practice is required by the Financial Accounting Standards Board (or any such
successor) in order for such principle or practice to continue as a generally

excess of the Highest Lawful Rate applicable to such Lender.

ARTICLE II - Loans

         Section 2.1.  Commitments to Lend; Notes.  Subject to the terms and
conditions hereof, each Lender agrees to make loans to Borrower (herein called
such Lender's "Loans") upon Borrower's request from time to time during the
Commitment Period, provided that (a) only one advance of new funds may be
borrowed hereunder, and all Loans thereafter must be continuations or
conversions of previous Loans, (b) the aggregate amount requested from all
Lenders for such advance of new funds may not exceed the Maximum Loan Amount,
and (c) subject to Sections 3.3, 3.4 and 3.6, all Lenders must be requested to
make Loans of the same Type in accordance with their respective Percentage
Shares and as part of the same Borrowing.  The aggregate amount of all
Eurodollar Loans in any Borrowing must be greater than or equal to $3,000,000,
and the aggregate amount of all Base Rate Loans in any Borrowing must be
greater than or equal to $1,000,000.  Borrower may have no more than six
Borrowings of Eurodollar Loans outstanding at any time.  The obligation of
Borrower to repay to each Lender the aggregate amount of all Loans made by such
Lender, together with interest accruing in connection therewith, shall be
evidenced by a single promissory note (herein called such Lender's "Note") made
by Borrower payable to the order of such Lender in the form of Exhibit A with
appropriate insertions.  The amount of principal owing on any Lender's Note at
any given time shall be the aggregate amount of all funds lent by such Lender
under such Note minus all payments of principal theretofore received by such
Lender on such Note.  Interest on each Note shall accrue and be due and payable
as provided herein and therein, with Eurodollar Loans bearing interest at the
Eurodollar Rate and Base Rate Loans bearing interest at the Base Rate (subject
to the applicability of the Default Rate and limited by the provisions of
Section 10.7).  Funds borrowed and repaid hereunder may not be reborrowed.

         Section 2.2.  Requests for New Loans.  Borrower must give to Agent
written notice of its requested Borrowing of the single advance of new funds to
be lent hereunder by Lenders.  Such notice constitutes a "Borrowing Notice"
hereunder and must:





                                       13
<PAGE>   18
                 (a)  specify (i) the aggregate amount of any such Borrowing of
         new Base Rate Loans and the date on which such Base Rate Loans are to
         be advanced, or (ii) the aggregate amount of any such Borrowing of new
         Eurodollar Loans, the date on which such Eurodollar Loans are to be
         advanced (which shall be the first day of the Interest Period which is
         to apply thereto), and the length of the applicable Interest Period;
         and

                 (b)  be received by Agent not later than 10:00 a.m., New York,
         New York time, on (i) the day on which any such Base Rate Loans are to
         be made, or (ii) the third Business Day preceding the day on which any
         such Eurodollar Loans are to be made.

Such request must be made in the form and substance of the "Borrowing Notice"
attached hereto as Exhibit B-1, duly completed.  Upon receipt of any such
Borrowing Notice, Agent shall give each Lender prompt notice of the terms
thereof.  If all conditions precedent to such new Loans have been met, each
Lender will on the date requested promptly remit to Agent at Agent's office in
New York, New York the amount of such Lender's new Loan in immediately
available funds, and upon receipt of such funds, unless to its actual knowledge
any conditions precedent to such Loans have been neither met nor waived as
provided herein, Agent shall promptly make such Loans available to Borrower.
Unless Agent shall have received prompt notice from a Lender that such Lender
will not make available to Agent such Lender's new Loan, Agent may in its
discretion assume that such Lender has made such Loan available to Agent in
accordance with this section and Agent may if it chooses, in reliance upon such
assumption, make such Loan available to Borrower.  If and to the extent such
Lender shall not so make its new Loan available to Agent, such Lender and
Borrower severally agree to pay or repay to Agent within three days after
demand the amount of such Loan together with interest thereon, for each day
from the date such amount was made available to Borrower until the date such
amount is paid or repaid to Agent, with interest at (i) the Federal Funds Rate,
if such Lender is making such payment and (ii) the interest rate applicable at
the time to the other new Loans made on such date, if Borrower is making such
repayment.  If neither such Lender nor Borrower pay or repay to Agent such
amount within such three-day period, Agent shall in addition to such amount be
entitled to recover from such Lender and from Borrower, on demand, interest
thereon at the Default Rate, calculated from the date such amount was made
available to Borrower.  The failure of any Lender to make any new Loan to be
made by it hereunder shall not relieve any other Lender of its obligation
hereunder, if any, to make its new Loan, but no Lender shall be responsible for
the failure of any other Lender to make any new Loan to be made by such other
Lender.

         Section 2.3.  Continuations and Conversions of Existing Loans.
Borrower may make the following elections with respect to Loans already
outstanding: to convert Base Rate Loans to Eurodollar Loans, to convert
Eurodollar Loans to Base Rate Loans on the last day of the Interest Period
applicable thereto, or to continue Eurodollar Loans beyond the expiration of
such Interest Period by designating a new Interest Period to take effect at the
time of such expiration.  In making such elections, Borrower may combine
existing Loans made pursuant to separate Borrowings into one new Borrowing or
divide existing Loans made pursuant to one Borrowing into separate new
Borrowings.  To make any such election, Borrower must give to Agent written
notice (or telephonic notice promptly confirmed in writing) of any such
conversion or continuation of existing Loans, with a separate notice given for
each new Borrowing.  Each such notice constitutes a "Continuation/Conversion
Notice" hereunder and must:





                                       14
<PAGE>   19
                 (a)  specify the existing Loans which are to be continued or
         converted;

                 (b)  specify (i) the aggregate amount of any Borrowing of Base
         Rate Loans into which such existing Loans are to be continued or
         converted and the date on which such continuation or conversion is to
         occur, or (ii) the aggregate amount of any Borrowing of Eurodollar
         Loans into which such existing Loans are to be continued or converted,
         the date on which such continuation or conversion is to occur (which
         shall be the first day of the Interest Period which is to apply to
         such Eurodollar Loans), and the length of the applicable Interest
         Period; and

                 (c)  be received by Agent not later than 10:00 a.m., New York,
         New York time, on (i) the day on which any such continuation or
         conversion to Base Rate Loans is to occur, or (ii) the third Business
         Day preceding the day on which any such continuation or conversion to
         Eurodollar Loans is to occur.

Each such written request or confirmation must be made in the form and
substance of the "Continuation/Conversion Notice" attached hereto as Exhibit
B-2, duly completed.  Each such telephonic request shall be deemed a
representation, warranty, acknowledgment and agreement by Borrower as to the
matters which are required to be set out in such written confirmation.  Upon
receipt of any such Borrowing Notice, Agent shall give each Lender prompt
notice of the terms thereof.  Each Borrowing Notice shall be irrevocable and
binding on Borrower.  During the continuance of any Default, Borrower may not
make any election to convert existing Loans into Eurodollar Loans or continue
existing Loans as Eurodollar Loans.  If (due to the existence of a Default or
for any other reason) Borrower fails to timely and properly give any notice of
continuation or conversion with respect to a Borrowing of existing Eurodollar
Loans at least three days prior to the end of the Interest Period applicable
thereto, such Eurodollar Loans shall automatically be converted into Base Rate
Loans at the end of such Interest Period.  No new funds shall be repaid by
Borrower or advanced by any Lender in connection with any continuation or
conversion of existing Loans pursuant to this section, and no such continuation
or conversion shall be deemed to be a new advance of funds for any purpose;
such continuations and conversions merely constitute a change in the interest
rate applicable to already outstanding Loans.

         Section 2.4.  Use of Proceeds.  Borrower shall use all Loans to
finance capital expenditures and provide working capital for its operations and
for other general business purposes.  In no event shall the funds from any Loan
be used directly or indirectly by any Person for personal, family, household or
agricultural purposes or for the purpose, whether immediate, incidental or
ultimate, of purchasing, acquiring or carrying any "margin stock" or any
"margin securities" (as such terms are defined respectively in Regulation U and
Regulation G promulgated by the Board of Governors of the Federal Reserve
System) or to extend credit to others directly or indirectly for the purpose of
purchasing or carrying any such margin stock or margin securities.  Borrower
represents and warrants that Borrower is not engaged principally, or as one of
Borrower's important activities, in the business of extending credit to others
for the purpose of purchasing or carrying such margin stock or margin
securities.

         Section 2.5.  Agent's Fees.  In addition to all other amounts due to
Agent under the Loan Documents, Borrower will pay fees to Agent as described in
a letter agreement dated of even date herewith between Agent and Borrower.

         Section 2.6.  Prepayments.

         (a)  Borrower may at its option, upon one Business Day's advance
notice to each Lender, from time to time and without premium or penalty prepay
the Notes, in whole or in part, so long as the aggregate amounts of all partial
prepayments of principal on the Notes equals or exceeds $1,000,000 and so long
as Borrower does not prepay any Eurodollar Loans before the end of the Interest
Period applicable thereto.

         (b)  On the last Business Day of each Fiscal Quarter, Borrower will,
in addition to paying any interest then due on the Loans, repay a portion of
the outstanding principal balance of the Loans in the amount set out below
opposite the time period in which such Fiscal Quarter occurs:

In addition, Borrower will make a final principal payment on the Loans on
November 30, 2002, in an amount equal to $28,000,000 (or, if different, the
remaining outstanding principal balance of the Loans).

         (c)  Each prepayment of principal under this section, whether optional
or mandatory, may but need not be accompanied by all interest then accrued and
unpaid on the principal so prepaid.  Any principal or interest prepaid pursuant
to this section shall be in addition to, and not in lieu of, all payments
otherwise required to be paid under the Loan Documents at the time of such
prepayment.

         Section 2.7.  Funding Required Prior to Execution of Indenture.  At
least one Business Day prior to the execution of the Indenture (or any other
documents constituting a guaranty of the Public Notes) by any Restricted
Subsidiary, Borrower will borrow the initial Loans under Section 2.2.  Until
such time as Borrower actually pays such funds to consummate the Acquisition,
Borrower will use such funds to purchase commercial paper from ING (U.S.)
Funding Corp. on an overnight basis and will pledge such commercial paper to
Collateral Agent under the Borrower Security Agreement.  If Borrower has not
consummated the Acquisitions within three Business Days thereafter, Borrower
will upon request by Agent liquidate such commercial paper and prepay the Loans
in full.

ARTICLE III - Payments to Lenders

         Section 3.1.  General Procedures.  Borrower will make each payment
which it owes under the Loan Documents to Agent for the account of the Bank
Party to whom such payment is owed.  Each such payment must be received by
Agent not later than noon, New York, New York time, on the date such payment
becomes due and payable, in lawful money of the United States of America,
without set-off, deduction or counterclaim, and in immediately available funds.
Any payment received by Agent after such time will be deemed to have been made
on the next following Business Day.  Should any such payment become due and
payable on a day other than a Business Day, the maturity of such payment shall
be extended to the next succeeding Business Day, and, in the case of a payment
of principal or past due interest, interest shall accrue and be payable thereon
for the period of such extension as provided in the Loan Document under which
such payment is due.  Each payment under a Loan Document shall be due and
payable at the place provided therein and, if no specific place of payment is
provided, shall be due and payable at the place of payment of Agent's Note.
When Agent collects or receives money on account of the Obligations, Agent
shall distribute all money so collected or received, and each Bank Party shall
apply all such money so distributed, as follows:

                 (a)  first, for the payment of all Obligations which are then
         due (and if such money is insufficient to pay all such Obligations,
         first to any reimbursements due Agent or Collateral Agent under
         Section 10.4 and then to the partial payment of all other Obligations
         then due in proportion to the amounts thereof, or as the Bank Parties
         shall otherwise agree);

                 (b)  then for the prepayment of amounts owing under the Loan
         Documents (other than principal on the Notes) if so specified by
         Borrower;

                 (c)  then for the prepayment of principal on the Notes,
         together with accrued and unpaid interest on the principal so prepaid;
         and

                 (d)  last, for the payment or prepayment of any other
         Obligations.

