Certain capitalized terms used herein are defined in Section (12). The Issuance Date is the date of the first issuance of this Convertible Promissory Note (as amended, amended and restated, extended, supplemented or otherwise modified in

writing from time to time, this “Note”) regardless of the number of transfers and regardless of the number of instruments, which may be issued to evidence such Note.

This Note is being issued pursuant to Article II of the Prepaid Advance Agreement, dated as of March 27, 2024 (as may be amended, amended and restated, extended, supplemented or otherwise modified in writing from time to time, the “Agreement”), between the Company and the YA II PN, Ltd., as the Investor.

(1)GENERAL TERMS

(a)Maturity Date. On the Maturity Date, the Company shall pay to the Holder an amount in cash representing all outstanding Principal, accrued and unpaid Interest, and any other amounts outstanding pursuant to the terms of this Note. The "Maturity Date" shall be April 8, 2025, unless otherwise agreed by the parties. Other than as specifically permitted by this Note, the Company may not prepay or redeem any portion of the outstanding Principal and accrued and unpaid Interest.

(b)Interest Rate and Payment of Interest. Interest shall accrue on the outstanding Principal balance hereof at an annual rate equal to zero percent (0%) (“Interest Rate”), which Interest Rate shall increase to an annual rate of 18% upon the occurrence of an Event of Default (for so long as such event remains uncured or is not waived). Interest shall be calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law.

(c)Monthly Payments. If, any time after May 1, 2024, and from time to time thereafter, an Amortization Event has occurred, then the Company shall make monthly payments beginning on the third (3rd) Trading Day after the Amortization Event Date and continuing on the same day of each successive Calendar Month until the entire outstanding principal amount shall have been repaid. Each monthly payment shall be in an amount equal to the sum of (i) $9,000,000 of Principal in the aggregate among this Note and all Other Notes (or the outstanding Principal if less than such amount) (the “Amortization Principal Amount”), plus (ii) the Payment Premium (as defined below) in respect of such Amortization Principal Amount, and (iii) accrued and unpaid interest hereunder as of each payment date. The obligation of the Company to make monthly prepayments related to a Amortization Event shall cease (with respect to any payment that has not yet come due) if any time after the Amortization Event Date (A) in the event of a Floor Price Event, either (y) the daily VWAP is greater than 125% of the Floor Price then in effect for five (5) consecutive Trading Days, or (z) prior to the due date of a monthly payment, the Company has delivered a Reduction Notice and such reduced Floor Price shall not exceed 70% of the market price at the time of such Reduction Notice, or (B) in the event of an Exchange Cap Event, the Company obtains stockholder approval to increase the number of Common Shares under the Exchange Cap, or (C) in the event of a Registration Event, the condition or event causing the Registration Event is cured, unless a subsequent Amortization Event occurs. Any conversions of this Note into Common Shares made after the occurrence of an Amortization Event shall have the effect of reducing the amount of the next payment coming due as a result of such Amortization Event by an amount equal to the Principal amount of any such conversions.

(d)Optional Redemption. The Company at its option shall have the right, but not the obligation, to redeem (“Optional Redemption”) early a portion or all amounts outstanding under this Note as described in this Section; provided that the Company provides the Holder with written notice (each, a “Redemption Notice”) of its desire to exercise an Optional Redemption, which Redemption Notice (i) shall be delivered to the Holder after the close of regular trading hours on a Trading Day, and (ii) may only be given (x) if the VWAP of the Common Shares was less than the Fixed Price on the date such Redemption Notice is delivered, unless otherwise agreed by the Holder, or (y) at any time after the tenth (10th) Trading Day after the initial Registration Statement has been declared effective. Each Redemption Notice shall be irrevocable and shall specify the outstanding balance of the Note to be redeemed and the Redemption Amount. The “Redemption Amount” shall be an amount equal to the outstanding Principal balance being redeemed by the Company, plus the Payment Premium in respect of such Principal amount, plus all accrued and unpaid interest, if any on such Principal amount. After receipt of a Redemption Notice, the Holder shall have ten (10) Trading Days (beginning with the Trading Day immediately following the date of such Redemption Notice) to elect to convert all or any portion of the Note. On the eleventh (11th) Trading Day after the applicable Redemption Notice, the Company shall deliver to the Holder the Redemption Amount with respect to the Principal amount redeemed to the extent not converted and otherwise after giving effect to conversions or other payments made during the ten (10) Trading Day period.

