description of the notes being offered and the terms of the offering. The
pricing supplement may also add, update or change information in this
prospectus supplement or the attached prospectus. Any information in the

                                      S-3



                           DESCRIPTION OF THE NOTES

General

   The following summary of certain terms of the notes is not complete. You
should refer to the senior indenture with U.S. Bank National Association, as
trustee, under which the notes will be issued, a copy of which has been filed
as an exhibit to the registration statement. The definitions of certain
capitalized terms used in this prospectus supplement are provided in the
glossary beginning on page S-22. A number of terms used but not defined in this
prospectus supplement (including the glossary) have the same meanings as in the
indenture.

   The notes will be "senior securities" as described in the attached
prospectus. The notes will constitute one series of senior securities issued
under the indenture. They will have the same rank as all of our other senior
securities. See "Description of Debt Securities" in the attached prospectus.

   We will offer the notes on a continuing basis. Each note will mature nine
months or more from its date of issue, as agreed between us and the initial
purchaser.

   We will not redeem any note prior to the redemption date fixed at the time
of sale and set forth in the attached pricing supplement. If the pricing
supplement does not indicate a redemption date for a note, we will not redeem
the note before its stated maturity. Unless the attached pricing supplement
indicates otherwise, on or after any indicated redemption date, we may, at our
option, redeem the related note wholly or partially in increments of $1,000. If
we choose to redeem the note, we will do so at the redemption price described
in the attached pricing supplement, together with interest payable to the date
of redemption. We must give notice of this redemption not more than 60 nor less
than 30 days prior to the redemption date. The notes will not have a sinking
fund unless the attached pricing supplement specifies otherwise.

   We may provide that any note will be repayable at the holder's option, at
the times and on the terms and conditions set forth in the note and described
in the attached pricing supplement.

   The notes may bear interest at (a) a fixed rate or (b) a floating rate.
Interest on floating rate notes will be determined, and adjusted periodically,
using an interest rate basis or quotation, adjusted by any spread or spread
multiplier. See "Interest and Interest Rates" below.

   Unless the attached pricing supplement specifies otherwise, the notes will
be denominated in U.S. dollars and payments of principal of and interest on the
notes will be made in U.S. dollars. If denominated in U.S. dollars, the notes
will be issued in denominations of $1,000 and multiples of $1,000 greater than
$1,000. The attached pricing supplement will set forth the authorized
denominations of notes not denominated in U.S. dollars and additional
information. This information would include any exchange rate information,
relevant for these notes and notes for which principal, premium, if any, and
interest may be payable at the holder's or our option in a denomination
different from that of the note. See "Special Provisions Relating to Foreign
Currency Notes" below.

   Each note will be issued in fully registered form without coupons. Each note
will be issued either in definitive form as a certificate or in global form and
deposited with or on behalf of DTC, as depositary, in book-entry form as
described in the attached prospectus under the caption ''Description of Debt
Securities--Global Securities''. Unless the attached pricing supplement
specifies otherwise, each note will be issued in book-entry form. Beneficial
interests in a book-entry note will be shown on records maintained by DTC or
its participants. Transfers of the beneficial interests can only be effected
through those records. Holders may not exchange book-entry notes for
certificated notes and book-entry notes will not generally be issuable in
definitive form. The attached prospectus describes the exceptions to this. We
will make payments of principal, any premium and interest on book-entry notes
to DTC or its nominee. DTC and its participants will make payments to
beneficial owners of interests in book-entry notes. A further description of
the depositary's procedures regarding global securities representing book-entry
notes is set forth in the attached prospectus under "Description of Debt
Securities--Global Securities". DTC has confirmed to the agents, the trustee
and us that it intends to follow those procedures.

                                      S-4



   You may present certificated notes for registration of transfer or exchange
at the corporate trust office of U.S. Bank National Association located at 425
Walnut Street, Sixth Floor, Cincinnati, Ohio 45202. Unless the attached pricing
supplement indicates otherwise, we will make payments of principal, premium, if
any, and interest on certificated notes in immediately available funds at the
paying agent's office located at 425 Walnut Street, Sixth Floor, Cincinnati,
Ohio 45202, or another office or agency we may choose. However, we will make
payments in these funds only if the certificated notes are presented to the
paying agent in time for the paying agent to make the payments through normal
procedures. At our option, we may pay interest on the certificated notes by
check to the person in whose name a certificated note is registered at the
close of business on the applicable regular record date before each interest
payment date. This option does not apply for interest payable at maturity.
However, certain holders will be entitled to receive the payments by wire
transfer of immediately available funds to an account maintained by that holder
with a bank located in the U.S. These holders include any holders of
$10,000,000 or more in aggregate principal amount of notes denominated and
payable in U.S. dollars with the same interest payment date. To take this
option, these holders must provide appropriate payment instructions in writing
to the trustee on or before the relevant regular record date.

   We have initially designated U.S. Bank National Association, acting through
its principal corporate trust office in located at 425 Walnut Street,
Cincinnati, Ohio 42505, as paying agent for the certificated notes.

   Except as described in the attached prospectus under the heading "Certain
Rights to Require Purchase of Securities by Ashland Upon Unapproved Change in
Control and Decline in Debt Rating", the indenture does not contain any
covenants or provisions designed to protect the holders of the notes if we
enter into a transaction that adversely affects our debt-to-equity ratio.

   For a description of the rights attaching to different series of debt
securities under the indenture, see ''Description of Debt Securities'' in the
prospectus.

Interest and Interest Rates

   The applicable pricing supplement will designate whether a particular note
is a fixed rate note or a floating rate note. In the case of a floating rate
note, the attached pricing supplement will also specify whether the note will
bear interest based on the commercial paper rate, the prime rate, LIBOR, the
Treasury rate, the Federal funds rate, the CD rate or on another interest rate
quotation set forth in the attached pricing supplement. In addition, a floating
rate note may bear interest at the lowest, highest or average of two or more
interest rate quotations.

   We will select an interest rate or interest rate quotations for each issue
of notes based on market conditions at the time of issuance. In doing so, we
will take into account, among other things, expectations concerning the level
of interest rates that will prevail during the period the notes will be
outstanding, the relative attractiveness of the interest rate or interest rate
quotation to prospective investors and our financial needs. Unless the attached
pricing supplement provides otherwise, U.S. Bank National Association will be
the calculation agent with respect to the floating rate notes.

   We may change the interest rates, or interest rate quotations at various
times. No such change will affect any note already issued or for which we have
accepted an offer to purchase.

   The rate of interest on floating rate notes will reset daily, weekly,
monthly, quarterly, semi-annually or annually. The interest reset dates will be
specified in the attached pricing supplement and on the face of each note. In
addition, the pricing supplement will specify any spread, spread multiplier,
maximum interest rate or minimum interest rate that applies for a floating rate
note. The pricing supplement relating to an offering of notes may also specify,
where applicable, the calculation dates, index maturity, initial interest rate,
interest determination dates, interest payment dates, interest reset dates and
regular record dates with respect to each note. See "Glossary" on beginning
page S-22 for definitions of the above terms. The interest rate on the notes
will in no event be higher than the maximum rate permitted by applicable law.
Under New York law in effect on the date of this prospectus supplement, the
maximum annual interest rate on a simple interest basis is 25%. The limit may
not apply to notes in which $2,500,000 or more has been invested.

                                      S-5



   Each interest bearing note will accrue interest from and including the date
of issue or the most recent interest payment date for which interest has been
paid or provided. The notes will bear interest until the principal is paid or
made available for payment. We will make any interest payments in the amount of
interest accrued in the manner described up to but excluding the applicable
interest payment date.

   We will pay any interest at each interest payment date and at maturity. See
"Description of Debt Securities--Payment and Paying Agents" in the prospectus.
We will pay interest to the person in whose name a note is registered at the
close of business on the regular record date preceding the interest payment
date. However, we will pay interest at maturity to the person to whom principal
is payable. For book-entry notes, this person will be the depositary for both
kinds of payments. Interest on a note will be payable on the first interest
payment date following its date of issue. However, if the date of a note's
issue is on or after the regular record date for that interest payment date,
interest will be payable beginning on the second interest payment date
following the note's issue.

Fixed Rate Notes

   The applicable pricing supplement relating to a fixed rate note will
designate a fixed annual interest rate payable on the fixed rate note. Unless
the attached pricing supplement indicates otherwise, the interest payment dates
for the fixed rate notes will be February 15 and August 15 of each year and at
maturity. The regular record dates for the fixed rate notes will be the
February 1 and August 1 preceding the February 15 and August 15 interest
payment dates. Unless the attached pricing supplement indicates otherwise,
interest on fixed rate notes will be computed on the basis of a 360-day year of
twelve 30-day months.

Floating Rate Notes

   Upon the request of a registered holder of a floating rate note, the
calculation agent will provide the interest rate then in effect. The
calculation agent will also provide any new interest rate that will become
effective as a result of a determination the calculation agent has made on the
most recent interest determination date with respect to that floating rate
note.

   The calculation agent will calculate accrued interest on a floating rate
note by multiplying the principal amount of the note by an accrued interest
factor. The calculation agent will compute the accrued interest factor by
adding the interest factors calculated for each day in the accrual period.
Unless the attached pricing supplement specifies otherwise, the calculation
agent will compute the interest factor for each day by dividing the interest
rate for that day by (a) the actual number of days in the year, in the case of
treasury rate notes or (b) 360, in the case of all other floating rate notes.

   The interest rate on a floating rate note in effect on any day will be (a)
if the day is an interest reset date, the interest rate with respect to the
interest determination date for that interest reset date, or (b) if the day is
not an interest reset date, the interest rate with respect to the interest
determination date for the preceding interest reset date. However, the interest
rate on a floating rate note from its issue date up to but not including the
first interest reset date for the note will be the initial interest rate set
forth in the attached pricing supplement. The interest rate is subject to
adjustment by any spread or a spread multiplier and to any maximum interest
rate or minimum interest rate limitation. However, the interest rate for the
ten calendar days prior to the date of maturity will be the one in effect on
the tenth calendar day before maturity.

   All percentages resulting from any calculation of floating rate notes will
be rounded to the nearest one-hundred thousandth of a percentage point, with
five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or
 .09876545) being rounded to 9.87655% (or .0987655), and 9.876544% (or
 .09876544) being rounded to 9.87654% (or .0987654)), and all dollar amounts
used in or resulting from this calculation will be rounded to the nearest cent
(with one-half cent being rounded upwards).

                                      S-6



   Commercial Paper Rate Notes. Commercial paper rate notes will bear interest
at the interest rates (calculated with reference to the commercial paper rate
and any spread or spread multiplier) specified on the face of the commercial
paper rate note and in the attached pricing supplement.

   Unless the attached pricing supplement indicates otherwise, the "commercial
paper rate" for any commercial paper interest determination date is the money
market yield of the rate on that date for commercial paper having the index
maturity specified in the pricing supplement as published in H.15(519) prior to
3:00 P.M., New York City time, on the calculation date relating to that
commercial paper interest determination date under the heading "Commercial
Paper--Nonfinancial".

   The following procedures will be followed if the commercial paper rate
cannot be determined as described above:

  .  If the above rate is not published in H.15(519) by 3:00 P.M., New York
     City time, on the calculation date, the commercial paper rate will be the
     money market yield of the rate on that commercial paper rate interest
     determination date for commercial paper having the index maturity
     designated in the pricing supplement, as published in H.15 Daily Update
     under the heading "Commercial Paper--Nonfinancial".

  .  If that rate is not published in H.15 Daily Update by 3:00 P.M., New York
     City time, on the calculation date, then the calculation agent will
     determine the commercial paper rate to be the money market yield of the
     average of certain offered rates of three leading dealers of commercial
     paper in New York City as of 11:00 A.M., New York City time, on that
     commercial paper rate interest determination date. These offered rates
     will be for commercial paper having the index maturity specified in the
     pricing supplement for a non-financial issuer whose bond rating is "Aa",
     or the equivalent, from a nationally recognized rating agency. The
     calculation agent will select the three dealers referred to above, which
     may include the agents or their affiliates.

  .  If fewer than three dealers selected by the calculation agent are quoting
     as mentioned above, the commercial paper rate will be the commercial paper
     rate in effect on that commercial paper rate interest determination date.

   Prime Rate Notes. A prime rate note will bear interest at the interest rate
(calculated with reference to the prime rate and any spread or spread
multiplier) specified on the face of the prime rate note and in the attached
pricing supplement.

   Unless the attached pricing supplement indicates otherwise, the "prime rate"
for any prime rate interest determination date is the prime rate on that date,
as published in H.15(519) by 3:00 P.M., New York City time, on the calculation
date relating to that prime rate interest determination date under the heading
"Bank Prime Loan".

   The following procedures will be followed if the prime rate cannot be
determined as described above:

  .  If the above rate is not published in H.15(519) by 3:00 P.M., New York
     City time, on the calculation date, then the prime rate will be the rate
     on that prime rate interest determination date as published in H.15 Daily
     Update opposite the caption "Bank Prime Loan".

  .  If that rate is not published in H.15 Daily Update by 3:00 P.M., New York
     City time, on the calculation date, then the calculation agent will
     determine the prime rate to be the average of certain interest rates
     publicly announced by each bank that appears on the Reuters Screen
     USPRIME1 Page. For each bank, those announced rates will be that bank's
     prime rate or base lending rate in effect for that prime rate interest
     determination date at 11:00 A.M. New York City time.

  .  If fewer than four of those rates appear on the Reuters Screen USPRIME1
     Page for that prime rate interest determination date, then the prime rate
     will be the average of the announced prime rates quoted (on the basis of
     the actual number of days in the year divided by 360) by at least three
     major money

                                      S-7



     center banks in New York City as of the close of business on that prime
     rate interest determination date. The calculation agent will select the
     banks referred to above, which may include the agents or their affiliates.

  .  If fewer than two quotations are provided as mentioned in the previous
     item, the prime rate will be determined on the basis of the rates
     furnished in New York City by the appropriate number of substitute banks
     or trust companies organized and doing business under the laws of the
     United States, or any state. These substitute banks must have total equity
     capital of at least $500 million and subject to supervision or examination
     by Federal or state authority. The calculation agent will select the banks
     or trust companies referred to above.

  .  If the banks or trust companies described in the previous item are not
     quoting as mentioned above, the prime rate will be the prime rate in
     effect on that prime rate interest determination date.

   LIBOR Notes. A LIBOR note will bear interest at the interest rate
(calculated with reference to LIBOR and any spread or spread multiplier)
specified on the face of the LIBOR note and in the attached pricing supplement.

