      has
      been executed by Borrower on the date set forth above (the "Effective
      Date")
      pursuant to the Note and Warrant Purchase Agreement entered into as of the
      date
      hereof between Lender and Borrower (the "Purchase

      Capitalized terms used but not defined herein shall have the meanings assigned
      to such terms in the Purchase Agreement.

     

    1. Interest.
      This
      Note shall bear interest at a
      rate
      of 10%
      per
      annum (“Interest
      Rate”)
      from
      the Effective Date and continuing until payment in full of this
      Note.

     

    2. Maturity
      Date.
      All or
      any portion of this Note, all accrued interest hereon and all other sums due
      hereunder, shall be due and payable on demand by Lender on January 2,
      2008
      (the “Maturity
      Date”),
      subject to the
      up to
three
      extensions of the Maturity Date set forth in the Purchase Agreement.


     

    3. Application
      of Payments.
      

     

    3.1. Except
      as
      otherwise expressly provided herein, payments under this Note shall be applied
      (i) first to the repayment of any sums incurred by Lender for the payment of
      any
      expenses in enforcing the terms of this Note, (ii) then to the payment of
      accrued but unpaid interest due under this Note and (iii) then to the payment
      of
      outstanding principal due under this Note.

     

    3.2. Upon
      payment in full of this Note and applicable accrued and unpaid interest hereon,
      this Note shall be marked "Paid in Full" and returned to Borrower.

     

    4. Waiver
      of Notice.
      Borrower hereby waives diligence, notice, presentment, protest and notice of
      dishonor.


    
      
         

      

      
         

        
          

        

      

      
         

      

    


    5. Optional
      Conversion.
      At any
      time prior to January 2, 2008, upon 10 days prior written notice to Borrower
      (“Conversion
      Date”),
      Lender shall have the right, in its sole discretion, to covert all outstanding
      principal and accrued interest under this Note existing as of close of business
      on the Conversion Date into shares of the Company’s Common Stock (“Common
      Stock”)
      at the
      conversion price set forth below. If Lender elects to convert this Note into
      shares of Common Stock, the number of shares of Common Stock to be issued upon
      such conversion shall be equal to the quotient obtained by dividing (a) the
      outstanding principal and accrued but unpaid interest due on this Note on the
      Conversion Date by (b) $0.65.

     

    6. Transfer.
      This
      Note may be transferred by Lender at any time, provided that such transfer
      complies with applicable securities laws
      and the
      limitations on transfer set forth in Section 6.8 of the Purchase
      Agreement.

     

    7. Events
      of Default.
      The
      occurrence of any of following events (each an "Event
      of Default"),
      not
      cured in any applicable cure period, shall constitute an Event of Default of
      Borrower:

     

    7.1. The
      failure to make when due any payment described in this Note or the Purchase
      Agreement, whether on or after the Maturity Date, by acceleration or otherwise;
      and

     

    7.2. A
      breach
      of any representation, warranty, covenant or other provision of this Note or
      the
      Purchase Agreement, which, if capable of being cured, is not cured within 10
      days following notice thereof to the Company;

     

    7.3. (i)
      The
      application for the appointment of a receiver or custodian for Borrower or
      the
      property of Borrower, (ii) the entry of an order for relief or the filing of
      a
      petition by or against Borrower under the provisions of any bankruptcy or
      insolvency law, (iii) any assignment for the benefit of creditors by or against
      Borrower, or (iv) the insolvency of Borrower.

     

    Upon
      the
      occurrence of any Event of Default that is not cured within any applicable
      cure
      period, if any,
      the
      Lenders that own at least a majority of the aggregate principal amount of all
      notes issued pursuant to the Purchase Agreement, plus all accrued and unpaid
      interest thereon, may elect, by written notice delivered to Borrower, to take
      at
      any time any or all of the following actions: (i)
      declare this Note, and all notes issued pursuant to the Purchase Agreement,
      to
      be forthwith due and payable, whereupon the entire outstanding principal due
      under this Note, together with all accrued and unpaid interest thereon, and
      all
      other cash obligations hereunder, shall become forthwith due and payable,
      without presentment, demand, protest or any other notice of any kind, all of
      which are hereby expressly waived by Borrower, anything contained herein to
      the
      contrary notwithstanding; and (ii) exercise any and all other remedies provided
      hereunder or available at law or in equity.
      In
      addition to the foregoing, Borrower may be required to issue warrants to Lender
      as set forth in Section 2.6 of the Purchase Agreement,
      which
      issuance would not preclude Lender from taking any and all actions whether
      at
      law or equity to enforce its rights.
