(f)    If the Time of Sale Prospectus is being used to solicit offers to buy the Shares at a time when the Prospectus is not yet available to prospective purchasers and any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Time of Sale Prospectus in order to make the statements therein, in the light of the circumstances, not misleading, or if any event shall occur or condition exist as a result of which the Time of Sale Prospectus conflicts with the information contained in the Registration Statement then on file, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Time of Sale Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to any dealer upon request, either amendments or supplements to the Time of Sale Prospectus so that the statements in the Time of Sale Prospectus as so amended or supplemented will not, in the light of the circumstances when the Time of Sale Prospectus is delivered to a prospective purchaser, be misleading or so that the Time of Sale Prospectus, as amended or supplemented, will no longer conflict with the Registration Statement, or so that the Time of Sale Prospectus, as amended or supplemented, will comply with applicable law.

(g)    If, during such period after the first date of the public offering of the Shares as in the opinion of counsel for the Underwriters the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is required by law to be delivered in connection with sales by an Underwriter or dealer, any event shall occur or condition exist as a result of which it is necessary to amend or supplement the Prospectus in order to make the statements therein, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, not misleading, or if, in the opinion of counsel for the Underwriters, it is necessary to amend or supplement the Prospectus to comply with applicable law, forthwith to prepare, file with the Commission and furnish, at its own expense, to the Underwriters and to the dealers (whose names and addresses the Representatives will furnish to the Company) to which Shares may have been sold by the Representatives on behalf of the Underwriters and to any other dealers upon request, either amendments or supplements to the Prospectus so that the statements in the Prospectus as so amended or supplemented will not, in the light of the circumstances when the Prospectus (or in lieu thereof the notice referred to in Rule 173(a) of the Securities Act) is delivered to a purchaser, be misleading or so that the Prospectus, as amended or supplemented, will comply with applicable law.

28

(h)    The Company will arrange for the qualification of the Shares for sale under the laws of such jurisdictions as the Representatives designate and will continue such qualifications in effect so long as required for the distribution.

(i)    To make generally available to the Company’s security holders and to the Representatives as soon as practicable an earnings statement covering a period of at least twelve months beginning with the first fiscal quarter of the Company occurring after the date of this Agreement which shall satisfy the provisions of Section 11(a) of the Securities Act and the rules and regulations of the Commission thereunder.

(j)    To file with the Commission such information on Form 10-Q or Form 10-K as may be required by Rule 463 under the Securities Act.

(p)    The Company Parties will deliver to each Underwriter (or its agent), on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company Parties undertake to provide such additional supporting documentation as each Underwriter may reasonably request in connection with the verification of the foregoing Certification.

8.    Expenses. Whether or not the transactions contemplated in this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all expenses incident to the performance of their obligations under this Agreement, including: (i) the fees, disbursements and expenses of the Company’s counsel and the Company’s accountants in connection with the registration and delivery of the Shares under the Securities Act and all other fees or expenses in connection with the preparation and filing of the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, any free writing prospectus prepared by or on behalf of, used by, or referred to by the Company and amendments and supplements to any of the foregoing, including all printing costs associated therewith, and the mailing and delivering of copies thereof to the Underwriters and dealers, in the quantities hereinabove specified, (ii) all costs and expenses related to the transfer and delivery of the Shares to the Underwriters, including any transfer or other taxes payable thereon, (iii) the reasonable, documented cost of printing or producing any Blue Sky or legal investment memorandum in connection with the offer and sale of the Shares under state securities laws and all expenses in connection with the qualification of the Shares for offer and sale under state securities laws as provided in Section 7(h) hereof, including filing fees and the reasonable, documented fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky or legal investment memorandum, (iv) all filing fees and the reasonable fees and disbursements of counsel to the Underwriters incurred in connection with the review and qualification of the offering of the Shares by FINRA (provided that the amount payable by the Company pursuant to subsection (iv) for the fees and disbursements of counsel to the Underwriters shall not exceed $30,000 and provided further that the Underwriters shall provide reasonable supporting documentation to the Company for all amounts payable by the Company pursuant to subsection (iv)), (v) all fees and expenses in connection with the preparation and filing of the registration statement on Form 8-A relating to the shares of Class A Common Stock and all costs and expenses incident to listing the Shares on the NYSE, (vi) the cost of printing certificates representing the Shares, (vii) the costs and charges of any transfer agent, registrar or depositary, (viii) the costs and expenses of the Company relating to investor presentations on any “road show” undertaken in connection with the marketing of the offering of the Shares, including, without limitation, expenses associated with the preparation or dissemination of any electronic road show, expenses associated with the production of road show slides and graphics, fees and expenses of any consultants engaged in connection with the road show presentations with the prior written approval of the Company, travel and lodging expenses of the representatives and officers of the Company and any such consultants, and 50.0% of the cost of any aircraft chartered in connection with the road show (and the Underwriters will pay the remaining 50.0% of the cost of such aircraft), (ix) the document production charges and expenses associated with printing this Agreement, (x) the reasonable, out-of-pocket fees and expenses of the QIU acting in its capacity as such (provided that the amount payable by the Company pursuant to this subsection (x) for

30

the fees and expenses of the QIU acting in its capacity as such shall not exceed $10,000; provided, further, that this subsection (x) shall not limit or otherwise impact the QIU’s right to indemnification as set forth under Article X for acting as the “qualified independent underwriter”) and (xi) all other costs and expenses incident to the performance of the obligations of the Company hereunder for which provision is not otherwise made in this Section 8. It is understood, however, that except as provided in this Section 8, Section 10, Section 11 and the last paragraph of Section 12 below, the Underwriters will pay all of their costs and expenses, including fees and disbursements of their counsel, stock transfer taxes payable on resale of any of the Shares by them and any advertising expenses connected with any offers they may make.

9.    Covenants of the Underwriters. Each Underwriter severally covenants with the Company not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

10.    Indemnity and Contribution. (a) The Company Parties agree, jointly and severally, to indemnify and hold harmless each Underwriter, its officers, directors, employees, agents, each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act, and each affiliate of any Underwriter within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any “road show” as defined in Rule 433(h) under the Securities Act (a “road show”), or the Prospectus or any amendment or supplement thereto, or any Written Testing-the-Waters Communication or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages or liabilities are caused by any such untrue statement or omission or alleged untrue statement or omission based upon information relating to any Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use therein.

(b)    Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) caused by any untrue statement

31

or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show or the Prospectus or any amendment or supplement thereto, or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, but only with reference to information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any free writing prospectus, road show, or the Prospectus or any amendment or supplement thereto.

(c)    Without limitation and in addition to its obligation under the other subsections of this Section 10, the Company agrees to indemnify and hold harmless the QIU, its directors, officers, employees, agents and each person, if any, who controls the QIU within the meaning of Section 15 and Section 20 of the Exchange Act against any and all losses, claims, damages or liabilities arising out of or based upon the QIU’s acting as a “qualified independent underwriter” (within the meaning of Rule 5121(f)(12) of FINRA) in connection with the offering contemplated by this Agreement, and agrees to reimburse each such indemnified person for any legal or other expense reasonably incurred by them in connection with investigating or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not the QIU is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability results from the gross negligence or willful misconduct of the QIU.

(d)    In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a), 10(b) or 10(c) such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed to the retention of such counsel or (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the

32

indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act and (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within the meaning of either such Section. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Representatives. In the case of any such separate firm for the Company, and such directors, officers and control persons of the Company, such firm shall be designated in writing by the Company. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding.

(e)    Notwithstanding anything contained herein to the contrary, if indemnity may be sought pursuant to Section 10(c) in respect of such action or proceeding, then in addition to such separate firm for the indemnified parties, the indemnifying party shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for the QIU in its capacity as a “qualified independent underwriter” and all persons, if any, who control the QIU within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act.

33

(f)    To the extent the indemnification provided for in Sections 10(a), 10(b) or 10(c) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 10(f)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 10(f)(i) above but also the relative fault of the indemnifying party or parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company Parties on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as the net proceeds from the offering of the Shares (before deducting expenses) received by the Company and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the Company Parties on the one hand and the Underwriters on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company Parties or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 10 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint. The relative benefits received by the QIU with respect to the offering contemplated by this Agreement shall, for purposes of this Section 10(f), be deemed to be equal to the compensation received by the QIU for acting in such capacity. In addition, notwithstanding the other provisions of this Section 10(f), the QIU shall not be required to contribute any amount in excess of the compensation received by the QIU for acting in such capacity.

(g)    The Company Parties and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(f). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(f) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been

34

required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(h)    The indemnity and contribution provisions contained in this Section 10 and the representations, warranties and other statements of the Company contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this Agreement, (ii) any investigation made by or on behalf of any Underwriter, the QIU, the Company Parties or any of their respective representatives, officers, directors, employees, agents or any person controlling any of the foregoing and (iii) acceptance of and payment for any of the Shares.

11.    Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company Parties, if after the execution and delivery of this Agreement and prior to or on the Closing Date or any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the NYSE, the NYSE MKT, the NASDAQ Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

12.    Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule I bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused

35

to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 12 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter or the Company. In any such case either the Representatives or the Company shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Company Parties to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Company shall be unable to perform its obligations under this Agreement, the Company Parties will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

Ladies and Gentlemen:

The undersigned understands that Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC and ▇▇▇▇▇▇ ▇▇▇▇▇▇▇ & Co. LLC (the “Representatives”) proposes to enter into an Underwriting Agreement (the “Underwriting Agreement”) with, inter alios, Vine Energy Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters, including the Representatives (the “Underwriters”), of [•] shares (the “Shares”) of the Company’s Class A Common Stock (the “Class A Common Stock”).

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the period commencing on the date hereof and ending 180 days after the date of the final prospectus (the “Restricted Period”) relating to the Public Offering (the “Prospectus”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Class A Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for shares

A-1

of Class A Common Stock, (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of shares of Class A Common Stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of shares of Class A Common Stock or such other securities, in cash or otherwise, or (3) publicly disclose the intention to do any of the foregoing. The foregoing sentence shall not apply to (a) transactions relating to shares of Class A Common Stock or other securities acquired in open market transactions after the completion of the Public Offering, provided that no filing under the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of shares of Class A Common Stock or other securities acquired in such open market transactions, (b) transfers of shares of Class A Common Stock or any security convertible into shares of Class A Common Stock as a bona fide gift, (c) exchanges of shares of Class B Common Stock of the Company for Class A Common Stock pursuant to the Exchange Agreement (as defined in the Underwriting Agreement) or (d) distributions of shares of Class A Common Stock or any security convertible into shares of Class A Common Stock to members, limited partners or stockholders of the undersigned; provided that in the case of any transfer or distribution pursuant to clause (b) through (d), (i) if applicable, each donee or distributee shall sign and deliver a lock-up letter substantially in the form of this letter and (ii) no filing under the Exchange Act, reporting a reduction in beneficial ownership of shares of Class A Common Stock, shall be required or shall be voluntarily made during the Restricted Period, or (e) the establishment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act (a “Rule 10b5-1 Plan”) for the transfer of shares of Class A Common Stock; provided that (i) such plan does not provide for the transfer of shares of Class A Common Stock or securities convertible into, or exchangeable or exercisable for shares of Class A Common Stock during the Restricted Period and (ii) that no party is required to publicly announce, file, or report the establishment of such Rule 10b5-1 Plan in any public report, announcement, or filing with the U.S. Securities and Exchange Commission under the Exchange Act during the Restricted Period and does not otherwise voluntarily effect any such public report, announcement, or filing regarding such Rule 10b5-1 Plan. In addition, the undersigned agrees that, without the prior written consent of the Representatives on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any shares of Class A Common Stock or any security convertible into or exercisable or exchangeable for shares of Class A Common Stock. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Class A Common Stock except in compliance with the foregoing restrictions.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in the offering.

If the undersigned is an officer or director of the Company, (i) the Representatives agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Class A Common Stock, the Representatives will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending

A-2

release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by the Representatives hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration or to an “immediate family member” (as defined in FINRA Rule 5130(i)(5)) and (b) the transferee has agreed in writing to be bound by the same terms described in this letter to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the Public Offering of the Shares and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the Public Offering, the Underwriters are not making a recommendation to you to participate in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

The undersigned understands that the Company and the Underwriters are relying upon this letter in proceeding toward consummation of the Public Offering. The undersigned further understands that this letter is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns.

This letter shall be governed by and construed in accordance with the laws of the State of New York.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

(ix) The Underwriting Agreement has been duly authorized, executed and delivered by the Company Parties.

(x)    Neither (A) the issuance and sale of the Shares, (B) the execution, delivery and performance of the Transaction Agreements by the Company Entities as applicable or (C) the application of the proceeds from the sale of the Shares as described under “Use of Proceeds” in the Time of Sale Prospectus and the Prospectus will (1) result in a breach or result in a default (or an event that, with notice or lapse of time or both, would constitute such an event) under or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or any Subsidiary pursuant to any contract, indenture, mortgage, deed of trust, loan or credit agreement, note, lease or any other agreement or instrument to which the Company or any Subsidiary is a party or by which it or any of them may be bound, or to which any of the property or assets of the Company or any Subsidiary is subject and which are filed as an exhibit to the Registration

C-2

Statement; (2) violate the provisions of the limited liability company agreement, charter or bylaws (or similar organizational documents) of the Company any of its Subsidiaries or (3) violate any federal (based on the limitations set forth in such opinion) rule or regulation identified to us by the Company or its Subsidiaries (we note that none were identified), or the DGCL, except, with respect to clauses (1) and (3), as would not, individually or in the aggregate, reasonably be expected to result in a Material Adverse Effect; it being understood that the counsel expresses no opinion in clause (3) of this paragraph (x) with respect to any federal or state securities, Blue Sky or anti-fraud laws, rules or regulations.

(xi)    The Registration Statement has been declared effective under the Securities Act; to our knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the Commission; and any required filing of the Prospectus pursuant to Rule 424(b) under the Securities Act has been made in the manner and within the time period required by such rule.

(xii)    Except as described in the Time of Sale Prospectus and the Prospectus, no consent, approval, authorization or order of, registration or qualification with any U.S. Federal or Delaware court or governmental agency is required to be obtained or made by (A) the Company for (1) the execution, delivery and performance of the Underwriting Agreement, (2) the compliance by the Company with the terms thereof and (3) the issuance and sale of the Shares by the Company, being delivered on the date hereof pursuant to the Underwriting Agreement, or (B) the Company Entities, as applicable, for the execution, delivery and performance of the Transaction Agreements and the compliance by the Company Entities with the terms thereof except (1) as have been obtained or made, (2) for the registration of the offering and sale of the Shares under the Securities Act, (3) for such consents, approvals, authorizations, orders, registrations or qualifications as may be required under applicable federal or state securities or Blue Sky laws and the approval by FINRA of the underwriting terms and arrangements in connection with the purchase and distribution of the Shares by the Underwriters or (4) for such consents that, if not obtained, have not or would not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

(xiii)    The statements set forth in the Time of Sale Prospectus and the Prospectus under the headings “Business—Regulation of the Natural Gas Industry,” “Business—Regulation of Environmental, Health and Safety Matters,” “Certain Relationships and Related Party Transactions,” “Description of Capital Stock,” and “Shares Eligible for Future Sale” and in the Registration Statement in Item 14, to the extent that they constitute descriptions or summaries of the legal matters or the documents referred to therein, are accurate in all material respects, subject to the assumptions and qualifications set for therein.

(xiv)    The statements contained in the Time of Sale Prospectus and the Prospectus under the caption “Material U.S. Federal Income Tax Considerations for Non-U.S. Holders,” insofar as they purport to constitute summaries of matters of United States federal tax law and regulations or legal conclusions with respect thereto, constitute accurate summaries of the matters described therein in all material respects, subject to the assumptions and qualifications set forth therein.

C-3

(xv)    Each of the Registration Statement, at the time it was declared effective, the Time of Sale Prospectus, as of the date hereof, and the Prospectus, when filed with the Commission pursuant to Rule 424(b) under the Securities Act and, along with any further amendments and supplements thereto, at the Closing Date (in each case other than (A) the financial statements and related schedules, including the notes and schedules thereto and the auditor’s report thereon, (B) the other financial data derived therefrom and (C) oil and natural gas reserve data or reports, in each case included in or omitted from the Registration Statement, the Time of Sale Prospectus and the Prospectus, as to which we express no opinion) appears on their face to comply as to form in all material respects with the requirements of the Securities Act.

We have participated in conferences with representatives of the Company and with representatives of its independent accountants and its independent reserves engineers, the Underwriters and counsel for the Underwriters, at which conferences the contents of the Registration Statement, the Time of Sale Prospectus and the Prospectus and any amendment and supplement thereto and related matters were discussed. Although we have not undertaken to determine independently, and do not assume any responsibility for, or express opinion regarding (other than listed in paragraphs (xiii) and (xiv) above), the accuracy, completeness or fairness of the statements contained in the Registration Statement, the Time of Sale Prospectus and the Prospectus, based upon the participation described above (relying as to factual matters upon statements of fact made to us by representatives of the Company), nothing has come to our attention to cause us to believe that:

except that in each case such counsel need not express any belief with respect to (i) the financial statements and related schedules, including the notes and schedules thereto and the auditors’ reports thereon, (ii) any other financial or accounting information; or (iii) any oil and natural gas reserve data or reports, or any information or estimates derived therefrom, in each case contained in or omitted from the Registration Statement, or included in or omitted from the Time of Sale Prospectus and the Prospectus.
