1303 - Course of performance, course of dealing and usage of trade.

     § 1303.  Course of performance, course of dealing and usage of                trade.        (a)  Course of performance.--A "course of performance" is a     sequence of conduct between the parties to a particular     transaction that exists if:            (1)  the agreement of the parties with respect to the        transaction involves repeated occasions for performance by a        party; and            (2)  the other party, with knowledge of the nature of the        performance and opportunity for objection to it, accepts the        performance or acquiesces in it without objection.        (b)  Course of dealing.--A "course of dealing" is a sequence     of conduct concerning previous transactions between the parties     to a particular transaction that is fairly to be regarded as     establishing a common basis of understanding for interpreting     their expressions and other conduct.        (c)  Usage of trade.--A "usage of trade" is any practice or     method of dealing having such regularity of observance in a     place, vocation or trade as to justify an expectation that it     will be observed with respect to the transaction in question.     The existence and scope of such a usage must be proved as fact.     If it is established that such a usage is embodied in a trade     code or similar record, the interpretation of the record is a     question of law.        (d)  Evidentiary effect.--A course of performance or course     of dealing between the parties or usage of trade in the vocation     or trade in which they are engaged or of which they are or     should be aware is relevant in ascertaining the meaning of the     parties' agreement, may give particular meaning to specific     terms of the agreement and may supplement or qualify the terms     of the agreement. A usage of trade applicable in the place in     which part of the performance under the agreement is to occur     may be so utilized as to that part of the performance.        (e)  Construction in general.--Except as otherwise provided     in subsection (f), the express terms of an agreement and any     applicable course of performance, course of dealing or usage of     trade must be construed whenever reasonable as consistent with     each other. If such a construction is unreasonable:            (1)  express terms prevail over course of performance,        course of dealing and usage of trade;            (2)  course of performance prevails over course of        dealing and usage of trade; and            (3)  course of dealing prevails over usage of trade.        (f)  Waiver or modification.--Subject to section 2209     (relating to modification, rescission and waiver), a course of     performance is relevant to show a waiver or modification of any     term inconsistent with the course of performance.        (g)  Evidence.--Evidence of a relevant usage of trade offered     by one party is not admissible unless that party has given the     other party notice that the court finds sufficient to prevent     unfair surprise to the other party.