All payments applied to principal or interest on any Note shall be applied
first to any interest then due and payable, then to principal then due and
payable, and last to any prepayment of principal and interest in compliance
with Section 2.7.  All distributions of amounts described in any of subsections
(b), (c) or (d) above shall be made by Agent pro rata to each Bank Party then
owed Obligations described in such subsection in proportion to all amounts owed
to all Bank Parties which are described in such subsection.

         Section 3.2.  Capital Reimbursement.  If either (a) the introduction
of any change in or in the interpretation of any Law, or (b) the introduction
of any new request, directive or guideline from any central bank or other
governmental authority (whether or not having the force of Law) affects or
would affect the amount of capital required or expected to be maintained by any
Bank Party or any corporation controlling any Bank Party, then, upon demand by
such Bank Party, Borrower will pay to Agent for the benefit of such Bank Party,
from time to time as specified by such Bank Party, such additional amount or
amounts which such Bank Party shall determine to be appropriate to





                                       17
<PAGE>   22
compensate such Bank Party or any corporation controlling such Bank Party in
light of such circumstances, to the extent that such Bank Party reasonably
determines that the amount of any such capital would be increased or the rate
of return on any such capital would be reduced by or in whole or in part based
on the existence of the amount of such Bank Party's Loans or commitments under
this Agreement.  Notwithstanding anything herein to the contrary, Borrower
shall not be required to reimburse any Bank Party for any such amounts incurred
more than 90 days prior to such Bank Party's demand therefor to Borrower.

         Section 3.3.  Increased Cost of Eurodollar Loans.  If any applicable
domestic or foreign Law (whether now in effect or hereinafter enacted or
promulgated, including Regulation D) or any interpretation or administration
thereof by any governmental authority charged with the interpretation or
administration thereof (whether or not having the force of Law):

                 (a)      shall change the basis of taxation of payments to any
         Bank Party of any principal, interest, or other amounts attributable
         to any Eurodollar Loan or otherwise due under this Agreement in
         respect of any Eurodollar Loan (other than taxes imposed on the
         overall net income of such Bank Party by the jurisdiction in which
         such Bank Party or its Lending Office is located); or

                 (b)      shall change such as to impose any reserve, special
         deposit or similar requirements in respect of any Eurodollar Loan
         (excluding those for which such Bank Party is fully compensated
         pursuant to adjustments made in the definition of Eurodollar Rate) or
         against assets of, deposits with or for the account of, or credit
         extended by, such Bank Party; or

                 (c)      shall changes such as to impose on any Bank Party or
         on the interbank eurocurrency deposit market any other condition
         affecting any Eurodollar Loan, the result of which is to increase the
         cost to any Bank Party of funding, maintaining, issuing or
         participating in any Eurodollar Loan or to reduce the amount of any
         sum receivable by any Bank Party in respect of any Eurodollar Loan by
         an amount deemed by such Bank Party to be material,

then such Bank Party shall promptly notify Agent and Borrower in writing of the
happening of such event and of the amount required to compensate such Bank
Party for such event, whereupon (i) Borrower shall pay such amount to Agent for
the account of such Bank Party and (ii) Borrower may elect, by giving to Agent
and such Bank Party not less than three Business Days' notice, to convert all
(but not less than all) of any such Eurodollar Loan into a Base Rate Loan.
Notwithstanding anything herein to the contrary, Borrower shall not be required
to compensate any Bank Party for any such amounts incurred more than 90 days
prior to such Bank Party's notice thereof to Borrower.

         Section 3.4.  Availability.  If (a) any change in applicable Laws, or
in the interpretation or administration thereof of or in any jurisdiction
whatsoever, domestic or foreign, shall make it unlawful or impracticable for
any Bank Party to fund or maintain Eurodollar Loans, or shall materially
restrict the authority of any Bank Party to purchase or take offshore deposits
of dollars (i.e., "eurodollars"), or (b) any Bank Party determines that
matching deposits appropriate to fund or





                                       18
<PAGE>   23
maintain any Eurodollar Loan are not available to it, or (c) any Bank Party
determines that the formula for calculating the Eurodollar Rate does not fairly
reflect the cost to such Bank Party of making or maintaining loans based on
such rate, then, upon notice by such Bank Party to Borrower and Agent,
Borrower's right to elect Eurodollar Loans from such Bank Party shall be
suspended to the extent and for the duration of such illegality,
impracticability or restriction and all Eurodollar Loans of such Bank Party
which are then outstanding or are then the subject of any Borrowing Notice and
which cannot lawfully or practicably be maintained or funded shall immediately
become or remain part of such Bank Party's Base Rate Loan.  Borrower agrees to
indemnify each Bank Party and hold it harmless against all costs, expenses,
claims, penalties, liabilities and damages which may result from any such
change in Law.

         Section 3.5.  Funding Losses.  In addition to its other obligations
hereunder, Borrower will indemnify each Bank Party against, and reimburse each
Bank Party on demand for, any loss or expense incurred or sustained by such
Bank Party (including any loss or expense incurred by reason of the liquidation
or reemployment of deposits or other funds acquired by a Bank Party to fund or
maintain Eurodollar Loans), upon presentation of reasonable documentation
thereof, as a result of (a) any payment or prepayment (whether authorized or
required hereunder or otherwise) of all or a portion of a Eurodollar Loan on a
day other than the day on which the applicable Interest Period ends, (b) any
payment or prepayment, whether required hereunder or otherwise, of a Loan made
after the delivery, but before the effective date, of a Borrowing Notice, if
such payment or prepayment prevents such Borrowing Notice from becoming fully
effective, (c) the failure of any Loan to be made or of any Borrowing Notice to
become effective due to any condition precedent not being satisfied or due to
any other action or inaction of any Related Person, or (d) any conversion
(whether authorized or required hereunder or otherwise) of all or any portion
of any Eurodollar Loan into a Base Rate Loan or into a different Eurodollar
Loan on a day other than the day on which the applicable Interest Period ends.

         Section 3.6.  Reimbursable Taxes.  Borrower covenants and agrees that:

                 (a)      Borrower will indemnify each Bank Party against and
         reimburse each Bank Party for all present and future income, stamp and
         other taxes, levies, costs and charges whatsoever imposed, assessed,
         levied or collected on or in respect of this Agreement or any Loans or
         payments hereunder (whether or not legally or correctly imposed,
         assessed, levied or collected), excluding, however, any taxes imposed
         on or measured by the overall net income of such Bank Party by the
         jurisdiction in which such Bank Party or its Lending Office is located
         (all such non-excluded taxes, levies, costs and charges being
         collectively called "Reimbursable Taxes" in this section).

                 (b)      All payments on account of the principal of, and
         interest on, each Bank Party's Loans and Note, and all other amounts
         payable by Borrower to any Bank Party hereunder, shall be made in full
         without set-off or counterclaim and shall be made free and clear of
         and without deductions or withholdings of any nature by reason of any
         Reimbursable Taxes, all of which will be for the account of Borrower.
         In the event of Borrower being compelled by Law to make any such
         deduction or withholding from any payment to any Bank Party, Borrower
         shall pay on the due date of such payment, by way of additional
         interest, such additional amounts as are needed to cause the amount
         receivable by such Bank Party after





                                       19
<PAGE>   24
         such deduction or withholding to equal the amount which would have
         been receivable in the absence of such deduction or withholding.  If
         Borrower should make any deduction or withholding as aforesaid,
         Borrower shall within 60 days thereafter forward to such Bank Party an
         official receipt or other official document evidencing payment of such
         deduction or withholding.

                 (c)      If Borrower is ever required to pay any Reimbursable
         Tax with respect to any Eurodollar Loan from a Bank Party, Borrower
         may elect, by giving to Agent and such Bank Party not less than three
         Business Days' notice, to convert all (but not less than all) of such
         Eurodollar Loan into a part of such Bank Party's Base Rate Loan, but
         such election shall not diminish Borrower's obligation to pay all
         Reimbursable Taxes.

                 (d)  Notwithstanding the foregoing provisions of this section,
         Borrower shall be entitled, to the extent it is required to do so by
         Law, to deduct or withhold (and not to make any indemnification or
         reimbursement for) income or other similar taxes imposed by the United
         States of America (other than any portion thereof attributable to a
         change in federal income tax Laws effected after the date hereof) from
         interest, fees or other amounts payable hereunder for the account of
         any Bank Party, other than a Bank Party (i) who is a U.S. person for
         Federal income tax purposes or (ii) who has the Prescribed Forms on
         file with Agent (with copies provided to Borrower) for the applicable
         year to the extent deduction or withholding of such taxes is not
         required as a result of the filing of such Prescribed Forms, provided
         that if Borrower shall so deduct or withhold any such taxes, it shall
         provide a statement to Agent and such Bank Party, setting forth the
         amount of such taxes so deducted or withheld, the applicable rate and
         any other information or documentation which such Bank Party may
         reasonably request for assisting such Bank Party to obtain any
         allowable credits or deductions for the taxes so deducted or withheld
         in the jurisdiction or jurisdictions in which such Bank Party is
         subject to tax.  As used in this section, "Prescribed Forms" means
         such duly executed forms or statements, and in such number of copies,
         which may, from time to time, be prescribed by Law and which, pursuant
         to applicable provisions of (x) an income tax treaty between the
         United States and the country of residence of the Bank Party
         providing the forms or statements, (y) the Internal Revenue Code of
         1986, as amended from time to time, or (z) any applicable rules or
         regulations thereunder, permit Borrower to make payments hereunder for
         the account of such Bank Party free of such deduction or withholding
         of income or similar taxes.

Notwithstanding anything herein to the contrary, Borrower shall not be required
to reimburse any Bank Party for any Reimbursable Taxes which have become owing
more than 90 days prior to such Bank Party's notice thereof to Borrower.

         Section 3.7.  Change of Applicable Lending Office.  Each Bank Party
agrees that, upon the occurrence of any event giving rise to the operation of
Sections 3.2 through 3.6 with respect to such Bank Party, it will, if requested
by Borrower, use reasonable efforts (subject to overall policy considerations
of such Bank Party) to designate another Lending Office, provided that such
designation is made on such terms that such Bank Party and its Lending Office
suffer no economic, legal or regulatory disadvantage, with the object of
avoiding the consequence of the event giving rise





                                       20
<PAGE>   25
to the operation of any such section.  Nothing in this section shall affect or
postpone any of the obligations of Borrower or the rights of any Bank Party
provided in Sections 3.2 through 3.6.

         Section 3.8.  Replacement of Lenders.  If any Lender seeks
reimbursement for increased costs under Sections 3.2 through 3.6, then within
ninety days thereafter -- provided no Event of Default then exists -- Borrower
shall have the right (unless such Lender withdraws its request for additional
compensation) to replace such Lender by requiring such Lender to assign its
Loans and Notes and its commitments hereunder to an Eligible Transferee
reasonably acceptable to Agent and to Borrower, provided that: (i) all
Obligations of Borrower owing to such Lender being replaced (including such
increased costs, but excluding principal and accrued interest on the Notes
being assigned) shall be paid in full to such Lender concurrently with such
assignment, and (ii) the replacement Eligible Transferee shall purchase the
Note being assigned by paying to such Lender a price equal to the principal
amount thereof plus accrued and unpaid interest thereon.  In connection with
any such assignment Borrower, Agent, such Lender and the replacement Eligible
Transferee shall otherwise comply with Section 10.5.  Notwithstanding the
foregoing rights of Borrower under this section, however, Borrower may not
replace any Lender which seeks reimbursement for increased costs under Section
3.2 through 3.6 unless Borrower is at the same time replacing all Lenders which
are then seeking such compensation.

ARTICLE V - Representations and Warranties

         To confirm each Bank Party's understanding concerning Borrower and
Borrower's business, properties and obligations and to induce each Bank Party
to enter into this Agreement and to extend credit hereunder, Borrower
represents and warrants to each Bank Party that:

         Section 5.1.  No Default.  No event has occurred and is continuing
which constitutes a Default.

         Section 5.2.  Organization and Good Standing.  Each Related Person is
duly organized, validly existing and in good standing under the Laws of its
jurisdiction of organization, having all powers required to carry on its
business and enter into and carry out the transactions contemplated hereby.
Each Related Person is duly qualified, in good standing, and authorized to do
business in all other jurisdictions wherein the failure to so qualify would
present a reasonable possibility of causing a Material Adverse Change.

