                                   APPENDIX A

     The Subadviser shall serve as investment subadviser for the 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 the
Portfolio, the fee computed separately for the Portfolio at an annual rate as
follows (the "Subadviser Fee"):



                                     FIRST           EXCESS OVER
                                $500 MILLION OF     $500 MILLION

PORTFOLIO                            ASSETS            ASSETS
---------                       ---------------   ----------------
                                            
Global Asset Allocation (1)           [_]%              [_]%


*    The term Aggregate Net Assets for a given day includes the net assets of
     the Portfolio of the Trust. It also includes the net assets of one or more
     other portfolios of the Trust or other trusts as indicated below, but in
     each case only for the period during which the Subadviser for the Portfolio
     also serves as the subadviser for the other portfolio(s). For purposes of
     determining Aggregate Net Assets and calculating the Subadviser Fee for a
     given day, the net assets of the Portfolio and each other portfolio of the
     Trust are determined by the Custodian 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 or trust are determined as of the close of business on the
     previous business day of that fund.



Trust Portfolio(s)              Other Portfolio(s)
------------------              ------------------
                             
Global Asset Allocation Trust   -- Global Asset Allocation Fund, a series of
                                   John Hancock Funds II


     The Subadviser Fee for a Portfolio shall be based on the applicable annual
fee rate for the Portfolio which for each day shall be equal to (i) the sum of
the amounts determined by applying the annual percentage rates in the table to
the applicable portions of Aggregate Net Assets divided by (ii) Aggregate Net
Assets (the "Applicable Annual Fee"). The Subadviser Fee for the 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, 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 the Portfolio, this Agreement becomes effective or
terminates, or if the manner of determining the Applicable Annual Fee Rate
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.
