“C. No amendment to or repeal of this Article VII, or adoption of any provision of these Articles of Incorporation inconsistent with this Article VII, or a change in the law, shall adversely affect any elimination or limitation of liability, or other right or protection, that is based upon this Article VII and

pertains to any act, conduct, omission, or circumstance that occurred or existed before the amendment, repeal, adoption, or change. No change in the law shall reduce or eliminate the rights and protections set forth in this Article VII unless the change in law specifically requires the reduction or elimination.
