         hereunder may be terminated by the Company at any time for Cause. Such

         hereunder  shall  terminate  in  the  event  of  Employee's   death  or
         Disability (as defined in Section 11).

             (d)   Notwithstanding the foregoing,  the Employee's  employment
         hereunder may be terminated by the Company at any time without Cause.
         Such termination shall be effective upon the Company providing written
         notice to the Employee as to the effective date of termination.

             (e)   Notwithstanding the foregoing,  the Employee's  employment
         hereunder may be terminated by the Employee at any time for Good Reason
         (as defined in Section 11) upon prior written notice to the Company

         of termination.

             (f)   In  addition  to  all  other   rights  of  Employee   and
         obligations of the Company described herein which arise or continue
         upon termination of Employee's employment, the following shall apply:

                   (i)    Upon  termination  of the  Employee's  employment
             hereunder for any reason whatsoever, the Company shall pay to
             the Employee all salary and benefits earned through the
             effective date of termination.

                   (ii)   If  the  Employee's   employment  hereunder  is
             terminated by the Company without Cause or by the Employee for
             Good Reason, the Employee shall be entitled to receive, as
             Employee's sole remedy for such termination, the Base Salary
             through the end of the 12 month period immediately following
             the effective date of such termination of Employee. If the
             Employee's employment is terminated by the Company without
             Cause, then all salary owed to the Employee shall be paid over
             the relevant period of time in accordance with the Company's
             normal payroll practices. Notwithstanding the foregoing, in
             order to be eligible for the payments contemplated by this

             terms of Sections 9 and 10 and the Employee must deliver a
             complete release of all claims in favor of the Company and in
             a form satisfactory to the Company.

                   (i)    engage in any  business  that  competes  with the
             business of the Company ("Company" defined in Sections 9, 10
             and 11(b) herein to mean all Subsidiaries, Affiliates,
             divisions, successors, and assigns of the Company and any of
             their Subsidiaries or Affiliates) anywhere within the United
             States and such other countries that the Company is then
             conducting its business; provided, however, that the foregoing
             shall not prohibit the Employee's ownership of up to 1% of the
             outstanding shares of capital stock of any corporation whose
             securities are publicly traded on a national or regional stock
             exchange;

                   (ii)   purposefully  interfere or attempt to interfere
             with any of the Company's contracts (regardless of whether
             these contracts are in writing or verbal) or business
             relationships or advantages existing and in effect as of the
             effective date of termination of this Agreement;

                   (iii)  solicit  for  employment,  either  directly or
             indirectly, for himself or for another, any of the technical or
             professional employees who are or were employed by the Company
             during the two-year period following the termination of this
             Agreement; and

                   (iv)   purposefully   interfere   with  the  business
             relationship of or solicit the business or orders of Persons
             (a) who are Company customers on the effective date of
             termination of this Agreement, or one year prior thereto, or
             (b) a prospective or potential customer of the Company, except
             that with respect to the two-year period following the
             effective date of termination of this Agreement, such
             restriction shall apply only to prospective or potential
             customers (1) to whom the Company has submitted a formal
             quotation within the one year prior to the effective date of
             termination of this Agreement, or (2) that have been
             previously listed or identified by the Company as a business
             prospect at any time during the six months preceding the
             effective date of termination.

             (b)   The  parties  agree  that  if  the  Employee  commits  or
         threatens to commit a breach of the covenants of this Section 9, the
         Company shall have the right to seek and obtain all appropriate
         injunctive and other equitable remedies therefor, in addition to any
         other rights and remedies that may be available at law, it being
         acknowledged and agreed that any such breach would cause irreparable
         injury to the parties and that money damages may not provide an
         adequate remedy therefor.

