Without in any way limiting the generality of the foregoing, the Executive and the Company shall not (and shall cause the officers, directors, employees, shareholders, members, partners, representatives and agents of

-5-

any entity or business directly or indirectly controlled by the Executive and the Company to not) make any disparaging or unfavorable statements to any third party, either orally or in writing, regarding the other party or any present or future subsidiaries, parents or affiliates of the other party or any of their respective principals, officers, directors, shareholders, partners, members, employees, businesses or operations.

13. ENFORCEABILITY OF RESTRICTIVE COVENANTS. The restrictions set forth in this Agreement are considered by the parties hereto to be reasonable for the purposes of protecting the value of the business and goodwill of the Company and the Business. The parties acknowledge that the Company would be irreparably harmed and that monetary damages would not provide an adequate remedy to the Company in the event the covenants contained in this Agreement were not complied with in accordance with their terms. Accordingly, the Executive agrees that any breach or threatened breach by him of any provision of this Agreement shall entitle the Company to seek injunctive and other equitable relief to secure the enforcement of these provisions, in addition to any other remedies which may be available to them, and that they shall be entitled to receive from the Executive reimbursement for all attorneys’ fees and expenses incurred by the Company in enforcing these provisions. In addition to its other rights and remedies, the Company shall have the right to require the Executive, if he breaches any of the covenants contained in this Agreement to account for and pay over to the Company all compensation, profits, money, accruals and other benefits derived or received, directly or indirectly, by such party from the action constituting such breach. If the Executive breaches the restrictive covenants set forth in this Agreement, the running of the time periods described therein shall be tolled for so long as such breach continues. It is the desire and intent of the parties that the provisions of this Agreement be enforced to the fullest extent permissible under the laws and public policies of each jurisdiction in which enforcement is sought. If any provisions of this Agreement relating to the time period, scope of activities or geographic area of restrictions is declared by a court of competent jurisdiction to exceed the maximum permissible time period, such time period, scope of activities and/or geographic area, as the case may be, shall be reduced to the maximum that such court deems enforceable. If any provisions of this Agreement other than those described in the preceding sentence are adjudicated to be invalid or unenforceable, the invalid or unenforceable provisions shall be deemed amended (with respect only to the jurisdiction in which such adjudication is made) in such manner as to render them enforceable and to effectuate as nearly as possible the original intentions and agreement of the parties.

14. OTHER AGREEMENTS. Executive represents that his employment hereunder shall not violate any terms or conditions of the Executive’s employment with any prior employer or any other agreement with the Company.

15. NOTICES. Any notice required or permitted to be given under this Agreement shall be sufficient if in writing and shall be effective when received if sent, postage-prepaid, by certified or registered mail, return receipt requested, or by overnight delivery service against receipt, to the addresses below or to such other address as either party shall designate by written notice to the other:
