ARTICLE II 
 EXCHANGE OF
CLASS B UNITS 
 2.1 Exchange of Class B Units. 

(a) Subject to the provisions in this Article II and the provisions of the Vine Holdings LLC Agreement, each Investment
Entity shall be entitled to exchange Class B Units (together with the same number of shares of Class B Common Stock) held by such Investment Entity at any time and from time to time. Each Investment Entity may surrender Class B Units
(together with the same number of shares of Class B Common Stock) to Vine Holdings in exchange for either (i) the delivery by Vine Holdings of a number of shares of Class A Common Stock equal to the product of (A) such number of
Class B Units surrendered multiplied by (B) the Exchange Rate or (ii), at the Issuer’s election, the delivery by Vine Holdings of cash equal to the Cash Election Amount calculated with respect to such Exchange (each, an
“Exchange”). For the avoidance of doubt, if at any time an Investment Entity surrenders all of its Class B Units to Vine Holdings, it must concurrently surrender all shares of Class B Common Stock then held by it to Vine
Holdings. 
 (b) On the date the Class B Units are surrendered pursuant to an Exchange (the “Exchange
Date”), the Issuer shall be entitled to elect (a “Cash Election”) to settle the Exchange by the delivery to the Investment Entity participating in such Exchange (in the manner provided for in
Section 2.2(a)), in lieu of the applicable number of shares of Class A Common Stock that would be received in such Exchange, an amount of cash equal to the Cash Election Amount for such Exchange. In order to make a
Cash Election with respect to an Exchange, the Issuer must provide written notice (a “Cash Election Notice”) of such election to the Investment Entity participating in the Exchange prior to 1:00 pm, Houston time, on the Business Day
after the date on which such Class B Units (together with the same number of shares of Class B Common Stock) shall have been received by Vine Holdings. If the Issuer fails to provide such written notice prior to such time, it shall not be
entitled to make a Cash Election with respect to such Exchange. 
 (c) Following settlement of the Exchange, whether by
delivery of Class A Common Stock or exercise of a Cash Election, (i) all rights of the Investment Entity participating in such Exchange as holder of such exchanged Class B Units and shares of such exchanged Class B Common Stock
shall cease and Vine Holdings shall deliver such exchanged Class B Units and such exchanged shares of Class B Common Stock to the Issuer for no additional consideration, and (ii) in the event the Issuer does not exercise a valid Cash
Election, the Investment Entity participating in such Exchange shall be treated for all purposes as having become the record holder of such shares of Class A Common Stock received in such Exchange. 

  
 3 

 (d) In the event the Issuer elects to make a Cash Election with respect to
an Investment Entity, it must simultaneously make the same Cash Election with respect to each Investment Entity that is participating in concurrently occurring Exchanges. 

2.2 Exchange Procedures. 

(a) If the Issuer makes a valid Cash Election with respect to an Exchange, then in accordance with and subject to the terms set
forth in the Vine Holdings LLC Agreement the Issuer shall deliver to Vine Holdings, and Vine Holdings shall deliver to the Investment Entity participating in such Exchange, in each case, as directed by the recipient Party by wire transfer or
ACH, the Cash Election Amount payable upon the Exchange. 
 (b) If the Issuer does not make a valid Cash Election with
respect to an Exchange, then in accordance with and subject to the terms set forth in the Vine Holdings LLC Agreement Issuer shall issue and contribute to Vine Holdings, and Vine Holdings shall deliver to the Investment Entity participating
in such Exchange, the number of shares of Class A Common Stock issuable upon the Exchange. 
 (c) Subject to the terms
set forth in the Vine Holdings LLC Agreement, the Issuer may adopt reasonable procedures for the implementation of the exchange provisions set forth in this Article II, including, without limitation, procedures for the giving of notice
of exchange and the surrender of Class B Units and shares of Class B Common Stock in the event that the Class B Units or shares of Class B Common Stock are uncertificated. 

(d) Notwithstanding anything to the contrary herein, in accordance with Section 3.6(b) of the Vine Holdings LLC Agreement,
the Issuer may in its sole discretion elect to settle any Exchange hereunder by delivering shares of Class A Common Stock or the applicable Cash Election Amount directly to an exchanging Investment Entity in exchange for such Investment
Entity’s delivery to the Issuer of the corresponding Class B Units (together with the same number of shares of Class B Common Stock). Any such transaction shall otherwise be effected on the terms and in the manner provided herein and
shall constitute an “Exchange” for all purposes of this Agreement. In the event the Issuer makes an election pursuant to this Section 2.2(d) with respect to any specific Investment Entity, it shall make the same
election with respect to all other Investment Entities who are participating in concurrently occurring Exchanges. 
 2.3 Exchange
Restrictions. 
 (a) Notwithstanding anything to the contrary contained herein, no Investment Entity shall be
entitled to exchange Class B Units and shares of Class B Common Stock, and the Issuer and Vine Holdings shall have the right to refuse to honor any request for an Exchange, if such Exchange would be prohibited under applicable law or
regulation. 

  
 4 

 (b) To the extent the Issuer or Vine Holdings determines that the
Class B Units do not meet the requirements of Treasury Regulation Section 1.7704-1(h), the Issuer or Vine Holdings may impose such restrictions on any Exchange as the Issuer or Vine Holdings may
reasonably determine to be necessary or advisable so that Vine Holdings is not treated as a “publicly traded partnership” under Section 7704 of the Code; provided, that each Investment Entity shall be entitled at any time to
exchange Class B Units (together with the same number of shares of Class B Common Stock) for Class A Common Stock, provided that the number of Class B Units surrendered by such Investment Entity (and any related person within the
meaning of Section 267(b) or Section 707(b)(1) of the Code) in such Exchanges during any thirty (30) calendar day period represent, in the aggregate, greater than 2% of the total interests in partnership capital or profits within the
meaning of Treasury Regulations Section 1.7704-1(k) (provided that such Exchange constitutes part of a “block transfer” within the meaning of Treasury Regulation
Section 1.7704-1(e)(2)). Notwithstanding anything to the contrary herein, no Exchange shall be permitted (and, if attempted, shall be void ab initio) if, in the good faith determination of the
Issuer or Vine Holdings, such an Exchange would pose a material risk that Vine Holdings would be treated as a “publicly traded partnership” under Section 7704 of the Code. 

2.4 Splits, Distributions and Reclassifications. The Exchange Rate and Cash Election Amount shall be adjusted accordingly and
equitably if there is: (1) any subdivision (by split, distribution, reclassification, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of the Class B Units and Class B
Common Stock that is not accompanied by an identical subdivision or combination of the shares of Class A Common Stock or (2) any subdivision (by split, distribution, reclassification, recapitalization or otherwise) or combination (by
reverse split, reclassification, recapitalization or otherwise) of the shares of Class A Common Stock that is not accompanied by an identical subdivision or combination of the Class B Units and Class B Common Stock. In the event of a
reclassification or other similar transaction as a result of which the shares of Class A Common Stock are converted into another security, then each Investment Entity shall be entitled to receive upon exchange the amount of such security that
such Investment Entity would have received if such exchange had occurred immediately prior to the effective date of such reclassification or other similar transaction. Except as may be required in the immediately preceding sentence, no adjustments
in respect of distributions shall be made upon the exchange of any Class B Unit and share of Class B Common Stock. 
 2.5
Taxes. The delivery of shares of Class A Common Stock upon an Exchange shall be made without charge to the Investment Entity participating in such Exchange for any stamp or other similar tax in respect of such issuance unless
otherwise required by law. 
 2.6 Common Stock Issued. For the avoidance of doubt, the shares of Class A Common Stock
issued in exchange for Class B Units and shares of Class B Common Stock will not be registered under the Securities Act of 1933, as amended, but will be Registrable Securities and subject to the provisions of the Registration Rights
Agreement. 
 2.7 Reserves. At all times, Issuer shall maintain a minimum number of unencumbered shares of Class A Common
Stock reserved for issuance equal to the product of (A) the aggregate number of Class B Units held by the Investment Entities multiplied by (B) the Exchange Rate.

