**Item 1.01 Entry into a Material Definitive Agreement.**

On March 17, 2023, Eos Energy Enterprises, Inc. (the "Company") and YA II PN, LTD ("Yorkville") entered into Amendment No 4. ("Amendment No. 4") to the Standby Equity Purchase Agreement dated as of April 28, 2022 (as amended, the "SEPA"), to clarify that the Exchange Cap (as defined in the SEPA) does not apply (a) if the Company's stockholders have approved issuances in excess of the Exchange Cap, or (b) to sales of shares of common stock under the SEPA at a price that equals or exceeds $1.88 per share (which represents the lower of (x) the Nasdaq Official Closing Price on the Trading Day (each as defined in the SEPA) immediately preceding March 17, 2023, the date of issuance of the Promissory Note (as defined below); and (y) the average Nasdaq Official Closing Price for the five Trading Days immediately preceding March 17, 2023; provided that, in the case of clause (b), the average price of all applicable sales of shares of common stock under the SEPA after December 29, 2022 equals or exceeds $1.88 per share.

With the exception of the foregoing description of Amendment No. 4, the terms of the SEPA remain unchanged, and the SEPA, as amended, remains in full force and effect.

The foregoing description of Amendment No. 4 does not purport to be complete and is qualified in its entirety by reference to the full text of Amendment No. 4, a copy of which is filed with this Current Report on Form 8-K as Exhibit 10.1 hereto and is hereby incorporated by reference.

*Supplemental Agreement to the SEPA and Promissory Note Issuance*

On March 17, 2023, the Company issued and sold a convertible promissory note with an aggregate principal amount of $15.0 million (the "Promissory Note") in a private placement to Yorkville under a supplemental agreement dated as of March 17, 2023 (the "Third Supplemental Agreement") to the SEPA between the Company and Yorkville.

The Company agreed to use the proceeds from the sale of the Promissory Note for working capital and other general corporate purposes or, if different, in a manner consistent with the application thereof described in the Company's prospectus relating to the SEPA filed with the Securities and Exchange Commission on April 28, 2022 and included as a part of the Company's Registration Statement on Form S-3 (File No. 333-263298).

The Promissory Note has a maturity date of August 17, 2023 (the "Maturity Date") and was issued with a 2% original issue discount. Interest shall accrue on the outstanding principal balance of the Promissory Note, beginning on the 29th day following the date of issuance, at an annual rate equal to 5.0% unless and until there is an event of default, upon the occurrence of which, interest shall accrue at a rate of 15% per year until collected in full. The Promissory Note is convertible into shares of the Company's common stock at a conversion price equal to the lower of $1.9368 and 92.5% of the lowest daily volume weighted average price of the Company's common stock during the seven (7) consecutive trading days immediately preceding the conversion date (the "Conversion Price") any time prior to the Maturity Date, subject to the terms and conditions of the Promissory Note. The Conversion Price may not be less than $0.35 per share (the "Floor Price"). If the volume weighted average price of the Company's common stock is less than the Floor Price for five consecutive trading days, subject to certain limitations, the Company must make weekly payments on the Promissory Note. At any time that there is an outstanding balance owed under the Promissory Note, Yorkville may, pursuant to the terms of the Third Supplemental Agreement, require the Company to deliver an advance under the SEPA for the issuance and sale of common stock at the Conversion Price in order to offset the amounts owed by the Company to Yorkville under the Promissory Note. In addition, while there is an outstanding balance owed under the Promissory Note, Yorkville shall use any advance requested by the Company pursuant to the SEPA to offset the amounts owed by the Company to Yorkville under the Promissory Note.

The foregoing descriptions of the Third Supplemental Agreement and the Promissory Note do not purport to be complete and are qualified in their entirety by reference to the full text of each of the Third Supplemental Agreement and the Promissory Note, copies of which are filed with this Current Report on Form 8-K as Exhibit 10.2 and Exhibit 4.1 hereto, respectively, and are hereby incorporated herein by reference.

**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The information set forth in Item 1.01 of this Current Report on Form 8-K under the heading "Supplemental Agreement to the SEPA and Promissory Note Issuance" is incorporated herein by reference.

