            Issuance Date: August 5, 2022

    FOR VALUE RECEIVED, SANUWAVE
        Health, Inc., a corporation organized under the laws of Nevada (the “Company”), pursuant to this Future Advance Convertible Promissory Note (this “Note”) hereby promises to pay to          , its designee or registered assigns (the “Holder”) in cash and/or in shares of Common
        Stock (as defined in Section 26) the principal amount (as reduced pursuant to the terms hereof pursuant to redemption, conversion or otherwise, the “Principal”) as may be
        advanced in disbursements (each, a “Disbursement” and together, the “Disbursements” with total principal
        of outstanding Disbursements equaling Principal), and to pay interest at a rate of fifteen percent (15%) per annum (“Interest”) on any outstanding Principal at the applicable
        Interest Rate from the date of this Note until the Note is accelerated, converted, redeemed or otherwise (in each case in accordance with the terms hereof). Certain capitalized terms used herein are defined in Section 26. This Note is issued
        pursuant to that certain Securities Purchase Agreement, dated August 5, 2022, by and among the Company and the parties
          identified on the signature pages thereto (the “Purchase Agreement”), and capitalized terms not defined herein will have the meanings set forth in the Purchase
        Agreement.

    

    

    (1) PAYMENTS OF PRINCIPAL; PREPAYMENT. On the Disbursement Maturity Date, the Company
      shall pay to the Holder the applicable principal amount of the Disbursement in cash and/or shares of Common Stock and accrued and unpaid Interest on such Disbursement’s Principal and Interest.

     

    

    
      
        


    

    
    (2) INTEREST. Interest for each of the Disbursements under this Note shall commence
      accruing on the date hereof at the Interest Rate and shall be computed on the basis of a 360-day year and twelve 30-day months.  Accrued and unpaid Interest shall be payable on the Disbursement Maturity Date in cash by wire transfer of immediately
      available funds pursuant to wire instructions provided by the Holder in writing to the Company, shares of Common Stock or a combination thereof at the Holder’s discretion and if such date falls on a Holiday, the next day that is not a Holiday, to the
      record holder of this Note. Prior to the payment of Interest, Interest on this Note shall accrue at the Interest Rate and be payable by way of inclusion of the Interest in the Conversion Amount (as defined in Section 3(b)(i)).

    

    

    (3) CONVERSION OF NOTE. Following the Issuance Date, as set out above, this Note shall be
      convertible into shares of Common Stock on the terms and conditions set forth in this Section 3.

    

    

    (a) Optional Conversion Right. Subject to the provisions of Section 3(d), at any time or
      times on or after the Issuance Date of this Note, the Holder shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and nonassessable shares of Common Stock in accordance with Section 3(c), at the
      Conversion Rate (as defined below). 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 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. The
      Holder shall have the right to deliver an effective conversion notice in the form attached hereto as Exhibit I (each, a “Conversion Notice”)



      at any time until 11:59 p.m. (EST) on the chosen date and it shall be immediately effective.

    

    

    (b) Conversion Rate. The number of shares of Common Stock issuable upon conversion of any
      Conversion Amount pursuant to Section 3(a) shall be determined by dividing (x) such Conversion Amount by (y) the Conversion Price (the “Conversion Rate”).

    

    

    (i) “Conversion Amount” means the sum of (A) the portion
      of the Principal to be converted, redeemed or otherwise with respect to which this determination is being made and (B) accrued and unpaid Interest with respect to such Principal.

    

    

    (ii) “Conversion Price” shall be equal to $0.04, as
      adjusted pursuant to the terms of this Note.

    

    

    (c) Mechanics of Optional Conversion and Adjustment:

    

    

    (i)          Registration; Book-Entry. The Company shall maintain a register (the “Register”) for the recordation of the holder of
          the Note and the Principal amount of the Note (and stated interest thereon) held by the Holder (the “Registered Note”). The entries in the Register, made in good faith, shall
          be conclusive and binding for all purposes absent manifest error. The Company and the Holder shall treat each Person whose name is recorded in the Register as the owner of the Note for all purposes, including, without limitation, the right to
          receive payments of Principal and Interest, if any, hereunder, notwithstanding notice to the contrary. Upon its receipt of a request to assign or sell all or part of the Registered Note by the Holder, the Company shall record the information
          contained therein in the Register and issue one or more new Registered Notes in the same aggregate Principal amount as the Principal amount of the surrendered Registered Note to the designated assignee or transferee pursuant to Section 14.
          Notwithstanding anything to the contrary in this Section 3(c)(i), the Holder may assign any Note or any portion thereof to an Affiliate of such Holder or a Related Fund of such Holder without delivering a request to assign or sell such Note to
          the Company and the recordation of such assignment or sale in the Register; provided, that (x) the Company may continue to deal solely with such assigning or selling Holder unless and
          until such Holder has delivered a request to assign or sell such Note or portion thereof to the Company for recordation in the Register; (y) the failure of such assigning or selling Holder to deliver a request to assign or sell such Note or
          portion thereof to the Company shall not affect the legality, validity, or binding effect of such assignment or sale and (z) such assigning or selling Holder shall, acting solely for this purpose as a non-fiduciary agent of the Company, maintain
          a register (the “Related Party Register”) comparable to the Register on behalf of the Company, and any such assignment or sale shall be effective upon recordation of such
          assignment or sale in the Related Party Register. 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 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.

    

    

    
      2

      
        


    

    (ii) Registration Rights. This Note is issued pursuant to the terms
      of that certain Registration Rights Agreement dated August 5, 2022, by and among the Company, the Holder and the other parties thereto (the “Registration Rights Agreement”).