transferees of each of the parties hereto including, without limitation and without the need for an express assignment, subsequent holders of Class B Units and Class B Common Stock; provided that nothing herein shall be deemed to

 3.11

 3.12 Submission to Jurisdiction; Waiver of Jury Trial. 

(a) Any and all disputes which cannot be settled amicably, including any ancillary claims of any party, arising out of,
relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration
provision) shall be finally settled by arbitration conducted by a single arbitrator in Delaware in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the dispute fail to agree on the
selection of an arbitrator within thirty (30) days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the
English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings. 

(b) Notwithstanding the provisions of paragraph (a), in the case of matters relating to an Exchange, the Issuer may bring, on
behalf of the Issuer or Vine Holdings or on behalf of an Investment Entity, an action or special proceeding in any court of competent jurisdiction for the purpose of compelling a party to arbitrate, seeking temporary or preliminary relief in aid of
an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this paragraph (b), Vine Holdings and each Investment Entity (i) expressly consent to the application of paragraph (c) of this
Section 3.12 to any such action or proceeding, (ii) agree that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law
would be inadequate, and (iii) irrevocably appoint the Issuer, as their agent for service of process in connection with any such action or proceeding and agree that service of process upon such agent, who shall promptly advise Vine Holdings or
the Investment Entities, as applicable, of any such service of process, shall be deemed in every respect effective service of process upon Vine Holdings or the Investment Entities, as applicable, in any such action or proceeding. 

(c) THE PARTIES HEREBY IRREVOCABLY SUBMIT TO THE JURISDICTION OF COURTS LOCATED IN WILMINGTON, DELAWARE FOR THE PURPOSE OF ANY
JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF THIS SECTION 3.12, OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such
ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The Parties’ acknowledge that the fora
designated by this paragraph (c) have a reasonable relation to this Agreement, and to the Parties’ relationship with one another. The Parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or
hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in the preceding paragraph of this Section 3.12 and such parties agree
not to plead or claim the same. 
 (d) Notwithstanding any provision of this Agreement to the contrary, this
Section 3.12 shall be construed to the maximum extent possible to comply with the laws of the State of Delaware, including the Delaware Uniform Arbitration Act (10 Del. C. § 5701 et seq.) (the “Delaware
Arbitration Act”). If, nevertheless, it shall be determined by a court of competent jurisdiction that any provision or wording of this Section 3.12, 

  
 10 

 
including any rules of the International Chamber of Commerce, shall be invalid or unenforceable under the Delaware Arbitration Act, or other applicable law, such invalidity shall not invalidate
all of this Section 3.12. In that case, this Section 3.12 shall be construed so as to limit any term or provision so as to make it valid or enforceable within the requirements of the Delaware
Arbitration Act or other applicable law, and, in the event such term or provision cannot be so limited, this Section 3.12 shall be construed to omit such invalid or unenforceable provision. 

3.13 Counterparts. This Agreement may be executed and delivered (including by facsimile transmission) in one or more
counterparts, and by the different parties hereto in separate counterparts, each of which when executed and delivered shall be deemed to be an original but all of which taken together shall constitute one and the same agreement. Copies of executed
counterparts transmitted by telecopy or other electronic transmission service shall be considered original executed counterparts for purposes of this Section 3.13. 

3.14 Tax Treatment; Withholding. 

(a) To the extent this Agreement imposes obligations upon Vine Holdings, this Agreement shall be treated as part of the Vine
Holdings LLC Agreement as described in Section 761(c) of the Code and Sections 1.704-1(b)(2)(ii)(h) and 1.761-1(c) of the Treasury Regulations. 

(b) Each of the Issuer, Vine Holdings and their agents and affiliates shall have the right to deduct and withhold from any
consideration payable or otherwise deliverable upon an Exchange such amounts as may be required to be deducted or withheld therefrom under the Code or any provision of applicable law, and to the extent deduction and withholding is required, such
deduction and withholding may be taken in Class A Common Stock; provided that the Issuer may allow an exchanging Investment Entity to pay such taxes owed on an Exchange in cash in lieu of the Issuer withholding or deducting such Class A
Common Stock. Prior to making such deduction or withholding, the Issuer, Vine Holdings or the applicable agent or affiliate shall give written notice to the Investment Entity effecting such Exchange and reasonably cooperate with such Investment
Entity to reduce or avoid any such deduction or withholding. To the extent such amounts are so deducted or withheld and paid over to the relevant governmental authority, such amounts shall be treated for all purposes under this Agreement as having
been paid to the applicable Investment Entity, and, if withholding is taken in Class A Common Stock, the relevant withholding party shall be treated as having sold such Class A Common Stock on behalf of such Investment Entity for an amount
of cash equal to the fair market value thereof at the time of such deemed sale and paid such cash proceeds to the relevant governmental authority. 

3.15 Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Delaware.

 3.16 Effective Date. This Agreement shall become effective upon the closing of the IPO and shall be of no force and effect
(i) prior to the closing of the IPO and (ii) if the closing of the IPO has not been consummated within ten (10) Business Days from the date of this Agreement.

Section 2.    Acceptance and Term of Employment. 

The Company agrees to employ Executive, and Executive agrees to serve the Company, on the terms and conditions set forth herein. The Initial
Term of Employment shall commence on the Effective Date and continue until the Determination Date (as defined below), unless earlier terminated as provided in Section 8 hereof. On the Determination Date, the Term of Employment shall
automatically be extended until Executive’s employment is terminated by either party pursuant to Section 8; provided, however, that either party hereto may elect not to so extend this Agreement by giving written notice to the
other party prior to the Determination Date. Notwithstanding the foregoing, the Term of Employment shall automatically be extended indefinitely until terminated pursuant to Section 8 if the Company consummates an acquisition of a business or
operational assets (an “Acquisition”). For purposes hereof, the “Determination Date” is the second anniversary of the Effective Date; provided, however, that if the Company has not consummated an
Acquisition before the second anniversary of the Effective Date but is, as of such date, party to an agreement to consummate an Acquisition (an “Acquisition Agreement”), the Determination Date shall be extended until the Acquisition
Agreement is terminated or expires, at which point either party may elect within 30 days after such extended Determination Date not to extend this Agreement by giving written notice to the other party. For the sake of clarity, the Term of Employment
shall automatically be extended if the transactions contemplated by an Acquisition Agreement are, in fact, consummated. 

Section 3.    Position, Duties, and Responsibilities; Place of Performance. 

(a)    Position, Duties, and Responsibilities. During the Term of Employment, Executive shall be employed and serve
as the Chief Executive Officer of the Company Group (together with such other position or positions consistent with Executive’s title as the Board shall specify from time to time) and shall have such duties and responsibilities commensurate
with such title, including managing the day-to-day business activities of the Company (subject to 

 
operating guidelines and budgets established by the Board from time to time). Executive also agrees to serve as an officer and/or director of any other member of the Company Group, in each case
without additional compensation. 
 (b)    Performance. Executive shall devote Executive’s full business
time, attention, skill, and best efforts to the performance of Executive’s duties under this Agreement and shall not engage in any other business or occupation during the Term of Employment, including, without limitation, any activity that
(x) conflicts with the interests of the Company or any other member of the Company Group, (y) interferes with the proper and efficient performance of Executive’s duties for the Company, or (z) interferes with Executive’s
exercise of judgment in the Company’s best interests. Notwithstanding the foregoing, nothing herein shall preclude Executive from (i) serving, with the prior written consent of the Board, as a member of the boards of directors or advisory
boards (or their equivalents in the case of a non-corporate entity) of non-competing businesses and charitable organizations, (ii) engaging in charitable activities
and community affairs, and (iii) managing Executive’s personal investments and affairs; provided, however, that the activities set out in clauses (i), (ii), and (iii) shall be limited by Executive so as not to materially
interfere, individually or in the aggregate, with the performance of Executive’s duties and responsibilities hereunder. Further, the Company acknowledges that in connection with his employment hereunder, Blackstone Energy Partners L.P.
(“Blackstone”) will appoint Executive to serve as a Senior Advisor of Blackstone, which appointment may also include service as a board member of one or more other portfolio companies of Blackstone and its affiliates (the
“Advisor Appointment”), and agrees that Executive may provide services in connection with the Advisor Appointment during the Term of Employment, and that the provision of any such services shall not be in conflict with, or otherwise
prohibited by, the provisions of this Agreement. 
 (c)    Principal Place of Employment. Executive’s
principal place of employment shall be in Plano, Texas, although Executive understands and agrees that Executive may be required to travel from time to time for business reasons. 

Section 4.    Compensation. 

During the Term of Employment, Executive shall be entitled to the following compensation: 

(a)    Base Compensation. Executive shall be provided annualized Base Compensation, payable in accordance with the
regular payroll practices of the Company, of $350,000, with adjustments, if any, as may be approved in writing by the Board. 

(b)    Annual Bonus. Following the consummation of an Acquisition, Executive shall be eligible to earn an annual
bonus with respect to each fiscal year of the Company ending during the remaining Term of Employment (pro-rated for any fractional years) (the “Annual Bonus”), subject to Section 8. The
Annual Bonus may be an amount up to two times Base Compensation and the Board may, in its sole discretion, require Executive to reinvest (subject to Section 4.4 of the LP Agreement, excluding the first sentence thereof) a significant (e.g., 30-50%) portion of the after-tax proceeds thereof. The amount of the Annual Bonus opportunity and the related performance metrics shall be determined by the Board, after
consultation with 

  
 -2- 

 
Executive, based upon the value of the assets held by the Company and its subsidiaries, Blackstone precedent for similar partnerships (including taking into account the size of, and awards under,
the Incentive Plan) and other factors as determined by the Board. The Annual Bonus, to the extent earned, shall be paid in the calendar year following the applicable performance year promptly after delivery of the Company’s audited financial
statements for the relevant performance year. 
 (c)    Equity Grant. In connection with his employment
hereunder, on or as soon as practicable following the Effective Date, Executive will be granted, pursuant to the terms of the Incentive Plan, 40% of the number of Class A Units (as defined in the LP Agreement, and are intended to be
“profits interests” for U.S. tax purposes) that have been reserved for issuance under the Incentive Plan. Executive’s Class A Units shall be subject to the terms and conditions of the LP Agreement, the Incentive Plan and an award
agreement evidencing such grant of Class A Units. 
 Section 5.    Employee
Benefits. 
 During the Term of Employment, Executive shall be entitled to participate in health, insurance, retirement, and other
benefits provided generally to similarly situated employees of the Company. Executive shall also be entitled to the same number of holidays, vacation days, and sick days, as well as any other benefits, in each case as are generally allowed to
similarly situated employees of the Company in accordance with the Company policy as in effect from time to time. Nothing contained herein shall be construed to limit the Company’s ability to amend, suspend, or terminate any employee benefit
plan or policy at any time without providing Executive notice, and the right to do so is expressly reserved. 

Section 6.    Insurance. 

(a)    At any time during the Term of Employment, the Company shall have the right to insure the life of Executive
for the sole benefit of the Company, in such amounts, and with such terms, as it may determine. All premiums payable thereon shall be the obligation of the Company. Executive shall have no interest in any such policy, but agrees to cooperate with
the Company in procuring such insurance by submitting to physical examinations, supplying all information required by the insurance company, and executing all necessary documents, provided that no financial obligation is imposed on Executive by any
such documents. 
 (b)    During the Term of Employment and for a period of two years thereafter, Executive shall be
covered under a directors and officers insurance policy in amounts, and on terms and conditions, no less favorable than those policies made available by the Company to any member of the Board. 

Section 7.    Reimbursement of Business Expenses. 

Executive is authorized to incur reasonable business expenses in carrying out Executive’s duties and responsibilities under this
Agreement, and the Company shall promptly reimburse Executive for all such reasonable business expenses, subject to documentation in accordance with the Company’s policy, as in effect from time to time. 

  
 -3- 

 Section 8.    Termination of Employment. 

(a)    General. The Term of Employment shall terminate upon the earliest to occur of (i) Executive’s
death, (ii) a termination by reason of a Disability, (iii) a termination by the Company with or without Cause, (iv) a termination by Executive with or without Good Reason and
(v) non-renewal of the Initial Term of Employment. Upon any termination of Executive’s employment for any reason, except as may otherwise be requested by the Company in writing and agreed upon in
writing by Executive, Executive shall resign from any and all directorships, committee memberships, and any other positions Executive holds with the Company or any other member of the Company Group. Notwithstanding anything herein to the contrary,
the payment (or commencement of a series of payments) hereunder of any nonqualified deferred compensation (within the meaning of Section 409A of the Code) upon a termination of employment shall be delayed until such time as Executive has also
undergone a “separation from service” as defined in Treas. Reg. 1.409A-1(h), at which time such nonqualified deferred compensation (calculated as of the date of Executive’s termination of
employment hereunder) shall be paid (or commence to be paid) to Executive on the schedule set forth in this Section 8 as if Executive had undergone such termination of employment (under the same circumstances) on the date of Executive’s
ultimate “separation from service.” 
 (b)    Termination Due to Death or Disability. Executive’s
employment shall terminate automatically upon Executive’s death. The Company may terminate Executive’s employment immediately upon the occurrence of a Disability, such termination to be effective upon Executive’s receipt of written
notice of such termination. Upon Executive’s death or in the event that Executive’s employment is terminated due to Executive’s Disability, Executive or Executive’s estate or Executive’s beneficiaries, as the case may be,
shall be entitled to: 
 (i)    The Accrued Obligations; 

(ii)    A pro rata portion of the Annual Bonus (based on the portion of the fiscal year Executive was
employed by the Company) that would have been paid to Executive if his employment had not been terminated, which bonus shall be paid in accordance with Section 4(b); 

(iii)    The Severance, payable in ratable installments in accordance with the Company’s regular
payroll practices during the Severance Term; and 
 (iv)    To the extent permissible under the
Company’s group health plan, continuation, during the Severance Term (or if earlier, until the date that Executive becomes eligible to receive any health benefits as a result of subsequent employment or service during the Severance Term), of
health benefits provided to Executive and Executive’s dependents immediately prior to such termination, at the same cost applicable to active employees of the Company. 

