    COMMON
      STOCK PURCHASE WARRANT AGREEMENT

     

    JAVELIN
      PHARMACEUTICALS, INC., a Delaware corporation (the “Company”),
      hereby grants to AURORA CAPITAL LLC (the “Initial
      Holder”),
      subject to the terms set forth in this Common Stock Purchase Warrant Agreement
      (the “Warrant
      Agreement”),
      the
      right to exercise Common Stock Purchase Warrants (the “Warrants”)
      for
      the purchase from the Company of up to 10,184 shares (the “Shares”)
      of the
      Company’s Common Stock, at an exercise price of $2.49 per share, subject to
      adjustment from time to time pursuant to Section 3 hereof (the “Exercise
      Price”).
      The
      term “Common
      Stock”
means,
      unless the context otherwise requires, the Company’s Common Stock, par value
      $.001 per share, or other securities or property at the time deliverable upon
      the exercise of this Warrant.

     

    This
      Warrant had been originally issued to the Initial Holder by Intrac, Inc., a
      Nevada corporation (“Intrac”) in consideration of the February 9, 2004
      termination and cancellation of a May 5, 2003 engagement letter between the
      Initial Holder and Innovative Drug Delivery Systems, Inc., which became a
      wholly-owed subsidiary of Intrac in December 2004. Effective September 7, 2005,
      Intrac merged with and into the Company, and the Company assumed all outstanding
      warrants to purchase Intrac common stock on the same terms as the Intrac
      warrants, except exercisable for shares of the Company’s Common Stock.

     

    1.      Exercise.

     

    1.1    Timing
      of Exercise.
      The
      Warrants shall be exercisable at any time in whole or in part from time to
      time
      commencing as of the date hereof and expiring at 5:00 P.M., New York time,
      on
      February 8, 2009 (the “Expiration
      Date”),
      subject to earlier termination as provided herein, and may not be exercised
      thereafter.

     

    1.2    Manner
      of Exercise.
      The
      purchase rights evidenced by this Warrant Agreement shall be exercised by the
      Initial Holder or any person permitted by Section 6 hereof
      (collectively,

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    “the
      Holder”),
      by
      surrendering this Warrant Agreement, together with the Notice of Exercise in
      the
      form of Exhibit
      A
      annexed
      hereto duly executed by the Holder, to the Company at the address in Section
      11
      hereof for sending of notices, accompanied by payment (in cash, by wire transfer
      or by certified or official bank check or checks) of the applicable Exercise
      Price.

     

    1.3    Net
      Issue Exercise.

     

    (a)    In
      lieu
      of making payment a monetary payment as provided in Section 1.2 hereof upon
      exercise, the Holder may elect, in its sole discretion, to receive shares of
      Common Stock equal to the value (as determined below) of the Warrants then
      being
      exercised by surrender of this Warrant Agreement to the Company, together with
      the Notice of Exercise and notice of the net issue election. Thereupon, the
      Company shall issue to the Holder the number of Shares computed using the
      following formula:

     

    X
      =
      Y(A-B) / A

     

    Where:    
X
      = the
      number of Shares to be issued to the Holder pursuant to this Section
      1.3.

     

    Y=
      the
      number of Shares in respect of which the net issue exercise is being
      made.

     

    A=
      the
      current fair market value of one share of Common Stock.

     

    B=
      the
      Exercise Price at the time the net issue exercise is being made.

     

    (b)    For
      the
      purpose of this Section, the fair market value of the Shares shall mean with
      respect to each share of Common Stock:

     

    (i)    If
      the
      Shares are listed on any national securities exchange or quoted on the Nasdaq
      National Market, Nasdaq Small Cap Market or the OTC Bulletin Board, the average
      of the closing prices of the Shares, sold on the primary securities exchange
      or
      market on which the Shares are at the time listed or traded, for the ten (10)
      trading days immediately prior to the day the Notice of Exercise is received
      by
      the Company; or

     

    (ii)    If
      the
      Shares are not quoted on any national securities exchange or quoted on the
      Nasdaq National Market, Nasdaq Small Cap Market or the OTC Bulletin Board,
      the
      average of the mean between the highest bid and lowest asked price on such
      a day
      in the domestic over-the-counter market as reported by the National Quotation
      Bureau or any similar successor organization, for the thirty (30) calendar
      days
      immediately prior to the day the Notice of Exercise is received by the
      Company;

     

    (iii)    If
      there
      is no public market for the Shares, the price determined by the Board of
      Directors of the Company acting in good faith.

     

    1.4    Partial
      Exercise.
      This
      Warrant may be exercised for less than the full number of Shares available
      for
      exercise at the time the Notice of Exercise is submitted, in which case the
      number of Shares receivable upon the exercise of this Warrant as a whole, and
      the amount payable upon the exercise of this Warrant as a whole, shall be
      proportionately reduced. Upon any such partial exercise, the Company at its
      expense will forthwith issue to the Holder a new

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

       

    

    Warrant
      Agreement of like tenor calling for Warrants to purchase the number of shares
      of
      Common Stock as to which rights have not been exercised. 

     

    2.     
      Delivery
      of Stock Certificates Upon Exercise.
      As soon
      as practicable after the exercise of any Warrants, and in any event within
      five
      (5) business days thereafter, the Company, at its expense, will cause to be
      issued in the name of and delivered to the Holder or other person specified
      in
      the Notice of Exercise a certificate or certificates for the number of fully
      paid and non-assessable shares of Common Stock to which the Holder shall be
      entitled upon such exercise, subject to compliance with Section 7 hereof. Any
      shares of Common Stock as to which this Warrant is exercised shall be deemed
      issued on and as of the date of such exercise, and the Holder shall thereupon
      be
      deemed to be the owner of record of such Shares.

     

    3.     
      Anti-Dilution
      Adjustments.

     

    3.1    Change
      in Capitalization.
      If the
      Company shall at any time prior to the Expiration Date subdivide its outstanding
      Common Stock, by forward stock split or otherwise, or combine its outstanding
      Common Stock (including a reverse split), or issue additional shares of its
      Common Stock in payment of a stock dividend in respect of its Common Stock,
      the
      Shares shall forthwith be proportionately increased in the case of a subdivision
      or stock dividend, or proportionately decreased in the case of a combination,
      and the Exercise Price then applicable to the Shares covered by the unexercised
      portion of the Warrants shall forthwith be proportionately decreased in the
      case
      of a subdivision or stock dividend, or proportionately increased in the case
      of
      a combination.

     

    3.2    Reclassification.
      In case
      of any reclassification, capital reorganization or change of the outstanding
      Common Stock of the Company (other than as a result of a subdivision,
      combination or stock dividend covered by Section 3.1 hereof), at any time prior
      to the Expiration Date, then, as a condition of such reclassification,
      reorganization or change, lawful provision shall be made, and duly executed
      documents evidencing the same from the Company or its successor shall be
      delivered to the Holder, so that the Holder shall have the right prior to the
      Expiration Date to purchase, at a total price not to exceed that payable upon
      the exercise of the unexercised portion of the Warrants, the kind and amount
      of
      shares of stock and other securities and property receivable upon such
      reclassification, reorganization or change, by a holder of the number of shares
      of Common Stock of the Company which might have been purchased by the Holder
      immediately prior to such reclassification, reorganization or change, and in
      any
      such case appropriate provisions shall be made with respect to the rights and
      interest of the Holder to the end that the provisions hereof (including without
      limitation, provisions for the adjustment of the Exercise Price and of the
      number of Shares purchasable upon exercise of the Warrants) shall thereafter
      be
      applicable in relation to any shares of stock and other securities and property
      thereafter deliverable upon exercise hereof.

