      Exchange Ratio"), each share of Series D Preferred Stock issued and
      outstanding immediately prior to the Effective Date shall be converted
      into the right to receive 0.683023 of a share of Parent Common Stock and
      each share of Series CC Preferred Stock outstanding immediately prior to
      the Effective Date shall be cancelled. All such shares of Company Common
      Stock, Series D Preferred Stock and Series CC Preferred Stock shall no
      longer be outstanding and shall automatically be cancelled and shall cease
      to exist, and each certificate previously evidencing any such shares shall
      thereafter represent the right to receive, upon the surrender of such
      certificate in accordance with the provisions of Section 3 hereof,
      certificates evidencing such number of shares of Parent Common Stock,
      respectively, into which such shares of Company Common Stock were
      converted. The holders of such certificates previously evidencing shares
      of Company Common Stock or Series D Preferred Stock outstanding
      immediately prior to the Effective Date shall cease to have any rights
      with respect to such shares of Company Common Stock or Series D Preferred
      Stock, as the case may be, except as otherwise provided herein or by law;"

      15,000,000 shares of the Series CC Preferred Stock and 19,531,247 shares
      of the Series D Preferred Stock are issued and outstanding. Other than the
      exercise or conversion of outstanding options or warrants to purchase
      Company Common Stock, the foregoing shares represent all of the shares of
      the Company's capital stock that will be issued and outstanding as of the
      Closing."
