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 Brock Morris (“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, 3 and 13 below. 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, Engineering and Geology;

WHEREAS, Executive’s employment with the Company ended as of February 24, 2020 (the “Separation Date”), and the Company and the General Partner wish to provide Executive with certain compensation and benefits, the receipt of which is dependent upon Executive’s timely entry into (and non-revocation in the time provided to do so of) this Agreement and compliance with the terms of Articles III, IV and V of the Severance Agreement between Executive and the Company dated May 6, 2015 (the “Severance Agreement”), as such Severance Agreement may be amended pursuant to Section 2(f) and Section 2(g); 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 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 prior to April 9, 2020, 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: ***@***) no later than 5:00 pm Houston, Texas time on April 9, 2020; (y) does not revoke his acceptance of this Agreement pursuant to Section 9; and (z) 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 $709,590.16 (the “Severance Payment”) in a single lump sum cash payment after the date that is 60 days after the Separation Date, but in no event later than the date that is 70 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 20, 2018 and Restricted Unit Award Grant Notice and Restricted Unit Award Agreement dated February 7, 2019 (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 2,733 common units (“Common Units”) in Black Stone Minerals, L.P., a Delaware limited partnership (the “Partnership”), shall automatically lapse as of the last day of the Release Revocation Period (as defined below) (such last day, the “Release Revocation Expiration Date”) 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 20, 2018 (the “2018 Performance Unit Agreement”), (i) 37,972 Performance Units (as defined in the 2018 Performance Unit Agreement) shall become earned and will be settled in Common Units and (ii) in accordance with Section 4 of the 2018 Performance Unit Agreement, additional Common Units will be issued to Executive in settlement of the tandem DERs (as defined in the 2018 Performance Unit Agreement) relating to the Performance Units that have become earned, in each case, as soon as administratively practicable following the Release Revocation Expiration Date but in any event within 60 days following the Release Revocation Expiration Date.

2

(e) Pursuant to the terms of Executive’s LTI Award Grant Notice and LTI Award Agreement dated February 7, 2019 (the “2019 Performance Unit Agreement” and together with the Restricted Unit Agreements and the 2018 Performance Unit Agreement, the “LTI Award Agreements”), (i) 19,369 Performance Units (as defined in the 2019 Performance Unit Agreement) shall become earned and will be settled in Common Units and (ii) in accordance with Section 4 of the 2019 Performance Unit Agreement, additional Common Units will be issued to Executive in settlement of the tandem DERs (as defined in the 2019 Performance Unit Agreement) relating to the Performance Units that have become earned, in each case, as soon as administratively practicable following the Release Revocation Expiration Date but in any event within 60 days following the Release Revocation Expiration Date.

(f) Effective as of the Release Revocation Expiration Date, the definition of “Restricted Area” within the Severance Agreement shall be deemed modified so that, as of such date, the term “Restricted Area” within the Severance Agreement shall be interpreted and applied with respect to Executive to mean only that geographic area within the red and blue dashed line boundaries labeled “Available Development Areas” and “XTO Development Area” on the map attached hereto as Exhibit A. For the avoidance of doubt, if Executive fails to comply with the terms herein, including Section 3 below, this Section 2(f) shall be of no force or effect and the “Restricted Area” as defined in the Severance Agreement shall again have the meaning as in effect as of the Separation Date.

(g) Executive may prepare and, beginning on the Separation Date, share with third parties a summary “track record” reflecting the performance of acquisitions made during the term of Executive’s employment by the Company, substantially in the form of Exhibit C to this Agreement (the “Form Track Record”) or otherwise consistent with the conditions in this Section 2(g). The track record (including the Form Track Record):

(i) will not contain Company data (or be based on Company data) beyond that used to prepare the Form Track Record;

(ii) will not contain any material nonpublic information relating to the Company;

(iii) will be labeled to make clear that (A) it was prepared by the Executive and not the Company (B) the Company does not make any representation as to the accuracy of the information presented.

Executive acknowledges and agrees that the consideration described in this Section 2 represents the entirety of the amounts 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 (and non-revocation of his acceptance of) this Agreement and compliance with the terms herein.

