   We are a worldwide information services and technology company that provides
services, systems and solutions to help customers apply information technology
to seize the opportunities and overcome the challenges of the Internet economy.
We have two business segments--services and technology.

   In the services segment, we integrate and deliver the solutions, services
and network infrastructure required by business and government to transform
their organizations for the Internet economy. We offer a portfolio of solutions
targeted at key vertical industries: financial services, communications,
transportation, commercial, and public sector. Offerings in the services
segment include vertical industry and custom solutions, systems integration,
outsourcing, network services and multi-vendor information systems management
and support.

   In the technology segment, we develop servers and related products which
operate in high-volume, mission-critical environments. Major offerings include
enterprise-class servers such as the ClearPath enterprise server, which
integrates proprietary and "open" platforms; Windows 2000 servers with
enterprise-class attributes, such as the ES7000 server line based on the
Cellular MultiProcessing architecture; system middleware to power high-end
servers; storage products; payment systems; and specialized technologies.

   We market our products and services primarily through a direct sales force.
In certain foreign countries, we market primarily through distributors. We
manufacture a significant portion of our product lines. Some products,
including certain commodity and small servers, peripheral products, and
software products, are manufactured for us to our design or specifications by
other business equipment manufacturers or software suppliers.

   No single customer accounts for more than 10% of our revenue. Sales of
commercial products to various agencies of the U.S. government represented 10%
of total consolidated revenue in 2000.

   Our principal executive offices are located at Unisys Way, Blue Bell,
Pennsylvania 19424. Our telephone number is (215) 986-4011.

                                  RISK FACTORS

   In addition to the other information contained and incorporated in this
prospectus supplement and the accompanying prospectus, you should consider
carefully the following factors before deciding to purchase the notes. Our
business is also affected by changes in general economic and business
conditions, acts of war, terrorism and natural disasters.

We face aggressive competition and rapid technological change in the
information services and technology marketplace.

   We operate 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, some of which may have greater
financial and other resources than we have. We compete primarily on the basis
of service, product performance, 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;

  . our ability to succeed in the high-end information technology services
    segment;

  . our ability to effectively manage the shift in our technology business
    into higher growth, lower margin, standards-based server products;

  . our ability to mitigate the effects of competitive pressures and
    volatility in the information services and technology market on revenues,
    pricing and margins;

  . our ability to attract and retain highly skilled personnel; and

  . market demand for and acceptance of our services and product offerings.

Our future results will depend on our ability to profitably perform our
contracts.

   A number of our contracts are long-term contracts for network services,
outsourcing, help desk and similar services, for which volumes are not
guaranteed. Our future results will depend upon our ability to meet performance
levels over the terms of these 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. Our
future results will depend on our ability to profitably perform these services
contracts and bid and obtain new contracts.

   We frequently enter into contracts with governmental entities. Risks and
uncertainties associated with these government contracts include the
availability of appropriated funds and contractual provisions that allow
governmental entities to terminate agreements in their discretion before the
end of their terms.

Our future results will depend in part on the performance and capabilities of
third parties.

   We have commercial relationships with suppliers, channel partners and other
parties that have complementary products, services, or skills. Our future
results will depend in part on:

  . the performance and capabilities of these third parties;

  . the ability of external suppliers to deliver components at reasonable
    prices and in a timely manner; and

  . the financial condition of, and our relationship with, distributors and
    other indirect channel partners.

                                      S-2


We are subject to the risks of doing business internationally.

   We derive approximately 57% of our total revenue from international
operations. We do not have a 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.

   We use foreign exchange forward contracts and options to reduce this
exposure. We use these contracts and options for the sole purpose of hedging
transactional exposures and 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.

Holders of notes will be taxed on original issue discount.

   The notes will be issued at a discount from their principal amount.
Consequently, holders of the notes generally will be required to include
amounts in gross income for United States federal income tax purposes in
advance of receipt of the cash payments to which this income is attributable.
See "Certain United States Federal Income Tax Consequences" for a more detailed
discussion of the United States federal income tax consequences to holders of
the purchase, ownership and disposition of the notes.

                                USE OF PROCEEDS

   We estimate that the net proceeds from the issuance and sale of the notes,
after reduction for the discount to purchasers of the notes, and after
deducting the underwriters' discounts and commissions, and approximately
$150,000 in expenses relating to the offering, will be approximately $146.6
million. We plan to use these proceeds for general corporate purposes.

                              RECENT DEVELOPMENTS

   In our quarterly report on Form 10-Q for the third quarter of 2001, we
disclosed our plans to take a charge in the fourth quarter to cover a workforce
reduction and other actions. We currently expect this pre-tax charge to be
approximately $225 million to $250 million, primarily for a worldwide workforce
reduction of about 3,000 positions plus a U.S. early retirement incentive
accepted by 750 employees.

                              DESCRIPTION OF NOTES

General

   The following description of the notes we are offering supplements, and to
the extent inconsistent therewith supersedes, the description of the general
terms and provisions of the Debt Securities set forth in the accompanying
prospectus. We refer you to that description.

   We will issue the notes under an indenture dated as of May 1, 2001 between
us and HSBC Bank USA, as trustee. The trustee has normal banking relationships
with us and participates as a lender in our revolving credit facility. An
affiliate of the trustee is also an underwriter for this offering.

   We do not currently intend to list the notes on any securities exchange or
to seek approval for quotation through any automated quotation system. We
cannot assure you that an active public market for the notes will develop. The
absence of an active public trading market could have an adverse effect on the
liquidity and value of the notes.

Principal, Maturity and Interest

   The aggregate principal amount of the notes is $150.0 million. Each note
will mature on January 15, 2005 and will bear interest at the rate per annum
shown on the cover page of this prospectus supplement. Interest on the notes
will accrue from the date of original issuance, or from the most recent
interest payment date to which interest has been paid or provided for. We will
pay interest on the notes semi-annually on January 15 and July 15 of each year,
commencing July 15, 2002, to holders of record at the close of business on the
immediately preceding January 1 and July 1, respectively.

   Interest on the notes will be paid by check mailed to the persons in whose
names the notes are registered at the close of business on the applicable
record date or, at our option, by wire transfer to accounts maintained by such
persons with a bank located in the United States. The principal of the notes
will be paid upon surrender of the notes at the corporate trust office of the
trustee. For so long as the notes are represented by global notes, we will make
payments of interest by wire transfer to The Depository Trust Company ("DTC")
or its nominee, as the case may be, which will distribute payments to
beneficial holders in accordance with its customary procedures. See "--Book-
Entry, Delivery and Form."

   The notes may not be redeemed prior to maturity and are not entitled to any
sinking fund. The provisions of the indenture described in the accompanying
prospectus under "Description of the Debt Securities--Defeasance" will apply to
the notes.

Ranking

   The notes will be senior unsecured obligations, ranking equally with all of
our existing and future senior indebtedness and senior to any future
subordinated indebtedness.

Book-Entry, Delivery and Form

   The notes will be issued in the form of one or more global notes deposited
with, or on behalf of, DTC and registered in the name of Cede & Co., as nominee
of DTC.

   DTC is a limited-purpose trust company that was created to hold securities
for its participating organizations (collectively, the "Participants") and to
facilitate the clearance and settlement of transactions in securities between
Participants through electronic book-entry changes in accounts of Participants.
The Participants include securities brokers and dealers, banks and trust
companies, clearing corporations, and certain other organizations. Access to
DTC's system is also available to other entities such as banks, brokers,
dealers and trust companies (collectively, the "Indirect Participants") that
clear through or maintain a custodial

                                      S-5


relationship with a Participant, either directly or indirectly. Persons who are
not Participants may beneficially own securities held by or on behalf of DTC
only through the Participants or the Indirect Participants.

   We expect that under procedures established by DTC: (1) upon deposit of the
global note, DTC will credit the accounts of Participants with portions of the
principal amount of the global note; and (2) ownership of the notes evidenced
by the global note will be shown on, and the transfer of ownership thereof will
be effected only through, records maintained by DTC (with respect to the
interests of Participants), the Participants and the Indirect Participants. The
laws of some states require that certain persons take physical delivery in
definitive form of securities that they own. Consequently, the ability to
transfer notes evidenced by the global note will be limited to that extent.

   The holder of the global note will be considered the sole holder under the
indenture of any notes evidenced by the global note. Beneficial owners of notes
evidenced by the global note will not be considered the owners or holders
thereof under the indenture for any purpose, including with respect to the
giving of any directions, instructions or approvals to the trustee thereunder.
Neither we nor the trustee will have any responsibility or liability for any
aspect of the records of DTC or for maintaining, supervising, or reviewing any
records of DTC relating to the notes.

   Payments in respect of the principal of, premium, if any, and interest on
any notes registered in the name of the holder of the global note on the
applicable record date will be payable by the trustee to or at the direction of
the holder of the global note in its capacity as the registered holder under
the indenture. Under the terms of the indenture, we and the trustee may treat
the persons in whose names notes, including the global note, are registered as
the owners thereof for the purpose of receiving payments. Consequently, neither
we nor the trustee have or will have any responsibility or liability for the
payment of these amounts to beneficial owners of notes. We believe, however,
that it is currently the policy of DTC to immediately credit the accounts of
the relevant Participants and Indirect Participants with payments, in amounts
proportional to their respective holdings of beneficial interests in the
relevant security as shown on the records of DTC. Payments by Participants and
Indirect Participants to the beneficial owners of notes will be governed by
standing instructions and customary practice and will be the responsibility of
the Participants or Indirect Participants.

