Interest on this Note shall commence accruing on the date hereof until payment in full of the principal sum, together with all accrued and unpaid interest and other amounts which may become due hereunder, has been made. Interest shall be computed on the basis of a 365-day year and actual days elapsed and shall be payable monthly, in arrears, on or before the first (1st) day of each month commencing in March 2015, based upon the outstanding principal balance except that, if any such date is not a Business Day, then such payment shall be due on the next succeeding Business Day (each, an “Payment Date”). Amounts due under this Note shall be payable by the Maker on each Payment Date in lawful money of the United States of America at the rate of 14% per annum. Principal shall be repayable on each Payment Date in an amount equal to the face amount on this Note divided by thirty six (36) months (or portion thereof) which equals a monthly principal amortization payment of Fifty Five Thousand Five Hundred Fifty Five Dollars and 56/100 ($55,555.56) on each Payment Date. The entire unpaid principal balance plus all accrued interest shall be due and payable on the third anniversary of the date hereof (the “Maturity Date”) upon presentment of this Note.

The Maker may prepay the loan in whole or in part at any time without payment of any prepayment penalty.

If there is a default in the payment of any of the sums mentioned herein or in the performance (whether monetary or not) of any of the agreements contained herein or in the Security Agreement or the Loan Agreement, or in any other agreement or loan document executed in conjunction with the Note, then the entire principal sum, plus all accrued but unpaid interest, shall be at the option of the Holder hereof at once due and payable without notice, time being of the essence; and said principal sum shall bear interest from the date of default at the highest rate allowable under the laws of the State of Florida. Failure to exercise this option shall not constitute a waiver of the right to exercise the same in the event of a subsequent default. Each person liable hereon whether Maker or Guarantor, hereby waives presentment, protest, notice of protest and notice of dishonor and agrees to pay all costs, including reasonable attorneys’ fees, including all appeals, if any, whether suit be brought or not if, after maturity of this Note or default hereunder, counsel shall be employed to collect this Note or to protect the security of said loan or enforce the provisions of this Note or any agreements referenced herein.

Should any interest or other charges paid by the Maker or parties liable for the payment of this Note or any other document delivered in connection with said loan result in the computation or earning of interest in excess of the maximum legal interest which is legally permitted under the laws of the State of Florida, then any and all such excess shall be and the same is hereby waived by payee and any holder hereof and any and all such excess shall be void automatically ab initio from the date of this Note and as of the date of the payment credited against and in reduction of the principal of said excess which exceeds the balance due under this indebtedness shall be paid by the Holder hereof to the Maker and parties liable for the payment of this Note.
