                                 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 foreign 

 4

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.

 5

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").

 7

        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.

 8

        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 

 9

Note, the Depositary for 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.

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.

 11

     "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. 

 12

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.

 13

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. 

 14

     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 

 15

may be required by law, to vote for the 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 with 

 16

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. 

 17

     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. 

 18

     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, 

 19

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. 

 20

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 Stock.  The 

 21

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

                          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 
together with Debt Securities, Preferred Stock or Common Stock offered by any 
Prospectus Supplement and may be attached to or separate from any such 
Securities.  Each series of Warrants will be issued under a separate warrant 
agreement (a "Warrant Agreement") to be entered into between the Company and a 
bank or trust company, as warrant agent (the "Warrant Agent").  The Warrant 
Agent will act solely as an agent of the Company in connection with the 
Warrants and will not assume any obligation or relationship of agency or trust 
for or with any holders or beneficial owners of Warrants.  The following 
summary of certain provisions of the Warrants does not purport to be complete 
and is subject to, and qualified in its entirety by reference to, the 
provisions of the Warrant Agreement that will be filed with the Commission in 
connection with the offering of such Warrants.

such Warrants shall commence and the date on which such right shall expire; 
(9) if applicable, the minimum or maximum amount of such Warrants that may be 

 22

exercised at any one time; (10) the currency or currency units in which the 
offering price, if any, and the exercise price are payable; (11) if

considerations; (12) the antidilution provisions of such Warrants, if any; 
(13) the redemption or call provisions, if any, applicable to such Warrants; 
and (14) any additional terms of the Warrants, including terms, procedures,

                            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.

 23
                                 LEGAL MATTERS

     Unless otherwise indicated in an accompanying Prospectus Supplement, 
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.

All of the amounts are estimated except for the Securities and Exchange 
Commission registration fee.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS

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

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

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

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

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

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

     The Certificate of Incorporation also provides that each person who was 
or is made a party to, or is involved in, any action, suit or proceeding by 
reason of the fact that he or she is or was a director or officer of the 
Company (or was serving at the request of the Company as a director, officer, 
employee or agent for another entity) shall be indemnified and held harmless 
by the Company, to the fullest extent authorized by the DGCL, as in effect 
(or, to the extent indemnification is broadened, as it may be amended) against 
all expense, liability or loss reasonably incurred by such person in 
connection therewith.  The Certificate of Incorporation further provides that 
such rights to indemnification are contract rights and shall include the right 
to be paid by the Company the expenses incurred in defending the proceedings 
specified above, in advance of their final disposition, provided that, if the 
DGCL so requires, such payment shall only be made upon delivery to the Company 
by the indemnified party of an undertaking to repay all amounts so advanced if 

 II-2

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

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

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

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

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

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

ITEM 16. EXHIBITS

     See Index to Exhibits.

ITEM 17. UNDERTAKINGS

     The undersigned registrant hereby undertakes:

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

 II-3

(i)  To include any prospectus required by Section 10(a)(3) of the Securities 
Act of 1933 (the "Securities Act"), unless the information required to be 
included in such post-effective amendment is contained in a periodic report 
filed by the registrant pursuant to Section 13 or Section 15(d) of the 
Securities Exchange Act of 1934 (the "Exchange Act") and incorporated herein 
by reference; 

(ii)  To reflect in the prospectus any facts or events arising after the 
effective date of the Registration Statement (or the most recent post-
effective amendment thereof) which, individually or in the aggregate, 
represent a fundamental change in the information set forth in the 
Registration Statement, unless the information required to be included in such 
post-effective amendment is contained in a periodic report filed by the 
registrant pursuant to Section 13 or Section 15(d) of the Exchange Act and 
incorporated herein by reference; 

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

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

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

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

(5)  That, for purposes of determining any liability under the Securities Act, 
the information omitted from the form of prospectus filed as part of this 
Registration Statement in reliance upon Rule 430A and contained in the form of 
prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) 
under the Securities Act shall be deemed to be part of this Registration 
Statement as of the time it was declared effective; and 

(6)  That, for the purpose of determining any liability under the Securities 
Act, each post-effective amendment that contains a form of prospectus shall be 
deemed to be a new registration statement relating to the securities offered 
therein, and the offering of such securities at that time shall be deemed to 
be the initial bona fide offering thereof. 

     Insofar as indemnification for liabilities arising under the Securities 
Act may be permitted to directors, officers and controlling persons of the 
registrant pursuant to the provisions described in Item 15 above, or 
otherwise, the registrant has been advised that in the opinion of the 
Securities and Exchange Commission such indemnification is against public 
policy as expressed in the Securities Act and is, therefore, unenforceable. In 
the event a claim for indemnification against such liabilities (other than the 
payment by the registrant of expenses incurred or paid by a director, officer 
or controlling person of the registrant in the successful defense of any 
action, suit or proceeding) is asserted against the registrant by such 
director, officer or controlling person in connection with the Securities 
being registered, the registrant will, unless in the opinion of its counsel 
the matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnification by it is 
against public policy as expressed in the Securities Act and will be governed 
by the final adjudication of such issue.

Pennsylvania, on May 4, 1998.
