JLG INDUSTRIES, INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
JANUARY 31, 2000
(in thousands, except per share data)
(Unaudited)


BASIS OF PRESENTATION
The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to Form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all information and notes
required by generally accepted accounting principles for complete financial
statements. In the opinion of management, all adjustments (consisting of normal
recurring accruals) considered necessary for a fair presentation have been
included.

Operating results for the three and six month periods ended January 31, 2000 are
not necessarily indicative of the results that may be expected for the fiscal
year as a whole. For further information, refer to consolidated financial
statements and notes included in the Company's annual report on Form 10-K for
the fiscal year ended July 31, 1999.

INVENTORIES AND COST OF SALES
A precise inventory valuation under the LIFO (last-in, first-out) method can
only be made at the end of each fiscal year; therefore, interim LIFO inventory
valuation determinations, including the determination at January 31, 2000, must
necessarily be based on management's estimate of expected fiscal year-end
inventory levels and costs.

The components of inventory at the end of the each period consisted of the
following:

Options to purchase 1,111 shares of common stock at a range of $13.69 to $21.94
were outstanding during the second quarter of fiscal 2000. However these shares
were not included in the computation of diluted earnings per share because the
options' exercise price was greater than the average market price of the common
shares.

COMMITMENTS AND CONTINGENCIES
The Company is a party to personal injury and property damage litigation arising
out of incidents involving the use of its products. The Company's insurance
program for fiscal year 2000 is comprised of a self-insured retention of $7
million for domestic claims, insurance coverage of $2 million for international
claims and catastrophic coverage for domestic and international claims of $75
million in excess of the retention and international primary coverage. The
Company contracts with an independent firm to provide claims handling and
adjustment services. The Company's estimates with respect to claims are based on
internal evaluations of the merits of individual claims and the reserves
assigned by the Company's independent firm. The methods of making such estimates
and establishing the resulting accrued liability are reviewed frequently, and
any adjustments resulting therefrom are reflected in current earnings. Claims
are paid over varying periods, which generally do not exceed five years. Accrued
liabilities for future claims are not discounted.

With respect to all product liability claims of which the Company is aware,
accrued liabilities of $13.3 million and $14.1 million were established at
January 31, 2000 and July 31, 1999, respectively. While the Company's ultimate
liability may exceed or be less than the amounts accrued, the Company believes
that it is unlikely that it would experience losses that are materially in
excess of such reserve amounts.

<PAGE>   8
As of January 31, 2000 and July 31, 1999, there were no insurance recoverables
or offset implications and there were no claims by the Company being contested
by insurers.

SEGMENT INFORMATION
The Company operates in two reportable business segments - machinery, which
consists of the design, manufacture and sale of new equipment; and customer
services and support, which consists of after-sales service and support,
including parts sales, equipment rentals, used equipment sales and rebuilding
used equipment. The Company evaluates the performance of its reportable segments
based upon a number of factors including segment profit. Segment profit excludes
interest, miscellaneous income/expense and income taxes. Intersegment sales and
transfers are accounted for at cost and are not significant.

The following table provides business segment information for each of the
periods ended January 31:

BANK CREDIT LINES AND LONG-TERM DEBT
The Company has credit agreements with a group of financial institutions that
provides for an unsecured revolving credit facility expiring June 2004 with an
aggregate commitment of $350 million. During the quarter, the Company increased
its revolving credit facility to $350 million from $250 million. Borrowings
under the agreements bear interest equal to either LIBOR plus a margin ranging
from 0.55 percent to 1.125 percent, depending on the Company's ratio of funded
debt to EBITDA; or the greater of prime or federal funds rate plus 0.50 percent.
The Company is required to pay an annual administrative fee of $35 and a
facility fee ranging from 0.20 percent to 0.275 percent, depending on the
Company's ratio of funded debt to EBITDA. The agreements contains customary
affirmative and negative covenants including financial covenants requiring the
maintenance of specified consolidated interest coverage, leverage ratios and a
minimum net worth. The Company also has available a $20 million unsecured bank
revolving line of credit with a term of one year, renewable annually, and at an
interest rate of prime or a spread over LIBOR. The Company also has $2.5 million
in loan facilities with a term of one year, renewable annually, and at a fixed
weighted average interest rate of 5.7 percent.

RESULTS FOR THE SECOND QUARTERS OF FISCAL 2000 AND 1999
Sales for the second fiscal quarter ended January 31, 2000 were $206.9 million,
up $68.7 million or 50 percent from the $138.2 million reported in the year-ago
period. Growth of the aerial work platform product group accounted for $27.8
million, or 41 percent of the revenue increase, while telescopic material
handling and excavator products, acquired in June 1999, represented $40.9
million, or 59 percent of the increase. Domestic sales for the second quarter of
fiscal 2000 were $148.9, up 59 percent from the fiscal 1999 second quarter sales
of $93.5 million. International sales were $58.0 million, up 30 percent from the
comparable year-ago quarter. Customer Service and Support sales for the second
fiscal quarter were $29.1 million, up $10.1 million or 53 percent compared to
prior year quarter.

The gross profit percentage for the quarter was 18.7 percent, down 4.1
percentage points from the year-ago quarter. As a result of the Company's cost
reduction efforts, the gross profit percentage was favorably impacted by lower
product costs but more than offset by the following factors: a less favorable
product mix; the impact of aggressive acceptance of trade-ins to displace
competitor products during the quarter; competitive price pressures; strength of
the U.S. dollar against foreign currencies, primarily the Euro; and start-up
costs for the Shippensburg and Orrville plants.

The $10.0 million increase in selling, administrative and product development
costs compared to the 1999 second fiscal quarter was principally due to the
Gradall acquisition and the expansion of the Company's sales and service
capabilities globally. At 12.7 percent of sales, these expenses were nine tenths
of a percent above the percentage for the year ago quarter.

The current year quarter includes $1.5 million in goodwill amortization
primarily due to the Gradall acquisition. The increase in interest charges of
$5.4 million was due to an increase in average borrowings to fund the Gradall
acquisition and working capital investments.

The effective tax rate of 37 percent was more than nine percentage points higher
in the fiscal 2000 second quarter compared to the year-ago period. This increase
was primarily due to goodwill charges not being tax deductible and a one-time
benefit attributable to certain tax incentives related to export sales in the
fiscal 1999 second quarter.

RESULTS FOR THE FIRST SIX MONTHS OF FISCAL 2000 AND 1999
For the six-month period ended January 31, 2000, sales were $424.9 million, up
$158.0 million, or 59 percent, from the $266.9 million reported in the year-ago
period. Growth of the aerial work platform product group accounted for $79.9
million, or 51 percent of the revenue increase, while telescopic material
handling and excavator products represented $78.1 million, or 49 percent of the
increase. Domestic sales for the six months of fiscal 2000 were $311.9, up 69
percent from the fiscal 1999 six

                                       7

months sales of $184.2 million. International sales were $113.0 million, up 37
percent from the comparable year-ago period. Customer Service and Support sales
for the six-month period were $65.0 million, up $29.2 million or 81 percent
compared to prior year period.

Gross profit percentage for the six months of fiscal 2000 was 21.5 percent, down
1.4 percentage points from the year-ago period. The decrease was mainly due to
the same factors as discussed in the second quarter comparison.

Selling, administrative and product development costs increased $22.0 million
from the comparable year-ago six months. The increase was mainly due to the same
factors as discussed in the second quarter comparison. At 12.5 percent of sales,
these expenses were eight tenths of a percent above the percentage for the year
ago quarter.

The current year period includes $3.1 million in goodwill amortization and an
increase in interest charges of $8.8 million, primarily due to the same factors
as discussed in the second quarter comparison.

The effective tax rate of 37 percent was six percentage points higher in the
fiscal 2000 six-month period compared to the year-ago period. This increase was
primarily due to the same factors as discussed in the second quarter comparison.

FINANCIAL CONDITION
Cash used for operations increased to $88.6 million in the first six months of
fiscal 2000 from $25.4 million used for operations in the comparable period of
1999. The increase in cash used for operations in fiscal 2000 compared to fiscal
1999 was primarily due to a $119.9 million change in operating assets and
liabilities principally reflecting higher receivable and inventory levels.
Receivables were higher in dollar terms and days sales outstanding due to
expanded use of extended payment terms. The increase in inventory is due to the
Company's decision to maintain relatively constant production levels in
anticipation of the high level of demand corresponding to the prime buying
season of the Company's customers, and a more pronounced than anticipated
deferral of purchases by certain major North American rental customers into the
2000 calendar year.

Cash used for investing activities during the first six months of fiscal 2000
was $1.1 million compared to $14.9 million for last year's comparable period.
The decrease relates primarily to sales of equipment held for rental which
occurred in fiscal year 2000. Partially offsetting the decrease in cash used for
investing activities were capital expenditures for the Shippensburg,
Pennsylvania and Orrville, Ohio facilities.

At January 31, 2000, the Company had unused credit lines totaling $121 million.
The Company believes that its credit lines, coupled with cash expected to be
generated by operations, to be sufficient to fund its ongoing operations,
capital-related projects for fiscal 2000 and its plan to purchase on the open
market up to five million shares of its common stock. These share purchases may
begin immediately after lender approvals are received, which are expected
shortly, and may occur, from time to time, during the twelve month period
commencing on February 16, 2000. Capital expenditures are expected to consist of
capital projects primarily for the Shippensburg, Pennsylvania and Orrville, Ohio
facilities.

Cash provided from financing activities was $79.1 million for the first six
months of fiscal 2000 compared to $106 thousand provided for the comparable
period of fiscal 1999. Increased borrowings under the existing revolving credit
agreements were used for business expansion as discussed above.

The Company's exposure to product liability claims is discussed in the note
entitled Commitments and Contingencies of the Notes to Consolidated Financial
Statements of this report. Future results of operations, financial condition and
liquidity may be affected to the extent that the Company's ultimate exposure
with respect to product liability varies from current estimates.

OUTLOOK
This Outlook section and other parts of this Management's Discussion and
Analysis contain forward-looking information and involve certain risks and
uncertainties that could significantly impact expected results. Certain
important factors that, in some cases have affected, and in the future could
affect, the Company's results of operations and that could cause such future
results of operations to differ materially are described in "Cautionary
Statements Pursuant to the Securities Litigation Reform Act" which is an exhibit
to this report.

