Within ten (10) Business Days (as hereinafter defined) following each date that the Borrower shall receive pretax profits from any exercise of the options referred above in excess of the Profits Threshold, Borrower shall deliver a mandatory prepayment in reduction of the accrued interest and outstanding principal balance of this Note in an amount equal to 25% of the excess attributed to such exercise. Each prepayment, as provided herein, shall be applied first against accrued but unpaid interest under this Note and then in reduction of the outstanding principal amount hereof until the indebtedness of this Note is paid in full. "Business Day" shall mean any day on which NASDAQ is not authorized or required to close and trading of securities is permitted."
