The Company shall use its reasonable best efforts to cause the Consultants to be named insureds under the director and officer insurance policies maintained by the Company Group as soon as practicable following the execution and delivery of this Agreement. The Company shall, to the extent permitted by Applicable Law, indemnify and hold harmless Meridian from and against any and all damages, payments, losses, costs, expenses or other liabilities (including legal fees and expenses) that arise out of or are attributable to Meridian’s provision of the Services under this Agreement to the same extent Meridian would be entitled to such indemnification if Meridian were a party to such an indemnification agreement.

7. Independent Contractor. Meridian and the Consultants are engaged in a business that is independent from the Company, and Meridian and the Consultants shall perform the Services and each of their obligations hereunder as independent contractors. In no event shall Meridian or the Consultants be deemed to be employees of the Company (or any of its Affiliates), and Meridian and the Consultants shall not at any time be entitled to any employment rights or benefits from the Company (or any of its Affiliates). If any Consultant is reclassified by a state or federal agency or court as an employee of the Company or its Affiliate, the Consultant will receive no benefits except those mandated by law even if by the terms of the Company’s or its Affiliates’ benefit plans in effect at the time of such reclassification the Consultant would otherwise be eligible for such benefits. Except as specifically provided in the Services or authorized by the Board (or a committee or designee thereof), Meridian and the Consultants shall not at any time communicate or represent to any third party that in performing the Services hereunder, Meridian or the Consultants are employees of the Company (or any of its Affiliates). Meridian and the Consultants shall be solely responsible for making all applicable tax filings and remittances with respect to amounts paid pursuant to this Agreement and shall indemnify and hold the Company, its Affiliates and its and their respective representatives harmless for all claims, damages, costs and liabilities arising from Meridian’s or any Consultant’s failure to do so. It is not the purpose or intention of this Agreement or the Parties to create, and the same shall not be construed as creating, any partnership, partnership relation, joint venture, agency, or employment relationship.

(a) During the Term of this Agreement and following the expiration or termination of this Agreement, Meridian and each Consultant shall, and Meridian shall inform and direct each of its employees, attorneys, accountants, fiduciaries, advisers, representatives and Affiliates that have access to non-public information related to this Agreement, the Company or any of its Affiliates (“Confidential Information”) to, keep confidential and not disclose any Confidential Information, and not use any Confidential Information other than in connection with providing the Services in accordance with this Agreement, without the express written consent of the Company. For the purpose of clarity, any reports developed by or on the behalf of Meridian or any of the Consultants or any of the Company Group during the Term in connection with the Services shall be deemed Confidential Information. The restrictions set forth in this Section 8(a) do not apply to any disclosure required by Applicable Law (as defined below), so long as (x) prior to such disclosure the Person subject to such disclosure obligations provides the Company with written notice and an opinion of counsel stating that such disclosure is required by Applicable Law and the basis upon which the disclosure is asserted to be required, and (y) the Person subject to such disclosure obligations uses commercially reasonable efforts to oppose or mitigate any such disclosure.

(b) All Confidential Information (together with all intellectual property or other assets developed or acquired by Meridian or any Consultant in connection with the Services (the “Developed IP”)) shall remain at all times the property of the Company, and for the avoidance of doubt, all Developed IP is hereby transferred and assigned to the Company. Meridian and each of the Consultants shall immediately return to the Company (or, at the Company’s election, destroy) all Confidential Information and/or Developed IP upon a Notice of Termination or expiration of the Term and, in any event, upon the Company’s request from time to time. Upon the request of the Company, Meridian and each Consultant shall promptly provide written confirmation of the assignment of such Developed IP and compliance with this Section 8.

