OTHER PROVISIONS:



         USX CORPORATION, a corporation duly organized under the laws of the
State of Delaware (herein called the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to [INSERT IF THE SECURITY IS TO BE A GLOBAL
SECURITY -- Cede & Co., as nominee for The Depository Trust Company]
[________________________________________________________________], or
registered assigns, the principal amount specified above (any currency or
currency unit other than U.S. dollars being hereinafter referred to as a
"Specified Currency") on the Stated Maturity specified above and to pay
interest thereon (computed, unless a different Computation Period is specified
above, on the basis of a 360-day year of twelve 30-day months) from and
including the Date of Issue specified above (the "Date of Issue") or from and
including the most recent Interest Payment Date to which interest on this
Security (or any Predecessor Security) has been paid or duly provided for to,
but excluding, the Interest Payment Date, on the Interest Payment Date(s)
specified above in each year (each an "Interest Payment Date") and at Maturity,
at the rate per annum equal to the Interest Rate specified above, until the
principal hereof is paid or duly made available for payment; provided, however,
that, unless the Holder hereof is entitled to make, and has made, a Specified
Currency Payment Election (as hereinafter defined) with respect to one or more
such payments, the Company will make all such payments in U.S. dollars in
amounts determined as set forth on the reverse hereof.  If any Interest Payment
Date or the Maturity shown on the face hereof falls on a day that is not a
Market Day, the related payment of principal, premium, if any, or interest will
be made on the next succeeding Market Day as if made on the date such payment
was due, and no interest will accrue on the amount so payable for the period
from and after such Interest Payment Date or Maturity, as the case may be.  The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in such Indenture, be paid to the Person in
whose name this Security (or one or more predecessor Securities) is registered
at the close of business on the fifteenth day next preceding such Interest
Payment Date, unless a different Regular Record Date is specified above (the
"Regular Record Date"); provided, however, that interest payable at Maturity
will be payable to the person to whom principal shall be payable; and provided,
further, that if the Date of Issue is after a Regular Record Date and before
the next succeeding Interest Payment Date the first

payment of interest shall be payable on the second Interest Payment Date
following the Date of Issue to the person in whose name this Security (or one
or more Predecessor Securities) is registered at the close of business on the
Regular Record Date immediately preceding such Interest Payment Date.  Any such
interest which is payable, but not so punctually paid or duly provided for, on
any Interest Payment Date will forthwith cease to be payable to the Holder on
such Regular Record Date and such Defaulted Interest may either be paid to the
Person in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on a Special Record Date for the payment of
such Defaulted Interest to be fixed by the Trustee, notice whereof shall be
given to Holders of Securities of this series not less than 15 days prior to
such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which this
Security may be listed, and upon such notice as may be required by such
exchange, all as more fully provided in said Indenture.

         Payment of the principal of (and premium, if any) and interest on this
Security will be made at the principal corporate trust office of the Issuing
and Paying Agent in the Borough of Manhattan, The City of New York, or such
other office or agency of the Company maintained by it for that purpose in the
Borough of Manhattan, The City of New York, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts; provided, however, that payment of the principal
of (and premium, if any) and interest on this Security due will be made in
immediately available funds at such corporate trust office or such other office
or agency if this Security is presented to the Paying Agent in time for the
Paying Agent to make such payments in such funds in accordance with its normal
procedures; and provided, further, that, at the option of the Company, payment
of interest (other than interest payable at Maturity) may be made by check
mailed to the address of the Holder as such address shall appear in the
Security Register; and provided, further, that if this Security is denominated
in a Specified Currency, the Holder hereof is entitled to make, and has made, a
Specified Currency Payment Election with respect to such payments, the Exchange
Rate Agent is able to convert such payments as provided below and the Specified
Currency is not unavailable due to the imposition of exchange controls or other
circumstances beyond the control of the Company, then (i) the payment of
interest on this Security will be made in the Specified Currency (or, if such
Specified Currency is not at the time of such payment legal tender for the
payment of public and private debts, in such other coin or currency of the
country which issued such Specified Currency as at the time of such payment is
legal tender for the payment of such debts) by check drawn upon a bank office
located outside the United States and mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register, and
(ii) the payment of principal (and premium, if any) and interest due at
Maturity will be made in such Specified Currency (or, if applicable, such other
coin or currency) by wire transfer of immediately available funds to an account
maintained by the Holder hereof with a bank office located in the country which
issued the Specified Currency upon presentation of this Security to the Paying
Agent in time for such wire transfer to be made by the Paying Agent in
accordance with its normal procedures.  Unless otherwise specified above, if
this Security is denominated in a Specified Currency the Holder hereof may
elect to receive payments of principal of (and premium, if any) and interest in
such Specified Currency (a "Specified Currency Payment Election") by delivery
of a written request (including, in the case of an election with respect to
payments at Maturity, appropriate wire transfer instructions to be received by
the Issuing and Paying Agent no later than the relevant Record Date) to the
Issuing and Paying Agent at its principal corporate trust office referred to
above on or prior to the relevant Regular Record Date or the sixteenth day
prior to Maturity, as the case may be.  Such request may be in writing (mailed
or hand delivered) or by facsimile transmission.  A Holder of a Security
denominated in a Specified Currency may elect to receive payment in the
Specified Currency for all principal (and premium, if any) and interest
payments and need not file a separate election for each payment.  Such election
will remain in effect until revoked by written notice to the Issuing & Paying
Agent, but written notice of any





                                      -3-

such revocation must be received by the Issuing & Paying Agent on or prior to
the relevant Regular Record Date or the sixteenth day prior to Maturity, as the
case may be.

         Reference is hereby made to the further provisions of this Security
set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual signature, this
Security shall not be entitled to any benefit under the Indenture or be valid
or obligatory for any purpose.

         IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed by manual or facsimile signature under its corporate seal.

                         [Form of Reverse of Security]

         This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or
more series under the Indenture, dated as of March 15, 1993 (herein called the
"Indenture"), between the Company and PNC Bank, National Association, as
Trustee (herein called the "Trustee", which term includes any successor trustee
under the Indenture), to which Indenture and all indentures supplemental
thereto reference is hereby made for a statement of the respective rights,
limitations of rights, duties and immunities thereunder of the Company, the
Trustee and the Holders of the Securities and of the terms upon which the
Securities are, and are to be, authenticated and delivered.  This Security is
one of the series designated on the face hereof, limited to an aggregate
principal amount not to exceed $750,000,000 (or if Securities of this series
are to be Original Issue Discount Securities or are to be denominated in one or
more Specified Currencies or with the amount payable in respect of principal or
any premium or interest to be determined by reference to the value, rate or
price of one or more specified indices ("Indexed Securities"), such principal
amount as shall result in an aggregate initial offering price of Securities
equivalent to not more than $750,000,000), which amount may be increased at the
option of the Company if in the future it determines that it may wish to sell
additional Securities, which may be offered or sold either in the United States
or outside the United States or both simultaneously.  Except as may be
otherwise stated on the face hereof, the Securities of this series are issuable
only as registered Securities, without coupons, in denominations of $100,000
and integral multiples of $1,000 in excess thereof (or in the case of
Securities denominated in a Specified Currency, in such minimum denomination
not less than the equivalent of $100,000 in such Specified Currency on the
basis of the noon buying rate for cable transfers in The City of New York as
certified for customs purposes by (or, if not so certified, as otherwise
determined by) the Federal Reserve Bank of New York (the "Market Exchange
Rate") for such Specified Currency on the date the Company agrees to issue such
Security, and such greater denomination or denominations as shall be set forth
on the face thereof).  The Securities of this series may be issued from time to
time in various principal amounts and currencies or currency units, may mature
at different times, may bear interest at different rates, may be subject to
different redemption provisions, if any, and may otherwise vary.  As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

         The Securities are general, direct, unconditional and unsecured
obligations of the Company.

