          ASHLAND INC., a corporation duly organized and existing under the laws

           , or registered assigns, the principal sum of

          U.S. DOLLARS on the Maturity Date specified above, and to pay interest
thereon at a rate per annum equal to the Initial Interest Rate specified above
until the first Interest Reset Date specified above following the Original Issue
Date specified above 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 LIBOR",
"Determination of Treasury Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate", depending upon whether the Interest Rate Basis
specified above is the Commercial Paper Rate, Prime Rate, LIBOR, Treasury Rate,
Federal Funds Rate or CD Rate, which rate may be adjusted by adding or
subtracting the Spread or multiplying by the Spread Multiplier (as such terms
are defined below) depending on whether a Spread or Spread Multiplier is
designated above, until the principal hereof is paid or duly made available for
payment.  In addition, a Floating Rate note may bear interest at the lowest or
highest or average of two or more interest rate formulae.  The "Spread", if any,
is the number of basis points designated above, and the "Spread Multiplier", if
any, is the percentage designated above.  The Company will pay interest monthly,
quarterly, semi-annually or annually as specified above under "Interest Payment
Period", commencing with the first Interest Payment Date specified above next
succeeding the Original Issue Date and thereafter on the Interest Payment Dates
as specified above, and on the Maturity Date.  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 Regular Record Date for such interest set forth above (whether or not a
Business Day), next preceding such Interest Payment Date; PROVIDED, HOWEVER,
that interest payable at Maturity shall be payable to the Person to whom
principal shall be payable.  Except as otherwise provided in the Indenture, any
such interest not so punctually paid or duly provided for will forthwith cease
to be payable to the Holder on such Regular Record Date and 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
thereof shall be given to Holders of Securities of this series not less than 10
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 the Securities of this series

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, premium, if
any, and interest on this Security will be made to the Depositary, or its
nominee, as Holder thereof, in accordance with arrangements then in effect
between the Trustee and the Depositary, 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 at the option of the Company
payment of interest (except at maturity) may be made by United States dollar
check mailed to the address of the Person entitled thereto as such address shall
appear in the Security Register (which, in the case of Book-Entry Notes, will be
a nominee of the Depositary).  Payment of the principal, premium, if any, and
interest on this Security due at Maturity will be made in immediately available
funds upon surrender of this Security to the Paying Agent; PROVIDED that this
Security is presented to the Paying Agent in time for the Paying Agent to make
such payment in accordance with its normal procedures.  "Maturity" shall mean
the date on which the principal of this Security or an installment of principal
becomes due, whether on the Maturity Date specified above, upon redemption or
otherwise.

          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 IN FULL AT THIS PLACE.

          Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof, directly or through an
Authenticating Agent, by manual signature of an authorized officer, 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 under its corporate seal.

                              MEDIUM-TERM, SERIES G

                                 (Floating Rate)

          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 an Indenture, dated as of August 15, 1989, as amended and restated
as of August 15, 1990 (herein called the "Indenture"), between the Company and
Citibank, N.A., 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.

          This Security may not be redeemed prior to the Redemption Date set
forth on the face hereof.  If no Redemption Date is so set forth, this Security
is not redeemable prior to the Maturity Date.  On or after the Redemption Date
set forth on the face hereof, this Security is redeemable in whole or in part in
increments of U.S. $1,000 at the option of the Company at a redemption price
equal to 100% of the principal amount to be redeemed together with interest
thereon to the date of redemption.

          Notice of redemption will be given by mail to Holders of Securities,
not more than 60 nor less than 30 days prior to the date fixed for redemption,
all as provided in the Indenture.

          In the event of redemption of this Security in part only, a new
Security or Securities of this series and of like tenor for the unredeemed
portion hereof will be issued in the name of the Holder hereof upon the
surrender hereof.

                                                                               7

          The Securities of this series will not have a sinking fund unless
otherwise specified in the applicable pricing supplement.

