    CAPITAL
      GROWTH SYSTEMS, INC., a corporation organized under the laws of the State of
      Florida (the “Company”), hereby certifies that, for value received, the person
      or entity named above as Holder (the “Holder”), or assigns, is entitled, subject
      to the terms set forth below, to purchase from the Company from and after the
      Issue Date of this Warrant and at any time or from time to time before 5:00
      p.m., central time on the earlier of 30 days following the date of sending
      the
“Call Notice” as set forth below, or December 31, 2011 (the “Expiration Date”),
      up to the number of shares of fully paid and nonassessable Series A Convertible
      Preferred Stock (the “Warrant Amount”) of the Company at a per share purchase
      price equal to $1000.00 per share (the “Purchase Price”). Holder acknowledges
      that effective upon the filing of an amendment to the Articles of Incorporation
      of the Company increasing its authorized Common Stock to not less than
      50,000,000 shares (the "Amendment"), each share of Series A Convertible
      Preferred Stock shall automatically be converted into 1111.11 shares of $0.0001
      par value Company common stock (“Common Stock”) (subject to rounding as to each
      block of shares held by each holder thereof to the nearest whole share).
      Notwithstanding anything to the contrary contained herein, effective as of
      the
      filing of the Amendment, the Warrant Amount hereunder shall be automatically
      converted into the right to receive that number of shares of Common Stock equal
      to the product of 1111.11 times the number of shares of Series A Convertible
      Preferred Stock purchasable hereunder, the Purchase Price for each share of
      Common Stock shall be adjusted to $0.90 per share and all references herein
      to
      Series A Convertible Preferred Stock shall thereafter apply to the Common Stock
      into which said Series A Convertible Preferred Stock has been converted; and
      provided further in the event that the “Pipe Common Stock Price” as defined in
      the Purchase Agreement pursuant to which this Warrant has been issued is less
      than $0.90 per share, then the Purchase Price for each share of Common Stock
      shall be adjusted to the Pipe Common Stock Price.

    In
      the
      event that following the date of issuance of this Warrant, the closing price
      for
      the Company’s Common Stock is $4.00 per share or greater (as equitably adjusted
      for stock splits, reverse splits or other recapitalization or reorganization
      of
      the Company after the date hereof as provided in Section 4 below) for 20
      consecutive trading days and within 10 business days following the attainment
      of
      this trading level, the Company sends a “Call Notice” to the Holder hereof
      pursuant to the Notice provisions of this Warrant, and addressed to the Holder
      at the Holder’s last known address, and provided further that during the period
      from the date of the Call Notice through 30 days following the date of sending
      the Call Notice (such last day being the “Outside Date”), Holder has the right
      to sell the shares of Common Stock underlying this Warrant pursuant to an
      effective registration statement as filed with the Securities & Exchange
      Commission (that is not subject to a stop order or suspension—the “Registration
      Statement”), then the Holder must exercise this Warrant on or before 5:00 p.m.
      CST on the Outside Date or the rights under this Warrant shall lapse as of
      the
      end of the Outside Date; provided however if at any time from the date of
      sending of the Call Notice until the Outside Date the Holder’s right to sell
      shares of Common Stock purchased pursuant to the exercise of this Warrant
      pursuant to the terms of the Registration Statement is invalid due to either
      the
      suspension of the Registration Statement or its expiration (without immediate
      replacement by a subsequent effective registration statement), then the Call
      Notice shall be deemed null and void ab initio and this Warrant shall remain
      in
      full force and effect subject to a possible subsequent Call Notice which could
      be provided in the event the other requirements for the Call Notice to be sent
      are met.

     

    1. Exercise
      of Warrant.

     

    1.1 Number
      of Shares Issuable upon Exercise.
      From
      and after the date hereof through and including the Expiration Date, the Holder
      hereof shall be entitled to receive, upon exercise of this Warrant in whole
      in
      accordance with the terms of subsection 1.2 or upon exercise of this
      Warrant in part in accordance with subsection 1.3, shares of Series A
      Convertible Preferred Stock (or as provided in the forepart hereof, shares
      of
      Common Stock) subject to adjustment pursuant to Section 4.