         Section 5.3.  Authorization.  Each Related Person has duly taken all
action necessary to authorize the execution and delivery by it of the Loan
Documents to which it is a party and to authorize the consummation of the
transactions contemplated thereby and the performance of its obligations
thereunder.  Borrower is duly authorized to borrow funds hereunder.

         Section 5.4.  No Conflicts or Consents.  The execution and delivery by
the various Related Persons of the Loan Documents to which each is a party, the
performance by each of its obligations under such Loan Documents, and the
consummation of the transactions contemplated by the various Loan Documents, do
not and will not (i) conflict with any provision of (1) any domestic or foreign
Law, (2) the articles or certificate of incorporation or organization, bylaws,
charter, or partnership agreement or certificate of any Related Person, or (3)
any agreement, judgment, license, order or permit applicable to or binding upon
any Related Person, (ii) result in the acceleration of any Indebtedness owed by
any Related Person, or (iii) result in or require the creation of any Lien upon
any assets or properties of any Related Person except as expressly contemplated
in the Loan Documents.  Except as expressly contemplated in the Loan Documents,
no consent, approval, authorization or order of, and no notice to or filing
with, any court or governmental authority or third party is required in
connection with the execution, delivery or performance by any Related Person of
any Loan Document or to consummate any transactions contemplated by the Loan
Documents.

         Section 5.5.  Enforceable Obligations.  This Agreement is, and the
other Loan Documents when duly executed and delivered will be, legal, valid and
binding obligations of each Related Person which is a party hereto or thereto,
enforceable in accordance with their terms except as such enforcement may be
limited by bankruptcy, insolvency or similar Laws of general application
relating to the enforcement of creditors' rights.





                                       24

         Section 5.6.  Initial Financial Statements; Solvency.  Borrower has
heretofore delivered to Agent and each Lender true, correct and complete copies
of the Initial Financial Statements.  The Initial Financial Statements were
prepared in accordance with GAAP and fairly present the matters reported on
therein.  Since the date of the Initial Financial Statements, no Material
Adverse Change has occurred and is continuing.  Borrower is not insolvent on
the date hereof.  Borrower's capital is adequate for the businesses in which
Borrower is engaged and intends to be engaged.  Borrower has not incurred
(whether hereby or otherwise), nor does Borrower intend to incur or believe
that it will incur, debts which will be beyond its ability to pay as such debts
mature.

         Section 5.7.  Full Disclosure.  Neither the Offering Circular nor any
certificate or other written information delivered herewith or heretofore by
any Related Person to any Bank Party in connection with the negotiation of this
Agreement or in connection with any transaction contemplated hereby contains
any untrue statement of a material fact or omits to state any material fact
known to any Related Person (other than industry-wide risks normally associated
with the types of businesses conducted by the Related Persons) necessary to
make the statements contained herein or therein not misleading as of the date
made or deemed made.  There is no fact known to Borrower or any Restricted
Subsidiary (other than industry-wide risks normally associated with the types
of businesses conducted by Borrower and Restricted Subsidiaries) that has not
been disclosed to each Bank Party in writing which in any manner presents a
reasonable possibility of resulting in a Material Adverse Change.

         Section 5.8.  Litigation.  Except as disclosed in the Initial
Financial Statements or in the Disclosure Schedule, there are no actions, suits
or legal, equitable, arbitrative or administrative proceedings pending (or to
the knowledge of any Related Person threatened) against any Related Person
before any federal, state, municipal or other court, department, commission,
body, board, bureau, agency, or instrumentality (whether domestic or foreign)
which present a reasonable possibility of resulting in a Material Adverse
Change.  Except as disclosed in the Initial Financial Statements or in the
Disclosure Schedule, there are no outstanding judgments, injunctions, writs,
rulings or orders by any such governmental entity against any Related Person or
any Related Person's stockholders, partners, directors or officers which
present a reasonable possibility of resulting in a Material Adverse Change.

         Section 5.9.  Labor Disputes and Acts of God.  Except as disclosed in
the Disclosure Schedule or a Disclosure Report, neither the business nor the
properties of any Related Person has been affected by any fire, explosion,
accident, strike, lockout or other labor dispute, drought, storm, hail,
earthquake, embargo, act of God or of the public enemy or other casualty
(whether or not covered by insurance) in any way which presents a reasonable
possibility of resulting in a Material Adverse Change.

         Section 5.10.  ERISA Plans and Liabilities.  All currently existing
ERISA Plans are listed in the Disclosure Schedule or a Disclosure Report.
Except as disclosed in the Initial Financial Statements or in the Disclosure
Schedule or a Disclosure Report, no Termination Event has occurred with respect
to any ERISA Plan and the Related Persons are in compliance with ERISA in all
material respects.  No Related Person is required to contribute to, or has any
other absolute or contingent liability in respect of, any "multiemployer plan"
as defined in Section 4001 of ERISA.  Except as set forth in the Disclosure
Schedule or a Disclosure Report:  (i) no "accumulated funding





                                       25
<PAGE>   30
deficiency" (as defined in Section 412(a) of the Internal Revenue Code of 1986,
as amended) exists with respect to any ERISA Plan, whether or not waived by the
Secretary of the Treasury or his delegate, and (ii) the current value of each
ERISA Plan's benefits does not exceed the current value of such ERISA Plan's
assets available for the payment of such benefits by more than $1,000,000.

         Section 5.11.  Environmental and Other Laws.  As used in this section:
"CERCLA" means the Comprehensive Environmental Response, Compensation and
Liability Act of 1980, as amended, "CERCLIS" means the Comprehensive
Environmental Response, Compensation and Liability Information System List of
the Environmental Protection Agency, and "Release" has the meaning given such
term in 42 U.S.C. Section  9601(22).  Except as set forth in the Disclosure
Schedule or a Disclosure Report:

                 (a)  The Related Persons are conducting their businesses in
         compliance with all applicable federal, state and local Laws,
         including Environmental Laws, and have all permits, licenses and
         authorizations required in connection with the conduct of their
         businesses, except to the extent failure to have any such permit,
         license or authorization does not in any way present a reasonable
         possibility of resulting in a Material Adverse Change.  Each Related
         Person is in compliance with the terms and conditions of all such
         permits, licenses and authorizations, and is also in compliance with
         all other limitations, restrictions, conditions, standards,
         prohibitions, requirements, obligations, schedules and timetables
         contained in any applicable Environmental Law or in any regulation,
         code, plan, order, decree, judgment, injunction, notice or demand
         letter issued, entered, promulgated or approved thereunder, except to
         the extent failure to comply does not in any way present a reasonable
         possibility of resulting in a Material Adverse Change..

         citation, summons or order has been issued, no complaint has been
         filed, no penalty has been assessed, and no investigation or review is
         pending or threatened by any governmental agency or entity or any
         other Person with respect to (i) any alleged generation, treatment,
         storage, recycling, transportation, disposal, or Release of any
         Hazardous Materials in a material amount, either by any Related Person
         or on any property owned by any Related Person, (ii) any material
         remedial action which might be needed to respond to any such alleged
         generation, treatment, storage, recycling, transportation, disposal,
         or Release, or (iii) any alleged failure by any Related Person to have
         any material permit, license or authorization required in connection
         with the conduct of its business or with respect to any such
         generation, treatment, storage, recycling, transportation, disposal,
         or Release.

                 (d)  No Related Person has handled any Hazardous Materials,
         other than as a generator, on any properties now or previously owned
         or leased by any Related Person to an extent that such handling
         presents a reasonable possibility of resulting in a Material Adverse
         Change; and

                 owned or leased by any Related Person to an extent that such

         Environmental Laws on any of the properties owned or leased by any
         Related Person, and no government actions have been taken or are in

         properties owned by it in any deed to such properties.

         mortgage, agreement, contract or other instrument to which any of them
         is a party or by which any of them or any of their properties is
         bound, if such default presents a reasonable possibility of resulting
         in a Material Adverse Change.

                 (d)  the occurrence of any Termination Event.

                 (e)  any claim of $2,000,000 or more, any notice of potential
         liability under any Environmental Laws which might exceed such amount,
         or any other material adverse claim asserted against any Related
         Person or with respect to any Related Person's properties.

                 (f)  the filing of any suit or proceeding against any Related
         Person in which an adverse decision would present a reasonable
         possibility of resulting in a Material Adverse Change.

Upon the occurrence of any of the foregoing the Related Persons will take all
necessary or appropriate steps to remedy promptly any such Material Adverse
Change, Default, acceleration, default or Termination Event, to protect against
any such adverse claim, to defend any such suit or proceeding, and to resolve
all controversies on account of any of the foregoing.  Borrower will also
notify Agent and Agent's counsel in writing at least twenty Business Days prior
to the date that (i) any Related Person changes its name or the location of its
chief executive office or principal place of business or the place where it
keeps its books and records concerning the Collateral, or (ii) the ownership of
any Collateral is transferred from one Related Person to another Related
Person, and Borrower will with such notice either furnish any necessary
financing statement amendments and other documents as may be required by
Sections 6.15 and 6.15 or request Agent and its counsel to prepare the same.

         Section 6.5.  Maintenance of Properties.  Each Related Person will
maintain, preserve, protect, and keep all Collateral and all other property
used or useful in the conduct of its business in good condition as required to
conduct its business and in material compliance with all applicable Laws, and
will from time to time make all repairs, renewals and replacements needed to
enable the business and operations carried on in connection therewith to be
promptly and advantageously conducted at all times.

         Section 6.6.  Maintenance of Existence and Qualifications.  Each
Related Person will maintain and preserve its existence and its rights and
franchises in full force and effect and will qualify to do business in all
states or jurisdictions where required by applicable Law, except where





                                       31
<PAGE>   36
the failure so to qualify will not cause any Material Adverse Change or
adversely affect the value of the Collateral.

         Section 6.7.  Payment of Trade Liabilities, Taxes, etc.  Each Related
Person will (a) timely file all required tax returns; (b) timely pay all taxes,
assessments, and other governmental charges or levies imposed upon it or upon
its income, profits or property; (c) within 120 days after the same become due,
pay all Liabilities owed by it on ordinary trade terms to vendors, suppliers
and other Persons providing goods and services used by it in the ordinary
course of its business; (d) pay and discharge when due all other Liabilities
now or hereafter owed by it; and (e) maintain appropriate accruals and reserves
for all of the foregoing in accordance with GAAP.  Each Related Person may,
however, delay paying or discharging any of the foregoing so long as it is in
good faith contesting the validity thereof by appropriate proceedings and has
set aside on its books adequate reserves therefor.

         Section 6.8.  Insurance.

         (a)  Borrower and the other Related Persons will at all times
maintain, with financially sound and reputable insurers, casualty, liability
and other insurance substantially in accordance with the minimum coverages set
out in Schedule 3, together with such additional insurance as may from time to
time be carried by similar Persons engaged in similar businesses.  Any
insurance policies covering Collateral shall be endorsed to provide for payment
of losses to Collateral Agent as its interests may appear and to provide that
such policies may not be cancelled or reduced or affected in any material
manner for any reason without fifteen days prior notice to Collateral Agent.
(As used in this Section 6.8, "Collateral" shall include any assets of any
Exempt Foreign Subsidiaries.)

         (b)  Borrower will furnish to Agent and Collateral Agent a statement
respecting any loss or damage to any Collateral with an aggregate value in
excess of $1,000,000 promptly after Borrower obtains knowledge of such loss or
damage.  Borrower will promptly reinvest all proceeds of insurance which it
receives pursuant to this section into the businesses of Borrower and the
Restricted Subsidiaries or, alternatively, promptly use such proceeds to make
voluntary prepayments hereunder.  Neither Borrower nor any Restricted
Subsidiary shall declare or agree with any underwriters that any Collateral is
a constructive or compromised, agreed or arranged constructive total loss
without the prior written consent of Collateral Agent.

