(a) Subject to subsections (a1), (c), and (d) of this section, any security instrument that conforms to the requirements of this Article shall, from the time and date of registration thereof, have the same priority to the extent of all future advances and future obligations secured by it, and all interest accruing thereon, as if all the advances had been made, all the obligations incurred, and all the interest accrued at the time the security instrument was registered.

(a1) Subject to subsections (c) and (d) of this section, if at any time the aggregate outstanding principal balance of the obligation or obligations secured by a security instrument that conforms to the requirements of this Article exceeds the maximum principal amount that may be secured by the security instrument at any one time, then, unless the security instrument provides otherwise, the amount in excess and the interest accrued on the amount in excess shall be secured by the security instrument, but (i) the amount in excess and the interest accrued on the amount in excess shall not be afforded the priority provided in subsection (a) of this section and (ii) the priority of the lien of the security instrument with respect to the amount in excess and the interest accrued on the amount in excess shall be determined by other applicable law.
