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

3. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum
due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note. 

4. Events of Default. Each of the following shall constitute an event of default (each, an “Event of Default”):

	1 	 Payee will enter into an additional promissory note of up to $168,750 on the terms set forth herein depending
upon the extent to which the underwriter in the IPO exercises its over-allotment option.

(c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of
Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its
property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of sixty (60) consecutive days. 

5. Remedies. 
 (a) Upon
the occurrence of an Event of Default specified in Section 4(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts
payable hereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary
notwithstanding. 
 (b) Upon the occurrence of an Event of Default specified in Sections 4(b) or 4(c), the unpaid principal balance of this

principal balance of this Note, in whole or in part at the option of Payee, into shares of Class A Common Stock of Maker, par value $0.0001 per share (the “Class A Common Stock”), at a price of $10.00 per
shares of Class A Common Stock, as adjusted for any stock splits or combinations; provided that any such conversion may not occur until after the 60th day following the effective date of the registration statement filed in connection
with Maker’s IPO. As promptly as reasonably practicable after notice by Payee to Maker to convert the principal balance of this Note into shares of Class A Common Stock, which notice must be made at least five (5) business days prior

so issued, will be validly issued, fully paid and non-assessable and free from all taxes, liens and charges with respect to the issuance thereof and (ii) for so long as the Note is outstanding, Maker will
reserve from its authorized and unissued shares of Class A Common Stock sufficient shares in order to perform its obligations under this Note.

dishonor, protest, and notice of protest with regard to this Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or
future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or
extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof, or any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order
desired by Payee.
