CALGARY, ALBERTA–(EMWNews – Aug. 11, 2008) – BP p.l.c. (TSX:BP.U) (NYSE:BP) today announced the voluntary de-listing of its American Depositary Shares, each representing six ordinary shares, from the Toronto Stock Exchange. BP’s American Depositary Shares will continue to be listed on the New York Stock Exchange in the United States and its Ordinary Shares will continue to be listed on the London Stock Exchange.

BP has decided to withdraw its listing from the Toronto Stock Exchange to streamline operations and eliminate the additional administrative requirements of maintaining multiple share listings. The withdrawal is expected to be effective at the close of trading on 15 August 2008.

BP does not believe that withdrawing its listing from the Toronto Stock Exchange will have any impact on the liquidity of its American Depositary Shares. BP shares traded on the Toronto Stock Exchange typically account for less than one percent of the average daily trading volume of BP shares traded on the NYSE.
