10. Neither the chairman nor the vice-chairman may, under pain of forfeiture of office, have any direct or indirect interest in an undertaking causing his personal interest to conflict with that of the board. However, such forfeiture is not incurred if such an interest devolves to him by succession or gift, provided that he renounces or disposes of it with all possible dispatch.
Every other commissioner having a direct or indirect interest in an undertaking causing his personal interest to conflict with that of the board must, under pain of forfeiture of office, divulge this interest in writing to the chairman of the board and abstain from taking part in any discussion or decision regarding that undertaking.
