                                        2



                                   APPENDIX A

     The Subadviser shall serve as investment subadviser for the following
portfolio of the Trust (the "Portfolio"). The Adviser will pay the Subadviser,
as full compensation for all services provided under this Agreement, the fee
computed separately for the Portfolio at an annual rate as follows (the
"Subadviser Percentage Fee"):



PORTFOLIO             ALL ASSET LEVELS
---------             ----------------
                   
Special Value Trust


     The Subadviser Percentage 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. 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
rate described in the preceding paragraph, and multiplying this product by the
net assets of the Portfolio as determined in accordance with the Trust's
prospectus and statement of additional information as of the close of business
on the previous business day on which the Trust was open for business.

     If 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, 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 occurs.