(d) Meridian and each Consultant acknowledge that all of the Confidential Information is or may be material, non-public and/or price-sensitive information and that the use of such information may be regulated or prohibited by Applicable Law, including securities laws relating to insider dealing and market abuse. Meridian and the Consultants each shall not use any Confidential Information for any purpose prohibited by applicable legal or regulatory authority. Any unauthorized disclosure of Confidential Information could be injurious to the Company, its clients or others and could violate federal

(e) Notwithstanding the foregoing, nothing herein shall prevent Meridian or a Consultant from making a good faith report of possible violations of Applicable Law to any governmental agency or entity or making disclosures that are protected under the whistleblower provisions of Applicable Law, and no individual (including the Consultants) shall be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is: (i) made (x) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and (y) solely for the purpose of reporting or investigating a suspected violation of law; (ii) made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal; or (iii) protected under the whistleblower provisions of applicable law. In the event a Consultant files a lawsuit for retaliation by Meridian for such Consultant’s reporting of a suspected violation of law, such Consultant may (x) disclose a trade secret to such Consultant’s attorney and (y) use the trade secret information in the court proceeding related to such lawsuit, in each case, if such Consultant (A) files any document containing such trade secret under seal and (B) does not otherwise disclose such trade secret, except pursuant to court order.

9. Document Retention; Audit Rights. The Parties shall retain documents and other information relating to the Services for at least the time period that is required by Applicable Law. Promptly following termination of this Agreement, Meridian shall deliver to such Person as the Company may designate in writing, copies of all files and records pertaining to the Company Group and other information about the assets and operations of the Company Group reasonablyrequested by the Company (which are in the possession of Meridian or the Consultants). At any time during the Term and for a period of one year following the expiration or termination of this Agreement, the Company shall have the right, exercisable at its option and expense, to review and copy the records relating to the Company Group and/or the Services maintained by Meridian and/or the Consultants, and if necessary, to verify the performance by Meridian and the Consultants of their obligations under this Agreement, and to audit such records. This audit right may be exercised from time to time (but in no event more than once in any calendar quarter) during normal business hours upon reasonable notice to Meridian. The Company shall use its commercially reasonable efforts to conduct any such audit or examination in a manner that minimizes the inconvenience or disruption to Meridian.

(a) Meridian and each Consultant shall perform the Services in compliance at all times with (i) prevailing standards of accepted business practice and ethics, (ii) all Applicable Laws (as defined below), (iii) reasonable and prudent practices, as relevant to the Services, of the oil and gas industry, and (iv) the terms of this Agreement. Meridian will (A) maintain separate accounts, financial statements, books and records from those of the Company Group and (B) prevent any funds or accounts of the Company Group from being commingled with the funds or accounts of Meridian.

(c) Meridian and the Consultants acknowledge that the Company Group is subject to and has, and will have, various compliance policies and procedures in place. As such, the engagement hereunder to provide the Services will be subject to, among other things, adherence to such applicable policies and procedures and other applicable compliance manuals for which Meridian and the Consultants are provided copies (including such policies, procedures and/or manuals as may be approved by the Board after the date hereof). Meridian hereby agrees to require the Consultants to execute any customary forms and agreements in connection therewith.

(d) Promptly (and in any event, within three (3) business days) upon becoming aware of (i) any actual or potential Conflict of Interest or (ii) any material lawsuit, claim or arbitration threatened in writing or filed against or involving Meridian, a Consultant or any of their Affiliates or any trust or vehicle owned or controlled by a Consultant or any of its Affiliates, Meridian shall disclose such actual or potential Conflict of Interest or such lawsuit, claim or arbitration to the Company. A “Conflict of Interest” shall exist when a Consultant engages in, or plans to engage in, any activities, associations, or interests that conflict with, or create an appearance of a conflict with (A) Meridian (whether or not in connection with the provision of the Services) or (B) such Consultant’s duties, responsibilities, authorities, or obligations for and to the Company (or any of its Affiliates) in connection with the provision of the Services. Notwithstanding the foregoing, Consultants may, without violating this Section 10(d), devote a portion of Consultant’s business time and attention to the activities described on Exhibit C, so long as such commitment does not adversely affect the Consultant’s ability to satisfy the Consultant’s obligations to the Company as described in this Agreement, including providing the Services.

(a) “Affiliate” shall mean, with respect to any Person, any other Person directly or indirectly controlling, controlled by, or under common control with, such Person. For this purpose, “control” shall have the meaning given such term under Rule 405 of the Securities Act of 1933. For the avoidance of doubt, with respect to the Company, the term “Affiliate” shall not include Meridian, the Consultants or any of their Affiliates.

