Capitalized terms not defined in this Note shall have the meaning ascribed to them in the Securities Purchase Agreement, dated as of __________________, among the Company and the purchasers party thereto (the “Purchase Agreement”).

Certain capitalized terms are defined in Section 8 hereof.

1. Interest Rate. This Note bears an annualized interest rate of ten percent (10%) payable upon maturity or a conversion of the Note and shall begin accruing on such date as the initial funds shall have been distributed pursuant to the terms of the Escrow Agreement. All interest accruing hereunder shall be paid-in-kind on the last day of each calendar month by capitalizing and adding such amount to the outstanding principal balance of this Note, which amount shall thereafter constitute principal hereunder.

2. Maturity Date. The entire principal amount of this Note shall be due and payable on April 1^st, 2023 (such date, the “Maturity Date”).

3. Conversion.

(a) Mandatory Conversion.

(i) This Note shall automatically convert into shares of Common Stock or Units, as provided herein, immediately upon the earliest to occur of (a) the listing of the Common Stock on NASDAQ (the “Uplist”), and (b) a Subsequent Qualified Financing Date, at a price per share equal to the lesser of (i) $0.25 and (ii) 70% (A) in the case of the Uplist, the price of the Common Stock or Units (as defined below) in the offering relating to the Uplist, or (B) in the case of a Subsequent Qualified Financing, (x) the conversion price of the Common Stock, if such Subsequent Qualified Offering involves the issuance of convertible Notes, or (y) the price of the Common Stock or Units (as defined below) in such Subsequent Qualified Financing, if such Subsequent Qualified Financing involves the issuance of Common Stock or Units. For purposes of this Note, a “Unit” shall mean the combination of Common Stock and warrants to purchase Common Stock offered by the Company in any financing occurring simultaneously with the Uplist (“Simultaneous Uplist Unit Offering”). For purposes of this Note, “Subsequent Qualified Financing Date” shall mean the date on which the Company shall have received proceeds in excess of $5,000,000.00 from a transaction or series of related transactions occurring prior to the Maturity Date, including, but not limited to, equity financings, business combinations or other issuances of the Company’s equity securities (not including the transactions contemplated by the Purchase Agreement).

(ii) In connection with any conversion of this Note pursuant to this Section 3(a), the Company will deliver a dated and signed notice of conversion (the “Company Notice of Conversion”), the form of which is attached to this Note as Exhibit A-1, notifying the Payee of the conversion.

(b) Voluntary Conversion.

(i) The Holder shall have the right (subject to the conversion limitations set forth in Section 3(c)(viii) hereof) from time following the date hereof to convert all or any part of the outstanding and unpaid principal and interest under this Note into fully paid and non- assessable shares of Common Stock, as such Common Stock exists on the date hereof, or any shares of capital stock or other securities of the Company into which such Common Stock shall hereafter be changed or reclassified at the Voluntary Conversion Price (as defined below).

(ii) If this Note is being converted pursuant to this Section 3(b), this Note shall be convertible into a number of shares of Common Stock equal to the quotient of (I) the outstanding aggregate principal amount of the Note plus accrued but unpaid interest thereon, divided by (II) $0.25 (the “Voluntary Conversion Price”).

(iii) In connection with any conversion of this Note pursuant to this Section 3(b), the Holder will deliver to the Company a dated and signed notice of conversion (the “Holder Notice of Conversion”), the form of which is attached to this Note as Exhibit A-2, notifying the Company of the proposed conversion. If no date of conversion is specified in a Holder Notice of Conversion, the date of conversion shall be the date that such Holder Notice of Conversion is deemed delivered hereunder.

(i) No fractional shares shall be issued upon a conversion and all fractional shares shall be rounded up to the nearest whole share of Common Stock.

(ii) As soon as possible after a conversion has been effected (but in any event within five (5) Trading Days), the Company shall deliver to the Payee a certificate or certificates representing the shares and warrants (in the case of any conversion of this Note into Units) issuable by reason of such conversion in such name or names and such denomination or denominations as the then Payee has specified in writing to the Company, or if not so specified, in one (1) certificate and in the name of the then Payee.

(iii) In lieu of delivering physical certificates representing the Common Stock issuable upon conversion, provided the Company is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer (“FAST”) program, upon written request of the then Payee and its compliance with the provisions contained this Section 3, the Company shall use its commercially reasonable best efforts to cause its transfer agent to electronically transmit the Common Stock issuable upon conversion to the Payee by crediting the account of such Payee’s broker with DTC through its Deposit Withdrawal At Custodian (“DWAC”) system.

(iv) The issuance of Common Stock or Units upon conversion of this Note shall be made without charge to the then Payee in respect thereof or other cost incurred by the Company in connection with such conversion. Upon conversion of this Note, the Company shall take all such actions as are necessary to ensure that the Common Stock or warrants (in the case of any conversion of this Note into Units) issuable upon conversion of the Note shall be validly authorized and available for issue, fully paid and nonassessable.

(v) The Company shall not close its books against the transfer of this Note in any manner which interferes with the timely conversion of this Note. The Company shall assist and cooperate with any holder of this Note required to make any governmental filings or obtain any governmental approval prior to or in connection with the conversion of this Note (including, without limitation, making any filings required to be made by the Company).

(vi) The Company shall at all times reserve and keep available out of its authorized but unissued shares of Common Stock, solely for the purpose of issuance upon conversion hereunder, such number of shares of Common Stock issuable upon conversion of this Note. All shares of Common Stock issuable upon conversion of this Note shall, when issued, be duly and validly issued, fully paid and nonassessable and free from all taxes, liens and charges other than those occurring as a result of the actions or non-actions of the holder. The Company shall take all such actions as may be reasonably necessary to assure that all such shares of Common Stock may be so issued without violation of any applicable law or governmental regulation or any requirements of the Trading Market for the Common Stock.

