The execution, delivery and performance of the this Agreement and the consummation of the transactions contemplated thereby will not result in any such violation or be in conflict with or constitute, with or without the passage of time and giving of notice, either a default under any such provision, instrument, judgment, order, writ, decree or contract or an event that results in the suspension, revocation, impairment, forfeiture or nonrenewal of any material permit, license, authorization or approval applicable to the Company, its business or operations or any of its assets or properties, except for such results which would not reasonably be expected to be material to the Company.

5.5    Offering. Subject in part to the accuracy of each Purchaser’s representations set forth in Section 6 of this Agreement, the offer, sale and issuance of the Notes as contemplated by this Agreement are exempt from the registration requirements of the Securities Act and will not result in a violation of the qualification or registration requirements of the any applicable state securities laws.

5.6    Valid Issuance of Securities. The shares of Common Stock issuable upon conversion of the Notes, when issued, sold and delivered in accordance with the terms of this Agreement and the Notes, will be duly and validly issued, fully paid, and nonassessable.

6.    Representations and Warranties of the Purchasers. In connection with the transactions contemplated by this Agreement, each Purchaser, severally and not jointly, hereby represents and warrants to the Company as follows:

6.1    Authorization. Each Purchaser has full power and authority (and, if such Purchaser is an individual, the capacity) to enter into this Agreement and to perform all obligations required to be performed by it hereunder. This Agreement, when executed and delivered by each Purchaser, will constitute such Purchaser’s valid and legally binding obligation, enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, and (b) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

6.2    Purchase Entirely for Own Account. Each Purchaser acknowledges that this Agreement is made with such Purchaser in reliance upon such Purchaser’s representation to the Company, which such Purchaser confirms by executing this Agreement, that the Notes and any shares of Common Stock issuable upon conversion of the Notes (collectively, the “Securities”) will be acquired for investment for such Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that such Purchaser has no present intention of selling, granting any participation in, or otherwise distributing the same. By executing this Agreement, each Purchaser further represents that such Purchaser does not have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to the Securities.

6.3    Disclosure of Information; Non-Reliance. Each Purchaser acknowledges that it has received all the information it considers necessary or appropriate to enable it to make an informed decision concerning an investment in the Securities. Each Purchaser further represents that it has had an opportunity to ask questions and receive answers from the Company regarding the terms and conditions of the offering of the Securities. Each Purchaser confirms that the Company has not given any guarantee or representation as to the potential success, return, effect or benefit (either legal, regulatory, tax, financial, accounting or otherwise) of an investment in the Securities. In deciding to purchase the Securities, each Purchaser is not relying on the advice or recommendations of the Company and such Purchaser has made its own independent decision that the investment in the Securities is suitable and appropriate for such Purchaser. Each Purchaser understands that no federal or state agency has passed upon the merits or risks of an investment in the Securities or made any finding or determination concerning the fairness or advisability of this investment.

6.4    Investment Experience. Each Purchaser is an investor in securities of companies in the development stage and acknowledges that it is able to bear the economic risk of its investment and has such knowledge and experience in financial or business matters that it is capable of evaluating the merits and risks of the investment in the Securities.

6.5    Accredited Investor. Each Purchaser is an “accredited investor” within the meaning of Rule 501 of Regulation D promulgated under the Securities Act. Each Purchaser agrees to furnish any additional information requested by the Company to assure compliance with applicable U.S. federal and state securities laws in connection with the purchase and sale of the Securities.

6.6    Restricted Securities. Each Purchaser understands that the Securities have not been registered under the Securities Act or any state securities laws, by reason of specific exemptions under the provisions thereof which depend upon, among other things, the bona fide nature of the investment intent and the accuracy of each Purchaser’s representations as expressed herein. Each Purchaser understands that the Securities are “restricted securities” under U.S. federal and applicable state securities laws and that, pursuant to these laws, such Purchaser must hold the Securities indefinitely unless they are registered with the Securities and Exchange Commission (“SEC”) and registered or qualified by state authorities, or an exemption from such registration and qualification requirements is available. Each Purchaser acknowledges that the Company has no obligation to register or qualify the Securities for resale except as set forth in Section 7, and further acknowledges that, if an exemption from registration or qualification is available, it may be conditioned on various requirements including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of such Purchaser’s control, and which the Company is under no obligation, and may not be able, to satisfy.

6.7    No Public Market. Each Purchaser understands that no public market now exists for the Notes and that the Company has made no assurances that a public market will ever exist for the Notes.

