(a) No contract or other transaction between a corporation and one or more of its directors, or between a corporation and any corporation, firm or association in which one or more of its directors has a material financial interest, is either void or voidable because such director or directors or such other corporation, firm or association are parties or because such director or directors are present at the meeting of the board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if

(1) The material facts as to the transaction and as to such director’s interest are fully disclosed or known to the shareholders and such contract or transaction is approved by the shareholders (Section 153) in good faith, with the shares owned by the interested director or directors not being entitled to vote thereon, or

(2) The material facts as to the transaction and as to such director’s interest are fully disclosed or known to the board or committee, and the board or committee authorizes, approves or ratifies the contract or transaction in good faith by a vote sufficient without counting the vote of the interested director or directors and the contract or transaction is just and reasonable as to the corporation at the time it is authorized, approved or ratified, or

(3) As to contracts or transactions not approved as provided in paragraph (1) or (2) of this subdivision, the person asserting the validity of the contract or transaction sustains the burden of proving that the contract or transaction was just and reasonable as to the corporation at the time it was authorized, approved or ratified. A mere common directorship does not constitute a material financial interest within the meaning of this subdivision. A director is not interested within the meaning of this subdivision in a resolution fixing the compensation of another director as a director, officer or employee of the corporation, notwithstanding the fact that the first director is also receiving compensation from the corporation.

(b) No contract or other transaction between a corporation and any corporation or association of which one or more of its directors are directors is either void or voidable because such director or directors are present at the meeting of the board or a committee thereof which authorizes, approves or ratifies the contract or transaction, if:

(1) The material facts as to the transaction and as to such director’s other directorship are fully disclosed or known to the board or committee, and the board or committee authorizes, approves or ratifies the contract or transaction in good faith by a vote sufficient without counting the vote of the common director or directors or the contract or transaction is approved by the shareholders (Section 153) in good faith, or

(2) As to contracts or transactions not approved as provided in paragraph (1) of this subdivision, the contract or transaction is just and reasonable as to the corporation at the time it is authorized, approved or ratified. This subdivision does not apply to contracts or transactions covered by subdivision (a)

(c) Interested or common directors may be counted in determining the presence of a quorum at a meeting of the board or a committee thereof which authorizes, approves or ratifies a contract or transaction.
