                       EXCHANGE 0.4242 OF A COMMON SHARE
                                       OF
                         LEUCADIA NATIONAL CORPORATION
                                      AND
                           ONE CONTINGENT SALE RIGHT
                                      FOR
                     EACH OUTSTANDING SHARE OF COMMON STOCK
                                       OF
                       WILTEL COMMUNICATIONS GROUP, INC.

    THIS OFFER, AND YOUR RIGHT TO WITHDRAW SHARES OF WILTEL COMMON STOCK YOU
TENDER INTO THIS OFFER, WILL EXPIRE AT 5:00 PM, NEW YORK CITY TIME, ON
WEDNESDAY, NOVEMBER 5, 2003, UNLESS WE EXTEND THIS OFFER.

    We are offering to exchange 0.4242 of a common share of Leucadia National
Corporation ('Leucadia') and one contingent sale right (a 'CSR') for each
outstanding share of common stock of WilTel Communications Group, Inc.
('WilTel'), on the terms and conditions contained in this prospectus and in the
related letter of transmittal.

    This offer is being made pursuant to an Agreement and Plan of Merger, dated
as of August 21, 2003, by and among Leucadia, Wrangler Acquisition Corp.
('Merger Sub') and WilTel (the 'Merger Agreement'). The board of directors of
WilTel, based upon the recommendation of a special committee comprised of
independent directors, has (i) adopted the Merger Agreement and approved the
transactions contemplated thereby, including this offer, and (ii) recommended
that holders of WilTel common stock accept this offer and tender their WilTel
common stock to Leucadia pursuant to this offer.

    Leucadia currently beneficially owns 47.4% of the outstanding shares of
WilTel common stock. This offer is conditioned on (1) there being validly
tendered and not properly withdrawn prior to the expiration of the offer at
least a majority of the shares of WilTel common stock not beneficially owned by
Leucadia or its affiliates, calculated as described in this prospectus, and (2)
the other conditions described in this prospectus under 'The Offer -- Conditions
of the Offer'.

    After completion of the offer, Leucadia will have WilTel complete a merger
with Merger Sub, in which each outstanding share of WilTel common stock (except
for shares beneficially owned directly or indirectly by Leucadia for its own
account) will be converted into the right to receive Leucadia common shares and
a CSR at the same exchange ratio as used in the offer, subject to dissenters'
rights to the extent applicable under Nevada law. If after the completion of
this offer we beneficially own more than 90% of the outstanding shares of WilTel
common stock, we may effect this merger without the approval of WilTel
stockholders, as permitted under Nevada law.

    Leucadia is not asking WilTel stockholders for a proxy at this time and
WilTel stockholders are requested not to send a proxy. Any solicitation of
proxies will be made pursuant to separate proxy solicitation materials complying
with the requirements of Section 14(a) of the Securities Exchange Act of 1934.

    SEE 'RISK FACTORS' BEGINNING ON PAGE 18 FOR A DISCUSSION OF ISSUES THAT YOU
SHOULD CONSIDER IN DETERMINING WHETHER TO TENDER YOUR SHARES INTO THIS OFFER.

    Leucadia common shares are traded on the New York Stock Exchange and Pacific
Stock Exchange under the symbol 'LUK'. WilTel common stock is traded on NASDAQ
under the symbol 'WTEL'.

                     QUESTIONS AND ANSWERS ABOUT THE OFFER

Q. WHO IS OFFERING TO BUY YOUR SHARES?

A. Our name is Leucadia National Corporation. We are a holding company engaged
   in a variety of businesses, including telecommunications (principally through
   our 47.4% interest in WilTel), banking and lending (principally through
   American Investment Bank, N.A.), manufacturing (through our Plastics
   Division), real estate activities, winery operations, development of a copper
   mine (through our 72.8% interest in MK Gold Company) and property and
   casualty reinsurance. We currently have equity interests of more than 5% in
   the following domestic public companies: AmeriKing, Inc. (6.8%), Carmike
   Cinemas, Inc. (11%), GFSI Holdings, Inc. (6.9%), The FINOVA Group, Inc.
   (indirectly 25% through our interest in Berkadia), HomeFed Corporation
   (30.3%), Jackson Products, Inc. (8.8%), Jordan Industries, Inc. (10.1%),
   ParkerVision, Inc. (7.3%) and WilTel (47.4%).

Q. WHY ARE WE MAKING THE OFFER?

A. We currently own 23,700,000 shares of WilTel common stock, representing 47.4%
   of the outstanding shares of WilTel common stock. We are making the offer for
   the purpose of acquiring all of the outstanding shares of WilTel common stock
   that we do not own.

Q. WHAT WILL YOU RECEIVE IN EXCHANGE FOR THE SHARES OF WILTEL COMMON STOCK THAT
   YOU TENDER INTO THE OFFER?

A. If we complete the offer, you will receive 0.4242 of a Leucadia common share
   and one contingent sale right, or CSR, in exchange for each share of WilTel
   common stock that you validly tender into the offer. We will not issue
   fractional Leucadia common shares. Instead, any WilTel stockholder entitled
   to receive a fractional Leucadia common share will receive a cash payment in
   respect of his fractional interest. See 'The Offer -- Cash Instead of
   Fractional Leucadia Common Shares'. In general, CSRs are uncertificated,
   non-transferable rights that give WilTel stockholders the opportunity to
   receive additional Leucadia common shares if Leucadia completes the sale of
   all or substantially all of WilTel's assets or more than 50% of WilTel's
   capital stock after the closing of the merger and prior to the maturity of
   the CSRs, and the net proceeds to Leucadia from that sale exceed the
   valuation accorded to WilTel's equity in this offer. If Leucadia does not
   consummate such a sale, the CSRs will become worthless, and Leucadia
   currently has no intention to engage in any such sale. See 'Description of
   the CSRs'.

Q. WHAT DOES THE BOARD OF DIRECTORS OF WILTEL THINK OF THE OFFER AND THE MERGER?

A. On August 21, 2003, the board of directors of WilTel, based upon the
   recommendation of a Special Committee comprised of independent directors,
   approved the Merger Agreement, this offer and the merger. The board of
   directors of WilTel also has recommended that WilTel stockholders tender
   their shares of WilTel common stock in this offer. The board of directors of
   WilTel has received a written opinion, dated August 21, 2003, from J.P.
   Morgan Securities Inc. ('JPMorgan'), the financial advisor to the Special
   Committee, to the effect that, as of the date of the opinion and based on and
   subject to the matters described in the opinion, the consideration to be
   received by WilTel stockholders (other than Leucadia and its affiliates) in
   the offer and merger is fair, from a financial point of view, to such
   stockholders. We have been advised that JPMorgan did not assign any monetary
   value to the CSRs in rendering its opinion.

   A summary of JPMorgan's opinion, including the analyses performed, the bases
   and methods of arriving at the opinion, and a description of JPMorgan's
   investigation and assumptions, is provided in WilTel's
   Solicitation/Recommendation Statement on Schedule 14D-9 (the 'WilTel
   Recommendation Statement'). The full text of JPMorgan's written opinion,
   which describes the assumptions made, procedures followed, matters considered
   and limitations on the review undertaken, is attached to the WilTel
   Recommendation Statement. For more information about

                                       i


   the position of the board of directors of WilTel on the offer, see the WilTel
   Recommendation Statement. Please see 'Where You Can Find More Information' to
   learn how to get a copy of the WilTel Recommendation Statement.

Q. WHAT ARE THE POTENTIAL BENEFITS OF THIS OFFER TO WILTEL STOCKHOLDERS?

A. We believe that this offer should be attractive to WilTel stockholders for
   the reasons described elsewhere in this prospectus as well as for the
   following reasons:

     based on the closing prices of Leucadia common shares ($38.65) and shares
     of WilTel common stock ($10.60) on May 14, 2003, the last trading day
     preceding the date of our first announcement of our intention to acquire
     the outstanding shares of WilTel common stock that we do not already own,
     the exchange ratio represented a 54.7% premium over the price of shares of
     WilTel common stock. On September 2, 2003, the last trading date prior to
     the printing of this prospectus for which this information was practicably
     available, the closing prices of a Leucadia common share and a share of
     WilTel common stock, as reported in the consolidated transaction reporting
     system, were $38.21 and $16.11, respectively (based on those share prices,
     the exchange ratio represented a 0.61% premium over the price of shares of
     WilTel common stock). We urge you to obtain current market quotations;

     you will have the opportunity to hold shares in a larger combined company
     which we believe will have greater access to capital to pursue strategic
     growth opportunities than would WilTel on a stand-alone basis;

     you will have the opportunity to continue to share in WilTel's future
     performance through your ownership of Leucadia common shares, as well as an
     opportunity to similarly share in the performance of our other investments
     (which will afford you the benefit of a more diversified investment);

     you will have an opportunity to receive any dividends that may be paid on
     Leucadia common shares that have a record date after you receive those
     shares. In 2002 and 2001, Leucadia paid annual cash dividends of $0.25 per
     common share. The payment of dividends in the future is not guaranteed and
     the payment and timing thereof will be subject to the discretion of our
     board of directors and depend upon general business conditions, legal and
     contractual restrictions on the payment of dividends and other factors that
     our board of directors may deem to be relevant; and

     WilTel and its subsidiaries currently have significant tax loss
     carry-forwards and other attractive tax attributes. Leucadia believes that
     its greater financial resources will provide greater opportunity for future
     investments, unlike WilTel, the cash resources of which are severely
     restricted and which is likely to need to raise capital to meet the debt
     service requirements of its existing debt in 2005. Moreover, Leucadia
     believes that it will be more likely to generate taxable income through its
     diversified interests than will WilTel, the operations of which are
     concentrated in one industry. Consequently, Leucadia believes that
     completion of the offer will increase the likelihood that WilTel's
     significant tax attributes will be utilized for the benefit of
     shareholders.

Q. WHAT ARE SOME OF THE OTHER FACTORS YOU SHOULD CONSIDER IN DECIDING WHETHER TO
   TENDER YOUR SHARES OF WILTEL COMMON STOCK?

A. In addition to the factors described elsewhere in this prospectus, you should
   consider the following:

     as a Leucadia shareholder, your interest in the performance and prospects
     of WilTel would only be indirect and in proportion to your share ownership
     in Leucadia. You, therefore, will not realize the same financial benefits
     of future appreciation in the value of WilTel, if any, that you may realize
     if the offer and the merger were not completed and you remained a WilTel
     stockholder;

     an investment in a company of WilTel's size may be associated with greater
     risk and a greater potential for gain than an investment in a more
     diversified company like Leucadia.

                                       ii


     On the other hand, as a stockholder in a diversified company like Leucadia,
     your investment will be exposed to risks and events that are likely to have
     little or no effect on WilTel; and

     similar to WilTel's articles of incorporation, Leucadia's certificate of
     incorporation contains provisions which generally restrict the ability of a
     person or entity from accumulating 5% or more of the outstanding Leucadia
     common shares and the ability of persons or entities now owning 5% or more
     of the Leucadia common shares from acquiring additional Leucadia common
     shares.

    We describe various factors WilTel stockholders should consider in deciding
whether to tender their shares under 'Risk Factors' and 'Background and Reasons
for the Offer and Subsequent Merger -- Additional Factors for Consideration by
WilTel Stockholders'.

Q: HOW DO YOU PARTICIPATE IN THE OFFER?

A: You are urged to read this entire prospectus carefully, and to consider how
   the offer and the merger affect you. Then, if you wish to tender your shares
   of WilTel common stock, you should complete and sign the enclosed letter of
   transmittal and return it with your stock certificates to the exchange agent
   and depository at its address set forth on the back cover page of this
   prospectus, or, if you hold your shares in 'street name' through a broker,
   ask your broker to tender your shares. Please read this prospectus carefully
   for more information about procedures for tendering your shares, the timing
   of the offer, extensions of the offer period and your rights to withdraw your
   shares from the offer prior to the expiration date.

Q. WHAT ARE THE MOST SIGNIFICANT CONDITIONS TO THE OFFER?

A. The offer is conditioned upon, among other things, satisfaction of the
   condition that there must be validly tendered, and not properly withdrawn,
   prior to the expiration of the offer, at least a majority of the outstanding
   shares of WilTel common stock not owned by Leucadia or its affiliates. In
   connection with the reorganization of WilTel's predecessor company, 1,000,000
   shares of WilTel common stock were issued to a securities holder channeling
   fund for purposes of providing for the settlement of certain claims against
   WilTel's predecessor company. If none of the shares of WilTel common stock
   currently held by such fund are validly tendered in accordance with the terms
   of the offer, then the shares of WilTel common stock in such fund will be
   deemed not outstanding for purposes of this minimum condition. In addition to
   this 'minimum condition', the following conditions must also be met as of the
   expiration of the offer:

     the registration statement, of which this prospectus is a part, shall have
     been declared effective by the SEC;

     all required approvals of the Federal Communications Commission and state
     regulatory authorities for the change of control of WilTel shall have been
     received;

     the absence of any events or changes that, individually or in the
     aggregate, have had or would reasonably be expected to have a material
     adverse effect on WilTel; and

     the absence of legal impediments to the offer or the subsequent merger.

     These conditions and other conditions to the offer are discussed in this
     prospectus under 'The Offer -- Conditions of the Offer'.

Q: IS IT POSSIBLE THAT NO LEUCADIA COMMON SHARES WILL ULTIMATELY BE ISSUED
   PURSUANT TO THE CSRS?

A. Yes. The payment of additional Leucadia common shares in connection with the
   CSRs will be made only if, and to the extent that, (i) Leucadia sells all or
   substantially all of WilTel's assets or more than 50% of WilTel's capital
   stock prior to October 15, 2004, or (ii) Leucadia or WilTel enter into a
   definitive agreement with an unaffiliated third party providing for a sale of
   all or substantially all of the assets of WilTel or more than 50% of WilTel's
   capital stock prior to August 21, 2004 (in which case the CSRs will expire
   upon the later of October 15, 2004 and the completion or abandonment of such
   sale), and in each case, the net proceeds to Leucadia from such sale exceed
   the valuation accorded to WilTel's equity in the offer and merger. For a more
   detailed description of the CSRs, please see 'Description of the CSRs'. If
   Leucadia or

                                      iii


   WilTel do not ultimately consummate such a sale of WilTel's assets or capital
   stock prior to the maturity of the CSRs, the CSRs will become worthless, and
   Leucadia currently has no intention of engaging in any such sale.

Q. IF YOU DECIDE NOT TO TENDER, HOW WILL THIS AFFECT THE OFFER AND YOUR SHARES
   OF WILTEL COMMON STOCK?

A. We will not acquire any shares of WilTel common stock in the offer unless the
   minimum condition is satisfied. As of the date of this prospectus, 26,300,000
   of the outstanding shares of WilTel common stock were not owned by Leucadia
   and its affiliates. Your failure to tender your shares of WilTel common stock
   will reduce the likelihood that we will receive tenders of a sufficient
   number of shares of WilTel common stock to be able to complete the offer.

   The offer is the first step in our acquisition of WilTel and is intended to
   facilitate the acquisition of all outstanding shares of WilTel common stock.
   After completion of the offer we will have WilTel complete a merger with
   Merger Sub. The purpose of the merger would be to acquire all outstanding
   shares of WilTel common stock not exchanged in the offer. In the merger, each
   outstanding share of WilTel common stock (except for shares beneficially
   owned directly or indirectly by Leucadia for its own account) would be
   converted into the right to receive Leucadia common shares and a CSR at the
   same exchange ratio used in the offer, subject to dissenters' rights to the
   extent applicable under Nevada law. If the merger takes place, the only
   difference to you between tendering your WilTel common stock in the offer and
   not tendering your WilTel common stock is that you will receive Leucadia
   common shares and CSRs earlier if you tender your shares in the offer and
   such earlier receipt may entitle you to receive dividends on Leucadia common
   shares if any are declared with a record date after completion of the offer
   and prior to the completion of the merger. An earlier tender of your shares
   of WilTel common stock may, however, help to ensure the satisfaction of the
   minimum condition and the completion of the offer and merger.

Q. HOW LONG WILL IT TAKE TO COMPLETE THE OFFER AND THE SUBSEQUENT MERGER?

A. We hope to complete the offer in the fourth quarter of 2003. The offer is
   currently scheduled to expire on November 5, 2003. However, we may extend the
   offer (i) if the conditions to the offer have not been satisfied as of the
   offer's scheduled expiration or (ii) if we are required to extend the offer
   pursuant to the SEC's tender offer rules. After completion of the offer,
   Leucadia will have WilTel complete a merger with Merger Sub, in which each
   outstanding share of WilTel common stock (except for shares beneficially
   owned directly or indirectly by Leucadia for its own account) will be
   converted into the right to receive Leucadia common shares and a CSR at the
   same exchange ratio as used in the offer, subject to dissenters' rights to
   the extent applicable under Nevada law. If after the completion of the offer
   we beneficially own more than 90% of the outstanding shares of WilTel common
   stock, we may effect this merger without the approval of WilTel stockholders,
   as permitted under Nevada law. If we complete the offer but own less than 90%
   of the WilTel common stock, then the merger will require WilTel stockholder
   approval, and we will complete the merger shortly after a meeting of WilTel
   stockholders to approve the merger, which approval will be assured by our
   vote as the then majority stockholder of WilTel.

Q. DO YOU HAVE TO VOTE TO APPROVE THE OFFER OR THE MERGER?

A. Because we are extending the offer directly to WilTel stockholders, WilTel
   stockholders are not being asked to vote to approve the offer. A vote by
   WilTel stockholders, however, may be required to approve the merger following
   the successful completion of the offer. If we own less than 90% of the
   outstanding shares of WilTel common stock following the completion of the
   offer and you hold shares of WilTel common stock as of the record date for
   voting on the merger, then you may be entitled to vote on the merger. If a
   vote by WilTel stockholders on the merger is required under applicable law,
   WilTel stockholders will receive information materials at that time. Please
   note that because the offer can only be completed if we acquire a majority of
   the outstanding shares of WilTel common stock, once the offer is completed,

                                       iv


   approval of the merger can be accomplished by the vote of Leucadia, as the
   then majority stockholder of WilTel, without the additional votes of any
   other WilTel stockholder. If we own 90% or more of the outstanding common
   stock of WilTel following completion of the offer, the merger can be
   accomplished without any vote under applicable law.

Q. WHAT PERCENTAGE OF THE LEUCADIA COMMON SHARES WILL CURRENT WILTEL
   STOCKHOLDERS OWN AFTER THE COMPLETION OF THE OFFER AND SUBSEQUENT MERGER?

A. We anticipate that the completion of the offer and subsequent merger will
   result in the exchange of the outstanding shares of WilTel common stock that
   we do not currently own into approximately 15.8% of the Leucadia common
   shares outstanding at the conclusion of the transactions, without regard to
   Leucadia stock options or warrants to purchase Leucadia common shares, and
   15.5% on a fully-diluted basis. In general, this assumes that:

     11,156,460 Leucadia common shares would be issued in the offer and the
     subsequent merger;

     59,636,692 Leucadia common shares are outstanding before giving effect to
     the completion of the offer and the subsequent merger;

     no Leucadia common shares are issued pursuant to the CSRs; and

     no WilTel stockholders exercise appraisal (dissenters') rights.

Q. WILL YOU BE TAXED ON THE LEUCADIA COMMON SHARES THAT YOU RECEIVE?

A. Based on the opinion of Weil, Gotshal & Manges LLP, the offer and merger
   should qualify as a reorganization for U.S. federal income tax purposes.
   Assuming reorganization treatment, you would not recognize gain or loss upon
   the receipt of Leucadia common shares in the offer or merger (including the
   receipt of Leucadia common shares under CSRs), other than any gain or loss
   recognized on the receipt of cash instead of fractional shares. In addition,
   if you receive any Leucadia common shares under CSRs, a portion of those
   shares may be treated as interest income to you (depending on certain
   factors). Moreover, certain other tax consequences resulting from your right
   to the receipt of additional Leucadia common shares pursuant to the CSRs are
   unclear. Accordingly, the actual tax consequences to you will depend on your
   particular facts and circumstances, other facts and circumstances surrounding
   the offer and merger (for example, the timing of any payments under the CSRs)
   and the manner in which the Internal Revenue Service, or IRS, applies the law
   in this particular situation. See 'The Offer -- Material U.S. Federal Income
   Tax Consequences'.

Q. HAVE ANY LAWSUITS BEEN FILED IN CONNECTION WITH THE OFFER?

A. Yes. Individual WilTel stockholders have filed complaints in various courts
   purporting to commence class action lawsuits on behalf of WilTel stockholders
   against WilTel, the directors of WilTel and Leucadia. Among other remedies,
   the complaints seek to enjoin the offer and subsequent merger or,
   alternatively, rescission and damages in an unspecified amount. Leucadia
   believes the complaints to be without merit but has entered into an agreement
   in principle to settle the litigations in order to eliminate the burden and
   expense of further litigation, subject to approval from directors and
   officers insurance carriers, based upon increased disclosure in this
   prospectus and the WilTel Recommendation Statement. See 'Certain Legal
   Matters and Regulatory Approvals -- Stockholder Litigation' for a more
   detailed discussion of these lawsuits.

Q. ARE LEUCADIA'S BUSINESS, PROSPECTS AND FINANCIAL CONDITION RELEVANT TO YOUR
   DECISION TO TENDER YOUR SHARES IN THE OFFER?

A. Yes. Shares of WilTel common stock accepted in the offer will be exchanged
   for Leucadia common shares and therefore you should consider Leucadia's
   business, prospects and financial condition before you decide whether to
   tender your shares in the offer. In considering our business, prospects and
   financial condition, you should review the documents incorporated by
   reference in this prospectus because they contain detailed business,
   financial and other information about us. See 'Where You Can Find More
   Information'.

                                    SUMMARY

INTRODUCTION

    We are proposing to acquire all of the outstanding shares of WilTel common
stock that we do not already own. We currently beneficially own 23,700,000
shares of WilTel common stock, representing 47.4% of the outstanding shares of
WilTel common stock.

    We are offering to exchange 0.4242 of a Leucadia common share and one CSR
for each outstanding share of WilTel common stock, upon the terms and subject to
the conditions set forth in this prospectus and the related letter of
transmittal. We will not acquire any shares of WilTel common stock in the offer
unless WilTel stockholders (other than Leucadia and its affiliates) have validly
tendered and not properly withdrawn prior to the expiration of the offer a
majority of the shares of WilTel common stock not owned by Leucadia and its
affiliates, calculated as described in this prospectus. As of the date of this
prospectus, 26,300,000 of the outstanding shares of WilTel common stock were not
owned by Leucadia and its affiliates. There are also other conditions to the
offer that are described under 'The Offer -- Conditions of the Offer'.

    After completion of the offer, Leucadia will have WilTel complete a merger
with Merger Sub, in which each outstanding share of WilTel common stock (except
for shares beneficially owned directly or indirectly by Leucadia for its own
account) will be converted into the right to receive Leucadia common shares and
a CSR at the same exchange ratio as used in the offer, subject to dissenters'
rights to the extent applicable under Nevada law. If after the completion of
this offer we beneficially own more than 90% of the outstanding shares of WilTel
common stock, we may effect this merger without the approval of WilTel
stockholders, as permitted under Nevada law. See 'The Offer -- Approval of the
Merger'.

THE OFFER

    EXCHANGE OF SHARES OF WILTEL COMMON STOCK

    Upon the terms and subject to the conditions of the offer, promptly after
the expiration of the offer we will exchange shares of WilTel common stock which
are validly tendered and not properly withdrawn for Leucadia common shares and
CSRs. We are offering to exchange 0.4242 of a Leucadia common share and one CSR
for each outstanding share of WilTel common stock.

    The CSRs will be uncertificated rights and will be non-assignable and
non-transferable by any holder thereof, except as required by any applicable
community property laws or laws of descent and distribution. CSRs will not be
represented by any certificate. A CSR will not entitle its holder to any of the
rights of a shareholder in Leucadia (including voting or dividend rights).

    In general, the CSRs give WilTel stockholders the opportunity to receive
additional Leucadia common shares if Leucadia sells all or substantially all of
WilTel's assets or more than 50% of WilTel's capital stock prior to the
expiration of the CSRs (which Leucadia has no plans to do) and the net proceeds
to Leucadia from such sale exceed the valuation accorded to WilTel's equity in
the offer and merger. If Leucadia does not consummate such a sale prior to the
maturity of the CSRs, the CSRs will become worthless, and Leucadia currently has
no intention to engage in any such sale. The CSRs will expire and be of no
further force and effect on October 15, 2004, unless Leucadia or WilTel enter
into a definitive agreement with an unaffiliated third party providing for a
sale of all or substantially all of the assets of WilTel or more than 50% of
WilTel's capital stock after the completion of the merger and prior to August
21, 2004, in which case the CSRs will expire upon the later of October 15, 2004
and the completion or abandonment of such sale. The maximum number of Leucadia
common shares issuable pursuant to the CSRs is 11,000,000, regardless of the
amount of net proceeds received by Leucadia from any subsequent sale of WilTel.
For a more detailed description of the CSRs, please see 'Description of the
CSRs'.

    TIMING OF THE OFFER

    We commenced the offer on September 4, 2003. The offer is scheduled to
expire at 5:00 PM, New York City time, on November 5, 2003, unless we extend the
period of the offer. All references to the expiration of the offer mean the time
of expiration, as extended. For more information, see the discussion under
' -- Extension, Termination and Amendment' below.

    EXTENSION, TERMINATION AND AMENDMENT

    If any condition to the offer is not satisfied or, if permissible, waived,
by any scheduled expiration date of the offer, then we may extend the expiration
date from time to time. Each extension may last for no more than ten business
days, unless WilTel and Leucadia agree in writing to allow for a longer period.
We also have the right to extend the offer for any period of time required by
the applicable rules and regulations of the SEC. Leucadia or WilTel can
terminate the Merger Agreement if the offer is not consummated by January 15,
2004. We can extend the offer by giving oral or written notice of an extension
to American Stock Transfer & Trust Company, the exchange agent and depository
for the offer. If we decide to extend the offer, we will make a public
announcement to that effect no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration. We are not giving
any assurance that we will extend the offer. During any extension, all shares of
WilTel common stock previously tendered and not withdrawn will remain deposited
with the exchange agent and

                                       2


depository, subject to your right to withdraw your shares of WilTel common stock
as described under 'The Offer -- Withdrawal Rights'.

    Subject to the SEC's applicable rules and regulations and subject to the
limitations contained in the Merger Agreement, we also reserve the right, in our
discretion:

     to terminate the offer and not accept for exchange or exchange any shares
     of WilTel common stock not previously accepted for purchase, or purchased,
     upon the failure of any of the conditions of the offer to be satisfied
     prior to the expiration of the offer; and

     to waive any condition or otherwise amend the offer in any respect prior to
     the expiration of the offer, by giving oral or written notice of such
     delay, termination or amendment to the exchange agent and depository and by
     making a public announcement.

    We will follow any extension, termination or amendment, as promptly as
practicable, with a public announcement. Subject to the requirements of the
Securities Exchange Act of 1934, as amended (the 'Exchange Act'), and other
applicable law, and without limiting the manner in which we may choose to make
any public announcement, we assume no obligation to publish, advertise or
otherwise communicate any public announcement other than by making a release to
the Dow Jones News Service.

    PROCEDURE FOR TENDERING SHARES

    For you to validly tender shares of WilTel common stock into the offer, you
must do one of the following:

     Deliver certificates of your shares, a properly completed and duly executed
     letter of transmittal or a copy thereof that has been manually signed,
     along with any other required documents, to the exchange agent and
     depository at one of its addresses set forth on the back cover of this
     prospectus prior to the expiration of the offer;

     Arrange for a book-entry transfer of your shares to be made to the exchange
     agent and depository's account at The Depository Trust Company, or DTC, and
     receipt by the exchange agent and depository of a confirmation of this
     transfer prior to the expiration of the offer, and the delivery of a
     properly completed and duly executed letter of transmittal or a copy
     thereof that has been manually signed, and any other required documents, to
     the exchange agent and depository at one of its addresses set forth on the
     back cover of this prospectus prior to the expiration of the offer; or

     Arrange for a book-entry transfer of your shares to the exchange agent and
     depository's account at DTC and receipt by the exchange agent and
     depository of confirmation of this transfer, including an 'agent's
     message,' prior to the expiration of the offer.

    These deliveries and arrangements must be made before the expiration of the
offer. TENDERS BY NOTICE OF GUARANTEED DELIVERY WILL NOT BE ACCEPTED. See 'The
Offer -- Procedure for Tendering Shares'.

    WITHDRAWAL RIGHTS

    You may withdraw any shares of WilTel common stock that you previously
tendered into the offer at any time before the expiration of the offer by
following the procedures described under 'The Offer -- Withdrawal Rights'. In
addition, if we have not accepted tendered shares for exchange by November 3,
2003, you may withdraw tendered shares at any time thereafter.

    DELIVERY OF LEUCADIA COMMON SHARES

    Upon the terms of the offer and subject to the satisfaction (or, where
permissible, waiver) of the conditions to the offer as of the expiration of the
offer, we will, promptly after expiration of the offer, exchange shares of
WilTel common stock validly tendered and not properly withdrawn

                                       3


for Leucadia common shares, CSRs and cash instead of fractional shares. The CSRs
will not be evidenced by any form of certificate. In all cases, exchange of
shares of WilTel common stock tendered and accepted for exchange pursuant to the
offer will be made only if the exchange agent and depository timely receives
(1) certificates for those shares of WilTel common stock, or a timely
confirmation of a book-entry transfer of those shares of WilTel common stock in
the exchange agent and depository's account at DTC, and a properly completed and
duly executed letter of transmittal, or a manually signed copy, and any other
required documents, or (2) a timely confirmation of a book-entry transfer of
those shares of WilTel common stock in the exchange agent and depository's
account at DTC, together with an 'agent's message' as described above under
' -- Procedure for Tendering Shares'.

    CASH INSTEAD OF FRACTIONAL LEUCADIA COMMON SHARES

    We will not issue any fraction of a Leucadia common share pursuant to the
offer or the merger. Instead, each tendering stockholder who would otherwise be
entitled to a fraction of a Leucadia common share, after the combining of all
fractional shares to which tendering stockholders would otherwise be entitled,
will receive cash in respect of his fractional interests. See 'The Offer -- Cash
Instead of Fractional Leucadia Common Shares'.

    MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

    Based on the opinion of Weil, Gotshal & Manges LLP, the offer and merger
should qualify as a reorganization for U.S. federal income tax purposes.
Assuming reorganization treatment, you would not recognize gain or loss upon the
receipt of Leucadia common shares in the offer or merger (including the receipt
of Leucadia common shares under CSRs), other than any gain or loss recognized on
the receipt of cash instead of fractional shares. In addition, if you receive
any Leucadia common shares under CSRs, a portion of those shares may be treated
as interest income to you (depending on certain factors). Moreover, certain
other tax consequences resulting from your right to the receipt of additional
Leucadia common shares pursuant to the CSRs are unclear. Accordingly, the actual
tax consequences to you will depend on your particular facts and circumstances,
other facts and circumstances surrounding the offer and merger (for example, the
timing of any payments under the CSRs) and the manner in which the IRS applies
the law in this particular situation. See 'The Offer -- Material U.S. Federal
Income Tax Consequences'.

    REGULATORY APPROVALS

    We are not aware of any regulatory license or permit material to the
business of WilTel and its subsidiaries, on a consolidated basis, that may be
materially adversely affected by our acquisition of WilTel common stock, or any
regulatory filing or approval that would be required for our acquisition of
WilTel common stock, other than all required approvals of the Federal
Communications Commission and state regulatory authorities for the change of
control of WilTel and the expiration or termination of the waiting period under
the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended. We intend
to make all required filings to seek such approvals, as well as all required
filings under the Securities Act of 1933, as amended (the 'Securities Act'), and
the Exchange Act, in connection with the offer and merger. We are unaware of any
requirement for the filing of information with, or the obtaining of the approval
of, governmental authorities in any non-U.S. jurisdiction that is applicable to
the offer or the merger.

    APPRAISAL (DISSENTERS') RIGHTS

    Under Nevada law, you will not have any appraisal (dissenters') rights in
connection with the offer. However, appraisal (dissenters') rights may be
available in connection with a 'short form' merger. For a discussion of these
appraisal (dissenters') rights, see 'The Offer -- Appraisal (Dissenters')
Rights'.

                                       4


    ACCOUNTING TREATMENT

    Our acquisition of WilTel common stock pursuant to the offer and the merger
will be accounted for under the purchase method of accounting in accordance with
generally accepted accounting principles in the United States. In addition, as a
result of acquiring the additional shares of WilTel common stock, we will
consolidate the financial position and results of operations of WilTel from the
date of this additional acquisition and no longer account for our investment in
WilTel under the equity method of accounting.

    COMPARISON OF RIGHTS OF WILTEL STOCKHOLDERS AND LEUCADIA SHAREHOLDERS

    WilTel is a Nevada corporation and Leucadia is a New York corporation. If we
complete the offer, holders of WilTel common stock will become Leucadia
shareholders, and their rights as stockholders will be governed by Leucadia's
certificate of incorporation and by-laws, and New York law. There are
differences between the articles of incorporation and by-laws of WilTel and the
certificate of incorporation and by-laws of Leucadia, and between Nevada law and
New York law. For a summary of material differences between the rights of
holders of WilTel common stock and holders of Leucadia common shares, see
'Comparison of Rights of Holders of WilTel Common Stock and Holders of Leucadia
Common Shares'.

           SELECTED HISTORICAL FINANCIAL DATA OF LEUCADIA AND WILTEL

        We are providing the following selected financial information to
    assist you in analyzing the financial aspects of the offer and the
    subsequent merger. We derived the financial information presented for
    Leucadia and for WilTel as of, and for the six-month period ended,
    June 30, 2003 and 2002 from the unaudited financial statements contained
    in Leucadia's and WilTel's respective Quarterly Reports on Form 10-Q for
    the quarterly period ended June 30, 2003. We derived the financial
    information presented for Leucadia and for WilTel as of, and for each of
    the five years for the period ended, December 31, 2002 from the audited
    financial statements and other financial information contained in
    Leucadia's and WilTel's respective Annual Reports on Form 10-K for those
    years. WilTel is the successor to Williams Communications Group, Inc.
    You should read the respective selected historical financial information
    of Leucadia and WilTel presented below in conjunction with the
    historical consolidated financial statements and related notes and
    management's discussion and analysis contained in the annual, quarterly
    and other reports filed by Leucadia and WilTel with the SEC, which we
    have incorporated by reference into this prospectus. See 'Where You Can
    Find More Information'. The selected historical financial information
    presented below for the six months ended June 30, 2003 and 2002 have
    been derived from unaudited financial statements; however, in the
    opinion of Leucadia's and WilTel's management, such financial
    information for their respective companies contains all adjustments,
    consisting only of normal recurring items, necessary to present fairly
    the financial information for such periods. The results of operations
    for the six months ended June 30, 2003 may not be indicative of annual
    results of operations.

    (1)    Includes net securities gains (losses) of $214,000 and
           $(12,298,000) for the six month periods ended June 30, 2003 and
           2002, respectively, and $(37,066,000), $28,450,000, $124,964,000,
           $16,268,000 and $(66,159,000) for the years ended December 31,
           2002, 2001, 2000, 1999 and 1998, respectively.

    (2)    During 2002, the Internal Revenue Service completed the audit of
           Leucadia's consolidated federal income tax returns for the years
           1996 through 1999, without any material tax payment required from
           Leucadia. As a result of this favorable resolution of various
           federal income tax contingencies, the income tax provision for
           2002 reflects a benefit of approximately $120,000,000.

    (3)    For the six month period ended June 30, 2003 and for the period from
           the acquisition of WilTel through December 31, 2002, Leucadia
           recorded $57,100,000 and $13,400,000, respectively, of pre-tax
           losses from this investment under the equity method of accounting.
           The book value of Leucadia's investment in WilTel was $284,100,000
           at June 30, 2003 and was $340,600,000 at December 31, 2002.

           the segment segregated and reported as discontinued operations
           for prior periods.

                      UNAUDITED COMPARATIVE PER SHARE DATA

    In the following table we present unaudited historical per share data for
Leucadia and WilTel, respectively, combined unaudited pro forma per share data
for Leucadia and historical and equivalent unaudited pro forma per share data
for WilTel, as of and for the six months ended June 30, 2003 and as of and for
the year ended December 31, 2002. We present the unaudited pro forma per share
data for comparative purposes only. The data does not purport to be indicative
of (1) the results of operations or financial position which would have been
achieved if the offer and the subsequent merger had been completed at the
beginning of the period or as of the date indicated, or (2) the results of
operations or financial position which may be achieved in the future. The pro
forma per share data does not reflect any payment that may be required to be
made in connection with the exercise of appraisal (dissenters') rights by WilTel

 (a) The WilTel equivalent pro forma per share data is computed by multiplying
     the Leucadia combined pro forma per share data by the exchange ratio of
     0.4242 of a Leucadia common share to be issued for each share of WilTel
     common stock.

 (b) For the determination of the Leucadia combined pro forma income (loss) from
     continuing operations per share data, see the Notes to Unaudited Pro Forma
     Consolidated Financial Information contained elsewhere in this prospectus.

 (c) The historical book values per common share were computed by dividing
     shareholders' equity by the number of shares of common stock outstanding at
     the end of the period. The Leucadia combined pro forma book value per share
     of common stock is computed by dividing pro forma shareholders' equity by
     the pro forma number of shares of common stock outstanding as of June 30,
     2003.

 (d) The Leucadia combined pro forma cash dividends per share of common stock
     assumes that the historical amount paid per share of common stock would
     have been paid on each of the pro forma number of shares of common stock.

                       COMPARATIVE PER SHARE MARKET DATA

    In the following table we present:

     the prices of a Leucadia common share and a share of WilTel common stock as
     of the close of trading on August 11, 2003, the last trading date prior to
     the date that Leucadia and WilTel announced an agreement in principle on
     the offer and merger, as reported in the consolidated transaction reporting
     system, and

     the equivalent price of a share of WilTel common stock, based on the
     exchange ratio.



                                                               LEUCADIA      WILTEL        WILTEL

Closing price per share as of August 11, 2003...............    $37.56       $14.06        $15.93


---------
(1) We calculated the WilTel equivalent price by multiplying the applicable
    Leucadia closing price by the exchange ratio in the offer and the subsequent
    merger of 0.4242 of a Leucadia common share for each share of WilTel common
    stock.

                              -------------------

    On September 2, 2003, the last trading date prior to the printing of this
prospectus for which this information was practicably available, the closing
prices of a Leucadia common share and a share of WilTel common stock, as
reported in the consolidated transaction reporting system, were $38.21 and
$16.11, respectively.

    The market prices of Leucadia common shares and shares of WilTel common
stock are subject to fluctuation. The actual value of the Leucadia common shares
you receive in the offer and the merger will likely differ from the values
illustrated. You are urged to obtain current market quotations. See 'Comparative
Per Share Market Price and Dividend Information'.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

    The following unaudited pro forma consolidated financial statements have
been prepared under the assumption that all of the outstanding shares of WilTel
common stock not owned by Leucadia are acquired pursuant to the offer and
merger. The offer is subject to a minimum condition that at least half of the
shares not owned by Leucadia or its affiliates are validly tendered. If this
condition is not satisfied, then Leucadia will not acquire any shares. If it is
satisfied, then Leucadia is certain to own a sufficient number of shares (at
least 73.7%) to assure, through its vote as the then majority stockholder of
WilTel, that the merger will be consummated and that Leucadia will own all of
the shares. Accordingly, the pro forma financial information assumes all of the
shares are acquired.

    If after completion of the offer we own at least 90% of the outstanding
shares of WilTel common stock, we may complete the acquisition of the shares of
WilTel common stock that we do not own through a 'short-form merger' without a
vote of WilTel stockholders. If we effect a short-form merger, it can generally
be completed within a few days following completion of the offer. If we do not
own at least 90% of the outstanding shares of WilTel common stock after
completion of the offer, we may complete the acquisition of the shares of WilTel
common stock that we do not own by a 'long-form merger' through a vote of WilTel
stockholders. A long-form merger will require the calling of a stockholder
meeting and the preparation of an information or proxy statement in respect of
the merger. We estimate that it may take as long as several months

                                       10


from the completion of the offer for us to complete a long-form merger. See 'The
Offer -- Approval of The Merger'.

    The execution of the Merger Agreement on August 21, 2003 created a
measurement date for accounting purposes enabling Leucadia to determine the
value of the Leucadia common shares to be issued. Leucadia averaged the closing
prices of its common shares for the five-business day period commencing two days
before and ending two days after the Merger Agreement was executed. That
average, $37.90 per share, was used to calculate the aggregate value of the
shares issued for purposes of the unaudited pro forma consolidated financial
statements that follow, and will also be used to determine the actual cost of
the acquisition if the offer and merger are consummated pursuant to the terms of
the Merger Agreement.

         NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

    The unaudited pro forma consolidated balance sheet as of June 30, 2003
assumes that all of the shares of WilTel common stock not owned by Leucadia are
acquired and reflects the adjustments necessary to record the acquisition as
though it had occurred on June 30, 2003. The aggregate purchase price of
$423,800,000 for the shares of WilTel common stock not already owned by Leucadia
consists of $422,800,000 of Leucadia common shares and estimated cash expenses
of $1,000,000, as described in the notes below.

    The unaudited pro forma consolidated statement of operations for the year
ended December 31, 2002 and the unaudited pro forma consolidated statement of
operations for the six months ended June 30, 2003 have been prepared assuming
the acquisition of WilTel common stock occurred on January 1, 2002 and reflect
the effects of certain adjustments to the historical consolidated financial
statements that result from the acquisition of WilTel common stock. WilTel
emerged from bankruptcy in October 2002 and adopted the provisions of fresh
start accounting on October 31, 2002. WilTel's emergence from bankruptcy
resulted in a new reporting entity for accounting purposes and, as such, its
financial results for periods before and after its emergence are presented
separately.

    At acquisition, under generally accepted accounting principles, Leucadia is
required to allocate the purchase price to specific tangible and intangible
assets and liabilities based upon their relative fair values. Leucadia will
employ independent appraisals and other techniques to determine these fair
values. For purposes of the pro forma balance sheet, Leucadia principally
utilized the independent appraisals, market quotes, discounted cash flow
techniques and comparable sales information utilized by WilTel to prepare their
fresh start balance sheet upon emergence from bankruptcy as of October 31, 2002.
Leucadia reviewed this information in light of the passage of time since its
preparation and the changes in the telecommunications industry to determine
whether the information was still in a range of reasonable estimates of fair
values for use in the pro forma balance sheet, and concluded that it was. At
acquisition, the determination of the actual relative fair values may result in
a different allocation than was assumed for the pro forma financial statements.
Any such differences are expected to result in an increase or decrease to
property, plant and equipment and deferred income, could also result in a
different weighted average life used for depreciation and amortization purposes
and, as a result, could either increase or decrease the annual amount of actual
depreciation and amortization recorded. Accordingly, except for the effects of
the pro forma adjustments to property, plant and equipment, the June 30, 2003
historical WilTel balances were assumed to be reasonable estimates of fair
values for purposes of the allocation of the purchase price in the pro forma
balance sheet.

    The 'Pro Forma Adjustments' column combines the accounting effects of
Leucadia's actual purchases in 2002 with the pro forma accounting effect of the
offer to purchase the remaining shares. The principal accounting differences
between the actual 2002 purchases and the pro forma 2003 purchase are the amount
of excess purchase price over WilTel's historical book value of assets acquired
for each transaction, and the related depreciation and amortization expenses
reflected, on a pro forma basis, for each transaction. As of June 30, 2003, the
amount of the excess was $13,689,000 for the 2002 purchases and $80,813,000, on
a pro forma basis, for the 2003 offer to acquire the remaining shares. Each of
these amounts is assumed to be amortized as depreciation and amortization
expense over an average life of 15 years. In addition, the 2003 offer to
purchase the remaining shares will allow Leucadia to recognize WilTel's deferred
tax assets in an amount equal to Leucadia's deferred tax liability.

    The following notes pertain to the unaudited pro forma consolidated
financial statements:

     (a) Represents estimated expenses incurred in connection with the
         acquisition of WilTel common stock in the offer.

     (b) Represents the preliminary adjustment to fair value of the assets
         acquired. The excess of the amount paid to acquire WilTel common stock
         in the offer over the historical carrying amounts of net assets
         acquired is assumed allocated to property, plant and equipment.

                                       15


     (c) Represents the elimination of the carrying amount of Leucadia's 47.4%
         interest in WilTel prior to the acquisition.

     (d) Represents the recognition of net deferred tax assets of WilTel in an
         amount equal to Leucadia's deferred tax liabilities. Additional
         deferred tax assets have not been recognized as they are not deemed
         more likely than not to be realizable.

     (e) Represents the elimination of the historical stockholders' equity of
         WilTel.

     (f) Reflects the issuance of 11,156,460 Leucadia common shares, based on a
         valuation of $37.90 per share, the average of the closing share prices
         for the five business day period commencing two days before and ending
         two days after the Merger Agreement was executed.

     (g) Represents an adjustment to the historical amortization of WilTel's
         deferred revenue as a result of the adjustment to the carrying amount
         of deferred revenue to reflect its fair value as of the date of
         acquisition.

     (h) The adjustment to reduce telecommunications cost of sales by $6,614,000
         results from the recognition of a liability for the fair value of
         unfavorable contracts as of the date of the acquisition assumed in the
         pro forma financial statements. Cost of sales has been reduced for
         actual amounts expensed for these contracts during the ten month period
         ended October 31, 2002; no other amounts were expensed for these
         contracts for any other period presented. The adjustment to reduce
         asset impairments and restructuring charges by $8,572,000 substantially
         reflects the reversal of severance expense recorded by WilTel, which
         was recognized by Leucadia as a liability in its allocation of the
         purchase price to the fair value of the acquired liabilities.

     (i) For both periods presented, represents an increase to depreciation
         expense ($3,150,000 for 2003 and $6,300,000 for 2002) related to the
         adjustment to fair value of property, plant and equipment at June 30,
         2003, which fair value adjustment is assumed amortized over an average
         life of 15 years. Property, plant and equipment primarily consists of
         network equipment (fiber, optronics and capacity IRUs) with depreciable
         lives of 3-20 years, rights-of-way with depreciable lives of 20 years,
         buildings and leasehold improvements with depreciable lives of 10-30
         years, computer equipment and software with depreciable lives of 2-3
         years, general office furniture and fixtures of 5-8 years, and
         construction in progress. Depreciation expense is computed using the
         straight-line method.

         The 2002 period also includes a reduction of $238,153,000 to WilTel's
         historical depreciation expense, as the historical carrying amount of
         WilTel's property, plant and equipment as of January 1, 2002 is nearly
         $3 billion more than the preliminary amount allocated to property,
         plant and equipment assumed in the pro forma financial statements.
         Accordingly, depreciation expense was substantially reduced on a pro
         forma basis since the actual depreciation expense recorded on a much
         larger asset would not have been recorded on a pro forma basis.

     (j) Represents the reversal of the gain recognized upon the discharge of
         WilTel's indebtedness in bankruptcy ($4.3 billion) and the reversal of
         the net charge recognized upon WilTel's application of fresh start
         accounting adjustments to the historical carrying amounts of its asset
         and liabilities ($2.1 billion).

     (k) Represents the reversal of historical interest expense related to all
         debt that was converted to equity under WilTel's bankruptcy plan.

     (l) Represents the reversal of Leucadia's historical federal income tax
         provision as losses generated by WilTel exceed Leucadia's historical
         income. Leucadia did not record in its historical financial statements
         a deferred tax benefit for its share of WilTel's losses, as its ability
         to utilize these unrealized capital losses to reduce taxes due on
         capital gains in the future was uncertain. Therefore, no amount of
         adjustment (l) relates to Leucadia's share of WilTel's losses. The 'Pro
         Forma As Adjusted' amounts for the line item 'income tax (benefit)
         provision' for all periods includes amounts for state income and
         franchise taxes

                                       16


         and, for the 2002 period, a reversal of Leucadia tax reserves as a
         result of the resolution of certain federal income tax contingencies
         unrelated to the WilTel acquisition.

     (m) Represents the reversal of Leucadia's recognition of its share of
         WilTel's losses under the equity method of accounting as a result of
         the pro forma consolidation.

     (n) For basic and diluted earnings (loss) per common share, represents the
         number of shares issued in connection with the acquisition of WilTel
         common stock pursuant to the offer. In addition, for the year ended
         December 31, 2002, the pro forma adjustment for diluted earnings (loss)
         per common share includes a reduction of approximately 349,000 shares
         issuable pursuant to outstanding Leucadia options, that are included in
         the historical calculation but not in the pro forma calculation as the
         result is antidilutive.

                                  RISK FACTORS

    In deciding whether to tender your shares pursuant to the offer, you should
read this prospectus (including the discussion under 'Background and Reasons for
the Offer and Subsequent Merger -- Additional Factors for Consideration by
WilTel Stockholders -- Other Factors You Should Consider' and 'Certain Effects
of the Offer') and the documents which we incorporate by reference into this
prospectus carefully. You should also carefully consider the following factors:

RISKS RELATED TO THE OFFER AND THE SUBSEQUENT MERGER

    THE NUMBER OF LEUCADIA COMMON SHARES THAT YOU WILL RECEIVE IN THE OFFER
AND/OR THE SUBSEQUENT MERGER WILL BE BASED UPON A FIXED EXCHANGE RATIO. THE
VALUE OF THE LEUCADIA COMMON SHARES AT THE TIME YOU RECEIVE THEM COULD BE LESS
THAN AT THE TIME YOU TENDER YOUR SHARES OF WILTEL COMMON STOCK.

    In the offer and the subsequent merger, each share of WilTel common stock
will be exchanged for 0.4242 of a Leucadia common share and one CSR. This is a
fixed exchange ratio. We will not adjust the exchange ratio as a result of any
change in the market price of Leucadia common shares or WilTel common stock
between the date of this prospectus and the date you receive Leucadia common
shares. The market price of the Leucadia common shares may be lower on the date
you receive such shares than it is today or on the date you tender shares of
WilTel common stock or on the date the offer expires or the date a subsequent
merger is completed, because of changes in the business, operations or prospects
of Leucadia, market reactions to our offer, general market and economic
conditions, and other factors. You are urged to obtain current market quotations
for Leucadia common shares and WilTel common stock. See 'Comparative Per Share
Market Price and Dividend Information'.

    THE TRADING PRICE OF LEUCADIA COMMON SHARES MAY BE AFFECTED BY FACTORS IN
ADDITION TO THOSE FACTORS AFFECTING THE PRICE OF WILTEL COMMON STOCK. THE PRICE
OF LEUCADIA COMMON SHARES COULD DECLINE FOLLOWING THE OFFER.

    If we complete the offer, holders of WilTel common stock will become holders
of Leucadia common shares. Although we currently own 47.4% of the outstanding
shares of WilTel common stock, we also own and operate other businesses and have
significant interests in other companies. Accordingly, our results of operations
and business, as well as the trading price of Leucadia common shares, will be
affected by factors in addition to those affecting WilTel's results of
operations and business and the price of WilTel common stock. The price of
Leucadia common shares may decrease after we accept shares of WilTel common
stock for exchange in the offer and complete the subsequent merger. For a
discussion of some of the factors that could affect our results of operations or
business, or the trading price of our common shares, see pages 24-25 of our 2002
Annual Report on Form 10-K and pages 16-17 of our Quarterly Report on Form 10-Q
for the quarterly period ended June 30, 2003.

    DIRECTORS OF WILTEL HAVE POTENTIAL CONFLICTS OF INTERESTS WITH RESPECT TO
THE OFFER.

    You should be aware that potential conflicts of interest exist with respect
to the offer and subsequent merger among members of WilTel's board of directors
in that two of the nine members of the WilTel board of directors (Ian M. Cumming
and Joseph S. Steinberg) are the Chairman and President, respectively, directors
and principal shareholders of Leucadia. In addition, Leucadia has designated two
other members (Messrs. Alan J. Hirschfield and Jeffrey C. Keil) to the WilTel
board of directors. For additional information on the interests that WilTel's
board members may have in the offer and subsequent merger, see 'Interests of
Certain Persons in the Offer and Subsequent Merger'.

    THE OFFER AND MERGER MAY NOT QUALIFY AS A TAX-FREE REORGANIZATION FOR UNITED
STATES FEDERAL INCOME TAX PURPOSES.

    Although WilTel has received an opinion from Weil, Gotshal & Manges LLP that
the offer and merger should qualify as a reorganization for U.S. federal income
tax purposes, you should be

                                       18


aware that the tax consequences are not entirely free from doubt and the opinion
is not binding on the IRS. In the event that the IRS successfully challenges the
tax-free characterization of the offer and merger, you would be taxed on any
gain recognized as a result of the offer and merger. Please consult your tax
advisor for a full understanding of the tax consequences to you and see 'The
Offer -- Material U.S. Federal Income Tax Consequences'.

RISKS RELATED TO LEUCADIA AND LEUCADIA COMMON SHARES

    LEUCADIA IS DEPENDENT ON CERTAIN KEY PERSONNEL. THESE INDIVIDUALS ARE ALSO
SIGNIFICANT SHAREHOLDERS OF LEUCADIA AND HAVE SIGNIFICANT INFLUENCE OVER
LEUCADIA'S AFFAIRS.

    Leucadia is dependent on the services of its senior management, including
Ian M. Cumming and Joseph S. Steinberg, Leucadia's Chairman of the Board and
President, respectively. Messrs. Cumming's and Steinberg's employment agreements
with Leucadia expire June 30, 2005. As of June 30, 2003, Messrs. Cumming and
Steinberg and their respective families (excluding certain private charitable
foundations) beneficially owned approximately 15.7% and 15.4% of the outstanding
Leucadia common shares, respectively. Accordingly, Messrs. Cumming and Steinberg
could exert significant influence over all matters requiring approval by
Leucadia shareholders, including the election or removal of directors and the
approval of mergers or other business combination transactions. Certain of
Leucadia's public debt instruments ($339,464,000 outstanding at June 30, 2003)
contain provisions granting the holders thereof the right, subject to certain
exceptions, to require Leucadia to repurchase such debt at 101% of principal
amount plus accrued but unpaid interest upon a change of control (as defined in
such instruments) of Leucadia. None of these change of control provisions would
be triggered by consummation of the offer or subsequent merger addressed in this
prospectus.

    LEUCADIA COMMON SHARES ARE SUBJECT TO TRANSFER RESTRICTIONS.

    Leucadia and certain of its subsidiaries have or have had tax loss
carryforwards and other tax attributes, the amount and availability of which are
subject to certain qualifications, limitations and uncertainties. In order to
reduce the possibility that certain changes in ownership could impose
limitations on the use of the tax loss carryforwards, Leucadia's certificate of
incorporation contains provisions which generally restrict the ability of a
person or entity from accumulating 5% or more of the Leucadia common shares and
the ability of persons or entities now owning 5% or more of the Leucadia common
shares from acquiring additional Leucadia common shares. The restrictions will
remain in effect until the earliest of (a) December 31, 2005, (b) the repeal of
Section 382 of the Internal Revenue Code (or any comparable successor provision)
and (c) the beginning of a taxable year of Leucadia to which certain tax
benefits may no longer be carried forward. Such restrictions may be waived by
Leucadia's board of directors. Leucadia shareholders are advised to carefully
monitor their ownership of Leucadia common shares and consult their own legal
advisors and/or Leucadia to determine whether their ownership of Leucadia common
shares approaches the proscribed level. All certificates representing the
Leucadia common shares offered by this prospectus will bear a legend indicating
that such shares are subject to such transfer restrictions.

    If we continue to have loss carryforwards and attributes whether or not the
offer is consummated, we may seek to amend our certificate of incorporation to
extend the December 31, 2005 expiration date for the restrictions on the
accumulation on our common shares described in the preceding paragraph. Assuming
we complete the offer but our certificate of incorporation is not amended to
extend the December 31, 2005 expiration date, transfers of our stock can have a
significant impact on the utilization of Leucadia's existing tax losses and
other tax attributes, including those of WilTel.

    LEUCADIA MAY REDUCE OR CEASE TO PAY DIVIDENDS ON ITS COMMON SHARES.

    In 2002 and 2001, Leucadia paid annual cash dividends of $0.25 per common
share. However, we can provide no assurance that Leucadia will pay dividends on
its common shares in the future (or, if Leucadia does pay dividends, as to the
amount thereof). The payment of dividends on Leucadia common shares in the
future is subject to the discretion of Leucadia's board of directors

                                       19


and will depend upon general business conditions, legal and contractual
restrictions on the payment of dividends and other factors that our board of
directors may deem to be relevant. In connection with the declaration of
dividends or the making of distributions on, or the purchase, redemption or
other acquisition of Leucadia common shares, Leucadia is required to comply with
certain restrictions contained in certain of its debt instruments. In addition,
Leucadia's regulated subsidiaries are restricted in the amount of distributions
that can be made to Leucadia without regulatory approval. Leucadia may consider
the recent changes in U.S. tax laws lowering the tax rate on dividends in
determining its dividend policy.

                                       20

           BACKGROUND AND REASONS FOR THE OFFER AND SUBSEQUENT MERGER

    The following discussion presents background information concerning the
offer and subsequent merger and describes our reasons for undertaking the
proposed transaction. Please see ' -- Additional Factors for Consideration by
WilTel Stockholders' for further information relating to the proposed
transactions.

LEUCADIA'S INITIAL INVESTMENTS IN WILTEL

    On October 15, 2002 (the 'Effective Date'), WilTel emerged as the successor
to Williams Communications Group, Inc. ('WCG') pursuant to a plan of
reorganization approved by the bankruptcy court (the 'Plan'). The Plan was
proposed by WCG, the Official Committee of Unsecured Creditors of WCG, and
Leucadia.

    Leucadia acquired an aggregate of 22,000,000 shares (44%) of WilTel common
stock on the Effective Date pursuant to two transactions provided for under the
Plan. First, pursuant to an agreement with The Williams Companies Inc. ('TWC'),
Leucadia acquired from TWC, for a purchase price of $180,000,000, certain claims
that TWC had against WCG. In accordance with the Plan, WilTel issued 11,775,000
shares of its common stock to Leucadia in satisfaction of such claims. Second,
on the Effective Date Leucadia invested $150,000,000 in WilTel in exchange for
10,225,000 shares of WilTel common stock. On October 28, 2002, Leucadia
purchased an additional 1,700,000 shares of WilTel common stock for an aggregate
purchase price of $20,400,000 in a private transaction. As a result of those
acquisitions, Leucadia is currently the beneficial owner of a total of
23,700,000 shares of WilTel common stock, representing 47.4% of the outstanding
shares of WilTel common stock.

    Pursuant to the Plan, 1,000,000 shares of WilTel common stock were issued on
the Effective Date to a securities holder channeling fund for purposes of
providing for the settlement of certain claims against WCG. To the extent that
these shares are not distributed to satisfy such claims, one-half of such unused
shares will be distributed to Leucadia and the other one-half will be
distributed to the holders of unsecured claims against WCG.

    In addition, pursuant to the Plan, on the Effective Date Leucadia and WilTel
entered into the Stockholders Agreement, the Registration Rights Agreement and
the Stockholder Rights and Co-Sale Agreement described under 'Interests of
Certain Persons in the Offer and Subsequent Merger -- Certain Agreements Between
Leucadia and WilTel'. Pursuant to the Stockholders Agreement and the Plan,
Leucadia designated four directors (including two independent directors) of
WilTel's nine-member board of directors (the other directors are the chief
executive officer of WilTel and four individuals designated by the Official
Committee of Unsecured Creditors of WCG).

THIS OFFER

    On May 15, 2003, Leucadia sent a letter (the 'May 2003 Letter') to the
WilTel Board of Directors (the 'WilTel Board') requesting that the WilTel Board
take action under WilTel's articles of incorporation and the Stockholders
Agreement to permit Leucadia to offer WilTel stockholders the opportunity to
exchange each share of WilTel common stock they hold for 0.3565 of a Leucadia
common share (this exchange ratio represented a 30% premium to WilTel's stock
price based on the respective per share closing prices of Leucadia ($38.65) and
WilTel ($10.60) on May 14, 2003). Leucadia did not request that the WilTel Board
recommend Leucadia's offer, only that the WilTel Board permit WilTel
stockholders the opportunity to decide whether or not they wished to accept
Leucadia's offer. The May 2003 Letter requested the WilTel Board to take action
under the Stockholders Agreement to permit Leucadia's offer to be presented to
WilTel stockholders because, as described under 'Interests of Certain Persons in
the Offer and Subsequent Merger -- Certain Agreements Between Leucadia and
WilTel', in the Stockholders Agreement, Leucadia agreed not to commence a tender
or exchange offer for WilTel shares prior to October 15, 2004 unless that
restriction was amended or waived by a majority of the independent directors of
WilTel (or by the holders of a majority of the WilTel shares not owned by
Leucadia). As described in greater detail below under ' -- Additional Factors
for Consideration

                                       22


by WilTel Stockholders -- Our Reasons for Making the Offer', our reason for
making the offer at this time was to acquire all of the WilTel common stock that
we do not own, and thereby (a) eliminate the potential for conflicts of interest
between Leucadia and WilTel, (b) eliminate the administrative, compliance and
other costs associated with maintaining WilTel's status as a public company and
(c) be able to consolidate WilTel in our federal income tax return and increase
the likelihood that WilTel's significant tax attributes will be utilized for the
benefit of shareholders.

    On May 27, 2003, the WilTel Board established a Special Committee comprised
of the six independent directors on the nine member WilTel Board. The Special
Committee interviewed a number of investment banking firms and law firms to aid
it in considering Leucadia's proposal before selecting JPMorgan as its financial
advisor and Gibson, Dunn & Crutcher LLP as its legal advisor. Leucadia had no
involvement in the selection or retention of the Special Committee's financial
and legal advisors.

    On July 11, 2003, Leucadia sent a letter to the Special Committee confirming
Leucadia's position mentioned at the May 27, 2003 WilTel Board meeting that
Leucadia 'has no interest in entertaining any offers to reduce its ownership
interest in WilTel'. On July 17, 2003, representatives of the Special Committee
met with representatives of Leucadia to commence the Special Committee's
financial due diligence review of Leucadia. On July 21, 2003, Leucadia executed
a confidentiality agreement with the Special Committee to facilitate the
provision of information about Leucadia.

    On July 25, 2003, Leucadia notified the Special Committee that 'shopping'
WilTel would be dangerous for the stability of WilTel's business because it
would create the impression that Leucadia was interested in selling its interest
in WilTel (which was not the case) after Leucadia had gone to considerable
effort to assure WilTel's customers, suppliers and employees that WilTel was a
long-term investment for Leucadia. Leucadia believed that market rumors of an
impending sale by Leucadia would undermine the stability and progress achieved
by WilTel following the turmoil of the bankruptcy process. Leucadia further
advised the Special Committee that its May 2003 proposal would be withdrawn if
the Special Committee or its advisors solicited offers for WilTel. On July 29,
2003, Leucadia withdrew its proposal and request set forth in the May 2003
Letter due to its concern that certain members of the Special Committee
expressed the view that WilTel needed to be 'shopped' for the Special Committee
to evaluate Leucadia's proposal by a market survey, even though Leucadia, as the
owner of 47.4% of the outstanding WilTel shares, had advised the Special
Committee that Leucadia had no intention of selling its shares and that,
therefore, a sale of WilTel to a third party was not realistic. Leucadia's
position that the Special Committee did not need to 'shop' WilTel in advance of
acting on Leucadia's proposal was based, among other things, on (i) the fact
that Leucadia's proposal for WilTel had been publicly disclosed since mid-May
2003 and, to Leucadia's knowledge, no competing transactions had been proposed,
(ii) the fact that WilTel would be able, at any time prior to the consummation
of Leucadia's offer, to respond to any unsolicited, bona fide superior proposal
that may be made by a third party for the acquisition of WilTel, and the WilTel
Board would be able to change its recommendation in respect of Leucadia's offer
if the Board determines that such action is necessary in order for the Board to
comply with its fiduciary duties under applicable law, (iii) Leucadia's belief
that, with the assistance of an experienced investment banking firm of the
caliber of JPMorgan, the Special Committee would be able to evaluate Leucadia's
offer through means other than a market check, and (iv) Leucadia's belief that
many acquisition transactions, particularly those where the subject company has
a significant stockholder, are conducted without a prior market check.

