This is a non-interest bearing Note.

The entire unpaid principal balance of this Note shall be due and payable upon the earlier of December 31, 2021 or the expiration of the underwriters’ 45-day option to purchase additional units to cover over-allotments, if any, in connection with Maker’s initial public offering of the Company’s securities.

If payment of this Note or any installment of this Note is not made when due, the entire indebtedness hereunder, at the option of Payee, shall immediately become due and payable, and Payee shall be entitled to pursue any or all remedies to which Payee is entitled hereunder, or at law or in equity.

This Note may be prepaid, in whole or in part, without penalty. This Note may not be changed, amended or modified except in a writing expressly intended for such purpose and executed by the party against whom enforcement of the change, amendment or modification is sought.
