          (five) business days of a written request from Borrower for an
          advance, Lender shall consider making such advance in accordance with
          the terms hereof. Lender shall note on Schedule A attached hereto the
          date and amount of each advance and the total of all unpaid advances
          shall be the outstanding balance of the Loan.
