an incomplete instrument, by completing it otherwise than as authorized; or

(c)

the writing as signed, by adding to it or by removing any part of it.

As against any person other than a subsequent holder in due course (a) alteration by the holder which is both fraudulent and material discharges any party whose contract is thereby changed unless that party assents or is precluded from asserting the defense;

(b)

no other alteration discharges any party and the instrument may be enforced according to its original tenor, or as to incomplete instruments according to the authority given.
