     Borrower further agrees that, as expressly modified hereby, all terms and
     provisions of the Loan Documents shall be and remain in full force and
     effect.

          6.   NO DEFAULT, DEFENSES, COUNTERCLAIMS, ETC.  Borrower hereby

          7.   COSTS AND EXPENSES.  Borrower agrees to pay all costs incurred
     in connection with the execution and consummation of this Agreement,
     including but not limited to, all recording costs, the premium for such
     endorsements to the policies of title insurance insuring the Deed of 
     Trust as may be required by Lender with respect to this Agreement, and
     the reasonable fees and actual expenses of Lender's counsel.  Borrower
     further covenants and agrees to deliver or cause to be delivered such
     evidence of existence, capacity, authorization, qualification, or
     enforceability of its obligations as Lender may require.

          8.   LIMITATION ON INTEREST.  All agreements between Borrower and
     Lender, whether now existing or hereafter arising and whether written or
     oral, are hereby expressly limited so that in no contingency, whether by
     reason of acceleration of the maturity of the Notes, or otherwise, shall
     the interest contracted for, charged, received, paid or agreed to be paid
     to the holder of the Notes exceed the maximum amount permissible under
     applicable law.  If, from any circumstance whatsoever, interest would
     otherwise be payable to the holder of the Notes in excess of the maximum
     lawful amount, the interest payable to the holder of the Notes shall be
     reduced to the maximum amount permitted by applicable law; and if from
     any circumstance the holder of the Notes shall ever receive anything of
     value deemed interest by applicable law in excess of the maximum amount
     allowed by law, an amount equal to any excessive interest shall be
     applied to the reduction of the principal amount owing under the Notes,
     and not to the payment of interest, or if such excessive interest exceeds
     such unpaid balance of principal of the Notes, such excess shall be
     refunded to Borrower.  All interest paid or agreed to be paid to the
     holder of the Notes, shall, to the extent permitted by applicable law, be
     amortized, prorated, allocated and spread throughout the full term of the
     Notes (including the period of any renewal or extension thereof) so that
     the interest on the Notes shall not exceed the maximum amount permitted
     by applicable law.  This paragraph shall control all agreements between
     Borrower and the holder of the Notes.

     

          EXECUTED by the parties hereto as of the date and year first above
     written.
