Execution Version

SEPARATION AGREEMENT AND GENERAL RELEASE OF CLAIMS

This SEPARATION AGREEMENT AND GENERAL RELEASE OF CLAIMS

(this “Agreement”) is entered into by and among Evan Kiefer (“Executive”) and Black Stone Natural Resources Management Company, a Delaware corporation (the “Company”). Black Stone Minerals GP, L.L.C., a Delaware limited liability company (the “General Partner”), joins this Agreement for the limited purpose of agreeing to Sections 2 and 13 below and those provisions of this Agreement necessary to interpret and apply them. The Company, the General Partner, and Executive are each referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, Executive was employed by the Company as Senior Vice President, Chief Financial Officer & Treasurer;

WHEREAS, Executive’s employment with the Company ended on May 28, 2024 (the “Separation Date”), and the Company and the General Partner wish to provide Executive with certain compensation and benefits as set forth herein, the receipt of which is dependent upon Executive’s timely entry into this Agreement and compliance with the terms of Articles III, IV and V of the Severance Agreement between Executive and the Company with an Effective Date of November 3, 2023 (the “Severance Agreement”); and

WHEREAS, for the purposes of avoiding the uncertainty, expense, and burden associated with any dispute, the Parties desire to settle any potential disputes, including those that may arise by virtue of either the employment relationship between Executive and the Company or the end of such employment relationship.

NOW, THEREFORE, in consideration of the promises and benefits set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged by the Parties, the Parties hereby agree as follows:

1. Separation from Employment. Executive’s employment with the Company ended as of the Separation Date. As of the Separation Date, Executive was no longer employed by the Company or any other Released Party (as defined below). As of the Separation Date, Executive is deemed to have automatically resigned (a) as an officer of the Company and each of its Affiliates (as defined in the Severance Agreement), as applicable, and (b) from the board of managers, board of directors, or similar governing body of each of the Company’s Affiliates (as applicable) and any other corporation, limited liability company, or other entity in which the Company or any of its Affiliates holds an equity interest or with respect to which board (or similar governing body) Executive serves or served as the designee or other representative of the Company or any of its Affiliates.

2. Separation Benefits. Provided that Executive (x) executes this Agreement on or after the Separation Date and on or before June 18, 2024, returns a copy of this Agreement that has been executed by him to the Company so that it is received by Steve Putman, Senior Vice President and General Counsel, 1001 Fannin Street, Suite 2020, Houston, Texas 77002 (email: sputman@blackstoneminerals.com) no later than 5:00 pm Houston, Texas time on June 18, 2024; and (y) remains in compliance with the other terms and conditions set forth in this Agreement, Executive shall receive the following consideration:

(a) The Company shall pay Executive $601,775.00 (the “Severance Payment”) in a single lump sum cash payment, which payment shall be made within sixty (60) days after the Separation Date.

(b) If Executive timely and properly elects to continue coverage for Executive and Executive’s spouse and eligible dependents, if any, under the Company’s group health plans pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) similar in the amounts and types of coverage provided by the Company to Executive prior to the Separation Date, then for a period of 12 months following the Separation Date, the Company shall promptly reimburse Executive on a monthly basis for the entire amount Executive pays to effect and continue such coverage; provided, however, that Executive’s rights to such reimbursements under this Section 2(b) shall terminate at the time Executive becomes eligible to be covered under a group health plan sponsored by another employer (and Executive shall immediately notify the Company in the event that Executive becomes so eligible) and such coverage becomes effective (so long as Executive elects such coverage upon his first opportunity to do so). Notwithstanding anything in the preceding provisions of this Section 2(b) to the contrary, the election of COBRA continuation coverage and the payment of any premiums due with respect to such COBRA continuation coverage will remain Executive’s sole responsibility, and the Company will assume no obligation for payment of any such premiums relating to such COBRA continuation coverage.

(c) Pursuant to the terms of Executive’s Restricted Unit Award Grant Notice and Restricted Unit Award Agreement dated February 2, 2022, Restricted Unit Award Grant Notice and Restricted Unit Award Agreement dated February 1, 2023 and Restricted Unit Award Grant Notice and Restricted Unit Award Agreement dated January 31, 2024 (collectively, the Restricted Unit Agreements”), the Forfeiture Restrictions (as defined in the Restricted Unit Agreements) on the Applicable Restricted Units (as defined in the Restricted Unit Agreements), which consist of 3,628 common units (“Common Units”) in Black Stone Minerals, L.P., a Delaware limited partnership (the “Partnership”), shall automatically lapse as of the date Executive executes this Agreement and the Applicable Restricted Units shall immediately thereafter become Earned Units (as defined in the Restricted Unit Agreements).

(d) Pursuant to the terms of Executive’s LTI Award Grant Notice and LTI Award Agreement dated February 2, 2022 (the “2022 Performance Unit Agreement”), (i) 3,052 Performance Units (as defined in the 2022 Performance Unit Agreement) shall become earned and will be settled in Common Units and (ii) in accordance with Section 4 of the 2022 Performance Unit Agreement, additional Common Units will be issued to Executive in settlement of the tandem DERs (as defined in the 2022 Performance Unit Agreement) relating to the Performance Units that have become earned, in each case, as soon as administratively practicable following Executive’s execution of this Agreement but in any event within 60 days following Executive’s execution of this Agreement.

(e) Pursuant to the terms of Executive’s LTI Award Grant Notice and LTI Award Agreement dated February 1, 2023 (the “2023 Performance Unit Agreement”), (i) 7,443 Performance Units (as defined in the 2023 Performance Unit Agreement) shall become earned and will be settled in Common Units and (ii) in accordance with Section 4 of the 2023 Performance Unit Agreement, additional Common Units will be issued to Executive in settlement of the tandem DERs (as defined in the 2023 Performance Unit Agreement) relating to the Performance Units that have become earned, in each case, as soon as administratively practicable following Executive’s execution of this Agreement but in any event within 60 days following Executive’s execution of this Agreement.

(f) Pursuant to the terms of Executive’s LTI Award Grant Notice and LTI Award Agreement dated January 31, 2024 (the “2024 Performance Unit Agreement”), (i) 1,684 Performance Units (as defined in the 2024 Performance Unit Agreement) shall become earned and will be settled in Common Units and (ii) in accordance with Section 4 of the 2024 Performance Unit Agreement, additional Common Units will be issued to Executive in settlement of the tandem DERs (as defined in the 2024 Performance Unit Agreement) relating to the Performance Units that have become earned, in each case, as soon as administratively practicable following Executive’s execution of this Agreement but in any event within 60 days following Executive’s execution of this Agreement.

(g) Pursuant to the terms of Executive’s LTI Award Grant Notice and LTI Award Agreement – Performance Units (Aspirational Program) dated February 18, 2022 (the “2022 Aspirational Performance Unit Agreement” and, together with the Restricted Unit Agreements, the 2022 Performance Unit Agreement, the 2023 Performance Unit Agreement, and the 2024 Performance Unit Agreement, the “LTI Award Agreements”), 50,893 Performance Units (as defined in the 2022 Aspirational Performance Unit Agreement) shall remain outstanding and will continue to be subject to the terms of the 2022 Aspirational Performance Unit Agreement and will become earned only if the Performance Goal is achieved for the Performance Period (each as defined in the 2022 Aspirational Performance Unit Agreement). The remainder of the Performance Units granted under the 2022 Aspirational Performance Agreement are hereby forfeited. Settlement of any units earned under the 2022 Aspirational Performance Unit Agreement will be made consistent with the terms of that agreement.

Executive acknowledges and agrees that the consideration described in this Section 2 represents the entirety of the amounts and other consideration Executive is eligible to receive as separation pay and benefits from the Company and any other Released Party and that Executive was not entitled to such pay or benefits but for his timely entry into this Agreement and compliance with the terms herein.

3. Post-Separation Consulting.

(a) During the Consulting Period (as defined below), Executive agrees to provide transition and consultation services to the General Partner and its Affiliates (the “Services”). In providing the Services, Executive shall act as an independent contractor to the General Partner and shall assist with the transition of his responsibilities and provide the General Partner with such assistance as the General Partner or CEO of the Company (the “CEO”) may deem necessary from time to time. Executive agrees to attend such meetings, if any, as the General Partner or CEO may reasonably require for communication of his advice and consultation. Executive shall work remotely and shall coordinate the furnishing of the Services with representatives of the General Partner or CEO in order that such services can be provided in such a way as to generally conform to the business schedules of the General Partner or its applicable Affiliate, but otherwise the method of performance, time of performance, place of performance, hours utilized in such performance, and other details of the manner of performance of Executive’s provision of the Services shall be within the sole control of Executive. Notwithstanding any provision of this Agreement, and unless reasonably requested by the General Partner or CEO, in no event shall Executive be obligated to make himself available to provide the Services for more than 20 hours in any single calendar week. During the Consulting Period, (i) Executive shall have the right to devote his business day and working efforts to other business and professional opportunities as do not interfere with his rendering of the Services to the General Partner or its Affiliates or his other obligations to the General Partner or any of the other Released Parties and (ii) Executive shall not be deemed to be an agent of the General Partner or any of its Affiliates or have any power to bind or commit the General Partner or any of its Affiliates or otherwise act on their behalf.