         (c)  Subject to subsection (d) below: (i) any loss under any insurance
on any Collateral with respect to protection and indemnity risks may be paid
directly to Borrower or the relevant Restricted Subsidiary to reimburse it for
any loss, damage or expense incurred by it and covered by such insurance or to
the Person to whom any liability covered by such insurance has been incurred,
and (ii) in the case of any loss (other than a loss covered by clause (i)
above) under any insurance with respect to any Collateral involving any damage
to any Collateral, the underwriters may pay directly for the repair, salvage or
other charges involved or, if Borrower or such Restricted Subsidiary shall have
first fully repaired the damage or paid all of the salvage or other charges,
may pay Borrower or such Restricted Subsidiary as reimbursement therefor.  Any
loss covered by this subsection which is paid to Collateral Agent but which
might have been paid, in accordance with the provisions of this subsection,
directly to Borrower or such Restricted Subsidiary or others, shall be paid by
Collateral Agent to, or as directed by, Borrower or such Restricted Subsidiary.





                                       32
<PAGE>   37
         (d)  Notwithstanding the foregoing, all insurance payments made with
respect to Collateral during the continuance of any Event of Default shall be
paid by the underwriters directly to Collateral Agent for payment on to Agent
and to the Agent under the Revolving Credit Agreement for application, pursuant
to the Collateral Agency Agreement, to the Obligations and to the obligations
owing under the Term Loan Agreement.  In addition, in the event of cumulative
losses of $15,000,000 or more in any Fiscal Year with respect to Collateral
(and regardless of whether any Event of Default then exists), all insurance
payments for losses in excess of such amount shall (unless otherwise agreed by
Borrower, Majority Lenders, and "Majority Lenders" under the Revolving Credit
Agreement, which agreement shall not unreasonably be withheld) be paid to
Collateral Agent for payment on to Agent and to the Agent under the Revolving
Credit Agreement for application, pursuant to the Collateral Agency Agreement,
to the Obligations and to the obligations owing under the Term Loan Agreement.

         (e)  All funds received in the event that any Collateral is abandoned,
condemned as a prize, seized, lost, requisitioned, embargoed, forfeited, put up
for auction or bottomried, or disappears, or otherwise actually, constructively
or by arrangement condemned, seized or requisitioned, then all governmental
awards, insurance coverage, or other receipts on account of such event shall be
deemed to be, and handled in the same way as, insurance proceeds under the
foregoing provisions of this section.

         Section 6.9.  Performance on Borrower's Behalf.  If Borrower or any
Restricted Subsidiary fails to pay any taxes, insurance premiums, expenses,
attorneys' fees or other amounts it is required to pay under any Loan Document,
Agent or Collateral Agent may pay the same.  Borrower shall immediately
reimburse Agent or Collateral Agent for any such payments, and the such
reimbursement obligation shall be due and payable on the date such amount is
paid by Agent or Collateral Agent.

         Section 6.10.  Interest.  Borrower hereby promises to each Bank Party
to pay interest at the Default Rate on all Obligations (including Obligations
to pay fees and reimbursement or indemnification obligations) which Borrower
has in this Agreement promised to pay to such Bank Party and which are not paid
when due.  Such interest shall accrue from the date such Obligations become due
until they are paid.

         Section 6.11.  Compliance with Agreements and Law.  Borrower and each
Restricted Subsidiary will perform all material obligations it is required to
perform under the terms of each indenture, mortgage, deed of trust, security
agreement, lease, franchise, agreement, contract or other instrument or
obligation to which it is a party or by which it or any of its properties is
bound.  Borrower and each Restricted Subsidiary will conduct its business and
affairs in compliance with all Laws applicable thereto.

         Section 6.12.  Environmental Matters; Environmental Reviews.

                 (a)  Each Related Person will comply in all material respects
         with all Environmental Laws now or hereafter applicable to such
         Related Person and shall obtain, at or prior to the time required by
         applicable Environmental Laws, all environmental, health and safety





                                       33
<PAGE>   38
         permits, licenses and other authorizations materially necessary for
         its operations and will maintain such authorizations in full force and
         effect.

                 (b)  Borrower will promptly furnish to Agent all written
         notices of violation, orders, claims, citations, complaints, penalty
         assessments, suits or other proceedings received by Borrower, or of
         which it has notice, pending or threatened against Borrower, by any
         governmental authority with respect to any alleged material violation
         of or non-compliance with any Environmental Laws or any material
         permits, licenses or authorizations in connection with its ownership
         or use of its properties or the operation of its business.

                 (c)  Borrower will promptly furnish to Agent all requests for
         information, notices of claim, demand letters, and other
         notifications, received by Borrower in connection with its ownership
         or use of its properties or the conduct of its business, relating to
         any material potential responsibility with respect to any
         investigation or clean-up of Hazardous Material at any location.

         Section 6.13.  Evidence of Compliance.  Each Related Person will
furnish to Agent at such Related Person's or Borrower's expense all evidence
which Agent from time to time reasonably requests in writing as to the accuracy
and validity of or compliance with all representations, warranties and
covenants made by any Related Person in the Loan Documents, the satisfaction of
all conditions contained therein, and all other matters pertaining thereto.

         Section 6.14.  Subsidiary Guaranties; Exempt Foreign Subsidiaries.
Except for (a) Restricted Subsidiaries which do not possess $50,000 or more of
assets (excluding assets consisting of intercompany receivables existing on the
date hereof which have been subordinated pursuant to the Intercompany
Subordination Agreement) and (b) Restricted Subsidiaries which Agent has
requested be designated an Exempt Foreign Subsidiary under the Indenture, each
Restricted Subsidiary now existing or created, acquired or coming into
existence after the date hereof shall, promptly upon request therefor by Agent,
execute and deliver to Collateral Agent an absolute and unconditional Guaranty
of the timely repayment of the Obligations and the due and punctual performance
of the obligations of Borrower hereunder.  Borrower will cause each Guarantor
Subsidiary to deliver to Agent, simultaneously with its delivery of such a
guaranty, written evidence satisfactory to Agent and its counsel that such
Guarantor Subsidiary has taken all corporate or partnership action necessary to
duly approve and authorize its execution, delivery and performance of such
Guaranty and any other documents which it is required to execute.  If Agent
requests that any Restricted Subsidiary be designated an Exempt Foreign
Subsidiary under the Indenture, Borrower will promptly make such designation
(to the extent it is able to do so under the Indenture), and Borrower will not
allow any such Exempt Foreign Subsidiary to be or remain obligated on any
guaranty of the Public Notes.  If Agent requests that any designation of an
Exempt Foreign Subsidiary be revoked under the Indenture, Borrower will
promptly make such revocation, to the extent it is able to do so without
violation of the Indenture and the Revolving Credit Agreement.

         Section 6.15.  Agreement to Provide Collateral.

         (a)  Borrower will cause at least eighty percent (80%) in value of the
assets of Borrower and the Restricted Subsidiaries to at all times be subject
to first priority, perfected Liens in favor of





                                       34
<PAGE>   39
Collateral Agent which secure the Obligations, provided that, to the extent
that assets outside the United States representing ten percent (10%) or less in
value of Parker's and the Restricted Subsidiaries' total assets are held by
Exempt Foreign Subsidiaries, such assets shall nonetheless count toward
achieving such 80% in value threshold if (i) the stock of such Exempt Foreign
Subsidiaries is subject to first priority, perfected Liens in favor of
Collateral Agent which secure the Obligations, and (ii) such Exempt Foreign
Subsidiaries have no Indebtedness and are not guarantors of the Public Notes or
of the Revolving Credit Agreement.

         (b)  In addition to the foregoing, Borrower will deliver and to cause
its Restricted Subsidiaries to deliver, to further secure the Obligations
whenever requested by Agent or Collateral Agent in its sole and absolute
discretion, deeds of trust, mortgages, chattel mortgages, security agreements,
financing statements and other Security Documents in form and substance
satisfactory to Agent or Collateral Agent for the purpose of granting,
confirming, and perfecting first and prior liens or security interests in any
real or personal property now owned or hereafter acquired by Borrower or any
Restricted Subsidiary.

         Section 6.16.  Perfection and Protection of Security Interests and
Liens.  Borrower will from time to time deliver, and cause the Restricted
Subsidiaries to deliver, to Collateral Agent any financing statements,
continuation statements, extension agreements and other documents, properly
completed and executed (and acknowledged when required) and in form and
substance satisfactory to Agent or Collateral Agent, which Agent or Collateral
Agent in good faith requests for the purpose of perfecting, confirming, or
protecting any Liens or other rights in Collateral securing any Obligations.

         Section 6.17.  Designated Accounts.  Borrower shall cause, and shall
cause each Restricted Subsidiary to cause, all payors on accounts owing to the
Borrower or such Restricted Subsidiary to remit all payments on such accounts
either (a) by wire transfer into a Designated Account or (b) by check mailed to
a lockbox maintained in connection with a Designated Account.  Designated
Accounts shall include up to six deposit accounts specified from time-to-time
by Borrower for itself and the Restricted Subsidiaries by notice to Agent and
Collateral Agent specifying the name of the bank and the account number.
Borrower shall cause, and shall cause each Restricted Subsidiary to cause, each
Designated Account to be subject to a pledge agreement in form and substance
satisfactory to Collateral Agent, provided, however, that so long as no Event
of Default has occurred and is continuing, Lender shall not exercise control
over such account and the Borrower shall continue to have dominion over the
Designated Account including the power to make withdrawals from any such
Designated Account.  Borrower shall not deposit into the Designated Accounts
monies of Borrower or any Restricted Subsidiary which are not proceeds of
Collateral.

         Section 6.18.  Notice to Account Debtors.  Borrower will, and will
cause each Restricted Subsidiary (excluding Exempt Foreign Subsidiaries) to,
deliver to Collateral Agent duly executed letters notifying each account debtor
on any of the Collateral earned in Columbia or Peru (or any other jurisdiction
outside the United States which Collateral Agent from time to time designates)
of the assignment of such account debtor's monetary obligations to Collateral
Agent to secure the Obligations owing to the Lenders under this Agreement and
the Revolving Credit Agreement.

ARTICLE VII - Negative Covenants of Borrower

         To conform with the terms and conditions under which each Bank Party
is willing to have credit outstanding to Borrower, and to induce each Bank
Party to enter into this Agreement and make the Loans, Borrower warrants,
covenants and agrees that until the full and final payment of the Obligations
and the termination of this Agreement, unless Majority Lenders have previously
agreed otherwise:

         Section 7.1.  Indebtedness.  Neither Borrower nor any Restricted

                 (a)  the Obligations.

                 (b)  Indebtedness owing under the Revolving Credit Agreement.

                 (c)  Indebtedness owing under the Public Notes.

                 (d)      unsecured Indebtedness owing by any Related Person to

         Obligations pursuant to the Intercompany Subordination Agreement.

                 (e)  Indebtedness outstanding under the letters of credit,
         instruments and agreements described on the Disclosure Schedule,
         excluding any renewals or extensions of such Indebtedness (except as
         expressly allowed on the Disclosure Schedule).

                 (f)  any obligation of Borrower, as required pursuant to the
         Mallard Acquisition Agreement, to redeem the preferred stock issued
         thereunder.

                 (g)  miscellaneous items of Indebtedness, not for borrowed
         money and not described in the preceding subsections of this section,
         which do not in the aggregate (taking into account all such
         Indebtedness of Borrower and the Restricted Subsidiaries) exceed
         $1,000,000 at any time.

No Unrestricted Subsidiary will in any manner owe or be liable for any
Indebtedness unless (i) such Indebtedness is not a Liability, in whole or in
part, of Borrower or any Restricted Subsidiary, (ii) such Indebtedness is not
secured by any Lien on any assets or property of Borrower or any Restricted
Subsidiary, and (iii) no default on such Indebtedness would allow or require
the acceleration of Indebtedness owed by Borrower or any Restricted Subsidiary.

         Section 7.2.  Liens.  Neither Borrower nor any Restricted Subsidiary
will create, assume, allow or suffer to exist any Lien upon any of its
property, revenues or assets, whether now owned or hereafter acquired, except

                 (a)  Liens granted pursuant to any Loan Document to secure

         Borrower's Consolidated books.

                 (c)  inchoate Liens arising under ERISA to secure liabilities

         accordance with GAAP have been set aside on Borrower's Consolidated
         books.

         aggregate value of Cash Equivalents subject to such Liens may not
         exceed $5,000,000 at any time, and that Borrower and the Restricted
         Subsidiaries must, to the extent practical, use letters of credit
         permitted hereunder in place of such Liens.