         10. Protection of Confidential Information and Trade Secrets of the
             ---------------------------------------------------------------
Company.
-------
             (a)   Confidentiality. During the term of this Agreement and for
         a period of five years after any termination or expiration thereof, the
         Employee agrees that the Employee will not use for the Employee or
         others or divulge or convey to others any secret or confidential
         information, knowledge or data of the Company obtained by the Employee
         during his employment with the Company. Such information, knowledge or
         data includes but is not limited to secret or confidential matters: (i)
         of a technical nature such as, but not limited to, methods, know-how,
         formulae, compositions, processes, discoveries, machines, inventions,
         intellectual property, computer programs and similar items or research
         projects; (ii) of a business nature such as, but not limited to,
         information about the cost, purchasing, profits, markets, sales or
         customers; and (iii) pertaining to future developments such as, but not
         limited to, research and development, future marketing or merchandising
         plans and future expansion plans. The term "secret or confidential
         information, knowledge or data" shall not be deemed to include
         information that is published, information that is generally known
         throughout the industry, or which generally is available to the
         industry without restriction through no fault of the Employee.

             (b)   Injunctive  Relief. The Employee agrees that the Company's
         remedies at law for any breach or threat of breach by him of the
         provisions of paragraph (a) of this Section 10 will be inadequate, and
         that the Company shall be entitled to an injunction or injunctions to
         prevent breaches of the provisions of paragraph (a) of this Section 10
         and to enforce specifically the terms and provisions thereof, in
         addition to any other remedy to which the Company may be entitled at
         law or equity.

             (c)   Return  of  Documents  and  Other   Property.   Upon  the
         termination of the Employee's employment with the Company, or at any
         time upon the request of the Company, the Employee shall deliver to the
         Company (i) all documents and materials containing secret or
         confidential information, knowledge or data relating to the Company's
         business and affairs, and (ii) all documents, materials and other
         property belonging to the Company, which in either case are in the
         possession or under the control of the Employee.

             (d)   Intellectual  Property Rights.  Employee  acknowledges and
         agrees that in consideration for his employment with Company and in
         exchange for the consideration to be paid to Employee in connection
         with such employment, all creative works Employee produces in
         connection with his employment by Company which relate to Company's
         actual or demonstrably anticipated research or development, including,
         without limitation, any invention, formula, pattern, compilation,
         computer program (and related documentation and source code), device,
         method, technique, drawing, process or other intellectual property or
         property right (collectively, "Intellectual Property"), shall be
         considered to have been prepared for Company as a part of and pursuant
         to Employee's employment with Company. Employee shall disclose to
         Company the existence of such Intellectual Property when he becomes
         aware of its existence, and Employee agrees that any such Intellectual
         Property shall be owned by Company regardless of whether it would
         otherwise be considered a work made for hire. Employee agrees to
         execute any documents which Company deems necessary to protect

<PAGE>

         Company's interest, including assignments, and further agrees to give
         evidence and testimony and take any other reasonable actions as may be
         necessary, to secure and enforce Company's rights.

                   Notwithstanding  anything set forth in this  Section  10(d)
         to the contrary, the parties acknowledge and agree that any
         Intellectual Property that Employee (i) has developed or was in the
         process of developing prior to the Effective Date or which he develops
         during the Term, and (ii) has not used any of Company's resources
         (whether materials, equipment, supplies, or other employees,
         contractors or consultants of Company) in connection with such
         development, shall be owned by Employee (the "Employee Intellectual
         Property"); provided, however, Employee shall promptly notify (the
         "Development Notice")Company of the existence of such Employee
         Intellectual Property. The Development Notice shall completely describe
         the Employee Intellectual Property and the applications for such
         Employee Intellectual Property. If within 30 days after Company's
         receipt of the Development Notice Company notifies Employee that
         Company would like to purchase or license the item of Employee
         Intellectual Property which is the subject of the Development Notice,
         then Company and Employee shall negotiate in good faith for the
         purchase or license of such item of Employee Intellectual Property.
         Employee agrees that he will not directly or indirectly disclose the
         existence of the Employee Intellectual Property to any third party
         unless Company either notifies Employee in writing that Company does
         not elect to purchase or license the Employee Intellectual Property or
         Company fails to notify Employee of its intent with regard to the
         purchase or license of the Employee Intellectual Property within 30
         days after the date of Company's receipt of the Development Notice.

         to have occurred if Employee is, by agreement or understanding (written
