---------------------------        --------------         -----------
     (Maker)                          (Date)

1.   PROMISE TO PAY AND PAYMENT SCHEDULE.  The undersigned ("Maker", whether one
     or more) promises to pay to the order of Lincoln State Bank ("Lender") at
     2266 South 13th Street, Milwaukee 53215, Wisconsin, the sum of $250,000.00:

          a.   SINGLE PAYMENT.  In one payment on May 13, 2002.

2.   INTEREST CALCULATION.  If the amount of interest is not shown on line 4
     below, this Note bears interest on the unpaid principal balance before
     maturity:

          a.   VARIABLE RATE.  At the annual rate which is equal to the
               following Index Rate, plus 1.000 percentage points ("Note Rate"),
               and the Note Rate shall be adjusted as provided below.  The Index
               Rate is Prime Rate as published in the Wall Street Journal.

               The initial Note Rate is 5.750%.  An adjustment in the Note Rate
               will result in an increase or decrease in the amount of each
               payment of interest.

               In addition, Lender is authorized to change the amount of period
               payments if and to the extent necessary to pay in full all
               accrued interest owing on the Note.  The Maker agrees to pay any
               resulting payments or amounts.  The Note Rate shall be adjusted
               only on each scheduled payment date.

          b.   Interest is computed.  For the actual number of days principal is
               unpaid on the basis of 360 days a year.

          c.   Unpaid principal and interest bear interest after maturity until
               paid (whether by acceleration or lapse of time) at the rate of
               18.000% per year, computed on the same basis as the interest rate
               before maturity.

3.   INTEREST PAYMENT.  Interest is payable on April 13, 2002, and on the same
     day of each succeeding month thereafter.

4.   OTHER CHARGES.  If any payment (other than the final payment) is not made
     on or before the 15th day after its due date, Lender may collect a
     delinquency charge of 3.00% of the unpaid amount.

5.   PREPAYMENT.  Full or partial prepayment of this Note is permitted at any
     time without penalty.

6.   DEFAULT AND ENFORCEMENT.  Upon the occurrence of any one or more of the
     following events of default: (a) Maker fails to pay any amount when due
     under this Note or under any other instrument evidencing any indebtedness
     of Maker to Lender, (b) any representation or warrant made under this Note
     or information provided by Maker to Lender in connection with this Note is
     or was false or fraudulent in any material respect, (c) a material adverse
     change occurs in Maker's financial condition, (d) Maker fails to timely
     observe or perform any of the covenants, or duties contained in this Note,
     (e) any guarantee of Maker's obligations under this Note is revoked or
     becomes unenforceable for any reason, (f) Maker, Maker's spouse or a surety
     or guarantor of this Note dies or ceases to exist, (g) and event of default
     occurs under any agreement securing this Note, or (h) Lender deems itself
     insecure, then the unpaid balance shall, at the option of Lender, without
     notice, mature and become immediately payable.  The unpaid balance shall
     automatically mature and become immediately payable in the event any Maker,
     surety, indorser or guarantor becomes the subject of bankruptcy or other
     insolvency proceedings.  Lender's receipt of any payment on this Note after
     the occurrence of an event of default shall not constitute a waiver of the
     default or the Lender's rights and remedies upon such default.  To the
     extent not prohibited by law, Maker consents that venue for any legal
     proceeding relating to collection of this Note shall be, at Lender's option
     the county in which Lender has its principal office in this state, the
     county in which any Maker resides or the county in which this Note was
     executed.

                                   <Page 17>

7.   SECURITY.  This Note is secured by all existing and future security
     agreements and mortgages between Lender and Maker, between Lender and any
     indorser or guarantor of this Note, and between Lender and any other person
     providing collateral security for Maker's obligations, and payment may be
     accelerated according to any of them.  Unless a lien would be prohibited by
     law or would render a nontaxable account taxable, Maker grants to Lender a
     security interest and lien in any deposit account Maker may at any time
     have with Lender.  Lender may, at any time after an occurrence of an event
     of default, without notice or demand, set-off against any deposit balance
     or other money now or hereafter owed any Maker by Lender any amount unpaid
     under this Note.

8.   RIGHTS OF LENDER.  Without affecting liability of any Maker, indorser,
     surety, or guarantor, Lender may, without notice, accept partial payments,
     release or impair any collateral security for the payment of this Note or
     agree not to sue any party liable on it.  Lender may apply prepayments, if
     permitted, to such future installments as it elects.  Lender may without
     notice to Maker apply payments made by or for Maker to any obligation of
     Maker to Lender.  Without affecting the liability of any indorser, surety
     or guarantor, Lender may from time to time, without notice, renew or extend
     the time for payment.

9.   OBLIGATIONS AND AGREEMENTS OF MAKER.  The obligations under this Note of
     all Makers are joint and several.  All Makers, indorsers, sureties, and
     guarantors agree to pay all costs of collection before and after judgment,
     including reasonable attorneys' fees (including those incurred in
     successful defense or settlement of any counterclaim brought by Maker or
     incident to any action or proceeding involving Maker brought pursuant to
     the United States Bankruptcy Code) and waive presentment, protest, demand
     and notice of dishonor.  Maker agrees to indemnify and hold harmless
     Lender, its directors, officers, employees and agents, from and against any
     and all claims, damages, judgments, penalties, and expenses, including
     reasonable attorneys' fees, arising directly or indirectly from credit
     extended under this Note or the activities of Maker.  This indemnity shall
     survive payment of this Note.  Each Maker acknowledges that Lender has not
     made any representations or warranties with respect to, and that Lender
     does not assume any responsibility to Maker for, the collectability or
     enforceability of this Note or the financial condition of any Maker.  Each
     Maker has independently determined the collectability and enforceability of
     this Note.  Make authorizes Lender to disclose financial and other
     information about Maker to others.

10.  INTERPRETATION.  This Note is intended by Maker and Lender as a final
     expression of this Note and as a complete and exclusive statement of its
     terms, there being no conditions to the enforceability of this Note.  This
     Note may not be supplemented or modified except in writing.  This Note
     benefits Lender, its successors and assigns, and binds Maker and Maker's
     heirs, personal representative, successors and assigns.  The validity,

     of Wisconsin.  Invalidity or unenforceability of any provision of this Note
