Title 14, Chapter 2, Section 913
(a) An attempt to transfer shares in a statutory close corporation
in violation of a prohibition against transfer binding on the
transferee is ineffective.
(b) An attempt to transfer shares in a statutory close corporation in violation of a prohibition against transfer that is not binding on the transferee, either because the notice required by Code Section 14-2-910 was not given or because the prohibition is held unenforceable by a court, gives the corporation an option to purchase the shares from the transferee for the same price and on the same terms that he purchased them; provided, however, that in the case of a gift, the purchase shall be at a price and upon terms which are agreed upon by the parties, or if no agreement is reached, then at the fair value of the shares and upon terms as determined by a court in accordance with standards set forth in Code Section 14-2-942. To exercise its option, the corporation must give the transferee written notice within 30 days after they are presented for registration in the transferee's name. The corporation may specifically enforce the transferee's sale obligation upon exercise of its purchase option.
