Mass. Gen. Laws ch. 156B § 65
A director, officer or incorporator of a corporation shall perform his duties as such, including, in the case of a director, his duties as a member of a committee of the board upon which he may serve, in good faith and in a manner he reasonably believes to be in the best interests of the corporation, and with such care as an ordinarily prudent person in a like position would use under similar circumstances. In determining what he reasonably believes to be in the best interests of the corporation, a director may consider the interests of the corporation's employees, suppliers, creditors and customers, the economy of the state, region and nation, community and societal considerations, and the long-term and short-term interests of the corporation and its stockholders, including the possibility that these interests may be best served by the continued independence of the corporation. In performing his duties, a director, officer or incorporator shall be entitled to rely on information, opinions, reports or records, including financial statements, books of account and other financial records, in each case presented by or prepared by or under the supervision of (1) one or more officers or employees of the corporation whom the director, officer or incorporator reasonably believes to be reliable and competent in the matters presented, or (2) counsel, public accountants or other persons as to matters which the director, officer or incorporator reasonably believes to be within such person's professional or expert competence, or (3) in the case of a director, a duly constituted committee of the board upon which he does not serve, as to matters within its delegated authority, which committee the director reasonably believes to merit confidence, but he shall not be considered to be acting in good faith if he has knowledge concerning the matter in question that would cause such reliance to be unwarranted. The fact that a director, officer or incorporator so performed his duties shall be a complete defense to any claim asserted against him, whether under sections sixty to sixty-four, inclusive, or otherwise, expect as expressly provided by statute, by reason of his being or having been a director, officer or incorporator of the corporation.
