                                   RISK FACTORS

     Please consider carefully the following factors, as well as the other 
information contained or referred to in this prospectus, before deciding to 
invest in the common stock.

WE FACE AGGRESSIVE COMPETITION AND RAPID TECHNOLOGICAL CHANGE IN THE INFORMATION
SERVICES AND TECHNOLOGY MARKETPLACE.

     Unisys operates in an industry characterized by aggressive competition, 
rapid technological change, evolving technology standards and short product life
cycles.  Our competitors include computer hardware manufacturers, software 
providers and information services companies, many of which have greater 
financial and other resources and are substantially less leveraged than Unisys. 
We compete primarily on the basis of product performance, service, technological
innovation, and price.  Our future operating results will depend on our ability 
to:

* design, develop, introduce, deliver or obtain new and innovative products and 
services on a timely and cost-effective basis;

* mitigate the effects of competitive pressures and volatility in the 
information services and technology market on revenues, pricing and margins; 

* effectively manage the shift of our business mix away from high margin 
proprietary products and maintenance to lower margin open systems and services 
offerings; and

* attract and retain highly skilled personnel.

WE HAVE EXPERIENCED PROBLEMS IN PROFITABLY PERFORMING SOME SYSTEMS INTEGRATION 
CONTRACTS.

     Some of our systems integration contracts are fixed-price contracts under 
which we assume the risk for the delivery of the contracted services and 
products at an agreed-upon fixed price.  At times we have experienced problems 
in performing some of these fixed-price contracts on a profitable basis and 
have provided periodically for adjustments to the cost to complete them.  
In the fourth quarter of 1995, we recorded a pretax charge for contract losses 
of $129.0 million, primarily relating to a few large multi-year, fixed-price 
systems integration contracts.  In the first quarter of 1997, we recorded 
charges of approximately $25 million for additional estimated contract costs 
identified during that quarter.  We could experience contract performance 
problems in the future, which could affect our results of operations.

WE ARE SUBJECT TO THE RISKS OF DOING BUSINESS INTERNATIONALLY. 

     Approximately 57% of our total revenue derives from international 
operations.  There is no material concentration of revenues in any particular 
country outside the United States.  Due to our foreign operations, we are 
exposed to the effects of foreign exchange rate fluctuations on the U.S. dollar.

     We use foreign exchange forward contracts and options, generally having 
maturities of less than nine months, to reduce this exposure.  We use these 
contracts and options for the sole purpose of hedging transactional exposures.  
We do not hold or issue financial instruments for speculative trading purposes. 
In addition to fluctuations in foreign currency exchange rates, many other 
factors beyond our control could affect our international business.  These 
include instability of foreign economies, U.S. and foreign government laws and 
policies affecting trade and investment, and governmental changes.  

THERE COULD BE UNANTICIPATED NEGATIVE CONSEQUENCES AND COSTS ASSOCIATED WITH THE
YEAR 2000 READINESS OF OUR PRODUCT OFFERINGS AND INTERNAL SYSTEMS.

     Many computer systems and embedded technology may experience problems 
handling dates beyond the year 1999 and therefore may need to be modified before
the year 2000 in order to remain functional.  We have been taking actions to 
ensure both the readiness of our product offerings to customers 





<PAGE> 4

and the readiness of our internal systems for handling dates beginning in the 
year 2000.  Although we do not believe that we will incur material costs or 
experience material disruptions in our business associated with the year 2000, 
we could experience serious unanticipated negative consequences and/or material 
costs.  These could include increased customer satisfaction costs related to 
year 2000, potential litigation, changing customer spending patterns, and 
undetected errors or defects associated with year 2000 date functions in our 
current product offerings.

WE ARE HIGHLY LEVERAGED AND HAVE SUBSTANTIAL CASH REQUIREMENTS.

* Debt was approximately $1.2 billion at December 31, 1998 and approximately 
$1.7 billion at December 31, 1997.

* Total interest expense was $171.7 million for 1998 and $233.2 million for 
1997.

* Our debt-to-capital ratio was 43% at December 31, 1998 and 58% at December 31,
1997.