(b) In exchange for providing the Services, and for being available to do so, the General Partner shall pay Executive a consulting fee at the rate of $33,333.33 per complete calendar month during the Consulting Period, which amount shall be pro-rated for partial calendar months and paid to Executive within 30 days following the completion of each calendar month during the Consulting Period. Executive acknowledges and agrees that he is responsible for all federal, state and local taxes related to any compensation that he receives from the General Partner in connection with the consulting arrangements described herein (which includes all compensation described in this Section 3(b)).

(c) As of the Separation Date, Executive shall no longer be an employee of the Company or any other Released Party and nothing in this Agreement or elsewhere shall change that status. During the Consulting Period, Executive shall be an independent contractor and shall not participate in any pension or welfare benefit plans, programs or arrangements of the Company or any other Released Party unless such benefits are made available due to Executive’s former employment status with the Company.

(d) Unless earlier terminated as provided hereunder, the “Consulting Period” shall be that period between the Separation Date and November 30, 2024; provided, however, that the Consulting Period, and Executive’s and the General Partner’s respective obligations under this Section 3, shall be terminated prior to November 30, 2024 upon any of the following: (i) the death or disability of Executive; (ii) the termination of the Consulting Period by the General Partner for Consulting Period Cause; or (iii) the termination of the Consulting Period by mutual agreement of the Parties, as evidenced by a writing signed by Executive and the General Partner. For the avoidance of doubt, upon the termination of the Consulting Period, the General Partner shall have no further obligations to Executive pursuant to Section 3(b) above and the only payments owed to Executive by the General Partner following the termination of the Consulting Period shall be to provide payment for those Services performed prior to the date that the Consulting Period terminated. As used herein, “Consulting Period Cause” shall exist in the event that: (A) Executive breaches any of his obligations or covenants under this Agreement; or (B) during the Consulting Period, Executive engages in any act or omission that would give rise to Cause pursuant to clauses (b), (c), (d), or (e) of the definition of Cause in Section 1.4 of the Severance Agreement.

4. Release of Liability for Claims.

(a) For good and valuable consideration, including the consideration set forth in Section 2 (and any portion thereof), Executive hereby forever releases, discharges and acquits the Company, the Partnership, the General Partner, each of the foregoing entities’ respective Affiliates (as defined in the Severance Agreement), predecessors, successors, subsidiaries and benefit plans, and each of the foregoing entities’ respective equity-holders, officers, directors, managers, members, partners, employees, agents, representatives, and other affiliated persons, and the Company’s and its Affiliates’ benefit plans (and the fiduciaries and trustees of such plans) (each a “Released Party” and, collectively, the “Released Parties”), from liability for, and Executive hereby waives, any and all claims, damages, or causes of action of any kind related to Executive’s ownership of any interest in the Partnership or any other Released Party, his employment or engagement with any Released Party, the termination of such employment or engagement, and any other acts or omissions related to any matter occurring on or prior to the date that Executive executes this Agreement, including (i) any alleged violation through such time of:

(A) any federal, state or local anti-discrimination or anti-retaliation law, regulation or ordinance, including the Age Discrimination in Employment Act of 1967 (including as amended by the Older Workers Benefit Protection Act), Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, Sections 1981 through 1988 of Title 42 of the United States Code and the Americans with Disabilities Act of 1990, as amended; (B) the Employee Retirement Income Security Act of 1974 (“ERISA”); (C) the Immigration Reform Control Act; (D) the Sarbanes-Oxley Act of 2002 and the Dodd-Frank Wall Street Reform and Consumer Protection Act ; (E) the Occupational Safety and Health Act; (F) the Family and Medical Leave Act of 1993; (G) the Texas Labor Code (including the Texas Payday law, the Texas Anti-Retaliation Act, Chapter 21 of the Texas Labor Code and the Texas Whistleblower Act; (H) any federal, state or local wage and hour law; (I) any other local, state or federal law, regulation or ordinance; or (J) any public policy, contract, tort, or common law claim, including any claim for defamation, emotional distress, fraud or misrepresentation of any kind, promissory estoppel, breach of any implied duty of good faith and fair dealing, breach of implied or express contract, breach of fiduciary duty or wrongful discharge;

