      issue thereof. The Company further warrants and agrees that during the period
      within which the rights represented by this Warrant may be exercised, the

      Register, upon surrender of this Warrant with the Form of Assignment attached

    5.  Exercise
      of Warrants.

     

    a.  Upon
      surrender of this Warrant with the Form of Election to Purchase attached hereto
      duly completed and signed to the Company, at its address set forth in Section
      12, and upon payment and delivery of the Exercise Price per Warrant Share
      multiplied by the number of Warrant Shares that the Warrant Holder intends
      to
      purchase hereunder, in lawful money of the United States of America, in cash
      or
      by certified or official bank check or checks, to the Company, all as specified
      by the Warrant Holder in the Form of Election to Purchase, the Company shall
      promptly (but in no event later than 7 business days after the Date of Exercise
      (as defined herein)) issue or cause to be issued and cause to be delivered
      to or
      upon the written order of the Warrant Holder and in such name or names as the
      Warrant Holder may designate (subject to the restrictions on transfer described
      in the legend set forth on the face of this Warrant), a certificate for the
      Warrant Shares issuable upon such exercise, with such restrictive legend as
      required by the 1933 Act. Any person so designated by the Warrant Holder to
      receive Warrant Shares shall be deemed to have become holder of record of such
      Warrant Shares as of the Date of Exercise of this Warrant.

     

    b.  A
“Date
      of Exercise” means the date on which the Company shall have received (i) this
      Warrant (or any New Warrant, as applicable), with the Form of Election to
      Purchase attached hereto (or attached to such New Warrant) appropriately
      completed and duly signed, and (ii) payment of the Exercise Price for the number
      of Warrant Shares so indicated by the Warrant Holder to be
      purchased.

     

    c.  This
      Warrant shall be exercisable at any time and from time to time for such number
      of Warrant Shares as is indicated in the attached Form of Election To Purchase.
      If less than all of the Warrant Shares which may be purchased under this Warrant
      are exercised at any time, the Company shall issue or cause to be issued, at
      its
      expense, a New Warrant evidencing the right to purchase the remaining number
      of
      Warrant Shares for which no exercise has been evidenced by this
      Warrant.

     

    d.  
      (i) Notwithstanding
      anything contained herein to the contrary but subject to Section 6, the holder
      of this Warrant may, should a registration statement pursuant to the
      Registration Agreement not be made effective within 120 days post Closing,
      exercise this Warrant in whole or in part and, in lieu of making the cash
      payment otherwise contemplated to be made to the Company upon such exercise
      in
      payment of the Aggregate Exercise Price, elect instead to receive upon such
      exercise the “Net
      Number”
of
      shares of Common Stock determined according to the following formula (a
“Cashless
      Exercise”):

    Net
      Number = (A x (B - C))/B

     

    (ii)    For
      purposes of the foregoing formula:

     

    A=
      the
      total number shares with respect to which this Warrant is then being
      exercised.

     

    B=
      the
      last reported sale price (as reported by Bloomberg) of the Common Stock on
      the
      trading day immediately preceding the date of the Exercise Notice.

     

    C=
      the
      Warrant Exercise Price then in effect at the time of such exercise.

     

    e.  The
      holder of this Warrant agrees not to elect a Cashless Exercise for a period
      of
      twelve (12) months. The holder of this Warrant also agrees not to elect a
      Cashless Exercise so long as there is an effective registration statement for
      the Warrant Shares.

     

    f.  Provided
      that the Warrant Shares are Registrable Securities (as defined in the
      Registration Rights Agreement) and are registered pursuant to an effective
      registration statement, at any time commencing on the date hereof if the
      Company’s volume weighted average share price over a thirty (30) day period (“30
      Day VWAP”) exceeds $1.50 per share, the Warrant Holder shall be forced to
      exercise this Warrant within thirty (30) calendar days from the date the 30
      Day
      VWAP exceeds $1.50 per share (“Forced Exercise Period”). Any portion of this
      Warrant not exercise during the Forced Exercise Period shall terminate upon
      at
      the end of such period. This clause is also subject to a volume restriction
      of
      approximately 25% of the daily average volume. The Company can not force the
      investor to exercise into more than 4.9% clause below. 

