2 Forward-looking and Cautionary Statements Forward-looking Statement: All statements, other than statements of historical fact, appearing in this presentation constitute forward-looking statements within the meaning of the Private Securities Litigation Reform Act of These forward looking statements include, among other things, statements about our expectations, beliefs, intentions or business strategies for the future, statements concerning our outlook with regard to the timing and amount of future production of oil, natural gas liquids and natural gas, price realizations, the nature and timing of capital expenditures for exploration and development, plans for funding operations and drilling program capital expenditures, the timing and success of specific projects, operating costs and other expenses, proved oil and natural gas reserves, liquidity and capital resources, outcomes and effects of litigation, claims and disputes and derivative activities. Forward looking statements may include words such as anticipate, believe, could, estimate, expect, forecast, foresee, intend, may, plan, potential, predict, project, seek, will, or other words or expressions concerning matters that are not historical facts. These statements involve certain risks and uncertainties that may cause actual results to differ materially from expectations as of the date of this presentation. Except as otherwise disclosed, the forward looking statements do not reflect the impact of possible or pending acquisitions, investments, divestitures or restructurings. The absence of errors in input data, calculations and formulas used in estimates, assumptions and forecasts cannot be guaranteed. We base our forward looking statements on information currently available to us, and we undertake no obligation to correct or update these statements whether as a result of new information, future events or otherwise. Additional information regarding our forward looking statements and related risks and uncertainties that could affect future results of Energen, can be found in the Company s periodic reports filed with the Securities and Exchange Commission and available on the Company s website ( Cautionary Statements: The SEC permits oil and gas companies to disclose in SEC filings only proved, probable and possible reserves that meet the SEC s definitions for such terms, and price and cost sensitivities for such reserves, and prohibits disclosure of resources that do not constitute such reserves. Outside of SEC filings, we use the terms estimated ultimate recovery or EUR, reserve or resource potential, contingent resources and other descriptions of volumes of non-proved reserves or resources potentially recoverable through additional drilling or recovery techniques. These estimates are inherently more speculative than estimates of proved reserves and are subject to substantially greater risk of actually being realized. We have not risked EUR estimates, potential drilling locations, and resource potential estimates. Actual locations drilled and quantities that may be ultimately recovered may differ substantially from estimates. We make no commitment to drill all of the drilling locations that have been attributed these quantities. Factors affecting ultimate recovery include the scope of our ongoing drilling program, which will be directly affected by the availability of capital, drilling, and production costs, availability of drilling and completion services and equipment, drilling results, lease expirations, regulatory approvals, and geological and mechanical factors. Estimates of unproved reserves, type/decline curves, per-well EUR, and resource potential may change significantly as development of our oil and gas assets provides additional data. Additionally, initial production rates contained in this presentation are subject to decline over time and should not be regarded as reflective of sustained production levels. 2

34 Non-GAAP Financial Measures Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Natural Gas Reserves (GAAP) / PV-10 (non-gaap): The standardized measure of discounted future net cash flows (SMOG) is the Company s GAAP estimate of the present value of future net revenues from proved oil and gas reserves after deducting estimated production and ad valorem taxes, operating expenses, development costs, and income taxes discounted at an annual rate of 10%. PV-10 is a non-gaap measure that excludes the Company s estimates of future income taxes (discounted at an annual rate 10%). The Company believes that PV-10 allows for additional comparability among companies in the oil and gas industry due to the unique factors that may impact the timing of future income taxes to be paid. The Company also believes PV-10 to be important for evaluating the relative significance of its oil and gas properties and that the presentation of the non-gaap financial measure of PV-10 provides useful information to investors because it is widely used by professional analysts and investors in evaluating oil and gas companies. The Company believes disclosing the year-over-year change in the PV-10 for Proved Developed Producing (PDP) reserves is a meaningful indication of the increase in value of the Company s producing properties. The following table reconciles the Company s standardized measure of discounted future net cash flows (the most directly comparable measure calculated and presented in accordance with GAAP) to PV-10. PV-10 should not be considered as an alternative to the standardized measure as computed under GAAP.
