Okla. Stat. tit. 12A, § 2-311
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.
