        Expiration Date by delivery to the Company (or such other office or agency of the Company as it may designate by notice in writing to the registered Holder at the address of the Holder appearing on the books of the Company) of a duly executed
        facsimile or electronic copy of the Notice of Exercise in the form annexed hereto (the “Notice of Exercise”) and within two (2) Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received

        hereunder shall have the effect of lowering the outstanding number of Warrant Shares purchasable hereunder in an amount equal to the applicable number of Warrant Shares purchased.  The Holder and the Company shall maintain records showing the
        number of Warrant Shares purchased and the date of such purchases. The Holder and any assignee, by acceptance of this Warrant, acknowledge and agree that, by reason of the provisions of this paragraph, following
          the purchase of a portion of the Warrant Shares hereunder, the number of Warrant Shares available for purchase hereunder at any given time may be less than the amount stated on the face hereof.

       

      
        

        4

        
          


        

      

      In the event that immediately prior to the close of business on the Expiration Date, the Closing Bid Price of one share of Common Stock is greater than the then applicable
        Exercise Price, this Warrant shall be deemed to be automatically exercised as a “cashless exercise” pursuant to Section 2(c) below, and the Company shall deliver the applicable number of shares of Common Stock to the Holder pursuant to the
        provisions of Section 2(d) below.

       

      b)           Exercise Price.  The exercise price per share of the Common Stock under this Warrant shall be $5.22, subject to adjustment hereunder (the “Exercise Price”).

       

      c)          Cashless Exercise.  This Warrant may be exercised, in whole or in part, at any time by means of a “cashless exercise” in which the Holder shall be entitled to
        receive a number of Warrant Shares equal to the quotient obtained by dividing [(A-B) (X)] by (A) (a “Cashless Exercise”), where:

       

      (A) = the VWAP on the Trading Day immediately preceding the date on which Holder elects to exercise this Warrant by means of a “cashless exercise,” as set forth in the
        applicable Notice of Exercise;

      

      

      (B) = the Exercise Price of this Warrant, as adjusted hereunder; and

      

      

      (X) =  the number of Warrant Shares that would be issuable upon exercise of this Warrant in accordance with the terms of this Warrant if such exercise were by means of a cash
        exercise rather than a cashless exercise or, if only a portion of this Warrant is being exercised, the portion of this Warrant being cancelled.

            d)           Mechanics of Exercise.

          

        

      

       

      i.          Delivery of Warrant Shares Upon Exercise.  Warrant Shares purchased hereunder shall be transmitted by the Transfer Agent to the Holder by crediting the
        account of the Holder’s prime broker with The Depository Trust Company through its Deposit or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and the Warrant Shares are eligible for resale by the
        Holder without volume or manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the Holder in the Notice of Exercise by the date that is two (2) Trading Days after the delivery to the
        Company, by 11 a.m. (local time in New York City, New York) on a Trading Day, of the Notice of Exercise and payment of the aggregate Exercise Price as set forth above (including by Cashless Exercise) (such date, the “Warrant Share Delivery Date”). 

        The Warrant Shares shall be deemed to have been issued, and the Holder or any other person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares for all purposes, as of the date this Warrant has
        been exercised, with payment to the Company of the Exercise Price (or by Cashless Exercise) and all taxes required to be paid by the Holder, if any, pursuant to Section 2(d)(v) prior to the issuance of such Warrant Shares, having been
        paid.  If the Company fails for any reason to deliver to the Holder the Warrant Shares subject to a Notice of Exercise by the Warrant Share Delivery Date, other than a failure to deliver caused by the Holder’s failure to pay the applicable Exercise
        Price for such Warrant Shares or to timely take such actions as are necessary to post such Warrant Shares in DWAC, the Company shall pay to the Holder, in cash, as liquidated damages and not as a penalty, for each $1,000 of Warrant Shares subject
        to such exercise (based on the VWAP of the Common Stock on the date of the applicable Notice of Exercise), an amount equal to the Exercise Price per Trading Day for each Trading Day after such Warrant Share Delivery Date until such Warrant Shares
        are delivered or Holder rescinds such exercise.

       

      ii.          Delivery of New Warrants Upon Exercise.  If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder and upon surrender
        of this Warrant certificate, at the time of delivery of the Warrant Shares, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Shares called for by this Warrant, which new Warrant shall in
        all other respects be identical with this Warrant.

       

      iii.         Rescission Rights.  If the Company fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to Section 2(d)(i) by the
        third (3rd) Trading Day following the Warrant Share Delivery Date, other than a failure to deliver caused by the Holder’s failure to pay the applicable Exercise Price
        for such Warrant Shares or to timely take such actions as are necessary to post such Warrant Shares in DWAC, then the Holder will have the right to rescind such exercise.

       

      

      
        

        6

        
          


        

      

      iv.         Compensation for Buy-In on Failure to Timely Deliver Warrant Shares Upon Exercise.  In addition to any other rights available to the Holder, if the Company
        fails to cause the Transfer Agent to transmit to the Holder the Warrant Shares pursuant to an exercise on or before the second (2nd) Trading Day following the Warrant
        Share Delivery Date and such failure is not caused by any act or omission of the Holder, and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise) shares of Common Stock to deliver in
        satisfaction of a sale by the Holder of the Warrant Shares which the Holder anticipated receiving upon such exercise (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 (provided, Holder exercises reasonable efforts to minimize the amount of such purchase price) exceeds (y) the amount obtained by multiplying (1)
        the number of Warrant Shares that the Company was required to deliver to the Holder in connection with the exercise at issue by (2) the actual sale 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 Warrant and equivalent number of Warrant Shares for which such exercise was not honored (in which case such exercise 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 exercise and delivery obligations hereunder.  For example, if the Holder purchases Common Stock having a total purchase price of $11,000 to cover a Buy-In with
        respect to an attempted exercise to acquire Warrant Shares 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, upon request of the Company, evidence of the amount of such loss.  Nothing herein shall limit a Holder’s right to
        pursue any other remedies available to it hereunder, at law or in equity, including, without limitation, a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver Warrant Shares upon exercise
        of the Warrant as required pursuant to the terms hereof.

