(a)To the Knowledge of Buyer Parties, except for property sold or otherwise disposed of, impaired or abandoned in the ordinary course of business since the date of the Earthstone Reserve Report, Earthstone has good and defensible title to all oil and gas properties forming the basis for the reserves reflected in the Earthstone Reserve Report as attributable to interests owned or held by Earthstone free and clear of all Encumbrances, except for Encumbrances set forth in Section 3.9(a) of the Earthstone Disclosure Schedule and any other liens, charges, encumbrances, defects or irregularities that do not, individually or in the aggregate, materially detract from the value of or materially interfere with the use or ownership of such oil and gas properties. The oil and gas leases and other agreements that provide Earthstone with operating rights in the oil and gas properties reflected in the Earthstone Reserve Report are in full force and effect as to the oil and gas properties reflected in the Earthstone

Reserve Report, and the rentals, royalties and other payments due thereunder have been properly and timely paid and there is no existing default (or event that, with notice or lapse of time or both, would become a default) under any of such oil and gas leases or other agreements, except, in each case, as individually or in the aggregate has not had, and would not be reasonably likely to have or result in, a Material Adverse Effect on Earthstone. For purposes of this Section 3.9, “good and defensible title” means title that is free from reasonable doubt to the end that a prudent person engaged in the business of purchasing and owning, developing, and operating producing or non-producing oil and gas properties in the geographical areas in which they are located, with knowledge of all of the facts and their legal bearing, would be willing to accept, acting reasonably.

(b)To the Knowledge of Buyer Parties, all producing oil and gas wells included in the Earthstone Properties operated by Earthstone have been drilled, operated and produced in accordance in all material respects with reasonable, prudent oil and gas field practice and in compliance in all material respects with applicable oil and gas leases and applicable Law. All producing oil and gas wells and related material equipment are in an operable state of repair, adequate to maintain normal operations in accordance with past practices, ordinary wear and tear excepted.

(c)To the Knowledge of Buyer Parties, except as set forth on Section 3.9(c) of the Earthstone Disclosure Schedule, all proceeds from the sale of Hydrocarbons produced from the Earthstone Properties are being received by Earthstone in a timely manner and are not being held in suspense for any reason by any Person by whom proceeds are being paid except for immaterial amounts.

(d)To the Knowledge of Buyer Parties, except as would not, individually or in the aggregate, have a Material Adverse Effect on Earthstone, neither Earthstone (as to wells operated by Earthstone) nor an applicable operator (as to wells not operated by Earthstone), is in material breach of, or default under, any oil and gas lease, oil, gas, and mineral lease and sublease, royalty, overriding royalty, net profits interest, mineral fee interest, carried interest, interests under a concession, production sharing, risk service, technical service, service, or similar agreement that is, or constitutes an interest in, the Earthstone Properties.

Section 3.10Compliance With Laws.

Section 5.10Tax Matters.

(a)Tax Return Preparation; Refunds. All U.S. federal income Tax Returns for Taxes and Tax items relating to the operations, income or assets of Independence Management that is allocable to, and reportable as income of, Independence Management’s direct or indirect equityholders under applicable Law that are due after the Closing Date (the “Independence Responsible Returns”), shall be prepared and filed under the control of Independence, and Seller Parties and their direct or indirect equityholders shall be responsible for any Taxes required to be paid with respect thereto. Provided, however, EEH shall cause the preparation of the Independence Responsible Returns on behalf of Independence (and issue Schedule K-1s to Form 1065 to Seller Parties), and shall cause drafts of such Tax Returns to be

provided to Independence at least thirty (30) Business Days prior to the filing thereof for Independence’s prompt review, comment and approval, and EEH shall make such revisions to such Tax Returns as are reasonably requested by Independence in accordance with applicable Law. The Independence Responsible Returns shall be prepared consistent with past practice except as otherwise required by applicable Law, and shall be timely filed (or caused to be timely filed) with the appropriate Governmental Body. For the avoidance of doubt, (i) any Tax liabilities (other than liabilities for U.S. federal income Taxes) for any Pre-Closing Tax Period or Straddle Period shall be the responsibility of and shall be paid by EEH and its Affiliates, and (ii) any Tax refunds or credits in lieu of refunds (in each case, other than refunds or credits in lieu of refunds for U.S. federal income Taxes) for any Pre-Closing Tax Period or Straddle Period shall be for the benefit of EEH and its Affiliates. Other than Independence Responsible Returns, EEH shall control the preparation and filing of all other Tax Returns for Pre-Closing Tax Periods and Straddle Periods with respect to the Acquired Entities that have not yet been filed as of the Closing Date and shall pay any Taxes required to be paid thereon. For the avoidance of doubt, all U.S. federal income Tax Returns relating to the operations, income, assets or liquidation of Independence Manager shall be prepared and filed under the control of Independence, and Independence shall be responsible for any Taxes with respect thereto.

(b)Cooperation on Tax Returns and Tax Proceedings. EEH and Independence shall cooperate fully as and to the extent reasonably requested by another Party, in connection with the filing of Tax Returns and any Proceeding (each a “Tax Proceeding”) with respect to Taxes imposed on or with respect to the Acquired Entities and Independence Properties. Such cooperation shall include the retention and (upon another Party’s request) the provision of records and information which are reasonably relevant to any such Tax Return or Tax Proceeding and making employees available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Independence further agrees, upon request, to use commercially reasonable efforts to obtain any certificate or other document from any Governmental Body or any other Person as may be necessary to mitigate, reduce or eliminate any Tax that could be imposed on Buyer Parties or the Acquired Entities (including, but not limited to, with respect to the transactions contemplated hereby).

(c)Purchase Price Allocation. Within ninety (90) days following the Closing Date, EEH shall cause to be prepared and delivered to Independence a schedule allocating the Purchase Price (and all other amounts treated as consideration for federal income Tax purposes) attributable to the purchase of the Independence Interests of the Acquired Entities among the Independence Properties (the “Purchase Price Allocation”). The Purchase Price Allocation shall be reasonable and shall be prepared in accordance with Code Section 1060. The Purchase Price Allocation shall be deemed to be accepted by, and shall be conclusive and binding on, Seller Parties except to the extent that Independence shall have delivered, within thirty (30) days after the date on which the Purchase Price Allocation is delivered to Independence, a written notice to EEH stating each and every item to which Independence takes exception (it being understood that any amounts not disputed shall be final and binding). If a change proposed by Independence is disputed by EEH, then EEH and Independence shall negotiate in good faith to resolve such dispute. If, after a period of thirty (30) days following the date on which Independence gives EEH notice of any such proposed change, any such proposed change still remains disputed, then Independence and EEH shall each be entitled to adopt their own positions regarding the

allocation of the Purchase Price among the Independence Properties for federal income tax purposes. If the Purchase Price Allocation is mutually agreed (or deemed accepted), EEH, the Acquired Entities and Seller Parties (i) agree to be bound by such allocations (and agree to cause each of their applicable Representatives and Affiliates to do so); and (ii) shall file all Tax Returns (including amended returns and claims for refund) and information reports (including without limitation IRS Form 8594) in a manner consistent with the Purchase Price Allocation.; and (iii) take no position and cause their Affiliates to take no position inconsistent with such allocation for purposes of any Tax Return, unless in each case otherwise required pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

(d)Tax Treatment. Buyer Parties and Seller Parties, and their respective Affiliates and Representatives, each agree that the sale and purchase of the Independence Interests pursuant to this Agreement shall be treated for U.S. federal income Tax purposes (and for purposes of any applicable state or local Tax purposes that follows the U.S. federal income Tax treatment) in a manner consistent with the holding in Situation 2 of Revenue Ruling 99-6, 1999-1 C.B. 432 and this Section 5.10(d). Specifically, the Transaction will be treated as follows: (i) with respect to Independence Management, (A) by each of Seller Parties as if each had sold under Section 741 of the Code its respective IRM Interests to EEH in exchange for such Party’s share of the Purchase Price received pursuant to this Agreement with respect to such IRM Interests, and (B) by EEH as if it had purchased from each of Seller Parties such Party’s share of the Independence Properties in exchange for such Party’s share of the Purchase Price received pursuant to this Agreement with respect to such IRM Interests; and (ii) with respect to Independence Technology, by Independence and EEH as if EEH acquired the assets of Independence Technology from Independence. Accordingly, effective as of the Closing, (y) the Acquired Entities (and their Subsidiaries) will be disregarded entities of EEH, directly or indirectly, for U.S. federal income Tax purposes pursuant to Treasury Regulations Section 301-7701-3; and (z) Independence shall prepare and cause to be filed final year Independence Responsible Returns with respect to Independence Management in accordance with Section 5.10(a). Seller Parties further agree that, unless Independence otherwise instructs EEH in writing at least five (5) Business Days prior to the Closing pursuant to a funds flow memorandum or otherwise as to the allocation of the Purchase Price between Seller Parties, EEH shall pay or cause to be paid directly to Independence the Purchase Price on behalf of Seller Parties. No Party or any Representative or Affiliate thereof shall take a position inconsistent with the foregoing.

(e)Transfer Taxes. All Transfer Taxes incurred in connection with the transactions contemplated hereby, if any, shall be paid by Buyer Parties when due, whether levied on Buyer Parties, Independence, the Acquired Entities, or any Subsidiary thereof, and Buyer Parties shall file all necessary Tax Returns and other documentation with respect to any such Transfer Taxes. Buyer Parties shall reimburse, indemnify, defend and hold harmless Independence, the Acquired Entities and their respective Affiliates against liability for any such Transfer Taxes. The Parties will cooperate, in good faith, in the filing of any Tax Returns with respect to Transfer Taxes and the minimization, to the extent reasonably permissible under applicable Law, of the amount of any Transfer Taxes.

(f)Push-Out Election. The Parties agree that EEH and Independence Management (and any other Independence Subsidiaries, as applicable) shall make a Push-Out

Election with respect to any Pre-Closing Tax Period and any Straddle Period. Independence shall have the exclusive control, at its sole expense, of any U.S. federal income Tax Proceeding or audit relating to a Pre-Closing Tax Period (including, for the avoidance of doubt, the taxable year ending on the Closing Date) with respect to Independence Management; provided, however, Independence agrees to promptly notify EEH of the commencement of any such U.S. federal income Tax Proceeding or audit and thereafter keep EEH reasonably informed of the status and details of such Tax Proceeding or audit.

(g)Withholding. Each Party shall be entitled to deduct and withhold from any amounts otherwise payable or deliverable to any other Party or any Affiliate thereof (and such Party and its Affiliates shall indemnify, defend and hold harmless the paying party and its Affiliates against) such amounts as may be required to be deducted or withheld therefrom under applicable Law; provided that a paying Party shall use commercially reasonable efforts to provide to the other Party notice of any amounts otherwise payable that it intends to deduct and withhold at least five (5) days prior to making such withholding, and the Parties shall use commercially reasonable efforts to reduce or eliminate such withholding. To the extent such amounts are so deducted or withheld, such amounts shall be treated for all purposes as having been paid to the Person to whom such amounts would otherwise have been paid absent such deduction or withholding.