    

    

    (iii) Optional Repayment (“Optional Redemption”). At the Company’s option and upon thirty (30) days’ notice to the Holder (the “Optional Redemption Notice”), the Note may be redeemed at any time at an amount equal to one hundred and twenty-five percent (125%) of the outstanding Principal and accrued and unpaid Interest (the “Optional Redemption Price”). Such notice shall specify the date of such Optional Redemption (the “Optional Redemption
        Date”). The foregoing notwithstanding, the Holder may convert any or all of this Note into shares of Common Stock pursuant to the terms of this Section 3 at any time the Note remains outstanding.

    

    

    (d) Limitations on Conversions.

    

    

    (i) Beneficial Ownership. Notwithstanding anything to the contrary
      contained in this Note, this Note shall not be convertible by the Holder hereof, and the Company shall not effect any conversion of this Note or otherwise issue any shares of Common Stock pursuant hereto, to the extent (but only to the extent) that
      after giving effect to such conversion or other share issuance hereunder the Holder (together with the Holder’s Affiliates, and any other Persons acting as a Group together with the Holder or any of the Holder’s Affiliates (such Persons, “Attribution Parties”)) would beneficially own in excess of 4.99% (or upon election of the Holder, 9.99%) (the “Maximum



        Percentage”) of the Common Stock. To the extent the above limitation applies, the determination of whether this Note shall be convertible (vis-à-vis other convertible, exercisable or exchangeable securities owned by the Holder and its
      Affiliates and Attribution Parties) shall, subject to such Maximum Percentage limitation, be determined on the basis of the first submission to the Company for conversion, exercise or exchange (as the case may be). No prior inability to convert this
      Note, or to issue shares of Common Stock, pursuant to this paragraph shall have any effect on the applicability of the provisions of this paragraph with respect to any subsequent determination of convertibility. For purposes of this paragraph,
      beneficial ownership and all determinations and calculations (including, without limitation, with respect to calculations of percentage ownership) shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
      promulgated thereunder. The provisions of this paragraph shall be implemented in a manner otherwise than in strict conformity with the terms of this paragraph to correct this paragraph (or any portion hereof) which may be defective or inconsistent
      with the intended Maximum Percentage beneficial ownership limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such Maximum Percentage limitation. The limitations contained in this paragraph
      shall apply to a successor Holder of this Note. The holders of Common Stock shall be third party beneficiaries of this paragraph and the Company may not waive this paragraph without the consent of holders of a majority of its Common Stock. For any
      reason at any time, upon the written or oral request of the Holder, the Company shall within one (1) Business Day confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding, including by virtue of any prior
      conversion or exercise of convertible or exercisable securities into Common Stock, including, without limitation, pursuant to this Note or securities issued pursuant to the Purchase Agreement.

    

    

    
      3

      
        


    

    

    

    (ii) Principal Market Regulation. Unless permitted by the applicable
      rules and regulations of the Principal Market, the Company shall not issue any shares of Common Stock upon conversion of this Note if the issuance of such shares of Common Stock would exceed the aggregate number of shares of Common Stock which the
      Company may issue upon exercise or conversion (as the case may be) of the Note without breaching the Company’s obligations under the rules or regulations of the Principal Market (the number of shares which may be issued without violating such rules
      and regulations, the “Exchange Cap”). Notwithstanding the foregoing, such limitation shall not apply in the event that the Company (A) obtains the approval of its stockholders as
      required by the applicable rules of the Principal Market for issuances of shares of Common Stock in excess of such amount or (B) obtains a written opinion from outside counsel to the Company that such approval is not required, which opinion shall be
      reasonably satisfactory to the Holder. In the event that any Holder shall sell or otherwise transfer any of such Holder’s Note, the Exchange Cap restrictions set forth herein shall continue to apply to the Note and such transferee.

    

    

    (iii) No Conversion until Sufficient Authorized and Unissued Shares Available. 



      Notwithstanding anything herein to the contrary, this Note shall not be convertible into shares of Common Stock of the Company until such time as the Company’s authorized and unissued shares of Common Stock are at a number sufficient to permit the
      conversion of this Note and the conversion or exercise, as applicable, of all other outstanding securities of the Company convertible into or exercisable for shares of Common Stock of the Company.

    

    

                                           (e) Disputes. In the event of a dispute as to the number of shares of
      Common Stock issuable to the Holder in connection with a conversion of this Note, the Company shall issue to the Holder the number of shares of Common Stock not in dispute and resolve such dispute in accordance with Section 19.

    

    

    (4) [RESERVED.]

    

    

    (5) RIGHTS UPON EVENT OF DEFAULT.

    

    

                                          (a) Event of Default. Each of the following events shall constitute an
      “Event of Default”; provided, however, that, except in the case of the Events of Default listed in
      Sections 5(a)(i), 5(a)(ix) or 5(a)(xxiv) below, the Company shall have five (5) Business Days after notice of default from the Holder to cure such Event of Default unless a lesser number of days is required pursuant to the provisions of this Section
      5.

    

    

    
      4

      
        


    

    (i) Failure to Pay Principal or Interest. The Company fails to pay
      the Principal or Interest due at the Disbursement Maturity Date, liquidated damages and other amounts thereon when due on the Note whether at maturity, upon acceleration or otherwise.

