                   automatically terminate on the date of death, which shall be
                   the last day of the Term.

              B)   TERMINATION FOR JUST CAUSE. The Company shall have the right
                   to terminate the Employee's employment under this Agreement
                   at any time for Just Cause, which termination shall be
                   effective immediately. Termination for "Just Cause" shall
                   include termination for the Employee's personal dishonesty,
                   gross incompetence, willful misconduct, breach of fiduciary
                   duty involving personal profit, intentional failure to
                   perform stated duties, willful violation of any law, rule,
                   regulation (other than traffic violations or similar
                   offenses), written Company policy or final cease-and-desist
                   order, conviction of a felony or of a misdemeanor involving
                   moral turpitude, unethical business practices, in connection
                   with the Company's business, misappropriation of the
                   Company's assets (determined on a reasonable basis),
                   disability or material breach of any other provision of this
                   Agreement, provided that the Employee has received written
                   notice from the Company of such material breach and such
                   breach remains uncured thirty days after the delivery of such
                   notice. For purposes of this subsection, the term
                   "disability" means the inability of Employee, due to the
                   condition of his physical, mental, or emotional health, to
                   satisfactorily perform the duties of his employment hereunder
                   for a continuous three month period; provided further that if
                   the Company furnishes long term disability insurance for the
                   Employee, the term "disability" shall mean that continuous
                   period sufficient to allow for the long term disability
                   payments to commence pursuant to the Company's long term
                   disability insurance policy. In the event the Employee's
                   employment under this Agreement is terminated for Just Cause,
                   the Employee shall have no


                                       17


                   right to receive compensation or other benefits under this
                   Agreement for any period after such termination.

              C)   TERMINATION WITHOUT CAUSE. The Company may terminate the
                   Employee's employment other than for "Just Cause," as
                   described in Subsection (b) above, at any time upon written
                   notice to the Employee, which termination shall be effective
                   immediately. In the event the Company terminates Employee
                   pursuant to this Subsection (c), (i) the Employee will
                   receive the Base Salary for the remainder of the then
                   existing term, or for a period of seven calendar months,
                   whichever is greater, regardless of the contract term
                   ("Termination Compensation"), so long as the Employee
                   complies with Sections 8, 9 and 10 of the Agreement and (ii)
                   the Company shall take such action as may be required to vest
                   any unvested benefits of the Employee under any employee
                   stock-based or other benefit plan or arrangement, not
                   withstanding any provision in any applicable plan. Such
                   amounts shall be payable at the times such amounts would have
                   been paid in accordance with Section 4 In addition, Employee
                   shall continue to participate in the same group
                   hospitalization plan, health care plan, dental care plan,
                   life or other insurance or death benefit plan, and any other
                   present or future similar group employee benefit plan or
                   program for which officers of the Company generally are
                   eligible, on the same terms as were in effect prior to the
                   Employee's termination, either under the Company's plans or
                   comparable coverage, for all periods Employee receives
                   Termination Compensation. Notwithstanding anything in this
                   Agreement to the contrary, if Employee breaches Sections 8, 9
                   or 10 of this Agreement, the Employee will not be entitled to
                   receive any further compensation or benefits pursuant to this
                   Section 7(c).

              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.   Confidentiality. In the course of his employment with the Company,
              Employee will have access to confidential information, records,
              data, customer lists, lists of product sources, specifications,
              trade secrets and other information which is not generally
              available to the public and which the Company and Employee hereby
              agree is proprietary information of the Company ("Confidential
              Information"). 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.  Governing Law. This Agreement shall be governed and construed in
              accordance with the laws of the State of North Carolina. Each of
              the parties hereto irrevocably submits to the exclusive

              purposes of any suit, action or other proceeding contemplated
              hereby or any transaction contemplated hereby.

         16.  Waiver. The failure of either party to insist in any one or more
              instance, upon performance of the terms and conditions of this
              Agreement, shall not be construed as a waiver or a relinquishment
              of any right granted hereunder or of the future performance of any
              such term or condition.

         17.  Arbitration. Any controversy or claim arising out of or relating
