(a) A director who votes for or assents to a distribution made in violation of Section 33-6-400 or the articles of incorporation is personally liable to the corporation for the amount of the distribution that exceeds what could have been distributed without violating Section 33-6-400 or the articles of incorporation if it is established that he did not perform his duties in compliance with Section 33-8-300. In any proceeding commenced under this section, a director has all of the defenses ordinarily available to a director.
(b) A director held liable under subsection (a) for an unlawful distribution is entitled to contribution:
(1) from every other director who could be held liable under subsection (a) for the unlawful distribution; and
(2) from each shareholder for the amount the shareholder accepted knowing the distribution was made in violation of Section 33-6-400 or the articles of incorporation.
