TNK stake share payment dates

BP PLC
11 June 2004



                        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.
