This Voting Agreement (this “Agreement”), dated as of June 7, 2021, is entered into by and among Independence Energy LLC, a Delaware limited liability company (“Isla”), John C. Goff (“Goff”) and each other signatory hereto (each, together with Goff, a “Stockholder”). Isla and Stockholders are each sometimes referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, concurrently with the execution of this Agreement, the Company, Isla and certain Subsidiaries of Isla are entering into a Transaction Agreement (as the same may be amended from time to time, the “Transaction Agreement”), providing for, among other things, the merger (the “Merger”) of IE C Merger Sub Inc., a Texas corporation, and the Company pursuant to the terms and conditions of the Transaction Agreement;

WHEREAS, in order to induce Isla to enter into the Transaction Agreement, Stockholders are willing to make certain representations, warranties, covenants, and agreements as set forth in this Agreement with respect to the 48,406,233 shares of common stock, par value $0.04 per share, of the Company (“Company Common Stock”) Beneficially Owned (as defined below) by Stockholders (the “Original Shares” and, together with any additional shares of Company Common Stock pursuant to Section 6 hereof, the “Shares”); and

WHEREAS, as a condition to their willingness to enter into the Transaction Agreement, Isla has required that Stockholders, and Stockholders have agreed to, execute and deliver this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants, and agreements set forth below and for other good and valuable consideration, the receipt, sufficiency, and adequacy of which are hereby acknowledged, the Parties hereto, intending to be legally bound, do hereby agree as follows:

For purposes of this Agreement, capitalized terms used and not otherwise defined herein shall have the respective meanings ascribed to such terms in the Transaction Agreement. When used in this Agreement, the following terms in all of their tenses, cases, and correlative forms shall have the meanings assigned to them in this Section 1.

(a)“Affiliate” means with respect to any Person, any other Person directly or indirectly, controlling, controlled by, or under common control with, such Person, through one or more intermediaries or otherwise; provided, however, that solely for purposes of this Agreement, notwithstanding anything to the contrary set forth herein, neither the Company nor any of its Subsidiaries shall be deemed to be a Subsidiary or Affiliate of any Stockholder; provided, further, that, for the avoidance of doubt, any member of any Stockholder shall be deemed an Affiliate such Stockholder; and provided, further, that an Affiliate of any Stockholder shall include any investment fund, vehicle or holding company of which such Stockholder or an affiliate thereof serves as the general partner, managing member or discretionary manager or advisor.

(b)“Beneficially Own” or “Beneficial Ownership” has the meaning assigned to such term in Rule 13d-3 under the Exchange Act, and a Person’s beneficial ownership of securities shall be calculated in accordance with the provisions of such rule (in each case, irrespective of whether or not such rule is actually applicable in such circumstance). For the avoidance of doubt, “Beneficially Own” and “Beneficial Ownership” shall also include record ownership of securities.

(c)“Beneficial Owner” shall mean the Person who Beneficially Owns the referenced securities.

Each Stockholder represents and warrants to Isla that:

(a)Ownership of Shares. Such Stockholder (i) is the Beneficial Owner of the portion of the Original Shares set forth on Annex A free and clear of any proxy, voting restriction, adverse claim, or other Encumbrances, other than those created by this Agreement or under applicable federal or state securities laws; and (ii) has the sole voting power over such Original Shares. Except as expressly provided by this Agreement, there are no options, warrants, or other rights, agreements, arrangements, or commitments of any character to which such Stockholder is a party relating to the pledge, disposition, or voting of any of such Original Shares and there are no voting trusts or voting agreements with respect to such Original Shares.

(b)Disclosure of All Shares Owned. Neither such Stockholder nor any of its Affiliates Beneficially Owns any shares of Company Common Stock other than the Original Shares.

(c)Power and Authority; Binding Agreement. Such Stockholder has full power and authority to enter into, execute, and deliver this Agreement and to perform fully such Stockholder’s obligations hereunder (including the proxy described in Section 3(b) below). This Agreement has been duly and validly executed and delivered by such Stockholder and constitutes the legal, valid, and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms.

(d)No Conflict. The execution and delivery of this Agreement by such Stockholder does not, and the consummation of the transactions contemplated hereby and the compliance with the provisions hereof will not, conflict with or violate any Law applicable to such Stockholder or result in any breach of or violation of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration, or cancellation of, or result in the creation of any Encumbrance on any of the Shares pursuant to, any agreement or other instrument or obligation, including organizational documents binding upon such Stockholder or any of the Shares.

(e)No Consents. No Consent, order or declaration of any Governmental Entity or any other Person on the part of such Stockholder is required in connection with the valid execution and delivery of this Agreement.

(f)No Litigation. There is no Proceeding pending against, or, to the knowledge of such Stockholder, threatened against or affecting, such Stockholder that could reasonably be expected to materially impair or materially adversely affect the ability of such Stockholder to perform such Stockholder’s obligations hereunder or to consummate the transactions contemplated by this Agreement on a timely basis.

(a)Agreement to Vote and Approve. Each Stockholder irrevocably and unconditionally agrees during the term of this Agreement, at any annual or special meeting of the Company called with respect to the following matters, and at every adjournment or postponement thereof, and on every action or approval by written consent of the Company stockholders with respect to any of the following matters, to appear at any such meeting or otherwise cause the applicable Shares to be counted as present thereat

for purpose of establishing a quorum and vote or cause the holder of record to vote the Shares at such meeting (i) in favor of (1) adoption of the Transaction Agreement and approval of any other matters necessary for consummation of the Transactions, including the Merger and (2) any proposal to adjourn or postpone such meeting of stockholders of the Company to a later date if there are not sufficient votes to approve the Transactions, including the Merger; and (ii) against (1) any Company Competing Proposal or any of the transactions contemplated thereby, (2) any action, proposal, transaction, or agreement which could reasonably be expected to result in a breach of any covenant, representation or warranty, or any other obligation or agreement of the Company under the Transaction Agreement or of such Stockholder under this Agreement, and (3) any action, proposal, transaction, or agreement that could reasonably be expected to impede, interfere with, delay, discourage, adversely affect, or inhibit the timely consummation of the Transactions, including the Merger, or the fulfillment of the Isla Parties’ conditions under the Transaction Agreement or change in any manner the voting rights of any class of shares of the Company (including any amendments to the Company’s Organizational Documents). Any attempt by any Stockholder to vote, consent or express dissent with respect to (or otherwise to utilize the voting power of), any Shares in contravention of this Section 3(a) shall be null and void ab initio.

(b)Irrevocable Proxy. Each Stockholder hereby appoints Isla and any designee of Isla, and each of them individually, until the Expiration Time (at which time this proxy shall automatically be revoked), its proxies and attorneys-in-fact, with full power of substitution and resubstitution, to vote or consent during the term of this Agreement with respect to the Shares in accordance with Section 3(a). This proxy and power of attorney is given to secure the performance of the duties of such Stockholder under this Agreement. Each Stockholder shall take such further action or execute such other instruments as may be necessary to effectuate the intent of this proxy. This proxy and power of attorney granted by each Stockholder shall be irrevocable during the term of this Agreement, shall be deemed to be coupled with an interest sufficient in law to support an irrevocable proxy and shall revoke any and all prior proxies granted by such Stockholder with respect to the applicable Shares. The proxy and power of attorney granted hereunder shall terminate upon the termination of this Agreement.

Each Stockholder agrees that during the term of this Agreement such Stockholder will not, and will not permit any Affiliate to, deposit any of the Shares in a voting trust, grant any proxies with respect to the Shares, or subject any of the Shares to any arrangement with respect to the voting of the Shares other than agreements entered into with Isla.

Each Stockholder agrees that during the term of this Agreement, such Stockholder will not, directly or indirectly, transfer, sell, offer, exchange, assign, pledge, convey any legal or Beneficial Ownership interest in or otherwise dispose of (by merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by operation of Law or otherwise) or Encumber (“Transfer”) any of the Shares or enter into any contract, option or other agreement with respect to, or consent to, a Transfer of any of the Shares or such Stockholder’s voting or economic interest therein. This Section 5 shall not prohibit a Transfer of the Shares by any Stockholder to an Affiliate of such Stockholder; provided, that a Transfer referred to in this sentence shall be permitted only if, as a precondition to such Transfer, the transferee agrees in a writing, reasonably satisfactory in form and substance to Isla, to be bound by all of the terms of this Agreement. Any attempted Transfer of Shares or any interest therein in violation of this Section 5 shall, to the fullest extent permitted by Law, be null and void ab initio. If any involuntary Transfer of any of any Stockholder’s Shares shall occur, the transferee

(which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Shares subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement.

Each Stockholder agrees that any shares of Company Common Stock and any other shares of capital stock or other equity of the Company that such Stockholder purchases, acquires the voting power or otherwise acquires Beneficial Ownership of after the execution of this Agreement and prior to the Expiration Time shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof for all purposes of this Agreement, and such Stockholder shall promptly notify the Company of the existence of any such after-acquired Shares. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares or the like of the capital stock of the Company affecting the Shares, the terms of this Agreement shall apply to the resulting securities and such resulting securities shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares as of the date hereof for all purposes of this Agreement.

(a)Waiver of Appraisal and Dissenters’ Rights. To the fullest extent permitted by Law, each Stockholder hereby irrevocably and unconditionally waives, and agrees not to assert or perfect, any rights of appraisal (including under Section 10.354 of the Texas Business Organization Code) or rights to dissent in connection with the Merger that such Stockholder may have by virtue of ownership of such Stockholder’s Shares.

(b)Waiver of Certain Other Actions. Each Stockholder hereby agrees not to commence, join in, and agrees to take all actions necessary to opt out of any class in any class action with respect to, any claim, derivative or otherwise, against Isla, Merger Sub or the Company or any of their respective Affiliates and each of their successors or directors relating to the negotiation, execution or delivery of this Agreement or the Transaction Agreement or the consummation of the transactions contemplated hereby or thereby, including any claim (a) challenging the validity of, or seeking to enjoin the operation of, any provision of this Agreement or the Transaction Agreement (including any claim seeking to enjoin or delay the Closing) or (b) alleging a breach of any fiduciary duty of the Company Board in connection with the negotiation and entry into this Agreement, the Transaction Agreement or the transactions contemplated hereby or thereby, and hereby irrevocably waives any claim or rights whatsoever with respect to any of the foregoing.

