                     BP Second Quarter 2006 Trading Update

This trading update is aimed at providing estimates regarding revenue and
trading conditions experienced by BP in the second quarter ended June 30, 2006,
and estimates of identified non-operating items expected to be included in that
quarter's result. The second quarter margin, price, realisation, cost,
production and other data referred to below are currently provisional, some
being drawn from figures applicable to the first month or so of the quarter. All
such data are subject to change and may differ quite considerably from the final
numbers that will be reported on July 25, 2006. In particular, data is not
available at this time that would allow an estimate of potential IFRS fair value
accounting gains or charges, or of any potential consolidation adjustment. This
trading update is produced in order to provide greater disclosure to investors
and potential investors of currently expected outcomes, and to ensure that they
all receive equal access to the same information at the same time.

Overall BP production in 2Q'06 is expected to be around 4,010 mboed (thousand
barrels of oil equivalent per day). Excluding volumes from TNK-BP operations,
production in 2Q'06 is expected to be around 3,010 mboed, versus 3,041 mboed in
1Q'06. This reduction primarily reflects the impact of divestments. BP's net
share of production from TNK-BP is expected to be approximately 1,000 mboed,
versus 994 mboed in 1Q'06.

* The Refining Global Indicator Margin (GIM) is a generic indicator. Actual
margins realised by BP may vary significantly due to a variety of factors,
including specific refinery configurations, crude slate and operating practices.

The second quarter's Global Indicator Margin (GIM) was higher than the GIM for
both 1Q'06 and 2Q'05. The increase in BP's actual refining margins quarter on
quarter is expected to be slightly lower than that suggested by the increase in
the GIM. Overall marketing margins are expected to be similar to those in 1Q'06.
The phased re-commissioning of the Texas City refinery commenced at the end of
March.

Gas, Power and Renewables

GP&R margins for the quarter are expected to be higher than 1Q'06 largely due to
improved North American margins.

Other Businesses and Corporate

The charge in Other Businesses and Corporate is expected to be in line with
guidance given in our February 2006 Strategy Presentation for an annual charge
of $900m +/- $200m.

Identified Non-Operating Items (NOIs)

Aggregate non-operating items in 2Q'06 are not expected to be material, with
gains (primarily from asset sales) offsetting other items (including an
incremental charge of around $500m with respect to the 2005 Texas City refinery
incident).

Interest Expense

The total consolidated interest charge is expected to be around $100m.

Tax Rate

The effective tax rate for the quarter is expected to be around 36 per cent,
slightly higher than in 1Q'06, due largely to rising oil prices. This does not
include the impact of the yet-to-be enacted increase in the UK North Sea tax
rate, which is currently expected to be recognised in 3Q'06. The anticipated
2006 full year effective tax rate remains at around 39 per cent, as indicated in
our February 2006 Strategy Presentation.

Gearing

Gearing for the quarter is expected to be similar to the 1Q'06 level of 16 per
cent.

Distributions to Shareholders

During the quarter the company bought back 376 million shares for a total
consideration of $4.5bn. Shares outstanding at June 27th 2006, excluding
treasury shares, were 19,993 million. As in previous quarters, BP has entered
into an arrangement that allows the share buy back programme to be continued
during the closed period which commenced at close of business in London on June
30th. The 2Q'06 dividend of 9.375 cents per share announced at the time of our
1Q'06 results was paid in June. The dividend to be paid in 3Q'06 will be
announced on July 25th in conjunction with our 2Q'06 Stock Exchange
Announcement.

Rules of Thumb

Important note: The rules of thumb shown below were provided with BP's strategy
update on February 7th, 2006 and were intended to give directional indicators of
the impact of changes in the trading environment relative to that of 2005 on
BP's 2006 full yearpre-tax results. These rules of thumb are approximate.
Especially over short periods, changes in prices, margins, differentials,
seasonal demand patterns, and other factors can be material. Particular
differences may arise due to higher government shares of Exploration and
Production revenues in some jurisdictions at current price levels, as well as
from variations between the refining Global Indicator Margin (GIM) and BP's
realised refining margins due to crude price levels and differentials, product
price movements and other factors. The GIM rule of thumb reflects the
sensitivity to the overall group to changes in refining margins. Many other
factors will affect BP's earnings quarter by quarter. Actual results in
individual quarters may therefore differ significantly from the estimates
implied by the application of these rules of thumb.

2006 Operating Environment Rules of Thumb: impact on replacement cost pre-tax
operating profit per year of changes relative to 2005 environment
                                                           Full Year
Oil Price - Brent +/- $1/bbl                               $500m
Gas - Henry Hub +/- $ 0.10/mcf                              $80m
Refining - GIM +/- $ 1/bbl                                 $950m

refining and marketing margins; margins in the GP&R business; the charge in
Other Businesses & Corporate; the amount of non-operating items; the total
consolidated interest charge; the effective tax rate; and gearing. By their
nature, forward-looking statements involve risks and uncertainties because they

Actual results may differ from those expressed in such statements
depending on a variety of factors, including the timing of bringing new fields
