A restriction is not binding with respect to securities issued prior to the adoption of the restriction, unless the holders of those securities are parties to the agreement or voted in favor of the restriction. 2. A written restriction on the transfer or registration of transfer of securities of a corporation which is not manifestly unreasonable under the circumstances and is noted conspicuously on the face or back of the certificate or included in information sent to the holders of uncertificated shares in accordance with subsection 6 of section 10-19.1-66 is valid and specifically enforceable against the holder of the restricted securities or a successor or transferee of the holder, including a pledgee or a legal representative. a.
