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) February 28, 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

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 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) February 28, 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. 

4. 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. 

 5. Events of Default. The following shall constitute an event of default
(“Event of Default”): 
 (a) Failure to Make Required Payments. Failure by Maker to pay the principal
amount due pursuant to this Note within five (5) business days of the date specified above. 
 (b) Voluntary
Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver,
liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its
debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing. 
 (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 60 consecutive days. 
 6. Remedies. 

(a) Upon the occurrence of an Event of Default specified in Section 5(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 thereunder, 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 5(b) and 5(c), the unpaid principal balance of this Note,
and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee. 

7. Waivers. Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of
dishonor, protest, and notice of protest with regard to the 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, on any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee. 
 8.
Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to
the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or
modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting
Maker’s liability hereunder.

greater detail in the registration statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the
