2 Forward-Looking Statements, Risk Factors and Non-GAAP Financial Measures Some of the information in this presentation may contain forward-looking statements. These statements can be identified by the use of forward-looking terminology including "will," "may," "believe," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of financial condition or of results of operations, or state other "forward-looking" information. These forward-looking statements involve risks and uncertainties. When considering these forward-looking statements, you should keep in mind the risk factors and other cautionary statements in our prospectus dated July 13, 2010. Forward-looking statements are not guarantees of future performance or an assurance that our current assumptions or projections are valid. Actual results may differ materially from those projected. You are strongly encouraged to closely consider the additional disclosures contained in our prospectus, including the risk factors beginning on page 23 thereof. You may access a copy of our prospectus at www.oxfordresources.com. In this presentation, we present Adjusted EBITDA, a non-GAAP financial measure that we use in our business as it is an important supplemental measure of our performance. We believe Adjusted EBITDA provides useful information to investors to assess (i) our financial performance without regard to financing methods, capital structure or income taxes; (ii) our ability to generate cash sufficient to pay interest on our indebtedness and to make distributions to our unitholders and our general partner; (iii) our compliance with certain financial covenants applicable to our credit facility; and (iv) our ability to fund capital expenditure projects from operating cash flow. Adjusted EBITDA represents net income (loss) attributable to our unitholders before interest, taxes, DD&A, gain from purchase of business, contract termination and amendment expenses, net, amortization of below-market coal sales contracts, non-cash equity compensation expense, non-cash gain or loss on asset disposals and the change in the fair value of our future ARO. Adjusted EBITDA should not be considered an alternative to net income (loss) attributable to our unitholders, income from operations, cash flows from operating activities or any other measure of performance presented in accordance with GAAP. Adjusted EBITDA excludes some, but not all, items that affect net income (loss) attributable to our unitholders, income from operations and cash flows, and these measures may vary among other companies. Therefore, Adjusted EBITDA as presented in this presentation may not be comparable to similarly titled measures of other companies.

6 Strategic Regional System of Assets

7 Coal is the Dominant Fuel Source in our Market Source: EIA and J.T. Boyd. We market the majority of the coal we produce to base-load, scrubbed power plants Coal fuels, on average, nearly 70% of electricity generation in our market versus 38% for the rest of the U.S. Outlook for steam coal in our market is strong % Coal-Fired Generation by States in Our Primary Market Area

8 Our Region Expected to Offset CAPP Declines Central Appalachia ("CAPP") steam coal supply declines due to: Regulatory / permitting environment Increased operating costs Reserve depletion Increasingly complex geology Increased exports Steam-to-met switching Regional Production Forecasts CAPP Coal Shipments to Power Plants Source: EIA and J.T. Boyd. (Tons in millions) Down 54% Up 36% Up 43%

9 Lower Risk / Cost Surface Mining We deploy some of the largest equipment east of the Mississippi River Highwall miner and auger technologies lower costs and increase recoverable tons Experienced, non-union workforce with minimal legacy liabilities No mountaintop removal mining required for NAPP and ILB operations Location of infrastructure and river terminals reduces transportation costs
