    The specific terms of the Offered Securities in respect of which this
Prospectus is being delivered, such as, where applicable, (i) in the case of
Debt Securities, the specific designation, aggregate principal amount, currency,

by such persons acting as principal for their own accounts, at market prices

*Fixed charges exceeded earnings (as defined) by $174 million as a result of
 special charges and the current year impact of accounting changes.
</TABLE>
    
 
   
    The above ratios are computed on a total enterprise basis including Ashland
and its consolidated subsidiaries, plus their share of significant affiliates
accounted for on the equity method that are 50% owned or whose indebtedness has
been directly or indirectly guaranteed by Ashland or its consolidated
subsidiaries. Earnings consist of income before income taxes, minority interest
and the cumulative effect of accounting changes, adjusted to exclude fixed
charges (excluding capitalized interest) and undistributed earnings of equity
method affiliates excluded from the total enterprise. Fixed charges consist of
interest incurred on indebtedness, the portion of operating lease rentals deemed
representative of the interest factor and the amortization of debt expense.
    
 
                         DESCRIPTION OF DEBT SECURITIES

certain general terms and provisions of the Debt Securities to which any

    The Debt Securities will be general obligations of the Company and may be
subordinated to "Superior Indebtedness" (as defined below) of the Company to the
extent set forth in the Prospectus Supplement relating thereto. See
"Subordination of Subordinated Securities" below. Unless otherwise set forth in
the applicable Prospectus Supplement, Senior Securities will be issued under an
Indenture dated as of August 15, 1989, as amended and restated as of August 15,
1990, between the Company and Citibank, N.A., as Trustee, pursuant to which the
Company has issued an aggregate of $1,299,990,000 senior debt securities.
Subordinated Securities will be issued under an Indenture between the Company
and a commercial bank to be selected as Trustee. A copy of the form of each
Indenture has been filed as an exhibit to the Registration Statement filed with
the Commission. The following discussion of certain provisions of the Indentures
is a summary only and does not purport to be a complete description of the terms
and provisions of the Indentures. Accordingly, the following discussion is
qualified in its entirety by reference to the provisions of the Indentures,
including the definition therein of the terms used below with their initial
letters capitalized.

GENERAL
 
   
    The Indentures do not limit the aggregate principal amount of Debt
Securities which may be issued thereunder. The Debt Securities may be issued in
one or more series as may be authorized from time to time by Ashland. Reference
is made to the applicable Prospectus Supplement for the following terms of the
Debt Securities: (i) the title and the limit on the aggregate principal amount
of the Debt Securities; (ii) the date or dates on which the Debt Securities will
mature; (iii) the rate or rates (which may be fixed or variable) per annum, if
any, or the method of determining such rate or rates, at which the Debt
Securities will bear interest; (iv) the date or dates from which such interest
shall accrue and the date or dates on which such interest will be payable; (v)
the currency or currencies or units of two or more currencies in which the Debt
Securities are denominated and principal and interest may be payable, and for
which the Debt Securities may be purchased, which may be in United States
dollars, a foreign currency or currencies or units of two or more foreign
currencies; (vi) whether such Debt Securities are to be Senior Securities or
Subordinated Securities; (vii) any redemption or sinking fund terms or certain
other specific terms; (viii) any Event of Default or covenant with respect to
the Debt Securities of a particular series, if not set forth herein; (ix)
whether the Debt Securities will be issued as Registered Securities (as defined
below) or as Bearer Securities (as defined below); (x) whether the Debt
Securities are to be issued in whole or in part in the form of one or more
Global Securities (as defined below) and, if so, the identity of the depositary
for such Global Security or Securities; and (xi) any other terms of such series
(which terms shall not be inconsistent with the provisions of the Subordinated
Indenture or the Senior Indenture, as the case may be). Unless otherwise
indicated in the applicable Prospectus Supplement, principal, premium, if any,
and interest, if any, will be payable, and the Debt Securities will be
transferable, at the corporate trust office of the respective Trustee, provided
that payment of interest may be made at the option of Ashland by check mailed to
the address of the person entitled thereto as it appears in the respective Debt
Securities register.
    
 
    The Debt Securities will be unsecured. Senior Securities will rank on a
parity with all other unsecured and unsubordinated indebtedness of Ashland.
Subordinated Securities will be subordinated to certain present and future
superior indebtedness of Ashland. See "Subordination of Subordinated Securities"
below.
 
   
    The Debt Securities may be issued in fully registered form without coupons
("Registered Securities") or in bearer form with or without coupons ("Bearer
Securities"). Debt Securities denominated in U.S. dollars will be issued, unless
otherwise set forth in the applicable Prospectus Supplement, in denominations of
$1,000 or an integral multiple thereof for Registered Securities, and in
denominations of $5,000 or an integral multiple thereof for Bearer Securities.
Unless otherwise indicated in the applicable Prospectus Supplement, the Debt
Securities will be only Registered Securities. No service charge will be made
for any transfer or exchange of such Debt Securities, but Ashland may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith.
    
 
    Special Federal income tax and other considerations relating to Debt
Securities denominated in foreign currencies or units of two or more foreign
currencies will be described in the applicable Prospectus Supplement.
 
    Unless otherwise indicated in the applicable Prospectus Supplement, the
covenants contained in the Indentures and the Debt Securities will not afford
holders of Debt Securities protection in the event of a highly leveraged
transaction involving the Company.
 
EXCHANGE, REGISTRATION AND TRANSFER
 
   
    Registered Securities (other than Global Securities) of any series will be
exchangeable for other Registered Securities of the same series and of a like
aggregate principal amount and tenor of different authorized denominations. In
addition, if Debt Securities of any series are issuable as both Registered
Securities and Bearer Securities, at the option of the holder upon request
confirmed in writing, and
    
 
                                       5
<PAGE>
subject to the terms of the Indenture, Bearer Securities (with all unmatured
coupons, except as provided below, and all matured coupons in default) of such
series will be exchangeable into Registered Securities of the same series of any
authorized denominations and of a like aggregate principal amount and tenor.
Bearer Securities with coupons appertaining thereto surrendered in exchange for
Registered Securities between a Regular Record Date or a Special Record Date and
the relevant date for payment of interest shall be surrendered without the
coupon relating to such date for payment of interest and interest will not be
payable in respect of the Registered Security issued in exchange for such Bearer
Security, but will be payable only to the holder of such coupon when due in
accordance with the terms of the Indenture. Bearer Securities will not be issued
in exchange for Registered Securities.
 
   
    Debt Securities may be presented for exchange as provided above, and
Registered Securities may be presented for registration of transfer (with the
form of transfer endorsed thereon duly executed), at the office of the Security
Registrar or at the office of any transfer agent designated by the Company for
such purpose with respect to any series of Debt Securities and referred to in an
applicable Prospectus Supplement, without service charge and upon payment of any
taxes and other governmental charges as described in the Indenture. Such
transfer or exchange will be effected upon the Security Registrar or such
transfer agent, as the case may be, being satisfied with the documents of title
and identity of the person making the request. The Company has appointed the
Trustee as Security Registrar for the Indenture. If a Prospectus Supplement
refers to any transfer agents (in addition to the Security Registrar) initially
designated by the Company with respect to any series of Debt Securities, the
Company may at any time rescind the designation of any such transfer agent or
approve a change in the location through which any such transfer agent acts,
except that, if Debt Securities of a series are issuable solely as Registered
Securities, the Company will be required to maintain a transfer agent in each
Place of Payment for such series, and if Debt Securities of a series are
issuable as Bearer Securities, the Company will be required to maintain (in
addition to the Security Registrar) a transfer agent in a Place of Payment for
such series located in Europe. The Company may at any time designate additional
transfer agents with respect to any series of Debt Securities.
    
 
   
    In the event of any redemption in part, the Company shall not be required
to: (i) issue, register the transfer of or exchange Debt Securities of any
series during a period beginning at the opening of business 15 days before any
selection of Debt Securities of that series to be redeemed and ending at the
close of business on (a) if Debt Securities of the series are issuable only as
Registered Securities, the day of mailing of the relevant notice of redemption
and (b) if Debt Securities of the series are issuable only as Bearer Securities,
the day of the first publication of the relevant notice of redemption or (c) if
Debt Securities of the series are issuable as Registered Securities and Bearer
Securities and there is no publication of the relevant notice of redemption, the
day of mailing of the relevant notice of redemption, otherwise the date of such
publication; (ii) register the transfer of or exchange any Registered Security,
or portion thereof, called for redemption, except the unredeemed portion of any
Registered Security being redeemed in part; or (iii) exchange any Bearer
Security called for redemption, except to exchange such Bearer Security for a
Registered Security of that series and like tenor which is immediately
surrendered for redemption.
    
 
    For a discussion of restrictions on the exchange, registration and transfer
of Global Securities, see "Global Securities".
 
PAYMENT AND PAYING AGENTS
 
   
    Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal, premium, if any, and interest on Bearer Securities will be
payable, subject to any applicable laws and regulations, at the offices of such
Paying Agents outside the United States as the Company may designate from time
to time, and payment of interest on Bearer Securities with coupons appertaining
thereto on any Interest Payment Date will be made only against surrender of the
coupon relating to such Interest Payment Date. No payment with respect to any
Bearer Security will be made at any
    
 
                                       6
<PAGE>
office or agency of the company in the United States or by check mailed to any
address in the United States or by transfer to an account maintained with a bank
located in the United States. Notwithstanding the foregoing, payments of
principal, premium, if any, and interest on Bearer Securities denominated and
payable in U.S. dollars will be made at the office of the Company's Paying Agent
in the Borough of Manhattan, The City of New York, if (but only if) payment of
the full amount thereof in U.S. dollars at all offices or agencies outside the
United States is illegal or effectively precluded by exchange controls or other
similar restrictions.
 
    Unless otherwise indicated in an applicable Prospectus Supplement, payment
of principal, premium, if any, and any interest on Registered Securities will be
made at the office of such Paying Agent or Paying Agents as the Company may
designate from time to time, except that at the option of the Company, payment
of any interest may be made by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register. Unless
otherwise indicated in an applicable Prospectus Supplement, payment of any
installment of interest on Registered Securities will be made to the Person in
whose name such Registered Security is registered at the close of business on
the Regular Record Date for such interest.
 
   
    Unless otherwise indicated in an applicable Prospectus Supplement, the
Corporate Trust Office of the Trustee in the Borough of Manhattan, The City of
New York, will be designated as the Company's sole Paying Agent for payments
with respect to Debt Securities that are issuable solely as Registered
Securities and as the Company's Paying Agent in the Borough of Manhattan, The
City of New York, for payments with respect to Debt Securities (subject to the
limitation described above in the case of Bearer Securities) that are issuable
solely as Bearer Securities or as both Registered Securities and Bearer
Securities. Any Paying Agents outside the United States and any other Paying
Agents in the United States initially designated by the Company for the Debt
Securities will be named in an applicable Prospectus Supplement. The Company may
at any time designate additional Paying Agents or rescind the designation of any
Paying Agent or approve a change in the office through which any Paying Agent
acts, except that, if Debt Securities of a series are issuable solely as
Registered Securities, the Company will be required to maintain a Paying Agent
in each Place of Payment for such series and, if Debt Securities of a series are
issuable as Bearer Securities, the Company will be required to maintain (i) a
Paying Agent in the Borough of Manhattan, The City of New York, for payments
with respect to any Registered Securities of the series (and for payments with
respect to Bearer Securities of the series in the circumstances described above,
but not otherwise), and (ii) a Paying Agent in a Place of Payment located
outside the United States where Debt Securities of such series and any coupons
appertaining thereto may be presented and surrendered for payment; provided that
if the Debt Securities of such series are listed on The International Stock
Exchange of the United Kingdom and the Republic of Ireland Limited or the
Luxembourg Stock Exchange or any other stock exchange located outside the United
States and such stock exchange shall so require, the Company will maintain a
Paying Agent in London or Luxembourg or any other required city located outside
the United States, as the case may be, for the Debt Securities of such series.
    
 
   
    All moneys paid by the Company to a Paying Agent for the payment of
principal, premium, if any, or interest on any Debt Security or coupon that
remains unclaimed at the end of two years after such principal, premium or
interest shall have become due and payable will be repaid to the Company and the
holder of such Debt Security or coupon will thereafter look only to the Company
for payment thereof.
    
 
GLOBAL SECURITIES
 
    The Debt Securities of a series issued under the Indentures may be issued in
whole or in part in the form of one or more global securities (the "Global
Securities") that will be deposited with, or on behalf of, a depositary (the
"Depositary") identified in the Prospectus Supplement relating to such series.
Global Securities may be issued in either registered or bearer form and in
either temporary or permanent form. Unless and until it is exchanged in whole or
in part for the individual Debt Securities
 
                                       7
<PAGE>
represented thereby, a Global Security may not be transferred except as a whole
by the Depositary for such Global Security to a nominee of such Depositary or by
a nominee of such Depositary to such Depositary or another nominee of such
Depositary or by the Depositary or any nominee to a successor Depositary or any
nominee of such successor.
 
    The specific terms of the depositary arrangement with respect to a series of
Debt Securities will be described in the Prospectus Supplement relating to such
series. Ashland anticipates that the following provisions will generally apply
to depositary arrangements.
 
    Upon the issuance of a Global Security in registered form, the Depositary
for such Global Security or its nominee will credit, on its book-entry
registration and transfer system, the respective principal amounts of the
individual Debt Securities represented by such Global Security to the accounts
of persons that have accounts with such Depositary. Such accounts shall be
designated by the dealers, underwriters or agents with respect to such Debt
Securities or by Ashland if such Debt Securities are offered and sold directly
by Ashland. Ownership of beneficial interests in a Global Security will be
limited to persons that have accounts with the applicable Depositary
("participants") or persons that may hold interests through participants.
Ownership of beneficial interests in such Global Security will be shown on, and
the transfer of that ownership will be effected only through, records maintained
by the applicable Depositary or its nominee (with respect to interests of
participants) and the records of participants (with respect to interests of
persons other than participants). The laws of some states require that certain
purchasers of securities take physical delivery of such securities in definitive
form. Such limits and such laws may impair the ability to transfer beneficial
interests in a Global Security.
 
    So long as the Depositary for a Global Security, or its nominee, is the
registered owner of such Global Security, such Depositary or such nominee, as
the case may be, will be considered the sole owner or holder of the Debt
Securities represented by such Global Security for all purposes under the
Indenture governing such Debt Securities. Except as provided below, owners of
beneficial interests in a Global Security will not be entitled to have any of
the individual Debt Securities of the series represented by such Global Security
registered in their names, will not receive or be entitled to receive physical
delivery of any such Debt Securities of such series in definitive form and will
not be considered the owners or holders thereof under the Indenture governing
such Debt Securities.
 
    Payments of principal of, premium, if any, and interest, if any, on
individual Debt Securities represented by a Global Security registered in the
name of a Depositary or its nominee will be made to the Depositary or its
nominee, as the case may be, as the registered owner of the Global Security
representing such Debt Securities. Neither Ashland, the Trustee for such Debt
Securities, any paying agent (a "Paying Agent"), nor the Registrar for such Debt
Securities will have any responsibility or liability for any aspect of the
records relating to or payments made by the Depositary or any participants on
account of beneficial ownership interests of the Global Security for such Debt
Securities or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.
 
    Ashland expects that the Depositary for a series of Debt Securities or its
nominee, upon receipt of any payment of principal, premium or interest in
respect of a permanent Global Security representing any of such Debt Securities,
immediately will credit participants' accounts with payments in amounts
proportionate to their respective beneficial interests in the principal amount
of such Global Security for such Debt Securities as shown on the records of such
Depositary or its nominee. Ashland also expects that payments by participants to
owners of beneficial interests in such Global Security held through such
participants will be governed by standing instructions and customary practices,
as is now the case with securities held for the accounts of customers in bearer
form or registered in "street name". Such payments will be the responsibility of
such participants.
 
    If the Depositary for a series of Debt Securities is at any time unwilling,
unable or ineligible to continue as Depositary and a successor Depositary is not
appointed by Ashland within 90 days,
 
                                       8
<PAGE>
Ashland will issue individual Debt Securities of such series in exchange for the
Global Security or Securities representing such series of Debt Securities. In
addition, Ashland may at any time in its sole discretion, subject to any
limitations described in the Prospectus Supplement relating to such Debt
Securities, determine not to have any Debt Securities of a series represented by
one or more Global Securities and, in such event, will issue individual Debt
Securities of such series in exchange for the Global Security or Securities
representing such series of Debt Securities. Further, if Ashland so specifies
with respect to the Debt Securities of a series, an owner of a beneficial
interest in a Global Security representing Debt Securities of such series may,
on terms acceptable to Ashland, the Trustee, and the Depositary for such Global
Security, receive individual Debt Securities of such series in exchange for such
beneficial interests, subject to any limitations described in the Prospectus
Supplement relating to such Debt Securities. In any such instance, an owner of a
beneficial interest in a Global Security will be entitled to physical delivery
of individual Debt Securities of the series represented by such Global Security
equal in principal amount to such beneficial interest and to have such Debt
Securities registered in its name. Individual Debt Securities of such series so
issued will be issued in denominations, unless otherwise specified by Ashland,
of $1,000 and integral multiples thereof.
 
    If so specified in an applicable Prospectus Supplement, all or any portion
of the Debt Securities of a series that are issuable as Bearer Securities
initially will be represented by one or more temporary Global Securities, with
or without interest coupons, to be deposited with a Common Depositary in London
for Morgan Guaranty Trust Company of New York, Brussels Office, as operator of
the Euroclear System ("Euroclear") and Centrale de Livraison de Valeurs
Mobilieres S.A. ("CEDEL") for credit to the respective accounts of the
beneficial owners of such Debt Securities (or to such other accounts as they may
direct). On and after the exchange date determined as provided in any such
temporary Global Security and described in an applicable Prospectus Supplement,
each such temporary Global Security will be exchangeable for definitive Debt
Securities in bearer form, registered form, or definitive global form
(registered or bearer), or any combination thereof, as specified in an
applicable Prospectus Supplement. No Bearer Security (including a Debt Security
in definitive global bearer form) delivered in exchange for a portion of a
temporary Global Security shall be mailed or otherwise delivered to any location
in the United States in connection with such exchange.
 
