from December 19, 2001, until payment of said principal sum has been made or

of interest due on such January 15 or July 15 then this Note shall bear
interest from the next preceding January 15 or July 15 to which interest has
been paid or duly provided for or, if no interest has been paid or duly
provided for on the Notes, from December 19, 2001.  The interest so payable on

                               UNISYS CORPORATION
                           7 1/4% Senior Notes due 2005


     This Note is one of a duly authorized issue of Securities of the Company
designated as its 7 1/4% Senior Notes due 2005 (herein called the "Notes"),
issued under an Indenture dated as of May 1, 2001 (the "Indenture") between
the Company and HSBC Bank USA, as trustee (herein called the "Trustee", which
term includes any successor trustee under such Indenture), to which Indenture
and all indentures supplemental thereto reference is hereby made for a
statement of the respective rights, limitations of rights, obligations, duties
and immunities thereunder of the Company, the Trustee and the holders of the
Notes and of the terms upon which the Notes are, and are to be, authenticated
and delivered.

     If an Event of Default as defined in the Indenture shall have occurred
and be continuing, the principal of and accrued interest on the Notes of this
series may be declared and upon such declaration shall become due and payable
in the manner, with the effect and subject to the conditions provided in the
Indenture.

     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than 66-2/3% in the principal
amount of the Securities at the time outstanding of all series affected by
such supplemental indenture (voting as one class), evidenced as provided in
the Indenture, to execute supplemental indentures adding any provisions to or
changing in any manner or eliminating any of the provisions of the Indenture
or of any supplemental indenture or modifying in any manner the rights of the
holders of the Securities of each such series; provided, however, that no such
supplemental indenture shall (i) extend the final maturity of any Note, or
reduce the principal amount thereof, or reduce the rate or extend the time of
payment of interest thereon, or reduce any amount payable on redemption
thereof, or make the principal thereof or interest or premium, if any, thereon
payable in any coin or currency other than that provided in the Notes, or
impair or affect the right of the holder of any Note to institute suit for the
payment thereof, or (ii) reduce the aforesaid percentage of Securities of any
such series, the holders of which are required to consent to any such
supplemental indenture, without the consent of the holders of each Security so
affected.  It is also provided in the Indenture that, prior to any declaration
accelerating the maturity of the Notes, the holders of a majority in aggregate
principal amount of the Notes at the time outstanding may on behalf of the
holders of all of the Notes waive any past default or Event of Default under
the Indenture and its consequences, except a default in the payment of
interest or any premium on or the principal of any of the Notes.  Any such
consent or waiver by the holder of this Note (unless revoked as provided in
the Indenture) shall be conclusive and binding upon such holder and upon all
future holders and owners of this Note and any Notes which may be issued in
exchange or substitution therefor, irrespective of whether or not any notation
thereof is made upon this Note or such other Notes.

     No reference herein to the Indenture and no provision of this Note or of
the Indenture shall alter or impair the obligations of the Company, which are
absolute and unconditional, to pay the principal of and any premium and
interest on this Note at the place, at the respective times, at the rate and
in the coin or currency herein prescribed.

     Interest on the Notes shall be computed on the basis of a 360-day year of
twelve 30-day months.

     The provisions of the Indenture providing for defeasance of (i) the
entire indebtedness of this Note and (ii) certain restrictive covenants are
applicable to the Note.

     As set forth in, and subject to, the provisions of the Indenture, no
holder of any Note will have any right to institute any proceeding with
respect to the Indenture or for any remedy thereunder, unless (i) such holder
shall have previously given to the Trustee written notice of a continuing
Event of Default with respect to this series, (ii) the holders of not less
than 25% in principal amount of the Notes then outstanding shall have made
written request to the Trustee to institute such proceeding in respect of such
Event of Default in its own name as Trustee under the Indenture, (iii) such
holders shall have offered to the Trustee reasonable indemnity against the
costs, expenses and liabilities to be incurred in compliance with such
request, (iv) the Trustee for 60 days after its receipt of such notice,
request and offer of indemnity shall have failed to institute any such
proceeding and (v) the Trustee shall not have received from the holders of a
majority in principal amount of the Notes then outstanding direction
inconsistent with such request within such 60-day period; provided, however,
that such limitations do not apply to a suit instituted by the holder of a
Note for the enforcement of payment of the principal of, premium, if any, or
interest on the Note after the respective due date expressed herein.

     As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Note is registrable in the register for the
Notes, upon due presentation of this Note for registration of transfer at the
office or agency of the Company in any place where the principal of, and
premium, if any, on this Note are payable, duly endorsed by, or accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Trustee duly executed by, the holder of the Note or his attorney duly
authorized in writing, and thereupon one or more new Notes of this series of
like tenor or authorized denominations and for the same aggregate principal
amount will be issued to the designated transferee or transferees.

     The Notes of this series are issuable only in registered form without
coupons in denominations of $1,000 or any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations set forth
therein, Notes of this series are exchangeable for like aggregate principal
amount of Notes of like tenor of a different authorized denomination, as
requested by the holder of the Notes surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Note for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
person in whose name this Note is registered as the absolute owner of the Note
for all purposes, whether or not this Note be overdue, and none of the
Company, the Trustee or any such agent shall be affected by notice to the
contrary.