Section 5.11Voting Agreement. At the Closing, Earthstone, EnCap Investments L.P. and the Significant Holders will enter into a voting agreement pursuant to which each will agree to vote for certain directors of the Earthstone Board as provided in the voting agreement, substantially in the form attached hereto as Exhibit B (the “Voting Agreement”).

Section 5.12Indemnification and Insurance.

(a)For purposes of this Section 5.12, (i) “Indemnified Person” shall mean any person who is now, or has been or becomes at any time prior to the Closing Date, an officer, director, employee, manager or member of Independence, any Independence Company or any Independence Subsidiary and also with respect to any such Person, in his or her capacity as a director, officer, employee, manager, member, trustee or fiduciary of another corporation, foundation, partnership, joint venture, trust, pension or other employee benefit plan or enterprise (whether or not such other entity or enterprise is affiliated with Independence) serving at the request of or on behalf of Independence and together with such Person’s heirs, executors or administrators and (ii) “Proceeding” shall mean any actual or threatened claim, action, suit, proceeding or investigation, whether civil, criminal, administrative, investigative or otherwise and whether or not such claim, action, suit, proceeding or investigation results in a formal civil or criminal litigation or regulatory action.

(b)From and after the Closing Date, solely to the extent that Independence would be permitted to indemnify an Indemnified Person, Earthstone agrees to (i) indemnify and hold harmless against any cost or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages or liabilities and amounts paid in settlement in connection with any Proceeding, and provide advancement of expenses to, all Indemnified Persons to the fullest extent permitted under applicable Law and (ii) honor the provisions regarding elimination of liability of directors and managers, indemnification of officers, directors, managers and employees and advancement

of expenses contained in the Independence Charter Documents immediately prior to the Closing Date and ensure that each certificate of formation and limited liability company agreement of each Independence Company shall, for a period of six (6) years following the Closing Date, contain provisions no less favorable with respect to indemnification, advancement of expenses and exculpation of present and former directors, managers, officers, employees and agents of Independence than are presently set forth in the Independence Charter Documents. Any right of indemnification of an Indemnified Person pursuant to this Section 5.12(b) shall not be amended, repealed or otherwise modified at any time in a manner that would adversely affect the rights of such Indemnified Person as provided herein.

(c)Prior to or within ninety (90) days following the Closing Date, Earthstone shall purchase “run-off” director and officer indemnification insurance to insure the existing officers and directors of Independence, any Independence Company and any Independence Subsidiary for a period of six (6) years following the Closing Date in substantially the same amount as the director and officer indemnification insurance policy in existence for Earthstone directors and officers as of the date of this Agreement.

Section 5.13Releases.

(a)As of the Closing, each of the Seller Parties, on behalf of themselves and their Affiliates, Representatives and equity holders, hereby forever fully and irrevocably releases and discharges Buyer Parties, the Acquired Entities, and their respective predecessors, successors, direct or indirect subsidiaries, stockholders, members, partners, managers, directors, officers, employees, agents, and representatives (collectively, the “Buyer Released Parties”), from any and all Claims of any kind and nature whatsoever in law or equity, or otherwise (including claims for damages, costs, expenses, and attorneys’, brokers’ and accountants’ fees and expenses) arising out of or related to (i) Independence’s direct or indirect ownership of equity in any Acquired Entity, or (ii) Independence’s or its Affiliates or Representatives position as an employee, officer, manager, member, partner, agent or representative in any Acquired Entity, which Independence can, shall or may have against the Buyer Released Parties, whether known or unknown, suspected or unanticipated as well as anticipated and that now exist or may hereinafter accrue based on matters now known as well as unknown (collectively, the “Buyer Released Claims”), and hereby irrevocably agrees to refrain from asserting any Proceeding of any kind before any Governmental Body against any Buyer Released Party based upon any Buyer Released Claim.

representatives (collectively, the “Seller Released Parties”), from any and all Claims of any kind and nature whatsoever in law or equity, or otherwise (including claims for damages, costs, expenses, and attorneys’, brokers’ and accountants’ fees and expenses) arising out of or related to any matter occurring on or prior to the Closing Date, including any rights to indemnification or reimbursement from Independence, the Acquired Entities or any of their Affiliates, whether pursuant to contract or otherwise, and whether or not relating to Claims pending on, or asserted after, the Closing Date (collectively, the “Seller Released Claims”), and hereby irrevocably agrees to refrain from asserting any Proceeding of any kind before any Governmental Body against any Seller Released Party based upon any Seller Released Claim. From and after the Closing, the Buyer Parties, on behalf of themselves and their Affiliates and Representatives, hereby irrevocably covenant to refrain from, directly or indirectly, asserting any Claim, or commencing or causing to be commenced, any Claim of any kind against any Seller Released Party based upon any Seller Released Claim.

Section 5.14Independence Employee Matters.

(a)The Parties agree that all employees of Independence or any Independence Subsidiary (these employees, the “Independence Employees”) will remain employed by Independence Management for a transitional period of two (2) months following the Closing Date (this period, the “Transition Period”). It being understood that no Party to this Agreement can prevent any Independence Employee from resigning his or her employment with Independence Management. Within thirty (30) days after the Closing Date, with respect to each Independence Employee, Earthstone shall either (i) extend a written offer to continue the employment of such Independence Employee following the end of the Transition Period (such offer, an “Offer” and these employees, the “Offered Employees”) or (ii) provide written notice to such Independence Employee that Earthstone will not continue their employment and that their employment will be terminated at the end of the Transition Period (these employees, the “Transitional Employees”). Each Offer must provide the Independence Employee with a period of fifteen (15) days after the date of the Offer in which to elect, in writing, whether to accept or reject the Offer. The Offered Employees who accept the Offer and continue employment with Earthstone or its Subsidiaries (including Independence Management) following the Transition Period are referred to herein as the “Hired Employees.” The Offered Employees who reject a Qualifying Offer are referred to herein as “Rejecting Employees” and the Offered Employees who reject an Offer that is not a Qualifying Offer and resign their employment will be treated as Transitional Employees for all purposes under this Agreement, including for purposes of the right to receive severance payments under Section 5.14(c) below. A “Qualifying Offer” is an offer of continued employment in a comparable position with similar roles and responsibilities as applied to such Independence Employee immediately prior to Closing and at the same location as such Independence Employee’s current employment or a comparable location (i.e., within twenty-five (25) miles of such Independence Employee’s current employment), and that provides (I) a base salary or wage rate that is substantially comparable to other similarly situated

employees of Earthstone and its Subsidiaries and is within fifteen percent (15%) of such Independence Employee’s base salary or wage rate immediately prior to the Execution Date, (II) incentive compensation opportunities (including equity compensation) that are substantially comparable to those provided to other similarly situated employees of Earthstone and its Subsidiaries and (III) retirement and group health and welfare benefits that are substantially comparable to those provided to other similarly situated employees of Earthstone and its Subsidiaries.

(b)During the Transition Period, each Independence Employee shall be provided with (i) employment by Independence Management (A) on the same terms and conditions and in a comparable position as applied to such Independence Employee immediately prior to Closing and (B) at the same location as such Independence Employee’s current employment or a comparable location (i.e., within twenty-five (25) miles of such Independence Employee’s current employment), (ii) a base salary or wage rate that is no less favorable than the base salary or wage rate provided to such Independence Employees immediately prior to the Execution Date and (iii) continuation of the Independence compensation or other benefit plans and arrangements or, at Earthstone’s election, other compensation or benefit plans and arrangements provided by Earthstone that are substantially comparable individually or in the aggregate to those provided to such Independence Employees immediately prior to Closing.

(c)With respect to (i) each Transitional Employee (including an Offered Employee who becomes a Transitional Employee) who remains employed with Earthstone or its Subsidiaries (including Independence Management) through the end of the Transition Period or (ii) each Independence Employee (including any Transitional Employee) who is terminated without Cause prior to the end of the Transition Period, Earthstone shall provide (in the case of a Independence Employee terminated pursuant to Section 5.14(a)(ii)) those severance benefits set forth in Section 5.14 of the Independence Disclosure Schedule. For purposes of this Agreement, “Cause” shall mean the Independence Employee’s (1) failure to perform the duties of the employee’s position (as they may exist from time to time) to the reasonable satisfaction of Earthstone and its Subsidiaries that continues for thirty (30) days following receipt of written notice describing such failure, (2) act of fraud or dishonesty against or with respect to Earthstone or any of its Subsidiaries or customers as shall have been reasonably determined to have occurred by the Earthstone Board, (3) conviction or plea of no contest to a crime that negatively reflects on the Independence Employee’s fitness to perform the Independence Employee’s duties or harms Earthstone’s or its Subsidiaries’ reputation or business, (4) willful or gross misconduct, moral turpitude, breach of fiduciary duty that may be or is injurious to Earthstone or any of its Subsidiaries, or (5) violation of a material policy of Earthstone or any of its Subsidiaries. As a condition to receiving the severance benefits provided herein, each Transitional Employee must sign and not revoke a release of claims against Earthstone and Independence and their Affiliates in a form reasonably acceptable to Earthstone.

(d)With respect to a Hired Employee who is terminated by Earthstone or its Subsidiaries (including Independence Management) within six (6) months of the end of the Transition Period (“Terminated Employee”), Earthstone shall provide the severance benefits set forth in Section 5.14 of the Independence Disclosure Schedule. As a condition to receiving the severance benefits provided herein, each Terminated Employee must sign and not revoke a

release of claims against Earthstone and Independence and their Affiliates in a form reasonably acceptable to Earthstone.

(e)With respect to each Rejecting Employee who remains an employee of Earthstone or its Subsidiaries (including Independence Management) through the end of the Transition Period, on or as soon as practicable following such date, Earthstone shall provide severance benefits set forth in Section 5.14 of the Independence Disclosure Schedule. As a condition to receiving the severance benefits provided herein, each Rejecting Employee must sign and not revoke a release of claims against Earthstone and Independence and their Affiliates in a form reasonably acceptable to Earthstone.

