(b)    For so long as this Agreement is in effect, without the prior written approval of the Warburg Parties, Earthstone shall not, and shall cause each of its subsidiaries (including EEH) not to, amend or modify any organizational documents of Earthstone or any of its subsidiaries in a way that materially, adversely and disproportionately affects the rights or privileges of the Warburg Parties or any of their respective Affiliates that owns Common Stock or other equity interests in Earthstone in relation to any other owner of equity interests of Earthstone or any of its subsidiaries.

Section 7.    Further Assurances. Each Stockholder will, from time to time, execute and deliver, or cause to be executed and delivered, such additional or further endorsements, consents and other instruments as Earthstone may reasonably request for the purpose of effectively carrying out the transactions contemplated by this Agreement.
Section 8.    Termination. This Agreement, and all rights and obligations of the Parties, shall terminate upon the earliest to occur of (a) the first date on which the Warburg Parties and their respective Permitted Transferees collectively beneficially own less than 8% of Earthstone’s outstanding Class A Common Stock; (b) the first date on which the Warburg Parties and their respective Permitted Transferees collectively beneficially own less than 10% of Earthstone’s outstanding Class A Common Stock as a result of a sale by the Warburg Parties or their respective Permitted Transferees of shares of Class A Common Stock (other than sales or transfers to one or more Affiliates of any of the Warburg Parties or their respective Permitted Transferees); and (c) the date on which the Warburg Parties or their respective Permitted Transferees, as applicable, deliver written notice to each of the other Parties terminating this Agreement in its entirety with respect to the Warburg Parties or their respective Permitted Transferees, as applicable. Notwithstanding the foregoing, Section 4(b) and Section 10 hereof shall survive any termination of this Agreement.
Section 9.    Action in Stockholder Capacity Only. Each Stockholder signs solely in its capacity as the record holder or beneficial owner of, or as the trustee of a trust whose beneficiaries are the beneficial owners of, such Stockholder’s Shares and nothing herein shall limit or affect any actions or omissions taken by or fiduciary duties of, a Stockholder or any of its affiliates, in such Stockholder’s capacity as an officer or director of Earthstone to the extent permitted by applicable law.

Delivery of an executed counterpart signature page of this Agreement by facsimile or by e-mail of a PDF document is as effective as executing and delivering this Agreement in the presence of the other Parties.

This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware, without regard to laws that may be applicable under conflicts of laws principles.

Each of the Parties agrees that a final judgment in any such action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by law. Each Party irrevocably consents to service of process in the manner provided for notices in Section 10(d). Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by law.
EACH PARTY ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE AGREEMENTS DELIVERED IN CONNECTION HEREWITH OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY. EACH PARTY CERTIFIES AND ACKNOWLEDGES THAT (A) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE EITHER OF SUCH WAIVERS, (B) IT UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF SUCH WAIVERS, (C) IT MAKES SUCH WAIVERS VOLUNTARILY, AND (D) IT HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 10(h).

(i)    Specific Performance. The Parties agree that irreparable damage may occur in the event that any provision of this Agreement is not performed in accordance with the terms of this Agreement and that each Party shall be entitled to seek specific performance of the terms of this Agreement without the posting of any bond or security in addition to any other remedy at law or equity.
(j)    Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other authority to be invalid, void, unenforceable or against its regulatory policy, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.
(k)    Several Liability. Each Party enters into this Agreement solely on its own behalf, each such Party shall solely be severally liable for any breaches of this Agreement by such Party and in no event shall any Party be liable for breaches of this Agreement by any other Party.
(l)    Non-Recourse. No past, present or future director, officer, employee, incorporator, member, partner, stockholder, agent, attorney, representative or affiliate of any Stockholder hereto or of any of their respective affiliates shall have any liability (whether in contract or in tort) for any obligations or liabilities of such party arising under, in connection with or related to this Agreement or for any claim based on, in respect of, or by reason of, the transactions contemplated hereby; provided, however, that nothing in this Section 10(l) shall limit any liability of any Stockholder hereto for its breaches of the terms and conditions of this Agreement.
(m)    Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in Earthstone any direct or indirect ownership or incidence of ownership of or with respect to any Stockholder’s Shares. All rights, ownership and economic benefits of and relating to each Stockholder’s Shares shall remain vested in and belong to such Stockholder, and Earthstone shall have no authority to direct any Stockholder in the voting or disposition of any of such Stockholder’s Shares, except as otherwise provided in this Agreement.
(n)    Waiver. No failure or delay by any Party in exercising any right, power or privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided shall be cumulative and not exclusive of any rights or remedies provided by applicable law.
(o)    Director Resignation. Upon termination of this Agreement, the Warburg Parties shall take all necessary action to cause the Designated Director to offer to promptly tender his or her resignation.