Most of the factors which detracted from profits in the second quarter are
reversible, and management is aggressively addressing each of these. Further,
management is confident in the overall health of the aerial work platform and
excavator marketplaces and is encouraged with the opportunity to expand sales of
material handler products. Management will continue to focus on growing the
business by maintaining its leadership positions in these product categories,
and by so doing, enhancing its profitability and the value it creates for
shareholders.

To combat the current pricing environment and improve gross profit margins,
management is placing increased emphasis on improving manufacturing efficiencies
and reducing costs. These efforts are taking place on several fronts, including
an accelerated focus on Gradall operations. Start-up costs at the Company's
Orrville and Shippensburg facilities will be eliminated as management brings
these two new plants fully on line by the end of this calendar year. When fully
operational, management expects to begin realizing the positive cost reduction
benefits they provide. Although the Company continues to pursue its trade-in
strategy, management expects the impact on margins from this activity to lessen
during the second half of the fiscal year. Management also expects the Company's
product mix to be more favorable in the second half of 2000.

On January 18, 2000, the Company forecast sales to be approximately $1.0 billion
and earnings per share to be in the $1.20 to $1.25 range and on February 17th,
the Company announced that it expected to meet or exceed the sales and earnings
forecasts previously announced in January.

IMPACT OF YEAR 2000
The year 2000 issue arose out of the fact that many computer programs were
written using two digits to identify the applicable year rather than four
digits. It was feared that computer programs with date-sensitive software or
equipment with embedded date-sensitive technology might misinterpret a two-digit
year code. This error could result in system or equipment failures or
miscalculations and disruptions of operations. As of December 31, 1999, the
Company had completed all aspects of its year 2000 readiness program and,
through February 17, 2000, the Company has not experienced any significant
problems related to the Y2K issue.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The Company is exposed to market risk from changes in interest rates and foreign
currency exchange rates, which could affect its future results of operations and
financial condition. The Company manages exposure to these risks principally
through its regular operating and financing activities.

                                       9
<PAGE>   12
While the Company is exposed to changes in interest rates as a result of its
outstanding debt, the Company does not currently utilize any derivative
financial instruments related to its interest rate exposure. Total short-term
and long-term debt outstanding at January 31, 2000 was $254.7 million,
consisting of $249.0 million in variable rate borrowing and $5.7 million in
fixed rate borrowing. At the current level of variable rate borrowing, a
hypothetical 10 percent increase in interest rates would decrease pre-tax
current year earnings by approximately $1.7 million on an annual basis. A
hypothetical 10 percent change in interest rates would not result in a material
change in the fair value of the Company's fixed rate debt. The Company does not
have a material exposure to financial risk from using derivative financial
instruments to manage its foreign currency exposures. For additional
information, reference is made to Item 7 in the Company's annual report on Form
10-K for the fiscal year ended July 31, 1999.

Independent Accountants' Review Report

The Board of Directors
JLG Industries, Inc.

We have reviewed the accompanying condensed consolidated balance sheet of JLG
Industries, Inc. and subsidiaries as of January 31, 2000, and the related
condensed consolidated statements of income for the three month periods ended
January 31, 2000 and 1999 and the condensed consolidated statements of cash
flows for the six-month periods ended January 31, 2000 and 1999. These financial
statements are the responsibility of the Company's management.

We conducted our reviews in accordance with standards established by the
American Institute of Certified Public Accountants. A review of interim
financial information consists principally of applying analytical procedures to
financial data, and making inquiries of persons responsible for financial and
accounting matters. It is substantially less in scope than an audit conducted in
accordance with auditing standards generally accepted in the United States,
which will be performed for the full year with the objective of expressing an
opinion regarding the financial statements taken as a whole. Accordingly, we do
not express such an opinion.

Based on our reviews, we are not aware of any material modifications that should
be made to the accompanying financial statements referred to above for them to
be in conformity with accounting principles generally accepted in the United
States.

We have previously audited, in accordance with auditing standards generally
accepted in the United States, the consolidated balance sheet of JLG Industries,
Inc. as of July 31, 1999, and the related consolidated statements of income,
shareholders' equity, and cash flows for the year then ended (not presented
herein), and in our report dated September 9, 1999, we expressed an unqualified
opinion on those consolidated financial statements. In our opinion, the
information set forth in the accompanying condensed consolidated balance sheet
as of July 31, 1999, is fairly stated, in all material respects, in relation to
the consolidated balance sheet from which it has been derived.

         Section 2.1. Loans.

             Subject to the terms and conditions of this Agreement, each Lender
severally agrees to make Loans to the Borrowers from time to time from the
Closing Date through the Termination Date as requested by the Borrowers in
accordance with the terms of Section 2.2; provided, that (a) the aggregate
principal amount of all outstanding Loans (after giving effect to any amount
requested) shall not exceed the Aggregate Commitment and (b) the principal
amount of outstanding Loans from any Lender to the Borrowers shall not at any
time exceed such Lender's Commitment. Each Loan by a Lender shall be in a
principal amount equal to such Lender's Commitment Percentage of the aggregate
principal amount of Loans requested on such occasion. Subject to the terms and
conditions hereof, the Borrowers may borrow, repay and reborrow Loans hereunder
until the Termination Date. The obligations of Borrowers under the Loans are and
shall be joint and several.

         Section 2.2. Procedure for Advances of Loans.

             (a) Requests for Borrowing. JLG, on behalf of the Borrowers, shall
give the Administrative Agent irrevocable prior written notice in the form
attached hereto as Exhibit B (a "Notice of Borrowing") not later than 11:00 a.m.
(Philadelphia time) (i) on the same Business Day as each Base Rate Loan and (ii)
on the third (3rd) Business Day before each LIBOR Rate Loan of its intention to
borrow, specifying (A) the date of such borrowing, which shall be a Business
Day, (B) the amount of such borrowing, which shall be in an amount equal to the
amount of the Aggregate Commitment then available to the Borrowers, or if less,
(x) with respect to Base Rate Loans in an aggregate principal amount of
$1,000,000 or a whole multiple of $250,000 in excess thereof and (y) with
respect to LIBOR Rate Loans in an aggregate principal amount of $3,000,000 or a
whole multiple of $1,000,000 in excess thereof, (C) whether such Loans are to be
LIBOR Rate Loans or Base Rate Loans, and (D) in the case of a LIBOR Rate Loan,
the duration of the Interest Period applicable thereto. Notices received after
11:00 a.m. (Philadelphia time) shall be deemed received on the next Business
Day. The Administrative Agent shall promptly notify the Lenders of each Notice
of Borrowing.

             (b) Authority of JLG. Each of the Borrowers hereby irrevocably
authorizes and requests that JLG execute all Notices of Borrowing, make all
elections as to interest rates and take any other actions required of or
permitted by the Borrowers under this Agreement, on its respective behalf, in
each case with the same force and effect as if such Borrower had executed such
Notice of Borrowing, made such election or taken such other action

                                       14

itself. Any request, application or other communication by JLG may be relied on
by the Administrative Agent and the Lenders, and any communication by the
Administrative Agent and Lenders shall be made to JLG, and shall be binding on
each Borrower, jointly and severally, as fully as if such request, application
or other communication were made directly by or to each such Borrower.

             (c) Disbursement of Loans. Not later than 2:00 p.m. (Philadelphia
time) on the proposed borrowing date, each Lender will make available to the
Administrative Agent, for the account of the Borrowers, at the office of the
Administrative Agent in funds immediately available to the Administrative Agent,
such Lender's Commitment Percentage of the Loans to be made on such borrowing
date. The Borrowers hereby irrevocably authorize the Administrative Agent to
disburse the proceeds of each borrowing requested pursuant to this Section 2.2
in immediately available funds by crediting or wiring such proceeds to the
deposit account of the Borrowers identified in the most recent notice
substantially in the form of Exhibit C hereto (a "Notice of Account
Designation") delivered by the Borrowers to the Administrative Agent or as may
be otherwise agreed upon by the Borrowers and the Administrative Agent from time
to time. Subject to Section 3.7 hereof, the Administrative Agent shall not be
obligated to disburse the portion of the proceeds of any Loan requested pursuant
to this Section 2.2 to the extent that any Lender has not made available to the
Administrative Agent its Commitment Percentage of such Loan.

         Section 2.3. Repayment of Loans.

             (a) Repayment on Termination Date. The Borrowers shall repay the
outstanding principal amount of all Loans in full on the Termination Date,
together with all accrued but unpaid interest thereon.

             (b) Mandatory Repayment of Excess Loans. If at any time the
outstanding principal amount of all Loans exceeds the Aggregate Commitment, the
Borrowers shall repay immediately upon notice from the Administrative Agent, by
payment to the Administrative Agent for the account of the Lenders, Loans in an
amount equal to such excess with such repayment applied first to the principal
amount of outstanding Loans. Each such repayment shall be accompanied by any
amount required to be paid pursuant to Section 3.9 hereof.

             (c) Optional Repayments. The Borrowers may at any time and from
time to time repay the Loans, in whole or in part, upon at least three (3)
Business Days irrevocable notice to the Administrative Agent with respect to
LIBOR Rate Loans and same Business Day irrevocable notice with respect to Base
Rate Loans, in the form attached hereto as Exhibit D (a "Notice of Prepayment")
specifying the date and amount of repayment and whether the repayment is of
LIBOR Rate Loans, Base Rate Loans or a combination thereof, and, if of a
combination thereof, the amount allocable to each. Upon receipt of such notice,
the

                                       15
<PAGE>   22
Administrative Agent shall promptly notify each Lender. If any such notice
is given, the amount specified in such notice shall be due and payable on the
date set forth in such notice. Partial repayments shall be in a whole multiple
of $250,000 with respect to Base Rate Loans and $3,000,000 or a whole multiple
of $1,000,000 in excess thereof with respect to LIBOR Rate Loans. Each such
repayment with respect to any LIBOR Rate Loan shall be accompanied by any amount
required to be paid pursuant to Section 3.9 hereof. Any repayment of the Loans
will not affect the Borrowers' obligation to continue making payments as
required under any Hedging Agreement.

             (d) Limitation on Repayment of LIBOR Rate Loans. The Borrowers may
not repay any LIBOR Rate Loan on any day other than on the last day of the
Interest Period applicable thereto unless such repayment is accompanied by any
amount required to be paid pursuant to Section 3.9 hereof.

         Section 2.4. Notes.