    On July 31, 2003, following Leucadia's withdrawal of its May 2003 proposal,
the Chairman of the WilTel Board sent a letter to the Special Committee
notifying its members that a special meeting of the WilTel Board was being
called to vote upon formally disbanding the Special Committee in light of the
fact that the Special Committee's mandate was predicated on Leucadia's May 2003
proposal, which had been withdrawn, as well as to take action with respect to
the return of non-public WilTel information that may have been disclosed to
third parties, and to confirm that no one is to 'shop' WilTel without
authorization of the WilTel Board. On August 1, 2003, members of the WilTel
Board communicated by telephone and reached a consensus to postpone the special
meeting of the WilTel Board to allow time for negotiations with respect to a
possible

                                       23


mutually-acceptable proposal to develop. No action to disband the Special
Committee was ever taken by the WilTel Board.

    Subsequent to Leucadia's withdrawal of its offer, the financial advisor to
the independent directors of WilTel contacted Leucadia to encourage Leucadia to
propose another offer. In response, on August 7, 2003 Leucadia sent a letter
(the 'August 2003 Letter') to the independent directors of WilTel relating to
alternative proposals to acquire the shares of WilTel not already owned by
Leucadia. The August 2003 Letter proposed either of the following transactions:
(A) an offer of 0.3672 of a Leucadia common share in exchange for each share of
WilTel common stock, if the independent directors of WilTel would agree to let
the offer go forward and not oppose the offer; or (B) a higher offer of 0.3934
of a Leucadia common share in exchange for each share of WilTel common stock, if
WilTel would enter into a mutually acceptable merger agreement with Leucadia
which provided for (i) a first-step exchange offer to be followed by a back-end
merger for the same consideration as offered in the exchange offer and (ii) a
recommendation in favor of the transaction by the independent directors of
WilTel. The August 2003 Letter fixed August 12 as the deadline for WilTel to
accept one of the proposals. These proposals were formulated by Leucadia without
negotiation with the Special Committee or their advisors. Representatives of
Leucadia and the independent directors' financial advisor held numerous
discussions over the next few days, during which they negotiated price, the
structure of the exchange ratio (i.e., floating vs. fixed rate and the
possibility of a 'collar') and, in response to a proposal by the independent
directors' financial advisor that the transaction consideration include the
possibility of contingent consideration for WilTel stockholders in the event
Leucadia were to sell all or substantially all of the business and assets of
WilTel within a short time after completing the proposed transaction for net
proceeds in excess of the valuation accorded to WilTel's equity in the proposed
transaction, the concept of CSRs.

    On August 12, 2003, following meetings between Leucadia and the Special
Committee's financial advisor, Leucadia and WilTel issued a joint press release
announcing that Leucadia and the Special Committee reached an agreement in
principle with respect to the offer and merger described in this prospectus. On
August 13, 2003, Weil, Gotshal & Manges LLP, our outside legal counsel, sent a
draft merger agreement to the Special Committee's outside legal counsel, Gibson,
Dunn & Crutcher LLP. Leucadia, the Special Committee and their respective
outside legal counsels began negotiating the merger agreement on August 18,
2003. Negotiations continued until the Merger Agreement was executed, following
its approval by the Special Committee and the WilTel Board, on August 21, 2003.

ADDITIONAL FACTORS FOR CONSIDERATION BY WILTEL STOCKHOLDERS

    OUR REASONS FOR MAKING THE OFFER

    We are making the offer for the purpose of acquiring all of the shares of
WilTel common stock that we do not own. Below are some of the key benefits we
hope to derive from the transactions:

     We believe that our ownership of 100% of WilTel would eliminate the
     potential for conflicts of interest between Leucadia and WilTel and would
     consequently allow us greater flexibility to focus resources on maximizing
     our investment in WilTel for the benefit of all shareholders. For example,
     we believe that WilTel may need additional financing in the future and that
     we might be a good source for that financing. Although in certain cases we
     might consider providing some of this financing for WilTel, the terms of
     such financing would need to be negotiated with WilTel's board of
     directors, and corporate governance concerns with respect to related-party
     transactions and concerns related to exploitation of corporate
     opportunities would factor into our decisions as to whether to propose or
     provide such financing. We believe that by eliminating those concerns
     through owning 100% of WilTel, we would be better able to focus our
     resources on maximizing for all shareholders the value of our investment in
     WilTel.

     If WilTel ceases to be a publicly held company, we would benefit from the
     elimination of administrative, compliance and other costs associated with
     maintaining WilTel's status as a public company. We estimate that these
     costs are approximately $6 million a year (including

                                       24


     the costs of directors and officers liability insurance for a public
     company). If WilTel remains a public company, we expect that some of these
     costs would increase in the future as a result of new regulations adopted
     under the Sarbanes-Oxley Act.

     WilTel and its subsidiaries currently have significant tax loss
     carry-forwards and other attractive tax attributes. As disclosed in
     WilTel's Annual Report on Form 10-K for the fiscal year ended December 31,
     2002, WilTel has reported $2.4 billion of federal net operating losses, of
     which $859.9 million, $1.4 billion and $126.2 million will expire in 2020,
     2021 and 2022, respectively; $297.7 million of estimated capital loss
     carryforwards, which will expire in 2005; and both foreign and state net
     operating losses that expire at various dates. Additionally, as at
     December 31, 2002, WilTel's reported tax basis in its property, plant and
     equipment was approximately $3.5 billion, which is significantly higher
     than the book value of those assets reflected in its financial statements;
     this tax basis is expected to generate substantial depreciation and
     amortization deductions for U.S. federal income tax purposes. Generally, by
     way of illustration only, assuming unlimited usability of tax losses and
     deductions and assuming an effective tax rate of 35%, a combination of $2.4
     billion of tax loss carryforwards and $3.5 billion of depreciable or
     amortizable tax basis could reduce tax liability over the years by as much
     as $2.065 billion. Portions of these attributes are or will be subject to
     reduction or limitation, and we do not believe, particularly given the many
     unknowns as to future income, events and tax law developments, that we can
     ascribe a true and accurate value to these tax attributes. However,
     Leucadia believes that its greater financial resources will provide greater
     opportunity for future investments, unlike WilTel, the cash resources of
     which are severely restricted and which is likely to need to raise capital
     to meet the debt service requirements of its existing debt in 2005.
     Moreover, Leucadia believes that it will be more likely to generate taxable
     income through its diversified interests than will WilTel, the operations
     of which are concentrated in one industry. Consequently, Leucadia believes
     that completion of the offer will increase the likelihood that WilTel's
     significant tax attributes will be utilized for the benefit of
     shareholders. See 'The Offer -- Tax Consolidation with WilTel'.

    IF YOU BECOME A SHAREHOLDER OF LEUCADIA AS A RESULT OF THE OFFER OR MERGER,
YOUR INVESTMENT SHOULD INDIRECTLY BENEFIT FROM ANY OF THE FOREGOING AS WELL AS
OTHER BENEFITS LEUCADIA MAY OBTAIN AS A RESULT OF THE TRANSACTIONS.

    OTHER FACTORS YOU SHOULD CONSIDER

    In deciding whether or not to tender your shares of WilTel common stock, you
should consider the factors described above under ' -- Our Reasons for Making
the Offer', as well as the factors set forth under 'Risk Factors' and the other
factors set forth in this prospectus. While we believe the offer should be
attractive to you as a WilTel stockholder, you should also consider the
following matters:

     As a stockholder of Leucadia, your interest in the performance and
     prospects of WilTel would only be indirect and in proportion to your share
     ownership in Leucadia. You therefore will not realize the same financial
     benefits of future appreciation in the value of WilTel, if any, that you
     may realize if the offer and the subsequent merger were not completed and
     you were to remain a WilTel stockholder.

     An investment in a company like WilTel, which concentrates in one industry,
     may be associated with greater risk and a greater potential for gain than
     an investment in a more diversified company like Leucadia. On the other
     hand, as a shareholder in a diversified company like Leucadia, your
     investment will be exposed to risks and events that are likely to have
     little or no effect on WilTel. You therefore would experience the impact of
     developments (both positive and negative) in the communications industry to
     a lesser extent, but would also experience the impact of developments (both
     positive and negative) in a variety of industries.

     The payment of additional Leucadia common shares in connection with the
     CSRs will be made only if and to the extent that Leucadia sells all or
     substantially all of WilTel's assets or more than 50% of WilTel's capital
     stock prior to the maturity date of the CSRs and the

                                       25


     net proceeds to Leucadia from such sale exceed the valuation accorded to
     WilTel's equity in the offer and merger. If Leucadia and WilTel do not
     ultimately consummate such a sale of WilTel's assets or capital stock prior
     to the maturity of the CSRs, the CSRs will become worthless, and Leucadia
     currently has no intention of engaging in any such sale.

    In addition to the foregoing, we are aware that individual stockholders of
WilTel have filed complaints in various courts purporting to commence class
action lawsuits on behalf of WilTel stockholders against WilTel, directors of
WilTel and Leucadia. Among other remedies, the complaints seek to enjoin the
offer and merger or, alternatively, rescission and damages in an unspecified
amount. Leucadia believes the complaints to be without merit but has entered
into an agreement in principle to settle the litigations in order to eliminate
the burden and expense of further litigation, subject to approval from directors
and officers insurance carriers, based upon increased disclosure in this
prospectus and the WilTtel Recommendation Statement. See 'Certain Legal Matters
and Regulatory Approvals -- Stockholder Litigation' for a more detailed
discussion of these lawsuits.

    CERTAIN INFORMATION PROVIDED

    It is our understanding that WilTel does not as a matter of course make
public any projections as to future performance, and the projections set forth
below are included in this prospectus only because this information was obtained
by Leucadia in connection with its existing stockholdings in WilTel. To
Leucadia's knowledge, the projections were not prepared with a view to public
disclosure or compliance with the published guidelines of the SEC or the
guidelines established by the American Institute of Certified Public Accountants
regarding projections or forecasts. It is Leucadia's belief that the projections
do not purport to present financial condition in accordance with accounting
principles generally accepted in the United States. WilTel's independent
accountants have not examined, compiled or otherwise applied procedures to the
projections and, accordingly, do not express an opinion or any other form of
assurance with respect to the projections. It is Leucadia's belief that the
projections were prepared for internal use and capital budgeting and other
management decisions and are subjective in many respects and thus susceptible to
interpretations and periodic revision based on actual experience and business
developments. It is also Leucadia's belief that the projections reflect numerous
assumptions made by management of WilTel with respect to industry performance,
general business, economic, market and financial conditions and other matters,
all of which are difficult to predict, many of which are beyond WilTel's
control. Accordingly, there can be no assurance that the assumptions made in
preparing the projections will prove accurate. It is expected that there will be
differences between actual and projected results, and actual results may be
materially greater or less than those contained in the projections. The
inclusion of the projections herein should not be regarded as an indication that
Leucadia or its affiliates or representatives considered or consider the
projections to be a reliable prediction of future events, and the projections
should not be relied upon as such.

    WilTel's projections, which were provided to the WilTel Board in June 2003
and do not reflect the offer and merger contemplated by this prospectus,
forecast total revenues of $1.28 billion, $1.50 billion and $1.72 billion for
2003, 2004 and 2005, respectively; net losses of ($198 million), ($133 million)
and ($3 million) for 2003, 2004 and 2005, respectively; and that during the
three year period ending December 31, 2005, WilTel would consume aggregate cash
resources of approximately $230 million, including scheduled principal
amortization of debt of $157 million.

    Neither Leucadia nor any of its affiliates or representatives has made or
makes any representation to any person regarding the ultimate performance of
WilTel or Leucadia compared to the projections, and (except as otherwise
required by applicable law) none of them undertakes any obligation to publicly
update the projections to reflect circumstances existing after the date when
made or to reflect the occurrence of future events, even in the event that any
or all of the assumptions underlying the projections are shown to be in error.

                 RECOMMENDATION OF WILTEL'S BOARD OF DIRECTORS

    On August 21, 2003, WilTel's board of directors, based upon the
recommendation of the Special Committee comprised of independent directors,
approved the Merger Agreement, this offer and the proposed merger. WilTel's
board of directors also has recommended that WilTel stockholders tender their
shares of WilTel common stock in this offer. For more information about the
WilTel board of directors' recommendation and the reasons for its
recommendation, please see WilTel's Solicitation/Recommendation Statement on
Schedule 14D-9 (the 'WilTel Recommendation Statement'). Please see 'Where You
Can Find More Information' to learn how to get a copy of the WilTel
Recommendation Statement.

    WilTel's board of directors has received a written opinion, dated
August 21, 2003, from JPMorgan to the effect that, as of the date of the opinion
and based on and subject to the matters described in the opinion, the
consideration to be received by the holders of WilTel common stock (other than
Leucadia and its affiliates) in the offer and merger is fair, from a financial
point of view, to such holders. We have been advised that JPMorgan did not
assign any monetary value to the CSRs in rendering its opinion. A summary of
JPMorgan's opinion and of the analysis performed, the bases and methods of
arriving at the opinion, and a description of JPMorgan's investigation and
assumptions, is included in the WilTel Recommendation Statement. The full text
of JPMorgan's written opinion, which sets forth, among other things, the
assumptions made, procedures followed, matters considered and limitations on the
review undertaken by JPMorgan in rendering its opinion, is attached to the
WilTel Recommendation Statement.

    In 2002 and 2001, Leucadia paid annual cash dividends of $0.25 per common
share. The payment of dividends in the future is subject to the discretion of
Leucadia's board of directors and will depend upon general business conditions,
legal and contractual restrictions on the payment of dividends and other factors
that our board of directors may deem to be relevant. In connection with the
declaration of dividends or the making of distributions on, or the purchase,
redemption or other acquisition of Leucadia common shares, Leucadia is required
to comply with certain restrictions contained in certain of its debt
instruments. Leucadia's regulated subsidiaries are restricted in the amount of
distributions that can be made to Leucadia without regulatory approval. Leucadia
may consider the recent changes in U.S. tax laws lowering the tax rate on
dividends in determining its dividend policy.

    The following dividend information concerning WilTel was obtained from
WilTel's Annual Report on Form 10-K for the fiscal year ended December 31, 2002.
WilTel's current debt agreements prohibit WilTel from paying cash dividends on
WilTel common stock. No common stock cash dividends were paid in 2002 and WilTel
management does not expect to pay cash dividends on the common stock in the
foreseeable future. It is WilTel management's intention to retain future
earnings, if any, to finance the operation and development of WilTel's business.
Future dividends, if any, will be determined by WilTel's board of directors and
will depend on the success of operations, capital needs, financial conditions,
restrictions on the payment of dividends contained in WilTel's debt agreements
and other such factors as WilTel's board of directors may consider.

                                   THE OFFER

    We are proposing to acquire all of the outstanding shares of WilTel common
stock that we do not already own. We currently beneficially own 23,700,000
shares of WilTel common stock, representing 47.4% of the outstanding shares of
WilTel common stock.

EXCHANGE OF SHARES OF WILTEL COMMON STOCK

    We are offering to exchange 0.4242 of a Leucadia common share and one CSR
for each outstanding share of WilTel common stock validly tendered and not
properly withdrawn prior to the expiration of the offer, upon the terms and
subject to the conditions set forth in this prospectus and the related letter of
transmittal. For a description of the CSRs, please see 'Description of the
CSRs'. We will not acquire any shares of WilTel common stock in the offer unless
WilTel stockholders (other than Leucadia and its affiliates) have validly
tendered and not properly withdrawn prior to the expiration of the offer a
majority of the outstanding shares of WilTel common stock not owned by Leucadia
and its affiliates. If none of the shares of WilTel common stock currently held
by the securities holder channeling fund established in connection with the
reorganization of WilTel's predecessor company are validly tendered in
accordance with the terms of the offer, then the shares of WilTel common stock
in such fund will be deemed not outstanding for purposes of this minimum
condition. As of the date of this prospectus, 26,300,000 of the outstanding
shares of WilTel common stock were not owned by Leucadia and its affiliates.
There are also other conditions to the offer that are described under
' -- Conditions of the Offer'.

    After completion of the offer, Leucadia will have WilTel complete a merger
with Merger Sub, in which each outstanding share of WilTel common stock (except
for shares beneficially owned directly or indirectly by Leucadia for its own
account) will be converted into the right to receive Leucadia common shares and
a CSR at the same exchange ratio as used in the offer, subject to dissenters'
rights to the extent applicable under Nevada law. If after the completion of
this offer we beneficially own more than 90% of the outstanding shares of WilTel
common stock, we may effect this merger without the approval of WilTel
stockholders, as permitted under Nevada law. See ' -- Approval of the Merger'.

    When we refer to the expiration of the offer we mean 5:00 PM, New York City
time, on Wednesday, November 5, 2003, unless we extend the period of time for
which the offer is open, in which case the offer will expire, and references to
the expiration of the offer will mean, the latest time and date on which the
offer is open.

    If you are the record owner of your shares and you tender your shares
directly to the exchange agent and depository, you will not be obligated to pay
any charges or expenses of the exchange agent and depository or any brokerage
commissions. If you own your shares through a broker or other nominee, and your
broker or nominee tenders the shares on your behalf, your broker or nominee may
charge you a fee for doing so. You should consult your broker or nominee to
determine whether any charges will apply.

TIMING OF THE OFFER

    We commenced the offer on September 4, 2003. The offer is scheduled to
expire at 5:00 PM, New York City time, on Wednesday, November 5, 2003, unless we
extend the period of the offer. All references to the expiration of the offer
mean the time of expiration, as extended. For more information, see the
discussion under ' -- Extension, Termination and Amendment' immediately below.

EXTENSION, TERMINATION AND AMENDMENT

    If any condition to the offer is not satisfied or, if permissible, waived,
on any scheduled expiration date of the offer, then we may extend the expiration
date from time to time. Each extension may last for no more than ten business
days, unless WilTel and Leucadia agree in writing to allow for a longer period.
We also have the right to extend the offer for any period of

                                       30


time required by the applicable rules and regulations of the SEC. Leucadia or
WilTel can terminate the Merger Agreement if the offer is not consummated by
January 15, 2004. We can extend the offer by giving oral or written notice of
extension to American Stock Transfer & Trust Company, the exchange agent and
depository for the offer. If we decide to extend the offer, we will make an
announcement to that effect no later than 9:00 a.m., New York City time, on the
next business day after the previously scheduled expiration. We are not giving
any assurance that we will extend the offer. During any extension, all shares of
WilTel common stock previously tendered and not withdrawn will remain deposited
with the exchange agent and depository, subject to your right to withdraw your
shares of WilTel common stock as described under ' -- Withdrawal Rights'.

    We reserve the right to make any changes in the terms and conditions of the
offer by giving oral or written notice of the change to the exchange agent and
depository and by making a public announcement. However, without the prior
written consent of WilTel, we cannot:

     decrease the exchange ratio or decrease the number of Leucadia common
     shares issuable pursuant to the CSRs;

     make any changes to the form or consideration to be paid for shares of
     WilTel common stock in the offer;

     impose any additional conditions on the offer other than those already
     described in the Merger Agreement;

     amend or waive the minimum condition or the tax opinion condition as
     described in the Merger Agreement; or

     make any other change to the terms and conditions of the offer which is
     adverse to the holders of shares of WilTel common stock.

    We are required to follow any extension, termination, amendment or delay, as
promptly as practicable, with a public announcement. In the case of an
extension, the announcement is required to be issued no later than 9:00 a.m.,
New York time, on the next business day after the previously scheduled
expiration date. Subject to applicable law, and without limiting the manner in
which we may choose to make any public announcement, we assume no obligation to
publish, advertise or otherwise communicate any public announcement other than
by making a release to the Dow Jones News Service.

    If we make a material change in the terms of the offer or the information
concerning the offer, or if we waive a material condition of the offer, we will
extend the offer to the extent required under the Exchange Act.

PROCEDURE FOR TENDERING SHARES

    For you to validly tender shares of WilTel common stock into the offer, you
must do one of the following:

     Deliver certificates for your shares, a properly completed and duly
     executed letter of transmittal or a duly executed copy thereof, along with
     any other required documents, to the exchange agent and depository at one
     of its addresses set forth on the back cover of this prospectus prior to
     the expiration of the offer;

     Arrange for a book-entry transfer of your shares to be made to the exchange
     agent and depository's account at DTC and receipt by the exchange agent and
     depository of a confirmation of this transfer prior to the expiration of
     the offer, and the delivery of a properly completed and duly executed
     letter of transmittal or a duly executed copy thereof, and any other
     required documents, to the exchange agent at one of its addresses set forth
     on the back cover of this prospectus prior to the expiration of the offer;
     or

     Arrange for a book-entry transfer of your shares to the exchange agent and
     depository's account at DTC and receipt by the exchange agent and
     depository of confirmation of this transfer, including an 'agent's
     message,' prior to the expiration of the offer.

                                       31


    These deliveries and arrangements must be made before the expiration of the
offer. TENDERS BY NOTICE OF GUARANTEED DELIVERY WILL NOT BE ACCEPTED. The term
'agent's message' means a message, transmitted by DTC to, and received by, the
exchange agent and depository and forming a part of a book-entry confirmation,
which states that DTC has received an express acknowledgment from the
participant in DTC tendering the shares of WilTel common stock which are the
subject of the book-entry confirmation, that the participant has received and
agrees to be bound by the terms of the letter of transmittal and that we may
enforce that agreement against the participant.

    The exchange agent and depository will establish an account with respect to
the shares of WilTel common stock at DTC for purposes of the offer within two
business days after the date of the distribution of this prospectus, and any
financial institution that is a participant in DTC may make book-entry delivery
of the shares of WilTel common stock by causing DTC to transfer these shares of
WilTel common stock into the exchange agent and depository's account in
accordance with DTC's procedure for the transfer. For a tender made by transfer
of shares of WilTel common stock through book-entry delivery at DTC to be valid,
the exchange agent and depository must receive, prior to the expiration of the
offer, a book-entry confirmation of transfer and either a duly executed letter
of transmittal or a duly executed copy thereof, along with any other required
documents, at one of its addresses set forth on the back cover of this
prospectus, or an agent's message as part of the book-entry confirmation.
Signatures on all letters of transmittal must be guaranteed by an eligible
institution, except in cases in which shares of WilTel common stock are tendered
either by a registered holder of shares of WilTel common stock who has not
completed the box entitled 'Special Delivery Instructions' on the letter of
transmittal or for the account of an eligible institution. By 'eligible
institution' we mean a bank, broker, dealer, credit union, savings association
or other entity which is a member in good standing of a recognized Medallion
Program approved by the Securities Transfer Association Inc., including the
Securities Transfer Agent's Medallion Program (STAMP), the Stock Exchange
Medallion Program (SEMP) and the New York Stock Exchange Medallion Signature
Program (MSP), or any other 'eligible guarantor institution,' as that term is
defined in Rule 17Ad-15 under the Exchange Act.

    If the certificates for shares of WilTel common stock are registered in the
name of a person other than the person who signs the letter of transmittal, the
certificates must be endorsed or accompanied by appropriate stock powers, in
either case signed exactly as the name or names of the registered owner or
owners appear on the certificates, with the signature(s) on the certificates or
stock powers guaranteed in the manner described above.

    The method of delivery of certificates representing shares of WilTel common
stock and all other required documents, including delivery through DTC, is at
your option and risk, and the delivery will be deemed made only when actually
received by the exchange agent and depository. If delivery is by mail, we
recommend registered mail with return receipt requested, properly insured. In
all cases, you should allow sufficient time to ensure timely delivery before
expiration of the offer.

WITHDRAWAL RIGHTS

    You may withdraw shares of WilTel common stock that you tender pursuant to
the offer at any time before the expiration of the offer. After the expiration
of the offer, tenders are irrevocable. However, if we have not accepted tendered
shares for exchange by November 3, 2003, you may withdraw tendered shares at any
time thereafter.

    For your withdrawal to be effective, the exchange agent and depository must
receive from you, prior to the expiration of the offer, a written or facsimile
transmission notice of withdrawal at one of its addresses set forth on the back
cover of this prospectus, and your notice must include your name, address,
social security number, the certificate number(s) and the number of shares of
WilTel common stock to be withdrawn, as well as the name of the registered
holder, if it is different from that of the person who tendered those shares of
WilTel common stock. If shares of WilTel common stock have been tendered
pursuant to the procedures for book-entry tender discussed above under
' -- Procedure for Tendering Shares,' any notice of withdrawal must specify

                                       32


the name and number of the account at DTC to be credited with the withdrawn
shares of WilTel common stock and must otherwise comply with DTC's procedures.
If certificates have been delivered or otherwise identified to the exchange
agent and depository, the name of the registered holder and the serial numbers
of the particular certificates evidencing the shares of WilTel common stock
withdrawn must also be furnished to the exchange agent and depository, as stated
above, prior to the physical release of the certificates. We will decide all
questions as to the form and validity (including time of receipt) of any notice
of withdrawal, in our sole discretion, and our decision will be final and
binding.

    An eligible institution must guarantee all signatures on the notice of
withdrawal unless the shares of WilTel common stock have been tendered for the
account of an eligible institution.

    None of Leucadia, the exchange agent and depository, the information agent
or any other person will be under any duty to give notification of any defects
or irregularities in any notice of withdrawal or will incur any liability for
failure to give any notification. Any shares of WilTel common stock that you
properly withdraw will be deemed not to have been validly tendered for purposes
of the offer. However, you may retender withdrawn shares of WilTel common stock
by following one of the procedures discussed under ' -- Procedure for Tendering
Shares' at any time before the expiration of the offer.

SUBSEQUENT OFFERING PERIOD

    We may elect to provide a subsequent offering period of up to 20 business
days after the acceptance of shares of WilTel common stock in the offer if the
requirements of Rule 14d-11 under the Exchange Act have been met. You will not
have the right to withdraw any shares of WilTel common stock that you tender
during the subsequent offering period. We are required to accept for exchange,
and to deliver Leucadia common shares in exchange for, shares of WilTel common
stock that are validly tendered, promptly after they are tendered during any
subsequent offering period. If we elect to provide a subsequent offering period,
we are required to make a public announcement to that effect no later than 9:00
a.m., New York time, on the next business day after the previously scheduled
expiration date.

EFFECT OF A TENDER OF SHARES

    By executing a letter of transmittal, you will agree and acknowledge that
our acceptance for exchange of shares of WilTel common stock you tender in the
offer will, without any further action, revoke any prior powers of attorney and
proxies that you may have granted in respect of those shares and you will not
grant any subsequent proxies and, if any are granted, they will not be deemed
effective. We reserve the right to require that, in order for shares of WilTel
common stock to be validly tendered, we must be able to exercise full voting,
consent and other rights with respect to those shares of WilTel common stock
immediately upon our acceptance of those shares of WilTel common stock for
exchange.

    We will determine questions as to the validity, form, eligibility (including
time of receipt) and acceptance for exchange of any tender of shares of WilTel
common stock, in our sole discretion, and our determination will be final and
binding. We reserve the absolute right to reject any and all tenders of shares
of WilTel common stock that we determine are not in proper form or the
acceptance of or exchange for which may, in the opinion of our counsel, be
unlawful. No tender of shares of WilTel common stock will be deemed to have been
validly made until all defects and irregularities in tenders of those shares
have been cured or waived. None of Leucadia, the exchange agent and depository,
the information agent, nor any other person will be under any duty to give
notification of any defects or irregularities in the tender of any shares of
WilTel common stock or will incur any liability for failure to give any such
notification. Our interpretation of the terms and conditions of our offer,
including the letter of transmittal and instructions, will be final and binding.

                                       33


    The tender of shares of WilTel common stock pursuant to any of the
procedures described above will constitute a binding agreement between you and
us upon the terms and subject to the conditions of the offer.

DELIVERY OF LEUCADIA COMMON SHARES

    Upon the terms and subject to the conditions of the offer, including, if the
offer is extended or amended, the terms and conditions of the extension or
amendment, we will, promptly after expiration of the offer, exchange shares of
WilTel common stock validly tendered and not properly withdrawn for Leucadia
common shares, CSRs and cash instead of fractional shares. CSRs will not be
evidenced by any form of certificate. In all cases, exchange of shares of WilTel
common stock tendered and accepted for exchange pursuant to the offer will be
made only if the exchange agent and depository timely receives (1) certificates
for those shares of WilTel common stock, or a timely confirmation of a
book-entry transfer of those shares of WilTel common stock in the exchange agent
and depository's account at DTC, and a properly completed and duly executed
letter of transmittal or a duly executed copy thereof, and any other required
documents; or (2) a timely confirmation of a book-entry transfer of those shares
of WilTel common stock in the exchange agent and depository's account at DTC,
together with an 'agent's message' as described under ' -- Procedure for
Tendering Shares'.

    For purposes of the offer, we will be deemed to have accepted for exchange
shares of WilTel common stock validly tendered and not properly withdrawn when,
as and if we notify the exchange agent and depository of our acceptance of the
tender of those shares of WilTel common stock pursuant to the offer. The
exchange agent and depository will deliver Leucadia common shares in exchange
for shares of WilTel common stock pursuant to the offer and cash instead of a
fraction of a Leucadia common share promptly after receipt of our notice. The
exchange agent and depository will act as agent for tendering WilTel
stockholders for the purpose of receiving Leucadia common shares and cash
instead of a fraction of a Leucadia common share and transmitting the shares and
cash to you. You will not receive any interest on any cash that you are entitled
to receive, even if there is a delay in making the exchange.

    If we do not accept shares of WilTel common stock for exchange pursuant to
the offer or if certificates are submitted for more shares of WilTel common
stock than are tendered into the offer, we will return certificates for these
unexchanged shares of WilTel common stock without expense to the tendering
stockholder. If we do not accept shares of WilTel common stock for exchange
pursuant to the offer, shares of WilTel common stock tendered by book-entry
transfer into the exchange agent and depository's account at DTC pursuant to the
procedures set forth under ' -- Procedure for Tendering Shares' will be credited
to the account maintained with DTC from which those shares were originally
transferred, promptly following expiration or termination of the offer.

CASH INSTEAD OF FRACTIONAL LEUCADIA COMMON SHARES

    We will not issue any fraction of a Leucadia common share pursuant to the
offer or the merger. In lieu thereof, Leucadia will arrange for the exchange
agent and depository to act on behalf of WilTel stockholders who would otherwise
be entitled to fractional shares to promptly after completion of the offer
aggregate these fractional interests and sell the Leucadia common shares in
respect thereof at the then prevailing prices on the open market. Sales will be
executed in round lots to the extent practicable. There can be no assurance as
to the sales price that the exchange agent and depository will receive for such
shares. Promptly after completing the sale of all of such shares, the exchange
agent and depository will make a cash payment (without interest) equal to the
proportionate interest in the net proceeds from the sale of such shares
attributable to each WilTel stockholder otherwise entitled to fractional shares.

                                       34


CONDITIONS OF THE OFFER

    The offer is subject to a number of conditions, which we describe below.
Notwithstanding any other provision of the offer, Leucadia shall not be required
to accept for payment or, subject to any applicable rules and regulations of the
SEC, including Rule 14e-l(c) under the Exchange Act (relating to Leucadia's
obligation to pay for or return tendered shares of WilTel common stock promptly
after termination or withdrawal of the offer), pay for, and may delay the
acceptance for payment of or, subject to the restriction referred to above, the
payment for, any tendered shares of WilTel common stock, and (subject to the
provisions of the Merger Agreement) may terminate the offer and not accept for
payment any tendered shares if any of these conditions are not satisfied or,
where permissible, waived as of the expiration of the offer.

    MINIMUM CONDITION

    There must be validly tendered and not properly withdrawn prior to the
expiration of the offer a majority of the shares of WilTel common stock not
owned by Leucadia and its affiliates. As of the date of this prospectus, there
were 26,300,000 shares of WilTel common stock outstanding that are not owned by
Leucadia and its affiliates. If none of the 1,000,000 shares of WilTel common
stock currently held by the securities holder channeling fund established in
connection with the reorganization of WilTel's predecessor company are validly
tendered in accordance with the terms of the offer, then the shares of WilTel
common stock in such fund will be deemed not outstanding for purposes of this
minimum condition. We will not waive this condition without the consent of
WilTel.

    REGISTRATION STATEMENT EFFECTIVENESS CONDITION

    The registration statement on Form S-4 of which this prospectus is a part
must have become effective under the Securities Act and not be the subject of
any stop order or proceedings seeking a stop order.