   Certificated Securities. A person having a beneficial interest in the global
note may exchange the beneficial interest for notes in the form of registered
definitive certificates only under limited circumstances described in the
accompanying prospectus. Upon any such exchange, the trustee is required to
register the certificated securities in the name of, and cause the same to be
delivered to, that person or persons (or the nominee of any thereof). In
addition, if: (1) we notify the trustee in writing that DTC is no longer
willing or able to act as a depositary and we are unable to locate a qualified
successor within 90 days, or if at any time DTC ceases to be a "clearing
agency" registered under the Exchange Act, or (2) we, at our option, notify the
trustee in writing that we elect to cause the issuance of notes in the form of
certificated securities under the indenture, then upon surrender by the holder
of the global note of its global note, notes in such form will be issued to
each person that the holder of the global note and DTC identify as being the
beneficial owner of the related notes. Neither we nor the trustee will be
liable for any delay by the holder of the global note or DTC in identifying the
beneficial owners of notes, and we and the trustee may conclusively rely on,
and will be protected in relying on, instructions from the holder of the global
note or DTC for all purposes.

Same-Day Settlement and Payment

   Settlement for the notes will be made by the underwriters in immediately
available funds. We will make all payments of principal and interest in
immediately available funds.

   Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearing-house or next-day funds. In contrast, the notes
will trade in the Same-Day Funds Settlement System maintained by DTC until
maturity, and secondary market trading activity in the notes will therefore be
required by DTC to settle in immediately available funds. We cannot assure you
as to the effect, if any, of settlement in immediately available funds on
trading activity in the notes.

                         CERTAIN UNITED STATES FEDERAL
                            INCOME TAX CONSEQUENCES

   The following summary describes the material United States federal income
tax consequences of the ownership of notes at their issue price as of the date
hereof. Except where noted, it deals only with notes held as capital assets by
purchasers purchasing the notes pursuant to this offering and does not deal
with special situations. In addition, it does not represent a detailed
description of the U.S. federal income tax consequences applicable to you if
you are subject to special treatment under the tax laws, including if you are
one of the following:

  .  a dealer in securities or currencies;

  .  a financial institution;

  .  a tax-exempt entity;

  .  an insurance company;

  .  a person holding notes as a part of a hedging, integrated, conversion,
     or constructive sale transaction or a straddle;

  .  a regulated investment company;

  .  a real estate investment trust;

  .  a trader in securities that elects to use a mark-to-market method of
     accounting for its securities holdings;

  .  a person liable for alternative minimum tax; or

  .  a holder of notes whose "functional currency" is not the U.S. dollar.

   If a partnership holds our notes, the tax treatment of a partner will
generally depend upon the status of the partner and the activities of the
partnership. If you are a partner of a partnership holding our notes, you
should consult your tax advisors.

   The discussion below is based upon the provisions of the Internal Revenue
Code of 1986, as amended (the "Code"), and regulations, rulings and judicial
decisions thereunder as of the date hereof. Such authorities may be repealed,
revoked or modified so as to result in United States federal income tax
consequences different from those discussed below. Persons considering the
purchase, ownership or disposition of notes should consult their own tax
advisors concerning the United States federal income tax consequences in light
of their particular situations as well as any consequences arising under the
laws of any other taxing jurisdiction.

   As used herein, a "U.S. Holder" of a note means a holder that is:

  .  a citizen or resident of the United States;

  .  a corporation or partnership created or organized in or under the laws
     of the United States or any political subdivision thereof;

  .  an estate the income of which is subject to United States federal income
     taxation regardless of its source; or

  .  a trust if it (1) is subject to the primary supervision of a court
     within the United States and one or more United States persons have the
     authority to control all substantial decisions of the trust or (2) has a
     valid election in effect under applicable U.S. Treasury regulations to
     be treated as a United States person.

   A "Non-U.S. Holder" is a holder that is not a U.S. Holder.

                                      S-7


Consequences to U.S. Holders

   The following is a summary of the material U.S. federal income tax
consequences that will apply to you if you are a U.S. Holder of notes.

 Payments of Interest

   Except as set forth below, stated interest on a note will generally be
taxable to you as ordinary income at the time it is paid or accrued in
accordance with your method of accounting for tax purposes.

 Original Issue Discount

   The notes will be issued with original issue discount ("OID") in an amount
equal to the difference between their stated redemption price at maturity (the
sum of all payments to be made on the note other than stated interest) and
their "issue price." You should be aware that you generally must include OID in
gross income in advance of the receipt of cash attributable to that OID.
However, you generally will not be required to include separately in income the
cash payments that are attributable to OID.

   The "issue price" of each note will be the first price at which a
substantial amount of the notes is sold (other than to an underwriter,
placement agent or wholesaler).

   The amount of OID you must include in income is the sum of the "daily
portions" of OID with respect to the note for each day during the taxable year
or portion of the taxable year in which you held that note ("accrued OID"). The
daily portion is determined by allocating to each day in any "accrual period" a
pro rata portion of the OID allocable to that accrual period. The "accrual
period" for a note may be of any length and may vary in length over the term of
the note, provided that each accrual period is no longer than one year and each
scheduled payment of principal or interest occurs on the first day or the final
day of an accrual period. The amount of OID allocable to any accrual period is
an amount equal to the excess, if any, of:

  .  the note's adjusted issue price at the beginning of such accrual period
     times its yield to maturity determined on the basis of compounding at
     the close of each accrual period and properly adjusted for the length of
     the accrual period, over

  .  the aggregate of all stated interest allocable to the accrual period.

   OID allocable to a final accrual period is the difference between the amount
payable at maturity, other than a payment of stated interest, and the adjusted
issue price at the beginning of the final accrual period. Special rules will
apply for calculating OID for an initial short accrual period. The "adjusted
issue price" of a note at the beginning of any accrual period is equal to its
issue price increased by the accrued OID for each prior accrual period and
reduced by any payments made on the note (other than stated interest) on or
before the first day of the accrual period. Under these rules, you will have to
include in income increasingly greater amounts of OID in successive accrual
periods. We are required to provide information returns stating the amount of
OID accrued on notes held of record by persons other than corporations and
other exempt holders.

   You may elect to treat all interest on any note as OID and calculate the
amount includible in gross income under the constant yield method described
above. For purposes of this election, interest includes stated interest,
acquisition discount, OID, market discount, de minimis market discount and
unstated interest, as adjusted by any amortizable bond premium or acquisition
premium. You must make this election for the taxable year in which you acquired
the note, and you may not revoke the election without the consent of the
Internal Revenue Service. You should consult with your own tax advisors about
this election.


 Sale, Exchange and Retirement of Notes

   Upon the sale, exchange, retirement or other disposition of a note, you will
recognize gain or loss equal to the difference between the amount realized upon
the sale, exchange, retirement or other disposition (less an

                                      S-8


amount equal to any accrued interest, which will be treated as a payment of
interest) and your adjusted tax basis of the note. In general, your tax basis
in a note will be equal to your cost of the note increased by accrued OID and
reduced by any cash payments on the notes other than stated interest. Such gain
or loss will be capital gain or loss. Capital gains of individuals derived in
respect of capital assets held for more than one year are eligible for reduced
rates of taxation. The deductibility of capital losses is subject to
limitations.

 Information Reporting and Backup Withholding

   In general, information reporting requirements will apply to certain
payments of principal and interest paid on the notes and to the proceeds of
sale of a note made to you, unless you are an exempt recipient, like a
corporation. A backup withholding tax will apply to those payments if you fail
to provide a taxpayer identification number, a certification of exempt status,
or fail to report in full dividend or interest income.

Consequences to Non-U.S. Holders

   The following is a summary of the material U.S. federal income tax
consequences that will apply to you if you are a Non-U.S. Holder of notes. A
"Non-U.S. Holder" is any beneficial holder of a note that is not a U.S. Holder,
as defined above. This summary does not represent a detailed description of the
U.S. federal income tax consequences to you in light of your particular
circumstances. In addition, it does not deal with Non-U.S. Holders that are
subject to special treatment under the U.S. federal income tax laws including
if you are acontrolled foreign corporation, passive foreign investment company,
foreign personal holding company, a corporation that accumulates earnings to
avoid U.S. federal income tax, or, in certain circumstances, a United States
expatriate.

 U.S. Federal Withholding Tax

   The 30% U.S. federal withholding tax will not apply to any payment of
principal or interest (which for purposes of this discussion includes OID) on a
note provided that:

  . you do not actually (or constructively) own 10% or more of the total
    combined voting power of all classes of our voting stock within the
    meaning of the Code and applicable U.S. Treasury Regulations;

  . you are not a controlled foreign corporation that is related to us
    through stock ownership;

  . you are not a bank whose receipt of interest on the notes is described in
    section 881(c)(3)(A) of the Code; and

  . either (1) you provide your name and address on an IRS Form W-8BEN, and
    certify, under penalty of perjury, that you are not a United States
    person or (2) you hold your notes through certain foreign intermediaries
    and you satisfy the certification requirements of applicable U.S.
    Treasury regulations.

Special certification rules apply to certain non-U.S. holders that are entities
rather than individuals.

   If you cannot satisfy the requirements described above, payments of interest
(including OID) made to you will be subject to the 30% U.S. federal withholding
tax, unless you provide us with a properly executed (1) IRS Form W-8BEN (or
other applicable form) claiming an exemption from or reduction in withholding
under the benefit of an applicable tax treaty or (2) W-8ECI (or successor form)
stating that interest paid on a note is not subject to withholding tax because
it is effectively connected with your conduct of a trade or business in the
United States.

   The 30% U.S. federal withholding tax will not apply to any gain that you
realize on the sale, exchange, retirement or other disposition of a note.

 U.S. Federal Estate Tax

   Your estate will not be subject to U.S. federal estate tax on notes
beneficially owned by you at the time of your death, provided that (1) you do
not own 10% or more of the total combined voting power of all classes of our
voting stock (within the meaning of the Code and the U.S. Treasury Regulations)
and (2) interest on that

                                      S-9


note would not have been, if received at the time of your death, effectively
connected with the conduct by you of a trade or business in the United States.

