      commencing on [ ], 2007 and prior to 5:00 P.M., New York City time, on [ ],

      (the “Exercise

      [________________] fully paid and non-assessable shares of common stock, $0.001
      par value per share, of the Company for a purchase price per share of

      Share Warrant Price";

      of the Holders")
      and (vii) the then Current Market Price per share of the Common Stock (the
      "Current
      Market Price")
      shall be deemed to be the last reported sale price of the Common Stock on the
      Trading Day (as defined below) immediately prior to such date or, in case no
      such reported sales take place on such day, the average of the last reported
      bid
      and asked prices of the Common Stock on such day, in either case on the
      principal national securities exchange on which the Common Stock is admitted
      to
      trading or listed, or if not listed or admitted to trading on any such exchange,
      the representative closing sale price of the Common Stock as reported by the
      Nasdaq Global Market or the Nasdaq Capital Market (collectively,
      “NASDAQ”),
      or other similar organization if NASDAQ is no longer reporting such information,
      or, if the Common Stock is not reported on NASDAQ, the per share sale price

      the Common Stock in the over-the-counter market as reported by the OTC Bulletin
      Board or another over-the-counter market, or if not so available, the fair
      market value of the Common Stock as determined in good faith by the Company’s
      Board of Directors. A "Trading
      Day"
      shall mean any day on which shares of the Company’s Common Stock are sold on the
      respective exchange or over-the-counter market. The Aggregate Warrant Price
      is
      not subject to adjustment.

     

    
      
         

      

      
         

        
          

        

      

      
         

      

    

     

    This
      Warrant is one in a series of related warrants constituting in the aggregate
      Warrants to purchase [ ] Warrant Shares, which were originally issued pursuant
      to a series of Note and Warrant Purchase Agreements (the “Purchase
      Agreements”)
      between the Company and the investors named therein in connection with a private
      placement by the Company of its securities, as described in the Company’s
      Confidential Private Placement Memorandum dated June 20, 2007. By acceptance
      of
      this Warrant, the Holder agrees to comply with all applicable provisions of
      the
      Purchase Agreement.

    


    1. Exercise
      of Warrant.
      

    


    (a) This
      Warrant may be exercised in whole at any time, or in part from time to time,
      by
      the Holder during the Exercise Period:

    


    (i) by
      the surrender of this Warrant (with the subscription form at the end hereof
      duly
      executed) at the address set forth in subsection 10(a) hereof, together with
      proper payment of the Aggregate Warrant Price, or the proportionate part thereof
      if this Warrant is exercised in part, with payment for the Warrant Shares made
      by certified or official bank check payable to the order of, or wire transfer
      of
      immediately available funds to, the Company; or

    


    (ii) if
      at any time following the first anniversary of the Issuance Date the sale of
      the
      Warrant Shares by the Holder is not then registered under the Act pursuant
      to an
      effective registration statement, by the surrender of this Warrant (with the
      cashless exercise form at the end hereof duly executed) (a “Cashless
      Exercise”)
      at the address set forth in subsection 10(a) hereof. Such presentation and
      surrender shall be deemed a waiver of the Holder's obligation to pay the
      Aggregate Warrant Price, or the proportionate part thereof if this Warrant
      is
      exercised in part. In the event of a Cashless Exercise, the Holder shall
      exchange its Warrant for that number of Warrant Shares subject to such Cashless
      Exercise multiplied by a fraction, the numerator of which shall be the
      difference between the then Current Market Price and the Per Share Warrant
      Price, and the denominator of which shall be the then Current Market Price.
      For
      purposes of any computation under this subsection 1(a), the then Current Market
      Price shall be based on the Trading Day immediately preceding such Cashless
      Exercise.

