The Officers shall serve at the pleasure of the Board of Managers, subject to all rights, if any, of an Officer under any contract of employment. Any individual may hold any number of offices.

Officer reasonably believes are within the person’s professional or expert competence. An Officer is not acting in good faith who has knowledge concerning the matter in question that makes reliance otherwise permitted by this provision unwarranted.
