If any provision of this chapter is held by any court or by any federal or state agency of competent jurisdiction, to be invalid as conflicting with any federal or state law, rule or regulation now or hereafter in effect, or is held by such court or agency to be modified in any way in order to conform to the requirements of any such law, rule or regulation, such provision shall be considered a separate, distinct and independent part of this chapter, and such holding shall not affect the validity and enforceability of all other provisions hereof. In the event that such law, rule or regulation is subsequently repealed, rescinded, amended or otherwise changed, so that the provision thereof which had previously been held invalid or modified is no longer in conflict with such law, rule or regulation, such provision shall thereupon return to full force and effect and shall thereafter be binding on grantor and grantee, provided that grantor shall give grantee thirty days written notice of such change before requiring compliance with such provision or such longer period of time as may be reasonably required for grantee to comply with such provision.
