Development, all pursuant to the terms and conditions hereinafter set forth; and

          the Employee.

     c)   During the Employment Period, the Employee shall devote his full time
          and best efforts to the business and affairs of the Corporation.
          Notwithstanding the foregoing, the Employee shall be permitted to
          serve on the board of directors of commercial and charitable
          organization and to make investments which are not related to the
          business and affairs of the Corporation for which he may receive
          compensation, so long as such activities or investments do not
          interfere with the performance of the Employee's duties and
          obligations hereunder. Employee and the Board of Directors will
          periodically review such outside commitments to insure that such
          commitments do not interfere with the Employee's duties with the

          officer, director of shareholder (other than passive investment of not
          more than five percent (5%) of the outstanding shares of, or any other
          equity interest in, any company or entity listed or traded on a
          national securities exchange or an interest in a partnership for which
          the Employee does not exercise control over investment decisions of
          such partnership) of a Person operating or selling or intending to
          operate or sell in the areas of business and within the product
          markets listed in Schedule 1 attached hereto, within the geographic
          area of the Corporation's business. Schedule I hereto shall be amended
          from time to time upon agreement by the parties hereto to take into

     b)   During the term of this Agreement and for two (2) years thereafter,

          to or for any competitor of the Company.

     c)   In the event that the Employee breaches any provisions of this Section

          entitled, without the posting of a bond or other security, to
          injunctive relief to enforce the restrictions contained herein. In the
          event that an actual proceeding is brought in equity to enforce the
          provisions of this Section 4, the Employee shall not urge as a defense
          that there is an adequate remedy at law nor shall the Corporation be
          prevented from seeking any other remedies which may be available.

5.   TERMINATION.

     a)   Death Or Retirement. The Employee's employment hereunder shall
          terminate upon his death or retirement.

     b)   Disability. If, as a result of the Employee's incapacity due to
          physical or mental illness ("Disability"), the Employee shall have
          been absent from his duties hereunder for ninety (90) consecutive
          business days, and within thirty (30) days after written Notice of
          Termination (as hereinafter defined) is given shall not have returned
          to the performance of his duties hereunder on a full-time basis, the
          Corporation may terminate the Employee's employment hereunder.

     c)   Cause. The Corporation may terminate the Employee's employment
          hereunder for "Cause". For purposes of this Agreement, "Cause" shall
          mean (i) the willful engaging by the Employee in gross misconduct
          materially injurious to the Corporation, (ii) the willful and material
          violation by the Employee of the provisions of Section 4 hereof or of
          the Proprietary Agreement, or (iii) the willful and material violation
          by the Employee of any provision of this Agreement, other than Section
          4 hereof or of the Proprietary Agreement, which is not cured by the
          Employee within fifteen (15) days after written notice thereof from
          the Corporation. For purposes of this paragraph, no act, or failure to
          act, on the Employee's part shall be considered "willful" unless done,
          or omitted to be done, by him not in good faith and without reasonable
          belief that his action or omission was in the best interest of the
          corporation. Notwithstanding the foregoing, the Employee shall not be
          deemed to have been terminated for Cause unless and until there shall
          have been delivered to the Employee a copy of a resolution, duly
          adopted by the Board of Directors at a meeting of the Board of
          Directors called and held (after five (5) days notice to the Employee
          of such meeting and an opportunity for him, together with his counsel,
          to be heard before the Board of Director at such meeting) for the
          purposes of finding that in the good faith opinion of the Board of
          Directors, the Employee was guilty of conduct set forth above in
          clauses (i), (ii) or (iii) of this Section 5(c).

     d)   Change Of Duties. Any assignment to the Employee of duties which are
          inconsistent with the Employee's status as a Vice President of
          Research and Development or are a substantial reduction in the nature
          or the status of the Employee's responsibilities may be treated by him
          as a termination pursuant to Section 5(f) hereof.

     e)   Sale Of Assets. In the event of the sale of all or substantially all
          of the Corporation, or a sale of all or substantially all of the
          assets of the Corporation, the Employee may treat his employment as
          having been terminated pursuant to Section 5(f) herein.

     f)   Other Termination By The Corporation. Notwithstanding the foregoing
          provisions, the Corporation may terminate the Employee's employment
          hereunder at any time, subject to the provisions of Section 6(d)
          hereof.

     g)   Voluntary Termination By The Employee. Notwithstanding the foregoing
          provisions, the Employee may terminate his employment hereunder at any
          time upon three month's written notice to the Corporation, subject to
          the provisions of Section 6(c) hereof.

     h)   Notice Of Termination. Any termination by the Corporation pursuant to
          paragraphs (b), (c), or (d) above or by the Employee pursuant to
          paragraph (e) above shall be communicated by a written Notice of
          Termination. For purposes of this Agreement, a "Notice of Termination"
          shall mean a notice which shall indicate the specific termination
          provisions in this Agreement relied upon and shall set forth in
          reasonable detail the facts and circumstances claimed to provide a
          basis for termination of the Employee's employment under the provision
          so indicated.

     i)   Date Of Termination. "Date of Termination" shall mean (i) if the
          Employee's employment is terminated as a result of the Employee's
          incapacity due to physical or mental illness, thirty (30) days after
          Notice of Termination is duly given (provided that the Employee shall
          not have returned to the performance of his duties on a full-time
          basis during such thirty (30) day period), (ii) the date of the
          Employee's death or retirement, or (iii) if the Employee terminates
          his employment or his employment is terminated for any other reason,
