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 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, 2011 were estimated by DeGolyer & MacNaughton, W.D Von Gonten & Co. ( Von Gonten ), and Lee Keeling and Associates, Inc. ( Keeling ), independent petroleum engineering firms. In this presentation, we make reference to 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. 2

Application of Strengths to Grow Oil Production, Reserves and Value
Phase 1: Form the Base Acquired and farmed-out Delhi, commenced EOR. Phase 2: Positioning for Growth Delhi net proceeds reinvested into shale gas and oil projects. Breakeven cash flow and no earnings. Phase 3: Invest for Growth Delhi and Giddings cash flow reinvested into oil projects and GARP technology. Growing operating cash flow and earnings. Phase 4: Consistent Growth Ongoing development drilling to grow production, reserves and cash flow. Grow the franchise. Negative cash flow and no earnings. 11

Growing Per-Share Value
Oily Texas, Oklahoma or Kansas location Utilizes our horizontal drilling expertise Cost per well ~$3MM Running room with multi-year development Investment sink for Delhi cash flow develop >>1 barrel of oil reserves from 1 barrel of Delhi production 21
Mirando sandstone within previous waterflood Moving from test phase into development phase, despite ongoing challenges in re-injecting produced water Developing 10-20 BOPD per well of long life, low decline production at a cost of $550K per well, or $35K to $68K per net BOPD 3 test producers drilled to date to confirm oil cut and capability of high fluid rate production and injection Goal and upside is in expanding from current 40 drilling locations to similar nearby fields with hundreds of potential drilling locations 22
8,560 net acres Net production ~205 BOEPD from ten wells Proved undeveloped reserves in 11 drilling locations Reserves in Georgetown, Austin Chalk and Buda formations Exposure to new Woodbine oil play Transitional asset, evaluating divestment options due to lack of running room to redeploy Delhi cash flow and >50% gas content 23
Innovation for Increasing Recovery
Reestablishes economic production of the Tail Supplements & enhances existing rod pump Mobilizes remaining fluid to rod pump inlet Successful applications in Giddings Field Two field tests underway Fee/participation for service model 25
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) Cost $75K - $150K per application Patented 26
