BP AND AAR AGREE CHANGE TO SHARE

PAYMENT DATES FOR TNK STAKE

BP and Alfa, Access and Renova (AAR) completed their sale and
purchase agreement relating to TNK-BP on 29 August 2003. BP and AAR
today agreed to change the dates on which BP is due, under the terms
of that agreement, to issue AAR with three tranches of BP p.l.c.
shares, each tranche with a value of US$1.25 billion.

The issue dates have been changed from 29 August 2004, 29 August 2005
and 29 August 2006 to 20 September 2004, 20 September 2005 and 20
September 2006, respectively.

The issue dates have been moved in order to avoid BP's third quarter
ex-dividend date falling within the calculation period for
determining the number of BP p.l.c. shares to be issued to AAR in
each tranche, thereby reducing the potential for volatility during
that period. There is no incremental cost to BP or its shareholders
as a result of this change in issue dates.
