number of companies known as Mellon Financial Services Corporations. Through
its subsidiaries, Mellon managed more than $130 billion in assets as of July
31, 1994, including approximately $6 billion in mutual fund assets. As of

series to (i) borrow money from banks only for temporary or emergency (not

(CONTINUED ON REVERSE SIDE)
IV. REVISED MANAGEMENT POLICIES
THE FOLLOWING INFORMATION SUPPLEMENTS AND SHOULD BE READ IN
CONJUNCTION WITH THE SECTION IN THE FUND'S PROSPECTUS ENTITLED "DESCRIPTION
OF THE FUND--MANAGEMENT POLICIES."
BORROWING MONEY -- As a fundamental policy, each series is permitted
to borrow from banks only for temporary or emergency (not leveraging)
purposes, in an amount up to 15% of the value of the series' total assets
(including the amount borrowed) valued at the lesser of cost or market, less
liabilities (not including the amount borrowed) at the time the borrowing is
made. While borrowings exceed 5% of a series' total assets, such series will
not make any additional investments.
ILLIQUID SECURITIES -- Each series may invest up to 10% of the value
of its net assets in securities as to which a liquid trading market does not
exist, provided such investments are consistent with the series' investment
objective. Such securities may include securities that are not readily
marketable, such as certain securities that are subject to legal or
contractual restrictions on resale and repurchase agreements providing for
settlement in more than seven days after notice. As to these securities, the
series are subject to a risk that should the series desire to sell them when
a ready buyer is not available at a price the series deems representative of
their value, the value of the series' net assets could be adversely affected.
