perfection or nonperfection, and the priority of a security interest

in the certificated security represented thereby.

(2) The local law of the issuer's jurisdiction as specified in

subsection (d) of Section 8-110 of this title governs perfection,

the effect of perfection or nonperfection, and the priority of a

security interest in an uncertificated security.

(3) The local law of the securities intermediary's jurisdiction

as specified in subsection (e) of Section 8-110 of this title

governs perfection, the effect of perfection or nonperfection, and

the priority of a security interest in a security entitlement or

governs perfection, the effect of perfection or nonperfection, and

(5) Paragraphs (2), (3), and (4) of this subsection apply even

if the transaction does not bear any relation to the jurisdiction.

(b) The following rules determine a commodity intermediary's

jurisdiction for purposes of this part:

agreement is governed by the law of a particular jurisdiction, that

jurisdiction is the commodity intermediary's jurisdiction.

(3) If neither paragraph (1) nor paragraph (2) of this

subsection applies and an agreement between the commodity

intermediary and commodity customer governing the commodity account

office in a particular jurisdiction, that jurisdiction is the