    


    (b) If
      this Warrant is exercised in part, this Warrant must be exercised for a number
      of whole shares of the Common Stock and the Holder is entitled to receive a
      new
      Warrant covering the Warrant Shares that have not been exercised and setting
      forth the proportionate part of the Aggregate Warrant Price applicable to such
      Warrant Shares. Upon surrender of this Warrant in connection with the exercise
      of this Warrant pursuant to the terms hereof, the Company will (i) as soon
      as
      practicable but no later than three business days after the due exercise of
      this
      Warrant (the “Warrant
      Share Delivery Date”),
      issue a certificate or certificates in the name of the Holder for the largest
      number of whole shares of the Common Stock to which the Holder shall be entitled
      upon such exercise and, if this Warrant is exercised in whole, in lieu of any
      fractional share of the Common Stock to which the Holder shall be entitled,
      pay
      to the Holder cash in an amount equal to the fair value of such fractional
      share
      (determined in such reasonable manner as the Board of Directors of the Company
      shall determine), and (ii) deliver the other securities and properties
      receivable upon the exercise of this Warrant, or the proportionate part thereof,
      if this Warrant is exercised in part, pursuant to the provisions of this
      Warrant.

    


    (c) In
      addition to any other rights available to the Holder, if the Company fails
      to
      cause its transfer agent to transmit to the Holder a certificate or certificates
      representing the Warrant Shares pursuant to an exercise on or before the Warrant
      Share Delivery Date, and if after such date the Holder is required by its broker
      to purchase (in an open market transaction or otherwise) shares of Common Stock
      to deliver in satisfaction of a sale by the Holder of the Warrant Shares which
      the Holder anticipated receiving upon such exercise (a “Buy-In”),
      then
      the Company shall (1) pay in cash to the Holder the amount by which (x) the
      Holder’s total purchase price (including brokerage commissions, if any) for the
      shares of Common Stock so purchased exceeds (y) the amount obtained by
      multiplying (A) the number of Warrant Shares that the Company was required
      to
      deliver to the Holder in connection with the exercise at issue times (B) the
      price at which the sell order giving rise to such purchase obligation was
      executed, and (2) at the option of the Holder, either reinstate the portion
      of
      the Warrant and equivalent number of Warrant Shares for which such exercise
      was
      not honored or deliver to the Holder the number of shares of Common Stock that
      would have been issued had the Company timely complied with its exercise and
      delivery obligations hereunder. For example, if the Holder purchases Common
      Stock having a total purchase price of $11,000 to cover a Buy-In with respect
      to
      an attempted exercise of shares of Common Stock with an aggregate sale price
      giving rise to such purchase obligation of $10,000, under clause (1) of the
      immediately preceding sentence the Company shall be required to pay the Holder
      $1,000. The Holder shall provide the Company written notice indicating the
      amounts payable to the Holder in respect of the Buy-In, together with applicable
      confirmations and other evidence reasonably requested by the Company. Nothing
      herein shall limit a Holder’s right to pursue any other remedies available to it
      hereunder, at law or in equity including, without limitation, a decree of
      specific performance and/or injunctive relief with respect to the Company’s
      failure to timely deliver certificates representing shares of Common Stock
      upon
      exercise of the Warrant as required pursuant to the terms hereof.

    2. Reservation
      of Warrant Shares; Listing.
      

    


    The
      Company agrees that, prior to the expiration of this Warrant, the Company shall
      at all times (a) have authorized and in reserve, and shall keep available,
      solely for issuance and delivery upon the exercise of this Warrant, the shares
      of the Common Stock and other securities and properties as from time to time
      shall be receivable upon the exercise of this Warrant, free and clear of all
      restrictions on sale or transfer, other than under Federal or state securities
      laws, and free and clear of all preemptive rights and rights of first refusal
      and (b) if the Company hereafter lists its Common Stock on any national
      securities exchange or NASDAQ, use its commercially reasonable efforts to keep
      the Warrant Shares authorized for listing on such exchange upon notice of
      issuance.

    


    3. Certain
      Adjustments.
      

     

    (a) In
      case the Company shall hereafter (i) pay a dividend or make a distribution
      on
      its Common Stock in shares of Common Stock, (ii) subdivide its outstanding
      shares of Common Stock into a greater number of shares, (iii) combine or
      reverse-split its outstanding shares of Common Stock into a smaller number
      of
      shares or (iv) issue by reclassification of its Common Stock any shares of
      capital stock of the Company, then the Per Share Warrant Price and the number
      of
      Warrant Shares shall forthwith be proportionately decreased and increased,
      respectively, in the case of a subdivision, distribution or stock dividend,
      or
      proportionately increased and decreased, respectively, in the case of a
      combination or reverse stock split. The Aggregate Warrant Price payable for
      the
      then total number
      of
      Warrant
      Shares available for exercise under this Warrant shall remain the same.
      Adjustments made pursuant to this subsection 3(a) shall become effective on
      the
      record date in the case of a dividend or distribution, and shall become
      effective immediately after the effective date in the case of a subdivision,
      combination or reclassification. If such dividend, distribution, subdivision
      or
      combination is not consummated in full, the Per Share Warrant Price and Warrant
      Shares shall be readjusted accordingly.

     

    
      
         

      

      
        3

        
          

        

      

      
         

      

    

     

    (b) In
      case of any capital reorganization or reclassification, or any consolidation
      or
      merger to which the Company is a party other than a merger or consolidation
      in
      which the Company is the continuing corporation, or in case of any sale or
      conveyance to another entity of all or substantially all of the assets of the
      Company, or in the case of any statutory exchange of securities with another
      corporation (including any exchange effected in connection with a merger of
      a
      third corporation into the Company but excluding any exchange of securities
      or
      merger with another corporation in which the Company is a continuing corporation
      and that does not result in any reclassification of or similar change in the
      Common Stock), the Holder of this Warrant shall have the right thereafter to
      receive on the exercise of this Warrant the kind and amount of securities,
      cash
      or other property which the Holder would have owned or have been entitled to
      receive immediately after such reorganization, reclassification, consolidation,
      merger, statutory exchange, sale or conveyance had this Warrant been exercised
      immediately prior to the effective date of such reorganization,
      reclassification, consolidation, merger, statutory exchange, sale or conveyance
      and in any such case, if necessary, appropriate adjustment shall be made in
      the
      application of the provisions set forth in this Section 3 with respect to the
      rights and interests thereafter of the Holder of this Warrant to the end that
      the provisions set forth in this Section 3 shall thereafter correspondingly
      be
      made applicable, as nearly as may reasonably be, in relation to any shares
      of
      stock or other securities or property thereafter deliverable on the exercise
      of
      this Warrant. The above provisions of this subsection 3(b) shall similarly
      apply
      to successive reorganizations, reclassifications, consolidations, mergers,
      statutory exchanges, sales or conveyances. The Company shall require the issuer
      of any shares of stock or other securities or property thereafter deliverable
      on
      the exercise of this Warrant to be responsible for all of the agreements and
      obligations of the Company hereunder. Notice of any such reorganization,
      reclassification, consolidation, merger, statutory exchange, sale or conveyance
      and of said provisions so proposed to be made, shall be mailed to the Holders
      of
      the Warrants not less than twenty (20) days prior to such event. A sale of
      all
      or substantially all of the assets of the Company for a consideration consisting
      primarily of securities shall be deemed a consolidation or merger for the
      foregoing purposes.

    


    (c) No
      adjustment in the Per Share Warrant Price shall be required unless such
      adjustment would require an increase or decrease of at least $0.01 per share
      of
      Common Stock; provided,
      however,
      that any adjustments which by reason of this subsection 3(c) are not required
      to
      be made shall be carried forward and taken into account in any subsequent
      adjustment; provided,
      further,
      however, that adjustments shall be required and made in accordance with the
      provisions of this Section 3 (other than this subsection 3(c)) not later than
      such time as may be required in order to preserve the tax-free nature of a
      distribution, if any, to the Holder of this Warrant or Common Stock issuable
      upon the exercise hereof. All calculations under this Section 3 shall be made
      to
      the nearest cent or to the nearest 1/100th of a share, as the case may be.
      Anything in this Section 3 to the contrary notwithstanding, the Company shall
      be
      entitled to make such reductions in the Per Share Warrant Price, in addition
      to
      those required by this Section 3, as it in its discretion shall deem to be
      advisable in order that any stock dividend, subdivision of shares or
      distribution of rights to purchase stock or securities convertible or
      exchangeable for stock hereafter made by the Company to its stockholders shall
      not be taxable.