(b) “Applicable Laws” means all statutes, laws (including all federal and state securities laws), ordinances, codes, regulations, rules or requirements of any government, governmental authority, regulatory agency or self-regulatory body (including FINRA) or exchange wherever located with jurisdiction over (i) any of Meridian, the Consultants or any of their respective businesses, properties and assets or (ii) the Company and its Affiliates.

(c) “Person” shall mean any individual, natural person, corporation (including any non-profit corporation), unlimited liability corporation, general partnership, limited partnership, limited liability partnership, joint venture, estate, trust, company (including any company limited by shares, limited liability company or joint stock company), incorporated or unincorporated association, governmental authority, firm, society or other enterprise, organization or other entity of any nature.

The words “hereof,” “hereto,” “hereby,” “herein,” “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular section or article in which such words appear. Unless the context requires otherwise, all references to laws, regulations, contracts, agreements and instruments refer to such laws, regulations, contracts, agreements and instruments as they may be amended from time to time.

12. Non-Disparagement. During the Term of this Agreement and following the expiration or termination of this Agreement, none of Meridian or the Consultants shall (and each of Meridian and the Consultants shall cause their respective Affiliates not to) disparage the Company Group or any of its directors, officers, agents, representatives, equity holders or Affiliates, either orally or in writing, at any time. In addition, during the Term of this Agreement and following the expiration or termination of this Agreement, the Company Group shall cause the members of the Board and the Company’s officers not to disparage Meridian or any of its directors, officers, agents, representatives, equity holders or Affiliates (including the Consultants), either orally or in writing, at any time. Nothing in this Section 12 will prohibit disclosure of information that is required to be disclosed to enforce this Agreement or comply with Applicable Law or order of a court or other governmental authority.

(a) This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without reference to any choice of law principle that would result in the application of any other law. (b) Subject to Section 14, each Party hereby irrevocably (i) submits to the exclusive jurisdiction of the federal courts located in Wilmington, Delaware, in connection with any action, suit or proceeding arising in connection with any disagreement, dispute, controversy or claim arising out of or relating to this Agreement, and irrevocably and unconditionally agrees that any such action, suit or proceeding shall be heard and determined in such court; and (ii) waives the defense of an inconvenient forum to the maintenance of any such action or proceeding. Each Party further agrees to accept service of process out of any of the before mentioned courts in any such dispute by registered or certified mail addressed to the Party at the address set forth in Section 16.

force by the American Arbitration Association. The arbitration proceedings shall take place in Wilmington, Delaware, or such other location as the Parties in dispute hereafter may agree upon; and such proceedings shall be governed by the laws of the State of Delaware as such laws are applied to agreements between residents of such State entered into and to be performed entirely within that State.

(b) The Parties shall agree upon one arbitrator, who shall be an individual skilled in the legal and business aspects of the subject matter of this Agreement and of the dispute. If the Parties in dispute cannot agree upon one arbitrator, each Party in dispute shall select one arbitrator and the arbitrators so selected shall select a third arbitrator. In the event the arbitrators cannot agree upon the selection of the third arbitrator, the third arbitrator shall be appointed by the American Arbitration Association at the request of any of the Parties in dispute. The arbitrators shall, if possible, be individuals skilled in the legal and business aspects of the subject matter of this Agreement and of the dispute.

(c) The decision rendered by the arbitrator or arbitrators shall be accompanied by a written opinion in support thereof. The decision shall be final and binding upon the Parties in dispute without right of appeal. Judgment upon the decision may be entered into by any court having jurisdiction thereof, or application may be made to that court for a judicial acceptance of the decision and any other enforcement. Costs of the arbitration shall be assessed by the arbitrator or arbitrators against any or all of the Parties in dispute, and shall be paid promptly by such Party. Each Party shall use best efforts to cause any proceeding conducted pursuant to Section 14(a) to be held in confidence by the American Arbitration Association, the arbitrators and each of the parties to such proceeding and their respective Affiliates, and all information relating to or disclosed by any party thereto in connection with such proceeding shall be treated by the parties thereto, their Affiliates and the arbitrators as confidential business information and no disclosure of such information shall be made by any party thereto, its Affiliates or the arbitrators without the prior written consent of the party thereto furnishing such information in connection with the arbitration proceeding, except as required by Applicable Law or to enforce any award of the arbitrators.