Following Executive’s death or a termination of Executive’s employment by reason of a Disability, except as set forth in this Section 8(b),
Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

  
 -4- 

 (c)    Termination by the Company for Cause. 

(i)    The Company may terminate Executive’s employment at any time for Cause, effective upon
Executive’s receipt of written notice of such termination; provided, however, that with respect to any Cause termination relying on clause (ii) or (vi) of the definition of Cause, to the extent that such act or acts or
failure or failures to act are curable, Executive shall be given not less than ten (10) days’ written notice by the Board of the Company’s intention to terminate him for Cause, such notice to state in detail the particular act or acts
or failure or failures to act that constitute the grounds on which the proposed termination for Cause is based, and such termination shall be effective at the expiration of such ten (10) day notice period unless Executive has fully cured such
act or acts or failure or failures to act that give rise to Cause during such period. 
 (ii)    In the
event that the Company terminates Executive’s employment for Cause, Executive shall be entitled only to the Accrued Obligations. Following such termination of Executive’s employment for Cause, except as set forth in this Section 8(c),
Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

(d)    Termination by the Company without Cause. The Company may terminate Executive’s employment at any time
during the Term of Employment without Cause, effective upon Executive’s receipt of written notice of such termination. In the event that Executive’s employment is terminated by the Company without Cause (other than due to death or
Disability) during the Term of Employment, Executive shall be entitled to: 
 (i)    The Accrued
Obligations; 
 (ii)    A pro rata portion of the Annual Bonus (based on the portion of the fiscal year
Executive was employed by the Company) that would have been paid to Executive if his employment had not been terminated, which bonus shall be paid in accordance with Section 4(b); 

(iii)    The Severance, payable in ratable installments in accordance with the Company’s regular
payroll practices during the Severance Term; and 
 (iv)    To the extent permissible under the
Company’s group health plan, continuation, during the Severance Term (or if earlier, until the date that Executive becomes eligible to receive any health benefits as a result of subsequent employment or service during the Severance Term), of
health benefits provided to Executive and Executive’s dependents immediately prior to such termination, at the same cost applicable to active employees of the Company. 

Notwithstanding the foregoing, the payments and benefits described in clauses (ii) and (iii) above shall immediately terminate, and the Company shall
have no further obligations to Executive with respect thereto, in the event that Executive breaches any provision of the Non-Interference Agreement. Following such termination of Executive’s employment by
the Company without Cause, except as set forth in this Section 8(d), Executive shall have no further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Executive’s sole and exclusive remedy
upon a termination of employment by the Company without Cause shall be receipt of the Severance Benefits. 

  
 -5- 

 (e)    Termination by Executive with Good Reason. Executive may
terminate Executive’s employment with Good Reason during the Term of Employment by providing the Company ten (10) days’ written notice setting forth in reasonable specificity the event that constitutes Good Reason, which written
notice, to be effective, must be provided to the Company within sixty (60) days of the occurrence of such event. During such ten (10) day notice period, the Company shall have a cure right (if curable), and if not cured within such period,
Executive’s termination will be effective upon the expiration of such cure period, and Executive shall be entitled to the same payments and benefits as provided in Section 8(d) hereof for a termination by the Company without Cause, subject
to the same conditions on payment and benefits as described in Section 8(d) hereof. Following such termination of Executive’s employment by Executive with Good Reason, except as set forth in this Section 8(e), Executive shall have no
further rights to any compensation or any other benefits under this Agreement. For the avoidance of doubt, Executive’s sole and exclusive remedy upon a termination of employment with Good Reason shall be receipt of the Severance Benefits. 

(f)    Termination by Executive without Good Reason. Executive may terminate Executive’s employment without
Good Reason by providing the Company thirty (30) days’ written notice of such termination. In the event of a termination of employment by Executive under this Section 8(f), Executive shall be entitled only to the Accrued Obligations.
In the event of termination of Executive’s employment under this Section 8(f), the Company may, in its sole and absolute discretion, by written notice accelerate such date of termination without changing the characterization of such
termination as a termination by Executive without Good Reason. Following such termination of Executive’s employment by Executive without Good Reason, except as set forth in this Section 8(f), Executive shall have no further rights to any
compensation or any other benefits under this Agreement. 
 (g)    Termination due to
Non-Renewal of the Term of Employment. In the event that either party terminates this Agreement at or after the Determination Date by a notice of non-renewal as set
forth in Section 2 hereof, Executive shall be entitled only to the Accrued Obligations. Following such termination of Executive’s employment due to non-renewal of the Term of Employment, except as
set forth in this Section 8(g), Executive shall have no further rights to any compensation or any other benefits under this Agreement. 

(h)    Release. Notwithstanding any provision herein to the contrary, the payment of any amount or provision of any
benefit pursuant to subsection (d) or (e) of this Section 8 (other than the Accrued Obligations) (collectively, the “Severance Benefits”) shall be conditioned upon Executive’s execution and delivery to the Company of
an irrevocable Release of Claims within sixty (60) days following the date of the Executive’s termination of employment hereunder, and non-revocation of the Release of Claims (and the expiration of
any revocation period contained in such Release of Claims). If Executive fails to execute and deliver an irrevocable Release of Claims prior to the end of such sixty (60) day period, or timely revokes Executive’s acceptance of such release
following its execution, Executive shall not be entitled to any of the Severance Benefits. Further, to the extent that any of the Severance Benefits constitutes “nonqualified deferred compensation” for purposes of Section 409A of the
Code, any 

  
 -6- 

 
payment of any amount or provision of any benefit otherwise scheduled to occur prior to the sixtieth (60th) day following the date of
Executive’s termination of employment hereunder, but for the condition on executing the Release of Claims as set forth herein, shall not be made until the first regularly scheduled payroll date following such sixtieth (60th) day, after which any remaining Severance Benefits shall thereafter be provided to Executive according to the applicable schedule set forth herein. 

Section 9.    Non-Interference Agreement. 

As a condition of, and prior to commencement of, Executive’s employment with the Company, Executive shall have executed and delivered to
the Company the Non-Interference Agreement. 

Section 10.    Representations and Warranties of Executive. 

Executive represents and warrants to the Company that— 

(a)    Executive is entering into this Agreement voluntarily and that Executive’s employment hereunder and compliance
with the terms and conditions hereof will not conflict with or result in the breach by Executive of any agreement to which Executive is a party or by which Executive may be bound; 

(b)    Executive has not violated, and in connection with Executive’s employment with the Company will not violate,
any non-solicitation, non-competition, or other similar covenant or agreement of a prior employer by which Executive is or may be bound; and 

(c)    in connection with Executive’s employment with the Company, Executive will not use any confidential or
proprietary information Executive may have obtained in connection with employment with any prior employer. 

Section 11.    Taxes. 

The Company may withhold from any payments made under this Agreement all applicable taxes, including but not limited to income, employment, and
social insurance taxes, as shall be required by law. Executive acknowledges and represents that the Company has not provided any tax advice to Executive in connection with this Agreement and that Executive has been advised by the Company to seek tax
advice from Executive’s own tax advisors regarding this Agreement and payments that may be made to Executive pursuant to this Agreement, including specifically. Without limiting the foregoing, as a result of the grant of Class A Units to
Executive, as contemplated herein, Executive acknowledges that upon such grant, he will no longer be treated as an “employee” of the Company for U.S. tax purposes, but instead as “self-employed”. Upon such event, Executive
acknowledges and agrees that the Company shall no longer make deductions from payments to Executive for applicable tax withholdings, social security, unemployment, workers’ compensation or disability insurance and Executive shall be solely
responsible for the payment of such any amounts in respect of the amounts paid or payable by the Company in connection with this Agreement. 

