(a) Except to the extent that the certificate of incorporation or bylaws require that action by the board of directors be taken at a meeting, action required or permitted by this chapter to be taken by the board of directors may be taken without a meeting if each director signs a consent describing the action to be taken and delivers it to the corporation.
(b) Action taken under this section is the act of the board of directors when one or more consents signed by all the directors are delivered to the corporation. Any director executing a consent may provide, whether through instruction to an agent or otherwise, that such consent will be effective at a future time, including a time determined upon the happening of an event, occurring not later than 60 days after such instruction is given or such provision is made, if evidence of the instruction or provision is provided to the corporation. A director’s consent may be withdrawn by a revocation signed by the director and delivered to the corporation before delivery to the corporation of unrevoked written consents signed by all the directors.
(c) A consent signed under this section has the effect of action taken at a meeting of the board of directors and may be described as such in any document.
