                              Loan in full by the final payment, payable
                              commencing on the date that is eight (8) months

                              provided that any remaining outstanding principal

                              to Section 10 hereof. If any such payment due date
                              is not a Business Day, then such payment may be
                              made on the next succeeding Business Day and such

                              of the Agreement and the Other Agreements, during

                              (which is not intended to be Bank's lowest or most