(ii) any allegation for costs, fees, or other expenses including attorneys’ fees incurred in or with respect to a Released Claim; (iii) any and all rights, benefits or claims Executive may have under any employment contract or other agreement (including the Severance Agreement), incentive compensation plan or equity-based plan with any Released Party (including the LTI Award Agreements) or to any ownership interest in any Released Party; (iv) any claim, whether direct or derivative, arising from, or relating to, Executive’s status as a holder of any shares or interests in any Released Party; and (v) any claim for compensation or benefits of any kind not expressly set forth in this Agreement (collectively, the “Released Claims”). This Agreement is not intended to indicate that any such claims exist or that, if they do exist, they are meritorious. Rather, Executive is simply agreeing that, in exchange for any consideration received by Executive pursuant to Section 2, any and all potential claims of this nature that Executive may have against the Released Parties, regardless of whether they actually exist, are expressly settled, compromised and waived. THIS RELEASE INCLUDES MATTERS ATTRIBUTABLE TO THE SOLE OR PARTIAL NEGLIGENCE (WHETHER GROSS OR SIMPLE) OR OTHER FAULT, INCLUDING STRICT LIABILITY, OF ANY OF THE RELEASED PARTIES.

For the avoidance of doubt, nothing in this Agreement releases Executive’s rights to receive payments or benefits pursuant to Section 2 of this Agreement (including Executive’s right to the Severance Payment and the rights set forth in Section 2 with respect to the Restricted Unit Agreements, 2022 Performance Unit Agreement, 2023 Performance Unit Agreement, 2024 Performance Unit Agreement and, pending the future determination of whether any amounts are payable, the 2022 Aspirational Performance Unit Agreement). Further, in no event shall the Released Claims include (i) any claim that arises after the date that Executive signs this Agreement; (ii) any claim to vested benefits under an employee benefit plan that is subject to ERISA and that cannot be released pursuant to ERISA; or (iii) any claim for breach of this Agreement. Further notwithstanding this release of liability, nothing in this Agreement prevents Executive from filing any non-legally waivable claim (including a challenge to the validity of this Agreement) with the Equal Employment Opportunity Commission (“EEOC”) or comparable state or local agency or participating in (or cooperating with) any investigation or proceeding conducted by the EEOC or comparable state or local agency or cooperating in any such investigation or proceeding; however, Executive understands and agrees that Executive is waiving any and all rights to

recover any monetary or personal relief from a Released Party as a result of such EEOC or comparable state or local agency or proceeding or subsequent legal actions. Further, nothing in this Agreement or the Severance Agreement prohibits or restricts Executive from filing a charge or complaint with, or cooperating in any investigation with, or making disclosures to, the Securities and Exchange Commission, the Financial Industry Regulatory Authority, or any other securities regulatory agency or authority (each, a “Government Agency”), and nothing herein will require Executive to inform any Released Party that he has made such a charge, complaint or disclosure or that he is engaging in such cooperation. This Release does not limit Executive’s right to receive an award for information provided to a Government Agency. Further, this Release does not release Executive’s right to seek unemployment insurance or workers’ compensation benefits.

5. Representations and Warranties Regarding Claims. Executive represents and warrants that, as of the time at which he signs this Agreement, he has not made any assignment, sale, delivery, transfer or conveyance of any rights Executive has asserted or may have against any of the Released Parties with respect to any Released Claim.

6. Affirmation of Restrictive Covenants; Prohibited Period.

Executive acknowledges and agrees that in connection with Executive’s employment with the Company, Executive has obtained Confidential Information (as defined in the Severance Agreement) and that Executive has continuing obligations to the Company and each of its Affiliates pursuant to pursuant to Articles III, IV and V of the Severance Agreement. In entering into this Agreement, Executive acknowledges the validity, binding effect and enforceability of Articles III, IV and V of the Severance Agreement and expressly reaffirms Executive’s commitment to abide by such provisions of the Severance Agreement and promises to do so. For the avoidance of doubt, Executive’s promises include Executive’s commitment not to use or disclose non-public information regarding the Company or any of its Affiliates for the benefit of any other business, and Executive promises that Executive will not do so, including any manner that results in any individual or entity buying, selling, or otherwise transacting with respect to any equity or other security in the Company or any of its Affiliates as a result of any violation of Executive’s non-disclosure obligations.

