4 Demand for U.S. coal is expected to be at least 30 million tons lower in 2009 Low-priced natural gas continues to displace utility coal burn in certain U.S. regions Certain U.S. coal exported in 2008 will shift to U.S. markets in 2009 U.S. coals not currently competitive in European market Stronger U.S. dollar & reduced vessel rates expand Australia's competitive reach Idling by steel companies has hurt met coal demand in the short-term, but will help protect against large oversupply of steel inventory Lower met demand is pushing crossover coals into the thermal market Labor shortages have abated at Central Appalachian mines Coal producers are closing mines and announcing production cuts in response to decreased demand Short-Term Coal Markets Global recession has reduced economic growth & demand for commodities

5 Weekly U.S. Electricity Generation ___________________________ Source: EEI Eastern U.S. electricity markets have seen minimal impact from the economic downturn

6 Natural Gas vs. Coal Dispatch Cost Coal is expected to return to its long-term position as the lowest cost fossil fuel

7 Coal-to-Gas Switching in the Southeast 7.0 million tons lost since January 2008 ___________________________ Source: Genscape

8 Weekly U.S. Steel Production After plummeting in Q4 '08, steel production appears to have bottomed

9 Coal Supply Response Producers have quickly reduced production to match demand Expected 2009 production decrease (million tons)

10 Purchasing Managers Index as a Leading Indicator PMI has been an accurate leading indicator for the last six U.S. recoveries

11 The end of the global recession will likely mark the return of strong energy & steel demand China and India continue to drive worldwide demand Nearly 19.3 GW of new coal-fueled generating capacity are currently under construction in the U.S. Supply constraints will limit production gains & pose barriers to entry Permit challenges Added safety regulations Depleting reserves, more difficult geology Coal is the most abundant fuel for lowest cost generation Long-Term Coal Markets Long-term fundamentals remain strong

12 Nearly 19.3 GW of new coal-fueled capacity is under construction New U.S. Coal-Fueled Generation Capacity

13 Energy-related proposals in the stimulus package Appointees to key policy-making positions Positions and impact of the newly-created White House energy czar Resolution of lease expirations affecting oil & gas exploration rights Interpretations of the Clean Air Act Supreme Court rulings potentially defining carbon dioxide as a pollutant U.N.

18 Production & reserve base in close proximity to coal-fueled plants Coal Products to Serve Key Markets Patriot's areas of operation

19 The Current Situation The global economic situation has created an unpredictable business environment Financial pressures on customers, suppliers and other stakeholders may result in unexpected short-term actions Unprecedented volatility in commodity prices is affecting the input costs of our production, as well as the prices and sales volumes of our products Management has unwound expansion plans and altered other decisions that were very sound just a few months ago The pace of change in this business environment is very rapid

20 Transformation of Patriot Strategic review of each property Mining cost Mining predictability Coal quality Profit margins Idling of Black Oak metallurgical mine Idling of high-cost Jupiter & Remington properties Continued development of low-cost thermal operations Hill Fork - CAPP surface mine Blue Creek - CAPP underground mine Deferral of other planned mine projects & expansions Positioning Patriot as a more competitive long-term coal supplier

21 Management Action Plan Close high-cost mines Develop low-cost properties Reduce capital expenditures Redeploy equipment to more productive locations Reduce material & supply costs Fill open positions with displaced miners from idled operations Operational initiatives

22 Management Action Plan Restructuring of below-market legacy coal supply agreements Customer reimbursements for changes in laws Optimization of product mix & contract terms for new sales transactions Monetization of non-strategic coal reserves Commercial initiatives

23 Estimated sales volumes of 36 to 38 million tons Currently priced production Tons Price per Ton Appalachia - Thermal 22.3 $ 57 Appalachia - Met 4.9 $108 Illinois Basin 7.8 $ 38 Unpriced production Thermal - Up to 1.0 million tons Met - Up to 2.0 million tons 2009 Guidance Patriot is largely contracted for 2009

24 Projected cost per ton Appalachia $56 - 59 Illinois Basin $35 - 37 Capital expenditures between $100 and $125 million 2009 Guidance Management is reducing expenses & capital
