NOW, THEREFORE, in
consideration of the representations, covenants and agreements contained herein, and certain other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to be legally bound, hereby agree as

LLC, a Delaware limited liability company, or its registered assigns or successors in interest (the
“Payee”), the Maker hereby promises to pay to the order of the Payee the principal sum of One Million
Dollars ($1,000,000) or such lesser amount as shall have been advanced by Payee to Maker and shall remain unpaid (or not otherwise
converted as provided for in Section 15) under this Note on the Maturity Date (as defined below) in lawful 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. Certain terms used herein but not defined herein
shall have the meaning given to such terms in the Agreement.


 


1.           Principal.
The entire unpaid principal balance of the Note (less any amounts converted as provided for in Section 15 hereof) shall be
payable on the date on which Maker consummates its Business Combination (the “Maturity Date”). 
All or any portion of the principal balance may be prepaid without penalty 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.           Drawdown
Requests. Maker and Payee agree that Maker may request, from time to time, up to One Million Dollars ($1,000,000) in aggregate

Request by Maker.

the occurrence of an Event of Default specified in Sections 5(b) or 5(c), the unpaid principal balance of this Note, and all other

 (a)          At
the Payee’s option upon notice to the Maker, at any time prior to payment in full of the principal balance of this Note,

duly endorsed, to Maker or such other address which Maker shall designate against delivery of the Warrants, (iii) Maker shall promptly
deliver a new duly executed Note to the Payee in the principal amount that remains outstanding, if any, after any such conversion
and (iv) in exchange for all or any portion of the surrendered Note, Maker shall deliver to Payee the Warrants, which shall bear
such legends as are required, in the opinion of counsel to Maker or by any other agreement between Maker and the Payee and applicable
state and federal securities laws.


 


(c)          The
Payee shall pay any and all issue and other taxes that may be payable with respect to any issue or delivery of the Warrants upon
conversion of this Note pursuant hereto; provided, however, that the Payee shall not be obligated to pay any transfer taxes resulting
from any transfer requested by the Payee in connection with any such conversion.


 


(d)          The
Warrants shall not be issued upon conversion of this Note unless such issuance and such conversion comply with all applicable provisions
of law.


 


16.         Registration
Rights.


 


(a)          Reference
is made to that certain Registration Rights Agreement between the Maker and the parties thereto, dated as of the date hereof (the
