upon the terms herein.  The Aircraft  presently  owned or leased by Operator and
available for User's use are listed on the attached  Schedule A. This  Agreement
does not prohibit Operator, in its discretion, from increasing or decreasing the
number or type of Aircraft subject to this Agreement.

Aircraft is required  by User to be away from its home base of  operation.  User
shall  reimburse  Operator  for the costs of fuel and pilot  expenses at a fixed
rate  determined  by Operator to be  reasonably  allocable  to User's use of the
Aircraft  pursuant hereto.  However,  such share of allocable costs shall not in
any event exceed the costs  permitted to be charged by Operator to User pursuant
to Section  91.501(d) of the Federal Aviation  Regulations,  or any successor or
replacement regulations. Operator will invoice User for expenses as incurred and
permissible  under FAR SEC.  91.501 which will be due upon  receipt.  Payment of

its  operations,  and the  judgment of such pilot as to the  suitability  of the