  
 -7- 

 Section 12.    Set Off; Mitigation.

 The Company’s obligation to pay Executive the amounts provided and to make the arrangements provided hereunder shall be subject to set-off, counterclaim, or recoupment of amounts owed by Executive to the Company or its affiliates; provided, however, that to the extent any amount so subject to
set-off, counterclaim, or recoupment is payable in installments hereunder, such set-off, counterclaim, or recoupment shall not modify the applicable payment date of any
installment, and to the extent an obligation cannot be satisfied by reduction of a single installment payment, any portion not satisfied shall remain an outstanding obligation of Executive and shall be applied to the next installment only at such
time the installment is otherwise payable pursuant to the specified payment schedule. Executive shall not be required to mitigate the amount of any payment provided pursuant to this Agreement by seeking other employment or otherwise, and except as
provided in Section 8(d)(iv) hereof, the amount of any payment provided for pursuant to this Agreement shall not be reduced by any compensation or benefit earned as a result of Executive’s other employment or otherwise. 

Section 13.    Additional Section 409A Provisions. 

Notwithstanding any provision in this Agreement to the contrary— 

(a)    Any payment otherwise required to be made hereunder to Executive at any date as a result of the termination of
Executive’s employment shall be delayed for such period of time as may be necessary to meet the requirements of Section 409A(a)(2)(B)(i) of the Code (the “Delay Period”). On the first business day following the expiration
of the Delay Period, Executive shall be paid, in a single cash lump sum, an amount equal to the aggregate amount of all payments delayed pursuant to the preceding sentence, and any remaining payments not so delayed shall continue to be paid pursuant
to the payment schedule set forth herein. 
 (b)    Each payment in a series of payments hereunder shall be deemed to be
a separate payment for purposes of Section 409A of the Code. 
 (c)    To the extent that any right to
reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A of the Code), (i) any such expense
reimbursement shall be made by the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Executive, (ii) the right to reimbursement or
in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (iii) the amount of expenses eligible for reimbursement or in-kind
benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing
clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect. 

(d)    While the payments and benefits provided hereunder are intended to be structured in a manner to avoid the
implication of any penalty taxes under Section 409A of the Code, in no event whatsoever shall the Company or any of its affiliates be liable for any additional tax, interest, or penalties that may be imposed on Executive as a result of Section

  
 -8- 

 
409A of the Code or any damages for failing to comply with Section 409A of the Code (other than for withholding obligations or other obligations applicable to employers, if any, under
Section 409A of the Code). 
 Section 14.    Successors and Assigns; No Third-Party
Beneficiaries. 
 (a)    The Company. This Agreement shall inure to the benefit of the Company and its
respective successors and assigns. Neither this Agreement nor any of the rights, obligations, or interests arising hereunder may be assigned by the Company to a Person (other than another member of the Company Group, or its or their respective
successors) without Executive’s prior written consent (which shall not be unreasonably withheld, delayed, or conditioned); provided, however, that in the event of a sale of all or substantially all of the assets of the Company,
the Company may provide that this Agreement will be assigned to, and assumed by, the acquiror of such assets without Executive’s consent. 

(b)    Executive. Executive’s rights and obligations under this Agreement shall not be transferable by
Executive by assignment or otherwise, without the prior written consent of the Company; provided, however, that if Executive shall die, all amounts then payable to Executive hereunder shall be paid in accordance with the terms of this
Agreement to Executive’s devisee, legatee, or other designee, or if there be no such designee, to Executive’s estate. 

(c)    No Third-Party Beneficiaries. Except as otherwise set forth in Section 8(b) or Section 14(b)
hereof, nothing expressed or referred to in this Agreement will be construed to give any Person other than the Company, the other members of the Company Group, and Executive any legal or equitable right, remedy, or claim under or with respect to
this Agreement or any provision of this Agreement. 
 Section 15.    Waiver and
Amendments. 
 Any waiver, alteration, amendment, or modification of any of the terms of this Agreement shall be valid only if made in
writing and signed by each of the parties hereto. No waiver by either of the parties hereto of their rights hereunder shall be deemed to constitute a waiver with respect to any subsequent occurrences or transactions hereunder unless such waiver
specifically states that it is to be construed as a continuing waiver. 
 Section 16.    Severability. 

If any covenants or such other provisions of this Agreement are found to be invalid or unenforceable by a final determination of a court of
competent jurisdiction, (a) the remaining terms and provisions hereof shall be unimpaired, and (b) the invalid or unenforceable term or provision hereof shall be deemed replaced by a term or provision that is valid and enforceable and that
comes closest to expressing the intention of the invalid or unenforceable term or provision hereof. 

Section 17.    Governing Law; Waiver of Jury Trial. 

THIS AGREEMENT IS GOVERNED BY AND IS TO BE CONSTRUED UNDER THE LAWS OF THE STATE OF TEXAS. EACH PARTY TO THIS AGREEMENT

the employment of Executive. This Agreement supersedes all prior negotiations, discussions, correspondence, communications, understandings, and agreements between the parties relating to the subject matter of this Agreement.

 EXHIBIT A 

CONFIDENTIALITY, NON-INTERFERENCE, AND INVENTION ASSIGNMENT AGREEMENT 

This Confidentiality, Non-Interference, and Invention Assignment Agreement (the “Non-Interference Agreement”) is made and entered into as of May 28, 2014, by and among Vine Oil & Gas GP LLC (the “Company”), and me, as a condition of my Employment Agreement
(the “Employment Agreement”), dated even herewith, with the Company. In consideration of my continued employment with the Company and my receipt of the compensation now and hereafter paid to me by the Company, and the provision of
services to the Company and its direct and indirect subsidiaries and affiliates, including Vine Oil & Gas LP (collectively, the “Company Group”), I agree to the terms and conditions of this
Non-Interference Agreement: 
 Section 1.    Confidential Information.

 (a)    Company Group Information. I acknowledge that, during the course of my employment with the Company,
I will have access to information about the Company Group and that my employment with the Company shall bring me into close contact with confidential and proprietary information of the Company Group. In recognition of the foregoing, I agree, at all
times during the term of my employment with the Company and at all times thereafter, to hold in confidence, and not to use, except for the benefit of the Company and the Company Group, or to disclose to any person, firm, corporation, or other entity
without written authorization of the Company, any Confidential Information that I obtain or create. I further agree not to make copies of such Confidential Information except as authorized by the Company. I understand that “Confidential
Information” means information that the Company Group has or will develop, acquire, create, compile, discover, or own, that has value in or to the business of the Company Group that is not generally known and that the Company Group wishes
to maintain as confidential. I understand that Confidential Information includes, but is not limited to, any and all non-public information that relates to the actual or anticipated business and/or products,
research, or development of the Company Group, or to the technical data, trade secrets, or know-how of the Company Group, including, but not limited to, research, product plans, or other information regarding
the products or services and markets of the Company Group, customer lists, and customers (including, but not limited to, customers of the Company Group on whom I called or with whom I may become acquainted during the term of my employment),
software, developments, inventions, processes, formulas, technology, designs, drawings, engineering, marketing, finances, and other business information disclosed by the Company Group either directly or indirectly in writing, orally, or by drawings
or inspection of premises, parts, equipment, or other property of the Company Group. Notwithstanding the foregoing, Confidential Information shall not include (i) any of the foregoing items that have become publicly and widely known through no
unauthorized disclosure by me or others who were under confidentiality obligations as to the item or items involved or (ii) any information that I am required to disclose to, or by, any governmental or judicial authority; provided,
however, that in such event I will give the Company prompt written notice thereof so that the Company may seek an appropriate protective order and/or waive in writing compliance with the confidentiality provisions of this Non-Interference Agreement. 
 (b)    Former Employer Information. I represent
that my performance of all of any duties, responsibilities, and activities of employment, and my service as an employee of the Company has not breached and will not breach any agreement to keep in confidence proprietary information, knowledge, or
data acquired by me in confidence or trust prior or subsequent to the commencement of my employment with the Company, and I will not disclose to the Company, or induce the Company to use, any developments, or confidential or proprietary information
or material I may have obtained in connection with employment with any prior employer in violation of a confidentiality agreement, nondisclosure agreement, or similar agreement with such prior employer. 

