      Dated: February 23, 2022 (the “Issuance Date”)

    For value received, GSE Systems, Inc., a Delaware corporation (the “Maker” or the “Company”), hereby promises to pay to
      the order of Lind Global Fund II LP, a Delaware limited partnership (together with its successors and representatives, the “Holder”), in accordance with the terms hereinafter provided, the principal amount of
      FIVE MILLION SEVEN HUNDRED FIFTY THOUSAND DOLLARS ($5,750,000.00) (the “Principal Amount”).

    

    

    All payments under or pursuant to this Senior Convertible Promissory Note (this “Note”) shall be made in United States Dollars in
      immediately available funds to the Holder at the address of the Holder set forth in the Purchase Agreement (as hereinafter defined) or at such other place as the Holder may designate from time to time in writing to the Maker or by wire transfer of
      funds to the Holder’s account, instructions for which are attached hereto as Exhibit A. The outstanding principal balance of this Note shall be due and payable on February 23, 2024 (the “Maturity Date”) or at such earlier time as provided herein; provided, that the Holder, in its sole discretion, may at the request of the Maker extend the Maturity Date to any date after the original Maturity Date. 
      In the event that the Maturity Date shall fall on Saturday or Sunday, such Maturity Date shall be the next succeeding Business Day. All calculations made pursuant to this Note shall be rounded down to three decimal places.

    ARTICLE 1

    1.1 Purchase Agreement.  This Note has been executed and delivered pursuant to
      the Securities Purchase Agreement, dated as of February 23, 2022 (as the same may be amended from time to time, the “Purchase Agreement”), by and between the Maker and the Holder. Capitalized terms used and not
      otherwise defined herein shall have the meanings set forth for such terms in the Purchase Agreement.

    1.2 Interest. Other than as set forth in Section 3.6(c), this Note shall
      not bear interest.

    1.3 Principal Installment Payments.     Commencing on the date that is 180 days
      from the Issuance Date, the Maker shall pay to the Holder the Outstanding Principal Amount hereunder in eighteen (18) consecutive monthly installments, on such date and each one (1) month anniversary thereof (each, a “Payment

        Date” and collectively the “Monthly Payments”), an amount equal to Three Hundred Nineteen Thousand Four Hundred Forty Four Dollars ($319,444.00), until the Outstanding Principal Amount has been paid in
      full prior to or on the Maturity Date or, if earlier, upon acceleration, conversion or redemption of this Note in accordance with the terms herein.  The Monthly Payments shall, at the Maker’s option, be made in (i) cash, (ii) Repayment Shares, or
      (iii) a combination of cash and Repayment Shares; provided that the number of Repayment Shares shall be determined by dividing the Principal Amount being paid in shares of Common Stock by the Repayment Share Price; provided, however, that no portion
      of the Principal Amount may be paid in Repayment Shares unless such Repayment Shares (A) may be immediately resold under Rule 144 without restriction on the number of shares to be sold or manner of sale, or (B) are registered for resale under the
      1933 Act and the registration statement is in effect and lawfully usable to effect immediate sales of such Repayment Shares. The Company must provide advance written notice to the Holder of whether it will elect to pay a Monthly Payment in cash,
      Repayment Shares or a combination thereof as follows: (i) with respect to the first Monthly Payment, at least ten (10) Business Days before the Payment Date, and (ii) with respect to each Monthly Payment thereafter, within three (3) Business Days of
      the prior Payment Date; provided, however, that if no such notice is provided within the timeframes set forth above, such Monthly Payments shall be made in Repayment Shares.

    1.4 Prepayment. The Maker may repay all, but not less than all, of the then Outstanding Principal Amount upon delivering a Prepayment Notice. If the Maker elects to prepay this Note pursuant to this Section
        1.4, the Holder shall have the right, upon written notice to the Maker (a “Prepayment Conversion Notice”) within five (5) Business Days of the Holder’s receipt of a Prepayment Notice, to convert up
      to one third (1/3) of the Outstanding Principal Amount (the “Maximum Amount”) at the lesser of the Repayment Share Price or the Conversion Price (each as defined below), in accordance with the provisions of
      Article 3, specifying the Principal Amount (up to the Maximum Amount) that the Holder will convert. Upon delivery of a Prepayment Notice, the Maker irrevocably and unconditionally agrees to, within five (5) Business Days of receiving a Prepayment
      Conversion Notice, and if no Prepayment Conversion Notice is received, within ten (10) Business Days of delivery of a Prepayment Notice: (i) repay the amount of the Outstanding Principal Amount minus the Principal Amount set forth in the Prepayment
      Conversion Notice and (ii) issue the applicable Conversion Shares to the Holder in accordance with Article 3, as applicable.  The foregoing notwithstanding, the Maker may not deliver a Prepayment Notice with respect to any Outstanding Principal
      Amount that is subject to a Conversion Notice delivered by the Holder in accordance with Article 3.