   Unless the attached pricing supplement indicates otherwise, the calculation
agent will determine LIBOR as follows:

   On each LIBOR rate interest determination date:

  .  If "LIBOR Reuters" is specified in the attached pricing supplement, LIBOR
     will be the average of certain offered rates for deposits in the index
     currency having the index maturity specified in the pricing supplement
     beginning on the applicable interest reset date. Those rates will be the
     ones which appear on the designated LIBOR page as of 11:00 A.M., London
     time, on that LIBOR rate interest determination date, if at least two of
     those offered rates appear on the designated LIBOR page. If the designated
     LIBOR page provides only for a single rate, that single rate will be used
     regardless of the foregoing provisions requiring more than one rate.

  .  If "LIBOR Telerate" is specified in the attached pricing supplement, LIBOR
     will be a certain rate for deposits in the index currency having the index
     maturity specified in the pricing supplement beginning on that interest
     reset date. That rate will be the one which appears on the designated
     LIBOR page as of 11:00 A.M., London time, on that LIBOR rate interest
     determination date.

  .  If neither "LIBOR Reuters" nor "LIBOR Telerate" is specified in the
     attached pricing supplement as the method for calculating LIBOR, LIBOR
     will be calculated as if ''LIBOR Telerate'' had been specified.

   On any LIBOR rate interest determination date on which fewer than two of
those offered rates appear or no rate appears, as applicable, on the designated
LIBOR page, the calculation agent will determine LIBOR as follows:

  .  LIBOR will be determined on the basis of the offered rates at which
     deposits in the index currency having the index maturity specified in the
     applicable pricing supplement beginning on the applicable interest reset
     date and in a principal amount that is representative for a single
     transaction in that index currency in that market at that time by four
     major banks in the London interbank market (which may include the agents
     or their affiliates) at approximately 11:00 A.M., London time, on that
     LIBOR rate interest determination date to prime banks in the London
     interbank market. The calculation agent will select the four banks and
     request the principal London office of each of those banks to provide a
     quotation of its rate. If at least two quotations are provided, LIBOR on
     that LIBOR rate interest determination date will be the average of those
     quotations.

  .  If fewer than two of those quotations are provided as mentioned above,
     LIBOR on that LIBOR rate interest determination date will be the average
     of the rates quoted at approximately 11:00 A.M., in the

                                      S-8



     applicable principal financial center, on that LIBOR rate interest
     determination date by three major banks in that principal financial center
     (which may include the agents or their affiliates) for loans in the index
     currency to leading European banks, having the index maturity specified in
     the applicable pricing supplement and in a principal amount representative
     for a single transaction in that index currency in that market at that
     time. The calculation agent will select the three banks referred to above.

  .  If the banks selected by the calculation agent are not quoting as
     mentioned above, LIBOR will be LIBOR in effect on the LIBOR rate interest
     determination date.

   Treasury Rate Notes. A Treasury rate note will bear interest at the interest
rate (calculated with reference to the Treasury rate and any spread or spread
multiplier) specified on the face of the Treasury rate note and in the attached
pricing supplement.

   Unless the attached pricing supplement indicates otherwise, "Treasury rate"
for any Treasury rate interest determination date means a certain rate from the
most recent auction of direct obligations of the United States ("Treasury
bills") having the index maturity specified in the pricing supplement. That
rate will be the one that appears on the display designated as page 56 or the
display designated as page 57 on the Dow Jones Telerate Service under the
heading "AVGE INVEST YIELD".

   The following procedures will be followed if the Treasury rate cannot be
determined as described above:

  .  If the above rate is not displayed on the relevant page by 3:00 P.M., New
     York City time, on the calculation date, the Treasury rate will be the
     auction average rate for that auction as otherwise announced by the United
     States Department of the Treasury. The auction average rate will be
     expressed as a bond equivalent on the basis of a year of 365 or 366 days,
     as applicable, and applied on a daily basis.

  .  If the results of the auction of Treasury bills having the index maturity
     specified in the pricing supplement are not published or reported as
     provided above by 3:00 P.M., New York City time, on the calculation date,
     or if no auction is held in a particular week, then the Treasury rate will
     be the rate as published in H.15(519) under the heading "U.S. Government
     Securities/Treasury Bills/Secondary Market".

  .  If the rate described in the previous item is not published by 3:00 P.M.,
     New York City time, on the calculation date, then the calculation agent
     will determine the Treasury rate to be a yield to maturity of the average
     of certain secondary market bid rates, as of approximately 3:30 P.M., New
     York City time, on that Treasury rate interest determination date. The bid
     rates will be those of three leading primary U.S. government securities
     dealers in New York City for the issue of Treasury bills with a remaining
     maturity closest to the index maturity specified in the pricing
     supplement. The rates will be expressed as a bond equivalent on the basis
     of a year of 365 or 366 days, as applicable, and applied on a daily basis.
     The calculation agent will select the three dealers referred to above,
     which may include the agents or their affiliates.

  .  If fewer than three dealers selected by the calculation agent are quoting
     as mentioned above, the Treasury rate will be the Treasury rate in effect
     on that Treasury rate interest determination date.

   Federal Funds Rate Notes. A Federal funds rate note will bear interest at
the interest rate calculated with reference to the Federal funds rate and any
spread or spread multiplier, as specified on the face of the Federal funds rate
note and in the attached pricing supplement.

   Unless the attached pricing supplement indicates otherwise, the "Federal
funds rate" for any Federal funds rate interest determination date is the rate
on that day for Federal funds as published in H.15(519) prior to 3:00 P.M., New
York City time, on the calculation date relating to that Federal funds rate
interest determination date under the heading "Federal Funds (Effective)".

                                      S-9



   The following procedures will be followed if the Federal funds rate cannot
be determined as described above:

  .  If the above rate is not published in H.15(519) by 3:00 P.M., New York
     City time, on the calculation date, the Federal funds rate will be the
     rate on that Federal funds rate interest determination date for U.S.
     dollar Federal funds, as published in H.15 Daily Update under the heading
     "Federal Funds (Effective)".

  .  If that rate is not published in H.15 Daily Update by 3:00 P.M., New York
     City time, on the calculation date, then the calculation agent will
     determine the Federal funds rate to be the average of certain rates for
     the last transaction in overnight Federal funds as of 9:00 A.M., New York
     City time, on that Federal funds rate interest determination date. The
     rates will be ones arranged by three leading brokers of Federal funds
     transactions in New York City. The calculation agent will select the three
     brokers referred to above.

  .  If fewer than three brokers selected by the calculation agent are quoting
     as mentioned above, the Federal funds rate will be the Federal funds rate
     in effect on that Federal funds rate interest determination date.

   CD Rate Notes. A CD rate note will bear interest at the interest rate
(calculated with reference to the CD rate and any spread or spread multiplier)
specified in the CD rate note and in the attached pricing supplement.

   Unless the attached pricing supplement indicates otherwise, the ''CD rate''
for any CD rate interest determination date is the rate on that date for
negotiable certificates of deposit having the index maturity specified in the
pricing supplement, as published in H.15(519) prior to 3:00 P.M., New York City
time, on the calculation date relating to that CD rate interest determination
date under the heading "CDs (Secondary Market)".

   The following procedures will be followed if the CD rate cannot be
determined as described above:

  .  If the above rate is not published by 3:00 P.M., New York City time, on
     the calculation date, the CD rate will be the rate on that CD rate
     interest determination date for negotiable certificates of deposit of the
     index maturity specified in the pricing supplement as published in H.15
     Daily Update under the caption "CDS (Secondary Market)".

  .  If that rate is not published in H.15 Daily Update by 3:00 P.M., New York
     City time, on the calculation date, then the calculation agent will
     determine the CD rate to be the average of certain secondary market
     offered rates as of 10:00 A.M., New York City time, on that CD rate
     interest determination date. The offered rates will be ones quoted by
     three leading nonbank dealers in negotiable U.S. dollar certificates of
     deposit in New York City. The dealers will provide quoted rates for
     negotiable certificates of deposit in a denomination of $5,000,000 of
     major U.S. 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 designated in the applicable pricing
     supplement. The calculation agent will select the three dealers referred
     to above.

  .  If fewer than three dealers are quoting as mentioned above, the CD rate
     will be the CD rate in effect on that CD rate interest determination date.

Indexed Notes

   We may issue notes as indexed notes, as indicated in the attached pricing
supplement. Holders of indexed notes may receive a principal amount at maturity
that is greater than or less than the face amount of the notes depending upon
the fluctuation of the relative value, rate or price of the specified index.
The attached pricing supplement will describe specific information relating to
the method for determining the principal amount payable at maturity, a
historical comparison of the relative value, rate or price of the specified
index and the face amount of the indexed note and certain additional tax
considerations.

Other Provisions; Addenda

   Any provisions relating to any note may be modified as specified under
"Other Provisions" on the face of that note or in an addendum relating to that
note. These provisions might include the determination of an interest rate
basis, the calculation of the interest rate applicable to a floating rate note,
and the specification of one or more interest rate bases, the interest payment
dates, the maturity, any early redemption provisions, or any other variable
term relating to that note.

             SPECIAL PROVISIONS RELATING TO FOREIGN CURRENCY NOTES

General

   Unless the attached pricing supplement indicates otherwise, the notes will
be denominated in U.S. dollars and we will make payments of principal of and
interest on the notes in U.S. dollars. If we designate any of the notes to be
denominated in a currency or currency unit other than U.S. dollars the
following provisions will apply. These provisions are in addition to and, where
inconsistent, replace the description of general terms and provisions of notes
set forth in the attached prospectus and elsewhere in this prospectus
supplement. We refer below to any currency or currency unit designated in this
manner as the "specified currency."

   Notes not denominated in U.S. dollars are issuable in registered form only,
without coupons. The pricing supplement will specify the denominations for
particular foreign currency notes.

   Unless the attached pricing supplement provides otherwise, you are required
to pay the purchase price of foreign currency notes in immediately available
funds.

   Notes denominated in specified currencies other than euros will not be sold
in, or to residents of, the country of the specified currency in which
particular notes are denominated unless the pricing supplement specifies
otherwise.

Currencies

   Unless the attached pricing supplement specifies otherwise, you are required
to pay for foreign currency notes in the specified currency. At the present
time there are limited facilities in the United States for the conversion of
U.S. dollars into the specified currencies and vice versa, and banks do not
generally offer non-U.S. dollar checking or savings accounts in the United
States. However, you may ask the agent who presented your offer to purchase
foreign currency notes to us to use its reasonable best efforts to arrange for
the exchange of U.S. dollars into the relevant specified currency to enable you
to pay for the notes. You must make this request on or before the third
business day preceding the delivery date for the note or by a later date if
allowed by the agent. Each exchange will be made on the terms and conditions
established by the agent in accordance with its regular foreign exchange
practices and you will pay for all related costs.

   The attached pricing supplement will contain specific information about the
foreign currency or currency units in which a particular foreign currency note
is denominated, including historical exchange rates and a description of the
currency and any exchange controls.

Payment of Principal and Interest

   We will pay the principal of and interest on foreign currency notes in U.S.
dollars. However, unless the attached pricing supplement specifies otherwise,
the holder of a foreign currency note may elect to receive the payments in the
specified currency as described below. The exchange rate agent will determine
the rate of conversion for all payments of principal of and interest on foreign
currency notes to U.S. dollars. "Exchange rate agent" means the agent appointed
by us to make those determinations. Unless the pricing supplement specifies
otherwise, the exchange rate agent will be U.S. Bank National Association.

   Unless the attached pricing supplement specifies otherwise, any U.S. dollar
amount to be received by a holder of a foreign currency note will be based on
the following:

  .  The highest bid quotation in New York City received by the exchange rate
     agent at approximately 11:00 A.M., New York City time, on the second
     business day preceding the applicable payment date from three recognized
     foreign exchange dealers (one of which may be the exchange rate agent or
     an agent) for the purchase by the quoting dealer of the specified currency
     for U.S. dollars for settlement on that payment

                                     S-11



     date in the aggregate amount of the specified currency payable to all
     holders of foreign currency notes scheduled to receive U.S. dollar
     payments and at which the applicable dealer commits to execute a contract.
     The exchange rate agent will select and we will approve that selection of
     the three dealers referred to above.

  .  If fewer than three of these bid quotations are available, payments will
     be made in the specified currency.

   The holder of the foreign currency note will bear all of these currency
exchange costs through payment deductions.

   Unless the attached pricing supplement specifies otherwise, a holder of
foreign currency notes may elect to receive payment of the principal of and
interest on the notes in the specified currency by transmitting a request for
the payment to the corporate trust department of U.S. Bank National Association
in Cincinnati, Ohio, on or before the regular record date or at least sixteen
days before maturity, as the case may be. The request must be in writing
(mailed or hand delivered) or by cable, telex or other form of facsimile
transmission. If a holder elects to receive all principal and interest payments
in the specified currency that holder need not file a separate election for
each payment. The election will remain in effect until revoked by written
notice to U.S. Bank National Association in Cincinnati, Ohio. Written notice of
any revocation of this kind must be received by U.S. Bank National Association
in Cincinnati, Ohio on or before the regular record date or at least sixteen
days before maturity, as the case may be. Holders of foreign currency notes
held in the name of a broker or nominee should contact that broker or nominee
to determine whether and how an election to receive payments in the specified
currency may be made.

   We will pay interest on and principal of foreign currency notes paid in U.S.
dollars in the manner specified in the attached prospectus and elsewhere in
this prospectus supplement. Interest on foreign currency notes paid in the
specified currency will be paid by a check drawn on an account maintained at a
bank outside the United States, unless other arrangements have been made. The
principal and interest due at maturity of foreign currency notes paid in the
specified currency will be paid in immediately available funds by wire transfer
to an account maintained with a bank outside the United States designated at
least sixteen days before maturity by the holders. However, those foreign
currency notes must be presented to the trustee or the paying agents designated
in the attached pricing supplement to allow time for payment. Any payment of
principal or interest required to be made on an interest payment date or at
maturity of a foreign currency note that is not a business day may be made
instead on the following business day. In this case, no interest will accrue
for the period from and after the interest payment date or maturity.

Payment Currency

   At various times, a specified currency may not available for the payment of
principal or interest with respect to a foreign currency note due to the
imposition of exchange controls or other circumstances beyond our control. If
this is the case, we will be entitled to satisfy our obligations to holders of
foreign currency notes by making the payment in U.S. dollars on the basis of
the market exchange rate on the date of payment, or if the market exchange rate
is not available at that time, on the basis of the most recently available
market exchange rate.

