Dear Unitholders of Black Stone Minerals, L.P.:

Notice is hereby given that the 2016 annual meeting of limited partners (the “Annual Meeting”) of Black Stone Minerals, L.P. (the “Partnership”) will be held on May 26, 2016, at 2:00 p.m., local time, at the Hilton Americas-Houston, 1600 Lamar Street, Houston, Texas, 77010, for the following purposes:

1. to elect directors to the Board of Directors (the “Board”) of Black Stone Minerals GP, L.L.C., the general partner of the Partnership (the “General Partner”), each to serve until the 2017 annual meeting of limited partners and thereafter until such director’s successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, or removal;

2. to ratify the appointment of Ernst & Young LLP as the Partnership’s independent registered public accounting firm for the year ending December 31, 2016; and

3. to transact such other business as may properly come before the Annual Meeting or any postponements or adjournments thereof.

The Board of the General Partner has fixed the close of business on March 28, 2016 as the record date for the Annual Meeting. Holders of record of the Partnership’s common units, subordinated units, and preferred units as of the close of business on such date are entitled to notice of, and to vote at, the Annual Meeting.

Pursuant to the rules adopted by the Securities and Exchange Commission, the Partnership is providing access to its proxy materials primarily via the Internet, rather than mailing paper copies of these materials to each unitholder. On or about April 15, 2016, the Partnership began mailing a Notice of Internet Availability of Proxy Materials to its unitholders of record detailing how to access the proxy materials electronically and how to submit a proxy by telephone, Internet, or mail or vote in person at the Annual Meeting. The Notice of Internet Availability of Proxy Materials also provides instructions on how to request and obtain paper copies of the proxy materials.

If your units are held in street name, you will receive instructions from the holder of record detailing how to direct the voting of your units. Internet and/or telephone voting will also be offered to unitholders holding units in street name.

The Partnership urges you to review the proxy materials carefully and to submit your proxy or voting instructions as soon as possible so that your units will be represented at the Annual Meeting.

By Order of the Board of the General Partner,

Steve Putman

Senior Vice President, General Counsel, and

Secretary of Black Stone Minerals GP, L.L.C.

PROXY STATEMENT

FOR

ANNUAL MEETING OF LIMITED PARTNERS

TO BE HELD ON MAY 26, 2016

Unless the context clearly indicates otherwise, references in this Proxy Statement to “BSMC” or “our predecessor,” refer to Black Stone Minerals Company, L.P. and its subsidiaries for time periods prior to the initial public offering of Black Stone Minerals, L.P. on May 6, 2015 (the “IPO”), and references to “we,” “our,” “us,” “the Partnership,” or like terms refer to Black Stone Minerals, L.P. and its subsidiaries for time periods subsequent to the IPO.

This Proxy Statement is being furnished to you in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Black Stone Minerals GP, L.L.C., our general partner (the “General Partner”), for use at our 2016 annual meeting of limited partners (the “Annual Meeting”) to be held on May 26, 2016, at 2:00 p.m., local time, at the Hilton Americas-Houston, 1600 Lamar Street, Houston, Texas, 77010, and at any adjournment or postponement thereof. On or about April 15, 2016, we began mailing a Notice of Internet Availability of Proxy Materials to our unitholders of record detailing how to access the proxy materials electronically and how to submit a proxy by telephone, Internet, or mail or vote in person at the Annual Meeting. The Notice of Internet Availability of Proxy Materials also provides instructions on how to request and obtain paper copies of the proxy materials.

If your units are held in street name, you will receive instructions from the holder of record detailing how to direct the voting of your units. Internet and/or telephone voting will also be offered to unitholders holding units in street name.

GENERAL INFORMATION

Purpose of the Annual Meeting

The purpose of the Annual Meeting is for our unitholders to consider and act upon the proposals described in this Proxy Statement and upon any other matters that properly come before the Annual Meeting or any adjournment or postponement thereof. In addition, management will report on our performance and respond to questions from unitholders.

Proposals to be Voted Upon at the Annual Meeting

At the Annual Meeting, unitholders will be asked to consider and vote upon the following proposals:

1. Proposal 1: to elect directors to the Board of the General Partner, each to serve until the 2017 annual meeting of limited partners (the “2017 Annual Meeting”) and thereafter until such director’s successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, or removal; and

1

2. Proposal 2: to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2016.

In addition, any other matters that properly come before the Annual Meeting or any adjournments or postponements thereof will be considered. Management is not presently aware of any other business to properly come before the Annual Meeting.

Recommendation of the Board

The Board recommends that you vote “FOR ALL” the director nominees to the Board of the General Partner set forth in this Proxy Statement (Proposal 1) and “FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2016 (Proposal 2).

Right to Vote

Pursuant to the First Amended and Restated Agreement of Limited Partnership of Black Stone Minerals, L.P., dated May 6, 2015 (the “Partnership Agreement”), only holders of common units, subordinated units, and preferred units on the Record Date (as defined below) are entitled to notice of, and to vote at, the Annual Meeting. Such unitholders will vote together as a single class. Holders of common units and subordinated units are entitled to one vote per unit at the Annual Meeting, and holders of preferred units are entitled to vote their preferred units on an “as-converted basis.” The preferred units have a conversion rate of 30.3431 common units and 39.7427 subordinated units per preferred unit.

If any person or group (other than persons or groups who acquired their units with the prior approval of the Board of the General Partner) beneficially owns 15% or more of any class of common units, subordinated units, or preferred units as of the Record Date, that person or group will not be entitled to notice of, and to vote at, the Annual Meeting.

In addition, solely with respect to the election of directors, the Partnership Agreement provides that we and the General Partner are not entitled to vote our units, if any, and such units will not be counted when calculating the required votes for the election of directors and will not be deemed outstanding for purposes of determining a quorum for the Annual Meeting. These units will not be treated as a separate class of partnership securities for purposes of the Partnership Agreement.

The Board has fixed the close of business on March 28, 2016 as the record date (the “Record Date”) for the determination of unitholders entitled to notice of, and to vote at, the Annual Meeting. As of close of business on the Record Date, there were outstanding and entitled to vote 96,725,524 common units held by 479 holders of record, 94,948,090 subordinated units held by 940 holders of record, and 77,216 preferred units held by 146 holders of record (representing 2,342,971 common units and 3,068,760 subordinated units on an as-converted basis). In the aggregate, as of the Record Date there were outstanding and entitled to vote 197,085,345 units held by 1,565 holders of record.

A list of holders of record as of the Record Date will be available for inspection during ordinary business hours at our offices located at 1001 Fannin Street, Suite 2020, Houston, Texas, 77002 from April 15, 2016 to the date of our Annual Meeting. A copy of this list will be provided to you at no charge upon written request to Investor Relations at Black Stone Minerals, L.P. at the above listed address. The list will also be available for inspection by any unitholder present at the Annual Meeting.

Units held in nominee or street name account will be voted by the broker or other nominee in accordance with the instruction of the beneficial owner unless the arrangement between the beneficial owner and his nominee provides otherwise.