     

    3.3    Consolidation,
      Merger and Sale of Assets.
      In case
      of any consolidation of the Company with or a merger of the Company into another
      corporation or in case of any sale or conveyance and to another corporation
      of
      the property of the Company as an entirety or substantially as an entirety,
      upon
      any such consolidation, merger, sale or conveyance (i) the surviving entity
      or its parent corporation is a public reporting company under the Securities
      Exchange Act of 1934, as amended, and (ii) the consideration to be received
      by the holders of

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

     

    the
      Company’s Common Stock includes publicly traded equity securities in the
      surviving entity or parent corporation, the Company agrees that a condition
      of
      such transaction will be that the successor or purchasing corporation, as the
      case may be, shall assume the obligations of the Company hereunder in writing.
      In the case of any such consolidation, merger or sale or conveyance, the Holder
      shall have the right until the Expiration Date upon payment of the Exercise
      Price in effect immediately prior to such action, to receive the kind and amount
      of shares and other securities and/or property which it would have owned or
      have
      been entitled to receive after the happening of such consolidation, merger,
      sale
      or conveyance had this Warrant been exercised immediately prior to such action,
      subject to adjustments which shall be as nearly equivalent as may be practicable
      to the adjustments provided for in this Section 3. The provisions of this
      Section 3.3 shall similarly apply to successive consolidations, mergers, sales
      or conveyances.

     

    3.4    Non-Public
      Successor.
      In case
      of any consolidation of the Company with or a merger of the Company into another
      corporation or in case of any sale or conveyance to another corporation of
      the
      property of the Company as an entirety or substantially as an entirety, upon
      any
      such consolidation, merger, sale or conveyance (i) the surviving entity is
      not a public reporting company (as defined above), or (ii) the
      consideration to be received by the holders of the Company’s Common Stock does
      not include any publicly traded equity securities in the surviving entity or
      its
      parent corporation, the Company agrees that a condition of such transaction
      will
      be that the Company shall mail to the Holder at the earliest applicable time
      (and, in any event not less than ten (10) days before any record date for
      determining the persons entitled to receive the consideration payable in such
      transaction) written notice of such record date. Such notice shall also set
      forth facts as shall indicate the effect of such action (to the extent such
      effect may be known at the date of such notice) on the Exercise Price of and
      the
      kind and amount of the Shares and other securities and property deliverable
      upon
      exercise of the Warrants. Upon the closing of the transaction referenced in
      the
      foregoing notice, this Warrant Agreement and the Warrants hereunder to the
      extent then unexercised shall terminate.

     

    3.5    Exchanges
      and Distributions With Respect to Common Stock.
      If the
      Company shall exchange for its Common Stock or distribute with respect to its
      Common Stock other securities issued by it, the Company shall give notice
      thereof to the Holder, and the Holder shall have the right thereafter (until
      the
      Expiration Date) to exercise the Warrants for the kind and amount of shares
      of
      stock and other securities retained or received by a holder of the number of
      shares of Common Stock of the Company into which the Warrants might have been
      exercised immediately prior to such exchange or distribution, subject to
      adjustment as provided hereinabove.

     

    3.6    Officer’s
      Certificate.
      Whenever the Exercise Price or the number of shares of Common Stock subject
      to
      this Warrant Agreement is adjusted, the Company shall promptly mail to the
      Holder a notice of adjustment. The notice of adjustment shall include a brief
      statement of the facts requiring the adjustment and the manner of computing
      it,
      and shall be certified by the chief financial officer of the Company. The
      determination of the adjustment shall be made by the Company in its sole
      discretion and shall be final and binding upon the Holder.

     

    4.     
      Shares
      to Be Fully Paid; Reservation of Capital Stock Issuable Upon Exercise of
      Warrants.
      The
      Company covenants and agrees that any Shares issued hereunder will,
      upon

      be fully paid and non-assessable and free from all taxes, liens and charges
      with
      respect to the issuance thereof. The Company shall at all times reserve and
      keep
      available out of its authorized but unissued capital stock, solely for the
      issuance and delivery upon the exercise of the Warrants, such number of its
      duly
      authorized shares of Common Stock as from time to time shall be issuable upon
      the exercise of the Warrants.

     

    5.     
      Fractional
      Shares.
      The
      Company shall not issue fractions of shares of Common Stock upon exercise of
      the
      Warrants or scrip in lieu thereof. If any fraction of a share of Common Stock
      would, except for the provisions of this Section 5, be issuable upon exercise
      of
      the Warrants, then the number of shares of Common Stock to be issued shall
      be
      rounded up or down to the nearest whole share.

     

    6.     
      Transfer

      A
      Holder, including the Initial Holder or any subsequent Holder, may transfer

      Prior to any such transfer, the Holder must deliver the Assignment Form in
      the
      form of Exhibit
      B
      hereto
      and provide information to the Company, in writing, regarding the proposed
      transferee sufficient for the Company to determine the eligibility of such
      transferee under this Section 6.

     

    7.     
      Securities
      Law Compliance.

     

    7.1    Investment.
      Unless
      the Shares to be issued upon exercise of the Warrants are then included in
      an
      effective registration statement filed under the Securities Act of 1933, as
      amended (the “Securities
      Act”),
      the
      Holder, by accepting this Warrant Agreement, covenants and agrees that, at
      the
      time of exercise hereof, and at the time of any proposed transfer of the
      Warrants of Shares acquired upon exercise hereof, the Holder shall deliver
      to
      the Company a written statement that the securities acquired by the Holder
      upon
      exercise hereof are for the account of the Holder or are being held by the
      Holder as trustee, investment manager, investment advisor or as any other
      fiduciary for the account of the beneficial owner or owners for investment
      and
      are not acquired with a view to, or for sale in connection with, any
      distribution thereof (or any portion thereof) and with no present intention
      (at
      any such time) of offering and distributing such securities (or any portion
      thereof), and including such other representations as may be reasonably
      requested by counsel to the Company. Further, the Holder shall comply with
      such
      provisions of applicable state securities laws as counsel to the Company or
      other counsel reasonably acceptable to the Company shall advise. 

     

    7.2    Legend.
      Unless
      the Shares issuable upon exercise of the Warrants are registered under the
      Securities Act, upon exercise of any part of the Warrants and the issuance
      of
      any of such Shares, the Company shall instruct its transfer agent to enter
      stop
      transfer orders with respect to such Shares, and all certificates representing
      the Shares issued upon exercise hereof shall bear on the face thereof
      substantially the following legend, insofar as is consistent with applicable
      law:

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

     

    “The
      shares of Common Stock represented by this Certificate have not been registered
      under the Securities Act of 1933, as amended, and may not be sold, offered
      for
      sale, assigned, transferred or otherwise disposed of unless registered pursuant
      to the provisions of that Act or an opinion of counsel to the Company is
      obtained stating that such disposition is in compliance with an available
      exemption from such registration.”

     

    7.3    No
      Registration Rights.
      The
      Holder acknowledges that it will have no demand, “piggy-back” or other rights
      for inclusion of the Shares in any registration statement which may hereafter
      be
      filed by the Company under the Securities Act.

     

    8.     
      Replacement
      of Warrant Agreement.
      Upon
      receipt of evidence reasonably satisfactory to the Company of the loss, theft,
      destruction or mutilation of this Warrant Agreement and (in the case of loss,
      theft or destruction) upon delivery of an indemnity agreement, and if requested
      by the Board of Directors, a bond in an amount reasonably satisfactory to it,
      or
      (in the case mutilation) upon surrender and cancellation hereof, the Company
      will issue in lieu thereof a new Warrant Agreement of like tenor.

     

    9.     
      Rights
      as a Warrant Holder.
      The
      Holder shall not, by virtue hereof, be entitled to any rights of a stockholder
      in the Company, either at law or equity except with respect to certificates
      representing shares of Common Stock issued upon exercise of this Warrant. The
      rights of the Holder are limited to those expressed in this Warrant Agreement
      and are not enforceable against the Company except to the extent set forth
      herein. Prior to due presentment for transfer of this Warrant Agreement, the
      Company may deem and treat the Holder as the absolute owner of this Warrant
      Agreement for purposes of any exercise hereof and for all other purposes and
      such right of the Company shall not be affected by any notice to the
      contrary.

