This Agreement shall inure to the benefit of and be binding upon the Company and the Executive, and their respective successors, executors, administrators, representatives, heirs and permitted assigns.

If any portion or provision of this Agreement shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the application of such provision in such circumstances shall be deemed modified to permit its enforcement to the maximum extent permitted by law, and both the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable and the remainder of this Agreement shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.
