         SECTION 2 AMOUNTS AND TERMS OF OBLIGATIONS


         2.1 Revolving Loans.

             (a) Prior to the Termination Date and so long as no Default has
occurred, the Bank agrees on the terms and conditions set forth in this
Agreement to extend to the Company Revolving Loans from time to time in amounts
not to exceed the Revolving Loan Commitment. Subject to the terms of this
Agreement, the Company may borrow, repay (in whole or in part) and reborrow the
Revolving Loans prior to the Termination Date. The Revolving Loans made by the
Bank shall be evidenced by the Revolving Credit Note.


<PAGE>

             (b) From the date of the first Revolving Loan and until all
Revolving Loans are paid in full, the Company shall pay all accrued and unpaid
interest on the Revolving Loans on the first day of each month. Prior to an
Event of Default, interest shall accrue and be computed on the aggregate unpaid
principal amount from time to time outstanding under the Revolving Credit Note
as determined in the Revolving Credit Note. All outstanding unpaid principal and
accrued interest on the Revolving Loans shall be due and payable on the
Termination Date for the Revolving Loans. The Company shall pay to the Bank such
other charges, costs, expenses or premiums as the Bank may incur pursuant to the
Revolving Credit Note.

             (c) The Company may obtain Revolving Loans by making a request
therefor to the Bank, orally or in writing. Such request shall specify a
Business Day prior to the Termination Date on which such Revolving Loans are to
be made (the "Borrowing Date"), shall be received by the Bank by 12:00 Noon
(Milwaukee time) one Business Day before the Borrowing Date and shall specify
the amount of the Revolving Loans requested and the requested Loan Period;
provided, however, that within three days after any oral request for a Revolving
Loan, the Bank shall receive from the Company a written confirmation in form
acceptable to the Bank confirming the Company's Revolving Loan request, and the
Bank's obligation to make further Revolving Loans hereunder shall be suspended
until such confirmation has been received by the Bank. In the event of any
inconsistency between the telephonic notice and the written confirmation
thereof, the telephonic notice shall control. The Company shall be obligated to
repay all Revolving Loans notwithstanding the failure of the Bank to receive
written confirmation, and notwithstanding the fact that the person requesting
the Revolving Loan was not in fact authorized to do so. No Revolving Loan
request shall be modified, altered or amended without the prior written consent
of the Bank. Each Revolving Loan shall be in a minimum aggregate amount of
$100,000 or an integral multiple thereof. Upon fulfillment of the conditions
specified in Section 4.2, the Bank shall promptly deposit the amount of such
Revolving Loan in the general deposit account of the Company maintained at the
Bank.

             (d) The Company may, upon one Business Day's prior written notice
to the Bank, permanently reduce the aggregate amount of the Revolving Loan
Commitment; provided that no such reduction shall reduce the aggregate amount of
the Revolving Loan Commitment to an amount less than the aggregate unpaid
principal balance of the Revolving Credit Note on the effective date of such
reduction. Each reduction in the Revolving Loan Commitment shall be in a minimum
amount of $500,000 or an integral multiple thereof.

         2.2 Term Loan A. On February 11, 2003, the Bank extended to the Company
the Term Loan A in an aggregate principal amount of $10,000,000 and on the date
hereof, the aggregate outstanding principal amount on such term loan is
$9,749,998.00. The Term Loan A is and shall be subject to all of the terms and
conditions set forth in this Agreement. The Term Loan A made by the Bank
pursuant hereto is evidenced by the Term Note A. Prior to an Event of Default,
interest shall accrue and be computed on the aggregate unpaid principal amount
from time to time outstanding under the Term Note A as determined in the Term
Note A. All outstanding unpaid principal and accrued interest on the Term Loan A
shall be due and payable on the Termination Date for Term Loan A. The Company
shall pay to the Bank such other charges, costs, expenses or premiums as the
Bank may incur pursuant to the terms of the Term Note A.

         2.3 Interest After Default. After an Event of Default, each of the
Notes shall bear interest at the rate of 3% per annum in excess of the interest
rate specified in such Notes. In no event shall the interest rate under the
Notes exceed the highest rate permitted by law.

