ASHLAND INC.  ANNOUNCES  CASH TENDER OFFERS AND CONSENT  SOLICITATIONS
FOR $1,149,130,000 OF ITS NOTES AND DEBENTURES

COVINGTON,  Ky.- Ashland Inc. (NYSE: ASH) ("Ashland")  announced today that
it is  commencing  tender  offers  to  purchase  for  cash  any and all the
following  outstanding Notes (having the CUSIP Nos.  specified in the table
below):  6.625% Senior Notes, 8.80% Debentures,  9.35% Series B Medium-Term
Notes, 9.20% Series D Medium-Term Notes, Series E Medium-Term Notes, Series
F Medium-Term Notes, Series G Medium-Term Notes, 6.86% Series H Medium-Term
Notes and 7.83% Series J Medium-Term Notes (collectively, the "Notes"). The
above Notes and Debentures have maturities ranging from 2005 to 2025.
         Ashland is making the tender offers and consent  solicitations  in
connection with a series of transactions  that, among other things,  effect
the transfer of its interest in Marathon Ashland Petroleum LLC ("MAP"), its
maleic  anhydride  business  and 60 Valvoline  Instant Oil Change  ("VIOC")
centers in Michigan  and  northwest  Ohio to a wholly owned  subsidiary  of
Marathon Oil Corporation ("Marathon").  In the course of these transactions
Ashland will merge with and into one of its  subsidiaries,  which will then
merge into a successor  company,  as more fully  described  in the Offer to
Purchase and Consent  Solicitation  Statement  (such series of transactions
are referred to collectively as the "Proposed Transaction").
         In conjunction with the tender offers,  Ashland is also soliciting
consents  from  holders  of each  series  of Notes to  eliminate  or modify
substantially all of the restrictive  covenants,  certain events of default
and certain additional  covenants and rights in the Notes and the Indenture
related to each series of Notes (the "Proposed Amendments"). Holders cannot
tender their Notes without  delivering  their consent and cannot  deliver a
consent  without  tendering  their Notes.  It is expected that the Proposed
Amendments  with  respect to a series of Notes will,  if  approved,  become
effective  prior to consummation  of the Proposed  Transaction,  subject to
prior or subsequent acceptance of tenders pursuant to the applicable tender
offer.

ASHLAND INC.  ANNOUNCES  CASH TENDER OFFERS AND CONSENT  SOLICITATIONS
FOR $1,149,130,000 OF ITS NOTES AND DEBENTURES - 2

         The tender  offers and consent  solicitations  are being made upon
the terms and subject to the conditions in an Offer to Purchase and Consent
Solicitation  Statement and related Letter of Transmittal and Consent dated
June 1, 2005.  Each of the tender offers will expire at 5:00 p.m., New York
time, on June 29, 2005,  unless  extended at the sole discretion of Ashland
(such date and time, as it may be extended, the "Expiration Date"). Holders
of the Notes must  tender  their  Notes and  deliver  their  consent to the
Proposed  Amendments  at or prior to 5:00 p.m.,  New York time, on June 15,
2005,  unless  extended  by  Ashland  (such  date  and  time,  as it may be
extended,  the "Consent  Payment  Deadline")  in order to receive the Total
Purchase Price (defined below), which includes the Consent Payment (defined
below). Notes tendered may not be withdrawn,  and consents given may not be
revoked, unless the applicable tender offer is terminated without any Notes
being purchased.
         The  "Total  Purchase  Price"  Ashland  will pay for  each  $1,000
principal amount of Notes validly tendered prior to the applicable  Consent
Payment  Deadline  and  accepted by Ashland for payment  will be the "fixed
spread price" for such Notes  calculated in accordance with standard market
practice as  described  in the Offer to Purchase  and Consent  Solicitation
Statement,  representing  a present  value  calculation  of future  payment
obligations  in respect of such Notes after the  Settlement  Date  (defined
below),  using a  discount  rate  equal  to the sum of:  (i) the  yield  to
maturity (the "reference  yield") on the applicable U.S.  Treasury Security
(the "reference  security") listed on the table below for such Notes and as
calculated  by Credit  Suisse First  Boston LLC (the  "Dealer  Manager") in
accordance with standard market  practice,  based on the bid-side price for
such  reference  security,   as  indicated  on  the  applicable   Bloomberg
Government  Pricing  Monitor  screen  listed  on the  table  below for such
reference  security (or such other recognized  quotation source selected by
the  Dealer  Manager in its sole  discretion  if the  Bloomberg  Government
Pricing  Monitor is not  available or is  manifestly  erroneous) as of 2:00
p.m.,  New York time,  on the  second  business  day before the  applicable
Expiration Date (such date the "price  determination  date"); plus (ii) the
applicable  fixed  spread  for such  Notes  listed on the table  below (the
"fixed spread price").
         With  respect  to each  series  of  Notes,  the  applicable  Total
Purchase Price includes the applicable  Consent  Payment,  equal to $20 for
each  $1,000  principal  of those  Notes  validly  tendered  and  accepted.
Noteholders  tendering  Notes pursuant to the applicable  tender offer will
not receive the applicable  Consent  Payment unless their Notes are validly
tendered at or prior to the applicable  Consent  Payment  Deadline and such
tender offer is subsequently  consummated.  If a noteholder validly tenders
their Notes pursuant to the applicable tender offer after the applicable
                                  - MORE -

Consent Payment  Deadline,  and the applicable tender offer is consummated,
the noteholder  will be paid only the Total Purchase Price less the Consent
Payment (the "Purchase Price") even if the Proposed Amendments are adopted.
In order for the tender offer and consent  solicitation  for a series to be
effective,  registered holders of not less than 66?% in aggregate principal
amount of the Notes of that series  must tender  their Notes and such Notes
must not mature on or prior to the  applicable  Expiration  Date. For these
purposes, all of the Notes outstanding in a series are treated as part of a
single series.
         As soon as  practicable  after  2:00 p.m.,  New York time,  on the
applicable  price  determination  date,  but in any event at or before 9:00
a.m., New York time, on the following  business day,  Ashland will publicly
announce the reference  yields and Total Purchase Prices for each series of
Notes, and for the securities  within each series,  by press release to the
Dow Jones New Service.
         Ashland  will  pay for  Notes  purchased  promptly  following  the
Expiration  Date of the  applicable  tender  offer  (each  such  date,  the
"Settlement  Date").  In  addition,  Ashland  will pay  accrued  and unpaid
interest on  tendered  and  accepted  Notes up to, but not  including,  the
Settlement Date.
         Each tender offer and consent solicitation for a particular series
of Notes is separate  from each tender offer and consent  solicitation  for
other series of Notes.  Ashland reserves the right to extend,  amend, waive
the conditions to, or terminate each tender offer and consent solicitation.
         Ashland's  obligation  to accept,  and pay for,  Notes of a series
validly  tendered  pursuant  to a  tender  offer  is  conditioned  upon the
satisfaction or waiver of various conditions, including: (a) the receipt of
valid consents to the Proposed  Amendments from  registered  holders of not
less than 66?% in aggregate
               principal amount of the Notes of such series;
(b) such series of Notes not having  matured on or prior to the  applicable
Expiration  Date; (c)  consummation  of the Proposed  Transaction;  and (d)
satisfaction of general conditions.
         Cede & Co., the nominee of The Depositary  Trust Company  ("DTC"),
is the  registered  holder of all the Notes  subject to the tender  offers.
Beneficial  holders  wishing  to  tender  their  notes  must  instruct  the
participant  in DTC through which they hold such Notes to tender such Notes
on their behalf.