         If this Security is designated on the face hereof as an Original Issue
Discount Security, then, notwithstanding anything to the contrary contained in
this Security, upon the redemption or acceleration of Maturity of this Security
there shall be payable, in lieu of the principal amount due at the Stated
Maturity hereof, as specified on the face hereof, an amount equal to the
Amortized Face Amount of this Security.  The "Amortized Face Amount" shall be
the amount equal to (a) the issue price of this Security (as defined below),
plus (b) that portion of the difference between the issue price and the
principal amount of this Security that has been amortized at the Stated Yield
(as defined below) of this Security (computed in accordance with generally
accepted United States bond yield computation principles) at the date as of
which the Amortized Face Amount is calculated, but in no event shall the
Amortized Face Amount exceed the principal amount of this Security due at the
Stated Maturity hereof.  As used in the previous sentence "issue price" means
the principal amount due at the Stated Maturity hereof less the Total Amount of
OID of this Security specified on the face hereof and the "Stated Yield" means
the Yield to Maturity specified on the face hereof (or if not so specified, the
yield to maturity compounded semi-annually and computed in accordance with
generally accepted United States bond yield computation principles) for the
period from the Date of Issue to the Stated Maturity on the basis of the issue
price and such principal amount.

         If this Security is denominated in a Specified Currency, unless the
Holder hereof is entitled to make, and has made, a Specified Currency Payment
Election with respect to such payments as provided on the face hereof, the
Holder of this Security shall receive payments of principal (and premium, if
any) and interest in U.S. dollars at an exchange rate based on the highest bid
quotation in The City of New York received by the Exchange Rate Agent (who,
unless otherwise specified on the face hereof, shall be the Issuing and Paying
Agent) at approximately 11:00 A.M., New York City time, on the second Market
Day with respect to this Security preceding the applicable payment date from
three recognized foreign exchange dealers (one of which may be the Exchange
Rate Agent) selected by the Exchange Rate Agent and approved by the Company for
the purchase by the quoting dealer of the Specified Currency for U.S. dollars
for settlement on such payment date in the aggregate amount of such Specified
Currency payable to all Holders of Securities of this series denominated in
such Specified Currency and scheduled to receive U.S. dollar payment on such
payment date and at which the applicable dealer commits to execute a contract.
"Market Day" means (a) with respect to any Security (unless otherwise provided
in this definition), any Business Day, (b) with respect to Securities that bear
interest on the basis of the London Interbank Offered Rate as determined from
time to time, any Business Day that is also a London Banking Day ("London
Banking Day" means any day on which dealings in deposits in U.S. dollars are
transacted in the London interbank market), (c) with respect to Securities
denominated in a Foreign Currency (other than Securities denominated in
European Currency Units ("ECUs")), any Business Day that, in the principal
financial center of the country of the Specified Currency, is not a day on
which banking institutions generally are authorized or obligated by law or
executive order to close and (d) with respect to Securities denominated in
ECUs, any Business Day that is also designated as an ECU settlement day by the
ECU Banking Association in Paris or otherwise generally regarded in the ECU
interbank market as a day in which payments in ECUs are made.  All currency
exchange costs incurred by the Company in converting a Specified Currency into
U.S. dollars in order to make payments hereon will be borne by the Holder of
this Security by deductions from such payments.  If such bid quotations are not
available, or if a Specified Currency Payment Election has been made with
respect to such payments, payments will be made in the Specified Currency (or,
if such Specified Currency is not at the time of such payment legal tender for
the payment of public and private debts, such other coin or currency of the
country which issued such Specified Currency as at the time of such payment is
legal tender for the payment of such debts); provided, however, that if such
Specified Currency (or, if applicable, such other coin or currency) is
unavailable due to the imposition of exchange controls or other circumstances
beyond the Company's control, the Company will be entitled to make payments in
U.S.  dollars on the basis of the Market Exchange Rate for such Specified
Currency (or, if applicable, such other coin or currency) on the second Market
Day prior to such payment or, if such Market Exchange Rate is not then
available, on the basis of the most recently available Market Exchange Rate or
as otherwise indicated hereon.

         If one or more Redemption Dates (or ranges of Redemption Dates) is
specified on the face hereof, this Security is subject to redemption upon not
less than 30 days' notice by mail, on any such date (or during any such range),
as a whole, or from time to time in part, at the election of the Company, at a
Redemption Price determined as provided in the next succeeding sentence,
together with accrued interest to the Redemption Date, but interest instalments
whose Stated Maturity is on or prior to the Redemption Date will be payable to
the Holder hereof (or one or more Predecessor Securities) of record at the
close of business on the Regular Record Dates referred to on the face hereof,
all as provided in the Indenture.  If applicable, the "Redemption Price" for
any such redemption shall be the amount determined by multiplying the
Redemption Percentage specified on the face hereof with respect to the relevant
Redemption Date (or range of such dates), by the portion of the principal
amount hereof (or, if this Security is an Original Issue Discount Security, the
portion of the Amortized Face Amount hereof) to be redeemed; provided, however,
that in no event shall the Redemption Price be less than 100% of the portion of
the principal amount hereof (or, if





                                      -6-
   7
this Security is an Original Issue Discount Security, the portion of the
Amortized Face Amount hereof) to be redeemed.

         Notice of redemption having been given as aforesaid, this Security (or
the portion of the principal amount hereof so to be redeemed) shall, on the
Redemption Date, become due and payable at the Redemption Price herein
specified, and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued interest) shall cease to bear
interest.  In the case of any partial redemption at the election of the Company
of Securities of this series, the Securities of a particular tenor to be
redeemed shall be selected by the Trustee not more than 45 days prior to the
Redemption Date by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of portions of the
principal amount of Securities.  In the event of any redemption of this
Security in part only, a new Security or Securities of this series of like
tenor for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof, provided that such unredeemed
portion shall not be less than the minimum denomination of this Security.