  
 -1- 

 Section 2.    Developments. 

(a)    Developments Retained and Licensed. I have attached hereto, as Schedule A, a list
describing with particularity all developments, original works of authorship, developments, improvements, and trade secrets that were created or owned by me prior to the commencement of my employment (collectively referred to as “Prior
Developments”), that belong solely to me or belong to me jointly with another, that relate in any way to any of the proposed businesses, products, or research and development of the Company Group, and that are not assigned to the Company
hereunder, or if no such list is attached, I represent that there are no such Prior Developments. If, during any period during which I perform or performed services for the Company or the Company Group both before or after the date hereof (the
“Assignment Period”), whether as an officer, employee, director, independent contractor, consultant, or agent, or in any other capacity, I incorporate (or have incorporated) into a Company Group product or process a Prior
Development owned by me or in which I have an interest, I hereby grant the Company Group, and the Company Group shall have, a non-exclusive, royalty-free, irrevocable, perpetual, transferable worldwide license
(with the right to sublicense) to make, have made, copy, modify, make derivative works of, use, sell, and otherwise distribute such Prior Development as part of or in connection with such product or process. 

(b)    Assignment of Developments. I agree that I will, without additional compensation, promptly make full written
disclosure to the Company, and will hold in trust for the sole right and benefit of the Company Group, all developments, original works of authorship, inventions, concepts, know-how, improvements, trade
secrets, and similar proprietary rights, whether or not patentable or registrable under copyright or similar laws, which I may (or have previously) solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or
reduced to practice, during the Assignment Period, whether or not during regular working hours, provided they either (i) relate at the time of conception or reduction to practice of the invention to the business of the Company Group, or actual
or demonstrably anticipated research or development of the Company Group; (ii) result from or relate to any work performed for the Company Group; or (iii) are developed through the use of equipment, supplies, or facilities of the Company
Group, or any Confidential Information, or in consultation with personnel of the Company Group (collectively referred to as “Developments”). I further acknowledge that all Developments made by me (solely or jointly with others)
within the scope of and during the Assignment Period are “works made for hire” (to the greatest extent permitted by applicable law) for which I am, in part, compensated by my salary, unless regulated otherwise by law, but that, in the
event any such Development is deemed not to be a work made for hire, I hereby assign to the Company Group, or its designee, all my right, title, and interest throughout the world in and to any such Development. 

(c)    Maintenance of Records. I agree to keep and maintain adequate and current written records of all
Developments made by me (solely or jointly with others) during the Assignment Period. The records may be in the form of notes, sketches, drawings, flow charts, electronic data or recordings, or any other format. The records will be available to and
remain the sole property of the Company at all times. I agree not to remove such records from the Company’s place of business except as expressly permitted by Company policy, which may, from time to time, be revised at the sole election of the
Company for the purpose of furthering the business of the Company Group. 
 (d)    Intellectual Property Rights.
I agree to assist the Company, or its designee, at the Company’s expense, in every way to secure the rights of the Company Group in the Developments and any copyrights, patents, trademarks, service marks, database rights, domain names, mask
work rights, moral rights, and other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications,
specifications, oaths, assignments, recordations, and all other instruments that the Company 

  
 -2- 

 
shall deem necessary in order to apply for, obtain, maintain, and transfer such rights and in order to assign and convey to the Company Group the sole and exclusive right, title, and interest in
and to such Developments, and any intellectual property and other proprietary rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall
continue after the termination of the Assignment Period until the expiration of the last such intellectual property right to expire in any country of the world; provided, however, the Company shall reimburse me for my reasonable
expenses incurred in connection with carrying out the foregoing obligation. If the Company is unable because of my mental or physical incapacity or unavailability for any other reason to secure my signature to apply for or to pursue any application
for any United States or foreign patents or copyright registrations covering Developments or original works of authorship assigned to the Company Group as above, then I hereby irrevocably designate and appoint the Company and its duly authorized
officers and agents as my agent and attorney in fact to act for and in my behalf and stead to execute and file any such applications or records and to do all other lawfully permitted acts to further the application for, prosecution, issuance,
maintenance, and transfer of letters patent or registrations thereon with the same legal force and effect as if originally executed by me. I hereby waive and irrevocably quitclaim to the Company Group any and all claims, of any nature whatsoever,
that I now or hereafter have for past, present, or future infringement of any and all proprietary rights assigned to the Company Group. 

Section 3.    Returning Company Group Documents. 

I agree that, at the time of termination of my employment with the Company for any reason, I will deliver to the Company (and will not keep in
my possession, recreate, or deliver to anyone else) any and all Confidential Information and all other documents, materials, information, and property developed by me pursuant to my employment or otherwise belonging to the Company Group. I agree
further that any property situated on the Company’s premises and owned by the Company, including storage media, filing cabinets, and other work areas, is subject to inspection by personnel of the Company at any time with or without notice. 

Section 4.    Disclosure of Agreement. 

As long as it remains in effect, I will disclose the existence of this Non-Interference Agreement to
any prospective employer, partner, co-venturer, investor, or lender prior to entering into an employment, partnership, or other business relationship with such person or entity. 

Section 5.    Restrictions on Interfering. I acknowledge and agree that the covenants
contained in this Section 5 are in addition to, and not in lieu of, any similar restrictions that may exist in the Operating Agreement (as defined in the Employment Agreement), and to the extent I am a party to such Operating Agreement, the
Company may elect to enforce the covenants contained therein without limiting the Company’s rights to enforce the covenants contained herein. 

(a)    Non-Competition. During the period of my employment with the Company
(the “Employment Period”) and the Post-Termination Restricted Period, I shall not, directly or indirectly, individually or on behalf of any person, company, enterprise, or entity, or as a sole proprietor, partner, stockholder,
director, officer, principal, agent, or executive, or in any other capacity or relationship, engage in any Competitive Activities within any jurisdiction in which, at the time of my termination of employment, the Company Group is actively engaged in
the Partnership Business or has demonstrable plans, that are, or reasonably should be, known to me, to commence business activities, or participate in or make any investment in any investment which has been consummated or is being pursued or
contemplated by the Company Group. Notwithstanding anything to the contrary herein, this Section 22(y) Section 5(a) shall not apply following a No-Fault Termination; provided that during the six-month 

  
 -3- 

 
period following a No-Fault Termination , I shall not, directly or indirectly, individually or on behalf of any person, company, enterprise, or entity, or
as a sole proprietor, partner, stockholder, director, officer, principal, agent, or executive, or in any other capacity or relationship, engage in, participate in, or make any investment in or with respect to, or provide services with respect to,
any Qualifying Transaction. 
 (b)    Non-Interference. During the
Employment Period and the Post-Termination Restricted Period, I shall not, directly or indirectly for my own account or for the account of any other individual or entity, engage in Interfering Activities. 

