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.




3


(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.
