An alteration of an instrument which destroys the identity of the instrument or of the contract evidenced thereby, or which so changes its terms as to give it different legal effect from that which it originally had, and thus works some change in the rights, obligations, interest, or relations of the party. 4 Am J2d Alt Inst § 5.
