Ladies and Gentlemen:

Natural Resource Partners L.P., a limited partnership organized under the laws of Delaware (the “Partnership”), and NRP Finance Corporation, a corporation organized under the laws of Delaware (the “Co-Issuer” and, together with the Partnership, the “Issuers”), propose to issue and sell to the several parties named in Schedule I hereto (the “Initial Purchasers”), for whom you are acting as representative (the “Representative”), $105,000,000 principal amount of their 9.125% Senior Notes due 2018 (the “Securities”). The Securities are to be issued under an indenture (the “Indenture”), dated September 18, 2013, between the Issuers and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The Issuers have previously issued $300,000,000 in aggregate principal amount of their 9.125% Senior Notes due 2018 (the “Existing Notes”) under the Indenture on September 18, 2013. The Securities constitute Additional Notes (as such term is defined in the Indenture) under the Indenture. Except as otherwise disclosed in the Disclosure Package and the Final Memorandum (as such terms are defined below), the Securities will have terms identical to the Existing Notes and will be treated as a single series of debt securities for all purposes under the Indenture.

The Securities will have the benefit of a registration rights agreement (the “Registration Rights Agreement”) to be dated as of the Closing Date (as defined below), among the Issuers and the Initial Purchasers, pursuant to which the Issuers will agree to file with the Commission (as defined below) (i) a registration statement under the Act (as defined below), relating to another series of debt securities of the Issuers with terms substantially identical to the Securities (the “Exchange Securities”) to be offered in exchange for the Securities (the “Exchange Offer”), and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Act relating to the resale by certain holders of the Securities, and, in each case, to use their commercially reasonable efforts to cause such registration statements to be declared effective. The use of the neuter in this purchase agreement (this “Agreement”) shall include the feminine and masculine wherever appropriate. Certain terms used herein are defined in Section 22 hereof.

GP Natural Resource Partners LLC, a Delaware limited liability company (the “Managing General Partner”), is the general partner of NRP (GP) LP, a Delaware limited partnership (the “General Partner”), which in turn is the general partner of the Partnership. The Partnership owns its subsidiaries, other than the Co-Issuer and NRP Oil and Gas LLC, a Delaware limited liability company (“NRP Oil and Gas”), through a wholly owned operating company, NRP (Operating) LLC, a Delaware limited liability company (the “Operating Company”).

On October 6, 2014, NRP Oil and Gas entered into a definitive purchase and sale agreement to acquire certain non-operated working interests in oil and gas assets located in the Bakken/Three Forks play from an affiliate of Kaiser-Francis Oil Company in exchange for approximately $340.0 million in cash, subject to customary purchase price adjustments (the “Kaiser-Francis Acquisition”).

The sale of the Securities to the Initial Purchasers will be made without registration of the Securities under the Act in reliance upon exemptions from the registration requirements of the Act.

In connection with the sale of the Securities, the Issuers have prepared a preliminary offering memorandum, dated October 6, 2014 (as amended or supplemented at the date thereof, including any and all exhibits thereto and any information incorporated by reference therein, the “Preliminary Memorandum”), and a final offering memorandum, dated October 9, 2014 (as amended or supplemented at the Execution Time (as defined below), including any and all exhibits thereto and any information incorporated by reference therein, the “Final Memorandum”).

Each of the Issuers hereby confirms that they have authorized the use of the Disclosure Package, the Preliminary Memorandum and the Final Memorandum, and any amendment or supplement thereto, in connection with the offer and sale of the Securities by the Initial Purchasers.

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the “Act”), and may not be offered or sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of their distribution at any time or (ii) otherwise until 40 days after the later of the commencement of the offering and the date of closing of the offering, except in either case in accordance with Regulation S or Rule 144A under the Act. Terms used in this paragraph have the meanings given to them by Regulation S.”

5. Agreements. The Issuers agree with each Initial Purchaser that:

(a) The Issuers will furnish to each Initial Purchaser and to counsel for the Initial Purchasers, without charge, during the period referred to in Section 5(d) hereof, as many copies of the materials contained in the Disclosure Package and the Final Memorandum and any amendments and supplements thereto as they may reasonably request.