    1.5 Delisting from a Trading Market. If at any time the Common Stock ceases to
      be listed on a Trading Market, (i) the Holder may deliver a demand for payment to the Company and, if such a demand is delivered, the Company shall, within ten (10) Business Days following receipt of the demand for payment from the Holder, pay all of
      the Outstanding Principal Amount or (ii) the Holder may, at its election, after the six-month anniversary of the Issuance Date or earlier if a Registration Statement covering the Conversion Shares has been declared effective, upon notice to the
      Company in accordance with Section 5.1, convert all or a portion of the Outstanding Principal Amount and the Conversion Price shall be adjusted to the lower of (A) the then-current Conversion Price and (A) eighty percent (80%) of the average of the
      three (3) lowest daily VWAPs during the twenty (20) Trading Days prior to delivery by the Holder of its notice of conversion pursuant to this Section 1.5.

    1.6 Payment on Non-Business Days.  Whenever any payment to be made shall be due
      on a day which is not a Business Day, such payment may be due on the next succeeding Business Day.

    1.7 Transfer.  This Note may be transferred or sold, subject to the provisions
      of Section 5.8 of this Note, or pledged, hypothecated or otherwise granted as security by the Holder.

    1.8 Replacement.  Upon receipt of a duly executed and notarized written
      statement from the Holder with respect to the loss, theft or destruction of this Note (or any replacement hereof), or, in the case of a mutilation of this Note, upon surrender and cancellation of such Note, the Maker shall issue a new Note, of like
      tenor and amount, in lieu of such lost, stolen, destroyed or mutilated Note.

    1.9 Use of Proceeds.  The Maker shall use the proceeds of this Note as set forth
      in the Purchase Agreement.

    1.10 Status of Note. Subject to the terms of the Purchase Agreement, the
      obligations of the Maker under this Note shall be senior to all other existing Indebtedness and equity of the Company. Subject to the terms of the Purchase Agreement, upon any Liquidation Event (as hereinafter defined), the Holder will be entitled to
      receive, before any distribution or payment is made upon, or set apart with respect to, any Indebtedness of the Maker or any class of capital stock of the Maker, an amount equal to the Outstanding Principal Amount. For purposes of this Note, “Liquidation Event” means a liquidation pursuant to a filing of a petition for bankruptcy under applicable law or any other insolvency or debtor’s relief, an assignment for the benefit of creditors, or a voluntary
      or involuntary liquidation, dissolution or winding up of the affairs of the Maker.

    1.11 Tax Treatment.  The Maker and the Holder agree that for U.S. federal income
      tax purposes, and applicable state, local and non-U.S. income tax purposes, this Note is not intended to be, and shall not be, treated as indebtedness.  Neither the Maker nor the Holder shall take any contrary position on any tax return, or in any
      audit, claim, investigation, inquiry or proceeding in respect of Taxes, unless otherwise required pursuant to a final determination within the meaning of Section 1313 of the Internal Revenue Code of 1986, as amended (the “Code”), or any analogous provision of applicable state, local or non-U.S. law.

    1.12 Limitations on the Number of Repayment Shares Issuable. Notwithstanding
      anything herein to the contrary, the Company may not issue any Repayment Shares in satisfaction of its obligations hereunder to the extent such Repayment Shares would, after giving effect to such issuance and when added to the number of shares of
      Common Stock issued and issuable under the Transaction Documents, cause the issuance of shares under the Transaction Documents to be in excess of (a) 4,144,544 shares of Common Stock or (b)(i) 19.9% of the number of shares of Common Stock outstanding
      as of the date hereof,  or (ii) 19.9% of the total voting power of the Company's securities outstanding as of the date hereof that are entitled to vote on a matter being voted on by holders of the Common Stock, unless and until the Company obtains
      stockholder approval permitting such issuances in accordance with the Trading Market. For purposes of this Section 1.12, beneficial ownership shall be determined in accordance with Section 13(d) of the Securities Exchange Act of 1934, as amended, and
      the rules and regulations promulgated thereunder. To the extent that the Company is unable issue Repayment Shares as result of the limitation provided in this Section 1.12, the Company shall issue the amount of Repayment Shares possible under the
      foregoing limitation and shall pay to the Holder the cash value of the number of Repayment Shares that the Maker is unable to issue at a price per share equal to the VWAP of the Common Stock on the applicable Payment Date.