 U.S. Federal Income Tax

   If you are engaged in a trade or business in the United States and interest
(including OID) on the notes is effectively connected with the conduct of that
trade or business (although exempt from the 30% withholding tax), you will be
subject to U.S. federal income tax on that interest and OID on a net income
basis in generally the same manner as if you were a U.S. person as defined
under the Code. In addition, if you are a foreign corporation, you may be
subject to a branch profits tax equal to 30% (or lower applicable treaty rate)
of your effectively connected earnings and profits for the taxable year,
subject to adjustments.

   Any gain realized on the disposition of a note generally will not be subject
to U.S. federal income tax unless:

  . the gain is effectively connected with the conduct of a trade or business
    in the United States by you, or

  . you are an individual who is present in the United States for 183 days or
    more in the taxable year of that disposition, and certain other
    conditions are met.

 Information Reporting and Backup Withholding

   In general, you will not be subject to backup withholding and information
reporting with respect to payments that we make to you provided that we do not
have actual knowledge or reason to know that you are a U.S. person and we have
received from you the statement described above under "U.S. Federal Withholding
Tax."

   In addition, you will not be subject to backup withholding or information
reporting with respect to the proceeds of the sale of a note within the United
States or conducted through certain U.S.-related financial intermediaries, if
the payor receives the statement described above and does not have actual
knowledge or reason to know that you are a U.S. person, as defined under the
Code, or you otherwise establish an exemption.

   Any amounts withheld under the backup withholding rules will be allowed as a
refund or a credit against your U.S. federal income tax liability provided the
required information is furnished to the IRS.

                                  UNDERWRITING

   Subject to the terms and conditions set forth in the Underwriting Agreement
Basic Provisions dated July, 1996 and the related Terms Agreement dated
December 14, 2001 (collectively, the "Underwriting Agreement") among us and the
underwriters, each of the underwriters named below (the "Underwriters") has
severally agreed to purchase from us the principal amount of notes set forth
opposite its name below.



                                                                    Principal

                                                                   ------------
  Total........................................................... $150,000,000
                                                                   ============


   The Underwriting Agreement provides that the obligations of the several
Underwriters thereunder are subject to approval of certain legal matters by
counsel and to various other conditions. The Underwriters are obligated to
purchase and accept delivery of all of the notes if they purchase any of the
notes.

   The Underwriters propose to offer the notes directly to the public at the
public offering price set forth on the cover page of this prospectus supplement
and to certain securities dealers at such price less a concession not in excess
of 0.50% per note. The Underwriters may allow, and such dealers may re-allow,
concessions not in excess of 0.25% per note on sales to other dealers. After
the offering of the notes, the public offering price, concessions and other
selling terms may be changed by the Underwriters. The notes are offered subject
to receipt and acceptance by the Underwriters and to certain other conditions,
including the right to reject orders in whole or in part.

   We have agreed to indemnify the Underwriters against certain liabilities
under the Securities Act of 1933 or to contribute to payments that the
Underwriters may be required to make in respect thereof.

   In order to facilitate the offering, certain persons participating in the
offering may engage in transactions that stabilize, maintain or otherwise
affect the price of the notes during and after the offering. Specifically, the
Underwriters may over-allot or otherwise create a short position in the notes
for their own account by selling more notes than have been sold to them by us.
The Underwriters may elect to cover any such short position by purchasing notes
in the open market. In addition, the Underwriters may stabilize or maintain the
price of the notes by bidding for or purchasing notes in the open market and
may impose penalty bids, under which selling concessions allowed to syndicate
members or other broker-dealers participating in the offering are reclaimed if
notes previously distributed in the offering are repurchased in connection with
stabilization transactions or otherwise. The effect of these transactions may
be to stabilize or maintain the market price of the notes at a level above that
which might otherwise prevail in the open market. The imposition of a penalty
bid may also affect the price of the notes to the extent that it discourages
resales thereof.

   From time to time, some of the Underwriters or their affiliates have
provided, and may continue to provide in the future, investment banking,
general financing and banking services to us and our affiliates, for which they
have received, and expect to receive, customary compensation. Each of the
Underwriters, or their affiliates, is a lender in our revolving credit
facility. Affiliates of Salomon Smith Barney Inc. and Banc of America
Securities LLC were also co-arrangers of the revolving credit facility. An
affiliate of HSBC Securities (USA) Inc. is the trustee for the notes.

                                  RISK FACTORS

     This Prospectus contains or incorporates by reference certain forward-
looking statements, as defined in the Private Securities Litigation Reform Act
of 1995.  All forward-looking statements rely on assumptions and are subject to
risks, uncertainties and other factors that could cause the Company's actual
results to differ materially from expectations.  These include, but are not
limited to, the risk factors set forth below.  Prospective investors should
consider carefully, in addition to the other information contained and
incorporated by reference herein, the following factors before deciding to
purchase the Securities offered hereby.

Competitive Marketplace

     The Company operates in an industry characterized by aggressive
competition, rapid technological change, evolving technology standards and short
product life cycles.  The Company's competitors include computer hardware
manufacturers, software providers and information services companies, many of
which have greater financial and other resources than the Company and are
substantially less leveraged.  The Company competes primarily on the basis of
product performance, service, technological innovation and price.  Future
operating results will depend on the Company's ability to design, develop,
introduce, deliver or obtain new and innovative products and services on a
timely and cost-effective basis; on its ability to mitigate the effects of
competitive pressures and volatility in the information technology and services
market on revenues, pricing and margins; and on its ability to effectively
manage the shift of its business mix away from traditional high margin product
and services offerings.

High Leverage and Cash Requirements

     At December 31, 1997 and December 31, 1996, the Company had approximately
$1.7 billion and $2.3 billion principal amount of debt, respectively.  Total
interest expense for 1997 and 1996 was $233.2 million and $249.7 million,
respectively.  The Company's debt-to-capital ratio was 58% at December 31, 1997
and 59% at December 31, 1996.

     The Company has outstanding $1.4 billion of Series A convertible preferred
stock.  Dividends paid on the Series A preferred stock in 1997 amounted to
$106.3 million.

     The total cash requirements associated with the restructuring actions
discussed below are expected to be approximately $180 million in 1998 and a
total of $58 million in 1999 and beyond.  Several factors, including

                                       3


foreign currency fluctuations and negotiations with third parties, could cause
actual cash requirements to differ from expectations.

     During 1997, net cash used for continuing operations was $207.1 million.
For the year 1996, net cash used for continuing operations was $64.6 million.
In 1996, proceeds from the issuance of debt exceeded principal payments of debt
by $373.3 million.  During 1995, net cash used for continuing operations was
$412.4 million.  In 1995, discontinued operations provided cash of $658.3
million, primarily from the sale of the Company's defense systems business.

     In June 1997, the Company entered into a two-year $200 million revolving
credit facility replacing the prior one-year facility.  The facility includes
certain financial tests that must be met as conditions to a borrowing and
provides that no amounts may be outstanding under the facility for a minimum of
20 consecutive days in each quarter.  The facility may not be used to refinance
other debt.  The amount the Company may borrow at any given time is dependent
upon the amount of certain of its accounts receivable and inventory.

     The Company may require continued access to financing sources to meet its
cash requirements for debt service, restructurings and operating activities.
There can be no assurance that such access will always be available to the
Company or that the Company would be permitted to incur additional indebtedness
under its then existing set of restrictive covenants.

Net Losses and Restructurings

     The Company operates in an industry characterized by ongoing dramatic
changes, including, in the case of the Company, a shift from higher margin to
lower margin products and services.  In order to improve its operating results,
the Company has moved aggressively to realign its operations to reflect the
rapidly changing market for information processing products and services.  In
the fourth quarter of 1997, the Company took a one-time charge of $1.1 billion
against net income.  The charge included $127.0 million principally related to
the Company's 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
the Company's 8  1/4% convertible subordinated notes due 2006.  After this
charge, the Company reported a net loss of $853.6 million for 1997.  In 1995,
the Company reported a net loss of $624.6 million, which included a fourth
quarter pretax restructuring charge of $717.6 million, primarily relating to the
internal realignment of the Company into three operating units and covering work
force reductions, product and program discontinuances and consolidation of
office facilities and manufacturing capacity.  For the year ended December 31,
1996, the Company reported net income of $49.7 million.  In the fourth quarter
of 1996, the Company reversed certain reserves established under the 1995
restructuring plan, due to lower-than-anticipated costs for work force
reductions.  This reversal was offset by charges of $84 million relating to the
refocusing and discontinuance of certain products and programs.  The Company
recorded special pretax charges of $186.2 million in 1994, $1.2 billion in 1991,
$181.0 million in 1990 and $231.0 million in 1989.  Principally due to these
special charges, the Company had net losses of $1.4 billion in 1991, $436.7
million in 1990 and $639.3 million in 1989.  No assurance can be given that the
Company will not experience losses in the future.

                                       4


Systems Integration Contracts

     Certain of the Company's systems integration contracts are fixed-price
contracts under which the Company assumes the risk for the delivery of the
contracted services at an agreed-upon fixed price.  The Company has at times
experienced problems in performing certain of its fixed-price contracts on a
profitable basis and has provided periodically for adjustments to the cost to
complete such contracts.  In the fourth quarter of 1995, the Company 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, the Company recorded charges of approximately $25 million for
additional estimated contract costs identified during the quarter.  There can be
no assurance that the Company will not experience such contract performance
problems in the future, which problems could affect the Company's results of
operations.

Importance of International Operations

     Revenue from international operations accounted for approximately 60% of
the Company's total revenue in each of the last three years.  There is no
material concentration of revenues in any particular country.  Due to its
foreign operations, the Company is exposed to the effects of foreign exchange
rate fluctuations on the U.S. dollar.

