On September 2, 2011, Leucadia and the Company entered into a two year standstill agreement (the “Standstill Agreement”) providing for, among other matters, a cap of 27.5% ownership for the Reporting Persons (subject to certain provisions), representation for Leucadia on the Board (with Leucadia having the right to designate two of the Company’s directors, subject to reduction in certain circumstances, and the Company agreeing not to increase the size of the board above ten directorships without the consent of both Leucadia’s designees to the Board and a majority of the Board unaffiliated with Leucadia), Leucadia’s agreement to vote for the Board’s director nominees, certain restrictions on proposals that may be made by the Reporting Persons (including as to the composition of the Board) without approval of the Board, Leucadia’s agreement not to sell to any person or group who holds, or after giving effect to a sale would hold, in excess of 4.9% of the Company’s common stock and the Company’s agreement to enter into a registration rights agreement covering all shares of the Company’s common stock owned by Leucadia, all on the terms and conditions set forth in the Standstill Agreement. The Standstill Agreement will terminate early if the Reporting Persons own less than 5% of the Common Stock for 90 days and upon the happening of certain other events.  The Standstill Agreement is attached hereto as Exhibit 1 and is incorporated in its entirety herein by reference.

Pursuant to the Standstill Agreement, on September 2, 2011, the Company filed a Current Report on Form 8-K with the Securities and Exchange Commission announcing, among other things, that the Board had created two new director positions and elected Ian M.
