3 The Global Coal Markets And Their Impact On NRP

Current Coal Market Exciting time in the coal industry Demand increasing Coal prices continue to improve month over month U.S. coal pricing with global coal World economic indicators point toward higher global coal demand and a supply shortfall Bodes well for U.S. coal industry and NRP 4

5 Coal – Fastest Growing Major Fuel in the World For the 5 th Straight Year – Coal is the fastest growing major fuel in the World Global Coal Consumption for 2007 of 4.5% was well above the ten year average of 3.2% Chinese share of world energy consumption growth in 2007 – 52% Source: BP Statistical Review of World Energy June 2008

6 Global Coal Consumption – Last Five Years Global Coal Consumption increased 32% between 2002 and 2007 China increased ~ 84% India increased ~ 37% Coal consumption has increased in every market around the globe except for the Middle East Source: BP Statistical Review of World Energy June 2008 MM tonnes

7 Coal is on the Move

8 Global Demand and the Domestic Coal Markets China doubled its annual coal production between 2000 and 2007 –Still cannot keep up with demand within China –Has gone from exporter to importer of coal China, India, East Asia and Europe importing coal –High freight rates give U.S. coal into Europe an advantage –Weakness in the U.S. dollar Problems in global coal deliveries creates extremely tight coal market –Australian floods and infrastructure issues –Power shortages in South Africa causing mines to shut down periodically Currently - no excess production in U.S. market Increasing exports boosting U.S. domestic coal prices Swing coals that were being sold into steam market are now going into met market causing shortages in the steam market

Exports Increasing U.S. exports increasing – up 19% in 2007 over 2006 and rising –metallurgical coal at average price of ~ $89 per ton in 2007 –steam coal at average price of ~$48 per ton in 2007 Exports forecasted to increase by approximately 48% in 2008 over 2007 –Steam exports forecasted to increase by approximately 73% –Met exports forecasted to increase by approximately 28% Exports 2007 –Canada and Mexico ~ 35% –Overseas ~65% 9 Source: EIA and COALCAST

11 Recent Announcements – Coal Contracts BHP signs contracts with Japan for $315 per metric tonne for metallurgical coal setting the tone for new contract negotiations around the globe U.S. coal companies 1Q08 conference calls and earnings releases –Alpha, the largest exporter of U.S. metallurgical coal and NRP’s largest met producer After end of 1Q08, secured 2008 contract for 750,000 tons of met coal at $240-$250 per ton at the mine 57% of 2009 planned production is still uncommitted Have sold remainder of 2008 thermal coal (340,000 tons) at $87 per ton –Patriot Coal 5.5 to 6.5 million tons of met coal and 3.5 to 4.5 million tons of thermal coal still uncommitted for 2009 –Arch Coal In Central App., recent metallurgical coal sales approached the Asian market benchmark prices, on a quality adjusted basis. Arch also committed substantial steam coal volumes for 08 and 09 at pricing averaging more than a 40% premium over 1Q08 Source: Company reports and industry trade publications

12 NRP Stands to Benefit

13 NRP Investment Considerations A Proxy for the Coal Industry Landholding company –Lease reserves to coal mining companies –Receive royalty on production based on a % of the gross selling price 2.1 billion tons of coal reserves (22% metallurgical and 78% steam) 66 lessees produce approximately 5% of U.S. production from NRP’s 191 leases Three major coal producing regions in eleven states 2008 estimated production: 57 million tons to 67 million tons Coal royalty accounts for approximately 75% of NRP’s revenue stream Continue to Diversify Income Stream Coal Infrastructure and Transportation Aggregate Royalties Oil and Gas Royalties, Timber, Wheelage and other

NRP - 25% of U.S. Metallurgical Coal Production 2007 U.S. Met Production ~ 52 million tons –Exports 32.2 million tons at an average price of ~$89/ton 2007 NRP Met Production ~ 13 million tons NRP Met Production 1Q08 –28% of NRP’s total production and 37% of NRP’s coal royalty revenue –4.1 million tons –15 Lessees of which 8 are public companies 22% of NRP’s 2.1 billion tons of reserves are metallurgical NRP is highly leveraged to movements in metallurgical coal prices 14 Source: EIA and NRP

15 Historical Performance We believe that NRP’s 2008 financial performance will be better than originally forecasted and shown on this slide Currently do not have sufficient information from our lessees to quantify increase in guidance New guidance to be issued August 11 with 2Q08 earnings Increasing revenue stream provides for growing distributions Total Revenues Distributable Cash Flow 31% CAGR 27% CAGR ? ?

16  Increased distributions last 19 quarters, 93% overall Distributions 93% Distribution Increase Increased Quarterly Distributions

17 Acquisition Opportunities Active acquisition pipeline Right to acquire 3 billion tons of reserves from Cline Resources –Cline currently in the permitting process on three mines in the Illinois Basin –Recently received permit for the Gatling Ohio reserves Our sponsor owns over 20 billion tons of currently non- producing coal that must be offered to NRP when any property reaches a value of $10 million –Currently working on projects in both Montana and North Dakota Agreement with Taggart on coal preparation plants and coal handling facilities Recently increased efforts on Aggregate acquisitions

18 Where are we going next?

Short Term Outlook for Coal Markets World dynamics that would need to change to see lower coal prices –China and India economies would need to slow significantly –Infrastructure problems in both Australia and South Africa need to be resolved –Stronger dollar –Lower freight rates –Lower fuel, steel and labor costs Met prices for 2008, 2009 and 2010 are well positioned to remain strong Global demand and U.S. exports will continue to place upward pressure on domestic coal prices 19

20 Long Term Outlook for the Coal Markets Strong demand next few years EIA expects total U.S. electricity sales to increase 50% by 2030 EIA expects U. S. coal fueled electricity to gain additional market share over the next 25 years growing to approximately 54% by 2030 from 49% today Developing nations around the globe are looking to coal to supply their energy needs creating increasing demand Source: EIA – Energy Information Agency and NRP

Investment Highlights NRP to benefit from robust coal market –Significantly increasing prices for both steam and metallurgical coal –Approximately 28% of 1Q08 production was metallurgical –Highly leveraged to Appalachian and Illinois Basin price increases Nearer term acquisition opportunities –Aggregates –Infrastructure Long term built in growth opportunities associated with Cline Resources and our sponsors 21
