Natural Resource Partners L.P. Investor Meetings New York and Boston May 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.

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 27 acquisitions totaling ~$1.1 billion Diversified our portfolio of properties and lessees Established two new growth platforms within the last year

11  Increased distributions 16 out of 17 quarters since IPO, 78% overall Distributions 78% Distribution Increase Increased Quarterly Distributions Distributions have been adjusted for the April 07 two-for-one unit split

12 Short Term Outlook for Domestic Coal Market Short-term spot market prices have stabilized and begun to increase –However, very little coal is sold on the spot market Most of NRP’s coal is sold by our lessees under long term contracts Lessees are reporting improving term prices Met coal prices continue to be strong

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
