                            Report of Independent Auditors

Unisys Corporation
Employee Benefits Administrative Committee

We have audited the accompanying statements of assets available for benefits of
the Unisys Savings Plan (the "Plan") as of December 31, 2001 and 2000, and the
related statements of changes in assets available for benefits for the years
then ended. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with auditing standards generally
accepted in the United States.  Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provided
a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the assets available for benefits of the Plan at
December 31, 2001 and 2000, and the changes in its assets available for
benefits for the years then ended, in conformity with accounting principles
generally accepted in the United States.

Our audits were performed for the purpose of forming an opinion on the
financial statements taken as a whole. The accompanying supplemental schedule
of assets (held at end of year) as of December 31, 2001, is presented for
purposes of additional analysis and is not a required part of the financial
statements but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This supplemental schedule is the
responsibility of the Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in our audits of the financial
statements and, in our opinion, is fairly stated in all material respects in
relation to the financial statements taken as a whole.

                        Notes to Financial Statements
                              December 31, 2001


1. PLAN DESCRIPTION

The Unisys Savings Plan (the Plan) is a defined contribution plan that covers
nonbargaining employees paid from a United States payroll of Unisys
Corporation (the Company) and bargaining unit employees whose collective
bargaining agreement provides for participation in the Plan. The Employee
Benefits Administrative Committee is the Plan administrator. The Plan is
subject to the provisions of the Employee Retirement Income Security Act of
1974 (ERISA).

Participants should refer to the Plan document, summary plan description and
their respective bargaining unit agreement, if applicable, for complete
information.

CONTRIBUTIONS

Non-highly compensated employees may contribute up to 20% of their pretax
compensation, as defined in the Plan.  Highly compensated employees could
contribute up to 12% and 18% of their pretax compensation, in 2000 and 2001,
respectively, as defined in the Plan. The Plan allows the Company to make
discretionary matching contributions, as determined by the Company's Board of
Directors. The matching contribution is made in Company common stock and was
50% of the first 4% of pretax compensation contributed by the participant
during 2001 and 2000. The Plan also allows for rollover contributions from
other qualified defined contribution plans.

INVESTMENT OPTIONS

Participants may elect to have their current contributions and existing
account balances invested in any one or more of the investment options offered
and managed by Fidelity Management & Research Company and Fidelity Management
Trust Company (Fidelity). Information regarding the investment options is
provided to each participant through electronic media and prepared materials
provided by the Company and in each investment fund's prospectus made
available by Fidelity.

1. PLAN DESCRIPTION (continued)

PARTICIPANT ACCOUNTS

Participant accounts are credited with requested pre-tax, after-tax, rollover,
participant contributions, Company contributions and an allocation of
investment income (losses), and they are charged with an allocation of
administrative expenses. Allocations are based on participant earnings or
account balances, as determined. The benefit to which a participant is
entitled is equal to the vested portion of their account.

VESTING AND FORFEITURES

Plan participants are immediately vested in their account balances at all times.

DISTRIBUTIONS/WITHDRAWALS

On termination of service, a participant may receive a lump-sum amount equal
to his or her account, or upon death, disability or retirement, elect to
receive payments in the form of an annuity or annual installments over the
participant's actuarially determined lifetime. Plan participants also may
receive in-service withdrawals in certain circumstances as defined in the
Plan. Loans are also available to Plan participants in accordance with Plan
rules and procedures.

PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right
under the Plan to discontinue its matching contributions and/or to terminate
the Plan at any time subject to the provisions of ERISA.

2. SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from those
estimates.

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

INVESTMENT VALUATION AND INCOME RECOGNITION

The Plan's investments are stated at fair value, except for the Unisys
Interest Income Fund which includes investments in guaranteed investment
contracts issued principally by insurance companies and financial institutions
which are valued at contract value as estimated by the insurance companies.
Contract value represents contributions and reinvested income, less any
withdrawals plus accrued interest, because these investments have fully benefit
responsive features. All participant initiated transactions with the fund are
permitted at contract value with no conditions, limits or restrictions.
However, withdrawals influenced by Company-initiated events, such as in
connection with the sale of a business, may result in a distribution at other
than contract value. No reserves have been provided or are considered
necessary against contract values for credit risk of contract issuers or
otherwise. Contract value of these investment contracts approximates their
fair value. Interest accrued on the contract balances, during 2001 and 2000,
at rates ranging from 2.12% to 6.35% and from 5.02% to 8.71%, respectively.
Interest rates are set at the time the contract is negotiated and, depending
on the terms of the contract, are fixed through the maturity date or are
re-set quarterly, semi-annually or annually. The average yield on the
contracts was 6.51% and 6.24% for 2001 and 2000, respectively.

As of December 31, 2001 and 2000, because of the large number of investment
contracts with numerous counterparties, the Plan had no significant
concentrations of credit risk.

Shares of registered investment companies are valued at quoted market prices,
which represent net asset values of shares held by the Plan at year-end.
Shares of Unisys common stock are valued at the closing market price on the
last day of the Plan year. Participant loans are valued at the outstanding
principal balance, which approximates fair value.

Purchases and sales of securities are recorded on a trade-date basis. Interest
income is reported on the accrual basis. Dividends are recorded on the ex-
dividend date. Realized gains and losses from securities sold are reported on
an average cost basis.

Investments in Frozen Investment Contracts represent the cash balance from
payments made to the Plan from the Conservation Estate of the Executive Life
Insurance Company (ELIC) and from state guaranty associations in settlement of
claims made by the Plan as a result of the insolvency of ELIC. The remaining
cash balance at December 31, 2001 represents amounts that will be allocated to
Plan participants or applied to pay administrative expense of the Plan.

RECLASSIFICATIONS

Certain prior-year amounts have been reclassified to conform with the 2001
presentation.

3. INVESTMENTS

The Plan's investments at December 31, 2001 and 2000 were held in trusts with
Fidelity Management Trust Company, First Union National Bank, and Oriental Bank
& Trust, each of which was established for the investment of the Plan's assets.

During 2001 and 2000, the Plan's investments (including investments purchased,
sold, as well as held during the year) (depreciated) appreciated in fair value
as follows (in thousands):


                                              2001                 2000

  Commingled Pool Fund                           (3,528)            (3,108)

                                        ======================================

Investments that represent 5% or more of fair value of the Plan's assets are
as follows:
