1. (1) An agreement for sale which is otherwise sufficiently definite (subsection (3) of Section 12A-2-204) to be a contract is not made invalid by the fact that it leaves particulars of performance to be specified by one of the parties. Any such specification must be made in good faith and within limits set by commercial reasonableness.

2. (2) Unless otherwise agreed specifications relating to assortment of the

   goods are at the buyer's option and except as otherwise provided in subsections (1) (c) and (3) of Section 12A- 2-319 specifications or arrangements relating to shipment are at the seller's option.

3. (3) Where such specification would materially affect the other

   1. (a) is excused for any resulting delay in his own performance; and

   2. (b) may also either proceed to perform in any reasonable manner or after the time for a material part of his own performance treat the failure to specify or to cooperate as a breach by failure to deliver or accept the goods.

      Oklahoma Code Comment

      Prior Common Law: Under the common law decisions, most courts refused to uphold contracts in which either

      party was given an uncontrolled option to specify particulars of performance, or in which the parties "agree to agree." The agreement was held unenforceable either because of uncertainty or want of mutuality. Thus, an agreement of the seller to sell "either my Ford or my Chevrolet, as I may specify," was unenforceable. However, options given as to mode of delivery were generally enforceable, and, of course, if no time was stated for delivery, the courts inferred "reasonable time."

      The purpose of this act is to render enforceable contracts leaving some details to the option of either

      party.

      There are several restrictions:

      First, the parties must intend to enter into contractual relations. This is provided for in the words "An

      agreement for sale which is otherwise sufficiently definite to be a contract . . ."

      Second, the

      party having the option must act in commercial good faith.

      The Commercial Code gives priority of option, not on the mechanical "first in time" basis as many of the previous judicial decisions did, but upon a commercial basis. Thus, options relating to assortment of

      goods are at the buyer's option, and arrangements as to shipment to the sellers. This, of course, is sensible.
