BP Completes Vastar Purchase

Houston (Sept. 15) - BP today announced completion of the purchase of Vastar
Resources, Inc. (VRI), following a favourable vote by VRI's minority
shareholders to accept BP's offer of $83 per share. BP already owned 81.8 per
cent of VRI shares, acquired when the company purchased ARCO earlier this
year. The cost of this purchase is approximately $1.5 billion.

'The Vastar acquisition is a great strategic fit with our US upstream
portfolio,' said David H Welch, BP's Houston-based Vice President, Upstream.
'In the Mid Continent, the Rocky Mountains, the Gulf Coast, and the
Continental Shelf and Deepwater areas of the Gulf of Mexico, this acquisition
strengthens our oil and gas portfolio,' Welch said.
