4-3-402.    Signature by representative.
    (a)  If  a person acting, or purporting to act, as a representative signs an  instrument by signing either the name of the represented person or the  name of the signer, the represented person is bound by the signature to  the same extent the represented person would be bound if the signature  were on a simple contract. If the represented person is bound, the  signature of the representative is the "authorized signature of the  represented person" and the represented person is liable on the  instrument, whether or not identified in the instrument.
(b)  If  a representative signs the name of the representative to an instrument  and the signature is an authorized signature of the represented person,  the following rules apply:
      (1)  If  the form of the signature shows unambiguously that the signature is  made on behalf of the represented person who is identified in the  instrument, the representative is not liable on the instrument.
      (2)  Subject  to subsection (c), if (i) the form of the signature does not show  unambiguously that the signature is made in a representative capacity or  (ii) the represented person is not identified in the instrument, the  representative is liable on the instrument to a holder in due course  that took the instrument without notice that the representative was not  intended to be liable on the instrument. With respect to any other  person, the representative is liable on the instrument unless the  representative proves that the original parties did not intend the  representative to be liable on the instrument.
(c)  If  a representative signs the name of the representative as drawer of a  check without indication of the representative status and the check is  payable from an account of the represented person who is identified on  the check, the signer is not liable on the check if the signature is an  authorized signature of the represented person.