6.8    No General Solicitation. Each Purchaser, and its officers, directors, employees, agents, stockholders or partners have not either directly or indirectly, including through a broker or finder solicited offers for or offered or sold the Securities by means of any form of general solicitation or general advertising within the meaning of Rule 502 of Regulation D under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act. Each Purchaser acknowledges that neither the Company nor any other Person offered to sell the Securities to it by means of any form of general solicitation or advertising within the meaning of Rule 502 of Regulation D under the Securities Act or in any manner involving a public offering within the meaning of Section 4(a)(2) of the Securities Act.

6.9    Foreign Investors. If a Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended), such Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of this Agreement, including (a) the legal requirements within its jurisdiction for the purchase of the Securities; (b) any foreign exchange restrictions applicable to such purchase; (c) any governmental or other consents that may need to be obtained; and (d) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, conversion, redemption, sale, or transfer of the Securities. Each such Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of such Purchaser’s jurisdiction. Each such Purchaser acknowledges that the Company has taken no action in foreign jurisdictions with respect to the Securities.

7.    Registration Rights.

7.1    Registration Statement. 6.107.1The Company shall, on or before April 30, 2023, file with the SEC (at its sole cost and expense) a registration statement on Form S-1 or, if eligible, Form S-3 (the “Registration Statement”) to register the resale of the Common Stock issuable pursuant to the Notes and the May 2022 Notes (collectively, the “Registrable Securities”), and it shall use its reasonable best efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof. Unless otherwise agreed to in writing by the Purchasers, no Person that is a Purchaser of the Notes or that purchased any of the May 2022 Notes shall be identified as a statutory underwriter in the Registration Statement unless requested or required by statute, regulation or exchange rules; provided, that if the SEC requests that such Persons be identified as a statutory underwriter in the Registration Statement, the Company will give such Persons notice and an opportunity to withdraw from the Registration Statement. Notwithstanding the foregoing, if the SEC prevents the Company from including any or all of the Registrable Securities proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act or otherwise, such Registration Statement shall register for resale such number of Registrable Securities which is equal to the maximum number of Registrable Securities as is permitted by the SEC. In such event, the number of Registrable Securities to be registered for each Purchaser and Person that purchased any of the May 2022 Notes that is named in the Registration Statement shall be reduced pro rata among all such Persons, and as promptly as practicable after being permitted to register additional shares of Common Stock under Rule 415 under the Securities Act, the Company shall file a new Registration Statement to register such Registrable Securities not included in the initial Registration Statement and cause such Registration Statement to become effective as promptly as practicable. The Company agrees to cause such Registration Statement, or another shelf registration statement that includes the Registrable Securities, to remain effective until the earliest of (i) the second anniversary of the relevant Closing, or (ii) the date on which such Purchaser ceases to hold any Registrable Securities. Each Purchaser agrees to disclose its beneficial ownership, as determined in accordance with Rule 13d-3 of the Exchange Act, to the Company upon request to assist the Company in making the determination described above.

7.2    Delay or Suspension of Registration. Notwithstanding anything to the contrary contained herein, the Company may, upon written notice to the Purchasers, delay or postpone filing of such Registration Statement, and from time to time require Purchaser not to sell under the Registration Statement or suspend the use of any such Registration Statement if it determines that in order for the Registration Statement to not contain a material misstatement or material omission, an amendment or supplement thereto would be needed, or if such filing or use would reasonably be expected to materially and adversely affect a bona fide business or financing transaction being pursued by the Company or would require premature disclosure of information that would reasonably be expected to materially and adversely affect the Company (each such circumstance, a “Suspension Event”); provided that (a) the Company shall not so delay filing or so suspend the use of the Registration Statement on more than three occasions during any calendar year or for more than 120 total days in any calendar year period, or on any occasion for a period of more than 60 consecutive days and (b) the Company shall use commercially reasonable efforts to make such Registration Statement available for the sale by such Purchaser and such Person of such securities as soon as practicable thereafter. Upon receipt of any such written notice from the Company of the occurrence of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, each Purchaser agrees that (i) it will immediately discontinue offers and sales of the Registrable Securities under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until such Purchaser receives copies of a supplemental or amended prospectus that corrects the misstatement(s) or omission(s) referred to above and such Purchaser receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law, subpoena, regulatory request, requirement or legal proceeding. If so directed by the Company, such Purchaser will deliver to the Company, or in such Purchaser’s sole discretion destroy, all copies of the prospectus covering the Registrable Securities in the Purchaser’s possession that contained such material misstatement or misleading information.