     

    10.    Subdivision
      of Rights.

      Warrant Agreement (as well as any new Warrants issued pursuant to the provisions
      of this Section) is exchangeable upon the surrender hereof by the Holder at

      principal office of the Company for any number of new Warrants of like tenor
      and
      date representing in the aggregate the right to subscribe for and purchase
      the

      COMMON
        STOCK PURCHASE WARRANT AGREEMENT

       

      JAVELIN
        PHARMACEUTICALS, INC., a Delaware corporation (the “Company”),
        hereby grants to THE
        INVESTOR RELATIONS GROUP INC. (the
        “Initial
        Holder”),
        subject to the terms set forth in this Common Stock Purchase Warrant Agreement
        (the “Warrant
        Agreement”),
        the
        right to exercise Common Stock Purchase Warrants (the “Warrants”)
        for
        the purchase from the Company of up to 25,000
        shares
        (the “Shares”)
        of the
        Company’s Common Stock, at an exercise price of $3.00
        per
        share, subject to adjustment from time to time pursuant to Section 3 hereof
        (the
“Exercise
        Price”).
        The
        term “Common
        Stock”
means,
        unless the context otherwise requires, the Company’s Common Stock, par value
        $.001 per share, or other securities or property at the time deliverable
        upon
        the exercise of this Warrant.

       

      This
        Warrant had been originally issued to the Initial Holder by Intrac, Inc.,
        a
        Nevada corporation (“Intrac”) in consideration of the March 22, 2005 letter of
        agreement for investor relations and public relations consulting services
        between the Initial Holder and Intrac, Inc. Effective September 7, 2005,
        Intrac
        merged with and into the Company, and the Company assumed all outstanding
        warrants to purchase Intrac common stock on the same terms as the Intrac
        warrants, except exercisable for shares of the Company’s Common Stock.

       

      1.     
        Exercise.

       

      1.1    Timing
        of Exercise.
        The
        Warrants shall be exercisable at any time in whole or in part from time to
        time
        commencing as of the date hereof and expiring at 5:00 P.M., New York time,
        on
        March 21, 2010 (the “Expiration
        Date”),
        subject to earlier termination as provided herein, and may not be exercised
        thereafter.

       

      1.2    Manner
        of Exercise.
        The
        purchase rights evidenced by this Warrant Agreement shall be exercised by
        the
        Initial Holder or any person permitted by Section 6 hereof (collectively,
“the
Holder”),
        by
        surrendering this Warrant Agreement, together with the Notice of Exercise
        in

       

      
        
          
          

        

        
          
          

          
            

          

        

        
          
          

        

      

       

      the
        form
        of Exhibit
        A
        annexed
        hereto duly executed by the Holder, to the Company at the address in Section
        11
        hereof for sending of notices, accompanied by payment (in cash, by wire transfer
        or by certified or official bank check or checks) of the applicable Exercise
        Price.

       

      1.3    Net
        Issue Exercise.

       

      (a)    In
        lieu
        of making payment a monetary payment as provided in Section 1.2 hereof upon
        exercise, the Holder may elect, in its sole discretion, to receive shares
        of
        Common Stock equal to the value (as determined below) of the Warrants then
        being
        exercised by surrender of this Warrant Agreement to the Company, together
        with
        the Notice of Exercise and notice of the net issue election. Thereupon, the
        Company shall issue to the Holder the number of Shares computed using the
        following formula:

       

      X
        =
        Y(A-B) / A

       

      Where:          
        X
        = the
        number of Shares to be issued to the Holder pursuant to this Section
        1.3.

       

      Y=
        the
        number of Shares in respect of which the net issue exercise is being
        made.

       

      A=
        the
        current fair market value of one share of Common Stock.

       

      B=
        the
        Exercise Price at the time the net issue exercise is being made.

