(g) Nothing contained in this Note shall be construed to permit MDFC to charge or receive at any time interest, fees or other charges in excess of the amounts which MDFC is legally entitled to charge and receive under any law to which such interest, fees or charges are subject. In no contingency or event whatsoever shall the compensation payable to MDFC by the Maker, howsoever characterized or computed, hereunder, exceed the highest rate permissible under any law to which such compensation is subject. There is no intention that MDFC shall contract for, charge or receive compensation in excess of the highest lawful rate, and, in the event it should be determined that MDFC has contracted for any rate of interest in excess of the highest lawful rate, then ipso facto such rate shall be reduced to the highest lawful rate so that no amounts shall be charged or received which are in excess thereof, and, in the event it should be determined that any excess over such highest lawful rate has been charged or received, MDFC shall promptly refund such excess to the Maker; provided, however, that, if lawful, any such excess shall be paid by the Maker to MDFC as additional interest (accruing at a rate equal to the maximum legal rate minus the rate provided for hereunder) during any subsequent period when regular interest is accruing hereunder at less than the maximum legal rate.

(h) Time is of the essence as to all times and dates set forth in or applicable to this Note with respect to all payments to be made by or on behalf of the Maker hereunder.

(i) No failure on the part of MDFC to exercise, and no delay in exercising, any right hereunder shall operate as a waiver thereof or preclude any other or further exercise thereof or the exercise of any other right. The remedies herein provided are cumulative and not exclusive of any remedies provided by law.