(b) The Issuers will prepare a final term sheet, containing a description of final terms of the Securities and the offering thereof, in the form approved by you and attached as Schedule II hereto.

(c) The Issuers will not amend or supplement the Disclosure Package or the Final Memorandum without the prior written consent of the Representative.

- 13 -

(d) If at any time prior to the completion of the sale of the Securities by the Initial Purchasers (as determined by the Representative), any event occurs as a result of which the Disclosure Package or the Final Memorandum, as then amended or supplemented, would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made or the circumstances then prevailing, not misleading, or if it should be necessary to amend or supplement the Disclosure Package or the Final Memorandum to comply with applicable law, the Issuers will promptly (i) notify the Representative of any such event; (ii) subject to the requirements of Section 5(c) hereof, prepare an amendment or supplement that will correct such statement or omission or effect such compliance; and (iii) supply any supplemented or amended Disclosure Package or Final Memorandum to the several Initial Purchasers and counsel for the Initial Purchasers without charge in such quantities as they may reasonably request.

(e) Without the prior written consent of the Representative, the Issuers have not given and will not give to any prospective purchaser of the Securities any written information concerning the offering of the Securities other than materials contained in the Disclosure Package, the Final Memorandum or any other offering materials prepared by or with the prior written consent of the Representative.

(f) The Issuers will arrange, if necessary, for the qualification of the Securities for sale by the Initial Purchasers under the laws of such jurisdictions as the Representative may designate (including certain provinces of Canada) and will maintain such qualifications in effect so long as required for the sale of the Securities; provided that in no event shall the Issuers be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject. The Issuers will promptly advise the Representative of the receipt by the Issuers of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(g) The Issuers will not, and will not permit any of their Affiliates to, resell any Securities that have been acquired by any of them.

(h) None of the Issuers, their Affiliates, or any person acting on the Issuers’ or their Affiliates’ behalf (other than the Initial Purchasers, as to whom no covenant is given) will, directly or indirectly, make offers or sales of any security, or solicit offers to buy any security, under circumstances that would require the registration of the Securities under the Act.

(i) None of the Issuers, their Affiliates, or any person acting on the Issuers’ or their Affiliates’ behalf (other than the Initial Purchasers, as to whom no covenant is given) will engage in any directed selling efforts (within the meaning of Regulation S) with respect to the Securities; and each of them will comply with the offering restrictions requirement of Regulation S.

(j) None of the Issuers, their Affiliates, or any person acting on the Issuers’ or their Affiliates’ behalf (other than the Initial Purchasers, as to whom no covenant is given) will engage in any form of general solicitation or general advertising (within the meaning of Regulation D) in connection with any offer or sale of the Securities in the United States.

- 14 -

(k) For so long as any of the Securities are outstanding and are “restricted securities” within the meaning of Rule 144(a)(3) under the Act, the Partnership, during any period in which it is not subject to and in compliance with Section 13 or 15(d) of the Exchange Act or it is not exempt from such reporting requirements pursuant to and in compliance with Rule 12g3-2(b) under the Exchange Act, will provide to each holder of such restricted securities and to each prospective purchaser (as designated by such holder) of such restricted securities, upon the request of such holder or prospective purchaser, any information required to be provided by Rule 144A(d)(4) under the Act. This covenant is intended to be for the benefit of the holders, and the prospective purchasers designated by such holders, from time to time of such restricted securities.

(l) The Issuers will cooperate with the Representative and use its best efforts to permit the Securities to be eligible for clearance and settlement through The Depository Trust Company.

(m) Each of the Securities will bear the legend contained in “Notice to Investors” in the Preliminary Memorandum and the Final Memorandum for the time period and upon the other terms stated therein.

(n) Other than the $20.0 million principal amount of contemporaneously issued notes of the same series, the Issuers will not for a period of 60 days following the Execution Time, without the prior written consent of the Representative, offer, sell, contract to sell, pledge, otherwise dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Issuers or any person in privity with the Issuers, directly or indirectly, or announce the offering, of any debt securities issued or guaranteed by either of the Issuers (other than the Securities and the Exchange Securities).

