                   Amount and Terms of the Revolving Advances

      Section 2.01 Advances. The Lender agrees, on the terms and subject to the
conditions herein set forth, to make Advances to the Borrower from time to time
during the period from the date hereof to and including the Termination Date, or
the earlier termination of the Commitment by the 


<PAGE>


Lender pursuant to Section 7.02 hereof, in an aggregate amount at any time
outstanding not to exceed the Borrowing Base, which Advances made by the Lender
shall be secured by the Collateral. The Advances made by the Lender to the
Borrower under this Section 2.01 are made on a revolving basis and it is
contemplated that the Borrower will request Advances, repay Advances and request
additional Advances. The Borrower agrees to comply with the following procedures
in requesting Advances under this Section 2.01:

            (a) The Borrower will not request any Advance under this Section
      2.01 if, after giving effect to such requested Advance, the sum of the
      outstanding and unpaid Advances under this Section 2.01 or otherwise would
      exceed the Borrowing Base.

            (b) Each request for an Advance under this Section 2.01 shall be
      made to the Lender prior to 3:00 p.m. (Minneapolis time) of the day of the
      requested Advance by the Borrower. Each request for an Advance may be made
      in writing or by telephone, specifying the date of the requested Advance
      and the amount thereof, and shall be by any person reasonably believed by
      the Lender to be an officer or employee of the Borrower which the Borrower
      has notified the Lender in writing is authorized to request Advances under
      this Agreement. Each requested Advance shall be in the amount of $10,000
      or a multiple thereof.

            (c) Upon fulfillment of the applicable conditions set forth in
      Article III hereof, the Lender shall disburse loan proceeds by crediting
      the same to the Borrower's demand deposit account maintained with the
      Lender unless the Lender and the Borrower shall agree in writing to
      another manner of disbursement. Upon request of the Lender, the Borrower
      shall promptly confirm each telephonic request for an Advance by executing
      and delivering an appropriate confirmation certificate to the Lender. The
      Borrower shall be obligated to repay all Advances under this Section 2.01
      notwithstanding the failure of the Lender to receive such confirmation and
      notwithstanding the fact that the person requesting the same was not in
      fact the authorized officer of employee which said person identified
      himself or herself to be unless the Lender commits willful misconduct or
      gross negligence in determining the authorization or identity of such
      person and the Borrower does not receive the proceeds or the benefit of
      such Advance. Any request for an Advance under this Section 2.01, whether
      written or telephonic, shall be deemed to be a representation by the
      Borrower that (i) the condition set forth in Section 2.01(a) hereof has
      been met, and (ii) the conditions set forth in Section 3.02 hereof have
      been met as of the time of the request.

      Section 2.02 Revolving Note. All Advances made by the Lender under Section
2.01 shall be evidenced by and repayable with interest in accordance with the
Revolving Note. The principal of the Revolving Note shall be payable as provided
elsewhere in this Agreement and on the earlier of the Termination Date or
acceleration by the Lender pursuant to Section 7.02 hereof, and shall bear
interest as provided herein.

      Section 2.03 Interest under the Revolving Note. The principal balance of
the Advances outstanding from time to time during any month shall bear interest
(computed on the basis of actual days elapsed in a 360-day year) at the Base
Rate. Notwithstanding the foregoing, so long as no Event of Default exists under
this Agreement, the Borrower shall have the option of fixing the interest rate
on the principal balance of the Advances outstanding from time to time, for
periods commencing on the 


<PAGE>


date elected by the Borrower and ending on the numerically corresponding day in
the first calendar month thereafter (except that each monthly period that
commences on the last Business Day of a calendar month (or on any day for which
there is no numerically corresponding day in the appropriate subsequent calendar
month) shall end on the last Business Day of the appropriate subsequent calendar
month), at the then existing LIBOR Rate plus two and three-quarters percent
(2-3/4%). At the expiration of said monthly period, interest accruing on the
principal balance of the Advances shall be reestablished at the then existing
LIBOR Rate plus two and three-quarters percent (2-3/4%) per annum unless prior
to that time, the Borrower has notified the Lender of its intention to convert
the interest rate accruing on the outstanding principal balance of the Advances
to the Base Rate. Interest accruing on the principal balance of the Advances
outstanding from time to time shall be payable on the first day after the end of
each month and on the Termination Date or earlier demand or prepayment in full.

