(1) Directors' action respecting a transaction is effective for purposes of RCW 23B.08.710(2)(a) if the transaction received the affirmative vote of a majority, but no fewer than two, of those qualified directors on the board of directors or on a duly empowered committee of the board who voted on the transaction after either required disclosure to them, to the extent the information was not known by them, or compliance with subsection (2) of this section, provided that action by a committee is so effective only if:

(a) All its members are qualified directors; and

(b) Its members are either all the qualified directors on the board or are appointed by the affirmative vote of a majority of the qualified directors on the board.

(2) If a director has a conflicting interest respecting a transaction, but neither the director nor a related person of the director specified in RCW 23B.08.700(3)(a) (i) and (ii) is a party to the transaction, and if the director has a duty under law or professional canon, or a duty of confidentiality to another person, respecting information relating to the transaction such that the director may not make the disclosure described in RCW 23B.08.700(4)(b), then disclosure is sufficient for purposes of subsection (1) of this section if the director (a) discloses to the directors voting on the transaction the existence and nature of the director's conflicting interest and informs them of the character and limitations imposed by that duty before their vote on the transaction, and (b) plays no part, directly or indirectly, in their deliberations or vote.

(3) A majority, but no fewer than two, of all the qualified directors on the board of directors, or on the committee, constitutes a quorum for purposes of action that complies with this section. Directors' action that otherwise complies with this section is not affected by the presence or vote of a director who is not a qualified director.
