Okla. Stat. tit. 12A, § 12A-2A-401: Insecurity; adequate assurance of performance

INSECURITY; ADEQUATE ASSURANCE OF PERFORMANCE

(1) A lease contract imposes an obligation on each party that

the other's expectation of receiving due performance will not be

impaired.

(2) If reasonable grounds for insecurity arise with respect to

the performance of either party, the insecure party may demand in

writing adequate assurance of due performance. Until the insecure

party receives that assurance, if commercially reasonable the

insecure party may suspend any performance for which he has not

already received the agreed return.

(3) A repudiation of the lease contract occurs if assurance of

due performance adequate under the circumstances of the particular

case is not provided to the insecure party within a reasonable time,

not to exceed thirty (30) days after receipt of a demand by the

other party.

(4) Between merchants, the reasonableness of grounds for

insecurity and the adequacy of any assurance offered must be

determined according to commercial standards.

(5) Acceptance of any nonconforming delivery or payment does

not prejudice the aggrieved party's right to demand adequate

assurance of future performance.
