    FOR
      VALUE RECEIVED,
      ADVANCED BIOPHOTONICS INC.,
      a
      Delaware corporation (hereinafter called the “Borrower”),
      hereby promises to pay to the order of AJW QUALIFIED PARTNERS, LLC or registered
      assigns (the “Holder”)
      the
      sum of $300,000, on October 31, 2009 (the “Maturity
      Date”),
      and
      to pay interest on the unpaid principal balance hereof at the rate of eight
      percent (8%) (the “Interest
      Rate”)
      per
      annum from October 31, 2006 (the “Issue
      Date”)
      until
      the same becomes due and payable, whether at maturity or upon acceleration
      or by
      prepayment or otherwise. Any amount of principal or interest on this Note which
      is not paid when due shall bear interest at the rate of fifteen percent (15%)
      per annum from the due date thereof until the same is paid (“Default
      Interest”).
      Interest shall commence accruing on the Issue Date, shall be computed on the
      basis of a 365-day year and the actual number of days elapsed and shall be
      payable quarterly provided that no interest shall be due and payable for any
      month in which the Trading Price (as such term is defined below) is greater
      than
      $.10 for each Trading Day (as such term is defined below) of the month. All
      payments due hereunder (to the extent not converted into common stock, $.001
      par
      value per share (the “Common
      Stock”)
      in
      accordance with the terms hereof) shall be made in lawful money of the United
      States of America. All payments shall be made at such address as the Holder
      shall hereafter give to the Borrower by written notice made in accordance with
      the provisions of this Note. Whenever any amount expressed to be due by the
      terms of this Note is due on any day which is not a business day, the same
      shall
      instead be due on the next succeeding day which is a business day and, in the
      case of any interest payment date which is not the date on which this Note
      is
      paid in full, the extension of the due date thereof shall not be taken into
      account for purposes of determining the amount of interest due on such date.
      As
      used in this Note, the term “business day” shall mean any day other than a
      Saturday, Sunday or a day on which commercial banks in the city of New York,
      New
      York are authorized or required by law or executive order to remain closed.
      Each
      capitalized term used herein, and not otherwise defined, shall have the meaning
      ascribed thereto in that certain Securities Purchase Agreement, dated October
      31, 2006, pursuant to which this Note was originally issued (the “Purchase
      Agreement”).

     

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

     

    This
      Note
      is free from all taxes, liens, claims and encumbrances with respect to the
      issue
      thereof and shall not be subject to preemptive rights or other similar rights
      of
      shareholders of the Borrower and will not impose personal liability upon the
      holder thereof. The obligations of the Borrower under this Note shall be secured
      by that certain Security Agreement and Intellectual Property Security Agreement,
      each dated October 31, 2006 by and between the Borrower and the
      Holder.

     

    The
      following terms shall apply to this Note:

     

    ARTICLE
      I.  CONVERSION
      RIGHTS

     

    1.1  Conversion
      Right.
      The
      Holder shall have the right from time to time, and at any time on or prior
      to
      the earlier of (i) the Maturity Date and (ii) the date of payment of the Default
      Amount (as defined in Article III) pursuant to Section 1.6(a) or Article III,
      the Optional Prepayment Amount (as defined in Section 5.1 or any payments
      pursuant to Section 1.7, each in respect of the remaining outstanding principal
      amount of this Note to convert all or any part of the outstanding and unpaid
      principal amount of this Note into fully paid and non-assessable shares of
      Common Stock, as such Common Stock exists on the Issue Date, or any shares
      of
      capital stock or other securities of the Borrower into which such Common Stock
      shall hereafter be changed or reclassified at the conversion price (the
“Conversion
      Price”)
      determined as provided herein (a “Conversion”);
      provided,
      however,
      that in
      no event shall the Holder be entitled to convert any portion of this Note in
      excess of that portion of this Note upon conversion of which the sum of (1)
      the
      number of shares of Common Stock beneficially owned by the Holder and its
      affiliates (other than shares of Common Stock which may be deemed beneficially
      owned through the ownership of the unconverted portion of the Notes or the
      unexercised or unconverted portion of any other security of the Borrower
      (including, without limitation, the warrants issued by the Borrower pursuant
      to
      the Purchase Agreement) subject to a limitation on conversion or exercise
      analogous to the limitations contained herein) and (2) the number of shares
      of
      Common Stock issuable upon the conversion of the portion of this Note with
      respect to which the determination of this proviso is being made, would result
      in beneficial ownership by the Holder and its affiliates of more than 4.99%
      of
      the outstanding shares of Common Stock and provided further
      that the
      Holder shall not be entitled to convert any portion of this Note during any
      month immediately succeeding a Determination Date on which the Borrower
      exercises its prepayment option pursuant to Section 5.2 of this Note. For
      purposes of the proviso to 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 Regulations 13D-G thereunder, except
      as
      otherwise provided in clause (1) of such proviso. The number of shares of Common
      Stock to be issued upon each conversion of this Note shall be determined by
      dividing the Conversion Amount (as defined below) by the applicable Conversion
      Price then in effect on the date specified in the notice of conversion, in
      the
      form attached hereto as Exhibit A (the “Notice
      of Conversion”),
      delivered to the Borrower by the Holder in accordance with Section 1.4 below;
      provided that the Notice of Conversion is submitted by facsimile (or by other
      means resulting in, or reasonably expected to result in, notice) to the Borrower
      before 6:00 p.m., New York, New York time on such conversion date (the
“Conversion
      Date”).
      The
      term “Conversion
      Amount”
means,
      with respect to any conversion of this Note, the sum of (1) the principal amount
      of this Note to be converted in such conversion plus
      (2)
      accrued and unpaid interest, if any, on such principal amount at the interest
      rates provided in this Note to the Conversion Date, provided, however, that
      the
      Company shall have the right to pay any or all interest in cash plus
      (3)
      Default Interest, if any, on the amounts referred to in the immediately
      preceding clauses (1) and/or (2) plus
      (4) at
      the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and
      1.4(g) hereof or pursuant to Section 2(c) of that certain Registration Rights
      Agreement, dated as of October 31, 2006, executed in connection with the initial
      issuance of this Note and the other Notes issued on the Issue Date (the
“Registration
      Rights Agreement”).
      The
      term “Determination
      Date” means
      the
      last business day of each month after the Issue Date.

    1.2  Conversion
      Price.

     

    (a)  Calculation
      of Conversion Price.
      The
      Conversion Price shall be the Variable Conversion Price (as defined herein)
      (subject, in each case, to equitable adjustments for stock splits, stock
      dividends or rights offerings by the Borrower relating to the Borrower’s
      securities or the securities of any subsidiary of the Borrower, combinations,
      recapitalization, reclassifications, extraordinary distributions and similar
      events). The “Variable
      Conversion Price”
shall
      mean the Applicable Percentage (as defined herein) multiplied by the Market
      Price (as defined herein). “Market
      Price”
means
      the average of the lowest three (3) Trading Prices (as defined below) for the
      Common Stock during the twenty (20) Trading Day period ending one Trading Day
      prior to the date the Conversion Notice is sent by the Holder to the Borrower
      via facsimile (the “Conversion
      Date”).
      “Trading
      Price”
means,
      for any security as of any date, the intraday trading price on the
      Over-the-Counter Bulletin Board (the “OTCBB”)
      as
      reported by a reliable reporting service (“Reporting
      Service”)
      mutually acceptable to Borrower and Holder and hereafter designated by Holders
      of a majority in interest of the Notes and the Borrower or, if the OTCBB is
      not
      the principal trading market for such security, the intraday trading price
      of
      such security on the principal securities exchange or trading market where
      such
      security is listed or traded or, if no intraday trading price of such security
      is available in any of the foregoing manners, the average of the intraday
      trading prices of any market makers for such security that are listed in the
      “pink sheets” by the National Quotation Bureau, Inc. If the Trading Price cannot
      be calculated for such security on such date in the manner provided above,
      the
      Trading Price shall be the fair market value as mutually determined by the
      Borrower and the holders of a majority in interest of the Notes being converted
      for which the calculation of the Trading Price is required in order to determine
      the Conversion Price of such Notes. “Trading
      Day”
shall
      mean any day on which the Common Stock is traded for any period on the OTCBB,
      or
      on the principal securities exchange or other securities market on which the
      Common Stock is then being traded. “Applicable
      Percentage”
shall
      mean 60.0%.

     

    (b)  Conversion
      Price During Major Announcements.
      Notwithstanding
      anything contained in Section 1.2(a) to the contrary, in the event the Borrower
      (i) makes a public announcement that it intends to consolidate or merge with
      any
      other corporation (other than a merger in which the Borrower is the surviving
      or
      continuing corporation and its capital stock is unchanged) or sell or transfer
      all or substantially all of the assets of the Borrower or (ii) any person,
      group
      or entity (including the Borrower) publicly announces a tender offer to purchase
      50% or more of the Borrower’s Common Stock (or any other takeover scheme) (the
      date of the announcement referred to in clause (i) or (ii) is hereinafter
      referred to as the “Announcement
      Date”),
      then
      the Conversion Price shall, effective upon the Announcement Date and continuing
      through the Adjusted Conversion Price Termination Date (as defined below),
      be
      equal to the lower of (x) the Conversion Price which would have been applicable
      for a Conversion occurring on the Announcement Date and (y) the Conversion
      Price
      that would otherwise be in effect. From and after the Adjusted Conversion Price
      Termination Date, the Conversion Price shall be determined as set forth in
      this
      Section 1.2(a). For purposes hereof, “Adjusted
      Conversion Price Termination Date”
shall
      mean, with respect to any proposed transaction or tender offer (or takeover
      scheme) for which a public announcement as contemplated by this Section 1.2(b)
      has been made, the date upon which the Borrower (in the case of clause (i)
      above) or the person, group or entity (in the case of clause (ii) above)
      consummates or publicly announces the termination or abandonment of the proposed
      transaction or tender offer (or takeover scheme) which caused this Section
      1.2(b) to become operative.

    1.3  Authorized
      Shares.
      Subject
      to Stockholder Approval (as such term is defined in Section 4(n) of the
      Securities Purchase Agreement), the Borrower covenants that during the period
      the conversion right exists, the Borrower will reserve from its authorized
      and
      unissued Common Stock a sufficient number of shares, free from preemptive
      rights, to provide for the issuance of Common Stock upon the full conversion
      of
      this Note and the other Notes issued pursuant to the Purchase Agreement. The
      Borrower is required at all times to have authorized and reserved two times
      the
      number of shares that is actually issuable upon full conversion of the Notes
      (based on the Conversion Price of the Notes or the Exercise Price of the
      Warrants in effect from time to time) (the “Reserved
      Amount”).
      The
      Reserved Amount shall be increased from time to time in accordance with the
      Borrower’s obligations pursuant to Section 4(h) of the Purchase Agreement. The
      Borrower represents that upon issuance, such shares will be duly and validly
      issued, fully paid and non-assessable. In addition, if the Borrower shall issue
      any securities or make any change to its capital structure which would change
      the number of shares of Common Stock into which the Notes shall be convertible
      at the then current Conversion Price, the Borrower shall at the same time make
      proper provision so that thereafter there shall be a sufficient number of shares
      of Common Stock authorized and reserved, free from preemptive rights, for
      conversion of the outstanding Notes. The Borrower (i) acknowledges that it
      has
      irrevocably instructed its transfer agent to issue certificates for the Common
      Stock issuable upon conversion of this Note, and (ii) agrees that its
      issuance of this Note shall constitute full authority to its officers and agents
      who are charged with the duty of executing stock certificates to execute and
      issue the necessary certificates for shares of Common Stock in accordance with
      the terms and conditions of this Note.

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    
       

      If,
        at
        any time a Holder of this Note submits a Notice of Conversion, and the Borrower
        does not have sufficient authorized but unissued shares of Common Stock
        available to effect such conversion in accordance with the provisions of
        this
        Article I (a “Conversion
        Default”),
        subject to Section 4.8, the Borrower shall issue to the Holder all of the
        shares
        of Common Stock which are then available to effect such conversion. The portion
        of this Note which the Holder included in its Conversion Notice and which
        exceeds the amount which is then convertible into available shares of Common
        Stock (the “Excess
        Amount”)
        shall,
        notwithstanding anything to the contrary contained herein, not be convertible
        into Common Stock in accordance with the terms hereof until (and at the Holder’s
        option at any time after) the date additional shares of Common Stock are
        authorized by the Borrower to permit such conversion, at which time the
        Conversion Price in respect thereof shall be the lesser of (i) the Conversion
        Price on the Conversion Default Date (as defined below) and (ii) the Conversion
        Price on the Conversion Date thereafter elected by the Holder in respect
        thereof. In addition, the Borrower shall pay to the Holder payments
        (“Conversion
        Default Payments”)
        for a
        Conversion Default in the amount of (x) the sum
        of
        (1) the
        then outstanding principal amount of this Note plus
        (2)
        accrued and unpaid interest on the unpaid principal amount of this Note through
        the Authorization Date (as defined below) plus
        (3)
        Default Interest, if any, on the amounts referred to in clauses (1) and/or
        (2),
multiplied
        by
        (y) .24,
multiplied
        by
        (z)
        (N/365), where N = the number of days from the day the holder submits a Notice
        of Conversion giving rise to a Conversion Default (the “Conversion
        Default Date”)
        to the
        date (the “Authorization
        Date”)
        that
        the Borrower authorizes a sufficient number of shares of Common Stock to
        effect
        conversion of the full outstanding principal balance of this Note. The Borrower
        shall use its best efforts to authorize a sufficient number of shares of
        Common
        Stock as soon as practicable following the earlier of (i) such time that
        the
        Holder notifies the Borrower or that the Borrower otherwise becomes aware
        that
        there are or likely will be insufficient authorized and unissued shares to
        allow
        full conversion thereof and (ii) a Conversion Default. The Borrower shall
        send
        notice to the Holder of the authorization of additional shares of Common
        Stock,
        the Authorization Date and the amount of Holder’s accrued Conversion Default
        Payments. The accrued Conversion Default Payments for each calendar month
        shall
        be paid in cash or shall be convertible into Common Stock (at such time as
        there
        are sufficient authorized shares of Common Stock) at the applicable Conversion
        Price, at the Borrower’s option, as follows:

    

     

    (a)  In
      the
      event Holder elects to take such payment in cash, cash payment shall be made
      to
      Holder by the fifth (5th)
      day of
      the month following the month in which it has accrued; and

     

    (b)  In
      the
      event Holder elects to take such payment in Common Stock, the Holder may convert
      such payment amount into Common Stock at the Conversion Price (as in effect
      at
      the time of conversion) at any time after the fifth day of the month following
      the month in which it has accrued in accordance with the terms of this Article
      I
      (so long as there is then a sufficient number of authorized shares of Common
      Stock).

