B.                                    The Company will enter into an Exchange Agreement with JEH LLC and the Existing Owners (the “Exchange Agreement”) pursuant to which the Existing Owners and their permitted transferees will have the right, subject to the terms of the Exchange Agreement, to exchange their JEH LLC Units (together with a corresponding number of shares of Class B Common Stock of the Company) for shares of Class A Common Stock (or, at JEH LLC’s option, for a cash payment) on a one-for-one basis, subject to certain adjustments.

C.                                    In connection with the Reorganization, the certificate of incorporation of the Company will be amended and restated (as amended and restated, the “Company Restated Certificate of Incorporation”) and the bylaws of the Company will be amended and restated (as amended and restated, the “Company Restated Bylaws,” and together with the Company Restated Certificate of Incorporation, the JEH LLC Third Amended and Restated LLC Agreement and the Exchange Agreement, the “Transaction Documents”).

7.                                      Indemnification and Contribution.

(a)                                 Indemnification of the Underwriters.  Each of the Company and JEH LLC agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of 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, reasonable legal fees and other expenses incurred in connection with any suit, action or proceeding or any claim asserted, as such fees and expenses are incurred), joint or several, that arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or caused by any omission or alleged omission to state therein a material fact required to be stated therein or necessary in order to make the statements therein, not misleading, or (ii) any untrue statement or alleged untrue statement of a material fact contained in (A) the Prospectus (or any amendment or supplement thereto), (B) any Issuer Free Writing Prospectus, (C) any “issuer information” filed or required to be filed pursuant to Rule 433(d) under the Securities Act or any road show as defined in Rule 433(h) under the Securities Act (a “road show”) (in the case of (B) or (C), taken together with the Pricing Disclosure Package) or (D) the Pricing Disclosure Package, or caused by any omission or alleged omission to state therein a material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, in each case except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Company by such Underwriter through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter consists of the information described as such in subsection (b) below.

Indemnification of QIU.  The Company hereby confirms its engagement of Barclays Capital Inc. as, and Barclays Capital Inc. hereby confirms its agreement with the Company to render services as, a “qualified independent underwriter” within the meaning of Financial Industry Regulatory Authority, Inc. (“FINRA”) Rule 5121(f)(12) with respect to the offering and sale of the Shares.  Barclays Capital Inc., in its capacity as qualified independent underwriter and not otherwise, is referred to herein as the “QIU.” The Company will indemnify and hold harmless Barclays Capital Inc., in its capacity as QIU, against any losses, claims, damages or liabilities, joint or several, to which the QIU may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) an untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement or the Prospectus, or any amendment or supplement thereto, (ii) the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading or (iii) any act or omission to act

23

or any alleged act or omission to act by Barclays Capital Inc. as QIU in connection with any transaction contemplated by this Agreement or undertaken in preparing for the purchase, sale and delivery of the Shares, except with respect to clauses (i) and (ii) for any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information furnished to the Company by Barclays Capital Inc., in its capacity as QIU, for use therein, and except with respect to clause (iii) to the extent that any such loss, claim, damage or liability results from the gross negligence or bad faith of Barclays Capital Inc. in performing the services as QIU, and will reimburse the QIU for any legal or other expenses reasonably incurred by the QIU in connection with investigating or defending any such action or claim as such expenses are incurred.

(b)                                 Indemnification of the Company and JEH LLC.  Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, JEH LLC and their respective directors, the Company’s officers who signed the Registration Statement and each person, if any, who controls the Company or JEH LLC within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company by such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus, any road show or the Pricing Disclosure Package, it being understood and agreed upon that the only such information furnished by any Underwriter consists of the following information in the Prospectus furnished on behalf of each Underwriter:  the concession and reallowance figures appearing in the third paragraph under the caption “Underwriting” and the information contained in the fourteenth and fifteenth paragraphs under the caption “Underwriting.”

(c)                                  Notice and Procedures.  If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above.  If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred.  In any such proceeding, any Indemnified Person 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 Person (other than reasonable costs of investigation) unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interest between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceedings in the same jurisdiction, be liable for the reasonable fees and expenses of more than one

24

separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be paid or reimbursed as they are incurred; provided, however that if indemnity may be sought pursuant to the second paragraph of Section 7(a) above in respect of such proceeding, then in addition to such separate firm of the Underwriters, their affiliates and such control persons of the Underwriters, the Indemnifying Person shall be liable for the reasonable fees and expenses of not more than one separate firm (in addition to any local counsel) for Barclays Capital Inc. in its capacity as a “qualified independent underwriter”, its affiliates, directors, officers and all persons, if any, who control Barclays Capital Inc., in its capacity as QIU, within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act.  Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by J. P. Morgan Securities LLC and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company.  The Indemnifying Person 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 providing for an indemnifiable loss hereunder, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment to the extent provided herein. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person 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 the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d)                                 Contribution.  If the indemnification provided for in paragraphs (a) and (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities required to be indemnified thereby, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person 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 Company and JEH LLC, on the one hand, and the Underwriters on the other, from the offering of the Shares or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and JEH LLC, on the one hand, and the Underwriters on the other, 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 and JEH LLC, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Shares and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Shares.  The relative fault of the Company and JEH LLC, on the one hand, and the Underwriters on the other, 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 and JEH LLC or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

25

(e)                                  Limitation on Liability.  The Company, JEH LLC and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (d) above 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 paragraph (d) above.  The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim.  Notwithstanding the provisions of paragraphs (d) and (e), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Shares exceeds the amount of any damages that such Underwriter has otherwise been 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 Underwriters’ obligations to contribute pursuant to paragraphs (d) and (e) are several in proportion to their respective purchase obligations hereunder and not joint.

(f)                                   Non-Exclusive Remedies.  The remedies provided for in this Section 7 paragraphs (a) through (e) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

8.                                      Effectiveness of Agreement.  This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

9.                                      Termination.  This Agreement may be terminated in the absolute discretion of the Representatives, by notice to the Company, if after the execution and delivery of this Agreement and prior to the Closing Date or, in the case of the Option Shares, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the Exchange, the American Stock Exchange, the Nasdaq Stock Market, the Chicago Board Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by federal or New York State authorities or a material disruption in securities settlement or clearance services in the United States shall have occurred; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Shares on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

10.                               Defaulting Underwriter.

(a)                                 If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Shares that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Shares by other persons satisfactory to the Company on the terms contained in this Agreement.  If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Shares on such terms.  If other persons become obligated or agree to purchase the Shares of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the Closing Date or the Additional

26

Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes.  As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 10, purchases Shares that a defaulting Underwriter agreed but failed to purchase.

(b)                                 If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Shares to be purchased on such date, then the Company shall have the right to require each non-defaulting Underwriter to purchase the number of Shares that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Shares that such Underwriter agreed to purchase on such date) of the Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c)                                  If, after giving effect to any arrangements for the purchase of the Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate number of Shares that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Shares to be purchased on such date, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Shares on the Additional Closing Date shall terminate without liability on the part of the non-defaulting Underwriters.  Any termination of this Agreement pursuant to this Section 10 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 11 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

Form of Opinion of Counsel for Jones Energy, Inc.

(a)                                 The Registration Statement has been declared effective under the Securities Act; each of the Preliminary Prospectus and the Prospectus was filed with the Commission pursuant to Rule 424(b) under the Securities Act in the manner and within the time period required by Rule 424(b); and to the knowledge of such counsel no order suspending the effectiveness of the Registration Statement has been issued and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Company or in connection with the offering is pending or threatened by the Commission.

(b)                                 The Company, JEH LLC and each of the subsidiaries set forth on Schedule I (the “Subsidiaries”) are validly existing and in good standing under the laws of their respective jurisdictions of organization, are duly qualified to do business and are in good standing in each jurisdiction set forth opposite the name of such entity on Schedule I, and have all power and authority necessary to own or hold their respective properties and to conduct the businesses in which they are engaged, as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, in each case except where the failure to be so qualified or have such power or authority would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(c)                                  After giving effect to the Reorganization, the Company will have an authorized capitalization as set forth in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the heading “Capitalization;” all the issued shares of capital stock of the Company (including the Shares being delivered at the applicable Closing Date) have been duly and validly authorized and issued and are, or in the case of the Shares being delivered at the applicable Closing Date, when issued and delivered against payment therefor as provided in the Underwriting Agreement, will be validly issued, fully paid and non-assessable.