       

      v.          No Fractional Shares or Scrip.  No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant.  As to any
        fraction of a share which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election, either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by
        the Exercise Price or round up to the next whole share.

       

      vi.          Charges, Taxes and Expenses.  Issuance of Warrant Shares shall be made without charge to the Holder for any issue or transfer tax or other incidental expense
        in respect of the issuance of Warrant Shares, all of which taxes and expenses shall be paid by the Company, and such Warrant Shares shall be issued in the name of the Holder or in such name or names as may be directed by the Holder; provided,
        however, that in the event that Warrant Shares are to be issued in a name other than the name of the Holder, this Warrant when surrendered for exercise shall be accompanied by a completed Assignment Form in the form attached hereto duly
        executed by the Holder and the Company may require, as a condition thereto, the payment of a sum sufficient to reimburse it for any transfer tax incidental thereto.  The Company shall pay all Transfer Agent fees required for same-day processing of
        any Notice of Exercise and all fees to the Depository Trust Company (or another established clearing corporation performing similar functions) required for same-day electronic delivery of the Warrant Shares.

       

      
        

        7

        
          


        

      

      vii.         Closing of Books.  The Company will not close its stockholder books or records in any manner which prevents the timely exercise of this Warrant, pursuant to
        the terms hereof.

       

      e)          Holder’s Exercise Limitations. The Company shall not effect any exercise of this Warrant, and a Holder shall not have the right to exercise any portion of this
        Warrant, pursuant to this Section 2 or otherwise, to the extent that after giving effect to such issuance after exercise as set forth on the applicable Notice of Exercise, 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), would beneficially own in excess of the Beneficial Ownership Limitation (as defined below).  For purposes of the foregoing sentence, the number of shares of
        Common Stock beneficially owned by the Holder and its Affiliates shall include the number of shares of Common Stock issuable upon exercise of this Warrant with respect to which such determination is being made, but shall exclude the number of
        shares of Common Stock which would be issuable upon (i) exercise of the remaining, nonexercised portion of this Warrant beneficially owned by the Holder or any of its Affiliates, and (ii) exercise or conversion of the unexercised or nonconverted
        portion of any other securities of the Company (including, without limitation, any other Common Stock Equivalents) subject to a limitation on conversion or exercise analogous to the limitation contained herein beneficially owned by the Holder or
        any of its Affiliates.  Except as set forth in the preceding sentence, for purposes of this Section 2(e), beneficial ownership shall be calculated in accordance with Section 13(d) of the Exchange Act and the rules and regulations
        promulgated thereunder, it being acknowledged by the Holder that the Company is not representing to the Holder that such calculation is in compliance with Section 13(d) of the Exchange Act and the Holder is solely responsible for any schedules
        required to be filed in accordance therewith.  To the extent that the limitation contained in this Section 2(e) applies, the determination of whether this Warrant is exercisable (in relation to other securities owned by the Holder together
        with any Affiliates) and of which portion of this Warrant is exercisable shall be in the sole discretion of the Holder, and the submission of a Notice of Exercise shall be deemed to be the Holder’s determination of whether this Warrant is
        exercisable (in relation to other securities owned by the Holder together with any Affiliates) and of which portion of this Warrant is exercisable, in each case subject to the Beneficial Ownership Limitation, and the Company shall have no
        obligation to verify or confirm the accuracy of such determination.  In addition, a determination as to any group status as contemplated above shall be determined in accordance with Section 13(d) of the Exchange Act and the rules and regulations
        promulgated thereunder.  For purposes of this Section 2(e), in determining the number of outstanding shares of Common Stock, a Holder may rely on the number of outstanding shares of Common Stock as reflected in (A) the Company’s most recent
        periodic or annual report filed with the Commission, as the case may be, (B) a more recent public announcement by the Company, or (C) a more recent written notice from the Company or the Transfer Agent setting forth the number of shares of Common
        Stock outstanding.  Upon the written request of a Holder, the Company shall within three (3) Trading Days confirm orally and in writing to the Holder the number of shares of Common Stock then outstanding.  In any case, the number of outstanding
        shares of Common Stock shall be determined after giving effect to the conversion or exercise of securities of the Company, including this Warrant, by the Holder or its Affiliates since the date as of which such number of outstanding shares of
        Common Stock was reported.  The “Beneficial Ownership Limitation” shall be 9.99% of the number of shares of the Common Stock outstanding immediately after giving effect to the applicable issuance of shares of Common Stock issuable upon
        exercise of this Warrant.  The provisions of this paragraph shall be construed and implemented in a manner otherwise than in strict conformity with the terms of this Section 2(e) to correct this paragraph (or any portion hereof) which may
        be defective or inconsistent with the intended Beneficial Ownership Limitation herein contained or to make changes or supplements necessary or desirable to properly give effect to such limitation. The limitations contained in this paragraph shall
        apply to a successor holder of this Warrant.