(o) The Issuers will not take, directly or indirectly, any action designed to, or that has constituted or that might reasonably be expected to, cause or result, under the Exchange Act or otherwise, in stabilization or manipulation of the price of any security of either the Partnership or the Co-Issuer to facilitate the sale or resale of the Securities.

(p) The Partnership will, for a period of twelve months following the Execution Time, furnish to the Representative (i) all reports or other communications (financial or other) generally made available to its shareholders, and deliver such reports and communications to the Representative as soon as they are available, unless such documents are furnished to or filed with the Commission or any securities exchange on which any class of securities of the Partnership is listed and generally made available to the public and (ii) such additional information concerning the business and financial condition of the Partnership as the Representative may from time to time reasonably request (such statements to be on a consolidated basis to the extent the accounts of the Partnership and its subsidiaries are consolidated in reports furnished to its shareholders).

(q) The Issuers agree to pay the costs and expenses relating to the following matters: (i) the preparation of the Registration Rights Agreement and the issuance of the Securities, the Exchange Securities and the fees and expenses of the Trustee and any paying agent (including related fees and expenses of any counsel to such parties); (ii) the preparation,

- 15 -

printing or reproduction of the materials contained in the Disclosure Package and the Final Memorandum and each amendment or supplement to either of them; (iii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the materials contained in the Disclosure Package and the Final Memorandum, and all amendments or supplements to either of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iv) the issuance and delivery of the Securities or the Exchange Securities; (v) any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (vi) the printing (or reproduction) and delivery of the Transaction Documents, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities or Exchange Securities; (vii) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states, the provinces of Canada and any other jurisdictions specified pursuant to Section 5(f) (including filing fees and the reasonable fees and expenses of counsel for the Initial Purchasers relating to such registration and qualification); (viii) the transportation and other expenses incurred by or on behalf of representatives of the Issuers in connection with presentations to prospective purchasers of the Securities; and (ix) all other costs and expenses incident to the performance by the Issuers of their obligations hereunder.

6. Conditions to the Obligations of the Initial Purchasers. The obligations of the Initial Purchasers to purchase the Securities shall be subject to the accuracy of the representations and warranties of the Issuers contained herein at the Execution Time and the Closing Date, to the accuracy of the statements of the Issuers made in any certificates pursuant to the provisions hereof, to the performance by the Issuers of their obligations hereunder and to the following additional conditions:

(a) The Issuers shall have requested and caused (i) Vinson & Elkins LLP, counsel for the Issuers, to furnish to the Representative its opinion and negative assurance letter, dated the Closing Date and addressed to the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, to the effect set forth in Annex B hereto and (ii) Kathryn S. Wilson, general counsel for the Issuers, to furnish to the Representative her opinion, dated the Closing Date and addressed to the Initial Purchasers, in form and substance reasonably satisfactory to the Initial Purchasers, to the effect set forth in Annex C hereto.

(b) The Representative shall have received from Andrews Kurth LLP, counsel for the Initial Purchasers, such opinion and negative assurance letter, dated the Closing Date and addressed to the Initial Purchasers, with respect to the issuance and sale of the Securities, the Indenture, the Registration Rights Agreement, the Disclosure Package, the Final Memorandum (as amended or supplemented at the Closing Date) and other related matters as the Representative may reasonably require, and the Issuers shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

(c) The Managing General Partner shall have furnished to the Representative a certificate of the Managing General Partner, signed by (x) the Chairman of the Board or the President and (y) the principal financial or accounting officer of the Managing General Partner, dated the Closing Date, to the effect that the signers of such certificate have carefully examined the Disclosure Package and the Final Memorandum and any supplements or amendments thereto, and this Agreement and that:

- 16 -

(i) the representations and warranties of the Issuers in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date, and the Issuers have complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; and

(ii) since the date of the most recent financial statements included in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto), there has been no material adverse change in the condition (financial or otherwise), prospects, earnings, business or properties of the Partnership and its subsidiaries, taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

