Item 8.01. Other Events Ashland Inc. ("Ashland") will hold a special meeting of shareholders on June 29, 2005 at which shareholders will be asked to approve the previously announced agreement to transfer Ashland's 38-percent interest in Marathon Ashland Petroleum LLC ("MAP") and two other businesses to Marathon Oil Corporation ("Marathon"). Approval of the transaction requires the affirmative vote of a majority of the shares of Ashland common stock outstanding and entitled to vote at the special meeting. Ashland shareholders of record as of May 12, 2005 are entitled to vote at the special meeting. On May 20, 2005, the Securities and Exchange Commission declared effective the registration statement on Form S-4 containing the proxy statement/prospectus relating to the transaction. On May 27, 2005, the definitive proxy statement/prospectus was mailed to Ashland shareholders entitled to vote at the special meeting. The special meeting will be held at 10:30 a.m. (EDT) on June 29, 2005 at the Metropolitan Club, 50 E. RiverCenter Boulevard, Covington, Kentucky. The transaction is subject to, among other things, approval by Ashland's shareholders and consent from public debt holders. Ashland and Marathon continue to expect to close the transaction on June 30, 2005. In addition, on May 31, 2005, MAP made a pro rata cash distribution to Ashland and Marathon, with Ashland's share being approximately $268 million. As previously disclosed, Ashland and Marathon have agreed that MAP will not make its quarterly distributions for the period from March 18, 2004 (the date of the signing of the original master agreement relating to the transaction) to the closing of the transaction or the termination of the master agreement, unless approved by a supermajority vote of the MAP board of managers. The MAP board of managers approved the pro rata cash distribution on May 27, 2005.