    


    (d) Whenever
      the Per Share Warrant Price or the number of Warrant Shares is adjusted as
      provided in this Section 3 and upon any modification of the rights of a Holder
      of Warrants in accordance with this Section 3, the Company shall promptly
      prepare a brief statement of the facts requiring such adjustment or modification
      and the manner of computing the same and cause copies of such certificate to
      be
      mailed to the Holders of the Warrants. The Company may, but shall not be
      obligated to unless requested by a Majority of the Holders, obtain, at its
      expense, a certificate of a firm of independent public accountants of recognized
      standing selected by the Board of Directors (who may be the regular auditors
      of
      the Company) setting forth the Per Share Warrant Price and the number of Warrant
      Shares in effect after such adjustment or the effect of such modification,
      a
      brief statement of the facts requiring such adjustment or modification and
      the
      manner of computing the same and cause copies of such certificate to be mailed
      to the Holders of the Warrants.

    (e) If
      the Board of Directors of the Company shall declare any dividend or other
      distribution with respect to the Common Stock other than a cash distribution
      out
      of earned surplus, the Company shall mail notice thereof to the Holders of
      the
      Warrants not less than ten (10) days prior to the record date fixed for
      determining stockholders entitled to participate in such dividend or other
      distribution.

    


    (f) If,
      as a result of an adjustment made pursuant to this Section 3, the Holder of
      any
      Warrant thereafter surrendered for exercise shall become entitled to receive
      shares of two or more classes of capital stock or shares of Common Stock and
      other capital stock of the Company, the Board of Directors (whose determination
      shall be conclusive and shall be described in a written notice to the Holder
      of
      any Warrant promptly after such adjustment) shall determine, in good faith,
      the
      allocation of the adjusted Per Share Warrant Price between or among shares
      or
      such classes of capital stock or shares of Common Stock and other capital
      stock.

     

    (g) Upon
      the expiration of any rights, options, warrants or conversion privileges with
      respect to the issuance of which an adjustment to the Per Share Warrant Price
      had been made, if such option, right warrant or conversion shall not have been
      exercised, the number of Warrant Shares purchasable upon exercise of this
      Warrant, to the extent this Warrant has not then been exercised, shall, upon
      such expiration, be readjusted and shall thereafter be such as they would have
      been had they been originally adjusted (or had the original adjustment not
      been
      required, as the case may be) on the basis of (A) the fact that Common Stock,
      if
      any, actually issued or sold upon the exercise of such rights, options, warrants
      or conversion privileges, and (B) the fact that such shares of Common Stock,
      if
      any, were issued or sold for the consideration actually received by the Company
      upon such exercise plus the consideration, if any, actually received by the
      Company for the issuance, sale or grant of all such rights, options, warrants
      or
      conversion privileges whether or not exercised; provided,
      however,
      that no such readjustment shall have the effect of decreasing the number of
      Warrant Shares purchasable upon exercise of this Warrant by an amount in excess
      of the amount of the adjustment initially made in respect of the issuance,
      sale
      or grant of such rights, options, warrants or conversion
      privileges.

    


    (h) In
      case any event shall occur as to which the other provisions of this Section
      3
      are not strictly applicable but as to which the failure to make any adjustment
      would not fairly protect the purchase rights represented by this Warrant in
      accordance with the essential intent and principles of the adjustments set
      forth
      in this Section 3 then, in each such case, the Board of Directors of the Company
      shall in good faith determine the adjustment, if any, on a basis consistent
      with
      the essential intent and principles established herein, necessary to preserve
      the purchase rights represented by the Warrants. Upon such determination, the
      Company will promptly mail a copy thereof to the Holder of this Warrant and
      shall make the adjustments described therein.

