Agreement

Section 1.Board Designation Rights.

(a)Each of the Sanchez Entities shall take all actions necessary or advisable to cause (i) two directors serving on the Board to be designated by the Purchaser, in its sole discretion (each, a “Purchaser Designated Director”), at all times from the date of this Agreement until the occurrence of (A) the First Designation Right Termination Event (as defined below), at which time the right of the Purchaser under this Agreement to designate one member of such Board shall terminate and (B) the Second Designation Right Termination Event (as defined below), at which time the right of the Purchaser under this Agreement to designate one member of such Board shall terminate and (ii) three independent directors serving on the Board to be designated by the Purchaser, in its sole discretion (each director designated by the Purchaser pursuant to this Section 1(a), a “Purchaser Designated Director”), at all times during the Redemption Designation Period (as defined below); provided, however, that each such Purchaser Designated Director shall (1) in the reasonable judgment of the General Partner, have the requisite skill and experience to serve as a director of a public company, (2) not be prohibited or disqualified from serving as a director of the General Partner by any rule or regulation of the Commission, the National Securities Exchange (as defined in the Partnership Agreement) on which the Common Units are listed or applicable Law and (3) otherwise be reasonably acceptable to the General Partner.  Prior to a Designation Right Termination Event (as defined below) or during the Redemption Designation Period, any Purchaser Designated Director may be removed by the Purchaser at any time and may be removed by a majority of the other directors then serving on the Board for “cause” (as defined below); and any vacancy in such positions shall be filled solely by the Purchaser.  As used herein, “cause” means that a Purchaser Designated Director (w) is prohibited from serving as a director of the General Partner under any rule or regulation of the Commission or the National Securities Exchange (as defined in the Partnership Agreement) on which the Common Units are listed; (x) has been convicted of a felony or misdemeanor involving moral turpitude; (y) has engaged in acts or omissions against the General Partner or the Partnership constituting dishonesty, breach of fiduciary obligation, or intentional wrongdoing or misfeasance; or (z) has acted intentionally or in bad faith in a manner that results in a material detriment to the assets, business or prospects of the General Partner or the Partnership.  None of the Sanchez Entities shall take any action which would, or would be reasonably likely to, adversely affect the Purchaser’s right to appoint Purchaser Designated Directors; provided, however, that the Sanchez Entities shall not be prohibited from taking such action that the Board determines is necessary to comply with any rule or regulation of the Commission or the National Securities Exchange (as defined in the Partnership Agreement) on which the Common Units are listed or applicable Law. 

(b)Prior to the occurrence of a Designation Right Termination Event, the General Partner shall invite the Purchaser Designated Directors to attend all meetings of each committee of the Board (other than the Audit Committee, the Conflicts Committee, any pricing committee established for an offering of securities by the Partnership and any committee established to deal with conflicts with the Purchaser or its Affiliates) in a nonvoting observer capacity and, in this respect, shall give the Purchaser Designated Directors copies of all notices, minutes, consents and other materials that it provides to the other members of such committee; provided, however, that during the Redemption Designation Period, the Purchaser Designated Directors designated pursuant to clause (ii) of Section 1(a) shall serve on all committees of the Board in a voting capacity.

(c)Commencing as of the Closing, the Purchaser Designated Directors are Jack Howell and Luke Taylor.

(d)Any action by the Purchaser to designate, remove or replace a Purchaser Designated Director shall be evidenced in writing and furnished to the General Partner no later than one Business Day after the taking of such action, shall include a statement that the action has been approved by the requisite vote of the Purchaser and shall be executed by or on behalf of the Purchaser.  The Purchaser agrees to cause each Purchaser Designated Director to timely provide the Partnership with accurate and complete information relating to the Purchaser and such Purchaser Designated Director that may be required to be disclosed by the Partnership under the Exchange Act.  In addition, at the Partnership’s reasonable request, the Purchaser shall cause each Purchaser Designated Director to complete and execute the Partnership’s standard director and officer questionnaire prior to being admitted to the Board.

