     3.   The Parties also desire to amend the Loan Documents to extend the
maturity date of the Loan to November 30, 2000.

the Note and the Loan Documents. From and after the date hereof, Obligors are

as amended by the Loan Documents Amendment and this Amendment.

     4.   Maturity Date. The Note is hereby amended and modified to provide that

          ------------------------------
each and every warranty and representation set forth in all Loan Documents. The

which may be occurring or be granted or entered into hereunder or otherwise)
with respect to nonpayment of the Loan or any portion thereof, or with respect
to matters involving security for the Loan, or with respect to any other matter
relating to the Loan, shall require or imply any future extension, indulgence,
waiver, consent or agreement by Bank. Bank has made no agreement, and is in no
way obligated, to grant any future extension, indulgence, waiver or consent with