    Unless otherwise specified in an applicable Prospectus Supplement, Ashland
or its agent must receive a certificate signed by Euroclear or CEDEL, as the
case may be, prior to the delivery of a definitive Bearer Security, and prior to
the actual payment of interest in respect of the applicable portion of the
temporary Global Security payable in respect of an Interest Payment Date
occurring prior to the delivery of a definitive Debt Security. Such certificate
must be based on statements provided to Euroclear or CEDEL by its member
organizations. Such certificate must be dated on the date of the earlier of the
first actual payment of interest on the Debt Security and the date of delivery
of the Debt Security in definitive form, and must state that on such date the
Debt Security is owned by (i) a person that is not a United States person and is
not a financial institution holding the obligation for purposes of resale during
the Restricted Period, (ii) a United States person that is either (A) the
foreign branch of a United States financial institution purchasing for its own
account and not for resale during the Restricted Period or (B) a United States
person who acquired its interest through the foreign branch of a United States
financial institution and who holds the obligation through such financial
institution, provided that in either case (A) or (B) the United States financial
institution either provides a certificate stating that it agrees to comply with
the requirements of Section 165(j)(3)(A), (B) or (C) of the Internal Revenue
Code of 1986, as amended, and the regulations thereunder or has provided a valid
blanket certificate stating that the financial institution will comply with such
requirements or (iii) a financial institution holding for purposes of resale
during the Restricted Period, and such financial institution certifies in
addition that it has not acquired the obligation for purposes of resale directly
or indirectly to a United States person or to a person within
 
                                       9
<PAGE>
the United States or its possessions. As used herein, the term "Restricted
Period" means (i) the period from the closing date until 40 days thereafter or
(ii) any time if the obligation is held as part of an unsold allotment or
subscription.
 
    Each of Euroclear and CEDEL will in such circumstances credit the interest
received by it in respect of such temporary Global Security to the accounts of
the beneficial owners thereof (or to such other accounts as they may direct).
 
    The beneficial owner of a Debt Security represented by a definitive Global
Security in bearer form may, upon not less than 30 days' written notice to the
Trustee, given by it through either Euroclear or CEDEL, exchange its interest in
such definitive Global Security for a definitive Bearer Security or Securities,
or a definitive Registered Security or Securities of any authorized
denomination. No individual definitive Bearer Security will be delivered in or
to the United States.
 
CERTAIN COVENANTS OF ASHLAND WITH RESPECT TO SENIOR SECURITIES
 
    LIMITATIONS ON LIENS. Unless otherwise provided in the applicable Prospectus
Supplement, Ashland will agree that neither it nor any Subsidiary (as defined in
the Senior Indenture) will issue, assume or guarantee any notes, bonds,
debentures or other similar evidences of indebtedness for money borrowed
("Debt") secured by a mortgage, lien, pledge or other encumbrance ("Mortgages")
upon any of its property or any property of such Subsidiary, real or personal,
located in the continental United States of America without effectively
providing that the Senior Securities (together with, if Ashland so determines,
any other indebtedness or obligation then existing and any other indebtedness or
obligation, thereafter created, ranking equally with the Senior Securities)
shall be secured equally and ratably with (or, at the option of Ashland, prior
to) such Debt so long as such Debt shall be so secured, except that the
foregoing provisions shall not apply to: (a) Mortgages existing on the date of
the Senior Indenture, (b) Mortgages affecting property of a corporation existing
at the time it becomes a Subsidiary or at the time it is merged into or
consolidated with Ashland or a Subsidiary, (c) Mortgages on property (i)
existing at the time of acquisition thereof, (ii) to secure payment of all or
part of the purchase price thereof, (iii) to secure Debt incurred prior to, at
the time of or within 24 months after acquisition thereof for the purpose of
financing all or part of the purchase price thereof or (iv) assumed or incurred
in connection with the acquisition thereof, (d) Mortgages on property to secure
all or part of the cost of repairing, altering, constructing, improving,
exploring, drilling or developing such property, or to secure Debt incurred to
provide funds for any such purpose, (e) Mortgages on (i) pipelines, gathering
systems, pumping or compressor stations, pipeline storage facilities or other
related facilities, (ii) tank cars, tank trucks, tank vessels, barges, tow boats
or other vessels or boats, drilling barges, drilling platforms, or other movable
railway, automotive, aeronautic or marine facilities, (iii) office buildings,
laboratory and research facilities, retail service stations, retail or wholesale
sales facilities, terminals, bulk plants, warehouses or storage or distribution
facilities, (iv) manufacturing facilities other than units for the refining of
crude oil, (v) the equipment of any of the foregoing or (vi) any "margin stock"
or "margin security" within the meaning of Regulation U or Regulation G of the
Board of Governors of the Federal Reserve System as amended from time to time,
(f) Mortgages on current assets or other personal property (other than shares of
stock or indebtedness of Subsidiaries) to secure loans maturing not more than
one year from the date of the creation thereof or to secure any renewal thereof
for not more than one year at any one time, (g) Mortgages which secure
indebtedness owing by a Subsidiary to Ashland or a Subsidiary, (h) Mortgages on
property of any Subsidiary principally engaged in a financing or leasing
business, (i) Mortgages upon the oil, gas or other minerals produced or to be
produced (or proceeds thereof) from properties which shall have been acquired or
shall have become producing subsequent to August 15, 1977, if, in respect to
each such Mortgage it shall have been given to secure indebtedness incurred to
pay or to reimburse the cost (incurred subsequent to the date of the acquisition
of such property or August 15, 1977, whichever shall be later) of drilling or
equipping such property and (j) any extension, renewal or replacement (or
successive extensions, renewals or replacements), in whole or in part, of any
Mortgage referred to in the foregoing clauses (a) to (i) inclusive or of any
Debt secured thereby,
 
                                       10
<PAGE>
PROVIDED that the principal amount of Debt secured thereby shall not exceed the
principal amount of Debt so secured at the time of such extension, renewal or
replacement, and that such extension, renewal or replacement Mortgage shall be
limited to all or part of substantially the same property which secured the
Mortgage extended, renewed or replaced (plus improvements on such property).
Notwithstanding the above, Ashland and any one or more Subsidiaries may issue,
assume or guarantee Debt secured by Mortgages which would otherwise be subject
to the foregoing restrictions in an aggregate principal amount which, together
with the aggregate outstanding principal amount of all other Debt of Ashland and
its Subsidiaries which would otherwise be subject to the foregoing restrictions,
does not at any one time exceed 5% of the stockholders' equity in Ashland and
its consolidated subsidiary companies as shown on the audited consolidated
balance sheet contained in the latest annual report to stockholders of Ashland.
The following types of transactions, among others, shall not be deemed to create
Debt secured by Mortgages: (1) the sale or other transfer of oil, gas or other
minerals in place for a period of time until, or in an amount such that, the
transferee will realize therefrom a specified amount (however determined) of
money or such minerals, or the sale or other transfer of any other interest in
property of the character commonly referred to as an oil payment or a production
payment and (2) Mortgages required by any contract or statute in order to permit
Ashland or a Subsidiary to perform any contract or subcontract made by it with
or at the request of the United States, any State or any department, agency or
instrumentality of either.
 
    LIMITATIONS ON SALE AND LEASE-BACK.  Unless otherwise provided in the
applicable Prospectus Supplement, Ashland will agree that neither it nor any
Subsidiary will enter into any arrangement with any bank, insurance company or
other lender or investor, or to which any such lender or investor is a party,
providing for the leasing to Ashland or a Subsidiary for a period of more than
three years of any real property located in the continental United States
(except a lease for a temporary period not to exceed three years by the end of
which it is intended that the use of such real property by the lessee will be
discontinued) which has been or is to be sold or transferred by Ashland or a
Subsidiary to such lender or investor or to any Person or organization to which
funds have been or are to be advanced by such lender or investor on the security
of the leased property ("Sale and Lease-Back Transactions") unless either: (a)
Ashland or such Subsidiary would be entitled to create Debt secured by a
Mortgage on the property to be leased, without equally and ratably securing the
Senior Securities or (b) Ashland (and in any such case Ashland covenants and
agrees that it will do so), within four months after the effective date of such
Sale and Lease-Back Transaction (whether made by Ashland or a Subsidiary),
applies to the retirement of Debt of Ashland maturing by the terms thereof more
than one year after the original creation thereof ("Funded Debt"), an amount
equal to the greater of (i) the net proceeds of the sale of the real property
leased pursuant to such arrangement or (ii) the fair value of the real property
so leased at the time of entering into such arrangement (as determined by the
Board of Directors); PROVIDED that the amount to be applied to the retirement of
Funded Debt shall be reduced by an amount equal to the sum of (a) the principal
amount of Senior Securities delivered, within four months after the effective
date of such arrangement, to the Trustee for retirement and cancellation and (b)
the principal amount of other Funded Debt voluntarily retired by Ashland within
such four-month period, excluding retirements of Senior Securities and other
Funded Debt pursuant to mandatory sinking fund or prepayment provisions or by
payment at maturity.
 
    LIMITATION ON CONSOLIDATIONS AND MERGERS.  The Senior Indenture provides
that Ashland will not consolidate with or merge into any other corporation or
convey or transfer its properties and assets substantially as an entirety to any
entity (other than a wholly owned subsidiary of Ashland, except in the event
that such a subsidiary is the surviving corporation in a consolidation or
merger) unless the successor or transferee is a domestic corporation that
assumes Ashland's obligations under the Senior Securities and the Senior
Indenture and certain other conditions are met.
 
SUBORDINATION OF SUBORDINATED SECURITIES
 
    The payment of the principal of, premium, if any, and interest on the
Subordinated Securities, including sinking fund payments, if any, will be
subordinated in right of payment, as set forth in the
 
                                       11
<PAGE>
Subordinated Indenture, to the prior payment in full of all Superior
Indebtedness of Ashland. Superior Indebtedness is defined as (a) the principal
of, premium, if any, and accrued and unpaid interest on (whether outstanding on
the date of execution of the Subordinated Indenture or thereafter created,
incurred or assumed) (i) indebtedness of Ashland for money borrowed (other than
the Subordinated Securities), (ii) guarantees by Ashland of indebtedness for
money borrowed of any other person, (iii) indebtedness evidenced by notes,
debentures, bonds or other instruments of indebtedness for the payment of which
Ashland is responsible or liable, by guarantees or otherwise, (iv) obligations
of Ashland under any agreement relating to any interest rate or currency swap,
interest rate cap, interest rate collar, interest rate future, currency exchange
or forward currency transaction, or any similar interest rate or currency
hedging transaction and (v) obligations of Ashland under any agreement to lease,
or any lease of, any real or personal property which, in accordance with
generally accepted accounting principles, is classified on Ashland's balance
sheet as a liability and (b) modifications, renewals, extensions and refundings
of any such indebtedness, liability, obligation or guarantee; unless, in the
instrument created or evidencing the same or pursuant to which the same is
outstanding, it is provided that such indebtedness, liability, obligation or
guarantee, or such modification, renewal, extension or refunding thereof, is not
superior in right of payment to the Subordinated Securities; PROVIDED, HOWEVER,
that Superior Indebtedness shall not be deemed to include (i) any obligations of
Ashland to any subsidiary and (ii) any other indebtedness, guarantee or
obligation of Ashland of the type set forth above which is subordinate or junior
in ranking in any respect to any other indebtedness, guarantee or obligation of
Ashland.
 
    No payment by Ashland on account of principal of, premium, if any, or
interest on the Subordinated Securities, including sinking fund payments, if
any, may be made if any default or event of default with respect to any Superior
Indebtedness shall have occurred and be continuing and (unless such default or
event of default is the failure by Ashland to pay principal or interest on any
instrument constituting Superior Indebtedness) written notice thereof shall have
been given to the Trustee by Ashland or to Ashland and the Trustee by the
Holders of at least 10% in principal amount of any kind or category of any
Superior Indebtedness (or a representative or trustee on their behalf). Ashland
may resume payments on the Subordinated Securities (unless otherwise prohibited
by the related Indenture) if (i) such default is cured or waived or (ii) unless
such default is the failure of Ashland to pay principal or interest on any
Superior Indebtedness, 120 days pass after the notice is given if such default
is not the subject of judicial proceedings. In the event that any Subordinated
Security is declared due and payable before the date specified therein as the
fixed date on which the principal thereof is due and payable, or upon any
payment or distribution of assets of Ashland to creditors upon any dissolution,
winding up, liquidation or reorganization, whether voluntary or involuntary or
in bankruptcy, insolvency, receivership or other proceedings, all principal of
(and premium, if any) and interest due or to become due on all Superior
Indebtedness must be paid in full before the Holders of Subordinated Securities
are entitled to receive or take any payment (other than shares of stock or
subordinated indebtedness provided by a plan of reorganization or adjustment
which does not alter the rights of Holders of Superior Indebtedness without such
Holders' consent). Subject to the payment in full of all Superior Indebtedness,
the Holders of the Subordinated Securities are to be subrogated to the rights of
the Holders of Superior Indebtedness to receive payments or distribution of
assets of Ashland applicable to Superior Indebtedness until the Subordinated
Securities are paid in full.
 
    By reason of such subordination, in the event of insolvency, creditors of
Ashland who are Holders of Superior Indebtedness, as well as certain general
creditors of Ashland, may recover more, ratably, than the Holders of the
Subordinated Securities.
 
    The Subordinated Indenture will not limit the amount of Superior
Indebtedness or Debt Securities which may be issued by Ashland or any of its
subsidiaries.

MODIFICATION OF THE INDENTURES
 
    The Indentures provide that the Company and the Trustee thereunder may,
without the consent of any Holders of Debt Securities, enter into supplemental
indentures for the purposes, among other things, of adding to the Company's
covenants, adding additional Events of Default, establishing the form or terms
of the Debt Securities as permitted under the Indentures or, provided such
action shall not adversely affect the interests of the Holders of Debt
Securities in any material respect, curing ambiguities or inconsistencies in
such Indentures or making other provisions.
 
    The Indentures contain provisions permitting the Company, with the consent
of the Holders of not less than 66 2/3% in principal amount of the Outstanding
Securities (as defined in the Indentures) of each affected series, to execute
supplemental indentures adding any provisions to or changing or eliminating any
of the provisions of the Indentures or modifying the rights of the Holders of
Debt Securities of such series, except that no such supplemental indenture may,
without the consent of the Holders of all of the Outstanding Securities affected
thereby, among other things: (i) change the maturity of the principal of, or any
installment of principal of or interest on, any of the Debt Securities; (ii)
reduce the principal amount thereof (or any premium thereon) or the rate of
interest thereon; (iii) change the currency, currencies or currency unit or
units in which, any of the Debt Securities or any premium or interest thereon is
payable; (iv) change any obligation of the Company to maintain an office or
agency in the places and for the purposes required by such Indentures; (v)
impair the right to institute suit for the enforcement of any such payment on or
after the applicable maturity date; (vi) reduce the percentage in principal
amount of the Outstanding Securities of any series, the consent of the Holders
of which is required for any such supplemental indenture or for any waiver of
compliance with certain provisions of, or of certain defaults under, such
Indentures; or (vii) with certain exceptions, modify the provisions for the
waiver of certain covenants and defaults and any of the foregoing provisions.
 
WAIVER OF CERTAIN COVENANTS
 
    The Indentures provide that the Company will not be required to comply with
certain restrictive covenants (including those described above under "Certain
Restrictive Provisions") if the Holders of not less than 66 2/3% in principal
amount of each series of Outstanding Securities affected thereby waive
compliance with such restrictive covenants.
 
EVENTS OF DEFAULT, NOTICE AND WAIVER
 
    An Event of Default in respect of any series of Debt Securities (unless it
is either inapplicable to a particular series or has been modified or deleted
with respect to any particular series) is defined in the Indentures to be: (i) a
default for 30 days in the payment of any installment of interest upon any of
the Debt Securities of such series when due; (ii) a default in the payment of
principal of (or premium, if any, on) any of the Debt Securities of such series
when due; (iii) a default for 30 days in the deposit of any sinking fund payment
when the same becomes due by the terms of the Debt Securities of such series;
(iv) a default by the Company in the performance, or breach, of any of its other
covenants or warranties in the applicable Indentures which shall not have been
remedied for a period of 60 days after notice from the Trustee thereunder or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of such series; (v) certain events of bankruptcy, insolvency or reorganization
of the Company; and (vi) any other Event of Default provided with respect to
Debt Securities of that series.
 
    The Indentures provide that if an Event of Default specified therein in
respect of any series of Outstanding Securities issued under such Indentures
shall have happened and be continuing, either the Trustee thereunder or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of such series may declare the principal of all of the Outstanding Securities of
such series to be immediately due and payable.
 
    The Indentures provide that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may direct the
time, method and place of conducting any
 
                                       13
<PAGE>
proceeding for any remedy available to the Trustee thereunder, or exercising any
trust or power conferred on such Trustee, with respect to the Debt Securities of
such series, provided that such Trustee may act in any way that is not
inconsistent with such directions and may decline to act if any such direction
is contrary to law or to such Indentures or would involve such Trustee in
personal liability.
 
    The Indentures provide that the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series may on behalf of
the Holders of all of the Outstanding Securities of such series waive any past
default under the Indentures with respect to such series and its consequences,
except a default (i) in the payment of the principal of (or premium, if any) or
interest on any of the Debt Securities of such series or (ii) in respect of a
covenant or provision of such Indentures which, under the terms of such
Indentures, cannot be modified or amended without the consent of the Holders of
all of the Outstanding Securities of such series affected thereby.
 
    The Indentures contain provisions entitling the Trustee, subject to the duty
of the Trustee during an Event of Default in respect of any series of Debt
Securities to act with the required standard of care, to be indemnified by the
Holders of the Debt Securities of such series before proceeding to exercise any
right or power under such Indentures at the request of the Holders of the Debt
Securities of such series.
 
    The Indentures provide that the Trustee will, within 90 days after the
occurrence of a default in respect of any series of Debt Securities, give to the
Holders of the Debt Securities of such series notice of such uncured and
unwaived default known to it; PROVIDED, HOWEVER, that, except in the case of a
default in the payment of the principal of (or premium, if any) or interest on,
or any sinking fund installment with respect to, any of the Debt Securities of
such series, such Trustee will be protected in withholding such notice if it in
good faith determines that the withholding of such notice is in the interest of
the Holders of the Debt Securities of such series; and PROVIDED FURTHER, that
such notice shall not be given until at least 30 days after the occurrence of an
Event of Default regarding the performance, or breach, of any covenant or
warranty of the Company under such Indentures other than for the payment of the
principal of (or premium, if any) or interest on, or any sinking fund
installment with respect to, any of the Debt Securities of such series. The term
"default" for the purpose of this provision only means any event that is, or
after notice or lapse of time, or both, would become, an Event of Default with
respect to the Debt Securities of such series.
 
    The Indentures require the Company to file annually with the Trustee
thereunder a certificate, executed by an officer of the Company, indicating
whether such officer has knowledge of any default under such Indentures.
 
MEETINGS
 
    The Indentures contain provisions for convening meetings of the Holders of
Debt Securities of a series if Debt Securities of that series are issuable as
Bearer Securities. A meeting may be called at any time by the Trustee, and, if
the Trustee fails to call a meeting within 21 days after receipt of a request
from the Company or the Holders of at least 10% in principal amount of the
Outstanding Securities of such series, the Company or such Holders may call a
meeting upon notice given in accordance with "Notices" below. Persons entitled
to vote a majority in principal amount of the Outstanding Securities of a series
shall constitute a quorum at a meeting of the Holders of Debt Securities of such
series; PROVIDED, HOWEVER, that if any action is to be taken at such meeting
with respect to a consent or waiver which is required to be given by the Holders
of not less than 66 2/3% in principal amount of the Outstanding Securities of a
series, the persons entitled to vote 66 2/3% in principal amount of the
Outstanding Securities of such series shall constitute a quorum. In the absence
of a quorum, a meeting called by the Company or the Trustee shall be adjourned
for a period of not less than 10 days, and in the absence of a quorum at any
such adjourned meeting, the meeting shall be further adjourned for a period of
not less than 10 days. Any resolution with respect to any request, demand,
authorization, direction, notice, consent, waiver or other action which may be
made, given or taken by the
 
                                       14
<PAGE>
Holders of a specified percentage in principal amount of Outstanding Securities
of a series may be adopted at a meeting or adjourned meeting duly reconvened at
which a quorum is present by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of that
series. Any resolution passed or decision taken at any meeting of Holders of
Debt Securities of any series duly held in accordance with the Indentures will
be binding on all Holders of Securities of that series and the related coupons.
With respect to any consent, waiver or other action which the Indentures
expressly provide may be given by the Holders of a specified percentage of
Outstanding Securities of any series affected thereby (acting as one class),
only the principal amount of Outstanding Securities of any series represented at
a meeting or adjourned meeting duly reconvened at which a quorum is present as
aforesaid and voting in favor of such action shall be counted for purposes of
calculating the aggregate principal amount of Outstanding Securities of all
series affected thereby favoring such action.
 
NOTICES
 
    Except as otherwise provided in the applicable Prospectus Supplement,
notices to Holders of Bearer Securities will be given by publication at least
once in a daily newspaper in The City of New York and London and in such other
city or cities as may be specified in such Bearer Securities and will be mailed
to such Persons whose names and addresses were previously filed with the Trustee
within the last two years under the Indentures, within the time prescribed for
the giving of such notice. Notices to Holders of Registered Securities will be
given by mail to the address of such Holders as they appear in the Security
Register.
 
TITLE
 
    Title to any Bearer Securities (including Bearer Securities in temporary or
definitive global bearer form) and any coupons appertaining thereto will pass by
delivery. The Company, the appropriate Trustee and any agent of the Company or
such Trustee may treat the bearer of any Bearer Security and the bearer of any
coupon and registered owner of any Registered Security as the absolute owner
thereof (whether or not such security or coupon shall be overdue and
notwithstanding any notice to the contrary) for the purpose of making payment
and for all other purposes.
 
REPLACEMENT OF SECURITIES AND COUPONS
 
    Any mutilated Debt Security and any Debt Security with a mutilated coupon
appertaining thereto will be replaced by the Company at the expense of the
Holder upon surrender of such mutilated Debt Security or Debt Security with a
mutilated coupon to the appropriate Trustee. Debt Securities or coupons that
become destroyed, stolen or lost will be replaced by the Company at the expense
of the Holder upon delivery to the appropriate Trustee of evidence of the
destruction, loss or theft thereof satisfactory to the Company and such Trustee;
in the case of any coupon which becomes destroyed, stolen or lost, such coupon
will be replaced (upon surrender to the appropriate Trustee of the Debt Security
with all appurtenant coupons not destroyed, stolen or lost) by issuance of a new
Debt Security in exchange for the Debt Security to which such coupon appertains.
In the case of a destroyed, lost or stolen Debt Security or coupon an indemnity
satisfactory to the appropriate Trustee and the Company may be required at the
expense of the Holder of such Debt Security or coupon before a replacement Debt
Security will be issued.
 
DEFEASANCE
 
    Unless the Prospectus Supplement relating to the Offered Securities provides
otherwise, the Company at its option (a) will be Discharged (as such term is
defined in the Indentures) from any and all obligations in respect of the
Offered Securities (except for certain obligations to register the transfer or
exchange of Debt Securities, replace stolen, lost or mutilated securities and
coupons, maintain paying agencies and hold moneys for payment in trust) or (b)
need not comply with certain restrictive covenants of the Indentures (including
those described above under "Certain Restrictive Provisions"), if there are
deposited with the Trustee, in the case of Debt Securities and coupons
denominated in U.S. dollars, U.S. Government Obligations (as defined in the
Indentures) or, in the case of Debt Securities and coupons denominated in a
foreign currency, Foreign Government Securities (as defined in the Indentures),
which through the payment of
 
                                       15
<PAGE>
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 Offered
Securities are payable all the principal of, and interest on, the Offered
Securities on the dates such payments are due in accordance with the terms of
the Offered Securities. As a condition to the Company's exercise of either such
option, the Company is required to deliver to the Trustee an opinion of counsel
to the effect that Holders of the Offered Securities will not recognize income,
gain or loss for Federal income tax purposes as a result of the deposit and
related defeasance and will be subject to Federal income tax in the same amount,
in the same manner and at the same times as would have been the case if such
deposit and related defeasance had not occurred. The deposit and the Discharge
or release from compliance with certain covenants described in the preceding
sentence may result in the Holders of the Offered Securities recognizing income,
gain or loss for Federal income tax purposes as a result of such deposit and
Discharge or release, and may result in the Holders recognizing income in a
manner or at times different than would have been the case if such deposit and
Discharge or release had not occurred.
 
CERTAIN RIGHTS TO REQUIRE PURCHASE OF SECURITIES BY ASHLAND UPON UNAPPROVED
CHANGE IN CONTROL AND DECLINE IN DEBT RATING
 
    In the event that (a) there occurs any Change in Control (as hereinafter
defined) of Ashland and (b) the prevailing rating of any series of the Debt
Securities issued under the Indentures on a date within 90 days following public
notice of such Change in Control shall be less than the rating on a specified
earlier date by the equivalent of at least one full rating category (as defined
in the Indentures), each Holder of Debt Securities of such series shall have the
right, at the Holder's option, to require Ashland to purchase all or any part of
the Holder's Debt Securities on the date (the "Repurchase Date") that is 100
days after the last to occur of (i) public notice of such Change in Control and
(ii) the rating decline, at 100% of the principal amount on the Repurchase Date,
plus accrued and unpaid interest to the Repurchase Date. Notwithstanding the
foregoing, if such a rating decline applies to less than all series of the Debt
Securities, the repurchase rights described above will apply only to those
series with respect to which there has been a rating decline.
 
    On or before the twenty-eighth day after the last to occur of public notice
of the Change in Control and the decrease in the rating of such Debt Securities,
Ashland is obligated to mail or cause to be mailed to all Holders of record of
such Debt Securities a notice regarding the Change in Control, the decrease in
the rating of the Debt Securities and the repurchase right. The notice shall
state the Repurchase Date, the date by which the repurchase right must be
exercised, the applicable price for such Debt Securities and the procedure which
the Holder must follow to exercise this right. Ashland shall cause a copy of
such notice to be published in a newspaper of general circulation in the Borough
of Manhattan, The City of New York. To exercise this right, the Holder of a Debt
Security must deliver on or before the tenth day before the Repurchase Date
written notice to Ashland (or an agent designated by Ashland for such purpose)
of the Holder's exercise of such right, together with the Debt Security with
respect to which the right is being exercised, duly endorsed for transfer. The
Company will comply with Rules 13e-4 and 14e-1 under the Exchange Act and any
other applicable securities laws in connection with any such repurchase of Debt
Securities.
 
    As used herein, a "Change in Control" shall be deemed to have occurred at
such time as (i) a "person" or "group" (within the meaning of Section 13(d) and
14(d)(2) of the Exchange Act) becomes the "beneficial owner" (as defined in Rule
13d-3 under the Exchange Act) of more than 50% of the then outstanding voting
stock of Ashland, otherwise than through a transaction consummated with the
prior approval of the Board of Directors of Ashland or (ii) during any period of
two consecutive years, individuals who at the beginning of such period
constitute Ashland's Board of Directors (together with any new director whose
election by Ashland's Board of Directors or whose nomination for election by
Ashland's shareholders was approved by a vote of at least two-thirds of the
Directors then still in office who either were Directors at the beginning of
such period or whose election or
 
                                       16
<PAGE>
nomination for election was previously so approved) cease for any reason to
constitute a majority of the Directors then in office. In considering whether to
approve a transaction which might otherwise constitute a Change in Control, the
Board of Directors of Ashland will be required to consider the interests of
stockholders, employees and other creditors of Ashland which may not necessarily
be consistent with the interests of Holders of Debt Securities. In considering
whether to pursue a transaction which might otherwise constitute a Change in
Control, a potential acquirer of the Company will be required to consider that,
to the extent the repurchase right becomes exercisable and is exercised by
Holders of Debt Securities of any series, sufficient funds must be made
available to make payment to such Holders. The Company cannot presently predict
the source of such funds, but expects that the source would be determined in the
context of the overall consideration of such a transaction.
 
GOVERNING LAW
 
    The Indentures, the Debt Securities and the coupons will be governed by, and
construed in accordance with, the laws of the State of New York.
 
THE TRUSTEE
 
    Citibank, N.A. is Trustee under the Senior Indenture and one other indenture
pursuant to which unsecured debt obligations of the Company are outstanding and
has other customary banking relationships with the Company and its affiliates.

                          DESCRIPTION OF CAPITAL STOCK
 
   
    The authorized stock of the Company consists of 150,000,000 shares of Common
Stock and 30,000,000 shares of Preferred Stock, issuable in series. On October
31, 1996, there were 64,599,228 shares of Common Stock and 6,000,000 shares of
Preferred Stock outstanding. 500,000 shares of Series A Participating Cumulative
Preferred Stock (the "Series Preferred Stock") have been authorized and are
reserved for issuance upon exercise of rights issued pursuant to the Rights
Agreement described below. As of October 31, 1996, an aggregate of 25,098,211
shares of Common Stock were reserved for issuance upon conversion of the
Company's 6 3/4% Convertible Subordinated Debentures, the Company's $3.125
Cumulative Convertible Preferred Stock (the "$3.125 Preferred Stock") and
issuance under the Company's various stock and compensation incentive plans.
    
 
    The following statements with respect to the capital stock of the Company
are subject to the detailed provisions of the Company's Second Restated Articles
of Incorporation, as amended (the "Restated Articles"), and By-laws, as amended
(the "By-laws"), as currently in effect. These statements do not purport to be
complete, or to give full effect to the terms of the provisions of statutory or
common law, and are subject to, and are qualified in their entirety by reference
to, the terms of the Restated Articles, By-laws and the Rights Agreement, which
are filed as Exhibits to the Registration Statement of which this Prospectus is
a part.
 
DESCRIPTION OF COMMON STOCK
 
    The holders of Common Stock are entitled to receive dividends as may be
declared from time to time by the Board of Directors of the Company (the "Board
of Directors") out of funds legally available therefor. The holders of Common
Stock are entitled to one vote per share on all matters submitted to a vote of
shareholders and have cumulative voting rights. Under cumulative voting, a
shareholder may multiply the number of shares owned by the number of directors
to be elected and cast this total number of votes for any one nominee or
distribute the total number of votes, in any proportion, among as many nominees
as the shareholder desires. Holders of Common Stock are entitled to receive,
upon any liquidation of the Company, all remaining assets available for
distribution to shareholders after satisfaction of the Company's liabilities and
the preferential rights of any Preferred Stock that may then be issued and
outstanding. The outstanding shares of Common Stock are, and the shares of
Common Stock issuable upon conversion of the $3.125 Preferred Stock and the
6 3/4% Convertible Subordinated Debentures will be, fully paid and
nonassessable. The holders of Common Stock have no preemptive, conversion or
redemption rights. The Transfer Agent and Registrar of Ashland's Common Stock is
Harris Trust and Savings Bank, Chicago, Illinois.
 
PREFERRED STOCK PURCHASE RIGHTS
 
   
    On May 16, 1996, the Company entered into a Rights Agreement with Harris
Trust and Savings Bank, as Rights Agent (the "Rights Agreement"), which is a
shareholder rights plan providing for a dividend of one Preferred Stock purchase
right for each outstanding share of Common Stock of the Company (the "Rights").
The dividend was issued to shareholders of record on the date of the adoption of
the Rights Agreement, and holders of shares of Common Stock issued subsequent to
that date are issued Rights with their shares. The Rights trade automatically
with shares of Common Stock and become exercisable only under certain
circumstances as described below. The Rights are designed to protect the
interests of the Company and its shareholders against coercive takeover tactics.
The purpose of the Rights is to encourage potential acquirers to negotiate with
the Company's Board of Directors prior to attempting a takeover and to provide
the Board with leverage in negotiating on behalf of all shareholders the terms
of any proposed takeover. The Rights may have certain anti-takeover effects. The
Rights should not, however, interfere with any merger or other business
combination approved by the Board of Directors.
    
 
                                       18
<PAGE>
   
    Until a Right is exercised, the holder of a Right, as such, will have no
rights as a shareholder of the Company including, without limitation, the right
to vote or to receive dividends. Upon becoming exercisable, each Right will
entitle the holder thereof to purchase from the Company one-thousandth of a
share of Series A Participating Cumulative Preferred Stock, without par value,
at a purchase price of $140 per Right, subject to adjustment (the "Purchase
Price"). In general, the Rights will not be exercisable until the earlier of (a)
such time as the Company learns that a person or group (including any affiliate
or associate of such person or group) has acquired, or has obtained the right to
acquire, beneficial ownership of 15% or more of the outstanding Common Stock
(such person or group being an "Acquiring Person"), unless provisions preventing
accidental triggering of the Rights apply and (b) the close of business on such
date, if any, as may be designated by the Board of Directors of the Company
following the commencement of, or first public disclosure of an intent to
commence, a tender or exchange offer for 15% or more of the outstanding Common
Stock (the earlier of such dates being called the "Distribution Date").
    
 
   
    In the event that, following Distribution Date, the Company is acquired in a
merger or other business combination by an Acquiring Person or an associate or
affiliate of an Acquiring Person that is a publicly traded corporation or 50% or
more of the Company's assets or assets representing 50% or more of the Company's
revenues or cash flow are sold, leased, exchanged or otherwise transferred (in
one or more transactions) to an Acquiring Person or an associate or affiliate of
an Acquiring Person that is a publicly traded corporation, each Right will
entitle its holder (subject to the next paragraph) to purchase, for the Purchase
Price, that number of common shares of such corporation which at the time of the
transaction would have a market value of twice the Purchase Price. In the event
the Company is acquired in a merger or other business combination by an
Acquiring Person or an associate or affiliate of an Acquiring Person that is not
a publicly traded entity or 50% or more of the Company's assets or assets
representing 50% or more of the Company's revenues or cash flow are sold,
leased, exchanged or otherwise transferred (in one or more transactions) to an
Acquiring Person or an associate or affiliate of an Acquiring Person that is not
a publicly traded entity, each Right will entitle its holder (subject to the
next paragraph) to purchase, for the Purchase Price, at such holder's option,
(a) that number of shares of the surviving corporation in the transaction with
such entity (which surviving corporation could be the Company) which at the time
of the transaction would have a book value of twice the Purchase Price, (b) that
number of shares of such entity which at the time of the transaction would have
a book value of twice the Purchase Price or (c) if such entity has an affiliate
which has publicly traded common shares, that number of common shares of such
affiliate which at the time of the transaction would have a market value of
twice the Purchase Price.
    
 
   
    Any Rights that are at any time beneficially owned by an Acquiring Person
(or any affiliate or associate of an Acquiring Person) will be null and void and
nontransferable and any holder of any such Right (including any purported
transferee or subsequent holder) will be unable to exercise or transfer any such
Right.
    
 
   
    The Rights will expire at the close of business on May 16, 2006 (the
"Expiration Date"), unless earlier redeemed. At any time prior to the earlier of
(a) such time as a person or group becomes an Acquiring Person and (b) the
Expiration Date, the Board of Directors may redeem the Rights in whole, but not
in part, at a price of $.01 per Right (which amount is subject to adjustment as
provided in the Rights Agreement).
    
 
   
    The foregoing description of the Rights does not purport to be complete and
is qualified in its entirety by the description of the Rights contained in the
Rights Agreement.
    
 
DESCRIPTION OF PREFERRED STOCK
 
    The following description of the terms of the Preferred Stock sets forth
certain general terms and provisions of the Preferred Stock to which a
Prospectus Supplement may relate. Specific terms of any series of the Preferred
Stock offered by a Prospectus Supplement will be described in the Prospectus
 
                                       19
<PAGE>
Supplement relating to such series of the Preferred Stock. The description set
forth below is subject to and qualified in its entirety by reference to the
Articles of Amendment to the Restated Articles establishing a particular series
of the Preferred Stock which will be filed with the Commission in connection
with the offering of such series of Preferred Stock.
 
    GENERAL.  Under the Restated Articles, the Board of Directors is authorized,
without further shareholder action, to provide for the issuance of up to
30,000,000 shares of Preferred Stock, in one or more series, and to fix the
designations, terms, and relative rights and preferences, including the dividend
rate, voting rights, conversion rights, redemption and sinking fund provisions
and liquidation values of each such series. The Company may amend from time to
time its Restated Articles to increase the number of authorized shares of
Preferred Stock. Any such amendment would require the approval of the holders of
66 2/3% of the outstanding shares of all series of Preferred Stock voting
together as a single class without regard to series. As of the date of this
Prospectus, the Company has one series of preferred stock outstanding.
 
    The Preferred Stock will have the dividend, liquidation, redemption,
conversion and voting rights set forth below unless otherwise provided in the
Prospectus Supplement relating to a particular series of the Preferred Stock.
Reference is made to the Prospectus Supplement relating to the particular series
of the Preferred Stock offered thereby for specific terms, including: (i) the
title and liquidation preference per share of such Preferred Stock and the
number of shares offered; (ii) the price at which such Preferred Stock will be
issued; (iii) the dividend rate (or method of calculation), the dates on which
dividends shall be payable and the dates from which dividends shall commence to
accumulate; (iv) any redemption or sinking fund provisions of such Preferred
Stock; (v) any conversion provisions of such Preferred Stock; (vi) the voting
rights, if any, of such Preferred Stock; and (vii) any additional dividend,
liquidation, redemption, sinking fund and other rights, preferences, privileges,
limitations and restrictions of such Preferred Stock.
 
    The Preferred Stock will, when issued, be fully paid and nonassessable.
 
    DIVIDEND RIGHTS.  The Preferred Stock will be preferred over the Common
Stock as to payment of dividends. Before any dividends or distributions (other
than dividends or distributions payable in Common Stock) on the Common Stock
shall be declared and set apart for payment or paid, the holders of shares of
each series of Preferred Stock shall be entitled to receive dividends (either in
cash, shares of Common Stock or Preferred Stock, or otherwise) when, as and if
declared by the Board of Directors, at the rate and on the date or dates as set
forth in the Prospectus Supplement. With respect to each series of Preferred
Stock, the dividends on each share of such series shall be cumulative from the
date of issue of such share unless some other date is set forth in the
Prospectus Supplement relating to any such series. Accruals of dividends shall
not bear interest.
 
    RIGHTS UPON LIQUIDATION.  The Preferred Stock shall be preferred over the
Common Stock as to assets so that the holders of each series of Preferred Stock
shall be entitled to be paid, upon the voluntary or involuntary liquidation,
dissolution or winding up of the Company and before any distribution is made to
the holders of Common Stock, the amount set forth in the Prospectus Supplement
relating to any such series, but in such case the holders of such series of
Preferred Stock shall not be entitled to any other or further payment. If upon
any such liquidation, dissolution or winding up of the Company its net assets
shall be insufficient to permit the payment in full of the respective amounts to
which the holders of all outstanding Preferred Stock are entitled, the entire
remaining net assets of the Company shall be distributed among the holders of
each series of Preferred Stock in amounts proportionate to the full amounts to
which the holders of each such series are respectively so entitled.

    REDEMPTION.  All shares of any series of Preferred Stock shall be redeemable
to the extent set forth in the Prospectus Supplement relating to any such
series. All shares of any series of Preferred Stock shall be convertible into
shares of Common Stock or into shares of any other series of Preferred Stock to
the extent set forth in the Prospectus Supplement relating to any such series.
 
    VOTING RIGHTS.  Unless otherwise provided in the Prospectus Supplement, the
holders of shares of Preferred Stock shall be entitled to one vote for each
share of Preferred Stock held by them on all matters properly presented to
shareholders, the holders of Common Stock and the holders of all series of
Preferred Stock voting together as one class.
 
$3.125 CUMULATIVE PREFERRED STOCK
 
   
    In May 1993, the Company issued 6,000,000 shares of $3.125 Preferred Stock
of which all such shares are currently outstanding. Annual cumulative dividends
of $3.125 per share are payable quarterly as and if declared by the Board of
Directors. Each share of $3.125 Preferred Stock is convertible at any time at
the option of the holder thereof into 1.546 shares of Common Stock, equivalent
to an initial conversion price of $32.343 for each share of Common Stock,
subject to adjustment in certain circumstances. The $3.125 Preferred Stock is
not redeemable prior to March 25, 1997. On and after such date, the $3.125
Preferred Stock is redeemable, in whole or in part, at the option of the
Company, at $51.88 per share during the period from March 25, 1997 to March 14,
1998, and declining ratably annually to $50 per share on or after March 15,
2003, plus in each case accrued and unpaid dividends to the redemption date. The
holders of $3.125 Preferred Stock generally have no voting rights, but have the
right to elect two additional directors of the Company if the equivalent of six
quarterly dividends payable on the $3.125 Preferred Stock are in arrears. In the
case of the voluntary or involuntary liquidation, dissolution or winding up of
the Company, holders of shares of $3.125 Preferred Stock are entitled to receive
the liquidation preference of $50 per share, plus an amount equal to any accrued
and unpaid dividends to the payment date.
    
 
DESCRIPTION OF DEPOSITARY SHARES
 
    GENERAL.  The Company may, at its option, elect to offer fractional shares
of Preferred Stock, rather than full shares of Preferred Stock. In the event
such option is exercised, the Company will issue to the public receipts for
Depositary Shares, each of which will represent a fraction (to be set forth in
the Prospectus Supplement relating to a particular series of Preferred Stock) of
a share of a particular series of Preferred Stock as described below.
 
    The shares of any series of Preferred Stock represented by Depositary Shares
will be deposited under a Deposit Agreement (the "Deposit Agreement") between
the Company and a bank or trust company selected by the Company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000 (the "Depositary"). Subject to the terms of the Deposit
Agreement, each owner of a Depositary Share will be entitled, in proportion to
the applicable fraction of a share of Preferred Stock represented by such
Depositary Share, to all the rights and preferences of the Preferred Stock
represented thereby (including dividend, voting, redemption and liquidation
rights).
 
    The Depositary Shares will be evidenced by depositary receipts issued
pursuant to the Deposit Agreement ("Depositary Receipts"). Depositary Receipts
will be distributed to those persons purchasing the fractional shares of
Preferred Stock in accordance with the terms of the offering. Copies of the
forms of Deposit Agreement and Depositary Receipt will be filed as exhibits to
the Registration Statement in connection with the offering of any such
Depositary Shares and the following summary is qualified in its entirety by
reference to such exhibits.
 
    Pending the preparation of definitive engraved Depositary Receipts, the
Depositary may, upon the written order of the Company, issue temporary
Depositary Receipts substantially identical to (and entitling the holders
thereof to all the rights pertaining to) the definitive Depositary Receipts but
not
 
                                       21
<PAGE>
in definitive form. Definitive Depositary Receipts will be prepared thereafter
without unreasonable delay, and temporary Depositary Receipts will be
exchangeable for definitive Depositary Receipts at the Company's expense.
 
    DIVIDENDS AND OTHER DISTRIBUTIONS.  The Depositary will distribute all cash
dividends or other cash distributions received in respect of the Preferred Stock
to the record holders of Depositary Shares relating to such Preferred Stock in
proportion to the number of such Depositary Shares owned by such holders.
 
    In the event of a distribution other than in cash, the Depositary will
distribute property received by it to the record holders of Depositary Shares
entitled thereto, unless the Depositary determines that it is not feasible to
make such distribution, in which case the Depositary may, with the approval of
the Company, sell such property and distribute the net proceeds from such sale
to such holders.
 
    REDEMPTION OF DEPOSITARY SHARES.  If a series of Preferred Stock represented
by Depositary Shares is subject to redemption, the Depositary Shares will be
redeemed from the proceeds received by the Depositary resulting from the
redemption, in whole or in part, of such series of Preferred Stock held by the
Depositary. The redemption price per Depositary Share will be equal to the
applicable fraction of the redemption price per share payable with respect to
such series of the Preferred Stock. Whenever the Company redeems shares of
Preferred Stock held by the Depositary, the Depositary will redeem as of the
same redemption date the number of Depositary Shares representing the shares of
Preferred Stock so redeemed. If fewer than all the Depositary Shares are to be
redeemed, the Depositary Shares to be redeemed will be selected by lot or PRO
RATA as may be determined by the Depositary.
 
    VOTING THE PREFERRED STOCK.  Upon receipt of notice of any meeting at which
the holders of the Preferred Stock are entitled to vote, the Depositary will
mail the information contained in such notice of meeting to the record holders
of the Depositary Shares relating to such Preferred Stock. Each record holder of
such Depositary Shares on the record date (which will be the same date as the
record date for the Preferred Stock) will be entitled to instruct the Depositary
as to the exercise of the voting rights pertaining to the amount of the
Preferred Stock represented by such holder's Depositary Shares. The Depositary
will endeavor, insofar as practicable, to vote the amount of the Preferred Stock
represented by such Depositary Shares in accordance with such instructions, and
the Company will agree to take all actions which may be deemed necessary by the
Depositary in order to enable the Depositary to do so. The Depositary will
abstain from voting shares of the Preferred Stock to the extent it does not
receive specific instructions from the holders of Depositary Shares representing
such Preferred Stock.
 
    AMENDMENT AND TERMINATION OF THE DEPOSITARY AGREEMENT.  The form of
Depositary Receipt evidencing the Depositary Shares and any provision of the
Deposit Agreement may at any time be amended by agreement between the Company
and the Depositary. However, any amendment which materially and adversely alters
the rights of the holders of Depositary Shares will not be effective unless such
amendment has been approved by the holders of at least a majority of the
Depositary Shares then outstanding. The Deposit Agreement may be terminated by
the Company or the Depositary only if (i) all outstanding Depositary Shares have
been redeemed or (ii) there has been a final distribution in respect of the
Preferred Stock in connection with any liquidation, dissolution or winding up of
the Company and such distribution has been distributed to the holders of
Depositary Receipts.
 
    CHARGES OF DEPOSITARY.  The Company will pay all transfer and other taxes
and governmental charges arising solely from the existence of the depositary
arrangements. The Company will pay charges of the Depositary in connection with
the initial deposit of the Preferred Stock and any redemption of the Preferred
Stock. Holders of Depositary Receipts will pay other transfer and other
 
                                       22
<PAGE>
taxes and governmental charges and such other charges, including a fee for the
withdrawal of shares of Preferred Stock upon surrender of Depositary Receipts,
as are expressly provided in the Deposit Agreement to be for their accounts.
 
    MISCELLANEOUS.  The Depositary will forward to holders of Depositary
Receipts all reports and communications from the Company which are delivered to
the Depositary and which the Company is required to furnish to the holders of
the Preferred Stock.
 
    Neither the Depositary nor the Company will be liable if it is prevented or
delayed by law or any circumstance beyond its control in performing its
obligations under the Deposit Agreement. The obligations of the Company and the
Depositary under the Deposit Agreement will be limited to performance in good
faith of their duties thereunder and they will not be obligated to prosecute or
defend any legal proceeding in respect of any Depositary Shares or Preferred
Stock unless satisfactory indemnity is furnished. They may rely upon written
advice of counsel or accountants, or upon information provided by persons
presenting Preferred Stock for deposit, holders of Depositary Receipts or other
persons believed to be competent and on documents believed to be genuine.
 
    RESIGNATION AND REMOVAL OF DEPOSITARY.  The Depositary may resign at any
time by delivering to the Company notice of its election to do so, and the
Company may at any time remove the Depositary, any such resignation or removal
to take effect upon the appointment of a successor Depositary and its acceptance
of such appointment. Such successor Depositary must be appointed within 60 days
after delivery of the notice of resignation or removal and must be a bank or
trust company having its principal office in the United States and having a
combined capital and surplus of at least $50,000,000.
 
CERTAIN PROVISIONS OF ASHLAND'S RESTATED ARTICLES
 
    In the event of a proposed merger or tender offer, proxy contest or other
attempt to gain control of Ashland not approved by the Board of Directors, it
would be possible, subject to any limitations imposed by applicable law, the
Restated Articles and the applicable rules of the stock exchanges upon which the
Common Stock is listed, for the Board of Directors to authorize the issuance of
one or more series of preferred stock with voting rights or other rights and
preferences which would impede the success of the proposed merger, tender offer,
proxy contest or other attempt to gain control of Ashland. The consent of the
holders of Common Stock would not be required for any such issuance of preferred
stock.
 
    The Restated Articles incorporate in substance certain provisions of the
Kentucky Business Corporation Act to require approval of the holders of at least
80% of Ashland's voting stock, plus two-thirds of the voting stock other than
voting stock owned by a 10% shareholder, as a condition to mergers and certain
other business combinations involving Ashland and such 10% shareholder unless
(a) the transaction is approved by a majority of the continuing directors (as
defined) of Ashland or (b) certain minimum price and procedural requirements are
met. In addition, the Kentucky Business Corporation Act includes a standstill
provision which precludes a business combination from occurring with a 10%
shareholder, notwithstanding any vote of shareholders or price paid, for a
period of five years after the date such 10% shareholder becomes a 10%
shareholder, unless a majority of the independent directors (as defined) of
Ashland approves such combination before the date such shareholder becomes a 10%
shareholder.
 
    The Restated Articles also provide that (i) the Board of Directors is
classified into three classes, (ii) a director may be removed from office
without "cause" (as defined) only by the affirmative vote of the holders of at
least 80% of the voting power of the then outstanding voting stock of Ashland,
(iii) the Board of Directors may adopt By-laws concerning the conduct of, and
matters considered at, meetings of shareholders, including special meetings,
(iv) the By-laws and certain provisions of the Restated Articles may be amended
only by the affirmative vote of the holders of at least 80% of the voting power
 
                                       23
<PAGE>
of the then outstanding voting stock of Ashland and (v) the By-laws may be
adopted or amended by the Board of Directors, subject to amendment or repeal
only by affirmative vote of the holders of at least 80% of the voting power of
the then outstanding voting stock of Ashland.
 
                       DESCRIPTION OF SECURITIES WARRANTS
 
    The Company may issue Securities Warrants for the purchase of Debt
Securities, Preferred Stock or Common Stock. Securities Warrants may be issued
independently or together with Debt Securities, Preferred Stock or Common Stock
offered by any Prospectus Supplement and may be attached to or separate from any
such Offered Securities. Each series of Securities Warrants will be issued under
a separate warrant agreement (a "Securities Warrant Agreement") to be entered
into between the Company and a bank or trust company, as warrant agent (the
"Securities Warrant Agent"), all as set forth in the Prospectus Supplement
relating to the particular issue of Offered Securities Warrants. The Securities
Warrant Agent will act solely as an agent of the Company in connection with the
Securities Warrants and will not assume any obligation or relationship of agency
or trust for or with any holders of Securities Warrants or beneficial owners of
Securities Warrants. The following summary of certain provisions of the
Securities Warrants does not purport to be complete and is subject to, and is
qualified in its entirety by reference to, all the provisions of the Securities
Warrant Agreements.
 
    Reference is made to the Prospectus Supplement relating to the particular
issue of Securities Warrants offered thereby for the terms of such Securities
Warrants, including, where applicable: (i) the designation, aggregate principal
amount, currencies, denominations and terms of the series of Debt Securities
purchasable upon exercise of Securities Warrants to purchase Debt Securities and
the price at which such Debt Securities may be purchased upon such exercise;
(ii) the designation, number of shares, stated value and terms (including,
without limitation, liquidation, dividend, conversion and voting rights) of the
series of Preferred Stock purchasable upon exercise of Securities Warrants to
purchase shares of Preferred Stock and the price at which such number of shares
of Preferred Stock of such series may be purchased upon such exercise; (iii) the
number of shares of Common Stock purchasable upon the exercise of Securities
Warrants to purchase shares of Common Stock and the price at which such number
of shares of Common Stock may be purchased upon such exercise; (iv) the date on
which the right to exercise such Securities Warrants shall commence and the date
on which such right shall expire (the "Expiration Date"); (v) United States
Federal income tax consequences applicable to such Securities Warrants; and (vi)
any other terms of such Securities Warrants. Securities Warrants for the
purchase of Preferred Stock and Common Stock will be offered and exercisable for
U.S. dollars only. Securities Warrants will be issued in registered form only.
The exercise price for Securities Warrants will be subject to adjustment in
accordance with the applicable Prospectus Supplement.
 
    Each Securities Warrant will entitle the holder thereof to purchase such
principal amount of Debt Securities or such number of shares of Preferred Stock
or Common Stock at such exercise price as shall in each case be set forth in, or
calculable from, the Prospectus Supplement relating to the Offered Securities
Warrants, which exercise price may be subject to adjustment upon the occurrence
of certain events as set forth in such Prospectus Supplement. After the close of
business on the Expiration Date (or such later date to which such Expiration
Date may be extended by the Company), unexercised Securities Warrants will
become void. The place or places where, and the manner in which, Securities
Warrants may be exercised shall be specified in the Prospectus Supplement
relating to such Securities Warrants.
 
    Prior to the exercise of any Securities Warrants to purchase Debt
Securities, Preferred Stock or Common Stock, holders of such Securities Warrants
will not have any of the rights of holders of the Debt Securities, Preferred
Stock or Common Stock, as the case may be, purchasable upon such exercise,
including the right to receive payments of principal of, premium, if any, or
interest, if any, on
 
                                       24
<PAGE>
the Debt Securities purchasable upon such exercise or to enforce covenants in
the applicable Indenture, or to receive payments of dividends, if any, on the
Preferred Stock or Common Stock purchasable upon such exercise or to exercise
any applicable right to vote.
 
                              PLAN OF DISTRIBUTION
 
   
    Ashland may sell the Offered Securities in any of three ways: (i) through
underwriters or dealers; (ii) directly to one or a limited number of
institutional purchasers; or (iii) through agents. This Prospectus or an
appropriate Prospectus Supplement (which will be included in a Post-Effective
Amendment to the Registration Statement with respect to the Offered Securities
when required) will set forth the terms of the offering of the Offered
Securities, which will include when applicable the name or names of any
underwriters, dealers or agents, the price of the Offered Securities and the net
proceeds to Ashland from such sale, any underwriting discounts or other items
constituting underwriters' compensation, any discounts or concessions allowed or
reallowed or paid to dealers and any securities exchanges on which the Offered
Securities may be listed.
    
 
    If underwriters are used in the sale, the Offered Securities will be
acquired by the underwriters for their own account and may be resold from time
to time in one or more transactions, including negotiated transactions, at a
fixed public offering price or at varying prices determined at the time of sale.
The Offered Securities may be offered to the public either through underwriting
syndicates represented by managing underwriters or directly by one or more
investment banking firms or others, as designated. Unless otherwise set forth in
the Prospectus Supplement, the obligations of the underwriters to purchase the
Offered Securities will be subject to certain conditions precedent and the
underwriters will be obligated to purchase all the Offered Securities if any are
purchased. Any initial public offering price and any discounts or concessions
allowed or reallowed or paid to dealers may be changed from time to time.
 
    If a dealer is utilized in the sale of any Offered Securities in respect of
which this Prospectus is delivered, Ashland will sell such Offered Securities to
the dealer, as principal. The dealer may then resell such Offered Securities to
the public at varying prices to be determined by such dealer at the time of
resale. The name of the dealer and the terms of the transaction will be set
forth in the Prospectus Supplement.
 
