§12A-8-307.
   
   Purchaser's Right to Requisites for Registration of Transfer.
   
   Unless otherwise agreed, the transferor of a security on due demand
   shall supply the purchaser with proof of authority to transfer or with
   any other requisite necessary to obtain registration of the transfer
   of the security, but if the transfer is not for value, a transferor
   need not comply unless the purchaser pays the necessary expenses. If
   the transferor fails within a reasonable time to comply with the
   demand, the purchaser may reject or rescind the transfer.
