                       BOC to buy out Duke Energy's stake

                in joint venture to pressurize Mexican oil field



Windlesham, UK, 25 May 2004 -- The BOC Group and Duke Energy have agreed to
terms on the sale of Duke Energy's 30 percent ownership interest in Compania de
Nitrogeno de Cantarell, S.A. de C.V. (CNC) - the joint venture company that owns
the world's largest nitrogen complex and supplies nitrogen to maintain pressure
and increase oil recovery in Mexico's Cantarell oil field.

BOC has agreed to purchase Duke Energy's stake in CNC for US$59.7 million in
cash, increasing BOC's overall stake in CNC to 65 per cent. The deal is subject
to lender approval and certain other conditions. Duke Energy acquired its
ownership interests in CNC when it acquired Westcoast Energy of Canada in 2002.
Marubeni Corporation and Marubeni America Corporation will retain 25 percent and
10 percent, respectively.

CNC supplies nitrogen via pipeline to Pemex Exploracion y Produccion, the
exploration and production arm of Petroleos Mexicanos (Pemex), Mexico's national
oil company. Since 2000, when Pemex began injecting nitrogen into the Cantarell
field to reduce the reservoir's natural decline of pressure, oil production has
doubled to 2 million barrels per day (BPD). Pemex attributes an increase of some
600 thousand BPD in oil production to the nitrogen injection.

"BOC is pleased to increase its share in CNC and to reaffirm its commitment to
the success of the Cantarell project," said Ned Galbally, senior vice president,
Process Gas Solutions, BOC. "This is a very important undertaking for BOC. We
led the consortium that was awarded this project in the 1990s and we continue to
stay closely involved in the day-to-day operation. Today, the Cantarell oilfield
nitrogen pressurization project is a huge success and BOC has assumed an even
larger role in this project's future."
