WHEREAS, the Company desires to have such event of default under the Original Debenture waived by the Purchaser and further desires to extend the maturity date of the Original Debenture;

WHEREAS, the Company requires $350,000 of additional funding; and

WHEREAS, to affect such waivers and additional funding the Parties agree to the covenants and conditions set forth herein.

NOW, THEREFORE, in consideration of the foregoing recitals, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Parties agree as follows:

1.Amendment of Original Debenture. Concurrently with the execution and delivery of this Agreement by the Parties, the Original Debenture shall be amended as follows: 

a.The definition of the term “Maturity Date” shall be amended such that all references to “Maturity Date” in the Original Debenture shall mean the earlier of (i) within 48 hours of the closing of a Qualified Offering, (ii) within 48 hours of the date on which the Company’s Common Stock is listed on a “national securities exchange” as defined in the Exchange Act and (iii) September 1, 2022.

b.Section 3(b) of the Original Warrant is hereby amended and restated as follows: 

“b)Subsequent Equity Sales. If the Company or any Subsidiary thereof, as applicable, at any time while this Warrant is outstanding, shall sell, enter into an agreement to sell, or grant any option to purchase, or sell or grant any right to reprice, or otherwise dispose of or issue (or announce any offer, sale, grant or any option to purchase or other disposition) any Common Stock or Common Stock Equivalents, at an effective price per share less than the Exercise Price then in effect (such lower price, the “Base Share Price” and such issuances collectively, a “Dilutive Issuance”) (it being understood and agreed that if the holder of the Common Stock or Common Stock Equivalents so issued shall at any time, whether by operation of purchase price adjustments, reset provisions, floating conversion, exercise or exchange prices or otherwise, or due to warrants, options or rights per share which are issued in connection with such issuance, be entitled to receive shares of Common Stock at an effective price per share that is less than the Exercise Price, such issuance shall be deemed to have occurred for less than the Exercise Price on such date of the Dilutive Issuance at such effective price), then simultaneously with the consummation (or, if earlier, the announcement) of each Dilutive Issuance the Exercise Price shall be reduced and only reduced to equal the Base Share Price and the number of Warrant Shares issuable hereunder shall be increased such that the aggregate Exercise Price payable hereunder, after taking into account the decrease in the Exercise Price, shall be equal to the aggregate Exercise Price prior to such adjustment.  Notwithstanding the foregoing, no adjustments shall be made, paid or issued under this Section 3(b) (A) in respect of an Exempt Issuance or (B) after 24 months following the date on which the Company has listed its Common Stock on a “national securities exchange” as defined in the Exchange Act.  The Company shall notify the Holder, in writing, no later than the Trading Day following the issuance or deemed issuance of any Common Stock or Common Stock Equivalents subject to this Section 3(b), indicating therein the applicable issuance price, or applicable reset price, exchange price, conversion price and other pricing terms (such notice, the “Dilutive Issuance Notice”).  For purposes of clarification, whether or not the Company provides a Dilutive Issuance Notice pursuant to this Section 3(b), upon the occurrence of any Dilutive Issuance, the Holder is entitled to receive a number of Warrant Shares based upon the Base Share Price regardless of whether the Holder accurately refers to the Base Share Price in the Notice of Exercise. If the Company enters into a Variable Rate Transaction, the Company shall be deemed to have issued Common Stock or Common Stock Equivalents at the lowest possible price, conversion price or exercise price at which such securities may be issued, converted or exercised.” 

3.Purchase and Sale; Use of Proceeds. The Company agrees to sell, and the Purchaser agrees to purchase, an aggregate of $411,764 in principal amount of the New Debenture (inclusive of the original issue discount) for proceeds of $350,000. Accordingly, the Purchaser shall deliver to the Company, via wire transfer or a certified check, immediately available funds equal to $350,000 representing full payment to the Company of the proceeds for the New Debenture. The closing (“Closing”) of the purchase and sale of the New Debenture shall occur within two (2) Trading Days after the date hereof or at such other time as agreed by the Parties. 

4.Waiver of Events of Default. The Purchaser hereby agrees that effective at Closing, the Purchaser irrevocably waives all prior and current events of default on the Original Debenture. Nothing herein shall be construed as waiving any future events of default under the Original Debenture or any other documents or agreements following the date of Closing.

5.Additional Consideration for Waiver. As consideration for the waiver contemplated in Section 4 hereof and the purchase of the New Debenture contemplated in Section 3 hereof, on or prior to Closing, the Company agrees to issue to the Purchaser a New Warrant to purchase 388,236 shares of Common Stock. Such New Warrant shall be delivered at Closing with the New Debenture.

14.Venue.  The Parties irrevocably submit exclusively to the jurisdiction of the State of New York and the venue of New York County in any action brought by the Parties concerning this Agreement or the performance thereof. 

15.Choice of Law.  All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents shall be governed by and construed and enforced in accordance with the internal laws of the State of New York, without regard to the principles of conflicts of law thereof.  Each party agrees that all legal Proceedings concerning the interpretations, enforcement and defense of the transactions contemplated by this Agreement and any other Transaction Documents (whether brought against a party hereto or its respective affiliates, directors, officers, shareholders, partners, members, employees or agents) shall be commenced exclusively in the state or federal courts sitting in the City of New York.  Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, Borough of Manhattan for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein (including with respect to the enforcement of any of the Transaction Documents), and hereby irrevocably waives, and agrees not to assert in any Action or Proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such Action or Proceeding is improper or is an inconvenient venue for such Proceeding.  Each party hereby irrevocably waives personal service of process and consents to process being served in any such Action or Proceeding by mailing a copy thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof.  Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted by law.  If any party shall commence an Action or Proceeding to enforce any provisions of the Transaction Documents, then, in addition to the obligations of the Company under Section 13 related to indemnification, the prevailing party in such Action or Proceeding shall be reimbursed by the non-prevailing party for its reasonable and documented attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution of such Action or Proceeding.