                            UNITED STATES TAXATION

General

   This section summarizes the material U.S. tax consequences to holders of
notes. It represents the views of our tax counsel, Cravath, Swaine & Moore.
However, the discussion is limited in the following ways:

  .  The discussion only covers you if you buy your notes in the initial
     offering.

  .  The discussion only covers you if you hold your notes as a capital asset
     (that is, for investment purposes), and if you do not have a special tax
     status.

  .  The discussion does not cover tax consequences that depend upon your
     particular tax circumstances. You should consult your tax advisor about
     the consequences of holding notes in your particular situation.

  .  The discussion is based on current law. Changes in the law may change the
     tax treatment of the notes.

  .  The discussion does not cover state, local or foreign law.

  .  The discussion does not cover every type of note that we might issue. If
     we intend to issue a note of a type not described in this summary,
     additional tax information will be provided in the pricing supplement for
     the note.

  .  The discussion does not apply to you if you are a non-U.S. holder of notes
     and if you (a) own 10% or more of the voting stock of the company, (b) are
     a "controlled foreign corporation" with respect to the company, or (c) are
     a bank making a loan in the ordinary course of its business.

  .  We have not requested a ruling from the Internal Revenue Service on the
     tax consequences of owning the notes. As a result, the IRS could disagree
     with portions of this discussion.

   If you are considering buying notes, you should consult your tax advisors
about the tax consequences of holding the notes in your particular situation.

Tax Consequences to U.S. Holders

  .  This section applies to you if you are a "U.S. Holder". A "U.S. Holder"
     is:

  .  an individual U.S. citizen or resident alien;

  .  a corporation, or entity taxable as a corporation, that was created under
     U.S. law (Federal or state); or

  .  an estate or trust whose world-wide income is subject to U.S. Federal
     income tax.

   If a partnership holds notes, the tax treatment of a partner will generally
depend upon the status of the partner and upon the activities of the
partnership. Partners of partnerships holding notes should consult their tax
advisors.

   Interest. The tax treatment of interest paid on the notes depends upon
whether the interest is "Qualified Stated Interest."

   "Qualified Stated Interest" is any interest that meets all the following
conditions:

  .  It is payable at least once each year.

  .  It is payable over the entire term of the note.

  .  It is payable at a single fixed rate or under a single formula.

  .  The note has a maturity of more than one year from its issue date.

   If any interest on a note is Qualified Stated Interest, then

  .  If you are a cash method taxpayer (including most individual holders), you
     must report that interest in your income when you receive it.

  .  If you are an accrual method taxpayer, you must report that interest in
     your income as it accrues.

  .  If any interest on a note is not Qualified Stated Interest, it is subject
     to the rules for original issue discount (''OID'') described below.

                                     S-13



   Determining Amount of OID. Notes that have OID are subject to additional tax
rules. The amount of OID on a note is determined as follows:

  .  The amount of OID on a note is the "stated redemption price at maturity"
     of the note minus the "issue price" of the note. If this amount is
     negative, there is no OID.

  .  The "stated redemption price at maturity" of a note is the total amount of
     all principal and interest payments to be made on the note, other than
     Qualified Stated Interest. In a typical case where all interest is
     Qualified Stated Interest, the stated redemption price at maturity is the
     same as the principal amount.

  .  The "issue price" of a note is the first price at which a substantial
     amount of the notes are sold to the public.

  .  Under a special rule, if the OID determined under the general formula is
     very small, it is disregarded and not treated as OID. This disregarded OID
     is called "de minimis OID". If all the interest on a note is Qualified
     Stated Interest, this rule applies if the amount of OID is less than the
     following items multiplied together: (a) .25% (1/4 of 1%), (b) the number
     of full years from the issue date to the maturity date of the note, and
     (c) the principal amount.

   Accrual of OID Into Income. If a note has OID, the following consequences
arise:

  .  A holder must include the total amount of OID as ordinary income over the
     life of the note.

  .  All holders of notes, even those on the cash method of accounting, must
     include OID in income as the OID accrues on the notes. This means that
     holders are required to report OID income, and in some cases pay tax on
     that income, before they receive the cash that corresponds to that income.

  .  OID accrues on a note on a "constant yield" method. This method takes into
     account the compounding of interest. Under this method, the accrual of OID
     on a note, combined with the inclusion into income of any Qualified Stated
     Interest on the note, will result in the holder being taxable at
     approximately a constant percentage of the unrecovered investment in the
     note.

  .  The accruals of OID on a note will generally be less in the early years
     and more in the later years.

  .  If any of the interest paid on the note is not Qualified Stated Interest,
     that interest is included in the stated redemption price at maturity and
     taken into account as OID. It is not separately taxed when it is paid to
     the holder.

  .  Your tax basis in the note is initially your cost. It increases by any OID
     you report as income. It decreases by any principal payments you receive
     on the note, and by any interest payments you receive that are not
     Qualified Stated Interest.

   Notes Subject to Additional Tax Rules. Additional or different tax rules
apply to several types of notes that we may issue.

   Short-Term Notes: We may issue notes with a maturity of one year or less.
These are referred to as "short-term notes."

  .  No interest on these notes is Qualified Stated Interest. Otherwise, the
     amount of OID is calculated in the same manner as described above.

  .  Certain elections apply to the method of accrual of OID on short-term
     notes over the life of the notes.

  .  Accrual method taxpayers and certain others, such as banks and securities
     dealers, must include OID in income as it accrues.

  .  If you are a cash method taxpayer not subject to the accrual rule
     described above, you do not include OID in income until you actually
     receive payments on the note. Alternatively, you can elect to include OID
     in income as it accrues.

                                     S-14



  .  Two special rules apply if you are a cash method taxpayer and you do not
     include OID in income as it accrues. First, if you sell the note or it is
     paid at maturity, and you have a taxable gain, then the gain is ordinary
     income to the extent of the accrued OID on the note at the time of the
     sale that you have not yet taken into income. Second, if you borrow money
     (or, in certain circumstances, do not repay outstanding debt) to acquire
     or hold the note, then while you hold the note you cannot deduct any
     interest on the borrowing that corresponds to accrued OID on the note
     until you include the OID in your income.

   Floating Rate Notes: Floating rate notes are subject to special OID rules.

  .  If the interest rate is based on a single fixed formula based on objective
     financial information (which may include a fixed interest rate for the
     initial period if the value of the floating note on the issue date is
     intended to approximate the fixed rate), all the interest will be
     Qualified Stated Interest. The amount of OID (if any), and the method of
     accrual of OID, will then be calculated by converting the note's initial
     floating rate into a fixed rate and by applying the general OID rules
     described above.

  .  If the note has more than one formula for interest rates, it is possible
     that the combination of interest rates might create OID. You should
     consult your tax advisor concerning the OID accruals on such a note.

   Foreign Currency Notes: Special tax rules apply to foreign currency notes:

  .  If you are a cash method taxpayer, you will be taxed on the U.S. dollar
     value of any foreign currency you receive as interest. The dollar value
     will be determined as of the date when you receive the payments.

  .  If you are an accrual method taxpayer, you must report interest income as
     it accrues. You can use the average foreign currency exchange rate during
     the relevant interest accrual period (or, if that period spans two taxable
     years, during the portion of the interest accrual period in the relevant
     taxable year). In this case, you will make an adjustment (which will
     constitute ordinary income or loss rather than interest income or expense)
     upon receipt of the foreign currency to reflect actual exchange rates at
     that time. Certain alternative elections may also be available.

  .  Any OID on foreign currency notes will be determined in the relevant
     foreign currency. All holders must accrue OID in the same manner that an
     accrual basis holder accrues interest income, as described in the previous
     paragraphs.

  .  Your initial tax basis in a foreign currency note is the amount of U.S.
     dollars you pay for the note (or, if you pay in foreign currency, the
     value of that foreign currency on the purchase date). Adjustments are made
     to reflect OID and other items as described above.

  .  If you collect foreign currency upon the maturity of the note, or if you
     sell the note for foreign currency, your gain or loss will be based on the
     U.S. dollar value of the foreign currency you receive. For a publicly
     traded foreign currency note, this value is determined for cash basis
     taxpayers on the settlement date for the sale of the note, and for accrual
     basis taxpayers on the trade date for the sale (although such taxpayers
     can also elect the settlement date). You will then have a tax basis in the
     foreign currency equal to the value reported on the sale.

  .  Any gain or loss on the sale or retirement of a note will be ordinary
     income or loss to the extent it arises from currency fluctuations between
     your purchase date and sale date. Any gain or loss on the sale of foreign
     currency will also be ordinary income or loss.

   Other Categories of Notes: Additional rules may apply to certain other
categories of notes. The pricing supplement for these notes may describe these
rules. In addition, you should consult your tax advisor in these situations.
These categories of notes include:

  .  Notes with contingent payments;

                                     S-15



  .  Notes that can be put to the company by the holder before their maturity;

  .  Notes that are callable by the company before their maturity, other than
     typical calls at a premium;

  .  Indexed notes with an index tied to currencies; and

  .  Notes that are extendable at the option of the company or the holder.

   Premium and Discount. Additional special rules apply in the following
situations involving discount or premium:

  .  If you buy a note in the initial offering for more than its stated
     redemption price at maturity, the excess amount you pay will be "bond
     premium". You can elect to use bond premium to reduce your taxable
     interest income over the life of your note.

  .  Similarly, if a note has OID and you buy it in the initial offering for
     more than the issue price, the excess (up to the total amount of OID) is
     called "acquisition premium". The amount of OID you are required to
     include in income will be reduced by this amount over the life of the
     note.

  .  If you buy a note in the initial offering for less than the initial
     offering price to the public, special rules concerning "market discount"
     may apply.

   Appropriate adjustments to tax basis are made in these situations. Holders
in these situations should consult their tax advisors.

   Accrual Election. You can elect to be taxed on the income from the note in a
different manner than described above. Under the election:

  .  No interest is Qualified Stated Interest.

  .  You include amounts in income as it economically accrues to you. The
     accrual of income is in accordance with the constant yield method, based
     on the compounding of interest. The accrual of income takes into account
     stated interest, OID (including de minimis OID), market discount, and
     premium.

  .  Your tax basis is increased by all accruals of income and decreased by all
     payments you receive on the note.

  .  If you are considering making this election with respect to a note, you
     should consult your tax advisor concerning the consequences of making the
     election (including the effect on other debt instruments you hold).

   Sale or Retirement of Notes. On your sale or retirement of your note:

  .  You will have taxable gain or loss equal to the difference between the
     amount received by you and your tax basis in the note. Your tax basis in
     the note is your cost, subject to certain adjustments.

  .  Your gain or loss will generally be capital gain or loss, and will be long
     term capital gain or loss if you held the note for more than one year.

  .  If (a) you purchased the note with de minimis OID, (b) you did not make
     the election to accrue all OID into income, and (c) you receive the
     principal amount of the note upon the sale or retirement, then you will
     generally have capital gain equal to the amount of the de minimis OID.

  .  If you sell the note between interest payment dates, a portion of the
     amount you receive reflects interest that has accrued on the note but has
     not yet been paid by the sale date. That amount is treated in the same
     manner as interest and not as sale proceeds.

  .  All or part of your gain may be ordinary income rather than capital gain
     in certain cases. These cases include sales of short-term notes, notes
     with market discount, notes with contingent payments, or foreign currency
     notes.

                                     S-16



   Information Reporting and Backup Withholding. Under the tax rules concerning
information reporting to the IRS:

  .  Assuming you hold your notes through a broker or other securities
     intermediary, the intermediary must provide information to the IRS
     concerning interest, OID and retirement proceeds on your notes, unless an
     exemption applies.

  .  Similarly, unless an exemption applies, you must provide the intermediary
     with your Taxpayer Identification Number for its use in reporting
     information to the IRS. If you are an individual, this is your social
     security number. You are also required to comply with other IRS
     requirements concerning information reporting.

  .  If you are subject to these requirements but do not comply, the
     intermediary must withhold tax at the rates specified in the Code
     (currently 30.5%) of all amounts payable to you on the notes (including
     principal payments). If the intermediary withholds payments, you may use
     the withheld amount as a credit against your federal income tax liability.

  .  All individual U.S. Holders are subject to these requirements. Some U.S.
     Holders, including all corporations, tax-exempt organizations and
     individual retirement accounts, are exempt from these requirements.

Tax Consequences to Non-U.S. Holders

   This section applies to you if you are a "Non-U.S. Holder." A "Non-U.S.
Holder" is:

  .  an individual that is a nonresident alien;

  .  a corporation organized or created under non-U.S. law; or

  .  an estate or trust that is not taxable in the U.S. on its worldwide
     income.

   Withholding Taxes. Generally, payments of principal and interest on the
Notes will not be subject to U.S. withholding taxes.

   However, for the exemption from withholding taxes to apply to you in the
case of interest, you must meet one of the following requirements:

  .  You provide your name, address, and a signed statement that you are the
     beneficial owner of the Note and are not a U.S. Holder. This statement is
     generally made on Form W-8BEN.

  .  You hold your Notes directly through a "qualified intermediary", and the
     qualified intermediary has sufficient infromation in its files indicating
     that you are not a U.S. Holder. A qualified intermediary is a bank, broker
     or other intermediary that (1) is either a U.S. or non-U.S. entity, (2) is
     acting out of a non-U.S. branch or office and (3) has signed an agreement
     with the IRS providing that it will administer all or part of the U.S. tax
     withholding rules under specified procedures.

  .  You or your agent claim an exemption from withholding tax under an
     applicable tax treaty. This claim is generally made on Form W-8BEN.

  .  You or your agent claim an exemption from withholding tax on the ground
     that the income is effectively connected with the conduct of a trade or
     business in the United States. This claim is generally made on Form
     W-8ECI.

   You should consult your tax advisor about the specific methods for
satisfying these requirements. A claim for exemption will not be valid if the
person receiving the applicable form knows or has reason to know that the
statements on the form are false.

   Even if you comply with these conditions, withholding tax might arise if the
amount of interest payable on a note is based on the earnings or other
attributes of the company. If this exception applies, additional information
will be provided in the applicable pricing supplement.

                                     S-17



   Sale or Retirement of Notes. If you sell a note or it is redeemed, you will
not be subject to federal income tax on any gain unless one of the following
applies:

  .  The gain is connected with a trade or business that you conduct in the
     United States.

  .  You are an individual, you are present in the United States for at least
     183 days during the year in which you dispose of the note, and certain
     other conditions are satisfied.

