Item 2.  Acquisition or Disposition of Assets

         (a) On June 18, 1999, JLG Industries, Inc. (the Company) completed the
         merger of its wholly owned subsidiary with and into Gradall Industries,
         Inc. (Gradall). Following its tender offer, the Company acquired 100%
         or 9,834,871 voting common shares of Gradall for $20.00 per share.
         Shares of Gradall common stock not tendered in the tender offer were
         converted into the right to receive $20.00 per share in cash. The
         acquisition was financed by the proceeds from the revolving credit
         facility described in Item 5 (a) below.

         (b) Gradall is a leading manufacturer of rough-terrain, variable-reach
         material handlers and telescoping hydraulic excavators used in
         infrastructure, residential, non-residential and institutional
         construction and is one of the industry's most recognized brand names.


Item 5.  Other Events

         (a) The Company entered into a Credit Agreement dated June 18, 1999
         (the "Credit Agreement") by and among the Company, certain of its
         subsidiaries, and certain financial institutions named therein. The
         Credit Agreement provides for a five year revolving credit facility,
         with an aggregate commitment of $250 million. The Credit Agreement
         commitment is available for the costs of the acquisition, repaying
         pre-acquisition indebtedness and working capital and general corporate
         purposes.

         Borrowings under the Credit Agreement bear interest at a rate per annum
         equal to, at the Company's option, either LIBOR plus a margin ranging
         from .55% to 1.125%, depending on the Company's ratio of funded debt to
         EBITDA, or the greater of prime rate or federal funds rate plus .50%.
         The Company is also required to pay an underwriting fee of .75% of the
         commitment and an annual administrative fee of $35,000, and a facility
         fee ranging from .20% to .275%, depending on the Company's ratio of
         funded debt to EBITDA. The Credit Agreement contains customary
         affirmative and negative covenants, including financial covenants
         requiring the maintenance of specific consolidated interest coverage
         and leverage ratios and a minimum consolidated net worth.

         (b) On June 18, 1999, the Company modified an existing credit agreement
         to reduce the maximum borrowing amount from $40 million to $20 million.

                (dollars in thousands, except per share amounts)

1.       NATURE OF BUSINESS AND BASIS OF PRESENTATION:

Gradall Industries, Inc. (the "Company"), Incorporated in Delaware, formerly ICM
Industries Inc. (ICM), is a holding Company. The consolidated financial
statements include the Company and its wholly owned subsidiaries, The Gradall
Company, The Gradall Orrville Company and Gradall Investment Company. The
Gradall Investment Company was dissolved in 1996.

The Gradall Company manufactures and sells excavating and material handling
equipment and related parts to public and private sector customers throughout
the world through independent distribution organization.

On September 3, 1996, the Company completed an initial public offering in which
2,950,000 shares of common stock were issued for a total sum of $29.5 million.
Expenses incurred in connection with the issue approximated $2.6 million. The
net proceeds of the offering were used as follows:

<TABLE>
<S>                                                     <C>
Repay outstanding term debt                             $ 9,550

Repay subordinate debt                                   10,000

Redeem preferred stock.                                   2,000

Reduce revolving credit liability                         5,379
</TABLE>

In connection with the offering, the Company increased the number of its
authorized shares of common stock from 2,200 to 18,000,000 and effected a
5,540-to-1 stock split. All applicable share and per share data have been
retroactively adjusted for the stock split.

On June 29, 1998, the Company completed a public offering in which 562,500
shares of common stock were issued by the Company for a total sum of $7.3
million. Expenses incurred in connection with the issue approximated $0.5
million including $0.1 million related to selling shareholders. The net proceeds
of the offering were used to repay the revolving credit facility.

On October 13, 1998, a new company, The Gradall Orrville Company, was formed as
a wholly owned subsidiary of Gradall Industries, Inc., to purchase a new
production plant at Orrville, Ohio. The new facility, formerly the Volvo Truck
Assembly plant, contains 330,000 square feet and will provide additional
production space for the material handler product.

                   Notes to Consolidated Financial Statements
                (dollars in thousands, except per share amounts)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Principles of Consolidation: The accompanying consolidated financial statements
include the accounts of the Company and its wholly owned subsidiaries. All
significant intercompany accounts and transactions have been eliminated.

Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the amounts reported in the financial statements and
related notes. Actual results may differ from those estimates.

Source of Supply of Labor: Virtually all of the Company's hourly employees are
represented by the International Association of Machinists and Aerospace Workers
under a three-year contract which expires April 16, 2000.

Revenue Recognition: The Company's revenue recognition policy is to recognize
revenue when products are shipped. In 1998, the Company entered into a
twelve-month lease agreement for certain inventories which includes a guarantee
by the Company at the end of the lease agreement. Revenues equal to the amount
of the guarantee are deferred.

Product Financing: The Company provides its distributors with product financing
through agreements with third party financing companies. Such financings include
a Wholesale Floor Plan for distributors and a Retail Finance Plan for end-users,
each with reduced interest rates subsidized by the Company, and a Rental Plan
for distributors.

Product Warranty Costs: In general, the Company provides warranty on equipment
for a period of up to twelve months or for a specified period of use after sale
or rental by the distributor. Reserves for estimated warranty costs are
established at the time of sale.

Inventories: Inventories are stated at cost not in excess of market value using
the last-in, first-out (LIFO) method of inventory costing. Inventory cost
includes materials, direct labor, manufacturing overhead, and outside service
costs. Market value is determined by comparison with recent purchases or
realizable value.

Property, Plant and Equipment: Expenditures for property, plant and equipment
and for renewals and betterments which extend the originally estimated economic
lives of assets are capitalized at cost. Expenditures for maintenance and
repairs are charged to expense. Items which are sold, retired, or otherwise
disposed of are removed from the asset and accumulated depreciation accounts and
any gains or losses are reflected in income. The Company's depreciation and
amortization methods are as follows:

Buildings and improvements                           10 - 24 years                          Straight-line
Furniture and fixtures                                3 - 10 years                          Straight-line
</TABLE>

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

Deferred Financing Costs: Costs incurred to obtain financing have been
capitalized and are being amortized over the life of the respective financing
arrangements.

Income Taxes: The Company follows the provisions of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes." Deferred income
taxes arise from reporting certain items of income and expense for tax purposes
in a different period than for financial reporting purposes.

Fair Value of Financial Instruments: The Company's financial instruments consist
principally of cash, accounts receivable, accounts payable and accrued
liabilities in which the fair value of these financial instruments approximates
the carrying value. The Company's revolving line of credit provides for periodic
changes in interest rates which approximate current rates and therefore, the
fair value of the debt approximates carrying value.

Research and Development Costs: Expenditures relating to the development of new
products and processes, including significant improvements to existing products,
are expensed as incurred. Research and development expenses were $2,552, $1,722
and $1,641 in 1998, 1997 and 1996, respectively. In addition, the Company
incurred other engineering expenses relating to new product development (that do
not meet the accounting definition of "Research and Development") in the amount
of $1,487, $1,922 and $1,440 in 1998, 1997 and 1996, respectively.

Stock Based Compensation: The Company accounts for stock based compensation
awards pursuant to Accounting Principles Board Opinion No. 25, "Accounting for
Stock Issued to Employees," and its related interpretations which prescribe the
use of the intrinsic value based method. No compensation cost has been
recognized for its fixed stock option plans. However, the Company has adopted
the disclosure requirements of Statement of Financial Accounting Standards No.
123, "Accounting for Stock Based Compensation," See Note 10 for additional
information.

Earnings Per Common Share: In the fourth quarter of 1997, the Company adopted
the provisions of Statement of Financial Accounting Standards No. 128 ("SFAS
128"), "Earnings per Share," which specifies the computation, presentation, and
disclosure requirements of earnings per common share. Basic earnings per share
are based on the weighted average number of common shares outstanding during the
period. Diluted earnings per common share are based on the weighted average
number of common shares outstanding during the period plus, if dilutive, the
incremental number of common shares issuable on a pro forma basis upon the
exercise of employee stock options, assuming the proceeds are used to repurchase
outstanding shares at the average market price during the year. All prior
periods have been restated to conform to the provisions of this statement. A
reconciliation of the Basic and Diluted per share computations are provided
below:

</TABLE>

Comprehensive Income: Statement of Financial Accounting Standards No. 130,
"Reporting Comprehensive Income." was adopted during the first quarter of 1998.
The standard established guidelines for the reporting and display of
comprehensive income (loss) and its components in financial statements.
Comprehensive income includes net income and adjustments to the minimum pension
liability. The Company has changed the format of its Consolidated Statement of
Changes in Stockholders' Equity to present comprehensive income and its
components.

Segment Information: Statement of Financial Accounting Standards No. 131,
"Disclosures about Segments of an Enterprise and Related Information," was
adopted in the fourth quarter of 1998 and supersedes Statement of Financial
Accounting Standards No. 14, "Financial Reporting for Segments of a Business
Enterprise." The new standard established guidelines for reporting information
on operating segments in interim and annual financial statements. The adoption
of the standard did not affect the Company's financial position, results of
operations or cash flows (see Note 14).