          Commencing with the first Interest Reset Date specified on the face
hereof following the Original Issue Date, the rate at which interest on this
Security is payable shall be adjusted daily, weekly, monthly, quarterly,
semi-annually or annually as shown on the face hereof under "Interest Rate Reset
Period"; PROVIDED, HOWEVER, that the interest rate in effect hereon for the 10
days immediately prior to the Maturity hereof, shall be that in effect on the
10th day preceding the Maturity hereof.  Each such adjusted rate shall be
applicable on and after the Interest Reset Date to which it relates, to but not
including the next succeeding Interest Reset Date or until Maturity, as the case
may be.  If any Interest Reset Date specified on the face hereof would otherwise
be a day that is not a Business Day, such Interest Reset Date shall be postponed
to the next succeeding day that is a Business Day, except that if (i) the rate
of interest on the Security shall be determined in accordance with the
provisions of the heading "Determination of LIBOR" below, and (ii) such London
Banking Day is in the next succeeding calendar month, such Interest Reset Date
shall be the immediately preceding London Banking Day.  "Business Day" means any
day, other than a Saturday or Sunday, that meets each of the following
applicable requirements: the day is (a) not a day on which banking institutions
are authorized or required by law or regulation to be closed in The City of New
York, (b) if the Note is denominated in a Specified Currency other than the
European Currency Unit as defined and revised from time to time by the Council
of the European Communities ("ECU") or United States dollars, not a day on which
banking institutions are authorized or required by law or regulation to close in
the financial center of the country issuing the Specified Currency, (c) if the
Note is denominated in ECU, any day that is 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 on which payments in ECU are made, and (d) with
respect to LIBOR Notes, a London Banking Day. "London Banking Day" means any day
on which dealings in deposits in United States dollars are transacted in the
London interbank market.  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.

          The interest rate on this Security will in no event be higher than the
maximum rate permitted by New York law as

<PAGE>

                                                                               8

the same may be modified by United States law of general applicability.

          DETERMINATION OF COMMERCIAL PAPER RATE.  The interest rate payable
with respect to this Security shall be calculated by the Calculation Agent with
reference to the Commercial Paper Rate and the Spread or Spread Multiplier, if
any, specified on the face hereof.  "Commercial Paper Rate" means, with respect
to each Interest Determination Date specified on the face hereof, the Money
Market Yield (calculated as described below) of the rate on such date for
commercial paper having the Index Maturity specified on the face hereof as
published by the Board of Governors of the Federal Reserve System in
"Statistical Release H.15(519), Selected Interest Rates" or any successor
publication of the Board of Governors of the Federal Reserve System
("H.15(519)") under the heading "Commercial Paper".  In the event that such rate
is not published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
will be the Money Market Yield of the rate on such Interest Determination Date
for commercial paper having the Index Maturity specified on the face hereof as
published by the Federal Reserve Bank of New York in its daily statistical
release, "Composite 3:30 P.M. Quotations for U.S. Government Securities"
("Composite Quotations") under the heading "Commercial Paper".  If such rate is
not yet published by 3:00 P.M., New York City time, on the Calculation Date
pertaining to such Interest Determination Date, then the Commercial Paper Rate
for such Interest Determination Date will be calculated by the Calculation Agent
and will be the Money Market Yield of the arithmetic mean (rounded to the next
higher one-hundred thousandth of a percentage point) of the offered rates of
three leading dealers of commercial paper in The City of New York selected by
the Calculation Agent as of 11:00 A.M., New York City time, on such Interest
Determination Date 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; PROVIDED, HOWEVER,
that if the dealers selected as aforesaid by the Calculation Agent are not
quoting as mentioned in this sentence, the Commercial Paper Rate will be the
Commercial Paper Rate in effect on such Interest Determination Date.

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

<PAGE>

                                                                               9

                                   Money Market Yield =   D  x  360     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.  The interest rate payable with respect
to this Security shall be calculated by the Calculation Agent with reference to
the Prime Rate and the Spread or Spread Multiplier, if any, specified on the
face hereof.  "Prime Rate" means, with respect to each Interest Determination
Date specified on the face hereof, the arithmetic mean (rounded to the next
higher one-hundred thousandth of a percentage point) of the prime rates quoted
on the basis of the actual number of days in the year divided by 365 or 366
days, as the case may be, as of the close of business on such Interest
Determination Date by three major money center banks in The City of New York
selected by the Calculation Agent.  If fewer than three such quotations are
provided, the Prime Rate shall be determined on the basis of the rates furnished
in The City of New York by three substitute banks or trust companies organized
and doing business under the laws of the United States, or any state thereof,
having total equity capital of at least U.S. $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; 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 Interest Determination Date.

