The Investor shall also provide to the Company, upon reasonable request from the Company and in connection with providing the Required Information, evidence reasonably satisfactory to the Company that the Investor Group collectively Beneficially Own the number of shares of Common Stock that would be required to designate the Investor Director pursuant to this Section 3.1(b) then serving on the Board or then being designated to the Board in connection with an Election Meeting, as applicable.

4

(c) From and after the Closing Date until the Board Designation Expiration Date, the Company shall take all Necessary Actions to cause the Board to include the Investor Director entitled to be designated by the Investor pursuant to Section 3.1(b) and otherwise to reflect the Board composition contemplated by Section 3.1, including the following: (i) at each Election Meeting, include (x) the Investor Director entitled to be designated by the Investor pursuant to Section 3.1(b) in the slate of nominees recommended by the Board to the Company’s stockholders for election as directors, (ii) to solicit proxies in order to obtain stockholder approval of the election of the Investor Director, including causing officers of the Company who hold proxies (unless otherwise directed by the Company stockholder submitting such proxy) to vote such proxies in favor of the election of such Investor Director and (iii) to cause the Investor Director to be elected to the Board, including recommending that the Company’s stockholders vote in favor of the Investor Director in any proxy statement used by the Company to solicit the vote of its stockholders in connection with each Election Meeting.

The Investor Director shall be entitled to the same expense reimbursement and advancement, exculpation and indemnification in connection with his or her role as a director as the other members of the Board, as well as reimbursement for documented, reasonable out-of-pocket expenses incurred in attending meetings of the Board or any committee of the Board of which the Investor Director is a member, if any, in each case to the same extent as the other members of the Board. The Investor Director shall be also entitled to any retainer, equity compensation or other fees or compensation paid to the non-employee directors of the Company for their services as a director, including any service on any committee of the Board.

Section 3.4 Selection of the Investor Director; Committees.

(a) The Investor Director’s service as a member of the Board must be reasonably acceptable to the Governance Committee. The parties hereto agree that the person listed on Exhibit A to this Agreement is qualified for service pursuant to the foregoing sentence. Subject to applicable Law and stock exchange rules, until the Board Designation Expiration Date, the Investor Director shall be appointed to serve on the Governance Committee, subject to any limitations imposed by Law or stock exchange rules (including with respect to director independence requirements).

(b) Notwithstanding anything to the contrary herein, the Investor shall not be entitled to designate any Investor Director pursuant to Section 3.1(a) to the Board if the Board or a committee thereof reasonably determines that (i) the election of such Investor Director to the Board would cause the Company to not be in compliance with applicable Law or (ii) such Investor Director has been involved in any of the events that would be required to be disclosed in a registration statement on Form S-1 pursuant to Item 401(f)(2)-(8) of Regulation S-K under the Securities Act of 1933 or is subject to any order, decree or judgment of any Governmental Entity prohibiting service as a director of any public company. In any such case described in clauses (i) or (ii) of the immediately preceding sentence, the Investor shall withdraw the designation of such proposed Investor Director, and, subject to the requirements of this Section 3.4(b) be permitted to designate a replacement therefor (which replacement Investor Director will also be subject to the requirements of this Section 3.4(b)). The Company hereby agrees that the Investor Director listed on Exhibit A to this Agreement would not be prohibited from serving on the Board pursuant to clause (i) of the first sentence of this Section 3.4(b).

(c) Subject to Section 3.7, the Board may impose as a condition to the Investor Director serving on the Board that such Investor Director agree to, and be subject to, each Subject Policy. For the avoidance of doubt, no Subject Policy shall modify any of the rights and obligations of the parties to this Agreement, the Registration Rights Agreement between the parties dated as of the date hereof, the Merger Agreement or any other agreement entered into between the parties in connection with the transactions contemplated by the Merger Agreement.

Section 3.5 Lock-up. The Investor shall not, without the prior written consent of the Company, during the period commencing on the Closing Date and continuing for one hundred and eighty (180) days after the Closing Date (the “Lock-up Period”), (a) offer, pledge, sell, contract to sell, grant any option, right or warrant to purchase, give, assign, hypothecate, pledge, encumber, grant a security interest in, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise transfer or dispose of (including through any hedging or other similar transaction) any economic, voting or other rights in or to the Issued Shares, or otherwise transfer or dispose of, directly or indirectly, or (b) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Issued Shares (any such transaction described in clause (a) or (b) above, a “Transfer”). Notwithstanding the foregoing, the restrictions set forth in this Section 3.5 shall not apply to (i) Transfers involving in the aggregate no more than 26,326,096 shares of Common Stock (as appropriately adjusted for any stock split, stock dividend or similar transaction), (ii) Transfers to Permitted Transferees; provided, however, that if such Permitted Transferee is EnCap or any of its Controlled Affiliates, EnCap or such Controlled Affiliate must

6

agree in an executed written agreement (a copy of which will be delivered to the Company) for the benefit of the Company to be bound by the terms of this Section 3.5 prior to such Transfer or distribution, as applicable, and that any Permitted Transferee that is an Affiliate of EnCap and does not otherwise qualify as a Permitted Transferee shall also agree that such Person shall Transfer such shares of Common Stock back to EnCap if, during the Lock-Up Period, such Person ceases to be an Affiliate of EnCap, or (iii) any Transfers made in connection with any tender offer, exchange offer, merger, consolidation or other similar transaction approved or recommended by the Board or a committee thereof. Notwithstanding the foregoing, EnCap shall not be entitled to distribute shares of Common Stock to its limited partners during the Lock-Up Period. In connection with any Transfer to a Permitted Transferee, the Company agrees to not take any action that would cause such Transfer to be subject to requirements imposed by any “fair price,” “moratorium,” “control share acquisition,” “business combination” or any other anti-takeover statute or similar statute enacted under applicable Law (“Takeover Laws”), and, at the request of the Investor, will take all reasonable steps within its control to exempt (or ensure the continued exemption of) the Transfer from the Takeover Laws of any state that purport to apply to such transaction.

Section 3.6 Waiver of Corporate Opportunities. It is hereby acknowledged that members of the Investor Group participate in, and own and will own substantial equity interests in other entities (existing and future) that participate in, the energy industry (“Portfolio Companies”) and may make investments and enter into advisory service agreements and other agreements from time to time with those Portfolio Companies. Any individual who serves as the Investor Director may also serve as an employee, partner, officer, director, or member of the Investor Group or Portfolio Companies and, at any given time, members of the Investor Group or Portfolio Companies may be in direct or indirect competition with the Company and/or its subsidiaries. The Company waives, to the maximum extent permitted by Law, the application of the doctrine of corporate opportunity (or any analogous doctrine) with respect to the Investor Group or Portfolio Companies or the Investor Director. As a result of such waiver, no member of the Investor Group or Portfolio Companies, nor the Investor Director, shall have any obligation to refrain from: (A) engaging in or managing the same or similar activities or lines of business as the Company or any of its subsidiaries or developing or marketing any products or services that compete (directly or indirectly) with those of the Company or any of its subsidiaries; (B) acquiring assets in the same or similar areas of operation and lines of business of the Company; (C) investing in, owning or disposing of any (public or private) interest in any Person engaged in the same or similar activities or lines of business as, or otherwise in competition with, the Company or any of its subsidiaries (including any member of the Investor Group, a “Competing Person”); (D) developing a business relationship with any Competing Person; or (E) entering into any agreement to provide any service(s) to any Competing Person or acting as an officer, director, member, manager or advisor to, or other principal of, any Competing Person, regardless (in the case of each of clauses (A) through (E)) of whether such activities are in direct or indirect competition with the business or activities of the Company or any of its subsidiaries (the activities described in clauses (A) through (D) are referred to herein as “Specified Activities”). To the fullest extent permitted by Law, the Company hereby renounces (for itself and on behalf of its subsidiaries) any interest or expectancy in, or in being notified of or offered an opportunity to participate in, any Specified Activity that may be presented to or become known to any member of the Investor Group or Portfolio Companies or the Investor Director. Nothing in this Section 3.5 shall be construed to limit or waive any right of the Company or any of its subsidiaries pursuant to any express written agreement between the Company and/or one or more of its subsidiaries, on the one hand, and any member of the Investor Group, any Portfolio Company, or any of their respective employees, partners, officers, directors or members, on the other hand.