This Agreement shall terminate upon the earliest to occur of (the “Expiration Time”): (a) the Effective Time; (b) the date on which the Transaction Agreement is terminated in accordance with its terms; and (c) the termination of this Agreement by mutual written consent of the Parties. Nothing in this Section 8 shall relieve or otherwise limit the liability of any Party for any intentional breach of this Agreement prior to such termination.

Subject to Section 10, each Stockholder shall not, and shall cause its Affiliates and its and their Representatives not to, directly or indirectly, take any of the actions set forth in Section 6.3(b) of the Transaction Agreement (without giving effect to any amendment or modification of such clauses after the

date hereof). Each Stockholder shall, and shall cause its Affiliates and its and their Representatives to, immediately cease, and cause to be terminated, any discussions or negotiations conducted before the date of this Agreement with any Person other than Isla with respect to any inquiry, proposal or offer that constitutes, or would reasonably be expected to lead to, a Company Competing Proposal. In addition, each Stockholder agrees to be subject to Section 6.3(c) of the Transaction Agreement (without giving effect to any amendment or modification of such clauses after the date hereof) as if such Stockholder were the “Company” thereunder. Notwithstanding the foregoing, to the extent the Company complies with its obligations under Section 6.3 of the Merger Agreement and participates in discussions or negotiations with a Person regarding a Company Competing Proposal, the Holder or any of such Holder’s controlled Affiliates and/or such Holder’s and such Holder’s Affiliates’ Representatives may engage in discussions or negotiations with such Person to the extent that the Company can act under Section 6.3 of the Merger Agreement.

Each Stockholder agrees, from time to time, and without additional consideration, to execute and deliver such additional proxies, documents and other instruments and to take all such further action as Isla may reasonably request to consummate and make effective the transactions contemplated by this Agreement and to not take or permit any of its Affiliates to take any action that would reasonably be likely to adversely affect or delay the ability to perform such Stockholder’s covenants and agreements under this Agreement.

The Parties agree that irreparable damage, for which monetary damages would not be an adequate remedy, would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached by the Parties. Prior to the Expiration Time, it is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, in each case in accordance with this Section 11, this being in addition to any other remedy to which they are entitled under the terms of this Agreement at Law or in equity. Each Party accordingly agrees not to raise any objections to the availability of the equitable remedy of specific performance to prevent or restrain breaches or threatened breaches of, or to enforce compliance with, the covenants and obligations of such party under this Agreement, all in accordance with the terms of this Section 11. Each Party further agrees that no other Party or any other Person shall be required to obtain, furnish or post any bond or similar instrument in connection with or as a condition to obtaining any remedy referred to in this Section 11, and each Party irrevocably waives any right it may have to require the obtaining, furnishing or posting of any such bond or similar instrument.

This Agreement (together with the Transaction Agreement, the Confidentiality Agreement and any other documents and instruments executed pursuant hereto) supersedes all prior agreements, written or oral, between the Parties hereto with respect to the subject matter hereof and contains the entire agreement between the Parties with respect to the subject matter hereof. This Agreement may not be

amended or supplemented, and no provisions hereof may be modified or waived, except by an instrument in writing signed by both of the Parties hereto. No waiver of any provisions hereof by either Party shall be deemed a waiver of any other provisions hereof by such Party, nor shall any such waiver be deemed a continuing waiver of any provision hereof by such Party.

At any time prior to the Effective Time, the Parties may, to the extent legally allowed:

(a)extend the time for the performance of any of the obligations or acts of the other Party hereunder;

(b)waive any inaccuracies in the representations and warranties of the other Party contained herein or in any document delivered pursuant hereto; or

(c)waive compliance with any of the agreements or conditions of the other Party contained herein;

provided, that, in each case, such waiver is made in writing and signed by the Party (or parties) against whom the waiver is to be effective.

Notwithstanding the foregoing, no failure or delay by Isla in exercising any right hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise of any other right hereunder. No agreement on the part of a Party to any such extension or waiver shall be valid unless set forth in an instrument in writing signed on behalf of such Party. No waiver by any of the Parties hereto of any default, misrepresentation or breach of representation, warranty, covenant or other agreement hereunder, whether intentional or not, shall be deemed to extend to any prior or subsequent default, misrepresentation or breach or affect in any way any rights arising by virtue of any prior or subsequent such occurrence.

All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given: (a) if delivered in person; (b) if transmitted by facsimile (but only upon confirmation of transmission by the transmitting equipment); (c) if transmitted by electronic mail (“e-mail”) (but only if confirmation of receipt of such e-mail is requested and received; provided, that each notice party shall use reasonable best efforts to confirm receipt of any such email correspondence promptly upon receipt of such request); or (d) if transmitted by national overnight courier. Such communications must be sent to the respective Parties at the following addresses (or at such other address for a Party as shall be specified in a notice given in accordance with this Section 15):