**Item 3.02 Unregistered Sales of Equity Securities.**

The information set forth under Item 1.01 of this Current Report on Form 8-K under the heading "Supplemental Agreement to the SEPA and Promissory Note Issuance" is incorporated herein by reference.

On March 17, 2023, the Company issued and sold the Promissory Note to Yorkville in a private placement pursuant to the exemption from the registration requirements of the Securities Act of 1933, as amended (the "Securities Act"). The Company offered and sold the Promissory Note to Yorkville in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act without the involvement of any underwriter. The Company relied on this exemption from registration based in part on representations made by Yorkville in the Third Supplemental Agreement and the SEPA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) <u>GENERAL TERMS</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Maturity Date</u>.

Beginning on the 29<sup>th</sup> day following the Issuance Date, Interest shall accrue on the outstanding Principal balance hereof at an annual rate equal to 5% ("<u>Interest Rate</u>"), which Interest Rate shall increase to an annual rate of 15% upon an Event of Default for so long as it remains uncured. Interest shall be calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Mandatory Payments</u>. Subject to the provisions of Section 3(c)(ii), if, any time after the Issuance Date, and from time to time thereafter, a Trigger Event occurs, then the Company shall make weekly payments (in accordance with Section 1(d)) beginning on the later of (i) the 10<sup>th</sup> calendar day after the Trigger Date, and (ii) in the event the Trigger Date occurs during or within two Trading Days preceding a Company Black Out Period (as defined in Section 15), the 5<sup>th</sup> calendar day after the cessation of such Company Black Out Period, and continuing on the same day of each successive calendar week. Each weekly payment shall be in an amount equal to the sum of (i) $1,000,000 of Principal (or the outstanding Principal if less than such amount) (the "<u>Triggered Principal Amount</u>"), (ii) solely with respect to a Trigger Event caused by a Floor Price Trigger, the Payment Premium (as defined below, and if applicable in accordance with Section 1(d)) in respect of such Triggered Principal Amount, and (iii) accrued and unpaid interest hereunder as of each payment date (collectively, the "<u>Payment Amount</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Weekly Payments</u>.