(e)Payment Dates. Whenever any payment or other obligation hereunder shall be due on a day other than a Business Day, such payment shall be made on the next succeeding Business Day. If the Holder is the holder of this Note and Other Notes, then any payments made to the Holder shall be allocated to each note as determined in the sole discretion of the Holder.

(3)CONVERSION OF NOTE.    This Note shall be convertible into shares of the Company's Common Shares, on the terms and conditions set forth in this Section (3).

(a)Conversion Right. Subject to the limitations of Section (3)(c), at any time or times on or after the Issuance Date, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and nonassessable Common Shares in accordance with Section (3)(b), at the Conversion Price. The number of Common Shares issuable upon conversion of any Conversion Amount pursuant to this Section (3)(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price. The Company shall not issue any fraction of a share of Common Shares upon any conversion. All calculations under this Section (3) shall be rounded to the nearest $0.0001. If the issuance would result in the issuance of a fraction of a share of Common Shares, the Company shall round such fraction of a share of Common Shares up to the nearest whole share. The Company shall pay any and all transfer, stamp and similar taxes that may be payable with respect to the issuance and delivery of Common Shares upon conversion of any Conversion Amount.

(b)Mechanics of Conversion.

(i)Optional Conversion. To convert any Conversion Amount into Common Shares on any date (a "Conversion Date"), the Holder shall (A) transmit by email

(or otherwise deliver), for receipt on or prior to 11:59 p.m., New York Time, on such date, a copy of an executed notice of conversion in the form attached hereto as Exhibit I (the "Conversion Notice") to the Company and (B) if required by Section (3)(b)(iii), surrender this Note to a nationally recognized overnight delivery service for delivery to the Company (or an indemnification undertaking reasonably satisfactory to the Company with respect to this Note in the case of its loss, theft or destruction). On or before the third (3rd) Trading Day following the date of receipt of a Conversion Notice (the "Share Delivery Date"), the Company shall (X) if legends are not required to be placed on certificates of Common Shares and provided that the Transfer Agent is participating in the Depository Trust Company's ("DTC") Fast Automated Securities Transfer Program, credit such aggregate number of Common Shares to which the Holder shall be entitled to the Holder's or its designee's balance account with DTC through its Deposit Withdrawal Agent Commission system or (Y) if the Transfer Agent is not participating in the DTC Fast Automated Securities Transfer Program, issue and deliver to the address as specified in the Conversion Notice, a certificate, registered in the name of the Holder or its designee, for the number of Common Shares to which the Holder shall be entitled which certificates shall not bear any restrictive legends unless required pursuant to rules and regulations of the Commission. If this Note is physically surrendered for conversion and the outstanding Principal of this Note is greater than the Principal portion of the Conversion Amount being converted, then the Company shall as soon as practicable and in no event later than three (3) Business Days after receipt of this Note and at its own expense, issue and deliver to the holder a new Note representing the outstanding Principal not converted. The Person or Persons entitled to receive the Common Shares issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such Common Shares upon the transmission of a Conversion Notice.

(ii)Company's Failure to Timely Convert. If within three (3) Trading Days after the Company's receipt of an email copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Holder or credit the Holder's balance account with DTC for the number of Common Shares to which the Holder is entitled upon such holder's conversion of any Conversion Amount (a "Conversion Failure"), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Shares to deliver in satisfaction of a sale by the Holder of Common Shares issuable upon such conversion that the Holder anticipated receiving from the Company (a "Buy-In"), then the Company shall, within three (3) Business Days after the Holder's request and in the Holder's discretion, either (i) pay cash to the Holder in an amount equal to the Holder's total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the Common Shares so purchased (the “Buy-In Price”), at which point the Company's obligation to deliver such certificate (and to issue such Common Shares) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates representing such Common Shares and pay cash to the Holder in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of Common Shares, times (B) the Closing Price on the Conversion Date.