3. Post-Separation Consulting. Following the Separation Date, upon request from the Company or the General Partner, Executive agrees to cooperate with and assist the Company, the General Partner and their respective designees in order to provide such information and assistance as the Company or the General Partner may reasonably request from time to time, which cooperation and assistance may include providing consultation and advice with respect to the duties that Executive had performed for the Company and the General Partner and the transition of such duties. The Company agrees that it will promptly reimburse Executive for all pre-approved expenses incurred in connection with such post-separation consulting.

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 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) (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 with any Released Party, the termination of such employment, 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 National Labor Relations 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; (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 (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; and (iv) 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.

(b) 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, 2018 Performance Unit Agreement and 2019 Performance Unit Agreement). Further, in no event shall the Released Claims include (i) any claim that arises after

4

the date that Executive signs this Agreement; (ii) any claim to vested benefits under an employee benefit plan that is subject to ERISA; (iii) any claim relating to the settlement of the performance units granted under Executive’s LTI Award Grant Notice and LTI Award Agreement dated February 15, 2017; (iv) any claim for the payment of Executive’s short-term incentive award for the 2019 calendar year; or (v) any claim for breach of, or otherwise arising out 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 Release or the Separation Agreement prohibits or restricts Executive from filing a charge or complaint with, or cooperating in any investigation with, the Securities and Exchange Commission, the Financial Industry Regulatory Authority, or any other securities regulatory agency or authority (each, a “Government Agency”). This Release does not limit Executive’s right to receive an award for information provided to a Government Agency.

5. Representations and Warranties Regarding Claims. Executive represents and warrants that, as of the time at which he signs this Agreement, he has not filed or joined any claims, complaints, charges, or lawsuits against any of the Released Parties with any governmental agency or with any state or federal court or arbitrator for, or with respect to, a matter, claim, or incident that occurred or arose out of one or more occurrences that took place on or prior to the time at which Executive signs this Agreement. Executive further represents and warrants that 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.

(a) 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 (as amended by Section 2(f) and Section 2(g)). In entering into this Agreement, Executive acknowledges the validity, binding effect and enforceability of Articles III, IV and V of the Severance Agreement (as amended by Section 2(f), Section 2(g) and Section 6(b)) and expressly reaffirms Executive’s commitment to abide by such provisions of the Severance Agreement. Notwithstanding the foregoing or the provisions of Section 16, below, as further consideration for Executive’s entry into this Agreement, the Company agrees that: (i) Executive’s obligation to return to the Company documents and other materials constituting or reflecting Confidential Information shall be limited to an obligation to return (and permanently delete from Executive’s personal computers, as applicable) such materials constituting or containing material, non-public information of or regarding the Company, the General Partner, or any of their respective Affiliates that Executive is able to locate or otherwise identify after a diligent search; (ii) in the event that Executive wishes to use or otherwise disclose information or materials created by them in the course of their Company employment that constitutes Confidential Information (but does not

5

constitute material, non-public information), then Executive may request permission to use or disclose such information from the General Counsel of the General Partner, and which permission shall not be unreasonably withheld; and (iii) notwithstanding Section 5.2 of the Severance Agreement, Executive may pursue business opportunities that Executive became aware of in the course of Executive’s employment or affiliation with the Company or the General Partners (the “Business Opportunities”) unless the Business Opportunities relates to (including if such Business Opportunity involves any acreage within) the Restricted Area and arises or otherwise occurs during the Prohibited Period (a “Restricted Business Opportunity”). If Executive wishes to pursue a Restricted Business Opportunity, then Executive may request permission to pursue such opportunity from the General Counsel of the General Partner, and which permission may be withheld, at the General Partner’s sole discretion, for any reason or no reason at all.

(b) As a further incentive for the Company and the General Partner to enter into this Agreement, and to further protect the Company’s and its Affiliates’ (as defined in the Severance Agreement) legitimate business interests, including the protection of Confidential Information and the preservation of their goodwill, Employee and the Company agree that, effective as of the Release Revocation Expiration Date, the definition of the term “Prohibited Period” within the Severance Agreement shall be modified so that, as of the Release Revocation Expiration Date, the term “Prohibited Period” within the Severance Agreement shall be interpreted and applied to mean the following: “the period during which Executive is employed by the Company or any of its Affiliates and continuing until the date that is 24 months following the Date of Termination.”

(c) 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, upon its 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.

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.

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.

9

(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.