       

      
        

        8

        
          


        

      

      f)            No Violation. The Company shall reasonably cooperate with the Holder, and take all such
          actions as may be reasonably necessary, in order to ensure that all such Warrant Shares are issued without violation by the Company of any applicable law or governmental regulation or of any requirements of any Trading Market on which Common
          Stock is listed at the time of exercise of this Warrant (except for official notice of issuance which shall be immediately delivered by the Company upon each such issuance).

       

      Section 3.             Certain Adjustments. In order to prevent dilution of the purchase rights granted under this Warrant Certificate, the Exercise Price and the number of Warrant
        Shares issuable upon exercise of this Warrant Certificate shall be subject to adjustment from time to time as provided in this Section 3.

       

      a)           Adjustment to Exercise Price Upon Issuance of Common Stock.  Subject to Section 3(c), if the Company shall, at any time after the date hereof (the “Issue

          Date”) and prior to the first anniversary of the Issue Date, issue or sell any shares of Common Stock (other than in an Excluded Issuance or any event described in Section 3(d) or (e)), whether directly or indirectly by way of Options
        or Convertible Securities, without consideration or for consideration per share less than the Exercise Price in effect immediately prior to such issuance or sale, then immediately upon such issuance or sale, the Exercise Price in effect immediately
        prior to such issuance or sale shall be reduced (and in no event increased) to an Exercise Price equal to the quotient obtained by dividing:

       

      i.            the sum of (A) the product obtained by multiplying the Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance or sale) by
        the Exercise Price then in effect plus (B) the aggregate consideration, if any, received by the Company upon such issuance or sale (or deemed issuance or sale); by

       

      
        

        9

        
          


        

      

      ii.           the sum of (A) the Common Stock Deemed Outstanding immediately prior to such issuance or sale (or deemed issuance or sale) plus (B) the aggregate number of shares
        of Common Stock issued or sold (or deemed issued or sold) by the Company in such issuance or sale (or deemed issuance or sale).

       

      b)          Adjustment to Number of Warrant Shares Upon Adjustment to Exercise Price.  Upon each adjustment of the Exercise Price pursuant to Section 3(a), the
        number of Warrant Shares issuable upon the exercise of this Warrant Certificate immediately prior to any such adjustment shall be increased to a number of Warrant Shares equal to the quotient obtained by dividing:

       

      i.             the product of (A) the Exercise Price in effect immediately prior to any such adjustment multiplied by (B) the number of Warrant Shares issuable upon exercise
        of this Warrant Certificate immediately prior to any such adjustment; by

       

      ii.            the Exercise Price resulting from such adjustment.

       

      c)           Effect of Certain Events on Adjustment to Exercise Price.  For purposes of determining the adjusted Exercise Price under Section 3(a), the following
        shall be applicable:

       

      i.           Issuance of Options.  If the Company shall, at any time or from time to time after the date hereof, in any manner grant or sell any Options, whether or not
        such Options or the right to convert or exchange any Convertible Securities issuable upon the exercise of such Options are immediately exercisable, and the price per share (determined as provided in this Section 3(c)(i) and in Section
          3(c)(v)) for which Common Stock is issuable upon the exercise of such Options or upon the conversion or exchange of Convertible Securities issuable upon the exercise of such Options is less than the Exercise Price in effect immediately prior
        to the time of the granting or sale of such Options, then the total maximum number of shares of Common Stock issuable upon the exercise of such Options or upon conversion or exchange of the total maximum amount of Convertible Securities issuable
        upon the exercise of such Options shall be deemed to have been issued as of the date of granting or sale of such Options (and thereafter shall be deemed to be outstanding for purposes of adjusting the Exercise Price under Section 3(a)), at
        a price per share equal to the quotient obtained by dividing:

       

      (x)         the sum (which sum shall constitute the applicable consideration received for purposes of Section 3(a)) of (1) the total amount, if any, received or receivable by the Company
        as consideration for the granting or sale of all such Options, plus (2) the minimum aggregate amount of additional consideration payable to the Company upon the exercise of all such Options, plus (3), in the case of such Options which relate to
        Convertible Securities, the minimum aggregate amount of additional consideration, if any, payable to the Company upon the issuance or sale of all such Convertible Securities and the conversion or exchange of all such Convertible Securities, by

       

      
        

        10

        
          


        

      

      (y)          the total maximum number of shares of Common Stock issuable upon the exercise of all such Options or upon the conversion or exchange of all Convertible Securities issuable upon the
        exercise of all such Options.

       

      Except as otherwise provided in Section 3(c)(iii), no further adjustment of the Exercise Price shall be made upon the actual issuance of Common Stock or of Convertible Securities upon
        exercise of such Options or upon the actual issuance of Common Stock upon conversion or exchange of Convertible Securities issuable upon exercise of such Options.

