(1) Where the contract for sale involves repeated occasions for performance by either party with knowledge of the nature of the performance and opportunity for objection to it by the other, any course of performance accepted or acquiesced in without objection shall be relevant to determine the meaning of the agreement.

(2) The express terms of the agreement and any such course of performance, as well as any course of dealing and usage of trade, shall be construed whenever reasonable as consistent with each other, but when such construction is unreasonable, express terms shall control course of performance and course of performance shall control both course of dealing and usage of trade (section 28:1-205).

(3) Subject to the provisions of the next section on modification and waiver, such course of performance shall be relevant to show a waiver or modification of any term inconsistent with such course of performance.

(Dec. 30, 1963, 77 Stat. 644, Pub. L. 88-243, § 1.)

HISTORICAL AND STATUTORY NOTES

UNIFORM COMMERCIAL CODE COMMENT

Prior Uniform Statutory Provision

No such general provision but concept of this section recognized by terms such as "course of dealing", "the circumstances of the case," "the conduct of the parties," etc., in Uniform Sales Act.

Purposes

1. The parties themselves know best what they have meant by their words of agreement and their action under that agreement is the best indication of what that meaning was. This section thus rounds out the set of factors which determines the meaning of the "agreement" and therefore also of the "unless otherwise agreed" qualification to various provisions of this Article.

2. Under this section a course of performance is always relevant to determine the meaning of the agreement. Express mention of course of performance elsewhere in this Article carries no contrary implication when there is a failure to refer to it in other sections.

3. Where it is difficult to determine whether a particular act merely sheds light on the meaning of the agreement or represents a waiver of a term of the agreement, the preference is in favor of "waiver" whenever such construction, plus the application of the provisions on the reinstatement of rights waived (see Section 2-209), is needed to preserve the flexible character of commercial contracts and to prevent surprise or other hardship.

4. A single occasion of conduct does not fall within the language of this section but other sections such as the ones on silence after acceptance and failure to specify particular defects can affect the parties' rights on a single occasion (see Sections 2-605 and 2-607).