     

    6.  Maximum
      Exercise.
      The
      Warrant Holder shall not be entitled to exercise this Warrant
      on a Date of Exercise in connection with that number of shares of Common Stock
      which would be in excess of the sum of (i) the number of shares of Common Stock
      beneficially owned by the Warrant Holder and its affiliates on an exercise
      date,
      and (ii) the number of shares of Common Stock issuable upon the exercise of
      this
      Warrant with respect to which the determination of this limitation is being
      made
      on an exercise date, which would result in beneficial ownership by the Warrant
      Holder and its affiliates of more than 4.9% of the outstanding shares of Common
      Stock on such date. This Section 6 may be waived or amended only with the
      consent of the Holder and the consent of holders of a majority of the shares
      of
      outstanding Common Stock of the Company who are not Affiliates. For the purposes
      of the immediately preceding sentence, the term “Affiliate” shall mean any
      person: (a) that directly, or indirectly through one or more intermediaries,
      controls, or is controlled by, or is under common control with, the Company;
      or
      (b) who beneficially owns (i) any shares of the Company’s Series A Convertible
      Preferred Stock, (ii) the Company’s Common Stock Purchase Warrant “B” dated
      March 21, 2008, or (iii) this Warrant. For the purposes of the immediately
      preceding sentence, beneficial ownership shall be determined in accordance
      with
      Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
      13d-3 thereunder.

    7.     
        Adjustment
      of Exercise Price and Number of Shares.
      The
      character of the shares of stock or other securities at the time issuable upon
      exercise of this Warrant and the Exercise Price therefore, are subject to
      adjustment upon the occurrence of the following events, and all such adjustments
      shall be cumulative:

     

    a.  Adjustment
      for Stock Splits, Stock Dividends, Recapitalizations, Etc.
      The
      Exercise Price of this Warrant and the number of shares of Common Stock or
      other
      securities at the time issuable upon exercise of this Warrant shall be
      appropriately adjusted to reflect any stock dividend, stock split, combination
      of shares, reclassification, recapitalization or other similar event affecting
      the number of outstanding shares of stock or securities.

     

    b.  Adjustment
      for Reorganization, Consolidation, Merger, Etc.
      In case
      of any consolidation or merger of the Company with or into any other
      corporation, entity or person, or any other corporate reorganization, in which
      the Company shall not be the continuing or surviving entity of such
      consolidation, merger or reorganization (any such transaction being hereinafter
      referred to as a "Reorganization"),
      then,
      in each case, the holder of this Warrant, on exercise hereof at any time after
      the consummation or effective date of such Reorganization (the "Effective
      Date"),
      shall
      receive, in lieu of the shares of stock or other securities at any time issuable
      upon the exercise of the Warrant issuable on such exercise prior to the
      Effective Date, the stock and other securities and property (including cash)
      to
      which such holder would have been entitled upon the Effective Date if such
      holder had exercised this Warrant immediately prior thereto (all subject to
      further adjustment as provided in this Warrant).

     

    c.  Certificate
      as to Adjustments.
      In case
      of any adjustment or readjustment in the price or kind of securities issuable
      on
      the exercise of this Warrant, the Company will promptly give written notice
      thereof to the holder of this Warrant in the form of a certificate, certified
      and confirmed by the Board of Directors of the Company, setting forth such
      adjustment or readjustment and showing in reasonable detail the facts upon
      which
      such adjustment or readjustment is based.