       

      ii.          Issuance of Convertible Securities.  If the Company shall, at any time or from time to time after the Issue Date, in any manner grant or sell any Convertible
        Securities, whether or not the right to convert or exchange any such Convertible Securities is immediately exercisable, and the price per share (determined as provided in this Section 3(c)(ii) and in Section 3(c)(v)) for which
        Common Stock is issuable upon the conversion or exchange of such Convertible Securities is less than the Exercise Price in effect immediately prior to the time of the granting or sale of such Convertible Securities, then the total maximum number of
        shares of Common Stock issuable upon conversion or exchange of the total maximum amount of such Convertible Securities shall be deemed to have been issued as of the date of granting or sale of such Convertible Securities (and thereafter shall be
        deemed to be outstanding for purposes of adjusting the Exercise Price pursuant to Section 3(a)), at a price per share equal to the quotient obtained by dividing:

       

      (x)          the sum (which sum shall constitute the applicable consideration received for purposes of Section 3(a)) of (1) the total amount, if any, received or receivable by the Company
        as consideration for the granting or sale of such Convertible Securities, plus (2) the minimum aggregate amount of additional consideration, if any, payable to the Company upon the conversion or exchange of all such Convertible Securities, by

       

      (y)          the total maximum number of shares of Common Stock issuable upon the conversion or exchange of all such Convertible Securities.

       

      Except as otherwise provided in Section 3(c)(iii), (A) no further adjustment of the Exercise Price shall be made upon the actual issuance of Common Stock upon conversion or exchange of such
        Convertible Securities and (B) no further adjustment of the Exercise Price shall be made by reason of the issue or sale of Convertible Securities upon exercise of any Options to purchase any such Convertible Securities for which adjustments of the
        Exercise Price have been made pursuant to the other provisions of this Section 3(c).

       

      iii.             Change in Terms of Options or Convertible Securities.  From the Issue Date until the first anniversary of the Issuance Date, the Company shall not change
        (A) the total amount received or receivable by the Company as consideration for the granting or sale of any Options or Convertible Securities referred to in Section 3(c)(i) or (ii), (B) the minimum aggregate amount of additional
        consideration, if any, payable to the Company upon the exercise of any Options or upon the issuance, conversion or exchange of any Convertible Securities referred to in Section 3(c)(i) or (ii), (C) the rate at which Convertible Securities
        referred to in Section 3(c)(i) or (ii) are convertible into or exchangeable for Common Stock, or (D) the maximum number of shares of Common Stock issuable in connection with any Options referred to in Section 3(c)(i) or any
        Convertible Securities referred to in Section 3(c)(ii) (in each case, other than in connection with an Excluded Issuance) without the prior written consent of the Holder.

       

      
        

        11

        
          


        

      

      iv.              [RESERVED].

       

      v.             Calculation of Consideration Received.  If the Company shall, at any time or from time to time after the Issue Date, issue or sell, or pursuant to Section

          3(c) be deemed to have issued or sold, any shares of Common Stock, Options or Convertible Securities: (A) for cash, the consideration received therefor shall be deemed to be the net amount received by
        the Company therefor; (B) for Marketable Securities, the amount of consideration received therefor shall be deemed to be the market price (as reflected on any securities exchange, quotation system or association or similar pricing system covering
        such security) for such securities as of the end of business on the date of receipt of such securities; (C) for consideration other than cash or Marketable Securities, the amount of consideration received therefor shall be deemed to be the fair
        value of such consideration; (D) for no specifically allocated consideration in connection with an issuance or sale of other securities of the Company, together comprising one integrated transaction, the amount of consideration received therefor
        shall be deemed to be to be the fair value of such portion of the aggregate consideration received by the Company in such transaction as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be, issued
        in such transaction; or (E) to the owners of the non‐surviving entity in connection with any merger in which the Company is the surviving corporation, the amount of consideration received therefor shall be deemed to be the fair value of such
        portion of the net assets and business of the non-surviving entity as is attributable to such shares of Common Stock, Options or Convertible Securities, as the case may be, issued to such owners.  The net amount of any cash consideration and the
        fair value of any consideration other than cash or Marketable Securities shall be determined in good faith jointly by the Board of Directors of the Company and the Holder.

       

      vi.              Record Date.  For purposes of any adjustment to the Exercise Price or the number of Warrant Shares in accordance with this Section 3, in case the
        Company shall take a record of the holders of its Common Stock for the purpose of entitling them (A) to receive a dividend or other distribution payable in Common Stock, Options or Convertible Securities or (B) to subscribe for or purchase Common
        Stock, Options or Convertible Securities, then such record date shall be deemed to be the date of the issue or sale of the shares of Common Stock deemed to have been issued or sold upon the declaration of such dividend or the making of such other
        distribution or the date of the granting of such right of subscription or purchase, as the case may be.

       

      vii.            Treasury Shares.  The number of shares of Common Stock outstanding at any given time shall not include shares owned or held by or for the account of the
        Company or any of its wholly-owned subsidiaries, and the disposition of any such shares (other than the cancellation or retirement thereof or the transfer of such shares among the Company and its wholly-owned subsidiaries) shall be considered an
        issue or sale of Common Stock for the purpose of this Section 3.

       

      
        

        12

        
          


        

      

      d)          Adjustment to Exercise Price and Warrant Shares Upon Dividend, Subdivision or Combination of Common Stock.  If the Company shall, at any time or from time to
        time after the Issue Date, (i) pay a dividend or make any other distribution upon the Common Stock or any other capital stock of the Company payable in shares of Common Stock or in Options or Convertible Securities, or (ii) subdivide (by any stock
        split, recapitalization or otherwise) its outstanding shares of Common Stock into a greater number of shares, the Exercise Price in effect immediately prior to any such dividend, distribution or subdivision shall be proportionately reduced and the
        number of Warrant Shares issuable upon exercise of this Warrant Certificate shall be proportionately increased.  If the Company at any time combines (by combination, reverse stock split or otherwise) its outstanding shares of Common Stock into a
        smaller number of shares, the Exercise Price in effect immediately prior to such combination shall be proportionately increased and the number of Warrant Shares issuable upon exercise of this Warrant Certificate shall be proportionately decreased. 
        Any adjustment under this Section 3(d) shall become effective at the close of business on the date the dividend, subdivision or combination becomes effective.

