        permitted assigns, “Agent”), the Holders from time to time signatory to the NPA (as hereinafter defined), including North Haven Expansion (each, a “Holder” and collectively, the “Holders”), and SANUWAVE HEALTH, INC. a Nevada corporation (“Issuer”).

       

      RECITALS

       

      WHEREAS, Issuer, Agent and the Holders are parties to that certain Note and Warrant Purchase and Security Agreement dated as of August 6, 2020 (as
        amended, restated, amended and restated, supplemented or otherwise modified from time to time, the “NPA”).

       

      WHEREAS, Issuer is in default of the NPA as described below;

       

      WHEREAS, Issuer has requested that Agent and the Holders amend the NPA to (i) forbear from exercising remedies under the NPA as a result of the

      WHEREAS, Agent and the Holders have agreed to so amend certain provisions of the NPA, and to so forbear from exercising Agent’s and the Holders’
        rights and remedies during the Forbearance Period (as defined below), but only to the extent in accordance with the terms, subject to the conditions and in reliance upon the representations and warranties set forth below; and

          modified from time to time, the “Second Closing Warrant”).

       

      3.          A new Section 5.2(h) hereby is added to the NPA to read as follows:

          requirements and not for personal, family, household or agricultural purposes, (ii) to repay the Existing Indebtedness in full on the Issue Date, (iii) to finance a portion of the Celularity Acquisition and (iv) in the case of proceeds of the
          Second Closing Note, in accordance with a budget for the projected use of the proceeds from and after the Second Amendment Effective Date, as reviewed and approved in writing by Agent (the “Budgeted Use of
            Proceeds”).”

       

      5.           Section 11.6 of the NPA hereby is renumbered to “11.6.1,” and re-titled “Purchase Price Allocation – First Closing Note;”
          and a new Section 11.6.2 hereby is added to the NPA to read as follows:

          Thousand Five Hundred Sixteen Dollars $(2,043,516) and that, pursuant to Treas.  Reg.  § 1.1273-2(h), Two Million Forty-Three Thousand Five Hundred Sixteen Dollars $(2,043,516) of the issue price of the investment unit will be allocable to such
          Second Closing Warrant and the balance shall be allocable to such Second Closing Note.  Issuer and each Holder agree to prepare their federal income tax returns in a manner consistent with the foregoing.  Issuer agrees that it shall not (and
          shall cause its Subsidiaries not to) challenge or support any challenge to the agreed-upon value of such Second Closing Warrant.”

        Ninety-Three (20,666,993) shares of Issuer’s common stock, issued without cost to Agent, as a result of Agent’s role as an advisor to Issuer.

       

      “Budgeted Use of Proceeds” has the meaning ascribed in Section 5.9.

      7.           Schedule 1.1 to the NPA hereby is replaced in its entirety with Schedule 1.1 attached hereto.

       

      8.           No course of dealing on the part of Agent or the Holders or their respective officers, nor any failure or delay in the
          exercise of any right by Agent or the Holders, shall operate as a waiver thereof, and any single or partial exercise of any such right shall not preclude any later exercise of any such right except as specially waived herein.  Except as
          specifically waived herein, Agent’s or any Holder’s failure at any time to require strict compliance by Issuer of any provision under the NPA, shall not affect any right of Agent or the Holders under the NPA thereafter to demand strict
          compliance.  Any suspension or waiver of a right must be in writing signed by an officer of Agent or the Holders, as applicable.

       

      9.           The NPA, as amended hereby, shall be and remain in full force and effect in accordance with their respective terms and
          hereby are ratified and confirmed in all respects.  Except as expressly set forth herein, the execution, delivery, and performance of this Amendment shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Agent or
          the Holders under the NPA, as in effect prior to the date hereof.

       

      
        
          


      

      10.        Issuer hereby represents and warrants that (a) the representations and warranties in the NPA, shall be true, accurate, and
          complete in all material respects immediately after giving effect to this Amendment; provided, that such materiality qualifier shall not be applicable to any representations and warranties that already are qualified or modified by
          materiality in the text thereof, which representations and warranties shall be true, accurate and complete immediately after giving effect to this Amendment in all respects subject to such qualification; and provided, further,
          that those representations and warranties expressly referring to a specific date shall be true, accurate and complete in all material respects as of such date, (b) other than the Existing Defaults, no Default or Event of Default shall have
          occurred and be continuing immediately after giving effect to this Amendment, (c) Issuer has the power and authority to execute and deliver this Amendment and to perform its obligations under the NPA, as amended by this Amendment, (d) the
          execution and delivery by Issuer of this Amendment and the performance by Issuer of its obligations under the NPA, as amended by this Amendment, have been duly authorized by Issuer, (e) the execution and delivery by Issuer of this Amendment and
          the performance by Issuer of its obligations under the NPA, as amended by this Amendment, do not and will not contravene (i) any law or regulation binding on or affecting Issuer, (ii) any contractual restriction with a Person binding on Issuer,
          (iii) any order, judgment or decree of any court or other governmental or public body or authority, or subdivision thereof, binding on Issuer, or (iv) the organizational documents of Issuer, (f) the execution and delivery by Issuer of this
          Amendment and the performance by Issuer of its obligations under the NPA, as amended by this Amendment, do not require any order, consent, approval, license, authorization or validation of, or filing, recording or registration with, or exemption
          by any governmental or public body or authority, or subdivision thereof, binding on Issuer, except as already has been obtained or made, and (g) this Amendment has been duly executed and delivered by Issuer and is the binding obligation of
          Issuer, enforceable against Issuer in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, liquidation, moratorium or other similar laws of general application and equitable principles
          relating to or affecting creditors’ rights.

