the shareholders of
McNeilus for any loss resulting from: (i) any breach of any representation or
warranty made by Oshkosh pursuant to the Stock Purchase Agreement; (ii) the
failure of Oshkosh to comply with covenants contained in the Stock Purchase
Agreement; (iii) the operation of McNeilus after the Closing; or (iv) certain of
Oshkosh's actions in seeking financing for Oshkosh.
 
THE SENIOR CREDIT FACILITY
 
     The Senior Credit Facility is comprised of a multi-tranche Term Loan
Facility aggregating $225.0 million and a $100.0 million Revolving Credit
Facility entered into with Bank of America National Trust and Savings
Association ("Bank of America"), as agent and a lender, and certain other
financial institutions. The Senior Credit Facility is guaranteed by all of the
Company's domestic Restricted Subsidiaries (other than MFSI). See "Description
of Indebtedness -- Senior Credit Facility."
 
THE LEASE FINANCING FACILITY
 
     The Leasing Partner entered into a general partnership with BA Leasing &
Capital Corporation ("BALCAP"), an affiliate of the Initial Purchaser and Bank
of America, effective February 26, 1998. The Leasing Partnership offers lease
financing to customers of the Company and administers existing leases
contributed to the Leasing Partnership. Indebtedness under the Lease Financing
Facility is secured by the underlying leases and assets of, and is recourse to,
the Leasing Partnership; such indebtedness is off-balance sheet and non-recourse
to the Company. See "Description of Indebtedness -- Lease Financing Facility."

Oshkosh repaid in connection with the Transactions was comprised entirely of
borrowings under the Existing Bank Credit Agreement (as defined) (which bore
interest at a blended rate of approximately 7.78% at December 31, 1997 and which
would have matured beginning on September 30, 1999). See "The Transactions."

(1) On September 18, 1996, Oshkosh acquired for $156,926 in cash all of the
    issued and outstanding stock of Pierce, a manufacturer and marketer of fire
    trucks and other fire apparatus. The acquisition was accounted for using the
    purchase method of accounting and accordingly, the income statement data
    includes the operating results of Pierce since the date of acquisition.
 
(2) On June 2, 1995, Oshkosh sold certain assets associated with its motor home,
    bus and van chassis business. The consideration included cash of $23,815 and
    the assumption by the buyer of certain liabilities. The disposition of the
    chassis business has been accounted for as a discontinued operation and
    accordingly, the income statement data for 1995, 1994 and 1993 reflect the
    chassis business as a discontinued operation.
 
(3) EBITDA represents income (loss) from operations plus depreciation and
    amortization. EBITDA also includes the add-back of the non-cash write-off of
    certain Oshkosh investments of $4.1 million in the fiscal year ended
    September 30, 1996. Information concerning EBITDA has been included because
    management believes that EBITDA is generally accepted as providing useful
    information regarding a company's ability to service and/or incur debt.
    EBITDA should not be considered in isolation or as a substitute for net
    income, cash flows or other income or cash flow data prepared in accordance
    with generally accepted accounting principles or as a measure of a company's
    profitability or liquidity. The Company understands that, while EBITDA is
    frequently used by securities analysts in the evaluation of companies,
    EBITDA, as used herein, is not necessarily comparable to other similarly
    titled captions of other companies due to potential inconsistencies in the
    method of calculation. EBITDA is not intended as an alternative to cash flow
    from operating activities as a measure of liquidity, an alternative to net
    income as an indicator of operating performance or an alternative to any
    other measure of performance in conformity with generally accepted
    accounting principles. EBITDA margin percentage is calculated by dividing
    EBITDA by net sales.
 
(4) For purposes of the computation, the ratio of earnings to fixed charges has
    been calculated by dividing (i) income from continuing operations before
    income taxes plus fixed charges by (ii) fixed charges. Fixed charges are
    equal to interest expense plus the portion of the rent expense (one-third)
    estimated to represent interest expense. Earnings were inadequate to cover
    fixed charges in 1996 resulting in a deficiency of $1,982.
 
(5) Working capital represents total current assets less total current
    liabilities. Working capital at September 30, 1997, 1996, 1995, 1994 and
    1993 includes net current assets (liabilities) related to discontinued
    operations of ($1,536), ($1,975), $3,273, $15,882 and $12,084, respectively.
    Working capital at December 31, 1997 and 1996 includes net current
    (liabilities) related to discontinued operations of $(1,376) and $(1,801),
    respectively.

(1) In December 1997, McNeilus entered into agreements to sell its ready-mix,
    credit life insurance and travel operations. The dispositions of these
    businesses have been accounted for as discontinued operations and
    accordingly, the financial statement data as of and for fiscal years ended
    February 28, 1997, 1995, 1994, 1993 and February 29, 1996, and for the nine
    months periods ended November 30, 1997 and 1996, has been restated to
    reflect these businesses as discontinued operations.
 
(2) EBITDA represents income from operations plus depreciation and amortization.
    Information concerning EBITDA has been included because management believes
    that EBITDA is generally accepted as providing useful information regarding
    a company's ability to service and/or incur debt. EBITDA should not be
    considered in isolation or as a substitute for net income, cash flows or
    other income or cash flow data prepared in accordance with generally
    accepted accounting principles or as a measure of a company's profitability
    or liquidity. The Company understands that, while EBITDA, is frequently used
    by securities analysts in the evaluation of companies, EBITDA, as used
    herein, is not necessarily comparable to other similarly titled captions of
    other companies due to potential inconsistencies in the method of
    calculation. EBITDA is not intended as an alternative to cash flow from
    operating activities as a measure of liquidity, an alternative to net income
    as an indicator of operating performance or an alternative to any other
    measure of performance in conformity with generally accepted accounting
    principles. EBITDA margin percentage is calculated by dividing EBITDA by net
    sales.
 
(3) Working capital represents total current assets less total current
    liabilities. Working capital at February 28, 1997, 1995, 1994 and 1993, and
    February 29, 1996, and November 30, 1997 and 1996, includes no net assets
    (liabilities) related to discontinued operations.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
           CONSOLIDATED FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following contains Forward-Looking Statements. These statements are
subject to risks, uncertainties and other factors that could cause actual
results to differ materially from those described in or suggested by any such
statement. See "Disclosure Regarding Forward-Looking Statements."
 
HISTORICAL RESULTS OF OPERATIONS -- OSHKOSH
 
     The following discussion provides additional information regarding the
financial condition and results of operations of Oshkosh for the three-month
periods ended December 31, 1997 and 1996 and for each of the fiscal years ended
September 30, 1997, 1996 and 1995. The discussion should be read in conjunction
with "Selected Historical Consolidated Financial Data for Oshkosh" and Oshkosh's
historical consolidated financial statements and the notes thereto appearing
elsewhere in this Offering Memorandum.
 
     On December 8, 1997, Oshkosh entered into the Stock Purchase Agreement
pursuant to which, on February 26, 1998, it acquired all of the outstanding
capital stock of McNeilus and entered into related non-compete and ancillary
agreements for an aggregate acquisition price of $250.0 million. At November 30,
1997, McNeilus had unrestricted cash of $17.7 million ($20.2 million less an
estimated $2.5 million required capital and surplus at McNeilus' captive
insurance subsidiary). The Stock Purchase Agreement required, among other
things, that the selling stockholders of McNeilus prepay certain notes and
purchase selected assets of McNeilus, which provided net proceeds to Oshkosh of
approximately $16.1 million. As a result, management estimates that the
effective cost to the Company in connection with the Acquisition was
approximately $216.2 million. Concurrently with the consummation of the
Acquisition, the Company consummated the Note Offering, established the Senior
Credit Facility, applied the net proceeds from the Note Offering and the Senior
Credit Facility to consummate the Acquisition, refinanced existing Oshkosh
indebtedness, paid fees and expenses and established the Lease Financing
Facility. The Acquisition has been recorded using the purchase method of
accounting and McNeilus is being operated as a subsidiary of Oshkosh.
Accordingly, the discussion and analysis of historical periods does not reflect
the significant impact the Acquisition has had and will have on Oshkosh. See
"The Transactions," "Business -- The Acquisition" and "Unaudited Pro Forma
Condensed Consolidated Financial Statements."
 
Three Months Ended December 31, 1997 Compared to Three Months Ended December 31,
1996
 
     Oshkosh reported net income of $3.1 million, or $0.38 per share, on sales
of $151.8 million for the first quarter of fiscal 1998, compared to net income
of $1.6 million, or $0.19 per share, on sales of $150.3 million for the first
quarter of fiscal 1997.
 
     Sales of commercial products decreased slightly in the first quarter of
fiscal 1998 compared to the first quarter of fiscal 1997 while sales of defense
products increased slightly. Commercial sales in the first quarter of fiscal
1998 decreased $2.7 million or 3.3% from the first quarter of fiscal 1997 to
$80.5 million. A $5.8 million increase in sales of fire trucks and other fire
apparatus was more than offset by an $8.6 million decrease in sales of refuse
vehicles and the elimination of sales of commercial van trailers as Oshkosh
substantially exited this line of business. Sales of defense products totaled
$71.3 million in the first quarter of fiscal 1998, an increase of $4.2 million
or 6.3% as compared to the first quarter of fiscal 1997. The increase in defense
sales principally results from sales of LVS vehicles to the U.S. government.
Management does not expect the increase in defense product sales to continue
through the remainder of fiscal 1998.
 
     Gross income in the first quarter of fiscal 1998 totaled $22.3 million or
14.7% of sales compared to $19.6 million or 13.0% in the first quarter of fiscal
1997. Fiscal 1997 first quarter margins were adversely affected by increased
warranty and other costs related to refuse vehicle sales.
 
     Operating expenses totaled $14.9 million or 9.8% of sales in the first
quarter of fiscal 1998 compared to $13.2 million or 8.7% of sales in the first
quarter of fiscal 1997. The increase in operating expenses in the first quarter
of fiscal 1998 relates principally to increased operating expenses of Pierce of
$0.8 million associated with its growth in fire apparatus sales with the
remainder related to increases at Oshkosh's other operating units.
                                       38
<PAGE>   42
 
     Interest expense decreased to $2.5 million in the first quarter of fiscal
1998 compared to $3.6 million in the first quarter of fiscal 1997 due to
accelerated payments against the term loan used to finance the acquisition of
Pierce.
 
     The effective income tax rate for combined federal and state income taxes
for the first quarter of fiscal 1998 was 38.4% compared to 47.1% for the first
quarter of fiscal 1997. Fiscal 1998 benefitted from the reversal of $0.3 million
of income tax provisions recognized in earlier periods.
 
Additional Acquisition
 
     In addition to the Acquisition, on December 19, 1997, Oshkosh through its
wholly-owned subsidiary, Pierce, acquired certain inventory, machinery and
equipment, and intangible assets of Nova Quintech, a manufacturer of aerial
ladders, with available cash of $3.5 million.
 
Fiscal Year Ended September 30, 1997 Compared to Fiscal Year Ended September 30,
1996
 
     Oshkosh reported net income of $10.0 million, or $1.18 per share, on sales
of $683.2 million for the year ended September 30, 1997, compared to a net loss
of $3.1 million, or $0.35 per share, on sales of $413.5 million for the year
ended September 30, 1996. The fiscal 1997 results include a full year of sales
and earnings of Pierce, a leading manufacturer and marketer of fire trucks and
other fire apparatus in the U.S., which was acquired on September 18, 1996 (see
"-- Acquisitions"). The fiscal 1996 results were adversely affected by after-tax
charges of $11.3 million, including $3.2 million related to a defense
subcontract to Steeltech Manufacturing, Inc. ("Steeltech"), $3.5 million
associated with Oshkosh's Mexican bus affiliates, and warranty and other related
costs of $4.6 million. In fiscal 1996, Oshkosh also recognized after-tax
benefits of $2.0 million on the reversal of income tax provisions and related
accrued interest.
 
     Sales of both commercial and defense products increased in fiscal 1997
compared to fiscal 1996. Commercial sales in fiscal 1997 were $394.6 million, an
increase of $232.6 million, or 143.6% from 1996, principally due to inclusion of
a full year of Pierce sales in fiscal 1997. Commercial export sales totaled
$20.7 million and $20.4 million, respectively, in fiscal 1997 and fiscal 1996.
Sales of defense products totaled $288.6 million in fiscal 1997, an increase of
$37.2 million, or 14.8% compared to fiscal 1996. The increase in defense sales
was primarily due to an increase in sales of ISO-Compatible Palletized Flatracks
("IPF"), which were produced by Steeltech (which increased from $8.7 million in
fiscal 1996 to $41.4 million in fiscal 1997). Defense export sales also
increased to $16.6 million in fiscal 1997 compared to $2.1 million in fiscal
1996.
 
     Gross income in fiscal 1997 totaled $88.8 million, or 13.0% of sales,
compared to $35.1 million, or 8.5% of sales, in fiscal 1996. The increase in
gross income in fiscal 1997 was principally due to increased sales volume as a
result of the acquisition of Pierce. In addition, fiscal 1996 gross income was
reduced by pre-tax charges of $5.1 million related to production delays and cost
overruns associated with the IPF subcontract to Steeltech and increased warranty
and other related costs of $5.5 million (pre-tax).
 
     Operating expenses totaled $60.1 million, or 8.8% of sales, in fiscal 1997
compared to $38.7 million, or 9.4% of sales, in fiscal 1996. The increase in
operating expenses in fiscal 1997 related principally to the operating expenses
of Pierce and amortization of goodwill and other intangible assets associated
with the acquisition of Pierce. Oshkosh recognized pre-tax charges of $3.2
million in fiscal 1996 to write off its investment in Steeltech and to write off
its remaining investments and advances associated with its Mexican bus
affiliates due to prolonged weakness in the Mexican economy and continuing high
losses and high leverage reported by the Mexican affiliates.
 
     Interest expense increased to $12.7 million in fiscal 1997 compared to $0.9
million in fiscal 1996 as a result of the financing for the Pierce acquisition
(see "-- Liquidity and Capital Resources").
 
     Miscellaneous expense was $0.3 million in fiscal 1997 compared to
miscellaneous income of $1.5 million in fiscal 1996. The miscellaneous income in
fiscal 1996 arose primarily from the reversal of accrued interest related to
income taxes.
 
                                       39
<PAGE>   43
 
     The provision for income taxes in fiscal 1997 was $6.5 million, or 39.4% of
pre-tax income, compared to a credit for income taxes of $1.7 million in fiscal
1996. Fiscal 1997 and fiscal 1996 benefitted from the reversal of $0.9 million
and $1.0 million, respectively, of income tax provisions recognized in earlier
periods. In addition, the effective income tax rate in fiscal 1997 was adversely
affected by non-deductible goodwill of $2.6 million arising from the Pierce
acquisition.
 
     The $2.9 million after-tax loss from discontinued operations ($4.7 million
pre-tax) in fiscal 1996 resulted from the write-off of receivables of $2.6
million (pre-tax) related to the company's Mexican bus affiliates and from a
$2.1 million pre-tax charge for additional warranty and other related costs with
respect to Oshkosh's former U.S. chassis business which was sold in June 1995.
 
Fiscal Year Ended September 30, 1996 Compared to Fiscal Year Ended September 30,
1995
 
     Oshkosh reported a net loss of $3.1 million, or $0.35 per share, on sales
of $413.5 million for the year ended September 30, 1996, compared to net income
of $9.2 million, or $1.04 per share, on sales of $438.6 million for the year
ended September 30, 1995. The fiscal 1996 results were adversely affected by
after-tax charges of $11.3 million, including $3.2 million related to Steeltech,
$3.5 million associated with the company's Mexican bus affiliates, and warranty
and other related costs of $4.6 million. Oshkosh also recognized after-tax
benefits of $2.0 million on the reversal of income tax provisions and related
accrued interest in fiscal 1996. During the third quarter of fiscal 1995,
Oshkosh sold its chassis manufacturing business in the U.S. and its interest in
a joint venture in Mexico producing chassis for the Mexican market to
Freightliner Corporation ("Freightliner"). The activities of these businesses
are reported as discontinued operations and resulted in a charge to income in
fiscal 1995. In fiscal 1996, further after-tax charges of $1.3 million were
reported with respect to warranty and other related costs of the discontinued
operations. The results of Pierce from the date of acquisition to September 30,
1996, which were not material, have been included in the consolidated results of
Oshkosh.
 
     Sales of both commercial and defense products declined in fiscal 1996
compared to fiscal 1995. Commercial sales in fiscal 1996 decreased $14.8
million, or 8.4%, from fiscal 1995 to $162.0 million, primarily due to a decline
in sales of commercial van trailers of $31.7 million as Oshkosh substantially
exited this line of business. Sales of all other commercial product lines
increased in fiscal 1996. Commercial export sales totaled $20.4 million and
$17.5 million, respectively, in fiscal 1996 and fiscal 1995. Sales of defense
products totaled $251.5 million in fiscal 1996, a decrease of $10.3 million, or
3.9%, compared to fiscal 1995. The decrease in defense sales was a result of
delays in production of IPFs. Defense export sales were $2.1 million in fiscal
1996 compared to $1.6 million in fiscal 1995.
 
     Gross income in fiscal 1996 totaled $35.1 million, or 8.5% of sales,
compared to $54.0 million, or 12.3% of sales, in fiscal 1995. Fiscal 1996
margins were reduced by pre-tax charges of $5.1 million ($3.1 million in the
third quarter and $2.0 million in the fourth quarter) related to production
delays and cost overruns associated with a subcontract to Steeltech (see below),
increased warranty and other related costs of $5.5 million (pre-tax) of which
$2.1 million was recorded in the fourth quarter, and lower volume.
 
     Oshkosh subcontracted production under an $85 million IPF contract for the
U.S. Army to Steeltech, a minority-owned firm, pursuant to Department of Defense
regulations under the IPF contract. Due to financial difficulties encountered by
Steeltech, Oshkosh advanced working capital requirements to Steeltech in fiscal
1995 and 1996. As a result of delays in the start-up of full-scale production
under the IPF contract, Oshkosh wrote off advances of $3.1 million and its
investment in Steeltech of $.2 million in the third quarter of fiscal 1996 based
on projections of Steeltech's cash flows through completion of the IPF
subcontract.
 
     At June 30, 1996, Oshkosh believed that it was not necessary to write-off
its 50% interest in a joint venture that leased equipment to Steeltech nor
provide for its guarantee of the joint venture's debt, because Steeltech was
current with respect to its lease payments, and Oshkosh believed the equipment
could be sold at a value which would permit Oshkosh to recover its investment in
the joint venture. However, by September 30, 1996, Oshkosh concluded that
Steeltech would not likely achieve and sustain adequate cash flow to satisfy the
lease payments. Additionally, after further investigation, Oshkosh determined
that the equipment could not likely be sold at a value adequate to recover
Oshkosh's investment and satisfy the joint venture's
                                       40
<PAGE>   44
 
debt. Accordingly, Oshkosh wrote-off its investment in the joint venture and
accrued its guarantee at September 30, 1996 in an aggregate amount of $2.0
million.
 
     Operating expenses totaled $38.7 million, or 9.4% of sales, in fiscal 1996
compared to $34.7 million, or 7.9% of sales, in fiscal 1995. The company
recognized pre-tax charges of $3.2 million in fiscal 1996 to write off its
investment in Steeltech of $.2 million (see above) and to write off its
remaining investments and advances associated with its Mexican bus affiliates of
$3.0 million.
 
     Miscellaneous income increased to $1.5 million in fiscal 1996 compared to
miscellaneous expense of $0.5 million in fiscal 1995 as a result of the reversal
of accrued interest related to income taxes in fiscal 1996.
 
     The credit for income taxes totaled $1.7 million in fiscal 1996, benefiting
from the reversal of $1.0 million in income tax provisions recognized in earlier
periods, compared to a provision for income taxes of $7.3 million in fiscal
1995.
 
     The $2.9 million after-tax loss from discontinued operations ($4.7 million
pre-tax) in fiscal 1996 resulted from the write-off of receivables of $2.6
million (pre-tax) related to Oshkosh's Mexican bus affiliates and from a $2.1
million pre-tax charge for additional warranty and other related costs with
respect to Oshkosh's former U.S. chassis business which was sold in June 1995.
The $2.4 million after-tax loss from discontinued operations in fiscal 1995
reflects losses on the sale of Oshkosh's former U.S. chassis business and from
the sale of an interest in a former Mexican bus affiliate.
 
Acquisitions
 
     On September 18, 1996, Oshkosh acquired for cash all of the issued and
outstanding stock of Pierce, a leading manufacturer and marketer of fire trucks
and other fire apparatus in the U.S. The acquisition price of $156.9 million,
including acquisition costs and net of cash acquired, was financed from
borrowings under a bank credit facility. On November 9, 1995, Oshkosh through
its wholly-owned subsidiary, Summit Performance Systems, Inc., acquired the
inventory, land, buildings, machinery and equipment, and technology of Friesz
Manufacturing Company ("Friesz"), a manufacturer of concrete mixer systems and
related aftermarket replacement parts, from available cash for $3.9 million.
 
HISTORICAL RESULTS OF OPERATIONS -- MCNEILUS
 
     The following discussion provides additional information regarding the
results of operations of McNeilus for the nine-month periods ended November 30,
1997 and 1996 and for each of the fiscal years ended February 28, 1997, February
29, 1996 and February 28, 1995. The discussion should be read in conjunction
with "Selected Historical Consolidated Financial Data for McNeilus" and
McNeilus' historical consolidated financial statements and the notes thereto
appearing elsewhere in this Offering Memorandum.
 
     McNeilus sells concrete mixers mounted on truck chassis ("mixers") and
concrete mixers only ("mixer only"). McNeilus also sells refuse packer units
mounted on truck chassis ("packers") and packer units only ("packer only").
McNeilus' product lines also include ready-mix concrete mixer plants, as well as
replacement parts for all of McNeilus' products. McNeilus sells its products to
third parties and its lease financing subsidiary, MFSI.
 
     On December 8, 1997, the shareholders of McNeilus executed a definitive
agreement pursuant to which, on February 26, 1998, they sold all of the
outstanding capital stock of McNeilus to Oshkosh. The Stock Purchase Agreement
provided for the sale of certain of McNeilus' operating subsidiaries prior to
the consummation of the transaction with Oshkosh. As a result, McNeilus has
accounted for the subsidiaries being sold as discontinued operations and,
accordingly, prior period financial statements of McNeilus have been
reclassified to reflect the discontinuation of these operations. Other than this
reclassification, the discussion and analysis of historical periods does not
reflect the significant impact the Acquisition is expected to have on McNeilus.
See "Unaudited Pro Forma Condensed Consolidated Financial Statements."

Nine Months Ended November 30, 1997 Compared to Nine Months Ended November 30,
1996
 
     McNeilus reported net income of $13.5 million for the nine months ended
November 30, 1997 compared to net income of $11.6 million for the nine month
period ended November 30, 1996.
 
     Net sales for the nine months ended November 30, 1997 increased by $13.6
million or 5.8% over the prior year period to $246.8 million. Total unit volume
was comparable between periods, and the impact on net sales from significant
increases in packer only volume and increases in mixer and packer unit volumes
was offset by decreases in mixer only sales.
 
     Gross profit for the nine months ended November 30, 1997 totaled $43.1
million or 17.5% of net sales compared to $41.3 million or 17.7% of net sales
for the nine months ended November 30, 1996. The gross margin decrease was
principally as a result of the sale of a relatively lower proportion of higher
margin mixer only sales.
 
     Net interest income from leasing activities for the nine months ended
November 30, 1997 remained level at $1.9 million as compared to the prior
period.
 
     Selling and general and administrative expenses for the nine months ended
November 30, 1997 increased to $25.8 million or 10.5% of net sales compared to
$24.9 million or 10.7% of net sales for the nine months ended November 30, 1996,
generally reflecting the higher sales volume.
 
     Net other income increased to $1.2 million for the nine months ended
November 30, 1997 from $(0.2) million for the nine months ended November 30,
1996, primarily because interest expense decreased due to lower average
borrowings outstanding.
 
Fiscal Year Ended February 28, 1997 Compared to Fiscal Year Ended February 29,
1996
 
     McNeilus reported net income of $18.1 million in fiscal 1997 compared to
net income of $15.8 million in fiscal 1996.
 
     Net sales in fiscal 1997 decreased $18.4 million or 5.5% from fiscal 1996
to $313.0 million. The decrease resulted primarily from a substantial decrease
in packer and packer only sales as certain of McNeilus' largest commercial
customers curtailed capital spending. Mixer and mixer only sales in the
aggregate decreased 2.6% due to a shift in unit volume from mixer sales, which
include the price of the truck chassis, to mixer only sales, which are sold
without the truck chassis.
 
     Gross profit for fiscal 1997 totaled $55.8 million or 17.8% of net sales
compared to $49.6 million or 15.0% of net sales for fiscal 1996. Gross profit
increased due to the relatively higher proportion of mixer and mixer only sales,
which have higher overall margins compared to packer and packer only sales.
Improvements in manufacturing efficiencies and lower warranty expense also
helped improve gross profit.
 
     Net interest income from leasing activities in fiscal 1997 increased $0.3
million or 14.2% from fiscal 1996 to $2.6 million, generally reflecting higher
leasing volume.
 
     Selling and general and administrative expenses for fiscal 1997 increased
to $29.1 million or 9.3% of net sales compared to $27.5 million or 8.3% of net
sales for fiscal 1996, primarily due to increased advertising and bonuses.
 
     Net other income (expense) for fiscal 1997 decreased to $(0.5) million from
$0.7 million in fiscal 1996 because interest expense increased due to higher
average borrowings.
 
Fiscal Year Ended February 29, 1996 Compared to Fiscal Year Ended February 28,
1995
 
     McNeilus reported net income of $15.8 million in fiscal 1996 compared to
net income of $10.9 million in fiscal 1995.
 
     Net sales in fiscal 1996 increased $25.7 million or 8.4% from fiscal 1995
to $331.4 million. Mixer and mixer only sales were down slightly, while packer
and packer only sales were up substantially in fiscal 1996 compared to fiscal
1995. The increase in packer and packer only sales was primarily due to the
continued
                                       42
<PAGE>   46
 
expansion of the McNeilus packer product line which permitted increased sales to
large commercial customers.
 
     Gross profit for fiscal 1996 totaled $49.6 million or 15.0% of net sales
compared to $46.3 million or 15.1% of net sales for fiscal 1995. Gross profit
increased primarily as a result of higher sales volume, as gross margin
decreased slightly because of the shift in mix toward lower margin packer
product sales.
 
     Net interest income from leasing activities in fiscal 1996 increased $0.2
million or 8.4% from fiscal 1995 to $2.3 million, generally reflecting higher
leasing volume.
 
     Selling and general and administrative expenses for fiscal 1996 decreased
to $27.5 million or 8.3% of net sales compared to $29.3 million or 9.5% of net
sales for fiscal 1995, principally due to a decrease in charitable contribution
expense.
 
     Net other income for fiscal 1996 increased $0.8 million from fiscal 1995 to
$0.7 million primarily as a result of increased interest income.
 
FINANCIAL CONDITION
 
Three Months Ended December 31, 1997
 
     During the three months ended December 31, 1997, cash decreased $23.0
million. Cash of $23.0 million and cash provided from operating activities of
$16.8 million was used primarily to fund $32.2 million of long-term debt
repayments, the acquisition of Nova Quintech for $3.5 million, capital additions
of $1.7 million and dividends of $1.0 million.
 