      Notwithstanding anything to the contrary herein, if the Lender determines
(which determination shall be conclusive) that (i) quotation of interest rates
for the relevant deposits referred to in the definition of LIBOR Rate is not
being provided in the relevant amounts or for the relative maturities for the
purpose of determining the LIBOR Rate; or (ii) the relevant rate of interest
referred to in the definition of LIBOR Rate does not accurately cover the cost
to the Lender of making or maintaining such type of loan;

then the Lender shall forthwith give notice thereof to the Borrower, whereupon
(a) the obligation of the Lender to make Advances subject to the LIBOR Rate as
the case may be, shall be suspended until the Lender notifies the Borrower that
the circumstances giving rise to such suspension no longer exist; and (b) the
interest rate accruing on the outstanding principle balance of the Advances
shall immediately convert to the Base Rate.

      Section 2.04 Voluntary Prepayment; Termination of Agreement by Borrower.
The Borrower may, in its discretion, prepay the Advances in whole at any time or
from time to time in part, without penalty or premium. If the Borrower desires
to terminate this Agreement as of any date other than the Termination Date, the
Borrower shall give at least 30 days' prior written notice to the Lender of the
Borrower's intention to do so. Upon compliance with the foregoing requirement
and subject to payment and performance of all the Borrower's obligations to the
Lender, the Borrower may obtain any release or termination of the Security
Interest in the Collateral to which the Borrower is otherwise entitled by law.
The Borrower acknowledges and agrees that it has no right or ability to reduce
in part the Commitment without the prior written consent of the Lender.

      Section 2.05 Mandatory Prepayment. Without notice or demand, if the sum of
the outstanding principal balance of the Advances shall at any time exceed the
Borrowing Base, the Borrower shall repay the Advances to the extent necessary to
reduce the sum of the outstanding principal balance of the Advances to the
Borrowing Base within ten (10) Business Days.

      Section 2.06 Payment. All payments of principal of and interest on the
Advances shall be made to the Lender in immediately available funds no later
than 3:00 p.m. (Minneapolis time) on the date due. The Borrower agrees that the
amount shown on the books and records of the Lender as being the aggregate
amount of the Advances outstanding shall be prima facie evidence of the
principal amounts of the Revolving Note. The Borrower hereby authorizes the
Lender to charge against the Borrower's account with the Lender an amount equal
to the principal and interest from time to time due 


<PAGE>


and payable to the Lender under this Agreement and the Revolving Note, and
further authorizes the Lender, in its discretion at any time or from time to
time and without request by the Borrower, to make an Advance to the extent
necessary to pay any such amounts of principal and interest. In addition, the
Borrower further authorizes the Lender, in its discretion at any time or from
time to time and without request by the Borrower, but only after the Lender has
given written notice thereof to the Borrower, to make an Advance to the extent
necessary to pay any fees, costs or expenses hereunder or under the Security
Agreement.

      Section 2.07. Payment on Non-Business Days. Whenever any payment to be
made hereunder or under the Revolving Note 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 hereunder or fees hereunder, as the case may
be.

      Section 2.08. Use of Proceeds. The proceeds of all Advances subsequent to
the initial Advance shall be used by the Borrower for ordinary working capital
purposes, equipment purchases, and for general corporate purposes.

      Section 2.09 Default Rate of Interest. Upon the occurrence of an Event of
Default or at any time thereafter until such Event of Default is cured to the
written satisfaction of the Lender, the Lender may, in addition to the rights
and remedies provided in Section 7.02, increase the rate of interest payable
pursuant to the Revolving Note to the Base Rent plus two percent (2.0%)
("Default Rate"), which Default Rate shall change when and as often as the Base
Rate changes.

      Section 2.10 Over Advance Fee. Without affecting the Borrower's obligation
to immediately repay the Lender the amount of each overadvance in accordance
with Section 2.05 of this Agreement, Borrower agrees to pay Lender a fee (the
"Overadvance Fee") in an amount equal to two percent (2%) per annum for the
amount overadvanced for each day any overadvance exists. All such fees shall be
computed on the basis of a three hundred and sixty (360) day year for the actual
number of days elapsed.

      Section 2.11 Unused Line Fee. If the average outstanding daily principal
balance of all advances made by the Lender to the Borrower under Section 2.1 of
this Agreement shall be less than the Commitment in any calendar month, Borrower
shall pay to Lender on the first (1st) day of the next succeeding calendar month
a fee (the "Unused Line Fee") equal to one quarter of one percent (.25%) per
annum of the amount by which the Commitment exceeds the average outstanding
daily principal balance of advances in respect of such month.

      or order for the payment of money in excess of $50,000 and the continuance

      the Lender may determine are likely to occur in the future, result in the
      imposition of a lien on the assets of the Borrower in favor of the Plan;
      or


<PAGE>


            (m) An event of default shall occur under the Security Agreement or

      which it shall have set aside on its books adequate reserves therefor) or
      notice of any state or federal tax liens shall be filed or issued.

            (q) The Lender shall determine that the due and punctual payment of
      the Revolving Note is materially impaired.