     

    1.2 Full
      Exercise.
      This
      Warrant may be exercised in full by the Holder hereof by delivery of an original
      or facsimile copy of the form of subscription attached as Exhibit A hereto
      (the “Subscription Form”) duly executed by such Holder and surrender of the
      original Warrant within seven (7) days of exercise, to the Company at its
      principal office or at the office of its Warrant Agent (as provided
      hereinafter), accompanied by payment, in cash, wire transfer or by certified
      or
      official bank check payable to the order of the Company, in the amount obtained
      by multiplying the number of shares of Series A Convertible Preferred Stock
      for
      which this Warrant is then exercisable by the Purchase Price then in effect.
      

     

    1.3 Partial
      Exercise.
      This
      Warrant may be exercised in part (including a fractional share, provided that
      following the Amendment, it may only be exercised for whole shares of Common
      Stock) by surrender of this Warrant in the manner and at the place provided
      in
      subsection 1.2 except that the amount payable by the Holder on such partial
      exercise shall be the amount obtained by multiplying (a) the number of
      shares of Series A Convertible Preferred Stock designated by the Holder in
      the
      Subscription Form (or Common Stock following the conversion of Series A
      Convertible Preferred Stock to Common Stock) by (b) the Purchase Price then
      in effect. On any such partial exercise, the Company, at its expense, will
      forthwith issue and deliver to or upon the order of the Holder hereof a new
      Warrant of like tenor, in the name of the Holder hereof or as such Holder (upon
      payment by such Holder of any applicable transfer taxes) may request, the number
      of shares of Series A Convertible Preferred Stock (or Common Stock following
      the
      conversion of the Series A Convertible Preferred Stock to Common Stock) for
      which such Warrant may still be exercised.

     

    
      
        
        

      

      
        2

        
          

        

      

      
        
        

      

    

    1.4 Fair
      Market Value.
      Fair
      Market Value of a share of Series A Convertible Preferred Stock as of a
      particular date (the “Determination Date”) shall mean: 

     

    (a) If
      the
      Company’s Common Stock is traded on an exchange or is quoted on the National
      Association of Securities Dealers, Inc. Automated Quotation (“NASDAQ”) National
      Market System, the NASDAQ SmallCap Market or the American Stock Exchange, Inc.,
      then an amount equal to the product of the closing or last sale price,
      respectively, reported for the last business day immediately preceding the
      Determination Date for a share of such Common Stock, multiplied by the
      conversion rate then in place for the Series A Convertible Preferred Stock,
      as
      applicable, or following the Amendment, it shall simply be the aforesaid price
      for the Company’s Common Stock. 

     

    (b) If
      the
      Company’s Common Stock is not traded on an exchange or on the NASDAQ National
      Market System, the NASDAQ SmallCap Market or the American Stock Exchange, Inc.,
      but is traded in the over-the-counter market, then the mean of the closing
      bid
      and asked prices reported for the last business day immediately preceding the
      Determination Date for a share of such Common Stock, multiplied by the
      conversion ratio then in place for the Series A Convertible Preferred Stock,
      as
      applicable, or following the Amendment, it shall simply be the aforesaid price
      for the Company’s Common Stock.

     

    (c) Except
      as
      provided in clause (d) below, if the Company’s Common Stock is not publicly
      traded, then as the Holder and the Company agree or in the absence of agreement
      by arbitration in accordance with the rules then standing of the American
      Arbitration Association, before a single arbitrator to be chosen from a panel
      of
      persons qualified by education and training to pass on the matter to be
      decided.