(f)From and after the Closing, if Earthstone elects to provide compensation or benefit plans or arrangements to an Independence Employee as provided in Section 5.14(b), Earthstone shall give the Independence Employee receiving such benefits, as well as each Hired Employee that no longer receives benefits under Section 5.14(b), full credit for all purposes under any employee benefit plans, arrangements, collective agreements and employment-related entitlements (including under any applicable pension, 401(k), savings, medical, dental, life insurance, vacation, long-service leave or other leave entitlements, and severance or separation pay plans) that are or in the future may be provided, sponsored, maintained or contributed to by Earthstone or any of its Affiliates in which such employees are eligible to participate for such employee’s service with Independence or its Affiliates, and with any predecessor employer, to the same extent recognized by Independence and its Affiliates, except to the extent such credit would result in the duplication of benefits for the same period of service. For the avoidance of doubt no Independence Employee will be eligible to participate in an Earthstone 401(k) Plan until he or she becomes a Hired Employee. Notwithstanding the foregoing, in no event shall Earthstone be required to provide credit for such service for benefit accrual purposes under any defined benefit pension plan. In addition, to the extent the Independence Employee commences participation in any welfare benefit plan sponsored by Earthstone or its Affiliates during the plan year in which the Closing occurs, Earthstone shall (i) waive for each Independence Employee and his or her dependents, any waiting period provision, payment requirement to avoid a waiting period, pre-existing condition limitation, actively-at-work requirement and any other restriction that would prevent immediate or full participation under such plan(s) to the extent such waiting period, pre-existing condition limitation, actively-at-work requirement or other restriction would not have been applicable to such employee under the terms of the corresponding benefit plan of Independence or its Affiliate, and (ii) give full credit to each Independence Employee and his or her dependents for all co-payments and deductibles satisfied prior to the Closing in the same plan year as the Closing, and for any lifetime maximums, as if there had been a single continuous employer.

(g)This Section 5.14 shall be binding upon and inure solely to the benefit of each of the Parties to this Agreement, and nothing in this Section 5.14, express or implied, shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 5.14. Nothing contained herein, express or implied, shall be construed to establish, amend or modify, or prevent the amendment, modification or termination of, any Benefit Plan or any other program, agreement or arrangement relating to compensation or employee benefits. The Parties acknowledge and agree that the terms set forth in this

Section 5.14 shall not create any right in any Independence Employee or any other Person to any continued employment with Earthstone, Independence Management or any of their Affiliates or any compensation or benefits of any nature or kind whatsoever.

(h)Any Transitional Employee who is hired or is terminated, if applicable, must comply with such Transitional Employee’s prior agreed-upon Restrictive Covenant Agreements with Independence, including but not limited to full compliance with Covenant Not to Compete, Covenant Not to Solicit Employees and Company clients, and the non-disclosure and non-transfer of any Company Trade Secret and Confidential Information.

(i)Prior to the Closing, Independence Management shall adopt an amendment terminating the Benefit Plan that is qualified as a 401(k) plan (the “IRM 401(k) Plan”). The effective date of the termination (the “Plan Effective Date”) shall be as of the day before the Closing Date and benefit accruals shall cease as of such date. It is intended that all assets of the IRM 401(k) Plan shall be distributed as soon as reasonably practicable following the Plan Effective Date.

Section 5.15Hedging. Independence shall work in good faith with Earthstone to novate all Independence Hedge Contracts to Earthstone at the Closing or settle all Independence Hedge Contracts as instructed by Earthstone. Any cost or benefit attributable to such novation or settlement shall be Earthstone’s cost or benefit.

Section 5.16R&W Insurance. The Parties acknowledge that obtaining the R&W Insurance Policy is a material inducement to each of the Parties entering into the Transaction and is a condition to the Closing. Promptly following the execution of this Agreement, EEH shall fully comply with the R&W Conditional Binder such that the R&W Insurance Policy will become effective as of the Execution Date and the Buyer Parties shall not agree or consent to any amendment, variation, or waiver of the R&W Insurance Policy or the R&W Conditional Binder (or do anything which has a similar effect) without Independence’s prior written consent (which shall not be unreasonably withheld, conditioned or delayed). All R&W Insurance Expenses shall be paid by EEH at or prior to the Closing. To the extent that EEH intends after the Closing to make or consider making a Claim under the R&W Insurance Policy and deems the assistance and cooperation of Independence reasonably necessary or helpful in connection therewith, EEH shall so notify Independence and Independence shall use all reasonable efforts to provide such assistance and cooperation.

Section 5.17Legal Representation. Earthstone (on its behalf and, from and after the Closing, on behalf of the Independence Subsidiaries) hereby waives, and agrees to cause its Affiliates to waive, any conflicts that may arise in connection with Latham & Watkins LLP (“LW”) representing Independence, its Affiliates or any of its or their respective Representatives after Closing as such representation may relate to Earthstone, the Independence Subsidiaries or the transactions contemplated by this Agreement. Earthstone (on its behalf and, from and after the Closing, on behalf of the Independence Subsidiaries) hereby agrees that, in the event that a dispute arises after the Closing between Earthstone or any Independence Subsidiary, on the one hand, and Independence, any of its Affiliates or any of its or their respective Representatives, on the other hand, LW may represent any or all of Independence, its Affiliates or any of its or their respective Representatives in such dispute even though the interests of Independence, its

Affiliates or any of its or their respective Representatives may be directly adverse to Earthstone, the Independence Subsidiaries or any of its or their respective Affiliates or Representatives, and even though LW formerly may have represented any Independence Subsidiary in a matter substantially related to such dispute. In addition, all communications involving attorney-client confidences by Independence, its Affiliates or any of its or their respective Representatives in the course of the negotiation, documentation and consummation of the transactions contemplated hereby shall be deemed to be attorney-client confidences that belong solely to Independence, its Affiliates or any of its or their respective Representatives (and not Earthstone or any Independence Subsidiary or any of their respective Representatives). Accordingly, Earthstone and the Independence Subsidiaries shall not have access to any such communications, or to the files of LW relating to the engagement described in this Section 5.17, whether or not the Closing shall have occurred. Without limiting the generality of the foregoing, from and after the Closing, (a) Independence, its Affiliates or any of its or their respective Representatives (and not Earthstone, the Independence Subsidiaries or their respective Affiliates or Representatives) shall be the sole holders of the attorney-client privilege with respect to such engagement, and none of Earthstone, its Affiliates or any of its or their respective Representatives shall be a holder thereof, (b) to the extent that the files of LW in respect of such engagement constitute property of the client, only Independence, its Affiliates or any of its or their respective Representatives (and not Earthstone, the Independence Subsidiaries or their respective Affiliates or Representatives) shall hold such property rights and (c) LW shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to Earthstone, the Independence Subsidiaries or their respective Affiliates or Representatives by reason of any attorney-client relationship between LW and any of Independence, the Independence Subsidiaries or their respective Affiliates or Representatives or otherwise.

Section 5.18Lock-Up Agreement. At the Closing, the Significant Holders will enter into a lock-up agreement, substantially in the form attached hereto as Exhibit D (the “Lock-up Agreement”), pursuant to which, subject to certain exceptions set forth therein, they will agree to not transfer or sell any of their shares of Class A Common Stock for a period of one hundred twenty (120) days after the Closing as provided in the Lock-up Agreement.

Section 5.19Debt Financing. Earthstone (a) shall use commercially reasonable efforts to cause the Debt Financing to be consummated in accordance with its respective terms immediately prior to the Closing and (b) shall not take any action that could be reasonably expected to prevent the Debt Financing from being consummated in accordance with its respective terms immediately prior to the Closing.

Section 5.20Non-Recourse. This Agreement may only be enforced against, and any claim or cause of action based upon, arising under, out of, or in connection with, or related in any manner to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly named as Parties in the preamble of this Agreement (the “Contracting Parties”). No Person that is not a Contracting Party, including any past, present or future Representative or Affiliate of any Contracting Party or any Affiliate of any of the foregoing (each, a “Nonparty Affiliate”), shall have any liability (whether in contract, tort, at law or in equity, or granted by statute or otherwise) for any claims, causes of action or other obligations or liabilities arising under, out of, or in connection with, or related in any manner to

this Agreement or the transactions contemplated hereby, or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance or breach to the maximum extent permitted by applicable Law. To the maximum extent permitted by applicable Law, (a) each Contracting Party hereby waives and releases all such liabilities, claims, causes of action or other obligations and liabilities against any such Nonparty Affiliate, (b) each Contracting Party hereby waives and releases any and all rights, claims, demands or causes of action that may otherwise be available to avoid or disregard the entity form of a Contracting Party or otherwise impose liability of a Contracting Party on any Nonparty Affiliate, whether granted by statute based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization or otherwise, and (c) each Contracting Party disclaims any reliance upon any Nonparty Affiliate with respect to the performance of this Agreement or any representation or warranty made in, in connection with or as an inducement to this Agreement.

(a)by the mutual written consent of Earthstone and Independence;

(b)by either Earthstone or Independence:

(i)if the Closing has not occurred on or before the Outside Termination Date; provided, however, that no Party shall be entitled to terminate this Agreement under this clause (b)(i) if the Closing has failed to occur because such Party negligently or willfully failed to perform or observe in any material respect its covenants or agreements hereunder; or

(c)by Earthstone, if Independence shall have breached or failed to perform any of its representations, warranties, covenants or agreements set forth in this Agreement (or if any of the representations or warranties of Independence set forth in this Agreement shall fail to be true), which breach or failure (A) would (if it occurred or was continuing as of the Closing Date) give rise to the failure of a condition set forth in Section 6.3(a) or Section 6.3(b) and (B) is incapable of being cured, or is not cured, by Independence within thirty (30) days following receipt of written notice from Earthstone of such breach or failure; provided that Earthstone shall not have the right to terminate this Agreement pursuant to this Section 8.1(c) if Earthstone is then in material breach of any of its representations, warranties, covenants or agreements contained in this Agreement.

willfully failed to perform or observe in any material respect its covenants or agreements hereunder.

Section 8.3Effect of Termination. In the event of the termination of this Agreement as provided in Section 8.1, written notice thereof shall be given to the other Party, specifying the provision of this Agreement pursuant to which such termination is made, and this Agreement shall forthwith become null and void (other than the provisions in Section 5.3, the provisions of this Article 8 and the provisions in Article 10, all of which shall survive termination of this Agreement), and there shall be no liability on the part of any Party or its respective directors, managers, officers and Affiliates; provided, that nothing in this Section 8.3 shall relieve any Party of liability for Willful Breach or Fraud, in which case the aggrieved Party shall be entitled to all rights and remedies available at law or in equity, including seeking specific performance.

SURVIVAL AND REMEDIES; INDEMNIFICATION

Section 9.1Survival. None of the representations, warranties, covenants, agreements or undertakings set forth in this Agreement or in any instrument, document or certificate delivered in accordance with this Agreement shall survive the Closing, other than each covenant and agreement set forth in this Agreement that by its terms is to be performed following the Closing, which shall survive the Closing until fully performed. Absent Fraud, no Party or any of its respective Representatives or Affiliates shall have any liability with respect to any representation, warranty, covenant, agreement or undertaking from and after the time that such representation, warranty, covenant, agreement or undertaking ceases to survive hereunder (provided, that the foregoing shall not limit any Claim or recovery that may be available to any of the Buyer Parties or Buyer Subsidiaries under the R&W Insurance Policy). For the purposes of determining whether any representation or warranties have been breached or calculating the losses hereunder resulting from any breach of any representation or warranty set forth in this Agreement, any representation or warranty which is qualified by materiality, Material Adverse Effect or similar qualifier shall be deemed not to be so qualified. The Parties agree that, absent Fraud, (a) neither Independence nor its Representatives or Affiliates shall be liable to the R&W Insurer under the R&W Insurance Policy for subrogation claims pursuant to the R&W Insurance Policy, and (b) the R&W Insurance Policy will include a waiver of such subrogation claims for the benefit of Independence and its Affiliates.

