            CERTIFICATE OF AMENDMENT OF ARTICLES OF INCORPORATION OF

                            A CALIFORNIA CORPORATION

     M. Mark Michalko and Lawrence E. Logue certify that:

     1. They are the President and Secretary of International Lottery & 
Totalizator Systems, Inc., a California corporation.

     2. The Articles of Incorporation of said corporation shall be amended by
revising Article Four to read as follows:

          "FOUR: This corporation is authorized to issue two classes of shares
     designated respectively "Common Stock" and "Preferred Stock," and referred
     to either as Common Stock or Common shares and Preferred Stock or
     Preferred shares, respectively. The authorized number of shares of Common
     Stock is 50,000,000. Upon the amendment of this Article, each outstanding
     share of Common Stock is converted into 0.333 shares.

          The authorized number of shares of Preferred Stock is 20,000,000. The
     Preferred Stock may be issued from time to time in one or more series. The
     Board of Directors is authorized to fix the number of shares of any series
     of Preferred Stock and to determine the designation of any such series. The
     Board of Directors is also authorized to determine or alter the rights,
     privileges, designations, preferences and restrictions granted to or
     imposed upon any wholly unissued series of Preferred Stock and, 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, to increase or decrease (but not below the number of shares of such
     series then outstanding) the number of shares of any such series subsequent
     to the issue of shares of that series." 

     3. The foregoing amendment of the Articles of Incorporation has been duly 
approved by the Board of Directors.

     4. The foregoing amendment of the 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 the outstanding shares is 
18,027,548. The number of shares voting in favor of the amendment equaled or 
exceeded the vote required. The percentage vote required was more that 50%.

     We further declare under penalty of perjury under the laws of the State of 
California that the matters set forth in this certificate are true and correct 
of our own knowledge.