    Offered Securities may be sold directly by Ashland to one or more
institutional purchasers, or through agents at a fixed price or prices, which
may be changed, or at varying prices determined at the time of sale. Unless
otherwise indicated in the Prospectus Supplement, any such agent will be acting
on a best efforts basis for the period of its appointment.
 
   
    If so indicated in the Prospectus Supplement, Ashland will authorize agents,
underwriters or dealers to solicit offers by certain specified institutions to
purchase Offered Securities from Ashland at the public offering price set forth
in the Prospectus Supplement pursuant to delayed delivery contracts providing
for payment and delivery on a specified date in the future. Such contracts will
be subject only to those conditions set forth in the Prospectus Supplement, and
the Prospectus Supplement will set forth the commission payable for solicitation
of such contracts.
    
 
    Underwriters and agents may be entitled under agreements entered into with
Ashland to indemnification by Ashland against certain civil liabilities,
including liabilities under the Securities Act, or to contribution with respect
to payments which the agents or underwriters may be required to make in respect
thereof. Underwriters and agents may be customers of, engage in other
transactions with or perform services for Ashland in the ordinary course of
business.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Sections 271B.8-500 through 580 of the Kentucky Business Corporation Act
contain detailed provisions for indemnification of directors and officers of
Kentucky corporations against judgments, penalties, fines, settlements and
reasonable expenses in connection with litigation. Under Kentucky law, the
provisions of a company's articles and by-laws may govern the indemnification of
officers and directors in lieu of the indemnification provided for by statute.
The Registrant has elected to indemnify its officers and directors pursuant to
its Restated Articles, its By-laws and by contract rather than to have such
indemnification governed by the statutory provisions.
 
    Article X of the Restated Articles permits, but does not require, the
Registrant to indemnify its directors, officers and employees to the fullest
extent permitted by law. The Registrant's By-laws require indemnification of
officers and employees of the Registrant and its subsidiaries under certain
circumstances. The Registrant has entered into indemnification contracts with
each of its directors that require indemnification to the fullest extent
permitted by law, subject to certain exceptions and limitations.
 
    The Registrant has purchased insurance which insures (subject to certain
terms and conditions, exclusions and deductibles) the Registrant against certain
costs which it might be required to pay by way of indemnification to its
directors or officers under its Restated Articles or By-laws, indemnification
agreements or otherwise and protects individual directors and officers from
certain losses for which they might not be indemnified by the Registrant. In
addition, the Registrant has purchased insurance which provides liability
coverage (subject to certain terms and conditions, exclusions and deductibles)
for amounts which the Registrant, or the fiduciaries under its employee benefit
plans, which may include its directors, officers and employees, might be
required to pay as a result of a breach of fiduciary duty.

ITEM 17. UNDERTAKINGS.
 
    The undersigned Registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:
 
           (i) to include any prospectus required by Section 10(a)(3) of the
       Securities Act unless the information required to be included in such
       post-effective amendment is contained in periodic reports filed by the
       Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act
       that are incorporated by reference in the registration statement;
 
           (ii) to reflect in the prospectus any facts or events arising after
       the effective date of the registration statement (or the most recent
       post-effective amendment thereof) which, individually or in the
       aggregate, represent a fundamental change in the information set forth in
       the registration statement unless the information required to be included
       in such post-effective amendment is contained in periodic reports filed
       by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange
       Act that are incorporated by reference in the registration statement; and
 
          (iii) to include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.
 
        (2) For the purpose of determining any liability under the Securities
    Act, each such post-effective amendment shall be deemed to be a new
    registration statement relating to the securities offered therein, and the
    offering of such securities at that time shall be deemed to be the initial
    bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Exchange Act that is incorporated by reference in the registration statement
shall be deemed to be a new registration statement relating to the securities
offered herein, and the offering of such securities at that time shall be deemed
to be the initial bona fide offering thereof.
 
    Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that in the opinion of the Commission such indemnification is
against public policy as expressed in the Securities Act, and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of expenses incurred or
paid by a director, officer or controlling person of the Registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy, as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
    The undersigned Registrant hereby, undertakes that:
 
        (1) For purposes of determining any liability under the Securities Act,
    the information omitted from the form of prospectus filed as part of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
    497(h) under the Securities Act shall be deemed to be part of this
    Registration Statement as of the time it was declared effective.
 
                                      II-3
<PAGE>
        (2) For the purpose of determining any liability under the Securities
    Act, each post-effective amendment that contains a form of prospectus shall
    be deemed to be a new registration statement relating to the securities
    offered therein, and the offering of such securities at that time shall be
    deemed to be the initial bona fide offering thereof.
 
    The undersigned Registrant hereby undertakes to file an application for the
purpose of determining the eligibility of the Trustee to act under subsection
(a) of Section 310 of the Trust Indenture Act in accordance with the rules and
regulations prescribed by the Commission under Section 305(b)(2) of the Trust
Indenture Act.

    Pursuant to the requirements of the Securities Act, the Registrant certifies
that it has reasonable grounds to believe that it meets all the requirements for
filing on Form S-3 and has duly caused this Post-Effective Amendment No. 2 to
the Registration Statement to be signed on its behalf by the undersigned,
thereunto duly authorized in the City of Russell, Commonwealth of Kentucky, on
December 18, 1996.

Ladies and Gentlemen:

      Ashland Inc., a Kentucky corporation (the "Company"), confirms its
agreement with you with respect to the issue and sale by the Company of up to
$220,000,000 aggregate principal amount of its Medium-Term Notes, Series H, Due
Nine Months or More from Date of Issue (the "Notes"). The Notes will have the
interest rates, maturities, redemption provisions and other terms as set forth
in a pricing supplement ("Pricing Supplement") to the Prospectus referred to
below. The Notes will be issued under an Indenture dated as of August 15, 1989,
as amended and restated as of August 15, 1990 (the "Indenture"), between the
Company and Citibank, N.A., as trustee (the "Trustee"). The Notes will be
issued, and the terms thereof established, in accordance with the Indenture and,
in the case of Notes sold pursuant to Section 1(a), the Medium-Term Notes
Administrative Procedures attached hereto as Annex A (the "Procedures"). For the
purposes of this Agreement, the term "Agents" shall refer to any or all of you
(and any other person appointed by the Company in accordance with 


                                      -1-
<PAGE>

Section 1(a)) acting solely in the capacity as agent for the Company pursuant to
Section 1(a) and not as principal, the term "Purchasers" shall refer to any or
all of you acting solely as principal pursuant to Section 1(g) and not as agent,
the term "you" shall refer to you acting in both such capacities or in either
such capacity and the term "Closing Date" shall mean the date of delivery of any
Notes sold hereunder, whether to purchasers solicited by you as agents or to you
as principal. The term "Terms Agreement" is defined in Section 1(g). Other terms
are defined in Section 3.

      1. Appointment of Agent; Solicitation by the Agent of Offers to Purchase;
Sales of Notes to a Purchaser. (a) Subject to the terms and conditions set forth
herein, the Company hereby appoints the Agents to act as its agents for the
purpose of soliciting offers to purchase all or part of the Notes from the
Company upon the terms set forth in the Prospectus, as amended or supplemented
from time to time, and in the Procedures. The Company shall have the right to
appoint additional persons to act as its agents for such purposes upon three
days prior notice to the Agents then acting hereunder so long as any such
additional persons become parties to this Agreement upon the same terms and
conditions as shall then be applicable to such Agents. So long as this Agreement
shall remain in effect with respect to any Agents, the Company shall not,
without the consent of such Agents, solicit offers to purchase Notes otherwise
than through one of such Agents, except as contemplated by Section 1(g) hereof
and except that nothing contained herein shall be construed to prevent the
Company from selling Notes at any time (x) in a firm commitment underwriting
pursuant to an underwriting agreement which does not provide for a continuous
offering of such Notes or (y) directly to investors other than the Purchasers,
and no commission shall be payable to the Agents with respect to any such sales.
The Company also reserves the right to sell Notes through agents other than
pursuant to this Agreement where offers to purchase are received through such
agents on an unsolicited basis. Settlement of such sales will be on
substantially the same terms and conditions as are contained herein, including
commissions.

      (b) On the basis of the representations and warranties set forth herein,
but subject to the terms and conditions set forth herein, each Agent agrees to
use its reasonable efforts, as agent of the Company, to solicit offers to
purchase Notes from the Company upon the terms set forth in the Prospectus, as
amended or supplemented from time to time, and in the Procedures. Subject to the
provisions of Section 1(c) and to the Procedures, offers for the purchase of
Notes may be solicited at such times and in such amounts as each Agent may from
time to time deem advisable.

      (c) The Company reserves the right, in its sole discretion, to suspend
solicitation of offers to purchase Notes from the Company at any time for any
period of time or permanently. Upon receipt of at least one business day's prior
notice from the Company, the Agents forthwith will suspend their solicitation of
offers to purchase Notes from the Company until such time as the Company has
advised the Agents that such 


                                      -2-
<PAGE>

solicitation may be resumed.

      (d) Each Agent will communicate to the Company, orally or in writing, each
offer to purchase Notes from the Company that is received by such Agent as agent
of the Company and that is not rejected by such Agent as provided below. The
Company will have the sole right to accept offers to purchase Notes from the
Company and may reject any such offer, in whole or in part, for any reason. Each
Agent may, without notice to the Company, in its discretion reasonably
exercised, reject any offer to purchase Notes from the Company that is received
by such Agent, in whole or in part, and any such rejection shall not be deemed a
breach of such Agent's agreements contained herein.

      (e) The Company agrees to pay each Agent a commission, on the Closing Date
with respect to each sale of Notes by the Company as a result of a solicitation
made by such Agent, in an amount equal to that percentage specified in Schedule
I hereto of the aggregate principal amount of each Note sold by the Company.
Such commission shall be payable as specified in the Procedures. The commission
rates may be amended from time to time by written agreement of the Company and
the Agents. The Terms Agreement may specify any concessions allowed or reallowed
or paid to dealers.

      (f) Each Agent agrees, with respect to any Note denominated in a currency
other than U.S. dollars, as agent, directly or indirectly, not to solicit offers
to purchase, and as principal under any Terms Agreement or otherwise, directly
or indirectly, not to offer, sell or deliver, such Note in, or to residents of,
the country issuing such currency (or, if such Note is denominated in a
composite currency, in any country issuing a currency comprising a portion of
such composite currency), except as permitted by applicable law.

      (g) Subject to the terms and conditions stated herein, whenever the
Company and you determine that the Company shall sell Notes directly to any or
all of you acting as principal (the "Purchaser"), each such sale of Notes shall
be made in accordance with the terms of this Agreement and any supplemental
agreement relating thereto between the Company and the Purchaser. Each such
supplemental agreement (which shall be substantially in the form of Annex B) is
herein referred to as a "Terms Agreement". The Purchaser's commitment to
purchase Notes pursuant to any Terms Agreement shall be deemed to have been made
on the basis of the representations and warranties of the Company herein
contained and shall be subject to the terms and conditions herein set forth.
Each Terms Agreement shall describe the Notes to be purchased by the Purchaser
pursuant thereto, specify the maturity and principal amount of such Notes, the

amendment or supplement which will correct such statement or omission or effect
such compliance, and supply any supplemented Prospectus to you in such
quantities as you may reasonably request.

Section 6(c) but modified to relate to the last day of the fiscal quarter for
which financial statements of the Company were last filed with the Commission

the Registration Statement or the Prospectus is amended or supplemented solely
to include or incorporate by reference financial information as of and for a
fiscal quarter and you shall have reasonably requested that such a letter be

shall be deemed to be an affirmation that its representations and warranties
contained in this Agreement are true and correct at the time of such acceptance
and a covenant that such representations and warranties will be true and correct
at the time of delivery to the purchaser of the Notes relating to such

      9. Indemnification. (a) The Company will indemnify and hold harmless you
and each person, if any, who controls you within the meaning of Section 15 of
the Securities Act against any and all losses, claims, damages and liabilities,
joint or several (including any investigation, legal and other expenses
reasonably incurred in connection with, and any amount paid in settlement of,
any action, suit or proceeding or any claim asserted), to which they, or any of
them, may become subject under the Securities Act, the Exchange Act or other
Federal or state statutory law or regulation, at common law or otherwise,
insofar as such losses, claims, damages or liabilities arise out of or are based
upon any untrue statement or alleged untrue statement of a material fact
contained in any preliminary prospectus, the Registration Statement or the
Prospectus or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading;
provided that the Company will not be liable to the extent that such loss,
claim, damage or liability arises from the sale of Notes by the Company as a
result of a solicitation by you and is based upon an untrue statement or
omission or alleged untrue statement or omission (i) made in reliance upon and
in conformity with information relating to you furnished in writing to the
Company by you expressly for use in the document or (ii) in a preliminary
prospectus if the Prospectus, as amended or supplemented as of the time of the
confirmation of the sale to such person, corrected the untrue statement or
omission or alleged untrue statement or omission which is the basis of the loss,
claim, damage or liability for which indemnification is sought and a copy of the
Prospectus, as so amended (but excluding any documents incorporated therein by
reference), was not 


                                      -14-
<PAGE>

sent or given to such person at or before the confirmation of the sale to such
person in any case where such delivery is required by the Securities Act, unless
such failure to deliver the Prospectus, as so amended, was a result of
noncompliance by the Company with Section 5(d). This indemnity agreement will be
in addition to any liability that the Company might otherwise have.

      (b) Each of you, severally and not jointly, will indemnify and hold
harmless the Company, each person, if any, who controls the Company within the
meaning of Section 15 of the Securities Act, each director of the Company and
each officer of the Company who signs the Registration Statement to the same
extent as the foregoing indemnity from the Company to each of you, but only
insofar as losses, claims, damages or liabilities arise from the sale of Notes
by the Company to any person as a result of a solicitation by each of you and
are based upon any untrue statement or omission or alleged untrue statement or
omission made in any preliminary prospectus, the Registration Statement or the
Prospectus or any amendment or supplement thereto in reliance upon and in
conformity with information relating to each of you furnished in writing to the
Company by each of you expressly for use in the document. This indemnity
agreement will be in addition to any liability that you might otherwise have.

      (c) Any party that proposes to assert the right to be indemnified under
this Section 9 will, promptly after receipt of notice of commencement of any
action against such party in respect of which a claim is to be made against an
indemnifying party or parties under this Section 9, notify each such
indemnifying party of the commencement of such action, enclosing a copy of all
papers served, but the omission to so notify such indemnifying party will not
relieve it from any liability that it may have to any indemnified party
otherwise than under this Section 9. If any such action is brought against any
indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate in, and, to the
extent that it elects by delivering written notice to the indemnified party
promptly after receiving notice of the commencement of the action from the
indemnified party, jointly with any other indemnifying party similarly notified,
to assume the defense of the action, with counsel who shall be reasonably
satisfactory to the indemnified party, and, after notice from the indemnifying
party to the indemnified party of its election to assume the defense, the
indemnifying party will not be liable to the indemnified party for any legal or
other expenses except as provided below and except for the reasonable costs of
investigation subsequently incurred by the indemnified party in connection with
the defense. The indemnified party will have the right to employ its own counsel
in any such action, but the fees and expenses of such counsel will be at the
expense of such indemnified party unless (1) the employment of counsel by the
indemnified party has been authorized in writing by the indemnifying party, (2)
the indemnified party has reasonably concluded that there may be legal defenses
available to it or other indemnified parties which are different from or in
addition to those available to the indemnifying party (in which case the
indemnifying party will not have the right to direct 


                                      -15-
<PAGE>

the defense of such action on behalf of the indemnified party) or (3) the
indemnifying party has not in fact employed counsel reasonably satisfactory to
such indemnified party to assume the defense of such action within a reasonable
time after receiving notice of the commencement of the action, in each of which
cases the reasonable fees and expenses of such counsel will be at the expense of
the indemnifying party or parties and all such fees and expenses will be
reimbursed promptly as they are incurred. An indemnifying party will not be
liable for any settlement of any action or claim effected without its written
consent or, in connection with any proceeding or related proceedings in the same
jurisdiction, for the fees and expenses of more than one separate counsel for
all indemnified parties.

      10. Contribution. In order to provide for just and equitable contribution
in circumstances in which the indemnification provided for in Section 9 is
applicable in accordance with its terms but for any reason is held by a tribunal
to be unavailable from the Company or you, the Company and you will contribute
to the aggregate losses, claims, damages and liabilities (including any
investigation, legal and other expenses reasonably incurred in connection with,
and any amount paid in settlement of, any action or any claims asserted, but
after deducting any contribution received by the Company from persons other than
you, such as persons who control the Company within the meaning of the
Securities Act, officers of the Company who signed the Registration Statement
and directors of the Company, who may also be liable for contribution) to which
the Company and you may be subject in such proportion so that you are
responsible for that portion represented by the percentage that the aggregate
commissions received by you pursuant to Section 1 bears to the aggregate
principal amount of Notes sold by the Company and the Company is responsible for
the balance; provided that (i) you will not be responsible for any amount in
excess of the aggregate commissions received by you pursuant to Section 1 and
(ii) no person found guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any person who was not guilty of such fraudulent misrepresentation. For purposes
of this Section 10, any person who controls a party to this Agreement within the
meaning of the Securities Act will have the same rights to contribution as that
party, and each officer of the Company who signed the Registration Statement and
each director of the Company will have the same rights to contribution as the
Company, subject in each case to clauses (i) and (ii) of this Section 10. Any
party entitled to contribution will, promptly after receipt of notice of
commencement of any action against such party in respect of which a claim for
contribution may be made under this Section 10, notify such party or parties
from whom contribution may be sought, but the omission so to notify will not
relieve the party or parties from whom contribution may be sought from any other
obligation it or they may have otherwise than under this Section 10. No party
will be liable for contribution with respect to any action or claim settled
without its written consent.

      11. Termination. (a) Upon three days written notice, this Agreement may be


                                      -16-
<PAGE>

terminated for any reason at any time by the Company as to any or all of you, or
may be terminated for any reason at any time by any or all of you as to those of
you giving such notice. In the event of any such termination, no party giving
such notice shall have any liability to the other party or parties hereto,
except as provided in Sections 1(e), 5(h), 9, 10 and 12.

      (b) Each Terms Agreement shall be subject to termination in the absolute
discretion of the Purchaser, by notice given to the Company prior to delivery of
any payment for Notes to be purchased thereunder, if prior to such time (1)
trading in any securities of the Company is suspended by the Commission, by an
exchange that lists such securities of the Company, or by the National
Association of Securities Dealers Automated Quotation National Market System,
(2) additional material governmental restrictions, not in force on the date of
this Agreement, have been imposed upon trading in securities generally or
minimum or maximum prices have been generally established on the New York Stock
Exchange or on the American Stock Exchange, or trading in securities generally
has been suspended on any such Exchange or a general banking moratorium has been
established by Federal or New York authorities, or (3) any outbreak or material
escalation of hostilities or other calamity or crisis occurs the effect of which
is such as to make it impracticable to market such Notes.

