Maryland Commercial Law Section 9-326

      (a)      Subject to subsection (b), a security interest created by a new debtor which is perfected by a filed financing statement that is effective solely under § 9-508 in collateral in which a new debtor has or acquires rights is subordinate to a security interest in the same collateral which is perfected other than by a filed financing statement that is effective solely under § 9-508 of this title.

      (b)      The other provisions of this subtitle determine the priority among conflicting security interests in the same collateral perfected by filed financing statements that are effective solely under § 9-508 of this title. 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.