    


    4. Fully
      Paid Stock; Taxes.
      The shares of the Common Stock represented by each and every certificate for
      Warrant Shares delivered on the exercise of this Warrant shall, subject to
      compliance by the Holder with the terms hereof, at the time of such delivery,
      be
      duly authorized, validly issued and outstanding, fully paid and nonassessable,
      and not subject to preemptive rights or rights of first refusal imposed by
      any
      agreement to which the Company is a party, and the Company will take all such
      actions as may be necessary to assure that the par value, if any, per share
      of
      the Common Stock is at all times equal to or less than the then Per Share
      Warrant Price. The Company shall pay, when due and payable, any and all Federal
      and state stamp, original issue or similar taxes which may be payable in respect
      of the issue of any Warrant Share or any certificate thereof to the extent
      required because of the issuance by the Company of such security.

    5. Registration
      Under Act.
      

    


    (a) The
      Holder shall have the right to participate in the registration rights granted
      to
      purchasers of the Securities (as defined in the Purchase Agreement) pursuant
      to
      Article 5 of the Purchase Agreement. By acceptance of this Warrant, the Holder
      agrees to comply with the provisions in Article 5 of the Purchase Agreement
      to
      the same extent as if it were a party thereto.

    


    (b) Until
      all of the Warrant Shares and any shares of Common Stock issuable thereunder
      have been sold under a Registration Statement or pursuant to Rule 144(k), so
      long as the Company’s Common Stock remains registered under the Act, the Company
      shall use its commercially reasonable efforts to file with the Securities and
      Exchange Commission all current reports and the information as may be necessary
      to enable the Holder to effect sales of its shares in reliance upon Rule 144(k)
      promulgated under the Act.

    


    6. Investment
      Intent; Limited Transferability. 

    


    (a) By
      accepting this Warrant, the Holder represents to the Company that it understands
      that this Warrant and any securities obtainable upon exercise of this Warrant
      have not been registered for sale under Federal or state securities laws and
      are
      being offered and sold to the Holder pursuant to one or more exemptions from
      the
      registration requirements of such securities laws. In the absence of an
      effective registration of such securities or an exemption therefrom, any
      certificates for such securities shall bear the legend set forth on the first
      page hereof. The Holder understands that it must bear the economic risk of
      its
      investment in this Warrant and any securities obtainable upon exercise of this
      Warrant for an indefinite period of time, as this Warrant and such securities
      have not been registered under Federal or state securities laws and therefore
      cannot be sold unless subsequently registered under such laws, unless an
      exemption from such registration is available. The Holder further represents
      to
      the Company, by accepting this Warrant, that it has full power and authority
      to
      accept this Warrant and make the representations set forth herein.

    


    (b) The
      Holder, by its acceptance of this Warrant, represents to the Company that it
      is
      acquiring this Warrant and will acquire any securities obtainable upon exercise
      of this Warrant for its own account for investment and not with a view to,
      or
      for sale in connection with, any distribution thereof in violation of the Act.
      The Holder agrees, by acceptance of this Warrant, that this Warrant and any
      such
      securities will not be sold or otherwise transferred unless (i) a registration
      statement with respect to such transfer is effective under the Act and any
      applicable state securities laws or (ii) such sale or transfer is made pursuant
      to one or more exemptions from the Act. 

    


    (c) In
      addition to the limitations set forth in Section 1 and in accordance with the
      legend on the first page hereof, this Warrant may not be sold, transferred,
      assigned or hypothecated by the Holder except in compliance with the provisions
      of the Act and the applicable state securities “blue sky” laws, and is so
      transferable only upon the books of the Company which it shall cause to be
      maintained for such purpose. The Company may treat the registered Holder of
      this
      Warrant as it appears on the Company's books at any time as the Holder for
      all
      purposes. The Company shall permit any Holder of a Warrant or its duly
      authorized attorney, upon written request during ordinary business hours, to
      inspect and copy or make extracts from its books showing the registered Holders
      of Warrant. All Warrants issued upon the transfer or assignment of this Warrant
      will be dated the same date as this Warrant, and all rights of the holder
      thereof shall be identical to those of the Holder unless, in each case,
      otherwise prohibited by applicable law.

