(a) Conflicting perfected security interests and agricultural liens rank according to priority in time of filing or perfection. Priority dates from the earlier of the time a filing covering the collateral is first made or the security interest or agricultural lien is first perfected, if there is no period thereafter when there is neither filing nor perfection.

(b) A perfected security interest or agricultural lien has priority over a conflicting unperfected security interest or agricultural lien.

(c) The first security interest or agricultural lien to attach or become effective has priority if conflicting security interests and agricultural liens are unperfected.

(2) For the purposes of subsection (1)(a) of this section:

(a) The time of filing or perfection as to a security interest in collateral is also the time of filing or perfection as to a security interest in proceeds; and

(b) The time of filing or perfection as to a security interest in collateral supported by a supporting obligation is also the time of filing or perfection as to a security interest in the supporting obligation.

(3) Except as otherwise provided in subsection (6) of this section, a security interest in collateral which qualifies for priority over a conflicting security interest under ORS 79.0327, 79.0328, 79.0329, 79.0330 or 79.0331 also has priority over a conflicting security interest in:

(a) Any supporting obligation for the collateral; and

(b) Proceeds of the collateral if:

(A) The security interest in proceeds is perfected;

(B) The proceeds are cash proceeds or of the same type as the collateral; and

(C) In the case of proceeds that are proceeds of proceeds, all intervening proceeds are cash proceeds, proceeds of the same type as the collateral or an account relating to the collateral.

(4) Subject to subsection (5) of this section and except as otherwise provided in subsection (6) of this section, if a security interest in chattel paper, deposit accounts, negotiable documents, instruments, investment property or letter-of-credit rights is perfected by a method other than filing, conflicting perfected security interests in proceeds of the collateral rank according to priority in time of filing.

(5) Subsection (4) of this section applies only if the proceeds of the collateral are not cash proceeds, chattel paper, negotiable documents, instruments, investment property or letter-of-credit rights.

(6) Subsections (1) to (5) of this section are subject to:

(a) Subsection (7) of this section and the other provisions of ORS 79.0301 to 79.0342;

(b) ORS 74.2100 with respect to a security interest of a collecting bank;

(c) ORS 75.1180 with respect to a security interest of an issuer or nominated person; and

(d) ORS 79.0110 with respect to a security interest arising under ORS chapter 72 or 72A.

(7) A perfected agricultural lien on collateral has priority over a conflicting security interest in or agricultural lien on the same collateral if the statute creating the agricultural lien so provides. [2001 c.445 §42]