           Each Lender's Loans and the obligation of the Borrowers to repay such
Loans shall be evidenced by a separate Note executed by the Borrowers payable to
the order of such Lender, representing the Borrowers' obligation to pay such
Lender's Commitment or, if less, the aggregate unpaid principal amount of all
Loans made and to be made by such Lender to the Borrowers hereunder, plus
interest and all other fees, charges and other amounts due thereon in accordance
with the terms of this Agreement or any other Loan Document. Each Note shall be
dated the date hereof and shall bear interest on the unpaid principal amount
thereof at the applicable interest rate per annum specified in Section 3.1.

         Section 2.5. Permanent Reduction of the Aggregate Commitment.

             (a) Voluntary Reduction. The Borrowers shall have the right at any
time and from time to time, upon at least five (5) Business Days prior written
notice to the Administrative Agent, to permanently reduce, without premium or
penalty, (i) the entire Aggregate Commitment at any time or (ii) portions of the
Aggregate Commitment, from time to time, in an aggregate principal amount not
less than $5,000,000 or any whole multiple of $1,000,000 in excess thereof.

             (b) Each permanent reduction permitted pursuant to this Section 2.5
shall be accompanied by a payment of principal sufficient to reduce the
aggregate outstanding Loans of the Lenders after such reduction to the Aggregate
Commitment as so reduced. Any reduction of the Aggregate Commitment to zero
shall be accompanied by payment of all outstanding Obligations and shall result
in the termination of the Commitments and the Working Capital Facility. If the
reduction of the Aggregate Commitment requires the repayment of any LIBOR Rate
Loan, such repayment shall be accompanied by any amount required to be paid
pursuant to Section 3.9 hereof.

Loan would otherwise expire on a day that is not a Business Day but is a day of
the month after which no further Business Day occurs in such month, such

for its account, the fees set forth in the separate fee letter agreement
executed by JLG and the Administrative Agent dated November 10, 1999.

         Section 3.4. Manner of Payment. Each payment by the Borrowers on
account of the principal of or interest on the Loans or of any fee, commission
or other amounts payable to the Lenders under this Agreement or any Note shall
be made not later than 1:00 p.m. (Philadelphia time) on the date specified for
payment under this Agreement to the Administrative Agent at the Administrative
Agent's Office for the account of the Lenders (other than as set forth below)
pro rata in accordance with their respective Commitment Percentages (except as
specified below), in Dollars, in immediately available funds and shall be made
without any set-off, counterclaim or deduction whatsoever. Any payment received
after such time but before 2:00 p.m. (Philadelphia time) on such day shall be
deemed a payment on such date for the purposes of Section 10.1, but for all
other purposes shall be deemed to have been made on the next succeeding Business
Day. Any payment received after 2:00 p.m. (Philadelphia time) shall be deemed to
have been made on the next succeeding Business Day for all purposes. Upon
receipt by the Administrative Agent of each such payment, the Administrative
Agent shall distribute to each Lender at its address for notices set forth
herein its pro rata share of such payment in accordance with such Lender's

                                       20
<PAGE>   27
Commitment Percentage (except as specified below) and shall wire advice of the
amount of such credit to each Lender. Each payment to the Administrative Agent
of the Lenders' facility fee shall be made in like manner. Each payment to the
Administrative Agent of Administrative Agent's fees or expenses shall be made
for the account of the Administrative Agent and any amount payable to any Lender
under Sections 3.8, 3.9, 3.10, 3.11 or 12.2 shall be paid to the Administrative
Agent for the account of the applicable Lender. Subject to Section 3.1(b)(ii) if
any payment under this Agreement or any Note shall be specified to be made upon
a day which is not a Business Day, it shall be made on the next succeeding day
which is a Business Day and such extension of time shall in such case be
included in computing any interest if payable along with such payment.

         Section 3.5. Credit of Payments and Proceeds. In the event that the
Borrowers shall fail to pay any of the Obligations when due and the Obligations
have been accelerated pursuant to Section 10.2, all payments received by the
Lenders upon the Notes and the other Obligations and all net proceeds from the
enforcement of the Obligations shall be applied first to all expenses then due
and payable by the Borrowers hereunder, then to all indemnity obligations then
due and payable by the Borrowers hereunder, then to all Administrative Agent's
fees then due and payable, then to all commitment and other fees and commissions
then due and payable, then to accrued and unpaid interest on the Notes and, if
applicable, any termination payments or other amounts due in respect of a
Hedging Agreement with any Lender (which such Hedging Agreement is permitted
hereunder) (pro rata in accordance with all such amounts due), then to the
principal amount of the Notes (pro rata in accordance with all such amounts due)
in that order.

         Section 3.6. Adjustments. If any Lender (a "Benefitted Lender") shall
at any time receive any payment of all or part of the Obligations owing to it,
or interest thereon, or if any Lender shall at any time receive any collateral
in respect to the Obligations owing to it (whether voluntarily or involuntarily,
by set-off or otherwise) in a greater proportion than any such payment to and
collateral received by any other Lender, if any, in respect of the Obligations
owing to such other Lender, or interest thereon, such Benefitted Lender shall
purchase for cash from the other Lenders such portion of each such other
Lender's Loans, or shall provide such other Lenders with the benefits of any
such collateral, or the proceeds thereof, as shall be necessary to cause such
Benefitted Lender to share the excess payment or benefits of such collateral or
proceeds ratably with each of the Lenders; provided, that if all or any portion
of such excess payment or benefits is thereafter recovered from such Benefitted
Lender, such purchase shall be rescinded, and the purchase price and benefits
returned to the extent of such recovery, but without interest. The Borrowers
agree that each Lender so purchasing a portion of another Lender's Loans may
exercise all rights of payment (including without limitation rights of set-off)
with respect to such portion as fully as if such Lender were the direct holder
of such portion.

         Section 3.7. Nature of Obligations of Lenders Regarding Loans;
Assumption by the Administrative Agent. The obligations of the Lenders under
this Agreement to make the Loans

                                       21
<PAGE>   28

are several and are not joint or joint and several. Unless the Administrative
Agent shall have received notice from a Lender prior to a proposed borrowing
date that such Lender will not make available to the Administrative Agent such
Lender's ratable portion of the amount to be borrowed on such date (which notice
shall not release such Lender of its obligations hereunder), the Administrative
Agent may assume that such Lender has made such portion available to the
Administrative Agent on the proposed borrowing date in accordance with Section
2.2(c), and the Administrative Agent may, in reliance upon such assumption, make
available to the Borrowers on such date a corresponding amount. If such amount
is made available to the Administrative Agent on a date after such borrowing
date, such Lender shall pay to the Administrative Agent on demand an amount,
until paid, equal to the product of (a) the amount not made available by such
Lender in accordance with the terms hereof, times (b) the daily average Federal
Funds Rate during such period as determined by the Administrative Agent, times
(c) a fraction, the numerator of which is the number of days that elapse from
and including such borrowing date to the date on which such amount not made
available by such Lender in accordance with the terms hereof shall have become
immediately available to the Administrative Agent and the denominator of which
is 360. A certificate of the Administrative Agent with respect to any amounts
owing under this Section shall be conclusive, absent manifest error. If such
Lender's Commitment Percentage of such borrowing is not made available to the
Administrative Agent by such Lender within three (3) Business Days of such
borrowing date, the Administrative Agent shall be entitled to recover such
amount made available by the Administrative Agent with interest thereon at the
rate per annum applicable to Base Rate Loans hereunder, on demand, from the
Borrowers. The failure of any Lender to make available its Commitment Percentage
of any Loan requested by the Borrowers shall not relieve it or any other Lender
of its obligation, if any, hereunder to make its Commitment Percentage of such
Loan available on the borrowing date, but no Lender shall be responsible for the
failure of any other Lender to make its Commitment Percentage of such Loan
available on the borrowing date.

         Section 3.8. Changed Circumstances.

             (a) Circumstances Affecting LIBOR Rate Availability. If with
respect to any Interest Period the Administrative Agent or any Lender (after
consultation with Administrative Agent) shall determine that, by reason of
circumstances affecting the foreign exchange and interbank markets generally,
deposits in eurodollars, in the applicable amounts are not being quoted via
Telerate Page 3750 or offered to the Administrative Agent or such Lender for
such Interest Period, then the Administrative Agent shall forthwith give notice
thereof to the Borrowers. Thereafter, until the Administrative Agent notifies
the Borrowers that such circumstances no longer exist, the obligation of the
Lenders to make LIBOR Rate Loans and the right of the Borrowers to convert any
Loan to or continue any Loan as a LIBOR Rate Loan shall be suspended, and the
Borrowers shall repay in full (or cause to be repaid in full) the then
outstanding principal amount of each such LIBOR Rate Loan together with accrued
interest thereon, on the last day of the then current Interest Period applicable
to such LIBOR Rate Loan or convert the then outstanding principal amount of each
such LIBOR Rate Loan to a Base Rate Loan as of the last day of such Interest
Period.

             (b) Laws Affecting LIBOR Rate Availability. If, after the date
hereof, the introduction of, or any change in, any Applicable Law or any change
in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any of their respective
Lending Offices) with any request or directive (whether or not having the force
of law) of any such Authority, central bank or comparable agency, shall make it
unlawful or impossible for any of the Lenders (or any of their respective
Lending Offices) to honor its obligations hereunder to make or maintain any
LIBOR Rate Loan, such Lender shall promptly give notice thereof to the
Administrative Agent and the Administrative Agent shall promptly give notice to
the Borrowers and the other Lenders. Thereafter, until the Administrative Agent
notifies the Borrowers that such circumstances no longer exist, (i) the
obligations of the Lenders to make LIBOR Rate Loans and the right of the
Borrowers to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be
suspended and thereafter the Borrowers may select only Base Rate Loans
hereunder, and (ii) if any of the Lenders may not lawfully continue to maintain
a LIBOR Rate Loan to the end of the then current Interest Period applicable
thereto as a LIBOR Rate Loan, the applicable LIBOR Rate Loan shall immediately
be converted to a Base Rate Loan for the remainder of such Interest Period.