         If one or more Redemption Dates (Option of Holder) (or ranges of such
dates) is specified on the face hereof, this Security is subject to redemption
on any such date (or during any such range) or, if such date is not a Market
Day, on the first Market Day following such date, as a whole or from time to
time in part, at the election of the Holder hereof, at a Redemption Price
determined as provided above together with accrued interest to the Redemption
Date, but interest instalments whose Stated Maturity is on or prior to the
Redemption Date will be payable to the Holder hereof of record at the close of
business on the Regular Record Date referred to on the face hereof, all as
provided in the Indenture.  Such election shall be effected by the Holder
hereof delivering to the Company at the principal corporate trust office of the
Issuing & Paying Agent in the Borough of Manhattan, The City of New York, or
such other office or agency of the Company maintained by it for that purpose in
the Borough of Manhattan, The City of New York, not less than 30 nor more than
60 days prior to the date on which this Security is to be redeemed, or during
such other Notice Period specified on the face hereof, a notice requesting such
redemption in the form described below and specifying the date upon which this
Security is to be redeemed.  Any notice given by a Holder pursuant to this
paragraph shall consist of either (i) this Security with the form entitled
"Option to Elect Redemption" set forth at the end of this Security duly
completed or (ii) a telegram, facsimile transmission or a letter from a member
of a national securities exchange, or the National Association of Securities
Dealers, Inc. or a commercial bank or trust company in the United States
setting forth the name of the Holder hereof, the principal amount of this
Security, the principal amount of this Security to be redeemed, the certificate
number or a description of the terms of this Security, a statement that the
option to elect redemption is being exercised thereby and a guarantee that this
Security, together with the duly completed form entitled "Option to Elect
Redemption" below, will be received by the Issuing & Paying Agent not later
than the fifth Market Day after the date of such telegram, facsimile
transmission or letter; provided, however, that such telegram, facsimile
transmission or letter shall only be effective if this Security and form duly
completed are received by such Issuing & Paying Agent by such fifth Business
Day.  Exercise of the redemption option by the Holder hereof will be
irrevocable.  If applicable, the "Redemption Price" for any such redemption
shall be determined by multiplying the Redemption Percentage (Option of Holder)
specified on the face hereof with respect to the relevant Redemption Date
(Option of Holder) (or range of such dates) by the portion of the principal
amount hereof (or, if this Security is an Original Issue Discount Security, the
portion of the Amortized Face Amount hereof) to be redeemed, together with
interest accrued thereon to the Redemption Date; provided, however, that in no
event shall the Redemption Price be less than 100% of the portion of the
principal amount hereof (or, if this Security is an Original Issue Discount
Security, the portion of the Amortized Face Amount hereof) to be redeemed.

         The Indenture contains provisions for defeasance and covenant
defeasance at any time of the entire indebtedness on this Security upon
compliance by the Company with certain conditions set forth therein.

         If an Event of Default with respect to the Securities of this series
shall occur and be continuing, the principal of the Securities of this series
(or, in the case of Original Issue Discount Securities the Amortized Face
Amount thereof) may be declared due and payable in the manner and with the
effect provided in the Indenture.  Upon payment (i) of the amount of principal
so declared due and payable and (ii) of interest on any overdue principal and
overdue interest (in each case to the extent that the payment of such interest
shall be legally enforceable), all of the Company's obligations in respect of
the payment of the principal of and interest, if any, on the Securities of this
series shall terminate.

         The Indenture permits, with certain exceptions as therein provided,
the amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66 2/3% in principal amount of the Securities at
the time outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange therefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

         No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any)
and interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

         As provided in the Indenture and subject to certain limitations
therein set forth, the transfer of this Security is registrable in the Debt
Security register, upon surrender of this Security for registration of transfer
at the office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Security are payable, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Debt Security registrar duly executed by, the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new
Securities of this series and of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

         As provided in the Indenture and subject to certain limitations
therein set forth, the Securities of this series are exchangeable for a like
aggregate principal amount of Securities of this series and of like tenor of a
different authorized denomination, as requested by the Holder surrendering the
same.  In the event of any redemption at the election of the Company, the
Trustee shall not be required to exchange or register a transfer of (a) any
Securities of this series of like tenor for a period of fifteen days next
preceding the mailing of any notice of redemption, or (b) any Security
selected, called or being called for redemption except, in the case of any
Security to be redeemed in part, the portion thereof not to be so redeemed.
Following the exercise of a redemption option by the Holder hereof, the Trustee
shall not be required to issue, register the transfer of or exchange that
portion of this Security with respect to which such option has been exercised.

         No service charge shall be made for any such registration of transfer
or exchange, but the Company may require payment of a sum sufficient to cover
any tax or other governmental charge payable in connection therewith.

         The Securities of this series may be issued in the form of one or more
Global Securities to The Depository Trust Company as depositary for the Global
Securities of this series (the "Depositary") or its nominee and registered in
the name of the Depositary or such nominee.  If the face of this Security
contains a legend indicating that this Security is a Global Security so
registered, the transfer and exchange hereof is subject to the additional
limitations set forth in such legend.

         Prior to due presentment of this Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Security be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

         All terms used in this Security which are defined in the Indenture
shall have the meanings assigned to them in the Indenture.

       USX CORPORATION, a corporation duly organized under the laws of the
State of Delaware (herein called the "Company", which term includes any

received, hereby promises to pay to [INSERT IF THE SECURITY IS TO BE A GLOBAL

[__________________________________________________________], or registered
assigns, the principal amount specified above (any currency or currency unit
other than U.S. dollars being hereinafter referred to as a "Specified
Currency") on the Stated Maturity specified above and to pay interest thereon,
from and including the Date of Issue specified above (the "Date of Issue") or
from and including the most recent Interest Payment Date to which interest on
this Security (or any Predecessor Security) has been paid or duly provided for
to, but excluding, the Interest Payment Date (as hereinafter defined), at a

hereof) following the Date of Issue and thereafter at a

rate determined in accordance with the provisions on the reverse hereof under
the heading "Determination of Commercial Paper Rate", "Determination of Prime
Rate", "Determination of CD Rate", "Determination of Federal Funds Rate",
"Determination of LIBOR" or "Determination of Treasury Rate", depending upon
whether the Interest Rate Basis specified above is Commercial Paper Rate, Prime
Rate, CD Rate, Federal Funds Rate, LIBOR or Treasury Rate, until the principal
hereof is paid or duly made available for payment; provided, however, that,
unless the Holder hereof is entitled to make, and has made, a Specified
Currency Payment Election (as hereinafter defined) with respect to one or more
such payments, the Company will make all such payments in respect of this
Security in U.S. dollars in amounts determined as set forth on the reverse
hereof.  Such interest shall be payable by the Company monthly, quarterly,
semi- annually or annually as specified above under "Interest Payment Period"
and, unless otherwise specified above under "Interest Payment Date(s)", such
interest shall be payable by the Company on the third Wednesday of the month or
months specified above under "Interest Payment Month(s)" in each year (each
date so specified above or, if none is so specified, determined as herein
provided, an "Interest Payment Date") and at Maturity.  If any Interest Payment
Date shown on the face hereof would otherwise be a day that is not a Market
Day, the Interest Payment Date shall be postponed to the next day that is a
Market Day, except that if the rate of interest on this Security shall be
determined in accordance with the provisions of the heading "Determination of
LIBOR" above, and such Market Day is in the next succeeding calendar month,
such Interest Payment Date shall be the immediately preceding Market Day.  If
the Maturity of this Security would otherwise be a day that is not a Market
Day, the payment of principal (and premium, if any) and interest may be made on
the next succeeding Market Day, and no interest on such payment will accrue
from and after the Maturity.  The interest so payable, and punctually paid or
duly provided for, on any such Interest Payment Date will be paid to the Person
in whose name this Security (or one or more Predecessor Securities) is
registered at the close of business on the fifteenth day (whether or not a
Market Day) next preceding such Interest Payment Date, unless a different
Regular Record Date is specified above (the "Regular Record Date"); provided,
however, that interest payable at Maturity will be payable to the Person to
whom principal shall be payable; and provided, further, that if the Date of
Issue is after a Regular Record Date and before the next succeeding Interest
Payment Date the first payment of interest shall be payable on the second
Interest Payment Date following the Date of Issue to the Person in whose name
this Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date immediately preceding such
Interest Payment Date.  Any such interest which is payable, but not so
punctually paid or duly provided for, on any Interest Payment Date will
forthwith cease to be payable to the Holder on such Regular Record Date and
such Defaulted Interest may either be paid to the Person in whose name this
Security (or one or more predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
of this series not less than 15 days prior to such Special Record Date, or be
paid at any time in any other lawful manner not inconsistent with the
requirements of any securities exchange on which this Security may be listed,
and upon such notice as may be required by such exchange, all as more fully
provided in said Indenture.
        