Upon the closing of such Advance Notice in accordance with Section 2.02 of the SEPA, the Holder shall offset the amount due to be paid by the Holder to the Company under the SEPA against the portion of the Payment Amount to be paid by the Advance Repayment. If any portion of the Payment Amount remains unpaid at the applicable due date, the Company shall repay such outstanding Payment Amount pursuant to (ii) or (iii) of this Section 1(d), provided that, in each case, any such repayment would not violate the terms of the Atlas Facility.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>Optional Redemption</u>. The Company at its option shall have the right, but not the obligation, to redeem ("<u>Optional Redemption</u>") early a portion or all amounts outstanding under this Note as described in this Section; *provided* that (i) the Company provides the Holder with at least five Trading Days' prior written notice (each, a "<u>Redemption Notice</u>") of its desire to exercise an Optional Redemption, and (ii) the VWAP of the Company's Common Stock on each of the ten Trading Days immediately prior to the Redemption Notice is less than the Fixed Conversion Price, Each Redemption Notice shall be irrevocable and shall specify the outstanding balance of the Note to be redeemed. The "<u>Redemption Amount</u>" shall be equal to the outstanding Principal balance being redeemed by the Company, plus the Payment Premium, plus all accrued and unpaid interest. After receipt of the Redemption Notice, the Holder shall have five Trading Days to elect to convert all or any portion of this Note. On the sixth Trading Day after the Redemption Notice, the Company shall deliver to the Holder the Redemption Amount with respect to the Principal amount redeemed after giving effect to conversions effected during the five Trading Day period. The Holder may convert all or any part of this Note after receiving a Redemption Notice, in which case the Redemption Amount shall be reduced by the amount so converted.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi) The Company shall fail to observe or perform any other material covenant, agreement or warranty contained in, or otherwise commit any material breach or default of any provision of this Note (except as may be covered by Section 2(a)(i) through 2(a)(xi) hereof) or any Transaction Document (as defined in Section 15) which is not cured within any cure period prescribed therein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) During the time that any portion of this Note is outstanding, if any Event of Default has occurred and is *continuing*, (other than an event with respect to the Company described in Section 2(a)(ii)), the full unpaid Principal amount of this Note and the Payment Premium, together with interest and other amounts owing in respect thereof, to the date of acceleration shall become at the Holder's election, immediately due and payable in cash; <u>provided</u> that, in case of any event with respect to the Company described in Section 2(a)(ii), the full Principal amount of this Note and the Payment Premium, together with interest and other amounts owing in respect thereof to the date of acceleration, shall automatically become due and payable. Furthermore, in addition to any other remedies, the Holder shall have the right (but not the obligation) to convert this Note (subject to the limitations set out in Section 3(c)) at any time after (x) an Event of Default or (y) the Maturity Date at the Conversion Price. The Holder need not provide and the Company hereby waives any presentment, demand, protest or other notice of any kind, (other than required notice of conversion) and the Holder may immediately enforce any and all of its rights and remedies hereunder and all other remedies available to it under applicable law. Such declaration may be rescinded and annulled by Holder at any time prior to payment hereunder. No such rescission or annulment shall affect any subsequent Event of Default or impair any right consequent thereon. For the purposes hereof, an Event of Default relating to default in payment is "*continuing*" if it has not been waived, and an Event of Default relating to circumstances other than a default in payment is "*continuing*" if it has not been remedied or waived.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) <u>CONVERSION OF NOTE</u>. This Note shall be convertible into shares of the Company's Common Stock, on the terms and conditions set forth in this Section 3.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Conversion Right</u>. Subject to the provisions of this Section 3 and subject to the limitations on conversion set forth in Section 3(c)(ii), 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 (as defined below) into fully paid and nonassessable shares of Common Stock, at the Conversion Price. The number of shares of Common Stock 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 Stock upon any conversion. If the issuance would result in the issuance of a fraction of a share of Common Stock, the Company shall round such fraction of a share of Common Stock up or down 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 Stock upon conversion of any Conversion Amount.