    

    

    (ii) Conversion and the Shares. The Company (i) fails to issue
      Conversion Shares to the Holder (or announces or threatens in writing that it will not honor its obligation to do so) upon exercise by the Holder of the conversion rights of the Holder in accordance with the terms of the Note, (ii) fails to transfer
      or cause its transfer agent to transfer (issue) (electronically or in certificated form) any certificate for the Conversion Shares issuable to the Holder upon conversion of or otherwise pursuant to the Note as and when required by the Note, or (iii)
      the Company directs its transfer agent not to transfer or delays, impairs, and/or hinders its transfer agent in transferring (or issuing) (electronically or in certificated form) any certificate for the Conversion Shares issuable to the Holder upon
      conversion of or otherwise pursuant to the Note as and when required by the Note, or fails to remove (or directs its transfer agent not to remove or impairs, delays, and/or hinders its transfer agent from removing) any restrictive legend (or to
      withdraw any stop transfer instructions in respect thereof) on any certificate for any Conversion Shares issued to the Holder upon conversion of or otherwise pursuant to the Note as and when required by the Note (or makes any written announcement,
      statement or threat that it does not intend to honor the obligations described in this paragraph) and any such failure shall continue uncured (or any written announcement, statement or threat not to honor its obligations shall not be rescinded in
      writing) for five (5) Business Days after the Holder shall have delivered a Conversion Notice. It is an obligation of the Company to remain current in its obligations to its transfer agent. It shall be an Event of Default of the Note, if a conversion
      of the Note is delayed, hindered or frustrated due to a balance owed by the Company to its transfer agent. If at the option of the Holder, the Holder advances any funds to the Company’s transfer agent in order to process a conversion, such advanced
      funds shall be paid by the Company to the Holder within forty-eight (48) hours of a demand from the Holder. If Borrower is unable to do so, they shall have an opportunity to cure within five (5) Business Days.

    

    

    (iii) Breach of Agreements and Covenants. The Company breaches any
      material agreement, covenant or other material term or condition contained in the Transaction Documents, and such breach results in a Material Adverse Effect on the business or assets of the Company; for the avoidance of doubt a failure of the
      Company to file a registration statement by the  “Filing Date” and have the same declared effective by the “Effectiveness Date” as provided in the Registration Rights Agreement will constitute a breach of a material agreement that results in a
      Material Adverse Effect on the business of the Company for purposes of this Note and the Purchase Agreement.

    

    

    (iv) Breach of Representations and Warranties. Any representation or
      warranty of the Company made in the Purchase Agreement or the Note, or in any agreement, statement or certificate given in writing pursuant hereto or in connection herewith or therewith shall be false or misleading in any material respect when made
      and the breach of which has (or with the passage of time will have) a Material Adverse Effect on the rights of the Holder with respect to the Note or the Purchase Agreement. In the event of such a breach, the Company shall have an opportunity to cure
      within five (5) Business Days.

    

    

    (v) Receiver or Trustee. The Company or any subsidiary of the Company
      shall make an assignment for the benefit of creditors, or apply for or consent to the appointment of a receiver or trustee for it or for a substantial part of its property or business, or such a receiver or trustee shall otherwise be appointed. Under
      such circumstances, the Company shall have an opportunity to cure within sixty (60) calendar days.

     

    

    
      5

      
        


    

    (vi) Judgments. Any money judgment, writ or similar process shall be
      entered or filed against the Company or any subsidiary of the Company or any of its property or other assets for more than $1,000,000 and shall remain unvacated, unbonded or unstayed for a period of twenty (20) calendar days unless otherwise
      consented to by the Holder, which consent will not be unreasonably withheld, conditioned or delayed.

    

    

    (vii) Bankruptcy. Bankruptcy, insolvency, reorganization or
      liquidation proceedings or other proceedings, voluntary or involuntary, for relief under any bankruptcy law or any law for the relief of debtors shall be instituted by or against the Company or any subsidiary of the Company. Under such circumstances,
      the Company shall have an opportunity to cure within sixty (60) calendar days.

    

    

    (viii) Delisting or Trading of Common Stock. The Company shall fail
      to maintain the listing or quotation of its Common Stock minimally on a Trading Market, which shall include the OTC pink sheets pro-rata based on the entire amount raised.

    

    

    (ix) Failure to Comply with the Exchange Act.  After the date hereof,
      the Company shall (a) fail to file all Form 10-Qs and Form 10-Ks within the time periods required by the Exchange Act or (b) cease to be subject to the reporting requirements of the Exchange Act.

    

    

    (x) Liquidation. Any dissolution, liquidation, or winding up of the
      Company or any substantial portion of its business or assets.

    

    

    (xi) Cessation of Operations. Any cessation of operations by the
      Company or the Company admits it is otherwise generally unable to pay its debts as such debts become due; provided, however, that any disclosure of the Company’s ability to continue as a “going concern” shall not be an admission that the Company
      cannot pay its debts as they become due.

    

    

    (xii) Reverse Stock Split.  The Company fails to reduce its
      outstanding shares via a reverse stock split to provide a number of authorized and unissued shares of Common Stock sufficient to permit the conversion of this Note and the conversion or exercise, as applicable, of all other outstanding securities of
      the Company convertible into or exercisable for shares of Common Stock of the Company on or before December 31, 2022.

    

    

    (xiii) Depository Trust Company (“DTC”) “Chill”. The DTC places a
      “chill” (i.e., a restriction placed by DTC on one or more of DTC’s services, such as limiting a DTC participant’s ability to make a deposit or withdrawal of the security at DTC) on any of the Company’s securities. In the event of such a breach, the
      Company shall have an opportunity to cure within twenty (20) Business Days.

