These unaudited pro forma condensed consolidated financial statements are not necessarily indicative of the financial position or results of operations that would have occurred had the Acquisition been effected on the assumed dates.  Additionally, future results may vary significantly from the results reflected in the unaudited pro forma condensed consolidated statement of operations due to normal production declines, changes in prices, future transactions, and other factors.
