     that such confidential and highly sensitive information constitutes either
     a Trade Secret or Confidential Information, and Executive acknowledges and
     agrees not to disclose such confidential and highly sensitive information

     Company.

5.2  As used herein: "Trade Secret" shall mean any technical or scientific
     information, design, process, procedure, formula or improvement, or any
     portion or phase thereof, whether or not patentable, that is of value to

     Company's business methods. Confidential Information also includes any
     information described above which the Company obtains from another Party
     and which the Company treats as proprietary or designates as Confidential
     Information. Confidential Information does not include any of the foregoing
     items if they become publicly known and/or are made generally available by
     Company through no wrongful act of Executive or by others who were under
     confidentiality obligations.

5.4  Executive will not discuss the existence of this Agreement or the terms
     contained herein, with any employee, contractor or agent of Company, except
     Executive will be free to discuss this Agreement with the his/her direct

                             SECTION 6 - INVENTIONS

6.1  Executive agrees to promptly disclose to the Company any and all
     inventions, discoveries, improvements, trade secrets, formulas,
     compositions, code, designs, programs, techniques, processes, and know-how,
     whether or not reduced to writing or practice, conceived by Executive
     during the period of his employment, either alone or jointly with others,
     which relate to or result from the actual or anticipated business, work,
     research or investigations of the Company, or which result from use of the
     Company's premises or property (the work being hereinafter collectively
     referred to as the "Intellectual Property"). Further, Executive shall
     disclose in confidence to the Company


                                       4
<PAGE>

     all patent and copyright applications filed by or on behalf of Executive
     during the term of his employment and, to the extent such application
     relates to the Intellectual Property of the Company at the date Executive's
     employment terminates, for a period of twelve (12) months thereafter.

6.2  Executive acknowledges and agrees that during the term of this Agreement
     and as further provided herein, all the Intellectual Property will be the
     sole property of the Company or any other entity designated by it, and
     Executive hereby assigns to the Company the Executive's entire right and
     interest in and to all Intellectual Property. Executive further agrees as
     to all Intellectual Property to reasonably assist the Company (at the
     Company's expense) to obtain and from time to time enforce patents and
     copyrights on the Intellectual Property in any and all countries during the
     term of this Agreement. To that end, by way of illustration but not
     limitation, Executive will testify in any suit or other proceeding
     involving any of the Intellectual Property, execute all documents which the
     Company reasonably determines to be necessary or convenient for use in
     applying for and obtaining patents and copyrights thereon and enforcing
     same, and execute all necessary assignments thereof to the Company or
     persons designated by it.

6.3  Executive's obligation to assist the Company in obtaining and enforcing
     patents and copyrights for the Intellectual Property shall continue beyond
     the termination of his employment, but the Company shall compensate
     Executive at a reasonable rate after such termination for the time actually
     spent by Executive at the Company's request on such assistance and the
     Company's requests for assistance shall be reasonable in light of
     Executive's then existing commitments.

6.4  Executive hereby irrevocably appoints the Company, and its duly authorized
     officers and agents, as Executive's agent and attorney-in-fact to act for
     and on behalf of Executive in filing all patent and copyright applications,
     amendments, renewals, and all other appropriate documents in any way
     related to Intellectual Property. The Company will promptly notify
     Executive following any such filing, provided that the Company will not be
     obligated to make such notification if as a result the Company would be in
     violation of any agreement or order to which it is subject or bound.

6.5  For the purposes of this Agreement, an invention or other Intellectual
     Property is deemed to have been made or conceived during the duration of
     employment if during such time, the invention or other Intellectual
     Property was conceived or first actually reduced to writing or practice.

                              SECTION 7 - REMEDIES

7.1  In the event that Executive violates any of the provisions set forth in
     Sections 4 through 6 of this Agreement relating to responsibilities,
     nondisclosure or inventions, Executive acknowledges and agrees that the
     Company could suffer immediate and irreparable harm, which cannot be
     accurately calculated in monetary damages. Consequently, Executive
     acknowledges and agrees that the Company shall be entitled to seek
     injunctive relief, either by temporary or permanent injunction, to prevent
     such a violation. Executive


                                       5
<PAGE>

     acknowledges and agrees that this injunctive relief shall be in addition to
     any other legal or equitable relief to which the Company would be entitled.

7.2  In the event that the Parties to this Agreement fail to agree on the one or
     more of the clauses incorporated in this Agreement, both Parties agree to
     attempt to resolve this disagreement amicably by direct negotiations
     between Executive and the Board. If such attempts to resolve any
     disagreement have not been successful after a period of thirty (30) days,
     then the Parties agree to submit the disagreement to a mutually agreeable
     mediator, with the costs of such mediation services being shared equally by
     the Parties.

                        SECTION 8 - TERM AND TERMINATION

8.1  This Agreement will become effective as of the date hereof, and will expire

     Compensation that has been previously awarded to Executive from a previous
     fiscal year but not actually paid by Company.

     Agreement, Executive may terminate this Agreement, within ninety (90) days