* At December 31, 1998 we had approximately 28.4 million shares of convertible 
preferred stock outstanding. The annual dividend on the preferred stock is $3.75
per share.  Dividends paid in 1998 amounted to $106.5 million.  During the first
quarter of 1999, approximately 4.8 million shares of preferred stock were 
converted into common stock, and approximately 3.4 million shares were redeemed 
for $168.3 million in cash.  After giving effect to these actions, there were 
approximately 20.2 million shares of preferred stock outstanding, with an 
aggregate annual dividend of approximately $75.8 million.

* We expect our total cash requirements associated with the restructuring 
actions discussed below to be approximately $84 million in 1999 and $47 million 
thereafter.

* During 1998, cash provided by operations was $650.0 million, cash used for 
investing activities was $275.0 million, and cash used for financing activities 
(primarily early repayments of debt) was $570.7 million.  In 1997, cash provided
by operations was $383.5 million, cash used for investing activities was $291.6 
million, and cash used for financing activities (primarily redemption of 
preferred stock) was $274.1 million.

     At December 31, 1998, our cash balance was $604.3 million.  Nevertheless, 
we may require continued access to financing sources to meet our cash 
requirements.  This access may not always be available to us.

WE HAVE INCURRED SPECIAL CHARGES AND EXPERIENCED NET LOSSES IN THE PAST.

     Unisys operates in an industry characterized by ongoing dramatic changes, 
including, in our case, a shift from higher margin mainframe products to lower 
margin products and services.  In order to improve our operating results, we 
have moved aggressively to realign our operations to reflect the rapidly 
changing market for information processing products and services.

* In the fourth quarter of 1997, we took a one-time charge of $1.1 billion 
against net income.  After this charge, we reported a net loss of $853.6 million
for the full year.  The charge included:

   - $127.0 million principally related to our decision to discontinue the 
     manufacturing and assembly of personal computers and low-end servers and 
     to dispose of a small, non-strategic technology product;

   - the writeoff of $883.6 million in goodwill principally related to the 1986 
     merger of Burroughs Corporation and Sperry Corporation; and

   - $42.0 million related to the conversion, in December 1997, of $271.2 
     million of our 8 1/4% convertible subordinated notes due 2006.




<PAGE> 5

* In the fourth quarter of 1996, we took charges of $84 million relating to the 
refocusing and discontinuance of certain products and programs.  After the 
charges and an extraordinary item, we reported net income of $49.7 million for 
the full year.

* In 1995, we reported a net loss of $624.6 million.  The loss included a fourth
quarter pretax restructuring charge of $717.6 million, primarily relating to our
internal realignment into three operating units and covering work force 
reductions, product and program discontinuances and consolidation of office 
facilities and manufacturing capacity. 

* We recorded special pretax charges of $186.2 million in 1994, $1.2 billion in 
1991, and $181.0 million in 1990.  Principally due to these special charges, we 
had net losses of $1.4 billion in 1991 and $436.7 million in 1990.

Although Unisys recorded no special charges in 1998, we could incur special 
charges and/or experience losses in the future.

WE DO NOT PAY DIVIDENDS ON THE COMMON STOCK. 

     Unisys has not declared or paid any cash dividends on its common  stock 
since 1990 and does not anticipate declaring or paying dividends on it in the 
foreseeable future.  


                                  THE COMPANY

     Unisys is a worldwide information services and technology company that 
provides systems and solutions to help customers apply information technology to
solve their business problems.

     Unisys was incorporated in February 1984 and is the successor by merger to 
Burroughs Corporation, incorporated in 1905.  In November 1986, Sperry 
Corporation was merged into the company, and the company's name was changed to 
Unisys Corporation.


                                 USE OF PROCEEDS

     We will be offering and issuing the common stock from time to time in 
connection with our acquisition of other companies.  We will not receive any 
cash proceeds from these offerings.