     

    The
      Holder’s election shall be made in writing to the Borrower at any time prior to
      6:00 p.m., New York, New York time, on the third day of the month following
      the
      month in which Conversion Default payments have accrued. If no election is
      made,
      the Holder shall be deemed to have elected to receive cash. Nothing herein
      shall
      limit the Holder’s right to pursue actual damages (to the extent in excess of
      the Conversion Default Payments) for the Borrower’s failure to maintain a
      sufficient number of authorized shares of Common Stock, and each holder shall
      have the right to pursue all remedies available at law or in equity (including
      degree of specific performance and/or injunctive relief).

    1.4  Method
      of Conversion.

     

    (a)  Mechanics
      of Conversion.
      Subject
      to Section 1.1, this Note may be converted by the Holder in whole or in part
      at
      any time from time to time after the Issue Date, by (A) submitting to the
      Borrower a Notice of Conversion (by facsimile or other reasonable means of
      communication dispatched on the Conversion Date prior to 6:00 p.m., New York,
      New York time) and (B) subject to Section 1.4(b), surrendering this Note at
      the principal office of the Borrower. 

     

    (b)  Surrender
      of Note Upon Conversion.
      Notwithstanding
      anything to the contrary set forth herein, upon conversion of this Note in
      accordance with the terms hereof, the Holder shall not be required to physically
      surrender this Note to the Borrower unless the entire unpaid principal amount
      of
      this Note is so converted. The Holder and the Borrower shall maintain records
      showing the principal amount so converted and the dates of such conversions
      or
      shall use such other method, reasonably satisfactory to the Holder and the
      Borrower, so as not to require physical surrender of this Note upon each such
      conversion. In the event of any dispute or discrepancy, such records of the
      Borrower shall be controlling and determinative in the absence of manifest
      error. Notwithstanding the foregoing, if any portion of this Note is converted
      as aforesaid, the Holder may not transfer this Note unless the Holder first
      physically surrenders this Note to the Borrower, whereupon the Borrower will
      forthwith issue and deliver upon the order of the Holder a new Note of like
      tenor, registered as the Holder (upon payment by the Holder of any applicable
      transfer taxes) may request, representing in the aggregate the remaining unpaid
      principal amount of this Note. The Holder and any assignee, by acceptance of
      this Note, acknowledge and agree that, by reason of the provisions of this
      paragraph, following conversion of a portion of this Note, the unpaid and
      unconverted principal amount of this Note represented by this Note may be less
      than the amount stated on the face hereof.

     

    (c)  Payment
      of Taxes.
      The
      Borrower shall not be required to pay any tax which may be payable in respect
      of
      any transfer involved in the issue and delivery of shares of Common Stock or
      other securities or property on conversion of this Note in a name other than
      that of the Holder (or in street name), and the Borrower shall not be required
      to issue or deliver any such shares or other securities or property unless
      and
      until the person or persons (other than the Holder or the custodian in whose
      street name such shares are to be held for the Holder’s account) requesting the
      issuance thereof shall have paid to the Borrower the amount of any such tax
      or
      shall have established to the satisfaction of the Borrower that such tax has
      been paid.

     

    (d)  Delivery
      of Common Stock Upon Conversion.
      Upon
      receipt by the Borrower from the Holder of a facsimile transmission (or other
      reasonable means of communication) of a Notice of Conversion meeting the
      requirements for conversion as provided in this Section 1.4, the Borrower shall
      issue and deliver or cause to be issued and delivered to or upon the order
      of
      the Holder certificates for the Common Stock issuable upon such conversion
      within three (3) business days after such receipt (and, solely in the case
      of
      conversion of the entire unpaid principal amount hereof, surrender of this
      Note)
      (such third business day being hereinafter referred to as the “Deadline”)
      in
      accordance with the terms hereof and the Purchase Agreement (including, without
      limitation, in accordance with the requirements of Section 2(g) of the Purchase
      Agreement that certificates for shares of Common Stock issued on or after the
      effective date of the Registration Statement upon conversion of this Note shall
      not bear any restrictive legend).

    (e)  Obligation
      of Borrower to Deliver Common Stock.
      Upon
      receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed
      to
      be the holder of record of the Common Stock issuable upon such conversion,
      the
      outstanding principal amount and the amount of accrued and unpaid interest
      on
      this Note shall be reduced to reflect such conversion, and, unless the Borrower
      defaults on its obligations under this Article I, all rights with respect to
      the
      portion of this Note being so converted shall forthwith terminate except the
      right to receive the Common Stock or other securities, cash or other assets,
      as
      herein provided, on such conversion. If the Holder shall have given a Notice
      of
      Conversion as provided herein, the Borrower’s obligation to issue and deliver
      the certificates for Common Stock shall be absolute and unconditional,
      irrespective of the absence of any action by the Holder to enforce the same,
      any
      waiver or consent with respect to any provision thereof, the recovery of any
      judgment against any person or any action to enforce the same, any failure
      or
      delay in the enforcement of any other obligation of the Borrower to the holder
      of record, or any setoff, counterclaim, recoupment, limitation or termination,
      or any breach or alleged breach by the Holder of any obligation to the Borrower,
      and irrespective of any other circumstance which might otherwise limit such
      obligation of the Borrower to the Holder in connection with such conversion.
      The
      Conversion Date specified in the Notice of Conversion shall be the Conversion
      Date so long as the Notice of Conversion is received by the Borrower before
      6:00
      p.m., New York, New York time, on such date.

     

    (f)  Delivery
      of Common Stock by Electronic Transfer.
      In
      lieu
      of delivering physical certificates representing the Common Stock issuable
      upon
      conversion, provided the Borrower’s transfer agent is participating in the
      Depository Trust Company (“DTC”)
      Fast
      Automated Securities Transfer (“FAST”)
      program, upon request of the Holder and its compliance with the provisions
      contained in Section 1.1 and in this Section 1.4, the Borrower shall use its
      best efforts to cause its transfer agent to electronically transmit the Common
      Stock issuable upon conversion to the Holder by crediting the account of
      Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission
      (“DWAC”)
      system.

     

    (g)  Failure
      to Deliver Common Stock Prior to Deadline.
      Without
      in any way limiting the Holder’s right to pursue other remedies, including
      actual damages and/or equitable relief, the parties agree that if delivery
      of
      the Common Stock issuable upon conversion of this Note is more than two (2)
      business days after the Deadline (other than a failure due to the circumstances
      described in Section 1.3 above, which failure shall be governed by such Section)
      the Borrower shall pay to the Holder $2,000 per day in cash, for each day beyond
      the Deadline that the Borrower fails to deliver such Common Stock. Such cash
      amount shall be paid to Holder by the fifth day of the month following the
      month
      in which it has accrued or, at the option of the Holder (by written notice
      to
      the Borrower by the first day of the month following the month in which it
      has
      accrued), shall be added to the principal amount of this Note, in which event
      interest shall accrue thereon in accordance with the terms of this Note and
      such
      additional principal amount shall be convertible into Common Stock in accordance
      with the terms of this Note.

    1.5  Concerning
      the Shares.
      The
      shares of Common Stock issuable upon conversion of this Note may not be sold
      or
      transferred unless (i) such shares are sold pursuant to an effective
      registration statement under the Act or (ii) the Borrower or its transfer agent
      shall have been furnished with an opinion of counsel (which opinion shall be
      in
      form, substance and scope customary for opinions of counsel in comparable
      transactions) to the effect that the shares to be sold or transferred may be
      sold or transferred pursuant to an exemption from such registration or
      (iii) such shares are sold or transferred pursuant to Rule 144 under the
      Act (or a successor rule) (“Rule
      144”)
      or
      (iv) such shares are transferred to an “affiliate” (as defined in Rule 144) of
      the Borrower who agrees to sell or otherwise transfer the shares only in
      accordance with this Section 1.5 and who is an Accredited Investor (as defined
      in the Purchase Agreement). Except as otherwise provided in the Purchase
      Agreement (and subject to the removal provisions set forth below), until such
      time as the shares of Common Stock issuable upon conversion of this Note have
      been registered under the Act as contemplated by the Registration Rights
      Agreement or otherwise may be sold pursuant to Rule 144 without any restriction
      as to the number of securities as of a particular date that can then be
      immediately sold, each certificate for shares of Common Stock issuable upon
      conversion of this Note that has not been so included in an effective
      registration statement or that has not been sold pursuant to an effective
      registration statement or an exemption that permits removal of the legend,
      shall
      bear a legend substantially in the following form, as appropriate:

     

    “THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED
      OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE
      SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND
      SCOPE
      CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT REGISTRATION
      IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144 OR REGULATION
      S
      UNDER SAID ACT.”

     

    The
      legend set forth above shall be removed and the Borrower shall issue to the
      Holder a new certificate therefor free of any transfer legend if (i) the
      Borrower or its transfer agent shall have received an opinion of counsel, in
      form, substance and scope customary for opinions of counsel in comparable
      transactions, to the effect that a public sale or transfer of such Common Stock
      may be made without registration under the Act and the shares are so sold or
      transferred, (ii) such Holder provides the Borrower or its transfer agent with
      reasonable assurances that the Common Stock issuable upon conversion of this
      Note (to the extent such securities are deemed to have been acquired on the
      same
      date) can be sold pursuant to Rule 144 or (iii) in the case of the Common Stock
      issuable upon conversion of this Note, such security is registered for sale
      by
      the Holder under an effective registration statement filed under the Act or
      otherwise may be sold pursuant to Rule 144 without any restriction as to the
      number of securities as of a particular date that can then be immediately sold.
      Nothing in this Note shall (i) limit the Borrower’s obligation under the
      Registration Rights Agreement or (ii) affect in any way the Holder’s obligations
      to comply with applicable prospectus delivery requirements upon the resale
      of
      the securities referred to herein.

     

    1.6  Effect
      of Certain Events.

     

    (a)  Effect
      of Merger, Consolidation, Etc.
      At the
      option of the Holder, the sale, conveyance or disposition of all or
      substantially all of the assets of the Borrower, the effectuation by the
      Borrower of a transaction or series of related transactions in which more than
      50% of the voting power of the Borrower is disposed of, or the consolidation,
      merger or other business combination of the Borrower with or into any other
      Person (as defined below) or Persons when the Borrower is not the survivor
      shall
      either: (i) be deemed to be an Event of Default (as defined in Article III)
      pursuant to which the Borrower shall be required to pay to the Holder upon
      the
      consummation of and as a condition to such transaction an amount equal to the
      Default Amount (as defined in Article III) or (ii) be treated pursuant to
      Section 1.6(b) hereof. “Person”
shall
      mean any individual, corporation, limited liability company, partnership,
      association, trust or other entity or organization.

    (b)  Adjustment
      Due to Merger, Consolidation, Etc.
      If,
      at
      any time when this Note is issued and outstanding and prior to conversion of
      all
      of the Notes, there shall be any merger, consolidation, exchange of shares,
      recapitalization, reorganization, or other similar event, as a result of which
      shares of Common Stock of the Borrower shall be changed into the same or a
      different number of shares of another class or classes of stock or securities
      of
      the Borrower or another entity, or in case of any sale or conveyance of all
      or
      substantially all of the assets of the Borrower other than in connection with
      a
      plan of complete liquidation of the Borrower, then the Holder of this Note
      shall
      thereafter have the right to receive upon conversion of this Note, upon the
      basis and upon the terms and conditions specified herein and in lieu of the
      shares of Common Stock immediately theretofore issuable upon conversion, such
      stock, securities or assets which the Holder would have been entitled to receive
      in such transaction had this Note been converted in full immediately prior
      to
      such transaction (without regard to any limitations on conversion set forth
      herein), and in any such case appropriate provisions shall be made with respect
      to the rights and interests of the Holder of this Note to the end that the
      provisions hereof (including, without limitation, provisions for adjustment
      of
      the Conversion Price and of the number of shares issuable upon conversion of
      the
      Note) shall thereafter be applicable, as nearly as may be practicable in
      relation to any securities or assets thereafter deliverable upon the conversion
      hereof. The Borrower shall not effect any transaction described in this Section
      1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days
      prior written notice (but in any event at least fifteen (15) days prior written
      notice) of the record date of the special meeting of shareholders to approve,
      or
      if there is no such record date, the consummation of, such merger,
      consolidation, exchange of shares, recapitalization, reorganization or other
      similar event or sale of assets (during which time the Holder shall be entitled
      to convert this Note) and (b) the resulting successor or acquiring entity (if
      not the Borrower) assumes by written instrument the obligations of this Section
      1.6(b). The above provisions shall similarly apply to successive consolidations,
      mergers, sales, transfers or share exchanges.