     

    (d) If
      the
      Determination Date is the date of a liquidation, dissolution or winding up,
      or
      any event deemed to be a liquidation, dissolution or winding up pursuant to
      the
      Company’s charter, then all amounts to be payable per share to holders of the
      Series A Convertible Preferred Stock pursuant to the charter in the event of
      such liquidation, dissolution or winding up, plus all other amounts to be
      payable per share in respect of the Series A Convertible Preferred Stock in
      liquidation under the charter, assuming for the purposes of this clause
      (d) that all of the shares of Series A Convertible Preferred Stock then
      issuable upon exercise of all of the Warrants are outstanding at the
      Determination Date.

     

    
      
        
        

      

      
        3

        
          

        

      

      
        
        

      

    

    1.5 Company
      Acknowledgment.
      The
      Company will, at the time of the exercise of the Warrant, upon the request
      of
      the Holder hereof acknowledge in writing its continuing obligation to afford
      to
      such Holder any rights to which such Holder shall continue to be entitled after
      such exercise in accordance with the provisions of this Warrant. If the Holder
      shall fail to make any such request, such failure shall not affect the
      continuing obligation of the Company to afford to such Holder any such rights.
      

     

    1.6 Trustee
      for Warrant Holders.
      In the
      event that a bank or trust company shall have been appointed as trustee for
      the
      Holders of the Warrants pursuant to Subsection 3.2, such bank or trust
      company shall have all the powers and duties of a warrant agent (as hereinafter
      described) and shall accept, in its own name for the account of the Company
      or
      such successor person as may be entitled thereto, all amounts otherwise payable
      to the Company or such successor, as the case may be, on exercise of this
      Warrant pursuant to this Section 1. 

     

    2.1 Delivery
      of Stock Certificates, etc. on Exercise.
      The
      Company agrees that the shares of Series A Convertible Preferred Stock (or
      following the Amendment the corresponding shares of Common Stock) purchased
      upon
      exercise of this Warrant shall be deemed to be issued to the Holder hereof
      as
      the record owner of such shares as of the close of business on the date on
      which
      this Warrant shall have been surrendered and payment made for such shares as
      aforesaid. As soon as practicable after the exercise of this Warrant in full
      or
      in part, and in any event within seven (7) days thereafter, the Company at
      its
      expense (including the payment by it of any applicable issue taxes) will cause
      to be issued in the name of and delivered to the Holder hereof, or as such
      Holder (upon payment by such Holder of any applicable transfer taxes) may direct
      in compliance with applicable securities laws, a certificate or certificates
      for
      the number of duly and validly issued, fully paid and nonassessable shares
      of
      Series A Convertible Preferred Stock (or following the Amendment, shares of
      Common Stock) to which such Holder shall be entitled on such exercise, plus,
      in
      lieu of any fractional share to which such Holder would otherwise be entitled,
      cash equal to such fraction multiplied by the then Fair Market Value of one
      full
      share, together with any other stock or other securities and property (including
      cash, where applicable) to which such Holder is entitled upon such exercise
      pursuant to Section 1 or otherwise. 

     

    3. Adjustment
      for Reorganization, Consolidation, Merger, etc.

     

    3.1. Reorganization,
      Consolidation, Merger, etc.
      In case
      at any time or from time to time, the Company shall (a) effect a
      reorganization, (b) consolidate with or merge into any other person or
      (c) transfer all or substantially all of its properties or assets to any
      other person under any plan or arrangement contemplating the dissolution of
      the
      Company, then, in each such case, as a condition to the consummation of such
      a
      transaction, proper and adequate provision shall be made by the Company whereby
      the Holder of this Warrant, on the exercise hereof as provided in
      Section 1, at any time after the consummation of such reorganization,
      consolidation or merger or the effective date of such dissolution, as the case
      may be, shall receive, in lieu of the Series A Convertible Preferred Stock
      (or
      Common Stock following the Amendment) issuable on such exercise prior to such
      consummation or such effective date, the stock and other securities and property
      (including cash) to which such Holder would have been entitled upon such
      consummation or in connection with such dissolution, as the case may be, if
      such
      Holder had so exercised this Warrant, immediately prior thereto, all subject
      to
      further adjustment thereafter as provided in Section 4.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    3.2. Dissolution.
      In the
      event of any dissolution of the Company following the transfer of all or
      substantially all of its properties or assets, the Company, prior to such
      dissolution, shall at its expense deliver or cause to be delivered the stock
      and
      other securities and property (including cash, where applicable) receivable
      by
      the Holders of the Warrants after the effective date of such dissolution
      pursuant to this Section 3 to a bank or trust company selected by the
      Company, as trustee for the Holder or Holders of the Warrants. 

