Okla. Stat. tit. 14A, § 14A-3-208: Advances to perform covenants of debtor

(1) If the agreement with respect to a consumer loan,

refinancing, or consolidation contains covenants by the debtor to

perform certain duties pertaining to insuring or preserving

collateral and if the lender pursuant to the agreement pays for

performance of the duties on behalf of the debtor the lender may add

the amounts paid to the debt. In the case of covenants as to duties

other than the payment of taxes and insuring the collateral, the

lender shall give written notice to the debtor setting forth the

duties to be performed and a statement of the amount to be charged

for the performance of said duties. Said written notice shall be by

certified mail to the last-known address of the debtor, at least

thirty (30) days prior to the commencement of the performance of the

specified duties, unless otherwise agreed in writing by the lender

and debtor. The debtor, prior to commencement of performance, shall

have the option to make alternative arrangements for compliance with

the covenants. Within a reasonable time after advancing any sums,

he shall state to the debtor in writing the amount of the sums

advanced, any charges with respect to this amount, and any revised

payment schedule, and, if the duties of the debtor performed by the

lender pertain to insurance, a brief description of the insurance

paid for by the lender including the type and amount of coverages.

No further information need be given.

(2) A loan finance charge may be made for sums advanced

pursuant to subsection (1) at a rate not exceeding the rate stated

to the debtor pursuant to the provisions on disclosure (Part 3) with

respect to the loan, refinancing, or consolidation, except that with

respect to a revolving loan account the amount of the advance may be

added to the unpaid balance of the debt and the lender may make a

loan finance charge not exceeding that permitted by the provisions

on loan finance charge for consumer loans (Section 3-201) or for

supervised loans (Section 3-508A), whichever is appropriate.
