Ashland Signs Amended Agreement to Transfer Interest in MAP to Marathon for $3.7 Billion

COVINGTON, Ky., April 28, 2005 /PRNewswire-FirstCall via COMTEX/ -- Ashland Inc. (NYSE: ASH) today announced that it has amended its agreement to transfer its 38-percent interest in Marathon Ashland Petroleum LLC (MAP) and two other businesses to Marathon Oil Corporation (NYSE: MRO). Under the amended agreement, Ashland's interest in these businesses is valued at approximately $3.7 billion compared to approximately $3 billion in the earlier agreement, with substantially all the increase in value going directly to Ashland's shareholders in the form of Marathon stock. In addition, Marathon has agreed to pay the first $200 million of any Section 355(e) tax, if any, as compared to the prior agreement where Ashland bore full responsibility for any Section 355(e) tax. The transaction is expected to be tax free to Ashland's shareholders and tax efficient to Ashland. The two other businesses are Ashland's maleic anhydride business and 60 Valvoline Instant Oil Change (VIOC) centers in Michigan and northwest Ohio, which are valued at $94 million.

Under the terms of the amended agreement, Ashland's shareholders will receive Marathon common stock with an aggregate value of $915 million. Based on the number of shares outstanding on March 31, 2005, shareholders would receive $12.56 in Marathon stock per Ashland share. Ashland will receive cash and MAP accounts receivable totaling $2.8 billion. In addition, MAP has not made quarterly cash distributions to Ashland and Marathon since March 18, 2004, and such distributions will continue to be suspended until the closing of the transaction. As a result, the final amount of cash to be received by Ashland will be increased by an amount equal to 38 percent of the cash accumulated from operations during the period prior to closing. At March 31, 2005, Ashland's share of this accumulated cash was $560 million.

Under the terms of the earlier agreement, the closing was conditioned on receipt of private letter rulings from the Internal Revenue Service with respect to certain tax issues. Under the terms of the amended agreement, Ashland and Marathon expect to enter into a closing agreement with the IRS that will resolve these tax issues. Under the closing agreement, the retention by Ashland of certain contingent liabilities related to previously-owned businesses will reduce Ashland's tax basis. The company estimates this basis reduction may increase any Section 355(e) tax on the transaction by approximately $66 million. Marathon has agreed to pay the first $200 million of any Section 355(e) tax. Ashland would pay up to the next $175 million of Section 355(e) tax, if required. Any remaining Section 355(e) tax would be shared equally by Ashland and Marathon. Based on the number of Ashland shares outstanding as of March 31, 2005, and the company's current estimate of Ashland's tax basis, the company expects that Ashland would be required to pay Section 355(e) tax only if Ashland's stock price on the closing date exceeds approximately $74.50 per share.

Ashland intends to 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 and including the company's current estimate of MAP's final cash distribution, Ashland expects to have a net cash position of roughly $1.1 billion.

"We are pleased that our amended agreement provides an additional $700 million in value, $600 million of which will go directly to our shareholders," said James J. O'Brien, Ashland's chairman and chief executive officer. "Ashland's Board of Directors took a comprehensive look at the alternatives available to Ashland with respect to our ownership interest in MAP. We concluded that this tax efficient structure with an appropriate increase in shareholder value, as well as a significant reduction of Ashland's tax risk, was the best alternative."

Mr. O'Brien also noted that Ashland has enjoyed good working relationships with both Marathon and MAP management. "I want to thank Marathon for the successes we've shared through the MAP joint venture," said Mr. O'Brien. "We look forward to continuing our mutually beneficial business relationship as both a supplier and customer."

Mr. O'Brien added, "While Ashland has been pleased with MAP's performance, the transfer of our interest in MAP to Marathon is an important step in achieving Ashland's strategic objectives. We will have greater financial flexibility to pursue organic growth and will focus on selectively pursuing acquisitions that complement and strengthen our core businesses. I am confident that Ashland is well-positioned to create long-term value and to achieve our goal of top-quartile performance."

The transaction is subject to, among other things, approval by Ashland's shareholders, consent from public debt holders, finalization of the closing agreement with the Internal Revenue Service and customary antitrust review. Ashland and Marathon have agreed to use their reasonable best efforts to complete the transaction by June 30, 2005, with the termination date for the transaction extended to September 30, 2005.

After the close of its transaction with Marathon, Ashland will own four divisions in two Sectors -- Chemical and Transportation Construction -- both of which are focused on meeting customers' needs, enabling growth through process improvement, and achieving top-quartile performance. The Chemical Sector, which includes the Ashland Distribution, Ashland Specialty Chemical and Valvoline divisions, is creating a sustainable, low- cost business model, providing a platform for effective integration of acquisitions and driving market expansion. To enable growth, the Sector is also focusing on innovative research and the development of new products and services.

The Transportation Construction Sector, commercially known as Ashland Paving And Construction, Inc. (APAC), is executing strategies that should help it to increase its share of major projects, strengthen its marketing and business development capabilities and improve operational efficiency.

"As we integrate Ashland's businesses, we continue to find new sources of competitive advantage, creating actionable strategies with measurable targets and operating as a unified organization," O'Brien said.

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.