     

    3.3. Continuation
      of Terms.
      Upon
      any reorganization, consolidation, merger or transfer (and any dissolution
      following any transfer) referred to in this Section 3, this Warrant shall
      continue in full force and effect and the terms hereof shall be applicable
      to
      the shares of stock and other securities and property receivable on the exercise
      of this Warrant after the consummation of such reorganization, consolidation
      or
      merger or the effective date of dissolution following any such transfer, as
      the
      case may be, and shall be binding upon the issuer of any such stock or other
      securities, including, in the case of any such transfer, the person acquiring
      all or substantially all of the properties or assets of the Company, whether
      or
      not such person shall have expressly assumed the terms of this Warrant as
      provided in Section 4. In the event this Warrant does not continue in full
      force and effect after the consummation of the transaction described in this
      Section 3, then only in such event will the Company’s securities and
      property (including cash, where applicable) receivable by the Holders of the
      Warrants be delivered to the Trustee as contemplated by
      Section 3.2.

     

    4. Extraordinary
      Events Regarding Capital Stock.
      In the
      event that the Company shall (a) issue additional shares of its capital
      stock as a dividend or other distribution on outstanding capital stock,
      (b) subdivide its outstanding shares of capital stock or (c) combine
      its outstanding shares of capital stock into a smaller number of shares of
      its
      capital stock, then, in each such event, the Purchase Price shall,
      simultaneously with the happening of such event, be adjusted by multiplying
      the
      then Purchase Price by a fraction, the numerator of which shall be the number
      of
      shares of capital stock outstanding immediately prior to such event and the
      denominator of which shall be the number of shares of capital stock outstanding
      immediately after such event, and the product so obtained shall thereafter
      be
      the Purchase Price then in effect. The Purchase Price, as so adjusted, shall
      be
      readjusted in the same manner upon the happening of any successive event or
      events described herein in this Section 4. The number of shares of capital
      stock that the Holder of this Warrant shall thereafter, on the exercise hereof
      as provided in Section 1, be entitled to receive shall be increased to a
      number determined by multiplying the number of shares of capital stock that
      would otherwise (but for the provisions of this Section 4) be issuable on
      such exercise by a fraction of which (a) the numerator is the Purchase
      Price that would otherwise (but for the provisions of this Section 4) be in
      effect, and (b) the denominator is the Purchase Price in effect on the date
      of such exercise.

     

    5. Certificate
      as to Adjustments.
      In each
      case of any adjustment or readjustment in the shares of Series A Convertible
      Preferred Stock (or following the amendment the corresponding shares of Common
      Stock) issuable on the exercise of the Warrants, the Company at its expense
      will
      promptly cause its Chief Financial Officer or other appropriate designee to
      compute such adjustment or readjustment in accordance with the terms of the
      Warrant and prepare a certificate setting forth such adjustment or readjustment
      and showing in detail the facts upon which such adjustment or readjustment
      is
      based, including a statement of (a) the consideration received or
      receivable by the Company for any additional shares of Series A Convertible
      Preferred Stock issued or sold or deemed to have been issued or sold,
      (b) the number of shares of Series A Convertible Preferred Stock
      outstanding or deemed to be outstanding and (c) the Purchase Price and the
      number of shares of Series A Convertible Preferred Stock to be received upon
      exercise of this Warrant, in effect immediately prior to such adjustment or
      readjustment and as adjusted or readjusted as provided in this Warrant (subject
      to adjustment as to the aforesaid subparagraphs for Common Stock following
      the
      Amendment). The Company will forthwith mail a copy of each such certificate
      to
      the Holder of the Warrant and any Warrant Agent of the Company (appointed
      pursuant to Section 9 hereof).