    ANTITRUST CONDITION

    Any applicable waiting periods under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the 'HSR Act'), must have expired or been
terminated.

    REGULATORY CONDITION

    Leucadia shall have received all required approvals from the Federal
Communications Commission and state regulatory authorities for the change of
control of WilTel.

    NYSE LISTING CONDITION

    The Leucadia common shares issuable in exchange for shares of WilTel common
stock in the offer and the merger shall have been approved (if such approval is
necessary) for listing on the New York Stock Exchange.

    TAX OPINION CONDITION

    WilTel shall have received a written opinion from Weil, Gotshal & Manges LLP
(or, if not Weil, Gotshal & Manges LLP, Gibson, Dunn & Crutcher LLP) to the
effect that the offer and the merger should constitute a reorganization within
the meaning of Section 368(a) of the Internal Revenue Code (which opinion may
rely on such assumptions and representations as such counsel reasonably deems
appropriate). We will not waive this condition without the consent of WilTel.

    ADDITIONAL CONDITIONS

    In addition, Leucadia shall not be required to accept for payment or,
subject to any applicable rules and regulations of the SEC, including
Rule 14e-l(c) under the Exchange Act (relating to

                                       35


Leucadia's obligation to pay for or return tendered shares of WilTel common
stock promptly after termination or withdrawal of the offer), pay for, and may
delay the acceptance for payment of or, subject to the restriction referred to
above, the payment for, any tendered shares of WilTel common stock, and (subject
to the provisions of the Merger Agreement) may terminate the offer and not
accept for payment any tendered shares if at any time prior to the expiration of
the offer, any of the following conditions exist:

    issued or entered by any governmental entity that (i) restrains, enjoins,
    prevents, prohibits or makes illegal the acceptance for payment, payment for
    or purchase of some or all of the shares of WilTel common stock by Leucadia
    or the consummation of the transactions contemplated by the Merger
    Agreement, including the offer and the merger (collectively, the
    'Transactions'), (ii) imposes material limitations on the ability of
    Leucadia or any of its affiliates effectively to exercise full rights of
    ownership of 100% of the shares of WilTel common stock, including, without
    limitation, the right to vote the shares of WilTel common stock purchased by
    them on all matters properly presented to WilTel's stockholders on an equal
    basis with all other stockholders (including, without limitation, the
    adoption of the Merger Agreement and approval of the Transactions),
    (iii) restrains, enjoins, prevents, prohibits or makes illegal, or imposes
    material limitations on, Leucadia's or any of its affiliates' ownership or
    operation of all or any portion of the businesses and assets of WilTel and
    its subsidiaries, or, as a result of the Transactions, of Leucadia and its
    subsidiaries, (iv) compels Leucadia or any of its affiliates to dispose of
    any shares of WilTel common stock or, as a result of the Transactions,

    its subsidiaries, or (v) imposes damages on Leucadia, WilTel or any of their
    respective affiliates as a result of the Transactions in amounts that are

    routine application of the waiting period provisions of the HSR Act) that
    results, or is reasonably likely to result, directly or indirectly, in any
    of the consequences referred to in paragraph (a) above;

        (c) (i) there shall have occurred any events or changes that,
    individually or in the aggregate, have had or would reasonably be expected
    to have a Company Material Adverse Effect (as defined in the Merger
    Agreement) or (ii) (A) the representations and warranties of WilTel set
    forth in the Merger Agreement that are qualified as to 'materiality' or
    'Material Adverse Effect' shall not be true and correct, or the
    representations and warranties of WilTel set forth in the Merger Agreement
    that are not so qualified shall not be true and correct in all material
    respects, in each case, at and as of the date of such determination as if
    made on such date (other than those representations and warranties that
    address matters only as of a particular date which are true and correct as
    of such date), or (B) WilTel shall have breached or failed in any material
    respect to perform or comply with any obligation, agreement or covenant
    required by the Merger Agreement to be performed or complied with by it;

    securities on the New York Stock Exchange, the American Stock Exchange or in

    at the time of the commencement of the offer, a material acceleration or
    worsening thereof; or

        (f) the Merger Agreement shall have been terminated in accordance with
    its terms or the offer shall have been terminated with the consent of
    WilTel.

    GENERAL

    All of the foregoing conditions are for our sole benefit and may be asserted
by us regardless of the circumstances giving rise to any such conditions or
(except as otherwise provided in the Merger Agreement) may be waived by us in
whole or in part at any time and from time to time in our sole discretion prior
to the expiration of the offer. The determination as to whether any condition
has occurred or has been satisfied will be in our judgment and will be final and
binding on all parties. Any failure by us at any time to exercise any of the
foregoing rights shall not be deemed a waiver of any such right, the waiver of
any such right with respect to any particular facts or circumstances shall not
be deemed a waiver with respect to any other facts or circumstances, and each
such right shall be deemed an ongoing right which may be asserted at any time
and from time to time prior to the expiration of the offer.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

    The following discussion describes the material United States federal income
tax consequences for WilTel stockholders of the offer and merger. It is based
upon the Internal Revenue Code of 1986, as amended (which we refer to as the
Code), regulations under the Code, and court and administrative rulings and
decisions in effect on the date of this prospectus, all of which are subject to
change, possibly retroactively. Any change could affect the continuing validity
of the tax consequences described in this prospectus. Leucadia has received an
opinion from Weil, Gotshal & Manges LLP that the following, insofar as it
constitutes statements of law or legal conclusions and except to the extent
qualified therein and herein, are the material U.S. federal income tax
consequences to WilTel stockholders of the offer and merger.

    The description applies only to WilTel stockholders who are U.S. persons.
For purposes of this description, the term 'U.S. person' means any person that
is for U.S. federal income tax purposes: (a) an individual who is a U.S. citizen
or a U.S. resident alien; (b) any entity that is created or organized under the
laws of the United States or any State and is treated as a corporation; (c) a
trust (i) in respect of which a U.S. court is able to exercise primary
supervision over the administration of the trust and one or more U.S. persons
have the authority to control all substantive decisions of the trust or
(ii) that was in existence on August 20, 1996, and validly elected to continue
to be treated as a domestic trust; or (d) an estate that is subject to U.S. tax
on its worldwide income from all sources.

    Our description is not a comprehensive description of all the tax
consequences that may be relevant to you. It applies only to WilTel stockholders
who hold their shares of WilTel common stock as a capital asset. Further, it
assumes that both the offer and the subsequent merger are completed as described
in this prospectus and that all conditions to closing the offer and the merger
as set forth in this prospectus are satisfied without waiver. No attempt has
been made to address all United States federal income tax consequences that may
be relevant to a particular WilTel stockholder in light of the stockholder's
individual circumstances or to WilTel stockholders who are subject to special
treatment under the United States federal income tax laws, such as: banks,
insurance companies and financial institutions; tax-exempt organizations; mutual
funds; persons that have a functional currency other than the U.S. dollar;
investors in pass-through entities (including partnerships); traders in
securities who elect to apply a mark-to-market method of accounting; dealers in
securities or foreign currencies; holders of options granted by WilTel; WilTel
stockholders who are not U.S. persons; and WilTel stockholders who hold shares
of WilTel common stock as part of a hedge, straddle, constructive sale or
conversion transaction.

    This description does not address any tax consequences arising under the
laws of any state, locality or foreign jurisdiction, and it does not address any
federal tax consequences other than

                                       37


federal income tax consequences. Nor does it address the tax consequences of any
transaction other than the offer and the merger.

    The tax consequences to WilTel stockholders who tender or surrender their
shares of WilTel common stock in the offer or the merger in exchange for
Leucadia common shares depend on whether the offer and merger constitute a
reorganization within the meaning of Section 368(a) of the Code. WilTel has
received an opinion from Weil, Gotshal & Manges LLP that the offer and merger
should qualify as a reorganization for United States federal income tax
purposes. The opinion is based on representations by Leucadia and WilTel and on
an assessment of prior and potential future transactions and is intended to
convey a high degree of likelihood (without the ability to conclude with
certainty if the offer and merger are challenged by the IRS) that the offer and
merger will so qualify. Assuming that the offer and merger qualify as a
reorganization within the meaning of Section 368(a) of the Code, then, in
general:

     a WilTel stockholder will not recognize any gain or loss on the exchange of
     shares of WilTel common stock for Leucadia common shares and CSRs in the
     offer or the subsequent merger, except with respect to cash, if any,
     received by the stockholder instead of a fractional Leucadia common share;

     subject to the discussion below regarding the CSRs, the aggregate tax basis
     to a WilTel stockholder of the Leucadia common shares received in exchange
     for shares of WilTel common stock pursuant to the offer or the merger will
     equal the WilTel stockholder's aggregate tax basis in the shares of WilTel
     common stock surrendered, decreased by the amount of any tax basis
     allocable to any fractional Leucadia common share for which cash is
     received;

     subject to the discussion below regarding the CSRs, the holding period of a
     WilTel stockholder for the Leucadia common shares received pursuant to the
     offer or the merger will include the holding period of the shares of WilTel
     common stock surrendered in exchange therefor; and

     a WilTel stockholder who receives cash instead of a fractional Leucadia
     common share pursuant to the offer or the subsequent merger will recognize
     gain or loss on the exchange in an amount equal to the difference between
     the amount of cash received and the basis of his shares of WilTel common
     stock allocable to the fractional share. The gain or loss generally will
     constitute capital gain or loss, long term if the shares of WilTel common
     stock exchanged therefor had been held for the applicable long term holding
     period. The deductibility of capital losses is subject to limitations for
     both individuals and corporations.

    If you receive Leucadia common shares under CSRs, a certain portion of those
shares may be treated for federal income tax purposes as taxable interest
income. The portion of any Leucadia common shares treated as interest will have
a basis equal to the amount of interest required to be recognized and the
holding period of such portion will begin on the day after receipt of such
shares.

    Certain other tax consequences resulting from your right to the receipt of
additional Leucadia common shares pursuant to the CSRs are not clear. While not
free from doubt, it is likely that in allocating the aggregate tax basis in your
shares of WilTel common shares to the Leucadia common shares received upon
consummation of the offer or the merger, you will be required to assume that you
will receive the maximum number of Leucadia common shares under the CSRs you
receive. While other allocation methodologies may be permitted, this method of
allocating basis will result, at least initially, in an allocation of less of
your basis to the Leucadia common shares you receive at the time of the offer or
the merger. After your initial allocation of basis, you may be required to
reallocate the basis among your Leucadia common shares if actual results of the
CSR differ from the assumptions you made in your initial allocation. Because the
mechanics of such subsequent basis adjustment are complex and the law governing
such an adjustment is unsettled, you should consult your own tax advisor with
respect to the calculation of tax basis in the Leucadia shares received.

    A WilTel stockholder who receives cash for all its shares of WilTel common
stock pursuant to the exercise of appraisal rights, if any, generally will
recognize gain or loss equal to the difference

                                       38


between the tax basis of the shares of WilTel common stock surrendered and the
amount of cash received, except that any cash received that is or is deemed to
be interest for federal income tax purposes will be taxed as ordinary income. A
WilTel stockholder receiving cash pursuant to the exercise of appraisal rights
may be required to recognize gain or loss in the year the merger closes,
irrespective of whether the stockholder actually receives payment for its shares
of WilTel common stock in that year.

    Although WilTel has received an opinion from Weil, Gotshal & Manges LLP that
the offer and merger should qualify as a reorganization under Section 368(a) of
the Code, WilTel stockholders should be aware that the tax consequences are not
entirely free from doubt and we have not requested and will not request an
advance ruling from the IRS as to the tax consequences of the offer or merger.
In the event that the IRS were successfully to challenge the tax-free
reorganization treatment of the offer and merger, you would recognize gain or
loss in the offer or merger equal to the difference between your tax basis of
the shares of WilTel common stock surrendered and your amount realized in the
offer or merger. Your amount realized would include the fair market value of the
Leucadia common shares you receive in the offer or merger (other than Leucadia
common shares received under CSRs, which are discussed below) as well as cash
received in lieu of fractional share interests in Leucadia common shares. Your
tax basis in the Leucadia common shares received in the offer and merger (except
with respect to Leucadia common shares received under CSRs) would be equal to
their fair market value and your holding period for such shares would begin on
the day following receipt of such shares.

    Moreover, in the event that the IRS successfully challenged the
characterization of the offer and merger as a reorganization, it is unclear
whether your amount realized in the offer or merger would include (i) the fair
market value of the CSRs you receive or, alternatively, (ii) the fair market
value of any Leucadia common shares you actually receive under the CSRs (less
any portion of such shares treated as interest for U.S. federal income tax
purposes). A portion of the Leucadia common shares, if any, that you receive
under the CSRs may be treated as taxable interest income for U.S. federal income
tax purposes and your basis and holding period in such portion would be as
described above.

    This description is not binding on the IRS, and there can be no assurance
that the IRS will not disagree with or challenge any of the conclusions
described herein. ACCORDINGLY, EACH WILTEL STOCKHOLDER IS URGED TO CONSULT WITH
A TAX ADVISOR TO DETERMINE THE PARTICULAR FEDERAL, STATE, LOCAL OR FOREIGN
INCOME OR OTHER TAX CONSEQUENCES OF THE OFFER AND MERGER TO THE STOCKHOLDER,
INCLUDING TAX RETURN REPORTING REQUIREMENTS AND THE EFFECT OF ANY PROPOSED
CHANGES IN THE TAX LAWS.

TAX CONSOLIDATION WITH WILTEL; WILTEL TAX ATTRIBUTES

    As disclosed in WilTel's Annual Report on Form 10-K for the fiscal year
ended December 31, 2002, WilTel has reported $2.4 billion of federal net
operating losses, of which $859.9 million, $1.4 billion and $126.2 million will
expire in 2020, 2021 and 2022, respectively; $297.7 million of estimated capital
loss carryforwards, which will expire in 2005; and $71.2 million of foreign net
operating losses, as well as various state net operating losses, that expire at
various dates. Additionally, WilTel has a tax basis in its assets that is
significantly higher than the book value of those assets reflected in its
financial statements; this high tax basis is expected to generate substantial
depreciation and amortization deductions for federal income tax purposes. As a
result of these favorable tax attributes, it is likely that WilTel will pay
little or no federal income taxes for the foreseeable future. The ultimate
utilization of WilTel's tax attributes will depend upon a number of factors,
including future operating results, tax law changes and the expiration of
carryforward periods. See 'Background and Reasons for the Offer and Subsequent
Merger -- Additional Factors for Consideration by WilTel Stockholders -- Our
Reasons for Making the Offer'.

    If the offer and merger are completed, WilTel would be consolidated with
Leucadia in its federal income tax return. Under the tax rules governing
consolidated groups, WilTel and its subsidiaries would be segregated for certain
purposes into a subgroup within the Leucadia consolidated group, and WilTel's
significant tax attributes would continue to be available to offset any future
income generated by the WilTel subgroup. To the extent that WilTel's tax loss
carryforwards are attributable to periods prior to WilTel's consolidation within
the Leucadia group,

                                       39


such excess will not be available to offset taxable income of other members of
the Leucadia consolidated group other than income attributable to the WilTel
subgroup. In addition, to the extent that the tax basis of WilTel's assets
exceed their fair market value when WilTel joins Leucadia's consolidated tax
group, future tax deductions related to such excess will not be available to
offset taxable income of members of the Leucadia consolidated group other than
members of the WilTel subgroup. Any other future deductions and losses
attributable to the WilTel subgroup should be available to offset taxable income
of the entire Leucadia consolidated group, and would not be limited to offset
only income generated by the WilTel subgroup.

TRANSFERABILITY OF LEUCADIA COMMON SHARES

    The Leucadia common shares offered hereby will be registered under the
Securities Act and listed on The New York Stock Exchange. Accordingly, such
shares may be traded freely subject to (1) restrictions under Leucadia's
certificate of incorporation applicable to 5% shareholdings (see, 'Risk
Factors -- Leucadia Common Shares are Subject to Transfer Restrictions') and (2)
restrictions under the Securities Act applicable to subsequent transfers of our
shares by 'affiliates' (as defined in the Securities Act) which, in general,
provide that affiliates may not transfer our shares except pursuant to further
registration of those shares under the Securities Act or in compliance with
Rule 145 (or if applicable, Rule 144) under the Securities Act or another
available exemption from registration under the Securities Act.

APPROVAL OF THE MERGER

    Under Section 92A.120 of the Nevada Revised Statutes, the approval of the
board of directors of a company and the affirmative vote of the holders of at
least a majority of its outstanding shares on the record date for a stockholder
vote are required to approve a merger and adopt a merger agreement. WilTel's
board of directors has previously approved the merger and adopted the Merger
Agreement. If, after completion of this offer, we own less than 90% of the
outstanding shares of WilTel common stock, we would complete the acquisition of
the remaining outstanding shares of WilTel common stock through a vote of WilTel
stockholders with respect to the merger. Since we will own a majority of the
shares of WilTel common stock on the record date, we would have a sufficient
number of shares of WilTel common stock to approve the merger without the
affirmative vote of any other WilTel stockholder and, therefore, approval of the
merger by WilTel stockholders will be assured. Completion of the transaction in
this manner is referred to in this prospectus as a 'long-form merger'. Under
Section 92A.180 of the Nevada Revised Statutes, a merger can occur without a
vote of WilTel stockholders, referred to as a 'short-form merger,' if, after
completion of the offer, as it may be extended and including any subsequent
offering period, we were to own at least 90% of the outstanding shares of WilTel
common stock. If, after completion of the offer, as it may be extended and
including any subsequent offering period, we own at least 90% of the outstanding
shares of WilTel common stock, we may complete the acquisition of the remaining
outstanding shares of WilTel common stock by completing a short-form merger.

APPRAISAL (DISSENTERS') RIGHTS

    Under Nevada law, WilTel stockholders do not have dissenters' rights in
connection with the offer and would not have such rights in connection with a
long-form merger of WilTel and Merger Sub. If after successful completion of the
offer Leucadia owns at least 90% of the outstanding shares of WilTel common
stock, WilTel stockholders who (a) do not tender their shares into the offer and
hold common stock at the effective time of a short form merger, (b) who do not
wish to accept the consideration provided for in that merger and (c) comply with
the procedures provided for in Chapter 92A of the Nevada Revised Statutes (the
'NRS'), will be entitled to payment in cash of the 'fair value' of their shares
of WilTel common stock, with accrued interest, as determined through Nevada's
statutorily prescribed appraisal process. The following summarizes provisions of
Chapter 92A of the NRS regarding dissenters' rights that would be applicable in
connection with a short form merger, which will be effected as a merger of
Merger Sub with WilTel. This discussion is qualified in its entirety by
reference to Sections 92A.300 to 92A.500 of

                                       40


the NRS. A copy of Sections 92A.300 to 92A.500 of the NRS is attached to this
prospectus as Annex C. If you fail to take any action required by Nevada law,
your rights to dissent in connection with the merger will be waived or
terminated.

    Within 10 days after the effective time, WilTel will send notice of the
effective time of the merger and the availability of dissenters' rights to each
WilTel stockholder. The notice will:

        (a) state where the demand for payment must be sent and where and when
    certificates for WilTel shares are to be deposited;

        (b) supply a form for demanding payment;

        (c) set a date by which WilTel must receive the demand for payment,
    which may not be less than 30 nor more than 60 days after the date the
    notice is delivered; and

        (d) be accompanied by a copy of Sections 92A.300 through 92A.500 of the
    NRS.

    A stockholder to whom a dissenter's notice is sent must, by the date set
forth in the dissenter's notice:

        (a) demand payment;

        (b) certify whether the stockholder acquired beneficial ownership of the
    shares before the date of the first announcement to the news media or to the
    stockholders of the terms of the merger; and

        (c) deposit his or her certificates in accordance with the terms of the
    dissenter's notice.

    A beneficial stockholder of WilTel stock may assert dissenters' rights as to
shares held on the stockholder's behalf only if the stockholder submits to
WilTel the written consent of the stockholder of record to the dissent not later
than the time the beneficial stockholder asserts dissenters' rights and the
beneficial stockholder does so with respect to all shares of which he is the
beneficial stockholder or over which he has the power to direct the vote.

    WilTel stockholders who do not demand payment or deposit their certificates
where required, each by the date set forth in the dissenter's notice, will not
be entitled to demand payment for their shares under Nevada law governing
dissenters' rights.

    Within 30 days after receipt of a valid demand for payment, WilTel will pay
each dissenter who complied with the procedures described by the Nevada
dissenters' rights statute the amount WilTel estimates to be the fair value of
the shares, plus accrued interest. The payment will be accompanied by:

        (a) WilTel's balance sheet as of the end of a fiscal year ending not
    more than 16 months before the date of payment, a statement of income for
    that fiscal year, a statement of changes in shareholders' equity for that
    fiscal year and the latest available interim financial statements, if any;

        (b) a statement of WilTel's estimate of the fair value of the shares;

        (c) an explanation of how the interest was calculated;

        (d) a statement of dissenters' rights to demand payment under Section
    92A.480 of the NRS; and

        (e) a copy of Sections 92A.300 through 92A.500 of the NRS.

    WilTel may elect to withhold payment from a dissenting stockholder if such
stockholder became the beneficial owner of the shares on or after the date of
the first announcement to the news media or to the stockholders of the proposed
terms of the merger. To the extent WilTel elects to withhold payment, after
effectuating the merger, it will estimate the fair value of the shares, plus
accrued interest, and will offer to pay this amount to each dissenter who agrees
to accept it in full satisfaction of the stockholder's demand. WilTel will send
with its offer:

        (a) a statement of WilTel's estimate of the fair value of the shares;

        (b) an explanation of how the interest was calculated; and

        (c) a statement of dissenters' rights to demand payment pursuant to
    Section 92A.480 of the NRS.

    A dissenter may notify WilTel in writing of the dissenter's own estimate of
the fair value of the shares and interest due, and demand payment of his or her
estimate, less WilTel's fair value

                                       41


payment or offer for payment, or reject the offer for payment made by WilTel and
demand payment of the fair value of the dissenter's shares and interest due if
the dissenter believes that the amount paid or offered is less than the fair
value of the dissenter's shares or that the interest due is incorrectly
calculated. A dissenter waives his right to demand such payment unless the
dissenter notifies WilTel of his demand in writing within 30 days after WilTel
made or offered payment for the dissenter's shares.

    If a demand for payment remains unsettled, WilTel will commence a proceeding
within 60 days after receiving the demand for payment and petition the court to
determine the fair value of the shares of WilTel common stock and accrued
interest. If WilTel does not commence the proceeding within the 60-day period,
it will be required to pay each dissenter whose demand remains unsettled the
amount demanded.

    Each dissenter who is made a party to the proceeding is entitled to a
judgment:

        (a) for the amount, if any, by which the court finds the fair value of
    the dissenter's shares, plus interest, exceeds the amount paid by WilTel; or

        (b) for the fair value, plus accrued interest, of the dissenter's
    after-acquired shares for which WilTel elected to withhold payment pursuant
    to Nevada law.

    Under Nevada law, the fair value of shares of WilTel common stock means the
value of the shares immediately before the consummation of the merger, excluding
any increase or decrease in value in anticipation of the merger unless excluding
such increase or decrease is inequitable. The value determined by the court for
WilTel common stock could be more than, less than, or the same as the merger
consideration, but the form of consideration payable as a result of the dissent
proceeding would be cash.

    The court will determine all of the costs of the proceeding, including the
reasonable compensation and expenses of any appraisers appointed by the court.
The court will assess the costs against WilTel, except that the court may assess
costs against all or some of the dissenters, in the amounts the court finds
equitable, to the extent that the court finds the dissenters acted arbitrarily,
vexatiously or not in good faith in demanding payment. The court may also assess
the fees and expenses of the counsel and experts for the respective parties, in
amounts the court finds equitable:

        (a) against WilTel and in favor of all dissenters if the court finds
    WilTel did not substantially comply with the Nevada dissenters' rights
    statute; or

        (b) against either WilTel or a dissenter in favor of any other party, if
    the court finds that the party against whom the fees and expenses are
    assessed acted arbitrarily, vexatiously or not in good faith with respect to
    the dissenters' rights provided under the Nevada dissenter' rights statute.

    If the court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against WilTel, the court may award to
those counsel reasonable fees to be paid out of the amounts awarded to the
dissenters who were benefited.

    If a proceeding is commenced because WilTel did not pay each dissenter who
complied with the procedures described by the Nevada dissenters' rights statute
the amount WilTel estimated to be the fair value of the shares, plus accrued
interest, within 30 days after receipt of a valid demand for payment, the court
may assess costs against WilTel, except that the court may assess costs against
all or some of the dissenters who are parties to the proceeding, in amounts the
court finds equitable, to the extent the court finds that such parties did not
act in good faith in instituting the proceeding. The assessment of costs and
fees, if any, may also be affected by Nevada law governing offers of judgment.

    The foregoing summary of the rights of dissenting WilTel stockholders does
not purport to be a complete statement of such rights and the procedures to be
followed by stockholders desiring to exercise any available dissenters' rights.
The preservation and exercise of dissenters' rights require strict adherence to
the applicable provisions of Nevada law, a copy of which is attached hereto as
Annex C.

                                       42


                            DESCRIPTION OF THE CSRS

    The following is a summary description of the CSRs. WilTel stockholders are
urged to read the Merger Agreement (a copy of which is attached as Annex A to
this prospectus) in its entirety for a more complete description of the CSRs
because it is the legal document that governs the CSRs. In the event of any
discrepancy between the terms of the Merger Agreement and the following summary,
the Merger Agreement will control.

    Subject to the terms and conditions of the offer and the merger, the
consideration payable by Leucadia per share of WilTel common stock in the offer
and merger will include one CSR. As described in greater detail below, the
purpose of the CSRs is to give WilTel stockholders who participate in the offer
and merger the opportunity to receive additional Leucadia common shares in
connection with any Sale of WilTel (as defined below) consummated after the
merger and on or before the Maturity Date (as defined below) in which Leucadia
or its subsidiaries receive Net Proceeds (as defined below) in excess of the
Deal Price (as defined below). You should not take the existence of the CSRs as
an indication that a Sale of WilTel will occur or, if one does occur, as to the
proceeds therefrom. Leucadia will conduct its business (including all decisions
relating to whether, when, how and for what consideration to dispose of any
assets) as it in its sole discretion determines. Leucadia presently has no
intention to dispose of or to entertain offers to sell its shares of WilTel
common stock or all or substantially all of WilTel's assets.

    The CSRs will be non-assignable and non-transferable by any holder thereof,
except as required by any applicable community property laws or laws of descent
and distribution. CSRs will not be represented by any certificate. A CSR will
not entitle its holder to any of the rights of a shareholder in Leucadia
(including voting or dividend rights).

    The CSRs will become effective at the time of the merger and will mature at
11:59 p.m. New York City time on the earlier of (i) the date, if any, on which a
Sale of WilTel for Net Proceeds in excess of the Deal Price is consummated and
(ii) October 15, 2004, provided that if after the merger and prior to August 21,
2004 Leucadia or WilTel enter into a definitive agreement with an unaffiliated
third party providing for a Sale of WilTel, the date in this clause (ii) will be
the later of (A) October 15, 2004 and (B) the earlier of (x) the date the Sale
of WilTel pursuant to such agreement is consummated and (y) the date such Sale
of WilTel is abandoned (the earlier of (i) and (ii) being the 'Maturity Date').

    For purposes of the CSRs, 'Sale of WilTel' means the occurrence of any of
the following events: (i) a sale by WilTel of all or substantially all of the
assets of WilTel and its subsidiaries to another entity (other than Leucadia or
one or more of its subsidiaries ('Permitted Holders')); (ii) any 'person' or
'group', other than Permitted Holders, is or becomes the 'beneficial owner',
directly or indirectly, of more than 50% of the issued and outstanding shares of
capital stock of WilTel having general voting power under ordinary circumstances
('Voting Stock'); or (iii) WilTel consolidates with, or merges with or into,
another entity (other than a Permitted Holder), other than any such transaction
where (A) the outstanding Voting Stock of WilTel is converted into or exchanged
for voting securities of the surviving entity and (B) immediately after such
transaction Permitted Holders are the 'beneficial owners', directly or
indirectly, of more than 50% of the total voting power of the surviving entity.
For purposes of this definition, the term 'beneficial owner' is used as defined
in Rules 13d-3 and 13d-5 under the Exchange Act and the terms 'person' or
'group' are used as such terms are used in Section 13(d) and 14(d) of the
Exchange Act. For the avoidance of doubt, only the consummation of the
transactions described above in this definition will constitute a 'Sale of
WilTel' and neither any discussions, negotiations or preparations, nor entering
into any agreement, relating to any such transaction will be deemed a 'Sale of
WilTel'.

    If there is consummated after the merger and on or before the Maturity Date
a Sale of WilTel for Net Proceeds in excess of the Deal Price, then, following
the Maturity Date, Leucadia will issue for each CSR that number of whole
Leucadia common shares (after aggregating all

                                       43


CSRs held by the holder thereof) determined under the following formula
(calculated to the fourth decimal point) and the following paragraphs:


                         
             Sale Profit
             -----------    divided by Parent Price
             50,000,000


          provided, however, that in no event shall more than a total of the Cap
          Number (as defined below) of Leucadia common shares be issuable in
          respect of all CSRs in the aggregate, and the number of Leucadia
          common shares issuable to each CSR holder will be reduced pro rata to
          the extent necessary to give effect to this limitation

          where,

    'Sale Profit' means the amount of Net Proceeds in excess of the Deal Price;

    'Net Proceeds' means the U.S. dollar amount (expressed as a whole number) of
aggregate proceeds (with any non-cash proceeds to be valued at their fair market
value as determined in good faith by Leucadia's board of directors) received by
Leucadia, WilTel or any of their subsidiaries in respect of a Sale of WilTel
consummated after the merger and on or before the Maturity Date, plus the fair
market value (to be determined in good faith by Leucadia's board of directors)
of any assets of WilTel or its subsidiaries retained by Leucadia upon
consummation of such Sale of WilTel, net of (i) the costs relating to such
transaction (including regulatory filing fees, legal, accounting and investment
banking fees, and brokerage and sales commissions), (ii) taxes paid or payable
as a result of such transaction, (iii) amounts required to be applied to the
repayment of principal, premium (if any) and interest on any indebtedness
required to be paid as a result of such transaction, (iv) deduction of
appropriate amounts to be provided as a reserve in accordance with U.S.
generally accepted accounting principles against any liabilities associated with
such transaction (including, without limitation, pension and other
post-employment benefit liabilities and liabilities related to environmental
matters or against any indemnification obligations associated with such
transaction) and (v) all liabilities of WilTel or its subsidiaries that are
retained by Leucadia or any of its subsidiaries following consummation of such
transaction;

    'Deal Price' equals (A) 800,000,000, plus (B) the aggregate U.S. dollar
amount (expressed as a whole number) of contributions to capital and other
investments made by Leucadia or any of its affiliates (other than WilTel and its
subsidiaries) in, and expenditures funded by Leucadia or any of its affiliates
(other than WilTel and its subsidiaries) in support of, WilTel or its
subsidiaries after the merger and prior to the Maturity Date, minus (C) the
aggregate U.S. dollar amount (expressed as a whole number) of dividends paid by
WilTel to Leucadia after the merger and prior to the Maturity Date, plus (D) an
amount equal to notional interest on the excess, if any, of (i) the amounts
described in clause (B) above over (ii) the amount described in clause (C)
above, at a rate per annum of 8%, determined based on the number of days elapsed
from the closing date of the merger to the Maturity Date;

    'Parent Price' equals 37.72, reduced to reflect the amount (if any) of cash
dividends per Leucadia common share paid (or with a record date) between August
21, 2003 and the Maturity Date in excess of Leucadia's regular $0.25 per share
annual dividend; and

    'Cap Number' means the lesser of (A) 11,000,000 and (B) the number of
Leucadia common shares issued by Leucadia in the offer and the merger (excluding
consideration paid to any WilTel stockholders who properly exercised appraisal
(dissenters') rights) minus one.

    If, on the Maturity Date, Net Proceeds are equal to or less than the Deal
Price, the CSRs will automatically terminate and no consideration shall be
deliverable in respect thereof. If, on the Maturity Date, the amount determined
pursuant to the above formula is greater than zero, Leucadia will thereafter
issue to each CSR holder the number of whole Leucadia common shares to which
such holder is entitled as herein described (rounded down to the nearest whole
share, after aggregating all CSRs held by such holder), and the CSRs will be
automatically cancelled.

