                 BP AMOCO AND ARCO GET FTC GO-AHEAD TO COMBINE
                 ---------------------------------------------

BP Amoco and Atlantic Richfield Company (ARCO) today announced that they have
received clearance from the US Federal Trade Commission (FTC) for the
combination of their companies.

The union, which was originally agreed a year ago, will create a combined group
with a market capitalisation of some $200 billion.

BP Amoco chief executive Sir John Browne said: "We are very pleased to have
received FTC approval. We will now close the deal and rapidly implement the
plans we have in place to integrate our operations worldwide. We intend to move
quickly to deliver the significant value of this union to the shareholders of
the new group."

BP Amoco and ARCO said they plan to close the transaction at 0800 hours, London
time, on Tuesday, April 18, 2000. The last day of trading in ARCO common stock
will therefore be Monday, April 17, 2000.
