§ 9-209. DUTIES OF SECURED PARTY IF ACCOUNT DEBTOR HAS BEEN NOTIFIED OF ASSIGNMENT.
Except as otherwise provided in subsection (c), this section applies if:
(1) there is no outstanding secured obligation; and
(2) the secured party is not committed to make advances, incur obligations, or otherwise give value.