  .  The gain represents accrued interest or OID, in which case the rules for
     interest would apply.

   U.S. Trade or Business. If you hold your note in connection with a trade or
business that you are conducting in the United States:

  .  Any interest on the note, and any gain from disposing of the note,
     generally will be subject to income tax as if you were a U.S. Holder.

  .  If you are a corporation, you may be subject to the "branch profits tax"
     on your earnings that are connected with your U.S. trade or business,
     including earnings from the note. This tax is 30%, but may be reduced or
     eliminated by an applicable income tax treaty.

   Estate Taxes. If you are an individual, your notes will not be subject to
U.S. estate tax when you die. However, this rule only applies if, at your
death, payments on the notes were not connected to a trade or business that you
were conducting in the United States and none of the interest payable on the
note is based on the earnings as other attributes of the company.

   Information Reporting and Backup Withholding. U.S. rules concerning
information reporting and backup withholding are described above. These rules
apply to Non-U.S. Holders as follows:

  .  Principal and interest payments you receive will be automatically exempt
     from the usual rules if you provide the tax certifications needed to avoid
     withholding tax on interest, as described above. The exemption does not
     apply if the recipient of the applicable form knows or has reason to know
     that the form is false. In addition, interest payments made to you will be
     reported to the IRS on Form 1042-S.

  .  Sale proceeds you receive on a sale of your notes through a broker may be
     subject to information reporting and/or backup withholding if you are not
     eligible for an exemption. In particular, information reporting and backup
     reporting may apply if you use the U.S. office of a broker, and
     information reporting (but not backup withholding) may apply if you use
     the foreign office of a broker that has certain connections to the United
     States. You should consult your tax advisor concerning information
     reporting and backup withholding on a sale.

                             PLAN OF DISTRIBUTION

   Under the terms of a distribution agreement, a form of which is attached as
an exhibit to the registration statement, we will offer the notes on a
continuing basis through Credit Suisse First Boston Corporation, J.P. Morgan
Securities Inc., Salomon Smith Barney Inc., and Banc of America Securities LLC,
as our agents, each of which has agreed to use reasonable efforts to solicit
purchases of the notes. Unless the applicable pricing supplement indicates
otherwise, we will pay a commission to the agents. We will have the sole right
to accept offers to purchase notes and may reject any offer, in whole or in
part. Each agent will have the right, in its discretion reasonably exercised,
without notice to us, to reject any offer to purchase notes received by it, in
whole or in part.

   We also may sell notes at or above par to any agent, acting as principal,
for a commission equivalent to that set forth on the cover page of this
prospectus supplement. The notes may be resold at market prices prevailing at
the time of resale, at prices related to those prevailing market prices, at a
fixed offering price or at negotiated prices, as determined by that agent. We
also may sell notes at or above par to any agent or to a group of underwriters
for whom an agent acts as representative. We may do this for a commission to be
agreed at the time of sale, for resale to one or more investors or purchasers
at a fixed offering price or at varying prices prevailing at the time of
resale, at prices related to those prevailing market prices at the time of the
resale or at negotiated prices. Notes purchased by an agent or by a group of
underwriters may be resold to certain securities dealers for resale to
investors or to certain other dealers. Dealers may receive compensation in the
form of commissions from the agents and/or from the purchasers for whom they
may act as agents. Unless the applicable pricing supplement specifies
otherwise, any compensation allowed by any agent to any of these dealers shall
not be in excess of the commission received by that agent from us. After the
initial public offering of notes to be resold to investors and other purchasers
on a fixed public offering price basis, the public offering price and
commission may be changed.

   We have reserved the right to sell notes directly on our own behalf. We also
may accept but not solicit offers to purchase notes through additional agents
on substantially the same terms and conditions (including commission rates) as
would apply to purchases of notes under the distribution agreement. In
addition, we have reserved the right to appoint additional agents for the
purpose of soliciting offers to purchase notes. Those additional agents will be
named in the applicable pricing supplement. No commission will be payable on
any notes sold directly by us.

   We will pay each agent a commission of from .125% to .750% of the principal
amount of each note, depending on its stated maturity, sold through that agent.

   The following table summarizes the compensation to be paid to the agents by
us.



                                                         Total

    Commissions paid by Ashland............ .125%-.750% $437,500 $2,625,000


   We estimate that we will incur expenses of $230,000 in connection with this
program.

   The agents and any dealers to whom the agents may sell notes may be deemed
to be "underwriters" within the meaning of the Securities Act of 1933. We have
agreed to indemnify the agents against certain liabilities, including civil
liabilities under the Securities Act of 1933, or contribute to payments which
the agents may be required to make in this regard. We have agreed to reimburse
the agents for certain expenses.

   Unless the applicable pricing supplement indicates otherwise, you must pay
for notes, other than foreign currency notes in funds immediately available in
New York City. For payment of the purchase price of foreign currency notes, see
''Description of the Notes--Foreign Currency Notes'' above.

                                     S-19



   The notes are a new issue of securities with no established trading market
and will not be listed on any securities exchange. No assurance can be given as
to the existence or liquidity of the secondary market for the notes.

   The agents may engage in over-allotment, stabilizing transactions and
syndicate covering transactions and may impose penalty bids in accordance with
Regulation M under the Securities Exchange Act of 1934. Over-allotment involves
syndicate sales in excess of the offering size, which creates a syndicate short
position. Stabilizing transactions permit bids to purchase the underlying
security so long as the stabilizing bids do not exceed a specified maximum.
Syndicate covering transactions involve purchases of the notes in the open
market after the distribution has been completed in order to cover syndicate
short positions. Penalty bids permit the agents to reclaim a selling concession
from a syndicate member when the notes originally sold by that syndicate member
are purchased in a syndicate covering transaction to cover syndicate short
positions. These stabilizing transactions, syndicate covering transactions and
penalty bids may cause the price of the notes to be higher than it would
otherwise be in the absence of the transactions. These transactions, if
commenced, may be discontinued at any time.

   In the ordinary course of their respective businesses, the agents and their
affiliates have engaged, and may in the future engage, in commercial banking
and/or investment banking transactions with us and our affiliates.

                                LEGAL OPINIONS

   Opinions regarding the validity of the notes being offered will be issued
for us by Cravath, Swaine & Moore, New York, New York (who will rely as to
matters of Kentucky law upon the opinion of David L. Hausrath, Esq., our Vice
President and General Counsel), and for the agents by Davis Polk & Wardwell,
New York, New York. In these opinions, certain assumptions will be made
regarding future action required to be taken by us and the trustee in
connection with the issuance and sale of any particular notes, the specific
terms of those notes and other matters which may affect the validity of notes
but which cannot be ascertained on the date of the relevant opinions. Cravath,
Swaine & Moore has in the past represented and continues to represent us in
other matters on a regular basis. Samuel C. Butler is a director of ours and a
partner in the law firm of Cravath, Swaine & Moore and, as of the date of this
prospectus supplement, owns beneficially 74,009 shares of our common stock

                                   GLOSSARY

   Set forth below are definitions of some of the terms used in this prospectus
supplement and not defined in the attached prospectus.

   ''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 New York City;

      (b) with respect to foreign currency notes (other than foreign currency
   notes denominated in euro only), not a day on which banking institutions are
   authorized or required by law or regulation to be closed in the principal
   financial center in the country of the specified currency;

      (c) with respect to foreign currency notes denominated in euro, any date
   on which the Trans-European Automated Real-Time Gross Settlement Express
   Transfer (TARGET) System is open; and

      (d) with respect to LIBOR notes, a London banking day.

   "calculation agent" means the agent appointed by us to calculate interest
rates for floating rate notes. Unless the pricing supplement specifies
otherwise, the calculation agent will be U.S. Bank National Association.

   ''calculation date'' means, with respect to any interest determination date,
the date on which the calculation agent is to calculate an interest rate for a
floating rate note. Unless the pricing supplement specifies otherwise, the
calculation date relating to an interest determination date for a floating rate
note will be the first to occur of (a) the tenth calendar day after that
interest determination date, or, if that day is not a business day, the next
succeeding business day or (b) the business day preceding the applicable
interest payment date or maturity of that note, as the case may be. However,
LIBOR will be calculated on the LIBOR rate interest determination date.

   ''designated LIBOR page'' means (a) if ''LIBOR Reuters'' is specified in the
applicable pricing supplement, the display on the Reuter Monitor Money Rates
Service (or any successor service) on the page specified in that pricing
supplement (or any other page as may replace that page on that service) for the
purpose of displaying the London interbank rates of major banks for the
applicable index currency, or (b) if ''LIBOR Telerate'' is specified in the
applicable pricing supplement as the method for calculating LIBOR, the display
on the Dow Jones Telerate Service (or any successor service) on the page

at http://www.bog.frb.fed.us/releases/h15/update, or any successor site or
publication.

   ''index currency'' means the currency or composite currency specified in the
applicable pricing supplement as to which LIBOR will be calculated. If no
currency or composite currency of this kind is specified in the applicable
pricing supplement, the index currency will be U.S. dollars.

   ''index maturity'' means, for a floating rate note, the period to maturity
of the instrument or obligation on which the interest rate quotation is based,
as set forth in the pricing supplement.

   ''initial interest rate'' means the rate at which a floating rate note will
bear interest from and including its issue date to but excluding the first
interest reset date, as indicated in the applicable pricing supplement.

                                     S-22



   ''interest determination date'' means the date as of which the interest rate
for a floating rate note is to be calculated, to be effective as of the
following interest reset date and calculated on the related calculation date.
However, LIBOR will be calculated on the LIBOR rate interest determination
date. The interest determination date relating to an interest reset date for a
commercial paper rate note, for a prime rate note, for a Federal funds rate
note and for a CD rate note will be the second business day preceding that
interest reset date. The interest determination date relating to an interest
reset date for a LIBOR note will be the second London banking day preceding
that interest reset date. The interest determination date relating to an
interest reset date for a Treasury rate note will be the day of the week during
which that interest reset date falls on which Treasury bills of the index
maturity designated in the pricing supplement 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 or may be held on the preceding Friday. If, as the result of
a legal holiday, an auction is so held on the preceding Friday, that Friday
will be the Treasury interest rate determination date pertaining to the
interest reset date occurring in the following week.

   ''interest payment date'' means the date on which payment of interest on a
note (other than payment at maturity) is to be made. Unless the applicable
pricing supplement indicates otherwise, the interest payment dates for the
fixed rate notes will be February 15 and August 15 of each year and at
maturity. Unless the applicable pricing supplement indicates otherwise and
except as provided below, the interest payment dates for any floating rate note
will be:

      (a) in the case of floating rate notes that reset weekly, on the third
   Wednesday of March, June, September and December of each year;

      (b) in the case of floating rate notes that reset daily or monthly, on
   the third Wednesday of each month or on the third Wednesday of March, June,
   September and December of each year (as indicated in the pricing
   supplement);

      (c) in the case of floating rate notes that reset quarterly, on the third
   Wednesday of March, June, September and December of each year, in the case
   of floating rate notes that reset semi-annually, on the third Wednesday of
   the two months of each year specified in the pricing supplement;

      (d) in the case of floating rate notes that reset annually, on the third
   Wednesday of the month specified in the pricing supplement; and

      (e) in each case, at maturity.

If an interest payment date for any fixed rate note falls on a day that is not
a business day for that note, the interest payment for that note will be made
on the following business day for that note, and no interest on that payment
will accrue from and after that interest payment date. If an interest payment
date (other than an interest payment date at maturity) for any floating rate
note would otherwise be a day that is not a business day for that note, that
interest payment date will be postponed to the next business day for that note,
and interest will continue to accrue (except that, for a LIBOR note, if that
business day is in the following calendar month, that interest payment date
will be the preceding business day for that LIBOR note).

   "interest reset date" means the date on which a floating rate note will
begin to bear interest at the interest rate determined as of any interest
determination date. Unless the pricing supplement specifies otherwise, the
interest reset dates will be:

      (a) in the case of floating rate notes that reset daily, each business
   day;

      (b) in the case of floating rate notes (other than Treasury rate notes)
   that reset weekly, the Wednesday of each week;

      (c) in the case of Treasury rate notes that reset weekly, the Tuesday of
   each week (except as provided below);

      (d) in the case of floating rate notes that reset monthly, the third
   Wednesday of each month;

      (e) in the case of floating rate notes that reset quarterly, the third
   Wednesday of March, June, September and December of each year;

                                     S-23



      (f) in the case of floating rate notes that reset semi-annually, the
   third Wednesday of each of two months of each year specified in the pricing
   supplement; and

      (g) in the case of floating rate notes that reset annually, the third
   Wednesday of one month of each year specified in the pricing supplement.

If any interest reset date for any floating rate note would otherwise be a day
that is not a business day for that floating rate note, that interest reset
date will be postponed to the next business day for that floating rate note
(except that, for a LIBOR note, if that business day is in the following
calendar month, that interest reset date will be the preceding business day for
that LIBOR note). If a Treasury bill auction (as described in the definition of
''interest determination date'') falls on any day that would otherwise be an
interest reset date for a Treasury rate note, then that interest reset date
will instead be the first business day following that auction date.

   ''London banking day'' means any day on which dealings in deposits in U.S.
dollars are transacted in the London interbank market.

   ''market exchange rate'' for any specified currency means the noon buying
rate in New York City for cable transfers for that specified currency as
certified for customs purposes by (or if not certified, as otherwise determined
by) The Federal Reserve Bank of New York.

   ''maturity'' means the date on which the principal of a note becomes due,
whether at stated maturity, upon redemption or otherwise. If the maturity of
any note falls on a day that is not a business day, the payment of principal,
premium, if any, and interest for that note will be made on the following
business day, and no interest on that payment will accrue from and after that
maturity.

   ''maximum interest rate'' means, for any floating rate note, a maximum
numerical interest rate limitation, or ceiling, on the rate at which interest
may accrue on that during any interest period.

   ''minimum interest rate'' means, for any floating rate note, a minimum
numerical interest rate limitation, or floor, on the rate at which interest may
accrue on that during any interest period.

   ''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:


                                             
                                              DX360
                                            --------- X 100
                     money market yield =   360-(DXM)


where ''D'' refers to the annual rate for the 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.

   ''paying agent'' means the agent appointed by us to make payments of
principal, premium, if any, and interest on the notes. Unless the pricing
supplement specifies otherwise, the paying agent will be U.S. Bank National
Association.

