PROMISE TO PAY. Softech, Inc. ("Borrower") promises to pay to Greenleaf Capital,
Inc. ("Lender"), or order, in lawful money of the United States of America, the
principal amount of Three Million &00/100 Dollars ($3,000,000.00) or so much as
may be outstanding, together with interest on the unpaid outstanding principal
balance of each advance. Interest shall be calculated from the date of each
advance until repayment of each advance.

PAYMENT The principal of and interest on this note shall be paid in installments
        beginning on the 12th day of each succeeding month under which there is
        an outstanding principal amount due until June 12, 2004, at which time
        the remaining balance of principal and interest shall be paid in full.
        Each installment shall be in an amount equal to a sum that allows for
        the principal to be repaid over a 5 year amortization period plus
        interest accrued at the above rate on the average outstanding principal
        outstanding for the previous 30 day period. The annual interest rate for
        this Note is computed on a 365/360 basis; that is, by applying the ratio
        of the annual interest rate over a year of 360 days, multiplied by the
        outstanding principal balance, multiplied by the actual number of days
        the principal balance is outstanding. Borrower will pay Lender at
        Lender's address shown above or at such other place as Lender may
        designate in writing.

Notwithstanding the above, this Agreement terminates on June 1, 2002 at which
time all monies owed including interest through that date are due and payable
unless specifically extended through written agreement between the parties.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change from
time to time based on changes in the rate at which Lender borrows from the
Huntington National Bank (the "Huntington Rate"). The rate currently is 8.650%
per annum. The interest rate to be applied to the unpaid principal balance of
this Note will be at a rate of 3.000 percentage points over the Huntington Rate,
resulting in an initial rate of 11.650% per annum. NOTICE: Under no
circumstances will the interest rate on this Note be more than the maximum rate
allowed by applicable law.


<PAGE>

PREPAYMENT. Borrower may pay without penalty all or a portion of the amount owed
earlier than it is due. Early payments will not, unless agreed to by Lender in
writing, relieve Borrower of Borrower's obligation to continue to make payments
of accrued unpaid interest. However, early payments will reduce the principal
balance due.

LATE CHARGE. If a payment is 11 days or more late Borrower will be charged
5.000% of the regularly scheduled payment.
INTEREST AFTER DEFAULT. Upon default, including failure to pay upon final
maturity, Lender, at its option, may, if permitted under applicable law,
increase the variable interest rate on this Note to 4.000 percentage points over
the Huntington rate. The interest rate will not exceed the maximum rate
permitted by applicable law.

DEFAULT. Each of the following shall constitute an event of default under this
         Note:

         PAYMENT DEFAULT.  Borrower fails to make any payment when due under
         this Note.

         OTHER DEFAULTS. Borrower fails to comply with or to perform any other
         term, obligation, covenant or condition contained in this Note 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.

         FALSE STATEMENTS. Any warranty, representation or statement made or
         furnished to Lender by Borrower or on Borrower's behalf under this 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 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.

         CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure of
         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 a 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, it its sole discretion, as being an
         adequate reserve or bond for the dispute.