    

    

    (xiv) [Reserved.]

    

    

    (xv) Default under Transaction Documents or Other Material Agreement.
      Other than those defaults or events of default previously disclosed by the Company in its SEC Reports (including any defaults and events of default that are continuing on and after the date hereof), including information contained or incorporated by
      reference therein as of the date hereof, a default or event of default (subject to any grace or cure period provided in the applicable agreement, document or instrument) shall occur under any Transaction Document or material agreement (which shall
      include, without limitation, all agreements filed with the SEC Reports), lease, document or instrument to which the Company or any Subsidiary is obligated and is identified in the Company’s Form 10-K or other Exchange Act filings, which results in a
      Material Adverse Effect.

    

    

    
      6

      
        


    

    (xvi) [Reserved.]

    

    

    (xvii) [Reserved.]

    

    

    (xviii) Failure to Meet the Requirements under Rule 144. The Company
      does not meet the current public information requirements under Rule 144.

    

    

    (xix) Failure to Maintain Intellectual Property. The failure by the
      Company or any material Subsidiary to maintain any material intellectual property rights, personal, real property, equipment, leases or other assets which are necessary to conduct its business (whether now or in the future) and such breach is not
      cured with twenty (20) calendar days after written notice to the Company from the Holder.

    

    

    (xx) Trading Suspension. An SEC or judicial stop trade order or
      suspension from a Trading Market.

    

    

    (xxi) Restatement of Financial Statements. The restatement after the
      date hereof of any financial statements filed by the Company with the SEC for any date or period from two years prior to the Issuance Date and until this Note is no longer outstanding, if the result of such restatement would, by comparison to the
      unrestated financial statements, have constituted a Material Adverse Effect. For the avoidance of doubt, any restatement related to new accounting pronouncements shall not constitute a default under this Section.

    

    

    (xxii) [Reserved.]

    

    

    (xxiii) Invalidity or Unenforceability of Transaction Documents. Any
      material provision of any Transaction Document shall at any time for any reason (other than pursuant to the express terms thereof) cease to be valid and binding on or enforceable against the Company, or the validity or enforceability thereof shall be
      contested by the Company, or a proceeding shall be commenced by the Company or any governmental authority having jurisdiction over the Company or the Holder, seeking to establish the invalidity or unenforceability thereof, or the Company shall deny
      in writing that it has any liability or obligation purported to be created under any Transaction Document.

    

    

    (xxiv) Effective Registration Statement. Failure to comply with the
      Registration Rights Agreement or Purchase Agreement.

    

    

                                            (b) Redemption Right. At any time after the Holder becoming aware of
      an Event of Default, the Holder may require the Company to redeem (an “Event of Default Redemption”) all or any portion of this Note by delivering written notice thereof (the “Event of Default Redemption Notice”) to the Company, which Event of Default Redemption Notice shall indicate the portion of this Note the Holder is electing to require the Company to
      redeem and the date of such Event of Default Redemption (the “Event of Default Redemption Date”). Each portion of this Note subject to redemption by the Company pursuant to this
      Section 5(b) shall be redeemed by the Company in cash by wire transfer of immediately available funds at a price equal to Principal plus accrued and unpaid Interest calculated from the Event of Default at the Default Interest Rate (the “Event of Default Redemption Price”) together with liquidated damages of $250,000 pro-rata based on the entire
      amount raised plus an amount in cash equal to 1% of the Event of Default Redemption Price for each 30 day period during which redemptions fail to be made with a cap at 5%. Redemptions required by this Section 5(b) shall be made in accordance with the
      provisions of Section 10. To the extent an Event of Default Redemption is deemed or determined by a court of competent jurisdiction to be a prepayment of the Note by the Company, such redemption shall be deemed to be a voluntary prepayment.
      Notwithstanding anything to the contrary in this Section 5, but subject to Section 3(b)(ii) and 3(d), until the Event of Default Redemption Price (together with any interest thereon) is paid in full, the Conversion Amount submitted for redemption
      under this Section 5(b) (together with any interest thereon) may be converted, in whole or in part, by the Holder into Common Stock pursuant to Section 3. The parties hereto agree that in the event of the Company’s redemption of any portion of the
      Note under this Section 5(b), the Holder’s damages would be uncertain and difficult to estimate because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable substitute investment opportunity
      for the Holder. Accordingly, any Event of Default Redemption Price due under this Section 5(b) is intended by the parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not as a
      penalty.

    
      7

      
        


    

    

    

    (6) RIGHTS UPON FUNDAMENTAL TRANSACTION. If, at any time while this
      Note is outstanding, the Company effects a Fundamental Transaction, then, upon any subsequent conversion of this Note, the Holder shall have the right to receive, for each Conversion Share that would have been issuable upon such conversion
      immediately prior to the occurrence of such Fundamental Transaction, the same kind and amount of securities, cash or property as it would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately
      prior to such Fundamental Transaction, the holder of one (1) share of Common Stock (the “Alternate Consideration”). For purposes of any such conversion, the determination of the Conversion
      Price shall be appropriately adjusted to apply to such Alternate Consideration based on the amount of Alternate Consideration issuable in respect of one (1) share of Common Stock in such Fundamental Transaction, and the Company shall apportion the
      Conversion Price among the Alternate Consideration in a reasonable manner reflecting the relative value of any different components of the Alternate Consideration. If holders of Common Stock are given any choice as to the securities, cash or property
      to be received in a Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any conversion of this Note following such Fundamental Transaction. To the extent necessary to effectuate
      the foregoing provisions, any Successor Entity or Successor Entities to the Company or surviving entity in such Fundamental Transaction shall issue to the Holder a new Note consistent with the foregoing provisions and evidencing the Holder’s right to
      convert such Note into Alternate Consideration. The terms of any agreement pursuant to which a Fundamental Transaction is effected shall include terms requiring any such Successor Entity or Successor Entities to comply with the provisions of this
      Section 6 and insuring that this Note (or any such replacement security) will be similarly adjusted upon any subsequent transaction analogous to a Fundamental Transaction.