Three Months Ended December 31, 1996
 
     During the three months ended December 31, 1996, cash increased $4.7
million. Cash provided from operations of $25.1 million exceeded cash
requirements for the repayment of long-term debt of $17.9 million, capital
additions of $1.3 million and dividends of $1.1 million.
 
Year Ended September 30, 1997
 
     During fiscal 1997, cash increased $23.1 million. Cash provided from
operating activities of $65.8 million was used primarily to fund $6.3 million of
capital additions, $1.7 million of payments related to discontinued operations,
$22.9 million of long-term debt payments, $6.5 million of purchases of common
stock and common stock warrants (net of stock option exercise proceeds) and $4.2
million of dividends.
 
Year Ended September 30, 1996
 
     During fiscal 1996, cash decreased $29.6 million. The acquisitions of
Pierce and Friesz for $160.8 million, cash used for operating activities of
$16.2 million, capital additions of $5.4 million, stock repurchases of $5.4
million and dividends of $4.4 million were funded principally from long-term
borrowings of $157.9 million, from available cash and from cash provided from
discontinued operations of $4.7 million. Cash was used for operating activities
in fiscal 1996 due to higher working capital requirements associated with sales
in the fourth quarter of fiscal 1996 and first quarter of fiscal 1997.
 
LIQUIDITY AND CAPITAL RESOURCES
 
Pro Forma
 
     Assuming consummation of the Transactions as of December 31, 1997, the
Company would have had pro forma Indebtedness of approximately $366.3 million
(including the Notes, but excluding additional borrowings available under the
revolving credit portion of the Senior Credit Facility). At the Closing, the
following amounts were drawn under the Senior Credit Facility: (i) $100.0
million on Term Loan A, which matures in six years; (ii) $62.5 million on Term
Loan B, which matures in seven years; (iii) $62.5 million on Term Loan C, which
matures in eight years; and (iv) on a pro forma basis at December 31, 1997,
approximately $13.0 million on the $100.0 million Revolving Credit Facility,
which matures in six years. The undrawn amount under the Revolving Credit
Facility is available for working capital and general corporate purposes,
including the issuance of letters of credit, which were approximately $8
million. After giving effect to the Transactions, the Company had approximately
$79 million of availability under the terms of the Revolving
                                       43
<PAGE>   47
 
Credit Facility on a pro forma basis. The Company's primary cash requirements
include working capital, interest and principal payments on indebtedness,
capital expenditures, dividends and potentially future acquisitions. The primary
sources of cash are cash flow from operations and borrowings under the Senior
Credit Facility. Based upon current and anticipated future operations, the
Company believes that capital resources will be adequate to meet future working
capital, debt service and other capital requirements. There can be no assurance,
however, that the Company's business will generate cash flow that, together with
the other sources of capital, will enable the Company to meet those
requirements.
 
     The Company's cash flow from operations has, and will likely continue to,
fluctuate significantly from period to period as the Company uses working
capital when producing orders and generates working capital when shipping those
orders. For example, the Company's use ($16.2 million) of cash in operations in
1996 and generation of $65.8 million in cash in 1997 resulted in significant
part from a substantial increase in inventories in 1996 and a corresponding
decrease in inventories in 1997, as certain large orders produced during 1996
were shipped during the first quarter of fiscal 1997. Similarly, if received, an
award of the MTTR or any other major DoD contract would likely entail increases
in the Company's working capital needs as it uses working capital to produce
vehicles or other equipment for shipment.
 
     The Leasing Partner entered into the Leasing Partnership effective February
26, 1998. The Leasing Partnership provides capital lease financing to customers
of the Company. MFSI had historically provided lease financing to customers of
McNeilus and, at the Closing, assigned its lease portfolio to the Leasing
Partner, which contributed the portfolio to the Leasing Partnership. Under the
terms of the Lease Partnership agreement, the Leasing Partner may be required to
make future equity contributions to the Lease Partnership based upon its pro
rata ownership interest and growth of the Leasing Partnership.
 
     The Senior Credit Facility and the Indenture, and other instruments of the
Company may, pose various restrictions and covenants on the Company that could
potentially limit the Company's ability to respond to market conditions, to
provide for unanticipated capital investments, to raise additional debt or
equity capital or to take advantage of business opportunities. See "Description
of Indebtedness -- Senior Credit Facility" and "Description of the New Notes --
Certain Covenants."
 
     The Senior Credit Facility accrues interest at variable rates. The Company
presently has no plans to enter into interest rate swap arrangements to limit
its exposure to future increases in interest rates.
 
     The Company's capital expenditures for fiscal years 1998 through 2000 are
expected to be approximately $12.0 to $15.0 million annually.
 
     The Company expects to continue to pay regular quarterly dividends of
$.10875 per share of Class A Common Stock and $.125 per share for Common Stock,
although the Company's ability to do so may be limited by the covenants
concerning restricted payments in the Indenture and the Senior Credit Facility.
 
Historical
 
     On September 18, 1996, Oshkosh entered into a bank credit agreement (the
"Existing Bank Credit Agreement") to finance the acquisition of Pierce and to
refinance a previous revolving credit facility. The Existing Bank Credit
Agreement initially consisted of a $150 million term loan which required annual
principal payments of $15 million through fiscal 2002 and a final payment of $60
million on September 30, 2003, and a $50 million revolving credit facility for
working capital purposes which would have expired on September 30, 1999. Through
December 31, 1997, Oshkosh made the $15 million principal payments due in
September 1997 and 1998, and paid another $25 million which was prorated against
the principal payments required in fiscal 1999 through fiscal 2003. At December
31, 1997, Oshkosh had borrowings under the revolving credit facility of $7.8
million and $8.2 million of standby letters of credit which reduced available
capacity under the revolving credit facility to $34.0 million. The total of all
term loan and revolving credit facility borrowings, excluding letters of credit,
would have been required to be reduced to or below $145.0 million and $130.0
million for 60 consecutive days in fiscal 1998 and 1999, respectively.
 
     On May 2, 1997, Oshkosh and Freightliner formally terminated a strategic
alliance formed on June 2, 1995. Oshkosh repurchased from Freightliner 350,000
shares of its Common Stock and 1,250,000 warrants for the purchase of additional
shares of Common Stock for a total of $6.8 million. Oshkosh and Freightliner
will continue to supply each other with parts and components.

<PAGE>   48
 
STOCK BUYBACK
 
     In July 1995, Oshkosh's Board of Directors authorized the repurchase of up
to 1,000,000 shares of Common Stock. As of December 31, 1997, Oshkosh had
purchased 461,535 shares under this program at a cost of $6.6 million. The
Indenture and the Senior Credit Facility will contain covenants which will limit
such repurchases after the consummation of the Transactions.
 
YEAR 2000
 
     Certain of the Company's older computer programs were written using two
digits rather than four to define the applicable year. As a result, those
computer programs may misinterpret a date using "00" as the year 1900 rather
than the year 2000. This could cause a system failure, miscalculations or other
disruptions in the business.
 
     Oshkosh maintains two primary computer systems at its Oshkosh operations
and one at its Pierce operations. Oshkosh is planning to install upgrades to its
present computer systems at Oshkosh by December 31, 1998. At Pierce, Oshkosh has
commenced a project, with outside consultants, to install new hardware and
software by February 1, 1999, to replace an obsolete hardware and software
system. The total cost of these projects during fiscal 1998 and 1999 is
estimated at approximately $6.6 million which includes $6.3 million for the
purchase of new hardware and software that will be capitalized and $0.3 million
that will be expensed as incurred. Oshkosh believes that following the
completion of these projects, the year 2000 issue will not pose significant
disruptions to its business; however, if such projects are not completed on a
timely basis, the year 2000 could have a material impact on the operations of
Oshkosh.
 
     McNeilus has entered into an agreement with an outside consultant to
upgrade its present computer systems by August 1998. The total cost of this
upgrade, which is intended to, among other things, prevent any disruptions
related to year 2000 issues, is estimated at approximately $400,000 and will be
expensed. The Company believes that following the conclusion of this upgrade,
the year 2000 issue will not pose significant disruptions to McNeilus' business;
however, if such upgrades are not completed on a timely basis, the year 2000
could have a material impact on the operations of McNeilus.
 
NEW ACCOUNTING STANDARDS
 
     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive
Income." SFAS No. 130 establishes the standards for reporting and displaying
comprehensive income and its components (revenues, expenses, gains, and losses)
as part of a full set of financial statements. This statement requires that all
elements of comprehensive income be reported in a financial statement that is
displayed with the same prominence as other financial statements. The statement
is effective for fiscal years beginning after December 15, 1997. Since this
statement applies only to the presentation of comprehensive income, it will not
have any impact on the Company's results of operations, financial position or
cash flows.
 
     In June 1997, the Financial Accounting Standards Board also issued SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 establishes the standards for the manner in which public enterprises are
required to report financial and descriptive information about their operating
segments. The statement defines operating segments as components of an
enterprise for which separate financial information is available and evaluated
regularly as a means for assessing segment performance and allocating resources
to segments. A measure of profit or loss, total assets and other related
information are required to be disclosed for each operating segment. In
addition, this statement requires the annual disclosure of information
concerning revenues derived from the enterprise's products or services,
countries in which it earns revenue or holds assets, and major customers. The
statement is also effective for fiscal years beginning after December 15, 1997.
The adoption of SFAS No. 131 will not affect the Company's results of operations
or financial position, but will affect the disclosure of segment information.

                                    BUSINESS
 
THE COMPANY
 
     The Company is a leading designer, manufacturer and marketer of a broad
range of fire apparatus and specialty commercial and military trucks under the
"Oshkosh," "Pierce," "McNeilus" and "MTM" trademarks. The Company's custom and
commercial fire apparatus include pumpers, aerial and ladder trucks, tankers,
heavy-duty rescue vehicles, wildland rough terrain response vehicles and ARFF
vehicles. The Company's commercial truck lines include refuse truck bodies,
rear- and forward-discharge concrete mixers and snow removal vehicles. As the
leading manufacturer of severe-duty heavy tactical trucks for the DoD, the
Company manufactures vehicles that perform a variety of demanding tasks such as
hauling tanks, missile systems, ammunition, fuel and cargo for combat units. For
the twelve months ended December 31, 1997, on a pro forma basis, the Company
generated net sales of $1,011.3 million and EBITDA of $79.4 million.
 
     The Company's objective is to continue to enhance market positions by
providing innovative design, sophisticated engineering, efficient, low-cost
manufacturing, extensive distribution and superior customer service to its
commercial, municipal and military customers within its core markets.
 
COMPETITIVE STRENGTHS
 
     The following competitive strengths support the Company's business
strategy:
 
     Strong Market Positions. The Company has developed strong market positions
in each of its core businesses, which management attributes to the Company's
reputation for innovation, vehicle performance, reliability and customer
service. The Company has the leading share of the severe-duty heavy tactical
truck segment of the domestic defense truck market, and also believes it has a
leading share in: (i) custom and commercial fire apparatus, including pumpers,
aerial and ladder trucks, tankers, heavy duty rescue, wildland rough terrain
response vehicles and ARFF vehicles for the domestic fire apparatus market; (ii)
the domestic refuse truck body market; (iii) the domestic rear- and
forward-discharge concrete mixer markets; and (iv) the domestic airport snow
removal vehicle market. The Company intends to continue to strengthen its market
share by capitalizing on its strong reputation, introducing innovative products
and services and leveraging its extensive distribution capabilities.
 
     Extensive Distribution Capabilities. With the addition of the commercial
and municipal distribution capabilities of Pierce and McNeilus, the Company has
established an extensive domestic and international distribution system for
specialty trucks and truck bodies covering over 70 countries. In addition to its
network of dealers and distributors, the Company employs over 100 in-house sales
and service representatives. Management believes the Company's broad
distribution system has enabled the Company to: (i) maximize sales of new
products and technologies: (ii) become a benchmark for government customers in
establishing their bid specifications; (iii) provide customer service on a
national and international scale; and (iv) reduce distribution expenses through
significant economies of scale.
 
     Flexible and Efficient Manufacturing. The Company believes it has
competitive advantages over larger truck manufacturers in its specialty truck
markets due to its manufacturing flexibility and custom fabrication
capabilities. For example, the Company has successfully configured its defense
truck and fire apparatus manufacturing plants for the simultaneous manufacture
of many different types and models of vehicles on the same assembly line. In
addition, the Company believes it has a competitive advantage over smaller
competitors due to its: (i) manufacturing in relatively higher volumes; (ii)
purchasing power across its product lines; and (iii) investing in fixturing and
robotics to improve efficiency and reduce costs.
 
     Quality Products and Customer Service. Oshkosh, Pierce and McNeilus have
each developed strong brand recognition based on their commitments to meet the
stringent product quality and reliability requirements of their customers and
the specialty truck markets they serve. The Company's commitment to product
quality is exemplified by the ISO 9001 certification of Oshkosh. Pierce is
targeting achievement of ISO 9001 certification in 1998. The Company also
achieves high quality customer service through its
 
                                       46
<PAGE>   50
 
extensive service and parts support program, which is available to domestic
customers 365 days a year in all product lines throughout the Company's
distribution systems.
 
     Proprietary Components. The Company's advanced design and engineering
capabilities have contributed to the development of proprietary, severe-duty
components which enhance truck performance, reduce manufacturing costs and
strengthen customer relationships. These proprietary components include front
drive and steer axles, transfer cases, cabs, the ALL-STEER electronic all-wheel
steering system, central tire inflation, independent suspension, the Sky-Arm
articulating aerial ladder and the McNeilus Auto Reach Arm. Management believes
these proprietary components provide the Company a competitive advantage by
increasing its vehicles' durability, operating efficiency and vehicle
effectiveness. The integration of many of these components across various
certain product lines also reduces the Company's costs to manufacture its
products compared to manufacturers who simply assemble purchased components.
 
BUSINESS STRATEGY
 
     The Company is focused on increasing its net sales, profitability and cash
flow by capitalizing on its competitive strengths. Key elements of the Company's
business strategy include:
 
     Focusing on Specialized Truck Markets. The Company plans to continue its
focus on those specialized truck and truck body markets where it has strong
market positions and where the Company can leverage synergies in purchasing,
manufacturing, technology and distribution. The Company's objective is to
achieve and maintain market leadership through internal growth and strategic
acquisitions. Management believes the higher sales volumes associated with
market leadership would allow the Company to continue to enhance productivity in
manufacturing operations, fund innovative product development and invest in
further expansion.
 
     Expanding Distribution and International Sales. The Company plans to add
new distribution capabilities for the municipal segment of the refuse truck body
market and in targeted geographic areas in the domestic fire apparatus market.
The Company intends to increase international sales beyond the $58.9 million pro
forma volume achieved in the twelve months ended December 31, 1997 by
introducing McNeilus refuse truck bodies, rear-discharge concrete mixers and
ready-mix batch plants to international markets and by continuing the expansion
of Pierce's international customer base through the Company's expanding
international distribution capabilities.
 
     Reducing Costs While Maintaining Quality. The Company actively benchmarks
its competitors' costs and best industry practices, and continuously seeks to
implement process improvements to increase cash flow and improve profitability.
With each of its acquisitions, the Company has established cost reduction
targets. At Pierce, the Company exceeded its first-year cost reduction target of
$3.4 million in fiscal 1997 as a result of consolidating facilities,
reengineering the manufacturing process and leveraging increased purchasing
power. The Company is planning for additional cost savings at Pierce in fiscal
1998. The Company intends to improve efficiencies after the acquisition of
McNeilus by taking advantage of the Company's greater purchasing power and by
developing additional manufacturing synergies across product lines.
 
     Introducing New Products. The Company has increased its emphasis on new
product development in recent years, and seeks to expand sales by introducing
new or improved products in its core markets, either through internal
development or strategic acquisition. For example, in December 1997, the Company
purchased the aerial fire apparatus product line of Nova Quintech, a division of
Nova Bus Corporation. This acquisition broadened Pierce's aerial product line
and is expected to provide Pierce with three new products in the first half of
calendar 1998.
 
     Diversifying DoD Contracts. The Company is seeking to diversify its
business with the DoD beyond its traditional contracts relating to the
manufacture of severe-duty heavy tactical trucks. Management believes the
Company has a reputation within the DoD for advanced engineering, quality
manufacturing and vehicle performance that will assist the Company in obtaining
contracts to provide other types of vehicles to the DoD. For example, the
Company was one of two manufacturers selected to participate in a DoD program to
produce upgraded medium-duty prototype vehicles for the MTTR program. The
Company expects the testing and
 
                                       47
<PAGE>   51
 
validation phase for the MTTR program to conclude in the first half of 1998 and
the initial production contract to be awarded to the Company or the competing
bidder in the fourth quarter of 1998. The Company is also one of two
manufacturers competing for the DoD's FMTV contract. The Company and the other
participating manufacturer are currently preparing prototype FMTV trucks for
testing by the DoD.
 
     Increasing Aftermarket Sales and Service. The Company is focused on
increasing its aftermarket sales and service revenues. In the fire apparatus and
commercial truck markets, the Company has expanded and plans to continue to
expand its refurbishment facilities and parts distribution capabilities. In the
defense truck market, the Company plans to continue to pursue parts and
maintenance contracts for upgrading and reconditioning trucks at both domestic
and international U.S. military bases.
 
     Pursuing Strategic Acquisitions. Following the integration of McNeilus, the
Company intends to selectively pursue additional strategic acquisitions, both
domestically and internationally, in order to enhance its product line and
expand its international presence in specialized truck markets. The Company
intends to focus its acquisition strategy in specialty truck and truck body
markets where it can enhance its strong market positions and achieve significant
acquisition synergies.
 
THE ACQUISITION
 
     On December 8, 1997, Oshkosh entered into the Stock Purchase Agreement
pursuant to which, on February 26, 1998, it acquired all of the outstanding
capital stock of McNeilus and entered into related non-compete and ancillary
agreements for an aggregate acquisition price of $250.0 million. At November 30,
1997, McNeilus had unrestricted cash of $17.7 million ($20.2 million less an
estimated $2.5 million required for capital and surplus at McNeilus' captive
insurance subsidiary). The Stock Purchase Agreement required, among other
things, that the selling stockholders of McNeilus prepay certain notes and
purchase selected assets of McNeilus, which provided net proceeds to Oshkosh of
approximately $16.1 million. As a result, management estimates that the
effective cost to the Company in connection with the Acquisition was
approximately $216.2 million. Concurrently with the consummation of the
Acquisition, the Company consummated the Note Offering, established the Senior
Credit Facility, applied the net proceeds from the Note Offering and the Senior
Credit Facility to consummate the Acquisition, refinanced existing Oshkosh
indebtedness, paid fees and expenses and established the Lease Financing
Facility.
 
PRODUCTS AND MARKETS
 
     Following the Pierce and McNeilus acquisitions, the Company is focused on
the following core specialty truck and truck body markets:
 
     Fire Apparatus. The Company, through Pierce, is among the leading domestic
manufacturers of custom and commercial fire apparatus. The Company primarily
serves domestic governmental markets, but also sells fire apparatus to airports,
universities and large industrial companies. In addition, the Company sells fire
apparatus in international markets. Pierce's history of research and development
in consultation with firefighters has resulted in a broad product line that
features a wide range of innovative, high-quality custom and commercial
firefighting equipment with advanced fire suppression capabilities. The
Company's engineering expertise also allows it to design its vehicles to meet
stringent government regulations for safety and effectiveness.
 
     Refuse Truck Bodies. Management believes the Company, through McNeilus, is
a leading domestic manufacturer of refuse truck bodies for the waste services
industry. The Company manufactures a wide range of automated rear, front, side
and top loading refuse truck bodies, which the Company mounts on commercial
chassis. The Company sells its refuse vehicles primarily to commercial waste
management companies. Management believes the Company's refuse vehicles have a
reputation for efficient, cost-effective, dependable operation that supports the
Company's continued expansion into municipal and international markets.
 
     Concrete Mixers and Snow Removal Vehicles. Management believes the Company
is a leading domestic manufacturer of rear- and forward-discharge concrete
mixers. The Company sells rear- and forward-discharge concrete mixers and
portable concrete mixer plants to construction companies throughout the United
States

and internationally. Management believes the Company is one of the only domestic
concrete mixer manufacturers that markets both rear- and forward-discharge
concrete mixers.
 
     The Company is also among the leading domestic manufacturers of snow
removal vehicles for airports. The Company's specially designed airport snow
removal vehicles can cast up to 4,000 tons of snow per hour and are used by some
of the largest airports in the United States, such as Denver International
Airport, LaGuardia International Airport, Minneapolis-St. Paul International
Airport and O'Hare International Airport. Management believes the reliability of
the Company's high performance snow removal vehicles contribute to its strong
market position.
 
     Defense Trucks. The Company has sold products to the DoD for over 70 years
and is the leading manufacturer of a broad line of severe-duty heavy tactical
trucks for the DoD. The Company's proprietary military all-wheel drive product
line includes: (i) the PLS, a highly mobile self-contained truck and trailer
system that loads and unloads a wide range of cargo in a short period of time;
(ii) the HEMTT, a cross-country cargo and supply carrier that, among other
tasks, is used for direct rearming of the Multiple Launch Rocket System,
transport of Patriot erector/launchers, resupply of field artillery ammunition
and refueling of tanks, trucks and helicopters in forward areas; (iii) the HET,
the primary hauler of the M1A1 main battle tank and also a hauler of other
tanks, fighting and recovery vehicles, self-propelled howitzers and construction
equipment; and (iv) the LVS, a highly mobile cargo carrier with a maximum
payload capacity of 20 tons. The Company also exports its severe-duty heavy
tactical trucks to approved foreign customers.
 
     The Company has developed a strong relationship with the DoD that has
resulted in the Company operating under "family contracts" with the DoD for the
PLS, HEMTT, HET and LVS and for DoD vehicle parts. Under the vehicle family
contracts, the DoD orders a specified range of volume of trucks at fixed prices,
which allows the Company to predict and plan its products and delivery schedules
for vehicles. These family contracts were established in 1996 and 1997 and
expire in fiscal years 1999 and 2000.

SALES AND DISTRIBUTION
 
     The Company believes it differentiates itself from many of its larger
competitors by tailoring its distribution to the needs of its specialized truck
markets and from its smaller competitors with its national and global sales and
service capabilities. Distribution personnel use demonstration trucks to show
customers how to properly use the Company's trucks and truck bodies, compared to
the showroom sales approach of the typical dealers of large truck manufacturers.
The Company backs all products by same-day parts shipment, and its service
technicians are available in person or by telephone to domestic customers 365
days a year. The Company believes that its dedication to keeping its trucks
in-service in demanding conditions worldwide has contributed to customer
loyalty.
 
     The Company provides its salespeople, representatives and distributors with
product and sales training on the operation and specifications of its products.
The Company's engineers, along with its product managers, develop operating
manuals and provide field support at truck delivery for certain markets.
 
     Distributors, where used, enter into agreements with the Company that allow
for termination by either party generally upon 90 days' notice. Distributors are
not permitted to market and sell competitive products.
 
     Fire Apparatus Market. The Company believes that the geographical breadth,
size and quality of its fire apparatus sales and service organization are
competitive advantages in a market characterized by a few large manufacturers
and numerous small, regional competitors. Pierce's fire apparatus are sold
through 38 sales and service organizations with more than 260 sales
representatives nationwide, which combine broad geographical reach with
frequency of contact with fire departments and municipal government officials.
Management believes that frequency of contact and local presence are important
to cultivate major, and typically infrequent, purchases involving the city or
town council and fire department, purchasing, finance, and mayoral offices,
among others, that may participate in a fire truck bid and selection. After the
sale, Pierce's nationwide local parts and service capability is available to
help municipalities maintain peak readiness for this vital municipal service.
 
     Pierce primarily focused its sales efforts in rural and small suburban
domestic markets prior to its acquisition by Oshkosh. Due to its expertise and
long-standing relationships in numerous large urban markets, the Company has
extended Pierce's sales focus into several key metropolitan areas. As a direct
result of a targeted approach to major urban markets, Pierce was awarded the two
largest U.S. fire truck contracts in its history in fiscal 1997.
 
     Pierce substantially strengthened its competitive position overseas in
fiscal 1997. Pierce's worldwide distribution network was expanded to include 43
international representatives. This network has delivered several new orders
including the award in December 1997 of a $35 million contract for 130 custom
fire trucks for Saudi Arabia to be delivered from November 1998 through October
1999.
 
     The Company has invested in the development of sales tools for its
representatives which it believes creates a competitive advantage in the sale of
fire apparatus. For example, Pierce's Pride II PC-based sales tool can be used
by its sales representatives to develop the detail specifications, price the
base truck and options and draw the configured truck on the customer's premises.
The quote, if accepted, is directly interfaced into Pierce's sales order
systems.
 
     Refuse Truck Body, Concrete Mixer and Snow Removal Vehicle Markets. Oshkosh
maintains four distribution centers with 26 in-house sales and service
representatives in the U.S. to sell and service its forward- and rear-discharge
concrete mixers. All of the Oshkosh facilities provide full service, mounting
and parts distribution to customers in their geographic regions, while two also
have paint facilities. In addition, Oshkosh utilizes three independent
distributors in this market. Oshkosh also maintains 22 full sales and service
dealers focused on the sale of snow removal vehicles, principally to airports,
but also to municipalities, counties and other governmental entities.
 
     McNeilus operates eight distribution centers with 83 in-house sales and
service representatives in the U.S. to sell and service its refuse truck bodies,
rear-discharge concrete mixers and ready-mix batch plants. Six of such
distribution centers provide full service, mounting and parts distribution to
customers in their
 
                                       52
<PAGE>   56
 
geographic regions while the remainder are primarily sales offices with limited
parts and service capabilities. Five of the McNeilus distribution centers also
have paint facilities and provide significant additional paint and mounting
services during peak demand periods.
 
     With respect to McNeilus, the Company plans to:
 
     - Combine the McNeilus and Oshkosh distribution capabilities. Because there
      is little geographic overlap between the rear-discharge markets of
      McNeilus and the forward-discharge markets of Oshkosh, management
      presently intends to maintain all existing distribution centers of both
      companies. The Company believes that the combined network will represent
      one of the largest refuse truck body and concrete mixer distribution
      networks in the U.S.
 
     - Apply Oshkosh's and Pierce's sales and marketing expertise in municipal
      markets to increase sales of McNeilus refuse truck bodies to municipal
      customers. Virtually all McNeilus refuse truck body sales have been to
      commercial customers, which the Company believes represent a majority of
      the refuse truck body market. However, many municipalities purchase their
      own refuse trucks, and the Company believes that it is positioned to
      create an effective municipal distribution in the refuse truck body market
      by building upon its present base of municipal distributors.
 
     - Offer McNeilus refuse truck bodies, rear-discharge concrete mixers and
      ready-mix batch plants to Oshkosh's 43 international dealers for sales and
      service worldwide. McNeilus' international sales have historically been
      limited because McNeilus has focused on the domestic market. However,
      management believes that refuse body exports are a significant percentage
      of certain competitors' sales, and represents a meaningful opportunity for
      the Company. The Company believes that its international Oshkosh and
      Pierce dealers are capable of effectively selling and servicing the
      McNeilus product line and plans to use its experience at Pierce to develop
      sales of McNeilus products.
 
     Defense Truck Market. Substantially all domestic defense products are sold
direct to principal branches of the DoD. The Company maintains a liaison office
in Washington, D.C. to represent its interests with the Pentagon, Congress and
the Office of the President. The Company also sells and services defense
products to foreign governments directly through four Company-owned
international sales offices, through agents, consultants and representatives,
and through the United States FMS program. The DoD has begun to rely on industry
for support and sustainability of its vehicles which has opened up new
opportunities for maintenance, service and contract support to the U.S. Army and
U.S. Marine Corps.
 
