5. Multiple Secured Parties. More than one secured party may be entitled to take possession of collateral under this section. Conflicting rights to possession among secured parties are resolved by the priority rules of this Article. Thus, a senior secured party is entitled to possession as against a junior claimant. Non-UCC law governs whether a junior secured party in possession of collateral is liable to the senior in conversion. Normally, a junior who refuses to relinquish possession of collateral upon the demand of a secured party having a superior possessory right to the collateral would be liable in conversion.

6. Secured Party's Right to Disable and Dispose of Equipment on Debtor's Premises. In the case of some collateral, such as heavy equipment, the physical removal from the debtor's plant and the storage of the collateral pending disposition may be impractical or unduly expensive. This section follows former Section 9-503 by providing that, in lieu of removal, the secured party may render equipment unusable or may dispose of collateral on the debtor's premises. Unlike former Section 9-503, however, this section explicitly conditions these rights on the debtor's default. Of course, this section does not validate unreasonable action by a secured party. Under Section 9-610 [Maine cite section 9-1610], all aspects of a disposition must be commercially reasonable.

7. Debtor's Agreement to Assemble Collateral. This section follows former Section 9-503 also by validating a debtor's agreement to assemble collateral and make it available to a secured party at a place that the secured party designates. Similar to the treatment of agreements to permit collection prior to default under Section 9-607 [Maine cite section 9-1607] and former 9-502, however, this section validates these agreements whether or not they are conditioned on the debtor's default. For example, a debtor might agree to make available to a secured party, from time to time, any instruments or negotiable documents that the debtor receives on account of collateral. A court should not infer from this section's validation that a debtor's agreement to assemble and make available collateral would not be enforceable under other applicable law.

8. Agreed Standards. Subject to the limitation imposed by Section 9-603(b) [Maine cite section 9-1603, subsection (2)], this section's provisions concerning agreements to assemble and make available collateral and a secured party's right to disable equipment and dispose of collateral on a debtor's premises are
