                  receive, upon exercise of this Warrant, the same amount and kind of securities, cash or property as it would have been entitled to receive upon the occurrence of such Change of Control if it had been, immediately prior to such Change of
                  Control, the holder of the number of Warrant Shares then issuable upon exercise in full of this Warrant without regard to any limitations on exercise contained herein, and the holder of this Warrant shall no longer have the right to

              Method of Exercise. While this Warrant remains outstanding and exercisable, the holder may exercise, in whole or in
                  part, the purchase rights evidenced hereby. Such exercise shall be effected by:

              In lieu of exercising this Warrant as specified in this Section 4(a)(ii), the holder may convert this Warrant, in whole or in part, into a number of Shares determined by dividing (a) the aggregate fair market value of the Shares issuable
                upon exercise of this Warrant (or lesser number of shares in the case of a partial exercise) minus the aggregate Exercise Price of such Shares by (b) the fair market value of one Share. The fair market value of the Shares shall be the
                closing price of the Shares reported for the business day immediately before the holder delivers its notice of exercise to the Company

            


      

      

      	

            	b.	
              Exercise Period. This Warrant shall be immediately exercisable upon the Effective Date in the amount of 603,386 Shares.
                  This Warrant shall cease to be exercisable upon the expiration of this Warrant pursuant to Section 16 hereof.

            


      

      

      	

            	5.	
              Certificates for Shares. Upon the exercise of the purchase rights evidenced by this Warrant, one or more certificates or
                  book-entry notations for the number of Shares so purchased and, if this Warrant has not been fully exercised or converted and has not expired, a new Warrant representing the Shares not so acquired, shall be issued as soon as practicable
                  thereafter.

            


      

      

      	

            	6.

            	7.	
              Adjustment of Exercise Price and Number of Shares. The number of and kind of securities purchasable upon exercise of
                  this Warrant and the Exercise Price shall be subject to adjustment from time to time as follows:

            


       

      

      
        
          


      

      	

            	a.	
              Subdivisions, Combinations and Other Issuances. If the Company declares or pays a dividend or distribution on the shares
                  of Common Stock payable in common stock or other securities or property (other than cash), then upon exercise of this Warrant, for each Share acquired, the holder shall receive, without additional cost to the holder, the total number and
                  kind of securities and property which holder would have received had the holder owned the Shares of record as of the date the dividend or distribution occurred. If the Company subdivides the outstanding shares of Common Stock by
                  reclassification or otherwise into a greater number of shares, the number of Shares purchasable hereunder shall be proportionately increased and the Exercise Price shall be proportionately decreased. If the outstanding shares of Common
                  Stock are combined or consolidated, by reclassification or otherwise, into a lesser number of shares, the Exercise Price shall be proportionately increased and the number of Shares shall be proportionately decreased. Any adjustment under
                  this Section 7(a) shall become effective at the close of business on the date the subdivision or combination becomes effective, or as of the record date of such dividend, or in the event that no record date is fixed, upon the making of
                  such dividend.

            


      

      

      	

            	b.	
              Reclassification, Reorganization and Consolidation. Upon any event whereby all of the outstanding shares of Common Stock
                  are reclassified, exchanged, combined, substituted, or replaced for, into, with or by Company securities of a different class and/or series, then from and after the consummation of such event, this Warrant will be exercisable for the
                  number, class and series of Company securities that holder would have received had the Shares been outstanding on and as of the consummation of such event, and subject to further adjustment thereafter from time to time in accordance with
                  the provisions of this Warrant.

