Filed by Ashland Inc. pursuant to Rules 165 and 425 promulgated under the Securities Act of 1933, as amended, and deemed filed pursuant to Rule 14a-12 promulgated under the Securities Exchange Act of 1934, as amended. Subject Company: Ashland Inc. Commission File No.: 001-02918 FOR FURTHER INFORMATION: Media Relations: Investor Relations: Alan Chapple Bill Henderson (770) 392-5352 (859) 815-4454 alchapple@ashland.com wehenderson@ashland.com FOR IMMEDIATE RELEASE MARCH 19, 2004 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." 3 ANALYST/INVESTOR TELECONFERENCE INFORMATION Today at 10:00 a.m. Eastern Time, Ashland will provide a live audio webcast of its teleconference with securities analysts.

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. 7
