Section 9--326. Priority of Security Interests Created by New Debtor.

(a) Subordination of security interest created by new debtor. Subject
to subsection (b), a security interest that is created by a new debtor
in collateral in which the new debtor has or acquires rights and is
perfected solely by a filed financing statement that would be
ineffective to perfect the security interest but for the application of
Section 9--316(i)(1) or 9--508 is subordinate to a security interest in
the same collateral which is perfected other than by such a filed
financing statement.

(b) Priority under other provisions; multiple original debtors. The
other provisions of this part determine the priority among conflicting
security interests in the same collateral perfected by filed financing
statements described in subsection (a). However, if the security
agreements to which a new debtor became bound as debtor were not entered
into by the same original debtor, the conflicting security interests
rank according to priority in time of the new debtor's having become
bound.