     

    (c)  Adjustment
      Due to Distribution.
      If
      the
      Borrower shall declare or make any distribution of its assets (or rights to
      acquire its assets) to holders of Common Stock as a dividend, stock repurchase,
      by way of return of capital or otherwise (including any dividend or distribution
      to the Borrower’s shareholders in cash or shares (or rights to acquire shares)
      of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”),
      then
      the Holder of this Note shall be entitled, upon any conversion of this Note
      after the date of record for determining shareholders entitled to such
      Distribution, to receive the amount of such assets which would have been payable
      to the Holder with respect to the shares of Common Stock issuable upon such
      conversion had such Holder been the holder of such shares of Common Stock on
      the
      record date for the determination of shareholders entitled to such
      Distribution.

    (d)  Adjustment
      Due to Dilutive Issuance.
      If, at
      any time when any Notes are issued and outstanding, the Borrower issues or
      sells, or in accordance with this Section 1.6(d) hereof is deemed to have issued
      or sold, any shares of Common Stock for no consideration or for a consideration
      per share (before deduction of reasonable expenses or commissions or
      underwriting discounts or allowances in connection therewith) less than the
      Fixed Conversion Price in effect on the date of such issuance (or deemed
      issuance) of such shares of Common Stock (a “Dilutive
      Issuance”),
      then
      immediately upon the Dilutive Issuance, the Variable Conversion Price will
      be
      reduced to the amount of the consideration per share received by the Borrower
      in
      such Dilutive Issuance; provided
      that
      only one adjustment will be made for each Dilutive Issuance.

     

    The
      Borrower shall be deemed to have issued or sold shares of Common Stock if the
      Borrower in any manner issues or grants any warrants, rights or options (not
      including employee stock option plans), whether or not immediately exercisable,
      to subscribe for or to purchase Common Stock or other securities convertible
      into or exchangeable for Common Stock (“Convertible
      Securities”)
      (such
      warrants, rights and options to purchase Common Stock or Convertible Securities
      are hereinafter referred to as “Options”)
      and
      the price per share for which Common Stock is issuable upon the exercise of
      such
      Options is less than the Variable Conversion Price then in effect, then the
      Variable Conversion Price shall be equal to such price per share. For purposes
      of the preceding sentence, the “price per share for which Common Stock is
      issuable upon the exercise of such Options” is determined by dividing (i) the
      total amount, if any, received or receivable by the Borrower as consideration
      for the issuance or granting of all such Options, plus the minimum aggregate
      amount of additional consideration, if any, payable to the Borrower upon the
      exercise of all such Options, plus, in the case of Convertible Securities
      issuable upon the exercise of such Options, the minimum aggregate amount of
      additional consideration payable upon the conversion or exchange thereof at
      the
      time such Convertible Securities first become convertible or exchangeable,
      by
      (ii) the maximum total number of shares of Common Stock issuable upon the
      exercise of all such Options (assuming full conversion of Convertible
      Securities, if applicable). No further adjustment to the Conversion Price will
      be made upon the actual issuance of such Common Stock upon the exercise of
      such
      Options or upon the conversion or exchange of Convertible Securities issuable
      upon exercise of such Options.

     

    Additionally,
      the Borrower shall be deemed to have issued or sold shares of Common Stock
      if
      the Borrower in any manner issues or sells any Convertible Securities, whether
      or not immediately convertible (other than where the same are issuable upon
      the
      exercise of Options), and the price per share for which Common Stock is issuable
      upon such conversion or exchange is less than the Variable Conversion Price
      then
      in effect, then the Variable Conversion Price shall be equal to such price
      per
      share. For the purposes of the preceding sentence, the “price per share for
      which Common Stock is issuable upon such conversion or exchange” is determined
      by dividing (i) the total amount, if any, received or receivable by the Borrower
      as consideration for the issuance or sale of all such Convertible Securities,
      plus the minimum aggregate amount of additional consideration, if any, payable
      to the Borrower upon the conversion or exchange thereof at the time such
      Convertible Securities first become convertible or exchangeable, by (ii) the
      maximum total number of shares of Common Stock issuable upon the conversion
      or
      exchange of all such Convertible Securities. No further adjustment to the
      Variable Conversion Price will be made upon the actual issuance of such Common
      Stock upon conversion or exchange of such Convertible Securities.

    (e)  Purchase
      Rights.
      If,
      at
      any time when any Notes are issued and outstanding, the Borrower issues any
      convertible securities or rights to purchase stock, warrants, securities or
      other property (the “Purchase
      Rights”)
      pro
      rata to the record holders of any class of Common Stock, then the Holder of
      this
      Note will be entitled to acquire, upon the terms applicable to such Purchase
      Rights, the aggregate Purchase Rights which such Holder could have acquired
      if
      such Holder had held the number of shares of Common Stock acquirable upon
      complete conversion of this Note (without regard to any limitations on
      conversion contained herein) immediately before the date on which a record
      is
      taken for the grant, issuance or sale of such Purchase Rights or, if no such
      record is taken, the date as of which the record holders of Common Stock are
      to
      be determined for the grant, issue or sale of such Purchase Rights.

     

    (f)  Notice
      of Adjustments.
      Upon
      the
      occurrence of each adjustment or readjustment of the Conversion Price as a
      result of the events described in this Section 1.6, the Borrower, at its
      expense, shall promptly compute such adjustment or readjustment and prepare
      and
      furnish to the Holder of a certificate setting forth such adjustment or
      readjustment and showing in detail the facts upon which such adjustment or
      readjustment is based. The Borrower shall, upon the written request at any
      time
      of the Holder, furnish to such Holder a like certificate setting forth (i)
      such
      adjustment or readjustment, (ii) the Conversion Price at the time in effect
      and
      (iii) the number of shares of Common Stock and the amount, if any, of other
      securities or property which at the time would be received upon conversion
      of
      the Note.

     

    1.7  Trading
      Market Limitations.
      Unless
      permitted by the applicable rules and regulations of the principal securities
      market on which the Common Stock is then listed or traded, in no event shall
      the
      Borrower issue upon conversion of or otherwise pursuant to this Note and the
      other Notes issued pursuant to the Purchase Agreement more than the maximum
      number of shares of Common Stock that the Borrower can issue pursuant to any
      rule of the principal United States securities market on which the Common Stock
      is then traded (the “Maximum
      Share Amount”),
      which
      shall be 19.99% of the total shares outstanding on the Closing Date (as defined
      in the Purchase Agreement), subject to equitable adjustment from time to time
      for stock splits, stock dividends, combinations, capital reorganizations and
      similar events relating to the Common Stock occurring after the date hereof.
      Once the Maximum Share Amount has been issued (the date of which is hereinafter
      referred to as the “Maximum
      Conversion Date”),
      if
      the Borrower fails to eliminate any prohibitions under applicable law or the
      rules or regulations of any stock exchange, interdealer quotation system or
      other self-regulatory organization with jurisdiction over the Borrower or any
      of
      its securities on the Borrower’s ability to issue shares of Common Stock in
      excess of the Maximum Share Amount (a “Trading
      Market Prepayment Event”),
      in
      lieu of any further right to convert this Note, and in full satisfaction of
      the
      Borrower’s obligations under this Note, the Borrower shall pay to the Holder,
      within fifteen (15) business days of the Maximum Conversion Date (the
“Trading
      Market Prepayment Date”),
      an
      amount equal to 130% times
      the
sum
      of (a)
      the then outstanding principal amount of this Note immediately following the
      Maximum Conversion Date, plus
      (b)
      accrued and unpaid interest on the unpaid principal amount of this Note to
      the
      Trading Market Prepayment Date, plus
      (c)
      Default Interest, if any, on the amounts referred to in clause (a) and/or (b)
      above, plus
      (d) any
      optional amounts that may be added thereto at the Maximum Conversion Date by
      the
      Holder in accordance with the terms hereof (the then outstanding principal
      amount of this Note immediately following the Maximum Conversion Date,
plus
      the
      amounts referred to in clauses (b), (c) and (d) above shall collectively be
      referred to as the “Remaining
      Convertible Amount”).
      With
      respect to each Holder of Notes, the Maximum Share Amount shall refer to such
      Holder’s pro rata
      share
      thereof determined in accordance with Section 4.8 below. In the event that
      the
      sum of (x) the aggregate number of shares of Common Stock issued upon conversion
      of this Note and the other Notes issued pursuant to the Purchase Agreement
      plus
      (y) the
      aggregate number of shares of Common Stock that remain issuable upon conversion
      of this Note and the other Notes issued pursuant to the Purchase Agreement,
      represents at least one hundred percent (100%) of the Maximum Share Amount
      (the
“Triggering
      Event”),
      the
      Borrower will use its best efforts to seek and obtain Shareholder Approval
      (or
      obtain such other relief as will allow conversions hereunder in excess of the
      Maximum Share Amount) as soon as practicable following the Triggering Event
      and
      before the Maximum Conversion Date. As used herein, “Shareholder
      Approval”
means
      approval by the shareholders of the Borrower to authorize the issuance of the
      full number of shares of Common Stock which would be issuable upon full
      conversion of the then outstanding Notes but for the Maximum Share
      Amount.

    1.8  Status
      as Shareholder.
      Upon
      submission of a Notice of Conversion by a Holder, (i) the shares covered thereby
      (other than the shares, if any, which cannot be issued because their issuance
      would exceed such Holder’s allocated portion of the Reserved Amount or Maximum
      Share Amount) shall be deemed converted into shares of Common Stock and (ii)
      the
      Holder’s rights as a Holder of such converted portion of this Note shall cease
      and terminate, excepting only the right to receive certificates for such shares
      of Common Stock and to any remedies provided herein or otherwise available
      at
      law or in equity to such Holder because of a failure by the Borrower to comply
      with the terms of this Note. Notwithstanding the foregoing, if a Holder has
      not
      received certificates for all shares of Common Stock prior to the tenth (10th)
      business day after the expiration of the Deadline with respect to a conversion
      of any portion of this Note for any reason, then (unless the Holder otherwise
      elects to retain its status as a holder of Common Stock by so notifying the
      Borrower) the Holder shall regain the rights of a Holder of this Note with
      respect to such unconverted portions of this Note and the Borrower shall, as
      soon as practicable, return such unconverted Note to the Holder or, if the
      Note
      has not been surrendered, adjust its records to reflect that such portion of
      this Note has not been converted. In all cases, the Holder shall retain all
      of
      its rights and remedies (including, without limitation, (i) the right to receive
      Conversion Default Payments pursuant to Section 1.3 to the extent required
      thereby for such Conversion Default and any subsequent Conversion Default and
      (ii) the right to have the Conversion Price with respect to subsequent
      conversions determined in accordance with Section 1.3) for the Borrower’s
      failure to convert this Note.

    3.2  Conversion
      and the Shares.

      the
      Holder of the conversion rights of the Holder in accordance with the terms
      of
      this Note (for a period of at least sixty (60) days, if such failure is solely
      as a result of the circumstances governed by Section 1.3 and the Borrower is
      using its best efforts to authorize a sufficient number of shares of Common
      Stock as soon as practicable), fails to transfer or cause its transfer agent
      to
      transfer (electronically or in certificated form) any certificate for shares

      this Note as and when required by this Note or the Registration Rights Agreement
      (or makes any announcement, statement or threat that it does not intend to
      honor
      the obligations described in this paragraph) and any such failure shall continue
      uncured (or any announcement, statement or threat not to honor its obligations
      shall not be rescinded in writing) for ten (10) days after the Borrower shall
      have been notified thereof in writing by the Holder;

     

    3.3  Failure
      to Timely File Registration or Effect Registration.

      Registration Statement within one hundred thirty-five (135) days following
      the
      Investor Demand (as defined in the Registration Rights Agreement) or such
      Registration Statement lapses in effect (or sales cannot otherwise be made
      thereunder effective, whether by reason of the Borrower’s failure to amend or
      supplement the prospectus included therein in accordance with the Registration
      Rights Agreement or otherwise) for more than ten (10) consecutive days or twenty
      (20) days in any twelve month period after the Registration Statement becomes

      period of ten (10) days after written notice thereof to the Borrower from the
      Holder;

     

    3.5  Breach
      of Representations and Warranties.
      Any
      representation or warranty of the Borrower made herein or in any agreement,
      statement or certificate given in writing pursuant hereto or in connection
      herewith (including, without limitation, the Purchase Agreement and the
      Registration Rights Agreement), shall be false or misleading in any material
      respect when made and the breach of which has (or with the passage of time
      will
      have) a material adverse effect on the rights of the Holder with respect to
      this
      Note, the Purchase Agreement or the Registration Rights Agreement;

      for a period of twenty (20) days unless otherwise consented to by the Holder,
      which consent will not be unreasonably withheld;

     

    3.8  Bankruptcy.
      Bankruptcy, insolvency, reorganization or liquidation proceedings or other
      proceedings for relief under any bankruptcy law or any law for the relief of
      debtors shall be instituted by or against the Borrower or any subsidiary of
      the
      Borrower, unless such proceeding shall be stayed within thirty (30)
      days;

     

    3.9  Delisting

      of the OTCBB or an equivalent replacement exchange, the Nasdaq National Market,
      the Nasdaq SmallCap Market, the New York Stock Exchange, or the American Stock

    3.10  Default
      Under Other Notes.
      An Event
      of Default has occurred and is continuing under any of the other Notes issued
      pursuant to the Purchase Agreement,

