BP FULFILS EC UNDERTAKING WITH GAS SALE TO TULLOW OIL

BP announced today that it has completed the sale of certain UK Southern North
Sea gas assets to Tullow Oil Plc. The sale fulfils undertakings BP made to the
European Commission at the time of the Atlantic Richfield (ARCO) acquisition,
completed in April 2000.

The sale is of ARCO's share in the Thames, Hewett and Welland producing fields
and their associated pipelines and terminal interests. It follows the
completion in February of the sale of ARCO's share of the Murdoch and Boulton
gas fields and ARCO's interest in the Caister-Murdoch system to Tullow. BP
first announced these sale agreements in July 2000.

Steve Marshall, BP's Regional President in charge of UK upstream said: 'We are
delighted to have completed this sale to Tullow in fulfilment of the
commitment given to the European Commission at the time of the ARCO purchase.
We will assist Tullow and its partners to ensure a safe and efficient transfer
of these important North Sea fields.'

Notes to Editors:


In addition to these assets, BP is also in the process of selling to Tullow
the Orwell and Gawain fields, which are satellites to Thames, and some
additional exploration licences. Completion of the sale of Gawain is
anticipated in the next few weeks and completion of the sale of Orwell is
anticipated in the next few months. In total Tullow is set to pay BP some £201
million ($287 million) for the package of assets with an effective date of
January 1, 2000.


In the short term ARCO will continue to operate Thames, Welland, Gawain and
Orwell on behalf of the co-venturers. It is anticipated that ExxonMobil will
assume operatorship of Thames, Welland and Gawain. Operatorship of Orwell is
yet to be decided. A further announcement will be made when these matters are
finalised.

ARCO and BP were advised on the sale by Schroder Salomon Smith Barney of
London. Net gas production from the total package of fields being transferred
to Tullow amounts to about 150 million cubic feet a day (cf/d). BP produces
about 1.6 billion cf/d of gas in the UK and about 8 billion cf/d worldwide.
BP's UK gas reserves are about 5.5 trillion cubic feet (tcf) and worldwide
around 43 tcf.

Tullow Oil Plc is a UK-registered independent oil and gas company that has
interests worldwide. In the UK Tullow's major existing assets are operatorship
(and 60 per cent) of the Ryedale gas-to-power project, which includes three
producing gas fields in North Yorkshire and the Knapton Electricity Generating
Station. Tullow has also taken over the operatorship of the facilities for the
nearby Hatfield Moor gas storage system. Tullow also has international
interests in Algeria, Bangladesh, Egypt, India, Ivory Coast, Pakistan and
Romania.