Voting Procedures

Registered Holders

If, on the Record Date, you hold units that are registered directly in your name with our transfer agent, American Stock Transfer & Trust Company LLC, you are considered a registered holder with respect to those units and entitled to notice of and to vote at the Annual Meeting. On or about April 15, 2016, we began mailing a Notice of Internet Availability of Proxy Materials to our registered holders of record detailing how to access the proxy materials electronically and how to submit a proxy by telephone, Internet, or mail or vote in person at the Annual Meeting. As a registered holder of record, you may vote your units by one of the following methods:

• By Internet. You may submit a proxy electronically via the Internet by following the on-screen instructions at www.voteproxy.com. Please have your Notice of Internet Availability of Proxy Materials, which includes your personal control number, in hand when you log onto the website. Internet voting facilities will close and no longer be available on the date and time specified on the Notice of Internet Availability of Proxy Materials.

• By Telephone. You may view the proxy materials and obtain the toll free number to call at www.voteproxy.com. Telephone voting facilities will close and no longer be available on the date and time specified on the proxy card.

• By Mail. If you request paper copies of the proxy materials, you may submit a proxy by signing, dating, and returning the proxy card in the pre-addressed envelope. If you wish to cumulate your votes, you must vote by using the proxy card rather than voting by telephone or the Internet.

• In Person. You may vote in person at the Annual Meeting by completing a ballot which will be provided at the Annual Meeting. However, attending the meeting without completing a ballot will not count as a vote. Please read “—Annual Meeting Admission.”

If you submit a proxy but do not give voting instructions as to how your units should be voted on a particular proposal at the Annual Meeting, your units will be voted in accordance with the recommendation of the Board as stated in this Proxy Statement. If you do not submit a proxy or attend the meeting and vote in person, your units will not be voted on the proposals or counted for the purpose of establishing a quorum at the Annual Meeting.

If you receive more than one Notice of Internet Availability of Proxy Materials, it is because your units are registered in more than one name or are registered in different accounts. Please follow the instructions on each Notice of Internet Availability of Proxy Materials received to ensure that all of your units are voted.

Beneficial Owners

If you hold units in an account with a brokerage firm, bank, or other nominee, then you are a beneficial owner with respect to these units and hold such units in “street name.” If you are a beneficial owner of units on the Record Date, the brokerage firm, bank, or other nominee (the “intermediary”) will provide instructions detailing how to direct the voting of your units through the intermediary. The intermediary that holds your units is considered the holder of record for purposes of voting at the Annual Meeting. Internet and/or telephone voting will also be offered to unitholders holding units in street name.

As a beneficial owner, you are also invited to attend the Annual Meeting. However, since you are not the holder of record, you may not vote your units in person at the Annual Meeting unless you obtain a signed proxy from the intermediary giving you the right to vote the units. Please read “—Annual Meeting Admission.”

If you do not vote your units in person or instruct the intermediary how to vote your units, the intermediary may vote your units as they decide for each matter for which they have discretionary authority under New York Stock Exchange (“NYSE”) rules. The election of directors (Proposal 1) is a non-discretionary matter for which

3

intermediaries do not have discretionary authority to vote unless they receive timely instruction from you. As such, for Proposal 1 to be voted on at the Annual Meeting, you must provide timely instructions on how the intermediary should vote your units. When an intermediary does not have discretion to vote on a particular matter, you have not given timely instructions on how the intermediary should vote your units, and the intermediary indicates it does not have authority to vote such units on its proxy, a “broker non-vote” results. Although any broker non-vote would be counted as present at the Annual Meeting for purposes of determining a quorum, it would be treated as not entitled to vote with respect to non-discretionary matters, and, as such, broker non-votes will not be counted as a vote “FOR” or “AGAINST” the election of directors. The ratification of the appointment of our independent registered public accounting firm for the year ending December 31, 2016 (Proposal 2) is a discretionary matter on which intermediaries may vote in the absence of timely instructions from you.

Annual Meeting Admission

Only unitholders of record or their legal proxy holders as of the Record Date or our invited guests may attend the Annual Meeting in person. If you plan to attend the Annual Meeting in person (regardless of whether you intend to vote your units in person at the Annual Meeting), you must present a valid form of government-issued photo identification. If you wish to attend the Annual Meeting and your units are held in street name with an intermediary, you will need to bring a copy of your brokerage statement or other documentation reflecting your unit ownership as of the Record Date.

The Annual Meeting will be held at the Hilton Americas-Houston, 1600 Lamar Street, Houston, Texas, 77010.

Revoking Your Proxy

If you are a registered holder, you may change your vote or revoke your proxy at any time before the units are voted at the Annual Meeting by:

• timely delivering a valid, later-dated, executed proxy card;

• timely submitting a proxy with new voting instructions through the Internet or by telephone;

• voting in person at the Annual Meeting by completing a ballot (attending the meeting without completing a ballot will not revoke any previously submitted proxy); or

• filing a written notice of revocation on or before the date of the Annual Meeting with the General Counsel of Black Stone Minerals, L.P. at 1001 Fannin Street, Suite 2020, Houston, Texas, 77002.

If you are a beneficial owner and you submit voting instructions to your intermediary, you may change your vote by submitting new voting instructions in accordance with such intermediary’s procedures.

Quorum

The holders of a majority of the common units, subordinated units, and preferred units (on an as-converted basis), in the aggregate, represented in person or by proxy shall constitute a quorum at the Annual Meeting, unless any such action requires approval by holders of a greater percentage of the units in which case the quorum shall be the greater percentage. Proxies received but marked as abstentions and broker non-votes will be included in the number of units considered to be present at the Annual Meeting for purposes of establishing a quorum. The unitholders present at a duly called or held meeting at which a quorum is present may continue to transact business until adjournment, notwithstanding the withdrawal of enough unitholders to leave less than a quorum. In the absence of a quorum, the Annual Meeting may be adjourned from time to time until a quorum is obtained, but no other business may be transacted, except as otherwise provided in the Partnership Agreement.

4

Required Votes

Election of Directors (Proposal 1)

Pursuant to the Partnership Agreement, the directors of the Board of the General Partner are elected by a plurality of the votes cast by the unitholders entitled to vote at the Annual Meeting. Each unitholder entitled to vote at the Annual Meeting is entitled to cumulate his or her votes in the election of directors and give one candidate, or divide among any number of candidates, a number of votes equal to the product of (x) the number of common units, subordinated units, and preferred units (on an as-converted basis) held by the unitholder, multiplied by (y) the number of directors to be elected at the Annual Meeting. Abstentions and broker non-votes will be counted for purposes of establishing quorum but otherwise will have no effect on the election of directors.

Ratification of our Independent Registered Public Accounting Firm (Proposal 2)

Pursuant to the Partnership Agreement, the proposal to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2016 requires approval by the holders of a majority of the common units, subordinated units, and preferred units (on an as-converted basis) entitled to vote at the Annual Meeting. Abstentions will be counted for purposes of establishing quorum but otherwise will have no effect on this proposal. Because intermediaries will have discretion to vote units without the direction of their clients with respect to this proposal, there will not be any broker non-votes with respect to this proposal.

