1. Principal. The principal balance of this Note shall be repayable on the consummation of the Maker’s initial merger, share

offering. 
 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 attorneys’ 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. The following shall constitute Events of Default: 

(a) Failure to Make Required Payments. Failure by Maker to pay the principal of this Note within five (5) business days following
the date when due. 
 (b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under the Federal Bankruptcy Code,
as now constituted or hereafter amended, or any other applicable federal or state 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 the Federal Bankruptcy Code, as now or hereafter constituted, or any other applicable federal or state
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. 











 5. Remedies. 

(a) Upon the occurrence of an Event of Default specified in Section 4(a), Holder may, by written notice to Maker, declare this Note to be due
and payable, whereupon the 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 4(b) and 4(c), the unpaid principal balance of, 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 Holder.

 6. Conversion. Upon consummation of a Business Combination, the Holder shall have the option, but not the obligation, to convert
the principal balance of this Note, in whole or in part at the option of the Holder, into units (“Units’’) of the Maker at a price of $10.00 per Unit; provided, however, that the Holder shall be permitted to convert this Note
only if the shareholders of the Maker or the target business in any such Business Combination, whichever may be required in connection with such Business Combination, have approved the issuance of the Units to the Holder if such approval is
necessary under applicable law. The Units will be identical to the “private units” (as such term is defined in the Maker’s final prospectus for its initial public offering, dated February 3, 2021). As promptly as reasonably
practicable after notice by Holder to Maker to convert the principal balance of this Note, which must be made at least 24 hours prior to the consummation of the Business Combination, and after Holder’s surrender of this Note, Maker shall have
issued and delivered to Holder, without any charge to Holder, a certificate or certificates (issued in the name(s) requested by Holder) for the number of Units of Maker issuable upon the conversion of this Note. 

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 Holder 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 Holder. 
 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 Holder, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Holder with respect to the payment or other provisions of this Note, and
agree that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to them or affecting their liability hereunder.