    6. Reservation
      of Stock, etc. Issuable on Exercise of Warrant; Financial
      Statements.
      From
      and after the Issue Date of this Warrant, the Company will at all times reserve
      and keep available, solely for issuance and delivery on the exercise of the
      Warrants, all shares of Series A Convertible Preferred Stock (or following
      the
      Amendment, all shares of Common Stock) from time to time issuable on the
      exercise of the Warrant. 

     

    7. Assignment;
      Exchange of Warrant.
      Subject
      to compliance with applicable securities laws, this Warrant, and the rights
      evidenced hereby, may be transferred by any registered holder hereof (a
“Transferor”) with respect to any or all of the Shares. On the surrender for
      exchange of this Warrant, with the Transferor’s endorsement in the form of
      Exhibit B attached hereto (the “Transferor Endorsement Form”) and together
      with evidence reasonably satisfactory to the Company demonstrating compliance
      with applicable securities laws, the Company at its expense, but with payment
      by
      the Transferor of any applicable transfer taxes) will issue and deliver to
      or on
      the order of the Transferor thereof a new Warrant or Warrants of like tenor,
      in
      the name of the Transferor and/or the transferee(s) specified in such Transferor
      Endorsement Form (each a “Transferee”), calling in the aggregate on the face or
      faces thereof for the number of shares of Series A Convertible Preferred Stock
      (or following the Amendment, the shares of Common Stock) called for on the
      face
      or faces of the Warrant so surrendered by the Transferor.

     

    8. Replacement
      of Warrant.
      On
      receipt of evidence reasonably satisfactory to the Company of the loss, theft,
      destruction or mutilation of this Warrant and, in the case of any such loss,
      theft or destruction of this Warrant, on delivery of an indemnity agreement
      or
      security reasonably satisfactory in form and amount to the Company or, in the
      case of any such mutilation, on surrender and cancellation of this Warrant,
      the
      Company at its expense will execute and deliver, in lieu thereof, a new Warrant
      of like tenor.

     

    9. Warrant
      Agent.
      The
      Company may, by written notice to the each Holder of the Warrant, appoint an
      agent for the purpose of issuing Series A Convertible Preferred Stock (or
      following the Amendment, shares of Common Stock) on the exercise of this Warrant
      pursuant to Section 1, exchanging this Warrant pursuant to Section 7,
      and replacing this Warrant pursuant to Section 8, or any of the foregoing,
      and thereafter any such issuance, exchange or replacement, as the case may
      be,
      shall be made at such office by such agent. 

     

    10. Transfer
      on the Company’s Books.

    Warrant
      No. _____

    

    Issue
      Date: September 14, 2006

    

    

    WARRANT
      TO PURCHASE COMMON STOCK OF

    

    CAPITAL
      GROWTH SYSTEMS, INC.

    (a
      Florida corporation)

    

    This
      is
      to certify that David Beamish, or his, her or its permitted assigns (“Holder”),
      is entitled to purchase, subject to the provisions of this Warrant, from Capital
      Growth Systems, Inc., its successors and assigns (the “Company”), at any time on
      or after the Issue Date and for a period of five (5) years after the Issue
      Date
      (the “Exercise Period”), up to 150,000 shares of Common Stock (the “Warrant
      Shares”), for an exercise price equal to $.70 per share of Common Stock to be
      issued hereunder.