     

    

    (7) DISTRIBUTION OF ASSETS; RIGHTS UPON ISSUANCE OF PURCHASE RIGHTS AND OTHER CORPORATE EVENTS.

    

    

                                       (a) Distribution of Assets. If the Company shall declare or make any
      dividend or other distributions of its assets (or rights to acquire its assets) to any or all holders of shares of Common Stock, by way of return of capital or otherwise (including without limitation, any distribution of cash, stock or other
      securities, property, options, evidence of Indebtedness or any other assets by way of a dividend, spin off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction) (the “Distributions”), then the Holder will be entitled to such Distributions as if the Holder had held the number of shares of Common Stock acquirable upon complete conversion of this Note (without taking into account
      any limitations or restrictions on the convertibility of this Note) immediately prior to the date on which a record is taken for such Distribution or, if no such record is taken, the date as of which the record holders of Common Stock are to be
      determined for such Distribution and the portion of such Distribution shall be held in abeyance for the Holder until such time or times as its right thereto would not result in the Holder and its Affiliates and Attribution Parties exceeding the
      Maximum Percentage, at which time or times the Holder shall be granted such rights (and any rights under this Section 7(a) on such initial rights or on any subsequent such rights to be held similarly in abeyance) to the same extent as if there had
      been no such limitation.

    

    

    
      8

      
        


    

                                           (b) Purchase Rights. If at any time the Company grants, issues or
      sells any Options, Convertible Securities or rights to purchase stock, warrants, securities or other property pro rata to the record holders of any class of Common Stock (the “Purchase
        Rights”), then the Holder will be entitled to acquire or receive, as applicable, upon the terms applicable to such Purchase Rights, the aggregate Purchase Rights which the Holder could have acquired if the Holder had held the number of
      shares of Common Stock acquirable upon complete conversion of this Note (without taking into account any limitations or restrictions on the convertibility of this Note) immediately prior to the date on which a record is taken for the grant, issuance
      or sale of such Purchase Rights, or, if no such record is taken, the date as of which the record holders of shares of Common Stock are to be determined for the grant, issue or sale of such Purchase Rights (provided, however, that to the extent that the Holder’s right to participate in any such Purchase Right would result in the Holder and its Affiliates and
      Attribution Parties exceeding the Maximum Percentage, then the Holder shall not be entitled to participate in such Purchase Right to such extent (and shall not be entitled to beneficial ownership of such shares of Common Stock as a result of such
      Purchase Right (and beneficial ownership) to such extent) and such Purchase Right to such extent shall be held in abeyance for the Holder until such time or times as its right thereto would not result in the Holder and its Affiliates and Attribution
      Parties exceeding the Maximum Percentage, at which time or times the Holder shall be granted such right (and any Purchase Right granted, issued or sold on such initial Purchase Right or on any subsequent Purchase Right to be held similarly in
      abeyance) to the same extent as if there had been no such limitation).

    

    

                                           (c) Other Corporate Events. In addition to and not in substitution
      for any other rights hereunder, prior to the occurrence or consummation of any Fundamental Transaction pursuant to which holders of shares of Common Stock are entitled to receive securities, cash, assets or other property with respect to or in
      exchange for shares of Common Stock (a “Corporate Event”), the Company shall make appropriate provision to ensure that, and any applicable Successor Entity or Successor Entities
      shall ensure that, and it shall be a required condition to the occurrence or consummation of such Corporate Event that, the Holder will thereafter have the right to receive upon conversion of this Note at any time after the occurrence or consummation
      of the Corporate Event, shares of Common Stock or capital stock of the applicable Successor Entity or Successor Entities or, if so elected by the Holder, cash in lieu of the shares of Common Stock (or other securities, cash, assets or other property)
      purchasable upon the conversion of this Note prior to such Corporate Event, such shares of stock, securities, cash, assets or any other property whatsoever (including warrants or other purchase or subscription rights and any shares of Common Stock)
      which the Holder would have been entitled to receive upon the occurrence or consummation of such Corporate Event or the record, eligibility or other determination date for the event resulting in such Corporate Event, had this Note been converted
      immediately prior to such Corporate Event or the record, eligibility or other determination date for the event resulting in such Corporate Event (without regard to any limitations on conversion of this Note). Provision made pursuant to the preceding
      sentence shall be in a form and substance satisfactory to the Holder. The provisions of this Section 7 shall apply similarly and equally to successive Corporate Events.

    

    

                                 (8)      RIGHTS UPON ISSUANCE OF OTHER SECURITIES.

    

    

                                          (a) Adjustment of Conversion Price upon Subdivision or Combination of Common
          Stock. If the Company at any time on or after the Issuance Date subdivides (by any stock split, stock dividend, recapitalization or otherwise), one or more classes of 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; provided, however, that the Conversion Price pursuant to this Section 8(a) shall never be less than $0.01. If the Company at any time on or
      after the Issuance Date combines (by combination, reverse stock split or otherwise) one or more classes of 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.

