Okla. Stat. tit. 14A, § 14A-3-206

(1) If a debtor owes an unpaid balance to a lender with respect

to a consumer loan, refinancing, or consolidation, other than one

made under Section 3-508B of this title, and becomes obligated on

another consumer loan, refinancing, or consolidation with the same

lender, the parties may agree to a consolidation resulting in a

single schedule of payments. If the previous consumer loan,

refinancing, or consolidation was not precomputed, the parties may

agree to add the unpaid amount of principal and accrued charges on

the date of consolidation to the principal with respect to the

subsequent loan. If the previous consumer loan, refinancing, or

consolidation was precomputed, the parties may agree to refinance

the unpaid balance pursuant to the provisions on refinancing

(Section 3-205) and to consolidate the principal resulting from the

refinancing by adding it to the principal with respect to the

subsequent loan. In either case the lender may contract for and

receive a loan finance charge based on the aggregate principal

resulting from the consolidation at a rate not in excess of that

permitted by the provisions on loan finance charge for consumer

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

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

(2) The parties may agree to consolidate the unpaid balance of

a consumer loan, other than one made under Section 3-508B of this

title, with the unpaid balance of a consumer credit sale. The

parties may agree to refinance the previous unpaid balance pursuant

to the provisions on refinancing sales (Section 2-205) or the

provisions on refinancing loans (Section 3-205), whichever is

appropriate, and to consolidate the amount financed resulting from

the refinancing or the principal resulting from the refinancing by

adding it to the amount financed or principal with respect to the

subsequent sale or loan. The aggregate amount resulting from the

consolidation shall be deemed principal, and the creditor may

contract for and receive a loan finance charge based on the

principal at a rate not in excess of that permitted by the

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

or the provisions on loan finance charge for supervised loans

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