     

    d.  The
      Company fails to meet certain earnings per share
      projections.
      In the
      event the Company earns between $0.0670 and $0.0335 (50% Decline) per share
      (where such earnings in this paragraph shall always be defined as earnings
      on a
      pre tax fully diluted basis (including dilution from any options, warrants
      and
      convertible securities) as reported for the audited sixth months ended June
      30,
      2008 from continuing operations before any non-cash items the then current
      Exercise Price to the Investor at the time the audited numbers are reported
      to
      the SEC shall be decrease proportionately by 0% if the pre tax earnings (for
      first six months ended June 30, 2008) are $0.0670 per share or greater and
      by
      50% if the pre tax earnings (for first six months ended June 30, 2008) are
      $0.0335 per share (50% decrease). For example if the earnings are $0.0536 per
      share or less (20% Decline) then the then current Exercise Price to the investor
      shall be reduced by 20%. Such adjustment shall be made automatically within
      five
      business days of the audited numbers being reported to the SEC.

      to the Investor at the time the audited numbers are reported to the SEC shall
      be
      decrease proportionately by 0% if the pre tax earnings are $0.1559 per share
      or
      greater and by 50% if the pre tax earnings are $0.0780 per share (50% decrease).
      For example if the earnings are $ 0.1247 per share or less (20% Decline) then
      the then current Exercise Price to the investor shall be reduced by 20%. Such
      adjustment shall be made automatically within five business days of the audited
      numbers being reported to the SEC.

     

    f.  The
      Company sells, grants or issues any shares, options, warrants, or any instrument
      convertible into shares or equity in any form below the exercise price per
      share
      of the warrant.
      In the
      event the Company sells, grants or issues any shares, options, warrants, or
      any
      instrument convertible into shares or equity in any form below the current
      exercise price per share of the warrant, then the current exercise price per
      share for the warrant shall be adjusted to a price determined by multiplying
      such exercise price by a fraction, the numerator of which shall be the number
      of
      shares of Common Stock Outstanding (defined below) immediately prior to such
      issuance plus the number of shares of Common Stock that the aggregate
      consideration received by the Company for such issuance would purchase at such
      exercise price; and the denominator of which shall be the number of shares
      of
      Common Stock Outstanding (as defined below) immediately prior to such issuance
      plus the number of shares issued at such issuance. For purposes of this
Section
      7(f),
      the
      term “Common Stock Outstanding” shall mean and include the following: (1)
      outstanding Common Stock, (2) Common Stock issuable upon conversion of
      outstanding Preferred Stock, (3) Common Stock issuable upon exercise of
      outstanding warrants. Shares described in (1) through (4) above shall be
      included whether vested or unvested, whether contingent or non-contingent and
      whether exercisable or not yet exercisable.

     

    8.  Fractional
      Shares.
      The
      Company shall not be required to issue or cause to be issued fractional Warrant
      Shares on the exercise of this Warrant. The number of full Warrant Shares that
      shall be issuable upon the exercise of this Warrant shall be computed on the
      basis of the aggregate number of Warrants Shares purchasable on exercise of
      this
      Warrant so presented. If any fraction of a Warrant Share would, except for
      the
      provisions of this Section 8, be issuable on the exercise of this Warrant,
      the
      Company shall, at its option, (i) pay an amount in cash equal to the Exercise
      Price multiplied by such fraction or (ii) round the number of Warrant Shares
      issuable, up to the next whole number.

     

    9.  Sale
      or Merger of the Company.
      Upon
      a
      Change in Control, the restriction contained in Section 6 shall immediately
      be
      released and the Warrant Holder will have the right to exercise this Warrant
      concurrently with such Change in Control event. For purposes of this Warrant,
      the term “Change in Control” shall mean a consolidation or merger of the Company
      with or into another company or entity in which the Company is not the surviving
      entity or the sale of all or substantially all of the assets of the Company
      to
      another company or entity not controlled by the then existing stockholders
      of
      the Company in a transaction or series of transactions.

              Exercise
                of Warrants.