    

    

    
      9

      
        


    

                                          (b) Adjustment Upon Issuance of Shares of Common Stock. If and
      whenever on or after the date hereof, the Company issues or sells, or in accordance with this Section 8(b) is deemed to have issued or sold, any shares of Common Stock (including the issuance or sale of shares of Common Stock owned or held by or for
      the account of the Company, but excluding any Exempt Issuance issued or sold or deemed to have been issued or sold) for a consideration per share (the “New Issuance Price”) less
      than a price equal to the Conversion Price in effect immediately prior to such issue or sale or deemed issuance or sale (such Conversion Price then in effect is referred to as the “Applicable



        Price”) (the foregoing a “Dilutive Issuance”), then immediately after such Dilutive Issuance, the Conversion Price then in effect shall be reduced to the New Issuance
      Price; provided, however, that the Conversion Price pursuant to this Section 8(b) shall never be less than $0.01. For all purposes of the foregoing (including, without limitation, determining the adjusted Conversion Price and consideration per share
      under this Section 8(b)), the following shall be applicable:

    

    

    (i) Issuance of Options. If the Company in any manner grants or sells
      any Options (other than Options that qualify as Exempt Issuances) and the lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Option or upon conversion, exercise or exchange of any Convertible
      Securities issuable upon exercise of any such Option is less than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the granting or sale of such
      Option for such price per share. For purposes of this Section 8(b)(i), the “lowest price per share for which one share of Common Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible
      Securities issuable upon exercise of any such Option” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any) received or receivable by the Company with respect to any one share of Common Stock upon the granting
      or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option and (y) the lowest exercise price set forth in such Option for which one share of Common
      Stock is issuable upon the exercise of any such Options or upon conversion, exercise or exchange of any Convertible Securities issuable upon exercise of any such Option minus (2) the sum of all amounts paid or payable to the holder of such Option (or
      any other Person) upon the granting or sale of such Option, upon exercise of such Option and upon conversion, exercise or exchange of any Convertible Security issuable upon exercise of such Option plus the value of any other consideration received or
      receivable by, or benefit conferred on, the holder of such Option (or any other Person). Except as contemplated below, no further adjustment of the Conversion Price shall be made upon the actual issuance of such shares of Common Stock or of such
      Convertible Securities upon the exercise of such Options or upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities.

    

    

    
      10

      
        


    

    (ii) Issuance of Convertible Securities. If the Company in any manner
      issues or sells any Convertible Securities (other than Convertible Securities that qualify as Exempt Issuances) and the lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof is less
      than the Applicable Price, then such share of Common Stock shall be deemed to be outstanding and to have been issued and sold by the Company at the time of the issuance or sale of such Convertible Securities for such price per share. For the purposes
      of this Section 8(b)(ii), the “lowest price per share for which one share of Common Stock is issuable upon the conversion, exercise or exchange thereof” shall be equal to (1) the lower of (x) the sum of the lowest amounts of consideration (if any)
      received or receivable by the Company with respect to one share of Common Stock upon the issuance or sale of the Convertible Security and upon conversion, exercise or exchange of such Convertible Security and (y) the lowest conversion price set forth
      in such Convertible Security for which one share of Common Stock is issuable upon conversion, exercise or exchange thereof minus (2) the sum of all amounts paid or payable to the holder of such Convertible Security (or any other Person) upon the
      issuance or sale of such Convertible Security plus the value of any other consideration received or receivable by, or benefit conferred on, the holder of such Convertible Security (or any other Person). Except as contemplated below, no further
      adjustment of the Conversion Price shall be made upon the actual issuance of such shares of Common Stock upon conversion, exercise or exchange of such Convertible Securities, and if any such issue or sale of such Convertible Securities is made upon
      exercise for which adjustment of this Note has been or is to be made pursuant to other provisions of this Section 8(b)(ii), except as contemplated below, no further adjustment of the Conversion Price shall be made by reason of such issue or sale.

    

    

    (iii) Change in Option Price or Rate of Conversion. If the purchase
      or exercise price provided for in any Options, the additional consideration, if any, payable upon the issue, conversion, exercise or exchange of any Convertible Securities, or the rate at which any Convertible Securities are convertible into or
      exercisable or exchangeable for shares of Common Stock increases or decreases at any time, the Conversion Price in effect at the time of such increase or decrease shall be adjusted to the Conversion Price which would have been in effect at such time
      had such Options or Convertible Securities provided for such increased or decreased purchase price, additional consideration or increased or decreased conversion rate, as the case may be, at the time initially granted, issued or sold. For purposes of
      this Section 8(b)(iii), if the terms of any Option or Convertible Security that was outstanding as of the date of issuance of this Note are increased or decreased in the manner described in the immediately preceding sentence, then such Option or
      Convertible Security and the shares of Common Stock deemed issuable upon exercise, conversion or exchange thereof shall be deemed to have been issued as of the date of such increase or decrease. No adjustment pursuant to this Section 8(b) shall be
      made if such adjustment would result in an increase of the Conversion Price then in effect.

    

    

    (iv) Calculation of Consideration Received. If any Option and/or
      Convertible Security is issued in connection with the issuance or sale or deemed issuance or sale of any other securities of the Company (as determined by the Holder, the “Primary Security,”
      and such Option and/or Convertible Security, the “Secondary Securities”), together comprising one integrated transaction, the consideration per share of Common Stock with respect to such
      Primary Security shall be deemed to be equal to the difference of (x) the lowest price per share for which one share of Common Stock was issued in such integrated transaction (or was deemed to be issued pursuant to Section 8(b)(i) or 8(b)(ii) above,
      as applicable) solely with respect to such Primary Security, minus (y) with respect to such Secondary Securities, the fair market value of such Secondary Securities as agreed to by the Company and the Holder and absent such agreement by an
      independent, reputable appraiser jointly selected by the Company and the Holder. The determination of such appraiser shall be final and binding upon all parties absent manifest error and the fees and expenses of such appraiser shall be borne by the
      Company.