             (c) Increased Costs. If, after the date hereof, the introduction
of, or any change in, any Applicable Law, or in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any of the Lenders (or any of their respective Lending Offices) with any
request or directive (whether or not having the force of law) of such Authority,
central bank or comparable agency:

                                       23
<PAGE>   30

                (i) shall subject any of the Lenders (or any of their respective
Lending Offices) to any tax, duty or other charge with respect to any Note or
shall change the basis of taxation of payments by Borrowers to any of the
Lenders (or any of their respective Lending Offices) of the principal of or
interest on any Note or any other amounts due under this Agreement in respect
thereof (except for changes in the rate of tax on the overall net income of any
of the Lenders or any of their respective Lending Offices imposed by the
jurisdiction in which such Lender is organized or is or should be qualified to
do business or such Lending Office is located); or

                (ii) shall impose, modify or deem applicable any reserve
(including without limitation any imposed by the Board of Governors of the
Federal Reserve System), special deposit, insurance or capital or similar
requirement against assets of, deposits with or for the account of, or credit
extended by any of the Lenders (or any of their respective Lending Offices) or
shall impose on any of the Lenders (or any of their respective Lending Offices)
or the foreign exchange and interbank markets any other condition affecting any
Note; and the result of any of the foregoing is to increase the costs to any of
the Lenders of maintaining any LIBOR Rate Loan or to reduce the yield or amount
of any sum received or receivable by any of the Lenders under this Agreement or
under the Notes in respect of a LIBOR Rate Loan, then such Lender shall promptly
notify the Administrative Agent, and the Administrative Agent shall promptly
notify the Borrowers of such fact and demand compensation therefor and, within
fifteen (15) days after such notice by the Administrative Agent, the Borrowers
shall pay to such Lender such additional amount or amounts as will compensate
such Lender or Lenders for such increased cost or reduction. The Administrative
Agent will promptly notify the Borrowers of any event of which it has knowledge
which will entitle such Lender to compensation pursuant to this Section 3.8(c);
provided, that the Administrative Agent shall incur no liability whatsoever to
the Lenders or the Borrowers in the event it fails to do so. The amount of such
compensation shall be determined, in the applicable Lender's sole reasonable
discretion, based upon the assumption that such Lender funded its Commitment
Percentage of the LIBOR Rate Loans in the London interbank market and using any
reasonable attribution or averaging methods which such Lender deems appropriate
and practical. A certificate of such Lender setting forth the basis for
determining such amount or amounts necessary to compensate such Lender shall be
forwarded to the Borrowers through the Administrative Agent and shall be
conclusively presumed to be correct save for manifest error.

         Section 3.9. Indemnity. The Borrowers hereby indemnify each of the
Lenders against any loss or expense which may arise or be attributable to such
Lender's obtaining, liquidating or employing deposits or other funds acquired to
effect, fund or maintain any LIBOR Rate Loan (a) as a consequence of any failure
by the Borrowers to make any payment when due of any amount due hereunder in
connection with a LIBOR Rate Loan, (b) due to any failure of the Borrowers to
borrow on a date specified therefor in a Notice of Borrowing or Notice of
Continuation/Conversion or (c) due to any payment, prepayment or conversion of
any LIBOR Rate Loan on a

                                       24
<PAGE>   31
date other than the last day of the Interest Period therefor. The amount of such
loss or expense shall be determined, in the applicable Lender's sole reasonable
discretion, based upon the assumption that such Lender funded its Commitment
Percentage of the LIBOR Rate Loans in the London interbank market and using any
reasonable attribution or averaging methods which such Lender deems appropriate
and practical. A certificate of such Lender setting forth the basis for
determining such amount or amounts necessary to compensate such Lender shall be
forwarded to the Borrowers through the Administrative Agent and shall be
conclusively presumed to be correct save for manifest error.

         Section 3.10. Capital Requirements. If either (a) the introduction of,
or any change in, or in the interpretation of, any Applicable Law or (b)
compliance with any guideline or request from any central bank or comparable
agency or other Governmental Authority (whether or not having the force of law),
has or would have the effect of reducing the rate of return on the capital of,
or has affected or would affect the amount of capital required to be maintained
by, any Lender or any corporation controlling such Lender as a consequence of,
or with reference to the Commitments and other commitments of this type, below
the rate which the Lender or such other corporation could have achieved but for
such introduction, change or compliance, and the costs of such change in capital
requirements are not reflected in the LIBOR Rate (other than the Eurodollar
Reserve Percentage to the extent reflected in the LIBOR Rate) then within five
(5) Business Days after written demand by any such Lender, the Borrowers shall
pay to such Lender from time to time as specified by such Lender additional
amounts sufficient to compensate such Lender or other corporation for such
reduction. A certificate as to such amounts submitted to the Borrowers and the
Administrative Agent by such Lender, shall, in the absence of manifest error, be
presumed to be correct and binding for all purposes. Each Lender and the
Administrative Agent shall allocate such cost increases among its customers in
good faith and on an equitable basis.

         Section 3.11. Taxes.

             (a) Payments Free and Clear. Subject to compliance by Lenders with
Section 3.11(e), any and all payments by the Borrowers hereunder or under the
Notes shall be made free and clear of and without deduction for any and all
present or future taxes, levies, imposts, deductions, charges or withholding,
and all liabilities with respect thereto excluding, (i) in the case of each
Lender and the Administrative Agent, income and franchise taxes imposed by the
jurisdiction under the laws of which such Lender or the Administrative Agent (as
the case may be) is organized or is or should be qualified to do business or any
political subdivision thereof and (ii) in the case of each Lender, income and
franchise taxes imposed by the jurisdiction of such Lender's Lending Office or
any political subdivision thereof (all such non-excluded taxes, levies, imposts,
deductions, charges, withholdings and liabilities being hereinafter referred to
as "Taxes"). If the Borrowers shall be required by law to deduct any Taxes from
or in respect of any sum payable hereunder or under any Note to any Lender or
the Administrative Agent, (A) the sum payable shall be increased as may be
necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 3.11) such Lender or
the Administrative Agent (as the case may be) receives an amount equal to the
amount such party would have received had no such deductions been made, (B) the
Borrowers shall make such deductions, (C) the Borrowers shall pay the full
amount deducted to the relevant taxing authority or other authority in
accordance with applicable law, and (D) the Borrowers shall deliver to the
Administrative Agent evidence of such payment to the relevant taxing authority
or other authority in the manner provided in Section 3.11(d).

             (b) Stamp and Other Taxes. In addition, the Borrowers shall pay any
present or future stamp, registration, recordation or documentary taxes or any
other similar fees or charges or excise or property taxes, levies of the United
States or any state or political subdivision thereof or any applicable foreign
jurisdiction which arise from any payment made hereunder or from the execution,
delivery or registration of, or otherwise with respect to, this Agreement, the
Loans, the other Loan Documents or the perfection of any rights or security
interest in respect thereto (hereinafter referred to as "Other Taxes").

             (c) Indemnity. The Borrowers shall indemnify each Lender and the
Administrative Agent for the full amount of Taxes and Other Taxes (including,
without limitation, any Taxes and Other Taxes imposed by any jurisdiction on
amounts payable under this Section 3.11) paid by such Lender or the
Administrative Agent (as the case may be) and any additional liability or
obligation (including penalties, interest and expenses) arising therefrom or
with respect thereto paid by such Lender or the Administrative Agent. Such
indemnification shall be made within thirty (30) days from the date such Lender
or the Administrative Agent (as the case may be) makes written demand therefor.

                                       26
<PAGE>   33

             (d) Evidence of Payment. Within thirty (30) days after the date of
any payment of Taxes or Other Taxes, the Borrowers shall furnish to the
Administrative Agent, at its address referred to in Section 12.1, the original
or a certified copy of a receipt evidencing payment thereof or other evidence of
payment satisfactory to the Administrative Agent.

             (e) Delivery of Tax Forms. Each Lender organized under the laws of
a jurisdiction other than the United States or any state thereof shall deliver
to the Borrowers, with a copy to the Administrative Agent, on the Closing Date
or concurrently with the delivery of the relevant Assignment and Acceptance, as
applicable, (i) two United States Internal Revenue Service Forms 4224 or Forms
1001, as applicable (or successor forms) properly completed and certifying in
each case that such Lender is entitled to a complete exemption from withholding
or deduction for or on account of any United States federal income taxes, and
(ii) an Internal Revenue Service Form W-8 or W-9 or successor applicable form,
as the case may be, to establish an exemption from United States backup
withholding taxes. Each such Lender further agrees to deliver to the Borrowers,
with a copy to the Administrative Agent, a Form 1001 or 4224 and Form W-8 or
W-9, or successor applicable forms or manner of certification, as the case may
be, on or before the date that any such form expires or becomes obsolete or
after the occurrence of any event requiring a change in the most recent form
previously delivered by it to the Borrowers, certifying in the case of a Form
1001 or 4224 that such Lender is entitled to receive payments under this
Agreement without deduction or withholding of any United States federal income
taxes (unless in any such case an event (including without limitation any change
in treaty, law or regulation) has occurred prior to the date on which any such
delivery would otherwise be required which renders such forms inapplicable or
the exemption to which such forms relate unavailable and such Lender notifies
the Borrowers and the Administrative Agent that it is not entitled to receive
payments without deduction or withholding of United States federal income taxes)
and, in the case of a Form W-8 or W-9, establishing an exemption from United
States backup withholding tax.

             (f) Survival. Without prejudice to the survival of any other
agreement of the Borrower hereunder, the agreements and obligations of the
Borrowers contained in this Section 3.11 shall survive the payment in full of
the Obligations and the termination of the Commitments.

             (a) Continuation of Representations and Warranties. The
representations and warranties contained in Article V shall be true and correct
in all material respects on and as of such borrowing or issuance date with the
same effect as if made on and as of such date, except for any representation and

remain true and correct as of such earlier date.

             (b) No Existing Default. No Default or Event of Default shall have

                                    ARTICLE V
                 REPRESENTATIONS AND WARRANTIES OF THE BORROWERS

         Section 5.1. Representations and Warranties. To induce the
Administrative Agent and Lenders to enter into this Agreement and to induce the
Lenders to make Loans, each Borrower hereby represents and warrants to the
Administrative Agent and Lenders both before and after giving effect to the
transactions contemplated hereunder that:

             (a) Organization; Power; Qualification. Each Borrower and each
Subsidiary is duly organized, validly existing and in good standing under the
laws of the jurisdiction of its incorporation or formation, has the power and
authority to own its properties

                                       31
<PAGE>   38
and to carry on its business as now being and hereafter proposed to be conducted
and is duly qualified and authorized to do business in each jurisdiction in
which the character of its properties or the nature of its business requires
such qualification and authorization, except where any failure to be so
qualified would not have a Material Adverse Effect. The jurisdictions in which
the Borrowers and their Subsidiaries are organized and qualified to do business
as of the Closing Date are described on Schedule 5.1(a).

