In addition, each director will continue to be subject 9. to liability for (i) acts or omissions that involve intentional misconduct or a knowing and culpable violation of law, (ii) acts or omissions that a director believes to be contrary to the best interests of the Company or its shareholders or that involve the absence of good faith on the part of the director, (iii) any transaction form which a director derived an improper personal benefit, (iv) acts or omissions that show a reckless disregard for the director's duty to the Company or its shareholders in circumstances in which the director was aware, or should have been aware, in the ordinary course of performing a director's duties, of a risk of serious injury to the Company or its shareholders, (v) acts or omissions that constitute an unexcused pattern of inattention that amounts to an abdication of the director's duty to the Company of its shareholders, (vi) any transaction that constitutes an illegal distribution or dividend under California law, and (vii) any transaction involving an unlawful conflict of interest between the director and the Company under California law. The provision also does not affect a director's responsibilities under any other law, such as the federal securities laws or state or federal environmental laws. 10.
