ASHLAND INC. AGREES TO TRANSFER INTEREST IN MAP TO
MARATHON OIL CORPORATION IN TAX-FREE TRANSACTION

COMPANY PROVIDES UPDATE ON CORE BUSINESSES

Covington, Ky. - Ashland Inc. (NYSE: ASH) today announced that it has signed
an agreement under which Ashland will transfer its 38 percent interest in
Marathon Ashland Petroleum LLC (MAP) and two other businesses to Marathon Oil
Corporation in a transaction structured to be 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 (VIOC) centers in
Michigan and northwest Ohio, which are valued at $94 million.

     Under the terms of the agreement, Ashland's shareholders would receive
Marathon common stock with a value of $315 million (or approximately $4.50 per
Ashland share based on the number of shares currently outstanding). Ashland
would receive cash and MAP accounts receivable totaling $2.7 billion. MAP will
not make quarterly cash distributions to Ashland and Marathon between now and
the closing of the transaction. As a result, the final amount received by
Ashland would be increased






by an amount equal to 38 percent of the cash accumulated from operations
during the period prior to closing. Ashland would use a substantial portion of
the transaction proceeds to retire all or most of the company's outstanding
debt and certain other financial obligations. After payment of these
obligations, Ashland would have a material net cash position.

     The transaction is subject to, among other things, approval by Ashland's
shareholders, customary antitrust review, consent from public debt holders and
receipt of a favorable private letter ruling from the Internal Revenue Service
with respect to the tax treatment of the transaction. There is meaningful risk
that the transaction will not receive the favorable ruling from the IRS, in
which case the transaction would not proceed. However, Ashland believes it is
more likely than not that this transaction will receive a favorable ruling. If
these conditions are met, the transaction is expected to close by the end of
the 2004 calendar year.

     "This transaction represents the best opportunity for Ashland and its
shareholders to capture the value that has been created through this joint
venture," said James J. O'Brien, Ashland's chairman and chief executive
officer. "While we have been pleased with both the performance of the joint
venture and our relationship with Marathon, the transfer of our interest in
MAP to Marathon is an important step in achieving our strategic objectives."

     In connection with the transaction, Credit Suisse First Boston LLC acted
as financial advisor, and Cravath, Swaine & Moore LLP acted as legal counsel
to Ashland.

BUSINESS UPDATE

     The improved performance of Ashland's wholly-owned divisions in the first
quarter continued into the second quarter of fiscal 2004.

     Ashland's Transportation Construction sector (Ashland Paving And
Construction, Inc., or "APAC(R)") anticipates improved performance for the
quarter ending March 2004, although its results for the quarter reflect
seasonal winter weakness. APAC is expecting a loss in the range of $30 million
to $40 million compared to the $57 million loss for the March 2003 quarter.
Going forward, APAC will focus on improving its performance in the near term
and in the longer-term on major project capabilities and expanding both


                                      2





within and adjacent to its current geographic markets. Ashland believes that
APAC is well-positioned to benefit from the expanded highways spending
legislation that is currently under Congressional review.

     Ashland's Chemicals sector includes Ashland Distribution, Ashland
Specialty Chemical (thermoset resins and water technologies businesses) and
Valvoline. These divisions remain focused on creating innovative products and
solutions, maintaining a low cost structure and expanding their markets. The
Chemicals sector continues to perform well and anticipates operating income
for the March quarter in the range of $50 million to $55 million, compared to
$30 million in the March quarter of last year.

     Each division within the Chemicals sector expects increased operating
income for the March quarter, with the largest improvements projected by
Ashland Distribution and Ashland Specialty Chemical. Ashland Distribution's
growth has been driven by consistent sales volume increases. Ashland Specialty
Chemical's growth is due in part to new product introductions, such as new
additions to the MAXGUARD(R) marble clear gel coat and POLARIS(R) resin lines.
These products enable Ashland to work proactively with manufacturers to
optimize their entire cast marble, onyx or solid surface fabrication
processes. Valvoline's momentum is built on its successful premium products
strategy, and the division continues to introduce new, customer-focused
products and services, contributing to its consistent top-line growth. For
example, VIOC - which owns and franchises more than 740 stores nationwide -
recently launched a fleet management program that incorporates both VIOC and
other vendors' maintenance records into a comprehensive service history.

     "Much of the progress we have made in the past year is due to the hard
work and dedication of our employees," said Mr. O'Brien. "I would like to
thank them for their continuing effort as we focus on the execution of our
strategies.

     "Our disciplined investment approach will focus on expanding and
strengthening our core businesses through organic growth," continued Mr.
O'Brien. "We have already made significant progress in improving our core
operations, and I am confident that Ashland is well-positioned to create
long-term value in our wholly owned divisions and to achieve our goal of
top-quartile performance."