     The Company uses foreign exchange forward contracts and options, generally
having maturities of less than nine months, to reduce such exposure.  Such
contracts and options are entered into for the sole purpose of hedging certain
transactional exposures.  The Company does not hold or issue financial
instruments for speculative trading purposes.  In addition to fluctuations in
foreign currency exchange rates, the Company's international business could be
affected by many factors beyond its control, such as instability of foreign
economies, U.S. and foreign government laws and policies affecting trade and
investment, and governmental changes.  Although the Company has not experienced
any significant problems in foreign countries arising from such factors, there
can be no assurance that such problems will not arise in the future.

No Dividends on Common Stock; Dividend Limitations

     The Company has not declared or paid any cash dividends on its Common Stock
since 1990 and does not anticipate declaring or paying dividends on the Common
Stock in the foreseeable future.  Certain of the Company's debt instruments and
credit facilities contain financial covenants which limit the payment of
dividends on the Company's capital stock.

                                USE OF PROCEEDS

     Except as may otherwise be set forth in the applicable Prospectus
Supplement, the Company will use the net proceeds from the sale of the Offered
Securities for general corporate purposes and to reduce or refinance
indebtedness.

                               RATIOS OF EARNINGS

     The following tables set forth the ratio of earnings to fixed charges and
the ratio of earnings to combined fixed charges and preferred stock dividends
for the Company for each of the years in the five-year period ended December 31,
1997.

     The ratio of earnings to fixed charges has been computed by dividing
earnings by fixed charges.  The ratio of earnings to combined fixed charges and
preferred stock dividends has been computed by dividing earnings by the sum of
fixed charges and preferred dividend requirements.  Earnings consist of income
(loss) from continuing operations before income taxes, extraordinary items and
changes in accounting principles minus undistributed earnings of associated
companies plus fixed charges.  Fixed charges consist of interest on all
indebtedness, amortization of debt issuance expenses and the portion of rental
expense representative of interest.

                       DESCRIPTION OF THE DEBT SECURITIES

     The following sets forth certain general terms and provisions of the
Indentures under which the Debt Securities are to be issued.  The particular
terms of a series of Debt Securities will be set forth in the Prospectus
Supplement or Prospectus Supplements relating to such Debt Securities.

     The Senior Debt Securities are to be issued under an Indenture (the "Senior
Indenture") between the Company and Bank of Montreal Trust Company, as Trustee
(the "Senior Trustee"), or under a substantially identical indenture with a
different trustee.  The Subordinated Debt Securities are to be issued under an
Indenture dated as of March 1, 1996 (the "Subordinated Indenture") between the
Company and The Bank of New York, as Trustee (the "Subordinated Trustee"), or
under a substantially identical indenture with a different trustee.  The Senior
Indenture and the Subordinated Indenture are sometimes referred to individually
as an "Indenture" and collectively as the "Indentures".  The Senior Trustee and
the Subordinated Trustee are sometimes referred to individually as a "Trustee"
and collectively as the "Trustees".  The following are brief summaries of
certain provisions of the Indentures.  The summaries do not purport to be
complete and are subject to the detailed provisions of the Indentures, copies of
which are filed as exhibits to the Registration Statement.  Capitalized terms
used in this Prospectus and not otherwise defined have the meanings specified in
the Indentures.

General

     The Indentures do not limit the aggregate principal amount of Debt
Securities which may be issued thereunder and provide that Debt Securities may
be issued from time to time in series.

     The Senior Debt Securities will be unsecured obligations of the Company and
will rank on a parity with all other unsecured and unsubordinated indebtedness
of the Company.  The Subordinated Debt Securities will be unsecured obligations
of the Company and will be subordinated in right of payment to all Senior
Indebtedness (as defined below in "Subordination of Debt Securities").

                                       6


     The applicable Prospectus Supplement will describe the following terms of
the Debt Securities offered thereby: (1) the title of such Debt Securities; (2)
whether such Debt Securities are Senior Debt Securities or Subordinated Debt
Securities; (3) any limit on the aggregate principal amount of such Debt
Securities; (4) the date or dates on which such Debt Securities may be issued
and are or will be payable; (5) the rate or rates per annum (which may be fixed
or variable) at which such Debt Securities will bear interest, if any, or the
method by which such rate or rates shall be determined, and the date or dates
from which such interest, if any, will accrue; (6) the date or dates on which
interest, if any, on such Debt Securities will be payable and the regular record
date or dates therefor; (7) the place or places where the principal of, and
premium, if any, and any interest on such Debt Securities will be payable; (8)
the period or periods within which, the price or prices at which, the currency
or currencies (including currency units) in which, and the terms and conditions
upon which such Debt Securities may be redeemed at the option of the Company;
(9) the obligation, if any, of the Company to redeem, to repay or purchase such
Debt Securities pursuant to any sinking fund or analogous provisions, upon the
happening of a specified event or at the option of a holder thereof, and the
period or periods within which, the price or prices at which and the terms and
conditions upon which such Debt Securities will be redeemed, repaid or purchased
pursuant to any such obligations; (10) whether such Debt Securities are to be
issued in whole or in part in the form of one or more Global Notes (as defined
under "Denominations, Registration and Transfer") and, if so, the identity of
the depositary, if any, for such Global Note or Notes; (11) if other than
dollars, the foreign currency or currencies (including currency units) in which
the principal of, and premium, if any, and any interest on such Debt Securities
shall or may be paid and, if applicable, whether at the election of the Company
and/or the holder, and the conditions and manner of determining the exchange
rate or rates; (12) any index used to determine the amount of payment of
principal of, and premium, if any, and any interest on such Debt Securities;
(13) whether such Debt Securities are convertible into shares of Common Stock
and the terms and conditions upon which any conversion will be effected,
including the conversion price, the conversion period and other conversion
provisions; (14) any addition to, or modification or deletion of, any Events of
Default or covenants provided for with respect to such Debt Securities and (15)
any other detailed terms and provisions of such Debt Securities which are not
inconsistent with the Indentures.

     Debt Securities may be issued at or above par or with an original issue
discount.  The applicable Prospectus Supplement will describe Federal income tax
consequences and other special considerations applicable to any Debt Securities
issued with original issue discount or above par.

     If the purchase price of any of the Debt Securities is denominated in one
or more foreign currencies or currency units, or if the principal of or any
premium or interest on any series of Debt Securities is payable in one or more
foreign currencies or currency units, the applicable Prospectus Supplement will
describe the restrictions, elections, Federal income tax considerations,
specific terms and other information with respect to such series and such
foreign currency or currency units.

Denominations, Registration and Transfer

     Debt Securities will be issued as registered securities either in
certificated form or in the form of one or more global securities (each a
"Global Note").  Debt Securities which are book-entry securities ("Book-Entry
Notes") will be issued as registered Global Notes.  Unless otherwise provided in
an applicable Prospectus Supplement with respect to a series of Debt Securities,
the Debt Securities will be issued in denominations of $1,000 or any integral
multiple thereof. One or more Global Notes will be issued in denominations or
aggregate denominations equal to the aggregate principal amount of outstanding
Debt Securities of the series to be represented by such Global Note or Notes.



                                       7


     Debt Securities of any series (other than a Book-Entry Note) may be
exchanged for other Debt Securities of the same series and of a like aggregate
principal amount and tenor of different authorized denominations.  Whenever any
such Debt Securities are surrendered for exchange, the Company shall execute,
and the Trustee shall authenticate and deliver, the Debt Securities which the
holder making the exchange is entitled to receive.

     Debt Securities (other than Book-Entry Notes) may be presented for
registration of transfer (with the form of transfer endorsed thereon duly
executed), at the office of the Security Registrar designated by the Company for
such purpose with respect to any series of Debt Securities and referred to in an
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the applicable Indenture.
Such transfer or exchange will be effected upon the Security Registrar being
satisfied with the documents of title and identity of the person making the
request.  The Company has appointed the Trustee under each Indenture as Security
Registrar for the applicable Debt Securities.

     For a discussion of restrictions on the exchange, registration and transfer
of Global Notes, see "Global Notes".

Payment and Paying Agents

     Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal of, and premium, if any, and any interest on Debt Securities will
be made at the office of such Paying Agent or Paying Agents as the Company may
designate from time to time, except that at the option of the Company payment of
any interest may be made (1) by check mailed to the address of the person
entitled thereto as such address shall appear in the Security Register or (2) by
wire transfer to an account maintained by the person entitled thereto.  Unless
otherwise indicated in an applicable Prospectus Supplement, payment of any
installment of interest on Debt Securities will be made to the person in whose
name such Debt Security is registered at the close of business on the regular
record date for such interest.

     Unless otherwise indicated in an applicable Prospectus Supplement, the
Trustee under the applicable Indenture will act as the Company's sole Paying
Agent through its principal office.  Any other Paying Agents in the United
States initially designated by the Company for the offered Debt Securities will
be named in an applicable Prospectus Supplement.  The Company may at any time
designate additional Paying Agents or rescind the designation of any Paying
Agent or approve a change in the office through which any Paying Agent acts,
except that the Company will be required to maintain a Paying Agent in each
Place of Payment for such series.

     All moneys paid by the Company to the Trustee or a Paying Agent for the
payment of principal of, and premium, if any, and any interest on any Debt
Security that remain unclaimed at the end of two years after such principal,
premium or interest shall have become due and payable will be repaid to the
Company, and the holder of such Debt Security or any coupon will thereafter look
only to the Company for payment thereof.

Global Notes

     The Debt Securities of a series may be issued in whole or in part in the
form of one or more Global Notes that will be deposited with, or on behalf of, a
depositary (a "Depositary") identified in the Prospectus Supplement relating to
such series.

     The specific terms of the depositary arrangement with respect to any Debt
Securities of a series will be described in the Prospectus Supplement relating
to such series.  The Company anticipates that the following provisions will
apply to all depositary arrangements.