     

    then,
      upon the occurrence and during the continuation of any Event of Default
      specified in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 3.9, or 3.10, at the option
      of the Holders of a majority of the aggregate principal amount of the
      outstanding Notes issued pursuant to the Purchase Agreement exercisable through
      the delivery of written notice to the Borrower by such Holders (the
“Default
      Notice”),
      and
      upon the occurrence of an Event of Default specified in Section 3.6 or 3.8
      (unless, under Section 3.8, such proceeding shall be stayed within 30 days),
      the
      Notes shall become immediately due and payable and the Borrower shall pay to
      the
      Holder, in full satisfaction of its obligations hereunder, an amount equal
      to
      the greater of (i) 130% times
      the
sum
      of (w)
      the then outstanding principal amount of this Note plus
      (x)
      accrued and unpaid interest on the unpaid principal amount of this Note to
      the
      date of payment (the “Mandatory
      Prepayment Date”)
      plus
      (y)
      Default Interest, if any, on the amounts referred to in clauses (w) and/or
      (x)
plus
      (z) any
      amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof or
      pursuant to Section 2(c) of the Registration Rights Agreement (the then
      outstanding principal amount of this Note to the date of payment plus
      the
      amounts referred to in clauses (x), (y) and (z) shall collectively be known
      as
      the “Default
      Sum”)
      or
      (ii) the “parity value” of the Default Sum to be prepaid, where parity value
      means (a) the highest number of shares of Common Stock issuable upon conversion
      of or otherwise pursuant to such Default Sum in accordance with Article I,
      treating the Trading Day immediately preceding the Mandatory Prepayment Date
      as
      the “Conversion Date” for purposes of determining the lowest applicable
      Conversion Price, unless the Default Event arises as a result of a breach in
      respect of a specific Conversion Date in which case such Conversion Date shall
      be the Conversion Date), multiplied
      by
      (b) the
      highest Closing Price for the Common Stock during the period beginning on the
      date of first occurrence of the Event of Default and ending one day prior to
      the
      Mandatory Prepayment Date (the “Default
      Amount”)
      and
      all other amounts payable hereunder shall immediately become due and payable,
      all without demand, presentment or notice, all of which hereby are expressly
      waived, together with all costs, including, without limitation, legal fees
      and
      expenses, of collection, and the Holder shall be entitled to exercise all other
      rights and remedies available at law or in equity. If the Borrower fails to
      pay
      the Default Amount within five (5) business days of written notice that such
      amount is due and payable, then the Holder shall have the right at any time,
      so
      long as the Borrower remains in default (and so long and to the extent that
      there are sufficient authorized shares), to require the Borrower, upon written
      notice, to immediately issue, in lieu of the Default Amount, the number of
      shares of Common Stock of the Borrower equal to the Default Amount divided
      by
      the Conversion Price then in effect.

      IV.  MISCELLANEOUS

     

    4.1  Failure
      or Indulgence Not Waiver.
      No
      failure or delay on the part of the Holder in the exercise of any power, right
      or privilege hereunder shall operate as a waiver thereof, nor shall any single
      or partial exercise of any such power, right or privilege preclude other or
      further exercise thereof or of any other right, power or privileges. All rights
      and remedies existing hereunder are cumulative to, and not exclusive of, any
      rights or remedies otherwise available.

      Note and any provision hereof may only be amended by an instrument in writing
      signed by the Borrower and the Holder. The term “Note” and all reference
      thereto, as used throughout this instrument, shall mean this instrument (and
      the
      other Notes issued pursuant to the Purchase Agreement) as originally executed,
      or if later amended or supplemented, then as so amended or
      supplemented.

     

    4.4  Assignability.
      This
      Note shall be binding upon the Borrower and its successors and assigns, and
      shall inure to be the benefit of the Holder and its successors and assigns.
      Each
      transferee of this Note must be an “accredited investor” (as defined in Rule
      501(a) of the 1933 Act). Notwithstanding anything in this Note to the contrary,
      this Note may be pledged as collateral in connection with a bona fide
      margin
      account or other lending arrangement.

     

    4.5  Cost
      of Collection.
      If
      default is made in the payment of this Note, the Borrower shall pay the Holder
      hereof costs of collection, including reasonable attorneys’ fees.

     

    4.6  Governing
      Law.
      THIS
      NOTE SHALL BE ENFORCED, GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
      OF
      THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY
      WITHIN SUCH STATE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS. THE
      BORROWER HEREBY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES
      FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK WITH RESPECT TO ANY DISPUTE ARISING
      UNDER THIS NOTE, THE AGREEMENTS ENTERED INTO IN CONNECTION HEREWITH OR THE
      TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. BOTH PARTIES IRREVOCABLY WAIVE
      THE
      DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING.
      BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST
      CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON
      THE PARTY IN ANY SUCH SUIT OR PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER
      PARTY’S RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW. BOTH
      PARTIES AGREE THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR
      PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY
      SUIT ON SUCH JUDGMENT OR IN ANY OTHER LAWFUL MANNER. THE PARTY WHICH DOES NOT
      PREVAIL IN ANY DISPUTE ARISING UNDER THIS NOTE SHALL BE RESPONSIBLE FOR ALL
      FEES
      AND EXPENSES, INCLUDING ATTORNEYS’ FEES, INCURRED BY THE PREVAILING PARTY IN
      CONNECTION WITH SUCH DISPUTE.

    4.7  Certain
      Amounts.
      Whenever
      pursuant to this Note the Borrower is required to pay an amount in excess of
      the
      outstanding principal amount (or the portion thereof required to be paid at
      that
      time) plus accrued and unpaid interest plus Default Interest on such interest,
      the Borrower and the Holder agree that the actual damages to the Holder from
      the
      receipt of cash payment on this Note may be difficult to determine and the
      amount to be so paid by the Borrower represents stipulated damages and not
      a
      penalty and is intended to compensate the Holder in part for loss of the
      opportunity to convert this Note and to earn a return from the sale of shares
      of
      Common Stock acquired upon conversion of this Note at a price in excess of
      the
      price paid for such shares pursuant to this Note. The Borrower and the Holder
      hereby agree that such amount of stipulated damages is not plainly
      disproportionate to the possible loss to the Holder from the receipt of a cash
      payment without the opportunity to convert this Note into shares of Common
      Stock.

     

    4.8  Allocations
      of Maximum Share Amount and Reserved Amount.
      The
      Maximum Share Amount and Reserved Amount shall be allocated pro rata among
      the
      Holders of Notes based on the principal amount of such Notes issued to each
      Holder. Each increase to the Maximum Share Amount and Reserved Amount shall
      be
      allocated pro rata among the Holders of Notes based on the principal amount
      of
      such Notes held by each Holder at the time of the increase in the Maximum Share
      Amount or Reserved Amount. In the event a Holder shall sell or otherwise
      transfer any of such Holder’s Notes, each transferee shall be allocated a pro
      rata portion of such transferor’s Maximum Share Amount and Reserved Amount. Any
      portion of the Maximum Share Amount or Reserved Amount which remains allocated
      to any person or entity which does not hold any Notes shall be allocated to
      the
      remaining Holders of Notes, pro rata based on the principal amount of such
      Notes
      then held by such Holders.

     

    4.9  Damages
      Shares.
      The
      shares of Common Stock that may be issuable to the Holder pursuant to Sections
      1.3 and 1.4(g) hereof and pursuant to Section 2(c) of the Registration Rights
      Agreement (“Damages
      Shares”)
      shall
      be treated as Common Stock issuable upon conversion of this Note for all

    4.10  Denominations.
      At the
      request of the Holder, upon surrender of this Note, the Borrower shall promptly
      issue new Notes in the aggregate outstanding principal amount hereof, in the
      form hereof, in such denominations of at least $50,000 as the Holder shall
      request.

     

    4.11  Purchase
      Agreement.

    4.12  Notice
      of Corporate Events.
      Except
      as otherwise provided below, the Holder of this Note shall have no rights as
      a
      Holder of Common Stock unless and only to the extent that it converts this
      Note
      into Common Stock. The Borrower shall provide the Holder with prior notification
      of any meeting of the Borrower’s shareholders (and copies of proxy materials and
      other information sent to shareholders). In the event of any taking by the
      Borrower of a record of its shareholders for the purpose of determining
      shareholders who are entitled to receive payment of any dividend or other
      distribution, any right to subscribe for, purchase or otherwise acquire
      (including by way of merger, consolidation, reclassification or
      recapitalization) any share of any class or any other securities or property,
      or
      to receive any other right, or for the purpose of determining shareholders
      who
      are entitled to vote in connection with any proposed sale, lease or conveyance
      of all or substantially all of the assets of the Borrower or any proposed
      liquidation, dissolution or winding up of the Borrower, the Borrower shall
      mail
      a notice to the Holder, at least twenty (20) days prior to the record date
      specified therein (or thirty (30) days prior to the consummation of the
      transaction or event, whichever is earlier), of the date on which any such
      record is to be taken for the purpose of such dividend, distribution, right
      or
      other event, and a brief statement regarding the amount and character of such
      dividend, distribution, right or other event to the extent known at such time.
      The Borrower shall make a public announcement of any event requiring
      notification to the Holder hereunder substantially simultaneously with the
      notification to the Holder in accordance with the terms of this Section
      4.12.

     

    4.13  Remedies.
      The
      Borrower acknowledges that a breach by it of its obligations hereunder will
      cause irreparable harm to the Holder, by vitiating the intent and purpose of
      the
      transaction contemplated hereby. Accordingly, the Borrower acknowledges that
      the
      remedy at law for a breach of its obligations under this Note will be inadequate
      and agrees, in the event of a breach or threatened breach by the Borrower of
      the
      provisions of this Note, that the Holder shall be entitled, in addition to
      all
      other available remedies at law or in equity, and in addition to the penalties
      assessable herein, to an injunction or injunctions restraining, preventing
      or
      curing any breach of this Note and to enforce specifically the terms and
      provisions thereof, without the necessity of showing economic loss and without
      any bond or other security being required.

    5.1  Call
      Option.
      Notwithstanding anything to the contrary contained in this Article V, so long
      as
(i) no
      Event of Default or Trading Market Prepayment Event shall have occurred and
      be
      continuing, (ii) the
      Borrower has a sufficient number of authorized shares of Common Stock reserved
      for issuance upon full conversion of the Notes, then at any time after the
      Issue
      Date, and (iii) the
      Common Stock is trading at or below $.30 per share, the Borrower shall have
      the
      right, exercisable on not less than ten (10) Trading Days prior written notice
      to the Holders of the Notes (which notice may not be sent to the Holders of
      the
      Notes until the Borrower is permitted to prepay the Notes pursuant to this
      Section 5.1), to prepay all of the outstanding Notes in accordance with this
      Section 5.1. Any notice of prepayment hereunder (an “Optional
      Prepayment”)
      shall
      be delivered to the Holders of the Notes at their registered addresses appearing
      on the books and records of the Borrower and shall state (1) that the Borrower
      is exercising its right to prepay all of the Notes issued on the Issue Date
      and
      (2) the date of prepayment (the “Optional
      Prepayment Notice”).
      On
      the date fixed for prepayment (the “Optional
      Prepayment Date”),
      the
      Borrower shall make payment of the Optional Prepayment Amount (as defined below)
      to or upon the order of the Holders as specified by the Holders in writing
      to
      the Borrower at least one (1) business day prior to the Optional Prepayment
      Date. If the Borrower exercises its right to prepay the Notes, the Borrower
      shall make payment to the holders of an amount in cash (the “Optional
      Prepayment Amount”)
      equal
      to either (i) 125% (for prepayments occurring within thirty (30) days of
      the Issue Date), (ii) 135% for prepayments occurring between thirty-one
      (31) and sixty (60) days of the Issue Date, or (iii) 145% (for prepayments
      occurring after the sixtieth (60th)
      day
      following the Issue Date), multiplied by the sum of (w) the then outstanding
      principal amount of this Note plus
      (x) accrued and unpaid interest on the unpaid principal amount of this Note
      to the Optional Prepayment Date plus
      (y)
      Default Interest, if any, on the amounts referred to in clauses (w) and (x)
      plus
      (z) any
      amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof or
      pursuant to Section 2(c) of the Registration Rights Agreement (the then
      outstanding principal amount of this Note to the date of payment plus
      the
      amounts referred to in clauses (x), (y) and (z) shall collectively be known
      as
      the “Optional
      Prepayment Sum”).
      Notwithstanding notice of an Optional Prepayment, the Holders shall at all
      times
      prior to the Optional Prepayment Date maintain the right to convert all or
      any
      portion of the Notes in accordance with Article I and any portion of Notes
      so
      converted after receipt of an Optional Prepayment Notice and prior to the
      Optional Prepayment Date set forth in such notice and payment of the aggregate
      Optional Prepayment Amount shall be deducted from the principal amount of Notes
      which are otherwise subject to prepayment pursuant to such notice. If the
      Borrower delivers an Optional Prepayment Notice and fails to pay the Optional
      Prepayment Amount due to the Holders of the Notes within two (2) business days
      following the Optional Prepayment Date, the Borrower shall forever forfeit
      its
      right to redeem the Notes pursuant to this Section 5.1.

     

    5.2  Partial
      Call Option.
      Notwithstanding anything to the contrary contained in this Article V, in the
      event that the Average Daily Price of the Common Stock, as reported by the
      Reporting Service, for each day of the month ending on any Determination Date
      is
      below the Initial Market Price, the Borrower may, at its option, prepay a
      portion of the outstanding principal amount of the Notes equal to 104% of the
      principal amount hereof divided by thirty-six (36) plus one month’s interest.
      The term “Initial
      Market Price”
      means
      shall mean the volume weighted average price of the Common Stock for the five
      (5) Trading Days immediately preceding the Closing which is $.30.

