THE DISCUSSIONS ON PAGES 5 AND 19 REGARDING THE EQUITY FUND'S POLICY WITH
RESPECT TO THE VOTING OF SHARES OF THE INDEX PORTFOLIO HELD BY THE EQUITY FUND
IS HEREBY CLARIFIED AS FOLLOWS:
The Trustees of the Equity Fund have adopted the following policy with respect
to voting shares of the Index Portfolio: Whenever the Equity Fund is requested
to vote on a matter pertaining to the Index Portfolio, the Trustees of the
Equity Fund will, in their discretion and in accordance with applicable law,
either seek instructions from shareholders of the Equity Fund and vote the
shares only in accordance with such instructions, or vote the shares held by
the Equity Fund in the same proportion as the vote of all other holders of
shares in the Index Portfolio.
Whenever the Trustees determine to seek the instructions of the Equity Fund
shareholders, the Equity Fund will hold a meeting of its shareholders and, at
the meeting of investors in the Index Portfolio, the Equity Fund will cast all
of its votes in the same proportion as the votes of the Equity Fund's
shareholders. Equity Fund shareholders who do not vote will not affect the
Equity Fund's votes at the Index Portfolio meeting. Shares of the Equity Fund
for which no voting instructions have been received will be voted by the
Trustees in the same proportion as the shares for which it receives voting
instructions.
The Index Portfolio has notified the Equity Fund that the Index Portfolio is
seeking the approval of its shareholders of certain proposals to restructure
the management of the Index Portfolio, including the approval of a new
Management Agreement with a new investment adviser and a new Submanagement
Agreement. In accordance with the foregoing procedure, the Trustees have
determined that it is appropriate to vote the shares of the Index Portfolio
held by the Equity Fund which it is entitled to vote in the same proportion as
the vote of all other holders of shares in the Index Portfolio. As of August
28, 1997, the Equity Fund held 1.89% of the shares of the Index Portfolio.
