(iv) use reasonable best efforts to cause the Holder Designees to comprise a majority of Directors of the Board at or prior to the Meeting;

(vi) not adopt or propose any management incentive plan or make any grants of stock, options or other compensation under any management incentive plan until such time as all of the appointments and other actions set forth in subclauses (i) and (ii) above shall have been effectuated; provided, however, that any management incentive plan thereafter approved and implemented by the Company shall be consistent in all respects with the terms set forth in the Restructuring Term Sheet;

(vii) if any Holder Designee is not elected to the Board at or prior to the Meeting, then the Holder Designees who have been so elected as Directors shall nominate and elect one or more candidates as necessary for the Holder Designees elected pursuant to this subclause (vii), together with the Holder Designees elected pursuant to subclauses (i) and (ii) above, to constitute a majority of Directors of the Board; and

(viii) in the event the Board is unable to agree on the four existing Directors (excluding Holder Designees) to remain on the Board following the Effective Date, the Company shall use its reasonable best efforts to cause the terms of the existing Directors in a class with the longest term expiry to terminate, it being understood, however that this clause (viii) shall not apply to the chairman of the Board in office as of the Effective Date.
