(a) Individuals, partnerships, banks, corporations, and other legal entities may, on any loans or extensions of credit made by them, charge or impose the same rate of interest or finance charge to the same extent and under the same circumstances and conditions as any federal or state chartered or licensed lending institution having its principal place of business in Alabama;  provided, however, that any individual or partnership charging or imposing interest or finance charges in excess of that permitted such lending institutions under other applicable law shall be subject to the same penalties prescribed in such other applicable law or laws for such excessive interest or finance charges.

(b) The provisions of this section are cumulative and nothing herein contained shall diminish rights or powers otherwise existing. The provisions of this section, as amended, shall have retroactive effect to May 14, 1979, when it became law;  provided, however, that there shall be no change of interest rates on secured loans in existence as of April 25, 1980. Any actions taken or contracts made in accordance with the provisions of this section since May 14, 1979 are hereby ratified, validated, and confirmed.