    

    The
      number of shares of Common Stock to be received upon the exercise of this
      Warrant (the
      “Exercisable Shares”) and the exercise price to be paid for a share of Common
      Stock (the “Exercisable Price”)
      may be
      adjusted from time to time as herein set forth

    

    1.  Method
      of Exercise.
      Subject
      to the other provisions of this Warrant, this Warrant may only be exercised
      in
      whole or in part during the Exercise Period by (i) payment of the Exercise
      Price
      by either (A) cash or a certified or bank check, payable to the order of the
      Company or (B) a written notice to the Company that Holder is exercising this
      Warrant (or a portion thereof) by authorizing the Company to withhold from
      issuance a number of shares of Warrant Shares issuable upon exercise of this
      Warrant which when multiplied by the Market Price of the Warrant Shares is
      equal
      to the aggregate Exercise Price (and such withheld shares shall no longer be
      issuable under this Warrant), and (ii) presentation and surrender of this
      Warrant to the Company with the exercise notice substantially in the form
      attached hereto as Exhibit A
      duly
      executed (the “Exercise Notice”). Upon receipt by the Company of this Warrant
      and the Exercise Notice in proper form for exercise, the Holder shall be deemed
      to be the Holder of record of the shares of Common Stock issuable upon such
      exercise, notwithstanding that the stock transfer books of the Company shall
      then be closed or that certificates representing such shares of Common Stock
      shall not then be actually delivered to the Holder. The Company shall use its
      best efforts to issue the proper stock certificate within five (5) business
      days
      of receiving all required documentation. Such stock certificate shall bear
      such
      legends as the Company may deem necessary or appropriate.

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    2.  Payment
      of Taxes.
      The
      Company shall pay all expenses in connection with the issue or delivery of
      this
      Warrant, other than any tax or charge imposed by law upon Holder, in which
      case
      such taxes or charges shall be paid by Holder.

     

    

    3.  Fractional
      Shares.
      No
      fractional shares or scrip representing fractional shares shall be issued upon
      the exercise of this Warrant. With respect to any fraction of a share called
      for
      upon exercise hereof, the Company shall pay to the Holder an amount in cash
      equal to such fraction multiplied by the current Market Price of a full
      share.

     

    4.  Exchange,
      Assignment or Loss of Warrant.

     

    (a)  Exchange.
      This
      Warrant is exchangeable, without expense, at the option of the Holder, upon
      presentation and surrender hereof to the Company for other Warrants in identical
      form of different denominations entitling the Holder thereof to purchase in
      the
      aggregate the same number of shares of Common Stock purchasable
      hereunder.

     

    (b)  Assignment.
      This
      Warrant may only be assigned or transferred by the Holder in accordance with
      the
      terms of this Warrant and upon the written consent of the Company, which shall
      not be unreasonably withheld; provided, however, no Holder shall assign or
      transfer this Warrant (or any portion hereof) to any Person that competes in
      whole or in part with the Company. Any assignment shall be made by surrender
      of
      this Warrant to the Company with the assignment form substantially in the form
      attached hereto as Exhibit B
      duly
      executed (the “Assignment Form”). The Company shall, within five (5) business
      days of receipt of the Warrant and Assignment Form, either (i) consent to such
      assignment and execute and deliver a new Warrant in identical form in the name
      of the assignee named in such instrument of assignment and this Warrant shall
      promptly be canceled, or (ii) notify the Holder that the Company is withholding
      its consent to such assignment. This Warrant may be divided or may be combined
      with other Warrants which carry the same rights upon presentation hereof at
      the
      office of the Company together with a written notice specifying the names and
      the denominations in which new Warrants are to be issued and signed by the
      Holder hereof. The term “Warrant” as used herein includes any Warrants issued in
      substitution for or replacement of this Warrant or into which this Warrant
      may
      be divided or exchanged.

     

    (c)  Loss.
      Upon
      receipt by the Company of evidence satisfactory to it of the loss, theft,
      destruction, or mutilation of this Warrant, and (in the case of loss, theft
      or
      destruction) of reasonably satisfactory indemnification, and upon surrender
      and
      cancellation of this Warrant if mutilated, the Company will execute and will
      deliver a new Warrant in identical form. Any such new Warrant executed and
      delivered shall constitute an additional contractual obligation on the part
      of
      the Company, whether or not this Warrant so lost, stolen, destroyed or mutilated
      shall be at any time enforceable by anyone.

