     "5. COVENANT NOT TO COMPETE.  In consideration for Executive's employment
by the Company under the terms provided in this Agreement and as a means to aid
in the performance and enforcement of the terms of the provisions of Paragraph
4, Executive agrees that:

         (a) during the Period of Employment and for a period of twelve (12)
months thereafter, regardless of the reason for termination of employment,
Executive will not, directly or indirectly, as an owner, director, principal,
agent, officer, employee, partner, consultant, servant, or otherwise, carry on,
operate, manage, control, or become involved in any manner with any business,
operation, corporation, partnership, association, agency, or other person or
entity which is engaged in a business that is directly competitive with any of
the Company's products which are produced or in development by the Company as of
the date of Executive's termination of employment, anywhere in the world;
provided, however, that the foregoing shall not prohibit Executive from owning
up to one percent (1%) of the outstanding stock of a publicly held company
engaged in activities competitive with that of the Company; and

         (b) during the term of Executive's employment with the Company and for
a period of twelve (12) months thereafter, regardless of the reason for
termination of employment, Executive will not directly or indirectly solicit or
induce any present or future employee of the Company or any affiliate of the
Company to accept employment with Executive or with any business, operation,
corporation, partnership, association, agency, or other person or entity with
which Executive may be associated, and Executive will not knowingly employ or
cause any business, operation, corporation, partnership, association, agency, or
other person or entity with which Executive may be associated to employ any
present or future employee of the Company without providing the Company with ten
(10) days' prior written notice of such proposed employment.

         Should Executive violate any of the provisions of this Paragraph, then
in addition to all other rights and remedies available to the Company at law or
in equity, the duration of this covenant shall automatically be extended for the
period of time from which Executive began such violation until he permanently
ceases such violation. "
