“The Agreement sets forth the entire Agreement between the Parties regarding the subject matters covered herein and supersedes any and all prior oral and written communications between the Parties, …. Any amendments to this Agreement must be in writing and signed by the Parties”
“A term which would otherwise be implied as a result of custom or usage may be excluded by an “entire agreement” clause. But a conventional “entire contract” clause does not affect the question whether some matter of fact (whether or not in documentary form) is admissible as an aid to the process of construing a contractual document. On this basis it is considered that an entire agreement clause would not usually preclude the implication of a term because the implication of a term is elucidating what the written contract means.”
