         to assets that are subject to the Subadviser's investment discretion in

                  For the combined assets of:
               o  RiverSource Aggressive Growth Fund (formerly AXP Partners
                  Aggressive Growth Fund), a series of AXP Partners Series, Inc.
                  (agreement between the Fund and RiverSource Investments dated
                  January 9, 2003), and
               o  RiverSource Strategy Aggressive Fund, a series of AXP Strategy
                  Series, Inc. (agreement between the Fund and RiverSource
                  Investments dated December 1, 2002)

                  Average Daily Net Assets*                    Rate
                  -------------------------------------------------
                  First $100 million                          50 bp
                  Next $150 million                           45 bp
                  Next $250 million                           40 bp
                  Thereafter                                  38 bp

                For the combined assets of:
               o  RiverSource Small Cap Equity Fund (formerly AXP Partners Small
                  Cap Core Fund), a series of AXP Partners Series, Inc.
                  (agreement between the Fund and RiverSource Investments dated
                  December 2, 2002), and
               o  RiverSource Discovery Fund (formerly AXP Discovery Fund), a
                  series of AXP Discovery Series, Inc. (agreement between the
                  Fund and RiverSource Investments dated December 1, 2002)

                  Average Daily Net Assets*                     Rate
                  --------------------------------------------------
                  First $25 million                            65 bp
                  Next $125 million                            60 bp
                  Next $50 million                             57.5 bp
                  Thereafter                                   55 bp


         --------------------------------
         *These rates are not retroactive. When average daily net assets exceed
         the first breakpoint, multiple rates will apply, resulting in a blended
         rate, e.g. if average daily net assets RiverSource Aggressive Growth
         Fund are $125 million, a rate of 50 bp would apply to $100 million and
         a rate of 45 bp would apply to $25 million.




In witness whereof, the parties have caused this Amendment to be executed by
their officers designated below.
