indirect Subsidiaries.

counsel) arising as a result or in connection with this Agreement, the
Consultant's services hereunder or other activities on behalf of the Company and
its direct and indirect Subsidiaries.

         9. Any payments paid by the Company under this Agreement shall not be
subject to set-off and shall be increased by the amount, if any, of any taxes
(other than income taxes) or other governmental charges levied in respect of
such payments, so that the Consultant is made whole for such taxes or charges.

         10. (a) This Agreement sets forth the entire understanding of the
parties with respect to the Consultant's rendering of services to the Company.
