Ohio Rev. Code § 1301.310: Subordinated obligations - UCC 1-310.

Subordinated obligations [UCC 1-310]

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. Subordination does not create a security interest as against either the common debtor or a subordinated creditor.