     In addition to marketing its current truck offerings and competing for new
contracts in the medium- and light-duty segments, the Company actively works
with the Armed Services to develop new applications for its vehicles. For
example, the Company is:
 
     - Developing new applications for its PLS vehicle beyond its traditional
      ammunition transportation role. A contract for construction models has
      already been awarded, and several other models of the PLS are currently
      under evaluation.
 
     - Modifying its HEMTT vehicle for alternate uses. The Company has
      integrated a foam proportioning fire fighting package on a HEMTT for use
      by the U.S. military and other governmental agencies in the extinguishment
      of wildland fires. The HEMTT has also been modified to include a load
      handling system to meet lower payload requirements.
 
     - Upgrading existing products such as the HEMTT, PLS and HET in order to
      achieve better performance and new technology. As an example, the Company
      has separate development contracts for each product with the U.S. Army to
      develop a new HEMTT, HET and PLS with new engines, transmissions, transfer
      cases and numerous other components that increase reliability and
      performance at reduced costs.
 
COMPETITION
 
     The Company operates in highly competitive industries. The Company competes
in the fire apparatus and defense truck markets principally on the basis of
lowest qualified bid. To submit a qualified bid, the bidder

                                       53
<PAGE>   57
 
must demonstrate that the fire apparatus or defense truck meets stringent
specifications, and for most defense truck contracts, passes extensive testing.
In addition, decreases in the DoD budget have resulted in a reduction in the
number and size of contracts, which has intensified the competition for
remaining available contracts. The Company and its competitors continually
undertake substantial efforts in order to maintain existing levels of defense
business and to succeed in bid competitions for available contracts. In the
refuse truck body and concrete mixer markets, the Company also faces intense
competition on the basis of price, innovation, quality, service and product
performance capabilities. As the Company seeks to expand its sales of refuse
truck bodies to municipal customers, management believes the principal basis of
competition for such business will be lowest qualified bid.
 
     In all of the Company's markets, competitors include smaller, specialized
manufacturers as well as large, mass producers. The Company believes that, in
its specialized truck markets, it has been able to effectively compete against
large, mass producers due to its manufacturing flexibility and specialized
distribution systems. The Company believes that its competitive cost structure,
engineering expertise and global distribution systems have enabled it to
effectively compete with other specialized manufacturers.
 
     Pierce's principal competitors in the fire apparatus market include
Emergency One, Inc. (a subsidiary of Federal Signal Corporation), FWD
Corporation (a subsidiary of Corsta Corporation), Kovatch Mobile Equipment
Corp., and numerous small, regional manufacturers. Principal competitors of
McNeilus, in the refuse truck body market, include The Heil Company (a
subsidiary of Dover Corporation), Leach Company, McClain E-Z Pack, Inc. and
Pak-Mor Manufacturing Company. Principal competitors of McNeilus and Oshkosh in
concrete mixer markets include Advance Mixer, Inc., London Machinery, Inc., Mack
Trucks, Inc., Maxim Truck Company, Inc., Rexworks, Inc., and T.L. Smith Machine
Co., Inc. Oshkosh's principal competitors in snow removal markets include Monroe
Truck Equipment, Inc. and Stewart & Stevenson Services, Inc. Oshkosh's principal
competitors for DoD contracts include AM General Corporation and Stewart &
Stevenson Services, Inc. The Company also faces competition from its competitors
for acquisition opportunities.
 
     Several of the Company's competitors have greater financial, marketing,
manufacturing and distribution resources than the Company. There can be no
assurance that the Company's products will continue to compete successfully with
the products of competitors or that the Company will be able to retain its
customer base or to improve or maintain its profit margins on sales to its
customers, all of which could materially adversely affect the Company's
financial condition, results of operations and debt service capability.
 
CUSTOMERS AND BACKLOG
 
     Sales to the DoD comprised approximately 29% of the Company's pro forma net
sales for the twelve months ended December 31, 1997. No other single customer
accounted for more than 2% of the Company's pro forma sales for this period. A
substantial majority of the Company's net sales are derived from customer orders
prior to commencing production.
 
     The Company's pro forma backlog at December 31, 1997 was $438.3 million.
The backlog at December 31, 1997 includes $147.5 million related to DoD
contracts, $159.0 million related to fire apparatus and $131.8 million related
to other commercial products. Substantially all of the Company's backlog
pertains to fiscal 1998 business.
 
     The Company's historical backlog, excluding McNeilus, was $377.9 million at
December 31, 1997 compared to $398.2 million at December 31, 1996. The $20.3
million decrease in backlog from December 31, 1996 to December 31, 1997 is due
to a $77.4 million decrease related to DoD contracts, partially offset by
increases of $37.2 million related to fire apparatus and $19.9 million related
to other commercial products. Backlog information for McNeilus was unavailable
at December 31, 1996.
 
     Reported backlog excludes purchase options and announced orders for which
definitive contracts have not been executed. Additionally, backlog excludes
unfunded portions of DoD long-term family contracts. Backlog information and
comparisons thereof as of different dates may not be accurate indicators of
future sales or the ratio of the Company's future sales to the DoD versus its
sales to other customers.

GOVERNMENT CONTRACTS
 
     Approximately 29% of the Company's pro forma net sales for the twelve
months ended December 31, 1997 were made to the U.S. government under long-term
contracts and programs, substantially all of which were in the defense truck
market. Accordingly, a significant portion of the Company's sales are subject to
inherent risks, including uncertainty of economic conditions, changes in
government policies and requirements that may reflect rapidly changing military
and political developments and the availability of funds.
 
     The Company's sales into defense truck markets are substantially dependent
upon periodic awards of new contracts and the purchase of base vehicle
quantities and the exercise of options under existing contracts. The Company's
existing contracts with the DoD may be terminated at any time for the
convenience of the government. Upon such termination, the Company would
generally be entitled to reimbursement of its incurred costs and, in general, to
payment of a reasonable profit for work actually performed.
 
     In November 1996, the U.S. Army Tank Automotive and Armaments Command
awarded the Company and one other defense contractor $6.9 million prototype
contracts for Phase I competition of the MTTR program. The MTTR program was
initiated to update and modernize the 5-ton tactical vehicle fleet of the U.S.
Marine Corps and the U.S. Army. The goal of the U.S. Marine Corps portion of the
program is to remanufacture the current configuration to carry a much greater
payload with substantially increased cross-country mobility. The U.S. Army
portion of the program is designed to increase the useful life and decrease
operation and support costs of a portion of the U.S. Army's existing fleet.
Phase I covers the design, development, and production of five prototype test
vehicles for the U.S. Marine Corps and five additional prototype test vehicles
for the U.S. Army. Testing of the ten prototype test vehicles commenced August
1997 and will be concluded in April 1998. Phase II of the program is currently
expected to include the production of up to 11,500 U.S. Marine Corps and U.S.
Army units at a value that could exceed $1.0 billion over a period of years.
Competition for the Phase II production contract is intense between the two
Phase I contractors. Phase I testing along with the Phase II proposal will
determine the single supplier of any production contract awarded. No assurance
can be given that the DoD will award a Phase II Contract or that federal budgets
will provide future funding for a Phase II contract, as further discussed under
"Risk Factors -- Uncertainty Inherent in U.S. Government Contracts" and "--
Risks of Further Reductions or Changes in Government Expenditures."
 
     The U.S. Army has announced a competition to add a second supplier to build
FMTV trucks. Up to three contractors will build several trucks for testing by
the DoD pursuant to a request for proposal currently under development by the
DoD. The Company currently has received two existing vehicles for intense study
in preparation for the competition. Based on current plans announced by the DoD,
the winner of the competition would be awarded an initial production contract
for approximately 3,000 vehicles. Upon completion of this production contract
and the current supplier's present contract, the U.S. Army is expected to
conduct a competition between these two manufacturers for the production of
approximately 50,000 FMTV trucks. No assurance can be given that the DoD will
award the FMTV contract or that federal budgets will provide future funding for
the FMTV contract, as further discussed under "Risk Factors -- Uncertainty
Inherent in U.S. Government Contracts" and "-- Risks of Further Reductions or
Changes in Government Expenditures."
 
     Under firm fixed-price contracts with the government, the price paid to the
Company is generally not subject to adjustment to reflect the Company's actual
costs, except costs incurred as a result of contract changes ordered by the
government. The Company generally attempts to negotiate with the government the
amount of increased compensation to which the Company is entitled for
government-ordered changes which result in higher costs. In the event that the
Company is unable to negotiate a satisfactory agreement to provide such
increased compensation, the Company may file an appeal with the Armed Services
Board of Contract Appeals or the U.S. Claims Court. The Company has no such
appeals pending.
 
     The Company, as a U.S. government contractor, is subject to financial
audits and other reviews by the U.S. government of performance of, and the
accounting and general practices relating to, U.S. government contracts, and
like most large government contractors, the Company is audited and reviewed on a
continual
 
                                       55
<PAGE>   59
 
basis. Costs and prices under such contracts may be subject to adjustment based
upon the results of such audits and reviews. Additionally, such audits and
reviews can and have led to civil, criminal or administrative proceedings. Such
proceedings could involve claims by the government for fines, penalties,
compensatory and treble damages, restitution and/or forfeitures. Under
government regulations, a company or one or more of its subsidiaries can also be
suspended or debarred from government contracts, or lose its export privileges
based on the results of such proceedings. Additional information is included
under the caption "Risk Factors -- Uncertainty Inherent in U.S. Government
Contracts." The Company believes, based on all available information, that the
outcome of all such audits, reviews and proceedings will not have a material
adverse effect on its consolidated financial condition or results of operations.
 
SUPPLIERS
 
     The Company is highly dependent on its suppliers and subcontractors in
order to meet commitments to its customers, and many major components are
procured or subcontracted on a sole-source basis with a number of domestic and
foreign companies. Through its reliance on this supply network for the purchase
of certain components, the Company is able to avoid many of the preproduction
and fixed costs associated with the manufacture of those components. The Company
maintains an extensive qualification and performance measurement system to
control risks associated with such reliance on suppliers. The Company
occasionally experiences problems with supplier and subcontractor performance
and must identify alternate sources of supply and/or address related warranty
claims from customers.
 
     While the Company purchases many costly components such as engines,
transmissions and axles, it manufactures certain proprietary components that are
deemed material to the Company's business. These components include front drive
and steer axles, transfer cases, cabs, the ALL-STEER electronic all-wheel
steering system, central tire inflation, independent suspension, the Sky-Arm
articulating aerial ladder, the McNeilus Auto Reach Arm, body structures and
many smaller parts which add uniqueness and value to the Company's products.
Some of these proprietary components are marketed to other manufacturers.
 
ENGINEERING, RESEARCH AND DEVELOPMENT
 
     The Company maintains three facilities for new product development and
testing with a staff of 46 engineers and technicians who are responsible for
improving existing products and development and testing of new trucks, truck
bodies and components. The Company prepares annual new product development and
improvement plans for each of its markets and measures progress against those
plans.
 
     Virtually all of the Company's sales of fire apparatus require some custom
engineering to meet the customer's specifications. Engineering is also a
critical factor in defense truck markets due to the severe operating conditions
under which the Company's trucks are utilized, new customer requirements and
stringent government documentation requirements. In the refuse truck body,
concrete mixer and snow equipment markets, product innovation is highly
important to meet customers' changing requirements. Accordingly, the Company
maintains a permanent staff of over 240 engineers and engineering technicians,
and it regularly outsources significant engineering activities in connection
with major DoD bids and proposals.
 
     For fiscal years 1997, 1996 and 1995, Oshkosh incurred engineering,
research and development expenditures of $7.8 million, $6.3 million and $5.4
million, respectively, portions of which were recoverable from customers,
principally the U.S. government.
 
INTELLECTUAL PROPERTY
 
     Patents and licenses are important in the operation of the Company's
business, as one of management's key objectives is developing proprietary
components in order to provide the Company's customers with advanced
technological solutions at attractive prices. The Company holds in excess of 50
active domestic patents. Management believes patents for all-wheel steer and
independent suspension systems, which have
 
                                       56
<PAGE>   60
 
remaining lives of 9 to 19 years, provide the Company with a competitive
advantage in the fire apparatus business and the sale of ARFF and snow removal
vehicles. The independent suspension system was also added to the U.S. Marine
Corps portion of the MTTR program, which the Company believes should be a
competitive advantage in the competition for the Phase II production contract.
Management believes that none of the Company's other patents individually are
significant to the business.
 
     The Company holds trademarks for "Oshkosh," "Pierce," "McNeilus" and "MTM."
These trademarks are considered to be important to the future success of the
Company's business.
 
QUALITY MANAGEMENT
 
     In 1994, Oshkosh commenced a program to educate and train all employees at
its Oshkosh facilities in quality principles and to seek ISO 9001 certification
to improve the Company's competitiveness in its global markets. Employees at all
levels of the Company are encouraged to understand customer and supplier
requirements, measure performance, develop systems and procedures to prevent
nonconformance with requirements and produce continuous improvement in all work
processes. In 1995, Oshkosh achieved ISO 9001 certification and Pierce is
targeting achievement of ISO 9001 certification in 1998. The Company is
evaluating whether to pursue ISO 9001 certification for McNeilus. Although
management does not consider such certification essential for McNeilus' domestic
markets, the Company may conclude it is valuable in marketing to certain
international customers.
 
EMPLOYEES
 
     As of December 31, 1997, on a pro forma basis, the Company had
approximately 3,500 employees, of which approximately 1,300, 1250 and 600
employees are located at its principal facilities in Oshkosh, Wisconsin,
Appleton, Wisconsin and Dodge Center, Minnesota, respectively. Production
workers totaling approximately 800 employees at the Company's Oshkosh facilities
are represented by the United Auto Workers union. The Company's five-year
contract with the United Auto Workers union extends through September 30, 2001.
The Company believes its relationship with employees is satisfactory.
 
MANUFACTURING
 
     The Company manufactures trucks and truck bodies at ten manufacturing
facilities. Employee involvement is encouraged to improve production processes
and product quality. In order to reduce production costs, the Company maintains
a continuing emphasis on the development of proprietary components,
self-sufficiency in fabrication, just-in-time inventory management, improvement
in production flows, interchangeability and simplification of components among
product lines, creation of jigs and fixtures to ensure repeatability of quality
processes, utilization of robotics, and performance measurement to assure
progress toward cost reduction targets.
 
     With the Acquisition, the Company intends to continue to upgrade its
manufacturing capabilities by adopting best practices across its manufacturing
facilities, relocating manufacturing activities to the most efficient facility,
investing in further fixturing and robotics, re-engineering manufacturing
processes and adopting lean manufacturing management practices across all
facilities.
 
     The Company plans to draw upon its recent experience with the Pierce
acquisition in integrating the McNeilus manufacturing facilities. Within the
first year following the Pierce acquisition, the Company consolidated three
Pierce manufacturing facilities down to two while increasing Pierce's capacity
by improving product flow. In addition, among other things, the Company reduced
the number of operating shifts at the Pierce paint plant from three to one to
substantially reduce utility costs, implemented indexing of production lines and
relocated chassis frame build-up to Oshkosh to improve production efficiencies,
and eliminated storage rooms to relocate inventory to point of use thereby
eliminating duplicate material handling.

PROPERTIES
 
     Management believes the Company's equipment and buildings are modern,
well-maintained and adequate for its present and anticipated needs. As of
December 31, 1997, on a pro forma basis, the Company operated in ten
manufacturing plants. In addition, the Company maintains twelve distribution
centers throughout the United States and four sales offices internationally. The
Company's manufacturing plants include:

     The Company's facilities are pledged as collateral under the terms of the
Senior Credit Facility.
 
     The Company's manufacturing facilities generally operate five days per week
on one shift, except for one week shutdowns in July and December. Management
believes the Company's manufacturing capacity could be approximately doubled
with limited capital spending by working an additional shift at each facility.
 
ENVIRONMENTAL MATTERS
 
     As part of its routine business operations, the Company disposes of and
recycles or reclaims certain industrial waste materials, chemicals and solvents
at third party disposal and recycling facilities which are licensed by
appropriate governmental agencies. In some instances, these facilities have been
and may be designated by the United States Environmental Protection Agency
("EPA") or a state environmental agency for remediation. Under CERCLA and
similar state laws, each potentially responsible party ("PRP") that contributed
hazardous substances may be jointly and severally liable for the costs
associated with cleaning up the site. Typically, PRPs negotiate a resolution
with the EPA and/or the state environmental agencies. PRPs also negotiate with
each other regarding allocation of the cleanup cost.
 
     At the Seaboard Chemical site located in Jamestown, North Carolina, Pierce
is one of 414 PRPs participating in the costs of addressing the site and has
been assigned an allocation share of approximately 0.04%. Currently a remedial
investigation/feasibility study is being completed, and as such, an estimate for
the total cost of the remediation of this site has not been made to date.
However, based on estimates and the assigned allocations, the Company believes
its liability at the site will not be material and its share is adequately
covered through reserves established by the Company at September 30, 1997.
Actual liability could vary based on results of the study, the resources of
other PRPs and the Company's final share of liability.
 
     The Company is addressing a regional trichloroethylene ("TCE") groundwater
plume on the south side of Oshkosh, Wisconsin. The Company believes there may be
multiple sources in the area. TCE was detected at the Company's North Plant
facility with recent testing showing the highest concentrations in a monitoring
well located on the upgradient property line. Because the investigation process
is still ongoing, it is not possible for the Company to estimate its long-term
total liability associated with this issue at this time. Also, as part of the
regional TCE groundwater investigation, the Company conducted a groundwater
investigation of a former landfill located on Company property. The landfill,
acquired by the Company in 1972, is approximately 2.0 acres in size and is
believed to have been used for the disposal of household waste. Based on the
investigation,
 
                                       58
<PAGE>   62
 
the Company does not believe the landfill is one of the sources of the TCE
contamination. Based upon current knowledge, the Company believes its liability
associated with the TCE issue will not be material and is adequately covered
through reserves established by the Company at September 30, 1997. However, this
may change as investigations proceed by the Company, other unrelated property
owners, and government entities.
 
     The Company is subject to other environmental matters which arise in the
ordinary course of business. Although the final results of all such matters
cannot be predicted with certainty, management believes that the ultimate
resolution of all such matters, after taking into account the liabilities
accrued with respect to such matters, will not have a material adverse effect on
the Company's financial condition or results of operations. Actual results could
vary, among other things, due to the uncertainties involved in environmental
investigations and remediation.
 
LEGAL PROCEEDINGS
 
     The Company is engaged in litigation against Super Steel Products
Corporation ("SSPC"), the Company's former supplier of mixer systems for
forward-discharge concrete mixer trucks under a long-term supply contract. SSPC
sued the Company in state court claiming the Company breached the contract. The
Company counterclaimed for repudiation of contract. On July 26, 1996, a jury
returned a verdict for SSPC awarding damages totaling $4.5 million. On October
10, 1996, the state court judge overturned the verdict against the Company,
granted judgment for the Company on its counterclaim, and ordered a new trial
for damages on the Company's counterclaim. Both SSPC and the Company have
appealed the state court judge's decision. The Wisconsin Court of Appeals has
agreed to hear the case and both the Company and SSPC have filed briefs in this
matter.
 
     The Company currently is engaged in the arbitration of certain disputes
between the Oshkosh Florida Division and O.V. Containers, Inc. ("OV"), which
arose out of the performance of a contract to deliver 690 skeletal container
chassis. The dispute involves a warranty claim originally filed in an
arbitration forum by OV against the Company in 1992. The Company settled the
arbitration, but subsequently obtained information that the failed chassis at
the heart of the dispute were subject to misuse and abuse and that certain
information requested at the time of the arbitration was improperly withheld.
The Company filed a lawsuit in the U.S. District Court for the Middle District
of Florida seeking damages of approximately $1.6 million. OV filed a demand for
arbitration of the matters underlying the Company's lawsuit, and successfully
stayed the Company's lawsuit pending the arbitration. OV has also asserted a
counterclaim in the arbitration for alleged breach of warranty and are seeking
damages of approximately $9.0 million. The arbitration is being conducted before
a three-member panel under the commercial dispute rules of the American
Arbitration Association, and is not expected to conclude before May 1998. The
Company is vigorously contesting warranty and other claims made against it, and
has asserted substantial claims against OV. The outcome of these matters cannot
be predicted at the present time.
 
     The Company is subject to other legal proceedings and claims, including
patent, antitrust and state dealership regulation compliance proceedings.
Although the final results of all such claims cannot be predicted with
certainty, management believes that the ultimate resolution of all claims, after
taking into account the liabilities accrued with respect to such claims, will
not have a material adverse effect on the Company's financial condition or
results of operations. Actual results could vary, among other things, due to the
uncertainties involved in litigation.

     During fiscal year 1997, and continuing through 1999, Oshkosh incurred and
will continue to incur rental expense of $128,400 per year under a lease between
Oshkosh and Cadence Company, a partnership of which Stephen P. Mosling and J.
Peter Mosling, Jr., together with their four sisters, are equal partners. The
lease relates to property and a building used by Oshkosh as a new product
development center. The lease will expire on July 31, 1999. Management believes
that the terms of the lease are at least as favorable as could be obtained in an
arm's length transaction with an unrelated third party.
 
     The Compensation Committee of Oshkosh's Board of Directors extended the
time for exercise of certain stock options held by Stephen P. Mosling and J.
Peter Mosling, Jr. to February 10, 1998. All of such options were exercised on
January 14, 1998.
 
     On April 10, 1997, in conjunction with the termination of the Strategic
Alliance Agreement entered into on June 5, 1995, with Freightliner, Oshkosh
repurchased for the sum of $6,750,000, 350,000 shares of Common Stock and
Warrants for the further purchase of 1,250,000 shares of Common Stock which had
been purchased by Freightliner on June 5, 1995, for the sum of $9,437,500.

                          DESCRIPTION OF INDEBTEDNESS
 
     The following sets forth information concerning the Company's indebtedness,
other than the Notes, outstanding immediately following the consummation of the
Transactions.
 
SENIOR CREDIT FACILITY
 
     The Company has entered into the Senior Credit Facility, pursuant to which
the Company has available a revolving credit facility (the "Revolving Credit
Facility"), and three term loan facilities ("Term Loan A," "Term Loan B" and
"Term Loan C" and, collectively, the "Term Loan Facility"). At the Closing, an
aggregate of $225.0 million under the Term Loan Facility was drawn under the
Senior Credit Facility, consisting of: (a) Term Loan A in the principal amount
$100.0 million, which matures on March 31, 2004; (b) Term Loan B in the
principal amount $62.5 million, which matures on March 31, 2005; and (c) Term
Loan C in the aggregate principal amount $62.5 million, which matures on March
31, 2006. The $100.0 million Revolving Credit Facility, which matures in
approximately six years, is available for working capital and general corporate
purposes, including the issuance of letters of credit, subject to compliance
with certain conditions. At the Closing, on a pro forma basis at December 31,
1997, approximately $13.0 million was drawn and an aggregate of approximately $8
million of letters of credit were issued and outstanding under the Revolving
Credit Facility.
 
     Term Loan A will amortize by $5.0 million in fiscal 1998, $11.0 million in
fiscal 1999, $13.5 million in fiscal 2000, $15.0 million in fiscal 2001, $19.5
million in fiscal 2002 and $24.0 million in fiscal 2003, with the remaining
outstanding balance due in fiscal 2004. Term Loan B and Term Loan C will each
have amortization of $156,250 per quarter, through March 31, 2004 for Term Loan
B and March 31, 2005 for Term Loan C, with the remaining outstanding balance of
Term Loan B and Term Loan C due in quarterly installments through March 31, 2005
and March 31, 2006, respectively.
 
     The initial interest rates applicable to the loans under the Senior Credit
Facility are equal to the Base Rate or, at the Company's election, the IBOR Rate
plus the Applicable Margins. As of the Closing, the Applicable Margins were as
follows:
 
<TABLE>
<CAPTION>
                 APPLICABLE MARGINS
                ---------------------
TYPE OF LOAN    BASE RATE   IBOR RATE
- ------------    ---------   ---------
<S>             <C>         <C>
Revolving Loan    0.75%       2.00%
Term Loan A       0.75%       2.00%
Term Loan B       1.00%       2.25%
Term Loan C       1.25%       2.50%
</TABLE>
 
     The initial rates for borrowings under the Revolving Credit Facility and
the Term Loan Facility remain in effect until the third business day following
delivery to the Administrative Agent of the Company's financial statements for
the quarter ending June 30, 1998, following which they may be increased or
reduced according to a pricing grid. The Company may elect interest periods of
one, two, three or six months for IBOR borrowings. For IBOR loans, interest is
calculated on the basis of actual days elapsed in a 360-day year and for Base
Rate loans calculated based on the reference rate, interest is calculated on the
number of days elapsed in a 365- or 366-day year, as applicable. Interest on
IBOR loans is payable at the end of each interest period, but not less
frequently than once every three months; interest on Base Rate loans is payable
on the last day of March, June, September and December of each year. The "IBOR
Rate" is the Administrative Agent's inter-bank offered rate for U.S. dollars in
off-shore markets. The "Base Rate" is higher of the Administrative Agent's
reference rate and the federal funds rate plus 0.5%.
 
     All domestic Restricted Subsidiaries of the Company other than MFSI
guarantee the Company's indebtedness under the Senior Credit Facility. All
extensions of credit under the Senior Credit Facility to the Company and the
guarantees of the Subsidiary Guarantors are secured by all existing and
after-acquired personal property of the Company and the Subsidiary Guarantors,
including all outstanding capital stock of the Company's domestic Restricted
Subsidiaries (other than, at the outset of the Transactions, MFSI) and 65% of
the outstanding capital stock of the Company's foreign Restricted Subsidiaries,
and any intercompany
 
                                       64
<PAGE>   68
 
debt obligations, and subject to exceptions agreed upon, all existing and
after-acquired real property fee and leasehold interests. With certain
exceptions agreed upon, the Company and its Restricted Subsidiaries (other than
MFSI) are prohibited from pledging any of their assets other than under the
Senior Credit Facility.
 
     Under the Senior Credit Facility, the letter of credit fee is equal to the
applicable IBOR margin for the Revolving Credit Facility, plus customary issuing
fees.
 
     Indebtedness under the Senior Credit Facility may be prepaid in whole or in
part without premium or penalty (subject in some cases to related IBOR breakage
costs) and the Lenders' commitments relative thereto reduced or terminated upon
such notice and in such amounts as may be agreed upon. Voluntary prepayments of
the Term Loan Facility will be applied to the Term Loan or Term Loans designated
by the Company to scheduled installments in order of maturity in the 12 months
following the date of such prepayment, with any excess applied pro rata to
scheduled installments of the designated Term Loans.
 
     The Company is required to make mandatory prepayments with respect to
excess cash flow (defined in the Senior Credit Facility), in an amount equal to
50.0% of such excess cash flow, payable on each January 15, beginning January
15, 1999.
 
     The Company is required to make mandatory prepayments with respect to all
proceeds of asset sales to the extent not applied to buy certain other fixed
assets.
 
     The Senior Credit Facility contains customary and appropriate
representations and warranties, including without limitation those relating to
due organization and authorization, no conflicts, financial condition, no
material adverse changes, title to properties, liens, litigation, payment of
taxes, compliance with laws, environmental liabilities and full disclosure.
 
     The conditions to all borrowings and issuances of letters of credit include
requirements relating to prior written notice of borrowing or issuance, the
accuracy of representations and warranties, and the absence of any default or
potential event of default, and will otherwise be customary and appropriate for
financings of this type.
 