             (b) Ownership; Investments. Each Subsidiary of any Borrower as of
the Closing Date is listed on Schedule 5.1(b). As of the Closing Date, except as
set forth on Schedule 5.1(b), all outstanding shares and membership interests of
the Subsidiaries are held by JLG. All outstanding shares of the Borrowers and
their Subsidiaries have been duly authorized and validly issued and are fully
paid and nonassessable. As of the Closing Date, there are no outstanding stock
purchase warrants, subscriptions, options, securities, instruments or other
rights of any type or nature whatsoever, which are convertible into,
exchangeable for or otherwise provide for or permit the issuance of capital
stock of any Borrower or any Subsidiary, except as described on Schedule 5.1(b).
No Borrower has any Subsidiaries or Affiliates, or investments in or loans to
any Person other than those Persons listed on Schedule 5.1(b) or loans or
investments permitted by Section 9.4.

             (c) Authorization of Agreement, Loan Documents and Borrowing. Each
Borrower and each Subsidiary, to the extent a party thereto, has the right,
power and authority under the laws of the jurisdiction of its formation and
under its articles or certificate of incorporation and bylaws, or its articles
of organization and operating agreement, and has taken all necessary corporate
and other action to authorize the execution, delivery and performance of this
Agreement and each of the other Loan Documents to which it is a party in
accordance with their respective terms. This Agreement and each of the other
Loan Documents have been duly executed and delivered by the duly authorized
officers of each Borrower and each Subsidiary party thereto, and each such
document constitutes the legal, valid and binding obligation of each Borrower
party thereto, enforceable in accordance with its terms, except as such
enforcement may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar state or federal debtor relief laws from time to time in effect which
affect the enforcement of creditors' rights in general and the availability of
equitable remedies.

             (d) Compliance of Agreement, Loan Documents and Borrowing with
Laws, Etc. The execution, delivery and performance by each Borrower and each
Subsidiary of the Loan Documents to which each such Person is a party, in
accordance with their respective terms, the borrowings hereunder and the
transactions contemplated hereby do not and will not, by the passage of time,
the giving of notice or otherwise, (i) require any Governmental Approval or
violate any Applicable Law relating to any Borrower or any Subsidiary, (ii)
conflict with, result in a breach of or constitute a default under the articles
of incorporation, bylaws or other organizational documents of any Borrower or
any Subsidiary or any material indenture, agreement or other instrument to which
such Person is a party or by which any of its properties

                                       32
<PAGE>   39
may be bound or any Governmental Approval relating to such Person, or (iii)
result in or require the creation or imposition of any Lien upon or with respect
to any property now owned or hereafter acquired by such Person other than Liens
arising under the Loan Documents.

             (e) Compliance with Law; Governmental Approvals. Each Borrower and
each Subsidiary (i) has all Governmental Approvals required by any Applicable
Law for it to conduct its business, each of which is in full force and effect,
is final and not subject to review on appeal and is not the subject of any
pending or, to the best of its knowledge, threatened attack by direct or
collateral proceeding, and (ii) is in compliance with each Governmental Approval
applicable to it and in compliance with all other Applicable Laws relating to it
or any of its respective properties, except where failure to comply would not
have a Material Adverse Effect.

             (f) Tax Returns and Payments. Each Borrower and each Subsidiary has
duly filed or caused to be filed all federal, state, local and other tax returns
required by Applicable Law to be filed, and has paid, or made adequate provision
for the payment of, all federal, state, local and other taxes, assessments and
governmental charges or levies upon it and its property, income, profits and
assets which are due and payable, except such taxes as are being contested in
good faith and as to which adequate reserves have been provided. To the
knowledge of the Responsible Officers, no Governmental Authority has asserted
any Lien or other claim against any Borrower or any Subsidiary with respect to
unpaid taxes which has not been discharged or resolved. The charges, accruals
and reserves on the books of each Borrower and each Subsidiary in respect of
federal, state, local and other taxes for all Fiscal Years and portions thereof
since the organization of the Borrowers and the Subsidiaries are in the judgment
of the Borrowers adequate, and the Borrowers have no knowledge of any additional
taxes or assessments for any of such years.

             (g) Intellectual Property Matters. Each Borrower and each
Subsidiary owns or possesses rights to use all franchises, licenses, copyrights,
copyright applications, patents, patent rights or licenses, patent applications,
trademarks, trademark rights, trade names, trade name rights, and all other
intellectual property which is material to its business. No event has occurred
which permits, or after notice or lapse of time or both would permit, the
revocation or termination of any such rights, and no Borrower nor any Subsidiary
thereof is liable to any Person for infringement under Applicable Law with
respect to any such rights as a result of its business operations, except where
such revocation, termination of infringement would not have a Material Adverse
Effect.

                                       33
<PAGE>   40

             (h) Environmental Matters. Except with respect to any noncompliance
with the following that would not have a Material Adverse Effect,

                 (i) The properties owned, leased or operated by each Borrower
and each Subsidiary now or in the past do not contain, and to their knowledge
have not previously contained, any Hazardous Materials in amounts or
concentrations which (A) constitute or constituted a violation of applicable
Environmental Laws or (B) could give rise to liability under applicable
Environmental Laws;

                 (ii) Each Borrower, each Subsidiary and their properties and
all operations conducted in connection therewith are in compliance, and have
been in compliance, with all applicable Environmental Laws, and there is no
contamination at, under or about such properties or such operations which could
interfere with the continued operation of such properties or impair the fair
saleable value thereof; and each Borrower and each Subsidiary has received all
permits and filed all notifications to carry on its respective business(es);

                 (iii) No Borrower or Subsidiary has received any notice of
violation, alleged violation, non-compliance, liability or potential liability
regarding environmental matters, Hazardous Materials, or compliance with
Environmental Laws, nor does any Borrower or Subsidiary have knowledge or reason
to believe that any such notice will be received or is being threatened;

                 (iv) Hazardous Materials have not been transported or disposed
of to or from the properties owned, leased or operated by the Borrowers and
their Subsidiaries in violation of, or in a manner or to a location which could
give rise to liability under, Environmental Laws, nor have any Hazardous
Materials been generated, treated, stored or disposed of at, on or under any of
such properties in violation of, or in a manner that could give rise to
liability under, any applicable Environmental Laws;

                 (v) No judicial proceedings or governmental or administrative
action is pending, or, to the knowledge of any Borrower, threatened, under any
Environmental Law to which any Borrower or any Subsidiary is or will be named as
a party, nor are there any consent decrees or other decrees, consent orders,
administrative orders or other orders, or other administrative or judicial
requirements outstanding under any Environmental Law with respect to any
Borrower, any Subsidiary or such properties or operations; and

                 (vi) There has been no release, or to the best of each
Borrower's knowledge, threat of release, of Hazardous Materials at or from
properties owned, leased or operated by any Borrower or any Subsidiary, now or
in the past, in violation of or in amounts or in a manner that could give rise
to liability under Environmental Laws.

             (i) ERISA.

                 (i) As of the Closing Date, no Borrower, Subsidiary or ERISA
Affiliate maintains or contributes to, or has any obligation under, any Employee
Benefit Plans other than those identified on Schedule 5.1(i);

                 (ii) Each Borrower and each ERISA Affiliate is in material
compliance with all applicable provisions of ERISA and the regulations and
published interpretations thereunder with respect to all Employee Benefit Plans
except for any required amendments for which the remedial amendment period as
defined in Section 401(b) of the Code has not yet expired. Each Employee Benefit
Plan that is intended to be qualified under Section 401(a) of the Code has been
determined by the Internal Revenue Service to be so qualified, and each trust
related to such plan has been determined to be exempt under Section 501(a) of
the Code. No material liability has been incurred by any Borrower or any ERISA
Affiliate which remains unsatisfied for any taxes or penalties with respect to
any Employee Benefit Plan or any Multiemployer Plan. Except as set forth on
Schedule 5.1(i)(ii), no Borrower, Subsidiary or ERISA Affiliate maintains or
contributes to or has maintained or contributed to any Multiemployer Plan under
which such Borrower, Subsidiary or ERISA Affiliate could have any withdrawal
liability.

                 (iii) No Pension Plan that does not satisfy the requirements
for a standard termination under Section 4041(b) of ERISA has been terminated,
nor has any accumulated funding deficiency (as defined in Section 412 of the
Code) been incurred (without regard to any waiver granted under Section 412 of
the Code), nor has any funding waiver from the Internal Revenue Service been
received or requested with respect to any Pension Plan, nor has any Borrower or
any ERISA Affiliate failed to make any material contributions or to pay any
material amounts due and owing as required by Section 412 of the Code, Section
302 of ERISA or the terms of any Pension Plan prior to the due dates of such
contributions under Section 412 of the Code or Section 302 of ERISA, nor has
there been any event requiring any disclosure under Section 4041(c)(3)(C) or
4063(a) of ERISA with respect to any Pension Plan;

                 (iv) No Borrower or ERISA Affiliate has: (A) engaged in a
nonexempt prohibited transaction described in Section 406 of the ERISA or
Section 4975 of the Code, (B) incurred any liability to the PBGC which remains
outstanding other than the payment of premiums and there are no premium payments
for which the deadline for payment has passed and which are due and unpaid, (C)
failed to make a required material contribution or material payment to a
Multiemployer Plan, or (D) failed to make a required material installment or
other required material payment under Section 412 of the Code;

                 (v) No Termination Event has occurred or is reasonably expected
to occur; and

                                       35
<PAGE>   42

                 (vi) No proceeding, claim, lawsuit and/or investigation is
existing or, to the knowledge of the Responsible Officers, threatened concerning
or involving any Employee Benefit Plan, other than routine claims for benefits.

                 (vii) Except as set forth on Schedule 5.1(i)(vii), the
aggregate liability for accrued benefits and other ancillary benefits under each
Pension Plan that is or will be sponsored or maintained by any Borrower, any
Subsidiary or any ERISA Affiliate (determined on the basis of the actuarial
assumptions prescribed for valuing benefits under Financial Accounting Standard
132 does not exceed the aggregate fair market value of the assets under each
Pension Plan.

