8. 4. The application of either the rule of subsection (3) Section 9-407 [Maine cite section 9-1407] or the rule of subsection (4) (3) to the grant by the lessor of a security interest in the lessor's right to future payment under the lease contract may produce the same result. Both subsections provisions generally protect security transfers by the lessor in particular because the creation by the lessor of a security interest or the enforcement of that interest generally will not prejudice the lessee's rights if it does not result in a delegation of the lessor's duties. To the contrary, the receipt of loan proceeds or relief from the enforcement of an antecedent debt normally should enhance the lessor's ability to perform its duties under the lease contract. Nevertheless, there are circumstances where relief might be justified. For example, if ownership of the goods is transferred pursuant to enforcement of a security interest to a party whose ownership would prevent the lessee from continuing to possess the goods, relief might be warranted. See 49 U.S.C. § 1401(a) and (b) which places limitations on the operation of aircraft in the United States based on the citizenship or corporate qualification of the registrant.

9. 5. Relief on the ground of material prejudice when the lease agreement does not prohibit the transfer or make it an event of default should be afforded only in extreme circumstances, considering the fact that the party asserting material prejudice did not insist upon a provision in the lease agreement that would protect against such a transfer.
