WHICH MAY BE DESCRIBED ON ANY EXHIBIT OR SCHEDULE ATTACHED TO THIS AGREEMENT
("LOAN"). BORROWER UNDERSTANDS AND AGREES THAT: (A) IN GRANTING, RENEWING, OR
EXTENDING ANY LOAN, LENDER IS RELYING UPON BORROWER'S REPRESENTATIONS,
WARRANTIES, AND AGREEMENTS AS SET FORTH IN THIS AGREEMENT, AND (B) ALL SUCH
LOANS SHALL BE AND REMAIN SUBJECT TO THE TERMS AND CONDITIONS OF THIS AGREEMENT.

TERM. This Agreement shall be effective as of December 22, 2000, and shall
continue in full force and effect until such time as all of Borrower's Loans in
favor of Lender have been paid in full, including principal, interest, costs,
expenses, attorneys' fees, and other fees and charges, or until such time as
the parties may agree in writing to terminate this Agreement.

LINE OF CREDIT. Lender agrees to make Advances to Borrower from time to time
from the date of this Agreement to the Expiration Date, provided the aggregate
amount of such Advances outstanding at any time does not exceed the Borrowing
Base. Within the foregoing limits, Borrower may borrow, partially or wholly
prepay, and reborrow under this Agreement as follows:

     CONDITIONS PRECEDENT TO EACH ADVANCE. Lender's obligation to make any
     Advance to or for the account of Borrower under this Agreement is subject
     to the following conditions precedent, with all documents, instruments,
     opinions, reports, and other items required under this Agreement to be in
     form and substance satisfactory to Lender:

          (1) Lender shall have received evidence that this Agreement and all
          Related Documents have been duly authorized, executed, and delivered
          by Borrower to Lender.

          (2) Lender shall have received such opinions of counsel, supplemental
          opinions, and documents as Lender may request.

          (3) The security interests in the Collateral shall have been duly
          authorized, created, and perfected with first lien priority and shall
          be in full force and effect.

          (4) All guaranties required by Lender for the credit facility(ies)
          shall have been executed by each Guarantor, delivered to Lender, and
          be in full force and effect.

          (5) Lender, at its option and for its sole benefit, shall have
          conducted an audit of Borrower's Accounts, Equipment, books, records,
          and operations, and Lender shall be satisfied as to their condition.

          (6) Borrower shall have paid to Lender all fees, costs, and expenses
          specified in this Agreement and the Related Documents as are then due
          and payable.

          (7) There shall not exist at the time of any Advance a condition which
          would constitute an Event of Default under this Agreement, and
          Borrower shall have delivered to Lender the compliance certificate
          called for in the paragraph below titled "Compliance Certificate."

     MAKING LOAN ADVANCES. Advances under this credit facility, as well as
     directions for payment from Borrower's accounts, may be requested orally or
     in writing by authorized persons. Lender may, but need not, require that
     all oral requests be confirmed in writing. Each Advance shall be
     conclusively deemed to have been made at the request of and for the benefit
     of Borrower (1) when credited to any deposit account of Borrower maintained
     with Lender or (2) when advanced in accordance with the instructions of an
     authorized person. Lender, at its option, may set a cutoff time, after
     which all requests for Advances will be treated as having been requested on
     the next succeeding Business Day.

     MANDATORY LOAN REPAYMENTS. If at any time the aggregate principal amount of
     the outstanding Advances shall exceed the applicable Borrowing Base,
     Borrower, immediately upon written or oral notice from Lender, shall pay to
     Lender an amount equal to the difference between the outstanding principal
     balance of the Advances and the Borrowing Base. On the Expiration Date,
     Borrower shall pay to Lender in full the aggregate unpaid principal amount
     of all Advances then outstanding and all accrued unpaid interest, together
     with all other applicable fees, costs and charges, if any, not yet paid.

