The business of a cooperative shall be managed by a board of not less than five directors, each of whom shall be a member of the cooperative or of another cooperative which is a member of it. The bylaws shall prescribe the number of directors, their qualifications other than those prescribed in this chapter, and the manner of holding meetings of the board of directors and of electing successors to directors who resign, die, or are otherwise incapable of acting. The bylaws shall provide for the removal of directors from office for cause and for the election of their successors. Directors may not receive salaries for the services as directors and, except in emergencies, may not receive salaries for their services in any other capacity without the approval of the members. The bylaws may, however, prescribe a fixed fee for each day of attendance at a meeting of the board of directors or other meeting while officially representing the cooperative and for each day of necessary travel to and from a meeting of the board of directors or other meeting while officially representing the cooperative and may provide for insurance and reimbursement of actual expenses incurred while performing duties as a director.