(d) At the Execution Time and at the Closing Date, the Issuers shall have requested and caused Ernst & Young LLP to furnish to the Representative a “comfort letter,” dated as of the Execution Time, and a bring down comfort letter, dated as of the Closing Date, in form and substance satisfactory to the Representative, confirming that they are independent accountants within the meaning of the Exchange Act and the applicable published rules and regulations thereunder and confirming certain matters with respect to the audited and unaudited financial statements and other financial and accounting information of the Partnership and its consolidated subsidiaries contained in or incorporated by reference in the Disclosure Package and Final Memorandum, including any amendment or supplement thereto as of the date of the applicable letter.

All references in this Section 6(d) to the Preliminary Memorandum and the Final Memorandum include any amendment or supplement thereto at the date of the applicable letter.

(e) At the time of execution of this Agreement, the Initial Purchasers shall have received from the Partnership a copy of an oversight review letter from Netherland, Sewell & Associates, Inc., independent petroleum engineers, prepared on behalf of the Partnership, with respect to the estimates prepared by Kaiser-Francis Oil Company of the proved reserves of the Kaiser-Francis Acquisition.

(f) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Disclosure Package (exclusive of any amendment or supplement thereto) and the Final Memorandum (exclusive of any amendment or supplement thereto), there shall not have been (i) any material change or decrease specified in the letter or letters referred to in paragraph (d) of this Section 6; or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), prospects, earnings, business or properties of the Partnership and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement

- 17 -

thereto), the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representative, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

(g) The Securities shall be eligible for clearance and settlement through The Depository Trust Company.

(h) Prior to the Closing Date, the Issuers shall have furnished to the Representative such further information, certificates and documents as the Representative may reasonably request.

Notice of such cancellation shall be given to the Issuers in writing or by telephone or facsimile confirmed in writing.

The documents required to be delivered by this Section 6 will be delivered at the office of Andrews Kurth LLP, counsel for the Initial Purchasers, at 600 Travis Street, Suite 4200, Houston, Texas, 77002 on the Closing Date.

7. Reimbursement of Expenses. Subject to Section 5(q) hereof, if the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Initial Purchasers set forth in Section 6 hereof is not satisfied or because of any refusal, inability or failure on the part of the Issuers to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Initial Purchasers, the Issuers will reimburse the Initial Purchasers severally through Wells Fargo on demand for all expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8. Indemnification and Contribution. (a) The Issuers agree to indemnify and hold harmless each Initial Purchaser, the directors, officers, employees, Affiliates and agents of each Initial Purchaser and each person who controls any Initial Purchaser within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other U.S. federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities or actions in respect thereof arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the

- 18 -

Preliminary Memorandum, the Final Memorandum, any Issuer Written Information (as defined below) or any other written information used by or on behalf of the Issuers in connection with the offer or sale of the Securities or any contemporaneously issued notes of the same series, or in any amendment or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by it in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Issuers will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Memorandum or the Final Memorandum, or in any amendment thereof or supplement thereto, in reliance upon and in conformity with written information furnished to the Issuers by or on behalf of any Initial Purchaser through the Representative specifically for inclusion therein. This indemnity agreement will be in addition to any liability that the Issuers may otherwise have.

(b) Each Initial Purchaser severally, and not jointly, agrees to indemnify and hold harmless the Issuers, each of their directors, each of their officers, and each person who controls the Issuers within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity to each Initial Purchaser, but only with reference to written information relating to such Initial Purchaser furnished to the Issuers by or on behalf of such Initial Purchaser through the Representative specifically for inclusion in the Preliminary Memorandum or the Final Memorandum (or in any amendment or supplement thereto). This indemnity agreement will be in addition to any liability that any Initial Purchaser may otherwise have. The Issuers acknowledge that the statements set forth under the heading “Plan of Distribution” in the second and third sentences of the sixth paragraph and the seventh paragraph in the Preliminary Memorandum and the Final Memorandum constitute the only information furnished in writing by or on behalf of the Initial Purchasers for inclusion in the Preliminary Memorandum or the Final Memorandum or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel (including local counsel) of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel, other than local counsel if not appointed by the indemnifying party, retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel (including local counsel) to represent the indemnified party in an action, the

