Acknowledgment. ADVISOR HAS READ AND UNDERSTANDS SECTION 8, WHICH DISCUSSES ARBITRATION. ADVISOR UNDERSTANDS THAT BY SIGNING THIS AGREEMENT, ADVISOR AGREES TO SUBMIT ANY CLAIMS ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE, BREACH OR TERMINATION THEREOF, TO BINDING ARBITRATION, EXCEPT AS PROVIDED IN SECTION 8(d), AND THAT THIS ARBITRATION CLAUSE CONSTITUTES A WAIVER OF ADVISOR’S RIGHT TO A JURY TRIAL AND RELATES TO THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THE RELATIONSHIP BETWEEN THE PARTIES.

Acknowledgment. Executive hereby acknowledges that the provisions of this Section 4 are reasonable and necessary to protect the legitimate interests of the Company and that any violation of this Section 4 by Executive will cause substantial and irreparable harm to the Company to such an extent that monetary damages alone would be an inadequate remedy therefor. Executive represents and warrants that Executive is not subject to any other agreements prohibiting the performance of Executive’s obligations under this Agreement, including any non-competition agreement.

Acknowledgment. Executive acknowledges that the consideration provided in this Agreement is good and valuable consideration in exchange for the Agreement, and includes payments and benefits to which she is not otherwise entitled.

Acknowledgment. Executive hereby acknowledges that he shall have no rights hereunder unless and until all circumstances constituting a Qualifying Termination shall have occurred.

Acknowledgment. The Employee has carefully read and considered the provisions of Sections 8 and 9 hereof and agrees that the restrictions set forth in such sections are fair and reasonable and are reasonably required for the protection of the interests of the Corporation, its officers, directors, shareholders, and other employees, for the protection of the business of the Corporation, and to ensure that the Employee devotes the Employee’s entire professional time, energy, and skills to the business of the Corporation. The Employee acknowledges that he is qualified to engage in businesses other than that described in Section 9. It is the belief of the parties, therefore, that the best protection that can be given to the Corporation that does not in any way infringe upon the rights of the Employee to engage in any unrelated businesses is to provide for the restrictions described in Section 9. In view of the substantial harm which would result from a breach by the Employee of Sections 8 or 9, the parties agree that the restrictions contained therein shall be enforced to the maximum extent permitted by law as more particularly set forth in Section 10(b) below. In the event that any of said restrictions shall be held unenforceable by any court of competent jurisdiction, the parties hereto agree that it is their desire that such court shall substitute a reasonable judicially enforceable limitation in place of any limitation deemed unenforceable and that as so modified, the covenant shall be as fully enforceable as if it had been set forth herein by the parties.