Solicitation of Proxies

This solicitation of proxies is being made by the Board of the General Partner, and we will bear all costs incurred in the solicitation of proxies. This includes the charges and expenses of brokerage firms and others for forwarding solicitation material to beneficial owners of our units. We may solicit proxies by mail, telephone, or via the Internet through our executive officers, directors, and other management employees, who will receive no additional compensation for their services.

2015 Annual Report

Our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 is available on our website at www.blackstoneminerals.com in the “SEC Filings” subsection of the “Investors” section. A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2015, including the financial statements and the financial statement schedules, if any, but not including exhibits, will be furnished at no charge to each unitholder to whom a Notice of Internet Availability of Proxy Materials is delivered upon the written request of such person addressed to Investor Relations at Black Stone Minerals L.P., 1001 Fannin Street, Suite 2020, Houston, Texas, 77002.

PROPOSAL 1—ELECTION OF DIRECTORS

At the recommendation of the nominating and governance committee of the Board, the Board of the General Partner has nominated the following individuals for election as directors of the Board of the General Partner, each to serve until the 2017 Annual Meeting and thereafter until such director’s successor shall have been duly elected and qualified, or until such director’s earlier death, resignation, or removal:

Each director nominee is currently serving on the Board of the General Partner. Certain individual qualifications and skills of our directors that contribute to the Board’s effectiveness as a whole are described below in each director’s biographical information under the heading “Executive Officers and Directors.”

The election of directors in this Proposal 1 requires the affirmative vote of a plurality of the votes cast by the unitholders entitled to vote at the Annual Meeting. Each unitholder entitled to vote at the Annual Meeting is entitled to cumulate his or her votes in the election of directors and give one candidate, or divide among any number of candidates, a number of votes equal to the product of (x) the number of common units, subordinated units, and preferred units (on an as-converted basis) held by the unitholder, multiplied by (y) the number of directors to be elected at the Annual Meeting. Abstentions and broker non-votes will have no effect on the election of directors.

Unless otherwise indicated on the proxy, the persons named as proxies will vote “FOR ALL” of the nominees listed above. Although we have no reason to believe that any of the nominees will be unable to serve if elected, should any of the nominees become unable to serve prior to the Annual Meeting, the proxies will be voted for the election of such other persons as may be nominated by the Board of the General Partner.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR ALL” OF THE DIRECTOR NOMINEES.

GOVERNANCE MATTERS

Corporate Governance Guidelines

The Board of the General Partner believes that sound governance practices and policies provide an important framework to assist it in fulfilling its duty to unitholders. Our Corporate Governance Guidelines cover the following principal subjects:

• the size of the Board;

• qualifications and independence standards for the Board;

• director responsibilities;

• meetings of the Board and of non-management directors;

• committee functions and independence of committee members;

• compensation of the Board;

• self-evaluation and succession planning;

• unitholder communications with directors; and

• access to management and to independent advisors.

The Corporate Governance Guidelines are available on our web site at www.blackstoneminerals.com under the “Corporate Governance” subsection of the “Investors” section. The Corporate Governance Guidelines will be reviewed periodically and as necessary by our nominating and governance committee, and any proposed additions to or amendments of the Corporate Governance Guidelines will be presented to the Board of the General Partner for its approval.

The NYSE has adopted rules that require listed companies to adopt governance guidelines covering certain matters. We believe that the Corporate Governance Guidelines comply with the NYSE rules.

Board Leadership Structure

The Board’s leadership structure does not separate the Chief Executive Officer and Chairman of the Board positions. The Board retains the authority to modify this structure as and when appropriate, and it is possible that the Board may decide to separate the Chief Executive Officer and Chairman of the Board positions in the future.

The Board believes that there is no single, generally accepted approach to providing Board leadership and that each of the possible leadership structures for a board must be considered in the context of the individuals involved and the specific circumstances facing a company as the right leadership structure may vary as circumstances change. The Board currently is of the view that it is in our best interest for the Chief Executive Officer to also serve as the Board’s Chairman. Mr. Carter serves as our President and Chief Executive Officer as well as Chairman of the Board. As the director most familiar with our business and industry and most capable of effectively identifying strategic priorities, he is best positioned to lead the Board through reviews of key business and strategic issues.

Executive Sessions of Non-Management Directors

The Board of the General Partner holds regular executive sessions in which the non-management directors meet without any members of management present. The purpose of these executive sessions is to promote open and candid discussion among the non-management directors. The director who presides at these meetings, the lead director, rotates among the chairpersons of the Board’s committees. The lead director is responsible for preparing an agenda for the meetings of the non-management directors in executive session. Currently, all of the non-management directors of the Board are independent under the listing requirements of the NYSE.

12

Risk Oversight Procedures

The Board of the General Partner as a whole oversees our assessment of major risks and the measures taken to manage such risks. For example, the Board:

• oversees our long-term strategic plans, assesses risks that would cause us to fail to achieve our strategic plans and reviews strategies to mitigate those risks;

• oversees management of our exposure to commodity prices through regular review of our hedging position and hedging policy;

• monitors our liquidity profile and our compliance with the financial covenants contained in our borrowing arrangements; and

• has established specific dollar limits on the commitment authority of members of management for certain transactions and requires Board approval of expenditures exceeding that authority and of other material contracts and transactions.

The audit committee is responsible for overseeing and discussing with management our guidelines and policies with respect to risk assessment and risk management, including our major financial risk exposures and the steps management has taken to monitor and control such exposures as well as the risks associated with our hedging strategy. The compensation committee is responsible for reviewing our incentive compensation arrangements to determine whether they encourage excessive risk-taking. It also reviews and discusses the relationship between risk management policies and practices and compensation and evaluates compensation policies and practices that could mitigate any such risk. The Board of the General Partner does not consider its role in oversight of our risk management function to be relevant to its choice of leadership structure.

Director Independence

The Board has determined that Mr. Bardel, Ms. Barth, Mr. DeWalch, Mr. Haeflinger, Mr. Kyle, Mr. Linn, Mr. Longmaid, Mr. Mathis, Mr. Sinclair, Mr. Stuart, and Ms. Thacker are independent as defined by the rules of the NYSE and under Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Committees of the Board

The Board of the General Partner has the following standing committees: audit committee, compensation committee, and nominating and governance committee. The Board will appoint a conflicts committee as necessary. The audit committee, the compensation committee, and the nominating and governance committee each have a written charter approved by the Board of the General Partner. Each of these written charters is available on our web site at www.blackstoneminerals.com under the “Corporate Governance” subsection of the

13

“Investors” section. Summaries of the functions performed by and the membership of each committee of the Board are set forth below.

