1.            Payments of Principal and Interest.

(a) Payment of Principal and Interest. The principal balance of this Note and any accrued interest shall be paid to the Holder hereof on the Maturity Date. The Borrower may prematurely pay or prepay any outstanding principal balance or accrued interest to the Holder.

Whenever any amount expressed to be due by the terms of this Note is due on any day which is not a Business Day (as defined below), the same shall instead be due on the next succeeding day which is a Business Day and, in the case of any interest payment date which is not the date on which this Note is paid in full, the extension of the due date thereof shall not be taken into account for purposes of determining the amount of interest due on such date. For purposes of this Note, "Business Day" shall mean any day other than a Saturday, Sunday or a day on which commercial banks in the State of Delaware are authorized or required by law or executive order to remain closed. Notwithstanding the foregoing, all or any part of any amounts owing under the Note shall be convertible at the Holder’s discretion into common shares of Borrower’s stock at a 25% discount to the price per share at conversion.

Borrower hereby grants Holder a continuing security interest in the assets of Borrower to secure all obligations and performance of Borrower’s duties hereunder (collectively, the "Obligations"). Notwithstanding anything contained herein to the contrary, any rights granted to Holder pursuant to the security interest granted hereunder may only be enforced following prior written notice of a default of the Obligations to Borrower with a five (5) day opportunity for each party to cure such default.

3.            Defaults and Remedies.

(a) Events of Default. An "Event of Default" is: (i) default for five (5) days in payment of interest or Default Interest on this Note; (ii) default in payment of the principal amount of this Note when due; (iii) failure by the Borrower for five (5) days after notice to it to comply with any other material provision of this Note.
