money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by
check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may
from time to time designate by written notice in accordance with the provisions of this Note.


 


1.             Principal.
The principal balance of this Note shall be payable by the Maker on the earlier of: (i) September 30, 2022 or (ii) the date
on which Maker consummates an initial public offering of its securities. The principal balance may be prepaid at any time. Under
no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker,
be obligated personally for any obligations or liabilities of the Maker hereunder.


 


2.             Interest.
No interest shall accrue on the unpaid principal balance of this Note.


 


3.             Drawdown
Requests. Maker and Payee agree that Maker may request up to Four Hundred Thousand Dollars ($400,000) for costs reasonably
related to Maker’s initial public offering (the “IPO”) of its securities. The principal of this Note may
be drawn down from time to time prior to the earlier of: (i) September 30, 2022 or (ii) the date on which Maker consummates an
initial public offering of its securities, upon written request from Maker to Payee (each, a “Drawdown Request”). Each
Drawdown Request must state the amount to be drawn down, and must not be an amount less than Ten Thousand Dollars ($10,000) unless

Dollars ($400,000). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if
prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by
Maker.