- 19 -

indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of not more than one such counsel (plus separate local counsel) if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest; (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party; (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action; or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Issuers and the Initial Purchasers severally agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending any loss, claim, damage, liability or action) (collectively “Losses”) to which the Issuers and one or more of the Initial Purchasers may be subject in such proportion as is appropriate to reflect the relative benefits received by the Issuers on the one hand and by the Initial Purchasers on the other from the offering of the Securities and any contemporaneously issued notes of the same series; provided, however, that in no case shall any Initial Purchaser be responsible for any amount in excess of the purchase discount or commission applicable to the Securities purchased by such Initial Purchaser hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Issuers and the Initial Purchasers severally shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Issuers on the one hand and the Initial Purchasers on the other in connection with the statements or omissions that resulted in such Losses, as well as any other relevant equitable considerations. Benefits received by the Issuers shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by them, and benefits received by the Initial Purchasers shall be deemed to be equal to the total purchase discounts and commissions. Relative fault shall be determined by reference to, among other things, whether any untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Issuers on the one hand or the Initial Purchasers on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Issuers and the Initial Purchasers agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation that does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was

- 20 -

not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls an Initial Purchaser within the meaning of either the Act or the Exchange Act and each director, officer, employee, Affiliate and agent of an Initial Purchaser shall have the same rights to contribution as such Initial Purchaser, and each person who controls the Issuers within the meaning of either the Act or the Exchange Act and each officer and director of the Issuers shall have the same rights to contribution as the Issuers, subject in each case to the applicable terms and conditions of this paragraph (d).

9. Default by an Initial Purchaser. If any one or more Initial Purchasers shall fail to purchase and pay for any of the Securities agreed to be purchased by such Initial Purchaser hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Initial Purchasers shall be obligated severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule I hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Initial Purchasers) the Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule I hereto, the remaining Initial Purchasers shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Initial Purchasers do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Initial Purchaser or the Issuers. In the event of a default by any Initial Purchaser as set forth in this Section 9 the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representative shall determine in order that the required changes in the Final Memorandum or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Initial Purchaser of its liability, if any, to the Issuers or any nondefaulting Initial Purchaser for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representative, by notice given to the Issuers prior to delivery of and payment for the Securities, if at any time prior to such time (a) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such exchange; (b) a banking moratorium shall have been declared either by U.S. federal or New York State authorities; or (c) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Representative, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated in the Disclosure Package and the Final Memorandum (exclusive of any amendment or supplement thereto).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Issuers or its officers and of the Initial Purchasers set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Initial Purchasers or the Issuers or any of the indemnified persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

- 21 -

12. Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Representative, will be mailed, delivered or telefaxed (with the receipt of any such fax to be confirmed by telephone) to the Representative at Wells Fargo Securities, LLC, 550 S.

13. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the indemnified persons referred to in Section 8 hereof and their respective successors, and, except as expressly set forth in Section 5(k) hereof, no other person will have any right or obligation hereunder.

14. Jurisdiction. The Issuers agree that any suit, action or proceeding against the Issuers brought by any Initial Purchaser, the directors, officers, employees and agents of any Initial Purchaser, or any person who controls any Initial Purchaser, arising out of or based upon this Agreement or the transactions contemplated hereby may be instituted in any state or U.S. federal court in The City of New York and County of New York, and waives any objection which they may now or hereafter have to the laying of venue of any such proceeding, and irrevocably submits to the jurisdiction of such courts in any suit, action or proceeding.

15. Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) among the Issuers and the Initial Purchasers, or any of them, with respect to the subject matter hereof.

16. Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.

17. Waiver of Jury Trial. The Issuers hereby irrevocably waive, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

18. No Fiduciary Duty. The Issuers hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers, on the one hand, and the Initial Purchasers and any Affiliate through which it may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Issuers and (c) the Issuers’ engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Issuers agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Issuers on related or other matters). The Issuers agree that they will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuers, in connection with such transaction or the process leading thereto.

