in the table above has been restated to reflect the current fees. Prior to
April 30, 1999, the investment adviser, Morgan Stanley Dean Witter Advisors
Inc., assumed all expenses of the Portfolio and waived the compensation
provided for the Portfolio in its management agreement with the Fund.

Markets Equity, and Emerging Markets Debt Portfolios, the investment

to reimburse the Portfolios for certain
<PAGE>
other expenses. Absent such reductions, it is estimated that "Management