APPENDIX:

ASHLAND INC. TO TRANSFER INTEREST IN MAP TO MARATHON OIL CORPORATION


TRANSACTION STEPS

     The transaction would be accomplished through a series of steps, which
would all occur on the day of closing and in the following order:

1.   MAP Partial Redemption. MAP would redeem a portion of Ashland's 38%
     interest in MAP for a redemption price likely to be in the range of $900
     million*, consisting of cash and MAP accounts receivable. Because MAP
     will not make quarterly cash distributions prior to the closing, such
     redemption price would increase by an amount equal to 38% of the cash
     accumulated from MAP's operations prior to closing.

2.   Maleic/VIOC Contribution. Ashland would contribute the maleic anhydride
     business and 61 Valvoline Instant Oil Change centers to a newly formed
     subsidiary of Ashland ("HoldCo").

3.   MAP Contribution. Ashland would contribute to HoldCo its remaining
     interest in MAP.

4.   The Reorganization Merger. As a preliminary step to the final formation
     of New Ashland Inc., Ashland would be merged with and into New Ashland
     LLC, which would be the surviving business entity of that merger and a
     subsidiary of HoldCo.

          o    By virtue of this Reorganization Merger, each share of Ashland
               common stock would be converted into and represent one share of
               HoldCo common stock.


                                      5





5.   HoldCo Borrowing and Capital Contribution. Marathon would arrange for a
     borrowing by HoldCo of $1.8 billion*, which would be expressly
     non-recourse to New Ashland LLC and would otherwise be made on terms and
     conditions reasonably acceptable to Ashland. HoldCo would contribute to
     New Ashland LLC the proceeds of the borrowing.

          o    The amount of the HoldCo borrowing would depend on the amount
               of Ashland financings outstanding at closing that the Internal
               Revenue Service would permit Ashland to pay down with the
               proceeds of the borrowing. If the amount of this borrowing is
               increased (or decreased), the amount of the partial redemption
               would be decreased (or increased) accordingly.

6.   The Conversion Merger. New Ashland LLC would be merged with and into New
     Ashland Inc., which would survive the merger. New Ashland Inc. would be a
     wholly owned subsidiary of HoldCo.

7.   Separation and Merger. HoldCo would be merged into a newly formed
     subsidiary of Marathon, which would survive the merger.

          o    By virtue of the merger of HoldCo and the Marathon subsidiary,
               the former Ashland shareholders (now holding HoldCo shares)
               would have the right to receive, for each share of HoldCo
               common stock, (1) one share of New Ashland Inc. common stock
               and (2) a pro rata amount of shares of Marathon common stock
               with a total value of $315 million (based on a 20-trading day
               averaging period preceding the closing).

          o    For tax purposes, this merger will be treated as a spin-off of
               New Ashland to shareholders followed by the merger of HoldCo
               into the Marathon subsidiary.

*  Note - The separate amounts received from MAP and HoldCo could vary from
   these stated amounts, but in any event, the combination would equal
   approximately $2.7 billion.


                                      6






TAX ISSUES

The receipt of the following favorable rulings from the IRS is a condition to
closing:

1.   The form of the transaction will be respected as a redemption, followed
     by a tax-free spin-off and merger.

2.   The assumption of HoldCo borrowing by Marathon will not be taxable to New
     Ashland.

3.   Either New Ashland or Marathon will be entitled to tax deductions for
     future payments of Ashland's liabilities associated with discontinued
     business operations, including asbestos, environmental, post-retirement
     benefits, and other items.

4.   The tax basis in New Ashland will not be reduced by the assumption of
     liabilities associated with discontinued business operations in a way
     that would cause additional taxable Section 355(e) gain to be recognized
     by Ashland.*


There are other tax issues on which the transaction would proceed on the basis
of opinions from outside tax counsel, Cravath, Swaine & Moore LLP.


*  Note - Although Ashland expects the transaction to be tax free to Ashland
   and its shareholders, a tax under Internal Revenue Code Section 355(e)
   would be imposed on Ashland if the market value of New Ashland at closing
   exceeds the tax basis in New Ashland. That tax basis will change between
   the date of signing and the date of closing based on a number of factors,
   including results from operations of Ashland's wholly owned divisions and
   the accumulated amount of foregone MAP distributions. Based on current
   estimates, Ashland would begin paying taxes to the extent the Ashland stock
   price at closing exceeds $55.50 based on the number of Ashland shares
   currently outstanding. This $55.50 includes $4.50 in value for the Marathon
   stock that would be issued to Ashland's shareholders. Any taxes paid would
   likely be modest compared to the size of the transaction.
