D) CHANGE OF CONTROL SITUATIONS. In the event of a Change of Control of Company at any time after the date hereof, Employee may voluntarily terminate employment with Company up until twelve (12) months after the Change of Control for "Good Reason" and, subject to Section 7(f), (y) be entitled to receive in a lump sum (i) any compensation due but not yet paid through the date of termination and (ii) in lieu of any further salary payments from the date of termination to the end of the then existing term, an amount equal to the Termination Compensation times 2.99, and (z) shall continue to participate in the same group employee benefit plans or programs for which officers of the Company generally are eligible, or comparable plans or coverage, for a period of two years following termination of employment by the Employee, on the same terms as were in effect either (A) at the date of such termination, or (B) if such plans and programs in effect prior to the Change of Control of Company are, considered together as a whole, materially more generous to the offices of Company, then at the date of Change of Control. Any equity based incentive compensation (including but not limited to stock options, SARs, etc.) shall fully vest and be immediately exercisable in full upon a Change in Control, not withstanding any provision in any applicable plan. The Company shall pay any such benefits to the same extent as they were so paid prior to the termination or the Change of Control of Company. "Good Reason" shall mean the occurrence of any of the following events without the Employee's express written consent: 18 (i) The assignment to the Employee of duties inconsistent with the position and status of the Employee with the Company immediately prior to the Change of Control; (ii) A reduction by the Company in the Employee's pay grade or base salary as then in effect, or the exclusion of Employee from participation in the Company's benefit plans in which he previously participated as in effect at the date hereof or as the same may be increased from time-to-time during the Term, or Company's failure to increase (within twelve (12) months of the Employee's last increase in base salary) the Employee's base salary in an amount which at least equals, on a percentage basis, the average percentage increase in base salary for all executives entitled to participate in Company's executive incentive plans for which the Employee was eligible in the preceding 12 months; or (iii) An involuntary relocation of the Employee more than fifty (50) miles from the location where the Employee worked immediately prior to the Change in Control or the breach by the Company of any material provision of this Agreement; or (iv) Any purported termination of the employment of Employee by Company which is not effected in accordance with this Agreement. A "Change of Control" shall be deemed to have occurred if (i) any person or group of persons (as defined in Section 13(d) and 14(d) of the Securities Exchange Act of 1934) together with its affiliates, excluding employee benefit plans of Company, becomes, directly or indirectly, the "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of securities of Company representing 20% or more of the combined voting power of Company's then outstanding securities; or (ii) during the then existing term of the Agreement, as a result of a proxy contest, merger, consolidation or sale of assets, or as a result of any combination for the foregoing individuals who at the beginning of any year period during such term constitute the Company's Board of Directors, plus new directors whose election by Company's shareholders is approved by a vote of at least two thirds of the outstanding voting shares of the Company, cease for any reason during such year period to constitute at least two thirds of the members of such Board of Directors; or (iii) the shareholders of the Company approve a merger or consolidation of the Company with any other corporation or entity which regardless of which entity is the survivor, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or being converted into voting securities of the surviving entity) at least 60% of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; or (iv) the shareholders of the Company approve a plan of complete liquidation or winding-up of the Company or an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets; or (v) any event which the Company's Board of Directors determines should constitute a Change of Control. E) EMPLOYEE'S RIGHT TO PAYMENTS. In receiving any payments pursuant to this Section 7, Employee shall not be obligated to seek other employment or take 19 any other action by way of mitigation of the amounts payable to the Employee hereunder, and such amounts shall not be reduced or terminated whether or not the Employee obtains other employment. F) REDUCTION IN AGREEMENT PAYMENTS. Notwithstanding anything in this Agreement to the contrary, if any of the payments provided for under this Agreement (the "Agreement Payments"), together with any other payments that the Employee has the right to receive (such other payments together with the Agreement Payments are referred to as the "Total Payments"), would constitute a "parachute payment" as defined in Section 280G(b)(2) of the Internal Revenue code of 1986, as amended (the "Code") (a "Parachute Payment"), the Agreement Payments shall be reduced by the smallest amount necessary so that no portion of such Total Payments would be Parachute Payments. In the event the Company shall make an Agreement Payment to the Employee that would constitute a Parachute Payment, the Employee shall return such payment to the Company (together with interest at the rate set forth in Section 1274(b)(2)(B) of the Code). For purposes of determining whether and the extent to which the Total Payments constitute the Parachute Payments, no portion of the Total Payments the receipt of which Employee has effectively waived in writing shall be taken into account. 