    FOR
      VALUE RECEIVED,

      hereby promises to pay to the order of AJW PARTNERS, LLC or registered assigns
      (the “Holder”)
      the

      and
      to pay interest on the unpaid principal balance hereof at the rate of eight
      percent (8%) (the “Interest
      Rate”)
      per
      annum from October 31, 2006 (the “Issue
      Date”)
      until
      the same becomes due and payable, whether at maturity or upon acceleration
      or by
      prepayment or otherwise. Any amount of principal or interest on this Note which
      is not paid when due shall bear interest at the rate of fifteen percent (15%)

      shall hereafter give to the Borrower by written notice made in accordance with
      the provisions of this Note. Whenever any amount expressed to be due by the
      terms of this Note is due on any day which is not a business day, the same
      shall
      instead be due on the next succeeding day which is a business day and, in the
      case of any interest payment date which is not the date on which this Note
      is
      paid in full, the extension of the due date thereof shall not be taken into
      account for purposes of determining the amount of interest due on such date.
      As
      used in this Note, the term “business day” shall mean any day other than a
      Saturday, Sunday or a day on which commercial banks in the city of New York,

      thereof and shall not be subject to preemptive rights or other similar rights
      of
      shareholders of the Borrower and will not impose personal liability upon the
      holder thereof. The obligations of the Borrower under this Note shall be secured

      each dated October 31, 2006 by and between the Borrower and the
      Holder.

     

    The
      following terms shall apply to this Note:

     

    ARTICLE
      I. CONVERSION
      RIGHTS

     

    1.1 Conversion
      Right.
      The
      Holder shall have the right from time to time, and at any time on or prior
      to
      the earlier of (i) the Maturity Date and (ii) the date of payment of the Default
      Amount (as defined in Article III) pursuant to Section 1.6(a) or Article III,
      the Optional Prepayment Amount (as defined in Section 5.1 or any payments
      pursuant to Section 1.7, each in respect of the remaining outstanding principal
      amount of this Note to convert all or any part of the outstanding and unpaid
      principal amount of this Note into fully paid and non-assessable shares of
      Common Stock, as such Common Stock exists on the Issue Date, or any shares
      of
      capital stock or other securities of the Borrower into which such Common Stock
      shall hereafter be changed or reclassified at the conversion price (the
“Conversion
      Price”)
      determined as provided herein (a “Conversion”);
      provided,
      however,
      that in
      no event shall the Holder be entitled to convert any portion of this Note in
      excess of that portion of this Note upon conversion of which the sum of (1)
      the
      number of shares of Common Stock beneficially owned by the Holder and its
      affiliates (other than shares of Common Stock which may be deemed beneficially
      owned through the ownership of the unconverted portion of the Notes or the
      unexercised or unconverted portion of any other security of the Borrower
      (including, without limitation, the warrants issued by the Borrower pursuant
      to
      the Purchase Agreement) subject to a limitation on conversion or exercise
      analogous to the limitations contained herein) and (2) the number of shares
      of
      Common Stock issuable upon the conversion of the portion of this Note with
      respect to which the determination of this proviso is being made, would result
      in beneficial ownership by the Holder and its affiliates of more than 4.99%
      of
      the outstanding shares of Common Stock and provided further
      that the
      Holder shall not be entitled to convert any portion of this Note during any
      month immediately succeeding a Determination Date on which the Borrower
      exercises its prepayment option pursuant to Section 5.2 of this Note. For
      purposes of the proviso to 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 Regulations 13D-G thereunder, except
      as
      otherwise provided in clause (1) of such proviso. The number of shares of Common
      Stock to be issued upon each conversion of this Note shall be determined by
      dividing the Conversion Amount (as defined below) by the applicable Conversion
      Price then in effect on the date specified in the notice of conversion, in
      the
      form attached hereto as Exhibit A (the “Notice
      of Conversion”),
      delivered to the Borrower by the Holder in accordance with Section 1.4 below;
      provided that the Notice of Conversion is submitted by facsimile (or by other
      means resulting in, or reasonably expected to result in, notice) to the Borrower
      before 6:00 p.m., New York, New York time on such conversion date (the
“Conversion
      Date”).
      The
      term “Conversion
      Amount”
means,
      with respect to any conversion of this Note, the sum of (1) the principal amount
      of this Note to be converted in such conversion plus
      (2)
      accrued and unpaid interest, if any, on such principal amount at the interest
      rates provided in this Note to the Conversion Date, provided, however, that
      the
      Company shall have the right to pay any or all interest in cash plus
      (3)
      Default Interest, if any, on the amounts referred to in the immediately
      preceding clauses (1) and/or (2) plus
      (4) at
      the Holder’s option, any amounts owed to the Holder pursuant to Sections 1.3 and
      1.4(g) hereof or pursuant to Section 2(c) of that certain Registration Rights
      Agreement, dated as of October 31, 2006, executed in connection with the initial
      issuance of this Note and the other Notes issued on the Issue Date (the
“Registration
      Rights Agreement”).
      The
      term “Determination
      Date” means
      the
      last business day of each month after the Issue Date.

    1.2 Conversion
      Price.

     

    (a) Calculation
      of Conversion Price.
      The
      Conversion Price shall be the Variable Conversion Price (as defined herein)
      (subject, in each case, to equitable adjustments for stock splits, stock
      dividends or rights offerings by the Borrower relating to the Borrower’s
      securities or the securities of any subsidiary of the Borrower, combinations,
      recapitalization, reclassifications, extraordinary distributions and similar
      events). The “Variable
      Conversion Price”
shall
      mean the Applicable Percentage (as defined herein) multiplied by the Market
      Price (as defined herein). “Market
      Price”
means
      the average of the lowest three (3) Trading Prices (as defined below) for the
      Common Stock during the twenty (20) Trading Day period ending one Trading Day
      prior to the date the Conversion Notice is sent by the Holder to the Borrower
      via facsimile (the “Conversion
      Date”).
      “Trading
      Price”
means,
      for any security as of any date, the intraday trading price on the
      Over-the-Counter Bulletin Board (the “OTCBB”)
      as
      reported by a reliable reporting service (“Reporting
      Service”)
      mutually acceptable to Borrower and Holder and hereafter designated by Holders
      of a majority in interest of the Notes and the Borrower or, if the OTCBB is
      not
      the principal trading market for such security, the intraday trading price
      of
      such security on the principal securities exchange or trading market where
      such
      security is listed or traded or, if no intraday trading price of such security
      is available in any of the foregoing manners, the average of the intraday
      trading prices of any market makers for such security that are listed in the
      “pink sheets” by the National Quotation Bureau, Inc. If the Trading Price cannot
      be calculated for such security on such date in the manner provided above,
      the
      Trading Price shall be the fair market value as mutually determined by the
      Borrower and the holders of a majority in interest of the Notes being converted
      for which the calculation of the Trading Price is required in order to determine
      the Conversion Price of such Notes. “Trading
      Day”
shall
      mean any day on which the Common Stock is traded for any period on the OTCBB,
      or
      on the principal securities exchange or other securities market on which the
      Common Stock is then being traded. “Applicable
      Percentage”
shall
      mean 60.0%.

     

    (b) Conversion
      Price During Major Announcements.
      Notwithstanding
      anything contained in Section 1.2(a) to the contrary, in the event the Borrower
      (i) makes a public announcement that it intends to consolidate or merge with
      any
      other corporation (other than a merger in which the Borrower is the surviving
      or
      continuing corporation and its capital stock is unchanged) or sell or transfer
      all or substantially all of the assets of the Borrower or (ii) any person,
      group
      or entity (including the Borrower) publicly announces a tender offer to purchase
      50% or more of the Borrower’s Common Stock (or any other takeover scheme) (the
      date of the announcement referred to in clause (i) or (ii) is hereinafter
      referred to as the “Announcement
      Date”),
      then
      the Conversion Price shall, effective upon the Announcement Date and continuing
      through the Adjusted Conversion Price Termination Date (as defined below),
      be
      equal to the lower of (x) the Conversion Price which would have been applicable
      for a Conversion occurring on the Announcement Date and (y) the Conversion
      Price
      that would otherwise be in effect. From and after the Adjusted Conversion Price
      Termination Date, the Conversion Price shall be determined as set forth in
      this
      Section 1.2(a). For purposes hereof, “Adjusted
      Conversion Price Termination Date”
shall
      mean, with respect to any proposed transaction or tender offer (or takeover
      scheme) for which a public announcement as contemplated by this Section 1.2(b)
      has been made, the date upon which the Borrower (in the case of clause (i)
      above) or the person, group or entity (in the case of clause (ii) above)
      consummates or publicly announces the termination or abandonment of the proposed
      transaction or tender offer (or takeover scheme) which caused this Section
      1.2(b) to become operative.

    1.3 Authorized
      Shares.
      Subject
      to Stockholder Approval (as such term is defined in Section 4(n) of the
      Securities Purchase Agreement), the Borrower covenants that during the period
      the conversion right exists, the Borrower will reserve from its authorized
      and
      unissued Common Stock a sufficient number of shares, free from preemptive
      rights, to provide for the issuance of Common Stock upon the full conversion
      of
      this Note and the other Notes issued pursuant to the Purchase Agreement. The
      Borrower is required at all times to have authorized and reserved two times
      the
      number of shares that is actually issuable upon full conversion of the Notes
      (based on the Conversion Price of the Notes or the Exercise Price of the
      Warrants in effect from time to time) (the “Reserved
      Amount”).
      The
      Reserved Amount shall be increased from time to time in accordance with the
      Borrower’s obligations pursuant to Section 4(h) of the Purchase Agreement. The
      Borrower represents that upon issuance, such shares will be duly and validly
      issued, fully paid and non-assessable. In addition, if the Borrower shall issue
      any securities or make any change to its capital structure which would change
      the number of shares of Common Stock into which the Notes shall be convertible
      at the then current Conversion Price, the Borrower shall at the same time make
      proper provision so that thereafter there shall be a sufficient number of shares
      of Common Stock authorized and reserved, free from preemptive rights, for
      conversion of the outstanding Notes. The Borrower (i) acknowledges that it
      has
      irrevocably instructed its transfer agent to issue certificates for the Common
      Stock issuable upon conversion of this Note, and (ii) agrees that its
      issuance of this Note shall constitute full authority to its officers and agents
      who are charged with the duty of executing stock certificates to execute and
      issue the necessary certificates for shares of Common Stock in accordance with
      the terms and conditions of this Note.

     

    If,
      at
      any time a Holder of this Note submits a Notice of Conversion, and the Borrower
      does not have sufficient authorized but unissued shares of Common Stock
      available to effect such conversion in accordance with the provisions of this
      Article I (a “Conversion
      Default”),
      subject to Section 4.8, the Borrower shall issue to the Holder all of the shares
      of Common Stock which are then available to effect such conversion. The portion
      of this Note which the Holder included in its Conversion Notice and which
      exceeds the amount which is then convertible into available shares of Common
      Stock (the “Excess
      Amount”)
      shall,
      notwithstanding anything to the contrary contained herein, not be convertible
      into Common Stock in accordance with the terms hereof until (and at the Holder’s
      option at any time after) the date additional shares of Common Stock are
      authorized by the Borrower to permit such conversion, at which time the
      Conversion Price in respect thereof shall be the lesser of (i) the Conversion
      Price on the Conversion Default Date (as defined below) and (ii) the Conversion
      Price on the Conversion Date thereafter elected by the Holder in respect
      thereof. In addition, the Borrower shall pay to the Holder payments
      (“Conversion
      Default Payments”)
      for a
      Conversion Default in the amount of (x) the sum
      of
      (1) the
      then outstanding principal amount of this Note plus
      (2)
      accrued and unpaid interest on the unpaid principal amount of this Note through
      the Authorization Date (as defined below) plus
      (3)
      Default Interest, if any, on the amounts referred to in clauses (1) and/or
      (2),
multiplied
      by
      (y) .24,
multiplied
      by
      (z)
      (N/365), where N = the number of days from the day the holder submits a Notice
      of Conversion giving rise to a Conversion Default (the “Conversion
      Default Date”)
      to the
      date (the “Authorization
      Date”)
      that
      the Borrower authorizes a sufficient number of shares of Common Stock to effect
      conversion of the full outstanding principal balance of this Note. The Borrower
      shall use its best efforts to authorize a sufficient number of shares of Common
      Stock as soon as practicable following the earlier of (i) such time that the
      Holder notifies the Borrower or that the Borrower otherwise becomes aware that
      there are or likely will be insufficient authorized and unissued shares to
      allow
      full conversion thereof and (ii) a Conversion Default. The Borrower shall send
      notice to the Holder of the authorization of additional shares of Common Stock,
      the Authorization Date and the amount of Holder’s accrued Conversion Default
      Payments. The accrued Conversion Default Payments for each calendar month shall
      be paid in cash or shall be convertible into Common Stock (at such time as
      there
      are sufficient authorized shares of Common Stock) at the applicable Conversion
      Price, at the Borrower’s option, as follows:

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    (a) In
      the
      event Holder elects to take such payment in cash, cash payment shall be made
      to
      Holder by the fifth (5th)
      day of
      the month following the month in which it has accrued; and

     

    (b) In
      the
      event Holder elects to take such payment in Common Stock, the Holder may convert
      such payment amount into Common Stock at the Conversion Price (as in effect
      at
      the time of conversion) at any time after the fifth day of the month following
      the month in which it has accrued in accordance with the terms of this Article
      I
      (so long as there is then a sufficient number of authorized shares of Common
      Stock).

     

    The
      Holder’s election shall be made in writing to the Borrower at any time prior to
      6:00 p.m., New York, New York time, on the third day of the month following
      the
      month in which Conversion Default payments have accrued. If no election is
      made,
      the Holder shall be deemed to have elected to receive cash. Nothing herein
      shall
      limit the Holder’s right to pursue actual damages (to the extent in excess of
      the Conversion Default Payments) for the Borrower’s failure to maintain a
      sufficient number of authorized shares of Common Stock, and each holder shall
      have the right to pursue all remedies available at law or in equity (including
      degree of specific performance and/or injunctive relief).

