(a) After default, a secured party has the rights provided in

this part and, except as otherwise provided in Section 1-9-602 of

this title, those provided by agreement of the parties. A secured

party:

(1) may reduce a claim to judgment, foreclose, or otherwise

enforce the claim, security interest, or agricultural lien by any

available judicial procedure, but Section 686 of Title 12 of the

Oklahoma Statutes, shall not apply to the enforcement of a claim,

security interest, or agricultural lien under this article except as

provided in Section 1-9-604 of this title where the procedure is in

accordance with the rights of the parties with respect to real

property; and

(2) if the collateral is documents, may proceed either as to

the documents or as to the goods they cover.

(b) A secured party in possession of collateral or control of

collateral under Section 7-106, 1-9-104, 1-9-105, 1-9-106, 1-9-107,

or 1-9-107A of this title has the rights and duties provided in

Section 1-9-207 of this title.

(c) The rights under subsections (a) and (b) of this section

are cumulative and may be exercised simultaneously.

(d) Except as otherwise provided in subsection (g) of this

section and Section 1-9-605 of this title, after default, a debtor

and an obligor have the rights provided in this part and by

agreement of the parties.

(e) If a secured party has reduced its claim to judgment, the

lien of any levy that may be made upon the collateral by virtue of

an execution based upon the judgment relates back to the earliest

of:

(1) the date of perfection of the security interest or

agricultural lien in the collateral;

(2) the date of filing a financing statement covering the

collateral; or

(3) any date specified in a statute under which the

agricultural lien was created.

(f) A sale pursuant to an execution is a foreclosure of the

security interest or agricultural lien by judicial procedure within

the meaning of this section. A secured party may purchase at the

sale and thereafter hold the collateral free of any other

requirements of this article.

(g) Except as otherwise provided in subsection (c) of Section

1-9-607 of this title, this part imposes no duties upon a secured

party that is a consignor or is a buyer of accounts, chattel paper,

payment intangibles, or promissory notes.
