2. 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.

8. 8 Coal Reserves

9. 9 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
