     The Subadviser  shall serve as investment  subadviser for the Portfolios of
the  Trust  listed  below.  The  Adviser  will  pay  the  Subadviser,   as  full
compensation for all services  provided under this Agreement with respect to the
Portfolios,  the fee computed  separately  for each such  Portfolio at an annual
rate stated as a percentage  of current net assets as follows  (the  "Subadviser
Fee"):



                                                                           
                                           First          Between $250 million      Excess Over
Portfolio                            $250  million          and $500 million        $500 million
American Fundamental Holdings Trust

American Global Diversification
Trust


     For purposes of determining net assets, the net assets of each Portfolio of
the Trust are  determined  as of the close of business on the previous  business
day of the Trust.

     The Subadviser  Fee for each  Portfolio  shall be accrued for each calendar
day,  and the sum of the  daily  fee  accruals  shall  be  paid  monthly  to the
Subadviser  within  30  calendar  days of the end of each  month.  The daily fee
accruals will be computed by multiplying  the fraction of one over the number of
calendar days in the year by the  applicable  annual fee rate,  and  multiplying
this  product by the net assets of the  Portfolio.  The  Adviser  shall  provide
Subadviser with such information as Subadviser may reasonably request supporting
the  calculation of the fees paid to it hereunder.  Fees shall be paid either by
wire transfer or check, as directed by Subadviser.

     If, with respect to each  Portfolio,  this Agreement  becomes  effective or
terminates before the end of any month, the fee (if any) for the period from the
effective  date to the end of such month or from the  beginning of such month to
the date of  termination  or from the  beginning  of such month to the date such
change, as the case may be, shall be prorated  according to the proportion which
such period bears to the full month in which such  effectiveness  or termination
or change occurs.
