The data contained in this presentation that are not historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Exchange Act. Such statements may relate to capital expenditures, drilling and exploitation activities, production efforts and sales volumes, proved, probable, and possible reserves, operating and administrative costs, future operating or financial results, cash flow and anticipated liquidity, business strategy, property acquisitions, and the availability of drilling rigs and other oil field equipment and services. These forward-looking statements are generally accompanied by words such as estimated, projected, potential, anticipated, forecasted or other words that convey the uncertainty of future events or outcomes. Although we believe the expectations and forecasts reflected in these and other forward-looking statements are reasonable, we can give no assurance they will prove to have been correct. These statements are based on our current plans and assumptions and are subject to a number of risks and uncertainties such as potential litigation as further outlined in our most recent 10-K and 10-Q. Therefore, the actual results may differ materially from the expectations, estimates or assumptions expressed in or implied by any forward-looking statement made by or on behalf of the Company. Cautionary Note to U.S. Investors The SEC has recently modified its rules regarding oil and gas reserve information that may be included in filings with the SEC. The newly applicable rules allow oil and gas companies to disclose not only proved reserves, but also probable and possible reserves that meet the SEC s definitions of such terms. We disclose proved, probable and possible reserves in our filings with the SEC. Our reserves as of June 30, 2012 were estimated by DeGolyer & MacNaughton, W.D Von Gonten & Co. ( Von Gonten ), and Pinnacle Energy Services, LLC ( Pinnacle ), independent petroleum engineering firms. In this presentation, we make reference to probable reserves and 2P reserves that aggregate proved and probable reserves. These estimates are by their nature more speculative than estimates of proved reserves and are subject to greater uncertainties, and accordingly the likelihood of recovering those reserves is subject to substantially greater risk. Please see Appendix. 2

Innovation for Increasing Recovery
Industry at risk of losing vast quantities of reserves and production as mature horizontal wells encounter liquid loading Our technology re-establishes economic production of the Tail reserves at risk due to the liquid loading, as it: Supplements & enhances existing rod pump Mobilizes remaining fluid to rod pump inlet Four commercial installations completed demonstrating success Risk-sharing participation model 20
BEFORE: Conventional Rod Pump Either fluid level eventually drops to a level where rod pump or gas lift are no longer effective, or Fluid production in gas well builds and eventually shuts off gas production This can leave substantial volumes of oil and gas unrecovered (the Tail ) AFTER: GARP Adds substantial new reserves at low cost Benefit = up to 25% incremental recovery Benefit = extends life of lease(s) Low development cost per net BOE Patented 21