                          DESCRIPTION OF COMMON STOCK

GENERAL

     The authorized capital stock of Unisys consists of 720,000,000 shares of 
common stock and 40,000,000 shares of preferred stock.  As of February 28, 
1999, there were approximately 263.4 million shares of common stock and 
approximately 24.7 million shares of Series A Cumulative Convertible Preferred 
Stock (the "Series A Preferred Stock") outstanding.  The Board of Directors 
has also authorized the issuance of 1.5 million shares of Junior Participating
Preferred Stock (the "Junior Preferred Stock"), none of which is currently 
outstanding.

     Subject to the rights of the holders of shares of preferred stock, holders 
of shares of common stock (1) are entitled to receive dividends when and as 
declared by the Board of Directors from funds legally available for that 
purpose; (2) except as otherwise may be required by law, have the exclusive 
right to vote, and (3) are entitled, upon any liquidation, dissolution or 
winding up of Unisys, to a pro rata distribution of the assets and funds 
available for distribution to stockholders. Each share of common stock is 
entitled to one vote on all matters on which stockholders generally are entitled
to vote. Holders of shares of common stock do not have preemptive rights to 
subscribe for additional shares of common stock or securities convertible into 
shares of common stock.




<PAGE> 7

     The common stock is listed on the New York Stock Exchange under the symbol 
UIS.  Harris Trust Company of New York is the transfer agent for the common 
stock. 

DIVIDEND LIMITATIONS

     Unisys has not declared or paid any cash dividends on the common stock 
since 1990 and does not anticipate declaring or paying dividends on the common 
stock in the foreseeable future.  

PREFERRED SHARE PURCHASE RIGHTS AND JUNIOR PARTICIPATING PREFERRED STOCK

     Unisys has distributed to its stockholders one Preferred Share Purchase 
Right (the "Rights") for each outstanding share of common stock pursuant to a 
Rights Agreement dated as of March 7, 1986.  Each Right entitles its holder, 
until the earlier of March 17, 2001 or the redemption of the Rights, to buy one 
three-hundredth of a share of the Junior Preferred Stock at an exercise price of
$75.  The Rights are represented by the certificates for shares of common stock 
and will not be exercisable, or transferable apart from the shares of common 
stock, until the earlier of the tenth day after the announcement that a person 
or group has acquired beneficial ownership of 20% or more of the shares of 
common stock (a "20% holder") or the tenth day after a person commences, or 
announces an intention to commence, an offer, the consummation of which would 
result in a person beneficially owning 30% or more of the shares of common stock
as of such date (the earlier of these dates being called the "Distribution 
Date").  The Rights could then begin trading separately from the shares of 
common stock. 

     If Unisys is acquired in a merger or other business combination 
transaction, each Right will entitle its holder to purchase, at the exercise 
price of the Right, that number of shares of common stock of the surviving 
company which, at the time of the transaction, would have a market value of two 
times the exercise price of the Right. Alternatively, if a 20% holder were to 
acquire Unisys by means of a reverse merger in which Unisys and its stock 
survive, or were to engage in certain "self-dealing" transactions, each Right 
not owned by the 20% holder would become exercisable for the number of shares of
common stock which, at that time, would have a market value of two times the 
exercise price of the Right. 

     The Rights are redeemable at $.01 2/3 per Right at any time prior to the 
time that a person or group becomes a 20% holder.  The Rights will expire on 
March 17, 2001 (the "Final Expiration Date"), unless  Unisys extends the Final 
Expiration Date or redeems the Rights earlier.  At no time will the Rights have 
any voting rights. 

     The above is only a summary.  You should refer to the Rights Agreement that
is filed as an exhibit to the Registration Statement for a complete description 
of the Rights. 

     The shares of Junior Preferred Stock purchasable upon exercise of the 
Rights will be nonredeemable.  Each share of Junior Preferred Stock will have a 
minimum preferential quarterly dividend of $15 per share, but will be entitled 
to a dividend of 300 times the aggregate dividend declared per share of common 
stock.  In the event of liquidation, the holders of the shares of Junior 
Preferred Stock will receive a preferred liquidation payment of $100 per share, 
but will be entitled to receive an aggregate liquidation payment per share equal
to 300 times the payment made per share of common stock.  Each share of the 
Junior Preferred Stock will have 300 votes, voting together with the shares of 
common stock.  In the event of any merger, consolidation or other transaction in
which shares of common stock are exchanged, each share of the Junior Preferred 
Stock will be entitled to receive 300 times the amount received per share of 
common stock.  The Junior Preferred Stock has customary antidilution provisions 
to protect the dividend, liquidation and voting rights described above. 

     The purchase price payable, and the number of shares of Junior Preferred 
Stock or other securities or property issuable, upon exercise of the Rights are 
subject to adjustment from time to time to prevent dilution in the event of 
certain dividends on, reclassifications of, or distributions to the holders of, 
Junior Preferred Stock.  The percentage of a share of Junior Preferred Stock for
which a Right is exercisable and the number of Rights outstanding are also 
subject to adjustment in the event of dividends on the shares of common stock 
payable in shares of common stock or subdivisions, combinations or 
consolidations of the 




<PAGE> 8

shares of common stock, occurring, in any case, before the Rights become 
exercisable or transferable apart from the shares of common stock. 

     One Right is presently associated with each issued and outstanding share of
common stock.  Unisys will issue one Right with each share of common stock 
issued prior to the Final Expiration Date unless, prior to the issuance, the 
Rights are redeemed or become exercisable and transferable apart from the shares
of common stock. 

     The Rights have anti-takeover effects.  The Rights may cause substantial 
dilution to a person or group that attempts to acquire Unisys on terms that the 
Board of Directors determines are not in the best interests of Unisys 
stockholders.  The Rights should not interfere with any merger or other business
combination approved by the Board of Directors since the Rights may be redeemed 
at $.01 2/3 per Right prior to the time that a person or group has acquired 
beneficial ownership of 20% or more of the shares of common stock. 

ANTI-TAKEOVER PROVISIONS

     Delaware Law.  Unisys is a Delaware corporation and subject to Section 203 
of the Delaware General Corporation Law. Generally, Section 203 prohibits a 
publicly held Delaware corporation from engaging in a "business combination" 
with an "interested stockholder" for a period of three years after the time of 
the transaction in which the person became an interested stockholder.  The 
provision does not apply if (1) prior to such time, either the business 
combination or such transaction is approved by the board of directors of the 
corporation; (2) upon consummation of the transaction which results in the 
stockholder becoming an interested stockholder, the interested stockholder owns 
at least 85% of the outstanding voting stock or (3) on or after such time the 
business combination is approved by the board and by the affirmative vote of at 
least 66 2/3% of the outstanding voting stock that is not owned by the 
interested stockholder.  A "business combination" includes mergers, asset sales 
and other transactions resulting in a financial benefit to the interested 
stockholder.  An "interested stockholder" is a person who, together with 
affiliates and associates, owns (or within three years, did own) 15% or more of 
the corporation's outstanding voting stock. 

     Corporate Documents.  Our Certificate of Incorporation and By-Laws also 
contain anti-takeover provisions that are intended to enhance the likelihood of 
continuity and stability in the composition of the Board of Directors and that 
may have the effect of delaying, deferring or preventing a future takeover or 
change in control unless the Board approves it.  These provisions may also make 
it more difficult to remove the current Board of Directors. 

* Classified board -- The Certificate of Incorporation and By-Laws provide that 
the Board of Directors shall have no fewer than 10 and no more than 20 members, 
with the exact number to be fixed by the Board of Directors.  The Board of 
Directors is divided into three classes of directors, as nearly equal in number 
as possible.  One class of directors is elected each year for a term of three 
years.  

* Removal of directors; vacancies -- Directors may be removed from office only 
for cause and only by the affirmative vote of at least 80% of the outstanding 
voting stock.  Vacancies in the Board of Directors and newly created 
directorships are filled for the unexpired term only by the vote of a majority 
of the remaining directors in office.

* Special meetings of stockholders -- Under the Certificate of Incorporation and
By-Laws, stockholders may not call a special meeting of stockholders.  Only the 
Board of Directors, by resolution adopted by a majority of the entire Board, may
call a special meeting of stockholders.  

* Action by written consent -- The Delaware General Corporation Law provides 
that, unless specifically prohibited by the certificate of incorporation, any 
action required or permitted to be taken by stockholders of a corporation may be
taken without a meeting if a written consent setting forth the action to be 
taken is signed by the holders of outstanding shares of capital stock having the
requisite number of votes that would be necessary to authorize or take such 




<PAGE> 9

action at a meeting of stockholders.  Our Certificate of Incorporation requires 
that stockholder action be taken at a meeting of stockholders and prohibits 
stockholder action by written consent. 

* Business combinations -- The Certificate of Incorporation provides that 
mergers, consolidations, sales or other transfers of assets of, issuances or 
reclassifications of securities of, or adoptions of plans of liquidation by 
Unisys (individually, a "Business Combination") must be approved by 80% or more 
of the voting stock when the action involves a person (an "Interested 
Stockholder") who beneficially owns more than 20% of the then outstanding shares
of voting stock, unless minimum price, form of consideration and procedural 
requirements (the "Fair Price Provisions") are satisfied or unless a majority of
the directors not affiliated with the Interested Stockholder approve the 
Business Combination.  

     The affirmative vote of 80% or more of the then outstanding shares of 
voting stock is required to amend, alter or repeal the provisions of the 
Certificate of Incorporation and By-Laws discussed above.

     The purpose of the provisions of the Certificate of Incorporation and By-
Laws relating to (1) a classified Board of Directors; (2) the removal of 
directors and the filling of vacancies; (3) the prohibition of stockholder 
action by written consent and (4) supermajority voting requirements for the 
repeal of these provisions is to help assure the continuity and stability of our
business strategies and policies and to discourage certain types of transactions
that involve an actual or threatened change of control of Unisys.  They are 
designed to make it more difficult and time-consuming to change majority control
of the Board of Directors and thus to reduce the vulnerability of Unisys to an 
unsolicited takeover proposal that does not contemplate the acquisition of at 
least 80% of the voting stock or to an unsolicited proposal for the 
restructuring or sale of all or part of the company. 

     These charter and by-law provisions may make more difficult or discourage a
proxy contest, or the assumption of control, by a holder of a substantial block 
of shares of common stock, or the removal of the incumbent Board of Directors, 
and could thus increase the likelihood that incumbent directors will retain 
their positions.  In addition, since the Fair Price Provisions discussed above 
provide that Business Combinations involving Unisys and an Interested 
Stockholder may not be consummated without the approval of a majority of 
unaffiliated directors (unless the transaction meets specified criteria or is 
approved by supermajority vote), these provisions could give incumbent 
management the power to prevent certain takeovers.  The Fair Price Provisions 
may also discourage attempts to effect a "two-step" acquisition in which a third
party purchases a controlling interest in cash and acquires the balance of the 
voting stock for less desirable consideration.  Under the classified board and 
related provisions, the third party would not immediately obtain the ability to 
control the Board of Directors through its first-step acquisition and, under the
Fair Price Provisions, having made the first-step acquisition, the third party 
could not acquire the balance of the voting stock for a lower price without a 
supermajority vote or the approval of a majority of the unaffiliated directors. 

     These provisions of the Certificate of Incorporation and By-Laws help 
ensure that the Board of Directors, if confronted with an unsolicited proposal 
from a third party which has acquired a block of shares of Common stock, will 
have sufficient time to review the proposal and to consider appropriate 
alternatives for Unisys stockholders. 

     These provisions are also intended to encourage persons seeking to acquire 
control of Unisys to initiate such an acquisition through arm's-length 
negotiations with the Board of Directors, who would then be in a position to 
negotiate a transaction that would treat all stockholders in substantially the 
same manner.  The provisions may have the effect of discouraging a third party 
from making an unsolicited tender offer or otherwise attempting to obtain 
control of Unisys, even though such an attempt might be beneficial to the 
company and its stockholders. In addition, since the provisions are designed to 
discourage accumulations of large blocks of shares of common stock by purchasers
whose objective is to have those shares repurchased by the company at a premium,
the provisions could tend to reduce the temporary fluctuations in the market 
price of common stock caused by these accumulations. Accordingly, Unisys 
stockholders could be deprived of the opportunity to sell their shares at a 
temporarily higher market price. 