   ''principal financial center'' means the capital city of the country issuing
the index currency, except that with respect to U.S. dollars, Australian
dollars, Deutsche marks, Dutch guilders, Italian lire and Swiss francs, the
principal financial center will be New York City, Sydney, Frankfurt, Amsterdam,
Milan and Zurich, respectively.

   ''regular record date'' means the date on which a note must be held in order
for the holder to receive an interest payment on the next interest payment
date. Unless the pricing supplement specifies otherwise, the regular record
date for any interest payment date with respect to any floating rate note will
be the fifteenth day (whether or not a business day) prior to that interest
payment date. The regular record dates for the fixed rate notes will be the
February 1 and August 1 next preceding the February 15 and August 15 interest
payment dates.

                                     S-24



   ''Reuters Screen USPRIME1 Page'' means the display on the Reuters Monitor
Money Rates Service (or any successor service) on the ''USPRIME1'' page (or any
other page as may replace the USPRIME1 page on such service) for the purpose of
displaying prime rates or base lending rates of major U.S. banks.

   ''spread'' means the number of basis points, if any, to be added to the
commercial paper rate, the prime rate, LIBOR, the Treasury rate, the Federal
funds rate, the CD rate or any other interest rate index in effect at various
times for a note, which amount will be set forth in the pricing supplement.

   ''spread multiplier'' means the percentage by which the commercial paper
rate, the prime rate, LIBOR, the Treasury rate, the Federal funds rate, the CD
rate or any other interest rate index in effect at various times for a note is
to be multiplied, which percentage will be set forth in the pricing supplement.

                          The Securities We May Offer

   This prospectus is part of a registration statement (No. 333-.) that we
filed with the SEC utilizing a "shelf" registration process. Under this shelf
process, we may offer from time to time up to $600,000,000 of any of the
following securities, either separately or in units: debt securities, preferred
stock, depositary shares, common stock and warrants. This prospectus provides
you with a general description of the securities we may offer. Each time we
offer securities, we will provide you with a prospectus supplement that will
describe the specific amounts, prices and terms of the securities being
offered. The prospectus supplement may also add, update or change information
contained in this prospectus.

Debt Securities

   We may offer unsecured general obligations of our company, which may be
senior or subordinated. The senior securities and the subordinated securities
are together referred to in this prospectus as the "debt securities".

                                      1



The subordinated securities will be entitled to payment only after payment on
our superior indebtedness (as described below).

   Unless the applicable prospectus supplement states otherwise, senior
securities will be issued under an indenture dated as of September 7, 2001,
between us and U.S. Bank National Association, as trustee. The subordinated
securities will be issued under an indenture between us and a commercial bank
to be selected, as trustee. We have summarized certain general features of the
debt securities from the indentures. We encourage you to read the indentures
(which are exhibits to the registration statement) and our recent periodic and
current reports that we file with the SEC. Directions on how you can get copies
of these reports are provided on page 4.

General Indenture Provisions that Apply to Senior and Subordinated Securities

  .  Neither indenture limits the amount of debt that we may issue or provides
     holders any protection should there be a highly leveraged transaction,
     recapitalization or restructuring involving our company.

  .  The indentures provide that holders of two-thirds of the total principal
     amount of outstanding debt securities of any series may vote to change
     certain of our obligations or certain of your rights concerning the debt
     securities of that series. However, to change the amount or timing of
     principal, interest or other payments under the debt securities every
     holder in the series must consent.

  .  If an event of default (as described below) occurs with respect to any
     series of debt securities, the trustee or holder of 25% of the outstanding
     principal amount of that series may declare the principal amount of the
     series immediately payable. However, holders of a majority of the
     principal amount may rescind this action except where a payment default or
     a breach of certain covenants has occurred.

  .  If we satisfy certain conditions in either indenture, we may discharge
     that indenture at any time by depositing with the trustee sufficient funds
     or government obligations to pay when due the debt securities outstanding
     under that indenture.

  .  Not all debt securities of any one series need be issued at the same time,
     and, unless otherwise provided, a series may be reopened for issuance of
     additional debt securities of such series.

   Events of Default. The indentures provide that the following are events of
default:

  .  Interest not paid for 30 days after due date.

  .  Principal or premium not paid when due.

  .  Sinking fund payment not paid for 30 days after due date.

  .  Covenant breach continuing for 60 days after notice.

  .  Occurrence of certain bankruptcy or insolvency events.

  .  Occurrence of any other event of default specified in the prospectus
     supplement.

General Indenture Provisions that Apply Only to Senior Securities

  .  The indenture relating to the senior securities limits our ability and the
     ability of any subsidiary of ours to assume or guarantee indebtedness
     secured by mortgages, liens or other encumbrances upon our or our
     subsidiary's property unless the senior securities will be equally and
     ratably secured with that indebtedness.

                                      2



  .  The indenture relating to the senior securities limits our ability and the
     ability of any subsidiary of ours to sell or transfer property to a lender
     or investor, which then, either directly or indirectly, leases the
     property back to us or the subsidiary for a time period over three years.

  .  The indenture relating to the senior securities states that we may not
     merge or consolidate with another company or sell all or substantially all
     of our assets to another company unless certain conditions are met. If
     these events occur, the other company will be required to assume our
     responsibilities relating to the debt securities, and we will be released
     from all liabilities and obligations.

General Indenture Provisions that Apply Only to Subordinated Securities

   The subordinated securities will be subordinated to all "superior
indebtedness", which includes all indebtedness for money borrowed by us, except
indebtedness that is stated to be not superior to, or to have the same rank as,
the subordinated securities.

Preferred Stock and Depositary Shares

   We may issue our preferred stock, without par value, in one or more series.
We will determine the dividend, voting, conversion and other rights of the
series being offered and the terms and conditions relating to its offering and
sale at the time of the offer and sale. We may also issue fractional shares of
preferred stock that will be represented by depositary shares and depositary
receipts.

Common Stock

   We may issue our common stock, par value $1.00 per share. Holders of common
stock are entitled to receive dividends when declared by our board of directors
(subject to rights of preferred stockholders). Each holder of common stock is
entitled to one vote per share. The holders of common stock have cumulative
voting rights but no preemptive, redemption or conversion rights.

Warrants

   We may issue warrants for the purchase of debt securities, preferred stock
or common stock. We may issue warrants independently or together with other
securities.

RATIOS OF EARNINGS TO FIXED CHARGES AND EARNINGS TO COMBINED FIXED CHARGES AND
                           PREFERRED STOCK DIVIDENDS

   The following table sets forth the ratios of earnings to fixed charges and
earnings to combined fixed charges and preferred stock dividends for Ashland:



                                                                                Nine Months
                                                                                   Ended
                                                Fiscal Year Ended September 30,  June 30,
                                                ------------------------------- -----------
                                                 1996   1997  1998  1999  2000  2000  2001
                                                 ----   ----  ----  ----  ----  ----  ----
                                                                 
Ratio of earnings to fixed charges............. 1.90   2.42   2.32  3.67  2.61  2.08  3.51
Ratio of earnings to combined fixed charges and
  preferred stock dividends.................... 1.66   2.24   2.32  3.67  2.61  2.08  3.51


   The above ratios are computed on a total enterprise basis including our
consolidated subsidiaries, plus our share of significant affiliates accounted
for on the equity method that are 50% or greater owned or whose indebtedness
has been directly or indirectly guaranteed by us. Earnings consist of income
from continuing operations before income taxes, adjusted to exclude fixed
charges (excluding capitalized interest) and

                                      3



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.

offered by this prospectus and the accompanying prospectus supplement for
general corporate purposes, unless we specify otherwise in the applicable
prospectus supplement. General corporate purposes may include additions to
working capital, capital expenditures, stock redemption or repurchases,
repayment of debt or the financing of acquisitions.

                        DESCRIPTION OF DEBT SECURITIES

   The following description sets forth the general terms and provisions that
could apply to the debt securities. Each prospectus supplement will state the
particular terms that actually will apply to the debt securities included in
the supplement.

   The debt securities will be either our senior debt securities or our
subordinated debt securities. Unless the applicable prospectus supplement
states otherwise, senior securities will be issued under an indenture dated as
of September 7, 2001, between us and U.S. Bank National Association, as
trustee. Under the indenture between us and U.S. Bank National Association, as
trustee, no senior securities have been issued. Subordinated securities will be
issued under an indenture between us and a commercial bank to be selected, as
trustee. The senior indenture and the subordinated indenture are together
called the "indentures".

   The following summary of certain provisions of the indentures is not
complete. You should refer to the applicable provisions of the following
documents for more detailed information:

  .  the senior indenture has been filed as Exhibit 4.1 to the Registration
     Statement of which this prospectus is a part, and


                                      5



  .  the subordinated indenture, which is incorporated by reference to Exhibit
     4.3 to Registration Statement No. 33-57011, filed with the SEC on December
     22, 1994.

Some of the capitalized terms used in the following discussion are defined in
the indentures, and their definitions are incorporated by reference into this
prospectus.

General

   Neither indenture limits the aggregate principal amount of debt securities
that we may issue under that indenture. The debt securities may be issued in
one or more series as we may authorize at various times. All debt securities
will be unsecured. The senior securities will have the same rank as all of our
other unsecured and unsubordinated debt. The subordinated securities will be
subordinated to superior indebtedness as described in the "Subordinated
Securities" section below. The prospectus supplement relating to the particular
series of debt securities being offered will specify the amounts, prices and
terms of those debt securities. These terms may include:

  .  the title and the limit on the aggregate principal amount of the debt
     securities;

  .  the date or dates on which the debt securities will mature;

  .  any annual rate or rates (which may be fixed or variable), or the method
     of determining any rate or rates, at which the debt securities will bear
     interest;

  .  the date or dates from which interest shall accrue and the date or dates
     on which interest will be payable;

  .  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;

  .  whether such debt securities are to be senior securities or subordinated
     securities;

  .  any redemption or sinking fund terms;

  .  any event of default or covenant with respect to the debt securities of a
     particular series, if not set forth in this prospectus;

  .  whether the debt securities will be issued as registered securities or as
     bearer securities;

  .  whether the debt securities are to be issued in whole or in part in the
     form of one or more global securities and the depositary for the global
     security or securities; and

  .  any other terms of the series, which will not conflict with the terms of
     applicable indenture.

   Principal, any premium and any interest will be payable and the debt
securities will be transferable at the corporate trust office of the
appropriate trustee, unless we specify otherwise in the accompanying prospectus
supplement. At our option, however, payment of interest may be made by check
mailed to the registered holders of the debt securities at their registered
addresses.

   We will issue the debt securities in fully registered form without coupons
unless the applicable prospectus supplement provides for an issuance to be in
bearer form with or without coupons. Unless we specify otherwise in the
applicable prospectus supplement, we will issue debt securities denominated in
U.S. dollars in denominations of $1,000 or multiples of $1,000 for registered
securities and in denominations of $5,000 or multiples of $5,000 for bearer
securities. No service charge will be made for any transfer or exchange of debt
securities, but we may require payment beforehand of any related taxes or other
governmental charges. Debt securities may also be issued pursuant to the
indentures in transactions exempt from the registration requirements of the
Securities Act of 1933. Those debt securities will not be considered in
determining the aggregate amount of securities issued under the registration
statement.

                                      6



   We will describe special Federal income tax and other considerations
relating to debt securities denominated in foreign currencies or units of two
or more foreign currencies in the applicable prospectus supplement.

   Unless we specify otherwise in the applicable prospectus supplement, the
covenants contained in the indentures and the debt securities will not provide
special protection to holders of debt securities if we enter into a highly
leveraged transaction, recapitalization or restructuring.

Exchange, Registration and Transfer

   Registered securities of any series that are not global securities will be
exchangeable for other registered securities of the same series and of like
aggregate principal amount and tenor in different authorized denominations. In
addition, if debt securities of any series are issuable as both registered
securities and bearer securities, the holder may choose, upon written request,
and subject to the terms of the applicable indenture, to exchange bearer
securities and the appropriate related coupons of that series into registered
securities of the same series of any authorized denominations and of like
aggregate principal amount and tenor. Bearer securities with attached coupons
surrendered in exchange for registered securities between a regular record date
or a special record date and the relevant date for interest payment shall be
surrendered without the coupon relating to the interest payment date. Interest
will not be payable with respect to the registered security issued in exchange
for that bearer security. That interest will be payable only to the holder of
the coupon when due in accordance with the terms of the applicable indenture.
Bearer securities will not be issued in exchange for registered securities.

   You may present debt securities for exchange as provided above. In addition,
you may present registered securities for registration of transfer, together
with a duly executed form of transfer, at the office of the security registrar
or at the office of any transfer agent designated by us for that purpose with
respect to any series of debt securities and referred to in the applicable
prospectus supplement. This may be done without service charge and upon payment
of any taxes and other governmental charges as described in the applicable
indenture. The security registrar or the transfer agent will effect the
transfer or exchange upon being satisfied with the documents of title and
identity of the person making the request. We have appointed the applicable
trustee as security registrar for the applicable indenture. If a prospectus
supplement refers to any transfer agents (in addition to the security
registrar) initially designated by us with respect to any series of debt
securities, we may at any time rescind the designation of any such transfer
agent or approve a change in the location through which such transfer agent
acts. However, if debt securities of a series are issuable solely as registered
securities, we 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, we will be required to maintain (in addition to the security
registrar) a transfer agent in a place of payment for such series located
outside the United States. We may at any time designate additional transfer
agents with respect to any series of debt securities.

   In the event of any redemption in part, we will not be required to:

  .  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:

    .  if debt securities of the series are issuable only as registered
       securities, the day of mailing of the relevant notice of redemption;

    .  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

    .  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,
       or the date of such publication, if applicable;

  .  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

                                      7



  .  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 restriction on the exchange, registration and transfer
of global securities, see "Global Securities" below.

Payment and Paying Agents

   Unless we specify otherwise in the applicable prospectus supplement, payment
of principal, any premium and interest on bearer securities will be payable, in
accordance with any applicable laws and regulations, at the offices of those
paying agents outside the U.S. that we may designate at various times. We will
make interest payments on bearer securities and the attached coupons on any
interest payment date only against surrender of the coupon relating to that
interest payment date. No payment with respect to any bearer security will be
made at any of our offices or agencies in the U.S., by check mailed to any U.S.
address or by transfer to an account maintained with a bank located in the U.S.
However, if (but only if) payment in U.S. dollars of the full amount of
principal, any premium and interest on bearer securities denominated and
payable in U.S. dollars at all offices or agencies outside the U.S. is illegal
or effectively precluded by exchange controls or other similar restrictions,
then those payments will be made at the office of our paying agent.

