(1) When contract or transaction is not void or voidable. No contract or other transaction between a corporation and a director, or any entity in which a director is a director or officer or has a material financial interest, is void or voidable because of the relationship or interest or because the director is present at the meeting of the board or a committee that authorizes, approves or ratifies the contract or transaction or because the director’s vote is counted for that purpose, if any of the following applies:
(a) The relationship or interest is disclosed or known to the board or committee that authorizes, approves or ratifies the contract or transaction and the contract or transaction was authorized, approved or ratified by a vote or consent sufficient for the purpose without counting the votes or consents of interested directors.
(b) The fact of such relationship or interest is disclosed or known to the members entitled to vote and they authorize, approve or ratify that contract or transaction by vote or written consent.
(c) The contract or transaction is fair and reasonable to the corporation.
(2) Quorum requirements. Common and interested directors may be counted in determining the presence of a quorum at a meeting of the board or a committee that authorizes, approves or ratifies a contract or transaction under sub. (1).
(3) Additional requirements. The articles of incorporation, the bylaws or a resolution of the board may impose additional requirements on conflict of interest transactions.