* Financial Expert

Audit Committee

We are required to have an audit committee of at least three members, and all its members are required to meet the independence and experience standards established by the NYSE and Rule 10A-3 promulgated under the Exchange Act. Ms. Barth and Messrs. Haeflinger, Mathis, and Kyle currently sit on the audit committee, with Ms. Barth acting as the committee chairperson. The Board has also determined that Ms. Barth qualifies as an “audit committee financial expert,” as such term is defined under Securities and Exchange Commission (“SEC”) rules.

The audit committee assists the Board in its oversight of (i) the integrity of our financial statements, (ii) our compliance with legal and regulatory requirements, (iii) qualifications and independence of our independent registered public accounting firm, and (iv) performance of our internal audit function and independent registered public accounting firm. The audit committee has the sole authority to retain and terminate our independent registered public accounting firm, approve all auditing services and related fees and the terms thereof performed by our independent registered public accounting firm, and pre-approve any non-audit services and tax services to be rendered by our independent registered public accounting firm. The audit committee is also responsible for confirming the independence and objectivity of our independent registered public accounting firm. Our independent registered public accounting firm is given unrestricted access to the audit committee and our management, as necessary.

Compensation Committee

Because we are a limited partnership, we are not required by the rules of the NYSE to have a compensation committee or a compensation committee composed entirely of independent directors. However, we nevertheless have a compensation committee, and all of its members meet the independence standards established by the NYSE. Messrs. Bardel, Linn, Longmaid, and Stuart currently sit on the compensation committee, with Mr. Bardel acting as the committee chairperson.

The compensation committee reviews and determines the compensation for the executive officers of the General Partner and reviews and makes recommendations to the Board of the General Partner regarding director compensation. The compensation committee also administers our incentive compensation and equity-based benefit plans.

14

The compensation committee is delegated all authority of the Board of the General Partner as may be required or advisable to fulfill its purposes. The compensation committee may delegate to any subcommittee it may form, the responsibility and authority for any particular matter, as it deems appropriate from time to time under the circumstances. Meetings may, at the discretion of the compensation committee, include members of management, other members of the Board, consultants or advisors, and such other persons as the compensation committee believes to be necessary or appropriate. The compensation committee will consult with our Chief Executive Officer when evaluating the performance of, and setting the compensation for, our executive officers other than the Chief Executive Officer.

The compensation committee may, in its sole discretion, retain and determine funding for legal counsel, compensation consultants, as well as other experts and advisors (collectively, “Committee Advisors”), including the authority to retain, approve the fees payable to, amend the engagement with and terminate any Committee Advisor, as it deems necessary or appropriate to fulfill its responsibilities. In 2015, the compensation committee engaged Frederick W. Cook & Co., Inc. (“F.W. Cook”) directly as its independent compensation consultant to assist the committee with its responsibilities related to our executive officer and director compensation programs. A representative of F.W. Cook attends compensation committee meetings, as requested, and communicates with the chair of the compensation committee between meetings. However, the compensation committee makes all decisions regarding the compensation of our executive officers and directors. F.W. Cook reports directly to the compensation committee and all work conducted by F.W. Cook for us is on behalf of the committee.

The compensation committee regularly reviews the services provided by its outside consultant and believes that F.W. Cook is independent under applicable SEC rules in providing executive compensation consulting services. In making this determination, the committee noted that during fiscal 2015:

• F.W. Cook did not provide any services to us or our management other than services requested by or with the approval of the compensation committee, which were limited to executive officer and director compensation consulting;

• F.W. Cook maintains a conflicts policy, which was provided to the compensation committee, with specific policies and procedures designed to ensure independence;

• We have been advised by F.W. Cook that the fees we paid to F.W. Cook in 2015 were less than 1% of F.W. Cook total revenue;

• None of the F.W. Cook consultants working on our matters had any business or personal relationship with any compensation committee members;

• None of the F.W. Cook consultants working on our matters had any business or personal relationship with any of our executive officers; and

• None of the F.W. Cook consultants working on our matters owns our units.

The compensation committee continues to monitor the independence of F.W. Cook on a periodic basis.

Nominating & Governance Committee

Because we are a limited partnership, we are not required by the rules of the NYSE to have a nominating and governance committee or a nominating and governance committee composed entirely of independent directors. However, we nevertheless have a nominating and governance committee, and all of its members meet the independence standards established by the NYSE. Ms. Thacker and Messrs. Mathis, DeWalch, and Sinclair currently sit on the nominating and governance committee, with Mr. Mathis acting as the committee chairperson.

The nominating and governance committee identifies individuals qualified to serve on the Board of the General Partner and recommends director nominees for each annual meeting of limited partners or for appointment to fill vacancies, oversees our governance policies, and oversees the evaluation of the Board and its committees.

15

Conflicts Committee

At least one independent member of the Board will serve on a conflicts committee, as necessary, to review specific matters that the Board believes may involve conflicts of interest. The conflicts committee will determine if the resolution of the conflict of interest is, in its subjective belief, not adverse to our interest. The members of the conflicts committee may not be officers or employees of the General Partner or directors, officers, or employees of its affiliates and must meet the independence standards established by NYSE and the Exchange Act rules to serve on an audit committee of a board of directors, along with the requirements in the Partnership Agreement. Any matters approved by the conflicts committee will be conclusively deemed to be approved by us and all of our unitholders and not a breach by the General Partner of any duties or contractual obligations it may owe us or our unitholders.

Board and Committee Meeting Attendance

Since the IPO in May 2015, the Board of the General Partner held seven regularly scheduled and special meetings of the full Board, the audit committee held seven meetings, the compensation committee held two meetings, and the nominating and governance committee held three meetings. All directors and committee members attended at least 75% of the aggregate number of meetings of the Board and committees of the Board on which they served, other than Mr. Linn, who attended 70%.

Director Attendance at Annual Meetings of Limited Partners

Directors are encouraged, but not required, to attend the annual meetings of limited partners.

Director Nominations

Nominations of persons for election to the Board of the General Partner may be made at an annual meeting of the limited partners or, provided that the Board or unitholders have determined that directors will be elected at such a meeting, a special meeting of the limited partners, in any such case only pursuant to the General Partner’s notice of meeting (or any supplement thereto), (a) by or at the direction of the Board or any committee thereof, or (b) by any unitholder or group of unitholders who (1) is entitled to vote at the meeting, (2) complies with the notice procedures set forth in the Partnership Agreement, and (3) either individually or as a group hold units representing at least 10% of the outstanding units (measured on a fully diluted basis and treating the preferred units on an as-converted basis) both at the time of giving notice of such nomination and at the meeting.

Nominations of Director Candidates by the Board

The Board of the General Partner is responsible for nominating persons for election to the Board and filling vacancies on the Board that may occur between annual meetings. The Board believes that all directors must possess a considerable amount of management experience (such as experience as an executive), a solid financial background, and oil and gas related business or investment experience. The nominating and governance committee is responsible for establishing criteria for the selection of new Board members and identifying (taking into account all factors the committee considers appropriate), evaluating, and recommending candidates to the Board of the General Partner for prospective Board membership. The committee also considers matters relating to the retirement of Board members, including term limits or age limits, attendance at Board and committee meetings, conflicts of interest, and other relevant factors. The nominating and governance committee does not have a formal policy with respect to diversity.

