                           INCOMPLETE INSTRUMENT
                                      
   (a) "Incomplete instrument" means a signed writing, whether or not
   issued by the signer, the contents of which show at the time of
   signing that it is incomplete but that the signer intended it to be
   completed by the addition of words or numbers.
   
   (b) Subject to subsection (c) of this section, if an incomplete
   instrument is an instrument under Section 3-104 of this title, it may
   be enforced according to its terms if it is not completed, or
   according to its terms as augmented by completion. If an incomplete
   instrument is not an instrument under Section 3-104 of this title,
   but, after completion, the requirements of Section 3-104 of this
   title, are met, the instrument may be enforced according to its terms
   as augmented by completion.
   
   (c) If words or numbers are added to an incomplete instrument without
   authority of the signer, there is an alteration of the incomplete
   instrument under Section 3-407 of this title.
   
   (d) The burden of establishing that words or numbers were added to an
   incomplete instrument without authority of the signer is on the person
   asserting the lack of authority.
