                                   APPENDIX A

     The Subadviser shall serve as investment subadviser for each Portfolio of

Capital Appreciation Trust*


*    The term Aggregate Net Assets includes the net assets of a Portfolio of the
     Trust. It also includes with respect to each Portfolio the net assets of
     one or more other portfolios 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, the net assets of
     the Portfolio and each other 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, in each case
     based on market values as reported by the Trust's custodian.



Trust Portfolio(s)                              Other Portfolio(s)

Capital Appreciation Trust    --   Capital Appreciation 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 the quotient of
(i) the sum of the amounts determined by applying the annual percentage rates in
the table to the applicable portions (as determined by percentage rate
breakpoints) of Aggregate Net Assets divided by (ii) Aggregate Net Assets (the
"Applicable Annual Fee Rate"). 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 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.
