That Schedule 13D is hereby amended as set forth below. ITEM 4. PURPOSE OF TRANSACTION The text of Item 4 is hereby amended by adding the following language: On August 9, 2005, the Partnership and the Issuer entered into an underwriting agreement (the "Underwriting Agreement") with Lehman Brothers Inc. and Citigroup Global Markets Inc. as representatives of several underwriters (the "Underwriters") providing for the sale by the Partnership of 4,200,000 subordinated units representing limited partner interests of the Issuer (the "Subordinated Units") owned by the Partnership and the 4,200,000 common units representing limited partner interests of the Issuer issuable upon the conversion of the Subordinated Units (the "Common Units", collectively with the Subordinated Units, the "Units"). The Partnership sold the 4,200,000 Units to the Underwriters at a price of $57.95 per Unit, and the Underwriters resold the Units to the public pursuant to a registration statement on Form S-3 (the "Registration Statement") at a price of $61.00 per Unit. The transaction closed on August 15, 2005. The Registration Statement was filed with the Securities and Exchange Commission and has been declared effective. This Amendment No. 1 to Schedule 13D shall not constitute an offer to sell or the solicitation of an offer to buy nor shall there be any sale of the Units in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such state. The offering is being made only by means of a prospectus. A written prospectus meeting the requirements of Section 10 of the Securities Act of 1933 may be obtained at no cost by writing or calling the Issuer at the following address: Investor Relations Department Natural Resource Partners L.P. 601 Jefferson, Suite 3600 Houston, Texas 77002 (713) 751-7507 9 ITEM 5.
