                                   APPENDIX A

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



                                          BETWEEN
                           FIRST       $500 MILLION    EXCESS OVER
PORTFOLIO              $500 MILLION   AND $1 BILLION    $1 BILLION
---------              ------------   --------------   -----------
                                              
All Cap Growth Trust


     For purposes of determining net assets or aggregate 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, and the net assets of each portfolio
of each other fund are determined as of the close of business on the previous
business day of that fund.

     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 any Portfolio, this Agreement becomes effective or
terminates, or the portfolios to be included for purposes of determining
aggregate net assets changes, 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.
