Okla. Stat. tit. 12A, § 12A-1-310: Subordination of obligations

Subordination of obligations.

An obligation may be issued as subordinated to performance of

another obligation of the person obligated, or a creditor may

subordinate its right to performance of an obligation by agreement

with either the person obligated or another creditor of the person

obligated. Such a subordination does not create a security interest

as against either the common debtor or a subordinated creditor.
