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, 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 and Transferability. 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 on the one year anniversary of the Date of Grant; provided, however, that the restrictions will expire on such date only if you remain a member of the Board continuously from the Date of Grant through the 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, 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.

6.Termination of Board Service. If your service as a member of the Board terminates 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.

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, 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.Right of the Partnership and its Affiliates to Terminate Services. Nothing in this Agreement confers upon you the right to continue as a Service Provider for the Partnership or its Affiliates, or interfere in any way with the rights of the Partnership or its Affiliates to terminate your service relationship at any time.
