(1) A majority of the fixed number of directors if the corporation has a fixed-board size; or
(2) A majority of the number of directors prescribed, or if no number is prescribed, the number in office immediately before the meeting begins if the corporation has a variable-range size board.
(b) The articles of incorporation or bylaws may authorize a quorum of a board of directors to consist of no fewer than one third of the fixed or prescribed number of directors determined under subsection (a) of this section.

(d) A director who is present at a meeting of the board of directors or a committee of the board of directors when corporate action is taken is deemed to have assented to the action taken unless: (1) He or she objects at the beginning of the meeting or promptly upon his or her arrival to holding it or transacting business at the meeting; (2) his or her dissent or abstention from the action taken is entered in the minutes of the meeting; or (3) he or she delivers written notice of his or her dissent or abstention to the presiding officer of the meeting before its adjournment.