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES, CONTINUED:

Future Accounting Requirements: In June 1998, the Financial Accounting Standards
Board issued Statement of Financial Accounting Standards No. 133, "Accounting
for Derivative Instruments and Hedging Activities." This Statement requires that
all derivative instruments be recorded on the balance sheet at their fair value.
Changes in the fair value of derivatives will be recorded each period in current
earnings or other comprehensive income. The new rules will be effective the
first quarter of 2000. The Company is in the process of determining the impact

At December 31, 1998, the Company maintained a loan and security agreement with
Heller Financial, Inc. which provided for up to $25 million in revolving loan
commitments. Amounts borrowed under the borrowing base, as defined, could be
repaid and reborrowed at any time prior to August 31, 1999, the termination
date. Amounts outstanding under this agreement were reclassified to current
portion of long-term debt at December 31, 1998.

5.  FINANCING, CONTINUED:

The revolving line of credit bears interest at either LIBOR plus 1% or prime
minus .50%. At December 31, 1998, the prime rate was 7.75%. There were no
borrowings under the LIBOR option at year end. The average annual interest rate
in effect for the revolving line of credit was 7.25%. At December 31, 1997, the
prime rate was 8.5%, LIBOR was 5.97%, and the average annual interest rate in
effect for the revolving line of credit was 7.86%. The Company also pays an
unused line fee of 0.25 percent per annum.

The terms of the financing agreement contain, among other provisions,
restrictions on the level of capital expenditures and various financial ratios,
as defined. The financing agreements are collateralized by substantially all the
assets of the Company.

On January 27, 1999 the Company's Loan and Security Agreement with Heller
Financial, Inc. was paid in full and terminated. A new revolving line of credit
for $17 million was established with KeyBank National Association (the "Lender")
with an unsecured demand promissory note. The note bears interest at either
LIBOR plus .80% or prime minus 1.40%. The note renews annually and terminates at
the earlier of the Lender's demand or the Company's decision to terminate by
written or oral communication to the Lender.

6.  LEASE  OBLIGATIONS

The Company leases certain machinery and equipment under capital leases expiring
between 1999 and 2001. The assets and liabilities under capital leases are
recorded at the original purchase cost. The assets are depreciated over their
estimated productive lives. Depreciation of assets under capital leases is
included in depreciation expense.

In addition, the Company leases certain equipment under operating leases. A
number of these leases have renewal options.

The following is a summary of property held under capital leases:

Rental expense for operating leases amounted to $394, $409 and $397 for the

7.   EMPLOYEE BENEFIT PLANS:

Pension and Postretirement Benefit Plans: Substantially all employees are
covered by pension plans which provide for monthly pension payments to eligible
former employees who have retired. Prior to March 24, 1997 the Company sponsored
two plans, one for members of the collective bargaining unit and one for
salaried and other eligible employees.

Benefits paid under the collective bargaining unit plan are based on a benefit
multiplier times years of credited service, reduced by benefits under a prior
plan. Such prior plan benefits are guaranteed under the terms of group annuity
contracts. Benefits paid under the salary plan are based on the greater of a
benefit multiplier times years of credited service or a percentage of
pre-retirement earnings. Pension costs are funded as actuarially determined and
to the extent cash contributions are deductible for federal income tax purposes.
The collective bargaining unit plan uses the entry age normal actuarial cost
method to determine annual contributions to the plan. The salary plan uses the
unit credit actuarial cost method to determine contributions.

7.  EMPLOYEE BENEFIT PLANS, CONTINUED:

Effective March 24, 1997 the Company adopted the IAM National Pension Plan to
replace the existing collective bargaining unit plan for future service
benefits. The collective bargaining unit plan benefits were frozen and the
Company continues to fund the plan for past service benefits. The expense
related to funding the IAM National Pension Plan for years ending December 31,
1998 and 1997 was $371 and $254 respectively.

Postretirement Benefits: The Company provides eligible retired employees with
health care and life insurance benefits. These benefits are provided on a
non-contributory basis for life insurance and contributory basis for medical
coverage. Currently, the Company does not pre-fund these benefits.

Statement of Financial Accounting Standards No. 87, "Employers' Accounting for
Pension," contains a provision which requires the recognition of a liability
(including unfunded accrued pension costs) that is at least equal to the
unfunded accumulated benefit obligation (the excess of the accumulated benefit
obligation over the fair value of plan assets). Recognition of an additional
minimum liability is required if an unfunded accumulated benefit exists and the
liability already recognized as unfunded accrued pension cost is less than the
unfunded accumulated benefit obligation. The additional minimum liability of
$1,160 and $980 at December 31, 1998 and 1997, respectively, has been included
in other long-term liabilities and has been reported net of income tax effect
within stockholders' equity.

The following table sets forth the both plan's funded status and amounts
recognized in the Company's consolidated financial statements.

For measurement purposes, an 8 percent annual rate increase in the per capita
cost of covered health care benefits was assumed for 1998. The rate was assumed
to decrease gradually to 5 percent by 2011 and remain at that level hereafter.
Assumed health care cost trend rates have a significant effect on the amounts
reported for the health care plan. A one-percent point change in assumed health
care cost trend rates would have the following effects:

Savings and Investment Plan: Substantially all employees are eligible to
participate in a savings and investment plan. The Company sponsors two plans,
one for members of the collective bargaining unit and one for salaried and other
eligible employees. The plans provide for contributions by employees, through
salary reductions, and for a matching contribution by the Company based on a
rate determined for each plan year by the Board of Directors of the Company. The
plans also provide for a discretionary contribution by the Company. No Company
contributions were made to the plan in 1998, 1997 or 1996.

Deferred Compensation Program: The Company has a deferred compensation program
under which certain employees may elect to postpone receipt of a portion of
their earnings. The amounts so deferred are deposited in a trust account, but
remain assets of the Company. The trustees of the program are officers and a key
employee of the Company.

The Company is authorized to issue shares of Series A preferred stock in which
each share has one vote with a fixed aggregate of 12% of the total vote. The
holders of this preferred stock will vote together with the holders of the
Company's common stock on all matters submitted to the Company's stockholders.
Holders may require the Company to redeem preferred shares proportionately to
any reduction in shares held by MLGA Fund II, L.P. At December 31, 1998 and 1997
no Series A preferred stock was outstanding.

The Board of Directors is authorized, subject to any limitations prescribed by
law, to issue preferred stock in one or more classes or series and to fix the
designations, voting powers, preferences, rights, qualifications, limitations or
restrictions of any such class or series, including dividend rights, dividend
rates, redemption prices and terms, conversion rights and liquidation
preferences of each class or series of preferred stock, without any further vote
or action by the stockholders of the Company.

10.  STOCK OPTIONS:

On October 13, 1995, the stockholders approved a qualified incentive stock
option program under which 315,226 shares of the Company's common stock are
reserved for grants to key employees (The "1995 Stock Option Plan"). The option
price is to be determined by the Board, but may not be less than 100% of the
fair market value of the Company's common stock at the time of the grant and
options must be exercised within ten years from the date of grant. The options
vest and become exercisable in three annual installments commencing on the first
anniversary of the date of the grant. On June 3, 1997, the stockholders approved
an amendment to the 1995 Stock Option Plan increasing the number of shares of
the Company's common stock reserved for grants under the program to 515,226.

On May 20, 1998, the stockholders approved a qualified incentive stock option
plan under which 300,000 shares of the Company's common stock are reserved for
grants to key employees. The plan includes provisions for pricing and vesting
which are the same as the above plan. The stockholders also approved an employee
stock purchase plan under which 300,000 shares of the Company's common stock may
be sold at a 15% market price reduction. Common shares sold through the plan are
being purchased in the open market.

10.  STOCK OPTIONS, CONTINUED:

In October 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation." This statement defines a fair value based method of accounting
for an employee stock option or similar equity instrument. The statement does,
however, allow an entity to continue to measure compensation cost for those
plans using the intrinsic value based method of accounting prescribed by
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued To
Employees."

In 1996, the Company adopted provisions of SFAS No. 123 by providing disclosures
of the pro forma effect on net income and earnings per share that would result
if the fair value compensation element were to be recognized as expense. The
following table shows the pro forma earnings and earnings per share for 1998,
1997 and 1996 along with significant assumptions used in determining the fair
value of the compensation amounts.

granted in 1998.

11.      CONTINGENCIES:

The Company is involved in certain claims and litigation related to its
operations. Based upon the facts known at this time, management is of the
opinion that the ultimate outcome of all such claims and litigation will not
have a material adverse effect on the financial condition, results of operations
or cash flows of the Company.

13.  EXTRAORDINARY ITEM:

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

14.  SEGMENT REPORTING:

During the fourth quarter of 1998, the Company adopted Statement of Financial
Accounting Standard No. 131, "Disclosure about Segments of an Enterprise and
Related Information." Management has determined that the Company operates in a
single industry segment, construction equipment. The Company's operations
involve manufacturing specialized construction equipment and parts. While the
Company's chief operating decision maker monitors the revenue streams of the
different products, operations are managed and financial performance is measured
in the construction equipment segment.