    5.  Rights
      of the Holder.
      The
      Holder, by virtue hereof, shall not be entitled to any rights of a shareholder
      in the Company, either at law or in equity, and the rights of the Holder are
      limited to those expressed in this Warrant.

     

    6.  Anti-Dilution
      Adjustments.
      In
      order to prevent dilution of the exercise rights granted hereunder, the terms
      of
      this Warrant will be subject to adjustment from time to time pursuant to this
      Section 6.

     

    (a)  Adjustments
      for Other Dividends and Distributions.
      In the
      event the Company at any time prior to the expiration of this Warrant makes
      or
      issues, or fixes a record date for the determination of holders of Common Stock
      entitled to receive, a dividend or other distribution payable in securities
      of
      the Company other than shares of Common Stock, then and in each such event
      provision shall be made so that the Holder shall receive upon exercise hereof,
      in addition to the number of shares of Common Stock receivable thereupon, the
      amount of securities of the Company which the Holder would have received had
      this Warrant been exercised for Common Stock on the date of such event and
      had
      the Holder thereafter, during the period from the date of such event to and
      including the exercise date, retained such securities receivable by the Holder
      as aforesaid during such period, subject to all other adjustments called for
      during such period under this Section 6 with respect to the rights of the Holder
      of this Warrant.

     

    (b)  Subdivision
      or Combination of Common Stock.
      If
      the
      Company at any time subdivides (by any stock split, stock dividend,
      recapitalization or otherwise) one or more classes of its outstanding shares
      of
      Common Stock into a greater number of shares, then
      simultaneously with the happening of such event, (i) the Exercise Price shall,
      be adjusted by multiplying the then Exercise Price by a fraction, the numerator
      of which shall be the number of shares of Common Stock outstanding immediately
      prior to such event and the denominator of which shall be the number of shares
      of Common Stock outstanding immediately after such event, and the product so
      obtained shall thereafter be the Exercise Price then in effect, and (ii) the
      number of
      shares
      of Common Stock for which this Warrant is exercisable shall be
      proportionately increased.
      If
      the
      Company
      at any time combines (by reverse stock split or otherwise) one or more classes
      of its outstanding shares of Common Stock into a smaller number of
      shares,
      then
      simultaneously with the with the happening of such event, the Exercise Price
      and the
      number of shares of Common Stock for which this Warrant is exercisable shall
      immediately be proportionately decreased.

     

    (c)  Subsequent
      Adjustments.
      The
      Exercise Price and number of Exercisable Shares, as so adjusted pursuant to
      this
      Section 6, shall be readjusted in the same manner upon the happening of any
      successive event or events described in this Section 6.

     

    

    (d)  Reorganization,
      Reclassification, Consolidation, Merger or Sale.
      Any
      capital reorganization, reclassification, consolidation, merger or sale of
      all
      or substantially all of the Company’s assets to another Person which is effected
      in such a way that holders of Common Stock are entitled to receive (either
      directly or upon subsequent liquidation) cash, stock, securities or assets
      with
      respect to or in exchange for Common Stock is referred to herein as an “Organic
      Change”. Prior to the consummation of any Organic Change, the Company shall
      provide Holder with notice of such Organic Change, such notice to be delivered
      at least thirty (30) days prior to the consummation of the Organic Change.
      The
      Holder shall have a period of thirty (30) days to exercise this Warrant (which
      exercise may be conditioned upon the consummation of the Organic Change), and
      upon consummation of the Organic Change, this Warrant and any unexercised
      Warrant Shares shall automatically terminate. In the event the Organic Change
      is
      not consummated, this Warrant shall remain in full force and
      effect.

    (e)  Certain
      Events.
      If any
      event occurs of the type contemplated by the provisions of this Section 6
      but not expressly provided for by such provisions, then the Company’s board of
      directors and the Company will make an appropriate adjustment in the Exercise
      Price so as to protect the rights of the Holder hereunder.
