press release, which is attached as Exhibit 99.1 to, and incorporated by

Ark Land Company's Divestiture of Certain Interests in NRP

     On December 22, 2003, Arch Coal, Inc. and Ark Land Company sold the
following interests:

         o   all of their interests in GP Natural Resource Partners LLC, the
             general partner of NRP's general partner, to Robertson Coal
             Management LLC;
         o   all of their interests in NRP (GP) LP, NRP's general partner,
             together with all of its incentive distribution rights, to NRP
             Investment L.P, an affiliate of the original sponsors of NRP; and
         o   4,796,920 subordinated units of Natural Resource Partners L.P. to
             FRC-WPP NRP Investment L.P., an affiliate of the original sponsors
             and First Reserve Corporation.

     Arch retained the right to elect two directors to the board of directors of
GP Natural Resource Partners LLC for so long as Arch continues to hold at least
10% of the common units of Natural Resource Partners. In connection with the
sale, the board of directors of GP Natural Resource Partners LLC was expanded to
nine members, and FRC-WPP Investment L.P., which is indirectly controlled by
First Reserve Corporation, obtained the right to elect two directors, one of
whom must be an independent director, to the board. Immediately upon the
closing, First Reserve nominated Alex T. Krueger to fill one of the director
positions. NRP issued a press release relating to the disposition of the Arch
interests, which is attached as Exhibit 99.2 to, and incorporated by reference
in, this Form 8-K.
