“(m) any lien in relation to the refinancing of any liability or obligation which is the subject of a lien permitted in clauses (a), (c), (d), (e), (f), (g), (h) or (i) above; provided that any such lien is limited to all or part of the same property or assets that secured the liability or obligation being refinanced; and”.