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) "<u>Conversion Amount</u>" means the portion of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) "<u>Conversion Price</u>" means, as of any Conversion Date (as defined below) or other date of determination the lower of (i) $1.9368 per share (the "<u>Fixed Conversion Price</u>"), or (ii) 92.5% of the lowest daily VWAP of the Common Stock during the seven (7) consecutive Trading Days immediately preceding the Conversion Date or other date of determination (the "<u>Variable Conversion Price</u>") but not lower than the Floor Price. The Conversion Price shall be adjusted from time to time pursuant to the other terms and conditions of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Mechanics of Conversion</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Optional Conversion</u>. To convert any Conversion Amount into shares of Common Stock on any date (a "<u>Conversion Date</u>"), the Holder shall (A) transmit by email with confirmation of delivery (or otherwise deliver by method set forth in Section 5), 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 <u>Exhibit I</u> (the "<u>Conversion Notice</u>") to the Company and (B) if required by Section 3(c)(ii), 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 (3<sup>rd</sup>) Business Day following the date of receipt of a Conversion Notice (the "<u>Share Delivery Date</u>"), the Company shall issue and deliver to the address as specified in the Conversion Notice, a certificate (or book entry), registered in the name of the Holder or its designee, for the number of shares of Common Stock to which the Holder shall be entitled. Any shares of Common Stock issued upon conversion shall bear customary restrictive legends regarding restrictions on transfers under the applicable securities laws. If this Note is physically surrendered for conversion and the outstanding balance of this Note is greater than the 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 balance not converted. The Person or Persons entitled to receive the shares of Common Stock issuable upon a conversion of this Note shall be treated for all purposes as the record holder or holders of such shares of Common Stock upon the receipt of a Conversion Notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>Company's Failure to Timely Convert</u>. If within three (3) from the Share Delivery Date the Company shall fail to issue and deliver a certificate to the Holder, issue a book entry in the name of the Holder or credit the Holder's balance account with DTC for the number of shares of Common Stock to which the Holder is entitled upon such holder's conversion of any Conversion Amount (a "<u>Conversion Failure</u>"), and if on or after such Trading Day the Holder purchases (in an open market transaction or otherwise) Common Stock to deliver in satisfaction of a sale by the Holder of Common Stock issuable upon such conversion that the Holder anticipated receiving from the Company and that is saleable under Rule 144 at the time of such conversion (a "<u>Buy-In</u>"), 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 shares of Common Stock so purchased (the "<u>Buy-In Price</u>"), at which point the Company's obligation to deliver such certificate or book entry (and to issue such Common Stock) shall terminate, or (ii) promptly honor its obligation to deliver to the Holder a certificate or certificates or book entries representing such Common Stock 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 shares of Common Stock, times (B) the Closing Bid Price on the Conversion Date and such approval is applicable to issuances of shares of Common Stock upon conversion of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) <u>Book-Entry</u>. 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 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Limitations on Conversions</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) <u>Beneficial Ownership</u>. 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 9.99% of the number of shares of Common Stock outstanding immediately after giving effect to such conversion. Since the Holder will not be obligated to report to the Company the number of shares of Common Stock it may hold at the time of a conversion hereunder, unless the conversion at issue would result in the issuance of shares of Common Stock in excess of 9.99% of the then outstanding shares of Common Stock without regard to any other shares which may be beneficially owned by the Holder or an affiliate thereof, the Holder shall have the authority, responsibility 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. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) <u>Principal Market Limitations</u>. Notwithstanding anything in this Note to the contrary, the Holder shall not have the right to convert any portion of this Note, and the Company shall not issue any shares of Common Stock upon conversion of this Note, or otherwise, if the conversion and issuance of such Common Stock, together with any Common Stock issued in connection the SEPA and with any other related transactions that may be considered part of the same series of transactions, would exceed the aggregate number of shares of Common Stock 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 "<u>Nasdaq</u>") and shall be referred to as the "<u>Exchange Cap,</u>" 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. Any failure by the Company to issue shares as a result of the limitations imposed by this Section 3(c)(ii) shall in nowise be considered (i) a breach or default of any provision of this Note or (ii) an Event of Default under Section 2(a)(vi), and such failure shall not trigger any of the Holder's rights or remedies under Section 2(b), and shall not result in the payment of any penalty to the Holder by the Company, including, but not limited to the Payment Premium.