(d)                                 Except as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, there are no options, warrants, preemptive rights, rights of first refusal or other rights to subscribe for or to purchase, any equity securities of the Company pursuant to the Company Restated Certificate of Incorporation, the Company Restated Bylaws or any other agreement or instrument filed as an exhibit to the Registration Statement.

(e)                                  After giving effect to the Reorganization, the Company will own [·]% of the issued and outstanding JEH LLC Units (or such additional amount to reflect the exercise of the Underwriters’ option to purchase Option Shares pursuant to Section 2 of the Underwriting Agreement); such JEH LLC Units will be duly and validly authorized and issued, fully paid and non-assessable (except as such nonassessability may be affected by Sections 18-607 and 18-804 of the Delaware LLC Act, as applicable, and limited to the extent set forth in JEH LLC’s organizational documents) and will be owned by the Company, free and clear of any lien, charge, encumbrance or security interest (each, a “Lien”) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the Company as the debtor is on file in the office of the Secretary of State of the State of Delaware, other than those Liens that may exist pursuant to the Credit Agreement or the Term Loan.

(f)                                   Each of the Company and JEH LLC has all requisite corporate or limited liability company power and authority to execute and deliver each of the Transaction Documents to which it is a party and to perform its obligations thereunder; and all corporate or limited liability company action required to be taken for the due and proper authorization, execution and delivery by the Company and JEH LLC of each of the

A-1

Transaction Documents to which it is a party and the consummation by it of the transactions contemplated thereby has been validly taken.

(g)                                  The Underwriting Agreement has been duly authorized, executed and delivered by the Company and JEH LLC.

(h)                                 Each Transaction Document to which the Company and JEH LLC, as applicable, are a party, assuming the due authorization, execution and delivery by the other parties thereto, constitutes a valid and legally binding agreement of each of the Company and JEH LLC, as applicable, enforceable against each of the Company and JEH LLC in accordance with its terms, provided that the enforceability thereof may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law), and (ii) public policy, applicable law relating to fiduciary duties and indemnification and an implied covenant of good faith and fair dealing.

(i)                                     Each Transaction Document conforms in all material respects to the description thereof contained in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

(j)                                    None of (i) the execution, delivery and performance by the Company and JEH LLC of each of the Transaction Documents to which it is a party, (ii) the issuance and sale by the Company of the Shares being delivered on the Closing Date or the Additional Closing Date, as the case may be, or (iii) the consummation of the transactions contemplated by the Transaction Documents, including the Reorganization, will (A) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any Lien (other than Liens arising under or in connection with the Credit Agreement and Term Loan) upon any property or assets of the Company, JEH LLC and each of the Subsidiaries under any agreement or other instrument filed as an exhibit to the Registration Statement, (B) constitute a violation of the provisions of the charter or by-laws or similar organizational documents of the Company, JEH LLC or any of the Subsidiaries or (C) result in the violation of the DGCL, the Delaware LLC Act, the laws of the State of Texas or federal law applicable to the Company, JEH LLC or any of the Subsidiaries, except, in the case of clauses (A) and (C) above, for such conflict, breach, violation, default or Lien that would not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect, and except in the case of clause (C) for federal or state securities laws or anti-fraud laws.

(k)                                 No consent, approval, authorization, order, registration or qualification (“consent”) of or with any Delaware, Texas or federal court, arbitrator, governmental agency or regulatory authority having jurisdiction over the Company, JEH LLC and each of the Subsidiaries under the DGCL, the Delaware LLC Act, the laws of the State of Texas or federal law, is required for the execution, delivery and performance by the Company and JEH LLC of each of the Transaction Documents to which it is a party, the issuance and sale by the Company of the Shares being delivered on the Closing Date or the Additional Closing Date, as the case may be, or the consummation by the Company and JEH LLC of the transactions contemplated by the Transaction Documents, except (i) for registration of the Shares under the Securities Act and consents required under the Exchange Act, applicable state securities or “Blue Sky” laws, and the rules of the FINRA in connection with the purchase and distribution of the Shares by the Underwriters (as to which such counsel need not express an opinion), (ii) for such consents that have been obtained or made, (iii) for any such consents the absence or omission of which would not reasonably be expected to have a Material Adverse Effect or (iv) as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

A-2

(l)                                     The statements in the Registration Statement, the Pricing Disclosure Package and the Prospectus under the headings “Material U.S. federal income and estate tax considerations for non-U.S. holders,” “Description of capital stock,” and in the Registration Statement in item 14, insofar as they describe the terms of the Shares, provisions of federal statutes, rules or regulations or the DGCL or any contracts and other legal instruments, are accurate in all material respects.

(m)                             To the knowledge of such counsel, (A) there are no current or pending legal, governmental or regulatory actions, suits or proceedings that are required under the Securities Act to be described in the Registration Statement or the Prospectus and that are not so described in the Registration Statement, the Pricing Disclosure Package and the Prospectus and (B) there are no contracts or other instruments that are required under the Securities Act to be filed as exhibits to the Registration Statement or described in the Registration Statement or the Prospectus and that have not been so filed as exhibits to the Registration Statement or described in the Registration Statement, the Pricing Disclosure Package and the Prospectus.

(n)                                 After giving effect to the application of the proceeds received by the Company and JEH LLC from the offering and sale of the Shares as described in the Registration Statement, the Pricing Disclosure Package and the Prospectus, the Company will not be required to register as an “investment company” or an entity “controlled” by an “investment company” within the meaning of the Investment Company Act.

In rendering such opinion, such counsel may (i) rely in respect of matters of fact upon certificates of officers and employees of the Company and JEH LLC and upon information obtained from public officials, (ii) assume that all documents submitted to such counsel as originals are authentic, that all copies submitted to such counsel conform to the originals thereof, and that the signatures on all documents examined by such counsel are genuine, (iii) state that its opinion is limited to matters governed by federal law, the Texas Limited Liability Company Act, the Delaware General Corporation Law and the Delaware LLC Act, (iv) with respect to the opinions expressed as to the good standing or due qualification or registration as a foreign corporation or limited liability company, as the case may be, of the Company, JEH LLC and each of their respective subsidiaries, state that such opinions are based upon certificates of good standing provided by the Secretary of State of the state of formation and certificates of foreign qualification or registration provided by the Secretary of State of the states listed on an annex to be attached to such counsel’s opinion (each of which shall be dated as of a date not more than fourteen days prior to the Closing Date or the Additional Closing Date, as applicable, and shall be provided to counsel to the Underwriters), (v) state that they express no opinion with respect to (A) any permits to own or operate any real or personal property or (B) state or local taxes or tax statutes to which any of the members of JEH LLC may be subject; and (vi) with respect to the opinions expressed in paragraphs (c) and (d) relating to the existence of any Lien for which a financing statement under the Uniform Commercial Code is on file, rely solely upon such counsel’s review of reports, dated as of recent dates, prepared by CT Lien Solutions, a Wolters Kluwer Company, purporting to describe all financing statements on file as of the dates thereof in the office of the Secretary of State of the State of Delaware, naming the Company or JEH LLC as debtor.

In addition, such counsel shall make statements to the following effect:

Such counsel has reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and has participated in conferences with officers and other representatives of each of the Company and JEH LLC, representatives of its independent registered public accounting firm, representatives of the independent reserve engineers of the Company and JEH LLC and with the Underwriters’ representatives and their counsel, at which the contents of the Registration Statement, the Pricing Disclosure Package, the Prospectus and related matters were discussed.  The purpose of such counsel’s professional engagement was not

A-3

to establish or confirm factual matters set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus, and such counsel has not undertaken to verify independently any of the factual matters in such documents.  Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus involve matters of a non-legal nature.  Accordingly, such counsel is not passing upon, and does not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent stated in paragraph (l) above).  Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel advises the Underwriters that:

(a)                                 the Registration Statement, as of the latest effective date, the Preliminary Prospectus, as of the Applicable Time, and the Prospectus, as of its date and as of the applicable Closing Date, appear on their face to be appropriately responsive in all material respects to the requirements of the Securities Act and the rules and regulations of the Commission thereunder; and

(b)                                 nothing came to such counsel’s attention that caused it to believe that:

(1)                                the Registration Statement, as of the latest Effective Time, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(2)                                the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(3)                                the Prospectus, as of its date or as of the applicable Closing Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case such counsel has not been asked to, and does not, express any belief with respect to (a) the financial statements and schedules or other financial or accounting information contained or included therein or omitted therefrom, (b) the summary reserve report of independent reserve engineer and reserve information contained or included therein or omitted therefrom, or (c) representations and warranties and other statements of fact contained in the exhibits to the Registration Statement.

The opinion of Baker Botts L.L.P. described above shall be rendered to the Underwriters at the request of the Company and shall so state therein.

Ladies and Gentlemen:

The undersigned understands that you, as Representatives of the several Underwriters, propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Jones Energy, Inc., a Delaware corporation (the “Company”), providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of shares of Class A common stock, $0.001 per share par value, of the Company (the “Securities”). Capitalized terms used herein and not otherwise defined shall have the meanings set forth in the Underwriting Agreement.

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of each of J. P. Morgan Securities LLC and Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, during the period ending 180 days after the date of the prospectus 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, or otherwise transfer or dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any shares of Class A Common Stock, $0.001 per share par value, of the Company (the “Common Stock”) or any securities convertible into or exercisable or exchangeable for Common Stock (including without limitation, Common Stock or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of a stock option or warrant), or publicly disclose the intention to make any offer, sale, pledge, disposition or filing (other than any filings on Form S-8 relating to the Company Stock Plans), (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Stock or such other securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other securities, in cash or otherwise or (3) make any demand for or exercise any right with respect to the registration of any shares of Common Stock or any security convertible into or exercisable or exchangeable for Common Stock, in each case other than (A) the Securities to be sold by the undersigned pursuant to the Underwriting Agreement, (B)  any JEH LLC Units exchanged by the Existing Owners under the

Exchange Agreement in connection with any exercise by the Underwriters of the option to purchase Option Shares, (C) transfers of shares of Common Stock as a bona fide gift or gifts, and (D) distributions of shares of Common Stock to members, partners or stockholders of the undersigned; provided that in the case of any transfer or distribution pursuant to clause (C) or (D), each donee or distributee shall execute and deliver to the Representatives a lock-up letter in the form of this paragraph; and provided, further, that in the case of any transfer or distribution pursuant to clause (C) or (D), no filing by any party (donor, donee, transferor or transferee) under the Securities Exchange Act of 1934, as amended, or other public announcement shall be required or shall be made voluntarily in connection with such transfer or distribution (other than a filing on a Form 5 made after the expiration of the 180-day period referred to above).

If the undersigned is an officer or director of the Company, (i) each of J.P.

Morgan Securities LLC and Barclays Capital Inc., on behalf of the Underwriters, 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 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.

Notwithstanding the foregoing, if (1) during the last 17 days of the 180-day restricted period, the Company issues an earnings release or material news or a material event relating to the Company occurs; or (2) prior to the expiration of the 180-day restricted period, the Company announces that it will release earnings results during the 16-day period beginning on the last day of the 180-day period, the restrictions imposed by this Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release, announcement of the material news or occurrence of the material event.

In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the securities described herein, are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Letter Agreement.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Letter Agreement.  All authority herein conferred or agreed to be conferred and any obligations of the undersigned shall be binding upon the successors, assigns, heirs or personal representatives of the undersigned.

The undersigned understands that, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Common Stock to be sold thereunder, the undersigned shall be released from, all obligations under this Letter Agreement.  The undersigned understands that the Underwriters are entering into the Underwriting Agreement and proceeding with the Public Offering in reliance upon this Letter Agreement.

This Letter Agreement and any claim, controversy or dispute arising under or related to this Letter Agreement shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of laws principles thereof.