          DETERMINATION OF LIBOR.  The interest rate payable with respect to
this Security shall be calculated with reference to LIBOR and the Spread or
Spread Multiplier, if any, specified on the face hereof.  "LIBOR" will be
determined with respect to each Interest Determination Date specified on the
face hereof by the Calculation Agent in accordance with the following
provisions: On each LIBOR Interest Determination Date, LIBOR will be determined
on the basis of the offered rate for deposits in U.S. dollars having the Index
Maturity specified in the applicable Pricing Supplement, commencing on the
second London Banking Day immediately following such LIBOR Interest
Determination Date, which appears on the Telerate Page 3750 as of 11:00 A.M.,
London time, on that LIBOR Interest Determination Date.  If such rate does not
so appear on the Telerate page 3750, the rate in respect of such LIBOR Interest
Determination Date will be determined on the basis of the rates at which

<PAGE>

                                                                              10

deposits in U.S. dollars are offered by four major banks in the London interbank
market, selected by the Calculation Agent at approximately 11:00 A.M., London
time, on the LIBOR Interest Determination Date next preceding the relevant
Interest Reset Date, to prime banks in the London interbank market for a period
of the Index Maturity commencing on that Interest Reset Date and in a principal
amount equal to an amount not less than $1,000,000 that is representative for a
single transaction in such market at such time.  In such case, the Calculation
Agent will request the principal London office of each of the aforesaid major
banks to provide a quotation of such rate.  If at least two such quotations are
provided in respect of such LIBOR Interest Determination Date, the rate for that
Interest Reset Date will be the arithmetic mean of the quotations, and, if fewer
than two quotations are provided as requested in respect of such LIBOR Interest
Determination Date, the rate for that Interest Reset Date will be the arithmetic
mean of the rates quoted by three major banks in The City of New York, selected
by the Calculation Agent (which may include one or more of the Agents or their
affiliates), at approximately 11:00 A.M., New York City time, on that LIBOR
Interest Determination Date for loans in U.S. dollars to leading European banks
for a period of the Index Maturity commencing on that Interest Reset Date and in
a principal amount equal to an amount not less than $1,000,000 that is
representative for a single transaction in such market at such time; PROVIDED,
HOWEVER, if the aforesaid rate cannot be determined by the Calculation Agent,
LIBOR in respect to such LIBOR Interest Determination Date will be LIBOR then in
effect on such LIBOR Interest Determination Date.

          "Telerate Page 3750" means the display page so designated on the Dow
Jones Telerate Service (or such other page as may replace that page on that
service, or such other service as may be nominated as the information vendor,
for the purpose of displaying rates or prices relating to LIBOR).

          DETERMINATION OF TREASURY RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Treasury Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Treasury Rate" means, with respect to each
Interest Determination Date specified on the face hereof, 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)" or, if not so published by 3:00 P.M., New York City time, on the
Calculation Date pertaining to such Interest Determination Date, the Treasury

<PAGE>

                                                                              11

Rate will be the auction average rate, expressed as a Bond Equivalent Yield
(calculated as described below), for such auction as otherwise announced by the
United States Department of the Treasury.  If the results of the auction of
Treasury bills having the Index maturity specified on the face hereof are not
published or announced as provided 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, then
the Treasury Rate shall be calculated by the Calculation Agent and shall be a
yield to maturity, expressed as a Bond Equivalent Yield, of the arithmetic mean
of the secondary market bid rates as of approximately 3:30 P.M., New York City
time, on such 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 specified Index
Maturity; PROVIDED, HOWEVER, that if the dealers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the Treasury
Rate with respect to such Interest Determination Date will be the Treasury Rate
in effect on such Interest Determination Date.

          "Bond Equivalent Yield" shall be a yield (expressed as a percentage
rounded to the next higher one-hundred thousandth of a percentage point)
calculated in accordance with the following formula:

     Bond Equivalent Yield    D  x  N      x  100
                           -------------
                           360 - (D x M)

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

          DETERMINATION OF FEDERAL FUNDS RATE.  The interest rate payable with
respect to this Security shall be calculated by the Calculation Agent with
reference to the Federal Funds Rate and the Spread or Spread Multiplier, if any,
specified on the face hereof.  "Federal Funds Rate" means, with respect to each
Interest Determination Date specified on the face hereof, the rate on that day
for Federal Funds as published in H.15(519) under the heading "Federal Funds
(Effective)" or, if not so published by 3:00 P.M., New York City time, on the
Calculation Date pertaining to such Interest Determination Date, then the
Federal Funds Rate for such Interest Determination Date will be the rate on such
Interest Determination Date as published in Composite Quotations under the
heading "Federal Funds/ Effective Rate".

                                                                              12

If such rate is not yet published by 3:00 P.M., New York City time, on the
Calculation Date pertaining to such Interest Determination Date, then the
Federal Funds Rate for such Interest Determination Date will be calculated by
the Calculation Agent and will be the arithmetic mean (rounded to the nearest
one-hundred thousandth of a percentage point) of the rates prior to 9:00 A.M.,
New York City time, on such 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;
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 with
respect to such Interest Determination Date will be the Federal Funds Rate in
effect on such Interest Determination Date.

