Okla. Stat. tit. 52, § 52-549.6: Rights of purchaser

RIGHTS OF PURCHASERS

A purchaser takes free of any oil and gas lien otherwise

applicable to the oil or gas so purchased, and shall be relieved of

any obligations created by subsection A of Section 570.10 of Title

52 of the Oklahoma Statutes, only in the event that either of the

following occur:

1. The purchaser is deemed to be a buyer in the ordinary course

of the first purchaser's business as defined in Article 9; or

2. The purchaser has paid all of the consideration due the

first purchaser, including by exchange of oil or gas, net-out or

set-off, under all applicable enforceable contracts in existence at

the time of the payment.

Notwithstanding the foregoing, the oil and gas lien will

continue uninterrupted in the proceeds paid to or otherwise due the

first purchaser.

Except as specifically set forth in this section, an oil and gas

lien has priority over the rights of any purchaser.