       

      e)           Adjustment to Exercise Price and Warrant Shares Upon Reorganization, Reclassification, Consolidation or Merger.  In the event of any (A) capital
        reorganization of the Company or (B) reclassification of the stock of the Company (other than a change in par value or from par value to no par value or from no par value to par value or as a result of a stock dividend or subdivision, split-up or
        combination of shares) in each case which entitles the holders of Common Stock to receive (either directly or upon subsequent liquidation) stock, securities or assets with respect to or in exchange for Common Stock:

       

      (x)          this Warrant Certificate shall, immediately after such transaction, remain outstanding and shall thereafter, in lieu of or in addition to (as the case may be) the number of Warrant
        Shares then exercisable under this Warrant Certificate, be exercisable for the kind and number of shares of stock or other securities or assets of the Company or of the successor Person resulting from such transaction to which the Holder would have
        been entitled upon such transaction if the Holder had exercised this Warrant Certificate in full immediately prior to the time of such transaction and acquired the applicable number of Warrant Shares then issuable hereunder as a result of such
        exercise; and

       

      (y)         appropriate adjustment (in form and substance satisfactory to the Holder) shall be made with respect to the Holder’s rights under this Warrant Certificate to insure that the provisions
        of this Section 3 shall thereafter be applicable, as nearly as possible, to this Warrant Certificate in relation to any shares of stock, securities or assets thereafter acquirable upon exercise of this Warrant Certificate (including, in the
        case of any transaction in which the successor or purchasing Person is other than the Company, an immediate adjustment in the Exercise Price to the value per share for the Common Stock reflected by the terms of such transaction, and a corresponding
        adjustment immediately shall be made to the number of Warrant Shares acquirable upon exercise of this Warrant Certificate, without regard to any limitations or restrictions on exercise, if the value so reflected is less than the Exercise Price in
        effect immediately prior to such transaction).

       

      
        

        13

        
          


        

      

      The provisions of this Section 3(e) shall similarly apply to successive reorganizations and reclassifications.

       

      Notwithstanding anything to the contrary contained herein, with respect to any corporate event or other transaction contemplated by this Section 3(e), the Holder shall have the right to
        elect, prior to the consummation of such event or transaction, to exercise this Warrant instead of giving effect to Section 3(e).

       

      f)           Other Dividends and Distributions.  If the Company shall, at any time or from time to time after the Issue Date, make or declare, or fix a record date for
        the determination of holders of Common Stock entitled to receive, a dividend or any other distribution payable in cash, securities of the Company (other than a dividend or distribution of shares of Common Stock, Options or Convertible Securities in
        respect of outstanding shares of Common Stock) or other property, then, and in each such event, the Company shall ensure that provisions are made so that the Holder shall receive upon exercise of this Warrant Certificate, in addition to the number
        of Warrant Shares receivable thereupon, the kind and amount of cash, securities of the Company or other property which the Holder would have been entitled to receive had this Warrant Certificate been exercised in full into Warrant Shares on the
        date of such event and had the Holder thereafter, during the period from the date of such event to and including the date of exercise, retained such cash, securities or other property receivable by them as aforesaid during such period, giving
        application to all adjustments called for during such period under this Section 3 with respect to the rights of the Holder; provided that no such provision shall be made if the Holder
        receives, simultaneously with the distribution to the holders of Common Stock, a dividend or other distribution of such securities, cash or other property in an amount equal to the amount of such securities, cash or other property as the Holder
        would have received if this Warrant Certificate had been exercised in full into Warrant Shares on the date of such event.

       

      g)          Certain Events.  If any event of the type contemplated by the provisions of this Section 3 but not expressly provided for by such provisions
        (including, without limitation, the granting of stock appreciation rights, phantom stock rights or other rights with equity features) occurs, then the Board of Directors of the Company shall make an appropriate adjustment in the Exercise Price and
        the number of Warrant Shares issuable upon exercise of this Warrant Certificate so as to protect the rights of the Holder in a manner consistent with the provisions of this Section 3; provided that no such adjustment pursuant to
        this Section 3(g) shall increase the Exercise Price or decrease the number of Warrant Shares issuable as otherwise determined pursuant to this Section 3.

       

      
        

        14

        
          


        

      

      h)           Certificate as to Adjustment.  As promptly as reasonably practicable following any adjustment of the Exercise Price, but in any event not later than three
        business days thereafter, the Company shall furnish to the Holder a certificate of an executive officer setting forth in reasonable detail such adjustment and the facts upon which it is based and certifying the calculation thereof.  As promptly as
        reasonably practicable following the receipt by the Company of a written request by the Holder, but in any event not later than three business days thereafter, the Company shall furnish to the Holder a certificate of an executive officer certifying
        the Exercise Price then in effect and the number of Warrant Shares or the amount, if any, of other shares of stock, securities or assets then issuable upon exercise of this Warrant Certificate.