                 (viii) The aggregate liability, if any, of each Borrower,
Subsidiary and ERISA Affiliate arising out of or relating to a failure of any
Employee Benefit Plan to comply with the provisions of ERISA or the Code, will
not have a Material Adverse Effect on any Borrower or Subsidiary; and

                 (ix) Except as set forth on Schedule 5.1(i)(ix), there does not
exist any unfunded liability (determined on the basis of actuarial assumptions
utilized by the actuary for the plan in preparing the most recent Annual Report)
of any Borrower, Subsidiary or ERISA Affiliate under any plan, program or
arrangement providing post-retirement life or health benefits.

             (j) Margin Stock. No Borrower or Subsidiary is engaged principally
or as one of its activities in the business of extending credit for the purpose
of purchasing or carrying any margin stock (as each such term is defined or used
in Regulation U of the Board of Governors of the Federal Reserve System). No
part of the proceeds of any of the Loans will be used for any purpose which
violates the provisions of Regulation T, U or X of such Board of Governors.

             (k) Government Regulation. No Borrower or Subsidiary is an
"investment company" or a company "controlled" by an "investment company" (as
each such term is defined or used in the Investment Company Act of 1940, as
amended). No Borrower or Subsidiary is, or after giving effect to any Extension
of Credit will be, subject to regulation under the Public Utility Holding
Company Act of 1935, as amended, or any other Applicable Law which limits its
ability to incur or consummate the transactions contemplated hereby.

             (l) Material Contracts. Schedule 5.1(l) sets forth a complete and
accurate list of all Material Contracts of each Borrower and each Subsidiary in
effect as of the Closing Date not listed on any other Schedule hereto; other
than as set forth in Schedule 5.1(l), each such Material Contract is, and after
giving effect to the consummation of the transactions contemplated by the Loan
Documents will be, in full force and effect in accordance with the terms
thereof. Each Borrower and each Subsidiary has delivered to the Administrative
Agent a

                                       36
<PAGE>   43
true and complete copy of each Material Contract required to be listed on
Schedule 5.1(l) or any other Schedule hereto.

             (m) Employee Relations. No Borrower or Subsidiary is, as of the
Closing Date, party to any collective bargaining agreement nor has any labor
union been recognized as the representative of its employees, except as set
forth on Schedule 5.1(m). Except as set forth in Schedule 5.1(m), no Borrower
knows of any pending, threatened or contemplated strikes, work stoppage or other
collective labor disputes involving its employees or those of its Subsidiaries.

             (n) Burdensome Provisions. No Borrower or Subsidiary is a party to
any indenture, agreement, lease or other instrument, or subject to any corporate
or partnership restriction, Governmental Approval or Applicable Law which is so
unusual or burdensome as in the foreseeable future could, in the good faith
judgment of the Responsible Officers, be reasonably expected to have a Material
Adverse Effect. No Borrower or Subsidiary presently anticipates that future
expenditures needed to meet the provisions of any existing statutes, orders,
rules or regulations of a Governmental Authority will be so burdensome as to
have a Material Adverse Effect.

             (o) Financial Statements. Copies of the Consolidated balance sheet
of JLG and its Subsidiaries as of July 31, 1999 and the related statements of
income and retained earnings and cash flows for the Fiscal Years then ended (the
"Audited JLG Financial Statements") have been furnished to the Administrative
Agent and each Lender. The Audited JLG Financial Statements, including the
related schedules and notes thereto, (Y) have been prepared in accordance with
GAAP and (Z) are complete and correct and fairly present the assets, liabilities
and financial position of JLG and its Subsidiaries as at such dates and the
results of operations and changes of financial position for the periods then
ended. Neither JLG nor any of its Subsidiaries has any Debt, obligation or other
unusual forward or long-term commitment which is not, in accordance with GAAP,
fairly presented in the foregoing financial statements or in the notes thereto.

             (p) No Material Adverse Change. (i) Since July 31, 1999, there has
been no material adverse change in the properties, business, operations,
prospects, or condition (financial or otherwise) of JLG or its Subsidiaries, on
a Consolidated basis, that could reasonably be expected to have a Material
Adverse Effect.

             (q) Solvency. Excluding intercompany indebtedness, each Borrower
and, to the best of each Borrower's knowledge, each Subsidiary is, and after
receipt and application of the first advance under this Agreement will be,
solvent such that (i) the fair value of its assets (including without limitation
the fair salable value of the goodwill and other intangible property of such
Borrower or Subsidiary) is greater than the total amount of its liabilities,
including without limitation contingent liabilities, (ii) the present fair
salable value of

                                       37
<PAGE>   44
its assets (including without limitation the fair salable value of the goodwill
and other intangible property of such Borrower or Subsidiary) is not less than
the amount that will be required to pay the probable liability on their debts as
they become absolute and matured, and (iii) they are able to realize upon their
assets and pay their debts and other liabilities, contingent obligations and
other commitments as they mature in the normal course of business. No Borrower
or Subsidiary intends to, nor believes that it will, incur debts or liabilities
beyond its ability to pay as such debts and liabilities mature, and no Borrower
or Subsidiary is engaged in a business or transaction, or about to engage in a
business or transaction, for which its property would constitute unreasonably
small capital after giving due consideration to the prevailing practice and
industry in which it is engaged. For purposes of this Section, in computing the
amount of contingent liabilities at any time, it is intended that such
liabilities will be computed at the amount which, in light of all the facts and
circumstances existing at such time, represents the amount that reasonably can
be expected to become an actual matured liability of the applicable Borrower or
Subsidiary.

         Each Borrower hereby agrees that to the extent a Borrower shall have
paid more than its proportionate share of any payment made hereunder, such
Borrower shall be entitled to seek and receive contribution from and against any
other Borrower which has not paid its proportionate share of such payment;
provided however such Borrower shall not seek any such contribution from any
other Borrower until the Obligations have been paid in full and the Commitments
of the Lenders hereunder have been terminated. The provisions of this Section
shall in no respect limit the obligations and liabilities of any Borrower to
Lenders, and each Borrower shall remain liable to Lenders, jointly and
severally, for the full amount of Borrowers' obligations hereunder and under the
other Loan Documents.

             (r) Titles to Properties. Each Borrower and each Subsidiary has
such title to the real property, personal property and assets owned by it as is
necessary to the conduct of its business including, but not limited to, those
reflected on the balance sheets of JLG and its Subsidiaries delivered pursuant
to Section 5.1(o), except those which have been disposed of by the Borrowers or
their Subsidiaries subsequent to such date which dispositions have been in the
ordinary course of business or as otherwise expressly permitted hereunder.

             (s) Liens. None of the properties and assets of any Borrower or any
Subsidiary thereof is subject to any Lien, except Liens permitted pursuant to
Section 9.3. No financing statement under the Uniform Commercial Code of any
state which names any Borrower or any Subsidiary thereof or any of their
respective trade names or divisions as debtor and which has not been terminated,
has been filed in any state or other jurisdiction and no Borrower or any
Subsidiary thereof has signed any such financing statement or any security
agreement authorizing any secured party thereunder to file any such financing
statement, except, in each case, to perfect those Liens permitted by Section 9.3
hereof.

                                       38
<PAGE>   45

             (t) Debt and Guaranty Obligations. Except for such Debt and
Guaranty Obligations otherwise permitted pursuant to this Agreement, Schedule
5.1(t) is a complete and correct listing of all Debt and Guaranty Obligations of
each Borrower and each Subsidiary as of the Closing Date in excess of
$1,000,000. Each Borrower and each Subsidiary has performed and is in compliance
with all of the terms of such Debt and Guaranty Obligations and all instruments
and agreements relating thereto, and no default or event of default, or event or
condition which with notice or lapse of time or both would constitute such a
default or event of default on the part of any Borrower or any Subsidiary exists
with respect to any such Debt or Guaranty Obligation.

             (u) Litigation. Except for matters existing on the Closing Date and
set forth on Schedule 5.1(u), or other matters which are not reasonably likely
to have a Material Adverse Effect, there are no actions, suits or proceedings
pending nor, to the knowledge of any Borrower, threatened against or in any
other way relating adversely to or affecting any Borrower or any Subsidiary
thereof or any of their respective properties in any court or before any
arbitrator of any kind or before or by any Governmental Authority.

             (v) Absence of Defaults. No event has occurred or is continuing
which constitutes a Default or an Event of Default, or which constitutes, or
which with the passage of time or giving of notice or both would constitute, a
default or event of default by any Borrower or any Subsidiary under any Material
Contract or judgment, decree or order to which any Borrower or any Subsidiary is
a party or by which any Borrower or any Subsidiary or any of their respective
properties may be bound or which would require any Borrower or any Subsidiary to
make any payment thereunder prior to the scheduled maturity date therefor.

             (w) Accuracy and Completeness of Information. All written
information, reports and other papers and data produced by or on behalf of each
Borrower and any Subsidiary thereof and furnished to the Lenders, taken as a
whole, including without limitation all financial statements, were, at the time
the same were so furnished, complete and correct in all material respects and
did not contain any untrue statement of a material fact or omit to state a
material fact necessary to make the statement contained therein not materially
misleading. No document, including without limitation any financial statement,
furnished or written statement made to the Administrative Agent or the Lenders
by any Borrower or any Subsidiary thereof in connection with the negotiation,
preparation or execution of this Agreement or any of the Loan Documents contains
or will contain any untrue statement of a fact material to the creditworthiness
of any Borrower or any Subsidiary nor omits nor will omit to state a fact
necessary in order to make the statements contained therein not materially
misleading. As of the Closing Date, no Borrower is aware of any facts which it
has not disclosed in writing, including without limitation in public filings
under the 1934 Act, to the Administrative Agent having a Material Adverse Effect
as of the Closing Date, or insofar as such Borrower can now foresee, could
reasonably be expected to have a Material Adverse Effect.

                                       39
<PAGE>   46

             (x) Year 2000 Compliance. Borrowers and Subsidiaries have commenced
to conduct a review and assessment of their material computer systems and
applications, micro-processor based goods and equipment owned or used by them in
their business, and all products currently sold by them, and are making inquiry
of their material suppliers, vendors and customers, with respect to
functionality before, during and after the year 2000 (the "Year 2000 Problem").
Borrowers have prepared a program to ensure that all such systems, goods,
equipment and products owned or used by them and material to the conduct of
their business will be Year 2000 Compliant in a timely manner. Borrowers
reasonably believe, based on the foregoing review, assessment and inquiry that
the Year 2000 Problem will not result in a Material Adverse Effect.

             (y) Fees and Commissions. No Borrower owes any fees or commissions
of any kind, and no Borrower knows of any claim for any fees or commissions, in
connection with Borrowers' obtaining the Commitment or the Loans from Lenders,
except those provided herein.

