Principal. The principal balance of this Promissory Note (this “Note”) shall be payable promptly after the date on which the Maker consummates an initial business combination (a “Business Combination”) with a target business (as described in its initial public offering prospectus dated August 5, 2021 (the “Prospectus”)). In the event that a Business Combination does not close on or prior to April 10, 2024, as such deadline may be further extended, this Note shall be deemed to be terminated and no amounts will thereafter be due from Maker to Payee under the terms hereof. The principal balance may not be prepaid without the consent of the Payee.

Conversion Rights. The Payee has the right, but not the obligation, to convert this Note, in whole or in part, into private units (the “Units”) of the Maker, as described in the Prospectus, by providing the Maker with written notice of its intention to convert this note at least one business day prior to the closing of a Business Combination. The number of Units to be received by the Payee in connection with such conversion shall be an amount determined by dividing (x) the sum of the outstanding principal amount payable to such Payee by (y) $10.00.

Fractional Shares. No fractional Units will be issued upon conversion of this Note. In lieu of any fractional Units to which Payee would otherwise be entitled, Maker will pay to Payee in cash the amount of the unconverted principal balance of this note that would otherwise be converted into such fractional share.

Effect of Conversion. If the Maker timely receives notice of the Payee’s intention to convert this note at least one business day prior to the closing of a Business Combination, this Note shall be deemed to be converted on the date the Business Combination closes. At its expense, the Maker will, as soon as practicable after receiving this Note for cancellation after the closing of a Business Combination (assuming receipt of timely notice of conversion), issue and deliver to Payee, at Payee’s address set forth on the signature page hereto or such other address requested by Payee, a certificate or certificates for the number of Units to which Payee is entitled upon such conversion (bearing such legends as are customary pursuant to applicable state and federal securities laws), including a check payable to Payee for any cash amounts payable as a result of any fractional shares as described herein.

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

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.

Events of Default. The following shall constitute an event of default (“Event of Default”):

Voluntary Liquidation, Etc. The commencement by Maker of a proceeding relating to its bankruptcy, insolvency, reorganization, rehabilitation or other similar action, or the consent by it to the appointment of, or taking possession by, a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) for 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.

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 similar law, for the appointing of a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) for Maker or for any substantial part of its property, or ordering the winding-up or liquidation of the affairs of Maker, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.