                 (f)  judgment Liens, but only for so long as enforcement
         thereof is not allowed (whether by appeal and bonding, order of a
         court, agreement, or otherwise).

                 (g)  bankers' Liens and rights of setoff arising by operation
         of Law and burdening only deposit accounts or other accounts
         maintained with the financial institution holding such accounts,
         provided that each such account is maintained in the ordinary course
         of business and not with the intention of providing collateral to any
         such financial institution.

                 (h)  Liens listed on the Disclosure Schedule.

                 (i)  Liens on Cash Equivalents granted to Borrower's

Subsidiary is the surviving Person, or (ii) Borrower, so long as Borrower is
the surviving Person.  Borrower will not issue any securities other than shares
of its common stock and any options or warrants giving the holders thereof only
the right to acquire such shares, except that





                                       37
<PAGE>   42
Borrower may issue (1) the preferred stock required under the Mallard
Acquisition Agreement, and (2) other shares of preferred stock, provided that
Borrower has the unqualified right to make all dividend payments thereon using
additional shares of such preferred stock or of Borrower's common stock.  No
Restricted Subsidiary will issue any additional shares of its capital stock or
other securities or any options, warrants or other rights to acquire such
additional shares or other securities except to Borrower and only to the extent
not otherwise forbidden under the terms hereof.  No Restricted Subsidiary which
is a partnership, limited liability company, or similar entity will allow any
diminution of Borrower's interest (direct or indirect) therein.

         of business for fair consideration not in the aggregate in excess of
         $15,000,000 in any Fiscal Year, the sale of which will not materially
         impair or diminish the value of the Collateral or Borrower's
         Consolidated financial condition, business or operations, taken as a
         whole; provided that the proceeds of such sales must either be
         promptly reinvested in the businesses of Borrower and Restricted
         Subsidiaries or promptly used to make voluntary prepayments hereunder.

So long as no Default exists, Collateral Agent will at Borrower's request
release any Collateral sold, transferred, leased, exchanged, alienated or
disposed of pursuant to the foregoing provisions of this section.  Neither
Borrower nor any Restricted Subsidiary will sell, transfer or otherwise dispose

Subsidiary of Borrower may sell or issue its own capital stock to Borrower or a
Restricted Subsidiary to the extent not otherwise prohibited hereunder).

         the aggregate in any Fiscal Year, to redeem stock from its executives

         Subsidiaries which are either presently existing and wholly owned by
         Borrower (directly or indirectly) or hereafter organized and wholly
         and directly owned by Borrower, provided that if any such Restricted
         Subsidiary has assets of $50,000 or more, Agent must be given at least
         fifteen Business Days' advance notice of each investment in such
         Restricted Subsidiary and (i) if Agent requests that such Restricted
         Subsidiary be designated an Exempt Foreign Subsidiary under the
         Indenture and Borrower is able to do so under the Indenture, Borrower
         must so designate such Restricted Subsidiary at or before the time of
         such investment, and (ii) if Agent does not make any such request,
         such Restricted Subsidiary must become a Guarantor Subsidiary at or
         before the time of such investment.

                 (d)  acquisitions of Persons which become direct or indirect
         wholly-owned Restricted Subsidiaries of Borrower, or of discrete
         businesses which become owned in full by Borrower or a Restricted
         Subsidiary, provided that (i) Sections 6.14 and 6.15 are complied with
         at the time of each such acquisition, if applicable, and, (ii) no
         Default exists, either before or immediately after each such
         acquisition, and (iii) a senior officer of Borrower certifies to the
         Bank Parties that Borrower believes that such acquisition will not
         adversely affect Borrower's ability to remain in compliance herewith.

                 (e)  investments by Borrower in any Unrestricted Subsidiary
         (whether presently existing or hereafter owned or acquired), so long
         as all such investments are made with funds presently held by, or
         hereafter earned by, Unrestricted Subsidiaries or OnSite Technology,
         L.L.C. (provided that after the outstanding principal balance of the
         Loans has been reduced to $50,000,000 or less, Borrower may invest
         additional funds of up to $7,500,000 in Unrestricted Subsidiaries).

                 (f)  normal and prudent extensions of credit to customers
         buying goods and services in the ordinary course of business, which
         extensions shall not be for longer periods than those extended by
         similar businesses operated in a normal and prudent manner.

                 (g)  loans to employees of any Related Person, so long as the
         aggregate outstanding amount of all such loans made by all Related
         Persons does not exceed $2,000,000 at any time.

                 (h)  capital assets to be used in the businesses referred to
         in Section 7.6, provided that, with respect to any such acquisition of
         a capital asset costing $1,000,000 or more: (i) Sections 6.14 and 6.15
         are complied with at the time of such acquisition, if applicable, (ii)
         no Default exists, either before or immediately after such
         acquisition, and (iii) a senior officer of Borrower certifies to the
         Bank Parties that Borrower believes that such acquisition will not
         adversely affect Borrower's ability to remain in compliance herewith.

Notwithstanding the foregoing, unless Agent expressly requests that a
Restricted Subsidiary which already owns Subsidiaries be designated an Exempt
Foreign Subsidiary, no Exempt Foreign Subsidiary will own or acquire any
Subsidiaries or other equity interests.

         Section 7.8.  Transactions with Affiliates.  Neither Borrower nor any
Restricted Subsidiary will (a) sell, lease, transfer or otherwise dispose of
any of its properties, assets or securities to, (b) purchase or lease any
property, assets or securities from, (c) make any investments in, or (d) enter
into or suffer to exist any other transaction or series of related transactions
with, or for the benefit of, any Affiliate of Borrower unless: (i) such
transaction or series of transactions is on terms that are no less favorable to
Borrower or such Restricted Subsidiary than those that would be available in a
comparable arm's length transaction with an unrelated third party, (ii) with
respect to any one transaction or series of related transactions involving
aggregate payments in excess of $1,000,000, Borrower delivers an officer's
certificate to Agent certifying that such transaction or series of related
transactions complies with clause (i) above, and (iii) with respect to a
transaction or series of related transactions involving payments in excess of
$5,000,000, Borrower delivers an officer's certificate to Agent certifying that
(A) such transaction or series of related transactions complies with clause (i)
above and (B) such transaction or series of related transactions has been
approved by a majority of the Disinterested Directors of Borrower; provided,
however, that the foregoing restriction shall not apply to (u) any arrangements
in effect on the date hereof and described on the Disclosure Schedule, (v)
transactions between or among Borrower and the Restricted Subsidiaries, (w)
loans or advances to officers, directors and employees of Borrower or any
Restricted Subsidiary made in the ordinary course of business and consistent
with past practices of Borrower and its Restricted Subsidiaries in an aggregate
amount not to exceed $1,000,000 outstanding at any one time, (x) indemnities of
officers, directors and employees of Borrower or any Restricted Subsidiary
permitted by bylaw or statutory provisions, (y) the payment of reasonable and
customary regular fees to directors of Borrower or of any of its Restricted
Subsidiaries who are not employees of Borrower or any of its Affiliates, and
(z) Borrower's employee compensation and other benefit arrangements.

         Section 7.9.  Hedging and Certain Other Contracts; Amendments;
Multiemployer ERISA Plans.  Neither Borrower nor any Restricted Subsidiary will
enter into, or be or remain obligated on, any Hedging Contract, provided that
Borrower (but not any Restricted Subsidiary) may enter into





                                       40
<PAGE>   45
and be obligated on Hedging Contracts entered into with investment grade
counterparties to fix the interest rate on the Loans or the loans under the
Revolving Credit Agreement or to protect against declines against the U.S.
dollar of payments which will be paid to a Restricted Subsidiary in other
currencies under service contracts in place at the time in question.  Except as
expressly provided for in the Loan Documents, neither Borrower nor any
Restricted Subsidiary will, directly or indirectly, enter into, create, or
otherwise allow to exist any contract or other consensual restriction on the
ability of any Restricted Subsidiary to: (i) make Distributions to Borrower,
(ii) to repay Indebtedness or obligations owing by it to Borrower, or (iii) to
transfer any of its assets to Borrower.  No Related Person will amend or permit
any amendment to any contract or lease which releases, qualifies, limits, makes
contingent or otherwise detrimentally affects the rights and benefits of any
Bank Party under or acquired pursuant to any Security Documents.  No Related
Person will incur any obligation to contribute to any "multiemployer plan" as
defined in Section 4001 of ERISA.

         Section 7.10.  Public Notes.  Borrower will not amend the Indenture or
the Public Notes or allow any Subsidiaries of Borrower which have guarantied
the Public Notes to amend their guaranties.  Borrower will not prepay, redeem
or repurchase any of the Public Notes, provided that Borrower may do so using
net proceeds from future sales of its common stock or (if then permitted
hereunder) its preferred stock if Borrower has at the time of any such
prepayment, redemption or purchase made prepayments hereunder which have
reduced the aggregate principal payments due at the maturity hereof to
$12,000,000 or less.  Notwithstanding the foregoing provisions of this Section
7.10, Agent and Lenders hereby expressly consent to the exchange of
transfer-restricted Public Notes for Public Notes without such restrictions
(but otherwise on the same terms), as contemplated in the Offering Circular.
If Borrower or any Restricted Subsidiary at any time receives "Net Proceeds"
from any "Asset Sale", as such terms are defined in the Indenture, Borrower
will cause such "Net Proceeds" to be applied either to investments in
properties and capital assets (if permitted hereunder) or to prepayment of the
amounts outstanding hereunder, with such investments and prepayments being
timely made with the result that no "Excess Proceeds", as defined in the
Indenture, ever exist prior to the repayment in full of all amounts outstanding
hereunder or under the Revolving Credit Agreement.  If Borrower is ever
required to offer to repurchase any Public Notes as a result of any "Change of
Control", as such term is defined in the Indenture, Borrower will, prior to
making any such offer, repay the Notes in full and terminate this Agreement.

         Section 7.11.  Current Ratio.  The ratio of the Consolidated current
assets of Borrower and its Restricted Subsidiaries to their Consolidated
current liabilities will never be less than 1 to 1.

         Section 7.12.  EBITDA.  At the end of any Fiscal Quarter, the ratio of
(a) Borrower's and Restricted Subsidiaries' EBITDA to (b) required principal
and interest payments on the Obligations, the loans under the Revolving Credit
Agreement, the Public Notes and any other borrowed money for the four-Fiscal
Quarter period ending with such Fiscal Quarter will not be less than 1.25 to 1
for any such period ending prior to March 1, 1998 and not less than 1.40 to 1
for any such period ending on or after such date.  As used in this section,
"EBITDA" means, for any such four-Fiscal Quarter period, the sum of (1) the
Consolidated net income of Borrower and the Restricted Subsidiaries during such
period, plus (2) all interest paid or accrued during such period on the
Obligations, the loans under the Revolving Credit Agreement, the Public Notes
and any other borrowed money (including amortization of original issue discount
and the interest component of any deferred payment obligations and capital
lease obligations) which was deducted in determining such





                                       41
<PAGE>   46
Consolidated net income, plus (3) all income taxes which were deducted in
determining such Consolidated net income, plus (4) all depreciation,
amortization (including amortization of good will and debt issue costs) and
other non-cash charges (including any provision for the reduction in the
carrying value of assets recorded in accordance with GAAP) which were deducted
in determining such Consolidated net income, minus (5) all non-cash items of
income which were included in determining such Consolidated net income.