             (z) Foreign Assets Control Regulations. Neither the borrowing by
Borrowers nor their use of the proceeds thereof will violate the Foreign Assets
Control Regulations, the Foreign Funds Control Regulations, the Transactions
Control Regulations, the Cuban Assets Control Regulations, the Iranian Assets
Control Regulations, the Libyan Sanctions Regulations, the Nicaraguan Trade
Control Regulations or the South African Transactions Regulations of the United
States Treasury Department (31 C.F.R. Subtitle B, Chapter V, as amended).

             (aa) Public Utility Holding Company Act. No Borrower is a "public
utility holding company" within the meaning of the Public Utility Holding
Company Act of 1935, as amended (the "1935 Act"), nor does the execution,
delivery and performance of this Agreement and the Notes require any filing,
authorization or consent under the 1935 Act.

         Section 5.2. Survival of Representations and Warranties, Etc. All
representations and warranties set forth in this Article V and all
representations and warranties contained in any certificate or any of the Loan
Documents (including but not limited to any such representation or warranty made
in or in connection with any amendment thereto) shall constitute representations
and warranties made under this Agreement. All representations and warranties
made under this Agreement shall be made or deemed to be made at and as of the
Closing Date, shall survive the Closing Date and shall not be waived by the
execution and delivery of this Agreement, any investigation made by or on behalf
of the Lenders or any borrowing hereunder.

                                   ARTICLE VI
                        FINANCIAL INFORMATION AND NOTICES

         Until all the Obligations have been paid and satisfied in full and the
Commitments terminated, unless consent has been obtained in the manner set forth
in Section 12.13 hereof, the Borrowers will furnish or cause to be furnished to
the Administrative Agent and to the Lenders at their respective addresses as set
forth on Schedule 2, or such other office as may be designated by the
Administrative Agent and Lenders from time to time:

         Section 6.1. Financial Statements.

             (a) Quarterly Financial Statements. As soon as practicable and in
any event within forty-five (45) days after the end of the first three (3)
fiscal quarters of each Fiscal Year, an unaudited Consolidated balance sheet of
JLG and its Consolidated Subsidiaries as of the close of such fiscal quarter and
unaudited Consolidated statements of income, retained earnings and cash flows
for the fiscal quarter then ended and that portion of the Fiscal Year then
ended, including the notes thereto, all in reasonable detail setting forth in
comparative form the corresponding figures for the preceding Fiscal Year and
prepared by the Borrowers in accordance with GAAP (excluding normal year-end
adjustments and other exceptions permitted under Regulation S-X promulgated by
the Securities Exchange Commission) and, if applicable, containing disclosure of
the effect on the financial position or results of operations of any change in

Agreement and such other Loan Documents, together with such other powers as are

elsewhere in this Agreement or such other Loan Documents, the Administrative
Agent shall not have any duties or responsibilities, except those expressly set
forth herein and therein, or any fiduciary relationship with any Lender, and no
implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or the other Loan Documents or
otherwise exist against the Administrative Agent. Any reference to the

execute any of its respective duties under this Agreement and the other Loan
Documents by or through agents or attorneys-in-fact and shall be entitled to

of any agents or attorneys-in-fact (other than the Administrative Agent's

responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by the Borrowers or any of their Subsidiaries
or any officer thereof contained in this Agreement or the other Loan Documents
or in any certificate, report, statement or other document referred to or
provided for in, or received by the Administrative Agent under or in connection
with, this Agreement or the other Loan Documents or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement or
the other Loan Documents or for any failure of the Borrowers or any of their
Subsidiaries to perform its obligations hereunder or thereunder. The
Administrative Agent shall not be under any obligation to any Lender to
ascertain or to

                                       59
<PAGE>   66
inquire as to the observance or performance of any of the agreements contained

records of the Borrowers or any of their Subsidiaries.

         Section 11.4. Reliance by the Administrative Agent. The Administrative

any note, writing, resolution, notice, consent, certificate, affidavit, letter,
cablegram, telegram, telecopy, telex or teletype message, statement, order or
other document or conversation believed by it to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including without limitation counsel to the
Borrowers), independent accountants and other experts selected by the
Administrative Agent. The Administrative Agent may deem and treat the payee of
any Note as the owner thereof for all purposes unless such Note shall have been
transferred in accordance with Section 12.10 hereof. The Administrative Agent
shall be fully justified in failing or refusing to take any action under this
Agreement and the other Loan Documents unless it shall first receive such advice
or concurrence of the Required Lenders (or, when expressly required hereby or by
the relevant other Loan Document, all the Lenders) as it deems appropriate or it
shall first be indemnified to its satisfaction by the Lenders against any and
all liability and expense which may be incurred by it by reason of taking or
continuing to take any such action except for its own gross negligence or
willful misconduct. The Administrative Agent shall in all cases be fully
protected in acting, or in refraining from acting, under this Agreement and the
Notes in accordance with a request of the Required Lenders (or, when expressly
required hereby, all the Lenders), and such request and any action taken or
failure to act pursuant thereto shall be binding upon all the Lenders and all
future holders of the Notes.

         Section 11.5. Notice of Default. The Administrative Agent shall not be
deemed to have knowledge or notice of the occurrence of any Default or Event of
Default hereunder unless it has received notice from a Lender or the Borrowers
referring to this Agreement, describing such Default or Event of Default and
stating that such notice is a "notice of default." In the event that the
Administrative Agent receives such a notice, it shall promptly give notice
thereof to the Lenders. The Administrative Agent shall take such action with
respect to such Default or Event of Default as shall be reasonably directed by
the Required Lenders; provided that unless and until the Administrative Agent
shall have received such directions, the Administrative Agent may (but shall not
be obligated to) take such action, or refrain from taking such action, with
respect to such Default or Event of Default as it shall deem advisable in the
best interests of the Lenders, except to the extent that other provisions of
this Agreement expressly require that any such action be taken or not be taken
only with the consent and authorization or the request of the Lenders or
Required Lenders, as applicable.

         Section 11.6. Non-Reliance on the Administrative Agent and Other
Lenders. Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact, Subsidiaries or Affiliates has made any

                                       60
<PAGE>   67
representations or warranties to it and that no act by the Administrative Agent
hereinafter taken, including any review of the affairs of the Borrowers or any
of their Subsidiaries, shall be deemed to constitute any representation or
warranty by the Administrative Agent to any Lender. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
the Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own appraisal of and
investigation into the business, operations, property, financial and other
condition and creditworthiness of the Borrowers and their Subsidiaries and made
its own decision to make its Loans and enter into this Agreement. Each Lender
also represents that it will, independently and without reliance upon the
Administrative Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrowers and their
Subsidiaries. Except for notices, reports and other documents expressly required
to be furnished to the Lenders by the Administrative Agent hereunder or by the
other Loan Documents, the Administrative Agent shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, operations, property, financial and other condition or
creditworthiness of the Borrowers or any of their Subsidiaries which may come
into the possession of the Administrative Agent or any of its respective
officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or
Affiliates.

         Section 11.7. Indemnification. The Lenders agree to indemnify the
Administrative Agent in its capacity as such and (to the extent not reimbursed
by the Borrowers and without limiting the obligation of the Borrowers to do so),
ratably according to the respective amounts of their Commitment Percentages,
from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever which may at any time (including, without limitation, at any
time following the payment of the Notes) be imposed on, incurred by or asserted
against the Administrative Agent in any way relating to or arising out of this
Agreement or the other Loan Documents, or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Administrative Agent under or in
connection with any of the foregoing; provided that no Lender shall be liable
for the payment of any portion of such liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
resulting solely from the Administrative Agent's bad faith, gross negligence or
willful misconduct. The agreements in this Section 11.7 shall survive the
payment of the Notes, and all other amounts payable hereunder and the
termination of this Agreement.

         Section 11.8. The Administrative Agent in Its Individual Capacity. The
Administrative Agent and its respective Subsidiaries and Affiliates may make
loans to, accept deposits from and generally engage in any kind of business with
the Borrowers as though the Administrative Agent

                                       61
<PAGE>   68
were not an Administrative Agent hereunder. With respect to any Loans made or
renewed by it and any Note issued to it, the Administrative Agent shall have the
same rights and powers under this Agreement and the other Loan Documents as any
Lender and may exercise the same as though it were not an Administrative Agent,
and the terms "Lender" and "Lenders" shall include the Administrative Agent in
its individual capacity.

         Section 11.9. Resignation of the Administrative Agent; Successor
Administrative Agent. Subject to the appointment and acceptance of a successor
as provided below, the Administrative Agent may resign at any time by giving
notice thereof to the Lenders and the Borrowers. Upon any such resignation, the
Required Lenders shall have the right to appoint a successor Administrative
Agent, which successor shall be a financial institution chartered under the laws
of the United States of America or a state or commonwealth thereof and have
minimum capital and surplus of at least $500,000,000. If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within thirty (30) days after the
Administrative Agent's giving of notice of resignation, then the Administrative
Agent may, on behalf of the Lenders, appoint a successor Administrative Agent,
which successor shall be a financial institution chartered under the laws of the
United States of America or a state or commonwealth thereof and have minimum
capital and surplus of at least $500,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all rights, powers, privileges and duties of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations hereunder. After any retiring Administrative
Agent's resignation hereunder as Administrative Agent, the provisions of this
Section 11.9 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as Administrative Agent.

designates its office located at the address set forth above, or any subsequent

of or in any way connected with the Agreement, any other Loan Document or the
Loans or the transactions contemplated hereby, including without limitation
reasonable attorney's and consultant's fees, except to the extent that any of
the foregoing directly result from the gross negligence or willful misconduct of
the party seeking indemnification therefor.

         Section 12.3. Set-off. In addition to any rights now or hereafter
granted under Applicable Law and not by way of limitation of any such rights,
upon and after the occurrence of any Event of Default and during the continuance

or from time to time, without notice to the Borrowers or to any other Person,
any such notice being hereby expressly waived, to set off and to appropriate and

Obligations irrespective of whether or not (a) the Lenders shall have made any
demand under this Agreement or any of the other Loan Documents or (b) the

by, construed and enforced in accordance with the laws of the Commonwealth of

         Section 12.5. Consent to Jurisdiction. The Borrowers hereby irrevocably
consent to the personal jurisdiction of the state and federal courts located in

arising out of any dispute in connection with this Agreement, the Notes and the

performance of such rights and obligations. The Borrowers hereby irrevocably
consent to the service of a summons and complaint and other process in any
action, claim or proceeding brought by the Administrative Agent or any Lender in
connection with this Agreement, the Notes or the other Loan Documents, any
rights or obligations hereunder or thereunder, or the performance of such rights
and obligations, on behalf of itself or its property, in the manner specified in
Section 12.1. Nothing in this Section 12.5 shall affect the right of the

permitted by Applicable Law or affect the right of the Administrative Agent or
any Lender to bring any action or proceeding against the Borrowers or their
properties in the courts of any other jurisdictions.

