of securities for Unisys Corporation (the "Company"), to:

(1)  execute for and on behalf of the undersigned Forms 3, 4 and 5 in accordance
with Section 16(a) of the Securities Exchange Act of 1934 and the rules
thereunder;

(2)  do and perform any and all acts for and on behalf of the undersigned which
may be necessary or desirable to complete the execution of any such Form 3, 4
or 5 and the timely filing of such form with the United States Securities and
Exchange Commission and any other authority; and

(3)  take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, the undersigned, it being
understood that the documents executed by such attorney-in-fact on behalf of
the undersigned pursuant to this Power of Attorney shall be in such form and
shall contain such terms and conditions as such attorney-in-fact may approve

The undersigned hereby grants to each such attorney-in-fact full power and