     LOAN ACCOUNT. Lender shall maintain on its books a record of account in
     which Lender shall make entries for each Advance and such other debits and
     credits as shall be appropriate in connection with the credit facility.
     Lender shall provide Borrower with periodic statements of Borrower's
     account, which statements shall be considered to be correct and
     conclusively binding on Borrower unless Borrower notifies Lender to the
     contrary within thirty (30) days after Borrower's receipt of any such
     statement which Borrower deems to be incorrect.

COLLATERAL. To secure payment of the Primary Credit Facility and performance of
all other Loan, obligations and duties owed by Borrower to Lender, Borrower
(and others, if required) shall grant to Lender Security Interests in such
property and assets as Lender may require. Lender's Security Interests in the

     appropriate location or locations. Borrower hereby appoints Lender as its

     necessary to perfect or to continue any Security Interest. Lender may at
     any time, and without further authorization from Borrower, file a carbon,
     photograph, facsimile, or other reproduction of any financing statement for
     use as a financing statement. Borrower will reimburse Lender for all
     expenses for the perfection, termination, and the continuation of the
     perfection of Lender's security interest in the Collateral. Borrower
     promptly will notify Lender of any change in Borrower's name including any

     (4) the properties insured; (5) the then current property values on the

     applicable, the actual cash value or replacement cost of any Collateral.
     The cost of such appraisal shall be paid by Borrower.

     operations, unless specifically consented to the contrary by Lender in
     writing.

     indebtedness and obligations, including without limitation all assessments,

     income, or profits.

     PERFORMANCE. Perform and comply, in a timely manner, with all terms,
     conditions, and provisions set forth in this Agreement, in the Related

     expense, all such investigations, studies, samplings and testings as may be
     requested by Lender or any governmental authority relative to any
     substance, or any waste or by-product of any substance defined as toxic or
     a hazardous substance under applicable federal, state, or local law, rule,
     regulation, order or directive, at or affecting any property or any

     governmental authorities applicable to the conduct of Borrower's
     properties, businesses and operations, and to the use or occupancy of the
     Collateral, including without limitation, the Americans With Disabilities
     Act. Borrower may contest in good faith any such law, ordinance, or
     regulation and withhold compliance during any proceeding, including
     appropriate appeals, so long as Borrower has notified Lender in writing
     prior to doing so and so long as, in Lender's sole opinion, Lender's
     interests in the Collateral are not jeopardized. Lender may require
     Borrower to post adequate security or a surety bond, reasonably
     satisfactory to Lender, to protect Lender's interest.

     INSPECTION. Permit employees or agents of Lender at any reasonable time to
     inspect any and all Collateral for the Loan or Loans and Borrower's other

     (including without limitation computer generated records and computer
     software programs for the generation of such records) in the possession of
     a third party, Borrower, upon request of Lender, shall notify such party to
     permit Lender free access to such records at all reasonable times and to
     provide Lender with copies of any records it may request, all at Borrower's
     expense.

     COMPLIANCE CERTIFICATES. Unless waived in writing by Lender, provide Lender
     at least annually and at the time of each disbursement of Loan proceeds,
     with a certificate executed by Borrower's chief financial officer, or other

     and warranties set forth in this Agreement are true and correct as of the
     date of the certificate and further certifying that, as of the date of the
     certificate, no Event of Default exists under this Agreement.

     ENVIRONMENTAL COMPLIANCE AND REPORTS. Borrower shall comply in all respects
     with any and all Environmental Laws; not cause or permit to exist, as a
     result of an intentional or unintentional action or omission on Borrower's
     part or on the part of any third party, on property owned and/or occupied
     by Borrower, any environmental activity where damage may result to the
     environment, unless such environmental activity is pursuant to and in
     compliance with the conditions of a permit issued by the appropriate
     federal, state or local governmental authorities; shall furnish to Lender
     promptly and in any event within thirty (30) days after receipt thereof a
     copy of any notice, summons, lien, citation, directive, letter or other
     communication from any governmental agency or instrumentality concerning

     connection with any environmental activity whether or not there is damage
     to the environment and/or other natural resources.