         2.4 Loan Account. The Bank will enter as a debit to the Loan Account
the aggregate principal amount of each Obligation as disbursed or issued from
time to time by the Bank. The Bank shall also record in the Loan Account, in
accordance with the Bank's customary accounting practices: accrued interest and
all other charges, expenses and other items properly chargeable to the Company
hereunder or under the Related Documents; all payments made by the Company with
respect to the Obligations, if any; and all other appropriate debits and
credits. The debit balance of the Loan Account shall reflect the amount of the
Obligations and other appropriate

<PAGE>

charges hereunder. Not more frequently than once each month, the Bank shall
render a statement of account of the Loan Account including, with respect to
Revolving Loans, a statement of the outstanding principal balance and the
applicable interest rate, which statement shall be considered correct and
accepted by the Company and conclusively binding upon the Company unless it
notifies the Bank to the contrary within 30 days of the mailing of such
statement by the Bank to the Company; provided, however, that the failure of the
Bank to record any of the foregoing items in the Loan Account shall not limit or
otherwise affect the Company's obligation to repay the Obligations.

         2.5 Lockbox.

             (a) The Company agrees that, upon the request of the Bank, it shall
immediately direct each of its Account debtors and other obligors to make
payments due under their Accounts, instruments and/or chattel paper directly to
a special lockbox to be under the exclusive control of the Bank. If the Company
does not issue such notice within one day after being requested to do so by the
Bank, the Bank is authorized to do so on behalf, and in the name, of the
Company.

             (b) Upon the establishment of the special lockbox referred to in
Section 2.5(a), the Company authorizes and directs the Bank to deposit into a
special collateral account to be established and maintained by the Bank all
drafts, checks and cash payments received in said lockbox or otherwise received
by the Bank. All deposits in said collateral account shall constitute proceeds
of Collateral. The Bank shall apply finally collected funds on deposit in said
collateral account immediately to the Loan Account as payment of the
Obligations, in such order of application as the Bank may determine. The Company
agrees that it shall promptly deliver to the Bank for deposit in said collateral
account all payments received by it, including without limitation all payments
on Accounts, instruments and chattel paper, all cash received by the Company and
all other proceeds of Collateral. All such payments, cash and proceeds shall
immediately be delivered to the Bank in the form received (except for the
Company's endorsement where necessary) and the Company agrees, until so
deposited, such payments, cash and proceeds shall be held in an express trust by
the Company for, and as the exclusive property of, the Bank and shall not be
commingled with any funds or property of the Company.

         2.6 Payments. Whenever any payment to be made hereunder shall be stated
to be due on a day which is not a Business Day, such payment may be made on the
next succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest on the Notes. The Bank may
debit to the depository accounts maintained by the Company with the Bank all
payments on the Obligations when due without prior notice to or consent of the
Company.

         2.7 Prepayments.

             (a) Optional Prepayments. The Company may at its option prepay the
Obligations, in whole or in part. Except as set forth in Section 2.5(b) or in
any cash management agreements entered into from time to time between the
Company and the Bank, partial prepayments shall be in the minimum aggregate
principal amount of $100,000 or a multiple thereof, together with accrued
interest to the date of prepayment on the amount prepaid. There shall be no
prepayment premium except as provided in the Notes. Any prepayments of Term Loan
A or Term Loan B shall be applied in inverse order of the principal installments
due thereon and the Company shall pay the accrued interest to the date of
prepayment on the principal amount of the Term Loan A or Term Loan B being
repaid, as the case may be.


