(a) A member of a board shall avoid the appearance of conflict of interest by not voting in, or participating in, any decision by the board regarding the provision of services by such member, or any organization which that member directly represents, or on any matter which would provide direct financial benefit to that member, the member's immediate family, or any organization which that member directly represents.
(b) Subsection (a) shall serve as a minimum standard and shall not be construed as to limit the board's authority for more restrictive governance to prevent real and/or apparent conflict of interest.
