(2) before the child's birth, he married or attempted to marry the mother by a marriage solemnized in apparent compliance with law, although the attempted marriage is or could be declared invalid, and the child was born during the attempted marriage or within three hundred days after its termination; or
(3) after the child's birth, he married or attempted to marry the mother by a marriage solemnized in apparent compliance with law, although the attempted marriage is or could be declared invalid, and
(i) he agreed to support the child under a written voluntary promise, or