       Payment of the principal of (and premium, if any) or interest on this
Security will be made at the principal corporate trust office of the Issuing
and Paying Agent in the Borough of Manhattan, The City of New York, or such
other office or agency of the Company maintained by it for that purpose in the
Borough of Manhattan, The City of New York, in such coin or currency of the
United States of America as at the time of payment is legal tender for payment
of public and private debts; provided, however, that payment of the principal
of (and premium, if any) and interest on this Security due will be made in
immediately available funds at such corporate trust office or such other office
or agency if this Security is presented to the Paying Agent in time for the
Paying Agent to make such payments in accordance with its normal procedures;
and provided, further, that at the option of the Company payment of interest
(other than interest payable at Maturity) may be made by check and mailed to
the address of the Holder as such address shall appear in the Security
Register; and provided, further, that

if this Security is denominated in a Specified Currency, the Holder hereof is
entitled to make, and has made, a Specified Currency Payment Election with
respect to such payments, the Exchange Rate Agent is able to convert such
payments as provided below and the Specified Currency is not unavailable due to
the imposition of exchange controls or other circumstances beyond the control
of the Company, then (i) the payment of interest on this Security will be made
in the Specified Currency (or, if such Specified Currency is not at the time of
such payment legal tender for the payment of public and private debts, in such
other coin or currency of the country which issued such Specified Currency as
at the time of such payment is legal tender for the payment of such debts) by
check drawn upon a bank office located outside the United States and mailed to
the address of the Person entitled thereto as such address shall appear in the
Security Register, and (ii) payment of principal (and premium, if any) and
interest due at Maturity will be made in such Specified Currency (or, if
applicable, such other coin or currency) by wire transfer of immediately
available funds to an account maintained by the Holder hereof with a bank
office located in the country which issued the Specified Currency upon
presentation of this Security to the Paying Agent in time for such wire
transfer to be made by the Paying Agent in accordance with its normal
procedures.  Unless otherwise specified above, if this Security is denominated
in a Specified Currency, the Holder hereof may elect to receive payments of
principal of (and premium, if any) and interest on this Security in such
Specified Currency (a "Specified Currency Payment Election") by delivery of a
written request (including, in the case of an election with respect to payments
at Maturity, appropriate wire transfer instructions) to the Issuing and Paying
Agent at its principal corporate trust office referred to above on or prior to
the relevant Regular Record Date or the sixteenth day prior to Maturity, as the
case may be.  Such request shall be in writing (mailed or hand delivered) or by
facsimile transmission.  A Holder of a Security denominated in a Specified
Currency may elect to receive payment in the Specified Currency for all
principal (and premium, if any) and interest payments and need not file a
separate election for each payment.  Such election will remain in effect until
revoked by written notice to the Issuing and Paying Agent, but written notice
of any such revocation must be received by the Issuing and Paying Agent on or
prior to the relevant Regular Record Date or the sixteenth day prior to
Maturity, as the case may be.

       Reference is hereby made to the further provisions of this Security set
forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

                         (Form of Reverse of Security)

       This Security is one of a duly authorized issue of securities of the
Company (the "Securities") issued and to be issued in one or more series under
the Indenture, dated as of March 15, 1993 (the "Indenture"), between the
Company and PNC Bank, National Association, as Trustee (herein called the
"Trustee", which term includes any successor trustee under the Indenture), to
which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties
and immunities thereunder of the Company, the Trustee, the Holders of the
Securities and of the terms upon which the Securities are, and are to be,
authenticated and delivered.  This Security is one of the series designated on
the face hereof, limited to an aggregate principal amount not to exceed
$750,000,000 (or, if Securities of this series are to be Original Issue
Discount Securities or are to be denominated in one or more Specified
Currencies or with the amount payable in respect of principal of or any premium
or interest to be determined by reference to the value, rate or price of one or
more specified indices ("Indexed Securities"), such principal amount as shall
result in an aggregate initial offering price of Securities equivalent to no
more than $750,000,000), which amount may be increased at the option of the
Company if in the future it determines that it may wish to sell additional
Securities, which may be offered or sold either in the United States or outside
the United States or both simultaneously.  Except as otherwise may be stated on
the face hereof, the Securities of this series are issuable only as registered
Securities, without coupons, in denominations of $100,000 and integral
multiples of $1,000 in excess thereof (or in the case of Securities denominated
in a Specified Currency, in such minimum denomination not less than the
equivalent of $100,000 in such Specified Currency on the basis of the noon
buying rate for cable transfers in The City of New York as certified for
customs purposes by (or, if not so certified, as otherwise determined by) the
Federal Reserve Bank of New York (the "Market Exchange Rate") for such
Specified Currency on the date the Company agrees to issue such Security and
such greater denomination or denominations as shall be set forth on the face
thereof).  The Securities of this series may be issued from time to time in
various principal amounts and currencies or currency units, may mature at
different times, may bear interest at different rates, may be subject to
different redemption provisions, if any, and may otherwise vary.  As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal
amount of Securities of this series and of like tenor of a different authorized
denomination, as requested by the Holder surrendering the same.

       The Securities are general, direct, unconditional and unsecured
obligations of the Company.

       Accrued interest hereon shall be calculated by multiplying the principal
amount specified on the face hereof by an accrued interest factor.  Such
accrued interest factor shall be computed by adding the interest factor
calculated for each day in the period for which accrued interest is being
calculated.  The interest factor (expressed as a decimal rounded upwards, if
necessary, as described below) for each such day shall be computed by dividing
the interest rate (expressed as a decimal rounded upwards, if necessary, as
described below) applicable to such day by 360, if the Interest Rate Basis
specified on the face hereof is the Commercial Paper Rate, Prime Rate, CD Rate,
Federal Funds Rate or LIBOR, by the actual number of days in the year (365 or
366, as the case may be) if the Interest Rate Basis specified on the face
hereof is the Treasury Rate, or by the number of days in the Computation Period
specified on the face hereof.  Except as otherwise provided herein, all
percentages resulting from any calculation with respect to this Security will
be rounded, if necessary, to the nearest one-hundred thousandth of a percentage
point, with five one-millionths of a percentage point rounded upwards (e.g.,
9.876545% (or .09876545) being rounded to 9.87655% (or .0987655) and 9.876544%
(or .09876544) being rounded to 9.87654% (or .0987654)), and all dollar amounts
and all amounts in Specified Currencies used in or resulting from such
calculations will be rounded to the nearest cent, or, if this Security is
denominated in a Specified Currency, the nearest unit (with one-half cent and
one-half unit being rounded upwards).