                        Report of Independent Accountants



TO THE BOARD OF DIRECTORS AND STOCKHOLDERS OF GRADALL INDUSTRIES, INC.

In our opinion, the accompanying consolidated balance sheets and related
consolidated statements of income, changes in stockholders' equity and cash
flows present fairly, in all material respects, the financial position of
Gradall Industries, Inc. and its subsidiaries (the "Company") at December 31,
1998 and 1997, and the results of their operations and their cash flows for each
of the three years in the period ended December 31, 1998, in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

        NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                (DOLLARS IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

1.  BASIS OF PRESENTATION:

The unaudited interim financial information as of March 31, 1999 and for the
three months ended March 31, 1999 and 1998 has been prepared on the same basis
as the audited financial statements. In the opinion of management such unaudited
information includes all adjustments (consisting only of normal recurring
adjustments) necessary for a fair presentation of the interim information.
Operating results for the three months ended March 31, 1999 are not necessarily
indicative of the results that may be expected for the entire year ending
December 31, 1999.

These financial statements and the notes thereto should be read in conjunction
with the Company's audited financial statements included in its Annual Report or
Form 10-K for the fiscal year ended December 31, 1998.

2.  OTHER COMPREHENSIVE INCOME:

The Company has no significant items of other comprehensive income.

3.  NEW ACCOUNTING STANDARDS:

In March 1998 the Accounting Standards Executive Committee issued Statement of
Position ("SOP") 98-1, "Accounting for the Costs of Computer Software Developed
or Obtained for Internal Use," which is effective for financial years beginning
after December 15, 1998. The Company adopted the provisions of this SOP
beginning January 1, 1999, which had no significant effect on the Company's
consolidated financial statements.

4. INVENTORIES:

Inventories were comprised of

6.  FINANCING:

In January 1999 the Company's Loan and Security Agreement with Heller Financial,
Inc. was paid in full and terminated. A new revolving line of credit for $17
million was established with KeyBank National Association (the "Lender") with an
unsecured demand promissory note. At March 31, 1999, borrowing under the new
revolving credit facility totaled $10.8 million, and $4.2 million was available
under the facility. On April 21, 1999 the revolving line of credit with KeyBank
was increased to $22 million,. The note bears interest at either LIBOR plus .80%
or prime minus 1.40%. The note renews annually and terminates at the earlier of
the Lender's demand or the Company's decision to terminate by written or oral
communication to the Lender.

7.  CONTINGENCIES:

The Company is involved in certain claims and litigation related to its
operations. Based upon the facts known at this time, management is of the
opinion that the ultimate outcome of all such claims and litigation will not
have a material adverse effect on the financial condition, results of operations
or cash flows of the Company.

8.  NEW COMPANY:

On October 13, 1998, a new company, The Gradall Orrville Company, was formed as
a wholly owned subsidiary of Gradall Industries, Inc., to purchase a new
production plant at Orrville, Ohio. The new facility, formerly the Volvo Truck
Assembly plant, contains 330,000 square feet and will provide additional
production space for the material handler product.

The unaudited pro forma combined financial statements give retroactive effect to

of the Company's 1998 fiscal year, and are based on the allocated purchase price
as reported in the pro forma combined balance sheet at April 30, 1999.

The purchase price for the acquisition of Gradall was $208,194 including
expenses of $6,700. The purchase price was allocated as follows:

      INTRODUCTION TO THE UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS
                                   (CONTINUED)
                             (DOLLARS IN THOUSANDS)


The value of goodwill will be amortized over a twenty-five year period, and will
be reviewed if the facts and circumstances suggest that the value of the
goodwill is impaired, based on analysis of future cash flows from the Gradall
business. If this review indicates that the goodwill will not be recoverable,
the Company's carrying value of the goodwill will be reduced accordingly.

These unaudited pro forma combined financial statements may not be indicative of
the results that may be obtained in the future. The unaudited pro forma combined
financial statements, including the notes thereto, should be read in conjunction
with the historical financial statements of the Company and Gradall.

The Company has a fiscal year end of July 31st while Gradall has a year end of
December 31st. For purposes of preparing these pro forma unaudited combined
financial statements, an annual twelve month period end of July 31, 1998 and
June 30, 1998 was utilized for the Company and Gradall, respectively. In
addition, a nine month period end of April 30, 1999 and March 31, 1999 was
utilized for the Company and Gradall, respectively. Management of the Company
does not believe that the results of operations reported on the same fiscal
period end as the Company and Gradall would be materially different than as
reported using the aforementioned period ends.

         B. Swingline Loans

                  a. Availability. Subject to the terms and conditions of this
Agreement, the Swingline Lender agrees to make Swingline Loans to the Borrowers
from time to time from the Closing Date through, but not including, the
Swingline Termination Date; provided, that the



                                      -15-
<PAGE>   17

aggregate principal amount of all outstanding Swingline Loans (after giving
effect to any amount requested), shall not exceed the lesser of (i) the
Aggregate Commitment less the sum of all outstanding Revolving Credit Loans and
the L/C Obligations and (ii) the Swingline Commitment. The obligations of
Borrowers under the Swingline Loans are and shall be joint and several.

                  b. Refunding.

                           (1) Swingline Loans shall be refunded by the Lenders
on demand by the Swingline Lender. Such refundings shall be made by the Lenders
in accordance with their respective Commitment Percentages and shall thereafter
be reflected as Revolving Credit Loans of the Lenders on the books and records
of the Administrative Agent. Each Lender shall fund its respective Commitment
Percentage of Revolving Credit Loans as required to repay Swingline Loans
outstanding to the Swingline Lender upon demand by the Swingline Lender but in
no event later than 2:00 p.m. (Philadelphia time) on the next succeeding
Business Day after such demand is made. No Lender's obligation to fund its
respective Commitment Percentage of a Swingline Loan shall be affected by any
other Lender's failure to fund its Commitment Percentage of a Swingline Loan,
nor shall any Lender's Commitment Percentage be increased as a result of any
such failure of any other Lender to fund its Commitment Percentage.

                           (2) The Borrowers shall pay to the Swingline Lender
within one (1) Business Day following demand the full amount of such outstanding
Swingline Loans if amounts received from the Lenders other than the Swingline
Lender are not sufficient to repay in full the portion of the outstanding
Swingline Loans in excess of the Commitment Percentage of the Swingline Lender
(the "Excess Swingline Amount") requested or required to be refunded. In
addition, the Borrowers hereby authorize the Administrative Agent to charge any
account maintained with the Swingline Lender (up to the amount available
therein) in order to immediately pay the Swingline Lender the amount of such
Swingline Loans to the extent amounts received from the Lenders are not
sufficient to repay in full the Excess Swingline Amount requested or required to
be refunded. If any portion of any such amount paid to the Swingline Lender
shall be recovered by or on behalf of the Borrowers from the Swingline Lender in
bankruptcy or otherwise, the loss of the amount so recovered shall be ratably
shared among all the Lenders in accordance with their respective Commitment
Percentages (unless the amounts so recovered by or on behalf of the Borrowers
pertain to a Swingline Loan extended after the occurrence and during the
continuance of an Event of Default of which the Administrative Agent has
received actual notice and which such Event of Default has not been waived by
the Required Lenders or the Lenders, as applicable).

                           (3) Each Lender acknowledges and agrees that its
obligation to refund Swingline Loans in accordance with the terms of this
Section 2.2 is absolute and unconditional and shall not be affected by any
circumstance whatsoever, including, without limitation, non-satisfaction of the
conditions set forth in Article V. Further, each Lender agrees and acknowledges
that if prior to the refunding of any outstanding Swingline Loans pursuant to
this Section 2.2, one of the events described in Section 11.1(j) or (k) shall
have occurred, each Lender



                                      -16-
<PAGE>   18

will, on the date the applicable Revolving Credit Loan would have been made,
purchase an undivided participating interest in the Swingline Loan to be
refunded in an amount equal to its Commitment Percentage of the aggregate amount
of such Swingline Loan. Each Lender will immediately transfer to the Swingline
Lender, in immediately available funds, the amount of its participation and upon
receipt thereof the Swingline Lender will deliver to such Lender a certificate
evidencing such participation dated the date of receipt of such funds and for
such amount. Whenever, at any time after the Swingline Lender has received from
any Lender such Lender's participating interest in a Swingline Loan, the
Swingline Lender receives any payment on account thereof, the Swingline Lender
will distribute to such Lender its participating interest in such amount
(appropriately adjusted, in the case of interest payments, to reflect the period
of time during which such Lender's participating interest was outstanding and
funded).

         C. Procedure for Advances of Revolving Credit and Swingline 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 each
Swingline 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, (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 and (z) with
respect to Swingline Loans in an aggregate principle amount of $500,000 or a
whole multiple of $100,000 in excess thereof, (C) whether such Loan is to be a
Revolving Credit Loan or Swingline Loan, (D) in the case of a Revolving Credit
Loan whether the Loans are to be LIBOR Rate Loans or Base Rate Loans, and (E) 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 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.



