second paragraph under the caption is revised in its entirety to read as
follows:
"In general, Class S shares are available for new investments by certain
large institutions, advisory accounts of the Investment Manager, and
employee benefit plans which acquire shares through programs or products
sponsored by Metropolitan Life Insurance Company ("Metropolitan") and/or its
affiliates, for which Class S shares have been designated. In addition,
Class S shares are available through special programs under which, for
example, investors pay an asset-based fee and/or a transaction fee to
intermediaries. Class S share availability is determined by the Distributor
and intermediaries based on overall direct and indirect costs of a
particular program, expected assets, account sizes and similar
considerations. Information on the availability of Class S shares and
further conditions and limitations is available from the Distributor."
Throughout the Prospectus, references to Class C shares (now redesignated
as Class S) should be read to give effect to the above revisions regarding the
availability of such shares.