Nomination of Director Candidates by Unitholders

Unitholders may nominate directors for election to the Board of the General Partner, provided that they comply with the requirements described below and in the section of this Proxy Statement entitled “Proposals and Nomination of Director Candidates for the 2017 Annual Meeting.” While we do not have a policy that

16

specifically addresses the consideration of director candidates recommended by unitholders, there would be no differences in the manner and criteria by which the nominating and governance committee and the Board evaluate director candidates recommended by unitholders and those recommended by other sources.

For any nominations brought before an annual meeting by a nominating unitholder, the unitholder must give timely notice thereof in writing to the General Partner. The notice must contain certain information as described in the Partnership Agreement. To be timely, the nomination notice must be delivered to the General Partner not later than the close of business on the 90th day, nor earlier than the close of business on the 120th day, prior to the first anniversary of the preceding year’s annual meeting (provided, however, that in the event that the date of the annual meeting is more than 30 days before or more than 70 days after the anniversary date, the nomination notice must be so delivered not earlier than the close of business on the 120th day prior to the annual meeting and not later than the close of business on the later of the 90th day prior to the annual meeting or the 10th day following the day on which public announcement of the date of the meeting is first made by us or the General Partner). The public announcement of an adjournment or postponement of an annual meeting will not commence a new time period (or extend any time period) for the giving of a nominating unitholder’s notice as described above.

In the event that the number of directors to be elected to the Board of the General Partner is increased effective at the annual meeting and there is no public announcement by us or the General Partner naming the nominees for the additional directorships at least 100 days prior to the first anniversary of the preceding year’s annual meeting, the nomination notice will also be considered timely, but only with respect to nominees for the additional directorships, if it shall be delivered to the General Partner not later than the close of business on the 10th day following the day on which a public announcement is first made by us or the General partner.

Nominations of persons for election to the Board also may be made at a special meeting of limited partners at which directors are to be elected in accordance with the Partnership Agreement.

Only persons who are nominated in accordance with the procedures set forth in the Partnership Agreement will be eligible to be elected at an annual or special meeting of limited partners to serve as directors. Notwithstanding the foregoing, unless otherwise required by law, if the unitholder (or a qualified representative of the unitholder) does not appear at the annual or special meeting of unitholders to present a nomination, the nomination shall be disregarded notwithstanding that proxies in respect of a vote may have been received by the General Partner or us.

In addition to the provisions described above and in the Partnership Agreement, a unitholder must also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder; provided, however, that any references in the Partnership Agreement to the Exchange Act or the rules promulgated thereunder are not intended to and do not limit any requirements applicable to nominations pursuant to the Partnership Agreement, and compliance with the Partnership Agreement is the exclusive means for a unitholder to make nominations.

Communication with the Board

A holder of our units or other interested party who wishes to communicate with the directors of the General Partner may do so by sending communications to the Board, any committee of the Board, the non-management directors, the Chairman of the Board, or any other director by telephone at (713) 445-3200, or in writing to 1001 Fannin Street, Suite 2020, Houston, Texas, 77002 by marking the envelope containing each communication as “Unitholder Communication with Directors” and clearly identifying the intended recipient(s) of the communication. Communications will be relayed to the intended recipient of the Board except in instances where it is deemed unnecessary or inappropriate to do so pursuant to our guidelines, which are available on our website at www.blackstoneminerals.com in the “Corporate Governance” subsection under the “Investors” section. Any communications withheld under those guidelines will nonetheless be retained and available for any director who wishes to review them.

17

Code of Ethics

We have a Code of Business Conduct and Ethics that applies to our directors, officers, and employees as well as a Financial Code of Ethics that applies to our Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer and the other senior financial officers, each as required by NYSE and SEC rules. Each of the foregoing is available on our website at www.blackstoneminerals.com in the “Corporate Governance” subsection of the “Investors” section. We will provide copies, free of charge, of any of the foregoing upon receipt of a written request to Investor Relations at Black Stone Minerals, L.P., 1001 Fannin Street, Suite 2020, Houston, Texas 77002. We intend to disclose amendments to and waivers, if any, from our Code of Business Conduct and Ethics and Financial Code of Ethics, as required, on our website, www.blackstoneminerals.com, promptly following the date of any such amendment or waiver.

Procedures for Review, Approval, and Ratification of Transactions with Related Persons

Under our Code of Business Conduct and Ethics, a director is expected to bring to the attention of the Chief Executive Officer or the Board of the General Partner any conflict or potential conflict of interest that may arise between the director or any affiliate of the director, on the one hand, and us or the General Partner on the other. The resolution of any conflict or potential conflict should, at the discretion of the Board and in light of the circumstances, be determined by a majority of the disinterested directors.

In addition, under the Code of Business Conduct and Ethics, any executive officer is required to avoid conflicts of interest unless approved in advance by the Board.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires the directors and executive officers of the General Partner and persons who own more than 10% of a registered class of our equity securities to file reports of beneficial ownership on Form 3 and reports of changes in beneficial ownership on Form 4 or Form 5 with the SEC. Based solely on our review of the reporting forms and written representations provided to us from the individuals required to file reports, we believe that each of our executive officers and directors has complied with the applicable reporting requirements for transactions in our securities during the year ended December 31, 2015, except for the following:

Due to a clerical error, in his Form 4 filed May 8, 2015, Mr. Bardel underreported the number of common units acquired in connection with the IPO on May 6, 2015, by 10 common units. These 10 common units were reported in a Form 4/A filed on June 15, 2015.

(1) Amounts include elective deferrals made by our Named Executive Officers under the Black Stone Energy Company 401(k) Plan (the “401(k) Plan”).

(2) Amounts for 2014 reflect the grant date fair value of common units in our predecessor, computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 (“FASB ASC Topic 718”), which awards were converted into an equivalent number of our common and subordinated units as part of the IPO. Amounts for 2015 reflect the grant date fair value of our common and subordinated units, computed in accordance with FASB ASC Topic 718. For the portion of the amounts reported in this column that are attributable to performance units granted to our NEOs (discussed further below under “Narrative Disclosure to the Summary Compensation Table—Long-Term Incentive Awards—Awards Granted in connection with Our Initial Public Offering”), such amounts reflect a grant date value assuming that our adjusted operating surplus for each performance period is achieved at the target level. The maximum value that could potentially be paid pursuant to such awards would be $5,597,932 for Mr. Carter and $6,299,564 for each of Messrs. Carroll and Dorn. See Note 10 to our consolidated financial statements for additional detail regarding assumptions underlying the value of these equity awards.

(3) Amounts reflect (i) short-term incentive bonus (“STI Bonus”) awards earned by each NEO in 2014 and 2015 and (ii) performance-based cash incentive awards under the BSMC 2012 Executive Incentive Plan (the “EIP”) earned by each NEO in 2014 and 2015. Please read “—Narrative Disclosure to the Summary Compensation Table—Short-Term Incentive Bonuses” for additional details regarding the STI Bonus awards. Please read “—Narrative Disclosure to the Summary Compensation Table—Long-Term Incentive Awards” for additional details regarding the performance-based cash incentive awards under the EIP.

(4) The amounts included in “All Other Compensation” reflect (i) for Mr. Carter: matching contributions equal to $13,000 and $13,250 that were made to the 401(k) Plan on his behalf in 2014 and 2015, respectively, and reimbursement in 2014 for his personal use of private aircraft in an amount equal to $106,286; (ii) for Mr. Carroll: matching contributions equal to $13,000 and $13,250 that were made to the 401(k) Plan on his behalf in 2014 and 2015, respectively; and (iii) for Mr. Dorn: matching contributions equal to $13,000 and $13,250 that were made to the 401(k) Plan on his behalf in 2014 and 2015, respectively.

Narrative Disclosure to the Summary Compensation Table

For fiscal 2015 and 2014, the principal elements of compensation provided to our Named Executive Officers were base salaries, STI Bonuses, long-term incentive awards, and retirement, health, welfare, and additional benefits.

Base Salary

Base salaries are generally set at levels deemed necessary to attract and retain individuals with superior talent commensurate with their relative expertise and experience.

Short-Term Incentive Bonuses

The STI Bonus opportunity is based upon our pay-for-performance philosophy. The STI Bonus provides our NEOs with an incentive in the form of an annual cash bonus to achieve our overall business goals. The STI Bonuses for fiscal 2014 and 2015 were equal to the product of each NEO’s (i) target bonus and (ii) our EBITDA achievement factor (the “EBITDA Adjustment Factor”) for 2014 and 2015 as reflected below.

Name	Year		Target Bonus Value		EBITDA Adjustment Factor(1)		Actual Bonus Earned
Thomas L. Carter, Jr.		2015	$	803,400		0.91597382	$	735,893
		2014	$	803,400		1.2143069	$	975,574
Marc Carroll		2015	$	386,250		0.91597382	$	353,795
		2014	$	386,250		1.2143069	$	469,026
Holbrook F. Dorn		2015	$	350,000		0.91597382	$	320,591
		2014	$	334,750		1.2143069	$	406,489

(1) For purposes of calculating Messrs. Carter’s, Carroll’s, and Dorn’s 2014 and 2015 STI Bonuses, the EBITDA achievement ratio was calculated as the ratio of our actual adjusted EBITDA for the applicable year to our budgeted adjusted EBITDA for such year, as adjusted by an EBITDA Adjustment Factor that accelerates the effect of under- or over-achievement such that an EBITDA achievement ratio of 1.3 or more results in a 200% maximum EBITDA Adjustment Factor, an EBITDA achievement ratio of 0.7 results in a 50% threshold-EBITDA Adjustment Factor, and an EBITDA achievement ratio of less than 0.7 results in a 0% EBITDA Adjustment Factor, with linear interpolations between the target (100%) and either the threshold or maximum, as applicable. For this purpose, (a) our actual adjusted EBITDA for the applicable year was calculated as the sum of our (i) net income, (ii) interest expense, (iii) income tax expense, (iv) depreciation, depletion, amortization, and impairment expense, (v) targeted compensation associated with grants or issuances of equity interests (including carried interests in real property) to employees or members of the Board or associated with our incentive or retention plans or agreements (whether cash or equity), and (vi) dry hole expense, as determined in accordance with GAAP, consistently applied and (b) our budgeted adjusted EBITDA for the applicable year was the adjusted EBITDA amount projected in the annual budget for such year approved by the Board.

Long-Term Incentive Awards

Awards under 2012 Executive Incentive Plan and Converted Restricted Unit Awards

In fiscal 2014 and 2015, each of our NEOs was granted a target incentive award. 50% of each target incentive award consists of a performance-based cash incentive award under the EIP. The performance-based cash incentive awards “cliff” vest at the end of a three-year performance period so long as the NEO remains continuously employed by Black Stone Natural Resources Management Company (“BSNRMC”), a subsidiary of us, or one of its affiliates through such date, subject to certain exceptions discussed below under “Additional

20

Narrative Disclosure—Potential Payments Upon Termination or a Change in Control—2012 Executive Incentive Plan and Restricted Unit Award Agreements.” The ultimate amount paid in respect of each cash incentive award is determined based on the achievement of certain reserve and production targets established by the compensation committee of the Board.

The remaining 50% of each target incentive award consisted of common units in our predecessor granted pursuant to Restricted Unit Award Agreements entered into with each NEO. In connection with the IPO in May 2015, all unvested units in our predecessor held by our NEOs were exchanged for an aggregate of 210,495 restricted common units and 275,704 restricted subordinated units pursuant to the Black Stone Minerals, L.P. Long-Term Incentive Plan (the “LTIP”) and each NEO’s Restricted Unit Award Agreement was replaced with a Converted Restricted Unit Grant Notice and Converted Restricted Unit Agreement. Under such replacement agreements, the restricted common units and restricted subordinated units vest in accordance with the original schedule that applied to the pre-conversion awards from our predecessor, as set forth in the Converted Restricted Unit Award Vesting Schedule below and so long as the NEO remains continuously employed by BSNRMC, or one of its affiliates through each such date, subject to certain exceptions discussed below under “Additional Narrative Disclosure—Potential Payments Upon Termination or a Change in Control—Converted Restricted Unit Agreements.” A portion of each NEO’s converted restricted common and subordinated units vested on January 1, 2016 and March 15, 2016.

Converted Restricted Unit Award Vesting Schedule

January 1, 2013	January 1, 2016
January 1, 2014	January 1, 2016
	January 1, 2017
February 23, 2015	March 15, 2016
	March 15, 2017
	March 15, 2018

Awards Granted in connection with Our Initial Public Offering

In connection with the IPO in May 2015, the Board granted awards under the LTIP to each of our NEOs consisting of 331,554 restricted common units and 478,870 performance units in the aggregate that, if earned at target levels of performance and vested, will be settled in the form of common units. Each award is subject to the terms and conditions of the LTIP and award agreement that we entered into with the applicable NEO.

In particular, our NEOs were each granted performance units that become earned over four 12-month performance periods, commencing April 1, 2015, based on our adjusted operating surplus (as defined in the Partnership Agreement relative to a target amount for each performance period and, for the fourth performance period only, also based on the expiration of the subordination period (as defined in the Partnership Agreement), in each case, so long as the NEO remains continuously employed by BSNRMC or one of its affiliates through each such date, subject to certain exceptions discussed below under “Additional Narrative Disclosure—Potential Payments Upon Termination or a Change in Control—IPO Award Agreements.” Pursuant to the terms of his award agreement, each NEO has the opportunity for a makeup performance period following the expiration of the fourth performance period if the foregoing performance metrics were not achieved in the fourth performance period. The performance unit awards also include tandem distribution equivalent rights that entitle each NEO to cash payments equal to the distribution paid to our common unitholders during the applicable performance period.