Notwithstanding the foregoing, nothing herein or in the Severance Agreement will prohibit or restrict Executive from lawfully: (i) initiating communications directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by, any governmental authority regarding a possible violation of any law; (ii) responding to any inquiry or legal process directed to Executive from any such governmental authority; (iii) testifying, participating or otherwise assisting in any action or proceeding by any such governmental authority relating to a possible violation of law; or (iv) making any other disclosures that are protected under the whistleblower provisions of any applicable law. Additionally, pursuant to the federal Defend Trade Secrets Act of 2016, an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (A) is made (1) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and (2) solely for the purpose of reporting or investigating a suspected violation of law; (B) is made to the individual’s attorney in relation to a lawsuit for retaliation against the individual for reporting a suspected violation of law; or (C) is made in a complaint or other document filed in a lawsuit or proceeding, if such filing is made under seal.

7. Covenant to Cooperate in Legal Proceedings. Executive agrees to cooperate in good faith with and provide reasonable assistance to the Company and its Affiliates, upon the Company’s reasonable request, with respect to the defense or prosecution of any litigation, investigation or other legal proceeding involving the Company or any of its Affiliates.

8. Advice to Consult with Counsel; Executive’s Acknowledgments. This is an important legal document, and Executive is advised to consult with a lawyer of his choosing before entering into this Agreement. By executing and delivering this Agreement, Executive expressly acknowledges that:

(a) Executive has carefully read this Agreement;

(b) Executive has been given at least 21 days to review and consider this Agreement. If Executive signs this Agreement before the expiration of 21 days after Executive’s receipt of this Agreement, Executive has knowingly and voluntarily waived any longer consideration period than the one provided to Employee. No changes (whether material or immaterial) to this Agreement shall restart the running of this 21-day period.

(c) Executive is receiving, pursuant to this Agreement, consideration in addition to anything of value to which he is already entitled;

(d) Executive has been advised, and hereby is advised in writing, to discuss this Agreement with an attorney of Executive’s choice before signing this Agreement, and Executive represents that has had an adequate opportunity to do so prior to executing this Agreement;

(f) The only matters relied upon by Executive and causing Executive to sign this Agreement are the provisions set forth in writing within the four corners of this Agreement;

(g) No Released Party has provided any tax or legal advice regarding this Agreement and he has had an adequate opportunity to receive sufficient tax and legal advice from advisors of his own choosing such that he enters into this Agreement with full understanding of the tax and legal implications thereof;

(h) Executive has complied with all reporting requirements under Sections 13 and 16 of the Securities Exchange Act of 1934 with respect to transactions in Company securities made on or before the Separation Date and agrees to provide the General Partner with any information required in the future to comply with its reporting obligations; and

(i) Executive acknowledges that he may still be in possession of material nonpublic information and remains subject to all applicable laws relating to insider trading.

9. Governing Law. This Agreement is entered into under, and shall be governed for all purposes by, the laws of the State of Texas (other than Sections 2(c), 2(d), 2(e), 2(f) and 2(g), which shall be construed under and governed for all purposes by the laws of the State of Delaware) without regard to the principles of conflicts of law thereof.

10. Counterparts. This Agreement may be executed in one or more counterparts (including portable document format (.pdf) and facsimile counterparts), each of which shall be deemed to be an original, but all of which together will constitute one and the same Agreement.

11. Amendment; Entire Agreement. This Agreement may not be changed orally but only by an agreement in writing agreed to and signed by the Party to be charged. This Agreement, with respect to the covenants referenced in Section 6, the Severance Agreement, and with respect to Sections 2(c), 2(d), 2(e), 2(f) and 2(g), the LTI Award Agreements, constitute the entire agreement of the Parties with regard to the subject matter hereof and supersede all prior and contemporaneous agreements and understandings, oral or written, between Executive and any Released Party with regard to the subject matter hereof.

12. Dispute Resolution. Any dispute, controversy or claim between Executive, on the one hand, and the Company, the General Partner or any of their Affiliates (as defined in the Severance Agreement), on the other hand, arising out of or relating to this Agreement shall be subject to the dispute resolution provisions set forth in Article VI of the Severance Agreement, which provisions are hereby incorporated by reference. IN ENTERING INTO THIS AGREEMENT, THE PARTIES EXPRESSLY ACKNOWLEDGE AND AGREE THAT THEY ARE KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVING THEIR RIGHTS TO JURY TRIAL.

