to Disability (Paragraph 8), or (c) in the case of Change of Control (Paragraph
15):

         (1) The Executive shall become vested immediately in any unvested stock
         options (other than incentive stock options under a qualified plan)
         that the Executive may have at the time of his termination; and must
         exercise all stock options within 90 days of termination or forfeit
         either all unexercised options;

         (2) To the extent, and only to the extent, that the same is permitted
         by law without thereby disqualifying any plan of the Company or an
         affiliate that is a qualified plan under the Internal Revenue Code or
         that otherwise enjoys or provides tax benefits to employees under the
         Internal Revenue Code, the Executive shall become vested immediately in
         any and all other benefits under each and every benefit plan of the
         Company or any affiliate and in which the Executive, at the time of his
         termination, had unvested benefits.

         (3) The company will indemnify and defend the Executive in the same
         manner and to the same degree as if he was an employee, executive,
         officer and director of the Company, for all litigation or other
         actions brought against the Executive originating as a result of
         association of the Executive with the Company, including but not
         limited to all claims, liability, damage, loss, expense, attorneys
         fees, court costs, judgements, settlements, fines, etc.

11. Covenant not to Compete. During the Term of Employment and for a period of

of this paragraph, the Employee will be deemed, directly or indirectly, engaged
in a business if he participates in such business as proprietor, partner, joint
venturer, stockholder, director, officer, lender, manager, employee, consultant,
advisor or agent or if he otherwise controls such business. The Employee shall
not, for purposes of this paragraph, be deemed stockholder if he holds less than
one (1%) percent of the outstanding shares of any publicly owned corporation
engaged in the same or similar business to that of the Company or any of its
divisions, subsidiaries or affiliates; provided, however, that the Employee
shall not be in a control position with regard to such corporation. In addition,
the Employee shall not be in a control position with regard to such corporation.

part, Paravant Inc., or any other name then used by the Company or any of its
affiliates or subsidiaries.

subsidiaries or affiliates; (b) a description of any of the methods of obtaining
business, or manufacturing or advertising products, or of obtaining customers
thereof; and/or (c) any

confidential information acquired by him during the course of his employment by
the Company, its predecessors, subsidiaries or affiliates, including, without
limiting the generality of the foregoing, the names of any new customers or

or shall have, traded or dealt with (whether such customers have been obtained
by the Employee or otherwise) the Company, its predecessors, subsidiaries or
affiliates.

13. Inventions. As between the Employee and the Company, all products, designs,
styles, processes, discoveries, materials, ideas, creations, inventions and
properties, whether or not furnished by the Employee, created, developed,
invented or used in connection with the Employee's employment hereunder or prior
to this Agreement, will be the sole and absolute property of the Company for any
and all purposes whatever in perpetuity, whether or not conceived, discovered
and/or developed during regular working hours. The Employee will not have, and
will not claim to have, under this Agreement or otherwise, any right, title or
interest of any kind or nature whatsoever in or to any such products, processes,
discoveries, materials ideals, creations, inventions and properties.

virtue of a sale, merger by the Company into, or the combination with, another
corporation or other form of takeover wherein the resulting entity controls
thirty-three percent (33%) or more of the voting stock, and there is more than a
50% change in the composition of the Board, then if the Employee is terminated
without cause, as contemplated in Paragraph 9, during the first one year
following the change of control, the Employee's severance benefits under Section
9 will be increased by 12 months, but in no case will the total severance exceed
2 years base salary. Further, this Employee may voluntarily resign and receive a
total severance of 2 years base salary upon acceptance of a two (2) year
covenant not to compete.

16. Further Instruments. The Employee will execute and deliver all such other
further instruments and documents as may be necessary, in the opinion of the
Company, to carry out the purposes of this Agreement, or to confirm, assign, or
convey to the Company any products, processes, discoveries, materials, ideas,
creations, inventions or properties referred to in Paragraph 12 hereof,
including the execution of all patent applications.

17. Notice. Any written notices required hereunder shall be deemed sufficient if
delivered personally or by certified mail to the Employer at its regular
business office and to the Employee at his home address on file with the

obligations hereunder, without the consent of the other party hereto. Provided,
however, that upon the sale or transfer of all or substantially all of the
assets of the Company or upon the sale, merger by the Company into, or the
combination with, another corporation or other form of takeover, this Agreement
will (subject to the provisions of Paragraph 2 hereof) inure to the benefits of

this Agreement by the other shall not operate or be constructed as a waiver of
any subsequent breach by such other party.

parties as to the subject matter hereof. It may not be changed orally, but only
by an agreement in writing signed by the party against whom enforcement of any
waiver, change, modification, extension or discharge is sought.