            

    

     

    a. Upon
      surrender of this Warrant with the Form of Election to Purchase attached hereto
      duly completed and signed to the Company, at its address set forth in Section
      12, and upon payment and delivery of the Exercise Price per Warrant Share
      multiplied by the number of Warrant Shares that the Warrant Holder intends
      to
      purchase hereunder, in lawful money of the United States of America, in cash
      or
      by certified or official bank check or checks, to the Company, all as specified
      by the Warrant Holder in the Form of Election to Purchase, the Company shall
      promptly (but in no event later than 7 business days after the Date of Exercise
      (as defined herein)) issue or cause to be issued and cause to be delivered
      to or
      upon the written order of the Warrant Holder and in such name or names as the
      Warrant Holder may designate (subject to the restrictions on transfer described
      in the legend set forth on the face of this Warrant), a certificate for the
      Warrant Shares issuable upon such exercise, with such restrictive legend as
      required by the 1933 Act. Any person so designated by the Warrant Holder to
      receive Warrant Shares shall be deemed to have become holder of record of such
      Warrant Shares as of the Date of Exercise of this Warrant.

     

    b. A
“Date
      of Exercise” means the date on which the Company shall have received (i) this
      Warrant (or any New Warrant, as applicable), with the Form of Election to
      Purchase attached hereto (or attached to such New Warrant) appropriately
      completed and duly signed, and (ii) payment of the Exercise Price for the number
      of Warrant Shares so indicated by the Warrant Holder to be
      purchased.

     

    c. This
      Warrant shall be exercisable at any time and from time to time for such number
      of Warrant Shares as is indicated in the attached Form of Election To Purchase.
      If less than all of the Warrant Shares which may be purchased under this Warrant
      are exercised at any time, the Company shall issue or cause to be issued, at
      its
      expense, a New Warrant evidencing the right to purchase the remaining number
      of
      Warrant Shares for which no exercise has been evidenced by this
      Warrant.

     

    d. 
      (i) Notwithstanding
      anything contained herein to the contrary but subject to Section 6, the holder
      of this Warrant may, should a registration statement pursuant to the
      Registration Agreement not be made effective within 120 days post Closing,
      exercise this Warrant in whole or in part and, in lieu of making the cash
      payment otherwise contemplated to be made to the Company upon such exercise
      in
      payment of the Aggregate Exercise Price, elect instead to receive upon such
      exercise the “Net
      Number”
of
      shares of Common Stock determined according to the following formula (a
“Cashless
      Exercise”):

    Net
      Number = (A x (B - C))/B

     

    (ii)   For
      purposes of the foregoing formula:

     

    A=
      the
      total number shares with respect to which this Warrant is then being
      exercised.

     

    B=
      the
      last reported sale price (as reported by Bloomberg) of the Common Stock on
      the
      trading day immediately preceding the date of the Exercise Notice.

     

    C=
      the
      Warrant Exercise Price then in effect at the time of such exercise.

     

    e. The
      holder of this Warrant agrees not to elect a Cashless Exercise for a period
      of
      twelve (12) months. The holder of this Warrant also agrees not to elect a
      Cashless Exercise so long as there is an effective registration statement for
      the Warrant Shares.

     

    f. Provided
      that the Warrant Shares are Registrable Securities (as defined in the
      Registration Rights Agreement) and are registered pursuant to an effective
      registration statement, at any time commencing on the date hereof if the
      Company’s volume weighted average share price over a thirty (30) day period (“30
      Day VWAP”) exceeds $2.00 per share, the Warrant Holder shall be forced to
      exercise this Warrant within thirty (30) calendar days from the date the 30
      Day
      VWAP exceeds $2.00 per share (“Forced Exercise Period”). Any portion of this
      Warrant not exercise during the Forced Exercise Period shall terminate upon
      at
      the end of such period. This clause is also subject to a volume restriction
      of
      approximately 25% of the daily average volume. The Company can not force the
      investor to exercise into more than 4.9% clause below. 

     

    6. Maximum
      Exercise.
      The
      Warrant Holder shall not be entitled to exercise this Warrant
      on a Date of Exercise in connection with that number of shares of Common Stock
      which would be in excess of the sum of (i) the number of shares of Common Stock
      beneficially owned by the Warrant Holder and its affiliates on an exercise
      date,
      and (ii) the number of shares of Common Stock issuable upon the exercise of
      this
      Warrant with respect to which the determination of this limitation is being
      made
      on an exercise date, which would result in beneficial ownership by the Warrant
      Holder and its affiliates of more than 4.9% of the outstanding shares of Common
      Stock on such date. This Section 6 may be waived or amended only with the
      consent of the Holder and the consent of holders of a majority of the shares
      of
      outstanding Common Stock of the Company who are not Affiliates. For the purposes
      of the immediately preceding sentence, the term “Affiliate” shall mean any
      person: (a) that directly, or indirectly through one or more intermediaries,
      controls, or is controlled by, or is under common control with, the Company;
      or
      (b) who beneficially owns (i) any shares of the Company’s Series A Convertible
      Preferred Stock, (ii) the Company’s Common Stock Purchase Warrant “A” dated
      March 21, 2008, or (iii) this Warrant. For the purposes of the immediately
      preceding sentence, beneficial ownership shall be determined in accordance
      with
      Section 13(d) of the Securities Exchange Act of 1934, as amended, and Regulation
      13d-3 thereunder.

    7. Adjustment
      of Exercise Price and Number of Shares.
      The
      character of the shares of stock or other securities at the time issuable upon
      exercise of this Warrant and the Exercise Price therefore, are subject to
      adjustment upon the occurrence of the following events, and all such adjustments
      shall be cumulative:

     

    a. Adjustment
      for Stock Splits, Stock Dividends, Recapitalizations, Etc.
      The
      Exercise Price of this Warrant and the number of shares of Common Stock or
      other
      securities at the time issuable upon exercise of this Warrant shall be
      appropriately adjusted to reflect any stock dividend, stock split, combination
      of shares, reclassification, recapitalization or other similar event affecting
      the number of outstanding shares of stock or securities.

     

    b. Adjustment
      for Reorganization, Consolidation, Merger, Etc.
      In case
      of any consolidation or merger of the Company with or into any other
      corporation, entity or person, or any other corporate reorganization, in which
      the Company shall not be the continuing or surviving entity of such
      consolidation, merger or reorganization (any such transaction being hereinafter
      referred to as a "Reorganization"),
      then,
      in each case, the holder of this Warrant, on exercise hereof at any time after
      the consummation or effective date of such Reorganization (the "Effective
      Date"),
      shall
      receive, in lieu of the shares of stock or other securities at any time issuable
      upon the exercise of the Warrant issuable on such exercise prior to the
      Effective Date, the stock and other securities and property (including cash)
      to
      which such holder would have been entitled upon the Effective Date if such
      holder had exercised this Warrant immediately prior thereto (all subject to
      further adjustment as provided in this Warrant).

     

    c. Certificate
      as to Adjustments.
      In case
      of any adjustment or readjustment in the price or kind of securities issuable
      on
      the exercise of this Warrant, the Company will promptly give written notice
      thereof to the holder of this Warrant in the form of a certificate, certified
      and confirmed by the Board of Directors of the Company, setting forth such
      adjustment or readjustment and showing in reasonable detail the facts upon
      which
      such adjustment or readjustment is based.

     

    d. The
      Company fails to meet certain earnings per share
      projections.
      In the
      event the Company earns between $0.0670 and $0.0335 (50% Decline) per share
      (where such earnings in this paragraph shall always be defined as earnings
      on a
      pre tax fully diluted basis (including dilution from any options, warrants
      and
      convertible securities) as reported for the audited sixth months ended June
      30,
      2008 from continuing operations before any non-cash items the then current
      Exercise Price to the Investor at the time the audited numbers are reported
      to
      the SEC shall be decrease proportionately by 0% if the pre tax earnings (for
      first six months ended June 30, 2008) are $0.0670 per share or greater and
      by
      50% if the pre tax earnings (for first six months ended June 30, 2008) are
      $0.0335 per share (50% decrease). For example if the earnings are $0.0536 per
      share or less (20% Decline) then the then current Exercise Price to the investor
      shall be reduced by 20%. Such adjustment shall be made automatically within
      five
      business days of the audited numbers being reported to the SEC.

