computed  on the basis of a 360 day year,  at an annual  rate equal to the prime
rate of interest (the "Prime Rate") adopted by M&I from time to time as the base
rate for interest rate determinations,  changing on each day that the Prime Rate
changes.  Interest shall be payable  monthly in arrears on the first day of each
month in each year,  commencing on June 1, 1994 and continuing  thereafter until
the principal is paid in full, with a final payment of interest due at maturity.

00/100  Dollars  ($100,000.00)  and shall be made on  telephonic  notice from an

paid or prepaid on this Note,  provided,  however,  that the aggregate amount of
loans  outstanding  hereunder  shall never exceed  $18,000,000.00.  All interest
under this Note shall be computed  for the actual  number of days elapsed on the
basis of a 360 day year.
