                                   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 as
follows (the "Subadviser Fee"):



                            FIRST       EXCESS OVER
                          $1 BILLION     $1 BILLION

Real Return Bond 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.



TRUST PORTFOLIO(S)            OTHER PORTFOLIO(S)

Real Return Bond Trust   --   Real Return Bond 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 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.
