INVESTOR CLASS AND INSTITUTIONAL CLASS
DATED DECEMBER 1, 1997
The paragraph under the heading "Portfolio Turnover" on page 5 of the
Investor Class Prospectus and page 5 of the Institutional Class Prospectus is
deleted and replaced with the following paragraph:
"The Fund retains the right to sell securities irrespective of
how long they have been held. The Adviser estimates that the annual
turnover in the Fund will not exceed 150%. High Portfolio turnover
(100% or more) will generally result in higher transaction costs and
may result in the realization of short-term capital gains that are
taxable as ordinary income."
