owned directly by the Fidelity Funds, which power resides with the 
Funds' Boards of Trustees.  Fidelity carries out the voting of the 
shares under written guidelines established by the Funds' Boards of 
Trustees.

Massachusetts 02109, a wholly-owned subsidiary of FMR Corp. and a bank 
as defined in Section 3(a)(6) of the Securities Exchange Act of 1934,

provides investment advisory services to individuals. It does not have

SCHEDULE 13G - TO BE INCLUDED IN STATEMENTS
FILED PURSUANT TO RULE 13d-1(b) or 13d-2(b)

Pursuant to instructions in Item 7 of Schedule 13G, this Exhibit 
has been prepared  to identify Fidelity International Limited, Pembroke 
Hall, 42 Crow Lane, Hamilton, Bermuda, a Bermudan joint stock company 
incorporated for an unlimited duration by private act of the Bermuda 
Legislature (FIL) and an investment adviser to various investment 
companies (the "International Funds") and certain institutional 
investors, as a beneficial owner of the 33,100 shares or 0.010% of the 
common stock outstanding of Unisys Corporation.

Prior to June 30, 1980, FIL was a majority-owned subsidiary of 
Fidelity Management & Research Company (Fidelity), a wholly-owned 
subsidiary of FMR Corp.  On that date, the shares of FIL held by 
Fidelity were distributed, as a dividend,  to the shareholders of FMR 
Corp.  FIL currently operates as an entity independent of FMR Corp. and 
Fidelity.  The International Funds and FIL's other clients, with the 
exception of Fidelity and an affiliated company of Fidelity, are non-
U.S. entities.

A partnership controlled by Edward C. Johnson 3d and members of 
his family owns shares of FIL voting stock with the right to cast 
approximately 39.89% of the total votes which may be cast by all 
holders of FIL voting stock.  Mr. Johnson 3d is Chairman of FMR Corp. 
and FIL.  FMR Corp. and FIL are separate and independent corporate 
entities, and their Boards of Directors are generally composed of 
different individuals.  Other than when one serves as a sub adviser to 
the other, their investment decisions are made independently, and their 
clients are generally different organizations.

FMR Corp. and FIL are of the view that they are not acting as a 
"group" for purposes of Section 13(d) under the Securities Exchange Act 
of 1934 (the "1934" Act) and that they are not otherwise required to 
attribute to each other the "beneficial ownership" of securities 
"beneficially owned" by the other corporation within the meaning of 
Rule 13d-3 promulgated under the 1934 Act.  Therefore, they are of the 
view that the shares held by the other corporation need not be 
aggregated for purposes of Section 13(d). However, FMR Corp. is making 
this filing on a voluntary basis as if all of the shares are 
beneficially owned by FMR Corp. and FIL on a joint basis.

FIL may continue to have the International Funds or other 
accounts purchase shares subject to a number of factors, including, 
among others, the availability of shares for sale at what FIL considers 
to be reasonable prices and other investment opportunities that may be 
available to the International Funds.

FIL intends to review continuously the equity position of the 
International Funds and other accounts in the Company.  Depending upon 
its future evaluations of the business and prospects of the Company and 
upon other developments, including, but not limited to, general 
economic and business conditions and money market and stock market 
conditions, FIL may determine to cease making additional purchases of 
shares or to increase or decrease the equity interest in the Company by 
acquiring additional shares, or by disposing of all or a portion of the 
shares.

FIL does not have a present plan or proposal which relates to or 
would result in (i) an extraordinary corporate transaction, such as a 
merger, reorganization, liquidation, or sale or transfer of a material 
amount of assets involving the Company or any of its subsidiaries, (ii) 
any change in the Company's present Board of Directors or management, 
(iii) any material changes in the Company's present capitalization or 
dividend policy or any other material change in the Company's business 
or corporate structure, (iv) any change in the Company's charter or by-
laws, or (v) the Company's common stock becoming eligible for 
termination of its registration pursuant to Section 12(g)(4) of the 
1934 Act.

FIL  has sole power to vote and the sole power to dispose of  
33,100  shares.