    Transaction Steps

Under the terms of the earlier agreement, the issuance of New Ashland Inc. common stock and Marathon common stock to Ashland's shareholders would have been accomplished through the merger (a separation merger) of HoldCo and a subsidiary of Marathon. The earlier agreement also contemplated that such issuance could occur through the distribution of New Ashland Inc. common stock by HoldCo to Ashland's shareholders followed by the issuance of Marathon common stock to Ashland's shareholders through the merger of HoldCo and a subsidiary of Marathon. To clarify the tax treatment of the transaction, the IRS has required that these issuances be accomplished through the distribution and subsequent merger rather than through a separation merger. Accordingly, under the terms of the amended agreement, 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 would redeem a portion of Ashland's 38-percent interest in MAP for
       a redemption price of approximately $900 million*, consisting of cash
       and MAP accounts receivable. Because MAP has not made quarterly cash
       distributions since March 18, 2004, this redemption price would
       increase by an amount equal to 38 percent of the cash accumulated from
       MAP's operations prior to the closing.
    2. Ashland would contribute the maleic anhydride business and 60 Valvoline
       Instant Oil Change centers to a newly formed subsidiary of Ashland
       ("HoldCo").
    3. Ashland would contribute to HoldCo its remaining interest in MAP.
    4. As a preliminary step to the final formation of New Ashland Inc.,
       Ashland would be merged with New Ashland LLC, a subsidiary of HoldCo.
       By virtue of this merger, each share of Ashland common stock would be
       converted into one share of HoldCo common stock.
    5. Marathon would arrange for a borrowing by HoldCo of $1.9 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.
    6. 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. By virtue of the merger, each New Ashland LLC membership interest
       would be converted into a number of shares of New Ashland Inc. common
       stock equal to the quotient of (1) the number of shares of HoldCo
       common stock outstanding prior to the Conversion Merger divided by (2)
       the number of New Ashland LLC membership interests outstanding prior to
       the Conversion Merger. All shares of New Ashland Inc.. common stock
       held by HoldCo immediately prior to the Conversion Merger would no
       longer be outstanding, would automatically be canceled and retired and
       would cease to exist.
    8. HoldCo would distribute shares of New Ashland Inc. common stock to the
       shareholders of Ashland (holding HoldCo shares at the effective time of
       the distribution) on the basis of one share of New Ashland Inc. common
       stock for each outstanding share of HoldCo common stock. As a result of
       the distribution, shares of New Ashland Inc. common stock will be held
       by the shareholders of Ashland common stock. New Ashland Inc. will
       receive the proceeds of the partial redemption and the capital
       contribution and own all of Ashland's existing businesses, properties
       and assets other than Ashland's interests in MAP, the maleic anhydride
       business and the 60 VIOC centers contributed to HoldCo as described
       above (#2).
    9. HoldCo would be merged into a newly formed subsidiary of Marathon,
       which would survive the merger. 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, a pro rata amount of shares of Marathon common
       stock with a total value of $915 million (based on a 20-trading day
       averaging period preceding the closing).

As provided in the earlier agreement, the transaction is conditioned on the Ashland and HoldCo Boards of Directors determination prior to closing that the distribution described in Step 8 above is in compliance with all applicable law.

* 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.
    Tax Issues

Under the terms of the earlier agreement, it was a condition to the closing of the transaction that Ashland and Marathon receive private letter rulings from the IRS with respect to certain tax issues and that Ashland and Marathon receive either private letter rulings from the IRS or opinions of counsel with respect to other tax issues. Ashland and Marathon have had extensive discussions with the IRS concerning the transaction and expect to enter into a closing agreement with the IRS that will favorably address all these tax issues with the one exception noted below. The closing agreement would be a binding agreement between Ashland, Marathon and the IRS. The closing agreement, once finalized, would satisfy the tax-related closing conditions to the transaction.

Section 355(e) of the Internal Revenue Code imposes a corporate-level tax on New Ashland Inc. to the extent that the fair market value of the stock of New Ashland Inc. on the closing date exceeds the tax basis of that stock. Under the closing agreement, the retention by Ashland of certain contingent liabilities related to previously-owned businesses (including environmental liabilities, asbestos indemnity liabilities, post-retirement benefit costs and other items) would result in a reduction of that basis, which may increase the amount of Section 355(e) tax imposed on the transaction. Ashland's current estimate of the tax basis of the stock of New Ashland Inc. after giving effect to the reduction for contingent liabilities is approximately $4 billion. The company currently estimates, based on a combined Federal and State tax rate of 39 percent and assuming the entire estimated contingent liability basis reduction results in taxable Section 355(e) gain, that the tax liability attributable to the basis reduction would be approximately $66 million.

Marathon has agreed to pay the first $200 million of all Section 355(e) tax; this $200 million amount would be increased to the extent the tax arising from the contingent liability basis reduction exceeds $75 million. Ashland would pay up to the next $175 million of Section 355(e) tax, if any. Any remaining Section 355(e) tax would be shared equally by Ashland and Marathon.

Based on Ashland's estimates, neither Ashland nor Marathon would have any Section 355(e) tax to pay unless the New Ashland Inc. stock price on the closing date exceeds approximately $55 per share, which is expected to correspond to an Ashland stock price of approximately $67.50 per share ($54.94 of New Ashland Inc. stock plus $12.56 of Marathon stock based on the numbers of shares of Ashland stock outstanding as of March 31, 2005). Ashland also estimates that it would pay Section 355(e) tax only if the New Ashland Inc. stock price on the closing date exceeds approximately $62 per share, which is expected to correspond to an Ashland stock price of approximately $74.50 per share.
