Statements in this presentation that contain words such as "will," "expect" or "estimate,"
or otherwise relate to the future, are forward-looking and involve risks and uncertainties
that could significantly affect expected results.  Factors that could cause results to differ
materially include, but are not limited to: exploration risks such as drilling of unsuccessful
wells, global commodity pricing fluctuations and supply/demand considerations for oil,
gas and chemicals; higher than expected costs; political risks; changes in tax rates;
unrealized acquisition benefits or higher than expected integration costs; and not
successfully completing (or any material delay in) any expansion, capital expenditure,
acquisition or disposition.  You should not place undue reliance on these forward-looking
statements which speak only as of the date of this presentation.  Unless legally required,