      12. Miscellaneous. The reimbursement, indemnification and contribution
agreements in Sections 1(e), 5(h), 9, 10 and 11 and the representations and
agreements of the Company and you in this Agreement will remain in full force
and effect until the sixth anniversary of the date of termination of this
Agreement as to any party regardless of any termination of this Agreement or any
investigation made by or on behalf of you, the Company or any controlling person
and will survive delivery of and payment for the Notes.

      This Agreement is for the benefit of you and the Company and their
respective successors and, to the extent expressed in this Agreement, for the
benefit of persons controlling you or the Company, and directors and officers of
the Company, and their respective successors, and no other person, partnership,
association or corporation shall acquire or have any right under or by virtue of
this Agreement.

                  Medium-Term Note Administrative Procedures
                              December 11, 1996

      The Medium-Term Notes, Series H, due Nine Months or More from their issue
date (the "Notes") are to be offered on a continuing basis by Ashland Inc. (the
"Company"). CS First Boston Corporation, Salomon Brothers Inc and Citicorp
Securities, Inc., as agents (individually, an "Agent" and collectively, the
"Agents"), have each agreed to use reasonable efforts to solicit offers to
purchase the Notes. None of the Agents will be obligated to purchase Notes for
their own accounts. The Notes are being sold pursuant to a Distribution
Agreement, dated December 11, 1996 (the "Distribution Agreement"), among the
Company and the Agents, and will be issued pursuant to an Indenture, dated as of
August 15, 1989, as amended and restated as of August 15, 1990 (the
"Indenture"), between the Company and Citibank, N.A., as trustee (the
"Trustee"). The Notes will rank equally with all other unsecured and
unsubordinated indebtedness of the Company and will have been registered with
the Securities and Exchange Commission (the "Commission"). The Notes may be
denominated in U.S. dollars, or in such foreign currencies or currency units as
may be designated by the Company. The Notes are to be offered in an aggregate
principal amount of up to U.S.u$220,000,000 (or the equivalent thereof if any of
the Notes is denominated in foreign currency or currency units).

      Administrative and record-keeping responsibilities will be handled for the
Company by its Treasury and Finance Department. The Company will advise the
Agents in writing of those persons handling administrative responsibilities with
whom the Agents are to communicate regarding offers to purchase Notes and the
details of their delivery. Administrative procedures and certain terms of the
offering are explained below. Capitalized terms used herein and not otherwise
defined herein shall have the meanings assigned thereto in the Distribution
Agreement, the Prospectus or the Indenture.

                          Certain Terms of the Offering

      Notes will be issued only in fully registered form and will be represented
by either a global certificate (a "Global Certificate") delivered to Citibank,
N.A., as custodian for The Depository Trust Company (the "Depositary"), with
ownership of beneficial interests in such Global Certificates recorded in the
book-entry system maintained by the Depositary (a "Book-Entry Note") or a
certificate (a "Definitive Certificate") delivered to a person designated by an
Agent.

      Citibank, N.A., in addition to acting as Trustee, will act as Exchange
Rate Agent, Paying Agent, Calculation Agent and Security Registrar for the
Company, in each case, 


                                      -1-
<PAGE>

under the Indenture (in any of the foregoing capacities, as applicable,
"Citibank").

      Part I contains provisions common to Book-Entry and Certificated Notes.
Part II contains provisions specific to Certificated Notes and Part III contains
provisions specific to Book-Entry Notes. To the extent the procedures set forth
below conflict with the provisions of the Notes, the Indenture or the
Distribution Agreement, the terms and provisions of the Notes, the Indenture and
the Distribution Agreement shall prevail. Unless otherwise defined herein, terms
defined in the Indenture or the Notes shall be used herein as therein defined.

                               PART I: GENERAL

Price to Public

      Each Note will be issued at or above par.

Denominations

      The minimum denomination of the Notes will be $1,000 and in denominations
of integral multiples of $1,000 in excess thereof.

Issue Date

      Each Note will be dated the date of its authentication. Each Note will
also bear an original issue date (the "Issue Date") which, with respect to any
Note (or portion thereof), shall mean the date of its original issuance and
shall be specified therein. The Issue Date shall remain the same for all Notes
subsequently issued upon transfer, exchange or substitution of a Note,
regardless of their dates of authentication.

Maturities

      Each Note will mature on a Business Day, selected by the purchaser and
agreed to by the Company, which will be at least nine months after the Issue
Date. Each Floating Rate Note (as defined below) will mature on an Interest
Payment Date (as defined below) for such Note.

Interest Payment

      Each interest bearing Note will bear interest from and including its Issue
Date, or in the case of Notes issued upon transfer or exchange, from the most
recent Interest Payment Date to which interest has been paid or provided for, to
but excluding the relevant Interest Payment Date or the maturity date of such
Note. Interest payments, if any, will be the amount of interest accrued from and
including the next preceding Interest Payment Date in respect of which interest
has been paid or duly provided for, or from and including the date of issue, if
no interest has been paid with respect to such Note, to but excluding the
applicable Interest Payment Date. However, in the case of Floating Rate Notes on
which the interest rate is reset daily or weekly, the interest 


                                      -2-
<PAGE>

payments (other than payments on any date on which principal 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, through and including the Regular Record Date next
preceding the applicable Interest Payment Date, except that interest paid at
Maturity will include interest accrued to but excluding such date. Each Note
will bear interest (i) in the case of Notes bearing interest at a Fixed Rate
(the "Fixed Rate Notes"), at the annual rate stated on the face thereof, payable
semi-annually in arrears on February 15 and August 15 unless otherwise specified
in the related pricing supplement to the Prospectus Supplement (the "Pricing
Supplement") (each an "Interest Payment Date" with respect to such Fixed Rate
Note) and at maturity and (ii) in the case of Notes bearing interest at a rate
or rates determined by reference to an interest rate formula (the "Floating Rate
Notes"), at a rate determined pursuant to the formula stated on the face
thereof, payable in arrears on such dates as are specified therein and in the
Pricing Supplement (each such date an "Interest Payment Date" with respect to
such Floating Rate Note). In addition, a Floating Rate Note may bear interest at
the lowest or highest or average of two or more interest rate formulae. Interest
(including payments for partial periods) will be calculated and paid (a) in the
case of Fixed Rate Notes, on the basis of a 360-day year of twelve 30-day
months, (b) in the case of Floating Rate Notes whose interest formula is based
on the Treasury Rate or the Prime Rate, on the basis of the actual number of
days in the year divided by 365 or 366, as the case may be, and (c) in the case
of Floating Rate Notes whose interest formula is based on the Commercial Paper
Rate, the LIBOR Rate, the Federal Funds Rate, or on the CD Rate, on the basis of
the actual number of days in the year divided by 360. Interest will be payable
(a) in the case of Fixed Rate Notes, to the person in whose name the Note is
registered at the close of business on the February 1 or August 1 (the Regular
Record Dates with respect to Fixed Rate Notes) next preceding the Interest
Payment Date, unless otherwise specified in the Pricing Supplement, and (b) in
the case of Floating Rate Notes, to the person in whose name the Note is
registered at the close of business on the dates established on the Issue Date
and set forth in each such Note and in the applicable Pricing Supplement (the
Regular Record Dates with respect to Floating Rate Notes); provided, however,
that interest payable on a maturity date will be payable to the person to whom
principal shall be payable. Unless otherwise set forth in the applicable
Prospectus Supplement, the first payment of interest on any Note originally
issued between a Regular Record Date and an Interest Payment Date will be made
on the Interest Payment Date following the next succeeding Regular Record Date.
With respect to Fixed Rate Notes, each payment of interest shall include
interest accrued to but excluding the date of such payment. For special
provisions relating to Floating Rate Notes, see the section entitled
"Description of the Medium-Term Notes" in the Prospectus Supplement relating to
the Notes, dated Decemberu11, 1996, attached hereto and hereinafter referred to
as the "Prospectus Supplement". Except in the case of Book-Entry Notes, all
interest payments (excluding interest payments made at maturity) will be made by
check mailed to the person entitled thereto as provided above. All interest
payments on any Book-Entry Note will be made to the Depositary, or its nominee,
as Noteholder thereof, in accordance with arrangements then in effect between
the Trustee and the Depositary.

Trustee and Citibank Not to Risk Funds


                                      -3-
<PAGE>

      Nothing herein shall be deemed to require the Trustee or Citibank to risk
or expend its own funds in connection with any payment to the Company, or the
Agents, or the Depositary, or any Noteholder, it being understood by all parties
that payments made by the Trustee or Citibank to either the Company, or the
Agents, or the Depositary, or any Noteholder shall be made only to the extent
that funds are provided to the Trustee for such purpose.

Advertising Costs

      The Company will determine with the Agents the amount of advertising that
may be appropriate in offering the Notes. Advertising expenses approved in
advance by the Company will be paid by the Company.

Business 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, the unit of account from time to
time 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.

Procedures for Establishing the Terms of the Notes

      The Company and the Agents will discuss from time to time the Issue Date,
maturity date, interest rates, and other provisions of the Notes that may be
sold as a result of the solicitation of offers by the Agents. If the Company
decides to post rates and a decision has been reached to change interest rates,
the Company will promptly notify each Agent. Each Agent will forthwith suspend
solicitation of purchases. At that time, the Agents will recommend and the
Company will establish rates to be so "posted". Following establishment of
posted rates and prior to the filing or mailing described in the following
sentence, the Agents may only record indications of interest in purchasing Notes
at the posted rates. If the Company accepts an offer at the posted rates, it
will prepare a Pricing Supplement reflecting the terms of such offer and will
arrange to have such Pricing Supplement electronically filed with the Commission
in accordance with the applicable paragraph of Rule 424(b) under the Act and
Rule 101(a) of Regulation S-T, and will supply at least 10 copies of the Pricing
Supplement to the Agent who presented such offer (the "Presenting Agent"). No
settlements may occur prior to such mailing or filing and the Agents will not,
prior to such mailing or filing, mail confirmations to customers who have
offered to purchase Notes at the posted rates. The Company will not offer Notes
denominated in a foreign currency unless it has 


                                      -4-
<PAGE>

received confirmation from the Trustee that the Trustee will be able to perform
its duties in respect of such Notes, and that the Trustee has had sufficient
time to make the necessary arrangements.

      Outdated Pricing Supplements and copies of the Prospectus to which they
are attached (other than those retained for files) will be destroyed.

Suspension of Solicitation; Amendment or Supplement

      As provided in the Distribution Agreement, the Company may suspend
solicitation of purchases at any time and, upon receipt of at least one Business
Day's prior notice from the Company, the Agents will each forthwith suspend
solicitation until such time as the Company has advised them that solicitation
of purchases may be resumed.

      If the Agents receive the notice from the Company contemplated by Section
5(b) of the Distribution Agreement, they will promptly suspend solicitation and
will only resume solicitation as provided in the Distribution Agreement. If the
Company decides to amend or supplement the Registration Statement or the
Prospectus relating to the Notes, it will promptly advise each Agent and will
furnish each Agent with the proposed amendment or supplement in accordance with
the terms of the Distribution Agreement. The Company will promptly file or mail
to the Commission for filing such amendment or supplement, provide the Agents
with copies of any such amendment or supplement, confirm to the Agents that such
amendment or supplement has been filed with the Commission and advise the Agents
that solicitation may be resumed.

      Any such suspension shall not affect the Company's obligations under the
Distribution Agreement; and in the event that at the time the Company suspends
solicitation of purchases there shall be any offers already accepted by the
Company outstanding for settlement, the Company will have the sole
responsibility for fulfilling such obligations. The Company will in addition
promptly advise the Agents and the Trustee if such offers are not to be settled
and if copies of the Prospectus as in effect at the time of the suspension may
not be delivered in connection with the settlement of such offers.

Acceptance of Offers

      Each Agent will promptly advise the Company, orally or in writing, of each
reasonable offer to purchase Notes received by it, other than those rejected by
such Agent. Each Agent may, in its discretion reasonably exercised, without
notice to the Company, reject any offer received by it, in whole or in part. The
Company will have the sole right to accept offers to purchase Notes and may
reject any such offer, in whole or in part. If the Company rejects an offer, the
Company will promptly notify the Agent involved.

Delivery of Prospectus

      A copy of the Prospectus as most recently amended or supplemented on the


                                      -5-
<PAGE>

date of delivery thereof (except as provided below) must be delivered to a
purchaser prior to or together with the earlier of the delivery of (i) the
written confirmation provided for above, and (ii) any Note purchased by such
purchaser. The Company shall ensure that the Presenting Agent receives copies of
the Prospectus and each amendment or supplement thereto (including appropriate
pricing supplements) in such quantities and within such time limits as will
enable the Presenting Agent to deliver such confirmation or Note to a purchaser
as contemplated by these procedures and in compliance with the preceding
sentence. If, since the date of acceptance of a purchaser's offer, the
Prospectus shall have been supplemented solely to reflect any sale of Notes on
terms different from those agreed to between the Company and such purchaser or a
change in posted rates not applicable to such purchaser, such purchaser shall
not receive the Prospectus as supplemented by such new supplement, but shall
receive the Prospectus as supplemented to reflect the terms of the Notes being
purchased by such purchaser and otherwise as most recently amended or
supplemented on the date of delivery of the Prospectus.

Determination of Settlement Date

      All offers accepted by the Company will be settled no later than the third
Business Day next succeeding the date of acceptance unless otherwise agreed by
any purchaser and the Company. The settlement date shall be specified upon
receipt of an offer.

                         PART II: CERTIFICATED NOTES

Settlement Date

      The Company will instruct, by telecopy or other acceptable means, the
Trustee to authenticate and deliver the Notes no later than 2:15 P.M., New York
City time, on the settlement date. Such instructions will be given by the
Company no later than 3:00 P.M., New York City time, on the Business Day prior
to the settlement date unless the settlement date is the date of acceptance by
the Company of the offer to purchase the Notes, in which case such instructions
will be given by the Company by 10:00 A.M., New York City time.

Details for Settlement

      For each offer accepted by the Company, the Presenting Agent shall
communicate to the Company's Treasury and Finance Department by telephone,
facsimile transmission or other acceptable means the following information (the
"Purchase Information"):

      1.    Exact name in which the Note or Notes are to be registered
            ("registered owner").

      2.    Exact address of registered owner and, if different, the address for
            payment of principal and interest.


                                      -6-

      3.    Taxpayer identification number of registered owner.

      4.    Principal amount of each Note in authorized denominations to be
            delivered to registered owner.

      5.    Currency or currency unit of such principal amount.

      6.    The issue price, interest rate, if fixed or, if floating, the
            initial interest rate, the interest rate basis, the spread or spread
            multiplier, the maximum or minimum interest rates, if any, the index
            maturity, the Interest Reset Dates and the Interest Payment Dates
            (as such terms are defined in the Prospectus Supplement) of each
            Note, and all other items necessary to complete each Note.

      8.    Issue date.

      9.    Settlement date.

            settlement).

      11.   Terms of redemption and Redemption Date, if any.

      12.   Net proceeds to the Company.

      The Issue Date of, and the settlement date for, Notes will be the same.
Before accepting any offer to purchase Notes to be settled in less than three
Business Days, the Company shall verify that the Trustee will have adequate time
to prepare and authenticate the Notes.

      After receiving the details for each offer from the Presenting Agent, the
Company will, after recording the details and any necessary calculations,
communicate the Purchase Information by facsimile transmission or other
acceptable means, to the Trustee. The Company will identify in writing to the
Trustee officers of the Company who are authorized to provide such details for
each such offer to the Trustee.

Settlement; Note Deliveries and Cash Payment

      Upon the receipt of appropriate documentation and instructions from the
Company, the Trustee will cause the Notes to be prepared and authenticated.

      The Trustee will deliver the Notes, in accordance with instructions from
the Company, to the Presenting Agent, as the Company's agent, for the benefit of
the purchaser. The Presenting Agent shall make payment in immediately available
funds directly to the account of the Company in an amount equal to the face
amount of the Notes.


                                      -7-
<PAGE>

      The Presenting Agent, as the Company's agent, will deliver the Notes (with
the written confirmation provided for above) to the purchaser thereof against
payment by such purchaser in immediately available funds. Delivery of any
confirmation or Note will be made in compliance with "Delivery of Prospectus"
above.

Fails

      In the event that a purchaser shall fail to accept delivery of and make
payment for a Note on the settlement date, the Presenting Agent will notify the
Trustee and the Company, by telephone or other acceptable means. If the Note has
been delivered to the Presenting Agent, as the Company's agent, the Presenting
Agent shall return such Note to the Trustee. If funds have been advanced for the
purchase of such Note, the Trustee will, immediately upon receipt of such Note,
confirm receipt to the Company and the Company shall refund the payment
previously made by the Presenting Agent in immediately available funds. Such
payments will be made on the settlement date, if possible, and in any event not
later than the Business Day following the settlement date. If such fail shall
have occurred for any reason other than the failure of the Presenting Agent to
provide the Purchase Information to the Company or to provide a confirmation to
the purchaser, the Company will reimburse the Presenting Agent on an equitable
basis for its loss of the use of funds during the period when they were credited
to the account of the Company.

      Immediately upon receipt of the Note in respect of which the fail
occurred, the Trustee will cause the Security Registrar to make appropriate
entries to reflect the fact that the Note was never issued and will destroy the
Note.

Payment of Interest

      On the fifth Business Day immediately preceding each Interest Payment
Date, the Trustee will furnish the Company with the total amount of the interest
payments to be paid on the Certificated Notes on such Interest Payment Date. The
Trustee will provide monthly to the Company's Treasury and Finance Department a
list of the principal and interest to be paid on Certificated Notes maturing in
the next succeeding month, to the extent then known. The Trustee will assume
responsibility for withholding taxes on interest paid as required by law.

Maturity

      Upon presentation of each Certificated Note at maturity the Trustee (or
any duly appointed Paying Agent) will pay the principal amount thereof, together
with accrued interest due at maturity out of immediately available funds
provided by the Company. Such payment shall be made in immediately available
funds to the holder of the Note, provided that the Note is presented to the
Trustee (or any such Paying Agent) in time for the Trustee (or such Paying
Agent) to make payments in such funds in accordance with its normal procedures.
The Company will provide the Trustee (and any such Paying Agent) with funds
available for immediate use for such purpose. Notes presented at maturity will
be cancelled by the Trustee as provided in the Indenture.