      Section 7.02 Rights and Remedies. Upon the occurrence of an Event of
Default or at any time thereafter until such Event of Default is cured to the
written satisfaction of the Lender, the Lender may exercise any or all of the
following rights and remedies:

            (a) The Lender may, by notice to the Borrower, declare the entire
      unpaid principal amount the Note, all interest accrued and unpaid thereon,
      and all other amounts payable under the Loan Documents to be forthwith due
      and payable, whereupon the Revolving Note, all such accrued interest and
      all such amounts shall become and be forthwith due and payable, without
      presentment, demand, protest or further notice of any kind, all of which
      are hereby expressly waived by the Borrower;

            (b) The Lender may, without prior notice to the Borrower and without
      further action, apply or offset against any and all money of the Borrower
      maintained in any account with the Lender to the payment of the Revolving
      Note, including interest accrued thereon, and of all other sums then owing
      by the Borrower hereunder; provided, however, after the completion of any
      such application by the Lender, the Lender will promptly provide written
      notice of such application to the Borrower;

            (c) The Lender may exercise and enforce its rights and remedies
      under the Security Agreement and under any other Loan Documents;

            (d) The Borrower hereby grants the Lender the right to possess and

                  (i) The Lender may take possession of the Premises only upon
            the occurrence of an Event of Default;

                  (ii) The Lender may use the Premises only to hold, process,
            manufacture and sell or otherwise dispose of goods which are
            inventory, or to provide services under contracts for receivable, or
            to use, operate, store, liquidate or realize upon goods which 


<PAGE>


            are equipment or any other Collateral and for other purposes which
            the Lender may in good faith deem to be related or incidental
            purposes;

                  (iii) The right of the Lender to hold the Premises shall cease
            and terminate upon the earlier of (A) payment in full and discharge
            of all indebtedness under this Agreement; (B) final sale or
            disposition of all goods constituting Collateral (including both
            inventory and equipment) and delivery of all such goods to

                  (iv) The Lender shall not be obligated to pay or account for
            any rent or other compensation for this grant or for the possession,

                  (v) The Borrower acknowledges and agrees that the breach of
            this grant is not fully compensable by money damages, and that,
            accordingly, this grant may be enforced by an action for specific
            performance.

            (e) The Lender may exercise any other rights and remedies available
      to it by law or agreement.

Notwithstanding the foregoing, upon the occurrence of an Event of Default
described in Section 7.01(h) hereof, the entire unpaid principal amount of the
Revolving Note, all interest accrued and unpaid thereon, and all other amounts
payable under the Loan Documents shall be immediately due and payable without
presentment, demand, protest or notice of any kind.


                                  ARTICLE VIII
                                 MISCELLANEOUS

      Section 8.01 No Waiver; Cumulative Remedies. No failure or delay on the
part of the Lender in exercising any right, power or remedy under the Loan
Documents shall operate as a waiver thereof; nor shall any single or partial
exercise of any such right, power or remedy preclude any other or further
exercise thereof or the exercise of any other right, power or remedy under the
Loan Documents. The remedies provided in the Loan Documents are cumulative and
not exclusive of any remedies provided by law.

      Section 8.02 Amendments, Etc. No amendment, modification, termination or
waiver of any provision of any Loan Document or consent to any departure by the
Borrower therefrom shall be effective unless the same shall be in writing and
signed by the Lender and by an authorized officer of the Borrower, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given. No notice to or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances.

      Section 8.03 Addresses for Notices, Etc. Except as otherwise expressly
provided herein, all notices, requests, demands and other communications
provided for under the Loan Documents shall be in writing and shall be (a)

deposit in the mail if delivered by mail, (c) one Business Day after sending if
sent by overnight courier, or (d) the date of transmission if delivered by
telecopy.

      Section 8.04 Costs and Expenses. The Borrower agrees to pay on demand all
costs and expenses incurred by the Lender in connection with the negotiation,
preparation, execution, administration, amendment, auditing or enforcement of
the Loan Documents and the other instruments and documents to be delivered
thereunder, including the reasonable fees and out-of-pocket expenses of counsel
for the Lender with respect thereto.

      Section 8.05 Execution in Counterparts. This Agreement and the Security
Agreement may be executed in any number of counterparts, each of which when so
executed and delivered shall be deemed to be an original and all of which
counterparts of this Agreement or the Security Agreement, as the case may be,
taken together, shall constitute but one and the same instrument.


<PAGE>


      Section 8.06 Binding Effect, Assignment. The Loan Documents shall be
binding upon and inure to the benefit of the Borrower and the Lender and their
respective successors and assigns, except that the Borrower shall not have the
right to assign its rights thereunder or any interest therein without the prior
written consent of the Lender.

      Section 8.07 Governing Law. The Loan Documents shall be governed by, and
construed in accordance with, the laws of the State of Minnesota.