    

    

    (c) Company Conversion Right and Adjustment of Conversion Price Upon Listing. 
        If the Company lists its shares of Common Stock on the Nasdaq Capital Market, then, upon the approval of the Board of Directors, all Principal and accrued and
        unpaid Interest under this Note shall automatically convert into Common Stock at the then effective Conversion Price.  Notwithstanding the foregoing, if, for the five (5) Trading Day period immediately prior
        to such approval by the Board of Directors, the average VWAP of the listed Common Stock (the “Post-Listing Threshold Price”) is less than $0.04 per share (as adjusted for any reverse stock
          split, stock split, dividend or other distribution, recapitalization or similar event with respect to the Common Stock that occurs after the date hereof), then the Conversion Price then in effect shall be reduced to the greater of (i) the
        Post-Listing Threshold Price and (ii) $0.01.

    

    

    
      11

      
        


    

    (d) Calculations. All calculations under this Section 8 shall be made to the nearest
      cent or the nearest 1/100th of a share, as the case may be. For purposes of this Section 8, the number of shares of Common Stock deemed to be issued and outstanding as of a given date shall be the sum of the number of shares of Common Stock
      (excluding any treasury shares of Company) issued and outstanding.

    

    

    (e) Notice to the Holder.

     

        

    (i) Adjustment to Conversion Price. Whenever the Conversion Price is
      adjusted pursuant to any provision of this Section 8, the Company shall provide to each Holder a notice setting forth the Conversion Price after such adjustment and setting forth a brief statement of the facts requiring such adjustment within two (2)
      Business Days of such event.

    

    

    (ii) Notice to Allow Conversion by Holder. If (A) Company shall
      declare a dividend (or any other distribution in whatever form) on the Common Stock, (B) the Company shall declare a special nonrecurring cash dividend on or a redemption of the Common Stock, (C) the Company shall authorize the granting to all
      holders of the Common Stock of rights or warrants to subscribe for or purchase any shares of capital stock of any class or of any rights, (D) the approval of any stockholders of the Company shall be required in connection with any reclassification of
      the Common Stock, any consolidation or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any compulsory share exchange whereby the Common Stock is converted into other
      securities, cash or property or (E) the Company shall authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case, the Company shall cause to be filed at each office or agency
      maintained for the purpose of conversion of this Note, and shall cause to be delivered to the Holder at its last address as it shall appear upon the Note Register, at least twenty (20) calendar days prior to the applicable record or effective date
      hereinafter specified, a notice stating (x) the date on which a record is to be taken for the purpose of such dividend, distribution, redemption, rights or warrants, or if a record is not to be taken, the date as of which the holders of the Common
      Stock of record to be entitled to such dividend, distributions, redemption, rights or warrants are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or share exchange is expected to become
      effective or close, and the date as of which it is expected that holders of the Common Stock of record shall be entitled to exchange their shares of the Common Stock for securities, cash or other property deliverable upon such reclassification,
      consolidation, merger, sale, transfer or share exchange, provided that the failure to deliver such notice or any defect therein or in the delivery thereof shall not affect the validity of the corporate action required to be specified in such notice.
      To the extent that any notice provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries, the Company shall simultaneously file such notice with the SEC pursuant to a Current Report
      on Form 8-K. The Holder shall remain entitled to convert this Note during the 20-day period commencing on the date of such notice through the effective date of the event triggering such notice except as may otherwise be expressly set forth herein.

    

    

    (f) Voluntary Adjustment by Company. The Company may at any time during the term of this
      Note, with the prior written consent of each Holder so affected, reduce the then current Conversion Price to any amount and for any period of time deemed appropriate by the Board of Directors of the Company.

    

    

    
      12

      
        


    

    (9) NONCIRCUMVENTION. The Company hereby covenants and agrees that the Company will not,
      by amendment of its Articles of Incorporation, Bylaws or through any reorganization, transfer of assets, consolidation, merger, scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the
      observance or performance of any of the terms of this Note, and will at all times in good faith carry out all of the provisions of this Note and take all action as may be required to protect the rights of the Holder of this Note.

    

    

    (10) REDEMPTIONS. In the case of a redemption, the Company shall deliver the Event of
      Default Redemption Price or the Optional Redemption Price to the Holder on or prior to the Event of Default Redemption Date or the Optional Redemption Date, respectively. The Company shall pay the applicable Event of Default Redemption Price or
      Optional Redemption Price to the Holder in cash by wire transfer of immediately available funds pursuant to wire instructions provided by the Holder in writing to the Company on the applicable due date. In the event of a redemption of less than all
      of the Conversion Amount of this Note, the Company shall promptly cause to be issued and delivered to the Holder a new Note (in accordance with Section 14(d)) representing the outstanding Principal which has not been redeemed and any accrued Interest
      on such Principal which shall be calculated as if no Redemption Notice had been delivered. In the event that the Company does not pay the applicable Redemption Price to the Holder within the time period required, at any time thereafter and until the
      Company pays such unpaid Redemption Price in full, the Holder shall have the option, in lieu of redemption, to require the Company to promptly return to the Holder all or any portion of this Note representing the Conversion Amount that was submitted
      for redemption and for which the applicable Redemption Price has not been paid. Upon the Company’s receipt of such notice, (x) the applicable Redemption Notice shall be null and void with respect to such Conversion Amount, (y) the Company shall
      immediately return this Note, or issue a new Note (in accordance with Section 14(d)) to the Holder representing such Conversion Amount to be redeemed and (z) the Conversion Price of this Note or such new Notes shall be adjusted to the lesser of (A)
      the Conversion Price as in effect on the date on which the applicable Redemption Notice is voided and (B) the lowest Closing Bid Price of the Common Stock during the period beginning on and including the date on which the applicable Redemption Notice
      is delivered to the Company and ending on and including the date on which the applicable Redemption Notice is voided; provided, however, that in no event shall the Conversion Price be a price less than the Market Price.

