                  plans, an amount equal to the vested benefits of the Employee
                  in any pension or other benefit plan as of the termination

                  13. Restrictive Covenants.

                           13.1. Employee understands that the Company's
                  business involves the design, improvement, development,
                  testing, manufacturing, marketing and sale


                                      -4-
<PAGE>   5
                  of products, and that this business requires substantial
                  investments in capital and substantial commitments of time and
                  effort by the Company's employees. The Employee further
                  understands that, as a result, certain of the Company's
                  personnel, including the Employee, acquire information with
                  respect to customer goodwill, trade secrets and Confidential
                  Information, which, of itself and apart from the Employee's
                  abilities, could be of great value to a competitor of the
                  Company, potential competitors of the Company, and to others.

                           13.2. The Employee further understands that
                  employment with the Company is conditioned upon the Company's
                  being able to place complete trust and confidence in the
                  Employee and to rely on the Employee's doing everything
                  possible to avoid the disclosure or use of Confidential
                  Information to persons, corporations, organizations and others
                  outside the Company, which may become known to, or subject to
                  the control of the Employee during the term of employment
                  hereunder. The Employee also understands that competition in
                  the manufacture, sale, and development of products is not
                  local in nature or scope, but involves various corporations,
                  organizations and others located within the United States and
                  throughout the world.

                           13.3. In recognition of these circumstances and for
                  the purpose of inducing the Company to employ the Employee (or
                  continue the employment of the Employee with appropriate
                  compensation reviews) to repose trust and confidence in the
                  Employee, and to make Confidential Information available to
                  the Employee, the Employee agrees that the following
                  restrictive covenants are necessary and proper for the
                  protection of the Company.

                           13.4. Subject to Section 13.6 below, the Employee
                  will promptly disclose and assign to the Company, without the
                  right to any form of compensation therefore, every invention
                  that the Employee, individually or jointly with others, during
                  the term of the Employee's employment with the Company and for
                  a period of one (1) year following termination of such
                  employment for any reason, may discover, invent, conceive or
                  originate, relating in any way to the present or contemplated
                  scope of the Company's business with regard to any of its
                  clients, customers or vendors or to any Product, Technology,
                  process, or device dealt in, used or under development or
                  manufacture by the Company for itself or others or that
                  results from or may be suggested by any work the Employee may
                  do for the Company or at the Company's request. The Employee
                  will fully cooperate with the Company in applying for and
                  securing in the name of the Company or its designee patents or
                  copyrights with respect to said Inventions in each country in
                  which the Company may desire to secure patent or copyright
                  protection. The Employee will promptly execute all proper
                  documents presented to the Employee for signature by the
                  Company to enable the Company or its designee to secure such
                  patent or copyright protection and to transfer legal title
                  therein, together with any patents or copyrights that may be
                  issued thereon or in connection therewith, to the Company or
                  its designee. The 


                                      -5-
<PAGE>   6
                  Employee will give such true information and testimony as may
                  be requested of the Employee by the Company relative to any of
                  said Inventions.

                           13.5. Subject to Section 13.6 below, the Company
                  shall have the exclusive right to use in its business, and to
                  make, use and sell products, processes, and/or services
                  arising out of any Invention, whether or not patentable, which
                  is assignable by the Employee to the Company pursuant to
                  Section 13.4 above.

                           13.6. The Employee is hereby notified that Sections
                  13.4 and 13.5 above do not apply to an Invention for which no
                  equipment, supplies, facility, technology, confidential
                  information, or trade secret information of the Company was
                  used and which was developed entirely on the Employee's own
                  time, unless:

                                    13.6.1. The Invention was related:

                           the Company or its Affiliates anywhere in the world.

                  If any court shall finally hold that the time, territory or
                  any other provision of this Section 13.9 constitutes an
                  unreasonable restriction against the Employee, the Employee
                  agrees that the provisions hereof shall not be rendered null
                  and void, but shall apply as to such time, territory, and
                  other extent as such court may determine to be a reasonable
                  restriction under the circumstances involved.

                  breach by the Employee of any duty to the Company with respect
                  to any Confidential Information or Invention, the Company may
                  suffer irreparable injury and may not have adequate remedy at
                  law. As a result, the Employee agrees that if a breach of this
                  Agreement occurs, the Company may, in addition to any other
                  remedies available to it, bring an action or actions for
                  injunction, specific performance, or both, and have entered
