Okla. Stat. tit. 12A, § 12A-2A-513: Cure by lessor of improper tender or delivery;

replacement.

CURE BY LESSOR OF IMPROPER TENDER

OR DELIVERY; REPLACEMENT

(1) If any tender or delivery by the lessor or the supplier is

rejected because nonconforming and the time for performance has not

yet expired, the lessor or the supplier may seasonably notify the

lessee of the lessor's or the supplier's intention to cure and may

then make a conforming delivery within the time provided in the

lease contract.

(2) If the lessee rejects a nonconforming tender that the

lessor or the supplier had reasonable grounds to believe would be

acceptable with or without money allowance, the lessor or the

supplier may have a further reasonable time to substitute a

conforming tender if he seasonably notifies the lessee.