     The Senior Credit Facility also contains customary affirmative and negative
covenants (including, where appropriate, certain exceptions and baskets mutually
agreed upon), including but not limited to furnishing information and
limitations on other indebtedness, liens, investments, guarantees, restricted
payments, mergers and acquisitions, sales of assets, capital expenditures,
leases, and affiliate transactions. The Senior Credit Facility also contains the
following financial covenants: minimum net worth; minimum fixed charge coverage
ratio; and maximum ratio of total debt to EBITDA.
 
     Events of default under the Senior Credit Facility are usual and customary,
including without limitation, those relating to: (i) non-payment of interest,
principal, fees or letter of credit obligations payable under the Senior Credit
Facility; (ii) non-performance of certain covenants; (iii) cross-default or
cross-acceleration to other material debt of the Company and its subsidiaries;
(iv) bankruptcy or insolvency; (v) unsatisfied judgments in excess of specified
amounts; (vi) impairment of security interests in collateral; (vii) invalidity
of guarantees; and (viii) materially inaccurate or false representations or
warranties.
 
LEASE FINANCING FACILITY
 
     The Leasing Partner entered into a general partnership with BALCAP, an
affiliate of the Initial Purchaser and Bank of America, effective February 26,
1998. The Leasing Partnership offers lease financing to customers of the Company
and administers existing lease transactions contributed to the partnership by
both partners. MFSI assigned to the Leasing Partner, which then contributed to
the Leasing Partnership, all of its current lease asset investments, which as of
November 30, 1997 had an aggregate total equipment value of approximately $122
million and associated liabilities of approximately $114 million. BALCAP has
contributed approximately $4.1 million of unencumbered lease assets to the
Leasing Partnership. BALCAP's initial net equity interest in the Leasing
Partnership therefore totals approximately 30.0% while the Leasing Partner's
interest is approximately 70.0%. Both the Leasing Partner and BALCAP are general
partners and the only partners of the Leasing Partnership. BALCAP acts as
managing partner of the Leasing Partnership. The
 
                                       65
<PAGE>   69
 
Leasing Partner acts as the tax matters partner of the Leasing Partnership and
also acts as the portfolio partner of the Leasing Partnership. The portfolio
partner services the Lease Assets conveyed by the Leasing Partner to the Leasing
Partnership and also services new Lease Assets originated by the Leasing
Partnership.
 
     The Leasing Partner has certain partnership obligations to BALCAP,
including the Company's obligation to offer future Lease Transactions to the
Leasing Partnership during the term of the Leasing Partnership. The Company will
indemnify the Leasing Partnership against losses relating to breaches of certain
representations and warranties made in connection with the conveyance of Lease
Assets to the Leasing Partnership by the Leasing Partner, as well as losses
relating to the performance of the Leasing Partner's obligations as the tax
matters partner and as portfolio partner.
 
     The Leasing Partnership manages the contributed assets and liabilities and
engages in new vendor lease business providing financing to customers of the
Company. The partners finance purchases of trucks to be leased to user-customers
by investing equity in an amount equal to approximately 11.0% to 14.0% of the
cost of the trucks. Banks and other lenders lend to the Leasing Partnership the
remaining percentage, with recourse solely to the Leasing Partnership, secured
by a pledge of the user-leases. Each partner funds one-half of the equity needed
to finance the new truck purchases, and each partner is allocated its
proportionate share of Leasing Partnership cash flow and taxable income.
Indebtedness under the Lease Financing Facility is secured by the underlying
leases and assets of, and is recourse to, the Leasing Partnership; such
indebtedness is off-balance sheet and non-recourse to the Company.

                          DESCRIPTION OF THE NEW NOTES
 
GENERAL
 
     The New Notes will be issued pursuant to the same Indenture (the
"Indenture") among the Company, the Subsidiary Guarantors and Firstar Trust
Company, as trustee (the "Trustee"), under which the Notes were issued. The
terms of the New Notes include those stated in the Indenture and those made part
of the Indenture by reference to the Trust Indenture Act of 1939 (the "Trust
Indenture Act"). The New Notes are subject to all such terms, and Holders of New
Notes are referred to the Indenture and the Trust Indenture Act for a statement
thereof. The following summary of the material provisions of the Indenture does
not purport to be complete and is qualified by reference to the Indenture,
including the definitions therein of certain terms used below. Copies of the
Indenture and Registration Rights Agreement are available as set forth below
under "-- Additional Information". The definitions of certain terms used in the
following summary are set forth below under "-- Certain Definitions." For
purposes of this summary, the term "Company" refers only to Oshkosh Truck
Corporation and not to any of its Subsidiaries.
 
     The New Notes will rank senior in right of payment to all subordinated
Indebtedness of the Company issued in the future, if any. The New Notes will be
general unsecured obligations of the Company and will be subordinated in right
of payment to all current and future Senior Debt. As of December 31, 1997, on a
pro forma basis giving effect to the Transactions, the Company would have had
Senior Debt of approximately $263.4 million. The Indenture permits the
incurrence of additional Senior Debt in the future.
 
     The operations of the Company are conducted in part through its
Subsidiaries, and the Company may, therefore, be dependent upon the cash flow of
its Subsidiaries to meet its debt obligations, including its obligations under
the New Notes. As of the date of this Prospectus, Nations Casualty Insurance,
Inc., a captive insurance company, and Oshkosh/McNeilus Financial Services,
Inc., a newly established Leasing Subsidiary, are the Company's only
Unrestricted Subsidiaries. MFSI, the Company's existing Leasing Subsidiary, is a
Restricted Subsidiary as of the date of this Prospectus, but is treated as if it
were an Unrestricted Subsidiary for purposes of certain of the restrictive
covenants set forth in the Indenture. Unrestricted Subsidiaries are subject to
many of the restrictive covenants set forth in the Indenture. Under certain
circumstances, the Company will be able to designate current or future
Subsidiaries, including MFSI, as Unrestricted Subsidiaries.
 
PRINCIPAL, MATURITY AND INTEREST
 
     The New Notes will be issued in an aggregate principal amount of up to
$100.0 million on or about the Expiration Date, and the Company may, subject to
the provisions of the Indenture, issue up to $50.0 million of additional New
Notes from time to time in the future. The New Notes will mature on March 1,
2008. Interest on the New Notes will accrue at the rate of 8 3/4% per annum and
will be payable semi-annually in arrears on March 1 and September 1, commencing
on September 1, 1998, to Holders of record on the immediately preceding February
15 and August 15. Interest on the New Notes will accrue from the most recent
date to which interest has been paid or, if no interest has been paid, from
February 26, 1998. Interest will be computed on the basis of a 360-day year
comprised of twelve 30-day months. Principal, premium, Liquidated Damages, if
any, and interest on the New Notes will be payable at the office or agency of
the Company maintained for such purpose within the City and State of New York
or, at the option of the Company, payment of interest and Liquidated Damages may
be made by check mailed to the Holders of the New Notes at their respective
addresses set forth in the register of Holders of New Notes; provided that all
payments of principal, premium, interest and Liquidated Damages with respect to
Holders of New Global Notes and New Notes the Holders of which have given wire
transfer instructions to the Company will be required to be made by wire
transfer of immediately available funds to the accounts specified by the Holders
thereof. Until otherwise designated by the Company, the Company's office or
agency in New York will be the office of the Trustee maintained for such
purpose. The New Notes will be issued in denominations of $1,000 and integral
multiples thereof.
 
                                       67
<PAGE>   71
 
SUBSIDIARY GUARANTEES
 
     The Company's payment obligations under the New Notes will be jointly and
severally guaranteed (the "Subsidiary Guarantees") by the Subsidiary Guarantors.
The Subsidiary Guarantee of each Subsidiary Guarantor will be subordinated to
the prior payment in full in cash or Cash Equivalents of all Senior Debt of such
Subsidiary Guarantor, which would include approximately $2.9 million of Senior
Debt outstanding as of December 31, 1997, and the amounts for which the
Subsidiary Guarantors are liable under the guarantees issued from time to time
with respect to Senior Debt. The obligations of each Subsidiary Guarantor under
its Subsidiary Guarantee are limited with the intention that such Subsidiary
Guarantee not constitute a fraudulent conveyance under applicable law. See,
however, "Risk Factors -- Fraudulent Conveyance Matters."
 
     The Indenture provides that no Subsidiary Guarantor may consolidate with or
merge with or into (whether or not such Subsidiary Guarantor is the surviving
Person) another corporation, Person or entity, whether or not affiliated with
such Subsidiary Guarantor unless: (i) subject to the provisions of the following
paragraph, the Person formed by or surviving any such consolidation or merger
(if other than such Subsidiary Guarantor) assumes all the obligations of such
Subsidiary Guarantor, pursuant to a supplemental indenture in form and substance
reasonably satisfactory to the Trustee, under the New Notes, the Indenture, the
Registration Rights Agreement and the Subsidiary Guarantees; (ii) immediately
after giving effect to such transaction, no Default or Event of Default exists;
and (iii) the Company would be permitted by virtue of the Company's pro forma
Fixed Charge Coverage Ratio, immediately after giving effect to such
transaction, to incur at least $1.00 of additional Indebtedness pursuant to the
Fixed Charge Coverage Ratio test set forth in the covenant described below under
the caption "Certain Covenants -- Incurrence of Indebtedness and Issuance of
Preferred Stock."
 
     The Indenture provides that in the event of a sale or other disposition of
all of the assets of any Subsidiary Guarantor, by way of merger, consolidation
or otherwise, or a sale or other disposition of all of the capital stock of any
Subsidiary Guarantor, then such Subsidiary Guarantor (in the event of a sale or
other disposition, by way of such a merger, consolidation or otherwise, of all
of the capital stock of such Subsidiary Guarantor) or the corporation acquiring
the property (in the event of a sale or other disposition of all of the assets
of such Subsidiary Guarantor) will be released and relieved of any obligations
under its Subsidiary Guarantee; provided that the Net Proceeds of such sale or
other disposition are applied in accordance with the applicable provisions of
the Indenture. See "Redemption or Repurchase at Option of Holders -- Asset
Sales."
 
SUBORDINATION
 
     The payment of principal of, premium, Liquidated Damages, if any, and
interest and other Obligations on the New Notes will be subordinated in right of
payment, as set forth in the Indenture, to the prior payment in full in cash or
Cash Equivalents of all Senior Debt, whether outstanding on the date of the
Indenture or thereafter incurred.
 
     Upon any distribution to creditors of the Company in a liquidation or
dissolution of the Company or in a bankruptcy, reorganization, insolvency,
receivership or similar proceeding relating to the Company or its property, an
assignment for the benefit of creditors or any marshaling of the Company's
assets and liabilities, the holders of Senior Debt will be entitled to receive
payment in full in cash or Cash Equivalents of all Obligations in respect of
such Senior Debt (including interest after the commencement of any such
proceeding at the rate specified in the applicable Senior Debt) before the
Holders of the New Notes will be entitled to receive any payment of cash,
properties or securities, with respect to the New Notes, and until all
Obligations with respect to Senior Debt are paid in full in cash or Cash
Equivalents, any distribution to which the Holders of the New Notes would be
entitled shall be made to the holders of Senior Debt (except that Holders of the
New Notes may receive and retain Permitted Junior Securities and payments made
from the trust described under the caption "-- Legal Defeasance and Covenant
Defeasance").
 
     The Company also may not directly or indirectly, (x) make any payment of
cash, properties or securities, upon or in respect of the New Notes (except in
Permitted Junior Securities or from the trust described under the caption "--
Legal Defeasance and Covenant Defeasance") or (y) acquire any of the New Notes
(except
                                       68
<PAGE>   72
 
in exchange for Permitted Junior Securities) if: (i) a default in the payment of
the principal of, premium, if any, interest or other Obligations on Significant
Senior Debt occurs and is continuing or (ii) any other default occurs and is
continuing with respect to Designated Senior Debt that permits holders of the
Designated Senior Debt as to which such other default relates to accelerate its
maturity and the Trustee receives a notice of such default (a "Payment Blockage
Notice") from the holders (or their Representative, if applicable) of any
Designated Senior Debt. Payments on the New Notes may and shall be resumed: (a)
in the case of a payment default, upon the date on which such default is cured
or waived and (b) in case of a nonpayment default, the earlier of the date on
which such nonpayment default is cured or waived or 179 days after the date on
which the applicable Payment Blockage Notice is received, unless the maturity of
any Designated Senior Debt has been accelerated in which case (a) above shall
become applicable. No new period of payment blockage may be commenced pursuant
to (ii) above unless and until: (i) 360 days have elapsed since the initial
effectiveness of the immediately prior Payment Blockage Notice and (ii) all
scheduled payments of principal, premium and Liquidated Damages, if any, and
interest on the New Notes that have come due have been paid in full in cash. No
nonpayment default that existed or was continuing on the date of delivery of any
Payment Blockage Notice to the Trustee shall be, or be made, the basis for a
subsequent Payment Blockage Notice unless such default shall have been cured or
waived for a period of not less than 180 days.
 
     The Indenture further requires that the Company promptly notify holders of
Senior Debt if payment of the New Notes is accelerated because of an Event of
Default.
 
     As a result of the subordination provisions described above, in the event
of a liquidation or insolvency, Holders of the New Notes may recover less
ratably than other creditors of the Company, including holders of Senior Debt.
See "Risk Factors -- Subordination." The Indenture limits, subject to certain
financial tests, the amount of additional Indebtedness, including Senior Debt,
that the Company and its subsidiaries can incur. See "-- Certain
Covenants -- Incurrence of Indebtedness and Issuance of Preferred Stock."
 
OPTIONAL REDEMPTION
 
     The New Notes will not be redeemable at the Company's option prior to March
1, 2003. Thereafter, the New Notes will be subject to redemption at any time at
the option of the Company, in whole or in part, upon not less than 30 nor more
than 60 days' notice, at the redemption prices (expressed as percentages of
principal amount) set forth below plus accrued and unpaid interest and
Liquidated Damages thereon, if any, to the applicable redemption date, if
redeemed during the twelve-month period beginning on March 1 of the years
indicated below:
 
<TABLE>
<CAPTION>

2006 and thereafter.........................................   100.000%
</TABLE>
 
     Notwithstanding the foregoing, at any time prior to March 1, 2001, the
Company may on any one or more occasions redeem up to 35% of the aggregate
principal amount of New Notes originally issued under the Indenture at a
redemption price of 108.750% of the principal amount thereof, plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the redemption date,
with the net cash proceeds of one or more public offerings of common stock of
the Company; provided that New Notes of an aggregate principal amount of at
least 65% of the aggregate principal amount of Notes issued on the date of the
Indenture remain outstanding immediately after the occurrence of such redemption
(excluding New Notes held by the Company and its Subsidiaries); and provided,
further, that such redemption shall occur within 45 days of the date of the
closing of such public offering.
 
SELECTION AND NOTICE
 
     If less than all of the New Notes are to be redeemed at any time, selection
of New Notes for redemption will be made by the Trustee in compliance with the
requirements of the principal national securities exchange,
 
                                       69
<PAGE>   73
 
if any, on which the New Notes are listed, or, if the New Notes are not so
listed, on a pro rata basis, by lot or by such method as the Trustee shall deem
fair and appropriate; provided that no New Notes of $1,000 or less shall be
redeemed in part. Notices of redemption shall be mailed by first class mail at
least 30 but not more than 60 days before the redemption date to each Holder of
New Notes to be redeemed at its registered address. Notices of redemption may
not be conditional. If any New Note is to be redeemed in part only, the notice
of redemption that relates to such New Note shall state the portion of the
principal amount thereof to be redeemed. A new 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 New Note. New Notes called for
redemption become due on the date fixed for redemption. On and after the
redemption date, interest ceases to accrue on New Notes or portions of them
called for redemption.
 
REPURCHASE AT THE OPTION OF HOLDERS
 
  CHANGE OF CONTROL
 
     Upon the occurrence of a Change of Control, each Holder of New Notes will
have the right to require the Company to repurchase all or any part (equal to
$1,000 or an integral multiple thereof) of such Holder's New Notes pursuant to
the offer described below (the "Change of Control Offer") at an offer price in
cash equal to 101% of the aggregate principal amount thereof plus accrued and
unpaid interest and Liquidated Damages thereon, if any, to the date of purchase
(the "Change of Control Payment"). Within 30 days following any Change of
Control, the Company will mail a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and offering
to repurchase New Notes on the date specified in such notice, which date shall
be no earlier than 30 days and no later than 60 days from the date such notice
is mailed (the "Change of Control Payment Date"), pursuant to the procedures
required by the Indenture and described in such notice. The Company will comply
with the requirements of Rule 14e-1 under the Exchange Act and any other
securities laws and regulations thereunder to the extent such laws and
regulations are applicable in connection with the repurchase of the New Notes as
a result of a Change of Control.
 
     On the Change of Control Payment Date, the Company will, to the extent
lawful: (i) accept for payment all New Notes or portions thereof properly
tendered pursuant to the Change of Control Offer; (ii) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all New
Notes or portions thereof so tendered; and (iii) deliver or cause to be
delivered to the Trustee the New Notes so accepted together with an Officers'
Certificate stating the aggregate principal amount of New Notes or portions
thereof being purchased by the Company. The Paying Agent will promptly mail to
each Holder of New Notes so tendered the Change of Control Payment for such New
Notes, and the Trustee will promptly authenticate and mail (or cause to be
transferred by book entry) to each Holder a new New Note equal in principal
amount to any unpurchased portion of the New Notes surrendered, if any; provided
that each such new New Note will be in a principal amount of $1,000 or an
integral multiple thereof. The Company will publicly announce the results of the
Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.
 
     The Change of Control provisions described above will be applicable whether
or not any other provisions of the Indenture are applicable. Except as described
above with respect to a Change of Control, the Indenture does not contain
provisions that permit the Holders of the New Notes to require that the Company
repurchase or redeem the New Notes in the event of a takeover, recapitalization
or similar transaction.
 
     The Senior Credit Agreement prohibits the Company from purchasing any New
Notes prior to their maturity and also provides that certain change of control
events with respect to the Company would constitute a default thereunder. Any
future credit agreements or other agreements relating to Senior Debt to which
the Company becomes a party may contain similar restrictions and provisions. The
Indenture provides that, prior to complying with the provisions of this
covenant, but in any event within 90 days following a Change of Control, the
Company will either repay all outstanding Senior Debt or obtain the requisite
consents, if any, under all agreements governing outstanding Senior Debt to
permit the repurchase of New Notes required by this covenant. If the Company
does not obtain such a consent or repay such borrowings, the Company will remain
prohibited from purchasing New Notes. In such case, the Company's failure to
purchase tendered New Notes would constitute an Event of Default under the
Indenture which would, in turn, constitute a
 
                                       70
<PAGE>   74
 
default under the Senior Credit Agreement. In such circumstances, the
subordination provisions in the Indenture would likely restrict payments to the
Holders of New Notes. There can be no assurance that upon a Change in Control
the Company would have sufficient assets to satisfy its obligation to purchase
all of the New Notes that might be delivered by Holders seeking to exercise
their repurchase right and any repurchase obligation under any Senior Debt then
outstanding.
 
     The Company will not be required to make a Change of Control Offer upon a
Change of Control if a third party makes the Change of Control Offer in the
manner, at the times and otherwise in compliance with the requirements set forth
in the Indenture applicable to a Change of Control Offer made by the Company and
purchases all New Notes validly tendered and not withdrawn under such Change of
Control Offer.
 
     The definition of Change of Control includes a phrase relating to the sale,
lease, transfer, conveyance or other disposition of "all or substantially all"
of the assets of the Company and its Subsidiaries taken as a whole. Although
there is a developing body of case law interpreting the phrase "substantially
all," there is no precise established definition of the phrase under applicable
law. Accordingly, the ability of a Holder of New Notes to require the Company to
repurchase such New Notes as a result of a sale, lease, transfer, conveyance or
other disposition of less than all of the assets of the Company and its
Subsidiaries taken as a whole to another Person or group may be uncertain.
 
  ASSET SALES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, consummate an Asset Sale unless: (i) the
Company (or the Restricted Subsidiary, as the case may be) receives
consideration at the time of such Asset Sale at least equal to the fair market
value (evidenced by a resolution of the Board of Directors set forth in an
Officers' Certificate delivered to the Trustee) of the assets or Equity
Interests issued or sold or otherwise disposed of and (ii) at least 75% of the
consideration therefor received by the Company or such Subsidiary is in the form
of cash; provided that the amount of (x) any liabilities (as shown on the
Company's or such Restricted Subsidiary's most recent balance sheet), of the
Company or any Restricted Subsidiary (other than contingent liabilities and
liabilities that are by their terms subordinated to the New Notes or any
guarantee thereof) that are assumed by the transferee of any such assets
pursuant to a customary novation agreement that releases the Company or such
Restricted Subsidiary from further liability and (y) any securities, notes or
other obligations received by the Company or any such Subsidiary from such
transferee that are contemporaneously (subject to ordinary settlement periods)
converted by the Company or such Restricted Subsidiary into cash (to the extent
of the cash received), shall be deemed to be cash for purposes of this
provision.
 
     Within 360 days after the receipt of any Net Proceeds from an Asset Sale,
the Company may apply such Net Proceeds, at its option, (a) to permanently
reduce Senior Debt (or, if such Senior Debt is revolving Indebtedness under a
Credit Facility, to permanently reduce any related commitments of lenders under
the Senior Debt (provided that such reductions shall have no effect on the
amount of Indebtedness permitted to be incurred pursuant to clause (ii)(b) of
the second paragraph of the covenant described under the caption "-- Certain
Covenants -- Incurrence of Indebtedness and Issuance of Preferred Stock")), or
(b) to the acquisition of a majority of the assets of, or a majority of the
Voting Stock of, another Permitted Business, the making of a capital expenditure
or the acquisition of other assets that are not classified as current assets
under GAAP and are used or useful in a Permitted Business. Pending the final
application of any such Net Proceeds, the Company may temporarily reduce
revolving credit borrowings or otherwise invest such Net Proceeds in any manner
that is not prohibited by the Indenture. Any Net Proceeds from Asset Sales that
are not applied or invested as provided in the first sentence of this paragraph
will be deemed to constitute "Excess Proceeds." When the aggregate amount of
Excess Proceeds exceeds $10.0 million, the Company will be required to make an
offer (pro rata in proportion to the principal amount (or accreted value, if
applicable) outstanding in respect of any asset sale offer required by the terms
of any pari passu Indebtedness incurred in accordance with the Indenture) to all
Holders of New Notes (an "Asset Sale Offer") to purchase the maximum principal
amount of New Notes that may be purchased out of the Excess Proceeds, at an
offer price in cash in an amount equal to 100% of the principal amount thereof
plus accrued and unpaid interest and Liquidated Damages thereon, if any, to the
date of purchase, in accordance with the procedures set forth in the Indenture.

                                       71
<PAGE>   75
 
To the extent that any Excess Proceeds remain after consummation of an Asset
Sale Offer, the Company may use such Excess Proceeds for any purpose not
otherwise prohibited by the Indenture. If the aggregate principal amount of New
Notes tendered into such Asset Sale Offer surrendered by Holders thereof (and
any pari passu Indebtedness, as aforesaid) exceeds the amount of Excess
Proceeds, the Trustee shall select the New Notes to be purchased on a pro rata
basis. Upon completion of such offer to purchase, the amount of Excess Proceeds
shall be reset at zero.
 
CERTAIN COVENANTS
 
  INCURRENCE OF INDEBTEDNESS AND ISSUANCE OF PREFERRED STOCK
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue,
assume, guarantee or otherwise become directly or indirectly liable,
contingently or otherwise, with respect to (collectively, "incur") any
Indebtedness (including Acquired Debt) and that the Company will not issue any
Disqualified Stock and will not permit any of its Restricted Subsidiaries to
issue any shares of preferred stock; provided, however, that the Company may
incur Indebtedness (including Acquired Debt) or issue shares of Disqualified
Stock and any Subsidiary Guarantor may incur Indebtedness or issue preferred
stock if the Fixed Charge Coverage Ratio for the Company's most recently ended
four full fiscal quarters for which internal financial statements are available
immediately preceding the date on which such additional Indebtedness is incurred
or such Disqualified Stock or preferred stock is issued would have been at least
2.0 to 1, determined on a pro forma basis (including a pro forma application of
the net proceeds therefrom), as if the additional Indebtedness had been
incurred, or the Disqualified Stock or preferred stock had been issued, as the
case may be, at the beginning of such four-quarter period.
 
     The provisions of the first paragraph of this covenant will not apply to
the incurrence of any of the following items of Indebtedness (collectively,
"Permitted Debt"):
 
          (i) the incurrence by the Company and the Subsidiary Guarantors of
     term Indebtedness under the Senior Credit Agreement (or, if the Senior
     Credit Agreement has matured or been terminated or repaid in whole or in
     part, any other Credit Facility); provided that the aggregate principal
     amount of all term Indebtedness outstanding under the Credit Facilities
     after giving effect to such incurrence does not exceed the greater of (a)
     the aggregate amount of term Indebtedness borrowed under the Senior Credit
     Agreement on the date of the Indenture less the aggregate amount of all
     repayments, optional or mandatory, of the principal of any term
     Indebtedness under the Senior Credit Agreement (other than payments that
     are immediately reborrowed) that have been made since the date of the
     Indenture and (b) $30.0 million;
 
          (ii) (a) the incurrence by the Company and the Subsidiary Guarantors
     of revolving Indebtedness and letters of credit pursuant to the Senior

     aggregate principal amount of all Indebtedness at any time outstanding
     under all Floor Plan Financing Facilities after giving effect to such
     incurrence does not exceed the total cost of the vehicles and equipment
     securing such Indebtedness;
 
          (iv) the incurrence by the Company or any of its Restricted
     Subsidiaries of the Existing Indebtedness;
 
          (v) the incurrence by the Company of Indebtedness represented by the
     New Notes and the incurrence by the Subsidiary Guarantors of the Subsidiary
     Guarantees;
 
          (vi) the incurrence by the Company or any of its Restricted
     Subsidiaries of Indebtedness represented by Capital Lease Obligations,

     permitted by this clause (viii);
 
          (ix) the incurrence by the Company or any of its Restricted

                                       73
<PAGE>   77
 
     agreements of the Company or any of its Restricted Subsidiaries providing
     for indemnification, adjustment of purchase price or similar obligations,
     in each case, incurred or assumed in connection with the disposition of any
     business, assets or Subsidiary, other than guarantees of Indebtedness
     incurred by any person acquiring all or any portion of such business,
     assets or Subsidiary for the purpose of financing such acquisition,
     provided that the maximum aggregate liability in respect of all such
     Indebtedness shall at no time exceed the gross proceeds actually received
     by the Company and its Subsidiaries in connection with such disposition;
 
          (xiv) the incurrence by a Leasing Subsidiary of Indebtedness in
     connection with a Leasing Transaction;
 
          (xv) the incurrence by the Company or any Restricted Subsidiary of
     Indebtedness in connection with the acquisition of assets or a new
     Subsidiary Guarantor; provided such Indebtedness was incurred by the prior
     owner of such assets or such Subsidiary Guarantor prior to such acquisition
     by the Company or one of its Subsidiary Guarantors and was not incurred in
     connection with, or in contemplation of, such acquisition by the Company or
     a Subsidiary Guarantor; and provided further that the principal amount (or
     accreted value, as applicable) of such Indebtedness, together with any
     other outstanding Indebtedness secured pursuant to this clause (xv) and any
     Permitted Refinancing Indebtedness incurred to refund, refinance or replace
     any Indebtedness incurred pursuant to this clause (xv), does not exceed
     $10.0 million; and
 
          (xvi) the incurrence by the Company or any of its Restricted
     Subsidiaries of additional Indebtedness in an aggregate principal amount
     (or accreted value, as applicable) at any time outstanding, including all
     Permitted Refinancing Indebtedness incurred to refund, refinance or replace
     any Indebtedness incurred pursuant to this clause (xvi), not to exceed
     $20.0 million; provided, however, that the principal amount (or accreted
     value, as applicable) of Indebtedness of Restricted Subsidiaries that are
     not Subsidiary Guarantors, at any time outstanding, including all Permitted
     Refinancing Indebtedness incurred to refund, refinance or replace any
     Indebtedness incurred pursuant to this clause (xvi), does not exceed $5.0
     million.
 
