Except as otherwise expressly provided for herein, the Members hereby consent to the exercise by the Board of all such powers and rights conferred on them by the Act or otherwise by law with respect to the management and control of the Company. No Member and no Representative, in its capacity as such, shall have any power to act for, sign for, or do any act that would bind the Company.

     B. Board of Representatives. (a) Initial Board. The Board shall initially consist of the following three individuals:

The Chairman of the initial Board shall be ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇▇. The Chairman, if appointed, shall preside over meetings of the Board and shall otherwise have no greater authority than any other Representative. In the absence of the Chairman, any one of the other Representatives shall preside at all meetings of the Board. Such Representative shall have duties customarily performed by a “lead director” or “presiding director” and shall otherwise have no greater authority than any other Representative.

          (c) Voting. Each Representative, including the Chairman, shall have a single vote. Except as otherwise required by Law, the affirmative vote of a majority of the Representatives in attendance at any meeting at which a quorum is present in accordance with Section 7C(c) shall be required to authorize any action. Any vote, consent or other action of the Board may be undertaken with the unanimous written consent (in lieu of meeting) of the Representatives, in each case who have been appointed and who are then in office.

          (d) Proxies. Any Representative may vote at a meeting of the Board or any committee thereof either in person or by proxy executed in writing by such Representative. A telegram, telex, cablegram or similar transmission by the Representative, or a photographic, photostatic, facsimile or similar reproduction of a writing executed by the Representative shall (if stated thereon) be treated as a proxy executed in writing for purposes of this Section 7B(d). Proxies for use at any meeting of the Board or any committee thereof or in connection with the taking of any action by written consent shall be filed with the Board, before or at the time of the meeting or

execution of the written consent, as the case may be. No proxy shall be valid after eleven months from the date of its execution unless otherwise provided in the proxy. A proxy shall be revocable unless the proxy form conspicuously states that the proxy is irrevocable and the proxy is coupled with an interest.

     C. Meetings of the Board.

          (a) Meetings. The Board shall meet at such times and at such places as the Board may designate. Special meetings of the Board shall be held at the request of any Representative upon at least two business days’ written notice to all of the Representatives, or upon such shorter notice as may be approved by all of the Representatives; provided that if the nature of the action to be taken is such that time is of the essence with respect to such action, such meeting may be held without such two business days’ notice if at least one business day’s notice has been given and (A) a good faith effort has been made to notify and consult with each of the Representatives entitled to vote on such action and (B) a quorum exists for the taking of such action. Any Representative may waive the requirement of such notice as to itself, before, at or after the meeting.

          (b) Conduct of Meetings. Any meeting of the Board may be held in person, telephonically or through other communications equipment by means of which all participating members of the Board can simultaneously hear each other during the meeting.

          (c) Quorum. A majority of the Representatives who have been appointed pursuant to the provisions of this Agreement and who are then in office shall be necessary to constitute a quorum of the Board for purposes of conducting business.

          (d) Payments to Representatives; Reimbursements. All Representatives will be entitled to reimbursement of their reasonable out-of-pocket expenses incurred in connection with their attendance at Board meetings and such reasonable and customary fees as may be authorized by the Board.

          (e) Board Committees. The Board may organize such committees of the Board as it deems reasonably necessary to effectively govern the Company.

     D. Member Action. Any action of the Members shall be authorized if the affirmative vote of the holders of a majority of the membership interests present at a meeting at which a quorum is present shall be obtained. Any action which may be taken by the Members under this Agreement shall be authorized if consents in writing setting forth the action so taken are signed by Members who hold a majority of the membership interests then outstanding. Any Member who does not participate in taking the action by written consent shall be given written notice thereof by the Secretary of the Company after such action has been taken. The presence in person or by proxy of the holders of a majority of the outstanding membership interests shall be necessary to constitute a quorum for action by the Members. Whenever the giving of any notice to Members is required by law or this Agreement, a waiver thereof, in writing and delivered to the

Company signed by the person or persons entitled to said notice, whether before or after the event as to which such notice is required, shall be deemed equivalent to notice. Attendance of a Member at a meeting or execution of a written consent to any action shall constitute a waiver of notice of such meeting or action.

     E. Officers. (a) Designation and Appointment. The Board may, from time to time, employ and retain persons as may be necessary or appropriate for the conduct of the Company’s business (subject to the supervision and control of the Board), including employees, agents and other Persons (any of whom may be a Member or Representative) who may be designated as Officers of the Company, with titles including but not limited to “chief executive officer,” “president,” “vice chairman,” vice president,” “treasurer,” “secretary,” “general counsel,” “director,” “chief financial officer” and “chief operating officer” as and to the extent authorized by the Board.

Any Officer may be removed as such, either with or without cause, at any time by the Board. Designation of any Person as an Officer by the Board shall not in and of itself vest in such Person any contractual or employment rights with respect to the Company.