       The rate of interest on this Security will be reset daily, weekly,
monthly, quarterly, semi-annually or annually, as specified on the face hereof
under Interest Reset Period (each date upon which interest is so reset as
provided below being hereinafter referred to as an "Interest Reset Date"), and
the interest rate in effect on any day shall be (a) if such day is an Interest
Reset Date, the interest rate for such Interest Reset Date or (b) if such day
is not an Interest Reset Date the interest rate for the immediately preceding
Interest Reset Date; provided, however, that the interest rate in effect from
the Date of Issue of this Security (or one or more Predecessor Securities) to
but excluding the first Interest Reset Date will be the Initial Interest Rate.
Notwithstanding the foregoing, the interest rate hereon shall not be greater
than the Maximum Interest Rate, if any, or less than the Minimum Interest Rate,
if any, specified on the face hereof and in no event shall be higher than the
maximum rate permitted by New York law, as the same may be modified by United
States law of general application.  Unless otherwise specified on the face
hereof and except as provided in the next succeeding sentence, the Interest
Reset Date with respect to this Security will be, if the Interest Reset Period
specified on the face hereof is daily, each Market Day (as defined below); if
the Interest Reset Period specified on the face hereof is weekly (unless the
Interest Rate Basis specified on the face hereof is the Treasury Rate), the

"Interest Reset Month(s)" on the face hereof; and if the Interest Reset Period
specified on the face hereof is annually, the third Wednesday of the month in
each year specified under "Interest Reset Month(s)" on the face hereof.  If,
pursuant to the preceding sentence, any Interest Reset Date would otherwise be
a day that is not a Market Day with respect to this Security, the Interest
Reset Date shall be the next succeeding day that is a Market Day with respect
to this Security, except that if the Interest Rate Basis specified on the face
hereof is LIBOR and the next succeeding Market Day falls in the next succeeding
calendar month, such Interest Reset Date shall be the immediately preceding
Market Day.  Subject to applicable provisions of law and except as specified
herein, on each Interest Reset Date the rate of interest on this Security shall
be the rate determined in accordance with the provisions of the applicable
heading below.

       "Market Day" means (a) with respect to any Security (unless otherwise
provided in this definition), any Business Day, (b) with respect to Securities
that bear interest on the basis of the London Interbank Offered Rate as
determined from time to time, any Business Day that is also a London Banking

ECU Banking Association in Paris or otherwise generally regarded in the ECU
interbank market as a day in which payments in ECUs are made.

       Determination of Commercial Paper Rate.  If the Interest Rate Basis
specified on the face hereof is the Commercial Paper Rate, the interest rate
with respect to this Security for any Interest Reset Date shall equal (a) the
Money Market Yield (calculated as described below) of the rate on the second
Market Day with respect to this Security immediately preceding such Interest
Reset Date (the "Commercial Paper Interest Determination Date") for commercial
paper having the Index Maturity specified on the face hereof, (i) as published
in "Statistical Release H.15(519), Selected Interest Rates", or any successor
publication published by the Board of Governors of the Federal Reserve System
("H.15(519)"), under the heading "Commercial Paper", or (ii) if such rate is
not so published





                                      -7-
   19
prior to 3:00 P.M., New York City time, on the Calculation Date pertaining to
such Commercial Paper Interest Determination Date, then as published in
"Composite 3:30 P.M. Quotations for U.S. Government Securities", or any
successor publication published by the Federal Reserve Bank of New York
("Composite Quotations"), under the heading "Commercial Paper", or (b) if such
rate is not published in either H.15(519) or Composite Quotations by 3:00 P.M.,
New York City time, on such Calculation Date, the Money Market Yield of the
arithmetic mean, as calculated by the Calculation Agent on such Calculation
Date, of the offered rates, as of 11:00 A.M., New York City time, on such
Commercial Paper Interest Determination Date, of three leading dealers of
commercial paper in The City of New York selected by the Calculation Agent for
commercial paper having the Index Maturity specified on the face hereof placed
for an industrial issuer whose bond rating is "AA", or the equivalent, from a
nationally recognized rating agency, in each of the above cases adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication by the Spread Multiplier, if any, specified on the face
hereof; provided, however, that if at least two of the dealers selected as
aforesaid by the Calculation Agent are not quoting as mentioned in this
sentence, the Commercial Paper Rate shall be the Commercial Paper Rate in
effect on such Commercial Paper Interest Determination Date.

       "Money Market Yield" shall be a yield (expressed as a percentage rounded
upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point), calculated in accordance with the following formula:

                                                   D x 360   
                     Money Market Yield =        ------------  x 100
                                                 360 - (D x M)

where "D" refers to the per annum rate for commercial paper quoted on a bank
discount basis and expressed as a decimal; and "M" refers to the actual number
of days in the interest period for which interest is being calculated.

       Determination of Prime Rate.  If the Interest Rate Basis specified on
the face hereof is the Prime Rate, the Interest Rate with respect to this
Security for any Interest Reset Date shall equal (a) the rate on the second
Business Day with respect to this Security immediately preceding such Interest
Reset Date (the "Prime Rate Interest Determination Date") as published in
H.15(519) under the heading "Bank Prime Loan"; (b) if such rate is not so
published prior to 9:00 A.M., New York City time, on the Calculation Date
pertaining to such Prime Rate Interest Determination Date, the arithmetic mean,
as calculated by the Calculation Agent on such Calculation Date, of the rates
of interest publicly announced by each bank that appears on the Reuters Screen
NYMF Page as such bank's prime rate or base lending rate as in effect for that
Prime Rate Interest Determination Date, (c) if fewer than four such rates but
more than one such rate appear on the Reuters Screen NYMF Page for that Prime
Rate Interest Determination Date, the Prime Rate will be the arithmetic mean,
as calculated by the Calculation Agent, of the prime rates quoted on the basis
of the actual number of days in the year divided by a 360-day year as of the
close of business on such Prime Rate Interest Determination Date by four major
money center banks in The City of New York selected by the Calculation Agent,
and (d) if fewer than two quotations are provided, the Prime Rate shall be
determined on the basis of the rates furnished in The City of New York by the
appropriate number of substitute banks or trust companies organized and doing

total equity capital of at least $500 million and being subject to supervision
or examination by Federal or State authority, selected by the Calculation Agent
to provide such rate or rates in each of the above cases adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication of the Spread Multiplier, if any, specified on the face
hereof; provided, however, that if the banks selected as aforesaid are not
quoting as mentioned in this sentence, the Prime Rate will be the Prime Rate in
effect on such Prime Rate Interest Determination Date.

face hereof is the CD Rate, the Interest Rate with respect to any Interest
Reset Date shall equal (a) the rate on the second Business Day with respect to
this Security immediately preceding such Interest Reset Date (the "CD Rate
Interest Determination Date") for negotiable certificates of deposit having the
Index Maturity specified on the face hereof, (i) as published in H.15(519)
under the heading "CDs (Secondary Market)", or (ii) such rate is not published
prior to 3:00 P.M., New York City time, on the Calculation Date pertaining to
such CD Rate Interest Determination Date, then as published in Composite
Quotations under the heading "Certificates of Deposit", or (b) if such rate is
not yet published in either H.15(519) or Composite Quotations by 3:00 P.M., New
York City time, on such Calculation Date the arithmetic mean, as calculated by
the Calculation Agent, of the secondary market offered rates, as of 10:00 A.M.,
New York City time, on such CD Rate Interest Determination Date, of three
leading nonbank dealers of negotiable U.S. dollar certificates of deposit in
The City of New York selected by the Calculation Agent for negotiable
certificates of deposit of major United States money market banks with a
remaining maturity closest to the Index Maturity specified on the face hereof
in a denomination of $5,000,000 in each of the above cases adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication of the Spread Multiplier, if any, specified on the face
hereof; provided, however, that if the dealers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the CD Rate
will be the CD Rate in effect on such CD Rate Interest Determination Date.