         Section 7.13.  Debt to Capital Ratio.  The quotient of Adjusted
Indebtedness divided by Total Capitalization (herein called the "Debt to
Capital Ratio") will never exceed (a) sixty-five percent (65%) at any time from
the date hereof through and including August 31, 1998, or (b) sixty percent
(60%) at any time on or after September 1, 1998.  As used in this section:

                 "Adjusted Indebtedness" means, at the time in question, all
         Indebtedness of Borrower and the Restricted Subsidiaries (after
         elimination of intercompany accounts between themselves), whether or
         not required by GAAP to be presented on a balance sheet, and

                 "Total Capitalization" means, at the time in question, the sum
         of (i) Adjusted Indebtedness at such time, plus (ii) the Consolidated
         shareholders' equity in Borrower and its Restricted Subsidiaries at
         such time;

provided that all loans to and other investments of any kind in Unrestricted
Subsidiaries shall be valued at zero.

constitutes an Event of Default under this Agreement:

                 (a)  Borrower or any Restricted Subsidiary fails to pay the
         principal component of any Obligation when due and payable, whether at

         or otherwise;

                 (b)  Borrower or any Restricted Subsidiary fails to pay any

         fixed installment or as a contingent or other payment becomes due and
         payable or as a result of acceleration or otherwise, within five days
         after the same becomes due;

                 (c)  Any "default" or "event of default" occurs under any Loan
         Document which defines either such term, and the same is not remedied
         within the applicable period of grace (if any) provided in such Loan
         Document;





                                       42
<PAGE>   47
                 (d)  Any Related Person fails to duly observe, perform or

         comply with any covenant, agreement, condition or provision of any
         Loan Document, and such failure remains unremedied for a period of
         thirty (30) days after notice of such failure is given by Agent to
         Borrower;

                 (f)  Any representation or warranty previously, presently or
         hereafter made in writing by or on behalf of any Related Person in
         connection with any Loan Document shall prove to have been false or
         incorrect in any material respect on any date on or as of which made,
         or any Loan Document at any time ceases to be valid, binding and
         enforceable as warranted in Section 5.5 for any reason other than its
         release or subordination by Agent or Collateral Agent;

                 (g)  Borrower or any Restricted Subsidiary (i) fails to pay
         any portion, when such portion is due, of any of its Indebtedness in
         excess of $7,500,000, or (ii) any event specified in any note,
         agreement, indenture or other document evidencing or relating to any
         such Indebtedness shall occur if the effect of such event is to cause,
         or (with the giving of any notice of the lapse of time or both) to
         permit the holder or holders of such Indebtedness (or a trustee or
         agent on behalf of such holder or holders) to cause, such Indebtedness
         to become due prior to its stated maturity;

         amended) in excess of $1,000,000 exists with respect to any ERISA
         Plan, whether or not waived by the Secretary of the Treasury or his
         delegate, or (ii) any Termination Event occurs with respect to any
         ERISA Plan and the then current value of such ERISA Plan's benefit
         liabilities exceeds the then current value of such ERISA Plan's assets
         available for the payment of such benefit liabilities by more than
         $1,000,000 (or in the case of a Termination Event involving the
         withdrawal of a substantial employer, the withdrawing employer's
         proportionate share of such excess exceeds such amount);

                 (i)  Any Change of Control occurs; and

                 (j)  Borrower or any Restricted Subsidiary:

                 decree or order for relief by a court of competent
                 jurisdiction in an involuntary proceeding commenced under any
                 applicable bankruptcy, insolvency or other similar Law of any
                 jurisdiction now or hereafter in effect, including the federal
                 Bankruptcy Code, as from time to time amended, or has any such

<PAGE>   48
                 from time to time amended; or applies for or consents to the

                 substantial part of its assets (or of any Collateral worth
                 more than $7,500,000 in the aggregate) in a proceeding brought
                 against or initiated by it, and such appointment or taking
                 possession is neither made ineffective nor discharged within
                 ninety days after the making thereof, or such appointment or
                 taking possession is at any time consented to, requested by,

                 similar process to be issued by any court against all or any
                 substantial part of its assets or any part of the Collateral,
                 and such writ or warrant of attachment or any similar process
                 is not stayed or released within sixty days after the entry or
                 levy thereof or after any stay is vacated or set aside.

Upon the occurrence of an Event of Default described in subsection (j)(i),
(j)(ii) or (j)(iii) of this section with respect to Borrower, all of the
Obligations shall thereupon be immediately due and payable, without demand,
presentment, notice of demand or of dishonor and nonpayment, protest, notice of
protest, notice of intention to accelerate, declaration or notice of
acceleration, or any other notice or declaration of any kind, all of which are
hereby expressly waived by Borrower and each Related Person who at any time
ratifies or approves this Agreement.  Upon any such acceleration, any
obligation of any Lender to make any further Loans shall be permanently
terminated.  During the continuance of any other Event of Default, Agent at any
time and from time to time shall, upon written instructions from Majority
Lenders, without notice to Borrower or any other Related Person, do either or
both of the following: (1) terminate any obligation of Lenders to make Loans
hereunder, and (2) declare any or all of the Obligations immediately due and
payable, and all such Obligations shall thereupon be immediately due and

nonpayment, protest, notice of protest, notice of intention to accelerate,
declaration or notice of acceleration, or any other notice or declaration of
any kind, all of which are hereby expressly waived by Borrower and each Related
Person who at any time ratifies or approves this Agreement.

         Section 8.2.  Bank Accounts; Offset.  To secure the repayment of the
Obligations, Borrower hereby grants to each Bank Party a security interest, a
lien, and a right of offset, each of which shall





                                       44
<PAGE>   49
be in addition to all other interests, liens, and rights of such Bank Party at
common law, under the Loan Documents, or otherwise, and each of which shall be
upon and against (a) any and all moneys, securities or other property (and the
proceeds therefrom) of Borrower now or hereafter held or received by or in
transit to such Bank Party from or for the account of Borrower, whether for
safekeeping, custody, pledge, transmission, collection or otherwise, (b) any
and all deposits (general or special, time or demand, provisional or final) of
Borrower with such Bank Party, and (c) any other credits and claims of Borrower
at any time existing against such Bank Party, including claims under
certificates of deposit.  At any time and from time to time after the
occurrence of any Event of Default, each Bank Party is hereby authorized to (i)
foreclose upon any of the foregoing items subject to such security interest in
order to collect all Obligations then due and payable, and (ii) offset any of
the foregoing items against the Obligations then due and payable (in either
case without notice to Borrower).  The remedies of foreclosure and offset are
separate and cumulative, and either may be exercised independently of the other
without regard to procedures or restrictions applicable to the other.


ARTICLE IX - Agent

         Section 9.1.  Appointment and Authority.  Each Bank Party hereby
irrevocably authorizes Agent, and Agent hereby undertakes, to receive payments
of principal, interest and other amounts due hereunder as specified herein and
to take all other actions and to exercise such powers under the Loan Documents
as are specifically delegated to Agent by the terms hereof or thereof, together
with all other powers reasonably incidental thereto.  The relationship of Agent
to the other Bank Parties is only that of one commercial lender acting as
administrative agent for others, and nothing in the Loan Documents shall be
construed to constitute Agent a trustee or other fiduciary for any holder of
any of the Notes or of any participation therein nor to impose on Agent duties
and obligations other than those expressly provided for in the Loan Documents.
With respect to any matters not expressly provided for in the Loan Documents
and any matters which the Loan Documents place within the discretion of Agent,
Agent shall not be required to exercise any discretion or take any action, and
it may request instructions from Lenders with respect to any such matter, in
which case it shall be required to act or to refrain from acting (and shall be
fully protected and free from liability to all Lenders in so acting or
refraining from acting) upon the instructions of Lenders (including itself)
whose aggregate Percentage Shares exceed fifty percent (50%), provided,
however, that Agent shall not be required to take any action which exposes it
to a risk of personal liability that it considers unreasonable or which is
contrary to the Loan Documents or to applicable Law.  Upon receipt by Agent
from Borrower of any communication calling for action on the part of Lenders or
upon notice from any other Bank Party to Agent of any Default or Event of
Default, Agent shall promptly notify each other Bank Party thereof.

         Section 9.2.  Exculpation, Agent's Reliance, Etc.  NEITHER AGENT NOR
ANY OF ITS DIRECTORS, OFFICERS, AGENTS, OR EMPLOYEES SHALL BE LIABLE FOR ANY
ACTION TAKEN OR OMITTED TO BE TAKEN BY ANY OF THEM UNDER OR IN CONNECTION WITH
THE LOAN DOCUMENTS, INCLUDING THEIR NEGLIGENCE OF ANY KIND, EXCEPT THAT EACH
SHALL BE LIABLE FOR ITS OWN GROSS NEGLIGENCE OR WILLFUL MISCONDUCT.  Without
limiting the generality of the foregoing, Agent (a) may treat the payee of any
Note as the holder thereof until Agent receives written notice of the
assignment or transfer thereof in accordance 





                                       45
<PAGE>   50

with this Agreement, signed by such payee and in form satisfactory to Agent; (b)
may consult with legal counsel (including counsel for Borrower), independent
public accountants and other experts selected by it and shall not be liable for
any action taken or omitted to be taken in good faith by it in accordance with
the advice of such counsel, accountants or experts; (c) makes no warranty or
representation to any other Bank Party and shall not be responsible to any other
Bank Party for any statements, warranties or representations made in or in
connection with the Loan Documents; (d) shall not have any duty to ascertain or
to inquire as to the performance or observance of any of the terms, covenants or
conditions of the Loan Documents on the part of any Related Person or to inspect
the property (including the books and records) of any Related Person; (e) shall
not be responsible to any other Bank Party for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of any Loan Document
or any instrument or document furnished in connection therewith; (f) may rely
upon the representations and warranties of the Related Persons and the Lenders
in exercising its powers hereunder; and (g) shall incur no liability under or in
respect of the Loan Documents by acting upon any notice, consent, certificate or
other instrument or writing (including any telecopy, telegram, cable or telex)
believed by it to be genuine and signed or sent by the proper Person or Persons.

         Section 9.3.  Credit Decisions.  Each Bank Party acknowledges that it
has, independently and without reliance upon any other Bank Party, made its own
analysis of Borrower and the transactions contemplated hereby and its own
independent decision to enter into this Agreement and the other Loan Documents.
Each Bank Party also acknowledges that it will, independently and without
reliance upon any other Bank Party and based on such documents and information
as it shall deem appropriate at the time, continue to make its own credit
decisions in taking or not taking action under the Loan Documents.

         Section 9.4.  Indemnification.  Each Lender agrees to indemnify Agent
and Collateral Agent (to the extent not reimbursed by Borrower within ten (10)
days after demand) from and against such Lender's Percentage Share of any and
all liabilities, obligations, claims, losses, damages, penalties, fines,
actions, judgments, suits, settlements, costs, expenses or disbursements
(including reasonable fees of attorneys, accountants, experts and advisors) of
any kind or nature whatsoever (in this section collectively called "liabilities
and costs") which to any extent (in whole or in part) may be imposed on,
incurred by, or asserted against Agent or Collateral Agent growing out of,
resulting from or in any other way associated with any of the Collateral, the
Loan Documents and the transactions and events (including the enforcement
thereof) at any time associated therewith or contemplated therein (including
any violation or noncompliance with any Environmental Laws by any Person or any
liabilities or duties of any Person with respect to Hazardous Materials found
in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY
CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY AGENT OR COLLATERAL AGENT,

provided only that no Lender shall be obligated under this section to indemnify
Agent or Collateral Agent for that portion, if any, of any liabilities and
costs which is proximately caused by such indemnitee's own individual gross
negligence or willful misconduct, as determined in a final





                                       46
<PAGE>   51
judgment.  Cumulative of the foregoing, each Lender agrees to reimburse Agent
and Collateral Agent promptly upon demand for such Lender's Percentage Share of
any costs and expenses to be paid to Agent or Collateral Agent by Borrower
under Section 10.4(i) to the extent that Agent or Collateral Agent is not
timely reimbursed for such expenses by Borrower as provided in such section.
As used in this section the terms "Agent" and "Collateral Agent" shall refer
not only to the Persons designated as such in Section 1.1 but also to each
director, officer, agent, employee, representative and Affiliate of such
Person.

         Section 9.5.  Rights as Lender.  In its capacity as a Lender, each
Person serving as Agent or Collateral Agent shall have the same rights and
obligations as any Lender and may exercise such rights as though it were not
Agent or Collateral Agent, and each such Person may accept deposits from, lend
money to, act as Trustee under indentures of, and generally engage in any kind
of business with any of the Related Persons or their Affiliates, all as if it
were not Agent or Collateral Agent hereunder and without any duty to account
therefor to any other Lender.

