If any amendment, alteration, repeal, share exchange, reclassification, merger or consolidation resulting from the consummation of a binding share exchange or reclassification involving the Preferred Stock, or of a merger or consolidation of M&T with or into another corporation or other entity, would adversely affect the Preferred Stock and one or more but not all of our other series preferred stock in substantially the same manner, then only the Preferred Stock and such other series of preferred stock as are adversely affected shall vote on the matter together as a single class in proportion to their respective stated amounts. Without the consent of the holders of the Preferred Stock, so long as such action does not adversely affect the rights, preferences, privileges and voting powers, and limitations and restrictions thereof, of the Preferred Stock, we may amend,