       

      i)            Fundamental Transaction. If, at any time while this Warrant is outstanding, the Company effects a Fundamental Transaction then:

       

      
        
          	

                	i.	
                  if the consideration to be received by the holders of the Company’s Common Stock is cash and/or Marketable Securities, this Warrant shall be deemed automatically exercised, in full, without the requirement to deliver any Notice of
                    Exercise, immediately prior to the closing of such Fundamental Transaction and the Holder shall receive, in the same proportions as the holders of the Company’s Common Stock, such amounts of cash and/or Marketable Securities as the
                    holders of the Company’s Common Stock (and if the holders of Common Stock are given any choice as to the cash or Marketable Securities to be received in such Fundamental Transaction, then the Holder shall be given the same choice); and

                


        

      

       

      
        

        15

        
          


        

      

      
        
          	 	ii.	
                  if the consideration to be received by the holders of the Company’s Common Stock is not cash and/or Marketable Securities (an “Illiquid Fundamental Transaction”), then, unless exercised by the Holder (in the Holder’s sole
                    discretion) prior to the consummation of such Illiquid Fundamental Transaction, (x) this Warrant shall remain outstanding and (y) upon any subsequent exercise of this Warrant, the Holder shall have the right to receive, for each Warrant
                    Share that would have been issuable upon such exercise immediately prior to the occurrence of such Illiquid Fundamental Transaction, at the option of the Holder, the number of shares of Common Stock of the successor or acquiring
                    corporation or of the Company, if it is the surviving corporation, and any additional consideration (the “Alternate Consideration”) receivable as a result of such Illiquid Fundamental Transaction by a holder of the number of
                    shares of Common Stock for which this Warrant is exercisable immediately prior to such Illiquid Fundamental Transaction.  For purposes of any such exercise, the determination of the Exercise 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 Illiquid Fundamental Transaction, and the Company shall apportion the Exercise 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 an Illiquid Fundamental Transaction, then the Holder shall be given the same choice as to the Alternate Consideration it receives upon any exercise of this Warrant following such Illiquid Fundamental Transaction.  The
                    Company shall cause any successor entity in an Illiquid Fundamental Transaction in which the Company is not the survivor (the “Successor Entity”) to assume in writing all of the obligations of the Company under this Warrant
                    pursuant to written agreements in form and substance reasonably satisfactory to the Holder and approved by the Holder (without unreasonable delay) prior to such Illiquid Fundamental Transaction and shall, at the option of the Holder,
                    deliver to the Holder in exchange for this Warrant a security of the Successor Entity evidenced by a written instrument substantially similar in form and substance to this Warrant which is exercisable for a corresponding number of
                    shares of capital stock of such Successor Entity (or its parent entity) equivalent to the shares of Common Stock acquirable and receivable upon exercise of this Warrant (without regard to any limitations on the exercise of this Warrant)
                    prior to such Illiquid Fundamental Transaction, and with an exercise price which applies the Exercise Price hereunder to such shares of capital stock (but taking into account the relative value of the shares of Common Stock pursuant to
                    such Illiquid Fundamental Transaction and the value of such shares of capital stock, such number of shares of capital stock and such Exercise Price being for the purpose of protecting the economic value of this Warrant immediately prior
                    to the consummation of such Illiquid Fundamental Transaction), and which is reasonably satisfactory in form and substance to the Holder. Upon the occurrence of any such Illiquid Fundamental Transaction, the Successor Entity shall
                    succeed to, and be substituted for (so that from and after the date of such Illiquid Fundamental Transaction, the provisions of this Warrant and the other Loan Documents referring to the “Company” shall refer instead to the Successor
                    Entity), and may exercise every right and power of the Company and shall assume all of the obligations of the Company under this Warrant and the other Loan Documents with the same effect as if such Successor Entity had been named as the
                    Company herein.

                


        

      

       

      j)           Calculations. All calculations under this Section 3 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 3, 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 treasury shares, if any) issued and outstanding.

       

      
        

        16

        
          


        

      

      k)           Notice to Allow Exercise by Holder. If (A) the 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 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, (E) the Company shall authorize the voluntary or involuntary
        dissolution, liquidation or winding up of the affairs of the Company, or (F) the Company seeks to engage in a Fundamental Transaction, then, in each case, the Company shall cause to be mailed to the Holder at its last address as it shall appear
        upon the Warrant Register (as defined below) of the Company, 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 Fundamental Transaction, 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 Fundamental Transaction, reclassification, consolidation, merger, sale, transfer or share exchange;
        provided that the failure to mail such notice or any defect therein or in the mailing thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice required to be provided
        hereunder may contain information that constitutes material, non-public information regarding the Company or any of the Subsidiaries, the Company shall obtain the Holder’s prior consent to receipt of such notice. If the Holder declines to receive
        any such notice pursuant to the immediately preceding sentence, the Company shall not be deemed to have breached its obligation to deliver such notice hereunder.  The Holder shall remain entitled to exercise this Warrant 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.

       

      Section 4.             Transfer of Warrant.

       

      a)           Transferability.  Subject to compliance with any applicable securities laws, this Warrant and all rights hereunder (including, without limitation, any
        registration rights) are transferable, in whole or in part, (i) to any transferee who is not an Affiliate of the Holder upon five (5) Trading Days’ prior notice to the Company or (ii) to any Affiliate of the Holder upon notice to the Company and,
        in each case, surrender of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant substantially in the form attached hereto duly executed by the Holder or its agent or
        attorney and funds sufficient to pay any transfer taxes payable upon the making of such transfer.  Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants in the name of the assignee or
        assignees, as applicable, and in the denomination or denominations specified in such instrument of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant shall promptly be
        cancelled. Notwithstanding anything herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company unless the Holder has assigned this Warrant in full, in which case, the Holder shall surrender this
        Warrant to the Company within two (2) Trading Days of the date the Holder delivers to the Company a completed Assignment Form in the form attached hereto duly executed by the Holder assigning all or any portion of this Warrant.  This Warrant, if
        properly assigned in accordance herewith, may be exercised by a new holder for the purchase of Warrant Shares without having a new Warrant issued.

