 (i) Benjamin W. Hulburt, for so long as he serves as President and Chief Executive
Officer of the Company; 
 (ii) Christopher K. Hulburt, for so long as he serves as the Executive Vice President, Secretary
and General Counsel of the Company; and 
 (iii) Up to five persons designated by the EnCap Funds (the “EnCap
Directors”); provided, that the number of members that the EnCap Funds shall have the right to designate shall not exceed the product of the total number of current seats on the Board multiplied by the percentage of outstanding
shares of Common Stock then Beneficially Owned by the EnCap Entities, rounded to the nearest whole number. The “percentage of outstanding shares of Common Stock then Beneficially Owned by the EnCap Entities,” as such phrase is used in the
preceding sentence, shall be deemed to not 

  
 3 








 
exceed the lowest percentage of outstanding shares of Common Stock Beneficially Owned by the EnCap Entities as of any date following the date of this Agreement. In the event that the number of
members of the Board the EnCap Funds have the right to designate pursuant to this Section 2.1(a) shall be less than the current number of sitting board members designated by the EnCap Funds, any such excess sitting board member shall
tender his or her resignation to the Board. The EnCap Funds hereby initially designate D. Martin Phillips, Robert L. Zorich, Douglas E. Swanson, Jr. and Mark E. Burroughs, Jr. to serve as their director designees pursuant to this
Section 2.1(a)(iii). 
 (b) The Company and the Principal Stockholders shall take all Necessary Action to cause
Benjamin W. Hulburt to be elected Chairman of the Board. 
 (c) So long as the EnCap Entities Beneficially Own at least 50%
or more of the outstanding shares of Common Stock, unless the EnCap Funds elect otherwise, the Company and the Principal Stockholders shall take all Necessary Action to cause at least one EnCap Director (as is selected by the EnCap Funds from among
the current EnCap Directors) to be a member of each committee of the Board (subject to any requirements imposed by law or by the rules of any national securities exchange on which the Common Stock may be listed or traded). 

(d) So long as the EnCap Funds are entitled to designate one or more individuals to serve on the Board pursuant to
Section 2.1(a)(iii), the EnCap Funds shall have the right to remove such person (with or without cause), from time to time and at any time, from the Board, exercisable upon written notice to the Company and the Principal Stockholders,
and the Company and the Principal Stockholders shall take all Necessary Action to cause such removal. 
 (e) In connection
with the required resignation of any director designated by the EnCap Funds pursuant to this Section 2.1, such director may tender his resignation in advance of the date on which such resignation is required pursuant to this
Section 2.1 and the Board shall have the right to decline to accept such resignation, in which case such director shall continue to serve on the Board until the earlier of his subsequent resignation, death, disability or removal.
Notwithstanding the foregoing, any director designated by the EnCap Funds may elect to have his resignation be effective immediately upon tender. 

(f) In the event that a vacancy is created on the Board at any time by the death, disability, resignation or removal of a
director designated by the EnCap Funds, the EnCap Funds shall be entitled to designate an individual to fill the vacancy created by such death, disability, resignation or removal so long as the total number of persons that will serve on the Board as

Company and the Principal Stockholders shall take all Necessary Action to cause such replacement designee to become a member of the Board. 

(g) In the event the size of the Board is increased or decreased at any time, the number of directors of the Board subject to
designation by the EnCap Funds pursuant to Section 2.1(a)(iii) following such increase or decrease shall equal the product of the total number of seats on the increased or decreased Board multiplied by the percentage of seats on the
Board subject to the EnCap Funds’ designation rights pursuant to Section 2.1(a)(iii) immediately prior to such increase or decrease, rounded to the nearest whole number.

 2.2 Other Matters Subject to Stockholder Vote. Subject to Section 2.1, each
Principal Stockholder shall be entitled to instruct Eclipse Holdings to vote, in such Principal Stockholder’s sole discretion, the number of shares of Common Stock held by Eclipse Holdings as of the applicable voting record date that such
Principal Stockholder would receive pursuant to the terms of the limited partnership agreement of Eclipse Holdings following the complete distribution on such record date of the shares of Common Stock held by Eclipse Holdings on such record date.
Subject to Section 2.1, following any actual distribution of shares of Common Stock by Eclipse Holdings, each Principal Stockholder shall be entitled to vote such distributed shares of Common Stock in such Principal Stockholder’s
sole discretion. 
 2.3 Certain Restrictions. No Principal Stockholder shall 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 or Equity Securities if and to the extent the terms thereof conflict with the provisions of this Agreement (whether or not such proxy, voting trust,
agreement or arrangements are with other Principal Stockholders, holders of shares of Common Stock or Equity Securities that are not parties to this Agreement or otherwise). Each Principal Stockholder agrees to cause a transferee of its shares of
Common Stock that is an Affiliate of such Principal Stockholder to become a party to this Agreement. Following such transfer, such transferee shall be considered a Principal Stockholder. 

2.4 Reimbursement of Expenses. The Company shall reimburse each director designated pursuant to Section 2.1 for all
reasonable and documented out-of-pocket expenses incurred in connection with such director’s participation in the meetings of the Board or any committee of the Board, including all reasonable and documented travel, lodging and meal expenses.

 2.5 D&O Insurance. The Company shall use its best efforts to maintain in effect at all times directors and officers indemnity
insurance coverage reasonably satisfactory to the Board.

closing of the IPO does not occur, the provisions of this Agreement shall be without any force or effect. 
 3.2 Termination. This
Agreement shall terminate upon the earlier to occur of (a) such time as none of the Principal Stockholders Beneficially Own any shares of Common Stock, (b) such time as the EnCap Funds are no longer entitled to designate members of the
board of directors pursuant to Section 2.1, and (c) the delivery of written notice to the Company by all of the Principal Stockholders, requesting the termination of this Agreement. Further, at such time as a particular Principal
Stockholder no longer Beneficially Owns any shares of Common Stock, all rights and obligations of such Principal Stockholder under this Agreement shall terminate.
