Okla. Stat. tit. 18, § 18-441-815: Quorum

QUORUM.

(a) Unless the articles of organization provide for a greater

number, a majority of the total number of directors specified by the

organic rules constitutes a quorum for a meeting of the directors.

(b) If a quorum of the board of directors is present at the

beginning of a meeting, any action taken by the directors present is

valid even if withdrawal of directors originally present results in

the number of directors being fewer than the number required for a

quorum.

(c) A director present at a meeting but objecting to notice

under paragraph (1) or (2) of subsection (b) of Section 79 of this

act does not count toward a quorum.