<PAGE>

             (b) Mandatory Prepayment. At any time that the aggregate principal
amount of Revolving Loans outstanding hereunder exceeds the lesser of the
Revolving Loan Commitment or the Borrowing Base, the Company shall immediately
pay the amount of such excess in immediately available funds, together with
interest accrued on the amount of the payment. Ten (10) days after receipt of
the Company's unaudited financial statements for measurement periods ending on
the last day of each Fiscal Quarter of the Company, the Company shall make a
mandatory prepayment of the Term Loan A in an amount equal to fifty percent
(50%) of the Company's "Excess Cash Flow" (as defined below) for the Fiscal
Quarter just ended, such mandatory prepayment to be applied against the
remaining installments of principal in the inverse order of their maturities,
and to continue until the date on which the Term Loan A shall be repaid in full.
For purposes hereof, "Excess Cash Flow" shall mean for each of the Company's
Fiscal Quarters, the dollar amount equal to the Company's Consolidated Net
Income for such period, plus actual interest expense payable during such period
plus depreciation during such period plus amortization during such period minus
un-financed capital expenditures payable during such period minus actual
principal payments on long term debt payable and cash interest paid during such
period minus actual capital lease payments payable during such period.

         2.8 Effect of Regulatory Change. In the event of a Regulatory Change
deemed by the Bank in good faith to be material, the Company shall pay to the
Bank (within ten days after notice by the Bank to the Company of such Regulatory
Change) such amounts as the Bank deems reasonably necessary to compensate the
Bank for the increase in the cost of making or maintaining the Obligations or
the reduction in the rate of return to the Bank on the Obligations resulting
from the Regulatory Change.

         2.9 Security. Payment of all Obligations shall be secured, subject only
to Permitted Liens, by a first priority security interest or Lien on all of the
Property in accordance with this Agreement and the Related Documents.

         2.10 No Obligation to Extend or Forbear. The Company acknowledges and
agrees that the Bank: (a) has no duty or obligation of any kind to, and has made
no representations of any kind or nature that the Bank will (i) extend credit or
any other kind of financial accommodations to the Company after the applicable
Termination Date, or (ii) forbear at any time from the exercise of any of its
rights or remedies under this Agreement, the Related Documents and applicable
law; and (b) may at any time, in its sole and absolute discretion, exercise
whatever rights and remedies the Bank may have under this Agreement, the Related
Documents and applicable law. The Company acknowledges and agrees that the
applicable Obligations shall be due in full on the applicable Termination Date
without further demand.


         SECTION 3 REPRESENTATIONS AND WARRANTIES

             In order to induce the Bank to enter into this Agreement and make

and to own its assets and conduct its business as presently conducted. The

Material Adverse Effect. All of the issued and outstanding capital stock of the
Company has been validly issued and is fully paid and non-assessable, except as

not own, directly or indirectly, more than 1% of the total outstanding shares of
any class of capital stock of any other Person, and (c) there are no outstanding
options,

<PAGE>

warrants or other rights to subscribe for or purchase from any Subsidiary any
capital stock of such Subsidiary or securities convertible into or exchangeable

         3.2 Financial Statements. All of the financial statements heretofore
furnished to the Bank are accurate and complete, were prepared in accordance
with GAAP consistently applied throughout all periods and fairly present the
financial condition and the results of operation of the relevant Person for the
periods and as of the relevant dates thereof, subject to audit and normal
year-end adjustments. There has been no Material Adverse Effect on the business,
properties or condition, financial or otherwise, of the Company and the
Subsidiaries, taken as a whole, since the date of the latest such financial
statements.

         3.3 Authorization. The making, execution, delivery and performance of
this Agreement and the Related Documents by the Company and its Subsidiaries
have each been duly authorized by all necessary corporate action. The valid
execution, delivery and performance of this Agreement, the Related Documents and
the transactions contemplated hereby and thereby, are not and will not be
subject to any approval, consent or authorization of any Government Authority.
This Agreement and the Related Documents are the valid and binding obligations
of the Company and its Subsidiaries enforceable against the Company and its
Subsidiaries in accordance with their respective terms, except as the
enforcement thereof may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws generally affecting the rights of
creditors and subject to general equity principles.

         3.4 Absence of Conflicting Obligations. The making, execution, delivery
and performance of this Agreement and the Related Documents and compliance with
their respective terms do not violate or constitute a default, breach or
violation under any Requirements of Law or any covenant, indenture, deed, lease,
contract, agreement, mortgage, deed of trust, note or instrument to which the
Company or any of its Subsidiaries is a party or by which it is bound.