   Unless we specify otherwise in the applicable prospectus supplement, payment
of principal, any premium and any interest on registered securities will be
made at the office of the paying agent or paying agents that we designate at
various times. However, at our option, we may make interest payments by check
mailed to the address, as it appears in the security register, of the person
entitled to the payments. Unless we specify otherwise in the applicable
prospectus supplement, we will make payment of any installment of interest on
registered securities to the person in whose name that registered security is
registered at the close of business on the regular record date for such
interest.

   Unless we specify otherwise in the applicable prospectus supplement, the
Corporate Trust Office of the trustee, located at 425 Walnut Street, Sixth
Floor, Cincinnati, Ohio 45202, will be designated:

  .  as our sole paying agent for payments with respect to debt securities that
     are issuable solely as registered securities; and

  .  as our paying agent 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. We will name any paying agents outside the U.S. and
     any other paying agents in the U.S. initially designated by us for the
     debt securities in the applicable prospectus supplement. We 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. However, if debt securities of a series are issuable solely as
     registered securities, we will be required to maintain a paying agent in
     each place of payment for that series.

   If debt securities of a series are issuable as bearer securities, we will be
required to maintain

    .  a paying agent (a) for payments with respect to any registered
       securities of the series and (b) for payments with respect to bearer
       securities of the series in the circumstance described above, but not
       otherwise; and

    .  a paying agent in a place of payment located outside the U.S. where debt
       securities of that series and any attached coupons may be presented and
       surrendered for payment. However, if the debt securities of that series
       are listed on the London Stock Exchange, the Luxembourg Stock Exchange
       or any other stock exchange located outside the U.S. and if the stock
       exchange requires it, we will maintain a paying agent in London or
       Luxembourg or any other required city located outside the U.S. for those
       debt securities.

   All moneys we pay to a paying agent for the payment of principal, any
premium or interest on any debt security or coupon that remains unclaimed at
the end of two years after becoming due and payable will be repaid to us. After
that time, the holder of the debt security or coupon will look only to us for
payments out of those repaid amounts.

                                      8



Global Securities

   The debt securities of a series may be issued in whole or in part in the
form of one or more global certificates that we will deposit with a depositary
identified in the applicable prospectus supplement. 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 it represents, a global security may not be transferred except
as a whole:

  .  by the applicable depositary to a nominee of the depositary,

  .  by any nominee to the depositary itself or another nominee, or

  .  by the depositary or any nominee to a successor depositary or any nominee
     of the successor.

   We will describe the specific terms of the depositary arrangement with
respect to a series of debt securities in the applicable prospectus supplement.
We anticipate that the following provisions will generally apply to depositary
arrangements.

   When we issue a global security in registered form, the depositary for the
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 that global security to the accounts of persons that
have accounts with the depositary ("participants"). Those accounts will be
designated by the dealers, underwriters or agents with respect to the
underlying debt securities or by us if those debt securities are offered and
sold directly by us. Ownership of beneficial interests in a global security
will be limited to participants or persons that may hold interests through
participants. For interests of participants, ownership of beneficial interests
in the global security will be shown on records maintained by the applicable
depositary or its nominee. For interests of persons other than participants,
that ownership information will be shown on the records of participants.
Transfer of that ownership will be effected only through those records. The
laws of some states require that certain purchasers of securities take physical
delivery of securities in definitive form. These limits and laws may impair our
ability to transfer beneficial interests in a global security.

   As long as the depositary for a global security, or its nominee, is the
registered owner of that global security, the depositary or nominee will be
considered the sole owner or holder of the debt securities represented by the
global security for all purposes under the applicable indenture. Except as
provided below, owners of beneficial interests in a global security:

  .  will not be entitled to have any of the underlying debt securities
     registered in their names,

  .  will not receive or be entitled to receive physical delivery of any of the
     underlying debt securities in definitive form, and

  .  will not be considered the owners or holders under the indenture relating
     to those debt securities.

   Payments of principal of, any premium and any interest 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
registered owner of the global security representing such debt securities. None
of we, the trustee for the debt securities, any paying agent nor the registrar
for the debt securities will be responsible for any aspect of the records
relating to or payments made by the depositary or any participants on account
of beneficial interests of the global security.

   We expect that the depositary or its nominee, upon receipt of any payment of
principal, any premium or interest relating to a permanent global security
representing any series of debt securities, immediately will credit
participants' accounts with the payments. Those payments will be credited in
amounts proportional to the respective beneficial interests of the participants
in the principal amount of the global security as shown on the records of the
depositary or its nominee. We also expect that payments by participants to
owners of beneficial interests in the global security held through those
participants will be governed by standing instructions and customary practices.
This is not the case with securities held for the accounts of customers in
bearer form or registered in "street name". Those payments will be the sole
responsibility of those participants.

                                      9



   If the depositary for a series of debt securities is at any time unwilling,
unable or ineligible to continue as depositary and we do not appoint a
successor depositary within 90 days, we will issue individual debt securities
of that series in exchange for the global security or securities representing
that series. In addition, we may at any time in our sole discretion determine
not to have any debt securities of a series represented by one or more global
securities. In that event, we will issue individual debt securities of that
series in exchange for the global security or securities. Further, if we
specify, an owner of a beneficial interest in a global security may, on terms
acceptable to us, the trustee and the applicable depositary, receive individual
debt securities of that series in exchange for those beneficial interests. The
foregoing is subject to any limitations described in the applicable prospectus
supplement. In any such instance, the owner of the beneficial interest will be
entitled to physical delivery of individual debt securities equal in principal
amount to the beneficial interest and to have the debt securities registered in
its name. Those individual debt securities will be issued in denominations,
unless we specify otherwise, of $1,000 or integral multiples of $1,000.

   If we specify 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. These temporary global securities will be
deposited with a common depositary in London for Euroclear Bank S.A./N.V., as
operator of the Euroclear System and Clearstream Banking societe anonyme
(formerly known as Cedel Bank) for credit to the respective accounts of the
beneficial owners of those debt securities or to other accounts as they may
direct. On and after the exchange date determined as provided in the temporary
global security and described in the applicable prospectus supplement, each
temporary global security will be exchangeable for definitive debt securities
in bearer form, registered form, or definitive global form or any combination
of these. No bearer security including one in definitive global bearer form
delivered in exchange for a portion of a temporary global security will be
mailed or otherwise delivered to any location in the U.S. in connection with
this exchange.

   Unless we specify otherwise in the applicable prospectus supplement, we or
our agent must receive a certificate signed by Euroclear or Clearstream prior
to the delivery of a definitive bearer security. We must also receive this
signed certificate prior to the actual payment of interest on the applicable
portion of the temporary global security payable before delivery of a
definitive debt security. The certificate must be based on statements provided
to Euroclear or Clearstream by its member organizations. The certificate must
be dated on the earlier of the date of the first actual payment of interest on
the debt security or the date of delivery of the debt security in definitive
form, and must state that on that date the debt security is owned by:

  .  person that is not a U.S. person and is not a financial institution
     holding the obligation for purposes of resale during the restricted
     period;

  .  a U.S. person that is either (a) the foreign branch of a U.S. financial
     institution purchasing for its own account or for resale during the
     restricted period or (b) a U.S. person who acquired its interest through
     the foreign branch of a U.S. financial institution and who holds the
     obligation through such financial institution on the date of
     certification. In either case (a) or (b), the U.S. financial institution
     must provide a certificate stating that it agrees to comply with the
     requirements and regulations of Section 165(j)(3)(A), (B) or (C) of the
     Internal Revenue Code of 1986, as amended unless it has provided a valid
     blanket certificate stating the same; or

  .  a financial institution holding for purposes of resale during the
     restricted period. That financial institution must certify in addition
     that it has not acquired the obligation for purposes of resale directly or
     indirectly to a U.S. person or to a person within the United States or its
     possessions.

As used in this paragraph, the term "restricted period" means (a) the period
from the closing date until 40 days thereafter or (b) any time if the
obligation is held as part of an unsold allotment or subscription.

   Each of Euroclear and Clearstream will in these circumstances credit the
interest received by it to the accounts of the beneficial owners of the
temporary global security or to other accounts as they may direct.

                                      10



   The beneficial owner of a debt security underlying a definitive global
security in bearer form may exchange its interest in that definitive global
security for a definitive bearer security or securities, or a definitive
registered security or securities of any authorized denomination. The
beneficial owner must give at least 30 days' written notice of the exchange
through either Euroclear or Clearstream. No individual definitive bearer
security will be delivered in or to the U.S.

Senior Securities--Certain Restrictive Covenants

   Limitation on Liens. Other than permitted liens, which are listed below,
unless we specify otherwise in the applicable prospectus supplement, we will
not create, incur, assume or permit to exist any lien on any property that we
or any of our subsidiaries own. Liens that we are permitted to have on our
property include:

  .  any currently existing lien;

  .  easements, rights-of-way, minor defects in title, etc., that do not
     adversely affect the property or our business;

  .  liens related to taxes that are not yet due or that we are contesting in
     good faith;

  .  liens, such as mechanics liens, that arise in the ordinary course of our
     business and are being contested in good faith;

  .  pledges or deposits that evidence our commitment to perform our
     obligations;

  .  liens on equipment arising from capital leases on the equipment;

  .  pre-existing liens, or liens incurred within 45 days after acquisition, on
     property that we acquire, construct or improve;

  .  liens on office buildings or research facilities;

  .  liens that secure debt between us and a subsidiary or between two
     subsidiaries of ours;

  .  liens in favor of the United States or any political subdivision of the
     United States, or any agency or department of the United States or any
     state, to evidence our commitment to perform our obligations;

  .  any extension, renewal or replacement of any permitted lien;

  .  liens on margin stock owned by us or our subsidiaries, to the extent its
     value exceeds 25% of the value of property subject to the Limitation on
     Liens provision;

  .  liens we incur in the ordinary course of our business to secure our
     performance under performance bonds, surety bonds, etc.;

  .  statutory liens, such as rights of setoff, related to our depository
     accounts.

   In addition to the specific liens listed above, we may permit any kind of
lien to exist as long as the debt secured by those liens does not exceed 10% of
our consolidated assets for our most recently ended fiscal quarter.

   Limitations on Sale and Lease-Back. Unless we specify otherwise in the
applicable prospectus supplement, neither we nor any domestic subsidiary of
ours will enter into any arrangement with any bank or other lender or investor
to lease to us or a domestic subsidiary of ours for a period of more than three
years any real property located in the continental U.S. To be applicable, we or
a domestic subsidiary of ours must sell or plan to sell or transfer this
property to the lender or investor or to any person or organization to which
funds have been or are to be advanced by the lender or investor on the security
of the leased property. This paragraph does not apply where either: (a) we or
our domestic subsidiary would be entitled to create debt secured by a lien on
the property to be leased, without equally and ratably securing the senior
securities, or (b) we, within four months

                                      11



after the effective date of the sale and lease-back transaction, apply to the
retirement of debt of ours maturing by its terms more than one year after its
original creation, an amount equal to the greater of:

  .  the net proceeds of the sale of the real property leased pursuant to the
     arrangement, or

  .  the fair value of the real property leased at the time of entering into
     the arrangement as determined by the board of directors of Ashland.

   This amount to be applied to the retirement of debt maturing more than one
year after its creation will be reduced by an amount equal to the sum of (a)
the principal amount of debt securities delivered, within four months after the
effective date of the arrangement, to the trustee for retirement and
cancellation and (b) the principal amount of other debt maturing within one
year after its creation voluntarily retired by us within the four-month period.
The latter amount does not include retirements of senior securities and other
debt maturing within one year after its creation related to mandatory sinking
fund or prepayment provisions or by payment at maturity.

   Limitation on Consolidations and Mergers. We may not consolidate or merge
with any other person or convey or transfer all or substantially all of our
properties and assets to another person or permit another corporation to merge
into us, unless:

  .  the successor is a person organized under the laws of the United States or
     any state;

  .  the successor person, if not us, assumes our obligations on the senior
     securities and under the senior indenture; and

  .  certain other conditions are met.

Subordinated Securities

   Under the subordinated indenture, payment of the principal, interest and any
premium on the subordinated securities will generally be subordinated in right
of payment to the prior payment in full of all of our superior indebtedness.

   "Superior indebtedness" is defined as the principal of, any premium and
accrued and unpaid interest on the following items, whether outstanding on or
created, incurred or assumed after the date of execution of the subordinated
indenture:

  .  our indebtedness for money borrowed (other than the subordinated
     securities);

  .  guarantees by us of indebtedness for money borrowed of any other person;

  .  indebtedness evidenced by notes, debentures, bonds or other instruments of
     indebtedness for the payment of which we are responsible or liable, by
     guarantees or otherwise;

  .  our obligations 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, whether outstanding on the
     date of the subordinated indenture or created, incurred or assumed
     afterward; and

  .  our obligations 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 our balance sheet as a liability.

   Superior indebtedness shall also be deemed to include modifications,
renewals, extensions and refundings of any of the types of indebtedness,
liability, obligations or guarantee listed above, unless the relevant
instrument provides that such indebtedness, liability, obligation or guarantee,
or such modification, renewal, extension or refunding, is not superior in right
of payment to the subordinated securities. Superior indebtedness shall not,

                                      12



however, be deemed to include (a) any of our obligations to any subsidiary of
ours and (b) any of our indebtedness, guarantees or obligations of the type set
forth above which is subordinate or junior in ranking in any respect to any of
our other indebtedness, guarantees or obligations.

   No payment by us on account of principal of, any premium or interest on the
subordinated securities, including any sinking fund payments may be made if:

  .  any default or event of default with respect to any superior indebtedness
     occurs and is continuing and

  .  unless the default or event of default is our failure to pay principal or
     interest on any instrument constituting superior indebtedness, written
     notice of this default or event of default is given to the trustee by us
     or to us and the trustee by the holders or their representatives of at
     least 10% in principal amount of any superior indebtedness.

   We may resume payments on the subordinated securities (unless otherwise
prohibited by the related indenture) if (a) the default is cured or waived, or
(b) 120 days pass after the notice is given, if the default is not the subject
of judicial proceedings, unless the default is our failure to pay principal or
interest on any superior indebtedness.

   In the event that any subordinated security is declared due and payable
before its specified date, or upon any payment or distribution of assets by us
to creditors upon our dissolution, winding up, liquidation or reorganization,
all principal of, any premium 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. However, this does not apply to
payments received by the holders of subordinated securities consisting of
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 any holder's 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 our assets applicable to superior
indebtedness until the subordinated securities are paid in full.