Section 9.2Exclusive Remedy. From and after the Closing, except for claims of Fraud, the remedies provided or contemplated in Section 5.10 (Tax Matters), Section 9.1 (Survival), and Section 10.15 (Specific Performance) shall be the sole and exclusive remedies (whether at law, in equity, in contract, in tort or otherwise) for any and all claims against any Party to the extent arising under, out of, related to or in connection with this Agreement. Without limiting the generality of the foregoing and subject to Article 8, this Article 9, and Section 10.15 (Specific Performance), each of the Parties hereby waives, to the fullest extent permitted under applicable Law, any and all other rights, claims and causes of action (except for claims of Fraud) that it or any of its respective Representatives or Affiliates may have against each of the other Parties or any of its Affiliates or its or their respective Representatives with

respect to the subject matter of this Agreement, whether under any contract, misrepresentation, tort, or strict liability theory, or under applicable Law, and whether at law or in equity.

Subject to Section 2.01(c), Parent will cause the Shelf Registration Statement pursuant to this Section 2.01(b) to be continuously effective under the Securities Act from and after the date it is first declared or becomes effective until all Registrable Securities covered by the Shelf Registration Statement have been distributed in the manner set forth and as contemplated in the Shelf Registration Statement or there are no longer any Registrable Securities outstanding (the “Effectiveness Period”). The Shelf Registration Statement when declared effective (including the documents incorporated therein by reference) shall comply as to form with all applicable requirements of the Securities Act and the Exchange Act and shall not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. As soon as practicable following the date of effectiveness of such Shelf Registration Statement, but in any event within three Business Days of such date, Parent will notify the Selling Holders of the effectiveness of such Shelf Registration Statement.

Notwithstanding anything contained herein to the contrary, Parent hereby agrees that (i) the Shelf Registration Statement filed pursuant to this Section 2.01(b) shall contain all language (including on the prospectus cover sheet, the principal stockholders’ table and the plan of distribution) as may be reasonably requested by any Investor Holder to allow for a distribution to, and resale by, the direct and indirect members, stockholders or partners of such Investor Holder (each, a “Member Distribution”) and (ii) Parent shall, at the reasonable request of such Investor Holder if seeking to effect a Member Distribution, file any prospectus supplement or post-effective amendments and otherwise take any action reasonably necessary to include such language, if such language was not included in the initial Registration Statement, or revise such language if deemed reasonably necessary by such Investor Holder to effect any such Member Distribution.

(c)Delay Rights. Notwithstanding anything to the contrary contained herein, Parent may, upon written notice to (x) all Holders, delay the filing of the Shelf Registration Statement or (y) any Selling Holder whose Registrable Securities are included in the Shelf Registration Statement, suspend such Selling Holder’s use of any prospectus which is a part of the Shelf Registration Statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Shelf Registration Statement but such Selling Holder may settle any contracted sales of Registrable Securities) if Parent (i) is pursuing an acquisition,

merger, reorganization, disposition or other similar transaction and the Board of Directors of Parent determines in good faith that its ability to pursue or consummate such a transaction would be materially adversely affected by any required disclosure of such transaction in the Shelf Registration Statement or (ii) has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Board of Directors of Parent would materially adversely affect Parent; provided, however, in no event shall (A) such filing of the Shelf Registration Statement be delayed under clauses (i) or (ii) of this Section 2.01(c) for a period that exceeds 90 days or (B) such Selling Holders be suspended under clauses (i) or (ii) of this Section 2.01(c) from selling Registrable Securities pursuant to the Shelf Registration Statement for a period that exceeds an aggregate of 30 days in any 90-day period or 90 days in any 365-day period.

Parent will only exercise its suspension rights under this Section 2.01(c) if it exercises similar suspension rights with respect to any Parity Holders. If Parent exercises its suspension rights under this Section 2.01(c), then during such suspension period Parent shall not engage in any transaction involving the offer, issuance, sale or purchase of Equity Securities (whether for the benefit of Parent or a third Person), except transactions involving (I) the issuance or purchase of Equity Securities as contemplated by the Parent’s employee benefit plans or employee or director arrangements, (II) the issuance of unregistered Equity Securities to a seller as consideration for, or to a third party in order to finance or partially finance, the transaction specified under clause (i) of this Section 2.01(c) that was the basis for which the suspension rights under this Section 2.01(c) were exercised or (III) the issuance of Equity Securities to a member of EEH in connection with the redemption of Class B Common Stock and EEH Units pursuant to the EEH A&R LLC Agreement.

Section 2.02Piggyback Rights.

(a)Participation. Except as provided in Section 2.02(b), if at any time during the Effectiveness Period, Parent proposes to file (i) a shelf registration statement other than the Shelf Registration Statement (in which event Parent covenants and agrees to include thereon a description of the transaction under which the Holders acquired the Registrable Securities), (ii) a prospectus supplement to an effective shelf registration statement, other than the Shelf Registration Statement contemplated by Section 2.01(a) of this Agreement, and Holders could be included without the filing of a post-effective amendment thereto (other than a post-effective amendment that is immediately effective), or (iii) a registration statement, other than a shelf registration statement, in the case of each of clause (i), (ii) or (iii), for the sale of Class A Common Stock in an Underwritten Offering or Overnight Underwritten Offering for its own account and/or the account of another Person, then as soon as practicable but not less than ten Business Days (or one Business Day in the case of an Overnight Underwritten Offering) prior to the filing of (A) any preliminary prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b) under the Securities Act, (B) the prospectus supplement relating to such Underwritten Offering pursuant to Rule 424(b) under the Securities Act (if no preliminary

prospectus supplement is used) or (C) such registration statement (other than a Shelf Registration Statement), as the case may be (an “Underwritten Offering Filing”), then Parent shall give notice (including, but not limited to, notification by electronic mail) of such proposed Underwritten Offering (a “Piggyback Offering”) to the Holders and such notice shall offer the Holders the opportunity to include in such Underwritten Offering such number of shares of Class A Common Stock (the “Included Registrable Securities”) as each such Holder may request in writing; provided, however, that if Parent has been advised by the Managing Underwriter(s) that the inclusion of Registrable Securities for sale for the benefit of the Selling Holders will have a material adverse effect on the price, timing or distribution of the Class A Common Stock in the Underwritten Offering, then the amount of Registrable Securities to be offered for the accounts of Selling Holders shall be determined based on the provisions of Section 2.02(c) of this Agreement. The notice required to be provided in this Section 2.02(a) to each Holder (the “Piggyback Notice”) shall be provided on a Business Day pursuant to Section 3.01 hereof. Each Holder shall then have five Business Days (or one Business Day in the case of an Overnight Underwritten Offering) after the date on which the Holders received the Piggyback Notice to request inclusion of Registrable Securities in the Underwritten Offering. If no request for inclusion from a Holder is received within such period, such Holder shall have no further right to participate in such Underwritten Offering. If, at any time after giving written notice of its intention to undertake an Underwritten Offering and prior to the closing of such Underwritten Offering, the Board of Directors of Parent shall determine for any reason not to undertake or to delay such Underwritten Offering, Parent may, at its election, give written notice of such determination to the Selling Holders and (x) in the case of a determination not to undertake such Underwritten Offering, shall be relieved of its obligation to sell any Included Registrable Securities in connection with such terminated Underwritten Offering, and (y) in the case of a determination to delay such Underwritten Offering, shall be permitted to delay offering any Included Registrable Securities for the same period as the delay in the Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such offering by giving written notice to Parent of such withdrawal up to and including the time of pricing of such offering. Notwithstanding the foregoing, any Holder may deliver written notice (an “Opt-Out Notice”) to Parent requesting that such Holder not receive notice from Parent of any proposed Underwritten Offering; provided, however, that such Holder may later revoke any such Opt-Out Notice in writing. Following receipt of an Opt-Out Notice from a Holder, Parent shall not deliver any notice to such Holder pursuant to this Section 2.02(a), unless such Opt-Out Notice is revoked by such Holder.

Notwithstanding anything contained herein to the contrary, Parent hereby agrees that (i) any shelf registration statement which includes Registrable Securities pursuant to this Section 2.02(a) shall contain all language (including on the prospectus cover sheet, the principal stockholders’ table and the plan of distribution) as may be reasonably requested by such Holder to allow for a Member Distribution and (ii) Parent shall, at the reasonable request of the Holder seeking to effect a Member Distribution, file any prospectus supplement or post-effective amendments and otherwise take any action reasonably necessary to include such language, if such language was not included in the initial registration statement, or revise such language if deemed reasonably necessary by such Holder to effect such Member Distribution.

(b)Overnight Underwritten Offering Piggyback Rights. If, at any time during any Effectiveness Period, Parent proposes to file an Underwritten Offering Filing and such Underwritten Offering is expected to be launched (the “Launch Date”) after the close of trading on one trading day and priced before the open of trading on the next succeeding trading day (such execution format, an “Overnight Underwritten Offering”), then no later than one Business Day after Parent engages one or more Managing Underwriter(s) for the proposed Overnight Underwritten Offering, Parent shall notify (including, but not limited to, notice by electronic mail) the Holders of the pendency of the Overnight Underwritten Offering and such notice shall offer the Holders the opportunity to include in such Overnight Underwritten Offering such number of Registrable Securities as each such Holder may request in writing within two Business Days after such Holder receives such notice. Notwithstanding the foregoing, if Parent has been advised by the Managing Underwriter(s) that the inclusion of Registrable Securities in the Overnight Underwritten Offering for the accounts of the Selling Holders is likely to have a material adverse effect on the price, timing or distribution of the Class A Common Stock being offered in such Overnight Underwritten Offering, then the amount of Registrable Securities to be included in the Overnight Underwritten Offering for the accounts of Selling Holders shall be determined based on the provisions of Section 2.02(c) of this Agreement. If, at any time after giving written notice of its intention to execute an Overnight Underwritten Offering and prior to the closing of such Overnight Underwritten Offering, Parent determines for any reason not to undertake or to delay such Overnight Underwritten Offering, Parent shall give written notice of such determination to the Selling Holders and, (i) in the case of a determination not to undertake such Overnight Underwritten Offering, shall be relieved of its obligation to sell any Registrable Securities held by the Selling Holders in connection with such abandoned or delayed Overnight Underwritten Offering, and (ii) in the case of a determination to delay such Overnight Underwritten Offering, shall be permitted to delay offering any Registrable Securities held by the Selling Holders for the same period as the delay of the Overnight Underwritten Offering. Any Selling Holder shall have the right to withdraw such Selling Holder’s request for inclusion of such Selling Holder’s Registrable Securities in such Overnight Underwritten Offering by giving written notice to Parent of such withdrawal at least one Business Day prior to the expected Launch Date. Notwithstanding the foregoing, any Holder may deliver an Opt-Out Notice to Parent requesting that such Holder not receive notice from Parent of any proposed Overnight Underwritten Offering and, following receipt of such an Opt-Out Notice from a Holder, Parent shall not deliver any notice to such Holder pursuant to this Section 2.02(b), unless such Opt-Out Notice is revoked by such Holder.

(c)Priority of Rights. In connection with an Underwritten Offering and Overnight Underwritten Offering contemplated by Section 2.02(a) and Section 2.02(b), respectively, if the Managing Underwriter(s) of any such Underwritten Offering or Overnight Underwritten Offering, as the case may be, advises Parent that the total amount of Class A Common Stock that the Selling Holders and any other Persons intend to include in such Underwritten Offering or Overnight Underwritten Offering exceeds the number that can be sold in such Underwritten Offering or Overnight Underwritten Offering without being likely to have a material adverse effect on the price, timing or distribution of the Class A Common Stock offered in such Underwritten Offering or Overnight Underwritten Offering, as the case may be, or the market for the Class A Common Stock, then the Class A Common Stock to be included in such

Underwritten Offering or Overnight Underwritten Offering shall include the number of shares of Class A Common Stock that such Managing Underwriter(s) advise Parent can be sold without having such adverse effect (such maximum number of shares of Class A Common Stock, the “Maximum Number of Securities”), with such number to be allocated (i) first, to Parent, (ii) second, pro rata among all Selling Holders and holders of any other securities of Parent having rights of registration on parity with the Registrable Securities (“Parity Holders”) who have requested participation in such Underwritten Offering or Overnight Underwritten Offering. The pro rata allocations for each such Selling Holder or Parity Holder shall be (A) based on the percentage derived by dividing (1) the number of shares of Class A Common Stock (or other securities) that such Selling Holder or such Parity Holder has requested be included in such Underwritten Offering or Overnight Underwritten Offering by (2) the aggregate number of shares of Class A Common Stock (or other securities) that all Selling Holders and all Parity Holders have requested be included in such Underwritten Offering or Overnight Underwritten Offering or (B) as otherwise agreed by such Selling Holder or Parity Holder, as applicable.

(d)Notwithstanding anything in this Section 2.02 to the contrary, no Holder shall have any right to include any Class A Common Stock in any offering by Parent of Class A Common Stock executed pursuant to any “at the market” program that Parent may have in effect from time to time on or after the date of this Agreement.

(e)The Parent, Independence, and the Independence Stockholders hereby agree that the rights of Bold Energy Holdings, LLC (“Bold”) and its permitted assigns to register shares of Class A Common Stock under that certain Registration Rights Agreement, dated May 9, 2017, by and among the Parent, Bold and the Persons identified on Schedule I attached thereto (the “Bold Unitholders”) shall rank pari passu with the rights of Independence and the Independence Stockholders to register shares of Class A Common Stock under this Agreement. For purposes of clarity and the avoidance of doubt, the Parent, Independence and the Independence Stockholders expressly agree that Bold and the Bold Unitholders shall be Parity Holders for purposes of this Section 2.02.

Section 2.03Underwritten Offering.

(a)In the event that one or more Selling Holders holding at least $10 million (subject to adjustment pursuant to Section 3.04) of Registrable Securities (the “Offering Holders”) notify Parent in writing of their election to dispose of Registrable Securities under the Shelf Registration Statement pursuant to an Underwritten Offering or Overnight Underwritten Offering, (i) Parent shall give notice (including, but not limited to, notification by electronic mail, with such notice given no later than one Business Day after the engagement by Parent of the Managing Underwriter(s) in the case of a proposed Overnight Underwritten Offering) of such proposed Underwritten Offering or Overnight Underwritten Offering to the other Holders on a Business Day and such notice shall offer such Holders the opportunity to include in such Underwritten Offering or Overnight Underwritten Offering such number of Registrable Securities as each such Holder may request in writing (within five Business Days in the case of an Underwritten Offering that is not an Overnight Underwritten Offering and within two Business Days after the Holder receives such notice in the case of an Overnight Underwritten

Offering) and (ii) Parent will retain Underwriters selected by the Offering Holders holding a majority of the Registrable Securities to be disposed of pursuant to such Underwritten Offering or Overnight Underwritten Offering (which Underwriters shall be reasonably acceptable to the Company) subject to such sale through an Underwritten Offering or Overnight Underwritten Offering, including entering into an underwriting agreement in customary form with the Managing Underwriter(s), which underwriting agreement shall include, among other provisions, indemnities to the effect and to the extent provided in Section 2.08, and will take all reasonable actions as are requested by the Managing Underwriter(s) in order to expedite or facilitate the registration and disposition of the Registrable Securities; provided, however, that Parent shall not be required to effect more than two Underwritten Offerings or Overnight Underwritten Offerings pursuant to this Section 2.03 in any 365-day period. Parent management shall participate in a roadshow or similar marketing effort on behalf of any such Holder or Holders if gross proceeds from such Underwritten Offering or Overnight Underwritten Offering are reasonably expected to exceed $20 million. No Selling Holder may participate in such Underwritten Offering or Overnight Underwritten Offering unless such Selling Holder agrees to sell its Registrable Securities on the basis provided in such underwriting agreement and completes and executes all questionnaires, powers of attorney, indemnities and other documents reasonably and customarily required under the terms of such underwriting agreement. No Selling Holder shall be required to make any representations or warranties to or agreements with Parent or the underwriters other than representations, warranties or agreements regarding such Selling Holder and its ownership of the securities being registered on its behalf and its intended method of distribution and any other representations required by law. If any Selling Holder disapproves of the terms of an Underwritten Offering or Overnight Underwritten Offering contemplated by this Section 2.03(a), such Selling Holder may elect to withdraw therefrom by notice to Parent and the Managing Underwriter(s); provided, however, that such notice of withdrawal must be made at a time up to and including the time of pricing of such offering in order to be effective. No such withdrawal or abandonment shall affect Parent’s obligation to pay Registration Expenses.

(b)In connection with an Underwritten Offering and Overnight Underwritten Offering contemplated by Section 2.03(a), respectively, if the Managing Underwriter(s) of any such Underwritten Offering or Overnight Underwritten Offering, as the case may be, advises the Selling Holders that the total amount of Registrable Securities that the Selling Holders intend to include in such Underwritten Offering or Overnight Underwritten Offering exceeds the Maximum Number of Securities, then the Registrable Securities to be included in such Underwritten Offering or Overnight Underwritten Offering shall include the Maximum Number of Securities, with such number to be allocated (i) first, pro rata among all Selling Holders and (ii) second, to the extent the number of securities proposed to be included in such Underwritten Offering or Overnight Underwritten Offering by the Selling Holders is less than the Maximum Number of Securities, pro rata among all Parity Holders who have requested participation in such Underwritten Offering or Overnight Underwritten Offering. The pro rata allocations for each such Selling Holder or Parity Holder, as applicable, shall be (A) (1) with respect to any Selling Holder, based on the percentage derived by dividing (aa) the number of shares of Class A Common Stock (or other securities) that such Selling Holder has requested be included in such Underwritten Offering or Overnight Underwritten Offering by (bb) the aggregate number of shares of Class A Common Stock (or other securities) that all Selling Holders have requested be

included in such Underwritten Offering or Overnight Underwritten Offering, and (2) with respect to any Parity Holder, based on the percentage derived by dividing (aa) the number of shares of Class A Common Stock (or other securities) that such Parity Holder has requested be included in such Underwritten Offering or Overnight Underwritten Offering by (bb) the aggregate number of shares of Class A Common Stock (or other securities) that all Parity Holders have requested be included in such Underwritten Offering or Overnight Underwritten Offering, or (B) as otherwise agreed by such Selling Holder(s) or Parity Holder(s), as applicable.

Section 2.04Registration Procedures. In connection with its obligations under this Article II, Parent or the applicable Selling Holder, as the case may be, will, as expeditiously as possible:

(a)prepare and file with the SEC such amendments and supplements to the Shelf Registration Statement and the prospectus used in connection therewith as may be necessary to cause the Shelf Registration Statement to be effective and to keep the Shelf Registration Statement effective for the Effectiveness Period and as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by the Shelf Registration Statement;

(b)if a prospectus supplement will be used in connection with the marketing of an Underwritten Offering under a Registration Statement and the Managing Underwriter(s) at any time shall notify Parent that, in the good faith judgment of such Managing Underwriter(s), inclusion of detailed information to be used in such prospectus supplement is of material importance to the success of such Underwritten Offering, Parent and the Selling Holder shall use their commercially reasonable efforts to include such information in such prospectus supplement;

(c)furnish to each Selling Holder (i) as far in advance as reasonably practicable before filing the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any supplement or amendment thereto, upon request, copies of reasonably complete drafts of all such documents proposed to be filed (including furnishing or making available exhibits and each document incorporated by reference therein to the extent then required by the rules and regulations of the SEC), and provide each such Selling Holder the opportunity to object to any information pertaining to such Selling Holder and its plan of distribution that is contained therein and make the corrections reasonably requested by such Selling Holder with respect to such information prior to filing the Shelf Registration Statement or such other registration statement or supplement or amendment thereto, and (ii) such number of copies of the Shelf Registration Statement or such other registration statement and the prospectus included therein and any supplements and amendments thereto as such Persons may reasonably request in order to facilitate the public sale or other disposition of the Registrable Securities covered by the Shelf Registration Statement or such other registration statement;

(d)if applicable, use its reasonable best efforts to register or qualify the Registrable Securities covered by the Shelf Registration Statement or any other registration statement contemplated by this Agreement under the securities or blue sky laws of such jurisdictions as the Selling Holders or, in the case of an Underwritten Offering or Overnight Underwritten Offering, the Managing Underwriter(s) shall reasonably request, provided that Parent will not be required

to qualify generally to transact business in any jurisdiction where it is not then required to so qualify or to take any action which would subject it to general service of process in any such jurisdiction where it is not then so subject;

(e)promptly notify each Selling Holder and each underwriter of Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the filing of the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement to be used in connection therewith, or any amendment or supplement thereto, and, with respect to such Shelf Registration Statement or any other registration statement contemplated by this Agreement, when the same has become effective; and (ii) any written comments from the SEC with respect to any filing referred to in clause (i) and any written request by the SEC for amendments or supplements to the Shelf Registration Statement or any other registration statement contemplated by this Agreement or any prospectus or prospectus supplement thereto;