    1.4 Method
      of Conversion.

     

    (a) Mechanics
      of Conversion.
      Subject
      to Section 1.1, this Note may be converted by the Holder in whole or in part
      at
      any time from time to time after the Issue Date, by (A) submitting to the
      Borrower a Notice of Conversion (by facsimile or other reasonable means of
      communication dispatched on the Conversion Date prior to 6:00 p.m., New York,
      New York time) and (B) subject to Section 1.4(b), surrendering this Note at
      the principal office of the Borrower. 

     

    (b) Surrender
      of Note Upon Conversion.
      Notwithstanding
      anything to the contrary set forth herein, upon conversion of this Note in
      accordance with the terms hereof, the Holder shall not be required to physically
      surrender this Note to the Borrower unless the entire unpaid principal amount
      of
      this Note is so converted. The Holder and the Borrower shall maintain records
      showing the principal amount so converted and the dates of such conversions
      or
      shall use such other method, reasonably satisfactory to the Holder and the
      Borrower, so as not to require physical surrender of this Note upon each such
      conversion. In the event of any dispute or discrepancy, such records of the
      Borrower shall be controlling and determinative in the absence of manifest
      error. Notwithstanding the foregoing, if any portion of this Note is converted
      as aforesaid, the Holder may not transfer this Note unless the Holder first
      physically surrenders this Note to the Borrower, whereupon the Borrower will
      forthwith issue and deliver upon the order of the Holder a new Note of like
      tenor, registered as the Holder (upon payment by the Holder of any applicable
      transfer taxes) may request, representing in the aggregate the remaining unpaid
      principal amount of this Note. The Holder and any assignee, by acceptance of
      this Note, acknowledge and agree that, by reason of the provisions of this
      paragraph, following conversion of a portion of this Note, the unpaid and
      unconverted principal amount of this Note represented by this Note may be less
      than the amount stated on the face hereof.

     

    (c) Payment
      of Taxes.
      The
      Borrower shall not be required to pay any tax which may be payable in respect
      of
      any transfer involved in the issue and delivery of shares of Common Stock or
      other securities or property on conversion of this Note in a name other than
      that of the Holder (or in street name), and the Borrower shall not be required
      to issue or deliver any such shares or other securities or property unless
      and
      until the person or persons (other than the Holder or the custodian in whose
      street name such shares are to be held for the Holder’s account) requesting the
      issuance thereof shall have paid to the Borrower the amount of any such tax
      or
      shall have established to the satisfaction of the Borrower that such tax has
      been paid.

     

    (d) Delivery
      of Common Stock Upon Conversion.
      Upon
      receipt by the Borrower from the Holder of a facsimile transmission (or other
      reasonable means of communication) of a Notice of Conversion meeting the
      requirements for conversion as provided in this Section 1.4, the Borrower shall
      issue and deliver or cause to be issued and delivered to or upon the order
      of
      the Holder certificates for the Common Stock issuable upon such conversion
      within three (3) business days after such receipt (and, solely in the case
      of
      conversion of the entire unpaid principal amount hereof, surrender of this
      Note)
      (such third business day being hereinafter referred to as the “Deadline”)
      in
      accordance with the terms hereof and the Purchase Agreement (including, without
      limitation, in accordance with the requirements of Section 2(g) of the Purchase
      Agreement that certificates for shares of Common Stock issued on or after the
      effective date of the Registration Statement upon conversion of this Note shall
      not bear any restrictive legend).

     

    
      
        
        

      

      
        6

        
          

        

      

      
        
        

      

    

    (e) Obligation
      of Borrower to Deliver Common Stock.
      Upon
      receipt by the Borrower of a Notice of Conversion, the Holder shall be deemed
      to
      be the holder of record of the Common Stock issuable upon such conversion,
      the
      outstanding principal amount and the amount of accrued and unpaid interest
      on
      this Note shall be reduced to reflect such conversion, and, unless the Borrower
      defaults on its obligations under this Article I, all rights with respect to
      the
      portion of this Note being so converted shall forthwith terminate except the
      right to receive the Common Stock or other securities, cash or other assets,
      as
      herein provided, on such conversion. If the Holder shall have given a Notice
      of
      Conversion as provided herein, the Borrower’s obligation to issue and deliver
      the certificates for Common Stock shall be absolute and unconditional,
      irrespective of the absence of any action by the Holder to enforce the same,
      any
      waiver or consent with respect to any provision thereof, the recovery of any
      judgment against any person or any action to enforce the same, any failure
      or
      delay in the enforcement of any other obligation of the Borrower to the holder
      of record, or any setoff, counterclaim, recoupment, limitation or termination,
      or any breach or alleged breach by the Holder of any obligation to the Borrower,
      and irrespective of any other circumstance which might otherwise limit such
      obligation of the Borrower to the Holder in connection with such conversion.
      The
      Conversion Date specified in the Notice of Conversion shall be the Conversion
      Date so long as the Notice of Conversion is received by the Borrower before
      6:00
      p.m., New York, New York time, on such date.

     

    (f) Delivery
      of Common Stock by Electronic Transfer.
      In
      lieu
      of delivering physical certificates representing the Common Stock issuable
      upon
      conversion, provided the Borrower’s transfer agent is participating in the
      Depository Trust Company (“DTC”)
      Fast
      Automated Securities Transfer (“FAST”)
      program, upon request of the Holder and its compliance with the provisions
      contained in Section 1.1 and in this Section 1.4, the Borrower shall use its
      best efforts to cause its transfer agent to electronically transmit the Common
      Stock issuable upon conversion to the Holder by crediting the account of
      Holder’s Prime Broker with DTC through its Deposit Withdrawal Agent Commission
      (“DWAC”)
      system.

     

    (g) Failure
      to Deliver Common Stock Prior to Deadline.
      Without
      in any way limiting the Holder’s right to pursue other remedies, including
      actual damages and/or equitable relief, the parties agree that if delivery
      of
      the Common Stock issuable upon conversion of this Note is more than two (2)
      business days after the Deadline (other than a failure due to the circumstances
      described in Section 1.3 above, which failure shall be governed by such Section)
      the Borrower shall pay to the Holder $2,000 per day in cash, for each day beyond
      the Deadline that the Borrower fails to deliver such Common Stock. Such cash
      amount shall be paid to Holder by the fifth day of the month following the
      month
      in which it has accrued or, at the option of the Holder (by written notice
      to
      the Borrower by the first day of the month following the month in which it
      has
      accrued), shall be added to the principal amount of this Note, in which event
      interest shall accrue thereon in accordance with the terms of this Note and
      such
      additional principal amount shall be convertible into Common Stock in accordance
      with the terms of this Note.

     

    1.5 Concerning
      the Shares.
      The
      shares of Common Stock issuable upon conversion of this Note may not be sold
      or
      transferred unless (i) such shares are sold pursuant to an effective
      registration statement under the Act or (ii) the Borrower or its transfer agent
      shall have been furnished with an opinion of counsel (which opinion shall be
      in
      form, substance and scope customary for opinions of counsel in comparable
      transactions) to the effect that the shares to be sold or transferred may be
      sold or transferred pursuant to an exemption from such registration or
      (iii) such shares are sold or transferred pursuant to Rule 144 under the
      Act (or a successor rule) (“Rule
      144”)
      or
      (iv) such shares are transferred to an “affiliate” (as defined in Rule 144) of
      the Borrower who agrees to sell or otherwise transfer the shares only in
      accordance with this Section 1.5 and who is an Accredited Investor (as defined
      in the Purchase Agreement). Except as otherwise provided in the Purchase
      Agreement (and subject to the removal provisions set forth below), until such
      time as the shares of Common Stock issuable upon conversion of this Note have
      been registered under the Act as contemplated by the Registration Rights
      Agreement or otherwise may be sold pursuant to Rule 144 without any restriction
      as to the number of securities as of a particular date that can then be
      immediately sold, each certificate for shares of Common Stock issuable upon
      conversion of this Note that has not been so included in an effective
      registration statement or that has not been sold pursuant to an effective
      registration statement or an exemption that permits removal of the legend,
      shall
      bear a legend substantially in the following form, as appropriate:

     

    
      
        
        

      

      
        7

        
          

        

      

      
        
        

      

    

    “THE
      SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
      SECURITIES ACT OF 1933, AS AMENDED. THE SECURITIES MAY NOT BE SOLD, TRANSFERRED
      OR ASSIGNED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE
      SECURITIES UNDER SAID ACT, OR AN OPINION OF COUNSEL IN FORM, SUBSTANCE AND
      SCOPE
      CUSTOMARY FOR OPINIONS OF COUNSEL IN COMPARABLE TRANSACTIONS, THAT REGISTRATION
      IS NOT REQUIRED UNDER SAID ACT UNLESS SOLD PURSUANT TO RULE 144 OR REGULATION
      S
      UNDER SAID ACT.”

     

    The
      legend set forth above shall be removed and the Borrower shall issue to the
      Holder a new certificate therefor free of any transfer legend if (i) the
      Borrower or its transfer agent shall have received an opinion of counsel, in
      form, substance and scope customary for opinions of counsel in comparable
      transactions, to the effect that a public sale or transfer of such Common Stock
      may be made without registration under the Act and the shares are so sold or
      transferred, (ii) such Holder provides the Borrower or its transfer agent with
      reasonable assurances that the Common Stock issuable upon conversion of this
      Note (to the extent such securities are deemed to have been acquired on the
      same
      date) can be sold pursuant to Rule 144 or (iii) in the case of the Common Stock
      issuable upon conversion of this Note, such security is registered for sale
      by
      the Holder under an effective registration statement filed under the Act or
      otherwise may be sold pursuant to Rule 144 without any restriction as to the
      number of securities as of a particular date that can then be immediately sold.
      Nothing in this Note shall (i) limit the Borrower’s obligation under the
      Registration Rights Agreement or (ii) affect in any way the Holder’s obligations
      to comply with applicable prospectus delivery requirements upon the resale
      of
      the securities referred to herein.

     

    1.6 Effect
      of Certain Events.

     

    (a) Effect
      of Merger, Consolidation, Etc.
      At the
      option of the Holder, the sale, conveyance or disposition of all or
      substantially all of the assets of the Borrower, the effectuation by the
      Borrower of a transaction or series of related transactions in which more than
      50% of the voting power of the Borrower is disposed of, or the consolidation,
      merger or other business combination of the Borrower with or into any other
      Person (as defined below) or Persons when the Borrower is not the survivor
      shall
      either: (i) be deemed to be an Event of Default (as defined in Article III)
      pursuant to which the Borrower shall be required to pay to the Holder upon
      the
      consummation of and as a condition to such transaction an amount equal to the
      Default Amount (as defined in Article III) or (ii) be treated pursuant to
      Section 1.6(b) hereof. “Person”
shall
      mean any individual, corporation, limited liability company, partnership,
      association, trust or other entity or organization.

    (b) Adjustment
      Due to Merger, Consolidation, Etc.
      If,
      at
      any time when this Note is issued and outstanding and prior to conversion of
      all
      of the Notes, there shall be any merger, consolidation, exchange of shares,
      recapitalization, reorganization, or other similar event, as a result of which
      shares of Common Stock of the Borrower shall be changed into the same or a
      different number of shares of another class or classes of stock or securities
      of
      the Borrower or another entity, or in case of any sale or conveyance of all
      or
      substantially all of the assets of the Borrower other than in connection with
      a
      plan of complete liquidation of the Borrower, then the Holder of this Note
      shall
      thereafter have the right to receive upon conversion of this Note, upon the
      basis and upon the terms and conditions specified herein and in lieu of the
      shares of Common Stock immediately theretofore issuable upon conversion, such
      stock, securities or assets which the Holder would have been entitled to receive
      in such transaction had this Note been converted in full immediately prior
      to
      such transaction (without regard to any limitations on conversion set forth
      herein), and in any such case appropriate provisions shall be made with respect
      to the rights and interests of the Holder of this Note to the end that the
      provisions hereof (including, without limitation, provisions for adjustment
      of
      the Conversion Price and of the number of shares issuable upon conversion of
      the
      Note) shall thereafter be applicable, as nearly as may be practicable in
      relation to any securities or assets thereafter deliverable upon the conversion
      hereof. The Borrower shall not effect any transaction described in this Section
      1.6(b) unless (a) it first gives, to the extent practicable, thirty (30) days
      prior written notice (but in any event at least fifteen (15) days prior written
      notice) of the record date of the special meeting of shareholders to approve, or
      if there is no such record date, the consummation of, such merger,
      consolidation, exchange of shares, recapitalization, reorganization or other
      similar event or sale of assets (during which time the Holder shall be entitled
      to convert this Note) and (b) the resulting successor or acquiring entity (if
      not the Borrower) assumes by written instrument the obligations of this Section
      1.6(b). The above provisions shall similarly apply to successive consolidations,
      mergers, sales, transfers or share exchanges.

     

    (c) Adjustment
      Due to Distribution.
      If
      the
      Borrower shall declare or make any distribution of its assets (or rights to
      acquire its assets) to holders of Common Stock as a dividend, stock repurchase,
      by way of return of capital or otherwise (including any dividend or distribution
      to the Borrower’s shareholders in cash or shares (or rights to acquire shares)
      of capital stock of a subsidiary (i.e., a spin-off)) (a “Distribution”),
      then
      the Holder of this Note shall be entitled, upon any conversion of this Note
      after the date of record for determining shareholders entitled to such
      Distribution, to receive the amount of such assets which would have been payable
      to the Holder with respect to the shares of Common Stock issuable upon such
      conversion had such Holder been the holder of such shares of Common Stock on
      the
      record date for the determination of shareholders entitled to such
      Distribution.