         Section 9.6.  Sharing of Set-Offs and Other Payments.  Each Bank Party
agrees that if it shall, whether through the exercise of rights under Security
Documents or rights of banker's lien, set off, or counterclaim against Borrower
or otherwise, obtain payment of a portion of the aggregate Obligations owed to
it which, taking into account all distributions made by Agent under Section
3.1, causes such Bank Party to have received more than it would have received
had such payment been received by Agent and distributed pursuant to Section
3.1, then (a) it shall be deemed to have simultaneously purchased and shall be
obligated to purchase interests in the Obligations as necessary to cause all
Bank Parties to share all payments as provided for in Section 3.1, and (b) such
other adjustments shall be made from time to time as shall be equitable to
ensure that all Bank Parties share all payments of Obligations as provided in
Section 3.1; provided, however, that nothing herein contained shall in any way
affect the right of any Bank Party to obtain payment (whether by exercise of
rights of banker's lien, set-off or counterclaim or otherwise) of Liabilities
other than the Obligations.  Borrower expressly consents to the foregoing
arrangements and agrees that any holder of any such interest or other
participation in the Obligations, whether or not acquired pursuant to the
foregoing arrangements, may to the fullest extent permitted by Law exercise any
and all rights of banker's lien, set-off, or counterclaim as fully as if such
holder were a holder of the Obligations in the amount of such interest or other
participation.  If all or any part of any funds transferred pursuant to this
section is thereafter recovered from the seller under this section which
received the same, the purchase provided for in this section shall be deemed to
have been rescinded to the extent of such recovery, together with interest, if
any, if interest is required pursuant to court order to be paid on account of
the possession of such funds prior to such recovery.

         Section 9.7.  Investments.  Whenever Agent or Collateral Agent in good
faith determines that it is uncertain about how to distribute to Lenders any
funds which it has received, or whenever Agent or Collateral Agent in good
faith determines that there is any dispute among Lenders about how such funds
should be distributed, Agent or Collateral Agent may choose to defer
distribution of the funds which are the subject of such uncertainty or dispute.
If Agent or Collateral Agent in good faith believes that the uncertainty or
dispute will not be promptly resolved, or if Agent is otherwise required to
invest funds pending distribution to Lenders, Agent or Collateral Agent shall
invest such funds pending distribution; all interest on any such investment
shall be distributed upon the distribution of such investment and in the same
proportion and to the same Persons as such





                                       47
<PAGE>   52
investment.  All moneys received by Agent or Collateral Agent for distribution
to Lenders (other than to the Person who is Agent or Collateral Agent in its
separate capacity as a Lender) shall be held by Agent or Collateral Agent
pending such distribution solely as Agent or Collateral Agent for such Lenders,
and Agent or Collateral Agent shall have no equitable title to any portion
thereof.

         Section 9.8.  Benefit of Article IX.  The provisions of this Article
(other than the following Section 9.9) are intended solely for the benefit of
the Bank Parties, and no Related Person shall be entitled to rely on any such
provision or assert any such provision in a claim or defense against any Bank
Party.  The Bank Parties may waive or amend such provisions as they desire
without any notice to or consent of Borrower or any other Related Person.

         Section 9.9.  Resignation.  Agent may resign at any time by giving
written notice thereof to Lenders and Borrower.  Each such notice shall set
forth the date of such resignation.  Upon any such resignation Borrower may,
with the written concurrence of Lenders whose aggregate Percentage Shares
exceed fifty percent (50%), designate a successor Agent.  If within fifteen
days after the date of such resignation Borrower makes no such designation or
such written concurrence is not given, Majority Lenders shall have the right to
appoint a successor Agent.  A successor must be appointed for any retiring
Agent, and such Agent's resignation shall become effective when such successor
accepts such appointment.  If, within thirty days after the date of the
retiring Agent's resignation, no successor Agent has been appointed and has
accepted such appointment, then the retiring Agent may appoint a successor
Agent, which shall be a commercial bank organized or licensed to conduct a
banking or trust business under the Laws of the United States of America or of
any state thereof.  Upon the acceptance of any appointment as Agent hereunder
by a successor Agent, the retiring Agent shall be discharged from its duties
and obligations under this Agreement and the other Loan Documents.  After any
retiring Agent's resignation hereunder the provisions of this Article IX shall
continue to inure to its benefit as to any actions taken or omitted to be taken
by it while it was Agent under the Loan Documents.


ARTICLE X - Miscellaneous

         Section 10.1.  Waivers and Amendments; Acknowledgements.

         (a)  Waivers and Amendments.  No failure or delay (whether by course
of conduct or otherwise) by any Bank Party in exercising any right, power or
remedy which such Bank Party may have under any of the Loan Documents shall
operate as a waiver thereof or of any other right, power or remedy, nor shall
any single or partial exercise by any Bank Party of any such right, power or
remedy preclude any other or further exercise thereof or of any other right,
power or remedy.  No waiver of any provision of any Loan Document and no
consent to any departure therefrom shall ever be effective unless it is in
writing and signed as provided below in this section, and then such waiver or
consent shall be effective only in the specific instances and for the purposes
for which given and to the extent specified in such writing.  No notice to or
demand on any Related Person shall in any case of itself entitle any Related
Person to any other or further notice or demand in similar or other
circumstances.  No waiver, consent, release, modification or amendment of or
supplement to this Agreement or the other Loan Documents shall be valid or
effective against any party hereto unless 





                                       48
<PAGE>   53
the same is in writing and signed by (i) if such party is Borrower, by
Borrower, (ii) if such party is Agent or Collateral Agent, by such party, and
(iii) if such party is a Lender, by such Lender or by Agent on behalf of
Lenders with the written consent of Majority Lenders.  Notwithstanding the
foregoing or anything to the contrary herein, Agent shall not, without the
prior consent of each individual Lender, execute and deliver on behalf of such
Lender any waiver or amendment which would:  (1) waive any of the conditions
specified in Article IV (provided that Agent may in its discretion withdraw any
request it has made under Section 4.2(e)), (2) increase the Maximum Loan Amount
or the Percentage Share of such Lender, (3) reduce any fees payable hereunder
to such Lender, or the principal of, or interest on, such Lender's Note, (4)
postpone any date fixed for any payment of any such fees, principal, or
interest, (5) amend the definition herein of "Majority Lenders" or otherwise
change the aggregate amount of Percentage Shares which is required for Agent,
Lenders or any of them to take any particular action under the Loan Documents.
The consent of each Lender to the termination of the Loan Documents is
contained in Section 10.8.

         (b)  Acknowledgements and Admissions.  Borrower hereby represents,
warrants, acknowledges and admits that (i) it has been advised by counsel in
the negotiation, execution and delivery of the Loan Documents to which it is a
party, (ii) it has made an independent decision to enter into this Agreement
and the other Loan Documents to which it is a party, without reliance on any
representation, warranty, covenant or undertaking by Agent or any Lender,
whether written, oral or implicit, other than as expressly set out in this
Agreement or in another Loan Document delivered on or after the date hereof,
(iii) there are no representations, warranties, covenants, undertakings or
agreements by any Bank Party as to the Loan Documents except as expressly set
out in this Agreement or in another Loan Document delivered on or after the
date hereof, (iv) no Bank Party has any fiduciary obligation toward Borrower
with respect to any Loan Document or the transactions contemplated thereby, (v)
the relationship pursuant to the Loan Documents between Borrower, on one hand,
and each Bank Party, on the other hand, is and shall be solely that of debtor
and creditor (or, where appropriate, letter of credit applicant and issuer)
respectively, (vi) no partnership or joint venture exists with respect to the
Loan Documents between Borrower and any Bank Party, (vii) Agent and Collateral
Agent are not agents of Borrower, but Agent and Collateral Agent for Lenders,
(viii) should an Event of Default or Default occur or exist each Bank Party
will determine in its sole discretion and for its own reasons what remedies and
actions it will or will not exercise or take at that time, (ix) without
limiting any of the foregoing, Borrower is not relying upon any representation
or covenant by any Bank Party, or any representative thereof, and no such
representation or covenant has been made, that any Bank Party will, at the time
of an Event of Default or Default, or at any other time, waive, negotiate,
discuss, or take or refrain from taking any action permitted under the Loan
Documents with respect to any such Event of Default or Default or any other
provision of the Loan Documents, and (x) each Bank Party has relied upon the
truthfulness of the acknowledgements in this section in deciding to execute and
deliver this Agreement and to become obligated hereby.

         (c)  Final Agreement.  This Agreement and the other Loan Documents set
forth the entire understanding between the parties hereto with respect to the
transactions contemplated herein and therein and supersede all prior
discussions and understandings with respect to the subject matter hereof and
thereof.





                                       49

         THIS WRITTEN AGREEMENT AND THE OTHER LOAN DOCUMENTS REPRESENT THE
FINAL AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF
PRIOR, CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES.

         THERE ARE NO UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.

         Section 10.2.  Survival of Agreements; Cumulative Nature.  All of the
Related Persons' various representations, warranties, covenants and agreements
in the Loan Documents shall survive the execution and delivery of this
Agreement and the other Loan Documents and the performance hereof and thereof,
including the making or granting of the Loans and the delivery of the Notes and
the other Loan Documents, and shall further survive until all of the
Obligations are paid in full to each Bank Party and each Bank Party's
obligations to Borrower are terminated.  All statements and agreements
contained in any certificate or other instrument delivered by any Related
Person to any Bank Party under any Loan Document shall be deemed
representations and warranties by Borrower or agreements and covenants of
Borrower under this Agreement.  The representations, warranties, indemnities,
and covenants made by the Related Persons in the Loan Documents, and the
rights, powers, and privileges granted to each Bank Party in the Loan
Documents, are cumulative, and, except for expressly specified waivers and
consents, no Loan Document shall be construed in the context of another to
diminish, nullify, or otherwise reduce the benefit to any Bank Party of any
such representation, warranty, indemnity, covenant, right, power or privilege.
In particular and without limitation, no exception set out in this Agreement to
any representation, warranty, indemnity, or covenant herein contained shall
apply to any similar representation, warranty, indemnity, or covenant contained
in any other Loan Document, and each such similar representation, warranty,
indemnity, or covenant shall be subject only to those exceptions which are
expressly made applicable to it by the terms of the various Loan Documents.

         Section 10.3.  Notices.  All notices, requests, consents, demands and
other communications required or permitted under any Loan Document shall be in
writing, unless otherwise specifically provided in such Loan Document (provided
that Agent and Collateral Agent may give telephonic notices to the other Bank
Parties), and shall be deemed sufficiently given or furnished if delivered by
personal delivery, by telecopy, by delivery service with proof of delivery, or
by registered or certified United States mail, postage prepaid, to Borrower and
the Related Persons at the address of Borrower specified on the signature pages
hereto and to each Bank Party at its address specified on the signature pages
hereto (unless changed by similar notice in writing given by the particular
Person whose address is to be changed).  Any such notice or communication shall
be deemed to have been given (a) in the case of personal delivery or delivery
service, as of the date of first attempted delivery during normal business
hours at the address provided herein, (b) in the case of telecopy, upon
receipt, or (c) in the case of registered or certified United States mail,
three days after deposit in the mail; provided, however, that no Borrowing
Notice shall become effective until actually received by Agent.

         Section 10.4.  Payment of Expenses; Indemnity.

         (a)  Payment of Expenses.  Whether or not the transactions
contemplated by this Agreement are consummated, Borrower will promptly (and in
any event, within 30 days after any invoice or other statement or notice) pay:





                                       50
<PAGE>   55
                 (i) all transfer, stamp, mortgage, documentary or other
         similar taxes, assessments or charges levied by any governmental or
         revenue authority in respect of this Agreement or any of the other
         Loan Documents or any other document referred to herein or therein,

                 (ii) all reasonable costs and expenses incurred by or on
         behalf of Agent or Collateral Agent (including attorneys' fees,
         consultants' fees and engineering fees, travel costs, and
         miscellaneous expenses) in connection with (1) the negotiation,
         preparation, execution and delivery of the Loan Documents, and all
         consents, waivers or other documents or instruments relating thereto,
         and all due diligence related thereto, (2) the filing, recording,
         refiling and re-recording of any Loan Documents and any other
         documents or instruments or further assurances required to be filed or
         recorded or refiled or re-recorded by the terms of any Loan Document,
         (3) the borrowings hereunder and other action reasonably required in
         the course of administration hereof, (4) monitoring or confirming (or
         preparation or negotiation of any document related to) Borrower's
         compliance with any covenants or conditions contained in this
         Agreement or in any Loan Document, and


                 (iii) all reasonable costs and expenses incurred by or on
         behalf of any Bank Party (including attorneys' fees, consultants' fees
         and accounting fees) in connection with the defense or enforcement of
         any of the Loan Documents (including this section) or the defense of
         any Bank Party's exercise of its rights thereunder.

