This Phantom Unit Award Agreement (this “Agreement”) is made and entered into as of [●] (the “Date of Grant”) by and between GP Natural Resource Partners LLC, a Delaware limited liability company (“GP LLC”), and [●] (“you” or “Service Provider”). Capitalized terms used but not specifically defined herein shall have the meanings specified in the Natural Resource Partners L.P. 2017 Long Term Incentive Plan (the “Plan”).

WHEREAS, Natural Resource Partners L.P., a Delaware limited partnership (the “Partnership”), acting through the Board of Directors of GP LLC (the “Board”), the general partner of NRP (GP) LP, a Delaware limited partnership, the general partner of the Partnership (the “General Partner”), GP LLC has adopted the Plan under which GP LLC is authorized to grant Phantom Units to certain Service Providers of the Partnership;

    WHEREAS, the Partnership, in order to induce you to enter into and to continue to dedicate service to the Partnership and to materially contribute to the success of the Partnership, agrees to grant you the Phantom Unit Award;

    WHEREAS, a copy of the Plan has been furnished to you and shall be deemed a part of this Agreement as if fully set forth herein; and

    WHEREAS, you desire to accept the Phantom Unit Award made pursuant to this Agreement.

NOW, THEREFORE, in consideration of and mutual covenants set forth herein and for other valuable consideration hereinafter set forth, the parties agree as follows:

1.The Grant. Subject to the conditions set forth below, the Partnership hereby grants you effective as of the Date of Grant, as a matter of separate inducement but not in lieu of any salary or other compensation for your services to the Partnership, an Award consisting of [●] Phantom Units (the “Phantom Unit Award”) in accordance with the terms and conditions set forth in this Agreement and the Plan, whereby each Phantom Unit represents the right to receive one Unit on the date the Forfeiture Restrictions expire with respect to such Phantom Unit.

2.Phantom Unit Account. The Partnership shall establish and maintain a bookkeeping account on its records for you (a “Phantom Unit Account”) and shall record in such Phantom Unit Account: (a) the number of Phantom Units granted to you, (b) the amount deliverable to you at settlement on account of Phantom Units that have vested and (c) the amount of any distribution equivalent rights credited to you in accordance with Section 5 hereof. You shall not have any interest in any fund or specific assets of the Partnership by reason of this Award or the Phantom Unit Account established for you.

3.Rights of Service Provider. No Units shall be issued to you at the time the grant is made, and you shall not be, nor have any of the rights and privileges of, a unitholder or limited partner of the Partnership with respect to any Phantom Units recorded in the Phantom Unit Account. You shall have no voting rights with respect to the Phantom Units.

4.Vesting of Phantom Units. The Phantom Units are restricted in that they may be forfeited by the Service Provider and in that they may not, except as otherwise provided in the Plan, be transferred or otherwise disposed of by the Service Provider. Subject to the terms and conditions of this Agreement, the restrictions with respect to the Phantom Unit Award (including any associated DERs) will expire and such Phantom Units will become vested and nonforfeitable as set forth on Schedule I hereto; provided, however, that the restrictions will expire on such date(s) only if your service relationship with GP LLC, the General Partner, the Partnership, or any of the Partnership’s subsidiaries (collectively, the “Partnership Group”) continues from the Date of Grant through the applicable vesting date.

5.Distribution Equivalent Rights. The Partnership hereby grants to you rights to dividend equivalents with respect to the Phantom Units granted pursuant to this Agreement (“DERs”). The DERs awarded to you under this Section 5 shall entitle you to the payment, with respect to each Unit that is subject to a Phantom Unit granted pursuant to this Agreement that has not been cancelled or forfeited, of an amount in cash equal to the amount of any cash dividend or Unit distribution paid by the GP LLC with respect to one Unit while such Phantom Unit remains outstanding. Such amount shall be subject to the same vesting schedule as the Phantom Unit to which it relates and shall be paid to you in cash on the date that the Phantom Unit to which it relates is settled in accordance with Section 8 hereof. No interest shall be payable or otherwise owed with respect to such DERs for the period of time beginning on the date a distribution is paid to the Partnership’s unitholders and ending on the date the DERs are paid to you pursuant to this Agreement. Any DERs which relate to a Phantom Unit that do not become vested shall be forfeited at the same time the related Phantom Unit is forfeited.

6.Terminations of Services. Except as otherwise provided in Sections 6(a), (b), (c), and (d) below, if your service relationship with the Partnership Group is terminated for any reason, then the portion of the Phantom Unit Award (and any associated DERs) for which the Forfeiture Restrictions have not lapsed as of the date of termination shall become null and void and such Phantom Units shall be forfeited. The portion of the Phantom Unit Award for which the Forfeiture Restrictions have lapsed as of the date of such termination shall not be forfeited.

a.    Death or Disability. If your service relationship with the Partnership Group is terminated due to your death or Disability, then the Forfeiture Restrictions on the Phantom Unit Award shall immediately lapse, and the Phantom Unit Award will be fully vested as of such termination. For purposes of this Phantom Unit Award, “Disability” shall have the meaning given such term in any employment agreement between you and the Partnership or its Affiliates. Provided, however, that if there is no existing employment agreement between you and the Partnership or its Affiliates, the term “Disability” shall mean that you are unable to engage in substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or can be expected to last for a continuous period of not less than 12 months.

b.    Change of Control. In the event of a Change of Control, the Forfeiture Restrictions on the Phantom Unit Award shall immediately lapse, and the Phantom Unit Award will be fully vested as of the date of such Change of Control.

