A company shall not register under Article 629 without the assent of a majority of such of its members as are present in person or by proxy (in cases where proxies are allowed) at a general meeting summoned for the purpose.

Where a company not having the liability of its members limited by a statutory provision or letters patent is about to register as a limited company, the majority required to assent as required by paragraph (1) shall consist of not less than three-fourths of the members present in person or by proxy at the meeting.

In computing any majority under this Article when a poll is demanded, regard is to be had to the number of votes to which each member is entitled according to the company's regulations.

Where a company is about to register (under Article 629) as a company limited by guarantee, the assent to its being so registered shall be accompanied by a resolution declaring that each member undertakes to contribute to the company's assets, in the event of its being wound up, while he is a member, or within one year after he ceases to be a member, for payment of the company's debts and liabilities contracted before he ceased to be a member, and of the costs and expenses of winding up and for the adjustment of the rights of the contributories among themselves, such amount as may be required, not exceeding a specified amount.
