(b) The satisfaction of obligations secured by the security interest or agricultural lien under which the disposition is made;
(c) The satisfaction of obligations secured by any subordinate security interest in or other subordinate lien on the collateral if:1. The secured party receives from the holder of the subordinate security interest or other lien an authenticated demand for proceeds before distribution of the proceeds is completed; and
2. In a case in which a consignor has an interest in the collateral, the subordinate security interest or other lien is senior to the interest of the consignor; and

(2) If requested by a secured party, a holder of a subordinate security interest or other lien shall furnish reasonable proof of the interest or lien within a reasonable time after receipt of the request and agree to indemnify the secured party on reasonable terms acceptable to the secured party for damages, including reasonable attorney’s fees and costs, incurred or suffered by the secured party if the subordinate holder did not have the right to receive the amounts to be paid to it. Unless the holder complies, the secured party need not comply with the holder’s demand under paragraph (1)(c).
(3) A secured party need not apply or pay over for application noncash proceeds of disposition under s. 679.610 unless the failure to do so would be commercially unreasonable.

(4) If the security interest under which a disposition is made secures payment or performance of an obligation, after making the payments and applications required by subsection (1) and permitted by subsection (3):(a) Unless paragraph (1)(d) requires the secured party to apply or pay over cash proceeds to a consignor, the secured party shall account to and pay a debtor for any surplus; and

(6) The surplus or deficiency following a disposition is calculated based on the amount of proceeds that would have been realized in a disposition complying with this part to a transferee other than the secured party, a person related to the secured party, or a secondary obligor if:(a) The transferee in the disposition is the secured party, a person related to the secured party, or a secondary obligor; and
(b) The amount of proceeds of the disposition is significantly below the range of proceeds that a complying disposition to a person other than the secured party, a person related to the secured party, or a secondary obligor would have brought.
(7) A secured party that receives cash proceeds of a disposition in good faith and without knowledge that the receipt violates the rights of the holder of a security interest or other lien that is not subordinate to the security interest or agricultural lien under which the disposition is made:(a) Takes the cash proceeds free of the security interest or other lien;
(b) Is not obligated to apply the proceeds of the disposition to the satisfaction of obligations secured by the security interest or other lien; and
(c) Is not obligated to account to or pay the holder of the security interest or other lien for any surplus.
(8) If the secured party in good faith cannot determine the validity, extent, or priority of a subordinate security interest or other lien or there are conflicting claims of subordinate interests or liens, the secured party may commence an interpleader action with respect to remaining proceeds in excess of $2,500 in the circuit or county court, as applicable based upon the amount to be deposited, where the collateral was located or collected or in the county where the debtor’s chief executive office or principal residence is located in this state, as applicable. The interpleading secured party and any other parties in the interpleader action shall only be entitled to recover attorney’s fees and costs as permitted in s. 679.608(3).
