Final 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 record 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: (a) by course of performance, course of dealing or usage of trade (§ 8.1A-303 ); and (b) by evidence of consistent additional terms unless the court finds the record to have been intended also as a complete and exclusive statement of the terms of the agreement. 1964, c. 219; 2003, c. 353 ; 2024, c. 652 .