                                      -8-
<PAGE>

Authenticity of Signatures

      The Company will cause the Trustee to furnish the Agents from time to time
with the specimen signatures of each of the Trustee's officers, employees or
agents who have been authorized by the Trustee to authenticate Notes, but the
Agents will have no obligation or liability to the Company or the Trustee in
respect of the authenticity of the signature of any officer, employee or agent
of the Company or the Trustee on any Note.

                          PART III: BOOK-ENTRY NOTES

      An owner of a Book-Entry Note will not be entitled to receive a
certificate representing such Note. In connection with the qualification of the
Book-Entry Notes for eligibility in the book-entry system maintained by the
Depositary, Citibank will perform the custodial, document control and
administrative functions described below, in accordance with its respective
obligations under a Letter of Representations (the "Letter of Representations")
from the Company and Citibank to the Depositary and a Medium-Term Note
Certificate Agreement (the "Certificate Agreement") between Citibank and the
Depositary, and its obligations as a participant in the Depositary, including
the Depositary's Same-Day Funds Settlement system ("SDFS").

Issuance

      On any date of settlement (as defined under "settlement" below) for one or
more Book-Entry Notes, the Company will issue a Global Certificate or
Certificates in fully registered form without coupons representing in each case
not in excess of $200,000,000 principal amount of all of such Book-Entry Notes
that have the same interest rate, Stated Maturity and terms. Each Global
Certificate will be dated and issued as of the date of its authentication by
Citibank as Trustee. No Global Certificate will represent any Certificated Note.

Identification Numbers

      The Company will arrange, on or prior to the commencement of a program for
the offering of Book-Entry Notes, with the CUSIP Service Bureau of Standard &
Poor's (the "CUSIP Service Bureau") for the reservation of a series of CUSIP
numbers (including tranche numbers), consisting of approximately 900 CUSIP
numbers relating to Global Certificates representing the Book-Entry Notes. The
Company will obtain from the CUSIP Service Bureau a written list of such series
of reserved CUSIP numbers and will deliver such list to Citibank and the
Depositary. Citibank will assign CUSIP numbers to Global Certificates as
described below under Settlement Procedure "B". The Depositary will notify the
CUSIP Service Bureau periodically of the CUSIP numbers that the Company has
assigned to Global Certificates. Citibank will notify the Company at any time
when fewer than 100 of the reserved CUSIP numbers remain unassigned to Global
Certificates, and if it deems it necessary, the Company will reserve additional
CUSIP numbers for assignment to Global Certificates representing Book-Entry
Notes. Upon obtaining such additional CUSIP numbers, the Company shall deliver a
list thereof to Citibank and the Depositary.


                                      -9-
<PAGE>

Registration

      Each Global Certificate will be registered in the name of Cede & Co., as
nominee for the Depositary, on the Securities Register maintained under the
Indenture governing such Global Certificate. The beneficial owner of a
Book-Entry Note (or one or more indirect participants in the Depositary
designated by such owner) will designate one or more participants in the
Depositary (with respect to such Note, the "Participants") to act as agent or
agents for such owner in connection with the book-entry system maintained by the
Depositary, and the Depositary will record in book-entry form, in accordance
with instructions provided by such Participants, a credit balance with respect
to such Note in the account of such Participants. The ownership interest of such
beneficial owner in such Note will be recorded through the records of such
Participants or through the separate records of such Participants and one or
more indirect participants in the Depositary. So long as Cede & Co. is the
registered owner of a Global Certificate, the Depositary will be considered the
sole owner and holder of the Book-Entry Notes represented by such Global
Certificate for all purposes under the Indenture.


                                      -10-
<PAGE>

Transfers

      Transfers of a Book-Entry Note will be accomplished by book entries made
by the Depositary and, in turn, by Participants (and in certain cases, one or
more indirect participants in the Depositary) acting on behalf of beneficial
transferors and transferees of such Note.

Consolidation and Exchange

      Citibank may deliver to the Depositary and the CUSIP Service Bureau at any
time a written notice of consolidation specifying (i) the CUSIP numbers of two
or more Outstanding Global Certificates that represent Book-Entry Notes having
the same interest rate, Stated Maturity and tenor and for which interest has
been paid to the same date, (ii) a date, occurring at least thirty days after
such written notice is delivered and at least thirty days before the next
Interest Payment Date for such Book-Entry Notes, on which such Global
Certificates shall be exchanged for a single replacement Global Certificate and
(iii) a new CUSIP number, obtained from the Company, to be assigned to such
replacement Global Certificate. Upon receipt of such a notice, the Depositary
will send to its participants (including Citibank) a written reorganization
notice to the effect that such exchange will occur on such date. Prior to the
specified exchange date, Citibank will deliver to the CUSIP Service Bureau a
written notice setting forth such exchange date and the new CUSIP number and
stating that, as of such exchange date, the CUSIP numbers of the Global
Certificates to be exchanged will no longer be valid. On the specified exchange
date, Citibank will exchange such Global Certificates for a single Global
Certificate bearing the new CUSIP number and new Issue Date, which shall be the
most recent Interest Payment Date to which interest has been paid or duly
provided for on the predecessor Global Certificates, and the CUSIP numbers of
the exchanged Global Certificates will, in accordance with CUSIP Service Bureau
procedures, be canceled and not immediately reassigned. Notwithstanding the
foregoing, if the Global Certificates to be exchanged exceed $200,000,000 in
aggregate principal amount, one Global Certificate will be authenticated and
issued to represent each $200,000,000 of principal amount of the exchanged
Global Certificates and an additional Global Certificate will be authenticated
and issued to represent any remaining principal amount of such Global
Certificates (see "Denominations" below).

Denominations

      Book-Entry Notes will be issued in principal amounts of $1,000 or any
amount in excess thereof that is an integral multiple of $1,000. Global
Certificates will be denominated in principal amounts not in excess of
$200,000,000. If one or more Book-Entry Notes having an aggregate principal
amount in excess of $200,000,000 would, but for the preceding sentence, be
represented by a single Global Certificate, then one Global Certificate will be
issued to represent $200,000,000 principal amount of such Book-Entry Note or
Notes and an additional Global Certificate will be issued to represent any
remaining principal amount of such Book-Entry Note or Notes. In such a case,
each of the Global Certificates representing such Book-Entry Note or Notes shall
be assigned the same CUSIP number.


                                      -11-
<PAGE>

Interest

      Standard & Poor's will use the information received in the pending deposit
message described under Settlement Procedure "C" below in order to include the
amount of any interest payable and certain other information regarding the
related Global Security in the appropriate weekly bond report published by
Standard & Poor's.

Payments of Principal and Interest

      Payments of Interest Only. Promptly after each Regular Record Date,
Citibank will deliver to the Company and the Depositary a written notice
specifying by CUSIP number the amount of interest to be paid on each Global

Payment Date coinciding with Maturity) and the total of such amounts. The
Depositary will confirm the amount payable on each Global Certificate on such
Interest Payment Date by reference to the daily bond reports published by
Standard & Poor's. The Company will pay to Citibank, as Paying Agent, the total
amount of interest due on such Interest Payment Date (other than at Maturity),
and Citibank will pay such amount to the Depositary at the times and in the
manner set forth below under "Manner of Payment".

      Payments at Maturity. On or about the first Business Day of each month,
Citibank will deliver to the Company, the Depositary and the Trustee a written
list of principal and interest to be paid on each Global Certificate maturing in
the following month. The Company, Citibank and the Depositary will confirm the
amounts of such principal and interest payments with respect to each such Global
Certificate on or about the fifth Business Day preceding the Maturity of such
Global Certificate. The Company will pay to Citibank as the Paying Agent, the
principal amount of such Global Certificate, together with interest due at such
Maturity and Citibank will pay such amount to the Depositary at the times and in
the manner set forth below under "Manner of Payment".

      Promptly after payment to the Depositary of the principal and interest due
at the Maturity of such Global Certificate, Citibank will cancel such Global
Certificate and deliver it to the Company. Citibank will from time to time, on
request by the Trustee, deliver to the Trustee a written statement indicating
the total principal amount of outstanding Global Certificates for which it
serves as Trustee as of the immediately preceding Business Day.

      Manner of Payment. The total amount of any principal and/or interest due
on Global Certificates on any Interest Payment Date or at Maturity shall be paid
by the Company to Citibank in funds available for use by Citibank as of 9:30
A.M. (New York City time) on such date. The Company will make such payment on
such Global Certificates by instructing Citibank to withdraw funds from an
account maintained by the Company at Citibank, N.A. The Company will confirm
such instruction in writing to Citibank. Citibank will forward to the Company an
appropriate debit advice. Prior to


                                      -12-
<PAGE>

10:00 A.M. (New York City time) on such date or as soon as possible thereafter,
Citibank will make such payments to the Depositary in same day funds in
accordance with the payment provisions contained in the Letter of
Representations. The Depositary will allocate such payments to its Participants
in accordance with its existing operating procedures. NONE OF THE COMPANY, THE
TRUSTEE NOR CITIBANK SHALL HAVE ANY RESPONSIBILITY OR LIABILITY FOR THE PAYMENT
BY THE DEPOSITARY TO SUCH PARTICIPANTS OF THE PRINCIPAL OF AND INTEREST ON THE
BOOK-ENTRY NOTES.

      Withholding Taxes. The amount of any taxes required under applicable law
to be withheld from any interest payment on a Book-Entry Note will be determined
and withheld by the Participant, indirect participant in the Depositary or other
Person responsible for forwarding payments and materials directly to the
beneficial owner of such Note.

Settlement

      The receipt by the Company of immediately available funds in payment for a
Book-Entry Note and the authentication and issuance of the Global Certificate
representing such Note shall constitute "settlement" with respect to such
Book-Entry Note. All orders accepted by the Company will be settled on the next
Business Day pursuant to the timetable for settlement set forth below unless the
Company and the purchaser agree to settlement on a later date.

Settlement Procedures Timetable

      For orders of Book-Entry Notes solicited by an Agent, as agent, and
accepted by the Company for settlement on the first Business Day after the sale
date, Settlement Procedures "A" through "L" set forth above shall be completed
as soon as possible but not later than the respective times (New York City time)
set forth below:

            Settlement
            Procedure               Time
            ---------               ----

            A-B                     11:00 A.M. on the sale date
            C                       2:00 P.M. on the sale date
            D                       3:00 P.M. on day before settlement date
            E                       9:00 A.M. on settlement date
            F                       10:00 A.M. on settlement date
            G-H                     2:00 P.M. on settlement date
            I                       4:45 P.M. on settlement date
            J-L                     5:00 P.M. on settlement date


                                      -15-
<PAGE>

      If a sale is to be settled more than one Business Day after the sale date,
Settlement Procedures "A", "B" and "C" shall be completed as soon as practicable
but no later than 11:00 A.M. and 2:00 P.M., as the case may be, on the first
Business Day after the sale date. In connection with a sale which is to be
settled more than one Business Day after the sale date, if the initial interest
rate for a Floating Rate Note is not known at the time that Settlement Procedure
"A" is completed, Settlement Procedures "B" and "C" shall be completed as soon
as such rates have been determined, but no later than 11:00 a.m. and 2:00 p.m.,
respectively, on the second Business Day before the Settlement Date. Settlement
Procedure "I" is subject to extension in accordance with any extension of
Fedwire closing deadlines and in the other events specified in the SDFS
operating procedures in effect on the settlement date.

      If settlement of a Note is rescheduled or cancelled, Citibank will deliver
to the Depositary, through the Depositary's Participant Terminal System, a
cancellation message to such effect by no later than 2:00 p.m. on the Business
Day immediately preceding the scheduled settlement date.

Failure to Settle

      Prior to Citibank's entry of an SDFS deliver order with respect to a
Book-Entry Note pursuant to Settlement Procedure "G", Citibank, upon written
request of the Company, shall deliver through the Depositary's Participant
Terminal System, as soon as practicable, but not later than 2:00 p.m. on any
Business Day, a withdrawal message instructing the Depositary to debit such
Book-Entry Note to Citibank's participant account. The Depositary will process
the withdrawal message, provided that Citibank's participant account contains a
principal amount of the Global Certificate representing such Book-Entry Note
that is at least equal to the principal amount to be debited. If a withdrawal
message is processed with respect to all the Book-Entry Notes represented by a
Global Certificate, Citibank will mark such Global Certificate "Cancelled", make
appropriate entries in Citibank's records and send such cancelled Global
Certificate to the Company. The CUSIP number assigned to such Global Certificate
shall, in accordance with CUSIP Service Bureau procedures, be cancelled and not
immediately reassigned. If a withdrawal message is processed with respect to one
or more, but not all, of the Book-Entry Notes represented by a Global
Certificate, Citibank will exchange such Global Certificate for two Global
Certificates, one of which shall represent such Book-Entry Note or Notes and
shall be cancelled immediately after issuance and the other of which shall
represent the other Book-Entry Notes previously represented by the surrendered
Global Certificate and shall bear the CUSIP number of the surrendered Global
Certificate.

      If the purchase price for any Book-Entry Note is not timely paid to the
Participant with respect to such Note by the beneficial purchaser thereof (or a
Person, including an indirect participant in the Depositary, acting on behalf of
such purchaser), such Participant and, in turn, the Agent for such Note may
enter a deliver order through the Depositary's Participant Terminal System
debiting such Note to such Agent's participant account and crediting such Note
free to the participant account of Citibank and shall notify Citibank and the
Company thereof. Thereafter, Citibank (i) will immediately notify the Company
thereof, once Citibank has confirmed that such Note has been credited to 


                                      -16-
<PAGE>

its participant account, and the Company shall immediately transfer by Fedwire
(in immediately available funds) to such Agent an amount equal to the price of
such Note which was previously transferred to the account of the Company
maintained at Citibank, N.A. in accordance with Settlement Procedure and (ii)
Citibank will deliver the withdrawal message and take the related actions
described in the preceding paragraph. The Agent will not be entitled to any
commission with respect to any Note which the purchaser does not accept and make
payment for. Such debits and credits will be made on the Settlement Date, if
possible, and in any event not later than 5:00 p.m. on the following Business
Day. If such failure shall have occurred for any reason other than failure by
the applicable Agent to perform its obligations hereunder or under the
Distribution Agreement, the Company will reimburse such Agent on an equitable
basis for its loss of the use of funds during the period when the funds were
credited to the account of the Company.

      Notwithstanding the foregoing, upon any failure to settle with respect to
a Book-Entry Note, the Depositary may take any actions in accordance with its
SDFS operating procedures then in effect. In the event of a failure to settle
with respect to one or more, but not all, of the Book-Entry Notes to have been
represented by a Global Certificate, Citibank will provide, in accordance with
Settlement Procedures "D" and "E", for the authentication and issuance of a
Global Certificate representing the other Book-Entry Notes to have been
represented by such Global Certificate and will make appropriate entries in its
records.

                              Medium-Term Notes

Ladies and Gentlemen:

      We have acted as counsel for Ashland Inc., a Kentucky corporation (the
"Company"), in connection with the execution and delivery of a Distribution
Agreement dated December 11, 1996 (the "Distribution Agreement"), between you
and the Company, providing for the issue and sale by the Company of up to
$220,000,000 aggregate principal amount of its Medium-Term Notes, Series H, Due
Nine Months or More from Date of Issue (the "Notes"), to be issued pursuant to
the Indenture dated as of August 15, 1989, as amended and restated as of August
15, 1990 (the "Indenture"), between the Company and Citibank, N.A., as Trustee.

      In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary or appropriate for the purpose
of this opinion, including (a) the Second Restated Articles of Incorporation of
the Company, as amended; (b) the By-laws of the Company, as amended; (c) the
Registration Statement on Form S-3 (No. 33-57011) filed with the Securities and
Exchange Commission (the "Commission"), as amended by Amendment No. 1 and
Post-Effective Amendment No. 1 thereto (the "Registration Statement"), relating
to $600,000,000 aggregate principal amount of securities of the Company
registered under the Securities Act of 1933, as amended (the "Act"); (d) the
Prospectus dated April 24, 1995, as supplemented by the Prospectus Supplement
dated December 11, 1996 (such Prospectus, including all material incorporated by
reference therein, and Prospectus Supplement being hereinafter collectively
called the "Final Prospectus"); (e) the Distribution Agreement; (f) the
Indenture; (g) the form of the Notes; and (h) certain resolutions adopted by the
Board of Directors of the Company on November 3, 1994.

      Based on the foregoing, we are of opinion as follows:

      (a) The Company has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the Commonwealth of Kentucky,
with full 


                                      -1-
<PAGE>

corporate power and authority to own its properties and conduct its business as
described in the Final Prospectus.

      (b) The Company's authorized equity capitalization is as set forth or
incorporated by reference in the Final Prospectus and the Notes conform to the
description thereof contained in the Final Prospectus.

      (c) The Indenture has been duly authorized, executed and delivered by the
Company, has been duly qualified under the Trust Indenture Act of 1939, as
amended, and constitutes a legal, valid and binding instrument enforceable
against the Company in accordance with its terms (subject to applicable
bankruptcy, reorganization, fraudulent transfer, insolvency, moratorium and
other laws affecting creditors' rights generally from time to time in effect).
The enforceability of the Company's obligations is also subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

      (d) The Notes have been duly authorized and, when the terms of any Notes
have been established in accordance with the Indenture and when such Notes have
been executed, authenticated, issued and delivered against payment therefor in
accordance with the provisions of the Indenture, will constitute legal, valid
and binding obligations of the Company enforceable against the Company in
accordance with their terms (subject to applicable bankruptcy, reorganization,
fraudulent transfer, insolvency, moratorium and other laws affecting creditors'
rights generally from time to time in effect) and will be entitled to the
benefits of the Indenture. The enforceability of the Company's obligations is
also subject to general principles of equity (regardless of whether such
enforceability is considered in a proceeding in equity or at law).

      (e) The Distribution Agreement has been duly authorized, executed and
delivered by the Company.

      (f) Neither the issue and sale of the Notes nor the consummation of any
other of the transactions contemplated in the Distribution Agreement nor the
fulfillment of the terms thereof will conflict with, result in a material breach
of, or constitute a material default under, the Second Restated Articles of
Incorporation or By-laws of the Company.

