                             Supplement dated October 22, 2007
                           to the Prospectus dated July 27, 2007

This  supplement  amends the  Prospectus  dated July 27, 2007 and  supersedes the supplement
dated August 10, 2007.

The Prospectus is revised as follows:

1.    The section titled "Class A Contingent Deferred Sales Charge" on page 41, is deleted
   in its entirety and replaced with the following:

     Class A Contingent Deferred Sales Charge. There is no initial sales charge on
     Class A share purchases totaling $1 million or more of one or more of the
     Oppenheimer funds. However, Class A shares of a Fund purchased on or after
     October 22, 2007 may be subject to a 0.75% contingent deferred sales charge if
     they are redeemed within an 18-month "holding period" measured from the
     beginning of the calendar month of their purchase. That sales charge will be
     calculated on the lesser of the original net asset value of the redeemed shares
     or the aggregate net asset value of the redeemed shares at the time of
     redemption.

     The Class A contingent deferred sales charge does not apply to shares purchased
     by the reinvestment of dividends or capital gain distributions and will not
     exceed the amount of the concessions the Distributor paid on your purchases of
     a Fund's Class A shares.

     The Distributor pays a concession from its own resources on certain purchases
     of Class A shares of one or more of the Oppenheimer funds that, in the
     aggregate, total $1 million or more. Beginning October 22, 2007, if purchases
     of a Fund's Class A shares are included in any such purchase, the Distributor
     will pay the concession on those Fund shares at the rate of 0.75% of their net
     asset value. A concession will not be paid on shares purchased by exchange or
     shares that were previously subject to a front-end sales charge and dealer
     concession.

     Letters of Intent submitted prior to October 22, 2007 will be subject to the
     contingent deferred sales charge that was in effect at the time the Letter of
     Intent was submitted and the Distributor will pay the concession that was
     applicable to those shares at that time. Unless otherwise agreed to by the
     Distributor, the terms of any Letter of Intent submitted prior to October 22,
     2007 will continue until its completion.
