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 entire unpaid principal balance of this Note shall be payable on the earlier of: (i) December 31, 2021 or
(ii) the date on which Maker consummates an initial public offering of its securities (such earlier date, the “Maturity Date”). The principal balance may be prepaid at any time. Under no circumstances shall any individual,

2. Drawdown Requests. Maker and Payee agree that Maker may request, from time to time, up to Three Hundred Thousand Dollars ($300,000)

Payee shall fund each Drawdown Request no later than three (3) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns outstanding under this Note at any time may not exceed Three Hundred

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

4. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum
