    Protection of Computer Systems and SoftwareI agree to take all necessary precautions to protect the computer systems and software

    Non-CompetitionI agree that while I am employed by the Company, and for twelve months following the
termination of my employment with the company, without the prior written approval of the
Board of Directors of the Company, I will not become engaged, directly or indirectly as an
employee, consultant, partner, principal, agent, proprietor, shareholder (other than a
holding of shares listed on a stock exchange that does not exceed 2% of the outstanding

products.10.
    
    Reasonableness of Non-Competition and Non-Solicitation ObligationsI confirm that the obligations in Sections 6, 7 and 8 are fair and reasonable given that,
among other reasons,(i) the sustained contact I will have with the clients of the Company will expose me to
Confidential Information regarding the particular requirements of these clients and the
Companys unique methods of satisfying the needs of these clients, all of which I agree not to
act upon to the detriment of the Company; and/or(ii) I will be performing important development work on the software owned or marketed by
the Company, and I agree that the obligations in Sections 6, 7 and 8, together with my other
obligations under this Agreement, are reasonably necessary for the protection of the Companys
proprietary interests. I further confirm that the geographic scope of the obligation in
Section 6 is reasonable given the international nature of the market for the products and
services of the Company. I also agree that the obligations in Sections 6, 7 and 8 are in
addition to the non-disclosure and other obligations provided elsewhere in this Agreement. I
also acknowledge that my obligations contained in this Agreement will not preclude me from
becoming gainfully directly employed in the computer software industry or applicable product
training following a termination of my employment with the Company given my general knowledge
and experience in the computer industry.

employee of the Company shall not breach any agreement or other obligation to

not be employed by, or perform services for, or otherwise be engaged in any

for any breach of my obligations contained in this Agreement, and accordingly I agree that in
