Quorum for meetings of members

The quorum for a meeting of members for purposes of a resolution of members is that fixed by the Memorandum or Articles; but, where no quorum is so fixed a meeting of members is properly constituted for all purposes if at the commencement of the meeting there are present in person or by proxy one-half of the votes of the shares of each class or series thereon and the same proportion of the votes of the remaining shares entitled to vote thereon.
