In such case, in addition to the authorization of the merger or consolidation by the requisite number of votes of all outstanding shares entitled to vote thereon pursuant to the first sentence of this subparagraph (2), the merger or consolidation shall be authorized by a majority of the votes of all outstanding shares of the class entitled to vote as a separate class. If any provision referred to in subclause (B) of clause (ii) of this subparagraph would affect the rights of the holders of shares of only one or more series of any class but not the entire class, then only the holders of those series whose rights would be affected shall together be considered a separate class for purposes of this section.