       

      (b)    For
        the
        purpose of this Section, the fair market value of the Shares shall mean with
        respect to each share of Common Stock:

       

      (i)    If
        the
        Shares are listed on any national securities exchange or quoted on the Nasdaq
        National Market, Nasdaq Small Cap Market or the OTC Bulletin Board, the average
        of the closing prices of the Shares, sold on the primary securities exchange
        or
        market on which the Shares are at the time listed or traded, for the ten
        (10)
        trading days immediately prior to the day the Notice of Exercise is received
        by
        the Company; or

       

      (ii)    If
        the
        Shares are not quoted on any national securities exchange or quoted on the
        Nasdaq National Market, Nasdaq Small Cap Market or the OTC Bulletin Board,
        the
        average of the mean between the highest bid and lowest asked price on such
        a day
        in the domestic over-the-counter market as reported by the National Quotation
        Bureau or any similar successor organization, for the thirty (30) calendar
        days
        immediately prior to the day the Notice of Exercise is received by the
        Company;

       

      (iii)    If
        there
        is no public market for the Shares, the price determined by the Board of
        Directors of the Company acting in good faith.

       

      1.4    Partial
        Exercise.
        This
        Warrant may be exercised for less than the full number of Shares available
        for
        exercise at the time the Notice of Exercise is submitted, in which case the
        number of Shares receivable upon the exercise of this Warrant as a whole,
        and
        the amount payable upon the exercise of this Warrant as a whole, shall be
        proportionately reduced. Upon any such partial exercise, the Company at its
        expense will forthwith issue to the Holder a new

       

      
        
          
          

        

        
          2

          
            

          

        

        
          
          

        

      

       

      Warrant
        Agreement of like tenor calling for Warrants to purchase the number of shares
        of
        Common Stock as to which rights have not been exercised. 

       

      2.     
        Delivery
        of Stock Certificates Upon Exercise.
        As soon
        as practicable after the exercise of any Warrants, and in any event within
        five
        (5) business days thereafter, the Company, at its expense, will cause to
        be
        issued in the name of and delivered to the Holder or other person specified
        in
        the Notice of Exercise a certificate or certificates for the number of fully
        paid and non-assessable shares of Common Stock to which the Holder shall
        be
        entitled upon such exercise, subject to compliance with Section 7 hereof.
        Any
        shares of Common Stock as to which this Warrant is exercised shall be deemed
        issued on and as of the date of such exercise, and the Holder shall thereupon
        be
        deemed to be the owner of record of such Shares.

       

      3.     
        Anti-Dilution
        Adjustments.

       

      3.1    Change
        in Capitalization.
        If the
        Company shall at any time prior to the Expiration Date subdivide its outstanding
        Common Stock, by forward stock split or otherwise, or combine its outstanding
        Common Stock (including a reverse split), or issue additional shares of its
        Common Stock in payment of a stock dividend in respect of its Common Stock,
        the
        Shares shall forthwith be proportionately increased in the case of a subdivision
        or stock dividend, or proportionately decreased in the case of a combination,
        and the Exercise Price then applicable to the Shares covered by the unexercised
        portion of the Warrants shall forthwith be proportionately decreased in the
        case
        of a subdivision or stock dividend, or proportionately increased in the case
        of
        a combination.

       

      3.2    Reclassification.
        In case
        of any reclassification, capital reorganization or change of the outstanding
        Common Stock of the Company (other than as a result of a subdivision,
        combination or stock dividend covered by Section 3.1 hereof), at any time
        prior
        to the Expiration Date, then, as a condition of such reclassification,
        reorganization or change, lawful provision shall be made, and duly executed
        documents evidencing the same from the Company or its successor shall be
        delivered to the Holder, so that the Holder shall have the right prior to
        the
        Expiration Date to purchase, at a total price not to exceed that payable
        upon
        the exercise of the unexercised portion of the Warrants, the kind and amount
        of
shares of stock and other securities and property receivable upon such
        reclassification, reorganization or change, by a holder of the number of
        shares
        of Common Stock of the Company which might have been purchased by the Holder
        immediately prior to such reclassification, reorganization or change, and
        in any
        such case appropriate provisions shall be made with respect to the rights
        and
        interest of the Holder to the end that the provisions hereof (including without
        limitation, provisions for the adjustment of the Exercise Price and of the
        number of Shares purchasable upon exercise of the Warrants) shall thereafter
        be
        applicable in relation to any shares of stock and other securities and property
        thereafter deliverable upon exercise hereof.