13. Third-Party Beneficiaries. Executive expressly acknowledges and agrees that each Released Party that is not a party to this Agreement shall be a third-party beneficiary of Sections 3, 4, 6, 7 and 15 (to the extent such Sections reference such Released Party), and entitled to enforce such provisions as if it were a party hereto.

14. Further Assurances. Executive shall, and shall cause his Affiliates, representatives and agents to, from time to time at the request of the Company and without any additional consideration, furnish the Company with such further information or assurances, execute and deliver such additional documents, instruments and conveyances, and take such other actions and do such other things, as may be reasonably necessary or desirable, as determined in the sole discretion of the Company, to carry out the provisions of this Agreement.

15. Return of Property. Executive agrees that, except as previously approved by the Company or otherwise stated herein, upon execution of this Agreement, he will return to the Company all property belonging to the Company or any other Released Party, including all computer files, electronically stored information, computers and other materials and items provided to him by the Company or any other Released Party in the course of his employment and Executive further represents and warrants that he will not maintain a copy of any such materials or items in any form. The Parties expressly agree that Executive may keep his Company-issued cellular phone, laptop, and associated peripherals.

16. Non-Defamation. Executive agrees that Executive will not defame, slander, or libel the Company or any other Released Party in any manner at any time in the future. The Company agrees that Thomas L. Carter, Carrie Clark, Steve Putman, and Kristin Wiggs will be instructed not to defame, slander or libel Executive.

17. Severability. Any term or provision of this Agreement (or part thereof) that renders such term or provision (or part thereof) or any other term or provision (or part thereof) hereof invalid or unenforceable in any respect shall be severable and shall be modified or severed to the extent necessary to avoid rendering such term or provision (or part thereof) invalid or unenforceable, and such modification or severance shall be accomplished in the manner that most nearly preserves the benefit of the Parties’ bargain hereunder.

18. Headings; References; Interpretation. The Section headings have been inserted for purposes of convenience and shall not be used for interpretive purposes. The words “hereof,” “herein” and “hereunder” and other compounds of the word “here” shall refer to the entire Agreement and not to any particular provision hereof. The use herein of the word “including” following any general statement, term or matter shall not be construed to limit such statement, term or matter to the specific items or matters set forth immediately following such word or to similar items or matters, whether or not non-limiting language (such as “without limitation”, “but not limited to”, or words of similar import) is used with reference thereto, but rather shall be deemed to refer to all other items or matters that could reasonably fall within the broadest possible scope of such general statement, term or matter. The word “or” as used herein is not exclusive and is deemed to have the meaning “and/or.” Unless the context requires otherwise, all references herein to a law, agreement, instrument or other document shall be deemed to refer to such law, agreement, instrument or other document as amended, supplemented, modified and restated from time to time to the extent permitted by the provisions thereof. Neither this Agreement nor any uncertainty or ambiguity herein shall be construed against any Party, whether under any rule of construction or otherwise. This Agreement has been reviewed by each of the Parties and shall be construed and interpreted according to the ordinary meaning of the words used so as to fairly accomplish the purposes and intentions of the Parties.

19. Withholdings; Deductions. The Company may withhold and deduct from any benefits and payments and issuances of Common Units made or to be made pursuant to this Agreement (a) all federal, state, local and other taxes as may be required pursuant to any law or governmental regulation or ruling and (b) any deductions consented to in writing by Executive, including in accordance with the terms of the LTI Award Agreements.

20. Section 409A.

(a) This Agreement and the benefits provided hereunder are intended be exempt from, or compliant with, the requirements of Section 409A of the Internal Revenue Code of 1986 and the Treasury regulations and other guidance issued thereunder (collectively, “Section 409A”) and shall be construed and administered in accordance with such intent. Each installment payment under this Agreement shall be deemed and treated as a separate payment for purposes of Section 409A. Notwithstanding the foregoing, the Company makes no representations that the benefits provided under this Agreement are exempt from the requirements of Section 409A and in no event shall the Company or any of its Affiliates be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by Executive on account of non- compliance with Section 409A.

(b) To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A), (i) any such expense reimbursement shall be made by the Company no later than the last day of Employee’s taxable year following the taxable year in which such expense was incurred by Employee, (ii) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period in which the arrangement is in effect.