         Section 12.6. Waiver of Jury Trial.

             (a) WAIVER OF JURY TRIAL. EACH OF THE PARTIES HERETO HEREBY
KNOWINGLY, VOLUNTARILY, AND INTENTIONALLY WAIVES ANY RIGHTS IT MAY HAVE TO A
TRIAL BY JURY IN RESPECT OF ANY LITIGATION BASED HEREON OR ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT OR THE NOTES OR ANY COURSE OF CONDUCT,
COURSE OF DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN) OR ACTIONS OF ANY LENDER
OR ADMINISTRATIVE AGENT. THIS PROVISION IS A MATERIAL INDUCEMENT FOR EACH
LENDER'S ENTERING INTO THIS AGREEMENT.

             (b) Preservation of Certain Remedies. The parties hereto and the
other Loan Documents preserve, without diminution, certain remedies that such
Persons may employ or exercise freely, either alone, in conjunction with or
during a dispute. Each such Person shall have and hereby reserves the right to
proceed in any court of proper jurisdiction or by self help to exercise or
prosecute the following remedies: (i) all rights to foreclose against any real
or personal property or other security by exercising a power of sale granted in
the Loan Documents

                                       66
<PAGE>   73

         Section 12.7. Reversal of Payments. To the extent a Borrower makes a
payment or payments to the Administrative Agent for the ratable benefit of the
Lenders or the Administrative Agent receives any payment or proceeds of the
collateral which payments or proceeds or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside and/or
required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, state or federal law, common law or equitable cause, then, to
the extent of such payment or proceeds repaid, the Obligations or part thereof
intended to be satisfied shall be revived and continued in full force and effect
as if such payment or proceeds had not been received by the Administrative
Agent.

         Section 12.8. Injunctive Relief; Punitive Damages.

             (a) Each Borrower recognizes that, in the event such Borrower fails
to perform, observe or discharge any of its obligations or liabilities under
this Agreement, any remedy of law may prove to be inadequate relief to the
Lenders. Therefore, each Borrower agrees that the Lenders, at the Lender's
option, shall be entitled to temporary and permanent injunctive relief in any
such case without the necessity of proving actual damages.

             (b) The Administrative Agent, Lenders and Borrowers (on behalf of
themselves and their Subsidiaries) hereby agree that no such Person shall have a
remedy of punitive or exemplary damages against any other party to a Loan
Document and each such Person hereby waives any right or claim to punitive or
exemplary damages that they may now have or may arise in the future in
connection with any dispute, whether such dispute is resolved through
arbitration or judicially.

         Section 12.9. Accounting Matters. All financial and accounting
calculations, measurements and computations made for any purpose relating to
this Agreement, including without limitation all computations utilized by any
Borrower or any Subsidiary thereof to determine compliance with any covenant
contained herein, shall, except as otherwise expressly contemplated hereby or
unless there is an express written direction by the Administrative Agent to the
contrary agreed to by a Borrower, be performed in accordance with GAAP.

             (e) Issuance of New Notes. Upon its receipt of an Assignment and
Acceptance executed by an assigning Lender and an Eligible Assignee together
with any Note or Notes subject to such assignment and the written consent to

with the provisions thereof) may be amended or waived by the Lenders, and any
consent given by the Lenders, if, but only if, such amendment, waiver or consent
is in writing signed by the Required Lenders (or by the Administrative Agent
with the consent of the Required Lenders) and delivered to the Administrative

no amendment, waiver or consent shall (a) increase the amount or extend the time

             The Borrowers' obligations under this Agreement and each of the
Loan Documents shall be performed by the Borrowers at their sole cost and
expense.

             All authorizations granted to the Lenders, the Administrative Agent
and any Persons designated by the Administrative Agent or any Lender pursuant to

deemed coupled with an interest and shall be irrevocable so long as any of the
Obligations remain unpaid or unsatisfied or the Working Capital Facility has not
been terminated.

             Notwithstanding any termination of this Agreement, the indemnities
to which the Administrative Agent and the Lenders are entitled under the

Exhibit 99

CAUTIONARY STATEMENTS PURSUANT TO THE SECURITIES
LITIGATION REFORM ACT OF 1995

The Company wishes to inform its investors of the following important factors
that in some cases have affected, and in the future could affect, the Company's
results of operations and that could cause such future results of operations to
differ materially from those expressed in any forward looking statements made by
or on behalf of the Company. Disclosure of these factors is intended to permit
the Company to take advantage of the "safe harbor" provisions of the Private
Securities Litigation Reform Act of 1995. Many of these factors have been
discussed in prior SEC filings by the Company. Though the Company has attempted
to list comprehensively these important cautionary factors, the Company wishes
to caution investors that other factors may in the future prove to be important
in affecting the Company's results of operations.

Demand Variability -- Demand for new equipment manufactured by the Company tends
to be cyclical, responding historically to varying levels of construction and
industrial activity, principally in the United States and, to a lesser extent,
in other industrialized nations. Other factors affecting demand include the
availability and cost of financing for equipment purchases, the market
availability of used equipment and alternatives to purchases such as equipment
leases directly from the Company. Company management regularly monitors these
and other factors that affect demand for the Company's equipment. However,
predicting levels of demand beyond a short term is necessarily imprecise and
demand may at times change dramatically.

Consolidating Customers Base; Rental Companies -- The principal customers for
the Company's new equipment are independent equipment rental companies that rent
the Company's products and provide service support to equipment users. In recent
years, growth in sales to equipment rental companies has outpaced growth in
direct sales to end-users, resulting in equipment rental companies comprising a
larger share of total sales. At the same time, there has been substantial
consolidation in ownership among rental companies, resulting in a more limited
number of major customers comprising a substantial portion of total sales. A
change in purchasing decisions or ordering patterns by any of these major
customers could materially affect overall demand for the Company's products and
the Company's financial performance. More generally, during recessionary
conditions, demand for equipment by equipment rental companies typically
declines more sharply than demand for equipment purchased by end-users. The
Company believes it is a preferred supplier to certain equipment rental
companies whose continued business depends upon a package of products and
services including financing, e-commerce ordering, just-in-time delivery,
enhanced warranties, used equipment trade-ins and other customer services and
after market support.

Competition; Continued Innovation -- The Company faces substantial competition
in the market for its products. Product line expansion by existing competitors
and potential entry by new competitors also may affect the Company's market
position. Throughout its history, the Company has devoted substantial resources
to product development and has generally succeeded in being a market leader in
introducing new products or incorporating new features and functions into
existing products. Successful product innovation by competitors that reach the
market prior to comparable innovation by the Company or that are amenable to

Product Liability -- Use of the Company's products involves risks of personal
injury and property damage and liability exposure for the Company. The Company
insures against this liability through a combination of a self-insurance
retention and catastrophic insurance coverage in excess of the retention. The
Company monitors all incidents of which it becomes aware involving the use of
its products that result in personal injury or property damage and establishes
accrued liability reserves on its financial statements based on liability
estimates with respect to claims arising from such incidents. Future or
unreported incidents involving personal injury or property damage or
unanticipated variances between actual liabilities for known incidents and
Company estimates may adversely affect the Company's financial performance.

Manufacturing Capacity; Production Levels -- Given the variability of demand,
the Company must periodically expand and contract its manufacturing facilities.
Capital investment to acquire additional manufacturing facilities involves
significant risks. Excess manufacturing capacity adversely affects profitability
because higher fixed costs are spread over a lower sales volume. Insufficient
capacity adversely affects profitability as long lead-times required to fill
customer orders may impair the Company's ability to compete for new business and
subcontracting costs incurred to increase capacity affect profitability. To
ensure product availability, the Company sometimes manages inventory levels and
its supply chain by maintaining relatively constant production levels. This
practice could increase inventories and associated carrying costs which could
adversely affect the Company's financial performance.

Availability of Product Components -- The Company obtains raw materials and
certain manufactured components from third-party suppliers. To reduce material
costs and inventories, the Company relies on supplier partnership arrangements
with preferred vendors as a sole source for "just-in-time" delivery of many raw
materials and manufactured components. Because the Company maintains limited raw
material inventories, even brief unanticipated delays in delivery by suppliers,
including those due to capacity constraints, labor disputes, impaired financial
condition of suppliers, weather emergencies or other natural disasters, may
adversely affect the Company's ability to satisfy its customers on a timely
basis and thereby affect the Company's financial performance.

Foreign Sales; Currency Risks -- A growing component of the Company's business
has been export sales to Europe, Australia, Latin America, Africa and Asia.
Maintenance and continued growth of this segment of the Company's business may
be affected by changes in trade, monetary and fiscal policies, laws and
regulations of the United States and other trading nations and by foreign
currency exchange rate fluctuations and the ability or inability of the Company
to hedge against exchange rate risks.

Mergers and Acquisitions -- The Company intends to pursue strategic acquisitions
as a means of increasing sales and earnings and promoting shareholder value.
Acquisitions generally may involve a number of risks that may affect the
Company's financial performance including increased leverage, diversion of
management resources, possible shareholder dilution, assumption of liabilities
of acquired businesses and corporate culture conflicts. In addition, specific
acquisitions may involve other risks unique to the acquired business. Finally,
there is no assurance that the Company will be able to conclude satisfactory
agreements to acquire any businesses as a means to increase sales and earnings.

Unanticipated Litigation -- The Company occasionally has faced unanticipated
intellectual property and shareholder litigation which has involved significant
unbudgeted expenditures. The costs and other effects of any future,
unanticipated legal or administrative proceedings may be significant.

Dependence Upon Key Personnel; Management Recruitment -- The Company believes
that it has developed a strong management team, which intends to continue the
Company's growth and profitability. However, the loss or unavailability of
certain key management personnel and the inability to attract, assimilate or
retain additional highly qualified employees in the future could adversely
affect the Company's business and prospects.
