a manager-managed entity, the members of the Executive Committee of Buyer will serve as the managers of Val-E, and each of the then current managers of Val-E will serve on the initial Board of Managers of Val-E, which Board of Managers will be a
local board similar in nature and function to the local boards of other Buyer subsidiaries.
