Working Capital Promissory Note, dated as of September 8, 2023, by the Company in favor of the Purchaser

Principal Amount: Up to $500,000

(as set forth on the Schedule of Borrowings attached hereto as Exhibit A)

Principal. The outstanding principal balance of 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 (the “Maturity Date”) as described in the Maker’s initial public offering prospectus dated December 6, 2021 (the “Prospectus”). The principal balance may be prepaid at any time. Under no circumstances shall any individual, including but not limited to any officer, director, employee, partner, member or shareholder of Maker, be obligated personally for any obligations or liabilities of Maker hereunder. Payee understands that if a Business Combination is not consummated, this Note will not be repaid and all amounts owed hereunder will be forgiven except to the extent that Maker has sufficient funds available to it to repay any amounts outstanding hereunder.

Conversion at Option of the Payee. At any time and from time to time, at the option of the Payee, all or a portion of any unpaid and outstanding principal balance of this Note, subject to this Section 2, may be convertible into one or more private placement warrants of the Maker (the “Private Warrants”), with each $1.00 of unpaid and outstanding principal balance of this Note being convertible into one Private Warrant (a “Conversion”). Each Private Warrant, when and if transferred to Payee, will entitle the Payee to purchase one Class A ordinary share of the Maker, par value $0.0001 per share (each, an “Ordinary Share”), at an exercise price of $11.50 per Ordinary Share, subject to adjustment, and will otherwise have the terms set forth in that certain Warrant Agreement, attached as Exhibit B hereto, entered into by the Maker and Continental Stock Transfer & Trust Company on December 9, 2021 (the “IPO Closing Date”) at the consummation of the Maker’s initial public offering of the Maker’s units (the “IPO”). The Payee acknowledges and agrees that the Private Warrants, when and if transferred to Payee, will be subject to the terms of a letter agreement

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), transfer and cause to be issued and delivered 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 Private Warrants to which Payee is entitled upon such conversion (bearing such restrictive legends as are customary pursuant to applicable state and federal securities laws).

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

Drawdown Requests. The Maker and the Payee agree that the Maker may request up to Five Hundred Thousand Dollars ($500,000) in the aggregate for costs and expenses reasonably related to the Maker’s working capital needs prior to the consummation of the Business Combination. The principal amount of this Note may be drawn down from time to time prior to the Maturity Date, upon written request from the Maker to the 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 to by the Payee in its sole discretion. The Payee shall fund each Drawdown Request no later than three business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns outstanding under this Note at any one time may not exceed Five Hundred Thousand Dollars ($500,000). No fees, payments or other amounts shall be due to the Payee in connection with, or as a result of, any Drawdown Request by the Maker.

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 reduction of the unpaid principal balance of this Note.

Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary proceeding relating to its respective 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, as applicable, or for any substantial part of its respective property, or the making by the Maker of any assignment for the benefit of creditors, or the failure of Maker generally to pay its respective 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 respective 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.