    If between the date of the merger and the Maturity Date the outstanding
Leucadia common shares are changed into a different number of shares or a
different class, by reason of the occurrence or record date of any stock
dividend, subdivision, reclassification, recapitalization, split,

                                       44


combination, exchange of shares or similar transaction, then the number of and
kind of shares issuable in respect of the CSRs will be appropriately adjusted.
No dividends or other distributions with respect to Leucadia common shares with
a record date before the Maturity Date will be paid in respect of, and no
interest will be paid or will accrue on, any Leucadia common shares issuable in
respect of CSRs.

    If Leucadia common shares become issuable under the CSRs, Leucadia will
determine the amount required under applicable tax laws to be treated as
interest income, and may, at its option, issue two stock certificates to each
holder of CSRs, one certificate in respect of the shares treated as interest and
the other certificate in respect of the remaining shares; provided, however,
that in no event will Leucadia issue any fractional share interests.

    All computations and determinations relating to the CSRs will be made by
Leucadia in good faith. Promptly after the Maturity Date, Leucadia will notify
holders of CSRs in writing (which notification may be made through a press
release which will be attached to a submission that is made publicly available
on the SEC's EDGAR system) of Leucadia's determination as to (i) whether a Sale
of WilTel occurred, (ii) the amount of any Net Proceeds received in respect
thereof, (iii) the amount (if any) of any resulting Sale Profit, and (iv) the
number of Leucadia common shares (if any) due and payable to CSR holders.

                 CERTAIN LEGAL MATTERS AND REGULATORY APPROVALS

REGULATORY APPROVALS

    Antitrust. The offer and the merger are subject to the HSR Act, which
provides that certain acquisition transactions may not be consummated unless
certain information has been furnished to the Antitrust Division of the
Department of Justice (the 'Antitrust Division') and the Federal Trade
Commission (the 'FTC') and certain waiting period requirements have been
satisfied.

    Leucadia and WilTel filed their Notification and Report Forms with respect
to the offer under the HSR Act on August 29, 2003. Leucadia has been notified
that early termination of the waiting period under the HSR Act has been granted.

    The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of transactions such as Leucadia's acquisition of shares of
WilTel common stock pursuant to the offer and the merger. At any time before or
after Leucadia's acquisition of shares of WilTel common stock, the Antitrust
Division or the FTC could take such action under the antitrust laws as it deems
necessary or desirable in the public interest, including seeking to enjoin the
acquisition of shares pursuant to the offer or otherwise seeking divestiture of
shares of WilTel common stock acquired by Leucadia or divestiture of substantial
assets of Leucadia or its subsidiaries. Private parties, as well as state
governments, may also bring legal action under the antitrust laws under certain
circumstances. There can be no assurance that a challenge to the offer or other
acquisition of shares of WilTel common stock by Leucadia on antitrust grounds
will not be made or, if such a challenge is made, of the result. See 'The
Offer -- Conditions of the Offer'.

    Other Regulatory Approvals. WilTel holds certain licenses, authorizations
and certificates issued by the Federal Communications Commission ('FCC') and
State utility commissions. Prior to acquiring the beneficial and voting rights
to 50% or more of WilTel's outstanding voting stock, Leucadia will need to
obtain the approval of the FCC and certain state utility commissions. In order
to obtain such approvals, Leucadia filed applications with the FCC on September
3, 2003 and will file notifications and applications with certain state utility
commissions. Although it is not possible to predict the timing of regulatory
agencies, Leucadia believes that if no challenges are filed to these
applications, Leucadia should obtain the requisite FCC and state commission
approvals within 60 to 120 days. There can be no assurance that a challenge to
the offer or the merger will not be made or, if such a challenge is made, of the
result. See 'The Offer -- Conditions of the Offer'.

                                       45


NON-U.S. APPROVALS

    We are unaware of any requirement for the filing of information with, or the
obtaining of the approval of, governmental authorities in any non-U.S.
jurisdiction that is applicable to the offer or the merger.

STATE TAKEOVER LAWS

    A number of states have adopted takeover laws and regulations which purport,
to varying degrees, to be applicable to attempts to acquire securities of
corporations which have substantial assets, stockholders, principal executive
offices or principal places of business in those states. We have not attempted
to comply with any state takeover statutes in connection with the offer, since
we do not believe that any of these apply. However, we reserve the right to
challenge the validity or applicability of any state law allegedly applicable to
the offer, and nothing in this prospectus nor any action taken in connection
herewith is intended as a waiver of that right. If one or more takeover statutes
apply to the offer and are not found to be invalid, we may be required to file
documents with, or receive approvals from, relevant state authorities and we may
also be unable to accept for exchange shares of WilTel common stock tendered
into the offer or may delay the offer. See 'The Offer -- Conditions of the
Offer'.

STOCKHOLDER LITIGATION

    Individual WilTel stockholders have filed complaints in the District Court
of Tulsa County, Oklahoma, the District Court of Clark County, Nevada, the
District Court of Washoe County, Nevada, and the Supreme Court of the State of
New York, New York County, purporting to commence class action lawsuits against
Leucadia, WilTel, and directors of WilTel. The complaints are (1) Sleeper v.
WilTel Communications Group, Inc., et al. (Civil Action No. CJ 2003 03163,
District Court Tulsa Co. Oklahoma); (2) Merullo v. WilTel Communications Group,
Inc., et al. (Civil Action No. A467774, District Court Clark Co. Nevada);
(3) Gottdiener v. WilTel Communications Group, Inc., et al. (Civil Action No.
A467700, District Court Clark Co. Nevada); (4) Guy v. WilTel Communications
Group, Inc., et al. (Civil Action No. A467773, District Court Clark Co. Nevada);
(5) Guerra v. WilTel Communications Group, Inc., et al. (Civil Action No.
A467738, District Court Clark Co. Nevada); (6) Hersch v. WilTel Communications
Group, Inc., et al. (Civil Action No. CV03-03220, District Court Washoe Co.
Nevada, transferred to Clark Co. Nevada); (7) Provorny v. Leucadia National
Corporation, et al. (Case No. 03-109061, N.Y. Supreme Court, County of New
York); and (8) Guy v. WilTel Communications Group, Inc., et al. (Civil Action
No. 03-115368, N.Y. Supreme Court, County of New York). In general, the
complaints allege, among other things: (a) breaches of fiduciary duty by
Leucadia, WilTel, and the members of WilTel's board of directors in connection
with the offer and merger, including, among other things, allegations of
inadequate disclosure; (b) that the consideration Leucadia is offering WilTel
stockholders is inadequate; and (c) that Leucadia is acting to further its own
interests at the expense of WilTel stockholders.

    Among other remedies, the complaints seek to enjoin completion of the offer
and merger or, alternatively, damages in an unspecified amount and attorneys'
fees and rescission in the event that proposed transaction occurs. Leucadia
believes the complaints to be without merit. We will make publicly available, to
the extent required by applicable law, any material updates to the information
disclosed regarding these complaints.

    On October 15, 2003, subject to approval from directors and officers
insurance carriers, the parties in these litigations reached an agreement in
principle to settle the litigation based upon increased disclosure in this
prospectus and the WilTel Recommendation Statement. The proposed settlement is
subject to numerous conditions, including the consummation of the offer and
merger, the drafting and execution of a formal settlement agreement, and final
approval of the settlement by the New York courts. Plaintiffs' counsel intend to
apply to the New York courts for an award of attorneys' fees and reimbursement
of expenses in an amount not yet agreed upon by the parties.

                                       46


    If any of the conditions to the proposed settlement do not occur, the
litigation could proceed and plaintiffs could seek the relief sought in their
complaints.

                          CERTAIN EFFECTS OF THE OFFER

EFFECTS ON THE MARKET; EXCHANGE ACT REGISTRATION

    The tender and the acceptance of shares of WilTel common stock in the offer
will reduce the number of shares of WilTel common stock that might otherwise
trade publicly and also the number of holders of shares of WilTel common stock.
This could adversely affect the liquidity and market value of the remaining
shares of WilTel common stock held by the public. Depending upon the number of
shares of WilTel common stock tendered to and accepted by us in the offer, the
shares of WilTel common stock may no longer meet the requirements of the
National Association of Securities Dealers for continued inclusion on NASDAQ.

    If NASDAQ ceased publishing quotations for the shares of WilTel common
stock, it is possible that the shares of WilTel common stock would continue to
trade in the over-the-counter market and that price or other quotations would be
reported by other sources. The extent of the public market for such shares of
WilTel common stock and the availability of such quotations would depend,
however, upon such factors as the number of stockholders and/or the aggregate
market value of such securities remaining at such time, the interest in
maintaining a market in the shares of WilTel common stock on the part of
securities firms, the possible termination of registration under the Exchange
Act as described below, and other factors. We cannot predict whether the
reduction in the number of shares of WilTel common stock that might otherwise
trade publicly would have an adverse or beneficial effect on the market price
for, or marketability of, the shares of WilTel common stock.

    Shares of WilTel common stock are currently registered under the Exchange
Act. WilTel can terminate that registration upon application to the SEC if the
outstanding shares of WilTel common stock are not listed on a national
securities exchange and if there are fewer than 300 holders of record of shares
of WilTel common stock. Termination of registration of the shares of WilTel
common stock under the Exchange Act would reduce the information that WilTel
must furnish to its stockholders and to the SEC and would make certain
provisions of the Exchange Act, such as the short-swing profit recovery
provisions of Section 16(b) and the requirement of furnishing a proxy statement
in connection with stockholders meetings pursuant to Section 14(a) and the
related requirement of furnishing an annual report to stockholders, no longer
applicable with respect to the shares of WilTel common stock. In addition, if
the shares of WilTel common stock are no longer registered under the Exchange
Act, the requirements of Rule 13e-3 under the Exchange Act with respect to
'going-private' transactions would no longer be applicable to WilTel.
Furthermore, the ability of 'affiliates' of WilTel and persons holding
'restricted securities' of WilTel to dispose of such securities pursuant to Rule
144 under the Securities Act may be impaired or eliminated. If registration of
the shares of WilTel common stock under the Exchange Act were terminated, they
would no longer be eligible for NASDAQ listing or for continued inclusion on the
Federal Reserve Board's list of 'margin securities.'

    Leucadia may seek to cause WilTel to apply for termination of registration
of the shares of WilTel common stock under the Exchange Act as soon after the
expiration of the offer as the requirements for such termination are met. If the
NASDAQ National Market listing and the Exchange Act registration of the shares
of WilTel common stock are not terminated prior to the merger, then the shares
of WilTel common stock will be delisted from the NASDAQ National Market and the
registration of the shares of WilTel common stock under the Exchange Act will be
terminated following the consummation of the merger.

    The shares of WilTel common stock are presently 'margin securities' under
the regulations of the Federal Reserve Board, which has the effect, among other
things, of allowing brokers to extend credit on the collateral of shares of
WilTel common stock. Depending on the factors similar to those described above
with respect to listing and market quotations, following consummation of the
offer, the shares of WilTel common stock may no longer constitute 'margin
securities' for the

                                       47


purposes of the Federal Reserve Board's margin regulations, in which event the
shares of WilTel common stock would be ineligible as collateral for margin loans
made by brokers.

FINANCING OF THE OFFER

    Our offer is not conditioned on the receipt of financing. Leucadia's fees
and expenses in connection with the offer will be paid from Leucadia's available
capital resources. Leucadia intends to deliver the Leucadia common shares
offered in the offer and the merger from Leucadia's available treasury shares.

CONDUCT OF WILTEL IF THE OFFER IS NOT COMPLETED

    If the offer is not completed because the minimum condition or another
condition is not satisfied or, if permissible, waived, we expect that WilTel
will continue to be significantly owned by Leucadia and operate its business as
presently operated, subject to market and industry conditions and the terms of
the agreements and other documents referred to below under ' -- Relationships
With WilTel'. We presently have no intention to dispose of or to entertain
offers to sell our shares of WilTel common stock.

PLANS AND PROPOSALS FOR WILTEL FOLLOWING COMPLETION OF THE MERGER

    Consummation of the merger will permit us to receive the benefits that
result from ownership of all of the equity interest in WilTel. Such benefits
include management and investment discretion with regard to the future conduct
of WilTel's business, the benefits of the profits generated by operations and
increases, if any, in WilTel's value and the ability to utilize, subject to
applicable limitations, WilTel's current and future tax losses. Conversely, we
will bear the risk of any decrease in WilTel's value and losses generated by
operations. If you become a Leucadia shareholder as a result of the offer or
merger, your investment should indirectly benefit from any of the foregoing as
well as other benefits Leucadia may obtain as a result of the transactions, and,
conversely, be indirectly exposed to the foregoing risks.

    Except as otherwise described in this prospectus, we have no current plans
or proposals or negotiations which relate to or would result in: (i) an
extraordinary corporate transaction, such as a merger, reorganization or
liquidation involving WilTel; (ii) any purchase, sale or transfer of a material
amount of assets of WilTel; (iii) any change in the management of WilTel or any
change in any material term of the employment contract of any executive officer;
or (iv) any other material change in WilTel's corporate structure or business.
However, in light of the consolidation and other changes taking place in the
telecommunications industry, we continually are evaluating and considering
possible acquisition and disposition transactions which may involve Leucadia or
WilTel.

RELATIONSHIPS WITH WILTEL

    In considering whether to tender your shares in the offer, you should be
aware of various existing agreements and ongoing and prior relationships,
arrangements and transactions between Leucadia and WilTel, as described under
'Interests of Certain Persons in the Offer And Subsequent Merger'. Also, please
see 'Comparison of Rights of Holders of WilTel Common Stock and Leucadia Common
Shares -- Shareholder Approval of Business Combinations -- WilTel'.

ACCOUNTING TREATMENT

    Our acquisition of WilTel common stock pursuant to the offer will be
accounted for under the purchase method of accounting in accordance with
accounting principles generally accepted in the United States. In addition, as a
result of acquiring the additional shares of WilTel common stock, we will
consolidate the financial position and results of operations of WilTel from the
date of this additional acquisition and no longer account for our investment in
WilTel under the equity method of accounting.

        INTERESTS OF CERTAIN PERSONS IN THE OFFER AND SUBSEQUENT MERGER

INTERESTS OF MANAGEMENT AND THE WILTEL BOARD

    One of WilTel's officers and some members of the WilTel board of directors
have interests in the proposed transactions that may be different from, or in
addition to, the interests of WilTel stockholders generally.

    Two of the nine members of WilTel's board of directors (Ian M. Cumming and
Joseph S. Steinberg) are the Chairman and President, respectively, directors and
principal shareholders of Leucadia. In addition, Leucadia has designated two
other members to WilTel's board of directors (Alan J. Hirschfield and
Jeffrey C. Keil).

    Leucadia beneficially owns 23,700,000 shares of WilTel common stock,
representing 47.4% of the outstanding shares of WilTel common stock. To the best
of our knowledge, as of August 21, 2003, none of the directors, executive
officers and affiliates of Leucadia own any shares of WilTel common stock.
Although neither Mr. Cumming nor Mr. Steinberg directly owns any shares of
WilTel common stock, by virtue of their ownership of approximately 15.7% and
15.4% interests, respectively, in Leucadia (as of June 30, 2003), each may be
deemed to be the indirect beneficial owner of shares of WilTel common stock
beneficially owned by Leucadia. Mr. Cumming and Mr. Steinberg have an oral
agreement pursuant to which they will consult with each other as to the election
of a mutually acceptable board of directors of Leucadia. Neither Leucadia nor,
to the best of its knowledge, any of the directors, executive officers or
affiliates of Leucadia have bought or sold any shares of WilTel common stock
within the past sixty days.

    The Merger Agreement provides that from and after the merger, Leucadia and
WilTel will indemnify the individuals who at or prior to the merger were
directors or officers of WilTel with respect to all acts or omissions by them in
their capacities as such at any time prior to the merger, to the fullest extent
required by WilTel's articles of incorporation and by-laws (as in effect on
August 21, 2003) and permitted under applicable law. In addition, the Merger
Agreement provides that for a three year period commencing immediately after the
merger, Leucadia and WilTel will maintain in effect directors' and officers'
liability insurance covering acts or omissions occurring prior to the merger
with respect to those persons who are currently covered by WilTel's current

                                       49


primary directors' and officers' liability insurance policy, on terms with
respect to such coverage not less favorable to WilTel's directors and officers
currently covered by such insurance than those of such policy in effect on
August 21, 2003 (or Leucadia or WilTel may substitute therefor insurance
policies, issued by reputable carriers, with respect to matters occurring prior
to the merger); provided, however, that the aggregate amount of coverage under
such insurance will be limited to $10 million. For those amounts of directors'
and officers' liability insurance in excess of the insurance described in the
preceding sentence which are currently provided under WilTel's other current
directors' and officers' liability insurance policies (the 'Other Policies'),
the Merger Agreement provides that for a six year period commencing immediately
after the merger, Leucadia will make payments to those persons who are currently
covered by such Other Policies to the extent such payments otherwise would have
been made under such Other Policies (as in effect on August 21, 2003) had such
Other Policies remained in effect for a period of six years following the
merger, with respect to acts or omissions occurring prior to the merger;
provided, however, that the maximum amount of payments that Leucadia and WilTel
agreed to make will not exceed $50 million in the aggregate.

    H. E. Scruggs, Senior Vice President -- Corporate of WilTel, is a Vice
President of Leucadia and does not receive compensation from WilTel.

    In addition, each member of the Special Committee is entitled to $40,000 in
director fees and the chairman of the Special Committee is entitled to $50,000.
These fees will be paid by WilTel.

CERTAIN AGREEMENTS BETWEEN LEUCADIA AND WILTEL

    In connection with the plan of reorganization of WilTel's predecessor
company (the 'Plan'), Leucadia and WilTel entered into a Stockholders Agreement
as of October 15, 2002. The Stockholders Agreement contains various provisions
that were presumably intended by the directors of WilTel's predecessor company
to benefit the holders of WilTel stock other than Leucadia (the 'Publicly Held
Stock'). Specifically, pursuant to the Stockholders Agreement, Leucadia and
WilTel agreed, among other things, to the following provisions, any and all of
which may be amended with either (i) the prior approval of the holders of a
majority of the Publicly Held Stock ('Stockholder Approval') or (ii) the prior
consent of a majority of the Independent Company Directors (as defined in the
Stockholders Agreement) of WilTel ('Board Approval'):

    'STANDSTILL' PROVISIONS

    The material 'standstill' provisions of the Stockholders Agreement provide
that, until October 16, 2007:

     Leucadia would not (i) commence any tender or exchange offer for WilTel
     voting securities other than a Permitted Investor Tender Offer (as defined
     below) commenced after October 15, 2004 or (ii) acquire more than 49% of
     the outstanding voting securities of WilTel except pursuant to a Permitted
     Investor Tender Offer commenced after October 15, 2004.

     Prior Stockholder Approval or Board Approval would be required for (i) the
     termination (other than in accordance with its terms) or amendment of the
     Stockholders Agreement and (ii) any transaction between or involving
     WilTel, on the one hand, and Leucadia, on the other hand, other than a
     Permitted Investor Tender Offer after October 15, 2004.

     Prior Board Approval would be required for any change to the provisions of
     WilTel's bylaws relating to the nomination of directors of WilTel, or the
     imposition or deletion of any super-majority requirement or stockholder
     approval requirement for the amendment of WilTel's articles of
     incorporation or bylaws.

    Leucadia also agreed that, until October 16, 2005, Leucadia would not cause
a merger with WilTel following a Permitted Investor Tender Offer unless the per
share merger consideration offered to WilTel stockholders was at least the same
as paid in the Permitted Investor Tender Offer.

    Leucadia further agreed that, until October 16, 2007, Leucadia would only
tender its WilTel shares into, or give a proxy to vote or otherwise agree to
vote its WilTel shares for or otherwise support, a Third Party Sale Transaction
(as defined below), if Leucadia first required the third

                                       50


party seeking to engage in a Third Party Sale Transaction to agree that (i) the
same form (and a proportionate amount) of consideration would be paid to all
other holders of WilTel shares as to Leucadia in the Third Party Sale
Transaction, (ii) all other holders of WilTel shares would be given the same
opportunity to participate in the Third Party Sale Transaction, and (iii) the
Third Party Sale Transaction would be structured so as to seek the acquisition
or approval of a majority of the WilTel shares not already owned by Leucadia.
The foregoing restrictions do not apply to a Third Party Sale Transaction that
is structured as a tender or exchange offer that would result in the third party
acquiring beneficial ownership of no more than 49% of the WilTel shares so long
as the acquiror in such tender or exchange offer agreed to be bound by the terms
of the Stockholders Agreement.

    The Stockholders Agreement defines 'Third Party Sale Transaction' to mean
any of the following that has not been approved or recommended by a majority of
the members of WilTel's board of directors: (A) any tender or exchange offer for
WilTel voting securities made by a person other than (x) WilTel or one of its
wholly owned subsidiaries or (y) directly or indirectly, Leucadia, or (B) any
merger, consolidation, business combination, sale of all or substantially all of
the assets of WilTel and its subsidiaries, dissolution, liquidation,
restructuring, recapitalization or similar transaction of or involving WilTel.

    Each of the Stockholders Agreement provisions described above will terminate
upon consummation of the offer, and the remaining provisions of the Stockholders
Agreement will terminate upon consummation of the merger.

    A 'Permitted Investor Tender Offer' is defined in the Stockholders Agreement
as a tender or exchange offer made by or on behalf of Leucadia for WilTel voting
securities that:

     is subject to a non-waivable condition that the holders of at least a
     majority of the WilTel voting securities not owned by Leucadia have
     tendered and not withdrawn their voting securities;

     is open to all holders of WilTel voting securities; and

     seeks to purchase at least a majority of the WilTel voting securities that
     are not owned by Leucadia.

    Leucadia has received Board Approval for the commencement of the offer, the
merger and the other transactions contemplated by the Merger Agreement.

    BOARD PROVISIONS

    The Stockholders Agreement also provides that:

     Until October 16, 2007, Leucadia must use its best efforts to cause
     WilTel's board of directors to be comprised of nine directors, including
     six Independent Company Directors.

     Until October 16, 2004, Leucadia must vote all WilTel voting securities
     that it owns for the election of the directors who were initially
     designated by the creditors committee of WilTel's predecessor company or
     their permitted successors.

     Leucadia is entitled to designate (i) four members of WilTel's board of
     directors for as long as Leucadia owns at least 20% of the WilTel common
     stock and (ii) at least one member of WilTel's board of directors for as
     long as Leucadia owns at least 10% of the WilTel common stock.

    In addition to the Stockholders Agreement, Leucadia is a party to the
following agreements with WilTel:

     A Stockholder Rights and Co-Sale Agreement entered into pursuant to the
     Plan under which, among other things, certain WilTel stockholders are
     eligible to participate in proposed issuances or actual issuances of Rights
     Securities (as defined in the agreement) to Leucadia until October 15,
     2007. In addition, under this agreement certain WilTel stockholders would
     be eligible to participate in any transfer (other than Exempt Transactions
     (as defined in the agreement) and transfers to affiliates of Leucadia) by
     Leucadia of 33% or more of the shares of WilTel common stock outstanding
     until October 15, 2007. The Merger Agreement

                                       51


     provides that the Stockholder Rights and Co-Sale Agreement will terminate
     upon consummation of the merger.

     A registration rights agreement entered into pursuant to the Plan under
     which WilTel has granted Leucadia certain rights to obligate WilTel to
     register for sale under the Securities Act shares of WilTel common stock
     owned by Leucadia or its affiliates. This agreement also provides customary
     indemnification from WilTel for the benefit of Leucadia.

     A one-year Restructuring Services Agreement effective as of October 16,
     2002 under which Leucadia provides advice to WilTel with respect to
     management, operations, future business opportunities, and other matters to
     be mutually determined between WilTel and Leucadia. Leucadia does not
     receive any compensation for services rendered under this agreement, but is
     reimbursed for all expenses incurred in connection with its performance
     under the agreement. This agreement is terminable upon 90 days notice by
     either Leucadia or WilTel.

                                       52


                              THE MERGER AGREEMENT

    The following is a summary of the Merger Agreement. This summary does not
purport to be a complete description of the terms and conditions of the Merger
Agreement and is qualified in its entirety by reference to the Merger Agreement,
a copy of which is attached as Annex A to this prospectus. WilTel stockholders
are urged to read the Merger Agreement in its entirety. In the event of any
discrepancy between the terms of the Merger Agreement and the following summary,
the Merger Agreement will control.

THE OFFER

    The Merger Agreement provides for the making of the offer. The obligation of
Leucadia to accept for purchase and to exchange Leucadia common shares and CSRs
for shares of WilTel common stock tendered pursuant to the offer is subject to
the satisfaction of the minimum condition and certain other conditions described
under 'The Offer -- Conditions of the Offer'.

    We may (A) extend the offer beyond the scheduled expiration date set forth
on the cover of this prospectus, or any subsequent scheduled expiration date,
if, at the scheduled expiration of the offer, any of the conditions to our
obligation to accept for exchange, and to exchange, Leucadia common shares and
CSRs for shares of WilTel common stock tendered shall not be satisfied or, to
the extent permitted by the Merger Agreement, waived, subject, however, to the
right of Leucadia or WilTel to terminate the Merger Agreement as described below
under ' -- Termination of the Merger Agreement,' and (B) extend the offer for
any period required by any rule, regulation or interpretation of the SEC
applicable to the offer. Each extension may last for no more than ten business
days, unless WilTel and Leucadia agree in writing to allow for a longer period.

    We may elect to provide a subsequent offering period of up to 20 business
days after the acceptance of shares of WilTel common stock in the offer if,
(i) on the expiration date of the offer, all of the conditions to the offer have
been satisfied or waived, but the total number of shares of WilTel common stock
that have been validly tendered and not withdrawn pursuant to the offer plus the
number of shares of WilTel common stock owned by us as of the scheduled
expiration date is less than 90% of the total number of shares of WilTel common
stock then outstanding, and (ii) the requirements of Rule 14d-11 under the
Exchange Act have been met.

    PROMPT PAYMENT FOR SHARES OF WILTEL CAPITAL STOCK IN THE OFFER

    Subject to the terms of the offer and the Merger Agreement, and the
satisfaction, or waiver to the extent permitted, of the conditions to the offer,
we are required to accept for exchange all shares of WilTel common stock validly
tendered and not withdrawn pursuant to the offer promptly after the applicable
expiration date of the offer, as it may be extended pursuant to the Merger
Agreement, and are required to exchange all accepted shares of WilTel common
stock promptly after acceptance. We will not issue fractional Leucadia common
shares in the offer. Instead, each tendering WilTel stockholder who would
otherwise be entitled to a fractional share (after aggregating all fractional
Leucadia common shares that otherwise would be received by the stockholder) will
receive cash (without interest and subject to any withholding for taxes) equal
to such stockholder's proportionate interest in the net proceeds from the sale
in the open market by the exchange agent and depository of the aggregated
fractional shares of Leucadia issued for such purposes.

THE MERGER

    GENERALLY

    The Merger Agreement provides that after completion of the offer, Merger Sub
will, subject to the conditions described below, be merged into WilTel. Upon
completion of the merger, WilTel will continue as the 'surviving corporation'
and will be a subsidiary of Leucadia.

                                       53


    THE COMPLETION OF THE MERGER

    The merger will become effective when the certificate of merger is filed
with the Secretary of State of the State of Nevada or at such other time as
specified in the certificate of merger. The merger will be completed after all
of the conditions to the merger contained in the Merger Agreement are satisfied
or, where permissible, waived. Upon completion of the merger:

     the directors of Merger Sub and the officers of WilTel immediately before
     the merger will become the directors and officers, respectively, of the
     surviving corporation;

     the articles of incorporation of the surviving corporation will be
     substantively identical to WilTel's articles of incorporation immediately
     before the merger, until they are subsequently amended as provided by
     applicable law and such articles of incorporation;

     the bylaws of the surviving corporation will be substantively identical to
     Merger Sub's bylaws immediately before the merger, until they are
     subsequently amended as provided by applicable law and such bylaws; and

     the Stockholders Agreement and the Stockholders Rights and Co-Sale
     Agreement will terminate and be of no further force or effect.

    MANNER AND BASIS OF CONVERTING SHARES OF WILTEL COMMON STOCK IN THE MERGER

    Under the terms of the Merger Agreement, upon completion of the merger, each
share of WilTel common stock outstanding immediately before the merger other
than Dissenting Shares (as defined in the Merger Agreement) or shares of WilTel
common stock held by WilTel, Leucadia or any subsidiary of Leucadia, will be
converted into the right to receive (i) 0.4242 of a Leucadia common share and
(ii) one CSR. Shares of WilTel common stock held by WilTel, Leucadia or any
subsidiary of Leucadia immediately before the completion of the merger will be
canceled at the effective time of the merger without payment of any
consideration.

    We will not issue fractional Leucadia common shares in the merger. Instead,
each stockholder who would otherwise be entitled to a fractional share (after
aggregating all fractional Leucadia common shares that otherwise would be
received by the stockholder) will receive cash (without interest and subject to
any withholding for taxes) equal to such stockholder's proportionate interest in
the net proceeds from the sale in the open market by the exchange agent and
depository of the aggregated fractional common shares of Leucadia issued for
such purposes.

    The Merger Agreement provides that promptly after the date of completion of
the merger, the exchange agent and depository will mail to each record holder of
a certificate or certificates that represented shares of WilTel common stock
immediately before the merger, a letter of transmittal and instructions for use
in exchanging WilTel common stock certificates for Leucadia common share
certificates. In addition, the Merger Agreement contemplates that, promptly
after the exchange agent and depository receives back from a record holder a
WilTel common stock certificate, the letter of transmittal and any other
documents that are reasonably required by the exchange agent and depository or
Leucadia, the exchange agent and depository will mail to the record holder a
certificate or certificates representing the appropriate number of Leucadia
common shares, any dividends or other distributions to which the holder is
entitled pursuant to the Merger Agreement and an amount of cash for any
fractional share. The CSRs will not be evidenced by any form of certificate.

    After the completion of the merger, each certificate that previously
represented shares of WilTel common stock will be cancelled and retired. Each
holder of a certificate of WilTel common stock shall cease to have any rights
with respect thereto, except the right to receive Leucadia common shares, CSRs,
any dividends or other distributions to which the holder is entitled pursuant to
the Merger Agreement and cash for any fractional share. We will not pay
dividends or other distributions on any Leucadia common shares to be issued in
exchange for any WilTel common stock certificate that is not surrendered until
the WilTel common stock certificate is properly surrendered, as provided in the
Merger Agreement.

                                       54


    BASIS OF CONVERTING SHARES OF COMMON STOCK OF MERGER SUB IN THE MERGER

    Under the terms of the Merger Agreement, upon completion of the merger, each
share of common stock of Merger Sub outstanding immediately before the merger
will be converted into one share of common stock of the surviving corporation.

REPRESENTATIONS AND WARRANTIES

    In the Merger Agreement, WilTel has provided customary representations and
warranties concerning, among other things, its capitalization and financial
condition, the accuracy and completeness of its filings with the SEC, certain
tax matters, and authorizations, consents and approvals needed for the
transactions. We have made similar customary representations, including those
concerning the accuracy and completeness of our filings with the SEC and
consents and approvals needed for the transactions. In general, the
representations and warranties of each party will expire upon completion of the
merger.

CONDUCT OF WILTEL'S BUSINESS PRIOR TO COMPLETION OF THE MERGER

    The Merger Agreement contemplates that, until the completion of the merger,
WilTel will conduct its business in the ordinary course consistent with past
practice and will use commercially reasonable efforts to preserve the goodwill
of those having business relationships with it and comply in all material
respects with applicable laws and material licenses, permits and agreements. The
Merger Agreement also expressly prohibits WilTel from engaging in certain
transactions without Leucadia's prior written consent. Among other things,
WilTel has agreed that it will not:

     issue, sell, grant, pledge or otherwise encumber, or redeem, purchase or
     otherwise acquire, any shares of its capital stock, voting securities or
     equity interests, or any securities, options, warrants or rights
     convertible into, or exchangeable or exercisable for, any shares of its
     capital stock, voting securities or equity interests;

     declare, pay any dividend on, or make any other distribution on, any shares
     of its common stock;

     split, combine, subdivide or reclassify any shares of its common stock;

     approve any transfer of shares under Article IV, Section 3 of WilTel's
     articles of incorporation (pertaining to WilTel's tax status under Section
     382 of the Internal Revenue Code), other than the transactions contemplated
     by the Merger Agreement;

     enter into, terminate or amend any agreement that is material to WilTel,
     except in the ordinary course of business consistent with past practice;

     adopt a plan or agreement of complete or partial liquidation, dissolution,
     restructuring, merger or other reorganization; or

     settle or compromise any litigation that is material to WilTel.

CONDUCT OF LEUCADIA'S BUSINESS PRIOR TO COMPLETION OF THE MERGER

    The Merger Agreement contemplates that, until the completion of the merger,
Leucadia will conduct its business in compliance in all material respects with
all applicable laws; will use commercially reasonable efforts to preserve intact
its business organizations and relationships with third parties; and will not:
(i) take any actions that would materially delay the consummation of the merger,
(ii) engage in any material reorganization or (iii) pay or set a record date,
prior to the effective date of the merger, for any extraordinary dividend or
distribution. The Merger Agreement also expressly prohibits Leucadia from
engaging in certain material transactions without WilTel's prior written
consent. Among other things, Leucadia has agreed that until completion of the
merger it will not (without WilTel's consent):

                                       55


     adopt a plan or agreement of complete or partial liquidation, dissolution,
     recapitalization or reclassification;

     dispose of, or enter into an agreement to dispose of, any assets of
     Leucadia which have, individually or in the aggregate, a market or assigned
     value in excess of $750 million;

     offer, sell or otherwise issue or agree to issue any capital stock, or
     securities convertible into or exchangeable for capital stock, of Leucadia
     or its subsidiaries that have, individually or in the aggregate, a market
     or assigned value in excess of $750 million;

     redeem, purchase or otherwise acquire shares of Leucadia capital stock that
     have a market value in excess of $50 million, other than pursuant to
     transactions consistent with past repurchases, redemptions or acquisitions;
     or

     engage in any action with the intent to directly or indirectly adversely
     impact any of the transactions contemplated by the Merger Agreement.

REASONABLE BEST EFFORTS TO COMPLETE THE TRANSACTION

    Subject to the terms of the Merger Agreement, Leucadia and WilTel will use
reasonable best efforts to take, or cause to be taken, all actions necessary to
complete the transactions contemplated by the Merger Agreement.

LIMITATION ON WILTEL'S ABILITY TO CHANGE ITS RECOMMENDATION AND CONSIDER OTHER
TAKEOVER PROPOSALS

    The Merger Agreement provides WilTel's board of directors will not withdraw
or modify its approval or recommendation of the transactions contemplated by the
Merger Agreement in a manner adverse to Leucadia unless WilTel's board of
directors determines in good faith (after consulting with outside counsel) that
such action is necessary in order for WilTel's board of directors to comply with
its fiduciary duties under applicable law. Also, the Merger Agreement requires
that WilTel immediately cease and cause to be terminated any existing
discussions with any third party relating to any proposal or offer from a third
party involving any of the following:

     the direct or indirect acquisition WilTel's assets (including securities of
     subsidiaries, but excluding sales of assets held for sale in the ordinary
     course of business consistent with past practice) equal to 20% or more of
     WilTel's consolidated assets or to which 20% or more of WilTel's revenues
     or earnings on a consolidated basis are attributable;

     the direct or indirect acquisition of 20% or more of any class of equity
     securities of WilTel;

     a tender offer or exchange offer that if consummated would result in any
     person beneficially owning 20% or more of any class of equity securities of
     WilTel; or

     a merger, consolidation, share exchange, business combination,
     recapitalization, liquidation, dissolution or similar transaction involving
     WilTel or any assets of WilTel equal to 20% or more of WilTel's
     consolidated assets or to which 20% or more of WilTel's revenues or
     earnings on a consolidated basis are attributable.

    Any proposal or offer involving the foregoing (other than the transactions
contemplated by the Merger Agreement) is referred to as a 'Takeover Proposal'.

    WilTel has agreed that, except in the circumstances described below, it will
not, directly or indirectly, and it will not authorize or permit any or its
representatives directly or indirectly, to:

     solicit, initiate or knowingly encourage the initiation of (including by
     way of furnishing information that has not been previously publicly
     disseminated) any inquiries or proposals that constitute, or may reasonably
     be expected to lead to, any Takeover Proposal; or

     participate in any discussions with any third party regarding, or furnish
     to any third party any non-public information with respect to, or assist or
     facilitate, any Takeover Proposal.

    However, WilTel may furnish nonpublic information about WilTel (but will use
its best efforts to avoid providing information that may be competitively
harmful to WilTel, taking into

                                       56


consideration the identity of the person making the Takeover Proposal) to, or
participate in discussions with, any third party in response to a bona fide
written Takeover Proposal that is submitted to WilTel by the third party, if:

     the Takeover Proposal is unsolicited and made in circumstances not
     constituting a breach of the Merger Agreement;

     WilTel's board of directors determines in good faith that such Takeover
     Proposal constitutes a Superior Proposal (as defined below);

     WilTel gives Leucadia written notice of the identity of the party making
     the Takeover Proposal and of WilTel's intention to furnish nonpublic
     information to, or enter into discussions with, the third party, and WilTel
     receives from the third party a signed confidentiality agreement containing
     customary protections (and not any provisions calling for an exclusive
     right to negotiate with WilTel); and

     WilTel furnishes the nonpublic information to Leucadia (to the extent
     WilTel has not already done so).

    In addition, WilTel must advise us orally and in writing, if any proposal,
offer, inquiry or other contact is received by, any information is requested
from, or any discussions or negotiations are sought to be initiated or continued
with, WilTel, in respect of any Takeover Proposal. In such notice, WilTel must
indicate the identity of the third party and the terms and conditions of any
proposal, or the nature of any inquiries. WilTel must keep us informed, on a
reasonably current basis, of all material developments affecting the status and
terms of any such proposals.

    For purposes of the Merger Agreement, a 'Superior Proposal' means a bona
fide written proposal made not in breach of the Merger Agreement by a third
party to acquire, directly or indirectly, for consideration consisting of cash
and/or securities, more than 50% of any class of equity securities of WilTel or
more than 50% of the assets of WilTel and its subsidiaries on a consolidated
basis, which is otherwise on terms and conditions which WilTel's board of
directors determines in its good faith and reasonable judgment (after
consultation with a financial advisor of national reputation) to be more
favorable to the holders of WilTel common stock from a financial point of view
than the offer, merger and other transactions contemplated by the Merger
Agreement, taking into account at the time of determination any changes to the
terms of the Merger Agreement that as of that time had been proposed by Leucadia
in writing and the ability and likelihood of the person making such proposal to
consummate the transations contemplated by such proposal in a timely manner
(based upon, among other things, the availability of financing and the
expectation of obtaining required approvals). Any action required to be taken by
WilTel's board of directors under this section shall be performed with the
approval of a majority of the members of the Special Committee then in office.

CONDITIONS TO THE OFFER

    For a list of the conditions to the offer, see 'The Offer -- Conditions of
the Offer'.

CONDITIONS TO THE MERGER

    The obligations of Leucadia and WilTel to complete the merger are subject to
the satisfaction or waiver of the following conditions:

     if required by applicable law or WilTel's articles of incorporation, the
     Merger Agreement shall have been duly adopted by the requisite vote of
     WilTel stockholders;

     no law, injunction, judgment or ruling enacted, issued or entered by any
     governmental entity shall be in effect enjoining, restraining, prohibiting
     or making illegal the consummation of the merger;

     the registration statement on Form S-4 of which this prospectus forms a
     part shall have been declared effective under the Securities Act, and shall
     not be the subject of any stop order or any proceedings seeking a stop
     order;

                                       57


     if required, the Leucadia common shares issuable in the offer and the
     merger shall have been approved for listing on the New York Stock Exchange;
     and

     the minimum condition shall have been satisfied and Leucadia shall have
     exchanged shares of WilTel common stock for Leucadia common shares and CSRs
     in the offer as contemplated under the Merger Agreement.

TERMINATION OF THE MERGER AGREEMENT

    TERMINATION BY MUTUAL AGREEMENT

    Leucadia and WilTel may terminate the Merger Agreement at any time before
the completion of the merger by mutual written consent.

    TERMINATION BY EITHER LEUCADIA OR WILTEL

    Either Leucadia or WilTel may terminate the Merger Agreement any time before
the completion of the merger if:

     a governmental entity has enacted, issued or entered any law prohibiting
     (or making illegal) the offer or the merger, or any injunction, judgment,
     order, decree or ruling or taken any other action permanently enjoining or
     prohibiting the offer or the merger, and such action shall have become
     final and non-appealable, unless the governmental entity's taking of such
     final, non-appealable action was due to a failure by the party seeking to
     terminate the agreement to perform its obligations under the Merger
     Agreement;

     the offer expires without Leucadia having accepted for exchange any shares
     of WilTel common stock pursuant to the offer, unless the failure to accept
     shares is attributable to a failure by the party seeking to terminate the
     agreement to perform its obligations under the Merger Agreement; or

     the acceptance of shares of WilTel common stock for exchange pursuant to
     the offer has not occurred on or before January 15, 2004, unless the
     failure to accept shares of WilTel common stock for exchange pursuant to
     the offer is attributable to a failure by the party seeking to terminate
     the agreement to perform any of its obligation under the Merger Agreement.

    TERMINATION BY LEUCADIA

    We may terminate the Merger Agreement, at any time before the first date on
which we accept any shares of WilTel common stock for exchange pursuant to the
offer, if any of the following occurs:

     WilTel's board of directors has withdrawn or modified, in a manner adverse
     to Leucadia, its approval or recommendation of any of the transactions
     contemplated by the Merger Agreement;

     an event or change occurs that, individually or in the aggregate, has had
     or would reasonably be expected to have a material adverse effect on
     WilTel; or

     WilTel's representations and warranties set forth in the Merger Agreement
     that are qualified as to 'materiality' or material adverse effect are not
     true and correct, or those that are not so qualified are not true and
     correct in all material respects, as of the execution date of the Merger
     Agreement and as of the date of determination as if made on such date, or
     WilTel breaches or fails in any material respect to perform or comply with
     its obligations under the Merger Agreement, and such breach or failure
     cannot be cured or has not been cured within the time periods specified
     under the Merger Agreement.

                                       58


    TERMINATION BY WILTEL

    WilTel may terminate the Merger Agreement before the date shares of WilTel
common stock are first accepted for exchange pursuant to the offer, if:

     an event or change occurs that, individually or in the aggregate, has had
     or would reasonably be expected to have a material adverse effect on
     Leucadia; or

     the representations and warranties of Leucadia set forth in the Merger
     Agreement that are qualified as to 'materiality' or material adverse effect
     are not true and correct, or those that are not so qualified are not true
     and correct in all material respects, as of the execution date of the
     Merger Agreement and as of the date of determination as if made on such
     date, or Leucadia or Merger Sub breaches or fails in any material respect
     to perform or comply with its obligations under the Merger Agreement, and
     such breach or failure cannot be cured or has not been cured within the
     time periods specified under the Merger Agreement.

EXPENSES

    The Merger Agreement provides that all expenses incurred in connection with
the negotiation and execution of the Merger Agreement and the consummation of
the transactions contemplated by the Merger Agreement are to be paid by the
party incurring such expenses.

AMENDMENTS OR SUPPLEMENTS TO THE MERGER AGREEMENT

    The Merger Agreement may be amended or supplemented at any time before the
completion of the merger, even after the Merger Agreement has been approved by
WilTel stockholders. Unless applicable law requires that WilTel stockholders
approve any subsequent amendment or change to the provisions of the Merger
Agreement, such amendment or change may be effected by written agreement of
WilTel and Leucadia by action taken by their respective boards of directors. Any
action by WilTel's board of directors with respect to the amendment or
termination of the Merger Agreement must be approved by a majority of the
members of the Special Committee of the WilTel board of directors.

WAIVERS

    Before the completion of the merger, WilTel or Leucadia may, subject to
applicable law, (i) waive any inaccuracies in the other party's representations
and warranties; (ii) extend the time for the performance of any of the
obligations or acts of the other party; or (iii) waive the other party's
compliance with any provisions or pertinent conditions of the Merger Agreement.
Any such action by WilTel must be approved by a majority of the members of the
Special Committee of the WilTel board of directors.

             COMPARISON OF RIGHTS OF HOLDERS OF WILTEL COMMON STOCK
                     AND HOLDERS OF LEUCADIA COMMON SHARES

INTRODUCTION

    WilTel is incorporated under the laws of the State of Nevada and the rights
of WilTel stockholders are governed by Nevada law and WilTel's articles of
incorporation and by-laws. Leucadia is incorporated under the laws of the State
of New York and the rights of Leucadia's shareholders are governed by New York
law and Leucadia's certificate of incorporation and by-laws. If your shares of
WilTel common stock are exchanged pursuant to the offer or subsequent merger
into Leucadia common shares, your rights as a shareholder will change as a
result of the differences between the respective governing documents of WilTel
and Leucadia and differences between Nevada law and New York law. The following
summary highlights material differences between the current rights of WilTel
stockholders and Leucadia shareholders.

                                       59


    This following comparison of the New York Business Corporation Law and
Leucadia's certificate of incorporation and by-laws, on the one hand, with the
Nevada Revised Statutes and WilTel's articles of incorporation and by-laws, on
the other hand, is intended only to be a summary and not a comprehensive
discussion of rights of either company's shareholders. Copies of our certificate
of incorporation and by-laws and WilTel's articles of incorporation and by-laws
have been filed with the SEC, and this summary is qualified in its entirety by
reference to the specific provisions of these documents. See 'Where You Can Find
More Information'.

AUTHORIZED SHARES; PREFERRED STOCK

    WILTEL

    WilTel's articles of incorporation authorize WilTel to issue 300,000,000
shares of capital stock consisting of 200,000,000 shares of common stock and
100,000,000 shares of preferred stock. Under Nevada law and WilTel's articles of
incorporation, the board of directors has the right to issue preferred shares
with the powers, rights and designations as it may so determine.

    LEUCADIA

    Leucadia's certificate of incorporation authorizes Leucadia to issue
156,000,000 shares of capital stock consisting of 150,000,000 common shares and
6,000,000 preferred shares. Under New York law and Leucadia's certificate of
incorporation, the board of directors has the right to issue preferred shares
with the powers, rights and designations as it may so determine.

VOTING OF STOCKHOLDERS; LIMITATIONS ON SHARE OWNERSHIP

    WILTEL

    Subject to applicable law and WilTel's articles of incorporation, each
WilTel stockholder is entitled to one vote per share of WilTel common stock. In
addition, WilTel's articles of incorporation generally restrict WilTel
stockholders from becoming 5% stockholders (as defined in the articles of
incorporation) or, if they already are 5% stockholders, from increasing their
percentage stock ownership interest or transferring their interests unless such
increase or transfer is approved by the board of directors.

    LEUCADIA

    Subject to applicable law and Leucadia's certificate of incorporation, each
Leucadia shareholder is entitled to one vote per Leucadia common share. In
addition, Leucadia's certificate of incorporation generally restricts Leucadia
shareholders from becoming the owners of 5% of the outstanding Leucadia common
shares or, if they already own 5% of the outstanding Leucadia common shares,
from increasing their percentage ownership interest or transferring their
interests unless such increase or transfer is approved by the board of
directors.

ANNUAL MEETING; SPECIAL MEETINGS OF STOCKHOLDERS

    WILTEL

    Nevada law provides that stockholders meetings are to be held as directed by
the corporation's by-laws and/or articles of incorporation. WilTel's articles of
incorporation and bylaws provide that annual and special meetings of
stockholders may be called only by the board of directors pursuant to a
resolution approved by a majority of the entire board of directors or by certain
persons specified by the by-laws. WilTel's articles of incorporation explicitly
deny any power its stockholders may have under Nevada law to call a special
meeting or to act by written consent.

    WilTel's by-laws provide that, except as otherwise required by law or the
articles of incorporation, a majority of the shares entitled to vote, present in
person or represented by proxy,

                                       60


regardless of whether the proxy has authority to vote on all matters, shall
constitute a quorum at a meeting of stockholders for the transaction of
business.

    LEUCADIA

    New York law provides that shareholder meetings must be held annually and a
special meeting of shareholders may be called by the board of directors or by
persons authorized in the certificate of incorporation or the by-laws.
Leucadia's by-laws provide that the board of directors may call special meetings
of shareholders at any time.

    Leucadia's by-laws provide that, except as otherwise required by law, the
certificate of incorporation or the by-laws, a majority of shares entitled to
vote, present in person or represented by proxy, shall constitute a quorum at a
meeting of shareholders (subject to class voting rights, if any).

ADVANCE NOTICE REQUIREMENTS FOR SHAREHOLDER PROPOSALS AND DIRECTOR NOMINATIONS

    WILTEL

    WilTel's by-laws provide that stockholders seeking to bring business before
an annual meeting of shareholders or to nominate candidates for election as
directors at an annual meeting of stockholders must provide timely notice in
writing. To be timely, a stockholder's notice must be received by WilTel's
corporate secretary:

     not less than 90 nor more than 120 days before the anniversary date of
     immediately preceding annual meeting, or

     if the annual meeting is called for a date that is not within 30 days
     before or after the immediately preceding annual meeting, not later than
     the close of business on the tenth day following the day on which notice of
     the annul meeting is mailed to the stockholders or public disclosure of the
     date of the annual meeting is first made.

    LEUCADIA

    Leucadia's by-laws provide that shareholders seeking to bring business
before an annual meeting of shareholders or to nominate candidates for election
as directors at an annual meeting of shareholders must provide timely notice in
writing. To be timely, a shareholder's notice must be received by Leucadia's
corporate secretary:

     not less than 120 days before the first anniversary date of Leucadia's
     proxy statement in connection with the last annual meeting, or

     if no annual meeting was held in the previous year, not less than a
     reasonable time, as determined by the board of directors, before the date
     of the applicable annual meeting.

REMOVAL OF DIRECTORS; VACANCIES ON THE BOARD OF DIRECTORS

    WILTEL

    Under Nevada law and WilTel's articles of incorporation, a director may be
removed from office by the vote of stockholders representing not less than
two-thirds of the voting power of the issued and outstanding shares entitled to
vote, voting together as a single class.

    Under Nevada law and WilTel's by-laws, a vacancy on the board of directors
may be filled by the affirmative vote of two-thirds of the remaining directors
then in office. See 'Interests of Certain Persons in the Offer and Subsequent
Merger -- Certain Agreements between Leucadia and WilTel' for a description of
certain agreements between Leucadia and WilTel with respect to the WilTel board
of directors. The Stockholders Agreement will terminate upon completion of the
merger.

                                       61


    LEUCADIA

    Under New York law, any director or the entire board of directors may be
removed for cause by holders of a majority of the shares voting on the removal.
Under New York law and Leucadia's by-laws, any director may be removed for cause
by the affirmative vote of a majority of the directors present, provided a
quorum (one-third of the directors) is present.

    Under New York law and Leucadia's by-laws, a vacancy on the board of
directors, other than due to the removal of a director without cause, may be
filled by a vote of the board of directors or if the number of directors then in
office is less than a quorum, by vote of a majority of directors then in office.
A vacancy created by the removal of a director without cause may be filled only
by a vote of the shareholders.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

    WILTEL

    Pursuant to its articles of incorporation and by-laws, WilTel shall
indemnify its current or past directors or officers, to the fullest extent
permitted by Nevada law, for expenses reasonably incurred in any civil, criminal
or administrative proceeding. Nevada law and WilTel's by-laws permit
indemnification only if such director or officer (1) is not liable, and (2)
acted in good faith and in a manner which he reasonably believed to be in or not
opposed to the corporation's best interests and, with respect to any criminal
proceeding, had no reasonable cause to believe that his conduct was unlawful.

    LEUCADIA

    New York law generally permits a corporation to provide indemnification and
advancement of expenses, by by-law provision, agreement or otherwise, against
judgments, fines, expenses and amounts paid in settlement actually and
reasonably incurred by the person in connection with a proceeding if the person
acted in good faith and for a purpose he or she reasonably believed to be in or,
in the case of service for any other corporation or any partnership, joint
venture, trust, employee benefit plan or other enterprise, not opposed to the
best interests of the corporation and, in criminal actions or proceedings, in
addition, had no reasonable cause to believe that his or her conduct was
unlawful.

    Leucadia's by-laws provide for indemnification to the fullest extent
permitted by law.

SHAREHOLDER APPROVAL OF BUSINESS COMBINATIONS

    WILTEL

    Under Nevada law, a business combination may be approved by the affirmative
vote of holders of shares representing a majority of the outstanding voting
power. A business combination is defined broadly to include a merger or
consolidation, sale, lease, exchange or other disposition of corporation
property exceeding threshold aggregate market values, or a dissolution of the
corporation.

    In addition, WilTel's articles of incorporation provide that until the
earlier of December 15, 2007 and the Expiration Date (as defined in the articles
of incorporation), if a majority of the members of WilTel's board of directors
are not Continuing Directors (as defined in the articles of incorporation), in
addition to any approvals required by law, the prior approval of either (i) the
holders of 75% of the issued and outstanding voting securities of WilTel, or
(ii) a vote of a majority of the Continuing Directors, will be required for the
consummation of a Business Combination Transaction (as defined in the articles
of incorporation), unless certain conditions are satisfied. If the offer is
successfully consummated, this provision will no longer be applicable.

                                       62


    LEUCADIA

    Under New York law, for corporations in existence on February 22, 1998,
whose certificate of incorporation expressly provides, or for corporations
formed after that date, the holders of a majority of the shares entitled to vote
must approve a merger or consolidation, sale, lease, exchange or other
disposition of all or substantially all of the property of the corporation not
in the usual and regular course of the corporation's business, or a dissolution
of the corporation. In the case of all other corporations, like Leucadia,
approval by the holders of two-thirds of the votes of all outstanding shares
entitled to vote is required.

AMENDMENT OF GOVERNING DOCUMENTS

    WILTEL

    Under Nevada law, amendments to the articles of incorporation must be
adopted in accordance with the following procedures:

     the board of directors must adopt a resolution setting forth the amendment
     and declaring its advisability;

     the board of directors must call a meeting, providing notice to each
     stockholder entitled to vote as to the meeting and the amendment to be
     considered; and

     unless the articles of incorporation provide otherwise, the amendment may
     be approved by the holders of a majority of the voting power entitled to
     vote on the amendment.

    WilTel's articles of incorporation provide that the affirmative vote of at
least (a) 75% of the combined voting power of the then outstanding shares of
WilTel common stock shall be required to amend or repeal the restriction
regarding Business Combination Transaction, (b) 80% of the combined voting power
shall be required to amend or repeal the provisions of the articles of
incorporation granting the board of directors exclusive authority to call
special meetings of stockholders and prohibiting stockholder action by written
consent, (c) 66 2/3% of the combined voting power shall be required to amend or
repeal the provisions of the articles of incorporation relating to the removal
of directors in office, and (d) a majority of the shares of WilTel common stock
shall be required to amend the other provisions of the articles of
incorporation.

    Nevada law provides that, subject to any by-laws adopted by the
stockholders, the board of directors may adopt the by-laws of the corporation.
Nevada law is silent on the amendment or repeal of by-laws. WilTel's articles of
incorporation and by-laws provide that, generally, by-laws may be adopted,
altered, amended or repealed by a majority vote of the entire board of directors
or the holders of outstanding common stock or preferred stock entitled to vote
thereon. Any proposed alteration of certain provisions relating to stockholders
meetings, director elections, or the amendment of WilTel's by-laws, however,
must be approved by an affirmative vote of at least 80% of the entire board of
directors or stockholders entitled to vote.

    LEUCADIA

    Under New York law, an amendment to the certificate of incorporation
requires the approval of the corporation's board of directors and the
affirmative vote of a majority of the outstanding shares entitled to vote,
provided that (1) provisions in the certificate of incorporation requiring a
greater vote on a matter may be amended only with that greater vote and (2) the
affirmative vote of a majority of the outstanding shares of classes of stock
that would be adversely affected is required, in addition to the foregoing, in
certain circumstances.

    Under New York law, the board of directors may amend by-laws if so
authorized in the charter or a by-law adopted by the shareholders or the
incorporators. Leucadia's by-laws authorize the board of directors to amend
by-laws by a vote of the majority of directors present at a meeting at which a
quorum is present. The shareholders of a New York corporation also have the
power to amend by-laws, by majority vote of shares outstanding and entitled to
vote in an election of directors.

                                       63


STATE ANTI-TAKEOVER STATUTES

    WILTEL

    Nevada law includes two anti-takeover statutes:

     the combinations with interested stockholders statutes; and

     the acquisition of controlling interest statutes.

    WilTel has adopted provisions in its articles of incorporation to 'opt-out'
of these combinations with interested stockholders statutes. Thus, the statutes
are generally not applicable to business combinations involving WilTel.

    LEUCADIA

    New York law includes an anti-takeover statute that restricts the ability of
a New York corporation to engage in a business combination with an interested
shareholder for a period of five years following such interested shareholder's
stock acquisition date. Under New York law, an interested shareholder is defined
as the beneficial owner of 20% or more of the corporation's shares or an
affiliate or associate of the corporation who has, within the previous five
years, beneficially owned 20% or more of the corporation's then outstanding
shares.

    AGREEMENT AND PLAN OF MERGER (this 'Agreement'), dated as of August 21, 2003
(the 'Execution Date'), among LEUCADIA NATIONAL CORPORATION, a New York
corporation ('Parent'), WRANGLER ACQUISITION CORP., a Nevada corporation and
wholly owned subsidiary of Parent ('Merger Sub'), and WILTEL COMMUNICATIONS
GROUP, INC., a Nevada corporation (the 'Company'). Certain terms used in this
Agreement are used as defined in Section 8.11.

    WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company each deems it advisable that Parent acquire the Company on the terms and
subject to the conditions provided for in this Agreement;

    WHEREAS, in furtherance thereof it is proposed that such acquisition be
accomplished by (a) Parent commencing an exchange offer to acquire all of the
shares of common stock, $.01 par value, of the Company ('Company Common Stock')
issued and outstanding (each, a 'Share' and, collectively, the 'Shares') that
are not beneficially owned (within the meaning of Rule 13d-3 under the
Securities Exchange Act of 1934, as amended, and the rules and regulations
promulgated thereunder (the 'Exchange Act')) by Parent (each, a 'Public Share'
and, collectively, the 'Public Shares'), in which exchange offer each Public
Share validly tendered and not properly withdrawn would be exchanged for
(i) 0.4242 (such exchange ratio, or any greater exchange ratio, per Public Share
paid pursuant to the Offer being hereinafter referred to as the 'Exchange
Ratio') of a common share, $1.00 par value, of Parent ('Parent Common Stock')
(such amount of shares, or any greater amount of shares, of Parent Common Stock
paid per Public Share pursuant to the Offer being hereinafter referred to as the
'Base Offer Consideration') and (ii) one Contingent Sale Right having the terms
described in Section 2.11 hereof (as it may be amended in accordance with this
Agreement, a 'CSR' and, together with the Base Offer Consideration, the 'Offer
Consideration'), in each case, subject to any required withholding of taxes, on
the terms and subject to the conditions provided for in this Agreement (such
exchange offer, as it may be amended from time to time as permitted by this
Agreement, the 'Offer'), and (b) following the consummation of the Offer, the
merger of Merger Sub with and into the Company, with the Company being the
surviving corporation, in accordance with the Nevada Revised Statutes (the
'NRS'), pursuant to which Shares (other than certain shares as provided in
Section 2.7(b) hereof) will be converted into the right to receive the Offer
Consideration, subject to any required withholding of taxes, on the terms and
subject to the conditions provided for in this Agreement (the 'Merger');

    WHEREAS, for federal income tax purposes, it is intended that the Offer and
the Merger shall qualify as a reorganization within the meaning of Section
368(a) of the Internal Revenue Code of 1986, as amended (the 'Code'); and

    WHEREAS, the respective Boards of Directors of Parent (on its own behalf and
as the sole stockholder of Merger Sub), Merger Sub and the Company have each
adopted this Agreement and approved the Offer and the Merger.

    NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements contained in this Agreement, and intending to be
legally bound hereby, Parent, Merger Sub and the Company hereby agree as
follows:

                                   ARTICLE I

                                   THE OFFER

    1.1 The Offer.

    (a) Provided that (i) none of the events or circumstances set forth in
paragraphs (a) through (f) of Annex A hereto shall have occurred and be existing
(and shall not have been waived by Parent) and (ii) the Company shall have
complied with its obligations under Section 1.2 hereof, Parent shall commence
(within the meaning of Rule 14d-2 under the Exchange Act) the Offer as promptly
as reasonably practicable after the Execution Date, but in no event later than
10 business days after the Execution Date.

                                      A-1


    (b) The obligation of Parent to accept for exchange, and to exchange the
Offer Consideration for, Public Shares tendered pursuant to the Offer shall be
subject only (i) to the satisfaction of the condition that at the expiration of
the Offer there be validly tendered in accordance with the terms of the Offer
(other than Shares tendered by guaranteed delivery where actual delivery has not
occurred) and not withdrawn that number of Public Shares which represents more
than 50% of the Public Shares then outstanding, subject to Section 1.1(g) hereof
the 'Minimum Condition'), and (ii) to the satisfaction (or waiver by Parent) of
the other conditions set forth in Annex A hereto. Parent expressly reserves the
right to waive any of such conditions (other than the Minimum Condition and the
condition set forth in clause (vi) of the second paragraph of Annex A hereto),
to increase the consideration per Public Share payable in the Offer and to make
any other changes in the terms of the Offer; provided, however, that no change
may be made without the prior written consent of the Company which decreases the
Exchange Ratio for the Offer from that set forth in the second 'Whereas' clause
hereof (or decreases the number of shares of Parent Common Stock issuable
pursuant to the CSRs), changes the form of consideration to be paid in the
Offer, reduces the maximum number of Shares sought to be acquired in the Offer,
imposes conditions to the Offer in addition to the conditions set forth in Annex
A hereto, waives the Minimum Condition or the condition set forth in clause (vi)
of the second paragraph of Annex A hereto, or modifies or amends any of the
conditions set forth in Annex A hereto or makes other changes in the terms of
the Offer that are in any manner adverse to the holders of Public Shares or,
except as provided below, extends the expiration date of the Offer.
Notwithstanding the foregoing, Parent may (A) extend the Offer beyond the
initial scheduled expiration date, which shall be 20 business days following the
date of commencement of the Offer, or any subsequent scheduled expiration date,
if, at the scheduled expiration of the Offer, any of the conditions to Parent's
obligation to accept for exchange, and to exchange the Offer Consideration for,
Public Shares tendered shall not be satisfied or, to the extent permitted by
this Agreement, waived, subject, however, to the parties' respective rights to
terminate this Agreement pursuant to Section 7.1, and (B) extend the Offer for
any period required by any rule, regulation or interpretation of the Securities
and Exchange Commission (the 'SEC') or the staff thereof applicable to the
Offer. Each extension of the Offer pursuant to clause (A) of the preceding
sentence shall not exceed the lesser of ten business days (or such longer period
as the Company and Parent may agree in writing in any particular instance) or
such fewer number of days that Parent reasonably believes are necessary to cause
the conditions of the Offer set forth in Annex A hereto to be satisfied. In
addition, if, at the expiration date of the Offer, all of the conditions to the
Offer have been satisfied (or, to the extent permitted by this Agreement, waived
by Parent) but the number of Public Shares validly tendered and not withdrawn
pursuant to the Offer, when taken together with Shares, if any, then
beneficially owned by Parent, constitutes less than 90% of the Shares then
outstanding, without the consent of the Company, Parent shall (subject to
applicable law) have the right to provide for a 'subsequent offering period' (as
contemplated by Rule 14d-11 under the Exchange Act) for up to 20 business days
after Parent's acceptance for exchange of the Public Shares then tendered and
not withdrawn pursuant to the Offer, in which event Parent shall (I) give the
required notice of such subsequent offering period and (II) immediately accept
for exchange, and promptly exchange the Offer Consideration for, all Public
Shares tendered and not withdrawn as of such expiration date.

