Okla. Stat. tit. 12A, § 12A-2A-510: Installment lease contracts; rejection and default

INSTALLMENT LEASE CONTRACTS; REJECTION AND

DEFAULT

(1) Under an installment lease contract a lessee may reject any

delivery that is nonconforming if the nonconformity substantially

impairs the value of that delivery and cannot be cured or the

nonconformity is a defect in the required documents; but if the

nonconformity does not fall within subsection (2) of this section

and the lessor or the supplier gives adequate assurance of its cure,

the lessee must accept that delivery.

(2) Whenever nonconformity or default with respect to one or

more deliveries substantially impairs the value of the installment

lease contract as a whole there is a default with respect to the

whole. But, the aggrieved party reinstates the installment lease

contract as a whole if the aggrieved party accepts a nonconforming

delivery without seasonably notifying of cancellation or brings an

action with respect only to past deliveries or demands performance

as to future deliveries.