       

      
        

        17

        
          


        

      

      b)           New Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the Company, together with a
        written notice specifying the names and denominations in which new Warrants are to be issued, signed by the Holder or its agent or attorney.  Subject to compliance with Section 4(a), as to any transfer which may be involved in such division
        or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated as of the
        Issue Date and shall be identical with this Warrant except as to the number of Warrant Shares issuable pursuant thereto.

       

      c)          Transferee Representations.  If, at the time of the surrender of this Warrant in
          connection with any transfer of this Warrant, the transfer of this Warrant shall not be eligible for resale without volume or manner-of-sale restrictions or current
          public information requirements pursuant to Rule 144, the Company may require, as a condition of allowing such transfer, that the Holder or transferee of this Warrant, as the case may be, deliver a written statement from the transferee to the Company certifying that the transferee is an “accredited investor” as defined in Rule 501(a) under the Securities Act, making the representations
          and certifications set forth in Section 4(e) of this Warrant and making such additional representations as the Company may, after consultation with its counsel,
          require in order to confirm compliance with applicable securities laws.

       

      d)          Warrant Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant Register”), in
        the name of the record Holder hereof from time to time.  The Company may deem and treat the registered Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and for all other
        purposes, absent actual notice to the contrary.

       

      e)           Representation by the Holder.  The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any exercise hereof,
        will acquire the Warrant Shares issuable upon such exercise, for its own account and not with a view to or for distributing or reselling such Warrant Shares or any part thereof in violation of the Securities Act or any applicable state securities
        law, except pursuant to sales registered or exempted under the Securities Act.

       

      
        

        18

        
          


        

      

      Section 5.             Miscellaneous.

        

      

      a)           No Rights as Stockholder Until Exercise.  This Warrant does not entitle the Holder to any voting rights, dividends or other rights as a stockholder of the
        Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.

       

      b)          Loss, Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably satisfactory to it of the
        loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant Shares, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of this Warrant,
        shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate, if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such
        cancellation, in lieu of such Warrant or stock certificate.

       

      c)          Removal of Restrictive Legends.  Neither this Warrant nor any certificates evidencing Warrant Shares shall contain any legend restricting the transfer thereof
        in any of the following circumstances: (A) following any sale of this Warrant or such Warrant Shares issued or delivered to the Holder under or in connection herewith pursuant to Rule 144, (B) if this Warrant or such Warrant Shares are eligible for
        sale under Rule 144(b)(1), or (C) if such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the Commission) (collectively, the “Unrestricted
          Conditions”).  In such circumstances, the Company shall seek to cause its counsel to issue a legal opinion to the Transfer Agent if required by such Transfer Agent to effect the issuance of Warrant Shares, without a restrictive legend or
        removal of the legend hereunder.  If the Unrestricted Conditions are met at the time of issuance of this Warrant, the Warrant Shares or such other shares of Common Stock, then this Warrant, Warrant Shares or other Common Stock, as the case may be,
        shall be issued free of all legends.

       

      d)         Replacement Warrant.  The Company agrees that at such time as the Unrestricted Conditions have been satisfied it
        shall promptly (but in any event within ten (10) Business Days) following written request from the Holder issue a replacement Warrant or replacement Warrant Shares or replacement shares in respect of such other Common Stock, as the case may be,
        free of all restrictive legends (“Unlegended Shares”).

       

      e)          Rule 144 Compliance.  With a view to making available to the Holder the benefits of Rule 144 under the Securities Act and any other rule or regulation of the
        SEC that may at any time permit a holder to sell securities of the Company to the public without registration, the Company shall:

       

      
        
          	

                	i.	
                  use reasonable best efforts to make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities Act, including to file with the SEC in a timely manner all reports and other
                    documents required of the Company under the Securities Act and the Exchange Act; and

                


        

      

       

      
        

        19

        
          


        

      

      
        
          	

                	ii.	
                  furnish to the Holder, promptly upon request, a written statement by the Company as to its compliance with the reporting requirements of Rule 144 under the Securities Act and of the Securities Act and the Exchange Act, a copy of the
                    most recent annual or quarterly report of the Company, and such other reports and documents so filed or furnished by the Company as such holder may reasonably request in connection with the sale of the Warrant Shares without
                    registration.

                


        

      

       

      f)           Authorized Shares.  The Company covenants that, during the period this Warrant is outstanding, it will reserve from its authorized and unissued Common Stock
        a sufficient number of shares to provide for the issuance of the Warrant Shares upon the exercise of any purchase rights under this Warrant.  The Company further covenants that its issuance of this Warrant shall constitute full authority to its
        officers who are charged with the duty of issuing the necessary Warrant Shares upon the exercise of the purchase rights under this Warrant.  The Company will take all such action as may be necessary to assure that such Warrant Shares may be issued
        as provided herein without violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Stock is listed.  The Company covenants that all Warrant Shares which may be issued upon the exercise of
        the purchase rights represented by this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Shares in accordance herewith, be duly authorized, validly issued, fully paid and nonassessable and
        free from all taxes, liens and charges created by the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such issue).