       

      3.3    Consolidation,
        Merger and Sale of Assets.
        In case
        of any consolidation of the Company with or a merger of the Company into
        another
        corporation or in case of any sale or conveyance and to another corporation
        of
        the property of the Company as an entirety or substantially as an entirety,
        upon
        any such consolidation, merger, sale or conveyance (i) the surviving entity
        or its parent corporation is a public reporting company under the Securities
        Exchange Act of 1934, as amended, and (ii) the consideration to be received
        by the holders of

       

      
        
          
          

        

        
          3

          
            

          

        

        
          
          

        

      

       

      the
        Company’s Common Stock includes publicly traded equity securities in the
        surviving entity or parent corporation, the Company agrees that a condition
        of
        such transaction will be that the successor or purchasing corporation, as
        the
        case may be, shall assume the obligations of the Company hereunder in writing.
        In the case of any such consolidation, merger or sale or conveyance, the
        Holder
        shall have the right until the Expiration Date upon payment of the Exercise
        Price in effect immediately prior to such action, to receive the kind and
        amount
        of shares and other securities and/or property which it would have owned
        or have
        been entitled to receive after the happening of such consolidation, merger,
        sale
        or conveyance had this Warrant been exercised immediately prior to such action,
        subject to adjustments which shall be as nearly equivalent as may be practicable
        to the adjustments provided for in this Section 3. The provisions of this
        Section 3.3 shall similarly apply to successive consolidations, mergers,
        sales
        or conveyances.

       

      3.4    Non-Public
        Successor.
        In case
        of any consolidation of the Company with or a merger of the Company into
        another
        corporation or in case of any sale or conveyance to another corporation of
        the
        property of the Company as an entirety or substantially as an entirety, upon
        any
        such consolidation, merger, sale or conveyance (i) the surviving entity is
        not a public reporting company (as defined above), or (ii) the
        consideration to be received by the holders of the Company’s Common Stock does
        not include any publicly traded equity securities in the surviving entity
        or its
        parent corporation, the Company agrees that a condition of such transaction
        will
        be that the Company shall mail to the Holder at the earliest applicable time
        (and, in any event not less than ten (10) days before any record date for
        determining the persons entitled to receive the consideration payable in
        such
        transaction) written notice of such record date. Such notice shall also set
        forth facts as shall indicate the effect of such action (to the extent such
        effect may be known at the date of such notice) on the Exercise Price of
        and the
        kind and amount of the Shares and other securities and property deliverable
        upon
        exercise of the Warrants. Upon the closing of the transaction referenced
        in the
        foregoing notice, this Warrant Agreement and the Warrants hereunder to the
        extent then unexercised shall terminate.

       

      3.5    Exchanges
        and Distributions With Respect to Common Stock.
        If the
        Company shall exchange for its Common Stock or distribute with respect to
        its
        Common Stock other securities issued by it, the Company shall give notice
        thereof to the Holder, and the Holder shall have the right thereafter (until
        the
        Expiration Date) to exercise the Warrants for the kind and amount of shares
        of
        stock and other securities retained or received by a holder of the number
        of
        shares of Common Stock of the Company into which the Warrants might have
        been
        exercised immediately prior to such exchange or distribution, subject to
        adjustment as provided hereinabove.

       

      3.6    Officer’s
        Certificate.
        Whenever the Exercise Price or the number of shares of Common Stock subject
        to
        this Warrant Agreement is adjusted, the Company shall promptly mail to the
        Holder a notice of adjustment. The notice of adjustment shall include a brief
        statement of the facts requiring the adjustment and the manner of computing
        it,
        and shall be certified by the chief financial officer of the Company. The
        determination of the adjustment shall be made by the Company in its sole
        discretion and shall be final and binding upon the Holder.

        with
        respect to the issuance thereof. The Company shall at all times reserve and

        issuance and delivery upon the exercise of the Warrants, such number of its
        duly
        authorized shares of Common Stock as from time to time shall be issuable

        The
        Company shall not issue fractions of shares of Common Stock upon exercise
        of the
        Warrants or scrip in lieu thereof. If any fraction of a share of Common Stock
        would, except for the provisions of this Section 5, be issuable upon exercise
        of
        the Warrants, then the number of shares of Common Stock to be issued shall
        be
        rounded up or down to the nearest whole share.

