ORS 72.2090¹
Modification, rescission and waiver

(1) An agreement modifying a contract within this chapter needs no consideration to be binding.

(2) A signed agreement which excludes modification or rescission except by a signed writing cannot be otherwise modified or rescinded, but except as between merchants such a requirement on a form supplied by the merchant must be separately signed by the other party.

(3) The requirements of ORS 72.2010 (Formal requirements: statute of frauds), relating to the statute of frauds must be satisfied if the contract as modified is within its provisions.

(4) Although an attempt at modification or rescission does not satisfy the requirements of subsection (2) or (3) of this section, it can operate as a waiver.

(5) A party who has made a waiver affecting an executory portion of the contract may retract the waiver by reasonable notification received by the other party that strict performance will be required of any term waived, unless the retraction would be unjust in view of a material change of position in reliance on the waiver. [1961 c.726 §72.2090 (Modification, rescission and waiver)]