- 22 -

19. Waiver of Tax Confidentiality.

Ladies and Gentlemen:

This letter is provided to you pursuant to Section 6(a)(i) of the Purchase Agreement, dated October 9, 2014 (the “Purchase Agreement”), by and among Natural Resource Partners L.P., a Delaware limited partnership (the “Partnership”), and NRP Finance Corporation, a Delaware corporation (the “Co-Issuer,” and together with the Partnership, the “Issuers”), and Wells Fargo Securities, LLC, as representative of the several initial purchasers named in Schedule I thereto (the “Initial Purchasers”), pursuant to which the Issuers have agreed to issue and sell to the Initial Purchasers, and the Initial Purchasers have agreed to purchase from the Issuers, $105,000,000 in aggregate principal amount of 9.125% Senior Notes due 2018 (the “Securities”). The Securities are to be issued under an indenture (the “Indenture”), dated September 18, 2013, between the Issuers and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The Issuers have previously issued $300,000,000 in aggregate principal amount of their 9.125% Senior Notes due 2018 under the Indenture on September 18, 2013. Any capitalized term used in this letter and not defined herein shall have the meaning assigned to such term in the Purchase Agreement.

We have acted as counsel to the Issuers in connection with the offer and sale by the Issuers of the Securities. In connection with the matters set forth below, we have examined and relied upon the following:

(vii) copies of letters or certificates of recent dates received by us from public officials in the State of Delaware as to the due formation or organization and valid existence and good standing of the members of the Partnership Group;

(viii) reports, dated as of recent dates, purporting to describe all financing statements on file as of the dates specified therein in the office of the Secretary of State of the State of Delaware naming the Managing General Partner, the General Partner, the Partnership, the Co-Issuer, the Operating Company, Adena Minerals LLC (“Adena Minerals”), Western Pocahontas Properties Limited Partnership (“WPP”), Great Northern Properties Limited Partnership (“Great Northern”) or Robertson Coal Management LLC (“RCM”) as debtor;

(ix) the preliminary offering memorandum, dated October 6, 2014 (the “Preliminary Memorandum”);

(x) the pricing supplement to the Preliminary Memorandum, dated October 9, 2014 (the “Pricing Supplement,” and together with the Preliminary Memorandum, the “Disclosure Package”);

ANNEX C

LEGAL OPINION OF KATHRYN S. WILSON

WELLS FARGO SECURITIES, LLC

As representative of the

several Initial Purchasers named

in Schedule I to the

Purchase Agreement

c/o WELLS FARGO SECURITIES, LLC

550 S. Tryon Street

Charlotte, North Carolina 28202

Ladies and Gentlemen:

I am the Vice President, General Counsel and Secretary of GP Natural Resource Partners LLC, a Delaware limited liability company, the general partner of NRP (GP) LP, a Delaware limited partnership, the general partner of Natural Resource Partners L.P., a Delaware limited partnership (the “Partnership”). I am furnishing this letter to you pursuant to Section 6(a)(ii) of the Purchase Agreement, dated October 9, 2014 (the “Purchase Agreement”), by and among the Partnership, NRP Finance Corporation, a Delaware corporation (the “Co-Issuer,” and together with the Partnership, the “Issuers”), and Wells Fargo Securities, LLC, as representative of the several initial purchasers named in Schedule I thereto (the “Initial Purchasers”), pursuant to which the Issuers have agreed to issue and sell to the Initial Purchasers, and the Initial Purchasers have agreed to purchase from the Issuers, $105,000,000 in aggregate principal amount of 9.125% Senior Notes due 2018 (the “Securities”). The Securities are to be issued under an indenture (the “Indenture”), dated September 18, 2013, between the Issuers and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The Issuers have previously issued $300,000,000 in aggregate principal amount of their 9.125% Senior Notes due 2018 under the Indenture on September 18, 2013. Any capitalized term used in this opinion and not defined herein shall have the meaning assigned to such term in the Purchase Agreement.