In addition, Messrs. Carroll and Dorn were granted time-based restricted common units that vest ratably on March 15 of each of 2016, 2017, 2018, and 2019, so long as the NEO remains continuously employed by

21

BSNRMC or one of its affiliates through each such date, subject to certain exceptions discussed below under “Additional Narrative Disclosure—Potential Payments Upon Termination or a Change in Control—IPO Award Agreements.”

Additional Narrative Disclosure

Retirement Benefits

We have not maintained, and do not currently maintain, a defined benefit pension plan or a nonqualified deferred compensation plan providing for retirement benefits. Our NEOs currently participate in the 401(k) Plan, which permits all eligible employees, including the NEOs, to make voluntary pre-tax contributions to the plan. In addition, we are permitted to make discretionary matching contributions under the plan. Matching contributions are subject to a graded vesting schedule, with 33% vested after one year, 66% vested after two years, and 100% vested after the initial three years of employment with us. Following three years of employment, future company matching contributions vest immediately. All contributions under the plan are subject to certain annual dollar limitations, which are periodically adjusted for changes in the cost of living.

Potential Payments Upon Termination or a Change in Control

Each of our NEOs may be entitled to certain severance and other benefits upon a termination of employment under the terms of their respective award agreements and severance agreements, as described in further detail below. The description of the relevant terms of such award agreements and severance agreements set forth below does not purport to be a complete description of all of the provisions of any such agreements and is qualified in its entirety by reference to the forms of award agreements and severance agreements previously filed with the SEC.

Severance Agreements

We previously had an employment agreement with Mr. Carter, however, Mr. Carter’s employment agreement was terminated in connection with the IPO. Each of our NEOs entered into a severance agreement with BSNRMC in connection with the IPO that, among other things, provides for the payment of cash severance payments and benefits in the event the executive officer’s employment is terminated under certain circumstances.

More specifically, each NEO’s severance agreement provides that if the executive officer’s employment is terminated without “cause” or the executive officer resigns for “good reason,” then so long as the executive officer executes (and does not revoke within any time provided to do so) a release in a form satisfactory to BSNRMC within the applicable time period specified in the severance agreement, the executive officer will receive the following severance payments and benefits: (a) a lump sum cash severance payment equal to the sum of: (i) an amount equal to 1.0 (or, in the case of Mr. Carter, 2.0) times the sum of the executive officer’s annualized base salary and target annual bonus as in effect on the date of such termination (or, if such termination occurs within 24 months following a “change in control,” an amount equal to 2.0 (or, in the case of Mr. Carter, 3.0) times the sum of the executive officer’s annualized base salary and target annual bonus as in effect on the date of such termination); (ii) a pro-rated portion of the executive officer’s target bonus for the calendar year that includes the date of such termination; and (iii) any earned but unpaid bonus for the calendar year preceding the calendar year that includes the date of such termination; and (b) monthly cash reimbursement for the amount the executive officer pays for continuation coverage under our affiliates’ group health plans for up to 12 months following such termination (or, if such termination occurs within 24 months following a change in control, for up to 24 months following such termination).

Under each severance agreement:

• “cause” generally means a determination by two-thirds of the Board that the applicable executive officer has: (a) willfully and continually failed to substantially perform the officer’s duties;

23

(b) willfully engaged in conduct that is demonstrably and materially injurious to us or any of our affiliates; (c) been convicted of, or has plead guilty or nolo contendere to, a misdemeanor involving moral turpitude or a felony; (d) committed an act of fraud, or material embezzlement or material theft; or (e) materially breached any of the officer’s obligations under the severance agreement or any other written agreement entered into between the officer and us or any of our affiliates;

• “good reason” generally means the occurrence of any of the following events without the applicable executive officer’s written consent: (a) a reduction in the officer’s total compensation other than a general reduction in compensation that affects all similarly situated employees in substantially the same proportions; (b) a relocation of the officer’s principal place of employment by more than 50 miles; (c) a material breach by us or any of our affiliates of the severance agreement or any other written agreement with the officer; (d) a material, adverse change in the officer’s title, authority, duties or responsibilities; (e) a material adverse change in the reporting structure applicable to the officer; (f) following a change in control, the failure to continue (or the taking of any action that adversely affects the officer’s participation in) any benefit plan or compensation arrangement in which the officer was participating immediately prior to such change in control; or (g) in the case of Mr. Carter, the General Partner’s failure to nominate Mr. Carter for election to the Board and to use its best efforts to have Mr. Carter elected and re-elected, as applicable;

• “change in control” generally means (a) the acquisition of beneficial ownership of more than 50% of our common units and subordinated units; (b) the complete liquidation of the partnership; (c) the sale of all or substantially all of our assets to any person other than one of our affiliates; (d) the occurrence of a transaction resulting in the General Partner or one of its affiliates ceasing to be our sole general partner; (e) the failure of the individuals who constitute the “incumbent board” of the General Partner to constitute at least a majority of the Board; or (f) the occurrence of a transaction resulting in us ceasing to own, directly or indirectly, 100% of the outstanding equity interests of the General Partner; and

• “disability” generally means an executive officer’s inability to perform the essential functions of his or her position with us, with reasonable accommodation, for a period of at least 90 consecutive days or 120 days in any 12-month period.

The severance agreements also contain certain restrictive covenants pursuant to which our executive officers recognize an obligation to comply with, among other things, certain confidentiality covenants as well as covenants not to compete in a defined market area with us or any of our affiliates or solicit any of our affiliates’ employees, in each case, during the term of the agreement and for a period of one year (or, in the case of Mr. Carter, two years) thereafter.

2012 Executive Incentive Plan and Converted Restricted Unit Agreements

Under the EIP, if a NEO’s employment terminates due to his death or “disability” or his employment is involuntarily terminated for any other reason other than “cause,” the NEO (or the NEO’s estate, as applicable) will be entitled to receive a pro-rated portion of each cash incentive award for each performance period that includes the NEO’s termination date. For purposes of the EIP, “cause” and “disability” generally have the same meanings provided above under the severance agreements.

In addition, pursuant to the Converted Restricted Unit Agreements, if a NEO’s employment is terminated without “cause” or if the NEO resigns for “good reason,” subject to the NEO’s execution and non-revocation of a release, a pro-rated portion of the NEO’s unvested common units and unvested subordinated units will become vested as of such termination so long as the NEO has remained continuously employed between the date of grant through the date of such termination of employment; provided that if such termination of employment occurs within 24 months following a “change of control” or such termination occurs as a result of the NEO’s “disability” or death, all of the NEO’s unvested common units and unvested subordinated units will become

24

vested as of such termination. For purposes of the Converted Restricted Unit Agreement, “cause,” “disability,” “good reason,” and “change of control” generally have the same meanings provided above under the severance agreements.