    e. In
      the
      event the Company earns between $0.1559 and $0.0780 (50% Decline) per share
      (where such earnings in this paragraph shall always be defined as earnings
      on a
      pre tax fully diluted basis (including dilution from any options, warrants
      and
      convertible securities) as reported for the audited fiscal year ending 2008
      from
      continuing operations before any non-cash items the then current Exercise Price
      to the Investor at the time the audited numbers are reported to the SEC shall
      be
      decrease proportionately by 0% if the pre tax earnings are $0.1559 per share
      or
      greater and by 50% if the pre tax earnings are $0.0780 per share (50% decrease).
      For example if the earnings are $ 0.1247 per share or less (20% Decline) then
      the then current Exercise Price to the investor shall be reduced by 20%. Such
      adjustment shall be made automatically within five business days of the audited
      numbers being reported to the SEC.

     

    f. The
      Company sells, grants or issues any shares, options, warrants, or any instrument
      convertible into shares or equity in any form below the exercise price per
      share
      of the warrant.
      In the
      event the Company sells, grants or issues any shares, options, warrants, or
      any
      instrument convertible into shares or equity in any form below the current
      exercise price per share of the warrant, then the current exercise price per
      share for the warrant shall be adjusted to a price determined by multiplying
      such exercise price by a fraction, the numerator of which shall be the number
      of
      shares of Common Stock Outstanding (defined below) immediately prior to such
      issuance plus the number of shares of Common Stock that the aggregate
      consideration received by the Company for such issuance would purchase at such
      exercise price; and the denominator of which shall be the number of shares
      of
      Common Stock Outstanding (as defined below) immediately prior to such issuance
      plus the number of shares issued at such issuance. For purposes of this
Section
      7(f),
      the
      term “Common Stock Outstanding” shall mean and include the following: (1)
      outstanding Common Stock, (2) Common Stock issuable upon conversion of
      outstanding Preferred Stock, (3) Common Stock issuable upon exercise of
      outstanding warrants. Shares described in (1) through (4) above shall be
      included whether vested or unvested, whether contingent or non-contingent and
      whether exercisable or not yet exercisable.

     

    8. Fractional
      Shares.
      The
      Company shall not be required to issue or cause to be issued fractional Warrant
      Shares on the exercise of this Warrant. The number of full Warrant Shares that
      shall be issuable upon the exercise of this Warrant shall be computed on the
      basis of the aggregate number of Warrants Shares purchasable on exercise of
      this
      Warrant so presented. If any fraction of a Warrant Share would, except for
      the
      provisions of this Section 8, be issuable on the exercise of this Warrant,
      the
      Company shall, at its option, (i) pay an amount in cash equal to the Exercise
      Price multiplied by such fraction or (ii) round the number of Warrant Shares
      issuable, up to the next whole number.

     

    9. Sale
      or Merger of the Company.
      Upon
      a
      Change in Control, the restriction contained in Section 6 shall immediately
      be
      released and the Warrant Holder will have the right to exercise this Warrant
      concurrently with such Change in Control event. For purposes of this Warrant,
      the term “Change in Control” shall mean a consolidation or merger of the Company
      with or into another company or entity in which the Company is not the surviving
      entity or the sale of all or substantially all of the assets of the Company
      to
      another company or entity not controlled by the then existing stockholders
      of
      the Company in a transaction or series of transactions.

      The
      Company will give Warrant Holder ten (10) business days notice before the event
      of a sale of all or substantially all of the assets of the Company or the merger
      or consolidation of the Company in a transaction in which the Company is not
      the
      surviving entity.

     

    11. Issuance
      of Substitute Warrant.
      In the
      event of a merger, consolidation, recapitalization or reorganization of the
      Company or a reclassification of Company shares of stock, which results in
      an
      adjustment to the number of shares subject to this Warrant and/or the Exercise
      Price hereunder, the Company agrees to issue to the Warrant Holder a substitute
      Warrant reflecting the adjusted number of shares and/or Exercise Price upon
      the
      surrender of this Warrant to the Company.