(c)    Definitions. For purposes of this agreement: 

(i)    “Business Relation” shall mean any current or prospective client, customer, licensee, supplier,
or other business relation of the Company Group, or any such relation that was a client, customer, licensee or other business relation within the prior twelve (12) month period, in each case, with whom I transacted business or whose identity
became known to me in connection with my relationship with the Company Group, or employment by the Company. 

(ii)    “Competitive Activities” shall mean any business activities related to the Partnership Business,
as defined in the Limited Partnership Agreement of Vine Oil & Gas LP, dated as of May 28, 2014, as may be amended from time to time. 

(iii)    “Interfering Activities” shall mean (A) encouraging, soliciting, or inducing, or in any
manner attempting to encourage, solicit, or induce, any Person employed by, or providing consulting services to, the Company to terminate such Person’s employment or services (or in the case of a consultant, materially reducing such services)
with the Company; (B) hiring any individual who was employed by the Company within the six (6) month period prior to the date of such hiring; or (C) encouraging, soliciting, or inducing, or in any manner attempting to encourage,
solicit, or induce, any Business Relation to cease doing business with or reduce the amount of business conducted with the Company Group, or in any way interfering with the relationship between any such Business Relation and the Company Group. 

(iv)    “No-Fault Termination” shall mean a termination of
employment after a non-renewal of the Employment Agreement by the Company at or after the Determination Date in accordance with Section 2 of the Employment Agreement. 

(v)    “Person” shall mean any individual, corporation, partnership, limited liability company, joint
venture, association, joint-stock company, trust (charitable or non-charitable), unincorporated organization, or other form of business entity. 

(vi)    “Post-Termination Restricted Period” shall mean the period commencing on the date of the
termination of the Employment Period for any reason and ending on the twelve (12) month anniversary of such date of termination. 

(vii)    “Qualifying Transaction” shall mean any potential acquisition that I know, or reasonably should
have known, had been reviewed or considered by any member of the Company Group within six (6) months before the No-Fault Termination. 

(d)    Non-Disparagement. I agree that during the Employment Period, and at
all times thereafter, I will not make any disparaging or defamatory comments regarding the Company Group or their current or former directors, officers, members, partners or employees in any respect or make any

  
 -4- 

 
comments concerning any aspect of my relationship with the Company Group or any conduct or events which precipitated any termination of my employment from the Company. The Company Group agrees
that it shall make no public disparaging or defamatory comments regarding me during the Employment Period, and at all times thereafter. However, my obligations and the obligations of the Company Group, in each case, under this subparagraph
(d) shall not apply to disclosures required by applicable law, regulation, or order of a court or governmental agency. 

Section 6.    Reasonableness of Restrictions. 

I acknowledge and recognize the highly competitive nature of the Company’s business, that access to Confidential Information renders me
special and unique within the Company’s and Company’s industry, and that I will have the opportunity to develop substantial relationships with existing and prospective clients, accounts, customers, consultants, contractors, investors, and
strategic partners of the Company Group during the course of and as a result of my employment with the Company. In light of the foregoing, I recognize and acknowledge that the restrictions and limitations set forth in this Non-Interference Agreement are reasonable and valid in geographical and temporal scope and in all other respects and are essential to protect the value of the business and assets of the Company Group. I further
acknowledge that the restrictions and limitations set forth in this agreement will not materially interfere with my ability to earn a living following the termination of my employment with the Company and that my ability to earn a livelihood without
violating such restrictions is a material condition to my employment with the Company. 

Section 7.    Independence; Severability; Blue Pencil. 

Each of the rights enumerated in this Non-Interference Agreement shall be independent of the others and
shall be in addition to and not in lieu of any other rights and remedies available to the Company or other members of the Company Group at law or in equity. If any of the provisions of this agreement or any part of any of them is hereafter construed
or adjudicated to be invalid or unenforceable, the same shall not affect the remainder of this Non-Interference Agreement, which shall be given full effect without regard to the invalid portions. If any of the
covenants contained herein are held to be invalid or unenforceable because of the duration of such provisions or the area or scope covered thereby, I agree that the court making such determination shall have the power to reduce the duration, scope,
and/or area of such provision to the maximum and/or broadest duration, scope, and/or area permissible by law, and in its reduced form said provision shall then be enforceable. 

Section 8.    Injunctive Relief. 

I expressly acknowledge that any breach or threatened breach of any of the terms and/or conditions set forth in this Non-Interference Agreement may result in substantial, continuing, and irreparable injury to the members of the Company. Therefore, I hereby agree that, in addition to any other remedy that may be available to the
Company, the Company shall be entitled to seek injunctive relief, specific performance, or other equitable relief by a court of appropriate jurisdiction in the event of any breach or threatened breach of the terms of this Non-Interference Agreement without the necessity of proving irreparable harm or injury as a result of such breach or threatened breach. Notwithstanding any other provision to the contrary, I acknowledge and agree
that the Post-Termination Restricted Period shall be tolled during any period of violation of any of the covenants in paragraph 5 hereof and during any other period required for litigation during which the Company seeks to enforce such covenants
against me if it is ultimately determined that I was in breach of such covenants. 

  
 -5- 

 Section 9.    Cooperation. 

I agree that, for a period of eighteen months following any termination of my employment, I will continue to provide reasonable cooperation to
the Company and/or other member of the Company Group and its or their respective counsel in connection with any investigation, administrative proceeding, or litigation relating to any matter that occurred during my employment in which I was involved
or of which I have knowledge. As a condition of such cooperation, the Company shall reimburse me for reasonable out-of-pocket expenses incurred at the request of the
Company with respect to my compliance with this paragraph and shall pay me a daily consulting fee of $200 per hour. I also agree that, in the event I am subpoenaed by any person or entity (including, but not limited to, any government agency) to
give testimony or provide documents (in a deposition, court proceeding, or otherwise), that in any way relates to my employment by the Company, I will give prompt notice of such request to the Company and, to the extent permitted by applicable law,
will make no disclosure until the Company has had a reasonable opportunity to contest the right of the requesting person or entity to such disclosure. 

Section 10.    General Provisions. 

(a)    Governing Law; Waiver of Jury Trial. THE VALIDITY, INTERPRETATION, CONSTRUCTION, AND PERFORMANCE OF THIS NON-INTERFERENCE AGREEMENT SHALL BE GOVERNED BY THE LAWS OF THE UNITED STATES OF AMERICA AND THE STATE OF TEXAS, WITHOUT GIVING EFFECT TO THE PRINCIPLES OF CONFLICT OF LAWS. BY EXECUTION OF THIS NON-INTERFERENCE AGREEMENT, I HEREBY WAIVE ANY RIGHT TO TRIAL BY JURY IN CONNECTION WITH ANY SUIT, ACTION, OR PROCEEDING UNDER OR IN CONNECTION WITH THIS NON-INTERFERENCE
AGREEMENT. 
 (b)    Entire Agreement. Except as set forth in the Operating Agreement, this Non-Interference Agreement sets forth the entire agreement and understanding between the Company and me relating to the subject matter herein and merges all prior discussions between us. No modification or amendment
to this Non-Interference Agreement, nor any waiver of any rights under this Non-Interference Agreement, will be effective unless in writing signed by the party to be
charged. Any subsequent change or changes in my duties, obligations, rights, or compensation will not affect the validity or scope of this Non-Interference Agreement. 

