Okla. Stat. tit. 12A, § 12A-3-603: Tender of Payment

TENDER OF PAYMENT

(a) If tender of payment of an obligation to pay an instrument

is made to a person entitled to enforce the instrument, the effect

of tender is governed by principles of law applicable to tender of

payment under a simple contract.

(b) If tender of payment of an obligation to pay an instrument

is made to a person entitled to enforce the instrument and the

tender is refused, there is discharge, to the extent of the amount

of the tender, of the obligation of an indorser or accommodation

party having a right of recourse with respect to the obligation to

which the tender relates.

(c) If tender of payment of an amount due on an instrument is

made to a person entitled to enforce the instrument, the obligation

of the obligor to pay interest after the due date on the amount

tendered is discharged. If presentment is required with respect to

an instrument and the obligor is able and ready to pay on the due

date at every place of payment stated in the instrument, the obligor

is deemed to have made tender of payment on the due date to the

person entitled to enforce the instrument.