          DETERMINATION OF CD RATE.  The interest rate payable with respect to
this Security shall be calculated by the Calculation Agent with reference to the
CD Rate and the Spread or Spread Multiplier, if any, specified on the face
hereof.  "CD Rate" means, with respect to each Interest Determination Date, the
rate on such date for negotiable certificates of deposit having the Index
Maturity specified on the face hereof as published in H.15(519) under the
heading "CDs (Secondary Market)" or, if not so published by 3:00 P.M., New York
City time, on the Calculation Date pertaining to such Interest Determination
Date, the CD Rate will be the rate on such Interest Determination Date for
negotiable certificates of deposit of the Index Maturity specified on the face
hereof as published in Composite Quotations under the heading "Certificates of
Deposit".  If such rate is not published by 3:00 P.M., New York City time, on
such Calculation Date, then the CD Rate on such Interest Determination Date will
be calculated by the Calculation Agent and will be the arithmetic mean (each as
rounded to the nearest one-hundred thousandth of a percentage point)  of the
secondary market offered rates as of the opening of business, New York City
time, on such Interest Determination Date, of three leading nonbank dealers in
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 of the highest credit standing (in the market for
negotiable certificates of deposit) with a remaining maturity closest to the
Index Maturity specified on the face hereof in a denomination of U.S.
$5,000,000; PROVIDED, HOWEVER, that if the dealers selected as aforesaid by the
Calculation Agent are not quoting as mentioned in this sentence, the CD Rate
with respect to such Interest Determination Date will be the CD Rate in effect
on such Interest Determination Date.

                                                                              13

          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, shown on the face hereof.  The Calculation Agent shall
calculate the interest rate on this Security in accordance with the foregoing on
or before each Calculation Date and shall promptly thereafter notify the Company
and the Trustee of such interest rate.  Any such calculation by the Calculation
Agent shall be conclusive and binding on the Company, the Trustee and the Holder
of this Security, absent manifest error.

          The Calculation Agent will, upon the request of the Holder of this
Security, provide to such Holder the interest rate hereon then in effect and, if
determined, the interest rate which will become effective as of the next
Interest Reset Date.

          If any Interest Payment Date specified on the face hereof would
otherwise be a day that is not a Business Day, the Interest Payment Date shall
be postponed to the next day that is a Business Day, except that if (i) the rate
of interest on this Security shall be determined in accordance with the
provisions of the heading "Determination of LIBOR" above and (ii) such London
Banking Day is in the next succeeding calendar month, such Interest Payment Date
shall be the immediately preceding London Banking Day.

          The Interest Determination Date pertaining to an Interest Reset Date
if the rate of interest on the Security shall be determined in accordance with
the provisions of the headings "Determination of Commercial Paper Rate",
"Determination of Prime Rate", "Determination of Federal Funds Rate" or
"Determination of CD Rate" above will be the second Business Day preceding such
Interest Reset Date.  The Interest Determination Date pertaining to an Interest
Reset Date if the rate of interest on this Security shall be determined in
accordance with the provisions of the heading "Determination of LIBOR" above
will be the second London Banking Day preceding such Interest Reset Date.  The
Interest Determination Date pertaining to an Interest Reset Date if the rate of
interest on the Security shall be determined in accordance with the provisions
of the heading "Determination of Treasury Rate" above (the "Treasury Interest
Determination Date") will be the day of the week in which such Interest Reset
Date falls on which Treasury bills would normally be auctioned.  Treasury bills
are usually sold at auction on the 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

<PAGE>

                                                                              14

preceding Friday.  If, as a result of a legal holiday, an auction is so held on
the preceding Friday, such Friday will be the Treasury Interest Determination
Date pertaining to the Interest Reset Date occurring in the next succeeding
week.  If an auction date shall fall on any Interest Reset Date for a Treasury
Rate Note, then such Interest Reset Date shall instead be the first Business
Day immediately following such auction date.

          The Calculation Date, if applicable, pertaining to any Interest
Determination Date shall be the tenth calendar day after such Interest
Determination Date, or if any such day is not a Business Day, the next
succeeding Business Day.