         3.5 Taxes. The Company has and its Subsidiaries have filed all federal,
state, foreign and local tax returns which were required to be filed, except
those returns for which the due date has been validly extended. The Company has
and its Subsidiaries have paid or made provisions for the payment of all taxes,
assessments, fees and other governmental charges owed, and no tax deficiencies
have been proposed, threatened or assessed against the Company or its
Subsidiaries. There is no pending or, to the best of the Company's knowledge,
threatened tax controversy or dispute as of the date hereof.

         3.6 Absence of Litigation. There is no pending or, to the knowledge of
the Company, threatened litigation or administrative proceeding at law or in
equity which would, if adversely determined, result in a Material Adverse
Effect, and, to the best of the Company's knowledge after diligent inquiry,
there are no presently existing facts or circumstances likely to give rise to
any such litigation or administrative proceeding.

         3.7 Accuracy of Information. All information, certificates or
statements given or made by the Company and its Subsidiaries to the Bank under
this Agreement and the Related Documents were accurate, true and complete in all
material respects when given, continue to be accurate, true and complete as of
the date hereof, and do not contain any untrue statement or omission of a
material fact necessary to make the statements herein or therein not misleading.
There is no fact known to the Company which is not set forth in this Agreement,
the Related Documents or other documents, certificates or statements furnished
to the Bank by or on behalf of the Company or its Subsidiaries in connection
with the transactions contemplated hereby and which will, or which in the future
may (so far as the Company can reasonably foresee), cause a Material Adverse
Effect.

         3.8 Ownership of Property. The Company has good and marketable title to
all of its Property, including, without limitation, the Property reflected in
the balance sheets referred to in Section 3.2 and fee simple title to the
Property subject to the Mortgages. There are no Liens of any nature on any of
the Property except Permitted Liens. All Property useful or necessary in the
Company's and its Subsidiaries' business, whether leased or owned, is in good
condition, repair (ordinary wear and tear excepted) and working order and, to
the best of the

<PAGE>

Company's knowledge after diligent inquiry, conforms to all applicable
Requirements of Law. The Company and its Subsidiaries own (or are licensed to
use) and possess all such patents, trademarks, trade names, service marks,
copyrights and rights with respect to the foregoing as are reasonably necessary
for the conduct of the businesses of the Company and its Subsidiaries as now
conducted and proposed to be conducted without, individually or in the
aggregate, any infringement upon rights of other Persons. SCHEDULE 3.8 contains
a true, correct and complete list of all patents, trademarks, service marks,
trade names and copyrights owned by the Company.

         3.9 Federal Reserve Regulations. The Company will not, directly or
indirectly use any proceeds of the Obligations to: (a) purchase or carry any
"margin stock" within the meaning of Regulation U of the Board of Governors of
the Federal Reserve System (12 C.F.R. 221, as amended); (b) extend credit to
other Persons for any such purpose or refund indebtedness originally incurred
for any such purpose; or (c) otherwise take or permit any action which would
involve a violation of Section 7 of the Securities Exchange Act of 1934, as
amended, or any regulation of the Board of Governors of the Federal Reserve
System.

         3.10 ERISA. The Company and each of its Subsidiaries and anyone under
common control with the Company under Section 4001(b) of ERISA is in compliance

         3.11 Security Interests. The Bank has a legal, valid, perfected and,
except for Permitted Liens, first priority security interest or Lien in the
Collateral, and the Collateral is and at all times shall be free and clear of
all other Liens whatsoever.

         3.12 Places of Business. The principal place of business and chief
executive office of the Company is located at the address specified in Section

account are located and hereafter shall continue to be located at such principal
place of business and chief executive office.

         3.13 Other Names. The business conducted by the Company has not been
conducted under any corporate, trade or fictitious name other than the name The
Oilgear Company, and following the date hereof the Company will not conduct its
business under any corporate, trade or fictitious name unless the Company shall
have delivered at least 30 days' prior written notice to the Bank of such name
change.

         3.14 Not an Investment Company. The Company is not (a) an "investment
company" or a company "controlled by an investment company" within the meaning
of the Investment Company Act of 1940, as amended, or (b) a "holding company" or
a "subsidiary" of a "holding company" or an "affiliate of a "holding company" or
a "subsidiary" of a "holding company" within the meaning of the Public Utility
Holding Company Act of 1935, as amended.