(vii) The shares of Common Stock or shares of Common Stock underlying warrants, if any (in the case of any conversion of this Note into Units) issuable upon conversion of this Note may not be sold or transferred unless (a) such shares or shares underlying the warrants are sold pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “1933 Act”) or (b) the Company or its transfer agent shall have been furnished with an opinion of counsel reasonably acceptable to the Company to the effect that the shares or shares underlying such warrants to be sold or transferred may be sold or transferred pursuant to an exemption from such registration or (c) such shares or warrants are sold or transferred pursuant to Rule 144 of the 1933 Act, or other applicable exemption. Until such time as the shares of Common Stock or shares underlying the warrants have been registered under the 1933 Act or otherwise may be sold pursuant to Rule 144 or other applicable exemption without any restriction including as to the amount of securities as of a particular date that can then be immediately sold, each certificate for shares of Common Stock or shares underlying warrants that is not included in an effective registration statement or that have not been sold pursuant to an effective registration statement or an exemption that permits removal of the legend, shall bear a legend substantially in the following form, as appropriate:

“NEITHER THE ISSUANCE AND SALE OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE NOR THE SECURITIES INTO WHICH THESE SECURITIES ARE EXERCISABLE HAVE BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE OFFERED FOR SALE, SOLD, TRANSFERRED OR ASSIGNED (I) IN THE ABSENCE OF (A) AN EFFECTIVE REGISTRATION STATEMENT FOR THE SECURITIES UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR (B) AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO THE COMPANY, THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT OR (II) UNLESS SOLD PURSUANT TO RULE 144, RULE 144A, REGULATION S UNDER SAID ACT, OR OTHER APPLICABLE EXEMPTION.”

(viii) The Company shall not effect any conversion of principal and/or interest of this Note, and a Holder shall not have the right to the conversion of any principal and/or interest of this Note, to the extent that after giving effect to the conversion set forth on the applicable Notice of Conversion, the Holder (together with the Holder’s affiliates, and any persons acting as a group together with the Holder or any of the Holder’s affiliates) would beneficially own in excess of the Beneficial Ownership Limitation (as defined below). For purposes of the foregoing sentence, the number of shares of Common Stock beneficially owned by the Holder and its affiliates shall include the number of shares of Common Stock issuable upon conversion of this Note with respect to which such determination is being made, but shall exclude the number of shares of Common Stock which are issuable upon (i) conversion of the remaining, unconverted principal amount of this Note beneficially owned by the Holder or any of its affiliates and (ii) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or any of its affiliates. Except as set forth in the preceding sentence, for purposes of this Section 3(c)(viii), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations promulgated thereunder. Upon the written or oral request of a Holder, the Company shall within two Business Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding. In any case, the number of outstanding shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Note, by the Holder or its affiliates since the date as of which such number of outstanding shares of Common Stock was reported. The “Beneficial Ownership Limitation” shall be 4.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock issuable upon conversion of this Note held by the Holder. The Holder, upon not less than 61 days’ prior notice to the Company, may increase or decrease the Beneficial Ownership Limitation provisions of this Section 3(c)(viii), provided that the Beneficial Ownership Limitation in no event exceeds 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the issuance of shares of Common Stock upon conversion of this Note held by the Holder and the Beneficial Ownership Limitation provisions of this Section 3(c)(viii), shall continue to apply. Any such increase or decrease will not be effective until the 61st day after such notice is delivered to the Company. The Beneficial Ownership Limitation provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 3(c)(viii), to correct this paragraph (or any portion hereof) which may be defective or inconsistent with the intended Beneficial Ownership Limitation contained herein or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall apply to a successor holder of this Note.

4. Method of Payments.

(i) Payment. So long as the Payee or any of its registered assigns shall be the holder of this Note, and if this Note has not previously been converted, the Company will pay all outstanding principal and accrued but unpaid interest becoming due on this Note held by the Payee or any of its registered assigns not later than 1:00 p.m. New York time, on the date such payment is due hereunder, in immediately available funds, in accordance with the payment instructions attached hereto on Schedule 4(i), without the presentation or surrender of this Note or the making of any notation thereon.

The Company will afford the benefits of this Section to the Payee and to each other Person holding this Note.

(ii) Transfer and Exchange. Upon surrender of any Note for registration of transfer or for exchange to the Company, in accordance with the terms hereof, at its principal office, the Company at its sole expense will execute and deliver in exchange therefor a new Note or Notes, as the case may be, as requested by the holder or transferee, which aggregate principal amount is equal to the unpaid principal amount of such Note, registered as such holder or transferee may request; provided that this Note may not be transferred by Payee to any Person other than Payee’s affiliates without the prior written consent of the Company (which consent shall not be unreasonably withheld or delayed). The issuance of new Notes shall be made without charge to the holder(s) of the surrendered Note for any issuance tax in respect thereof or other cost incurred by the Company in connection with such issuance, provided that each Noteholder shall pay any transfer taxes associated therewith. The Company shall be entitled to regard the registered holder of this Note as the holder of the Note so registered for all purposes until the Company or its agent, as applicable, is required to record a transfer of this Note on its register.

(iii) Replacement. Upon receipt of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of any Note and, in the case of any such loss, theft or destruction of any Note, upon receipt of an indemnity reasonably satisfactory to the Company or, in the case of any such mutilation, upon the surrender and cancellation of such Note, the Company, at its expense, will execute and deliver, in lieu thereof, a new Note of like tenor and dated the date of such lost, stolen, destroyed or mutilated Note.
