This presentation includes forward-looking statements, which give the Company's current expectations or forecasts of
future events based on currently available information. Forward-looking statements are statements that are not
historical facts, such as expectations regarding drilling plans, including the acceleration thereof, production rates and
guidance, resource potential, incremental transportation capacity, exit rate guidance, net present value, development
plans, progress on infrastructure projects, exposures to weak natural gas prices, changes in the Company's liquidity,
changes in acreage positions, expected expenses, expected capital expenditures, and projected debt balances. The
assumptions of management and the future performance of the Company are subject to a wide range of business risks
and uncertainties and there is no assurance that these statements and projections will be met. Factors that could affect
the Company's business include, but are not limited to: the risks associated with drilling of oil and natural gas wells; the
Company's ability to find, acquire, market, develop, and produce new reserves; the risk of drilling dry holes; oil and
natural gas price volatility; derivative transactions (including the costs associated therewith and the abilities of
counterparties to perform thereunder); uncertainties in the estimation of proved, probable, and possible reserves and
in the projection of future rates of production and reserve growth; inaccuracies in the Company's assumptions
regarding items of income and expense and the level of capital expenditures; uncertainties in the timing of exploitation
expenditures; operating hazards attendant to the oil and natural gas business; drilling and completion losses that are
generally not recoverable from third parties or insurance; potential mechanical failure or underperformance of
significant wells; availability and limitations of capacity in midstream marketing facilities, including processing plant and
pipeline construction difficulties and operational upsets; climatic conditions; availability and cost of material, supplies,
equipment and services; the risks associated with operating in a limited number of geographic areas; actions or
inactions of third-party operators of the Company's properties; the Company's ability to retain skilled personnel;
diversion of management's attention from existing operations while pursuing acquisitions or dispositions; availability of
capital; the strength and financial resources of the Company's competitors; regulatory developments; environmental
risks; uncertainties in the capital markets; general economic and business conditions (including the effects of the
worldwide economic recession); industry trends; and other factors detailed in the Company's most recent Form 10-K,
Form 10Q and other filings with the Securities and Exchange Commission. If one or more of these risks or
uncertainties materialize (or the consequences of such a development changes), or should underlying assumptions
prove incorrect, actual outcomes may vary materially from those forecasted or expected. The Company undertakes no
obligation to publicly update or revise any forward-looking statements except as required by law.

Forward-Looking Statements and Terminology Used

For filings reporting year-end 2010 reserves, the SEC permits the optional disclosure of probable and possible
reserves.  The Company has elected not to report probable and possible reserves in its filings with the SEC.  We use
the term “net risked resources” to describe the Company’s internal estimates of volumes of natural gas and oil that are
not classified as proved reserves but are potentially recoverable through exploratory drilling or additional drilling or
recovery techniques.  Estimates of unproved resources are by their nature more speculative than estimates of proved
reserves and accordingly are subject to substantially greater risk of actually being realized by the Company.  Estimates
of unproved resources may change significantly as development provides additional data, and actual quantities that are
ultimately recovered may differ substantially from prior estimates. We use the term “BFIT NPV10” to describe the
Company’s estimate of before income tax net present value discounted at 10 percent resulting from project economic
evaluation. The net present value of a project is calculated by summing future cash flows generated by a project, both
inflows and outflows, and discounting those cash flows to arrive at a present value.  Inflows primarily include revenues
generated from estimated production and commodity prices at the time of the analysis.  Outflows include drilling and
completion capital and operating expenses.  Net present value is used to analyze the profitability of a project. 
Estimates of net present value may change significantly as additional data becomes available, and with adjustments in
prior estimates of actual quantities of production and recoverable reserves, commodity prices, capital expenditures,
and/or operating expenses.