     ADDITIONAL ASSURANCES. Make, execute and deliver to Lender such promissory
     notes, mortgages, deeds of trust, security agreements, assignments,
     financing statements, instruments, documents and other agreements as Lender
     or its attorneys may reasonably request to evidence and secure the Loans
     and to perfect all Security Interests.

LENDER'S EXPENDITURES. If any action or proceeding is commenced that would
materially affect Lender's interest in the Collateral or if Borrower fails to
comply with any provision of this Agreement or any Related Documents, including
but not limited to Borrower's failure to discharge or pay when due any amounts
Borrower is required to discharge or pay under this Agreement or any Related
Documents, Lender on Borrower's behalf may (but shall not be obligated to) take
any action that Lender deems appropriate, including but not limited to
discharging or paying all taxes, liens, security interests, encumbrances and
other claims, at any time levied or placed on any Collateral and paying all
costs for insuring, maintaining and preserving any Collateral. All such
expenditures incurred or paid by Lender for such purposes will then bear
interest at the rate charged under the Note from the date incurred or paid by
Lender to the date of repayment by Borrower. All such expenses will become a
part of the Indebtedness and, at Lender's

                                  (CONTINUED)                             PAGE 5
================================================================================

option, will (A) be payable on demand; (B) be added to the balance of the Note
and be apportioned among and be payable with any installment payments to become
due during either (1) the term of any applicable insurance policy; or (2) the
remaining term of the Note; or (C) be treated as a balloon payment which will be
due and payable at the Note's maturity.

NEGATIVE COVENANTS. Borrower covenants and agrees with Lender that while this
Agreement is in effect, Borrower shall not, without the prior written consent
of Lender:

     INDEBTEDNESS AND LIENS. (1) Except for trade debt incurred in the normal
     course of business and indebtedness to Lender contemplated by this
     Agreement, create, incur or assume indebtedness for borrowed money,
     including capital leases, (2) sell, transfer, mortgage, assign, pledge,
     lease, grant a security interest in, or encumber any of Borrower's assets
     (except as allowed as Permitted Liens), or (3) sell with recourse any of
     Borrower's accounts, except to Lender.

     CONTINUITY OF OPERATIONS. (1) Engage in any business activities
     substantially different than those in which Borrower is presently engaged,
     (2) cease operations, liquidate, merge, transfer, acquire or consolidate
     with any other entity, change its name, dissolve or transfer or sell
     Collateral out of the ordinary course of business, or (3) pay any
     dividends on Borrower's stock (other than dividends payable in its stock),
     provided, however that notwithstanding the foregoing, but only so long as
     no Event of Default has occurred and is continuing or would result from
     the payment of dividends, if Borrower is a "Subchapter S Corporation" (as
     defined in the Internal Revenue Code of 1986, as amended), Borrower may
     pay cash dividends on its stock to its shareholders from time to time in
     amounts necessary to enable the shareholders to pay income tax and make
     estimated income tax payments to satisfy their liabilities under federal
     and state law which arise solely from their status as Shareholders of a
     Subchapter S Corporation because of their ownership of shares of
     Borrower's stock, or purchase or retire any of Borrower's outstanding
     shares or alter or amend Borrower's capital structure.

     LOANS, ACQUISITIONS AND GUARANTIES. (1) Loan, invest in or advance money
     or assets, (2) purchase, create or acquire any interest in any other
     enterprise or entity, or (3) incur any obligation as surety or guarantor
     other than in the ordinary course of business.

CESSATION OF ADVANCES. If Lender has made any commitment to make any Loan to
Borrower, whether under this Agreement or under any other agreement, Lender
shall have no obligation to make Loan Advances or to disburse Loan proceeds if:
(A) Borrower or any Guarantor is in default under the terms of this Agreement
or any of the Related Documents or any other agreement that Borrower or any
Guarantor has with Lender; (B) Borrower or any Guarantor dies, becomes
incompetent or becomes insolvent, files a petition in bankruptcy or similar
proceedings, or is adjudged a bankrupt; (C) there occurs a material adverse
change in Borrower's financial condition, in the financial condition of any
Guarantor, or in the value of any Collateral securing any Loan; or (D) any
Guarantor seeks, claims or otherwise attempts to limit, modify or revoke such
Guarantor's guaranty of the Loan or any other loan with Lender; or (E) Lender
in good faith deems itself insecure, even though no Event of Default shall have
occurred.

