        (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

          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

          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.

          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