     For purposes of determining compliance with this covenant, in the event
that an item of Indebtedness meets the criteria of more than one of the
categories of Permitted Debt described in clauses (i) through (xvi) above or is
entitled to be incurred pursuant to the first paragraph of this covenant, the
Company shall, in its sole discretion, classify such item of Indebtedness in any
manner that complies with this covenant. Accrual of interest, accretion or
amortization of original issue discount, the payment of interest on any
Indebtedness in the form of additional Indebtedness with the same terms, and the
payment of dividends on Disqualified Stock in the form of additional shares of
the same class of Disqualified Stock will not be deemed to be an incurrence of
Indebtedness or an issuance of Disqualified Stock for purposes of this covenant;
provided, in each such case, that the amount thereof is included in Fixed
Charges of the Company as accrued. Nothing in this covenant shall prohibit the
incurrence by the Company's Unrestricted Subsidiaries of Non-Recourse Debt
(excluding Indebtedness owed by such Unrestricted Subsidiary to the Company);
provided, however, that if any such Indebtedness ceases to be Non-Recourse Debt
of an Unrestricted Subsidiary, such event shall be deemed to constitute an
incurrence of Indebtedness by a Restricted Subsidiary of the Company.
 
  RESTRICTED PAYMENTS
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly: (i) declare or pay
any dividend or make any other payment or distribution on account of the
Company's or any of its Restricted Subsidiaries' Equity Interests (including,
without limitation, any payment in connection with any merger or consolidation
involving the Company or any of its Restricted Subsidiaries) or to the direct or
indirect holders of the Company's or any of its Restricted Subsidiaries' Equity
Interests in their capacity as such (other than dividends or distributions
payable in Equity Interests (other than Disqualified Stock) of the Company or to
the Company or a Restricted Subsidiary of the Company); (ii) purchase, redeem or
otherwise acquire or retire for value (including, without limitation, in
connection with any merger or consolidation involving the Company) any Equity
Interests of the Company, (iii) make any payment on or with respect to, or
purchase, redeem, defease or otherwise acquire or retire for value any
 
                                       74
<PAGE>   78
 
Indebtedness that is subordinated to the New Notes, except a payment of interest
or principal at Stated Maturity; or (iv) make any Restricted Investment (all
such payments and other actions set forth in clauses (i) through (iv) above
being collectively referred to as "Restricted Payments"), unless, at the time of
and after giving effect to such Restricted Payment:
 
          (a) no Default or Event of Default shall have occurred and be
     continuing or would occur as a consequence thereof; and
 
          (b) the Company would, at the time of such Restricted Payment and
     after giving pro forma effect thereto as if such Restricted Payment had
     been made at the beginning of the applicable four-quarter period, have been
     permitted to incur at least $1.00 of additional Indebtedness pursuant to
     the Fixed Charge Coverage Ratio test set forth in the first paragraph of
     the covenant described above under caption "-- Incurrence of Indebtedness
     and Issuance of Preferred Stock"; and
 
          (c) such Restricted Payment, together with the aggregate amount of all
     other Restricted Payments made by the Company and its Subsidiaries after
     the date of the Indenture (excluding Restricted Payments permitted by
     clauses (ii), (iii) and (iv) of the next succeeding paragraph), is less
     than the sum, without duplication, of (i) 50% of the Consolidated Net
     Income of the Company for the period (taken as one accounting period) from
     the beginning of the first fiscal month commencing after the date of the
     Indenture to the end of the Company's most recently ended fiscal quarter
     for which internal financial statements are available at the time of such
     Restricted Payment (or, if such Consolidated Net Income for such period is
     a deficit, less 100% of such deficit), plus (ii) 100% of the aggregate net
     cash proceeds received by the Company since the date of the Indenture as a
     contribution to its common equity capital or from the issue or sale of
     Equity Interests of the Company (other than Disqualified Stock) or from the
     issue or sale of Disqualified Stock or debt securities of the Company that
     have been converted into such Equity Interests (other than Equity Interests
     (or Disqualified Stock or convertible debt securities) sold to a Subsidiary
     of the Company), plus (iii) to the extent that any Restricted Investment
     that was made after the date of the Indenture is sold for cash or otherwise
     liquidated or repaid for cash, the lesser of (A) the cash return of capital
     with respect to such Restricted Investment (less the cost of disposition,
     if any) and (B) the initial amount of such Restricted Investment, plus (iv)
     50% of any cash dividends or other cash distributions received by the
     Company or a Restricted Subsidiary that is a Subsidiary Guarantor after the
     date of the Indenture from MFSI or an Unrestricted Subsidiary of the
     Company (other than dividends or distributions made by Nations Casualty
     Insurance, Inc.), to the extent that such dividends or other cash
     distributions were not otherwise included in Consolidated Net Income of the
     Company for such period, plus (v) to the extent that any Unrestricted
     Subsidiary designated as such after the date of the Indenture is
     redesignated as a Restricted Subsidiary after the date of the Indenture,
     the lesser of (A) the fair market value of the Company's Investment in such
     Subsidiary as of the date of such redesignation or (B) such fair market
     value as of the date on which such Subsidiary was originally designated as
     an Unrestricted Subsidiary, plus (vi) after the sale or liquidation of
     Nations Casualty Insurance, Inc., 50% of the excess of (A) any cash
     dividends or other cash distributions received by the Company or a
     Subsidiary Guarantor after the date of the Indenture from Nations Casualty
     Insurance, Inc. over (B) any Investment in Nations Casualty Insurance, Inc.
     permitted pursuant to clause (h) of the definition of Permitted
     Investments, plus (vii) other Restricted Payments in an aggregate amount
     not to exceed $5.0 million.
 
     The foregoing provisions will not prohibit: (i) the payment of any dividend
within 60 days after the date of declaration thereof, if at said date of
declaration such payment would have complied with the provisions of the
Indenture; (ii) the redemption, repurchase, retirement, defeasance or other
acquisition of any subordinated Indebtedness or Equity Interests of the Company
in exchange for, or out of the net cash proceeds of the substantially concurrent
sale (other than to a Subsidiary of the Company) of, other Equity Interests of
the Company (other than any Disqualified Stock); provided that the amount of any
such net cash proceeds that are utilized for any such redemption, repurchase,
retirement, defeasance or other acquisition shall be excluded from clause (c)
(ii) of the preceding paragraph; (iii) the defeasance, redemption, repurchase or
other acquisition of subordinated Indebtedness with the net cash proceeds from
an incurrence of Permitted Refinancing Indebtedness; (iv) the payment of any
dividend by a Subsidiary of the Company to the holders of its common Equity
Interests on a pro rata basis; and (v) the repurchase, redemption or other
acquisition or
                                       75
<PAGE>   79
 
retirement for value of any Equity Interests of the Company or any Subsidiary of
the Company held by any member of the Company's (or any of its Subsidiaries')
management pursuant to any management equity subscription agreement or stock
option agreement in effect as of the date of the Indenture; provided that the
aggregate price paid for all such repurchased, redeemed, acquired or retired
Equity Interests shall not exceed $1.0 million in any twelve-month period and
shall not at any time exceed $5.0 million in the aggregate and no Default or
Event of Default shall have occurred and be continuing immediately after such
transaction; (vi) Investments in securities not constituting cash or Cash
Equivalents and received in connection with an Asset Sale made pursuant to the
provisions of the covenant described under "-- Certain Covenants -- Limitation
on Asset Sales" above or any other disposition of assets not constituting an
Asset Sale by reason of the threshold contained in the definition thereof; and
(vii) repurchases of Equity Interests deemed to occur upon exercise of stock
options if such Equity Interests represent a portion of the exercise price of
such options.
 
     The Board of Directors may designate any Restricted Subsidiary to be an
Unrestricted Subsidiary if such designation would not cause a Default; provided
that in no event shall all or substantially all of the business currently
operated by the Company, McNeilus Truck & Manufacturing Inc., or Pierce
Manufacturing Inc. be transferred to or held by an Unrestricted Subsidiary. For
purposes of making such determination, all outstanding Investments by the
Company and its Restricted Subsidiaries (except to the extent repaid in cash) in
the Subsidiary so designated will be deemed to be Restricted Payments at the
time of such designation and will reduce the amount available for Restricted
Payments under the first paragraph of this covenant. All such outstanding
Investments will be deemed to constitute Investments in an amount equal to the
fair market value of such Investments at the time of such designation. Such
designation will only be permitted if such Restricted Payment would be permitted
at such time and if such Restricted Subsidiary otherwise meets the definition of
an Unrestricted Subsidiary.
 
     The amount of all Restricted Payments (other than cash) shall be the fair
market value on the date of the Restricted Payment of the asset(s) or securities
proposed to be transferred or issued by the Company or such Subsidiary, as the
case may be, pursuant to the Restricted Payment. The fair market value of any
non-cash Restricted Payment shall be determined by the Board of Directors whose
resolution with respect thereto shall be delivered to the Trustee, such
determination to be based upon an opinion or appraisal issued by an accounting,
appraisal or investment banking firm of national standing if such fair market
value exceeds $5.0 million. Not later than five Business Days after making any
Restricted Payment, the Company shall deliver to the Trustee an Officers'
Certificate stating that such Restricted Payment is permitted and setting forth
the basis upon which the calculations required by the covenant "Restricted
Payments" were computed, together with a copy of any fairness opinion or
appraisal required by the Indenture.
 
  LIENS
 
     The Indenture provides that the Company will not, and will not permit any
of its Subsidiaries to, directly or indirectly, create, incur, assume or suffer
to exist any Lien securing Indebtedness or trade payables on any asset now owned
or hereafter acquired, or any income or profits therefrom or assign or convey
any right to receive income therefrom, except Permitted Liens.
 
  DIVIDEND AND OTHER PAYMENT RESTRICTIONS AFFECTING SUBSIDIARIES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, directly or indirectly, create or otherwise
cause or suffer to exist or become effective any encumbrance or restriction on
the ability of any Restricted Subsidiary to: (i)(a) pay dividends or make any
other distributions to the Company or any of its Restricted Subsidiaries (1) on
its Capital Stock or (2) with respect to any other interest or participation in,
or measured by, its profits, or (b) pay any indebtedness owed to the Company or
any of its Restricted Subsidiaries; (ii) make loans or advances to the Company
or any of its Restricted Subsidiaries; or (iii) transfer any of its properties
or assets to the Company or any of its Restricted Subsidiaries. However, the
foregoing restrictions will not apply to encumbrances or restrictions existing
under or by reason of (a) Existing Indebtedness or the Senior Credit Agreement
as in effect as of the date of the Indenture, and any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or
refinancings thereof, provided that the provisions contained in such amendments,

                                       76
<PAGE>   80
 
modifications, restatements, renewals, increases, supplements, refundings,
replacement or refinancings are no more restrictive, taken as a whole, with
respect to such dividend and other payment restrictions than those contained in
the Senior Credit Agreement or the agreement governing such Existing
Indebtedness, as applicable, as in effect on the date of the Indenture, (b) the
Indenture and the New Notes, (c) applicable law, (d) any instrument governing
Indebtedness or Capital Stock of a Person acquired by the Company or any of its
Restricted Subsidiaries as in effect at the time of such acquisition (except to
the extent such Indebtedness was incurred in connection with or in contemplation
of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the
property or assets of the Person, so acquired, provided that, in the case of
Indebtedness, such Indebtedness was permitted by the terms of the Indenture to
be incurred by the acquiring Company or Restricted Subsidiary, as applicable, at
the time of such acquisition, (e) customary non-assignment provisions in leases
entered into in the ordinary course of business and consistent with past
practices, (f) purchase money obligations for property acquired in the ordinary

(iii) above on the property so acquired, (g) any agreement for the sale of a
Restricted Subsidiary that restricts distributions by that Restricted Subsidiary
pending its sale, (h) Permitted Refinancing Indebtedness, provided that the

the agreements governing the Indebtedness being refinanced, (i) secured
Indebtedness otherwise permitted to be incurred pursuant to the provisions of
the covenant described above under the caption "-- Liens" that limits the right
of the debtor to dispose of the assets securing such Indebtedness, (j) any
Indebtedness incurred by a Foreign Subsidiary pursuant to clause (ii)(c) of the
second paragraph of the covenant described above under the caption "--
Indebtedness and Issuance of Preferred Stock," (k) provisions with respect to
the disposition or distribution of assets or property in an Asset Sale (or in a
transaction which, but for it size, would be an Asset Sale), or in joint venture
agreements and other similar agreements entered into in the ordinary course of
business and (l) restrictions on cash or other deposits or net worth imposed by
customers under contracts entered into in the ordinary course of business.
 
  MERGER, CONSOLIDATION, OR SALE OF ASSETS
 
     The Indenture provides that the Company may not consolidate or merge with
or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of its properties or assets in one or more related transactions, to another
corporation, Person or entity unless: (i) the Company is the surviving
corporation or the entity or the Person formed by or surviving any such
consolidation or merger (if other than the Company) or to which such sale,
assignment, transfer, lease, conveyance or other disposition shall have been
made is a corporation organized or existing under the laws of the United States,
any state thereof or the District of Columbia; (ii) the entity or Person formed
by or surviving any such consolidation or merger (if other than the Company) or

Company under the Registration Rights Agreement, the New Notes and the Indenture
pursuant to a supplemental indenture in a form reasonably satisfactory to the
Trustee; (iii) immediately after such transaction no Default or Event of Default
exists; and (iv) except in the case of a merger of the Company with or into a
Wholly Owned Restricted Subsidiary of the Company, the Company or the entity or
Person formed by or surviving any such consolidation or merger (if other than
the Company), or to which such sale, assignment, transfer, lease, conveyance or
other disposition shall have been made will, at the time of such transaction and
after giving pro forma effect thereto as if such transaction had occurred at the
beginning of the applicable four-quarter period, be permitted to incur at least
$1.00 of additional Indebtedness pursuant to the Fixed Charge Coverage Ratio
test set forth in the first paragraph of the covenant described above under the
caption "-- Incurrence of Indebtedness and Issuance of Preferred Stock."
 
  TRANSACTIONS WITH AFFILIATES
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer
or otherwise dispose of any of its properties or assets to, or purchase any
property or assets from, or enter into or make or amend any transaction,
contract, agreement,
                                       77
<PAGE>   81
 
understanding, loan, advance or guarantee with, or for the benefit of, any
Affiliate (each of the foregoing, an "Affiliate Transaction"), unless: (i) such
Affiliate Transaction is on terms that are no less favorable to the Company or
the relevant Subsidiary than those that would have been obtained in a comparable
transaction by the Company or such Subsidiary with an unrelated Person; and (ii)
the Company delivers to the Trustee (a) with respect to any Affiliate
Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $1.0 million, a resolution of the Board of Directors
set forth in an Officers' Certificate certifying that such Affiliate Transaction
complies with clause (i) above and that such Affiliate Transaction has been
approved by a majority of the disinterested members of the Board of Directors
and (b) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration in excess of $5.0 million, an

shall not be deemed to be Affiliate Transactions: (i) any employment or
severance agreement and any amendment thereto entered into by the Company or any
of its Subsidiaries in the ordinary course of business; (ii) transactions

between or among the Company or any Restricted Subsidiary and any Leasing
Subsidiary in the ordinary course of business (including the contribution of
overhead costs consistent with past practice and in the ordinary course of

the benefit of any Leasing Subsidiary (whether undertaken in connection with a
lease securitization or other transaction involving any Leasing Subsidiary),

  SALE AND LEASEBACK TRANSACTIONS
 
     The Indenture provides that the Company will not, and will not permit any
of its Restricted Subsidiaries to, enter into any sale and leaseback
transaction; provided that the Company may enter into a sale and leaseback
transaction if: (i) the Company could have (a) incurred Indebtedness in an
amount equal to the Attributable Debt relating to such sale and leaseback
transaction pursuant to the Fixed Charge Coverage Ratio test set forth in the
first paragraph of the covenant described above under the caption "-- Incurrence
of Additional Indebtedness and Issuance of Preferred Stock" and (b) incurred a
Lien to secure such Indebtedness pursuant to the covenant described above under

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 the Company applies the proceeds of
such transaction in compliance with, the covenant described above under the
caption "Repurchase at the Option of the Holders -- Asset Sales."

  BUSINESS ACTIVITIES
 
     The Company will not, and will not permit any Restricted Subsidiary to,
engage in any business other than Permitted Businesses, except to such extent as
would not be material to the Company and its Subsidiaries taken as a whole.
 
  PAYMENTS FOR CONSENT
 
     The Indenture provides that neither the Company nor any of its Restricted
Subsidiaries will, directly or indirectly, pay or cause to be paid any
consideration, whether by way of interest, fee or otherwise, to any Holder of
any New Notes for or as an inducement to any consent, waiver or amendment of any
of the terms or provisions of the Indenture or the New Notes unless such
consideration is offered to be paid or is paid to all Holders of the New Notes
that consent, waive or agree to amend in the time frame set forth in the
solicitation documents relating to such consent, waiver or agreement.
 
  NO SENIOR SUBORDINATED DEBT
 
     The Indenture provides that: (i) the Company will not incur, create, issue,
assume, guarantee or otherwise become liable for any Indebtedness that is
subordinate or junior in right of payment to any Senior Debt and senior in any
respect in right of payment to the New Notes; and (ii) no Subsidiary Guarantor
will incur, create, issue, assume, guarantee or otherwise become liable for any
Indebtedness that is subordinate or junior in right of payment to Guarantees of
Senior Debt or to Senior Debt of such Subsidiary Guarantor and senior in any
respect in right of payment to the Subsidiary Guarantees.
 
  ADDITIONAL SUBSIDIARY GUARANTEES
 
     The Indenture provides that (i) if the Company or any of its Restricted
Subsidiaries shall, after the date of the Indenture, transfer or cause to be
transferred, including by way of any Investment, in one or a series of
transactions (whether or not related), any assets, businesses, divisions, real
property or equipment having an aggregate fair market value (as determined in
good faith by the Board of Directors) in excess of $1.0 million to any
Restricted Subsidiary (other than any Leasing Subsidiary) that is not a
Subsidiary Guarantor or a Foreign Subsidiary, (ii) if the Company or any of its
Restricted Subsidiaries shall acquire another Restricted Subsidiary other than a
Foreign Subsidiary having total assets with a fair market value (as determined
in good faith by the Board of Directors) in excess of $1.0 million, or (iii) if
any Restricted Subsidiary other than a Foreign Subsidiary shall incur
Indebtedness in excess of $1.0 million, then the Company shall, at the time of
such transfer, acquisition or incurrence cause such Restricted Subsidiary that
is the transferee of such transfer, is so acquired, or incurs such Indebtedness
(if not then a Subsidiary Guarantor) to become a Subsidiary Guarantor and
execute a Supplemental Indenture and deliver an Opinion of Counsel, in
accordance with the terms of the Indenture; provided, that: (i) the Subsidiary
Guarantee of such Subsidiary Guarantor may be subordinated to Senior Debt of
such Subsidiary Guarantor; and (ii) such Restricted Subsidiary shall not be
required to issue a Subsidiary Guarantee if such Restricted Subsidiary is a
Foreign Subsidiary and such Foreign Subsidiary has not guaranteed and does not
guarantee any other Indebtedness of the Company or any other Restricted
Subsidiary of the Company that is not a Foreign Subsidiary.
 
  LIMITATION ON ISSUANCES AND SALES OF EQUITY INTERESTS IN WHOLLY OWNED
RESTRICTED SUBSIDIARIES
 
     The Indenture provides that the Company (i) will not, and will not permit
any Wholly Owned Restricted Subsidiary of the Company to, transfer, convey,
sell, lease or otherwise dispose of any Equity Interests in any Wholly Owned
Restricted Subsidiary of the Company to any Person (other than the Company or a
Wholly Owned Restricted Subsidiary of the Company), unless (a) such transfer,
conveyance, sale, lease or other disposition is of all the Equity Interests in
such Wholly Owned Restricted Subsidiary and (b) the cash Net Proceeds from such
transfer, conveyance, sale, lease or other disposition are applied in accordance
with the covenant described above under the caption "-- Asset Sales," and (ii)
will not permit any Wholly Owned Restricted Subsidiary of the Company to issue
any of its Equity Interests (other than, if necessary, shares of
 
                                       79
<PAGE>   83
 
its Capital Stock constituting directors' qualifying shares) to any Person other
than to the Company or a Wholly Owned Restricted Subsidiary of the Company.
 
  REPORTS
 
     The Indenture provides that, whether or not required by the rules and
regulations of the Commission, so long as any New Notes are outstanding, the
Company will furnish to the Holders of Notes: (i) all quarterly and annual
financial information that would be required to be contained in a filing with
the Commission on Forms 10-Q and 10-K if the Company were required to file such
Forms, including a "Management's Discussion and Analysis of Consolidated
Financial Condition and Results of Operations" that describes the financial
condition and results of operations of the Company and its consolidated
Subsidiaries (showing in reasonable detail, either on the face of the financial
statements or in the footnotes thereto, the financial condition and results of
operations of the Company and its Restricted Subsidiaries separate from the
financial condition and results of operations of the Unrestricted Subsidiaries
of the Company, if material) and, with respect to the annual information only, a
report thereon by the Company's certified independent accountants and (ii) all
current reports that would be required to be filed with the Commission on Form
8-K if the Company were required to file such reports, in each case within the
time periods specified in the Commission's rules and regulations. In addition,
following the consummation of this Exchange Offer, whether or not required by
the rules and regulations of the Commission, the Company will file a copy of all
such information and reports with the Commission for public availability within
the time periods specified in the Commission's rules and regulations (unless the
Commission will not accept such a filing) and make such information available to
securities analysts and prospective investors upon request. In addition, the
Company and the Subsidiary Guarantors have agreed that, for so long as any New
Notes remain outstanding (unless the Company is subject to the reporting
requirements of the Exchange Act), they will furnish to the Holders and to
securities analysts and prospective investors, upon their request, the
information required to be delivered pursuant to Rule 144A(d)(4) under the
Securities Act.
 
  EVENTS OF DEFAULT AND REMEDIES
 
     The Indenture provides that each of the following constitutes an Event of
Default: (i) default for 30 days in the payment when due of interest on, or
Liquidated Damages with respect to, the New Notes (whether or not prohibited by
the subordination provisions of the Indenture); (ii) default in payment when due
of the principal of or premium, if any, on the New Notes whether or not
prohibited by the subordination provisions of the Indenture); (iii) failure by
the Company or any of its Subsidiaries to comply with the provisions described
under the captions "-- Repurchase at the Option of the Holder -- Change of
Control," "Repurchase at the Option of the Holder -- Asset Sales," "Certain
Covenants -- Restricted Payments," "Certain Covenants -- Incurrence of
Indebtedness and Issuance of Preferred Stock," or "Merger, Consolidation or Sale
of Assets"; (iv) failure by the Company or any of its Subsidiaries for 60 days
after notice from the Trustee or the Holders of at least 25% in principal amount
of the outstanding New Notes to comply with any of its other agreements in the
Indenture or the New Notes; (v) 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 the Company or any of its
Subsidiaries (or the payment of which is guaranteed by the Company or any of its
Subsidiaries) whether such Indebtedness or guarantee now exists, or is created
after the date of the Indenture, which default (a) is caused by a failure to pay
principal of or premium, if any, or interest on such Indebtedness prior to the
expiration of the grace period provided in such Indebtedness on the date of such
default (a "Payment Default") or (b) results in the acceleration of such
Indebtedness prior to its express maturity and, in each case, the principal
amount of any such Indebtedness, 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; (vi) failure
by the Company or any of its Subsidiaries to pay final judgments aggregating in
excess of $5.0 million, which judgments are not paid, discharged or stayed for a
period of 60 days; (vii) except as permitted by the Indenture, any Subsidiary
Guarantee shall be held in any judicial proceeding to be unenforceable or
invalid or shall cease for any reason to be in full force and effect or any
Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary
Guarantor, shall
 
                                       80
<PAGE>   84
 
deny or disaffirm its obligations under its Subsidiary Guarantee; and (viii)
certain events of bankruptcy or insolvency with respect to the Company or any of
its Significant Subsidiaries.
 
     If any Event of Default occurs and is continuing, the Trustee or the
Holders of at least 25% in principal amount of the then outstanding New Notes
may declare all the New Notes to be due and payable by notice in writing to the
Company and the Trustee specifying the respective Event of Default and that it
is a "notice of acceleration" (the "Acceleration Notice") and the same (i) shall
become immediately due and payable or (ii) if there are any amounts outstanding
under the Senior Credit Agreement, shall become due and payable upon the first
to occur of an acceleration under the Senior Credit Agreement, or five business
days after receipt by the Company and the Representative under the Senior Credit
Agreement of such Acceleration Notice. In the event of a declaration of
acceleration because an Event of Default set forth in clause (v) of the
preceding paragraph has occurred and is continuing, such declaration of
acceleration shall be automatically annulled if (A) the missed payments in
respect of the applicable Indebtedness have been paid or if the holders of the
Indebtedness that is subject to acceleration have rescinded their declaration of
acceleration, in each case within 60 days thereof and (B) all existing Events of
Default, except non-payment of principal or interest which have become due
solely because of the acceleration of the New Notes, have been cured or waived.
Notwithstanding the foregoing, in the case of an Event of Default arising from
certain events of bankruptcy or insolvency, with respect to the Company, any
Subsidiary Guarantor constituting a Significant Subsidiary or any group of
Subsidiary Guarantors that, taken together, would constitute a Significant
Subsidiary, all outstanding New Notes will become due and payable without
further action or notice. Holders of the New Notes may not enforce the Indenture
or the New Notes except as provided in the Indenture. Subject to certain
limitations, Holders of a majority in principal amount of the then outstanding
New Notes may direct the Trustee in its exercise of any trust or power. The
Trustee may withhold from Holders of the New Notes notice of any continuing
Default or Event of Default (except a Default or Event of Default relating to
the payment of principal or interest) if it determines that withholding notice
is in their interest.
 
     In the case of any Event of Default occurring by reason of any willful
action (or inaction) taken (or not taken) by or on behalf of the Company with
the intention of avoiding payment of the premium that the Company would have had
to pay if the Company then had elected to redeem the New Notes pursuant to the
optional redemption provisions of the Indenture, an equivalent premium shall
also become and be immediately due and payable to the extent permitted by law
upon the acceleration of the New Notes. If an Event of Default occurs prior to
March 1, 2003 by reason of any willful action (or inaction) taken (or not taken)
by or on behalf of the Company with the intention of avoiding the prohibition on
redemption of the New Notes prior to March 1, 2003, then the premium specified
in the Indenture shall also become immediately due and payable to the extent
permitted by law upon the acceleration of the New Notes.
 
     The Holders of a majority in aggregate principal amount of the New Notes
then outstanding by notice to the Trustee may on behalf of the Holders of all of
the New Notes waive any existing Default or Event of Default and its
consequences under the Indenture except a continuing Default or Event of Default
in the payment of interest on, or the principal of, the New Notes.
 
     The Company is required to deliver to the Trustee annually a statement
regarding compliance with the Indenture, and the Company is required upon
becoming aware of any Default or Event of Default, to deliver to the Trustee a
statement specifying such Default or Event of Default.
 
  NO PERSONAL LIABILITY OF DIRECTORS, OFFICERS, EMPLOYEES AND SHAREHOLDERS UNDER
NEW NOTES
 
     No director, officer, employee, incorporator or shareholder of the Company
or any Subsidiary Guarantor, as such, shall have any liability for any
obligations of the Company or any Subsidiary Guarantor under the New Notes, the
Indenture or the Subsidiary Guarantees or for any claim based on, in respect of,
or by reason of, such obligations or their creation. Each Holder of New Notes by
accepting a New Note waives and releases all such liability. The waiver and
release are part of the consideration for issuance of the New Notes and the
Subsidiary Guarantees. However, such waiver may not be effective to waive
liabilities under the federal securities laws, including, but not limited to,
liability under Section 11 of the Securities Act, and it is the view of the
Commission that such a waiver is not effective and is against public policy.

<PAGE>   85
 
  LEGAL DEFEASANCE AND COVENANT DEFEASANCE
 
     The Company may, at its option and at any time, elect to have all of its
obligations discharged with respect to the outstanding New Notes ("Legal
Defeasance") except for: (i) the rights of Holders of outstanding New Notes to
receive payments in respect of the principal of, premium, if any, and interest
and Liquidated Damages on such New Notes when such payments are due from the
trust referred to below; (ii) the Company's obligations with respect to the New
Notes concerning issuing temporary New Notes, registration of New Notes,
mutilated, destroyed, lost or stolen New Notes and the maintenance of an office
or agency for payment and money for security payments held in trust; (iii) the
rights, powers, trusts, duties and immunities of the Trustee, and the Company's
obligations in connection therewith; and (iv) the Legal Defeasance provisions of
the Indenture. In addition, the Company may, at its option and at any time,
elect to have the obligations of the Company released with respect to certain
covenants that are described in the Indenture ("Covenant Defeasance") and
thereafter any omission to comply with such obligations shall not constitute a
Default or Event of Default with respect to the New Notes. In the event Covenant
Defeasance occurs, certain events (not including non-payment, bankruptcy,
receivership, rehabilitation and insolvency events) described under "Events of
Default" will no longer constitute an Event of Default with respect to the New
Notes.
 
     In order to exercise either Legal Defeasance or Covenant Defeasance, (i)
the Company must irrevocably deposit with the Trustee, in trust, for the benefit
of the Holders of the New Notes, cash in U.S. dollars, non-callable Government
Securities, or a combination thereof, in such amounts as will be sufficient, in
the opinion of a nationally recognized firm of independent public accountants,
to pay the principal of, premium, if any, and interest and Liquidated Damages,
if any, on the outstanding New Notes on the stated maturity or on the applicable
redemption date, as the case may be, and the Company must specify whether the
New Notes are being defeased to maturity or to a particular redemption date;
(ii) in the case of Legal Defeasance, the Company shall have delivered to the
Trustee an opinion of counsel in the United States reasonably acceptable to the
Trustee confirming that (A) the Company has received from, or there has been
published by, the Internal Revenue Service a ruling or (B) since the date of the
Indenture, there has been a change in the applicable federal income tax law, in
either case to the effect that, and based thereon such opinion of counsel shall
confirm that, the Holders of the outstanding New Notes will not recognize
income, gain or loss for federal income tax purposes as a result of such Legal
Defeasance and will be subject to federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such Legal
Defeasance had not occurred; (iii) in the case of Covenant Defeasance, the
Company shall have delivered to the Trustee an opinion of counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders of the
outstanding New Notes will not recognize income, gain or loss for federal income
tax purposes as a result of such Covenant Defeasance and will be subject to
federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Covenant Defeasance had not occurred; (iv)
no Default or Event of Default shall have occurred and be continuing on the date
of such deposit (other than a Default or Event of Default resulting from the
borrowing of funds to be applied to such deposit) or insofar as Events of
Default from bankruptcy or insolvency events are concerned, at any time in the
period ending on the 91st day after the date of deposit; (v) such Legal
Defeasance or Covenant Defeasance will not result in a breach or violation of,
or constitute a default under any material agreement or instrument (other than
the Indenture) to which the Company or any of its Subsidiaries is a party or by
which the Company or any of its Subsidiaries is bound; (vi) the Company must
have delivered to the Trustee an opinion of counsel to the effect that, assuming
no intervening bankruptcy of the Company between the date of deposit and the
91st day following the deposit and assuming no Holder of New Notes is an insider
of the Company, after the 91st day following the deposit, the trust funds will
not be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally; (vii) the
Company must deliver to the Trustee an Officers' Certificate stating that the
deposit was not made by the Company with the intent of preferring the Holders of
New Notes over the other creditors of the Company with the intent of defeating,
hindering, delaying or defrauding creditors of the Company or others; and (viii)
the Company must deliver to the Trustee an Officers' Certificate and an opinion
of counsel, each stating that all conditions precedent provided for relating to
the Legal Defeasance or the Covenant Defeasance have been complied with.

  TRANSFER AND EXCHANGE
 
     A Holder may transfer or exchange New Notes in accordance with the
Indenture. The Registrar and the Trustee may require a Holder, among other
things, to furnish appropriate endorsements and transfer documents and the
Company may require a Holder to pay any taxes and fees required by law or
permitted by the Indenture. The Company is not required to transfer or exchange
any New Note selected for redemption. Also, the Company is not required to
transfer or exchange any New Note for a period of 15 days before a selection of
New Notes to be redeemed.
 
     The registered Holder of a New Note will be treated as the owner of it for
all purposes.
 
  AMENDMENT, SUPPLEMENT AND WAIVER
 
     Except as provided in the next two succeeding paragraphs, the Indenture or
the New Notes may be amended or supplemented with the consent of the Holders of
at least a majority in principal amount of the New Notes then outstanding
(including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, New Notes), and any existing default
or compliance with any provision of the Indenture or the New Notes may be waived
with the consent of the Holders of a majority in principal amount of the then
outstanding New Notes (including, without limitation, consents obtained in
connection with a purchase of, or tender offer or exchange offer for, New
Notes).
 
     Without the consent of each Holder affected, an amendment or waiver may not
(with respect to any New Notes held by a non-consenting Holder): (i) reduce the
principal amount of New Notes whose Holders must consent to an amendment,
supplement or waiver; (ii) reduce the principal of or change the fixed maturity
of any New Note or alter the provisions with respect to the redemption of the
New Notes (other than provisions relating to the covenants described above under
the caption "-- Repurchase at the Option of Holders"); (iii) reduce the rate of
or change the time for payment of interest on any New Note; (iv) waive a Default
or Event of Default in the payment of principal of or premium, if any, or
interest on the New Notes (except a rescission of acceleration of the New Notes
by the Holders of at least a majority in aggregate principal amount of the New
Notes and a waiver of the payment default that resulted from such acceleration);
(v) make any New Note payable in money other than that stated in the New Notes;
(vi) make any change in the provisions of the Indenture relating to waivers of
past Defaults or the rights of Holders of New Notes to receive payments of
principal of or premium, if any, or interest on the New Notes; (vii) waive a
redemption payment with respect to any New Note (other than a payment required
by one of the covenants described above under the caption "-- Repurchase at the
Option of Holders") or (viii) make any change in the foregoing amendment and
waiver provisions. In addition, any amendment to the provisions of Article 10 of
the Indenture (which relate to subordination) will require the consent of the
Holders of at least 66 2/3% in aggregate principal amount of the New Notes then
outstanding if such amendment would adversely affect the rights of Holders of
New Notes.
 
     Notwithstanding the foregoing, without the consent of any Holder of New
Notes, the Company and the Trustee may amend or supplement the Indenture or the
New Notes to cure any ambiguity, defect or inconsistency, to provide for
uncertificated New Notes in addition to or in place of certificated New Notes,
to provide for the assumption of the Company's or any Subsidiary Guarantor's
obligations to Holders of New Notes in the case of a merger or consolidation or
sale of all or substantially all of the Company's or such Subsidiary Guarantor's
assets, to make any change that would provide any additional rights or benefits
to the Holders of New Notes or that does not adversely affect the legal rights
under the Indenture of any such Holder, or to comply with requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the Trust Indenture Act.
 
  CONCERNING THE TRUSTEE
 
     The Indenture contains certain limitations on the rights of the Trustee,
should it become a creditor of the Company, to obtain payment of claims in
certain cases, or to realize on certain property received in respect of any such
claim as security or otherwise. The Trustee will be permitted to engage in other
transactions;
 
                                       83
<PAGE>   87
 
however, if it acquires any conflicting interest it must eliminate such conflict
within 90 days, apply to the Commission for permission to continue or resign.
 
     The Holders of a majority in principal amount of the then outstanding New
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 in case an Event of Default
shall occur (which shall not be cured), the Trustee will be required, in the
exercise of its power, to use the degree of care of a prudent man in the conduct
of his 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 New Notes, unless such Holder shall have offered to the
Trustee security and indemnity satisfactory to it against any loss, liability or
expense.
 
  ADDITIONAL INFORMATION
 
     Anyone who receives this Prospectus may obtain a copy of the Indenture and
Registration Rights Agreement without charge by writing to Oshkosh Truck
Corporation, 2307 Oregon Street, P.O. Box 2566 Oshkosh, Wisconsin 54903, Attn:
Chief Financial Officer.
 
  BOOK-ENTRY, DELIVERY AND FORM
 
     The New Notes initially being issued in exchange for the Notes will be
represented by one or more registered global notes without interest coupons
(collectively, the "Global New Notes"). Notwithstanding the foregoing, Notes
held in certificated form will be exchanged solely for New Notes in certificated
form as discussed below. Upon issuance, the Global New Notes will be deposited
with the Trustee, as custodian for The Depository Trust Company ("DTC"), in New
York, New York, and registered in the name of DTC or its nominee, for credit to
the accounts of DTC's Direct and Indirect Participants (as defined below).
Transfers of beneficial interests in any Global New Notes will be subject to the
applicable rules and procedures of DTC and its Direct or Indirect Participants,
which may change from time to time.
 
     The Global New Notes may be transferred, in whole and not in part, only to
another nominee of DTC or to a successor of DTC or its nominee in certain
limited circumstances. Beneficial interests in the Global New Notes may be
exchanged for New Notes in certificated form in certain limited circumstances.
See "-- Transfer of Interests in Global New Notes for Certificated Notes."
 
     Initially, the Trustee will act as Paying Agent and Registrar. The New
Notes may be presented for registration of transfer and exchange at the offices
of the Registrar.
 
Depositary Procedures
 
     DTC has advised the Company that DTC is a limited-purpose trust company
created to hold securities for its participating organizations (collectively,
the "Direct Participants") and to facilitate the clearance and settlement of
transactions in those securities between Direct Participants through electronic
book-entry changes in accounts of Participants. The Direct Participants include
securities brokers and dealers (including the Initial Purchaser), banks, trust
companies, clearing corporations and certain other organizations. Access to
DTC's system is also available to other entities that clear through or maintain
a direct or indirect, custodial relationship with a Direct Participant
(collectively, the "Indirect Participants").
 
     DTC has advised the Company that, pursuant to DTC's procedures, (i) upon
deposit of the Global New Notes, DTC will credit the accounts of the Direct
Participants designated by the Exchange Agent with portions of the principal
amount of the Global New Notes, and (ii) DTC will maintain records of the
ownership interests of such Direct Participants in the Global New Notes and the
transfer of ownership interests by and between Direct Participants. DTC will not
maintain records of the ownership interests of, or the transfer of ownership
interests by and between, Indirect Participants or other owners of beneficial
interests in the Global New Notes. Direct Participants and Indirect Participants
must maintain their own records of the ownership interests of, and the transfer
of ownership interests by and between, Indirect Participants and other owners of
beneficial interests in the Global New Notes.
 
                                       84
<PAGE>   88
 
     Investors in the Global New Notes may hold their interests therein directly
through DTC if they are Direct Participants in DTC or indirectly through
organizations that are Direct Participants in DTC. All ownership interests in
any Global New Notes are subject to the procedures and requirements of DTC.
 
     The laws of some states in the United States require that certain persons
take physical delivery in definitive, certificated form, of securities that they
own. This may limit or curtail the ability to transfer beneficial interests in a
Global New Note to such persons. Because DTC can act only on behalf of Direct
Participants, which in turn act on behalf of Indirect Participants and others,
the ability of a person having a beneficial interest in a Global New Note to
pledge such interest to persons or entities that are not Direct Participants in
DTC, or to otherwise take actions in respect of such interests, may be affected
by the lack of physical certificates evidencing such interests. For certain
other restrictions on the transferability of the Notes see "-- Transfers of
Interests in Global Notes for Certificated Notes."
 
     Except as described in "-- Transfers of Interests in Global New Notes for
Certificated New Notes," owners of beneficial interests in the Global New Notes
will not have New Notes registered in their names, will not receive physical
delivery of New Notes in certificated form and will not be considered the
registered owners or holders thereof under the Indenture for any purpose.
 
     Under the terms of the Indenture, the Company ,the Subsidiary Guarantors
and the Trustee will treat the persons in whose names the New Notes are
registered (including New Notes represented by Global New Notes) as the owners
thereof for the purpose of receiving payments and for any and all other purposes
whatsoever. Payments in respect of the principal, premium, Liquidated Damages,
if any, and interest on Global New Notes registered in the name of DTC or its
nominee will be payable by the Trustee to DTC or its nominee as the registered
holder under the Indenture. Consequently, neither the Company, the Trustee nor
any agent of the Company or the Trustee has or will have any responsibility or
liability for (i) any aspect of DTC's records or any Direct Participant's or
Indirect Participant's records relating to or payments made on account of
beneficial ownership interests in the Global New Notes or for maintaining,
supervising or reviewing any of DTC's records or any Direct Participant's or
Indirect Participant's records relating to the beneficial ownership interests in
any Global New Note or (ii) any other matter relating to the actions and
practices of DTC or any of its Direct Participants or Indirect Participants.
 
     DTC has advised the Company that its current payment practice (for payments
of principal, interest and the like) with respect to securities such as the New
Notes is to credit the accounts of the relevant Direct Participants with such
payment on the payment date in amounts proportionate to such Direct
Participant's respective ownership interests in the Global New Notes as shown on
DTC's records. Payments by Direct Participants and Indirect Participants to the
beneficial owners of the New Notes will be governed by standing instructions and
customary practices between them and will not be the responsibility of DTC, the
Trustee, the Company or the Subsidiary Guarantors. Neither the Company, the
Subsidiary Guarantors nor the Trustee will be liable for any delay by DTC or its
Direct Participants or Indirect Participants in identifying the beneficial
owners of the New Notes and the Company and the Trustee may conclusively rely on
and will be protected in relying on instructions from DTC or its nominee as the
registered owner of the New Notes for all purposes.
 
     The Global New Notes will trade in DTC's Same-Day Funds Settlement System
and, therefore, transfers between Direct Participants in DTC will be effected in
accordance with DTC's procedures, and will be settled in immediately available
funds. Transfers between Indirect Participants who hold an interest through a
Direct Participant will be effected in accordance with the procedures of such
Direct Participant but generally will settle in immediately available funds.
 
     DTC has advised the Company that it will take any action permitted to be
taken by a holder of New Notes only at the direction of one or more Direct
Participants to whose account interests in the Global New Notes are credited and
only in respect of such portion of the aggregate principal amount of the New
Notes to which such Direct Participant or Direct Participants has or have given
direction. However, if there is an Event of Default under the New Notes, DTC
reserves the right to exchange Global New Notes (without the direction of one or
more of its Direct Participants) for New Notes in certificated form, and to
distribute such certificated forms of New Notes to its Direct Participants. See
"-- Transfers of Interests in Global New Notes for Certificated New Notes."

     Although DTC has agreed to the foregoing procedures to facilitate transfers
of interests in the Global New Notes among Direct Participants, it is under no
obligation to perform or to continue to perform such procedures, and such
procedures may be discontinued at any time. None of the Company, the Subsidiary
Guarantors, the Initial Purchaser or the Trustee shall have any responsibility
for the performance by DTC or its respective Direct and Indirect Participants of
their respective obligations under the rules and procedures governing any of
their operations.
 
     The information in this section concerning DTC and its book-entry systems
has been obtained from sources that the Company believes to be reliable, but the
Company takes no responsibility for the accuracy thereof.
 
Transfers of Interests in Global New Notes for Certificated New Notes
 
     An entire Global New Note may be exchanged for definitive New Notes in
registered, certificated form without interest coupons ("Certificated New
Notes") if (i) DTC (x) notifies the Company that it is unwilling or unable to
continue as depositary for the Global New Notes and the Company thereupon fails
to appoint a successor depositary within 90 days or (y) has ceased to be a
clearing agency registered under the Exchange Act, (ii) the Company, at its
option, notifies the Trustee in writing that it elects to cause the issuance of
Certificated New Notes or (iii) there shall have occurred and be continuing a
Default or an Event of Default with respect to the New Notes. In any such case,
the Company will notify the Trustee in writing that, upon surrender by the
Direct and Indirect Participants of their interest in such Global New Note,
Certificated New Notes will be issued to each person that such Direct and
Indirect Participants and DTC identify as being the beneficial owner of the
related New Notes.
 
     Beneficial interests in Global New Notes held by any Direct or Indirect
Participant may be exchanged for Certificated Notes upon request to DTC, by such
Direct Participant (for itself or on behalf of an Indirect Participant), to the
Trustee in accordance with customary DTC procedures. Certificated New Notes
delivered in exchange for any beneficial interest in any Global New Note will be
registered in the names, and issued in any approved denominations, requested by
DTC on behalf of such Direct or Indirect Participants (in accordance with DTC's
customary procedures).
 
     Neither the Company, the Subsidiary Guarantor nor the Trustee will be
liable for any delay by the holder of any Global New Note or DTC in identifying
the beneficial owners of New Notes, and the Company and the Trustee may
conclusively rely on, and will be protected in relying on, instructions from the
holder of the Global New Note or DTC for all purposes.
 
Same Day Settlement and Payment
 
     The Indenture requires that payments in respect of the New Notes
represented by the Global New Notes (including principal, premium, if any,
interest and Liquidated Damages, if any) be made by wire transfer of immediately
available same day funds to the accounts specified by the holder of such Global
New Note. With respect to Certificated New Notes, the Company will make all
payments of principal, premium, if any, interest and Liquidated Damages, if any,
by wire transfer of immediately available same day funds to the accounts
specified by the holders thereof or, if no such account is specified, by mailing
a check to each such holder's registered address. The Company expects that
secondary trading in the Certificated New Notes will also be settled in
immediately available funds.
 
  EXCHANGE OFFER; REGISTRATION RIGHTS
 
     The Company and the Initial Purchaser entered into the Registration Rights
Agreement on the Closing Date. Pursuant to the Registration Rights Agreement,
the Company agreed to file with the Commission the Exchange Offer Registration
Statement of which this Prospectus is a part on the appropriate form under the
Securities Act with respect to the New Notes. Pursuant to the Exchange Offer,
the Company is offering to the Holders of Transfer Restricted Securities who are
able to make certain representations the opportunity to exchange their Transfer
Restricted Securities for New Notes. If any Holder of Transfer Restricted
Securities notifies the Company prior to the 20th day following consummation of
the Exchange Offer that (A) it is
                                       86
<PAGE>   90
 
prohibited by law or Commission policy from participating in the Exchange Offer
or (B) that it may not resell the New Notes acquired by it in the Exchange Offer
to the public without delivering a prospectus and the prospectus contained in
the Exchange Offer Registration Statement is not appropriate or available for
such resales or (C) that it is a broker-dealer and owns Notes acquired directly
from the Company or an affiliate of the Company, the Company will file with the
Commission a Shelf Registration Statement to cover resales of the Notes by the
Holders thereof who satisfy certain conditions relating to the provision of
information in connection with the Shelf Registration Statement. The Company
will use its best efforts to cause the applicable registration statement to be
declared effective as promptly as possible by the Commission. For purposes of
the foregoing, "Transfer Restricted Securities" means each Note until: (i) the
date on which such Note has been exchanged by a person other than a
broker-dealer for a New Note in the Exchange Offer; (ii) following the exchange
by a broker-dealer in the Exchange Offer of a Note for a New Note, the date on
which such New Note is sold to a purchaser who receives from such broker-dealer
on or prior to the date of such sale a copy of the prospectus contained in the
Exchange Offer Registration Statement; (iii) the date on which such Note has
been effectively registered under the Securities Act and disposed of in
accordance with the Shelf Registration Statement; or (iv) the date on which such
Note is distributed to the public pursuant to Rule 144 under the Act.
 
     The Registration Rights Agreement provides, among other things, that: (i)
unless the Exchange Offer would not be permitted by applicable law or Commission
policy, the Company will commence the Exchange Offer and use its best efforts to
issue on or prior to 30 business days after the date on which the Exchange Offer
Registration Statement was declared effective by the Commission, New Notes in
exchange for all Notes tendered prior thereto in the Exchange Offer and (ii) if
obligated to file the Shelf Registration Statement, the Company will use its
best efforts to file the Shelf Registration Statement with the Commission on or
prior to 60 days after such filing obligation arises and to cause the Shelf
Registration to be declared effective by the Commission on or prior to 150 days
after such obligation arises. If (a) the Company fails to file any of the
Registration Statements required by the Registration Rights Agreement on or
before the date specified for such filing, (b) any of such Registration
Statements is not declared effective by the Commission on or prior to the date
specified for such effectiveness (the "Effectiveness Target Date"), or (c) the
Company fails to consummate the Exchange Offer within 30 business days of the
Effectiveness Target Date with respect to the Exchange Offer Registration
Statement, or (d) the Shelf Registration Statement or the Exchange Offer
Registration Statement is declared effective but thereafter ceases to be
effective or usable in connection with resales of Transfer Restricted Securities
during the periods specified in the Registration Rights Agreement (each such
event referred to in clauses (a) through (d) above a "Registration Default"),
then the Company will pay Liquidated Damages to each Holder of Notes, with
respect to the first 90-day period immediately following the occurrence of the
first Registration Default in an amount equal to $.05 per week per $1,000
principal amount of Notes held by such Holder. The amount of the Liquidated
Damages will increase by an additional $.05 per week per $1,000 principal amount
of Notes with respect to each subsequent 90-day period until all Registration
Defaults have been cured, up to a maximum amount of Liquidated Damages for all
Registration Defaults of $.25 per week per $1,000 principal amount of Notes. All
accrued Liquidated Damages will be paid by the Company on each Damages Payment
Date to the Global Note Holder by wire transfer of immediately available funds
or by federal funds check and to Holders of Certificated Notes by wire transfer
to the accounts specified by them or by mailing checks to their registered
addresses if no such accounts have been specified. Following the cure of all
Registration Defaults, the accrual of Liquidated Damages will cease.
 
     Holders of Notes will be required to make certain representations to the
Company (as described in the Registration Rights Agreement) in order to
participate in the Exchange Offer and will be required to deliver certain
information to be used in connection with the Shelf Registration Statement and
to provide comments on the Shelf Registration Statement within the time periods
set forth in the Registration Rights Agreement in order to have their Notes
included in the Shelf Registration Statement and benefit from the provisions
regarding Liquidated Damages set forth above.

obligation or otherwise, or redeemable at the option of the Holder thereof, in
whole or in part, on or prior to the date that is 91 days after the date on
which the Notes mature; provided, however, that any Capital Stock that would
constitute Disqualified Stock solely because the holders thereof have the right
to require the Company to repurchase such Capital Stock upon the occurrence of a

the terms of such Capital Stock provide that the Company may not repurchase or
redeem any such Capital Stock pursuant to such provisions unless such repurchase
or redemption complies with the covenant described above under the caption
"-- Certain Covenants -- Restricted Payments."
 
     "Equity Interests" means Capital Stock and all warrants, options or other

dividend payments, whether or not in cash, on any series of preferred stock of
such Person or any of its Restricted Subsidiaries, other than dividend payments

Company, times (b) a fraction, the numerator of which is one and the denominator
of which is one minus the then current combined federal, state and local
statutory tax rate of such Person, expressed as a decimal, in each case, on a

     "Fixed Charge Coverage Ratio" means with respect to any Person for any
period, the ratio of the Consolidated Cash Flow of such Person and its

redeems any Indebtedness (other than revolving credit or floor plan borrowings)
or issues or redeems preferred stock subsequent to the commencement of the
period for which the Fixed Charge Coverage Ratio is being calculated but prior
to the date on which the event for which the calculation of the Fixed Charge
Coverage Ratio is made (the "Calculation Date"), then the Fixed Charge Coverage
Ratio shall be calculated giving pro forma effect to such incurrence,
assumption, Guarantee or redemption of Indebtedness, or such issuance or
redemption of preferred stock, as if the same had occurred at the beginning of
the applicable four-quarter reference period. In addition, for purposes of
making the computation referred to above (i) acquisitions that have been made by
the Company or any of its Subsidiaries, including through mergers or

clause (iii) of the proviso set forth in the definition of Consolidated Net
Income and (y) to include the pro forma adjustments reflected in the unaudited
pro forma condensed consolidated financial statements prepared in connection
with the acquisition of McNeilus Companies, Inc. and included in this Prospectus

and (ii) the Consolidated Cash Flow attributable to discontinued operations, as
determined in accordance with GAAP, and operations or businesses disposed of
prior to the Calculation Date, shall be excluded, and (iii) the Fixed Charges
attributable to discontinued operations, as determined in accordance with GAAP,
and operations or businesses disposed of prior to the Calculation Date, shall be
excluded, but only to the extent that the obligations giving rise to such Fixed
Charges will not be obligations of the referent Person or any of its Restricted
Subsidiaries following the Calculation Date.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     THIS SUMMARY IS NOT INTENDED TO BE, NOR SHOULD IT BE CONSTRUED AS BEING,
LEGAL OR TAX ADVICE FOR OR TO ANY PARTICULAR PURCHASER, AND NO REPRESENTATION
WITH RESPECT TO THE CONSEQUENCES TO ANY PARTICULAR PURCHASER OF THE NEW NOTES IS
MADE. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN TAX ADVISERS WITH RESPECT
TO THEIR PARTICULAR CIRCUMSTANCES.
 
     The following discussion is a summary of certain United States federal
income tax considerations relevant to the purchase, ownership and disposition of
the New Notes by holders thereof, based upon current provisions of the Internal
Revenue Code of 1986, as amended (the "Code"), judicial decisions, and
administrative interpretations, all of which are subject to change at any time
by legislative, judicial or administrative action. Any such changes may be
applied retroactively in a manner that could adversely affect a holder of the
New Notes. There can be no assurance that the Internal Revenue Service (the
"IRS") will not challenge the conclusions stated below, and no ruling from the
IRS has been or will be sought on any of the matters discussed below.
 
     The following discussion does not purport to be a complete analysis of all
the potential federal income tax effects relating to the purchase, ownership and
disposition of the New Notes, and, without limiting the generality of the
foregoing, this summary does not address the effect of any special rules
applicable to certain types of purchasers (including dealers in securities,
insurance companies, financial institutions, tax-exempt entities, and persons
who hold New Notes as part of a straddle, hedge, or conversion transaction). In
addition, this discussion is limited to holders who are the initial purchasers
of the New Notes and hold the New Notes as capital assets within the meaning of
Section 1221 of the Code. This discussion does not address the effect of any
state, local, or foreign tax laws.
 
CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES TO U.S. PERSONS
 
     The term "U.S. Person" means (i) an individual who is a citizen or resident
of the United States, (ii) a corporation or partnership created or organized in
or under the laws of the United States or any state thereof, (iii) an estate the
income of which is subject to United States federal income taxation regardless
of its source, or (iv) a trust if a court within the United States is able to
exercise primary supervision over the administration of the trust and one or
more United States persons have the authority to control all substantial
decisions of the trust. The term "Foreign Person" means a person other than a
U.S. Person.
 
  Exchange Offer
 
     The issuance of the New Notes to Holders of the Notes pursuant to the terms
set forth in this Prospectus should not constitute an exchange for federal
income tax purposes. Consequently, no gain or loss should be recognized by
Holders of the Notes upon receipt of the New Notes, and ownership of the New
Notes should be considered a continuation of ownership of the Notes. For
purposes of determining gain or loss upon the subsequent sale or exchange of the
New Notes, a Holder's basis in the New Notes should be the same as such Holder's
basis in the Notes exchanged therefor. A Holder's holding period for the New
Notes should include the Holder's holding period for the Notes exchanged
therefor. The issue price, and other tax characteristics of the New Notes should
be identical to the issue price, and other tax characteristics of the Notes
exchanged therefor.
 
  Taxation of Interest and Liquidated Damages
 
     Any interest or Liquidated Damages earned on a New Note held by a U.S.
Person is generally required to be included in the holder's gross income for
federal income tax purposes at the time that the interest or Liquidated Damages
is paid or accrued, in accordance with the holder's method of accounting for
federal income tax purposes.
 
     For purposes of determining whether the New Notes are issued with original
issue discount, the Company has made a determination (which is binding on the
holders of the New Notes unless a holder explicitly discloses on its timely
filed federal income tax return that its determination in this regard is
different
                                       99
<PAGE>   103
 
from the Company's determination) that the possibility that any Liquidated
Damages will be paid on the New Notes is remote. Accordingly, the Company will
treat the New Notes as being issued without any original issue discount.
 
  Sale or Exchange of Notes
 
     In the case of a sale or exchange (including a redemption) of a New Note,
the holder will recognize gain or loss equal to the difference, if any, between
the amount received (other than any amount representing accrued but unpaid
stated interest) and the holder's adjusted tax basis in the New Note. Any such
gain or loss will be treated as a capital gain or loss. Any capital gain or loss
on a sale or exchange of a New Note will be treated as a long-term capital gain
or loss if, at the time of the sale or exchange, the New Note has been held by
the holder for more than one year; otherwise, the capital gain or loss will be
short-term. An individual's long-term capital gain is subject to federal income
tax at a maximum stated rate of either 20%, if the individual has held the New
Notes for more than 18 months prior to the sale or exchange, or 28%, if the
individual has held the New Notes for not more than 18 months prior to the sale
or exchange. An individual's short-term capital gain is taxed at ordinary income
tax rates. An individual's capital loss is first deductible against other
capital gains and then the amount of any remaining capital loss, up to $3,000
(or $1,500 for married persons filing separately), is deductible against other
income. Capital losses in excess of these amounts will carry over as a capital
loss to succeeding years.
 
     In addition, the recognition of capital gain on the New Notes could cause
an individual to exceed certain income thresholds which, in turn, could cause
items of income otherwise not taxable to the individual to become taxable and/or
could affect the individual's ability to utilize all or a portion of his or her
personal exemptions, certain itemized deductions and certain other deductions.
 
     For corporations, a capital gain is subject to federal income tax at a
stated maximum rate of 35%, while any capital loss can be offset only against
capital gains. Any unutilized capital loss generally can be carried back three
years and forward five years to be offset against net capital gains generated in
those years.
 
CERTAIN U.S. FEDERAL INCOME AND ESTATE TAX CONSEQUENCES TO FOREIGN PERSONS
 
     The following is a general discussion of certain United States federal
income and estate tax consequences of the ownership and disposition of New Notes
by a Foreign Person. This discussion is limited to Foreign Persons other than
former United States citizens described in Section 877(a) of the Code or former
residents of the United States described in Sections 877(e) or 7701(b)(10) of
the Code. Holders of New Notes who are Foreign Persons are urged to consult
their own tax advisers regarding the specific tax consequences to them of owning
and disposing of New Notes.
 
     Any interest or Liquidated Damages earned on a New Note by a holder who is
a Foreign Person will be considered "portfolio interest" and will not be subject
to United States federal income tax or withholding if:
 
          (1) such Foreign Person is neither (i) a "controlled foreign
     corporation" that is related to the Issuer as described in Section
     881(c)(3)(C) of the Code, (ii) a bank that has purchased New Notes pursuant
     to an extension of credit made in the ordinary course of its trade or
     business, nor (iii) a person who owns, directly or under the attribution
     rules of Section 871(h)(3)(C) of the Code, 10% or more of the voting power
     in the Company;
 
          (2) the person who would otherwise be required to withhold tax from
     payments of such interest or Liquidated Damages (the "withholding agent")
     is furnished an IRS Form W-9 (or equivalent), signed under penalties of
     perjury, identifying the beneficial owner of the Note and stating that the
     beneficial owner of the New Note is a Foreign Person; and
 
          (3) the interest or Liquidated Damages is not effectively connected
     with the conduct of a trade or business within the United States by the
     Foreign Person.
 
     The United States Treasury Department recently promulgated final
regulations regarding withholding and information reporting, which regulations
are generally effective for payments made after December 31,
 
                                       100
<PAGE>   104
 
1998. In general, the final regulations do not significantly alter the
substantive withholding and information reporting requirements but unify current
certification procedures and forms and clarify reliance standards. Special rules
apply which permit the shifting of primary responsibility for withholding to
certain financial intermediaries acting on behalf of beneficial owners. In the
case of interest paid to a foreign partnership (other than a partnership that
has entered into a withholding agreement with the IRS), the final regulations
specify that the "portfolio interest" exemption will not apply unless the
withholding agent receives appropriate certifications from the partners in
addition to receiving certain certifications from the partnership. A look-
through rule applies in the case of tiered partnerships.
 
     Any interest or Liquidated Damages (other than "portfolio interest") earned
on a New Note by a Foreign Person will be subject to United States federal
income tax and withholding at a rate of 30% (or at a lower rate under an
applicable tax treaty) if this interest or Liquidated Damages is not effectively
connected with the conduct of a trade or business within the United States by
this Foreign Person.
 
     Any interest or Liquidated Damages earned on a New Note, and any gain
realized on a sale or exchange (including a redemption) of a New Note, that is
effectively connected with the conduct of a trade or business within the United
States by a Foreign Person will be subject to United States federal income tax
at regular graduated rates (and, if the Foreign Person is a corporation, may
also be subject to a United States branch profits tax). Such income will not be
subject to United States income tax withholding, however, if the Foreign Person
furnishes the proper certificate to the withholding agent.
 
     Any gain realized by a Foreign Person on a sale or exchange (including a
redemption) of a New Note will not be subject to United States federal income
tax or withholding if (i) the gain is not effectively connected with the conduct
of a trade or business within the United States by the Foreign Person; and (ii)
in the case of a Foreign Person who is an individual, such individual is not
present in the United States for 183 days or more in the taxable year of the
sale or exchange, or the individual does not have a "tax home" in the United
States and the gain is not attributable to an office or other fixed place of
business maintained in the United States by the individual.
 
     Any New Notes owned by an individual who is not a citizen or resident (as
specially defined for United States federal estate tax purposes) of the United
States at the date of death will be included in such individual's estate for
United States federal estate tax purposes, unless all of the interest on such
New Notes constitutes "portfolio interest" (without regard to whether the
"portfolio interest" certification requirements are met), or unless an
applicable tax treaty provides otherwise.
 
BACKUP WITHHOLDING AND INFORMATION REPORTING
 
     A U.S. Person who holds New Notes will generally be subject to information
reporting and to backup withholding at a 31% rate with respect to interest on
the New Notes, and with respect to proceeds received on the sale or exchange of
New Notes through a broker. Information reporting and backup withholding will
generally not apply, however, with respect to payments made to certain exempt
recipients, such as corporations. In addition, backup withholding will generally
not apply to a U.S. Person who provides a taxpayer identification number and who
certifies, under penalties of perjury, that such number is correct and that the
holder has not been notified by the IRS that it is subject to backup withholding
for failure to report interest and dividend payments. Generally, such
certification is made on Form W-9.
 
     Information reporting on IRS Form 1099 and backup withholding will not
apply to payments made by the Company or any agent thereof to a holder of a New
Note if the holder has furnished a certification under penalties of perjury that
it is a Foreign Person, or has otherwise demonstrated that it qualifies for an
applicable exemption, provided that neither the Company nor such agent has
actual knowledge to the contrary. The interest and any Liquidated Damages earned
by a Foreign Person with respect to a New Note will generally be reported,
however, by the Company on IRS Form 1042S.
 
     If a Foreign Person sells a New Note through a United States office of a
broker, the broker is required to file an information report and is required to
withhold 31% of the sale proceeds unless the Foreign Person certifies under
penalties of perjury its non-United States status (and the broker does not have
actual
 
                                       101
<PAGE>   105
 
knowledge to the contrary) or otherwise establishes an exemption. If a Foreign
Person sells a New Note through a foreign office of a broker, backup withholding
is not required; but information reporting is required if the broker does not
have documentary evidence that the holder is a Foreign Person and if (i) the
broker is a U.S. Person, (ii) the broker is a "controlled foreign corporation"
(as defined in Section 957 of the Code), (iii) the broker derives 50% or more of
its gross income for a specified three year period from the conduct of a trade
or business in the United States, or (iv) in the case of payments made after
December 31, 1998, the broker is a foreign partnership with certain connections
to the United States.
 
     Any amount withheld from payment to a holder under the backup withholding
rules will generally be allowed as a credit against such holder's United States
federal income tax liability, if any, and may entitle such holder to a refund,
provided that the required information is furnished to the IRS.
 
                                       102
<PAGE>   106
 
                              PLAN OF DISTRIBUTION
 
     Each broker-dealer that receives New Notes for its own account (a
"Participating Broker-Dealer") pursuant to the Exchange Offer must acknowledge
that it will deliver a Prospectus in connection with the initial sales of such
New Notes. This Prospectus, as it may be amended or supplemented from time to
time, may be used by a Participating Broker-Dealer in connection with the sales
of New Notes received in exchange for Notes where such Notes were acquired as
the result of market-making activities or other trading activities. The Company
will make this Prospectus, as amended or supplemented, available to any
Participating Broker-Dealer for use in connection with any such resale and
Participating Broker-Dealers shall be authorized to deliver this Prospectus for
the period specified in the Registration Rights Agreement.
 
     The Company will not receive any proceeds from any sales of the New Notes
by Participating Broker-Dealers. New Notes received by Participating
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 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 at 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 Participating Broker-Dealer that resells the New Notes
that were received by it for its own account pursuant to the Exchange Offer. Any
broker or dealer that participates in a distribution of such New Notes may be
deemed to be an "underwriter" within the meaning of the Securities Act and may
profit on any such resale of New 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 that
it will deliver and by delivering a Prospectus, a Participating Broker-Dealer
will not be deemed to admit that it is an "underwriter" within the meaning of
the Securities Act.
 
     The Initial Purchaser and certain of its affiliates have, from time to
time, performed certain banking, financial advisory and investment banking
services for the Company and certain of its affiliates, for which they have
received customary fees and expenses. A portion of the net proceeds from the
Note Offering was used to repay outstanding indebtedness under the Existing Bank
Credit Agreement of which Bank of America, an affiliate of BancAmerica Robertson
Stephens, is a lender. Bank of America is the lead agent and a lender under the
Senior Credit Facility, for which it receives customary fees and expenses.
BALCAP, an affiliate of BancAmerica Robertson Stephens, is a partner with the
Leasing Partner under the Lease Financing Facility.
 
                                 LEGAL MATTERS
 
     The validity of the New Notes offered hereby will be passed upon on behalf
of the Company by Foley & Lardner, Milwaukee, Wisconsin, legal advisors to the
Company. Michael W. Grebe, a partner in the firm of Foley & Lardner, is a
director of the Company.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Board of Directors
Oshkosh Truck Corporation
 
We have audited the accompanying consolidated balance sheets of Oshkosh Truck
Corporation (the Company) as of September 30, 1997 and 1996, and the related
consolidated statements of income (loss), shareholders' equity and cash flows
for each of the three years in the period ended September 30, 1997. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
In our opinion, the financial statements referred to above present fairly, in
all material respects, the consolidated financial position of the Company at
September 30, 1997 and 1996, and the consolidated results of its operations and
its cash flows for each of the three years in the period ended September 30,
1997, in conformity with generally accepted accounting principles.

                           OSHKOSH TRUCK CORPORATION
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
              SEPTEMBER 30, 1997 AND DECEMBER 31, 1997 (UNAUDITED)
               (IN THOUSANDS, EXCEPT SHARE AND PER SHARE AMOUNTS)
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     OPERATIONS -- Oshkosh Truck Corporation and its wholly-owned subsidiaries
(the company) is a leading manufacturer of a wide variety of heavy duty
specialized trucks. The company sells its products into three principal markets
- -- fire and emergency support, defense, and other commercial truck markets. The
company's fire and emergency support business is principally conducted through
its wholly-owned subsidiary, Pierce Manufacturing Inc. (Pierce).
 
     PRINCIPLES OF CONSOLIDATION AND PRESENTATION -- The consolidated financial
statements include the accounts of Oshkosh Truck Corporation and all its
wholly-owned subsidiaries and are prepared in conformity with U.S. generally
accepted accounting principles. The preparation of 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 and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
All significant intercompany accounts and transactions have been eliminated.
 
     CASH AND CASH EQUIVALENTS -- The company considers all highly liquid
investments with a maturity of three months or less when purchased to be cash
equivalents. Cash equivalents, consisting principally of commercial paper,
totaled $23,022 at September 30, 1997. The cost of these securities, which are
considered "available for sale" for financial reporting purposes, approximates
fair value at September 30, 1997, and December 31, 1997.
 
     INVENTORIES -- The company values its inventories at the lower of cost,
computed principally on the last-in, first-out (LIFO) method, or market.
 
     PROPERTY, PLANT AND EQUIPMENT -- Property, plant and equipment are recorded
at cost. Depreciation is provided over the estimated useful lives of the
respective assets principally on accelerated methods.
 
     DEFERRED CHARGES -- Deferred charges include certain engineering and
technical support costs incurred in connection with multi-year government
contracts. These costs are charged to cost of sales when the related project is
billable to the government, or are amortized to cost of sales as base units are
delivered under the related contracts.
 
     OTHER LONG-TERM ASSETS -- Other long-term assets include capitalized
software and related costs which are amortized on a straight-line method over a
three to five year period, deferred financing costs which are amortized to
interest expense over the term of the debt, prepaid funding of pension costs and
certain investments. During fiscal 1996, the company wrote off its $3,025 equity
investment in a Mexican bus manufacturer due to prolonged weakness in the
Mexican economy and continuing high losses and high leverage reported by the
Mexican affiliate. Also, in fiscal 1996, the company wrote off a $200 equity
investment in Steeltech Manufacturing, Inc. (Steeltech) and a $900 investment in
a joint venture which leases equipment to Steeltech (see Note 11).
 
     GOODWILL AND OTHER INTANGIBLE ASSETS -- The cost of goodwill and other
intangible assets is amortized on a straight-line basis over the estimated
periods benefitted ranging from 13 to 40 years.
 
     IMPAIRMENT OF LONG-LIVED ASSETS -- Property, plant and equipment, other
long-term assets and goodwill and other intangible assets are reviewed for
impairment whenever events or changes in circumstances indicate that the
carrying amount may not be recoverable. If the sum of the expected undiscounted
cash flows is less than the carrying value of the related asset or group of
assets, a loss is recognized for the difference between the fair value and
carrying value of the asset or group of assets. Such analyses necessarily
involve significant judgment.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     CUSTOMER ADVANCES -- Customer advances principally represent amounts
received in advance of the completion of a fire apparatus vehicle. Certain of
these advances bear interest at variable rates approximating the prime rate.
 
     REVENUE RECOGNITION -- Sales under fixed-price defense contracts are
recorded as units are accepted by the government. Change orders are not invoiced
until agreed upon by the government. Recognition of profit on change orders and
on contracts which do not involve fixed prices is based upon estimates which may
be revised during the terms of the contracts. Sales to commercial customers are
recorded when the goods or services are billable at time of shipment or delivery
of the trucks.
 
     RESEARCH AND DEVELOPMENT -- Research and development costs are charged to
expense as incurred and amounted to approximately $7,847, $6,304, and $5,443 for
continuing operations during fiscal 1997, 1996, and 1995, respectively.
 
     WARRANTY -- Provisions for estimated warranty and other related costs are
recorded at the time of sale and are periodically adjusted to reflect actual
experience. Amounts expensed with respect to continuing operations in fiscal
1997, 1996, and 1995 were $9,658, $7,741, and $4,518, respectively.
 
     INCOME TAXES -- Deferred income taxes are provided to recognize temporary
differences between the financial reporting basis and the income tax basis of
the company's assets and liabilities using currently enacted tax rates and laws.
 
     FAIR VALUES -- The carrying amounts of receivables, accounts payable and
long-term debt approximated fair value as of September 30, 1997 and 1996.
 
     ENVIRONMENTAL REMEDIATION COSTS -- Statement of Position 96-1
"Environmental Remediation Liabilities" (SOP 96-1) became effective for the
company in fiscal 1997. In accordance with SOP 96-1, the company accrues for
losses associated with environmental remediation obligations when such losses
are probable and reasonably estimable. Costs of future expenditures for
environmental remediation obligations are not discounted to their present value.
Recoveries of environmental remediation costs from other parties are recorded as
assets when their receipt is deemed probable. The accruals are adjusted as
further information develops or circumstances change.
 
     EARNINGS (LOSS) PER SHARE -- In February 1997, the Financial Accounting
Standards Board issued Statement of Financial Accounting Standards (SFAS) No.
128, "Earnings per Share". SFAS No. 128 replaced the calculation of primary and
fully diluted earnings per share with basic and diluted earnings per share.
Unlike primary earnings per share, basic earnings per share excludes any
dilutive effects of options, warrants and convertible securities. Earnings per
share amounts for all periods have been presented and, where appropriate,
restated to conform to SFAS No. 128 requirements.
 
     The following table sets forth the computation of basis and diluted
weighted average shares used in the per share calculations:

     NEW ACCOUNTING STANDARDS -- In June 1997, the Financial Accounting
Standards Board issued SFAS No. 130, "Reporting Comprehensive Income." SFAS No.
130 establishes the standards for reporting and displaying comprehensive income
and its components (revenues, expenses, gains, and losses) as part of a full set
of financial statements. This statement requires that all elements of
comprehensive income be reported in a

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
financial statement that is displayed with the same prominence as other
financial statements. The statement is effective for fiscal years beginning
after December 15, 1997. Since this statement applies only to the presentation
of comprehensive income, it will not have any impact on the company's results of
operations, financial position or cash flows.
 
     In June 1997, the Financial Accounting Standards Board also issued SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information." SFAS
No. 131 establishes the standards for the manner in which public enterprises are
required to report financial and descriptive information about their operating
segments. The statement defines operating segments as components of an
enterprise for which separate financial information is available and evaluated
regularly as a means for assessing segment performance and allocating resources
to segments. A measure of profit or loss, total assets and other related
information are required to be disclosed for each operating segment. In
addition, this statement requires the annual disclosure of information
concerning revenues derived from the enterprise's products or services,
countries in which it earns revenue or holds assets, and major customers. The
statement is also effective for fiscal years beginning after December 15, 1997.
The adoption of SFAS No. 131 will not affect the company's results of operations
or financial position, but will affect the disclosure of segment information.

     The increase in goodwill from fiscal 1996 to fiscal 1997 is due to
finalization of purchase accounting related to the Pierce acquisition.
 
     The company engaged third party business valuation appraisers to determine
the fair value of the distribution network in connection with its acquisition of
Pierce (see Note 3). The company believes Pierce maintains the largest North
American fire apparatus distribution network and has exclusive contracts with
each distributor related to the fire apparatus product offerings manufactured by
Pierce. To establish the useful life of the distribution network, a historical
turnover analysis was performed.
 
3. ACQUISITIONS
 
     On September 18, 1996, the company acquired for cash all of the issued and
outstanding stock of Pierce, a leading manufacturer and marketer of fire trucks
and other fire apparatus in the U.S. The acquisition price of $156,926,
including acquisition costs and net of cash acquired, was financed from
borrowings under a bank credit facility (see Note 4).
 
     The acquisition was accounted for using the purchase method of accounting
and, accordingly, the operating results of Pierce are included in the company's
consolidated statements of income (loss) since the date of acquisition. The
purchase price, including acquisition costs, was allocated based on the
estimated fair values of the assets acquired and liabilities assumed at the date
of the acquisition and was subsequently adjusted during fiscal 1997.
Approximately $62,000 of the purchase price was allocated to the distribution
network and other intangible assets. The excess of the purchase price over the
estimated fair value of net assets acquired amounted to $103,887 which has been
accounted for as goodwill.
 
     Pro forma unaudited consolidated operating results of the company, assuming
Pierce had been acquired as of October 1, 1995 and 1994, are summarized below:

all such adjustments. Anticipated efficiencies from the consolidation of
Pierce's manufacturing facilities and from the synergies related to the
consolidation of certain functions among Pierce and the company were not fully
determinable and therefore have been excluded from the amounts included in the
pro forma operating results. These pro forma results do not purport to be
indicative of the results of operations which would have resulted had the
combination been in effect as of October 1, 1995 and 1994 or of the future
results of operations of the consolidated entities.
 
     On November 9, 1995, the company through its wholly-owned subsidiary,
Summit Performance Systems, Inc. (Summit), acquired the land, buildings,
machinery and equipment, and technology of Friesz Manufacturing Company (Friesz)
from available cash for $3,912. Friesz was engaged in the manufacture and sale
of concrete mixer systems and related aftermarket replacements parts.
Approximately $2,150 of the purchase price has been allocated to intangible
assets, principally designs and related technology. The acquisition was
accounted for using the purchase method of accounting and, accordingly, the
operating results of Friesz are included in the company's consolidated
statements of income (loss) since the date of acquisition. Had the acquisition
occurred as of October 1, 1995 or 1994, there would have been no material pro
forma effects on the net sales, net income (loss) or earnings (loss) per share
of the company in fiscal 1996 or 1995.
 
4. LONG-TERM DEBT
 
     On September 18, 1996, the company entered into a bank credit agreement
(the Bank Credit Agreement) to finance the acquisition of Pierce (see Note 3)
and to refinance a previous revolving credit facility. The Bank Credit Agreement
consists of a $150,000 term loan which requires annual principal payments of
$15,000 through fiscal 2002 and a final payment of $60,000 on September 30,
2003, and a $50,000 revolving credit facility for working capital purposes which
expires on September 30, 1999. The total of all term loan and revolving credit
facility borrowings, excluding letters of credit, must be reduced to or below
$145,000, and $130,000 for 60 consecutive days in fiscal 1998 and 1999,
respectively.
 
     Interest on the term loan and the revolving credit facility is payable at
prime or at the applicable Eurodollar rate plus 2.25% and 1.875%, respectively,
subject to adjustment if certain financial criteria are met (weighted-average
rate of 7.98% and zero, respectively, at September 30, 1997, 8.25% and 8.25%,
respectively, at September 30, 1996, and 7.72% and 8.5%, respectively, at
December 31, 1997).
 
     The company is charged a 0.25% fee with respect to any unused balance under
its revolving credit facility, and a 1.875% fee with respect to any letters of
credit issued under the revolving credit facility. These fees are subject to
adjustment if certain financial criteria are met. At September 30, 1997, $2,962
of standby letters of credit reduced available capacity under the revolving
credit facility to $47,038.
 
     At September 30, 1997, substantially all the tangible and intangible assets
of the company are pledged as collateral under the Bank Credit Agreement. Among
other restrictions, the Bank Credit Agreement: (1) limits payments of dividends,
purchases of the company's stock, and capital expenditures; (2) requires that
certain financial ratios be maintained at prescribed levels; (3) restricts the
ability of the company to make additional borrowings, or to consolidate, merge
or otherwise fundamentally change the ownership of the company; and (4) limits
investments, dispositions of assets and guarantees of indebtedness. The company
believes that such limitations should not impair its future operating
activities.
 
     The aggregate annual maturities of long-term debt for the five years
succeeding September 30, 1997, are as follows: 1998 -- $15,000; 1999 -- $15,000;
2,000 -- $15,000; 2001 -- $15,000; and 2002 -- $15,000.
 
     From October 1, 1997 through December 8, 1997, the company paid from
available cash the $15,000 mandatory principal payment due September 30, 1998
and paid an additional $25,000 on the term loan which will be applied on a pro
rata basis to the principal payments due in the fiscal years 1999 to 2003.

6. EMPLOYEE BENEFIT PLANS
 
     The company has defined benefit pension plans covering substantially all
employees. The plans provide benefits based on compensation, years of service
and date of birth. The company's policy is to fund the plans in amounts which
comply with contribution limits imposed by law.
 
     Components of net periodic pension cost for these plans for fiscal 1997,
1996, and 1995, including costs of discontinued operations which are not
significant in any year presented but excluding Pierce pension costs for 1996
due to the proximity of its acquisition to the company's fiscal year end, are as
follows:

allow for an orderly transition of Class A Common Stock into Common Stock. The
agreement provides that at the time of death or incapacity of the survivor of

Articles of Incorporation which will provide for a mandatory conversion of all
Class A Common Stock into Common Stock.

Class A Common Stock are entitled to elect the remaining directors (subject to
any rights granted to any series of Preferred Stock) and are entitled to one
vote per share for the election of directors and on all matters presented to the
shareholders for vote.
 
     The Common Stock shareholders are entitled to receive a liquidation
preference of $7.50 per share before any payment or distribution to holders of
the Class A Common Stock. Thereafter, holders of the Class A Common Stock are
entitled to receive $7.50 per share before any further payment or distribution

     SFAS No. 123, "Accounting for Stock-Based Compensation", became effective
for the company in fiscal 1997. As allowed by SFAS 123, the company has elected
to continue to follow Accounting Principles Board Opinion (APB) No. 25,
"Accounting for Stock Issued to Employees" in accounting for the Plan. Under APB
No. 25, the company does not recognize compensation expense on the issuance of
its stock options because the option terms are fixed and the exercise price
equals the market price of the underlying stock on the grant date.
 
     As required by SFAS 123, the company has determined the pro forma
information as if the company had accounted for stock options granted since
September 30, 1995 under the fair value method of SFAS 123. The Black-Scholes
option pricing model was used with the following weighted-average assumptions:
risk-free interest rates of 6.27% in 1997 and 5.39% and 6.38% in 1996; dividend
yield of 4.17% in 1997 and 3.60% and 3.28% in 1996; expected common stock market
price volatility factor of .305; and a weighted-average expected life of the
options of six years. The weighted-average fair value of options granted in 1997
and 1996 was $3.07 and $4.08 per share, respectively. The pro forma effect of
these options on net earnings and earnings per share was not material. These pro
forma calculations only include the effects of 1996 and 1997 grants. As such,
the impacts are not necessarily indicative of the effects on reported net income
of future years.

9. OPERATING LEASES
 
     Total rental expense for plant and equipment charged to continuing
operations under noncancelable operating leases was $886, $797, and $1,004 in
fiscal 1997, 1996, and 1995, respectively. Minimum rental payments due under
operating leases for subsequent fiscal years are: 1998 -- $937; 1999 -- $545;
2000 -- $212; 2001 -- $123; and 2002 -- $71.
 
     Included in rental expense are charges of $128, $128, and $215 in fiscal
1997, 1996, and 1995, respectively, relating to leases between the company and
certain shareholders.
 
10. DISCONTINUED OPERATIONS
 
     On June 2, 1995, Freightliner acquired certain assets of the company's
motor home, bus and van chassis business. The consideration included cash of
$23,815 and the assumption by Freightliner of certain liabilities. The assets
sold to Freightliner consisted of inventories, property, plant and equipment and
the company's ownership interest in a Mexican chassis manufacturer. The
liabilities assumed by Freightliner included certain warranty obligations
related to previously produced chassis in excess of certain specified amounts
for which the company retained liability and industrial revenue bonds that were
secured by the underlying real estate. The disposition of chassis business has
been accounted for as a discontinued operation. Revenues of the chassis business
for fiscal 1995 (through the date of sale) were $55,804. The net liabilities of
the discontinued operations have been segregated in the consolidated balance
sheets. Details of such amounts are as follows:

     In fiscal 1996, the company incurred charges totaling $2,623 arising from
the write-off of receivables and other obligations related to the company's
former joint venture in Mexico. In addition, in fiscal 1996, the company
recognized additional warranty and other related costs totaling $2,063 with
respect to the company's former U.S. chassis business.
 
     The company has allocated interest on the debt which was assumed by
Freightliner to discontinued operations. Interest expense included in
discontinued operations totaled $685 in fiscal 1995.
 
11. CONTINGENCIES, SIGNIFICANT ESTIMATES AND CONCENTRATIONS
 
     The company is engaged in litigation against Super Steel Products
Corporation (SSPC), the company's former supplier of mixer systems for front
discharge concrete mixer trucks under a long-term supply contract. SSPC sued the
company in state court claiming that the company breached the contract. The
company counterclaimed for repudiation of contract. On July 26, 1996, a jury
returned a verdict for SSPC awarding damages totaling $4,485. On October 10,
1996, the state court judge overturned the verdict against the company, granted
judgment for the company on its counterclaim, and ordered a new trial for
damages on the company's counterclaim. Both SSPC and the company have appealed
the state court judge's decision. The Wisconsin Court of Appeals has agreed to
hear the case and both the company and SSPC have filed briefs in this matter.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The company currently is engaged in the arbitration of certain disputes
between the Oshkosh Florida Division and O.V. Containers, Inc., which arose out
of the performance of a contract to deliver 690 skeletal container chassis. The
arbitration is being conducted before a three-member panel under the commercial
dispute rules of the American Arbitration Association, and is not expected to
conclude before April 1998. The company is vigorously contesting warranty and
other claims made against it, and has asserted substantial claims against O.V.
Containers, Inc. The outcome of these matters cannot be predicted at the present
time.
 
     As part of its routine business operations, the company disposes of and
recycles or reclaims certain industrial waste materials, chemicals and solvents
at third party disposal and recycling facilities which are licensed by
appropriate governmental agencies. In some instances, these facilities have been
and may be designated by the United States Environmental Protection Agency (EPA)
or a state environmental agency for remediation. Under the Comprehensive
Environmental Response, Compensation, and Liability Act (the Superfund law) and
similar state laws, each potentially responsible party (PRP) that contributed
hazardous substances may be jointly and severally liable for the costs
associated with cleaning up the site. Typically, PRPs negotiate a resolution
with the EPA and/or the state environmental agencies. PRPs also negotiate with
each other regarding allocation of the cleanup cost.
 
     As to one such Superfund site, Pierce is one of 414 PRPs participating in
the costs of addressing the site and has been assigned an allocation share of
approximately 0.04%. Currently a remedial investigation/ feasibility study is
being completed, and as such, an estimate for the total cost of the remediation
of this site has not been made to date. However, based on estimates and the
assigned allocations, the company believes its liability at the site will not be
material and its share is adequately covered through reserves established by the
company at September 30, 1997. Actual liability could vary based on results of
the study, the resources of other PRPs, and the company's final share of
liability.
 
     The company is addressing a regional trichloroethylene (TCE) groundwater
plume on the south side of Oshkosh, Wisconsin. The company believes there may be
multiple sources in the area. TCE was detected at the company's North Plant
facility with recent testing showing the highest concentrations in a monitoring
well located on the upgradient property line. Because the investigation process
is still ongoing, it is not possible for the company to estimate its long-term
total liability associated with this issue at this time. Also, as part of the
regional TCE groundwater investigation, the company conducted a groundwater
investigation of a former landfill located on company property. The landfill,
acquired by the company in 1972, is approximately 2.0 acres in size and is
believed to have been used for the disposal of household waste. Based on the
investigation, the company does not believe the landfill is one of the sources
of the TCE contamination. Based upon current knowledge, the company believes its
liability associated with the TCE issue will not be material and is adequately
covered through reserves established by the company at September 30, 1997.
However, this may change as investigations proceed by the company, other
unrelated property owners, and government.
 
     The company is subject to other environmental matters and legal proceedings
and claims which arise in the ordinary course of business. Although the final
results of all such matters and claims cannot be predicted with certainty,
management believes that the ultimate resolution of all such matters and claims,
after taking into account the liabilities accrued with respect to such matters
and claims, will not have a material adverse effect on the company's financial
condition or results of operations. Actual results could vary, among other
things, due to the uncertainties involved in litigation.
 
     The company has guaranteed certain customers' obligations under deferred
payment contracts and lease purchase agreements totaling approximately $4,178 at
September 30, 1997. The company is also contingently liable under bid,
performance and specialty bonds totaling approximately $94,101 at September 30,
1997.
 
     Provisions for estimated warranty and other related costs are recorded at
the time of sale and are periodically adjusted to reflect actual experience. As
of September 30, 1997 and 1996, the company has accrued $12,320 and $8,942 for
warranty claims. Certain warranty and other related claims involve matters of

dispute that ultimately are resolved by negotiation, arbitration or litigation.
Infrequently, a material warranty issue can arise which is beyond the scope of
the company's historical experience. During fiscal 1997 and 1996, the company
recorded warranty and other related costs for matters beyond the company's
historical experience totaling $3,770 and $5,602, respectively, with respect to
continuing operations and $2,063 with respect to discontinued operations in
fiscal 1996 (see Note 10). The additional charges in fiscal 1997 and 1996 with
regard to continuing operations principally related to the dispute with O.V.
Containers Inc., and secondarily to repair certain matters related to refuse and
front-discharge chassis. The additional warranty charges with respect to
discontinued operations in fiscal 1996 resulted from the underestimation of the
warranty liabilities retained by the company upon the sale of the company's
former chassis business. It is reasonably possible that additional warranty and
other related claims could arise from disputes or other matters beyond the scope
of the company's historical experience.
 
     The company subcontracted production under an $85,000 ISO-Compatible
Palletized Flatracks (IPF) contract for the U.S. Army to Steeltech, a
minority-owned firm, pursuant to Department of Defense regulations under the IPF
contract. Due to financial difficulties encountered by Steeltech, the company
advanced working capital requirements to Steeltech in fiscal 1995 and 1996. As a
result of delays in the start-up of full-scale production under the IPF
contract, the company wrote off certain of its advances and an investment in
Steeltech totaling $3,300 in fiscal 1996. Such charges were determined based on
the amount of advances that were deemed to be unrealizable based on a projection
of Steeltech's cash flows through completion of the IPF contract. Steeltech's
IPF production passed first article testing in July 1996 and production is
expected to be completed in fiscal 1998. As of September 30, 1997 and 1996, the
company had outstanding advances due from Steeltech of $162 and $2,855,
respectively. In fiscal 1996, the company also wrote off an investment of $900
in a joint venture which leases equipment to Steeltech and accrued $1,084 for
the potential satisfaction of a guarantee of 50% of the outstanding indebtedness
of the joint venture. Such charges were based on a projection of Steeltech's
cash flows which indicated that Steeltech could not sustain its lease payments
to the joint venture, and because the company believed that there was not a
market for the sale of the leased equipment. The company is further contingently
liable for Department of Defense progress payments that have been advanced to
Steeltech totaling $3,352 at September 30, 1997 ($5,380 at September 30, 1996)
in the event of incomplete performance under the IPF contract. While management
currently expects the company to realize its remaining advances to Steeltech as
of September 30, 1997 and to avoid liability for progress payments advanced to
Steeltech, it is reasonably possible that the company could become liable for a
portion of such progress payments.
 
     The company derives a significant portion of its revenue from the U.S.
Department of Defense, as follows:

     Inherent in doing business with the U.S. Department of Defense are certain
risks, including technological changes and changes in levels of defense
spending. All U.S. Department of Defense contracts contain a provision that they
may be terminated at any time at the convenience of the government. In such an
event, the company is entitled to recover allowable costs plus a reasonable
profit earned to the date of termination.
 
     Various actions or claims have been asserted or may be asserted in the
future by the government against the company. A potential action by the
government against the company in connection with a grand jury investigation was
commenced in 1989. In 1996, the government discontinued this investigation
without any action against the company or its employees, although a civil
investigation is possible.

13. SUBSEQUENT EVENT
 
     On December 8, 1997, the company agreed to acquire McNeilus Companies, Inc.
(McNeilus), a $300.0 million manufacturer and marketer of refuse and recycling
truck bodies, rear-discharge concrete mixers, and ready-mix batch plants. The
total purchase cost for all McNeilus stock and related non-compete and ancillary
agreements is $250.0 million in cash and will be financed through the issuance
of $100.0 million Senior Subordinated Notes and a $325.0 million senior debt
facility inclusive of a $100.0 million revolver and term loans of $100.0
million, $62.5 million and $62.5 million with terms of six, seven and eight
years, respectively.
 
     The transaction is expected to close in the first quarter of calendar 1998.
Under certain conditions, if the acquisition is not consummated, the company may
be required to pay McNeilus a fee of $10.0 million, and conversely, McNeilus may
be required to pay a $10.0 million fee to the company.
 
     Pierce and Summit, wholly owned subsidiaries of the company, will fully,
unconditionally, jointly and severally guarantee the company's obligations under
the Senior Subordinated Notes. The following is

                          INDEPENDENT AUDITOR'S REPORT
 
Board of Directors
McNeilus Companies, Inc.
 
     We have audited the accompanying consolidated balance sheets of McNeilus
Companies, Inc. and Subsidiaries, as of February 28, 1997 and February 29, 1996,
and the related consolidated statements of income, stockholders' equity and cash
flows for each of the three years in the period ended February 28, 1997. These
consolidated financial statements are the responsibility of the Companies'
management. Our responsibility is to express an opinion on these consolidated
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 consolidated financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the consolidated financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
consolidated financial statement presentation. We believe that our audits
provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of McNeilus
Companies, Inc. and Subsidiaries as of February 28, 1997 and February 29, 1996,
and the results of their operations and their cash flows for each of the three
years in the period ended February 28, 1997, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
           FOR THE THREE YEARS ENDED FEBRUARY 28, 1997 (IN THOUSANDS)
      (INFORMATION PERTAINING TO NOVEMBER 30, 1997 AND 1996 IS UNAUDITED)
 
NOTE 1  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
Principles of Consolidation
 
     The consolidated financial statements include the accounts of McNeilus
Companies, Inc. and its wholly-owned subsidiaries (the Companies).
 
     All significant intercompany transactions and accounts of the companies
included in these consolidated financial statements have been eliminated.
 
Lines of Business
 
     McNeilus Truck and Manufacturing, Inc., a wholly-owned subsidiary of
McNeilus Companies, Inc. manufactures products used primarily by the ready-mix
and refuse industries in the United States and abroad. McNeilus Truck and
Manufacturing, Inc. has entered into a marketing agreement with its wholly-owned
subsidiary, McNeilus Financial, Inc., to sell and market its products. Under
this agreement, McNeilus Financial, Inc. makes all final destination sales and
provides branch facility services.
 
     Leases of manufactured equipment are made through McNeilus Financial
Services, Inc., a wholly-owned subsidiary of McNeilus Companies, Inc.
Substantially all leases have an initial term of five years, and are accounted
for as sales-type leases. Unearned finance income is recognized over the life of
the leases in decreasing amounts which produce a constant rate of return on the
unrecovered investment in the leases.
 
     McIntire Fabricators, Inc., Iowa Contract Fabricators, Inc. and Kensett
Fabricators, Inc., all wholly-owned subsidiaries of McNeilus Companies, Inc.,
provide component fabrication services to McNeilus Truck and Manufacturing, Inc.
 
     The Companies insure for automobile, workers' compensation and employer's
liability, and general liability risks through Nation's Casualty Insurance,
Inc., a wholly-owned subsidiary. Nation's Casualty Insurance, Inc. insures only
for members of the McNeilus group of companies. Aggregate and excess losses are
subject to outside insurance coverages. For the fiscal years ended 1997, 1996,
1995 and the nine months ended November 30, 1997 and 1996 expenses incurred,
before income taxes, included in the consolidated statements of income was
approximately $2,484, $1,695, $1,815, $1,668 and $1,754, respectively.
 
Use of Estimates
 
     The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions. Actual results may vary from those estimates. Areas impacted
through this process include the allowance for doubtful accounts and leases
receivable, residual values of leased equipment, current and long-term
classification of notes receivable and payable, useful lives of property and
equipment, accrued warranty and insurance reserves, and income taxes.
 
Cash and Cash Equivalents
 
     Cash and cash equivalents include cash in checking and savings accounts.
 
Accounts and Leases Receivable
 
     Accounts receivable are reflected net of an allowance for doubtful accounts
of $177, $341 and $172 as of February 28, 1997, February 29, 1996 and November
30, 1997, respectively. The Companies also use the reserve method in accounting
for doubtful leases. Net investment in sales-type leases are reflected net of an

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
allowance for doubtful leases of $0, $0 and $20 as of February 28, 1997,
February 29, 1996 and November 30, 1997, respectively.
 
Lease Accounting Policies
 
     Leasing activities consist of the leasing of ready mix equipment and plants
and refuse equipment. For financial reporting, these leases are accounted for as
sales-type leases, with profit on the sale recognized at lease inception. Cost
consists of the equipment's book value, less the present value of its residual.
The present value of both the future minimum lease payments and the residual
value are recorded as assets.
 
     Residual values, representing the estimated net present value of the
equipment at the termination of the lease, are recorded at the inception of the
lease based on amounts estimated by management based upon its experience and
judgment.
 
     Unearned income is the amount by which total rentals and estimated residual
value of equipment exceeds the cost of the equipment. Unearned income is
amortized over the lease term so as to produce a constant periodic rate of
return on the net investment in the lease.
 
Short-Term Investments
 
     Short-term investments consist of deposits which are restricted through
statutory or trust agreements for the insurance operations of Nations Casualty
Insurance, Inc. These deposits consist primarily of certificates of deposit,
stated at cost, which mature within one year, as well as deposits in a
non-interest bearing account.
 
Inventories
 
     The Companies utilize the LIFO (last-in, first-out) method of pricing
inventories for truck chassis, manufactured mixers, ready-mix plants,
replacement drums, and replacement parts. All other inventory is stated at FIFO
(first-in, first-out) cost.
 
Revenue Recognition
 
     Sales are recorded when the goods or services are billable at time of
shipment or delivery.
 
Depreciation
 
     Depreciation is provided for financial reporting by annual charges to
income calculated by use of the straight-line, 150% declining balance and 200%
declining balance methods to amortize the cost of depreciable assets over their
estimated useful lives. Depreciation is provided based upon the following useful
lives:

Buildings...................................................    10-35 years
Shop and Office Equipment...................................     3-10 years
Transportation Equipment....................................      3-7 years
</TABLE>
 
     Depreciation deducted in tax returns differs from depreciation for
financial reporting purposes due to the use of accelerated methods for tax
versus straight-line for financial reporting on certain assets.
 
Product Warranty
 
     The Companies use the reserve method in accounting for warranty costs. A
warranty reserve of approximately $1,400 is recorded as of February 28, 1997 and
February 29, 1996 and November 30, 1997, respectively. For the fiscal years
ended 1997, 1996 and 1995 and the nine months ended November 30, 1997 and 1996
amounts expensed included in the consolidated statements of income were
approximately $1,189, $2,427, $2,209, $170 and $1,157, respectively.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
Deferred Income Taxes
 
     Deferred income taxes are provided on temporary differences between
financial reporting and income tax reporting of certain income and expense
items, as well as the accounting for the leasing activities of McNeilus
Financial Services, Inc. as sales-type leases for financial reporting and
operating leases for income tax reporting.
 
Advertising Costs
 
     Advertising costs are expensed when incurred. For the fiscal years ended
1997, 1996 and 1995 and the nine months ended November 30, 1997 and 1996
advertising expense was approximately $1,458, $822, $694, $701 and $1,165,
respectively.
 
Pension and Profit Sharing Plans
 
     The Companies offer to its employees a qualified salary reduction
retirement plan under Sec. 401(k)of the Internal Revenue Code. The members of
the consolidated group provide a limited matching of contributions as an
incentive for employees to participate in the plan. For the fiscal years ended
1997, 1996 and 1995 and the nine months ended November 30, 1997 and 1996
contribution expense included in the consolidated statements of income was
approximately $278, $303, $289, $248 and $171, respectively.
 
Research and Development Costs
 
     Research and development costs are expensed when incurred. For the fiscal
years ended 1997, 1996 and 1995 and the nine months ended November 30, 1997 and
1996 research and development costs charged to expense were approximately $667,
$985, $607, $313 and $338, respectively.
 
New Accounting Standards
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards (SFAS) No. 128, "Earnings Per Share," which is
required to be adopted effective for both interim and annual financial
statements for periods ending after December 15, 1997. Among other provisions,
the dilutive effect of stock options must be excluded under the new requirements
for calculating basic earnings per share, which will replace primary earnings
per share. This change will not impact the Companies' earnings per share
calculations.
 
     In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 establishes the standards for
reporting and displaying comprehensive income and its components (revenues,
expenses, gains, and losses) as part of a full set of financial statements. This
statement requires that all elements of comprehensive income be reported in a
financial statement that is displayed with the same prominence as other
financial statements. The statement is effective for fiscal years beginning
after December 15, 1997. Since this statement applies only to the presentation
of comprehensive income, it will not have any impact on the Companies' results
of operations, financial position or cash flows.
 
     In June 1997, the Financial Accounting Standards Board also issued SFAS No.
131, "Disclosures about Segments of an Enterprise and Related Information," SFAS
No. 131 establishes the standards for the manner in which public enterprises are
required to report financial and descriptive information about their operating
segments. The statement defines operating segments as components of an
enterprise for which separate financial information is available and evaluated
regularly as a means for assessing segment performance and allocating resources
to segments. A measure of profit or loss, total assets, and other related
information are required to be disclosed for each operating segment. In
addition, this statement requires the annual disclosure of information
concerning revenues derived from the enterprise's products or services,
countries in which it earns revenue or holds assets, and major customers. The
statement is also effective for fiscal years beginning
                                      F-29

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
after December 15, 1997. The adoption of SFAS No. 131 will not affect the
Companies' results of operations or financial position, but will affect the
disclosure of segment information.
 
Reclassification of Financial Statement Data
 
     Investments in Unconsolidated Subsidiaries, and the earnings from those
subsidiaries, presented as a separate line in the 1996 and 1995 balance sheets
and income statements have been reclassified to discontinued operation lines
within those statements to conform with their presentation in the 1997 financial
statements.
 
NOTE 2  DISCONTINUED OPERATIONS
 
     In December, 1997 the Company entered into an agreement with a minority
stockholder to sell its 92% interest in ready mix operations, Ready Mix Holding,
Inc. and Subsidiaries. The sale price, which will be determined by independent
appraisal, has yet to be determined.
 
     In December, 1997 the Company entered into an agreement with a minority
stockholder to sell its wholly-owned credit life insurance subsidiary, McNeilus
Fidelity Life Insurance Company. The sale price, which will be determined by
independent appraisal, has yet to be determined.
 
     In December, 1997 the Company entered into an agreement with an unrelated
party to sell its wholly-owned subsidiary, Sterling Travel of Austin, Inc., for
$300.
 
     The disposals of these companies are being accounted for as discontinued
operations. Net assets of these companies at February 28, 1997, February 29,
1996 and November 30, 1997 are summarized as follows:

NOTE 10  INCOME TAX MATTERS
 
     McNeilus Companies, Inc. and its subsidiaries file a consolidated federal
income tax return. The consolidated federal tax liability is initially allocated
to the members of the consolidated group based on the "taxable income method."
If a member's separate incurred tax liability exceed the amount so allocated, an
additional allocation is made equal to 100 percent of the excess. The
corresponding reduction in tax liability is allocated proportionately to the
members whose losses or credits were used to decrease the tax liability of the
group.
 
     State tax expense is based on estimated state liabilities from filings made
under separate, combined, consolidated, or unitary filings as required by the
various taxing jurisdictions. McNeilus Truck and Manufacturing, Inc. reimburses
all other subsidiaries of McNeilus Companies, Inc. for excessive state tax
liabilities (in excess of 10% of taxable income) resulting from combined or
unitary filings.

        UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
 
     The unaudited pro forma condensed consolidated statements of income and
condensed consolidated balance sheet (collectively, the "Pro Forma Statements")
have been derived by the application of pro forma adjustments, which give effect
to the acquisition by Oshkosh Truck Corporation ("Oshkosh") of all of the issued
and outstanding common stock of McNeilus Companies, Inc. ("McNeilus") (the
"Acquisition"), the issuance by Oshkosh of $100 million Senior Subordinated
Notes (the "Offering"), the consummation of a $325 million Senior Credit
Facility ("Senior Credit Facility"), the prepayment of outstanding term loans
and borrowings under the revolving credit facility (the "Debt Repayment") and
the establishment of a lease financing partnership (the "Lease Financing")
(collectively referred to as the "Transactions") to the historical financial
statements of Oshkosh and McNeilus included elsewhere in this Prospectus as if
the Transactions had been consummated for balance sheet purposes as of December
31, 1997, and for statement of income purposes as of the beginning of the
periods presented. For purposes of the Pro Forma Statements, the Transactions
are assumed to have occurred simultaneously.
 
     THE PRO FORMA STATEMENTS DO NOT PURPORT TO REPRESENT WHAT OSHKOSH'S
FINANCIAL POSITION OR RESULTS OF OPERATIONS WOULD ACTUALLY HAVE BEEN HAD THE
TRANSACTIONS IN FACT OCCURRED ON THE ASSUMED DATES OR TO PROJECT OSHKOSH'S
FINANCIAL POSITION OR RESULTS OF OPERATIONS FOR ANY FUTURE DATE OR FUTURE
PERIOD. THE PRO FORMA STATEMENTS SHOULD BE READ IN CONJUNCTION WITH THE
HISTORICAL FINANCIAL STATEMENTS AND RELATED NOTES OF OSHKOSH AND MCNEILUS
INCLUDED ELSEWHERE IN THIS PROSPECTUS.
 
     The pro forma adjustments, as described in the accompanying notes to the
Pro Forma Statements, are based on available information and certain assumptions
that management believes are reasonable.
 
     The Acquisition has been accounted for under the purchase method of
accounting. The purchase price for McNeilus has been allocated to the tangible
and intangible assets and liabilities of McNeilus based on preliminary estimates
of their fair values. The allocation of the purchase price is subject to
revision when additional information concerning certain asset and liability
valuations is obtained. However, in management's opinion, no material
adjustments from the preliminary estimates to final amounts are expected.
 
     Oshkosh and McNeilus have different fiscal year ends -- September 30 for
Oshkosh and the last day of February for McNeilus -- and as a result, amounts
for McNeilus as of November 30, 1997 have been combined with amounts of Oshkosh
as of December 31, 1997 for the Unaudited Pro Forma Condensed Consolidated
Balance Sheet. The Unaudited Condensed Consolidated Statement of Income for
Oshkosh for the twelve month period ended September 30, 1997 and for the twelve
month period ended December 31, 1997 have been combined with the Unaudited
Condensed Consolidated Statement of Income for McNeilus for the twelve month
period ended November 30, 1997. The Unaudited Condensed Consolidated Statement
of Income of Oshkosh for the three months ended December 31, 1997 have been
combined with the Unaudited Condensed Consolidated Statement of Income for
McNeilus for the three months ended November 30, 1997. Statement of income
information of McNeilus for the three month period ended November 30, 1997 is
therefore included in both the interim and the annual Pro Forma Statements.
 
     The application of the pro forma adjustments to the historical results of
operations of Oshkosh for the twelve months ended December 31, 1997 and
September 30, 1997, results in the pro forma income from continuing operations
being greater than the historical income from continuing operations of Oshkosh.
Net sales of Oshkosh for the first quarter of each fiscal year (the three months
ended December 31) and net sales of McNeilus for the third quarter of each
fiscal year (the three months ended November 30) represent the lowest quarter of
shipments for each company during their respective fiscal years. Accordingly,
the application of the pro forma adjustments to the historical results of
operations of Oshkosh for the three months ended December 31, 1997, results in
the pro forma income from continuing operations being less than the historical
income from continuing operations of Oshkosh.

     (b) The Acquisition has been accounted for by Oshkosh using the purchase
method of accounting. The total purchase cost has been allocated first to the
assets and liabilities of McNeilus based upon their respective fair values with
the remainder allocated to costs in excess of net assets acquired. The
historical shareholders' equity of McNeilus has been eliminated. The aggregate
purchase cost and the preliminary allocation of the purchase cost to the assets
and liabilities of McNeilus are as follows:

(1) The allocation of the purchase cost reflects the revaluation of McNeilus'
    assets and liabilities to their estimated fair values based on preliminary
    estimates. The preliminary allocation may differ from the final allocation.
 
(2) In accordance with the Stock Purchase Agreement among Oshkosh, McNeilus and
    the shareholders of McNeilus, Ready Mix Holding, Inc. and Subsidiaries (a
    majority-owned subsidiary of McNeilus included in the historical financial
    statements of McNeilus as a discontinued operation) were sold in February
    1998 to a shareholder of McNeilus in exchange for a note receivable. In
    February 1998, the note receivable was distributed to the shareholders of
    McNeilus as a dividend.
 
     (c) Adjustment to reflect depreciation expense based on the new basis and
remaining economic useful lives of McNeilus property, plant and equipment. New
basis depreciation is computed using the straight line method over the remaining
useful lives.

    charge of approximately $755 which represents the write-off of unamortized
    debt issuance costs, net of income taxes associated with the Debt Repayment.

     (j) Adjustment to record the tax effect on the above adjustments using
Oshkosh's marginal effective income tax rate of 39%. All adjustments were
tax-effected except for goodwill amortization.
 
     (k) Included in historical and pro forma operating expense for McNeilus are
charitable contributions (including charitable contributions to national
organizations) of $1,109 and $284 for the twelve month and three month periods
ended November 30, 1997, respectively. While no pro forma reductions of these
expenses have been reflected in the pro forma statements of income, Oshkosh's
policy is to focus charitable contributions on needs of the communities in which
it operates. Management expects that annual charitable contribution levels for
the McNeilus entity would approximate $100.