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Other Provisions</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Company shall at all times reserve and keep available out of its authorized Common Stock the full number of shares of Common Stock issuable upon conversion of all outstanding amounts under this Note, and within three (3) Business Days following the receipt by the Company of a Holder's notice that such minimum number of Underlying Shares is not so reserved, the Company shall promptly reserve a sufficient number of shares of Common Stock to comply with such requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) All calculations under this Section 3 shall be rounded to the nearest $0.0001 or whole share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Nothing herein shall limit a Holder's right to pursue actual damages or declare an Event of Default pursuant to Section 2 herein for the Company's failure to deliver certificates or issue book entries representing shares of Common Stock upon conversion within the period specified herein and such Holder shall have the right to pursue all remedies available to it at law or in equity including, without limitation, a decree of specific performance and/or injunctive relief, in each case without the need to post a bond or provide other security. The exercise of any such rights shall not prohibit the Holder from seeking to enforce damages pursuant to any other Section hereof or under applicable law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) <u>Conversion Costs</u>. 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 of Underlying Shares (provided that the Company has first had the opportunity to obtain such a legal opinion on behalf of the Holder). 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) <u>Adjustments to Conversion Price upon Subdivision or Combination of Common Stock</u>. 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 its Common Stock or any other equity or equity equivalent securities payable in shares which results in an increase in the number of outstanding Common Stock, (b) subdivide its outstanding Common Stock into a larger number, or (c) combine (including by way of reverse share split) outstanding Common Stock into a smaller number, then the Conversion Price shall be multiplied by a fraction of which the numerator shall be the number of shares of Common Stock (excluding treasury shares, if any) outstanding before such event and of which the denominator shall be the number of shares of Common Stock 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 or combination.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Whenever the Conversion Price is adjusted pursuant to Section 3 hereof, the Company shall promptly mail to the Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) In case of any (1) merger or consolidation of the Company or any subsidiary of the Company controlling more than one-half of the assets of the Company with or into another Person not affiliated with the Company, 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, the Holder shall have the right to (A) exercise any rights under Section (3), (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 shares of Common Stock 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 shares of Common Stock 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 Notes were issued. In the case of clause (C), the conversion price applicable for the newly issued Convertible Notes shall be based upon the amount of securities, cash and property that each share of Common stock 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) <u>REISSUANCE OF THIS NOTE</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) <u>Transfer</u>. 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 then 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. The Holder and any assignee, by acceptance of this Note benture, acknowledge and agree that, by reason of the provisions of Section 3(c)(ii) following conversion, repayment, or redemption of any portion of this Note, the outstanding Principal represented by this Note may be less than the Principal stated on the face of this Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Lost, Stolen or Mutilated Note</u>. Upon receipt by the Company of evidence reasonably satisfactory to the Company of the loss, theft, destruction or mutilation of this Note, and, in the case of loss, theft or destruction, of any indemnification undertaking by the Holder to the Company in customary form and, in the case of mutilation, upon surrender and cancellation of this Note, the Company shall execute and deliver to the Holder a new Note (in accordance with Section 4(d)) representing the outstanding Principal.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) <u>Note Exchangeable for Different Denominations</u>. This Note is exchangeable, upon the surrender hereof by the Holder at the principal office of the Company, for a new Note or Notes (in accordance with Section 4(d)) representing in the aggregate the outstanding Principal of this Note, and each such new Note will represent such portion of such outstanding Principal as is designated by the Holder at the time of such surrender.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Issuance of New Notes</u>. Whenever the Company is required to issue a new Note pursuant to the terms of this Note, such new Note (i) shall be of like tenor with this Note, (ii) shall represent, as indicated on the face of such new Note, the Principal remaining outstanding (or in the case of a new Note being issued pursuant to Section 4(a) or Section 4(c), the Principal designated by the Holder which, when added to the principal represented by the other new Notes issued in connection with such issuance, does not exceed the Principal remaining outstanding under this Note immediately prior to such issuance of new Noted), (iii) shall have an issuance date, as indicated on the face of such new Note, which is the same as the Issuance Date of this Note, (iv) shall have the same rights and conditions as this Note, and (v) shall represent accrued and unpaid Interest from the Issuance Date.

