     § 2A202.  Final written expression: parol or extrinsic evidence.
        Terms with respect to which the confirmatory memoranda of the
     parties agree or which are otherwise set forth in a writing
     intended by the parties as a final expression of their agreement
     with respect to such terms as are included therein may not be
     contradicted by evidence of any prior agreement or of a
     contemporaneous oral agreement but may be explained or
     supplemented:
            (1)  by course of dealing or usage of trade or by course
        of performance; and
            (2)  by evidence of consistent additional terms unless
        the court finds the writing to have been intended also as a
        complete and exclusive statement of the terms of the
        agreement.
