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:
