<footnote id="F1">On October 17, 2002, Ark Land Company, in connection with the initial public offering of the Issuer, contributed to the Issuer its equity interest as an affiliated entity of the Issuer in exchange for Common and Subordinated Units.</footnote>
<footnote id="F2">These units were initially reported in Table I.  However, Arch has reevaluated the nature of the subordinated units and now believes them to be derivative securities reportable in Table II.</footnote>
<footnote id="F3">The subordination period will end once certain financial tests in the partership agreement are met, but it generally cannot end before September 30, 2007.  If certain financial tests in the partnership agreement are met for any quarter ending on or after September 30, 2005, 25% of the subordinated units will convert into common units.  If certain financial tests are met for any quarter ending on or after September 30, 2006, an additional 25% of the subordinated units will convert into common units.</footnote>
<footnote id="F4">Not Applicable.</footnote>
