The officers of an association formed under this article shall consist of a president, one or more vice-presidents as may be prescribed by the bylaws, a secretary, and a treasurer, each of whom shall be elected by the board of directors at such time and in such manner as may be prescribed by the bylaws, and none of whom are required to be directors of such association unless the bylaws so provide. The bylaws may provide that any of such officers may not be directors of such an association. The bylaws may provide for the election by the board of directors, from among their number, of a chair of the board of directors and one or more vice-chairs. Such other officers and assistant officers and agents as are necessary may be elected or appointed by the board of directors or chosen in such manner as may be prescribed by the bylaws. The board may combine the offices of secretary and treasurer and designate the combined office as secretary-treasurer, or unite both functions and titles in one person. The treasurer may be a bank or any depository, and, as such, shall not be considered as an officer but as a function of the board of directors. In such case, the secretary shall perform the usual accounting duties of the treasurer; except that the funds shall be deposited only as authorized by the board of directors. All officers and agents of the association, as between themselves and the association, shall have such authority and perform such duties in the management of the association as may be provided in the bylaws, or as may be determined by resolution of the board of directors not inconsistent with the bylaws.