8. Covenant Not to Compete. Employee agrees that during his employment with the Company and for a period of one (1) year following the termination of his employment with the Company, for whatever reason: a) Employee shall not, directly or indirectly, own any interest in, manage, operate, control, be employed by , render advisory services to, or participate in the management or control of any business that operates in the same business as the Company, which Employee and the Company specifically agree as the business of fabricating (wafering, preforming, and faceting), marketing and distributing moissanite gemstones or other diamond simulants to the gem and jewelry industry (the "Business"), unless Employee's duties, responsibilities and activities for and on behalf of such other business are not related in any way to such other business's products which are in competition with the Company's products at the time of termination. For purposes of this Section, "competition with the Company" shall mean competition for customers in the United States and in any country in which the Company is selling the Company's products at the time of termination. Employee's ownership of less than one percent of the issued and outstanding stock of a corporation engaged in the Business shall not by itself be deemed to be a violation of this Agreement. Employee recognizes that possible restriction on his activities which may occur as a result of his performance of his obligations under Paragraph 8(a) are substantial, but that such restriction is required for the reasonable protection of the Company. b) Employee shall not, directly or indirectly, influence or attempt to influence any customer of the Company to discontinue its purchase of any product of the Company which is manufactured or sold by the Company at the time of termination of Employee's employment or to divert such purchases to any other person, firm or employer. 20 c) Employee shall not, directly or indirectly, interfere with, disrupt or attempt to disrupt the relationship, contractual or otherwise between the Company and any of its suppliers. d) Employee shall not, directly or indirectly, solicit any employee of the Company to work for any other person, firm or employer. 9.

During and after his employment by the Company, Employee shall not, directly or indirectly, disclose the Confidential Information, except as is required in the course of his Employment under this Agreement. All confidential Information as well as records, files, memoranda, reports, plans, drawings, documents, models, equipment and the like, including copies thereof, relating to the Company's business, which Employee shall prepare or use or come into contact with during the course of his employment, shall be and remain the Company's sole property, and upon termination of Employee's employment with the Company, Employee shall return all such materials to the Company. 10. Proprietary Information. Employee shall assign to Company, its successors or assigns all of the Employee's rights to copyrightable works and inventions which, during the period of Employee's employment by the Company or its successors in business, Employee makes or conceives, either solely or jointly with others, relating to any subject matter with which Employee's work for the Company is or may be concerned ("Proprietary Information"). Employee shall promptly disclose in writing to the Company such copyrightable works and inventions and, without charge to the Company, to execute, acknowledge and deliver all such further papers, including applications for copyrights and patents for such copyrightable works and inventions, if any, in all countries and to vest title thereto in the Company, it's successors, assigns, or nominees. Upon termination of Employee's employment hereunder, Employee shall return to the Company or its successors or assigns, as the case may be, any Proprietary Information. The obligation of Employee to assign the rights to such copyrightable works and inventions shall survive the discontinuance or termination of this Agreement for any reason. 11. Severability. In the event that any provision of any paragraph of this Agreement shall be deemed to be invalid or unenforceable for any reason whatsoever, it is agreed such invalidity or unenforceability shall not affect any other provision of such paragraph of this Agreement, and the remaining terms, covenants, restrictions, or provisions in such paragraph and in the Agreement shall remain in full force and effect and any court of competent jurisdiction may so modify the objectionable provision to make it valid, reasonable and enforceable. 12.
