      issue is Forty-five million (45,000,000), of which Twenty-Five Million
      (25,000,000) shall be Common Stock and Twenty Million (20,000,000) shall

                        The Serial Preferred Stock may be issued from time to

      fix or alter the rights, preferences, privileges and restrictions granted
      to or imposed upon any wholly unissued series of preferred shares, and the
      number of shares constituting any such series and a designation thereof,
      or any of them; and to increase or decrease the number of shares of any
      series subsequent to the issue of shares of that series, but not below the
      number of such series then outstanding. In case the number of shares of
      any series shall be so decreased, the shares constituting such decrease
      shall resume the status which they had prior to the adoption of the
      resolution originally fixing the number of shares of such series.

                  (b) Common Stock

                        (1) After the requirements with respect to preferential
      dividends upon all classes and series of stock entitled thereto shall have
      been paid or declared and set apart for payment and after the Corporation
      shall have complied with all requirements, if any, with respect to the
      setting aside of sums as a sinking fund or for a redemption account on any
      class of stock, then and not otherwise, the holders of Common Stock shall
      be entitled to receive, subject to the applicable provisions of the
      Corporations Code of the State of California, such dividends as may be
      declared from time to time by the Board of Directors.

      stock entitled thereto in the event of a voluntary or involuntary

      liquidation, dissolution, or winding up of the Corporation, as provided
      for in the Corporations Code of the State of California, the holders of
      the Common Stock shall be entitled to receive all the remaining assets of
      the Corporation.

                        (3) Each holder of Common Stock shall have one (1) vote
      in respect of each share of stock held by him, subject, however, to such
      special voting rights by class as are or may be granted to holders of
      Serial Preferred Stock.

      3. That the foregoing Amendment of Articles of Incorporation has been duly
approved by the required vote of shareholders in accordance with Section 902 of
the California Corporations Code. The total number of outstanding shares of the
Corporation is 1,216,573. The number of shares voting in favor of the Amendment
