ASHLAND INC. PROVIDES UPDATE ON ITS
AGREEMENT TO TRANSFER ITS INTEREST IN
MAP TO MARATHON OIL CORPORATION

COVINGTON,  Ky. - In its  fiscal  2004 Form  10-K,  which was filed  today,
Ashland Inc. stated that it continues to discuss with the Internal  Revenue
Service (IRS) the complex tax issues  related to its  previously  disclosed
agreement to transfer its interest in Marathon Ashland  Petroleum LLC (MAP)
to Marathon Oil Corporation.
     On March 19, 2004, Ashland announced the signing of an agreement under
which it would transfer its 38-percent interest in MAP and two wholly-owned
businesses to Marathon in a transaction structured to be generally tax free
and valued at  approximately  $3.0 billion.  The two other  businesses  are
Ashland's  maleic  anhydride  business and 61 Valvoline  Instant Oil Change
centers.  The  transaction  is  subject  to  several  previously  disclosed
conditions,  including  approval by  Ashland's  shareholders,  consent from
Ashland's  public debt  holders and receipt of a favorable  private  letter
ruling from the IRS with respect to the tax  treatment of the  transaction.
Ashland has filed registration  statements and proxy materials with the SEC
and is responding to comments. In addition,  Ashland submitted a request to
the IRS for a private letter ruling on the tax-free  status of the proposed
transaction. Ashland continues to discuss the complex tax issues related to
this transaction with the IRS. Ashland has not resolved all issues with the
IRS and is exploring  alternatives  for the resolution of these issues.  At
this time,  Ashland  cannot predict  whether the requested  rulings will be
received. If the requested rulings

                                  -more-


are not received,  the transaction would have to be modified or terminated.
In any  event,  Ashland  does not  believe  that a  transaction  will close
earlier than March 2005.

chemical and petroleum  company providing  products,  services and customer
