                        AMENDMENT TO EMPLOYMENT AGREEMENT


            This Amendment to Employment Agreement is entered into as of the 1st
of September, 2000, by and between A. Lorne Weil ("Executive") and Autotote
Corporation, a Delaware corporation (the "Company").

            WHEREAS, the Company and Executive have entered into an Employment
Agreement dated as of November 1, 1997, as amended by the letter agreement dated
September 10, 1998 (the "Existing Agreement"); and

            WHEREAS, the Company and Executive wish to amend certain provisions
of the Existing Agreement concerning the term of Executive's employment;
Executive's base salary; and Executive's rights upon termination with respect to
any supplemental executive retirement plan or similar plan;

            NOW, THEREFORE, in consideration of the premises and the mutual
benefits to be derived herefrom and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties hereto
agree that the Existing Agreement is hereby amended, effective as of September
1, 2000, as follows:

                  1. TERM: Section 2 of the Existing Agreement is hereby amended
and restated to provide in its entirety as follows:

            The term of employment of Executive under this Agreement (the
            "Term") shall be the period commencing on the Effective Date and
            ending on October 31, 2004, together with any additional period or
            periods for which such term may be extended from time to time in
            accordance with this Section 2, subject to earlier termination in
            accordance with Section 6 or 7. The Term shall be extended

                                       1

            automatically, without further action by either party, by one
            additional year beyond the then-scheduled end of the Term, on
            October 31, 2004 (extending the Term to October 31, 2005) and on
            each succeeding October 31 thereafter, unless either party, prior to
            the April 30 preceding the date upon which such extension would
            become effective, shall have served upon the other party written
            notice in accordance with the provisions of Section 12(d) electing
            not to so extend the Term, in which case the term of Executive's
            employment shall terminate at the then-scheduled end of the Term,
            subject to earlier termination in accordance with Section 6 or 7.


                  2. BASE SALARY: Section 4(a) the Existing Agreement is hereby
amended and restated to provide in its entirety as follows:

            The Company will pay to Executive during the Term a base salary at
            the initial annual rate of $475,000, payable in cash in
            substantially equal monthly installments during each year, or
            portion thereof, of the Term commencing at the beginning of the
            Term, and otherwise in accordance with the Company's usual payroll
            practices with respect to senior executives (except to the extent
            deferred under Section 5(d)). Executive's annual base salary shall
            be increased to $750,000 effective September 1, 2000, and shall be
            increased annually on each succeeding September 1 thereafter by a
            percentage of Executive's annual base salary then in effect equal to
            the percentage increase, if any, during the preceding twelve months
            in the Consumer Price Index for the Greater New York area; provided,
            however, that if the independent consultants that the Company
            retains to review the Company's compensation structure conclude that
            Executive's base salary is insufficient, Executive's base salary
            shall be increased in accordance with the recommendations of such
            consultants. In no event shall Executive's base salary be reduced.