<PAGE> 10

     The Rights could also have the effect of delaying, deferring or preventing 
a takeover or change in control of Unisys.  See "Preferred Share Purchase Rights
and Junior Participating Preferred Stock". 

CERTAIN PROVISIONS OF OUTSTANDING PREFERRED STOCK

     The Series A Preferred Stock accrues quarterly cumulative dividends at the 
annual rate of $3.75 per share and is entitled to receive $50 per share, plus 
accrued and unpaid dividends, upon liquidation.  Each share of Series A 
Preferred Stock is currently convertible, at the option of its holder,  into 
1.67 shares of common stock.  The Series A Preferred Stock prohibits the payment
of cash dividends or other distributions on, and the purchase, redemption or 
other acquisition of, any shares of junior stock, including the common stock, 
until all accrued and unpaid dividends on the Series A Preferred Stock have been
paid.

                                     PART II

                        INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law (the "DGCL") provides 
for, among other things:

a.  permissive indemnification for expenses, judgments, fines and amounts paid 
in settlement actually and reasonably incurred by designated persons, including 
directors and officers of a corporation, in the event such persons are parties 
to litigation other than stockholder derivative actions if certain conditions 
are met;

b.  permissive indemnification for expenses actually and reasonably incurred by 
designated persons, including directors and officers of a corporation, in the 
event such persons are parties to stockholder derivative actions if certain 
conditions are met;

c.  mandatory indemnification for expenses actually and reasonably incurred by 
designated persons, including directors and officers of a corporation, in the 
event such persons are successful on the merits or otherwise in litigation 
covered by a. and b. above; and

d.  that the indemnification provided for by Section 145 shall not be deemed 
exclusive of any other rights which may be provided under any by-law, agreement,
stockholder or disinterested director vote, or otherwise.

     The Unisys Certificate of Incorporation provides that a director shall not 
be personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director except for liability (i) for any breach 
of the director's duty of loyalty to the Company or its stockholders, (ii) for 
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) for paying a dividend or approving a stock 
repurchase in violation of Section 174 of the DGCL or (iv) for any transaction 
from which the director derived an improper personal benefit.

     The Certificate of Incorporation also provides that each person who was or 
is made a party to, or is involved in, any action, suit or proceeding by reason 
of the fact that he or she is or was a director or officer of the Company (or 
was serving at the request of the Company as a director, officer, employee or 
agent for another entity) shall be indemnified and held harmless by the Company,
to the fullest extent authorized by the DGCL, as in effect (or, to the extent 
indemnification is broadened, as it may be amended) against all expense, 
liability or loss reasonably incurred by such person in connection therewith.  
The Certificate of Incorporation further provides that such rights to 
indemnification are contract rights and shall include the right to be paid by 
the Company the expenses incurred in defending the proceedings specified above, 
in advance of their final disposition, provided that, if the DGCL so requires, 
such payment shall only be made upon delivery to the Company by the indemnified 
party of an undertaking to repay all amounts so advanced if it shall ultimately 
be determined that the person receiving such payment is not entitled to be 

<PAGE> II-2

indemnified.  Persons so indemnified may bring suit against the Company to 
recover unpaid amounts claimed thereunder, and if such suit is successful, the 
expense of bringing such suit shall be reimbursed by the Company.  The 
Certificate of Incorporation provides that the right to indemnification and to 
the advance payment of expenses shall not be exclusive of any other right which 
any person may have or acquire under any statute, provision of the Company's 
Certificate of Incorporation or By-Laws, or otherwise. By resolution effective 
September 16, 1986, the Board of Directors extended the right to indemnification
provided directors and officers by the Certificate of Incorporation to employees
of the Company. The Certificate of Incorporation also provides that the Company 
may maintain insurance, at its expense, to protect itself and any of its 
directors, officers, employees or agents against any expense, liability or loss,
whether or not the Company would have the power to indemnify such person against
such expense, liability or loss under the DGCL. 