    (c) Subject to the terms of the Offer and this Agreement and the
satisfaction or earlier waiver of all the conditions of the Offer set forth in
Annex A hereto as of any expiration date of the Offer, Parent shall accept for
exchange, and exchange the Offer Consideration (subject to any required
withholding of taxes) for, all Public Shares validly tendered and not withdrawn
pursuant to the Offer promptly after it is permitted to do so under applicable
law.

    (d) Notwithstanding anything to the contrary set forth herein, no
certificates or scrip representing fractional shares of Parent Common Stock
shall be issued in connection with the Offer, no dividends or other
distributions with respect to Parent Common Stock shall be payable on or with
respect to any such fractional share interest and such fractional share
interests will not entitle the owner thereof to vote or to any other rights of a
stockholder of Parent. In lieu thereof, each tendering stockholder who would
otherwise be entitled to a fractional share of Parent

                                      A-2


Common Stock (after aggregating all fractional shares of Parent Common Stock
that otherwise would have been received by such stockholder) will be entitled to
receive an amount in cash (without interest) equal to such holder's
proportionate interest in the net proceeds from the sale or sales in the open
market by the Exchange Agent (as hereinafter defined), on behalf of such
holders, of the aggregated fractional shares of Parent Common Stock issued
pursuant to this paragraph. Promptly following the Purchase Date, (i) the
Exchange Agent shall determine the total amount of the fractional shares of
Parent Common Stock to which all such tendering stockholders would otherwise be
entitled, and aggregate the same into whole shares of Parent Common Stock
(rounded up to the nearest whole share), (ii) Parent shall issue such whole
shares of Parent Common Stock to the Exchange Agent, as agent for such tendering
stockholders, and (iii) the Exchange Agent shall sell such shares of Parent
Common Stock at the then prevailing prices on the New York Stock Exchange
through one or more member firms of the New York Stock Exchange (which sales
shall be executed in round lots to the extent practicable). Until the net
proceeds of such sales have been distributed to such tendering stockholders, the
Exchange Agent will hold such proceeds in trust for such holders. Promptly after
the determination of the amount of cash to be paid to such holders in lieu of
any fractional interests in Parent Common Stock, the Exchange Agent shall pay
such amounts to such holders (subject to any required withholding of taxes).

    (e) The Company agrees that no Shares held by the Company or any of its
subsidiaries will be tendered to Parent pursuant to the Offer.

    (f) As promptly as practicable on the date of commencement of the Offer,
Parent shall file with the SEC (i) a Tender Offer Statement on Schedule TO with
respect to the Offer (together with all amendments, supplements and exhibits
thereto, the 'Schedule TO') and (ii) a registration statement on Form S-4 to
register, under the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (the 'Securities Act'), the offer and sale of
Parent Common Stock pursuant to the Offer and the Merger (together with all
amendments, supplements and exhibits thereto, the 'Registration Statement'). The
Registration Statement shall include a prospectus (the 'Prospectus') containing
the information required under Rule 14d-4(b) promulgated under the Exchange Act.
The Schedule TO shall include or contain as an exhibit an offer to exchange and
form of the related letter of transmittal and all other ancillary Offer
documents (collectively with the Prospectus, and together with all amendments,
supplements and exhibits thereto and to the Prospectus, the 'Offer Documents').
Parent shall cause the Offer Documents to be disseminated to the holders of the
Public Shares as and to the extent required by applicable federal securities
laws. Parent, on the one hand, and the Company, on the other hand, shall
promptly correct any information provided by it for use in the Offer Documents
if and to the extent that it shall be or shall have become false or misleading
in any material respect, and Parent shall cause the Offer Documents as so
corrected to be filed with the SEC and disseminated to holders of the Public
Shares, in each case, as and to the extent required by applicable federal
securities laws. The Company and its counsel shall be given a reasonable
opportunity to review and comment upon the Offer Documents before they are filed
with the SEC and disseminated to holders of Public Shares. In addition, Parent
agrees to provide the Company and its counsel with any comments, whether written
or oral, that Parent or its counsel may receive from time to time from the SEC
or its staff with respect to the Offer Documents promptly after the receipt of
such comments, to consult with the Company and its counsel prior to responding
to any such comments and to provide the Company with copies of all such
responses, whether written or oral. Following the time the Registration
Statement is declared effective, Parent shall file the final prospectus included
therein under Rule 424(b) promulgated pursuant to the Securities Act.

    (g) If none of the Shares held by the securities holder channeling fund
established in connection with Second Amended and Restated Joint Plan of
Reorganization of Williams Communications Group, Inc. and CG Austria Inc. are
validly tendered in accordance with the terms of the Offer and not withdrawn at
the expiration of the Offer, then the Shares in such fund shall be deemed not
outstanding for purposes of the Minimum Condition.

                                      A-3


    1.2 Company Actions.

    (a) The Company hereby represents and warrants that the Company's Board of
Directors, at a meeting duly called and held, has (i) adopted this Agreement and
approved the Transactions, including the Offer and the Merger, and
(ii) resolved (subject to Section 5.2 hereof) to recommend that holders of
Public Shares accept the Offer, tender their Public Shares to Parent pursuant
thereto and approve this Agreement. The Company hereby consents to the inclusion
in the Offer Documents of the recommendation of the Company's Board of Directors
described in the immediately preceding sentence. The Company hereby further
represents and warrants that (A) the Board of Directors of the Company has
received the opinion of JPMorgan, dated the Execution Date, to the effect that,
as of such date, and subject to the various assumptions and qualifications set
forth therein, the consideration to be received by the holders of the Public
Shares in the Offer and the Merger is fair to such holders from a financial
point of view (the 'Fairness Opinion') and (B) the Company has been authorized
by JPMorgan to permit the inclusion of the Fairness Opinion and/or references
thereto in the Offer Documents, the Schedule 14D-9 and any Proxy Statement,
subject to prior review and consent by JPMorgan (such consent not to be
unreasonably withheld or delayed).

    (b) As promptly as practicable on the date of commencement of the Offer, the
Company shall file with the SEC a Solicitation/Recommendation Statement on
Schedule 14D-9 (together with all amendments, supplements and exhibits thereto,
the 'Schedule 14D-9') which shall contain the recommendation of the Board of
Directors of the Company referred to in Section 1.2(a). The Company shall cause
the Schedule 14D-9 to be disseminated to holders of the Public Shares as and to
the extent required by applicable federal securities laws. The Company, on the
one hand, and Parent, on the other hand, shall promptly correct any information
provided by it for use in the Schedule 14D-9 if and to the extent that it shall
be or shall have become false or misleading in any material respect, and the
Company shall cause the Schedule 14D-9 as so corrected to be filed with the SEC
and disseminated to holders of the Public Shares, in each case, as and to the
extent required by applicable federal securities laws. Parent and its counsel
shall be given a reasonable opportunity to review and comment upon the
Schedule 14D-9 before it is filed with the SEC and disseminated to holders of
Public Shares. In addition, the Company agrees to provide Parent and its counsel
with any comments, whether written or oral, that the Company or its counsel may
receive from time to time from the SEC or its staff with respect to the
Schedule 14D-9 promptly after the receipt of such comments, to consult with
Parent and its counsel prior to responding to any such comments and to provide
Parent with copies of all such responses, whether written or oral.

    (c) The Company agrees (i) to promptly upon Parent's request provide all
information about the Company required to be disclosed in the Offer Documents,
(ii) to promptly deliver to Parent a duly executed consent of the Company's
accountants to allow Parent to include in the Registration Statement the
Company's financial statements and such accountants' report thereon, (iii) that
all information provided by the Company for inclusion or incorporation by
reference in the Offer Documents will not (at the respective times such
materials, or any amendments or supplements thereto, are filed with the SEC,
first published, sent or given to stockholders of the Company, the Offer expires
or shares of Parent Common Stock are delivered in connection with the Offer, or
at the Effective Time, as the case may be) contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading, and (iv) to promptly
correct any information provided by the Company for the Offer Documents if and
to the extent that such information shall have become false or misleading in any
material respect.

    (d) The Company shall promptly furnish Parent with mailing labels containing
the names and addresses of all record holders of Shares and with security
position listings of Shares held in stock depositories, each as of a recent
date, together with all other available listings and computer files containing
names, addresses and security position listings of record holders and beneficial
owners of Shares. The Company shall furnish Parent with such additional
information, including updated

                                      A-4


listings and computer files of stockholders, mailing labels and security

reasonably require in communicating the Offer to the record and beneficial
holders of Shares.

                                      A-5


Certificate of Merger (the time at which the Merger becomes effective is herein
referred to as the 'Effective Time').

    2.4 Effects of the Merger. From and after the Effective Time, the Merger
shall have the effects set forth in the NRS. Without limiting the generality of
the foregoing, and subject thereto, at the Effective Time, all the properties,
rights, privileges, powers and franchises of the Company and Merger Sub shall
vest in the Surviving Corporation, and all debts, liabilities and duties of the
Company and Merger Sub shall become the debts, liabilities and duties of the
Surviving Corporation.

    At the Effective Time, each of (i) the Stockholders Rights and Co-Sale
Agreement, dated as of October 15, 2002, between Parent and the Company and
(ii) the Stockholders Agreement (as hereinafter defined) shall terminate and be
of no further force or effect.

    2.5 Articles of Incorporation and By-laws of the Surviving Corporation. At
the Effective Time, (a) the articles of incorporation of the Company as in
effect immediately prior to the Effective Time shall be the articles of
incorporation of the Surviving Corporation until thereafter amended as provided

Merger Sub and the officers of the Company, respectively, immediately prior to

accordance with the articles of incorporation and by-laws of the Surviving
Corporation.

    2.7 Conversion of Securities. At the Effective Time, by virtue of the Merger
and without any action on the part of the holders of any securities of Merger
Sub or the Company:

        (a) Each then issued and outstanding share of capital stock of Merger
    Sub shall be converted into and become one validly issued, fully paid and
    nonassessable share of common stock, $.0l par value, of the Surviving
    Corporation.

        (b) Any Shares that are owned by the Company as treasury stock, and all
    Shares owned by Parent or any subsidiary of Parent, shall be automatically
    canceled and retired and shall cease to exist and no consideration shall be
    delivered in exchange therefor.

        (c) Each issued and outstanding Share (other than (i) Shares to be
    canceled in accordance with Section 2.7(b) and (ii) any Dissenting Shares
    (as hereinafter defined)), shall be converted into the right to receive
    (A) one CSR and (B) the Exchange Ratio of a share of Parent Common Stock,
    issuable to the holder thereof upon surrender, in the manner provided in
    this Agreement, of the certificate formerly representing such Share, without
    interest (the 'Merger Consideration'). As of the Effective Time, all such
    Shares shall no longer be outstanding and shall automatically be canceled
    and retired and shall cease to exist, and each holder of a certificate which
    immediately prior to the Effective Time represented any such Shares (each, a
    'Certificate') shall cease to have any rights with respect thereto, except
    the right to receive the Merger Consideration, any dividends or other
    distributions to which such holder is entitled pursuant to Section 2.8(c)
    and cash in lieu of any fractional shares of Parent Common Stock to which
    such holder is entitled pursuant to Section 2.8(e), in each case to be
    issued or paid in consideration therefor upon surrender of such Certificate
    in accordance with Section 2.8(b), without interest.

    2.8 Exchange of Certificates.

    (a) Exchange Agent. As of the Effective Time, Parent shall deposit with
American Stock Transfer & Trust Company or such other bank or trust company as
may be designated by Parent (the 'Exchange Agent'), for exchange in accordance
with this Article II, through the Exchange Agent, certificates representing the
shares of Parent Common Stock issuable pursuant to Section 2.7 in exchange for
shares of Company Common Stock (such shares of Parent Common Stock, together
with any dividends or other distributions with respect thereto with a record
date

                                      A-6


after the Effective Time and any cash payments in lieu of any fractional shares
of Parent Common Stock, being hereinafter referred to as the 'Exchange Fund').
The Exchange Agent shall invest any cash included in the Exchange Fund as
directed by Parent. Any interest and other income resulting from such
investments shall be the property of, and shall be paid to, Parent.

    (b) Exchange Procedures. As soon as reasonably practicable after the
Effective Time, Parent shall cause the Exchange Agent to mail to each holder of
record of a Certificate whose shares of Company Common Stock were converted into
the right to receive the Merger Consideration pursuant to Section 2.7(c), (i) a
form of letter of transmittal (which shall specify that delivery shall be
effected, and risk of loss and title to the Certificates shall pass, only upon
delivery of the Certificates to the Exchange Agent and which shall be in such
form and shall have such other provisions as Parent may specify) and
(ii) instructions for use in surrendering the Certificates in exchange for
certificates representing the Merger Consideration, any dividends or other
distributions to which holders of Certificates are entitled pursuant to
Section 2.8(c) and cash in lieu of any fractional shares of Parent Common Stock
to which such holders are entitled pursuant to Section 2.8(e). Upon surrender of
a Certificate for cancellation to the Exchange Agent, together with such letter
of transmittal, duly completed and validly executed, and such other documents as
may be reasonably required by the Exchange Agent, the holder of such Certificate
shall be entitled to receive in exchange therefor (A) a certificate representing
that number of whole shares of Parent Common Stock that such holder has the
right to receive pursuant to the provisions of this Article II after taking into
account all the shares of Company Common Stock held by such holder under all
such Certificates so surrendered, (B) any dividends or other distributions to
which such holder is entitled pursuant to Section 2.8(c) and (C) cash in lieu of
any fractional shares of Parent Common Stock to which such holder is entitled
pursuant to Section 2.8(e), and the Certificate so surrendered shall forthwith
be canceled. In the event of a transfer of ownership of shares of Company Common
Stock that is not registered in the transfer records of the Company, a
certificate representing the proper number of shares of Parent Common Stock may
be issued to a person other than the person in whose name the Certificate so
surrendered is registered, if, upon presentation to the Exchange Agent, such
Certificate shall be properly endorsed or otherwise be in proper form for
transfer and the person requesting such issuance shall pay any transfer or other
taxes required by reason of the issuance of shares of Parent Common Stock to a
person other than the registered holder of such Certificate or establish to the
reasonable satisfaction of the Exchange Agent that such tax has been paid or is
not applicable. Until surrendered as contemplated by this Section 2.8(b), each
Certificate shall be deemed at any time after the Effective Time to represent
only the right to receive upon such surrender the Merger Consideration, any
dividends or other distributions to which the holder of such Certificate is
entitled pursuant to Section 2.8(c) and cash in lieu of any fractional shares of
Parent Common Stock to which such holder is entitled pursuant to
Section 2.8(e). No interest will be paid or will accrue on any cash payable to
holders of Certificates pursuant to Section 2.8(c) or (e).

    (c) Distributions with Respect to Unexchanged Shares. No dividends or other
distributions with respect to Parent Common Stock with a record date after the
Effective Time shall be paid to the holder of any unsurrendered Certificate with
respect to the shares of Parent Common Stock that the holder thereof has the
right to receive upon the surrender thereof, and no cash payment in lieu of any
fractional shares of Parent Common Stock shall be paid to any such holder
pursuant to Section 2.8(e), in each case until the holder of such Certificate
shall surrender such Certificate in accordance with this Article II. Following
surrender of any Certificate, there shall be paid to the record holder thereof
the certificate representing whole shares of Parent Common Stock issued in
exchange therefor, without interest, (i) at the time of such surrender, the
amount of cash payable in lieu of any fractional shares of Parent Common Stock
to which such holder is entitled pursuant to Section 2.8(e) and the amount of
dividends or other distributions payable with respect to such whole shares of
Parent Common Stock with a record date after the Effective Time and paid with
respect to Parent Common Stock prior to such surrender and (ii) at the
appropriate payment date, the amount of dividends or other distributions with a
record date after the Effective Time but prior to such surrender and a payment
date subsequent to such surrender payable with respect to such whole shares of
Parent Common Stock.

                                      A-7


    (d) No Further Ownership Rights in Company Common Stock. All shares of
Parent Common Stock issued upon the surrender for exchange of Certificates in
accordance with the terms of this Article II (including any dividends or other
distributions paid pursuant to Section 2.8(c) and cash paid in lieu of any
fractional shares pursuant to Section 2.8(e)) shall be deemed to have been
issued (and paid) in full satisfaction of all rights pertaining to the shares of
Company Common Stock previously represented by such Certificates, and at the
close of business on the day on which the Effective Time occurs, the stock
transfer books of the Company shall be closed and there shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Company Common Stock that were outstanding
immediately prior to the Effective Time. Subject to the last sentence of
Section 2.8(f), if, at any time after the Effective Time, Certificates are
presented to the Surviving Corporation or the Exchange Agent for any reason,
they shall be canceled and exchanged as provided in this Article II.

    (e) No Fractional Shares. Notwithstanding anything to the contrary set forth
herein, no certificates or scrip representing fractional shares of Parent Common
Stock shall be issued in connection with the Merger, no dividends or other
distributions with respect to Parent Common Stock shall be payable on or with
respect to any such fractional share interest and such fractional share
interests will not entitle the owner thereof to vote or to any other rights of a
stockholder of Parent. In lieu thereof, each former holder of shares of Company
Common Stock who would otherwise have been entitled to such a fractional share
interest (after aggregating all fractional shares of Parent Common Stock that
otherwise would have been received by such holder) will be entitled to receive
an amount in cash (without interest) equal to such holder's proportionate
interest in the net proceeds from the sale or sales in the open market by the
Exchange Agent, on behalf of such holders, of the aggregated fractional shares
of Parent Common Stock issued pursuant to this paragraph. Promptly following the
Effective Time, (i) the Exchange Agent shall determine the total amount of the
fractional shares of Parent Common Stock to which all such former Company
stockholders would otherwise be entitled, and aggregate the same into whole
shares of Parent Common Stock (rounded up to the nearest whole share), (ii)
Parent shall issue such whole shares of Parent Common Stock to the Exchange
Agent, as agent for such former stockholders, and (iii) the Exchange Agent shall
sell such shares of Parent Common Stock at the then prevailing prices on the New
York Stock Exchange through one or more member firms of the New York Stock
Exchange (which sales shall be executed in round lots to the extent
practicable). Until the net proceeds of such sales have been distributed to such
former stockholders, the Exchange Agent will hold such proceeds in trust for
such holders. Promptly after the determination of the amount of cash to be paid
to such former stockholders in lieu of any fractional interests in Parent Common
Stock, the Exchange Agent shall pay such amounts to such former stockholders
(subject to any required withholding of taxes).

    (f) Termination of Exchange Fund. Any portion of the Exchange Fund that
remains undistributed to the holders of the Certificates for six months after
the Effective Time shall be delivered to Parent, upon demand, and any holders of
Certificates who have not theretofore complied with this Article II shall
thereafter look only to Parent for payment of their claim for the Merger
Consideration, any dividends or other distributions with respect to shares of
Parent Common Stock and cash in lieu of any fractional shares of Parent Common
Stock in accordance with this Article II. If any Certificate shall not have been
surrendered immediately prior to such date on which any Merger Consideration
(and dividends or other distributions payable pursuant to Section 2.8(c) and
cash payable in lieu of fractional shares pursuant to Section 2.8(e)) would
otherwise escheat to or become the property of any Governmental Entity, any such
Merger Consideration (and dividends or other distributions payable pursuant to
Section 2.8(c) and cash payable in lieu of fractional shares pursuant to
Section 2.8(e)) in respect thereof shall, to the extent permitted by applicable
law, become the property of Parent, free and clear of all claims or interest of
any person previously entitled thereto.

    (g) No Liability. None of Parent, Merger Sub, the Company or the Exchange
Agent shall be liable to any person in respect of any CSRs or any shares of
Parent Common Stock (or dividends or other distributions with respect thereto)
or cash in lieu of any fractional shares of Parent

                                      A-8


Common Stock or cash from the Exchange Fund, in each case delivered to a public
official pursuant to any applicable abandoned property, escheat or similar law.

    (h) Lost Certificates. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by Parent, the
posting by such person of a bond in such reasonable amount as Parent may direct
as indemnity against any claim that may be made against it with respect to such
Certificate, the Exchange Agent will issue in exchange for such lost, stolen or
destroyed Certificate the Merger Consideration, any dividends or other
distributions to which the holder of such Certificate would be entitled pursuant
to Section 2.8(c) and cash in lieu of any fractional shares of Parent Common
Stock to which such holder would be entitled pursuant to Section 2.8(e), in each
case pursuant to this Agreement.

    (i) Withholding Rights. The Exchange Agent shall be entitled to deduct and
withhold from the consideration otherwise payable to any holder of shares of
Company Common Stock pursuant to this Agreement such amounts as may be required
to be deducted and withheld with respect to the making of such payment under the
Code or under any provision of state or foreign tax law. To the extent that
amounts are so withheld and paid over to the appropriate taxing authority, the
Exchange Agent will be treated as though it withheld from the type of
consideration from which withholding is required an appropriate amount otherwise
payable pursuant to this Agreement to any holder of shares of Company Common
Stock in order to provide for such withholding obligation. If withholding is
required from shares of Parent Common Stock, the Exchange Agent shall be treated
as having sold such consideration for an amount of cash equal to the fair market
value of such consideration at the time of such deemed sale and paid such cash
proceeds to the appropriate taxing authority.

    2.9 Appraisal Rights. Notwithstanding anything in this Agreement to the
contrary, if appraisal rights are available under Section 92A.380 of the NRS in
respect of the Merger, then Shares that are issued and outstanding immediately
prior to the Effective Time and which are held by stockholders who have demanded
and perfected their demands for appraisal of such Shares in the time and manner
provided in Sections 92A.300 through 92A.500 (inclusive) of the NRS and, as of
the Effective Time, have neither effectively withdrawn nor lost their rights to
such appraisal and payment under the NRS (the 'Dissenting Shares'), shall not be
converted as described in Section 2.7(c) hereof, but shall, by virtue of the
Merger, be entitled to only such rights as are granted by Section 92A.380 of the
NRS; provided, that if such holder shall have failed to perfect or shall have
effectively withdrawn or lost his, her or its right to appraisal and payment
under the NRS, such holder's Shares shall thereupon be deemed to have been
converted, at the Effective Time, as described in Section 2.7(c), into the right
to receive the Merger Consideration, without any interest thereon. The Company
shall give Parent (i) prompt notice of any written demands for appraisal of any
Shares, attempted withdrawals of such demands and any other instruments served
pursuant to the NRS and received by the Company relating to stockholders' rights
of appraisal, and (ii) the opportunity to participate in all negotiations and
proceedings with respect to demands for appraisal under the NRS. Prior to the
Effective Time, the Company shall not, except with the prior written consent of
Parent, voluntarily make any payment with respect to, or settle, or offer or
agree to settle, any such demand for payment. Any funds paid to holders of
Dissenting Shares shall be paid solely out of the assets of the Surviving
Corporation and Parent shall not contribute funds to Merger Sub or the Surviving
Corporation to fund payments to holders of Dissenting Shares, assume the
Surviving Corporation's obligation to make such payment, or otherwise reimburse
the Surviving Corporation, directly or indirectly, for such payment. Any portion
of the Merger Consideration made available to the Exchange Agent pursuant to
Section 2.8 to pay for Shares for which appraisal rights have been perfected
shall be returned to Parent upon demand.

    2.10 Exchange Ratio. Notwithstanding anything to the contrary, if between
the Execution Date and the Effective Time, the outstanding shares of Parent
Common Stock shall have been changed into a different number of shares or a
different class, by reason of the occurrence or record date of any stock
dividend, subdivision, reclassification, recapitalization, split, combination,
exchange of shares or similar transaction, the Exchange Ratio shall be
appropriately adjusted to reflect such

                                      A-9


stock dividend, subdivision, reclassification, recapitalization, split,
combination, exchange of shares or similar transaction.

    2.11 CSRs.

    (a) Subject to the terms and conditions of this Agreement, the consideration
payable by Parent per share of Company Common Stock in the Offer and Merger will
include one CSR. As described in greater detail below, the purpose of the CSRs
is to give Company stockholders who participate in the Offer and Merger the
opportunity to receive additional Parent Common Stock in connection with any
Sale of the Company (as hereinafter defined) consummated after the Effective
Time and on or before the Maturity Date (as hereinafter defined) in which Parent
or its subsidiaries receive Net Proceeds (as hereinafter defined) in excess of
the Deal Price (as hereinafter defined).

    (b) The CSRs will be uncertificated contract rights and will be
non-assignable and non-transferable by any holder thereof, except as required by
any applicable community property laws or laws of descent and distribution.

    (c) The CSRs will become effective at the Effective Time and will mature at
11:59 p.m. New York City time on the earlier of (i) the date, if any, on which a
Sale of the Company for Net Proceeds in excess of the Deal Price is consummated
and (ii) October 15, 2004, provided that if after the Effective Time and prior
to the first anniversary of the Execution Date Parent or the Surviving
Corporation shall have entered into a definitive agreement with an unaffiliated
third party providing for a Sale of the Company (a 'Sale Contract'), the date in
this clause (ii) shall be the later of (A) October 15, 2004 and (B) the earlier
of (x) the date the Sale of the Company pursuant to such Sale Contract is
consummated and (y) the date such Sale of the Company is abandoned (the earlier
of (i) and (ii) being the 'Maturity Date').

    For purposes of the CSRs, 'Sale of the Company' means the occurrence of any
of the following events: (i) a sale by the Surviving Corporation of all or
substantially all of the assets of the Surviving Corporation and its
subsidiaries to another entity (other than Parent or one or more of its
subsidiaries ('Permitted Holders')), including any such sale of assets to a
Permitted Holder that is done as part of a related sale of such assets to an
entity that is not a Permitted Holder; (ii) any 'person' or 'group', other than
Permitted Holders, is or becomes the 'beneficial owner', directly or indirectly,
of more than 50% of the issued and outstanding shares of capital stock of the
Surviving Corporation having general voting power under ordinary circumstances
('Voting Stock'); or (iii) the Surviving Corporation consolidates with, or
merges with or into, another Person (other than a Permitted Holder), other than
any such transaction where (A) the outstanding Voting Stock of the Surviving
Corporation is converted into or exchanged for voting securities of the
surviving entity and (B) immediately after such transaction Permitted Holders
are the 'beneficial owners', directly or indirectly, of more than 50% of the
total voting power of the surviving entity. For purposes of this definition, the
term 'beneficial owner' is used as defined in Rules 13d-3 and 13d-5 under the
Exchange Act and the terms 'person' or 'group' are used as such terms are used
in Section 13(d) and 14(d) of the Exchange Act. For the avoidance of doubt, only
the consummation of the transactions described above in this definition shall
constitute a 'Sale of the Company' and neither any discussions, negotiations or
preparations, nor entering into any agreement, relating to any such transaction
shall be deemed a 'Sale of the Company'.

    (d) If there is consummated after the Effective Time and on or before the
Maturity Date a Sale of the Company for Net Proceeds in excess of the Deal
Price, then, following the Maturity Date, Parent will issue for each CSR that
number of whole shares of Parent Common Stock (after aggregating all CSRs held
by the holder thereof) determined under the following formula (calculated to the
fourth decimal point) and paragraphs (e) and (f) of this Section 2.11:


                         
             Sale Profit
             -----------    divided by Parent Price
             50,000,000


          provided, however, that in no event shall more than a total of the Cap
          Number (as hereinafter defined) of shares of Parent Common Stock be
          issuable in respect of all CSRs in the aggregate, and the number of
          shares of Parent Common Stock issuable to each

                                      A-10


          CSR holder shall be reduced pro rata to the extent necessary to give
          effect to this limitation

where,

        'Sale Profit' means the amount of Net Proceeds in excess of the Deal
    Price;

        'Net Proceeds' means the US$ amount (expressed as a whole number) of
    aggregate proceeds (with any non-cash proceeds to be valued at their fair
    market value as determined in good faith by the Board of Directors of
    Parent) received by Parent, the Surviving Corporation or any of their
    subsidiaries in respect of a Sale of the Company consummated after the
    Effective Time and on or before the Maturity Date, plus the fair market
    value (to be determined in good faith by the Board of Directors of Parent)
    of any assets of the Surviving Corporation or its subsidiaries retained by
    Parent upon consummation of such Sale of the Company, net of (i) the costs
    relating to such transaction (including, without limitation, regulatory
    filing fees, legal, accounting and investment banking fees, and brokerage
    and sales commissions), (ii) taxes paid or payable as a result of such
    transaction, (iii) amounts required to be applied to the repayment of
    principal, premium (if any) and interest on any indebtedness required to be
    paid as a result of such transaction, (iv) deduction of appropriate amounts
    to be provided as a reserve in accordance with GAAP against any liabilities
    associated with such transaction (including, without limitation, pension and
    other post-employment benefit liabilities and liabilities related to
    environmental matters or against any indemnification obligations associated
    with such transaction) and (v) all liabilities of the Surviving Corporation
    or its subsidiaries that are retained by Parent or any of its subsidiaries
    following consummation of such transaction;

        'Deal Price' equals (A) 800,000,000, plus (B) the aggregate US$ amount
    (expressed as a whole number) of contributions to capital and other
    investments made by Parent or any of its affiliates (other than the
    Surviving Corporation and its subsidiaries) in, and expenditures funded by
    Parent or any of its affiliates (other than the Surviving Corporation and
    its subsidiaries) in support of, the Surviving Corporation or its
    subsidiaries after the Effective Time and prior to the Maturity Date, minus
    (C) the aggregate US$ amount (expressed as a whole number) of dividends paid
    by the Surviving Corporation to Parent after the Effective Time and prior to
    the Maturity Date, plus (D) an amount equal to notional interest on the
    excess, if any, of (i) the amounts described in clause (B) above over
    (ii) the amount described in clause (C) above, at a rate per annum of 8%,
    determined based on the number of days elapsed from the Closing Date to the
    Maturity Date and a 360-day year;

        'Parent Price' equals 37.72, reduced to reflect the amount (if any) of
    cash dividends per share of Parent Common Stock paid (or with a record date)
    between the Execution Date and the Maturity Date in excess of Parent's
    regular $0.25 per share annual dividend; and

        'Cap Number' means the lesser of (A) 11,000,000 and (B) the number of
    shares of Parent Common Stock issued by Parent in the Offer and the Merger
    (excluding consideration paid to holders of Dissenting Shares) minus one.

    (e) If, on the Maturity Date, Net Proceeds are equal to or less than the
Deal Price, the CSRs shall automatically terminate and no consideration shall be
deliverable in respect thereof. If, on the Maturity Date, the amount determined
pursuant to the formula in Section 2.11(d) above is greater than zero, Parent
will thereafter issue to each CSR holder the number of whole shares of Parent
Common Stock to which such holder is entitled as herein described (rounded down
to the nearest whole share, after aggregating all CSRs held by such holder), and
the CSRs shall be automatically cancelled.

    (f) Notwithstanding anything to the contrary, if between the Effective Time
and the Maturity Date the outstanding shares of Parent Common Stock shall have
been changed into a different number of shares or a different class, by reason
of the occurrence or record date of any stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange of shares or
similar transaction, then the number of and kind of shares issuable in respect
of the CSRs shall be

                                      A-11


appropriately adjusted to reflect such stock dividend, subdivision,
reclassification, recapitalization, split, combination, exchange of shares or
similar transaction.

    (g) If shares of Parent Common Stock become issuable under the CSRs, Parent
will determine the amount required under applicable tax laws to be treated as
interest income, and may, at its option, issue two stock certificates to each
holder of CSRs, one certificate in respect of the shares treated as interest and
the other certificate in respect of the remaining shares; provided, however,
that in no event will Leucadia issue any fractional share interests.

