KRS 355.2-202: 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:

(1) By course of performance, course of dealing, or usage of trade ( KRS 355.1-303);

and

(2) 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.