          Interest payments for this Security will include interest accrued to
but excluding the Interest Payment Date; PROVIDED, HOWEVER, that if the interest
rate with respect to this Security is reset daily or weekly, interest payable on
any Interest Payment Date, other than interest payable on any date on which
principal hereof is payable, will include interest accrued from but excluding
the second preceding Regular Record Date, or from and including the date of
issue, if no interest has been paid with respect to such Note, to and including
the next preceding Regular Record Date.  Accrued interest hereon from and
including the Original Issue Date, or from but excluding the last date to which
interest hereon has been paid or duly provided for, as the case may be, will be
an amount calculated by multiplying the face amount hereof by an accrued
interest factor.  Such accrued interest factor will be computed by adding the
interest factor calculated for each day from and including the Original Issue
Date, or from the last date to which interest shall have been paid or duly
provided for, as the case may be, to and including the date for which accrued
interest is being calculated.  The interest factor (expressed as a decimal
rounded upwards, if necessary, to the next higher one-hundred thousandth of a
percentage point) for each such day will be computed by dividing the interest
rate (expressed as a decimal rounded upwards, if necessary, to the next higher
one-hundred thousandth of a percentage point) applicable to such day by 360, in
the case of the Commercial Paper Rate, LIBOR, the Federal Funds Rate or the CD
Rate, or by the actual number of days in the year, in the case of the Treasury
Rate or the Prime Rate.  The interest factor for Floating Rate Notes for which
two or more interest rate formulae are applicable will be calculated in the same
manner as if only the lowest, highest or average of, as the case may be, such
interest rate formulae applied.

          Subject to a number of important qualifications and exceptions set
forth in the Indenture, the Indenture provides

                                                                              15

that neither the Company nor any Subsidiary (as defined in the Indenture) will
(i) issue, assume or guarantee any notes, bonds, debentures or other similar
evidences of indebtedness for money borrowed secured by a mortgage, lien, pledge
or other encumbrance upon any real or personal property located in the
continental United States of America without effectively providing that the
Securities will be secured equally and ratably with (or, at the option of the
Company, prior to) such indebtedness so long as such indebtedness shall be so
secured or (ii) enter into any Sale and Lease-Back Transactions (as defined in
the Indenture).

          The Indenture also provides that the Company at its option (a) will be
Discharged (as such term is defined in the Indenture) from any and all
obligations in respect of the Securities (except for certain obligations to
register the transfer or exchange of Securities, replace stolen, lost or
mutilated Securities, maintain paying agencies and hold moneys for payment in
trust) or (b) need not comply with certain restrictive covenants of the
Indenture, if there is deposited with the Trustee, in the case of Securities
denominated in U.S. dollars, U.S. Government Obligations (as defined in the
Indenture) or, in the case of Securities denominated in a foreign currency,
Foreign Government Securities (as defined in the Indenture), which through the
payment of interest thereon and principal thereof in accordance with their terms
will provide money or a combination of money and U.S. Government Obligations or
Foreign Government Securities, as the case may be, in an amount sufficient to
pay in the currency, currencies or currency unit or units in which the
Securities are payable, all the principal, premium, if any, and interest on, the
Securities on the dates such payments are due in accordance with the terms of
the Securities.

          If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner and with the effect provided in the
Indenture.

          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

<PAGE>

                                                                              16

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 or transfer hereof or in exchange herefor or in lieu
hereof, whether or not notation of such consent or waiver is made upon this
Security.

          As set forth in, and subject to, the provisions of the Indenture, no
Holder of any Security of this series will have any right to institute any
proceeding with respect to the Indenture or for any remedy thereunder, unless
such Holder shall have previously given to the Trustee written notice of a
continuing Event of Default with respect to this series, the Holders of not less
than 25% in principal amount of the Outstanding Securities of this series shall
have made written request, and offered reasonable indemnity, to the Trustee to
institute such proceeding as trustee, the Trustee shall not have received from
the Holders of a majority in principal amount of the Outstanding Securities of
this series a direction inconsistent with such request and the Trustee shall
have failed to institute such proceeding within 60 days; PROVIDED, HOWEVER, that
such limitations do not apply to a suit instituted by the Holder hereof for the
enforcement of payment of the principal, premium, if any, or interest on this
Security on or after the respective due dates expressed herein.

          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, premium, if any, and interest
on this Security at the times, places 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 Security
Register, upon surrender of this Security for registration of transfer at the
corporate trust office of the Trustee or such other office or agency as may be
designated by the Company in the Borough of Manhattan, The City of New York,
duly endorsed by, or accompanied by a written instrument of transfer in form
satisfactory to the Company and the 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 with like terms

                                                                              17

and conditions and for the same aggregate principal amount will be issued to the
designated transferee or transferees.

          The Securities of this series are issuable only in registered form,
without coupons, in denominations of $1,000 and any integral multiple of $1,000
in excess thereof.  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 and with like terms and conditions, as
requested by the Holder surrendering the same.

          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.

          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 is overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the
contrary.

          The Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York.

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