IPO Award Agreements

Under each NEO’s IPO performance award agreements, if such NEO’s employment is terminated without “cause” or if the NEO resigns for “good reason” and such termination of employment occurs prior to March 31, 2020, subject to the NEO’s execution and non-revocation of a release, (i) all unearned performance units that would have become earned in the performance period that includes the date of such termination of employment (based on year-to-date annualized performance for such performance period) will become earned as of the date of such termination of employment and (ii) the NEO will also be entitled to receive a lump sum cash “true up” payment with respect to each such earned performance unit equal to the cumulative amount of cash distributions that would have been paid to the NEO by us in respect of a common unit if the NEO had held a common unit during the period commencing on the date of grant of the performance units and ending on the date of the NEO’s termination of employment. If a NEO’s employment is terminated as a result of the NEO’s “disability” or death and such termination of employment occurs prior to March 31, 2020, (x) all unearned performance units that would have become earned in the performance period that includes the date of such termination (determined based on actual performance for such performance period) will become earned as of the date on which the compensation committee of the Board determines our adjusted operating surplus (and, if applicable, whether the subordination period has expired) for such performance period; and (y) with respect to each unearned performance unit, if any, that becomes earned pursuant to the preceding clause (x), the NEO will receive the true up payment described in clause (ii) of the prior sentence.

In addition, pursuant to Messrs. Carroll and Dorn’s IPO restricted unit award agreements, if either NEO’s employment is terminated without “cause” or if the NEO resigns for “good reason,” subject to the NEO’s compliance with a release requirement, a pro-rated portion of the NEO’s unvested common units will become vested as of such termination so long as the NEO has remained continuously employed between the date of grant through the date of such termination of employment; provided that if such termination of employment occurs within 24 months following a “change of control” or such termination occurs as a result of the NEO’s “disability” or death, all of the NEO’s unvested common units will become vested as of such termination.

For purposes of the IPO award agreements for both the performance units and the restricted units described above, “cause,” “good reason,” “change of control” and “disability” generally have the same meanings provided above under the severance agreements.

Director Compensation

Generally

Officers or employees of BSNRMC who also serve as directors of the General Partner will not receive additional compensation for such service. Each director of the General Partner who is not an officer or employee of BSNRMC receives the following cash compensation:

• an annual base retainer fee of $75,000 per year;

• an additional retainer of $20,000 per year if such director serves as the chairperson of the audit committee;

• an additional retainer of $15,000 per year if such director serves as the chairperson of the compensation committee; and

• an additional retainer of $10,000 per year if such director serves as the chairperson of any other committee.

25

In addition to cash compensation, our non-employee directors receive annual equity-based compensation under the LTIP consisting of fully vested common units. Such awards have an aggregate grant date value equal to $175,000 and will be subject to the terms and conditions of the LTIP and the award agreements pursuant to which such awards are granted. In the year in which a new non-employee director is elected to the Board for the first time, such director will also receive a one-time award under the LTIP with a grant date value equal to $100,000, subject to the terms and conditions of the LTIP and the award agreement pursuant to which such award is granted.

All retainers are paid in cash on a quarterly basis in arrears, subject to a non-employee director’s election to instead receive such retainers in the form of fully vested common units. Our non-employee directors do not receive any meeting fees, but each director is reimbursed for (i) travel and miscellaneous expenses to attend meetings and activities of the Board or its committees and (ii) travel and miscellaneous expenses related to participation in general education and orientation programs for directors.

IPO Awards

In connection with the IPO in May 2015, the Board granted awards under the LTIP to the non-employee directors of the General Partner consisting, in the aggregate, of approximately 60,000 common units under the LTIP. These awards represented a one-time $100,000 award subject to the terms and conditions of the LTIP and the award agreement that we entered into with the applicable non-employee director of the General Partner.

PROPOSAL 2—RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

General

The audit committee of the Board of the General Partner has appointed Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2016. BDO USA, LLP (“BDO”) served as our independent registered public accounting firm for the year ended December 31, 2015.

Representatives of Ernst & Young LLP and BDO are expected to be present at the Annual Meeting and will have the opportunity to make a statement should they choose to do so. They will also be available to respond to appropriate questions and inquiries from unitholders.

Unitholder ratification of the selection of Ernst & Young LLP as our independent registered public accounting firm is not required by the Partnership Agreement or otherwise. We have submitted ratification to a vote of the unitholders because we believe it is consistent with best practices in corporate governance to do so. If the unitholders fail to ratify the selection, the audit committee will reconsider the retention of that firm, but may retain such independent registered public accounting firm regardless. Even if the selection is ratified, the audit committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the audit committee determines that such a change would be in the best interests of us and our unitholders.

THE BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE RATIFICATION OF ERNST & YOUNG LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2016.

Changes in our Independent Registered Public Accounting Firm

On December 1, 2014, the Texas based practice of UHY LLP (“UHY”) was acquired by BDO.

On January 13, 2015, the audit committee of BSNR’s board of managers, the former general partner of our predecessor, approved the dismissal of UHY as our independent registered public accounting firm, effective immediately.

UHY’s report on our consolidated financial statements for the fiscal year ended December 31, 2013 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the year ended December 31, 2013 and in the subsequent interim period through January 13, 2015, there were (i) no disagreements between us and UHY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of UHY, would have caused UHY to make reference to the subject matter of the disagreement in its report on the consolidated financial statements for such year and (ii) no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

On January 13, 2015, the audit committee of BSNR’s board of managers engaged BDO as our independent registered public accounting firm.

During the year ended December 31, 2013 and the subsequent interim period through January 13, 2015, neither us nor anyone on our behalf consulted with BDO regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, and neither a written report nor oral advice was provided to us that BDO concluded was an important factor considered by us in reaching a decision as to the accounting, auditing, or financial reporting

29

issue or (ii) any matter that was either the subject of a “disagreement” (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

On March 15, 2016, the audit committee of the Board approved the dismissal of BDO as our independent registered public accounting firm. On March 15, 2016, the audit committee notified BDO of its dismissal effective immediately.

BDO’s reports on our consolidated financial statements for the fiscal years ended December 31, 2015 and 2014 did not contain an adverse opinion or a disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the two most recent fiscal years ended December 31, 2015 and 2014 and in the subsequent interim period through March 15, 2016, there were (i) no disagreements between us and BDO on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreement, if not resolved to the satisfaction of BDO, would have caused BDO to make reference to the subject matter of the disagreement in its reports on the consolidated financial statements for such years and (ii) no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).

On March 15, 2016, the audit committee of the Board approved the engagement of Ernst & Young LLP as our independent registered public accounting firm. Ernst & Young LLP was formally engaged on March 20, 2016.

During our two most recent fiscal years ended December 31, 2015 and 2014 and the subsequent interim period through March 15, 2016, neither us nor anyone on our behalf consulted with Ernst & Young LLP regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on our financial statements, and neither a written report nor oral advice was provided to us that Ernst & Young LLP concluded was an important factor considered by us in reaching a decision as to the accounting, auditing, or financial reporting issue or (ii) any matter that was either the subject of a “disagreement” (as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a “reportable event” (as that term is defined in Item 304(a)(1)(v) of Regulation S-K).