(f)immediately notify each Selling Holder and each underwriter of Registrable Securities, at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of (i) the happening of any event as a result of which the prospectus or prospectus supplement contained in the Shelf Registration Statement or any other registration statement contemplated by this Agreement, as then in effect, includes an untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances then existing; (ii) the issuance or threat of issuance by the SEC of any stop order suspending the effectiveness of the Shelf Registration Statement or any other registration statement contemplated by this Agreement, or the initiation of any proceedings for that purpose; or (iii) the receipt by Parent of any notification with respect to the suspension of the qualification of any Registrable Securities for sale under the applicable securities or blue sky laws of any jurisdiction. Following the provision of such notice, Parent agrees to as promptly as practicable amend or supplement the prospectus or prospectus supplement or take other appropriate action so that the prospectus or prospectus supplement does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading, in the light of the circumstances then existing, and to take such other action as is necessary to remove a stop order, suspension, threat thereof or proceedings related thereto;

(g)furnish to each Selling Holder copies of any and all transmittal letters or other correspondence with the SEC or any other governmental agency or self-regulatory body or other body having jurisdiction (including any domestic or foreign securities exchange) relating to such offering of Registrable Securities;

(h)in the case of an Underwritten Offering or Overnight Underwritten Offering, furnish upon request and addressed to the underwriters and to the Selling Holders, (i) an opinion of counsel for Parent, dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto, and a letter of like kind dated the date of the closing under the underwriting agreement, and (ii) a “comfort letter,” dated the effective date of the applicable registration statement or the date of any amendment or supplement thereto and a letter

of like kind dated the date of the closing under the underwriting agreement, in each case, signed by the independent public accountants (and, if applicable, independent reserve engineers) who have certified Parent’s financial statements included or incorporated by reference into the applicable registration statement, and each of the opinion and the “comfort letter” shall be in customary form and cover substantially the same matters with respect to such registration statement (and the prospectus and any prospectus supplement included therein) as are customarily covered in opinions of issuer’s counsel and in accountants’ (and, if applicable, independent reserve engineers’) letters delivered to the underwriters in Underwritten Offerings or Overnight Underwritten Offerings of securities, and such other matters as such underwriters or Selling Holders may reasonably request;

(i)otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least 12 months, but not more than 18 months, beginning with the first full calendar month after the effective date of such registration statement, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and Rule 158 promulgated thereunder;

(j)make available to the appropriate representatives of the Managing Underwriter(s) and Selling Holders access to such information and Parent personnel as is reasonable and customary to enable such parties to establish a due diligence defense under the Securities Act; provided that Parent need not disclose any information to any such representative unless and until such representative has entered into a customary confidentiality agreement with Parent;

(k)cause all Registrable Securities registered pursuant to this Agreement to be listed on each securities exchange or nationally recognized quotation system on which similar securities issued by Parent are then listed or quoted;

(m)provide a transfer agent and registrar for all Registrable Securities covered by such registration statement not later than the effective date of such registration statement;

(n)enter into customary agreements and take such other actions as are reasonably requested by the Selling Holders or the underwriters, if any, in order to expedite or facilitate the disposition of such Registrable Securities;

(o)if reasonably required by Parent’s transfer agent, Parent shall promptly deliver any customary authorizations, certificates and directions required by the transfer agent (and use commercially reasonable efforts to promptly deliver any other such authorizations, certificates and directions reasonably required by the transfer agent) which authorize and direct the transfer agent to transfer such Registrable Securities without legend, in accordance with applicable law, upon sale by the Holder of such Registrable Securities under the Registration Statement;

(p)if any Selling Holder could reasonably be deemed to be an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the registration statement in respect of any registration of Registrable Securities of such Selling Holder pursuant to this Agreement, and any amendment or supplement thereof (any such registration statement or amendment or supplement, a “Selling Holder Underwriter Registration Statement”), then, until the Effectiveness Period ends, (i) cooperate with such Selling Holder in allowing such Selling Holder to conduct customary “underwriter’s due diligence” with respect to Parent and satisfy its obligations in respect thereof; (ii) until the Effectiveness Period ends, at any Selling Holder request, furnish to such Selling Holder, on the date of the effectiveness of any Selling Holder Underwriter Registration Statement and thereafter no more often than on a quarterly basis, (A) a letter, dated such date, from Parent’s independent certified public accountants (and, if applicable, independent reserve engineers) in form and substance as is customarily given by independent certified public accountants (and, if applicable, independent reserve engineers) to underwriters in an underwritten public offering, addressed to such Selling Holder, (B) an opinion, dated as of such date, of counsel representing Parent for purposes of such Selling Holder Underwriter Registration Statement, in form, scope and substance as is customarily given in an underwritten public offering, including a standard “10b-5” opinion for such offering, addressed to such Selling Holder and (C) a standard officer’s certificate from the Chief Executive Officer and Chief Financial Officer of Parent addressed to such Selling Holder; and (iii) permit legal counsel of such Selling Holder to review and comment upon any Selling Holder Underwriter Registration Statement at least five Business Days prior to its filing with the SEC and all amendments and supplements to any such Selling Holder Underwriter Registration Statement within a reasonable number of days prior to their filing with the SEC and not file any Selling Holder Underwriter Registration Statement or amendment or supplement thereto in a form to which such Selling Holder’s legal counsel reasonably objects;

(q)each Selling Holder, upon receipt of notice from Parent of the happening of any event of the kind described in subsection (e) of this Section 2.04, shall forthwith discontinue disposition of the Registrable Securities until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (e) of this Section 2.04 or until it is advised in writing by Parent that the use of the prospectus may be resumed, and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by Parent, such Selling Holder will, or will request the Managing Underwriter(s), if any, to deliver to Parent (at Parent’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice; and

(r)if requested by a Selling Holder, (i) as soon as practicable incorporate in a prospectus supplement or post-effective amendment such information as such Selling Holder reasonably requests to be included therein relating to the sale and distribution of Registrable Securities, including information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the Registrable Securities to be sold in such offering; (ii) as soon as practicable make all required filings of such prospectus supplement or post-effective amendment after being notified of the

matters to be incorporated in such prospectus supplement or post-effective amendment; and (iii) as soon as practicable, supplement or make amendments to any Registration Statement.

Notwithstanding anything to the contrary in this Section 2.04, Parent will not name a Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act) in any Registration Statement or Selling Holder Underwriter Registration Statement, as applicable, without such Holder’s consent. If the Parent determines, upon advice of counsel, that Parent is required to name any Holder as an underwriter (as defined in Section 2(a)(11) of the Securities Act), and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the applicable Registration Statement and Parent shall have no further obligations hereunder with respect to Registrable Securities held by such Holder with respect to such Registration Statement or Selling Holder Registration Statement unless such Holder has not had an opportunity to conduct customary underwriter’s due diligence as set forth in Section 2.04(o) with respect to Parent at the time such Holder’s consent is sought.

Section 2.05Cooperation by Holders. Parent shall have no obligation to include in the Shelf Registration Statement Class A Common Stock of a Holder who has failed to timely furnish such information which, in the opinion of counsel to Parent, is reasonably required to be furnished or confirmed in order for the registration statement or prospectus supplement thereto, as applicable, to comply with the Securities Act.

Section 2.06Restrictions on Public Sale by Holders of Registrable Securities. Each Holder of Registrable Securities who is included in the Shelf Registration Statement agrees not to effect any public sale or distribution of the Registrable Securities for a period of up to 60 days following completion of an Underwritten Offering or Overnight Underwritten Offering of Equity Securities by Parent, provided that (i) Parent gives written notice to such Holder of the date of the commencement and termination of such period with respect to any such Underwritten Offering or Overnight Underwritten Offering and (ii) the duration of the foregoing restrictions shall be no longer than the duration of the shortest restriction generally imposed by the underwriters of such public sale or distribution on Parent or on the officers or directors or any other affiliate of Parent or unitholder of EEH on whom a restriction is imposed; provided further, that this Section 2.06 shall not apply to a Holder that holds less than $10 million of Registrable Securities, which value shall be determined by multiplying the number of Registrable Securities owned by the Class A Common Stock Price.

Section 2.07Expenses.

(a)Certain Definitions. “Registration Expenses” means all expenses incident to Parent’s performance under or compliance with this Agreement to effect the registration of Registrable Securities on the Shelf Registration Statement, an Underwritten Offering or Overnight Underwritten Offering covered under this Agreement, and/or the disposition of such securities, including, without limitation, all registration, filing, securities exchange listing and NYSE fees, all registration, filing, qualification and other fees and expenses of complying with securities or blue sky laws, fees of the Financial Industry Regulatory Authority, fees of transfer agents and registrars, all word processing, duplicating and printing expenses, and the fees and disbursements of counsel and independent public accountants for Parent, including the expenses

of any special audits or “cold comfort” letters required by or incident to such performance and compliance, and fees and expenses of one counsel engaged by the Holders of a majority of the Registrable Securities, not to exceed $20,000, in connection with the registration of the Registrable Securities on the initial Shelf Registration Statement; provided, however, that “Registration Expenses” shall not include any Selling Expenses. “Selling Expenses” means all (i) transfer taxes allocable to the sale of the Registrable Securities; (ii) fees and expenses of counsel engaged by the Holders in excess of the amounts payable by Parent under the definition of “Registration Expenses”; and (iii) commissions and discounts of brokers, dealers and underwriters.

(b)Expenses. Parent will pay all Registration Expenses as determined in good faith, including, in the case of an Underwritten Offering or Overnight Underwritten Offering, whether or not any sale is made pursuant to the Shelf Registration Statement. Each Selling Holder shall pay its pro rata share of all Selling Expenses in connection with any sale of Registrable Securities hereunder.

Section 2.08Indemnification.

(a)By Parent. In the event of a registration of any Registrable Securities under the Securities Act pursuant to this Agreement, Parent will indemnify and hold harmless each Selling Holder thereunder, its affiliates that own Registrable Securities and their respective directors and officers and each underwriter pursuant to the applicable underwriting agreement with such underwriter and each Person, if any, who controls such Selling Holder or underwriter within the meaning of the Securities Act and the Exchange Act and its directors and officers (collectively, the “Selling Holder Indemnified Persons”), against any losses, claims, damages, expenses or liabilities (including reasonable attorneys’, accountants’ and experts’ fees and expenses) (collectively, “Losses”), joint or several, to which such Selling Holder or underwriter or controlling Person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such Losses (or actions or proceedings, whether commenced or threatened, in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in (which, for the avoidance of doubt, includes documents incorporated by reference in) the Shelf Registration Statement or any other registration statement contemplated by this Agreement, any preliminary prospectus, free writing prospectus or final prospectus contained therein, or any amendment or supplement thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading or arise out of or are based upon a Selling Holder being deemed to be an “underwriter,” as defined in Section 2(a)(11) of the Securities Act, in connection with the registration statement in respect of any registration of Parent’s securities, and will reimburse each such Selling Holder Indemnified Person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such Loss or actions or proceedings; provided, however, that Parent will not be liable in any such case if and to the extent that any such Loss arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission so made in strict conformity with information furnished by such Selling Holder Indemnified Person in writing specifically for use

in the Shelf Registration Statement or such other registration statement or any prospectus contained therein or any amendment or supplement thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such Selling Holder or any such director, officer or controlling Person, and shall survive the transfer of such securities by such Selling Holder.