         (b)  Indemnity.  Borrower agrees to indemnify each Bank Party, upon
demand, from and against any and all liabilities, obligations, claims, losses,
damages, penalties, fines, actions, judgments, suits, settlements, costs,
expenses or disbursements (including reasonable fees of attorneys, accountants,
experts and advisors) of any kind or nature whatsoever (in this section
collectively called "liabilities and costs") which to any extent (in whole or
in part) may be imposed on, incurred by, or asserted against such Bank Party
growing out of, resulting from or in any other way associated with any of the
Acquisitions, the Collateral, the Loan Documents and the transactions and
events (including the enforcement or defense thereof) at any time associated
therewith or contemplated therein (including any violation or noncompliance
with any Environmental Laws by any Related Person or any liabilities or duties
of any Related Person or any Bank Party with respect to Hazardous Materials
found in or released into the environment).

THE FOREGOING INDEMNIFICATION SHALL APPLY WHETHER OR NOT SUCH LIABILITIES AND
COSTS ARE IN ANY WAY OR TO ANY EXTENT OWED, IN WHOLE OR IN PART, UNDER ANY
CLAIM OR THEORY OF STRICT LIABILITY, OR ARE CAUSED, IN WHOLE OR IN PART, BY ANY
NEGLIGENT ACT OR OMISSION OF ANY KIND BY ANY BANK PARTY,

provided only that no Bank Party shall be entitled under this section to
receive indemnification for that portion, if any, of any liabilities and costs
which is proximately caused by its own individual gross negligence or willful
misconduct, as determined in a final judgment.  As used in this section the
term "Bank Parties"  shall refer not only to the Persons designated as such in
Section 1.1 but also to each director, officer, agent, employee, representative
and Affiliate of such Person.

         Section 10.5.  Parties in Interest; Assignments.
                                                         
         (a)  All grants, covenants and agreements contained in the Loan
Documents shall bind and inure to the benefit of the parties thereto and their
respective successors and assigns; provided, however, that no Related Person
may assign or transfer any of its rights or delegate any of its duties or
obligations under any Loan Document without the prior consent of Majority
Lenders.  Neither Borrower nor any Affiliates of Borrower shall directly or
indirectly purchase or otherwise retire any Obligations owed to any Lender nor
will any Lender accept any offer to do so, unless each Lender shall have
received substantially the same offer with respect to the same Percentage Share
of the Obligations owed to it.  If Borrower or any Affiliate of Borrower at any
time purchases some but less than all of the Obligations owed to all Bank
Parties, such purchaser shall not be entitled to any rights of a Bank Party
under the Loan Documents unless and until Borrower or its Affiliates have
purchased all of the Obligations.

         (b)  No Lender shall sell any participation interest in its commitment
hereunder or any of its rights under its Loans or under the Loan Documents to
any Person other than an Eligible Transferee, and then only if the agreement
between such Lender and such participant at all times provides: (i) that such
participation exists only as a result of the agreement between such participant
and such Lender and that such transfer does not give such participant any right
to vote as a Lender or any other direct claims or rights against any Person
other than such Lender, (ii) that such participant is not entitled to payment
from any Related Person under Sections 3.2 through 3.6 of amounts in excess of
those payable to such Lender under such sections (determined without regard to
the sale of such participation), and (iii) unless such participant is an
Affiliate of such Lender, that such participant shall not be entitled to
require such Lender to take any action under any Loan Document or to obtain the
consent of such participant prior to taking any action under any Loan Document,
except for actions which would require the consent of all Lenders under the
next-to-last sentence of subsection (a) of Section 10.1.  No Lender selling
such a participation shall, as between the other parties hereto and such
Lender, be relieved of any of its obligations hereunder as a result of the sale
of such participation.  Each Lender which sells any such participation to any
Person (other than an Affiliate of such Lender) shall give prompt notice
thereof to Agent and Borrower.

         (c)  Except for sales of participations under the immediately
preceding subsection (b), no Lender shall make any assignment or transfer of
any kind of its commitments or any of its rights under its Loans or under the
Loan Documents, except for assignments to an Eligible Transferee, and then only
if such assignment is made in accordance with the following requirements:

                 (i)  Each such assignment shall apply to all Obligations owing
         to the assignor Lender hereunder and to the unused portion of the
         assignor Lender's commitments, so that after such assignment is made
         the assignor Lender shall have a fixed (and not a varying) Percentage
         Share in its Loans and Note and be committed to make that Percentage
         Share of all future Loans, the assignee shall have a fixed Percentage
         Share in such Loans and Note and be committed to make that Percentage
         Share of all future Loans, and the Percentage Share of the Maximum
         Loan Amount of both the assignor and assignee shall equal or exceed
         $5,000,000.

                 (ii)  The parties to each such assignment shall execute and
         deliver to Agent, for its acceptance and recording in the "Register"
         (as defined below in this section), an Assignment and Acceptance in
         the form of Exhibit E, appropriately completed, together with the Note





                                       52
<PAGE>   57
         subject to such assignment and a processing fee payable to Agent of
         $2,500.  Upon such execution, delivery, and payment and upon the
         satisfaction of the conditions set out in such Assignment and
         Acceptance, then (i) Borrower shall issue new Notes to such assignor
         and assignee upon return of the old Notes to Borrower, and (ii) as of
         the "Settlement Date" specified in such Assignment and Acceptance the
         assignee thereunder shall be a party hereto and a Lender hereunder and
         Agent shall thereupon deliver to Borrower and each Lender a schedule
         showing the revised Percentage Shares of such assignor Lender and such
         assignee Lender and the Percentage Shares of all other Lenders.

                 (iii)  Each assignee Lender which is not a United States
         person (as such term is defined in Section 7701(a)(30) of the Internal
         Revenue Code of 1986, as amended) for Federal income tax purposes,
         shall (to the extent it has not already done so) provide Agent and
         Borrower with the "Prescribed Forms" referred to in Section 3.6(d).

         (d)  Nothing contained in this section shall prevent or prohibit any
Lender from assigning or pledging all or any portion of its Loans and Note to
any Federal Reserve Bank as collateral security pursuant to Regulation A of the
Board of Governors of the Federal Reserve System and any Operating Circular
issued by such Federal Reserve Bank; provided that no such assignment or pledge
shall relieve such Lender from its obligations hereunder.

         (e)  By executing and delivering an Assignment and Acceptance, each
assignee Lender thereunder will be confirming to and agreeing with Borrower,
Agents and each other Lender hereunder that such assignee understands and
agrees to the terms hereof, including Article IX hereof.

         (f)  Agent shall maintain a copy of each Assignment and Acceptance and
a register for the recordation of the names and addresses of Lenders and the
Percentage Shares of, and principal amount of the Loans owing to, each Lender
from time to time (in this section called the "Register").  The entries in the
Register shall be conclusive, in the absence of manifest error, and Borrower
and each Bank Party may treat each Person whose name is recorded in the
Register as a Lender hereunder for all purposes.  The Register shall be
available for inspection by Borrower or any Bank Party at any reasonable time
and from time to time upon reasonable prior notice.

         Section 10.6.  Confidentiality.  Each of Agent and Lenders agrees that
it will take all reasonable steps to keep confidential any proprietary
information given to it by any Related Person, provided, however, that this
restriction shall not apply to information which (i) has at the time in
question entered the public domain, (ii) is required to be disclosed by Law
(whether valid or invalid) of any court or governmental agency or authority,
(iii) is disclosed to Agent's or any Lender's Affiliates, auditors, attorneys,
or agents (provided such Persons are obligated to hold such information in
confidence on the terms provided in this section), (iv) is furnished to any
other Lender or to any purchaser or prospective purchaser of participations or
other interests in any Loan or Loan Document (provided each such purchaser or
prospective purchaser first agrees to hold such information in confidence on
the terms provided in this section), or (v) is disclosed in the course of
enforcing its rights and remedies during the existence of an Event of Default.

         Section 10.7.  Limitation on Interest.  The Bank Parties, the Related
Persons, and all other parties to the Loan Documents intend to contract in
strict compliance with applicable usury Law





                                       53
<PAGE>   58
from time to time in effect.  In furtherance thereof such persons stipulate and
agree that none of the terms and provisions contained in the Loan Documents
shall ever be construed to provide for interest in excess of the maximum amount
of interest permitted to be charged by applicable Law from time to time in
effect.  Neither any Related Person nor any present or future guarantors,
endorsers, or other Persons hereafter becoming liable for payment of any
Obligation shall ever be liable for unearned interest thereon or shall ever be
required to pay interest thereon in excess of the maximum amount that may be
lawfully charged under applicable Law from time to time in effect, and the
provisions of this section shall control over all other provisions of the Loan
Documents which may be in conflict or apparent conflict herewith.  If,
notwithstanding the foregoing, any amount constituting interest is nonetheless
charged or collected in excess of the maximum amount of interest permitted to
be charged by applicable Law from time to time in effect, then such excess
interest shall, at the option of the payee thereof, be credited on the amount
of the Obligations owed to such payee or refunded by such payee to the payor
thereof.

         Section 10.8.  Termination; Limited Survival.  In its sole and
absolute discretion Borrower may at any time that no Obligations are owing
hereunder elect in a written notice delivered to Agent to terminate this
Agreement.  Upon receipt by Agent of such a notice, if no Obligations are then
owing this Agreement and all other Loan Documents shall thereupon be terminated
(other than any Loan Documents hereunder which are also "Loan Documents" at
such time under the Revolving Credit Agreement) and the parties thereto shall
thereupon be released from all prospective obligations hereunder or thereunder.
Notwithstanding the foregoing or anything herein to the contrary, any waivers
or admissions made by any Related Person in any Loan Document, any Obligations
under Article III, and any obligations which any Person may have to indemnify
or compensate any Bank Party shall survive any termination of this Agreement or
any other Loan Document.  At the request and expense of Borrower, Agent shall
prepare and execute all necessary instruments to reflect and effect such
termination of the Loan Documents.  Agent is hereby authorized to execute all
such instruments on behalf of all Lenders, without the joinder of or further
action by any Lender.

         Section 10.9.  Severability.  If any term or provision of any Loan
Document shall be determined to be illegal or unenforceable all other terms and
provisions of the Loan Documents shall nevertheless remain effective and shall
be enforced to the fullest extent permitted by applicable Law.

         Section 10.10.  Counterparts.  This Agreement may be separately
executed in any number of counterparts and by different parties hereto in
separate counterparts, each of which when so executed shall be deemed to
constitute one and the same Agreement.

         Section 10.11.  GOVERNING LAW; SUBMISSION TO PROCESS.  EXCEPT TO THE
EXTENT THAT THE LAW OF ANOTHER JURISDICTION IS EXPRESSLY ELECTED IN A LOAN
DOCUMENT, THE LOAN DOCUMENTS SHALL BE DEEMED CONTRACTS AND INSTRUMENTS MADE
UNDER THE LAWS OF THE STATE OF NEW YORK AND SHALL BE CONSTRUED AND ENFORCED IN
ACCORDANCE WITH AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK AND THE LAWS
OF THE UNITED STATES OF AMERICA, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF
LAW.  BORROWER HEREBY AGREES THAT ANY LEGAL ACTION OR PROCEEDING AGAINST
BORROWER OR ITS SUBSIDIARIES WITH RESPECT TO THIS AGREEMENT, THE NOTES OR ANY
OF THE LOAN DOCUMENTS MAY BE BROUGHT IN THE COURTS OF THE STATE OF NEW YORK OR
OF THE UNITED





                                       54

STATES OF AMERICA FOR THE SOUTHERN DISTRICT OF NEW YORK, AS AGENT AND MAJORITY
LENDERS MAY ELECT, AND, BY EXECUTION AND DELIVERY HEREOF, BORROWER ACCEPTS AND
CONSENTS FOR ITSELF AND IN RESPECT TO ITS PROPERTY, GENERALLY AND