         3.15 No Defaults. Neither the Company nor any Subsidiary is in default
under or in violation of (a) any Requirements of Law, (b) any covenant,
indenture, deed, lease, agreement, mortgage, deed of trust, note or other
instrument to which the Company or any Subsidiary is a party or by which the
Company or any Subsidiary is bound, or to which any of its Property is subject,
or (c) any Indebtedness; or if any default or violation under Sections 3.15(a),
(b) or (c) exists, it is an immaterial default or violation and the failure to
cure such default or violation would not result in a Material Adverse Effect.

         3.16 Environmental Laws. The business of the Company and each of its
Subsidiaries has been operated in full compliance with all Environmental Laws
noncompliance with which would result in a Default or

<PAGE>

a Material Adverse Effect and neither the Company nor any Subsidiary is subject
to any Environmental Liability relating to the conduct of its business or the
ownership of its Property and except as disclosed in the environmental
assessment reports referenced in Section 4.1(q), no facts or circumstances exist
which could give rise to such Environmental Liabilities. No notice has been
served on the Company or any Subsidiary claiming any violation of Environmental
Laws, asserting Environmental Liability or demanding payment or contribution for
Environmental Liability or violation of Environmental Laws.

         3.17 Labor Matters. There are no labor disputes between the Company or
any Subsidiary and any of its employees which individually or in the aggregate,
if resolved in a manner adverse to the Company or a Subsidiary, would result in
a Material Adverse Effect.

         3.18 Restricted Payments. The Company has not, since the date of the
most recent financial statements referred to in Section 3.2, made any Restricted
Payments.

         3.19 Solvency. The Company is not "insolvent," nor will the Company's
incurrence of the Obligations or repayment of the Obligations render the Company
"insolvent." For purposes of this Section 3.19, a corporation is "insolvent" if
(i) the "present fair salable value" (as defined below) of its assets is less
than the amount that will be required to pay its probable liability on its
existing debts and other liabilities (including contingent liabilities) as they
become absolute and matured; (ii) its property constitutes unreasonably small
capital for it to carry out its business as now conducted and as proposed to be
conducted including its capital needs; (iii) it intends to, or believes that it
will, incur debts beyond its ability to pay such debts as they mature (taking
into account the timing and amounts of cash to be received by it and amounts to
be payable on or in respect of debt of it), or the cash available to it after
taking into account all of its other anticipated uses of the cash is anticipated
to be insufficient to pay all such amounts on or in respect of its debt when
such amounts are required to be paid; or (iv) it believes that final judgments
against it in actions for money damages will be rendered at a time when, or in
an amount such that, it will be unable to satisfy any such judgments promptly in
accordance with their terms (taking into account the maximum reasonable amount
of such judgments in any such actions and the earliest reasonable time at which
such judgments might be rendered), or the cash available to it after taking into
account all other anticipated uses of its cash, is anticipated to be
insufficient to pay all such judgments promptly in accordance with their terms.
For purposes of this Section 3.19, the following terms have the following
meanings: (x) the term "debts" includes any legal liability, whether matured or
unmatured, liquidated, absolute, fixed or contingent, (y) the term "present fair
salable value" of assets means the amount which may be realized, within a
reasonable time, either through collection or sale of such assets at their
regular market value and (z) the term "regular market value" means the amount
which a capable and diligent businessman could obtain for the property in
question within a reasonable time from an interested buyer who is willing to
purchase under ordinary conditions.

         3.20 Brokerage. If any broker, agent or finder acted on behalf of the
Company, the fees and expenses of such broker, agent or finder are the
responsibility of and will be paid by the Company and not the Bank.

         3.21 Bank Accounts. SCHEDULE 3.21 lists all banks and other financial
institutions at which the Company and each of its Subsidiaries maintains
deposit, operating or other accounts and such SCHEDULE 3.21 correctly identifies
the name, address and telephone number of each depository, the name in which the
account is held, a description of the purpose of the account, the account

confidential information is not disclosed to third parties. The Company agrees
