Okla. Stat. tit. 12A, § 12A-2-610: Anticipatory Repudiation

When either party repudiates the contract with respect to a

performance not yet due the loss of which will substantially impair

the value of the contract to the other, the aggrieved party may

(a) for a commercially reasonable time await performance

by the repudiating party; or

(b) resort to any remedy for breach (Section 2-703 or

Section 2-711), even though he has notified the repudiating party

that he would await the latter's performance and has urged

retraction; and

(c) in either case suspend his own performance or proceed

in accordance with the provisions of this article on the seller's

right to identify goods to the contract notwithstanding breach or to

salvage unfinished goods (Section 2-704).