    (d) Adjustment
      Due to Dilutive Issuance.
      If, at
      any time when any Notes are issued and outstanding, the Borrower issues or
      sells, or in accordance with this Section 1.6(d) hereof is deemed to have issued
      or sold, any shares of Common Stock for no consideration or for a consideration
      per share (before deduction of reasonable expenses or commissions or
      underwriting discounts or allowances in connection therewith) less than the
      Fixed Conversion Price in effect on the date of such issuance (or deemed
      issuance) of such shares of Common Stock (a “Dilutive
      Issuance”),
      then
      immediately upon the Dilutive Issuance, the Variable Conversion Price will
      be
      reduced to the amount of the consideration per share received by the Borrower
      in
      such Dilutive Issuance; provided
      that
      only one adjustment will be made for each Dilutive Issuance.

     

    The
      Borrower shall be deemed to have issued or sold shares of Common Stock if the
      Borrower in any manner issues or grants any warrants, rights or options (not
      including employee stock option plans), whether or not immediately exercisable,
      to subscribe for or to purchase Common Stock or other securities convertible
      into or exchangeable for Common Stock (“Convertible
      Securities”)
      (such
      warrants, rights and options to purchase Common Stock or Convertible Securities
      are hereinafter referred to as “Options”)
      and
      the price per share for which Common Stock is issuable upon the exercise of
      such
      Options is less than the Variable Conversion Price then in effect, then the
      Variable Conversion Price shall be equal to such price per share. For purposes
      of the preceding sentence, the “price per share for which Common Stock is
      issuable upon the exercise of such Options” is determined by dividing (i) the
      total amount, if any, received or receivable by the Borrower as consideration
      for the issuance or granting of all such Options, plus the minimum aggregate
      amount of additional consideration, if any, payable to the Borrower upon the
      exercise of all such Options, plus, in the case of Convertible Securities
      issuable upon the exercise of such Options, the minimum aggregate amount of
      additional consideration payable upon the conversion or exchange thereof at
      the
      time such Convertible Securities first become convertible or exchangeable,
      by
      (ii) the maximum total number of shares of Common Stock issuable upon the
      exercise of all such Options (assuming full conversion of Convertible
      Securities, if applicable). No further adjustment to the Conversion Price will
      be made upon the actual issuance of such Common Stock upon the exercise of
      such
      Options or upon the conversion or exchange of Convertible Securities issuable
      upon exercise of such Options.

     

    Additionally,
      the Borrower shall be deemed to have issued or sold shares of Common Stock
      if
      the Borrower in any manner issues or sells any Convertible Securities, whether
      or not immediately convertible (other than where the same are issuable upon
      the
      exercise of Options), and the price per share for which Common Stock is issuable
      upon such conversion or exchange is less than the Variable Conversion Price
      then
      in effect, then the Variable Conversion Price shall be equal to such price
      per
      share. For the purposes of the preceding sentence, the “price per share for
      which Common Stock is issuable upon such conversion or exchange” is determined
      by dividing (i) the total amount, if any, received or receivable by the Borrower
      as consideration for the issuance or sale of all such Convertible Securities,
      plus the minimum aggregate amount of additional consideration, if any, payable
      to the Borrower upon the conversion or exchange thereof at the time such
      Convertible Securities first become convertible or exchangeable, by (ii) the
      maximum total number of shares of Common Stock issuable upon the conversion
      or
      exchange of all such Convertible Securities. No further adjustment to the
      Variable Conversion Price will be made upon the actual issuance of such Common
      Stock upon conversion or exchange of such Convertible Securities.

    (e) Purchase
      Rights.
      If,
      at
      any time when any Notes are issued and outstanding, the Borrower issues any
      convertible securities or rights to purchase stock, warrants, securities or
      other property (the “Purchase
      Rights”)
      pro
      rata to the record holders of any class of Common Stock, then the Holder of
      this
      Note will be entitled to acquire, upon the terms applicable to such Purchase
      Rights, the aggregate Purchase Rights which such Holder could have acquired
      if
      such Holder had held the number of shares of Common Stock acquirable upon
      complete conversion of this Note (without regard to any limitations on
      conversion contained herein) immediately before the date on which a record
      is
      taken for the grant, issuance or sale of such Purchase Rights or, if no such
      record is taken, the date as of which the record holders of Common Stock are
      to
      be determined for the grant, issue or sale of such Purchase Rights.

     

    (f) Notice
      of Adjustments.
      Upon
      the
      occurrence of each adjustment or readjustment of the Conversion Price as a
      result of the events described in this Section 1.6, the Borrower, at its
      expense, shall promptly compute such adjustment or readjustment and prepare
      and
      furnish to the Holder of a certificate setting forth such adjustment or
      readjustment and showing in detail the facts upon which such adjustment or
      readjustment is based. The Borrower shall, upon the written request at any
      time
      of the Holder, furnish to such Holder a like certificate setting forth (i)
      such
      adjustment or readjustment, (ii) the Conversion Price at the time in effect
      and
      (iii) the number of shares of Common Stock and the amount, if any, of other
      securities or property which at the time would be received upon conversion
      of
      the Note.

     

    1.7 Trading
      Market Limitations.
      Unless
      permitted by the applicable rules and regulations of the principal securities
      market on which the Common Stock is then listed or traded, in no event shall
      the
      Borrower issue upon conversion of or otherwise pursuant to this Note and the
      other Notes issued pursuant to the Purchase Agreement more than the maximum
      number of shares of Common Stock that the Borrower can issue pursuant to any
      rule of the principal United States securities market on which the Common Stock
      is then traded (the “Maximum
      Share Amount”),
      which
      shall be 19.99% of the total shares outstanding on the Closing Date (as defined
      in the Purchase Agreement), subject to equitable adjustment from time to time
      for stock splits, stock dividends, combinations, capital reorganizations and
      similar events relating to the Common Stock occurring after the date hereof.
      Once the Maximum Share Amount has been issued (the date of which is hereinafter
      referred to as the “Maximum
      Conversion Date”),
      if
      the Borrower fails to eliminate any prohibitions under applicable law or the
      rules or regulations of any stock exchange, interdealer quotation system or
      other self-regulatory organization with jurisdiction over the Borrower or any
      of
      its securities on the Borrower’s ability to issue shares of Common Stock in
      excess of the Maximum Share Amount (a “Trading
      Market Prepayment Event”),
      in
      lieu of any further right to convert this Note, and in full satisfaction of
      the
      Borrower’s obligations under this Note, the Borrower shall pay to the Holder,
      within fifteen (15) business days of the Maximum Conversion Date (the
“Trading
      Market Prepayment Date”),
      an
      amount equal to 130% times
      the
sum
      of (a)
      the then outstanding principal amount of this Note immediately following the
      Maximum Conversion Date, plus
      (b)
      accrued and unpaid interest on the unpaid principal amount of this Note to
      the
      Trading Market Prepayment Date, plus
      (c)
      Default Interest, if any, on the amounts referred to in clause (a) and/or (b)
      above, plus
      (d) any
      optional amounts that may be added thereto at the Maximum Conversion Date by
      the
      Holder in accordance with the terms hereof (the then outstanding principal
      amount of this Note immediately following the Maximum Conversion Date,
plus
      the
      amounts referred to in clauses (b), (c) and (d) above shall collectively be
      referred to as the “Remaining
      Convertible Amount”).
      With
      respect to each Holder of Notes, the Maximum Share Amount shall refer to such
      Holder’s pro rata
      share
      thereof determined in accordance with Section 4.8 below. In the event that
      the
      sum of (x) the aggregate number of shares of Common Stock issued upon conversion
      of this Note and the other Notes issued pursuant to the Purchase Agreement
      plus
      (y) the
      aggregate number of shares of Common Stock that remain issuable upon conversion
      of this Note and the other Notes issued pursuant to the Purchase Agreement,
      represents at least one hundred percent (100%) of the Maximum Share Amount
      (the
“Triggering
      Event”),
      the
      Borrower will use its best efforts to seek and obtain Shareholder Approval
      (or
      obtain such other relief as will allow conversions hereunder in excess of the
      Maximum Share Amount) as soon as practicable following the Triggering Event
      and
      before the Maximum Conversion Date. As used herein, “Shareholder
      Approval”
means
      approval by the shareholders of the Borrower to authorize the issuance of the
      full number of shares of Common Stock which would be issuable upon full
      conversion of the then outstanding Notes but for the Maximum Share
      Amount.

    1.8 Status
      as Shareholder.
      Upon
      submission of a Notice of Conversion by a Holder, (i) the shares covered thereby
      (other than the shares, if any, which cannot be issued because their issuance
      would exceed such Holder’s allocated portion of the Reserved Amount or Maximum
      Share Amount) shall be deemed converted into shares of Common Stock and (ii)
      the
      Holder’s rights as a Holder of such converted portion of this Note shall cease
      and terminate, excepting only the right to receive certificates for such shares
      of Common Stock and to any remedies provided herein or otherwise available
      at
      law or in equity to such Holder because of a failure by the Borrower to comply
      with the terms of this Note. Notwithstanding the foregoing, if a Holder has
      not
      received certificates for all shares of Common Stock prior to the tenth (10th)
      business day after the expiration of the Deadline with respect to a conversion
      of any portion of this Note for any reason, then (unless the Holder otherwise
      elects to retain its status as a holder of Common Stock by so notifying the
      Borrower) the Holder shall regain the rights of a Holder of this Note with
      respect to such unconverted portions of this Note and the Borrower shall, as
      soon as practicable, return such unconverted Note to the Holder or, if the
      Note
      has not been surrendered, adjust its records to reflect that such portion of
      this Note has not been converted. In all cases, the Holder shall retain all
      of
      its rights and remedies (including, without limitation, (i) the right to receive
      Conversion Default Payments pursuant to Section 1.3 to the extent required
      thereby for such Conversion Default and any subsequent Conversion Default and
      (ii) the right to have the Conversion Price with respect to subsequent
      conversions determined in accordance with Section 1.3) for the Borrower’s
      failure to convert this Note.

      securities) on shares of capital stock other than dividends on shares of Common
      Stock solely in the form of additional shares of Common Stock or (b) directly
      or
      indirectly or through any subsidiary make any other payment or distribution
      in
      respect of its capital stock except for distributions pursuant to any
      shareholders’ rights plan which is approved by a majority of the Borrower’s
      disinterested directors.

      in any one transaction or series of related transactions any shares of capital
      stock of the Borrower or any warrants, rights or options to purchase or acquire
      any such shares.

      financial institutions incurred in the ordinary course of business or (c)
      borrowings, the proceeds of which shall be used to repay this Note.

     

    2.4 Sale
      of Assets.
      So long
      as the Borrower shall have any obligation under this Note, the Borrower shall
      not, without the Holder’s written consent, sell, lease or otherwise dispose of
      any significant portion of its assets outside the ordinary course of business.
      Any consent to the disposition of any assets may be conditioned on a specified
      use of the proceeds of disposition.

     

    2.5 Advances
      and Loans.
      So long
      as the Borrower shall have any obligation under this Note, the Borrower shall

      Liabilities.
      So long
      as the Borrower shall have any obligation under this Note, the Borrower shall
      not, without the Holder’s written consent, which shall not be unreasonably
      withheld, assume, guarantee, endorse, contingently agree to purchase or
      otherwise become liable upon the obligation of any person, firm, partnership,
      joint venture or corporation, except by the endorsement of negotiable

      the following events of default (each, an “Event
      of Default”)
      shall
      occur:

     

    3.1 Failure
      to Pay Principal or Interest.
      The
      Borrower fails to pay the principal hereof or interest thereon when due on
      this
      Note, whether at maturity, upon a Trading Market Prepayment Event pursuant
      to
      Section 1.7, upon acceleration or otherwise;

    3.2 Conversion
      and the Shares.
      The
      Borrower fails to issue shares of Common Stock to the Holder (or announces
      or
      threatens that it will not honor its obligation to do so) upon exercise by
      the
      Holder of the conversion rights of the Holder in accordance with the terms
      of
      this Note (for a period of at least sixty (60) days, if such failure is solely
      as a result of the circumstances governed by Section 1.3 and the Borrower is
      using its best efforts to authorize a sufficient number of shares of Common
      Stock as soon as practicable), fails to transfer or cause its transfer agent
      to
      transfer (electronically or in certificated form) any certificate for shares
      of
      Common Stock issued to the Holder upon conversion of or otherwise pursuant
      to
      this Note as and when required by this Note or the Registration Rights
      Agreement, or fails to remove any restrictive legend (or to withdraw any stop
      transfer instructions in respect thereof) on any certificate for any shares
      of
      Common Stock issued to the Holder upon conversion of or otherwise pursuant
      to
      this Note as and when required by this Note or the Registration Rights Agreement
      (or makes any announcement, statement or threat that it does not intend to
      honor
      the obligations described in this paragraph) and any such failure shall continue
      uncured (or any announcement, statement or threat not to honor its obligations
      shall not be rescinded in writing) for ten (10) days after the Borrower shall
      have been notified thereof in writing by the Holder;

     

    3.3 Failure
      to Timely File Registration or Effect Registration.
      The
      Borrower fails to file the Registration Statement within sixty (60) days
      following an Investor Demand (as set forth in the Registration Rights Agreement)
      or obtain effectiveness with the Securities and Exchange Commission of the
      Registration Statement within one hundred thirty-five (135) days following
      the
      Investor Demand (as defined in the Registration Rights Agreement) or such
      Registration Statement lapses in effect (or sales cannot otherwise be made
      thereunder effective, whether by reason of the Borrower’s failure to amend or
      supplement the prospectus included therein in accordance with the Registration
      Rights Agreement or otherwise) for more than ten (10) consecutive days or twenty

    3.10 Default
      Under Other Notes.
      An Event
      of Default has occurred and is continuing under any of the other Notes issued
      pursuant to the Purchase Agreement,

