Notice in the form of a record setting forth the proposed plan or a summary thereof shall be given to each member entitled to vote at such meeting within the time and in the manner provided in this chapter for the giving of notice of meetings of members. The proposed plan shall be adopted upon receiving at least two-thirds of the votes which members present at each such meeting or represented by proxy are entitled to cast.