            


      

      

      	

            	c.	
              Notice of Adjustment and Certain Events. The Company shall provide the holder with not less than 5 days prior written
                  notice of, including a description of the material facts surrounding, any of the following events: (a) declaration of any dividend or distribution upon its Common Stock, whether in cash, property, stock, or other securities and whether or
                  not a regular cash dividend; (b) offering for subscription pro rata to the holders of any class or series of its stock any additional shares of stock of any class or series or other rights; (c) effecting any reclassification or
                  recapitalization of Common Stock; (d) the merger or consolidation with or into any other corporation, or sale, lease, license, or conveyance of all or substantially all of its assets, or liquidation, dissolution or winding up; or (e) when
                  any other adjustment is required to be made in the number or kind of shares purchasable upon exercise of this Warrant, or in the Exercise Price. When any adjustment is required to be made in the number or kind of shares purchaseable upon
                  exercise of this Warrant, or in the Exercise Price, the Company shall promptly compute such adjustment or readjustment in accordance with the provisions hereof and prepare a certificate showing such adjustment or readjustment, and shall
                  mail such certificate to the holder of this Warrant in accordance with the notice provisions of Section 17. The certificate shall set forth such adjustment or readjustment and indicate the number of shares of Common Stock and the Exercise
                  Price in effect after such adjustment or readjustment. The provisions of this Section 7(c) shall similarly apply to successive reclassifications, exchanges, combinations substitutions, replacements or other similar events.

            


      

      

      
        
          


      

      	

            	8.	
              No Fractional Shares or Scrip. No fractional shares or scrip representing fractional shares shall be issued upon the exercise of this Warrant, but in lieu of such fractional shares the Company shall make a
                cash payment therefor on the basis of the Exercise Price then in effect.

            


      

      

      	

            	9.	
              Reservation of Shares. During the period between the Effective Date and the Expiration Date, the Company shall at all
                  times reserve and keep available out of its authorized but unissued shares of Common Stock or other securities constituting Shares, solely for the purpose of issuance upon the exercise of this Warrant, the maximum number of Shares
                  issuable upon the exercise of this Warrant, and the par value per Share shall at all times be less than or equal to the applicable Exercise Price.

            


      

      

      	

            	10.	
              Representations of the Company. The Company represents that all corporate actions on the part of the Company, its
                  officers, directors and stockholders necessary for the sale and issuance of this Warrant have been taken. The Company will pay all original issue and transfer taxes, if any, with respect to the issue and delivery of the Shares pursuant
                  hereto and all other fees and expenses necessarily incurred by the Company in connection herewith.

            


      

      

      	

            	11.	
              Representations and Warranties by the Holder. The holder of this Warrant represents and warrants to the Company as
                  follows:

            


      

      

      	

            	a.	
              This Warrant and the Shares issuable upon exercise thereof are being acquired for its own account, for investment and not with a view to, or for resale in connection with, any distribution or public offering
                thereof within the meaning of the Securities Act of 1933, as amended (the "Act"). Upon exercise of this Warrant, the holder of this Warrant shall, if so requested by the Company, confirm in writing, in a form satisfactory to the
                Company, that the securities issuable upon exercise of this Warrant are being acquired for investment and not with a view toward distribution or resale.

            


      

      

      	

            	b.	
              The holder of this Warrant understands that this Warrant and the Shares have not been registered under the Act by reason of their issuance in a transaction exempt from the registration and prospectus delivery
                requirements of the Act pursuant to Section 4(a)(2) thereof, and that they must be held by the holder indefinitely, and that the holder must therefore bear the economic risk of such investment indefinitely, unless a subsequent disposition
                thereof is registered under the Act or is exempted from such registration.

            


      

      

      	

            	c.	
              The holder of this Warrant has such knowledge and experience in financial and business matters that it is capable of evaluating the merits and risks of the purchase of this Warrant and the Shares purchasable
                pursuant to the terms of this Warrant and of protecting its interests in connection therewith.

            


       

      

      
        
          


      

      	

            	d.	
              The holder of this Warrant is aware of the Company’s business affairs and financial condition and has received or has had full access to all the information it considers necessary or appropriate to make an
                informed investment decision with respect to the acquisition of this Warrant and its underlying securities. The holder of this Warrant further has had an opportunity to ask questions and receive answers from the Company regarding the terms
                and conditions of the offering of this Warrant and its underlying securities and to obtain additional information (to the extent the Company possessed such information or could acquire it without unreasonable effort or expense) necessary to
                verify any information furnished to the holder of this Warrant or to which the holder has access.

            


      

      

      	

            	e.	
              The holder of this Warrant is able to bear the economic risk of the purchase of the Shares pursuant to the terms of this Warrant.