     

    then,
      upon the occurrence and during the continuation of any Event of Default
      specified in Section 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 3.9, or 3.10, at the option
      of the Holders of a majority of the aggregate principal amount of the
      outstanding Notes issued pursuant to the Purchase Agreement exercisable through
      the delivery of written notice to the Borrower by such Holders (the
“Default
      Notice”),
      and
      upon the occurrence of an Event of Default specified in Section 3.6 or 3.8
      (unless, under Section 3.8, such proceeding shall be stayed within 30 days),
      the
      Notes shall become immediately due and payable and the Borrower shall pay to
      the
      Holder, in full satisfaction of its obligations hereunder, an amount equal
      to
      the greater of (i) 130% times
      the
sum
      of (w)
      the then outstanding principal amount of this Note plus
      (x)
      accrued and unpaid interest on the unpaid principal amount of this Note to
      the
      date of payment (the “Mandatory
      Prepayment Date”)
      plus
      (y)
      Default Interest, if any, on the amounts referred to in clauses (w) and/or
      (x)
plus
      (z) any
      amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof or
      pursuant to Section 2(c) of the Registration Rights Agreement (the then
      outstanding principal amount of this Note to the date of payment plus
      the
      amounts referred to in clauses (x), (y) and (z) shall collectively be known
      as
      the “Default
      Sum”)
      or
      (ii) the “parity value” of the Default Sum to be prepaid, where parity value
      means (a) the highest number of shares of Common Stock issuable upon conversion
      of or otherwise pursuant to such Default Sum in accordance with Article I,
      treating the Trading Day immediately preceding the Mandatory Prepayment Date
      as
      the “Conversion Date” for purposes of determining the lowest applicable
      Conversion Price, unless the Default Event arises as a result of a breach in
      respect of a specific Conversion Date in which case such Conversion Date shall
      be the Conversion Date), multiplied
      by
      (b) the
      highest Closing Price for the Common Stock during the period beginning on the
      date of first occurrence of the Event of Default and ending one day prior to
      the
      Mandatory Prepayment Date (the “Default
      Amount”)
      and
      all other amounts payable hereunder shall immediately become due and payable,
      all without demand, presentment or notice, all of which hereby are expressly
      waived, together with all costs, including, without limitation, legal fees
      and
      expenses, of collection, and the Holder shall be entitled to exercise all other
      rights and remedies available at law or in equity. If the Borrower fails to
      pay
      the Default Amount within five (5) business days of written notice that such
      amount is due and payable, then the Holder shall have the right at any time,
      so
      long as the Borrower remains in default (and so long and to the extent that
      there are sufficient authorized shares), to require the Borrower, upon written
      notice, to immediately issue, in lieu of the Default Amount, the number of
      shares of Common Stock of the Borrower equal to the Default Amount divided
      by
      the Conversion Price then in effect.

      or Indulgence Not Waiver.
      No
      failure or delay on the part of the Holder in the exercise of any power, right
      or privilege hereunder shall operate as a waiver thereof, nor shall any single

      Note shall be binding upon the Borrower and its successors and assigns, and
      shall inure to be the benefit of the Holder and its successors and assigns.
      Each
      transferee of this Note must be an “accredited investor” (as defined in Rule

    4.6 Governing
      Law.
      THIS
      NOTE SHALL BE ENFORCED, GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
      OF
      THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED ENTIRELY
      WITHIN SUCH STATE, WITHOUT REGARD TO THE PRINCIPLES OF CONFLICT OF LAWS. THE
      BORROWER HEREBY SUBMITS TO THE EXCLUSIVE JURISDICTION OF THE UNITED STATES
      FEDERAL COURTS LOCATED IN NEW YORK, NEW YORK WITH RESPECT TO ANY DISPUTE ARISING
      UNDER THIS NOTE, THE AGREEMENTS ENTERED INTO IN CONNECTION HEREWITH OR THE
      TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. BOTH PARTIES IRREVOCABLY WAIVE
      THE
      DEFENSE OF AN INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH SUIT OR PROCEEDING.
      BOTH PARTIES FURTHER AGREE THAT SERVICE OF PROCESS UPON A PARTY MAILED BY FIRST
      CLASS MAIL SHALL BE DEEMED IN EVERY RESPECT EFFECTIVE SERVICE OF PROCESS UPON
      THE PARTY IN ANY SUCH SUIT OR PROCEEDING. NOTHING HEREIN SHALL AFFECT EITHER
      PARTY’S RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW. BOTH
      PARTIES AGREE THAT A FINAL NON-APPEALABLE JUDGMENT IN ANY SUCH SUIT OR
      PROCEEDING SHALL BE CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY
      SUIT ON SUCH JUDGMENT OR IN ANY OTHER LAWFUL MANNER. THE PARTY WHICH DOES NOT

    4.7 Certain
      Amounts.
      Whenever
      pursuant to this Note the Borrower is required to pay an amount in excess of
      the
      outstanding principal amount (or the portion thereof required to be paid at
      that
      time) plus accrued and unpaid interest plus Default Interest on such interest,
      the Borrower and the Holder agree that the actual damages to the Holder from
      the
      receipt of cash payment on this Note may be difficult to determine and the
      amount to be so paid by the Borrower represents stipulated damages and not
      a
      penalty and is intended to compensate the Holder in part for loss of the
      opportunity to convert this Note and to earn a return from the sale of shares
      of
      Common Stock acquired upon conversion of this Note at a price in excess of
      the
      price paid for such shares pursuant to this Note. The Borrower and the Holder
      hereby agree that such amount of stipulated damages is not plainly
      disproportionate to the possible loss to the Holder from the receipt of a cash
      payment without the opportunity to convert this Note into shares of Common
      Stock.

     

    4.8 Allocations
      of Maximum Share Amount and Reserved Amount.
      The
      Maximum Share Amount and Reserved Amount shall be allocated pro rata among
      the
      Holders of Notes based on the principal amount of such Notes issued to each
      Holder. Each increase to the Maximum Share Amount and Reserved Amount shall
      be
      allocated pro rata among the Holders of Notes based on the principal amount
      of
      such Notes held by each Holder at the time of the increase in the Maximum Share
      Amount or Reserved Amount. In the event a Holder shall sell or otherwise
      transfer any of such Holder’s Notes, each transferee shall be allocated a pro
      rata portion of such transferor’s Maximum Share Amount and Reserved Amount. Any
      portion of the Maximum Share Amount or Reserved Amount which remains allocated
      to any person or entity which does not hold any Notes shall be allocated to
      the
      remaining Holders of Notes, pro rata based on the principal amount of such
      Notes
      then held by such Holders.

     

    4.9 Damages
      Shares.
      The
      shares of Common Stock that may be issuable to the Holder pursuant to Sections
      1.3 and 1.4(g) hereof and pursuant to Section 2(c) of the Registration Rights
      Agreement (“Damages
      Shares”)
      shall
      be treated as Common Stock issuable upon conversion of this Note for all
      purposes hereof and shall be subject to all of the limitations and afforded
      all
      of the rights of the other shares of Common Stock issuable hereunder, including
      without limitation, the right to be included in the Registration Statement
      filed
      pursuant to the Registration Rights Agreement. For purposes of calculating
      interest payable on the outstanding principal amount hereof, except as otherwise
      provided herein, amounts convertible into Damages Shares (“Damages
      Amounts”)
      shall
      not bear interest but must be converted prior to the conversion of any
      outstanding principal amount hereof, until the outstanding Damages Amounts
      is
      zero.

    4.10 Denominations.
      At the
      request of the Holder, upon surrender of this Note, the Borrower shall promptly
      issue new Notes in the aggregate outstanding principal amount hereof, in the
      form hereof, in such denominations of at least $50,000 as the Holder shall
      request.

     

    4.11 Purchase
      Agreement.
      By its
      acceptance of this Note, each Holder agrees to be bound by the applicable terms
      of the Purchase Agreement.

     

    4.12 Notice
      of Corporate Events.
      Except
      as otherwise provided below, the Holder of this Note shall have no rights as
      a
      Holder of Common Stock unless and only to the extent that it converts this
      Note
      into Common Stock. The Borrower shall provide the Holder with prior notification
      of any meeting of the Borrower’s shareholders (and copies of proxy materials and
      other information sent to shareholders). In the event of any taking by the
      Borrower of a record of its shareholders for the purpose of determining
      shareholders who are entitled to receive payment of any dividend or other
      distribution, any right to subscribe for, purchase or otherwise acquire
      (including by way of merger, consolidation, reclassification or
      recapitalization) any share of any class or any other securities or property,
      or
      to receive any other right, or for the purpose of determining shareholders
      who
      are entitled to vote in connection with any proposed sale, lease or conveyance
      of all or substantially all of the assets of the Borrower or any proposed
      liquidation, dissolution or winding up of the Borrower, the Borrower shall
      mail
      a notice to the Holder, at least twenty (20) days prior to the record date
      specified therein (or thirty (30) days prior to the consummation of the
      transaction or event, whichever is earlier), of the date on which any such
      record is to be taken for the purpose of such dividend, distribution, right
      or
      other event, and a brief statement regarding the amount and character of such
      dividend, distribution, right or other event to the extent known at such time.
      The Borrower shall make a public announcement of any event requiring
      notification to the Holder hereunder substantially simultaneously with the
      notification to the Holder in accordance with the terms of this Section
      4.12.

     

    4.13 Remedies.
      The
      Borrower acknowledges that a breach by it of its obligations hereunder will
      cause irreparable harm to the Holder, by vitiating the intent and purpose of
      the
      transaction contemplated hereby. Accordingly, the Borrower acknowledges that
      the
      remedy at law for a breach of its obligations under this Note will be inadequate
      and agrees, in the event of a breach or threatened breach by the Borrower of
      the
      provisions of this Note, that the Holder shall be entitled, in addition to
      all
      other available remedies at law or in equity, and in addition to the penalties
      assessable herein, to an injunction or injunctions restraining, preventing
      or
      curing any breach of this Note and to enforce specifically the terms and
      provisions thereof, without the necessity of showing economic loss and without
      any bond or other security being required.

    5.1 Call
      Option.
      Notwithstanding anything to the contrary contained in this Article V, so long
      as
(i) no
      Event of Default or Trading Market Prepayment Event shall have occurred and
      be
      continuing, (ii) the
      Borrower has a sufficient number of authorized shares of Common Stock reserved
      for issuance upon full conversion of the Notes, then at any time after the
      Issue
      Date, and (iii) the
      Common Stock is trading at or below $.30 per share, the Borrower shall have
      the
      right, exercisable on not less than ten (10) Trading Days prior written notice
      to the Holders of the Notes (which notice may not be sent to the Holders of
      the
      Notes until the Borrower is permitted to prepay the Notes pursuant to this
      Section 5.1), to prepay all of the outstanding Notes in accordance with this
      Section 5.1. Any notice of prepayment hereunder (an “Optional
      Prepayment”)
      shall
      be delivered to the Holders of the Notes at their registered addresses appearing
      on the books and records of the Borrower and shall state (1) that the Borrower
      is exercising its right to prepay all of the Notes issued on the Issue Date
      and
      (2) the date of prepayment (the “Optional
      Prepayment Notice”).
      On
      the date fixed for prepayment (the “Optional
      Prepayment Date”),
      the
      Borrower shall make payment of the Optional Prepayment Amount (as defined below)
      to or upon the order of the Holders as specified by the Holders in writing
      to
      the Borrower at least one (1) business day prior to the Optional Prepayment
      Date. If the Borrower exercises its right to prepay the Notes, the Borrower
      shall make payment to the holders of an amount in cash (the “Optional
      Prepayment Amount”)
      equal
      to either (i) 125% (for prepayments occurring within thirty (30) days of
      the Issue Date), (ii) 135% for prepayments occurring between thirty-one
      (31) and sixty (60) days of the Issue Date, or (iii) 145% (for prepayments
      occurring after the sixtieth (60th)
      day
      following the Issue Date), multiplied by the sum of (w) the then outstanding
      principal amount of this Note plus
      (x) accrued and unpaid interest on the unpaid principal amount of this Note
      to the Optional Prepayment Date plus
      (y)
      Default Interest, if any, on the amounts referred to in clauses (w) and (x)
      plus
      (z) any
      amounts owed to the Holder pursuant to Sections 1.3 and 1.4(g) hereof or
      pursuant to Section 2(c) of the Registration Rights Agreement (the then
      outstanding principal amount of this Note to the date of payment plus
      the
      amounts referred to in clauses (x), (y) and (z) shall collectively be known
      as
      the “Optional
      Prepayment Sum”).
      Notwithstanding notice of an Optional Prepayment, the Holders shall at all
      times
      prior to the Optional Prepayment Date maintain the right to convert all or
      any
      portion of the Notes in accordance with Article I and any portion of Notes
      so
      converted after receipt of an Optional Prepayment Notice and prior to the
      Optional Prepayment Date set forth in such notice and payment of the aggregate
      Optional Prepayment Amount shall be deducted from the principal amount of Notes
      which are otherwise subject to prepayment pursuant to such notice. If the
      Borrower delivers an Optional Prepayment Notice and fails to pay the Optional
      Prepayment Amount due to the Holders of the Notes within two (2) business days
      following the Optional Prepayment Date, the Borrower shall forever forfeit
      its
      right to redeem the Notes pursuant to this Section 5.1.

     

    5.2 Partial
      Call Option.
      Notwithstanding anything to the contrary contained in this Article V, in the
      event that the Average Daily Price of the Common Stock, as reported by the
      Reporting Service, for each day of the month ending on any Determination Date
      is
      below the Initial Market Price, the Borrower may, at its option, prepay a
      portion of the outstanding principal amount of the Notes equal to 104% of the
      principal amount hereof divided by thirty-six (36) plus one month’s interest.
      The term “Initial
      Market Price”
      means
      shall mean the volume weighted average price of the Common Stock for the five
      (5) Trading Days immediately preceding the Closing which is $.30.