 Book-Entry Notes

     Unless otherwise specified in an applicable Prospectus Supplement, Debt
Securities which are to be represented by a Global Note to be deposited with or
on behalf of a Depositary will be represented by a Global Note registered in the
name of such depositary or its nominee.  Upon the issuance of a Global Note, the
Depositary for

                                       8


such Global Note will credit, on its book-entry registration and transfer
system, the respective principal amounts of the Debt Securities represented by
such Global Note to the accounts of institutions that have accounts with such
Depositary or its nominee ("participants"). The accounts to be credited shall be
designated by the underwriters or agents of such Debt Securities, or by the
Company if such Debt Securities are offered and sold directly by the Company.
Ownership of beneficial interests in such Global Notes will be limited to
participants or persons that may hold interests through participants. Ownership
of beneficial interests by participants in such Global Notes will be shown on,
and the transfer of that ownership interest will be effected only through,
records maintained by the Depositary or its nominee for such Global Note.
Ownership of beneficial interests in Global Notes by persons that hold through
participants will be shown on, and the transfer of that ownership interest
within such participant will be effected only through, records maintained by
such participant. The laws of some jurisdictions require that certain purchasers
of securities take physical delivery of such securities in certificated form.
Such limits and such laws may impair the ability to transfer beneficial
interests in a Global Note.

     So long as the Depositary, or its nominee, is the registered owner of a
Global Note, such depositary or such nominee, as the case may be, will be
considered the sole owner or holder of the Debt Securities represented by such
Global Note for all purposes under the Indenture governing such Debt Securities.
Except as set forth below, owners of beneficial interests in such Global Notes
will not be entitled to have Debt Securities of the series represented by such
Global Note registered in their names, will not receive or be entitled to
receive physical delivery of Debt Securities of such series in certificated form
and will not be considered the owners or holders thereof under the applicable
Indenture.

     Payment of principal of, and premium, if any, and any interest on Debt
Securities registered in the name of or held by a Depositary or its nominee will
be made to the Depositary or its nominee, as the case may be, as the registered
owner or the holder of the Global Note representing such Debt Securities.  None
of the Company, any Trustee, any Paying Agent or the Security Registrar for such
Debt Securities will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests in a Global Note for such Debt Securities or for maintaining,
supervising or reviewing any records relating to such beneficial ownership
interests.

     The Company expects that the Depositary for Debt Securities of a series or
its nominee, upon receipt of any payment of principal, premium or interest in
respect of a Global Note, will credit immediately participants' accounts with
payments in amounts proportionate to their respective beneficial interests in
the principal amount of such Global Note as shown on the records of such
depositary or nominee.  The Company also expects that payments by participants
to owners of beneficial interests in such Global Note held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name", and will be the responsibility of such
participants.

     Unless and until it is exchanged in whole for Debt Securities in
certificated form, a Global Note may not be transferred except as a whole by the
Depositary for such Global Note to a nominee of such depositary or by a nominee
of such depositary to such depositary or another nominee of such depositary or
by such depositary or any such nominee to a successor of such depositary or a
nominee of such successor.  If a Depositary for Debt Securities is at any time
unwilling or unable to continue as depositary and a successor depositary is not
appointed by the Company within ninety days, the Company will issue Debt
Securities in certificated form in exchange for the Global Note or Notes
representing such Debt Securities.  In addition, the Company may at any time and
in its sole discretion determine not to have any Debt Securities in registered
form represented by one or more Global Notes and, in such event, will issue Debt
Securities in certificated form in exchange for the Global Note or Notes
representing such Debt Securities.  Further, if the Company so specifies with
respect to the Debt Securities of a series, an owner of a beneficial interest in
a Global Note representing Debt Securities of such series may, on terms
acceptable to the Company and the Depositary for such Global Note, receive Debt
Securities of such series in certificated form.  In any such instance, an owner
of a beneficial interest in a Global Note will be entitled to physical delivery
in certificated form of Debt Securities of the series represented by such Global
Note equal in principal amount to such beneficial interest and to have such Debt
Securities registered in its name.

                                       9


Certain Covenants Applicable to Senior Debt Securities

     Unless otherwise indicated in the applicable Prospectus Supplement with
respect to Senior Debt Securities of a series, Senior Debt Securities will have
the benefit of the following covenants contained in the Senior Indenture.
Unless otherwise indicated in the applicable Prospectus Supplement with respect
to Subordinated Debt Securities of a series, the Subordinated Debt Securities
will not have the benefit of such covenants.

 Limitation Upon Mortgages and Liens

     Neither the Company nor a Subsidiary will create or assume, except in favor
of the Company or a Wholly-Owned Subsidiary, any mortgage, pledge, lien or
encumbrance upon any Principal Manufacturing Property or any stock or
indebtedness of any Subsidiary without equally and ratably securing the
outstanding Senior Debt Securities.  For the purpose of providing such equal and
ratable security, the principal amount of outstanding Senior Debt Securities
issued with original issue discount shall be such portion of the principal
amount as may be specified in the terms of that series.  This limitation will
not apply to certain permitted encumbrances as described in the Senior
Indenture, including (1) purchase money mortgages entered into within specified
time limits; (2) liens existing on acquired property; (3) certain tax,
materialmen's, mechanics' and judgment liens, certain liens arising by operation
of law and certain other similar liens; (4) liens in connection with certain
government contracts; (5) certain mortgages, pledges, liens or encumbrances in
favor of any state or local government or governmental agency in connection with
certain tax-exempt financings; (6) pledges of customers' accounts or paper and
(7) mortgages, pledges, liens and encumbrances not otherwise permitted if the
sum of the indebtedness thereby secured plus the aggregate sales price of
property involved in certain sale and leaseback transactions does not exceed the
greater of $250,000,000 or 5% of Consolidated Stockholders' Equity.

  Limitation Upon Sale and Leaseback Transactions

     The Company and any Subsidiary will be prohibited from selling any
Principal Manufacturing Property owned on the date of the Senior Indenture with
the intention of taking back a lease thereof, other than a temporary lease (a
lease of not more than 36 months) with the intent that the use of the property
by the Company or such Subsidiary will be discontinued before the expiration of
such period, unless (1) the sum of the sale price of property involved in sale
and leaseback transactions not otherwise permitted plus all indebtedness secured
by certain mortgages, pledges, liens and encumbrances does not exceed the
greater of $250,000,000 or 5% of Consolidated Stockholders' Equity or (2) the
greater of the net proceeds of such sale or the fair market value of such
Principal Manufacturing Property (which may be conclusively determined by the
Board of Directors of the Company) are applied within 120 days to the optional
retirement of outstanding Senior Debt Securities or to the optional retirement
of other Funded Debt (as defined) of the Company ranking on a parity with
outstanding Senior Debt Securities.

 Certain Definitions

     Certain terms defined in the Senior Indenture and applicable to the
foregoing covenants are summarized below:

     "Consolidated Stockholders' Equity" means the total stockholders' equity of
the Company and its consolidated subsidiaries which, under generally accepted
accounting principles, would appear on a consolidated balance sheet of the
Company and its subsidiaries, excluding the separate component of stockholders'
equity attributable to foreign currency translation adjustments pursuant to
"Statement of Financial Accounting Standards No. 52-Foreign Currency
Translation" or any successor provision or principle of generally accepted
accounting principles.

     "Principal Manufacturing Property" means any manufacturing property located
within the United States of America (other than its territories or possessions)
owned by the Company or any Subsidiary, except for any manufacturing property
that, in the opinion of the Board of Directors, is not of material importance to
the business conducted by the Company and its Subsidiaries, taken as a whole.

                                       10


     "Subsidiary" means any corporation of which at least a majority of the
outstanding voting stock is owned by the Company or by other Subsidiaries, but
will not include any such corporation (an "Affiliated Corporation") which (1)
does not transact any substantial portion of its business or regularly maintain
any substantial portion of its operating assets in the United States; (2) is
principally engaged in financing sales or leases of merchandise, equipment or
services by the Company, a Subsidiary or another Affiliated Corporation; (3) is
principally engaged in holding or dealing in real estate or (4) is principally
engaged in the holding of stock in, and/or the financing of operations of,
Affiliated Corporations.

     "Wholly-Owned Subsidiary" means a Subsidiary of which all of the
outstanding voting stock (other than directors' qualifying shares) is at the
time, directly or indirectly, owned by the Company and/or by one or more Wholly-
Owned Subsidiaries.

Consolidation, Merger, Sale or Lease of Assets

     Each Indenture provides that the Company, without the consent of the
holders of any of the outstanding Debt Securities, may consolidate with or merge
into, or transfer or lease its assets substantially as an entirety to, any
corporation organized under the laws of any domestic jurisdiction, provided that
(1) the successor corporation assumes the Company's obligations under such
Indenture and the Debt Securities issued thereunder; (2) after giving effect to
the transaction, no Event of Default and no event which, after notice or lapse
of time, would become an Event of Default shall have occurred and be continuing
and (3) certain other conditions are met.

Events of Default

     The following are Events of Default under the Indentures with respect to
Debt Securities of any series: (1) failure to pay principal of or any premium on
any Debt Security of that series when due; (2) failure to pay any interest on
any Debt Security of that series when due, continued for 30 days; (3) failure to
deposit any sinking fund payment in respect of any Debt Security of that series
when due; (4) failure to perform any other covenant of the Company in the
applicable Indenture (other than a covenant included in such Indenture solely
for the benefit of a series of Debt Securities other than that series),
continued for 90 days after written notice as provided in the Indenture; (5)
certain events of bankruptcy, insolvency or reorganization and (6) any other
Event of Default provided with respect to Debt Securities of that series. Such
other Events of Default, if any, will be described in the Prospectus Supplement
relating to such Debt Securities.

     If any Event of Default with respect to Debt Securities of any series at
the time outstanding occurs and is continuing, either the Trustee or the holders
of at least 25% in aggregate principal amount of the outstanding Debt Securities
of that series may declare the principal amount (or, if the Debt Securities of
that series are issued with original issue discount, such portion of the
principal amount as may be specified in the terms of that series) of all the
Debt Securities of that series to be due and payable immediately.  At any time
after a declaration of acceleration with respect to Debt Securities of any
series has been made, but before a judgment or decree based on acceleration has
been obtained, the holders of a majority in aggregate principal amount of
outstanding Debt Securities of that series may, under certain circumstances,
rescind and annul such acceleration.

     The Indentures provide that, subject to the duty of the Trustee during
default to act with the required standard of care, the Trustee will be under no
obligation to exercise any of its rights or powers under the Indenture at the
request or direction of any of the holders, unless such holders shall have
offered to the Trustee reasonable indemnity.  Subject to such provisions for the
indemnification of the Trustee, the holders of a majority in aggregate principal
amount of the outstanding Debt Securities of any series will have the right to
direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or exercising any trust or power conferred on the
Trustee, with respect to the Debt Securities of that series.

     The Company is required to furnish the Trustees annually with a statement
as to the performance by the Company of certain of its obligations under the
Indentures and as to any default in such performance.

                                       11


Modification and Waiver

     Each Indenture provides that the Company and the Trustee may, without the
consent of any holders of Debt Securities, enter into supplemental indentures
for the purposes, among other things, of adding to the Company's covenants,
adding any additional Events of Default, establishing the form or terms of Debt
Securities or curing ambiguities or inconsistencies in such Indentures or making
other provisions; provided such action shall not adversely affect the interests
of the holders of any series of outstanding Debt Securities in any material
respect.

     Modifications of and amendments to the Indentures may be made by the
Company and the Trustee with the consent of the holders of a majority (66 2/3%
in the case of the Senior Indenture) in aggregate principal amount of the
outstanding Debt Securities of each series affected by such modification or
amendment; provided, however, that no such modification or amendment may,
without the consent of the holder of each outstanding Debt Security affected
thereby, (1) change the stated maturity of the principal of, or any installment
of principal or interest on, any Debt Security; (2) reduce the principal amount
of, or any premium or interest on, any Debt Security; (3) reduce the amount of
principal of Debt Securities issued with original issue discount payable upon
acceleration of the maturity thereof; (4) change the currency of payment of
principal of, or any premium or interest on, any Debt Security; (5) impair the
right to institute suit for the enforcement of any payment on or with respect to
any Debt Security; or (6) reduce the percentage in principal amount of
outstanding Debt Securities of any series, the consent of whose holders is
required for modification or amendment of the Indenture.

     The holders of a majority in aggregate principal amount of the outstanding
Debt Securities of each series may, on behalf of all holders of Debt Securities
of that series, waive any past default under the applicable Indenture with
respect to Debt Securities of that series, except a default in the payment of
the principal of or any premium or interest on any of the Debt Securities of
such series or in respect of a covenant or provision of such Indenture that
cannot, under the terms of such Indenture, be modified or amended without the
consent of the holders of each outstanding Debt Security affected thereby.

Defeasance

     Each Indenture provides that, if such provision is made applicable to the
Debt Securities of any series, the Company, at its option, will be discharged
from its obligations in respect of the outstanding Debt Securities of a series
(except for certain obligations to register the transfer or exchange of Debt
Securities of such series, convert Debt Securities of such series, replace
stolen, lost or mutilated Debt Securities of such series, maintain paying
agencies and hold moneys for payment in trust) or, in the case of Senior Debt
Securities, will not be subject to certain covenants applicable to the Debt
Securities of such series, in each case if the Company deposits with the
Trustee, in trust, money or government obligations which through the payment of
interest thereon and principal thereof in accordance with their terms will
provide money in an amount sufficient to pay all the principal of, and premium,
if any, and any interest on the Debt Securities of such series on the dates such
payments are due in accordance with the terms of such Debt Securities.  To
exercise any such option, the Company is required, among other things, to
deliver to the Trustee an opinion of counsel to the effect that the deposit and
related defeasance would not cause the holders of the Debt Securities of such
series to recognize income, gain or loss for United States income tax purposes
and the holders would be subject to Federal income tax on the same amounts, in
the same manner and at the same times as would have been the case if the deposit
and related defeasance had not occurred.

                                       12


Conversion Rights

     The terms on which and the prices at which Subordinated Debt Securities of
a series may be convertible into Common Stock will be set forth in the
Prospectus Supplement relating thereto. Such terms will include provisions as to
whether conversion is mandatory, at the option of the holder or at the option of
the Company.

Subordination Provisions

     Except as described in the applicable Prospectus Supplement, the
indebtedness evidenced by the Subordinated Debt Securities will be subordinate
in right of payment to all Senior Indebtedness (as hereinafter defined).

     No payment shall be made by the Company on account of principal of, and
premium, if any, or interest on the Subordinated Debt Securities or on account
of the purchase, redemption or other acquisition of the Subordinated Debt
Securities if there shall have occurred and be continuing any default in the
payment of principal, premium, if any, or interest on any Senior Indebtedness
continuing beyond the period of grace, if any, specified in the instrument
evidencing such Senior Indebtedness.

     Upon any distribution of assets of the Company upon any dissolution,
winding up, liquidation or reorganization, the payment of the principal of, and
premium, if any, and interest on the Subordinated Debt Securities is to be
subordinated to the extent provided in the Subordinated Indenture in right of
payment to the prior payment in full of all Senior Indebtedness. By reason of
this provision, in the event of the Company's dissolution or insolvency, holders
of Senior Indebtedness may receive more, ratably, and holders of Subordinated
Debt Securities may receive less, ratably, than the other creditors of the
Company.

     The foregoing subordination provisions will not prevent the occurrence of
any Event of Default under the Subordinated Indenture.

     The term "Senior Indebtedness" means the principal of, premium, if any, and
any interest on, and any other payment due pursuant to the terms of an
instrument (including, without limitation, fees, expenses, collection expenses
(including attorneys' fees), interest yield amounts, post-petition interest and
taxes) creating, securing or evidencing any of the following, whether
outstanding on the date of the Subordinated Indenture or thereafter incurred or
created:

     (1)  All indebtedness of the Company for money borrowed or constituting
     reimbursement obligations with respect to letters of credit (including
     indebtedness secured by a mortgage, conditional sales contract or other
     lien which is (A) given to secure all or a part of the purchase price of
     property subject thereto, whether given to the vendor of such property or
     to another, or (B) existing on property at the time of acquisition
     thereof);

     (2)  All indebtedness of the Company evidenced by notes, debentures, bonds
     or other securities;

     (3)  All indebtedness of others of the kinds described in either of the
     preceding clauses (1) or (2) assumed by or guaranteed in any manner by the
     Company or in effect guaranteed by the Company through an agreement to
     purchase, contingent or otherwise; and

     (4)  All renewals, deferrals, increases, extensions or refundings of and
     modifications to indebtedness of the kinds described in any of the
     preceding clauses (1), (2) or (3);

except (A) the Subordinated Debt Securities, (B) certain outstanding
subordinated indebtedness of the Company and (C) any indebtedness, renewal,
extension or refunding that, under the provisions of the instrument creating,
evidencing, or assuming or guaranteeing it, is not superior in right of payment
to the Subordinated Debt Securities or is subordinate by its terms in right of
payment to the Subordinated Debt Securities.

                                       13


     As of December 31, 1997, the Company had Senior Indebtedness (excluding
accrued interest and premium, if any) of approximately $1.6 billion. The amount
of Senior Indebtedness may change in the future. The Subordinated Indenture
contains no limitations on the incurrence of Senior Indebtedness.

Notices

     Notices to holders of Debt Securities will be given by mail to the
addresses of such holders as they appear in the Security Register.

Governing Law

     The Indentures and the Debt Securities will be governed by, and construed
in accordance with, the laws of the State of New York.

Concerning the Trustees

     Each Trustee, or its affiliates, has normal banking relationships with the
Company.  In addition, the Subordinated Trustee and Bank of Montreal, the parent
of the Senior Trustee, each participates as a lender in the Company's revolving
credit facility.  The Senior Trustee also serves as trustee under another
indenture with the Company pursuant to which unsecured senior debt securities
are currently outstanding.  Harris Trust Company of New York, an affiliate of
the Senior Trustee, serves as the Company's transfer agent.

                          DESCRIPTION OF CAPITAL STOCK

     The following descriptions do not purport to be complete and are subject
to, and qualified in their entirety by reference to, the more complete
descriptions thereof set forth in (1) the Company's Certificate of
Incorporation; (2) the Company's By-Laws and (3) the Rights Agreement (as
defined below), all of which are exhibits to the Registration Statement.

     The Company's authorized capital stock consists of 720,000,000 shares of
Common Stock, par value $.01 per share, and 40,000,000 shares of Preferred
Stock, par value $1 per share.

     As of March 31, 1998, there were approximately 251.4 million shares of
Common Stock outstanding, and the Company had reserved approximately 80.5
million additional shares of Common Stock for issuance pursuant to various
employee benefit plans and upon the conversion of outstanding shares of
Preferred Stock and other outstanding securities.

     The Board of Directors has authorized the issuance of 30.0 million shares
of Series A Cumulative Convertible Preferred Stock (the "Series A Preferred
Stock") and 1.5 million shares of Junior Participating Preferred Stock (the
"Junior Preferred Stock"). As of March 31, 1998 there were approximately 28.4
million shares of Series A Preferred Stock and no shares of Junior Preferred
Stock outstanding.

     The Series A Preferred Stock ranks prior to the Common Stock and the Junior
Preferred Stock as to payment of dividends and as to distribution of assets upon
liquidation, dissolution or winding up of the Company. Unless otherwise set
forth in the applicable Prospectus Supplement, each series of Preferred Stock
offered hereby will rank on a parity with each other such series and with the
Series A Preferred Stock.

Common Stock

 General

     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 of the Company from funds legally available
for that purpose; (2) have the exclusive right, except as otherwise may be
required by law, to vote for the

                                       14


election of directors and for all other purposes and (3) are entitled, upon any
liquidation, dissolution or winding up of the Company, to a pro rata
distribution of the assets and funds of the Company 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. The
Common Stock is traded on the New York Stock Exchange and prices are reported by
the New York Stock Exchange Composite Tape under the symbol UIS. Harris Trust
Company of New York is the transfer agent for the Common Stock.

 Dividend Limitations

     The Company 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.  In addition, the Company's most restrictive
outstanding debt instruments generally limit aggregate dividends paid on the
Company's capital stock since June 30, 1992 (other than $185 million paid in
respect of dividends in arrears) to an amount no greater than 50% of cumulative
consolidated net income since July 1, 1992, plus capital contributions and
proceeds of equity issuances, plus $150 million.

 Preferred Share Purchase Rights and Junior Participating Preferred Stock

     The Company has distributed to its stockholders one Preferred Share
Purchase Right (the "Rights") with respect to each outstanding share of Common
Stock pursuant to a Rights Agreement (the "Rights Agreement") dated as of March
7, 1986 between the Company and Harris Trust Company of New York, as Rights
Agent.  Each Right entitles the holder thereof, 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 such dates being called the "Distribution Date").  The
Rights could then begin trading separately from the shares of Common Stock.

     In the event that the Company 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 such transaction, would have a market
value of two times the exercise price of the Right. Alternatively, if a 20%
holder were to acquire the Company by means of a reverse merger in which the
Company 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 has acquired beneficial ownership of 20% of the
shares of Common Stock.  The Rights will expire on March 17, 2001 (the "Final
Expiration Date"), unless the Final Expiration Date is extended or unless the
Rights are earlier redeemed by the Company in accordance with their terms. At no
time will the Rights have any voting rights.

     The foregoing summary of the Rights does not purport to be complete and is
qualified in its entirety by reference to the Rights Agreement, which is an
exhibit to the Registration Statement.

     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

                                       15


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 (1) in the event of
a stock dividend on, or a subdivision, combination or reclassification of the
shares of Junior Preferred Stock; (2) as a result of the grant to holders of the
shares of Junior Preferred Stock of certain rights or warrants to subscribe for
shares of Junior Preferred Stock or of securities convertible into shares of
Junior Preferred Stock (at a price, or with a conversion price, respectively,
less than the then current market price for the shares of Junior Preferred
Stock) or (3) as a result of the distribution to holders of the shares of Junior
Preferred Stock of evidences of indebtedness or assets (excluding regular
periodic cash dividends at a rate not in excess of 125% of the rate of the last
cash dividend theretofore paid or dividends payable in shares of Junior
Preferred Stock) or of subscription rights or warrants (other than those
referred to above).  With certain exceptions, no adjustment in the purchase
price will be required until cumulative adjustments require an adjustment of at
least 1% in such purchase price.  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 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.  The Company will issue one Right with each share of Common Stock
issued prior to the Final Expiration Date unless, prior to such issuance, the
Rights are redeemed or become exercisable and transferable apart from the shares
of Common Stock.

     The Rights have certain anti-takeover effects.  The Rights may cause
substantial dilution to a person or group that attempts to acquire the Company
on terms that the Board of Directors determines are not in the best interests of
the Company's stockholders, except pursuant to an offer conditioned on a
substantial number of Rights being acquired.  The Rights should not interfere
with any merger or other business combination approved by the Board of Directors
since the Rights may be redeemed by the Company 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

     The Company 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, unless (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 resulted 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.

     The Company's Certificate of Incorporation and By-Laws contain certain
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 of the Company unless such takeover or change in control is
approved by the Board of Directors. Such provisions may also render the removal
of the current Board of Directors more difficult.

                                       16


     The Company's Certificate of Incorporation and By-Laws provide that the
Board of Directors shall consist of not less than 10 nor more than 20 directors
(subject to any rights of the holders of shares of Preferred Stock to elect
additional directors), with the exact number to be fixed by the Board of
Directors pursuant to a resolution adopted by a majority of the entire Board.
The Board of Directors is divided into three classes of directors, which classes
are as nearly equal in number as possible.  One class of directors is elected
each year for a term of three years. Directors may be removed from office only
for cause and only by the affirmative vote of the holders of at least 80% of the
voting power of all capital stock of the Company entitled to vote generally in
the election of directors (the "Voting Stock"), voting as a single class.
Subject to any rights of the holders of shares of Preferred 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.  Pursuant to the Certificate of Incorporation, advance notice of
stockholder nominations for the election of directors must be given in the
manner provided in the Company's By-Laws. The By-Laws provide that written
notice of the intent of a stockholder to make a nomination at a meeting of
stockholders must be delivered to the Secretary of the Company not less than 90
days prior to the date of the meeting, in the case of an annual meeting, and not
more than seven days following the date of notice of the meeting, in the case of
a special meeting.  The notice must contain certain background information about
the nominee and the number of shares of the Company's capital stock beneficially
owned by the nominee. The affirmative vote of the holders of 80% or more of the
voting power of the then outstanding shares of Voting Stock, voting as a single
class, is required to amend, alter or repeal the provisions of the Certificate
of Incorporation and the By-Laws discussed above.

     The Company's Certificate of Incorporation also provides that certain
mergers, consolidations, sales or other transfers of assets of, issuances or
reclassifications of securities of, or adoptions of plans of liquidation by the
Company (individually, a "Business Combination") must be approved by an
affirmative vote of the holders of 80% or more of the voting power of the then
outstanding shares of Voting Stock, voting as a single class, when such action
involves a person (an "Interested Stockholder") who beneficially owns more than
20% of the voting power of the then outstanding shares of Voting Stock, unless
certain 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 the holders of 80% or more of the voting power of the
then outstanding shares of Voting Stock, voting as a single class, is required
to amend, alter or repeal such provisions of the Certificate of Incorporation.

     Under the Certificate of Incorporation and By-Laws, except as otherwise
required by law and subject to the rights of the holders of shares of Preferred
Stock, stockholders may not call a special meeting of stockholders. Only the
Board of Directors, pursuant to a resolution adopted by a majority of the entire
Board, may call a special meeting of stockholders.  The General Corporation Law
of the State of Delaware 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, without prior
notice, and without a stockholder vote if a written consent or consents 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 action at a meeting of stockholders.  The Company's
Certificate of Incorporation requires that stockholder action be taken at a
meeting of stockholders and prohibits stockholder action by written consent.
The affirmative vote of the holders of 80% or more of the voting power of the
then outstanding shares of Voting Stock, voting as a single class, is required
to amend, alter or repeal the provisions of the Certificate of Incorporation and
By-Laws discussed above.

     The purpose of certain provisions of the Certificate of Incorporation and
By-Laws discussed above 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 provisions (1) through (3) is to help assure the continuity
and stability of the business strategies and policies of the Company and to
discourage certain types of transactions that involve an actual or threatened
change of control of the Company.  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 the Company to an unsolicited takeover proposal
that does not contemplate the acquisition of at least 80% of the voting power of
all of the Voting Stock or to an unsolicited proposal for the restructuring or
sale of all or part of the Company.

                                       17


     Such 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 certain business combinations involving the Company and a certain
type of stockholder which do not meet specified criteria or are not approved by
supermajority vote cannot be consummated without the approval of a majority of
those directors who are not affiliated with such stockholder, such 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 of the Company 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 such 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 appropriate alternatives for the
Company's stockholders.

     Such charter and by-law provisions are intended to encourage persons
seeking to acquire control of the Company 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 which would treat all stockholders in
substantially the same manner.  Such provisions may have the effect of
discouraging a third party from making an unsolicited tender offer or otherwise
attempting to obtain control of the Company, 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 such shares repurchased by
the Company at a premium, such provisions could tend to reduce the temporary
fluctuations in the market price of Common Stock caused by such accumulations.
Accordingly, stockholders of the Company could be deprived of certain
opportunities to sell their shares at a temporarily higher market price.

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

Preferred Stock

     The following description sets forth certain general terms and provisions
of the Preferred Stock to which any Prospectus Supplement may relate.  Certain
other terms of a particular series of Preferred Stock will be described in the
Prospectus Supplement relating to that series.  If so indicated in the
Prospectus Supplement, the terms of any such series may differ from the terms
set forth below.  The description of certain provisions of the Preferred Stock
set forth below and in any Prospectus Supplement does not purport to be complete
and is subject to and qualified in its entirety by reference to the Company's
Certificate of Incorporation and the Certificate of Designation relating to each
such series of Preferred Stock, which will be filed with the Commission in
connection with the offering of such series of Preferred Stock.

     Under the Company's Certificate of Incorporation, the Board of Directors
may, by resolution, establish series of Preferred Stock having such voting
powers, and such designations, preferences and relative, participating, optional
or other special rights, and qualifications, limitations or restrictions
thereof, as the Board of Directors may determine.

     The Preferred Stock offered hereby will have the dividend, liquidation,
redemption and voting rights set forth below unless otherwise provided in the
Prospectus Supplement relating to a particular series of Preferred Stock.
Reference is made to the Prospectus Supplement relating to the particular series
of Preferred Stock offered thereby for specific terms, including: (1) the
designation and stated value per share of such Preferred Stock and the number of
shares offered; (2) the amount of liquidation preference per share; (3) the
price at which such Preferred Stock will be issued; (4) the dividend rate (or
method of calculation), the dates on which dividends will be payable,

                                       18


whether such dividends will be cumulative or noncumulative and, if cumulative,
the dates from which dividends will commence to cumulate; (5) any redemption or
sinking fund provisions; (6) any conversion rights and (7) any additional
voting, dividend, liquidation, redemption, sinking fund and other rights,
preferences, privileges, limitations and restrictions.