                                      -17-

                  c. Disbursement of Revolving Credit and Swingline Loans. Not
later than 2:00 p.m. (Philadelphia time) on the proposed borrowing date, (i)
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 Revolving Credit Loans to be made on such borrowing date and (ii) the
Swingline 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, the Swingline 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 2.3 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 4.7 hereof, the Administrative Agent shall
not be obligated to disburse the portion of the proceeds of any Revolving Credit
Loan requested pursuant to this Section 2.3 to the extent that any Lender has
not made available to the Administrative Agent its Commitment Percentage of such
Loan. Revolving Credit Loans to be made for the purpose of refunding Swingline
Loans shall be made by the Lenders as provided in Section 2.2(b).

         D. Repayment of Loans

                  a. Repayment on Termination Date. The Borrowers shall repay
the outstanding principal amount of (i) all Revolving Credit Loans in full on
the Termination Date, and (ii) all Swingline Loans in accordance with Section
2.2(b), together, in each case, 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 less
the sum of all outstanding L/C Obligations and Swingline Loans, the Borrowers
shall repay immediately upon notice from the Administrative Agent, by payment to
the Administrative Agent for the account of the Lenders, Revolving Credit Loans
and Swingline Loans, and furnish cash collateral reasonably satisfactory to the
Administrative Agent and/or repay the L/C Obligations in an amount equal to such
excess with each such repayment applied first to the principal amount of
outstanding Swingline Loans, second to the principal amount of the L/C
Obligations and third to the principal amount of outstanding Revolving Credit
Loans. Such cash collateral shall be applied in accordance with Section 11.2(b).
Each such repayment shall be accompanied by any amount required to be paid
pursuant to Section 4.9 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



                                      -18-
<PAGE>   20

notice with respect to Base Rate Loans and Swingline 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,
Swingline Loans or a combination thereof, and, if of a combination thereof, the
amount allocable to each. Upon receipt of such notice, the 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, $3,000,000 or a whole multiple of $1,000,000 in excess
thereof with respect to LIBOR Rate Loans and $500,000 or a whole multiple of
$100,000 in excess thereof with respect to Swingline Loans. Each such repayment
with respect to any LIBOR Rate Loan shall be accompanied by any amount required
to be paid pursuant to Section 4.9 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 4.9 hereof.

         E. Notes

                  a. Revolving Credit Notes. Each Lender's Revolving Credit
Loans and the obligation of the Borrowers to repay such Revolving Credit Loans
shall be evidenced by separate Revolving Credit 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 Revolving Credit 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 Revolving Credit 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 4.1.

                  b. Swingline Notes. The Swingline Loans and the obligations of
the Borrowers to repay such Swingline Loans shall be evidenced by a Swingline
Note executed by the Borrowers payable to the order of the Swingline Lender,
representing the Borrowers' obligation to pay the Swingline Lender's Swingline
Commitment or, if less, the aggregate unpaid principal amount of all Swingline
Loans made by the Swingline Lender to the Borrowers hereunder, plus interest on
such principal amounts and all other fees, charges and other amounts due thereon
in accordance with the terms of this Agreement or any other Loan Document. The
Swingline 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 4.1.



                                      -19-
<PAGE>   21

         F. 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
2.6 shall be accompanied by a payment of principal sufficient to reduce the
aggregate outstanding Extensions of Credit of the Lenders after such reduction
to the Aggregate Commitment as so reduced and if the Aggregate Commitment as so
reduced is less than the aggregate amount of all outstanding Letters of Credit,
the Borrowers shall be required to deposit in a cash collateral account opened
by the Administrative Agent an amount equal to the aggregate then undrawn and
unexpired amount of such Letters of Credit. Any reduction of the Aggregate
Commitment to zero shall be accompanied by payment of all outstanding
Obligations (and furnishing of cash collateral satisfactory to the
Administrative Agent for all L/C Obligations) and shall result in the
termination of the Commitments and Credit Facility. Such cash collateral shall
be applied in accordance with Section 11.2(b). 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 4.9 hereof.

         G. Termination of Credit Facility The Credit Facility shall terminate
on the Termination Date.

         H. Use of Proceeds The Borrowers shall use the proceeds of the
Extensions of Credit (a) to fund the purchase of an amount of shares of common
stock of Gradall which constitutes more than 50% of the voting power of Gradall,
(b) to refinance certain existing indebtedness, and (c) for working capital and
general corporate requirements of the Borrowers and their Subsidiaries,
including without limitation the payment of certain fees and expenses incurred
in connection with the transactions contemplated hereby.

III.                        LETTER OF CREDIT FACILITY

         A. L/C Commitment. Subject to the terms and conditions hereof, the
Issuing Lender, in reliance on the agreements of the other Lenders set forth in
Section 3.4(a), agrees to issue standby letters of credit ("Letters of Credit")
for the account of the Borrowers on any Business Day from the Closing Date
through but not including the Termination Date in such form as may be approved
from time to time by the Issuing Lender; provided, that the Issuing Lender shall
have no obligation to issue any Letter of Credit if, after giving effect to such
issuance, (a) the L/C Obligations would exceed the L/C Commitment or (b) the
Available Commitment of any Lender would be less than zero. Each Letter of
Credit shall (i) be denominated in Dollars in a minimum amount of $100,000,



                                      -20-
<PAGE>   22

(ii) be a standby letter of credit issued to support obligations of any Borrower
or any Subsidiary, contingent or otherwise, incurred in the ordinary course of
business, (iii) expire on a date no later than the first anniversary of the
issuance of such Letter of Credit, which date shall in no event be later than
the Termination Date, and (iv) be subject to the Uniform Customs and, to the
extent not inconsistent therewith, the laws of the Commonwealth of Pennsylvania.
The Issuing Lender shall not at any time be obligated to issue any Letter of
Credit hereunder if such issuance would conflict with, or cause the Issuing
Lender or any L/C Participant to exceed any limits imposed by, any Applicable
Law. References herein to "issue" and derivations thereof with respect to
Letters of Credit shall also include extensions or modifications of any existing
Letters of Credit, unless the context otherwise requires.

         B. Procedure for Issuance of Letters of Credit. JLG, on behalf of the
Borrowers, may from time to time request that the Issuing Lender issue a Letter
of Credit by delivering to the Issuing Lender at the Administrative Agent's
Office an Application therefor, completed to the reasonable satisfaction of the
Issuing Lender, and such other certificates, documents and other papers and
information as the Issuing Lender may reasonably request. Upon receipt of any
Application, the Issuing Lender shall process such Application and the
certificates, documents and other papers and information delivered to it in
connection therewith in accordance with its customary procedures and shall,
subject to Section 3.1 and Article V hereof, promptly issue the Letter of Credit
requested thereby (but in no event shall the Issuing Lender be required to issue
any Letter of Credit earlier than three (3) Business Days after its receipt of
the Application therefor and all such other certificates, documents and other
papers and information relating thereto) by issuing the original of such Letter
of Credit to the beneficiary thereof or as otherwise may be agreed by the
Issuing Lender and the Borrowers. The Issuing Lender shall promptly furnish to
the Borrowers a copy of such Letter of Credit and promptly notify each Lender of
the issuance and, upon request by any Lender, furnish to such Lender a copy of
such Letter of Credit, and the amount of such Lender's participation therein.

         C. Commissions and Other Charges

                  a. The Borrowers shall pay to the Administrative Agent, for
the account of the Issuing Lender and the L/C Participants, a letter of credit
commission with respect to each outstanding Letter of Credit in an amount equal
to the Applicable Margin at the time of issuance of such Letter of Credit on a
per annum basis on the face amount of such Letter of Credit. Such commission
shall be payable quarterly in arrears on the last Business Day of each calendar
quarter and on the Termination Date.

                  b. In addition to the foregoing commission, the Borrowers
shall pay the Issuing Lender an issuance fee of one-eighth of one percent (1/8%)
per annum on the face amount of each Letter of Credit, payable quarterly in
arrears on the last Business Day of each calendar quarter and on the Termination
Date.



                                      -21-
<PAGE>   23

                  c. The Administrative Agent shall, promptly following its
receipt thereof, distribute to the Issuing Lender and the L/C Participants all
commissions received by the Administrative Agent in accordance with their
respective Commitment Percentages.