(iii)Book-Entry. Notwithstanding anything to the contrary set forth herein, upon conversion of any portion of this Note in accordance with the terms hereof, the

Holder shall not be required to physically surrender this Note to the Company unless (A) the full Conversion Amount represented by this Note is being converted or (B) the Holder has provided the Company with prior written notice (which notice may be included in a Conversion Notice) requesting reissuance of this Note upon physical surrender of this Note. The Holder and the Company shall maintain records showing the Principal and Interest converted and the dates of such conversions or shall use such other method, reasonably satisfactory to the Holder and the Company, so as not to require physical surrender of this Note upon conversion.

(i)Beneficial Ownership. The Holder shall not have the right to convert any portion of this Note to the extent that after giving effect to such conversion, the Holder, together with any affiliate thereof, would beneficially own (as determined in accordance with Section 13(d) of the Exchange Act and the rules promulgated thereunder) in excess of 4.99% of the number of Common Shares outstanding immediately after giving effect to such conversion or receipt of shares as payment of interest. Since the Holder will not be obligated to report to the Company the number of Common Shares it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of Common Shares in excess of 4.99% of the then outstanding Common Shares without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority and obligation to determine whether the restriction contained in this Section will limit any particular conversion hereunder and to the extent that the Holder determines that the limitation contained in this Section applies, the determination of which portion of the Principal amount of this Note is convertible shall be the responsibility and obligation of the Holder. If the Holder has delivered a Conversion Notice for a Principal amount of this Note that, without regard to any other shares that the Holder or its affiliates may beneficially own, would result in the issuance in excess of the permitted amount hereunder, the Company shall notify the Holder of this fact and shall honor the conversion for the maximum Principal amount permitted to be converted on such Conversion Date in accordance with Section (3)(a) and, any Principal amount tendered for conversion in excess of the permitted amount hereunder shall remain outstanding under this Note. The provisions of this Section may be waived by a Holder (but only as to itself and not to any other Holder) upon not less than 65 days prior notice to the Company. Other Holders shall be unaffected by any such waiver. The Holder acknowledges that the Holder is solely responsible for any calculations hereunder and that the Company is not representing to the Holder that any such calculation hereunder is in compliance with Section 13(d) of the Exchange Act.

(ii)Principal Market Limitation. Notwithstanding anything in this Note to the contrary, the Company shall not issue any Common Shares upon conversion of this Note, or otherwise, if the issuance of such Common Shares, together with any Common Shares issued in connection the Agreement and with any other related transactions that may be considered part of the same series of transactions, would exceed the aggregate number Common Shares that the Company may issue in a transaction in compliance with the Company’s obligations under the rules or regulations of Nasdaq Stock Market LLC (the “Nasdaq”) and shall be referred to as the “Exchange Cap,” except that such limitation shall not apply if the

Company’s stockholders have approved such issuances on such terms in excess of the Exchange Cap in accordance with the rules of the Nasdaq.

(iii)Other Conversion Limitations. Except as set forth below, the Holder shall not (a) submit any Conversion Notice prior to May 1, 2024, or (b) submit Conversion Notices in respect of more than $9,000,000 of the outstanding Principal balance under this Note and the Other Notes, plus accrued and unpaid interest, if any, in the aggregate in any monthly period beginning on the first day of such month and ending on the last day of the same month. This Section (3)(c)(iii) shall not apply (i) at any time upon the occurrence and during the continuance of an Event of Default, and (ii) with respect to any Conversion Notice where the Conversion Price is equal to the Fixed Price. This Section (3)(c)(iii) may be waived with the written consent of the Company.

(i)All calculations under this Section (4) shall be rounded to the nearest $0.0001 or whole share.

(ii)Legal Opinions. The Company is obligated to cause its legal counsel to deliver legal opinions to the Company’s transfer agent in connection with any legend removal upon the expiration of any holding period or other requirement for which the Underlying Shares may bear legends restricting the transfer thereof. To the extent that a legal opinion is not provided (either timely or at all), then, in addition to being an Event of Default hereunder, the Company agrees to reimburse the Holder for all reasonable costs incurred by the Holder in connection with any legal opinions paid for by the Holder in connection with sale or transfer of Underlying Common Shares. The Holder shall notify the Company of any such costs and expenses it incurs that are referred to in this section from time to time and all amounts owed hereunder shall be paid by the Company with reasonable promptness.

(e)Adjustment of Conversion Price upon Subdivision or Combination of Common Shares. If the Company, at any time while this Note is outstanding, shall (a) pay a stock dividend or otherwise make a distribution or distributions on shares of its Common Shares or any other equity or equity equivalent securities payable in Common Shares, (b) subdivide outstanding Common Shares into a larger number of shares, (c) combine (including by way of reverse stock split) outstanding Common Shares into a smaller number of shares, or (d) issue by reclassification of Common Shares any shares of capital stock of the Company, then each of the Fixed Price and the Floor Price shall be multiplied by a fraction of which the numerator shall be the number of Common Shares (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of Common Shares outstanding after such event. Any adjustment made pursuant to this Section shall become effective immediately after the record date for the determination of stockholders entitled to receive such dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or re-classification.

(f)Other Corporate Events. In addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant

to which holders of Common Shares are entitled to receive securities or other assets with respect to or in exchange for Common Shares (a "Corporate Event"), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Note, at the Holder's option, (i) in addition to the Common Shares receivable upon such conversion, such securities or other assets to which the Holder would have been entitled with respect to such Common Shares had such Common Shares been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of this Note) or (ii) in lieu of the Common Shares otherwise receivable upon such conversion, such securities or other assets received by the holders of Common Shares in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had this Note initially been issued with conversion rights for the form of such consideration (as opposed to Common Shares) at a conversion rate for such consideration commensurate with the Conversion Price. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders. The provisions of this Section shall apply similarly and equally to successive Corporate Events and shall be applied without regard to any limitations on the conversion or redemption of this Note.

(g)Whenever the Conversion Price is adjusted pursuant to Section (3) hereof, the Company shall promptly provide the Holder with a written notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

(h)In case of any (1) merger or consolidation of the Company or any Subsidiary of the Company with or into another Person, or (2) sale by the Company or any Subsidiary of the Company of more than one-half of the assets of the Company in one or a series of related transactions, a Holder shall have the right to (A) exercise any rights under Section (3)(b), (B) convert the aggregate amount of this Note then outstanding into the shares of stock and other securities, cash and property receivable upon or deemed to be held by holders of Common Shares following such merger, consolidation or sale, and such Holder shall be entitled upon such event or series of related events to receive such amount of securities, cash and property as the Common Shares into which such aggregate Principal amount of this Note could have been converted immediately prior to such merger, consolidation or sales would have been entitled, or (C) in the case of a merger or consolidation, require the surviving entity to issue to the Holder a convertible Note with a Principal amount equal to the aggregate Principal amount of this Note then held by such Holder, plus all accrued and unpaid interest and other amounts owing thereon, which such newly issued convertible Note shall have terms identical (including with respect to conversion) to the terms of this Note, and shall be entitled to all of the rights and privileges of the Holder of this Note set forth herein and the agreements pursuant to which this Note was issued. In the case of clause (C), the conversion price applicable for the newly issued shares of convertible preferred stock or convertible debentures shall be based upon the amount of securities, cash and property that each Common Shares would receive in such transaction and the Conversion Price in effect immediately prior to the effectiveness or closing date for such transaction. The terms of any such merger, sale or consolidation shall include such terms so as to continue to give the Holder the right to receive the securities, cash and property set forth in this

Section upon any conversion or redemption following such event. This provision shall similarly apply to successive such events.

(4)REISSUANCE OF THIS NOTE.

(a)Transfer. If this Note is to be transferred, the Holder shall surrender this Note to the Company, whereupon the Company will forthwith issue and deliver upon the order of the Holder a new Note (in accordance with Section (4)(d)), registered in the name of the registered transferee or assignee, representing the outstanding Principal being transferred by the Holder (along with any accrued and unpaid interest thereof) and, if less than the entire outstanding Principal is being transferred, a new Note (in accordance with Section (4)(d)) to the Holder representing the outstanding Principal not being transferred.
