(a) Subordination of security interest in transferred collateral.  Except as otherwise provided in subsection (b), a security interest created by a debtor is subordinate to a security interest in the same collateral created by another person if:

(1)  The debtor acquired the collateral subject to the security interest created by the other person;

(2)  The security interest created by the other person was perfected when the debtor acquired the collateral; and

(3)  There is no period thereafter when the security interest is unperfected.

(b) Limitation of subsection (a) subordination.  Subsection (a) subordinates a security interest only if the security interest:

(1)  Otherwise would have priority solely under § 6A-9-322(a) or 6A-9-324; or

(2)  Arose solely under § 6A-2-711(3) or 6A-2.1-508(5).
