                           The name of this corporation is:

                             Livingston Enterprises, Inc.


                                      ARTICLE II

    The purpose of this corporation is to engage in any lawful act or activity
    for which a corporation may be organized under the General Corporation Law
    of California other than the banking business, the trust company business or
    the practice of a profession permitted to be incorporated by the California
    Corporations Code.


                                      ARTICLE III


     (a) The corporation is authorized to issue two classes of shares designated
     "Preferred Stock" and "Common Stock," respectively. The number of shares of
     Preferred Stock authorized to be issued is five million (5,000,000) and the
     number of shares of Common Stock authorized to be issued is ten million 
     (10,000,000).

     (b) The Preferred Stock may be divided into such number of series as the 
     Board of Directors may determine. The Board of Directors is authorized to 
     determine and alter the rights, preferences, privileges, and restrictions 
     granted to and imposed upon any wholly unissued series of Preferred Stock,
     and to fix the number of shares of any series of Preferred Stock and the 
     designation of any such series of Preferred Stock. The Board of Directors,
     within the limits and restrictions stated in any resolution or resolutions
     of the Board of Directors originally fixing the number of shares
     constituting any series, may increase or decrease (but not below the number
     of shares of such series then outstanding) the number of shares of any 
     series subsequent to the issue of shares of that series.





                                      ARTICLE IV


     (a) The liability of directors of the corporation for monetary damages 
     shall be eliminated to the fullest extent permissible under California law.

     (b) The corporation is authorized to provide indemnification of agents (as
     defined in Section 317 of the California Corporations Code) through 
     bylaw provisions, agreements with agents, vote of shareholders or 
     disinterested directors, or otherwise, to the fullest extent permissible
     under California law.

     (c) Any amendment, repeal or modification of any provision of this 
     Article IV shall not adversely affect any right or protection of an agent
     of this corporation existing at the time of such amendment, repeal or 
     modification.

3.   The foregoing Amendment and Restatement of Article of Incorporation has 
     been duly approved by the Board of Directors of the corporation.

4.   The foregoing Amendment and Restatement of Articles of Incorporation has
     been duly approved by the required vote of shareholders in accordance with

     outstanding shares of the corporation is 675,000 (Common Stock). The number

     California that the matters set forth in this certificate are true and
     correct of our own knowledge.
