                  requests extraordinary services (e.g., obtaining debt or
                  equity financing or coordinating or negotiating the
                  consummation of acquisitions or divestitures), additional fees
                  may be charged pursuant to arrangements to be mutually agreed
                  upon by the Company and KECC.

         (b)      The services provided pursuant to this Agreement are advisory
                  only and the Company is free to accept or reject the advice

3.       COMPENSATION.

         (a)      The Company agrees to pay to KECC as compensation for
                  services to be rendered by KECC hereunder, a fee based
                  upon the number of hours of service rendered by KECC at

         directors, officers and employees in connection with the
         rendering of services hereunder.  Such expenses shall be in
         addition to any Advisory Fees and shall not affect the
         maximum amount of Advisory Fees payable pursuant to
         paragraph 3 above.