     On April 28, 1988, at the Unisys 1988 Annual Meeting of Stockholders, the 
stockholders authorized the Company to enter into indemnification agreements 
("Indemnification Agreements") with its directors, and such Indemnification 
Agreements have been executed with each of the directors of the Company. The 
Indemnification Agreements provide that the Company shall, except in certain 
situations specified below, indemnify a director against any expense, liability 
or loss (including attorneys' fees, judgments, fines, ERISA excise taxes or 
penalties and amounts paid in settlement) incurred by the director in connection
with any actual or threatened action, suit or proceeding (including derivative 
suits) in which the director may be involved as a party or otherwise, by reason 
of the fact that the director is or was serving in one or more capacities as a 
director or officer of the Company or, at the request of the Company, as a 
director, officer, employee or agent of another corporation, partnership, joint 
venture, trust, employee benefit plan or other entity or enterprise. 

     The Indemnification Agreements require indemnification except to the extent
(i) payment for any liability is made under an insurance policy provided by the 
Company, (ii) indemnification is provided by the Company under the Certificate 
of Incorporation or By-Laws, the DGCL or otherwise than pursuant to the 
Indemnification Agreement, (iii) the liability is based upon or attributable to 
the director gaining any personal pecuniary profit to which such director is not
legally entitled or is determined to result from the director's knowingly 
fraudulent, dishonest or willful misconduct, (iv) the liability arises out of 
the violation of certain provisions of the Securities Exchange Act of 1934 or 
(v) indemnification has been determined not to be permitted by applicable law. 

     The Indemnification Agreements further provide that, in the event of a 
Potential Change in Control (as defined therein), the Company shall cause to be 
maintained any then existing policies of directors' and officers' liability 
insurance for a period of six years from the date of a Change in Control (as 
defined therein) with coverage at least comparable to and in the same amounts as
that provided by such policies in effect immediately prior to such Potential 
Change in Control.  In the event of a Potential Change in Control, the 
Indemnification Agreements also provide for the establishment by the Company of 
a trust (the "Trust"), for the benefit of each director, upon the written 
request by the director.  The Trust shall be funded by the Company in amounts 
sufficient to satisfy any and all liabilities reasonably anticipated at the time
of such request, as agreed upon by the director and the Company. 



<PAGE> II-3

     The Indemnification Agreements also provide that no legal actions may be 
brought by or on behalf of the Company, or any affiliate of the Company, against
a director after the expiration of two years from the date of accrual of such 
cause of action, and that any claim or cause of action of the Company or its 
affiliate shall be extinguished and deemed released unless asserted by the 
timely filing of a legal action within such two year period. 

     The directors and officers of Unisys are insured against certain civil 
liabilities, including liabilities under federal securities laws, which might be
incurred by them in such capacity.

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

(1)  To file, during any period in which offers or sales are being made, a post-
effective amendment to this Registration Statement: 

(i)  To include any prospectus required by Section 10(a)(3) of the Securities 
Act of 1933 (the "Securities Act"); 

(ii)  To reflect in the prospectus any facts or events arising after the 
effective date of the Registration Statement (or the most recent post-effective 
amendment thereof) which, individually or in the aggregate, represent a 
fundamental change in the information set forth in the Registration Statement.  
Notwithstanding the foregoing, any increase or decrease in volume of securities 
offered (if the total dollar value of securities offered would not exceed that 
which was registered) and any deviation from the low or high end of the 
estimated maximum offering range may be reflected in the form of prospectus 
filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the 
changes in volume and price represent no more than 20 percent change in the 
maximum aggregate offering price set forth in the "Calculation of Registration 
Fee" table in the effective registration statement; 

(iii)  To include any material information with respect to the plan of 
distribution not previously disclosed in the Registration Statement or any 
material change to such information in the Registration Statement; 

(2)  That, for the purpose of determining any liability under the Securities 
Act, each such post-effective amendment shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof; 

(3)  To remove from registration by means of a post-effective amendment any of 
the securities being registered which remain unsold at the termination of the 
offering;

(4)  That, for purposes of determining any liability under the Securities Act, 
each filing of the registrant's annual report pursuant to Section 13(a) or 
Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by 
reference in the Registration Statement shall be deemed to be a new Registration
Statement relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.