       Determination of Federal Funds Rate.  If the Interest Rate Basis

rate is not yet published in either H.15(519) or Composite Quotations, the
arithmetic mean, as calculated by the Calculation Agent on such Calculation
Date, of the rates, as of 11:00 A.M., New York City time, on such Federal Funds
Interest Determination Date, for the last transaction in overnight Federal
Funds arranged by three leading brokers of Federal Funds transactions in The
City of New York selected by the Calculation Agent, in each of the above cases
adjusted by the addition or subtraction of the Spread, if any, specified on the
face hereof, or by multiplication by the Spread Multiplier, if any, specified
on the face hereof; provided, however, that if the brokers selected as
aforesaid by the Calculation Agent are not quoting as mentioned in this
sentence, the Federal Funds Rate will be the Federal Funds Rate in effect on
such Federal Funds Interest Determination Date.

       Determination of LIBOR.  If the Interest Rate Basis specified on the
face hereof is LIBOR, the interest rate with respect to this Security for any
Interest Reset Date shall be determined by the Calculation Agent in accordance
with the following provisions:

                     (i)  On each Interest Determination Date shown on the face
              hereof, LIBOR will be, as shown on the face hereof, (a) the
              arithmetic mean of the offered rates for deposits in U.S. dollars
              having the Index Maturity shown on the face hereof, commencing on
              the second London Banking Day (as defined below) immediately
              following such Interest Determination Date, that appear on the
              Reuters Screen LIBO Page as of 11:00 A.M., London time, on such
              Interest Determination Date, if at least two such offered rates
              appear on the Reuters Screen LIBO Page ("LIBOR Reuters"), or (b)
              the rate for deposits in U.S. dollars having the Index Maturity
              shown on the face hereof, commencing on the second London Banking
              Day immediately following such Interest Determination Date, that





                                      -9-
   21
              appears on the Telerate Page 3750 as of 11:00 A.M., London time,
              on such Interest Determination Date ("LIBOR Telerate").  "Reuters
              Screen LIBO Page" means the display designated as page "LIBO" on
              the Reuters Monitor Money Rates Service (or such other page as
              may replace the LIBO page on that service for the purpose of
              displaying London interbank offered rates of major banks). 
              "Telerate Page 3750" means the display designated as page "3750"
              on the Telerate Service (or such other page as may replace page
              "3750" on that service or such other service or services as may
              be nominated by the British Bankers' Association for the purpose
              of displaying London interbank offered rates for U.S. dollar
              deposits).  If neither LIBOR Reuters nor LIBOR Telerate is shown
              on the face hereof, LIBOR will be determined as if LIBOR Reuters
              had been so designated.  If two or more offered rates appear on
              the Reuters Screen LIBO Page, the rate in respect of such LIBOR
              Interest Determination Date will be the arithmetic mean (rounded,
              if necessary, to the nearest one hundred-thousandth of a percent) 
              of such offered rates as determined by the Calculation Agent.  If
              fewer than two offered rates appear on the Reuters Screen LIBO
              Page, or if no rate appears on the Telerate Page 3750, as 
              applicable, LIBOR in respect of that Interest Determination Date 
              will be determined as if the parties had specified the rate 
              described in (ii) below. 
        
                     (ii) On any Interest Determination Date on which fewer
              than two offered rates appear on the Reuters Screen LIBO Page, as
              specified in (i)(a) above, or on which no rate appears on
              Telerate Page 3750, as specified in (i)(b) above, as applicable,
              LIBOR will be determined on the basis of the rates at which
              deposits in U.S. dollars having the Index Maturity shown on the
              face hereof are offered at approximately 11:00 A.M., London time,
              on such Interest Determination Date by four major banks in the
              London interbank market selected, after consultation with the
              Company, by the Calculation Agent (the "Reference Banks") to
              prime banks in the London interbank market commencing on the
              second London Banking Day immediately following such Interest
              Determination Date and in a principal amount equal to an amount
              of not less than $1,000,000 that is representative for a single
              transaction in such market at such time.  The Calculation Agent
              will request the principal London office of each of such
              Reference Banks to provide a quotation of its rate.  If at least
              two such quotations are provided, LIBOR in respect of such
              Interest Determination Date will be the arithmetic mean of all
              such quotations.  If fewer than two quotations are provided,
              LIBOR in respect of such Interest Determination Date will be the
              arithmetic mean of the rates quoted at approximately 11:00 A.M.,
              New York City time, on such Interest Determination Date by three
              major banks in The City of New York selected, after consultation
              with the Company, by the Calculation Agent for loans in U.S.
              dollars to leading European banks having the Index Maturity shown
              on the face hereof commencing on the second London Banking Day
              immediately following such Interest Determination Date and in a
              principal amount equal to an amount of not less than $1,000,000
              that is representative for a single transaction in such market at
              such time; provided, however, that if the banks in The City of
              New York selected as aforesaid by the Calculation Agent are not
              quoting as mentioned in this sentence, LIBOR with respect to such
              Interest Determination Date will be LIBOR in effect on such
              Interest Determination Date.

              LIBOR determined with respect to any Interest Determination Date
will become effective on and as of the second London Banking Day following such
Interest Determination Date (the "LIBOR Reset Date"); provided, however, that
(i) the interest rate in effect for the period from the Original Date of Issue
to the first LIBOR Reset Date will be the Initial Interest Rate shown on the
face hereof and (ii) the interest rate in effect for the ten calendar days
immediately preceding the Maturity Date will be that in effect on the tenth
calendar day preceding such Maturity Date.  The interest rate for each such
LIBOR Reset Date shall be LIBOR applicable to such LIBOR Reset Date plus or
minus the Spread





                                      -10-
   22
and/or multiplied by the Spread Multiplier, as shown on the face hereof.
"London Banking Day" means any day on which dealings in deposits in U.S.
dollars are transacted in the London interbank market.

