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 March 19, 2004 Dear Ashland Associates, Earlier today, we announced in a news release that Ashland has signed an agreement under which Ashland will transfer its 38 percent interest in 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 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. The transaction is subject to, among other things, approval by Ashland shareholders, customary antitrust review, consent from public debt holders and receipt of a favorable private letter ruling from the IRS 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, we believe 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. If concluded successfully, this transaction will eliminate the uncertainty around the future of our ownership interest in MAP. The transfer of our interest in MAP fits our strategy of transforming the fundamental performance and financial dynamics of Ashland. POSITIONING ASHLAND FOR THE FUTURE I view the events of today as another step toward accomplishing the goals I established in October 2002, through my eight-point profitability improvement plan. We have been successful because we have worked hard, we have worked as a team, and we have tried to uncover new and better ways of running our businesses. We have much to be proud of: o Through our Top-Quartile Cost Structure program, we have worked to reduce certain selling, general and administrative costs down by a rate of $100 million in 2004. o In an effort to improve returns, Ashland Distribution has restructured nearly everything about its operations, improving sales revenues by 11 percent in 2003, and they continue to grow. o Our Ashland Paving And Construction division has improved it results significantly during the first quarter of this fiscal year, and we expect our restructuring and cost-reduction efforts will have a continued, positive effect on the division's performance. o To improve organizational effectiveness, we have implemented a process- centered approach to how we operate. Last month, we introduced our new, unified business platform, which positions our four wholly-owned divisions into two primary cores: Chemicals and Transportation Construction. o We have a continuing process to review our portfolio and optimize our business mix. This resulted in the sale of our Electronic Chemicals business in 2003, which is a great business but one we felt would generate more value to our shareholders if it was monetized. o Since 2002, we have reduced total debt by $233 million and increased cash by $111 million. o When the profitability improvement plan was announced, I shared our strategy to expand in existing or adjacent markets. The changes that we have made in the past year have positioned us well for the future. o And finally, we promised to capture value from MAP. Since that time, we have dedicated substantial resources to this matter, and we believe this transaction provides the highest value for Ashland and our shareholders. MAINTAINING OUR FOCUS I would imagine that everyone has many questions on their minds right now, some of which we may not be able to answer right away. Here are three top-of-mind questions that have been on my mind and that I'd like to answer for you now: FIRST, WHAT WILL WE DO WITH ALL THAT MONEY? The primary use of the proceeds from this transaction would be to reduce debt. It is not our intent to use the proceeds to repurchase stock or pay a special dividend. We will remain very disciplined and patient in our investment approach. We will not relax our standards just because we find ourselves with a large amount of cash and little or no debt. The central focus of our reinvestment strategy will be on organic growth in our core businesses. SECOND, WHAT WILL HAPPEN TO OUR COLLEAGUES WHO WILL BECOME MEMBERS OF MARATHON UPON CLOSING OF THE TRANSACTION? First, it is Marathon's intent to employ all active employees in both operations once the transaction is complete. In addition, we expect our very productive relationships with MAP and Marathon to continue and, in fact, to grow. MAP is currently a supplier to our Valvoline, APAC and chemical distribution divisions, selling us lube stocks, asphalt and solvents. MAP is also a customer for packaged products from Valvoline and water treatment chemicals provided by our Specialty Chemical division. And finally, MAP would become the sole supplier of maleic anhydride for our domestic unsaturated polyester resin business and would become our largest VIOC franchisee. THIRD, ARE WE READY FOR THIS? While preparation is 80 percent of the game, it's execution that puts points on the scoreboard. We have spent the past 17 months studying the competition, learning our real strengths, and planning how to succeed. We have re-written our playbook. Now we are ready to take action - to execute! Flexibility and speed will be key to our success. I know we have what it takes to win. When Ashland wins, our whole team wins. This is our time, and I believe we're ready. So, let's execute, and let's do it as one unbeatable Ashland team.