In connection with the opinions and statements set forth below, I or members of my staff or others under my supervision have examined and relied upon the following:

(ii) copies of letters or certificates of recent dates received by me from public officials in those jurisdictions for each member of the Partnership Group, as set forth in Annex I attached hereto, as to the due qualification to do business as a foreign entity and good standing;

(iii) the preliminary offering memorandum, dated October 6, 2014 (the “Preliminary Memorandum”);

(iv) the pricing supplement to the Preliminary Memorandum, dated October 9, 2014, the (“Pricing Supplement,” and together with the Preliminary Memorandum, the “Disclosure Package”);

(v) the offering memorandum, dated October 9, 2014 (the “Final Memorandum”);

(vi) such other documents and records as I have deemed necessary or advisable for purposes of the opinions expressed and statements set forth below.

Also, in connection with this letter, I, or other attorneys under my supervision, have (i) investigated such questions of law, (ii) examined such corporate documents and records of certain members of the Partnership Group and certificates of public officials, and (iii) received such information from officers and representatives of certain members of the Partnership Group and made such investigations as I, or other attorneys under my supervision, have deemed necessary or appropriate for the purposes of this letter. Except as otherwise expressly stated below, I have not, nor have other attorneys under my supervision, conducted independent investigations or inquiries to determine the existence of matters, actions, proceedings, items, documents, facts, judgments, decrees, franchises, certificates, permits or the like and have made no independent search of the records of any court, arbitrator, or governmental authority affecting any person, and no inference as to my knowledge thereof shall be drawn from the fact of my representation of any party or otherwise.

Based on the foregoing and subject to the qualifications and limitations set forth herein, I am of the opinion that:

(a) Each member of the Partnership Group is duly registered or qualified as a foreign limited liability company, corporation or limited partnership, as the case may be, for the transaction of business under the laws of each jurisdiction in which the ownership or lease of property or the character of the business conducted by it makes such qualification or registration necessary, except where the failure so to register or qualify would not have a Material Adverse Effect.

(b) To my knowledge, (i) there are no legal or governmental proceedings pending or threatened against any member of the Partnership Group or to which any member of the Partnership Group is a party or to which any of their respective properties is subject that are required to be described in the Final Memorandum but are not so described as required and (ii) there are no agreements, contracts, indentures, leases or other instruments that are required to be described in the Disclosure Package or the Final Memorandum that are not described but are required to be described in the Partnership’s periodic reports.

C-2

In rendering the opinions expressed and statements set forth herein, I have:

(A) relied, without independent investigation or verification, in respect of matters of fact upon certificates of officers and employees of the Partnership Group and upon information obtained from public officials; and

(B) assumed that all documents submitted to me as originals are authentic, that all copies submitted to me conform to the originals thereof, and that the signatures on all documents examined by me are genuine.

I am licensed to practice law in the State of Texas, and the opinions set forth herein are limited to matters governed by the laws of the State of Texas, applicable federal law, the Delaware LP Act, the Delaware General Corporation Law and the Delaware LLC Act, in each case as currently in effect, and I express no opinion as to the law of any other jurisdiction. I do not express any opinion with respect to state or local taxes or tax statutes to which any of the limited partners of the Partnership or any of the members of the Partnership Group may be subject.

Qualification of any statement or opinion herein by use of the words “to my knowledge” means that no information has come to my attention, or to the attention of attorneys reporting to me, that would give me or such attorneys actual knowledge of facts contrary to the existence or absence of facts or matters indicated.

This letter is furnished to you solely for the benefit of the Initial Purchasers pursuant to Section 6(a)(ii) of the Purchase Agreement. This letter and the opinions expressed and statements made herein may not be used or relied upon by the Initial Purchasers for any other purpose and may not be used or relied upon for any purpose by any other person or entity, without my prior written consent. Except for the use permitted herein, this letter is not to be quoted or reproduced in whole or in part or otherwise referred to in any manner nor is it to be filed with any governmental agency or delivered to any other person without my prior written consent. This letter speaks as of its date, and I undertake no (and hereby disclaim any) obligation to update this letter or the opinions expressed or the statements made herein.

Very truly yours,

C-3