   By reason of this subordination, in the event of insolvency, our creditors
who are holders of superior indebtedness, as well as certain of our general
creditors, 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 us or any of our
subsidiaries.

Modification of the Indentures
   Under each indenture our rights and obligations and the rights of the
holders may be modified with the consent of the holders of at least two-thirds
in principal amount of the then outstanding debt securities of each series
affected by the modification. However, the following modifications require the
consent of the holders of all of the affected outstanding debt securities:

  .  changing the maturity, installment or interest rate of any of the debt
     securities;

  .  reducing the principal amount, any premium or the rate of interest of any
     of the debt securities;

  .  changing the currency, currencies or currency unit or units in which any
     principal, premium or interest of any of the debt securities is payable;

  .  changing any of our obligations to maintain an office or agency in the
     places and for the purposes required by the indentures;

  .  impairing any right to take legal action for an overdue payment;

                                      13



  .  reducing the percentage required for modifications or waivers of
     compliance with the indentures; or

  .  with certain exceptions, modifying the provisions for the waiver of
     certain covenants and defaults and any of the foregoing provisions.

   Any actions we or the trustee may take toward adding to our covenants,
adding events of default or establishing the structure or terms of the debt
securities as permitted by the indentures will not require the approval of any
holder of debt securities. In addition, we or the trustee may cure ambiguities
or inconsistencies in the indentures or make other provisions without the
approval of any holder as long as no holder's interests are materially and
adversely affected.

Waiver of Certain Covenants

   The indentures provide that we will not be required to comply with certain
restrictive covenants (including those described above under "Senior
Securities--Certain Restrictive Covenants") if the holders of at least
two-thirds in principal amount of each series of outstanding debt securities
affected waive compliance with the restrictive covenants.

Events of Default, Notice and Waiver

   "Event of default" when used in an indenture, will mean any of the following
in relation to a series of debt securities:

  .  failure to pay interest on any debt security for 30 days after the
     interest becomes due;

  .  failure to pay the principal or any premium on any debt security when due;

  .  failure to deposit any sinking fund payment for 30 days after such payment
     becomes due;

  .  failure to perform or breach of any other covenant or warranty in the
     indenture that continues for 60 days after our being given notice from the
     trustee or the holders of at least 25% in principal amount of the
     outstanding debt securities of the series;

  .  certain events of bankruptcy, insolvency or reorganization of ours; or

  .  any other event of default provided for debt securities of that series.

   If any event of default relating to outstanding debt securities of any
series occurs and is continuing, either the trustee or the holders of at least
than 25% in principal amount of the outstanding debt securities of that series
may declare the principal of all of the outstanding debt securities of such
series to be due and immediately payable.
   The indentures provide that the holders of at least a majority in principal
amount of the outstanding debt securities of any series may direct the time,
method and place of conducting any proceeding for any remedy available to the
trustee, or of exercising any trust or power conferred on the trustee, with
respect to the debt securities of that series. The trustee may act in any way
that is consistent with those directions and may decline to act if any of the
directions is contrary to law or to the indentures or would involve the trustee
in personal liability.
   The indentures provide that the holders of at least a majority in principal
amount of the outstanding debt securities of any series may on behalf of the
holders of all of the outstanding debt securities of the series waive any past
default (and its consequences) under the indentures relating to the series,
except a default (a) in the payment of the principal of or any premium or
interest on any of the debt securities of the series or (b) with respect to 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 debt securities of the series affected.

                                      14



   The indentures contain provisions entitling the trustee, subject to the duty
of the trustee during an event of default to act with the required standard of
care, to be indemnified by the holders of the debt securities of the relevant
series before proceeding to exercise any right or power under the indentures at
the request of those holders.

   The indentures require the trustee to, within 90 days after the occurrence
of a default known to it with respect to any series of outstanding debt
securities, give the holders of that series notice of the default if uncured
and unwaived. However, the trustee may withhold this notice if it in good faith
determines that the withholding of this notice is in the interest of those
holders. However, the trustee may not withhold this notice in the case of a
default in payment of principal, premium, interest or sinking fund installment
with respect to any debt securities of the series. The above notice shall not
be given until at least 30 days after the occurrence of a default in the
performance of or a breach of a covenant or warranty in the applicable
indenture other than a covenant to make payment. The term "default" for the
purpose of this provision 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 that series.

   Each indenture requires us to file annually with the trustee a certificate,
executed by one of our officers, indicating whether the officer has knowledge
of any default under the indenture.

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. If the
trustee fails to call a meeting within 21 days after receipt of a request from
us or the holders of at least 10% in principal amount of the outstanding debt
securities of a series, we or the holders may call a meeting upon notice given
in accordance with the provisions described in "Notices" below. Persons
entitled to vote a majority in principal amount of the outstanding debt
securities of a series shall constitute a quorum at a meeting of the holders of
debt securities of the series. However, if any action is to be taken at the
meeting with respect to a consent or waiver which is required to be given by
the holders of at least two-thirds in principal amount of the outstanding debt
securities of a series, the persons entitled to vote two-thirds in principal
amount of the outstanding debt securities of the series will constitute a
quorum. In the absence of a quorum, a meeting called by us or the trustee shall
be adjourned for a period of at least 10 days, and in the absence of a quorum
at the adjourned meeting, the meeting shall be further adjourned for a period
of at least 10 days. Any resolution with respect to any action which may be
made, given or taken by the holders of a specified percentage in principal
amount of outstanding debt securities of a series may be adopted at a properly
reconvened meeting or adjourned meeting at which a quorum is present by the
affirmative vote of the holders of the specified percentage in principal amount
of the outstanding debt 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 debt
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 the specified percentage of outstanding debt securities of any
series affected (acting as one class), only the principal amount of outstanding
debt securities of any series represented at a meeting or adjourned meeting
duly reconvened at which a quorum is present as described above and voting in
favor of the action will be counted for purposes of calculating the aggregate
principal amount of outstanding debt securities of all series affected favoring
the 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 New York City and London and in any other cities
specified in the bearer securities. For holders of bearer securities, notices
will also be mailed to those 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 that information. Notices to holders of
registered securities will be sent by mail to the addresses of those holders as
they appear in the security register.

                                      15



Title

   Title to any bearer securities (including bearer securities in temporary or
definitive global bearer form) and any related coupons will pass by delivery.
We, the appropriate trustee and any agent of us or the 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 (whether or not such security
or coupon is overdue and notwithstanding any notice to the contrary) for the
purpose of making payment and for all other purposes.

Replacement of Securities and Coupons

   We will replace any mutilated debt security and any debt security with a
mutilated coupon at the expense of the holder upon surrender of the mutilated
debt security or debt security with a mutilated coupon to the appropriate
trustee. We will replace debt securities or coupons that are destroyed, stolen
or lost at the expense of the holder upon delivery to the appropriate trustee
of evidence of the destruction, loss or theft of the debt securities or coupons
satisfactory to us and to the trustee. In the case of any coupon which is
destroyed, stolen or lost, that coupon will be replaced upon surrender to the
appropriate trustee of the debt security with all related coupons not
destroyed, stolen or lost by issuance of a new debt security in exchange for
the debt security to which that coupon relates. In the case of a destroyed,
lost or stolen debt security or coupon, an indemnity satisfactory to the
appropriate trustee and us may be required at the expense of the holder of the
debt security or coupon before a replacement debt security will be issued.

Defeasance

   The indentures contain a provision that, if made applicable to any series of
debt securities, permits us to elect (a) to defease and be discharged from all
of our obligations (subject to limited exceptions) with respect to any series
of debt securities then outstanding, which we refer to below as "legal
defeasance", or (b) to be released from our obligations under certain
restrictive covenants (including those described above under "Senior
Securities--Certain Restrictive Covenants"), which we refer to below as
"covenant defeasance". To make either of the above elections, we must

  .  deposit in trust with the trustee (a) in the case of debt securities and
     coupons denominated in U.S. dollars, U.S. government obligations and (b)
     in the case of debt securities and coupons denominated in a foreign
     currency, foreign government securities, which through the payment of
     principal and interest in accordance with their terms will provide
     sufficient money, U.S. government obligations and/or foreign government
     obligations as necessary, without reinvestment, to repay in full those
     debt securities; and

  .  deliver to the trustee an opinion of counsel that holders of the debt
     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 (in the case of legal defeasance only, such
     opinion of counsel to be based on a ruling of the Internal Revenue Service
     or other change in applicable Federal income tax law.)

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 defined below)
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
the change in control is less than the rating on a specified earlier date by
the equivalent of at least one full rating category the following will apply.
Each holder of debt securities of that series will have the right, at the
holder's option, to require us to purchase all or any part of the holder's debt
securities on the repurchase date that is 100 days after the later of (1)
public notice of the change in control and (2) the rating decline, at 100% of
the principal amount on the repurchase date, plus accrued and unpaid interest
to the repurchase date. However, if the 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.

                                      16



   On or before the twenty-eighth day after the later of public notice of the
change in control and the decrease in the rating of the debt securities, we are
obligated to mail or cause to be mailed to all holders of record of the 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
date by which the repurchase right must be exercised, the applicable price for
the debt securities and the procedure which the holder must follow to exercise
this right. We 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 us (or an agent
designated by us for that purpose) of the holder's exercise of the right,
together with the debt security with respect to which the right is being
exercised, duly endorsed for transfer. We will comply with Rules 13e-4 and
14e-1 under the Securities Exchange Act of 1934 and any other applicable
securities laws in connection with any repurchase of debt securities.

   As used in this prospectus, a "change in control" will be deemed to have
occurred when

  .  a "person" or "group" within the meaning of Section 13(d) and 14(d)(2) of
     the Securities Exchange Act of 1934 becomes the "beneficial owner", as
     defined in Rule 13d-3 under the Act, of more than 50% of our outstanding
     voting stock, other than through a transaction consummated with the prior
     approval of the board of directors of Ashland, or

  .  during any period of two consecutive years, individuals who at the
     beginning of that period and certain directors elected subsequently who
     constitute the board of directors of Ashland cease for any reason to
     constitute a majority of the directors then in office. Additional
     directors who will be counted toward the majority include any director
     whose election by the board of directors of Ashland or whose nomination
     for election by our 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 the two-year period or whose election or nomination
     for election was previously approved.

   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 our stockholders, employees and other
creditors 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 acquiror 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 these holders. We cannot presently predict
the source of those funds, but expect that the source would be determined in
the context of the overall consideration of this type of 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

   U.S. Bank National Association is trustee under the senior indenture. The
trustee has other customary banking relationships with us and our affiliates.

                        DESCRIPTION OF PREFERRED STOCK

   General. Our Second Restated Articles of Incorporation, as amended,
authorize the board of directors of Ashland, 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
of these series. We may amend from time to time our restated articles to
increase the number of authorized

                                      17



shares of preferred stock. Any amendment like this would require the approval
of the holders of two-thirds 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, we have no preferred stock outstanding. We have
500,000 shares designated as Series A Participating Cumulative Preferred Stock
reserved for issuance upon exercise of rights under the rights agreement
described below under "Preferred Stock Purchase Rights".

   The particular terms of any series of preferred stock being offered by us
under this shelf registration will be described in the prospectus supplement
relating to that series of preferred stock. Those terms may include:

  .  the title and liquidation preference per share of the preferred stock and
     the number of shares offered;

  .  the purchase price of the preferred stock;

  .  the dividend rate (or method of calculation), the dates on which dividends
     will be paid and the date from which dividends will begin to accumulate;

  .  any redemption or sinking fund provisions of the preferred stock;

  .  any conversion provisions of the preferred stock;

  .  the voting rights, if any, of the preferred stock; and

  .  any additional dividend, liquidation, redemption, sinking fund and other
     rights, preferences, privileges, limitations and restrictions of the
     preferred stock.

   If the terms of any series of preferred stock being offered differ from the
terms set forth in this prospectus, those terms will also be disclosed in the
prospectus supplement relating to that series of preferred stock. The summary
in this prospectus is not complete. You should refer to the articles of
amendment to the restated articles establishing a particular series of
preferred stock which will be filed with the Secretary of State of the
Commonwealth of Kentucky and the SEC in connection with the offering of the
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 will be entitled to receive dividends when, as and if
declared by the board of directors of Ashland. We will pay those dividends
either in cash, shares of common stock or preferred stock or otherwise, at the
rate and on the date or dates set forth in the prospectus supplement. With
respect to each series of preferred stock, the dividends on each share of the
series will be cumulative from the date of issue of the share unless some other
date is set forth in the prospectus supplement relating to the series. Accruals
of dividends will not bear interest.

   Rights Upon Liquidation. The preferred stock will be preferred over the
common stock as to assets so that the holders of each series of preferred stock
will be entitled to be paid, upon our voluntary or involuntary liquidation,
dissolution or winding up and before any distribution is made to the holders of
common stock, the amount set forth in the applicable prospectus supplement.
However, in this case the holders of preferred stock will not be entitled to
any other or further payment. If upon any liquidation, dissolution or winding
up our net assets are insufficient to permit the payment in full of the
respective amounts to which the holders of all outstanding preferred stock are
entitled, our entire remaining net assets will be distributed among the holders
of each series of preferred stock in amounts proportional to the full amounts
to which the holders of each series are entitled.

   Redemption. All shares of any series of preferred stock will be redeemable
to the extent set forth in the prospectus supplement relating to the series.
All shares of any series of preferred stock will be convertible into shares of
common stock or into shares of any other series of preferred stock to the
extent set forth in the applicable prospectus supplement.

                                      18



   Voting Rights. Except as indicated in the prospectus supplement, the holders
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 will
vote together as one class.

   Preferred Stock Purchase Rights. On May 16, 1996, we entered into a rights
agreement with Harris Trust and Savings Bank. National City Bank is the
successor rights agent under that rights agreement, which is a shareholder
rights plan providing for a dividend of one preferred stock purchase right for
each outstanding share of our common stock. We issued the dividend to
shareholders of record on the date of the adoption of the rights agreement, and
holders of shares of common stock issued since 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 Ashland and our shareholders
against coercive takeover tactics. The purpose of the rights is to encourage
potential acquirors to negotiate with the board of directors of Ashland 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 of Ashland.

