The SEC permits oil and gas companies, in their filings with the SEC, to disclose only “reserves” as defined by SEC rules. Estimates of reserves in this communication are based on economic

assumptions with regard to commodity prices (NYMEX oil and natural gas futures prices as of May 3, 2012) that differ from the prices required by the SEC (historical 12 month average) to be used in calculating reserves estimates prepared in accordance with SEC rules. In addition, the estimates of reserves in this press release were prepared by internal reserve engineers and are based on various assumptions, including assumptions related to oil and natural gas prices as discussed above, drilling and operating expenses, capital expenditures, taxes and availability of funds. Our internal estimates of proved reserves may differ materially from the estimates of our proved reserves as of December 31, 2012 that will be prepared by Netherland, Sewell & Associates, Inc. as a result of the SEC pricing and other assumptions employed by an independent reserve engineering firm.
