1.Section 1 of the Notes. Section 1 of the Notes is hereby deleted in its entirety and replaced with the following:

“1    Repayment. The entire then-outstanding and unpaid principal amount of this Note, together with any accrued but unpaid interest under this Note (the “Outstanding Amount”), shall be due and payable on the earlier to occur of (i) July 15, 2023 or (ii) within five (5) business days after the date on which the Company receives an aggregate of $20,000,000 from the consummation of one or more bona fide debt or equity financings, other capital investments, or capital contributions, whether from new or existing equity holders or debt holders (such applicable date, the “Maturity Date”). The Notes shall rank pari passu in right of payment with respect to each other Note, and all payments to each of the Holders under the Notes shall be made pro rata among the Holders based upon the aggregate unpaid principal amount of the Notes outstanding immediately prior to any such payment. All payments shall be made in lawful money of the United States of America at such place as the Holder hereof may from time to time designate in writing to the Company. Interest shall accrue on this Note but shall not be due and payable until the Holder’s written request for repayment after the Maturity Date.”

5.Counterparts; Electronic Delivery. This Amendment may be executed and delivered electronically and in counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument.