         D. L/C Participations

                  a. The Issuing Lender irrevocably agrees to grant and hereby
grants to each L/C Participant, and, to induce the Issuing Lender to issue
Letters of Credit hereunder, each L/C Participant irrevocably agrees to accept
and purchase and hereby accepts and purchases from the Issuing Lender, on the
terms and conditions hereinafter stated, for such L/C Participant's own account
and risk an undivided interest equal to such L/C Participant's Commitment
Percentage in the Issuing Lender's obligations and rights under each Letter of
Credit issued hereunder and the amount of each draft paid by the Issuing Lender
thereunder. Each L/C Participant unconditionally and irrevocably agrees with the
Issuing Lender that, if a draft is paid under any Letter of Credit for which the
Issuing Lender is not reimbursed in full by the Borrowers in accordance with the
terms of this Agreement, such L/C Participant shall pay to the Issuing Lender
upon demand at the Issuing Lender's address for notices specified herein an
amount equal to such L/C Participant's Commitment Percentage of the amount of
such draft, or any part thereof, which is not so reimbursed.

                  b. Upon becoming aware of any amount required to be paid by
any L/C Participant to the Issuing Lender pursuant to Section 3.4(a) in respect
of any unreimbursed portion of any payment made by the Issuing Lender under any
Letter of Credit, the Issuing Lender shall notify each L/C Participant of the
amount and due date of such required payment and such L/C Participant shall pay
to the Issuing Lender the amount specified on the applicable due date. If any
such amount is paid to the Issuing Lender after the date such payment is due,
such L/C Participant shall pay to the Issuing Lender on demand, in addition to
such amount, the product of (i) such amount, times (ii) the daily average
Federal Funds Rate as determined by the Administrative Agent during the period
from and including the date such payment is due to the date on which such
payment is immediately available to the Issuing Lender, times (iii) a fraction
the numerator of which is the number of days that elapse during such period and
the denominator of which is 360. A certificate of the Issuing Lender with
respect to any amounts owing under this Section 3.4(b) shall be conclusive in
the absence of manifest error. With respect to payment to the Issuing Lender of
the unreimbursed amounts described in this Section 3.4(b), if the L/C
Participants receive notice that any such payment is due (A) prior to 1:00 p.m.
(Philadelphia time) on any Business Day, such payment shall be due that Business
Day, and (B) after 1:00 p.m. (Philadelphia time) on any Business Day, such
payment shall be due on the following Business Day.

                  c. Whenever, at any time after the Issuing Lender has made
payment under any Letter of Credit and has received from any L/C Participant its
Commitment Percentage of such payment in accordance with this Section 3.4, the
Issuing Lender receives any payment related to such Letter of Credit, whether
directly from the Borrower or otherwise, or any payment of interest on account
thereof, the Issuing Lender will distribute to such L/C Participant its pro rata



                                      -22-
<PAGE>   24

share thereof; provided, that in the event that any such payment received by the
Issuing Lender shall be required to be returned by the Issuing Lender, such L/C
Participant shall return to the Issuing Lender the portion thereof previously
distributed by the Issuing Lender to it.

         E. Reimbursement Obligation of the Borrowers. The Borrowers agree to
reimburse the Issuing Lender on each date on which the Issuing Lender notifies
the Borrowers of the date and amount of a draft paid under any Letter of Credit
for the amount of (a) such draft so paid and (b) any taxes, fees, charges or
other costs or expenses incurred by the Issuing Lender in connection with such
payment. Each such payment shall be made to the Issuing Lender at its address
for notices specified herein in lawful money of the United States and in
immediately available funds. Interest shall be payable on any and all amounts
remaining unpaid by the Borrowers under this Article III from the date such
amounts become payable (whether at stated maturity, by acceleration or
otherwise) until payment in full at the rate which would be payable on any
outstanding Base Rate Loans; provided, however, that if the Borrowers fail to
reimburse the Issuing Lender by the third Business Day following the notice
referred to in this Section 3.5, the Base Rate Loan referred to above shall,
from the initial date due until paid, bear interest at the default rate set
forth in Section 4.1(d) hereof. If the Borrowers fail to timely reimburse the
Issuing Lender on the date the Borrowers receive the notice referred to in this
Section 3.5, the Borrowers shall be deemed to have timely given a Notice of
Borrowing hereunder to the Administrative Agent requesting the Lenders to make a
Base Rate Loan on such date in an amount equal to the amount of such drawing
and, regardless of whether or not the conditions precedent specified in Article
V have been satisfied, the Lenders shall make Base Rate Loans in such amount,
the proceeds of which shall be applied to reimburse the Issuing Lender for the
amount of the related drawing and costs and expenses.

         F. Obligations Absolute. The Borrowers' obligations under this Article
III (including without limitation the Reimbursement Obligation) shall be
absolute and unconditional under any and all circumstances and irrespective of
any set-off, counterclaim or defense to payment which the Borrowers may have or
have had against the Issuing Lender or any beneficiary of a Letter of Credit.
The Borrowers also agree with the Issuing Lender that the Issuing Lender shall
not be responsible for, and the Borrowers' Reimbursement Obligation under
Section 3.5 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even though such
documents shall in fact prove to be invalid, fraudulent or forged, or any
dispute between or among the Borrowers and any beneficiary of any Letter of
Credit or any other party to which such Letter of Credit may be transferred or
any claims whatsoever of the Borrowers against any beneficiary of such Letter of
Credit or any such transferee. The Issuing Lender shall not be liable for any
error, omission, interruption or delay in transmission, dispatch or delivery of
any message or advice, however transmitted, in connection with any Letter of
Credit, except for errors or omissions caused by the Issuing Lender's gross
negligence or willful misconduct. The Borrowers agree that any action taken or
omitted by the Issuing Lender under or in connection with any Letter of Credit
or the related drafts or documents, if done in the absence of gross negligence
or willful misconduct and in accordance with the standards of care specified in
the Uniform Customs and, to the extent not inconsistent therewith, the UCC,
shall be binding on the Borrowers and shall not result



                                      -23-
<PAGE>   25

in any liability of the Issuing Lender to the Borrowers. The responsibility of
the Issuing Lender to the Borrowers in connection with any draft presented for
payment under any Letter of Credit shall, in addition to any payment obligation
expressly provided for in such Letter of Credit, be limited to determining that
the documents (including each draft) delivered under such Letter of Credit in
connection with such presentment are in conformity with such Letter of Credit.

         G. Effect of Application. To the extent that any provision of any
Application related to any Letter of Credit is inconsistent with the provisions
of this Article III, the provisions of this Article III shall apply.

IV.                          GENERAL LOAN PROVISIONS

         A. Interest

                  a. Interest Rate Options. Subject to the provisions of this
Section 4.1, at the election of the Borrowers, the aggregate principal balance
of (i) the Revolving Credit Notes or any portion thereof shall bear interest at
(A) the Base Rate or (B) the LIBOR Rate plus the Applicable Margin as set forth
in Section 4.1(c); provided that the LIBOR Rate shall not be available until
three (3) Business Days after the Closing Date and (ii) any Swingline Loan shall
bear interest at the Base Rate. JLG shall select the rate of interest and
Interest Period, if any, applicable to any Loan at the time a Notice of
Borrowing is given pursuant to Section 2.3 or at the time a Notice of
Conversion/Continuation is given pursuant to Section 4.2. Each Loan or portion
thereof bearing interest based on the Base Rate shall be a Base Rate Loan, and
each Loan or portion thereof bearing interest based on the LIBOR Rate shall be a
LIBOR Rate Loan. Any Loan or any portion thereof as to which JLG has not duly
specified an interest rate as provided herein shall be deemed a Base Rate Loan.

                  b. Interest Periods. In connection with each LIBOR Rate Loan,
JLG, by giving notice as described in Section 4.1(a), shall elect an interest
period (each, an "Interest Period") to be applicable to such Loan, which
Interest Period shall be a period of one (1), two (2), three (3), or six (6)
months with respect to each LIBOR Rate Loan; provided that:

                           (1) the Interest Period shall commence on the date of
advance of or conversion to any LIBOR Rate Loan and, in the case of immediately
successive Interest Periods, each successive Interest Period shall commence on
the date on which the next preceding Interest Period expires;

                           (2) if any Interest Period would otherwise expire on
a day that is not a Business Day, such Interest Period shall expire on the next
succeeding Business Day; provided, that if any Interest Period with respect to a
LIBOR Rate 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 Interest Period shall expire on the next preceding Business Day;



                                      -24-

                           (3) any Interest Period with respect to a LIBOR Rate
Loan that begins on the last Business Day of a calendar month (or on a day for
which there is no numerically corresponding day in the calendar month at the end
of such Interest Period) shall end on the last Business Day of the relevant
calendar month at the end of such Interest Period;

                           (4) no Interest Period shall extend beyond the
Termination Date; and

                           (5) there shall be no more than six (6) LIBOR Rate
Loans outstanding at any time.

                  c. Applicable Margin. The Applicable Margin provided for in
Section 4.1(a) with respect to the Loans (the "Applicable Margin") shall (i) on
the Closing Date through the last day of the second full fiscal quarter after
the Closing Date be equal to the Applicable Margin set forth in Level III below,
and (ii) for each fiscal quarter thereafter, be determined by reference to the
Leverage Ratio as of the end of the fiscal quarter immediately preceding the
delivery of the applicable Officer's Compliance Certificate as follows:

<TABLE>
<CAPTION>
      Level             Leverage Ratio       Applicable Margin
      -----             --------------       -----------------

<S>                     <C>                  <C>
        I                    > = 2.5               112.5 bps

        II            > = 2.0 and < 2.5            100.0 bps

       III            > = 1.5 and < 2.0             87.5 bps

        IV            > = 1.0 and < 1.5             70.0 bps

        V                    < 1.0                  55.0 bps
</TABLE>

Adjustments, if any, in the Applicable Margin shall be made by the
Administrative Agent on the third (3rd) Business Day after receipt by the
Administrative Agent of quarterly financial statements for JLG and its
Subsidiaries and the accompanying Officer's Compliance Certificate setting forth
the Leverage Ratio of the Borrowers and their Subsidiaries as of the most recent
fiscal quarter end. Subject to Section 4.1(d), in the event the Borrowers fail
to deliver such financial statements and certificate within the time required by
Section 7.2(c) hereof, the Applicable Margin may, at the discretion of the
Administrative Agent, be the highest Applicable Margin set forth above until the
delivery of such financial statements and certificate.

                  d. Default Rate. Subject to Section 11.3, at the discretion of
the Administrative Agent and Required Lenders, upon the occurrence and during
the continuance of an Event of Default, (i) the Borrowers shall no longer have
the option to request LIBOR Rate Loans,



                                      -25-
<PAGE>   27

(ii) all outstanding LIBOR Rate Loans shall bear interest at a rate per annum
two percent (2%) in excess of the rate then applicable to LIBOR Rate Loans, as
applicable, until the end of the applicable Interest Period, and thereafter at a
rate equal to two percent (2%) in excess of the rate then applicable to Base
Rate Loans, and (iii) all outstanding Base Rate Loans shall bear interest at a
rate per annum equal to two percent (2%) in excess of the rate then applicable
to Base Rate Loans. Interest shall continue to accrue on the Notes after the
filing by or against the Borrowers of any petition seeking any relief in
bankruptcy or under any act or law pertaining to insolvency or debtor relief,
whether state, federal or foreign.

                  e. Interest Payment and Computation. Interest on each Base
Rate Loan shall be payable in arrears on the last Business Day of each calendar
quarter commencing June 30, 1999; and interest on each LIBOR Rate Loan shall be
payable on the last day of each Interest Period applicable thereto, and if such
Interest Period extends over three (3) months, at the end of each three (3)
month interval during such Interest Period. Interest on LIBOR Rate Loans and all
fees payable hereunder shall be computed on the basis of a 360-day year and
assessed for the actual number of days elapsed and interest on Base Rate Loans
shall be computed on the basis of a 365/66-day year and assessed for the actual
number of days elapsed.

         B. Notice and Manner of Conversion or Continuation of Loans. Provided
that no Event of Default has occurred and is then continuing, the Borrowers
shall have the option to (a) convert at any time following the third Business
Day after the Closing Date all or any portion of its outstanding Base Rate Loans
(other than Swingline Loans) in a principal amount equal to $1,000,000 or any
whole multiple of $1,000,000 in excess thereof into one or more LIBOR Rate Loans
and (b) upon the expiration of any Interest Period, (i) convert all or any part
of its outstanding LIBOR Rate Loans in a principal amount equal to $3,000,000 or
a whole multiple of $1,000,000 in excess thereof into Base Rate Loans or (ii)
continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the Borrower
desires to convert or continue Loans as provided above, the Borrower shall give
the Administrative Agent irrevocable prior written notice in the form attached
as Exhibit E (a Notice of Conversion/Continuation ) not later than 11:00 a.m.
(Philadelphia time) three (3) Business Days before the day on which a proposed
conversion or continuation of such Loan is to be effective specifying (A) the
Loans to be converted or continued, and, in the case of any LIBOR Rate Loan to
be converted or continued, the last day of the Interest Period therefor, (B) the
effective date of such conversion or continuation (which shall be a Business
Day), (C) the principal amount of such Loans to be converted or continued, and
(D) the Interest Period to be applicable to such converted or continued LIBOR
Rate Loan. The Administrative Agent shall promptly notify the Lenders of such
Notice of Conversion/Continuation.

         C. Fees.

                  a. Facility Fees. The Borrowers shall pay to the
Administrative Agent, for the account of the Lenders, quarterly in arrears,
regardless of usage, a non-refundable facility fee



                                      -26-
<PAGE>   28

at a rate per annum to be determined by reference to the Leverage Ratio as
follows times the then current Aggregate Commitment:

        V                   < 1.0                    20.0 bps
</TABLE>

; provided, however, that the applicable annual facility fee from the Closing
Date through the last day of the second full fiscal quarter of JLG after the
Closing Date shall be equal to the annual facility fee set forth in Level III
above. Adjustments, if any, in the applicable facility fee shall be made by the
Administrative Agent on the third (3rd) Business Day after receipt by the
Administrative Agent of quarterly financial statements for JLG and its
Subsidiaries and the accompanying Officer's Compliance Certificate setting forth
the Leverage Ratio of the Borrowers and their Subsidiaries as of the most recent
fiscal quarter end. In the event the Borrowers fail to deliver such financial
statements and certificate within the time required by Section 7.2(c) hereof,
the applicable facility fee may, at the discretion of the Administrative Agent,
the highest facility fee set forth above until the delivery of such financial
statements and certificates.

                  b. Administrative Agent's and Other Fees. In order to
compensate the Administrative Agent for structuring and syndicating the Loans
and for its obligations hereunder, the Borrowers agree to pay to the
Administrative Agent, for its account, the fees set forth in the separate fee
letter agreement executed by JLG and the Administrative Agent dated May 5, 1999.

         D. 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
(including the Reimbursement Obligation) 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 11.1, 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



                                      -27-
<PAGE>   29

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 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
Issuing Lender's fees, Lenders' facility fee or L/C Participants' commissions
shall be made in like manner, but for the account of the Issuing Lender or the
L/C Participants, as the case may be. 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 4.8,
4.9, 4.10, 4.11 or 13.2 shall be paid to the Administrative Agent for the
account of the applicable Lender. Subject to Section 4.1(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.

         E. 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 11.2, 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 and Issuing
Lender'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
Swingline Note to the Swingline Lender, then to the principal amount outstanding
under the Swingline Note to the Swingline Lender, then to accrued and unpaid
interest on the Revolving Credit Notes, the Reimbursement Obligation 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 Revolving Credit Notes and Reimbursement Obligation (pro
rata in accordance with all such amounts due) and then to the cash collateral
account described in Section 11.2(b) hereof to the extent of any L/C Obligations
then outstanding, in that order.

         F. 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
Extensions of Credit, 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



                                      -28-
<PAGE>   30

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 Extensions of Credit 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.

         G. Nature of Obligations of Lenders Regarding Extensions of Credit;
Assumption by the Administrative Agent. The obligations of the Lenders under
this Agreement to make the Loans and issue or participate in Letters of Credit
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
2.3(b), 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.

         H. 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



                                      -29-
<PAGE>   31

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 Loans 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:

                           (1) 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, Letter of Credit or Application 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, Letter of Credit or
Application 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



                                      -30-
<PAGE>   32

                           (2) 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 issuing or participating in
Letters of Credit 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 or Letter of Credit or Application, 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 4.8(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.

         I. 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 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.



                                      -31-
<PAGE>   33

         J. 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.

         K. Taxes.

                  a. Payments Free and Clear. Subject to compliance by Lenders
with Section 4.11(e), any and all payments by the Borrowers hereunder or under
the Notes or the Letters of Credit 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 or Letter of Credit 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 4.11) 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 4.11(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



                                      -32-
<PAGE>   34

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 Letters of
Credit, 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 4.11) 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.

                  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 13.1, 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

representations and warranties) both before and after giving effect to the
transactions contemplated hereunder (including the Merger) 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 and to carry on its business as now being and

business in each jurisdiction in which the character of its properties or the
nature





                                      -38-
<PAGE>   40

of its business requires such qualification and authorization, except where any
failure to be so qualified would not have a Material Adverse Effect. The

qualified to do business as of the Closing Date are described on Schedule
6.1(a).

                  b. Ownership; Investments. Each Subsidiary of any Borrower as

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

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

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

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.

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 6.1(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 6.1(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 true and complete copy of each Material Contract required to be listed
on Schedule 6.1(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 6.1(m). Except as set forth in Schedule 6.1(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



                                      -43-
<PAGE>   45

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 (A) the Consolidated
balance sheet of JLG and its Subsidiaries as of July 31, 1998 and the related
statements of income and retained earnings and cash flows for the Fiscal Years
then ended (the "Audited JLG Financial Statements") and (B) the unaudited
Consolidated balance sheet of JLG and its Subsidiaries as of April 30, 1999 and
related unaudited interim statements of revenue and retained earnings 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.

