(a) If the certificate of incorporation or the by-laws provide that a
member shall be of full age:
(1) A corporation may treat an infant who holds a membership
certificate or card or capital certificate or a bond of such corporation
as having capacity to receive and to empower others to receive payments
or distributions, to vote or express consent or dissent, in person or by
proxy, and to make elections and exercise rights relating to such
certificates or bonds, unless, in the case of membership certificates or
cards or capital certificates, the corporate officer responsible for
maintaining the list or record of members or the transfer agent of the
corporation or, in the case of bonds, the treasurer or paying officer or
agent has received written notice that such holder is an infant.
(2) An infant holder of a membership certificate or card or capital
certificate or a bond of a corporation who has received or empowered
others to receive payments or distributions, voted or expressed consent
or dissent, or made an election or exercised a right relating thereto,
shall have no right thereafter to disaffirm or avoid, as against the
corporation, any such act on his part, unless prior to such receipt,
vote, consent, dissent, election or exercise, as to membership
certificates or cards or capital certificates, the corporate officer
responsible for maintaining the list or record of members or its
transfer agent or, in the case of bonds, the treasurer or paying officer
or agent had received written notice that such holder was an infant.
