ARTICLE IV

The Board of Directors and Committees

4.1.          Election of MMI Director.  Promptly after the date hereof, the Company shall cause (A) the total number of members of the Board to be increased by one member over the number authorized as of the date of such notice, and (B) the vacancy so created to be filled with one individual designated by MMI and approved by a majority of the Directors, which approval may not be unreasonably withheld (the “MMI Director”).  The initial MMI Director shall be Clay Lifflander.  Thereafter, with respect to each annual meeting of shareholders of the Company until the earlier of (i) the expiration of the Standstill Period, and (ii) the date on which MMI Beneficially owns less than ten percent (10%) of the outstanding Common Shares (the “Specified Equity Percentage”), unless the MMI Director resigns or is removed pursuant to Section 4.3, the Company shall use its reasonable best efforts to cause its Directors to solicit proxies for, and recommend that the Company’s shareholders vote in favor of, the MMI Director.

4.2.          Replacement Notice for MMI Director.  In the event that the MMI Director (a “Withdrawing MMI Director”) designated in the manner set forth in Section 4.1 is unable to serve, or once having commenced to serve, is removed or withdraws from the Board, MMI shall promptly after such MMI Director ceases to be a member of the Board but in no event later than 5 days of such removal or withdrawal provide notice to the Company if it intends to replace  such Withdrawing MMI Director (the “Substitute MMI Director”) pursuant to this Section 4.2 (the “Replacement Notice”); provided, however that nothing herein shall limit a removal or withdrawal pursuant to Section 4.3.  The Substitute MMI Director will be designated by MMI in consultation with the Board and subject to the Board nomination process.  The Company shall promptly, upon the request of MMI, use its reasonable best efforts to cause the election or appointment of such Substitute MMI Director (who will be any person approved by a majority of the Directors, which approval may not be unreasonably withheld) to replace the Withdrawing MMI Director.  Following such election or appointment, the Substitute MMI Director shall become the MMI Director.  The right to designate a Director pursuant to this Section 4.2 is personal to MMI and may not be transferred in any manner except to a wholly owned Affiliate of MMI.  Notwithstanding anything in this Agreement to the contrary, the MMI Director is permitted to resign or otherwise withdraw from, or cease to serve on, the Board at any time in his

4

sole discretion and if he resigns, otherwise withdraws from, or ceases to serve on, the Board, and no Replacement Notice is given, the Standstill Period and this Agreement shall terminate three months following such resignation, withdrawal or cessation.

4.3.          Resignation of MMI Director.  Upon expiration of the Standstill Period or in the event that MMI Beneficially owns less than the Specified Equity Percentage at any time during the Standstill Period or in the event MMI challenges the validity of, or is in material non-compliance with any of the terms of, this Agreement, the Board may at such time request the MMI Director to resign from the Board, and within five (5) calendar days following such request, the MMI Director shall resign from the Board.  The Company’s Certificate of Incorporation or by-laws may provide that in the event that MMI and its Affiliates Beneficially own less than the Specified Equity Percentage or in the event MMI challenges the validity of, or is in material non-compliance with any of the terms of this Agreement, the Board may vote to remove the MMI Director without necessity of any action whatsoever on the part of the MMI Director or MMI, which removal shall be immediately effective.

4.4.          Compliance.  The MMI Director shall comply with the charter and by-laws or other organizational documents of the Company, the Board’s policies and procedures including, without limitation, its corporate governance guidelines, and all other requirements applicable to the Company’s Board members as in effect from time to time.  The Company shall provide copies of these documents and written guidance to the MMI Director to ensure compliance.  Following a failure to comply with the foregoing, the Board may at such time request the MMI Director to resign from the Board, and within five (5) calendar days following such request, the MMI Director shall resign from the Board.  The Company’s Certificate of Incorporation or by-laws may provide that in such event, the Board may vote to remove the MMI Director without necessity of any action whatsoever on the part of the MMI Director or MMI, which removal shall be immediately effective.

4.5.          Committees.  The Company shall use reasonable best efforts to cause the election of  the MMI Director to serve on the nominating committee (or other similar committee performing the functions typically performed by the nominating committee) subject at all applicable times to such MMI Director being “independent” in accordance with all applicable listing organization requirements and provided that such MMI Director shall comply with the nominating committee’s governance requirements, charter, policies, procedures and all other requirements applicable to nominating committee’s members.  During the Standstill Period, the Company shall not create an executive or other special committee of the Board with authority to act on behalf of the Company or the Board without the consent of the MMI Director; provided, however, that such consent shall not be required if, upon the advice of Company outside counsel, the MMI Director would not be eligible to serve on such committee as a result of a potential conflict of interest, lack of independence or other legal or fiduciary limitation; provided further that should the MMI Director, after consultation with outside counsel, determine in good faith that he is eligible to serve on such committee, he may resign from the Board and the Standstill Period shall terminate forthwith (without the three month tail period set forth in the definition of the Standstill Period).  For the avoidance of doubt, nothing herein shall restrict the ability of the Board to form a committee  for the purpose of reviewing any matter and making recommendations to the Board.

5.1.          Board of Directors; Other.  MMI agrees that in exercising its voting rights on the election of directors of the Company or as set forth below, whether at an annual or special meeting of shareholders of the Company whether by written consent, proxy or otherwise, and whether or not at an adjourned meeting, MMI shall vote all its Voting Securities of the Company (a) for the election to the Board of the individuals nominated or designated by the Board (or any nominating or similar committee of the Board), and (b) for any amendment to the Company’s Certificate of Incorporation or by-laws intended to make effective the provision of Sections 4.3 and 4.4 of this Agreement.

5.2.          Quorum.  During the Standstill Period, MMI, as holder of Voting Securities of the Company, shall be present, in person or by proxy, at any meeting of shareholders of the Company for the purpose, among others, if any, to elect directors, so that all such Voting Securities may be counted for the purpose of determining the existence of a quorum at such meeting.
