                        BP TO SELL CORYTON REFINERY TO
                     PETROPLUS HOLDINGS AG FOR $1.4 BILLION



BP announced today that it has agreed to sell, subject to required regulatory
approvals, its Coryton Refinery in Essex, UK, to Petroplus Holdings AG, a
leading independent refiner and wholesaler of petroleum products headquartered
in Zug, Switzerland.


The sale price of $1.4 billion - plus hydrocarbons to be valued at closing -
includes the adjacent bulk terminal and BP's UK bitumen business which is
closely integrated with the refinery. BP and Petroplus have also entered into a
long term supply agreement which will provide BP's UK based retail and other
businesses with the products they require.


"BP is very much committed to the UK and does not need to own a refinery in the
UK to offer its UK customers the best in fuel products," said John Manzoni,
chief executive of BP's refining and marketing business.


"The sale will enable us to concentrate on continually improving our remaining
European refineries so that they remain top class assets."


Following completion of the sale, which is expected mid 2007, the staff at the
refinery will transfer to Petroplus but BP will continue to operate its own UK
logistics and supply infrastructure.


Notes to Editors:


- -  Coryton started up in 1953 and currently employs around 540 BP staff
   and a similar number of contractors.

- -  The refinery has a crude distillation capacity of 172,000 barrels a day
   and can also process up to 70,000 barrels a day of other feedstocks.

- -  Coryton produces petrol and diesel, including the new 'cleaner' fuels,
   aviation fuels, liquefied petroleum gas (LPG), fuel oils and bitumen.

- -  Excluding Coryton, BP owns or has shareholdings in seven European
   refineries, with its principal refining assets being in Germany, Spain and
   the Netherlands.

- -  Petroplus Holdings AG currently owns and operates three European
   refineries - Teeside Refinery in Teeside, UK, Cressier Refinery in Neuchatel,
   Switzerland, and the Belgium Refining Company's refinery in Antwerp,
   Belgium - with a total crude capacity of 295,000 barrels a day.



- -  Petroplus is also in the process of purchasing a refinery in
   Ingolstadt, Germany, with a crude capacity of 110,000 barrels a day from
   ExxonMobil Central Europe Holding GmbH.
