Unisys Offers Total of $550 Million of Senior Notes; Company Announces
Tender Offer for 8 1/8% Senior Notes Due 2006

Unisys Corporation (NYSE:UIS) said that it has offered a total of $550 million
of senior notes, more than previously announced due to strong market demand. The
notes were offered in two tranches: $400 million of 8% senior notes due 2012,
which were priced at par, and $150 million of 8.5% senior notes due 2015, which
were priced at par. Banc of America Securities LLC and Citigroup Global Markets
Inc. are joint bookrunning managers of the offerings, which are scheduled to be
completed next week.

Also as previously announced, the company is commencing a tender offer and
consent solicitation for all $400 million of its 8 1/8% senior notes due 2006.
The tender offer will be financed by the above-mentioned senior notes. In
conjunction with the tender offer, the company is soliciting holders of the 8
1/8% notes to consent to certain proposed amendments to the indenture governing
the notes.

Unisys said, assuming all $400 million of the 8 1/8% notes are tendered, it will
take an estimated pre-tax charge in the third quarter of approximately $13
million for the premium paid for the notes and unamortized debt expense.

The tender for the 8 1/8% notes will expire at 5:00 p.m., New York City time, on
October 7, 2005, unless extended (the 'Expiration Date'). The consent
solicitation will expire at 5:00 p.m., New York City time, on September 15,
2005, unless extended (the 'Consent Date'). Holders tendering their notes will
be required to consent to certain proposed amendments to the indenture governing
the notes, which will eliminate substantially all of the restrictive covenants
and certain events of default. Holders may not tender their notes without
delivering consents or deliver consents without tendering their notes. Holders
may withdraw their tenders and revoke their consents at any time prior to 5:00
p.m., New York City time, on the Consent Date, but not thereafter.

Holders who validly tender their notes and provide consents to the proposed
amendments on or prior to the Consent Date will receive a consent payment of $20
per $1,000 principal amount of notes as part of their total consideration. In
such case, the total consideration, including the consent payment, to be paid
for each validly tendered note and delivered consent will be a price based on a
fixed spread of 50 basis points over the yield of the 2.5% U.S. Treasury Note
due May 31, 2006. The pricing formula assumes that the notes would otherwise be
paid in full at maturity on June 1, 2006. The yield of the reference U.S.
Treasury Note used in the fixed spread formula will be set at 2:00 p.m., New
York City time, on the business day following the Consent Date. Unisys expects
to pay the total consideration on the second business day following the Consent
Date for notes validly tendered on or prior to the Consent Date and accepted for
purchase.

Holders who validly tender their notes and provide consents after the Consent
Date and on or prior to the Expiration Date are not entitled to the $20 consent
payment, and will receive as payment for their notes the total consideration
minus the consent payment. Unisys expects to make payment promptly after the
Expiration Date for notes validly tendered and accepted for purchase after the
Consent Date and prior to the Expiration Date. Holders who validly tender their
notes will also be paid accrued and unpaid interest up to, but not including,
the applicable payment date for their notes. Holders may withdraw their tenders
and revoke their consents at any time prior to 5:00 p.m., New York City time, on
the Consent Date but not thereafter.

The terms and conditions of the tender offer and consent solicitation, including
the obligation to accept the notes tendered and pay the offer consideration and
consent payments, are set forth in the Offer to Purchase and Consent
Solicitation Statement, dated September 9, 2005. Unisys may amend, extend or,
subject to certain conditions, terminate the tender offer and consent
solicitation.

Unisys has retained Citigroup Global Markets Inc. and Banc of America Securities
LLC to act as the exclusive dealer managers and solicitation agents in
connection with the tender offer and consent solicitation for the 8 1/8% notes.

Reform Act of 1995. Forward-looking statements include, but are not limited to,
any projections of earnings, revenues, contract values or other financial items;
any statements of the company's plans, strategies or objectives; and any
statements of belief or expectation. All forward-looking statements rely on
assumptions and are subject to various risks and uncertainties that could cause
actual results to differ materially from expectations. The closing of the
offerings of the new senior notes is subject to customary closing conditions,
and the consummation of the tender offer is conditioned, among other things, on
the issuance of the new senior notes. The company's ability to repurchase the 8
1/8% notes is also dependent upon their holders' willingness to tender them to
the company. The estimated pre-tax charge associated with the tender offer is
subject to change based upon final determination of the tender offer price. A
discussion of other factors that could affect Unisys future results is contained
in its periodic filings with the Securities and Exchange Commission. Unisys
assumes no obligation to update any forward-looking statements.