Section 3.7 Amendment to Organizational Documents. The Company shall not amend, or propose to amend, the Organizational Documents in any manner that is inconsistent with or would nullify or supersede any of the terms of this Agreement or would prevent any party hereto from complying with its obligations hereunder unless such proposed amendment is approved by the Investor.

Section 5.9 Assignment. Neither this Agreement nor any of the rights or obligations hereunder shall be assigned by any of the parties hereto without the prior written consent of the other parties; provided, however, that the Investor may assign any of its rights hereunder to any of its Affiliates to the extent such Affiliate is Transferred Common Stock not in violation of the terms of this Agreement and provided any such Affiliate execute a joinder to this Agreement. Subject to the preceding sentence, this Agreement will be binding upon, inure to the benefit of and be enforceable by the parties and their respective successors and assigns.

Section 5.10 Confidentiality. Each of the Investor and EnCap shall hold, and cause its Affiliates and its and their respective directors, managers, officers, employees, agents, consultants, auditors, attorneys, financial advisors, financing sources and other consultants and advisors (“Representatives”) to hold, in strict confidence, unless disclosure to a regulatory authority is necessary in connection with any necessary regulatory approval, examination or inspection or unless disclosure is required by judicial or administrative process or by other requirement of law or the applicable requirements of any regulatory agency or relevant stock exchange (in which case, other than in connection with a disclosure in connection with a routine audit or examination by, or document request from, a regulatory or self-regulatory authority, bank examiner or auditor, the party disclosing such information shall provide the other party with prior written notice of such permitted disclosure), all nonpublic records, books, contracts, instruments, computer data and other data and information (collectively, “Information”) concerning the Company, East or any of their respective subsidiaries furnished to it or the Investor Director by or on behalf of the Company, East or any of their respective subsidiaries (except to the extent that such information can be shown by the party receiving such Information to have been (a) previously known by such party from other sources; provided that such source was not known by such party to be bound by a contractual, legal or fiduciary obligation of confidentiality to the other party, (b) in the public domain through no violation of this Section 5.10 by such party or (c) later lawfully acquired from other sources by the party to which it was furnished), and no such party shall release or disclose such Information to any other person, except its Representatives (excluding, for the avoidance of doubt, any Portfolio Company, unless such Portfolio Company enters into a joinder agreement with the Company), or use such Information other than in connection with evaluating and taking actions with respect to such Person’s ownership interest in the Company. The Company acknowledges and agrees that the Investor and EnCap may, in the ordinary course of their respective businesses, evaluate investments in the energy industry and that they are actively seeking to invest in energy related projects in a variety of areas, including the provision of fresh water and disposal of produced water in connection with oil and gas exploration and development operations. The Company understands that the Investor, EnCap and the Investor Director will retain certain mental impressions of Information, which are indistinguishable from generalized industry knowledge. Accordingly, the Company agrees that, subject to the terms of this Agreement, the Investor, EnCap

11

and the Investor Director are not precluded from pursuing investments solely because of such retained mental impressions. Notwithstanding any provision of this Agreement to the contrary, no provision of this Agreement shall apply to any action taken independently by any Portfolio Company so long as the Investor or EnCap has not provided such Portfolio Company with any Information. For purposes of clarification, no such Portfolio Company shall be deemed to have been provided with Information solely as a result of the Investor, EnCap, any Investor Director or any Representative (whether such Person has been provided with or has knowledge of Information) serving on the board of such Portfolio Company (provided that such board member does not use Information in connection with the business of such Portfolio Company).