            


      

      

      	

            	f.	
              The holder of this Warrant is an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated under the Act.

            


      

      

      	

            	12.	
              Restrictive Legend. The Shares shall be stamped or imprinted with a legend in substantially the following form:

            


      

      

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
        1933, AS AMENDED. SUCH SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER THE ACT AND ANY APPLICABLE STATE SECURITIES LAWS. COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND
        RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY AT THE PRINCIPAL EXECUTIVE OFFICES OF THE COMPANY.

      

      

      	

            	13.	
              Warrants Transferable.

            


      

      

      	

            	a.	
              This Warrant, and any Shares issued hereunder, may not be sold, assigned or otherwise transferred by the holder hereof until six months after the Effective Date, except for an assignment or transfer of this
                Warrant, in whole or in part, by Neptune to an affiliate of Neptune, excluding any affiliate of the Company that is a natural person. Thereafter, this Warrant and the Shares may be offered, sold or otherwise transferred or disposed, in
                whole or in part, by the holder. Any sale, transfer or assignment of this Warrant or the Shares issued hereunder shall be subject to compliance with the terms and conditions of Section 13(b) and applicable federal and state securities laws.

            


      

      

      
        
          


      

      	

            	b.	
              Any transfer of this Warrant shall require surrender of this Warrant properly endorsed or accompanied by written instructions of transfer. With respect to any offer, sale or other disposition of this Warrant or
                the Shares, the holder hereof agrees to give written notice to the Company prior thereto, describing briefly the manner thereof, together with a written opinion of the holder’s counsel, or other evidence, if requested by the Company, to the
                effect that such offer, sale or other disposition may be effected without registration or qualification (under the Act as then in effect or any federal or state securities law then in effect) of this Warrant or the Shares and indicating
                whether or not under the Act certificates for this Warrant or the Shares to be sold or otherwise disposed of require any restrictive legend as to applicable restrictions on transferability in order to ensure compliance with such law;
                provided, however, that (i) the Company shall not require the holder to provide an opinion of counsel if the transfer is to any affiliate of the holder, provided that any such transferee is an “accredited investor” as defined in Regulation
                D promulgated under the Act, and additionally, (ii) the Company shall also not require an opinion of counsel if there is no material question as to the availability of Rule 144 promulgated under the Act. Upon receiving such written notice
                and reasonably satisfactory opinion or other evidence, if so requested, the Company, as promptly as practicable, shall notify the holder that the holder may sell or otherwise dispose of this Warrant or the Shares, all in accordance with the
                terms of the notice delivered to the Company. If a determination has been made pursuant to this Section 13 that the opinion of counsel for the holder or other evidence is not reasonably satisfactory to the Company, the Company shall so
                notify the holder promptly with details thereof after such determination has been made. Each certificate representing this Warrant or Shares transferred in accordance with this Section 13 shall bear a legend as to the applicable
                restrictions on transferability in order to ensure compliance with such laws, unless in the aforesaid opinion of counsel for the holder, such legend is not required in order to ensure compliance with such laws. The Company may issue stop
                transfer instructions to its transfer agent in connection with such restrictions.

                  other rights of a stockholder of the Company until exercise of this Warrant.

              Expiration of Warrant. This Warrant shall be exercisable in whole or in part, at any time and from time to time, until
                  ten years from the original issue date of this Warrant (the “Expiration Date”). If this Warrant has not been exercised prior to the Expiration Date, this Warrant shall be deemed to have been automatically exercised on the
                  Expiration Date by “cashless” conversion pursuant to Section 4(a)(iii).

            


       

      

      
        
          


      

      	

            	17.	
              Notices. Any notice, consent, claim, demand, waiver, or other communication under this Warrant have legal effect only if
                  in writing and addressed to a party to the address set forth below (or to such other address or such other person that a party may designate for itself from time to time in accordance with this Section). Notices sent in accordance with
                  this Section will be deemed effectively given: (a) when received, if delivered by hand, with signed confirmation of receipt; (b) when received, if sent by a nationally recognized overnight courier, signature required; (c) when sent, if by
