         Section 8- Other Events
         Item  8.01 Other Events

         On December 23, 2005, Leucadia National Corporation issued the
following press release announcing that it had completed the previously
announced sale of WilTel Communications Group, LLC to Level 3 Communications,
Inc.:

                          LEUCADIA NATIONAL CORPORATION
               COMPLETES SALE OF WILTEL COMMUNICATIONS GROUP, LLC
                         TO LEVEL 3 COMMUNICATIONS, INC.


New York, New York . . . December 23, 2005, Leucadia National Corporation (NYSE:
"LUK") today announced the completion of the sale of its telecommunications
subsidiary, WilTel Communications Group, LLC, to Level 3 Communications, Inc.
for aggregate consideration consisting of $486 million in cash (including $16
million for excess working capital, which is subject to adjustment, and $100
million in cash to reflect that amount of cash left in WilTel), and 115 million
newly issued shares of Level 3 common stock, having an aggregate market value of
$339 million (based on the $2.95 per share closing price of Level 3 common stock
on December 22, 2005). Leucadia expects to report a pre-tax gain on the sale of
approximately $180 million and will classify WilTel as a discontinued operation
during the fourth quarter of 2005.

In connection with the sale, Leucadia retained those assets and liabilities of
WilTel that were not purchased by Level 3. The retained assets include (i)
WilTel's headquarters building located in Tulsa, Oklahoma, (ii) WilTel's cash
and cash equivalents in excess of $100 million, and (iii) WilTel's marketable
securities. In addition, Leucadia retained all of WilTel's right to receive cash
payments from SBC Communications Inc. totaling $236 million pursuant to the
previously announced Termination, Mutual Release and Settlement Agreement dated
June 15, 2005 among the Company, WilTel and SBC. Prior to the closing, WilTel
repaid its long-term debt obligations using its funds, together with funds
advanced by Leucadia. In addition, the retained liabilities include WilTel's
defined benefit pension plan and supplemental retirement plan obligation and
certain other employee related liabilities and other claims. The net value of
these retained assets and retained liabilities has not yet been determined.

The agreement with Level 3 requires that all parties make the appropriate
filings to treat the purchase of WilTel's membership interests as a purchase of
assets for federal, state and local income and franchise tax purposes. As a
result, WilTel's operating loss carryforwards, including any tax loss
carryforwards generated by the sale, will remain with Leucadia. Leucadia
currently estimates that after the closing it has federal net operating loss
carryforwards of approximately $4.9 billion, which are subject to
qualifications, limitations and uncertainties as discussed in Leucadia's Annual
Report on Form 10-K for the year ended December 31, 2004.


                                       2

Leucadia' remaining telecommunications operations are conducted through ATX
Communications, Inc., an integrated communications provider that offers local
exchange carrier and inter-exchange carrier telephone, Internet, high-speed data
and other communications services to business and residential customers in
certain markets throughout the Mid-Atlantic and Midwest regions of the United
States.