     The Preferred Stock offered hereby will be issued in one or more series.
The holders of Preferred Stock will have no pre-emptive rights.  Preferred Stock
will be fully paid and nonassessable upon issuance against full payment of the
purchase price therefor.  Unless otherwise specified in the Prospectus
Supplement relating to a particular series of Preferred Stock, each series of
Preferred Stock will, with respect to dividend rights and rights on liquidation,
dissolution and winding up of the Company, rank prior to the Common Stock and
the Junior Preferred Stock (the "Junior Stock") and on a parity with the Series
A Preferred Stock and each other series of Preferred Stock offered hereby (the
"Parity Stock").

 Dividend Rights

     Holders of the Preferred Stock of each series will be entitled to receive,
when, as and if declared by the Board of Directors of the Company, out of funds
legally available therefor, cash dividends at such rates and on such dates as
are set forth in the Prospectus Supplement relating to such series of Preferred
Stock. Such rate may be fixed or variable or both.  Each such dividend will be
payable to the holders of record as they appear on the stock books of the
Company on such record dates as will be fixed by the Board of Directors of the
Company. Dividends on any series of the Preferred Stock may be cumulative or
noncumulative, as provided in the Prospectus Supplement relating thereto.  If
the Board of Directors of the Company fails to declare a dividend payable on a
dividend payment date on any series of Preferred Stock for which dividends are
noncumulative, then the right to receive a dividend in respect of the dividend
period ending on such dividend payment date will be lost, and the Company will
have no obligation to pay the dividend accrued for that period, whether or not
dividends are declared for any future period.  Dividends on shares of each
series of Preferred Stock for which dividends are cumulative will accrue from
the date set forth in the applicable Prospectus Supplement.

     The Preferred Stock of each series will include customary provisions (1)
restricting the payment of dividends or the making of other distributions on, or
the redemption, purchase or other acquisition of, Junior Stock unless full
dividends, including, in the case of cumulative Preferred Stock, accruals, if
any, in respect of prior dividend periods, on the shares of such series of
Preferred Stock have been paid and (2) providing for the pro rata payment of
dividends on such series and other Parity Stock when dividends have not been
paid in full upon such series and other Parity Stock.

     See "Certain Provisions of Outstanding Preferred Stock" for a description
of provisions of the Company's Series A Preferred Stock that could limit the
Company's ability to pay dividends on the Preferred Stock offered hereby.

                                       19


 Rights Upon Liquidation

     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, the holders of each series of Preferred Stock will be
entitled to receive out of assets of the Company available for distribution to
stockholders, before any distribution of assets is made to holders of Junior
Stock, liquidating distributions in the amount set forth in the Prospectus
Supplement relating to such series of Preferred Stock plus an amount equal to
accrued and unpaid dividends.  If, upon any voluntary or involuntary
liquidation, dissolution or winding up of the Company, the amounts payable with
respect to the Preferred Stock of any series and any Parity Stock are not paid
in full, the holders of the Preferred Stock of such series and of such Parity
Stock will share ratably in any such distribution of assets of the Company in
proportion to the full respective preferential amounts (which may include
accumulated dividends) to which they are entitled. After payment of the full
amount of the liquidating distribution to which they are entitled, the holders
of such series of Preferred Stock will have no right or claim to any of the
remaining assets of the Company.  Neither the sale of all or a portion of the
Company's assets nor the merger or consolidation of the Company into or with any
other corporation shall be deemed to be a dissolution, liquidation or winding
up, voluntarily or involuntarily, of the Company.

 Redemption

     The terms, if any, on which shares of a series of Preferred Stock may be
subject to optional or mandatory redemption will be set forth in the Prospectus
Supplement relating to such series.

 Conversion

     The terms, if any, on which shares of any series of Preferred Stock are
convertible into Common Stock will be set forth in the Prospectus Supplement
relating thereto.

 Voting Rights

     The holders of Preferred Stock of a series offered hereby will not be
entitled to vote except as indicated below or in the Prospectus Supplement
relating to such series of Preferred Stock or as required by applicable law.
Unless otherwise specified in the Prospectus Supplement relating to a particular
series of Preferred Stock, when and if any such series is entitled to vote, each
share in such series will be entitled to one vote.

     Unless otherwise specified in the related Prospectus Supplement, holders of
shares of a series of Preferred Stock will have the following voting rights. If,
on the date used to determine stockholders of record for any meeting of
stockholders of the Company at which directors are to be elected, dividends
payable on any series of Preferred Stock offered hereby and any other series of
Parity Stock are in arrears in an amount equal to at least six quarterly
dividends, the number of directors of the Company will be increased by two and
the holders of all such series of Preferred Stock, voting as a class without
regard to series, will be entitled to elect such two additional directors at
such meeting.  The affirmative vote or consent of the holders of at least a
majority of the outstanding shares of a series of Preferred Stock and any other
series of Parity Stock also being affected, voting as a single class without
regard to series, will be required for any amendment of the Company's
Certificate of Incorporation if the amendment would have a materially adverse
effect on the powers, preferences or special rights of such series. The
affirmative vote or consent of the holders of at least two-thirds of the
outstanding shares of a series of Preferred Stock and any other series of Parity
Stock, voting as a single class without regard to series, will be required to
authorize, create or issue, or increase the authorized amount of, any class or
series of capital stock ranking prior to such series of Preferred Stock as to
dividends or upon liquidation.

Certain Provisions of Outstanding Preferred Stock

     As of March 31, 1998, there were approximately 28.4 million shares of
Series A Preferred Stock outstanding.  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 the holder thereof, into 1.67 shares of Common

                                       20


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 until all accrued and unpaid dividends on such
Preferred Stock have been paid. When dividends are not paid in full on the
Series A Preferred Stock, all dividends paid upon shares of such series and
Parity Stock must be paid pro rata so that the amount of dividends paid per
share on the Series A Preferred Stock and the Parity Stock bear to each other
the same ratio that accrued dividends per share on such series and the Parity
Stock bear to each other.

                          DESCRIPTION OF THE WARRANTS

     The Company may issue Warrants for the purchase of Debt Securities,
Preferred Stock or Common Stock.  Warrants may be issued independently or

agreement (a "Warrant Agreement") to be entered into between the Company and a

                              PLAN OF DISTRIBUTION

     The Offered Securities may be sold to underwriters for public offering
pursuant to terms of offering fixed at the time of sale.  In addition, the
Offered Securities may be sold by the Company to other purchasers directly or
through agents.  Any such underwriter or agent involved in the offer and sale of
the Offered Securities will be named in an applicable Prospectus Supplement.

     Underwriters may offer and sell the Offered Securities at a fixed price or
prices, which may be changed, or from time to time at market prices prevailing
at the time of sale, at prices related to such prevailing market prices or at
negotiated prices.  The Company also may offer and sell the Offered Securities
in exchange for one or more of its outstanding issues of debt securities.  The
Company also may, from time to time, authorize underwriters acting as the
Company's agents to offer and sell the Offered Securities upon the terms and
conditions as shall be set forth in an applicable Prospectus Supplement.  In
connection with the sale of Offered Securities, underwriters may be deemed to
have received compensation from the Company in the form of underwriting
discounts or commissions and may also receive commissions from purchasers of
Offered Securities for whom they may act as agents.  Underwriters may sell
Offered Securities to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
underwriters and/or commissions (which may be changed from time to time) from
the purchasers for whom they may act as agents.

     Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in an applicable Prospectus Supplement.  Underwriters, dealers
and agents participating in the distribution of the Offered Securities may be
deemed to be underwriters, and any discounts and commissions received by them
and any profit realized by them on resale of the Offered Securities may be
deemed to be underwriting discounts and commissions under the Securities Act.
Underwriters, dealers and agents may be entitled, under agreements entered into
with the Company, to indemnification against and contribution toward certain
civil liabilities, including liabilities under the Securities Act, and to
reimbursement by the Company for certain expenses.

     If so indicated in an applicable Prospectus Supplement, the Company may
authorize agents, underwriters or dealers acting as the Company's agents to
solicit offers from certain institutional investors to purchase Offered
Securities from the Company at the public offering price set forth in the
Prospectus Supplement pursuant to Delayed Delivery Contracts ("Contracts")
providing for payment and delivery on a future date or dates specified therein.
There may be limitations on the minimum amount which may be purchased by any
such institutional investor or on the portion of the aggregate amount of the
particular Offered Securities which may be sold pursuant to such arrangements.
Institutional investors to which such offers may be made, when offered, include
commercial and savings banks, insurance companies, pension funds, investment
banks, educational and charitable institutions and such other institutions as
may be approved by the Company.  Each Contract will be subject to the approval
of the Company. Contracts will not be subject to any conditions except (1)
purchase shall not at the time of delivery be prohibited under the laws of any
jurisdiction in the United States to which the purchaser is subject and (2) if
the Offered Securities are being sold to underwriters, the Company shall have
sold to underwriters the total amount of the Offered Securities less the amount
covered by Contracts.  Agents or underwriters will have no responsibility in
respect of the delivery or performance of Contracts.

                                       22


                                 LEGAL MATTERS

certain legal matters in connection with the Offered Securities will be passed
upon for the Company by Harold S. Barron, Esq., Senior Vice President, General
Counsel and Secretary of the Company, and for any agents or underwriters by
Simpson Thacher & Bartlett.  As of March 31, 1998, Mr. Barron owned 70,295
shares (including 66,695 restricted shares and restricted share units) of Common
Stock and held options to purchase 229,000 shares of Common Stock.
