A security interest arising under Section 2--401, 2--505, 2--711(3),
or 2-A-508(5) is subject to this article. However, until the debtor
obtains possession of the goods:
(1) the security interest is enforceable, even if Section
9--203(b)(3) has not been satisfied;
(2) filing is not required to perfect the security interest;
(3) the rights of the secured party after default by the debtor
are governed by Article 2 or 2-A; and
(4) the security interest has priority over a conflicting
security interest created by the debtor.