7.3    Required Information. The Company’s obligations to include the Registrable Securities (if any) for resale in the Registration Statement are contingent upon the Purchaser furnishing in writing to the Company such information required by SEC rules for the Registration Statement regarding such Purchaser, the securities of the Company held by the Purchaser, and the intended method of disposition of such securities, which shall be limited to non-underwritten public offerings, as shall be reasonably requested by the Company to effect the registration of the Registrable Securities, and shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations.

7.4    Indemnities.

a)    The Company shall, to the extent a Purchaser is a seller under the Registration Statement, indemnify and hold harmless each such Purchaser and the officers, directors, advisors and employees of such Purchaser, each Person who controls such Purchaser (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors and employees of each such controlling Person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable attorneys’ fees) and expenses (collectively, “Losses”) that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are caused by or contained in information regarding such Purchaser or such Person furnished in writing to the Company by such Purchaser or such Person expressly for use therein or that such Purchaser or such Person has omitted a material fact from such information. Notwithstanding the foregoing, the Company’s indemnification obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of the Company (which consent shall not be unreasonably withheld or delayed).

b)    Each Purchaser shall, severally and not jointly with any other Purchaser or any Person that purchased May 2022 Notes, indemnify and hold harmless the Company, its directors, officers, advisors and employees, each Person who controls the Company (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act), and the directors, officers and employees of such controlling Persons, to the fullest extent permitted by applicable law, from and against all Losses arising out of or based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements, alleged untrue statements, omissions or alleged omissions are caused by or contained in information regarding such Purchaser furnished in writing to the Company by such Purchaser expressly for use therein. In no event shall the liability of any Purchaser be greater in amount than the dollar amount of the net proceeds received by such Purchaser upon the sale of Registrable Securities giving rise to such indemnification obligation. Notwithstanding the foregoing, each Purchaser’s indemnification obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of such Purchaser (which consent shall not be unreasonably withheld or delayed).

3.  CONVERSION.

3.1    Optional Conversion. At any time during the period beginning on August 18, 2022 and ending on August 17, 2024, the entire Principal Balance and all accrued and unpaid interest then outstanding under this Note shall, at the option of the Holder, be convertible (in whole, not in part) into Conversion Shares at the Conversion Price. The Holder shall effect such conversion by providing the Company a conversion notice. Such conversion notice shall specify the entire Principal Balance and accrued but unpaid interest to be converted, the effective Conversion Price, and the effective date of conversion.

3.2    Mechanics of Conversion. Not later than five Business Days after any conversion date, the Company shall issue, or cause to be issued to the Holder the number of Conversion Shares being acquired upon the conversion of this Note. Upon conversion, this Note shall no longer be deemed to be outstanding and all rights with respect to this Notes shall immediately cease and terminate at the date of conversion, except only the right to receive Conversion Shares in exchange therefor as provided herein, and to receive payment in lieu of any fraction of a share otherwise issuable upon such conversion as provided herein. The Holder agrees to surrender this Note to the Company (or Lost Note Documentation where applicable) as soon as practicable after conversion, and the Holder shall not be entitled to receive any certificates representing the Conversion Shares issuable upon conversion of this Note unless and until Holder has surrendered the original of this Note (or Lost Note Documentation where applicable).

3.3    No Fractional Shares. No fractional shares shall be issued upon conversion of this Note. If upon any conversion of this Note, a fraction of a share would otherwise be issued, then in lieu of such fractional share, the Company shall at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Conversion Price or round up to the next whole share.

3.4    Reservation of Shares. The Company agrees that it will at all times reserve and keep available out of its authorized and unissued shares of Common Stock for the sole purpose of issuance upon conversion of this Note, free from preemptive rights or any other actual contingent purchase rights of persons other than the Holder, not less than such aggregate number of shares of the Common Stock as shall be issuable upon the conversion of this Note. The Company agrees that all Conversion Shares that shall be so issuable shall, upon issue in accordance with the terms herein, be duly authorized, validly issued, fully paid and nonassessable.

