 ARTICLE II 

GOVERNANCE MATTERS 

Section 2.1 Designees. 

(a) The Company and the Principal Stockholders shall take all Necessary Action to cause the Board to include members as follows: 

(i) If the Principal Stockholders and their respective Affiliates collectively Beneficially Own at least 50% of the outstanding
shares of Common Stock, up to three nominees designated by WildHorse Holdings and up to three nominees designated by Esquisto Holdings (each, an “Appointing Principal Stockholder” and collectively, the “Appointing
Principal Stockholders”); 
 (ii) If the Principal Stockholders and their respective Affiliates collectively
Beneficially Own less than 50% but at least 35% of the outstanding shares of Common Stock, two nominees designated by WildHorse Holdings and two nominees designated by Esquisto Holdings; 

(iii) If the Principal Stockholders and their respective Affiliates collectively Beneficially Own less than 35% but at least
15% of the outstanding shares of Common Stock, one nominee designated by WildHorse Holdings, one nominee designated by Esquisto Holdings and one nominee designated by a mutual agreement between the Appointing Principal Stockholders; and 

(iv) If the Principal Stockholders and their respective Affiliates collectively Beneficially Own less than 15% but at least 5%
of the outstanding shares of Common Stock, one nominee designated by WildHorse Holdings and one designated by Esquisto Holdings. 
 If the
Principal Stockholders and their respective Affiliates collectively Beneficially Own less than 5% of the outstanding shares of Common Stock, the Appointing Principal Stockholders shall not be entitled to designate a nominee. 

For the avoidance of doubt, the rights granted to the Appointing Principal Stockholders to designate members of the Board are additive to, and
not intended to limit in any way, the rights that the Principal Stockholders or any of their respective Affiliates may have to nominate, elect or remove directors under the Company’s certificate of incorporation, bylaws or the Delaware General
Corporation Law. 
 The Company agrees, to the fullest extent permitted by applicable law (including with respect to any applicable
fiduciary duties under Delaware law), that taking all necessary corporate action to effectuate the above shall include (A) including the persons designated pursuant to this Section 2.1(a) in the slate of nominees recommended by the
Board for election at any meeting of stockholders called for the purpose of electing directors, (B) nominating and recommending each such individual to be elected as a director as provided herein, and (C) soliciting proxies or consents in
favor thereof. The Company is entitled to identify such individual as a WildHorse Holdings Director or Esquisto Holdings Director, as applicable, pursuant to this Agreement.

(i) the directors designated by the Principal Stockholders pursuant to this Section 2.1 (the “Principal Stockholder Directors”) shall be in different classes of directors to the extent practicable and
(ii) the Appointing Principal Stockholders (acting by mutual agreement) shall be permitted to designate the class or classes to which each Principal Stockholder Director shall be allocated. 

(c) So long as the Principal Stockholders and their respective Affiliates collectively Beneficially Own 15% or more of the outstanding shares
of Common Stock, the Appointing Principal Stockholders by mutual agreement between them will have the right to cause the Board to include at least one Principal Stockholder Director on each committee of the Board as designated by the Appointing
Principal Stockholders (subject to any independence requirement imposed by applicable law or by the applicable rules of any national securities exchange on which the Common Stock may be listed or traded). 

(d) So long as an Appointing Principal Stockholder is entitled to designate one or more nominees pursuant to Section 2.1(a), such
Appointing Principal Stockholder shall have the right to remove any Principal Stockholder Director (with or without cause) appointed by such Principal Stockholder, from time to time and at any time, from the Board, exercisable upon written notice to
the Company, and the Company shall take all Necessary Action to cause such removal; provided that the agreement of both Appointing Principal Stockholders shall be required to remove a Principal Stockholder Director appointed by the mutual agreement
of the Appointing Principal Stockholders pursuant to Section 2.1(a)(ii) 
 (e) In the event that a vacancy is created on the Board at
any time by the death, disability, resignation or removal (whether by the Appointing Principal Stockholders or otherwise in accordance with the Company’s certificate of incorporation and bylaws, as either may be amended or restated from time to
time) of a Principal Stockholder Director, the Appointing Principal Stockholder entitled to appoint such Principal Stockholder Director shall be entitled to designate an individual to fill the vacancy so long as the total number of persons that will
serve on the Board as designees of such Appointing Principal Stockholder immediately following the filling of such vacancy will not exceed the total number of persons such Appointing Principal Stockholder is entitled to designate pursuant to
Section 2.1(a) on the date of such replacement designation; provided that the consent of both Appointing Principal Stockholders shall be required to designate the individual to fill any vacancy resulting from the death, disability,
resignation or removal of the Principal Stockholder Director appointed by the mutual agreement of the Appointing Principal Stockholders pursuant to Section 2.1(a)(ii). The Company and the Principal Stockholders shall take all Necessary
Action to cause such replacement designee to become a member of the Board. 
 Section 2.3 Restrictions on Other Agreements. No
Principal Stockholder shall, directly or indirectly, grant any proxy or enter into or agree to be bound by any voting trust, agreement or arrangement of any kind with respect to its shares of Common Stock if and to the extent the terms thereof
conflict with the provisions of this Agreement (whether or not such proxy, voting trust, agreement or agreements are with other Principal Stockholders, holders of shares of Common Stock that are not parties to this Agreement or otherwise).