16.Interpretation.  No provision of this Agreement shall be interpreted or construed against any Party because that Party or its legal representative drafted it. 

17.Rescission and Withdrawal Right.  Notwithstanding anything to the contrary contained in (and without limiting any similar provisions of) any of the other Transaction Documents, whenever Purchaser exercises a right, election, demand or option under a Transaction Document and the Company does not timely perform its related obligations within the periods therein provided, then Purchaser may rescind or withdraw, in its sole discretion from time to time upon written notice to the Company, any relevant notice, demand or election in whole or in part without prejudice to its future actions and rights; provided, however, that, in the case of a rescission of a conversion of the New Debenture or of an exercise of the New Warrant, Purchaser shall be required to return any shares of Common Stock subject to any such rescinded conversion notice concurrently with the return to Purchaser of the aggregate exercise price paid to the Company for such shares and the restoration of Purchaser’s right to acquire such shares (including, issuance of a replacement warrant certificate evidencing such restored right). 

18.Replacement of Securities.  If any certificate or instrument evidencing any Securities is mutilated, lost, stolen or destroyed, the Company shall issue or cause to be issued in exchange and substitution for and upon cancellation thereof (in the case of mutilation), or in lieu of and substitution therefor, a new certificate or instrument, but only upon receipt of evidence reasonably satisfactory to the Company of such loss, theft or destruction.  The applicant for a new certificate or instrument under such circumstances shall also pay any reasonable third-party costs (including customary indemnity) associated with the issuance of such replacement Securities. 

19.Remedies.  In addition to being entitled to exercise all rights provided herein or granted by law, including recovery of damages, each of Purchaser and the Company may be entitled to specific performance under the Transaction Documents.  The parties agree that monetary damages may not be adequate compensation for any loss incurred by reason of any breach of obligations contained in the Transaction Documents and hereby agree to waive and not to assert in any Action for specific performance of any such obligation the defense that a remedy at law would be adequate.   

20.Payment Set Aside.  To the extent that the Company makes a payment or payments to Purchaser pursuant to any Transaction Document or Purchaser enforces or exercises its rights thereunder, and such payment or payments or the proceeds of such enforcement or exercise or any part thereof are subsequently invalidated, declared to be fraudulent or preferential, set aside, recovered from, disgorged by or are required to be refunded, repaid or otherwise restored to the Company, a trustee, receiver or any other Person under any law (including, without limitation, any bankruptcy law, state or federal law, common law or equitable cause of action), then to the extent of any such restoration the obligation or part thereof originally intended to be satisfied shall be revived and continued in full force and effect as if such payment had not been made or such enforcement or setoff had not occurred. 

21.Usury.  To the extent it may lawfully do so, the Company hereby agrees not to insist upon or plead or in any manner whatsoever claim, and will resist any and all efforts to be compelled to take the benefit or advantage of, usury laws wherever enacted, now or at any time hereafter in force, in connection with any Action or Proceeding that may be brought by Purchaser in order to enforce any right or remedy under any Transaction Document.  Notwithstanding any provision to the contrary contained in any Transaction Document, it is expressly agreed and provided that the total liability of the Company under the Transaction Documents for payments in the nature of interest shall not exceed the maximum lawful rate authorized under applicable law (the “Maximum Rate”), and, without limiting the foregoing, in no event shall any rate of interest or default interest, or both of them, when aggregated with any other sums in the nature of interest that the Company may be obligated to pay under the Transaction Documents exceed such Maximum Rate.  It is agreed that if the maximum contract rate of interest  

6

allowed by law and applicable to the Transaction Documents is increased or decreased by statute or any official governmental action subsequent to the date hereof, the new maximum contract rate of interest allowed by law will be the Maximum Rate applicable to the Transaction Documents from the effective date thereof forward, unless such application is precluded by applicable law.  If under any circumstances whatsoever, interest in excess of the Maximum Rate is paid by the Company to Purchaser with respect to indebtedness evidenced by the Transaction Documents, such excess shall be applied by Purchaser to the unpaid principal balance of any such indebtedness or be refunded to the Company, the manner of handling such excess to be at such Purchaser’s election.

22.Liquidated Damages.  The Company’s obligations to pay any partial liquidated damages or other amounts owing under the Transaction Documents is a continuing obligation of the Company and shall not terminate until all unpaid partial liquidated damages and other amounts have been paid notwithstanding the fact that the instrument or security pursuant to which such partial liquidated damages or other amounts are due and payable shall have been canceled 

23.Counterparts.  This Agreement may be executed in two or more counterparts, each of which when so executed and delivered to the other party shall be deemed an original. The executed page(s) from each original may be joined together and attached to one such original and shall thereupon constitute one and the same instrument.  Such counterparts may be delivered by facsimile or other electronic transmission, which shall not impair the validity thereof. 

24.Acknowledgement. For the avoidance of doubt, to the extent that the Company does not satisfy the outstanding indebtedness by the Maturity Date, all of the default remedies in the SPA, the Original Debenture and any other related documentation will be available, without limitation, to the Purchaser.