    (h) All computations and determinations relating to the CSRs shall be made
by Parent in good faith. Promptly after the Maturity Date, Parent shall notify
holders of CSRs in writing (which notification may be made through a press
release which will be attached to a submission that is made publicly available
on the SEC's EDGAR system) of Parent's determination as to (i) whether a Sale of
the Company occurred after the Effective Time and on or before the Maturity
Date, (ii) the amount of any Net Proceeds received in respect thereof,
(iii) the amount (if any) of any resulting Sale Profit, and (iv) the number of
shares of Parent Common Stock (if any) due and payable to CSR holders under this
Agreement ((i) through (iv) collectively, the 'Relevant Determinations').
Following such notice, CSR holders shall have 180 days to communicate to Parent
in writing any objections to Parent's determination of the Relevant
Determinations; provided that a CSR holder may object to Parent's determinations
only (A) on the basis that Parent's determinations, including determinations
regarding fair market value in the definition of 'Net Proceeds' being made in
good faith, were not made in accordance with this Agreement, (B) to the extent
that if such holder's objection was upheld, Parent would be required to issue an
aggregate of at least 25,000 more shares of Parent Common Stock in respect of
the CSRs than would be issuable according to Parent's determinations and (C) if
the bases for such holder's objection are specified in writing and in reasonable
detail (an 'Objection Notice'). If Parent receives one or more Objection
Notices, then Parent and the CSR holders who delivered such Objection Notice
shall discuss the objections set forth therein in good faith and Parent agrees,
and each CSR holder, by accepting a CSR agrees, to use all reasonable efforts to
ensure that any final resolution of such objections will be applicable to, and
binding on, all CSR holders (and not only those CSR holders who objected to
Parent's determinations). If shares are issued or other amounts are paid in
settlement of one or more Objection Notices, then all objecting and
non-objecting CSR holders shall, to the extent practicable, be treated equally
by Parent and receive the same amount and form of consideration as the objecting
CSR holders, based on and in proportion to the number of CSRs held by each such
holder. If any such objections are not resolved by the date that is 270 days
after the Maturity Date, then Parent and the CSR holders shall submit the matter
to an Agreed Court for resolution through appropriate proceedings, provided that
Parent and such holders shall use all reasonable efforts to ensure that such
proceedings are conducted as a class action such that any final resolution in
such proceedings will be applicable to, and binding on, all CSR holders (and not
only those CSR holders who objected to Parent's determinations), provided
further that, if class action status is not available for such proceedings,
Parent agrees, and each CSR holder, by accepting a CSR agrees, to use all
reasonable efforts to ensure that any final resolution in such proceedings will
be applicable to, and binding on, all CSR holders (and not only those CSR
holders who objected to Parent's determinations). By accepting a CSR, each CSR
holder irrevocably waives any rights to trial by jury in any legal proceeding
related to the CSRs.

    (i) The holder of a CSR will not be entitled to any of the rights of a
stockholder in Parent (including, without limitation, voting and dividend
rights).

    (j) No dividends or other distributions with respect to Parent Common Stock
with a record date before the Maturity Date will be paid in respect of, and no
interest will be paid or will accrue on, any shares of Parent Common Stock
issuable in respect of CSRs. None of Parent or any of its subsidiaries shall be
liable to any person in respect of any shares of Parent Common Stock issuable in
respect of CSRs delivered to a public official pursuant to any applicable
abandoned property, escheat or similar law.

                                      A-12


    (k) Notwithstanding anything to the contrary, Parent shall be free to
conduct its business (including, without limitation, all decisions relating to
whether, when, how and for what consideration to dispose of any assets) as it in
its sole discretion shall determine.

and is in good standing in each jurisdiction in which the nature of the business
conducted by it or the character or location of the properties and assets owned

Adverse Effect'). For purposes of this Agreement, the term 'Material Adverse
Effect' shall mean, with respect to any party, a state of facts, effect, event

by any subsidiary of the Company) and no shares of Company Preferred Stock
issued and outstanding. All Shares have been duly authorized and validly issued
and are fully paid and nonassessable. Since the Execution Date, the Company has

the Effective Time, and (3) comply in all material respects with all applicable
Laws and the requirements of all licenses, Permits, leases, agreements and other
instruments that are material to the Company and its subsidiaries taken as a
whole. Any transaction specifically approved by Ian M. Cumming and Joseph S.

constitute Parent approval for purposes of this Section 5.1(a). Without limiting
the generality of the foregoing, during the period from the Execution Date to
the Effective Time, the Company shall not, and shall not permit any of its
subsidiaries to, without the prior written consent of Parent:

    set aside for payment or pay any dividend on, or make any other distribution

    similar agreement;

        (iii) make (x) any changes in financial or tax accounting methods,
    principles or practices, except insofar as may be required by a change in
    GAAP or applicable Law, or (y) any material Tax election;

        (iv) adopt a plan or agreement of complete or partial liquidation,
    dissolution, restructuring, recapitalization, merger, consolidation or other
    reorganization (other than transactions exclusively between wholly owned
    subsidiaries of the Company);

        (v) settle or compromise any litigation or proceeding material to the
    Company and its subsidiaries taken as a whole (this covenant being in
    addition to the Company's agreement set forth in Section 5.8 hereof); or

        (vi) agree, in writing or otherwise, to take any of the foregoing
    actions or take any action or agree, in writing or otherwise, to take any

    or Material Adverse Effect to be untrue and (B) that are not so qualified to
    be untrue in any material respect.

    (b) Parent agrees that, during the period from the Execution Date until the
Effective Time, except as expressly contemplated or permitted by this Agreement
or as required by applicable Law, or unless the Company otherwise agrees in
writing, Parent shall, and shall cause each of its subsidiaries to, conduct
their business in compliance in all material respects with all applicable laws

Agreement, (2) engage in any material recapitalization or restructuring of
Parent or (3) pay or set a record date prior to the Effective Time relating to

        (i) adopt a plan or agreement or complete or partial liquidation,

    stock) any corporation, partnership or other person or division or business
    unit thereof or any equity interest therein of Parent or its subsidiaries if
    such disposition would relate to assets that have, individually or in the
    aggregate, a market or assigned value in excess of $750 million;

        (iv) offer, sell or otherwise issue or agree to issue any capital stock
    of Parent or its subsidiaries, including securities convertible into or
    exchangeable for Parent Common Stock or stock of one or more of Parent's

    assigned value in excess of $750 million (other than in connection with the
    transactions contemplated by this Agreement);

        (v) redeem, purchase or otherwise acquire directly or indirectly shares

publicly to withdraw or modify, in a

                                      A-20


manner adverse to Parent, the approval or recommendation by such Board of
Directors described in the first sentence of Section 1.2(a) hereof.
Notwithstanding the foregoing, the Board of Directors of the Company may
withdraw or modify its recommendation described in Section 1.2(a) if such Board
determines in good faith, after reviewing applicable provisions of state law and
after consulting with outside counsel, that such action is necessary in order
for such Board to comply with its fiduciary duties under applicable law.

    5.3 Reasonable Best Efforts.

    Subject to the terms and conditions of this Agreement (including
Section 5.3(d)), the Company and Parent shall each cooperate with the other and
use (and shall cause their respective subsidiaries to use) their respective
reasonable best efforts to promptly (i) take or cause to be taken all actions,
and do or cause to be done all things, necessary, proper or advisable under this
Agreement and applicable Laws to consummate the Transactions as soon as
practicable, including preparing and filing promptly and fully all documentation
to effect all necessary filings, notices, petitions, statements, registrations,
submissions of information, applications and other documents (including any
required or recommended filings under applicable Antitrust Laws (as hereinafter
defined)) and (ii) obtain all approvals, consents, registrations, permits,
authorizations and other confirmations from any Governmental Entity or third
party necessary, proper or advisable to consummate the Transactions. For
purposes hereof, 'Antitrust Laws' means the Sherman Act, as amended, the Clayton
Act, as amended, the HSR Act, the Federal Trade Commission Act, as amended, and
all other applicable Laws issued by a Governmental Entity that are designed or
intended to prohibit, restrict or regulate actions having the purpose or effect
of monopolization or restraint of trade or lessening of competition through
merger or acquisition.

    In furtherance and not in limitation of the foregoing, (i) each party hereto
agrees to make an appropriate filing of a Notification and Report Form pursuant
to the HSR Act with respect to the Transactions as promptly as practicable and
in any event within five business days of the Execution Date and to supply as
promptly as practicable any additional information and documentary material that
may be requested pursuant to the HSR Act and use its reasonable best efforts to
take, or cause to be taken, all other actions consistent with this Section 5.3
necessary to cause the expiration or termination of the applicable waiting
periods under the HSR Act as soon as practicable; (ii) each of the parties shall
use its reasonable best efforts to have the Registration Statement declared
effective under the Securities Act as promptly as practicable and keep the
Registration Statement effective for so long as necessary to consummate the
Merger (it being understood that this covenant shall not be construed to require
Parent to file a general consent to service of process, or to qualify to do
business in any jurisdiction in which it is not now so qualified); and
(iii) the Company shall use its reasonable best efforts to (x) take all action
necessary to ensure that no state takeover statute or similar Law is or becomes
applicable to any of the Transactions and (y) if any state takeover statute or
similar Law becomes applicable to any of the Transactions, take all action
necessary to ensure that the Transactions may be consummated as promptly as
practicable on the terms contemplated by this Agreement and otherwise minimize
the effect of such Law on the Transactions.

    Each of Parent and the Company shall use its reasonable best efforts to
(i) cooperate in all respects with each other in connection with any filing or
submission with a Governmental Entity in connection with the Transactions and in
connection with any investigation or other inquiry by or before a Governmental
Entity relating to the Transactions, including any proceeding initiated by a
private party, and (ii) keep the other party informed in all material respects
and on a reasonably timely basis of any material communication received by such
party from, or given by such party to, the Federal Trade Commission, the
Antitrust Division of the Department of Justice or any other Governmental Entity
and of any material communication received or given in connection with any
proceeding by a private party, in each case regarding any of the Transactions.

    In furtherance and not in limitation of the covenants of the parties
contained in this Section 5.3, each of Parent and the Company shall use its
reasonable best efforts to resolve such objections, if any, as may be asserted
by a Governmental Entity or other Person with respect to the Transactions.
Notwithstanding the foregoing or any other provision of this Agreement, the

                                      A-21


Company shall not, without Parent's prior written consent, commit to any
divestiture transaction, and nothing in this Section 5.3 shall (i) limit any
applicable rights a party may have to terminate this Agreement pursuant to
Section 7.1 so long as such party has up to then complied in all material
respects with its obligations under this Section 5.3, (ii) require Parent to
offer, accept or agree to (A) dispose or hold separate any part of its or the
Company's businesses, operations, assets or product lines (or a combination of
Parent's and the Company's respective businesses, operations, assets or product
lines), (B) not compete in any geographic area or line of business, and/or
(C) restrict the manner in which, or whether, Parent, the Company, the Surviving
Corporation or any of their affiliates may carry on business in any part of the
world or (iii) require any party to this Agreement to contest or otherwise
resist any administrative or judicial action or proceeding, including any
proceeding by a private party, challenging any Transaction as violative of any
Antitrust Law.

    5.4 Public Announcements. The initial press release with respect to the
execution of this Agreement shall be a joint press release to be reasonably
agreed upon by Parent and the Company. Thereafter, except as may be required by
Law or by any applicable listing agreement with a national securities exchange
or NASDAQ as determined in the good faith judgment of the party proposing to
make such release, neither the Company nor Parent shall issue or cause the
publication of any press release or other public announcement (to the extent not
previously issued or made in accordance with this Agreement) with respect to the
Offer, the Merger, this Agreement or the other Transactions without the prior
consent of the other party (which consent shall not be unreasonably withheld or
delayed).

    5.5 Access; Confidentiality. Upon reasonable notice and subject to
applicable Laws relating to the exchange of information, the Company shall, and
shall cause each of its subsidiaries to, afford to the officers, employees,
accountants, counsel, financial advisors and other representatives of Parent,
during the period from the Execution Date until the Effective Time, access to
all its properties, books, contracts, commitments and records, and to its
officers, employees, accountants, counsel, financial advisors and other
representatives and, during such period, the Company shall, and shall cause its
subsidiaries to, make available to Parent (a) a copy of each report, schedule,
registration statement and other document filed or received by it during such
period pursuant to the requirements of Federal securities laws and (b) all other
information concerning its business, properties and personnel as Parent may
reasonably request; provided that no investigation shall affect or modify any
representation or warranty of the Company. Until the Effective Time, such
information provided will be subject to the terms of Section 3.6 of the
Stockholders Agreement.

    5.6 Notification of Certain Matters. The Company shall give prompt notice to
Parent, and Parent shall give prompt notice to the Company, of (i) any notice or
other communication received by such party from any Governmental Entity in
connection with the Transactions or from any Person alleging that the consent of
such Person is or may be required in connection with the Transactions, if the
subject matter of such communication or the failure of such party to obtain such
consent could be material to the Company, the Surviving Corporation or Parent,
(ii) any orders, actions, suits, claims, investigations or proceedings commenced
or, to such party's knowledge, threatened against, relating to or involving or
otherwise affecting such party or any of its subsidiaries which relate to the
Transactions, (iii) the discovery of any fact or circumstance that, or the
occurrence or non-occurrence of any event the occurrence or non-occurrence of
which, would cause any representation or warranty made by such party contained
in this Agreement (A) that is qualified as to materiality or Material Adverse
Effect to be untrue and (B) that is not so qualified to be untrue in any
material respect, and (iv) any material failure of such party to comply with or
satisfy any covenant or agreement to be complied with or satisfied by it
hereunder; provided, however, that the delivery of any notice pursuant to this
Section 5.6 shall not (x) (nor shall any information provided pursuant to
Section 5.5) be considered in determining whether any representation or warranty
is true for purposes of Section 7.1 or the conditions to the Offer, (y) cure any
breach or non-compliance with any other provision of this Agreement or
(z) limit the remedies available to the party receiving such notice.

                                      A-22


    5.7 Director and Officer Indemnification.

    From and after the Effective Time, Parent and the Surviving Corporation
shall (i) indemnify the individuals who at or prior to the Effective Time were
directors or officers of the Company (collectively, the 'Indemnitees') with
respect to all acts or omissions by them in their capacities as such at any time
prior to the Effective Time, to the fullest extent (A) required by the Company
Charter Documents as in effect on the Execution Date and (B) permitted under
applicable Law.

    For a three year period commencing immediately after the Effective Time,
Parent and the Surviving Corporation shall maintain in effect directors' and
officers' liability insurance covering acts or omissions occurring prior to the
Effective Time with respect to those persons who are currently covered by the
Company's current primary directors' and officers' liability insurance policy,
on terms with respect to such coverage not less favorable to the Company's
directors and officers currently covered by such insurance than those of such
policy in effect on the Execution Date (or Parent or the Surviving Corporation
may substitute therefore insurance policies, issued by reputable carriers, with
respect to matters occurring prior to the Effective Time); provided, however,
that the aggregate amount of coverage under such insurance shall be limited to
$10 million. For those amounts of directors' and officers' liability insurance
in excess of the insurance described in the preceding sentence which are
currently provided under the Company's other current directors' and officers'
liability insurance policies (the 'Other Policies'), for a six year period
commencing immediately after the Effective Time, Parent agrees to make payments
to those persons who are currently covered by such Other Policies to the extent
such payments otherwise would have been made under such Other Policies (as in
effect on the Execution Date) had such Other Policies remained in effect for a
period of six years following the Effective Time, with respect to acts or
omissions occurring prior to the Effective Time; provided, however, that the
maximum amount of payments that Parent and the Surviving Corporation shall be
required to make shall not exceed $50 million in the aggregate.

    The Indemnitees to whom this Section 5.7 applies shall be third party
beneficiaries of this Section 5.7. The provisions of this Section 5.7 are
intended to be for the benefit of each Indemnitee and his heirs.

    5.8 Securityholder Litigation. The Company shall give Parent the opportunity
to participate in the defense or settlement of any securityholder litigation
against the Company and/or its directors relating to the Transactions, and no
such settlement shall be agreed to without Parent's prior consent.

    5.9 Offer Documents; Schedule 14D-9; Proxy Statement. Without limiting any
other provision of this Agreement, whenever any party hereto becomes aware of
any matter, event or change which is required to be set forth in an amendment or
supplement to the Offer Documents, the Schedule 14D-9 and/or the Proxy
Statement, such party shall promptly inform the other parties thereof and each
of the parties shall cooperate in the preparation, filing with the SEC and (as
and to the extent required by applicable federal securities laws) dissemination
to the Company's stockholders of such amendment or supplement.

    5.10 Other Offers.

    (a) The Company shall immediately cease, and shall cause its subsidiaries
and the Company's and its subsidiaries' respective directors, officers,
employees, investment bankers, attorneys, accountants and other representatives
to cease, any discussions or negotiations with any Person that may be ongoing
with respect to a Takeover Proposal (as hereinafter defined) and demand in
writing the return from all such Persons or the destruction of all copies of
confidential information provided to such Persons by the Company or its
representatives that are still in the possession of such Persons. The Company
shall not, and shall cause its subsidiaries and the Company's and its
subsidiaries' respective directors, officers, employees, investment bankers,
attorneys, accountants and other representatives not to, directly or indirectly
(i) solicit, initiate or knowingly encourage the initiation of (including by way
of furnishing information that has not been previously publicly disseminated)
any inquiries or proposals that constitute, or may reasonably be expected to
lead to, any Takeover Proposal or (ii) participate in any discussions with any
third party regarding, or

                                      A-23


furnish to any third party any non-public information with respect to, or assist
or facilitate, any Takeover Proposal; provided, however, that if the Board of
Directors of the Company receives an unsolicited, bona fide written Takeover
Proposal that was made in circumstances not involving a breach of this Agreement
and that the Board of Directors of the Company determines in good faith
constitutes a Superior Proposal (as hereinafter defined), then the Company may
(but only prior to the Purchase Date), in response to such Takeover Proposal and
after providing Parent not less than 24 hours written notice of its intention to
take such actions, (A) furnish to the Person making such Takeover Proposal
information (including non-public information, provided that the Company shall
use its best efforts to avoid providing information that may be competitively
harmful to the Company, taking into consideration the identity of such Person)
with respect to the Company, but only after such Person enters into a customary
confidentiality agreement with the Company, provided that (1) such
confidentiality agreement may not include any provision calling for an exclusive
right to negotiate with the Company and (2) the Company advises Parent of all
such non-public information delivered to such Person concurrently with its
delivery to such Person and concurrently with its delivery to such Person the
Company delivers to Parent all such information not previously provided to
Parent, and (B) participate in discussions and negotiations with such Person
regarding such Takeover Proposal.

    (b) In addition to the other obligations of the Company set forth in this
Section, the Company shall promptly advise Parent, orally and in writing, and in
no event later than 48 hours after receipt, if any proposal, offer, inquiry or
other contact is received by, any information is requested from, or any
discussions or negotiations are sought to be initiated or continued with, the
Company in respect of any Takeover Proposal, and shall, in any such notice to
Parent, identify the Person making such proposal, offer, inquiry or other
contact and the terms and conditions of any proposals or offers or the nature of
any inquiries or contacts, and thereafter shall keep Parent informed, on a
reasonably current basis, of all material developments affecting the status and
terms of any such proposals, offers, inquiries or requests and of the status of
any such discussions or negotiations.

    (c) For purposes of this Agreement:

        'Takeover Proposal' shall mean any bona fide written proposal or offer
    from any Person (other than Parent and its subsidiaries) relating to any
    (A) direct or indirect acquisition (whether in a single transaction or a
    series of related transactions) of assets of the Company and its
    subsidiaries (including securities of subsidiaries, but excluding sales of
    assets held for sale in the ordinary course of business consistent with past
    practice) equal to 20% or more of the Company's consolidated assets or to
    which 20% or more of the Company's revenues or earnings on a consolidated
    basis are attributable, (B) direct or indirect acquisition (whether in a
    single transaction or a series of related transactions) of 20% or more of
    any class of equity securities of the Company, (C) tender offer or exchange
    offer that if consummated would result in any Person beneficially owning 20%
    or more of any class of equity securities of the Company or (D) merger,
    consolidation, share exchange, business combination, recapitalization,
    liquidation, dissolution or similar transaction involving the Company or
    involving any subsidiary (or subsidiaries) or any assets of the Company and
    its subsidiaries equal to 20% or more of the Company's consolidated assets
    or to which 20% or more of the Company's revenues or earnings on a
    consolidated basis are attributable; in each case, other than the
    Transactions.

        'Superior Proposal' shall mean a bona fide written proposal made not in
    breach of this Agreement by a third party to acquire, directly or
    indirectly, for consideration consisting of cash and/or securities, more
    than 50% of any class of equity securities of the Company or more than 50%
    of the assets of the Company and its subsidiaries on a consolidated basis,
    which is otherwise on terms and conditions which the Board of Directors of
    the Company determines in its good faith and reasonable judgment (after
    consultation with a financial advisor of national reputation) to be more
    favorable to the holders of Shares from a financial point of view than the
    Offer, the Merger and the other Transactions, taking into account at the
    time of determination any changes to the terms of this Agreement that as of
    that time

                                      A-24


    had been proposed by Parent in writing and the ability and likelihood of the
    Person making such proposal to consummate the transactions contemplated by
    such proposal in a timely manner (based upon, among other things, the
    availability of financing and the expectation of obtaining required
    approvals). Any action required to be taken by the Company's Board of
    Directors pursuant to this Section 5.10 shall be performed with Director
    Approval.

        5.11 Rule 16b-3. Parent and the Company shall take such steps as may be
    reasonably requested by any party hereto to cause dispositions of Company
    equity securities pursuant to the transactions contemplated by this
    Agreement by each individual who is a director or officer of the Company to
    be exempt under Rule 16b-3 promulgated under the Exchange Act and the rules
    and regulations promulgated thereunder in accordance with that certain No-
    Action Letter dated January 12, 1999 issued by the SEC regarding such
    matters.

        5.12 Tax Matters.

        (a) Each of Parent, Merger Sub and the Company shall provide to Weil,
    Gotshal & Manges LLP and Gibson, Dunn & Crutcher LLP a certificate
    containing representations reasonably requested by such counsel in
    connection with the opinion referred to in clause (vi) of the second
    paragraph of Annex A hereto.

        (b) During the period from the Execution Date until the Effective Time,
    none of Parent, Merger Sub or the Company shall take any action, or permit
    their respective subsidiaries to take any action, that should reasonably be
    expected to prevent the Offer and the Merger from qualifying as a
    reorganization within the meaning of Section 368(a) of the Code.

                                   ARTICLE VI

                            CONDITIONS TO THE MERGER

or prior to the Effective Time of the following conditions:

        (a) This Agreement shall have been duly adopted by the requisite vote of

    enjoining, restraining, preventing or prohibiting consummation of the Merger
    or making the consummation of the Merger illegal;

        (c) The Registration Statement shall have become effective under the
    Securities Act and shall not be the subject of any stop order or proceedings
    seeking a stop order;

        (d) If such approval is necessary, the shares of Parent Common Stock
    issuable to the stockholders of the Company in the Merger as contemplated by
    this Agreement shall have been approved for listing on the New York Stock
    Exchange, subject to official notice of issuance; and

        (e) The Minimum Condition shall have been satisfied and Parent shall
    have purchased Public Shares pursuant to the Offer, provided that this
    condition shall be deemed satisfied with respect to Parent if Parent shall
    have failed to purchase Public Shares pursuant to the Offer in breach of its
    obligations under this Agreement.

                                  ARTICLE VII

    action shall have become final and non-appealable; provided, that the right
    to terminate this Agreement under this Section 7.1(b)(i) shall not be
    available to a party if the issuance of such final, non-appealable
    injunction, judgment, order, decree or ruling was primarily due to the
    failure of such party to perform any of its obligations under this
    Agreement;

        (ii) if the Offer shall have expired pursuant to its terms (and not have
    been extended by Parent in accordance with Section 1.1 hereof) without any

    8.2 Amendment or Supplement.

    (a) At any time prior to the Effective Time, this Agreement may be amended

Boards of Directors (which in the case of the Company shall include the Director
Approval contemplated by Section 8.2(b)); provided, however, that following
approval of the transactions contemplated hereby by stockholders of the Company
there shall be

                                      A-27


no amendment or change to the provisions hereof which by Law would require

Directors of the Company established May 27, 2003 then in office ('Director
Approval') shall be required to authorize (i) any amendment or termination of
this Agreement by the Company, (ii) any extension by the Company of time for

conditions; provided, however, in the case of the Company until the Effective
Time, the Director Approval contemplated by Section 8.2(b) is obtained.
Notwithstanding the foregoing, no failure or delay by the Company, Parent or
Merger Sub in exercising any right hereunder shall operate as a waiver thereof
nor shall any single or partial exercise thereof preclude any other or further

the part of a party hereto to any such extension or waiver shall be valid only
if set forth in an instrument in writing signed on behalf of such party.

hereto and their respective successors and permitted assigns. Any purported
assignment not permitted under this Section shall be null and void.

    8.5 Counterparts; Effectiveness. This Agreement may be executed in two or
more separate counterparts, each of which shall be deemed to be an original but
all of which taken together shall constitute one and the same agreement. This
Agreement shall become effective when each party hereto shall have received
counterparts hereof signed by the other parties hereto.

    8.6 Entire Agreement; No Third-Party Beneficiaries. This Agreement, together

    (c) Each of the parties hereto (i) consents to submit itself to the personal

               (II) Any other entity which, at the effective date of the plan of
           merger or exchange, were either listed on a national securities
           exchange, included in the national market system by the National
           Association of Securities Dealers, Inc., or held of record by a least
           2,000 holders of owner's interests of record; or

to shares registered to stockholder; assertion by beneficial stockholder.

    1. A stockholder of record may assert dissenter's rights as to fewer than
all of the shares registered in his name only if he dissents with respect to all
shares beneficially owned by any one person and notifies the subject corporation
in writing of the name and address of each person on whose behalf he asserts
dissenter's rights. The rights of a partial dissenter under this subsection are
determined as if the shares as to which he dissents and his other shares were
registered in the names of different stockholders.

    2. A beneficial stockholder may assert dissenter's rights as to shares held
on his behalf only if:

        (a) He submits to the subject corporation the written consent of the
    stockholder of record to the dissent not later than the time the beneficial
    stockholder asserts dissenter's rights; and

        (b) He does so with respect to all shares of which he is the beneficial
    stockholder or over which he has power to direct the vote.

    NRS 92A.410 Notification of stockholders regarding right of dissent.

stockholders are or may be entitled to assert dissenters' rights under
NRS 92A.300 to 92A.500, inclusive, and be accompanied by a copy of those
sections.

    2. If the corporate action creating dissenters' rights is taken by written
consent of the stockholders or without a vote of the stockholders, the domestic
corporation shall notify in writing all stockholders entitled to assert
dissenters' rights that the action was taken and send them the dissenter's
notice described in NRS 92A.430.

    NRS 92A.420 Prerequisites to demand for payment for shares.

    and requires that the person asserting dissenter's rights certify whether or
    not he acquired beneficial ownership of the shares before that date;

        (d) Set a date by which the subject corporation must receive the demand
    for payment, which may not be less than 30 nor more than 60 days after the

where required, each by the date set forth in the dissenter's notice, is not

those rights are canceled or modified by the taking of the proposed corporate
action.

of a demand for payment, the subject corporation shall pay each dissenter who
complied with NRS 92A.440 the amount the subject corporation estimates to be the
fair value of his shares, plus accrued interest. The obligation of the subject

        (a) Of the county where the corporation's registered office is located;
    or

        (b) At the election of any dissenter residing or having its registered
    office in this state, of the county where the dissenter resides or has its
    registered office. The court shall dispose of the complaint promptly.

    2. The payment must be accompanied by:

        (a) The subject corporation's balance sheet as of the end of a fiscal
    year ending not more than 16 months before the date of payment, a statement
    of income for that year, a statement of changes in the stockholders' equity
    for that year and the latest available interim financial statements, if any;

        (b) A statement of the subject corporation's estimate of the fair value
    of the shares;

        (c) An explanation of how the interest was calculated;

        (d) A statement of the dissenter's rights to demand payment under
    NRS 92A.480; and

        (e) A copy of NRS 92A.300 to 92A.500, inclusive.

                                      C-4


    NRS 92A.470 Payment for shares: Shares acquired on or after date of
dissenter's notice.

    1. A subject corporation may elect to withhold payment from a dissenter
unless he was the beneficial owner of the shares before the date set forth in
the dissenter's notice as the date of the first announcement to the news media
or to the stockholders of the terms of the proposed action.

    2. To the extent the subject corporation elects to withhold payment, after
taking the proposed action, it shall estimate the fair value of the shares, plus
accrued interest, and shall offer to pay this amount to each dissenter who
agrees to accept it in full satisfaction of his demand. The subject corporation
shall send with its offer a statement of its estimate of the fair value of the
shares, an explanation of how the interest was calculated, and a statement of
the dissenters' right to demand payment pursuant to NRS 92A.480.

    NRS 92A.480 Dissenter's estimate of fair value: Notification of subject
corporation; demand for payment of estimate.

    1. A dissenter may notify the subject corporation in writing of his own
estimate of the fair value of his shares and the amount of interest due, and
demand payment of his estimate, less any payment pursuant to NRS 92A.460, or
reject the offer pursuant to NRS 92A.470 and demand payment of the fair value of
his shares and interest due, if he believes that the amount paid pursuant to NRS
92A.460 or offered pursuant to NRS 92A.470 is less than the fair value of his
shares or that the interest due is incorrectly calculated.

    2. A dissenter waives his right to demand payment pursuant to this section
unless he notifies the subject corporation of his demand in writing within 30
days after the subject corporation made or offered payment for his shares.

    NRS 92A.490 Legal proceeding to determine fair value: Duties of subject
corporation; powers of court; rights of dissenter.

    1. If a demand for payment remains unsettled, the subject corporation shall
commence a proceeding within 60 days after receiving the demand and petition the
court to determine the fair value of the shares and accrued interest. If the
subject corporation does not commence the proceeding within the 60-day period,
it shall pay each dissenter whose demand remains unsettled the amount demanded.

    2. A subject corporation shall commence the proceeding in the district court
of the county where its registered office is located. If the subject corporation
is a foreign entity without a resident agent in the state, it shall commence the
proceeding in the county where the registered office of the domestic corporation
merged with or whose shares were acquired by the foreign entity was located.

    3. The subject corporation shall make all dissenters, whether or not
residents of Nevada, whose demands remain unsettled, parties to the proceeding
as in an action against their shares. All parties must be served with a copy of
the petition. Nonresidents may be served by registered or certified mail or by
publication as provided by law.

    4. The jurisdiction of the court in which the proceeding is commenced under
subsection 2 is plenary and exclusive. The court may appoint one or more persons
as appraisers to receive evidence and recommend a decision on the question of
fair value. The appraisers have the powers described in the order appointing
them, or any amendment thereto. The dissenters are entitled to the same
discovery rights as parties in other civil proceedings.

    5. Each dissenter who is made a party to the proceeding is entitled to a
judgment:

        (a) For the amount, if any, by which the court finds the fair value of
    his shares, plus interest, exceeds the amount paid by the subject
    corporation; or

        (b) For the fair value, plus accrued interest, of his after-acquired
    shares for which the subject corporation elected to withhold payment
    pursuant to NRS 92A.470.

    NRS 92A.500 Legal proceeding to determine fair value: Assessment of costs
and fees.

    1. The court in a proceeding to determine fair value shall determine all of
the costs of the proceeding, including the reasonable compensation and expenses
of any appraisers appointed by

                                      C-5


the court. The court shall assess the costs against the subject corporation,
except that the court may assess costs against all or some of the dissenters, in
amounts the court finds equitable, to the extent the court finds the dissenters
acted arbitrarily, vexatiously or not in good faith in demanding payment.

    2. The court may also assess the fees and expenses of the counsel and
experts for the respective parties, in amounts the court finds equitable:

        (a) Against the subject corporation and in favor of all dissenters if
    the court finds the subject corporation did not substantially comply with
    the requirements of NRS 92A.300 to 92A.500, inclusive; or

        (b) Against either the subject corporation or a dissenter in favor of
    any other party, if the court finds that the party against whom the fees and
    expenses are assessed acted arbitrarily, vexatiously or not in good faith
    with respect to the rights provided by NRS 92A.300 to 92A.500, inclusive.

    3. If the court finds that the services of counsel for any dissenter were of
substantial benefit to other dissenters similarly situated, and that the fees
for those services should not be assessed against the subject corporation, the
court may award to those counsel reasonable fees to be paid out of the amounts
awarded to the dissenters who were benefited.

    4. In a proceeding commenced pursuant to NRS 92A.460, the court may assess
the costs against the subject corporation, except that the court may assess
costs against all or some of the dissenters who are parties to the proceeding,
in amounts the court finds equitable, to the extent the court finds that such
parties did not act in good faith in instituting the proceeding.

    5. This section does not preclude any party in a proceeding commenced
pursuant to NRS 92A.460 or 92A.490 from applying the provisions of N.R.C.P. 68
or NRS 17.115.