(b)By Each Selling Holder. Each Selling Holder agrees severally and not jointly to indemnify and hold harmless Parent, its directors and officers, and each Person, if any, who controls Parent within the meaning of the Securities Act or of the Exchange Act against any Losses to the same extent as the foregoing indemnity from Parent to the Selling Holders, but only with respect to information regarding such Selling Holder furnished in writing by or on behalf of such Selling Holder expressly for inclusion in the Shelf Registration Statement or any prospectus contained therein or any amendment or supplement thereof relating to the Registrable Securities; provided, however, that the liability of each Selling Holder shall not be greater in amount than the dollar amount of the proceeds received by such Selling Holder (net of Selling Expenses) from the sale of the Registrable Securities giving rise to such indemnification.

(c)Notice. Promptly after receipt by an indemnified party hereunder of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party hereunder, notify the indemnifying party in writing thereof, but such indemnified party’s failure to so notify the indemnifying party shall not relieve the indemnifying party from any liability which it may have to any indemnified party other than under this Section 2.08. The indemnifying party shall be entitled to participate in and, to the extent it shall wish, to assume and undertake the defense thereof with counsel reasonably satisfactory to such indemnified party and, after notice from the indemnifying party to such indemnified party of its election so to assume and undertake the defense thereof, the indemnifying party shall not be liable to such indemnified party under this Section 2.08 for any legal expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation and of liaison with counsel so selected; provided, however, that, (i) if the indemnifying party has failed to assume the defense and employ counsel reasonably acceptable to the indemnified party or (ii) if the defendants in any such action include both the indemnified party and the indemnifying party and counsel to the indemnified party shall have concluded that there may be reasonable defenses available to the indemnified party that are different from or additional to those available to the indemnifying party, or if the interests of the indemnified party reasonably may be deemed to conflict with the interests of the indemnifying party, then the indemnified party shall have the right to select a separate counsel and to assume such legal defense and otherwise to participate in the defense of such action, with the reasonable expenses and fees of one such separate counsel (firm) and other reasonable expenses related to such participation to be reimbursed by the indemnifying party as incurred. Notwithstanding any other provision of this Agreement, no indemnified party shall settle any action brought against it with respect to which it is entitled to indemnification hereunder without the consent of the indemnifying party, unless the settlement thereof imposes no liability or obligation on, and includes a complete and unconditional release from all liability of, the indemnifying party.

(d)Contribution. If the indemnification provided for in this Section 2.08 is held by a court or government agency of competent jurisdiction to be unavailable to Parent or any Selling Holder or is insufficient to hold it harmless in respect of any Losses, then each such indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such Losses as between Parent, on the one hand, and such Selling Holder, on the other hand, in such proportion as is appropriate to reflect the relative fault of Parent, on the one hand, and of such Selling Holder, on the other, in connection with the statements or omissions which resulted in such Losses, as well as any other relevant equitable considerations; provided, however, that in no event shall such Selling Holder be required to contribute an aggregate amount in excess of the dollar amount of proceeds (net of Selling Expenses) received by such Selling Holder from the sale of Registrable Securities giving rise to such indemnification. The relative fault of Parent, on the one hand, and each Selling Holder, on the other hand, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact has been made by, or relates to, information supplied by such party, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The parties hereto agree that it would not be just and equitable if contributions pursuant to this paragraph were to be determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the first sentence of this paragraph. The amount paid by an indemnified party as a result of the Losses referred to in the first sentence of this paragraph shall be deemed to include any legal and other expenses reasonably incurred by such indemnified party in connection with investigating or defending any Loss which is the subject of this paragraph. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who is not guilty of such fraudulent misrepresentation.

(e)Other Indemnification. The provisions of this Section 2.08 shall be in addition to any other rights to indemnification or contribution which an indemnified party may have pursuant to law, equity, contract or otherwise.

Section 2.09Rule 144 Reporting. With a view to making available the benefits of certain rules and regulations of the SEC that may permit the sale of the Registrable Securities to the public without registration, Parent agrees to use its reasonable best efforts to:

(a)make and keep public information regarding Parent available, as those terms are understood and defined in Rule 144 (or any successor rule or regulation to Rule 144 then in force) of the Securities Act, at all times from and after the date of this Agreement;

(b)file with the SEC in a timely manner all reports and other documents required of Parent under the Securities Act and the Exchange Act at all times from and after the date of this Agreement;

(c)so long as a Holder owns any Registrable Securities, furnish to such Holder forthwith upon request a copy of the most recent annual or quarterly report of Parent, and such other reports and documents so filed as such Holder may reasonably request in availing itself of

any rule or regulation of the SEC allowing such Holder to sell any such securities without registration; and

(d)take such further action as any Holder may reasonably request, all to the extent required from time to time to enable the Holders to sell Registrable Securities without registration under the Securities Act within the limitations of the exemption provided by Rule 144 (or any successor rule or regulation to Rule 144 then in force) under the Securities Act.

Section 2.10Transfer or Assignment of Registration Rights. The rights to cause Parent to include Registrable Securities in a Shelf Registration Statement may be transferred or assigned by any Holder to one or more transferee(s) or assignee(s) of such Registrable Securities; provided that (a) Parent is given written notice prior to any said transfer or assignment, stating the name and address of each such transferee and identifying the securities with respect to which such registration rights are being transferred or assigned, (b) each such transferee or assignee assumes in writing responsibility for its portion of the obligations of such Holder under this Agreement by executing a Joinder in the form attached hereto as Exhibit A, and (c) unless any such transferee or assignee is (i) an Independence Stockholder or (ii) an affiliate of such Holder or any other Independence Stockholder and after such transfer or assignment continues to be an affiliate of such Holder or any other Independence Stockholder, the amount of Registrable Securities transferred or assigned to such transferee or assignee shall represent at least $10 million of Registrable Securities (determined by multiplying the number of Registrable Securities owned by the Class A Common Stock Price).

Section 2.11Information by Holder. Any Holder or Holders of Registrable Securities included in any registration statement shall promptly furnish to Parent such information regarding such Holder or Holders and the distribution proposed by such Holder or Holders as Parent may reasonably request and as shall be required in connection with any registration, qualification or compliance referred to herein.

Section 2.12Limitation on Subsequent Registration Rights. From and after the date of this Agreement, Parent shall not, without the prior written consent of the Holders, enter into any agreement with any current or future holder of any securities of Parent that would allow such current or future holder to require Parent to include securities in any Piggyback Offering by Parent for its own account on a basis that is superior in any material respect to the Piggyback Offering rights granted to the Holders pursuant to Section 2.02 of this Agreement.

The existence of this right will not preclude any such Person from pursuing any other rights and remedies at law or in equity which such Person may have.

Section 3.14Amendment.

Section 3.15No Presumption. In the event any claim is made by a party relating to any conflict, omission, or ambiguity in this Agreement, no presumption or burden of proof or persuasion shall be implied by virtue of the fact that this Agreement was prepared by or at the request of a particular party or its counsel.

Section 3.16Obligations Limited to Parties to Agreement. Each of the Parties hereto covenants, agrees and acknowledges that no Person other than the Holders (and their transferees or assignees) and Parent shall have any obligation hereunder and that, notwithstanding that one or more of the Holders may be a corporation, partnership or limited liability company, no recourse under this Agreement shall be had against any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or affiliate of any Holder or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or affiliate of any of the foregoing, whether by the enforcement of any assessment or by any legal or equitable proceeding, or by virtue of any applicable law, it being expressly agreed and acknowledged that no personal liability whatsoever shall attach to, be imposed on or otherwise be incurred by any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or affiliate of any Holder or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder or affiliate of any of the foregoing, as such, for any obligations of a Holder under this Agreement or for any claim based on, in respect of or by reason of such obligation or its creation.

The obligations of each Holder under this Agreement are several and not joint with the obligations of any other Holder, and no Holder shall be responsible in any way for the performance of the obligations of any other Holder under this Agreement. Nothing contained herein, and no action taken by any Holder pursuant thereto, shall be deemed to constitute the Holders as a partnership, an association, a joint venture or any other kind of group or entity, or create a presumption that the Holders are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement. Each Holder shall be entitled to independently protect and enforce its rights, including without limitation, the rights arising out of this

Agreement, and it shall not be necessary for any other Holder to be joined as an additional party in any proceeding for such purpose.

Section 3.18Further Assurances. Parent and each of the Holders shall cooperate with each other and shall take such further action and shall execute and deliver such further documents as may be reasonably requested by any other party in order to carry out the provisions and purposes of this Agreement.

(a)Such Stockholder is the beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and unless otherwise indicated, the record owner of the shares of Common Stock (as may be adjusted from time to time pursuant to Section 4 hereof, the “Shares”) set forth opposite such Stockholder’s name on Schedule A to this Agreement, and such Shares represent all of the shares of Common Stock beneficially owned by such Stockholder as of the date hereof. For purposes of this Agreement, the term “Shares” shall include any shares of Common Stock issuable to such Stockholder upon exercise or conversion of any existing right, contract, option, or warrant to purchase, or securities convertible into or exchangeable for, Common Stock, as the case may be (“Stockholder Rights”), that are currently exercisable or convertible or become exercisable or convertible and any other shares of Common Stock such Stockholder may acquire or beneficially own during the term of this Agreement.

(b)Such Stockholder has all requisite organizational power and authority to execute and deliver this Agreement and to perform its obligations contemplated hereby. This Agreement has been validly executed and delivered by such Stockholder and, assuming that this Agreement constitutes the legal, valid and binding obligation of Earthstone and the other Parties, constitutes the legal, valid and binding obligation of such Stockholder, enforceable against such Stockholder in accordance with its terms (except insofar as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by principles governing the availability of equitable remedies).

(c)The execution and delivery of this Agreement by such Stockholder does not, and the performance of this Agreement by such Stockholder will not, (i) conflict with the certificate of formation, certificate of limited partnership, limited liability company agreement, partnership agreement or similar organizational documents of such Stockholder as presently in effect, (ii) conflict with or violate any judgment, order, decree, statute, law, ordinance, rule or regulation applicable to such Stockholder or by which it is bound or affected, (iii) (A) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a

default) under, (B) give to any other person any rights of termination, amendment, acceleration or cancellation of, or (C) result in the creation of any pledge, claim, lien, charge, encumbrance or security interest of any kind or nature whatsoever upon any of the properties or assets of the Stockholder under, any agreement, contract, indenture, note or instrument to which such Stockholder is a party or by which it is bound or affected, except for such breaches, defaults or other occurrences that would not prevent or materially delay the performance by such Stockholder of any of such Stockholder’s obligations under this Agreement, or (iv) except for applicable requirements, if any, of the Exchange Act, the Securities Act of 1933, as amended (the “Securities Act”), or the New York Stock Exchange (the “NYSE”), require any filing by such Stockholder with, or any permit, authorization, consent or approval of, any governmental or regulatory authority, except where the failure to make such filing or obtain such permit, authorization, consent or approval would not prevent or materially delay the performance by such Stockholder of any of such Stockholder’s obligations under this Agreement.