RIGHT OF SETOFF. To the extent permitted by applicable law, Lender reserves a
right of setoff in all Borrower's accounts with Lender (whether checking,
savings, or some other account). This includes all accounts Borrower holds
jointly with someone else and all accounts Borrower may open in the future.
However, this does not include any IRA or Keogh accounts, or any trust accounts
for which setoff would be prohibited by law. Borrower authorizes Lender, to the
extent permitted by applicable law, to charge or setoff all sums owing on the
indebtedness against any and all such accounts.

DEFAULT. Each of the following shall constitute an Event of Default under this
Agreement:

     PAYMENT DEFAULT. Borrower fails to make any payment when due under the
     Loan.

     OTHER DEFAULTS. Borrower fails to comply with or to perform any other term,
     obligation, covenant or condition contained in this Agreement or in any of
     the Related Documents or to comply with or to perform any term,
     obligation, covenant or condition contained in any other agreement between
     Lender and Borrower.

     DEFAULT IN FAVOR OF THIRD PARTIES. Borrower or any Grantor defaults under
     any loan, extension of credit, security agreement, purchase or sales
     agreement, or any other agreement, in favor of any other creditor or
     person that may materially affect any of Borrower's or any Grantor's
     property or Borrower's or any Grantor's ability to repay the Loans or
     perform their respective obligations under this Agreement or any of the
     Related Documents.

     FALSE STATEMENTS. Any warranty, representation or statement made or
     furnished to Lender by Borrower or on Borrower's behalf under this
     Agreement, the Note, or the Related Documents is false or misleading in any
     material respect, either now or at the time made or furnished or becomes
     false or misleading at any time thereafter.

     INSOLVENCY. The dissolution or termination of Borrower's existence as a
     going business, the insolvency of Borrower, the appointment of a receiver
     for any part of the Borrower's property, any assignment for the benefit
     of creditors, any type of creditor workout, or the commencement of any
     proceeding under any bankruptcy or insolvency laws by or against Borrower.

     DEFECTIVE COLLATERALIZATION. This Agreement or any of the Related
     Documents ceases to be in full force and effect (including failure of any
     collateral document to create a valid and perfected security interest or
     lien) at any time and for any reason.

     CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
     forfeiture proceedings, whether by judicial proceeding, self-help,
     repossession or any other method, by any creditor of Borrower or by any
     governmental agency against any collateral securing the Loan. This includes
     a garnishment of any of Borrower's accounts, including deposit accounts,
     with Lender. However, this Event of Default shall not apply if there is a
     good faith dispute by Borrower as to the validity or reasonableness of the
     claim which is the basis of the creditor or forfeiture proceeding and if
     Borrower gives Lender written notice of the creditor or forfeiture
     proceeding and deposits with Lender monies or a surety bond for the
     creditor or forfeiture proceeding, in an amount determined by Lender, in
     its sole discretion, as being an adequate reserve or bond for the dispute.

     EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with
     respect to any Guarantor of any of the Indebtedness or any Guarantor dies
     or becomes incompetent, or revokes or disputes the validity of, or
     liability under, any Guaranty of the Indebtedness.

     CHANGE IN OWNERSHIP. Any change in ownership of twenty-five percent (25%)
     or more of the common stock of Borrower.

     ADVERSE CHANGE. A material adverse change occurs in Borrower's financial
     condition, or Lender believes the prospect of payment or performance of the
     Loan is impaired.

     INSECURITY. Lender in good faith believes itself insecure.

