               RATE").  The Permanent Default Rate shall be adjusted whenever a
               change in the Base Rate occurs, so that the Permanent Default
               Rate shall remain at all times four (4%) percent per annum above

               "PERMANENT DEFAULT RATE").  If the interest Rate shall be
               adjusted whenever a change in the Prime Rate occurs, so that the
               Permanent Default Rate shall remain at all times three percent
               (3%) per annum above the Prime Rate. Any such adjustment in the

               Permanent Default Rate shall be effective simultaneously with a
               change in the Prime Rate.

          7.   Section G. entitled "G. PREPAYMENT OF LOAN." on page eight of the
Note is hereby deleted in its entirety and the following is substituted in lieu
thereof:

               If the interest rate in effect under this Note is based upon the
               Prime Rate, the Borrower may prepay this Note in whole or in part
               at any time without penalty.  All such prepayments shall be
               applied on account of principal remaining unpaid and shall be
               accompanied by payment of unpaid late charges and accrued and
               unpaid interest, if any, thereon.  All partial prepayments of
               principal shall be credited to the unpaid principal of this Note
               in the inverse order of maturity and shall not affect the
               Borrower's obligation to make the regular installments required
               hereunder until this Note is fully paid.

               If the interest rate in effect under this Note is based upon the
               LIBOR Rate or Cost of Funds Rate, the Borrower may not prepay
               this Note except as set forth in this paragraph. Under no
               circumstances may there by a partial prepayment of this Note.
               The Borrower may prepay only the entire unpaid balance of this
               Note upon payment of such amounts, as determined by the Lender,
               in its sole and absolute discretion, as may be necessary to
               reimburse the Lender for any losses and expenses incurred by the
               Lender as a result of prepayment of this Note, including without
               limitation any losses (including loss of anticipated profits) and
               expenses incurred by reason of the liquidation or re-employment
               of deposits or other funds acquired by the Lender to fund or
               maintain this Note.  The Borrower hereby acknowledges that in
               reliance upon this agreement, the Lender has made certain
               commitments of funds upon the terms and conditions of this Note.
               In the event that this Note is accelerated for any reason
               whatsoever by the Lender, such payment of the Lender's losses and
               expenses shall be paid by the Borrower.

               In the event that the Loan shall be accelerated for any reason
               whatsoever, the prepayment fee in effect as of the date of such
               acceleration shall be paid.

          8.   The following is inserted after Section H to the Note:

               Section I.  Rate Elections. Conversion of Rate of Interest.
               Provided that no Event of Default shall have occurred and be
               continuing hereunder, the Borrower may, (i) at any time, if the
               interest rate in effect under this Note is based upon the Prime
               Rate and (ii) on the  last 


                                       6
<PAGE>   7



               Business Day of any Interest Period if the interest rate in
               effect under this Note is based upon the LIBOR Rate or Cost of
               Funds Rate, convert the interest rate hereunder to an interest
               rate based upon the Prime Rate, Cost of Funds Rate or LIBOR Rate.
               If the Borrower desires to so convert, it shall give Lender
               written notice two (2) days prior to the conversion date by
               written instructions, specifying the date of such conversion and,
               if conversion is to a LIBOR Rate or Cost of Funds Rate, the
               duration of the first Interest Period therefor.

               Failure to Convert or Continue.  If Borrower fails to notify
               Lender of its election to convert or continue an expiring
               interest rate based upon Cost of Funds Rate or LIBOR Rate on or
               prior to the end of the expiring Interest Period, such expiring
               interest rate shall, at the end of such Interest Period,
               automatically be based upon the Prime Rate.

          The Borrower and Lender hereby agree that the terms of the Mortgage
are hereby modified in accordance with the following:

          1.   Any and all references in the Mortgage to the term "Note" or
