RECITALS 

WHEREAS, the Maker sold and issued Promissory Note in the aggregate principal amount of $300,000 to the Payee on September 29,
2020 ( the “Note”); and 
 WHEREAS, the Maker and the Payee desire to amend the maturity date of the Note. 

NOW, THEREFORE, Maker and Payee agree as follows: 

1. Amendment. 

1.1 Section 1 is hereby deleted in its entirety and replaced with the following: 

“The principal balance of this Note shall be payable by the Maker on the earlier of: (i) May 31, 2021, or (ii) the date on
which Maker consummates an initial public offering of its securities (the “IPO”).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.” 

1.2 Section 3 is hereby deleted in its entirety and replaced with the following: 

“Maker and Payee agree that Maker may request up to Three Hundred Thousand Dollars ($300,000) for costs reasonably related to Maker’s
initial public offering of its securities. The principal of this Note may be drawn down from time to time prior to the earlier of: (i) May 31, 2021, 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 One Thousand Dollars ($1,000) unless agreed upon by
Maker and Payee. Payee shall fund each Drawdown Request no later than one (1) business day after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively under this Note is Three Hundred Thousand
Dollars ($300,000). No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.” 

2. No Further Modification. Nothing in this Amendment shall alter or modify any other provision of the Notes, except as
expressly provided herein. 
 3. Governing Law. This Amendment shall be governed by and construed in accordance with, the laws
of New York without regard to conflict of laws principles thereof.
