Total assets at December 31, 2011 were $184,812,000 compared to $208,160,000 at December 31, 2010. Proved reserves at December 31, 2011 were 8,853,000 barrels of oil and 53,396,000 thousand cubic feet (“Mcf”) of natural gas with 77% of these reserves developed compared to 7,885,000 barrels of oil and 53,346,000 Mcf of natural gas and 73% of these reserves developed at December 31, 2010.

Oil and gas sales were $88,429,000 in 2011 as compared to $81,685,000 in 2010. The average prices received (excluding realized gains and losses from derivatives) in 2011 were $6.38 per Mcf of gas and $90.04 per barrel of oil, as compared to $5.75 per Mcf of gas and $75.82 per barrel of oil in 2010. In 2011, the Company produced 5,000,000 Mcf of gas and 628,000 barrels of oil, as compared to 5,939,000 Mcf of gas and 627,000 barrels of oil in 2010. The increase in net income was principally due to higher prices received for sales of our oil and gas production, realized gains on derivative instruments and a decrease in interest expense partially offset by increased lease operating expenses, depreciation and depletion and income tax expenses.

Words such as "expects," "anticipates," "intends," "plans," "believes", "projects" and "estimates," and variations of such words and similar expressions are intended to identify such forward-looking statements. These statements constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, and are subject to the safe harbors created thereby. These statements are not guarantees of future performance and involve risks and uncertainties and are based on a number of assumptions that could ultimately prove inaccurate and, therefore, there can be no assurance that they will prove to be accurate. Actual results and outcomes may vary materially from what is expressed or forecast in such statements due to various risks and uncertainties.