                  Notice”), in accordance with Section 5.1 to the Maker. The Holder shall deliver this Note to the Maker at the address designated in the Purchase Agreement at such time that this Note is fully converted. With respect to
                partial conversions of this Note, the Maker shall keep written records of the amount of this Note converted as of the date of such conversion (each, a “Conversion Date”). Any amounts of the
                Outstanding Principal Amount converted hereunder shall be credited to the next scheduled Monthly Payment, or if any amount of the Outstanding Principal Amount converted hereunder exceeds the next scheduled Monthly Payment, future Monthly
                Payments shall be credited, as applicable.

            


    

    
      	
              (b)

            	
              Conversion Price. The “Conversion Price” means $1.94, and shall be subject to adjustment as provided herein.

            


    

    3.2 Delivery of Conversion Shares.  As soon as practicable after the occurrence
      of any event requiring the issuance of Common Stock issuable upon conversion of this Note (“Conversion Shares”), and in any event within one (1) Business Day thereafter (such date, the “Share Delivery Date”), the Maker shall, at its expense, cause to be issued in the name of and delivered to the Holder, or as the Holder may direct, a certificate or certificates evidencing the number of fully paid
      and nonassessable Common Stock to which the Holder shall be entitled, in such denominations as may be requested by the Holder, which certificate or certificates shall be free of restrictive and trading legends, except for any such legends as may be
      required under the Securities Act.  In lieu of delivering physical certificates for the shares of Common Stock issuable upon the occurrence of any event requiring the issuance of Conversion Shares in accordance with this Note, provided the Company’s
      transfer agent is participating in the Depository Trust Company (“DTC”) Fast Automated Securities Transfer program or a similar program, upon request of the Holder, the Company shall cause its transfer agent to
      electronically transmit such Conversion Shares so issuable to the Holder (or its designee), by crediting the account of the Holder’s (or such designee’s) broker with DTC through its Deposit and Withdrawal At Custodian (“DWAC”) system (provided that the same time periods herein as for stock certificates shall apply) as instructed by the Holder (or its designee); provided, that such issuance shall only be made through DTC’s DWAC system if such
      Conversion Shares will be issued free of restrictive legends.

    3.3  Ownership Cap. Notwithstanding anything to the contrary contained herein,
      the Holder shall not be entitled to receive shares representing Equity Interests upon conversion of this Note to the extent (but only to the extent) that such exercise or receipt would cause the Holder Group (as defined below) to become, directly or
      indirectly, a “beneficial owner” (within the meaning of Section 13(d) of the 1934 Act and the rules and regulations promulgated thereunder) of a number of Equity Interests of a class that is registered under the 1934 Act which exceeds the Maximum
      Percentage (as defined in the Purchase Agreement) of the Equity Interests of such class that are outstanding at such time.  Any purported delivery of Equity Interests in connection with the conversion of this Note prior to the termination of this
      restriction in accordance herewith shall be void and have no effect to the extent (but only to the extent) that such delivery would result in the Holder Group becoming the beneficial owner of more than the Maximum Percentage of the Equity Interests
      of a class that is registered under the 1934 Act that is outstanding at such time. If any delivery of Equity Interests owed to the Holder following conversion of this Note is not made, in whole or in part, as a result of this limitation, the
      Company’s obligation to make such delivery shall not be extinguished and the Company shall deliver such Equity Interests as promptly as practicable after the Holder gives notice to the Company that such delivery would not result in such limitation
      being triggered or upon termination of the restriction in accordance with the terms hereof.  To the extent limitations contained in this Section 3.3 apply, the determination of whether this Note is convertible and of which portion of this
      Note is convertible shall be the sole responsibility and in the sole determination of the Holder, and the submission of a notice of conversion shall be deemed to constitute the Holder’s determination that the issuance of the full number of Conversion
      Shares requested in the notice of conversion is permitted hereunder, and the Company shall not have any obligation to verify or confirm the accuracy of such determination.  For purposes of this Section 3.2, (i) the term “Maximum Percentage” shall mean 4.99%; provided, that if at any time after the date hereof the Holder Group beneficially owns in excess of 4.99% of any class of Equity Interests in the Company that is registered
      under the 1934 Act, then the Maximum Percentage shall automatically increase to 9.99% so long as the Holder Group owns in excess of 4.99% of such class of Equity Interests (and shall, for the avoidance of doubt, automatically decrease to 4.99% upon
      the Holder Group ceasing to own in excess of 4.99% of such class of Equity Interests); and (ii) the term “Holder Group” shall mean the Holder plus any other Person with which the Holder is considered to be part
      of a group under Section 13 of the 1934 Act or with which the Holder otherwise files reports under Sections 13 and/or 16 of the 1934 Act.  In determining the number of Equity Interests of a particular class outstanding at any point in time, the
      Holder may rely on the number of outstanding Equity Interests of such class as reflected in (x) the Company’s most recent Annual Report on Form 20-F filed with the Securities and Exchange Commission, as the case may be, (y) a more recent public
      announcement by the Company or (z) a more recent notice by the Company or its transfer agent to the Holder setting forth the number of Equity Interests of such class then outstanding.  For any reason at any time, upon written or oral request of the
      Holder, the Company shall, within one (1) Business Day of such request, confirm orally and in writing to the Holder the number of Equity Interests of any class then outstanding. The provisions of this Section 3.3 shall be construed, corrected
      and implemented in a manner so as to effectuate the intended beneficial ownership limitation herein contained.