     EFFECT OF AN EVENT OF DEFAULT. If any Event of Default shall occur, except
     where otherwise provided in this Agreement or the Related Documents, all
     commitments and obligations of Lender under this Agreement or the Related
     Documents or any other agreement immediately will terminate (including
     any obligation to make further Loan Advances or disbursements), and, at
     Lender's option, all Indebtedness immediately will become due and payable,
     all without notice of any kind to Borrower, except that in the case of an
     Event of Default of the type described in the "Insolvency" subsection
     above, such acceleration shall be automatic and not optional. In addition,
     Lender shall have all the rights and remedies provided in the Related
     Documents or available at law, in equity, or otherwise. Except as may be
     prohibited by applicable law, all of the Lender's rights and remedies
     shall be cumulative and may be exercised singularly or concurrently.
     Election by Lender to pursue any remedy shall not exclude pursuit of any
     other remedy, and an election to make expenditures or to take action to
     perform an obligation of Borrower or of any Guarantor shall not affect
     Lender's right to declare a default and to exercise its rights and
     remedies.

MISCELLANEOUS PROVISIONS. The following miscellaneous provisions are part of
this Agreement:

     AMENDMENTS. This Agreement, together with any Related Documents,
     constitutes the entire understanding and agreement of the parties as to the
     matters set forth in this Agreement. No alteration of or amendment to this
     Agreement shall be effective unless given in writing and signed by the
     party or parties sought to be charged or bound by the alteration or
     amendment.

     ATTORNEYS' FEES; EXPENSES. Borrower agrees to pay upon demand all of
     Lender's costs and expenses, including Lender's attorneys' fees and
     Lender's legal expenses, incurred in connection with the enforcement of
     this Agreement. Lender may hire or pay someone else to help enforce this
     Agreement, and Borrower shall pay the costs and expenses of such
     enforcement. Costs and expenses include Lender's attorneys' fees and legal
     expenses whether or not there is a lawsuit, including attorneys' fees and
     legal expenses for bankruptcy proceedings (including efforts to modify or
     vacate any automatic stay or injunction), appeals, and any anticipated
     post-judgment collection services. Borrower also shall pay all court costs
     and such additional fees as may be directed by the court.

     CAPTION HEADINGS. Caption headings in this Agreement are for convenience
     purposes only and are not to be used to interpret or define the provisions
     of this Agreement.

     CONSENT OF LOAN PARTICIPATION. Borrower agrees and consents to Lender's
     sale or transfer, whether now or later, of one or more participation
     interests in the Loan to one or more purchasers, whether related or
     unrelated to Lender. Lender may provide, without any limitation whatsoever,
     to any one or more purchasers, or potential purchasers, any information or
     knowledge Lender may have about Borrower or about any other matter relating
     to the Loan, and Borrower hereby waives any rights to privacy Borrower may
     have with respect to such matters. Borrower additionally waives any and all
     notices of sale of participation interests, as well as all notices of any
     repurchase of such participation interests. Borrower also agrees that the
     purchasers of any such participation interests will be considered as the
     absolute owners of such interests in the Loan and will have all the rights
     granted under the participation agreement or agreements governing the sale
     of such participation interests. Borrower further waives all rights of
     offset or counterclaim that it may have now or later against Lender or
     against any purchaser of such a participation interest and unconditionally
     agrees that either Lender or such purchaser may enforce Borrower's
     obligation under the Loan irrespective of the failure or insolvency of any
     holder of any interest in the Loan. Borrower further agrees that the
     purchaser of any such participation interests may enforce its interests
     irrespective of any personal claims or defenses that Borrower may have
     against Lender.

     GOVERNING LAW. THIS AGREEMENT WILL BE GOVERNED BY, CONSTRUED AND ENFORCED
     IN ACCORDANCE WITH FEDERAL LAW AND THE LAWS OF THE STATE OF WISCONSIN. THIS
     AGREEMENT HAS BEEN ACCEPTED BY LENDER IN THE STATE OF WISCONSIN.

     CHOICE OF VENUE. If there is a lawsuit, Borrower agrees upon Lender's
     request to submit to the jurisdiction of the courts of Milwaukee County,
     State of Wisconsin.

