(A) Except as otherwise provided in this section, priority between conflicting security interests and agricultural liens in the same collateral shall be determined according to the following rules:

1. (1) 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.
2. (2) A perfected security interest or agricultural lien has priority over a conflicting unperfected security interest or agricultural lien.
3. (3) The first security interest or agricultural lien to attach or become effective has priority if conflicting security interests and agricultural liens are unperfected.

(B) For the purpose of division (A)(1) of this section:

1. (1) 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
2. (2) 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.

(C) Except as otherwise provided in division (F) of this section, a security interest in collateral which qualifies for priority over a conflicting security interest under section 1309.327, 1309.328, 1309.329, 1309.330, or 1309.331 of the Revised Code also has priority over a conflicting security interest in:

1. (1) Any supporting obligation for the collateral; and

2. (2) Proceeds of the collateral if:

   1. (a) The security interest in proceeds is perfected.
   2. (b) The proceeds are cash proceeds or of the same type as the collateral; and
   3. (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.

(F) Divisions (A) to (E) of this section are subject to:

1. (1) Division (G) of this section and the other provisions of sections 1309.301 to 1309.342 of the Revised Code;
2. (2) Section 1304.20 of the Revised Code with respect to a security interest of a collecting bank;
3. (3) Section 1305.18 of the Revised Code with respect to a security interest of an issuer or nominated person; and
4. (4) Section 1309.110 of the Revised Code with respect to a security interest arising under Chapter 1302. or 1310. of the Revised Code.
