Section 9--110. Security Interests Arising Under Article 2 or 2-A.
    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.