     NO WAIVER BY LENDER. Lender shall not be deemed to have waived any rights
     under this Agreement unless such waiver is given in writing and signed by
     Lender. No delay or omission on the part of Lender in exercising any right
     shall operate as a waiver of such right or any other right. A waiver by
     Lender of a provision of this Agreement shall not prejudice or constitute a
     waiver of Lender's right otherwise to demand strict compliance with that
     provision or any other provision of this Agreement. No prior waiver by
     Lender, nor any course of dealing between Lender and Borrower, or between
     Lender and any Grantor, shall constitute a waiver of any of Lender's rights
     or of any of Borrower's or any Grantor's obligations as to any future
     transactions. Whenever the consent of Lender is required under this
     Agreement, the granting of such consent by Lender in any instance shall not
     constitute continuing consent to subsequent instances where such consent is
     required and in all cases such consent may be granted or withheld in the
     sole discretion of Lender.

     NOTICES. Any notice required to be given under this Agreement shall be
     given in writing, and shall be effective when actually delivered, when
     actually received by telefacsimile (unless otherwise required by law), when
     deposited with a nationally recognized overnight courier, or, if mailed,
     when deposited in the United States mail, as first class, certified or
     registered mail postage prepaid, directed to the addresses shown near the
     beginning of this Agreement. Any party may change its address for notices
     under this Agreement by giving formal written notice to the other parties,
     specifying that the purpose of the notice is to change the party's address.
     For notice purposes, Borrower agrees to keep Lender informed at all times
     of Borrower's current address. Unless otherwise provided or required by
     law, if there is more than one Borrower, any notice given by Lender to any
     Borrower is deemed to be notice given to all Borrowers.

     SEVERABILITY. If a court of competent jurisdiction finds any provision of
     this Agreement to be illegal, invalid, or unenforceable as to any
     circumstance, that finding shall not make the offending provision illegal,
     invalid, or unenforceable as to any other circumstance. If feasible, the
     offending provision shall be considered modified so that it becomes legal,
     valid and enforceable. If the offending provision cannot be so modified, it
     shall be considered deleted from this Agreement. Unless otherwise required
     by law, the illegality, invalidity, or unenforceability of any provision
     of this Agreement shall not affect the legality, validity or enforceability
     of any other provision of this Agreement shall not affect the legality,
     validity or enforceability of any other provision of this Agreement.

     SUBSIDIARIES AND AFFILIATES OF BORROWER. To the extent the context of any
     provisions of this Agreement makes it appropriate, including without
     limitation any representation, warranty or covenant, the word "Borrower" as
     used in this Agreement shall include all of Borrower's subsidiaries and
     affiliates. Notwithstanding the foregoing however, under no circumstances
     shall this Agreement be construed to require Lender to make any Loan or
     other financial accommodation to any of Borrower's subsidiaries or
     affiliates.

     SUCCESSOR AND ASSIGNS. All covenants and agreements contained by or on
     behalf of Borrower shall bind Borrower's successors and assigns and shall
     inure to the benefit of Lender and its successors and assigns. Borrower
     shall not, however, have the right to assign Borrower's rights under this
     Agreement or any interest therein, without the prior written consent of
     Lender.

     SURVIVAL OF REPRESENTATIONS AND WARRANTIES. Borrower understands and agrees
     that in extending Loan Advances, Lender is relying on all representations,
     warranties, and covenants made by Borrower in this Agreement or in any
     certificate or other instrument delivered by Borrower to Lender under this
     Agreement or the Related Documents. Borrower further agrees that regardless
     of any investigation made by Lender, all such representations, warranties
     and covenants will survive the extension of Loan Advances and delivery to
     Lender of the Related Documents, shall be continuing in nature, shall be
     deemed made and redated by Borrower at the time each Loan Advance is made,
     and shall remain in full force and effect until such time as Borrower's
     Indebtedness shall be paid in full, or until this Agreement shall be
     terminated in the manner provided above, whichever is the last to occur.

     TIME IS OF THE ESSENCE. Time is of the essence in the performance of this
     Agreement.

     WAIVE JURY. ALL PARTIES TO THIS AGREEMENT HEREBY WAIVE THE RIGHT TO ANY
