elsewhere in the trade is not intended to and shall be deemed not to be a part
of the "Confidential Information".

2.   Agreement Not to Solicit Customers.  Consultant agrees that during his
engagement by Company and for a period of one (1) year following termination
of such engagement for any reason whatsoever, Consultant shall not, either
directly or indirectly, on his own behalf or in the service of or on behalf of
others actively solicit, or attempt to solicit, initiate contact with, or call
upon any clients or actively sought prospective clients of Company with whom
Consultant had material contact during his engagement with Company, for the
purpose of soliciting, selling, diverting to or otherwise providing services
on behalf of any business entity  which engages in the business of design,
manufacture or sale of information security technology.

     2.1  Material Contact.  For purposes of this Agreement, "material
contact" exists between Consultant and each client or actively sought
prospective client of Company with whom Consultant personally interacts on
behalf of Company, whether such interaction is conducted in person, in
writing, by telephone or by other form of communication.

3.   Agreement Not to Solicit Consultants.  Consultant agrees that during his
engagement by Company and for a period of two (2) years following termination
of such engagement for any reason, he will not, either directly or indirectly,

encourage or induce the voluntary termination of, or recruit or hire, or
attempt to recruit or hire, any person(s) then employed by or associated with
Company as an consultant, independent contractor or consultant, whether or not
such recruit or hire is a full-time, part-time or temporary consultant,
independent contractor or consultant of said entities, and whether or not such
engagement is for a determined period or is at-will, for the purpose of
engagement, consultancy, or serving as an independent contractor for, directly
or indirectly, any business entity which  engages in the business of design,
manufacture and sale of information security technology.

4.   Work Product.

     4.1  Consultant agrees that any inventions, ideas, Confidential
Information, or copyrightable or patentable subject matter in whole or in part
conceived or made by consultant during or after the term of his engagement
with Company which are made through the use of any of Company's Confidential
Information or any of Company's equipment, facilities or time, or which result
from any work performed by Consultant for Company (collectively, "Work
Product"), shall belong exclusively to Company and shall be considered part of
the Confidential Information (as the case may be) for purposes of this
Agreement.

use and/or to apply for patents, copyrights or other statutory or common law
protections for such Work Product in any and all countries.  Consultant shall
provide reasonable assistance to Company (at Company's expense) to obtain and
from time to time enforce patents, copyrights, and other statutory or common
law protections for such Work Product in any and all countries.  To that end,
Consultant shall execute, during and after his engagement with Company, all
documents reasonably related to the application, procurement, and enforcement
of patents, copyrights, and other statutory or common law protections, as
Company or its counsel may request, together with any assignments thereof to
Company or its designee.

<PAGE>                          2

     4.3  All copyrightable subject matter generated or developed by
Consultant under this Agreement shall be deemed to be work made for hire, and
exclusively the Company shall upon creation, own all such copyrightable
subject matter.  In the event that any such copyrightable subject matter may
not be considered work made for hire, then to the fullest extent permitted by
law, Consultant hereby assigns to Company or its designee all ownership of all
copyrights in all such copyrightable subject matter, and Company or its
designee shall have the right to obtain and hold in its own name copyrights,
registrations and similar protections related thereto to the extent available.

5.   Conflicts of Interest.     During the term of his engagement Consultant
shall not engage in activities or practices involving any possible conflict of
interest.  These activities or practices may subject Consultant to
disciplinary action, up to and including termination of engagement.
Consultant should avoid at all times the appearance of, as well as an actual,
conflict of interest.

     5.1  Conflicts of interest activities or practices include, but are not
limited to: engaging in business conduct that is damaging to the reputation of
the Company, accepting outside engagement in any organization that does
business with the Company or is a competitor of the Company, investing or
having a financial interest in a private company which does business with the
Company or having stock ownership in a publicly traded company which does
business with the Company if the relationship(s) may influence Consultant's
business decisions (this applies to Consultant and to close relatives and is
applicable at the time of hire and at any time during the course of
engagement).  If an individual does own stock in a company that does business
with the Company, the relationship should be disclosed upon engagement and all
significant business dealings with that company will be reviewed.

     5.2  Consultant may not accept gifts from any person or company doing
or seeking to do business with the Company. Consultants are allowed to accept
advertising novelties and other gifts of nominal value.

     5.3  Consultant may not give, offer, or promise, directly or
indirectly, anything of value to any representative of any company doing
business with the Company.

     5.4  Consultant may not select vendors on the basis of anything other
the merit of their products or services.

     5.5  Discussing company information with the press without prior
          authorization from management is also a conflict of interest.

     6    Outside Engagement.  Unless agreed otherwise in writing, the
Company does not expect that Consultant's full time and effort will be devoted
to Consultant's duties for the Company; in addition, the Company recognizes
that Consultant will hold outside engagement, which does not interfere with
Consultant's completion of duties owed to the Company.

     7.  MISCELLANEOUS

     7.1  Severability.  Should any provision of this Agreement be declared
or be determined by any court of competent jurisdiction to be illegal or
invalid, said court is hereby authorized and instructed to modify said
provision, if possible, so as to make said provision legal or valid; however,

of said rights; powers or remedies shall operate as a waiver thereof.  Nor
shall a waiver signed by either Party of any breach of the covenants,
conditions, or agreements binding on the other Party on one occasion be
construed as a waiver or consent to such breach on any future occasion or a
waiver of any other covenant, condition, or agreement herein contained.

this Agreement or the breach thereof shall be settled by binding arbitration

Commercial Arbitration Rules of the American Arbitration Association, and
judgment on the award rendered by the arbitrator(s) may be entered in any
court having jurisdiction thereof; provided, however, that, in the event of a

injunctive relief in any court of competent jurisdiction.  The Arbitration

performance of the Duties hereunder is located, if such city is a Qualified