    3.4 Adjustment of Conversion Price.

    
      	
              (a)

            	
              Until the Note has been paid in full or converted in full, the Conversion Price shall be subject to adjustment from time to time as follows (but shall not be
                increased, other than pursuant to Section 3.4(a)(i) hereof):

            


    

    (i) Adjustments for Stock Splits and Combinations.  If the Maker shall at any
      time or from time to time after the Closing Date (but whether before or after the Issuance Date) effect a split or other subdivision of the outstanding Common Stock, the applicable Conversion Price in effect immediately prior to the stock split shall
      be proportionately decreased. If the Maker shall at any time or from time to time after the Closing Date (but whether before or after the Issuance Date), combine the outstanding Common Stock, the applicable Conversion Price in effect immediately
      prior to the combination shall be proportionately increased. Any adjustments under this Section 3.4(a)(i) shall be effective at the close of business on the date the stock split or combination occurs.

    (ii) Adjustments for Certain Dividends and Distributions.  If the Maker shall
      at any time or from time to time after the Closing Date (but whether before or after the Issuance Date) make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable
      in Common Stock, then, and in each event, the applicable Conversion Price in effect immediately prior to such event shall be decreased as of the time of such issuance or, in the event such record date shall have been fixed, as of the close of
      business on such record date, by multiplying the applicable Conversion Price then in effect by a fraction:

    (1) the numerator of which shall be the total number of shares of Common Stock issued
      and outstanding immediately prior to the time of such issuance or the close of business on such record date; and

    (2) the denominator of which shall be the total number of shares of Common Stock
      issued and outstanding immediately prior to the time of such issuance or the close of business on such record date plus the number of shares of Common Stock issuable in payment of such dividend or distribution.

    (iii) Adjustment for Other Dividends and Distributions.  If the Maker shall at
      any time or from time to time after the Closing Date (but whether before or after the Issuance Date) make or issue or set a record date for the determination of holders of Common Stock entitled to receive a dividend or other distribution payable in
      other than Common Stock, then, and in each event, an appropriate revision to the applicable Conversion Price shall be made and provision shall be made (by adjustments of the Conversion Price or otherwise) so that the Holder of this Note shall receive
      upon conversions thereof, in addition to the number of shares of Common Stock receivable thereon, the number of securities of the Maker or other issuer (as applicable) or cash or other property that it would have received had this Note been converted
      into shares of Common Stock in full (without regard to any conversion limitations herein) on the date of such event and had thereafter, during the period from the date of such event to and including the Conversion Date, retained such securities
      (together with any distributions payable thereon during such period) or assets, giving application to all adjustments called for during such period under this Section 3.4(a)(iii) with respect to the rights of the holders of this Note; provided, however, that if such record date shall have been fixed and such dividend is not fully paid or if such distribution is not fully made on the date fixed therefor, the Conversion Price shall be adjusted
      pursuant to this paragraph as of the time of actual payment of such dividends or distributions.

