     1.  Purpose and Scope

         DEFS Assets hereby retains Contractor to perform consulting services
         with regard to DEFS Assets' interests and businesses and such other
         consulting services as may be mutually agreed in writing.

     2.  Term

         a.    This Contract shall commence on April 1, 2000 and shall terminate
               on June 30, 2002, unless extended by written agreement of the
               parties.

         b.    In the event of Contractor's inability to perform his obligations
               under this Contract to the satisfaction of DEFS Assets due to
               Contractor's extended illness or death, DEFS Assets may terminate
               this Contract upon giving thirty (30) days' written notice to
               Contractor or his legal representative.

         c.    Should Contractor knowingly fail to follow the policies and
               practices of DEFS Assets in the performance of duties under this
               Contract, DEFS Assets shall provide Contractor with thirty (30)

               terminate this Contract upon thirty (30) days' written notice to
               Contractor.

         equal or greater responsibility designated by DEFS Assets.

     4.  Independent Contractor Status

         Contractor shall be an independent contractor and the remuneration
         paid hereunder shall not affect any employee or retirement benefits to
         which he may be entitled by virtue of his past employment by Parent
         Company subsidiary or affiliate.

     5.  Compensation

         a.    DEFS Assets shall pay Contractor a retainer of Forty-Six Thousand
               Eight Hundred Sixty and No/100 Dollars ($46,860) per calendar

               the event contractor performs services on more than such 30
               calendar days, DEFS Assets shall, upon receipt of an invoice as

         of J.W. Mogg, DEFS Assets shall reimburse Contractor for any
         reasonable expenses incurred in connection with services performed
         under this Contract; provided, however, that such reasonable expenses
         shall not include the cost of commuting to and from home in order to
         perform work under this Contract. Contractor shall be reimbursed for
         car expense at the standard mileage rate set by the United States
         Internal Revenue Service. Contractor hereby warrants that he has the
         legally required insurance on any motor vehicle that he would use in
         the performance of duties under this Contract.

     7.  Invoices

         Within a reasonable time after the last day of the calendar quarter,
         Contractor shall submit an invoice to DEFS Assets setting forth the

         paragraph 5.b of this agreement, the services performed, and eligible
         expenses incurred as defined in paragraph 6.

     8.  Prioritization of Work

         It is understood that Contractor is free to render consulting services
         to others so long as such activity does not conflict with the interest
         of DEFS Assets or any of its subsidiaries or affiliates. To the extent
         practicable, however, Contractor agrees to give first priority to the
         performance of services for DEFS Assets and Parent Company under the

         extension thereof. Contractor further agrees to return to DEFS Assets
         any and all information received by Contractor in performing services
         under this Contract at the termination of this Contract or when
         requested to do so by DEFS Assets.

     10. Assignment

         None of the rights or obligations of this Contract may be assigned
         without the prior written consent of the assigning party.

         IN WITNESS WHEREOF, this AGREEMENT executed this 1st day of
         April, 2000.
