GLOSSARY AND SELECTED ABBREVIATIONS The following are abbreviations and definitions of certain terms that may be used in this report. Unless listed below, all defined terms under Rule 4-10(a) of Regulation S-X shall have their statutorily prescribed meanings. ‘‘2D seismic data’’ . . . . . . . . . . . . . . . Two-dimensional seismic data, serving as interpretive data that allows a view of a vertical cross-section beneath a prospective area. ‘‘3D seismic data’’ . . . . . . . . . . . . . . . Three-dimensional seismic data, serving as geophysical data that depicts the subsurface strata in three dimensions. 3D seismic data typically provides a more detailed and accurate interpretation of the subsurface strata than 2D seismic data. ‘‘API’’ . . . . . . . . . . . . . . . . . . . . . . . A specific gravity scale, expressed in degrees, that denotes the relative density of various petroleum liquids. The scale increases inversely with density. Thus lighter petroleum liquids will have a higher API than heavier ones. ‘‘ASC’’ . . . . . . . . . . . . . . . . . . . . . . . Financial Accounting Standards Board Accounting Standards Codification. ‘‘ASU’’ . . . . . . . . . . . . . . . . . . . . . . .

A standard measure of volume for petroleum corresponding to approximately 42 gallons at 60 degrees Fahrenheit. ‘‘BBbl’’ . . . . . . . . . . . . . . . . . . . . . . . Billion barrels of oil. ‘‘BBoe’’ . . . . . . . . . . . . . . . . . . . . . . Billion barrels of oil equivalent. ‘‘Bcf’’ . . . . . . . . . . . . . . . . . . . . . . . . Billion cubic feet. ‘‘Boe’’ . . . . . . . . . . . . . . . . . . . . . . . Barrels of oil equivalent. Volumes of natural gas converted to barrels of oil using a conversion factor of 6,000 cubic feet of natural gas to one barrel of oil. ‘‘Boepd’’ . . . . . . . . . . . . . . . . . . . . . . Barrels of oil equivalent per day. ‘‘Bopd’’ . . . . . . . . . . . . . . . . . . . . . . Barrels of oil per day. ‘‘Bwpd’’ . . . . . . . . . . . . . . . . . . . . . . Barrels of water per day. ‘‘Debt cover ratio’’ . . . . . . . . . . . . . . . The ‘‘debt cover ratio’’ is broadly defined, for each applicable calculation date, as the ratio of (x) total long-term debt less cash and cash equivalents and restricted cash, to (y) the aggregate EBITDAX (see below) of the Company for the previous twelve months. ‘‘Developed acreage’’ . . . . . . . . . . . . . The number of acres that are allocated or assignable to productive wells or wells capable of production. ‘‘Development’’ . . . . . . . . . . . . . . . . . The phase in which an oil or natural gas field is brought into production by drilling development wells and installing appropriate production systems. 3
