                                            time. Under no circumstances shall any individual, including but not limited to any officer,

                                            or liabilities of the Maker hereunder.
	 	 
	2.	Drawdown

                                            ($300,000.00) 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) June 30, 2022 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”).

                                            Thousand Dollars ($300,000.00). Once an amount is drawn down under this Note, it shall not
                                            be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts
                                            shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker.
                                            Notwithstanding the foregoing, 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, and then to the reduction of the unpaid principal balance
                                            of this Note.
	 	 
	3.	Interest.

                                            attorney’s fees, then to the payment in full of any late charges and finally to the
