Entire Agreement

The Entire Agreement or Integration clause defines what is and is not a part of the agreement. It codifies the parol evidence rule, which simply stated provides that "the final agreement made by the parties supercedes any terms discussed in earlier negotiations."

Standard and Alternative Language

  2. Agreement Supersedes Trade Language

    Entire Agreement. This Agreement, together with the exhibits and schedules hereto, constitutes the entire understanding and agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior and contemporaneous agreements or understandings, inducements or conditions, express or implied, written or oral, between the parties with respect hereto other than the Confidentiality Agreement. The express terms hereof control and supersede any course of performance or usage of the trade inconsistent with any of the terms hereof.

Peter Linzer writes that "the parol evidence rule fits none of the words in its name: it is not limited to parol--that is, oral--testimony, it is not evidentiary, and is not really a rule.

The challenge for contract drafting is that language is never perfectly clear and unambiguous. Frequently, it must be "interpreted", sometimes beyond the four corners of the document, creating a continuum from strict interpretation (Williston) to more liberal guides (Corbin, The Restatement of Contracts Second, ). For example, UCC § 2‐202 provides exceptions for course of dealing or custom:

  • UCC § 2‐202. 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
  • (a) by course of dealing or usage of trade (Section 1‐205) or by course of performance (Section 2‐208); and
  • (b) 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.
