Dear Shareholder:

We have previously sent to you proxy material for the Special Meeting of Leucadia National Corporation shareholders, to be held on February 28, 2013 to allow shareholders to vote on four proposals relating to our proposed merger with Jefferies Group, Inc.

You are being asked to vote on: (1) a proposal to approve the issuance of Leucadia common shares to stockholders of Jefferies to be issued as the merger consideration in connection with the proposed merger with Jefferies; (2) a proposal to approve an amendment to the transfer restrictions already contained in Leucadia’s certificate of incorporation to prevent any person from becoming a “5% shareholder” or being treated as owning more than 5% of the Leucadia common shares for purposes of Section 382 of the Internal Revenue Code of 1986, as amended; (3) an advisory (non-binding) vote on the compensation that may be paid or become payable to Leucadia’s named executive officers that is based on or otherwise related to the proposed transactions; and (4) a proposal to adjourn the Leucadia special meeting, if necessary, to solicit additional proxies if there are not sufficient votes at the time of the special meeting.

Your Board of Directors unanimously recommends that shareholders vote FOR each of the proposals.

Approval of proposal 2 requires the affirmative vote of a majority of the outstanding shares. Therefore your vote is important, no matter how many or how few shares you may own.  If you have not already done so, please vote TODAY by telephone, via the Internet, or by signing, dating and returning the enclosed proxy card in the envelope provided.

Very truly yours,

Laura E. Ulbrandt