(c)    No Right of Continued Employment. I acknowledge and agree that nothing contained herein shall be construed
as granting me any right to continued employment by the Company, and the right of the Company to terminate my employment at any time and for any reason, with or without Cause (as defined in the Employment Agreement), is specifically reserved. 

(d)    Successors and Assigns. This Non-Interference Agreement will be
binding upon my heirs, executors, administrators, and other legal representatives and will be for the benefit of the Company and its successors and assigns. I expressly acknowledge and agree that this
Non-Interference Agreement may be assigned without my consent to any other member of the Company Group as well as any purchaser of all or substantially all of the assets of the Company. 

(e)    Survival. The provisions of this Non-Interference Agreement shall
survive the termination of my employment with the Company and/or the assignment of this Non-Interference Agreement by the Company to any successor in interest or other assignee.

GENERAL RELEASE 

I, Eric Marsh, in consideration of and subject to the performance by Vine Oil & Gas GP LLC (together with its subsidiaries, the
“Company”), of its obligations under the Employment Agreement dated as of May 28, 2014 (the “Agreement”), do hereby release and forever discharge as of the date hereof the Company and its respective affiliates
and all present, former and future managers, directors, officers, employees, successors and assigns of the Company and its affiliates and direct or indirect owners (collectively, the “Released Parties”) to the extent
provided below (this “General Release”). The Released Parties are intended to be third-party beneficiaries of this General Release, and this General Release may be enforced by each of them in accordance with the terms hereof in
respect of the rights granted to such Released Parties hereunder. Terms used herein but not otherwise defined shall have the meanings given to them in the Agreement. 

1.    I understand that any payments or benefits paid or granted to me under Section 8 of the Agreement represent, in
part, consideration for signing this General Release and are not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive certain of the payments and benefits specified in Section 8 of the
Agreement unless I execute this General Release and do not revoke this General Release within the time period permitted hereafter. Such payments and benefits will not be considered compensation for purposes of any employee benefit plan, program,
policy or arrangement maintained or hereafter established by the Company or its affiliates. 
 2.    Except as provided
in paragraphs 4 and 5 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, I knowingly and voluntarily (for myself, my heirs, executors, administrators and assigns) release
and forever discharge the Company and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages,
liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date that this General Release becomes
effective and enforceable) and whether known or unknown, suspected, or claimed against the Company or any of the Released Parties which I, my spouse, or any of my heirs, executors, administrators or assigns may have, including, without limitation,
claims which arise out of or are connected with my employment with, or my separation or termination from, the Company (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as
amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family
and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; any applicable Executive Order Programs; the Fair Labor Standards Act; or their state or local counterparts;
or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any policies,
practices or procedures of the Company; or any claim for wrongful discharge, breach of contract, 

  
 -1- 

 
infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively
referred to herein as the “Claims”). 
 3.    I represent that I have made no assignment or transfer of
any right, claim, demand, cause of action, or other matter covered by paragraph 2 above. 
 4.    I agree that this
General Release does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release. I acknowledge and agree that my separation from
employment with the Company in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 

5.    I agree that I hereby waive all rights to sue or obtain equitable, remedial or punitive relief from any or all
Released Parties of any kind whatsoever in respect of any Claim, including, without limitation, reinstatement, back pay, front pay, and any form of injunctive relief. Notwithstanding the above, I further acknowledge that I am not waiving and am not
being required to waive any right that cannot be waived under law, including the right to file an administrative charge or participate in an administrative investigation or proceeding; provided, however, that I disclaim and waive any
right to share or participate in any monetary award resulting from the prosecution of such charge or investigation or proceeding. Additionally, I am not waiving (i) any right to the Accrued Benefits or any severance benefits to which I am
entitled under the Agreement, (ii) any claim relating to directors’ and officers’ liability insurance coverage or any right of indemnification under the Company’s organizational documents or otherwise, or (iii) my rights as
an equity or security holder in the Company or its affiliates. 
 6.    In signing this General Release, I acknowledge
and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release shall be given full force and effect according to each and all of its express terms
and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state or local statute that expressly limits the effectiveness of a general release of unknown, unsuspected and unanticipated Claims), if any, as well as
those relating to any other Claims hereinabove mentioned or implied. I acknowledge and agree that this waiver is an essential and material term of this General Release and that without such waiver the Company would not have agreed to the terms of
the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, or in the event I should seek to recover against the Company in any Claim brought by a governmental agency on my behalf, this General
Release shall serve as a complete defense to such Claims to the maximum extent permitted by law. I further agree that I am not aware of any pending claim of the type described in paragraph 2 above as of the execution of this General Release. 

7.    I agree that neither this General Release, nor the furnishing of the consideration for this General Release, shall
be deemed or construed at any time to be an admission by the Company, any Released Party or myself of any improper or unlawful conduct. 

  
 -2- 

 8.    I agree that if I violate this General Release by suing the
Company or the other Released Parties, I will pay all costs and expenses of defending against the suit incurred by the Released Parties, including reasonable attorneys’ fees. 

9.    I agree that this General Release and the Agreement are confidential and agree not to disclose any information
regarding the terms of this General Release or the Agreement, except to my immediate family and any tax, legal or other counsel I have consulted regarding the meaning or effect hereof or as required by law, and I will instruct each of the foregoing
not to disclose the same to anyone. 
 10.    Any non-disclosure provision in
this General Release does not prohibit or restrict me (or my attorney) from (i) making any disclosure of information required by law, including providing truthful testimony if required to do so by court order or legal process,
(ii) cooperating, participating or assisting in any investigation or proceeding brought by any federal, state or local regulatory enforcement agency or legislative body, or any self-regulatory organization to the extent required by law, or
(iii) responding to any inquiry about this General Release or its underlying facts and circumstances by the Securities and Exchange Commission (SEC), the Financial Industry Regulatory Authority (FINRA), any other
self-regulatory organization or any governmental entity. 
 11.    I hereby
acknowledge that Sections 8 through 22 of the Agreement shall survive my execution of this General Release. 
 12.    I
represent that I am not aware of any claim by me other than the claims that are released by this General Release. I acknowledge that I may hereafter discover claims or facts in addition to or different than those which I now know or believe to exist
with respect to the subject matter of the release set forth in paragraph 2 above and which, if known or suspected at the time of entering into this General Release, may have materially affected this General Release and my decision to enter into it.

 13.    Notwithstanding anything in this General Release to the contrary, this General Release shall not relinquish,
diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any Released Party of the Agreement after the date hereof. 

14.    This General Release may not be changed orally and no modification, amendment or waiver of any provision contained
in this General Release, or any future representation, promise or condition in connection with the subject matter of this General Release shall be binding upon me unless made in writing signed by both parties. 

15.    Whenever possible, each provision of this General Release shall be interpreted in, such manner as to be effective
and valid under applicable law, but if any provision of this General Release is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall
not affect any other provision or any other jurisdiction, but this General Release shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

 BY SIGNING THIS GENERAL RELEASE, I REPRESENT AND AGREE THAT:
