                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information and financial statements, including the notes thereto, appearing
elsewhere in this Prospectus. Unless the context otherwise requires, "Gradall"
or the "Company" refers to Gradall Industries, Inc., a Delaware corporation, and
its consolidated subsidiaries.
 
                                  THE COMPANY
 
     Gradall is a leading manufacturer of telescopic hydraulic excavators and
rough-terrain variable reach material handlers as well as related service parts.
The Company's products are marketed under the widely respected Gradall tradename
and are distinguished by their telescopic boom technology, versatility,
productivity and reliability. Gradall's telescopic booms, which are manufactured
from high-strength specialty steel, are unique both in their shape and
engineering design, which provide added strength with minimal weight, and, in
the case of excavators, in their ability to rotate a full 360 degrees. Gradall
products serve niche markets within the construction equipment industry and
typically command premium prices. In 1997, total sales were $158.7 million,
comprised of $57.4 million in sales of excavators, $84.0 million in sales of
material handlers and $17.3 million in sales of service parts. Since January
1993, the Company has introduced 14 new products which accounted for in excess
of 60% of Gradall's net sales in 1997.
 
     Gradall excavators are typically used by general contractors and government
agencies for ditching, sloping, finished grading, general maintenance and
infrastructure projects. The Company's excavators are sold through approximately
48 independent distributors at approximately 152 locations throughout North
America. The introduction and ongoing development of the Company's XL Series
excavators, featuring the unique Gradall rotating, telescopic booms with
high-pressure hydraulics, have allowed the Company to continue to dominate its
traditional niche market of wheeled, telescopic boom excavators and to
strengthen its competitive position in the larger market of conventional crawler
excavators, a market historically dominated by knuckle-boom technology.
 
     Gradall rough-terrain variable reach material handlers are typically used
by residential, non-residential and institutional building contractors for
lifting, transporting and placing a wide variety of materials at their point of
use or storage. The Company's material handlers are sold through approximately
44 independent distributors at approximately 127 locations throughout North
America. In addition, Gradall material handlers are available at national rental
companies at over 250 locations. The Company continues to introduce new material
handlers with Gradall's unique 90 degrees rear-pivot steering, hydrostatic drive
and low profile design which provide an exceptional combination of
maneuverability, versatility and stability.
 
   
     Gradall's strategy is to design and produce high quality hydraulic
excavators and material handlers for niche markets while simultaneously reducing
manufacturing costs and increasing production efficiencies. Gradall's ability to
design and customize each of its product lines to fit the specifications of its
customers augments the uniqueness of the Company's products. In 1995, the
Company commenced a multi-year program designed to expand plant capacity and
reduce production costs by improving labor efficiency, equipment productivity
and quality. The Company invested $4.2 million in 1995, $2.3 million in 1996 and
$5.3 million in 1997 for capital improvements pursuant to this program. During
1998, the Company plans to invest approximately $8.1 million for additional
capital improvements under this program. Management believes that these
strategies have enabled the Company to increase substantially its profitability
in recent years. In addition, the Board of Directors has approved in principle a
multi-year capacity expansion program (the "Capacity Expansion Program") which
is intended to raise capacity in excess of 50% over the next three to five
years. The Capacity Expansion Program will require a $30 to $50 million
investment over this time frame. The Company has entered into no commitments
with respect to the Capacity Expansion Program and may alter or revise the
Capacity Expansion Program based upon changes in market demand and/or economic
conditions. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."
    
 
     The Company's principal executive offices are located at 406 Mill Avenue
SW, New Philadelphia, OH 44663 and its telephone number is (330) 339-2211.

    care benefits liability reflecting a change in actuarial assumptions related
    to the projected growth in medical costs.
 
(2) An extraordinary item of $1.0 million, net of taxes, related to early
    extinguishment of senior and subordinated debt which was incurred in
    September 1996 to write off unamortized deferred financing costs and the

                                  RISK FACTORS
 
     Any investment in the shares of Common Stock offered hereby involves risk.
Prospective investors should consider carefully the following factors in
evaluating any investment in the Common Stock.
 
IMPACT OF SIGNIFICANT COMPETITION
 
     The markets in which the Company operates are highly competitive. The
Company faces competition in each of its product lines from a number of
different manufacturers, some of which have greater financial and other
resources than the Company. The principal competitive factors affecting the
markets for the Company's products include performance, functionality, price,
brand recognition, customer service and support, and product availability.
 
CYCLICALITY MAY LEAD TO FLUCTUATIONS IN DEMAND
 
     The Company markets its products primarily to the construction industry.
Accordingly, demand for the Company's products, and therefore the profitability
of the Company, are sensitive to the state of the U.S. economy in general,
regional economic conditions, and particularly to changes in private
construction spending and infrastructure spending funded by the public sector.
There can be no assurance that the cyclicality of any of these factors will not
have a material adverse effect on the Company's business, operations or
financial performance.
 
DEPENDENCE ON SUCCESSFUL PRODUCT DEVELOPMENT
 
     In excess of 60% of the Company's net sales in 1997 were attributable to
new products introduced since 1993. The Company believes that its future growth
and profitability are dependent on its continued development of new products and
the success of such new products, and no assurance can be given that the Company
will be able to successfully develop and distribute additional new products.
 
DEPENDENCE ON DISTRIBUTION NETWORK
 
     The Company primarily markets and distributes its products through a
network of independent distributors and believes that this network is a core
strength of its business. While it is not dependent on any single distributor,
loss of certain key distributors could have an adverse effect on the business,
operations and financial results of the Company. The Company has agreements with
its distributors under which the distributors purchase products from the Company
at agreed upon prices for resale within the distributor's territory. Although
the Company's distributors are not required to purchase any minimum number of
products, they are required to maintain agreed-upon inventory levels. In
addition to the Company's products, its distributors typically sell construction
equipment manufactured by third parties, including competitors of the Company.
See "Business -- Marketing & Distribution." The Company also sells its products
to national rental companies, who in turn rent the products to end-users. The
Company believes that this distribution channel is increasingly important to its
continued success, and the loss of certain key national rental company accounts
could have a material adverse effect on the business, operations and financial
results of the Company.
 
DEPENDENCE ON NEW PHILADELPHIA FACILITY
 
     Substantially all of the Company's operations are conducted from a single
company-owned facility in New Philadelphia, Ohio (the "New Philadelphia
Facility") which accommodates the Company's corporate offices, manufacturing and
assembly operations and certain warehouse space. The Company leases additional
warehouse space at a nearby location. Equipment failures at the New Philadelphia
Facility could limit or shut down the Company's production for a significant
period of time. In order to minimize the risk of equipment failure, the Company
follows a comprehensive maintenance and loss prevention program and periodically
reviews its failure exposure. To date, the Company has not experienced any
significant equipment failure. However, no assurance can be given that a
material shutdown will not occur in the future or that such a shutdown would not
have a material adverse effect on the business, operations and financial results
of the Company. In addition to equipment failure, the New Philadelphia Facility
also is subject to the risk of catastrophic loss. The Company maintains property
damage insurance which it believes to be adequate to provide for reconstruction
of damaged equipment, as well as business interruption insurance to mitigate
losses resulting from any production shutdown caused by an
 
                                        7
<PAGE>   9
 
insured loss. However, no assurance can be given that such insurance will be
adequate to cover losses which could occur.
 
   
CAPACITY CONSTRAINTS; CAPACITY EXPANSION PROGRAM
    
 
   
     Based on its current equipment and manufacturing processes, the New
Philadelphia Facility is operating at capacity. Significant increases in output
from current levels will require increases in capital expenditures and other
productivity improvements. In 1995, the Company commenced a multi-year program
designed to expand plant capacity and reduce production costs by improving labor
efficiency, equipment productivity and quality. The Company invested $4.2
million in 1995, $2.3 million in 1996 and $5.3 million in 1997 for capital
improvements pursuant to this program. During 1998, the Company plans to invest
approximately $8.1 million for capital improvements under this program. The
Company believes that recently completed capital expenditures, which have
expanded plant capacity, together with planned capital expenditures, should
allow the Company to meet anticipated demand for its products. In addition, the
Board of Directors has approved in principle the Capacity Expansion Program
which is intended to raise capacity in excess of 50% over the next three to five
years. The Capacity Expansion Program will require a $30 to $50 million
investment over this time frame. The Company has entered into no commitments
with respect to the Capacity Expansion Program and may alter or revise the
Capacity Expansion Program based upon changes in market demand and/or economic
conditions. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity And Capital Resources." However, there can be
no assurance that the Company will be successful in implementing these measures
or that such measures will be successful in increasing plant capacity or meeting
future increases in demand.
    
 
LABOR RELATIONS
 
   
     The Company's 461 hourly employees are represented by the International
Association of Machinists and Aerospace Workers ("IAM") and are currently
working under a three-year contract which will expire on April 16, 2000. The
Company's current contract with the IAM was approved after a three-week stoppage
which occurred when the union failed to ratify a proposed three-year contract.
During the three-week work stoppage the Company was able to continue production
and shipment, though at a reduced level. There can be no assurance that the
Company will be able to negotiate satisfactory contracts with the union in the
future or that the Company's union employees will not participate in any work
stoppage which could have a material adverse effect on the operations of the
Company.
    
 
DEPENDENCE ON KEY MANAGEMENT
 
     The success of the Company's business is dependent upon the management and
leadership skills of Barry L. Phillips, the Company's President and Chief
Executive Officer, and other members of the Company's senior management team.
Although the Company has an employment agreement with Mr. Phillips, the loss of
Mr. Phillips or any other member of the senior management team or an inability
to attract and retain additional personnel could have a material adverse effect
on the Company. There can be no assurance that the Company will be able to
retain its existing senior management personnel or to continue to attract
additional qualified personnel.
 
DEPENDENCE ON CERTAIN SUPPLIERS
 
     Certain of the components included in the Company's products are obtained
from a single supplier or a limited number of suppliers. Disruption or
termination of supplier relationships or the inability to obtain needed
quantities to meet the Company's output of product could have a material adverse
effect on the Company's operations. The Company believes that alternative
sources could be obtained, if necessary, but the inability to obtain sufficient
quantities of the components or the need to develop alternative sources, if and
as required in the future, could result in delays or reductions in product
shipments which in turn may have a material adverse effect on the Company's
operating results and customer relationships.
 
RISK OF CLAIMS FOR PRODUCT LIABILITY
 
     Due to the nature of its products, the Company may be subject to
significant claims for product liability. The Company is a party to various
lawsuits seeking damages for alleged product liability arising from the use of
its products. The Company currently maintains product liability insurance with
an annual aggregate limit of $6
                                        8
<PAGE>   10
 
million subject to a self-insurance retention in the amount of $225,000 per
claim. There can be no assurance that proceeds available under the Company's
insurance policy would be adequate to cover potential product liability claims.
A successful claim against the Company in excess of the Company's insurance
coverage could have a material adverse effect on the financial results of the
Company. The Company's product liability costs for any claim have not exceeded
its self-insurance retention amount during any of the last three fiscal years.
 
ENVIRONMENTAL MATTERS
 
     The Company is subject to various federal, state and local environmental
laws and regulations, including those governing discharges into the air and
water, as well as the handling and disposal of solid and hazardous wastes.
Pursuant to these laws and regulations, the Company may be required from time to
time to remediate environmental contamination associated with releases of
hazardous substances. In addition, the Company has made and will continue to
make capital and other expenditures to comply with such environmental laws and
regulations. Although the Company does not anticipate that expenditures to
comply with environmental laws and regulations, including costs of remediation,
will be material, there can be no assurance that the costs of complying with
such existing or future laws or regulations will not exceed current estimates.
 
CONTROL BY MLGA FUND II, L.P.
 
   
     Upon the consummation of the Offering, approximately 25.0% of the
outstanding Common Stock of the Company (approximately 24.3% if the
Underwriters' over-allotment option is exercised in full) will be owned by MLGA
Fund II, L.P. ("Fund II") and its affiliates. Accordingly, Fund II and its
affiliates will be able to exert significant influence over the Company and its
business and affairs, including the election of directors. See "Selling
Stockholder" and "Description of Capital Stock."
    
 
ANTITAKEOVER PROVISIONS
 
   
     The Company's Amended and Restated Certificate of Incorporation will
provide the Board of Directors the authority to issue up to 2,000,000 shares of
preferred stock in one or more series with such distinctive descriptions, rights
and preferences as the Board may provide. The Company has reserved 300,000
shares of Series B Participating Cumulative Series B Preferred Stock for
issuance in connection with the Rights Plan (as defined below). The issuance of
the preferred stock could adversely affect the voting power of the holders of
Common Stock and, accordingly, could make more difficult the acquisition of the
Company by means of a tender offer, a proxy contest or otherwise. The Company
also is subject to Section 203 of the Delaware General Corporation Law which
limits transactions between a publicly held company and "interested
stockholders" (generally, those stockholders who own 15% or more of the
company's outstanding stock and their affiliates and associates). This provision
of Delaware law may also have the effect of deterring certain potential
acquisitions of the Company.
    
 
   
     In addition, the Company adopted a Rights Plan (the "Rights Plan") on May
29, 1998. Under the Rights Plan, each holder of Common Stock at the close of
business on June 10, 1998 will receive a dividend of one right (a "Right") for
each share of Common Stock held. Each share of Common Stock issued after June
10, 1998 but prior to the earlier of May 29, 2008 and the Distribution Date
(defined below) will be issued with a Right attached thereto. The Rights are not
exercisable until the earlier of: (i) the tenth business day after public
announcement that a person has become the beneficial owner of 15% or more of the
Common Stock or (ii) the tenth business day after the date of commencement of a
tender or exchange offer which would result in such ownership, in each case,
subject to extension by a majority of the Board of Directors not affiliated with
the person making such an acquisition or offer (such date, the "Distribution
Date"). Once a person has acquired such ownership, the Rights would permit
holders of Common Stock, other than the acquiring person, to purchase additional
Common Stock at a 50% discount to its then-current market price, thus diluting
the ownership position of the acquiring person. The Plan excludes current
holders of 15% or more of the Common Stock and Morgan Lewis Githens & Ahn
("MLGA") and its affiliates, associates and direct transferees, from the
definition of "acquiring person." The Rights will expire on May 29, 2008, unless
earlier exchanged or redeemed. The Plan may have the effect of deterring certain
potential acquisitions of the Company. See "Description of Capital
Stock -- Rights Plan."

                                  THE COMPANY
 
     Gradall is a leading manufacturer of telescopic hydraulic excavators and
rough-terrain variable reach material handlers as well as related service parts.
The Company's products are marketed under the widely respected Gradall tradename
and are distinguished by their telescopic boom technology, versatility,
productivity and reliability. Gradall's telescopic booms, which are manufactured
from high-strength specialty steel, are unique both in their shape and
engineering design, which provide added strength with minimal weight, and, in
the case of excavators, in their ability to rotate a full 360 degrees. Gradall
products serve niche markets within the construction equipment industry and
typically command premium prices. In 1997, total sales were $158.7 million,
comprised of $57.4 million in sales of excavators, $84.0 million in sales of

                                USE OF PROCEEDS
 
   
     The net proceeds to the Company from this Offering, after deducting
underwriting discounts and commissions and expenses payable by the Company in
connection with this Offering, are estimated to be approximately $6.82 million
(or $11.06 million if the over-allotment option is exercised). The Company
intends to use such net proceeds for general corporate purposes, including the
Capacity Expansion Program, and to repay outstanding indebtedness of the Company
under its revolving credit facility, amounts under which, after such repayment,
would be available for general corporate purposes as well as the Capacity
Expansion Program. As of March 31, 1998, the average interest rate under the
revolving credit facility was 7.38%. The Company is not required to make any
principal repayments of the amount outstanding under such facility until August
31, 1999.
    
 
   
     The Company will not receive any of the proceeds from the sale of shares of
Common Stock by the Selling Stockholder in this Offering. See "Selling
Stockholder."

                                DIVIDEND POLICY
 
     The Company currently intends to retain its future earnings to finance the
growth and development of its business and therefore does not anticipate paying
cash dividends on the Common Stock for the foreseeable future. Any future
determinations to pay dividends will be at the discretion of the Board of
Directors and will be dependent upon the Company's financial condition, results
of operations, capital requirements and such other factors as the Board of
Directors deems relevant. The Company's revolving credit facility prohibits the
payment of any dividends on the Common Stock.

telescopic boom excavators and variable reach material handlers. Concurrent with
the formation of Gradall Industries, Inc., the Company hired a new management
team and embarked on a strategy to profit from its established tradename by
redesigning and improving both its excavator and material handler product lines
and by strengthening and expanding its distribution network.
 
     Gradall Industries operates in two segments of the construction equipment
market. Historically, the majority of the Company's revenues has been generated
by the sale of telescopic boom excavators and related parts, while sales of
rough-terrain variable reach material handlers and related parts accounted for
the balance of the revenues. Beginning in 1995, and continuing through 1996 and
1997, the Company's product mix shifted and sales of material handlers exceeded
sales of excavators. The growth of Gradall's material handler business reflects
the strong growth of the material handler market. Gradall's excavator business
has grown with the increased sales of the Company's XL Series of excavators and
the introduction of new products in new markets.
 
     The Company's consolidated net sales grew from $118.4 million in 1995 to
$158.7 million in 1997, an increase of $40.3 million or 15.8% per annum. This
increase is largely due to significant growth in the rough-terrain variable
reach material handler market and to the increasing penetration of the excavator
market by the Company's XL Series of excavators. Of the $40.3 million total
increase of net sales, $31.7 million or 78.7% reflects growth in the Company's
material handlers business (including related service parts), and $8.6 million
or 21.3% relates to the growth of its excavator business (including related
service parts).
 
   
     From 1995 to 1997, sales of material handlers grew from $52.9 million to
$84.0 million representing an increase of 26.0% per annum. This growth is due to
the overall growth in the market for material handlers and to an increase in
demand for the Company's material handlers. Over the same period, the
rough-terrain variable reach material handler market has grown at an overall
unit rate of 32% per annum. This dynamic industry growth is due to new
applications, increased rental demand and displacement of straight-mast
forklifts and small rough-terrain cranes.
    
 
     From 1995 to 1997, sales of excavators grew from $49.2 million to $57.4
million, representing an increase of 8.0% per annum. This growth is due to the
success of the Company's XL Series excavators which strengthened Gradall's
competitive position in the market for conventional crawler excavators.
Approximately 75% of excavator units sold by the Company in 1997 were XL Series
models. In May 1997, Gradall shipped its first production units of the new XL
2200 excavator in the 12-14 ton size class. The Company believes that this new
model is well-positioned to take advantage of growth in the niche market for
smaller, more versatile high-pressure excavators.
 
   
     The Company manufactures and markets service parts for its excavators and
material handlers. Sales of service parts grew from $14.8 million in 1995 to
$17.3 million in 1997, representing an increase of 8.1% per annum. Approximately
72% of service parts sales are related to the excavator product line.
    
 
     Net income was reduced by an extraordinary charge of $1.0 million, net of
taxes, in 1996 due to the write off of unamortized deferred financing costs and
the discount on subordinated debt resulting from the repayment of indebtedness
from the proceeds of the Company's initial public offering of common stock.
 
     Generally, the Company's sales are not subject to significant seasonal
variations; however, its sales and earnings tend to be somewhat lower in January
and February due to adverse weather conditions in northern climates.

THREE MONTHS ENDED MARCH 31, 1998 COMPARED TO THREE MONTHS ENDED MARCH 31, 1997
    
 
     Net Sales.  Net sales for the three months ended March 31, 1998, were $41.5
million, an increase of $5.6 million or 15.7% compared to $35.9 million for the
three months ended March 31, 1997. The increase in net sales was attributable to
a significant increase in unit volume of material handlers. The unit volume of
excavators decreased slightly in the first quarter of 1998 and service parts
sales were level with the same quarter of the prior year.
 
     Gross Profit.  Gross profit for the three months ended March 31, 1998, was
$9.6 million, an increase of $0.9 million or 10.8%, compared to $8.6 million for
the three months ended March 31, 1997. Gross profit as a percentage of net sales
decreased to 23.0% for the three months ended March 31, 1998, from 24.0% for the
three months ended March 31, 1997, primarily due to the training costs of newly
hired employees required to support the increased production schedule.
 
   
     Research and Development and Product Engineering Costs.  Research and
development and product engineering costs expense for the three months ended
March 31, 1998 was $1.1 million, an increase of $0.2 million or 17.8% compared
to $0.9 million for the three months ended March 31, 1997. This increase was due
to the addition of engineering personnel to support new product development.
Although research and development costs increased to support new product
development, the overall cost as a percent of net sales remained constant at
2.5%.
    
 
   
     Selling, General and Administrative Expenses.  Selling, general and
administrative expense ("SG&A") for the three months ended March 31, 1998, was
$3.3 million, an increase of $0.2 million or 7.0% compared to $3.0 million for
the three months ended March 31, 1997. This increase is attributable to higher
advertising spending and interest subsidy for a higher number of dealer floor
plan units. The total cost of SG&A when expressed as a percent of net sales
decreased to 7.9% for the first quarter of 1998 from 8.5% for the same period in
the prior year.
    
 
     Interest Expense.  Interest expense for the three months ended March 31,
1998 was $0.2 million, which was a slight decrease from the three months ended
March 31, 1997. This decrease in interest expense was due to lower average
borrowings in connection with working capital and capital expenditure needs. The
lower borrowings were slightly offset by a small increase in LIBOR rates.
 
     Income Tax Provision.  Income tax expense for the three months ended March
31, 1998 was $2.0 million, an increase of $0.3 million or 14.7%, compared to
$1.7 million for the three months ended March 31, 1997, and represents an
effective tax rate of 39.1% for both periods.
 
     Net Income.  Net income for the three months ended March 31, 1998 was $3.1
million, an increase of $0.4 million or 14.9% compared to $2.7 million for the
three months ended March 31, 1997. This increase was primarily attributable to
the increased sales volume of the material handler product.
 
     Earnings Per Common Share.  Basic and fully diluted earnings per common
share for the three months ended March 31, 1998 was $0.34, an increase of $0.04
per share or 13.3% compared to $0.30 per share for the three months ended March
31, 1997.
 
   
FISCAL 1997 COMPARED TO FISCAL 1996
    
 
     Net Sales.  Net sales were $158.7 million for fiscal 1997, an increase of
$17.8 million or 12.6% compared to $140.9 million for fiscal 1996. The increase
in net sales was attributed to a material increase in unit volume of material
handlers and a moderate increase in sales volume of excavators and service
parts. The introduction of the new excavator models XL 2200 and XL 2210 in 1997
assisted in the excavator unit increase. Price increases affecting all three
product lines had a modest favorable impact. Net sales of excavators were $57.4
million for fiscal 1997, an increase of $2.3 million or 4.1% compared to $55.1
million for fiscal 1996. Net sales of material handlers were $84.0 million for
fiscal 1997, an increase of $13.6 million or 19.3% compared to $70.4 million for
fiscal 1996. Net sales of service parts was $17.3 million for fiscal 1997, an
increase of $1.9 million or 12.3% compared to $15.4 million for fiscal 1996.
Although the Company expects net sales to increase in the future, it
 
                                       15
<PAGE>   17
 
anticipates that the rate of growth, especially with respect to sales of
material handlers, will not continue at the rate of growth experienced in 1997.
 
   
     Gross Profit.  Gross profit amounted to $38.0 million for fiscal 1997, an
increase of $5.2 million or 15.8% compared to $32.8 million for fiscal 1996.
Gross profit as a percentage of net sales increased to 24.0% for fiscal 1997
from 23.3% for fiscal 1996, primarily due to improved production efficiencies
and the economies of higher production volume.
    
 
     Research and Development and Product Engineering Costs.  Research and
development and product engineering cost was $3.6 million for fiscal 1997, an
increase of $0.6 million or 18.3% compared to $3.1 million for fiscal 1996. The
increase is due to the addition of engineering personnel to support new product
development.
 
   
     Selling, General and Administrative Expenses.  SG&A expense was $13.7
million for fiscal 1997, an increase of $1.9 million or 16.1% compared to $11.8
million for fiscal 1996. This increase is attributed to the addition of
marketing field sales and service representatives to improve service to the
distributor organization. In addition the higher unit volume of shipments in
fiscal 1997 increased the interest expense for dealer floor plan and retail
subsidy above the 1996 expense level.
    
 
     Interest Expense.  Interest expense was $0.7 million for fiscal 1997, a
decrease of $2.4 million or 77.6% compared to $3.1 million for fiscal 1996. This
reduction is the result of the application of the net proceeds of the Company's
initial public offering to reduce outstanding indebtedness on September 3, 1996.
 
     Other.  Other expense was $0.3 million for fiscal 1997, a decrease of $0.8
million or 74.8% compared to $1.0 million in fiscal 1996. In 1996 other expense
included a charge of $0.8 million for settlement of a distributor litigation.
 
   
     Income Tax Provision.  Income tax expense was $7.7 million for fiscal 1997,
an increase of $2.2 million or 39.9% compared to $5.5 million for fiscal 1996,
and representing an effective tax rate of 39.1% in 1997 and 40.0% in 1996.
    
 
     Extraordinary Item.  An extraordinary charge of $1.0 million, net of taxes,
related to early extinguishment of senior and subordinated debt was incurred in
September 1996 to write off unamortized deferred financing costs and the
discount on subordinated debt which was paid off with proceeds from the
Company's initial public offering on September 3, 1996.
 
     Net Income.  Net income was $12.0 million for fiscal 1997, an increase of
$4.7 million or 64.0% compared to $7.3 million for fiscal 1996. This increase
results from the higher level of sales in fiscal 1997 generating increased
operating margins and reduced debt from the 1996 initial public offering
lowering interest expense.
 
   
     Diluted Earnings Per Common Share After Extraordinary Item.  Earnings per
common share after extraordinary item were $1.33 for fiscal 1997, an increase of
$0.29 or 27.9% from $1.04 for fiscal year 1996, reflecting the $4.7 million
increase in net income described above.
    
 
FISCAL 1996 COMPARED TO FISCAL 1995
 
     Net Sales.  Net sales were $140.9 million for fiscal 1996, an increase of
$22.5 million or 19.0% compared to $118.4 million for fiscal 1995. The increase
in net sales was substantially attributable to a significant increase in unit
volume of material handlers and a moderate increase in unit volume of
excavators. Price increases affecting both product lines had a modest favorable
impact. Net sales of excavators were $55.1 million for fiscal 1996, an increase
of $5.9 million or 12.0% compared to $49.2 million for fiscal 1995. Net sales of
material handlers were $70.4 million for fiscal 1996, an increase of $16.8
million or 31.3% compared to $53.6 million for fiscal 1995. Net sales of service
parts were $15.4 million for fiscal 1996, a decrease of $0.2 million or 1.2%
compared to $15.6 million for fiscal 1995. In 1995 $0.6 million of the $15.6
million in service parts net sales was revenue associated with a one-time
military subcontract.
 
     Gross Profit.  Gross profit amounted to $32.8 million for fiscal 1996, an
increase of $7.0 million or 27.2% compared to $25.8 million for fiscal 1995.
Gross profit as a percentage of net sales increased to 23.3% for fiscal
 
                                       16
<PAGE>   18
 
1996 from 21.8% for fiscal 1995, primarily due to improved production
efficiencies and the economies of higher production volume.
 
     Research and Development and Product Engineering Costs.  Research and
development and product engineering cost was $3.1 million for fiscal 1996, an
increase of $0.6 million or 23.0% compared to $2.5 million for fiscal 1995. The
increase is due to the addition of engineering personnel to support new product
development.
 
   
     Selling, General and Administrative Expenses.  SG&A expense was $11.8
million for fiscal 1996, an increase of $1.3 million or 12.5% compared to $10.5
million for fiscal 1995. The increase is due to expenses related to the 1996 Con
Expo, a major trade show held every three years, increased dealer floor plan
interest and retail subsidy tied to the increased sales volume, and higher legal
expenses in connection with the settlement of litigation.
    
 
     Interest Expense.  Interest expense was $3.1 million for fiscal 1996, an
increase of $1.5 million or 89.3% compared to $1.6 million for fiscal 1995. This
increase in interest expense was due to increased borrowings in connection with
the recapitalization which occurred on October 13, 1995. Fourth quarter 1996
interest was reduced as a result of the application of the net proceeds of the
Company's initial public offering to reduce outstanding indebtedness.
 
   
     Income Tax Provision.  Income tax expense was $5.5 million for fiscal 1996,
an increase of $1.8 million or 49.5% compared to $3.7 million for fiscal 1995,
and represented an effective tax rate of 40.0% in 1996 and 35.8% in 1995.
    
 
     Extraordinary Item.  An extraordinary charge of $1.0 million, net of taxes,
related to early extinguishment of senior and subordinated debt was incurred in
September 1996 to write off unamortized deferred financing costs and the
discount on subordinated debt which was paid off with the proceeds from the
Company's initial public offering on September 3, 1996.
 
     Net Income.  Net income was $7.3 million for fiscal 1996, an increase of
$0.7 million or 10.7% compared to $6.6 million for fiscal 1995. The higher level
of sales in fiscal 1996 generated higher operating margins which were partially
offset by the additional interest cost related to the debt incurred with the
1995 Recapitalization and the extraordinary charge.
 
   
     Diluted Earnings Per Common Share After Extraordinary Item.  Earnings per
common share after extraordinary item were $1.04 for fiscal 1996, a decrease of
$0.13 or 11.1% from $1.17 for fiscal year 1995, principally as a result of the
extraordinary charge described above and a higher number of shares outstanding
after the initial public offering.
    
 
LIQUIDITY AND CAPITAL RESOURCES
 
   
     In September, 1996 Gradall completed the initial public offering of
2,950,000 newly issued shares of common stock at $10.00 per share. As part of
the offering, existing shareholders sold 1,075,000 shares of common stock
including the shares received upon exercise of all the warrants issued in
connection with the 1995 Recapitalization. The $26.9 million of net proceeds to
the Company were used to redeem $2.0 million in preferred stock, to repay in
full $10.0 million in subordinated debt and $9.6 million in senior term debt,
and to reduce the Company's revolving credit borrowings by $5.4 million. As a
result of the application of the proceeds from the initial public offering,
Gradall incurred an after tax extraordinary charge in the fourth quarter of 1996
of $1.6 million net of $0.6 million of income tax benefits, to write off
unamortized discount and deferred financing charges related to the warrants and
the repayment of indebtedness.
    
 
     The Company has funded its operations primarily with cash generated from
operations. The Company generated net cash from operating activities of $0.2
million during the first three months of 1998 compared to $0.8 million used
during the first three months of 1997. Net cash from operating activities
resulted from the sum of $3.1 million of net income, $0.6 million of
depreciation and amortization and $0.2 million from post retirement benefit, net
of deferred taxes, reduced by $3.6 million of net cash used by changes in
operating assets and liabilities, primarily a decrease in accounts payable.
 
                                       17
<PAGE>   19
 
     For the first three months of 1998 net borrowings under the Company's
revolving credit facility increased $1.3 million primarily as a result of the
reduction of accounts payable, increase in inventory and purchase of capital
equipment.
 
   
     Net cash used by investing activities, consisting of purchases of property
and equipment, was $5.3 million in 1997 and $2.3 million in 1996. These capital
expenditures were incurred primarily in connection with the Company's multi-year
program to increase production efficiencies, labor productivity and the output
of the Company's manufacturing facility through investments in new capital
equipment. The Company's capital investments in 1997 under this program totaled
$5.3 million which were funded by cash from operations and borrowings from
available credit facilities. Management expects to invest approximately $8.1
million of additional capital in 1998 for improvements under the multi-year
program. For the first three months of 1998, the Company expended $1.0 million
for new equipment and permanent tooling.
    
 
   
     As of March 31, 1998 the Company had borrowed $10.9 million under its $25
million bank revolving credit facility which is secured principally by the
Company's inventory and receivables. Interest is calculated, at the Company's
option, at LIBOR plus 1.0% and/or a commercial bank's base rate less 0.5% and
requires a commitment fee of 0.25% per annum on the unused portion of the
revolving credit commitment. At March 31, 1998, $14.1 million was available for
future borrowings under the revolver and the Company was in compliance with all
financial covenants. On March 31, 1998, the average annual interest rate under
the facility was 7.38%. The Company is not required to make any principal
repayments of the amount outstanding under the facility until August 31, 1999.
The facility requires the Company to maintain various financial ratios and
defined levels of tangible net worth and to restrict asset acquisitions and
dispositions, additional indebtedness and certain payments, including cash
dividends.
    
 
     A substantial amount of the Company's working capital is invested in
accounts receivable and inventories. The Company periodically reviews accounts
receivable for noncollectibility and inventories for obsolescence and
establishes allowances that it believes are appropriate. In addition, the
Company continuously monitors the level of its purchase orders for raw materials
and correlates these orders, and its inventory balances of various raw
materials, to its current production schedule. To avoid shortages of raw
materials during periods of increased demand, the Company may from time to time
increase its level of purchases to meet its anticipated future level of
production.
 
   
     The Board of Directors has approved in principle the Capacity Expansion
Program which is intended to raise capacity in excess of 50% over the next three
to five years. The Capacity Expansion Program will require a $30 to $50 million
investment over this time frame. The Company has entered into no commitments
with respect to the Capacity Expansion Program and may alter or revise the
Capacity Expansion Program based upon changes in market demand and/or economic
conditions. The Company believes that cash flow from operations together with
funds available under its revolving credit facility will be adequate to fund its
working capital and capital expenditure requirements for the foreseeable future.
    
 
   
     As part of an ongoing Internal Revenue Service ("IRS") examination, the
Company was recently notified of certain potential adjustments with respect to
prior years. The potential adjustments relate to the valuation of inventory and
the calculation of the Company's gain upon the distribution to shareholders of
shares in certain subsidiaries in connection with the 1995 Recapitalization of
the Company. The examination is ongoing and the IRS may raise additional issues.
At present, the IRS has not asserted any tax deficiency against the Company. The
Company plans to defend these issues vigorously.
    
 
IMPACT OF THE "YEAR 2000 ISSUE"
 
     The "Year 2000 Issue" is the result of computer systems that were
programmed in prior years using a two-digit representation for the year.
Consequently, in the year 2000, date-sensitive computer programs may interpret
the date "00" as 1900 rather than 2000. The Company's operating units have
completed an initial assessment of the systems affected by the Year 2000 Issue,
and are formulating action plans to correct or replace these programs by a
target date of September 30, 1999.
 
                                       18
<PAGE>   20
 
   
     The Company will be required to modify or replace several internally
developed software packages along with purchased software packages used
internally. The Company will use internal resources to modify programs, and will
upgrade where necessary. Estimates of the total remaining cost of the year 2000
project have been finalized and are not expected to have a material adverse
effect on future operating results or cash flows.
    
 
INFLATION
 
     The overall impact of the low rate of inflation in recent years has had no
significant impact on the Company.
 
ACCOUNTING PRONOUNCEMENTS
 
   
     In March 1995, The Financial Accounting Standard Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 121, "Accounting for
the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed
Of," for the year ended December 31, 1996. The adoption of SFAS No. 121 had no
impact on the Company's consolidated financial position, results of operations,
or cash flows.
    
 
     In October 1995, the FASB issued SFAS No. 123, "Accounting for Stock Based
Compensation," effective for transactions entered into in fiscal years that
begin after December 15, 1995. The Company adopted this standard's disclosure
only provisions for the year ended December 31, 1996. The adoption of this
standard had no impact on the Company's consolidated financial position, results
of operation, or cash flows.
 
     In March 1997, the FASB issued SFAS No. 128, "Earnings Per Share,"
effective for the periods ending after December 15, 1997. The Company adopted
SFAS No. 128, "Earnings Per Share" in the fourth quarter of 1997. The impact of
implementing SFAS No. 128 is discussed in Note 14 to the Consolidated Financial
Statements.
 
     In March 1997, the FASB also issued SFAS No. 129, "Disclosure of
Information about Capital Structure," effective for fiscal years ending after
December 15, 1997. The adoption of this standard had no impact on the Company's
consolidated financial position, results of operation, or cash flows.
 
     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," and SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information," both effective for fiscal years beginning after December
15, 1997. The adoption of this standard had no impact on the Company's
consolidated financial position, results of operation, or cash flows.
 
     In February 1998, the FASB issued SFAS No. 132, "Employers' Disclosures
About Pensions and other Postretirement Benefits," which is effective for
financial years beginning after December 31, 1997. The Company will adopt the
provisions of SFAS for its fiscal year ending December 31, 1998, but does not
expect such adoption to have material impact on the financial statements of the
Company.

                                    BUSINESS
 
OVERVIEW
 
     Gradall is a leading manufacturer of telescopic hydraulic excavators and
rough-terrain variable reach material handlers as well as related service parts.
The Company's products are marketed under the widely respected Gradall tradename
and are distinguished by their telescopic boom technology, versatility,
productivity and reliability. Gradall's telescopic booms, which are manufactured
from high-strength specialty steel, are unique both in their shape and
engineering design, which provide added strength with minimal weight, and, in
the case of excavators, in their ability to rotate a full 360 degrees. Gradall
products serve niche markets within the construction equipment industry and
typically command premium prices. In 1997, total sales were $158.7 million,
comprised of $57.4 million in sales of excavators, $84.0 million in sales of
material handlers and $17.3 million in sales of service parts. Since January
1993, the Company has introduced 14 new products which accounted for in excess
of 60% of Gradall's net sales in 1997.
 
     Gradall excavators are typically used by general contractors and government
agencies for ditching, sloping, finished grading, general maintenance and
infrastructure projects. The Company's excavators are sold through approximately
48 independent distributors at approximately 152 locations throughout North
America. The introduction and ongoing development of the Company's XL Series
excavators featuring the unique Gradall rotating, telescopic booms with
high-pressure hydraulics have allowed the Company to continue to dominate its
traditional niche market of wheeled, telescopic boom excavators and to
strengthen its competitive position in the larger market of conventional crawler
excavators, a market historically dominated by knuckle-boom technology.
 
     Gradall rough-terrain variable reach material handlers are typically used
by residential, non-residential and institutional building contractors for
lifting, transporting and placing a wide variety of materials at their point of
use or storage. The Company's material handlers are sold through approximately
44 independent distributors at approximately 127 locations throughout North
America. In addition, Gradall material handlers are available at national rental
companies at over 250 locations. The Company continues to introduce new material
handlers with Gradall's unique 90 degrees rear-pivot steering, hydrostatic drive
and low profile design which provide an exceptional combination of
maneuverability, versatility and stability.
 
   
     Gradall's strategy is to design and produce high quality hydraulic
excavators and material handlers for niche markets while simultaneously reducing
manufacturing costs and increasing production efficiencies. Gradall's ability to
design and customize each of its product lines to fit the specifications of its
customers augments the uniqueness of the Company's products. In 1995, the
Company commenced a multi-year program designed to expand plant capacity and
reduce production costs by improving labor efficiency, equipment, productivity
and quality. The Company invested $4.2 million in 1995, $2.3 million in 1996 and
$5.3 million in 1997 for capital improvements pursuant to this program. During
1998, the Company plans to invest approximately $8.1 million for additional
capital improvements under this program. Management believes that these
strategies have enabled the Company to increase substantially its profitability
in recent years. In addition, the Board of Directors has approved in principle
the Capacity Expansion Program which is intended to raise capacity in excess of
50% over the next three to five years. The Capacity Expansion Program will
require a $30 to $50 million investment over this time frame. The Company has
entered into no commitments with respect to the Capacity Expansion Program and
may alter or revise the Capacity Expansion Program based upon changes in market
demand and/or economic conditions. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
    
 
THE INDUSTRY
 
     Gradall competes principally in the construction equipment industry. In
1997, the Company estimates that total construction equipment spending exceeded
$47 billion. In 1997, the value of new construction put in place was over $609
billion. The construction equipment industry is highly competitive and global in
scope. The U.S. construction equipment industry consists of about 700
manufacturers. The demand for construction equipment is largely driven by
general economic conditions.
 
                                       20
<PAGE>   22
 
     Since the beginning of 1993, the construction equipment industry has grown
due to improved general economic conditions, increased public funding for
infrastructure projects and increased demand for rental equipment. The U.S.
Department of Commerce has estimated that more than half of the country's major
highways and one-third of the bridges are in need of some repair. Gradall
management believes that the need for such repairs will continue to benefit the
demand for the Company's products to the extent that funding for such repairs is
available. In addition, construction machinery rentals have increased due to the
need for specific, high-cost equipment for short durations, distributors'
ability to convert rentals into subsequent sales and the lack of an investment
tax credit for purchasers. In particular, the market for material handlers,
which typically are rented by distributors or other rental companies before
being sold in the retail market, has notably increased over the past several
years consistent with the trend towards rental of construction equipment.
Another important element of the current demand for construction machinery is
the replacement of older machines with new and more versatile ones. The Company
believes that the present popularity of machines with multiple functions, faster
work cycles, ease of transport and special attachments, such as Gradall
products, will continue in the future.
 
     Excavators.  The total market for hydraulic excavators in the U.S. grew
from approximately 11,000 units in 1993 to over 19,000 units in 1997. The growth
in the market is due to improved general economic conditions and expanding
applications of hydraulic excavators. Excavators were traditionally used for
earth moving and below-ground applications such as trenching, road construction,
site development, mining and irrigation. The use of excavators has expanded to
include many above-ground applications such as demolition, bridge work,
hazardous waste clean-up, scrap handling and forestry work as well as
applications at industrial sites such as mines and steel mills.
 
     The excavator market may be divided into two product categories consisting
of track-mounted "crawler" excavators (which is further divided into several
size classes) and wheel-mounted "wheeled" excavators, which in recent years have
constituted approximately 97% and 3% of the total market for excavators,
respectively. The conventional crawler excavator market has been traditionally
dominated by knuckle-boom technology. The Company manufactures telescopic boom
crawler excavators in three size classes -- 12-14 tons, 19-21 tons and 24-28
tons -- which size classes in 1997 accounted for approximately 9%, 21% and 9% of
the total excavator market, respectively, for a total of approximately 40%. The
remainder of the crawler excavator market is represented by size classes which
are smaller or larger than the sizes currently manufactured by the Company.
Based on industry data, the Company estimates that its market share of the
crawler excavator market in which it competes is approximately 1%; however, its
unit sales of crawler excavators have increased at a compounded annual growth
rate of 38% over the past three years.
 
     Gradall is a leading manufacturer of wheeled telescopic boom excavators.
Based on industry data, the company estimates that its market share of wheeled
excavators exceeded 45% and that its market share of highway speed, telescopic
boom excavators is 85-90%.
 
     Material handlers.  The market for rough-terrain variable reach material
handlers has experienced dynamic growth in recent years due to new applications,
increased rental demand and displacement of straight-mast forklifts and small
rough-terrain cranes. The retail market for material handlers has grown from
approximately 1,900 units in 1993 to more than 8,500 units in 1997. Material
handlers are typically used for lifting, transporting and placing a wide variety
of materials such as bricks, blocks, lumber, drywall, structural steel and
roofing materials at their point of use or storage. The increased use of new
attachments such as buckets, augers, winches, truss booms, side shifting/fork
positioning carriages and swing carriages has contributed to the development of
new applications of material handlers.
 
     The rough-terrain variable reach material handler market is divided into
several size classes. The Company manufactures and markets material handlers in
three size classes -- 6-7,000 lbs., 8-9,000 lbs. and 10,000 lbs. and over, which
size classes in the aggregate represent over 94% of the total market for
material handlers. Based on industry data, the Company estimates that its market
share of rough-terrain variable reach material handlers is approximately 16%.

GROWTH STRATEGY
 
     The Company's growth strategy is to design and produce high quality
hydraulic excavators and material handlers for niche markets while
simultaneously reducing manufacturing costs and increasing production capacity.
Since 1993, the Company introduced 14 new products, its sales increased from
$72.2 million in 1993 to $158.7 million in 1997 and operating income increased
from $1.8 million in 1993 to $20.6 million in 1997. The key components of the
Company's strategy are:
 
     Develop unique products.  The Company remains committed to devoting
significant resources toward engineering and producing unique excavators and
material handlers. With the development of its XL Series excavators, the Company
introduced new products to the conventional crawler excavator market. The XL
Series excavators are exceptional because they combine the versatility of the
Gradall rotating, telescopic boom with the productivity of high-pressure
hydraulics. Shipments of the XL 2200, the latest XL Series model, which competes
in the 12-14 ton size class, commenced in May 1997, and this model has been well
received by distributors and customers. In mid-1997 the Company introduced the
newest XL model, XL2210, which is operated with a remote control device, making
it popular for steel and aluminum metal mill maintenance work as well as
hazardous waste cleanup and other potentially dangerous jobs. In July 1997,
Gradall introduced a new D Series material handler in the 10,000 lbs. and over
size class which is one of the largest material handlers in the industry. In
January 1998, the Company introduced seven new D Series models, completing the D
Series family. The eight new D Series models provide state of the industry
operator protection, new instrumentation, wider seating and excellent visibility
in all directions. The machines are designed for easy operation, shortening the
operator training process and encouraging faster, more efficient work with
advantages like no-shift transmissions. The Company's product development
engineers are currently designing additional new excavators and material
handlers which Gradall plans to market in the near future.
 
     Target niche markets.  The Company is working to continue its leading
position in its traditional niche market of highway speed, telescopic boom
excavators and to gain a leading position in several niche markets in the
conventional crawler market. Prior to 1993, the Company focused on the wheeled
excavator market which represents approximately 3% of the total excavator
market. Although this niche market accounts for a small portion of the overall
excavator market, it is an increasing market that generates consistent profit
margins. With the introduction of the XL Series excavators in 1993, the Company
significantly strengthened its competitive position in several size classes of
the conventional crawler excavator market which in the aggregate currently
represent approximately 40% of that market. Gradall believes that it is
well-positioned to take advantage of the niches in the crawler excavator market
which demand premium full-featured products. In the material handler market, the
Company focuses on the segment which demands a reliable premium product that
offers a high level of versatility and maneuverability. The Company believes it
is well-positioned to compete in this dynamically growing market.
 
   
     Improve manufacturing processes.  An important element of Gradall's growth
strategy is to expand profit margins through improved manufacturing processes.
In 1995, the Company commenced a multi-year program designed to expand plant
capacity and reduce production costs by increasing labor efficiency and
equipment productivity and improving quality. The Company invested $4.2 million
in 1995, $2.3 million in 1996 and $5.3 million in 1997 for capital improvements
pursuant to this program. During 1998, the Company plans to invest approximately
$8.1 million for additional capital improvements under this program. The recent
capital improvements have included robotic welding systems, fabrication
equipment and direct computer-controlled equipment for cellular production. In
addition, the Board of Directors has approved in principle the Capacity
Expansion Program which is intended to raise capacity in excess of 50% over the
next three to five years. The Capacity Expansion Program will require a $30 to
$50 million investment over this time frame. The Company has entered into no
commitments with respect to the Capacity Expansion Program and may alter or
revise the Capacity Expansion Program based upon changes in market demand and/or
economic conditions. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity And Capital Resources." Gradall
has also adopted programs designed to reward its employees for improvements in
overall productivity and profitability. In addition, the Company has implemented
aggressive quality programs in the areas of statistical process control,
warranty reduction and quality assurance. Gradall believes its recent and
planned
    
 
                                       22
<PAGE>   24
 
investments in automation and technology, material control, productivity
incentives and quality programs should improve its manufacturing processes and
benefit profit margins in the future.
 
     Emphasize quality.  Gradall has adopted a "continuous improvement" strategy
for every facet of its operation. The Company has carried the continuous
improvement concept beyond the scope of the traditional quality definition to
include product development and employee training and development. This strategy
has led to significant reductions in the Company's total cost of quality
(defined as warranty, rework and scrap expenses), which declined from 2.6% of
sales in 1993 to 1.5% in 1997. The Company has implemented statistical process
controls, a monitored product quality review program and a formal supplier
quality assurance program.
 
     Increase distributor support.  The Company believes that its distribution
network is among the strongest in the industry and a core strength for its
future growth. The Company plans to further enhance its distribution network by
continuing to produce unique new products, provide marketing and sales support
through its regional sales managers, and provide technical and service support
through its district service managers.
 
     Expand service parts business.  Management has focused on expanding the
Company's service parts business to increase revenues and profits by taking
advantage of the growth in the working population of Gradall excavators and
material handlers. As a part of this focus, the Company has implemented the
Gradall On Line Distributor ("GOLD") computer system which links the Company and
its distributors to facilitate communications regarding orders, availability and
other information involving Gradall service parts. In 1997, the Company invested
significant resources toward the development of CD ROM operators, service and
parts manuals which will be available to all dealers in 1998. Service parts
sales and marketing activities are supported by three regional parts managers
who are dispersed geographically throughout the U.S.
 
     Pursue joint ventures, international business opportunities and strategic
acquisitions.  Although substantially all of the Company's business has been
focused in North America, the Company believes its increased product development
efforts should enable the Company to take advantage of international
opportunities, including infrastructure development in emerging markets in the
former Soviet Union and Asia. The Company currently has a joint venture to
manufacture and market material handlers in Eastern Europe and is exploring
other international opportunities. In addition, the Company has embarked on a
program to obtain its ISO 9001 registration in order to assist the international
marketing of its products. The audit for this registration is scheduled for the
fourth quarter 1998. The Company believes there is opportunity to grow through
acquisitions, by participating in the current trend of consolidation in the
construction equipment industry.
 
PRODUCTS AND MARKETS
 
     The Company engineers, manufactures and markets premium hydraulic
excavators and material handlers which incorporate Gradall's unique design
features. In addition, the Company manufactures and markets service parts for
its excavators and material handlers. Since January 1993, the Company has
introduced 14 new products which accounted for in excess of 60% of total sales
in 1997.

                                   EXCAVATORS
 
     All Gradall excavators are distinguished by their rotating telescopic boom
technology, versatility, productivity and reliability. Gradall excavators are
typically used for ditching, sloping, finished grading and general maintenance
which often require precise boom and bucket movements which conventional
knuckle-boom excavators cannot provide. Gradall excavators are also used at
various construction sites with restricted overhead clearance areas or other
operating requirements where it would be difficult for conventional knuckle-boom
excavators to operate. Gradall's highway speed excavators are particularly
useful to customers who require their equipment to be at multiple locations
within short periods of time. Gradall excavators compete in the wheeled
excavator category and three size classes in the crawler excavator category.
 
     A brief description of Gradall excavator models is as follows:
 
     G3WD Series E.  This model is a single-engine highway speed excavator
purchased primarily by state and local government agencies. The mobility and
versatility of this product are its primary market strengths since it enables
the user to do the work of three machines -- an excavator, grader and wheeled
loader. The Company's ability to customize this product to meet the
specifications required by government agency bid contracts gives it a particular
competitive advantage.
 
     XL Series.  The Company formally introduced the XL Series in March 1993 to
enhance its competitive position in the larger market segment of conventional
crawler excavators. The XL Crawler Series products compete in the 12-14 ton,
19-21 ton and 24-28 ton size classes which size classes in the aggregate
constitute approximately 40% of the entire excavator market. The XL Series
products combine the versatility of the Gradall telescopic boom technology with
the performance of high-pressure hydraulics. The XL Series products have more
than twice the productivity and efficiency of the Gradall models they replaced.
 
     XL2000 Series.  Shipments of the new crawler model XL2200 commenced in May
1997, and it competes in the 12-14 ton class which size class represents
approximately 9% of the total excavator market. This model is designed to meet
the needs of residential and general contractors. In August 1997, the Company
commenced shipments of a remote controlled crawler model XL2210, which is a
special industrial version for use in mines and steel mills. During 1998, the
Company plans to introduce a non-highway speed wheeled version of the XL2000
series.
 
   
     XL4000 Series.  This model competes in the 19-21 ton class which size class
represents approximately 21% of the total excavator market. The XL4000 Series is
available in both wheeled and crawler versions. This model is widely used by
municipalities and general contractors.
    
 
     XL5000 Series.  This model competes in the 24-28 ton class traditionally
dominated by conventional crawler knuckle-boom excavators. This size class
accounts for approximately 9% of the total excavator market. The XL5000 Series
is the largest high-pressure hydraulic excavator manufactured by the Company and
is available in both wheeled and crawler versions. It is well-accepted among
infrastructure and highway contractors.
 
     In addition to the above-mentioned models which are primarily used in
construction applications, the Company offers excavators in both wheeled and
crawler versions which are used in industrial applications such as mines and
steel mills, respectively. Certain specialized Gradall crawler models are the
accepted standard in the steel industry for cleaning furnaces and ladles and for
other steel mill applications. Gradall excavators have also been specially
designed for mine scaling applications at limestone and salt mines.
 
     The primary features of Gradall excavators are:
 
     Telescopic boom.  The rotating, telescopic boom is well-known for its
versatility and strength. The unique design is excellent for production work
such as trenching and earth moving as well as precision work including finished
grading and clean-up.
 
     Wheeled carriers.  The Company's highway speed, wheeled carriers are
designed and manufactured by Gradall to meet the needs for a reliable and
durable carrier. They are offered in two, four or six-wheel drive
configurations.
 
                                       24
<PAGE>   26
 
     Remote control, single cab operation.  All Gradall highway speed wheeled
excavators are designed with two cabs -- one for the operation of the carrier
and the other for the operation of the excavator. They are engineered so that
one operator can control the carrier by remote control from the excavator cab.
This allows for greater versatility and adds significantly to the productivity
of the machine.
 
     Crawler undercarriages.  Gradall crawler undercarriages are specifically
designed and manufactured by the Company to provide the speed and stability
requirements of XL Series excavators.
 
     Options/attachments.  In addition to a variety of standard features,
Gradall also offers specialized options as requested by customers including air
conditioning, work lights, vandal covers and special auxiliary hydraulics. In
1996, Gradall introduced the "telestick" boom attachment which extends the reach
of the XL4000 and XL5000 Series excavators approximately 50% to 45'5" and 50'9",
respectively.
 
                               MATERIAL HANDLERS
 
   
     All Gradall material handlers are renowned for their maneuverability,
versatility and dependability. Gradall material handlers are typically used for
lifting, transporting and placing a variety of materials such as bricks, blocks,
lumber, drywall, structural steel and roofing materials at their point of use or
storage. The Company manufactures five basic models of material handlers in
three size classes.
    
 
     A brief description of Gradall material handler models is as follows:
 
     522/524D.  The 522/524D was introduced in January 1998 and competes in the
6-7,000 lbs. class which size class represents approximately 49% of the total
material handler market. It is available in both two-section and three-section
booms which provide a maximum lift height of 24" and 32', respectively. This
model is very cost efficient and is ideally suited for less demanding
applications.
 
     534D-6.  The 534D-6 was introduced in January 1998 and is the most popular
Gradall material handler. It also competes in the 6-7,000 lbs. class and has a
maximum lift height of 36'. This model is very well-accepted among mason and
roofing contractors.
 
     534D-9.  The 534D-9 was introduced in January 1998 and competes in the
8-9,000 lbs. class which size class represents approximately 35% of the market
and has a maximum lift height of 40'. This model has a strong appeal to framing
contractors.
 
   
     534D-10.  The 534D-10 was introduced in January 1998 and competes in the
10,000 lbs. and over class which size class represents approximately 10% of the
market. It has a maximum lift height of 40' and is ideally suited for operations
requiring heavy lifting. This model has stabilizers as standard equipment to
increase its overall capacity at full reach.
    
 
     544D.  The 544D was introduced in July 1997 and also competes in the 10,000
lbs. and over class. It is one of the industry's largest material handlers and
has a maximum lift height of 55'. This model permits working on buildings as
high as six stories and also includes stabilizers as standard equipment.
 
     The primary features of Gradall material handlers are:
 
     90 degree rear-pivot steering.  This is the key feature of a Gradall
material handler which provides excellent maneuverability by allowing the
machines to turn within a tight radius. The design keeps the forks and the load
inside the turning radius while providing the ability to maneuver the vehicle in
tight areas.
 
     Strong and versatile boom.  Gradall material handlers feature one of the
industry's strongest booms. The Gradall boom is capable of handling a variety of
attachments which leads to a high degree of versatility. In addition, Gradall
has a proprietary design to facilitate switching the attachments called
QuickSwitch.
 
     Low profile.  A significant advantage of the Gradall material handler is
its low overall height. The vehicle can move under doorways as low as eight feet
while maintaining excellent ground clearance.
 
     Hydrostatic drive.  Hydrostatic drive provides the benefits of easier,
no-shift operations, inching capability, quick accelerations and a smooth, even
ride.
 
                                       25
<PAGE>   27
 
     Stability.  Gradall material handlers operate with the industry's longest
wheelbase and shortest overall length which increase their capacity and
stability. Their engine is mid-mounted within the frame providing uniform weight
distribution and improved visibility.
 
                                 SERVICE PARTS
 
     In addition to engineering, manufacturing and marketing hydraulic
excavators and material handlers, the Company produces and sells related service
parts. This is an important source of revenue and profitability for the Company.
Since the Company's products are kept operational for years with parts and
service support, each Gradall product that enters the market provides the
Company with a potential long-term revenue source. Sales of service parts
typically generate high gross margins and historically have been less sensitive
to industry cycles.
 
     In order to increase sales of service parts in the face of growing
competition, the Company focuses on parts availability, marketing and sales
activities. As a part of this focus, the Company has implemented the Gradall On
Line Distributor ("GOLD") computer system which links the Company and its
distributors to facilitate communications regarding orders, availability and
other information involving Gradall service parts. The Company emphasizes the
importance of stocking and marketing service parts and has developed a delivery
system to provide quick shipment of emergency and unit down parts. The Company
provides same day shipment on unit down orders and promotes distributor
incentives for stock orders. In 1997, the Company invested significant resources
to the development of CD ROM operators, service and parts manuals which will be
available to all dealers in 1998.
 
SPECIALIZED MACHINES
 
     Gradall has the ability to modify its products to suit the specific needs
of its customers. This ability to produce specialized machines is a part of
Gradall's overall strategy to serve specialty, higher margin markets within the
construction equipment industry. Over 30% of all Gradall excavators are modified
from standard models, and approximately 10% of all Gradall material handlers are
customized with add-on and/or special attachments. Gradall is able to design and
produce specialized machines while meeting the delivery schedule of its
customers. Some of the specialized machines developed by the Company are now
being marketed as standard models; for example, special excavators created for
mine scaling, steel mills and other special industrial applications have become
Gradall standard models.
 
MARKETING & DISTRIBUTION
 
     The Company primarily markets and distributes its products through a
network of independent distributors and rental companies who, in turn, sell or
rent the products to end-users. The Company also sells directly through its own
marketing staff to certain major accounts as well as to customers located
outside the United States.
 
     The Company has agreements with its distributors under which the
distributors purchase products from the Company at agreed upon prices for resale
within the distributor's territory. Although the Company's distributors are not
required to purchase any minimum number of products, they are required to
maintain agreed-upon inventory levels. Either party may terminate the
distributor agreement upon the occurrence of certain events, including
bankruptcy or breach, or in the event either party is dissatisfied with the
other party's performance, upon thirty days notice after a sixty day dispute
resolution procedure. In addition to the Company's products, distributors
typically sell construction equipment manufactured by third parties, including
competitors of the Company.
 
     Gradall excavators are primarily used by general contractors and government
agencies. Gradall material handlers are customarily used by residential,
non-residential and institutional building contractors. Since these are distinct
user bases, the Company markets excavators and material handlers and their
related service parts through two separate distribution networks. The Company's
excavator distribution network is comprised of approximately 48 independent
distributors at approximately 152 locations in North America. The Company's
material handler distribution network is composed of approximately 44
independent distributors at approximately 127 locations. In
 
                                       26

addition, Gradall material handlers are available at national rental companies
at over 250 locations. No single distributor or rental company accounted for
more than 10% of the Company's sales in 1997.
 
     The Company believes that its ongoing distributor support and training
programs help enhance the competitiveness and increase the strength of its
distribution network. The Company supports the sales, service and rental
activities of its distributors with product advertising, sales literature,
product training and major trade show participation. The independent
distribution network is serviced by the Company's five regional sales managers
for excavators and six regional sales managers for material handlers. Each
regional sales manager is also responsible for developing new distributors
within his region.
 
     The Company provides its distributors with product financing through
agreements with third party financing companies. Such financings include a
Wholesale Floor Plan for distributors and a Retail Finance Plan for end-users,
each with reduced interest rates subsidized by the Company, and a Rental Plan
for distributors.
 
     The Company supports the servicing of its products through a field service
organization consisting of four district service managers located throughout the
United States. The district service managers provide service training and
technical support to the distributors, and act as a liaison among customers,
distributors and the Company on service related matters. The district service
managers are also involved in service parts marketing, sales call support and
product demonstrations. In addition, the Company has three service
representatives at its principal offices who are responsible for fulfilling the
Company's commitment to product reliability.
 
MANUFACTURING
 
     The Company fabricates, welds, machines and assembles the chassis,
telescopic booms, attachments and many component parts for its excavators and
material handlers. The goals of the Company's manufacturing operation are
quality, efficiency, productivity, cost control and on-time delivery. The
Company strives to develop its manufacturing capacity, productivity and quality
through automation and technology, material control, productivity incentives for
employees and quality programs.
 
   
     Automation and technology.  In 1995, the Company commenced a multi-year
program designed to expand plant capacity and reduce production costs by
improving labor efficiency, equipment productivity and quality. The Company
invested $4.2 million in 1995, $2.3 million in 1996 and $5.3 million in 1997 for
capital improvements pursuant to this program. Thus far, capital improvements
have included robotic welding systems, laser cutting machines, oxygen assist
plasma cutting machines and direct computer-controlled equipment designed for
cellular production. Planned expenditures will include additional robotic
welding systems, laser cutting machines, oxygen assist plasma cutting machines
and a large computerized boring machine. In addition, the Board of Directors has
approved in principle the Capacity Expansion Program which is intended to raise
capacity in excess of 50% over the next three to five years. The Capacity
Expansion Program will require a $30 to $50 million investment over this time
frame. The Company has entered into no commitments with respect to the Capacity
Expansion Program and may alter or revise the Capacity Expansion Program based
upon changes in market demand and/or economic conditions. Gradall believes that
the recently completed capital improvements, which have reduced production
costs, expanded plant capacity and improved quality, and planned capital
improvements, should benefit profit margins and increase unit output capacity in
the future.
    
 
     Material control.  The Company has instituted and continues to institute
material control improvements. These improvements include the introduction of
just-in-time inventory management, the relocation of certain inventory to the
shop floor to support cell manufacturing, the implementation of set-up reduction
programs and the reduction and control of obsolete and surplus inventory.
 
     Productivity incentives.  The Company operates a productivity sharing plan
for its unionized, hourly employees called "Gainsharing." Gainsharing is a group
incentive program that is calculated from a company-wide measure of
productivity. The productivity of the plant is measured against a base period.
Each employee receives a Gainshare bonus based upon the percentage increase in
productivity. The Company has an active labor management cooperative committee
which is supported by employee positive action teams. These teams implement
changes in the manufacturing processes which improve quality and productivity
which in turn support the Gainsharing program.
 
                                       27
<PAGE>   29
 
     Quality programs.  The Company has implemented comprehensive quality
programs, including the following:
 
     Statistical process control.  The Company maintains control charts in
machining, welding and assembly as well as a pre-shipment quality audit program
on finished machines. The Company plans to continue expanding the use of
statistical process control charts.
 
     Quality feedback/warranty reduction.  Gradall reviews critical quality
issues on an ongoing basis and initiates corrective actions. A computerized
warranty system captures early warning reports from field service managers as
well as details of warranty claims which provide additional input to the quality
feedback program.
 
     Supplier quality assurance.  The Company monitors supplier quality through
a computer system which records and tracks reports on defective material
allowing the Company to execute corrective action measures.
 
     Gradall's commitment to automation and technology, material control,
productivity incentives for employees and quality programs have improved the
capacity, productivity and quality of the Company's manufacturing operations.
From 1993 to 1997, the Company increased its unit production by 169.1% with only
a 33.5% increase in its workforce. The Company's total cost of quality (defined
as warranty, rework and scrap expenses) declined from 2.6% of sales in 1993 to
1.5% of sales in 1997.
 
ENGINEERING AND DESIGN
 
     Gradall believes that its engineering and design capabilities are among the
Company's major strengths. The engineering and design functions are closely
integrated with the Company's manufacturing and marketing activities. This
allows the Company to integrate new production technology with specific needs of
customers, resulting in expanded market opportunities and increased
profitability for the Company. In 1997, over 30% of Gradall's excavators were
modified from standard models to meet end-users' specific requirements.
 
     The Company's manufacturing engineers are involved in both product design
and implementation of capital improvements in order to maximize manufacturing
processes and efficiencies. In addition, the implementation of "concurrent
engineering," in which personnel from engineering, manufacturing, materials
procurement and marketing are simultaneously engaged in new product development
programs, has led to faster new product development time, reduced costs and
improved quality.
 
     Gradall has made significant investments in its engineering systems, which
currently include a computer-aided design (CAD) system with finite element
analysis (FEA) and three-dimensional solids design capabilities. These systems
have greatly expanded Gradall's design capabilities and has significantly
reduced the time required for engineering and design functions.
 
     Since 1993, the Company's engineering department personnel has increased by
approximately 80% in order to accelerate new product development.
 
COMPETITION
 
     The markets in which the Company operates are highly competitive. The
Company faces competition in each of its product lines from a number of
different manufacturers, some of which have greater financial and other
resources than the Company. The principal competitive factors affecting the
markets for the Company's products include performance, functionality, price,
brand recognition, customer service and support, and product availability.
 
     The excavator market may be divided into two product categories of
track-mounted "crawler" excavators (which is further divided into several size
classes) and wheel-mounted "wheeled" excavators. In recent years, crawler
excavators have constituted approximately 97% of the total market for excavators
and wheeled excavators have accounted for 3%. The conventional crawler excavator
market has been traditionally dominated by knuckle-boom technology. The leading
producers of conventional crawler excavators are Caterpillar Inc., Deere & Co.,
Hitachi Corporation and Komatsu, Ltd. The Company manufactures telescopic boom
crawler excavators in three size classes -- 12-14 tons, 19-21 tons and 24-28
tons -- which size classes in 1997 accounted for approximately 9%, 21% and 9% of
the total excavator market, respectively, for a total of approximately 40% of
the total market.
                                       28
<PAGE>   30
 
Gradall's XL Series excavators are designed to appeal to niche markets in these
size classes which require the versatility of the Gradall telescopic boom
technology with the performance of high-pressure hydraulics. The remainder of
the crawler excavator market is represented by size classes which are smaller or
larger than the sizes currently manufactured by the Company. Based on industry
data, the Company estimates that its market share of the crawler excavator
market in which it competes is approximately 1%; however, its unit sales of
crawler excavators have increased at a compounded annual growth rate of 38% over
the past three years.
 
     Gradall is a leading manufacturer of wheeled telescopic boom excavators.
Based on industry data, the Company estimates that its market share of all
wheeled excavators exceeds 45% and that its market share of highway speed,
telescopic boom excavators is 85-90%. The Company has only one competitor in the
highway speed, telescopic boom excavator market.
 
     The rough-terrain variable reach material handler market is divided into
several size classes. The Company manufactures and markets material handlers in
three size classes -- 6-7,000 lbs., 8-9,000 lbs. and 10,000 lbs. and over, which
in the aggregate represent over 94% of the total market for material handlers.
Based on industry data, the Company estimates that its market share of all
material handlers is approximately 16%. Other than Gradall, the principal
producers of variable reach material handlers are Caterpillar, Inc., Gehl, JCB
International Co., Ltd., and Omniquip International.
 
EMPLOYEES
 
   
     As of March 31, 1998, Gradall employed 695 people -- 461 hourly and 234
salaried. The Company's hourly employees are represented by the IAM and are
currently working under a three-year contract which will expire on April 16,
2000. The Company's current contract with the IAM was approved after a
three-week work stoppage which occurred in March 1997 when the union failed to
ratify a proposed new three-year contract. During the work stoppage the Company
was able to continue production and shipment, although at a reduced level. There
can be no assurance that the Company will be able to negotiate satisfactory
contracts with the union in the future or that the Company's union employees
will not participate in any work stoppage which could have a material adverse
effect on the operations of the Company.

                          DESCRIPTION OF CAPITAL STOCK
 
   
     Upon completion of the Offering, the authorized capital stock of the
Company will consist of 18,000,000 shares of Common Stock, par value $.001 per
share and 2,000,000 shares of Serial Preferred Stock, par value $.001 per share,
of which 9,445,734 shares of Common Stock will be issued and outstanding
(assuming the Underwriters' over-allotment option is not exercised) and no
shares of Serial Preferred Stock will be issued and outstanding. As of June 1,
1998, 518,786 shares of Common Stock were reserved for issuance pursuant to
outstanding options. The following description is a summary of the capital stock
and of the preferred stock purchase rights of the Company and is subject to and
qualified in its entirety by reference to the provisions of the Amended and
Restated Certificate of Incorporation, the Amended and Restated Bylaws of the
Company and the Rights Agreement dated as of May 29, 1998 between the Company
and ChaseMellon Shareholder Services, L.L.C., as Rights Agent, copies of which
are included as exhibits to the Registration Statement of which this Prospectus
is a part.
    
 
COMMON STOCK
 
     The issued and outstanding shares of Common Stock are, and the shares being
offered by the Company will be, when issued, fully paid and nonassessable. Each
outstanding share of Common Stock is entitled to one vote on all matters
submitted to a vote of stockholders. The holders of outstanding shares of Common
Stock are entitled to receive dividends out of assets legally available therefor
at such times and in such amounts as the Board of Directors may from time to
time determine. See "Dividend Policy." Holders of Common Stock have no
preemptive, conversion, redemption or sinking fund rights. Upon liquidation,
dissolution or winding up of the Company, the holders of Common Stock are
entitled to receive pro rata the assets of the Company which are legally
available for distribution, after payment of all debts and other liabilities,
subject to the prior rights of any Preferred Stock then outstanding. There is no
cumulative voting. Therefore, the holders of a majority of the shares of Common
Stock voted in an election of directors can elect all of the directors then
standing for election, subject to any rights of the holders of any then
outstanding Preferred Stock. See "Risk Factors -- Control by MLGA Fund II, L.P."
 
SERIAL PREFERRED STOCK
 
     The Board of Directors is authorized, subject to any limitations prescribed
by law, to issue preferred stock in one or more classes or series and to fix the
designations, voting powers, preferences, rights, qualifications, limitations or
restrictions of any such class or series, including dividend rights, dividend
rates, redemption prices and terms, conversion rights and liquidation
preferences of each class or series of Preferred Stock, without any further vote
or action by the stockholders of the Company. The issuance of Preferred Stock by
the Board of Directors could adversely affect the rights of holders of Common
Stock. For example, Preferred Stock could have preferences over the Common Stock
with respect to dividends and in liquidation and (upon conversion or otherwise)
also enjoy all of the rights appurtenant to the Common Stock.
 
LIMITATION OF LIABILITY; INDEMNIFICATION
 
     As permitted by the Delaware General Corporation Law (as amended from time
to time, the "DGCL"), the Amended and Restated Certificate of Incorporation
provides that directors of the Company shall not be personally liable to the
Company or its stockholders for monetary damages for breach of fiduciary duty as
a director to the fullest extent permitted by the DGCL (which currently provides
that such liability may be so limited, except for liability (i) for any breach
of the director's duty of loyalty to the Company or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of the law, (iii) under Section 174 of the DGCL, relating to
prohibited dividends or distributions or the repurchase or redemption of stock,
or (iv) for any transaction from which the director derives an improper personal
benefit).
 
     Each person who is or was a party to any action by reason of the fact that
such person is or was a director or officer of the Company shall be indemnified
and held harmless by the Company to the fullest extent permitted by the DGCL.
This right to indemnification also includes the right to have paid by the
Company the expenses incurred in connection with any such proceeding in advance
of its final disposition, to the fullest extent permitted
 
                                       33
<PAGE>   35
 
by the DGCL. In addition, the Company may, by action of the Board of Directors,
provide indemnification to such other officers, employees and agents of the
Company to such extent as the Board of Directors determines to be appropriate
under the DGCL.
 
     As a result of this provision, the Company and its stockholders may be
unable to obtain monetary damages from a director for breach of his duty of
care. Although stockholders may continue to seek injunctive or other equitable
relief for an alleged breach of fiduciary duty by a director, stockholders may
not have any effective remedy against the challenged conduct if equitable
remedies are unavailable. The Company also reserves the right to purchase and
maintain directors' and officers' liability insurance.
 
SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW
 
     The Company is subject to Section 203 of the DGCL which, subject to certain
exceptions, prohibits a Delaware corporation from engaging in a business
combination (as defined therein) with an "interested stockholder" (defined
generally as any person who beneficially owns 15% or more of the outstanding
voting stock of the Company or any person affiliated or associated with such
person) for a period of three years following the date that such stockholder
became an interested stockholder, unless (i) prior to such date the board of
directors of the corporation approved either the business combination or the
transaction that resulted in the stockholder becoming an interested stockholder;
(ii) upon consummation of the transaction that resulted in the stockholder
becoming an interested stockholder, the interested stockholder owned at least
85% of the voting stock of the corporation at the time the transaction commenced
(excluding for purposes of determining the number of shares outstanding those
shares owned (a) by directors who are also officers of the corporation and (b)
by employee stock plans in which employee participants do not have the right to
determine confidentially whether shares held subject to the plan will be
tendered in a tender or exchange offer); or (iii) on or subsequent to such date
the business combination is approved by the board of directors of the
corporation and authorized at a meeting of stockholders by the affirmative vote
of at least 66 2/3% of the outstanding voting stock of the corporation not owned
by the interested stockholder.

     The Company adopted a Rights Plan on May 29, 1998. Under the Plan, each
holder of Common Stock at the close of business on June 10, 1998 will receive a
dividend of one Right for each share of Common Stock held. Each share of Common
Stock issued after June 10, 1998 but prior to the earlier of May 29, 2008 and
the Distribution Date will be issued with a Right attached thereto. Following
the Distribution Date, each Right will be exercisable to purchase one
one-hundredth of a share of Series B Participating Cumulative Preferred Stock,
par value $0.01 per share. Once a person has become the beneficial owner of 15%
or more of the Company's Common Stock, the Rights would permit holders of Common
Stock, other than the acquiring person, to purchase additional Common Stock at a
50% discount to its then-current market price. In addition, if, after any person
has acquired such ownership, (i) the Company is involved in a merger or other
business combination in which the Company is not the surviving corporation or
its Common Stock is exchanged for other securities or assets or (ii) the Company
and/or one or more of its subsidiaries sell or otherwise transfer assets or
earning power aggregating more than 50% of the assets or earning power of the
Company and its subsidiaries taken as a whole, then each Right will entitle the
holder to purchase, for the Purchase Price, a number of shares of common stock
of the other party to such business combination or sale (or, in certain
circumstances, an affiliate) at a 50% discount to its then-current market price.
The Rights will expire on May 29, 2008, unless earlier exchanged or redeemed.
Current holders of 15% or more of the Company's Common Stock and MLGA and any of
its current or future affiliates, associates, and direct transferees are not
deemed "acquiring persons" under the Rights Plan.
    
 
TRANSFER AGENT
 
     The transfer agent and registrar for the Common Stock is ChaseMellon
Shareholder Services, L.L.C., 450 West 33rd Street, New York, NY 10001.

     McDonald & Company Securities, Inc. and SBC Warburg Dillon Read Inc. are
acting as representatives (the "Representatives") of the several Underwriters.
    
 
     The Underwriting Agreement provides that the obligation of the several
Underwriters to pay for and accept delivery of the shares of Common Stock is
subject to the approval of certain legal matters by counsel and to certain other
conditions. The Underwriters are obligated to take and pay for all shares of the
Common Stock offered hereby (other than those covered by the over-allotment
option described below) if any such shares are taken. The Underwriting Agreement
contains certain provisions whereby, if any Underwriter defaults in its
obligation to purchase such shares, and the aggregate obligations of the
Underwriters so defaulting do not exceed ten percent of the shares offered
hereby, some or all of the remaining Underwriters must assume such obligations.
 
     The Underwriters propose to offer the shares of Common Stock directly to
the public at the offering price per share set forth on the cover page hereof
and to certain dealers at a price that represents a concession not in excess of
$          per share of Common Stock under the offering price. The Underwriters
may allow, and such dealers may re-allow a concession not in excess of
$          per share to the other Underwriters or to certain other dealers. The
public offering price and the other selling terms may be changed by the
Representatives.
 
     The Company has granted to the Underwriters an option, exercisable at any
time during the 30-day period from the date of this Prospectus, to purchase up
to an aggregate of 300,000 additional shares of Common Stock at the public
offering price set forth on the cover page hereof less underwriting discounts
and commissions. The Underwriters may exercise such option to purchase
additional shares solely for the purpose of covering over-allotments, if any,
incurred in connection with the sale of the Common Stock offered hereby. To the
extent such option is exercised, each Underwriter will become obligated, subject
to certain conditions, to purchase a number of additional shares proportionate
to such Underwriter's initial amount reflected in the preceding table.
 
   
     The Company and the Selling Stockholder have agreed to indemnify the
several Underwriters against certain liabilities, including certain liabilities
under the Securities Act, or to contribute to payments the Underwriters may be
required to make in respect thereof.
    
 
   
     The Company, the Selling Stockholder and certain other stockholders of the
Company prior to the Offering have agreed, subject to certain exceptions, not to
sell, contract to sell, grant any option to sell, or otherwise dispose of,
directly or indirectly, any shares of Common Stock or securities convertible
into or exchangeable or exercisable for Common Stock or warrants or other rights
to purchase Common Stock or permit the registration of Common Stock, for a
period of 180 days from the date of this Prospectus, without the prior written
consent of McDonald & Co. Securities Inc., except for the shares of Common Stock
offered hereby.
    
 
   
     In connection with the offering, the Underwriters may purchase and sell the
Common Stock in the open market. These transactions may include over-allotment
and stabilizing transactions and purchases to cover short positions created by
the Underwriters in connection with the offering. Stabilizing transactions
consist of certain bids or purchases for the purpose of preventing or retarding
a decline in the market price of the Common Stock; and short positions created
by the Underwriters involve the sale by the Underwriters of a greater number of
shares of Common Stock than they are required to purchase from the Selling
Stockholder in the offering. The
    
 
                                       35

underwriters also may impose a penalty bid, whereby selling concessions allowed
to broker-dealers in respect of the securities sold in the offering may be
reclaimed by the Underwriters if such shares of Common Stock are repurchased by
the Underwriters in stabilizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the Common Stock,
which may be higher than the price that might otherwise prevail in the open
market; and these activities, if commenced, may be discontinued at any time.
These transactions may be effected on The Nasdaq National Market, in the
over-the-counter market or otherwise.
    
 
   
     The Underwriters have performed various investment banking services for the
Company in the past and may do so from time to time in the future. McDonald &
Company Securities, Inc. and Dillon, Read & Co. Inc., a predecessor of SBC
Warburg Dillon Read Inc., each served as a managing underwriter in the Company's
1996 IPO. Because more than 10% of the net proceeds of the Offering will be paid
to affiliates of certain members of the National Association of Securities
Dealers, Inc. ("NASD"), the Offering is being made pursuant to Rule 2710(c)(8)
of the Conduct Rules of the NASD.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Stockholders
of Gradall Industries, Inc.
 
   
     We have audited the accompanying consolidated balance sheets of Gradall
Industries, Inc. and Subsidiaries as of December 31, 1997 and 1996, and the
related consolidated statements of income, stockholders' equity and cash flows
for each of the three years in the period ended December 31, 1997. These
consolidated financial statements are the responsibility of the Company's
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 financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
   
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Gradall Industries, Inc. and Subsidiaries as of December 31, 1997 and 1996, and
the consolidated results of their operations and their cash flows for the three
years in the period ended December 31, 1997, in conformity with generally
accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                             (DOLLARS IN THOUSANDS)
 
1. NATURE OF BUSINESS AND BASIS OF PRESENTATION:
 
     Gradall Industries, Inc. (the "Company"), Incorporated in Delaware formerly
ICM Industries Inc. (ICM), is a holding company. The consolidated financial
statements include the Company and its wholly-owned subsidiaries, The Gradall
Company and Gradall Investment Company. The Gradall Investment Company was
dissolved in 1996.
 
     The Gradall Company manufacturers and sells excavating and material
handling equipment to public and private sector customers throughout the world
through independent distribution organization.
 
     On September 15, 1995, ICM entered into a Recapitalization Agreement (the
"Recapitalization" or the "Agreement"), which was effective October 13, 1995,
under which ICM (a) issued common shares comprising an 82.5% common equity
interest to MLGA Fund II, L.P. and partners for a price of $10.5 million; (b)
redeemed a portion of the common shares owned by Jack D. Rutherford and David T.
Shelby at a purchase price of $44.5 million, less costs and expenses of the
transaction, certain payments to officers and employees, amounts required to
retire existing indebtedness of The Gradall Company, and further adjusted as
required in the Agreement for working capital, income taxes,property additions
and cash balances as of the effective date of the transaction; (c) issued 140
shares of Preferred Stock with a liquidation preference of $2 million to Messrs.
Rutherford and Shelby; (d) issued common shares representing 10% of its
outstanding common stock to certain officers and employees, and (e) distributed
certain non-Gradall investments to Messrs. Rutherford and Shelby pursuant to a
plan of partial liquidation.
 
     The Recapitalization was financed under a Loan and Security Agreement with
Heller Financial, Inc. for a $10 million term loan repayable in installments
through September 30, 2000 and up to $22 million in revolving loan commitments
for a period of five years, along with a Securities Purchase Agreement with The
Marlborough Capital Investment Fund, L.P. and Mellon Ventures, Inc. for $10
million of 12.5% Senior Subordinated Notes due October 31, 2003 and warrants for
449,294 shares of common stock. These transactions were accounted for as a
leveraged recapitalization under which the existing basis of accounting was
continued, and assets and liabilities of the continuing business were carried
forward. Under the Agreement the name of ICM was changed to Gradall Industries,
Inc.
 
     Sources and uses of cash in connection with these transactions are
summarized below:

accompanying financial statements.
 
     Former wholly-owned subsidiaries of ICM, Magna Power and International
Consulting Management were transferred to Messrs. Rutherford and Shelby in
connection with the Recapitalization described above. For purposes of these
consolidated financial statements, this spin-off transaction has been treated as
a change in the reporting entity and these entities have been excluded from the
accompanying financial statements for all periods presented on the basis that
these companies operated in different industries, were autonomous and had only
incidental transactions with the Company. Management fees to these former
subsidiaries of $288 for the year ended December 31, 1995 are included in the
accompanying consolidated statements of income.
 
     The following table summarizes the October 12, 1995 book values of the

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  USE OF ESTIMATES:
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
related notes. Actual results may differ from those estimates.
 
  SOURCE OF SUPPLY OF LABOR:
 
     Virtually all of the Company's hourly employees are represented by the
International Association of Machinists and Aerospace Workers under a three-year
contract which expires April 16, 2000.
 
  REVENUE RECOGNITION:
 
     The Company's revenue recognition policy is to recognize revenue when
products are shipped.
 
  PRODUCT FINANCING:
 
     The Company provides its distributors with product financing through
agreements with third party financing companies. Such financings include a
Wholesale Floor Plan for distributors and a Retail Finance Plan for end-users,
each with reduced interest rates subsidized by the Company, and a Rental Plan
for distributors.
 
  PRODUCT WARRANTY COSTS:
 
     In general, the Company provides warranty on equipment for a period of up
to twelve months or for a specified period of use after sale or rental by the
distributor. Reserves for estimated warranty costs are established at the time
of sale.
 
  INVENTORIES:
 
     Inventories are stated at cost not in excess of market value using the
last-in, first-out (LIFO) method of inventory costing. Inventory cost includes
materials, direct labor, manufacturing overhead, and outside service costs.
Market value is determined by comparison with recent purchases or realizable
value.
 
  PROPERTY, PLANT AND EQUIPMENT:
 
     Expenditures for property, plant and equipment and for renewals and
betterments which extend the originally estimated economic lives of assets are
capitalized at cost. Expenditures for maintenance and repairs are charged to
expense. Items which are sold, retired, or otherwise disposed of are removed
from the asset and accumulated depreciation accounts and any gains or losses are
reflected in income. The Company's depreciation and amortization methods are as
follows:

  PATENTS:
 
     The cost of patents is being amortized on a straight-line basis over the
remaining legal life of the patents.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  DEFERRED FINANCING COSTS:
 
     Costs incurred to obtain financing have been capitalized and are being
amortized over the life of the respective financing arrangements.
 
  INCOME TAXES:
 
     The Company follows the provisions of Statement of Financial Accounting
Standards No. 109, "Accounting for Income Taxes". Deferred income taxes arise
from reporting certain items of income and expense for tax purposes in a
different period than for financial reporting purposes. The principle difference
relates to accounting for post-retirement health benefits.
 
  FAIR VALUE OF FINANCIAL INSTRUMENTS:
 
     The Company's financial instruments consist principally of cash, accounts
receivable, accounts payable and accrued liabilities in which the fair value of
these financial instruments approximates the carrying value. The Company's
revolving line of credit provides for periodic changes in interest rates which
approximate current rates and therefore, the fair value of the debt approximates
carrying value.
 
  RESEARCH AND DEVELOPMENT COSTS:
 
     Expenditures relating to the development of new products and processes,
including significant improvements to existing products, are expensed as
incurred. Research and development expenses were $1,722, $1,641 and $1,209 in
1997, 1996 and 1995, respectively. In addition, the Company incurred other
engineering expenses relating to new product development (that do not meet the
accounting definition of "Research and Development") in the amount of $1,922,
$1,440 and $1,295 in 1997, 1996 and 1995, respectively.
 
  STOCK BASED COMPENSATION:
 
     The Company accounts for stock based compensation awards pursuant to
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees," and its related interpretations which prescribe the use of the
intrinsic value based method. Accordingly, no compensation cost has been
recognized for its fixed stock option plans. However, the Company has adopted
the disclosure requirements of Statement of Financial Accounting Standards No.
123, "Accounting for Stock Based Compensation," See Note 10 for additional
information.
 
  PER SHARE DATA:
 
     The Company adopted Statement of Accounting Standards ("SFAS") No. 128,
"Earnings Per Share", in the fourth quarter of 1997. The impact of implementing
SFAS No. 128 is discussed in Note 14 to the Consolidated Financial Statements.
 
  RECLASSIFICATIONS:
 
     Certain 1996 and 1995 balances have been reclassified to conform to the
current year's presentation.

Revolving credit........................................  $ 9,603    $ 7,291
</TABLE>
 
     In 1996, the Company's Loan and Security Agreement with Heller Financial,
Inc. was amended and restated as of December 20, 1996. This agreement provides
for up to $25 million in revolving loan commitments. There are no aggregate
maturities on the revolving loan commitment. Amounts borrowed based on the
borrowing base, as defined, may be repaid and reborrowed at any time prior to
the earlier of a default or August 31, 1999, the termination date.
 
     The revolving line of credit bears interest at either LIBOR plus 1% or
prime minus .50%. At December 31, 1997, the prime rate was 8.5%, LIBOR was
5.97%, and the average annual interest rate in effect for the revolving line of
credit was 7.86%. At December 31, 1996, the prime rate was 8.25%, LIBOR was
5.66%, and the average annual interest rate in effect for the revolving line of
credit was 9.94%. The Company also pays an unused line fee of 0.25 percent per
annum.
 
     The terms of the financing agreement contain, among other provisions,
restrictions on the level of capital expenditures and various financial ratios,
as defined. The financing agreements are collateralized by substantially all the
assets of the Company.

6. LEASE OBLIGATIONS:
 
     The Company leases certain machinery and equipment under capital leases
expiring beginning in the year 1998. The assets and liabilities under capital
leases are recorded at the original purchase cost. The assets are depreciated
over their estimated productive lives. Depreciation of assets under capital
leases is included in depreciation expense.
 
     In addition, the Company leases certain equipment under operating leases
having terms up to 5 years which are for equipment. A number of these leases
have renewal options.
 
     The following is a summary of property held under capital leases:

7. EMPLOYEE BENEFIT PLANS:
 
  PENSION PLANS:
 
     Substantially all employees are covered by pension plans which provide for
monthly pension payments to eligible former employees who have retired. Prior to
March 24, 1997 the Company sponsored two plans, one for members of the
collective bargaining unit and one for salaried and other eligible employees.
 
     Benefits paid under the collective bargaining unit plan are based on a
benefit multiplier times years of credited service, reduced by benefits under a
prior plan. Such prior plan benefits are guaranteed under the terms of group
annuity contracts. Benefits paid under the salary plan are based on the greater
of a benefit multiplier times years of credited service or a percentage of
pre-retirement earnings. Pension costs are funded as actuarially

determined and to the extent cash contributions are deductible for federal
income tax purposes. The collective bargaining unit plan uses the entry age
normal actuarial cost method to determine annual contributions to the plan. The
salary plan uses the unit credit actuarial cost method to determine
contributions.
 
     Effective March 24, 1997 the Company adopted the IAM National Pension Plan
to replace the existing collective bargaining unit plan for future service
benefits. The collective bargaining unit plan benefits were frozen and the
Company continues to fund the plan for past service benefits. The expense
related to funding the IAM National Pension Plan from March 24, 1997 to December
31, 1997 was $254.
 
     The components of net periodic pension cost for the years ended December
31, 1997, 1996 and 1995 are as follows:

     Statement of Financial Accounting Standards No. 87 contains a provision
which requires the recognition of a liability (including unfunded accrued
pension costs) that is at least equal to the unfunded accumulated benefit
obligation (the excess of the accumulated benefit obligation over the fair value
of plan assets). Recognition of an

7. EMPLOYEE BENEFIT PLANS: (CONTINUED)
additional minimum liability is required if an unfunded accumulated benefit
exists and the liability already recognized as unfunded accrued pension cost is
less than the unfunded accumulated benefit obligation. The additional minimum
liability of $980 and $1,171 at December 31, 1997 and 1996, respectively, has
been included in other long-term liabilities and an intangible pension asset of
$17 at December 31, 1996 has been recorded in an amount not exceeding the amount
of unrecognized prior service cost. The difference between the long-term
liabilities and the intangible asset has been reported net of income tax effect
within equity.
 
  SAVINGS AND INVESTMENT PLAN:
 
     Substantially all employees are eligible to participate in a savings and
investment plan. The Company sponsors two plans, one for members of the
collective bargaining unit and one for salaried and other eligible employees.
The plans provide for contributions by employees, through salary reductions, and
for a matching contribution by the Company based on a rate determined for each
plan year by the Board of Directors of the Company. The plans also provide for a
discretionary contribution by the Company.
 
  DEFERRED COMPENSATION PROGRAM:
 
     The Company has a deferred compensation program under which certain
employees may elect to postpone receipt of a portion of their earnings. The
amounts so deferred are deposited in a trust account, but remain assets of the
Company. The trustees of the program are officers and a key employee of the
Company.
 
  PROFIT SHARING PLAN:
 
     The Company maintains a profit sharing plan covering union and salaried
employees. The amount of the profit sharing bonus is determined by the Company's
return on sales and is calculated based upon the wages of eligible employees.
 
  POST-RETIREMENT BENEFITS:
 
     The Company provides eligible retired employees with health care and life
insurance benefits. These benefits are provided on a non-contributory basis for
life insurance and contributory basis for medical coverage. Currently, the
Company does not pre-fund these benefits.
 
     The components of periodic net post-retirement benefit cost for the years
ended December 31, 1997, 1996 and 1995 are as follows:

</TABLE>
 
     For measuring the expected Post-Retirement Benefit Obligation, an 8% annual
rate increase in the per capita cost of covered health care benefits was assumed
for 1997. This rate was assumed to decrease to 5.0% by 2011 and remain constant
thereafter. The weighted average discount rate used in determining the
Accumulated Post-retirement Benefit Obligation was 7.0% and 7.5% respectively at
December 31, 1997 and 1996.
 
     If the health care cost trend rate were increased 1%, the Accumulated
Post-Retirement Obligation as of December 31, 1997 would have increased by
$2,627 and the effect of this change on the aggregate of service and interest
costs for 1997 would be an increase of $157 and $155, respectively.

10. STOCK OPTIONS:
 
     On October 13, 1995, the stockholders approved a qualified incentive stock
option program under which 315,226 shares of the Company's common stock are
reserved for grants to key employees (The "1995 Stock Option Plan"). The option
price is to be determined by the Board, but may not be less than 100% of the

     On August 15, 1996, an unqualified stock option for 10,000 shares of common
stock was granted to a director at the exercise price of $2.71.
 
     In October 1995, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation." This statement defines a fair value based method of accounting
for an employee stock option or similar equity instrument. The statement does,
however, allow an entity to continue to measure compensation cost for those
plans using the intrinsic value based method of accounting prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued To
Employees."
 
     In 1996, the Company adopted provisions of SFAS No. 123 by providing
disclosures of the pro forma effect on net income and earnings per share that
would result if the fair value compensation element were to be

13. EXTRAORDINARY ITEM:
 
     The early repayment of the term debt and subordinated debt with the
proceeds of the initial public offering resulted in the write-off of $723 of
deferred financing costs and unamortized discount on the subordinated debt of
$872 which have been accounted for as an extraordinary charge resulting from
early extinguishment of debt net of applicable income taxes of $622. Total
income before taxes after consideration of these extraordinary expenses amounted
to $12,194 for the year ended December 31, 1996.

14. EARNINGS PER SHARE:
 
     In the fourth quarter of 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings per Share", which modifies the
calculation of earnings per share. The Standard replaces the previous
presentation of primary and fully diluted earnings per share to basic and
diluted earnings per share.
 
     Basic earnings per share excludes dilution and is computed by dividing
income by the weighted average number of common shares outstanding for the
period. Diluted earnings per share includes the dilution of common stock
equivalents, and is computed similarly to fully diluted earnings per share
pursuant to Accounting Principals Board Opinion 15. All prior periods presented
have been restated to reflect this adoption.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the Delaware General Corporation Law, as amended, provides
with regard to indemnification of directors and officers as follows:
 
          145. Indemnification of Officers, Directors, Employees and Agents;
     Insurance. (a) A corporation may indemnify any person who was or is a party
     or is threatened to be made a party to any threatened, pending or completed
     action, suit or proceeding, whether civil, criminal, administrative or
     investigative (other than an action by or in the right of the corporation)
     by reason of the fact that he is or was a director, officer, employee or
     agent of the corporation, or is or was serving at the request of the
     corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise, against
     expenses (including attorneys' fees), judgments, fines and amounts paid in
     settlement actually and reasonably incurred by him in connection with such
     action, suit or proceeding if he acted in good faith and in a manner he
     reasonably believed to be in or not opposed to the best interests of the
     corporation, and, with respect to any criminal action or proceeding, had no
     reasonable cause to believe his conduct was unlawful. The termination of
     any action, suit or proceeding by judgment, order, settlement, conviction,
     or upon a plea of nolo contendere or its equivalent, shall not, of itself,
     create a presumption that the person did not act in good faith and in a
     manner which he reasonably believed to be in or not opposed to the best
     interests of the corporation, and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that his conduct was unlawful.
 
          (b) A corporation may indemnify any person who was or is a party or is
     threatened to be made a party to any threatened, pending or completed
     action or suit by or in the right of the corporation to procure a judgment
     in its favor by reason of the fact that he is or was a director, officer,
     employee or agent of the corporation, or is or was serving at the request
     of the corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     expenses (including attorneys' fees) actually and reasonably incurred by
     him in connection with the defense or settlement of such action or suit if
     he acted in good faith and in a manner he reasonably believed to be in or
     not opposed to the best interests of the corporation and except that no
     indemnification shall be made in respect of any claim, issue or matter as
     to which such person shall have been adjudged to be liable to the
     corporation unless and only to the extent that the Court of Chancery or the
     court in which such action or suit was brought shall determine upon
     application that, despite the adjudication of liability but in view of all
     the circumstances of
 
                                      II-1
<PAGE>   66
 
     the case, such person is fairly and reasonably entitled to indemnity for
     such expenses which the Court of Chancery or such other court shall deem
     proper.
 
          (c) To the extent that a director, officer, employee or agent of a
     corporation has been successful on the merits or otherwise in defense of
     any action, suit or proceeding referred to in subsections (a) and (b) of
     this section, or in defense of any claim, issue or matter therein, he shall
     be indemnified against expenses (including attorneys' fees) actually and
     reasonably incurred by him in connection therewith.
 
          (d) Any indemnification under subsections (a) and (b) of this section
     (unless ordered by a court) shall be made by the corporation only as
     authorized in the specific case upon a determination that indemnification
     of the director, officer, employee or agent is proper in the circumstances
     because he has met the applicable standard of conduct set forth in
     subsections (a) and (b) of this section. Such determination shall be made
     (1) by a majority vote of the directors who are not parties to such action,
     suit or proceeding, even though less than a quorum, or (2) if there are no
     such directors, or if such directors so direct, by independent legal
     counsel in a written opinion, or (3) by the stockholders.
 
          (e) Expenses (including attorneys' fees) incurred by an officer or
     director in defending any civil, criminal, administrative or investigative
     action, suit or proceeding may be paid by the corporation in advance of the
     final disposition of such action, suit or proceeding upon receipt of an
     undertaking by or on behalf of such director or officer to repay such
     amount if it shall ultimately be determined that he is not entitled to be
     indemnified by the corporation as authorized in this section. Such expenses
     (including attorneys' fees) incurred by other employees and agents may be
     so paid upon such terms and conditions, if any, as the board of directors
     deems appropriate.
 
          (f) The indemnification and advancement of expenses provided by, or
     granted pursuant to, the other subsections of this section shall not be
     deemed exclusive of any other rights to which those seeking indemnification
     or advancement of expenses may be entitled under any bylaw, agreement, vote
     of stockholders or disinterested directors or otherwise, both as to action
     in his official capacity and as to action in another capacity while holding
     such office.
 
          (g) A corporation shall have power to purchase and maintain insurance
     on behalf of any person who is or was a director, officer, employee or
     agent of the corporation, or is or was serving at the request of the
     corporation as a director, officer, employee or agent of another
     corporation, partnership, joint venture, trust or other enterprise against
     any liability asserted against him and incurred by him in any such
     capacity, or arising out of his status as such, whether or not the
     corporation would have the power to indemnify him against such liability
     under this section.
 
          (h) For purposes of this section, references to "the corporation"
     shall include, in addition to the resulting corporation, any constituent
     corporation (including any constituent of a constituent) absorbed in a
     consolidation or merger which, if its separate existence had continued,
     would have had power and authority to indemnify its directors, officers,
     and employees or agents, so that any person who is or was a director,
     officer, employee or agent of such constituent corporation, or is or was
     serving at the request of such constituent corporation as a director,
     officer, employee or agent of another corporation, partnership, joint
     venture, trust or other enterprise, shall stand in the same position under
     this section with respect to the resulting or surviving corporation as he
     would have with respect to such constituent corporation if its separate
     existence had continued.
 
          (i) For purposes of this section, references to "other enterprises"
     shall include employee benefit plans; references to "fines" shall include
     any excise taxes assessed on a person with respect to any employee benefit
     plan; and references to "serving at the request of the corporation" shall
     include any service as a director, officer, employee or agent of the
     corporation which imposes duties on, or involves services by, such
     director, officer, employee, or agent with respect to an employee benefit
     plan, its participants or beneficiaries; and a person who acted in good
     faith and in a manner he reasonably believed to be in the interest of the
     participants and beneficiaries of an employee benefit plan shall be deemed
     to have acted in a manner "not opposed to the best interests of the
     corporation" as referred to in this section.
 
                                      II-2
<PAGE>   67
 
          (j) The indemnification and advancement of expenses provided by, or
     granted pursuant to, this section shall, unless otherwise provided when
     authorized or ratified, continue as to a person who has ceased to be a
     director, officer, employee or agent and shall inure to the benefit of the
     heirs, executors and administrators of such a person.
 
          (k) The Court of Chancery is hereby vested with exclusive jurisdiction
     to hear and determine all actions for advancement of expenses or
     indemnification brought under this section or under any bylaw, agreement,
     vote of stockholders or disinterested directors, or otherwise. The Court of
     Chancery may summarily determine a corporation's obligation to advance
     expenses (including attorneys' fees).
 
     Section 102(b)(7) of the Delaware General Corporation Law, as amended,
provides in regard to the limitation of liability of directors and officers as
follows:
 
          (b) In addition to the matters required to be set forth in the
     certificate of incorporation by subsection (a) of this section, the
     certificate of incorporation may also contain any or all of the following
     matters:
 
                                     * * *
 
          (7) A provision eliminating or limiting the personal liability of a
     director to the corporation or its stockholders for monetary damages for
     breach of fiduciary duty as a director, provided that such provision shall
     not eliminate or limit the liability of a director: (i) for any breach of
     the director's duty of loyalty to the corporation or its stockholders, (ii)
     for acts or omissions not in good faith or which involve intentional
     misconduct or a knowing violation of law, (iii) under section 174 of this
     title; or (iv) for any transaction from which the director derived an
     improper personal benefit. No such provision shall eliminate or limit the
     liability of a director for any act or omission occurring prior to the date
     when such provision becomes effective. All references in this paragraph to
     a director shall also be deemed to refer (x) to a member of the governing
     body of a corporation which is not authorized to issue capital stock, and
     (y) to such other person or persons, if any, who, pursuant to a provision
     of the certificate of incorporation in accordance with sec.141(a) of this
     title, exercise or perform any of the powers or duties otherwise conferred
     or imposed upon the board of directors by this title.
 
     Article Seventh of the Certificate of Incorporation of the Company provides
with regard to indemnification of directors and officers as follows:
 
          SEVENTH: The Corporation shall, to the full extent permitted by
     Section 145 of the Delaware General Corporation Law, as amended from time
     to time, indemnify all persons whom it may indemnify pursuant thereto.
 
ITEM 16. EXHIBITS.
 
     The list of exhibits is incorporated herein by reference to the Index to
Exhibits on page E-1.
 
ITEM 17. UNDERTAKINGS.
 
     The undersigned registrant hereby undertakes that:
 
          (1) The undersigned registrant hereby undertakes to provide to the
     underwriter at the closing specified in the underwriting agreements,
     certificates in such denominations and registered in such names as required
     by the underwriter to permit prompt delivery to each purchaser.
 
          (2) Insofar as indemnification for liabilities arising under the
     Securities Act may be permitted to directors, officers and controlling
     persons of the Company pursuant to the foregoing provisions, or otherwise,
     the Company has been advised that in the opinion of the Securities and
     Exchange Commission such indemnification is against public policy as
     expressed in the Securities Act and is, therefore, unenforceable. In the
     event that a claim for indemnification against such liabilities (other than
     the payment by the Company of expenses incurred or paid by a director,
     officer or controlling person of the Company in the successful defense of
     any action, suit or proceeding) is asserted by such director, officer or
     controlling person in connection with the securities being registered, the
     Company will, unless in the opinion of its counsel the matter has been
     settled by controlling precedent, submit to a court of appropriate
     jurisdiction the
                                      II-3
<PAGE>   68
 
     question whether such indemnification by it is against public policy as
     expressed in the Securities Act and will be governed by the final
     adjudication of such issue.
 
          (3) For purposes of determining any liability under the Securities Act
     of 1933, the information omitted from the form of prospectus filed as part
     of this registration statement in reliance upon Rule 430A and contained in
     a form of prospectus filed by the Company pursuant to Rule 424(b)(1) or (4)
     or 497(h) under the Securities Act shall be deemed to be part of this
     registration statement as of the time it was declared effective.
 
          (4) For the purpose of determining any liability under the Securities
     Act of 1933, each post-effective amendment that contains a form of
     prospectus shall be deemed to be a new registration statement relating to
     the securities offered therein, and the offering of such securities at that
     time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:


         Reference is made to your Registration Statement on Form S-3 (File No.
33-55763) filed with the Securities and Exchange Commission with respect to the
proposed sale of up to 2,300,000 shares (the "Shares") of Common Stock, par
value $.001, of Gradall Industries, Inc. (the "Company") of which 1,500,000
shares are to be sold by MGLA Fund II (the "Selling Stockholder") and the
balance are to be sold by the Company.

         We have examined the records relating to the incorporation of the
Company, including its Certificate of Incorporation and all amendments thereto,
the records of proceedings taken by its directors and shareholders to date and
the applicable provisions of the laws of the State of Delaware under which the
Company was incorporated.

         Based upon the foregoing and upon the examination of such other matters
as we have deemed necessary in order to express the opinions hereafter set
forth, we are of the opinion that:

         1.   The Shares to be issued and sold by the Company pursuant to the
              Registration Statement have been duly authorized and, when issued
              and sold upon the terms described in said Registration Statement,
              will be validly issued, fully paid and nonassessable.

         2.   The Shares to be sold by the Selling Stockholder pursuant to the
              Registration Statement have been duly authorized, validly issued
              and are fully paid and nonassessable.

         We consent to the filing of this opinion as an exhibit to said
Registration Statement and to the reference to us in the prospectus included
therein under the caption "Legal Matters." In giving such consent, we do not
admit that we are within the category of persons whose consent is required under
Section 7 of the Securities Act of 1933, as amended, or the rules and
regulations promulgated thereunder.


                                       Very truly yours,

                                       /s/ Black, McCuskey, Souers & Arbaugh
