The terms of this Agreement and all of Executive’s rights hereunder shall inure to the benefit of, and be enforceable by, Executive’s personal or legal representatives, executors, administrators, successors, heirs, distributees, devisees and legatees.

4.        Miscellaneous Provisions.

(a)        Waiver. No provision of this Agreement shall be modified, waived or discharged unless the modification, waiver or discharge is agreed to in writing and signed by Executive and by an authorized officer of the Company (other than Executive).

If any term or provision of this Agreement or the application thereof to any circumstance shall, in any jurisdiction and to any extent, be invalid or unenforceable, such term or provision shall be ineffective as to such jurisdiction to the extent of such invalidity or unenforceability without invalidating or rendering unenforceable the remaining terms and provisions of this Agreement or the application of such terms and provisions to circumstances other than those as to which it is held invalid or unenforceable, and a suitable and equitable term or provision shall be substituted therefor to carry out, insofar as may be valid and enforceable, the intent and purpose of the invalid or unenforceable term or provision.

(e)        No Assignment of Benefits. The rights of Executive to payments or benefits under this Agreement shall not be made subject to option or assignment, either by voluntary or involuntary assignment or by operation of law, including (without limitation) bankruptcy, garnishment, attachment or other creditor’s process, and any action in violation of this subsection shall be void, provided the Executive’s estate shall be entitled to receive any benefits that have become payable, but which have not been paid in accordance with Section 1 above.

(f)        Non-solicitation. During the period beginning on the Effective Date and ending one year thereafter, Executive will not, on his own behalf or as a partner, officer, director, employee, agent, or consultant of any other person or entity, directly or indirectly, solicit or induce (or attempt to solicit or induce) any employee of the Company to leave their employment with the Company or to consider employment with any other person or entity.

(g)        Employment Taxes. Any payments made pursuant to this Agreement will be reported on Form W-2 and shall be subject to withholding of applicable income and employment taxes.

(h)        Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original, but all of which together will constitute one and the same instrument.
