Corporate Presentation March 2011 (NYSE Amex: EPM) © Evolution Petroleum Corporation 1 Forward Looking Statements and Cautionary Note 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, 2010 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 Quick Facts about EPM Ticker Symbol EPM (NYSE AMEX) Fiscal Year-End June 30 Market Cap* ~$208 million as of 2/25/2011 ($7.58/shr) Enterprise Value ~$205 MM Shares 27.5 MM shares outstanding “ (based on 12/31/10 FS) 33.1 MM shares fully diluted ($1.83 avg. exercise) ~42 % owned by institutions Financial Strength ~$3.2 MM in WC & no debt as of 12/31/10 Team Record 7 year track record in creating and implementing major projects * Excluding net value of options and warrants 3 Our Business EPM generates and implements domestic, onshore oil & gas development projects utilizing our expertise and modern technology.

Our technology • Mobilizes remaining fluid to the pump Fluid level at conventional abandonment • Cost $50K - $150K per application • Successfully applied in 3 wells in Giddings Field Remaining potential Reservoir Our Plan for 2011 • Complete first joint venture to install (2 JVs negotiating) • Expand outside of Giddings Field 20 Operating Plan for FY 2011 A $4 million base case capital expenditure program to: Drill up to 5 horizontal wells in Giddings joint venture (3 completed to date) Re-enter and frac Woodford Shale in two mid-depth vertical wells in Haskell (1 to date) and continue Wagoner production testing Commercialize artificial lift technology through one or more joint ventures through demonstrations on third party wells Liquidity Plan: Use Giddings cash flow to cover overhead, and Delhi cash flow to drill Avoid high cost, high risk capital Utilize joint ventures, project financing, noncore asset monetization and/or small, opportunistic equity placement to accelerate development as warranted Maintain liquidity through FY2012 as Delhi cash flows increase 21 Catalysts for growth in FY2011 Continued production growth at Delhi at premium LLS oil price Drilling success in Giddings Positive tests in Woodford Shale New joint venture(s) to apply artificial lift technology Additional development joint venture(s) – Giddings & OK Maintain conservative financial approach while increasing NAV/share – no debt & 84% oil (90% total liquids) 22 Exhibits Definitions EPM Annual Revenues Management team Board of Directors 23 Definitions EOR WAG BOE CF M MM NGL PUD 2P PV10 SEC Reserves Futures Reserves PV10 Futures PV10 Flat PV10 Esc FD Share Enhanced oil recovery Water alternating gas – type of CO2 EOR Barrel of oil equivalent Cubic feet of natural gas at standard conditions Thousands Millions Natural gas liquids Proved undeveloped Proved + Probable Unrisked Reserves Future unescalated pretax net cash flows discounted at 10% per annum based on SEC pricing (trailing twelve months realized prices) Reserves based on unescalated trailing twelve month realized prices Reserves based on five year forward futures commodity prices with subsequent years held constant at the fifth year prices PV10 adjusted for Futures Reserves PV10 adjusted to given commodity prices without escalation PV10 adjusted to given commodity prices with price & cost escalation Fully Diluted Shares includes outstanding shares + unvested options & warrants, without considering the weighted average exercise price of $1.83 Cautionary Note: PV-10 is a commonly used financial metric and does not necessarily equal market value.
