3. The first two paragraphs, including all of the bullet points therein, in
the section titled "How to Exchange Shares," are deleted in their entirety and
replaced by the following:

As stated in the Prospectus, shares of a particular class of Oppenheimer
funds having more than one class of shares may be exchanged only for shares of
the same class of other Oppenheimer funds. Shares of Oppenheimer funds that have
a single class without a class designation are deemed "Class A" shares for this
purpose. The prospectus of each of the Oppenheimer funds indicates which share
class or classes that fund offers and provides information about limitations on
the purchase of particular share classes, as applicable for the particular fund.
You can also obtain a current list showing which funds offer which classes of
shares by calling the Distributor at the telephone number indicated on the front
cover of this SAI.

The Fund may amend, suspend or terminate the exchange privilege at any
time. Although the Fund may impose those changes at any time, it will provide
you with notice of the changes whenever it is required to do so by applicable
law. It may be required to provide 60 days' notice prior to materially amending
or terminating the exchange privilege, except in extraordinary circumstances.
