corporation (the “Company”), having its principal place of business at 1825 NW Corporate Blvd., Suite 110 Boca Raton,

Recitals


 


WHEREAS,
pursuant to the Transaction Documents, Puritan Partners purchased a 12.5% Original Issue Discount Senior Secured Note in the principal
amount of $1,142,857.14 due March 2, 2023 (the “Note”) and was issued a common stock purchase warrant to purchase 22,857,143
shares of the common stock at $0.0001 exercise price (the “Warrants”);


 


WHEREAS,
Puritan Partners and Company are parties to the Transaction Documents and the parties desire to amend the respective Transaction
Documents in accordance with the terms of this Amendment.


 


NOW,
THEREFORE, in consideration of the following and other consideration, the receipt of which is hereby acknowledged, the parties agree
as follows:


 


	 	(a)	Qualified
    Offering. The definition of “Qualified Offering” set forth in Section 1.1 of the Securities Purchase Agreement (and as
    referenced in the other Transaction Documents) is deleted in its entirety and hereby replaced with the following:


 


“Qualified
Offering” means a debt (including convertible debt) or equity financing of either the Company or its Subsidiary’s securities
resulting in aggregate gross proceeds to the Company of at least $ 7,200,000. For purposes of clarity, to qualify as a Qualified Offering,
the gross proceeds must be raised in one (1) offering (which may have one or several closings) and the proceeds of multiple offerings
of securities with different terms will not be aggregated together.


 


	 	(b)	Monthly
    Redemption Date. The definition of “Monthly Redemption Date” set forth in Section 1 of the Note is deleted in its entirety
    and hereby replaced with the following:


 


“Monthly
Redemption Date” means the second of each month, commencing immediately upon October 2, 2022 and terminating upon the full
redemption of this Note.


 






    	 



     


    

 


(c)
Monthly Redemption Amount. The definition of “Monthly Redemption Amount” set forth in Section 1 of the Note is deleted in
its entirety and hereby replaced with the following:


 


“Monthly
Redemption Amount” means, as to a Monthly Redemption, one sixth of the original principal amount at 110% of such principal
amount, plus accrued but unpaid interest, liquidated damages and any other amounts then owing to the Holder in respect of this Note.


 


	 	(c)	In
    further consideration for extending by one month the straight-line amortization payment requirement under the Note, the Company agrees
    that (i) the number of shares underlying the Warrant shall be increased from 22,857,143 to 24,761,905 shares and (ii) upon the closing
    of Company’s offering being registered pursuant to the S-1 Registration Statement (Registration. No. 333-264339), the outstanding
    principal balance, along with any accrued fees or costs, will be repaid, in full pursuant to either the Optional Redemption provisions
    contained in Section 5(a) of the Note or the Mandatory Prepayment provisions contained in Section 5(d) of the Note, as the case may
    be.


 


Each
of the undersigned has caused this Agreement to be duly executed and delivered as of the date first written above.