                           (1) Copies of (A) the Consolidated balance sheet of
Gradall and its Subsidiaries as of December 31, 1998 and the related statements
of income and retained earnings and cash flows for the Fiscal Years then ended
(the "Audited Gradall Financial Statements") and (B) the unaudited Consolidated
balance sheet of Gradall and its Subsidiaries as of March 31, 1999 and related
unaudited interim statements of revenue and retained earnings have been
furnished to the Administrative Agent and each Lender. The Audited Gradall
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 Gradall and its
Subsidiaries as at such dates and the results of operations and changes of
financial position for the periods then ended. Neither Gradall 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, 1998 , 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; and (ii) since December 31, 1998 there has been no
material adverse change in the properties, business, operations, prospect or
condition (financial or otherwise) of Gradall or its Subsidiaries, on a
Consolidated basis, and which, in either case, 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



                                      -44-
<PAGE>   46

limitation, contingent liabilities, (ii) the present fair salable value of 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 6.1(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 10.3. 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
10.3 hereof.



                                      -45-
<PAGE>   47

                  t. Debt and Guaranty Obligations. Except for such Debt and
Guaranty Obligations otherwise permitted pursuant to this Agreement, Schedule
6.1(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 6.1(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.

                  x. Year 2000 Compliance. Borrowers and Subsidiaries have
commenced to conduct a review and assessment of their material computer systems
and applications, micro-



                                      -46-
<PAGE>   48

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 and Gradall 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 and Gradall 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 know of no claim for any fees or commissions, in
connection with Borrowers' obtaining the Commitment or the Loans from Lenders,
except those provided herein.

                  z. Share Purchase; Merger Agreement.

                           (1) Validity. Each Borrower, Gradall and JLG
Acquisition Corp. has the power and authority under the laws of its state of
incorporation and under its articles of incorporation and by-laws to enter into
and perform the Share Purchase and Merger Agreement (to which each is a party,
respectively) and all other agreements, documents and actions required
thereunder; and all actions (corporate or otherwise) necessary or appropriate
for the execution and performance by each Borrower, Gradall and JLG Acquisition
Corp. of the Share Purchase and the Merger Agreement (to which each is a party,
respectively) and all other documents, agreements and actions required
thereunder have been taken.

                           (2) No Violations. The making and performance of the
Share Purchase, the Merger Agreement and all other agreements, documents and
actions required thereunder, will not violate any provision of any law or
regulation, federal, state or local, including without limitation all state
corporate laws and judicial precedents of the states of incorporation of each
Borrower, Gradall and JLG Acquisition Corp. and will not violate any provisions
of the articles of incorporation and by-laws of any Borrower, Gradall or JLG
Acquisition Corp., or constitute a default under any agreement by which any
Borrower, Gradall or JLG Acquisition Corp. or its respective property may be
bound.

                  aa. 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).

                  ab. 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



                                      -47-
<PAGE>   49

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.

         B. Survival of Representations and Warranties, Etc. All representations
and warranties set forth in this Article VI 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.

VII.                    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 13.11 hereof, the Borrowers will furnish or cause to be furnished to

VIII.                         AFFIRMATIVE COVENANTS

         Until all of the Obligations have been paid and satisfied in full and
the Commitments terminated, unless consent has been obtained in the manner
provided for in Section 13.11, each Borrower will, and will cause each
Subsidiary to:

         A. Preservation of Corporate Existence and Related Matters. Except as
permitted by Section 10.5, preserve and maintain its separate legal existence
and all rights, franchises, licenses and privileges necessary to the conduct of
its business, and qualify and remain qualified as a foreign corporation or other
entity and authorized to do business in each jurisdiction in which the failure
to so qualify would have a Material Adverse Effect.

         B. Maintenance of Property. Except for dispositions permitted by
Section 10.6(b) or disuse in the ordinary course of business, protect and
preserve all properties useful in and material to its business, including all
material copyrights, patents, trade names and trademarks and other intellectual
property; maintain in good working order and condition all material buildings,
equipment and other tangible real and personal property; and from time to time
make or cause to be made all renewals, replacements and additions to such
material property necessary for the conduct of its business, so that the
business carried on in connection therewith may be properly and advantageously
conducted at all times.

         C. Insurance. Maintain insurance with financially sound and reputable
insurance companies, against such risks and in such amounts as are customarily
maintained by similar businesses and as may be required by Applicable Law, and
on the Closing Date and from time to time thereafter deliver to the
Administrative Agent upon its request a detailed list of the insurance then in
effect, stating the names of the insurance companies, the amounts and rates of
the insurance, the dates of the expiration thereof and the properties and risks
covered thereby.



                                      -51-
<PAGE>   53

         D. Accounting Methods and Financial Records. Maintain a system of
accounting, and keep such books, records and accounts (which shall be true and
complete in all material respects) as may be required or as may be necessary to
permit the preparation of financial statements in accordance with GAAP and in
compliance with the regulations of any Governmental Authority having
jurisdiction over it or any of its properties.

         E. Payment and Performance of Obligations. Pay and perform all
Obligations under this Agreement and the other Loan Documents, and pay or
perform (a) all taxes, assessments and other governmental charges that may be
levied or assessed upon it or any of its property, and (b) all other
indebtedness, obligations and liabilities in accordance with customary trade
practices; provided, that a Borrower or Subsidiary may contest any item
described in clauses (a) or (b) of this Section 8.5 in good faith so long as
adequate reserves are maintained with respect thereto in accordance with GAAP.

         F. Compliance With Laws and Approvals. Observe and remain in compliance
with all Applicable Laws and maintain in full force and effect all Governmental
Approvals, in each case applicable to the conduct of its business, except where
failure to comply or maintain would not reasonably be expected to have a
Material Adverse Effect.

         G. Environmental Laws. In addition to and without limiting the
generality of Section 8.6, (a) comply with, and ensure such compliance by all
tenants and subtenants with all applicable Environmental Laws and obtain and
comply with and maintain, and ensure that all tenants and subtenants obtain and
comply with and maintain, any and all licenses, approvals, notifications,
registrations or permits required by applicable Environmental Laws, (b) conduct
and complete all investigations, studies, sampling and testing, and all
remedial, removal and other actions required under Environmental Laws, and
promptly comply with all lawful orders and directives of any Governmental
Authority regarding Environmental Laws except in the case of any of the
foregoing where such non-compliance would not reasonably be expected to have a
Material Adverse Effect, and (c) defend, indemnify and hold harmless the
Administrative Agent and the Lenders, and their respective parents,
Subsidiaries, Affiliates, employees, agents, officers and directors, from and
against any claims, demands, penalties, fines, liabilities, settlements,
damages, costs and expenses of whatever kind or nature known or unknown,
contingent or otherwise, arising out of, or in any way relating to the presence
of Hazardous Materials, or the violation of, noncompliance with or liability
under any Environmental Laws applicable to the operations of any Borrower or
Subsidiary, or any orders, requirements or demands of Governmental Authorities
related thereto, including, without limitation, reasonable attorney's and
consultant's fees, investigation and laboratory fees, response costs, court
costs and litigation expenses, except to the extent that any of the foregoing
directly result from the gross negligence or willful misconduct of the party
seeking indemnification therefor.

         H. Compliance with ERISA. In addition to and without limiting the
generality of Section 8.6, (a) comply in all material respects with all
applicable provisions of ERISA and the



                                      -52-
<PAGE>   54

regulations and published interpretations thereunder with respect to all

         B. Remedies. Upon the occurrence of an Event of Default, with the
consent of the Required Lenders, the Administrative Agent may, or upon the
request of the Required Lenders, the Administrative Agent shall, by notice to

                  a. Acceleration; Termination of Facilities. Declare the
principal of and interest on the Loans, the Notes and the Reimbursement
Obligations at the time outstanding, and all other amounts owed to the Lenders
and to the Administrative Agent under this Agreement or any of the other Loan
Documents (including, without limitation, all L/C Obligations, whether or not
the beneficiaries of the then outstanding Letters of Credit shall have presented
the documents required thereunder) and all other Obligations (other than
obligations owing under any Hedging Agreement), to be forthwith due and payable,
whereupon the same shall immediately become due and payable without presentment,
demand, protest or other notice of any kind, all of which are expressly waived,
anything in this Agreement or the other Loan Documents to the contrary
notwithstanding, and



                                      -64-
<PAGE>   66

terminate the Credit Facility and any right of the Borrowers to request
borrowings or Letters of Credit thereunder; provided, that upon the occurrence
of an Event of Default specified in Section 11.1(j) or (k), the Credit Facility
shall be automatically terminated and all Obligations (other than obligations
owing under any Hedging Agreement) shall automatically become due and payable.

                  b. Letters of Credit. With respect to all Letters of Credit
with respect to which presentment for honor shall not have occurred at the time
of an acceleration pursuant to the preceding paragraph, require the Borrowers at
such time to deposit in a cash collateral account opened by the Administrative
Agent an amount equal to the aggregate then undrawn and unexpired amount of such
Letters of Credit. Amounts held in such cash collateral account shall be applied
by the Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay the
other Obligations. After all such Letters of Credit shall have expired or been
fully drawn upon, the Reimbursement Obligation shall have been satisfied and all
other Obligations shall have been paid in full, the balance, if any, in such
cash collateral account shall be returned to the Borrowers.

                  c. Rights of Collection. Exercise on behalf of the Lenders all
of its other rights and remedies under this Agreement, the other Loan Documents
and Applicable Law, in order to satisfy all of the Borrowers' Obligations.

         C. Rights and Remedies Cumulative; Non-Waiver, etc. The enumeration of
the rights and remedies of the Administrative Agent and the Lenders set forth in
this Agreement is not intended to be exhaustive and the exercise by the
Administrative Agent and the Lenders of any right or remedy shall not preclude
the exercise of any other rights or remedies, all of which shall be cumulative,
and shall be in addition to any other right or remedy given hereunder or under
the Loan Documents or that may now or hereafter exist in law or in equity or by
suit or otherwise. No delay or failure to take action on the part of the
Administrative Agent or any Lender in exercising any right, power or privilege
shall operate as a waiver thereof, nor shall any single or partial exercise of
any such right, power or privilege preclude other or further exercise thereof or
the exercise of any other right, power or privilege or shall be construed to be
a waiver of any Event of Default. No course of dealing between the Borrowers,
the Administrative Agent and the Lenders or their respective agents or employees
shall be effective to change, modify or discharge any provision of this
Agreement or any of the other Loan Documents or to constitute a waiver of any
Event of Default.

XII.                        THE ADMINISTRATIVE AGENT

         A. Appointment. Each of the Lenders hereby irrevocably designates and
appoints First Union as Administrative Agent of such Lender under this Agreement
and the other Loan Documents for the term hereof, and each such Lender
irrevocably authorizes First Union, as Administrative Agent for such Lender, to
take such action on its behalf under the provisions of this Agreement and



                                      -65-
<PAGE>   67

the other Loan Documents and to exercise such powers and perform such duties as
are expressly delegated to the Administrative Agent by the terms of this
Agreement and such other Loan Documents, together with such other powers as are
reasonably incidental thereto. Notwithstanding any provision to the contrary
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
Administrative Agent in this Article XII shall be deemed to refer to the
Administrative Agent solely in its capacity as Administrative Agent and not in
its capacity as a Lender.

         B. Delegation of Duties. The Administrative Agent may 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 advice of counsel
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or
attorneys-in-fact (other than the Administrative Agent's employees) selected by
the Administrative Agent with reasonable care.

         C. Exculpatory Provisions. Neither the Administrative Agent nor any of
its officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or
Affiliates shall be (a) liable for any action lawfully taken or omitted to be
taken by it or such Person under or in connection with this Agreement or the
other Loan Documents (except for actions occasioned solely by its or such
Person's own gross negligence or willful misconduct), or (b) 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 inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Agreement, or to inspect the properties, books or records of the
Borrowers or any of their Subsidiaries.

         D. Reliance by the Administrative Agent. The Administrative Agent shall
be entitled to rely, and shall be fully protected in relying, upon 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



                                      -66-
<PAGE>   68

accordance with Section 13.10 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.

         E. 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.

         F. 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 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



                                      -67-
<PAGE>   69

Subsidiaries and made its own decision to make its Loans and issue or
participate in Letters of Credit hereunder 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.

         G. 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 or any Reimbursement Obligation) 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 12.7 shall survive the payment of the Notes, any Reimbursement
Obligation and all other amounts payable hereunder and the termination of this
Agreement.

         H. 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 were not an Administrative
Agent hereunder. With respect to any Loans made or renewed by it and any Note
issued to it and with respect to any Letter of Credit issued by it or
participated in by 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.

         I. 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



                                      -68-
<PAGE>   70

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 12.9 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.

XIII.                             MISCELLANEOUS

         A. Notices.

                  a. Method of Communication. Except as otherwise provided in
this Agreement, all notices and communications hereunder shall be in writing, or

delivered by hand delivery or sent via telecopy, recognized overnight courier
service or certified mail, return receipt requested, and shall be presumed to be

sent by telecopy, (ii) on the next Business Day if sent by recognized overnight
courier service and (iii) on the third Business Day following the date sent by
certified mail, return receipt requested. A telephonic notice to the

without notice to the Borrowers or to any other Person, any such notice being
hereby expressly waived, to set off and to appropriate and to apply any and all
deposits (general or special, time or demand, including, but not limited to,
indebtedness evidenced by certificates of deposit, whether matured or unmatured)
and any other indebtedness at any time held or owing by the Lenders, or any such
assignee or participant to or for the credit or the account of any Borrower
against and on account of the Obligations irrespective of whether or not (a) the
Lenders shall have made any demand under this Agreement or any of the other Loan

         E. Consent to Jurisdiction. The Borrowers hereby irrevocably consent to
the personal jurisdiction of the state and federal courts located in
Philadelphia County, Pennsylvania, in any action, claim or other proceeding
arising out of any dispute in connection with this Agreement, the Notes and the
other Loan Documents, any rights or obligations hereunder or thereunder, or 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

Administrative Agent or any Lender to serve legal process in any other manner
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.

         F. 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 or under applicable law or by judicial foreclosure and sale,
(ii) all rights of self help including peaceful occupation of property and
collection of rents, set off, and peaceful possession of property, (iii)
obtaining provisional or ancillary remedies including injunctive relief,
sequestration, garnishment, attachment, appointment of receiver and in filing an
involuntary bankruptcy proceeding, and (iv) when applicable, a judgment by
confession of judgment.

         G. 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,



                                      -72-
<PAGE>   74

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.

         H. 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.

         I. 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.

         J. Successors and Assigns; Participations.

                  a. Benefit of Agreement. This Agreement shall be binding upon
and inure to the benefit of the Borrowers, the Administrative Agent and the
Lenders, all future holders of the Notes, and their respective successors and
assigns, except that the Borrowers shall not assign or transfer any of their
rights or obligations under this Agreement without the prior written consent of
each Lender.

                  b. Assignment by Lenders. Each Lender may, with the consent of
the Borrowers (so long as no Default or Event of Default has occurred and is
continuing) and the consent of the Administrative Agent, which consents shall
not be unreasonably withheld, assign to one or more Eligible Assignees all or a
portion of its interests, rights and obligations under this Agreement
(including, without limitation, all or a portion of the Extensions of Credit at
the time owing to it and the Notes held by it); provided that:



                                      -73-

                           (1) each such assignment shall be of a constant, and
not a varying, percentage of all the assigning Lender s rights and obligations
under this Agreement;

                           (2) if less than all of the assigning Lender's
Commitment is to be assigned, the Commitment so assigned shall not be less than
$5,000,000.

                           (3) the parties to each such assignment shall execute
and deliver to the Administrative Agent, for its acceptance and recording in the
Register, an Assignment and Acceptance in the form of Exhibit H attached hereto
(an Assignment and Acceptance ), together with any Note or Notes subject to such
assignment;

                           (4) such assignment shall not, without the consent of
the Borrowers, require the Borrowers to file a registration statement with the
Securities and Exchange Commission or apply to or qualify the Loans or the Notes
under the blue sky laws of any state; and

                           (5) the assigning Lender shall pay to the
Administrative Agent an assignment fee of $3,000 upon the execution by such
Lender of the Assignment and Acceptance; provided that no such fee shall be
payable (i) upon any assignment by a Lender to an Affiliate thereof and (ii)
with respect to any assignment made prior to June 24, 1999.

Upon such execution, delivery, acceptance and recording, from and after the
effective date specified in each Assignment and Acceptance, which effective date

assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereby

be released from its obligations under this Agreement.

                  c. Rights and Duties Upon Assignment. By executing and
delivering an Assignment and Acceptance, the assigning Lender thereunder and the
assignee thereunder confirm to and agree with each other and the other parties
hereto as set forth in such Assignment and Acceptance.

each Assignment and Acceptance delivered to it and a register for the
recordation of the names and addresses of the Lenders and the amount of the
Extensions of Credit with respect to each Lender from time to time (the Register
). The entries in the Register shall be conclusive, in the absence of manifest
error, and the Borrowers, the Administrative Agent and the Lenders may treat
each person whose name is recorded in the Register as a Lender hereunder for all
purposes of this Agreement. The Register shall be available for inspection by
the Borrowers or Lenders at any reasonable time and from time to time upon
reasonable prior notice.

amount equal to the Commitment retained by it hereunder. Such new Note or Notes
shall be in an aggregate principal amount equal to the aggregate principal
amount of such surrendered Note or Notes, shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be in substantially the form
of the assigned Notes delivered to the assigning Lender. Each surrendered Note
or Notes shall be canceled and returned to the Borrowers.

Extensions of Credit and the Notes held by it); provided that:

                  a. each such participation shall be in an amount not less than
$5,000,000;

                  b. such Lender's obligations under this Agreement (including,

<PAGE>   77

                  e. the Borrowers, the Administrative Agent and the other

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

of the Obligations remain unpaid or unsatisfied or the Credit Facility has not
been terminated.

this Agreement are for convenience only, and neither limit nor amplify the
provisions of this Agreement.

transaction or act, the Borrowers shall or would be in breach of any other