       

      g)          No Impairment.  Except and to the extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending
        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 of this Warrant, but will at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary or appropriate to protect the rights of Holder as set forth in this Warrant against
        impairment.  Without limiting the generality of the foregoing, the Company will (i) not increase the par value of any Warrant Shares above the amount payable therefor upon such exercise immediately prior to such increase in par value, (ii) take all
        such action as may be necessary or appropriate in order that the Company may validly and legally issue unrestricted, fully paid and nonassessable Warrant Shares upon the exercise of this Warrant, and (iii) use commercially reasonable efforts to
        obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof, as may be, necessary to enable the Company to perform its obligations under this Warrant.  Before taking any action which would
        result in an adjustment in the number of Warrant Shares for which this Warrant is exercisable or in the Exercise Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any public
        regulatory body or bodies having jurisdiction thereof.

       

      
        

        20

        
          


        

      

      h)           Governing Law.  This Warrant and the rights and obligations of the parties hereunder shall be governed by, and construed in accordance with, the law of the
        State of New York, without regard to principles of conflicts of laws that would result in the application of the laws of any other jurisdiction.

       

      i)            Submission to Jurisdiction.  The Company agrees that any suit, action or proceeding with respect to this Warrant or any judgment entered by any court in
        respect thereof may be brought initially in the federal or state courts in New York, New York or in the courts of its own corporate domicile and irrevocably submits to the exclusive jurisdiction of each such court for the purpose of any such suit,
        action, proceeding or judgment.  This Section is for the benefit of the Holder only and, as a result, the Holder shall not be prevented from taking proceedings in any other courts with jurisdiction.  To the extent allowed by any applicable law, the
        Holder may take concurrent proceedings in any number of jurisdictions.

       

      j)            Waiver of Venue, Etc.  The Company irrevocably waives to the fullest extent permitted by law any objection that it may now or hereafter have to the laying
        of the venue of any suit, action or proceeding arising out of or relating to this Warrant and hereby further irrevocably waives to the fullest extent permitted by law any claim that any such suit, action or proceeding brought in any such court has
        been brought in an inconvenient forum.  A final judgment (in respect of which time for all appeals has elapsed) in any such suit, action or proceeding shall be conclusive and may be enforced in any court to the jurisdiction of which the Company is
        or may be subject, by suit upon judgment.

       

      k)        Waiver of Jury Trial.  THE COMPANY AND THE HOLDER HEREBY IRREVOCABLY WAIVE, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY
        JURY IN ANY SUIT, ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS WARRANT OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

       

      l)            No Waiver.  No failure on the part of the Holder to exercise and no delay in exercising, and no course of dealing with respect to, any right, power or
        privilege under this Warrant shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege under this Warrant preclude any other or further exercise thereof or the exercise of any other right, power or
        privilege.  The remedies provided herein are cumulative and not exclusive of any remedies provided by law.

       

      m)         Expenses.  If the Company fails to comply with any provision of this Warrant, which results in any material damages to the Holder, the Company shall pay to the
        Holder such amounts as shall be sufficient to cover any actual, reasonable and documented attorneys’ fees, including those of appellate proceedings, incurred by the Holder in collecting any amounts due pursuant hereto or in otherwise enforcing any
        of its rights, powers or remedies hereunder.

       

      
        

        21

        
          


        

      

      n)          Notices.  All notices, requests, instructions, directions and other communications provided for herein (including any modifications of, or waivers, requests or
        consents under, this Warrant) shall be given or made in writing (including by telecopy or email) delivered, if to the Company or the Holder, to its address specified on the signature pages hereto, or at such other address as shall be designated by
        such party in a written notice to the other party.  Except as otherwise provided in this Warrant, all such communications shall be deemed to have been duly given upon receipt of a legible copy thereof, in each case given or addressed as aforesaid. 
        All such communications provided for herein by telecopy shall be confirmed in writing promptly after the delivery of such communication (it being understood that non-receipt of written confirmation of such communication shall not invalidate such
        communication).

       

      o)          Limitation of Liability.  No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase Warrant Shares, and
        no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder for the purchase price of any Common Stock or as a stockholder of the Company, whether such liability is asserted by the Company or by
        creditors of the Company.

       

      p)          Remedies.  The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled to seek specific
        performance of its rights under this Warrant.  The Company agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to
        assert the defense in any action for specific performance that a remedy at law would be adequate.

       

      q)          Successors and Assigns.  Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall be binding upon and inure to
        the benefit of the successors and permitted assigns of the Company and the successors and permitted assigns of the Holder.  The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and shall
        be enforceable by the Holder or any holder of Warrant Shares.

       

      r)           Amendments, Etc.  Except as otherwise expressly provided in this Warrant, any provision of this Warrant may be modified or supplemented only by an instrument
        in writing signed by the Company and the Holder.

       

      s)          Severability.  If any provision hereof is found by a court to be invalid or unenforceable, to the fullest extent permitted by any applicable Law the parties
        agree that such invalidity or unenforceability shall not impair the validity or enforceability of any other provision hereof.

       

      t)            Captions.  The captions and section headings appearing herein are included solely for convenience of reference and are not intended to affect the
        interpretation of any provision of this Warrant.

       

      u)           Counterparts.  This Warrant may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any
        of the parties hereto may execute this Warrant by signing any such counterpart.
