        earlier of the first February 28, May 31, August 31 or November 30 following
        the
        date hereof.

      


      Prepayment.
        The
        principal amount of this Note may be prepaid by the Company at any time without
        penalty upon thirty (30) days prior written notice to the Holder; provided
        that
        if such written notice is provided at anytime that the Principal Amount may

        section hereof, such prepayment shall be permissible only with the prior
        written
        consent of the holder hereof.

       

      Optional
        Conversion.
        Beginning _____________, 200_, and ending on the Maturity Date, the Principal
        Amount outstanding under this Note may be converted at the option of the
        Holder
        into shares of Common Stock of the Company at a conversion rate of one share
        per
        $.96 of the Principal Amount (the “Conversion Shares”). Such optional conversion
        may be for the whole or any part of the Principal Amount of this Note. The
        Holder may exercise his conversion rights hereunder by delivering a conversion
        notice to the Company substantially in the form of Exhibit A
        hereto.

      

        Reorganization,
          Reclassification, Consolidation, Merger or Sale, etc.  

         

        (i) If
          the
          Company at any time subdivides (by any stock split, stock dividend,
          recapitalization or otherwise) its class of outstanding shares of the Common
          Stock into a greater number of shares, the conversion rate in effect immediately
          prior to such subdivision will be proportionately reduced, and if the Company
          at
          any time combines (by reverse stock split or otherwise) one or more classes
          of
          its outstanding shares of its Common Stock, the conversion rate in effect
          immediately prior to such combination will be proportionately increased
          concurrently with the effectiveness of such event.

         

        (ii) Any
          capital reorganization, reclassification, consolidation, merger or sale
          of all
          or substantially all of the Company’s assets to another person which is effected
          in such a way that holders of Common Stock are entitled to receive (either
          directly or upon subsequent liquidation) stock, securities or assets with
          respect to or in exchange for Common Stock is referred to herein as an
“Organic
          Change.” Prior to the consummation of any Organic Change, the Company will make
          appropriate provisions to insure that the Holder will thereafter have the
          right
          upon subsequent conversion of the Principal Amount to acquire and receive
          such
          shares of stock, securities or assets as such Holder would have received
          in
          connection with such Organic Change if such Holder had converted the Principal
          Amount hereof immediately prior to such Organic Change. The Company will
          not
          effect any such consolidation, merger or sale, unless prior to the consummation
          thereof, the successor Company (if other than the Company) resulting from
          consolidation or merger or the Company purchasing such assets assumes by
          written
          instrument the obligation to deliver to the Holder such shares of stock,
          securities or assets as, in accordance with the foregoing provisions, such
          holder may be entitled to acquire.

         

        Stock
          to be Reserved.

          Company will at all times reserve and keep available out of its authorized
          Common Stock or its treasury shares, solely for the purpose of issue upon
          the
          conversion of the Principal Amount of the Note as herein provided, such
          number
          of shares of Common Stock as shall then be issuable upon the conversion
          of then
          outstanding Principal Amount of this Note. The Company covenants that all
          shares
          of Common Stock which shall be so issued shall be duly and validly issued
          and
          fully paid and nonassessable and free from all liens and charges with respect
          to
          the issue thereof.
