                                                       Registration No. 33-12738

                          FUNDAMENTAL FIXED-INCOME FUND
                          TAX-FREE MONEY MARKET SERIES
                         Supplement Dated April 1, 1999
                         to Prospectus Dated May 1, 1998

               The following information supplements and supersedes any contrary
information contained in the Fund's Prospectus:

               In  order  to take  advantage  of  investment  opportunities  and
increase  the  Tax-Free  Money  Market  Series'  (the  "Money  Market   Series")
flexibility  when selecting  investments,  the Money Market  Series'  investment
policy prohibiting investments in other investment companies,  except as part of
a merger, consolidation, or acquisition of assets, has been amended to permit it
to invest in other  investment  companies.  Upon  investing in other  investment
companies,  the Money  Market  Series will bear a portion of the expenses of the
underlying  fund or funds,  in  addition  to its own  expenses.  The  Investment
Company Act of 1940 (the "1940 Act")  currently  limits the amount an investment
company may invest in other investment companies.  Under these limitations,  the
Money  Market  Series  may  only  purchase  up to 3% of  the  total  outstanding
securities of any underlying fund. In addition,  an underlying fund whose shares
are purchased by the Money Market Series will be obligated to redeem shares held
by the  Money  Market  Series in an  amount  up to 1% of the  underlying  fund's
outstanding  securities during any period less than 30 days. Because of the 1940
Act  limitations,  shares held by the Money Market  Series in excess of 1% of an
underlying  fund's  outstanding   securities  will  be  considered  not  readily
marketable securities,  which together with other such securities may not exceed
10% of the Money Market Series' assets.
