In such case, in addition to the authorization of the exchange by the proportion of votes indicated above of all outstanding shares entitled to vote thereon, the exchange 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 2 of this clause (A) 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.
Notwithstanding shareholder authorization and at any time prior to the filing of the certificate of exchange, the plan of exchange may be abandoned pursuant to a provision for such abandonment, if any, contained in the plan of exchange.