    (d) The
      Holder has been afforded (i) the opportunity to ask such questions as it has
      deemed necessary of, and to receive answers from, representatives of the Company
      concerning the terms and conditions of the Warrants or the exercise of the
      Warrants; and (ii) the opportunity to request such additional information which
      the Company possesses or can acquire without unreasonable effort or
      expense.

    


    (e) The
      Holder did not (i) receive or review any advertisement, article, notice or
      other
      communication published in a newspaper or magazine or similar media or broadcast
      over television or radio, whether closed circuit, or generally available; or
      (ii) attend any seminar, meeting or investor or other conference whose attendees
      were, to such Holder’s knowledge, invited by any general solicitation or general
      advertising.

    


    (f) The
      Holder is an “accredited investor” within the meaning of Regulation D under the
      Act. Such Holder is acquiring the Warrants for its own account and not with
      a
      present view to, or for sale in connection with, any distribution thereof in
      violation of the registration requirements of the Act, without prejudice,
      however, to such Holder’s right, subject to the provisions of the Purchase
      Agreement and this Warrant, at all times to sell or otherwise dispose of all
      or
      any part of such Warrants and Warrant Shares.

    


    (g) Either
      by reason of such Holder’s business or financial experience or the business or
      financial experience of its professional advisors (who are unaffiliated with
      and
      who are not compensated by the Company or any affiliate, finder or selling
      agent
      of the Company, directly or indirectly), such Holder has the capacity to protect
      such Holder’s interests in connection with the transactions contemplated by this
      Warrant and the Purchase Agreement. The Holder, by its acceptance of this
      Warrant, represents to the Company that it is able to fend for itself, can
      bear
      the economic risk of its investment and has such knowledge and experience in
      financial or business matters that it is capable of evaluating the merits and
      risks of the investment in this Warrant. Holder also represents it has not
      been
      organized for the purpose of acquiring this Warrant.

     

    7.
      Optional Redemption. 

    


    (a) In
      the event that the closing price of the Common Stock for any twenty (20)
      consecutive trading days on the OTC Bulletin Board (or upon a national
      securities exchange or the NASDAQ, if then applicable) is at least $1.50
      (subject to adjustment for any stock splits, combinations, or similar events
      with respect to the Common Stock after the original issuance date of this
      Warrant, as described in Section 3 hereof) (the “Redemption
      Price”),
      the Company shall be entitled to redeem all, but not less than all, of the
      Warrants at a per Warrant redemption price of $0.001, at any time after the
      completion of such twenty (20) consecutive trading day period by providing
      thirty (30) business days’ written notice to the Holders. The Holder agrees to
      return the certificate representing the redeemed Warrants to the Company upon
      their redemption (or evidence reasonably satisfactory to the Company of the
      loss, theft, destruction or mutilation of this Warrant in accordance with
      Section 8 hereof). 

    


    (b) Notwithstanding
      Section 7(a) hereof, for so long as any Warrant Shares are not subject to a
      registration statement providing for the resale thereof under the Securities
      Act
      declared effective by the SEC or are not otherwise permitted to be immediately
      sold, in whole, pursuant to an exemption to registration for such resale
      pursuant to Rule 144(k) of the Act, the Company shall not be entitled to
      exercise its redemption rights pursuant to Section 7(a) above.

    


    8. Loss,
      etc., of Warrant.
      Upon receipt of evidence reasonably satisfactory to the Company of the loss,
      theft, destruction or mutilation of this Warrant, and of indemnity reasonably
      satisfactory to the Company, if lost, stolen or destroyed, and upon surrender
      and cancellation of this Warrant, if mutilated, the Company shall execute and
      deliver to the Holder a new Warrant of like date, tenor and
      denomination.

      to

      matters whatsoever, nor any other rights or liabilities as a stockholder, prior
      to the exercise hereof; this Warrant does, however, require certain notices
      to
      Holders as set forth herein.

      of
      the State of New York without giving effect to the principles of conflicts
      of

    13. Amendment,
      Waiver, etc.
      Except as expressly provided herein, neither this Warrant nor any term hereof
      may be amended, waived, discharged or terminated other than by a written
