Re:  Amendment to Consulting Agreement

Dear Larry:

    This letter serves as an amendment to the consulting agreement between
Ceridian Corporation and you dated May 1, 2000. The agreement is amended to
reflect December 1, 2000 rather than December 31, 2000 as the conclusion of the
consulting engagement. All other terms and conditions of the agreement remain
the same, including the second payment of $125,000 which is due and payable to
you on November 1, 2000.

    Please give me a call if you have questions (952/853-3301).

Sincerely,
/s/ Shirley J. Hughes
