case incidental to your employment by the Company and which are not adverse or
in conflict with the interests of the Company, its business or prospects,
financial or otherwise.
                  5.2      Except as permitted by Section 5.3, you will not

Company will not conflict with and will not be constrained by any prior
employment or consulting agreement or relationship, and that the use of any
skills and knowledge that you may have by the Company are not in violation of
the terms of any contract to which you are a party or any other applicable
provisions of the law. Subject to Section 6.2, you represent and warrant that
you do not possess confidential information arising out of prior employment
which, in your best judgment, would be utilized in connection with your
employment by the Company in the absence of Section 6.2.

you should find that confidential information belonging to any former employer

information belonging to any of your former employers; but during your
employment by the Company you will use in the performance of your duties all
information which is generally known and used by persons with training and
experience comparable to your own and all information which is common knowledge
in the industry or otherwise legally in the public domain.

business product and marketing plans, and customer information (collectively,
"Confidential Information"). You agree not to use or disclose the Confidential
Information to any third party (or cause such use or disclosure), except as
necessary to perform the duties assigned to you by the Company hereunder and in
furtherance of the best interests of the Company, or as may otherwise be
authorized in writing by the Company, Confidential Information shall not include
information which (i) is or hereafter becomes publicly known through no fault of
yours or (ii) is lawfully disclosed to you by a third party having a right to
disclose such information.
         8.       PROPRIETARY INFORMATION AND INVENTIONS. You have previously
executed, and hereby acknowledge that you are bound by the provisions of, a
Proprietary Information and Inventions Agreement with the Company.
                  9.1      You acknowledge and agree that as a result of, among
other things, (i) your access to significant and valuable Confidential
Information (as defined in Section 7 above) of the Company and (ii) the
lucrative world-wide market for the Company's expertise, services, products and
technology, the restrictions contained in this Section 9 are reasonable in all
respects and necessary to protect the Company's investments in your training and
in the Company's good will and other business interests.

and of the payments to be made to you by the Company pursuant to this Agreement,

the Company you will not directly or indirectly:
         (a)      engage in activities (similar or reasonably related to those
in which you shall have engaged during the 12 months immediately preceding the
termination of your employment with the Company) for, nor render services
(similar or reasonably related to those which you shall have rendered hereunder
during such 12 months) to, any firm or business organization which directly
competes with the Company in any line of business engaged in by the Company (or
which the Company's Board formally resolved during your employment to be engaged
in), whether now existing or established during your employment, nor shall you
engage in such activities nor render such services to any other person or entity
engaged or about to become engaged in such activities to, for, or on behalf of,
any such firm or business organization:
                  (i)      in connection with the sale, marketing or promotion
         to any customer of the Company upon whom you have called or in whose
         account you participated or
         supervised on behalf of the Company during the year prior to the
         termination of your employment with the Company, or
                  (ii)     with respect to any product, process, or service, in
         existence or under development which substantially resembles or
         competes with a product, process, or service of the Company in

         supervisory responsibility at any time during the year prior to the
         termination of your employment with the Company;
         (b)      solicit employees of the Company to leave its employ;

employed by the Company at any time during the six months prior to the

activities of the Company.
                  9.3      Upon your written request to the Company specifying
the activities proposed to be conducted by you, the Company may in its
discretion give you written approval(s) to personally engage in any activity or
render services referred to in Section 9.2 upon receipt of written assurances
(satisfactory to the Company and its counsel) from you and from your prospective
employer(s) that the integrity of the provisions of Sections 7, 8 and 9 will not
in any way be jeopardized or violated by such activities, provided the burden of
so establishing the foregoing to the satisfaction of the Company and said
counsel shall be upon you and your prospective employer(s).
         10.      REMEDIES. Your duties under Sections 7, 8, and 9 shall survive
termination of your employment with the Company. You acknowledge that a remedy
at law for any breach or threatened breach by you of the provisions of the
Sections 7, 8, or 9 would be inadequate and you therefore agree that the Company
shall be entitled to injunctive relief in case of any such breach or threatened
