(2) "Indorser" means a person who makes an indorsement.
(3) For the purpose of determining whether the transferee of an instrument is a holder, an indorsement that transfers a security interest in the instrument is effective as an unqualified indorsement of the instrument.
(4) If an instrument is payable to a holder under a name that is not the name of the holder, indorsement may be made by the holder in the name stated in the instrument or in the holder’s name or both, but signature in both names may be required by a person paying or taking the instrument for value or collection.
