A restriction on transfer of a security imposed by the issuer, even if otherwise lawful, is ineffective against any person without actual knowledge of the restriction unless: 1. The security is certificated and the restriction is noted conspicuously on the security certificate; or 2. The security is uncertificated and the registered owner has been notified of the restriction. (Added to NRS by 1965, 880; A 1985, 92; 1997, 393)