c.    Termination of Service Provider Without Cause. If your service relationship with the Partnership Group is terminated by the Partnership or any of its Affiliates for any reason other than for Cause, then the Forfeiture Restrictions on the Phantom Unit Award shall immediately lapse, and the Phantom Unit Award will be fully vested as of such termination. “Cause” means one or more of the following events: (i) a Service Provider’s continued failure, after written notice is given and a reasonable opportunity to cure has been granted, to comply with the reasonable written directives of the Partnership or any of its Affiliates, (ii) a Service Provider’s failure to comply in any material respect with the written terms of employment with the Partnership or any of its Affiliates, (iii) a Service Provider’s willful misconduct resulting in material and demonstrable damage to the Partnership or any of its Affiliates, including, without limitation, theft, embezzlement or material misrepresentations or concealments on any written reports submitted to such the Partnership or any of its Affiliates, (iv) Service Provider’s conviction of, or plea of nolo contendere to, any felony or to any crime or offense involving acts of theft, fraud, embezzlement or similar conduct or (v) Service Provider’s material breach of written policies of the Partnership or any of its Affiliates concerning employee discrimination or harassment, after written notice is given and a reasonable opportunity to cure been granted, if such breach is capable of being cured without penalty or damages to the Partnership or any of its Affiliates.

d.    Termination by Service Provider for Good Reason. If your service relationship with the Partnership Group is terminated due to Good Reason, then the Forfeiture Restrictions on the Phantom Unit Award shall immediately lapse, and the Phantom Unit Award will be fully vested as of such termination. “Good Reason” means the occurrence, without the Service Provider’s express written consent of (i) a reduction in Service Provider’s then current annual base salary of 10% or more; or (ii) a material diminution in Service Provider’s authority, duties or responsibilities (other than a mere change in the person or persons to whom Service Provider reports); provided, however, that Service Provider must give written notice to the Partnership Group of the existence of such a condition described in (i) or (ii) above within ninety (90) days of the initial existence of the condition, and the Partnership Group shall have thirty (30) days from the date when such notice is provided to cure the condition (if such condition can be cured) without being required to accelerate vesting for unvested awards due to termination of employment. To the extent that notice is provided in accordance with the foregoing sentence and the condition is not cured within the 30-day period, then Service Provider must actually terminate such Service Provider’s relationship with the Partnership Group within six (6) months of the initial occurrence of any of the conditions above for such termination to qualify as Good Reason.

7.Leave of Absence. With respect to the Phantom Unit Award, the Partnership may, in its sole discretion, determine that if you are on a leave of absence for any reason, you will be considered to still be a Service Provider to the Partnership Group; provided, that rights to the Phantom Unit Award during a leave of absence will be limited to the extent to which those rights were earned or vested when the leave of absence began.

8.Settlement Date; Manner of Settlement. Promptly following the expiration of the Forfeiture Restrictions and upon receipt by the Partnership of any tax withholding as may be required pursuant to Section 9, but in no event later than the first March 15 following the date the Forfeiture Restrictions expire with respect to a Phantom Unit, the Partnership shall deliver to you the number

of Units equal to the number of Phantom Units granted to you hereunder as to which the Forfeiture Restrictions have lapsed. In addition, the Partnership shall deliver to you an amount of cash equal to the DERs that relate to the Phantom Units as to which the Forfeiture Restrictions have lapsed. The amounts deliverable pursuant to this Section 8 shall not bear any interest owing to the passage of time.

9.Payment of Taxes. The Partnership may require you to pay to the Partnership (or a Partnership Affiliate if you are a Service Provider to a Partnership Affiliate) an amount the Partnership deems necessary to satisfy its (or its Affiliate’s) current or future obligation to withhold federal, state or local income or other taxes that you incur as a result of the Phantom Unit Award. With respect to any required tax withholding, the Partnership (or its Affiliate) may withhold from the amount deliverable to you under this Agreement the amount necessary or appropriate to satisfy the Partnership’s (or its Affiliate’s) obligation to withhold taxes.

10.Clawback. Notwithstanding any provisions in the Plan or this Agreement to the contrary, any portion of the payments and benefits provided under this Agreement shall be subject to any clawback policy adopted by GP LLC, including any such policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and rules promulgated thereunder by the Securities and Exchange Commission, and including any such clawback policies adopted with retroactive effect.

Service Provider acknowledges and agrees that (a) Service Provider is not relying upon any determination by GP LLC, the General Partner, the Partnership, any of their respective Affiliates, or any of their respective employees, directors, officers, attorneys, or agents (collectively, the “Partnership Parties”) of the Fair Market Value of the Units on the Date of Grant, (b) Service Provider is not relying upon any written or oral statement or representation of the Partnership Parties regarding the tax effects associated with your execution of the Agreement and his or her receipt, holding and vesting of the Phantom Unit Award, and (c) in deciding to enter into this Agreement, Service Provider is relying on his or her own judgment and the judgment of the professionals of Service Provider’s choice with whom he or she has consulted. Service Provider hereby releases, acquits and forever discharges the Partnership Parties from all actions, causes of actions, suits, debts, obligations, liabilities, claims, damages, losses, costs and expenses of any nature whatsoever, known or unknown, on account of, arising out of, or in any way related to the tax effects associated with Service Provider’s execution of the Agreement and his or her receipt, holding and exercise of the Phantom Unit Award.
