Forward Looking Statements Except for historical information, statements made in this presentation, including those relating to significant potential opportunities, future earnings, resource potential, cash flow, capital expenditures, production growth, planned number of wells (as well as the timing of rig operations, natural gas processing plant commissioning and operations, fracture stimulation activities and the completion of wells and the expected dates that wells are producing hydrocarbons that are sold) and potential ethane sales pipeline projects are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are indicated by words such as expected, expects, assumes, anticipates and similar words. These statements are based on assumptions and estimates that management believes are reasonable based on currently available information; however, management's assumptions and the company's future performance are subject to a wide range of business risks and uncertainties, and there is no assurance that these goals and projections can or will be met. Any number of factors could cause actual results to differ materially from those in the forward-looking statements, including (without limitation) the following: adverse economic conditions in the United States and globally; the difficult and adverse conditions in the domestic and global capital and credit markets; domestic and global demand for oil and natural gas; sustained or further declines in the prices the company receives for oil and natural gas; the effects of government regulation, permitting and other legal requirements; the geologic quality of the company s properties with regard to, among other things, the existence of hydrocarbons in economic quantities; uncertainties about the estimates of the company s oil and natural gas reserves; the company s ability to increase production and oil and natural gas income through exploration and development; the company s ability to successfully apply horizontal drilling techniques and tertiary recovery methods; the number of well locations to be drilled, the cost to drill and the time frame within which they will be drilled; the effects of adverse weather on operations; drilling and operating risks; the ability of contractors to timely and adequately perform their drilling, construction, well stimulation, completion and production services; the availability of equipment, such as drilling rigs and transportation pipelines; changes in the company s drilling plans and related budgets; the adequacy of capital resources and liquidity including (without limitation) access to additional borrowing capacity; uncertainties relating to the potential divestiture of the Niobrara assets, including the ability to reach an agreement with a potential purchaser on terms acceptable to the company; and uncertainties associated with our legal proceedings and the outcome. The company undertakes no obligation to publicly update or revise any forward-looking statements. Further information on the company s risks and uncertainties is available in the company's filings with the Securities and Exchange Commission. The company's internal estimates of reserves may be subject to revision and may be different from estimates by the company's external reservoir engineers at year end. Although the company believes the expectations and forecasts reflected in these and other forward-looking statements are reasonable, it can give no assurance they will prove to have been correct. They can be affected by inaccurate assumptions or by known or unknown risks and uncertainties. 2
Estimates Used in This Presentation Hydrocarbon Volumes The SEC permits publicly-reporting oil and gas companies to disclose proved reserves in their filings with the SEC. Proved reserves are estimates that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. SEC rules also permit the disclosure of probable and possible reserves. Rex Energy discloses proved reserves but does not disclose probable or possible reserves. We may use certain broader terms such as resource potential, EUR (estimated ultimate recovery of resources, defined below) and other descriptions of volumes of potentially recoverable hydrocarbon resources throughout this presentation. These broader classifications do not constitute reserves as defined by the SEC and we do not attempt to distinguish these classifications from probable or possible reserves as defined by SEC guidelines. The company defines EUR as the cumulative oil and gas production expected to be economically recovered from a reservoir or individual well from initial production until the end of its useful life. Our estimates of EURs and resource potential have been prepared internally by our engineers and management without review by independent engineers. These estimates are by their nature more speculative than estimates of proved, probable and possible reserves and accordingly are subject to substantially greater risk of being actually realized. We include these estimates to demonstrate what we believe to be the potential for future drilling and production by the company. Ultimate recoveries will be dependent upon numerous factors including actual encountered geological conditions, the impact of future oil and gas pricing, exploration and development costs, and our future drilling decisions and budgets based upon our future evaluation of risk, returns and the availability of capital and, in many areas, the outcome of negotiation of drilling arrangements with holders of adjacent or fractional interest leases. Estimates of resource potential and other figures may change significantly as development of our resource plays provide additional data and therefore actual quantities that may ultimately be recovered will likely differ from these estimates. Potential Drilling Locations Our estimates of potential drilling locations are prepared internally by our engineers and management and are based upon a number of assumptions inherent in the estimate process. Management, with the assistance of engineers and other professionals, as necessary, conducts a topographical analysis of our unproved prospective acreage to identify potential well pad locations using operationally approved designs and considering several factors, which may include but are not limited to access roads, terrain, well azimuths, and well pad sizes. For our operations in Pennsylvania, we then calculate the number of horizontal well bores for which the company appears to control sufficient acreage to drill the lateral wells from each potential well pad location to arrive at an estimated number of net potential drilling locations. For our operations in Ohio, we calculate the number of horizontal well bores that may be drilled from the potential well pad and multiply this by the company s net working interest percentage of the proposed unit to arrive at an estimated number of net potential drilling locations. In both cases, we then divide the unproved prospective acreage by the number of net potential drilling locations to arrive at an average well spacing. Management uses these estimates to, among other things, evaluate our acreage holdings and to formulate plans for drilling. Any number of factors could cause the number of wells we actually drill to vary significantly from these estimates, including: the availability of capital, drilling and production costs, commodity prices, availability of drilling services and equipment, lease expirations, regulatory approvals and other factors. Potential ASP Units Our estimates of potential target areas, which we sometimes refer to as units, for which we may use an Alkali-Surfactant-Polymer ( ASP ) flood as a method of tertiary recovery have been prepared internally by our engineers and management. These estimates are based on our evaluation of the sand bodies underlying certain of our properties in the Illinois Basin. We have identified certain characteristics which we believe are desirable for potential ASP projects, including sand bodies with no less than 60 acres of areal extent and net reservoir thickness no less than 15 feet. We have subdivided the sand bodies to determine potential ASP target areas, which have been modeled such that no individual target area or unit would exceed 500 acres. We include these estimates to demonstrate what we believe to be the future potential for ASP tertiary recovery for the company. These estimates are highly speculative in nature and ultimate recoveries will depend on a number of factors, including the ASP technology utilized, the characteristics of the sand bodies and the reservoirs, geological conditions encountered, our decisions regarding capital, and the impact of future oil prices. 3