    (iv) Adjustments for Reclassification, Exchange or Substitution.  If the shares
      of Common Stock at any time or from time to time after the Closing Date (but whether before or after the Issuance Date) shall be changed to the same or different number of shares or other securities of any class or classes of stock or other property,
      whether by reclassification, exchange, substitution or otherwise (other than by way of a stock split or combination of shares or stock dividends provided for in Sections 3.4(a)(i), (ii) and (iii) hereof, or a reorganization, merger,
      consolidation, or sale of assets provided for in Section 3.4(a)(vii) hereof), then, and in each event, an appropriate revision to the Conversion Price shall be made and provisions shall be made (by adjustments of the Conversion Price or
      otherwise) so that the Holder shall have the right thereafter to convert this Note into the kind and amount of shares of stock or other securities or other property receivable upon reclassification, exchange, substitution or other change, by holders
      of the number of shares of Common Stock into which such Note might have been converted immediately prior to such reclassification, exchange, substitution or other change, all subject to further adjustment as provided herein.

    (v) Adjustments for Issuance of Additional Shares of Common Stock. In the event
      the Maker shall, at any time or from time to time after the Closing Date (but whether before or after the Issuance Date), issue or sell any additional Common Stock (“Additional Common Stock”), other than (A) as provided in this Note (including
      the foregoing subsections (i) through (iv) of this Section 3.4(a)), (B) pursuant to any Equity Plan (including pursuant to Common Stock Equivalents granted or issued under any Equity Plan), (C) pursuant to Common Stock Equivalents (as defined
      below) granted or issued prior to the Closing Date, (D) Exempted Securities, or (E) pursuant to the terms of this Note, at an effective price per share that is less than the Conversion
      Price then in effect or without consideration, then the Conversion Price upon each such issuance shall be reduced to a price equal to the consideration per share paid for such Additional Common Stock. For purposes of clarification, the amount of
      consideration received for such Additional Common Stock shall not include the value of any additional securities or other rights received in connection with such issuance of Additional Common Stock (i.e. warrants, rights of first refusal or other
      similar rights).

    (vi) Issuance, Amendment or Adjustment of Common Stock Equivalents.  Except for
      Exempted Securities or the Warrant, if (x) the Maker, at any time after the Closing Date (but whether before or after the Issuance Date), shall issue any securities convertible into or exercisable or exchangeable for, directly or indirectly, Common
      Stock (“Convertible Securities”), or any rights or warrants or options to purchase any such Common Stock or Convertible Securities, other than Common Stock Equivalents granted or issued under any Equity Plan (collectively with the Convertible
      Securities, the “Common Stock Equivalents”) and the price per share for which Common Stock may be issuable pursuant to any such Common Stock Equivalent shall be less than the
      applicable Conversion Price then in effect, or (y) the price per share for which Common Stock may be issuable under any Common Stock Equivalents is amended or adjusted, pursuant to the terms of such Common Stock Equivalents or otherwise, and such
      price as so amended or adjusted shall be less than the applicable Conversion Price in effect at the time of such amendment or adjustment, then, in each such case (x) or (y), the applicable Conversion Price upon each such issuance or amendment or
      adjustment shall be adjusted as provided in subsection (vi) of this Section 3.4(a) as if the maximum number of shares of Common Stock issuable upon conversion, exercise or exchange of such Common Stock Equivalents had been issued on the date
      of such issuance or amendment or adjustment.

    (vii) Consideration for Stock.  In case any shares of Common Stock or any
      Common Stock Equivalents shall be issued or sold:

    (1) in connection with any merger or consolidation in which the Maker is the surviving
      corporation (other than any consolidation or merger in which the previously outstanding Common Stock of the Maker shall be changed to or exchanged for the stock or other securities of another corporation), the amount of consideration therefor shall
      be deemed to be the fair value, as determined reasonably and in good faith by the Board of Directors of the Maker and approved by the Holder, of such portion of the assets and business of the nonsurviving corporation as such Board of Directors may
      determine to be attributable to such shares of Common Stock, Convertible Securities, rights or warrants or options, as the case may be; or

    
      5

      
        


    

