Item 1.              Security and Issuer.
                     -------------------

                     This Statement constitutes Amendment No. 2 ("Amendment No.
2") to the statement on Schedule 13D (the "Original 13D") filed with the
Securities and Exchange Commission by Leucadia National Corporation
("Leucadia"), and its subsidiaries, LUK Acquisition I, LLC ("LUK I") and LUK
Acquisition II, LLC ("LUK II"), with respect to the common stock, $0.01 par
value per share (the "WilTel Common Stock"), of WilTel Communications Group,
Inc., a Nevada corporation ("WilTel").

                     Unless otherwise indicated, all capitalized terms used
herein have the meanings ascribed to them in the Original 13D.


Item 4.              Purpose of Transaction.
                     ----------------------

                     On May 15, 2003, Leucadia sent a letter (the "Letter") to
the Board of Directors of WilTel relating to a potential registered exchange
offer by Leucadia in which stockholders of WilTel would receive 0.3565 common
shares of Leucadia in exchange for each share of WilTel common stock
(representing a 30% premium to WilTel's stock price based on the closing price
of the common stock of Leucadia ($38.65 per share) and WilTel ($10.60 per share)
on May 14, 2003). A copy of the Letter is attached hereto as Exhibit 2 and
incorporated herein by reference.

                     This communication shall not constitute an offer to sell or
the solicitation of an offer to buy any securities, nor shall there be any sale
of securities in any jurisdiction in which such offer, solicitation or sale
would be unlawful prior to registration or qualification under the securities
laws of any such jurisdiction. No offering of securities shall be made except by
means of a prospectus meeting the requirements of Section 10 of the Securities
Act of 1933, as amended.

                     Any offer will only be made through a prospectus, which is
part of a registration statement to be filed with the Securities and Exchange
Commission (the "SEC"). WilTel shareholders are urged to carefully review the
registration statement and the prospectus included therein, and the Schedule TO
and other documents relating to the offer that will be filed by Leucadia with
the SEC when they become available because these documents will contain
important information relating to the offer. You may obtain a free copy of these
documents after they have been filed with the SEC, and other documents filed by
Leucadia with the SEC, at the SEC's Web site at www.sec.gov. Once the
registration statement, as well as any documents incorporated by reference
therein and the Schedule TO have been filed with the SEC, you will also be able
to inspect and copy these documents at the public reference room maintained by
the SEC at 450 Fifth Street, NW, Washington, D.C. 20549. YOU SHOULD CAREFULLY
READ THE PROSPECTUS AND THE TENDER OFFER STATEMENT ON SCHEDULE TO WHEN THEY
BECOME AVAILABLE BEFORE MAKING A DECISION CONCERNING LEUCADIA'S PROPOSED OFFER.
