Natural Resource Partners L.P. Investor Meetings West Coast March 19-20, 2007

2 Forward-Looking Statements The statements made by representatives of Natural Resource Partners L.P. (“NRP”) during the course of this presentation that are not historical facts are forward-looking statements. Although NRP believes that the assumptions underlying these statements are reasonable, investors are cautioned that such forward-looking statements are inherently uncertain and necessarily involve risks that may affect NRP’s business prospects and performance, causing actual results to differ from those discussed during the presentation. Such risks and uncertainties include, by way of example and not of limitation: general business and economic conditions; decreases in demand for coal; changes in our lessees’ operating conditions and costs; changes in the level of costs related to environmental protection and operational safety; unanticipated geologic problems; problems related to force majeure; potential labor relations problems; changes in the legislative or regulatory environment; and lessee production cuts. These and other applicable risks and uncertainties have been described more fully in NRP’s 2006 Annual Report on Form 10-K. NRP undertakes no obligation to publicly update any forward-looking statements, whether as a result of new information or future events.

3 NRP – A Lower Risk Proxy for the Coal Industry 2.1 billion tons of coal reserves 70 lessees produce approximately 5% of the US production from our 180 leases Three major coal producing regions in eleven states 2007 estimated production: 60 million tons to 65 million tons (metallurgical – 22% steam – 78%) 2007 estimated total revenues - $222 million to $238 million

4 NRP Financial Profile Market Capitalization ($63 per unit): Enterprise Value: Distribution per Unit (4Q 2006): $2.0 billion $2.5 billion $0.88 quarterly $3.52 annualized Senior Notes (12/31/2006): Drawn on Revolver (12/31/2006): $247 million $214 million Cash on Balance Sheet (12/31/2006): Units Outstanding: (1/16/07): $66 million 32.2 million

5 Diverse Portfolio of Properties Note: Reserve information as of December 31, 2006 – Does not include Cline or Dingess Rum Transactions completed in January. Coal Reserves 2.1 billion tons at 12/31/06 24% Met / 76% Steam 60% Low Sulfur / 36% Compliance States in which NRP has aggregates Coal Producing Basins in U.S. States in which NRP has Coal Reserves Aggregate Reserves 70 million tons

6 Diversity Leads to Stability NRP’s large number of lessees –Diversifies types of operations –Diversifies coal types and qualities –Diversifies customer base –Diversifies revenues Leads to More Stability of Cash Flows Revenue is NOT tied to –One mine –One mining method –One group of miners –One region –One shipper –One customer

7 How NRP Differs from a Coal Producer NRP revenue is tied to a coal miner’s top line revenue Increased mining costs can be NRP’s friend Production cuts at one mine can keep prices higher across the entire industry sector which improves NRP’s top line NRP has no maintenance capital expenditures NRP has low G&A expenses

8 Active Acquisition History Over the last four years Completed 26 acquisitions totaling ~$1.1 billion –Acquired ~ 1.4 billion tons of coal reserves –Acquired overrides on significant additional tonnage –Acquired 5 coal handling and transportation facilities Diversified our portfolio of properties and lessees –Tripled the number of leases –More than doubled the number of lessees –Increased our position in Illinois Basin –Made first purchase of aggregate reserves Established two new growth platforms within the last year –Coal handling and transportation facilities –Aggregates

9 Recent Acquisition History Dingess-Rum 2.4 million common units 92 million tons Jan. 16, 2007 Dec. 18, 2006 Cline 4.46 million Common and Class B units Reserves, Transportation Agreements, and Future Development Opportunities Jan. 4, 2007 D.D.

10 Acquisition Opportunities 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 Right to acquire 3 billions tons of reserves from Cline Resources Deals come to us due to our relationships Agreement with Taggart (formerly Sedgman) on coal preparation plants and coal handling facilities Opportunities in other qualified asset classes

11  Increased distributions 15 out of 16 quarters since IPO, 72% overall Distributions 72% Distribution Increase Increased Quarterly Distributions

12 Short Term Outlook for Domestic Coal Market Because of the abnormal weather, utility stockpiles are at normal levels resulting in short term spot market pricing pressure –However, very little coal is sold on the spot market Most of NRP’s coal is sold by our lessees under long term contracts In the 4th quarter NRP lessees had higher prices in every single region within Appalachia as well as the Illinois Basin due to contract rollovers

13 Long Term Outlook for the Coal Markets New coal demand will be generated by: –New coal-fired power plants being planned –New coal uses coal gasification coal to liquids EIA expects total electricity sales to increase by 50% by 2030 EIA expects coal fueled electricity to gain additional market share over the next 25 years growing to approximately 57% by 2030 from 50% today New demand for higher sulfur coal due to the large number of scrubbers being added to exiting power plants EIA – Energy Information Agency

14 Investment Highlights Attractive portfolio of long-life, diverse properties Lease to operators with diverse customer base Distribution supported by stable, royalty-based cash flows No direct exposure to mining operating costs or risks Well-positioned for growth via coal and mineral acquisitions Demonstrated ability to grow asset base and distributions Coal royalty revenues are taxed at capital gains rates A lower risk proxy for the coal industry Two new growth platforms in addition to coal reserves