       

      11.         Release by Issuer.

       

      A.           FOR GOOD AND VALUABLE CONSIDERATION, Issuer hereby forever relieves, releases, and discharges Agent,
          the Holders and their respective present or former employees, officers, directors, agents, representatives, attorneys, and each of them, from any and all claims, debts, liabilities, demands, obligations, promises, acts, agreements, costs and
          expenses, actions and causes of action, of every type, kind, nature, description or character whatsoever, whether known or unknown, suspected or unsuspected, absolute or contingent, arising out of or in any manner whatsoever connected with or
          related to facts, circumstances, issues, controversies or claims existing or arising from the beginning of time through and including the date of execution of this Amendment (collectively, the “Released Claims”). 


          Without limiting the foregoing, the Released Claims shall include any and all liabilities or claims arising out of or in any manner whatsoever connected with or related to the Note Documents, the recitals hereto, any instruments, agreements or
          documents executed in connection with any of the foregoing or the origination, negotiation, administration, servicing and/or enforcement of any of the foregoing, in each case existing or arising on or prior to the date of this Amendment.

       

      B.            In furtherance of this release, Issuer expressly acknowledges and waives any and all rights under Section 1542 of
        the California Civil Code (or its equivalent under New York law), which provides as follows:

       

      “A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her
        favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or released party.”

       

      
        
          


      

      C.            By entering into this release, Issuer recognizes that no facts or representations are ever absolutely certain and
        it may hereafter discover facts in addition to or different from those which it presently knows or believes to be true, but that it is the intention of Issuer hereby to fully, finally and forever settle and release all matters, disputes and
        differences, known or unknown, suspected or unsuspected; accordingly, if Issuer should subsequently discover that any fact that it relied upon in entering into this release was untrue, or that any understanding of the facts was incorrect, Issuer
        shall not be entitled to set aside this release by reason thereof, regardless of any claim of mistake of fact or law or any other circumstances whatsoever.  Issuer acknowledges that it is not relying upon and has not relied upon any representation
        or statement made by Agent or the Holders with respect to the facts underlying this release or with regard to any of such party’s rights or asserted rights.

       

      D.            This release may be pleaded as a full and complete defense and/or as a cross-complaint or counterclaim against any
        action, suit, or other proceeding that may be instituted, prosecuted or attempted in breach of this release.  Issuer acknowledges that the release contained herein constitutes a material inducement to Agent and the Holders to enter into this
        Amendment, and that Agent and the Holders would not have done so but for their expectation that such release is valid and enforceable in all events.

       

      E.              Issuer hereby represents and warrants to Agent and the Holders, and Agent and the Holders are
          relying thereon, as follows:

       

      1.     Except as expressly stated in this Amendment, neither Agent or the Holders nor any agent, employee or representative of
        Agent or the Holders has made any statement or representation to Issuer regarding any fact relied upon by Issuer in entering into this Amendment.

       

      2.       Issuer has made such investigation of the facts pertaining to this Amendment and all of the matters appertaining
        thereto, as it deems necessary.

       

      3.      The terms of this Amendment are contractual and not a mere recital.

       

      4.     This Amendment has been carefully read by Issuer, the contents hereof are known and understood by Issuer, and this
        Amendment is signed freely, and without duress, by Issuer.

       

      5.        Issuer hereby represents and warrants that it is the sole and lawful owner of all right, title and interest in and to every claim and
        every other matter which it releases herein, and that it has not heretofore assigned or transferred, or purported to assign or transfer, to any person, firm or entity any claims or other matters herein released.  Issuer shall indemnify, defend and
        hold harmless Agent and Holders from and against all claims based upon or arising in connection with prior assignments or purported assignments or transfers of any claims or matters released herein.

       

      12.         As a condition to the effectiveness of this Amendment, Agent shall have received, in form and substance reasonably
          satisfactory to Agent, the following:

          the date hereof in accordance with the wire instructions attached hereto as Supplement I; and

       

      (i)         such other documents, and completion of such other matters, as Agent or Holder may reasonably deem necessary or
          appropriate.

       

      13.        As conditions subsequent to the effectiveness of this Amendment, Agent shall have received, in form and substance
          reasonably satisfactory to Agent, the following by the respective dates (the failure timely to achieve of any of which shall constitute an immediate and non-curable Event of Default):

      13.3           Evidence of (i) Issuer’s receipt of net proceeds of at least Seven Million Five Hundred Thousand Dollars ($7,500,000.00)

        noteholder from time to time party thereto.  All capitalized terms used herein (which are not otherwise specifically defined herein) shall be used in this Secured Promissory Note (this “Note”) as defined in the NWPSA.

      

      

      This Note is issued in accordance with the provisions of the NWPSA and is entitled to the benefits and security of the NWPSA and the other Note

      Whenever possible each provision of this Note shall be interpreted in such manner as to be effective and valid under applicable law, but in case any
        provision of or obligation under this Note shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other
        jurisdiction, shall not in any way be affected or impaired thereby.
