As to any matter disposed of by settlement by any such person, pursuant to a consent decree or otherwise, no such indemnification either for the amount of such settlement or for any other expenses shall be provided unless such settlement shall be approved as in the best interests of the corporation, after notice that it involves such indemnification, (a) by a vote of a majority of the disinterested directors then in office (even though the disinterested directors be less than a quorum), or (b) by any disinterested person or persons to whom the question may be referred by vote of a majority of such disinterested directors, or (c) by vote of the holders of a majority of the outstanding stock at the time entitled to vote for directors, voting as a single class, exclusive of any stock owned by any interested persons, or (d) by any disinterested person or persons to whom the question may be referred by vote of the holders of a majority of such stock. No such approval shall prevent the recovery from any such officer, director, employee, agent or trustee of any amounts paid to him or on his behalf as indemnification in accordance with the preceding sentence if such person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that his action was in the best interests of the corporation.