      Section 8.08 Further Documents. The Borrower will from time to time
execute and deliver or endorse any and all instruments, documents, conveyances,
assignments, security agreements, financing statements and other agreements and
writings that the Lender may reasonably request in order to secure, protect,
perfect or enforce the Lender's Security Interest in the Collateral or the
rights of the Lender under the Loan Documents (but any failure to request or
assure that the Borrower executes, delivers or endorses any such item shall not
affect or impair the validity, sufficiency or enforceability of this Agreement
and the security interest in the Collateral, regardless of whether any such item
was or was not executed, delivered or endorsed in a similar context or on a
prior occasion).

      Section 8.09 Indemnity. In addition to the payment of costs and expenses
pursuant to Section 8.04 hereof and the environmental indemnity pursuant to
Section 5.03 hereof, the Borrower agrees to indemnify, defend and hold harmless
the Lender, and any of its participants, parent corporations, subsidiary
corporations, affiliated corporations, successor corporations, and all present
and future officers, directors, employees and agents of the foregoing (the
"Indemnitees"), from and against (i) any and all transfer taxes, documentary
taxes, assessments or charges made by any governmental authority by reason of
the execution and delivery of this Agreement and the other Loan Documents or the
making of the borrowings hereunder, and (ii) any and all liabilities, losses,
damages, penalties, judgments, suits, claims, costs and expenses of any kind or
nature whatsoever (including, without limitation, the reasonable fees and
disbursements of counsel) in connection with any investigative, administrative
or judicial proceedings, whether or not such Indemnitee shall be designated a
party thereto, which may be imposed on, incurred by or asserted against such
Indemnitee, in any manner relating to or arising out of or in connection with
the making of the borrowings hereunder, this Agreement and all other Loan
Documents or the use or intended use of the proceeds of the borrowings hereunder
(the "Indemnified Liabilities"); provided, however, the Borrower shall not be
required to indemnify the Indemnitees for any liabilities, losses, damages,
penalties, judgments, suits, claims, costs or expenses to the extent caused by
such Indemnitees' gross negligence or willful misconduct or by such Indemnitees'
violation of banking laws. If any investigative, judicial or administrative
proceeding arising from any of the foregoing is brought against any Indemnitee,
upon request of such Indemnitee, the Borrower, or counsel designated by the
Borrower and reasonably satisfactory to the Indemnitee, will resist and defend
such action, suit or proceeding to the extent and in the manner agreed upon by
the Indemnitee and the Borrower, at the Borrower's sole cost and expense. Each
Indemnitee will use its best efforts to cooperate in the defense of any such
action, suit or proceeding. If the foregoing undertaking to indemnify, defend
and hold harmless may be held to be unenforceable because it violates any law or
public policy, the Borrower shall nevertheless make the maximum contribution to
the payment and satisfaction of each of the Indemnified Liabilities which is
permissible under applicable law. The obligation of the Borrower under this
Section 8.09 shall survive the termination of this Agreement.

      Section 8.10 Severability of Provisions. Any provision of this Agreement
which is prohibited or unenforceable shall be ineffective to the extent of such
prohibition or unenforceability without invalidating the remaining provisions
hereof.

      Section 8.11 Headings. Article and Section headings in this Agreement are
included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.

      Section 8.12 Confidentiality. The Lender agrees to keep confidential (and
to cause its respective officers, directors, employees, agents and
representatives to keep confidential) all information, materials and documents
furnished to the Lender (the "Disclosed Information"). Notwithstanding the
foregoing, the Lender shall be permitted to disclose Disclosed Information (i)
to such of its officers, directors, employees, agents and representatives as
need to know such Disclosed Information in connection with its participation in
the transaction contemplated by this Agreement (which officers, directors,
employees, agents and representatives the Lender shall cause to keep
confidential the Disclosed Information); (ii) to the extent required by
applicable laws and regulations or by any subpoena or similar legal process, or
requested by any governmental agency or authority; (iii) to the extent such
Disclosed Information (A) becomes publicly available other than as a result of a
breach of this Section, (B) becomes available to the Lender on a
non-confidential basis from a source other than the Borrower or (C) was
available to the Lender on a non-confidential basis prior to its disclosure to
the Lender by the Borrower; (iv) to the extent the Borrower shall have consented
to such disclosure in writing; (v) in connection with the enforcement of any
rights or remedies or the sale of any collateral pursuant to the provisions of
any of the Loan Documents; or (vi) in connection with any potential assignment
or participation, provided that the prospective assignee or participant shall
have agreed in writing prior to receipt of any Disclosed Information to be bound
by the confidentiality provisions of this Section.

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their respective officers thereunto duly authorized, as of the date
first above written.