Any notices, consents, waivers or other communications required or permitted to be given under the terms hereof must be in writing and will be deemed to have been delivered: upon the later of (A) either (i) receipt, when delivered personally or (ii) one (1) Business Day after deposit with an overnight courier service with next day delivery specified, in each case, properly addressed to the party to receive the same and (B) receipt, when sent by e-mail.

Written confirmation of receipt (i) given by the recipient of such notice, consent, waiver or other communication, (ii) electronically generated upon sending the e-mail or (iii) provided by a nationally recognized overnight delivery service, shall be rebuttable evidence of personal service, receipt by e-mail or receipt from a nationally recognized overnight delivery service in accordance with clause (i), (ii) or (iii) above, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(6) Except as expressly provided herein, no provision of this Note shall alter or impair the obligations of the Company, which are absolute and unconditional, to pay the principal of, interest and other charges (if any) on, this Note at the time, place, and rate, and in the coin or currency, herein prescribed. This Note is a direct obligation of the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) This Note shall not entitle the Holder to any of the rights of a stockholder of the Company, including without limitation, the right to vote, to receive dividends and other distributions, or to receive any notice of, or to attend, meetings of stockholders or any other proceedings of the Company, unless and to the extent converted into shares of Common Stock in accordance with the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(8) This Note shall be governed by and construed in accordance with the laws of the State of New York, without giving effect to conflicts of laws thereof. Each of the parties consents to the jurisdiction of the Courts of the State of New York sitting in New York County, New York and the U.S. District Court for the Southern District of New York sitting in New York County, New York in connection with any dispute arising under this Note and hereby waives, to the maximum extent permitted by law, any objection, including any objection based on forum non conveniens to the bringing of any such proceeding in such jurisdictions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(9) If the Company fails to strictly comply with the terms of this Note, then the Company shall reimburse the Holder promptly for all fees, costs and expenses, including, without limitation, attorneys' fees and expenses incurred by the Holder in any action in connection with this Note, including, without limitation, those incurred: (i) during any workout, attempted workout, and/or in connection with the rendering of legal advice as to the Holder's rights, remedies and obligations, (ii) collecting any sums which become due to the Holder, (iii) defending or prosecuting any proceeding or any counterclaim to any proceeding or appeal; or (iv) the protection, preservation or enforcement of any rights or remedies of the Holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) Any waiver by the Holder of a breach of any provision of this Note shall not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Note. The failure of the Holder to insist upon strict adherence to any term of this Note on one or more occasions shall not be considered a waiver or deprive that party of the right thereafter to insist upon strict adherence to that term or any other term of this Note. Any waiver must be in writing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Investor shall, in each Investor Notice, select the amount of the Advance, in its sole discretion, and the timing of delivery; provided that the amount of the Advance shall not exceed (i) the outstanding balance owed under the Promissory Note on the date of delivery of the Investor Notice, or (ii) the amount that would cause the aggregate number of Common Shares beneficially owned (as calculated pursuant to Section 13(d) of the Exchange Act) by the Investor and its Affiliates as a result of previous issuances and sales of Common Shares to Investor under this Agreement and the SEPA to exceed 9.99% of the then outstanding Common Shares (the "<u>Ownership Limitation</u>"). In connection with each Investor Notice delivered by the Investor, any portion of the Advance that would (i) cause the Investor to exceed the Ownership Limitation or (ii) cause the aggregate number of Shares issued and sold to the Investor hereunder to exceed the Commitment Amount shall automatically be withdrawn with no further action required by the Company, and such Investor Notice shall be deemed automatically modified to reduce the amount of the Advance requested by an amount equal to such withdrawn portion; provided that in the event of any such automatic withdrawal and automatic modification, the Investor will promptly notify the Company of such event.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) The Purchase Price of the Shares in respect of any Advance Notice delivered pursuant to an Investor Notice shall be equal to the Conversion Price (as defined in the Promissory Note) in effect on the date of delivery of the Investor Notice.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Investor Notices shall be delivered in accordance with the instructions set forth at the bottom of <u>Exhibit B</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Upon the deemed delivery of an Investor Notice in accordance with Section 3.1(c) above, a corresponding Advance Notice shall simultaneously be deemed to have been delivered by the Company to the Investor, and any conditions precedent to such Advance Notice under the terms of the SEPA that have not been satisfied shall be deemed to have been waived by the Investor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Notwithstanding anything to the contrary in this Agreement, if on any day that an Investor Notice is delivered (i) the Company notifies the Investor that a Material Outside Event has occurred, or (ii) the Company notifies the Investor of a Black Out Period, the parties agree that such Investor Notice shall be automatically withdrawn.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.2 <u>Closings of an Advance Notice delivered pursuant to an Investor Notice</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) In respect of an Advance Notice deemed to be delivered pursuant to Section 3.1 above, the Advance Date shall be the date that the Advance Notice is deemed to be delivered.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In respect of an Advance Notice deemed to be delivered pursuant to Section 3.1 above, the Investor shall pay the aggregate purchase price of the Shares (as set forth in the Settlement Document) by offsetting the amount of the aggregate purchase price of the Shares to be paid by the Investor against an equal amount outstanding under the Promissory Note (first towards accrued and unpaid interest, and then towards outstanding principal, with no deduction for any Payment Premium, as defined in the Promissory Note).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The closing of each Advance Notice deemed to be delivered pursuant to Section 3.1 above and issuance of Shares related to such Advance Notice (each, an "<u>Advance Notice Closing</u>") shall take place as soon as practicable on or after each Advance Date in accordance with the procedures set forth below. In connection with each Advance Notice Closing, the Company and the Investor shall fulfill each of its obligations as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) On each Advance Date, the Investor shall deliver to the Company a written document, in the form attached hereto as <u>Exhibit C</u> (each a "<u>Settlement Document</u>"), setting forth the number of Shares to be purchased by the Investor, the applicable Conversion Price, the aggregate amount of accrued and unpaid interest due on the Promissory Note as of the Advance Date that shall be offset by the issuance of Shares, the aggregate principal amount of the Promissory Note as of the Advance Date that shall be offset by the issuance of Shares and the total principal amount of the Promissory Note that shall be outstanding following the Advance Notice Closing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) Promptly after receipt of the Settlement Document with respect to each Advance (and, in any event, not later than two Trading Days after such receipt), the Company will, or will cause its transfer agent to, electronically transfer such number of Shares to be purchased by the Investor (as set forth in the Settlement Document) by crediting the Investor's account or its designee's account at the Depository Trust Company through its Deposit Withdrawal at Custodian System or by such other means of delivery as may be mutually agreed upon by the parties hereto, and transmit notification to the Investor that such share transfer has been requested.