       Determination of Treasury Rate.  If the Interest Rate Basis specified on
the face hereof is the Treasury Rate, the interest rate with respect to this
Security for any Interest Reset Date shall equal (a) the rate for the most
recent auction of direct obligations of the United States ("Treasury bills")
having the Index Maturity specified on the face hereof as published in
H.15(519) under the heading "U.S. Government Securities/Treasury Bills -
auction average (investment)" on the Treasury Interest Determination Date (as
defined below) or (b) if such rate is not so published by 9:00 A.M., New York
City time, on the Calculation Date pertaining to such Treasury Interest
Determination Date, the auction average rate (expressed as bond equivalent on
the basis of a year of 365 or 366 days, as applicable, and applied on a daily
basis) for such auction as otherwise announced by the United States Department
of the Treasury or (c) in the event that the results of the auction of Treasury
bills having the Index Maturity specified on the face hereof are not published
or reported as provided in (a) or (b) above by 3:00 P.M., New York City time,
on such Calculation Date or if no such auction is held in a particular week,
the yield to maturity (expressed as a bond equivalent on the basis of a year of
365 or 366 days, as applicable, and applied on a daily basis) of the arithmetic
mean, as calculated by the Calculation Agent on such Calculation Date, of the
secondary market bid rates as of approximately 3:30 P.M., New York City time,
on such Treasury Interest Determination Date, of three leading primary United
States government securities dealers selected by the Calculation Agent for the
issue of Treasury bills with a remaining maturity closest to the Index Maturity
specified on the face hereof, in each of the above cases adjusted by the
addition or subtraction of the Spread, if any, specified on the face hereof, or
by multiplication by the Spread Multiplier, if any, specified on the face
hereof; provided, however, that if at least two of the dealers selected as
aforesaid by the Calculation Agent are not quoting as mentioned in this
sentence, the Treasury Rate shall be the Treasury Rate on such Treasury
Interest Determination Date.

       The "Treasury Interest Determination Date" pertaining to an Interest
Reset Date will be the day on which Treasury bills are auctioned for the week
in which such Interest Reset Date falls, or if no auction is held for such
week, the Monday of such week (or if Monday is a legal holiday, the next
succeeding Market Day) and the Interest Reset Date will be the Market Day
immediately following such Treasury Interest Determination Date.  Treasury
bills are usually sold at auction on Monday of each week, unless that day is a
legal holiday, in which case the auction is usually held on the following
Tuesday, except that such auction may be held on the preceding Friday.  If an
auction is held for such week on Monday or the preceding Friday, such Monday or
preceding Friday shall be the Treasury Interest Determination Date for such
week, and the Interest Reset Date for such week shall be the Tuesday of such
week (or, if such Tuesday is not a Market Day, the next succeeding Market Day).
If the auction for such week is held on any day of such week other than Monday,
then such date shall be the Treasury Interest Determination Date and the
Interest Reset Date for such week shall be the next succeeding Market Day.

       Unless otherwise specified on the face hereof, the Calculation Date
pertaining (a) to any Commercial Paper Rate Interest Determination Date, CD
Rate Interest Determination Date, Treasury Interest Determination Date or
Federal Funds Rate Interest Determination Date, as the case may be, shall be
the earlier of the (i) tenth day after such interest determination date or, if
any such day is not a Market Day with respect to this Security, the next
succeeding Market Day and (ii) the Market Day next preceding such Interest
Payment Date or date of Maturity, as the case may be and (b) to any Prime Rate
Interest Determination Date or LIBOR Interest Determination Date shall be such
Prime Rate Interest Determination Date or such LIBOR Interest Determination
Date, as the case may be.  The Calculation Agent shall calculate the interest
rate hereon in accordance with the foregoing on or before each Calculation
Date.  At the request of the Holder hereof, the Calculation Agent will provide
to the Holder hereof the interest rate hereon then in effect and, if
determined, the interest rate which will





                                     -11-
   23
become effective as of the next Interest Reset Date.  Unless otherwise
specified on the face hereof, the Calculation Agent shall be the Trustee.

       If this Security is designated on the face hereof as an Original Issue
Discount Security, then, notwithstanding anything to the contrary contained in
this Security, upon the redemption or acceleration of Maturity of this Security
there shall be payable, in lieu of the principal amount due at the Stated
Maturity hereof, as specified on the face hereof, an amount equal to the
Amortized Face Amount of this Security.  The "Amortized Face Amount" shall be
the amount equal to (a) the issue price of this Security (as defined below),
plus (b) that portion of the difference between the issue price and the
principal amount of this Security that has been amortized at the Stated Yield
(as defined below) of this Security (computed in accordance with generally
accepted United States bond yield computation principles) at the date as of
which the Amortized Face Amount is calculated, but in no event shall the
Amortized Face Amount exceed the principal amount of this Security due at the
Stated Maturity hereof.  As used in the previous sentence "issue price" means
the principal amount due at the Stated Maturity hereof less the Total Amount of
OID specified on the face hereof and the "Stated Yield" means the Yield to
Maturity specified on the face hereof (or if not so specified, the yield to
maturity compounded semi-annually and computed in accordance with generally
accepted United States bond yield computation principles) for the period from
the Date of Issue to the Stated Maturity on the basis of the issue price and
such principal amount.

       If this Security is denominated in a Specified Currency, unless the
Holder hereof is entitled to make, and has made, a Specified Currency Payment
Election with respect to such payments as provided on the face hereof, the
Holder of this Security shall receive payments of principal (and premium, if
any) and interest in U.S. dollars at an exchange rate based on the highest bid
quotation in The City of New York received by the Exchange Rate Agent (who,
unless otherwise specified on the face hereof, shall be the Issuing and Paying
Agent) at approximately 11:00 A.M., New York City time, on the second Market
Day with respect to this Security preceding the applicable payment date from
three recognized foreign exchange dealers (one of which may be the Exchange
Rate Agent) selected by the Exchange Rate Agent and approved by the Company for
the purchase by the quoting dealer of the Specified Currency for U.S. dollars
for settlement on such payment date in the aggregate amount of such Specified
Currency payable to all Holders of Securities of this series denominated in
such Specified Currency and scheduled to receive U.S. dollar payment on such
payment date and at which the applicable dealer commits to execute a contract.
All currency exchange costs incurred by the Company in converting a Specified
Currency into U.S. dollars in order to make payments hereon will be borne by
the Holder of this Security by deductions from such payments.  If such bid
quotations are not available, or if a Specified Currency Payment Election has
been made with respect to such payments, payments will be made in the Specified
Currency (or, if such Specified Currency is not at the time of such payment
legal tender for the payment of public and private debts, such other coin or
currency of the country which issued such Specified Currency as at the time of
such payment is legal tender for the payment of such debts); provided, however,
that if such Specified Currency (or, if applicable, such other coin or
currency) is unavailable due to the imposition of exchange controls or other
circumstances beyond the Company's control, the Company will be entitled to
make payments in U.S. dollars on the basis of the Market Exchange Rate for such
specified currency (or, if applicable, such other coin or currency) on the
second Market Day prior to such payment or, if such Market Exchange Rate is not
then available, on the basis of the most recently available Market Exchange
Rate or as otherwise indicated hereon.

       If one or more Redemption Dates (or ranges of Redemption Dates) is
specified on the face hereof, this Security is subject to redemption upon not
less than 30 days' notice by mail, on any such date (or during any such range)
as a whole, or from time to time in part, at the option of the Company, at a
Redemption Price determined as provided in the next succeeding sentence,
together with accrued interest to the Redemption Date; but interest instalments
whose Stated Maturity on or prior to the





                                     -12-
   24
Redemption Date will be payable to the Holder hereof (or one or more
Predecessor Securities) of record at the close of business on the Regular
Record Dates referred to on the face hereof, all as provided in the Indenture.
If applicable, the "Redemption Price" for any such redemption shall be the
amount determined by multiplying the Redemption Percentage specified on the
face hereof with respect to the relevant Redemption Date (or range of such
dates) by the portion of the principal amount hereof (or, if this Security is
an Original Issue Discount Security, the portion of the Amortized Face Amount
hereof) to be redeemed; provided, however, that in no event shall the
Redemption Price be less than 100% of the portion of the principal amount
hereof (or, if this Security is an Original Issue Discount Security, the
portion of the Amortized Face Amount hereof) to be redeemed.

