a. Continuing priority over lien creditor; perfection requirements satisfied. A security interest that is enforceable immediately before this title takes effect and would have priority over the rights of a person that becomes a lien creditor at that time is a perfected security interest under this title if, when this takes effect, the applicable requirements for enforceability and perfection under this title are satisfied without further action.
b. Continuing priority over lien creditor; perfection requirements not satisfied. Except as otherwise provided in § 8.9A-705, if, immediately before this title takes effect, a security interest is enforceable and would have priority over the rights of a person that becomes a lien creditor at that time, but the applicable requirements for enforceability or perfection under this title are not satisfied when this takes effect, the security interest:
1. is a perfected security interest for one year after this takes effect;
2. remains enforceable thereafter only if the security interest becomes enforceable under § 8.9A-203 before the year expires; and
3. remains perfected thereafter only if the applicable requirements for perfection under this title are satisfied before the year expires.
c. Notwithstanding subsections (a) and (b) of this section, a lien, pledge or security interest granted by the Commonwealth or a governmental unit of the Commonwealth prior to July 1, 2001, which is enforceable immediately before July 1, 2001, and would have priority over the rights of a person that becomes a lien creditor at that time, shall remain enforceable and continue to have such priority on or after July 1, 2001.
