If any court determines that any of the terms and conditions of Section 7 or this Section 8 are invalid or unenforceable, the remainder of the terms and conditions shall not thereby be affected and shall be given full effect, without regard to the invalid portions. If any court determines that any of the terms and conditions are unenforceable because of the duration of such terms and conditions or the area covered thereby, such court shall have the power to reduce the duration or area of such terms and conditions and, in their reduced form, the terms and conditions shall then be enforceable and shall be enforced.