(d)The Shares and any certificates representing the Shares owned by such Stockholder are held by such Stockholder, or by a nominee or custodian for the benefit of such Stockholder, free and clear of all pledges, liens, charges, claims, security interests, proxies, voting trusts or agreements, understandings or arrangements or any other encumbrances whatsoever, except for any such encumbrances or proxies arising hereunder or under applicable federal and state securities laws or under the agreements set forth on Schedule B hereto. Such Stockholder owns of record or beneficially no shares of Common Stock other than such Stockholder’s Shares as set forth on Schedule A.

(e)As of the date hereof, neither such Stockholder nor any of its respective properties or assets is subject to any order, writ, judgment, injunction, decree, determination or award that would prevent or delay the consummation of the transactions contemplated hereby.

Section 2.Representations and Warranties of Earthstone. Earthstone hereby represents and warrants to the Stockholders as follows:

(a)Earthstone is a corporation duly incorporated, validly existing and in good standing under the laws of the State of Delaware. Earthstone has all requisite corporate power and authority to execute and deliver this Agreement, to perform its respective obligations hereunder and to consummate the transactions contemplated hereby, and has taken all necessary corporate action to authorize the execution, delivery and performance of this Agreement. This Agreement has been duly executed and delivered by Earthstone and, assuming that this Agreement constitutes the legal, valid and binding obligation of the other Parties, constitutes the legal, valid and binding obligation of Earthstone, enforceable against Earthstone in accordance with the terms of this Agreement (except insofar as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ rights generally, or by principles governing the availability of equitable remedies).

(b)The execution and delivery of this Agreement by Earthstone does not, and the performance of this Agreement by Earthstone will not, (i) conflict with the certificate of incorporation or bylaws or similar organizational documents of Earthstone as presently in effect, or that certain Voting Agreement, dated as of May 9, 2017 (as amended), by and among

Earthstone and the other parties thereto, (ii) conflict with or violate any judgment, order, decree, statute, law, ordinance, rule or regulation applicable to Earthstone or by which it is bound or affected, (iii) (A) result in any breach of or constitute a default (or an event that with notice or lapse of time or both would become a default) under, (B) give to any other person any rights of termination, amendment, acceleration or cancellation of, or (C) result in the creation of any pledge, claim, lien, charge, encumbrance or security interest of any kind or nature whatsoever upon any of the properties or assets of Earthstone or any of its subsidiaries under, any agreement, contract, indenture, note or instrument to which Earthstone or any of its subsidiaries is a party or by which Earthstone or any of its subsidiaries is bound or affected, except for such breaches, defaults or other occurrences that would not prevent or materially delay the performance by Earthstone of its obligations under this Agreement, or (iv) except for applicable requirements, if any, of the Exchange Act, the Securities Act or the NYSE, require any filing by Earthstone with, or any permit, authorization, consent or approval of, any governmental or regulatory authority, except where the failure to make such filing or obtain such permit, authorization, consent or approval would not prevent or materially delay the performance by Earthstone of its obligations under this Agreement.

(c)As of the date hereof, none of Earthstone, its subsidiaries or any of their respective properties or assets are subject to any order, writ, judgment, injunction, decree, determination or award that would prevent or delay the consummation of the transactions contemplated hereby.

Section 3.Board Designation Rights. The Stockholders, severally and not jointly, agree as follows:

(a) Subject to the other provisions of this Section 3, commencing on the date hereof, the Warburg Parties shall have the option and right (but not the obligation) to designate one (1) nominee to be nominated by the Company at each applicable annual (or special) meeting of stockholders of the Company (adjusted as appropriate to take into account the classified Board structure) to serve as a director on the Board (the “Designated Director”) in accordance with this Section 3. The Designated Director shall in the reasonable determination of the Board or any nominating and governance committee of the Board established from time to time (“Nominating and Governance Committee”) (i) be suitable to serve on the Board in accordance with the customary standards of suitability for directors of NYSE-listed companies and (ii) not be prohibited from serving as a director pursuant to any rule or regulation of the U.S. Securities and Exchange Commission or any national securities exchange on which the Class A Common Stock is listed or admitted to trading.

(b)Earthstone, EnCap and the Board shall take all actions necessary or advisable to effect the provisions of Section 3(a), including, effective as of the Closing, validly appointing the director designated by the Warburg Parties in writing to the Board no later than the Closing (the “Initial Director”). The Initial Director shall serve an initial term that will expire no earlier than the annual meeting of the stockholders of the Company (the “Public Stockholders”) to be held in 2023.

(c)The Warburg Parties agree (i) upon Earthstone’s request, to, and to cause the Designated Director designated by them to, timely provide Earthstone with accurate and complete information relating to such Designated Director as may be required to be disclosed by Earthstone under the Exchange Act and (ii) to cause the Designated Director designated by them to comply with the Section 16 filing obligations under the Exchange Act. At each applicable election of Directors, the Board shall nominate the Designated Director, which designee must meet the standards set forth in Section 3(a) above, as part of the slate of directors nominated by the Board for election by the Public Stockholders and shall recommend that the Public Stockholders vote for such Designated Director. Additionally, in the event of the resignation, death, or removal (for cause or otherwise) of the Designated Director, the Warburg Parties shall have the right for the ensuing sixty (60) days, subject to the other provisions of this Section 3, to designate in writing furnished to the Board or to the Nominating and Governance Committee, if applicable, the person to be appointed by the Board as the Designated Director to fill the resulting vacancy (subject to such designee meeting the standards set forth in Section 3(a) above).

(d)At all times while a Designated Director is serving as a member of the Board, and following any such Designated Director’s death, resignation, removal or other cessation as a Director in such former Designated Director’s capacity as a former Director, such Designated Director shall be entitled to all rights to indemnification and exculpation, in each case, as are then made available to any other member of the Board or any former Director, as the case may be. While serving as a Designated Director, such Designated Director shall be entitled to reimbursement for reasonable expenses consistent with Earthstone’s policies applicable to other similarly situated Directors. Earthstone shall purchase and maintain (or reimburse the Designated Director for the cost of) insurance (“D&O Insurance”), on behalf of the Designated Director, against any liability that may be asserted against, or expense that may be incurred by, such Designated Director in connection with the activities of Earthstone and its subsidiaries or such Designated Director’s activities on behalf of Earthstone and its subsidiaries, regardless of whether Earthstone or any of its subsidiaries would have the power to indemnify such Designated Director against such liability under the provisions of the organizational documents of Earthstone (as they may be amended from time to time). Such D&O Insurance shall provide coverage commensurate with that provided to independent directors of the Board and the Designated Director shall be entitled to all rights to insurance as are then made available to any other member (or former member, as applicable) of the Board by Earthstone and its subsidiaries.

(e)The option and right of the Warburg Parties to appoint a Designated Director under this Section 3 may not be transferred or assigned, in whole or in part, by the Warburg Parties without the prior written consent of Earthstone and the execution by such transferee of a joinder agreement in the form of Annex B hereto (a “Joinder”), provided that such option and right may be transferred or assigned, without the consent of Earthstone, to an Affiliate of any of the Warburg Parties so long as such transferee executes a Joinder.

(f)The Warburg Holders shall take all necessary action to cause the Designated Director to resign promptly from the Board if such Designated Director, as determined by the Board in good faith after consultation with outside legal counsel, (i) is prohibited or disqualified

from serving as a director of the Company under any rule or regulation of the SEC, NYSE, or by applicable law, (ii) has engaged in acts or omissions constituting a breach of the Designated Director’s fiduciary duties to the Company and the Public Stockholders, (iii) has engaged in acts or omissions that involve intentional misconduct or an intentional violation of law or (iv) has engaged in any transaction involving the Company from which the Designated Director derived an improper personal benefit that was not disclosed to the Board prior to the authorization of such transaction; provided, however, that the Warburg Parties shall have the right to replace such resigning Designated Director with a new Designated Director, such newly named Designated Director to be appointed promptly to the Board in place of the resigning Designated Director in the manner set forth in the Company’s governing documents for filling vacancies on the Board. Nothing in this Section 3(f) or elsewhere in this Agreement shall confer any third-party beneficiary or other rights upon any person designated hereunder as a Designated Director, whether during or after such person’s service on the Board.

(g)The Board shall not designate an executive committee or any other committee which has been delegated authority substantially similar to the authority of the Board unless the then serving Designated Director is also appointed as a member of such committee.

Section 4.Additional Covenants of the Stockholders. The Stockholders, severally and not jointly, agree as follows:

(a)Voting Agreement: For so long as this Agreement is in effect:

(i)each of the Parties (other than Earthstone) agrees that, provided that Earthstone is not in breach of its obligations under this Agreement (including Section 3), at any meeting of the Public Stockholders, however called, or at any adjournment or postponement thereof, or in connection with any written consent of the Public Stockholders or in any other circumstances upon which a vote, consent or other approval of all or some of the Public Stockholders is sought solely with respect to the matters described in this Section 4, such Party shall vote (or cause to be voted) or execute (or cause to be executed) consents with respect to, as applicable, all of the Common Stock (or other equity securities of Earthstone) owned (beneficially or of record) by such Party (or its Affiliates) as of the applicable record date in favor of (FOR) the election of the persons named in the Company’s proxy statement as the Board’s nominees for election as Directors, and against any other nominees;

(ii)with respect to any vote of the Public Stockholders held with respect to the matters set forth in Section 4(a), each of the Parties (other than Earthstone) shall, and shall cause its Affiliates which hold shares of Common Stock or other securities of Earthstone on any applicable record date to, appear at such meeting (in person or by proxy) or otherwise cause all of the shares of Common Stock or other securities of Earthstone held by such Party (or such Affiliates) to be counted as present thereat for purposes of establishing a quorum. Any vote required to be cast or consent required to be executed pursuant to this Section 4 shall be cast or executed in accordance with the applicable procedures relating thereto so as to ensure that it is duly counted for purposes of recording the results of that vote or consent; and

(iii)for so long as this Agreement is in effect, such Stockholder shall not, except as contemplated by the terms of this Agreement, take any action that would in any way restrict, limit or interfere with the performance of his, her or its obligations hereunder or the transactions contemplated hereby.

(b)Future Sales of Common Stock. Notwithstanding anything to the contrary in that certain Registration Rights Agreement, dated as of the date hereof, by and among Earthstone, Independence and the persons identified on Schedule I thereto (the “Independence RRA”) or that certain Registration Rights Agreement, dated as of May 9, 2017, by and among Earthstone, Bold Energy Holdings, LLC, a Texas limited liability company (“Bold”), and the persons identified on Schedule I thereto (the “EnCap RRA” and, together with the Independence RRA, the “Registration Rights Agreements”):