      (g) To the best of our knowledge, no consent, approval, authorization or
order of any court or governmental agency or body is required, insofar as the
same may be applicable to the Company, for the consummation of the transactions
contemplated in the Distribution Agreement except such as have been obtained
under the Act and the Trust Indenture Act and such as may be required under the
blue sky laws of any jurisdiction in connection with the sale of the Notes.

Ladies and Gentlemen:

            Re:   Distribution Agreement by and between
                  CS First Boston Corporation, Salomon
                  BrotheCiticorp Securities, Inc. and Ashland Inc.

      I am Senior Vice President, General Counsel and Secretary of Ashland Inc.,
a Kentucky corporation ("Ashland"), and as such I have acted as counsel for
Ashland in connection with the execution and delivery of a Distribution
Agreement dated December 11, 1996 (the "Distribution Agreement") between you and
Ashland, providing for the issue and sale by Ashland of up to $220,000,000
aggregate principal amount of its Medium-Term Notes, Series H, Due Nine Months
or More from Date of Issue (the "Notes"), to be issued pursuant to the Indenture
dated as of Augustu15,u1989, as amended and restated as of August 15, 1990, (the
"Indenture"), between Ashland and Citibank, N.A., as Trustee.

      In that connection, I have examined originals, or copies certified or
otherwise identified to my satisfaction, of such documents, corporate records
and other instruments as I have deemed necessary or appropriate for the purpose
of this opinion, including (a) the Second Restated Articles of Incorporation of
Ashland, as amended; (b) the By-laws of 

<PAGE>

[DATE]                                                    C-2

Ashland, as amended; (c) the Registration Statement on Form S-3 (File No.
33-57011), as amended by Amendment No. 1 and Post-Effective Amendment No. 1
thereto (the "Registration Statement"), relating to $600,000,000 aggregate
principal amount of securities of Ashland registered under the Securities Act of
1933, as amended (the "Act"); (d) the prospectus dated April 24, 1995 included
in the Registration Statement and the prospectus supplement dated December 11,
1996 (such prospectus together with such prospectus supplement (including all
material incorporated by reference therein) as supplemented or amended to the
date hereof being hereinafter collectively called the "Final Prospectus"); (e)
the Distribution Agreement; (f) the Indenture; (g) the form of the Notes; and
(h) resolutions adopted by the Board of Directors of the Company on November 3,
1994.

      Based upon the foregoing, I am of the opinion that:

      (a) Ashland has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the Commonwealth of Kentucky with
full corporate power and authority to own its properties and conduct its
business as described in the Final Prospectus [, and is duly qualified to do
business as a foreign corporation under the laws of each jurisdiction which
requires such qualification wherein it owns or leases material properties or
conducts material business except for any jurisdiction wherein failure to be so
qualified would not have a material adverse effect on the business, financial
condition or results of operations of Ashland and its subsidiaries, taken as a
whole.]

      (b) Ashland's authorized equity capitalization is as set forth or
incorporated by reference in the Final Prospectus.

      (c) The Indenture has been duly authorized, executed and delivered by
Ashland, and constitutes a legal, valid and binding instrument enforceable
against Ashland in accordance with its terms (subject to applicable bankruptcy,
reorganization, fraudulent transfers, insolvency, moratorium or other laws
relating to and affecting creditors' rights generally from time to time in
effect). The enforceability of Ashland's obligations is also subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

      (d) The Notes have been duly authorized and, when the terms of any Notes
have been established in accordance with the Indenture and have been executed,

authenticated, issued and delivered against payment therefor in accordance with
the provisions of the Indenture, will constitute legal, valid and binding
obligations of Ashland enforceable against Ashland in accordance with their
terms (subject to applicable bankruptcy, reorganization, fraudulent transfer,
insolvency, moratorium or other laws relating to and affecting creditors' rights
generally from time to time in effect) and will be entitled to the benefits of
the Indenture. The enforceability of Ashland's obligations is also subject to
general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).

      (e) To the best knowledge of the undersigned (i) there is no pending or
threatened action, suit or proceeding before any court or governmental agency,
authority or body or any arbitrator involving Ashland or any of its
subsidiaries, the probable outcome of which would have a material adverse effect
on the financial condition of Ashland and its subsidiaries taken as a whole and
which is not adequately disclosed in the Final Prospectus; (ii) there is no
franchise, contract or other document of a character required to be described in
the Registration Statement, as amended, or the Final Prospectus or to be filed
as an exhibit to the Registration Statement, as amended, which is not described
or filed as required; and (iii) the statements included or incorporated in the
Registration Statement, as amended, and the Final Prospectus describing any
legal proceedings or contracts or agreements relating to Ashland fairly
summarize such matters in accordance with the rules under the Act.

      (f) The Registration Statement, as amended, has become effective under the
Act; to the best knowledge of the undersigned, no stop order suspending the
effectiveness of the Registration Statement, as amended, has been issued, no
proceedings for that purpose have been instituted or threatened, and the
undersigned has no reason to believe that any part of the Registration
Statement, as amended, (other than the Form T-1 and the financial statements
including the notes thereto and related schedules and other financial and
statistical data included therein or incorporated therein by reference, as to
which the undersigned expresses no opinion), when such part became effective or
was incorporated by reference into such Registration Statement, contained any
untrue statement of a material fact or omitted to state any material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading or that
the Final Prospectus (other than the financial statements, including the notes
thereto and related schedules and other financial and statistical data included
therein or incorporated therein by reference, as to which the undersigned
expresses no belief), includes any untrue statement of a material fact or omits
to state a material fact necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

      (g) The Distribution Agreement has been duly authorized, executed and
delivered by Ashland.

      (h) To the best knowledge of the undersigned, no consent, approval,
authorization or order of any court or governmental agency or body is required,
insofar as the same may be applicable to Ashland, for the consummation of the
transactions contemplated in the Distribution Agreement, except such as have
been obtained under the Act and the Trust Indenture Act and such as may be
required under the blue sky laws of any jurisdiction in connection with the sale
of the Notes.

      (i) Neither the issue and sale of the Notes, nor the consummation of any
other of the transactions contemplated in the Distribution Agreement nor the
fulfillment of the terms thereof will conflict with, result in a material breach
of, or constitute a material default under the Second Restated Articles of
Incorporation or By-laws of Ashland, each as amended, or the terms of any
indenture or other agreement or instrument known to the undersigned and to which
Ashland or any of its subsidiaries is a party or bound, or any order or
regulation known to the undersigned to be applicable to Ashland or any of its
subsidiaries of any court, regulatory body, administrative agency, governmental
body or arbitrator having jurisdiction over Ashland or any of its subsidiaries.

      (j) No holders of securities of Ashland have rights to the registration of
such securities under the Registration Statement.

      As to certain of the matters referred to in Paragraph (c), Paragraph (d),
Paragraph (e), Paragraph (f) and Paragraph (h) in the foregoing opinion, I have
relied upon the opinion or letter of Cravath, Swaineu& Moore dated the date
hereof, a copy of which opinion or letter is attached hereto and the undersigned
believes that you and the undersigned are justified in relying on such opinion
or letter.

      I am not a member of the bar of any states other than the Commonwealth of
Kentucky and the State of West Virginia and, accordingly, do not purport to be
an expert on matters of law outside of such jurisdictions. I have, however,
reviewed such of the laws of other jurisdictions as I have deemed necessary and
relevant regarding the matters referred to above which are governed by such law
and have no reason to believe that the opinions stated herein are not correct.


                                          Very truly yours,

                                 Ashland Inc.
                              Medium-Term Notes

Ladies and Gentlemen:

      We have acted as counsel for Ashland Inc., a Kentucky corporation (the
"Company"), in connection with the execution and delivery of a Distribution
Agreement dated December 11, 1996, between you and the Company, providing for
the issue and sale by the Company of up to $220,000,000 aggregate principal
amount of its Medium-Term Notes, Series H, Due Nine Months or More from Date of
Issue, to be issued pursuant to the Indenture dated as of August 15, 1989, as
amended and restated as of August 15, 1990, between the Company and Citibank,
N.A, as Trustee.

      In that capacity, we participated in conferences with certain officers of,
and with the accountants for, the Company concerning the preparation of (a) the
Registration Statement on Form S-3 (Registration No. 33-57011) filed with the
Securities and Exchange Commission (the "Commission"), as amended by Amendment
No. 1 and Post-Effective Amendment No. 1 thereto (such Registration Statement,
as amended, being hereinafter called the "Registration Statement"), for
registration of $600,000,000 aggregate principal amount of securities of the
Company under the Securities Act of 1933 (the "Securities Act"); and (b) the
Prospectus dated April 24, 1995, as supplemented by the Prospectus Supplement
dated December 11, 1995 (such Prospectus, including all material incorporated by
reference therein, and Prospectus Supplement being hereinafter collectively
called the "Final Prospectus"). Certain of the documents incorporated by
reference in the Registration Statement and Final Prospectus were prepared and
filed by the Company without our participation.

      Although we have made certain inquiries and investigations in connection
with the preparation of the Registration Statement and the Final Prospectus, the
limitations inherent in the role of outside counsel are such that we cannot and
do not assume responsibility for the accuracy or completeness of the statements
made in the Registration Statement and Final Prospectus, except insofar as such
statements relate to us. Subject to the foregoing, we hereby advise you that our
work in connection with this matter did not disclose any information that gave
us reason to believe that: (i) the Registration Statement, the Final Prospectus
and each amendment or supplement thereto (except the financial statements and
other accounting or financial data included 


                                      -1-
<PAGE>

therein, as to which we do not express any view) were not, as of their
respective effective or issue dates, appropriately responsive in all material
respects to the requirements of the Securities Act and the applicable rules and
regulations of the Commission thereunder, or (ii) the Registration Statement, at
the time the Registration Statement became effective contained an untrue
statement of a material fact or omitted to state a material fact required to be
stated therein or necessary to make the statements therein not misleading, or
that the Final Prospectus or any amendment or supplement thereto, at the date
hereof, include or included an untrue statement of a material fact or omit or
omitted to state a material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading (in each case except for the financial statements and other
accounting or financial data included therein, as to which we do not express any
view).

      We are furnishing this letter to you, as Agents, solely for your benefit.
This letter is not to be used, circulated, quoted or otherwise referred to for
any other purposes.

      Thomas L. Feazell, Esq. and Citibank, N.A., as Trustee, are each entitled
to rely on this letter as fully as if this letter had been addressed to them
directly.

      Upon execution of the Distribution Agreement and, to the extent provided
in Section 7 of the Distribution Agreement, at each Closing Date,(1) Ernst &
Young LLP shall furnish to the Agents or Purchaser, as the case may be, a letter
or letters (which may refer to letters previously delivered to the Agents or
Purchaser, as the case may be), dated as of the date of the Distribution
Agreement or such Closing Date, as the case may be, in form and substance
satisfactory to the Agents or the Purchaser, as the case may be, confirming that
they are independent accountants within the meaning of the Securities Act and
the applicable published rules and regulations thereunder and stating in effect
that:

       (i) in their opinion the consolidated financial statements audited by
them and incorporated by reference in the Registration Statements and the
Prospectus comply as to form in all material respects with the applicable
accounting requirements of the Securities Act and the Exchange Act and the
related published rules and regulations;

       (ii) on the basis of a reading of the latest available interim
consolidated financial statements of the Company, carrying out certain specified
procedures (but not an audit in accordance with generally accepted auditing
standards) which would not necessarily reveal matters of significance with
respect to the comments set forth in such letter, inquiries of officials of the
Company responsible for financial and accounting matters and other specified
procedures, nothing came to their attention that caused them to believe that:

       (A) the unaudited consolidated financial statements, if any, included or
incorporated in the Registration Statements and the Prospectus do not comply as
to form in all material respects with the applicable accounting requirements and
with the published rules and regulations of the Commission with respect to
financial statements included or incorporated in quarterly reports on Form 10-Q
under the Exchange Act, or are not in conformity with generally accepted
accounting principles applied on a basis consistent with that of the audited
financial statements included or incorporated in the Registration Statement and
the Prospectus, except for the accounting changes discussed in the notes
thereto;

       (B) with respect to the period subsequent to the date of the most recent

statements included or incorporated in the Registration Statements or
Prospectus, (i) at the date of the latest available consolidated balance sheet
read by such accountants or (ii) at a subsequent specified date not more than
five days prior to the date of the letter, there was any decrease in the working
capital (but only with respect to the date referred to in the foregoing clause
(i)), any change in capital stock of the Company (except pursuant to existing
stock option, bonus or other similar plans or conversion of debentures or
preferred stock) or increase in long-term debt and debt due within one year, or
decrease in the common stockholders' equity of the Company and its consolidated
subsidiaries (except such changes, increases or decreases which the Prospectus
(directly or by incorporation) discloses have occurred or may occur) as compared
with the amounts shown on the most recent consolidated balance sheet included or
incorporated in the Registration Statements and the Prospectus;

       (C) for the period from the closing date of the most recent consolidated
balance sheet included or incorporated in the Registration Statements and the
Prospectus to the closing date of the latest available consolidated income

OTHER PROVISIONS:


            ASHLAND INC., a corporation duly organized and existing under the
      laws of Kentucky (herein called the "Company", which term includes any
      successor corporation under the Indenture referred to on the reverse
      hereof), for value received, hereby promises to pay to ___________________
      _____________, or registered assigns, the principal sum of _______________
      ___________ U.S. DOLLARS, on the Maturity Date specified above, and to pay
      interest thereon from the Original Issue Date specified above, or from the
      most recent Interest Payment Date to which interest has been paid or duly
      provided for, to but excluding the relevant Interest Payment Date,
      semiannually in arrears on February 15 and August 15 in each year, unless
      otherwise indicated in the applicable pricing supplement, commencing on
      the first such date after the Original Issue Date set forth above, at the
      rate set forth on the face hereof, until the principal hereof is paid or
      made available for payment; provided, however, that if the Original Issue
      Date set forth above is after a Regular Record Date referred to below and
      before the related Interest Payment Date, the first payment of interest
      will be made on the Interest Payment Date following the next succeeding
      Regular Record Date. The interest so payable, and punctually paid or duly
      provided for, on any Interest Payment Date (other than at Maturity) will,
      as provided in 

<PAGE>

3

      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, which shall be the February 1
      or August 1 (whether or not a Business Day), unless otherwise indicated in
      the applicable pricing supplement, as the case may be, 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 whereof 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 at
      the principal corporate trust office of the Trustee in the Borough of
      Manhattan, The City of New York, or such other office or agency of the
      Company as may be designated by it for such purpose in the Borough of
      Manhattan, The City of New York (the "Paying Agent"), 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. 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 

<PAGE>

      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 IN FULL 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 NOTE, SERIES H

                                    (Fixed 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 

<PAGE>

      issued in the name of the Holder hereof upon the surrender hereof.

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


<PAGE>

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

            Interest payments for this Security will include interest accrued to
      but excluding the Interest Payment Date. Interest payments for this
      Security shall be computed and paid on the basis of a 360-day year of
      twelve 30-day months.

            The interest rate on this Security will in no 

<PAGE>

8

      event be higher than the maximum rate permitted by New York law as the
      same may be modified by United States law of general applicability.

            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 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.

            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 

<PAGE>

9

      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 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 

<PAGE>

10

      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.

            ASHLAND INC., a corporation duly organized and existing under the
      laws of Kentucky (herein called the "Company" which term includes any
      successor corporation under the Indenture referred to on the reverse
      hereof), for value received, hereby promises to pay to
      _________________________________ ___________________, or registered
      assigns, the principal sum of ______________ __________________ U.S.
      DOLLARS on the Maturity Date specified above, 

<PAGE>

      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 

<PAGE>

      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 at the principal
      corporate trust office of the Trustee in the Borough of Manhattan, The
      City of New York, or such other office or agency of the Company as may be
      designated by it for such purpose in the Borough of Manhattan, The City of
      New York (the "Paying Agent"), 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. 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-NOTE, SERIES H

                                  (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.

            The Securities of this series will not have a 

<PAGE>

      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.


<PAGE>

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


<PAGE>

            "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:

                                               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. 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


<PAGE>

      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 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 of 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 

<PAGE>

      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 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 =  -------------  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 

<PAGE>

      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". 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 

<PAGE>

      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.

            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 

<PAGE>

      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 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 

<PAGE>

      interest factor will be computed by adding the interest factor calculated
      for each day from and including the Original Issue Date, or from but
      excluding 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 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 

<PAGE>

      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 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 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

<PAGE>

      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 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 

<PAGE>

      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.

OTHER PROVISIONS:


      ASHLAND INC., a corporation duly organized and existing under the laws of
Kentucky (herein called the "Company", which term includes any successor
corporation under the Indenture referred to on the reverse hereof), for value
received, hereby promises to pay to ___________________________________________
________________, or registered assigns, the principal sum of __________________
_____________ U.S. DOLLARS, on the Maturity Date specified above, and to pay
interest thereon from the Original Issue Date specified above, or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, to but excluding the relevant Interest Payment Date, semiannually in
arrears on February 15 and August 15 in each year, unless otherwise indicated in
the applicable Pricing Supplement, commencing on the first such date after the
Original Issue Date set forth above, at the rate set forth on the face hereof,
until the principal hereof is paid or made available for payment; provided,
however, that if the Original Issue Date set forth above is after a Regular
Record Date referred to below and before the related Interest Payment Date, the
first payment of interest will be made on the Interest Payment Date following
the next succeeding Regular Record Date. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date (other than at Maturity)
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, which shall be the
February 1 or August 1 (whether or not a Business Day), unless otherwise
indicated in the applicable Pricing Supplement, as the case may be, 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 whereof 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 Depository, 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

                          MEDIUM-TERM NOTE, SERIES H

                                 (Fixed 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.

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

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

      Interest payments for this Security will include interest accrued to but
excluding the Interest Payment Date. Interest payments for this Security shall
be computed and paid on the basis of a 360-day year of twelve 30-day months.

      The interest rate on this Security will in no event be higher than the
maximum rate permitted by New York law as the same may be modified by United
States law of general applicability.

      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 

<PAGE>

7

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 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 of 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.

      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 

<PAGE>

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 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.

____________________, 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

<PAGE>

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.

                                  (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

      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 

<PAGE>

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 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 

<PAGE>

10

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:

                                               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. 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. 

<PAGE>

$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 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 

<PAGE>

12

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 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 

<PAGE>

13

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:

                                               D x N      
                  Bond Equivalent Yield =  -------------  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 

<PAGE>

14

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". 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 

<PAGE>

15

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.

      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 

<PAGE>

16

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 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 
<PAGE>

17

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 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 

<PAGE>

18

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 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.


<PAGE>

19

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


<PAGE>

20

      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.
