Item 4.  Purpose of Transaction
- ------   ----------------------
    	On June 22, 1999, Ashland, as a shareholder of Arch Coal, announced that
it had retained the investment banking firm of Goldman Sachs to help
Ashland explore strategic alternatives for its investment in Arch Coal.  On
October 5, 1999, Ashland announced that it was making progress on its
study to explore strategic alternatives for its investment in Arch Coal
and that, at this point, a tax-free spin-off to its shareholders would
seem to be its preferred alternative.  Ashland also announced that it has
submitted a proposal to Arch Coal and has begun discussions with a
special committee of the Arch Coal Board of Directors regarding such a
spin-off transaction.  Such a spin-off would be subject, among other things,
to a negotiated agreement with the special committee of the Arch Coal
Board of Directors, approval by the Arch Coal shareholders, a favorable
ruling from the Internal Revenue Service, and approval by Ashland's
Board of Directors. There can be no assurance that an agreement with the
special committee of the Arch Coal Board of Directors will be reached
or that the necessary approvals of the Arch Coal shareholders and the
Ashland Board of Directors will be obtained or that a favorable ruling
from the Internal Reveue Service will be obtained.  Even if an agreement
is reached and such conditions are met, Ashland anticipates that it will
be several months before a spin-off could be consummated.
    	Any strategic alternatives, including a spin-off, may result in (a) the
acquisition by any person of additional securities of Arch Coal, or the
disposition of securities of Arch Coal; (b) an extraordinary corporate
transaction, such as a merger, reorganization or liquidation, involving Arch
Coal or any of its subsidiaries; (c) a sale or transfer of a material amount
of assets of Arch Coal or any of its subsidiaries; (d) a change in the present
board of directors or management of Arch Coal, including any plans or
proposals to change the number or term of directors or to fill any existing
vacancies on the board; (e) a material change in the present capitalization or
dividend policy of Arch Coal; (f) a material change in Arch Coal's business or
corporate structure; (g) changes in Arch Coal's charter, bylaws or instruments
corresponding thereto or other actions which may impede the acquisition of
control of Arch Coal by any person; (h) a class of securities of Arch Coal to
be delisted from a national securities exchange or ceasing to be authorized to
be quoted in an inter-dealer quotation system of a registered national
securities association; (i) the common stock of Arch Coal becoming eligible
for termination of registration pursuant to Section 12(g)(4) of the Securities
Exchange Act; or (j) any action similar to the foregoing.