       

      6.

      7.1    Investment.
        Unless

        an
        effective registration statement filed under the Securities Act of 1933,
        as
        amended (the “Securities
        Act”),
        the
        Holder, by accepting this Warrant Agreement, covenants and agrees that, at
        the
        time of exercise hereof, and at the time of any proposed transfer of the
        Warrants of Shares acquired upon exercise hereof, the Holder shall deliver
        to
        the Company a written statement that the securities acquired by the Holder
        upon
        exercise hereof are for the account of the Holder or are being held by the
        Holder as trustee, investment manager, investment advisor or as any other
        fiduciary for the account of the beneficial owner or owners for investment
        and
        are not acquired with a view to, or for sale in connection with, any
        distribution thereof (or any portion thereof) and with no present intention
        (at
        any such time) of offering and distributing such securities (or any portion
        thereof), and including such other representations as may be reasonably
        requested by counsel to the Company. Further, the Holder shall comply with
        such
        provisions of applicable state securities laws as counsel to the Company
        or
        other counsel reasonably acceptable to the Company shall advise. 

       

      7.2    Legend.
        Unless
        the Shares issuable upon exercise of the Warrants are registered under the
        Securities Act, upon exercise of any part of the Warrants and the issuance
        of
        any of such Shares, the Company shall instruct its transfer agent to enter
        stop
        transfer orders with respect to such Shares, and all certificates representing
        the Shares issued upon exercise hereof shall bear on the face thereof
        substantially the following legend, insofar as is consistent with applicable
        law:

       

      
        
          
          

        

        
          5

          
            

          

        

        
          
          

        

      

       

      “The
        shares of Common Stock represented by this Certificate have not been registered
        under the Securities Act of 1933, as amended, and may not be sold, offered
        for
        sale, assigned, transferred or otherwise disposed of unless registered pursuant
        to the provisions of that Act or an opinion of counsel to the Company is
        obtained stating that such disposition is in compliance with an available
        exemption from such registration.”

       

      7.3    No
        Registration Rights.
        The
        Holder acknowledges that it will have no demand, “piggy-back” or other rights
        for inclusion of the Shares in any registration statement which may hereafter
        be
        filed by the Company under the Securities Act.

       

      8.     
        Replacement

        receipt of evidence reasonably satisfactory to the Company of the loss, theft,
        destruction or mutilation of this Warrant Agreement and (in the case of loss,
        theft or destruction) upon delivery of an indemnity agreement, and if requested
        by the Board of Directors, a bond in an amount reasonably satisfactory to
        it, or
        (in the case mutilation) upon surrender and cancellation hereof, the Company
        will issue in lieu thereof a new Warrant Agreement of like tenor.

       

      9.     
        Rights
        as a Warrant Holder.
        The
        Holder shall not, by virtue hereof, be entitled to any rights of a stockholder
        in the Company, either at law or equity except with respect to certificates
        representing shares of Common Stock issued upon exercise of this Warrant.
        The
        rights of the Holder are limited to those expressed in this Warrant Agreement
        and are not enforceable against the Company except to the extent set forth
        herein. Prior to due presentment for transfer of this Warrant Agreement,
        the
        Company may deem and treat the Holder as the absolute owner of this Warrant
        Agreement for purposes of any exercise hereof and for all other purposes
        and
        such right of the Company shall not be affected by any notice to the
        contrary.

       

      10.    Subdivision
        of Rights.

        principal office of the Company for any number of new Warrants of like tenor
        and
        date representing in the aggregate the right to subscribe for and purchase
        the
        number of shares of Common Stock of the Company that may be purchased
        hereunder.

        securities. Neither this Warrant Agreement nor any term hereof may be
        changed,

      waived,
        discharged or terminated orally, but only by an instrument in writing signed

      14.    Binding.

        Warrant Agreement shall be binding upon and inure to the benefit of the Company