(d) A violation by Meridian or any Consultant of any of the covenants contained in Section 8, Section 12, Section 20 or Section 21, would cause irreparable damage to the Company in an amount that would be material but not readily ascertainable, and any remedy at law (including the payment of damages) would be inadequate. Accordingly, the Company shall be entitled (without the necessity of showing economic loss or other actual damage) to injunctive relief in any court of competent jurisdiction for any actual or threatened breach of any of such covenants in addition to any other legal or equitable remedies it may have, and Meridian and each Consultant specifically consents to the exclusive jurisdiction of the United States District Court for the District of Delaware, or if that court is unable to exercise jurisdiction for any reason, to the exclusive jurisdiction of the courts of the State of Delaware located in Wilmington, for this purpose. Meridian and each Consultant hereby waive their respective rights to any claim of improper or inconvenient venue or forum. Nothing in this Section 14(d) shall be construed as a waiver of the rights that the Company may have for damages under this Agreement or otherwise, and all of the Company’s rights shall be unrestricted.

15. Assignment; Amendment. Neither this Agreement nor any of the rights, interests, duties or obligations hereunder shall be assigned by any of Meridian or the Consultants without the express written consent of the Company. Without the prior written consent of the Company, none of Meridian or the Consultants shall engage or hire any third party for the provision of any of the Services. This Agreement may only be modified or amended with the prior written consent of both the Company and Meridian.

All notices and other communications to be given under this Agreement shall be in writing and may be given by any of the following methods: (a) personal delivery; (b) facsimile or email during normal business hours provided that receipt of any such notice given by email is confirmed; or (c) overnight delivery service. Notices shall be sent to the appropriate Party at its address given below (or at such other address for such Party as shall be specified by notice given hereunder):

17. Severability. Should any provision of this Agreement for any reason be declared invalid or unenforceable, such invalidity or unenforceability shall not affect the validity or enforceability of any of the other provisions of this Agreement, which remaining provisions shall remain in full force and effect and the application of such invalid or unenforceable provision to Persons or circumstances other than those as to which it is held invalid or unenforceable shall be valid and enforced to the fullest extent permitted by law.

(a) During the Term and for a period of one (1) year following the expiration or termination of this Agreement, each of Meridian and each Consultant agrees that it shall not, and shall cause its Affiliates not to, directly or indirectly, without obtaining the express written consent of the Company, (i) solicit (or direct to be directly or indirectly solicited) or employ or otherwise seek to employ any employee of the Company or any of its Affiliates or individual who was an employee of the Company or any of its Affiliates during the six months preceding such solicitation (the “Restricted Employees”) or (ii) solicit or encourage any customers, suppliers, partners or distributors of, or other Persons known by Meridian or such Consultant as having a business relationship with, the Company or any of its Affiliates to cease doing business with, alter the terms of its business with or otherwise alter its relationship with, the Company or any of its Affiliates, as applicable; provided, however, that this Section 20(a) shall not prohibit any advertisement or general solicitation that is not specifically targeted at the Restricted Employees.

(c) During the Term, Meridian shall cause the Consultants to provide substantially all of their business time (other than time spent serving on boards that the Board and such Consultant have agreed the Consultant may serve on, including the boards referenced in Exhibit C hereto) to performing their responsibilities with respect to the Services and, notwithstanding anything in this Agreement to the contrary, during the Term, none of Meridian, any of its subsidiaries or any of the Consultants (with respect to Meridian or any of its subsidiaries) may, without the prior written consent of the Company, (a) operate any business that is not operated in connection with the Services (other than those businesses specifically identified in Exhibit C hereto) or (b) issue any equity or other securities (or options therefor) to any Person.

(d) Meridian and each Consultant agrees that the covenants and restrictions in this Section 20 (i) are reasonable in scope and time, (ii) are reasonable restrictions to protect the legitimate business interests and goodwill of the Company and its Affiliates, and (ii) are ancillary to or a part of an otherwise enforceable contract that is supported by adequate consideration.
