party to enforce the same. Waiver by any party hereto of any breach or default by another party of any term or provision of this Agreement shall not operate as a waiver of any other breach or default. In the event that any one or more of the
provisions of this Agreement is held to be invalid, illegal or unenforceable, the validity, legality and enforceability of the remainder of the Agreement shall not in any way be affected or impaired thereby, or, if any of the provisions contained in
this Agreement are held to be excessively broad as to duration, activity or subject, such provisions shall be construed by limiting and reducing them so as to be enforceable to the maximum extent allowed by applicable law. In addition, upon a
finding by a court (or other tribunal) that the Release in Section 11 above is unenforceable, you agree, upon the request of the Company, promptly to execute a new release as close in scope as possible to the one in Section 11 that is
enforceable.
