We have used the words "anticipate", "believe", "could", "estimate", "expect", "intend", "may", "plan", "predict", "project", "should", "will" and similar terms and phrases to identify forward-looking statements in this Presentation. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. Our operations involve risks and uncertainties, many of which are outside our control, and any one of which, or a combination of which, could materially affect our results of operations and whether the forward-looking statements ultimately prove to be correct. Actual results and trends in the future may differ materially from those suggested or implied by the forward-looking statements depending on a variety of factors which are described in greater detail in our filings with the SEC. All future written and oral forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the previous statements.

Acquisition and Capital Review

Acquisition and Capital Overview Closed in May, 2007 Used $1.1 billion of cash Paid off all short-term debt Pro Forma Debt:Cap of 33%* Assessing capital program $1 billion over next five years Assessing scope and timing Capturing synergies Continue making progress and learning ACQUISITION $900 million budgeted in 2007 Largest program in company history $100 million of additional, incremental EBITDA in 2007 Re-organization of capital team CAPITAL *At the end of June, the Company's debt to capitalization was 37%. By August 3rd the Company repaid $250 million of outstanding borrowings on our revolving line of credit. Including the debt repayments subsequent to the quarter, our pro-forma debt to capitalization ratio would have been 33% at June 30, 2007.