<PAGE> II-5

(5)  That prior to any public reoffering of the securities registered hereunder 
through use of a prospectus which is a part of this Registration Statement, by 
any person or party who is deemed to be an underwriter within the meaning of 
Rule 145(c), the issuer undertakes that such reoffering prospectus will contain 
the information called for by the applicable registration form with respect to 
reofferings by persons who may be deemed underwriters, in addition to the 
information called for by the other items of the applicable form.

(6)  That every prospectus: (I) that is filed pursuant to paragraph (5) above, 
or (ii) that purports to meet the requirements of Section 10(a)(3) of the 
Securities Act and is used in connection with an offering of securities subject 
to Rule 415, will be filed as a part of an amendment to the Registration 
Statement and will not be used until such amendment is effective, and that, for 
purposes of determining any liability under the Act, each such post-effective 
amendment shall be deemed to be a new Registration Statement relating to the 
securities offered therein, and the offering of such securities at that time 
shall be deemed to be the initial bona fide offering thereof."

    Insofar as indemnification for liabilities arising under the Securities Act 
may be permitted to directors, officers and controlling persons of the 
registrant pursuant to the provisions described in Item 20 above, or otherwise, 
the registrant has been advised that in the opinion of the Securities and 
Exchange Commission such indemnification is against public policy as expressed 
in the Securities Act and is, therefore, unenforceable. In the event a claim for
indemnification against such liabilities (other than the payment by the

RE:     Registration Statement on Form S-4

Gentlemen:

I am the Senior Vice President, General Counsel and Secretary of Unisys 
Corporation, a Delaware corporation (the "Company").  I have represented the 
Company, with assistance from attorneys under my supervision in the Company's 
Office of the General Counsel (the "Unisys Attorneys"), in connection with the 
preparation of a Registration Statement on Form S-4 (the "Registration 
Statement") registering 6,000,000 shares (the "Shares") of the Company's common 
stock, par value $.01 per share, and associated preferred share purchase 
rights, under the Securities Act of 1933, as amended (the "Act").  The Company 
will issue the Shares from time to time in connection with its acquisition of 
other companies.

In connection with this opinion, I or the Unisys Attorneys have reviewed (a) the
Registration Statement, (b) the Company's Certificate of Incorporation and (c) 
the Company's By-laws.  In addition, I or the Unisys Attorneys have examined 
such corporate records of the Company, such certificates of public officials, 
officers and representatives of the Company and such other certificates and 
instruments and have made such
 investigations of law as I or they have deemed 
appropriate for purposes of giving the opinions hereinafter expressed.

With respect to the opinion set forth below, I have assumed (a) that the 
issuance and delivery of the Shares by the Company will be consistent with the 
Delaware General Corporation Law and the Company's Certificate of Incorporation 
and By-laws as in effect at the time of such issuance and delivery and (b) that 
the consideration to be received by the Company upon the issuance of any Shares 
will be at least equal to the par value of such Shares. 

Based upon the foregoing, I am of the opinion that the Shares, when issued as 
described in the Registration Statement, will be validly issued, fully paid and 
non-assessable.

I hereby consent to the filing of this opinion as Exhibit 5 to the Registration 
Statement and to the reference to me under the caption "Legal Matters" in the 
prospectus contained therein.  In giving such consent, I do not thereby admit 
that I am an expert with respect to any part of the Registration Statement, 
including this exhibit, within the meaning of the term "expert" as used in the 
Act or the rules and regulations issued thereunder.




This opinion is limited to the General Corporation Law of the State of 
Delaware.

Very truly yours,


Harold S. Barron
