4-1-303.    Course of performance -- Course of dealing -- Usage of trade.
    (a)  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)  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)  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  facts. 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)  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)  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)  Subject  to    4-2-209, a course of performance is relevant to show a waiver or  modification of any term inconsistent with the course of performance.
(g)  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.
