Item 5.    Other Events.
           ------------

           On August 21, 2003, Leucadia National Corporation ("Leucadia") and
WilTel Communications Group, Inc. ("WilTel") issued a joint press release
announcing board approval and execution of an Agreement and Plan of Merger
providing for the merger of a subsidiary of Leucadia into WilTel, with WilTel as
the surviving corporation.

           Under the terms of the merger agreement, Leucadia will first commence
an exchange offer in which tendering WilTel stockholders will receive 0.4242 of
a Leucadia common share and one contingent sale right for each share of WilTel
common stock tendered in the offer. The exchange offer, if consummated, will be
followed by a back-end merger for the same consideration as offered in the
exchange offer. In general, the contingent sale rights give WilTel stockholders
the opportunity to receive additional Leucadia common shares if Leucadia sells
substantially all of WilTel's assets or outstanding shares of capital stock
prior to October 15, 2004 (which Leucadia has no plans to do) and the net
proceeds from such sale exceeds the valuation in this transaction accorded to
WilTel's equity.

           Consummation of the transaction is subject to the condition that
there be validly tendered (and not withdrawn) at least a majority of the shares
of WilTel's outstanding common stock not owned by Leucadia, receipt of certain
regulatory approvals and other customary conditions. A copy of the Agreement and
Plan of Merger and the press release are attached hereto as Exhibits 2.1 and
99.1, respectively, and are incorporated herein by reference.