   Until a right is exercised, the holder of a right will have no rights as an
Ashland shareholder, including, without limitation, the right to vote or to
receive dividends. Upon becoming exercisable, each right will entitle its
holder to purchase from us one 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. In general, the rights will not
be exercisable until the earlier of (a) any time that we learn that a person or
group or an affiliate or associate of the person or group has acquired, or has
obtained the right to acquire, beneficial ownership of 15% or more of our
outstanding common stock, unless provisions preventing accidental triggering of
the rights apply and (b) the close of business on the date, if any, designated
by the board of directors of Ashland following the commencement of, or first
public disclosure of an intent to commence, a tender or exchange offer for 15%
or more of our outstanding common stock. Below we refer to the earlier of those
dates as the "distribution date" and the person or group acquiring at least 15%
of our common stock as an "acquiring person". You should assume that any of the
following provisions that refers to an acquiring person applies to any
associate or affiliate of the acquiring person as well.

   In the event that, following the distribution date, we are acquired in a
merger or other business combination by a publicly traded acquiring person, or
50% or more of our assets or assets representing 50% or more of our revenues or
cash flow are sold, leased, exchanged or transferred in another manner to a
publicly traded acquiring person, each right will entitle its holder to
purchase, for the purchase price, that number of common shares of the
corporation which at the time of the transaction would have a market value of
twice the purchase price. In the event we are acquired in a merger or other
business combination by a non-publicly traded acquiring person, or 50% or more
of our assets or assets representing 50% or more of our revenues or cash flow
are sold, leased, exchanged or otherwise transferred to a non-publicly traded
acquiring person, each right will entitle its holder to purchase, for the
purchase price, at the holder's option:

  .  that number of shares of the surviving corporation (including us, if we
     are the surviving corporation) in the transaction with the entity which at
     the time of the transaction would have a book value of twice the purchase
     price,

  .  that number of shares of the entity which at the time of the transaction
     would have a book value of twice the purchase price or

  .  if the entity has an affiliate which has publicly traded common shares,
     that number of common shares of the 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
will be null and void and nontransferable, and any holder of such right,
including any purported transferee or subsequent holder, will be unable to
exercise or transfer the right.

                                      19



   The rights will expire at the close of business on May 16, 2006, unless
redeemed before that time. At any time prior to the earlier of (a) the time a
person or group becomes an acquiring person and (b) the expiration date, the
board of directors of Ashland may redeem the rights in whole, but not in part,
at a price of $.01 per right. This amount is subject to adjustment as provided
in the rights agreement.

   The preceding summary is not complete and is not intended to give full
effect to provisions of statutory or common law. You should refer to the
applicable provisions of the rights agreement and the form of right
certificate, which are incorporated by reference to Exhibits 4(a) and 4(c),
respectively, to our Form 8-A, filed with the SEC on May 16, 1996, into Exhibit
4.5 to the registration statement.

   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 us and not approved by the board of directors of Ashland, it would be
possible for the board of directors of Ashland 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 us. This authority may
be limited by applicable law, the restated articles and the applicable rules of
the stock exchanges upon which the common stock is listed. The consent of the
holders of common stock would not be required for any issuance of preferred
stock like this.

   The restated articles incorporate in substance certain provisions of the
Kentucky Business Corporation Act to require certain approvals as a condition
to mergers and certain other business combinations involving us and the 10%
shareholder unless (a) the transaction is approved by a majority of our
continuing directors or (b) certain minimum price and procedural requirements
are met. Those approvals include the approval of the holders of at least 80% of
our voting stock, plus two-thirds of the voting stock other than voting stock
owned by a 10% shareholder. 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 that 10% shareholder
becomes a 10% shareholder, unless a majority of our independent directors
approves the combination before that date.

   The restated articles also provide that

  .  the board of directors of Ashland is classified into three classes,

  .  a director may be removed from office without cause only by the
     affirmative vote of the holders of at least 80% of the voting power of our
     then outstanding voting stock,

  .  the board of directors of Ashland may adopt by-laws concerning the conduct
     of, and matters considered at, meetings of shareholders, including special
     meetings,

  .  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 of our then outstanding voting stock and

  .  the by-laws may be adopted or amended by the board of directors of
     Ashland. However, the by-laws adopted in this fashion may be amended or
     repealed by affirmative vote of the holders of at least 80% of the voting
     power of our then outstanding voting stock.

                       DESCRIPTION OF DEPOSITARY SHARES

   General. We may, at our option, elect to offer fractional shares of
preferred stock, rather than full shares of preferred stock. If we exercise
this option, we will issue to the public receipts for depositary shares, and
each of these depositary shares will represent a fraction (to be set forth in
the applicable prospectus supplement) of a share of a particular series of
preferred stock.

   The shares of any series of preferred stock underlying the depositary shares
will be deposited under a deposit agreement between us and a bank or trust
company selected by us. The depositary will have its principal

                                      20



office in the United States and a combined capital and surplus of at least
$50,000,000. 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 underlying that depositary share, to all the rights
and preferences of the preferred stock underlying that depositary share. Those
rights include dividend, voting, redemption and liquidation rights.

   The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Depositary receipts will be distributed to
those persons purchasing the fractional shares of preferred stock underlying
the depositary shares, 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. The following summary of the deposit agreement,
the depositary shares and the depositary receipts is not complete. You should
refer to the forms of the deposit agreement and depositary receipts that will
be filed with the SEC in connection with the offering of the specific
depositary shares.

   Pending the preparation of definitive engraved depositary receipts, the
depositary may, upon our written order, issue temporary depositary receipts
substantially identical to the definitive depositary receipts but not in
definitive form. These temporary depositary receipts entitle their holders to
all the rights of definitive depositary receipts which are to be prepared
without unreasonable delay. Temporary depositary receipts will then be
exchangeable for definitive depositary receipts at our expense.

   Dividends and Other Distributions. The depositary will distribute all cash
dividends or other cash distributions received with respect to the preferred
stock to the record holders of depositary shares relating to the preferred
stock in proportion to the number of depositary shares owned by those holders.

   If there is a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary shares
that are entitled to receive the distribution, unless the depositary determines
that it is not feasible to make the distribution. If this occurs, the
depositary may, with our approval, sell the property and distribute the net
proceeds from the sale to the applicable 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 that 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
that series of the preferred stock. Whenever we redeem shares of preferred
stock that are 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 the notice to the record holders of the
depositary shares underlying the preferred stock. Each record holder of the
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 then
try, as far as practicable, to vote the number of shares of preferred stock
underlying those depositary shares in accordance with such instructions, and we
will agree to take all actions which may be deemed necessary by the depositary
to enable the depositary to do so. The depositary will not vote the shares of
preferred stock to the extent it does not receive specific instructions from
the holders of depositary shares underlying the 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 us and the
depositary. However, any amendment which materially and adversely alters the
rights of the holders of depositary shares will not be effective unless the
amendment has been approved by the holders of at least a

                                      21



majority of the depositary shares then outstanding. The deposit agreement may
be terminated by us or by the depositary only if (a) all outstanding depositary
shares have been redeemed or (b) there has been a final distribution of the
underlying preferred stock in connection with our liquidation, dissolution or
winding up and the preferred stock has been distributed to the holders of
depositary receipts.

   Charges of Depositary. We will pay all transfer and other taxes and
governmental charges arising solely from the existence of the depositary
arrangements. We will also 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 taxes
and governmental charges and those 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 us that we deliver to the depositary and
that we are required to furnish to the holders of the preferred stock.

   Neither we nor the depositary will be liable if either of us is prevented or
delayed by law or any circumstance beyond our control in performing our
respective obligations under the deposit agreement. Our obligations and those
of the depositary will be limited to performance in good faith of our
respective duties under the deposit agreement. Neither we nor they will be
obligated to prosecute or defend any legal proceeding in respect of any
depositary shares or preferred stock unless satisfactory indemnity is
furnished. We and the depositary 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 notice to us of its election to resign. We may remove the
depositary at any time. Any resignation or removal will take effect upon the
appointment of a successor depositary and its acceptance of the appointment.
The 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.

                          DESCRIPTION OF COMMON STOCK

   As of the date of this prospectus, we are authorized to issue up to
300,000,000 shares of common stock. As of June 30, 2001, we had 69,695,364
shares of common stock issued and outstanding and had reserved 12,094,415
additional shares of common stock for issuance under our various stock and
compensation incentive plans.

   The following summary is not complete and is not intended to give full
effect to provisions of statutory or common law. You should refer to the
applicable provisions of the following documents:

  .  the restated articles, which are incorporated by reference to Exhibit 3 to
     our Form 10-Q for the quarter ended December 31, 1997, and

  .  the by-laws, as amended, which are incorporated by reference to Exhibit
     3.2 to our Form 10-Q for the quarter ended June 30, 2001.

   Dividends. The holders of common stock are entitled to receive dividends

legally available for their payment subject to the rights of holders of the
preferred stock subject to the rights of holders of preferred stock.

   Voting Rights. The holders of common stock are entitled to one vote per
share on all matters submitted to a vote of shareholders. The holders of common
stock also possess cumulative voting rights. Under cumulative voting, a
shareholder may multiply the number of shares owned by the number of directors
to be elected and either 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.

   Rights Upon Liquidation. In the event of our voluntary or involuntary
liquidation, dissolution or winding up, the holders of common stock will be
entitled to share equally in any of our assets available for distribution after
the payment in full of all debts and distributions and after the holders of all
series of outstanding preferred stock have received their liquidation
preferences in full.

   Miscellaneous. The outstanding shares of common stock are fully paid and
nonassessable. The holders of common stock are not entitled to preemptive or
redemption rights. Shares of common stock are not convertible into shares of
any other class of capital stock. National City Bank, Chicago, Illinois, is the
transfer agent and registrar for the common stock.

                      DESCRIPTION OF SECURITIES WARRANTS

   We 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
and may be attached to or separate from any offered securities. Each series of
securities warrants will be issued under a separate warrant agreement to be
entered into between us and a bank or trust company, as warrant agent. The
securities warrant agent will act solely as our agent in connection with the
securities warrants and will not assume any obligation or relationship of
agency or trust for or with any registered holders of securities warrants or
beneficial owners of securities warrants. This summary of some provisions of
the securities warrants is not complete. You should refer to the securities
warrant agreement, including the forms of securities warrant certificate
representing the securities warrants, relating to the specific securities
warrants being offered for the complete terms of the securities warrant
agreement and the securities warrants. That securities warrant agreement,
together with the terms of securities warrant certificate and securities
warrants, will be filed with the SEC in connection with the offering of the
specific securities warrants.

   The particular terms of any issue of securities warrants will be described
in the prospectus supplement relating to the issue. Those terms may include:

  .  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 the
     debt securities may be purchased upon exercise;

  .  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;

  .  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;

  .  the date on which the right to exercise the securities warrants will
     commence and the date on which the right will expire;

  .  United States Federal income tax consequences applicable to the securities
     warrants; and

  .  any other terms of the securities warrants.

                                      23



   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 its holder to purchase the principal
amount of debt securities or the number of shares of preferred stock or common
stock at the exercise price set forth in, or calculable as set forth in, the
applicable prospectus supplement. The exercise price may be adjusted upon the
occurrence of certain events as set forth in the prospectus supplement. After
the close of business on the expiration date, unexercised securities warrants
will become void. We will specify the place or places where, and the manner in
which, securities warrants may be exercised in the applicable prospectus
supplement.

   Prior to the exercise of any securities warrants to purchase debt
securities, preferred stock or common stock, holders of the securities warrants
will not have any of the rights of holders of the debt securities, preferred
stock or common stock purchasable upon exercise, including:

  .  in the case of securities warrants for the purchase of debt securities,
     the right to receive payments of principal of, any premium or interest on
     the debt securities purchasable upon exercise or to enforce covenants in
     the applicable indenture; or

  .  in the case of securities warrants for the purchase of preferred stock or
     common stock, the right to vote or to receive any payments of dividends on
     the preferred stock or common stock purchasable upon exercise.

                             PLAN OF DISTRIBUTION

   We may sell the debt securities, preferred stock, depositary shares, common
stock or securities warrants (together referred to as the "offered securities")
(a) through underwriters or dealers; (b) directly to one or a limited number of
institutional purchasers; or (c) through agents. This prospectus or the
applicable prospectus supplement will set forth the terms of the offering of
any offered securities, including the name or names of any underwriters,
dealers or agents, the price of the offered securities and the net proceeds to
us from such sale, any underwriting commissions or other items constituting
underwriters' compensation.

   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 applicable prospectus supplement, the obligations of the
underwriters or agents 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 underwriting commissions or other items constituting
underwriters' compensation may be changed from time to time.

   If a dealer is utilized in the sale of any offered securities, we will sell
those offered securities to the dealer, as principal. The dealer may then
resell the offered securities to the public at varying prices to be determined
by the dealer at the time of resale.

   We may sell offered securities directly 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 time of sale. Unless otherwise indicated in
the prospectus supplement, any agent will be acting on a best efforts basis for
the period of its appointment.

   If an applicable prospectus supplement indicates, we will authorize agents,
underwriters or dealers to solicit offers by certain specified institutions to
purchase offered securities from us at the public offering price set forth

                                      24



in the prospectus supplement under delayed delivery contracts providing for
payment and delivery on a specified date in the future. These 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 the contracts.

   Under agreements entered into with us, agents and underwriters who
participate in the distribution of the offered securities may be entitled to
indemnification by us against certain civil liabilities, including liabilities
under the Securities Act of 1933, or to contribution with respect to payments
which the agents or underwriters may be required to make. Agents and
underwriters may be customers of, engage in transactions with or perform
services for us in the ordinary course of business.

                                 LEGAL MATTERS

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.

   (A) 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 of 1933;

          (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. Notwithstanding the foregoing, any
       increase or decrease in volume of securities offered (if the total
       dollar value of securities offered would not exceed that which was
       registered) and any deviation from the low or high end of the estimated
       maximum offering range may be reflected in the form of prospectus filed
       with the Commission pursuant to Rule 424(b) if, in the aggregate, the
       changes in volume and price represent no more than a 20% change in the
       maximum aggregate offering price set forth in the "Calculation of
       Registration Fee" table in the effective 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.

      Provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not apply
   if the information required to be included in a post-effective amendment by
   those paragraphs is contained in periodic reports filed by the Registrant
   pursuant to section 13 or section 15(d) of the Securities Exchange Act of
   1934 that are incorporated by reference in the registration statement.

      (2) That, for the purpose of determining any liability under the
   Securities Act of 1933, 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.

   (B) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 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.

   (C) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 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 Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 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 of 1933 and will be governed by the final adjudication of such
issue.

                                     II-3



   (D) The undersigned Registrant hereby undertakes that:

      (1) For purposes of determining any liability under the Securities Act of
   1933, 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.

      (2) For the purpose of determining any liability under the Securities Act
   of 1933, 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.

   (E) 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.

                                     II-4
