THE PARTICIPANT ACKNOWLEDGES THAT THE PARTICIPANT HAS BEEN INFORMED OF THE AVAILABILITY OF MAKING AN ELECTION IN ACCORDANCE WITH SECTION 83(b) OF THE CODE; THAT SUCH ELECTION MUST BE FILED WITH THE INTERNAL REVENUE SERVICE (AND A COPY OF THE ELECTION GIVEN TO THE PARTNERSHIP) WITHIN 30 DAYS OF THE GRANT DATE; AND THAT THE PARTICIPANT IS SOLELY RESPONSIBLE FOR MAKING SUCH ELECTION.

Reasonably promptly and in all events, no more than three (3) business days following the Grant Date, the Company shall cause this Award to be entered as book entry Restricted Units in the Partnership’s ledger, which ledger shall bear the following (or a similar) legend in addition to any other legends that may be required under federal or state securities laws:

“THE TRANSFERABILITY OF THE UNITS REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS (INCLUDING FORFEITURE) CONTAINED IN THE PEAK RESOURCES LP 2024 LONG-TERM INCENTIVE PLAN AND THE RESTRICTED UNIT AWARD AGREEMENT DATED AS OF [DATE], 2024 ENTERED INTO BY AND AMONG THE REGISTERED OWNER, PEAK RESOURCES GP LLC AND PEAK RESOURCES LP.

The Participant agrees that, to ensure compliance with the restrictions imposed by this Agreement, the Company may, only until such Restricted Units vest, issue appropriate “stop-transfer” instructions to its transfer agent, if any, and if the Company of the Partnership transfers the Partnership’s securities, it may make appropriate notations to the same effect in its own records. The Company will not be required to (i) register any transfer of Restricted Units on the Partnership’s list of Limited Partners if such Restricted Units have been sold or otherwise transferred in violation of any of the provisions of this Agreement or (ii) treat as the owner of such Restricted Units, or to accord the right to vote or make distributions to any purchaser or other transferee to whom such Restricted Units have been so transferred. Upon or as soon as reasonably practicable following the vesting of the Restricted Units, subject to the Participant satisfying the tax withholding obligation under Section 4(a), the Participant shall be entitled to have the restrictions removed from the Participant’s book-entry account so that the Participant holds an unrestricted Unit. Notwithstanding the foregoing, such unrestricted Units shall be subject to such stop transfer orders and other restrictions as the Company may deem advisable under the Plan or the rules, regulations, and other requirements of the SEC, any stock exchange upon which such Units are then listed, and any applicable federal or state laws, and the Company may cause a legend or legends to be inscribed on any such book entry to make appropriate reference to such restrictions. In addition to the terms and conditions provided herein, the Company may require that the Participant make such covenants, agreements, and representations as the Company, in its sole discretion, deems advisable in order to comply with any such laws, regulations, or requirements.

6. Partnership Agreement. The Units issued hereunder shall be subject to the terms of the Plan and the Partnership Agreement. Upon the Grant Date, the Participant shall, automatically and without further action on the Participant’s part, (i) be admitted to the Partnership as a Limited Partner (as defined in the Partnership Agreement) with respect to the Units, and (ii) become bound, and be deemed to have agreed to be bound, by the terms of the Partnership Agreement.

7. No Effect on Service; No Right to Continued Awards. Nothing in this Agreement or in the Plan shall be construed as giving the Participant the right to be retained in the employ or service of the Company or any Affiliate thereof. Furthermore, the Company and its Affiliates may at any time dismiss the Participant from employment, service or consulting free from any liability or any claim under the Plan or this Agreement, unless otherwise expressly provided in the Plan, this Agreement or any other written agreement between the Participant and the Company or an Affiliate thereof. The grant of the Restricted Units is a one-time Award and does not create any contractual or other right to receive a grant of Awards or benefits in lieu of Awards in the future. Future Awards will be at the sole discretion of the Committee.

8. Severability. If any provision of this Agreement is or becomes or is deemed to be invalid, illegal, or unenforceable in any jurisdiction, such provision shall be construed or deemed amended to conform to the applicable law or, if it cannot be construed or deemed amended without, in the determination of the Committee, materially altering the intent of this Agreement, such provision shall be stricken as to such jurisdiction, and the remainder of this Agreement shall remain in full force and effect.

9. Entire Agreement; Amendments, Suspension and Termination. This Agreement, the Plan, and the Partnership Agreement constitute the entire agreements of the parties with regard to the subject matter hereof, and contain all the covenants, promises, representations, warranties and agreements between the parties with respect to the Restricted Units granted hereunder. To the extent expressly permitted by the Plan, this Agreement may be wholly or partially amended or otherwise modified, suspended or terminated at any time or from time to time by the Board or the Committee. Except as provided in the preceding sentence, this Agreement cannot be modified, altered or amended, except by an agreement, in writing, signed by both the Partnership and the Participant.

10. Lock-Up Agreement. The Participant shall agree, if so requested by the Company or the Partnership and any underwriter in connection with any public offering of securities of the Partnership or any Affiliate thereof, not to directly or indirectly offer, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant for the sale of or otherwise dispose of or transfer any Units held by the Participant for such period, not to exceed one hundred eighty (180) days following the effective date of the relevant registration statement filed under the Securities Act in connection with such public offering, as such underwriter shall specify reasonably and in good faith. The Company or the Partnership may impose stop-transfer instructions with respect to securities subject to the foregoing restrictions until the end of such 180-day period. Notwithstanding the foregoing, the 180-day period may be extended in the discretion of the Company for up to such number of additional days as is deemed necessary by such underwriter or the Company or Partnership to continue coverage by research analysts in accordance with FINRA Rule 2711 or any successor or other applicable rule.

11. Conformity to Securities Laws. The Participant acknowledges that the Plan and this Agreement are intended to conform to the extent necessary with all provisions of the Securities Act and the Exchange Act, any and all regulations and rules promulgated by the SEC thereunder, and all applicable state securities laws and regulations. Notwithstanding anything herein to the contrary, the Plan shall be administered, and the Restricted Units are granted, only in such a manner as to conform to such laws, rules and regulations. To the extent required by applicable law, the Plan and this Agreement shall be deemed amended to the extent necessary to conform to such laws, rules and regulations. The inability to obtain from any regulatory body having jurisdiction the authority, if any, deemed by the Company’s or the Partnership’s legal counsel to be necessary for the lawful issuance and sale of any Units hereunder will relieve the Company, the Partnership and any of their respective Affiliates of any liability in respect of the failure to issue such Units as to which such requisite authority has not been obtained.

12. Adjustments; Clawback. The Participant acknowledges that the Restricted Units are subject to modification and forfeiture in certain events as provided in this Agreement and Section 7 of the Plan. The Participant further acknowledges that the Restricted Units, whether vested or unvested and whether or not previously issued, are subject to clawback as provided in Section 8(o) of the Plan.

The Company or the Partnership may assign any of its rights under this Agreement to single or multiple assignees, and this Agreement shall be binding upon and inure to the benefit of the successors and assigns of the Company and the Partnership. Subject to the restrictions on transfer contained herein, this Agreement shall be binding upon and inure to the benefit of the Participant and the Participant’s heirs, executors, administrators, successors and assigns.

14. Governing Law. The validity, construction, and effect of this Agreement and any rules and regulations relating to this Agreement shall be determined in accordance with the laws of the State of Delaware without regard to its conflicts of laws principles.

15. Headings. Headings are given to the sections and subsections of this Agreement solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of this Agreement or any provision hereof.
