A security interest arising under Section 2-401, 2-505, 2-711(3), or 2A-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 2A; and
(4) the security interest has priority over a conflicting security interest created by the debtor.
