Effective August 31, 1999, the paragraphs entitled "Flex Shares" on page 30 of
the Equity Funds Flex/Investor Shares Prospectus and on page 31 of the Bond
Funds Flex/Investor Shares Prospectus should be replaced with the following:

         FLEX SHARES

         You may exchange Flex Shares of any Fund for Flex Shares of any other
         Fund, or for Investor Shares of the Prime Quality Money Market Fund
         only. This is the only money market fund into which exchanges from Flex
         Shares of the bond and equity funds are permitted. No contingent
         deferred sales charge is imposed on redemptions of money market funds
         shares you acquire in an exchange, provided you hold your shares for at
         least one year from your initial purchase. If you exchange Flex Shares
         for Investor Shares of the Prime Quality Money Market Fund, you may
         only exchange those Prime Quality Money Market Fund Investor Shares for
         Flex Shares.
