File number 811-8229
PaineWebber S&P 500 Index Fund
On September 30, 1998, old Class A shares (which had been renamed Class X
shares) were converted into Class Y shares. In addition, effective
October 1, 1998, new Class A and Class C shares were first offered for
sale to the public.
As they relate to the new offering and description of Class A and Class C,
incorporated by reference are the distribution contracts, 12b-1 plans and
new 18f-3 plan included in post-effective amendment No. 3 to the Fund's
registration statement (Accession Number 928385-98-002034).