    (2) in the event of any consolidation or merger of the Maker in which the Maker is not
      the surviving corporation or in which the previously outstanding Common Stock of the Maker shall be changed into or exchanged for the stock or other securities of another corporation or other property, or in the event of any sale of all or
      substantially all of the assets of the Maker for stock or other securities or other property of any corporation, the Maker shall be deemed to have issued shares of Common Stock, at a price per share equal to the valuation of the Maker’s Common Stock
      based on the actual exchange ratio on which the transaction was predicated, as applicable, and the fair market value on the date of such transaction of all such stock or securities or other property of the other corporation. If any such calculation
      results in adjustment of the applicable Conversion Price, or the number of shares of Common Stock issuable upon conversion of the Note, the determination of the applicable Conversion Price or the number of shares of Common Stock issuable upon
      conversion of the Note immediately prior to such merger, consolidation or sale, shall be made after giving effect to such adjustment of the number of shares of Common Stock issuable upon conversion of the Note. In the event shares of Common Stock are
      issued with other shares or securities or other assets of the Maker for consideration which covers both, the consideration computed as provided in this Section 3.4(a)(vii) shall be allocated among such securities and assets as determined in
      good faith by the Board of Directors of the Maker, and approved by the Holder.

    (viii) Record Date.  In case the Maker shall take record of the holders of its
      Common Stock for the purpose of entitling them to subscribe for or purchase shares of Common Stock or Convertible Securities, then the date of the issue or sale of the shares of Common Stock shall be deemed to be such record date.

    
      	
              (b)

            	
              No Impairment.  The Maker shall not, by amendment of its Certificate of Incorporation or through any reorganization, transfer of assets, consolidation, merger,
                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 to be observed or performed hereunder by the Maker, but will at all times in good faith assist
                in the carrying out of all the provisions of this Section 3.4 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the Holder against impairment. In the event the
                Holder shall elect to convert this Note as provided herein, the Maker cannot refuse conversion based on any claim that the Holder or anyone associated or affiliated with the Holder has been engaged in any violation of law, violation of an
                agreement to which the Holder is a party or for any reason whatsoever, unless, an injunction from a court, or notice, restraining and or adjoining conversion of this Note shall have issued.

            


    

    
      	
              (c)

            	
              Certificates as to Adjustments.  Upon occurrence of each adjustment or readjustment of the Conversion Price or number of shares of Common Stock issuable upon
                conversion of this Note pursuant to this Section 3.4, the Maker at its expense shall promptly compute such adjustment or readjustment in accordance with the terms hereof and furnish to the Holder a certificate setting forth such
                adjustment and readjustment, showing in detail the facts upon which such adjustment or readjustment is based. The Maker shall, upon written request of the Holder, at any time, furnish or cause to be furnished to the Holder a like
                certificate setting forth such adjustments and readjustments, the applicable Conversion Price in effect at the time, and the number of shares of Common Stock and the amount, if any, of other securities or property which at the time would be
                received upon the conversion of this Note. Notwithstanding the foregoing, the Maker shall not be obligated to deliver a certificate unless such certificate would reflect an increase or decrease of at least one percent (1%) of such adjusted
                amount.

            


    

    
      	
              (d)

            	
              Issue Taxes. The Maker shall pay any and all issue and other taxes, excluding federal, state or local income taxes, that may be payable in respect of any issue
                or delivery of shares of Common Stock on conversion of this Note pursuant thereto; provided, however, that the Maker shall not be obligated to pay any transfer taxes resulting from any transfer
                requested by the Holder in connection with any such conversion.

            


    

    
      	
              (e)

            	
              Fractional Shares. No fractional shares of Common Stock shall be issued upon conversion of this Note. In lieu of any fractional shares to which the Holder
                would otherwise be entitled, the Maker shall pay cash equal such fractional shares multiplied by the Conversion Price then in effect.

            


    

    
      	
              (f)

            	
              Reservation of Shares of Common Stock. The Maker shall at all times while this Note shall be outstanding, reserve and keep available out of its authorized but
                unissued Common Stock, such number of shares of Common Stock as shall from time to time be sufficient to effect the conversion of this Note (disregarding for this purpose any and all limitations of any kind on such conversion). The Maker
                shall, from time to time, use all commercially reasonable efforts to increase the authorized number of shares of Common Stock or take other effective action if at any time the unissued number of authorized shares shall not be sufficient to
                satisfy the Maker’s obligations under this Section 3.4(f).

            


    

    
      	
              (g)

            	
              Regulatory Compliance.  If any shares of Common Stock to be reserved for the purpose of conversion of this Note require registration or listing with or
                approval of any governmental authority, stock exchange or other regulatory body under any federal or state law or regulation or otherwise before such shares may be validly issued or delivered upon conversion, the Maker shall, at its sole
                cost and expense, in good faith and as expeditiously as possible, secure such registration, listing or approval, as the case may be.

            


    

    
      	
              (h)

            	
              Effect of Events Prior to the Issuance Date.  If the Issuance Date of this Note is after the Closing Date, then, if the Conversion Price or any other right of
                the Holder of this Note would have been adjusted or modified by operation of any provision of this Note had this Note been issued on the Closing Date, such adjustment or modification shall be deemed to apply to this Note as of the Issuance
                Date as if this Note had been issued on the Closing Date.

            


    

    3.5 Prepayment Following a Change of Control.

    
      	
              (a)

            	
              Mechanics of Prepayment at Option of Holder in Connection with a Change of Control.  No sooner than fifteen (15) days prior to entry into an agreement for a
                Change of Control nor later than ten (10) days prior to the consummation of a Change of Control, but not prior to the public announcement of such Change of Control, the Maker shall deliver written notice (“Notice

                  of Change of Control”) to the Holder. At any time after receipt of a Notice of Change of Control (or, in the event a Notice of Change of Control is not delivered at least ten (10) days prior to a Change of Control, at any time
                within ten (10) days prior to a Change of Control), the Holder may require the Maker to prepay, effective immediately prior to the consummation of such Change of Control, an amount equal to the Outstanding Principal Amount (the “COC Repayment Price”), by delivering written notice thereof (“Notice of Prepayment at Option of Holder Upon Change of Control”) to the Maker.

            


    

    
      	
              (b)

            	
              Payment of COC Repayment Price.  Upon the Maker’s receipt of a Notice(s) of Prepayment at Option of Holder Upon Change of Control from the Holder, the Maker
                shall deliver the COC Repayment Price to the Holder immediately prior to the consummation of the Change of Control; provided that the Holder’s original Note shall have been so delivered to the Maker.

    3.6 Inability to Fully Convert.

    
      	
              (a)

            	
              Holder’s Option if Maker Cannot Fully Convert.  If, upon the Maker’s receipt of a Conversion Notice or as otherwise required under this Note,
                including with respect to repayment of principal in Common Stock as permitted under this Note, the Maker cannot issue Common Stock for any reason, including, without limitation, because the Maker (x) does not have a sufficient number of
                shares of Common Stock authorized and available or (y) is otherwise prohibited by applicable law or by the rules or regulations of any stock exchange, interdealer quotation system or other self-regulatory organization with jurisdiction over
                the Maker or any of its securities from issuing all of the shares of Common Stock which are to be issued to the Holder pursuant to this Note, then the Maker shall issue as many shares of Common Stock as it is able to issue and, with respect
                to the unconverted portion of this Note or with respect to any shares of Common Stock not timely issued in accordance with this Note, the Holder, solely at Holder’s option, can elect to:

            


    

    (i) require the Maker to prepay that portion of this Note for which the Maker is
      unable to issue Common Stock or for which shares of Common Stock were not timely issued (the “Mandatory Prepayment”) at a price equal to the number of shares of Common Stock that the Maker is unable to issue
      multiplied by the VWAP on the date of the Conversion Notice (the “Mandatory Prepayment Price”);

    (ii) void its Conversion Notice and retain or have returned, as the case may be, this
      Note that was to be converted pursuant to the Conversion Notice (provided that the Holder’s voiding its Conversion Notice shall not affect the Maker’s obligations to make any payments which have accrued prior to the date of such notice); or

    (iii) defer issuance of the applicable Conversion Shares until such time as the Maker
      can legally issue such shares; provided, that the Principal Amount underlying such Conversion Shares shall remain outstanding until the delivery of such Conversion Shares; provided, further, that if the Holder elects to defer the issuance of the
      Conversion Shares, it may exercise its rights under either clause (i) or (ii) above at any time prior to the issuance of the Conversion Shares upon two (2) Business Days’ notice to the Maker.

    
      	
              (b)

            	
              Mechanics of Fulfilling Holder’s Election.  The Maker shall immediately send to the Holder, upon receipt of a Conversion Notice from the Holder, which cannot
                be fully satisfied as described in Section 3.6(a) above, a notice of the Maker’s inability to fully satisfy the Conversion Notice (the “Inability to Fully Convert Notice”).  Such Inability to
                Fully Convert Notice shall indicate (i) the reason why the Maker is unable to fully satisfy the Holder’s Conversion Notice; and (ii) the amount of this Note which cannot be converted. The Holder shall notify the Maker of its election
                pursuant to Section 3.6(a) above by delivering written notice to the Maker (“Notice in Response to Inability to Convert”).