(e)Upon the occurrence of a Designation Right Termination Event or the end of the Redemption Designation Period, as applicable, the right of the Purchaser to designate a Purchaser Designated Director shall terminate and the Purchaser Designated Director then serving as such a member of the Board, promptly upon (and in any event within two Business Days following) receipt of a request from a majority of the other director(s) then serving on the Board or the owner(s) of a majority of the equity interests of the General Partner, shall resign as a member of the Board.  If the Purchaser Designated Director does not resign upon such request, then a majority of the other director(s) then serving on the Board or the owner(s) of a majority of the equity interests of the General Partner, may remove the Purchaser Designated Director as a member of the Board.

(f)For the purposes of this Agreement, the “First Designation Right Termination Event” shall occur on the date on which the Purchaser and its Affiliates hold fewer than 25% of the number of Class B Preferred Units initially issued to the Purchaser pursuant to the Purchase Agreement, as adjusted for any subdivisions, splits, reverse unit splits, reclassification, reorganization or other similar transaction by the Partnership affecting the Class B Preferred Units.  For the purposes of this Agreement, the “Second Designation Right Termination Event” shall occur on the date on which Purchaser and its Affiliates no longer hold any Class B Preferred Units.  Each of the First Designation Right Termination Event and the Second Designation Right Termination Event are referred to herein as a “Designation Right Termination Event.” For the purposes of this Agreement, the “Redemption Designation Period” shall commence on January 1, 2022 if any Class B Preferred Units remain outstanding on such date and shall continue until the date on which all Class B Preferred Units have been redeemed pursuant to the provisions of the Partnership Agreement or have been converted into Common Units.

Section 2.Limitation of Liability; Indemnification; Business Opportunities. 

(a)At all times while each Purchaser Designated Director is serving as a member of the Board, and following any such Purchaser Designated Director’s death, resignation, removal or other cessation as a director in such former Purchaser Designated Director’s capacity as a former director, such Purchaser Designated Director shall be entitled to (i) the same modification and restriction of traditional fiduciary duties, (ii) the same safe harbors for resolving conflicts of interest transactions and (iii) all rights to indemnification and exculpation, in each case, as are then made available to any other member of the Board.

(b)At all times while each Purchaser Designated Director is serving as a member of the Board, such Purchaser Designated Director, the Purchaser and their respective Affiliates may engage in, possess an interest in, or trade in the securities of, other business ventures of any nature or description, independently or with others, similar or dissimilar to the business of the Sanchez Entities, and the Sanchez Entities, the Board and their Affiliates shall have no rights by virtue of this Agreement or otherwise in and to such independent ventures or the income or profits derived therefrom, and the pursuit of any such venture, even if competitive with the business of the Sanchez Entities, shall not be deemed wrongful or improper.  None of the Purchaser Designated Directors, the Purchaser or their respective Affiliates shall be obligated to present any investment opportunity to the Sanchez Entities even if such opportunity is of a character that the Sanchez Entities or any of their respective Affiliates might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each of the Purchaser Designated Directors, the Purchaser and their respective Affiliates shall have the right to take for such Person’s own account (individually or as a partner, fiduciary or otherwise) or to recommend to others any such investment opportunity.  Notwithstanding the foregoing, the Purchaser shall cause each Purchaser Designated Director to maintain the confidentiality of all information and proceedings of the Board.

(c)The Sanchez Entities shall purchase and maintain (or reimburse each Purchaser Designated Director for the cost of) insurance (“D&O Insurance”), on behalf of such Purchaser Designated Director, in an amount and scope of coverage commensurate with that provided to an independent member of the Board, with respect to liabilities that may be asserted against, or expense that may be incurred by, such Purchaser Designated Director in connection with the Sanchez Entities’ activities or such Purchaser Designated Director’s activities on behalf of the Sanchez Entities, regardless of whether the Sanchez Entities would have the power to indemnify such Purchaser Designated Director against such liability under the provisions of the Partnership Agreement or the Limited Liability Company Agreement of the General Partner, as amended (the “GP LLC Agreement”).

(d)For the avoidance of doubt, each Purchaser Designated Director shall constitute an “Indemnitee,” as such term is defined under the Partnership Agreement and the GP LLC Agreement.