    

    

    (11) VOTING RIGHTS. The Holder shall have no voting rights as the holder of this Note,
      except as required by law and as expressly provided in this Note.

    

    

    (12) COVENANTS.

     

        

    (a) Incurrence of Indebtedness. So long as this Note is outstanding, the Company shall
      not, and the Company shall not permit any of its Subsidiaries to, directly or indirectly, incur or guarantee, assume or suffer to exist any Indebtedness, other than Permitted Indebtedness.

    

    

    (b) Existence of Liens. So long as this Note is outstanding, the Company shall not, and
      the Company shall not permit any of its Subsidiaries to, directly or indirectly, allow or suffer to exist any Liens other than Permitted Liens.

    

    

    (c) Change in Nature of Business. The Company shall not make, or permit any of its
      Subsidiaries to make, any change in the nature of its business as described in the Company's most recent Annual Report filed on Form 10-K with the SEC. The Company shall not modify its corporate structure or purpose.

      each of its Subsidiaries to maintain and preserve, its existence, rights and privileges, and become or remain, and cause each of its Subsidiaries to become or remain, duly qualified and in good standing in each jurisdiction in which the character of
      the properties owned or leased by it or in which the transaction of its business makes such qualification necessary.

    

    

    (f) Maintenance of Properties, Etc. The Company shall maintain and preserve, and cause
      each of its Subsidiaries to maintain and preserve, all of its properties which are necessary or useful in the proper conduct of its business in good working order and condition, ordinary wear and tear excepted, and comply, and cause each of its
      Subsidiaries to comply, at all times with the provisions of all leases to which it is a party as lessee or under which it occupies property, so as to prevent any loss or forfeiture thereof or thereunder.

      business practice by companies in similar businesses similarly situated.

    

    

    (h) Transactions with Affiliates. The Company shall not, nor shall it permit any of its
      Subsidiaries to, enter into, renew, extend or be a party to, any transaction or series of related transactions (including, without limitation, the purchase, sale, lease, transfer or exchange of property or assets of any kind or the rendering of
      services of any kind) with any Affiliate, except for Permitted Indebtedness or in the ordinary course of business in a manner and to an extent consistent with past practice and necessary or desirable for the prudent operation of its business, for
      fair consideration and on terms no less favorable to it or its Subsidiaries than would be obtainable in a comparable arm’s length transaction with a Person that is not an Affiliate thereof.

    

    

    (i) Corporate Changes. The Company shall not change its corporate name, legal form or
      jurisdiction of formation without twenty (20) calendar days’ prior written notice to Holder. The Company shall not enter into or be party to a Fundamental Transaction unless in accordance with Section 6 hereof. The Company shall not relocate its
      chief executive office or its principal place of business unless it has provided prior written notice to the Holder.

    

    

    (j) [Reserved.]

    

    

    (k) Charter Amendments.  The Company shall not amend its charter documents, including,
      without limitation, its Articles of Incorporation and Bylaws, in any manner that materially and adversely affects any rights of the Holder.

      pro-rata basis), whether by way of payment in respect of principal of (or premium, if any) or interest on, such Indebtedness; the foregoing restriction shall not apply to Permitted Indebtedness except upon the occurrence of an Event of Default.

    

    

    
      14

      
        


    

    (n) Declaration. The Company shall not declare or make any dividend or other
      distribution of its assets or rights to acquire its assets to holders of shares of Common Stock, by way of return of capital or otherwise including, without limitation, any distribution of cash, stock or other securities, property or options by way
      of a dividend, spin-off, reclassification, corporate rearrangement, scheme of arrangement or other similar transaction.

    

    

    (13) TRANSFER. This Note and any shares of Common Stock issued upon conversion of this
      Note may be offered, sold, assigned or transferred according to the Purchase Agreement.

    

    

    (14) REISSUANCE OF THIS NOTE.

    

    

    (a) Transfer. If this Note is to be transferred, the Holder shall instruct the Company
      who the new Holder will be, and this Note will be automatically cancelled.   The Company will issue and deliver the new Note within two (2) Business Days of such notice.

    

    

    (b) Lost, Stolen or Mutilated Note. 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 14(d)) representing the then outstanding Principal amount of the Note.

    

    

    (c) Note Exchangeable for Different Denominations. 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 14(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.

    

    

    (d) Issuance of New Notes. 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
      14(a) or Section 14(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 Notes), (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 on the Principal and Interest of this Note, from the Issuance Date.

    

    

    (15) REMEDIES, CHARACTERIZATIONS, OTHER OBLIGATIONS, BREACHES AND INJUNCTIVE RELIEF. The
      remedies provided in this Note shall be cumulative and in addition to all other remedies available under this Note and any of the other Transaction Documents, at law or in equity (including a decree of specific performance and/or other injunctive