            


    

    
      	
              (c)

            	
              Payment of Mandatory Prepayment Price.  If the Holder shall elect to have its Note prepaid pursuant to Section 3.6(a)(i) above, the Maker shall pay the
                Mandatory Prepayment Price to the Holder within five (5) Business Days of the Maker’s receipt of the Holder’s Notice in Response to Inability to Convert; provided that prior to the Maker’s receipt of the Holder’s Notice in Response to
                Inability to Convert the Maker has not delivered a notice to the Holder stating, to the satisfaction of the Holder, that the event or condition resulting in the Mandatory Prepayment has been cured and all Conversion Shares issuable to the
                Holder can and will be delivered to the Holder in accordance with the terms of this Note. If the Maker shall fail to pay the applicable Mandatory Prepayment Price to the Holder on the date that is one (1) Business Day following the Maker’s
                receipt of the Holder’s Notice in Response to Inability to Convert, in addition to any remedy the Holder may have under this Note and the Purchase Agreement, such unpaid amount shall bear interest at the rate of two percent (2%) per month
                (prorated for partial months) until paid in full. Until the full Mandatory Prepayment Price is paid in full to the Holder, the Holder may (i) void the Mandatory Prepayment with respect to that portion of the Note for which the full
                Mandatory Prepayment Price has not been paid and (ii) receive back such Note.

            


    

    
      	
              (d)

            	
              No Rights as Stockholder.  Nothing contained in this Note shall be construed as conferring upon the Holder, prior to the conversion of this Note, the right to
                vote or to receive dividends or to consent or to receive notice as a stockholder in respect of any meeting of stockholders for the election of directors of the Maker or of any other matter, or any other rights as a stockholder of the Maker.

            


    

    3.7 Compensation for Buy-In on Failure to Timely Deliver Conversion Shares.  In
      addition to any other rights available to the Holder, if the Company fails to cause its transfer agent to transmit to the Holder Conversion Shares or any other shares pursuant to a conversion on or before the Share Delivery Date, and if after such
      date the Holder is required by its broker to purchase (in an open market transaction or otherwise) or the Holder’s brokerage firm otherwise purchases, shares of Common Stock to deliver in satisfaction of a sale by the Holder of the Conversion Shares
      which the Holder anticipated receiving upon such conversion (a “Buy-In”), then the Company shall (a) pay in cash to the Holder the amount, if any, by which (x) the Holder’s total purchase price (including
      brokerage commissions, if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (1) the number of Conversion Shares that the Company was required to deliver to the Holder in connection with the conversion at
      issue times (2) the price at which the sell order giving rise to such purchase obligation was executed, and (b) at the option of the Holder, either reinstate the portion of the Note and equivalent number of Conversion Shares for which such conversion
      was not honored (in which case such conversion shall be deemed rescinded) or deliver to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its conversion and delivery obligations
      hereunder. For example, if the Holder purchases shares of Common Stock having a total purchase price of $11,000 to cover a Buy-In with respect to an attempted conversion of shares of Common Stock with an aggregate sale price giving rise to such
      purchase obligation of $10,000, under clause (a) of the immediately preceding sentence the Company shall be required to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect
      of the Buy-In and evidence of the amount of such loss. Nothing herein shall limit a Holder’s right to pursue a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver shares of Common Stock upon
      conversion of the Note as required pursuant to the terms hereof.

                other rights to use property owned or possessed by it and reasonably deemed to be necessary to the conduct of its business.

                issuing such debt or Equity Interests, the Company will direct (i) one hundred percent of the proceeds from the issuance of such debt to repay this Note, or (ii) twenty percent (20%) of the proceeds from the issuance of such Equity

      part of this Note and shall not be deemed to limit or affect any of the provisions hereof.  The language used in this Note will be deemed to be the language chosen by the parties to express their mutual intent, and no rules of strict construction
      will be applied against any party. This Note shall be construed as if drafted jointly by the parties, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Note.

      contained herein shall be deemed a waiver of compliance with the provisions giving rise to such remedy and nothing herein shall limit the Holder’s right to pursue actual damages for any failure by the Maker to comply with the terms of this Note.

      limited to an injunction restraining any such breach or threatened breach, without the necessity of showing economic loss and without any bond or other security being required.

      except in a written instrument signed by the Company and the Holder. No waiver of any default with respect to any provision, condition or requirement of this Note shall be deemed to be a continuing waiver in the future or a waiver of any subsequent
      default or a waiver of any other provision, condition or requirement hereof, nor shall any delay or omission of either party to exercise any right hereunder in any manner impair the exercise of any such right.