3.5    Adjustment to Conversion Price. If the Company at any time subdivides (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) its outstanding shares of Common Stock into a greater number of shares, the Conversion Price in effect immediately prior to such subdivision will be proportionately reduced, and if the Company at any time combines (by any stock split, stock dividend, stock combination, recapitalization or other similar transaction) its outstanding shares of Common Stock into a smaller number of shares, the Conversion Price in effect immediately prior to such combination will be proportionately increased. Any adjustment pursuant to this Section 3.5 shall become effective immediately after the effective date of such subdivision or combination. If any event requiring an adjustment under this Section 3.5 occurs during the period that a Conversion Price is calculated hereunder, then the calculation of such Conversion Price shall be adjusted appropriately to reflect such event.

3.6    Limitations on Conversion. Notwithstanding anything herein to the contrary, the Holder shall not attempt to convert any portion of this Note and the Company shall not issue to the Holder any Conversion Shares to the extent such shares, after giving effect to such issuance and when added to the number of shares of Conversion Shares issued and issuable to the other Holders pursuant to the other Notes and to the Persons that hold the May 2022 Notes, would result in the Holders and the Persons that hold the May 2022 Notes (and their respective affiliates) being issued Common Stock that in the aggregate would exceed (i) 19.99% of the number of shares of Common Stock outstanding (the “Maximum Aggregate Ownership Amount”), or (ii) 19.99% of the total voting power of the Company’s securities outstanding that are entitled to vote on a matter being voted on by holders of the Common Stock (the “Maximum Aggregate Voting Amount”), unless and until the Company obtains shareholder approval permitting such issuance in accordance with applicable rules of the NASDAQ Capital Market (or any other applicable national securities exchange) (“Stockholder Approval”). In determining the number of outstanding shares of Common Stock for purposes of this Section 3.6, the Holder may rely on the number of outstanding shares of Common Stock as reflected in (x) the Company’s most recent Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, filed with the Securities and Exchange Commission, (y) a more recent public announcement by the Company, or (z) any other notice by the Company or the Company's transfer agent setting forth the number of shares of Common Stock outstanding. If on any attempted conversion of this Note the resulting issuance of Conversion Shares would result in the Holders and the Persons that hold the May 2022 Notes (and their respective affiliates) exceeding the Maximum Aggregate Ownership Amount or the Maximum Aggregate Voting Amount and the Company shall not have previously obtained Stockholder Approval at the time of conversion, then the Company shall only issue to the Holder such number of Shares as may be issued below the Maximum Aggregate Ownership Amount or Maximum Aggregate Voting Amount, as the case may be.

4.    REDEMPTION.

4.1    Optional Redemption. At any time on or after August 18, 2025, the Company may, at its option and upon 30 days written notice provided to the Holder, elect to redeem the Note (in whole and not in part) and the Holder shall be obligated to surrender the Note, at a redemption price equal to 100% of the outstanding Principal Balance, together with any accrued but unpaid interest thereon to the redemption date. Notwithstanding the preceding or anything in Section 3 to the contrary, after receipt of such redemption notice from the Company, the Holder may, at its option, elect to convert the Principal Balance and accrued interest into Conversion Shares as set forth in Section 3 by giving written notice of such election to the Company no later than 5 days prior to the date fixed for redemption; provided that if the redemption notice is issued after May 31, 2027, the foregoing right of the Holder to elect to convert this Note into Conversion Shares shall not apply.

4.2    Change of Control Transactions. In the event the Company enters into a definitive agreement to consummate a Change of Control, the Company may, at its option and upon ten Business Days prior written notice to the Holder, elect to redeem the Note (in whole and not in part), and the Holder shall be obligated to surrender the Note, at a redemption price equal to 100% of the outstanding Principal Balance, together with any accrued but unpaid interest thereon to the redemption date. Notwithstanding the preceding or anything in Section 3 to the contrary, after receipt of such redemption notice from the Company, the Holder may, at its option, elect to convert the Principal Balance and accrued interest into Conversion Shares as set forth in Section 3 by giving written notice of such election to the Company no later than 15 days prior to the date fixed for redemption.

5.   EVENTS OF DEFAULT. Each of the following events shall constitute an “Event of Default” hereunder:

(e)    A receiver is appointed for any material part of the Company’s property, the Company makes a general assignment for the benefit of creditors, or the Company becomes a debtor or alleged debtor in a case under the U.S. Bankruptcy Code or becomes the subject of any other bankruptcy or similar proceeding for the general adjustment of its debts or for its liquidation; or

(f)    The Company’s Board of Directors adopts a resolution for the liquidation, dissolution or winding up of the Company.
