(a) Unless the articles of incorporation or bylaws provide otherwise, action required or permitted by this chapter to be taken at a board of directors' meeting may be taken without a meeting if the action is taken by all members of the board. The action must be evidenced by one or more written consents describing the action taken, signed by each director, and delivered to the corporation for inclusion in the minutes or filing with the corporate records.

(b) A consent signed under this Code section has the effect of a meeting vote and may be described as such in any document.