       Notice of redemption having been given as aforesaid, this Security (or
the portion of the principal amount hereof so to be redeemed) shall, on the
Redemption Date, become due and payable at the Redemption Price herein
specified, and from and after such date (unless the Company shall default in
the payment of the Redemption Price and accrued interest) shall cease to bear
interest.  In the case of any partial redemption at the election of the Company
of Securities of this series, the Securities of a particular tenor to be
redeemed shall be selected by the Trustee not more than 45 days prior to the
Redemption Date by such method as the Trustee shall deem fair and appropriate
and which may provide for the selection for redemption of portions of the
principal amount of Securities.  In the event of any redemption of this
Security in part only, a new Security or Securities of this series of like
tenor for the unredeemed portion hereof will be issued in the name of the
Holder hereof upon the cancellation hereof, provided that such unredeemed
portion shall not be less than the minimum denomination of this Security.

       If one or more Redemption Dates (Option of Holder) (or ranges of such
dates) is specified on the face hereof, this Security is subject to redemption
on any such date (or during any such range) or, if such date is not a Market
Day, on the first Market Day following such date, as a whole or from time to
time in part, at the election of the Holder hereof at a Redemption Price
determined as provided in the fifth succeeding sentence together with accrued
interest thereon to the Redemption Date, but interest instalments whose Stated
Maturity is on or prior to the Redemption Date will be payable to the Holder
hereof of record at the close of business on the Regular Record Date referred
to on the face hereof, all as provided in the Indenture.  Such election shall
be effected by the Holder hereof delivering to the Company at the principal
corporate trust office of the Issuing and Paying Agent in the Borough of
Manhattan, The City of New York, or such other office or agency of the Company
maintained by it for that purpose in the Borough of Manhattan, The City of New
York, not less than 30 nor more than 60 days prior to the date on which this
Security is to be redeemed, or during such other Notice Period specified on the
face hereof, a notice requesting such redemption in the form described below
and specifying the date upon which this Security is to be redeemed.  Any notice
given by a Holder pursuant to this paragraph shall consist of either (i) this
Security with the form entitled "Option to Elect Redemption" set forth of the
end of this Security duly completed or (ii) a telegram, facsimile transmission
or a letter from a member of a national securities exchange, or the National
Association of Securities Dealers, Inc. or a commercial bank or trust company
in the United States setting forth the name of the Holder hereof, the principal
amount of this Security, the principal amount of this Security to be redeemed,
the certificate number or a description of the terms of this Security, a
statement that the option to elect redemption is being exercised thereby and a
guarantee that this Security, together with the duly completed form entitled
"Option to Elect Redemption" below, will be received by the Issuing and Paying
Agent not later than the fifth Market Day after the date of such telegram,
facsimile transmission or letter; provided, however, that such telegram,
facsimile transmission or letter shall only be effective if this Security and
form duly completed are received by the Issuing and Paying Agent by such fifth
Market Day.  Exercise of the redemption option by the Holder hereof will be
irrevocable.  If applicable, the "Redemption Price" for any such redemption
shall be the amount determined by multiplying the Redemption Percentage (Option
of Holder), specified on the face hereof with respect to the relevant
Redemption Date (Option of Holder) (or range of such dates) by the portion of
the





                                      -13-
   25
principal amount hereof (or, if this Security is an Original Issue Discount
Security, the portion of the Amortized Face Amount hereof) to be redeemed,
together with the interest accrued thereon to the Redemption Date; provided,
however, that in no event shall the Redemption Price be less than 100% of the
portion of the principal amount hereof (or, if this Security is an Original
Issue Discount Security, the portion of the Amortized Face Amount hereof) to be
redeemed.

       The Indenture contains provisions for defeasance and covenant defeasance
at any time of the entire indebtedness on this Security upon compliance by the
Company with certain conditions set forth therein.

       If an Event of Default with respect to the Securities of this series
shall occur and be continuing, the principal of the Securities of this series
(or, in the case of Original Issue Discount Securities, the Amortized Face
Amount thereof) may be declared due and payable in the manner and with the
effect provided in the Indenture.  Upon payment (i) of the amount of principal
so declared due and payable and (ii) of interest on any overdue principal and
overdue interest (in each case to the extent that the payment of such interest
shall be legally enforceable), all of the Company's obligations in respect of
the payment of the principal of the interest, if any, on the Securities of this
series shall terminate.

       The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with
the consent of the Holders of 66 2/3% in principal amount of the Securities at
the time outstanding of each series to be affected.  The Indenture also
contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time outstanding, on
behalf of the Holders of all Securities of such series, to waive compliance by
the Company with certain provisions of the Indenture and certain past defaults
under the Indenture and their consequences.  Any such consent or waiver by the
Holder of this Security shall be conclusive and binding upon such Holder and
upon all future Holders of this Security and of any Security issued upon the
registration of transfer hereof or in exchange herefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Security.

       No reference herein to the Indenture and no provision of this Security
or of the Indenture shall alter or impair the obligation of the Company, which
is absolute and unconditional, to pay the principal of (and premium, if any)
and interest on this Security at the times, place and rate, and in the coin or
currency, herein prescribed.

       As provided in the Indenture and subject to certain limitations therein
set forth, the transfer of this Security is registrable in the Debt Security
register, upon surrender of this Security for registration of transfer at the
office or agency of the Company in any place where the principal of (and
premium, if any) and interest on this Security are payable, duly endorsed by,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Debt Security registrar duly executed by, the Holder hereof or
his attorney duly authorized in writing, and thereupon one or more new
Securities of this series and of like tenor, of authorized denominations and
for the same aggregate principal amount, will be issued to the designated
transferee or transferees.

       As provided in the Indenture and subject to certain limitations therein
set forth, the Securities of this series are exchangeable for a like aggregate
principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same.  In
the event of any redemption at the election of the Company, the Trustee shall
not be required to exchange or register a transfer of (a) any Securities of
this series of like tenor for a period of fifteen days next preceding the
mailing of any notice of redemption, or (b) any Security selected, called or
being called for redemption except, in the case of any Security to be redeemed
in part, the portion





                                      -14-
   26
thereof not to be so redeemed.  Following the exercise of any redemption option
by the Holder hereof, the Trustee shall not be required to issue, register the
transfer of or exchange that portion of this Security with respect to which
such option has been exercised.

       No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

       The Securities of this series may be issued in the form of one or more
Global Securities to The Depository Trust Company as depositary for the Global
Securities of this series (the "Depositary") or its nominee and registered in
the name of the Depositary or such nominee.  If the face of this Security
contains a legend indicating that this Security is a Global Security so
registered, the transfer and exchange hereof is subject to the additional
limitations set forth in such legend.

       Prior to due presentment of this Security for registration of transfer,
the Company, the Trustee and any agent of the Company or the Trustee may treat
the Person in whose name this Security is registered as the owner hereof for
all purposes, whether or not this Security be overdue, and neither the Company,
the Trustee nor any such agent shall be affected by notice to the contrary.

       All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
