Forward-Looking Statements

All statements in this release other than historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements and all references to financial estimates rely on a number of assumptions concerning future events and are subject to a number of uncertainties, including (i) the effects of the continued volatility of commodity prices and the related macroeconomic and political environment, (ii) risks and uncertainties related to the capital markets generally, (iii) whether the Issuers will consummate the offering of the New Notes and (iv) other factors, many of which are outside its control, which could cause actual results to differ materially from such statements.
