(b) During an emergency defined in subsection (d), unless emergency bylaws provide otherwise: (1) Notice of a meeting of the board of directors need be given only to those directors whom it is practicable to reach and may be given in any practicable manner, including by publication and radio. (2) One or more officers of the corporation present at a meeting of the board of directors may be considered to be directors for the meeting, in order of rank and within the same rank in order of seniority, as necessary to achieve a quorum. (c) Corporate action taken in good faith during an emergency under this section to further the ordinary business affairs of the corporation: (1) binds the corporation; and (2) may not be used to impose liability on a corporate director, officer, employee, or agent. (d) An emergency exists for purposes of this section if a quorum of the corporation's directors cannot be assembled readily because of some catastrophic event.
